                     SECTION 3. PURCHASE PRICE; ADJUSTMENT

         3.1      Purchase Price.

                  (a)      Closing Date Payment. The Purchaser agrees to pay to
the Seller on the Closing Date an amount equal to $175,000,000 (the "Closing
Date Payment") as payment for the Purchased Assets and to assume the Assumed
Liabilities pursuant to Section 2.3 hereof (the amount of the Closing Date
Payment, as increased, if at all, by the amount of the Post-Closing Payment
pursuant to Section 3.2, being referred to herein as the "Purchase Price"). The
Purchase Price shall be exclusive of all applicable sales, goods and services,
value added, transfer and similar Taxes incurred with respect to the transfer of
the Purchased Assets.





                                                                              29

                  (b)      The Closing Date Payment shall be made by the
Purchaser to the Seller in immediately available funds by wire transfer to such
account as the Seller shall designate in writing at least three (3) Business
Days prior to the Closing Date.

         3.2      Post-Closing Payment.

                  (a)      Delivery of Post-Closing Payment Statement. On the
Post-Closing Payment Date, the Purchaser shall deliver to the Seller (i) the
Post-Closing Payment and (ii) a statement (the "Post-Closing Payment Statement")
setting forth its calculation of the amount of the Post-Closing Payment,
together with its determination of the amount of the Annualized Post-Integration
EBITDA and of the Targeted EBITDA. The Annualized Post-Integration EBITDA and
the Targeted EBITDA shall be calculated in accordance with the Post-Closing
Payment Methodology. The Post-Closing Payment shall be made by the Purchaser to
the Seller in immediately available funds by wire transfer to such account as
the Seller shall designate in writing at least three (3) Business Days prior to
the Post-Closing Payment Date.

                  (b)      Post-Closing Payment. The amount of the post-closing
payment (the "Post-Closing Payment") shall be calculated as follows:

                           (i)      in the event that the Annualized
Post-Integration EBITDA exceeds the Targeted EBITDA (as set forth in the
Post-Closing Payment Statement) (the amount of such excess, the "Excess
Post-Integration EBITDA Amount"), then the Post-Closing Payment shall be an
amount equal to the lesser of (I) the product of (x) the Excess Post-Integration
EBITDA Amount and (y) six (6) and (II) $25,000,000; and

                           (ii)     in the event that the Annualized
Post-Integration EBITDA is less than or equal to the Targeted EBITDA (as set
forth in the Post-Closing Payment Statement) (a "Post-Integration Deficit EBITDA
Event"), then the Post-Closing Payment shall be equal to zero ($0).

                  (c)      Objection to Post-Closing Payment Statement. The
Seller may dispute the amounts set forth on the Post-Closing Payment Statement,
but only on the basis that the Purchaser's determination of the amount of the
Annualized Post-Integration EBITDA or Targeted EBITDA was not calculated in a
manner substantially consistent with the Post-Closing Payment Methodology;
provided, that the Seller shall have notified the Purchaser in writing (the
"Objection Notice") within thirty (30) days after receiving the Post-Closing
Payment Statement, specifying the amount thereof in dispute and setting forth in
reasonable detail the basis for the dispute, including reasonable details of its
calculations.

                  (d)      Resolution of Disputes. The Purchaser shall give the
Seller and its independent public accountants reasonable access to the
Purchaser's work papers used in the preparation of the Post-Closing Payment
Statement to enable the Seller to exercise its rights under this Section 3.2.
The Seller and the Purchaser shall attempt in good faith to resolve all of the
items in dispute set out in the Objection Notice within thirty (30) days of
receipt of the Objection Notice by the Purchaser. Any items in dispute not
resolved within such thirty (30) day period shall be referred as soon as
possible thereafter by the Seller and the Purchaser to the Independent
Accountant. The parties shall require the Independent Accountant (i) to act as
an





                                                                              30

expert and not as an arbitrator, (ii) to determine the items in dispute that
have been referred to it as soon as reasonably practicable but in any event not
later than thirty (30) days after the date of referral of the dispute to it, and
(iii) in making its determination, to consider only the issues in dispute placed
before it and to base its determination on the application of the Post-Closing
Adjustment Methodology. The Seller and the Purchaser shall provide or make
available all documents and information as are reasonably required by the
Independent Accountant to make its determination. The determination of the
Independent Accountant as to all items in the Post-Closing Payment Statement and
the resulting calculation of the Annualized Post-Integration EBITDA and the
Targeted EBITDA shall be final and binding on the parties.

                  (e)      Independent Accountant Expenses. The fees and
expenses of the Independent Accountant in acting in accordance with this Section
3.2 shall be shared equally by the Purchaser and the Seller.

                  (f)      Final Post-Closing Payment Statement. The
Post-Closing Payment Statement shall be deemed final and binding upon the
parties upon the earliest of: (i) the failure of the Seller to notify the
Purchaser of its objection within thirty (30) days after receiving the
Post-Closing Payment Statement, (ii) the resolution of all disputes that are the
subject of an Objection Notice by the parties, or (iii) the final determination
of the Independent Accountant. The amount, if any, by which the Annualized
Post-Integration EBITDA exceeds the Targeted EBITDA as set forth in the final
Post-Closing Payment Statement shall be deemed the "Final Excess
Post-Integration EBITDA Amount."

                  (g)      Payment of Final Purchase Price Adjustment. Within
three (3) Business Days after the Post-Closing Payment Statement being deemed
final and binding on the parties in accordance with Section 3.2(f), if the Final
Excess Post-Integration EBITDA is greater than or less than the Excess
Post-Integration EBITDA, or if a Post-Integration Deficit EBITDA Event had
occurred but a Final Excess Post-Integration EBITDA Amount is determined, an
adjustment to the amount of the Post-Closing Payment shall be made as follows:

                           (i)      in the event that the Final Excess
Post-Integration EBITDA Amount exceeds the Excess Post-Integration EBITDA
Amount, then the Post-Closing Payment shall be adjusted upward in an amount
equal to the lesser of (A) the product of (x) the excess of the Final Excess
Post-Integration EBITDA Amount over the Excess Post-Integration EBITDA Amount
and (y) six (6) and (B) the difference of (x) $25,000,000 less (y) the amount,
if any, previously paid to the Seller as the Post-Closing Payment pursuant to
Section 3.2(b), and the Purchaser shall pay to the Seller such amount in
immediately available funds by wire transfer to such account as the Seller shall
designate in writing to the Purchaser;

                           (ii)     in the event that a Post-Integration Deficit
EBITDA Event had occurred and the initial Post-Closing Payment had been equal to
zero ($0), then the Post-Closing Payment shall be adjusted upward in an amount
equal to the lesser of (I) the product of (x) the Final Excess Post-Closing
Integration EBITDA Amount and (y) six (6) and (II) $25,000,000, and the
Purchaser shall pay to the Seller such amount in immediately available funds by
wire transfer to such account as the Seller shall designate in writing to the
Purchaser; and





                                                                              31

                           (iii)    in the event that the Excess
Post-Integration EBITDA Amount exceeds the Final Excess Post-Integration EBITDA
Amount, then the amount of the Post-Closing Payment shall be adjusted downward
in an amount equal to the product of (x) the amount of such excess and (y) six
(6); provided, that such amount shall not exceed the amount, if any, paid to the
Seller as the Post-Closing Payment pursuant to Section 3.2(b), and the Seller
shall pay to the Purchaser such amount in immediately available funds by wire
transfer to such account as the Purchaser shall designate in writing to the
Seller.

                  (h)      Notwithstanding anything to the contrary in this
Section 3.2, if at any time prior to the Post-Closing Payment Statement being
deemed final and binding in accordance with Section 3.2(f), a Change of Control
Transaction occurs with respect to the Purchaser pursuant to subsection (ii) of
the definition of Change of Control Transaction, then either (I) the acquiror in
such transaction shall agree in writing with the Seller (in form and substance
reasonably satisfactory to the Seller) to maintain the ability to track the
financial performance of the business of the Purchaser to allow such acquiror to
make the calculations that are required pursuant to this Section 3.2, in which
case the provisions of this Section 3.2 shall apply to the determination of the
amount of the Post-Closing Payment by any such acquiror; provided, that in
connection with the resolution of any dispute pursuant to Section 3.2(d), such
acquiror shall also give to the Seller, the Seller's independent public
accountants (the "Seller's Auditors") and the Seller's representatives such
reasonable access during normal business hours to the books and records of the
business of the Purchaser as the Seller and the Seller's Auditors shall
reasonably request in order to enable the Seller to exercise its rights under
this Section 3.2 or (II) in the event that such acquiror does not so agree in
writing with the Seller to maintain the ability to track the financial
performance of the business of the Purchaser to allow it to make the
calculations that are required pursuant to this Section 3.2, then on the
Post-Closing Payment Date such acquiror shall pay to the Seller an amount equal
to $25,000,000 in immediately available funds by wire transfer to such account
as the Seller shall designate in writing to the Purchaser.

         3.3      Allocation.

                  (a)      Within one hundred twenty (120) Business Days after
the Closing Date, the Purchaser shall prepare and deliver to the Seller a
schedule (a "Proposed Allocation Schedule") allocating the sum of the Purchase
Price and the Assumed Liabilities among the Purchased Assets and the
non-competition covenant provided for in Section 7.7, in such amounts reasonably
determined by the Purchaser to be consistent with Section 1060 of the Code and
the Treasury Regulations thereunder.

                  (b)      The Seller shall have a period of twenty (20)
Business Days after the delivery of the Proposed Allocation Schedule (the
"Response Period") to present in writing to the Purchaser notice of any
objections the Seller may have to the allocations set forth therein (an
"Allocation Objection Notice"). Unless the Seller timely objects, such Proposed
Allocation Schedule shall be binding on the parties without further adjustment,
absent manifest error (the "Binding Allocation Schedule"). In the event that the
Purchaser does not deliver to the Seller the Proposed Allocation Schedule within
the time period specified in Section 3.3(a), the Seller shall be free to
allocate the Purchase Price and the Assumed Liabilities in such manner as the
Seller shall determine in its sole discretion.





                                                                              32

                  (c)      If the Seller shall raise any objections within the
Response Period, the Purchaser and the Seller shall negotiate in good faith and
use their commercially reasonable efforts to resolve such dispute as soon as
practicable after the delivery of the Allocation Objection Notice in a manner
consistent with Section 1060 of the Code and the Treasury Regulations thereunder
(such resolution, the "Agreed Allocation Schedule"); provided, however, that if
the Purchaser and the Seller shall not have reached an agreement regarding the
Proposed Allocation Schedule by the twentieth (20th) Business Day following the
delivery of such Allocation Objection Notice, the parties shall be free to make
their respective allocations as each determines in its sole discretion.

                  (d)      Any subsequent adjustments to the sum of the Purchase
Price and Assumed Liabilities shall be reflected in the Proposed Allocation
Schedule, the Binding Allocation Schedule, or the Agreed Allocation Schedule, as
the case may be, in a manner consistent with Section 1060 of the Code and the
Treasury Regulations thereunder.

                  (e)      Each of the Seller and the Purchaser agrees to
cooperate with the other in preparing IRS Form 8594, and to furnish the other
with a copy of such form prepared in draft form within a reasonable period
before its filing due date.

                  (f)      Subject to the provisions of Sections 3.3(b), (c),
(d) and (e), the Purchaser and the Seller each agree to (i) file any Tax Return
required to be filed pursuant to Section 1060 of the Code or the Treasury
Regulations thereunder, (ii) be bound by a Binding Allocation Schedule or an
Agreed Allocation Schedule, (iii) act in a manner consistent with a Binding
Allocation Schedule or an Agreed Allocation Schedule in the preparation of
financial statements and filing of all federal, state and local income Tax
Returns (including filing Form 8594 with their respective federal income Tax
Returns for the taxable year that includes the Closing Date) and in the course
of any Tax audit, Tax review or Tax litigation relating thereto, and (iv) take
no position and cause their Affiliates to take no position inconsistent with a
Binding Allocation Schedule or an Agreed Allocation Schedule for any Tax
purposes unless required by Law or determination of a Governmental Body.

                  (g)      The Purchaser's employer identification number is
56-0732648. The Seller's employer identification number is 13-1600079.

                               SECTION 4. CLOSING

         4.1      Closing. The closing of the transactions contemplated by this

                                                                              46

           SECTION 6. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

         The Purchaser represents and warrants to the Seller as of the date
hereof as follows:

         6.1      Corporate Organization. The Purchaser is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. It has all requisite corporate power to own, lease and operate its
properties, to carry on its business as now being conducted, to assume the
Assumed Liabilities and to accept the Bill of Sale, Assignment and Assumption
Agreement. The Purchaser is duly qualified or licensed to do business as a
foreign corporation and is in good standing in every jurisdiction where the
ownership, leasing or operation of its properties or the conduct of its business
require such qualification or licensing, other than jurisdictions where failure
to be so qualified or licensed would not have a material adverse effect on the
Purchaser's ability to consummate the transactions contemplated by the
Transaction Documents.

         6.2      Corporate Authority. The Purchaser has all requisite corporate
power and authority (a) to enter into, execute and deliver the Transaction
Documents to which it is or shall be a party, (b) to consummate the transactions
contemplated by the Transaction Documents to which it is or shall be a party,
and (c) to perform fully its obligations under the Transaction Documents to
which it is or shall be a party. All corporate acts and other proceedings
required to be taken by or on the part of the Purchaser and its stockholders to
authorize, execute, deliver and perform the Transaction Documents to which it is
or shall be a party and the transactions contemplated thereby have been duly and
properly taken, and no other corporate action by the Purchaser or its
stockholders is required for the due execution, delivery or performance of this
Agreement or the other Transaction Documents to which it is or shall be a party.
This Agreement has been duly authorized, executed and delivered by the Purchaser
and constitutes, and each of the other Transaction Documents to which it is or
shall be a party has been duly authorized by the Purchaser and when duly
executed and delivered by the Purchaser will constitute, valid and binding
obligations of the Purchaser, enforceable against the Purchaser in accordance
with their respective terms, assuming due execution and delivery hereof and
thereof by the Seller, and except as limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar Laws, now or hereafter
in effect, relating to, or affecting the rights of creditors or creditors'
rights generally or by general principles of equity (regardless of whether such
enforcement is considered in a proceeding at law or in equity).

         6.3      No Violation. Except for the Consents to be obtained under
Section 5.3 and making all filings and notifications set forth in Schedule 6.4,
the execution and delivery by the Purchaser of the Transaction Documents and the
consummation of the transactions contemplated thereby will not (a) violate the
certificate of incorporation or bylaws of the Purchaser, (b) violate any Law
applicable to the Purchaser, (c) violate or result in the revocation or
suspension of any Permit, or (d) violate, conflict with or result in any breach
of any provision of, or constitute, whether after the giving of notice or lapse
of time or both, a default under any Contract to which the Purchaser is a party,
excluding, in the case of the foregoing clauses (b), (c) and (d), violations,
breaches and defaults which, either individually or in the aggregate, would not
have a material adverse effect on the Purchaser's ability to consummate the
transactions contemplated by the Transaction Documents to which it is or shall
be a party.





                                                                              47

         6.4      Governmental Approvals. No Consent of any Governmental Body is
required in connection with the execution and delivery by the Purchaser of the
Transaction Documents or its consummation of the transactions contemplated
thereby or its performance of any of the provisions thereof on or after the
Closing Date, except (a) filing by the Purchaser with the DOJ and the FTC
pursuant to the HSR Act, and the expiration or termination of all waiting
periods associated therewith, (b) where failure to obtain such Consent would not
have a material adverse effect on the Purchaser's ability to consummate the
transactions contemplated by the Transaction Documents to which it is or shall
be a party, (c) as may be necessary as a result of any facts or circumstances
relating solely to the Seller or its Affiliates, or (d) those set forth in
Schedule 6.4.

         6.5      Financing. As of the date hereof, the Purchaser has obtained
any approvals required from the lenders under the Credit Agreement to effect the
purchase of the Purchased Assets, on the terms and subject to the conditions
contained in the Credit Agreement. The Purchaser is not in default under the
Credit Agreement, nor, to the Knowledge of the Purchaser, does any condition
exist that, with notice or lapse of time or both, would constitute a default by
the Purchaser thereunder or would impair the Purchaser's ability to borrow under
the Credit Agreement.

         6.6      Absence of Litigation. No Litigation is pending or, to the
Knowledge of the Purchaser, threatened which seeks to delay or prevent the
consummation of the transactions contemplated hereby or which is reasonably
likely to materially and adversely affect or restrict the Purchaser's ability to
consummate the transactions contemplated in this Agreement.

                          SECTION 7. FURTHER COVENANTS

         7.1      Access to Information and Documents; Post-Closing Cooperation.

to the approval of the Seller, and to discuss such information with such
representatives; provided, however, that (i) such investigation shall not
unreasonably interfere with any of the businesses or operations of the Seller or
its Affiliates, and (ii) each such officer, employee, representative, financing
source, accountant or other designee of the Purchaser shall be subject to a duty
to maintain the confidentiality of any information so





                                                                              48

received in accordance with the terms of the Mutual Confidential Non-Disclosure
Agreement between the Purchaser and the Seller, dated as of July 17, 2002, as
amended by the Amendment to Mutual Confidential Disclosure Agreement, dated as

Disclosure Agreement - Site Visits, dated February 4, 2004, and the Letter
Agreement Addendum to the Mutual Confidential Disclosure Agreement -

(collectively, the "MCDA"). No investigation by the Purchaser shall diminish or
obviate any of the representations, warranties, covenants or agreements of the
Seller contained in this Agreement.

                  (b)      From and after the Closing Date, the Seller shall
provide the officers, employees, representatives and accountants of the
Purchaser and the Purchaser shall provide the officers, employees,
representatives and accountants of the Seller, reasonable access, during

may reasonably request. The Purchaser shall cause to be preserved and kept all
records relating to the Purchased Assets that are included in the assets
transferred to the Purchaser for such period from and after the Closing as may
be required by or needed for compliance with applicable Law. The Seller shall
cause to be preserved and kept all records retained by it relating to the
Purchased Assets for such period from and after the Closing as may be required
by or needed for compliance with applicable Law.

         7.2      Transition.

                  (a)      Transition Services. Each of the Seller and the
Purchaser shall, and Purchaser shall cause any applicable Purchaser Subsidiary
designated by the Purchaser and party to a Bill of Sale to, use commercially
reasonable efforts to complete the Key Transition Items and all other functions
and services described in the Transition Plan, and to complete the Key
Transition Items and all other functions and services described in the
Transition Plan without any unscheduled disruption or degradation of the quality
or continuity of the Packaged Gas Business or the Excluded Businesses (each such
task description in the Transition Plan, a "Transition Service" and
collectively, the "Transition Services"). The Seller shall provide access to the
Purchaser and the Purchaser's officers, employees, representatives and other
designees (which, in the case of National Welders Supply Company, Inc., shall
act through the Purchaser) in accordance with, and subject to, the provisions of
Section 7.1(a). Without limiting the generality of the foregoing, the Seller and
the Purchaser shall use the highest degree of cooperation in completing the
Transition Plan and shall initiate immediate communication for facilitating the
fastest interactive deliveries. Prior to the Closing, the parties shall
cooperate in good faith to address unanticipated situations relating to the
completion of the Transition Plan (for example, delays caused by Third Parties),
including by amending the Transition Plan in accordance with Section 7.2(b).
Each of the Seller and the Purchaser shall use commercially reasonable efforts
to (i) cause their respective agents, suppliers and service providers to
cooperate in good faith with the other party to enable the orderly transition,
and (ii) successfully implement each Transition Service by the start date set
forth in the Transition Plan (where applicable) and complete each Transition
Service on or before the deadline for such Transition Service set forth in the
Transition Plan (including both Key Transition Items and all other Transition
Services), or as




                                       49

otherwise agreed upon by the parties. If any services, functions or
responsibilities not specifically described in the Transition Plan are
identified as being required to allow Purchaser to assume full operational
control of the Packaged Gas Business and the Purchased Assets at the Closing,
the parties shall modify or update the Transition Plan in accordance with the
provisions of Section 7.2(b). Except as set forth in Section 7.32, and as
otherwise agreed by the parties, each of the parties hereto shall bear its own
costs and expenses incurred in connection with this Section 7.2.

                  (b)      Transition Plan. The Transition Plan identifies (i)
the Transition Services to be performed by the Seller and Purchaser, (ii) the
start date (where applicable) for implementation of a Transition Service by the
Seller and Purchaser, and (iii) the completion date by which each such
Transition Service is to be completed. The Transition Plan shall be modified and
updated by written agreement of the parties during the Transition Period and
neither party shall unreasonably withhold its consent to such modification or
updating. Each party shall promptly notify the other party of any delay or
anticipated delay in meeting any deadline set forth in the Transition Plan as
such notifying party becomes aware of any such delay or anticipated delay.

                  (c)      Transition Managers, Dedication of Resources. As part
of the Seller's obligations under this Agreement, the Seller shall designate an
individual for each category of Transition Services as set forth in the
Transition Plan. Such individuals shall be responsible for managing and
implementing the Transition Services. The Purchaser shall designate an
individual for each category of Transition Service to interface with the Sellers
designees described in the two preceding sentences. Each of the Seller and the
Purchaser acknowledges that the Transition Services are necessary to permit a
smooth transition of the Packaged Gas Business to the Purchaser and to preserve
the goodwill associated with the Packaged Gas Business and the Excluded
Businesses. Each of the Seller and the Purchaser shall dedicate the resources it
deems necessary to assure the accomplishment of its obligations under the
Transition Plan.

                  (d)      Stable Environment. Except as set forth on Schedule
7.2(d), Until the Closing Date, the Seller shall not make any material changes
to the information technology infrastructure that would adversely impact the
Purchaser or the transition of the Packaged Gas Business (including the
Purchaser's ability to extract, download or convert data), without the
Purchaser's prior written consent.

                  (e)      Delays/Difficulties. Each party shall promptly notify
the other party in writing of any delays or difficulties in implementing the
Transition Services as each party becomes aware of such delays or difficulties.

                  (f)      Post-Closing Services. If and to the extent that the
Transition Plan is not complete prior to the Closing for any reason, (i) the
Purchaser shall deliver to the Seller, as early as practicable following the
Closing, a list setting forth those items under the Transition Plan that have
not been completed and (ii) the Seller shall, at the Purchaser's request and at
Seller's own expense, use its commercially reasonable efforts to complete the
Transition Plan as soon as practicable following the Closing, but in no event
later than sixty (60) days after the Closing Date.





                                                                              50

         7.3      Definitionally Purchased and Excluded Assets. If at any time
after the Closing the parties determine that certain assets (including the
Excluded Assets) were definitionally excluded from or included within (as the
case may be) the Purchased Assets to be transferred hereunder or the Joint Use
Property to be jointly used in accordance with Section 7.25, but such assets
were nonetheless intended to be included in, or made available to the Purchaser
or its Affiliates in their operation of, the Purchased Assets, or excluded from
the Purchased Assets and retained by the Seller and its Affiliates in their
operation of the Excluded Assets, or intended to be included as Joint Use
Property, and such assets are necessary to the operation of the Purchased Assets
by the Purchaser or its Affiliates or the operations of the Seller or its
Affiliates with respect to the Excluded Assets, as the case may be, the Seller
and the Purchaser shall cooperate in good faith to determine a mutually
acceptable method for providing the Purchaser or the Seller, and their
respective Affiliates, as the case may be, with timely access to such assets,
taking into account the continued need by the Seller or the Purchaser or their
respective Affiliates for the use of such assets, including by making such
assets Joint Use Property and subject to the provisions of Section 7.25.

         7.4      Assistance Relating to Warranty Rights. Each of the parties
shall use its commercially reasonable efforts to cooperate with the other party
as such other party may reasonably request in connection with any claim that
such other party may desire to make against a Third Party under any warranty or
other right relating to any of the Purchased Assets.

         7.5      Exercise of Rights of First Refusal. In the event that the
Seller has the right to exercise any right of first refusal relating to the
Packaged Gas Business that is not included in the Purchased Assets, and the
Seller has determined that it does not wish to exercise such right, the Seller
shall consult with the Purchaser. If the Purchaser shall so request, the Seller
shall use its commercially reasonable efforts to cooperate with the Purchaser to
exercise such right for the benefit of the Purchaser.

         7.6      Confidentiality Agreements.

                  (a)      Unless and until the Purchaser shall have purchased
the Purchased Assets, for a period of five (5) years from the date hereof, the
Purchaser shall not use for its own purposes or advantages (other than in
connection with the Purchaser's due diligence review and in preparation for the
orderly transition of operational control of the Purchased Assets to the
Purchaser) or publish or disclose to any Third Party (other than legal and
financial consultants of the Purchaser who are subject to a duty to maintain the
confidentiality of the Information) any confidential or proprietary information,
know-how, technology information, analysis, compilations, studies, formulae,

is or becomes a matter of public knowledge through no breach by the Purchaser,
(ii) is lawfully acquired from a Third

Agreement, the Purchaser shall not keep or take, and shall promptly return or
destroy, any and all Information, and shall not keep or take, and shall promptly

foregoing sentence, the Purchaser shall promptly provide the Seller with a
certificate, signed by an appropriate officer of the Purchaser, certifying the
destruction of such Information.

                  (b)      Regardless of whether the Purchaser shall purchase
the Purchased Assets, for a period of five (5) years from the date hereof, the
Purchaser shall not use for its own purposes or advantages or publish or
disclose to any Third Party (other than its legal and financial consultants who
are subject to a duty to maintain the confidentiality of the Information) any
Information to the extent relating to any part of the business of the Seller
other than the Packaged Gas Business and obtained in connection with the
negotiation and consummation of the transactions contemplated by this Agreement,
unless and until such Information (i) is or becomes a matter of public knowledge
through no breach by the Purchaser, (ii) is lawfully acquired from a Third Party
without restrictions of confidentiality, or was already known to the Purchaser

Seller in resisting the disclosure of such Information via a protective Order or
other appropriate legal action, and shall not make disclosure pursuant thereto
until the Seller has had a reasonable opportunity to resist such disclosure,

enforce the terms of this Agreement; provided, that, in case of any potential
disclosure under this subclause (iii), the Seller shall provide the Purchaser
with prompt notice of such request or Order, including copies of subpoenas or
Orders requesting or ordering such Information, cooperate reasonably with the
Purchaser in resisting the disclosure of such Information via a protective Order
or other appropriate legal action, and shall not make disclosure pursuant
thereto until the Purchaser has had a reasonable opportunity to resist such
disclosure, unless the Seller is required to make such disclosure by Law.

                  (d)      For a period of five (5) years from the date hereof,
the Seller shall not, and shall cause its Affiliates and their respective
employees not to, use for its or their own purposes or advantages (other than in
preparation for the orderly transition of operational control of the Purchased
Assets to the Purchaser) or publish or disclose to any Third Party (other than
legal and financial consultants of the Seller who are subject to a duty to
maintain the confidentiality of the Information) any confidential or proprietary
information, know-how, technology information, analysis, compilations, studies,
formulae, trade secret or other documents prepared by or obtained from the
Purchaser (including legal and other professional advisors, accountants,
consultants and financial advisors) in connection with the negotiation and
consummation of the transactions contemplated by this Agreement, including
business and financial information, no matter how obtained (orally, in writing
or observed), or any analysis, compilations, studies and other records and
documents prepared by the Seller (including legal and other professional
advisors, accountants, consultants and financial advisors) which contain or
otherwise reflect such information (collectively, "Purchaser Information"),
unless and until such Purchaser Information (i) is or becomes a matter of public
knowledge through no breach by the Seller, its Affiliates or their respective
employees (ii) is lawfully acquired from a Third Party without restrictions of
confidentiality, or (iii) the Seller is required to disclose such Purchaser
Information by Law or is required to disclose such Purchaser Information in
order to enforce the terms of this Agreement; provided, that, in case of any
potential disclosure under this subclause (iii), the Seller shall provide the
Purchaser with prompt notice of any request or Order, including copies of
subpoenas or Orders requesting or requiring such Purchaser Information,
cooperate reasonably with the Purchaser in resisting the disclosure of such
Information via a protective Order or other appropriate legal action, and shall
not make disclosure pursuant thereto until the Purchaser has had a reasonable
opportunity to resist such disclosure, unless the Seller is required to make
such disclosure by Law. If the Purchaser (x) does not purchase the Purchased
Assets, as contemplated by this Agreement, or (y) following the Closing Date and
the expiration of the Transition Period, the Seller shall not keep or take, and
shall promptly return or destroy, any and all Purchaser Information, and shall
not keep or take, and shall promptly return or destroy, any document or other
thing embodying any such Purchaser Information. With respect to any Purchaser
Information that the Seller destroys pursuant to the foregoing sentence, the
Seller shall promptly provide the Purchaser with a certificate, signed by an
appropriate officer of the Seller, certifying the destruction of such Purchaser
Information.

                  (e)      The provisions of this Section 7.6 shall be in
addition to, and not in substitution of, the provisions of the MCDA.





                                                                              53

         7.7      Non-Competition.

                  (a)      Covenant not to Compete. In order that the Purchaser
may have and enjoy the full benefit of the Packaged Gas Business and the
Purchased Assets and as an inducement to the Purchaser to enter into this
Agreement (without which inducement the Purchaser would not have entered into
this Agreement), the Seller hereby agrees that, except as otherwise provided or
contemplated in any of the Transaction Documents, the Seller shall not, and the
Seller shall cause its Affiliates not to, directly or indirectly, engage or
otherwise participate in the Packaged Gas Business in the United States for a
period of five (5) years from the Closing Date (such five-year period, the
"Non-Competition Period"). Notwithstanding the foregoing, the Seller and its
Affiliates shall have the right at any time to (i) engage in any of the Excluded
Businesses, (ii) engage in the Packaged Gas Business outside of the United
States, (iii) acquire, directly or indirectly, securities listed on any national
securities exchange or traded actively in the national over-the-counter market
of any Person that provides the Competing Business in the United States,
provided the Seller, together with its Affiliates and any member of a group in
which the Seller or its Affiliates are a party, do not own more than ten (10%)
percent of the outstanding voting power of such Person (other than with respect
to the Persons set forth on Schedule 7.7(a) for which there shall be no
limitation on the ownership of outstanding voting power; provided, however, that
from and after such time as any such Person becomes an Affiliate of Seller,
Seller Parent or any of their Affiliates, it or they shall be subject to the
terms of this Section 7.7); (iv) subject to Section 7.7(b), acquire (by
acquisition, merger, consolidation, joint venture or otherwise) a company or
business whose operations include a Competing Business, (v) make sales calls or
joint sales calls with a Third Party Distributor (defined below) in relation to
the sale of products of the Excluded Businesses; provided, however, that the
Seller shall not, and shall cause its Affiliates not to, (A) make any sales
calls or any joint sales calls with any Third Party Distributor involving the
supply of packaged gases or (B) make any sales calls or any joint sales calls
with any Third Party Distributor to any customers of the Packaged Gas Business
as of the date hereof or as of the Closing Date, except for joint sales calls
where a Third Party Distributor currently supplies bulk to any such customer and
the making of joint sales calls was the past practice with respect to such
customer prior to the date hereof (past practice to be determined on an
account-by-account basis), (vi) advise any customer, other than a customer of
the Packaged Gas Business as of the date hereof or as of the Closing Date (each
a "Non-PGB Customer"), of the identity of such Persons' Third Party
Distributors, and provide the details thereof, and make recommendations and
referrals to Non-PGB Customers or potential Non-PGB Customers seeking packaged
gas products of any of such Persons' Third Party Distributors; provided, that
the Seller or any such Affiliate shall treat the Purchaser on equal terms with
such Persons' Third Party Distributors when providing such recommendations or
referrals, (vii) publicize generally in literature, on such Persons' website, or
via other media the identity of such Persons' Third Party Distributors, and
provide the details thereof, and (viii) offer non-account-specific services to
such Persons' Third Party Distributors based on such Persons' global experience
in packaged gases, provided, that, as a condition to providing such services
which relate to the Packaged Gas Business to any such Third Party Distributors,
the Seller shall, or shall cause its Affiliates to, offer such services which
relate to the Packaged Gas Business to the Purchaser on such terms as shall be
mutually agreeable to the Seller and the Purchaser for a term of fifteen (15)
years, unless the applicable Enabling Agreement shall have been terminated and
the Seller shall no longer be providing the Purchaser with the products covered
by such Enabling Agreement. The Purchaser





                                                                              54

hereby acknowledges that none of the Seller or any of its Affiliates has any
right or obligation to prevent any Third Party Distributor from offering on its
own behalf and for its own account packaged gases and related products and
services to any Person. For purposes of this Section 7.7(a), "Third Party
Distributor" shall mean any Third Party which purchases bulk gas from any of the
Seller or its Affiliates for re-packaging and/or resale. For purposes of
clarification, the Seller will not produce or sell dry ice to any customers of
the Packaged Gas Business as of the date hereof, but shall retain the right to
sell dry ice to any other Person.

                  (b)      Acquisitions by any of the Seller and/or its
Affiliates. Notwithstanding anything to the contrary contained in Section
7.7(a), during the Non-Competition Period, the Seller and/or its Affiliates may
acquire any Person who is, directly or indirectly, engaged in a Competing
Business (such Person acquired, being referred to as an "Acquired Competitor")
by means of (i) any merger, consolidation, joint venture or other business
combination pursuant to which the business of an Acquired Competitor is combined
with the business of the Seller and/or its Affiliates, (ii) the acquisition by
any of the Seller and/or its Affiliates, directly or indirectly, of the capital
stock of an Acquired Competitor, by way of tender or exchange offer, negotiated
purchase or other means or (iii) the acquisition by any of the Seller and/or its
Affiliates, directly or indirectly, of the assets, properties or business of an
Acquired Competitor, by way of a direct or indirect purchase, exchange, joint
venture or other means; provided that (A) prior to the date of such acquisition,
such Acquired Competitor shall have already been engaged in a Competing Business
and (B) on the date that the definitive agreements for such acquisition are
executed, the revenues of such Acquired Competitor's Competing Business shall
not exceed fifty percent (50%) of such Acquired Competitor's total revenues for
the preceding twelve (12) month period, other than with respect to the Persons
set forth on Schedule 7.7(b)(i), for which this proviso shall not apply; and
provided, further that, immediately upon the consummation of such acquisition,
(I) if the annual revenues of such Acquired Competitor relating to and arising
from the Competing Business are less than $100,000,000, the Seller shall cause,
and, if applicable, the Seller shall cause its Affiliates to cause, the
divestiture of such Competing Business as promptly as practicable and in any
event not later than eighteen (18) months thereafter, and the Purchaser shall
have a right of first negotiation with respect to such Competing Business
pursuant to Section 7.7(d) or (II) if the annual revenues of the Acquired
Competitor relating to or arising from the Competing Business are greater than
or equal to $100,000,000, the Seller and/or its Affiliates shall not be required
to divest the Competing Business; provided, that such Acquired Competitor shall
have agreed to be bound by Sections 7.6 and 7.8 of this Agreement as an
Affiliate of the Seller. Notwithstanding anything to the contrary contained in
this Section 7.7(b), the Persons listed on Schedule 7.7(b)(i) shall be deemed to
be Acquired Competitors and upon the acquisition of any such Acquired Competitor
during the Non-Competition Period by any of the Seller and/or its Affiliates,
such acquiring party shall be required to divest the Competing Business of such
Acquired Competitor and the Purchaser shall have a right of first negotiation
with respect to such Competing Business pursuant to Section 7.7(d).
Notwithstanding anything to the contrary in this Agreement, Seller or any of its
Affiliates, on the one hand, and any person listed on Schedule 7.7(b)(ii) on the
other, may (i) enter into any merger, consolidation, joint venture or other
business combination, (ii) make any tender or exchange offer or stock purchase
or (iii) acquire assets, properties or business by way of a direct purchase,
exchange, joint venture or other means, without any obligation pursuant to this
Section 7.7 (including any obligation to divest any Competing Business).





                                                                              55

                  (c)      Certain Acquisitions. Notwithstanding anything to the
contrary contained in Section 7.7(a), in the event that a Change of Control
Transaction with an Acquiring Competitor occurs with the Seller Parent within
the Non-Competition Period, then the provisions of Section 7.7(a) shall
terminate and be of no further force or effect immediately upon the
effectiveness of such Change of Control Transaction; provided, however, that in
the event of a Change of Control Transaction with respect to the Seller Parent
pursuant to which the Acquiring Competitor would not otherwise be bound by the
terms of this Agreement, Section 7.7(a) shall not terminate unless such
Acquiring Competitor shall have agreed with the Purchaser that such Acquiring
Competitor, the Seller and, in each case, any successor entity thereof continues
to be bound by Sections 7.6 and 7.8 of this Agreement.

                  (d)      Right of First Negotiation. In the event that, at any
time during the Non-Competition Period, any of the Seller and/or its Affiliates
(i) is required to divest the assets of any Competing Business pursuant to
Section 7.7(b), or (ii) chooses to divest all or any portion of any Competing
Business or any interest therein (whether by stock sale or exchange, asset sale
or exchange, merger, consolidation, joint venture or otherwise) other than
pursuant to 7.7(b) (any transaction described in clauses (i) or (ii), a
"Competing Business Sale"), then the Seller shall, prior to it and/or its
Affiliate entering into any formal negotiation or agreement with any Third Party
relating to such Competing Business Sale, give notice (a "Sale Notice") of such
Competing Business Sale to the Purchaser. Upon the giving of such Sale Notice,
the Seller shall thereafter negotiate and, if applicable, cause its Affiliates
to negotiate, in good faith with the Purchaser for the disposition of such
Competing Business to the Purchaser, it being understood that the Seller may at
any time after the giving of the Sale Notice negotiate and/or agree with any
Person with respect to a Competing Business Sale. A Sale Notice shall contain a
full and complete description of the Competing Business to be sold, which shall
include all information provided to any Third Party. To the extent applicable,
the Seller shall cause its Affiliates not to take any actions that would be
inconsistent with the Seller's obligations pursuant to this Section 7.7(d).

                  (e)      Restrictive Covenants. In the event of a breach of
any of the provisions of Sections 7.7(a), 7.7(b), 7.7(c) or 7.7(d) (together,
the "Restrictive Covenants") by any of the Seller and/or its Affiliates, the
Non-Competition Period shall be extended by a period equal to the duration of
such breach.

                  (f)      Blue-Penciling. It is the desire and intent of the
parties that the Restrictive Covenants will be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought. Accordingly, if any Restrictive Covenant shall be
adjudicated to be invalid or unenforceable, such Restrictive Covenant shall be
deemed amended to the extent necessary in order that such provision be valid and
enforceable, such amendment to apply only with respect to the operation of such
Restrictive Covenant in the particular jurisdiction in which such adjudication
is made.

                  (g)      Severability of Restrictive Covenants. The Seller
acknowledges and agrees that the Restrictive Covenants are reasonable and valid
in geographical and temporal scope and in all other respects. If any court of
competent jurisdiction determines that any of the Restrictive Covenants, or any
part thereof, is invalid or unenforceable, the remainder of the





                                                                              56

Restrictive Covenants shall not thereby be affected and shall be given full
effect without regard to the invalid portions.

         7.8      Non-Solicitation by the Seller of the Purchaser's Employees.
The Seller hereby covenants and agrees that, from and after the date hereof
until the second (2nd) anniversary of the Closing Date, neither it nor any of
its Affiliates will, directly or indirectly, solicit for employment any
Transferred Employee; provided, that this Section 7.8 shall not apply (a) if any
such employee has been terminated by the Purchaser or its Affiliates for any
reason or (b) if any such employee contacts the Seller or its Affiliates (i) in
response to a general solicitation for employment in newspapers or other
periodicals or (ii) on his or her own initiative without any encouragement by
the Seller.

         7.9      Consents and Approvals, etc.

                  (a)      Subject to Section 7.9(c), the Seller and the
Purchaser agree to use their commercially reasonable efforts to obtain all
Consents of all Governmental Bodies and other Persons required in connection
with the transactions contemplated hereby, including for the execution, delivery
and performance of this Agreement and transfer of the Packaged Gas Business and
Purchased Assets to be acquired hereunder by the Purchaser and the license to
the Third Party Intellectual Property.

                  (b)      The Seller agrees to use commercially reasonable
efforts to obtain the Consent of any other party or parties to any Acquired
Contract, Real Property Lease, Seller Real Property Lease, Seller Real Property
Sublease or Third Party Intellectual Property to the transfer, assignment or
license thereof to the Purchaser in all cases in which such Consent is required
for assignment or license, as the case may be, and the Purchaser agrees to use
its commercially reasonable efforts to cooperate with the Seller to obtain any
such Consent; provided, that neither the Seller nor the Purchaser, nor any of
their respective Affiliates, shall be required to pay any consideration or to
provide any financial inducements to any party therefor other than any
assignment fee, other administrative fee or other fee, in each case incurred in
connection with the transfer of (i) the leased motor vehicles by the Seller to
the Purchaser (other than any early termination fees triggered by a decision by
the Purchaser to terminate the lease relating to any acquired motor vehicle
prior to the end of the term thereof, which cost shall be borne solely by the
Purchaser) any of which assignment or administrative fees shall be paid one-half
by the Seller and one-half by the Purchaser, and (ii) the Third Party
Intellectual Property, any of which assignment, administrative or other fees
incurred in connection with the assignment of any Third Party Intellectual
Property shall be paid in full by the Seller (except that the Seller shall not
pay for any such fees to the extent attributable to the transfer of Third Party
Intellectual Property beyond the scope of such Third Party Intellectual Property
enjoyed by the Seller with respect to the Packaged Gas Business as of the
Closing Date). To the extent that any of the Acquired Contracts or Real Property
Leases are not assignable without the Consent of another party, the Bill of
Sale, Assignment and Assumption Agreement, the Bills of Sale and the assignment
of Real Property Leases to be delivered at the Closing pursuant to Sections
4.2(c), 4.2(j) and 4.3(c), shall not constitute an assignment or an attempted
assignment of such Acquired Contract or Real Property Lease if such assignment
or attempted assignment would constitute a breach thereof. If, after the Seller
uses its commercially reasonable efforts to obtain any such Consent, such





                                                                              57

Consent is not obtained, the parties agree to cooperate in any reasonable and
lawful arrangements designed to provide to the Purchaser the same or similar
benefits and liabilities under any such Acquired Contract, Real Property Lease,
Seller Real Property Lease, Seller Real Property Sublease or Third Party
Intellectual Property as would have been obtained by the Purchaser if such
Acquired Contract, Real Property Lease, Seller Real Property Lease, Seller Real
Property Sublease or Third Party Intellectual Property had been assigned or
licensed, as the case may be, to the Purchaser effective on the Closing Date,
including the subcontracting thereof to the Purchaser and enforcement for the
benefit of the Purchaser of any and all rights of the Seller against the other
party thereto arising out of the breach or cancellation thereof by such other
party or otherwise. If and to the extent such arrangements cannot be made, the
Purchaser shall have no obligation with respect to any such Acquired Contract,
Real Property Lease, Seller Real Property Lease, Seller Real Property Sublease
or Third Party Intellectual Property. The Seller agrees to use its commercially
reasonable efforts to obtain the Consent of any Governmental Body or other
Person to the transfer or assignment of all Permits to be acquired by the
Purchaser pursuant to Section 2.1(i). To the extent that any Permit (including
any Environmental Permit) is not transferable by the Seller to the Purchaser,
the Seller agrees to use its commercially reasonable efforts to cooperate with
the Purchaser, at the Purchaser's reasonable request, to assist the Purchaser in
its efforts to obtain a substantially equivalent permit.

                  (c)      The Seller and the Purchaser have previously filed
with the FTC and DOJ the respective notification and report forms (the "HSR
Filing") required to be filed by each of them under the HSR Act with respect to
the transactions contemplated hereby. Each party shall promptly inform the other
party of any material communication made by such party to, or received by such
party from, the FTC or DOJ and any requests for additional information from any
Governmental Body with respect to the transactions contemplated by this
Agreement. The parties will use their commercially reasonable efforts to avoid
or eliminate any impediment under any antitrust law that may be asserted by any
United States federal, state or local antitrust authority so as to enable the
parties to close the transactions contemplated hereby expeditiously.
Notwithstanding the foregoing, nothing in this Section 7.9 shall require, or be
construed to require, Purchaser, in connection with the receipt of any
regulatory approval, to proffer or agree to sell or hold separate and agree to
sell or divest before or after the Closing Date, any assets, businesses or
interest in any assets or businesses of Purchaser or of the Packaged Gas
Business (or to the consent to any sale, or agreement to sell, by Purchaser of
any of its assets or businesses or of the Packaged Gas Business) (each a
"Divestiture"), except for one or a series of Divestitures of any assets or
businesses of Purchaser or of the Packaged Gas Business the revenues of which in
the aggregate did not exceed $75,000,000 for the 12 month period ending
September 30, 2003 or (ii) any conditions relating to, or changes or restriction
in, the operations of any such assets or businesses.

                  (d)      Notwithstanding anything in Section 7.9(c) or
otherwise in this Agreement to the contrary:

                           (i)      If the Purchaser is required to effect the
Divestiture of assets or business the revenues derived from which are equal to
or less than $25,000,000 for the 12 month period ending September 30, 2003 in
the aggregate, the Seller shall have no obligation to





                                                                              58

reimburse the Purchaser for any amount and the Purchaser shall be obliged to
effect such Divestiture at its sole cost and expense;

                           (ii)     If the Purchaser is required to effect the
Divestiture of assets or businesses the revenues derived from which exceed
$25,000,000 for the 12 month period ending September 30, 2003 in the aggregate,
the Seller shall reimburse the Purchaser for fifty percent (50%) of any Loss of
Value (defined below) in connection with any such Divestiture in excess of
$25,000,000. "Loss of Value" means the amount, if any, by which (x) the
Benchmark Multiple (defined below) exceeds (y) the value of any proceeds
received by the Purchaser from such Divestiture less the costs and expenses
incurred by the Purchaser in connection with such Divestiture (including,
without limitation, taxes; fees of attorneys, brokers and other professionals or
agents; litigation costs; and any out-of-pocket expenses). "Benchmark Multiple"
means the amount equal to (A) the product of (x) the EBITDA-PGB of the assets
and/or businesses subject to such Divestiture for the twelve (12) month period
prior to such Divestiture and (y) six (6), if such assets and/or businesses are
part of the Packaged Gas Business, or (B) the product of (x) the EBITDA-ARG of
the assets and/or businesses subject to such Divestiture for the twelve (12)
month period prior to such Divestiture and (y) eight (8), if such assets and/or
businesses are owned by the Purchaser or its Affiliates; and

                           (iii)    In the event that the FTC issues a complaint
challenging the transactions contemplated by this Agreement or authorizes its
staff to seek a preliminary injunction to prevent the consummation of the
transactions contemplated by this Agreement notwithstanding an offer by the
parties hereto to enter into a consent Order providing for the Divestiture of
assets or businesses the revenues derived from which equal or exceed $75,000,000
for the 12 month period ending September 30, 2003, this Agreement and the
transactions contemplated hereby may be terminated at the election of the
Purchaser or the Seller pursuant to Section 15.1(e).

                  (e)      The Seller agrees that it shall not, for a period of
sixty (60) days commencing February 2, 2004, file, or participate in the filing
of, or enter into any other transaction that would require the filing of, any
notification and report forms required to be filed under the HSR Act, or enter
into any other transaction which would require FTC or DOJ approval.
Notwithstanding the preceding sentence, the Purchaser may file, or participate
in the filing of, any notification or report forms required to be filed under
the HSR Act at any time in response to the filing of any such notification or
report forms by any Third Party with respect to the Purchaser.

         7.10     Accounts Receivable; Collections and Payments.

                  (a)      From and after the Closing Date, the Seller hereby
constitutes and appoints the Purchaser, its successors and assigns, the true and
lawful attorneys of the Seller with full power of substitution, in the name of
the Seller or otherwise, and on behalf of and for the benefit of the Purchaser,
to demand and receive from time to time any and all Accounts Receivable, to give
receipts, releases or acquittances for or in respect of the same or any part
thereof; to collect, for the account of the Purchaser, all Accounts Receivable
transferred to the Purchaser as provided herein, and to endorse with the name of
the Seller any check received on account of any Accounts Receivable transferred
to the Purchaser; from time to time to institute





                                                                              59

and prosecute in the name of the Seller or otherwise any and all proceedings at
law, in equity or otherwise, which the Purchaser, its successors and assigns,
may deem proper to collect, assert or enforce any claim, right, title, debt or
account hereby assigned or transferred with respect to the Accounts Receivable;
and to take any action necessary to effect the transfer to the Purchaser of full
legal title in and beneficial ownership of any of the Accounts Receivable. The
Seller declares that the foregoing powers are coupled with an interest and shall
not be revocable by it.

                  (b)      The Seller agrees that it shall transfer or deliver
to the Purchaser any cash or other property that the Seller may receive on or
after the Closing Date in respect of any Acquired Contracts, Acquired Permits,
Accounts Receivable or other items related to the Purchased Assets that are
being transferred to the Purchaser as provided in this Agreement within thirty
(30) days after the receipt thereof. The Purchaser agrees upon receipt of any
invoice or demand for payment related to any payables retained by the Seller to
promptly forward such invoice or demand for payment to the Seller.

                  (c)      The Purchaser shall promptly transfer or deliver to
the Seller that portion of all rebates, discounts or similar amounts that the
Purchaser may receive on or after the Closing Date that relate to the operation
of the Packaged Gas Business or the purchase of goods and services, in each
case, by the Seller prior to the Closing Date. The Seller shall promptly
transfer or deliver to the Purchaser that portion of all rebates, discounts or
similar amounts that the Seller may receive on or after the Closing Date that
relate to the purchase of goods and services by the Purchaser on or after the
Closing Date.

         7.11     Conduct of Packaged Gas Business Prior to the Closing Date.
During the period from the date hereof to the Closing Date, except as (A) set
forth on Schedule 7.11, (B) otherwise expressly contemplated by the Transaction
Documents, (C) consented to in writing by the Purchaser (which consent shall not
be unreasonably withheld or delayed), or (D) as required by applicable Law, the
Seller shall conduct the Packaged Gas Business in the Ordinary Course of
Business (including managing its working capital, including inventory at its
stores, in accordance with its past practice and custom) and not in a manner
inconsistent with how the Seller would conduct the Packaged Gas Business if it
was not selling the Packaged Gas Business, and shall use its commercially
reasonable efforts to (i) preserve its business organizations, (ii) keep
available the services of its officers and employees, (iii) preserve the
goodwill of the Packaged Gas Business, (iv) preserve relationships with
customers, suppliers, licensors, distributors, landlords, employees, agents and
other Persons in connection with the Packaged Gas Business, and (v) maintain
sales force activities. Without limiting the generality of the foregoing, during
the period from the date hereof to the Closing Date, the Seller shall not:

                  (a)      sell, lease, license, transfer, pledge, mortgage,
encumber, grant, abandon, allocate to any other business unit, or otherwise
dispose of any Purchased Asset, except dispositions of Purchased Inventory and
Purchased Equipment in the Ordinary Course of Business; provided, however, that
the Seller shall not, in one or a series of transactions, convey or otherwise
transfer title to more than 100 Containers used or held for use in the Packaged
Gas Business to any one Third Party or to any Affiliate of the Seller, in either
case, without the prior written consent of the Purchaser.





                                                                              60

                  (b)      increase the rate of compensation of, or pay or agree
to pay or increase any benefit or incentive to (other than stay bonuses or other
bonus arrangements paid by the Seller, if any), any of the Employees, except in
the Ordinary Course of Business or as required by Law or an existing Contract;

                  (c)      alter the procedures of the Packaged Gas Business
regarding the collection of accounts receivable (for the avoidance of doubt, (i)
the collection practices listed on Schedule 7.11(c)(i) shall be permissible to
the extent such practices are in the Ordinary Course of Business of the Seller
and (ii) the Seller acknowledges and agrees that the collection practices listed
on Schedule 7.11(c)(ii) are not consistent with the Ordinary Course of Business
of the Seller);

                  (d)      take any action, other than in the Ordinary Course of
Business, to modify or change the Valuation Principles;

                  (e)      terminate or materially amend or modify, assign any
material rights relating to, any Real Property Lease or any Acquired Contract,
or enter into any new Contract, other than in the Ordinary Course of Business;

                  (f)      make any capital expenditure or commitment pertaining
to the Packaged Gas Business in excess of (x) $500,000 individually or (y)
$1,000,000 in the aggregate on a monthly basis (or part thereof); and

                  (g)      agree, directly or indirectly, whether in writing or
otherwise, to do any of the foregoing.

         7.12     Exclusivity. As an inducement to the Purchaser to enter into
this Agreement, and in consideration of the time and expense which it has
devoted and will devote to the transactions contemplated hereby during such
period, except as between the Seller and the Purchaser pursuant to this
Agreement, until the earlier of (a) the Closing Date and (b) termination of this
Agreement in accordance with Section 15.1 hereof, the Seller shall not, and the
Seller shall cause its officers, directors, employees, agents and
representatives (including any investment banker, attorney or accountant
retained or acting on behalf of the Seller or any shareholder, director, officer
or employee of the Seller) not to directly or indirectly (i) initiate, solicit,
encourage or entertain proposals, inquiries, indications of interest, or offers
to purchase all or a portion of the Purchased Assets (an "Acquisition
Proposal"), or (ii) enter into any discussions, negotiations, agreements,
arrangements or commitments with respect an Acquisition Proposal with any
Person; provided, however, that the foregoing shall not restrict the Seller from
dispositions in the Ordinary Course of Business of Purchased Inventory and of
Purchased Equipment that is obsolete or in unusable condition and not necessary
for the operation of the Packaged Gas Business as currently conducted by the
Seller. The Seller will immediately cease any existing discussions with any
Persons concerning any Acquisition Proposal and will notify the Purchaser
promptly after it receives any Acquisition Proposal.

         7.13     Agreements. From the date hereof through the Closing Date, the
Seller shall notify the Purchaser of its receipt of any written notice that a
party to any Material Contract has





                                                                              61

terminated or declined to renew or intends to terminate or decline to renew any
such Contract or that any party has asserted or intends to assert any claim
under any such Contract.

         7.14     Excluded Containers. As soon as practicable, but in no event
later than three (3) months following the Closing Date, or immediately upon
written notice from the Purchaser if any Excluded Containers are discovered by
the Purchaser within sixteen (16) months after the Closing Date, the Seller, at
its sole cost and expense, shall remove any Excluded Containers from the
Purchaser's property or otherwise and properly dispose of all such Excluded
Containers.

         7.15     Removal of Excluded Assets. Prior to the Closing, the Seller
shall segregate, remove or, with the written consent of the Purchaser, abandon
any Excluded Equipment (other than Excluded Containers, which are addressed in
Section 7.14) from those assets and operations of the Seller that are to become
Purchased Assets, except to the extent otherwise contemplated by any of the
Enabling Agreements.

         7.16     The Seller's Trademarks.

                  (a)      The Seller and the Purchaser acknowledge that certain
cylinders, dewars, lecture bottles and other containers that are included in the
Purchased Assets are stamped with certain trademarks owned or used by the
Seller, including those described on Schedule 7.16(a) (such trademarks listed on
Schedule 7.16(a), the "Marks" and such cylinders, dewars, lecture bottles and
other containers, the "Imprinted Containers"). In order to obviate the need for
the Purchaser to remark such Imprinted Containers, the Purchaser shall have the
right to use such Imprinted Containers in operating the Packaged Gas Business in
the Ordinary Course of Business on and after the Closing Date and shall not be
required to remove any trademarks or other markings, including the Marks, from
such Imprinted Containers; provided that the Purchaser shall use commercially
reasonable efforts to, as promptly as practicable, remove, strike over, sticker
over or otherwise obliterate the Marks from the Imprinted Containers solely to
the extent the Marks are present on Imprinted Containers as stickers, painted
symbols or via any other impermanent method (for the avoidance of doubt,
impermanent methods do not include stamping or engraving or neck rings attached
to Containers), except that with respect to Imprinted Containers that are stored
for future use, the Purchaser shall place an Airgas label on all Imprinted
Containers filled and shall use commercially reasonable efforts to remove,
strike over, sticker over or otherwise obliterate the Marks from such Imprinted
Containers prior to the use and distribution of such Imprinted Container in
connection with the Packaged Gas Business; provided, further that with respect
to any other materials or things transferred pursuant to this Agreement that
contain any Mark, the Purchaser shall use commercially reasonable efforts to
remove, strike over, sticker over or otherwise obliterate such Marks prior to
such items being distributed by the Purchaser to any Third Party. Purchaser
shall have no obligation to remove, strike over, sticker over or otherwise
obliterate any trademarks or other markings other than the Marks.
Notwithstanding the foregoing, the Purchaser shall not have any right to use the
Marks other than as specifically set forth above and, among other things, the
Purchaser shall not (i) claim any right, title or interest in or to any Mark by
registration or otherwise; (ii) use any Mark in any marketing activity; (iii)
apply any Mark to any product, package or container other than as provided
herein; or (iv) except to the extent that the Marks remain on the Imprinted
Containers in accordance with this Section 7.16(a), use any Mark as a corporate
name or





                                                                              62

trademark in whole or in part. The Purchaser hereby assigns to the Seller any
rights it might acquire in or to each Mark through use or otherwise, including
any goodwill symbolized thereby or associated therewith. Nothing in this Section
7.16(a) shall restrict the ability of the Purchaser to transfer to a Third Party
or otherwise dispose of any Imprinted Container; provided, however, that any
subsequent acquirer of any Imprinted Container shall have only such rights with
respect to the Marks as granted to the Purchaser pursuant to this Section
7.16(a) and shall be subject to all limitations imposed hereunder on the
Purchaser with respect to the use or transfer of the Marks.

                  (b)      By the date that is no later than one hundred eighty
(180) days following the Closing Date, the Seller shall either remove or modify
the Marks from any of the Seller's cylinders, dewars, lecture bottles and/or
other containers that are not part of the Purchased Assets such that the Marks
BOC, BOC Gases or Airco do not appear on such Containers alone but instead
appear only in conjunction with another of Seller's trademarks (e.g., BOC
Edwards).

                  (c)      At least ten (10) days prior to the Closing Date the
Seller shall deliver to the Purchaser a list of all stampings, engravings and
neckrings other than the Marks that are on the Containers that are part of the
Purchased Assets.

         7.17     Access and Cooperation. From and after the Closing Date, the
parties shall take the following measures in order to facilitate the timely and
cost-effective performance of their obligations pursuant to (x) any
environmental transfer Laws ("Transfer Obligations"), (y) any Seller's
Remediation or (z) any investigations described in Section 7.27 hereof, in each
case concerning any particular Real Property that is either Owned Real Property
or Leased Real Property ("Subject Property"):

                  (a)      The Seller, and those Persons acting at the direction
of the Seller, may enter upon and use the Subject Property, at reasonable times
and with reasonable prior notice, including use of roads and driveways, for the
purpose of complying with the Seller's Transfer Obligations and performing
Seller's Remediation.

                  (b)      The Seller shall perform all Remediation at the
Subject Property in compliance with all Laws, including Environmental Laws, and
in such a manner as to minimize, to the extent practicable, damage to the
Subject Property (including to the Improvements, fixtures and appurtenances
thereon) and the disruption of or interference with the Purchaser's use of the
Subject Property (including the Improvements, fixtures and appurtenances
thereon). The Purchaser shall not use the Subject Property in such a manner as
would exacerbate the condition that is subject to the Seller's Remediation.
Without limiting the foregoing, the Purchaser shall not use the lime ponds at
the Miamiville, Ohio, or the Ringgold, Georgia, facilities for any purpose
until, with respect to each such facility, an approval from a Governmental Body
indicating the completion of such Remediation has been obtained.

                  (c)      The Seller shall be responsible for the cost of any
repairs, replacements or damages to the Purchaser's Improvements, fixtures and
appurtenances within the Subject Property to the extent caused by the act or
omission of the Seller or caused by any Seller's Remediation. The Purchaser
shall be responsible for the cost of any repairs, replacements or





                                                                              63

damages to the Seller's Improvements, fixtures and appurtenances within the
Subject Property to the extent caused by the act or omission of the Purchaser.

                  (d)      The Seller may connect to any utility lines which
serve the Subject Property, in order to provide water, electric, telephone,
sanitary sewer, storm sewer and other utility services to the Seller in
connection with the Seller's Remediation; provided, that the Seller shall obtain
all necessary utility approvals and permits prior to making any connections; and
that further, the Seller shall reimburse the Purchaser for all costs which the
Purchaser incurs as a result of the Seller's use of such utilities.

         7.18     Tax Cooperation and Exchange of Information. The Seller and
the Purchaser will provide each other with such cooperation and information as
either of them reasonably may request of the other in filing any Tax Return
(including, for the avoidance of doubt, any amended Tax Returns or claims for
refund), determining any liability for Taxes or a right to a refund of Taxes or
participating in or conducting any audit or other proceeding in respect of Taxes
relating to the Purchased Assets or the Packaged Gas Business. Such cooperation
and information shall include providing copies of relevant Tax Returns or
portions thereof, together with accompanying schedules and related work papers
and documents relating to rulings or other determinations by taxing authorities.
The Seller and the Purchaser will make themselves (and their respective
employees) available, on a mutually convenient basis, to provide explanations of
any documents or information provided under this Section 7.18. Each of the
Seller and the Purchaser will retain all Tax Returns, schedules and work papers
and all material records or other documents in its possession (or in the
possession of its Affiliates) relating to Tax matters relevant to the Purchased
Assets or the Packaged Gas Business for the taxable period first ending after
the Closing and for all prior taxable periods until the expiration of the
statute of limitations of the taxable periods to which such Tax Returns and
other documents relate. After such time, before the Purchaser shall dispose of
any such documents in its possession (or in the possession of its Affiliates),
the Seller shall be given the opportunity, after ninety (90) days' prior written
notice, to remove and retain all or any part of such documents as the Seller may
select. Any information obtained under this Section 7.18 shall be kept
confidential, except as may be otherwise necessary in connection with the filing
of Tax Returns or claims for refund or in conducting an audit or other
proceeding.

         7.19     Litigation. From the date hereof through the Closing Date, the
Seller shall notify promptly the Purchaser of (a) any Actions of the type
described in Section 5.10(a) and (b) any material Actions described in Section
5.10(d) or 5.10(e) that in each case from and after the date hereof are
commenced or, to the Knowledge of the Seller, threatened, against the Seller.
From the date hereof to the Closing Date, each party shall promptly notify the
other party of any Actions commenced or, to the Knowledge of such party,
threatened that, if adversely determined, would impair the ability of such party
to consummate the transactions contemplated hereby.

         7.20     Acquisition Agreements. In the event that, from time to time,
the Purchaser has suffered losses in connection with any matter with respect to
which the Purchaser is not entitled to indemnification by the Seller hereunder,
at the written request of the Purchaser, the Seller shall cooperate with the
Purchaser to enforce for the benefit of the Purchaser, at the Purchaser's
expense, any indemnification rights the Seller may have under any Contract
pursuant to which





                                                                              64

the Seller acquired any of the Purchased Assets, to the extent indemnification
with respect to such matter is available under such Contract, or assign such
rights to the Purchaser to the extent of the applicable claim; provided, that
neither the Seller nor any of its Affiliates shall be required to expend any
funds in connection herewith.

         7.21     Closing Conditions. Subject to Section 7.9(c), the Seller, on
the one hand, and each Purchaser, on the other hand, agree to use their
commercially reasonable efforts to cause all of the conditions to its
obligations and the obligations of the other parties hereto to consummate the
transactions contemplated hereby (other than the conditions contained in
Sections 8.3, 8.13 and 8.14, which conditions are exclusively the subject of
Section 7.2) to be satisfied as soon as practicable after the date of this
Agreement.

         7.22     Instruments of Transfer. On the Closing Date, the Seller shall
deliver to the Purchaser or any Purchaser Subsidiary to which the Purchaser
assigns its rights hereunder, one or more executed Bills of Sale, and such other
good and sufficient instruments of assignment, transfer and conveyance, in form
and substance reasonably satisfactory to the Seller and the Purchaser, and their
respective counsel, as the Purchaser shall reasonably request to vest in the
Purchaser or such the Purchaser Subsidiary all of the Seller's title to the
Purchased Assets. With respect to the Owned Real Property, the Seller shall
convey such Owned Real Property to the Purchaser by recordable special warranty
deed or its equivalent under applicable state Laws. Simultaneously with such
delivery, the Seller shall take all actions necessary to put the Purchaser or
such the Purchaser Subsidiary in actual possession and operating control of the
Purchased Assets. From and after the Closing Date, upon request of the
Purchaser, the Seller shall execute, acknowledge and deliver all such further
assignments, transfers, conveyances and other instruments as the Purchaser shall
reasonably request to assign, transfer and convey to and vest in the Purchaser
its right, title and interest in the Purchased Assets, and as otherwise may be
appropriate to carry out the transactions contemplated by this Agreement. From
and after the Closing Date, upon the request of either the Seller or Purchaser,
the other party shall execute, acknowledge and deliver all such further
assignments, transfers, conveyances, or other instruments or documents, in form
and substance mutually acceptable to the parties hereto, and take such other
actions as may be reasonably required by the requesting party for the effective
assigning, transferring, granting, conveying, sharing, assuring and confirming
to the requesting party of any interests relating to the Owned Real Property,
Shared Sites, Retained Real Property and Excluded Businesses that is designated
to be acquired, assigned, leased or otherwise transferred to such party under
this Agreement.

         7.23     Assumption of Liabilities by the Purchaser. On the Closing
Date, the Purchaser shall deliver to the Seller an executed Bill of Sale,
Assignment and Assumption Agreement and such other good and sufficient
instruments of assumption, transfer and conveyance, in form and substance
reasonably satisfactory to the Seller and the Purchaser, and their respective
counsel, as the Seller shall reasonably request to vest in the Purchaser all of
the Assumed Liabilities. From and after the Closing Date, upon request of the

transactions contemplated by this Agreement.





                                                                              65

         7.24     Title Commitments. At least thirty (30) days prior to Closing,
the Seller shall furnish to the Purchaser, at the Seller's expense, a current
commitment for title insurance issued by the Title Company with respect to each
parcel of Owned Real Property; provided, that, the Purchaser shall bear all
expenses associated with the issuance of any title insurance policies for the
Owned Real Properties.

         7.25     Joint Use Property. The Seller and the Purchaser acknowledge
that, after the Closing Date, those Purchased Assets and those Excluded Assets
set forth on Schedule DEF-6 will be Joint Use Property. From and after the
Closing Date, the Seller and the Purchaser agree to negotiate and cooperate in
good faith in order to reach any reasonable and mutually agreeable arrangements
to provide the other party with the same benefits that the Seller derived from
any Joint Use Property prior to the Closing Date with respect to the Packaged
Gas Business and the Excluded Businesses, including by providing similar
substitute equipment to the other party. Without limiting and in furtherance of
the foregoing, the Seller agrees to provide the Purchaser with such information
necessary or desirable for the parties to determine the historical usage of such
Joint Use Property and each of the Seller and the Purchaser agree to provide the
other party with access to any such Joint Use Property.

         7.26     Shared Sites. Subject to any required Consents, the Seller and
the Purchaser shall enter into a Purchaser Real Property Lease, Purchaser Real
Property Sublease, Seller Real Property Lease or Seller Real Property Sublease,
as the case may be, for the Owned Real Property, Leased Real Property or
Retained Real Property for each of those sites listed on Schedule 7.26. The
Seller and the Purchaser shall execute and deliver, at or after the Closing,
such other agreements, including easement agreements, as shall be necessary to
allow the Seller and the Purchaser to operate their businesses on the Shared
Sites in the Ordinary Course of Business, each such other agreement to be in
form and substance mutually acceptable to the parties hereto.

         7.27     Environmental Assessment Reports.

                  (a)      The Seller and the Purchaser shall cause to be
prepared a Phase I environmental site assessment report (each, a "Phase I
Report"), undertaken in accordance with the standards known as ASTM E 1527-00
Standard Practices for Environmental Site Assessments - Phase I Environmental
Site Assessment Process, certified to both the Seller and the Purchaser, with
respect to each parcel of Real Property, to determine whether any Recognized
Environmental Conditions (as defined in the ASTM Standards) exist there. The
Seller and the Purchaser shall bear the costs and expenses associated with such
Phase I Reports equally. A copy of each Phase I Report shall be delivered to the
Seller and the Purchaser promptly after the date upon which such Phase I Report
is completed (each such date, a "Phase I Completion Date"). Prior to the date
that is five (5) Business Days prior to the Closing Date, the Seller shall
indicate to the Purchaser whether it shall retain its interest in any parcel of
Owned Real Property so as to facilitate Remediation thereof; provided, however,
that in the event that the Seller exercises its right pursuant to this sentence
to retain its interest in the Owned Real Property in question, the parties shall
promptly enter into a Seller Real Property Lease.

                  (b)      Prior to the date that is six (6) Business Days after
each Phase I Completion Date, where any Recognized Environmental Condition is
identified due to the actual




                                       66

or conjectured presence of environmental contamination at an Owned Real Property
in question, or at a Leased Real Property where the Recognized Environmental
Condition is identified as potentially arising out of the Seller's actions, the
Seller shall initiate a Phase II environmental site assessment in respect of
each such Recognized Environmental Condition; provided, however, that upon
request by the Seller, the Purchaser may waive the requirement that the Seller
undertake a Phase II environmental site assessment with respect to any
particular Recognized Environmental Condition. A copy of a report of each Phase
II environmental site assessment and any additional environmental site
assessment necessary to delineate the Recognized Environmental Condition in
question (each site assessment or other such reports, a "Phase II Report") shall
promptly be delivered to the Seller and the Purchaser as it is completed. With
respect to either Owned Real Property or Leased Real Property, where the
Recognized Environmental Condition is identified solely due to Hazardous
Substances migrating onto the property from an off-site source, no Phase II
Report shall be prepared pursuant to this Section 7.27(b).

         7.28     Schedules. From and after the date hereof until the Closing
Date, the parties shall cooperate to correct any information on any Schedules
delivered in connection with this Agreement and to provide further detail with
respect to any Schedule for which generic descriptions were provided. Upon
agreement of the parties, any such supplements and amendments shall supersede
any previous Schedules provided by the Seller to the Purchaser for all purposes
of this Agreement.

         7.29     Financing. The Purchaser will use its best endeavors not to
cause a default under the Credit Agreement prior to the Closing Date.

         7.30     Other Agreements Related to the Excluded Businesses.

                  (a)      If Seller is not self-supplying liquid nitrogen for
its requirement for MRI nitrogen it will seek supplies from Purchaser for dewar
nitrogen.

                  (b)      Seller shall have the right to commercialize any new
technology that is part of its New Technology Business directly on its own
behalf. If Seller chooses to make any such new technology generally available to
Third Party industrial gas distributors Seller shall also make such new
technology available to Purchaser upon terms and conditions mutually agreed
upon, taking into account, among other things, Seller's relationship with
Purchaser.

         7.31     Interim Financial Statements. At or prior to the Closing, the
Seller shall deliver to the Purchaser, at the Seller's expense, the Interim
Financial Statements, prepared in accordance with the Valuation Principles and
accompanied by a report by PricewaterhouseCoopers, addressed to the Purchaser
and the Seller, with the same scope as, and using the same procedures used in
preparing, the Financial Statements.

         7.32     Ticking Fee. If the Closing Date is delayed in accordance with
the provisions of this Agreement as a result of the occurrence of a Transition
Extension Event, then the Purchaser shall pay to the Seller an amount per each
thirty or thirty-one day period (as provided below) of such delay (prorated for
any partial period) as follows:





                                                                              67

                           (i)      $375,000 for the first thirty days of such
delay;

                           (ii)     $1,500,000 for the next thirty-one days of
such delay; and

                           (iii)    $3,000,000 for each thirty or thirty-one day
period (on an alternating basis) of such delay thereafter.

         7.33     Finalization of Certain Enabling Agreements. The Seller and
the Purchaser shall negotiate in good faith to finalize, on mutually agreeable
terms and as soon as practicable after the date of this Agreement, those
Enabling Agreements for which term sheets are attached as Exhibits hereto.

         7.34     Duty to Notify. Each of the Seller and the Purchaser hereby
agree to give prompt written notice to the other party of any event, condition
or set of circumstances occurring or existing on or after the date hereof that,
directly or indirectly, (a) may contravene, conflict with or result in a
violation or breach of (i) any representation or warranty of such party
contained in this Agreement or any certificate delivered pursuant to Sections
8.5 or 9.3 of this Agreement, whether made as of the date hereof, as of the
Closing Date, or any other date or (ii) any covenant or agreement of such party
contained in this Agreement, or (b) may render any of the conditions specified
in Sections 8 or 9 of this Agreement incapable of being satisfied before October
29, 2003; provided, however, that no such notification shall affect the
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement or any of the
other Transaction Documents. Any such notice shall describe the circumstances
giving rise to such notice in reasonable detail and shall reference the section
numbers to this Agreement of the representations, warranties, covenants,
agreements and/or conditions to which it relates.

         7.35     Additional Real Property Matters. At any time after the
Closing, upon written request by the Seller, the Seller and the Purchaser shall
negotiate in good faith to transfer or lease to the Seller such portion of the
real property site to be owned by the Purchaser at Lansing, Michigan, as is
required by the Seller for it to install a liquid helium center at such
location.

                              SECTION 10. EMPLOYEES

employment to the Employees pursuant to the procedures set forth in this Section
10.1.

                  (a)      Aligned Employees. The Purchaser shall, at least
thirty (30) days prior to Closing, make offers of employment to each of the
Aligned Employees, except to the extent individuals are added to the list of

case the Purchaser shall make offers of employment to such Aligned Employees as
many days prior to the Closing as is reasonably practicable.

                  (b)      Unaligned Employees. The Purchaser shall, at least
fourteen (14) days prior to Closing, make offers of employment to the Unaligned

                  (e)      Sales Employees. The Seller and the Purchaser shall

the list of Sales Employees set forth on Schedule DEF-8 persons whom the
Purchaser and the Seller, respectively, shall add to the list of "Aligned

                                                                              72

Agreement. The selection described in the preceding sentence shall be made no
later than ten (10) days prior to the announcement of such selection, which
announcement shall be made no later than April 30, 2004.

                  (f)      Notice.

                           (i)      The Purchaser shall notify the Seller in
writing (by email or telecopy to the Director of Human Resources for the
Seller's U.S. ISP business) as to each Employee who has accepted an offer of
employment and each Employee who has rejected an offer of employment made
pursuant to Section 10.1(a) or (b) (and, in the case of a rejected offer, shall
provide the Seller with a copy of the applicable offer letter), in each instance
within seven (7) Business Days following the receipt of such acceptance or
rejection; provided, however, that such notice shall be provided no later than
five (5) Business Days prior to Closing.

                           (ii)     The Seller shall notify the Purchaser within
seven (7) Business Days after any CSC Employee or Unaligned Employee becomes a
Transferred Employee whether such Transferred Employee has a Seller-leased
vehicle, which lease will have been listed on the updated Schedule 2.1(c)(iii)
at Closing.

                  (g)      Responsibility for Certain Employees; Offers.

                           (i)      Offers. If the Purchaser makes an offer of
employment to any Employee which offer includes (A) a total annual cash
compensation opportunity (base salary (or hourly rate of pay, as applicable)
plus such Employee's current bonus target) that is at least equal to 90% of the
Employee's current total cash compensation opportunity (base salary (or hourly
rate of pay, as applicable) plus such Employee's current bonus target) and (B)
employment at a location that does not extend the Employee's current one-way
commute greater than 50 miles, as measured by the most commonly traveled route,
then such offer of employment will be considered a "Qualifying Offer." Any offer
of employment by the Purchaser to an Employee that does not meet the
requirements for a Qualifying Offer is hereinafter referred to as a
"Non-Qualifying Offer."

                           (ii)     Qualifying Offers. If the Purchaser makes a
Qualifying Offer of employment to an Employee and such Employee does not accept
such Qualifying Offer prior to the Closing Date for any reason, the Purchaser
shall have no obligation to hire the Employee and the Purchaser shall not be
responsible for any costs or liabilities associated with such Employee,
including with respect to the termination of such Employee's employment. The
Seller shall cease to employ any Employee who does not accept a Qualifying Offer
of employment made to such Employee by the Purchaser and shall not rehire any
such Employee for a period of at least twelve (12) months following the Closing
Date without the prior written consent of the Purchaser.

                           (iii)    Non-Qualifying Offers. If the Purchaser
makes a Non-Qualifying Offer of employment to any Employee and such Employee
does not accept such Non-Qualifying Offer for any reason, then (A) the Seller
shall cease to employ such Employee and neither the Purchaser nor the Seller
shall rehire any such Employee for a period of at least twelve (12)





                                                                              73

months following the Closing Date without the prior written consent of the other
party, (B) the Seller shall pay such Employee a cash severance payment in
accordance with the terms of the BOC Group Severance Security Plan (the "Seller
Severance Plan") as in effect on the date hereof (each such payment a "Severance
Payment") (it being agreed by the parties that the formula for calculating the
Severance Payments is set forth on Schedule 10.1(g)(iii)) and (C) the Purchaser
shall, within thirty (30) days of receipt of an invoice from the Seller,
reimburse the Seller for one-half of the total Severance Payments made in
accordance with clause (B) above. If the Purchaser makes a Non-Qualifying Offer
of employment to an Employee and such Employee accepts such Non-Qualifying
Offer, then (x) subject to Section 10.2, the Employee shall become a Transferred
Employee pursuant to Section 10.2, (y) the Purchaser shall pay such Employee an
amount equal to the amount such Employee would have received from the Seller
pursuant to clause (B) of the preceding sentence (excluding pay in lieu of
notice) if the employment of such Employee had been terminated by the Seller
following the rejection of a Non-Qualifying Offer (each such payment, a
"Transition Payment") and (z) the Seller shall, within thirty (30) days of
receipt of an invoice from the Purchaser, reimburse the Purchaser for one-half
of the total Transition Payments made in accordance with clause (y) above.
Notwithstanding anything in this Section 10.1(g) to the contrary, (I) the
Seller's portion of the payments provided in accordance with this Section
10.1(g)(iii) shall not exceed $550,000 in the aggregate (the "Seller Limit") and
the Purchaser shall be responsible for any portion of the Severance Payments
and/or Transition Payments (in each case calculated in accordance with Schedule
10.1(g)(iii)) in excess of the Seller Limit that the Seller would otherwise be
responsible for pursuant to this Section 10.1(g)(iii), and (II) the Seller's
obligation to make any Severance Payments shall be subject to the execution by
the applicable Employee of a release of claims against the Seller and its
Affiliates reasonably satisfactory to the Seller in accordance with the terms of
the Seller's Severance Plan as in effect on the date hereof.

                  (h)      Notwithstanding anything in this Section 10, any
offer of employment made by the Purchaser to any Employee shall comply with
applicable Law.

                  (i)      Employee Information. The Seller agrees to provide,
on the Closing Date, the information listed on Schedule 10.1(i) for each
Transferred Employee (collectively, the "Employee Information"). The Seller
agrees to use commercially reasonable efforts to obtain consents from Employees
who are employed as drivers to include, in addition to the other Employee
Information, such Employee's Department of Transportation records in the
Employee Information provided to the Purchaser.

         10.2     Transferred Employees. Each Employee who accepts an offer of
employment from the Purchaser, whether a Qualifying Offer or a Non-Qualifying
Offer, and who continues to be an employee of the Seller until immediately prior
to the Closing, shall become employed by the Purchaser either (i) as of the
Closing Date, or (ii) in the event any such Employee is on leave approved by the
Seller in the Ordinary Course of Business on the Closing Date, as of the date
that such Employee is no longer on any such approved leave, provided that the
Employee reports to work with the Purchaser within thirty (30) days after the
end of any such approved leave, and in no event, other than a military leave,
later than one-hundred-twenty (120) days following the Closing Date. A list of
Employees on an approved leave, the date such approved leave is expected to end
(if available) and the reason for such approved leave is provided on Schedule





                                                                              74

10.2, such list to be updated as of the Closing. Employees who are employed by
the Purchaser in accordance with the foregoing sentence shall be "Transferred
Employees" from and after their first date of employment with the Purchaser. The
Purchaser shall, subject to any applicable restrictions, have the right to
administer a standard drug test (as administered to all similarly situated
employees hired by the Purchaser in the Ordinary Course of Business) to each
Employee that accepts the Purchaser's offer of employment and the failure of any
such Employee to take or pass such drug test prior to the Closing Date shall be
considered a rejection of a Qualifying Offer of employment. Any Employee who
fails to take or pass such drug test prior to the Closing Date shall not be
deemed a "Transferred Employee" for purposes of this Agreement.

         10.3     Employee Benefits.

                  (a)      The Purchaser shall or shall cause a subsidiary to
extend, on the Closing Date, coverage under the Purchaser's then-existing
employee benefit plans, programs and arrangements, including any "employee
welfare benefit plans" and "employee pension benefit plans," each as defined in
Section 3 of ERISA, to the Transferred Employees on the same terms on which
similarly situated employees of the Purchaser participate in such plans. For all
purposes of such employee benefit plans, programs and arrangements, including,
without limitation, eligibility, participation, vesting and benefit accrual
(other than for benefit accrual for any defined benefit pension plan) the
Purchaser shall credit Transferred Employees for prior service with the Seller
and its Affiliates to the extent the Seller recognized such service; provided,
however, that no Transferred Employee who received a Non-Qualifying Offer will
be credited with service with the Seller or its Affiliates for purposes of any
applicable severance plan of the Purchaser (any such plan, the "Purchaser
Severance Plan").

                  (b)      To the extent permitted by applicable Law, on or as
promptly as practicable after the Closing Date but in no event later than
fifteen (15) days after the applicable Employee becomes a Transferred Employee,
the Seller shall pay to the Purchaser, in respect of all accrued and unused
vacation for each Transferred Employee with respect to the Seller's fiscal year
that includes the Closing Date (the "Current Fiscal Year"), an amount equal to
the product of (i) the number of accrued, but unused, vacation days for such
Transferred Employee, multiplied by (ii) for such Transferred Employee, the
lesser of (A) the daily eight (8) hour rate of base salary (or hourly rate of
pay, as applicable) contained in such Transferred Employee's Offer, and (B) the
daily eight (8) hour rate of base salary (or hourly rate of pay, as applicable)
that the Seller disclosed to the Purchaser pursuant to 5.18(e) as payable to
such Transferred Employee immediately prior to the Closing. The Purchaser shall,
as of the Closing, allow Transferred Employees who have vacation accrued with
respect to the Current Fiscal Year, but unused as of the Closing Date, to use or
be compensated for such vacation following the Closing Date in accordance with
the Purchaser's applicable vacation policies. The Seller shall directly pay to
the Transferred Employees, on or as promptly as practicable after the Closing
Date but in no event later than fifteen (15) days after the applicable Employee
becomes a Transferred Employee, any accrued vacation in respect of any fiscal
year prior to the Current Fiscal Year.

                  (c)      The Purchaser shall (i) cause its group health plans
to cover Transferred Employees employed by the Purchaser and dependents of such
Transferred Employees to the extent such Transferred Employees and dependents
are covered under the Seller's group health





                                                                              75

plans as of the Closing Date and to be responsible (in accordance with the
Purchaser's employee welfare benefit plans and employee pension benefit plans)
for covered expenses incurred by such Transferred Employees and dependents on or
after the Closing Date; (ii) waive proof of insurability requirements for
initial extension of both basic and optional benefit coverage under its group
health plans or other group insurance welfare benefit plans for such Transferred
Employees and dependents; (iii) credit deductible payments and co-insurance
payments made in 2004 by such Transferred Employees and their dependents under
the Seller's group health plans for expenses incurred on or prior to the Closing
Date towards deductibles and out of pocket maximums in effect for its group
health plans for 2004; and (iv) waive all pre-existing condition clauses in its
group health plans for such Transferred Employees and their dependents, but only
to the extent such pre-existing conditions were waived under the Seller's group
health plan. For purposes of the preceding sentence, "group health plan" shall
have the meaning proscribed in Section 5000(b)(1) of the Code. Notwithstanding
the above, in respect of any person who becomes a Transferred Employee after the
Closing Date in accordance with the first sentence of Section 10.2, the term
"Closing Date," as used in this Section 10.3, shall refer to the date on which
such person becomes a Transferred Employee.

                  (d)      Notwithstanding the foregoing, effective as of the
Closing Date, the Transferred Employees shall be eligible to participate in the
Purchaser Severance Plan, a copy of which has been provided to the Seller as of
the date hereof, on the same terms on which similarly situated employees of the
Purchaser participate in such plan; provided, that Purchaser shall credit
Transferred Employees who receive Qualifying Offers for prior service with the
Seller and its Affiliates to the extent the Seller recognized such service for
the purpose of the Seller Severance Plan. If the employment of a Transferred
Employee who received a Non-Qualifying Offer with the Purchaser is terminated by
the Purchaser following the Closing Date, such Transferred Employee shall be
eligible to participate in the Purchaser Severance Plan, but only with respect
to service with the Purchaser.

         10.4     COBRA. The Seller shall be responsible for providing such
continuation coverage, within the meaning of COBRA, as is required pursuant to
COBRA in respect of any Employee or "qualified beneficiary" (as defined in
COBRA) who incurs a "qualifying event" prior to the Closing Date or any Employee
who does not become a Transferred Employee in accordance with Section 10.2. The
Purchaser shall be responsible for providing such continuation coverage as is
required under COBRA in respect of any Transferred Employee employed by the
Purchaser, or qualified beneficiary of a Transferred Employee, in either case,
who incurs a qualifying event on or after the Closing Date.

         10.5     Unemployment Insurance. At the request of the Purchaser, the
Seller, to the extent permitted by relevant state unemployment insurance Law,
agrees to a total or partial transfer of experience rating, and/or transfer of
applicable reserve balances, as applicable, relating to Transferred Employees.
The Seller will provide to the Purchaser information reasonably requested by the
Purchaser to effectuate such transfer.

         10.6     Payroll Tax. For purposes of payroll taxes with respect to all
employees of the Seller that become employees of the Purchaser, the Seller and
the Purchaser agree to treat the





                                                                              76

transactions contemplated herein as a transaction described in Treasury
Regulation Sections 31.3121(a)(1)-1(b)(2) and 31.3306(b)(1)-1(b)(2).

         10.7     Cooperation.

                  (a)      Upon the Purchaser providing reasonable notice to the
Seller, the Seller shall permit the Purchaser a reasonable opportunity to meet
with the Employees during the Seller's and applicable Employee's normal business
hours; provided that the Purchaser shall be responsible for any third-party
out-of-pocket expenses incurred at the Purchaser's request in connection with
any such meeting. Such opportunity shall be in accordance with applicable Laws
and for the sole purpose of informing such Employees about the terms and
conditions of employment with the Purchaser, including information about the
Purchaser's benefit plans. All contact with such Employees initiated by the
Purchaser will be done at the Employee's principal employment location or
another mutually agreed upon location and the Purchaser's representative may, in
the sole discretion of the Seller, be accompanied by at least one Seller
representative during such contact (any costs associated with such Seller
representative to be borne by the Seller). Any meetings held by the Purchaser
with an Employee outside of the Seller's and applicable Employee's normal
business hours shall be conducted solely on a voluntary basis, and the Seller
shall have no liability or obligation with respect thereto.

                  (b)      Notwithstanding Section 10.7(a), the Seller shall
permit the Purchaser to communicate and confer with the Aligned Employees and
Sales Employees set forth on Exhibit D to the Employee Side Letter no later than
the earlier of (x) two (2) weeks following the date hereof and (y) April 15,
2004; provided, however, that (A) any such communications and conferences shall
be subject to the requirements of (i) applicable antitrust Laws and (ii) Section
7.6 of this Agreement and the MCDA, (B) the Purchaser shall be responsible for
any third-party out-of-pocket expenses incurred at the Purchaser's request in
connection with any such communication or conference, (C) any such communication
or conference that occurs or is held outside of the Seller's or applicable
Aligned Employee's or Sales Employee's normal business hours shall be conducted
solely on a voluntary basis, and the Seller shall have no liability or
obligation with respect thereto and (D) any such communication or conference
shall not conflict with the Seller's ability to conduct the Packaged Gas
Business in the Ordinary Course of Business through the Closing Date.

         10.8     WARN. The Purchaser shall be responsible for any obligation
with respect to the Transferred Employees under WARN arising on or after the
Closing Date. The Seller shall be responsible for any such obligation arising
prior to the Closing Date.

         10.9     Collective Bargaining Arrangements. Notwithstanding anything
to the contrary in this Section 10:

                  (a)      The terms and conditions of employment of any
Transferred Employee subject to a collective bargaining agreement that is not an
"Assumed Agreement" (as defined below) shall be in accordance with the
requirements of the National Labor Relations Act, as amended, and any other
applicable Law.





                                                                              77

                  (b)      The Seller shall assign and the Purchaser agrees to
assume as successor employer, as of the Closing Date, the collective bargaining
agreements listed or described in Schedule 10.9(b) covering and only with
respect to Employees in Bellmawr, New Jersey, Hawaii and Ann Arbor, Michigan
(each, an "Assumed Agreement") and continue the employment of the Employees
covered by, and, subject to Section 2.4(p), be responsible for any obligations
arising under, each Assumed Agreement on and after the Closing Date. Each
Employee covered by an Assumed Agreement who is an employee of the Seller
immediately prior to the Closing shall become a Transferred Employee and the
terms and conditions of employment of any such Transferred Employee shall be
subject to the applicable Assumed Agreement (or any successor thereto). Complete
copies of each Assumed Agreement, listed on Schedule 10.9(b), have been provided
to the Seller prior to the date hereof.

                              SECTION 11. BROKERAGE

         The Seller, on the one hand, and the Purchaser, on the other hand,
shall indemnify and hold harmless the other against and in respect of any
liability, cost or expense resulting from any agreement, arrangement or
understanding made by such party with any third party for brokerage or finders
fees or other commissions relative to this Agreement or the transactions
contemplated hereby.

                              SECTION 12. EXPENSES

         Except as otherwise provided herein or therein, each party hereto shall
bear all expenses incurred by it in connection with this Agreement and the other
Transaction Documents and the consummation of the transactions contemplated
hereby and thereby, including all compensation and expenses of their respective
counsels, actuaries, financial advisors and accountants, whether or not the
Closing shall have occurred.

               SECTION 13. TRANSFER TAXES AND RECORDING EXPENSES

         13.1     Transfer and Recording Taxes. The Seller and Purchaser shall
each pay one-half of all sales, use, value added, transfer, stamp, registration,
recording, documentary, excise, real property transfer or gains, or similar
Taxes incurred as a result of the transactions contemplated in this Agreement,
and the Seller and the Purchaser agree to jointly file all required change of
ownership and similar statements; provided, however, that the Purchaser shall be
solely liable for any increase in any of the foregoing Taxes to the extent
attributable to any designation by the Purchaser of any Purchaser Subsidiaries
to purchase any of the Purchased Assets above the amount of the foregoing Taxes
that would have resulted if the Purchaser had effected at the Closing the
purchase of the Purchased Assets and the assumption of the Assumed Liabilities
thereunder. The Seller and the Purchaser agree to cooperate so as to minimize
the amount of any such Taxes. The Purchaser expressly authorizes the Seller to
collect and remit such Taxes as may be required by any applicable Law. If the
purchase of any Purchased Assets is exempt from sales or use Tax, then, where
required by Law, at the Closing, the Purchaser shall deliver to the Seller such
properly completed resale exemption certificates and other similar certificates
or instruments, in form and content acceptable to the Seller, as are necessary
to claim available exemptions from the payment of sales, transfer, use or other
similar Taxes under applicable Law.





                                                                              78

         13.2     Real and Personal Property Taxes. Real and personal property
taxes applicable to any of the Purchased Assets, including but not limited to
any payments made under an Industrial District Agreement or any similar
agreement under which amounts are paid to a Governmental Body in lieu of
property taxes, shall be prorated between the Seller, on the one hand, and the
Purchaser, on the other hand, as of the Closing Date.

         13.3     Tax Returns. The Purchaser and the Seller shall cooperate in
good faith in preparing in a timely manner any and all property transfer Tax
Returns and other similar filings required by Law in connection with the
transactions contemplated hereby and relating to the Purchased Assets, any part
thereof or ownership interest therein, including duly and properly executing and
acknowledging any such filings and executing such affidavits in connection with
such filings as shall have been required by Law or reasonably requested by the
other party. Each party (whether the Purchaser or the Seller, as the case may
be) shall provide copies of such Tax Returns to the other party within a
reasonable period following the filing of such Tax Returns by such party.

            SECTION 14. SURVIVAL OF REPRESENTATIONS; INDEMNIFICATION

         14.1     Survival of Representations and Warranties. The
representations, warranties, covenants and agreements contained in this
Agreement and the other Transaction Documents shall survive the Closing, but
shall be subject to all limitations and other provisions relating thereto
contained in this Agreement. Such representations, warranties, covenants and
agreements contained herein are exclusive, and the parties hereto confirm that
they have not relied upon any other representations, warranties, covenants and
agreements as an inducement to enter into this Agreement or otherwise.

         14.2     Indemnification of the Purchaser. Subject to Sections 14.3 and
14.4 hereof, the Seller agrees to defend, indemnify and hold harmless the
Purchaser and its respective Affiliates and their respective officers,
directors, agents and representatives and the respective successors and
permitted assigns of each of the foregoing (collectively, the "Purchaser
Indemnitees") against and in respect of any costs, damages (including claims for
natural resource damages or Remediation), losses, expenses, claims, obligations,
diminution of value or other liabilities (including legal and other expenses
incurred in investigating and defending or enforcing any claims or deficiencies)
(collectively, "Losses"), incurred by the Purchaser Indemnitees to the extent
resulting or arising from:

                  (a)      a breach of any of the representations or warranties
made by the Seller in Section 5 of this Agreement or in the certificate
delivered pursuant to Section 8.5;

                  (b)      except with respect to Environmental Remediation
Liabilities, which are covered by Section 14.2(c) below, a breach of any of the
covenants or agreements (other than the Transaction Documents and the covenants
or agreements contained in Section 7.2(a) through (g)) made or to be performed
by the Seller pursuant to this Agreement;

                  (c)      all liabilities or obligations to perform Remediation
on or about an Owned Real Property or a Leased Real Property, except to the
extent such liabilities or obligations are





                                                                              79

caused, increased or otherwise exacerbated by the Purchaser or its Affiliates or
agents, arising out of or relating to (collectively, "Environmental Remediation
Liabilities"):

                           (A)      any Known Environmental Liability; or

                           (B)      other than any Known Environmental
         Liabilities, any condition or contamination that Purchaser can show
         arose due to Seller's actions in operating the Packaged Gas Business or
         the Purchased Assets, or the Seller's omissions with respect to the
         operation of the Packaged Gas Business or the Purchased Assets to the
         extent such omissions were inconsistent with obligations under
         applicable Environmental Law or were otherwise not commercially
         reasonable.

                  (d)      except with respect to Environmental Remediation
Liabilities, which are covered by Section 14.2(c) above, the Excluded
Liabilities;

                  (e)      any liability or obligation (excluding Environmental
Remediation Liabilities, which are covered by Section 14.2(c) above) with
respect to the Seller's operation of property subject to a Purchaser Real
Property Lease or the Purchaser Real Property Sublease on or after the Closing
Date; or

                  (f)      any failure to comply with the "bulk sales" laws
applicable to the transactions contemplated by this Agreement.

         The obligations of the Seller hereunder shall bind the successors and
assigns of the Seller.

         For all purposes of Section 14.2, a breach of the Seller's
representations and warranties shall be determined without regard to any
limitation or qualification as to "materiality", "material", "materially" or
"Business Material Adverse Effect" set forth in such representation or warranty.

         14.3     Duration of Indemnification of the Purchaser. The Seller's
obligations to defend, indemnify and hold harmless the Purchaser Indemnitees
under Section 14.2 shall apply only to any Claim Notice (as hereinafter defined)
given pursuant to Section 14.8 within the following periods:

                  Section 14.2(a)   Eighteen (18) months after the Closing Date,
                                    except that the Seller's indemnification

                                    representation or warranty contained in
                                    Sections 5.1, 5.2, the second sentence of
                                    Section 5.9 or the first sentence of Section
                                    5.14(a) shall survive until the expiration
                                    of the applicable statute of limitations.

                  Section 14.2(b)   Eighteen (18) months after the Closing Date
                                    with respect to covenants and agreements of
                                    the Seller that by their terms are to be
                                    performed in full prior to or on the Closing
                                    Date.





                                                                              80

                                    No time limit with respect to covenants and
                                    agreements of the Seller that by their terms
                                    are to be performed or completed after the
                                    Closing Date.

                  Section 14.2(c)   Six (6) years after the Closing Date, except
                                    that Seller's indemnification obligation
                                    with respect to Known Environmental
                                    Liabilities shall have no time limit.

                  Section 14.2(d)   No time limit; provided, that, the Seller's
                                    indemnification obligation with respect to
                                    any claims in respect of Taxes shall survive
                                    until the expiration of the applicable
                                    statute of limitations.

                  Section 14.2(e)   Twelve (12) months after the date on which
                                    Seller ceases to operate the property
                                    subject to a Purchaser Real Property Lease
                                    or the Purchaser Real Property Sublease

                  Section 14.2(f)   No time limit.

         14.4     Limitations on Indemnification of the Purchaser.

                  (a)      The Seller's obligations to defend, indemnify and
hold harmless the Purchaser Indemnitees (i) under Sections 14.2(a) and
14.2(c)(B) shall apply only after the Purchaser Indemnitees have suffered Losses
under Sections 14.2(a) and 14.2(c)(B) (except for those based upon, arising out
of or otherwise in respect of Sections 5.1, 5.2, the second sentence of Section
5.9 or the first sentence of Section 5.14(a)) in excess of an aggregate of four
million dollars ($4,000,000), after which the Seller shall only be obligated to
indemnify Losses in excess of such amount (the "Minimum Amount"), and (ii) in
any case shall apply only after the amount of any individual Loss or any series
of related Losses indemnified against hereunder shall exceed fifty thousand
dollars ($50,000) and then shall apply to the entire amount of such Loss. The
Seller will be obligated only to indemnify Losses relating to Sections 14.2(a)
and 14.2(c)(B) (except for those based upon, arising out of or otherwise in
respect of Section 5.1, 5.2, the second sentence of Section 5.9 or the first
sentence of Section 5.14(a)) up to an aggregate amount equal to twenty-five
percent (25%) the Purchase Price (the "Maximum Amount"). Notwithstanding the
foregoing provisions of this Section 14.4, the Purchaser shall be entitled to
receive indemnification payments in respect of the indemnification payments
under Sections 14.2(b), (c)(A), (d), (e) and (f) without regard to the
individual or aggregate amount thereof, without regard to whether the aggregate
amount of all other indemnification payments shall have exceeded, in the
aggregate, the Minimum Amount or shall have exceeded, in the aggregate, the
Maximum Amount. Any claim which is within the description of Section 14.2(a) or
14.2(b) and which is also within the description of any of Sections 14.2(c)
through 14.2(f), shall be deemed to be asserted and treated hereunder for all
purposes as a claim arising out of Section 14.2(c) through 14.2(f), as
appropriate.

                  (b)      Remediation of Particular Matters. The Seller's
obligation to indemnify the Purchaser Indemnitees pursuant to Section 14.2(c)
shall be subject to and limited by the following conditions:





                                                                              81

                           (i)      Seller's Remediation. The Seller shall have
the right but not the obligation to conduct and control the management of any
Remediation that is subject to indemnification pursuant to this Agreement (any
such Remediation for which the Seller makes such an election, a "Seller's
Remediation"). In furtherance of this right, prior to initiating any Remediation
regarding which the Purchaser may seek indemnification pursuant to Section
14.2(c) hereof, the Purchaser shall notify the Seller of such Environmental
Liability and its intention to undertake such Remediation. The Seller shall,
within thirty (30) days of the Seller's receipt of such notice (or reasonable
shorter period, in the case of an emergency Remediation), indicate to the
Purchaser that (i) it intends to undertake said Remediation or (ii) that more
information is needed from the Purchaser before the Seller can reasonably
determine that the Purchaser's claim would be subject to indemnification
pursuant to this Agreement. The Purchaser shall promptly respond to such
requests for information (to the extent such information is reasonably available
to the Purchaser) and, within thirty (30) days after the Seller's receipt of
such information, the Seller shall notify the Purchaser as to whether it shall
undertake such Remediation. Prior to a determination by the Seller that it shall
undertake such actions pursuant to this Section 14.4(b)(i), the Purchaser shall
take only those actions necessary to comply with applicable Environmental Law or
to address conditions that pose an immediate and acute health risk.
Notwithstanding the procedure set forth in this Section 14.4(b)(i), the parties
hereto agree that all Known Environmental Liabilities are deemed to be Seller's
Remediation.

                           (ii)     Purchaser's Remediation. In undertaking any
Remediation for which the Purchaser shall seek indemnification pursuant to
Section 14.2(c) of this Agreement, the Purchaser shall: (A) utilize only such
actions which (1) are necessary to resolve and discharge the Environmental
Liability in question, and (2) employ the most cost-effective means available
that is consistent with good business practice and the use of the property
immediately prior to the Closing Date and is acceptable to the relevant
Governmental Body; (B) initiate and diligently pursue until completion all such
actions in compliance with all applicable Law, including all Environmental Law;
(C) not cause, through its own action or inaction, any undue delay in obtaining
written notice from the appropriate Governmental Authority that no further
investigation or remediation is necessary with respect to the matter in
question; and (D) provide copies to the Seller of all material correspondence
and reports prior to the Purchaser undertaking any Remediation work at a Subject
Property. In particular, the Purchaser shall provide to the Seller, for the
Seller's review and comment, the Purchaser's proposed Remediation plan, which
shall include the data, evaluations, reports and other information upon which
the Purchaser relied in preparing its proposed Remediation plan. The Seller
shall provide comments to the Purchaser on the proposed Remediation plan within
sixty (60) days (or, in the event that submission of the Remediation plan is
required in less than sixty (60) days under applicable Environmental Law, then
within a reasonable time prior to the submission of the Remediation plan,
provided that the Purchaser shall use commercially reasonable efforts to obtain
an extension of time for submission of such plan) of the receipt thereof (it
being understood that if the Seller does not provide any such comments, the
Purchaser may proceed with performance of such Remediation), after which the
Purchaser shall provide the final Remediation plan to the Seller for the
Seller's approval, which approval may not be unreasonably withheld or delayed.





                                                                              82

                           (iii)    Remediation of Leased Real Property. In the
event that an Action is commenced against the Purchaser after the Closing
relating to a Known Environmental Liability on a Leased Real Property:

                                    (A)      If such Known Environmental
         Liability is not identified as having been caused by the Seller, the
         Purchaser shall first demand indemnification from the lessor of the
         Leased Real Property for any liability relating to the Known
         Environmental Liability. The Purchaser shall thereafter seek in good
         faith to obtain such indemnification from such lessor; provided,
         however, if such lessor refuses or fails to assume the defense of the
         matter and to indemnify the Purchaser for all losses related to the
         matter, the Purchaser may require the Seller to provide such
         indemnification as would otherwise be available under this Section 14.
         In such applicable circumstances, the Purchaser shall assign to the
         Seller all rights it has under the lease and at Law to recover from the
         lessor any losses relating to the Known Environmental Liability in
         question.

                                    (B)      If such Known Environmental
         Liability is identified as having been caused by the Seller, all of the
         obligations of the Seller with respect to indemnification of the
         Purchaser for such matters under this Section 14 shall apply.

         14.5     Indemnification of the Seller by the Purchaser. Subject to
Sections 14.6 and 14.7 hereof, the Purchaser agrees to defend, indemnify and
hold harmless the Seller and its Affiliates and their respective officers,
directors, agents and representatives and the respective successors and
permitted assigns of each of the foregoing (the "Seller Indemnitees") against
and in respect of any Losses incurred by the Seller Indemnitees to the extent
resulting or arising from:

                  (a)      a breach of any of the representations or warranties
made by the Purchaser in Section 6 of this Agreement or in the certificate
delivered pursuant to Section 9.3;

                  (b)      a breach of any of the covenants or agreements (other
than the Transaction Documents or the covenants or agreements contained in
Section 7.2(a) through (g)) made or to be performed by the Purchaser or its
successors pursuant to this Agreement;

                  (c)      (i) any liability or obligation (other than Excluded
Liabilities) of any nature or kind, known or unknown, fixed, accrued, absolute
or contingent, or any claim, demand or condition asserted with respect to the
Purchaser's operation of the Purchased Assets arising out of events occurring on
or after the Closing Date or (ii) any Assumed Liability; or

                  (d)      any liability or obligation (including Environmental
Liabilities) with respect to the Purchaser's operation of real property subject
to a Seller Real Property Lease or the Seller Real Property Sublease on or after
the Closing Date.

         The obligations of the Purchaser hereunder shall bind the successors
and assigns of the Purchaser.

         For all purposes of this Section 14.5, a breach of the Purchaser's
representations and warranties shall be determined without regard to any
limitation or qualification as to





                                                                              83

"materiality", "material", "materially" or "material adverse effect" set forth
in such representation or warranty.

         14.6     Duration of Indemnification of the Seller. The Purchaser's
respective obligations to defend, hold harmless and indemnify the Seller
Indemnitees under Section 14.5 shall apply only to any Claim Notice given
pursuant to Section 14.8 within the following periods:

                  Section 14.5(a)   Eighteen (18) months after the Closing Date,
                                    except that the Purchaser's indemnification
                                    obligation with respect to a breach of any
                                    representation or warranty contained in
                                    Sections 6.1 or 6.2 shall survive until the
                                    expiration of the applicable statute of
                                    limitations.

                  Section 14.5(b)   Eighteen (18) months after the Closing Date
                                    with respect to covenants and agreements of
                                    the Purchaser that by their terms are to be
                                    performed in full prior to or on the Closing
                                    Date.

                                    No time limit with respect to covenants and
                                    agreements of the Purchaser that by their
                                    terms are to be performed or completed after
                                    the Closing Date.

                  Section 14.5(c)   No time limit, provided that the Purchaser's
                                    indemnification obligation with respect to
                                    any claims in respect of Taxes shall survive
                                    until the expiration of the applicable
                                    statute of limitations.

                  Section 14.5(d)   Twelve (12) months after the date on which
                                    Purchaser ceases to operate the property
                                    subject to a Seller Real Property Lease or
                                    the Seller Real Property Sublease.

         14.7     Limitation on Indemnification of the Seller. The Purchaser's
obligation to defend, indemnify and hold harmless the Seller Indemnitees (i)
under Section 14.5(a) shall apply only after the Seller Indemnitees have
suffered Losses under Section 14.5(a) in excess of the Minimum Amount, after
which the Purchasers shall only be obligated to indemnify Losses in excess of
such amount; and (ii) in any case shall apply only after the amount of any
individual or any series of related Losses indemnified against hereunder shall
exceed fifty thousand dollars ($50,000) and then shall apply to the entire
amount of such Loss. The Purchaser will be obligated only to indemnify Losses
relating to breaches of representations and warranties in excess of the Minimum
Amount and up to an aggregate amount equal to the Maximum Amount.
Notwithstanding the foregoing provisions of this Section 14.7, the Purchaser
shall be entitled to receive indemnification payments in respect of the
indemnification payments under Sections 14.5(b), (c) and (d) without regard to
the individual or aggregate amount thereof and without regard to whether the
aggregate amount of all other indemnification payments shall have exceeded, in
the aggregate, the Minimum Amount or shall have exceeded, in the aggregate, the
Maximum Amount. Any claim which is within the description of Section 14.5(a) or
14.5(b),





                                                                              84

which is also within the description of any of Sections 14.5(c) and 14.5(d),
shall be deemed to be asserted and treated hereunder for all purposes as a claim
arising out of Sections 14.5(c) and 14.5(d), as appropriate.

         14.8     Procedure for Indemnification. After a party becomes aware
that any claim is threatened or asserted against it or the existence of any
other circumstances that would occasion the indemnification described in this
Section 14 (a "Covered Claim"), such party shall provide the party from whom it
is seeking indemnification with a notice (a "Claim Notice") of such Covered
Claim pursuant to the provisions of Section 20 hereof. Failure to give such
notice promptly shall not relieve the Assuming Party (defined below) of its
indemnification obligations hereunder except to the extent it actually is
prejudiced by such failure. Each Claim Notice shall describe the Covered Claim,
the party threatening or asserting it (if applicable), the relief sought, and
the basis for indemnification hereunder with respect thereto. In the case of a
third-party claim, the party receiving such notice may, at its option, assume
the defense of such Covered Claim (the "Assuming Party"); provided, that, within
forty (40) days after the Claim Notice is given (or sooner, if the nature of the
Covered Claim so requires), the party receiving such notice shall have given
notice to the other party (the "Notifying Party"), pursuant to the provisions of
Section 20 hereof, of its election to assume such defense. If the defense is so
assumed by the Assuming Party with counsel reasonably acceptable to the
Notifying Party, the Notifying Party shall be entitled to participate in the
defense of the Covered Claim with its own counsel at its own expense, and the
Notifying Party shall provide such cooperation at the expense of the Assuming
Party (including providing available information and personnel to the Assuming
Party) as the Assuming Party shall reasonably request to facilitate such
defense. The Assuming Party shall have the right to defend and/or settle any
such Covered Claim on such terms and conditions and in such amounts as it deems
appropriate, and the Notifying Party shall promptly execute all documents
reasonably requested of it with respect to any such defense and/or settlement;
provided, however, any such settlement shall include an unconditional release by
the claimant of all indemnified persons with respect to such Covered Claim and
the indemnified persons shall not be required to take any action other than the
delivery of such release. If the party receiving the notice does not assume the
defense of a given Covered Claim pursuant hereto or fails to notify the
Notifying Party of its election hereunder or contests its obligation to
indemnify under this Agreement, or if the third party seeks remedies in addition
to the monetary damages, the party giving the notice shall defend against such
Covered Claim in such manner, and/or settle such Covered Claim on such terms, as
it shall, in its sole reasonable judgment, determine to be appropriate under the
circumstances and such action shall be binding on the parties for the purposes
of this Section 14. Notwithstanding the preceding sentence, no party may settle
or compromise any Covered Claim over the objection of the other. Notwithstanding
the foregoing, in any action or proceeding in which the counsel chosen by the
Notifying Party determines that counsel chosen by the Assuming Party cannot
represent both the Notifying Party and the Assuming Party in connection with the
defense of any Covered Claim consistent with the applicable rules of
professional conduct, the Notifying Party shall have the right to employ
separate counsel at the Notifying Party's expense and to control its own defense
in connection therewith.

         14.9     Payment Limitation. Payments by the Seller pursuant to Section
14.2, or by the Purchaser pursuant to Section 14.5, as the case may be, shall be
limited to the amount of any loss





                                                                              85

or damage that remains after deducting therefrom (i) any Tax Benefit to the
Purchaser Indemnitee or Seller Indemnitee, as the case may be, and (ii) any
insurance proceeds and any indemnity, contribution or other similar payment
recoverable by the Purchaser Indemnitee or Seller Indemnitee, as the case may
be, from any Third Party with respect thereto. A Tax Benefit will be considered
to be recognized by the Purchaser Indemnitee or Seller Indemnitee, as the case
may be, for purposes of this Section 14.9 in the Tax period in which the
indemnity payment occurs, and the amount of the Tax Benefit shall be determined
by assuming that the Purchaser Indemnitee or Seller Indemnitee, as the case may
be, is in the maximum applicable statutory tax bracket after any deductions or
other allowances reportable with respect to a payment hereunder.

         14.10    Exclusive Remedy. Subject to Section 17, the Parties hereby
acknowledge and agree that their sole and exclusive remedy with respect to any
and all claims relating to the subject matter of this Agreement shall be
pursuant to the indemnification provisions set forth in this Section 14 (other
than with respect to the Transaction Documents and the remedies provided for
therein and other than claims of, or causes of action arising from, fraud). In
furtherance of the foregoing, the Parties hereby waive, to the fullest extent
permitted under applicable Law, any and all rights, claims and causes of action
it may have against the Seller (other than with respect to the Transaction
Documents and the remedies provided for therein and other than claims of, or
causes of action arising from, fraud) arising under or based upon any breach of
a representation or warranty contained herein other than the remedies expressly
provided in this Section 14.

         14.11    Exceptions. The Seller shall have no liability under any
provision of this Agreement for any losses and damages to the extent that such
losses and damages are caused by actions taken by the Purchaser and its
Affiliates after the Closing Date. In no event shall any Party be liable for
consequential, special, indirect, incidental or punitive damages, except to the
extent special, indirect, consequential or punitive damages are awarded to a
third party against an Indemnified Party in circumstances in which such
Indemnified Party is entitled to indemnification hereunder.

                      SECTION 15. TERMINATION OF AGREEMENT

         15.1     Events of Termination. This Agreement and the transactions
contemplated hereby may be terminated or abandoned at any time prior to the
Closing Date as follows:

                  (a)      upon the written agreement of the Seller and the
Purchaser;

                  (b)      at the election of the Purchaser, if (i) the Seller
has breached any representation or warranty contained in this Agreement that is
qualified by materiality or a Business Material Adverse Effect requirement, (ii)
the Seller has breached in any material respect any representation or warranty
contained in this Agreement that is not so qualified, (iii) the Seller has
breached any covenant or agreement contained in this Agreement that is qualified
by materiality or a Business Material Adverse Effect requirement, or (iv) the
Seller has breached in any material respect any covenant or agreement contained
in this Agreement that is not so qualified, in the case of (i), (ii), (iii) or
(iv), which breach has been notified to the Seller in writing by the Purchaser
and cannot been cured on or prior to the date set forth in Section 15.1(f),
provided that if the Seller is not using its commercially reasonable efforts to
so cure, on the date that is thirty (30) days following delivery of such written
notice;





                                                                              86

                  (c)      at the election of the Seller, if (i) the Purchaser
has breached any representation or warranty contained in this Agreement that is
qualified by materiality or material adverse effect or (ii) if the Purchaser has
breached in any material respect any representation or warranty contained in
this Agreement that is not so qualified, (iii) the Purchaser has breached any
covenant or agreement contained in this Agreement that is qualified by
materiality or material adverse effect, or (iv) the Purchaser has breached in
any material respect any covenant or agreement contained in this Agreement that
is not so qualified, in the case of (i), (ii), (iii) or (iv) which breach has
been notified to the Purchaser in writing by the Seller and cannot been cured on
or prior to the date set forth in Section 15.1(f), provided that if the
Purchaser is not using its commercially reasonable efforts to so cure, on the
date that is thirty (30) days following delivery of such written notice;

                  (d)      at the election of the Purchaser or the Seller in
accordance with Section 8.12;

                  (e)      at the election of the Purchaser or the Seller in
accordance with Section 7.9(d)(iii);

                  (f)      upon written notice by either the Seller or the
Purchaser, if the Closing Date shall not have occurred before October 29, 2004,
for any reason other than (i) the failure of the party seeking to terminate this
Agreement to perform its obligations hereunder or (ii) a breach of a
representation or warranty by such party herein, in each case that would give
the other party the right to terminate the Agreement; or

                  (g)      upon written notice by the Purchaser, if, after the
date hereof, there shall have occurred a Business Material Adverse Effect.

         15.2     Consequences of Termination. If this Agreement shall be
terminated pursuant to 15.1, this Agreement shall thereafter become void and
neither party shall have any further obligation to the other hereunder, except
as set forth in Sections 7.6, 10.5, 11, 12 and this Section 15.2; provided,
however, that

                  (a)      (i) if the Seller shall have the right to terminate
this Agreement pursuant to any of Sections 15.1(c)(i) or 15.1(c)(ii), where such
breach was caused with an intent to mislead or defraud, or Section 15.1(c)(iii)
or Section 15.1(c)(iv), or (ii) if the Purchaser shall have the right to
terminate this Agreement pursuant to any of Sections 15.1(b)(i) or 15(b)(ii),
where such breach was caused with an intent to mislead or defraud, or Section
15.1(b)(iii) or Section 15.1(b)(iv), it is expressly understood and agreed that,
subject to Sections 15.2(b) and 15.2(c), the terminating party's right to pursue
all legal remedies for breach of contract and damages shall survive such
termination unimpaired; provided, however, that no party shall have any remedy
for the breach of any covenant or agreement contained in Section 7.2(a) through
(g) and each party expressly waives and disclaims any claim based on any such
breach;

                  (b)      except as set forth in Section 15.2(a), prior to the
Closing Date, the sole and exclusive rights and remedies of either party for and
with respect to breach of representations and warranties of the other party
under this Agreement, which shall occur prior





                                                                              87

to the Closing Date, and are known to such party, shall be to terminate this
Agreement to the extent permitted by, and in accordance with, Section 15.1; and

                  (c)      notwithstanding anything to the contrary contained in
this Agreement, upon termination of this Agreement in accordance with Section
15.1(d), the Purchaser shall pay to the Seller (i) an amount equal to $5,000,000
in the event that this Agreement is terminated in connection with the occurrence
of a Financing Extension Condition that arises from or relates to an Financial
Market Non-Funding Condition or (ii) an amount equal to $10,000,000 in the event
that this Agreement is terminated in connection with the occurrence of a
Financing Extension Condition that arises from or relates to an Other
Non-Funding Condition (such payment under clause (i) or clause (ii), as
applicable, the "Termination Payment"), as liquidated damages, in immediately
available funds by wire transfer to such account as the Seller shall designate
in writing to the Purchaser and Purchaser shall have no further liability or
obligation to the Seller relating to or arising from this Agreement; provided,
that in the event that any of the conditions to Closing set forth in Sections
8.1, 8.2, 8.3, 8.4, 8.7 and 8.10 hereof are not satisfied as of the time that
the Termination Payment is required to be paid (other than those which by their
nature are to be satisfied at the Closing), the Purchaser shall not be required
to make the Termination Payment in connection with such termination, but the
Purchaser shall have no further liability or obligation to the Seller relating
to or arising from this Agreement.

            SECTION 16. CONSENT TO JURISDICTION; SERVICE OF PROCESS;
                    DISPUTE RESOLUTION; WAIVER OF JURY TRIAL

         16.1     General Disputes. Except with regard to Factual Environmental
Disputes (as defined below), which are exclusively covered by Section 16.2
below:

                  (a)      The Seller, on one hand, and the Purchaser, on the
other hand, shall attempt in good faith to resolve any dispute, controversy or
claim between them arising out of or relating to this Agreement, including any
dispute over the breach, termination, interpretation, or validity hereof (the
"Dispute"). Each party may request through written notice that the Dispute be
referred to senior executives of the parties who have authority to resolve the
Dispute. The executives shall attempt to resolve the Dispute by agreement within
thirty (30) days of such notice. In attempting to resolve the Dispute the
parties shall not be waiving and shall not be deemed to have waived any rights
which they may have under this Agreement or otherwise as a result of the
resolution of a Dispute pursuant to this Section 16.1;

                  (b)      If the parties to the Dispute are unable to resolve
the Dispute as provided in Section 16.1(a), then the Dispute shall be resolved
in accordance with this Section 16.1(b) unless the parties otherwise agree to an
alternative dispute resolution procedure. All Actions arising out of or relating
to the Transaction Documents shall be heard and determined exclusively in any
New York federal court sitting in the Borough of Manhattan of The City of New
York; provided, however, that if such federal court does not have jurisdiction
over such Action, such Action shall be heard and determined exclusively in any
New York state court sitting in the Borough of Manhattan of The City of New
York. Consistent with the preceding sentence, the parties hereto hereby (a)
submit to the exclusive jurisdiction of any federal or state court sitting in
the Borough of Manhattan of The City of New York for the purpose of any Action
arising out of or relating to this Agreement brought by either party hereto and





                                                                              88

(b) irrevocably waive, and agree not to assert by way of motion, defense, or
otherwise, in any such Action, any claim that it is not subject personally to
the jurisdiction of the above-named courts, that its property is exempt or
immune from attachment or execution, that the Action is brought in an
inconvenient forum, that the venue of the Action is improper, or that this
Agreement or the transactions contemplated by this Agreement may not be enforced
in or by any of the above-named courts.

                  (c)      EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS
AGREEMENT. EACH OF THE PARTIES HERETO HEREBY (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO
ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT,
AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN
THIS SECTION 16.1(c).

                  (d)      Any and all service of process and any other notice
in any such claim shall be effective against any party if given personally or by
registered or certified mail, return receipt requested, or by any other means of
mail that requires a signed receipt, postage prepaid, mailed to such party as
herein provided. Nothing herein contained shall be deemed to affect the right of
any party to serve process in any manner permitted by Law.

         16.2     Factual Environmental Disputes.

                  (a)      If the parties do not agree concerning a particular
factual matter that is relevant to a determination of any party's rights and/or
obligations under this Agreement with respect to any environmental matter (a
"Factual Environmental Dispute"), and if it is necessary to resolve such factual
dispute in order to establish any rights and/or obligations under this
Agreement, the parties shall endeavor, using good faith efforts (and relying on
environmental consultants and/or other technical experts, where appropriate), to
negotiate a mutually satisfactory resolution to the Factual Environmental
Dispute. In the event that the parties are unable to resolve such Factual
Environmental Dispute within thirty (30) Business Days after one party first
contacts the other party to attempt to resolve the Factual Environmental Dispute
in question (or, if the parties mutually agree to waive this initial thirty (30)
Business Day period):

                                    (A)      The parties shall mutually agree on
         one person who has the technical background and expertise necessary to
         resolve the Factual Environmental Dispute (a "Technical Expert"); or,
         failing such agreement, each party shall designate one such Technical
         Expert, and within fifteen (15) Business Days after both Technical
         Experts are so designated, those two Technical Experts shall designate
         a third Technical Expert (which such third Technical Expert shall not
         be a current or former employee or agent of either party or of their
         respective Technical Experts); and





                                                                              89

                                    (B)      Within thirty (30) Business Days
         after designation of the Technical Expert(s), such Technical Expert(s)
         shall independently consider all information relevant to the
         determination and resolution of the Factual Environmental Dispute, each
         party having a reasonable opportunity to provide timely input to the
         Technical Expert(s), and shall make a single recommendation (including
         a good faith estimate of the cost to implement the recommendation) to
         the parties regarding the factual matter(s) that is the subject of
         dispute (with a vote of two being necessary to reach this
         recommendation if three Technical Experts have been designated). In the
         event that the estimated cost to implement the recommendation of the
         Technical Expert(s) is: (i) less than $100,000, the recommendation
         shall be exclusive, final and binding upon the parties as to the
         factual matters thereby addressed; and (ii) equal to or greater than
         $100,000, the recommendation shall be not be exclusive, final and
         binding upon the parties as to factual matters thereby decided.

                  (b)      The parties shall share the costs and expenses of the
Technical Expert(s) equally.

                  SECTION 17. ENFORCEMENT OF CERTAIN PROVISIONS

                  (a)      The parties acknowledge and agree that if any party
breaches any provision of this Agreement applicable to such party, any remedy at
law would be inadequate and insufficient and would cause the non-breaching party
irreparable harm and that the non-breaching party, in addition to seeking
monetary damages in connection with any such breach, shall be entitled to
specific performance and injunctive and other equitable relief to prevent or
restrain a breach of this Agreement or to enforce the provisions of this
Agreement without the requirement of posting bond or other security.

                  (b)      If any of the covenants contained in any of Sections
7.6, 7.7, 7.8 or 10.5, or any part thereof, is hereafter construed to be invalid
or unenforceable, the same shall not affect the remainder of the covenant or
covenants, which shall be given full force and effect, without regard to the
invalid portions. If any of the covenants contained in any of Sections 7.6, 7.7,
7.8 or 10.5, or any part thereof, is held by a court of competent jurisdiction
to be unenforceable because of the duration of such provision or the geographic
area covered thereby or for any other reason, the parties agree that the court
making such determination shall have the power to reduce the duration and/or
geographic area of such provision or otherwise modify the terms of any such
covenant and, in its reduced form, said provision shall then be enforceable;
provided, however, that any such reduction or modification shall apply only with
respect to the operation of such Section in the jurisdiction of such court.

                           SECTION 18. BULK SALES LAW

         Subject to Section 14.2(f), the Purchaser hereby waives compliance by
the Seller with the provisions of the bulk sales Law of any state, including
with respect to Tax.





                                                                              90

                        SECTION 19. PUBLIC ANNOUNCEMENTS

         No press release or other public announcement, or communication with
any news media, shall be made by or on behalf of any party hereto concerning
this Agreement or the transactions contemplated hereby without providing prior
written notice thereof to the other party, except as may be required by
applicable Law or the regulations or listing rules of any securities exchange.
The parties shall cooperate as to the timing and contents of any such press
release, public announcement or communication.

                               SECTION 20. NOTICES

         All notices and all other communications hereunder shall be in writing
and shall be deemed given if delivered personally or sent by registered or
certified mail, postage prepaid (return receipt requested), sent by facsimile

EXHIBIT K

Note: Pursuant to a request submitted to the Securities and Exchange Commission
for confidential treatment, portions of sections 8.1 and 8.2 of the LOX/LIN/LAR
Products Supply Agreement were omitted. The omitted information is marked with
brackets and asterisks [**]. The omitted information has been filed separately
with the Securities and Exchange Commission.

                      LOX/LIN/LAR PRODUCTS SUPPLY AGREEMENT

         This Product Supply Agreement (the "AGREEMENT") is made as of July 30,
2004 (the "EFFECTIVE DATE"), between The BOC Group, Inc. ("SELLER"), with its
headquarters at 575 Mountain Avenue, Murray Hill, New Jersey 07974, and Airgas,
Inc., with its headquarters at 259 N. Radnor-Chester Road, Suite 100, Radnor,
Pennsylvania 19087 ("BUYER").

1.       Sale and Purchase.

         1.1 A    Reserved Volumes. Seller currently operates industrial gas
production facilities (each a "PLANT") in Claymont, DE, Bethlehem, PA, Kittery,
ME, Buffalo, NY, and Selkirk, NY (such locations collectively the "EASTERN
CONFERENCE"); Indianapolis, IN, Fostoria, OH, Hartford, IL, and LaPorte, IN
("Springville"), Braddock, PA, and Arroyo, WV (such locations collectively the
"MIDWEST CONFERENCE"); Nashville, TN, Aiken, SC, Birmingham, AL, and Midland, NC
(such locations collectively the "SOUTHEAST CONFERENCE"), Dallas, TX , Geismar,
LA , and Enid OK (such locations collectively the "SOUTHWEST CONFERENCE"),
Sacramento, CA, City of Industry, CA, Vancouver, WA and Trail, BC(such locations
collectively the " WESTERN CONFERENCE"). Commencing on the date hereof, and
continuing throughout the Term (as defined in Section 3), Seller agrees to sell
to Buyer from each of the Plants listed above, up to that volume per month of
liquid nitrogen ("LIN"), liquid oxygen ("LOX") and liquid argon ("LAR"); and
(LIN, LOX and LAR individually a "PRODUCT" and collectively the "PRODUCTS") as
is indicated on Attachment A attached hereto, as such volumes may be adjusted in
accordance with the terms of this Agreement (such volumes of Products, as so
adjusted, as to any Product, as to any Plant and/or as to any Conference, as
applicable, the "RESERVED VOLUMES"). Seller has no responsibility to provide
volumes above the Reserved Volumes.

         1.1B     Volumes of Product taken under this Agreement will not be
considered applicable towards any other agreement between Buyer and Seller.

         1.2      Right to Purchase. Commencing on the date hereof and
continuing through the Term, Buyer, directly or through one or more of its
direct or indirect operating subsidiaries



("SUBSIDIARIES"), shall have the right to purchase from Seller each month up to
the Reserved Volume of each Product at each Plant for use at their cylinder
filling facilities. Buyer may move Product to sites other than cylinder filling
facilities, subject to the conditions in Section 1.3.

         1.3      Adjustments to Reserved Volumes.

                  (a)      By written notice to Seller given no less than sixty
(60) days prior to September 30, 2005, September 30, 2008, September 30, 2011
and/or September 30, 2014, and, subject to the consent of Seller not to be
unreasonably withheld, more frequently by mutual agreement, Buyer may (i)
reallocate volumes of any or all Products from Plant to Plant within a
Conference and/or (ii) reallocate up to twenty-five percent (25%) of the actual
volumes (defined as the average monthly purchase amounts for the prior 12 month
period) from the Reserved Volumes of any or all Products for Plants within one
or more Conferences immediately prior to such reallocation to other Plants in
other Conferences. At least 50% of the moved volumes must be transferred to
another Buyer cylinder filling facility. Volumes moved to other Seller plants
are subject to the consent of Seller, not to be unreasonably withheld.

         1.4      Ancillary Services. In addition to the Products to be supplied
under this Article 1, Seller, if so requested by Buyer or a Subsidiary, also
agrees to provide Buyer or such Subsidiary the ancillary services described in
Attachment F (each an "ANCILLARY SERVICE" and collectively the "ANCILLARY
SERVICES").

2.       Take or Pay.

         2.1      Reporting. On or before the 15th day of each month during the
Term, Seller shall provide Buyer with a written report by Plant and Product
showing the amount of each Product purchased by Buyer from each Plant during the
previous calendar month (each a "MONTHLY REPORT" and collectively the "MONTHLY
REPORTS") under this Agreement. For purposes of this Agreement, Products
purchased by Buyer hereunder shall be deemed to have been purchased from the
Plant closest to the point of delivery of such Product. The parties shall use
good faith efforts to promptly resolve any disputes regarding the Monthly
Reports and any dispute that cannot be amicably resolved may be submitted by
either party for Dispute Resolution as provided in Section 16.3 hereof.

         2.2      Shortfall Amounts. Every six months ("SIX MONTH PERIOD"),
Seller shall give Buyer written notice of the amount by which Buyer's purchases
of Products during the

                                        2


immediately preceding Six Month Period fell short of the following minimum
amounts (the "TAKE-OR-PAY MINIMUMS"):

         By Conference -

                  85% of the aggregate volumes in Attachment I of LOX and LIN
                  combined for such Conference for such Six Month Period.

                  85% of the aggregate volumes in Attachment I of LAR for such
                  Conference for such Six Month Period.

         Each such shortfall is referred to herein as a "Conference Take-or Pay
Shortfall Amount". Buyer can one time reduce the Take-or-Pay Minimums by 20%
from the Take-or-Pay Minimums then in effect (the "Adjustment") should Buyer
experience an extraordinary loss of volume due to economic or market conditions;
provided, that Buyer may not elect the Adjustment until five years later than
the initial date of this Agreement. The Adjustment will be rescinded when the
Buyer's volumes have returned to approximately their prior levels.

         2.3      Shortfall Payments. Buyer agrees either to (A) purchase the
amount of the Conference Take or Pay Shortfall Amount in the subsequent Six
Month Period, in which case, volumes each month in the subsequent Six Month
Period shall apply (i) first to one sixth (1/6th) of the Take or Pay Minimums
for the current Six Month Period, and then, to the extent such 1/6th of the Take
or Pay Minimum is satisfied, (ii) second, towards the Take or Pay Shortfall
Amount from the prior period, or (B) pay Seller 50% of the Conference
Take-or-Pay Price (as determined below) for all Conference Take-or-Pay Shortfall
Amounts. The Conference Take-or-Pay Prices for LOX and LIN, taken together, and
for LAR shall be equal to the weighted average Base Price of the LOX and LIN,
taken together, purchased by Buyer from Plants in such Conference during the Six
Month Period in which Buyer failed to purchase the Take-or-Pay Minimums and the
weighted average Base Price of the LAR purchased by Buyer from Plants in such
Conference during such Six Month Period. Any such shortfall will be billed
following the conclusion of the applicable Six Month Period. The Take or Pay
Shortfalls will be billed (if applicable) beginning with the second Six Month
Period of the Agreement.

3.       Term. The term of this Agreement shall commence on the Effective Date
and shall continue for a period of 15 years therefrom, on which date this
Agreement shall automatically terminate (the "TERM").

                                        3


4.       Buyer's Obligations.

         Buyer shall, without cost to Seller,

                  (a)      Provide sufficient physical access to areas in which
storage vessels are located to Seller and Seller's authorized representatives
for all proper purposes under this Agreement; and

                  (b)      Comply with all relevant reporting obligations under
the Emergency Planning and Community Right-To-Know Act of 1986, 42 U.S.C.
Section 11001-11050 (EPCRA, also commonly known as Title III of the Superfund
Amendments and Reauthorization Act of 1986 (SARA Title III)) resulting from the
presence of the chemicals supplied under this Agreement. Further, it is the
responsibility of Buyer to warn its employees and others exposed to the hazards
posed by Buyer's storage and use of Products and to comply with all federal,
state and local legal notification, reporting and/or permit requirements that
may be associated with the storage or use of a Product.

                  (c)      Provide storage vessels in satisfactory condition for
safe operation with cryogenic materials as commonly defined by the industry as
well as 1) evidence that annual inspections have been completed on said storage
vessels, 2) LOX deliveries must be on a concrete pad, 3) acceptable access for
Seller's delivery vehicles, 4) LOX tanks cannot have aluminum inner linings, and
5) storage vessels must have dual safety valves and rupture discs.

5.       Specifications; Standards of Performance.

         All Products delivered by Seller shall conform to the applicable
specifications set forth in Attachment G (the "SPECIFICATIONS"). All Ancillary
Services performed by Seller shall be performed in a workmanlike fashion.

6.       Delivery.

         6.1      Delivery of Products. Product shall be delivered by Seller
F.O.B. Seller's delivery vehicle, if the delivery vehicle is supplied by Seller,
or F.O.B. Buyer's delivery vehicle, if the delivery vehicle is supplied by
Buyer. Risk of loss shall pass to Buyer upon delivery to Buyer's facility, if
delivery is made in Seller's vehicle, or to Buyer's delivery vehicle, if
delivery is made in Buyer's vehicle. Buyer shall have the right, with a minimum
of 7 days advance written notice, to observe Seller's normally scheduled
calibration of meters on Seller's delivery vehicles. In the event that Buyer has
concerns regarding the calibration of a specific meter on one of the

                                        4


Buyer's vehicles beyond a normal variance of +/- 2.5% or regular significant
variance in the same direction, Buyer will provide documentation regarding its
concerns on the specific meter to the Seller and shall have the right, with a
minimum of 7 days advance written notice, to require and observe the performance
of meter calibration on the particular unit in question. Seller will use
commercially reasonable efforts to deliver Products so as to avoid customer
run-outs and will use commercially reasonable efforts to deliver LOX and LIN
within twenty-four (24) hours' and LAR within forty-eight (48) hours' of
receiving notice of a requested delivery. If Seller fails to make timely
delivery of Product such that Buyer, or a customer of Buyer, experiences
interruption of supply or if interruption of supply appears imminent (Buyer to
obtain confirmation from a Scheduling Supervisor or Manager of Seller's National
Operations Center, as noted in Attachment J), Buyer may purchase the Product
Seller has failed to deliver from a third party. Seller shall pay Buyer the
difference between the cost to Buyer of purchasing such alternative Product and
the cost of such Product under this Agreement. Such purchases shall be applied
to the applicable Take-or-Pay Minimums as though they had been made from Seller.
Such remedy shall be in addition to, and not in lieu of, any other remedy Buyer
may have under this Agreement. Such Product shall be deemed to have been
purchased from Seller for purposes of determining whether Buyer has purchased
the applicable Reserved Volumes of such Product.

         6.2      Notice of Requirements. Buyer shall monitor its inventory of
Product and give reasonable notice, in accordance with Section 6.1, of the
quantity of Product needed to permit delivery prior to exhaustion of such
inventory; provided, however, that if Buyer or, with Buyer's consent, Seller
installs telemetry, Seller shall be solely responsible for such monitoring.
Buyer will use commercially reasonable efforts to provide notice of significant
changes in use so Seller can adequately monitor such inventory.

7.       Prices and Charges for Products and Services.

         7.1      Prices. The price for Product sold shall be comprised of a
"BASE PRICE", and a "DISTRIBUTION COST" (when Product is delivered by Seller,
calculated in accordance with Attachments B and C), and shall be subject to
adjustment as provided herein (collectively the "PRICE"). The Base Price for a
Product shall be the amount for such Product set forth on Attachment B, as
appropriate, and shall be subject to adjustment as provided in Attachment E.

         7.2      Surcharges.

                                        5


                  (a)      If during any Contract Year a Plant of Seller
providing Products hereunder experiences an extraordinary increase in its truck
fuel costs or power costs and such extraordinary cost increases are likewise
being experienced by a majority of the other producers in the industry within
three hundred (300) miles of such Plant, Seller, after giving 30 days written
notice to Buyer, may charge Buyer and Buyer shall pay a surcharge (a
"SURCHARGE") in an amount no greater than the amount required for Seller to
recover such increased costs. For purposes of the first Surcharge imposed with
respect to truck fuel costs and the first Surcharge imposed with respect to
power costs, an "extraordinary increase" shall be defined as an increase of at
least 25% as compared to the average cost for such item of cost in the previous
calendar quarter. A Surcharge shall remain in effect until the earlier of (i)
date upon which Seller's costs return to an amount comparable to what they were
prior to such extraordinary increase in its costs, or (ii) the date upon which
the costs of other producers in the industry within three hundred (300) miles of
such Plant return to an amount comparable to what they were prior to such
extraordinary increase in their costs. In addition, as costs are reducing to
such prior levels, Seller shall make reasonable periodic reductions in the
Surcharge. Prior to imposing a Surcharge under this Section 7.2, Seller shall
provide Buyer with evidence supporting the need for the Surcharge. If Buyer
disputes said Surcharge, Buyer may, at its own cost, hire an independent
auditor, to whom Seller has no reasonable objection, to document validity of
said surcharge. If the Surcharge is not deemed valid by the auditor based on the
aforementioned increased costs, Seller will not implement any such surcharge and
provided Seller concurs with the auditor, will be responsible for paying the
independent auditor. If Seller does not agree with the conclusions of the
auditor, Seller may invoke the provisions of Section 16.3 in order to resolve
the dispute.

                  (b)      If during any Contract Year a Plant of Seller
providing Products hereunder experiences extraordinary cost increases in its
truck fuel costs or power costs but such extraordinary cost increases are not
being experienced by a majority of the other producers in the industry within
three hundred (300) miles of such Plant, Seller, by giving written notice to
Buyer (a "SELLER SPECIFIC SURCHARGE NOTICE"), may advise Buyer that it is going
to charge Buyer a surcharge (a "SELLER SPECIFIC SURCHARGE") in an amount no
greater than the amount required for Seller to recover such increased costs.
Concurrently with its delivery of a Seller Specific Surcharge Notice, Seller
shall provide Buyer with evidence supporting the need for the Seller Specific
Surcharge. Buyer, within thirty (30) days after receiving a Seller Specific
Surcharge Notice, may, by written

                                        6


notice to Seller ("BUYER REFUSAL NOTICE"), refuse to accept the Seller Specific
Surcharge. Seller, upon receipt of a Buyer Refusal Notice, may either (a)
refrain from charging the Seller Specific Surcharge or (b) within ten (10) days
after receiving the Buyer Refusal Notice, give Buyer written notice that Seller
will no longer supply Products to Buyer from the affected Plant (a "SELLER
TERMINATION NOTICE"). If Seller sends Buyer a Seller Termination Notice, Buyer
shall no longer be required to purchase any Products from such Plant and the
Reserved Volumes and Take-or-Pay Minimums shall be adjusted accordingly. If
Buyer does not deliver a Buyer Refusal Notice, the Seller Specific Surcharge
shall remain in effect until the date upon which Seller's costs return to an
amount comparable to what they were prior to such extraordinary increase in its
costs. In addition, as costs are reducing to such prior levels, Seller shall
make reasonable periodic reductions in the Seller Specific Surcharge. If Buyer
disputes said Surcharge, Buyer may, at its own cost, hire an independent
auditor, to whom Seller has no reasonable objection, to document validity of
said surcharge. If the surcharge is not deemed valid by the auditor based on the
aforementioned increased costs, Seller will not implement any such surcharge and
provided Seller concurs with the auditor, will be responsible for paying the
independent auditor. If Seller does not agree with the conclusions of the
auditor, Seller may invoke the provisions of Section 16.3 in order to resolve
the dispute.

                  (c)      Any Surcharge or Seller Specific Surcharge shall be
one that Seller is applying generally to its customers and not one applicable to
Buyer alone. Surcharges and Seller Specific Surcharges shall be in addition to
the Price and neither the assessment of nor changes in such Surcharges and
Seller Specific Surcharges shall be construed as a Price adjustment under
Section 8.1; provided, however that there shall be no duplication of Price
adjustments and Surcharges or Seller Specific Surcharges hereunder.

8.       Adjustments in Prices.

         8.1      Adjustments. The Price of each Product will be adjusted on
[**] as outlined in Attachment E. Distribution Matrices will also be adjusted
[**], as outlined in Attachment E. Notwithstanding the foregoing, in [**], Buyer
shall have the right to furnish written evidence (the "QUOTED PRICE") to Seller
(which Quoted Price may be either FOB Seller's Plant or a delivered price), at
least 60 days prior to [**] and at least 60 days prior to [**], of its ability
to purchase one or more Products for one or more Plants and/or one or more
Conferences from one or more responsible suppliers thereof, for a term of not
less than [**], in like quantity and quality and by

                                        7


like delivery with similar terms and conditions as compared to the quantity and
quality and delivery method for such Product Seller is then delivering to Buyer
for such Plants(s) and/or Conference(s) under this Agreement, at a lower price
than Seller's then-current Price. The comparison will be the difference in
delivered prices and not solely FOB prices, with reasonable allowances for
situations where Buyer product distribution is via Buyer FOB product purchases.
In addition to the [**] Reviews, Buyer, any two times during the Term of this
Agreement after [**], may, in accordance with the conditions of the immediately
preceding sentence, submit a Quoted Price to Seller [**] ("WILD CARD REVIEW").
Should the Quoted Price be lower than the Price, Seller will reduce its Price
for such Product(s) to Buyer for such Plant(s) or in such Conference(s) by [**]
or the difference in the Quoted Price and the applicable current Product price.
Any such Price adjustment shall take place [**] immediately following the date
on which Buyer submitted a Quoted Price. It is expressly understood that, should
Buyer submit a Quoted Price, the submission of such Quoted Price to Seller shall
be considered to be a [**] Review or a Wild Card Review, as the case may be,
regardless of whether the Quoted Price is for one or more Plants and/or one or
more Conferences.

         8.2      Adjustments greater than [**]. Notwithstanding the foregoing,
in the event that the Seller seeks to implement a calculated price increase per
Attachment E or Attachment F which is greater than [**] in any year for a
particular Plant or Plants, Buyer shall have the right to move those volumes to
an alternative supplier with 60 days notice and Buyer's obligations under
Section 2 shall be correspondingly reduced. Buyer will negotiate in good faith
to identify any equivalent potential volume from other Buyer cylinder filling
plants that may be moved to Seller's other production facilities, subject to the
competitiveness of the pricing at the Seller's alternative production sites and
subject to Buyer's contractual obligations to other suppliers. Increases to the
LOX and LIN prices at Kittery, Sacramento, Nashville and City of Industry will
be subject to a [**] cap for the increases permitted on [**]. Thereafter, they
will be subject to the [**] cap provided for herein. Seller may elect, at its
discretion, to implement only a [**] increase in a given year (or years) when
the escalation formula exceeds [**].

9.       [Reserved]

         10.1     Payment Terms. Seller shall invoice Buyer as each delivery of
Product is made or monthly if the parties so agree. All payments due Seller
hereunder shall be made to Seller at the location indicated on the invoice. The
undisputed portion of all invoices shall be payable net thirty (30) days. The
timely payment by Buyer of all amounts due and owing to Seller hereunder is an
express condition to the continued performance by Seller of its obligations
hereunder.

         10.2     Any sales tax imposed by any present or future law or by any
government authority in connection with any Product sold hereunder, if paid by
Seller as a result of its performance under this Agreement shall be added to
Seller's billing and paid by Buyer, unless Buyer provides Seller with an
applicable tax exemption certificate.

11.      Warranty.

         11.1     Seller's Sole Warranties. Seller warrants that each Product
shall conform to the specifications and express warranties set forth for such
Product in the Attachment(s) and that at the time of delivery, Seller shall have
good title and the right to transfer the same and that the same shall be
delivered free of encumbrances. THE FOREGOING WARRANTY IS THE SOLE WARRANTY AND
IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, IN FACT OR BY LAW,
INCLUDING, WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, ANY WARRANTY OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

12.      Indemnity.

         12.1     Each party shall be responsible for property damage and
personal injury arising from the negligent acts or omissions of such party. Each
party shall indemnify, defend and hold harmless the other party from all losses,
claims and/or damages arising from personal injury and/or tangible property
damage due to the negligent acts or omissions of such party. In the event a
party seeks to be indemnified hereunder, it shall promptly notify the other
party in writing of the facts and circumstances upon which any such claim
("CLAIM") is based. The other party shall defend each Claim with counsel of its
sole choice and shall have the sole authority to settle or compromise the same.
As long as the other party defends a Claim, the party shall not be responsible
for the fees of attorneys retained separately by the party bringing the Claim.
Upon the other party's request, the party bringing the Claim shall cooperate
with the other party in the defense of each Claim with such cooperation
including providing information necessary to

                                        9


answer interrogatories, producing requested documents and making employees
available as witnesses at oral deposition and/or trial. The parties intend that
the indemnity obligation provided for herein shall cover tangible property
damage, bodily injury and death, and each party hereby knowingly and
intentionally agrees to waive immunity from suit by the other party, which a
party may enjoy under any applicable workers' compensation law or any other
applicable federal, state or local law, rule or regulation to the extent
necessary to allow a party to be fully defended, indemnified and held harmless
hereunder. This paragraph shall survive termination of this Agreement for a
period of two (2) years. The foregoing obligations of a party shall not extend
to claims, losses or damages due to the acts or omissions of an indemnified
party and not be transferred to any third party without the prior written
consent of the indemnifying party.

13.      Limitation of Liability.

         13.1     Obligation to Warn. Buyer acknowledges that there are hazards
associated with the use of the Products, that it understands such hazards, and
that it is the responsibility of Buyer to warn its employees and others exposed
to such hazards through Buyer's storage and use of the Product. Seller shall
provide Buyer with copies of Material Safety Data Sheets relating to the
Products for Buyer to make such warnings, and Buyer shall hold harmless,
indemnify and defend Seller from and against any liability incurred by Seller
because such warnings were not made.

         13.2     Limitation on Claims. No claim of any kind with respect to
non-delivery of a Product shall be greater than the Price payable hereunder for
the Product in respect to which such claim is made and Buyer's sole and
exclusive remedy (except for the remedy of termination for material default in
accordance with the terms of Section 15.3 and the indemnification provisions set
forth in Section 12.1) for delivery of nonconforming Product to Buyer shall be
replacement by Seller of a like quantity of conforming Product at no additional
cost to Buyer plus the cost of cleaning all delivery vessels, storage vessels
and delivery equipment contaminated by such nonconforming Product. Buyer agrees
that the limitations set forth in this Section 13.2 and Section 13.3 shall
survive and apply even if any remedy herein is found to fail for its essential
purpose.

         13.3     Waiver of Consequentials. Seller shall not be liable in
contract or tort (including negligence and strict liability) for any direct
damages not expressly provided for in this Agreement or for any indirect,
special, incidental or consequential damages arising out of its performance or
non-performance hereunder. Buyer shall not be liable in contract or tort

                                       10


(including negligence and strict liability) for any indirect, special,
incidental or consequential damages arising out of its performance or
non-performance hereunder.

         13.4     All claims by Buyer having anything to do with any Product
sold or delivered by Seller (or not delivered) shall be made in writing within
sixty (60) days after delivery thereof (or after the same have been delivered),
and failure by Buyer to give such written notice shall constitute a complete
defense for Seller against all such claims.

14.      Force Majeure.

         14.1     Force Majeure Events. Neither party hereto shall be considered
in default in the performance of its obligations hereunder (other than its
obligation to make any payment of money hereunder), or be liable in damages or
otherwise for any failure or delay in performance that is due to strike,
lockout, concerted act of workers or other industrial disturbance, fire,
explosion, flood or other natural catastrophe, civil disturbance or acts of
terrorism, riot or armed conflict, whether declared or undeclared, curtailment,
shortage, rationing or allocation of normal sources of supply of labor,
materials, transportation, energy or utilities, accident, act of God, delay of
subcontractors or vendors, sufferance of or voluntary compliance with government
acts and government regulations (whether or not valid), embargo, machinery or
equipment breakdown, or any other cause, whether similar or dissimilar to any of
the causes or categories of causes described above, and that is beyond the
reasonable control of the party claiming excuse hereunder.

         14.2     Strikes, etc. Neither party hereto shall be required to make
any concession or grant any demand or request to bring to an end any strike or
other concerted act of workers.

         14.3     Notice. Either party affected by an event described in Section
14.1 shall, within forty-eight (48) hours after learning of such event and
ascertaining that it has affected or will affect its performance hereunder, give
notice to the other party, stating the nature of the event, its anticipated
duration and any action being taken to avoid or minimize its effect.

         14.4     Allocation of Products. If any event within Section 14.1 shall
only partially reduce Seller's ability to produce or deliver Product, Seller may
prorate its available supply among Buyer and Sellers other customers in a fair
and equitable manner. Notwithstanding the foregoing, in the event of a Seller
Force Majeure, the following priorities shall apply: (i) first priority will be
given to those customers where lack of supply may pose a public health and/or
safety risk (including the applicable customers of Buyer in this category); (ii)
second priority will

                                       11


be given pro rata to Buyer and Seller's other take or pay customers who are
affected by the Seller Force Majeure up to their total requirements; and (iii)
third priority will be given to Seller's other customers on such basis as seller
reasonably determines. This allocation applies not only to the curtailed
production at the Plants affected by the Force Majeure but also to Products held
in inventory in tanks at Seller's Plants. If during a Seller Force Majeure, the
Take or Pay Minimum is not satisfied, Seller shall waive the requirements of
Section 2.2 for so long as such Seller Force Majeure shall exist. Within 72
hours after the occurrence of any event within Section 14.1, Seller shall
provide Buyer with a written allocation plan.

         14.5     Other Supply Sources. If Seller, under the circumstances
described in this Article 14, is unable to supply the Reserved Volume of any
Product, Buyer may purchase such Product during the period of Seller's inability
from other qualified vendors and such purchases shall be deemed to have been
made from Seller for purposes of determining whether Buyer has purchased the
applicable Take-or-Pay Minimum.

15.      Financial Impairment; Breaches.

         15.1     Bankruptcy Scenarios. Unless otherwise required by law, if a
petition is brought by or against either party under any present or future
bankruptcy or insolvency laws seeking any reorganization, arrangement,
readjustment, liquidation, dissolution or similar relief with respect to such
party, or if either party shall make any assignment for the benefit of
creditors, or if a receiver is appointed for either party, the other party may,
at its option, terminate this Agreement by written notice. The election of any
option under this Section 16.1 shall not preclude the exercise of any other
option.

         15.2     Damages for Buyer's Breach. In the event of a material breach
of this Agreement by Buyer, which breach Buyer fails to cure within thirty (30)
days of written notice thereof from Seller (or, if such cure is not possible
within such thirty (30) days but has been commenced and is being diligently
pursued by Buyer, then such longer period as shall be necessary), Seller may
terminate this Agreement in addition to any other remedies it may have.

         15.3     Damages for Seller's Breach. In the event of a material breach
of this Agreement by Seller, which breach Seller fails to cure within thirty
(30) days of written notice thereof from Buyer (or, if such cure is not possible
within such thirty (30) days but has been commenced and is being diligently
pursued by Seller, then such longer period as shall be necessary), Buyer may
terminate this Agreement in addition to any other remedies it may have.

                                       12


16.      General Provisions.

         16.1     Representatives. Each party agrees to designate a
representative with decision-making authority for purposes of administering and
resolving disputes under this Agreement. Seller's initial representative shall
be Robert C. Brown and Buyer's initial representative shall be Pat Baker. Either
party may change its representative by written notice to the other party given
in accordance with Section 16.6.

terms and conditions of the Attachment(s) hereto constitutes the entire
agreement between the parties. No terms and conditions in any form of purchase
order, order acknowledgment or other acceptance forms issued with respect to
transactions under this Agreement shall alter the terms hereof and thereof and
objection is hereby made to all such additional or different terms. Acceptance
is expressly limited to the terms offered herein and therein. No modification or
waiver of this Agreement shall bind either party unless in writing and signed
and accepted by a duly authorized representative of each party. Headings of any

representative under Section 16.1 in an effort to obtain prompt resolution.
Neither party shall commence any action against the other until the expiration
of sixty (60) days from the date of referral to such senior managers; provided,
however, this shall not preclude a party from instituting an action seeking
injunctive relief to prevent irreparable damage to such party. In the event that
the senior managers are unable to resolve the dispute as set forth above, the
dispute shall be submitted to a mutually agreeable neutral advisor for initial
fact finding and non-binding mediation. Neither party shall unreasonably
withhold acceptance of such an advisor and the selection of the advisor shall be

fact finding and mediation. The advisor shall be instructed to complete fact
finding and the mediation within sixty (60) days of his or her appointment.

                         GASEOUS HELIUM SUPPLY AGREEMENT

         THIS GASEOUS HELIUM SUPPLY AGREEMENT (the "AGREEMENT"), made this July
30, 2004 (the "EFFECTIVE DATE") by and between Airgas, Inc., a Delaware
corporation having an office at 259 N. Radnor-Chester Road, Suite 100, Radnor,
Pennsylvania 19087 (hereinafter "AIRGAS") and The BOC Group, Inc., a Delaware
corporation, having an office at 575 Mountain Avenue, Murray Hill, New Jersey
07974 (hereinafter "BOC").

                                   WITNESSETH:

         WHEREAS, Airgas desires to purchase gaseous helium from BOC and BOC
desires to sell gaseous helium to Airgas.

         NOW THEREFORE, in consideration of the foregoing premise and the
following covenants, the parties hereto hereby agree as follows:

1.       DEFINITIONS. (a)(a) As used herein, the term "Product" shall mean bulk
gaseous helium delivered in jumbo tube trailers or gaseous helium delivered into
a tube trailer utilized as Airgas' helium storage vessel at helium transfill
facilities where BOC and Airgas facilities are co-located.

         (b)      As used herein, the term "SUPPLY PERIOD" shall mean the
fifteen (15) year period commencing on the Effective Date.

         (c)      As used herein, the term "CONTRACT YEAR" shall mean each
twelve (12) consecutive month period during the term hereof commencing with the
first day of the Supply Period.

         (d)      As used herein, the term "MMSCF" shall mean million standard
cubic feet, the term "CCF" shall mean hundred standard cubic feet and the term
"SCF" shall mean standard cubic feet.



         (e)      As used herein, the term "MAXIMUM VOLUME" shall mean [**],
which was the actual volume of gaseous helium, either in purified form or in a
mixture with other gases, supplied in high pressure cylinders to customers
located within the 48 contiguous states during the BOC fiscal year ending
September 30, 2003.

         (f)      The term "BOC'S US COCKTAIL MIX" shall mean [**]

2.       TERM. The term of this Agreement shall commence on the Effective Date
and shall continue until and shall expire upon the expiration of the Supply
Period. Notwithstanding the foregoing, Airgas shall have the right to terminate
the Agreement effective at the end of the tenth (10th) Contract Year, or
effective the end of any Contract Year thereafter, by giving BOC not less than
twelve (12) months prior written notice.

3.       BOC'S SUPPLY OBLIGATION. During the initial Contract Year, BOC shall be
obligated to supply all Product requested for delivery by Airgas, up to the
Maximum Volume. During subsequent Contract Years, BOC shall be obligated to
supply all Product requested for delivery by Airgas up to [**] of Airgas' actual
purchases of Product during the previous Contract Year, not to exceed the
Maximum Volume.

4.       Airgas' Purchase Obligation. (a) (a) On or before the 15th day of each
month during the Term, BOC shall provide Airgas with a written report showing
the amount of Product purchased by Airgas during the previous calendar month
(each a "Monthly Report" and collectively the "Monthly Reports") under this
Agreement. The parties shall use good faith efforts to promptly resolve any
disputes regarding the Monthly Reports and any disputes that cannot be amicably
resolved may be submitted by either party for Dispute Resolution as provided in
Section 16 hereof. Airgas shall be obligated to purchase, or pay for if not
purchased, [**] during the initial Contract Year and [**] of the difference
between BOC's supply obligation specified in Paragraph 3 and the amounts listed
on Exhibit I ("Take or Pay Quantity") during all subsequent Contract Years
hereunder. Airgas will use commercially reasonable efforts to purchase [**] of
its requirements for Product at facilities co-located with a BOC helium
transfill from BOC and such purchase will count towards the Take of Pay Quantity
to be purchased or paid for by Airgas. In the event that Airgas has failed to
purchase the Take or Pay Quantity during any Contract Year, Airgas shall be able
to avoid penalties for failing to purchase the Take or Pay Quantity by
purchasing a quantity of additional Product ("Shortfall Make-Up Volume") equal
to the shortfall during the previous Contract Year ("Shortfall Year") [**]. The
quantity of Shortfall Make-Up Volume taken by Airgas each month shall be
calculated by subtracting (i) [**] of Airgas' Take or Pay Quantity applicable to
the [**] from (ii) the total quantity of Product purchased by Airgas during such
month. In the event that Airgas fails to purchase sufficient Shortfall Make-Up
Volume to offset the shortfall relative to the Take or Pay Quantity during the
Shortfall Year, then in such event, Airgas shall pay to BOC, an amount equal to
(i) the shortfall versus the Take or Pay Quantity not satisfied during the [**],
multiplied by (ii) the applicable price for Product during the Shortfall Year
within thirty (30) days after the conclusion of the [**]. Shortfall Make-Up
Volume taken by Airgas during any [**] shall not be included in Airgas' volume
for purposes of determining whether Airgas has purchased the Take or Pay
Quantity during the [**].


                                        2




         (b)      To the extent consistent with its business needs, Airgas will
use all reasonable efforts to purchase Product at a reasonably constant monthly
rate.

         (c)      Contemporaneously with the execution hereof, BOC and Airgas
shall enter into a definitive written agreement that shall allocate Airgas'
volume purchases for Product under this Agreement and that certain Helium Supply
Agreement between BOC and Airgas dated September 1, 1996.

5.       DELIVERIES OF PRODUCT. (a) For Product delivered in tube trailers, BOC
shall deliver Product to facilities designated by Airgas in jumbo tube trailers
(nominal capacity of at least 170,000 scf) rented to Airgas by BOC. Tube
trailers provided by BOC may be switched out with Airgas-owned trailers. At
facilities where an Airgas cylinder filling facility is co-located with a BOC
helium transfill, Product shall be supplied via a pipeline connecting the BOC
helium transfill to the location in Airgas' plant where helium cylinders are
filled, with a tube trailer utilized as an intermediate storage vessel ("Storage
Trailer"), or via another mutually acceptable means. BOC will use commercially
reasonably efforts to deliver Product so as to avoid customer run-outs and use
commercially reasonable efforts to deliver Product within forty-eight hours of
receiving notice of a requested delivery.

         (b)      Deliveries which may be made during a strike or other labor
disturbance affecting Airgas shall be at the sole risk of Airgas. Airgas shall
indemnify and hold BOC harmless from and against all costs, damages, liabilities
or claims arising directly or indirectly from such deliveries.

         (c)      The volume of Product delivered in tube trailers shall be
measured by BOC when tube trailers are dispatched from BOC's facility. Billings
shall be made in cubic feet of gas at 70oF and at one atmosphere of pressure
using standard P.V.T. (pressure, volume, temperature) conversion tables. Airgas
may measure the volume of, and/or test, BOC's Product upon its arrival at the
Airgas facility to which it is being delivered and shall notify BOC within seven
(7)

                                        3


days of delivery if any Product is found to be less than the quantity
represented by BOC or is found to not meet specifications. In addition, Airgas
shall have a reasonable opportunity upon reasonable advance written notice to
test BOC's Product measuring devices at BOC's facilities during the Supply
Period. Airgas shall receive full credit for residual Product in tube trailers
returned to BOC with pressures of 500 p.s.i.g. or less. No credit shall be given
for residual Product in tube trailers returned to BOC with pressures in excess
of 500 p.s.i.g.

         (d)      The volume of Product delivered by BOC to Airgas via pipeline,
in accordance with Paragraph 5(a) above, shall be determined by measuring the
volume of Product filled into a Storage Trailer or stationary tubes by the
P.V.T. method described in sub-paragraph 5.(c) above.

         (e)      In the event that tube trailers returned from Airgas locations
for refilling (either BOC or Airgas tube trailers) require purging due to the
acts or omissions of Airgas, BOC shall so notify Airgas and Airgas shall have
forty-eight (48) hours in which to verify BOC's claim. Any, dispute that cannot
be amicably resolved may be submitted by either party for Dispute Resolution as
provided in Section 16 hereof. If tube trailers returned from Airgas locations
for refilling require purging due to the acts or omissions of Airgas, the
following charges shall apply:

[**]

6.       PRICE AND PRICE ADJUSTMENT. (a) The price for Product delivered
hereunder shall initially be [**] per ccf (the "BASE PRICe") FOB delivered to
the Airgas location, or for co-located facilities, delivered into the Storage
Trailer utilized as Airgas' helium storage vessel at the facility, subject to
adjustment pursuant to Sub-Paragraph 6(b).

         (b)      Effective [**], the price for Product shall be adjusted (up or
down) by [**] ("ADJUSTMENT Period").

         (c)      Notwithstanding the foregoing, in the event that BOC projects,
in good faith, that BOC's US Cocktail Mix cost will change by [**] during any
Adjustment Period, as compared to the previous Adjustment Period, BOC shall
adjust the price for Product hereunder by [**] of the projected price adjustment
for the next [**] effective the [**] prior to the next price adjustment date
(referred to hereinafter as a "[**] PRICE ADJUSTMENT"). In such case, the price
for Product effective the following [**] shall be calculated in the same manner
as if the [**] Price Adjustment had not taken place. No further adjustments
shall be made due to any inaccuracy of BOC's good faith projection of the change
in BOC's US Cocktail Mix cost as long as BOC's

                                        4


projection was accurate to within +/- 1%. However, in the event that BOC's
projection was inaccurate by more than 1%, the price for Product shall be
adjusted retroactive to the [**] effective date of the [**] Price Adjustment.
The adjusted price effective [**] shall be the price for Product effective prior
to the [**] Price Adjustment, plus [**] of the change in the price for Product
based on the actual change in BOC's US Cocktail Mix cost. A credit or additional
billing will be issued by BOC within thirty (30) days after completion of the
calculation of the value of BOC's US Cocktail Mix cost.

         (d)      Upon completion of the calculation of BOC's US Cocktail Mix
cost, BOC will provide to Airgas (i) the percentage of BOC's total supply
included in the calculation from each source, and (ii) the percentage change in
price for each of those sources from the previous Adjustment Period.

         (e)      Airgas shall have the right to audit BOC's calculation of
BOC's US Cocktail Mix cost after notifying BOC in writing of its intent to
conduct an audit which shall be completed within ninety (90) days of Airgas'
receipt of the result of BOC's calculation. Such audit will be conducted by a
mutually acceptable third-party auditor. The auditor shall only disclose to
Airgas whether BOC has completed the calculations in accordance with the
provisions of this Agreement, or in the event of an error in BOC's calculations,
the auditor shall inform both parties of the correct calculation. In the event
of a material error (greater than 1% error in price for Product), the price for
Product shall be adjusted retroactive to the relevant [**] price adjustment
date. For errors of less than 1%, no adjustments shall be made. Airgas shall
bear the cost of the audit unless a material error (greater than 1% error in
price for Product) is found, in which case the cost of the audit shall be borne
by BOC.

         (f)      Notwithstanding the foregoing, in the event that BOC seeks to
implement an annual price increase of greater than [**], Airgas shall have the
right to purchase Product from a lower cost supplier and reduce its Take or Pay
Quantity for that Contract Year and for subsequent Contract Years, by notifying
BOC within thirty (30) days of receipt of BOC's price increase notification. In
no event shall the Take or Pay Quantity hereunder be less than [**] per Contract
Year.

         (g)      In the event that Airgas, at its option, elects to purchase
Product that is guaranteed

                                        5


to conform to the specifications for either Analytical Grade 5 or Grade 5.5, the
price for Product shall [**]

7.       PRICE REOPENERS. (a) Either party shall have the right to request good
faith negotiations for the purpose of establishing new base prices to be
applicable during Contract Years [**], by providing written notice to the other
party not less than six (6) months prior to the end of the [**] Contract Years,
whichever is applicable. In addition, on not more than two occasions during the
term of this Agreement, but not before the end of the [**] Contract Year ("WILD
CARD REOPENER"), Airgas shall have the right to request a good faith
renegotiation of the price for Product if it believes that the market price is
below the then current price for Product hereunder by at least [**]. In the
event that the parties are not able to agree on new prices for Product within
ninety (90) days of the written notice requesting a price reopener, the price
for Product shall finally be determined via binding arbitration in accordance
with the procedure defined in subparagraph 7(b).

         (b)      If agreement on a new price for Product has not been reached
within ninety (90) days of the date of the requesting Party's notice requesting
redetermination, then the requesting Party may submit the resolution of this
matter to arbitration at any time within forty-five (45) days after the end of
such ninety (90) day period by giving the other Party written notice. Included
with such notice, such Party requesting arbitration shall name one (1)
arbitrator. The Party receiving such notice, shall, by notice to the other Party
within thirty (30) days thereafter, name the second arbitrator. Within ten (10)
days following designation of the second arbitrator, the two arbitrators so
selected shall name a third arbitrator and the three arbitrators so selected
shall resolve the dispute in the manner provided herein. If the two arbitrators
selected by the parties are unable to agree upon a third arbitrator, the third
arbitrator, upon application by either party, shall be selected by the American
Arbitration Association in Philadelphia, Pennsylvania in accordance with its
Commercial Arbitration Rules. The arbitrators selected to act hereunder shall be
qualified by education, experience, and training to decide upon the particular
question in dispute, and shall not be an employee or former employee of either
Party. The arbitrators shall be bound in their deliberations and decisions by
the parameters set forth in this Agreement. The arbitrators so appointed, after
giving the Parties due notice of hearing and reasonable opportunity

                                        6


to be heard, shall promptly hear and determine the question submitted and shall
render their decisions within one hundred twenty (120) days after the selection
or appointment of the third arbitrator. The decision of the arbitrators, or of a
majority thereof, made in writing, shall be final and binding upon the Parties
hereto as to the question submitted, and the Parties will abide by and comply
with such decisions. Each Party shall bear the expenses of its arbitrator, and
the expenses of the third arbitrator shall be borne equally by BOC and Airgas.
The sole issue to be decided by the arbitrators shall be the Price for Product
under this Agreement effective the beginning of the [**] Contract Years, as
applicable, for scheduled reopeners, or effective the date of Airgas' written
notice if for a Wild Card Reopener. Within ten (10) days following the selection
or appointment of the third arbitrator, Buyer and Seller shall simultaneously
submit to the arbitrators written proposals for a new Price for Product designed
to reflect the then current price at which willing buyers and sellers in
arms'-length transactions are currently agreeing to buy and sell Product under
long-term agreements, with greater weight given to other term sales by BOC and
to agreements most recently consummated. The arbitrators must select either
Buyer's or Seller's proposal. The arbitration shall be held in Pennsylvania. The
laws of the Commonwealth of Pennsylvania shall be applicable to all substantive
and procedural issues.

8.       TUBE TRAILER RENTAL; TUBE TRAILER SALE. (a) (a) At Airgas' request, BOC
shall provide jumbo tube trailers for the delivery of Product hereunder. If so
requested, such tube trailers shall be rented to Airgas for a monthly rate of
[**] per month. For partial months, daily rental shall be charged at the rate of
[**] per day. Rental will be assessed from the date on which a full trailer
departs the BOC filling facility until the date on which the empty trailer with
which the full trailer was switched out returns to BOC for filling.

         (b)      The tube trailer rental rates provided for in subparagraph
8(a) above will be reviewed at the end of the [**] years of this Agreement based
upon changes in appropriate indices.

         (c)      During the term, BOC agrees to provide jumbo tube trailers to
Airgas for storage of Product at the locations set forth on Exhibit II (the
"Option Trailers"). The Option Trailers (also specified by trailer no. in
Exhibit II) will be provided on a rent free basis provided, however, that until
Airgas asks that title to an Option Trailer be conveyed to it, Airgas will pay
BOC a monthly maintenance fee of [**] per Option Trailer. BOC shall have the
right to adjust the monthly

                                        7


maintenance fee at the end of the [**] years of this Agreement based on changes
in BOC's actual cost to maintain tube trailers.

         (d)      At any time and from time to time during the term, upon the
written request of Airgas, BOC shall convey title to one or more of the Option
Trailers to Airgas at a price of $1.00 per Option Trailer. Title to any Option
Trailers that have not previously been conveyed to Airgas prior to the end of
the term will be conveyed to Airgas at that time. Any Option Trailer conveyed to
Airgas hereunder shall be in good condition and shall be free and clear of any
liens or encumbrances.

         (e)      BOC shall execute such bills of sale and other instruments of
transfer as Airgas may reasonably request in connection with the transfer of
title to Option Trailers as provided herein.

9.       BILLING AND PAYMENT. BOC shall invoice Airgas for Product delivered
hereunder after each delivery. Invoices for tube trailer rental shall be issued
on a monthly basis. Payment shall be made to the address specified on BOC's
invoice net thirty (30) days. Any sales tax imposed by any present or future law
or by any government authority in connection with any Product sold or tube
trailer delivered hereunder, if paid, or to be paid, by BOC as a result of its
performance under this Agreement shall be added to BOC's billing and paid by
Airgas, unless Airgas provides BOC an applicable tax exemption certificate.

10.      SPECIFICATION AND WARRANTY. All Product delivered under this Agreement
shall be a minimum of conformance grade 5 purity which shall be defined as [**]
pure and shall meet the additional specifications set forth on Exhibit III,
unless Airgas, at its option, elects to purchase Product that meets the
specifications for either Analytical Grade 5 or Grade 5.5 Product (defined in
Exhibit III), in which case the Product shall meet such specifications. Any
quantity of Product shown by a recognized standard test to be of lesser purity
than the purity guaranteed by BOC may be rejected by Airgas, in its discretion,
but BOC reserves the right to confirm test results of all Product rejected.
THERE IS NO WARRANTY OF MERCHANTABILITY AND THERE ARE NO OTHER WARRANTIES,
EXPRESSED, OR IMPLIED, THAT EXTEND BEYOND THIS STANDARD OF PURITY.

11.      CLAIMS. All claims by Airgas having anything to do with any Product
sold or delivered by BOC (or not delivered) shall be made in writing within
sixty (60) days after delivery thereof (or after the same have been delivered),
and failure by Airgas to give such written notice shall

                                        8


constitute a waiver by Airgas of such claims and a complete defense for BOC
against all such claims.

12.      EXCUSED NON-PERFORMANCE. Either party's performance hereunder (except
the obligation to pay money when due) shall be subject to floods, strikes or
other labor disturbances, fires, accidents, wars, delays of carriers, inability
to obtain power or fuel, breakdown of major equipment, failure or loss of normal
sources of supply, restraints of government, or any other similar or dissimilar
cause beyond such party's reasonable control. Delivery of Product shall be made
by BOC from its facility normally serving Airgas hereunder. If sufficient
production from any such facility or any third party supplier to BOC becomes
unavailable for the reasons set forth immediately above, BOC may divide the
available production among its various contract customers; provided, however,
that the percentage decrease in the amount of Product delivered to Airgas shall
be no more than fifty percent (50%) of the percentage decrease in the amount of
Product delivered to such other customers generally (e.g., if deliveries to
other customers are reduce by 10%, deliveries to Airgas will be reduced by no
more than 5%). If the Take or Pay Quantity is not satisfied, Airgas shall be
given a waiver of the requirements of Paragraph 4 for as long as such BOC Force
Majeure shall exist. Within 48 hours after the occurrence of an event within
this Paragraph 12, BOC shall provide Airgas with a written allocation plan. BOC
shall use all reasonable efforts to obtain replacement Product from other
sources, either within or separate from BOC, on a temporary basis until
sufficient production is again available. Airgas shall be promptly notified of
the foregoing and shall have the right to decline any such temporary replacement
Product, but shall pay all additional costs incurred by BOC or Airgas associated
with any such Product that it accepts.

13.      ALLOCATIONS OF RESPONSIBILITY. (a) Final determination of the
suitability of Product for any use contemplated by Airgas is the sole
responsibility of Airgas, and BOC shall have no responsibility in connection
therewith. Airgas shall avail itself of testing devices to determine the purity
of the Product before Airgas uses such Product, as it sees fit, but no error in,
or failure to make, any such test shall impair any right on the part of Airgas
to obtain a refund or replacement as provided in Paragraph 13(d).

                                        9


         (b)      Neither party shall be liable to the other for consequential
damages under any circumstances, including without limitation, consequential
damages caused by or arising out of, in whole or in part, any negligent act or
omission or related strict liability.

         (c)      Subject to the provisions of Paragraph 12 and Paragraph 13(e)
herein, provided that BOC makes commercially reasonable good faith efforts to
perform its obligations hereunder, Airgas's sole and exclusive remedy for each
unexcused failure on the part of BOC to deliver Product to Airgas when required
hereunder, whether or not such failure was caused in whole or in part, by any
negligence, shall be to recover from BOC the difference between the cost to
Airgas of any purchase of Product in substitution for the Product BOC failed to
deliver and the lesser price that would have been applicable to the purchase of
such substituted quantity of Product hereunder. Any Product purchased from a
third-party pursuant to this paragraph shall be credited towards Airgas' Take Or
Pay Quantity for that Contract Year.

         (d)      Subject to the provisions of Paragraph 13(e) herein, provided
that BOC makes commercially reasonable good faith efforts to perform its
obligations hereunder, Airgas's sole and exclusive remedy for each unexcused
failure or act on the part of BOC whereby Product of a purity less than that
stated in Paragraph 10 hereof is delivered to Airgas, whether or not such
failure or act was, in whole or in part, negligent, or could be the basis of a
claim on the grounds of strict liability, shall be to receive a refund equal to
the price of such quantity of non-conforming Product, or the replacement thereof
with Product meeting the level of purity provided in Paragraph 10 at no
additional charge to Airgas.

         (e)      If at any time during the Supply Period, BOC shall fail on at
least three (3) separate occasions to provide Product as required under this
Agreement, unless excused pursuant to the provisions of Paragraph 12 above, and
each such failure shall continue for more than fifteen (15) days after notice
thereof from Airgas to BOC, Airgas may terminate this Agreement on sixty (60)
days written notice to BOC.

         (f)      It is a responsibility of Airgas to comply with all relevant
reporting obligations under the Emergency Planning and Community Right-to-know
Act of 1986 (SARA Title III) and any other statutes and regulations concerning
the storage, handling or use of Product or resulting from the presence of the
Product supplied under this Agreement. Further, it is the responsibility of
Airgas to warn and protect its employees and others exposed to the hazards posed
by Airgas's

                                       10


storage and use of Product. By execution of this Agreement, Airgas acknowledges
receipt of the Material Safety Data Sheet(s) which describe the Product. Upon
Airgas's request and BOC's approval, BOC will provide Haz-OP training for
Airgas's employees at BOC's standard charge therefor.

         (g)      Airgas acknowledges that it has (i) full knowledge of the
hazards associated with the storage, distribution and use of Product and Airgas
hereby assumes all responsibility for warning its personnel and any third
parties on its premises of such hazards and (ii) read and understands the
provisions of this Agreement, including the provisions of Paragraph 13 (a)-(e)
above.

14.      CONTRACTUAL. This Agreement shall not be binding upon BOC or Airgas
until it is executed and delivered by their duly authorized representatives. No
change, modification, discharge or waiver of or addition to any of said
provisions shall be binding upon BOC, or Airgas unless set forth in writing,
specifically identified as and executed and delivered by a duly authorized
representative of each of them, and no such change, modification, discharge or
waiver of or addition to any of said provisions shall be effected by any
acknowledgment or acceptance by BOC of any purchase order, acknowledgment or
other form submitted by Airgas specifying dates, quantities or locations and
also containing different or additional provisions. This Agreement shall inure
to the benefit of and shall be binding upon BOC and Airgas and their respective
permitted successors and assigns, including any entity (i) with which Airgas may
merge or consolidate or (ii) to which Airgas may transfer any of its
subsidiaries or assets comprising its distribution operations.

15.      GOVERNING LAW. The laws of the Commonwealth of Pennsylvania shall
govern the validity, effect, construction and interpretation of the terms of
this Agreement without application of the rules of law in Pennsylvania regarding
conflicts of laws.

16.      DISPUTE RESOLUTION. (a) Each party agrees to designate a representative
with decision-making authority for purposes of administering and resolving
disputes under this Agreement. BOC's initial representative shall be Philip
Kornbluth, and Airgas' initial representative shall be Pat Baker. Either party
may change its representative by written notice to the other party given in
accordance with Paragraph 17.

                                       11


         (b)      Unless a dispute resolution mechanism is expressly provided
for a particular dispute arising under this Agreement, any dispute between the
parties relating to this Agreement that cannot be resolved with reasonable
promptness shall be referred to each party's designated representative in an
effort to obtain prompt resolution. Neither party shall commence any action
against the other until the expiration of sixty (60) days from the date of
referral to such senior managers; provided, however, this shall not preclude a
party from instituting an action seeking injunctive relief to prevent
irreparable damage to such party. In the event that the senior managers are
unable to resolve the dispute as set forth above, the dispute shall be submitted
to a mutually agreeable neutral advisor for initial fact finding and non-binding
mediation. Neither party shall unreasonably withhold acceptance of such an
advisor and the selection of the advisor shall be made within thirty (30) days
after written notice by one of the parties for such fact finding and mediation.
The advisor shall be instructed to complete fact finding and the mediation
within sixty (60) days of his or her appointment.

17.      NOTICES. All notices or other communications required or permitted to
be given by one party to the other shall be in writing and shall be deemed given
when transmitted by confirmed facsimile, when delivered personally or by
overnight courier or three (3) business after being deposited in the United
States Postal Service. All such notices and communications shall be addressed
and delivered to the following addresses:

         (a)      If to Airgas, to Airgas, Inc., 259 N. Radnor-Chester Road,

Either party may change its address, facsimile number or receiving person by
providing written notice to the other party.

18.      ASSIGNMENT. Neither party shall assign this Agreement without the prior
written consent of the other party, provided that such consent shall not be
unreasonably withheld. Any purported

                                       12


assignment in violation of the provisions of the preceding sentence shall be
null and void and of no force and effect.

19.      ENFORCEABILITY. If any provision of this Agreement shall be determined
to be unenforceable or unlawful by a final judgment, not subject to appeal, of a
court of competent jurisdiction, the parties hereto shall nevertheless be bound
by the remaining provisions hereof; provided however, that either party hereto
shall have the right to have this Agreement reformed to preserve, so far as
possible, the economic bargain of the parties as expressed herein.

                           [SIGNATURE PAGE TO FOLLOW]
