                             --------------------

     This Consulting Agreement (the "Agreement") is made effective as of the 1st
day of April, 1999 (the "Effective Date"), between Anthony "Skeeter" Lasuzzo
(the "Consultant") and Indian Oil Company, an Oklahoma corporation (the

     In consideration of the mutual agreements set forth below and other good
and valuable consideration, the mutuality, adequacy, and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

     1.   Engagement.  As of the Effective Date, the Company shall engage the
          ----------
Consultant, and the Consultant shall accept the engagement of the Company, upon
the terms and conditions set forth in this Agreement.  During the term of this
Agreement, the Consultant will perform such duties for the Company as described
herein in accordance with the highest professional standards.  The Consultant
shall perform such duties as required herein for a minimum of twenty (20) full
business days per month.

     2.   Term.  The term of this Agreement shall begin as of the Effective Date
          ----
and shall continue until terminated as provided for in Section 7 below.

     3.   Duties.
          ------

          3.1   Background.  The Company has entered in an Agreement and Plan of
                ----------
Merger (the "Merger Agreement") with Coral Reserves, Inc., Coral Reserves Energy
Corp., and Coral Reserves Group, Ltd. (collectively, the "Coral Group") pursuant
to which the Company and several affiliated limited partnerships of the Coral
Group will merge or otherwise reorganize (the "Reorganization") into a newly-
formed entity ("Coral Public"), whose common stock will be registered with the
Securities and Exchange Commission (the "Public Stock"), so that, upon
consummation of the Reorganization, the Company and such limited partnerships
will cease to exist and the partners of such limited partnerships and the
shareholders of the Company will receive Public Stock.  The number of shares of
Public Stock to be received by the Company's shareholders will be determined
based on engineering reports (the "Reserve Report"), as adjusted as required by
the Merger Agreement, prepared by independent third party engineers setting
forth:

          (i)   The proven oil and gas reserves attributable to the oil and gas
     properties of the Company;

          (ii)  the aggregate present value, determined on the basis  of stated
     pricing assumptions, of the future net income with respect to such oil and
     gas properties, discounted as a stated per annum discount rate of proven
     reserves; and
<PAGE>

          (iii) projections of the annual rate of production, gross income and
     net income with respect to such proven reserves.

          3.2   Duties.  The Consultant is hereby retained and appointed to
                ------
counsel, provide services, and assist the Company with preparing and assembling
the documents necessary for the Reserve Report to be delivered, with the primary
goal being to legitimately demonstrate as high a value as possible for Company's
reserves. The Consultant will assist the independent third party engineers in
all respects regarding the Reserve Report.  In addition, the Consultant will
identify potential wells for the Company to sell, make recommendations regarding
participation elections, and perform such other tasks as may be necessary to
perform the duties required by this Section 3.2.

     4.   Extent of Services.  This Agreement shall not prohibit the Consultant
          ------------------
from engaging in activities other than those required hereunder, whether for
family, recreation, investment, or charity, so long as those activities do not
interfere with the ability of the Consultant to fully carry out his duties,
covenants, and other obligations hereunder and so long as they are not
inconsistent with the interests of the Company or with this Agreement.

     5.   Compensation.  The Consultant shall be entitled to receive $75,000
          ------------
cash (the "Fee") for his services to be performed hereunder; provided, however,
that the Fee may be reduced as provided in Section 8.3 if, for example, this
Agreement is terminated under Section 7.2 or 7.3.  The Fee shall be paid on the
earlier to occur of (i) March 1, 2000, and (ii) the occurrence of an earlier
termination of this Agreement that requires payment of the Fee.  The Consultant
may also be entitled to the additional bonus described in Sections 8.6 and 8.7.

     6.   Duty of Loyalty.  The Consultant recognizes that he owes a duty of
          ---------------
loyalty and good faith to the Company and agrees that, during the term of this
Agreement, he will not in any way, directly or indirectly, by himself or through
any one or more other persons or entities, take advantage of any corporate
opportunity of the Company, engage in any act of self-dealing, sell or willfully
disclose any confidential or proprietary information or trade secrets of the
Company, or have any economic interest in any entity or arrangement which is in
any way competitive with the interests of the Company, without first disclosing
all facts and details relating thereto to the Board of Directors of the Company
in writing and obtaining the prior written approval of the Board of Directors.
Nothing in this Agreement is intended to prevent the Consultant from providing
services to the Coral Group prior to the delivery of the Reserve Report to the
Company so long as the Consultant devotes substantially all of his time and
attention to providing services to the Company as required hereunder.  After the
delivery of the Reserve Report to the Company and prior to the

                                       2
<PAGE>
