                                                                     PAGE 7


         2.3.3  The Responsible Party warrants that the Documentation delivered
pursuant to paragraph 2.3.2 will conform to the applicable Specifications and
will be sufficient to permit the other Party to effectively Make and Use the
applicable Product and any related Tool.

    Unless otherwise provided in the applicable R&D Plan, the Responsible Party
will obtain any and all approvals, permits, licenses, certificates, listings,
registrations and other authorizations of any governmental authority (e.g.,
state gaming regulatory authorities), independent testing organizations (e.g.,
Underwriters Laboratories or its successors) or other Third Parties specified in
the R&D Plan or required to Make, use, market, sell or distribute Products in
the United States of America.  

    2.5  SCHEDULE

         2.5.1  The Responsible Party will use its best efforts to perform and
complete the R&D Work with respect to any Product in accordance with the 
schedules set forth in the R&D Plan for such Product and any other schedules 
that may be agreed upon from time to time by the Parties.  The Responsible 
Party will perform with reasonable diligence any R&D Work for which no 
schedule is set forth in the applicable R&D Plan or otherwise agreed upon by 
the Parties.

         2.5.2  Neither Party will be liable for any delays in connection with
the R&D Work due to causes that are not reasonably foreseeable, that are beyond
such Party's reasonable control and that cannot be overcome by the exercise of
reasonable diligence; provided that such Party gives the other Party prompt
written notice of the circumstances causing the delay, the anticipated duration
of the delay and the action being taken to overcome or mitigate the delay.  The
Parties will use their best efforts to eliminate or minimize any such delay.  In
the event of any delay within the purview of this paragraph, the schedules for
performance of the R&D Work affected by such delay shall be equitably adjusted
to reflect the delay.

    2.6  PERFORMANCE OF R&D WORK

efficient, expeditious, skillful and workmanlike manner.

         2.6.2  Upon the other Party's request, the Responsible Party will
cooperate with the other Party and coordinate the R&D Work with any related work
being performed by the Responsible Party or others.  If any part of the R&D Work
depends on the results of work by the other Party or others, the Responsible
Party will immediately notify the other Party in writing of any actual or
apparent deficiencies or 

                                                                     PAGE 8


defects in such other work that render it unsuitable for performance of the 
R&D Work in accordance with this Agreement.  The Responsible Party's failure 
to so notify the other Party  will constitute the Responsible Party's 
acknowledgment that such other work is suitable for performance of the R&D 
Work in accordance with this Agreement, except as to latent defects which may 
subsequently be discovered in such other work.

    2.7  FUNDING

    The Parties will fund the R&D Work to be performed under any R&D Plan as
provided for in such R&D Plan.

    other Party under this Agreement;

         (b)  the Specifications and Documentation; and

         (c)  the schedules for performance of any R&D Work.

No such changes will become effective unless and until they are agreed to in
writing by both Parties.  Neither Party will unreasonably withhold its consent
to any change requested by the other Party.

         2.8.2  If any change under paragraph 2.8.1 results in any increase or
decrease in the Parties' reasonable best estimate of the costs that will be
incurred to perform the R&D Work not then performed in accordance with this
Agreement, then the budget, funding and other applicable provisions of the
affected R&D Plan will be amended to reflect such increase or decrease.

         2.8.3  If any change under paragraph 2.8.1 results in an increase or
decrease in the Parties' reasonable best estimate of the time required to
perform any R&D Work not then performed in accordance with this Agreement, then
the schedules and other applicable provisions of the affected R&D Plan will be
amended to reflect such increase or decrease.

                                                                     PAGE 9    




     2.9      CONTRIBUTIONS OF EQUIPMENT

     Each Party will contribute to any R&D Work a reasonable quantity of 
hardware products it produces for use in the R&D Work at prices equal to

SECTION 3.    PURCHASE OF PRODUCTS   

      3.1     ORDERS

      The Responsible Party will Make, sell and deliver to the other Party

this Agreement from time to time.  Each Order will specify a description of 
the Products ordered, the quantity and purchase price of the Products 
ordered, the dates upon which the Products are to be shipped and delivered, 
the destination to which the Products are to be shipped and any applicable 
shipping instructions (e.g., as to carrier or means of shipment); provided, 
however, that unless otherwise agreed by the Responsible Party, the other 
Party will not specify a date for delivery of any Product less than sixty 
(60) days after the date of the Order.  Each Order will be deemed to include 
and be subject to the Purchase T&Cs.     

      3.2     PRICE

      The purchase price for each Product will be as agreed upon from time to 
time by the Parties, subject to the limitation set forth in paragraph 3.3.  
The Responsible Party's acceptance of any Order will constitute the 
Responsible Party's acknowledgment that the purchase price specified in such 
Order has been agreed to by the Responsible Party.  The Responsible Party's 
acceptance of any Order may be evidenced by the Responsible Party's written 
acceptance of the Order, shipment of the Products subject to the Order, or 
any other commercially recognized means of acceptance.   

      3.3     PRICE LIMITATION
     
      The Responsible Party will offer to sell Products to the other 
Party under this Agreement at a fair price that does not exceed

any Third Party, taking into consideration volume, payment terms, delivery 
schedule and other pertinent factors.

                                                                      PAGE 10

consistently applied. Upon the other Party' request, the Responsible Party 
will make such books and records available for examination, reproduction and 
audit by an independent accounting firm designated by the other Party.  
Unless otherwise agreed by the Parties, any such examination, reproduction 
and audit will be conducted during the Responsible Party's normal business 
hours and in such a manner so as not to unreasonably interfere with the 
Responsible Party's business.     

      3.5     PRODUCT DEFECT NOTIFICATION

      The Responsible Party will immediately notify the other Party of any 
material or recurring defect, deficiency or nonconformity in any Product that 
comes to the attention of the Responsible Party.

such other Party's rights, titles and interests in any Joint Technology or 
related Proprietary Rights. 

         5.2.2  If either Party makes any filing, application, registration 
or other action with any governmental authority in order to evidence, perfect

disclosure of any trade secrets included in such Proprietary Rights as such 
Party exercises with regard to its own trade secrets.     

      5.3     NO RIGHT TO ACCOUNTING
     
      Except as otherwise provided in the applicable R&D Plan or a separate 
written agreement entered into by the Parties after the date of this

other Party's commercial exploitation of any Joint Technology or related 
Proprietary Rights.

      5.4     NO RIGHT TO IMPROVEMENTS

     Except as otherwise provided in the applicable R&D Plan or a separate

      5.5     INFRINGEMENT BY THIRD PARTIES

      If either Party becomes aware of any infringement, wrongful use or 
misappropriation of any Joint Technology or related Proprietary Right by any 
Third Party, such Party will give the other Party notice thereof.  Either 
Party may commence and prosecute any legal action that it deems appropriate 
on account of such infringement, wrongful use or misappropriation, and the 
other Party will have the opportunity to participate in any such action.  Any 
recovery in such action will be applied first to reimbursement of the costs 
and expenses (including, but not limited to, attorneys' fees) incurred in 
connection with such action and then to the Parties in proportion to their 
respective damages suffered on account of the infringement, wrongful use or 
misappropriation.   

      5.6     INFRINGEMENT BY JOINT TECHNOLOGY

         5.6.1  If any Joint Technology is held to infringe, 
wrongfully use or misappropriate any Third-Party Right, the Responsible Party

not infringe, wrongfully use or misappropriate any Third-Party Right; or

                                                                      PAGE 13


         5.6.2 Each Party represents and warrants that the Joint Technology 
developed by that Party as Responsible Party will not infringe or 
misappropriate any Third-Party Right.  Each Party will defend and indemnify 
the other from and against any and all claims that any Joint Technology 
developed by that Party as Responsible Party infringes or misappropriates any 
Third-Party Right and any and all costs and expenses (including, but not 
limited to, reasonable attorneys' fees) incurred in connection with the 
defense, settlement or satisfaction of such claim (including, but not limited 
to, any damages, liabilities or losses based upon any such claim); provided 
that the other Party: 

         (a)   gives the Responsible Party prompt written notice of
      the claim;

         (b)   cooperates with the Responsible Party in connection

      unreasonably withheld.

         5.6.3 The Parties' obligations under paragraphs 5.6.1 and 5.6.2 
will not apply to the extent any Joint Technology infringes, wrongfully uses 
or misappropriates any Third-Party Right solely as a result of a Responsible 
Party's Use of any Technology of the other Party in accordance with the 
license granted under paragraph 7.2.

SECTION 9.    ARBITRATION 

      9.1     SELECTION OF ARBITRATOR

      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.  If the two arbitrators designated by the 
Parties cannot agree upon the third arbitrator, then, upon request of any 
party, the third arbitrator will be appointed by the Court as specified in 
paragraph 9.3.  No arbitrator will have any direct or indirect interest in 
either Party or the matter submitted for determination.

      9.2  LOCATION

      The arbitration will be conducted in Portland, Oregon or such other 
location as may be agreed upon by the Parties. 


                                                                       PAGE 17



      9.3     JURISDICTION

      The arbitration will be conducted pursuant to the Oregon Arbitration 
Act, as the same may have been or may be amended, and will be subject to the 
jurisdiction of the Circuit Court of the State of Oregon in and for the 
County of Multnomah.

      9.4     DISCOVERY

      The arbitrators will grant discovery liberally.  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.

      9.5     DECISION

      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.

      9.6     COSTS 

      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 

                                                                       PAGE 18



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. 

      9.7     STATUTE OF LIMITATIONS

      The arbitration of any controversy under this section will be barred if 
such arbitration is not demanded by a Party in accordance with paragraph 7.1 
within the period of time permitted by the statute of limitations under the 
laws of the State of Oregon which would be most applicable to an action 
commenced in the courts of the State of Oregon based upon such controversy. 

SECTION 10.   MISCELLANEOUS 

      10.1    NO RIGHT TO MARKS

      This Agreement will not be interpreted or construed as granting or 
transferring to either Party any license, right, title or interest in or to 
any Mark of Acres.  Neither Party will use any Mark of the other Party 
without the prior written consent of such other Party.

      10.2    CONFIDENTIAL INFORMATION

Information of the Disclosing Party.  The Receiving Party will treat such 
Confidential Information as confidential and proprietary of the Disclosing 
Party and will use such Confidential Information solely for the purposes for 
which it is provided by the Disclosing Party. Without limiting the generality 
of the foregoing, the Receiving Party will take reasonable precautions to 
prevent any unauthorized use or disclosure of such Confidential Information 
and will protect such Confidential Information from unauthorized use or 
disclosure at least to the same extent that it protects its own Confidential 
Information of a similar nature from unauthorized use or disclosure.  The 
obligations under this paragraph will not apply to any: 

         (a)  use or disclosure of any information pursuant to the exercise
       of the Disclosing Party's rights under this Agreement; 

         (b)  information that is now or later becomes part of the public
       domain through no fault of the Receiving Party;

         (c)  information that is obtained by the Receiving Party from a Third
      Party (other than in connection with this Agreement) who was not under
      any  obligation of secrecy or confidentiality with respect to such 
      information;   

         (d)  information that is independently developed by the Receiving Party
      (e.g., without reference to any Confidential Information); 

         (e)  any disclosure required by applicable law (e.g., pursuant to
      applicable securities laws or legal process), provided that the Receiving
      Party will use reasonable efforts to give advance notice to and cooperate
      with the Disclosing Party in connection with any such disclosure; and 

         (f)  any disclosure with the consent of the Disclosing Party. 

      10.3    COMPLIANCE WITH LAWS

      In the performance of this Agreement, each Party will comply with all 
applicable laws, regulations, rules, orders and other requirements, now or 
hereafter in effect, of governmental authorities having jurisdiction.  
Without limiting the generality of the foregoing, each Party will pay, 
collect and remit such taxes as may be imposed with respect to any 
compensation, royalties or transactions under this Agreement in accordance 
with applicable laws, rules, regulations and orders of governmental 
authorities having jurisdiction.  

      10.4    NOTICES

     Any notice or other communication under this Agreement given by any 
Party to any other Party will be in writing and will be delivered in person 
or mailed, properly addressed and stamped with the required postage, to the 
intended recipient at its address specified below its signature at the end of 
this Agreement and to the attention of the individual who executed this 
Agreement on behalf of such Party.  Any Party may from time to time change 
such address or individual by giving Acres notice of such change in 
accordance with this paragraph.     

      10.5    NONWAIVER

      The failure of either Party to insist upon or enforce 
strict performance of any of the provisions of this Agreement or to exercise 
any rights or remedies under this Agreement will not be construed as a waiver 
or relinquishment to any extent of such Party's right to assert or rely upon 
any such provision, right or remedy in that or any other instance; rather, 
the same will remain in full force and effect.    

                                                                       PAGE 20



      10.6    SUCCESSORS AND ASSIGNS

      Neither Party will assign this Agreement or any of its rights, title or 
interest under this Agreement (voluntarily, involuntarily, by operation of 
law or otherwise) without the prior written consent of the other Party.  No 
assignment by either Party, with or without the consent of the other Party, 
will relieve or release the Party making the assignment from any of its 
obligations under this Agreement.  Subject to the foregoing, this Agreement 
will be binding upon, inure to the benefit of and be enforceable by each of 
the Parties and their respective successors and assigns.
