5.      CONFIDENTIALITY

        5.1 IGT will keep all Confidential Information in confidence and will
not disclose any item of Confidential Information to any person other than its
employees, agents or contractors who need to know the same in the performance of
their duties, and to End-Users in connection with the sublicense granted to

nondisclosure of Confidential Information

                                       4

contractors or any End-User to the same extent it would be liable for
non-compliance by its employees.

        5.2 IGT recognizes that each item of Software and Firmware (i) is

which (i) was in the receiving party's lawful possession prior to the submission
thereof by the disclosing party; (ii) is later lawfully obtained by the
receiving party from a third party under no obligation of secrecy, (iii) is, or
later becomes, available to the public through no act or failure to act by the

without reliance on the Confidential Information by individuals who have not
reviewed the Confidential Information.

6.      DEFAULT

        6.1 IGT shall be deemed to be in default under this Agreement upon the
occurrence of any one or more of the following: IGT (1) detrimentally affects
ACRES' ability to adequately support IGT by refusing or neglecting to implement
ACRES' recommendation for corrective action to resolve any on-going problem; (2)
refuses or neglects to cause installation of Updates; (3) fails to remit to
ACRES its royalty fees or other sums due ACRES under this Agreement; or (4) IGT,
MGM Mirage or any End-User uses the Software and/or Firmware for any purpose
other than as expressly permitted in this Agreement. In the event that IGT fails
to perform any obligation under this Agreement within thirty (30) days after
receipt of written notice of default, ACRES may, at its option, declare all
amounts remaining unpaid under this Agreement immediately due and payable, and
interest shall accrue on the outstanding principal and interest balance at a
rate of 1.5% per month until paid in full. ACRES shall be entitled to recover
attorneys' fees and any other costs of collection, and shall have all rights and
remedies afforded to a secured party pursuant to the laws of the applicable
jurisdiction. No waiver by ACRES, its successors or assigns of any default,
including, but not limited to, acceptance of late payments after the same is
due, shall be construed to be a waiver of any other default or of the same
default on a future occasion.

        6.2 ACRES shall be deemed in default under this Agreement upon the
occurrence of any one or more of the following: ACRES (1) detrimentally affects
IGT's ability to adequately support the End-User by refusing or neglecting to
provide

                                       5
<PAGE>   6
Hardware, Software or Firmware on a timely basis and as determined pursuant to
this Agreement.

7.      TITLE TO AND PROTECTION OF PROPRIETARY MATERIALS

        7.1 The parties hereby acknowledge and agree that the Software, Firmware
and Updates provided to IGT by ACRES are proprietary to ACRES, and are being
licensed and not sold to IGT by this Agreement. Nothing in this Agreement shall
be construed as conferring to IGT the right to sell, lease, transfer to any
third party (other than an End-User), or to otherwise dispose of the Software
and/or Firmware, in whole or in part, without the prior written consent of
ACRES. IGT understands and agrees that the Software and Firmware contain
valuable trade secrets of ACRES, and that such Software and Firmware shall be
held in confidence and not disclosed to any third party without ACRES' prior
written consent.

        7.2 Title to the copyright in all Software, Firmware, and Documentation
is and shall remain in ACRES. IGT may use the Software and Firmware for
demonstration, marketing, testing, and regulatory approval purposes. IGT may
also use the Software and Firmware for the purpose of integrating such Software
and Firmware with IGT's proprietary products for sublicensing to the End-Users
but not for any other productive use. IGT agrees it will not distribute Software
and Firmware except as set forth in Section 2.2. IGT agrees not to alter or
remove any copyright notices or other proprietary notices on or in the Software,
Firmware, Hardware, Documentation or other materials supplied by ACRES, and to
reproduce such notices in any copies furnished to IGT's customers under this
Agreement.

        7.3 IGT acknowledges that ACRES may use, or require IGT to use
ACRES-supplied software locks, or similar security measures, to limit the use of
Software and Firmware consistent with End-Users' use permitted under this
Agreement.

8.      LIMITED WARRANTY

        8.1 ACRES warrants that the Software, Hardware and Firmware will perform
substantially in accordance with the Documentation for a period of ninety (90)
days from the date of live casino operation. ACRES' obligations under this
warranty are limited, at ACRES' option, to replacing or correcting the Software
and/or Firmware, so that it will so perform or accepting a return of the
Software and/or Firmware within such period and refunding the license fee. This
warranty shall not apply to any of the Software or Firmware which shall have
been modified or altered, except by ACRES, or which shall have been subjected to
misuse, negligence or accident except by ACRES.

                                       6
<PAGE>   7
        8.2 WARRANTIES BY IGT TO END-USER. IGT agrees that any and all
warranties made to customers of IGT shall be made only by IGT. IGT acknowledges
and agrees that IGT will make no representations to its customers with respect
to any warranty made by ACRES. IGT hereby agrees to indemnify ACRES for any loss
resulting from IGT's failure to comply with IGT's obligations hereunder with
respect to warranties.

9.      EXCLUSION OF WARRANTIES

        EXCEPT AS EXPRESSLY SET FORTH HEREIN, ACRES GRANTS NO WARRANTIES RELATED
TO THE SOFTWARE OR FIRMWARE OR MAINTENANCE, UPDATE, AND/OR THE OPERATION OF
UPDATES IN CONNECTION WITH THE SOFTWARE AND/OR FIRMWARE, EXPRESS OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE. ACRES NEITHER ASSUMES NOR AUTHORIZES IGT OR
ANY OTHER PERSON TO ASSUME FOR ACRES, ANY WARRANTY EXCEPT AS MAY BE SPECIFICALLY
PROVIDED IN WRITING BY ACRES. NEITHER ACRES NOR ITS VENDORS SHALL BE LIABLE TO
IGT OR THIRD PARTIES FOR INCIDENTAL, SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES,
INCLUDING, BUT NOT LIMITED TO, THE LOSS OF PROFIT OR DAMAGES ARISING FROM THE
LOSS OF DATA OR DATA BEING RENDERED INACCURATE, EVEN IF ACRES HAS BEEN ADVISED
OF THE POSSIBILITY OF SUCH DAMAGES. IN ANY EVENT, ACRES' MAXIMUM LIABILITY UNDER
THIS AGREEMENT SHALL NOT EXCEED THE TOTAL AMOUNT IGT IS OBLIGATED TO PAY ACRES
PURSUANT TO THIS AGREEMENT. THE PROVISIONS OF THIS ARTICLE ARE FUNDAMENTAL
ELEMENTS OF THE BASIS OF THE BARGAIN BETWEEN IGT AND ACRES, AND ACRES WOULD NOT
BE ABLE TO PROVIDE THE SOFTWARE AND FIRMWARE WITHOUT SUCH LIMITATIONS.

10.     TERM OF AGREEMENT

        10.1 The minimum term of this Agreement shall be two (2) years from Live
Operation at each End-User's property (the "Minimum Term"). At the end of the
Minimum Term, this Agreement shall be automatically renewed for additional one
(1) year periods, unless either party notifies the other in writing at least
twenty-five (25) days prior to the expiration of the Minimum term, or any
additional term, that it does not wish to renew this Agreement for an additional
one (1) year period.

        10.2 ACRES may terminate this Agreement at any time effective upon
receipt of written notice in the following circumstances:

                                       7
<PAGE>   8

               (a) IGT's, MGM Mirage's or an End-User's failure to protect the
proprietary interest of ACRES in the Software, Firmware, Updates or Hardware,
including, without limitation, any non-compliance or breach by IGT, MGM Mirage
or any End-User of Section 2 or Section 5 of this Agreement, or
misrepresentation of ACRES proprietary interest therein.

               (b) IGT's Default, as set forth in Section 6 (other than a
Default arising from events that would be covered under Section 10.2(a) above),
that remains uncured for more than thirty (30) days after receipt of written
notice of default; or

               (c) IGT's insolvency, bankruptcy, or inability to pay debts as
and when due, or an assignment for the benefit of IGT's creditors, or the
appointment of a receiver for all or a substantial part of IGT's business or
property, or an attachment of any of IGT's assets lasting more than ten (10)
days.

        10.3   IGT may terminate this Agreement at any time effective upon
receipt of written notice in the following circumstances:

               (a) ACRES' Default, as set forth in Section 6, that remains
uncured for more than thirty (30) days after receipt of written notice of
default;

               (b) MGM Mirage cancels or otherwise terminates its Equipment,
Purchase and Maintenance Agreement with IGT; or

               (c) ACRES' insolvency, bankruptcy, or inability to pay debts as
and when due, or an assignment for the benefit of ACRES' creditors, or the
appointment of a receiver for all or a substantial part of ACRES' business or
property, or an attachment of any of ACRES' assets lasting more than ten (10)
days.

11.     SUPPORT, MAINTENANCE AND REGULATORY APPROVAL

        11.1   ACRES and IGT will enter into a Maintenance Agreement with
respect to support and maintenance of the Software and Firmware by ACRES.

        11.2   The parties agree that the performance by each party of the terms
and provisions of this Agreement is contingent upon obtaining all necessary
approvals from any and all governmental regulatory agencies in any jurisdiction
where they are licensed. Each agrees to fully cooperate with the other in
providing any and all information and documents that may be requested by any
appropriate regulatory agency during the approval process and the due diligence
investigation. This will be a continuing obligation of each party during the
term of the Agreement after it has been initially approved by the regulatory
agencies. In the event that any regulatory agency determines that the Agreement
cannot be approved for any reason, then the parties


                                       8
<PAGE>   9
agree that it shall be considered null and void ab initio. If as a result of
later circumstances a regulatory agency determines that the Agreement cannot
continue, then the parties agree that the Agreement shall terminate as of the
date of that finding. Neither party shall be liable to the other for costs,
expenses, or damages of any kind that result from the failure to perform this
Agreement if such failure results from an unsatisfactory due diligence
investigation, a denied approval from regulatory agency or from a later
determination by such an agency that the Agreement must be terminated.
Notwithstanding any such termination, IGT shall pay all outstanding amounts due
ACRES or return the hardware for a refund at time of termination, unless
prohibited by law or an order from regulatory authorities.

12.     INDEMNIFICATION

        Acres represents and warrants that is has the right to market and
furnish to IGT the Hardware and Software Products and agrees to defend any
action brought against IGT and/or MGM-Mirage based on a claim that the Hardware
and/or Software Products infringe any copyright, trade secret, patent or other
proprietary right. Acres will pay any award against IGT and/or MGM-Mirage, and
any costs and attorneys' fees incurred by IGT and/or MGM-Mirage resulting from
any such claim, provided that IGT has promptly notified Acres in writing of such
claim, and has permitted Acres to direct and control the investigation, defense
and settlement of any such claim. IGT hereby agrees that ACRES shall have no
liability if such alleged infringement arises from other than intended use of
the Hardware, Firmware or Software.

13.     MISCELLANEOUS

        13.1      NOTICES

        Any payment, statement, notice, request, or other communication shall be
deemed to be sufficiently given to the addressee, and any delivery hereunder

Express, to the addresses specified above. Each party to this Agreement may
change its address by giving written notice to the other party.

        13.2      RISK OF LOSS

                                       9
<PAGE>   10
        13.3      TAXES AND DUTIES

        IGT is responsible for any taxes, governmental fees and duties which may
arise as a result of this Agreement or the possession or use of the Software,
Hardware and/or Firmware furnished hereunder.

        13.4      ACCEPTANCE

        The products covered by this Agreement shall be deemed to be finally
inspected and accepted by IGT thirty (30) days after delivery thereof, unless
notice of rejection or notice of any claim, including, without limitation, any
claim for delay in delivery, is given in writing to ACRES within said period.

        13.5      EXPORT

        IGT agrees that, regardless of any disclosure made by IGT to ACRES of an
ultimate destination of the products, IGT will not export or re-export either
directly or indirectly any ACRES products, or any system incorporating said
products, outside of the United States without first obtaining a license from
the United States Department of Commerce or any other agency or department of
the United States government, as required.

        13.6      APPLICABLE LAW

        The laws of Nevada, without reference to its choice of law rules, shall
govern the validity, performance and enforcement of the terms and conditions of
this Agreement, and any other obligations created thereby.

        13.6A     ARBITRATION

        13.6A.1   Any controversies between the Parties arising out of or
relating to this Agreement will, upon demand of either Party, be resolved
exclusively by submission to an arbitrator or a panel of three arbitrators. If
the Parties cannot agree upon a single arbitrator, then each Party will
designate one arbitrator and the two arbitrators designated by them will
designate a third for the panel of three arbitrators. No arbitrator will have
any direct or indirect interest in either Party or the matter submitted for
determination. The arbitration will be conducted in Reno, Nevada or such other
location as may be agreed upon by the Parties.

        13.6A.2   The arbitration will be conducted pursuant to the procedural
rules of the American Arbitration Association as the same may have been or may
be amended, and will be subject to the jurisdiction of the District Court of the
State of Nevada in and for the County of Clark. The arbitrators will grant
discovery liberally.


                                       10
<PAGE>   11
Without limiting the generality of the foregoing, each Party will have: (a) full
access to the records of any other Party that pertain to the subject matter of
the controversy; (b) the power to call for testimony of any director, officer,
employee, agent or representative of any other Party; and (c) all other rights
of discovery afforded to Parties in civil actions under the then applicable
Federal Rules of Civil Procedure (or rules or laws applicable to federal court
proceedings adopted in lieu thereof). A Party's failure to comply with
reasonable discovery requests will be sufficient cause for an adverse finding on
an issue related to such discovery.

        13.6A.3   The arbitrators will render a decision not later than thirty
(30) days after the matter has been submitted, and such decision will be final
and binding upon the Parties. The decision of a panel of three arbitrators will
require the concurrence of at least two arbitrators. The decision will be in
writing. The decision of the arbitrators may be entered as a final decree or
judgment in any court of competent jurisdiction or may be enforced against the
Parties and their assets wherever they are found. The arbitrators are
specifically authorized to grant injunctive relief, either as part of the final
decision or prior to the final decision. The Parties desire that the courts
promptly enforce all injunctive relief granted prior to final decision as though
it were part of a final decision, even though such enforcement may be requested
prior to final decision.

        13.6A.4   Any costs incurred by any arbitration proceedings (such as
compensation to the arbitrators and reporter and the expense of hearing room
facilities) will be divided equally among the Parties, except that each Party
will bear its own attorneys' fees and costs of witnesses; provided, that, the
arbitrators will have the authority to require, as part of the final decision,
the Party against whom the arbitrators render a decision to reimburse any or all
costs, expenses and attorneys' fees incurred by Acres in connection with the
arbitration, and such final decision may be entered as a final decree or
judgment in any court of competent jurisdiction or may be enforced against the
Parties and their assets wherever they are found.

        13.6A.5   The arbitration of any controversy under this section will be
barred if such arbitration is not demanded by a Party in accordance with the
period of time permitted by the statute of limitations under the laws of the
State of Nevada which would be most applicable to an action commenced in the
courts of the State of Nevada based upon such controversy.

        13.6B     EQUITABLE RELIEF

        IGT and ACRES acknowledge that the provisions of this Agreement
pertaining to ACRES' rights to the Hardware, Firmware, Software, Updates and
Documentation are essential to ACRES, and that damages sustained by ACRES as a
result of a breach


                                       11
<PAGE>   12
by IGT or any End-User of such provisions cannot be adequately remedied by
monetary damages alone. Therefore, notwithstanding the arbitration provision set
forth in Section 12.6.A above, IGT agrees that, in addition to any other remedy
ACRES may have under this Agreement or at law, ACRES shall be entitled to
injunctive and other judicial equitable relief to prevent or curtail IGT or an
End-User from breaching the provisions of this Agreement.

        13.7      COSTS AND ATTORNEYS' FEES

        In the event of any dispute with respect to the performance or
enforcement of this Agreement, the prevailing party shall be entitled to recover
its costs, including reasonable attorneys' fees.

        13.8      SUCCESSORS AND ASSIGNS

        Without the prior consent of ACRES, IGT may not assign, transfer, or
sublicense this Agreement or the license or Software specified in the Agreement.
Any attempt to otherwise assign, transfer, or sublicense any of the rights,
duties or obligations hereunder is void.

        13.9      PARTIAL INVALIDITY

        In the event that any term or provision of this Agreement is held by a
court of competent jurisdiction to be invalid, void or unenforceable, the
remainder of this Agreement or the application of such term or provision to
persons or circumstances other than those as to which it is held invalid, void
or unenforceable shall not be affected thereby, and every term and provision of
this Agreement shall be valid and enforced to the fullest extent permitted by
law.

        13.10     CAPTIONS

        Captions contained in this Agreement are for reference purposes only,
and are not part of the Agreement.

        13.11     AMENDMENT

        Neither this Agreement nor any of the attached Exhibits to this

                       HARDWARE SALE TERMS AND CONDITIONS

        1.     SUPPLEMENT TO AGREEMENT. These terms and conditions of sale
govern the sale of hardware products purchased by IGT from ACRES and supplement
the provisions of the Product Sales Delivery, Maintenance and License Agreement
to which these terms are an exhibit. These terms and conditions prevail over any
additional, conflicting or inconsistent terms and conditions appearing on any
purchase order submitted by IGT. Such additional, conflicting or inconsistent
terms or conditions are hereby objected to and shall be of no effect. Failure of
ACRES to object to any provision contained in any order or other communication
from IGT shall not be construed as a waiver of these terms and conditions nor an
acceptance of any such provision. In the event of any conflict between terms and
conditions stated herein and those stated in any order or other communication
from IGT, the terms and conditions stated herein shall govern. This agreement
constitutes the complete and final agreement between the parties relating to the
sale of the products described in the Agreement and its exhibits and supersedes
all previous communications, representations or agreements, either oral or
written, with respect to the subject matter hereof. No change, modification,
rescission, discharge, abandonment or waiver of these terms and conditions shall
be binding upon ACRES unless made in writing and signed on its behalf by an
authorized employee. No course of dealing, usage of trade or course of
performance shall be relevant to explain or supplement any terms and conditions
expressed in this Exhibit.

        2.     DELIVERY DATES.  ACRES and IGT shall jointly confer and agree on
delivery dates. ACRES shall not be liable for any delay in performance hereunder
caused in whole or in part by any unforeseen circumstances or causes beyond the
reasonable control of and without the fault or negligence of ACRES. ACRES
reserves the right to make partial shipments.

        3.     HARDWARE WARRANTY.

               3.1   SCOPE OF WARRANTY. ACRES warrants to IGT that the Hardware
Products will be free of defects in materials and workmanship, under normal use,
upon initial commercial operation and for a period of 90 days thereafter. This
warranty shall be effective only if ACRES receives notice of such defect or
nonconformance during the period of the warranty. ACRES' sole and exclusive


                                       17
<PAGE>   18
liability for breach of warranty shall be (at ACRES' option) to repair or
replace the defective or nonconforming products or credit IGT's account for any
defective or nonconforming products that are returned by IGT during the warranty
period. Products repaired or replaced under this warranty are subsequently
warranted only for the remaining, unexpired portion of the warranty period
applicable to the original products). Defective components that are replaced by
ACRES shall become the property of ACRES. If ACRES elects to repair or replace
the products, ACRES shall have a reasonable time to do so.

               3.2   COMMENCEMENT OF WARRANTY. The warranty period begins on the
date of live casino operation.

               3.3   PLACE OF REPAIR OR REPLACEMENT. In order to obtain the
benefits of this warranty, IGT must return the defective or nonconforming
products to ACRES at its plant in Las Vegas, Nevada, not later than forty five
(45) days after ACRES' receipt of notice of the alleged defect or
nonconformance. IGT shall prepay transportation charges. ACRES shall pay for the
return of the repaired or replaced products to IGT by ground transportation. IGT
shall obtain a Return Material Authorization ("RMA") number from ACRES before
returning any product to ACRES.

               3.4   LIMITATION OF WARRANTY. The foregoing warranty shall not
apply to defects resulting from (a) improper or inadequate maintenance; (b)
modification of the products; (c) operation of the products outside of the
environmental specifications for the products; (d) exposure to surges in
electrical current, improper voltage and other electrical conditions outside the
operational specifications; (e) site preparation or installation; (f) neglect,
misuse or abuse of the products; or (g) integration of the products with other
products not covered by ACRES' warranty. The warranty does not cover the cost to
remove any defective products or to install any products repaired or replaced
under the warranty. This warranty shall not apply to cartons, cases, displays,
cabinets or any products not manufactured by ACRES. When products manufactured
by others are included in a system sold by ACRES to IGT, ACRES shall extend the
original manufacturer's warranty, if any, to IGT to the extent permitted. ACRES
shall not be liable for any change or modification made by IGT or any other
person in the express terms and conditions of the warranty set forth above.
ACRES shall not be responsible for any damage to the products which may result
from improper packaging for shipment to ACRES for warranty repair.

               3.5   TECHNICAL ASSISTANCE. Except as represented in Section 8 of
the Agreement, the warranty set forth above shall not be enlarged, diminished or
affected by, and no obligation or liability shall arise from ACRES' rendering of
technical


                                       18
<PAGE>   19
advice, assistance or service in connection with IGT's selection, purchase or
use of the products furnished hereunder. IGT is not relying on ACRES' skill or
judgment to select suitable products.

               3.6   EXCLUSION OF WARRANTIES. EXCEPT AS SPECIFICALLY PROVIDED
ABOVE IN THIS SECTION 3, SELLER MAKES NO OTHER OR ADDITIONAL WARRANTY, EXPRESS
OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTY OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, DESIGN, CAPACITY, CONDITION, QUALITY,
DURABILITY OR SUITABILITY OF ANY PRODUCTS OR SOFTWARE IN ANY RESPECT. NO IMPLIED
WARRANTY ARISING BY USAGE OF TRADE, COURSE OF DEALING OR COURSE OF PERFORMANCE
IS GIVEN BY SELLER OR SHALL ARISE BY OR IN CONNECTION WITH THIS AGREEMENT AND/OR
CONDUCT OF THE PARTIES IN RELATION THERETO OR TO EACH OTHER, AND IN NO EVENT
SHALL SELLER BE LIABLE ON ANY SUCH WARRANTY. ANY MODEL, SAMPLE, DRAWING OR OTHER
PERFORMANCE STANDARD, DESIGN SPECIFICATION OR REPRESENTATION OF ANY KIND SHOWN
OR FURNISHED TO BUYER, IF ANY, WAS FOR ILLUSTRATIVE PURPOSES EXCLUSIVELY AND
NEITHER DID NOR DOES CONSTITUTE ANY REPRESENTATION OR WARRANTY OF SELLER THAT
ANY PRODUCTS OR SOFTWARE WOULD OR WILL CONFORM THERETO.

        4.     LIMITATION OF REMEDIES AND LIABILITY.

               4.1   The remedies provided herein are IGT's sole and exclusive
remedies. ACRES shall have no responsibility other than, at ACRES' option, to
repair or replace defective or nonconforming goods.

               4.2   IN NO EVENT SHALL SELLER BE LIABLE FOR ANY INDIRECT,
SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF PROFITS) WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER LEGAL THEORY, EVEN IF SELLER WAS ADVISED OF
THE POSSIBILITY OF SUCH DAMAGES.

               4.3   If any disclaimer of warranty or limitation of liability is
found to be unlawful or inapplicable, or to have failed of its essential
purpose, ACRES' liability shall be limited to the amount paid by IGT for the
specific unit of product that caused such liability.

               4.4   ACRES is willing to sell products to IGT only in
consideration of and in reliance upon the provisions contained herein limiting
ACRES' exposure to


                                       19
<PAGE>   20
liability. Such provisions constitute an essential part of the bargain
underlying this purchase and sale of products and have been reflected in the
purchase price and other consideration agreed upon by the parties.

        5. PROTECTION OF PROPRIETARY INFORMATION. Any data or information
received or acquired by IGT relating to the business affairs, correspondence,
customers, finances, methods, the products or technology of ACRES that is not
made available by ACRES to the general public shall be treated by IGT as
confidential and proprietary information of ACRES and shall be protected by IGT
and its employees from disclosure to third parties. The foregoing obligation
shall not include data or information which is now in the public domain, or
which becomes part of the public domain through no fault of IGT prior to the
date of any disclosure. IGT will employ at least the same degree of care that it
uses to protect its own most important confidential information. IGT shall
inform each of its employees to whom it provides access to the products of the
obligations of IGT to keep the products and information pertaining thereto in
confidence. IGT further agrees that it will take all reasonably steps to ensure
that the terms of this provision are not violated by any employee, agent or
customer of IGT.
