Cylinder to Buyer's Product distribution system. Seller will, at Buyer's
expense, remove each Supply System within a reasonable time after the
termination of this Agreement with respect to the Rider covering such Supply
System. Seller may at its expense remove any Supply System or part thereof, and
replace it with another Supply System or part thereof, as Seller may deem

from time to time to shut down each Supply System for such period of time as may
be necessary for repairs and maintenance consistent with proper operation. Each
Supply System or Cylinder will remain the property of Seller at all times. Buyer
will hold harmless Seller from and against liens and claims against each Supply
System or Cylinder due to its location on Buyer's premises.

expiration of such Basic Term. Seller will remove such Supply System provided

Supply System, and (b) in the event that following the removal of such Supply
System Buyer's need for Product resumes at any time within the Basic Term of the
Rider covering such Supply System, such Rider will be reinstated, the Basic Term
of such Rider will be deemed extended by the number of days that such Supply
System was removed from Buyer's Location and Buyer will reimburse Seller for the
cost of reinstalling the Supply System. If Seller relocates, modifies or
replaces all or part of any Supply System due to a change in Buyer's
requirements, method of supply, pressure specifications, Buyer's Location or
Buyer's facilities, Seller may charge Buyer the cost of such relocation,
modification or replacement, adjust the Monthly Service Charge set forth in the
Rider covering such relocated, modified or replaced Supply System, and extend
the term of such Rider effective upon First Delivery to or from the relocated,
modified or replacement Supply System for a period equal to the Basic Term of
such Rider.

all times. Buyer will return each such Cylinder to Seller in a non-contaminated
condition with the cap and any valves and dust plugs tightly closed and with
sufficient residual pressure to prevent contamination to the Cylinder. Buyer
will pay Seller for cleaning any Cylinder if such Cylinder is contaminated when
returned to Seller. Buyer will return each Cylinder to Seller within thirty (30)
days following the termination of this Agreement or pay Seller the

Cylinders and to confirm Buyer's records. Buyer will cooperate with Seller to
protect, locate and recover each Cylinder furnished to Buyer hereunder. Buyer's
obligations under this paragraph will survive the termination of this Agreement.

6. SPECIFICATIONS

      Product delivered hereunder will meet the Specifications. Buyer may reject
any Product which does not meet the Specifications and no charge will be made
for Product so rejected. Since Buyer may obtain devices which have the
capability of testing whether Product meets the Specifications, no claim of any
kind with respect to the conformance of Product to the foregoing Specifications,
whether or not based on negligence, warranty, strict liability or any other
theory of law, will be greater than the price of the quantity of nonconforming
Product in respect to which such claim is made. The foregoing constitutes
Buyer's exclusive remedy and Seller's sole obligation with respect to any such
claim. THERE ARE NO EXPRESS WARRANTIES BY SELLER OTHER THAN THOSE SPECIFIED IN
THIS ARTICLE 6. NO WARRANTIES BY SELLER (OTHER THAN WARRANTY OF TITLE AS
PROVIDED IN THE UNIFORM COMMERCIAL CODE) WILL BE IMPLIED OR OTHERWISE CREATED

MERCHANTABILITY AND WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

      Seller will have the right to adjust the Prices by giving Buyer not less
than fifteen (15) days prior written notice of the effective date of such
adjustment; provided, however, that if said Prices are increased and Buyer,
within fifteen (15) days after said notice, furnishes Seller with credible
written evidence that Buyer can purchase Product to which such increased Prices
apply from a responsible supplier for a specified term in like quantities at
lower prices under similar terms and conditions, and Seller, within fifteen (15)
days thereafter, does not agree to either meet said lower prices or rescind the
notice of increased Prices, Buyer will have the right within ten (10) days
thereafter to terminate this Agreement as to the supply of Product for which
such lower prices are offered by giving Seller not less than ten (10) days prior
written notice. If Buyer exercises such right of termination, the cost of
removal of the Supply System used for the supply of such Product will be borne
by Buyer. If Seller agrees to meet the lower prices or rescind the notice of
increased Prices, Seller may extend the term of the Rider covering such Product
for a period equal to the period of the Basic Term of such Rider. Any
adjustments made by Seller pursuant to this Article 7 with respect to any
Monthly Service Charge or Monthly Rental set forth in the Rider or to surcharges
or other charges which arise pursuant to Article 3 will not be subject to the
proviso contained in the first sentence of this Article 7.

the performance of any of its obligations hereunder (except any obligation to
make payments when due) due

equipment failure, inability to obtain electricity or other type of energy, raw

reasonable control which would make performance commercially impracticable
whether or not the contingency is of the same class as those enumerated above,

however, that neither business downturn nor economic conditions will qualify as
a contingency within the meaning of this Article 8. In the event any such
contingency affects only a part of Seller's capability to produce and/or deliver
Product, Seller will allocate production and/or deliveries among the
requirements of all its affected customers and Seller's own requirements in a
fair and reasonable manner. Buyer will pay or reimburse Seller for any
additional costs incurred relating to the delivery of any Product to Buyer
during a contingency. During any period that delivery of Product is interrupted
or reduced due to a contingency hereunder, the Basic Term will be extended for a
period equal to two (2) times the duration of the contingency.

health information pertaining to Product, including Seller's Material Safety
Data Sheet(s), and Buyer will incorporate such information into Buyer's safety
program. Seller will not be liable to Buyer for any incidental, consequential,
indirect or special damages. Each party hereby indemnifies and holds harmless
the other party from any actions, lawsuits, demands, claims, losses, expenses,
costs (including legal fees) and damages arising from the injury, illness or
death of the indemnifying party's employees in any way related to Product
supplied by Seller under this Agreement, whether or not such injury, illness, or
death is claimed to have been caused by, resulted from, or was in any way
connected with the negligence of the party to be indemnified.

affecting this Agreement, and any other or different terms or conditions in any
purchase orders, Buyer's website agreements (including, without limitation, any
