Starbucks Limited Warranty
Overview: All sales by Structural Concepts Corporation (hereafter referred to
as “Structural Concepts”) are subject to the following limited warranty.
“Goods” refers to the product or products being sold by Structural Concepts.
Warranty Scope: Warranty is for equipment sold ONLY to Starbucks Corporation
and its licensees in the United States, Canada, Mexico and Puerto Rico.
Equipment sold elsewhere may carry modified warranties. Warranty; Remedies;
Limitations: Limit of liability of Structural Concepts toward the exchange
cost of the original compressor motor (and/or any other components) is one
year parts and labor. If any Goods are found to be of faulty material or
workmanship within one year of the original F.O.B. (free on board) unit
shipment, Structural Concepts will, at its option (after inspection by an
authorized representative), replace or pay the reasonable cost of replacement
of the faulty Goods. If warranty claim is not made within this one year time
period, Structural Concepts is not bound to warrant Goods. A motor-compressor
(and/or any other components) replaced during the warranty shall not exceed
manufacturer’s current established wholesaler’s exchange price. If replacement
motor-compressor (and/or other components) is available via storage facility,
parts truck, etc., Structural Concepts mandates that readily accessible
replacement components be used toward repair of Goods; in such instances,
Structural Concepts will replace such equipment (at its own expense) after
confirmation of its use/placement on defective unit. Structural Concepts shall
not be charged an additional fee, up-charge or expense for such replacement
Goods. If Structural Concepts is unable to repair or replace the defective
Goods, Structural Concepts shall issue a credit to the Purchaser for full or
partial purchase price, as Structural Concepts shall determine. The
replacement or payment in the manner described above shall be the sole and
exclusive remedy to Purchaser for a breach of this warranty. If any Goods are
defective or fail to conform to this warranty, Structural Concepts will
furnish instructions for their disposition. No Goods shall be returned to
Structural Concepts without its prior consent. Structural Concepts’ liability
for any defect in the Goods shall not exceed the purchase price of the Goods.
Structural Concepts SHALL HAVE NO LIABILITY TO PURCHASE FOR CONSEQUENTIAL
DAMAGES OF ANY KIND WHATSOEVER, INCLUDING, BUT NOT LIMITED TO, PERSONAL
INJURY, PROPERTY DAMAGE, LOST PROFITS, OR OTHER ECONOMIC INJURY DUE TO ANY
DEFECT IN THE GOODS OR ANY BREACH OF Structural Concepts, Structural Concepts
SHALL NOT BE LIABLE TO THE PURCHASER IN TORT FOR ANY NEGLIGENT DESIGN OR
MANUFACTURE OF THE GOODS, OR FOR THE OMISSION OF ANY WARNING THEREFROM.
Structural Concepts shall have no obligation or liability under this warranty
for claims arising from any other party’s (including Purchaser’s) negligence
or misuse of the Goods or environmental conditions. This warranty does not
apply to any claim or damage arising for or cause by improper storage,
handling, installation, maintenance, or from fire, flood, accidents,
structural defects, building settlement or movement, acts of God, or other
causes beyond Structural Concepts’ control. Except as expressly stated herein,
Structural Concepts makes no warranty, express, implied, statutory or
otherwise as to any parts or goods not manufactured by Structural Concepts.
Structural Concepts shall warrant such parts or Goods only (I) against such
defects, (II) for such periods of time, and (III) with such remedies, as are
expressly warranted by the manufacturer of such parts of Goods.
Notwithstanding the foregoing, any warranty with respect to such parts of
Goods and any remedies available as a result of a breach thereof shall be
subject to all of the procedures, limitations, and exclusions set forth
herein. THE WARRANTIES HEREIN ARE IN LIEU OF ALL WARRANTIES, EXPRESS, IMPLIED,
STATUTORY, OR OTHERWISE. IN PARTICULAR, Structural Concepts MAKES NO WARRANTY
OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. No representative,
agent or dealer of Structural Concepts has authority to modify, expand, or
extend this Warranty, to waive any of the limitations or exclusions, or to
make any different or additional warranties with respect to Goods. Period of
Limitations: No claim, suit or other proceeding may be brought by Purchaser
for any breach of the foregoing warranty or this Agreement by Structural
Concepts or in any way arising out of this Agreement or relating to the Goods
after one year from the date of the breach. In the interpretation of this
limitation on action for a breach by Structural Concepts, it is expressly
agreed that there are no warranties of future performance of the goods that
would extend that period of limitation herein contained for bringing an
action. Indemnifications: Purchaser agrees to indemnify, hold harmless, and
defend Structural Concepts if so requested, from any and all liabilities, as
defined herein, suffered, or incurred by Structural Concepts as a result of,
or in connection with, any act, omission, or use of the Goods by Purchaser,
its employees or customers, or any breach of this Agreement by Purchaser.
Liabilities shall include all costs, claims, damages, judgments, and expenses
(including reasonable attorney fees and costs). Remedies of Structural
Concepts: Structural Concepts’ rights and remedies shall be cumulative and may
be exercised from time to time. In a proceeding or action relating to the
breach of this Agreement by Purchaser, Purchaser shall reimburse Structural
Concepts for reasonable costs and attorney’s fees incurred by Structural
Concepts. No waiver by Structural Concepts of any breach of Purchaser shall be
effective unless in writing nor operate as a waiver of any other breach of the
same term thereafter. Structural Concepts shall not lose any right because it
has not exercised it in the past. Applicable Law. This Agreement is made in
Michigan and shall be governed by and interpreted according to Michigan law.
Any lawsuit arising out of this Agreement or the Goods may be handled by a
federal or state court whose district includes Muskegon County, Michigan, and
Purchaser consents that such court shall have personal jurisdiction over
Purchaser. Miscellaneous: If any provision of this Agreement is found to be
invalid or unenforceable under any law, the provision shall be ineffective to
that extent and for the duration of the illegality, but the remaining
provisions shall be unaffected. Purchaser shall not assign any of its rights
nor delegate any of these obligations under this Agreement without prior
written consent of Structural Concepts. This Agreement shall be binding upon
and inure to the benefit of Structural Concepts and Purchaser and each of
their legal representatives, successors and assignees. Structural Concepts
warrants its products to be free of defects in materials and workmanship under
normal use and service for a period of one (1) year. This warranty is extended
only to the original purchaser for use of the Goods. It does not cover normal
wear parts such as plastic tongs, tong holders, tong cables, bag holders, or
acrylic dividers. General Conditions: All service labor and/or parts charges
are subject to approval by Structural Concepts. Contact Customer Service Dept.
in writing, by phone, fax or email. All claims must contain the following
information: (1) model & serial code number of equipment; (2) the date and
place of installation; (3) the name and address of the agency which performed
the installation; (4) the date of the equipment failure; and (5) a complete
description of the equipment failure and all circumstances relating to that
failure. Once the claim has been determined to be a true warranty claim by
Structural Concepts’ Customer Service Department, the following procedure will
be taken: (1) replacement parts will be sent at no charge from Structural
Concepts on a freight prepaid basis; (2) reimbursement for service labor will
be paid if the following conditions have been met – (a) prior approval of
service agency was awarded from the Customer Service Department; and (b) an
itemized statement of all labor charges incurred is received by the Customer
Service Department. The cost of the service labor reimbursement will be based
on straight time rates and reasonable time for the repair of the defect. If
problems occur with any compressor, notify Structural Concepts’ Customer
Service Department immediately. Any attempt to repair or alter the unit
without prior consent from the Customer Service Department may render any
warranty claim null and void. This warranty and protection plan does not apply
to any condensing unit or any part thereof which has been subject to accident,
negligence, misuse, or abuse, or which has not been operated in accordance
with the manufacturer’s recommendations or if the serial number of the unit
has been altered, defaced, or removed. One Year Limit of Liability: After
Structural Concepts’ one-year parts and labor warranty on the original F.O.B.
(free on board) unit has expired, Structural Concepts is not liable for either
the equipment or labor costs of repairing or replacing the motor compressor,
nor any other components that were included in the original F.O.B. (free on
board) unit.
