WARRANTY

MKS Instruments, Inc. (MKS) warrants that the equipment described above (the “equipment”) manufactured by
MKS shall be free from defects in materials and workmanship for a period of one year from date of shipment and
will for a period of two years from the date of shipment, correctly perform all date-related operations, including
without limitation accepting data entry, sequencing, sorting, comparing, and reporting, regardless of the date the
operation is performed or the date involved in the operation, provided that, if the equipment exchanges data or is
otherwise used with equipment, software, or other products of others, such products of others themselves correctly
perform all date-related operations and store and transmit dates and date-related data in a format compatible with
MKS equipment. THIS WARRANTY IS MKS’ SOLE WARRANTY CONCERNING DATE-RELATED
OPERATIONS.
For the period commencing with the date of shipment of this equipment and ending one year later in the case of
defects in materials and workmanship, but two years later in the case of failure to comply with the date-related
operations warranty, MKS will, at its option, either repair or replace any part which is defective in materials or
workmanship or with respect to the date-related operations warranty without charge to the purchaser. The
foregoing shall constitute the exclusive and sole remedy of the purchaser for any breach by MKS of this warranty.
The purchaser, before returning any equipment covered by this warranty, which is asserted to be defective by the
purchaser, shall make specific written arrangements with respect to the responsibility for shipping the equipment
and handling any other incidental charges with the MKS sales representative or distributor from which the
equipment was purchased or, in the case of a direct purchase from MKS, with the MKS home office in Andover,
Massachusetts, USA.
This warranty does not apply to any equipment which has not been installed and used in accordance with the
specifications recommended by MKS for the proper and normal use of the equipment. MKS shall not be liable
under any circumstances for indirect, special, consequential, or incidental damages in connection with, or arising
out of, the sale, performance, or use of the equipment covered by this warranty.
MKS recommends that all MKS pressure and flow products be calibrated periodically (typically every 6 to 12
months) to ensure accurate readings. When a product is returned to MKS for this periodic re-calibration it is
considered normal preventative maintenance not covered by any warranty.
THIS WARRANTY IS IN LIEU OF ALL OTHER RELEVANT WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING THE IMPLIED WARRANTY OF MERCHANTABILITY AND THE IMPLIED WARRANTY OF FITNESS
FOR A PARTICULAR PURPOSE, AND ANY WARRANTY AGAINST INFRINGEMENT OF ANY PATENT.
