AGREEMENT
                                    ---------

     This Agreement is entered into this 4th day of June, 1999, by and between
NEVTAH CAPITAL MANAGEMENT CORPORATION, 4400 PGA Boulevard, Suite 716, Palm Beach
Gardens, Florida 33410 (hereinafter referred to as "NEVTAH"), and PETROLEUM
ASSET MANAGEMENT COMPANY, 204 Point East Drive, Nashville, Tennessee 37216, and
AIR PULSE OIL PUMP, INC., 204 Point Fast Drive, Nashville, Tennessee 37216
(hereinafter collectively referred to as "PAMCO").

                                   WITNESSETH

     WHEREAS, NEVTAH desires to take advantage of investment opportunities that
provide significant potential for return, including projects in the energy and
technology field; and

     WHEREAS, PAMCO has developed a state-of-the-art pumping technology that
will provide particular economic benefit to the operation of "stripper" oil
wells (wells which produce less than ten barrels of oil per day); and

     WHEREAS, the PAMCO technology includes a downhole pumping unit and an
aboveground computer controller, all of which is referred to herein as the
"Technology; and

     WHEREAS, NEVTAH and PAMCO desire to combine their efforts to exploit the
Technology in the oil industry through the acquisition of existing stripper well
production (the "Production") and conversion of the Production to the
Technology; and

     WHEREAS, NEVTAH is capable of providing the capital, necessary to acquire
the Production and PAMCO is capable of finding the Production and installing and
operating the Technology;

     NOW, THEREFORE, for and in consideration of the covenants contained herein,
the parties agree as follows:

     1. Prior Agreement: Initial Advances. A prior agreement was entered into
between the parties in March of 1998 (the "Prior Agreement"). PAMCO acknowledges
receipt of One Hundred Thousand Dollars (100,000) under the terms of the Prior
Agreement (the "Initial Advances"). PAMCO further agrees that upon execution of
this Agreement NEVTAH is under no obligation to make additional capital
contributions under the Prior Agreement. PAMCO further acknowledges that the
Initial Advances will be added to and will be considered part of the convertible
debenture to NEVTAH under the Production data phase under Section 2 of this
Agreement.

     2. Collection of Production Data. As a preliminary step to funding a
large-scale acquisition program, NEVTAH agrees to loan Two Hundred Thousand
Dollars, ($200,000) for PAMCO to use in-acquiring leases and stripper wells in
Oklahoma, Texas, and/or Kentucky and installing the Technology on as many as
twenty (20) wells (including operating capital). The payments by NEVTAH to PAMCO
will be made Fifty Thousand Dollars ($50,000) on or before June 12, 1998; One
Hundred Thousand Dollars ($100,000) on or before June 30, 1998; and Fifty
Thousand Dollars ($50,000) on or before July 30, 1998. This loan to PAMCO will
be structured as a convertible debenture to NEVTAH, payable in full in one (1)
year and bearing interest at five percent (5%) simple interest per annum. NEVTAH
will have the right, at any time during the

first year, to convert the full amount of the debenture to common stock in PAMCO
at a conversion rate of the lesser of Fifty-Five Dollars and Fifty Six Cents
($55.56) per share or the latest price of PAMCO share sales. Full conversion at
current pricing would result in 5,399.57 shares being issued to NEVTAH on
conversion, which will convey not less than ten percent (10%) of total issued
stock in PAMCO at the date of this Agreement (allowing for ESOP stock and
current option agreements). The conversion rights of NEVTAH may not be diluted
by the issuance of any additional securities by PAMCO without first giving
NEVTAH the right of first refusal to acquire any securities proposed to be
issued by PAMCO. The right of NEVTAH to convert this debenture to common stock
must be exercised in writing no later than one (1) year after the date of this
Agreement. Under the right of first refusal described in this Section, PAMCO
will provide, written notice to NEVTAH of any proposed issuance and/or sale of
securities, and NEVTAH will have ten (10) days to accept Or reject the right of
first refusal and an additional thirty (30) days to make payment for the
securities if the right is accepted.

     The wells acquired and the Technology acquired with the proceeds of the
debenture will be operated for a period of up to 90 days to allow NEVTAH and
PAMCO to review the field operations and Production data for these wells. At
such time as meaningful data is available, but in no event later than 60 days
after conversion of the acquired Production to the Technology, PAMCO will
provide NEVTAH a written report and accounting of funds used and data collected
in order to establish a budget for future operations. If NEVTAH is not satisfied
with the Production data collected, NEVTAH will have the option of terminating
this Agreement. This election must be made by NEVTAH in writing to PAMCO within
ten (10) days after receipt by NEVTAH of the report of operations of the
acquired wells provided by PAMCO.

     3. Capital Contributions by NEVTAH. Unless this Agreement is terminated by
NEVTAH upon completion of the operations described in Section 2, NEVTAH agrees
to provide the capital necessary for PAMCO to acquire additional Production in
amounts sufficient to satisfy the installation and operational capabilities of
PAMCO over the period of this Agreement. The initial capital funding commitment
of NEVTAH in this regard is described on Exhibit A attached hereto. NEVTAH
agrees to make additional minimum capital contributions, in addition to those
listed on Exhibit A, as established in Section 10 herein and as described on
Exhibit B attached hereto.

     4. Joint Venture Entity. At such time as NEVTAH has met the funding
schedule described on Exhibit A, NEVTAH and PAMCO will create a joint venture
entity called NEVCO LLC ("NEVCO"), a Tennessee limited liability company
("LLC"). NEVTAH and PAMCO will each own fifty percent (50%) of the Financial
Interest and Governance Interest, and will be the only members, of NEVCO. NEVCO
will be a board-managed LLC and NEVTAH and PAMCO will each select two (2)
members to sit on the Board of Governors, which will be limited to no more than
five (5) Governors. A fifth member of the Board will be added only on the joint
approval and agreement of NEVTAH and PAMCO. The officers of NEVCO will be
selected by the Board at the time of formation.

     To minimize total operating costs, all administrative functions and
management overhead required for NEVCO will be carried out by PAMCO and carried
as part of the operating overhead of PAMCO. Payment of such overhead will be
included in the operating budget to be prepared by PAMCO and submitted to NEVTAH
for approval pursuant to Section 9 of this Agreement.

     5. Purpose of NEVCO. The purpose of NEVCO will be to provide a vehicle for
the combined efforts of NEVTAH and PAMCO in acquiring the Production and
conversion of the Production to the Technology. All Production acquired under
this Agreement will De transferred to and held in the name of NEVCO. NEVCO will
also receive an exclusive license to the Technology of PAMCO under the
provisions of Section 7 herein.

     6. Obligations of PAMCO. PAMCO agrees to locate and select suitable
stripper well leases for acquisition by NEVCO as part of the Production. PAMCO
further agrees to install and operate the Technology on the Production and to
use reasonable efforts to optimize Production from each well acquired by NEVCO.
PAMCO will also monitor the operations of the Production and provide a written
report to NEVTAH no less frequently than monthly.

     As part of PAMCO's duties in locating and selection suitable leases for
acquisition as part of the Production, PAMCO will provide a written report to
NEVTAH which will include an acquisition budget for a proposed lease acquisition
and a summary of all information relating to the lease and its history of
operation. This budget will include operating capital estimated to be required
by PAMCO to fully support the planned operations. The Board of Governors of
NEVTAH will then follow the procedure outlined in Section 8 herein.

     7. Exclusive License of Technology. Upon completion of payments by NEVTAH
under Exhibit A, PAMCO agrees to provide an exclusive license to NEVCO of all
rights to the Technology (the "Exclusive License"), subject to timely completion
of obligations of NEVTAH under this Agreement. Until completion of payments by
NEVTAH under Exhibit B, PAMCO will retain the right to utilize the Technology
under the terms of this Agreement, in trust for NEVCO. As long as this Agreement
is in effect and NEVTAH is in compliance with the terms of this Agreement, PAMCO
agrees that it may not license the Technology to any other company.

     The Exclusive License described in this Section will terminate in the event
that NEVTAH does not provide on-going capital to NEVCO in a timely manner in
Exhibit B established in Section 10. In addition, NEVCO will not have the right
to sub-license, hypothecate, or transfer any rights in the Exclusive License
granted herein to any third party without the express written consent of PAMCO.

     8. Acquisition of Production. The acquisition of Production by PAMCO under
this Agreement will initially involve only the use of funds contributed by
NEVTAH as described In Section 2 and on Exhibit A. Beginning January 1, 1999,
however, NEVTAH agrees that it will continue to provide capital to NEVCO as
needed by NEVCO under the schedule shown on Exhibit B. As producing oil well
leases are evaluated and selected by PAMCO, from time to time, for acquisition
with funds provided by NEVTAH, PAMCO will provide a written report to NEVTAH (or
NEVCO, as appropriate) including an acquisition and conversion budget and a
summary of basic information concerning the history of the target wells (the
"Target Wells"). The report by PAMCO will also provide a timetable for
acquisition and conversion of the Target Wells, as well as the terms proposed
for evaluation and/or acquisition of the Target Wells. The report will state
whether funds will be required to be advanced for evaluation of the lease,
whether the lease will be initially acquired by (and funds required for) an
option of the lease pending acquisition, and the timetable for the payment for
such advances, options, or purchase. The budget will include an operating
capital component for PAMCO as described in Section 9 herein.

<PAGE>


Agreement between NEVTAH and PAMCO
Page 4


     If neither NEVCO or NEVTAH objects in writing to the acquisition of the
Target Wells within five (5) days after receipt of the report from PAMCO, PAMCO
will proceed with the acquisition, conversion, and operation of the Target
Wells, provided that if PAMCO discovers information during this process that
indicates acquisition should not be completed, they will so notify NEVTAH,
and/or NEVCO. If either NEVCO or NEVTAH objects to acquisition of the Target
Wells, PAMCO or any other entity may acquire the Target Wells for its own
account or for the account of others (but not using funds provided under this
Agreement), subject to the sharing of revenue established in Section 9 of this
Agreement.

     The requirement of PAMCO to follow the procedures outlined in this Section
will terminate at such time, if any, as this Agreement terminates.

     9. Sales or Joint Ventures: PAMCO Operating Capital: Revenue Sharing Prior
to Merger. PAMCO will have the right to sell the Technology either directly
(prior to the formation of NEVCO), or through NEVCO, at prices established
according to the formula described below. PAMCO will also have the right to
enter into joint venture arrangements with, other companies who are not a party
to this Agreement, for the acquisition and/or installation of the Technology in
the oil and gas industry, provided that PAMCO agrees that its primary focus
under this Agreement will be acquisition of Production under this Agreement and
that its obligations under this Agreement to NEVTAH and NEVCO are a priority. In
addition, any revenues received by PAMCO from a joint venture with an
independent third party will go to the benefit of both PAMCO and NEVTAH under
this Agreement (or NEVCO if formed at that time) and no such joint venture will
be undertaken by PAMCO that will prevent or hinder PAMCO from carrying out its
obligations to NEVTAH and NEVCO under this Agreement. All revenues received by
PAMCO, or NEVCO, from these activities will be received in trust by PAMCO or
NEVCO for distribution of profits on a 50-50 basis with NEVTAH, subject only to
the operating capital needs of PAMCO described below.

     NEVTAH acknowledges that PAMCO does not currently have sufficient operating
capital to support its obligations under this AgreemenE and that a special
allocation of available funds will be required to assure that PAMCO receives and
maintains sufficient capital to fund its operating overhead through the calendar
year 1999. NEVTAH and PAMCO agree that the pricing of the Technology through the
Production data phase described in Section 2. and using funds described on
Exhibits A and B, will be actual costs to PAMCO plus an overhead component to
PAMCO. PAMCO agrees to provide an overhead budget to be approved by NEVTAH to
cover the period from the date of execution of this Agreement through the
calendar year 1999. Any net profits received from sales to third parties, or net
profits received from joint ventures with third parties, will be applied to and
will reduce the overhead component on the Technology sold to PAMCO or NEVCO to
install on Production acquired by funds provided by NEVTAH under this Agreement.

     It is the intent of this Agreement that all revenues received by PAMCO or
NEVCO during the term of this Agreement be received for the purposes described
in this Agreement and that any profits remaining be held and/or distributed to
the benefit of PAMCO and NEVTAH on a 50-50 basis.

     10. Minimum Contribution of NEVTAH; Termination of Exclusive License. In
addition to the capital contributions required to be provided by NEVTAH under
Exhibit A, NEVTAH agrees to contribute additional capital as set out on Exhibit
B attached hereto. In the event NEVTAH has satisfied the payment schedule under
Exhibit A but fails to satisfy the capital contribution level schedule under
Exhibit B, the Exclusive License and this Agreement will terminate.

     11. Merger. Upon completion of payments by NEVTAH as established on Exhibit
A and Exhibit B to this Agreement, it is agreed that PAMCO and NEVCO will merge
operations, either through a statutory or contractual merger arrangement,
provided that voting rights in the surviving entity will remain 50% with PAMCO
and 50% with NEVTAH. The exact form of the merger and the vehicle for bringing
additional capital into the merged entity will be determined by mutual agreement
of PAMCO and NEVTAH.

     12. Time of the Essence; Force Majeure. NEVTAH and PAMCO agree that the
time is of the essence regarding obligations under this Agreement. The inability
of NEVTAH to satisfy the funding deadlines established on Exhibit A or Exhibit B
in a timely manner will be considered a default under the terms of this
Agreement, and PAMCO will then have the right to terminate the Agreement under
Section 13. PAMCO and NEVTAH also agree, however, that notwithstanding the
preceding language, if the spot price of crude oil, for the weight and grade of
crude produced in the Tulsa, Oklahoma, area drops below Twelve Dollars ($12) per
barrel, the obligations of NEVTAH under this Agreement will be delayed until
such time as the price of oil recovers above the Twelve Dollar ($12) per barrel
level. It is also agreed that if due to delays based on the price of oil, or for
any other reason, PAMCO does not have sufficient operating capital to carry out
its obligations under this Agreement, PAMCO will not for this reason be in
default under this Agreement and NEVTAH will cooperate with PAMCO in addressing
and solving any operating capital problems.

     13. Restriction on Sale of Company. PAMCO agrees that, for so long as
NEVTAH is in compliance with the timetable for funding under the terms of this
Agreement, PAMCO will not contract to sell or sell PAMCO as a company to any
third party.

     14. Termination by Agreement. NEVTAH will have the right to voluntarily
terminate this Agreement at any time, upon thirty (30) days written notice to
PAMCO. The rights which NEVCO will retain depends upon the timing of such
termination. If such termination occurs at the end of the collection of
Production data phase of this Agreement (Section 2), NEVCO will have no rights
in any future activities of PAMCO. If this Agreement is terminated by NEVTAH
prior to the completion of capital contribution obligations of NEVTAH under
Exhibit A, NEVCO will retain rights to all Production acquired, or in the
process of being acquired, with funds available to NEVCO at the time of
termination.

     In the event that NEVTAH voluntarily terminates this Agreement after all
obligations set out on Exhibit A have been satisfied, NEVCO will retain
ownership of all Production acquired through funds contributed to the date of
termination. NEVTAH will also have a non-exclusive right to purchase the
Technology systems for its own account.

     Upon voluntary termination by NEVTAH, or the default of NEVTAH in the
minimum payment provisions or under any other provision set out in this
Agreement, the rights of NEVTAH to the Exclusive License will terminate. Upon
default of NEVTAH in the timely payment of funds required under any section of
this Agreement, PAMCO may terminate this Agreement on written notice to NEVTAH.

     15. Scope of Technology. The terms "Technology" as used in this Agreement
will include both the current state of the Technology at the time of execution
of this Agreement and any future developments or improvements of the Technology
developed through the efforts of PAMCO or NEVCO. Any new developments in the
Technology or improvements to existing Technology will remain the property of
PAMCO, but will be included in and subject to the Exclusive License established
