EXCLUSIVE MARKETING AND TECHNOLOGY AGREEMENT BETWEEN RELIABLE POWER SYSTEMS INC.
AND PERFECT POWER SYSTEMS INC.

4-10-01

Reliable Power Systems Proposal for the Exclusive sales and marketing of the
Seamless Power Machine.

Reliable Power Systems, Inc., ("RPSI"), desires to enter into an exclusive
relationship with Perfect Power Systems, Inc. ("Perfect Power"), to sell and
market the Patented Seamless Power Machine, (SPM), patent numbers, 6204572 and
6020657. The exclusive basis for this agreement covers all sales channels and
OEM potentials. This understanding also is based with the agreement that Perfect
Power or On-Line Power will not attempt to sell the SPM under any other Logo's
or product names. RPSI understands the Patented nature of this product and will
sell it with the full commitment to protect Perfect Power's patent. The
commitment from RPSI to pre-purchase SPM's from Perfect Power is based on the
exclusivity of the SPM to RPSI and if violated by Perfect Power will be
considered an immediate breach of this agreement. Perfect Power's current
projects are listed below. In the case where RPSI receives the Purchase Order on
named projects, both companies will split the gross profit minus commissions,
taxes or freight, as defined later in this contract. The projects known to RPSI
are as follows: Dana Corp, Eastern Missouri Location, Intel's San Francisco four
module parallel project, which was generated by Mike Warner, Above Net single
module system designed by Mike Mossman of CCG Inc. Invinsis Show room, single
module, and other projects that were quoted within the last ninety days by
Perfect Power and submitted in writing to RPSI within 15 days of signing this
agreement.

In the event Perfect Power refers a customer for the SPM to RPSI that produces a
sale, the actual purchase order from the customer will be used to determine the
gross profit over the purchase price from Perfect Power to RPSI. The gross
profit minus any taxes and commissions including freight will be divided between
the two companies, with 60 percent going to RPSI and 40 percent to Perfect
Power.

This contract shall remain in effect for a minimum of 24 months, and can be
extended by mutual agreement between RPSI and Perfect Power.

The SPM will be built to the specifications as defined by attachment A of this
agreement. The cost of the SPM between RPSI from Perfect Power is firm for the
contract period. RPSI desires to sell the complete product line of SPM's with
pricing for all available models currently under production. The price per unit
will be exclusive of freight, which will be handled directly by RPSI.

                                      -2-


The price per unit will be determined based upon the specifications of each
unit. RPSI agrees that the total purchase price for the full 65 unit commitment
will be at a minimum of at least $24,000,000.

The first order for the initial five units will be produced by Perfect Power
within twenty two weeks from receipt of approved drawings. The second purchase
release will be for units 6 through 25, with the third release being for units
26 through 46, with the final release for units 47 through 65. This release
schedule will allow for the full 65 unit commitment to be produced and shipped
within the twenty four month contract period.

The payment terms will be per the standard terms for Perfect Power as defined by
attachment B with this contract. This agreement should include the units from
500 kva though 1250 kva. Pricing for the 500 and 750 kva units will be
negotiated as a separate attachment to this contract. When other unit sizes
become available during the contract period they will be offered to RPSI based
on the existing pricing model of cost per kva. This is with the understanding
that the cost per kva goes down with units of larger sizes.

The commitment to pre-purchase SPM units is based on timely manufacturing
production cycles, (typically 18-22 weeks after release of an order by RPSI,
including the payment terms as defined in this agreement to Perfect Power), firm
delivery dates, and with the final testing preformed by authorized RPSI
personal. In the event a unit fails to meet its specifications, then Perfect
Power will correct the deficiency within a reasonable time frame, not to exceed
three weeks, or that unit can be declared unacceptable and removed form the pre
purchased agreement commitment.

The first commitment of products from Perfect Power for RPSI will be for the
1250 kva units with standard enclosure, as shown in the current SPM literature
(The shuttle design). It will include all monitoring options, including color
display with touch screen, RS 232, 422 and 485 communication interface. The
SPM's will be provided with the input, output and by-pass breakers. RPSI will
not accept any units built as prototypes or Alpha or Beta units currently in
Perfect Powers inventory. The first five units will be built and readied for
approval and acceptance by RPSI personnel, when completed and approved the
second order will be released, and the approval and released cycle will continue
until all 65 units are completed and accepted. The actual delivery schedule is
defined later in this contract. Additional units may be required in excess of
the original units and will be released per a rolling forecast that will be
updated at least twice per month. The delivery of the additional units will be
based upon 18-20 weeks from order release to Perfect Power.

                                      -3-


Perfect Power will provide to RPSI a service commitment with OEM pricing that
will allow both companies to receive revenues. The service pricing will be
compared to other Battery-Less Systems for price comparison and will be
competitive. Perfect Power will additionally guarantee on site service within
the industry standards of timely performance, typically phone response within
two hour of an incoming service call and on site within one day, warranty
service and the stocking of all necessary spare parts to insure fast and
accurate on site repairs.

All service personal must be trained on the SPM and be provided with complete
service manuals and wiring diagrams. Copies of this information will be provided
to RPSI as part of this agreement. The pricing for the service offer must be
approved by RPSI before the first systems are put into production and the
initial payment is made to Perfect Power.

In the event that Perfect Power fails to respond to a customer service problem
in either a timely manor, not to exceed sixty days, or fails to adequately
repair the unit within the sixty day time period, or the unit cannot be
repaired, Perfect Power will replace the defective components or the entire
unit, if necessary, and loan the customer if desired a back up generator. RPSI
will return at its cost the defective parts to Perfect Power at its factory, and
Perfect Power aggress to send the replacement part to the customer site at its
costs.

RPSI Systems will produce a Marketing plan that will offer to both companies the
fastest and broadest based attack for the market potential of the SPM product
line. This plan will be sent to Perfect Power as part of this total offering
from PPSI. The marketing plan includes direct advertising in the major market
target areas such as newspaper ads, specialize ads in the trade journals, direct
market mailers for the Industrial, Hospital, Data, Telecom, and Utility areas.
The market plan will immediately push sales in the California and other
electrical vulnerable markets. This plan will include packaged solutions to the
quality power market that will cover the broadest possible customer base.
Reliable Power is currently contracting with both a Web Site designer and an
advertising agency to insure a professional advertising campaign.

RPSI and Perfect Power as part of this agreement mutually agree not to hire
directly or indirectly through third parties, current employees or from either
company, or employees that choose to leave employment of either company or are
terminated for cause by either company. Should an employee obtain a written
release form this contractual clause; both companies must agree in writing that
an individual employee is exempt from this condition.

RPSI also desires to include other On-Line Power products currently listed in
the OLP customer catalog. RPSI is requesting On-Line Power to provide a separate
pricing discount structure for the complete OLP product offering. RPSI would
like to private label this offering as to insure no potential channel conflict
with your current sales force.

This agreement is the only contract between RPSI and Perfect Power, and will be
controlled by Colorado law and both venue and jurisprudence shall be in Denver
Colorado. In the event either party pursues a legal remedy in order to settle
any disputes relating to this contract, the prevailing party shall be awarded
costs, including without limitation, attorney's fees as deemed reasonable by the
court.

We look forward to working with you in this exciting relationship and getting
this agreement off to a mutual beneficial result.

repairing at the Seller's factory or on the job site at the Seller's sole
option. Any product, part or parts which have been returned to the Seller and
which are defective or do not conform to such specifications, drawings or other

unauthorized replacement parts, or from any misapplication of the item or for
damage due to an accident, abuse or an Act of God.

performed or subcontracted by the Buyer will not be considered as a liability by
the Seller.

         The Seller's obligations under this warranty are conditioned upon
timely receipt of all payments in strict accordance with payment terms, time
being of the essence in this regard. During the time while the Seller has not
received any amount overdue, the Seller shall have no obligation under this
warranty. The expiration date of the warranty shall not be extended upon payment
of the overdue amount.

         This warranty may be modified only in writing, signed by an officer of

litigation and tenders to the extent of the Seller's ability to do so, the

articles ordered shall not be made without consent of the Seller in writing.

petition for adjudication of such insolvency or extension, however termed, of
the obligations of the Buyer or the Seller, of if either the Buyer or the Seller

              withstanding any correspondence from the Buyer referencing
              contrary information, then only the Seller's specifications and/or
              drawings for such model shall be applicable to the articles
              furnished under such order.

              writing by the Buyer and the Seller prior to the date hereof shall
              be applicable to the products furnished under such order and no

be required before actual shipment to the Buyer can be made. At the end of the
30-day period, an extra charge of 3 percent per month will begin, covering the
cost of storage, insurance and the use of capital. If the product is non-stock
item, the Seller would require 30% with initial purchase order & Seller will
