is attached as Exhibit A, which will be maintained, managed and operated by VDYS;



WHEREAS, ADS plans to fund the development and construction of the AFJ Rig for U.S. $1.2 million and VDYS shall build, maintain and operate the AFJ Rig for the benefit of the Parties subject to the terms and conditions hereunder;



WHEREAS, VDYS is knowledgeable and experienced in the development and
operation of drill rigs similar to the AFJ Rig; and



WHEREAS, the purpose of
this Agreement is to set forth the responsibilities of the Parties;



THEREFORE,
for good and valuable consideration, the Parties agree as follows:



1. Term
of Agreement.



1.0 The Parties hereby agree that the term of this
Agreement shall terminate on the date that is ten years from the commissioning of the AFJ Rig.



1.2 Effective upon delivery of the Purchase Price, ADS shall hold the title to the AFJ Rig, subject to the rights of VDYS under this Agreement. ADS shall have the right to enter into a written security agreement that
would allow a lien to be placed on the AFJ Rig without the written prior consent of VDYS. ADS covenants and agrees that (i) the terms of such security agreement shall not place any material restrictions on the ability of VDYS to perform its
obligations under this Agreement or to otherwise utilize or deploy the AFJ Rig, (ii) the AFJ Rig shall not be used by ADS as collateral to support one or more obligations, the principal of which would exceed in the aggregate $1 million, and (iii)
ADS shall perform all obligations under any such security agreement (and any loan agreement, note or similar document) and there shall be no default, event of default or breach by ADS under the terms of such security agreement.



1.3 Subject to the rights of VDYS under this Agreement and the VDYS Licensing Agreement with
Alberta Energy Holdings (AEH), VDYS hereby grants ADS a non-exclusive sub-license to use its patented abrasive fluid jetting drill technology for the

sub-license shall be limited to the operation of the specific AFJ Rig funded by this Agreement and shall remain in effect until the date that is 10 years from the Effective Date of this Agreement. As a condition to ADS obligations under this
Agreement, AEH shall execute the consent to the sub-license by VDYS of the abrasive fluid jetting drill technology to ADS pursuant to this Section 1.3 in the form attached hereto as Exhibit B.



1.4 The Effective Date of the Agreement shall be the date of receipt of the wire transfer

2. Funding and Building Obligations.



2.1 ADS agrees to pay to VDYS the amount of U.S. $1.2 million (the Purchase Price) in cash by wire transfer for the development and construction of the AFJ
Rig and VDYS agrees to use commercially reasonable efforts to timely plan, manage and complete the building of the AFJ Rig according to the design and description attached as Exhibit A. The Purchase Price shall be held in a separate account
specifically designated as ADS funds advanced for the purchase of one AFJ Rig. VDYS shall disburse amounts from the ADS funds account as needed for the construction of the AFJ Rig provided that not less than 70% of the funds shall be paid from the
segregated ADS funds account directly to AFJ Rig suppliers, contractors and service providers related to the construction of the rig.



2.2 ADS agrees to sign and deliver any necessary documents and approvals required to provide VDYS with all legal and financial rights required to build, operate and
manage the AFJ Rig under this Agreement.



2.3 VDYS agrees to reimburse to ADS a
placement fee of 6% of the Purchase Price and reimburse to ADS unallocated expenses equal to 2% of the Purchase Price amount from the proceeds of the funding to VDYS. Such payment shall occur within 10 business days of payment by ADS of the Purchase
Price.



3. Operating Obligations.



3.1 At its own expense, VDYS shall be solely responsible for the management,
operation, maintenance, repair, overhaul, and upgrade of the AFJ Rig during the term of this Agreement and shall maintain the AFJ Rig in commercially operable condition during the term of this Agreement.



3.2 VDYS shall provide all planning, material procurement, manpower, transportation,
marketing & sales support, and operations supervision related to AFJ Rig operation as required for the conduct of commercial operations through the use of in-house labor and contract services.



---

3.3 VDYS shall prioritize drilling contracts on a commercially reasonable efforts basis to provide priority deployment of
the AFJ Rig ahead of other comparable equipment that may be operated by VDYS. In the event that the AFJ Rig is available for use, VDYS will use its commercially reasonable efforts to utilize the AFJ Rig.



3.4 VDYS shall provide an accounting, reporting & cash collection function for the AFJ
Rig within 10 business days of the end of each calendar quarter during the term of the Agreement.



3.5 VDYS shall comply with all laws & regulations relating to the development and operation of the AFJ Rig for the term of the Agreement.



3.6 VDYS assumes liability for all risk of loss and damage to the AFJ Rig. VDYS shall carry insurance on the AFJ Rig of such amounts and
types of coverage as are customary in the industry and comparable in coverage and amount to policies carried by VDYS covering its other equipment. VDYS shall list ADS as an additional insured under such policies covering the AFJ Rig.



3.7 VDYS shall indemnify, defend and hold ADS harmless from and against any and all
liability, judgments, costs, damages, claims or demands, including reasonable attorneys fees, arising out of VDYS operation and maintenance of the AFJ Rig, including but not limited to any breach by VDYS of its obligations under this
Agreement, third party claims and claims for employee liability, except to the extent arising out of the gross negligence or willful misconduct of ADS or any of its affiliates. If any such action or proceeding be brought against ADS, VDYS, upon
notice from ADS, shall defend such action or proceeding at its sole expense by counsel reasonably satisfactory to VDYS. ADS shall indemnify and hold VDYS harmless from and against any and all liability, judgments, costs, damages, claims or demands,

3.10 ADS shall agree to remain in good standing under the laws of the State of Delaware and
to meet all its financial and legal obligations as they arise to the extent that the failure to remain in good standing or meet such obligations could reasonably be anticipated to impair the ownership or operations of the AFJ Rig. In the event that
ADS fails to timely meet such financial or legal obligations within 90 calendar days of when ADS is notified of its failure to meet its obligations, Verdisys shall have the option to purchase and take title to the AFJ Rig for $50,000 in cash and
then terminate this Agreement.
