5. If such claim for indemnity arises in connection with a legal action
instituted by a third party ("Third Party Claim"), the Indemnified Party hereby
agrees that, within five (5) business days after it is served with notice of the
assertion of any Third Party Claim for which it may seek indemnity hereunder,
the Indemnified Party will notify the Indemnifying Party in writing of such
Third Party Claim.

     The Indemnifying Party shall, within five (5) business days after the date
that the Indemnified Party gives notice of a claim (whether a Third Party Claim
or otherwise) as provided above, notify the Indemnified Party whether it accepts
or contests its obligation of indemnity hereunder as claimed by the Indemnified
Party.

     If the claim for indemnity arises in connection with a Third Party Claim
and the Indemnifying Party accepts its indemnity obligation hereunder, the
Indemnifying Party shall have the right, after conceding in writing its
obligation of indemnity hereunder, to conduct the defense of such action at its
sole expense through counsel reasonably acceptable to the Indemnified Party. The
Indemnified Party shall cooperate in such defense is reasonably necessary to

Indemnifying Party with reasonable access to such records as may be relevant to
its defense. The Indemnifying Party shall be entitled to settle any such Third
Party Claim without the prior written consent of the Indemnified Party provided
that the Indemnifying Party provides the Indemnified Party with reasonable
assurances that the Indemnified Party will be fully indemnified by the
Indemnifying Party in connection with any such Third Party Claim. The
Indemnified Party shall be entitled to retain its own counsel at its own expense
in connection with any Third Party Claim that the Indemnifying Party has elected
to defend. If the Indemnifying Party accepts its indemnity obligations hereunder
in connection with a Third Party Claim but elects not to conduct the defense
thereof, the Indemnified Party may defend and/or settle such Third Party Claim
and shall be entitled to be indemnified for the full amount of such claim and
all costs and expenses, including attorneys' fees, incurred in connection
therewith pursuant to this Article 5.

     If the claim for indemnity arises in connection with a Third Party Claim
and the Indemnifying Party contests or does not accept its indemnity obligation
hereunder, the Indemnified Party shall have the right to defend and/or settle
such Third Party Claim and thereafter seek indemnity from the Indemnifying Party
pursuant to this Article 5; provided, however, that the Indemnified Party shall
not settle any such claim without the prior written consent of the Indemnifying
Party, which consent shall not be unreasonably withheld.

6.   CONFIDENTIALITY.  Except as otherwise agreed in writing signed by both
parties, neither DBI nor Manufacturer shall, or permit their Affiliates or their
respective shareholders, directors, officers, employees and agents to, divulge,
disclose, or otherwise communicate directly or indirectly, for any purpose or
for the benefit of any other Person, any confidential or proprietary information
relating to either of their respective businesses, products or services, except
as may reasonably be necessary for the installation, operation, maintenance and
repair of Display Systems utilizing Manufacturer's Components, provided that
each Person receiving such confidential or proprietary information for such
limited purpose shall agree in writing to be bound by the provisions of this
Article 6.  Each party acknowledges that confidential and proprietary
information shall not include any:  (a) information which is or becomes part of
the public domain through no fault of the other party hereto or any of its
Affiliates; or (b) information required to be disclosed by judicial action,
provided that immediately after either party receives notice of such judicial

order either or both parties to take or refrain from taking certain actions
required or prohibited by this Agreement.  Notwithstanding the foregoing, in the
event either party hereto determines in its reasonable discretion that its
rights hereunder would be significantly impaired unless it were able to obtain
temporary injunctive relief, such party shall have the right to petition any

7.2, prior to submitting any dispute to arbitration in accordance with this
Section 7.3

jurisdiction in Las Vegas, Nevada and irrevocably waives any (a) right of
immunity that such party may now have or hereafter acquire from service of
process or the jurisdiction of the aforesaid courts and (b) any objection that
such party may now have or hereafter acquire to the laying of venue of any such
suit, action or proceeding in any such court. The parties hereby irrevocably
accept and submit themselves to the jurisdiction of such courts in any such
suit, action or proceeding, and agree that final judgment (with the exhaustion
of all appeals) shall be conclusive and binding in any jurisdiction in which
such party resides or owns property.

inure to the benefit of the parties hereto and their respective successors,
assigns and legal representatives. Neither this Agreement, nor any right or
