Amendment
No. 1

This
Amendment Number 1 (the “Amendment”)
is made
as of the 30th day of January 2004 by and between Air Products and Chemicals,
Inc. (“Buyer”),
and Keyes
Helium Company, LLC (“Seller”).

Whereas, Buyer
and Seller are parties to that Contract for Sale and Purchase of Liquid Helium
as Amended and Restated dated as of 1 January 1999 (the “Original
Contract”), under
which Seller is obligated to sell to Buyer, and Buyer is obligated to purchase
from Seller, all liquid helium processed at Seller’s Facility (as defined in the
Original Contract) (capitalized terms used in this letter agreement but not
defined herein shall have the meanings given them in the Original Contract);
and

Whereas, Seller
is currently contemplating upgrades and repairs to Seller’s Facility, which
repairs and upgrades, if undertaken, would be provided by Buyer under a separate
contract for the compensation rates stated therein; and

Whereas, the
parties now desire to make certain amendment to the Original Contract to provide
for the sale of crude helium by Seller to Buyer, to amend the price re-openers,
to facilitate payments for said repairs and upgrades to Seller’s Facility, and
make certain other changes.

Now Therefore,
in
consideration of the mutual promises of the parties set forth below and for
other for good and valuable consideration, the receipt of which is hereby
acknowledged, Buyer and Seller, intending to be legally bound, hereby agree as
follows:

1. Amendments
to Original Agreement. The
Original Agreement is hereby amended as follows:

(a) Article 1
is hereby amended to add the following definitions are added in the correct
alphabetical location:

“Capacity
Limitation Crude”
means
crude helium owned by Seller

in excess
of that, which can be refined at Seller’s Facility as set forth in the

Original
Agreement Article 2.3 as the capacity limitation.

“Facility
Services Agreement”
means the
contract entered into by Seller and Buyer under which Buyer, during calendar
year 2004, provides various upgrade and upgrade parts and services for Seller’s
Facility for a fee.

 

“Facility
Services Fee” means the
total amount payable by Seller to Buyer under the Facility Services Agreement,
whether for fees, expenses or otherwise.

“Keyes
Crude” means,
collectively, the Capacity Limitation Crude and the Outage Crude and Shutdown
Crude, if any.

“Outage
Crude” means
crude helium owned by Seller that would typically be refined at Seller’s
Facility pursuant to Article 2 but cannot be due to Seller’s Facility’s
undergoing upgrades and repairs, including the Upgrades.

“Reimbursement
Period” means the
period of time in which Seller is required to reimburse Buyer for the Facility
Service Fee, as set forth in Section 5.8.

“Shutdown Crude”
is
defined in Section 4.3.1.

“Upgrades” meaning
the improvements and repairs that are to be made to Seller’s Facility in
calendar year 2004 under separate contract between Seller, as purchaser, and
Buyer, as provider, of the upgrade and repair services.”

	
      (b)
	
      Article
      4 is hereby amended to add the following new Sections to the end of
      such

Article:

“4.3
Crude
Helium Sales. Keyes
hereby agrees to sell to APCI, and APCI hereby agrees to purchase from Keyes,
for the applicable Crude Helium Price set forth in Section 5.7, all
Outage Crude and all Capacity Limitation Crude. All Outage Crude sold hereunder
shall constitute “Sales Volumes” for purposes hereof. All deliveries of Keyes
Crude shall be FOB the BLM System or if the BLM System is unavailable, into
Buyer’s tube trailer at Seller’s Facility. Seller will provide Buyer, through
the BLM System, 1.02 units of Crude Helium for each unit of Liquid Helium
delivered into Buyer’s container from Keyes Crude.

4.3.1 If
Seller at any time shuts down and does not restart Seller’s Facility, Buyer
shall be entitled to purchase Crude Helium from Seller in amounts equivalent to
that required to produce 160 MMcf per year of Liquid Helium (the “Shutdown
Crude”). The
purchase price for Shutdown Crude will equal the following:

 

 

 

	
      Up
      to and including 70 MMcf (Tier I volume)
	
      [***]

	
      Greater
      than 70 MMcf (Tier II volume)
	
      [***]

The
Parties’ obligations with respect to Capacity Limitation Crude shall not be

affected
by this Section 4.3.1, and shall continue as set forth in Section
4.1.

 

4.4
Security
for Facility
Services Fee Payment and Crude Helium Sales To
secure Seller’s obligations to Buyer hereunder, Seller hereby grants a
continuing security interest to Buyer in all Crude Helium Seller purchases under
contract from any seller of natural gas that contains Helium, whether or not
such Helium is to be processed, and if so, whether or not by Seller or by
another processor. Seller shall execute all documents, UCC filings and other
instruments and shall make all filings necessary or appropriate to make, perfect
and continue this security interest.”

(c)  Article
5 is hereby amended by adding the following Sections to the end of such
Article:

      During
      Weeks 9-12

	
      [***]
	
      From
      and After Week 13

The
metric for defining the applicable tier pricing window shall be Buyer’s repair
work completion exclusively on the helium purifier/liquefier cold box. Outage
Crude shall be additive to the Refined Helium volumes and contribute in the
calculation of APCI’s volume obligations for tier pricing
adjustments.

5.7.2 The
purchase price for Capacity Limitation Crude shall equal [***], which
price shall be escalated [***] each
year; provided, however, that the price for Capacity Limitation Crude shall be
subject to renegotiation effective 1 January 2009 and on each five
(5)-year anniversary
thereof, upon Notice by either Party to the other, given not later than fifteen
(15) months
prior to the 1 January on which the new price is to take effect. If the Parties
are unable to reach agreement prior to the 1 October immediately preceding the
date on which the new price is to take effect, after having conducted good-faith
negotiations with respect to the modification of the then-current price of
Capacity Limitation Crude, either Party shall have the right to terminate the
provisions of this Agreement that address the sale of Capacity Limitation Crude
by Seller to Buyer, but such termination shall not affect any other provision,
or terminate any other obligation, of this Agreement.

Services Fee Payment. If the
Parties have entered into the Facility Services Agreement and Seller elects to
make payment of the Facility Services Fee by delivery of Helium to Buyer, Buyer
agrees to accept payment thereunder in accordance with the following
schedule:

      No

      [********]
	
      Parties
      to discuss

Buyer
shall receive a reimbursement payment or credit equivalent to [***]
purchased by Buyer hereunder until all amounts owed by Seller to Buyer under the
Facility Services Agreement have been paid to Buyer. Seller shall elect to
handle the credit by (i) deducting the amount of the credit from the invoice
presented to Buyer or (ii) making a cash payment within fifteen (15) days of
the end of each month for which the credit is due of the amount of the credit
calculated for such month. Seller may, at any time, elect to make a lump sum
cash payment for the full, unpaid portion of the Facility Services Fee, at which
point Buyer’s credit under this Section 5.8 would end; provided however, that if
for any reason such lump sum payment was required to be returned to Seller or
another person, Buyer would have the right to restart the credit to recoup the
Facility Services Fee. Further, in the event that Seller is constrained from
processing feedstock volumes through no fault of its own, which precludes it
from meeting its payment obligations within the prescribed timeframe, Seller and
Buyer shall meet and negotiate in good faith a mutually acceptable payment
program to address any payment shortfalls. During such good faith negotiation,
Seller shall not be subject to claims of breach or default; provided, however
the negotiations shall not extend beyond forty-five (45) days.”

(d) Section
5.6 is hereby
amended to extend the dates “1 January 2009” and “1 January 2014,” and each
related Notice and negotiation date previous thereto, by an amount of time equal
to the Reimbursement Period.

2. Confirmation.
Except as
expressly set forth herein, all of the terms and conditions of the Original
Agreement shall remain unchanged and continue to be in full force and effect and
are hereby ratified and confirmed by Seller and Buyer.

3. Counterparts. This
Amendment may be executed in any number of counterparts, and by different
parties hereto in separate counterparts, each of which when so executed and
delivered shall be deemed an original, but all such counterparts together shall
constitute but one and the same instrument.

4. Governing
Law. This
Amendment, both as to interpretation and performance, shall be governed by the
laws of the State of Colorado without giving effect to its conflict of law
provisions.

81/2% SENIOR SUBORDINATED NOTE DUE 2015  

 Principal and Interest; Subordination.  

        The Company will pay the principal of this Note on February 1, 2015. 

        The
Company promises to pay interest and Special Interest, if any, on the principal amount of this Note on each Interest Payment Date, as set forth below, at the rate of
81/2% per annum (subject to
adjustment as provided below) except that interest accrued on this Note pursuant to the fourth paragraph of this Section 1 for periods prior to the applicable dates on which the Exchange Offer
Registration Statement or Shelf Registration Statement (as such terms are defined in the Registration Rights Agreement referred to below) will accrue at the rate or rates borne by the Notes from time
to time during such periods. 

        Interest,
and Special Interest, if any, will be payable semi-annually (to the Holders of record of the Notes (or any predecessor Notes) at the close of business on
February 1 or August 1 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing August 1, 2005. 

        The
Holder of this Note is entitled to the benefits of the Registration Rights Agreement, dated January 31, 2005, among the Company, the Guarantors and the Initial Purchasers
named therein (the "Registration Rights Agreement"). 

        Interest
on this Note will accrue from the most recent date to which interest has been paid on this Note or the Note surrendered in exchange herefor or, if no interest has been paid,
from January 31, 2005; provided that, if there is no existing default in the payment of interest and if this Note is authenticated between a
Regular Record Date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a
360-day year of twelve 30-day months. 

        The
Company shall pay interest and Special Interest if any, on overdue principal and premium, if any, and interest on overdue installments of interest, to the extent lawful, at a rate
per annum equal to the rate of interest applicable to the Notes. 

        The
indebtedness evidenced by the Notes is, to the extent and in the manner provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness, and this Note is issued subject to such provisions. Each Holder of this Note, by accepting the same, (a) agrees to and shall be bound by such provisions,
(b) authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in the Indenture and (c) appoints
the Trustee its attorney in-fact for such purpose. 

 Method of Payment.  

        The Company will pay interest (except defaulted interest) on the principal amount of the Notes on each February 1 and August 1 to the Persons who
are Holders (as reflected in the Note Register at the
close of business on January 15 and July 15 immediately preceding the Interest Payment Date), in each case, even if the Note is cancelled on registration of transfer or registration of
exchange after such Regular Record Date; provided that, with respect to the payment of principal, the Company will make payment to the Holder that
surrenders this Note to any Paying Agent on or after February 1, 2015. 

        The
Company will pay principal (premium, if any) and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. However,
the Company may pay principal (premium, if any) and interest by its check payable in such money. The Company may pay interest on the Notes either (a) by mailing a check for such interest to a
Holder's registered address (as reflected in the Note Register) or (b) by wire transfer to an account located in the United States maintained by the payee. If a payment date is a date other
than a Business Day at a place of payment, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period. 

 Paying Agent and Note Registrar.  

        Initially, The Bank of New York Trust Company, N.A., a national banking association (the "Trustee"), will act as Paying Agent and Note Registrar. The Company may
change any Paying Agent or Note Registrar upon written notice thereto. The Company, any Subsidiary or any Affiliate of any of them may act as Paying Agent, Note Registrar or co-registrar. 

 Indenture.  

        The Company issued the Notes under an Indenture dated as of January 31, 2005 (the "Indenture"), among the Company, the Guarantors and the Trustee.
Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by
applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control. 

        The
Notes are unsecured senior obligations of the Company. The Indenture does not limit the aggregate principal amount of the Notes. 

 Redemption.  

        Optional Redemption.    At any time on or prior to February 1, 2010, the Company may redeem all or a part of the Notes,
upon not less than 30 nor more than 60 days' prior notice mailed by first-class mail to each Holder's registered address, at a redemption price equal to 100% of the principal amount of Notes
redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Special Interest, if any, to the Redemption Date, subject to the rights of Holders of Notes on the relevant record date
to receive interest due on the relevant interest payment date. 

        On
and after February 1, 2010, the Company may redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days' prior notice by first class mail, postage
prepaid, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the Note Register at the Redemption Prices (expressed as percentages of principal amount) set
forth below, plus accrued and unpaid interest thereon and Special Interest, if any, to the applicable Redemption Date, subject to the right of Holders of record on the relevant Record Date to receive
interest due on the relevant Interest Payment Date, if redeemed during the twelve-month period beginning on February 1 of each of the years indicated below: 

	Year
 
	 	Percentage
	 
	2010	 	104.250	%
	2011	 	102.833	%
	2012	 	101.417	%
	2013 and thereafter	 	100.000	%

        In
addition, until February 1, 2008, the Company may, at its option, redeem up to 40% of the aggregate principal amount of Notes issued under the Indenture at a redemption price
equal to 108.500% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon and Special Interest, if any, to the applicable Redemption Date, subject to the right of Holders
of record on the relevant record date to receive interest due on the relevant interest payment date, with the net proceeds of one or more Equity Offerings;  provided that at least 60% of the sum of the
aggregate principal amount of Notes originally issued under the Indenture remains outstanding immediately
after the occurrence of each such redemption; provided further that each such redemption occurs within 90 days of the date of closing of each
such Equity Offering. 

 Repurchase upon a Change of Control and Asset Sales.  

        Upon the occurrence of (a) a Change of Control, unless the Company has elected to redeem the Notes in connection with such Change of Control, the Holders
of the Notes will have the right to require that the Company purchase such Holder's outstanding Notes, in whole or in part, at a purchase price of 101% of the principal amount thereof, plus accrued
and unpaid interest and Special Interest, if any, to the date of purchase, subject to the right of Holders of record on the relevant record date to receive interest on the relevant interest payment
date and (b) Asset Sales, the Company may be obligated to make offers to purchase Notes and Pari Passu Indebtedness of the Company with a portion of the Net Proceeds of such Asset Sales at a
redemption price of 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase. 

 Denominations; Transfer; Exchange.  

        The Notes are in registered form without coupons in denominations of $2,000 principal amount and whole multiples of $1,000 in excess thereof. A Holder may
transfer or exchange Notes in accordance with the Indenture. The Note Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any
taxes and fees required by law or
permitted by the Indenture. The Note Registrar need not register the transfer or exchange of any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the
Note not to be redeemed) or any Notes for a period of 15 days before a selection of Notes to be redeemed or 15 days before an interest payment date. 

 Persons Deemed Owners.  

        A registered Holder may be treated as the owner of a Note for all purposes. 

 Unclaimed Money.  

        If money for the payment of principal (premium, if any) or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to
the Company at its written request. After that, Holders entitled to the money must look to the Company for payment, unless an abandoned property law designates another Person, and all liability of the
Trustee and such Paying Agent with respect to such money shall cease. 

 Discharge and Defeasance Prior to Redemption or Maturity.  

        If the Company irrevocably deposits, or causes to be deposited, with the Trustee money or Government Securities sufficient to pay the then outstanding principal
of (premium, if any) and accrued interest on the Notes (a) to Redemption Date or Maturity, the Company will be discharged from its obligations under the Indenture and the Notes, except in
certain circumstances for certain covenants thereof, and (b) to the Stated Maturity, the Company will be discharged from certain covenants set forth in the Indenture. 

 Amendment; Supplement; Waiver.  

        Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate
principal amount of the Outstanding Notes, and any existing Default or Event of Default or compliance with any provision may be waived with the consent of the Holders of not less than a majority in
aggregate principal amount of the Outstanding Notes. Without notice to or the consent of any Holder, the parties thereto may amend or supplement the Indenture or the Notes to, among other things, cure
any ambiguity, omission, mistake, defect or inconsistency and make any change that does not adversely affect the rights of any Holder. 

 Restrictive Covenants.  

        The Indenture contains certain covenants, including covenants with respect to the following matters: (i) Restricted Payments; (ii) Incurrence of
Indebtedness and Issuance of Disqualified Stock; (iii) Liens; (iv) transactions with Affiliates; (v) dividend and other payment restrictions affecting Restricted Subsidiaries;
(vi) guarantees of Indebtedness by Restricted Subsidiaries; (vii) incurrence of other Pari Passu Indebtedness; (viii) merger and certain transfers of assets; (ix) purchase
of Notes upon a Change in Control; and (x) disposition of proceeds of Asset Sales. Within 120 days (or the successor time period then in effect under the rules and regulations of the
Exchange Act) after the end of each fiscal year, the Company must report to the Trustee on compliance with such limitations. 

 Successor Persons.  

        When a successor Person or other entity assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor Person will be released
from those obligations. 

 Remedies for Events of Default.  

        If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 30% in principal amount of the Outstanding
Notes may declare all the Notes to be immediately due and payable; provided, however, that, so long as any Indebtedness permitted to be incurred under
the Indenture as part of the Senior Credit Facilities shall be outstanding, no such acceleration shall be effective until the earlier of (1) acceleration of any such Indebtedness under the
Senior Credit Facilities, or (2) five Business Days after the giving of written notice of such acceleration to the Company and the Bank Agent. If a bankruptcy or insolvency default with respect
to the Company or any of its Significant Subsidiaries occurs and is continuing, the Notes automatically become immediately due and payable. Subject to the provisions of the Indenture relating to the
duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any rights or powers under the Indenture at the request or direction
of any of the Holders of the Notes unless such Holders have offered to the Trustee reasonable indemnity satisfactory to it against any cost, liability or expense. Subject to certain restrictions, the
Holders of not less than a majority in principal amount of the Outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or any Guarantee or that the
Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee in personal liability. 

 Guarantees.  

        The Company's obligations under the Notes are fully, irrevocably and unconditionally guaranteed on an unsecured senior subordinated basis, to the extent set forth
in the Indenture, by each of the Guarantors. 

 Trustee Dealings with Company.  

        The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may make loans to, accept deposits from,
perform services for, and otherwise deal with, the Company and its Affiliates as if it were not the Trustee. 

 Authentication.  

        This Note shall not be valid until the Trustee signs the certificate of authentication on the other side of this Note. 

 Abbreviations.  

        Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN
(= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts to Minors Act). 

 CUSIP Numbers.  

        Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the
Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the
Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 

 Holders' Compliance with the Registration Rights Agreement.  

        Each Holder of a Note, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations of the
Holders with respect to a registration and the indemnification of the Company to the extent provided therein.

        THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

        The
