                              STOCK PURCHASE AGREEMENT

              THIS STOCK PURCHASE AGREEMENT (this "Agreement") is entered 
into as of the 15th day of March, 1999, by and between MARK A. BAUMAN 
("Seller"), and NORTHCOAST ACQUISITION CORP., an Ohio corporation ("Buyer").

                                    WITNESSETH:

              WHEREAS, Seller owns all of the issued and outstanding shares 
of the capital stock (as more particularly in Section 3.2 hereof, the 
"Shares") of Northcoast of America Cryogenic Inc., an Ohio corporation (the 
"Company"); and

              WHEREAS, Seller desires to sell to Buyer, and Buyer desires to 
purchase from Seller, all of the Shares upon the terms and conditions 
hereinafter set forth;

              NOW, THEREFORE, Seller and Buyer hereby agree as follows:

                                     ARTICLE 1
                                          
                            PURCHASE AND SALE OF SHARES

       1.1    PURCHASE AND SALE.

              Subject to the terms and conditions of this Agreement, at the 
Closing (as defined in Section 6.1), Seller shall sell, transfer and deliver 
to Buyer, and Buyer will purchase from Seller, all of Seller's right, title 
and interest in and to all of the Shares.

       1.2    PURCHASE PRICE.

              The aggregate purchase price for all of the Shares (the 
"Purchase Price") shall be an amount equal to:

              (a)    Eight Hundred Eleven Thousand Dollars ($811,000.00), PLUS

              (b)    the Earn-Out Amount, if any, payable pursuant to Article 2
                     of this Agreement, MINUS

              (c)    the amount, if any, by which the Net Closing Indebtedness
                     (as defined below) exceeds $650,624.00, MINUS

              (d)    the amount, if any, by which $379,666.00 exceeds the
                     Closing Working Capital (as defined below); MINUS

                                       1


              (e)    the amount, if any, by which the Net Worth Differential (as
                     defined below) exceeds $45,000.00.

       1.3    CERTAIN DEFINITIONS.

              (a)    "Net Closing Indebtedness" means an amount equal to (i) 
the sum of all of the Company's indebtedness for borrowed money (including 
obligations in respect of principal, accrued interest, and any applicable 
prepayment charges or premiums), MINUS (ii) the sum of all cash and cash 
equivalents held by the Company (not including checks or drafts issued but 
not yet cleared), all as reflected on the Final Closing Balance Sheet (as 
defined below).  On the Closing Date, Seller will cause the Company to 
estimate in good faith the amount of the Net Closing Indebtedness in 
accordance with the preceding sentence, and will deliver to Buyer a 
certificate signed by Seller and the Company's chief financial officer 
setting forth such estimate (the "Debt Certificate"), together with such 
supporting detail and lender confirmations as Buyer may request.  The 
"Estimated Debt Adjustment" will be the amount, if any, by which the estimate 
of the Net Closing Indebtedness as set forth in the Debt Certificate exceeds 
$650,624.00.

              (b)    "Closing Working Capital" means the difference between 
(i) the Company's current assets MINUS (ii) the Company's current 
liabilities, all as reflected on the Final Closing Balance Sheet; PROVIDED, 
HOWEVER, that for purposes of such calculation, the Company's current assets 
will not include any accounts or notes receivable from NCI, Northcoast/Texas 
or Northcoast/Kansas, and the Company's current liabilities will not include 
any accounts or notes payable to NCI, Northcoast/Texas or Northcoast/Kansas 
and will not include any indebtedness for borrowed money (including 
obligations in respect of principal, accrued interest, and any applicable 
prepayment charges or premiums) taken into account in determining Net Closing 
Indebtedness.

              (c)    "Net Worth Differential" means the difference between 
(i) the net worth of the Company (I.E., all assets, net of depreciation and 
amortization, less all liabilities) as actually reflected on the Final 
Closing Balance Sheet, allowing for the variances from generally accepted 
accounting principles identified on Schedule 4.3.1(b) hereto, MINUS (ii) the 
net worth of the Company (I.E., all assets, net of depreciation and 
amortization, less all liabilities) as it would be reflected on the Final 
Closing Balance Sheet if the same were prepared without allowance for any of 
the variances from generally accepted accounting principles identified on 
Schedule 4.3.1(b) hereto.

       1.4    ESTIMATED PAYMENT AT CLOSING.

              At the Closing, Buyer will pay to Seller, subject to adjustment 
as provided in Section 1.5 and subject to Section 7.13, an amount (the 
"Closing Payment") equal to: (a) $811,000.00, MINUS (b) the Estimated Debt 
Adjustment, if any, pursuant to Section 1.3(a) hereof.  The Closing Payment 
will be paid by means of a wire-transfer of immediately available funds to an 
account designated by Seller.  If, and to the extent that, the portion of the 
Purchase Price payable before taking into account any Earn-Out Amount, as 
determined in 

                                       2


accordance with Sections 1.2(a), 1.2(c), 1.2(d), 1.2(e) and 1.5 hereof, is 
less than the Closing Payment, then Seller shall refund the amount of such 
difference to Buyer in accordance with Section 1.5 ("Post-Closing Purchase 
Price Adjustment").

       1.5    ADJUSTMENT.

              1.5.1  CLOSING BALANCE SHEET PREPARATION.

              Promptly after the Closing, Seller will prepare a balance sheet 
of the Company as of the Closing ("Preliminary Closing Balance Sheet").  The 
Preliminary Closing Balance Sheet will be prepared in accordance with 
generally accepted accounting principles and, to the extent permitted 
thereby, on a basis consistent with the past practices of the Company; 
PROVIDED, HOWEVER, that the preparation of the Closing Balance Sheet may vary 
from generally accepted accounting principles by not taking into account the 
accruals and adjustments identified as "GAAP Adjustments" on Schedule 
4.3.1(b) hereto.  Seller caused the Company to conduct a physical inventory 
as of March 7, 1999 (the "Pre-Closing Inventory"), the results of which shall 
be accurately reflected in the Preliminary Closing Balance Sheet.  Based on 
the Preliminary Closing Balance Sheet, Seller will prepare a written 
calculation of the Net Closing Indebtedness in accordance with the provisions 
of Section 1.3(a), a written calculation of the Closing Working Capital in 
accordance with the provisions of Section 1.3(b), and a written calculation 
of the Net Worth Differential in accordance with the provisions of Section 
1.3(c), and based thereon, a calculation of the Post-Closing Purchase Price 
Adjustment in accordance with the provisions of Section 1.4 (the "Preliminary 
Post-Closing Purchase Price Adjustment").

              1.5.2  CLOSING BALANCE SHEET REVIEW.

              Not later than forty-five (45) days after the Closing Date, 
Seller will deliver to Buyer the Preliminary Closing Balance Sheet and 
Seller's calculation of the Preliminary Post-Closing Purchase Price 
Adjustment.  All work papers, documents and records used or generated by 
Seller and his accountants and other representatives in connection with the 
preparation of its Preliminary Closing Balance Sheet and the calculation of 
the Preliminary Post-Closing Purchase Price Adjustment will be made available 
to Buyer.  Unless Buyer gives Seller a written objection by the thirtieth 
(30th) day after Buyer's receipt of the Preliminary Closing Balance Sheet and 
the Preliminary Post-Closing Purchase Price Adjustment, the Preliminary 
Closing Balance Sheet and the Preliminary Post-Closing Purchase Price 
Adjustment will become final and binding on the parties and shall be deemed 
to be the "Final Closing Balance Sheet" and the "Final Post-Closing Purchase 
Price Adjustment," respectively.

              1.5.3  CLOSING BALANCE SHEET DISPUTE.

              If Buyer objects to the Preliminary Closing Balance Sheet or to 
the Preliminary Post-Closing Purchase Price Adjustment and Buyer and Seller 
are able to resolve their dispute within fifteen (15) days after Buyer's 
objection, the Preliminary Closing Balance Sheet and the Preliminary 
Post-Closing Purchase Price Adjustment (each as adjusted to reflect such 

                                       3


resolution) will become final and binding on the parties and shall be deemed 
to be the "Final Closing Balance Sheet" and the "Final Post-Closing Purchase 
Price Adjustment," respectively.  If Buyer objects to the Preliminary Closing 
Balance Sheet or to the Preliminary Post-Closing Purchase Price Adjustment 
and Buyer and Seller are unable to resolve their dispute within fifteen (15) 
days after Buyer's objection, the dispute will be resolved in accordance with 
the terms of this Agreement by the firm of Arthur Andersen LLP (the 
"Independent Accountants").  The Independent Accountants will be instructed 
to perform their services as expeditiously as possible.  The resolution of 
the Independent Accountants shall be presented in a "Final Closing Balance 
Sheet" with respect to the Company and a "Final Post-Closing Purchase Price 
Adjustment" with respect to the Company, each prepared by the Independent 
Accountants, which shall be final and binding on the parties.

              The fees and expenses of the Independent Accountants for the 
resolution of any dispute shall be paid by Buyer and Seller in inverse 
proportion to the respective amounts of the disputed matters which are 
resolved in its favor.  For example, if:

                     (a)    Buyer claims that the Final Post-Closing Purchase
                            Price Adjustment should be $100;
       
                     (b)    Seller claims that the Final Post-Closing Purchase
                            Price Adjustment should be $20; and
              
                     (c)    the Independent Accountants determine that the Final
                            Post-Closing Purchase Price Adjustment is $40;

then the fees and expenses of the Independent Accountants would be paid 25% 
by Seller (I.E., 20 DIVIDED BY 80), and 75% (I.E., 60 DIVIDED BY 80) by Buyer.

              1.5.4  POST-CLOSING REFUND.

              If, after giving effect to the Final Post-Closing Purchase 
Price Adjustment, the portion of the Purchase Price payable before taking 
into account any Earn-Out Amount pursuant to Article 2, as determined in 
accordance with Sections 1.2(a), 1.2(c), 1.2(d), 1.2(e) and the foregoing 
provisions of this Section 1.5, is less than the Closing Payment, then Seller 
shall refund to Buyer the amount of such difference by means of a 
wire-transfer of immediately available funds to an account designated by 
Buyer.  Any such post-closing refund shall be made not more than three (3) 
days after the Preliminary Post-Closing Purchase Price Adjustment of the 
Company becomes the Final Post-Closing Purchase Price Adjustment of the 
Company.

                                      EARN-OUT

       2.1    EARN-OUT AMOUNT.

              Subject to the terms and conditions of this Agreement, Seller 
shall be entitled to receive, as a component of the Purchase Price for the 
Shares, an amount (the "Earn-Out Amount") equal to three percent (3%) of the 
Net Sales of the Northcoast Companies (each as defined below) with respect to 
each fiscal year or partial fiscal year during the three-year period that 
begins on the Closing Date ("Earnout Period"), subject to possible extension 
for one additional year in accordance with Section 2.3 hereof.

              2.1.1  NET SALES.

              (a)    As used herein, the term "Net Sales" shall mean (i) the 
Northcoast Companies' aggregated revenues in respect of sales and leases of 
goods or services by the Northcoast Companies, net of any returns, credits, 
discounts or allowances extended to customers and net of any freight charges, 
sales taxes and other similar charges, all as reflected on the books and 
records of the Northcoast Companies in accordance with generally accepted 
accounting principles, consistently applied, of Buyer, PLUS (ii) those 
revenues of Affiliates (as defined below) of the Northcoast Companies 
described in Section 2.1.1(b), MINUS (iii) those revenues of the Northcoast 
Companies described in Section 2.1.1(c).  Revenues described in the foregoing 
clause (i) shall include, without limitation, revenues in respect of:  repair 
and rehabilitation services with respect to cryogenic tanks, cryogenic 
trailers and liquid cylinders; installation, maintenance and replacement 
services with respect to VJ pipe; direct sales of pipe, pumps, trailers and 
tanks; and direct sales of leased cryogenic equipment.

              (b)    In the event any Affiliate of a Northcoast Company shall 
lease a product to an end-user customer of such Affiliate and, in connection 
with such lease transaction, a Northcoast Company shall enter into a contract 
with such Affiliate or with such customer to provide maintenance service with 
respect to the product so leased, then "Net Sales" shall include the revenues 
of such Affiliate in respect of such lease transaction, net of the items 
described in Section 2.1.1(a), as reasonably determined by Buyer.

              (c)    The parties acknowledge that, from time to time after 
the Closing, the Northcoast Companies may sell liquid cylinder repair 
services to customers who have previously purchased such services from, but 
whose business has been transferred or referred to the Northcoast Companies 
by, their Affiliates (collectively, "Transferred Liquid Cylinder Repair 
Business"). Section 2.1.1(a) notwithstanding, revenues realized by the 
Northcoast Companies in respect of Transferred Liquid Cylinder Repair 
Business shall be excluded from the calculation of "Net Sales" to the extent 
such revenues are likely to have been realized by such Affiliates, taking 
into account such customers' prior sales volumes, had such transfers or 
referrals not occurred.  The determination of the revenues to be excluded 
from the calculation of "Net Sales" pursuant to this Section 2.1.1(c) shall 
be made by mutual agreement of Buyer 

                                       5


and Seller, each acting reasonably and in good faith in accordance herewith, 
and set forth in a writing signed by such parties at the time at which each 
such transfer or referral occurs.

              (d)    For purposes of this Article 2, an "Affiliate" of a 
Northcoast Company means a corporation, partnership, limited liability 
company or other business entity which directly or indirectly controls, is 
controlled by, or is under common control with such Northcoast Company, and 
"control" means possession of the power to direct or cause the direction of 
the management and policies of an entity through ownership of voting 
securities or by contract.

              2.1.2  NORTHCOAST COMPANIES.

              As used herein, the term "Northcoast Companies" shall mean and 
include:

       (a)    Buyer, or, from and after any Business Combination (as defined
              below) involving Buyer, the business carried on using only the
              assets of Buyer (other than the Shares purchased hereunder) as
              such assets exist immediately after the consummation of the
              transactions contemplated by this Agreement, but including
              replacements thereof in the ordinary course of business, and taken
              substantially as an entirety, as reasonably determined by Buyer;
       
       (b)    the Company, or, from and after any Business Combination involving
              the Company, the business carried on using only the assets of the
              Company as such assets exist immediately after the consummation of
              the transactions contemplated by this Agreement, but including
              replacements thereof in the ordinary course of business, and taken
              substantially as an entirety, as reasonably determined by Buyer;
              and
       
       (c)    NCI Sales and Leasing, Inc., an Ohio corporation ("NCI"), or, from
              and after any Business Combination involving NCI, the business
              carried on using only the assets of NCI as such assets exist
              immediately after the consummation of the transactions
              contemplated by this Agreement, but including replacements thereof
              in the ordinary course of business, and taken substantially as an
              entirety, as reasonably determined by Buyer.

For purposes of this Section 2.1.2, a "Business Combination" shall mean a 
merger or consolidation to which a Northcoast Company is a constituent entity 
(whether or not it is the surviving entity), or a transaction in which a 
Northcoast Company transfers all or substantially all of its assets to 
another entity, or a transaction in which a Northcoast Company acquires all 
or substantially all of the assets of another entity.

       2.2    CALCULATION AND PAYMENT OF EARN-OUT AMOUNT.

              (a)    1999.  On or before March 1, 2000, Buyer will calculate 
and pay to Seller the Earn-Out Amount, if any, that accrues to Seller 
pursuant to Section 2.1 during the period from the Closing Date to December 
31, 1999.

              (b)    2000.  On or before March 1, 2001, Buyer will calculate 
and pay to Seller the Earn-Out Amount, if any, that accrues to Seller 
pursuant to Section 2.1 during the 12-month period that ends on December 31, 
2000.

              (c)    2001.  On or before March 1, 2002, Buyer will calculate 
and pay to Seller the Earn-Out Amount, if any, that accrues to Seller 
pursuant to Section 2.1 during the 12-month period that ends on December 31, 
2001.

              (d)    2002.  On or before May 1, 2002, Buyer will calculate 
and pay to Seller the Earn-Out Amount, if any, that accrues to Seller 
pursuant to Section 2.1 during the period that begins on January 1, 2002, and 
ends on the third anniversary of the Closing Date.

       2.3    SUPPLEMENTAL EARN-OUT OPPORTUNITY.

              If the sum of the amounts payable to Seller pursuant to 
paragraphs 2.2(a), 2.2(b), 2.2(c) and 2.2(d) (the "Three-Year Earn-Out") 
equals or exceeds One Million Dollars ($1,000,000.00), then no Earn-Out 
Amount shall accrue after the third anniversary of the Closing Date, and all 
further liability of Buyer under this Article 2 shall cease (except liability 
for payment of the Earn-Out Amount in accordance with Section 2.2).  If, and 
only if, the Three-Year Earn-Out is less than One Million Dollars 
($1,000,000.00), then Buyer, on or before May 1, 2003, will calculate the 
Earn-Out Amount, if any, that accrues to Seller pursuant to Section 2.1 
during the period that begins on the third anniversary of the Closing Date 
and ends on the fourth anniversary of the Closing Date (the "Fourth Year 
Earn-Out"), and will pay to Seller the LESSER of (a) the Fourth Year 
Earn-Out, or (b) such portion of the Fourth Year Earn-Out which, when added 
to the Three-Year Earn-Out, equals One Million Dollars ($1,000,000.00).  In 
other words, if the Three-Year Earn-Out is less than $1,000,000.00, then the 
sum of the Three-Year Earn-Out plus the Fourth Year Earn-Out shall not exceed 
$1,000,000.00.

Company, and, to the best knowledge of Seller and the Company, there are no 
such threatened claims, audits or proceedings.

pending to revoke or limit any of them or otherwise to impose any conditions 
or obligations on the possession or transfer of any of them.  In addition,

directives issued by any governmental authority with respect to the business 
of the Company or any of the Company's assets.  The Company is not required

made or threatened against the Company within the past three years.  There 
are no defects in the design or manufacture of products manufactured or sold 
by the Company which defects could result in a Product Liability Claim, and  
there has not been any failure by the Company to warn, test, inspect or 
instruct of dangers which could form the basis for a product recall or any 
Product Liability Claim against the Company.

              4.4.4  LITIGATION.

              Except as set forth on Schedule 4.4.4, no claim, litigation, 
investigation or proceeding is pending or, to the knowledge of Seller and the

on any Schedule to this Agreement, (i) the Company is not in default under or

or violation.  There have been no discussions or correspondence concerning 
the breach by the Company of, or the termination of, any of such Contracts.

service) has terminated, or threatened to terminate, its relationship with 
the Company or has during the past year decreased or delayed materially, or 
threatened to decrease or delay materially, its purchases from the Company or 
its sale of services or supplies to the Company, and there is no state of

transactions contemplated by this Agreement will not adversely affect the 
relationship of the Company with any customer or supplier.  The Company is 
not required, in the ordinary course of business, to provide any bonding or

plan which it maintains or to which it contributes.  The Company has the 
right to amend or terminate, without the consent of any other person or

              Except as set forth on Schedule 4.7.1, the Company owns, with 
good title, and in every case free and clear of all Liens, all of the

None of the Company's accounts receivable is subject to any set-off or 
counterclaim, and, to the knowledge of Seller and the Company, all of the 
Company's accounts receivable are collectible to the extent included on the 
Final Closing Balance Sheet.  Schedule 4.7.2 sets forth a 30/60/90 day aging 
summary of the Company's accounts receivable as of January 31, 1999.  Seller 
has delivered to Buyer the Company's complete aging schedule of accounts

                                       17

work-in-process, raw materials and supplies inventories can be used or 
consumed in the usual and ordinary course of business as now conducted and 
are not in amounts in excess of normal requirements.  The Pre-Closing 
Inventory was conducted in accordance with the Company's past practices and 
will be accurately reflected in the Preliminary Closing Balance Sheet.  The 
Company's actual inventories as of the Closing will be the same as reflected 
in the Pre-Closing Inventory except for sales or purchases of inventory in 
the ordinary course of business during the period from March 7, 1999, to the 
Closing.

there has not been any release of Hazardous Substances or Hazardous Waste at 
or from any properties adjacent to any current or former facilities of the 
Company.  To the knowledge of Seller and the Company, there are no materials 
containing asbestos or urea formaldehyde incorporated into the building or

assets leased by the Company, are in good operating condition, normal wear and
tear excepted, neither require nor

to remain in such condition beyond maintenance and repairs necessary in the

              4.7.6  LOCATION.

              All of the Company's assets are located at the address or

Schedule 4.7.7, the Company is not a party to any Contract, whether as

with respect to any Intellectual Property Rights. The Company has the right 
to use all Intellectual Property Rights as are necessary to enable the 
Company to conduct, and to continue to conduct after the Closing, all phases 
of its business in the manner presently conducted by the Company, and that 
use has not conflicted with, infringed upon or otherwise violated any rights 
of any person or entity.  The Intellectual Property Rights listed on Schedule 
4.7.7 are valid and in full force and effect and are not subject to any 
Taxes, maintenance fees, or actions falling due within the next three months. 
 Except as set forth on Schedule 4.7.7, there have been no interference 
actions or other judicial, arbitration or other adversary proceedings 
concerning the Intellectual Property Rights listed on Schedule 4.7.7.  The 
Company has not infringed any intellectual property right or other right of 
any other person or entity.  To the knowledge of Seller and the Company, none 
of the Intellectual Property Rights has been used, divulged or appropriated 
for the benefit of any past or present employees of the Company or any other 
person or entity, or to the detriment of the Company.  The Company has not 
disposed of or permitted to lapse, or otherwise failed to preserve the 
Company's right to use, any rights referenced in this Section 4.7.7.

              "Intellectual Property Rights" means and includes all

              4.7.8  EXTENT.

              The Company owns, or has a valid and subsisting interest as a 
lessee or licensee in, and in any case has the right to hold and to use, all 
assets (whether real, personal or mixed, and whether tangible or intangible) 
which have been used to conduct its business in the ordinary course as such 
business is presently being conducted.  Since the date of the most recent 
fiscal year-end balance sheet included on Schedule 4.3.1, there has not been 
any damage to or disposition (except for the sale of inventory in the 
ordinary course of business consistent with past practice) or loss of 
(whether or not covered by insurance) any asset of the Company.  Over the 
period covered by the financial statements included on Schedule 4.3.1, no 
aspect of the business of the Company was conducted by any affiliate of the 
Company or any affiliate of Seller or any former shareholder of the Company.

              Complete and accurate legal descriptions of all real property 
owned or leased by the Company are set forth on Schedule 4.8.  There is no 
state of facts or event which could reasonably be expected to form the basis 
for any condemnation proceedings which could effect such real property or any 
future improvements by any public authority, any part of the cost of which 
could be assessed against such real property.  In the past three years, the 
Company has not experienced any interruption in the delivery of adequate 
utilities required in the operation of its business.  The roof and foundation 
of the real property owned or leased by the Company are watertight and free 
of leaks, seepages and moisture.

no statement contained in any Schedule to this Agreement, contains any untrue 
statement of a material fact, or omits to state a material fact necessary to

                            required by any existing employee benefit plan;

                     (iv)   permit any of its assets to be subjected to any

                            course of business consistent with past practice, or
                            modify or terminate any Contract under circumstances
                            which might adversely affect the condition
                            (financial or otherwise) or prospects of the
                            Company's business;

                     (vi)   sell or dispose of any assets other than inventory

                            accounts receivable, or change its financial
                            structure; or

                     (viii) take any action the taking of which, or omit to take
                            any action the omission of which, would cause any of

                                       26


                            warranties herein to fail to be true and correct in 
                            all respects as of the date of such action or 
                            omission as though made at and as of the date of 
                            such action or omission, except as otherwise 
                            specifically contemplated by this Agreement.

              7.1.2  ACCESS.

              From the date hereof until the Closing, Seller will cause the 
Company to provide Buyer, its lenders and their representatives full access 
to the Company's personnel, facilities and all books and records and such 
other information and persons relating to the Company as Buyer may request.  
In addition, Seller will cause the Company to permit Buyer to perform 
engineering, environmental and workplace condition surveys and such other 
physical inspections as Buyer deems necessary.  If the transactions 
contemplated by this Agreement are not consummated for any reason, Buyer 
agrees to return to Seller all materials obtained from Seller or the Company 
and not to use for its own benefit any information not available to Buyer 
from a source other than Seller or the Company and not to disclose any 
information contained in the materials except information available to Buyer 
from a source other than Seller or the Company or required to be disclosed by 
law.

              7.1.3  INTERIM FINANCIAL STATEMENTS.

              Within 15 days after the end of each calendar month, if any, 
prior to the Closing, Seller will deliver to Buyer unaudited balance sheets 
of the Company and the related statements of income for the months then ended 
and for that portion of such fiscal year ended with the last day of such 
monthly accounting period, in each case certified by Seller to fairly present 
the financial position and results of operations of the Company as at or for 
the periods indicated on a basis consistent with past practice.

              7.1.4  SUPPLEMENTAL DISCLOSURE.

              Seller will immediately notify Buyer of any event or 
circumstance which makes it necessary to correct any representation and 
warranty contained in Article 3 or Article 4 which has been rendered 
inaccurate thereby; or arises hereafter and which, had it existed on or prior 
to the date hereof, would have resulted in an inaccuracy in a representation 
and warranty contained in Article 3 or Article 4.

              7.1.5  SATISFACTION OF CONDITIONS.

              Seller will, and will cause the Company to, use their 
respective best efforts to cause each of the conditions set forth in Section 
6.2 to Buyer's proceeding with the Closing to be satisfied at or before the 
Closing.  Buyer shall use its best efforts to cause each of the conditions 
set forth in Section 6.3 to Seller's proceeding with the Closing to be 
satisfied at or before the Closing.

                                       27


              7.1.6  TERMINATION.

              This Agreement may be terminated (i) by the written agreement 
of Buyer and Seller, or (ii) by Buyer or Seller at any time after March 23, 
1999, if the Closing shall not have taken place on or before such date.  If 
this Agreement is terminated pursuant to clause (i) of the preceding 
sentence, all provisions of this Agreement except Sections 7.3, 7.4 and 8 
shall become void without any liability on the part of any party.  If this 
Agreement is terminated pursuant to clause (ii) of the first sentence of this 
Section 7.1.6, all rights and remedies of each party hereunder and all other 
provisions hereof related thereto shall survive termination to the extent 
required so that any party responsible for any breach or nonperformance of 
its obligations hereunder prior to termination shall remain liable for the 
damages resulting therefrom.

       7.2    NONDISCLOSURE, NONCOMPETITION AND NONINTERFERENCE.

              Seller (i) shall at all times hold in strictest confidence any 
and all confidential data and other confidential information concerning the 
products, services, businesses, suppliers and customers of the Company, (ii) 
for a period of five (5) years following the Closing Date, shall not, without 
the prior written consent of Buyer, either directly or indirectly operate or 
perform any advisory or consulting services for, invest in (other than 
publicly traded stock constituting less than 5% of the equity of a publicly 
held corporation), or otherwise operate or become associated in any capacity 
with, any corporation, partnership, organization, proprietorship or other 
business entity or association which sells or performs services then in 
competition with the Company at any place within the United States of 
America, and (iii) for a period of five (5) years following the Closing Date, 
shall not, without the prior written consent of Buyer, directly or indirectly 
induce or attempt to induce any employee, agent or other representative or 
associate of the Company to terminate his or its relationship with the 
Company, or in any way knowingly interfere with such a relationship or a 
relationship between the Company and any of its suppliers or customers.  
Seller acknowledges that compliance with his covenants in this Section 7.2 is 
necessary to protect Buyer's and the Company's legitimate business interests 
and that any breach of any such covenant will result in irreparable and 
continuing damage to Buyer and the Company for which money damages alone will 
not provide an adequate remedy, and that in the event of any such breach or 
threatened breach of any such covenant, Buyer and the Company and their 
respective successors and assigns shall be entitled to injunctive relief, 
without having to post any bond, and to such other and further relief at law 
or in equity as is proper under the circumstances.

       7.3    PUBLICITY.

              Neither Buyer nor Seller will make any public announcement 
relating to this Agreement or the transactions contemplated hereby without 
the written consent of the other, unless and except to the extent otherwise 
required by law.  If public disclosure or notice is required by law, Buyer or 
Seller, as the case may be, will use his or its best efforts to give the 
other party prior written notice of the disclosure to be made.

                                       28


       7.4    EXPENSES; TRANSFER TAXES.

              Except to the extent otherwise specifically provided herein, 
Buyer shall pay all of the expenses incident to the transactions contemplated 
by this Agreement which are incurred by Buyer or its representatives, and 
Seller shall pay all of the expenses incident to the transactions 
contemplated by this Agreement which are incurred by the Company or by Seller 
or their respective representatives.  Seller shall pay all sales or other 
transfer Taxes, if any, which may be payable in connection with the 
transactions contemplated by this Agreement.

       7.5    {Intentionally omitted.}

       7.6    RECEIVABLES.

              Buyer shall cause the Company to use all reasonable efforts to 
collect the accounts receivable reflected on the Final Closing Balance Sheet 
but neither Buyer nor the Company shall be required to take or threaten legal 
action to collect any such accounts receivable. At the option of Buyer, 
Seller agrees to purchase from the Company, for an amount equal to the unpaid 
balance thereof, less any allowance for doubtful accounts reflected on the 
Final Closing Balance Sheet, all or any part of the accounts receivable 
included thereon which shall not have been paid within ninety (90) days after 
the Closing Date (other than accounts receivable from Northcoast/Texas, 
Northcoast/Kansas or NCI), it being understood that Buyer shall exercise such 
option at any time after such date up to the first anniversary of the Closing 
Date without waiving any rights hereunder.  Seller shall have the right to 
verify the existence of the unpaid balance of any accounts receivable.

       7.7    EMPLOYMENT.

              Seller shall pay the cost of any compensation, severance or 
other benefits which may be payable to any employees of the Company or to 
such other persons as shall claim compensation, severance or other benefits 
in connection with the consummation of the transactions contemplated by this 
Agreement. Subject to Sections 6.2(m) and 6.3(i), nothing in this Agreement 
shall be deemed to require the Company to retain after the Closing any of its 
employees for any period of time or at any particular compensation rate or in 
any particular position.

       7.8    {Intentionally omitted.}

       7.9    NO ASSIGNMENT.

              Without the consent of Seller, Buyer may assign all or any part 
of this Agreement and all or any part of its rights and obligations hereunder 
to any affiliate of Buyer, to any of Buyer's lenders, and to any person or 
entity which purchases from Buyer substantially all of Buyer's business, in 
which event Seller shall execute and deliver any documents reasonably 
requested by the assignee in connection with such assignment.  Except as 
provided in the preceding sentence, no assignment by any party of this 
Agreement or any 

                                       29


right or obligation hereunder may be made without the prior written consent 
of all other parties, and any assignment attempted without such consent will 
be void.

       7.10   CONSENT TO JURISDICTION.

              Any action or proceeding brought by a party against any other 
party in connection with this Agreement may be commenced in any federal or 
state court located in Cuyahoga County, Ohio, or Lucas County, Ohio, and all 
objections to personal jurisdiction and venue in any action or proceeding so 
commenced are hereby waived.  So long as service and process is by notice as 
provided in Section 9.1 of this Agreement or as required by any such court, 
all objections to improper service of process are hereby waived.  

       7.11   FURTHER ASSURANCES AND ASSISTANCE.

              The parties agree that each will execute and deliver any and 
all documents in addition to those expressly provided for herein that may be 
necessary or appropriate to effect or give evidence to the provisions of this 
Agreement and each of the other agreements and instruments delivered by them 
in connection herewith and the consummation of the transactions contemplated 
hereby.  Seller further agrees that at any time and from time to time after 
the Closing, it will execute and deliver to Buyer such further conveyances, 
assignments or other written assurances as Buyer may reasonably request to 
perfect and protect Buyer's title to the Shares.

       7.12   RIGHT OF SET-OFF.

              Upon notice to Seller, Buyer may set-off against any payments 
of Earn-Out Amount payable pursuant to Article 2 of this Agreement (i) any 
amounts to which Buyer may be entitled under Article 8 hereof, (ii) any 
amounts to which Buyer may be entitled under Article 8 of the Asset Purchase 
Agreement, (iii) any amounts to which Chart or NCI Acquisition may be 
entitled under Article 8 of the NCI Merger Agreement, (iv) any amounts to 
which Chart or its nominee may be entitled under Article 10 of the Michigan 
Option Agreement, the Georgia Option Agreement or the Texas Option Agreement. 
The exercise of such right of set-off by Buyer in good faith, whether or not 
ultimately determined to be justified, will not constitute a breach of this 
Agreement.  Neither the exercise of nor any failure to exercise such right of 
set-off will constitute an election of remedies or limit Buyer, NCI 
Acquisition, or Chart or its nominees in any manner in the enforcement of any 
other rights or remedies that may be available to any of them.

       7.13   CERTAIN TAX MATTERS.

              After the Closing, Buyer, the Company and Seller will 
coordinate the preparation of all necessary Tax Returns relating to the 
Company with respect to periods ending on or before the Closing Date.  Each 
party agrees to timely furnish to the other party any records and other 
information reasonably requested by it in connection therewith. 
Notwithstanding any other provision of this Agreement or any disclosure to 
Buyer hereunder or otherwise, Seller shall be responsible for the payment of, 
and shall pay, any and all federal, 

                                       30


state and local income taxes (including interest and penalties, if any) 
payable by the Company with respect to all periods ending on or before the 
Closing Date (collectively, "Pre-Closing Taxes"), and will promptly reimburse 
Buyer or the Company upon demand for any payments of Pre-Closing Taxes which 
either Buyer or the Company or any of their Affiliates may make after the 
Closing.  To secure such obligation, but without limiting Buyer's rights or 
Seller's obligations under the preceding sentence, Seller will deposit with 
Buyer at the Closing, or Buyer may withhold from the portion of the Purchase 
Price payable to Seller at the Closing pursuant to Section 1.4 hereof, cash 
in the amount of Twenty-Five Thousand Dollars ($25,000.00) (the "Estimated 
1998 Tax Payment").  Buyer shall apply the Estimated 1998 Tax Payment to the 
payment of all Pre-Closing Taxes and, no later than the date which is six (6) 
months after the Closing Date, shall pay to Seller the remainder, if any, of 
the Estimated 1998 Tax Payment not so applied.

                                  INDEMNIFICATION

       8.1    INDEMNIFICATION BY SELLER.

              Seller shall indemnify Buyer and the Company against and hold 
Buyer and the Company harmless from (i) any and all loss, damage, liability 
or deficiency (collectively, "Losses") resulting from or arising out of any 
inaccuracy in or breach of any representation, warranty, covenant or 
obligation made or incurred by Seller herein or in any other agreement, 
instrument or document delivered by or on behalf of Seller in connection 
herewith; and (ii) any and all costs and expenses (including reasonable legal 
and accounting fees) (collectively, "Expenses") related to any of the 
foregoing.  In addition, and notwithstanding any disclosure to Buyer 
hereunder or otherwise, Seller shall indemnify Buyer and the Company and 
their respective Affiliates against and hold them harmless from any and all 
Losses resulting from or arising out of:  (i) the death of the Company's 
employee Hillard Mitchell Jr. in or about September 1998, and any and all 
Expenses related thereto, including in any present or future litigation 
relating thereto; and (ii) any matters alleged by plaintiffs in the pending 
litigation captioned ANDREW WILBORN AND DEMETRIUS WILBORN VS. NORTHCOAST OF 
TEXAS CRYOGENIC, INC. [sic], Case No. 98-42541 in the 151st Judicial 
District, Harris County, Texas, or in the pending litigation captioned ANDREW 
WILBORN AND DEMETRIUS WILBORN V. NORTHCOAST CRYOGENIC, INC. [sic], Case No. 
2:98-CV-296 PG in the United States District Court for the Southern District

including in any other present or future litigation relating to such matters.

       8.2    INDEMNIFICATION BY BUYER.

              Buyer shall indemnify Seller against and hold Seller harmless 
from (i) any and all Losses resulting from or arising out of any inaccuracy 
in or breach of any representation, warranty, covenant or obligation made or 
incurred by Buyer herein or in any other agreement, instrument or document 
delivered by or on behalf of Buyer in connection herewith; and (ii) any and 
all Expenses related to any of the foregoing.

       8.3    NOTIFICATION OF AND PARTICIPATION IN CLAIMS.

              No claim for indemnification will arise until notice thereof is 
given to the party from whom indemnity is sought.  In the event that any 
legal proceedings shall be instituted or any claim or demand be asserted by 
any third party in respect of which Seller on the one hand, or Buyer on the 
other hand, may have an obligation to indemnify the other, the party 
asserting such right to indemnity shall give or cause to be given to the 
party from whom indemnity may be sought written notice thereof, and such 
party shall have the right, at its option and expense, to be present at the 
defense of such proceeding, claim or demand, but not to control the 

                                       32


defense, negotiation or settlement thereof, which control shall at all times 
rest with the party asserting such right to indemnity, unless the party from 
whom indemnity may be sought irrevocably acknowledges full and complete 
responsibility for indemnification of the party asserting such right to 
indemnity, in which case such party may assume such control through counsel 
of its choice.  The parties agree to cooperate fully with each other in 
connection with the defense, negotiation or settlement of any such third 
party legal proceeding, claim or demand.

       8.4    SURVIVAL; LIMITATIONS ON INDEMNIFICATION.

              The representations, warranties, covenants and agreements of 
the parties contained herein or in any other agreements or documents executed 
in connection herewith shall survive the Closing.  Notwithstanding the 
foregoing, the indemnification of Buyer and the Company provided under 
Section 8.1 shall be limited in certain respects as follows:  any claim for 
indemnification relating to any inaccuracy in or breach of any representation 
or warranty of Seller must be made within eighteen (18) months after the 
Closing Date, except that (i) there shall be no limits on the time for making 
a claim for indemnification relating to the representations and warranties 
contained in Article 3 ("Seller's Representations and Warranties Concerning 
the Transaction"), Sections 4.1.1 ("Organization and Power"), or 4.7.1 
("Title"), (ii) any claim for indemnification relating to the representations 
and warranties contained in Section 4.3.4 ("Taxes") may be made until the 
expiration of the applicable statute of limitations for either the assessment 
or collection of Taxes for the periods referred to therein, and (iii) any 
claim for indemnification relating to the representations and warranties 
contained in Sections 4.6 ("Employee Benefits") or 4.7.4 ("Environmental 
Matters") may be made until the second (2nd) anniversary of the Closing Date. 
There shall be no limits on the time for making a claim for indemnification 
relating to the undertakings of Seller set forth in Section 7.13 hereof or in

waiver shall constitute a waiver of any other provision hereof (whether or 
not similar), or a continuing waiver.
