      WHEREAS, the Company desires, in connection with the services to be
rendered by the Optionee pursuant to that certain Distribution Agreement between
the parties dated August ___ 1999, to provide the Optionee with an opportunity
to acquire Common Stock, par value $.01 per share ("Common Stock"), of the
Company on favorable terms and thereby increase its proprietary interest in the

      NOW, THEREFORE, in consideration of the premises, the mutual covenants
herein set forth and other good and valuable consideration, the Company and the
optionee hereby agree as follows:

      1. Confirmation of Grant of Options. Pursuant to a determination by the

the Company, subject to the terms of this Agreement, and the performance by
Optionee of Optionee's obligations, hereby confirms that the Optionee has been
granted the following Stock Options effective August ____, 1999 as a matter of
separate inducement and agreement, and in addition to and not in lieu of other

shares (the "Shares") of Common Stock of the Company. Authorized shares are
currently 100,000,000 shares. On any reorganization/sale/change of control,
options will continue in effect as long as IRD meets its designated sales
levels. Any forward or reverse stock split adjustment or stock dividend will be
reflected in the number of stock options and price available to IRD. Other stock
options or issuance of present authorized shares by UNRG will not affect the
share & available to IRD.

      UNRG shall have the right at any time to increase its outstanding shares
without penalty for the purpose of securing additional financing, the exercise
of outstanding stock options or effecting acquisition(s). However, if at any
time prior to the exercise of options which have become vested hereunder, UNRG
shall issue more than 5,000,000 additional shares for any other purpose for a
cash consideration of less than the average exercise price of the options
granted hereunder, then the amount of options granted hereunder shall increase
by 1,000,000 shares. The terms of such additional options, manner of exercise,
etc. shall be the same as options (2), (3), and (4) granted hereunder.

      2. Vesting of Options. The Options shall vest with respect to

            (a) 750,000 shares on the date of the execution of this agreement

amount of $5 million.

            (b) 750,000 shares upon IRD attaining an additional $5 million in
sales ($10 million aggregate)

                                       1

            (d) 750,000 shares upon IRD attaining an additional $5 million in
sales ($20 million aggregate)

      Sales for purposes of this agreement shall be defined as the dollar amount
IRD pays UNRG on invoices received pursuant to the Distribution Agreement.

      3. Purchase Price. The purchase price of the shares of Common Stock
covered by this Option is fifty percent of the closing asked price on the day
following the date IRD makes payment to UNRG which payment attains the sales
amounts set forth in Section 2, except for the first option which will be at
$1.50 per share.

after the date of vesting as and to the extent vested in accordance with Section
2.

            (b) The Option may be exercised in integral multiples of 50,000
shares for all options remaining hereunder subject to the Option by notice and
payment to the Company as provided in Sections 11 and 16 hereof, except for the
first option which must be exercised in full.

      5. Term of Option.

            (a) The term of each Option shall be for a period of six (6) months

or any other rights of a stockholder with respect to any shares of Common Stock
until same have been issued to him (as evidenced by the appropriate entry on the
books of the duly authorized transfer agent of the Company) provided that the
date of issuance shall not be earlier than the Closing Date (as hereinafter

purchases of such shares upon exercise of the Option.

      6. Non-transferability of Option. The Option shall not be transferable.

      7. Exercise upon Cessation of Distribution Agreement.

                  (a) If the Optionee ceases to serve as a distributor of the
Company or any affiliate or subsidiary thereof by reason of its termination for
cause, as determined in good faith by the Board of Directors of the Company, or

                           JOINT MARKETING AGREEMENT

      This Joint Marketing Agreement is made between Sii CHEMTECH, a business
unit of SMITH INTERNATIONAL, INC., a Delaware corporation ("CHEMTECH"), with its
principal place of business at 5750 LA Highway 90 East, Broussard, Louisiana
70518 and UNITED ENERGY CORPORATION, a Nevada corporation ("UNRG"), with its
principal place of business at 600 Meadowlands Parkway #20, Secaucus, NJ 07094,
and becomes effective on the 1st day of March, 2000 ("Effective Date").

                                    RECITALS

      UNRG desires to obtain sales of the oil and gas well production
enhancement products which it manufactures and which are more fully described in
this Agreement.

      UNRG also has various oil and gas industry contacts and has received
inquiries leading to industry oil servicing projects.

      CHEMTECH represents that it has experience and expertise in the servicing
of oil and gas wells and related equipment such as pipelines and flowlines, and
also sells various chemical treatment products to the oil and gas industry; and

      The parties wish to form a joint marketing agreement on the terms set out
below providing for the sales of their respective products and for compensation
to UNRG for its oil servicing introductions and to CHEMTECH for its marketing
and servicing activities in connection with such venture.

      In consideration of the foregoing and the mutual promises contained
herein, the parties agree as follows:

      1. PLAN AND PURPOSE:

      The parties anticipate that from time to time UNRG will develop projects
in the oil and gas industry which involve the use of UNRG's KH-30 paraffin
dispersant and other oil field chemical treatment programs. CHEMTECH is in the
business of providing oil field services and, in particular, chemical treatment
programs. The parties wish to structure an arrangement which will make best use
of the capabilities and products of each to their mutual benefit. Each of the
parties expects to provide chemical treatment products to this marketing
arrangement for use and/or resale. UNRG is to receive a fee for projects it
develops for the arrangement and CHEMTECH will receive a servicing fee for that
portion of the project which involves providing a service all as more fully set
out below. As used in this Agreement, "Products" mean all items of both parties
separately listed in APPENDIX A. From time to time, the parties may add or
delete individual items from the list.

      2. RELATIONSHIP OF THE PARTIES:

a. This Agreement shall not be construed as creating any partnership, joint
venture, association or other entity. It is the intent of the parties that the
relationship is solely that of parties with contractual commitments to one
another as expressly set forth in this Agreement; that their rights and
obligations with respect to one another will be solely those expressed in this
Agreement; that neither party shall be the agent of the other for any purpose
under this Agreement; and that the liabilities and obligations of the parties
incurred in connection with this Agreement shall be separate.

The joint marketing arrangement will be specifica1ly limited to the products
listed on Appendix A and to the oil servicing contacts listed on Appendix B and
will be in addition to the other activities of each of the parties.

c. This Joint Marketing Agreement shall be non-exclusive.

d. The primary marketing and assembling of project proposals ("Proposals") to
the oil servicing contacts listed on Appendix B (collectively "Customers") of
the Products and services to be offered by the parties pursuant to this
Agreement shall be completed with CHEMTECH personnel and with UNRG personnel.
Either party shall have the right to initiate the drafting of any Proposals, but
any such Proposals mentioning the involvement of the other party or proprietary
technology or information of the other party shall be approved in writing by
such other party prior to the time that the Proposal is submitted to the
Customer.

      3. SALES PURSUANT TO JOINT MARKETING AGREEMENT:

      As stated above, UNRG is to receive a fee for projects it develops for the
arrangement and CHEMTECH will receive a servicing fee for that portion of the
project which involves providing a service. The parties agree that the
compensation set forth in APPENDIX C will apply to any sales pursuant to this
Joint Marketing Agreement.

      4. DURATION AND TERMINATION:

a. Subject to Paragraph 4.b. below, this Agreement shall expire on March 1,
2003. Renewal may be only by a writing signed by both parties. Either party may
cancel this Agreement at any time, without liability and without prejudice to
any other right or claim arising under this Agreement, if the other party
materially breaches this Agreement. Material breaches shall include, but not be
limited to:

      1. Failure of the joint marketing arrangement to make timely payment for
Products delivered or services rendered;

<PAGE>   3

      2. Making an assignment in favor of creditors, voluntarily filing in
bankruptcy, becoming insolvent or failing to dispel reasonable questions

      3. Failure of the joint marketing arrangement to timely exploit a contract
opportunity presented by a party.

      4. Failure by the joint marketing arrangement to pay any service fee or

notice of that party's breach, and the party receiving the notice shall have
thirty (30) days to correct the breach. If it fails to correct the breach within
thirty (30) days, this Agreement may then be terminated.

      b. The term of this Agreement shall automatically be extended for such
period of time as may be required to perform or complete any projects or
contracts entered into or undertaken prior to the expiration of such term
("Unfinished Projects"). Within thirty (30) days prior to the expiration of this
Agreement, if either party believes that it will be necessary for the Agreement
to be extended to permit the performance or completion of any Unfinished
Projects, such party shall give written notice thereof to the other party
specifying the Unfinished Projects, the obligations thereunder that remain to be
completed, and an estimate of the amount of time required for such completion.
Following such notice, the term of the Agreement shall be extended with respect
to the Unfinished Project(s) identified therein to the extent necessary to
complete the remaining unsatisfied obligations within the estimated time frame
specified in such notice, unless within ten (10) days after receipt of such
notice the recipient sends a written response to the other party noting any
exceptions that it may have to the scope or term of the Unfinished Project. Any
resulting disagreement between the parties regarding the extension of the Term
pursuant to this Paragraph 4.b. shall be resolved in accordance with Paragraph
15 below.

      15. MEDIATION/ARBITRATION:

      a. At such time as the representative of either party determines that a

chief executive officers of each party shall have their first meeting at a
mutually acceptable location within five (5) days from the date of such notice

the dispute that was submitted to mediation has not been resolved, either party

"Rules") of the American Arbitration Association (the "AAA") by sending written
notice of the initiation of such arbitration to AAA in accordance with the
Rules, and contemporaneously sending a copy of such notice to the other party.
