This Master Agreement For Terms and Conditions of Sale (“Agreement”) governs the sale of products and services by EKU Power Drives Inc., a Delaware corporation with its principal place of business at 2407 Timberloch Pl Suite D, The Woodlands, TX 77380 (“Seller” or “Service Provider”) to any customer that places an Order (defined below) referencing or linking to this Agreement (“Customer”). By submitting an Order, clicking ‘I Agree,’ or otherwise accepting Products or Services from Seller, Customer agrees to be bound by this Agreement. Seller and Customer may be referred to individually as a “Party” and collectively as the “Parties.”

1. Parties and Scope of Agreement

1.1 This Agreement governs the sale of products and services (collectively, the “Products and Services”) by Seller to Customer as described in individual purchase orders or statements of work (each, an “Order”).

1.2 Customer acknowledges that this Agreement is made available via hyperlink on Seller’s website and is incorporated by reference into each Order. Customer accepts and agrees to be bound by this Agreement by: (a) clicking an “I Agree” or similar assent button; (b) submitting, accepting, or performing under an Order that references this Agreement; or (c) accepting delivery of or payment for Products or Services.

1.3 The terms of this Agreement apply to all Orders unless expressly agreed in a written agreement executed by Seller.

2. Definitions

2.1 “Products” means the tangible goods manufactured or sold by Seller and supplied to Customer under this Agreement. Products may include or utilize firmware that is required to operate and communicate with various elements of the hardware (collectively, “Firmware”). Products provided by Seller may also include software that will be subject to separate software license terms and conditions, which the Customer must agree to be bound by prior to using such software.

2.2 “Services” means the installation, maintenance, consulting, or other services that Seller performs for Customer under this Agreement or any Statement of Work.

2.3 “Deliverables” means any tangible or intangible work product, reports, documents, software, or other materials that Seller delivers to Customer in the course of performing the Services.

2.4 “Service Levels” means the performance targets, response times, completion dates, or other measurable criteria (if any) expressly stated in an Order or Statement of Work for the Services.

2.5 “Statement of Work” or “SOW” means a document executed by the Parties that describes in detail the scope, schedule, Deliverables, and Service Levels (if applicable) for particular Services provided by Service Provider.

3. Ordering, Delivery of Products, and Performance of Services

3.1 Customer shall submit Orders or SOWs in writing, specifying the Products and/or Services desired, any Deliverables, delivery or performance dates, and other relevant details. For any respective Order to be effective or binding, Seller must provide written acceptance for such Order. Seller’s acceptance of an Order constitutes Seller’s agreement to supply the Products or Services, and Customer’s submission of such Order constitutes Customer’s agreement to this Agreement. Any additional or different terms proposed by Customer, whether in a Order, SOW, acknowledgment, invoice, or otherwise, are hereby rejected and shall be void and of no effect, even if Seller does not expressly object to such terms. In the event of a conflict in terms between any Order or SOW and this Agreement, the terms of this Agreement will control.

3.2 For Products, Seller will use commercially reasonable efforts to meet the delivery dates specified in the Orders. Delivery terms shall be FOB Seller’s facility (Incoterms 2020), and risk of loss or damage shall pass to Customer immediately upon Seller’s tender of the Products to the first carrier at Seller’s facility.

3.3 Title to all Products shall remain with Seller, and Seller shall retain a purchase money security interest in the Products, any replacements, and the proceeds thereof, until Seller has received payment in full of all amounts owed by Customer, at which time title shall pass to Customer. Customer authorizes Seller to file UCC financing statements without Customer’s signature to perfect Seller’s security interest. Customer agrees to execute any documents and take any actions reasonably requested by Seller to perfect or protect this security interest.

3.4 Partial shipments are permitted. Delay in delivery of any installment shall not relieve Customer of its obligation to accept remaining deliveries.

3.5 Acceptance of Services, Deliverables, and Products. Unless different acceptance criteria or periods are specified in an applicable Order or SOW, Customer shall have five (5) business days after Seller’s completion of the Services or delivery of any Deliverable to notify Seller in writing of any material nonconformity. If Customer fails to provide such notice within that period, the Services and Deliverables shall be deemed accepted. Customer’s sole remedy for non-conforming Services or Deliverables shall be the reperformance of the affected Services or correction or replacement of the Deliverable, at Seller’s option.

3.6 Change Requests. Any change to the scope, schedule, or Service Levels of the Services must be agreed in a written change order signed by both Parties. Seller shall be entitled to an equitable adjustment in price and/or schedule to account for any approved change.

4. Pricing and Payment Terms

4.1 Prices for Products and Services are as stated in the applicable Order and shall be irrevocable once the Order is accepted by Seller. Unless otherwise specified, prices are exclusive of taxes, duties, shipment, or any applicable tariffs that may be assessed upon Products, all of which shall be paid by Customer.

4.2 Customer shall pay each undisputed invoice within fifteen (15) days from the invoice date, without setoff or deduction.

4.3 Any amount not paid when due shall accrue interest at the lesser of (a) one and one-half percent (1.5%) per month or (b) the maximum rate permitted by applicable law, calculated daily and compounded monthly.

4.4 If any payment is past due for more than ten (10) days, Seller may, upon written notice, suspend performance, withhold additional shipments, and/or require cash in advance until all outstanding amounts, including interest and fees, are paid in full.

4.5 Customer shall reimburse Seller for all reasonable costs of collection, including attorneys’ fees and all amounts recoverable under Chapter 38 of the Texas Civil Practice and Remedies Code, incurred in recovering any past-due amounts.

4.6 All payments shall be made in U.S. dollars by wire transfer or another method acceptable to Seller.

4.7 Milestone or Time-and-Materials Billing. Unless expressly stated as fixed price in the applicable Order or SOW, Services shall be provided on a time-and-materials basis at Seller’s then-current rates, and Seller may invoice Customer monthly in arrears for Services performed and expenses incurred.

5. Warranties and Disclaimers

5.1 Seller warrants solely to Customer that the Products will, at the time of shipment, materially conform to Seller’s published specifications or documentation and will be free from material defects in material and workmanship for a period of twelve (12) months from the date of shipment (the “Warranty Period”).

5.2 Seller’s entire liability and Customer’s exclusive remedy for breach of the foregoing Product warranty is, at Seller’s option, repair or replacement of the non-conforming Product or refund of the purchase price paid for such Product. All returned Products must be accompanied by a return material authorization number issued by Seller.

5.3 Services Warranty. Seller warrants solely to Customer that the Services will be performed in a professional and workmanlike manner consistent with generally accepted industry standards for similar services.

5.4 Exclusive Remedy for Services. Customer’s exclusive remedy and Seller’s entire liability for breach of the Services Warranty shall be, at Seller’s option, (a) re-performance of the non-conforming Services, or (b) refund of the portion of the fees paid that are attributable to the non-conforming Services.

5.5 Warranty Claim Process. To file a warranty claim, Customer shall notify Company in writing within the applicable Warranty Period promptly upon discovery of any alleged defect and shall provide reasonable documentation supporting the claim, including product identification information, proof of purchase, and a description of the issue. Upon receiving such notice, Company may request additional information, require Customer to perform basic diagnostic steps, or issue a Return Material Authorization (“RMA”) with shipping instructions. No Product shall be returned without an RMA, and Customer shall bear shipping costs to Company’s designated facility; if Company determines the claim is valid, Company will, at its option, repair or replace the defective product or refund the purchase price in accordance with the exclusive warranty remedies commonly used in commercial manufacturing agreements. Products returned without a valid RMA, or found not to be defective or outside the Warranty Period, may be returned to Customer at Customer’s expense.

5.6 Warranty Exclusions. The warranty shall not apply to any Product that: (a) has been subjected to misuse, abuse, neglect, improper installation, improper storage, improper commissioning, or operation outside of Company’s published specifications, operational limits, pressure/temperature ratings, or environmental classifications; (b) has been damaged due to exposure to corrosive or abrasive media, chemical attack, scaling, hydrogen sulfide (H₂S), high-chloride environments, or other oil-and-gas-specific process conditions not expressly identified in the applicable specifications; (c) has failed due to vibration, shock loading, excessive cycling, water or fluid ingress, contamination, unfiltered fluids, or other field conditions inconsistent with standard oilfield equipment handling practices; (d) has been altered, modified, disassembled, repaired, refurbished, or re-manufactured by any party other than Company or its authorized service personnel; (e) fails due to Customer’s failure to follow Company’s installation manuals, maintenance schedules, operational procedures, filtration requirements, or safety guidelines; or (f) is combined with, connected to, installed on, or used in conjunction with third-party equipment, instrumentation, controls, fluids, or chemicals not supplied or expressly approved in writing by Company.

5.7 WARRANTY DISCLAIMER: EXCEPT AS EXPRESSLY SET FORTH IN THIS SECTION 5 WITH RESPECT TO PRODUCTS AND SERVICES, SELLER MAKES NO OTHER WARRANTY, EXPRESS, IMPLIED, OR STATUTORY, AND SPECIFICALLY DISCLAIMS, AND CUSTOMER WAIVES ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AS WELL AS ANY WARRANTIES ARISING FROM USAGE OF TRADE OR COURSE OF DEALING. CUSTOMER ACKNOWLEDGES THAT THIS DISCLAIMER IS A MATERIAL PART OF THIS AGREEMENT AND THAT PRICES REFLECT THIS ALLOCATION OF RISK.

6. LIMITATION OF LIABILITY AND WAIVER OF CERTAIN DAMAGES

6.1 TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL SELLER BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION LOST PROFITS OR REVENUES, LOSS OF USE, OR LOSS OF DATA, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

6.2 SELLER’S AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY ORDER, REGARDLESS OF THE THEORY OF LIABILITY, SHALL NOT EXCEED THE TOTAL AMOUNT PAID BY CUSTOMER TO SELLER FOR THE SPECIFIC PRODUCT(S), SERVICE(S), AND/OR DELIVERABLE(S) GIVING RISE TO THE CLAIM DURING THE SIX (6) MONTH PERIOD PRECEDING THE EVENT FROM WHICH THE LIABILITY AROSE. THE PARTIES AGREE THAT THE LIMITATIONS IN THIS SECTION 6 ARE FUNDAMENTAL ELEMENTS OF THE BASIS OF THE BARGAIN.

6.3 THE LIMITATIONS IN THIS SECTION 6 SHALL NOT APPLY TO THE EXTENT OF SELLER’S WILLFUL MISCONDUCT OR GROSS NEGLIGENCE.

7.1 Seller shall exclusively own and retain all rights, title, and interest in and to all intellectual property, including but not limited to copyrights, patents, trade secrets, trademarks, and any other proprietary rights, in and to the Products and Services, including all Deliverables and Firmware, whether pre-existing, developed independently, or created in connection with the performance of the Services under this Agreement. This includes all designs, specifications, software, documentation, processes, methodologies, know-how, and any derivatives or modifications thereof. Nothing in this Agreement shall be construed to transfer or assign any intellectual property rights to Customer. Customer shall acquire no ownership interest or rights of any kind in the Deliverables or any other intellectual property of Seller, except for a limited, non-exclusive, non-transferable license solely to use the Deliverables for Customer’s internal business purposes, subject to full payment and strict compliance with this Agreement.

7.2 Customer shall not attempt to reverse engineer, decompile, or disassemble any element of the Products or Services, including Firmware provided under this Agreement. Additionally, Customer shall not alter, repair, modify, or create derivative works of any Products or Services without Seller’s prior written consent. Unless at Seller’s direction, any unauthorized modification, repair, or alteration of the Products or Services shall void all warranties and Seller shall have no liability for any resulting damages or claims arising under Customer’s breach of this paragraph.

7.3 License to Deliverables and Firmware. Subject to Customer’s full payment of all amounts due under this Agreement, Seller grants to Customer a non-exclusive, non-transferable, revocable license to use the Deliverables, including any Firmware provided with or embedded in the Products sold under this Agreement, solely for Customer’s internal business purposes in connection with the operation of the Products. This license does not include any right to sublicense, distribute, reverse engineer, or modify the Deliverables or Firmware. Any use of Deliverables or Firmware constitutes acceptance of the license terms set forth herein. No other rights or licenses are granted by implication, estoppel, or otherwise. This license terminates immediately upon Customer’s breach of Section 7 or Section 9 of this Agreement.

7.4 All rights not expressly granted herein are expressly reserved by Seller.

8. Indemnification. Customer shall defend, indemnify, and hold harmless Seller and its affiliates, and their respective directors, officers, employees, and agents, from and against any and all claims, suits, liabilities, damages, losses, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to (i) Customer’s combination of the Products, Services, or Deliverables with other products or systems, modification of the Products, Services, or Deliverables, or use of the Products, Services, or Deliverables for any purpose not expressly authorized by Seller; (ii) Customer’s breach of any term of this Agreement; (iii) Customer’s negligence, willful misconduct, or violation of applicable laws; and (iv) any claim that the use, resale, or export of the Products, Services, or Deliverables by Customer infringes the rights of any third party, except to the extent such claim is solely attributable to the unmodified Products, Services, or Deliverables as supplied by Seller. The limitation of liability described above shall not serve to limit Customer’s indemnity obligations in any way.

9. Confidentiality

9.1 Each party that receives Confidential Information from the other party (the “Receiving Party”) agrees that it shall not disclose to any third party, and shall not use for any purpose other than as necessary to perform its obligations or exercise its rights under this Agreement, any non-public, confidential or proprietary information disclosed by the other party (“Disclosing Party”), whether oral, written, electronic or other form, including, without limitation, business plans, financial data, technical information, product designs, trade secrets, and any information that is identified as confidential or that a reasonable person would understand to be confidential (“Confidential Information”). The obligations in this Section shall not apply to information that: (i) is or becomes generally available to the public through no fault of the Receiving Party; (ii) was rightfully in the Receiving Party’s possession without restriction prior to disclosure by the Disclosing Party; (iii) is rightfully disclosed to the Receiving Party by a third party without restriction; or (iv) is independently developed by the Receiving Party without use of or reference to the Disclosing Party’s Confidential Information.

9.2 Use and Disclosure. The Receiving Party agrees to protect the confidentiality of the Disclosing Party’s Confidential Information using the same degree of care that it uses to protect its own confidential information of similar nature, but in no event less than a reasonable standard of care. The Receiving Party may disclose Confidential Information to its employees, agents, or contractors who have a legitimate need to know such information for purposes of this Agreement and who are bound by obligations of confidentiality at least as protective as those set forth herein. Any disclosure required by law or court order shall not be a breach of this Agreement, provided that the Receiving Party gives the Disclosing Party prompt written notice of such requirement (unless legally prohibited) and cooperates in any effort to seek a protective order or other remedy.

10.1 THIS AGREEMENT AUTOMATICALLY RENEWS UNLESS TIMELY TERMINATED. Unless earlier terminated in accordance with this Agreement, the initial term of this Agreement shall commence on the Effective Date and shall continue for one (1) year from the Effective Date (the “Initial Term”), at which time the term of this Agreement shall automatically be extended for additional successive one-year terms (each, a “Subsequent Term,” and the Initial Term and all Subsequent Terms, collectively, the “Term”) unless, on or before ninety (90) days prior to the expiration of the then current Term, either party provides written notice to the other party of its intent to terminate its participation in this Agreement upon the expiration of such Term.

10.2 Either Party may terminate this Agreement for a material breach by the other Party that remains uncured thirty (30) days after receipt of written notice detailing the breach; provided, however, that Seller may terminate immediately upon written notice if Customer (a) fails to pay any undisputed amount when due and such failure continues for ten (10) days after written notice, (b) becomes insolvent, files for bankruptcy, or assigns assets for the benefit of creditors, or (c) breaches Section 7 (Intellectual Property).
