<PAGE>

                                                                           - 6 -

      following provisions:

      -     five-year term

      -     redemption upon expiry of term

      -     interest usual in the market

      -     payment of interest at regular intervals

      -     redemption is to effect the Parties' liability arising from the
            guarantees granted in equal parts

      -     The Bank cannot make a demand upon Buyer under its guarantee unless
            a similar demand in the same amount is simultaneously made upon the
            Sellers under their guarantee, and vice versa. Similarly, the Bank
            shall use equal efforts to pursue its remedies against both the
            Sellers or the Buyer under the guarantees provided by each of them.

      -     Under no circumstances shall either Sellers, on the one hand, or
            Buyer, on the other, be liable for more than Twenty-Five Million
            Euros (EUR 25,000,000) plus interest and costs, in the aggregate,
            with respect to the Bank Loan.

3.4   In the event one security provider pays under his security less than the
      other security provider, the Party which paid less shall reimburse the
      other one-half (1/2) of the difference between the amounts paid by each of
      them under their respective securities, with the effect that, after
      considering such reimbursement, each will have paid the same amount under
      its respective security of the Bank Loan.

3.5   If both parties agree, the Bank Loan may as well be divided into two
      independent bank loans each amounting to EUR 25,000,000.00. In such case
      the Buyer shall be responsible for providing collateral for one loan and
      the Seller shall be responsible for providing collateral for the other
      loan. With regard to the liability arising from such guarantees the
      Parties agree to internally place each other in a position in which they
      would be in case of a loan pursuant to Section 3.3 and Section 3.4.

3.6   If 90 days after recording of this Agreement neither a binding loan
      agreement between AI and a bank regarding a loan in the amount of EUR
      50,000,000.00 nor two loan agreements in the amount of EUR 25,000,000.00
      each do exist, the Buyer itself shall be obligated to obtain an
      irrevocable loan commitment of a bank in the amount of EUR 25,000,000.00
      in favour of AI. Such loan commitment may be subject to the payment
      condition that the Sellers also obtain an irrevocable loan commitment in
      the amount of

<PAGE>

                                                                           - 7 -

      EUR 25,000,000.00 in favour of AI.

3.7   If the Buyer does not provide such loan commitment within further 30 days
      the following shall apply: The Sellers may rescind from this Agreement and
      the KV. Further claims of the Sellers do not exist, in particular, the
      Buyer does not have to pay a break-up fee in accordance with Section 16.2
      of the KV.

3.8   If only the Buyer submits a loan commitment within the timeframe set this
      Agreement and the KV shall continue to be valid and no rights to
      rescission shall exist.

3.9   Any commitment fee, closing costs and other costs set by the Bank (i) in
      connection with the issuance of the Bank Loan(s), and (ii) in connection
      with the guarantees granted by the parties shall be borne by AI.

3.10  The Sellers shall procure that AI uses the proceeds of the Bank Loan to
      reduce its liability with respect to the cash-pool of Gauselmann AG. If,
      after full and final settlement of the obligations vis-a-vis the cash-pool
      of Gauselmann AG, proceeds of the Bank Loan remain unutilised, such
      remaining proceeds of the Bank Loan may be used by AI to reduce other
      ordinary course liabilities of AI.

      present member were the appointed alternate member (if not already so
      appointed) of the absent member(s). In case there is no Quorum at a
      meeting of the advisory board, a new meeting with the same agenda shall be
      convened by notice by registered mail to each member of the advisory board
      and by observing a period of at least two weeks, or a reasonable shorter
      period if need be. This meeting even without a Quorum shall be empowered
      to make decisions, provided this was set out in the letter convening such
      meeting.

SECTION 6 FUTURE MAJOR ACQUISITIONS BY THE NEW SHAREHOLDER

6.1   From the Transaction Date through and as long as Shareholders I and II
      hold 50% and New Shareholder equally (directly or indirectly) holds 50% in
      the Parent Companies the following shall apply: If the New Shareholder
      publicly announces a Major Acquisition, the New Shareholder shall notify
      Shareholders I and II thereof in writing (a "Major Acquisition Notice")
      promptly after such announcement. Shareholders I and II shall have the
      right, but not the obligation, to Participate in the Major Acquisition.

6.2   Shareholders I and II shall have sixty (60) days after the date the Major
      Acquisition Notice is received (the "Participation Election Period")
      during which to give notice to

                                                                          - 12 -

      New Shareholder indicating their decision to Participate in the Major
      Acquisition (a "Participation Election Notice"). Failure to give a
      Participation Election Notice prior to the expiration of the Participation
      Election Period shall be deemed an election on the part of Shareholders I
      and II not to Participate in the Major Acquisition.

6.3   In case Shareholders I and II decide to participate, they are jointly
      entitled to take over 50% of the participation to be acquired by New
      Shareholder under the same terms and conditions as apply for New
      Shareholder plus half of the transaction costs.

SECTION 7 DISPOSAL OF INTERESTS - GENERAL

      After the Transaction Date, each Shareholder of the Parent Companies or of
      the Silent Partnership may dispose of any of its Interest only subject to
      the provisions of this Agreement and the Organizational Documents and to
      all shares of all companies being concerned.

SECTION 8 PUT AND CALL RIGHTS

8.1   The following put options shall be agreed for Shareholders I and II
      (jointly) with regard to the shares/Interests in the Parent Companies and
      the Atypical Silent Partnership ("Option Interests"):

8.1.1 As of the Transaction Date Shareholders I and II may exercise a put option
      if they do not accept an offer in accordance with Section 6 of this
      Agreement. This put option may only be exercised within 60 days after a
      Notice of a Major Acquisition has been issued. The consummation of the
      Major Acquisition is a condition precedent for the consummation of this
      option. The right to consummate an exercised option ceases to exist if
      such Major Acquisition did not take place within 18 months after the
      Notice of a Major Acquisition. The right to exercise such option expires
      on the fifth anniversary of the Transaction Date.

8.1.2 Upon expiry of two years after the Transaction Date and until the fifth
      anniversary of the Transaction Date Shareholders I and II may exercise a
      put option, if disagreement as described below exists ("Material
      Disagreement"). Material Disagreement means a matter pertaining to the one
      or more of the matters described below, that comes to a vote at a meeting
      of the Shareholders or a meeting of the advisory board for decision, and
      is decided by the Buyer's exercise of its casting vote (the date of
      Buyer's exercise of its casting vote shall be the "Date of the Material
      Disagreement"): This option may only be exercised within 60 days after the
      Date of the Material Disagreement:

      -     the pursuit by an Atronic Company of business opportunities in a
            geographical territory in which such Atronic Company did not do
            business before;
<PAGE>

                                                                          - 13 -

      -     the pursuit by an Atronic Company of business opportunities outside
            the scope of gaming systems, gaming solutions, gaming machines;

      -     the determination, increase or decrease of an Atronic Company's
            budget for research and development;

      -     the determination, amendment or revision of an Atronic Company's
            annual and/or three-year plan; and/or

      -     other matters that, if acted upon, would have the effect of
            obligating the Shareholders to increase their loans and/or capital
            contributions to a Parent Company.

8.1.3 After expiry of 5 years after the Transaction Date, Shareholders I and II
      may exercise a put option without giving any reasons.

8.2   New Shareholder shall be entitled to a call option regarding the Option
      Interests in the following cases:

8.2.1 12 months after the signing of an agreement providing for a Major
      Acquisition, however at the earliest 12 months after the Transaction Date,
      if Shareholders I and II have not accepted an offer pursuant to Section 6;
      such option may only be exercised within 60 days after expiry of the
      Participation Election Period pursuant to Section 6.2. The consummation of
      the Major Acquisition is a condition precedent for the consummation of
      this option. The right to claim consummation of an exercised option ceases
      to exist if such Major Acquisition does not close within 18 months after
      the Notice of a Major Acquisition. The right to exercise such option
      expires on the fifth anniversary of the Transaction Date.

8.2.2 After expiry of 3 years after the Transaction Date and until the fifth
      anniversary of the Transaction Date if a Material Disagreement pursuant to
      Section 8.1.2 is given;

8.2.3 After expiry of 5 years after the Transaction Date without giving any
      reasons.

8.3   The options shall be exercised by giving a written notice to the grantor
      of the option.

8.4   The purchase price of the Option Interests shall be calculated as follows:

      -     in the cases of Section 8.1.1 and Section 8.1.2 as well as Section
            8.2.1 and Section 8.2.2 based on the following formula ("Formula
            Purchase Price"):

                         CompanyValue - NetFiancialDebt
                         ------------------------------

<PAGE>

                                                                          - 14 -

      -     in the cases of Section 8.1.3 as well as Section 8.2.3 the Purchase
            Price is identical to the "fair value" ("Fair Value Purchase Price")

8.5   For the purposes of determining the Formula Purchase Price the Parties
      agree the following procedure:

8.5.1 The Formula Purchase Price shall be calculated on the basis of a financial
      report to be established by an auditor of the Parent Companies upon
      exercise of the option ("Option Report").

8.5.2 The enterprise value amounts to 7.5 times the EBITDA-value.

8.5.3 The EBITDA-value shall be calculated in accordance with the provisions
      (including exhibits) contained in Section 4.5.1 to Section 4.5.6 and
      Section 4.5.9 of the KV. The Net Financial Debt shall be calculated in
      accordance with the provisions contained in Section 4.6.1 to Section
      4.6.5.

8.5.4 The Option Report shall be established within 6 weeks after the exercise
      of the option on the basis of the four completed quarters preceding the
      receipt of the notice of the exercise of the option. Section 8.5 and
      Section 8.6 of the KV (without Working Capital) shall apply accordingly.

      In case the closing takes place more than six months after the date of
      receipt a further option financial report ("Option Report 2") shall be
      established for the four completed quarters preceding the transaction date
      of the option. This report is to be established within 6 weeks after the
      transaction date of the option. Section 8.5 and Section 8.6 KV (without
      Working Capital) shall apply accordingly.

8.6   The Parties agree upon the following procedure for the purposes of
      determining the Fair Value Purchase Price:

8.6.1 If the Parties are unable to agree on a Fair Value Purchase Price within
      four weeks after the exercise of the option, the Shareholder exercising
      the option as well as the Shareholder granting the option shall each
      appoint an expert experienced in the relevant field of business and
      established in evaluating German private companies with an international
      business to conduct a valuation of the Option Interests. The appointment
      shall take place within 14 days after expiry of the four-week deadline by
      written notice. Said evaluation experts shall be directed to promptly
      select a third valuation expert and inform the Shareholders accordingly.

8.6.2 The three evaluation experts shall, within thirty (30) Business Days of
      the appointment of the third expert, independently determine the fair
      market value of the Option Interests

<PAGE>
                                                                          - 15 -

      within sixty (60) days after appointment of the third expert.

8.6.3 The Parties shall cause the Parent Companies to provide the evaluation
      experts with all information reasonably required by them to conduct their
      evaluations.

8.6.4 The evaluation experts shall be directed to notify the Sellers and the
      Buyer in writing of their valuations (each, an "Evaluation Notice") within
      the aforesaid sixty-day period. The final aggregate purchase price of the
      Option Interests shall be the average of the two valuations that are
      closest to each other. The final aggregate purchase price thus determined
      shall be final and binding on all Shareholders. The evaluation experts
      shall be deemed to act as experts and not as arbitrators.

8.7   The Parties will consummate the transfer of the Option Interests by
      notarial deed on the closing date ("Option Transaction Date"). The Option
      Transaction Date shall be the last day of the calendar month in which the
      Formula Purchase Price or the Fair Value Price are determined pursuant to
      the Option Report in a binding and final manner and any possible obstacles
      to such consummation are eliminated. If the completion time is not 14 days
      the consummation of the option shall be postponed to the last day of the
      following month.

      In deviation of the following provisions in case an option is exercised
      pursuant to Section 8.1.1 and Section 8.2.1 the consummation of the option
      has to take place on the same day, on which the Major Acquisition is
      closed, if possible.

8.8   The purchase price is to be paid concurrently against assignment of the
      Option Interests on the Option Transaction Date.

8.9   In case that an Option Report 2 has to be established a preliminary price
      in the amount of 90% of the purchase price determined on the basis of the
      Option Report is to be paid on the Option Transaction Date. The difference
      between the preliminary price and the price determined on the basis of the
      Option Report 2 shall be due for payment or repayment within three weeks
      after the purchase price has been determined in a binding and final
      manner.

SECTION 9 LOSS OF LICENCE AND SIMILAR CASES

9.1   In the event that either one of the Shareholders I and II (for the
      purposes of the following provision referred to as
      "Gauselmann-Shareholders") becomes an Unsuitable Person, the New
      Shareholder shall be entitled to exercise an immediate Call Option with
      regard to the shares/interests in the Parent Companies and the Atypical
      Silent Partnership of both Gauselmann-Shareholders.

      In the event that the New Shareholder becomes an Unsuitable Person, the
      Gauselmann-Shareholders at their discretion shall be entitled either to
      exercise an immediate Call Option with regard to the shares/interests of
      the New Shareholder in the Parent Companies and the Atypical Silent
      Partnership or to exercise an immediate Put Option with regard to all of
      their own shares/interests in the Parent Companies and the Silent
      Partnership.

9.2   In the cases of Section 9.1 the Purchase Price to be paid shall be
      calculated as follows: In the event that one of these options is exercised
      in the period up to the fifth anniversary of the Transaction Date the
      provisions on the calculation of the Formula Purchase Price shall apply
      accordingly, afterwards the provisions on the calculation of the Fair
      Value Purchase Price shall apply accordingly. The consummation of the Put
      Option or the Call Option shall take place two weeks after the Purchase
      Price has been determined in a binding and final manner and no obstacles
      to such consummation exist.

9.3   With respect to cases of one Shareholder deceasing or ceasing to be
      contractually capable the Parties shall attempt to agree within four
      months after the recording of this Agreement on a regulation taking into
      account the interest of both Parties in accordance with the principle of
      good faith.

                                                                          - 17 -

      (i) each company or entity over which Sellers or Buyer have (separately or
      together) direct or indirect control and/or a right to receive fifty
      percent (50%) or more of the dividends or other from of profit

      "Senior Employee" (as herein below defined) of any Atronic Company or was

SECTION 15 CONFIDENTIALITY

15.1  Each Disclosee of Confidential Information of anther Party hereby agrees
      that it and its representatives will not use or duplicate any Confidential
      Information of the Discloser other than for the purposes of effecting the
      transactions contemplated in this Agreement (including but not limited to
      transactions contemplated in agreements referred to therein) and
      evaluating and monitoring the businesses of the Atronic Companies, and
      that such Confidential Information of Discloser will be kept confidential
      by the Disclosee and its representatives, subject to subsections Section
      15.2 and Section 15.3, provided, however, that Confidential Information
      may be disclosed: (i) to the Disclosee's representatives who need to know
      such information for the purpose of effecting the transactions
      contemplated in this Agreement and evaluating and monitoring the
      businesses of the Atronic Companies (it being understood that each
      Disclosee so disclosing Confidential Information shall inform its
      representatives of the confidential nature of such information and shall
      direct such Representatives to treat such information confidentially), or
      (ii) otherwise as the Discloser may consent in writing. Each Party agrees
      to be responsible for any breach of this Agreement by its representatives.

15.2  For the avoidance of doubt, Confidential Information of any Parent Company
      does not belong to and is not considered property of the Shareholders of
      the Parent Companies. Accordingly, from and after the Closing, absent the
      written consent of a Parent Company, a Shareholder of that company shall
      not use or duplicate Confidential Information of such company other than
      for the purposes of effecting the transactions contemplated in this
      Agreement and evaluating and monitoring the business of the Atronic
      Companies (in the capacity as a Shareholder), and the Shareholder shall be
      obligated to keep such Confidential Information of the Parent Company
      confidential as set forth in Section 15.1.

15.3  In the event a Disclosee or its representatives are requested or required
      by law or the rules of any stock exchange to make a disclosure of
      information which would include Confidential Information of a Discloser,
      the Disclosee so required may make such disclosure without breach of or
      other liability under this Agreement, provided it uses its best efforts to
      notify the Discloser prior to the disclosure regarding the form and
      substance of such disclosure.

15.4  In the event a Disclosee or its representatives are requested or required
      by oral questions, interrogatories, requests for information or documents,
      subpoena, civil investigative demand or other similar process to disclose
      any Confidential Information of Discloser, such Disclosee will provide the
      Discloser with prompt notice of such request or

<PAGE>

                                                                          - 19 -

      requirement so that the Discloser may waive compliance with this Agreement
      or may (entirely at Discloser's cost and expense) challenge the validity
      of such requirement and/or seek an appropriate protective order.
      (Disclosee shall cooperate, when feasible, with Discloser's efforts to
      obtain an appropriate order). However, if, failing the entry of a
      protective order or the receipt of a waiver, such Disclosee or its
      representatives are, in the opinion of their legal counsel, required under
      law, regulation or court order to disclose Confidential Information under
      risk of liability for contempt or other censure or penalty, disclosure of
      such information may be made without breach of or other liability under
      this Agreement.

15.5  Subject to Section 15.2 and Section 15.3, and except as otherwise agreed
      to in writing by the Parties, the Parties each agree that it will not, and
      it will not permit any representative controlled by it, to disclose to any
      person other than its own representatives, either the fact that this
      agreement exists, that a transaction among the Parties has been agreed to,
      and/or any actual or proposed terms or conditions relating to the instant
      transaction, until such information becomes public.

      recording of this deed and continuously thereafter, notwithstanding the
      termination of this Agreement.

      of the Parties hereto and except as specifically provided herein none of
