                        SPECIAL MEETING OF STOCKHOLDERS
 
                  MERGER PROPOSED--YOUR VOTE IS VERY IMPORTANT
 
    The Boards of Directors of Harrah's Entertainment, Inc. and Rio Hotel &
Casino, Inc. have agreed on a merger that will combine Rio's premier Las Vegas
destination resort with Harrah's nationally branded and diversified gaming
operations.
 
    If the merger is completed, Rio stockholders will receive one share of
Harrah's common stock in exchange for each share of Rio common stock that they
own, and Harrah's stockholders will continue to own their existing shares. Based
on closing prices on October 14, 1998, the market value of one share of Harrah's
common stock was $12.13, and the market value of one share of Rio common stock
was $11.75.
 
    We estimate that the shares of Harrah's common stock to be issued to holders
of Rio common stock will represent approximately 19.6% of the outstanding
Harrah's common stock after the merger (exclusive of unexercised stock options).
 
    The merger cannot be completed unless Harrah's stockholders approve the
issuance of Harrah's common stock in the merger and Rio's stockholders approve
the merger. We have scheduled special meetings for our respective stockholders
to vote on such matters.
 
    Whether or not you plan to attend a meeting, please take the time to vote by
completing and mailing the enclosed proxy card to us. If you sign, date and mail
your proxy card without indicating how you want to vote, your proxy will be
counted as a vote in favor of the proposal(s) submitted at your meeting. If you
are a Harrah's stockholder and fail to return your proxy card or vote in person
at the Harrah's Special Meeting, you will not be counted as present or voting on
the proposal to issue Harrah's common stock. If you are a Rio stockholder and
fail to return your proxy card or vote in person at the Rio Special Meeting, the
effect will be a vote against the merger.
 
YOUR VOTE IS VERY IMPORTANT.

ii QUESTIONS AND ANSWERS ABOUT THE MERGER Q: WHY ARE THE TWO COMPANIES PROPOSING TO MERGE? A: Harrah's Entertainment, Inc. and Rio Hotel & Casino, Inc. are proposing to merge because we believe the resulting combination will create a stronger, more competitive gaming company capable of achieving significant revenue synergies and cost savings and better utilizing the product and marketing strengths of the individual companies. Q: WHAT WILL I RECEIVE IN THE MERGER? A: Rio stockholders will receive one share of Harrah's common stock in exchange for each share of Rio common stock that they own. Existing holders of Harrah's common stock will continue to own their shares after the merger. Q: DO THE COMPANIES RECOMMEND VOTING IN FAVOR OF THE MERGER? A: Yes. The Board of Directors of Harrah's recommends that its stockholders vote in favor of the proposed issuance of Harrah's common stock in the merger. The Board of Directors of Rio likewise recommends that its stockholders vote in favor of the proposed merger. Q: WHAT DO I NEED TO DO NOW? A: This Joint Proxy Statement/Prospectus contains important information regarding the proposed merger, as well as information about Harrah's and Rio. It also contains important information about what the management and the Boards of Directors of each of Harrah's and Rio considered in evaluating the proposed merger. We urge you to read this Joint Proxy Statement/Prospectus carefully, including its Annexes, and to consider how the merger affects you as a stockholder. You also may want to review the documents referenced under "Where You Can Find More Information." For information about where to call to get answers to your questions, see "Who Can Help Answer Your Questions?" on page 3. Q: HOW DO I VOTE? A: Simply indicate on your proxy card how you want to vote, sign and mail your proxy card in the enclosed return envelope as soon as possible, so that your shares may be represented at your respective special meeting. If you sign and send in your proxy and do not indicate how you want to vote, your proxy will be counted as a vote for the proposal to issue Harrah's common stock (for Harrah's stockholders) or the merger (for Rio stockholders). If you are a Harrah's stockholder and fail to return your proxy card or vote in person at the Harrah's Special Meeting, you will not be counted as present or voting on the proposal to issue Harrah's common stock and may have the effect of a vote against such proposal. If you are a Rio stockholder and fail to return your proxy card or vote in person at the Rio Special Meeting, the effect will be a vote against the merger. Q: WHEN AND WHERE ARE THE SPECIAL MEETINGS? A: The Harrah's special meeting will take place on November 18, 1998 at 11:00 a.m., local time, at Memphis Botanic Garden, 750 Cherry Road, Memphis, Tennessee. The Rio special meeting will take place on November 18, 1998 at 10:00 a.m., local time, at the Rio Suite Hotel & Casino, 3700 West Flamingo Road, Las Vegas, Nevada. Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY SHARES FOR ME? A: Your broker will not vote your shares for you unless you provide instructions on how to vote. It is important therefore that you follow the directions provided by your broker regarding how to instruct your broker to vote your shares. Q: MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD? A: Yes. You may change your vote at any time before your proxy is voted at your respective stockholder meeting. You may do this in one of three ways. First, you may send a written notice stating that you would like to revoke 1 your proxy. Second, you may complete and submit a new proxy card. If you choose either of these two methods, you must submit your notice of revocation or your new proxy card to Harrah's at the address on page 12 if you are a Harrah's stockholder, or to Rio at the address on page 14 if you are a Rio stockholder. Third, you may attend your respective stockholder meeting and vote in person if you tell the Secretary that you want to cancel your proxy and vote in person. Simply attending your respective stockholder meeting, however, will not revoke your proxy. If you have instructed a broker to vote your shares, you must follow directions received from your broker to change your vote or to vote at your respective stockholder meeting. Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW? A: No. If you are a Rio stockholder, after the merger is completed, we will send you written instructions for exchanging your stock certificates. Harrah's stockholders will not exchange their stock certificates. Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED? A: We are working toward completing the merger as quickly as possible. In addition to stockholder approvals, we must also obtain regulatory approvals, including approvals from gaming regulators in Nevada. We expect to complete the merger by the end of November 1998. Q: WHAT ARE THE TAX CONSEQUENCES OF THE MERGER? A: The merger generally will be tax-free to Rio stockholders for federal income tax purposes. To review the tax consequences to Rio stockholders in greater detail, see page 35. 2 WHO CAN HELP ANSWER YOUR QUESTIONS?

In addition, it owns and operates the Rio Secco Golf Club in Henderson, Nevada. THE STOCKHOLDERS' MEETINGS (PAGES 11 AND 13) The Harrah's Special Meeting will be held at Memphis Botanic Garden, 750 Cherry Road, Memphis, Tennessee, at 11:00 a.m., local time, on November 18, 1998. The Rio Special Meeting will be held at the Rio Suite Hotel & Casino, 3700 West Flamingo Road, Las Vegas, Nevada, at 10:00 a.m., local time, on November 18, 1998. OUR REASONS FOR THE MERGER (PAGE 18) Each of Harrah's and Rio believes that the merger, including the one-for-one stock exchange ratio, is fair and in the best interests of our respective stockholders. We believe the merger offers both companies' stockholders the opportunity to benefit from the revenue synergies and cost savings that are expected to result from combining Rio's premier Las Vegas destination resort with Harrah's existing national distribution of casino offerings. OUR RECOMMENDATIONS TO STOCKHOLDERS (PAGE 18) TO HARRAH'S STOCKHOLDERS: The Harrah's Board of Directors voted unanimously (excluding two directors who were absent and did not vote) to approve the merger agreement and the transactions contemplated thereby. The Harrah's Board believes that the merger is in your best interest and recommends that you vote FOR the proposal to approve the issuance of shares of Harrah's common stock to Rio stockholders in the merger. TO RIO STOCKHOLDERS: The Rio Board of Directors voted unanimously to approve the merger agreement and the transactions contemplated thereby. The Rio Board believes that the merger is in your best interest and recommends that you vote FOR the proposal to approve and adopt the merger agreement and the merger. 4 VOTES REQUIRED (PAGES 11 AND 13) To approve the merger: - a majority of the outstanding shares of Harrah's common stock must cast votes on the proposal to issue shares of Harrah's common stock and a majority of the votes cast must vote in favor of the proposal; and - a majority of the outstanding shares of Rio's common stock must vote in favor of the merger agreement and the merger. Certain directors and holders of shares of Rio's common stock who, as of the record date for the Rio Special Meeting, collectively own approximately 16.6% of the outstanding shares of Rio's common stock have already agreed to vote their shares of Rio's common stock in favor of approving and adopting the merger agreement and the merger. For a description of these stockholder support agreements, see page 53. THE MERGER (PAGE 15) THE MERGER AGREEMENT IS ATTACHED AS ANNEX A TO THIS JOINT PROXY STATEMENT/PROSPECTUS. WE ENCOURAGE YOU TO READ THE MERGER AGREEMENT AS IT IS THE LEGAL DOCUMENT THAT GOVERNS THE MERGER. WHAT RIO STOCKHOLDERS WILL RECEIVE (PAGE 40) As a result of the merger, Rio stockholders will receive one share of Harrah's common stock for each share of Rio common stock that they own. Following the merger, Rio's stockholders will own approximately 19.6% of the then outstanding shares of Harrah's common stock. Rio stockholders should not send in their stock certificates until instructed to do so after the merger is completed. INTERESTS OF CERTAIN PERSONS IN THE MERGER (PAGE 32) A number of executive officers and directors of Rio have interests in the merger that are different from or in addition to your interests. For example, some executive officers have agreements that entitle them to compensation following a change in control of Rio. Consummation of the merger will qualify as a change in control of Rio. Rio estimates that the maximum aggregate payments required to be paid under such agreements to executive officers would be approximately $500,000. A number of executive officers and directors also have stock options which will be converted into options to purchase shares of Harrah's common stock and become immediately exercisable as a result of the merger. It is anticipated that Harrah's will enter into consulting agreements with Anthony A. Marnell II and James A. Barrett, Jr. pursuant to which Harrah's will pay them $600,000 and $400,000, respectively, per year for three years. Harrah's also expects to enter into employment agreements with Ronald J. Radcliffe and I. Scott Bogatz pursuant to which Messrs. Radcliffe and Bogatz will continue to receive compensation and benefits from Harrah's commensurate with their existing compensation and benefits. The specific terms of the employment agreements are being negotiated. Please refer to pages 33 through 34 generally for more information concerning employment arrangements, severance agreements, acceleration of stock options and other arrangements benefiting each company's executive officers and directors. CONDITIONS TO THE MERGER (PAGE 49) The completion of the merger depends upon meeting a number of conditions, including the following: - the approval of the holders of shares of the common stock of each of Harrah's and Rio; - the absence of governmental prohibitions or injunctions to completion of the merger; - obtaining required gaming and other regulatory approvals; - obtaining all required third-party consents; and - the receipt of legal opinions regarding certain tax consequences of the merger. Certain of the conditions to the merger may be waived by the company entitled to assert the condition. 5 TERMINATION OF THE MERGER AGREEMENT (PAGE 51) Harrah's and Rio can mutually agree to terminate the merger agreement without completing the merger, and either of Harrah's or Rio can terminate the merger agreement if any of the following occurs: - the merger is not completed by January 31, 1999, but this deadline may be extended to May 31, 1999 at the election of either of Harrah's or Rio if needed to obtain required regulatory approvals; - a court or other governmental authority permanently prohibits the merger; - the approval of the holders of shares of the common stock of either Harrah's or Rio is not obtained; - the other party breaches or materially fails to comply with any of its representations or warranties or obligations under the merger agreement; or - the other party fails to call its stockholders' meeting by January 31, 1999. Rio can terminate the merger agreement if any of the following occurs: - the Board of Directors of Rio determines, under certain circumstances and before the approval of the merger agreement by its stockholders, that the Board of Directors' fiduciary obligations require acceptance of a superior offer from a third party to acquire Rio; or - Harrah's merges with or sells substantially all of its assets to any person. TERMINATION FEES (PAGE 51) The merger agreement generally requires Harrah's or Rio to pay to the other a termination fee of $22.5 million if the merger agreement terminates under certain circumstances. OPINIONS OF FINANCIAL ADVISORS (PAGES 22 AND 26) In deciding to approve the merger, our Boards of Directors considered opinions from our respective financial advisors as to the fairness of the exchange ratio from a financial point of view. Harrah's received an opinion from its financial advisor, BT Wolfensohn, and Rio received an opinion from its financial advisor, Merrill Lynch, Pierce, Fenner & Smith Incorporated. These opinions are attached as Annexes B and C to this Joint Proxy Statement/Prospectus and you are encouraged to read them. The financial advisors performed several analyses in connection with delivering their opinions. These analyses included (1) comparing Harrah's and Rio historical stock prices, (2) comparing Harrah's and Rio to other publicly traded companies and (3) estimating the relative values of Harrah's and Rio and their contributions to Harrah's based on past and estimated future financial performance. ACCOUNTING TREATMENT (PAGE 34) The merger will be accounted for as a "purchase" in accordance with generally accepted accounting principles. CERTAIN FEDERAL INCOME TAX CONSEQUENCES (PAGE 35) We have structured the merger so that no gain or loss generally will be recognized by you for federal income tax purposes on the exchange of shares of Rio common stock for shares of Harrah's common stock. We have conditioned the merger on our receipt of legal opinions regarding certain tax consequences of the merger. Tax matters are very complicated, and the tax consequences of the merger to you will depend on the facts of your own situation. You should consult your tax advisor for a full understanding of the tax consequences of the merger to you. 6 CERTAIN REGULATORY MATTERS (PAGES 34 AND 36) In order to complete the merger, Rio and Harrah's must make certain filings and receive authorizations from various federal and state governmental agencies in the United States. These filings relate to antitrust matters and gaming and other regulations. It is possible that some of these governmental authorities may impose conditions for granting approval. We cannot predict whether we will obtain all the required regulatory approvals within the time frame contemplated by the merger agreement or without burdensome conditions. NO RIGHT OF DISSENT (PAGE 39) Under Nevada law, Rio stockholders will not have a right to dissent and obtain payment of "fair value" for their shares with respect to the merger agreement. FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE (PAGE 39) We have each made forward-looking statements in this document (and in documents that are incorporated by reference) that are subject to risks and uncertainties. Forward-looking statements include the information concerning possible or assumed future results of operations of Harrah's or Rio, including the anticipated cost savings and revenue synergies from the merger. Also, when we use words such as "believes," "expects," "anticipates" or similar expressions, we are making forward-looking statements. Stockholders should note that many factors could affect the future financial results of Harrah's and Rio, and could cause these results to differ materially from those expressed in our forward-looking statements. These factors include the following: - operating, legal and regulatory risks; - economic, political and competitive forces affecting our businesses; - the risk that we are unable to achieve the cost savings and revenue synergies in the amounts and in the time frames contemplated; and - the risk that our analyses of these risks and forces could be incorrect and/or that the strategies developed to address them could be unsuccessful.

For a more detailed description of purchase accounting, see "The Merger-- Accounting Treatment of the Merger" on page 34. We are providing the following financial information to aid you in your analysis of the financial aspects of the merger. We derived this information from audited financial statements for 1997 and unaudited financial statements for the six months ended June 30, 1998 for both Harrah's and Rio. The information is only a summary of the unaudited pro forma financial information presented on pages 55 to 62 and you should read it in conjunction with our historical financial statements (and related notes) contained in the annual reports and other information that we have filed with the SEC. See "Where You Can Find More Information" on page 76. While this pro forma financial information has been prepared based upon currently available information using assumptions which we believe are appropriate, you should be aware that this pro forma information may not be indicative of what actual results will be in the future or would have been for the periods presented. You should read the notes to the unaudited pro forma financial information beginning on page 59 for further discussion of the assumptions we made to prepare this information.

9 COMPARATIVE HISTORICAL AND PRO FORMA COMBINED PER SHARE DATA We have summarized below the per share information of Harrah's and Rio on a historical, pro forma combined and pro forma equivalent basis. Rio stockholders will receive one share of Harrah's common stock in exchange for each share of Rio common stock. The information set forth below is only a summary and you should read it in conjunction with the historical financial statements and related notes contained in the annual reports and other information that Harrah's and Rio have filed with the SEC. See "Where You Can Find More Information" on page 76.

- ------------------------ (1) Pro forma results to reflect the impact of the Showboat, Inc. acquisition as if that transaction, which was consummated on June 1, 1998, had occurred on the first day of the period. For additional historical financial information regarding Showboat, Inc., see "Where You Can Find More Information" on page 76. (2) The Pro Forma Rio Equivalent per share amounts are identical to the Pro Forma Combined per share amounts because of the one-for-one exchange ratio. (3) The table above combines Harrah's results of operations for the fiscal year ended December 31, 1997 and the results of operations for the six months ended June 30, 1998 with Rio's results of operations for the same periods. The pro forma combined income from continuing operations per share is based on the combined weighted average number of common shares and common share equivalents. Common share equivalents consist of common stock issuable upon the exercise of outstanding options and warrants. (4) We computed historical book value per share by dividing Harrah's unaudited total stockholders' equity as of June 30, 1998 by the number of common shares outstanding as of that date and Rio's unaudited total stockholders' equity as of June 30, 1998 by the number of common shares outstanding as of that date. We computed the Pro Forma Combined book value per share amounts by dividing pro forma stockholders' equity (See "Unaudited Pro Forma Condensed Balance Sheet" on page 58) by the pro forma number of shares of Harrah's common stock outstanding as of June 30, 1998 (without including outstanding options). The pro forma number of shares of Harrah's common stock was calculated as the sum of total shares of Harrah's common stock outstanding and shares of Rio common stock outstanding. (5) Harrah's and Rio have never paid cash dividends during the periods presented, and it is not anticipated that Harrah's will do so in the foreseeable future. 10 THE HARRAH'S SPECIAL MEETING GENERAL This Joint Proxy Statement/Prospectus is being furnished to stockholders of Harrah's Entertainment, Inc., a Delaware corporation ("Harrah's"), as part of the solicitation of proxies by the Harrah's Board of Directors (the "Harrah's Board") for use at a Special Meeting of Stockholders of Harrah's (the "Harrah's Special Meeting") to be held on November 18, 1998 at 11:00 a.m., local time, at Memphis Botanic Garden, 750 Cherry Road, Memphis, Tennessee. This Joint Proxy Statement/Prospectus and the enclosed form of proxy are first being mailed to stockholders of Harrah's on or about October 20, 1998. The purpose of the Harrah's Special Meeting is: (a) to consider and vote upon a proposal to issue up to 28,382,188 shares of common stock, $0.10 par value per share, of Harrah's ("Harrah's Common Stock") pursuant to an Agreement and Plan of Merger, dated as of August 9, 1998 and as amended as of September 4, 1998 (the "Merger Agreement"), by and among Harrah's, HEI Acquisition Corp. III, a Nevada corporation and a direct wholly-owned subsidiary of Harrah's ("Merger Sub"), and Rio Hotel & Casino, Inc., a Nevada corporation ("Rio"), pursuant to which, among other things, (i) Merger Sub will be merged with and into Rio (the "Merger"), with Rio continuing as the surviving corporation and (ii) each outstanding share of common stock, par value $0.01 per share, of Rio ("Rio Common Stock"), other than shares owned by Harrah's or by Rio as treasury stock (which will be cancelled), will be converted into the right to receive one share of Harrah's Common Stock (the "Stock Issuance Proposal"); and (b) to consider such other procedural matters as may properly come before the Harrah's Special Meeting or any adjournments or postponements thereof, including without limitation, potential adjournments or postponements of the Harrah's Special Meeting for the purpose of soliciting additional proxies in order to approve the Stock Issuance Proposal. Each copy of this Joint Proxy Statement/Prospectus mailed to holders of Harrah's Common Stock is accompanied by a form of proxy for use at the Harrah's Special Meeting. The Harrah's Board recommends that stockholders vote FOR the approval of the Stock Issuance Proposal. RECORD DATE AND VOTING Harrah's has fixed the close of business on October 5, 1998 as the record date for the determination of the Harrah's stockholders entitled to notice of and to vote at the Harrah's Special Meeting. Accordingly, only holders of record of Harrah's Common Stock on the record date will be entitled to notice of and to vote at the Harrah's Special Meeting. As of October 5, 1998, there were outstanding and entitled to vote 101,472,081 shares of Harrah's Common Stock (constituting all of the voting stock of Harrah's), which shares were held by approximately 11,824 holders of record. Each holder of record of shares of Harrah's Common Stock on the record date is entitled to one vote per share, which may be cast either in person or by properly executed proxy, at the Harrah's Special Meeting. The presence at the Harrah's Special Meeting, in person or by properly executed proxy, of the holders of a majority of the outstanding shares of Harrah's Common Stock is necessary to constitute a quorum at the Harrah's Special Meeting. Approval of the Stock Issuance Proposal will require the affirmative vote of holders of a majority of the shares of Harrah's Common Stock cast on such matter, provided that the total votes cast represents a majority of the outstanding shares of Harrah's Common Stock. Shares of Harrah's Common Stock represented in person or by proxy will be counted for the purposes of determining whether a quorum is present at the Harrah's Special Meeting. Shares which abstain from voting as to the Stock Issuance Proposal will be treated as shares that are present and entitled to vote at the Harrah's Special Meeting for purposes of determining whether a quorum exists, but abstentions will 11 have the same effect as votes against approval of the Stock Issuance Proposal. Brokers or nominees holding shares of record for customers generally will not be entitled to vote on the Stock Issuance Proposal unless they receive voting instructions from their customers. Because the Stock Issuance Proposal is the only matter for which specific approval is being solicited, any shares held by brokers or nominees for which no instructions are given by the beneficial owners thereof will not be voted, meaning that such shares will not count toward determining whether a quorum exists or be voted in any manner on the Stock Issuance Proposal. As of the record date for the Harrah's Special Meeting, directors and executive officers of Harrah's and their affiliates may be deemed to be beneficial owners of approximately 2.2% of the outstanding shares of Harrah's Common Stock and have expressed their intent to vote their shares in favor of the Stock Issuance Proposal. VOTING AND REVOCATION OF PROXIES All shares of Harrah's Common Stock which are entitled to vote and are represented at the Harrah's Special Meeting by properly executed proxies received prior to or at such meeting, and not revoked, will be voted at such meeting in accordance with the instructions indicated on such proxies. If no instructions are indicated such proxies will be voted for approval of the Stock Issuance Proposal. The Harrah's Board does not know of any matters other than those described in the notice of the Harrah's Special Meeting that are to come before such meeting. If any other matters are properly presented at the Harrah's Special Meeting for consideration, including, among other things, consideration of a motion to adjourn such meeting to another time and/or place (including, without limitation, for the purposes of soliciting additional proxies or allowing additional time for the satisfaction of conditions to the Merger), the persons named in the enclosed forms of proxy and acting thereunder generally will have discretion to vote on such matters in accordance with their best judgment. Notwithstanding the foregoing, proxies voting against a specific proposal may not be used by the persons named in the proxies to vote for adjournment of the meeting for the purpose of giving management additional time to solicit votes to approve such proposal. Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is voted. Proxies may be revoked by (i) filing with the Secretary of Harrah's, at or before the taking of the vote at the Harrah's Special Meeting, a written notice of revocation bearing a later date than the proxy, (ii) duly executing a later dated proxy relating to the same shares and delivering it to the Secretary of Harrah's before the taking of the vote at the Harrah's Special Meeting or (iii) attending the Harrah's Special Meeting and voting in person (although attendance at the Harrah's Special Meeting will not in and of itself constitute a revocation of a proxy). Any written notice of revocation or subsequent proxy should be sent to Harrah's Entertainment, Inc., 1023 Cherry Road, Memphis, Tennessee, 38117, Attention: Secretary, or hand delivered to the Secretary of Harrah's at or before the taking of the vote at the Harrah's Special Meeting. Stockholders that have instructed a broker to vote their shares must follow directions received from such broker in order to change their vote or to vote at the Harrah's Special Meeting. All expenses of Harrah's solicitation of proxies for the Harrah's Special Meeting will be borne by Harrah's. In addition to solicitation by use of the mails, proxies may be solicited from Harrah's stockholders by directors, officers and employees of Harrah's in person or by telephone, facsimile or other means of communication. Such directors, officers and employees will not be additionally compensated, but may be reimbursed for reasonable out-of-pocket expenses in connection with such solicitation. Harrah's has retained D.F. King & Co., Inc., a proxy solicitation firm, for assistance in connection with the solicitation of proxies for the Harrah's Special Meeting at a cost of approximately $9,000 plus reimbursement of reasonable out-of-pocket expenses. Arrangements will also be made with brokerage houses, custodians, nominees and fiduciaries for forwarding of proxy solicitation materials to beneficial owners of shares held of record by such brokerage houses, custodians, nominees and fiduciaries, and Harrah's will reimburse 12 such brokerage houses, custodians, nominees and fiduciaries for their reasonable expenses incurred in connection therewith. THE RIO SPECIAL MEETING GENERAL This Joint Proxy Statement/Prospectus is being furnished to stockholders of Rio as part of the solicitation of proxies by the Rio Board of Directors (the "Rio Board") for use at the Special Meeting of Stockholders of Rio (the "Rio Special Meeting") to be held on November 18, 1998 at 10:00 a.m., local time, at the Rio Suite Hotel & Casino, 3700 West Flamingo Road, Las Vegas, Nevada. This Joint Proxy Statement/Prospectus and the enclosed form of proxy are first being mailed to stockholders of Rio on or about October 20, 1998. The purpose of the Rio Special Meeting is: (a) to consider and vote upon a proposal to approve and adopt the Merger Agreement, pursuant to which, among other things, (i) the Merger will occur, with Rio continuing as the surviving corporation, and (ii) each outstanding share of Rio Common Stock, other than shares owned by Harrah's or by Rio as treasury stock (which will be cancelled), will be converted into the right to receive one share of Harrah's Common Stock (the "Merger Consideration"); and (b) to transact such other business as may properly come before the Rio Special Meeting or any adjournments or postponements thereof, including without limitation, potential adjournments or postponements of the Rio Special Meeting for the purpose of soliciting additional proxies in order to approve and adopt the Merger Agreement. Each copy of this Joint Proxy Statement/Prospectus mailed to holders of Rio Common Stock is accompanied by a form of proxy for use at the Rio Special Meeting. The Rio Board recommends that stockholders vote FOR the approval and adoption of the Merger Agreement. RECORD DATE AND VOTING Rio has fixed the close of business on October 5, 1998 as the record date for the determination of the Rio stockholders entitled to notice of and to vote at the Rio Special Meeting. Accordingly, only holders of record of Rio Common Stock on the record date will be entitled to notice of and to vote at the Rio Special Meeting. As of October 5, 1998, there were outstanding and entitled to vote 24,801,033 shares of Rio Common Stock (constituting all of the voting stock of Rio), which shares were held by approximately 1,263 holders of record. Each holder of record of shares of Rio Common Stock on the record date is entitled to one vote per share, which may be cast either in person or by properly executed proxy, at the Rio Special Meeting. The presence at the Rio Special Meeting, in person or by properly executed proxy, of the holders of a majority of the outstanding shares of Rio Common Stock is necessary to constitute a quorum at the Rio Special Meeting. The approval of the Merger Agreement will require the affirmative vote of the holders of a majority of the shares of Rio Common Stock outstanding on the record date. Shares of Rio Common Stock represented in person or by proxy will be counted for the purposes of determining whether a quorum is present at the Rio Special Meeting. Shares which abstain from voting as to the proposal to approve the Merger Agreement will be treated as shares that are present and entitled to vote at the Rio Special Meeting for purposes of determining whether a quorum exists, but abstentions will have the same effect as votes against approval of the Merger Agreement. Brokers or nominees holding shares of record for customers generally will not be entitled to vote on the proposal to approve the Merger Agreement unless they receive voting instructions from their customers. Because the approval of the Merger Agreement is the only matter for which specific approval is being solicited, any shares held by 13 brokers or nominees for which no instructions are given by the beneficial owners thereof will not be voted, meaning that such shares will have the same effect as shares voted against approval of the Merger Agreement. Holders of an aggregate of 4,107,706 shares of Rio Common Stock (the "Key Stockholders"), representing approximately 16.6% of the outstanding shares of Rio Common Stock as of the record date for the Rio Special Meeting, have each entered into a Stockholder Support Agreement (a "Stockholder Support Agreement," and collectively, the "Stockholder Support Agreements") with Harrah's pursuant to which such holders have agreed, among other things, to vote their shares of Rio Common Stock in favor of the Merger Agreement. See "The Merger Agreement--Stockholder Support Agreements." As of the record date for the Rio Special Meeting, directors and executive officers of Rio and their affiliates may be deemed to be beneficial owners of approximately 1% of the outstanding shares of Rio Common Stock (excluding shares covered by the Stockholder Support Agreements) and have expressed their intent to vote their shares in favor of the Merger Agreement. VOTING AND REVOCATION OF PROXIES All shares of Rio Common Stock which are entitled to vote and are represented at the Rio Special Meeting by properly executed proxies received prior to or at such meeting, and not revoked, will be voted at such meeting in accordance with the instructions indicated on such proxies. If no instructions are indicated, such proxies will be voted for approval of the Merger Agreement. The Rio Board does not know of any matters other than those described in the notice of the Rio Special Meeting that are to come before such meeting. If any other matters are properly presented at the Rio Special Meeting for consideration, including, among other things, consideration of a motion to adjourn such meeting to another time and/or place (including, without limitation, for the purposes of soliciting additional proxies or allowing additional time for the satisfaction of conditions to the Merger), the persons named in the enclosed forms of proxy and acting thereunder generally will have discretion to vote on such matters in accordance with their best judgment. Notwithstanding the foregoing, proxies voting against a specific proposal may not be used by the persons named in the proxies to vote for adjournment of the meeting for the purpose of giving management additional time to solicit votes to approve such proposal. Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is voted. Proxies may be revoked by (i) filing with the Secretary of Rio, at or before the taking of the vote at the Rio Special Meeting, a written notice of revocation bearing a later date than the proxy, (ii) duly executing a later dated proxy relating to the same shares and delivering it to the Secretary of Rio before the taking of the vote at the Rio Special Meeting or (iii) attending the Rio Special Meeting and voting in person (although attendance at the Rio Special Meeting will not in and of itself constitute a revocation of a proxy). Any written notice of revocation or subsequent proxy should be sent to Rio Hotel & Casino, Inc., 3700 West Flamingo Road, Las Vegas, Nevada, 89103, Attention: Secretary; or hand delivered to the Secretary of Rio at or before the taking of the vote at the Rio Special Meeting. Stockholders that have instructed a broker to vote their shares must follow directions received from such broker in order to change their vote or to vote at the Rio Special Meeting. All expenses of Rio's solicitation of proxies for the Rio Special Meeting will be borne by Rio. In addition to solicitation by use of the mails, proxies may be solicited from Rio stockholders by directors, officers and employees of Rio in person or by telephone, facsimile or other means of communication. Such directors, officers and employees will not be additionally compensated, but may be reimbursed for reasonable out-of-pocket expenses in connection with such solicitation. Rio has retained Innisfree M&A Incorporated, a proxy solicitation firm, for assistance in connection with the solicitation of proxies for the Rio Special Meeting at a cost of approximately $10,000 plus reimbursement of reasonable out-of-pocket expenses. Arrangements will also be made with brokerage houses, custodians, nominees and fiduciaries for 14 forwarding of proxy solicitation materials to beneficial owners of shares held of record by such brokerage houses, custodians, nominees and fiduciaries, and Rio will reimburse such brokerage houses, custodians, nominees and fiduciaries for their reasonable expenses incurred in connection therewith. STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXIES. RIO COMMON STOCK CERTIFICATES WILL BE EXCHANGED FOR SHARES OF HARRAH'S COMMON STOCK FOLLOWING CONSUMMATION OF THE MERGER IN ACCORDANCE WITH INSTRUCTIONS TO BE SENT TO HOLDERS OF RIO COMMON STOCK AFTER THE MERGER. THE MERGER BACKGROUND OF THE MERGER Rio has periodically reviewed its position in the gaming industry and its potential strategic alternatives. In its review, Rio has considered (i) the continued consolidation of the gaming industry, (ii) opportunities with respect to existing or planned operations, (iii) the competitive conditions of the Las Vegas market and potential opportunities to expand its operations into adjacent sites or new markets and (iv) the capital necessary to pursue expansion. During the last year, Rio and, since its retention on February 18, 1998 as Rio's financial advisor, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), were approached at various times about the possibility of pursuing a merger or other business combination. Rio retained Merrill Lynch to explore various strategic alternatives, including proposed business combinations involving Rio. Rio was approached by publicly held and private companies, including publicly traded real estate investment trusts and other companies in the gaming industry, including Harrah's. However, such contacts were preliminary or exploratory in nature and did not lead to substantive discussions or negotiations. In the spring of 1998, Rio and Harrah's separately had substantive discussions about investing in a start-up airline, now called National Airlines, Inc. ("National Airlines"), to be based in Las Vegas, Nevada. On June 2, 1998, in a meeting that took place in Las Vegas with certain representatives of National Airlines, James A. Barrett, Jr., President of Rio, and Colin V. Reed, Executive Vice President and Chief Financial Officer of Harrah's, discussed certain plans for each of their respective companies to enter into separate subscription agreements with National Airlines. Following that meeting, Messrs. Barrett and Reed met privately and discussed the possibility of a business combination involving Harrah's and Rio. Messrs. Barrett and Reed each agreed to speak with their respective chief executive officers to determine whether there was any interest in pursuing the matter. Rio and Harrah's both operate hotel-casinos in Las Vegas and compete with each other for hotel and casino customers. While Rio's marketing efforts have concentrated on Southern California and local Las Vegas customers, Harrah's marketing efforts have had a more national geographic focus. Following the discussions with their respective chief executive officers, Messrs. Barrett and Reed agreed that a meeting would be held on June 17, 1998, at Harrah's corporate headquarters in Memphis, Tennessee. Mr. Barrett met at that time with Philip G. Satre, Chairman of the Board, President and Chief Executive Officer of Harrah's, Mr. Reed, certain Harrah's executives and representatives of Harrah's financial advisor, BT Wolfensohn ("BT Wolfensohn"). During this meeting, the participants discussed their companies' respective corporate strategies and philosophies and other issues regarding a potential business combination of Harrah's and Rio. At the conclusion of the meeting, Mr. Barrett directed Merrill Lynch to begin analyzing on behalf of Rio a potential business combination with Harrah's. On June 18, 1998, Mr. Satre and Anthony A. Marnell II, Chairman of the Board and Chief Executive Officer of Rio, spoke via telephone to discuss the proposed business combination. That same day, Rio and Harrah's executed mutual confidentiality agreements, and, thereafter, began to exchange certain nonpublic information regarding each other. 15 On June 23, 1998, Messrs. Barrett and Reed met in New York City with representatives of BT Wolfensohn and Merrill Lynch for the purpose of commencing financial due diligence on the two companies. On June 25, 1998, the Rio Board held its regular monthly meeting. Mr. Barrett reported to the Rio Board the results of the preliminary meetings with the Harrah's representatives. The Rio Board acknowledged the discussions to date and directed management to continue discussions with Harrah's. On July 7, 1998, Messrs. Marnell and Barrett met in Memphis with Messrs. Satre and Reed. Also present during these meetings were representatives of Merrill Lynch and BT Wolfensohn. Additional information was exchanged during these meetings about company strategies, plans, potential synergies, analysis regarding the accretive nature of a potential business combination and other elements of a proposed transaction. During the course of the late June and early July 1998 meetings, the parties agreed that a stock for stock transaction was in the best interests of both companies due to the importance of maintaining Harrah's debt rating and Rio management's desire to have its stockholders share in the mutual benefits and opportunities created by combining the two companies. Following completion of the July 7, 1998 meeting, the Harrah's representatives proposed a per share valuation of Rio that would have resulted in an exchange ratio of less than one share of Harrah's Common Stock for each share of Rio Common Stock. On July 9, 1998, the Rio Board held a special telephonic meeting in which all Board members, except Mr. Marnell, participated. During this meeting, Mr. Barrett summarized the results of the preliminary meetings held to date with Harrah's representatives, the preliminary exchange of information between the companies and the preliminary suggestion made by Harrah's representatives about a proposed exchange ratio. Representatives of Merrill Lynch also participated and made a presentation to the Rio Board on a potential business combination of Harrah's and Rio. The Rio Board took no formal action at the July 9, 1998 meeting, but directed Rio's management to work toward obtaining a definitive agreement, including an exchange ratio of not less than one to one. Following the July 9, 1998 Rio Board meeting, Mr. Barrett communicated to Mr. Reed the Rio Board's directions regarding an acceptable exchange ratio, and, following consultation with each of the respective chief executive officers, the parties agreed to continue discussions. From July 10 through August 9, 1998, numerous meetings, telephone conversations and other communications were held between executives of Rio and Harrah's and their respective professional advisors to continue the exchange of detailed information, negotiate transaction documents and discuss various terms and conditions of a potential merger. On July 16 and 17, 1998, Mr. Barrett once again met with Mr. Reed and other Harrah's representatives in Memphis to explore various elements of a business combination transaction. On July 23, 1998, the Rio Board held its monthly meeting, and the Rio Board was provided with a report by management and counsel on the continuing results of merger negotiations, exchange of due diligence and other information relative to the progress of the transaction. Representatives of Merrill Lynch provided a preliminary presentation to the Rio Board regarding the respective valuations of Rio and Harrah's, an analysis of anticipated merger exchange ratios and other elements of the merger transaction. The Rio Board took no formal action at the July 23, 1998 meeting, but directed Rio's management to continue working toward obtaining a definitive agreement. On July 27, 1998, representatives of BT Wolfensohn met with representatives of Merrill Lynch and Mr. Barrett in Las Vegas to conduct financial due diligence and subsequently conducted further financial due diligence by conference call with Mr. Radcliffe, the Chief Financial Officer of Rio, on August 6, 1998. Representatives of Merrill Lynch met with members of Harrah's management and representatives of BT Wolfensohn in Memphis, Tennessee on July 23, 1998 to conduct similar financial due diligence and subsequently conducted further financial due diligence by conference call with members of Harrah's management and representatives of BT Wolfensohn on August 4, 1998. 16 On July 30, 1998, at a regularly scheduled Harrah's Board meeting, the Harrah's Board considered a possible merger transaction with Rio. At the meeting, Messrs. Satre and Reed made a presentation regarding the proposed transaction. BT Wolfensohn made a presentation to the Harrah's Board regarding certain financial aspects of the proposed merger. The Harrah's Board took no formal action at such meeting, but directed Harrah's management to continue working toward obtaining a definitive agreement. On July 31, 1998, and again on August 5, 1998, Mr. Barrett met in Memphis with Messrs. Satre and Reed and other representatives of Harrah's management to continue discussions on certain elements of the proposed merger transaction. On August 8, 1998, Messrs. Marnell and Barrett met with Messrs. Satre, Reed and certain other Harrah's management members, together with representatives of Rio's and Harrah's financial advisors, at Harrah's Las Vegas to discuss certain remaining business points relative to the proposed merger transaction and proceeded to negotiate the final terms and conditions of the Merger Agreement and to finalize other matters. On August 9, 1998, the Harrah's Board met telephonically (with two directors not participating due to scheduling conflicts) to consider the proposed Merger Agreement and related matters. At that meeting, certain members of management, representatives of Latham & Watkins (Harrah's legal counsel), Arthur Andersen LLP (Harrah's auditors) and BT Wolfensohn, made presentations to, and had discussions with, the Harrah's Board as to various aspects of the proposed transaction. The Harrah's Board reviewed and discussed the proposed transaction. BT Wolfensohn rendered its opinion that, as of such date, the exchange ratio of one share of Harrah's Common Stock for each share of Rio Common Stock ("Exchange Ratio") was fair, from a financial point of view, to Harrah's. The members of Harrah's Board present at such meeting voted unanimously to approve the Merger Agreement and the transactions contemplated thereby. Also, on August 9, 1998, the Rio Board met to consider the proposed Merger Agreement and related matters. At this meeting, certain members of management, representatives of Skadden, Arps, Slate, Meagher & Flom LLP, Kummer Kaempfer Bonner & Renshaw (Rio's legal co-counsel) and Merrill Lynch, made presentations to, and had discussions with, the Rio Board as to various aspects of the proposed transaction. The Rio Board reviewed and discussed the proposed transaction. Merrill Lynch rendered its opinion that, as of such date, the Exchange Ratio was fair to Rio's stockholders from a financial point of view. Following these presentations and discussions, the members of the Rio Board who were not executive officers of Rio discussed the proposed transaction with Rio's legal and financial advisers. The Rio Board voted unanimously to approve the Merger Agreement and the transactions contemplated thereby. Following the approval of the Merger by the Rio Board and the Harrah's Board, Rio and Harrah's executed the Merger Agreement. On the morning of August 10, 1998, Rio and Harrah's issued a joint press release announcing the execution of the Merger Agreement. The Merger Agreement entered into on August 9, 1998 contained a condition to Harrah's obligation to consummate the Merger that Harrah's receive an opinion from Arthur Andersen LLP regarding the appropriateness of accounting for the Merger as a "pooling of interests." As a condition for pooling of interests accounting, Harrah's would be required to reissue a portion of its common shares that it had acquired as treasury stock during the previous two years. In the three weeks following the date of the Merger Agreement, representatives of both Harrah's and Rio, together with their respective accountants, and financial and legal advisors, determined that it would be preferable, for financial and operational reasons, to account for the Merger as a "purchase." By utilizing purchase accounting, (i) Harrah's would avoid having to reissue shares of its common stock prior to consummating the Merger possibly during a period of declining market prices, (ii) Harrah's would not be precluded following the Merger from engaging in certain corporate transactions (such as share repurchases, assets sales and reorganizations) which are inconsistent with pooling of interests accounting, and (iii) Harrah's and Rio would have greater flexibility with respect to their executive compensation and employee benefit arrangements. 17 On September 3, 1998, the Rio Board, and on September 4, 1998, the Harrah's Board, in telephonic meetings, considered presentations by each company's respective management and outside financial and legal advisors regarding the possibility of accounting for the Merger as a purchase. The Harrah's Board also considered an oral presentation by its outside accountants regarding the possibility of accounting for the Merger as a purchase. Harrah's and Rio's financial advisors each confirmed that the change from pooling to purchase accounting did not affect their opinion to their respective clients and that, as of August 9, 1998, the Exchange Ratio was fair, from a financial point of view, to Harrah's or Rio and its stockholders, as the case may be. The Boards of Directors of Harrah's and Rio each authorized its management to take further action to cause the Merger to be accounted for as a purchase. On September 4, 1998, Harrah's and Rio formally amended the Merger Agreement to eliminate the "pooling condition" and to revise other provisions that were inconsistent with using purchase accounting. RECOMMENDATIONS OF THE BOARDS OF DIRECTORS OF HARRAH'S AND RIO; REASONS FOR THE MERGER HARRAH'S. The Harrah's Board believes that the terms of the Merger are fair to and in the best interests of Harrah's and its stockholders. Accordingly, the Harrah's Board has approved and adopted the Merger Agreement and the transactions contemplated thereby and recommends approval of the Stock Issuance Proposal by the stockholders of Harrah's. In reaching its determination to approve the Merger Agreement and recommend approval of the Stock Issuance Proposal to Harrah's stockholders, the Harrah's Board considered the information presented to it by Harrah's management, as well as Harrah's professional advisors, and weighed the positive and countervailing factors associated with the transaction. The factors considered by the Harrah's Board included, without limitation: - OPPORTUNITY TO ACQUIRE A PROFITABLE, PREMIER LAS VEGAS PROPERTY AND BRAND. The Harrah's Board considered that the Merger will enable Harrah's to add a profitable, premier Las Vegas destination resort with a unique level of service, strong brand name, and distinct customer base to Harrah's existing national distribution of casino offerings. The Harrah's Board took into account the fact that the Rio Suite Hotel & Casino is widely recognized as one of the leading hotel and casino properties in Las Vegas, providing more hotel and casino resort amenities, and a wider selection of quality restaurants and other entertainment options, than Harrah's Las Vegas. The Harrah's Board viewed favorably the opportunity to acquire a property in Las Vegas that caters to a customer base that is younger and more affluent, as well as more geographically concentrated in California and local vicinities in and around Las Vegas, than the customer base currently served by Harrah's Las Vegas, and which would give Harrah's an additional distinct product in Las Vegas to offer to its national customer base. Another consideration was the fact that Rio owns 35 undeveloped acres adjacent to its facility which would provide future growth opportunities for Harrah's. Harrah's currently owns no undeveloped land in Las Vegas and its current facility cannot be expanded. The Harrah's Board also took into account the potential benefits of utilizing Rio's brand name and product and service offerings at other existing and future Harrah's properties. - OPPORTUNITIES FOR EFFICIENCIES AND SYNERGIES. The Harrah's Board considered that Harrah's, together with Rio, is expected to increase its profitability through cost savings and operating efficiencies resulting from the elimination of certain redundant functions which would exist in the combined company such as functions associated with operating as a single public company, as well as other functions that can be integrated into Harrah's centralized system (e.g., financial reporting, treasury/cash management, certain human resources, purchasing and risk management services). Harrah's management advised the Harrah's Board that a review of Rio's current cost structure indicated that the amount of such savings and efficiencies to the combined company is estimated to be approximately $7.0 million per year. The Harrah's Board also considered the possibility that Harrah's acquisition of Rio will enable Harrah's to increase revenues at both Rio's and Harrah's Las Vegas 18 properties and at Harrah's other properties through increased cross-visitation and national cross-marketing. - FINANCING COST SAVINGS. The Harrah's Board also considered annual cost savings attributable to reductions in financing costs that it expects will result from the Merger due primarily to Harrah's lower cost of borrowing. It also took into account the uncertainties and risks associated with achieving such potential savings. - FINANCIAL CONSIDERATIONS. The Harrah's Board considered its evaluation of the financial terms of the Merger and their effect on holders of Harrah's Common Stock. The Harrah's Board considered the financial performance and condition, business and prospects of the two companies, including the respective earnings history and performance of each of the two companies, as well as the results of Harrah's due diligence review of Rio. Among such financial considerations, the Harrah's Board reviewed the respective recent and historical stock prices of Harrah's and Rio, and noted that, based on the closing stock prices for Harrah's Common Stock and Rio Common Stock on and for the one month ended July 24, 1998, the Exchange Ratio represented a premium of 5.6% and 20%, respectively, over the market price for Rio Common Stock. (On August 6, two trading days prior to public announcement of the Merger, the Exchange Ratio represented a premium of 18% over the market price for Rio Common Stock; stockholders are advised to obtain current market quotations prior to voting on the Stock Issuance Proposal.) The Harrah's Board also took into account the detailed financial analyses and pro forma and other information with respect to the Merger prepared by Harrah's and Rio management and presented by Harrah's financial advisor, including the projected effects on earnings per share and cash flow. The Harrah's Board also considered the effect of the Merger on ratios of Harrah's debt to capital, cash flow to interest expense and debt to cash flow. - OPINION OF BT WOLFENSOHN. The Harrah's Board considered the presentations of BT Wolfensohn on July 30, 1998, August 9, 1998 and September 4, 1998, and written opinion delivered by BT Wolfensohn as of August 9, 1998 that as of such date, the Exchange Ratio was fair, from a financial point of view, to Harrah's. See"--Opinion of Financial Advisor to Harrah's." A copy of BT Wolfensohn's written opinion, which sets forth the assumptions made, matters considered and limitation on the review undertaken is attached as Annex B to this Joint Proxy Statement/Prospectus and is incorporated herein by reference. - COMPLEMENTARY NATURE OF BUSINESSES AND CULTURE. The Harrah's Board considered the complementary nature of Rio's operations and management culture with that of Harrah's. Specifically, the Board considered that the service orientation of Rio's operations, its high level of customer satisfaction, its focus on developing strong brand identity and its strong emphasis on employee relations would complement Harrah's pursuit of the same goals. The Harrah's Board also discussed the likelihood that Rio's innovative and dynamic management culture would integrate well with a similar management culture at Harrah's. - STRUCTURE OF THE MERGER; TERMS OF THE MERGER AGREEMENT. The Harrah's Board considered the terms of the Merger Agreement and its legal and tax implications. The Harrah's Board considered the size of the termination fee payable, in certain circumstances, by either party under the Merger Agreement and also considered the Stockholder Support Agreements and the Exchange Ratio. As indicated above, the Harrah's Board initially considered that the Merger was expected to be accounted for as a pooling of interests transaction, but subsequently agreed that the Merger should be accounted for as a purchase. The Harrah's Board also considered that the Merger generally is not expected to result in federal income taxes. The Harrah's Board considered the fact that the Exchange Ratio is a fixed number and will not be adjusted in the event that there are any increases or decreases in the price of either Harrah's Common Stock or Rio Common Stock. - COUNTERVAILING CONSIDERATIONS. The Board of Directors of Harrah's considered certain factors which may be characterized as countervailing considerations, including: 19 - The risks of increasing Harrah's presence in the increasingly competitive Las Vegas market in light of both the recent and planned expansion of existing and new casinos and hotels in Las Vegas and the possible passage of ballot initiatives in California that could result in increased competition from Indian gaming. - The possibility that combining the businesses of Harrah's and Rio may prove more difficult than expected in terms of integrating different operational systems, the Rio brand name and marketing strategy and the Rio employee base into the Harrah's network of hotels and casinos. - The risk that Harrah's management may not be as successful as Rio's management at operating a casino targeted at a customer base that is younger, more affluent and more concentrated in a different geographic region than the customer base currently served by Harrah's Las Vegas. The foregoing discussion of the information and factors considered and given weight by the Harrah's Board includes all material factors considered by the Harrah's Board. In reaching the determination to approve the Merger Agreement and recommend approval of the Stock Issuance Proposal, the Harrah's Board concluded that the potential benefits of the Merger outweighed the potential risks, but did not assign any relative or specific weights to the foregoing factors, and individual directors may have given differing weights to the different factors. The Harrah's Board did not attempt to analyze the fairness of the Exchange Ratio in isolation from the considerations as to the businesses of Harrah's and Rio, the strategic merits of the Merger or the other considerations referred to above. The Harrah's Board did, however, take into account, and placed reliance upon, the analyses performed by, and the opinion rendered by, BT Wolfensohn as to the fairness, from a financial point of view, of the Exchange Ratio to Harrah's. THE HARRAH'S BOARD HAS APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY AND BELIEVES THAT THE TERMS OF THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, HARRAH'S AND ITS STOCKHOLDERS. THE HARRAH'S BOARD RECOMMENDS A VOTE FOR APPROVAL OF THE STOCK ISSUANCE PROPOSAL. RIO. The Rio Board believes that the terms of the Merger are fair to and in the best interests of Rio and its stockholders. Accordingly, the Rio Board has unanimously approved and adopted the Merger Agreement and the transactions contemplated thereby and recommends approval and adoption of the Merger Agreement by the stockholders of Rio. In reaching its determination to approve the Merger Agreement and recommend approval of the Merger Agreement to Rio's stockholders, the Rio Board considered the information presented to it by Rio's management, as well as Rio's professional advisors, and weighed the positive and countervailing factors associated with the transaction. The factors considered by the Rio Board included, without limitation: - OPPORTUNITIES FOR SYNERGIES AND EFFICIENCIES. The Rio Board considered that the combination of Rio and Harrah's will potentially increase profitability through various revenue synergies and cost savings. The Rio Board considered the potential benefits and risks to increasing revenues by maintaining Rio as a separate upscale resort brand in Las Vegas and possibly other jurisdictions, and then cross-marketing the Harrah's and Rio brands, including by consolidating Rio's operations under Harrah's marketing, reservation and database systems. The Rio Board also took into account the anticipated cost savings that will result from Harrah's lower cost of borrowing and the elimination of certain duplicative corporate overhead. - OPPORTUNITY TO DIVERSIFY OPERATIONS. The Rio Board considered that the Merger will provide Rio's stockholders with a geographically diversified portfolio of gaming operations to balance the risks of 100% exposure to the Las Vegas gaming market. 20 - OPPORTUNITY TO DIVERSIFY INVESTMENT. The Rio Board considered the anticipated benefits to Rio's stockholders of holding shares in a larger capitalized and diversified gaming company that typically trades at higher earnings multiples than the range in which Rio Common Stock has traditionally traded. - FINANCIAL AND OTHER CONSIDERATIONS. The Rio Board considered its evaluation of the financial terms of the Merger and their effect on holder's of Rio Common Stock. The Rio Board considered the financial condition, results of operations, business and prospects of Rio and Harrah's, including the competitive nature of the Las Vegas market in which Rio operates and its position in such market. The Rio Board also considered the historical market prices and trading information of Rio and Harrah's, and that (i) the closing price of Harrah's Common Stock on the New York Stock Exchange (the "NYSE") on August 7, 1998 (the "Last Trading Day"), the last trading day prior to the public announcement of the execution of the Merger Agreement, was $20.125, which represents a premium of approximately 6.6% over the $18.875 per share closing price of Rio Common Stock on the NYSE on the Last Trading Day, and (ii) the average closing price of Harrah's Common Stock on the NYSE for the three-month period ended on the Last Trading Day was $22.88 per share, which represents a premium of approximately 16.0% over the $19.73 per share average closing price of Rio Common Stock on the NYSE for the same three-month period. The Rio Board also took into account the presentations and analyses by its management, financial advisor and outside legal counsel regarding the business, financial and accounting aspects, and the results of due diligence, with respect to the Merger. - OPINION OF MERRILL LYNCH. The Rio Board considered the presentations delivered by Merrill Lynch on August 9, 1998 and September 3, 1998 and Merril Lynch's written opinion dated as of August 9, 1998, to the effect that, as of the date of such opinion, the Exchange Ratio is fair, from a financial point of view, to the holders of Rio Common Stock (other than Harrah's and its affiliates). See "--Opinion of Financial Advisor to Rio." A copy of Merrill Lynch's written opinion dated as of August 9, 1998, which sets forth the assumptions made, matters considered and limitations on the review undertaken, is attached as Annex C to this Joint Proxy Statement/Prospectus and is incorporated herein by reference. - TERMS AND STRUCTURE OF THE MERGER. The Rio Board considered the terms and structure of the Merger and its legal and tax implications. The Rio Board considered that the Merger is expected to be accounted for as a purchase transaction and is generally not expected to result in federal income taxes to Rio or its stockholders. The Rio Board considered the fact that the Exchange Ratio is fixed and will not be adjusted in the event that there are any increases or decreases in the price of either Rio Common Stock or Harrah's Common Stock. The Rio Board also considered the amount of the termination fee payable by Rio or Harrah's to the other party under certain circumstances if the Merger were not consummated. - COUNTERVAILING CONSIDERATIONS. The Rio Board considered the following countervailing considerations with respect to the Merger: the business and financial risks associated with Harrah's financial obligations to the Harrah's Jazz project in New Orleans; the concerns about the ability of Harrah's to assimilate Rio into its operations so soon after Harrah's acquisition of Showboat; the ability of Harrah's to successfully maintain and market the separate Rio brand; the potential negative impacts on Rio employee relations as a result of being made part of a larger corporation with a much greater number of employees; and the recent regulatory issues arising in certain of Harrah's riverboat locations in Missouri. - INTERESTS OF CERTAIN PERSONS IN THE MERGER. The Rio Board considered the fact that certain of its members and members of Rio's management have interests in the Merger that are in addition to, and not necessarily aligned with, the interests of holders of Rio Common Stock. See "--Interests of Certain Persons in the Merger." The foregoing discussion of the information and factors considered by the Rio Board is not meant to be exhaustive but includes all material factors considered by the Rio Board. The Rio Board did not quantify or attach any particular weight to the various factors that it considered in reaching its determination that the Merger Agreement and the Merger are fair to and in the best interests of Rio and its stockholders. As a result of its consideration of the foregoing, the Rio Board determined that the Merger Agreement and the Merger are fair to and in the best interests of Rio and its stockholders and approved 21 and adopted the Merger Agreement. In considering the recommendation of the Rio Board with respect to the Merger, Rio's stockholders should be aware that the interests of certain directors and executive officers with respect to the Merger are or may be different from or in addition to the interests of the stockholders generally. The Rio Board was aware of these interests, and took these interests into account in approving the Merger Agreement and the transactions contemplated thereby. See "--Interests of Certain Persons in the Merger." ACCORDINGLY, THE RIO BOARD RECOMMENDS THAT ITS STOCKHOLDERS VOTE "FOR" APPROVAL AND ADOPTION OF THE MERGER AGREEMENT. OPINION OF FINANCIAL ADVISOR TO HARRAH'S BT Wolfensohn has acted as financial advisor to Harrah's in connection with the Merger. At the August 9, 1998 meeting of the Harrah's Board, BT Wolfensohn delivered its written opinion, dated as of such date, to the Harrah's Board to the effect that, as of the date of such opinion, based upon and subject to the assumptions made, matters considered and limits of the review undertaken by BT Wolfensohn, the Exchange Ratio was fair, from a financial point of view, to Harrah's. THE FULL TEXT OF BT WOLFENSOHN'S WRITTEN OPINION, DATED AUGUST 9, 1998 (THE "BT WOLFENSOHN OPINION"), WHICH SETS FORTH, AMONG OTHER THINGS, THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS ON THE REVIEW UNDERTAKEN BY BT WOLFENSOHN IN CONNECTION WITH THE BT WOLFENSOHN OPINION, IS ATTACHED AS ANNEX B TO THIS JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. HARRAH'S STOCKHOLDERS ARE URGED TO READ THE BT WOLFENSOHN OPINION IN ITS ENTIRETY. THE SUMMARY OF THE BT WOLFENSOHN OPINION SET FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE BT WOLFENSOHN OPINION. In connection with BT Wolfensohn's role as financial advisor to Harrah's, and in arriving at its opinion, BT Wolfensohn has, among other things, reviewed certain publicly available financial information and other information concerning Harrah's and Rio and certain internal analyses and other information furnished to it by Harrah's and Rio. BT Wolfensohn also held discussions with the members of the senior managements of Harrah's and Rio regarding the businesses and prospects of their respective companies and the joint prospects of a combined enterprise. In addition, BT Wolfensohn (i) reviewed the reported prices and trading activity for the common stock of both Harrah's and Rio, (ii) compared certain financial and stock market information for Harrah's and Rio with similar information for selected companies whose securities are publicly traded, (iii) reviewed the financial terms of selected recent business combinations which it deemed comparable in whole or in part, (iv) reviewed the terms of the Merger Agreement, and (v) performed such other studies and analyses and considered such other factors as it deemed appropriate. In preparing its opinion, BT Wolfensohn did not assume responsibility for the independent verification of, and did not independently verify, any information, whether publicly available or furnished to it, concerning Harrah's or Rio, including, without limitation, any financial information, forecasts or projections, considered in connection with the rendering of its opinion. Accordingly, for purposes of its opinion, BT Wolfensohn assumed and relied upon the accuracy and completeness of all such information. BT Wolfensohn did not conduct a physical inspection of any of the properties or assets, and did not prepare or obtain any independent evaluation or appraisal of any of the assets or liabilities of Harrah's or Rio. With respect to the financial forecasts and projections made available to BT Wolfensohn and used in its analysis, including analyses and forecasts of certain cost savings, operating efficiencies, revenue effects and financial synergies (collectively, the "Synergies") expected by Harrah's and Rio to be achieved as a result of the Merger, BT Wolfensohn has assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of Harrah's or Rio as to the matters covered thereby. In rendering its opinion, BT Wolfensohn expressed no view as to the reasonableness of such forecasts and projections, including the Synergies, or the assumptions on which they are based. The BT Wolfensohn Opinion was necessarily based upon economic, market and other conditions as in effect on, and the information made available to BT Wolfensohn as of, the date of such opinion. 22 For purposes of rendering its opinion, BT Wolfensohn has assumed that, in all respects material to its analysis, the representations and warranties of Harrah's and Rio contained in the Merger Agreement are true and correct, that Harrah's and Rio will each perform all of the covenants and agreements to be performed by it under the Merger Agreement and all conditions to the obligation of each of Harrah's and Rio to consummate the Merger will be satisfied without any waiver thereof. BT Wolfensohn has also assumed that all material governmental, regulatory or other approvals and consents required in connection with the consummation of the transactions contemplated by the Merger Agreement will be obtained and that in connection with obtaining any necessary governmental, regulatory or other approvals and consents, or any amendments, modifications or waivers to any agreements, instruments or orders to which either Harrah's or Rio is a party or subject or by which it is bound, no limitations, restrictions or conditions will be imposed or amendments, modifications or waivers made that would have a material adverse effect on Harrah's or Rio or materially reduce the contemplated benefits of the Merger to Harrah's. In addition, BT Wolfensohn has been advised by Harrah's, and accordingly has assumed for purposes of its opinion, that the Merger will be tax-free to Harrah's. Set forth below is a brief summary of certain financial analyses performed by BT Wolfensohn in connection with its opinion and reviewed with the Harrah's Board at its meetings on July 30, 1998, August 9, 1998 and September 4, 1998. ANALYSIS OF SELECTED PUBLICLY TRADED COMPANIES. BT Wolfensohn compared certain financial information and commonly used valuation measurements for Rio and Harrah's to corresponding information and measurements for a group of publicly traded gaming companies (consisting of Circus Circus Enterprises, Inc., Hilton Hotels Corporation, MGM Grand, Inc., Mirage Resorts Inc. and Primadonna Resorts, Inc. (collectively, the "Selected Companies")). Such financial information and valuation measurements included, among other things, (i) common equity market valuation based on closing stock prices as of July 24, 1998; (ii) ratios of common equity market value as adjusted for debt and cash ("Enterprise Value") to earnings before interest expense, income taxes and depreciation and amortization ("EBITDA"); and (iii) ratios of common equity market prices per share ("Equity Value") to earnings per share ("EPS"). To calculate the trading multiples for Rio, Harrah's and the Selected Companies, BT Wolfensohn used publicly available information concerning historical and projected financial performance, including published historical financial information and earnings estimates reported by the Institutional Brokers Estimate System ("IBES"). IBES is a data service that monitors and publishes compilations of earnings estimates by selected research analysts regarding companies of interest to institutional investors. BT Wolfensohn calculated that, on a forward calendar year 1998 and 1999 basis, the multiple of Enterprise Value to EBITDA was 7.6x and 5.5x for Rio and 7.7x and 6.4x for Harrah's, compared to a range of 6.0x to 12.0x and 6.3x to 7.1x, with a median of 7.9x and 6.7x, for the Selected Companies. BT Wolfensohn further calculated that the multiple of Equity Value to estimated calendar year 1998 EPS was 16.3x for Rio and 15.0x for Harrah's, compared to a range of 15.3x to 22.9x, with a median of 18.3x, for the Selected Companies; and the multiple of Equity Value to estimated calendar year 1999 EPS was 12.1x for Rio and 12.7x for Harrah's, compared to a range of 13.8x to 17.5x, with a median of 14.2x, for the Selected Companies. BT Wolfensohn also calculated the implied transaction multiples for Rio at the $20.19 share price of Harrah's Common Stock as of July 24, 1998. On a forward calendar year 1998 and 1999 basis, the multiple of Enterprise Value to EBITDA, assuming no cost savings, was 7.8x and 5.7x, respectively; and the multiple of Equity Value to estimated calendar year 1998 and 1999 EPS, assuming no cost savings, was 17.3x and 12.8x, respectively. None of the companies utilized as a comparison is identical to Rio or Harrah's. Accordingly, BT Wolfensohn believes the analysis of publicly traded comparable companies is not simply mathematical. Rather, it involves complex considerations and qualitative judgments, reflected in the BT Wolfensohn Opinion, concerning differences in financial and operating characteristics of the comparable companies and other factors that could affect the public trading value of the comparable companies. 23 ANALYSIS OF SELECTED PRECEDENT TRANSACTIONS. BT Wolfensohn reviewed the financial terms, to the extent publicly available, of six proposed, pending or completed mergers and acquisition transactions since December 1994 involving companies in the gaming industry (the "Selected Transactions"). BT Wolfensohn calculated various premiums over market value based on certain publicly available information for each of the Selected Transactions and compared them to corresponding premiums over market value for the Merger, based on the Exchange Ratio. The transactions reviewed were (Acquiror/Target (Date Announced)): Colony Capital/Harvey's Resorts (February 1998), Crescent/Station Casinos (January 1998), Harrah's/Showboat (December 1997), Sun International/Griffin Gaming (August 1996), Hilton/Bally Entertainment (June 1996) and ITT/Caesars World (December 1994). BT Wolfensohn calculated that the Selected Transactions were effected at a premium to the acquired companies' per share market price prior to the announcement of the transaction ranging from 24.8% to 88.9%, with a median of 69.0%, compared to a premium of 18.0%, for the Merger (based on the per share market price two trading days prior to the August 10, 1998 announcement of the proposed Merger). All multiples for the Selected Transactions were based on public information available at the time of announcement of such transaction, without taking into account differing market and other conditions during the two-year period during which the Selected Transactions occurred. Because the reasons for, and circumstances surrounding, each of the precedent transactions analyzed were so diverse, and due to the inherent differences between the operations and financial conditions of Rio and Harrah's and the companies involved in the Selected Transactions, BT Wolfensohn believes that a comparable transaction analysis is not simply mathematical. Rather, it involves complex considerations and qualitative judgments, reflected in the BT Wolfensohn Opinion, concerning differences between the characteristics of these transactions and the Merger that could affect the value of the subject companies and businesses and Rio and Harrah's. HISTORICAL EXCHANGE RATIO ANALYSIS. BT Wolfensohn reviewed the historical ratio of the daily per share market closing prices of Rio Common Stock divided by the corresponding prices of Harrah's Common Stock over the one-year, three-month and one-month periods prior to July 24, 1998 and as of July 24, 1998. The average exchange ratios for these time periods and as of such date were 1.014, 0.859, 0.801 and 0.947, respectively. BT Wolfensohn also calculated the premium implied by the Exchange Ratio over the market price of Rio Common Stock on July 24, 1998, which at the market price of $20.19 per share of Harrah's Common Stock on the same day was 5.6%. DISCOUNTED CASH FLOW ANALYSIS. BT Wolfensohn performed a discounted cash flow analysis for both Rio and Harrah's. BT Wolfensohn calculated the discounted cash flow values for each of Rio and Harrah's as the sum of the net present values of (i) the estimated future cash flow that Rio or Harrah's, as the case may be, will generate for the years 1999 through 2002, plus (ii) the value of Rio or Harrah's at the end of such period. The estimated future cash flows for Rio were based on the financial projections for Rio for the years 1999 through 2000 prepared by Rio management and for 2001 and 2002 using BT Wolfensohn estimates. The estimated future cash flows for Harrah's were based on financial projections for Harrah's for the years 1999 through 2002 prepared by Harrah's management. The terminal values of Rio and Harrah's were calculated based on projected EBITDA for 2002 and a range of multiples of 6.0x to 8.0x. BT Wolfensohn used discount rates ranging from 10% to 14%. BT Wolfensohn used such discount rates based on its judgment of the estimated weighted average cost of capital of Rio and Harrah's, and used such multiples based on its review of the trading characteristics of the common stock of the Selected Companies. This analysis indicated a range of values for Rio Common Stock of $22.45 to $29.83 per share, for Harrah's Common Stock of $19.81 to $28.89 per share and for Harrah's Common Stock, pro forma for the Merger, of $19.70 to $28.58 per share, assuming no cost savings. PRO FORMA COMBINED EARNINGS ANALYSIS. BT Wolfensohn analyzed certain pro forma effects of the Merger. Based on such analysis, BT Wolfensohn computed the resulting dilution/accretion to the combined company's EPS estimate for the fiscal years ending 1999, 2000 and 2001, before and after taking into 24 account any potential cost savings and other synergies identified by management that Rio and Harrah's could achieve if the Merger were consummated and before non-recurring costs relating to the Merger. BT Wolfensohn noted that before taking into account any potential cost savings and other synergies other than potential financial savings and before such non-recurring costs, the Merger would be modestly accretive in fiscal 1999 and essentially break-even in fiscal years 2000 and 2001. BT Wolfensohn also noted that after taking into account the potential cost savings and other synergies for the fiscal years ending 1999, 2000 and 2001, respectively, and before such non-recurring costs, the Merger would be accretive to the combined company's EPS for the fiscal years ending 1999, 2000 and 2001. The foregoing summary describes all analyses and factors that BT Wolfensohn deemed material in its presentation to Harrah's Board, but is not a comprehensive description of all analyses performed and factors considered by BT Wolfensohn in connection with preparing its opinion. The preparation of a fairness opinion is a complex process involving the application of subjective business judgment in determining the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, is not readily susceptible to summary description. BT Wolfensohn believes that its analyses must be considered as a whole and that considering any portion of such analyses and of the factors considered without considering all analyses and factors could create a misleading view of the process underlying the opinion. In arriving at its fairness determination, BT Wolfensohn did not assign specific weights to any particular analyses. In conducting its analyses and arriving at its opinions, BT Wolfensohn utilized a variety of generally accepted valuation methods. The analyses were prepared solely for the purpose of enabling BT Wolfensohn to provide its opinion to the Harrah's Board as to the fairness to Harrah's of the Exchange Ratio and does not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold, which are inherently subject to uncertainty. In connection with its analyses, BT Wolfensohn made, and was provided by Harrah's management with, numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond Harrah's or Rio's control. Analyses based on estimates or forecasts of future results are not necessarily indicative of actual past or future values or results, which may be significantly more or less favorable than suggested by such analyses. Because such analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of Harrah's, Rio or their respective advisors, neither Harrah's nor BT Wolfensohn nor any other person assumes responsibility if future results or actual values are materially different from these forecasts or assumptions. The terms of the Merger were determined through negotiations between Harrah's and Rio and were approved by the Harrah's Board. Although BT Wolfensohn provided advice to Harrah's during the course of these negotiations, the decision to enter into the Merger was solely that of the Harrah's Board. As described above, the opinion and presentation of BT Wolfensohn to the Harrah's Board were only one of a number of factors taken into consideration by the Harrah's Board in making its determination to approve the Transaction. The BT Wolfensohn Opinion was provided to the Harrah's Board to assist it in connection with its consideration of the Merger and does not constitute a recommendation to any holder of Harrah's Common Stock as to how to vote with respect to the Merger. Harrah's selected BT Wolfensohn as financial advisor in connection with the Merger based on BT Wolfensohn's qualifications, expertise, reputation and experience in mergers and acquisitions. BT Wolfensohn is engaged in the merger and acquisition and client advisory business and, for legal and regulatory purposes, is a division of BT Alex. Brown Incorporated, a registered broker dealer and member of the NYSE. Harrah's retained BT Wolfensohn pursuant to a letter agreement dated June 9, 1998 (the "Engagement Letter"), which superseded an initial engagement letter dated May 14, 1997. As compensation for BT Wolfensohn's services in connection with the Merger, Harrah's previously paid BT Wolfensohn $250,000 at the time of its initial engagement, paid BT Wolfensohn an additional cash fee of $750,000 upon Harrah's entering into the Merger Agreement and has agreed to pay an additional cash fee of $3.75 million if the Merger is consummated. Regardless of whether the Merger is consummated, Harrah's has agreed to 25 reimburse BT Wolfensohn for reasonable fees and disbursements of BT Wolfensohn's counsel and all of BT Wolfensohn's reasonable travel and other out-of-pocket expenses incurred in connection with the Merger or otherwise arising out of the retention of BT Wolfensohn under the Engagement Letter. Harrah's has also agreed to indemnify BT Wolfensohn and certain related persons to the full extent lawful against certain liabilities, including certain liabilities under the federal securities laws arising out of its engagement or the Merger. An affiliate of BT Wolfensohn acts as the administrative agent on a $2.1 billion revolving credit facility to Harrah's and will be acting as the administrative agent on a $236.5 million credit facility for Jazz Casino Company, which will be the owner and operator of the New Orleans land-based casino if a reorganization plan of Harrah's Jazz Company is consummated. BT Wolfensohn and its affiliates may actively trade securities of Harrah's or Rio for their own account or the account of their customers and, accordingly, may from time to time hold a long or short position in such securities. OPINION OF FINANCIAL ADVISOR TO RIO On February 18, 1998, Rio retained Merrill Lynch to act as its exclusive financial advisor in connection with the exploration of various strategic alternatives available to Rio. In connection with such engagement, Rio requested that Merrill Lynch evaluate the fairness of the Exchange Ratio to the holders of Rio Common Stock (other than Harrah's and its affiliates) from a financial point of view. On August 9, 1998, Merrill Lynch delivered its opinion to the Rio Board, which opinion was subsequently confirmed in a written opinion, dated August 9, 1998, to the effect that, as of such date and based upon the assumptions made, matters considered and limits of review, as set forth in such opinion, the proposed Exchange Ratio was fair from a financial point of view to the holders of Rio Common Stock, other than Harrah's and its affiliates. In its August 9, 1998 opinion, Merrill Lynch assumed, with the permission of the Rio Board, that the Merger would be accounted for as a pooling of interests under U.S. generally accepted accounting principles ("GAAP"). On September 3, 1998, Merrill Lynch redelivered its written opinion to the Rio Board dated as of August 9, 1998 (the "Merrill Lynch Opinion") to the effect that, as of such date and based upon the assumptions made, matters considered and limits of review, as set forth in such opinion, the proposed Exchange Ratio was fair from a financial point of view to the holders of Rio Common Stock, other than Harrah's and its affiliates. The Merrill Lynch Opinion assumed, with the permission of the Rio Board, that the Merger would be accounted for as a purchase under GAAP. A COPY OF THE MERRILL LYNCH OPINION, WHICH SETS FORTH THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND CERTAIN LIMITATIONS ON THE SCOPE OF REVIEW UNDERTAKEN BY MERRILL LYNCH, IS ATTACHED HERETO AS ANNEX C AND IS INCORPORATED HEREIN BY REFERENCE. THE DESCRIPTION OF THE WRITTEN OPINION SET FORTH HEREIN IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE WRITTEN OPINION. STOCKHOLDERS OF RIO ARE URGED TO READ SUCH OPINION IN ITS ENTIRETY. THE MERRILL LYNCH OPINION IS ADDRESSED TO THE RIO BOARD AND ADDRESSES ONLY THE FAIRNESS FROM A FINANCIAL POINT OF VIEW OF THE EXCHANGE RATIO AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY RIO STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE OR OTHERWISE ACT IN RESPECT OF THE MERGER. THE EXCHANGE RATIO WAS DETERMINED ON THE BASIS OF NEGOTIATIONS BETWEEN RIO AND HARRAH'S AND WAS APPROVED BY THE RIO BOARD. In connection with the preparation of the Merrill Lynch Opinion, Merrill Lynch, among other things: (i) reviewed Rio's Annual Report to Stockholders and Rio's Annual Report on Form 10-K and related financial information for the fiscal year ended December 31, 1997 and Rio's Quarterly Report on Form 10-Q and the related unaudited financial information for the quarterly period ended March 31, 1998, and certain other publicly available business and financial information relating to Rio and Harrah's that Merrill Lynch deemed relevant; (ii) reviewed certain information, including financial forecasts, relating to the business, earnings, cash flow, assets, liabilities and prospects of Rio and Harrah's, as well as the amount and timing of the cost savings and related expenses and synergies expected to result from the Merger furnished to Merrill Lynch by Rio and Harrah's, respectively; (iii) conducted discussions with members of senior management and representatives of Rio and Harrah's concerning their respective businesses and prospects before and after giving effect to the Merger; (iv) reviewed the historical market prices, valuation 26 multiples and trading activity for Rio Common Stock and Harrah's Common Stock and compared them with those of certain publicly traded companies which Merrill Lynch deemed to be reasonably similar to Rio and Harrah's, respectively; (v) performed a discounted cash flow analysis based upon information provided by both Rio and Harrah's; (vi) compared the proposed financial terms of the Merger with the financial terms of certain other transactions which Merrill Lynch deemed to be relevant; (vii) reviewed the potential pro forma impact of the Merger on the combined entity's pro forma operating results and financial condition; (viii) participated in certain discussions and negotiations among representatives of Rio and Harrah's and their financial and legal advisors; (ix) reviewed the Merger Agreement; and (x) reviewed such other financial studies and analyses and took into account such other matters as Merrill Lynch deemed necessary, including Merrill Lynch's assessment of general economic, market and monetary conditions. In preparing the Merrill Lynch Opinion, Merrill Lynch assumed and relied on, with Rio's consent, the accuracy and completeness of all information supplied or otherwise made available to Merrill Lynch or discussed with or reviewed by or for Merrill Lynch by Rio and Harrah's, or otherwise publicly available, and did not independently verify such information or undertake an independent evaluation or appraisal of any of the assets or liabilities of Rio or Harrah's. In addition, although representatives of Merrill Lynch visited certain properties of both Rio and Harrah's, Merrill Lynch did not assume any obligation to conduct, nor has it conducted, any physical inspection of the properties or facilities of Rio or Harrah's. With respect to the financial forecast information furnished to or discussed with Merrill Lynch by Rio and Harrah's (including projected cost savings and operating synergies resulting from the Merger), Merrill Lynch assumed that such forecasts have been reasonably prepared and reflected the best currently available estimates and judgment of Rio's or Harrah's management as to the expected future financial performance of Rio or Harrah's, as the case may be. Merrill Lynch further assumed, with Rio's consent, that the Merger will qualify as a tax-free reorganization for U.S. federal income tax purposes and will be accounted for as a purchase under GAAP. The matters considered by Merrill Lynch in arriving at the Merrill Lynch Opinion are necessarily based on numerous macroeconomic, market, operating, financial and other conditions and assumptions with respect to industry performance, general business and economic conditions and other matters as they existed and could be evaluated on, and on the information made available to Merrill Lynch, as of the date of such opinion. Many of such factors are beyond the control of Rio and Harrah's, and involve the application of complex methodologies and educated judgment. Any estimates contained in Merrill Lynch's analyses are not necessarily indicative of actual past or future results or values, which may be significantly more or less favorable than as set forth therein. Estimated values do not purport to be appraisals and do not necessarily reflect the prices at which businesses or companies may be sold in the future and such estimates are inherently subject to uncertainty. The Merrill Lynch Opinion does not present a discussion of the relative merits of the Merger as compared with any other business plan or opportunity that might be presented to Rio, including alternative business combinations with third parties, or the effect of any other arrangement in which Rio might engage. Merrill Lynch assumed that in the course of obtaining the necessary regulatory or other consents and approvals (contractual or otherwise) for the Merger, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that will have a material adverse effect on the contemplated benefits of the Merger. Although at various times during the course of its engagement, Merrill Lynch contacted other parties regarding potential transactions involving Rio, Merrill Lynch was not specifically authorized by Rio to solicit third-party indications of interest in Rio in connection with its evaluation of the Exchange Ratio. At the meetings of the Rio Board held on August 9, 1998 and September 3, 1998, Merrill Lynch presented certain financial analyses accompanied by written materials in connection with the delivery of its fairness opinion. The following is a summary of the material financial and comparative analyses performed by Merrill Lynch in arriving at the Merrill Lynch Opinion. 27 The focus of Merrill Lynch's analysis was its calculation of the relative valuations of both Rio and Harrah's. Merrill Lynch valued both Harrah's and Rio using the various analyses described below and calculated the ratio of the value of Harrah's to the value of Rio. Using the public comparable analysis described below, Merrill Lynch calculated a range of implied exchange ratios of 0.89x to 1.00x (based on management projections) and 0.74x to 0.91x (based on street estimates). Using the discounted cash flow analysis described below, Merrill Lynch calculated a range of implied exchange ratios of 0.74x to 0.78x (based on the EBITDA multiple method) and 0.79x to 0.83x (based on the perpetuity growth method). Finally, using the pro forma contribution analysis described below, Merrill Lynch calculated a range of implied exchange ratios of 0.89x to 1.05x. In each such case, Merrill Lynch found that, when compared to the proposed exchange ratio of 1.00x, each of the foregoing analyses supported its opinion of fairness. To reach these conclusions, Merrill Lynch performed the following analyses: HISTORICAL TRADING PERFORMANCE AND CURRENT CAPITALIZATION ANALYSIS. Merrill Lynch reviewed certain trading information for each of Rio and Harrah's and, on the basis thereof, calculated their respective trading multiples based on closing stock prices of $17.00 for Rio as of August 6, 1998, and $20.13 for Harrah's as of August 7, 1998. Merrill Lynch then calculated Rio's Market Capitalization (defined as the product of the number of shares outstanding and share price, plus total financial debt, less cash) as a multiple of last twelve months ("LTM") (as of June 30, 1998), estimated 1998 and estimated 1999 sales, EBITDA (earnings before interest, taxes, depreciation and amortization) and EBIT (earnings before interest and taxes) and share price as a multiple of LTM (as of June 30, 1998) and estimated 1998 and estimated 1999 EPS (earnings per share). Estimated sales, EBITDA and EBIT were based on Merrill Lynch research dated July 24, 1998. Estimated EPS was based on First Call consensus as of August 4, 1998. For Rio, Market Capitalization as a multiple of LTM, estimated 1998 and estimated 1999 sales were 1.68x, 1.72x and 1.43x, respectively; of LTM, estimated 1998 and estimated 1999 EBITDA were 7.1x, 7.3x and 5.5x, respectively; and of LTM, estimated 1998 and estimated 1999 EBIT were 9.7x, 10.1x and 7.6x, respectively. For Rio, share price as a multiple of LTM, estimated 1998 and estimated 1999 EPS were 13.4x, 14.0x and 10.8x, respectively. Merrill Lynch then calculated Harrah's Market Capitalization as a multiple of LTM, estimated 1998 and estimated 1999 sales, EBITDA and EBIT and share price as a multiple of LTM, estimated 1998 and estimated 1999 EPS. Estimated sales, EBITDA and EBIT were based on Merrill Lynch research dated July 23, 1998. Estimated EPS was based on First Call consensus as of August 4, 1998. For Harrah's, Market Capitalization as a multiple of LTM, estimated 1998 and estimated 1999 sales were 2.03x, 1.71x and 1.48x, respectively; of LTM, estimated 1998 and estimated 1999 EBITDA were 8.0x, 6.8x and 5.6x, respectively; and of LTM, estimated 1998 and estimated 1999 EBIT were 10.9x, 10.0x and 8.0x, respectively. For Harrah's, share price as a multiple of LTM, estimated 1998 and estimated 1999 EPS were 17.2x, 15.0x and 12.3x, respectively. Merrill Lynch also reviewed the stock price and trading volume history for Rio for the period August 4, 1997 through August 4, 1998 and compared such information to performance of the Standard & Poor's 500 Index, the Mid Cap Companies (as defined below) and the Large Cap Companies (as defined below). Merrill Lynch also reviewed the stock price for Harrah's for the period July 1, 1997 through August 4, 1998 and the trading volume history for Harrah's for the period August 4, 1997 through August 4, 1998, and compared such information to performance of the Standard & Poor's 500 Index and the Large Cap Companies. Merrill Lynch also performed an historical analysis of the Exchange Ratio for each trading day during the three year period ended August 6, 1998. The analysis showed an implied exchange ratio ranging from a high of 1.36x to a low of 0.40x with a current implied exchange ratio of 0.85x which compared favorably to the 1.00x exchange ratio fixed in the Merger Agreement. The analysis also showed an implied premium of the offer ratio to the implied exchange ratio ranging from negative 26.2% to positive 150.0% with a current implied premium of the offer ratio to the implied exchange ratio of positive 18.0%. 28 SELECTED COMPARABLE PUBLICLY TRADED COMPANY ANALYSIS. Using publicly available information and estimates of future financial results published by First Call and taken from recent research reports, Merrill Lynch compared certain financial and operating information and ratios and projected financial performance for both Rio and Harrah's with the corresponding financial and operating information and projected financial performance for a group of publicly traded companies engaged primarily in the gaming industry which Merrill Lynch deemed to be reasonably comparable to Rio and Harrah's, respectively, for the purpose of its analysis. The publicly traded gaming companies chosen by Merrill Lynch as reasonably similar to Rio included: Anchor Gaming, Primadonna Resorts, Boyd Gaming, Aztar and Rio (the "Mid Cap Companies") and Hilton Hotels, Mirage Resorts, MGM Grand, Circus Circus Enterprises, Sun International, Trump Hotel & Casino Resorts and Harrah's (the "Large Cap Companies"). The publicly traded gaming companies chosen by Merrill Lynch as reasonably similar to Harrah's were the Large Cap Companies (together with the Mid Cap Companies, the "Comparable Companies"). Merrill Lynch analyzed the estimated 1998 and estimated 1999 price to earnings multiples ("P/E Multiple") of the Large Cap Companies and the Mid Cap Companies. For the Large Cap Companies, Merrill Lynch observed that the estimated 1998 P/E Multiples ranged from 14.4x to 22.7x with a mean of 18.4x and estimated 1999 P/E Multiples ranged from 11.8x to 16.5x with a mean of 14.1x. For Mid Cap Companies, Merrill Lynch observed that the estimated 1998 P/E Multiples ranged from 9.7x to 35.0x with a mean of 12.3x and estimated 1999 P/E Multiples ranged from 8.6x to 32.8x with a mean of 10.5x. Merrill Lynch also analyzed estimated 1998 EBITDA and estimated 1999 EBITDA for the Large Cap Companies and the Mid Cap Companies. Merrill Lynch observed that estimated 1998 EBITDA multiples ranged from 6.5x to 13.7x with a mean of 9.1x for Large Cap Companies and from 4.5x to 7.3x with a mean of 5.7x for Mid Cap Companies. Merrill Lynch also analyzed the ratio of estimated 1999 P/E Multiples to five year earnings per share growth, which ranged from 0.6x to 1.0x with a mean of 0.8x for Large Cap Companies and 0.5x to 3.3x with a mean of 0.7x for Mid Cap Companies. Utilizing the above observations, Merrill Lynch then derived a range of multiples to apply to Rio's estimated 1998 net income, estimated 1999 net income and estimated 1998 EBITDA. Using the Large Cap Companies, the multiples ranged from 14.0x to 18.0x for estimated 1998 net income, 12.0x to 15.0x for estimated 1999 net income and 6.5x to 9.0x for estimated 1998 EBITDA. For the Mid Cap Companies, the multiples ranged from 12.0x to 14.0x for estimated 1998 net income, 10.0x to 12.0x for estimated 1999 net income and 5.0x to 7.0x for estimated 1998 EBITDA. Utilizing the above multiples and Rio management estimates of 1998 net income of $34.6 million, 1999 net income of $40.5 million and 1998 EBITDA of $108.1 million, based on its analysis, Merrill Lynch derived a range of equity per share values of Rio Common Stock of $17.00 to $23.00. Utilizing these multiples and street estimates (based on First Call consensus as of August 4, 1998 for net income and Merrill Lynch research as of July 24, 1998 for EBITDA) of 1998 net income of $30.4 million, 1999 net income of $39.3 million and 1998 EBITDA of $97.6 million, based on its analysis, Merrill Lynch derived a range of equity per share values of Rio Common Stock of $14.00 to $21.00. Utilizing the above multiples and Harrah's management estimates of 1998 net income of $133.0 million, 1999 net income of $159.5 million and 1998 EBITDA of $510.8 million, based on its analysis, Merrill Lynch derived a range of equity per share values of Harrah's Common Stock of $19.00 to $23.00. In calculating equity values, Merrill Lynch assumed that Rio had net financial debt of $373.1 million, option proceeds of $49.5 million and 28.2 million fully diluted shares outstanding and Harrah's had net financial debt of $1,944.4 million, option proceeds of $128.7 million and 108.4 million fully diluted shares outstanding. None of the companies utilized in the above analysis for comparative purposes (other than Rio and Harrah's) is, of course, identical to Rio or Harrah's. Accordingly, a complete analysis of the results of the foregoing calculations cannot be limited to a quantitative review of such results and involves complex considerations and judgments concerning differences in historical and projected financial and operating 29 characteristics of the Comparable Companies and other factors that could affect the public trading value of the Comparable Companies as well as that of Rio or Harrah's. In addition, the multiples discussed above are based on projections prepared by research analysts using only publicly available information. Accordingly, such estimates may or may not prove to be accurate. DISCOUNTED CASH FLOW ANALYSIS. Merrill Lynch performed a discounted cash flow analysis of Rio. Merrill Lynch used both the EBITDA multiple method (based on multiples of 6.0x to 8.0x of 2003 EBITDA) and the perpetuity growth method (based on perpetual 2% to 3% growth of free cash flows) to calculate terminal value. Discount rates ranged from 11% to 13% based on estimates of comparable gaming companies' weighted average cost of capital. Using the EBITDA multiple method, Merrill Lynch calculated a range of equity per share values of Rio Common Stock of $15.75 to $25.28. Using the perpetuity growth method, Merrill Lynch calculated a range of equity per share values of Rio Common Stock of $13.76 to $23.44. Merrill Lynch also performed a discounted cash flow valuation sensitivity based on one, two and three percentage changes in EBIT margin for Rio. Using the EBITDA multiple method (based on multiples of 6.0x to 8.0x of 2003 EBITDA), Merrill Lynch calculated a range of equity per share values of Rio Common Stock of $12.60 to $29.37. Using the perpetuity growth method, Merrill Lynch calculated a range of equity per share values of Rio Common Stock of $10.65 to $27.59. Merrill Lynch also performed a discounted cash flow analysis of Harrah's. Merrill Lynch used both the EBITDA multiple method (based on multiples of 7.0x to 9.0x of 2003 EBITDA) and the perpetuity growth method (based on perpetual 3% to 4% growth of free cash flows) to calculate terminal value. Discount rates ranged from 11% to 13% based on estimates of comparable gaming companies' weighted average cost of capital. Under the EBITDA multiple method, Merrill Lynch calculated a range of equity per share values of Harrah's Common Stock of $21.17 to $32.56. Using the perpetuity growth method, Merrill Lynch calculated a range of equity per share values of Harrah's Common Stock of $16.46 to $29.65. Merrill Lynch also performed a discounted cash flow valuation sensitivity to EBIT margin for Harrah's. Using the EBITDA multiple method (based on multiples of 7.0x to 9.0x of 2003 EBITDA), Merrill Lynch calculated a range of equity per share values of Harrah's Common Stock of $16.75 to $38.22. Using the perpetuity growth method, Merrill Lynch calculated a range of equity per share values of Harrah's Common Stock of $12.33 to $35.34. PRO FORMA CONTRIBUTION ANALYSIS. Merrill Lynch analyzed certain estimated balance sheet and income statement data for both Rio and Harrah's. The analysis showed that Rio would contribute 16.1%, 17.2%, 18.0% and 20.3%, respectively, to 1999 pro forma sales, EBITDA, EBIT and net income and 16.2%, 18.1% 19.0% and 18.6% to 2000 pro forma sales, EBITDA, EBIT and net income. IMPLIED EXCHANGE RATIO ANALYSIS. Merrill Lynch calculated the implied exchange ratio by comparing the theoretical values of Rio Common Stock and Harrah's Common Stock (i) determined by applying the selected comparable publicly traded company analysis discussed above, (ii) the discounted cash flow analysis discussed above and (iii) the pro forma contribution analysis discussed above. Using the public comparables analysis, Merrill Lynch calculated an implied exchange ratio of 0.89x to 1.00x (based on management projections) and 0.74x to 0.91x (based on street estimates). Using the discounted cash flow analysis, Merrill Lynch calculated an implied exchange ratio of 0.74x to 0.78x (using the EBITDA multiple method) and 0.79x to 0.83x (using the perpetuity growth method). Using the pro forma contribution analysis, Merrill Lynch calculated an implied exchange ratio of 0.89x to 1.05x. The ranges of implied exchange ratio, derived using this analysis, when compared to the 1.00x exchange ratio fixed in the Merger Agreement, supported Merrill Lynch's opinion of fairness. In addition to comparing the proposed exchange ratio to the relative valuations of Rio and Harrah's, Merrill Lynch performed a selected comparable transactions analysis and a merger consequences analysis, each of which, as described below, supported Merrill Lynch's opinion of fairness. 30 SELECTED COMPARABLE TRANSACTIONS ANALYSIS. Merrill Lynch reviewed certain publicly available information regarding certain selected mergers and business combinations in the gaming sector (collectively, the "Comparable Transactions"). The Comparable Transactions, in reverse chronological order of public announcement, include, among others, the following: the acquisition of Grand Casinos, Inc. by Hilton Hotels Corp.; the acquisition of Casino Magic Corp. by Hollywood Park, Inc.; the acquisition of Harveys Casino Resorts by Colony Capital, Inc.; the acquisition of Station Casinos, Inc. by Crescent Real Estate Equities Company; the acquisition of Showboat, Inc. by Harrah's Entertainment, Inc.; the acquisition of ITT Corporation by Starwood Lodging Corp.; the acquisition of Griffin Gaming & Equipment Inc. by Sun International Hotels, Ltd.; the acquisition of Bally Entertainment Corp. by Hilton Hotels Corp.; the acquisition of Par-a-Dice Gaming Corp. by Boyd Gaming Corp.; the acquisition of Gold Strike Resorts by Circus Circus Enterprises Inc.; and the acquisition of Caesars World, Inc. by ITT Corporation. Merrill Lynch noted that certain of the Comparable Transactions were still pending at the time of its analysis. This analysis was only applied in relation to Rio. Merrill Lynch compared certain financial ratios for the Comparable Transactions to those of the Merger. Merrill Lynch compared the prices paid in the Comparable Transactions in terms of, among other things, the Transaction Value (defined as offer value plus long term debt plus short term debt less cash less options proceeds) as multiples of LTM EBITDA and Forward Year EBITDA (based on annual estimates from contemporaneous equity research reports, if available). An analysis of the multiples for the Comparable Transactions produced the following results: (i) Transaction Value as a multiple of LTM EBITDA yielded a range of 5.1x to 13.4x, with a mean of 8.8x and median of 9.2x; and (ii) Transaction Value as a multiple of Forward Year EBITDA yielded a range of 5.4x to 10.4x, with a mean of 8.0x and median of 8.3x. Based on its analysis of these multiples, Merrill Lynch applied a range of multiples for Comparable Transactions of LTM EBITDA of 7.0x to 11.0x to corresponding financial data for Rio and derived a range of equity per share values of Rio Common Stock of $13.25 to $27.25. Also, based on its analysis, Merrill Lynch applied a range of multiples for Comparable Transactions of Forward EBITDA of 6.5x to 9.0x to Forward EBITDA for Rio, and derived a range of equity per share values of Rio Common Stock of $18.00 to $29.25 (based on management's estimate of Forward EBITDA) and $15.50 to $26.00 (based on First Call consensus of Forward EBITDA). Based on an assumed per share value of the merger of $20.13 (which was the value of the exchange ratio as of August 7, 1998), Merrill Lynch concluded that this analysis supported its opinion of fairness. MERGER CONSEQUENCES ANALYSIS. Merrill Lynch analyzed certain pro forma effects which could result from the Merger, based on financial forecasts provided by Rio and Harrah's respective managements, and First Call consensus estimates. Merrill Lynch assumed the Merger would be accounted for as a purchase under GAAP. Management of Rio and Harrah's also provided Merrill Lynch with projections of certain combination benefits and revenue enhancements ("synergies") that are expected to occur as a result of the Merger. Assuming no synergies and based on both First Call consensus estimates and management estimates, the analysis indicated that the Merger would be dilutive to projected earnings per share in 1999, 2000 and 2001. Assuming synergies of approximately $14.3 million (which was the midpoint of the estimates given by Rio and Harrah's managements) and based on both First Call consensus estimates and management estimates, the analysis showed that the Merger would be accretive to projected earnings per share in 1999, 2000 and 2001. Merrill Lynch concluded that this analysis supported an opinion of fairness. The actual results achieved by the combined company may vary from projected results, and the variation may be material. The summary set forth above does not purport to be a complete description of the analyses performed by Merrill Lynch in arriving at its opinion or of its presentation to the Rio Board. The preparation of financial analyses and fairness opinions is a complex process and is not necessarily susceptible to partial analysis or summary description. Merrill Lynch believes that its analyses (and the summary set forth above) must be considered as a whole, and that selecting portions of such analyses and of the factors considered by it, without considering all such analyses and factors, could create an incomplete and misleading view of 31 the processes underlying the analyses conducted by Merrill Lynch and set forth in the Merrill Lynch Opinion. Merrill Lynch has not made any attempt to assign specific weights to particular analyses in preparing its opinion. In performing its analyses, Merrill Lynch made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond Harrah's, Rio's and Merrill Lynch's control. Any estimates contained in Merrill Lynch's analyses are not necessarily indicative of actual past or future results or values, which may be significantly more or less favorable than such estimates. Estimated values of companies do not purport to be appraisals and do not necessarily reflect the prices at which businesses or companies may be sold in the future. Because such estimates are inherently subject to uncertainty, none of Merrill Lynch, Rio, Harrah's or any other person assumes responsibility in the event that actual results of operations are different from the results assumed in such estimates. Merrill Lynch did not express any opinion as to the prices at which Harrah's Common Stock will trade following the announcement or consummation of the Merger, which, Merrill Lynch noted, might vary depending upon, among other factors, changes in interest rates, dividend rates, market conditions, general economic conditions and other factors that generally influence the prices of securities. The opinion of Merrill Lynch did not address the relative merits of the Merger and alternative business combinations with third parties. The Rio Board selected Merrill Lynch to render a fairness opinion because Merrill Lynch is an internationally recognized investment banking firm with substantial experience in transactions similar to the Merger and because it is familiar with Rio and its business. Merrill Lynch is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, secondary distributions of listed and unlisted securities and private placements. Pursuant to letter agreements dated February 18, 1998 and August 9, 1998, Rio has agreed to pay Merrill Lynch a fee in cash equal to $5.1 million upon consummation of the Merger. The fee payable to Merrill Lynch is not contingent upon the contents of the opinion delivered. In addition, Rio has agreed to reimburse Merrill Lynch for its reasonable out-of-pocket expenses, including, without limitation, the reasonable fees and disbursements of its legal counsel, and to indemnify Merrill Lynch and certain related persons against certain liabilities arising out of or in conjunction with its rendering of services under its engagement, including certain liabilities under the federal securities laws. In the ordinary course of its business, Merrill Lynch may actively trade in the securities of Rio and Harrah's for its own account and the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities. INTERESTS OF CERTAIN PERSONS IN THE MERGER In considering the recommendation of the Rio Board with respect to the Merger, stockholders of Rio should be aware that the directors and executive officers of Rio have certain interests in the Merger that may be substantial or in addition to the interests of stockholders of Rio generally. The Rio Board was aware of these interests and considered them, among other factors, in approving the Merger Agreement. These interests are summarized below. INTERESTS IN COMMON STOCK AND OPTIONS As of October 5, 1998, the executive officers and directors of Rio beneficially owned an aggregate amount of 4,105,399 shares of Rio Common Stock, which will be treated in the same manner as shares of Rio Common Stock held by other stockholders. As of October 5, 1998, the executive officers of Rio had the right to acquire 1,745,000 shares of Rio Common Stock upon the exercise of options granted to such executive officers pursuant to Rio's option plans, and the non-employee directors of Rio had the right to acquire 76,000 shares of Rio Common Stock upon the exercise of options granted to such non-employee directors pursuant to Rio's option plans. Under the terms of the option plans, all of such outstanding options will become fully vested and 32 immediately exercisable upon consummation of the transactions contemplated by the Merger Agreement. In addition, upon consummation of the Merger, subject, if necessary, to obtaining consents from the holders thereof, each unexpired and unexercised option to purchase shares of Rio Common Stock (individually an "Option" and collectively the "Options") previously granted by Rio under any of Rio's option plans will be converted into an option to acquire the same number of shares of Harrah's Common Stock (a "Substitute Option"). The exercise price per share of Harrah's Common Stock subject to each Substitute Option will be equal to the exercise price per share of Rio Common Stock subject to the relevant Option. See "The Merger Agreement--Treatment of Rio Stock Options." It is anticipated that written consents to the conversion of the Options into Substitute Options will be obtained from each executive officer and director of Rio. The Substitute Options will continue to be exercisable following the Effective Time in accordance with the terms of Rio's option plans, except that the current non-employee directors of Rio will be able to exercise such Substitute Options for nine months following the Effective Time. FUTURE CONSULTING AND EMPLOYMENT AGREEMENTS It is anticipated that Harrah's will enter into consulting agreements with Anthony A. Marnell II and James A. Barrett, Jr., which will take effect on the later of April 1, 1999 or 120 days following the Effective Time and continue in effect for three years unless earlier terminated (after the first year) by either party on sixty days' notice. Messrs. Marnell and Barrett will remain employees of Rio and continue to be paid their current salaries until the consulting agreements take effect. Messrs. Marnell and Barrett are expected to be paid $600,000 and $400,000, respectively, per year under the consulting agreements as compensation for performing specified services and agreeing not to compete with Harrah's in a defined geographic area. Each consulting agreement also will provide that Mr. Marnell or Mr. Barrett, as the case may be, will be entitled to exercise his Substitute Options during the consulting period and, depending on the circumstances, up to one year thereafter. The consulting agreements also are expected to provide that each of Messrs. Marnell and Barrett will become entitled to receive payment of the balance payable under such agreement upon a change in control of Harrah's occurring while such agreement is in effect. It also is expected that Harrah's will enter into employment agreements with Ronald J. Radcliffe and I. Scott Bogatz. Mr. Radcliffe's agreement is expected to be a one-year agreement to serve as Vice President Finance and Administration of Rio. He is expected to receive his current annual salary of $240,000, a guaranteed bonus of $100,000 payable in January 2000 if he continues in his employment through December 31, 1999, and a grant of options to purchase 10,000 shares of Harrah's Common Stock that will vest on December 31, 1999. Mr. Radcliffe will continue to participate in Rio's employee benefit plans and will be eligible to participate in Harrah's Executive Deferred Compensation Plan (the "Harrah's EDCP") and certain other Harrah's executive incentive plans. Mr. Bogatz's agreement is expected to be a four-year agreement to serve as Vice President and General Counsel of Rio. He is expected to receive his current annual salary of $170,000, subject to annual reviews with his next review scheduled for January 1999. It is expected he will continue to participate in Rio's benefit plans and to commence participation in Harrah's benefit plans in January 2000. Following the Effective Time, he will be eligible for certain of Harrah's executive incentive programs, including participation in Harrah's annual management bonus for the plan year 1999 and participation in Harrah's EDCP. Mr. Bogatz also will receive a grant of options to purchase 20,000 shares of Harrah's Common Stock that will vest in annual 25% increments over a four-year period based on his continued employment. The foregoing employment agreements of Mr. Radcliffe and Mr. Bogatz will replace and supersede their current employment agreements with Rio. The terms of the consulting and employment agreements described above are still being negotiated and are subject to further change. 33 EMPLOYMENT AGREEMENT COMPENSATION Rio and its subsidiaries have employment agreements with certain of their executive officers which provide for certain payments to the executive officers upon a change in control of Rio. The Merger would be considered a change in control of Rio under the terms of those employment agreements. The payments vary according to the terms of the respective employment agreements. Upon the Effective Time, the executive officers of Rio who have employment agreements with such change in control provisions will be entitled to receive change of control payments. Such payments will be $300,000 to Ronald J. Radcliffe and $200,000 to I. Scott Bogatz. No other amounts are required to be paid upon a change in control or termination pursuant to such executive officers' respective employment agreements. Messrs. Radcliffe and Bogatz each will be given the opportunity to defer up to 50% of such change in control payments into Harrah's Deferred Compensation Plan (the "Harrah's DCP"). By mutual agreement between Rio and David P. Hanlon, Mr. Hanlon's employment agreement with Rio was terminated effective October 9, 1998. Pursuant to the terms of Mr. Hanlon's employment agreement, he was paid a base salary termination payment of $2,000,000, and was reimbursed expenses in the amount of $30,000. In addition, the Rio Board approved an acceleration of vesting of options to purchase 200,000 shares of the Company's common stock, exercisable for a period of two years from October 9, 1998. Mr. Hanlon has agreed to a twelve month consulting agreement with Rio for certain specified projects under which Mr. Hanlon will be paid $35,000 per month. INDEMNIFICATION AND INSURANCE The Merger Agreement provides for certain arrangements with respect to the ongoing obligations of Harrah's to indemnify, and maintain insurance on behalf of, the directors and executive officers of Rio in respect of certain liabilities. See "The Merger Agreement--Certain Covenants--Director and Officer Insurance and Indemnification." SUPPLEMENTAL RETIREMENT AND DEFERRED COMPENSATION PLAN The balance in the account of each participant in the Supplemental Retirement and Deferred Compensation Plan (the "Rio SERP") will become payable in a lump sum at the Effective Time, provided such participant's employment with Rio is terminated at that time. Each individual who participates in the Rio SERP and continues employment with Harrah's or Rio after the Effective Time (except Messrs. Marnell and Barrett) is expected to become a participant in the Harrah's EDCP, effective as of the Effective Time, and will be credited under the Harrah's EDCP with an amount equal to such individual's balance in the Rio SERP, to be administered in accordance with the terms of the Harrah's EDCP. Messrs. Marnell and Barrett will be entitled to participate in the Harrah's DCP, including deferral of their Rio SERP balances into the Harrah's DCP. In the event that the employment of all participants in the Rio SERP were to be terminated as of the Effective Time, the maximum aggregate benefit payable under the Rio SERP would not exceed approximately $425,000. ACCOUNTING TREATMENT OF THE MERGER The Merger will be accounted for under the "purchase" method of accounting, in accordance with GAAP. Under this method of accounting, the purchase price will be allocated to assets acquired and liabilities assumed based on their estimated fair values at the Effective Time. Income of Harrah's will not include income (or loss) of Rio prior to consummation of the Merger, except as provided for in the pro forma financial information. CERTAIN FEDERAL REGULATORY MATTERS The Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act") rules and regulations thereunder require that parties of a certain size to a proposed merger or business combination exceeding a 34 certain size file with the Antitrust Division of the Department of Justice (the "Antitrust Division") and the Federal Trade Commission (the "FTC") Notification and Report Forms ("Forms") with respect to such merger or business combination. The parties thereafter are required to observe a waiting period before consummating the reported transaction. In compliance with the HSR Act, Harrah's filed Forms on August 25, 1998, and Rio filed Forms on August 27, 1998 with the Antitrust Division and the FTC with respect to the Merger. On September 10, 1998, the FTC granted early termination of the waiting period; however, at any time before or after the Effective Time, the Antitrust Division, the FTC, state antitrust authorities or a private person or entity could seek to enjoin the Merger under the antitrust laws. CERTAIN FEDERAL INCOME TAX CONSEQUENCES In the opinion of Latham & Watkins, counsel to Harrah's, and in the opinion of Skadden, Arps, Slate, Meagher & Flom LLP, counsel to Rio, the material federal income tax considerations generally applicable to holders of Rio Common Stock who, pursuant to the Merger, exchange their Rio Common Stock solely for Harrah's Common Stock, are described below. Consummation of the Merger is conditioned upon Harrah's receipt of an opinion from Latham & Watkins and Rio's receipt of an opinion from Skadden, Arps, Slate, Meagher & Flom LLP to the effect that the Merger will qualify for federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"). The discussion below under "--Treatment of Holders of Rio Common Stock" and "--Cash in Lieu of Fractional Shares" assumes that the Merger will be treated in accordance with the opinions of Latham & Watkins and Skadden, Arps, Slate, Meagher & Flom LLP described in the preceding sentence. The discussion below is, and the opinions of Latham & Watkins and Skadden, Arps, Slate, Meagher & Flom LLP will be, based upon current provisions of the Code, currently applicable U.S. Treasury regulations promulgated thereunder, and judicial and administrative decisions and rulings. The opinions of Latham & Watkins and Skadden, Arps, Slate, Meagher & Flom LLP will be based on the facts, representations and assumptions set forth or referred to in such opinions (including representations contained in certificates executed by officers of Harrah's and Rio). The opinions are not binding on the Internal Revenue Service (the "IRS") or the courts, and there can be no assurance that the IRS or the courts will not take a contrary view. No ruling from the IRS has been or will be sought. Future legislative, judicial or administrative changes or interpretations could alter or modify the statements and conclusions set forth herein, and any such changes or interpretations could be retroactive and could affect the tax consequences to the stockholders of Harrah's and Rio. The discussion below and the opinions of Latham & Watkins and Skadden, Arps, Slate, Meagher & Flom LLP do not purport to deal with all aspects of federal income taxation that may affect particular stockholders in light of their individual circumstances, and is not intended for stockholders subject to special treatment under the federal income tax law (including insurance companies, tax-exempt organizations, financial institutions, broker-dealers, foreign persons, stockholders who hold their stock as part of a hedge, appreciated financial position, straddle or conversion transaction, stockholders who do not hold their stock as capital assets and stockholders who have acquired their stock upon the exercise of employee options or otherwise as compensation). In addition, the discussion below and the opinions do not consider the effect of any applicable state, local or foreign tax laws. EACH HOLDER OF RIO COMMON STOCK IS URGED TO CONSULT ITS TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO IT OF THE TRANSACTION DESCRIBED HEREIN, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF CHANGES IN APPLICABLE TAX LAWS. TREATMENT OF HOLDERS OF RIO COMMON STOCK. Except as discussed below under "--Cash in Lieu of Fractional Shares," each holder of Rio Common Stock who, pursuant to the Merger, exchanges Rio Common Stock for Harrah's Common Stock will not recognize gain or loss upon such exchange. Such 35 holder's tax basis in the Harrah's Common Stock received pursuant to the Merger will be equal to its tax basis in the Rio Common Stock surrendered (excluding any portion of its tax basis allocated to fractional shares), and its holding period for the Harrah's Common Stock will include its holding period for the Rio Common Stock surrendered. CASH IN LIEU OF FRACTIONAL SHARES. A holder of Rio Common Stock who receives cash in lieu of a fractional share of Harrah's Common Stock will be treated as having received such fractional share pursuant to the Merger and then as having exchanged such fractional share for cash in a redemption by Harrah's. Any gain or loss attributable to fractional shares generally will be capital gain or loss. The amount of such gain or loss will be equal to the difference between the portion of the holder's tax basis in the Rio Common Stock surrendered in the Merger that is allocated to its fractional share and the cash received in lieu thereof. Any such capital gain or loss will constitute long-term capital gain or loss if the Rio Common Stock has been held by the holder for more than one year at the Effective Time. Long-term capital gain recognized by certain non-corporate stockholders is subject to federal income tax at preferential capital gains rates (i.e., generally at a maximum rate of 20%). TREATMENT OF HOLDERS OF HARRAH'S COMMON STOCK. There will be no federal income tax consequences to the holders of Harrah's Common Stock as a result of the consummation of the Merger. REPORTING REQUIREMENTS AND BACKUP WITHHOLDING. Each stockholder of Rio receiving Harrah's Common Stock as a result of the Merger will be required to retain certain records and file with its federal income tax return a statement setting forth certain facts relating to the Merger. Backup withholding at the rate of 31% may apply with respect to certain payments unless the recipient (i) is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact or (ii) provides a correct taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. A stockholder who does not provide Harrah's with its correct taxpayer identification number may be subject to penalties imposed by the IRS. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against the stockholder's federal income tax liability provided that certain required information is furnished to the IRS. Harrah's will report to stockholders of Harrah's and to the IRS the amount of "reportable payments" and any amount withheld with respect to Harrah's Common Stock during each calendar year. THE FOREGOING GENERAL DESCRIPTION OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES IS NOT TAX ADVICE AND MAY NOT APPLY TO ALL STOCKHOLDERS OF HARRAH'S AND RIO. ACCORDINGLY, EACH STOCKHOLDER OF HARRAH'S AND RIO IS URGED TO CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL OR FOREIGN TAX LAWS. REGULATORY APPROVALS GAMING REGULATION. The gaming operations of each of Harrah's and Rio are subject to extensive regulation, and each of Harrah's, Rio and their respective subsidiaries hold registrations, approvals, gaming licenses or permits in each jurisdiction in which it operates gaming activities. In each such jurisdiction, certain regulatory requirements must be complied with and/or certain approvals must be obtained in connection with the Merger. Harrah's and Rio's obligations to consummate the Merger are subject to the satisfaction at or prior to the Effective Time of the condition that all necessary gaming regulatory approvals and authorizations have been obtained. See "The Merger Agreement--Conditions to Obligations to Effect the Merger." Harrah's has filed an application for approval from, and initiated discussions with, gaming authorities in Nevada, the sole jurisdiction in which Rio conducts gaming, and the sole jurisdiction in which approval 36 of gaming regulators for the Merger is required. Harrah's filed an application with the Nevada Gaming Commission (the "Nevada Commission") on or about August 28, 1998 for approval of the acquisition of control of Rio. As described below, changes in control of Rio through merger, consolidation, stock or asset acquisitions, management or consulting agreements, or any act or conduct by a person whereby he obtains control, may not occur without the prior approval of the Nevada Commission. Entities seeking to acquire control of a registered, publicly traded, gaming corporation must satisfy the Nevada State Gaming Control Board (the "Nevada Board") and Nevada Commission in a variety of stringent standards prior to assuming control of such registered, publicly traded, gaming corporation. The Nevada Commission may also require controlling stockholders, executive officers, directors and other persons having a material relationship or involvement with the entity proposing to acquire control, to be investigated and licensed or found suitable as part of the approval process relating to the transaction. The Merger requires the prior approval of the Nevada Commission upon the recommendation of the Nevada Board. The ownership and operation of casino gaming facilities in Nevada are subject to: (i) the Nevada Gaming Control Act and the regulations promulgated thereunder (collectively, "Nevada Act"); and (ii) various local regulations. Harrah's and Rio's gaming operations are subject to the licensing and regulatory control of the Nevada Commission, the Nevada Board, the Clark County Liquor and Gaming Licensing Board (the "Clark County Board"), the City of Reno and the Douglas County Sheriff's Department ("Douglas"). The Nevada Commission, the Nevada Board, the Clark County Board, the City of Reno and Douglas are collectively referred to as the "Nevada Gaming Authorities." Harrah's Operating Company, Inc., a direct wholly-owned subsidiary of Harrah's ("HOC"), and Harrah's Las Vegas, Inc. ("HLVI") and Harrah's Laughlin, Inc. ("HLI"), each an indirect subsidiary of Harrah's, are required to be licensed by the Nevada Gaming Authorities to enable Harrah's to operate casinos at Harrah's Lake Tahoe, Bill's Lake Tahoe Casino, Harrah's Reno, Harrah's Las Vegas and Harrah's Laughlin. Rio Properties, Inc., a wholly-owned subsidiary of Rio ("Rio Properties"), operates the Rio Suite Hotel & Casino and is required to be licensed by the Nevada Gaming Authorities. Rio Leasing, Inc., a wholly-owned subsidiary of Rio ("Rio Leasing"), is licensed by the Nevada Gaming Authorities as a distributor of gaming devices. HOC, HLVI, HLI, Rio Properties and Rio Leasing are hereinafter collectively referred to as the "Gaming Subsidiaries." The gaming licenses require the periodic payment of fees and taxes and are not transferable. Each of Harrah's and Rio is registered by the Nevada Commission as a publicly traded corporation ("Registered Corporation"), and as such, each is required periodically to submit detailed financial and operating reports to the Nevada Commission and furnish any other information which the Nevada Commission may require. Each of Harrah's and Rio has obtained from the Nevada Gaming Authorities the various registrations, approvals, findings of suitability, permits and licenses required in order to engage in gaming activities in Nevada. The Nevada Gaming Authorities may investigate any individual who has a material relationship to, or material involvement with, Rio, Harrah's or the Gaming Subsidiaries in order to determine whether such individual is suitable or should be licensed as a business associate of a gaming licensee. Officers, directors and certain key employees of Rio, Harrah's or the Gaming Subsidiaries must file applications with the Nevada Gaming Authorities and may be required to be licensed or found suitable by the Nevada Gaming Authorities. Officers, directors and key employees who are actively and directly involved in gaming activities of Rio or Harrah's may be required to be licensed or found suitable by the Nevada Gaming Authorities. The Nevada Gaming Authorities may deny an application for licensing for any cause which they deem reasonable. A finding of suitability is comparable to licensing, and both require submission of detailed personal and financial information followed by a thorough investigation. The applicant for licensing or a finding of suitability must pay all the costs of the investigation. Changes in licensed positions must be reported to the Nevada Gaming Authorities and in addition to their authority to deny an application for a finding of suitability or licensure, the Nevada Gaming Authorities have jurisdiction to disapprove a change in a corporate position. 37 If the Nevada Gaming Authorities were to find an officer, director or key employee unsuitable for licensing or unsuitable to continue having a relationship with Rio, Harrah's or the Gaming Subsidiaries, Rio, Harrah's or the Gaming Subsidiaries would have to sever all relationships with such person. In addition, the Nevada Commission may require Rio, Harrah's or the Gaming Subsidiaries to terminate the employment of any person who refuses to file appropriate applications. Determinations of suitability or of questions pertaining to licensing are not subject to judicial review in Nevada. Harrah's, and Rio, so long as Rio remains a Registered Corporation, may not make a public offering of its securities without the prior approval of the Nevada Commission if the securities or the proceeds therefrom are intended to be used to construct, acquire or finance gaming facilities in Nevada, or retire or extend obligations incurred for such purposes. On April 28, 1998, the Nevada Commission granted Harrah's and HOC prior approval to make offerings for a period of one year, subject to certain conditions (the "Harrah's Shelf Approval"). However, the Harrah's Shelf Approval may be rescinded for good cause without prior notice upon the issuance of an interlocutory stop order by the Chairman of the Nevada Board. Such approval does not constitute a finding, recommendation or approval by the Nevada Commission or the Nevada Board as to the accuracy or adequacy of the prospectus or the investment merits of the securities. Any representation to the contrary is unlawful. The issuance of Harrah's Common Stock in connection with the acquisition of control of Rio will be pursuant to the Harrah's Shelf Approval. The failure to obtain the required approval of the Merger and the issuance of Harrah's Common Stock or the failure to comply with the procedural requirements prescribed by any applicable gaming regulatory authority or the failure of Harrah's or Rio to qualify or make disclosures or applications as required under the laws and regulations of any applicable gaming regulatory authority may result in the loss of license or denial of application for licensure in any such jurisdiction. The foregoing is only a summary of the various applicable gaming regulatory requirements under the Nevada Act. For a complete description of such regulatory requirements, see "Governmental Regulation" in the Annual Report on Form 10-K for the fiscal year ended December 31, 1997 for Harrah's and "Regulation and Licensing" in the Annual Report on Form 10-K for the fiscal year ended December 31, 1997 for Rio. DELISTING AND DEREGISTRATION OF RIO COMMON STOCK; LISTING OF HARRAH'S COMMON STOCK ISSUED IN CONNECTION WITH THE MERGER Rio Common Stock currently is listed for quotation on the NYSE under the symbol "RHC." Upon consummation of the Merger, Rio Common Stock will be delisted from the NYSE and deregistered under Securities Exchange Act of 1934, as amended (the "Exchange Act"). Application will be made for the listing under the symbol "HET" on the NYSE, the Chicago Stock Exchange, the Pacific Exchange and the Philadelphia Stock Exchange of the shares of Harrah's Common Stock to be issued in the Merger. The listing of such shares on the NYSE is a condition to the consummation of the Merger. See "The Merger Agreement--Conditions to Obligations to Effect the Merger." Following the Merger, Rio stockholders will need to exchange their outstanding stock certificates for stock certificates representing shares of Harrah's Common Stock. See "The Merger Agreement--Exchange of Stock Certificates." RESALES OF HARRAH'S COMMON STOCK ISSUED IN CONNECTION WITH THE MERGER; AFFILIATE AGREEMENTS Harrah's Common Stock issued in connection with the Merger will be freely transferable, except that shares of Harrah's Common Stock received by persons who are deemed to be "affiliates" (as such term is defined by Rule 144 under the Securities Act of 1933, as amended (the "Securities Act")) of Rio at the Effective Time may be resold by them only in transactions permitted by the resale provisions of Rule 145 under the Securities Act or as otherwise permitted under the Securities Act. Rio has agreed that it will use all reasonable efforts to cause each of its executive officers and directors and persons who may be deemed to be "affiliates" to execute a written agreement (an "Affiliate Agreement") providing, among other things, that such person will not offer, sell, transfer or otherwise dispose of any of the shares of Harrah's Common Stock obtained as a result of the Merger except in compliance with the Securities Act and the rules and 38 regulations of the Securities and Exchange Commission (the "SEC") thereunder. Each Affiliate Agreement also requires such affiliate to make certain representations with respect to certain tax matters. This summary is qualified in its entirety by reference to the specific provisions of the Affiliate Agreements, the form of which is attached to the Merger Agreement as Annex A. NO RIGHT OF DISSENT Any holder of shares of Rio Common Stock, who does not wish to accept the exchange of such holder's shares of Rio Common Stock for Harrah's Common Stock, will not have a right to dissent and obtain payment of "fair value" for such shares of Rio Common Stock with respect to the Merger Agreement in accordance with applicable statutory procedures of Section 92A.390 of the Nevada Revised Statutes (the "NRS"), because the Rio Common Stock was listed on the NYSE on the record date for the Rio Special Meeting. EFFECT OF THE MERGER ON OUTSTANDING DEBT The Merger will constitute a "change in control" under Rio's outstanding 10-5/8% Senior Subordinated Notes due 2005 and 9-1/2% Senior Subordinated Notes due 2007 (collectively, the "Senior Subordinated Notes") and, consequently, the surviving corporation in the Merger will be required to make an offer to purchase the Senior Subordinated Notes at 101% of the principal amount thereof following the Effective Time. Other than the obligation to make such offer to purchase, the Merger is not expected to have any effect on either issue of the Senior Subordinated Notes.

SUCH SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MERGER AGREEMENT. STOCKHOLDERS OF HARRAH'S AND RIO ARE URGED TO READ THE MERGER AGREEMENT IN ITS ENTIRETY FOR A MORE COMPLETE DESCRIPTION OF THE TERMS AND CONDITIONS OF THE MERGER. THE MERGER The Merger Agreement provides that, subject to the satisfaction or waiver of the conditions to the Merger, Merger Sub will merge with and into Rio, with Rio as the surviving corporation (the "Surviving Corporation"). Immediately following the Merger, Harrah's will contribute the capital stock of the Surviving Corporation to HOC, such that the Surviving Corporation will become an indirect wholly-owned subsidiary of Harrah's, while the holders of Rio Common Stock will become holders of Harrah's Common Stock. If the Merger Agreement is approved by the stockholders of Harrah's and Rio, and the other conditions to the Merger are satisfied or waived, the closing of the Merger will take place no later than the third business day (the "Closing Date") following the date on which the last of the conditions is satisfied or waived, or at such other date agreed to by Harrah's and Rio. On the Closing Date, Harrah's and Rio will cause articles of merger to be filed with the Secretary of State of the State of Nevada as provided in Section 92A.200 of the NRS, and the Merger will become effective upon such filing or such later time as is specified in the articles of merger (the "Effective Time"). Subject to the satisfaction or waiver of the other conditions to the obligations of Harrah's and Rio to consummate the Merger, it is presently expected that the Merger will be consummated by the end of 1998. CONVERSION OF SHARES At the Effective Time: (i) each issued and outstanding share of Rio Common Stock (other than shares that are canceled as described below) will be converted into the right to receive one validly issued, fully paid and non-assessable share of Harrah's Common Stock; (ii) each issued and outstanding share of common stock of Merger Sub will be converted into one share of the Surviving Corporation; and (iii) each share of Rio Common Stock that is owned by Rio as treasury stock or is owned by Harrah's or any of its wholly-owned subsidiaries will be canceled and will cease to exist and no consideration will be delivered in exchange therefor. Based upon the number of shares of common stock of Harrah's and Rio outstanding on the record date for the Harrah's Special Meeting and the record date for the Rio Special Meeting, respectively, Rio's current stockholders will own approximately 19.6% of Harrah's Common Stock that will be outstanding upon completion of the Merger. EXCHANGE OF STOCK CERTIFICATES At or prior to the Effective Time, Harrah's shall deposit with a bank or trust company appointed to act as exchange agent for the purpose of delivering the Merger Consideration to Rio's stockholders (the "Exchange Agent"), (i) certificates evidencing the shares of Harrah's Common Stock issuable in connection with the Merger in exchange for outstanding shares of Rio Common Stock and (ii) cash in an aggregate amount sufficient to pay for fractional shares as described below. Promptly after the Effective Time, the Exchange Agent will mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Rio Common Stock a letter of transmittal and instructions for use in effecting the surrender of such certificates in exchange for the certificates evidencing shares of Harrah's Common Stock and cash in lieu of fractional shares, if any. Upon surrender of certificates for cancellation to the Exchange Agent, together with such letter of transmittal, 40 duly executed, the holder of such certificates will be entitled to receive in exchange therefor that number of whole shares of Harrah's Common Stock equal to the number of shares of Rio Common Stock represented by the certificate so tendered, and the amount of any cash payable in lieu of fractional shares of Harrah's Common Stock and other dividends or distributions which such holder is entitled to receive as provided in the next three paragraphs, and the certificates so surrendered will promptly be canceled. NO FURTHER OWNERSHIP RIGHTS IN RIO COMMON STOCK. All shares of Harrah's Common Stock (and cash in lieu of fractional shares) issued upon the surrender for exchange of certificates which immediately prior to the Effective Time represented shares of Rio Common Stock will be deemed to have been issued in full satisfaction of all rights pertaining to the shares of Rio Common Stock theretofore represented by such certificates, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Rio Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, certificates which immediately prior to the Effective Time represented shares of Rio Common Stock are presented to the Surviving Corporation for any reason, such certificates will be canceled and exchanged in the manner described above. FRACTIONAL SHARES. No fractional shares of Harrah's Common Stock will be issued in the Merger. In lieu of any such fractional shares, each holder of shares of Rio Common Stock outstanding immediately prior to the Effective Time exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Harrah's Common Stock (after taking into account all certificates representing shares of Harrah's Common Stock delivered by such holder) will receive, in lieu thereof, an amount in cash (without interest), rounded up to the nearest cent, equal to such fractional part of a share of Harrah's Common Stock multiplied by the average per share closing price of Harrah's Common Stock (as reported on the NYSE Composite Tape) for the ten consecutive trading days immediately preceding the second business day prior to the Effective Time. DIVIDENDS AND DISTRIBUTIONS. No dividends or other distributions declared or made after the Effective Time with respect Harrah's Common Stock with a record date after the Effective Time will be paid to the holder of any unsurrendered certificate representing shares of Rio Common Stock with respect to the shares of Harrah's Common Stock that the holder thereof is entitled to receive, and no cash payment in lieu of fractional shares will be paid to any such holder until the holder of record of such certificate shall surrender such certificate to Harrah's as described above. Subject to applicable law, following surrender of any such certificate, there will be paid to the record holder of the certificates representing whole shares of Harrah's Common Stock issued in exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to whole shares of Harrah's Common Stock. FAILURE TO EXCHANGE. Any shares of Harrah's Common Stock, and any portion of monies from which cash payments in lieu of fractional shares of Rio Common Stock and any dividends or distributions on shares of Harrah's Common Stock will be made, which remain undistributed to the former stockholders of Rio for twelve months after the Effective Time will be delivered to Harrah's upon demand, and thereafter any former stockholder of Rio who has not previously exchanged certificates which immediately prior to the Effective Time represented shares of Rio Common Stock will thereafter look only to Harrah's for payment of such former stockholder's claim for Harrah's Common Stock, any cash in lieu of fractional shares of Harrah's Common Stock and any amounts in respect of dividends or distributions with respect to Harrah's Common Stock. NO LIABILITY. None of Harrah's, Merger Sub, Rio or the Exchange Agent will be liable to any holder of shares of Rio Common Stock for any shares of Harrah's Common Stock (or cash in lieu of fractional shares of Harrah's Common Stock or any dividends or distributions with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. 41 WITHHOLDING RIGHTS. Harrah's or the Exchange Agent will be entitled to deduct and withhold from the consideration otherwise payable to any holder of certificates which prior to the Effective Time represented shares of Rio Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld, such withheld amounts shall be treated as having been paid to the holder of the shares of Rio Common Stock in respect of which such deduction and withholding was made by Harrah's or the Exchange Agent. LOST CERTIFICATES. If any certificate which prior to the Effective Time represented shares of Rio Common Stock shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen or destroyed and, if required by Harrah's, the posting by such person of a bond in such reasonable amount as Harrah's may direct as indemnity against any claim that may be made against it, the Surviving Corporation or the Exchange Agent with respect to such certificate, the exchange agent will issue in exchange for such lost, stolen or destroyed certificate the shares of Harrah's Common Stock and any cash in lieu of fractional shares and unpaid dividends and distributions on shares of Harrah's Common Stock otherwise deliverable in respect thereof. HOLDERS OF RIO COMMON STOCK SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE A TRANSMITTAL FORM FROM THE BANK OF NEW YORK, THE EXCHANGE AGENT THEREFOR. TREATMENT OF RIO STOCK OPTIONS At the Effective Time, subject, if necessary, to obtaining the consent of the holder thereof, each unexpired and unexercised outstanding option, whether or not then vested or exercisable in accordance with its terms, to purchase shares of Rio Common Stock (the "Rio Options") previously granted by Rio or its subsidiaries under its stock option plans (the "Rio Stock Option Plans"), will be converted automatically into a Substitute Option. After the Effective Time, each Substitute Option will be exercisable at the same exercise price and upon the same other terms and conditions as were applicable to the related Rio Option immediately prior to the Effective Time (including those terms which may have caused such Rio Option to become exercisable in full in connection with the consummation of the transactions contemplated by the Merger Agreement). As soon as practicable after the Effective Time, Harrah's will deliver to the holders of the Substitute Options appropriate notice setting forth such holders' rights pursuant thereto. Harrah's will take all corporate action necessary to reserve for issuance a sufficient number of shares of Harrah's Common Stock for delivery under the Rio Stock Option Plans and, within 30 days after the Effective Time, Harrah's will file a registration statement on Form S-8 (or any successor or other appropriate forms) with respect to the shares of Harrah's Common Stock subject to such options and shall use its best efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such options remain outstanding. Rio (or, if appropriate, any committee administering the Rio Stock Option Plans) will use its best efforts, prior to or as of the Effective Time, to take all necessary actions, pursuant to and in accordance with the terms of the Rio Stock Option Plans and the instruments evidencing the Rio Options, to provide for the conversion of the Rio Options into options to acquire Harrah's Common Stock in the manner described above. Furthermore, Rio will use its best efforts to obtain the consent of the holders of the Rio Options if required in connection with such conversion. The Boards of Directors of Harrah's and Rio will, prior to or as of the Effective Time, take appropriate actions to approve the deemed cancellation of the Rio Options and the deemed grant of options to purchase Harrah's Common Stock for purposes of Section 16(b) of the Exchange Act.

Without limiting the generality of the foregoing and except as expressly contemplated by the Merger Agreement, specifically disclosed in the disclosure schedules thereto, otherwise consented to in writing by Rio, or as would not be reasonably likely to have a material adverse effect on the business, properties, financial condition or results of operations of Harrah's and its subsidiaries, taken as a whole, but excluding the effect of economic changes that are applicable to the gaming industry generally, or the gaming industry in markets in which Harrah's or its subsidiaries conduct business in particular (a "Harrah's Material Adverse Effect"), during the same period, Harrah's and each of its subsidiaries will not: - amend the Articles of Incorporation or Bylaws of Harrah's or HOC; - declare or pay any dividends on or make other distributions in respect of any of its capital stock (other than between any subsidiary of Harrah's and Harrah's or any other subsidiary of Harrah's); - take any action inconsistent with the ordinary course of business and past practice with respect to accounting policies or procedures, unless required by GAAP or the SEC; - authorize or announce any intention to adopt a plan of complete or partial liquidation or dissolution of Harrah's or any of its subsidiaries; - other than in the ordinary course of business and consistent with past practice, waive any rights of substantial value or make any payment of any material liability of Harrah's or any of its subsidiaries before the same comes due in accordance with its terms; - fail to maintain its existing insurance coverage; - enter into any new collective bargaining agreement; - take any action that would cause its representations or warranties set forth in the Merger Agreement, individually or in the aggregate, which are not qualified by materiality not to be true 45 and correct in all material respects or cause those qualified by materiality not to be true and correct, in each case at, or as of any time prior to, the Effective Time; - take any action that would prevent the Merger from qualifying as a reorganization under Section 368(a) of the Code; - acquire any business or assets unrelated to the gaming industry in an amount which exceeds $25 million, with certain exceptions; or - enter into any agreement or announce any intention to take any of the foregoing actions. NO SOLICITATION. Rio will not, directly or indirectly, through any officer, director, employee, financial advisor, representative or agent, (i) solicit, initiate or encourage any inquiries or proposals that constitute, or could reasonably be expected to lead to, a proposal or offer for a merger, consolidation, business combination, sale of substantial assets, sale of shares of capital stock (including without limitation by way of a tender offer) or similar transaction involving Rio or any of its subsidiaries, other than the transactions contemplated by the Merger Agreement (any of the foregoing inquiries or proposals being referred to as an "Acquisition Proposal"), (ii) engage in negotiations or discussions with, provide any non-public information to, or take any action to facilitate inquiries by, any person (or group of persons) other than Harrah's and its affiliates (a "Third Party") relating to any Acquisition Proposal, or (iii) enter into any agreement with respect to any Acquisition Proposal; PROVIDED, HOWEVER, that nothing contained in the Merger Agreement will prevent Rio or the Rio Board from furnishing non-public information to, or entering into discussions or negotiations with, any Third Party in connection with an unsolicited bona fide written proposal for an Acquisition Proposal by such Third Party if and only to the extent that (1) such Third Party has made a written proposal to the Rio Board to consummate an Acquisition Proposal, which proposal identifies a price or range of values to be paid for the outstanding securities or substantially all of the assets of Rio, (2) the Rio Board determines in good faith, after consultation with a financial advisor of nationally recognized reputation, that such Acquisition Proposal is reasonably capable of being completed on substantially the terms proposed and would, if consummated, result in a transaction that would provide greater value to the stockholders of Rio than the transaction contemplated by the Merger Agreement (a "Superior Proposal"), (3) the Rio Board determines in good faith, based on the advice of outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary duties to Rio's stockholders under applicable law and (4) prior to furnishing such non-public information to, or entering into discussions or negotiations with, such Third Party, the Rio Board receives from such Third Party an executed confidentiality and standstill agreement (unless the Rio Board determines in good faith upon the advice of counsel that requiring such Third Party to enter into a standstill agreement would violate such Board's fiduciary duty) with material terms no less favorable to such party than those contained in the Confidentiality Agreements, each dated June 18, 1998, between Harrah's and Rio. Rio also will not release any Third Party from, or waive any provision of, any standstill agreement to which it is a party or any confidentiality agreement between it and another person who has made, or who may reasonably be considered likely to make, an Acquisition Proposal, unless the Rio Board determines in good faith, based on the advice of outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary duties to Rio's stockholders under applicable law. Rio will notify Harrah's orally and in writing promptly after receiving any Acquisition Proposal or any request for non-public information in connection with an Acquisition Proposal or for access to its properties, books or records in connection with an Acquisition Proposal. Such notice must indicate in reasonable detail the identity of the offeror and the terms and conditions of such proposal, inquiry or contact. Rio will (i) keep Harrah's informed of the status (including any change to the material terms) of any such Acquisition Proposal or request for non-public information and (ii) provide to Harrah's as soon as practicable after receipt or delivery thereof with copies of all correspondence and other written material 46 (A) sent or provided to Rio or any of its employees, representatives or agents from any Third Party in connection with any Acquisition Proposal or request for non-public information or (B) sent or provided by Rio or any of its employees, representatives or agents to any Third Party in connection with any Acquisition Proposal or request for non-public information. Except as expressly permitted by the Merger Agreement, neither the Rio Board nor any committee thereof will (i) withdraw or modify, or propose to withdraw or modify, in a manner adverse to Harrah's, the approval or recommendation by the Rio Board or any such committee of the Merger Agreement or the Merger, (ii) approve or cause Rio to enter into a definitive agreement relating to any Acquisition Proposal, or (iii) approve or recommend, or propose to publicly approve or recommend, any Acquisition Proposal. Notwithstanding the foregoing, if Rio has received a Superior Proposal, the Rio Board may, prior to approval of the Merger by Rio's stockholders and subject to this and the following sentences, terminate this Agreement at any time that is more than 48 hours following receipt by Harrah's of written notice advising Harrah's that the Rio Board is prepared to accept such Superior Proposal, specifying the material terms and conditions of such Superior Proposal and identifying the Third Party making such Superior Proposal; PROVIDED, HOWEVER, that concurrently with or immediately after such termination, the Rio Board shall cause Rio to enter into a definitive agreement with respect to such Superior Proposal. Notwithstanding the foregoing, Rio will not be prohibited from taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making any disclosure to Rio's stockholders if, in the good faith judgment of the Rio Board, based on the advice of outside legal counsel, failure to so disclose would be inconsistent with its fiduciary obligations under applicable law; PROVIDED, HOWEVER, that neither Rio nor the Rio Board (nor any committee thereof) will withdraw or modify, or propose publicly to withdraw or modify, its position with respect to the Merger Agreement or the Merger, or approve or recommend, or propose publicly to approve or recommend, an Acquisition Proposal. STOCKHOLDERS' MEETING. The Merger Agreement provides that each of Harrah's and Rio will call a meeting of their respective stockholders to be held as promptly as practicable for the purpose of voting upon the Merger Agreement and the Merger. Harrah's will recommend to its stockholders to approve the Stock Issuance Proposal, and Rio will recommend to its stockholders adoption of the Merger Agreement and approval of such matters. Each of Harrah's and Rio will coordinate and cooperate with the respect to the timing of such meetings and will use its best efforts to hold such meeting as soon as practicable after the date of the Merger Agreement. Each of Harrah's and Rio will use all reasonable efforts to solicit from their respective stockholders proxies in favor of such matters. GOVERNMENTAL APPROVALS. Harrah's and Rio agreed to cooperate with each other and use their best efforts (and, with respect to certain federal, state and local gaming laws, to use their best efforts to cause their respective directors and officers to do so) to promptly prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, registrations, licenses, findings of suitability, consents, variances, exemptions, orders, approvals and authorizations of all third parties and governmental entities which are necessary or advisable to consummate the transactions contemplated by the Merger Agreement, including, without limitation, all filings required under the HSR Act and all applicable federal, state and local gaming laws ("Governmental Approvals"), and to comply (and, with respect to certain federal, state and local gaming laws, to cause their respective directors and officers to so comply) with the terms and conditions of all such Governmental Approvals. Harrah's and Rio agreed to use their reasonable best efforts to (and use their reasonable best efforts to cause their respective officers, directors and affiliates to) file within 30 days after the date of the Merger Agreement, and in all events to file within 60 days after the date of the Merger Agreement, all required initial applications and documents in connection with obtaining the Governmental Approvals (including without limitation under applicable federal, state and local gaming laws) and to act reasonably and promptly thereafter in responding to additional requests in connection therewith. Rio and Harrah's will have the right to review in advance, and to the extent practicable each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to 47 Harrah's or Rio, as the case may be, and any of their respective subsidiaries, directors, officers and stockholders which appear in any filing made with, or written materials submitted to, any third party or any governmental entity in connection with the transactions contemplated by the Merger Agreement. Without limiting the foregoing, each of Harrah's and Rio agreed to notify the other promptly of the receipt of comments or requests from governmental entities relating to Governmental Approvals and to supply the other party with copies of all such correspondence; provided, however, that neither Rio nor Harrah's will be required to supply the other party with copies of correspondence relating to the personal applications of individual applicants except for evidence of filing. Harrah's and Rio also agreed to promptly advise each other upon receiving any communication from any governmental entity whose consent or approval is required for consummation of the transactions contemplated by the Merger Agreement which causes such party to believe that there is a reasonable likelihood that any approval needed from a governmental entity will not be obtained or that the receipt of any such approval will be materially delayed. Harrah's and Rio agreed to take any and all actions reasonably necessary to vigorously defend, lift, mitigate and rescind the effect of any litigation or administrative proceeding adversely affecting the Merger Agreement or the transactions contemplated by the Merger Agreement, including, without limitation, promptly appealing any adverse court or administrative order or injunction to the extent reasonably necessary for the foregoing purposes. Notwithstanding the foregoing or any provision in the Merger Agreement, however, Harrah's will have no obligation or affirmative duty to cease or refrain from the ownership of any assets or properties, or the association with any person or entity which association is material to the operations of Harrah's, whether on the date hereof or any time in the future. DIRECTOR AND OFFICER INSURANCE AND INDEMNIFICATION. From and after the Effective Time, Harrah's will cause the Surviving Corporation to indemnify and hold harmless each present and former director and officer of Rio against any costs or expenses (including attorneys' fees), judgments, fines, losses, claims, damages, liabilities or amounts paid in settlement incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to any matter existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent that Rio would have been permitted under Nevada law and its Articles of Incorporation or Bylaws in effect on the date of the Merger Agreement to indemnify such person. For a period of six years after the Effective Time, Harrah's will maintain or will cause the Surviving Corporation to maintain in effect a directors' and officers' liability insurance policy covering those persons who are covered as of the date of the Merger Agreement by Rio's directors' and officers' liability insurance policy, with coverage in an amount and scope at least as favorable as Rio's existing coverage; provided that in no event will Harrah's or the Surviving Corporation be required to expend in excess of 200% of the annual premium paid by Rio for such coverage, and if the premium would at any time exceed 200% of such amount, then Harrah's or the Surviving Corporation will maintain insurance policies which provide the maximum and best coverage available at an annual premium equal to 200% of such amount. EMPLOYEE BENEFITS. The Merger Agreement provides that Harrah's will cause the Surviving Corporation and its subsidiaries to honor all of Rio's written employment, consulting, severance and termination agreements (including change in control provisions) of the employees of Rio and its subsidiaries. Harrah's acknowledges that consummation of the transactions contemplated by the Merger Agreement will constitute a change in control (or change of control) of Rio (to the extent such concept is applicable) for the purpose of the Rio Stock Option Plans and Rio's other employee benefit plans (causing all outstanding options to become vested and exercisable, all restrictions on outstanding restricted shares to lapse and all participants' accounts in Rio's Supplemental Retirement and Deferred Compensation Plan to become payable in a lump sum). For purposes of determining eligibility to participate, vesting and entitlement to benefits where length of service is relevant under any employee benefit plan or arrangement of Harrah's or the Surviving Corporation, other than for purposes of benefit accrual under any pension plan or where crediting of prior service would result in a duplication of benefits, Rio's employees who after the Closing 48 Date become employees of Harrah's or the Surviving Corporation will receive service credit for service with Rio and any of its subsidiaries to the same extent such service was granted under Rio's employee benefit plans. Nothing in the Merger Agreement (other than the provisions relating to conversion of Rio Options and the provision described in the first sentence of this paragraph) is intended to create any right of employment for any person or to create any obligation for Harrah's or the Surviving Corporation to continue any employee benefit plan of Rio following the Effective Time. Harrah's will, or will cause the Surviving Corporation and its subsidiaries to, (i) waive all limitations as to preexisting conditions exclusions and waiting periods with respect to participation and coverage requirements applicable to Rio's employees under any employee benefit plans that such employees may be eligible to participate in after the Closing Date, other than limitations or waiting periods that are already in effect with respect to such employees and that have not been satisfied as of the Closing Date under any employee benefit plan maintained for such employees immediately prior to the Closing Date, and (ii) use its best efforts to provide each such employee with credit for any co-payments and deductibles paid prior to the Closing Date in satisfying any applicable deductible or out-of-pocket requirements under any employee benefit plans that such employees are eligible to participate in after the Closing Date. For a period of two years immediately following the Closing Date, Harrah's will provide to Rio employees who after the Closing Date become employees of Harrah's, the Surviving Corporation or any of its subsidiaries (other than certain Rio executive and management employees) group health, life and disability benefits and the benefits under a qualified cash or deferred arrangement, within the meaning of Section 401(k) of the Code, which are in the aggregate for all plans combined and for all eligible employees combined, not materially less favorable for such employees than those provided to such employees immediately prior to the Closing Date. OTHER COVENANTS. Each of Harrah's and Rio has agreed: (a) to confer with the other party on a regular and frequent basis regarding ongoing operations and to give prompt notice to the other of, and use all commercially reasonable efforts to cure before the Closing Date, any event, transaction or circumstance which causes or will cause any covenant or agreement under the Merger Agreement to be breached or that renders or will render untrue in any material respect any representation or warranty contained in the Merger Agreement; (b) to file this Proxy Statement/Prospectus and the Registration Statement, (c) to give (and to cause its respective subsidiaries to give) the other party and its representatives access to all its personnel, properties, books, contracts, commitments and records, and to furnish related information reasonably requested by the other party and certain additional financial reports and other information relating to its operations and periods between the date of the Merger Agreement and the Effective Time; (d) to consult with the other party before issuing, and use all reasonable efforts to agree upon, any press release or other public statement concerning the transactions contemplated by the Merger Agreement; (e) to use its reasonable best efforts to take all appropriate actions to consummate the transactions contemplated by the Merger Agreement; (f) to not take any action, or knowingly fail to take any action, that would or would be reasonably likely to adversely affect the tax treatment of the Merger; (g) in the case of Rio only, use all reasonable efforts to deliver the Affiliate Agreements to Harrah's by October 1, 1998; (h) in the case of Harrah's only, use its best efforts to list on the NYSE prior to the Effective Time the shares of Harrah's Common Stock to be issued in the Merger; (i) to use all reasonable efforts to obtain customary "comfort" letters of such party's independent public accountants with respect to the Registration Statement; (j) in the case of Harrah's only, to appoint or take such actions necessary to nominate and seek the election of Anthony A. Marnell II to the Harrah's Board for a term expiring in 2000; and (k) in the case of Rio only, to take, or cause to be taken, all such actions necessary to obtain, at the Effective Time, title insurance coverage for Rio's real property.

In addition, the obligations of Harrah's and Merger Sub to effect the Merger are also subject to the satisfaction of the following conditions: (a) the representations and warranties of Rio in the Merger Agreement shall be true and correct (except for those qualified as to materiality or a Rio Material Adverse Effect (as defined below) which shall be true and correct) as of the date of the Merger Agreement and, except to the extent such representations speak as of an earlier date, as of the Closing Date as though made on and as of the Closing Date, except for (i) changes contemplated by the Merger Agreement and (ii) other than for representations and warranties already qualified as to materiality or a Rio Material Adverse Effect, inaccuracies which, individually or in the aggregate, have not had and are not reasonably likely to have a Rio Material Adverse Effect (the "Rio Representation Bringdown Condition"); (b) Rio shall have performed in all material respects all obligations required to be performed by it under the Merger Agreement, and each of the Rio stockholders that is a party to a Stockholder Support Agreement shall have performed in all material respects all of its obligations thereunder, in each case at or prior to the Closing Date (the "Rio Performance Condition"); (c) between the date of the Merger Agreement and the Effective Date, there shall have been no material adverse change in the business or properties (including Rio's development plans contemplated by its "Phase VI Expansion Plan" and the development plans of its "Phase VI Land"), financial condition or results of operations of Rio and its subsidiaries, taken as a whole, other than changes, if any, resulting from the effect of economic changes which are applicable to the gaming industry generally or the Las Vegas gaming industry in particular; (d) Skadden, Arps, Slate, Meagher & Flom LLP, counsel to Rio, shall have delivered to Rio an opinion, dated as of the Closing Date, to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Code; and (e) Rio shall have received all third-party consents and approvals required to be obtained by Rio, except for such third-party consents and approvals as to which the failure to obtain, either individually or in the aggregate, would not reasonably be expected to result in a Rio Material Adverse Effect, as the case may be.

TERMINATION; TERMINATION FEES AND EXPENSES The Merger Agreement may be terminated at any time prior to the Effective Time, whether before or after approval of the matters presented in connection with the Merger by Rio's stockholders: (a) by mutual written consent of Rio and Harrah's; or (b) by either Harrah's or Rio if the Merger has not been consummated by January 31, 1999 (provided that (i) if the Merger has not been consummated because the requisite governmental approvals have not been obtained and are still being pursued, either Harrah's or Rio may extend such date to May 31, 1999 by providing written notice thereof to the other party on or prior to January 31, 1999 and (ii) the right to terminate the Merger Agreement under this clause (b) will not be available to any party whose failure to fulfill any obligation under the Merger Agreement has been the cause of or resulted in the failure of the Merger to occur on or before such date); or (c) by either Harrah's or Rio if a court of competent jurisdiction or other governmental entity has issued a nonappealable final order, decree or ruling or taken any other nonappealable final action, in each case having the effect of permanently restraining, enjoining or otherwise prohibiting the Merger; or (d) (i) by either Harrah's or Rio, if, at the meeting of Rio's stockholders (including any adjournment or postponement), the requisite vote of the stockholders of Rio in favor of the approval and adoption of the Merger Agreement and the Merger has not been obtained; or (ii) by either Rio or Harrah's, if, at the meeting of Harrah's stockholders (including any adjournment or postponement), the requisite vote of the stockholders of Harrah's in favor of the approval and adoption of the Merger Agreement and the Merger shall not have been obtained; or (e) (i) by Harrah's, if for any reason Rio fails to call and hold the meeting of Rio's stockholders by January 31, 1999; PROVIDED, that Harrah's right to terminate the Merger Agreement under this clause (e)(i) shall not be available if at such time Rio would be entitled to terminate the Merger Agreement under clause (h) below; or (ii) by Rio, if for any reason Harrah's fails to call and hold the meeting of Harrah's stockholders by January 31, 1999; PROVIDED, that Rio's right to terminate the Merger Agreement under this clause (e)(ii) shall not be available if at such time Harrah's would be entitled to terminate the Merger Agreement under clause (h) below; or (f) by Rio, in accordance with the provisions described above under "--No Solicitation," including the notice provision described therein, and the payment by Rio of the termination fee described below; or (g) by Rio, if Harrah's consolidates or merges with or into, or sells all or substantially all of its assets directly or through the sale of capital stock to any person, if after any such transaction, the stockholders of Harrah's immediately prior to such transaction do not own at least 50% of the voting stock of the surviving or acquiring entity immediately after such transaction; or (h) by Harrah's or Rio, if there has been a breach of any representation, warranty, covenant or agreement on the part of the non-terminating party set forth in the Merger Agreement, which breach will cause the Harrah's Representation Bringdown Condition or the Harrah's Performance Condition (in the case of termination by Rio) or the Rio Representation Bringdown Condition or the Rio Performance Condition (in the case of termination by Harrah's) not to be satisfied. In the event of termination of the Merger Agreement as provided above, the Merger Agreement will immediately become void and there will be no liability or obligation on the part of Harrah's, Merger Sub or Rio, or their respective officers, directors, stockholders or Affiliates, except as provided below with respect to termination fees and expenses and except that such termination will not limit liability for a willful breach of the Merger Agreement; PROVIDED that the provisions described below with respect to termination fees 51 and expenses and the Confidentiality Agreements, dated June 18, 1998, between Rio and Harrah's will remain in full force and effect and survive any termination of the Merger Agreement. Except as set forth below, all fees and expenses incurred in connection with the Merger Agreement and the transactions contemplated hereby will be paid by the party incurring such expenses, whether or not the Merger is consummated. Rio will pay Harrah's a termination fee of $22.5 million via wire transfer of same-day funds on the date of the earliest to occur of the following events: (i) the termination of the Merger Agreement by Harrah's or Rio under the circumstances described in clause (d)(i) above, if an Acquisition Proposal involving Rio has been publicly announced prior to the meeting of Rio's stockholders and either a definitive agreement for a Rio Alternative Transaction is entered into, or a Rio Alternative Transaction is consummated, within twelve months of such termination; (ii) the termination of the Merger Agreement by Harrah's under the circumstances described in clause (e)(i) above; (iii) the termination of the Merger Agreement by Rio under the circumstances described in clause (f) above; or (iv) the termination of the Merger Agreement by Harrah's under the circumstances described in clause (h) above, PROVIDED that if such termination occurs solely on account of Rio's breach of a representation or warranty (and Rio has not otherwise breached any material covenant or agreement, in which case this proviso shall not apply), such termination fee shall be payable only if an Acquisition Proposal involving Rio shall have been publicly announced prior to such termination and either a definitive agreement for a Rio Alternative Transaction is entered into, or a Rio Alternative Transaction is consummated, within twelve months of such termination. Rio's payment of a termination fee as described above will be the sole and exclusive remedy of Harrah's against Rio and any of its subsidiaries and their respective directors, officers, employees, agents, advisors or other representatives with respect to the occurrences giving rise to such payment; PROVIDED that this limitation will not apply in the event of a willful breach of the Merger Agreement by Rio. A "Rio Alternative Transaction" means (i) a transaction pursuant to which any Third Party acquires more than 50% of the outstanding shares of Rio Common Stock pursuant to a tender offer or exchange offer or otherwise, (ii) a merger or other business combination involving Rio pursuant to which any Third Party (or the stockholders of a Third Party) acquires more than 50% of the outstanding shares of Rio Common Stock or the entity surviving such merger or business combination, or (iii) any other transaction pursuant to which any Third Party acquires control of assets (including for this purpose the outstanding equity securities of Subsidiaries of Rio, and the entity surviving any merger or business combination including any of them) of Rio having a fair market value (as determined in good faith by the Rio Board) equal to more than 50% of the fair market value of all the assets of Rio and its Subsidiaries, taken as a whole, immediately prior to such transaction. Harrah's shall pay Rio a termination fee of $22.5 million via wire transfer of same-day funds on the date of the earliest to occur of the following events: (i) the termination of the Merger Agreement by Harrah's or Rio under the circumstances described in clause (d)(ii) above, if an Acquisition Proposal involving Harrah's shall have been publicly announced prior to the meeting of Harrah's stockholders and either a definitive agreement for a Harrah's Alternative Transaction is entered into, or a Harrah's Alternative Transaction is consummated, within twelve months of such termination; (ii) the termination of the Merger Agreement by Rio under the circumstances described in clause (e)(ii) above; or (iii) the termination of the Merger Agreement by Rio under the circumstances described in clause (h) below, PROVIDED that if such termination occurs solely on account of Harrah's breach of a representation or warranty (and Harrah's has not otherwise breached any material covenant or agreement, in which case this proviso shall not apply), such termination fee shall be payable only if an Acquisition Proposal involving Harrah's shall have been publicly announced prior to such termination and either a definitive agreement for a Harrah's Alternative Transaction is entered into, or an Alternative Transaction is consummated, within twelve months of such termination. Harrah's payment of a termination fee as described above shall be the sole and exclusive remedy of Rio against Harrah's and any of its Subsidiaries and their respective directors, officers, employees, agents, advisors or other representatives with respect to the occurrences 52 giving rise to such payment; PROVIDED that this limitation shall not apply in the event of a willful breach of the Merger Agreement by Harrah's.

AMENDMENT AND WAIVER The Merger Agreement may be amended by the parties thereto, by action taken or authorized by their respective Boards of Directors, at any time before or after approval of the matters presented in connection with the Merger by the stockholders of Rio, but, after any such approval, no amendment may be made which by law requires further approval by such stockholders without such further approval. The Merger Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties. At any time prior to the Effective Time, the parties to the Merger Agreement, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other parties thereto, (ii) waive any inaccuracies in the representations and warranties contained therein or in any document delivered pursuant thereto and (iii) waive compliance with any of the agreements or conditions contained therein. Any agreement on the part of a party to the Merger Agreement to any such extension or waiver will be valid only if set forth in a written instrument signed on behalf of such party. STOCKHOLDER SUPPORT AGREEMENTS As an inducement and condition to the willingness of Harrah's and Rio to enter into the Merger Agreement, certain stockholders of Rio (each, a "Stockholder" and collectively, the "Stockholders") entered into the Stockholder Support Agreements. The Stockholders are James A. Barrett, Jr., the Barrett Family Revocable Living Trust, Barrett, Inc., Austi, LLC and Anthony A. Marnell II. Collectively, the Stockholders held, at the Record Date, approximately 16.6% of the combined voting power of the outstanding capital stock of Rio. In each Stockholder Support Agreement, each Stockholder has agreed, at the meeting of Rio's Stockholders to vote upon the Merger Agreement and the Merger or at any other meeting of the stockholders of Rio, however called, and in any action by written consent of the stockholders of Rio, to vote all of such Stockholder's shares of Rio Common Stock (i) in favor of adoption of the Merger Agreement and the approval of the Merger and the other transactions contemplated by the Merger Agreement, and (ii) in favor of any other matter necessary to the consummation of the transactions contemplated by the Merger Agreement and considered and voted upon by the stockholders of Rio (or any class thereof). Pursuant to the terms of each Stockholder Support Agreement, each Stockholder also has agreed that (a) it will not, nor will it authorize or permit any of its employees, agents and representatives to, directly or indirectly, initiate or solicit any inquiries or the making of any Acquisition Proposal and (b) it will notify Harrah's as soon as possible if any such inquiries or proposals are received by, any information or documents is requested from, or any negotiations or discussions are sought to be initiated or continued with, it or any of its affiliates. Each Stockholder Support Agreement will terminate upon the earliest to occur of (i) the Effective Time or (ii) any termination of the Merger Agreement in accordance with the terms thereof. 53 COMPARATIVE MARKET PRICES AND DIVIDENDS The following table sets forth, for the fiscal quarters indicated, the range of high and low sale prices of Harrah's Common Stock and Rio Common Stock on the NYSE.

See Notes to Unaudited Pro Forma Condensed Financial Statements. 58 HARRAH'S ENTERTAINMENT, INC. NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS Note 1--Historical financial information for Harrah's for the six months ended June 30, 1998 and the year ended December 31, 1997 has been derived from the Harrah's historical financial statements. Harrah's financial statements for the six month period ended June 30, 1998 include Showboat's operations after its June 1, 1998 acquisition by Harrah's. Note 2--The Showboat historical financial information for the year ended December 31, 1997 has been derived from Showboat's historical financial information. Showboat's historical financial results reflected in the Unaudited Pro Forma Condensed Statement of Income for the Six Months Ended June 30, 1998 include only the five months of Showboat's operations prior to its June 1, 1998 acquisition by Harrah's. Note 3--Following are brief descriptions of the pro forma adjustments to reflect Harrah's acquisition of Showboat. (a) Adjusts the historical statements of income to reflect the operating results of Showboat East Chicago as being accounted for under the equity method (rather than consolidated) and to remove the operating results of Showboat Las Vegas. Harrah's owns a 55% non-controlling interest in the partnership which owns and operates Showboat East Chicago. The agreements which govern the management of this partnership stipulate that certain actions require unanimous approval of all partners, or the consent of the minority partner, before such action can be taken. These actions include, among others, the approval of the annual operating budget, approval of the annual capital budget, decisions to buy or sell assets totaling more than $500,000 in any one calendar year and the incurrence of more than $500,000 of debt in any one calendar year. Given the significance of the issues requiring the concurrence of the minority partner, Harrah's has concluded that it does not have control of the partnership for accounting purposes and will account for this investment under the equity method of accounting. Showboat Las Vegas is being carried by Harrah's as an asset held for sale and, as such, is carried on Harrah's balance sheet at its estimated realizable value, net of estimated selling expenses and carrying costs through the expected date of sale. The net impact on income from continuing operations of the pro forma adjustments related to East Chicago is zero. The net impact of the adjustments related to Showboat Las Vegas is to increase income from continuing operations by $2.1 million for the six months ended June 30, 1998 and $3.5 million for the year ended December 31, 1997. (b) Reflects estimated expense for the amortization of the excess of the purchase price paid over the net book value of the assets acquired. Harrah's is currently in the process of allocating the purchase price among the tangible and intangible assets acquired and the liabilities assumed based on fair market values, as determined by appraisals, discounted cash flows, quoted market prices and estimates made by management. The purchase price allocation process is expected to be completed by the end of 1998. For purposes of these pro forma statements, it is assumed that the excess purchase price will be amortized over an average 30 year life for all tangible and intangible assets acquired. Upon completion of the purchase price allocation process, to the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired, such excess will be allocated to goodwill and amortized over 40 years. (c) Reflects adjustments for transaction costs expensed by Showboat in pre-transaction periods and estimated administrative costs savings to be realized as a result of merger efficiencies. (d) Reflects reduction in interest expense for the impact of Harrah's retirement of $218.6 million face amount of Showboat's 9 1/4% First Mortgage Bonds due 2008 and $117.9 million face amount of Showboat's Senior Subordinated Notes due 2009 using funds drawn under Harrah's revolving credit facility. See Note (f). 59 HARRAH'S ENTERTAINMENT, INC. NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS (CONTINUED) (e) Reflects additional interest expense, including amortization of related deferred finance charges, arising from the incremental borrowings incurred by Harrah's to fund the purchase of Showboat's outstanding common stock. See Note (f). (f) The funds required to fund the retirement of a portion of Showboat's outstanding debt (see Note (d)) and the purchase of Showboat's outstanding common stock (see Note (e)) were borrowed under Harrah's revolving credit facility, and the pro forma effects of such borrowing on interest expense have been computed at a historical average floating rate of 6.26% for the six months ended June 30, 1998, and 6.29% for the year ended December 31, 1997. Each 1/8 of a percent change in the floating rate on these borrowings would result in a change in interest expense of $1.1 million for the six months ended June 30, 1998, and $0.6 million for the year ended December 31, 1997. (g) Records the estimated tax effect of the pro forma adjustments, with the exception of the amortization of the unallocated purchase price, which is assumed to be nondeductible for tax purposes. Note 4--The Rio historical financial information for the six months ended June 30, 1998 and the year ended December 31, 1997 has been derived from Rio's historical financial information. Note 5--The following table sets forth the determination and preliminary allocation of the purchase price based on a market value of $19.83 per share of Harrah's Common Stock, which is the average of the quoted market price of Harrah's Common Stock for the period beginning three trading days before and ending three trading days after the Merger was announced.

(51.6) ------ $ 879.7 ------ ------
The final purchase price and its allocation will be based on independent appraisals, discounted cash flows, quoted market prices and estimates by management and is expected to be completed by June 30, 1999. Following are brief descriptions of the pro forma adjustments to the statements of income to reflect Harrah's acquisition of Rio. 60 HARRAH'S ENTERTAINMENT, INC. NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS (CONTINUED) (h) Adjusts depreciation expense due to the revaluation of acquired buildings and equipment resulting from the allocation of the purchase price of Rio. Depreciation expense is reduced $0.7 million for the six months ended June 30, 1998 and $1.3 million for the year ended December 31, 1997. (i) Reflects increase in expense due to amortization of goodwill arising from Harrah's purchase of Rio. Amortization expense is increased $2.1 million for the six months ended June 30, 1998 and $4.1 million for the year ended December 31, 1997. Goodwill is assumed to be amortized over a life of 40 years. (j) Records the impact on expenses of certain estimated operational efficiencies for functions which are expected to be eliminated or reduced as a result of the Merger. The elimination of duplicative corporate office and operational support functions is estimated to reduce other costs and expenses and corporate expense by $3.5 million for the six months ended June 30, 1998 and to reduce other costs and expenses and corporate expense by $7.0 million for the year ended December 31, 1997. (k) Reflects net reduction in interest expense for the impact of the Company's refinancing of $100.0 million face amount of Rio's 10 5/8% Senior Subordinated Notes due 2005, $125.0 million face amount of Rio's 9 1/2% Senior Subordinated Notes due 2007 and Rio's revolving credit facility. The funds required to fund the refinancing of Rio's outstanding debt is assumed to be provided by the issuance by Harrah's of new senior notes. The pro forma effects on interest expense have been computed at an assumed rate of 7.25% for both the six months ended June 30, 1998 and for the year ended December 31, 1997. Each 1/8 of a percent change in the floating rate on these borrowings would result in a change in interest expense of $0.2 million for the six months ended June 30, 1998, and $0.4 million for the year ended December 31, 1997. (l) Records the estimated tax effect of these pro forma adjustments, with the exception of the amortization of goodwill, which is assumed to be nondeductible for tax purposes. (m) Pro forma income from continuing operations per share is computed on the basis of the combined weighted average number of shares of Harrah's Common Stock and Harrah's Common Stock equivalents after giving effect to the issuance of shares to consummate the Merger. Note 6--Following are brief descriptions of the pro forma adjustments to the balance sheet to reflect the acquisition by Harrah's of Rio. (n) Reflects the net increase in the carrying value of Rio's land, buildings and equipment to adjust those assets to their estimated fair market value. (o) Reflects as goodwill the excess purchase price over fair value of net tangible assets acquired and liabilities assumed. (p) Reduces other assets to reflect deferred financing costs of Rio not valued due to the adjustment of debt to estimated fair market value. (q) Reflects additional deferred finance charges arising from the assumed issuance by Harrah's of new senior notes. (r) Records as current liabilities the accrual of severance and direct merger costs of Harrah's and Rio. 61 HARRAH'S ENTERTAINMENT, INC. NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS (CONTINUED) (s) Reflects the net adjustment to long-term debt to reflect the Rio debt at its estimated fair market value and the refinancing of such debt by Harrah's, which is expected to occur subsequent to the closing of the Merger. (t) Records the deferred tax effect of the pro forma balance sheet adjustments, primarily related to land, buildings and equipment, net of the estimated tax benefit arising from the assumed refinancing of Rio debt. (u) The net increase in stockholders' equity reflects: (i) the issuance of one share of Harrah's Common Stock for each share of Rio Common Stock outstanding and (ii) the elimination of Rio's historical retained earnings. 62 PRO FORMA SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT OF HARRAH'S The following table sets forth certain pro forma information as to the number of shares of Harrah's Common Stock that will be beneficially owned by (i) each person known by Harrah's to be the beneficial owner of more than 5% of any of Harrah's voting securities, (ii) each director of Harrah's, (iii) the Chief Executive Officer and the other highly compensated executive officers of Harrah's and (iv) Harrah's executive officers and directors as a group assuming the Merger had been consummated on October 5, 1998.

GENERAL The authorized capital stock of Harrah's, upon completion of the Merger, will consist of 360,000,000 shares of Harrah's Common Stock, 150,000 shares of preferred stock, par value of $100.00 per share ("Harrah's Preferred Stock"), and 5,000,000 authorized shares of special stock, par value $1.125 per share ("Harrah's Special Stock"). Based upon the number of shares of Harrah's Common Stock and Rio Common Stock outstanding on the record date of the Harrah's Special Meeting and the record date of the Rio Special Meeting, respectively, it is anticipated that approximately 126,280,764 shares of Harrah's Common Stock and no shares of Harrah's Preferred Stock or Harrah's Special Stock will be issued and outstanding immediately after the completion of the Merger. HARRAH'S COMMON STOCK Each share of Harrah's Common Stock entitles the holder to one vote on matters submitted to a vote of the stockholders. Under the Harrah's Certificate, the Harrah's Board is classified into three classes of directors which serve staggered three year terms. The holders of Harrah's Common Stock are not entitled to cumulate votes for the election of directors. The holders of Harrah's Common Stock are entitled to receive ratably a share of any dividends declared by the Harrah's Board with respect to Harrah's Common Stock. In the event of liquidation, dissolution or winding up of Harrah's, holders of Harrah's Common Stock have the right to a ratable portion of the assets remaining after the payment of liabilities and liquidation preferences of any outstanding shares of Harrah's Preferred Stock. The holders of Harrah's Common Stock have no preemptive rights or rights to convert their Harrah's Common Stock into other securities. All outstanding shares of Harrah's Common Stock immediately following completion of the Merger will be fully paid and nonassessable. The rights of the holders of Harrah's Common Stock will be subject to, and may be adversely affected by, the rights of the holders of Harrah's Preferred Stock, if any. HARRAH'S PREFERRED STOCK Harrah's Certificate provides that Harrah's Preferred Stock may be issued from time to time in one or more series. The Harrah's Board has the authority to fix and determine the number of shares constituting each such series and the relative rights, preferences, privileges and immunities, if any, and any qualifications, limitations or restrictions thereof, of the shares thereof, including the authority to fix and determine the dividend rights, dividend rates, conversion rights, voting rights and terms of redemption (including sinking fund provisions), redemption prices and liquidation preferences of any wholly unissued series of Harrah's Preferred Stock and to increase or decrease the number of shares of any outstanding series, without further vote or action by Harrah's stockholders. No Harrah's Preferred Stock is outstanding, no Harrah's Preferred Stock will be issued in connection with the Merger, and Harrah's has no present plans to issue any shares of Harrah's Preferred Stock. HARRAH'S SPECIAL STOCK The Harrah's Board has the authority, without further action by stockholders, to determine the rights, preferences and privileges of the unissued Harrah's Special Stock. Provisions could be included in the shares of Harrah's Special Stock, such as extraordinary voting, dividend, redemption or conversion rights, which could discourage an unsolicited tender offer or takeover proposal. 65 SPECIAL STOCK PURCHASE RIGHTS The Harrah's Board has authorized that one Special Stock purchase right (a "Right") be attached to each outstanding share of Harrah's Common Stock. These Rights are exercisable only if a person or group acquires 15% or more of the Harrah's Common Stock or announces a tender offer for 15% or more of the Harrah's Common Stock. Each Right entitles stockholders to buy one two-hundredth of a share (a "Unit") of Series A Special Stock (the "Series A Stock") at a purchase price of $130.00 per Unit, subject to certain anti-dilution adjustments (the "Purchase Price"). If a person acquires 15% of more of the outstanding Harrah's Common Stock, each Right entitles its holder to purchase Harrah's Common Stock having a market value at that time of twice the Right's exercise price. Under certain conditions, each Right entitles its holder to purchase stock of an acquiring company at a discount. Rights held by the 15% owner will become void. The Rights will expire on October 5, 2006, unless earlier redeemed by the Harrah's Board at $0.01 per Right. The issuance of the Rights to purchase shares of Harrah's Special Stock will have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire Harrah's on terms not approved by the Harrah's Board. The Rights should not interfere with any merger or other business combination approved by the Harrah's Board prior to the first date of public announcement that a person or group has acquired beneficial ownership of 15% or more of the Harrah's Common Stock, as the Rights will be redeemable by Harrah's at $0.01 per Right prior to such time. PROHIBITED BUSINESS TRANSACTIONS As a corporation organized under the laws of the State of Delaware, Harrah's is subject to Section 203 of the Delaware General Corporation Law (the "DGCL"), which restricts certain business combinations between Harrah's and an "interested stockholder" (in general, a stockholder owning 15% or more of the outstanding voting stock of Harrah's) or such stockholder's affiliates or associates for a period of three years following the date on which the stockholder becomes an "interested stockholder." The restrictions do not apply if: (i) prior to an interested stockholder becoming such, the Harrah's Board approves either the business combination or the transaction by which such person became an interested stockholder; (ii) upon consummation of the transaction, the interested stockholder owns at least 85% of the voting stock of Harrah's outstanding at the time the transaction commenced (excluding shares owned by certain employee stock plans and persons who are both directors and officers of Harrah's); or (iii) at or subsequent to the time an interested stockholder becomes such, the business combination is both approved by the Harrah's Board and authorized at an annual or special meeting of Harrah's stockholder by the affirmative vote of at least two-thirds of the outstanding voting stock of Harrah's not owned by the interested stockholder. The Harrah's Certificate also prohibits business combinations with "Interested Stockholders" and defines them to be anyone who is or intends to become the beneficial owner of 10% or more of the voting stock of Harrah's. Unless approved by a majority of Continuing Directors (as defined in the Harrah's Certificate) or the Interested Stockholder satisfies a number of criteria relating to, among other things, the consideration to be received by Harrah's stockholders and the public disclosure of the business combination, a proposed business combination with an Interested Stockholder requires the affirmative vote of 75% of all the votes entitled to be cast by holders of Harrah's voting stock and not less than a majority of votes entitled to be cast by holders of Harrah's voting stock, excluding the votes of the interested stockholder. REGISTRAR AND TRANSFER AGENT The Registrar and Transfer Agent of Harrah's is The Bank of New York. 66 COMPARISON OF RIGHTS OF HOLDERS OF HARRAH'S COMMON STOCK AND RIO COMMON STOCK BEFORE AND AFTER THE MERGER The following is a summary of the material differences between the rights of holders of Rio Common Stock before the Merger and the rights of holders of Harrah's Common Stock before and after the Merger. Harrah's is incorporated under the laws of Delaware, and Rio is incorporated under the laws of Nevada. If the Merger is consummated, the holders of Rio Common Stock, whose rights are currently governed by the general corporation laws of Nevada, the Rio Amended and Restated Articles of Incorporation (the "Rio Articles") and the Rio Amended and Restated Bylaws (the "Rio Bylaws"), will become holders of Harrah's Common Stock, whose rights are governed by the DGCL, the Harrah's Certificate, and the Harrah's Bylaws. The general corporation and merger laws of Nevada are codified in Chapter 78 and Chapter 92A of the NRS. The NRS differs from the DGCL in many respects. The following summary sets forth all material differences that should be considered by Rio's stockholders. The following summary does not purport to be a complete statement of the differences between the NRS and the DGCL, which are too numerous to list in their entirety. SIZE AND CLASSIFICATION OF THE BOARD OF DIRECTORS Section 141(b) of the DGCL provides that the board of directors shall consist of one or more members. The number of directors shall be fixed by, or in the manner provided in, the bylaws, unless the certificate of incorporation fixes the number of directors, in which case a change in the number of directors shall be made only by amendment of the certificate of incorporation. Pursuant to Section 141(d) of the DGCL, the directors of any Delaware corporation may, by the certificate of incorporation, by an initial bylaw or by a bylaw adopted by a vote of the stockholders, be divided into one, two or three classes. Harrah's Board is divided into three staggered fixed classes, with each class elected in separate years for three-year terms. The size of Harrah's Board currently is fixed at twelve members, with two vacancies. Section 78.115 of the NRS provides that a corporation must have at least one director, and may provide in its articles of incorporation or its bylaws for a fixed number of directors or a variable number of directors within a fixed maximum and minimum, and for the manner in which the number of directors may be increased or decreased. Section 78.330 of the NRS provides that the articles of incorporation or the bylaws may provide for a classified board of directors, but at least one-fourth of the directors must be elected annually. Rio's Board is classified into two staggered classes, with each class elected in separate years for two-year terms. The size of Rio's Board currently is fixed at six members. DUTIES OF DIRECTORS Section 78.138 of the NRS allows directors and officers of a corporation to consider a variety of non-stockholder interests in discharging their duties to the corporation. The non-stockholder interests include the interests of the corporation's employees, suppliers, creditors and customers, the economy of the state and nation, the interest of the community and of society, and the long-term as well as short-term interests of the corporation and its stockholders. There is no corresponding provision in the DGCL. However, Delaware courts, in certain instances, have indicated that directors may consider various constituencies provided there exists some rationally related benefit to the stockholders. REMOVAL OF DIRECTORS Section 141(k) of the DGCL provides that any director or the entire board of directors may generally be removed with or without cause by a majority stockholder vote. However, a director of a corporation with a classified board of directors may be removed only for cause unless the certificate of incorporation otherwise provides. The Harrah's Bylaws provide that, unless otherwise restricted by the Harrah's Certificate or by law, any director or the entire Harrah's Board may be removed, either with or without 67 cause from the Harrah's Board at any meeting of stockholders by a majority of the stock represented and entitled to vote at such meeting. Under Section 78.335 of the NRS, any director may be removed from office by a two-thirds stockholder vote, or by the vote of such larger percentage of shares as may be provided in the articles of incorporation. A director elected by a voting group, unless otherwise provided in the articles of incorporation, may only be removed by a vote of two-thirds of the members of the group, or by the vote of such larger percentage of the group as may be provided in the articles of incorporation for the removal of directors. The Rio Bylaws provide that any director of the Rio Board may be removed by holders of two-thirds of the outstanding Rio Common Stock either at a meeting called for such purpose or by filing a written statement to that effect with the Secretary of Rio. NEWLY CREATED DIRECTORSHIPS AND VACANCIES Under Section 223 of the DGCL, unless the certificate of incorporation or the bylaws of a corporation provide otherwise, a majority vote of the directors then in office may fill vacancies and newly created directorships, even if the number of current directors is less than a quorum or only one director remains. If the directors filling an open slot on the board of directors constitute less than a majority of the whole board of directors (as measured before an increase in the size of the board of directors), the Delaware Court of Chancery may, upon application of stockholders holding at least ten percent (10%) of the outstanding voting shares, summarily order an election to fill the open slots or replace directors chosen by the directors then in office. Unless otherwise provided in the certificate of incorporation or bylaws, when one or more directors resign effective at a future date, a majority of directors then in office, including those who have so resigned, may vote to fill the vacancy. Similarly, under Section 78.335 of the NRS, vacancies, including those caused by an increase in the number of directors, may be filled by a majority of the remaining directors, though less than a quorum, unless the articles of incorporation provide otherwise. The Rio Articles do not provide otherwise. If a director gives notice of his or her resignation to the board of directors, to become effective at a future date, the board of directors may fill the vacancy to take effect when the resignation becomes effective, with the director so appointed to hold office during the remainder of the term of office of the resigning director. However, vacancies created by the removal of a director may only be filled by vote of the stockholders. LIMITATION ON DIRECTORS' LIABILITY Section 102(b)(7) of the DGCL allows a corporation, through its certificate of incorporation, to limit or eliminate the personal liability of directors to the corporation and its stockholders for monetary damages for breach of fiduciary duty. However, this provision excludes any limitation on liability for (i) any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) act or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) willful or negligent violation of the laws governing the payment of dividends or the purchase or redemption of stock or (iv) any transaction from which the director derives an improper personal benefit. The Harrah's Certificate limits the liability of directors in the above manner. Section 78.037 of the NRS allows a corporation, through its articles of incorporation, to limit or eliminate the personal liability of directors and officers to the corporation and its stockholders for damages for breach of fiduciary duty. However, this provision excludes any limitation on liability for (i) acts or omissions which involve intentional misconduct, fraud or a knowing violation of law or (ii) the payment of distributions in violation of Section 78.300 of the NRS. The Rio Articles limit the liability of directors in the above manner. 68 INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 145 of the DGCL and Section 78.751 of the NRS both provide that a corporation may indemnify any person made a party or threatened to be made a party to any type of proceeding (other than certain actions by or in right of the corporation) because he or she is or was a director, officer, employee or agent of the corporation or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such proceeding if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation; or in a criminal proceeding, if he or she had no reasonable cause to believe his or her conduct was unlawful. Expenses incurred by an officer or director (or other employees or agents as deemed appropriate by the board of directors) in defending civil or criminal proceedings may be paid by the corporation in advance of the final disposition of such proceeding upon receipt of an undertaking by or on behalf of such person to repay such amount if it is ultimately determined that such person is not entitled to be indemnified by the corporation. To indemnify a party, the corporation must determine that the party met the applicable standards of conduct. The Harrah's Certificate, the Rio Articles and Rio Bylaws provide for indemnification of directors and officers substantially in the manner described above. LOANS TO DIRECTORS Section 143 of the DGCL allows a corporation to lend money to or guarantee an obligation of or otherwise assist an officer or employee, including one who acts as a director, if the loan, guaranty or other assistance is reasonably expected to benefit the corporation. Such loan, guaranty or other assistance may be provided without stockholder approval. The NRS contains no corresponding provision. DIVIDENDS Subject to additional restrictions in a corporation's certificate of incorporation, Section 170 of the DGCL allows the board of directors of a Delaware corporation to pay dividends out of surplus or, if there is no surplus, out of its net profits for the fiscal year in which the dividend is declared or the preceding fiscal year. Section 78.288 of the NRS allows a board of directors to make distributions to stockholders, unless otherwise provided in the articles of incorporation. However, no distribution may be made if it would cause (i) the corporation to be unable to pay its debts as they become due in the normal course of business or (ii) expect as otherwise specifically allowed by the articles of incorporation, the corporation's total assets to be less than the sum of its total liabilities plus the amount that would be needed, if the corporation were to be dissolved at the time of the distribution, to satisfy the preferential stockholders whose rights are superior to those receiving the distribution. ACTION BY STOCKHOLDERS THROUGH WRITTEN CONSENT Under Section 228(a) of the DGCL, unless otherwise provided in a corporation's certificate of incorporation, any action required to be taken at an annual or special meeting of the stockholders may be taken in the absence of a meeting, without prior notice and without a vote. Such action may be taken by the written consent of stockholders in lieu of a meeting setting forth the action so taken and signed by the holders of outstanding stock representing the number of shares necessary to take such action at a meeting at which all shares entitled to vote were present and voted. The Harrah's Certificate prohibits stockholders from taking any action by written consent. Under Section 78.320 of the NRS, unless otherwise provided in a corporation's articles of incorporation or bylaws, any action required or permitted to be taken at a meeting of stockholders may be taken without a meeting if a written consent thereto is signed by stockholders holding at least a majority of the voting power, except that if a different proportion of voting power is required for such an action at a 69 meeting, then that proportion of written consents is required. The Rio Bylaws provide that any action that may be taken by the vote of stockholders at a meeting may be taken without a meeting if authorized by the written consent of stockholders holding at least 50% of the voting power, unless the NRS or provisions of the Rio Articles or the Rio Bylaws require a greater percentage of voting power to authorize such action in which case a greater percentage of voting power shall be required. SPECIAL MEETING OF STOCKHOLDERS Under Section 211(d) of the DGCL, a special meeting of stockholders may be called by the board of directors and by such other person or persons as may be authorized to do so by the corporation's certificate of incorporation or bylaws. The Harrah's Certificate provides that a special meeting of stockholders may only be called by a majority of the entire Harrah's Board or by the Chairman or President of Harrah's. Under Section 78.310 of the NRS, meetings may be held in the manner provided by the bylaws of the corporation. The Rio Bylaws provide that a special meeting of stockholders may be called by the President or Secretary of Rio, by resolution of the Rio Board or at the written request of one or more stockholders owning in the aggregate entitled to vote not less than 50% of the votes at such a meeting. CUMULATIVE VOTING Both Section 214 of the DGCL and Section 78.360 of the NRS allow a corporation to provide for cumulative voting in the certificate of incorporation or the articles of incorporation. However, neither the Rio Articles nor the Harrah's Certificate provide for cumulative voting. NECESSARY VOTE TO EFFECT MERGER (NOT INVOLVING INTERESTED STOCKHOLDERS) The DGCL requires a majority vote of the shares entitled to vote in order to effectuate a merger between two (2) Delaware corporations (Section 251(c)) or between a Delaware corporation and a corporation organized under the laws of another state (a "foreign corporation") (Section 252(c)). However, unless required by the certificate of incorporation, Sections 251(f) and 252(e) do not require a vote of the stockholders of a constituent corporation surviving the merger if (i) the merger agreement does not amend that corporation's certificate of incorporation, (ii) each share of that corporation's stock outstanding before the effective date of the merger is identical to an outstanding or treasury share of the surviving corporation after the merger and (iii) in the event the merger plan provides for the issuance of common stock or securities convertible into common stock by the surviving corporation, the common stock issued and the common stock issuable upon conversion of the issued securities do not exceed twenty percent (20%) of the shares outstanding immediately before the effective date of the merger. Section 92A.120 of the NRS requires the a majority of shares entitled to vote in order to effect any merger. However, the articles of incorporation or the board of directors may provide for a greater vote under some circumstances. In addition, Section 92A.130 of the NRS provides that the vote of a majority of the shares entitles to vote is not required under substantially the same conditions as are specified in Sections 251(f) and 252(e) of the DGCL. BUSINESS COMBINATIONS INVOLVING INTERESTED STOCKHOLDERS As described above, Section 203 of the DGCL restricts certain business combinations between a Delaware corporation and an "interested stockholder" (in general, a stockholder owning 15% or more of the outstanding voting stock of such corporation) or such stockholder's affiliates or associates for a period of three years following the date on which the stockholder becomes an "interested stockholder." The restrictions do not apply if: (i) prior to an interested stockholder becoming such, the corporation's board of directors approves either the business combination or the transaction by which such person became an interested stockholder; (ii) upon consummation of the transaction, the interested stockholder owns at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding 70 shares owned by certain employee stock plans and persons who are both directors and officers of such corporation); or (iii) at or subsequent to the time an interested stockholder becomes such, the business combination is both approved by the corporation's board of directors and authorized at an annual or special meeting of the corporation's stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock of the corporation not owned by the interested stockholder. Certain provisions of the Harrah's Certificate also establish special requirements with respect to certain business combinations (including, without limitation, mergers, consolidations, share exchanges, or, in certain circumstances, asset transfers or issuances or reclassifications of equity securities) between Harrah's and any interested stockholder or affiliate of an interested stockholder. Pursuant to the Harrah's Certificate, any such business combination would require the affirmative vote of (a) not less than 75% of the votes entitled to be cast by holders of Harrah's Common Stock and (b) not less than 50% of the votes entitled to be cast by holders of Harrah's Common Stock, excluding the votes of such interested stockholder. The Harrah's Certificate defines an interested stockholder as any person who (a) is, or has announced or publicly disclosed a plan or intention to become, the beneficial owner of Harrah's Common Stock representing ten percent (10%) or more of the votes entitled to be cast by holders of Harrah's Common Stock, or (b) is an affiliate or associate of Harrah's and at any time within the two-year period immediately prior to the date in question was the beneficial owner of Harrah's Common Stock representing ten percent (10%) or more of the votes entitled to be cast by holders of Harrah's Common Stock. These provisions of the Harrah's Certificate do not apply, however, to those business combinations involving consideration satisfying certain fair market value thresholds and those business combinations that have been approved by a majority of directors of the Harrah's Board who are neither an affiliate nor an associate nor a representative of the interested stockholder. Similar to Section 203 of the DGCL, Sections 78.411 to 78.444 of the NRS, inclusive, restrict the ability of a resident domestic corporation to engage in any combination with an interested stockholder for three (3) years after the interested stockholder's date of acquiring the shares that cause such stockholder to become an interested stockholder unless the combination or the purchase of shares by the interested stockholder on the interested stockholder's date of acquiring the shares that cause such stockholder to become an interested stockholder is approved by the board of directors of the resident domestic corporation before that date. If the combination was not previously approved, the interested stockholder may effect a combination after the three-year period only if such stockholder receives approval from a majority of the disinterested shares or the offer meets certain fair price criteria. For purposes of the foregoing provisions, "resident domestic corporation" means a Nevada corporation that has 200 or more stockholders and "interested stockholder" means any person, other than the resident domestic corporation or its subsidiaries, who is (a) the beneficial owner, directly or indirectly, of ten percent (10%) or more of the voting power of the outstanding voting shares of the resident domestic corporation or (b) an affiliate or associate of the resident domestic corporation and at any time within three years immediately before the date in question was the beneficial owner, directly or indirectly, of ten percent (10%) or more of the voting power of the outstanding shares of the resident domestic corporation. The above provisions do not apply to any combination involving a resident domestic corporation (i) whose original articles of incorporation expressly elect not to be governed by Sections 78.411 to 78.444 of the NRS, inclusive, (ii) which does not, as of the date of acquiring shares, have a class of voting shares registered with the SEC under Section 12 of the Securities Act, unless the corporation's articles of incorporation provide otherwise, (iii) whose articles of incorporation were amended to provide that the corporation is subject to the above provisions and which did not have a class of voting shares registered with the SEC under Section 12 of the Securities Act on the effective date of such amendment, if the combination is with an interested stockholder whose date of acquiring shares is before the effective date of such amendment or (iv) that amends its articles of incorporation, approved by a majority of the disinterested shares, to expressly elect not to be governed by Sections 78.411 to 78.444 of the NRS, inclusive. Such an amendment, however, would not become effective until eighteen (18) months after its passage and would apply only to stock acquisitions occurring after the 71 effective date of the amendment. The Rio Articles do not exempt Rio from the restrictions imposed by such provisions of the NRS. CONTROL SHARE ACQUISITIONS Under the NRS, an "acquiring person" who acquires a "controlling interest" in an "issuing corporation" may not exercise voting rights on any "control shares" unless such voting rights are conferred by a majority vote of the disinterested stockholders of the issuing corporation at a special meeting of such stockholders held upon the request and at the expense of the acquiring person. In the event that the control shares are accorded full voting rights and the acquiring person acquires control shares with a majority or more of all the voting power, any stockholder, other than the acquiring person, who does not vote in favor of authorizing voting rights for the control shares is entitled to demand payment for the fair value of such person's shares, and the corporation must comply with the demand. For purposes of the above provisions, "acquiring person" means (subject to certain exceptions) any person who, individually or in association with others, acquires or offers to acquire, directly or indirectly, a controlling interest in an issuing corporation. "Controlling interest" means the ownership of outstanding voting shares of an issuing corporation sufficient to enable the acquiring person, individually or in association with others, directly or indirectly, to exercise (i) one-fifth or more but less than one-third, (ii) one-third or more but less than a majority, (iii) a majority or more of the voting power of the issuing corporation in the election of directors, and voting rights must be conferred by a majority of the disinterested stockholders as each threshold is reached and/or exceeded. "Control shares" means those outstanding voting shares of an issuing corporation that an acquiring person acquires or offers to acquire in an acquisition or within 90 days immediately preceding the date when the acquiring person became an acquiring person. "Issuing corporation" means a corporation that is organized in Nevada, has 200 or more stockholders, at least 100 of whom are stockholders of record and residents of Nevada, and does business in Nevada directly or through an affiliated corporation. The above provisions do not apply if the articles of incorporation or bylaws of the corporation in effect on the tenth day following the acquisition of a controlling interest by an acquiring person provide that such provisions do not apply. The Rio Articles and the Rio Bylaws do not exclude Rio from the restrictions imposed by such provisions. The DGCL does not contain an analogous "control share acquisition" statute. APPRAISAL RIGHTS; DISSENTERS' RIGHTS Both Section 262 of the DGCL and Sections 92A.380 and 92A.390 of the NRS provide that stockholders have the right, in some circumstances, to dissent from certain corporate reorganizations and to instead demand payment of the fair cash value of their shares. Unless a corporation's certificate of incorporation or articles of incorporation provides otherwise, dissenters do not have rights of appraisal with respect to (i) a merger by a corporation, the shares of which are either listed on a national securities exchange or held by more than 2,000 stockholders, if the stockholders receive cash (in the case of the NRS), shares in the surviving corporation, shares of another corporation that are publicly listed or held by more than 2,000 stockholders, cash in lieu of fractional shares or any combination of the above or (ii) stockholders of a corporation surviving a merger if no vote of the stockholders of the surviving corporation is required to approve the merger. The Rio Articles and Harrah's Certificate have no provisions regarding appraisal or dissenters' rights and Rio stockholders will not have appraisal or dissenters' rights in connection with the Merger. REDEEMABLE SHARES Section 151(b) of the DGCL provides that a Delaware corporation may make any class of stock subject to redemption at the option of the corporation or at the option of the holders of such stock or upon the happening of a specified event, provided that at the time of such redemption the corporation has at least one class of voting stock which is not subject to redemption. Under Section 151(b)(2) of the DGCL, 72 however, Harrah's is not subject to the proviso in the foregoing sentence because of its dependence on governmental licenses to conduct its business. The Harrah's Certificate provides that all shares of Harrah's capital stock may be redeemed by action of the Harrah's Board if any holder of such shares is found to be unsuitable for gaming regulatory reasons or such action is needed to prevent the loss of, or secure the reinstatement of, any gaming license of Harrah's or its affiliates required to conduct Harrah's business. Section 78.196(2)(b)(1) of the NRS provides that the articles of incorporation or a resolution of the board of directors may authorize one or more classes of stock that are redeemable or convertible at the option of the corporation, the stockholders or another person or upon the occurrence of a designated event. WARRANTS OR OPTIONS Under Section 157 of the DGCL, rights or options to purchase shares of any class of stock may be authorized by a corporation's board of directors subject to the provisions of the certificate of incorporation. The terms of such rights or options must be fixed and stated in the certificate of incorporation or in a resolution or resolutions adopted by the board of directors. Under Section 78.200 of the NRS, a corporation may create and issue rights or options entitling the holders thereof to purchase from the corporation shares of its stock of any class or classes. The terms of such rights or options must be fixed and stated in the articles of incorporation or in a resolution or resolutions adopted by the board of directors. PREEMPTIVE RIGHTS Under Section 102(b)(3) of the DGCL and Section 78.267 of the NRS (applicable only to corporations organized in the State of Nevada on or after October 1, 1991), absent an express provision in a corporation's certificate or articles of incorporation, a stockholder does not, by operation of law, possess preemptive rights to subscribe to an additional issue of stock. If a corporation is organized in the State of Nevada before October 1, 1991, Section 78.265 of the NRS provides that preemptive rights exist unless the corporation elects to opt out of such rights in its articles of incorporation. Neither the Rio Articles nor the Harrah's Certificate expressly grants stockholders any preemptive rights. AMENDMENT OF ARTICLES OF INCORPORATION AND BYLAWS Section 242 of the DGCL and Sections 78.385 and 78.390 of the NRS permit a corporation to amend its certificate or articles of incorporation in any respect provided the amendment contains only provisions that would be lawful in an original certificate of incorporation filed at the time of amendment. For a corporation that has received payment for any of its capital stock to amend its certificate of incorporation, the corporation's board of directors must adopt a resolution presenting the proposed amendment. In addition, a majority of the shares entitled to vote, as well as a majority of shares by class of each class entitled to vote, must approve the amendment to make it effective. When the substantial rights of a class of shares will be affected by an amendment, the holders of those shares are entitled to vote as a class even if the shares are non-voting shares. When only one or more series in a class of shares, and not the entire class, will be adversely affected by an amendment, only the affected series may vote as a class. Under Section 242(b)(2) of the DGCL, the right to vote as a class may be limited in certain circumstances. Any provision in the certificate of incorporation which requires a greater vote than required by law cannot be amended or repealed except by such greater vote. Section 242(c) of the DGCL provides that, in its resolution proposing an amendment, the board of directors may insert a provision allowing the board of directors to abandon the amendment, without concurrence by stockholders, after the amendment has received stockholder approval but before its filing with the Secretary of State. The Harrah's Certificate provides that Harrah's has reserved the right to amend, alter, change or repeal any provision of the Harrah's Certificate, in the manner now or thereafter prescribed by statute, and that all rights conferred 73 upon stockholders are granted subject to this reservation. The Rio Articles provide that Rio may amend, alter, change or repeal any provision of the Rio Articles except Article VI, in the manner prescribed by statute, the Rio Articles or the Rio Bylaws. Section 109 of the DGCL provides that the power to adopt, amend or repeal the bylaws rests with the stockholders entitled to vote, although the certificate of incorporation may confer the power to adopt, amend or repeal the bylaws upon the board of directors. Section 109 further provides that the fact that the certificate of incorporation confers such power upon the board of directors neither limits nor divests the stockholders of the power to adopt, amend or repeal the bylaws. The Harrah's Certificate provide that the Harrah's Bylaws may be amended by a majority vote of the entire Harrah's Board or by the affirmative vote of at least 75% of the holders of Harrah's Common Stock. Section 78.120 of the NRS, on the other hand, provides that, subject to the bylaws, if any, adopted by the stockholders, the directors may make the bylaws of the corporation. The Rio Articles and the Rio Bylaws provide that the Rio Bylaws may be amended by a majority vote of the entire Rio Board or by the affirmative vote of not less than a majority of the holders of Rio Common Stock. INSPECTION OF BOOKS AND RECORDS Section 220 of the DGCL entitles any stockholder of record of a corporation, in person or by an agent, upon written demand under oath stating the purpose thereof, to inspect during usual business hours, for any proper purpose, the corporation's stock ledger, a list of its stockholders and its other books and records, and to make copies or extracts therefrom. A proper purpose means a purpose reasonably related to such person's interest as a stockholder. Section 78.105 of the NRS entitles any person who has been a stockholder of record of a corporation for at least six (6) months, or any person holding or representing at least five percent (5%) of its outstanding shares, upon at least five (5) days' written demand, to inspect, in person or by an agent, during usual business hours, its stock ledger and to make extracts therefrom. Pursuant to Section 78.257 of the NRS, only stockholders of record who own or represent at least fifteen percent (15%) of a corporation's shares have the right, upon at least five (5) days' written demand, to inspect, in person or by an agent, during normal business hours, the books of account and financial records of the corporation, to make extracts therefrom and to conduct an audit of such records. However, Section 78.257 of the NRS does not apply to (a) any corporation listed and traded on any recognized stock exchange and (b) any corporation that furnishes to its stockholders a detailed, annual financial statement. 74 STOCKHOLDER PROPOSALS Stockholder proposals for inclusion in proxy material for Harrah's 1999 Annual Meeting of Stockholders must be submitted to the Secretary of Harrah's in writing so as to be received at the executive offices of Harrah's by November 13, 1998. Such proposals must also meet the other requirements of the rules of the SEC relating to stockholders' proposals and satisfy the notice procedures for stockholder proposals set forth in the Harrah's Bylaws. The Harrah's Bylaws require that for business to be properly brought before an annual meeting by a stockholder, the stockholder must have given timely notice thereof, containing the information required by the Harrah's Bylaws and in writing, to the Secretary of Harrah's. To be timely, a stockholder's notice containing the information required by the Harrah's Bylaws must be delivered to or mailed and received at the principal executive offices of Harrah's not less than sixty days nor more than ninety days prior to the meeting; provided, however, that in the event that less than seventy days notice or prior public disclosure of the date of the annual meeting is given or made to stockholders, notice by a stockholder, to be timely, must be received no later than the close of business on the tenth day following the day on which such notice of the date of the annual meeting was mailed or such public disclosure was made, whichever occurs first. Due to the contemplated consummation of the Merger, Rio does not currently expect to hold a 1999 Annual Meeting of Stockholders, as Rio Common Stock will not be publicly traded after the Merger. If the Merger is not consummated and such a meeting is held, stockholder proposals for inclusion in proxy materials for such meeting must be submitted to the Secretary of Rio in writing so as to be received at the executive offices of Rio by November 2, 1998. Such proposals must also meet the other requirements of the rules of the SEC relating to stockholders' proposals and satisfy the notice procedures for stockholder proposals set forth in the Rio Bylaws. LEGAL MATTERS The validity of the shares of Harrah's Common Stock to be issued in connection with the Merger will be passed upon by Latham & Watkins, Los Angeles, California. EXPERTS The consolidated financial statements of both Harrah's and Rio incorporated by reference into this Joint Proxy Statement/Prospectus have been audited by Arthur Andersen LLP, independent certified public accountants, as indicated in their reports with respect thereto, and are incorporated by reference herein in reliance upon the authority of said firm as experts in giving said reports.

A-v AGREEMENT AND PLAN OF MERGER AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of August 9, 1998, and as amended as of September 4, 1998, by and among HARRAH'S ENTERTAINMENT, INC., a Delaware corporation ("Harrah's"), HEI ACQUISITION CORP. III, a Nevada corporation and a direct wholly-owned subsidiary of Harrah's ("Merger Sub"), and RIO HOTEL & CASINO, INC., a Nevada corporation ("Rio"). WHEREAS, the Board of Directors of Rio has determined that the merger of Merger Sub with and into Rio, upon the terms and subject to the conditions set forth in this Agreement (the "Merger"), is fair to, and in the best interests of, Rio and its stockholders; WHEREAS, the Boards of Directors of Harrah's and Merger Sub have determined that the Merger is in the best interests of Harrah's and Merger Sub and their respective stockholders; WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a reorganization described in Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"); WHEREAS, the Boards of Directors of Harrah's, Merger Sub and Rio have each approved and adopted this agreement and approved the Merger and the other transactions contemplated hereby; and WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement to each of Harrah's and Merger Sub's willingness to enter into this Agreement, certain stockholders of Rio have entered into Stockholder Support Agreements with Harrah's dated as of the date of this Agreement in the form attached hereto as Exhibit A (the "Stockholder Support Agreements"), pursuant to which such stockholders have agreed, among other things, to vote all voting securities of Rio beneficially owned by them in favor of approval and adoption of the Agreement and the Merger; NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below, the parties agree as follows: ARTICLE I. THE MERGER Section 1.1. The Merger. Upon the terms and subject to the provisions of this Agreement and in accordance with Chapter 92A of the Nevada Revised Statutes (the "NRS"), at the Effective Time (as defined in Section 1.2), Merger Sub shall be merged with and into Rio. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and Rio shall continue as the surviving corporation (the "Surviving Corporation"). Section 1.2. Effective Time of the Merger. Subject to the provisions of this Agreement (including Section 7.1 hereof), articles of merger with respect to the Merger in such form as is required by NRS Section 92A.200 (the "Articles of Merger") shall be duly prepared, executed and acknowledged and thereafter delivered to the Secretary of State of the State of Nevada for filing, as provided in the NRS, as early as practicable on the Closing Date (as defined in Section 1.3). The Merger shall become effective at the later of the date of filing of the Articles of Merger or at such time within 90 days of the date of filing as is specified in the Articles of Merger (the "Effective Time"). Section 1.3. Closing. The closing of the Merger (the "Closing") will take place at such time and place to be agreed upon by the parties hereto, on a date to be specified by Harrah's and Rio, which shall be no later than the third business day after satisfaction or, if permissible, waiver of the conditions set forth in Article VI (the "Closing Date"), unless another date is agreed to by Harrah's and Rio. Section 1.4. Effect of the Merger. Upon becoming effective, the Merger shall have the effects set forth in the NRS. Without limiting the generality of the foregoing, and subject thereto, at the Effective A-1 Time, all properties, rights, privileges, powers and franchises of Merger Sub and Rio shall vest in the Surviving Corporation, and all debts, liabilities and duties of Merger Sub and Rio shall become the debts, liabilities and duties of the Surviving Corporation. Section 1.5. Articles of Incorporation and Bylaws of the Surviving Corporation. At the Effective Time, the Articles of Incorporation and Bylaws of the Surviving Corporation shall be amended to be identical to the Articles of Incorporation and Bylaws, respectively, of Merger Sub as in effect immediately prior to the Effective Time (except that the name of the Surviving Corporation shall be "Rio Hotel & Casino, Inc."), in each case until duly amended in accordance with applicable law. Section 1.6. Directors and Officers of the Surviving Corporation. The directors of Merger Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, each to hold office in accordance with the Articles of Incorporation and Bylaws of the Surviving Corporation, PROVIDED that, at Harrah's option, the board of directors may include the existing non-employee directors of Rio for a term not to exceed 90 days following the Effective Time. The officers of Merger Sub immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, each to hold office in accordance with the Articles of Incorporation and Bylaws of the Surviving Corporation. ARTICLE II. EFFECT OF THE MERGER ON SECURITIES OF THE CONSTITUENT CORPORATIONS Section 2.1. Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of any of the parties hereto or the holders of any of the following: (a) Rio Common Stock. Each share of common stock, par value $0.01 per share, of Rio ("Rio Common Stock") issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 2.1(b)) shall be converted, subject to Section 2.1(e) and 2.1(f), into the right to receive one (the "Exchange Ratio") validly issued, fully paid and non-assessable share of common stock, par value $0.10 per share, of Harrah's ("Harrah's Common Stock"). All shares of Rio Common Stock, when so converted, shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares shall cease to have any ownership or other rights with respect thereto, except the right to receive the Merger Consideration, as defined in Section 2.2(b), in exchange for such shares upon the surrender of such certificate in accordance with Section 2.2. (b) Cancellation of Treasury Stock and Harrah's-Owned Stock. All shares of Rio Common Stock that are owned by Rio as treasury stock and any shares of Rio Common Stock owned by Harrah's or any wholly-owned Subsidiary (as defined in Section 3.1) of Harrah's shall be canceled and retired and shall cease to exist and no consideration shall be delivered in exchange therefor. (c) Capital Stock of Merger Sub. Each issued and outstanding share of the common stock, par value $.01 per share, of Merger Sub shall be converted into and become one fully paid and nonassessable share of common stock, par value $.01 per share, of the Surviving Corporation. (d) Rio Debt Securities. All notes and other debt instruments of Rio that are outstanding at the Effective Time shall continue to be outstanding subsequent to the Effective Time as debt instruments of the Surviving Corporation, subject to their respective terms and provisions. (e) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted to reflect fully the effect of any stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Harrah's Common Stock or Rio Common Stock, as applicable), reorganization, recapitalization or any other like change with respect to Harrah's Common Stock or Rio Common Stock occurring after the date hereof and prior to the Effective Time. References to the Exchange Ratio elsewhere in this A-2 Agreement shall be deemed to refer to the Exchange Ratio as it may have been adjusted pursuant to this Section 2.1(e). (f) Fractional Shares. No certificates or scrip representing fractional shares of Harrah's Common Stock shall be issued in connection with the Merger, and such fractional share interests will not entitle the owner thereof to vote or to any rights as a stockholder of Harrah's. In lieu of any such fractional shares, each holder of Rio Common Stock upon surrender of a certificate (a "Certificate") for exchange shall be paid an amount in cash (without interest), rounded up to the nearest cent, determined by multiplying (i) the average closing price of Harrah's Common Stock as reported on the New York Stock Exchange ("NYSE") Composite Tape for the ten consecutive trading days immediately preceding the second business day prior to the Effective Time (the "Average Harrah's Common Stock Price") by (ii) the fractional interest to which such holder would otherwise be entitled (after taking into account all shares of Rio Common Stock then held of record by such holder). Section 2.2. Exchange of Certificates. (a) Exchange Agent. At or prior to the Effective Time, Harrah's shall deposit with a bank or trust company designated by Harrah's and reasonably acceptable to Rio (the "Exchange Agent"), for the benefit of the holders of shares of Rio Common Stock outstanding immediately prior to the Effective Time, for exchange in accordance with this Section 2.2, through the Exchange Agent, (i) certificates evidencing the shares of Harrah's Common Stock issuable pursuant to Section 2.1(a) in exchange for outstanding shares of Rio Common Stock and (ii) cash in an aggregate amount sufficient to pay for fractional shares pursuant to Section 2.1(f) (the shares and cash so deposited, together with any dividends or distributions with respect to such shares of Harrah's Common Stock payable after the Effective Time which also shall be deposited with the Exchange Agent, being hereinafter referred to collectively as the "Exchange Fund"). Any interest, dividends or other income earned on the investment of cash or other property held in the Exchange Fund shall be for the account of and payable to Harrah's. (b) Exchange Procedures. Promptly after the Effective Time, Harrah's will instruct the Exchange Agent to mail to each holder of record of Certificates (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Harrah's may reasonably specify), and (ii) instructions to effect the surrender of the Certificates in exchange for the certificates evidencing shares of Harrah's Common Stock (plus cash in lieu of fractional shares, if any, of Harrah's Common Stock as provided in Section 2.1(f)). Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, and such other customary documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor (A) certificates evidencing that number of whole shares of Harrah's Common Stock which such holder has the right to receive in accordance with the Exchange Ratio in respect of the shares of Rio Common Stock formerly evidenced by such Certificate, (B) any dividends or distributions to which such holder is entitled pursuant to Section 2.2(c), and (C) cash in respect of fractional shares as provided in Section 2.1(f) (such shares of Harrah's Common Stock, dividends, distributions, and cash, collectively, the "Merger Consideration"), and the Certificate so registered shall forthwith be canceled. In the event of a transfer of ownership of shares of Rio Common Stock which is not registered in the transfer records of Rio as of the Effective Time, the Merger Consideration may be issued and paid in accordance with this Article II to a transferee if the Certificate evidencing such shares of Rio Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer pursuant to this Section 2.2(b) and by evidence that any applicable stock transfer taxes have been paid. Until so surrendered, each outstanding Certificate that prior to the Effective Time represented shares of Rio Common Stock will be deemed from and after the Effective Time for all corporate purposes (other than the payment of dividends and subject to Section 2.1(f)) to evidence the ownership of the number of full shares of Harrah's Common Stock into which such shares of Rio Common Stock shall have been so converted. A-3 (c) Distributions With Respect to Unexchanged Shares of Harrah's Common Stock. No dividends or other distributions declared or made after the Effective Time with respect to shares of Harrah's Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to shares of Harrah's Common Stock they are entitled to receive until the holder of such Certificate shall surrender such Certificate. Subject to applicable law, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of Harrah's Common Stock issued in exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Harrah's Common Stock. (d) Transfers of Ownership. At the Effective time, the stock transfer books of Rio shall be closed, and there shall no further registration of transfers of Rio Common Stock thereafter on the records of Rio. If any certificate for shares of Harrah's Common Stock is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it will be a condition of the issuance thereof that the Certificate so surrendered will be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange will have paid to Harrah's or any agent designated by it any transfer or other taxes required by reason of the issuance of a certificate for Harrah's shares in any name other than that of the registered holder of the certificate surrendered, or have established to the reasonable satisfaction of Harrah's or any agent designated by it that such tax has been paid or is not payable. (e) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the former stockholders of Rio as of the date which is twelve months after the Effective Time shall be delivered to Harrah's, upon demand, and thereafter such former stockholders of Rio who have not theretofore complied with this Section 2.2 shall be entitled to look only to Harrah's for payment of the Merger Consideration to which they are entitled pursuant hereto. (f) No Liability. None of Harrah's, Merger Sub, Rio or the Exchange Agent shall be liable to any holder of Rio Common Stock for any Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. (g) Withholding Rights. Harrah's or the Exchange Agent shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of Certificates which prior to the Effective Time represented shares of Rio Common Stock such amounts as Harrah's or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local, or foreign tax law. To the extent that amounts are so withheld by Harrah's or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Rio Common Stock in respect of which such deduction and withholding was made by Harrah's or the Exchange Agent. (h) Lost, Stolen or Destroyed Certificates. In the event any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, such Merger Consideration as may be required pursuant to Section 2.2; PROVIDED, HOWEVER, that Harrah's may, in its discretion, and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Harrah's, the Surviving Corporation or the Exchange Agent with respect to the Certificates alleged to have been lost, stolen or destroyed. (i) Affiliates. Notwithstanding anything herein to the contrary, Certificates surrendered for exchange by any Affiliate (as defined in Section 5.12) of Rio shall not be exchanged until the later of (i) the date Harrah's has received an Affiliate Agreement (as defined in Section 5.12) from such Affiliate or (ii) the date such shares of Harrah's Common Stock are transferable pursuant to the Affiliate Agreement regardless of whether such agreement was executed by the Affiliate. A-4 Section 2.3. Rio Options. Effective at the Effective Time, subject, if necessary, to obtaining the consent of the holder thereof, each unexpired and unexercised outstanding option, whether or not then vested or exercisable in accordance with its terms, to purchase shares of Rio Common Stock (the "Rio Options") previously granted by Rio or its Subsidiaries under Rio's 1991 Non-Statutory Stock Option Plan, as amended, 1991 Directors' Stock Option Plan, as amended, and 1995 Long-Term Incentive Plan, as amended (collectively, the "Rio Stock Option Plans"), shall be converted automatically into an option to acquire the number of shares of Harrah's Common Stock (a "Substitute Option"), rounded down to the nearest whole share, determined by multiplying (i) the number of shares of Rio Common Stock subject to such Rio Option immediately prior to the Effective Time by (ii) the Exchange Ratio. The exercise price per share of Harrah's Common Stock subject to each Substitute Option shall be equal to the exercise price per share of Rio Common Stock subject to the relevant Rio Option divided by the Exchange Ratio and then rounded up to the nearest whole cent; PROVIDED, HOWEVER, that in the case of any Rio Option which is qualified as an incentive stock option under Section 422 of the Code, the conversion formula (both as to number of shares to be subject to the related Substitute Option and the exercise price of the related Substitute Option) shall be adjusted, if necessary, to comply with Section 424(a) of the Code. After the Effective Time, each Substitute Option shall be exercisable upon the same terms and conditions as were applicable to the related Rio Option immediately prior to the Effective Time (including those terms which may have caused such Rio Option/Substitute Option to become exercisable in full in connection with the consummation of the transactions contemplated by this Agreement). As soon as practicable after the Effective Time, Harrah's shall deliver to the holders of the Substitute Options appropriate notice setting forth such holders' rights pursuant thereto. Harrah's shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Harrah's Common Stock for delivery under the Rio Stock Option Plans, which shall be assumed in accordance with this Section 2.3. Within 30 days after the Effective Time, Harrah's shall file a registration statement on Form S-8 (or any successor or other appropriate forms) with respect to the shares of Harrah's Common Stock subject to such options and shall use its best efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such options remain outstanding. Rio (or, if appropriate, any committee administering the Rio Stock Option Plans) shall use its best efforts, prior to or as of the Effective Time, to take all necessary actions, pursuant to and in accordance with the terms of the Rio Stock Option Plans and the instruments evidencing the Rio Options, to provide for the conversion of the Rio Options into options to acquire Harrah's Common Stock in accordance with this Section 2.3. Furthermore, Rio shall use its best efforts to obtain the consent of the holders of the Rio Options if required in connection with such conversion. The Board of Directors of Rio shall, prior to or as of the Effective Time, take appropriate action to approve the deemed cancellation of the Rio Options for purposes of Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Harrah's shall, prior to or as of the Effective Time, take appropriate action to approve the deemed grant of options to purchase Harrah's Common Stock under the Rio Options (as converted pursuant to this Section 2.3) for purposes of Section 16(b) of the Exchange Act. ARTICLE III. REPRESENTATIONS AND WARRANTIES OF RIO Rio represents and warrants to Harrah's and Merger Sub that the statements contained in this Article III are true and correct except as set forth herein and in the disclosure schedule delivered by Rio to Harrah's and Merger Sub on or before the date of this Agreement (the "Rio Disclosure Schedule"). The Rio Disclosure Schedule shall be arranged in paragraphs corresponding to the numbered and lettered paragraphs contained in this Article III and the disclosure in any paragraph shall qualify other paragraphs in this Article III only to the extent that it is reasonable from a reading of such disclosure that it also qualifies or applies to such other paragraphs. A-5 Section 3.1. Organization of Rio and its Subsidiaries. Each of Rio and its Subsidiaries (as defined below) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization and has the requisite corporate, partnership or limited liability company power and authority to carry on its business as now being conducted. Each of Rio and its Subsidiaries is duly qualified or licensed to do business and is in good standing in each jurisdiction in which the property owned, leased or operated by it or the nature of the business conducted by it makes such qualification or licensing necessary, except where the failure to be so qualified, licensed or in good standing, would not be reasonably likely to have a material adverse effect on the business or properties (including, without limitation, Rio's development plans contemplated by the Phase VI Expansion Plan (as defined) and Rio's development plans of the Phase VI Land (as defined)), financial condition or results of operations of Rio and its Subsidiaries, taken as a whole (a "Rio Material Adverse Effect"); PROVIDED, HOWEVER, that the effect of economic changes that are applicable to the gaming industry generally, or the Las Vegas gaming industry in particular, shall be excluded from the definition of "Rio Material Adverse Effect" and from any determination as to whether a Rio Material Adverse Effect has occurred or may occur with respect to Rio. Rio has delivered to Harrah's a true and correct copy of the Articles of Incorporation and Bylaws of Rio, in each case as amended to the date of this Agreement. Assuming compliance by Harrah's with all Rio Gaming Laws (as defined in Section 3.15(b)) (including obtaining all necessary consents and approvals), the respective organizational documents of Rio's Subsidiaries do not contain any provision that would limit or otherwise restrict the ability of Harrah's, following the Effective Time, from owning or operating such Subsidiaries on the same basis as Rio.

The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby by Rio have been duly authorized by all necessary corporate action on the part of Rio, subject only to the approval and adoption of this Agreement and the Merger by a majority of Rio's stockholders. This Agreement has been duly executed and delivered by Rio and assuming the due authorization, execution and delivery by Harrah's and Merger Sub, constitutes the valid and binding obligation of Rio, enforceable against it in accordance with its terms.

To Rio's best knowledge, there are no facts, which if known to the regulators under the Rio Gaming Laws could reasonably be expected to result in the revocation, limitation or suspension of a license, finding of suitability, registration, permit or approval of it or them, or of any officer, director, other person performing management functions similar to an officer or partner, under any Rio Gaming Laws. Neither Rio nor any of its Subsidiaries has suffered a suspension or revocation of any material license, finding of suitability, registration, permit or approval held under the Rio Gaming Laws.

None of the information supplied by Rio or its Subsidiaries to be included or incorporated by reference from Rio SEC filings in the registration statement on Form S-4 pursuant to which shares of Harrah's Common Stock issued in the Merger will be registered under the Securities Act (the "Registration Statement"), of which the Joint Proxy Statement/ Prospectus will form a part, will, at the time the Registration Statement is declared effective by the SEC, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

Each employee benefit plan, within the meaning of Section 3(3) of ERISA, other than any multiemployer plan, within the meaning of Section 4001(a)(3) of ERISA, that is sponsored maintained or contributed to or with respect to which Harrah's has an obligation to contribute has been maintained in material compliance with the requirements of all applicable statutes, orders, rules and regulations which are applicable to such employee benefit plan, including but not limited to ERISA and the Code. With respect to each such employee benefit plan that is an employee pension benefit plan, within the meaning of Section 3(2) of ERISA, that is regulated under Title IV of ERISA: (i) Harrah's and any other entity that, together with Harrah's as of the relevant measuring date under ERISA, was or is required to be treated as single employer under Section 414 of the Code ("Harrah's ERISA Affiliate") have fulfilled their respective obligations under the minimum funding requirements of Section 302 of ERISA and Section 412 of the Code; (ii) no reportable event, as defined in Section 4043 of ERISA, has occurred and is continuing; (iii) no liability to the Pension Benefit Guaranty Corporation has been incurred, and (iv) no proceedings have been instituted by the Pension Benefit Guaranty Corporation to terminate any such plan.

Each of Harrah's and its Subsidiaries, and each of their respective directors (but with respect to non-employee directors, only to Harrah's best knowledge), officers, persons performing management functions similar to officers and, to Harrah's best knowledge, partners, are in compliance with the terms of the Harrah's Permits, except for such failures to comply, which singly or in the aggregate, would not, individually or in the aggregate, be reasonably likely to have a Harrah's Material Adverse Effect. Except as disclosed in the Harrah's SEC Reports filed prior to the date of this Agreement or as would not be reasonably likely to have a Harrah's Material Adverse Effect, the businesses of Harrah's and its Subsidiaries are not being conducted in violation of any law, ordinance or regulation of any Governmental Entity (including, without limitation, any Harrah's Gaming Laws), except for possible violations which individually or in the aggregate do not and would not be reasonably likely to have a Harrah's Material Adverse Effect. No investigation or review by any Governmental Entity with respect to Harrah's or any of its Subsidiaries is pending, or, to the best knowledge of Harrah's, threatened, nor has any Governmental Entity indicated any intention to conduct the same, other than those the outcome of which would not, individually or in the aggregate, be reasonably likely to have a Harrah's Material Adverse Effect. (b) The term "Harrah's Gaming Laws" means any Federal, state, local or foreign statute, ordinance, rule, regulation, permit, consent, registration, finding of suitability, approval, license, judgment, order, decree, injunction or other authorization, including any condition or limitation placed thereon, governing or relating to the current or contemplated casino and gaming activities and operations of Harrah's or any of its Subsidiaries, including, without limitation, the Nevada Gaming Control Act and the rules and regulations promulgated thereunder, the Clark County Code and the rules and regulations promulgated thereunder, the Douglas County Code and the rules and regulations promulgated thereunder, the Louisiana Economic Development and Gaming Corporation Law and the rules and regulations promulgated thereunder, the Louisiana Riverboat Economic Development and Gaming Control Act and the rules and regulations promulgated thereunder, the New Jersey Casino Control Act and the rules and regulations promulgated thereunder, the Illinois Riverboat Gambling Act and the rules and regulations promulgated thereunder, the Mississippi Gaming Control Act and the rules and regulations promulgated thereunder, the Missouri Riverboat Gambling Act and the rules and regulations promulgated thereunder, the Indiana Riverboat Gambling Act and the rules and regulations of the Indiana Gaming Commission and the codes, rules and regulations promulgated thereunder, the Casino Control Act 1992 (New South Wales) and the rules and regulations promulgated thereunder, the Indian Gaming Regulatory Act of 1988 and the rules and regulations promulgated thereunder, any state-tribal gaming compact and any applicable state gaming law and any federal or state laws relating to currency transactions.

To Harrah's best knowledge, there are no facts, which if known to the regulators under the Harrah's Gaming Laws could reasonably be expected to result in the revocation, limitation or suspension of a license, finding of suitability, registration, permit or approval of it or them, or of any officer, director, person performing management functions similar to an officer or partner, under any Harrah's Gaming Laws. Neither Harrah's nor any of its Subsidiaries has suffered a suspension or revocation of any material license , finding of suitability, registration, permit or approval held under the Harrah's Gaming Laws.

Section 4.20. Agreements, Contracts and Commitments. (a) Except as disclosed in the Harrah's SEC Reports filed prior to the date of this Agreement or as disclosed in Schedule 4.20(a) of the Harrah's Disclosure Schedule, as of the date of this Agreement, A-28 neither Harrah's nor any of its Subsidiaries is a party to any oral or written contract, agreement or commitment to be performed after the date hereof which would be a material contract (as defined in Item 601(b)(10) of Regulation S-K of the SEC, collectively, the "Harrah's Material Contracts").

Section 4.21. Information Regarding HJC. Except as disclosed on Schedule 4.21 of the Harrah's Disclosure Schedule or as would not be reasonably likely to have a Harrah's Adverse Effect, the Harrah's Form 10-K filed as of March 10, 1998 and the Harrah's Form 10-Q filed as of August 7, 1998 did not at the time they were filed (or if amended or superseded by a filing prior to the date of this Agreement, then on the date of such filing), and do not as of the date hereof, contain any untrue statement of a material fact relating to HJC or omit to state a material fact relating to HJC required to be stated in such Form 10-K and Form 10-Q or necessary in order to make the statements relating to HJC therein, in the light of the circumstances under which they were made, not misleading.

Rio agrees not to release any Third Party from, or waive any provision of, any standstill agreement to which it is a party or any confidentiality agreement between it and another person who has made, or who may reasonably be considered likely to make, an Acquisition Proposal, unless the Board of Directors of Rio determines in good faith, based on the advice of A-33 outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary duties to Rio's stockholders under applicable law. (b) Rio shall notify Harrah's promptly after receipt by Rio or Rio's knowledge of the receipt by any of its advisors of any Acquisition Proposal or any request for non-public information in connection with an Acquisition Proposal or for access to the properties, books or records of Rio by any person or entity that informs such party that it is considering making or has made an Acquisition Proposal. Such notice shall be made orally and in writing and shall indicate the identity of the offeror and the terms and conditions of such proposal, inquiry or contact. Rio shall (i) keep Harrah's informed of the status (including any change to the material terms) of any such Acquisition Proposal or request for non-public information and (ii) provide to Harrah's as soon as practicable after receipt or delivery thereof with copies of all correspondence and other written material (A) sent or provided to Rio or any of its employees, representatives or agents from any Third Party in connection with any Acquisition Proposal or request for non-public information or (B) sent or provided by Rio or any of its employees, representatives or agents to any Third Party in connection with any Acquisition Proposal or request for non-public information. (c) Except as expressly permitted by this Section 5.4, neither the Board of Directors of Rio nor any committee thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a manner adverse to Harrah's, the approval or recommendation by the Board of Directors of Rio or any such committee of this Agreement or the Merger, (ii) approve or cause Rio to enter into letter of intent, agreement in principle or any legally binding acquisition agreement or similar agreement relating to any Acquisition Proposal (any such legally binding agreement, an "Acquisition Agreement") or (iii) approve or recommend, or propose to publicly approve or recommend, any Acquisition Proposal. Notwithstanding the foregoing, if Rio has received a Superior Proposal, the Board of Directors of Rio may, prior to approval of the Merger by Rio's stockholders and subject to this and the following sentences, terminate this Agreement pursuant to Section 7.1(f), but only at a time that is more than 48 hours following receipt by Harrah's of written notice advising Harrah's that the Board of Directors of Rio is prepared to accept such Superior Proposal, specifying the material terms and conditions of such Superior Proposal and identifying the Third Party making such Superior Proposal; PROVIDED, HOWEVER, that concurrently with or immediately after such termination, the Board of Directors of Rio shall cause Rio to enter into an Acquisition Agreement with respect to such Superior Proposal. (d) Nothing contained in this Section 5.4 shall prohibit Rio from taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making any disclosure to Rio's stockholders if, in the good faith judgment of the Board of Directors of Rio, based on the advice of outside legal counsel, failure to so disclose would be inconsistent with its fiduciary obligations under applicable law; PROVIDED, HOWEVER, that neither Rio nor the Board of Directors of Rio (nor any committee thereof) shall withdraw or modify, or propose publicly to withdraw or modify, its position with respect to this Agreement or the Merger, or approve or recommend, or propose publicly to approve or recommend, an Acquisition Proposal.

A-36 (b) Rio and Harrah's shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement which causes such party to believe that there is a reasonable likelihood that any approval needed from a Governmental Entity will not be obtained or that the receipt of any such approval will be materially delayed. Rio and Harrah's shall take any and all actions reasonably necessary to vigorously defend, lift, mitigate and rescind the effect of any litigation or administrative proceeding adversely affecting this Agreement or the transactions contemplated hereby or thereby, including, without limitation, promptly appealing any adverse court or administrative order or injunction to the extent reasonably necessary for the foregoing purposes.

(b) For a period of six years after the Effective Time, Harrah's shall maintain or shall cause the Surviving Corporation to maintain in effect a directors' and officers' liability insurance policy covering those persons who are currently covered by Rio's directors' and officers' liability insurance policy (copies of which have been heretofore delivered by Rio to Harrah's) with coverage in amount and scope at least as favorable as Rio's existing coverage; provided that in no event shall Harrah's or the Surviving Corporation be required to expend in the aggregate in excess of 200% of the annual premium currently paid by Rio for such coverage; and if such premium would at any time exceed 200% of the such amount, then Harrah's or the Surviving Corporation shall maintain insurance policies which provide the maximum and best coverage available at an annual premium equal to 200% of such amount. (c) The provisions of this Section 5.10 are intended to be an addition to the rights otherwise available to the current officers and directors of Rio by law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives.

(b) For purposes of determining eligibility to participate, vesting and entitlement to benefits where length of service is relevant under any employee benefit plan or arrangement of Harrah's or the Surviving Corporation, other than for purposes of benefit accrual under any Pension Plan, employees of Rio and its Subsidiaries as of the Effective Time shall receive service credit for service with Rio and any of its Subsidiaries to the same extent such service was granted under the Employee Plans; provided, however, that such service need not be credited to the extent that it would result in a duplication of benefits. (c) Nothing in this Agreement is intended to create any right of employment for any person or to create any obligation for Harrah's or the Surviving Corporation to continue any Employee Plan of Rio following the Effective Time, except as provided in Sections 2.3 and 5.11(a). (d) Harrah's will, or will cause the Surviving Corporation and its Subsidiaries to, (i) waive all limitations as to preexisting conditions exclusions and waiting periods with respect to participation and coverage requirements applicable to the Affected Employees under any Welfare Plans that such employees may be eligible to participate in after the Closing Date, other than limitations or waiting periods that are already in effect with respect to such employees and that have not been satisfied as of the Closing Date under any Welfare Plan maintained for the Affected Employees immediately prior to the Closing Date, and (ii) use its best efforts to provide each Affected Employee with credit for any co-payments and deductibles paid prior to the Closing Date in satisfying any applicable deductible or out-of-pocket requirements under any welfare plans that such employees are eligible to participate in after the Closing Date.

Neither Rio nor Harrah's, nor any of their respective Subsidiaries or other Affiliates, shall take any action, or fail to take any action, that is not specifically provided for by this Agreement that would or would be reasonably likely to adversely affect the treatment of the Merger as a reorganization under Section 368(a) of the Code.

Section 5.15. Further Assurances and Actions. (a) Subject to the terms and conditions herein, each of the parties hereto agrees to use its reasonable best efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement, including, without limitation, (i) using their respective reasonable best efforts to obtain all licenses, permits, consents, approvals, authorizations, qualifications and orders of Governmental Entities and parties to contracts with each party hereto as are necessary for consummation of the transactions contemplated by this Agreement, and (ii) to fulfill all conditions precedent applicable to such party pursuant to this Agreement.

Harrah's payment of a termination fee pursuant to this subsection shall be the sole and exclusive remedy of Rio against Harrah's and any of its Subsidiaries and their respective directors, officers, employees, agents, advisors or other representatives with respect to the occurrences giving rise to such payment; PROVIDED that this limitation shall not apply in the event of a willful breach of this Agreement by Harrah's.

If it is ever held that any covenant hereunder is too broad to permit enforcement of such covenant to its fullest extent, each party agrees that a court of competent jurisdiction may enforce such covenant to the maximum extent permitted by law, and each party hereby consents and agrees that such scope may be judicially modified accordingly in any proceeding brought to enforce such covenant. Section 8.9. Specific Performance. The parties hereto agree that the remedy at law for any breach of this Agreement will be inadequate and that any party by whom this Agreement is enforceable shall be entitled to specific performance in addition to any other appropriate relief or remedy.

STOCKHOLDER -------------------------------------- Agreed and Acknowledged: HARRAH'S ENTERTAINMENT, INC. - ------------------------------------------- By: Its: A-A-3 EXHIBIT B FORM OF AFFILIATE LETTER Harrah's Entertainment, Inc. Ladies and Gentlemen: I have been advised that as of the date of this letter I may be deemed to be an "affiliate" of Rio Hotel & Casino, Inc., a Nevada corporation ("Rio"), as the term "affiliate" is defined for purposes of paragraphs (c) and (d) of Rule 145 of the rules and regulations (the "Rules and Regulations") of the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended, (the "Act"). Pursuant to the terms of the Merger Agreement, dated as of August 9, 1998 (the "Agreement"), between Harrah's Entertainment, Inc., a Delaware corporation ("Harrah's"), Harrah's Sub Corp., a Nevada corporation ("Merger Sub"), and Rio, Merger Sub will be merged with and into Rio (as defined in the Agreement) (the "Merger"). As a result of the Merger, I may receive shares of Common Stock, par value $0.10 per share, of Harrah's (as defined in the Agreement) (the "Harrah's Common Stock") in exchange for shares owned by me of Common Stock, par value $0.01 per share, of Rio. 1. Compliance with the Act. I represent, warrant and covenant to the Harrah's that in the event I receive any Harrah's Common Stock as a result of the Merger: A. I shall not make any sale, transfer or other disposition of the Harrah's Common Stock in violation of the Act or the Rules and Regulations. B. I have carefully read this letter and the Agreement and discussed the requirements of such documents and other applicable limitations upon my ability to sell, transfer or otherwise dispose of the Harrah's Common Stock to the extent I felt necessary, with my counsel or counsel for Rio. C. I have been advised that the issuance of Harrah's Common Stock to me pursuant to the Merger will be registered with the Commission under the Act on a Registration Statement on Form S-4. However, I have also been advised that, since at the time the Merger is submitted for a vote of the stockholders of Rio, I may be deemed to have been an affiliate of Rio and the distribution by me of the Harrah's Common Stock has not been registered under the Act, I may not sell, transfer or otherwise dispose of the Harrah's Common Stock issued to me in the Merger unless (i) such sale, transfer or other disposition has been registered under the Act, (ii) such sale, transfer or disposition is made in conformity with Rule 145 promulgated by the Commission under the Act, or (iii) in the opinion of counsel reasonably acceptable to Harrah's, or pursuant to a "no action" letter obtained by the undersigned from the staff of the Commission, such sale, transfer or other disposition is otherwise exempt from registration under the Act. D. I understand that Harrah's is under no obligation to register the sale, transfer or disposition of the Harrah's Common Stock by me or on my behalf under the Act or to take any other action necessary in order to make compliance with an exemption from such registration available; PROVIDED, HOWEVER, that Harrah's shall meet the requirements of paragraph (c) of Rule 144 promulgated under the Act. E. I also understand that stop transfer instructions will be given to the Harrah's transfer agent with respect to the Harrah's Common Stock and that there will be placed on the Certificates for the Harrah's Common Stock issued to me, or any substitutions therefor, a legend stating in substance: "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF A-B-1 1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED AUGUST 9, 1998 BETWEEN THE REGISTERED HOLDER HEREOF AND HARRAH'S ENTERTAINMENT, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF HARRAH'S ENTERTAINMENT, INC." F. I also understand that unless the transfer by me of my Harrah's Common Stock has been registered under the Act or is a sale made in conformity with the provisions of Rule 145, Harrah's reserves the right to put the following legend on the certificates issued to my transferee: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933." It is understood and agreed that the legends set forth in paragraphs E and F above shall be removed by delivery of substitute certificates without such legend if such legend is not required for purposes of the Act or this Agreement. It is understood and agreed that such legends and the stop orders referred to above will be removed if (i) one year shall have elapsed from the date the undersigned acquired the Harrah's Common Stock received in the Merger and the provisions of Rule 145(d)(2) are then available to the undersigned, (ii) two years shall have elapsed from the date the undersigned acquired Harrah's Common Stock received in the Merger and the provisions of Rule 145(d)(3) are then available to the undersigned, or (iii) Harrah's has received either an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to Harrah's, or a "no action" letter obtained by the undersigned from the staff of the Commission, to the effect that the restrictions imposed by Rule 145 under the Act no longer apply to the undersigned. 2. Intentionally Omitted. 3. Certain Tax Matters. The undersigned does not intend to take a position on any federal or state income tax return that is inconsistent with the treatment of the Merger as a tax-free reorganization for federal or state income tax purposes. A-B-2 Execution of this letter should not be considered an admission on my part that I am an "affiliate" of Rio as described in the first paragraph of this letter or as a waiver of any rights I may have to object to any claim that I am such an affiliate on or after the date of this letter.

The aggregate fair market value of the shares of Parent voting stock received by each stockholder of Target will be approximately equal to the fair market value of the shares of Target stock surrendered in the Merger, as determined by arm's-length negotiations between the respective managements and representatives of Parent and Target. 4. No assets of Target have been sold, transferred or otherwise disposed of which would prevent Target from continuing its historic business or from using a significant portion of its historic business assets in a business following the Merger. 5.

Target is not an investment company as defined in Section 368(a)(2)(F)(iii) and (iv) of the Code. 14.

A-E-3 ANNEX B [LOGO] August 9, 1998 Board of Directors Harrah's Entertainment, Inc. 1023 Cherry Road Memphis, TN 38117 Lady and Gentlemen: BT Wolfensohn has acted as financial advisor to Harrah's Entertainment, Inc.

As set forth more fully in the Merger Agreement, as a result of the Transaction, each share of the Common Stock, par value $0.01 per share, of the Company ("Company Common Stock") not owned directly or indirectly by the Company or Harrah's will be converted into the right to receive one share (the "Exchange Ratio") of Common Stock, par value $0.10 per share, of Harrah's ("Harrah's Common Stock"). The terms and conditions of the Transaction are more fully set forth in the Merger Agreement. You have requested BT Wolfensohn's opinion, as investment bankers, as to the fairness, from a financial point to view, to Harrah's of the Exchange Ratio. In connection with BT Wolfensohn's role as financial advisor to Harrah's, and in arriving at its opinion, BT Wolfensohn has reviewed certain publicly available financial and other information concerning the Company and Harrah's and certain internal analyses and other information furnished to it by the Company and Harrah's. BT Wolfensohn has also held discussions with members of the senior managements of the Company and Harrah's regarding the businesses and prospects of their respective companies and the joint prospects of a combined company. In addition, BT Wolfensohn has (i) reviewed the reported prices and trading activity for Company Common Stock and Harrah's Common Stock, (ii) compared certain financial and stock market information for the Company and Harrah's with similar information for certain other companies whose securities are publicly traded, (iii) reviewed the financial terms of certain recent business combinations which it deemed comparable in whole or in part, (iv) reviewed the terms of the Merger Agreement, and (v) performed such other studies and analyses and considered such other factors as it deemed appropriate. BT Wolfensohn has not assumed responsibility for independent verification of, and has not independently verified, any information, whether publicly available or furnished to it, concerning the Company or Harrah's, including, without limitation, any financial information, forecasts or projections considered in connection with the rendering of its opinion. Accordingly, for purposes of its opinion, BT Wolfensohn has assumed and relied upon the accuracy and completeness of all such information and BT Wolfensohn has not conducted a physical inspection of any of the properties or assets, and has not prepared or obtained any independent evaluation or appraisal of any of the assets or liabilities, of the Company or Harrah's. With respect to the financial forecasts and projections, including the analyses and forecasts of certain cost savings, operating efficiencies, revenue effects and financial synergies expected by Harrah's and the Company to be achieved as a result of the Transaction (collectively, the "Synergies"), made available to BT Wolfensohn and used in its analyses, BT Wolfensohn has assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of Harrah's Entertainment, Inc. August 9, 1998 Page 2 the Company or Harrah's, as the case may be, as to the matters covered thereby. In rendering its opinion, BT Wolfensohn expresses no view as to the reasonableness of such forecasts and projections, including the Synergies, or the assumptions on which they are based. BT Wolfensohn's opinion is necessarily based upon economic, market and other conditions as in effect on, and the information made available to it as of, the date hereof. For purposes of rendering its opinion, BT Wolfensohn has assumed that, in all respects material to its analysis, the representations and warranties of Harrah's, Harrah's Sub and the Company contained in the Merger Agreement are true and correct, Harrah's, Harrah's Sub and the Company will each perform all of the covenants and agreements to be performed by it under the Merger Agreement and all conditions to the obligations of each of Harrah's, Harrah's Sub and the Company to consummate the Transaction will be satisfied without any waiver thereof. BT Wolfensohn has also assumed that all material governmental, regulatory or other approvals and consents required in connection with the consummation of the Transaction will be obtained and that in connection with obtaining any necessary governmental, regulatory or other approvals and consents, or any amendments, modifications or waivers to any agreements, instruments or orders to which either Harrah's or the Company is a party or is subject or by which it is bound, no limitations, restrictions or conditions will be imposed or amendments, modifications or waivers made that would have a material adverse effect on Harrah's or the Company or materially reduce the contemplated benefits of the Transaction to Harrah's. In addition, you have informed BT Wolfensohn, and accordingly for purposes of rendering its opinion BT Wolfensohn has assumed, that the Transaction will be tax-free to each of Harrah's and the Company and their respective stockholders. This opinion is addressed to, and for the use and benefit of, the Board of Directors of Harrah's and is not a recommendation to the stockholders of Harrah's to approve the Transaction. This opinion is limited to the fairness, from a financial point of view, to Harrah's of the Exchange Ratio, and BT Wolfensohn expresses no opinion as to the merits of the underlying decision by Harrah's to engage in the Transaction. BT Wolfensohn is engaged in the merger and acquisition and client advisory business of Bankers Trust (together with its affiliates the "BT Group") and, for legal and regulatory purposes, is a division of BT Alex.

One or more members of the BT Group have, from time to time, provided investment banking, commercial banking (including extension of credit) and other financial services to Harrah's or its affiliates for which it has received compensation. A member of the BT Group acted as agent on a $2.1 billion revolving credit facility to Harrah's and was also the lender and the administrative agent for Harrah's Jazz Company's $175 million credit facility. In the ordinary course of business, members of the BT Group may actively trade in the securities and other instruments and obligations of Harrah's and the Company for their own accounts and for the accounts of their customers. Accordingly, the BT Group may at any time hold a long or short position in such securities, instruments and obligations. Based upon and subject to the foregoing, it is BT Wolfensohn's opinion as investment bankers that the Exchange Ratio is fair, from a financial point of view, to Harrah's. Very truly yours, BT WOLFENSOHN ANNEX C [LOGO] As of August 9, 1998 Board of Directors Rio Hotel & Casino, Inc. 3700 West Flamingo Las Vegas, Nevada 89103 Members of the Board of Directors: Rio Hotel & Casino, Inc. (the "Company"), Harrah's Entertainment, Inc. (the "Acquiror") and Harrah's Acquisition Corp. III, a newly formed wholly owned subsidiary of the Acquiror (the "Acquisition Sub") have entered into an Agreement and Plan of Merger dated as of August 9, 1998 (the "Agreement") pursuant to which Acquisition Sub will be merged with and into the Company in a transaction (the "Merger") in which each outstanding share of the Company's common stock, par value $.01 per share (the "Company Shares"), will be converted into the right to receive one (1) share (the "Exchange Ratio") of the common stock of the Acquiror, par value $.10 per share ("the Acquiror Shares"). You have asked us whether, in our opinion, the Exchange Ratio is fair from a financial point of view to the holders of the Company Shares, other than the Acquiror and its affiliates. In arriving at the opinion set forth below, we have, among other things: (1) Reviewed certain publicly available business and financial information relating to the Company and the Acquiror that we deemed to be relevant; (2) Reviewed certain information, including financial forecasts, relating to the business, earnings, cash flow, assets, liabilities and prospects of the Company and the Acquiror, as well as the amount and timing of the cost savings and related expenses and synergies expected to result from the Merger (the "Expected Synergies") furnished to us by the Company and the Acquiror, respectively; (3) Conducted discussions with members of senior management and representatives of the Company and the Acquiror concerning the matters described in clauses 1 and 2 above, as well as their respective businesses and prospects before and after giving effect to the Merger and the Expected Synergies; (4) Reviewed the market prices and valuation multiples for the Company Shares and the Acquiror Shares and compared them with those of certain publicly traded companies that we deemed to be relevant; (5) Reviewed the results of operations of the Company and the Acquiror and compared them with those of certain publicly traded companies that we deemed to be relevant; (6) Compared the proposed financial terms of the Merger with the financial terms of certain other transactions that we deemed to be relevant; (7) Participated in certain discussions and negotiations among representatives of the Company and the Acquiror and their financial and legal advisors; (8) Reviewed the potential pro forma impact of the Merger; (9) Reviewed the Agreement and the forms of agreements attached as Exhibits thereto; and (10) Reviewed such other financial studies and analyses and took into account such other matters as we deemed necessary, including our assessment of general economic, market and monetary conditions. In preparing our opinion, we have assumed and relied on the accuracy and completeness of all information supplied or otherwise made available to us, discussed with or reviewed by or for us, or publicly available, and we have not assumed any responsibility for independently verifying such information or undertaken an independent evaluation or appraisal of any of the assets or liabilities of the Company or the Acquiror or been furnished with any such evaluation or appraisal. In addition, although representatives of Merrill Lynch visited certain properties of both the Company and the Acquiror, we have not assumed any obligation to conduct, nor have we conducted, any physical inspection of the properties or facilities of the Company or the Acquiror. With respect to the financial forecast information and the Expected Synergies furnished to or discussed with us by the Company or the Acquiror, we have assumed that they have been reasonably prepared and reflect the best currently available estimates and judgment of the Company's or the Acquiror's management as to the expected future financial performance of the Company or the Acquiror, as the case may be, and the Expected Synergies. We have further assumed that the Merger will be accounted for as a purchase under U. S. generally accepted accounting principles and that it will qualify as a tax-free reorganization for U.S. federal income tax purposes. Our opinion is necessarily based upon market, economic and other conditions as they exist and can be evaluated on, and on the information made available to us as of, the date hereof. We have assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the Merger, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that will have a material adverse effect on the contemplated benefits of the Merger. Although at various times during the course of our engagement we have contacted other parties regarding potential transactions involving the Company, we have not been specifically authorized by the Company to solicit third-party indications of interest in the Company in connection with our evaluation of the Exchange Ratio. We are acting as financial advisor to the Company in connection with the Merger and will receive a fee from the Company for our services, a significant portion of which is contingent upon the consummation of the Merger. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. In addition, in the ordinary course of our business, we may actively trade the Company Shares and other securities of the Company as well as the Acquiror Shares and other securities of the Acquiror, for our own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities. This opinion is for the use and benefit of the Board of Directors of the Company. Our opinion does not address the merits of the underlying decision by the Company to engage in the Merger and does not constitute a recommendation to any shareholder as to how such shareholder should vote on the proposed Merger. We are not expressing any opinion herein as to the prices at which the Acquiror Shares will trade following the announcement or consummation of the Merger. On the basis of and subject to the foregoing, we are of the opinion that, as of the date hereof, the Exchange Ratio is fair from a financial point of view to the holders of the Company Shares, other than the Acquiror and its affiliates.
