1. Applicability

(1) These standard terms and conditions shall apply to all contracts between STACKFORCE GmbH and its customers in respect of services (Leistungen), in so far as not otherwise explicitly agreed upon in writing.

(3) The standard terms and conditions of STACKFORCE GmbH shall apply exclusively. Contrary or deviating terms of the other party shall only be binding if and to the extent that STACKFORCE GmbH explicitly consents to their validity in writing. The standard terms and conditions of STACKFORCE GmbH apply, even if STACKFORCE GmbH fulfills the order of the customer without reservation in the knowledge of contrary or deviating terms of the customer. Deviating agreements apply only to a particular agreement and not to future agreements, unless otherwise explicitly agreed upon in writing.

(4) The standard terms and conditions shall also apply to all future agreements between STACKFORCE GmbH and its customers for services (Leistungen).

2. Scope of orders

In case it is not stated differently within the offer, it remains valid until four weeks after the date of the offer. STACKFORCE GmbH provides services (Dienstleistungen) (consultation and support of the customer) at its own responsibility. The customer is, however, himself responsible for the results desired and achieved by him. In the case of project-services, STACKFORCE GmbH is responsible for the results to be achieved as well as the management, control, and observation of the provision of the service.

(2) STACKFORCE GmbH and the customer are each authorized to apply in writing for modifications to the agreed upon scope of services. STACKFORCE GmbH and/or the customer shall examine the possibility of implementing this modification after service of the application therefore. The result of this examination shall be communicated to the other party in writing without delay. STACKFORCE GmbH is authorized to invoice its costs to the ordering party, in so far as the ordering party's application for modification requires a comprehensive and costly examination. The contractual adjustments necessary for such an examination and/or for a modification to the agreed upon scope of services shall be set forth in a supplementary agreement.

3. Fulfillment of orders

(1) Orders shall be fulfilled observing the current state of science and technology.

(2) Only STACKFORCE GmbH is authorized to direct its employees.

(4) STACKFORCE GmbH is authorized to obtain the services of third parties for the fulfillment of orders. STACKFORCE GmbH alone, however, remains directly obligated to the customer.

(5) For project-services, delivery times shall be counted from the date STACKFORCE GmbH acknowledges the order but not before all details of the order have been fully clarified; accordingly, this applies to delivery dates as well. All delivery times and dates shall be conditional on availability and the timely receipt of vendor deliveries.

(6) Unless stipulated otherwise, the criterion for adherence to the delivery times and dates is the day of placing the service (Leistung) at the disposal of the customer at the registered office of STACKFORCE GmbH.

(7) In cases of force majeure the contractual obligations of both parties are suspended and the delivery times and dates for the fulfillment of such contractual obligations shall be postponed accordingly; force majeure shall include, but is not limited, to strikes in internal and external companies, freight forwarding delays, machinery breakdown, government actions as well as other circumstances beyond the control of either party. Any occurrence of force majeure shall be immediately reported to the respective other party. Three months at the earliest after the receipt of such notification, both parties shall have the right to withdraw from this contract.

(8) In the event of non-adherence to the delivery times and dates in case of project-services the customer shall be entitled to claim damages in lieu of performance for non-performance or failure to render performance as owed according to § 281 BGB (German Civil Code) and to raise a plea of lack of performance of the contract according to § 323 BGB (German Civil Code) but only after having given STACKFORCE GmbH a reasonable grace period for the delivery in combination with a caveat -notwithstanding the provisions of §§ 281, 323 BGB (German Civil Code) - stating that, after expiration of the grace period, acceptance of the project-services will be rejected; once the grace period has expired without success, any claim for delivery shall be excluded.


4. Duties of the customer

If need be, the customer will obtain functional work stations (Arbeitsplätze), at no cost to STACKFORCE GmbH, for the employees of STACKFORCE GmbH or for third parties mandated by STACKFORCE GmbH.

(3) The customer will furthermore participate in any way necessary in the fulfillment of the order.

(4) If the customer does not or does not timely fulfill his obligations under paras. (1) - (3) and if this leads to delays and/or additional work, the agreed upon time frame and/or the agreed upon remuneration shall increase accordingly.

(4) In case of default, interest shall be payable at the rate of nine percentage points above the base rate of the European Central Bank. The right to claim further damages shall not be excluded. The rules of §288 para (1) BGB (German Civil Code) remain unaffected.

(6) The customers can only set off non-appealable or unchallenged counterclaims or counterclaims recognized by STACKFORCE GmbH.

6. Acceptance

(1) Project-services shall be accepted by the customer as soon as STACKFORCE GmbH has demonstrated compliance with the agreed-upon description of services (Leistungsbeschreibung). Immaterial deviations do not authorize the ordering party to refuse acceptance. The obligation to cure defects within the scope of liability for warranties remains unaffected thereby.

(2) Confirmation of compliance with the agreed upon description of services shall be prepared by both parties by the mutual execution of a protocol of acceptance.

(3) Placing the result of the project (des Werkes) in operation and/or the productive use of the project or of parts of the project shall be deemed to be an acceptance.

(4) Following the rules of §640 para (1) sentence 2 BGB (German Civil Code), it corresponds to an acceptance, if the customer does not execute the acceptance of the services or of the results of the project within an adequate time determined by STACKFORCE GmbH, although the customer is obliged to do so.

7. Warranties in the case of project-services

(1) STACKFORCE GmbH warrants that project-services are performed free from defects of material or of title. In particular the project-services performed are in accordance with the agreed-upon description of services (Leistungsbeschreibung) and with the agreed-upon scope of services (Leistungsumfang).

a) At the discretion of STACKFORCE GmbH, STACKFORCE GmbH shall cure the defects or perform new project-services.

b) In the case of failure to cure within a reasonable time, the customer may at his own choice reduce the payment or, insofar as the value or usability of the project should be substantially reduced, demand rescission of the contract, provided that claims for further damages and claims for reimbursement of expenses remain unaffected hereof.

c) In the case of defects of material or of title, the customer shall notify STACKFORCE GmbH immediately hereof in writing.

(3) The limitation period for warranty claims shall be twelve months from rendering of the respective service and acceptance of the project respectively. In case the legal provisions in § 438 para.

(5) Apparent errors such as typographical errors, calculation errors, defects of form, etc., which are contained in a report, expert opinion, or other professional utterance of employees of STACKFORCE GmbH may be corrected by STACKFORCE GmbH at any time.

c) STACKFORCE GmbH has willfully or negligently caused damage to life, body or health of persons,

d) STACKFORCE GmbH has violated essential contractual obligations. Essential contractual obligations are obligations, the fulfillment of which is a prerequisite of the proper implementation of the contract and the customer is justified in relying on routinely.

(3) In the event of violation of essential contractual obligations, according to it. 8 para. 2 (d) STACKFORCE GmbH’s liability shall be limited to the typically foreseeable amount of damages in cases of ordinary negligence. This claim of damages is subject to the limitation period applicable for warranties under it. 7. para. (3) above.

(4) The exclusion of liability shall not be applicable to claims arising out of the German Product Liability Act (Produkthaftungsgesetz).

(5) The aforementioned regulations shall not imply a change of burden of proof at the expense of the customer.

(6) In the event STACKFORCE GmbH defaults on project-services, the customer shall be entitled - as far as he proves that he has suffered damages therefrom - to claim a compensation in the amount of 0.5% for every accomplished week of delay, totaling however not more than 5% of the total payment for that part of the service not timely completed. The provision of this it. 8 para. (2) remains unaffected. The customer shall be obliged, upon the request of STACKFORCE GmbH, to declare within a reasonable time, whether he rescinds the contract because of the delay of the project-services and/or claims damages instead of performance or requests continued performance of the services; once the grace period has expired without success, any claim for delivery shall be excluded.

(3) The obligation under para. (1) applies to both parties after the expiration of the mandate for another two years.

STACKFORCE GmbH reserves, however, in any case, a non-remunerated and non-exclusive right to use such work product for the purposes of research and education.

(2) STACKFORCE GmbH carries no responsibility if technical documentation provided to it by the customer or within the customer's mandate breaches existing copyrights, industrial property rights, or other rights of third parties.

(3) In those cases of termination under paras. (1) and (2) the customer shall pay the remuneration minus that part of the remuneration for the agreed-upon scope of services, which was saved by the termination. STACKFORCE GmbH has an additional claim to payment for the services and costs which accrue in connection with the termination, also in respect of third parties.

(4) If the termination occurs for reasons to be attributed to STACKFORCE GmbH, then STACKFORCE GmbH has a claim to payment for the services (Leistungsumfang) brought up to that time only in so far as they can be used by the customer.

(5) Termination requires the written form in any case.

14. Issuance of documents and things, retention right
