Hydro-Air Components, Inc. a/k/a Zehnder Rittling (“HAC”) purchases goods and services (“Deliverables”) only on the terms and conditions herein, which constitute the entire agreement between it and a vendor/seller (“Seller”).

1.0  Offer and Acceptance; Terms Exclusive

This purchase order (“Purchase Order”) includes these Terms and Conditions and all specifications, drawings, data and additional or special terms and conditions contained herein, attached hereto or incorporated herein by reference (together, the “Specifications”).  ACCEPTANCE OF THIS OFFER IS EXPRESSLY LIMITED TO THESE TERMS AND CONDITIONS.  Any additional or different terms proposed by the Seller in any order acknowledgement form, invoice or other writing are rejected and shall not be binding on HAC unless expressly agreed to in writing by HAC. This Purchase Order will be deemed accepted whenever Seller confirms its acceptance of this Purchase Order or commences furnishing any of the Deliverables specified herein.  IF THE PURCHASE ORDER IS DEEMED AN ACCEPTANCE OF A PRIOR OFFER BY SELLER, HAC’S ACCEPTANCE IS EXPRESSLY CONDITIONAL ON SELLER’S ASSENT TO THESE TERMS AND CONDITIONS.

2.0  Purchase Order Number

HAC’s Purchase Order number must appear on all invoices, shipping documents, labels and all correspondence and other references thereto. 

3.0  Definitions

The term “Deliverables” means all goods and services to be delivered or provided as specified in this Purchase Order, including by way of example only, all materials and components, design services, automation, manufacturing, installation, inspection, testing and all other materials and labor required to deliver and provide the Deliverables. The term “Loss” means every loss, liability, cost, damage and expense, including attorney’s fees and court costs.

4.0 Time of Performance

Performance of this Purchase Order at the date(s) specified for delivery of the Deliverables is an integral part hereof. Deliverables shall be due no earlier than five (5) days prior to the date specified on the Purchase Order and no later than the date specified on the Purchase order. Seller shall immediately notify HAC in writing of any circumstance, event or occurrence which Seller believes or has reason to believe may result in the inability of Seller to deliver the Deliverables on time.  HAC, at its option, may accept delivery at an earlier or later date or dates, but such acceptance shall not be deemed to waive any right or remedy available to HAC under this Purchase Order.  HAC shall have the right to take discounts on the basis of the date of delivery or the date of receipt of Seller’s invoice, whichever is the latter. If Seller fails to deliver any Deliverables on time, said failure shall constitute a breach, and HAC may, in addition to its other rights and remedies, reject such Deliverables and/or terminate this Purchase Order in whole or in part, and purchase substitute Deliverables elsewhere and charge Seller with any Loss incurred. 

5.0 Delivery; Title; Risk of Loss; Transportation Deliverables shall be delivered FOB at the place or places specified in this Purchase Order by lowest cost transportation unless HAC otherwise directs. Title to and all risks of loss or damage shall remain with Seller until Deliverables are received by HAC.

6.0 Force Majeure

In the event of fire, flood, strike, lockout, other labor disturbances, accident, war or any other cause whatsoever beyond the reasonable control of HAC which prevents or interferes with HAC’s acceptance or use of the Deliverables or the performance of any other obligation of HAC, HAC may defer such acceptance and/or performance without obligation or liability to Seller.

7.0  Quantities; Installment; Count

HAC shall have no obligation to accept or pay for any Deliverables delivered or provided by Seller in excess of that specified in this Purchase Order.  HAC may return excess Deliverables to Seller, and Seller shall reimburse HAC for all costs or expenses incurred by HAC with respect thereto.  If this Purchase Order provides for delivery in multiple installments, Seller’s failure to deliver any installment on time shall constitute a breach.  HAC’s count of Deliverables shall be conclusive unless proven to be manifest error.

8.0  Prices; Invoices

The price for the Deliverables shall be as set forth on the face of this Purchase Order, and payment thereof shall be made in accordance with the applicable provisions of this Purchase Order, or if none are stated, following the completion of all performance obligations of Seller and within sixty (60) days HAC’s receipt of Seller’s invoice. All invoices rendered by Seller shall be in accordance with the instructions on the face of this Purchase Order, accompanied by the original bill of lading or express receipt.  All invoices shall be in duplicate.  Calculations of cash discounts or net payment periods will be made from the date an acceptable invoice is received by HAC.  Seller warrants that the price charged to HAC is not higher than Seller’s price to other buyers for the same or similar Deliverables. 

9.0  Packaging

All Deliverables shall be packed by Seller in suitable containers for protection in shipment and storage. Prices set forth in this Purchase Order include all charges for Seller’s packaging. Items of packaging will not be returned to Seller unless previously agreed to in writing.

All federal, state and local taxes, duties and customs fees are included in the price of the Deliverables stated in this Purchase Order, unless otherwise specified.

11.0  Payment

HAC’s check or draft shall be accepted by Seller in payment under this Purchase Order without discounting for any reason.  Payment will be in United States Dollars, unless otherwise specified.

All warranties, express or implied, shall survive inspection, acceptance and payment.  In the event of Seller’s breach of any such warranty, in addition to other rights and remedies available to HAC, at law or in equity, HAC may return Deliverables for a full refund, or direct Seller to promptly correct the breach by repairing or replacing the applicable Deliverables. HAC reserves the right to repair, alter or modify, at Seller’s cost, Deliverables which fail to conform with the terms, conditions and Specifications of this Purchase Order when the same can be done by HAC at a lesser cost than by returning the Deliverables to Seller. Seller warrants that it has and will convey to HAC good and marketable title to the Deliverables and that all Deliverables are and shall be free from any liens or claims of any other person or entity.

13.0  Acceptance; Inspection

All Deliverables shall be subject to inspection and acceptance or rejection by HAC within a reasonable time after delivery.  Payment for Deliverables shall not be deemed acceptance thereof.  HAC may return to Seller, at Seller’s expense, Deliverables which fail to meet any of the terms, conditions or Specifications of this Purchase Order. HAC shall also have the right of inspection, at its expense, at Seller’s facility at any reasonable time.  No such inspection shall be deemed or construed to be an acceptance of the Deliverables or HAC’s right to inspect the same on delivery as provided above.

14.0  Default; Breach; Negligence; Seller’s Liability

HAC may terminate the Purchase Order or any part thereof for any default or breach, including any failure by Seller to comply with the Purchase Order or any of the these terms and conditions. Seller shall indemnify and hold HAC harmless from and against each and every Loss, including incidental and consequential damages incurred or suffered by HAC which are or are claimed to be in any manner, directly or indirectly, in whole or in part caused, contributed to or occasioned by reason of Seller’s default or breach of any representation, warranty, obligation or covenant of Seller contained in this Purchase Order, or Seller’s performance or failure to perform hereunder, or its negligence whether active or passive, and without limiting its generality, the foregoing shall include injury to or death of any person or persons and damage to or loss of property. HAC shall have the right to cancel this Purchase Order without obligation or liability to Seller in the event of Seller’s breach of any of the terms and conditions hereof or in the event of the institution of any proceedings by or against Seller, voluntary or involuntary, under bankruptcy or insolvency laws, or the appointment of a receiver or trustee or an assignee for the benefit of creditors.  IN NO EVENT SHALL HAC BE LIABLE FOR ANY EXTRAORDINARY, EXEMPLARY, SPECIAL, INDIRECT, CONSEQUENTIAL OR INCIDENTAL DAMAGES OF ANY KIND, INCLUDING WITHOUT LIMITATION, LOST PROFITS, EVEN IF HAC HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

15.0 Changes; Cancellation

In such event, all work completed by Seller hereunder before the giving of such notice, shall be paid for on a percentage of completion basis (subject to acceptance by HAC in accordance with the provisions of this Purchase Order as herein provided).

In the event of any such allegation, claim or charge, HAC may also cancel this Purchase Order without obligation or liability to Seller.
