No terms or conditions submitted by Supplier that are in addition to, different from or inconsistent with those contained in the Purchase Order, including Supplier’s standard printed terms and conditions, and any terms and conditions contained in any Supplier quotation, invoice, order acknowledgment, confirmation, acceptance, bill of lading or other instrument or notification, shall be binding upon Client unless specifically and expressly agreed to in writing by Client.


If and to the extent that the Purchase Order includes any estimates, forecasts, approximations or requirements of or by Client relating to the purchase of Goods and/or Services, Supplier acknowledges and agrees that such estimates, forecasts, approximations or requirements: (a) are estimates only; (b) are not guaranteed; and (c) do not create a commitment to purchase any volume or quantity of Goods and/or Services from Supplier.


Supplier shall deliver the Goods and/or perform the Services at the Delivery Point in accordance with the Delivery Schedule. Supplier acknowledges and agrees that time is of the essence for the delivery or performance under the Purchase Order.

Risk of loss of the Goods remains with Supplier until their final inspection and acceptance by Client. Notwithstanding any acceptance by Client at Supplier’s facilities, Goods and Deliverables are subject to final inspection and acceptance by Client upon receipt at the Delivery Point. Final inspection and acceptance by Client does not relieve Supplier from any of its obligations under the Purchase Order, and shall not be construed to prejudice any of Client’s rights or remedies under the Purchase Order or at law.

Supplier shall comply with Client’s general quality requirements which are identical to the requirements set forth in the latest issue of the “Quality Requirements for Suppliers” document number DQD 4.6-40. Supplier can ask to receive a copy of the latest issue.


Client shall pay to Supplier the Price. The Price is inclusive of all costs and expenses of Supplier in delivering the Goods and/or performing the Services. Separate invoices, in duplicate, must be remitted by Supplier based on whether Goods were delivered and/or Services rendered. Invoices must be addressed to Client’s accounts payable department as indicated on the Purchase Order.

Errors or lack of supporting documentation, as specified in the Purchase Order, are cause for withholding payment until such error or lack of supporting documentation is corrected.

All payments owed to Supplier hereunder are contingent upon Supplier providing Client, upon request, evidence of Supplier’s compliance with the foregoing. For greater clarity, the foregoing does not grant Supplier the right to register a Lien against Client or its assets.


If Client places additional purchase orders for Goods and/or Services covered by a Purchase Order and such purchase orders could have been combined in such Purchase Order to benefit from a price advantage, Supplier acknowledges and agrees that such price advantage shall apply to the relevant purchase orders. In such event, the refund, credit or discount reflecting such price advantage shall be evidenced by way of a credit note applicable, at Client’s entire discretion, to any current or future invoices.

8.    TAXES

With the exception of applicable Buyer’s Taxes, Supplier shall be responsible for all taxes, including withholding, fees, interests and penalties, which are, or may be, imposed or assessed by any governmental authority or agency, or any taxing authority, as a result of, or in connection with this Purchase Order.

If any Buyer’s Taxes are applicable and chargeable, Supplier must provide to Client a valid invoice in accordance with the applicable tax legislation. If applicable, no Buyer’s Taxes shall be charged by Supplier when Client provides a valid exemption certificate to Supplier. For the avoidance of doubt, when payment is subject to withholding taxes, unless Supplier provides Client with a valid and timely exemption documentation, Client will withhold from payment the amount required to satisfy tax withholding obligations under applicable laws.


In respect of the Goods, Supplier represents and warrants that: (a) it has good title to the Goods and the transfer of title to Client is free and clear of Liens; (b) the Goods conform to any specifications and/or standards provided by Client, or by Supplier and approved by Client; (c) the Goods are provided in accordance with applicable laws and, apart from the Goods for which the design is provided by Client, are free from defects in design; and (d) the Goods are free from defects in materials and workmanship for a period of 24 months from acceptance of the Goods by Client or for a longer period as may be provided in the Purchase Order. For greater certainty, the warranty set out in (a), (b) and (c) above applies for an unlimited period of time.

In respect of the Services, Supplier represents and warrants that the Services (a) conform to any specifications and/or standards provided by Client, or by Supplier and approved by Client; (b) are provided in accordance with applicable laws; and (c) will be performed expeditiously and consistent with good business practices and professional standards of other top-tier leading service providers of similar services in similar circumstances.

In supplying the Goods and performing the Services, Supplier must: (a) comply with and ensure that Supplier Personnel and Subcontractors comply with all applicable laws and regulations; (b) comply with Client’s sustainability policies available at Dehavilland.com (c) to the extent that Supplier Personnel or Subcontractors are required to enter into Client’s site or property, ensure that they (i) comply with Client’s written health, safety and environmental policies and standards provided to Supplier, and (ii) acknowledge that they enter onto Client’s site or property at their own risk; (d) represent and warrant that it has not violated and will not violate, in connection with the Purchase Order, any applicable anti-corruption law; (e) represent and warrant that it is in compliance with and will continue to comply with all Export Laws and that it has not been and is not currently included on any government sanctions list or any other denied/debarred party list; and (f) inform Client in writing of any changes in such Export Laws if so applicable, and shall obtain and renew any necessary governmental export permit or similar authorization if so required. For all controlled goods and technologies covered by the Purchase Order, Supplier shall send to Client’s export control group a written notice indicating all controlled goods and technologies, as per the requirements of any governmental agency having authority. All communication inquiries or representations regarding controlled goods and technologies shall be sent by e-mail to: Director.SupplyChain@dehavilland.com

Supplier warrants that, at all times, it shall remain in good standing with, and pay promptly when due, all amounts required by any authority having jurisdiction over the Purchase Order or Supplier, with respect to health and safety matters, workers’ compensation and other employee related matters, and shall, upon Client’s request, provide a certificate of good standing from such authority.


Supplier will comply and provide all the information necessary for Client and/or Client’s customers to comply with all laws, statutes, decrees, treaties, regulations, orders, directives, or norms (“Environmental Regulations”) issued by any relevant governmental or other regulatory or administrative authority with respect to public health or safety or the environment, as they relate to the Services or the Goods.

As part of Supplier’s compliance with Environmental Regulations, Supplier shall fulfill at all times the requirements of the European Regulation (EC) No. 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (“REACH”).


Without limiting Supplier’s obligations or liabilities hereunder, Supplier shall, at its sole costs and expenses, and for the duration of the Purchase Order and all applicable warranty periods, purchase and maintain the following insurance coverage:

Supplier shall provide (i) an endorsement including Client and its directors, officers, employees, agents and representatives as additional insureds; (ii) an endorsement including a cross liability Section, noting that each of the parties comprising the insured are considered as a separate entity, the insurance applies as if a separate policy has been issued to each party, and no “insured-versus-insured” exclusion exists in the policy; and (iii) an endorsement waiving all express or implied rights of subrogation against Client;
  2. workers’ compensation insurance in compliance with the applicable laws of each jurisdiction affected by the Goods and/or Services, with a waiver of subrogation in favour of Client, if available;

  5. if Supplier has property belonging to Client or Client’s customers in its care, custody or control, property insurance covering loss or damage to the property on an “all risks” basis in an amount sufficient to cover the full cost of repair or replacement. Such policy shall include an endorsement waiving all express or implied rights of subrogation against Client.

Supplier shall prior to execution of the Purchase Order and subsequently prior to renewal of the required insurances provide to Client or its designee certificates of insurance and endorsements as evidence of the insurance required under the Purchase Order. To the extent Supplier uses a Subcontractor for any portion of the Goods and/or Services, Supplier shall ensure that such Subcontractor is subjected to the same insurance requirements contained in this Section 11.


In any event, if Supplier is processing Client’s Confidential Information, or if Supplier has dependencies on its computer systems to deliver the Goods and/or perform the Services, Supplier shall maintain an information security policy and/or process to ensure confidentiality on such systems and prevent viruses, malware and cyberattacks. Client’s Confidential Information shall be securely deleted from all electronic media reused, destroyed when defective, sent for repair or no longer required.

In the event that a confidentiality agreement has been executed between Client and Supplier, such agreement shall take precedence over the following.

The parties agree that they shall: (a) not use Confidential Information for any purpose other than as may be required for the performance of their obligations under the Purchase Order; (b) not directly or indirectly disclose or allow access to any Confidential Information to or by any third party except as expressly permitted in the Purchase Order; (c) take all measures reasonably required to maintain the confidentiality and security of all Confidential Information; and (d) if receiving party suspects or becomes aware of any unauthorized disclosure of or access to any Confidential Information: (i) immediately notify disclosing party; (ii) enforce against any person that is or may be engaging in such unauthorized disclosure or access any rights that receiving party has to require such person to cease such unauthorized activities; and (iii) do all things, execute all documents and give all assistance reasonably required by disclosing party in connection with such unauthorised disclosure.

The parties may disclose Confidential Information if and to the extent required by applicable law, provided, however, that receiving party must first give disclosing party notice of such compelled disclosure and provide disclosing party with an opportunity to take such steps as it desires to contest such disclosure or seek a protective order. The parties may disclose Confidential Information to: (a) their professional advisors if and to the extent that such persons need to know such Confidential Information in order to provide the applicable professional advisory services relating to the parties’ business; and (b) Supplier Personnel and Subcontractors if and to the extent that such persons need to know such Confidential Information to perform their respective obligations under the Purchase Order; provided, however, that any such person has entered into an agreement with Supplier that includes confidentiality obligations in respect of such Confidential Information that are not less stringent than those contained in this Section 13.

All Confidential Information shall be returned to disclosing party or destroyed upon disclosing party’s request with a certified written confirmation of such destruction, upon completion or termination of the Purchase Order provided, however, that receiving party may retain a copy of the Confidential Information held in its general computer back-up records made for internal recovery procedures. This Section 13 shall survive for a period of 5 years following the return or destruction of the Confidential Information.

Supplier agrees to assign, and hereby assigns, to Client any and all intellectual property rights created or acquired in the performance of the Services.

All intellectual property (i) created or acquired by a party, at any time, independently of the performance of the Purchase Order; or (ii) owned or licensed by a party prior to the earlier of the date of the Purchase Order or the initial performance of any obligation under the Purchase Order (collectively, “Background Intellectual Property”), remain the property of such party. Supplier hereby grants to Client and its affiliates a perpetual, non-exclusive, sub-licensable, transferable, worldwide license to use Supplier Background Intellectual Property in connection with the use, resale, modification, reproduction and disclosure of the Goods and Deliverables.

If either party is prevented from performing or is unable to perform any of its obligations under the Purchase Order due to a Force Majeure Event, and has given prompt written notice to the other party, then the affected party’s failure to perform shall be excused and the time allowed for performance shall automatically be extended to account for the applicable period of delay or inability to perform due to such Force Majeure Event.

Any adjustments required following a Force Majeure Event shall be reflected in the Purchase Order by way of a written amendment in accordance with Section 23. In all cases, Supplier shall not be entitled to payment for costs related to such adjustments.

In all cases, Supplier bears all costs and expenses incurred by Client, its affiliates and their customers in relation to the repair or replacement of the defective Goods and the performance of the non-compliant Services. Supplier warrants and guarantees the Goods which are non-compliant with Section 9(c) for an additional period of 12 months from the date of repair or replacement;

In such event, Supplier shall be entitled to (i) the portion of the Price applicable to the Goods delivered and/or Services performed as of the effective date of termination; and (ii) the actual cost incurred as of the effective date of termination for work in progress, taking into consideration the agreed upon lead time.

Client may also terminate the Purchase Order upon the occurrence of any of the following events: (a) Supplier becomes insolvent; (b) insolvency or similar proceedings are commenced against Supplier; (c) Supplier is in breach or default of any provision of the Purchase Order, which breach or default is not cured within the prescribed period in a written default notice from Client; or (d) Client has reasonable grounds to believe that Supplier’s performance (including timely performance) is in jeopardy and Supplier fails to provide adequate assurance within 5 days of receiving a written notice to that effect.
