| |    |  | hereof, the parties will engage, and share in the costs of, a
recognized independent expert (the Expert) to review relevant
publicly available information using such methods as the Expert
deems appropriate and make a written determination (the
Independent Report) as to the similarity of [*]Provided
Information to LICENSORs Technology included in the Licensed
Property. In performance of his engagement, the Expert will not
be provided with access to [*]Provided Information. The Expert
shall sign a written confidentiality and non-disclosure agreement,
agree that in performance of the engagement he will not breach any
third party agreement to which he is bound, and shall not provide
to LICENSEE, in the Independent Report or otherwise, any
[*]Provided Information. The Independent Report, which the parties
shall endeavor to complete within [*]after the date hereof shall
either (1) confirm, to the extent the Expert can and/or subject to
such assumptions the Expert deems reasonable, that the Licensed
Property is not based upon the [*]Provided Information (the
Independent Confirmation), (2) suggest areas in which the
Licensed Property may be similar to or based on the [*]Provided
Information and recommendations for changes to the Licensed
Property to preclude any such similarities (Experts
Recommendations) or (3) determine that development of the
Licensed Property seems likely to have used or been based on the
[*]Provided Information (Critical Problem). In the event of
Experts Recommendations, LICENSOR and LICENSEE shall mutually
agree on the necessary changes in order to obtain an Independent
Confirmation. LICENSOR will then implement the necessary changes
in order to obtain Independent Confirmation. In the event of a
Critical Problem, LICENSEE may elect to terminate this Agreement,
in which case LICENSOR shall refund the License Fees then paid to
date less LICENSORs demonstrable costs (not including any
overhead or employee/consultant bonuses or benefits) in the
development of the Licensed Property directly incurred under the
terms of this Agreement or under the Letter Agreement; provided
however, if it can be reasonably shown that LICENSOR acted in bad
faith in using [*]Provided Information in the development of the
Licensed Property, LIENSOR shall refund all the License Fees
without any deductions for costs. The parties shall use their
best efforts to cooperate with the Expert. If the anticipated
terms of the Experts engagement prove impractical, the parties
may agree to alternative arrangements designed to achieve as
nearly as possible the same purposes.

a suitable QA period for the Deliverables in each Milestone, and
each such period shall be divided in half (herein, the First Half
QA Period and Second Half QA Period). LICENSEE shall as soon as
reasonably possible, but no less frequently than weekly, notify
LICENSOR of defects, non-conformities and other issues arising
during its QA. If LICENSOR fixes defects or non-conformities
discovered during its QA, it will to the extent practical, provide
such fixes to LICENSEE. LICENSOR shall use its best efforts to
correct defects and non-conformities and otherwise address issues
which arise during the First Half QA Period by the end of the
Second Half QA Period. LICENSOR shall use its best efforts to
correct defects and non-conformities and otherwise address issues
which arise during the Second Half QA Period as soon as possible.

after delivery of such Deliverables with written notice that the
Acceptance Criteria as to the Deliverables has been met, or a

correct such defects and non-conformities and return the corrected
Deliverables to LICENSEE within no more than [*]from receipt of
LICENSEEs Statement of Defects and LICENSEE shall then have up to
an additional [*]to test and evaluate such Deliverable for
conformity to the Acceptance Criteria (the Initial Correction
Cycle). The foregoing process shall continue until the Deliverables

any LICENSEEs Materials required in the development of the SDG
Platform Rev B, LICENSOR must provide written notice to LICENSEE
within [*]of the alleged failure. Any delay caused by LICENSEEs
failure to provide LICENSEEs Materials in a timely fashion, or due

license needed for a feature included in the Specifications, shall
cause a time extension for the applicable Milestone Date equal to
the delay for the Milestone affected by that delay and all
subsequent Milestone Dates, and establishes a new Milestone Date for

| | e. |  | For a period of [*]from the Gaming Regulatory Approval Date,
LICENSOR will support and maintain the Licensed Property at its
cost. Such support and maintenance shall include telephone support,
and any correction or fixes necessary to cause the Licensed Property
to continue to perform in accordance with the Specifications or as
otherwise mutually agreed in writing by the parties. If Critical
Defects are reported to LICENSOR, LICENSOR will use its best efforts
to provide an initial call back within [*]if the report from
LICENSEE is made during normal business hours (i.e. 8 a.m.-5 p.m.
Pacific Time) or within [*]if the report is made outside of normal
business hours, and, regardless of when the report is made, to begin
corrective actions within [*]but in no event more than [*]after
LICENSEES notice. If Serious Defects are reported to LICENSOR,
LICENSOR will use its best efforts to provide an initial call back
within [*], and to begin corrective actions within [*]. If Minor
Defects are reported, LICENSOR will use its best efforts to provide
an initial call back within [*], and begin corrective actions within
[*]. For Critical and Serious Defects problem resolution efforts
will be on-going (i.e. without material interruption in such
efforts). LICENSORS resolution time is dependent on LICENSEE
providing appropriate and sufficient data regarding the defects in
question. Reports of defects and other communication between the
parties regarding resolution of defects shall be made to the parties
indicated in Exhibit F. Either party can change or add to the
person(s) designated as their Support Contact on Exhibit F upon
notice to the other party. LICENSOR shall only be responsible for
correcting defects which can be reasonably shown to relate to code
or other technology contained in the SDG Platform Rev B and any
Derivative Works created by LICENSOR which has been licensed under
Section 2.a(iv). Such support and maintenance shall not require
on-site visits, unless the on-site visit is likely to significantly
increase the chances for correction.

cost, all on reasonable terms to be negotiated in good faith, such
terms to be no less favorable to LICENSEE than the terms LICENSOR

| | j. |  | EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, LICENSOR
EXPRESSLY DISCLAIMS AND MAKES NO OTHER REPRESENTATION OR WARRANTY
OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING BUT NOT
LIMITED TO WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE.
| | -- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

8.       LICENSEE Representations and Warranties:LICENSEE has the right to enter
into this Agreement, is a corporation duly organized, validly existing, and in
good standing under the laws of Delaware, has the power and authority,
corporate or otherwise, to execute and deliver this Agreement and to perform
its obligations hereunder, and has by all necessary corporate action duly and
validly authorized the execution and delivery of this Agreement and the
performance of its obligations hereunder.

9.       Term:The term of this Agreement shall commence on the date first set forth
above and shall continue thereafter in perpetuity unless or until terminated
earlier by mutual agreement of the parties or pursuant to Sections 4.c, 10 or
14.c hereof.



|10. |  | Regulatory Compliance:
|--- |  | ----------------------



| | a. |  | Performance of this Agreement in each jurisdiction is
contingent upon each party possessing or receiving any necessary
initial and continuing approvals and licenses from the regulatory
authorities in each of the jurisdictions where the parties operate
and that have jurisdiction over the parties or the subject matter of
this Agreement. Each party shall cooperate with any requests,
inquiries or investigations of any regulatory authorities or law
enforcement agencies. If any license or approval necessary for
either party to perform under this Agreement is denied, suspended,
or revoked, this Agreement shall terminate immediately, and the
parties shall engage in good faith negotiations to provide for an
appropriate fee proration, and neither party shall have any
additional rights hereunder; provided, however, that if the denial,
suspension, or revocation affects performance of this Agreement, in
part only (e.g. in a jurisdiction), the parties shall continue to
perform under this Agreement to the extent it is unaffected by the
denial, suspension, or revocation.

|
| | b. |  | The parties acknowledge that each party operates under
privileged licenses in a highly regulated industry, maintains a
compliance program to protect and preserve its name, reputation,
integrity, and good will through a thorough review and determination
of the integrity and fitness, both initially and thereafter, of any
person or company that performs work for the parties or their
respective Affiliates, or with which those companies are otherwise
associated, and to monitor compliance with the requirements
established by gaming regulatory authorities in various
jurisdictions around the world. Each party shall cooperate with the
other party and its compliance committee as reasonably requested and
provide the committee

| |    |  | with such information as it may reasonably request on appropriate
notice. Either party may terminate this Agreement in the event
that either party or its respective compliance committee discovers
facts with respect to the other party or this Agreement that
would, in the reasonable opinion of that party or its committee or
both, jeopardize the gaming licenses, permits, or status of that
party or any of its Affiliates, with any gaming commission, board,
or similar regulatory or law enforcement authority. If reasonable
and appropriate, the parties may provide notice of, and attempt to
resolve, any problems and concerns, relating to such facts. In
the event of such termination, the parties shall engage in good
faith negotiations to provide for an appropriate fee proration.

|
| | c. |  | Where references are made in this Section 10 to appropriate
fee proration it is intended that fees paid or payable by LICENSEE
to LICENSOR would be reduced or refunded on a proportionate basis to
reflect the relative reduction in revenues reasonably anticipated to
be suffered by LICENSEE as a result of termination or revision of
this Agreement and the licenses granted hereunder, in whole or in
part, as compared to revenues reasonably anticipated had this
Agreement or such license not been so terminated or revised.
Appropriate fee proration shall also consider additional factors
such as the basis of termination and the relative degree of fault of
the parties.                                                                                                               



|11. |  | Confidentiality:
|--- |  | ----------------



| | a. |  | In connection with this Agreement, either party may disclose
Confidential Information to the other. In such event, the party
receiving Confidential Information (Receiving Party) shall hold
in confidence all Confidential Information disclosed to it by the
other party (Disclosing Party) until such time, if ever, that
such Confidential Information becomes available to the public
without breach of this Agreement or the Receiving Party is
authorized in writing by the Disclosing Party to disclose such
Confidential Information as set forth in such writing. A
Receiving Party shall not disclose any Confidential Information of
the disclosing party to any third person, except to the Receiving
Partys employees, agents, consultants, or contractors or
requesting regulatory authority or to Game Developers or Game
Manufacturers, in each instance, who have a reasonable need to
know such information and only to the extent necessary to exercise
rights permitted in this Agreement and in connection with the
performance of this Agreement. The Receiving Party shall be
responsible to the Disclosing Party for any violation of the terms
hereof by any of the employees, agents or consultants,
contractors, Game Developers or Game Manufacturers of the
Receiving Party. In addition to the foregoing, the Receiving
Party shall safeguard the Confidential Information of the

| |    |  | Disclosing Party with the same degree of care that it utilizes to
safeguard its own proprietary information of a similar character,
and in any case shall use reasonable care to safeguard such
Confidential Information. No Receiving Party shall use
Confidential Information of the Disclosing Party except in the
furtherance of this Agreement, unless otherwise expressly
authorized to do so in writing by the Disclosing Party.

| | b. |  | Confidential Information means any information disclosed by
the Disclosing Party to the Receiving Party pursuant to this
Agreement in a context which would cause a reasonable person to
believe the information is intended to be treated as confidential,
including but not limited to, the Licensed Property and documents
expressly designated as confidential, and information related to
either partys manufacturing processes, products, employees,
facilities, equipment, security systems, information systems,
finances, product plans, marketing plans, suppliers, or
distributors; provided, however that Confidential Information
shall not include information that: (i) is now available or becomes
available to the public without breach of this Agreement; (ii) is
explicitly approved for release by written authorization of the
Disclosing Party; (iii) is lawfully obtained from a third party or
parties without a duty of confidentiality to the Disclosing Party;
(iv) is of a type typically disclosed to a third party by the
Disclosing Party without a duty of confidentiality; (v) is known to
the Receiving Party prior to disclosure; or (vi) is at any time
developed by the Receiving Party independently of any such
disclosure(s) from the Disclosing Party. Notwithstanding anything
to the contrary herein, the Licensed Property shall be considered
Confidential Information of each of the parties hereto and may only
be disclosed pursuant to the terms contained herein.

12.      Insurance Obligations: Each party shall purchase and maintain (and shall
pay all premiums and deductibles related to) commercial liability insurance,
including products liability, for the Licensed Property from a recognized and
qualified insurance company naming the other party as additional insured in the
amount of at least [*]million per occurrence against any claims, suits, losses
or damages, including attorneys fees, arising out of any alleged defects in or
the packaging, manufacture, marketing, distribution, sale or use of the
Licensed Property. The insurance purchased and maintained by LICENSOR shall
include errors and omissions insurance. Such policies shall be non-cancelable
except after thirty (30) days prior written notice to the other party.

|13. |  | Indemnification; Limitation of Liability:
|--- |  | -----------------------------------------



| | a. |  | Each party hereto agrees to indemnify and hold the other
(including officers, directors, agents and employees of such party
or its Affiliates) harmless against any loss, damage, expense or
cost, including reasonable attorneys fees (collectively, Damages)
arising out of or in connection with, resulting from or relating to
any breach of any of such partys warranties or representations set
forth in Sections 7 or 8 above, respectively (Indemnified Claims).
Each party shall promptly inform the other in writing of any such
Indemnified Claim.

|
| | b. |  | In connection with any Indemnified Claims, the party so
indemnifying (the Indemnitor) agrees to defend, contest or
otherwise protect the indemnified party (the Indemnitee) against
any such suit, action, investigation, claim or proceeding at the
Indemnitors own cost and expense. The Indemnitee shall have the
right, but not the obligation to participate, at its own expense, in
the defense thereof by counsel of its own choice. In the event that
the Indemnitor fails to notify Indemnitee in writing that it will
defend, contest or otherwise protect against any such Indemnified
Claim within ten (10) days after written notice from the Indemnitee,
the Indemnitee shall have the right upon five (5) days written
notice to the Indemnitor to defend, contest or otherwise protect
against the same and make any compromise or settlement thereof and
recover the entire cost thereof from the Indemnitor, including
without limitation, reasonable attorneys fees, disbursements and
all reasonable amounts applied as a result of such suit, action,
investigation, claim or proceeding or compromise or settlement
thereof. The obligations hereunder shall survive any termination or
expiration of this Agreement.
|
| | c. |  | Anything herein to the contrary notwithstanding, if
LICENSEES use of the Licensed Property as permitted by this
Agreement is enjoined due to an Indemnified Claim for which LICENSOR
is required to indemnify LICENSEE (LICENSORs Indemnified Claim),
LICENSOR will, at its sole expense, either: (i) procure for LICENSEE
the right to continue to exercise its rights under the License, or
(ii) replace the Licensed Property with non-infringing,
substantially equivalent products or functionality, or (iii)
suitably modify the Licensed Property so that it is not infringing;
or, (iv) in the event (i), (ii) and (iii) are not achievable on
commercially reasonable terms or in a commercially reasonable
manner, at LICENSEEs option, accept return of the Licensed Property
and refund to LICENSEE all License Fees paid to LICENSOR under this
Agreement. In the event that (1) LICENSEEs use of the Licensed
Property as permitted by this Agreement is enjoined other than due
to a LICENSORs Indemnified Claim or (2) after the date hereof
either party discovers that the Licensed

shall be liable for any incidental, consequential, punitive or
indirect damages of the other arising out of or in connection with
this Agreement. Except with respect to LICENSORS Indemnified
Claims, in any action arising out of contract, negligence, strict
product liability, tort or warranty the maximum amount of any
recovery against LICENSOR by LICENSEE shall be limited to the
aggregate fees paid or payable to LICENSOR under Section 3 of this
Agreement.

14.      Security Interest:In order to secure LICENSORS obligations to indemnify
LICENSEE under Sections 13.a, and to return or refund License Fees paid as
provided for in Section 4.c, 13.c or Exhibit D (the Obligations), LICENSOR
hereby grants to LICENSEE a first priority security interest in and to (a) SDG
Platform Rev A and SDG Platform Rev B, (b) all Intellectual Property and
LICENSORS Technology embodied therein, (c) all of LICENSORs documentation
relating to the foregoing, and (d) General Intangibles and Proceeds (as defined
in the Uniform Commercial Code in effect in Nevada) relating to or of any of
the foregoing, in all cases now existing or hereafter developed (all of the
foregoing hereafter shall be collectively referred to as Collateral).
Notwithstanding the foregoing, product(s) utilizing SDG Platform Rev A and SDG
Platform Rev B shall not be deemed Collateral and shall be and remain the
property of LICENSOR. LICENSOR shall have the sole and absolute right to sell,
lease or license product(s) in the ordinary course of business utilizing SDG
Platform Rev A and SDG Platform Rev B without any form of security interest
attaching to either the product(s) or any proceeds generated from them.
LICENSOR shall execute and/or deliver to LICENSEE, at any time at the request
of LICENSEE, all agreements, instruments or documents that LICENSEE reasonably
may request, including a more formal security agreement, in a form and
substance acceptable to LICENSEE, to perfect and maintain perfected LICENSEEs
first priority security interest in the Collateral, including, without
limitation, filings with the U.S. Patent and Trademark Office. LICENSOR hereby
authorizes LICENSEE to file UCC-1 Financing Statements and to take any other
steps necessary to perfect and maintain the perfection of LICENSEEs first
priority lien on the Collateral and hereby appoints LICENSEE as its agent and
attorney-in-fact to execute and/or perform on its behalf all agreements,
documents or instruments necessary to carry out the obligations of LICENSOR
hereunder. LICENSOR shall not grant a security interest in or permit a lien,
claim or encumbrance upon any of the Collateral after the date hereof, except

financing statement. Provided the Collateral has not been previously

Date (i.e Milestone 4C), it being understood that no such submittal shall
be made prior to the Acceptance Criteria for all the prior Deliverables
having been met, and (2) Milestone 4E with respect to a Jurisdiction is
ultimately met (A) without any issues relating to the Licensed Property
having been raised by the Jurisdiction during field trials that result in
delays to the Approval Date of the Licensed Property and (B) with respect
to any issues relating to the Licensed Property raised prior to the start
of the field trials by the Jurisdiction, LICENSOR has fixed the problem
and delivered to LICENSEE such fix in an update to the Licensed Property
such that such issues do not create a delay in the Approval Date of the
Licensed Property; then regardless of the actual Approval Date, the
Approval Date for the Jurisdiction for purposes of (c) above shall be
deemed to be the Milestone Date.

Approval Date for a Jurisdiction shall be calculated as the earlier of
the actual date regulatory approval is awarded, or the Approval Date as
