conditions. Alberta will also ensure the integration of the various rig systems and assist Verdisys in deploying the rig through commissioning and into
commercial operation. Alberta will also provide field operator training on a fee basis to be negotiated.



2. The Project



From the effective date of this agreement until final rig system commissioning and commercialization, ALBERTA will deliver to VERDISYS the equipment and services described in Appendix Aattached hereto (the
Equipment and Services) for VERDISYS operation of An Abrasive Fluid Jet Coiled Tubing Rig System with a minimum working depth of 8,500 with 1.25 coiled tubing, minimum surface pressure of 15,000 psi, a goal of continuous
slurry circulating time of thirty (30) minutes, and a minimum injector speed of 200 feet per minute in and out of the well bore. It is understood that Verdisys will provide ancillary services and support to ALBERTA during the building phase of the
AFJ CT Rig System.



3. PAYMENT TERMS



Verdisys will establish a separate cash account (Construction
Fund) to fund the turnkey project with Alberta. The Construction Fund will be funded according to the dates and times agreed upon between Verdisys and Alberta, per Exhibit B attached hereto (Payment Terms). Verdisys
will advance to $50,000 to Alberta on a reimbursement basis from the Construction Fund for working capital needs of Alberta in executing the turnkey project. Verdisys will replenish the advance based on submitted invoices. Alberta will submit less

4. Budget Overruns



In the event that the $850,000 budget for rig construction is exceeded, the first $100,000 of overruns, if any, are for the
account of Alberta. In the event that additional overruns occur in excess of $950,000, all such overruns, if any, are for the account of Verdisys.



5. Arbitration



| | (a) | All disputes under this Agreement shall be settled by arbitration at such time pursuant to the rules of the American Arbitration Association. Arbitration may be commenced at any
time by any Party hereto giving written notice to the other Party that a dispute has been referred to arbitration under this Section. Each Party shall each appoint one individual as an arbitrator and the two individuals so appointed shall select
another individual to serve as the third and final member of the arbitration panel. Any award rendered by the arbitrators shall be conclusive and binding upon the Parties provided, however, that any such award shall be accompanied by a written
opinion of the arbitrators giving the reasons for the award. This provision for arbitration shall be specifically enforceable by the Parties, and the decision of the arbitrators in accordance herewith shall be final and binding and there shall be no
right to appeal therefrom. Each Party shall pay its own expenses of arbitration and the expenses of the arbitrators shall be equally shared; provided, however, that if in the opinion of the arbitrators any position or claim of a Party or any defense
or objection thereto was unreasonable, the arbitrators may assess, as part of their award, all or any part of the arbitration expenses of the other Party (including reasonable attorneys fees and fees of the arbitrators) against the Party
raising such unreasonable position, claim, defense or objection.

dispute to arbitration, any Party may commence a civil action in a court of appropriate jurisdiction to solve disputes hereunder. Nothing contained in this Section shall prevent the Parties from settling any dispute by mutual agreement at any time.
