                          SANTA FE GAMING CORPORATION
                  1995 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

Section 1.  Purpose of Plan

The purpose of this 1995 Non-Employee Director Stock Option Plan (the "Plan") of
Santa Fe Gaming Corporation, a Nevada corporation (the "Company"), is to enable
the Company to attract non-employee directors and further align their interests
with those of the stockholders by providing for or increasing their proprietary
interests in the Company.

Section 2.  Persons Eligible Under Plan

Any member of the Board of Directors of the Company (the "Board") who is not an
employee of the Company or any of its subsidiaries (a "Non-Employee Director")
shall be eligible for the grant of Options (as hereinafter defined) hereunder.

Section 3.  Options

(a) Each person who is a Non-Employee Director immediately following the annual
meeting of the stockholders of the Company held in 1996 (an "Annual Meeting")
shall, on the date of such Annual Meeting, automatically be granted an option to
purchase 12,500 shares of the Common Stock, par value $.01 per share, of the
Company (the "Common Shares"), subject to adjustment as provided in Section 7
hereof (an "Option").

(b) In addition, each person who first becomes a Non-Employee Director after the
Annual Meeting shall, on the date such person becomes a Non-Employee Director,
automatically be granted an Option to purchase 12,500 Common Shares, subject to
adjustment as provided in Section 7 hereof.

(c) Notwithstanding the foregoing, if, on any date upon which Options are to be
granted hereunder, the number of Common Shares remaining available for issuance
under this Plan is insufficient for the grant of Options to purchase the total
number of Common Shares specified in Section 3(a) and (b) hereof, then each Non-
Employee Director entitled to receive an Option on such date shall be granted an
Option to purchase a proportionate amount of the available number of Common
Shares (rounded down to the greatest number of whole shares).

(d) Each Option shall be evidenced by a written option agreement that shall
contain the following terms and provisions:

          (i)   The exercise price per Common Share shall be equal to the
                greater of (A) the Fair Market Value (as hereinafter defined) of
                one Common Share on the date of grant of such Option or (B) the
                par value of one Common Share. The "Fair Market Value" of a
                Common Share shall be equal to the last sale price, regular way,
                of a Common Share on the next preceding business day, or in case
                no such sale takes place on such day, the average of the closing
                bid and asked prices, regular way, in either case as reported in
                the principal consolidated transaction reporting system
<PAGE>

                with respect to securities listed or admitted to trading on the
                principal national securities exchange on which the Common
                Shares are listed or admitted to trading or, if the Common
                Shares are not listed or admitted to trading on any national
                securities exchange, the last quoted price in the over-the-
                counter market, as reported by the National Association of
                Securities Dealers, Inc. Automated Quotations System or such
                other system then in use or, if on such day the Common Shares
                are not quoted by any such organization, the average of the
                closing bid and asked prices as furnished by a professional
                market maker who makes a market in the Common Shares and who is
                designated by the Board.

          (ii)  Payment of the exercise price of the Option shall be made in
                full in cash or by check concurrently with the exercise of the
                Option.

          (iii) The Option shall be nontransferable by the optionee other than
                by will or the laws of descent and distribution, and shall be
                exercisable during the optionee's lifetime only by the optionee
                or the optionee's guardian or legal representative.

          (iv)  The Option will be fully vested on the date of grant and shall
                expire upon the first to occur of the following: (A) the third
                anniversary of the date upon which the optionee shall cease to
                be a Non-Employee Director, or (B) the tenth anniversary of the

interpretation arise, these shall be resolved by the Board.

Business.  At the Closing, all right, title and interest of Seller in the
Intellectual Property Assets will be transferred to Buyer.  To the knowledge of
Seller, no third party is infringing, misusing or misappropriating any of the

and directors of Seller and former employers of all current and former
employees, consultants, officers and directors of Seller.

are currently no claims or assertions filed or, to the knowledge of Seller,
threatened against Seller which allege a failure of any of the OEU Products to

Transferred Agreement is valid, binding and enforceable in accordance with its

changes in operation resulting solely from date changes occurring on and after
December 31, 1999; (2) where appropriate, respond to two digit date input in a
way that resolves the ambiguity as to century in a disclosed, defined and pre-
determined manner; (3) where appropriate, store and provide output of date

Business or the Purchased Assets at law or in equity or otherwise, whether or
not covered by insurance, before or by any court of any Government Entity,
domestic or foreign, or before an arbitrator of any kind.  Seller is not subject
to or in default with respect to any indictment, order, injunction, decree or
award of any court, arbitrator or Governmental Entity primarily related to the
OEU Business.  To the knowledge of Seller, there are no material contingent
liabilities primarily relating to the OEU Business that are likely to be

affecting any of the Purchased Assets which could materially and adversely
affect the OEU Business or the Purchased Assets, and no governmental entity has
served upon Seller any notice claiming any outstanding violation of any
environmental statute, ordinance or regulation or noting the need for any repair
or redemption with respect to the Purchased Assets, requesting data or access,

of conducting the OEU Business.

     3.11 DEFAULTS. Seller is not in default under or with respect to any
judgment, order, writ, injunction or decree of any court or any Governmental
Entity which could materially adversely affect the OEU Business or any of the

knowledge of Seller, by any other Person, or event that, with notice or lapse of
time, or both, would constitute a default under any agreement (including,
without limitation, any of the Transferred Agreements) entered into by Seller as
part of the operations of the OEU Business which could materially and adversely
affect the OEU Business or the Purchased Assets, and no notices of breach
thereof have been received by Seller.

     3.14 COMPLIANCE WITH LAW.  To the knowledge of Seller, Seller's use of the
Purchased Assets and conduct of the OEU Business are in material compliance with
all, and not in material violation of any, and no condition exists that with
notice or lapse of time or both would cause Seller's use of the Purchased Assets
or conduct of the OEU Business not to be in material compliance with or in
material violation of any, applicable federal, state, local, foreign or other
governmental laws or ordinances, or any order, rule or regulation of any
Governmental Entity to which the OEU Business or Purchased Assets are subject

thereof); nor has Seller, to its knowledge, failed to obtain or to adhere to the
requirements of any government license, permit or authorization material to the
ownership of the Purchased Assets or the conduct of the OEU Business.

OEU Business provided to Buyer on December 14, 1999 fairly presents the
financial information contained therein, as of the date thereof, to the extent
material to the OEU Business as a whole, but is not intended to constitute
financial statements prepared in accordance with generally accepted accounting
principles.

     3.16 UNDISCLOSED LIABILITIES.  Except as set forth on the Seller Disclosure
Schedule, to the knowledge of Seller, Seller is not, and will not be as of the
Closing Date, liable for or subject to any material Liabilities primarily

Business, and in accordance with this Agreement, since the date of such balance
sheet and (c) contingent liabilities, to which the last sentence of Section
3.9(a) applies.

all Purchased Assets free and clear of any Lien or any covenant or other
restriction preventing or limiting the right of Seller in the use of any such
Purchased Asset.  Except as set forth on the Seller Disclosure Schedule, no
Purchased Asset is subject to any covenant or other restriction which may
prevent or limit the right of Seller to sell any of the Purchased Assets to
Buyer as contemplated in this Agreement.  All material equipment and other
tangible assets included in the Purchased Assets are in such operating condition
and repair as to permit the conduct of the OEU Business.

     3.18 LICENSES AND AUTHORIZATIONS.  Other than general business licenses
which do not specifically relate to the OEU Business, there are no material
governmental licenses, permits, consents, franchises, certificates of compliance
or other authorizations from, or pending applications to, any Person or
Governmental Entity held by Seller and necessary for the conduct of the OEU
Business at the date hereof.

Seller shall not directly or indirectly (i) develop, host or market to customers

<PAGE>

     5.2  SUPPORT.  Upon signing, Buyer and Seller shall notify in writing all

calls from customers of the OEU Products related to the OEU Products, Seller's
support representatives will inform the callers of Buyer's support telephone
number and will perform a "warm" hand-over of such callers to Buyer's support
representative.  Seller's support representative will place the caller on hold
and dial a telephone number into Buyer's support queue.  When connected to a
Buyer support representative, Seller's support representative will explain the
purpose of the call, will conference in the caller, perform the necessary
introductions and drop off the call; (ii) Buyer's support representatives

Abu Dhabi Company for Onshore Oil Operations and Seller, effective February 27,
1999 and February 15, 1999, respectively, (collectively, the "ADCO CONTRACTS").
Each party shall keep track of the expenses incurred by such party, including
the costs of employees and overhead.  The amounts of such costs shall be paid
quarterly by Seller or when due if sooner.  One half of the amounts incurred by
Seller, Buyer and Torch Energy Advisors, Inc. in connection with the completion
of the ADCO Contracts shall be added to the principal amount of the Note
quarterly.  Seller remains liable for its present obligations related to the OEU
Products pursuant to the Financial Services & Human Resources Software
Implementation Contract between Kuwait Oil Company (K.S.C.) and JMT-Alghanim &
Sons General Trading and Contracting Company, made June 15, 1998.

thereafter, Seller shall allow Buyer to use the term "formerly known as Oracle
Energy Upstream" in reference to the OEU Products and services.

     5.5  PUBLIC ANNOUNCEMENTS. Buyer and Seller shall advise and confer with
each other prior to the issuance of any reports, statements or releases
concerning this Agreement (including the Exhibits hereto) and the transactions
contemplated herein.  Neither Buyer or Seller will make any public disclosure
with respect to the transactions described or contemplated in this Agreement
unless both parties agree on the text and timing of such public disclosure;
provided, however, that nothing contained herein shall prevent either party at
any time from furnishing any information to any Governmental Entity or prevent
Buyer or Seller from issuing any release when it believes in its sole discretion
it is legally required to do so.

     5.6  NO IMPLIED LICENSE. Nothing set forth in this Agreement or the
Exhibits or Schedules hereto or in any other agreement or document delivered or
executed pursuant to this Agreement or any other document or agreement
contemplated hereby or in connection with the

                                       15
<PAGE>

transactions contemplated hereby or thereby shall confer upon Buyer any implied
license to use any Intellectual Property Rights of Seller not specifically
granted, assigned or licensed to Buyer pursuant to this Agreement or such other
documents or agreements.

     5.7  AUDITS.  Seller will, and will cause its officers, employees and
auditors to, cooperate with Buyer and Buyer's auditors in preparing audited
financial statements of the OEU Business for periods prior to the Closing.  Such
cooperation will include providing Buyer and its auditors reasonable access
during business hours to financial information of Seller, and the execution of
customary management letters addressed to Buyer's auditors.

     5.8  BUYER STATUTORY FILINGS.  Seller shall cooperate fully with Buyer in
preparing and filing all information and documents deemed necessary or desirable
by Buyer under any statutes or governmental rules or regulations pertaining to

connection with any filings under the HSR Act.

     5.9  SELLER STATUTORY FILINGS.  Buyer shall cooperate fully with Seller
in preparing and filing all information and documents deemed necessary or
desirable by Seller under any statutes or governmental rules or regulations
pertaining to the transactions contemplated by this Agreement, including but not
limited to the HSR Act.

     5.10  CONSENTS.  Seller shall use its reasonable best efforts to acquire
and deliver to Buyer at the Closing all consents necessary to transfer the
Purchased Assets.  To the extent that the rights of Seller under any Transferred
Agreement, commitment, license, right, lease or other asset to be assigned to
the Buyer hereunder may not be assigned without the consent of another person
which has not been obtained, this Agreement shall not constitute an agreement to
assign the same if an attempted assignment would constitute a breach thereof or
be unlawful.  If any such consent shall not be obtained or if any attempted
assignment would be ineffective or would impair Buyer's rights to the asset in
question so that Buyer would not in effect acquire the benefit of all such
rights, Seller, to the maximum extent permitted by law, shall act after the
Closing as the Buyer's agent in order to obtain for the Buyer the benefits
thereunder and shall cooperate, to the maximum extent permitted by law, with the
Buyer in any other reasonable arrangement designed to provide such benefits to
Buyer.

     5.11  TRADEMARKS.  Following the Closing, Buyer may seek registration of
Trademarks related to the OEU Business.  Seller will, upon Buyer's request,
undertake reasonable efforts to assist Buyer with respect to the registration of
trademarks related to the OEU business so long as such marks do not contain
"Oracle" or any terms which may be confusingly similar to any of Seller's

SECTION 6.  EMPLOYEE MATTERS

     6.1  OFFERS OF EMPLOYMENT. The Buyer Disclosure Schedule attached to this
Agreement sets forth a list of the employees of Seller currently employed in the
OEU Business to whom Buyer intends to offer employment with Buyer after the
Closing Date (the "EMPLOYEES").  The Seller

<PAGE>

Disclosure Schedule includes the names, home addresses, compensation levels and
job titles of all Employees. Buyer has contacted the Employees for the purposes
of making offers of employment with Buyer after the Closing Date and receiving
written acceptances of such employment (in each case contingent on consummation
of the transactions contemplated by this Agreement). Buyer shall hire all
Employees to whom it has made an offer of employment in accordance with this
Section 6.1 and who have accepted such offer prior to Closing. Each such
Employee who is employed by Seller on the Closing Date and who actually
transfers to employment with Buyer after the Closing Date in accordance with the
foregoing is hereafter referred to as a "TRANSFERRED EMPLOYEE". The employment
of the Transferred Employees by Seller shall end at the close of business on the
Closing Date and the employment of the Transferred Employees by Buyer shall
commence at 12:01 a.m. on the day after the Closing Date. Transferred Employees
shall not include any person on a disability leave unless specifically
identified by Buyer on the Buyer Disclosure Schedule.

     6.2  COMPENSATION AND BENEFITS OF TRANSFERRED EMPLOYEES.  Immediately
after Closing, Transferred Employees shall receive salaries from Buyer no less
favorable than salaries received by them prior to the Closing Date from Seller.
The other terms of employment offered to Transferred Employees by Buyer shall be
competitive with market conditions, as determined by Buyer in its reasonable
business judgment.  Transferred Employees shall receive standard Buyer employee
benefits for employees of comparable status.  Coverage for Transferred Employees
under Buyer's benefit plans and programs shall commence as of 12:01 a.m. on the
day after the Closing Date.  Buyer shall give each Transferred Employee credit
for such Transferred Employee's years of most recent continuous service
(including time during approved leaves of absences of less than twenty-six (26)
weeks) with Seller for purposes of determining participation and benefit levels
under all of Buyer's vacation policies.

     6.3  NO RIGHT TO CONTINUED EMPLOYMENT OR BENEFITS.  No provision in this
Agreement shall create any third party beneficiary or other right in any Person
(including any beneficiary or dependent thereof) for any reason, including,
without limitation, in respect of continued employment (or resumed employment)
with Seller or Buyer or in respect of any benefits that may be provided,
directly or indirectly, under any plan or arrangement maintained by Seller or
Buyer. Except as otherwise expressly provided, Buyer is under no obligation to
hire any employee of Seller, provide any Employee with any particular benefits,
or make any payments or provide any benefits to those employees of Seller whom
Buyer chooses not to employ.

     6.4  FICA, EMPLOYMENT TAXES.  Buyer shall be responsible for all FICA,
payroll and employment taxes relating to the Transferred Employees commencing
from the time they become Transferred Employees.

     6.5  SELLER EMPLOYEE BENEFIT PLANS.  Buyer shall not assume or have any
responsibility for any Seller Plans or Commonly Controlled Entity benefit plans
or programs.  Seller shall give all notices and provide insurance coverage, if
any, in connection with this transaction required by the Consolidated Omnibus
Budget Reconciliation Act of 1985 and Health Insurance Portability and
Accountability Act and any other applicable law prior to Closing or in a timely
manner thereafter.  Seller shall indemnify Buyer for any loss or claim Buyer may
incur in connection with the Seller's obligations in the preceding sentence.
This indemnity is exclusive of any other indemnity provided by Seller in this
Agreement with respect to the subject matter of this Section 6.5.

                                       17
<PAGE>

     6.6  WARN.  Seller shall indemnify and hold Buyer harmless from any loss or
claims Buyer may incur due to the termination by Seller of Seller's employees
with respect to, arising under or relating to the Worker Adjustment and
Retraining Notification Act and any other similar state or local "plant-closing"
or severance pay law as a result of the transactions contemplated by this
Agreement.  This indemnity is exclusive of any other indemnity provided in this
Agreement.

     6.7  REIMBURSEMENT RE: DEREK AUSTIN.  Within ten (10) days after each pay
period, Buyer shall reimburse Seller for all the associated costs and expenses
of keeping Derek Austin on Seller's payroll until he is admitted as a temporary
employee under the H-2B classification of 8 CFR Part 214.2(h).  Seller will not
terminate Mr. Austin's employment without Buyer's consent and will not
materially change the compensation or benefits paid to Mr. Austin without
Buyer's prior consent, which will not be unreasonably withheld.  For so long as
Mr. Austin is employed by Seller, Seller shall make the full time services of
Mr. Austin available to Buyer.

     6.8  REIMBURSEMENT RE:  ANIL SRIRAM.  Within ten (10) days after each pay
period, Buyer shall reimburse Seller for all the associated costs and expenses
of keeping Anil Sriram on Seller's payroll until the earlier of (i) eight (8)
months following the Closing Date or (ii) such time when Buyer shall notify
Seller in writing to discontinue retaining Mr. Sriram on Seller's payroll.  For
as long as Mr. Sriram is employed by Seller, Seller shall make the full time
services of Mr. Sriram available to Buyer.

     6.9  SEVERANCE PAYMENTS.  Seller shall transfer to Buyer the severance
payments payable by Seller to employees of Seller currently employed in the OEU
Business who accept employment with Buyer "Accepting Employees" upon single
notice by Buyer of acceptance of employment by Accepting Employees.   The amount
of the severance payment shall be equal to Seller's standard severance package
for each of the Accepting Employees. Buyer shall use such amounts solely for
payment to the respective Accepting Employees as retention bonuses to be paid
within one (1) year of the Closing Date.

     9.4  INDEMNIFICATION PROCEDURE.

          (a) Whenever any Loss shall be asserted against or incurred by a Buyer
Indemnitee or Seller Indemnitee (the "INDEMNIFIED PARTY"), the Indemnified Party
shall give written notice thereof (a "CLAIM") to the Seller or Buyer,
respectively (the "INDEMNIFYING PARTY").  The Indemnified Party shall furnish to
the Indemnifying Party in reasonable detail such information as the Indemnified
Party may have with respect to the Claim (including in any case copies of any
summons, complaint or other pleading which may have been served on it and any
written claim, demand, invoice, billing or other document evidencing or
asserting the same).  The failure to give such notice shall not relieve the
Indemnifying Party of its indemnification obligations under this Agreement.

          (b) If the Claim is based on a claim of a Person that is not a party
to this Agreement, the Indemnifying Party shall, at its expense, undertake the
defense of such Claim with attorneys of its own choosing reasonably satisfactory
to the Indemnified Party.  In the event the Indemnifying Party, within a
reasonable time after receiving notice of a Claim from the Indemnified Party,
fails to defend the Claim, the Indemnified Party may, at the Indemnifying
Party's expense, undertake the defense of the Claim and may compromise or settle
the Claim, all for the account of the Indemnifying Party.  After notice from the
Indemnifying Party to the Indemnified Party of its election to assume the
defense of such Claim, the Indemnifying Party shall not be liable to the
Indemnified Party under this Section 9.4 for any legal expenses subsequently
incurred by the Indemnified Party in connection with the defense thereof, except
for such expenses incurred in connection with cooperation with, or at the
request of, the Indemnifying Party; provided, however, that the Indemnified
Party shall have the right to employ counsel to represent it if, in the
Indemnified Party's reasonable judgment, based upon the advice of counsel, it is
advisable, in light of the separate interests of the Indemnified Party and the
Indemnifying Party, for the Indemnified Party to be represented by separate
counsel, and in that event the reasonable fees and expenses of such separate
counsel shall be paid by the Indemnifying Party.

          (c) The Indemnifying Party shall not, except with the consent of the
Indemnified Party, given in its sole discretion, consent to entry of any
judgment or enter into any settlement.

     10.4  SEVERABILITY. In the event any provision of this Agreement shall be
determined to be invalid or unenforceable under applicable law, all other
provisions of this Agreement shall continue in full force and effect unless such

intent of the parties expressed in this Agreement or unless the invalid or
unenforceable provisions comprise an integral part of, or are inseparable from,
the remainder of this Agreement.  If this Agreement continues in full force and
effect as provided above, the parties shall replace the invalid provision with a
valid provision which corresponds as far as possible to the spirit and purpose
of the invalid provision.

provisions of this Agreement, and the correction of errors and defects in any

Agreement, express or implied, are intended or shall be construed to confer upon
