                  MERGER PROPOSED--YOUR VOTE IS VERY IMPORTANT

    The Board of Directors of Sodak Gaming, Inc. has approved the merger of
Sodak with a subsidiary of International Game Technology. Under the merger
agreement, each outstanding share of Sodak common stock will be converted into
the right to receive $10.00 in cash, without interest.

    We cannot complete the merger unless we obtain the approval of Sodak
stockholders owning at least a majority of Sodak's outstanding common stock and
unless we obtain the necessary regulatory approvals described in this document.
We are inviting you, as a holder of Sodak common stock, to attend a special
meeting to vote on the merger proposal.

    The special meeting of Sodak's stockholders will be held at 11:00 a.m.,
local time, on Wednesday, July 7, 1999, at the Rushmore Plaza Holiday Inn, 505
North 5(th) Street, Rapid City, South Dakota.

    We encourage you to read this entire document carefully. This document
provides detailed information about the merger we are proposing, and includes
the merger agreement as Appendix A. You can also obtain information about Sodak
from publicly available documents filed with the Securities and Exchange
Commission.

    Your Board of Directors has determined that the merger is in the best
interests of Sodak and its stockholders, and has unanimously approved the merger
agreement and the merger. In making its determination, the Board took into
account, among other things, the opinion, dated March 10, 1999, of Sodak's
financial advisor, Salomon Smith Barney, that the $10.00 per share cash
consideration to be received by the stockholders in the merger was fair to the
stockholders from a financial point of view. THE BOARD UNANIMOUSLY RECOMMENDS
THAT YOU VOTE "FOR" APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE
MERGER.

    Your vote is very important. Whether or not you plan to attend the special
meeting, please take the time to vote by completing and mailing the enclosed
proxy card to us. A prepaid return envelope is provided for this purpose. If you
date and mail your proxy card without indicating how you want to vote, your
proxy will be counted as a vote "for" adoption of the merger agreement and the
merger. If you do not return your card or instruct your broker how to vote any
shares held for you in your broker's name, the effect will be a vote against the
merger. You may revoke your proxy at any time before it is exercised and it will
not be used if you attend the meeting and prefer to vote in person. Your Board
and I urge all stockholders to be present in person or by proxy.

    If the merger is consummated, you will receive instructions for surrendering
your common stock certificates in exchange for $10.00 cash for each share and a
letter of transmittal to be used for this purpose. You should not submit your
stock certificates for exchange until you have received the instructions and the
letter of transmittal.

    PLEASE COMPLETE, SIGN, DATE AND PROMPTLY RETURN YOUR PROXY CARD IN THE
ENCLOSED ENVELOPE.

                                          Sincerely yours,

                                          /s/ Roland W. Gentner

       Dakota corporation and a wholly-owned subsidiary of IGT, and Sodak
       Gaming, Inc., a South Dakota corporation, and the merger contemplated by
       that agreement, as a result of which each outstanding share of common
       stock, par value $0.001 per share, of Sodak (other than shares owned by
       Sodak, IGT or their respective subsidiaries, which will be canceled, and
       shares owned by Sodak stockholders who properly demand and perfect their
       statutory dissenters' appraisal rights) will be converted, upon the
       effectiveness of the merger, into the right to receive $10.00 in cash,
       without interest.

    2.  To transact any other business as may properly come before the special
       meeting or any adjournments or postponements of the special meeting.

    The Board of Directors has fixed the close of business on May 26, 1999 as

meeting. Accordingly, only holders of record of Sodak common stock on that date
are entitled to notice of and to vote at the special meeting or any adjournments
or postponements of the special meeting.

THE COMPANIES (page 8)

SODAK GAMING, INC.
5301 S. HIGHWAY 16
RAPID CITY, SOUTH DAKOTA 57701
(605) 341-5400

    Sodak, a South Dakota corporation, is a leading distributor and financier of
gaming equipment and a broad range of gaming-related products and services, and
is a provider of wide area progressive systems, primarily to Native American
casinos.

    At March 31, 1999, the end of our first quarter, our total assets were
$144.4 million and our total shareholders' equity was $110.3 million. Our total
revenue for fiscal 1998 was $132.5 million.

INTERNATIONAL GAME TECHNOLOGY
9295 PROTOTYPE DRIVE
RENO, NEVADA 89511
(702) 448-7777

    International Game Technology, which, together with its subsidiaries, we
refer to as IGT, is a world leader in the design, development and manufacture of
microprocessor-based gaming products and software systems in all jurisdictions
where gaming is legal.

    At April 3, 1999, the end of its second quarter, IGT's total assets were
$1.5 billion and its total stockholder's equity was $469.2 million. Its total
revenue for fiscal 1998, which ended September 30, 1998, was $824.1 million.

THE MERGER (page 23)

    We propose a merger in which Sodak will become a wholly-owned subsidiary of
IGT. On completion of the merger, each of your shares of Sodak common stock will
automatically become the right to receive $10.00 in cash, without interest, from
IGT. We have attached the merger agreement to this document as Appendix A.
Please read the merger agreement. It is the legal document that governs the
merger.

OUR RECOMMENDATION TO STOCKHOLDERS (page 10)

    The Board of Directors of Sodak believes that the merger is fair to you and
in your best interests, and unanimously recommends that you vote "FOR" approval
and adoption of the merger agreement and the merger.

OPINION OF FINANCIAL ADVISOR (page 11)

    On March 10, 1999, Salomon Smith Barney, our financial advisor, delivered an
opinion to the Sodak Board of Directors that, as of the date of the opinion, the
cash merger consideration of $10.00 per share was fair from a financial point of
view to the holders of Sodak common stock. We have attached the opinion as
Appendix B. This opinion does not constitute a recommendation as to how any
stockholder should vote on the merger agreement and merger. You should read it
completely to understand the procedures followed, assumptions made, matters
considered and limitations of the review undertaken by Salomon Smith Barney in
providing this opinion.

THE SPECIAL MEETING (page 6)

    The special meeting of Sodak stockholders will be held at 11:00 a.m., local
time, on Wednesday, July 7, 1999, at the Rushmore Plaza Holiday Inn, 505 North
5(th) Street, Rapid City, South Dakota. At the special meeting, you will be
asked to approve and adopt the merger agreement and the merger, and to act on
any other matters that are properly brought before the special meeting.

RECORD DATE; VOTE REQUIRED (page 7)

    You may vote at the special meeting if you owned Sodak common stock at the
close of business on May 26, 1999. The approval and adoption of the merger
agreement and the

                                       3
<PAGE>
merger requires the affirmative vote of the holders of at least a majority of
the outstanding shares of Sodak common stock entitled to vote at the special
meeting. Accordingly, a failure to vote or an abstention has the same effect as
voting against the merger.

    You may vote your shares in person by attending the special meeting or by
mailing us your proxy if you are unable or do not wish to attend.

IRREVOCABLE PROXY AND VOTING AGREEMENTS (page 32 and Appendix C)

    Each of our four major stockholders, Harrah's Operating Company, Tom Celani,
Mike Wordeman and Roland Gentner, has entered into an irrevocable proxy and
voting agreement with IGT. Under the voting agreements, each of those four
stockholders agreed to vote all of the Sodak common stock owned by that
stockholder in favor of the merger. These voting agreements terminate if the
merger agreement is terminated. Those four stockholders collectively own
approximately 52% of our common stock. Accordingly, unless these agreements are
terminated, the approval of the merger by Sodak's stockholders is virtually
assured.

CONDITIONS TO COMPLETION OF THE MERGER (page 30)

    Completion of the merger depends on a number of conditions being met,
including:

    - approval of Sodak stockholders holding at least a majority of the
      outstanding Sodak common stock

    - receipt of necessary regulatory approvals and expiration of antitrust
      waiting periods

    - IGT obtaining necessary financing

    - our divestiture of the MISS MARQUETTE riverboat

    - our divestiture of our 50% joint venture interest in developing a gaming
      riverboat in Louisiana

    - Roland Gentner, chief executive officer of Sodak, and certain other
      employees of Sodak remaining employed with Sodak

    - dissenting shares comprising less than 10% of the outstanding Sodak common
      stock

    - no litigation having been brought or threatened by any government agency
      to block the merger and no judicial order being in force prohibiting the
      merger.

    On March 31, 1999, we entered into an agreement with HWCC-Louisiana, Inc., a
subsidiary of Hollywood Casino Corporation, for the sale of our interest in the
Louisiana joint venture. The agreement was subject to the approval of the
Louisiana Gaming Control Board which was granted on April 20, 1999. The transfer
of our interest to HWCC-Louisiana, which was finalized on April 23, 1999,
satisfied that condition to the merger.

    On May 19, 1999, IGT announced that it had completed the private placement
of $1.0 billion in aggregate principal amount of its senior notes. A portion of
the proceeds of that offering are expected to be used to finance IGT's
acquisition of Sodak. The financing raised by the private placement satisfied
the financing condition to the merger.

    Either IGT or Sodak could choose to complete the merger even though a
closing condition has not been satisfied, as long as the law allows it to do so.
We cannot be certain when, or if, the conditions to the merger will be satisfied
or waived, or that the merger will be completed.

REGULATORY MATTERS (page 19)

    The merger cannot take place until the necessary regulatory approvals have
been received and any waiting periods required by law have expired. Sodak and
IGT have filed (or will promptly file) all of the required applications or
notices necessary to complete the merger with each of the regulatory
authorities. We cannot be sure whether or when we will receive the regulatory
approvals or that we will obtain the approvals without conditions that would be
detrimental to Sodak or IGT.

    We cannot complete the merger unless gaming regulatory requirements are
complied with, and approvals obtained, in a number of

                                       4
<PAGE>
jurisdictions in which Sodak and IGT operate gaming activities.

    We filed premerger notification and report forms with the Federal Trade
Commission and the Department of Justice under the Hart-Scott-Rodino Antitrust
Improvements Act on May 17, 1999. The Federal Trade Commission granted early
termination of the waiting period on June 1, 1999, with immediate effectiveness.

TERMINATION OF THE MERGER AGREEMENT; TERMINATION FEES AND EXPENSES (page 31)

    Sodak and IGT can mutually decide at any time to terminate the merger
agreement without completing the merger. Also, either Sodak or IGT can decide to
terminate the merger agreement in a number of situations, including the final
denial of a needed regulatory approval or the failure to complete the merger by
December 31, 1999. However, if the failure to complete the merger is due to a
failure to obtain regulatory approval and the approval is still pending, either
party may extend the termination date to March 31, 2000.

    If we terminate the merger agreement under certain circumstances, we will
have to pay IGT a termination fee of $8 million.

    Whether or not the merger is completed, the parties will each pay their own
fees and expenses, except that they have divided or will divide evenly the costs
and expenses of printing and mailing this document, the fees paid to the
Securities and Exchange Commission in connection with filing this document and
the fees paid in connection with filing the Hart-Scott-Rodino premerger
notification forms with the FTC and the DOJ.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (page 20)

    The merger will be a taxable transaction to you. You will recognize taxable
gain or loss in the merger in an amount determined by the difference between the
cash merger consideration received and your tax basis in the Sodak common stock
canceled for that cash payment. The gain or loss will be a capital gain or loss
if the Sodak common stock is a capital asset in your hands and will be a
long-term capital gain or loss if your holding period exceeds one year.

INTERESTS OF CERTAIN PERSONS IN THE MERGER (page 33)

    In considering the recommendation of the Sodak Board of Directors to approve
the merger, you should be aware that some of our directors and executive
officers have interests in the merger that are in addition to the benefits they
will receive as stockholders. These interests exist because of rights under
benefit and compensation plans maintained by Sodak and, in the case of some of
the executive officers, under employment agreements with Sodak that may provide
some of our executive officers with severance benefits if their employment is
terminated following the merger. Additionally, some of our compensation and
benefit plans provide for accelerated vesting and distribution of stock options
and restricted stock as a result of the merger.

    Following the merger, IGT will indemnify the officers and directors of Sodak
for some events occurring before the merger. IGT has also agreed to maintain
directors' and officers' liability insurance covering Sodak's directors and
officers for a period of six years.

    If we had been unable to sell our interest in the Louisiana joint venture,
IGT would have had the right to require Roland Gentner and Tom Celani, two of
our directors and major stockholders, to purchase all of our interest in the
joint venture and assume all of our responsibilities under the related joint
venture documents. As a result of the sale of our interest in the Louisiana
joint venture in accordance with the terms of the merger agreement, the put
right will not be exercised.

    The members of the Sodak Board of Directors knew about these additional
interests and considered them when they approved the merger.

                              THE SPECIAL MEETING

GENERAL

    This document is furnished in connection with the solicitation of proxies
from the holders of Sodak common stock by Sodak's Board for use at the special
meeting. This document and the accompanying form of proxy are first being mailed
to Sodak stockholders on or about June 2, 1999.

TIME AND PLACE

    The special meeting will be held at the Rushmore Plaza Holiday Inn, 505
North 5(th) Street, Rapid City, South Dakota on Wednesday, July 7, 1999, at
11:00 a.m., local time.

MATTERS TO BE CONSIDERED

    At the special meeting, Sodak stockholders will be asked to consider and

on other matters that may properly be raised at the special meeting. It is not
anticipated that any other matters will be raised at the special meeting.

PROXIES

    The accompanying form of proxy is for use at the special meeting if a Sodak
stockholder will be unable or does not wish to attend in person. All shares of
Sodak common stock represented by proxies properly received prior to or at the
special meeting and not revoked will be voted in accordance with the
instructions indicated in the proxies. If no voting instructions are indicated
on a proxy, the shares represented by that proxy will be voted in favor of the
merger agreement proposal. Any proxy given on the accompanying form may be
revoked by the person giving it at any time before it is voted. Proxies may be
revoked, or the votes reflected in the proxy changed, by:

    - submitting, including by telecopy, to the Secretary of Sodak, before the
      vote is taken at the special meeting, a written notice of revocation
      bearing a later date than the date of the proxy;

    - submitting a properly executed later-dated proxy relating to the same
      shares; or

    - attending the special meeting and voting in person.

    In order to vote in person at the special meeting, Sodak stockholders must
attend the meeting and cast their votes in accordance with the voting procedures
established for the meeting. Attendance at the meeting will not in and of itself
constitute a revocation of a proxy. Any written notice of revocation or
subsequent proxy must be sent so as to be delivered at or before the vote is
taken at the special meeting as follows:

    Sodak Gaming, Inc.
    5301 S. Highway 16
    Rapid City, South Dakota 57701
    Facsimile: (605) 355-5068
    Phone: (605) 341-5400
    Attention: Michael Diedrich, Vice President and Legal Counsel.

    Sodak stockholders who require assistance in changing or revoking a proxy
should contact Michael Diedrich at the address or phone number provided above.

    Sodak stockholders should not send in any stock certificates with their
proxy cards. A letter of transmittal with instructions for the surrender of
certificates representing Sodak common stock will be mailed by IGT to Sodak
stockholders as soon as practicable after the effective time of the merger.

                                       6
<PAGE>
SOLICITATION OF PROXIES

    The cost of soliciting the proxies from Sodak stockholders will be borne by
Sodak, except that Sodak and IGT have borne or will bear equally the cost of
printing and mailing this document, the filing fees related to the filing of
this document with the SEC and those related to the filing of the
Hart-Scott-Rodino forms with the FTC and the DOJ. In addition to solicitation by
mail, arrangements will be made with brokerage houses and other custodians,
nominees and fiduciaries to send the proxy materials to beneficial owners and
Sodak will, upon request, reimburse the brokerage houses and custodians for
their reasonable expenses in so doing.

RECORD DATE; VOTING RIGHTS; QUORUM; VOTE REQUIRED

    The Board of Directors has fixed the close of business on May 26, 1999 as
the record date for Sodak stockholders entitled to notice of and to vote at the
special meeting.

    The only outstanding voting securities of Sodak are the shares of common
stock. Only holders of record of Sodak common stock on the record date are
entitled to notice of the special meeting, and to vote at the special meeting.
Each holder of record, as of the record date, of shares of Sodak common stock is
entitled to cast one vote per share on the merger agreement proposal.

    The presence in person or by proxy of holders of a majority of the shares
entitled to vote at the special meeting will constitute a quorum for the
transaction of any business. In case a quorum is not present, the meeting may be
adjourned from time to time without notice other than an announcement at the
time of the adjournment of the date, time and place of the adjourned meeting.

    Approval and adoption of the merger agreement and the merger requires the
affirmative vote of the holders of a majority of the Sodak common stock
outstanding on the record date. Accordingly, a proxy marked "abstain" will have
the effect of a vote against the proposal. Similarly, the failure of a Sodak
stockholder to return a proxy or attend the special meeting to vote in person
will have the effect of a vote against the merger agreement proposal. The Sodak
Board urges you to complete, date and sign the accompanying proxy and return it
promptly in the enclosed, postage-paid envelope.

    On the record date, there were approximately 22,814,140 shares of Sodak
common stock outstanding and entitled to vote at the special meeting, held by
approximately 273 holders of record. On the record date, the directors and
executive officers of Sodak and their affiliates beneficially owned and were
entitled to vote 12,133,605 shares of Sodak common stock, or approximately 53%
of the shares of Sodak common stock outstanding on the record date.

    Three directors and executive officers and one other major stockholder, who
collectively own approximately 52% of the outstanding Sodak common stock, have
entered into voting agreements with IGT in which they agree, among other things,
to be present at the special meeting and to vote for the merger agreement
proposal. The voting agreements are described in more detail under the heading
"The Merger Agreement and Related Agreements--Irrevocable Proxy and Voting
Agreements below. Accordingly, if those voting agreements are not terminated, it
is virtually assured that a quorum will be present at the special meeting and
that the merger agreement and the merger will be approved and adopted.

                                   THE MERGER

PARTIES TO THE MERGER

    IGT AND SAC

    IGT is one of the largest manufacturers of computerized casino gaming
equipment and products and operators of proprietary gaming systems in the world.
IGT manufactures a broad range of microprocessor-based gaming machines,
including spinning reel slot machines and video gaming machines. IGT also
develops and operates electronically-linked, inter-casino proprietary gaming
machine systems, known as wide area progressive systems. In addition, IGT has
developed and sells systems for video lotteries and casino management systems.

    SAC, Inc. is a wholly-owned subsidiary of IGT organized for the sole purpose
of effecting the merger. It has not conducted any business operations and, upon
completion of the merger, its separate corporate existence will cease.

    ALL INFORMATION CONTAINED IN THIS DOCUMENT CONCERNING IGT OR SAC HAS BEEN
SUPPLIED BY IGT AND HAS NOT BEEN INDEPENDENTLY VERIFIED BY SODAK.

    SODAK

    Sodak is a leading distributor and financier of gaming equipment and a broad
range of gaming-related products and services, and is a provider of wide area
progressive systems, primarily to Native American casinos and primarily
involving gaming equipment manufactured by, and wide area progressive systems
developed by, IGT under exclusive agreements. In addition, we currently operate
the MISS MARQUETTE riverboat casino entertainment facility in Marquette, Iowa.
Other business activities include a participation in Harrah's Entertainment
Inc.'s management fee from Harrah's Phoenix Ak-Chin casino in Arizona and income
from financing product sales and casino ventures.

BACKGROUND OF THE MERGER

    Sodak and IGT have had extensive business dealings for many years. Since
1989, Sodak has had a distribution agreement with IGT giving Sodak the right to
distribute IGT manufactured or assembled gaming devices and slot machines. Under
the current agreement, Sodak has the exclusive right to distribute those
products in North Dakota, South Dakota, Wyoming and Native American reservations
in the United States, subject to some exceptions. Additionally, since 1993,
Sodak has had an exclusive distributor agreement with IGT that allows Sodak to
provide and market IGT's proprietary wide area progressive systems to Native
American casinos.

    In February, 1998, with the approval of Sodak's Board of Directors, Salomon
Smith Barney contacted G. Thomas Baker, IGT's President and Chief Operating
Officer, to explore the possibility of an acquisition of Sodak by IGT. On March
13, 1998, IGT and Sodak executed a confidentiality agreement to facilitate
discussions concerning a possible transaction. After preliminary discussions,
IGT decided not to proceed with an acquisition at that time.

    During the spring of 1998, Sodak conducted a review of its business and
prospects. In June, Sodak announced a corporate restructuring designed to
refocus the company on its core businesses-- distributing gaming equipment and
operating wide area progressive systems for Native American casinos. Sodak
determined to continue its ownership in the MISS MARQUETTE riverboat complex and
to develop a riverboat complex with Hollywood Casino Corporation in Shreveport,
Louisiana.

    In connection with the restructuring, we engaged Salomon Smith Barney to
market our interests in gaming operations in Latin America. We successfully
completed the divestiture of our Brazil operation in late July, 1998 and our
Peru and Ecuador operations in December, 1998.

                                       8
<PAGE>
    In late October, 1998, Salomon Smith Barney reinitiated discussions with IGT
about a potential transaction with Sodak. It was becoming apparent that a Native
American gaming referendum would pass in California. In November, 1998, this
referendum indeed passed, increasing the likelihood of gaming in California.

    In mid-November, IGT contacted Salomon Smith Barney to indicate IGT's
interest in again exploring the possibility of a transaction with Sodak. On
December 16, 1998, Roland Gentner, the Chief Executive Officer of Sodak,
discussed the possibility of exploring a transaction with IGT with the Sodak
Board of Directors, and summarized his and Salomon Smith Barney's discussions
with IGT. The Sodak Board encouraged Mr. Gentner to continue discussions and
appointed a special negotiating committee consisting of Mr. Gentner, Colin Reed
and Ronnie Lopez to consult and continue these discussions with IGT and to
report periodically to the Board members. Sodak formally engaged Salomon Smith
Barney in early December, 1998, to advise and assist the company in connection
with the possible transaction.

    During late December, 1998, and early January, 1999, Sodak and IGT and their
legal advisors and Salomon Smith Barney had numerous discussions about possible
structures for a transaction. Preliminary negotiations included discussion of a
possible transaction in which IGT would acquire Sodak for a combination of cash
and IGT stock. On January 10, 1999, counsel for IGT distributed a draft merger
agreement for a possible transaction structured in that way. This transaction
structure presented a number of difficult structural issues including the amount
and make-up of the consideration. As discussions progressed, IGT indicated a
willingness to increase the aggregate consideration it would be willing to offer
to approximately $10.00 per share, and possibly even $10.25 per share, if Sodak
would agree to a deal for all cash consideration. The negotiators for Sodak
expressed a willingness to discuss an all-cash deal and negotiations proceeded.
Representatives of IGT also commenced a due diligence review of Sodak.

    During this period, the members of the special negotiating committee
discussed the status of negotiations and the Board met frequently by
teleconference to receive updates on the discussions and advice from Salomon
Smith Barney and counsel. On January 22, 1999, the Sodak Board met with its
legal advisors and Salomon Smith Barney to discuss the status of negotiations,
strategy and the duties of the Board. Salomon Smith Barney presented certain
financial analyses intended to assist the Board in its deliberations. At that
point, there were a number of issues remaining for discussion between the
parties and the Sodak Board encouraged the negotiating committee to continue to
pursue discussions. However, discussions with IGT temporarily broke down as
these issues resulted in an impasse. Subsequently talks were re-initiated and
IGT stated it would agree to pursue further discussions only if the transaction
could be done at no more than $10.00 per share. Sodak's negotiators agreed to
continue the discussions.

    Representatives of IGT and Sodak and their legal advisors and Salomon Smith
Barney continued to have frequent discussions and negotiations throughout
February, 1999. During this period, representatives of IGT continued their due
diligence investigations of Sodak. IGT insisted that the transaction could be
pursued only if the four significant stockholders of the company represented on
the Sodak Board--Mr. Gentner, Michael Wordeman, Harrah's Operating Company, Inc.
and Thomas Celani--agreed to support the transaction, including by granting a
proxy and agreeing to vote in favor of the deal. Following discussions, and
negotiation of the terms of the voting agreements, the four stockholders agreed
to do so. IGT also insisted that a means be agreed upon to deal with Sodak's
non-core businesses, principally the MISS MARQUETTE riverboat complex and the
Louisiana joint venture, which IGT would not be permitted to own under existing
gaming regulations. One solution that IGT suggested with respect to the
Louisiana joint venture was for the four stockholders to agree to assume all of
Sodak's responsibilities and obligations. Messrs. Gentner and Celani, neither of
whom wanted to acquire the Louisiana joint venture, agreed that, if Sodak made
an effort to dispose of the joint venture interest and failed, they would permit
IGT to put the interest, including all the obligations related to

                                       9
<PAGE>
the joint venture, to them. Mr. Wordeman and Harrah's did not agree to the put.
The parties further agreed that Sodak would pursue the sale of the MISS
MARQUETTE.

    Another condition to IGT's proceeding with the transaction was that Mr.
Gentner agree to renegotiate the terms of his employment agreement to reduce
significantly his benefits and that several other officers of Sodak enter into
employment agreements to provide for their continued employment following the
merger. During this time period, discussions were undertaken with these
employees, several of whom had been unaware of the merger discussions to this
point. The terms of Mr. Gentner's employment agreement and those of the other
employees were negotiated at this time. Finally, IGT insisted that Mr. Gentner
and Mr. Wordeman enter into non-competition agreements prohibiting competition
with Sodak and IGT after completion of the merger. The terms of these agreements
were negotiated extensively. The merger agreement and the related transaction
documents were further negotiated and substantially completed during late
February and early March, 1999.

    On March 9 and 10, 1999, the Sodak Board of Directors met again with its
legal advisors and Salomon Smith Barney. At this meeting, representatives of
Salomon Smith Barney and Sodak's legal advisors updated the Board on the
developments since the last meeting. Sodak's legal advisors reviewed with the
Board the terms of the proposed agreements relating to the transaction and again
reviewed the duties of the Board in considering the transaction. Salomon Smith
Barney made a financial presentation. The meeting was adjourned on March 9 to
permit further negotiations of the various transaction agreements, which
continued on March 10. When the meeting resumed, Sodak's legal advisors reviewed
with the Board the updated terms of the various agreements. Salomon Smith Barney
delivered its oral opinion to the effect that, as of March 10, 1999, the $10.00
per share merger consideration was fair to Sodak's stockholders, from a
financial point of view. After further discussion and deliberation, the Sodak
Board of Directors unanimously determined that the merger agreement and the
merger were in the best interests of Sodak and its stockholders and authorized
and approved the merger agreement, the related transaction agreements, the
merger and the other transactions contemplated by the agreements and resolved to
recommend that stockholders vote to approve and adopt the merger agreement and
the merger.

    The merger agreement, the voting agreements, the non-competition agreements
and the employment agreements with Mr. Gentner, Michael Beck, Don Gromer, Knute
Knudson, John Sears, David Salter, Clayton Trulson and Rollie Hill were signed
late in the day on March 10, 1999, and a joint press release announcing the
transaction was issued prior to the opening of trading on the Nasdaq National
Market on March 11, 1999.

REASONS FOR THE MERGER; RECOMMENDATION OF SODAK BOARD

    The Board of Directors of Sodak believes that the merger is in the best
interests of Sodak and its stockholders, and unanimously approved the merger
agreement and the merger and recommends the approval and adoption of the merger
agreement and the merger by Sodak's stockholders. In reaching this decision, the
Board of Directors consulted with Sodak management and with Sodak's financial
and legal advisors and considered a variety of factors, including the following
material factors:

    - The Board's belief that IGT is an attractive and strong merger partner
      because of the existing strong business relationship with IGT. A majority
      of Sodak's revenue is generated from distributing and operating IGT's wide
      area progressive systems and distributing IGT gaming equipment and
      proprietary software to Native American casinos through exclusive
      agreements with IGT.

    - The Board's belief that alignment with IGT is a natural progression of the
      corporate restructuring set in motion in June, 1998, to focus on our core
      business.

                                       10
<PAGE>
    - The earnings, operations, financial condition and business prospects of
      Sodak, including the uncertainty of renewal of our exclusive agreements
      with IGT.

    - The current and prospective environment in which Sodak operates, including
      economic conditions and the competitive environment of the gaming
      industry.

    - A review of the possible alternatives to a sale of Sodak, including the
      prospects of continuing to operate Sodak as an independent company. We
      considered the value to the stockholders of these alternatives, the timing
      and likelihood of achieving value from these alternatives, and the
      possibility that Sodak's future stock price might not have a present value
      greater than the consideration to be paid in the merger.

    - The opportunity for Sodak stockholders to realize a premium over recent
      market prices for their shares.

    - The presentation by Salomon Smith Barney, its analyses of the value of
      Sodak and its opinion dated as of March 10, 1999 that, as of the date of
      the opinion, the merger consideration was fair from a financial point of
      view to Sodak's stockholders.

    - The opportunities created by combining Sodak with IGT, including the
      Board's belief that this combination was in the best interest of our
      employees, customers and the communities we serve.

    - The ability to complete the merger, including, in particular, the
      likelihood of obtaining regulatory approval and the provisions of the
      merger agreement regarding IGT's and Sodak's obligations to pursue the
      regulatory approvals.

    - The requirement that we divest the MISS MARQUETTE riverboat complex and
      our 50% joint venture interest in developing a gaming riverboat in
      Shreveport, Louisiana.

    - The terms of the merger agreement, as negotiated, including IGT's
      agreement to pay a termination fee if it fails to raise the financing
      necessary for the merger, our ability to respond to, and to accept, an
      unsolicited higher offer if consistent with the Board's fiduciary
      responsibilities and the requirement that we pay a termination fee in
      those circumstances.

    - The interests of Sodak's officers and directors that are different from or
      in addition to the interests of Sodak stockholders generally.

    - The willingness of Sodak's four largest stockholders to approve the merger
      and to execute voting agreements supporting the deal.

    The above summary of the information considered and factors discussed by the
Board is not meant to be exhaustive, but includes the material matters
considered by the Board. In reaching its determination to approve the merger
agreement and the merger, the Board did not assign any relative or specific
weight to the factors, and individual directors may have considered various
factors differently. The Board considered all of the factors as a whole and
considered the factors in their totality to be favorable to and to support the
decision to approve the merger agreement and the merger and to recommend them to
Sodak's stockholders. The Board relied on the experience and expertise of
Salomon Smith Barney, its financial advisor, for quantitative analysis of the
financial terms of the merger.

OPINION OF FINANCIAL ADVISOR

    At the meeting of the Board of Directors of Sodak held on March 9 and 10,
1999, Salomon Smith Barney delivered its oral opinion, which was subsequently
confirmed in a written opinion dated March 10, 1999, to the effect that, as of
that date, the merger consideration was fair to Sodak's stockholders from a
financial point of view.

                                       11
<PAGE>
    Sodak stockholders are urged to read the Salomon Smith Barney opinion in its
entirety for information with respect to the procedures followed, assumptions
made, matters considered and limits of the review undertaken by Salomon Smith
Barney in rendering its opinion. References to the opinion in this document and
the summary of the opinion included below are qualified in their entirety by
reference to the full text of the opinion, which is included as Appendix B to
this document. The Salomon Smith Barney opinion does not constitute a
recommendation concerning how holders of Sodak common stock should vote on the
merger agreement proposal.

    In connection with rendering its opinion, Salomon Smith Barney reviewed
publicly available information concerning Sodak and other financial information
concerning Sodak, including financial forecasts, that were provided to Salomon
Smith Barney by Sodak. Salomon Smith Barney discussed the past and current
business operations, financial condition and prospects of Sodak with officers
and employees of Sodak. Salomon Smith Barney also considered other information,
financial studies, analyses, investigations and financial, economic and market
criteria that it deemed relevant.

    In its review and analysis and in arriving at its opinion, Salomon Smith
Barney assumed and relied upon the accuracy and completeness of the information
provided by Sodak and reviewed by Salomon for purposes of its opinion, and
Salomon Smith Barney did not assume any responsibility for independent
verification of that information. Without limiting the generality of the prior
sentence, Salomon Smith Barney relied upon the accuracy of information provided
to it by Sodak relating to the rights of IGT under specified circumstances to
terminate certain material contracts between Sodak and IGT. With respect to the
financial forecasts prepared by Sodak, Salomon Smith Barney was advised by the
management of Sodak that those forecasts were reasonably prepared on bases
reflecting its best currently available estimates and judgments, and Salomon
Smith Barney expressed no opinion with respect to those forecasts or the
assumptions on which they were based. Salomon Smith Barney did not assume any
responsibility for any independent evaluation or appraisal of any of the assets
(including properties and facilities) or liabilities of Sodak. Salomon Smith
Barney was not asked to, and did not, solicit other proposals to acquire Sodak.

    The Salomon Smith Barney opinion is necessarily based upon conditions as
they existed and could be evaluated on the date of the opinion. The opinion does
not address Sodak's underlying business decision to effect the merger, and it
does not express any view on the effect on Sodak of the merger and related
transactions. The opinion is directed only to the fairness, from a financial
point of view, to the Sodak stockholders of the merger consideration.

    The following is a summary of the report presented on March 9, 1999, to our
Board of Directors by Salomon Smith Barney in connection with the Board's
consideration of the proposed merger. The summary of the financial analyses
includes information presented in tabular format. IN ORDER TO UNDERSTAND FULLY
THE FINANCIAL ANALYSES USED BY SALOMON SMITH BARNEY, THESE TABLES MUST BE READ
TOGETHER WITH THE TEXT OF EACH SUMMARY. THE TABLES ALONE DO NOT CONSTITUTE A
COMPLETE DESCRIPTION OF THE FINANCIAL ANALYSES.

    OVERVIEW OF VALUATION METHODOLOGIES

    Salomon Smith Barney prepared a valuation of Sodak using several
methodologies, including discounted cash flow analysis, public company
comparables analysis, comparable transactions analysis and a sum of the parts
analysis. Each of these methodologies was used to generate a reference range for
the value of the Sodak common stock, which was then compared to the $8.25 per
share price of Sodak common stock as of March 5, 1999 and the $10.00 per share
merger consideration as part of Salomon Smith Barney's evaluation of the
fairness of the merger consideration. The following table represents a
compilation of implied reference ranges derived using several different
valuation methodologies. THIS TABLE IS NOT INTENDED TO PROVIDE A COMPLETE
UNDERSTANDING OF THE RESULTS OF EACH OF THE ANALYSES EMPLOYED, AND THE TABLE
MUST BE READ TOGETHER WITH THE TEXTUAL DESCRIPTION OF EACH PROCEDURE SET FORTH

    IMPLIED TRANSACTION PREMIUMS

    Salomon Smith Barney reviewed implied transaction premiums using a range of
prices per share of Sodak common stock for the 12-month period ended March 5,
1999. Salomon Smith Barney noted that the merger consideration represented a
premium of:

    - 21.2% to the closing stock price on March 5, 1999, of $8.25;

    - 17.2% to the 30-day trailing average closing stock price from March 5,
      1999, of $8.53;

    - 40.4% to the closing stock price of $7.13 on November 6, 1998, after the
      passage of Proposition 5 in California;

    - 90.5% to the 52-week trading low of $5.25, which occurred on October 8,
      1998; and

    - 3.2% to the 52-week trading high of $9.69, which occurred on January 29,
      1999.

    HISTORICAL STOCK TRADING ANALYSIS

    Salomon Smith Barney reviewed the historical trading prices and the
historical trading volumes of Sodak common stock from February 26, 1998, to
February 26, 1999. This review indicated that 100% of the trading activity
during that time had occurred at prices below the merger consideration price of
$10.00. Salomon Smith Barney also noted that the turnover of Sodak's common
stock from February 26, 1998, to February 26, 1999, had encompassed 72% of the
total shares outstanding and 154% of the public float.

    DISCOUNTED CASH FLOW ANALYSIS

    Using a discounted cash flow methodology, Salomon Smith Barney calculated
the present value of the projected future cash flows for Sodak (without giving
effect to the merger or any synergy estimates expected to be realized as a
result of the merger). The discounted cash flow analysis of Sodak was based on
the operating plan approved by our Board in December 1998 and on a revised
operating plan subsequently prepared by Sodak management. In addition, Salomon
Smith Barney analyzed two

                                       13
<PAGE>
sensitivities to the revised operating plan which reflected the potential impact
of the termination of Sodak's equipment distribution and wide area progressive
agreements with IGT.

    The first sensitivity case assumed that Sodak's equipment distribution
agreement with IGT was not renewed beyond its current term of 2001, but that the
wide area progressive agreement remained in place and Sodak continued to earn
royalties in perpetuity from the installed base at December 31, 2001. The second
sensitivity case assumed that Sodak's equipment distribution agreement was not
renewed beyond 2001 and that the wide area progressive agreement was terminated
simultaneously, causing the wide area progressive royalties to cease. The
calculations for these two sensitivity cases were performed without any
replacement of the revenues lost with respect to the terminated agreements from
any other potential sources.

    Under each case, Salomon Smith Barney aggregated the present value of the
free cash flows over the applicable forecast period with the present value of
the range of terminal values described below. As part of the discounted cash
flow analysis, Salomon used discount rates ranging from 11.0% to 13.0%. The
range of terminal values was calculated by applying multiples ranging from 6.0
times to 7.0 times Sodak's earnings before interest and taxes, or EBIT, for the
last year of the forecast period. The discounted cash flow analyses based on the
cases considered resulted in ranges of values per share of Sodak common stock as
follows:

    COMPARABLE PUBLIC COMPANIES ANALYSIS

    Salomon Smith Barney reviewed publicly available financial and operating
information of the following six public companies:

    - Anchor Gaming Inc.

    - Aristocrat Leisure LTD

    - Mikohn Gaming Corporation

    - Powerhouse Technologies Inc.

    - Scientific Games Holdings Corp.

    - WMS Industries Inc.

In that review, actual 1998 and estimated 1999 price/earnings multiples and firm
value/EBIT multiples were developed from Salomon Smith Barney's research, First
Call calendarized mean estimates as of March 1999 and Wall Street research EBIT
estimates. The comparable companies were chosen because they operate in the
gaming equipment industry, as does Sodak, and are also publicly traded "small
cap" companies. Salomon Smith Barney believed that the most applicable
comparable company for its review was Anchor Gaming. Salomon Smith Barney also
reviewed information relating to two "large cap" companies in the gaming
equipment industry, GTECH Holdings Corp. and IGT, but did not include them in
the analysis. For this analysis, Salomon Smith Barney used trading information
as of March 5, 1999, except for one company which had disclosed adverse
information for which the various estimates of future performance had not been
revised. For this company a more conservative approach was taken and trading
information as of February 26, 1999, was used.

    This comparable public companies analysis resulted in values ranging from
$5.00 to $8.75 per share of Sodak common stock.

    COMPARABLE TRANSACTIONS ANALYSIS

    Using publicly available information, Salomon Smith Barney reviewed five
transactions in the gaming equipment industry. These transactions are presented
in the following table:

Alliance Gaming Corp.                                     Bally Gaming
</TABLE>

The review showed that for these transactions the acquisition value as a
multiple of earnings before interest, taxes, depreciation and amortization based
on the 12 months prior to the relevant acquisition ranged from 4.6x to 7.4x,
with a median of 6.1x. This comparable transactions analysis resulted in values
ranging from $6.00 to $8.50 per share of Sodak common stock.

    SUM OF THE PARTS ANALYSIS

    Using both publicly available information and information provided by Sodak
management, Salomon Smith Barney analyzed each of Sodak's business segments to
determine valuation ranges for each business segment separately and a valuation
range for the enterprise as a whole.

    PROGRESSIVE DISCOUNTED CASH FLOW ANALYSIS.  Using a discounted cash flow
methodology, Salomon Smith Barney calculated the present value of the projected
future cash flows for Sodak's wide area progressive business segment (without
giving effect to the merger or any synergy estimates expected to be realized as
a result of the merger). This analysis was based on the revised operating plan
prepared by Sodak's management. Salomon Smith Barney aggregated the present
value of the free cash flows over the applicable forecast period with the
present value of the range of terminal values described below. As part of this
analysis, Salomon used discount rates ranging from 11.0% to 13.0%. The range of
terminal values was calculated by applying multiples ranging from 7.5x to 8.5x
the segment's EBIT for the last year of the forecast period.

    PROGRESSIVE COMPARABLE COMPANIES.  Salomon Smith Barney reviewed publicly
available financial and operating information of the following four public
companies:

    - Anchor Gaming Inc.

    - GTECH Holdings Corp.

    - IGT

    - Powerhouse Technologies Inc.

In the review, actual 1998 and estimated 1999 and 2000 price/earnings multiples
and firm value/EBIT multiples were developed from Salomon Smith Barney's
research, First Call calendarized mean

                                       15
<PAGE>
estimates as of March 1999 and Wall Street research EBIT estimates. The
comparable companies were chosen because they operate systems similar to Sodak's
wide area progressive systems, and are also publicly traded. For this analysis
Salomon Smith Barney used trading information as of March 5, 1999, except for
two companies which had disclosed adverse information for which the various
estimates of future performance had not been revised. For these companies a
conservative approach was taken and trading information as of February 26, 1999,
was used.

    The table below sets forth some of Salomon Smith Barney's findings from its
review of these comparable companies:

</TABLE>

    These analyses of discounted cash flow and comparable public companies for
the wide area progressive segment resulted in a valuation range for the
progressive business of $4.50 to $6.00 per share of Sodak common stock.

    EQUIPMENT SALES AND FINANCING DISCOUNTED CASH FLOW ANALYSIS.  Using a
discounted cash flow methodology, Salomon Smith Barney calculated the present
value of the projected future cash flows for Sodak's gaming equipment sales and
financing segment (without giving effect to the merger or any synergy estimates
expected to be realized as a result of the merger). This analysis was based on
the revised operating plan prepared by Sodak's management. Salomon Smith Barney
aggregated the present value of the free cash flows over the applicable forecast
period with the present value of the range of terminal values described below.
As part of this analysis, Salomon used discount rates ranging from 11.0% to
13.0%. The range of terminal values was calculated by applying multiples ranging
from 6.0x to 7.0x the segment's EBIT for the last year of the forecast period.

    EQUIPMENT SALES AND FINANCING COMPARABLE COMPANIES.  Salomon Smith Barney
reviewed certain publicly available financial and operating information of the
following three public companies:

    - Anchor Gaming Inc.

    - Aristocrat Leisure LTD

    - IGT

In the review, actual 1998 and estimated 1999 and 2000 price/earnings multiples
and firm value/EBIT multiples were developed from Salomon Smith Barney's
research, First Call calendarized mean estimates as of March 1999 and Wall
Street research EBIT estimates. The comparable companies were chosen because
they operate in the gaming equipment sales and financing industry, as does
Sodak, and are also publicly traded. For this analysis Salomon Smith Barney used
trading information as of March 5, 1999, except for two companies which had
disclosed adverse information for which the various estimates of future
performance had not been revised. For these companies a more conservative
approach was taken, and trading information as of February 26, 1999, was used.

    These analyses of discounted cash flow and comparable public companies for
the equipment sales and financing business segment resulted in a valuation range
for the equipment sales and financing business of $3.50 to $5.00 per share of
Sodak common stock.

    COMPARABLE RIVERBOAT TRANSACTIONS.  Salomon Smith Barney reviewed certain
publicly available information on ten transactions, including pending deals,
involving private acquisitions of riverboat assets from December 1996 to March
5, 1999. The table below sets forth some of Salomon Smith Barney's findings from
its review of these transactions:

<TABLE>
<CAPTION>
                                                                                       RANGE         MEAN        MEDIAN
                                                                                    ------------     -----     -----------
<S>                                                                                 <C>           <C>          <C>
TRAILING ENTERPRISE VALUE /EBITDA(1)..............................................   4.3x - 7.1x        6.2x         6.6x
FORWARD ENTERPRISE VALUE/EBITDA(2)................................................   3.8x - 7.0x        5.7x         5.9x
</TABLE>

- ------------------------

(1) Based on the 12 months prior to the relevant acquisition.

(2) Based on forward estimates for the next full year.

    Based on a multiple of 4.5x to 5.5x 1998 EBITDA of $8.7 million for Sodak's
primary riverboat asset, Salomon Smith Barney determined a valuation range for
this asset to be $1.45 to $1.83 per share of Sodak common stock.

    ANALYSIS OF OTHER NON-CORE SEGMENTS.  Salomon Smith Barney also reviewed
other non-core businesses of Sodak to determine valuation ranges. For Sodak's
receivables under the Ak-Chin financing contract, Salomon Smith Barney
determined the valuation range to be $0.06 to $0.13 per share based on the net
present value of income over the remaining life of the contract, discounted at a
rate of 10.5%. Salomon Smith Barney determined the valuation range for the
Shreveport Louisiana joint venture to be $0.00 to $0.22 per share based on the
abandonment of Sodak's investment or twice the amount invested to date. Salomon
Smith Barney determined the valuation range for Sodak's former Latin American
businesses to be $0.17 per share based on the cash proceeds realized in the
divestitures of these businesses, net of expenses.

    Based on its analysis of our business segments described above, Salomon
Smith Barney determined that the sum of the parts valuation ranged from $8.48 to
$12.15 per share of Sodak common stock.

    The foregoing is a summary of the material financial analyses furnished by
Salomon Smith Barney to our Board of Directors but it does not purport to be a
complete description of the analyses performed by Salomon Smith Barney or of its
presentations to our Board of Directors. The preparation of financial analyses
and fairness opinions is a complex process involving subjective judgments and is
not necessarily susceptible to partial analysis or summary description. Salomon
Smith Barney made no attempt to assign specific weights to particular analyses
or factors considered, but rather made qualitative judgments as to the
significance and relevance of the analyses and factors considered.

                                       17
<PAGE>
Accordingly, Salomon Smith Barney 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 Salomon Smith Barney, without
considering all of such analyses and factors, could create a misleading or
incomplete view of the processes underlying the analyses conducted by Salomon
Smith Barney and its opinion. With regard to the comparable public company
analysis summarized above, Salomon Smith Barney selected comparable public
companies on the basis of various factors, including the size of the public
company and similarity of the line of business; however, no public company
utilized as a comparison in such analysis, and no transaction utilized as a
comparison in the comparable transaction analyses summarized above, is identical
to Sodak, any business segment of Sodak or the merger. As a result, these
analyses are not purely mathematical, but also take into account differences in
financial and operating characteristics of the comparable companies and other
factors that could affect the transaction or public trading value of the
comparable companies and transactions to which Sodak, the business segments of
Sodak and the merger are being compared. In its analyses, Salomon Smith Barney
made numerous assumptions with respect to Sodak, industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of Sodak. Any estimates contained in Salomon Smith
Barney's analyses are not necessarily indicative of actual values or predictive
of future results or values, which may be significantly more or less favorable
than those suggested by such analyses. Estimates of values of companies do not
purport to be appraisals or necessarily to reflect the prices at which companies
may actually be sold. Because such estimates are inherently subject to
uncertainty, none of Sodak, IGT, our Board of Directors, Salomon Smith Barney or
any other person assumes responsibility if future results or actual values
differ materially from the estimates. Salomon Smith Barney's analyses were
prepared solely as part of Salomon Smith Barney's analysis of the fairness, from
a financial point of view, of the merger consideration and were provided to our
Board of Directors in that connection. The opinion of Salomon Smith Barney was
only one of the factors taken into consideration by the our Board of Directors
in making its determination to approve the merger agreement and the merger.

    Salomon Smith Barney is an internationally recognized investment banking
firm engaged, among other things, in the valuation of businesses and their
securities in connection with mergers and acquisitions, restructurings,
leveraged buyouts, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. Sodak selected Salomon
Smith Barney to act as its financial advisor on the basis of Salomon Smith
Barney's international reputation and Salomon Smith Barney's familiarity with
Sodak. Salomon Smith Barney and its predecessors and affiliates have previously
rendered investment banking and financial advisory services to Sodak and IGT,
for which they have received or will receive customary compensation. Recently,
Salomon Smith Barney acted as the lead manager in connection with IGT's private
placement of its senior notes which was completed on May 19, 1999. In addition,
in the ordinary course of its business, Salomon Smith Barney and its affiliates
(including Citigroup Inc.) may actively trade the debt and equity securities of
both Sodak and IGT for its own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.

    Pursuant to Salomon Smith Barney's engagement letter, Sodak has agreed to
pay Salomon Smith Barney a fee of approximately $2.8 million upon consummation
of the merger. Sodak has also agreed to reimburse Salomon Smith Barney for its
reasonable travel and other out-of-pocket expenses incurred in connection with
its engagement (including the reasonable fees and disbursements of its counsel)
and to indemnify Salomon Smith Barney against certain liabilities and expenses
relating to or arising out of its engagement, including certain liabilities
under the federal securities laws.

    As noted under the caption "The Merger--Reasons for the Merger;
Recommendation of Sodak Board" the fairness opinion of Salomon Smith Barney was
only one of several factors considered by the Sodak Board of Directors in
determining to approve the merger agreement and the merger. The

                                       18
<PAGE>
merger consideration was determined by arm's length negotiations between IGT and
Sodak, which consulted with Salomon Smith Barney in the process, and was not
established by Salomon Smith Barney.

REGULATORY MATTERS

    Sodak and IGT are subject to extensive gaming regulations. Sodak, IGT and
their subsidiaries hold registrations, approvals, gaming licenses or permits in
each jurisdiction in which they operate gaming activities. In each of these
jurisdictions, regulatory requirements must be complied with in order for us to
complete the merger. Generally, regulatory authorities have broad discretion in
granting, renewing and revoking gaming licenses and granting approvals.

    The following is a summary of the material regulatory approvals that we
believe must be obtained in connection with the merger. Other gaming
authorities, however, may assert that additional regulatory approvals are
required for the merger. For example, IGT has informed us that they have
received notice from the gaming authorities in the State of Washington that the
merger agreement and merger may be subject to their prior approval. If it is
determined that Washington gaming approval is required, we will file the
necessary application promptly. Similarly, if other gaming authorities assert
rights to prior approval of the merger, such approval will be sought. We cannot
be sure whether or when we will receive the regulatory approvals or that we will
obtain the approvals without conditions that would be detrimental to Sodak or
IGT.

    The merger is subject to our sale of the MISS MARQUETTE riverboat complex
and our 50% interest in the Louisiana joint venture. Our interest in the
Louisiana joint venture was divested on April 23, 1999. Our ability to divest
our interests in the MISS MARQUETTE riverboat complex is subject to the
approvals of the regulatory authorities in Iowa and, potentially, the Federal
Trade Commission and the Antitrust Division of the Department of Justice under
the Hart-Scott-Rodino Act.

SOUTH DAKOTA

    The South Dakota Commission on Gaming regulates gaming activities under the
South Dakota Limited Gaming Law. Under that law, the State of South Dakota has
delegated its right to regulate gaming within the State to the South Dakota
Commission on Gaming. The commission requires that all persons who design,
assemble, manufacture, sell, lease, or prepare a component of a slot machine
obtain a slot manufacturer or distributor license. Both Sodak and IGT have slot
manufacturer or distributor licenses. The commission also requires that all key
employees be licensed by the commission. The commission may approve or
disapprove any application for a license, depending upon whether it deems the
applicant suitable.

    Sodak is required to submit to the commission all proposed "gaming
contracts," which may include the merger agreement. The commission may approve
or deny gaming contracts and require changes in a contract before the licensee
is allowed to proceed. Additionally, the commission may require a licensee to
terminate participation in a gaming contract.

    Representatives of Sodak have contacted the South Dakota commission and are
providing information regarding the merger to the commission for its review, as
requested. The commission has not determined whether it will be necessary for
Sodak to submit a formal application for approval of the merger. We will provide
all necessary information and file any necessary application with the commission
for its review and approval as promptly as possible following any request.

IOWA

    The ownership and operation of gaming facilities in Iowa are subject to
extensive state laws and the regulations of the Iowa Racing and Gaming
Commission concerning the responsibility, financial

                                       19
<PAGE>
stability and character of gaming operators and persons financially interested
or involved in gaming operations. Anyone having a material relationship or
involvement with a gaming operation may be required to be suitable or to be
licensed. The Iowa Racing and Gaming Commission may deny an application for a
license for any cause it deems reasonable. In addition to its authority to deny
an application for a license, the Iowa Racing and Gaming Commission has
jurisdiction to disapprove a change in position by officers or key employees and
the power to require a gaming operator to suspend or dismiss officers, directors
or other key employees or sever relationships with persons who refuse to file
appropriate applications or whom the Iowa Racing and Gaming Commission finds
unsuitable.

    Additionally, anytime a licensed corporation grants an option to purchase
10% or more of its stock, the Iowa Racing and Gaming Commission may revoke the
gaming license unless any sale or transfer during the period of the license
pursuant to the option was disclosed to and approved by the Iowa Racing and
Gaming Commission. The Iowa Racing and Gaming Commission must also pre-approve
any person who acquires 5% or more of a gaming operator's equity securities.

    Our sale of the MISS MARQUETTE riverboat will be subject to a favorable
determination by the Iowa Racing and Gaming Commission of the purchasing party's
suitability and the approval of the transfer by the Iowa Racing and Gaming
Commission. We will file the necessary applications for Iowa Racing and Gaming
Commission approval promptly after we reach an agreement with a purchaser for
the MISS MARQUETTE.

LOUISIANA

    The Louisiana Riverboat Economic Development and Gaming Control Act
regulates gaming activities in the State of Louisiana. The Louisiana law
specifies certain restrictions and conditions relating to the operation of
gaming riverboats, including restricting who may own an interest in an entity
with a gaming license. No person may have an ownership interest in a Louisiana
gaming license unless they are found by the State to be suitable.

    On March 31, 1999, we entered into an agreement with HWCC-Louisiana, Inc., a
subsidiary of Hollywood Casino Corporation, to sell our interest in the
Louisiana joint venture. Under the agreement, in some circumstances, Hollywood
will reimburse Sodak for the amounts that we contributed to the joint venture.
The agreement was subject to the approval of the Louisiana Gaming Control Board
which was granted on April 20, 1999. The transfer was consummated on April 23,
1999.

HART-SCOTT-RODINO

    We have given notification and furnished information under the
Hart-Scott-Rodino Act to the Federal Trade Commission and the Antitrust Division
of the Department of Justice in order to be allowed to complete the merger. Each
of Sodak and IGT filed the required notification and report forms on May 17,
1999, which began a 30-day waiting period, during which the merger could not be
completed unless the Federal Trade Commission terminated the waiting period
early. The Federal Trade Commission granted early termination of the waiting
period on June 1, 1999, with immediate effectiveness.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES TO SODAK STOCKHOLDERS

    The following is a summary of the material United States federal income tax
consequences of the merger to the Sodak stockholders. The summary does not
purport to be a description of all tax consequences that may be relevant to
Sodak stockholders, and assumes an understanding of tax rules of general
application. It does not address special rules which may apply to Sodak
stockholders based on their tax status, individual circumstances or other
factors unrelated to the merger. Stockholders are encouraged to consult their
own tax advisors regarding the merger.

                                       20
<PAGE>
    The receipt of cash by you in exchange for Sodak common stock pursuant to
the merger will be a taxable transaction for federal income tax purposes and may
also be a taxable transaction under applicable state, local and foreign tax
laws. You will generally recognize gain or loss for federal income tax purposes
in an amount equal to the difference between (1) the amount of cash you receive
and (2) your adjusted tax basis in the Sodak common stock exchanged. The gain or
loss will be a capital gain or loss if you held the Sodak common stock as a
capital asset, and will be a long-term capital gain or loss if, at the effective
time of the merger, you held the Sodak common stock for more than one year. The
deductibility of capital losses is subject to certain limitations.

    Under the federal income tax backup withholding rules, unless an exemption
applies, IGT is required to and will withhold 31% of all payments to which you
are entitled in the merger, unless you provide a tax identification number and
you certify under penalties of perjury that the number is correct. If you are an
individual your tax identification number is your social security number. If you
are not an individual your tax identification number is your employer
identification number. You should complete and sign the substitute Form W-9,
which will be included with the letter of transmittal to be returned to the
exchange agent, in order to provide the information and certification necessary
to avoid backup withholding, unless an applicable exception exists and is proved
in a manner satisfactory to the exchange agent. Some of our stockholders
including, corporations and some foreign individuals, are not subject to these
backup withholding and reporting requirements. In order for a foreign individual
to qualify as an exempt recipient, however, he or she must submit a Certificate
of Foreign Status on Form W-8 attesting to his or her exempt status. Any amounts
withheld will be allowed as a credit against the holder's federal income tax
liability for that year.

    The foregoing discussion may not apply to Sodak stockholders who acquired
their Sodak common stock as a result of the exercise of employee stock options
or other compensation arrangements with Sodak or who are not citizens or
residents of the United States or who are otherwise subject to special tax
treatment. Each Sodak stockholder is urged to consult his, her or its tax
advisor to determine the tax consequences of the merger, including the effects
of applicable state, local, foreign or other tax laws.

APPRAISAL RIGHTS OF DISSENTING STOCKHOLDERS

    Under South Dakota law, stockholders of Sodak have the right to dissent from
the merger and obtain payment for their shares of Sodak common stock. We have
described below the steps which you must take if you wish to exercise
dissenters' rights with respect to the merger. This description is not complete.
You should read sections 47-6-23 to 47-6-23.3 and 47-6-40 to 47-6-50 of the
South Dakota Business Corporation Act. Those sections are attached as Appendix D
to this document. FAILURE TO TAKE ANY ONE OF THE REQUIRED STEPS MAY RESULT IN
TERMINATION OF YOUR DISSENTERS' RIGHTS UNDER SOUTH DAKOTA LAW. IF YOU ARE
CONSIDERING DISSENTING, YOU SHOULD CONSULT YOUR OWN LEGAL ADVISOR.

To exercise dissenters' rights you must:

    - be a stockholder of record on May 26, 1999 of the common shares of Sodak
      as to which you seek relief

    - file with Sodak, prior to the date of the special meeting, a written
      notice of your intention to demand that you be paid fair consideration for
      the shares if the merger is consummated

    - not vote your dissenting shares of Sodak common stock in favor of the
      merger

    - demand payment for your shares and deposit certificated shares as
      instructed by Sodak in the notice that we send to dissenting stockholders
      following the special meeting.

A vote against the merger and the adoption of the merger agreement will not
satisfy the requirements of a written demand for payment. If you give proper
notice of your intention to dissent from the

                                       21
<PAGE>
merger and refrain from voting at the meeting, we will give you written notice
that the merger has been approved following the special meeting. That notice
will:

    - specify where and when demand for payment should be sent

    - when and where certificates of certificated shares should be deposited in
      order to obtain payment

    - inform holders of uncertificated shares to what extent transfer will be
      restricted from the time that demand for payment is received

    - supply a form for demanding payment.

The time set for the demand and deposit will be at least 30 days from the date
that we mail the notice. If you fail to demand payment or fail to deposit any
certificated shares of Sodak common stock that you own, as required by the
notice, you will forfeit your right to receive payment for your shares under the
appraisal statute.

    Within 60 days after the final date on which our stockholders may demand
payment and deposit certificated shares, we will make a payment to each
dissenting stockholder equal to the product of the amount which we estimate to
be the fair value per share of Sodak common stock and the number of shares of
Sodak common stock held by the stockholder, with interest, if any has accrued.
Our payment will be accompanied by:

    - our balance sheet as of December 31, 1998 and statement of income for
      fiscal year ended December 31, 1998

    - our latest available interim financial statements

    - a statement of our estimate of the fair value of the shares

    - a notice of your right to demand supplemental payment

    - a copy of the South Dakota dissenters' rights statute.

    If you believe that the amount we pay in exchange for your dissenting shares
is less than the fair value of your shares or that the interest is not correctly
determined, you may send us your own estimate of the value of the shares or of
the interest and demand payment of the deficiency. If you do not file an
estimate within 30 days after we mail our initial payment to you, you will
forfeit your right to any additional payment.

    If any demand for additional payment remains unsettled within 60 days after
we have received a timely demand from you, we will file in an appropriate court
a petition requesting that the fair value of the shares and the interest be
determined by the court. All dissenters whose demands have not been settled will
be made a party to the proceeding. The court may appoint one or more appraisers
to receive evidence and recommend a decision on the question of fair value.
After a hearing without a jury, the dissenters will be entitled to judgment for
the amount by which the fair value of the shares is found to exceed the amount
that we previously paid, with interest.

    The costs and expenses of any court proceeding, including reasonable
compensation and expenses of appraisers appointed by the court, will be paid by
us, except that part of the costs and expenses may be allocated as the court
considers equitable against some or all of the dissenters who are parties and
whose actions the court determines to be arbitrary, vexatious or not in good
faith. Fees and expenses of counsel and of experts for the parties to the
proceeding will be assessed as the court considers equitable. If the court finds
that the services of counsel for any dissenter were of substantial benefit to
other dissenters similarly situated and should not be assessed against us, it
may order that reasonable counsel fees be paid out of the amounts awarded to the
dissenters who were benefited.

                                       22
<PAGE>
    Notwithstanding the above summary, we can elect to withhold payment to a
dissenting stockholder with respect to shares of Sodak common stock that a
dissenting stockholder did not own on March 11, 1999, the date of our first
announcement of the merger to the news media. Instead, upon completing the
merger, we can notify those stockholders of our estimate of the fair value per
share of the Sodak common stock, state and explain the rate of interest to be
used and offer to make payment to those stockholders only upon their agreement
to accept that payment in full satisfaction of their appraisal rights. If those
stockholders believe that the amount offered is less than the fair value of the
shares and interest, they may, within 30 days the date of mailing of our offer,
send us their own estimate of the value and the interest and demand payment. If
those stockholders fail to do so, they will forfeit their right to any
additional payment.

    One of the conditions precedent to IGT's obligation to consummate the merger
is that stockholders owning less than 10% of our outstanding common stock
exercise dissenters' rights with respect to the merger.

                  THE MERGER AGREEMENT AND RELATED AGREEMENTS

    This section describes the material provisions of the merger agreement, the
legal document that governs the merger, and the irrevocable proxy and voting
agreements. The following information, as it relates to matters contained in or
contemplated by the agreements, is qualified in its entirety by reference to the
full text of the merger agreement, which is attached as Appendix A to this
document, or the voting agreements, a form of which is attached as Appendix C to
this document, each of which is incorporated into this document. We urge you to
read the agreements in their entirety.

FORM OF MERGER

    Pursuant to the merger agreement, at the effective time of the merger, SAC
will merge with and into Sodak under South Dakota law. As a result of the
merger, the separate corporate existence of SAC will cease and Sodak, as the
surviving corporation in the merger, will continue its existence as a
wholly-owned subsidiary of IGT and will continue under the name of Sodak. As a
result of the merger, all of the properties, assets, rights, privileges,
immunities and powers of Sodak and SAC will vest in the surviving corporation,
and all liabilities, obligations and penalties of Sodak and SAC will become the
liabilities, obligations and penalties of the surviving corporation.

MERGER CONSIDERATION

    At the effective time of the merger, each share of Sodak common stock then
outstanding (other than shares of Sodak common stock owned by Sodak or any of
its subsidiaries, or IGT, SAC or any of their subsidiaries, or by stockholders
who have properly demanded and perfected their statutory dissenters' appraisal
rights) will be converted into the right to receive $10.00 cash, without
interest.

EFFECTIVE TIME

    As soon as practicable on or after the day the merger closes, on a date
specified by Sodak and IGT, which will be a date no later than the second
business day after satisfaction or waiver of the closing conditions, Sodak and
IGT will file articles of merger and all other filings required by South Dakota
law with the Secretary of State of South Dakota in the form required by South
Dakota law. The merger will become effective when the filings are made with the
Secretary of State of South Dakota or such other time as agreed by IGT and Sodak
and specified in the filings.

EXCHANGE PROCEDURES

    - As of the effective time of the merger, each certificate previously
      representing shares of Sodak common stock will represent only the right to
      receive the merger consideration upon the surrender of the certificate and
      the holder of the certificate will not have any additional rights with
      respect to the shares of Sodak common stock.

                                       23
<PAGE>
    - After the effective time of the merger, an exchange agent designated by
      IGT and reasonably acceptable to Sodak will mail to each Sodak stockholder
      that was a stockholder of record immediately prior to the effective time
      (other than holders of excluded shares of common stock) (1) a letter of
      transmittal (including a substitute Form W-9) and (2) instructions for
      surrendering certificates in exchange for the merger consideration. You
      should not return your Sodak common stock certificates with the enclosed
      proxy and should not forward those certificates to the exchange agent or
      IGT unless and until you receive a letter of transmittal following the
      effective time of the merger.

    - Upon the proper surrender of a certificate to the exchange agent, together
      with a properly completed and duly executed letter of transmittal, the
      holder of the certificate will be entitled to receive in exchange for the
      certificate a check in an amount equal to the product of the merger
      consideration and the number of shares of Sodak common stock represented
      by the certificate surrendered, less any required tax withholding. The
      surrendered certificate will be canceled. No interest will be paid or
      accrue on the merger consideration.

    - In the event of a transfer of ownership of any shares of Sodak common
      stock not registered in the transfer records of Sodak, a check for the
      merger consideration may be issued to a person other than the person whose
      name is on the certificate, if the certificate representing the Sodak
      common stock, accompanied by all documents required to evidence and effect
      the transfer, is delivered to the exchange agent properly endorsed with
      signature guarantee and the person requesting the payment pays any
      applicable transfer or other taxes.

    - If any certificate has not been surrendered one year after the effective
      time of the merger (or by an earlier date on which any payment in respect
      of the certificate would otherwise become the property of any governmental
      unit or agency), IGT may direct the exchange agent to deliver to IGT the
      funds that would have been paid upon the surrender the certificates. After
      this time, the holders of Sodak common stock that are entitled to
      surrender their certificates for the merger consideration but have not
      done so, will have only the rights of a general creditor of IGT for the
      cash payable upon the surrender of the certificate.

<PAGE>
    NO SOLICITATION OF ALTERNATIVE TRANSACTIONS

    We have agreed not to solicit or encourage, or negotiate with third parties,
in an attempt to effectuate a business combination with Sodak. However, this
does not prohibit our Board of Directors from furnishing information to or
entering into discussions or negotiations with, any person or entity that makes
an unsolicited proposal to enter into a business combination with us in a
proposal which identifies a price or a range of values to be paid in connection
with a merger, consolidation, purchase of assets, tender offer or business
combination involving Sodak or any of our subsidiaries or any proposal or offer
to acquire, in any manner, an equity interest in, any voting securities of, or a
substantial portion of the assets of Sodak or any of our subsidiaries that our
Board of Directors determines:

    - in good faith, after consultation with a financial advisor of nationally
      recognized reputation, would provide more value to the Sodak stockholders
      than the merger if the party making the proposal has demonstrated that the
      funds necessary for its proposal are reasonably likely to be available

    - in good faith, after consultation with outside counsel, that consideration
      of the proposal is necessary in order for our Board to comply with its
      fiduciary duties

if, prior to furnishing the requested information to, or entering discussions or
negotiations with, the third party, that party executes a confidentiality
agreement similar to the agreement between Sodak and IGT.

    We have agreed to notify IGT of any inquiries, offers or proposals within 24
hours of the receipt of the proposal by any of our officers, directors or
advisors. We have also agreed to keep IGT informed of the status and details of
any inquiry, offer or proposal and to answer IGT's related questions.

OTHER AGREEMENTS OF SODAK AND IGT

    LOUISIANA JOINT VENTURE

    We agreed to use our commercially reasonable efforts to sell or terminate
all of our interests in the Louisiana joint venture pursuant to documentation in
form and substance, other than price, reasonably satisfactory to IGT. Under our
agreement, we would not have been allowed to provide any consideration in
connection with the sale other than the forfeiture of our $2.5 million capital
contribution made prior to March 10, 1998, but we were not required to recover
any "positive" purchase price, unless additional money was contributed to the
joint venture after March 10, 1999 with the consent of IGT. We were required to
consult with IGT regarding our efforts to sell the joint venture interest and to
use our commercially reasonable efforts to obtain the best terms for the sale of
the interest. The minimum price obtained for our interest in the Louisiana joint
venture had to be greater than or equal to all loans, advances and additional
capital contributions to or investments made after the date of the merger
agreement, with the consent of IGT, to Sodak LA, the joint venture or any joint
venture partner. Additionally, we agreed that we would not have any further
liabilities or obligations relating to the joint venture upon the finalization
of its sale.

    On March 31, 1999, we entered into an agreement with HWCC-Louisiana, Inc., a
subsidiary of Hollywood Casino Corporation, for the sale of our interest in the
Louisiana joint venture. Under the agreement, in some circumstances,
HWCC-Louisiana will reimburse Sodak for the amounts that we contributed to the
joint venture. The agreement was subject to the approval of the Louisiana Gaming
Control Board which was granted on April 20, 1999. The transfer of our interest
to HWCC-Louisiana, which was finalized on April 23, 1999, satisfied the
condition to the merger.

    MISS MARQUETTE RIVERBOAT COMPLEX

    We also have agreed to use our commercially reasonable efforts to sell the
MISS MARQUETTE riverboat casino, together with all related shore-based
facilities, including the barge, the motel, the enclosed walkway, the parking
lot, the restaurant, the administrative offices and other entertainment
facilities on the best terms possible and to terminate all of our obligations
related to the riverboat complex. IGT has the right to approve the terms of the
sale, other than the price received, but can not unreasonably withhold its
approval. Once we find a buyer for the riverboat complex we must give IGT notice
of our intention to sell it. Upon this notice, IGT:

    - will have a right to veto the sale if IGT has obtained, or has been
      advised by a governmental agency that it is likely to obtain within 30
      days, the gaming approvals necessary for IGT to acquire the riverboat
      complex; or

    - may give us notice that it either approves of the sale or approves of the
      sale, subject to the receipt of a fairness opinion from a investment
      banking firm designated by IGT and approved by us.

If we can not obtain a fairness opinion for the proposed sale of the riverboat
complex, we will not be permitted to proceed with the sale. We have agreed to
consult with IGT regarding our ongoing efforts to sell the riverboat complex.

    We have engaged Salomon Smith Barney to assist us in the sale of the
riverboat complex. Salomon Smith Barney is currently conducting an auction
process and has had extensive discussions with several prospective buyers.
Several prospective buyers have submitted bids, and the process of selecting a
buyer and negotiating a contract is underway.

    GAMING APPROVALS

    Sodak and IGT agreed to promptly prepare and file all necessary
documentation in order to obtain as promptly as possible all necessary gaming
approvals and to comply with the terms and conditions of the gaming approvals.
Each of Sodak and IGT also agreed to use its commercially reasonable efforts to,
and to cause its officers, directors and affiliates to, file within 60 days
after March 10, 1999 all required initial applications and documents in
connection with obtaining the gaming approvals and to act reasonably and
promptly in responding to additional requests. Sodak believes that all required
initial applications and documents have been filed. We have cooperated with
regulatory authorities in connection with their review of these applications and
other filings.

    ACCESS TO INFORMATION; CONFIDENTIALITY

    Until the effective time of the merger, we have agreed to give and to cause
our subsidiaries to give IGT and its officers, employees, accountants, counsel,
financial advisors and other representatives reasonable access during normal
business hours to all of our properties, books, contracts, commitments,
personnel and records. Additionally, during this period, we will furnish
promptly to IGT:

    - a copy of each report, schedule, registration statement and other document
      filed by us during the period pursuant to the requirements of any federal
      or state securities laws

    - all other information concerning our business, properties and personnel
      that IGT reasonably requests.

Except as required by law, Sodak and IGT have agreed to treat any confidential
information of the other party in accordance with the confidentiality agreement
between IGT and Sodak and to cause its officers, employees, accountants,
counsel, financial advisers and other representatives to do the same.

                                       28

    REASONABLE EFFORTS

    Sodak and IGT each agreed to use commercially reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate the merger and the other transactions contemplated by
the merger agreement, in the most expeditious manner practicable. For example,
we each agreed to:

    - make all necessary applications, registrations and filings, including
      filings with governmental entities

    - obtain all necessary actions or nonactions, licenses, consents, approvals
      or waivers from governmental entities and other third parties

    - take all reasonable steps necessary to obtain an approval or waiver from,
      or to avoid an action or proceeding by, any governmental entity

    - execute and deliver additional instruments necessary to consummate the
      transactions contemplated by, and to fully carry out the purposes of, the
      merger agreement

    - defend any lawsuits or other legal proceedings challenging the merger
      agreement or the consummation of the transactions contemplated under it

    - use commercially reasonable efforts to fulfill all conditions to the
      respective obligations of IGT (including obtaining any financing necessary
      to consummate the merger), SAC or Sodak under the merger agreement

    - use commercially reasonable efforts to prevent the entry, enactment or
      promulgation of any threatened or pending temporary, preliminary or
      permanent injunction or other order, decree or ruling or statute, rule,
      regulation or executive order.

Notwithstanding these agreements, IGT is not obligated to take any action if
taking the action or obtaining any waiver, license, consent, approval or
exemption is reasonably likely to be materially burdensome to IGT and its
subsidiaries, taken as a whole, or to impact in a materially adverse manner the
economic or business benefits of the transactions contemplated by the merger
agreement which would render consummation of the merger inadvisable.

    NOTIFICATION

    Sodak and IGT have each agreed to give the other prompt written notice of:

    - any representation or warranty made by it in the merger agreement that is
      qualified as to materiality becoming untrue or inaccurate in any respect,
      or any representation or warranty that is not qualified as to materiality
      becoming untrue or inaccurate in any material respect

    - the failure by it to comply with or satisfy in any material respect any
      covenant, condition or agreement to be complied with or satisfied by it
      under the merger agreement

    - the occurrence of any change or event which has or can reasonably be
      foreseen to have, a material adverse effect on Sodak.

No notice given as required above will affect the representations, warranties,
covenants or agreements of the parties or the conditions to the obligations of
the parties under the merger agreement or limit or otherwise affect the remedies
available to the party receiving the notice.

the satisfaction or waiver on or prior to the closing date of a number of

      under the Hart-Scott-Rodino Act

    - the representations and warranties of Sodak and IGT that are qualified as

      by Sodak from all governmental entities and third parties in connection
      with the merger that would materially adversely affect the consummation of
      the merger or would have a material adverse effect on the continuation of
      the operations of our business or the business of the surviving
      corporation following the effective time of the merger

    - the agreement by each holder of an option to purchase Sodak common stock

      the merger consideration less the option exercise price, less any
      applicable withholding tax

    - IGT must have obtained the funds necessary to pay the aggregate merger
      consideration on terms reasonably acceptable to it

    - stockholders owning less than 10% of our outstanding common stock shall
      have exercised dissenters' rights with respect to the merger

    - Roland Gentner and certain other employees must have continued in our
      employ and will be employed by us at the effective time of the merger.

    On March 31, 1999, we entered into an agreement with HWCC-Louisiana, Inc., a
subsidiary of Hollywood Casino Corporation, for the sale of our interest in the
Louisiana joint venture. The agreement was subject to the approval of the
Louisiana Gaming Control Board which was granted on April 20, 1999. The transfer
of our interest to HWCC-Louisiana, which was finalized on April 23, 1999,
satisfied that condition to the merger.

    On May 19, 1999, IGT announced that it had completed the private placement
of $1.0 billion in aggregate principal amount of its senior notes. A portion of
the proceeds of that offering are expected to be used to finance IGT's
acquisition of Sodak. The financing raised by the private placement satisfied
the financing condition to the merger.

    The Federal Trade Commission granted early termination of the 30-day waiting
period under the Hart-Scott-Rodino Act on June 1, 1999, with immediate
effectiveness. The termination of the waiting period satisfied the condition to
the merger.

TERMINATION

    TERMINATION RIGHTS

    At any time prior to the consummation of the merger, the merger agreement
may be terminated:

    1.  by mutual written consent of the Boards of Directors of Sodak and IGT

    2.  by either party (A) upon a material breach of any representation,
       warranty, covenant or agreement set forth in the merger agreement by the
       other party or (B) if any representation or warranty of the other party
       becomes untrue, and in each case, as a result the breaching party would
       be unable to fulfill its obligation regarding the accuracy of its
       representations, warranties, agreement and covenants by December 31,
       1999; if, in each case, the party seeking to terminate is not then in
       material breach under the merger agreement

    3.  by either party if a governmental entity has issued a final and
       nonappealable order, decree or ruling or taken any other action that
       prohibits consummation of the merger

    4.  by either party if the merger has not been consummated by December 31,
       1999; provided that the failure to consummate the merger is not the
       result of a breach of a covenant or the material breach of any
       representation or warranty by the party seeking to terminate; PROVIDED
       further that if the merger has not been consummated because of a failure
       to obtain approval from a governmental entity and such approval is still
       pending, either party may extend the termination date to March 31, 2000

    5.  by either party if the approval of our stockholders is not obtained;
       provided that the terminating party is not in material breach of any of
       its obligations under the merger agreement

    6.  by IGT if our Board of Directors (A) withdraws or modifies adversely its
       recommendation of the merger to our stockholders following the receipt of
       a takeover proposal, (B) recommends a takeover proposal to our
       stockholders or (C) fails to call or hold the special meeting by reason
       of the receipt of a takeover proposal

    7.  by Sodak if, prior to the approval of our stockholders, a superior
       proposal has been made and we have determined in good faith after
       consultation with our outside counsel, that the termination of the merger
       agreement and acceptance of the superior proposal is necessary in order
       to comply with our fiduciary duties; provided that we have given IGT a
       good faith opportunity, for five business days, to amend its offer to
       provide for substantially similar terms to those of the superior proposal
       and IGT has not done so.

                                       31
<PAGE>
    TERMINATION FEES

    We have agreed to pay IGT a termination fee of $8 million if:

    - we terminate the merger agreement pursuant to the right described in
      paragraph 7 above

    - IGT terminates the merger agreement pursuant to the right described in
      paragraph 6 above

    - IGT terminates the merger agreement because we willfully and materially
      breach our agreement not to solicit, encourage, or negotiate with third
      parties, in an attempt to effectuate a business combination as described
      in this document. For more information on the limitations placed on our
      ability to negotiate a merger with a third party, see "Covenants--No
      Solicitation of Alternative Transactions."

    - any of our principal stockholders, Harrah's Operating Company, Tom Celani,
      Mike Wordeman or Roland Gentner, fails to vote in favor of the merger
      agreement proposal in breach of the voting agreement and the necessary
      approval of our stockholders is not received

    - the approval of our stockholders is not received, prior to the special
      meeting a takeover proposal is made and within 12 months from the
      termination of the merger agreement we enter into an agreement for the
      takeover proposal and within 24 months from the termination of the merger
      agreement we consummate the takeover proposal.

    Additionally, IGT agreed to pay us a termination fee of $2 million if the
merger agreement is terminated by either Sodak or IGT because the merger has not
been consummated by December 31, 1999 (March 31, 2000 if the failure to
consummate the merger has not been consummated because of a failure to obtain
approval from a governmental entity and the approval is still pending) and at
the time of the termination, IGT has not obtained the funding necessary to pay
the aggregate merger consideration on terms reasonably acceptable to IGT but all
other closing conditions have been satisfied or waived. IGT has completed the
financing necessary to finance the acquisition of Sodak.

    If we terminate the merger agreement, IGT's and SAC's exclusive remedy
against us, other than for a willful breach of our agreement not to solicit
third party takeover proposals, is our payment of a termination fee. Similarly,
the payment by IGT of a termination fee is our exclusive remedy against IGT if
the merger agreement is terminated by IGT or Sodak because the merger has not
occurred as a result of IGT's failure to obtain the funding necessary to pay the
aggregate merger consideration on terms reasonably acceptable to IGT.

AMENDMENT; WAIVER

    The merger agreement may be amended in writing by agreement of Sodak, IGT
and SAC at any time, except that after adoption of the merger agreement by our
stockholders, no amendment may be made that by law would require further
approval of the stockholders unless that approval is obtained. At any time prior
to the effective time of the merger, any party to the merger agreement may
extend the time for the performance of any of the obligations or other acts of
the other parties, waive any inaccuracies in the representations and warranties
or, subject to the amendment provisions, waive compliance with any of the
agreements or conditions contained in the merger agreement.

IRREVOCABLE PROXY AND VOTING AGREEMENTS

    Contemporaneously with the execution of the merger agreement, in order to
induce IGT to enter into the merger agreement, each of our four major
stockholders, Harrah's Operating Company, Tom Celani, Mike Wordeman and Roland
Gentner, entered into an irrevocable proxy and voting agreement with IGT. Under
the voting agreements, each of these four stockholders agreed to vote all of the
Sodak common stock owned by that stockholder in favor of the merger.
Additionally, each of these four stockholders has:

    - granted IGT a proxy to vote his or its shares as directed in the voting
      agreement

                                       32
<PAGE>
    - agreed not to pledge or otherwise dispose of any of the Sodak common stock
      owned by that stockholder

    - agreed not to solicit, initiate or encourage any takeover proposal or
      engage in negotiations or discussions with or disclose any nonpublic
      information relating to Sodak or any of its subsidiaries.

The four major stockholders collectively own approximately 52% of our common
stock. Accordingly, unless these agreements are terminated, the approval of the
merger agreement and the merger by our stockholders is virtually assured. The
voting agreements terminate upon a termination of the merger agreement.

                   INTEREST OF CERTAIN PERSONS IN THE MERGER

    Some of our officers and directors have interests in the merger that are
different from or in addition to the interest that you have as a Sodak
stockholder. As described below, some of these officers and directors will
receive benefits from the merger that are in addition to the benefits they will
receive as stockholders. Our Board of Directors was aware of these interests and
fully considered them, among other things, in adopting the merger agreement and
approving the transactions contemplated by the merger agreement.

EMPLOYMENT AGREEMENTS

    In connection with the merger agreement, Sodak entered into an employment
agreement with our chief executive officer, Roland Gentner, which supersedes Mr.
Gentner's prior employment agreement. The new agreement provides for a one year
initial term beginning on the date of the merger, and for additional one year
terms thereafter unless Mr. Gentner or Sodak chooses not to extend the
employment term. The agreement provides for an annual base salary of $400,000
and an annual cash bonus equal to a percentage of Mr. Gentner's base salary
ranging from 30% to 120%, depending on whether Sodak achieves its performance
goals for the year. At the effective time of the merger, IGT will grant Mr.
Gentner 50,000 shares of restricted IGT stock that will become vested two years
after the merger, except that Mr. Gentner will not be entitled to the shares of
restricted stock if his employment terminates due to his death or disability or,
before the one year anniversary of the date of the merger, his employment is
terminated by Sodak for "cause" (as defined in the agreement) or Mr. Gentner
resigns without "good reason" (as defined in the agreement). If Mr. Gentner is
terminated without "cause," if Mr. Gentner terminates his employment for "good
reason," or if Mr. Gentner's employment terminates as a result of his death or
disability, he is entitled to receive severance pay equal to his salary through
the end of the term plus a pro rata portion of his annual bonus. If Mr. Gentner
is terminated for "cause" or if Mr. Gentner terminates his employment without
"good reason" he is entitled to receive severance pay equal to any accrued
salary plus a pro rata portion of his annual bonus. If Mr. Gentner's employment
terminates due to his death or disability before the second anniversary of the
date of the merger, he will be entitled to receive $1,000,000 in lieu of the
50,000 restricted shares.

    In connection with the merger agreement, Sodak also entered into employment
agreements with seven other executives: Michael Beck, Don Gromer, Knute Knudson,
John Sears, David Salter, Clayton Trulson and Rollie Hill. Each agreement
provides for a one year term beginning on the date of the merger. Each agreement
specifies the executive's annual base salary as follows: Mr. Beck--$150,800; Mr.
Gromer--$114,400; Mr. Knudson--$145,600; Mr. Sears--$135,200; Mr.
Salter--$124,800; Mr. Trulson--$130,000; and Mr. Hill--$104,000. In addition,
each agreement provides that IGT will grant options (which vest over a five-year
period) to the executives to purchase a specified number of shares of common
stock of IGT as follows: Mr. Beck, Mr. Gromer, Mr. Knudson, Mr. Trulson and Mr.
Hill each will receive options to purchase 10,000 shares; Mr. Sears will receive
options to purchase 15,000 shares; and Mr. Salter will receive options to
purchase 8,000 shares. The agreements also

                                       33
<PAGE>
provide that, if the executive's employment is terminated by Sodak without
"cause" (as defined in the agreements), the executive will be entitled to
severance pay equal to one year's base salary plus, in the case of a termination
during the one year employment term, continued payments of the executive's base
salary until the end of the one year term. The agreements also contain customary
non-compete, non-solicitation and confidentiality provisions.

NON-COMPETITION AGREEMENTS

    In connection with the merger agreement, we entered into non-competition
agreements with Mr. Gentner and our former chief executive officer, Mike
Wordeman. Under the non-competition agreements, Mr. Gentner and Mr. Wordeman
each agreed not to compete with Sodak or IGT in certain lines of business
throughout the world for a period commencing at the effective time of the merger
for five years, in the case of Mr. Gentner, and, in the case of Mr. Wordeman,
for five years in
North America and Hawaii and for three years in the rest of the world. Mr.
Wordeman's restriction on competition does not apply to activities in Brazil.
Additionally, each of Mr. Gentner and Mr. Wordeman agreed not to solicit
employees or customers of Sodak or IGT.

STOCK OPTIONS AND RESTRICTED STOCK

    Each stock option outstanding immediately prior to the closing of the merger
that (1) is vested or vests as a result of the merger or (2) was granted to a
member of the Board of Directors under our 1993 Directors' Stock Option Plan,
will be canceled in exchange for a payment, in cash, to the option holder equal
to the product of (1) $10.00 less the option exercise price, multiplied by (2)
the number of shares of Sodak common stock subject to the stock option, less any
applicable withholding tax.

    In connection with the merger, options held by Sodak's executive officers
and directors will be canceled in exchange for a cash payment as follows:

A portion of the options held by each of the officers and directors listed in
the table above that were not vested will become vested as a result of the
merger. Options for which the exercise price is greater than the merger
consideration will be canceled at the effective time of the merger and are not
included in the table above.

    All outstanding shares of Sodak restricted stock, whether or not vested,
will be canceled in exchange for the merger consideration. In connection with
the merger, the 15,000 shares of Sodak restricted stock held by Mr. Gentner will
be canceled and Mr. Gentner will receive a payment equal to $150,000, less
applicable withholding taxes. These shares of restricted stock will become
vested as a result of the merger.

EMPLOYEE BENEFITS

    SODAK STOCK PURCHASE PLAN

    We agreed with IGT that all amounts contributed to the Sodak Stock Purchase
Plan that, prior to the effective time of the merger, have not been used to
purchase Sodak common stock will be used to purchase common stock immediately
prior to the effective time at a discounted purchase price provided under the
terms of the Plan. At the effective time, each share of Sodak common stock
purchased under the Stock Purchase Plan will be converted into the merger
consideration.

    CONTINUATION OF AGREEMENTS AND BENEFIT PLANS

    IGT agreed to honor all of the Sodak employment, severance, termination and
similar agreements that we identified as of the date of the merger agreement.
Each agreement will be honored until the termination of the agreement or one
year after the effective time of the merger, whichever is earlier. Additionally,
all of our employees and our subsidiaries' employees will be able to participate
in the IGT benefit plans that are provided to IGT's employees who are similarly
situated. All Sodak employees will receive credit for their service with Sodak
prior to the merger. Additionally, with some limited exceptions, waiting or
eligibility periods or exclusions for pre-existing conditions under IGT's
benefit plans will be waived.

INDEMNIFICATION

    IGT has agreed that all rights of indemnification existing at the time of
the merger in favor of our present or former directors, officers, employees and
agents under our articles of incorporation or by-laws will survive the merger
for six years from the date of its consummation. IGT further agreed that, for
six years from the consummation of the merger, IGT and the surviving corporation
will indemnify each indemnified person, to the fullest extent permitted by law,
for any claim arising out of an officer's or director's acts or omissions
occurring on or after July 1, 1998 and on or prior to the effective time of the
merger.

    Additionally, IGT agreed to maintain officer and director insurance for the
indemnitees for a period of six years from the consummation of the merger. In
lieu of purchasing that insurance, we may, with IGT's written consent, purchase
a five-year extended reporting period endorsement under our existing directors'
and officers' liability insurance coverage. If the cost of the insurance in any
year during the six-year period exceeds 150% of the premium for the policy for
the year ended June 30, 1999, then IGT will cause the surviving corporation to
provide coverage that gives our officers and directors the same protection that
IGT maintains for its officers and directors.

LOUISIANA JOINT VENTURE PUT

    If we had been unable to sell our interest in the Louisiana joint venture,
IGT would have had the right to require Roland Gentner and Tom Celani, two of
our directors and major stockholders, to purchase all of Sodak's interest in the
joint venture and assume all of our responsibilities for an amount agreed to by
IGT, Mr. Gentner and Mr. Celani. IGT asked all four of our major stockholders to
stand behind this "put" right but only Messrs. Gentner and Celani agreed to do
so. Messrs. Gentner and Celani did not want to purchase these interests, but
agreed to allow IGT to cause them to do so in order to facilitate the merger. As
a result of the sale of our interest in the Louisiana joint venture in
accordance with the terms of the merger agreement, the put will not be
exercised.

    KPMG Peat Marwick LLP serves as Sodak's independent certified public
accountant. A representative of KPMG Peat Marwick LLP will be at the Special
Meeting to answer the questions of Sodak stockholders.

                          OTHER STOCKHOLDERS MEETINGS

    We intend to hold an annual meeting of our stockholders in 1999 only if the
merger is not consummated. If an annual meeting is held, eligible Sodak
stockholders may submit proposals to be considered for stockholder action at the
annual meeting if they do so in accordance with applicable regulations of the
SEC and our by-laws. If an annual meeting is held, it is expected that a
representative of KPMG Peat Marwick LLP will be present and available to respond
to appropriate questions from stockholders. The representative will also have
the opportunity to make a statement at the annual meeting if he or she so
desires.

    AGREEMENT AND PLAN OF MERGER, dated as of March 10, 1999, among
International Game Technology, a Nevada corporation ("PARENT"), SAC, Inc., a
South Dakota corporation and a direct wholly owned subsidiary of Parent ("SUB"),
and Sodak Gaming, Inc., a South Dakota corporation (the "COMPANY").

                                   BACKGROUND

    A. The respective Boards of Directors of Parent, Sub and the Company have
determined that it is advisable and in the best interest of their respective
stockholders for Sub to merge with and into the Company (the "MERGER") and have
approved the Merger, upon the terms and subject to the conditions set forth in
this Agreement and in accordance with the South Dakota Business Corporation Act
(the "SDBCA"), whereby each issued and outstanding share of common stock of the
Company, $.001 par value per share (the "COMPANY COMMON STOCK"), other than
shares to be cancelled in accordance with Section 2.1(b), will be converted into
the right to receive $10.00 in cash (the "MERGER CONSIDERATION").

    B. The Merger requires the approval of the holders of a majority of the
outstanding shares of the Company Common Stock (the "STOCKHOLDER APPROVAL").

    C. Parent, Sub and the Company desire to make certain representations,
warranties, covenants and agreements in connection with the Merger and also to
prescribe various conditions to the Merger.

    D. Concurrently with the execution and delivery of this Agreement and as a
condition and inducement to each of Parent's and Sub's willingness to enter into
this Agreement, Harrah's Operating Company, Inc., Michael G. Wordeman, Thomas
Celani and Roland W. Gentner, the significant stockholders of the Company (the
"SIGNIFICANT STOCKHOLDERS"), have each entered into an Irrevocable Proxy and
Voting Agreement (collectively, the "VOTING AGREEMENT") with Parent dated as of
the date of this Agreement substantially in the form of Exhibit A attached
hereto, pursuant to which each Significant Stockholder has agreed, among other
things, to vote all voting securities of the Company beneficially owned by such
Significant Stockholder or for which such Significant Stockholder exercises
voting power pursuant to an irrevocable proxy in favor of approval and adoption
of this Agreement and the Merger.

                                   AGREEMENT

    In consideration of the representations, warranties, covenants and
agreements contained in this Agreement, the parties agree as follows:

Following the Merger, the separate corporate existence of Sub shall cease and
the Company shall continue as the surviving corporation (the "SURVIVING
CORPORATION") and shall succeed to and assume all the rights and obligations of
the Company and of Sub in accordance with the SDBCA.

    SECTION 1.2  CLOSING.  The closing of the Merger will take place at 2:00

                                   ARTICLE II

               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

    SECTION 2.1  EFFECT ON CAPITAL STOCK.  At the Effective Time, by virtue of
the Merger and without any action on the part of Parent, Sub, the Company or the
holders of any shares of Company Common Stock or any shares of capital stock of
Sub:

    (a) CAPITAL STOCK OF SUB. Each share of the capital stock of Sub issued and
outstanding immediately prior to the Effective Time shall be converted into one
(or such other number as may be specified by Parent at any time prior to the
Closing) fully paid and nonassessable share of common stock of the Surviving
Corporation, which shall be owned by Parent.

    (b) CANCELLATION OF TREASURY STOCK AND PARENT OWNED STOCK. Each share of
Company Common Stock that is owned by the Company or by any subsidiary of the
Company and each share of Company Common Stock that is owned by Parent, Sub or
any other subsidiary of Parent immediately prior to the Effective Time shall
automatically be cancelled and retired without any conversion thereof and no
consideration shall be delivered with respect thereto.

    (c) CONVERSION OF COMMON STOCK.

                                      A-5
<PAGE>
        (i) At the Effective Time, each share of Company Common Stock issued and
    outstanding immediately prior to the Effective Time (other than shares of
    Company Common Stock (A) owned by the Company or any subsidiary of the
    Company, or Parent, Sub or any other subsidiary of Parent or (B) held by
    stockholders ("DISSENTING STOCKHOLDERS") duly exercising appraisal rights
    pursuant to Sections 47-6-23 and 47-6-48 of the SDBCA ("DISSENTING SHARES"
    and, collectively with the shares of Company Common Stock owned by the
    Company or any subsidiary of the Company or Parent, Sub or any other
    subsidiary of Parent, the "EXCLUDED SHARES")) shall, by virtue of the Merger
    and without any action on the part of the holder thereof, be converted into
    the right to receive, without interest, the Merger Consideration.

        (ii) As of the Effective Time, all shares of Company Common Stock shall
    no longer be outstanding and shall automatically be cancelled and retired
    and shall cease to exist, and each certificate previously representing any
    such shares shall thereafter represent the right to receive cash upon
    surrender of such certificates in accordance with Section 2.2 or the right,
    if any, to require the Surviving Corporation to purchase such shares of
    Company Common Stock for their "fair value" as determined in accordance with
    Section 47-6-46 of the SDBCA. The holders of such certificates previously
    evidencing such shares of Company Common Stock outstanding immediately prior
    to the Effective Time shall cease to have any rights with respect to such
    shares of Company Common Stock as of the Effective Time except as otherwise
    provided herein or by law.

    SECTION 2.2  EXCHANGE OF CERTIFICATES.

    (a) Promptly after the Effective Time, the Exchange Agent (as defined below)
shall mail to each holder of record of Company Common Stock immediately prior to
the Effective Time (other than Excluded Shares) (i) a letter of transmittal (the
"COMPANY LETTER OF TRANSMITTAL") (which shall specify that delivery shall be
effected, and risk of loss and title to the Company certificates representing
shares of the Company Common Stock (the "CERTIFICATES") shall pass, only upon
delivery of such Certificates to the Exchange Agent and shall be in such form
and have such other provisions as Parent and the Company shall mutually agree)
and (ii) instructions for use in effecting the surrender of the Certificates in
exchange for the Merger Consideration with respect to the shares of Company
Common Stock formerly represented thereby.

    (b) At the Effective Time, Parent shall make available, or cause to be made
available to the party specified by Parent and reasonably acceptable to the
Company as the exchange agent (the "EXCHANGE AGENT"), amounts sufficient in the
aggregate to provide all funds necessary for the Exchange Agent to make payments
pursuant to Section 2.1(c)(i) hereof to holders of Company Common Stock issued
and outstanding immediately prior to the Effective Time who are to receive the
Merger Consideration. Any interest, dividends, or other income earned on the
investment of cash deposited by Parent with the Exchange Agent in accordance
with this Section 2.2(b) shall be for the account of and payable to Parent.

    (c) Upon surrender to the Exchange Agent of Certificates, together with the
Company Letter of Transmittal, duly executed and completed in accordance with
the instructions thereto, and only upon such surrender, the holder of such
Certificate shall be entitled to receive, in exchange therefor, and Parent shall
promptly cause to be delivered to such holder a check in the amount to which
such holder is entitled, after giving effect to any required tax withholdings.
The Certificates surrendered pursuant to this Section 2.2(c) shall forthwith be
cancelled. If any Certificate shall have been lost, stolen, mislaid or
destroyed, then upon (1) receipt of an affidavit of that fact from the holder
claiming such Certificate to be lost, mislaid, stolen or destroyed and an
indemnity (each in form and substance reasonably satisfactory to Parent), and
(2) if required by Parent, the posting by such person of a bond in such
reasonable amount as the Company may direct as indemnity against any claim that
may be made against it with respect to such Certificate, the Exchange Agent
shall issue to such holder the Merger

                                      A-6
<PAGE>
Consideration into which the shares represented by such lost, stolen, mislaid or
destroyed Certificate shall have been converted.

    (d) No interest will be paid or will accrue on the amount payable upon the
surrender of any Certificate. If payment is to be made to a person other than
the registered holder of the Certificate surrendered, it shall be a condition of
such payment that the Certificate so surrendered shall be properly endorsed and
otherwise in proper form for transfer, as determined by the Exchange Agent or
Parent, and that the person requesting such payment shall pay any transfer or
other taxes required by reason of the payment to a person other than the
registered holder of the Certificate surrendered or establish to the
satisfaction of the Parent or the Exchange Agent that such tax has been paid or
is not payable. One year following the Effective Time, Parent shall be entitled
to cause the Exchange Agent to deliver to it any funds (including any interest
received with respect thereto) made available to the Exchange Agent which have
not been disbursed to holders of Certificates formerly representing shares of
Company Common Stock outstanding on the Effective Time, and thereafter such
holders shall be entitled to look to the Parent only as general creditors
thereof with respect to cash payable upon due surrender of their Certificates.

    (e) In the event of a transfer of ownership of Company Common Stock which is
not registered in the transfer records of the Company, the Merger Consideration
may be paid or issued to a person other than the person in whose name the
Certificate so surrendered is registered, if such Certificate, accompanied by
all documents required to evidence and effect such transfer, shall be properly
endorsed with signature guarantee or otherwise be in proper form for transfer,
and the person requesting such payment shall pay any transfer or other taxes
required by reason of the payment of the Merger Consideration to a person other

of Parent that such tax has been paid or is not applicable.

    (f) The Merger Consideration paid upon the surrender for exchange of
Certificates in accordance with the terms of this Article II shall be deemed to
have been paid in full satisfaction of all rights pertaining to the shares of
Company Common Stock theretofore represented by such Certificates, SUBJECT,
HOWEVER, to the Surviving Corporation's obligation to pay any dividends or make
any other distributions with a record date prior to the Effective Time which may
have been declared or made by the Company on such shares of Company Common Stock
in accordance with the terms of this Agreement or prior to the date of this
Agreement and which remain unpaid at the Effective Time and have not been paid

Company shall be closed, and there shall be no further registrations of
transfers of shares of Company Common Stock thereafter on the records of the
Company.

    SECTION 2.3  NO LIABILITY.  None of Parent, Sub, the Company or the Exchange

cash otherwise payable to such holder of shares of Company Common Stock
delivered or paid to a public official pursuant to any applicable abandoned
property, escheat or similar law.

    SECTION 2.4  DISSENTERS' RIGHTS.  If any Dissenting Stockholder shall be
entitled to require the Company to purchase such stockholder's shares for their
"fair value", as provided in Chapter 47-6-46 of the SDBCA, the Company shall
give Parent notice thereof and Parent shall have the right to participate in all
negotiations and proceedings with respect to any such demands. Neither the
Company nor the Surviving Corporation shall, except with the prior written
consent of Parent, voluntarily make any payment with respect to, or settle or
offer to settle, any such demand for payment. If any Dissenting Stockholder
shall fail to perfect or shall have effectively withdrawn or lost the right to
dissent, the shares held by such stockholder shall thereupon be entitled to be
surrendered in exchange for the Merger Consideration as provided by Sections 2.1
and 2.2 hereof.

Company has made available to Parent complete and correct copies of its articles
of incorporation and by-laws and the articles of incorporation and by-laws or
other organizational documents of its subsidiaries, in each case as amended to

agreement, arrangement or undertaking. There are no outstanding contractual
obligations of the Company or any of its subsidiaries to repurchase, redeem or

    Company or any of its subsidiaries, to tax or penalty under ERISA, the Code
    or other applicable law that is material to the business of the Company and
    that has not been corrected. Neither any of such Benefit Plans nor any of

    employee or former employee of the Company or any subsidiary of the Company
    or the beneficiary or dependent of any such employee or former employee.

                                      A-13
<PAGE>
    such Returns required to be filed on or before the Effective Time. All such
    Returns are and will be true, complete and correct in all material respects.
    The Company and each of its subsidiaries has paid and discharged (or the
    Company has paid and discharged on such subsidiary's behalf) all material
    taxes due from them, other than such taxes as are being contested in good
    faith by appropriate proceedings and are adequately reserved for on the most

    upon the Company. No requests for waivers of the time to assess any taxes
    are pending. No power of attorney has been granted by the Company or any of
    its subsidiaries with respect to taxes which is currently in force. None of

    Disclosure Schedule. Except as set forth in Section 3.1(m) of the Company
    Disclosure Schedule, neither the Company nor any of its subsidiaries has

    state, local and foreign income, property, sales, excise and other taxes, of
    any nature whatsoever (whether payable directly or by withholding), together
    with any interest and penalties, additions to tax or additional amounts
    imposed with respect thereto. As used in this Section 3.1(m) only and

Agreement that are qualified as to materiality becoming untrue or (ii) any of
such representations and warranties that are not so qualified becoming untrue in
any material respect.

    SECTION 4.2  NO INCONSISTENT ACTIVITIES.

    (a) In light of the consideration given by the Board of Directors of the
Company prior to the execution of this Agreement to, among other things, the
transactions contemplated hereby, and in light of the Company's representations
contained in Section 3.1(u), the Company agrees that it shall not, nor shall it
permit any of its subsidiaries to, nor shall it authorize or permit any officer,
director or employee of, or any investment banker, attorney or other advisor or
representative of, the Company or any of its subsidiaries to, directly or
indirectly, solicit or initiate, or encourage the submission of, any Takeover
Proposal (as defined below), or participate in any discussions or negotiations
regarding, or furnish to any person any information with respect to, or take any
other action to facilitate any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Takeover Proposal;
PROVIDED, HOWEVER, that nothing in this Section 4.2 shall prevent the Company or
its Board of Directors from furnishing non-public information to, or entering
into discussions or negotiations with, another person in connection with an
unsolicited bona fide Takeover Proposal by such person, if and only to the
extent that (i) such person has made a proposal to the Board of Directors of the
Company to consummate a Takeover Proposal, which proposal identifies a price or
range of values to be paid for the outstanding securities or all or
substantially all of the assets of the Company, (ii) the Board of Directors of
the Company determines in good faith, after consultation with a financial
advisor of nationally recognized reputation, that such proposal would, if so
completed, result in a transaction that would provide greater value to the
holders of Company Common Stock than the Merger (a "SUPERIOR PROPOSAL") and that
the party making the proposal has demonstrated that the

                                      A-22
<PAGE>
funds necessary for its proposal are reasonably likely to be available, (iii)
the Board of Directors of the Company determines in good faith, after
consultation with outside counsel, that such action is necessary in order to
comply with its fiduciary duties to the Company's stockholders under applicable
law, and (iv) prior to furnishing such information to, or entering into
discussions or negotiations with, such person or entity, the Board of Directors
receives from such person an executed confidentiality agreement in form and
substance similar to the Confidentiality Agreement dated March 13, 1998 (the
"CONFIDENTIALITY AGREEMENT") between the Company and Parent.

    (b) The Company shall notify Parent orally and in writing of any inquiries,
offers or proposals with respect to a Takeover Proposal (including without
limitation the terms and conditions of such proposal, the identity of the person
or entity making it and all other information reasonably requested by Parent),
within 24 hours of the receipt thereof by an officer or director of the Company
or any advisor to the Company, shall keep Parent informed of the status and
details of any such inquiry, offer or proposal and answer Parent's questions
with respect thereto. For purposes of this Agreement, "TAKEOVER PROPOSAL" means
any proposal (whether or not in writing and whether or not delivered to the
Company's stockholders generally) for a merger, consolidation, purchase of
assets, tender offer or other business combination involving the Company or any
of its subsidiaries or any proposal or offer to acquire in any manner, directly
or indirectly, an equity interest in, any voting securities of, or a substantial
portion of the assets of, the Company or any of its subsidiaries, other than the
transactions contemplated by this Agreement. Neither the Company nor any of its
subsidiaries shall directly or indirectly, release any third party from any
confidentiality agreement, except in connection with a Superior Proposal if the
Company's Board of Directors shall have determined in good faith, after
consultation with outside counsel, that such release of any third party is
necessary in order to comply with its fiduciary duties to the Company's
stockholders under applicable law. Nothing contained herein shall prohibit the
Company from disclosing to its stockholders the statement required by Rule
14e-2(a) under the Exchange Act with respect to a Takeover Proposal by means of
a tender offer.

                             ADDITIONAL AGREEMENTS

    SECTION 5.1  PREPARATION OF THE PROXY STATEMENT; STOCKHOLDERS' MEETING.

    (a) As soon as practicable following the date of this Agreement, the Company
shall call and hold a meeting of its stockholders (the "COMPANY STOCKHOLDERS'
MEETING"), for the purpose of obtaining the Stockholder Approval. Subject to the
fiduciary duties of its Board of Directors, the Company shall use its best
efforts to solicit from its stockholders proxies, and shall take all other
action necessary or advisable to secure the vote or consent of stockholders
required by applicable law or otherwise to obtain the Stockholder Approval, and
through its Board of Directors, shall recommend to its stockholders the
obtaining of the Stockholder Approval. As promptly as practicable after the
execution of this Agreement, the Company shall prepare and file with the SEC a
proxy statement relating to the Company's Stockholders' Meeting (together with
any amendments thereof or supplements thereto, the "PROXY STATEMENT"). Parent
shall furnish all information concerning itself to the Company as the Company
may reasonably request in connection with such actions and the preparation of
the Proxy Statement. As soon as reasonably practicable after clearance from the
SEC, the Company shall mail the Proxy Statement to its stockholders. The Proxy
Statement shall not be filed, and no amendment or supplement to the Proxy
Statement will be made by the Company, without prior consultation with Parent
and its counsel.

    (b) Parent agrees promptly to advise the Company if at any time prior to the
Company Stockholders' Meeting (as defined above) any information provided by it
in the Proxy Statement is or becomes incorrect or incomplete in any material
respect and to provide the Company with the information needed to correct such
inaccuracy or omission.

    SECTION 5.2  ACCESS TO INFORMATION; CONFIDENTIALITY.  The Company shall, and
shall cause its subsidiaries to, afford Parent, and the officers, employees,
accountants, counsel, financial advisors and other representatives of Parent,
reasonable access during normal business hours during the period prior to the
Effective Time to all their respective properties, books, contracts,
commitments, personnel and records and, during such period, the Company shall,
and shall cause each of its subsidiaries to, furnish promptly to Parent, (a) a
copy of each report, schedule, registration statement and other document filed
by it during such period pursuant to the requirements of federal or state
securities laws and (b) all other information concerning its business,
properties and personnel as Parent may reasonably request. Except as required by
law, each of the Company and Parent will hold, and will cause its respective
officers, employees, accountants, counsel, financial advisers and other
representatives and affiliates to hold, any confidential information in
accordance with the Confidentiality Agreement.

    SECTION 5.3  REASONABLE EFFORTS; NOTIFICATION.

    (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the Company, Parent and Sub agrees to use commercially
reasonable efforts to take, or cause to be taken, all actions, and to do, or
cause to be done, and to assist and cooperate with the other parties in doing,
all things necessary, proper or advisable to consummate and make effective, in
the most expeditious manner practicable, the Merger and the other transactions
contemplated by this Agreement, including (i) the making of all necessary
applications, registrations and filings (including filings with Governmental
Entities, if any), (ii) the obtaining of all necessary actions or nonactions,
licenses, consents, approvals or waivers from Governmental Entities and other
third parties and (iii) taking of all reasonable steps as may be necessary to
obtain an approval or waiver from, or to avoid an action or proceeding by, any
Governmental Entity, (iv) the execution and delivery of any additional
instruments necessary to consummate the transactions contemplated by, and to
fully carry out the purposes of, this Agreement, (v) the defending of any
lawsuits or other legal proceedings, judicial or administrative, challenging
this Agreement or the consummation of the transactions contemplated hereby or
thereby, including the using of all commercially reasonable efforts necessary to
lift, rescind or mitigate the effect of any injunction or restraining order or
other order adversely affecting the ability of any party hereto to consummate
the transactions contemplated hereby, (vi) the using of all commercially
reasonable efforts to fulfill all conditions to the obligations of Parent
(including obtaining any financing necessary to consummate the Merger), Sub or
the Company pursuant to this Agreement, and (vii) the using of all commercially
reasonable efforts to prevent, with respect to a threatened or pending
temporary, preliminary or permanent injunction or other order, decree or ruling
or statute, rule, regulation or executive order, the entry, enactment or
promulgation thereof, as the case may be; provided, however, that Parent shall
not be obligated to take any action pursuant to the foregoing if the taking of
such action or the obtaining of any waiver, license, consent, approval or
exemption is reasonably likely to be materially burdensome to Parent and its
subsidiaries taken as a whole or to impact in a materially adverse manner the
economic or business benefits of the transactions contemplated by this Agreement
so as to render inadvisable the consummation of the Merger.

    (b) The Company shall give prompt written notice to Parent, and Parent shall
give prompt written notice to the Company, of (i) any representation or warranty
made by it contained in this Agreement that is qualified as to materiality
becoming untrue or inaccurate in any respect or any such representation or
warranty that is not so qualified becoming untrue or inaccurate in any material
respect, (ii) the failure by it to comply with or satisfy in any material
respect any covenant, condition or agreement to be complied with or satisfied by
it under this Agreement or (iii) the occurrence of any change or event having,
or which insofar as can reasonably be foreseen to have, a Material Adverse
Effect on the Company; provided, however, that no such notification shall (A)
affect the representations, warranties, covenants or agreements of the parties
or the conditions to the obligations of the parties under this Agreement or (B)
limit or otherwise affect the remedies available hereunder to the party
receiving such notice.

    SECTION 5.4  GAMING APPROVALS.

    (a) GAMING APPROVALS.

        (i) Upon the terms and subject to the conditions set forth in this
    Agreement, each of the Company and Parent agrees 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, qualifications, consents,
    waivers, variances, exemptions, orders, approvals and authorizations of all
    Governmental Entities which are necessary in connection with the
    consummation of the transactions contemplated by this Agreement (whether
    required to be made or obtained prior to or after the Effective Time) (all
    of the foregoing, collectively "GAMING APPROVALS") and to comply with the
    terms and conditions of all such Gaming Approvals. Each of the Company and
    Parent shall use all commercially reasonable efforts to, and to cause their
    respective officers, directors and affiliates to, file within thirty days
    after the date hereof, and in all events shall file within sixty days after
    the date hereof, all required initial applications and documents in
    connection with obtaining the Gaming Approvals and shall act reasonably and
    promptly thereafter in responding to additional requests in connection
    therewith. Parent and the Company shall have the right to review in advance,
    and to the extent practicable, each will consult with the other on, in each
    case subject to applicable laws relating to the exchange of information, all
    the information relating to the Company or Parent 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
    Governmental Entity in connection with the transactions contemplated by this
    Agreement. The Company and Parent agree to promptly advise each other upon
    receiving any communication from any Governmental Entity which causes such
    party to believe that there is a reasonable likelihood that any Gaming
    Approval required from such Governmental Entity will not be obtained or that
    the receipt of any such approval will be materially delayed.

        (ii) Promptly following the execution of this Agreement, the Company
    shall use its commercially reasonable efforts to cause the sale of the
    Riverboat Complex for cash in a stock or asset sale transaction (including a
    transaction where the riverboat is first contributed to GSMC and the stock
    of GSMC is sold), such disposition to (i) include the termination of, or the
    assignment and assumption by the purchaser of the Riverboat Complex of, any
    leases (including, without limitation, leases relating to furniture,
    fixtures and equipment used thereon) or any guaranties thereof or other
    agreements relating to the Riverboat Complex or its operation, (ii) be
    effected for a price (including but not limited to provisions relating to
    the allocation of the purchase price among the assets sold) satisfactory to
    Parent and (iii) be made in a manner, to the extent possible, that is, after
    consultation with Parent, tax efficient. Notwithstanding the foregoing, if
    the Company presents to Parent a proposed sale of the Riverboat Complex,
    Parent shall, within five business days thereof, either (i) subject to
    Parent having obtained, or representing to the Company that it has been
    advised by the applicable Governmental Entity that it is likely to receive
    within thirty (30) days or less, all Gaming Approvals required to acquire
    the Riverboat Complex, give notice to the Company that it is withholding its
    approval of such sale and in such event the condition specified in Section
    6.2(f) hereof and Parent's right to approve the price shall be deemed waived
    by Parent, or (ii) give notice to the Company that it either approves of the
    proposed sale or approves of the proposed sale subject to the receipt of an
    opinion of an investment banking firm designated by Parent and approved by
    the Company, such approval not to be unreasonably withheld, that the
    consideration received for the Riverboat Complex is fair to the Company from
    a financial point of view, such opinion to be given without taking into
    consideration the existence of this Agreement or the proposed Merger (the
    "FAIRNESS OPINION"). In the event that Parent approves of the sale subject
    to the receipt of a Fairness Opinion and such opinion cannot for any reason
    be obtained, then the Company shall not proceed with the sale and the
    condition specified

                                      A-25
<PAGE>
    in Section 6.2(f) hereof and Parent's right to approve the price shall
    remain effective. In all events, Parent shall have the right to review and
    approve the terms of the sale other than the price received, such approval
    not to be unreasonably withheld. The Company shall, as part of its efforts
    to sell the Riverboat Complex, consult with Parent regarding its sales
    efforts and shall use commercially reasonable efforts to obtain the best
    terms for the sale of the Riverboat Complex. If requested by Parent, the
    Company shall use its commercially reasonable efforts to assist Parent in
    obtaining all Gaming Approvals necessary to permit Parent to acquire the
    Riverboat Complex as part of the Merger (it being understood that any
    conditions that may be imposed by regulatory authorities must be acceptable
    to Parent).

        (iii) The Company shall use its commercially reasonable efforts to sell
    or terminate (by means of withdrawal or otherwise) all of the Company's
    direct or indirect interests under that certain Amended and Restated Joint
    Venture Agreement of QNOV, dated July 31, 1998, by and among Shreveport
    Paddlewheels, LLC ("SPL"), Sodak LA and HWCC-Louisiana, Inc. ("HOLLYWOOD");
    that certain Amended and Restated Assignment of Joint Venture Interest,
    dated September 22, 1998, by and among Sodak LA and Hollywood, as Assignees
    and SPL and New Orleans Paddlewheels Inc. ("NOP"), as assignors; that
    certain Amended and Restated Master Agreement, dated July 31, 1998, by and
    among NOP, SPL, Hollywood and Sodak LA; that certain Consulting Agreement,
    dated July 31, 1998, by and between the Queen of New Orleans at the Hilton
    Joint Venture ("QNOV") and the Company; that certain Loan and Settlement
    Agreement, dated January 16, 1998, by and among NOP, SPL, Hollywood, Sodak
    LA and Hilton New Orleans Corporation ("HNOC"); that certain Indemnity
    Agreement, dated January 16, 1998 by and among NOP, HNOC, Sodak LA, SPL and
    Hollywood; that certain Loan and Settlement Agreement, dated January 16,
    1998, by and among NOP, Hollywood, Sodak LA, SPL and HNOC; that certain
    Compromise Agreement, dated January 16, 1998, by and among HNOC, NOP, QNOV
    and the City of New Orleans; that certain Side Agreement, dated January 16,
    1998, by and among QNOV, Hollywood and Sodak LA; that certain Indemnity
    Agreement--Physical Inspections, by and among NOP, SPL, Sodak LA, Hollywood
    and Red River Entertainment of Shreveport Partnership in Commendam; those
    certain Loan Agreement, Security Agreement, Guaranty Agreement and Marine
    Services Agreement contemplated to be entered into by and among SPL,
    Hollywood and Sodak LA (collectively, the "LOUISIANA JOINT VENTURE
    AGREEMENTS") (either directly and/or through the sale of all of the
    Company's interests in Sodak LA) pursuant to documentation in form and
    substance (other than as to price) reasonably satisfactory to Parent;
    PROVIDED that the minimum price shall be an amount equal to all loans,
    advances and additional capital contributions to, or investments in, Sodak
    LA, the Joint Venture or any Joint Venture partner made with the consent of
    Parent after the date hereof (it being understood that $2.5 million has been
    contributed by the Company as of the date hereof). The Company shall not
    provide any consideration in connection with such sale or termination other
    than a forfeiture of the $2.5 million capital contribution made by the
    Company as of the date hereof. Upon the consummation of such sale, neither
    the Company nor any of its subsidiaries shall have any further liabilities
    or obligations of any nature whatsoever relating to the Louisiana Joint
    Venture Agreements or the sale or termination thereof. The Company shall, as
    part of its efforts to sell its interests in the Louisiana Joint Venture
    Agreements, consult with the Parent regarding its sales efforts and shall
    use commercially reasonable efforts to obtain the best terms for the sale of
    its interests in the Louisiana Joint Venture Agreements.

        Parent shall have the right, at any time during the period commencing on
    the date 90 days after the date of this Agreement and ending on the date 180
    days after the date of this Agreement, if the Company has not prior thereto
    entered into a definitive agreement with a third party purchaser to sell its
    interests in the Louisiana Joint Venture Agreements in accordance with the
    preceding paragraph, to require Thomas Celani and Roland W. Gentner, or an
    entity wholly owned by them, to purchase all of the Company's interests
    under the Louisiana Joint Venture Agreements (either directly and/or through
    the purchase of all the Company's interests in Sodak

                                      A-26
<PAGE>
    LA) and as consideration therefor Thomas Celani and Roland W. Gentner shall
    assume all of the Company's obligations under the Louisiana Joint Venture
    Agreements and, in addition, pay to Parent the consideration specified in
    that certain letter to Thomas Celani and Roland W. Gentner dated as of the
    date hereof; provided that such consideration shall be increased by an
    amount equal to all loans, advances and additional capital contributions to,
    or investments in, Sodak LA, the Joint Venture or any Joint Venture partner
    made with the consent of Parent after the date hereof (it being understood
    that $2.5 million has been contributed by the Company as of the date
    hereof). Thomas Celani and Roland W. Gentner agree to promptly prepare and
    file all necessary documentation, to effect all applications, notices,
    petitions and filings, and to use best efforts to obtain as promptly as
    practicable all Gaming Approvals necessary for Thomas Celani and Roland W.
    Gentner to effect such transaction. The documentation to effect such
    transaction shall be prepared by Parent, shall not contain any
    representations or warranties by the Company other than with respect to the
    Company's ownership of the interests being purchased and shall not provide
    for any continuing obligations on the part of the Company or any of its
    subsidiaries in connection with such purchase or with respect to the
    Louisiana Joint Venture Agreements. Upon the request of Parent, the Company
    shall promptly undertake any actions required under the Louisiana Joint
    Venture Agreements in connection with such sale.

        (iv) Nothing in this Agreement, including but not limited to the
    provisions of Section 5.4(a)(ii) hereof, shall obligate Parent to take any
    action which may require or result in the voluntary surrender, forfeiture or
    other termination by Parent of, or otherwise have any material adverse
    impact on, any permits, registrations, licenses, findings of suitability,
    qualifications, consents, waivers, variances, exemptions, orders, approvals
    and authorizations of all Governmental Entities which are then held by
    Parent or any of its subsidiaries.

    (b) DENIAL OF LICENSE; INDIVIDUALS. If any person shall become an Ineligible
Person prior to the Closing, then (i) each Ineligible Person shall, and the
Company shall cause each Ineligible Person to, immediately and permanently,
resign from any position, including as director or officer, in the Company,
Parent or Sub and each Ineligible Person shall have no further management role
in Parent, Sub or the Company, (ii) if required to do so by any Governmental
Entity as a condition to receipt of any Gaming Approval, each Ineligible Person
shall, and the Company shall cause each Ineligible Person to, dispose of all of
its securities or other ownership interests in the Company, and (iii) each
Ineligible Person shall, and the Company shall cause each Ineligible Person to,
cooperate with the Company, Parent and Sub in their efforts to obtain and retain
in full force and effect the Gaming Approval. "INELIGIBLE PERSON" shall mean any
person who owns any capital stock or other interest in the Company (i) who is
denied a Gaming Approval, disqualified from eligibility for a Gaming Approval or
found unsuitable by any Governmental Entity before the Closing Date, (ii) whose
continued involvement in the business of the Company as an employee, director,
officer or otherwise, may, in Parent's reasonable opinion after consultation
with counsel, have a Material Adverse Effect on the likelihood that any
Governmental Entity will issue a Gaming Approval to the Company, the Surviving
Corporation, Sub or Parent or (iii) is expressly precluded from having any
continuing interest in the Company, the Surviving Corporation, Sub or Parent in
any Gaming Approval granted by a Governmental Entity as a condition to the
issuance or continued validity of any Gaming Approval by any Governmental
Entity.

    SECTION 5.5  STOCK OPTIONS; EMPLOYEE BENEFITS.

    (a) STOCK OPTION PLANS.

        (i) Any Stock Option outstanding immediately prior to the Effective Time
    which is then exercisable or becomes exercisable as a result of an
    acceleration triggered by the Merger pursuant to any existing option
    agreements and all Stock Options outstanding immediately prior to the
    Effective Time that were granted to members of the Board of Directors of the
    Company pursuant to the 1993 Directors' Stock Option Plan (all such Stock
    Options being the "VESTED OPTIONS"),

                                      A-27
<PAGE>
    shall be cancelled and, subject to the Company's receipt of the
    acknowledgement described in Section 6.2(i) from the holder of such Vested
    Options, shall entitle the holder thereof, upon surrender thereof, to
    receive, for each share of Company Common Stock subject to such Vested
    Option, an amount (subject to any applicable withholding tax) in cash equal
    to the Merger Consideration minus the per share exercise or purchase price
    of such Vested Option as of the date hereof.

        (ii) Any restricted shares of Company Common Stock granted to any
    employee of the Company outstanding immediately prior to the Effective Time
    ("RESTRICTED SHARES"), whether or not then vested and transferable by such
    employee, shall be converted, by virtue of the Merger and without any action
    on the part of the holder thereof, into the right to receive, without
    interest, the Merger Consideration.

        (iii) Amounts contributed to the Company's Employee Stock Purchase Plan
    (the "STOCK PURCHASE PLAN") for the purchase of Company Common Stock that,
    prior to the Effective Time, have not yet been applied to the purchase of
    Company Common Stock shall be applied to the purchase of Company Common
    Stock immediately prior to the Effective Time at a purchase price per share
    equal to the purchase price that would have been paid pursuant to the terms
    of the Stock Purchase Plan had the date on which the Effective Time occurs
    been the last day of an investment cycle under the Stock Purchase Plan. Each
    share of Company Common Stock purchased pursuant to this Section 5.5(a)(iii)
    shall be converted into the Merger Consideration in accordance with Section
    2.1(c)(i) of this Agreement. The Company will amend the Stock Purchase Plan
    to provide that no contributions can be made to the Stock Purchase Plan
    after a date that is no later than the last day of the Company's regular
    payroll period ending immediately prior to the Effective Time, and no such
    contributions shall actually be made.

    (b) EMPLOYEE BENEFITS. From and after the Effective Time, Parent shall, or
cause the Surviving Corporation to, provide all of the employees of the
Surviving Corporation and its subsidiaries with all employee benefit plans,
programs, policies or arrangements (the "PARENT BENEFIT PLANS") as are provided
by Parent and its subsidiaries to their own employees who are similarly
situated. From and after the Effective Time, if any director, officer or other
employee of the Company or its subsidiaries becomes eligible to participate in
any compensation or benefit plan, agreement or arrangement maintained by Parent,
the Surviving Corporation or any of their respective subsidiaries, Parent shall
cause (i) all service of such director, officer or employee completed prior to
the Effective Time with Company or any of its subsidiaries to be recognized
under such plan, agreement or arrangement for all purposes except, in the case
of a defined benefit retirement plan, for benefit accrual purposes, (ii) to be
waived any waiting or eligibility periods or exclusions for pre-existing
conditions (except that the waiver of the exclusions for pre-existing conditions
shall not require coverage of any condition which would not have been covered
under Parent's medical benefit plans had the condition not been pre-existing)
of, any such director, officer or employee and his or her dependents and (iii)
to be recognized all co-payments, deductibles or similar amounts or costs
incurred by any such director, officer or employee under a comparable plan,
agreement or arrangement of the Company or any of its subsidiaries during the
plan year in which such director, officer or employee commences participation in
an applicable benefit plan, agreement or arrangement of Parent, the Surviving
Corporation or any of their respective subsidiaries. The foregoing shall not
constitute any commitment, contract, understanding or undertaking, guarantee
(express or implied) on the part of the Surviving Corporation to continue the
employment of any employee of the Company for any term of duration or on any
terms other than those as the Surviving Corporation may establish.

    (c) CONTINUATION OF AGREEMENTS. The Surviving Corporation and its

"moratorium," "control share," "business combination," "shareholder protection"
or similar or other anti-takeover statute or regulation enacted under any state
or Federal law shall become applicable to the Merger or any of the other
transactions contemplated hereby, the Company and the Board of Directors of the
Company shall grant such approvals and take all such actions as are within its
authority so that the Merger and the other transactions contemplated hereby and
thereby may be consummated as promptly as practicable on the terms contemplated
hereby and thereby and otherwise use all commercially reasonable efforts to
eliminate the effects of such statute or regulation on the Merger and the
transactions contemplated hereby and thereby. The Company has not and, during
the term of this Agreement shall not, adopt, effect or implement any
"shareholders' rights plan," "poison pill" or similar arrangement.

    SECTION 5.7  INDEMNIFICATION, EXCULPATION AND INSURANCE.

    (a) The articles of incorporation and the by-laws of the Surviving
Corporation shall contain the provisions with respect to indemnification and
exculpation from liability set forth in the Company's articles of incorporation
and by-laws on the date of this Agreement, which provisions shall not be
amended, repealed or otherwise modified for a period of six years from the
Effective Time in any manner that would adversely affect the rights thereunder
of individuals who on or prior to the Effective Time were directors, officers,
employees or agents of the Company, unless such modification is required by law.

    (b) For six years from the Effective Time, Parent shall maintain in effect
directors' and officers' liability insurance covering those persons who are
currently covered by the Company's directors' and officers' liability insurance
policy (a copy of which has been heretofore made available to Parent) on terms
no less favorable to such indemnified parties than the terms of such current
insurance coverage; PROVIDED, HOWEVER, that (i) in lieu of the purchase of such
insurance by the Surviving Corporation or Parent, the Company, with Parent's
written consent, may purchase a five-year extended reporting period endorsement
("reporting tail coverage") under its existing directors' and officers'
liability insurance coverage and (ii) if the cost of such insurance in any year
during such six-year period shall exceed 150% of the premium cost for such
policy for the year ended June 30, 1999 (such premium being the "CURRENT
PREMIUM"), then Parent shall cause the Surviving Corporation to, and the
Surviving Corporation shall, provide coverage affording the same protection as
maintained by Parent as of such date for its officers and directors. The Company
represents to Parent that the Current Premium is $270,500.

    (c) In addition to the other rights provided for in this Section 5.7 and not
in limitation thereof, for six years from and after the Effective Time, Parent
and the Surviving Corporation shall, to the fullest extent permitted by
applicable law, (i) indemnify and hold harmless the individuals who on or prior
to the Effective Time were officers or directors of the Company (collectively,
the "INDEMNITEES") against all losses, Expenses (as hereinafter defined),
claims, damages, liabilities, judgments, or amounts paid in settlement
(collectively, "COSTS") in respect to any claim, action, suit or proceeding,
whether criminal, civil, administrative or investigative based on, or arising
out of or relating to the fact that such person is or was a director or officer
of the Company and arising out of acts or omissions occurring on or after July
1, 1998 and on or prior to the Effective Time (including, without limitation, in
respect of acts or omissions in connection with this Agreement and the
transactions contemplated hereby) to the fullest extent that the Company would
have been permitted under the SDBCA and its articles of incorporation and
by-laws in effect on the date hereof to indemnify such person (an "INDEMNIFIABLE
CLAIM") and (ii) advance to such Indemnitees all Expenses incurred in connection
with any Indemnifiable Claim promptly after receipt of reasonably detailed
statements therefor; PROVIDED, that

                                      A-29
<PAGE>
the person to whom Expenses are to be advanced provides an undertaking to repay
such advances if it is ultimately determined that such person is not entitled to
indemnification from the Surviving Corporation. In the event any Indemnifiable
Claim is asserted or made within such six year period, all rights to
indemnification and advancement of Expenses in respect of any such Indemnifiable
Claim shall continue until such Indemnifiable Claim is disposed of or all
judgments, orders, decrees or other rulings in connection with such
Indemnifiable Claim are fully satisfied. For the purposes of this Section 5.7,
"EXPENSES" shall include reasonable attorneys' fees and all other costs, charges
and expenses paid or incurred in connection with investigating, defending, being
a witness in or participating in (including on appeal), or preparing to defend,
be a witness in or participate in any Indemnifiable Claim.

    (d) Any Indemnitee wishing to claim indemnification under paragraph (c) of
this Section 5.7, upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify the Surviving Corporation thereof, but the
failure to so notify shall not relieve the Surviving Corporation of any
liability it may have to such Indemnitee if such failure does not materially
prejudice the indemnifying party. In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the Effective
Time), (i) the Surviving Corporation shall have the right to assume the defense
thereof and the Surviving Corporation shall not be liable to such Indemnitees
for any legal expenses of other counsel or any other expenses subsequently
incurred by such Indemnitees in connection with the defense thereof, except that
if the Surviving Corporation does not elect to assume such defense or counsel
for the Indemnitees advises that there are issues which raise conflicts of
interest between the Surviving Corporation and any Indemnitees or between any
two or more Indemnitees, such Indemnitees may retain counsel satisfactory to
them, and the Surviving Corporation shall pay all reasonable fees and expenses
of such counsel for the Indemnitees promptly as statements therefor are
received; PROVIDED, HOWEVER, that the Surviving Corporation shall be obligated
pursuant to this paragraph (d) to pay for only one firm of counsel for all
Indemnitees in any jurisdiction (unless there is a conflict of interest as
provided above), (ii) the Indemnitees will cooperate in the defense of any such
matter and (iii) the Surviving Corporation shall not be liable for any
settlement effected without the prior written consent of the Surviving
Corporation, which consent shall not be unreasonably withheld.

    (e) The obligations of the Company, the Surviving Corporation and Parent
contained in this Section 5.7 shall be binding on the successors and assigns of
Parent and the Surviving Corporation. If Parent, the Surviving Corporation or
any of their successors or assigns (i) consolidates with or merges into any
other person and shall not be the continuing or surviving corporation or entity
of such consolidation or merger or (ii) transfers all or substantially all of
its properties and assets to any person, then and in each such case, proper
provisions shall be made so that the successors and assigns of Parent or the
Surviving Corporation, as the case may be, shall assume the obligations set
forth in this Section 5.7.

    SECTION 5.8  LETTERS OF ACCOUNTANTS.  The Company shall use its commercially
reasonable efforts to cause to be delivered to Parent a "comfort" letter of KPMG
Peat Marwick LLP, the Company's independent public accountants, dated and
delivered on the date on which the Proxy Statement is mailed to stockholders of
the Company and dated the Closing Date, each addressed to Parent, in form and
substance reasonably satisfactory to Parent and reasonably customary in scope
and substance for letters delivered by independent public accountants in
connection with transactions such as those contemplated by this Agreement.

    SECTION 5.9  FEES AND EXPENSES.  Except as provided in Section 7.5, whether
or not the Merger is consummated, all costs and expenses incurred in connection
with this Agreement and the transactions contemplated hereby shall be paid by
the party incurring such expenses; PROVIDED, HOWEVER, that those expenses
incurred in connection with printing and mailing the Proxy Statement, including
the filing fee paid to the SEC, and all filing fees related to compliance with
the HSR Act in connection with the transactions contemplated hereby shall be
shared equally by Parent and the Company.

SALOMON SMITH BARNEY

           A member of Citigroup

March 10, 1999

Board of Directors
Sodak Gaming, Inc.
5301 S. Highway 16
Rapid City, SD 57701

Members of the Board:

    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of common stock, par value $.001 per share ("Company Common
Stock"), of Sodak Gaming, Inc. (the "Company"), of the consideration to be
received by such holders in connection with the proposed merger (the "Merger")
of SAC, Inc. ("Sub"), a wholly owned subsidiary of International Game Technology
("Parent"), with and into the Company, pursuant to an Agreement and Plan of
Merger, dated as of March 10, 1999 (the "Merger Agreement"), among Parent, Sub
and the Company. Upon the effectiveness of the Merger, each issued and
outstanding share of Company Common Stock (other than shares of Company Common
Stock (a) owned by the Company or any subsidiary of the Company, or Parent, Sub
or any other subsidiary of Parent or (b) held by stockholders who duly exercise
appraisal rights) will be converted into the right to receive $10.00 in cash
(the "Merger Consideration").

    In connection with rendering our opinion, we have reviewed certain publicly
available information concerning the Company and certain other financial
information concerning the Company, including financial forecasts, that were
provided to us by the Company. We have discussed the past and current business
operations, financial condition and prospects of the Company with certain
officers and employees of the Company. We have also considered such other
information, financial studies, analyses, investigations and financial, economic
and market criteria that we deemed relevant.

    In our review and analysis and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of the information reviewed by us
for the purpose of this opinion and we have not assumed any responsibility for
independent verification of such information. Without limiting the generality of
the foregoing, we have relied upon the accuracy of information provided to us by
the Company relating to the rights of Parent under specified circumstances to
terminate certain material contracts between the Company and Parent. With
respect to the financial forecasts of the Company, we have been advised by the
management of the Company that such forecasts have been reasonably prepared on
bases reflecting its best currently available estimates and judgments, and we
express no opinion with respect to such forecasts or the assumptions on which
they are based. We have not assumed any responsibility for any independent
evaluation or appraisal of any of the assets (including properties and
facilities) or liabilities of the Company. We were not asked to, and did not,
solicit other proposals to acquire the Company.

    Our opinion is necessarily based upon conditions as they exist and can be
evaluated on the date hereof. Our opinion does not address the Company's
underlying business decision to effect the Merger,

                                      B-1
<PAGE>
and we express no view on the effect on the Company of the Merger and related
transactions. Our opinion is directed only to the fairness, from a financial
point of view, of the Merger Consideration to holders of Company Common Stock
and does not constitute a recommendation concerning how holders of Company
Common Stock should vote with respect to the Merger Agreement or the Merger.

    We have acted as financial advisor to the Board of Directors of the Company
in connection with the Merger and will receive a fee for our services, all of
which is contingent upon consummation of the Merger. In the ordinary course of
business, we and our affiliates may actively trade the securities of the Company
and Parent 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.
In addition, we and our affiliates have previously rendered certain investment
banking and financial advisory services to the Company and Parent for which we
have received customary compensation. We and our affiliates (including Citigroup
Inc.) may have other business relationships with the Company or Parent in the
ordinary course of their businesses.

    Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Merger Consideration is fair to the holders of Company Common
Stock from a financial point of view.

                                          Very truly yours,

                                          SALOMON SMITH BARNEY INC.

                 FORM OF IRREVOCABLE PROXY AND VOTING AGREEMENT

March 10, 1999

International Game Technology

Reno, Nevada 89511
Attn: Brian McKay

Re:  Agreement of Significant Stockholders Concerning Transfer and Voting of
     Shares of Sodak Gaming, Inc.

    I understand that you and Sodak Gaming, Inc. (the "Company"), of which the
undersigned is a significant stockholder, are prepared to enter into an
agreement for the merger of the Company with and into a wholly-owned subsidiary
("Sub") of Parent, but that you have conditioned your willingness to proceed
with such agreement (the "Agreement") upon your receipt from me of assurances
satisfactory to you of my support of and commitment to the Merger. I am familiar
with the Agreement and the terms and conditions of the Merger, as approved by
the board of directors of the Company. Terms used but not otherwise defined
herein shall have the same meanings as are given them in the Agreement. In order
to evidence such commitment and to induce you to enter into the Agreement, I
hereby represent and warrant to you and agree with you as follows:

    1. VOTING. I will vote or cause to be voted all shares of capital stock of
the Company owned of record or beneficially owned or held in any capacity by me
or under my control, by proxy or otherwise, in favor of the Merger and other
transactions provided for in or contemplated by the Agreement and against any
inconsistent proposals or transactions. I hereby revoke any other proxy granted
by me and irrevocably appoint you, during the term of this letter agreement, as
proxy for and on behalf of me to vote (including, without limitation, the taking
of action by written consent) such shares, for me and in my name, place and
stead for the matters and in the manner contemplated by this Section 1. This
proxy is irrevocable.

    2. OWNERSHIP. As of the date hereof, my only ownership of, or interest in,
equity securities of the Company, including proxies granted to me, consists
solely of the interests described in Schedule 1 attached hereto (collectively,
the "Shares").

    3. RESTRICTION ON TRANSFER. I will not sell, transfer, pledge or otherwise
dispose of any of the Shares or any interest therein (including the granting of
a proxy to any person) or agree to sell, transfer, pledge or otherwise dispose
of any of the Shares or any interest therein prior to the Merger, without your
express written consent. Any transferee of the Shares must, as a condition to
receipt of such Shares, agree to bound by the terms hereof.

    4. SHARE LEGEND. At your request, the following legend shall be placed on
the certificates for the Shares:

       THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND
       CONDITIONS OF A VOTING AGREEMENT DATED MARCH 10, 1999 BETWEEN THE
       REGISTERED HOLDER HEREOF AND INTERNATIONAL GAME TECHNOLOGY, A COPY OF
       WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF INTERNATIONAL GAME
       TECHNOLOGY.

    5. NO SOLICITATION. From the date hereof until the termination hereof, I
will not, directly or indirectly, (i) take any action to solicit, initiate or
encourage any Takeover Proposal or (ii) engage in

                                      C-1
<PAGE>
negotiations or discussions with, or disclose any nonpublic information relating
to the Company or any subsidiary of the Company to, or otherwise assist,
facilitate or encourage, any person (other than Parent and Sub) that may be
considering making, or has made, a Takeover Proposal. I will notify Sub within
24 hours after receipt by me of any Takeover Proposal or any indication that any
such third party is considering making a Takeover Proposal or any request for
nonpublic information relating to the Company or any subsidiary of the Company
or for access to the properties, books or records of the Company or any such
subsidiary by any such third party that may be considering making, or has made,
a Takeover Proposal. The foregoing provisions of this Section 5 shall not be
construed to limit actions taken, or to require actions to be taken, by me that
are required or restricted by my fiduciary duties or my employment duties, or
permitted by the Agreement, and that, in each case, are undertaken solely in my
capacity as a director or officer of the Company.

    6. ACKNOWLEDGEMENT; WAIVER OF CLAIMS. The undersigned acknowledges that you
requested the undersigned and three other stockholders of the Company to provide
the agreements contained in this letter agreement and to agree, if required by
you, and subject to the receipt of all necessary Gaming Approvals, to purchase
the Company's interest in, and to assume the Company's obligations under, the
Louisiana Joint Venture Agreements in accordance with Section 5.4(a)(iii) of the
Agreement. The undersigned hereby declines to grant to you the right to require
the undersigned to purchase the Company's interest in, and to assume the
Company's obligations under, the Louisiana Joint Venture Agreements in
accordance with Section 5.4(a)(iii) of the Agreement. The undersigned shall have
no claims, and expressly waives any claim, direct or indirect, derivative or
other, against you, the Company or any such other stockholders arising out of,
related to or based upon the request for such assurances or agreement, the grant
or declination by any stockholder of such requests, any exercise of your rights
under such Section 5.4(a)(iii) and the transfer resulting therefrom or the
consummation of the transactions contemplated by the Agreement.

    7. EFFECTIVE DATE; SUCCESSION; REMEDIES; TERMINATION. Upon your acceptance
and execution of the Agreement, this letter agreement shall mutually bind and
benefit you and me, any of our heirs, successors and assigns and any of your
successors. You will not assign the benefit of this letter agreement other than
to a wholly owned subsidiary. I agree that in light of the inadequacy of damages
as a remedy, specific performance shall be available to you, in addition to any
other remedies you may have for the violation of this letter agreement. This
letter agreement (including the proxy granted herein) shall terminate on the
earlier of (i) termination of the Agreement and (ii) December 31, 1999, or such
later date, if any, to which Parent and the Company agree to extend the date
specified in Section 7.1(e) of the Agreement. The provisions of Section 6 shall
survive any such termination and shall be for the benefit of you, the Company
and the other stockholders referred to in Section 6.

    8. NATURE OF HOLDINGS; SHARES. All references herein to our holdings of the
Shares shall be deemed to include Shares held or controlled by the undersigned,

                     SOUTH DAKOTA BUSINESS CORPORATION ACT

    47-6-23 DISSENT BY SHAREHOLDER FROM MERGER, CONSOLIDATION, OR TRANSFER
PLAN.--Any shareholder of a domestic corporation shall have the right to dissent
from, and to obtain payment for his shares in the event of, any of the following
corporate actions:

    (1) Any plan of merger or consolidation to which the corporation is a party;

    (2) Any sale or exchange of all or substantially all of the property and
assets of the corporation not made in the usual and regular course of its
business, including a sale in dissolution, but not including a sale pursuant to
an order of a court having jurisdiction in the premises or a sale for cash on
terms requiring that all or substantially all of the net proceeds of sale be
distributed to the shareholders in accordance with their respective interests
within one year after the date of sale;

    (3) Any plan of exchange to which the corporation is a party as the
corporation the shares of which are to be acquired;

    (4) Any amendment of the articles of incorporation which materially and
adversely affects the rights appurtenant to the shares of the dissenting
shareholder in that it:

    (a) Alters or abolishes a preferential right to such shares;

    (b) Creates, alters or abolishes a right in respect of the redemption of
such shares, including a provision respecting a sinking fund for the redemption
or repurchase of such shares;

    (c) Alters or abolishes a preemptive right of the holder of such shares to
acquire shares or other securities;

    (d) Excludes or limits the right of the holder of such shares to vote on any
matter, or to cumulate his votes, except as such right may be limited by
dilution through the issuance of shares or other securities with similar voting
rights; or

    (5) Any other corporate action taken pursuant to a shareholder vote with
respect to which the articles of incorporation, the bylaws, or a resolution of
the board of directors directs that dissenting shareholders shall have a right
to obtain payment for their shares.

    47-6-23.1 DISSENT AS TO LESS THAN ALL SHARES HELD--BENEFICIAL OWNER.--A
record holder of shares may assert dissenters' rights as to less than all of the
shares registered in his name only if he dissents with respect to all the shares
beneficially owned by any one person, and discloses the names and address of the
person or persons on whose behalf he dissents. In that event, his rights shall
be determined as if the shares as to which he has dissented and his other shares
were registered in the names of different shareholders.

    A beneficial owner of shares who is not the record holder may assert
dissenters' rights with respect to shares held on his behalf, and shall be
treated as a dissenting shareholder under the terms of this section if he
submits to the corporation at the time of or before the assertion of these
rights a written consent of the record holder.

    47-6-23.2 RIGHTS OF SHAREHOLDERS NOT ENTITLED TO VOTE ON MERGER.--The right
to obtain payment under section 34 of this Act does not apply to the
shareholders of the surviving corporation in a merger if a vote of the
shareholders of such corporation is not necessary to authorize such merger.

    47-6-23.3 SHAREHOLDER ENTITLED TO PAYMENT MAY NOT ATTACK VALIDITY OF
ACTION.--A shareholder of a corporation who has a right under Section47-6-23 to
obtain payment for his

                                      D-1
<PAGE>
shares may not, at law or in equity, attack the validity of the corporate action
that gives rise to his right to obtain payment, have the action set aside or
rescinded, unless the corporate action is unlawful or fraudulent with regard to
the complaining shareholder or to the corporation.

    47-6-40 DEFINITIONS.--Terms used in this Act mean:

    (1) "Dissenter," a shareholder or beneficial owner who is entitled to and
does assert dissenters' rights under this Act, and who has performed every act
required up to the time involved for the assertion of such rights;

    (2) "Corporation," the issuer of the shares held by the dissenter before the
corporate action, or the successor by merger or consolidation of that issuer;

    (3) "Fair value" of shares, their value immediately before the effectuation
of the corporate action to which the dissenter objects, excluding any
appreciation or depreciation in anticipation of such corporate action unless
such exclusion would be inequitable;

    (4) "Interest," interest from the effective date of the corporate action
until the date of payment, at the average rate currently paid by the corporation
on its principal bank loans, or, if none, at such rate as is fair and equitable
under all the circumstances.

    47-6-41 NOTICE TO SHAREHOLDERS OF RIGHT TO DISSENT AND OBTAIN PAYMENT.--If a
proposed corporate action which would give rise to dissenters' rights under this
Act is submitted to a vote at a meeting of shareholders, the notice of meeting
shall notify all shareholders that they have or may have a right to dissent and
obtain payment for their shares by complying with the terms of this Act, and
shall be accompanied by a copy of SectionSection47-6-23 to 47-6-23.3, inclusive,
and SectionSection47-6-40 to 47-6-50, inclusive.

    47-6-42 NOTICE OF INTENT TO DISSENT--REFRAIN FROM VOTING--EFFECT OF
FAILURE.--If the proposed corporate action is submitted to a vote at a meeting
of shareholders, any shareholder who wishes to dissent and obtain payment for
his shares shall file with the corporation, prior to the vote, a written notice
of intention to demand that he be paid fair compensation for his shares if the
proposed action is effectuated, and shall refrain from voting his shares in
approval of such action. A shareholder who fails in either respect acquires no
right to payment of his shares under this section or SectionSection47-6-23 to
47-6-23.3, inclusive.

    47-6-43 NOTICE OF PROCEDURE FOR DEMANDING PAYMENT AND DEPOSITING
CERTIFICATES.--If the proposed corporate action is approved by the required vote
at a meeting of shareholders, the corporation shall mail a further notice to all
shareholders who gave due notice of intention to demand payment and who
refrained from voting in favor of the proposed action. If the proposed corporate
action is to be taken without a vote of shareholders, the corporation shall send
to all shareholders who are entitled to dissent and demand payment for their
shares a notice of the adoption of the plan of corporate action. The notice
shall (1) state where and when a demand for payment shall be sent and
certificates of certificated shares shall be deposited in order to obtain
payment, (2) inform holders of uncertificated shares to what extent transfer of
shares will be restricted from the time that demand for payment is received, (3)
supply a form for demanding payment which includes a request for certification
of the date on which the shareholder, or the person on whose behalf the
shareholder dissents, acquired beneficial ownership of the shares, and (4) be
accompanied by a copy of SectionSection47-6-23 to 47-6-23.3, inclusive, and
SectionSection47-6-40 to 47-6-50, inclusive. The time set for the demand and
deposit shall be not less than thirty days from the mailing of the notice.

    47-6-44 FAILURE TO DEMAND PAYMENT OR DEPOSIT CERTIFICATES--WAIVER--
RESTRICTION ON TRANSFERS.--A shareholder who fails to demand payment, or fails,
in the case of certificated shares, to deposit certificates, as required by a
notice pursuant to Section47-6-43 has no right under this Act to receive payment
for his shares. If the shares are not represented by certificates, the

                                      D-2
<PAGE>
corporation may restrict their transfer from the time of receipt of demand for
payment until effectuation of the proposed corporate action, or the release of
restrictions under the terms of SectionSection47-6-45 and 47-6-46. The dissenter
shall retain all other rights of a shareholder until these rights are modified
by effectuation of the proposed corporate action.

    47-6-45 RETURN OF CERTIFICATES OR RELEASE OF RESTRICTIONS ON FAILURE TO
EFFECTUATE ACTION--NEW NOTICE.--Within sixty days after the date set for
demanding payment and depositing certificates, if the corporation has not
effectuated the proposed corporate action and remitted payment for shares
pursuant to this Act, it shall return any certificates that have been deposited,
and release uncertificated shares from any transfer restriction imposed by
reason of the demand for payment.

    If uncertificated shares have been released from transfer restrictions, and
deposited certificates have been returned, the corporation may at any later time
send a new notice conforming to the requirements of Section47-6-43 with like
effect.

    47-6-46 REMITTANCE OF PAYMENT TO DISSENTING SHAREHOLDERS--INFORMATION TO
ACCOMPANY REMITTANCE.--Immediately upon effectuation of the proposed corporate
action, or upon receipt of demand for payment if the corporate action has
already been effectuated, the corporation shall remit to dissenters who have
made demand and, if their shares are certificated, have deposited their
certificates the amount which the corporation estimates to be the fair value of
the shares, with interest if any has accrued. The remittance shall be
accompanied by:

    (1) The corporation's closing balance sheet and statement of income for a
fiscal year ending not more than sixteen months before the date of remittance,
together with the latest available interim financial statements;

    (2) A statement of the corporation's estimate of fair value of the shares;
and

    (3) A notice of the dissenter's right to demand supplemental payment,
accompanied by a copy of SectionSection47-6-23 to 47-6-23.3, inclusive, and
SectionSection47-6-40 to 47-6-50, inclusive.

    47-6-47 DEMAND FOR DEFICIENCY--FAILURE TO DEMAND AS WAIVER.--If the
corporation fails to remit as required by Section47-6-46 or if the dissenter
believes that the amount remitted is less than the fair value of his shares, or
that the interest is not correctly determined, he may send the corporation his
own estimate of the value of the shares or of the interest and demand payment of
the deficiency.

    If the dissenter does not file such an estimate within thirty days after the
corporation's mailing of its remittance, he shall be entitled to no more than
the amount remitted.

    47-6-48 PETITION FOR JUDICIAL DETERMINATION OF VALUE OF SHARES--PARTIES--
PROCEDURE--EFFECT OF FAILURE TO FILE.--Within sixty days after receiving a
demand for payment pursuant to Section47-6-47, if any such demands for payment
remain unsettled, the corporation shall file in an appropriate court a petition
requesting that the fair value of the shares and interest thereon be determined
by the court.

    An appropriate court shall be a court of competent jurisdiction in the
county of this state where the registered office of the corporation is located.
If, in the case of a merger or consolidation or exchange of shares, the
corporation is a foreign corporation without a registered office in this state
the petition shall be filed in the county where the registered office of the
domestic corporation was last located.

    All dissenters, wherever residing, whose demands have not been settled shall
be made parties to the proceeding as in an action against their shares. A copy
of the petition shall be served on each such

                                      D-3
<PAGE>
dissenter; if a dissenter is a nonresident, the copy may be served on him by
registered or certified mail or by publication as provided by law.

    The jurisdiction of the court shall be plenary and exclusive. The court may
appoint one or more persons as appraisers to receive evidence and recommend a
decision on the question of fair value. The appraisers shall have such power and
authority as shall be specified in the order of their appointment or in any
amendment thereof. The dissenters shall be entitled to discovery in the same
manner as parties in other civil suits.

    All dissenters who are made parties shall be entitled, after a hearing
without a jury, to judgment for the amount by which the fair value of their
shares is found to exceed the amount previously remitted with interest.

    If the corporation fails to file a petition as provided in this section,
each dissenter who made a demand and who has not already settled his claim
against the corporation shall be paid by the corporation the amount demanded by
him with interest, and may sue therefor in an appropriate court.

    47-6-49 ASSESSMENT OF COSTS AND EXPENSES OF ACTION.--The costs and expenses
of any proceeding under section 61 of this Act, including the reasonable
compensation and expenses of appraisers appointed by the court, shall be
determined by the court and assessed against the corporation, except that any
part of the costs and expenses may be apportioned and assessed as the court
considers equitable against all or some of the dissenters who are parties and
whose action in demanding supplemental payment the court finds to be arbitrary,
vexatious, or not in good faith.

    Fees and expenses of counsel and of experts for the respective parties may
be assessed as the court considers equitable against the corporation and in
favor of any or all dissenters if the corporation failed to comply substantially
with the requirements of this section, and may be assessed against either the
corporation or a dissenter in favor of any other party, if the court finds that
the party against whom the fees and expenses are assessed acted arbitrarily,
vexatiously, or not in good faith in respect to the rights provided by
SectionSection47-6-23 to 47-6-23.3, inclusive, and SectionSection47-6-40 to
47-6-50, inclusive.

    If the court finds that the services of counsel for any dissenter were of
substantial benefit to other dissenters similarly situated and should not be
assessed against the corporation it may award to these counsel reasonable fees
to be paid out of the amounts awarded to the dissenters who were benefited.

    47-6-50 VALUE OF SHARES NOT BENEFICIALLY OWNED BY DISSENTER ON DATE OF FIRST
ANNOUNCEMENT.--Notwithstanding SectionSection47-6-40 to 47-6-49, inclusive, the
corporation may elect to withhold the remittance required by Section47-6-46 from
any dissenter with respect to shares of which the dissenter or the person on
whose behalf the dissenter acts was not the beneficial owner on the date of the
first announcement to news media or to shareholders of the terms of the proposed
corporate action. With respect to such shares, the corporation shall, upon
effectuating the corporate action, state to each dissenter its estimate of the
fair value of the shares, state the rate of interest to be used, explaining the
basis thereof, and offer to pay the resulting amounts on receiving the
dissenter's agreement to accept them in full satisfaction.

    If the dissenter believes that the amount offered is less than the fair
value of the shares and interest determined according to this section, he may
within thirty days after the date of mailing of the corporation's offer, mail
the corporation his own estimate of fair value and interest, and demand their
payment. If the dissenter fails to do so, he shall be entitled to no more than
the corporation's offer.

    If the dissenter makes a demand as provided herein the provisions of
SectionSection47-6-48 and 47-6-49 shall apply to further proceedings on the
dissenter's demand.
