and in Grainger’s Purchase Order Terms, all of which are incorporated by reference, and all of which are referred to hereinafter

OxySure® Model 615 (Portable Emergency Oxygen System)

Limited Warranty information

October 2011

© OxySure® Systems, Inc. All Rights Reserved Worldwide.

 

Disposable Cartridge: The OxySure® quality limited
warranty lasts for 2 years in the case of the disposable cartridge or until it is used, whichever happens sooner.

 

Reusable Housing: The OxySure® quality limited warranty
lasts for 3 years in the case of the reusable housing or 25 uses, whichever happens first.

 

What will OxySure® do to correct the problem?

 

OxySureR will examine the product and decide, at its sole discretion,
if it’s covered under this limited warranty. OxySure® will then, at its sole discretion, either repair the defective
product or replace it with the same or a comparable product. In these cases, OxySure® will pay for the cost of replacements,
repairs, spare parts, labor and shipping costs, if and where applicable. This does not apply to any repair work or replacement
not expressly authorized by OxySure® in writing. Replacement parts, if any, become the property of OxySure®. If the item
is no longer sold by OxySure®, OxySure® will provide an appropriate replacement. It is OxySure® that, in its sole discretion,
determines what constitutes an appropriate replacement. THIS REMEDY SHALL BE YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY BREACH OF
WARRANTY.

 

Conditions for Limited Warranties:

 

The limited warranties are valid from original
date of acceptance by the end user of the product. The original purchase receipt or purchase order, together with proof of payment
(if applicable) is required as proof of purchase.

 

The limited warranties do not apply to normal wear and tear
of products or to products that have been stored or shipped incorrectly, including storage or shipment under environmental conditions
outside of those conditions specified by OxySure®. Furthermore, the limited warranties do not apply to products that have been
used inappropriately, abused, misused, altered, or cleaned with incorrect cleaning methods or incorrect cleaning products. The
limited warranties do not cover normal wear and tear, cuts or scratches, or damage caused by impacts or accidents. The limited
warranties do not cover defects in appearance, cosmetic, decorative items or any non-operative parts. The limited warranties do
not apply if the product serial number has been removed, defaced or altered. Further, the limited warranties are not applicable
if the products have been stored outdoors or in humid environments, or if the products have been otherwise not stored at room temperature.

 

Warranty coverage terminates if the original purchaser sells
or otherwise transfers the product, unless the original purchaser is an authorized distributor of OxySure® products; in such
event, coverage is transferred to the original customer of such distributor (the “end user”). Warranty coverage also
terminates if the end user sells or otherwise transfers the product. No OxySure® reseller, agent, or employee is authorized
to make any modification, extension, or addition to this warranty.

 

    	 

    	 

    

 

Some states and provinces do not allow the limitation or exclusion
of incidental or consequential damage, so this limitation may not apply to you.

 

Care instructions:

 

To be able to claim the limited warranty you need to follow
the specific instructions for the products, including, but not limited to, the “Instructions for Use”.

 

How country, provincial and state law applies:

 

This limited warranty gives you specific legal rights, and you
may also have other rights that vary from country to country, state to state or province to province.

 

Procedure for Claims Under Limited Warranties:

 

No product may be returned directly to OxySure® without
first contacting OxySure® for a Return Material Authorization ("RMA") number. If it is determined that the product
may be defective, you will be given an RMA number and instructions for product return. An unauthorized return, i.e. one for which
an RMA number has not been issued, may be returned to you at your expense. Authorized returns are to be shipped prepaid and insured
to the address on the RMA in an approved shipping container. Your original box and packaging materials should be kept for storing
or shipping your product. To obtain warranty service, an original purchase receipt or purchase order, together with proof of payment
(if applicable) is required as proof of purchase. OxySure® retains the exclusive right to either repair or replace the unit
at its sole discretion.

 

Please complete these two easy steps:

 

  STEP 1: Contact OxySure® Customer Service to receive
a RMA number.

 

Call or e-mail OxySure® Customer Service to describe the
problem you are experiencing and request a RMA number. You will need to provide the product’s serial number (if applicable),
your return shipping address, and a daytime telephone number.

Phone: 1-888-7OXY-SURE

E-mail: service@oxysure.com

 

  STEP 2: Ship the unit, along with the RMA number, to OxySure®.

 

Once you have received the RMA number, securely package the
product and ship it (insured) to the following address:

OxySure Systems, Inc.

Attn: Customer Service

10880 John W. Elliott Road,
Suite 600

Frisco, Texas 75033 USA

RMA Number: (insert your RMA number here - see above)
