     This Amendment No. 9 amends and supplements the Solicitation/Recommendation
Statement on Schedule 14D-9 filed with the Securities and Exchange Commission
(the "Commission") on November 16, 1995, and as subsequently amended (as so
amended, the "Schedule 14D-9"), by CBI Industries, Inc., a Delaware corporation
(the "Company" or "CBI"), relating to the tender offer made by PX Acquisition
Corp. ("P Sub"), a Delaware corporation and a wholly owned subsidiary of
Praxair, Inc., a Delaware corporation ("Praxair"), to purchase all outstanding
shares of Common Stock, including the associated Rights issued pursuant to the
Amendment and Restatement dated as of August 8, 1989 of a Rights Agreement dated
as of March 4, 1986, between the Company and First Chicago Trust Company of New
York, as Rights Agent, at a price of $33.00 per Share, net to the seller in
cash, upon the terms and subject to the conditions set forth in the Offer to
Purchase dated November 3, 1995, as amended and supplemented by the Supplement
to the Offer to Purchase dated December 28, 1995 and the related revised Letter
of Transmittal (which together constitute the "Amended Praxair Offer"). Unless
otherwise indicated, all capitalized terms used but not defined herein shall
have the meanings ascribed to them in the Schedule 14D-9.
 
ITEM 2. TENDER OFFER OF THE BIDDER.
 
     The description under Item 2 is hereby amended and supplemented by adding
the following information:
 
     This Statement relates to the tender offer by P Sub to purchase all
outstanding Shares at a price of $33.00 per Share, net to the seller in cash,
without interest thereon, on the terms and subject to the conditions set forth
in the Amended Praxair Offer.
 
     The Amended Praxair Offer is being made pursuant to an Agreement and Plan
of Merger, dated as of December 22, 1995, among Praxair, P Sub and the Company
(the "Merger Agreement"). The Merger Agreement provides that following
consummation of the Amended Praxair Offer, subject to the other conditions
contained in the Merger Agreement, including, if required by law, obtaining the
necessary vote of the Company's stockholders in favor of the Merger Agreement
and the merger of P Sub with and into the Company, P Sub will be merged with and
into the Company (the "Merger") and each outstanding Share (other than Shares
owned by Praxair, P Sub or their subsidiaries, and other than any Shares held by
stockholders who perfect their dissenters' rights under Delaware law) will be
converted into the right to receive $33.00 in cash. The Merger Agreement also
provides for the payment of a $43.5 million fee to Praxair under certain
circumstances if the Merger Agreement is terminated. A summary of the Merger
Agreement is contained in Section 7 of the Supplement to the Offer to Purchase
dated December 28, 1995, which is filed as Exhibit 28 to Praxair's Schedule
14D-1; a copy of which is enclosed with this Schedule 14D-9, and such summary is
incorporated herein by reference. Such summary should be read in its entirety
for a more complete description of the terms and provisions of the Merger
Agreement. The foregoing description of certain terms of the Merger Agreement
and the summary referred to above are qualified by reference to such Exhibit and
to the Merger Agreement, which is attached as Exhibit 37 to the Schedule 14D-9
and is incorporated herein by reference.
 
     Pursuant to the Merger Agreement, the CBI Restricted Stock Award Plan
(1978), the CBI 1983 Restricted Stock Award Plan, the CBI 1989 Restricted Stock
Award Plan and the CBI 1994 Restricted Stock Award Plan (the "Restricted Stock
Plans") will terminate following the purchase of Shares pursuant to the Amended
Praxair Offer. Under the terms of the Restricted Stock Plans, all restrictions
on Shares granted under such plans will lapse following a termination of such
plans after a Change in Control (as defined). The acquisition by Praxair of
beneficial ownership of 10% or more of the Shares will constitute a Change in
Control for purposes of the Restricted Stock Plans.
 
     The Compensation Committee of the Board has approved certain awards under
the CBI 1994 Restricted Stock Award Plan (the "1994 Restricted Stock Plan")
effective immediately prior to the termination of the 1994 Restricted Stock
Plan. Specifically, the Committee resolved that 94.1% of each award based on
1995 performance will be deemed earned and will be paid in cash upon termination
of the 1994 Restricted Stock Plan, and all awards based on performance for
fiscal years 1996 and 1997 will be awarded as if payable in full and will be
paid in cash.

ITEM 3. IDENTITY AND BACKGROUND.
 
     The description under Item 3 is hereby amended and supplemented by adding
the following information:
 
     On December 19, 1995, Praxair announced that it had made a proposal to the
Company to increase the price per Share to be paid in the Praxair Offer from
$32.00 to $33.00. Praxair said that if the Company's Board of Directors did not
accept its proposal and sign a merger agreement by 5:00 p.m. Eastern time on
December 21, 1995, it would withdraw the offer and continue with the $32.00 per
Share Praxair Offer. On December 21 and 22, 1995, the Board met to discuss the
Amended Praxair Offer and related matters. On December 22, 1995, the Board
determined that the Amended Praxair Offer and the Merger are fair to and in the
best interests of the Company and its stockholders. On December 22, 1995, the
Merger Agreement was executed by the parties thereto and Praxair and the Company
issued a press release announcing the execution of the Merger Agreement. See
also Item 2 above.
 
ITEM 4. THE SOLICITATION OR RECOMMENDATION.
 
     The description under Item 4 is hereby amended and supplemented by adding
the following information:
 
     At a meeting of the Board on December 22, 1995, the Board determined that
the Amended Praxair Offer and the Merger are fair to and in the best interests
of the Company and its stockholders. THE BOARD RECOMMENDS THAT THE COMPANY'S
STOCKHOLDERS ACCEPT THE AMENDED PRAXAIR OFFER AND TENDER THEIR SHARES PURSUANT
TO THE AMENDED PRAXAIR OFFER.
 
     In reaching its conclusions with respect to the Amended Praxair Offer, the
Board considered a number of factors, including the following:
 
     (1) The terms and conditions of the Amended Praxair Offer and the Merger
Agreement, including the price to be paid in the Amended Praxair Offer and the
Merger;
 
     (2) The written opinions of Lehman Brothers Inc. and Merrill Lynch & Co.
that, as of the date of such opinions, the $33.00 per Share to be offered to the
stockholders of the Company pursuant to the Amended Praxair Offer and the Merger
is fair to such stockholders from a financial point of view (copies of such
opinions setting forth the assumptions made and matters considered and
limitations set forth by Lehman Brothers Inc. and Merrill Lynch & Co. are
included as Annexes A and B hereto, respectively, and stockholders are urged to
read such opinions in their entirety);
 
     (3) The recommendation of management of the Company that the Amended
Praxair Offer and the Merger be approved;
 
     (4) The directors' knowledge of the Company's business, financial
condition, results of operations, current business strategy and future
prospects, the nature of the markets in which the Company operates, the
Company's position in such markets, and the efforts by the Company's management,
with the advice and assistance of its legal and financial advisors, to explore
other possible transactions involving the Company; and
 
     (5) the historical and current market prices for the Shares.
 
     The Board also considered communications from a third party indicating an
interest in discussing an acquisition of the Company's industrial gas business
for $2.05 billion, which amount would include the assumption of debt. Such party
indicated it was interested only in pursuing an acquisition of such business and
not an acquisition of any of the Company's other businesses or the Company as a
whole. The Board considered the responses to its search for potential buyers of
the Company's non-gas businesses and the possibility of distributing such
businesses to the Company's stockholders by means of a dividend, including the
views of its financial advisors with respect to the range of potential market
values of such businesses. The Board determined to recommend the Amended Praxair
Offer after taking into account the foregoing, the fact that there was no
assurance that a definitive agreement with such third party for the disposition
of the industrial gas business could have been negotiated, as well as the
uncertainties, costs and delays associated with a disposition of the Company's
businesses in separate transactions, including the uncertainty related to the
value at which the securities of the non-gas businesses would trade following
the public distribution thereof.

     The foregoing discussion of the information and factors considered and
given weight by the Board is not intended to be exhaustive. In view of the
variety of factors considered in connection with its evaluation of the Amended
Praxair Offer, the Board did not find it practicable to, and did not, quantify
or otherwise assign relative weights to the specific factors considered in
reaching its determination. In addition, individual members of the Board may
have given different weights to different factors.
 
     At the December 22, 1995, meeting of the Board, the Board also approved the
Amended Praxair Offer and the Merger for the purposes of eliminating the
application of Section 203 of the DGCL, and also approved the Amended Praxair
Offer and the Merger for purposes of Article Tenth and Article Fifteenth of the
Certificate. The Board also took certain actions with respect to the Rights as
described below under Item 8.
 
     A copy of the letter to the Company's stockholders communicating the
Board's recommendation is filed as Exhibit 38 to the Schedule 14D-9 and is
incorporated herein by reference.
 
ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.
 
     The description under Item 6 is hereby amended and supplemented by adding
the following information:
 
     To the best of the Company's knowledge, except to the extent such action
could subject them to liability pursuant to the federal securities laws or
except to the extent restricted by the terms of the plans under which such
Shares were issued, all of its executive officers, directors or affiliates
currently intend to tender any Shares which are held of record or beneficially
owned by such persons pursuant to the Amended Praxair Offer.
 
ITEM 7. CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY.
 
     The description under Item 7 is hereby amended and supplemented by adding
the following information:
 
     On December 22, 1995, the Company entered into the Merger Agreement with
Praxair and P Sub. Reference is made to the information set forth under Items 2
and 3 above.
 
ITEM 8. ADDITIONAL INFORMATION TO BE FURNISHED.
 
     The description under Item 8 is hereby amended and supplemented by adding
the following information:
 
     Litigation. Pursuant to the Merger Agreement, the Company, Praxair and P
Sub agreed to dismiss immediately, with each party bearing its own costs and
litigation expenses, all proceedings pending between themselves and their
affiliates and to sign and deliver such further papers as may be necessary in
connection with such dismissals.
 
     The Rights Agreement. At its meeting on December 22, 1995, the Company's
Board of Directors authorized an amendment to the Rights Agreement, (the "Rights
Plan Amendment") to amend the definition of "Permitted Tender Offer" such that a
"Permitted Tender Offer" is any offer which the Board, in its sole discretion
and subject to any conditions the Board deems proper, determines to be a
Permitted Tender Offer. The Board further determined that, so long as the Merger
Agreement has not been terminated, the Amended Praxair Offer is a Permitted
Tender Offer, no "Distribution Date" (as defined in the Rights Agreement) will
occur and Section 11.1(b) of the Rights Agreement will not be triggered, in each
case as a result of the announcement, commencement or consummation of the
Amended Praxair Offer or the execution and delivery of the Merger Agreement,
with the effect that none of such events will trigger the exercisability of the
Rights or the separation of the Rights from the certificates to which they are
attached.
 
     Information Statement. The Information Statement attached as Schedule I
hereto is being furnished in connection with the possible designation by
Praxair, pursuant to the Merger Agreement, of certain persons to be appointed to
the Board other than at a meeting of the Company's stockholders.

     The Company Common Stock and the Company's Convertible Voting Preferred
Stock, Series C (the "Series C Preferred Stock") vote together as a class. Each
share of Common Stock entitles the record holder thereof to one vote on each

by a resolution of the Board, divided into three classes, with members of each

                               BOARD OF DIRECTORS
 
RIGHT TO DESIGNATE DIRECTORS;  THE PRAXAIR DESIGNEES
 
     The Merger Agreement provides that promptly upon the purchase of and
payment for any shares by Purchaser pursuant to the Amended Praxair Offer which
represent at least a majority of the Shares (on a fully diluted basis) and from
time to time thereafter, Praxair and P Sub shall be entitled to designate
members of the Board such that Praxair and P Sub, subject to compliance with
Section 14(f) of the Exchange Act, will have a number of representatives on the
Board, rounded up to the next whole number equal to the product of (x) the total
number of directors on the Board multiplied by (y) the percentage of the
outstanding Shares beneficially owned by P Sub or its affiliates; provided,
that, any action to be taken prior to the Effective Time (as defined in Section
2.3 of the Merger Agreement) by the Board shall be approved by a majority of
those directors of the Company who have not been designated by Praxair or P Sub.
Notwithstanding the foregoing, until the Effective Time, the Merger Agreement
provides that the Company and Praxair shall use all reasonable efforts to retain
as members of the Board at least two directors who at the time are neither
officers of Praxair or the Company (or any of their respective affiliates), nor
designees of P Sub (or any of its affiliates), nor shareholders or affiliates of
P Sub (or any respective affiliate) (the "Disinterested Directors"). The Merger
Agreement also requires the Company to, upon request by Praxair or Purchaser,
promptly increase the size of the Board to the extent permitted by the Company's
Certificate and, to the extent required to comply with Section 1.3 of the Merger
Agreement, secure the resignations of such number of directors as is necessary
to enable Praxair's designees to be elected to the Board and shall cause
Praxair's designees to be so elected.
 
     The Company has been advised that the Praxair Designees will be selected by
Praxair from among the individuals listed below. The Company has been advised
that each of the Praxair Designees has consented to serve as a director of the
Company if appointed or elected and that none of the Praxair Designees owns any
Shares. In addition, none of the Praxair Designees is a director of, or holds
any position with, the Company. The name, age, present principal occupation or

SECTION 16(A) REPORTING DELINQUENCIES
 
     Under rules adopted by the Securities and Exchange Commission effective May
1, 1991, the Company is required to report certain information about any
director, officer, beneficial owner of more than ten percent of its Common Stock
or its Preferred Stock, or any other person subject to Section 16 of the
Securities Exchange Act of 1934 that failed to file on a timely basis the
reports required by Section 16(a) of the Exchange Act (the "Reports") during the
last fiscal year. Based upon information furnished to the Company, including the
Reports in question, as contemplated by the rules, it appears that Mr. MacDougal
filed one Form 4 late with regard to one sale transaction and that two officers,
Mr. Duffy, Vice President-Human Resources, and Mr. Schneider, then Vice
President and Controller, each filed one Form 5 late with regard to reporting
transactions under the Company's Dividend Reinvestment Plan.

(1) The amounts were earned in the stated year and paid in the following year
    pursuant to annual incentive bonus opportunities described under the caption
    "Compensation Committee Report on Compensation Awards."
 
(2) Amounts earned in 1994 (but awarded in 1995) were pursuant to the CBI 1994
    Restricted Stock Award Plan (see description under the caption "Long Term
    Incentive Plans" and "Compensation Committee Report on Compensation Awards")
    and reflects restricted stock earned pursuant to 50% of the target awards
    granted in 1994 for which performance is measured at the end of 1994.
    Restrictions on these shares expire January 1, 1999. Amounts awarded in 1993
    were pursuant to the CBI 1989 Restricted Stock Award Plan.
 
(3) Restricted Stock Awards are valued at the closing price on the date of
    grant. Participants receive dividends on the Restricted Stock reported in
    this column. The number and value of the aggregate restricted stock holdings

(4) It is the present policy of the Compensation Committee not to award SARs
    either at the time of grant or during the term of the option.
 
(5) The compensation reported represents (a) contributions pursuant to the CBI
    Salaried Employee Stock Ownership Plan (1987) ("ESOP") for shares allocated
    to the executive officer's account, (b) the cost of stock allocated in the
    form of units to each executive officer's account in an irrevocable trust
    under the CBI Benefit Restoration Plan (described under the caption "Pension
    and other retirement benefits") for allocations pursuant to the ESOP which
    otherwise exceed the maximum limit imposed upon such plan by the Internal
    Revenue Code (the "Code"), and (c) the dollar value of split-dollar life
    insurance benefits. Those three amounts, expressed in the same order
    identified above, for each named executive officer are

(1) It is the present policy of the Compensation Committee not to award SARs
    either at the time of grant or during the term of the option.
 
(2) All options were granted at market value and are subject to a one-year
    holding period. Each option will terminate and cease to be exercisable if
    the Participant's employment with the Company terminates for any reason
    other than death, retirement for disability or retirement under a retirement
    plan of the Company.
 
(3) The estimated grant date present value reflected in the above table is
    determined using the Black-Scholes model. The material assumption and
    adjustments incorporated in the Black-Scholes model in estimating the value
    of the options reflected in the above table include the following: (a) an
    exercise price of the option of $30.125 equal to the fair market value of
    the underlying stock on the date of grant; (b) an interest rate of 6.48%
    that represents that interest rate on a U.S. treasury security with a
    maturity date corresponding to that of the option term; (c) volatility of
    33.249% calculated using daily stock prices for the one-year period prior to
    the grant date; (d) dividends at the rate of $0.48 per share, representing
    the annualized dividends paid with respect to a share of Common Stock at the
    date of grant; (e) an approximately 4.0% reduction to reflect the
    probability of forfeiture due to termination prior to vesting and
    approximately 12.33% reduction to reflect the probability of a shortened
    option term due to termination of employment prior to the option expiration
    date; and (f) an option term of ten years. The ultimate values of options
    will depend on the future market price of Common Stock, which cannot be
    forecast with reasonable accuracy. The actual value, if any, an optionee
    will realize upon exercise of an option will depend on the excess of the
    market value of the Common Stock over the exercise price on the date the
    option is exercised.

                  LONG-TERM INCENTIVE PLANS -- AWARDS IN 1994
 
     Under the Company's 1994 Restricted Stock Award Plan, at the beginning of
each year, the performance goals and target awards are set. Target awards are
allocated 50% to the current year for which the target award was made ("50%
award"), 25% to the first year following ("first year award") and 25% to the
second year following ("second year award"). Target awards are subject to
adjustment based upon measurement of pre-tax operating income as a return on net
assets over a three year period ending with the year in which the measurement
performance is made. The 50% award is adjusted at the end of the year in which
the target award is made. The first year award is adjusted at the end of the
year in which the target award is made and at the end of the subsequent year.
The second year award is adjusted at the end of the year in which the target
award is made and again at the end of the second year following the year the
target award is made. The target award, as it may be adjusted, will be earned if
100% of the performance goal is achieved. The threshold number of shares will be
earned at the achievement of 75% of the performance goal, and the maximum number
of shares will be earned at the achievement of 125% of the performance goal. No
dividends will be paid during the performance period.

     Pensions for salaried employees, including Executive Officers, are based on
years of service and the greater of the average of their last thirty-six
consecutive months or any three consecutive full calendar years of salary and
bonuses (excluding profit-sharing, overseas living adjustments, remuneration
related to Company securities, and compensation otherwise constituting qualified
earnings in excess of an annually adjusted limitation imposed by the Internal
Revenue Code.)
 
     Pension benefits are computed on the basis of a single life annuity with a
surviving spouse benefit. Pension Plan benefits shown above are offset by a
portion of primary Social Security benefits. In the case of all the named
executive officers, such reduction would not substantially affect their
benefits. Benefits are also offset by an amount equal to the amount of a monthly
annuity that could have been purchased from an insurance company at the time a
participant retires with one-half the cash value of the participant's ESOP
account up to a maximum of one-half the pension accrued by the participant after
1987.
 
     The Internal Revenue Code limited the annual benefits which may be paid to
any person under the Pension Plan to $120,000 per year in 1994. In addition,
compensation to be used in the determination of benefits was limited by the
Internal Revenue Code to $150,000 for 1994. The Company has adopted the CBI
Benefit Restoration Plan through which it pays retirement benefits otherwise
determined under the Pension Plan formulas but in excess of the maximum limit
imposed upon qualified pension plans by the Internal Revenue Code. Certain
assets have been placed in trust with an independent trustee to support the CBI
Benefit Restoration Plan. The Company may not unilaterally amend such trust
after a defined change in control of the Company and may not revoke the trust in
any event.

     The number of years of credited service, as of December 31, 1994, for the
named executive officers are: John E. Jones, 37.7 years; George L. Schueppert,
29.4 years; Lewis E. Akin, 34.3 years; Robert J. Daniels, 28.9 years; and
Charles O. Ziemer, 32.3 years. Pursuant to an agreement between Mr. Jones and
the Company, the years credited to him include years of service with his former
employer, but any pension payable by the Company to him will be offset by any
pension he receives from his former employer.
 
COMPENSATION OF DIRECTORS
 
     Directors who were not officers of the Company received in 1994 an annual
retainer of $20,000, paid in quarterly installments, plus an amount equal to the
value of 300 shares of Common Stock, valued on the first business day of July,
which each eligible director in 1994 elected to take in the form of shares of
Common Stock, and $1,000 for attendance at each Board meeting. Directors who
were chairpersons of committees received in 1994 an additional retainer of
$4,000. Those who serve on Board Committees receive $1,000 for each Committee
meeting attended. Directors who are not employees of the Company may elect on an
annual basis to defer their fees. Such electing director is credited with
investment units equivalent to the number of shares of Common Stock that could
have been purchased on the open market with the amounts to which the director
was entitled under the standard compensation arrangements plus credit for
dividends that would have been paid on such shares.
 
TERMINATION AGREEMENTS
 
     Agreements between the Company and Messrs. Jones, Akin, Willoughby,
Schneider and Ziemer provide for each executive's continued employment for a
three year period (or to age 65, if earlier) following a Change in Control of
the Company ("Change in Control Agreements"). "Change in Control" is defined as
the occurrence at any time of any of the following events: an Acquiring Person
(as defined below) has become such; or (b) Continuing Directors (as defined
below) cease to comprise a majority of the Board of Directors of the Company.
The term "Acquiring Person" means any Person (as defined) who or which, together
with all Affiliates (as defined) and Associates (as defined) of such Person,
shall be the Beneficial Owner (as defined) of 10% or more of the Shares then
outstanding (subject to certain exceptions), but shall not include an Exempt
Person (as defined). The term "Continuing Director" means any member of the
Board, while such person is a member of the Board, who is not an Acquiring
Person, or an Affiliate or Associate of an Acquiring Person, or a representative
of an Acquiring Person or of any such Affiliate or Associate, and was a member
of the Board prior to March 4, 1986 and means any person who subsequently
becomes a member of the Board, while such person is a member of the Board, who
is not an Acquiring Person, or an Affiliate or Associate of an Acquiring Person,
or a representative of an Acquiring Person or of any such Affiliate or
Associate, if (a) such person's nomination for election or election to the Board
is recommended or approved by resolution of a majority of the Continuing
Directors or (b) such person is included as a nominee in a proxy statement of
the Company distributed when a majority of the Board consists of Continuing
Directors.
 
     Compensation and benefits for the three-year period are based generally on
the executive's compensation and benefits before the Change in Control, subject
to stipulated increases, and are payable in a lump sum on a discounted present
value basis upon either (i) termination by the Company of the executive's
employment for any reason other than death, disability or wilful and material
breach of the agreement during such period, or (ii) resignation of the executive
following any of (a) a significant change in the executive's authorities or
duties, (b) a reduction in the executive's total compensation and (c) other
breach of the executive's Change in Control Agreement. Such benefits payable
upon a termination of employment following a Change in Control also include a
cash payment equal to (a) the fair market value of any restricted stock awards
which are forfeited as a result of such termination, and (b) with respect to any
stock option that ceases to be exercisable or which terminates, a payment equal
to the excess of the fair market value of the stock subject to such option over
the option exercise price. The Change in Control Agreement also contains
"gross-up" provisions pursuant to which the executive will be paid additional
amounts to reimburse such executive for all excise taxes payable pursuant to
Code Section 4999 with respect to so-called golden parachutes, which additional
payments will also include those amounts necessary to permit the executive to
pay all income and excise taxes payable with respect to all such additional
payments.

     Pursuant to addenda to their respective Change in Control Agreements with
the Company, L.E. Akin and C.E. Willoughby also entered into Change in Control
Agreements with their current employers, Chicago Bridge & Iron Company ("CBIC")
and Liquid Carbonic Industries Corporation ("LCI"), respectively, wholly owned
subsidiaries of the Company. Messrs. Akin's and Willoughby's Change of Control
Agreements become effective upon either a Change in Control of the Company or a
Change in Ownership of CBIC or LCI, as the case may be. A "Change in Ownership"
of CBIC or LCI means an occurrence of an event pursuant to which the ultimate
right to elect the directors of CBIC or LCI, as the case may be, is not
exercisable by the Company or another entity which directly or indirectly
acquires stock of CBIC or LCI, as the case may be, in a leveraged buyout in
which the senior management of the Company participates. Upon the earlier of a
Change in Control in the Company, or a Change in Ownership of CBIC or LCI, as
the case may be, the executive officer must, within 30 days of such change,
notify both its immediate employer and the Company as to which employment
arrangement the executive wishes to apply to his employment.
 
            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     The Compensation Committee of the Board of Directors (the "Committee") is
composed entirely of outside directors and is responsible for reviewing and
approving compensation practices and benefits, in particular those affecting the
executive and management group of employees of the Company and its subsidiaries,
and including recommendations proposed by management. The Committee determines
compensation and awards and grants under corporate plans for officers of the
Company (subject to review by the Board of Directors), reviews management
recommendations concerning compensation for certain other executives, and
administers the Company's stock option plans, the CBI Officers' Bonus Plan and
the CBI 1994 Restricted Stock Award Plan.
 
     The Committee uses the services of Hewitt Associates LLC, a
nationally-recognized, independent compensation consultant which provides
relevant competitive compensation data, to assist the Committee in making its
decisions. The consultant conducts an annual review of the Company's executive
compensation program and reports its findings to the Committee. This review is
based on a study of the current comparative compensation practices of an
appropriate sample of other large public corporations comparable in size to the
Company. Throughout this report, reference to "competitive data," "market
levels," "market data," etc., is reference to the information and values
provided by this study. The Company relies on this array of companies for
analysis of executive compensation rather than the Peer Group chosen for
comparing stockholder return in the Performance Graph because the Committee
believes the Company's competition for executive talent, based on both the
Company's geographic location and the industries in which the Company operates,
is better reflected by this array of companies.
 
OVERALL COMPENSATION PHILOSOPHY
 
     The Company's executive compensation program is designed to support the
achievement of corporate performance goals, to attract, retain and motivate
talented people, and to link executive and shareholder interests through
equity-based plans with a long-term perspective. The program consists of short
and long-term incentive plans which emphasize pay for both individual and
corporate performance and stock based incentives. Because the Committee believes
that it is in the best interest of shareholders to operate the business with a
long term perspective and reward those who do so, the program is intended to
more greatly emphasize its longer-term components. Cash compensation, which
includes base salary and bonus, is designed to be at or near competitive market
levels with base salaries approaching market levels and annual target
performance bonus opportunities at market levels. Long-term incentives, which
are a) stock option grants and b) restricted stock awards based on longer-term
corporate performance, are designed to provide opportunity for resulting
compensation from such incentives at or above the median values indicated by the
competitive data and to provide an incentive to an executive which is aligned
with shareholder interests.
 
     The following is a detailed description of the current compensation
program.
 
                                       14
<PAGE>   21
 
BASE SALARY
 
     The Committee annually reviews the salaries of the executive officers of
the Company. In determining appropriate salary levels, the Committee primarily
considered (weighing all the factors on a generally equivalent basis) level of
responsibility, experience, individual performance, and competitive pay levels
as reflected in the compensation consultant's study.
 
ANNUAL INCENTIVES
 
     Through the CBI Officers' Bonus Plan, annual incentive bonus opportunities
are made available to executive officers, including the CEO, to recognize and
reward corporate, business unit, and individual performance. The plan provides
incentives to executive officers of the Company by making cash payments to those
who achieve their business unit and/or Company annual goals and a discretionary
payment for individual performance as described below.
 
     The performance portion of the plan uses income and return on invested
capital performance goals for the Company. Threshold, target and maximum goals
for Company and business unit performances are established at the beginning of
each year. An executive's target bonus depends upon his position,
responsibility, and ability to impact the achievement of the Company's
performance goals. The competitive market data is reviewed annually in
considering appropriate levels of incentive bonus opportunities for individual
employees. The Committee annually reviews and approves the plan's target
opportunities and performance goals.
 
     Annual incentive bonus opportunities are made available pursuant to the
discretionary portion of the CBI Officers' Bonus Plan by permitting cash
payments to executive officers for the effort and skill exhibited in supervising
their respective areas of responsibility and the personnel who report to them.
Individual target and maximum amounts payable under this portion of the Plan are
established and approved by the Committee.
 
     In 1994, the Company and its business units' performance goals were
exceeded, and the amounts paid consisted of both a performance portion and a
discretionary portion under the Plan.
 
STOCK OPTION PLAN AND RESTRICTED STOCK AWARD PLAN
 
     The overall compensation philosophy is to stress long-term stock based
incentives related to shareholder value. Opportunities for such incentives are
provided in the form of stock options and restricted stock at a level targeted
slightly above competitive market levels.
 
STOCK OPTION PLAN
 
     Stock options are granted under the CBI Stock Option Plan to encourage and
reward long-term corporate financial success, as measured by stock price
appreciation. Under the plan, the Committee annually considers grants to
executives of options to purchase shares of Company stock at the closing market
price on the day of the grant. These grants may be exercised after one year and
up to a maximum of ten years from date of grant. The number of shares granted to
an individual employee is based on, in general order of importance, the
employee's potential impact on the Company's performance based upon the
employee's position and level of responsibility, a qualitative evaluation of the
employee's past performance, a review of the competitive compensation data and
the number of options granted in previous years.
 
RESTRICTED STOCK AWARD PLAN
 
     The Restricted Stock Award Plan is intended to encourage long-term
employment and provide incentive compensation to Participants over an extended
period by using a combination of specific longer-term financial goals and stock
vesting restrictions. The Plan provides for awarding a target number of
restricted shares to an individual recipient, or a percentage thereof, only
after the Company achieves the performance goals set by the Committee.
Restrictions on shares awarded lapse at the beginning of the fifth year
following the year for which performance is measured. Assignment of a target
award of restricted stock to an individual employee is based on, in general
order of importance, the employee's potential impact on the Company's
performance based upon the employee's position and level of responsibility, a
qualitative evaluation of the employee's past
 
                                       15
<PAGE>   22
 
performance, a review of the competitive compensation data and the number of
restricted shares awarded in previous years. The performance goal is based on
pre-tax operating income, as a return on net assets. The Committee each year
also approves the levels of the target awards. In 1994, the Company exceeded its
performance goals under the Plan.
 
CEO COMPENSATION
 
     Mr. John Jones has been Chairman, CEO and President of CBI Industries since
1989. Mr. Jones' 1994 base salary was $530,000, the same as in 1993. In light of
the financial results for 1993, Mr. Jones recommended to the Committee no
adjustment to his salary for 1994, and upon consideration the Committee
accordingly granted no salary increase to him. The amount of Mr. Jones' 1994
base salary remained slightly below the median value as reflected in the
competitive data of the compensation study.
 
     Based on 1994 financial results, Mr. Jones earned an incentive bonus of
$552,497. This amount was up from the $77,000 paid for 1993, which consisted
solely of a bonus paid under the discretionary portion of the Plan. As the
corporate performance goals under the CBI Officers' Bonus Plan were exceeded in
1994, this amount consisted of both a performance-based portion and a
discretionary portion under the Plan. Mr. Jones' bonus target was set as a
percentage of his base salary, taking into consideration the competitive data
for such targets, with most of the amount paid based upon net income and return
on invested capital performance goals for the Company, and a discretionary
portion. The discretionary portion of Mr. Jones' bonus was based on the
Committee's consideration of Mr. Jones' leadership in long-term strategic
planning, his focus on the increasing global market opportunities for the
Company, and his management ability as the Company undergoes change to adapt to
these conditions. The total amount paid to Mr. Jones could have ranged from a
minimum of 0% to a maximum of 114% of his base pay, depending on the degree of
achievement of net income and return on invested capital performance goals, and
the amount of the discretionary portion under the Plan.
 
     The 1994 stock option grant of 31,000 shares to Mr. Jones was based on his
potential impact on the Company's performance based upon his position and level
of responsibility within the Company, and its consideration of the factors
described above relating to the discretionary bonus. The Committee also
considered the number of options granted in previous years. The potential value
represented by this grant was close to the median value of similar stock option
grants as reflected in the competitive data.
 
     In 1994, the Committee established a target of 10,000 shares for Mr. Jones
under the 1994 CBI Restricted Stock Award Plan. The amount of the target award
was determined separately from the amount of the stock option grant. The
Committee also considered the number of restricted shares awarded under previous
plans in previous years in setting Mr. Jones' 1994 target award under the Plan.
The amount of the target award was slightly above the median value as reflected
in the competitive data of the compensation study. Taken together, the value of
the options granted and the restricted stock target award was slightly above the
median value of total long term incentive compensation as reflected in the
compensation study. Based upon 1994 financial results, Mr. Jones earned a
restricted stock award of 11,200 shares, of which 5,600 shares were awarded
subject to restrictions and 5,600 shares are subject to adjustment based upon
attainment of the performance goals for 1995 and 1996.
 
INTERNAL REVENUE CODE LIMITATION ON DEDUCTIBILITY OF COMPENSATION
 
     The Committee has discussed and considered certain provisions of Section
162(m) of the Internal Revenue Code of 1986, as amended, relating to the
deduction of compensation-related expenses in excess of $1,000,000. The
Committee has determined not to take further action at this time with regard to
the Company's executive compensation programs. It will continue to consider
these Code provisions with regard to such programs and any changes to them;
however, the Committee believes the Company's interests are best served by
retaining a flexible approach and that there may be circumstances in which it is
appropriate to pay certain amounts or forms of compensation that will not be
fully deductible under these Code provisions.

Dear Members of the Board:
 
     We understand that CBI Industries, Inc. (the "Company"), Praxair, Inc. (the
"Bidder") and Praxair Acquisition Corp., a wholly-owned subsidiary of the Bidder
("Acquisition Sub"), have entered into an Agreement and Plan of Merger dated as
of December 22, 1995 (the "Merger Agreement") which provides, among other
things, for (i) the tender offer by Acquisition Sub for all outstanding shares
of the common stock, par value $2.50 per share, together with certain associated
rights, of the Company for consideration of $33.00 net per share in cash (the
"Tender Offer"), and (ii) the subsequent merger (the "Merger," and together with
the Tender Offer, the "Transaction") of Acquisition Sub with and into the
Company, pursuant to which each outstanding share of the common stock of the
Company (other than shares held in treasury or held by the Bidder or any of its
affiliates or as to which dissenters' rights are perfected) will be converted
into the right to receive consideration of $33.00 net per share in cash. The
terms and conditions of the Transaction are set forth in more detail in the
Merger Agreement.
 
     We have been requested by the Board of Directors of the Company to render
our opinion with respect to the fairness, from a financial point of view, to the
Company's shareholders of the consideration to be offered to such shareholders
in the Transaction. We have not been requested to opine as to, and our opinion
does not in any manner address, the Company's underlying business decision to
proceed with or effect the Transaction.
 
     In arriving at our opinion, we reviewed and analyzed: (1) the Merger
Agreement and the specific terms of the Transaction, (2) such publicly available
information concerning the Company and the Bidder which we believe to be
relevant to our inquiry, (3) financial and operating information with respect to
the business, operations and prospects of the Company furnished to us by the
Company including, without limitation, certain projections prepared by the
Company, (4) a trading history of the Company's common stock and a comparison of
that trading history with those of other companies that we deemed relevant, (5)
a comparison of the historical financial results and present financial condition
of the Company with those of other companies that we deemed relevant, and (6) a
comparison of the financial terms of the Transaction with the financial terms of
certain other transactions that we deemed relevant. In addition, in arriving at
our opinion, we have considered the results of efforts to solicit indications of
interest from third parties with respect to an acquisition of all or part of the
Company or other strategic transactions involving the Company. We also have had
discussions with the management of the Company concerning its business,
operations, assets, financial condition and prospects and undertook such other
studies, analyses and investigations as we deemed appropriate.
 
     In arriving at our opinion, we have assumed and relied upon the accuracy
and completeness of the financial and other information used by us without
assuming any responsibility for independent verification of such information and
have further relied upon the assurances of management of the Company that they
are

not aware of any facts that would make such information inaccurate or
misleading. With respect to the financial projections of the Company, upon
advice of the Company we have assumed that such projections have been reasonably
prepared on a basis reflecting the best currently available estimates and
judgments of the management of the Company as to the future financial
performance of the Company and that the Company will perform substantially in
accordance with such projections. In arriving at our opinion, we have not
conducted a physical inspection of the properties and facilities of the Company
and have not made or obtained any evaluations or appraisals of the assets or
liabilities of the Company. Our opinion is necessarily based upon market,
economic and other conditions as they exist on, and can be evaluated as of, the
date of this letter.
 
     Based upon and subject to the foregoing, we are of the opinion as of the
date hereof that, from a financial point of view, the consideration to be
offered to the shareholders of the Company in the Transaction is fair to such
shareholders.
 
     We have, in the past, provided financial advisory and financing services to
the Company and are acting as financial advisor to the Company in connection
with the Transaction and will receive a fee for our services, a portion of which
is contingent upon the consummation of the Transaction. In addition, the Company
has agreed to indemnify us for certain liabilities that may arise out of the
rendering of this opinion. In the ordinary course of our business, we actively
trade in the securities of the Company and the Bidder for our own account and
for the accounts of our customers and, accordingly, may at any time hold a long
or short position in such securities.
 
     This opinion is for the use and benefit of the Board of Directors of the
Company. This opinion is not intended to be and does not constitute a
recommendation to any shareholder of the Company as to whether to accept the
consideration offered to such shareholder in the Transaction.

                                    RECITALS

            WHEREAS, the respective Boards of Directors of each of Praxair,

Transmittal (collectively, the "Initial Offer Documents"); and

            WHEREAS, the respective Boards of Directors of each of Praxair,
Purchaser and the Company have determined that it is in the best interests of
their respective stockholders for Purchaser to acquire the Company, upon and

<PAGE>   6

and into the Company (the "Merger") pursuant to this Agreement and the Delaware

determined that the consideration to be paid for each Share in the Amended
Offer and the Merger is fair to, and in the best interests of, the stockholders
of the Company and (ii) has approved and adopted this Agreement and the
transactions contemplated hereby and has recommended acceptance of the Amended
Offer and approval and adoption by the stockholders of the Company of this
Agreement and the Merger; and

            WHEREAS, each of the Company, Praxair and Purchaser desires to make
certain representations, warranties, covenants and agreements in connection
with this Agreement.

            NOW, THEREFORE, in consideration of the premises, and of the mutual
representations, warranties, covenants, agreements and conditions contained
herein, the parties hereto agree as follows:


                                   ARTICLE I

            The Amended Offer; Actions by the Company; Directors

            1.1.    The Amended Offer.  (a)  Praxair and Purchaser have filed
with the Securities and Exchange Commission (the "Commission") a Tender Offer
Statement on Schedule 14D-1 (the "Schedule 14D-1") with respect to the Initial
Offer which contains (included as exhibits) the Initial Offer Documents.  As
promptly as practicable (but no later than the fourth business day after the
date of this Agreement), Praxair and Purchaser shall file with the Commission
an amendment to the Initial Offer Documents (as so amended, and as the same may
be further amended or supplemented in accordance with the terms of this
Agreement, the "Amended Offer Documents").  The Company shall have the
opportunity to review the amendment to the Schedule 14D-1 to be filed in
connection with the Amended Offer prior to its being filed with the Commission.
The Amended Offer Documents shall contain a supplement to the Offer to
Purchase, which shall be mailed to the holders of Shares and which shall amend
the Initial Offer (i) to increase the price per Share payable in connection
with the Amended Offer to $33.00, (ii) to provide that the obligation of
Praxair and Purchaser to accept for payment and pay for Shares



                                      2

tendered pursuant to the Amended Offer shall only be subject to the
conditions set forth in Annex A hereto, and (iii) to change the expiration date
of the Amended Offer to midnight, New York City time, on a date that is 10
business days following the filing of the amendment (as so extended, and as it
may be extended from time to time in accordance with the terms of this
Agreement, the "Expiration Date"); it being understood and agreed that, except
for the foregoing amendments or as otherwise provided herein, the Amended Offer
shall be on the same terms as the Initial Offer.  Without the prior written
consent of the Company, Purchaser shall not decrease the price per Share or
change the form of consideration payable in the Amended Offer, decrease the
number of Shares sought or extend the Amended Offer (other than as set forth
below), amend or waive the Minimum Tender Condition (as defined in Annex A),
impose additional conditions to the Amended Offer or amend any other term of
the Amended Offer in any manner adverse to the holders of Shares.  Upon the
terms and subject to the conditions of the Amended Offer, Purchaser will accept
for payment and will purchase, as soon as permitted under the terms of the
Amended Offer, all Shares validly tendered and not withdrawn prior to the
expiration of the Amended Offer.

            (b)     Each of Praxair and Purchaser, on the one hand, and the
Company, on the other hand, agrees promptly to correct any information provided
by it for use in the Amended Offer Documents if and to the extent that it shall
have become false or misleading in any material respect, and Praxair and
Purchaser further agree to take all steps necessary to cause the Amended Offer
Documents as so corrected to be filed with the Commission and to be
disseminated to stockholders of the Company, in each case as and to the extent
required by applicable federal securities laws.

            (c)     Praxair and Purchaser agree that Purchaser shall not
terminate or withdraw the Amended Offer or extend the then scheduled Expiration
Date unless at the Expiration Date the conditions to the Amended Offer
described in Annex A hereto shall not have been satisfied or earlier waived.
If at the Expiration Date, the conditions to the Amended Offer described in
Annex A hereto shall not have been satisfied or earlier waived, Purchaser may
and, if requested by the Company, shall extend the Expiration Date on one or
more occasions for an additional period or periods of time until the earlier of
(i) the date which is sixty business days following the date of the Amended
Offer or (ii) the date this Agreement is terminated in accordance with its
terms; provided, that, this sentence shall not be applicable in the event the
conditions set forth in


                                      3

<PAGE>   8

paragraph (v)(g) of Annex A hereto shall not have been satisfied or earlier
waived at the Expiration Date.  Praxair and Purchaser shall use their
reasonable best efforts to consummate the Amended Offer in accordance with the
terms of this Agreement and the conditions to the Amended Offer set forth in
Annex A.

            1.2.    Actions by the Company.  (a)  The Company hereby approves
of and consents to the Amended Offer and represents that (i) the Board by vote
of all directors at a meeting duly called and held, has, in light of and
subject to the terms and conditions set forth herein, unanimously (x)
determined that each of the Amended Offer and the Merger is fair to, and in the
best interests of, the stockholders of the Company and (y) approved this
Agreement and the transactions contemplated hereby, including the Amended Offer
and the Merger, and recommends acceptance of the Amended Offer and approval and
adoption of this Agreement and the Merger by the stockholders of the Company
and (ii) Merrill Lynch & Co.  ("Merrill Lynch") and Lehman Brothers Inc.
("Lehman Bros."), the Company's financial advisors, have rendered to the Board
their respective opinions that the consideration to be received by the
stockholders of the Company pursuant to the Amended Offer and the Merger is
fair to such stockholders from a financial point of view.

            (b)     The Company agrees that it shall, on the same day that
Purchaser and Praxair file with the Commission an amendment to the Initial
Offer Documents pursuant to Section 1.1 hereof, file with the Commission an
amendment to its Solicitation/Recommendation Statement on Schedule 14D-9, dated
November 16, 1995 (including exhibits, as so amended, and as amended from time
to time, the "Amended Schedule 14D-9"), which amendment shall include (i)
subject to the proviso in the second sentence of Section 1.2(c), the
recommendation described in Section 1.2(a) hereof and (ii) the information with
respect to the Company and its officers and directors, (including any directors
to be elected or appointed pursuant to Section 1.3 hereof) in form and
substance satisfactory to Praxair and its counsel, that is required under
Section 14(f) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act") and Rule 14f-1 promulgated thereunder.  In such connection, Praxair and
Purchaser shall promptly furnish the Company with all information concerning
their designees required by Section 14(f) of the Exchange Act and Rule 14f-1
thereunder.  Praxair and Purchaser shall have the opportunity to review the
Amended Schedule 14D-9 prior to its being filed with the Commission.


                                      4

<PAGE>   9

            (c)     The Company agrees that copies of such Schedule 14D-9
(excluding exhibits), shall be enclosed with the Amended Offer Documents to be
mailed by Purchaser to the stockholders of the Company in connection with the
Amended Offer.  Each of the Company, on the one hand, and Praxair and
Purchaser, on the other hand, agrees promptly to correct any information
provided by either of them for use in the Amended Schedule 14D-9 if and to the
extent that it shall have become false or misleading in any material respect,
and the Company further agrees to take all steps necessary to cause the Amended
Schedule 14D-9 as so corrected to be filed with the Commission and to be
disseminated to the stockholders of the Company, in each case as and to the
extent required by applicable federal securities laws; provided, however, that,
subject to the provisions of Article IX, such recommendation may be withdrawn,
modified or amended to the extent that the Board deems it necessary to do so in
the exercise of its fiduciary and other legal obligations after being so
advised by outside counsel.   In connection with the Amended Offer, the Company
will furnish Praxair and Purchaser with such information, including lists of
the stockholders of the Company, mailing labels and lists of security
positions, and such assistance as Praxair or Purchaser or their agents may
request in communicating the Amended Offer to the record and beneficial holders
of the Shares.

            1.3.    Directors.  Promptly upon the purchase of and payment for
any Shares by Purchaser pursuant to the Amended Offer which represent at least
a majority of the Shares (on a fully diluted basis) and from time to time
thereafter, Praxair and Purchaser shall be entitled to designate members of the
Board such that Praxair and Purchaser, subject to compliance with Section 14(f)
of the Exchange Act, will have a number of representatives on the Board,
rounded up to the next whole number, equal to the product of (x) the total
number of directors on the Board multiplied by (y) the percentage of the
outstanding Shares beneficially owned by Purchaser or its affiliates; provided,
that, any action to be taken prior to the Effective Time (as defined in Section
2.3 hereof) by the Board with respect to this Agreement shall be approved by a
majority of those directors of the Company who have not been designated by
Praxair or Purchaser.  Notwithstanding the foregoing, until the Effective Time,
the Company and Praxair shall use all reasonable efforts to retain as members
of Company's Board of Directors at least two directors who at the time are
neither officers of Praxair or the Company (or any of their respective
affiliates), nor designees of Purchaser (or any of its affiliates), nor
shareholders or affiliates of Purchaser (or any respective affiliate) (the
"Disinterested


                                      5

<PAGE>   10

Directors").  The Company shall, upon request by Praxair or Purchaser, promptly
increase the size of the Board to the extent permitted by the Company's
Restated Certificate of Incorporation (the "Company Charter") and, to the
extent required to comply with this Section 1.3, secure the resignations of
such number of directors as is necessary to enable Praxair's designees to be
elected to the Board and shall cause Praxair's designees to be so elected.

                      The Merger; Closing; Effective Time

            2.1.    The Merger.  Upon the terms and subject to the conditions
set forth in this Agreement, at the Effective Time (as defined in Section 2.3
hereof) Purchaser shall be merged with and into the Company and the separate
corporate existence of Purchaser shall thereupon cease.  The Company shall be
the surviving corporation in the Merger (sometimes hereinafter referred to as
the "Surviving Corporation") and shall continue to be governed by the laws of
the State of Delaware, and the separate corporate existence of the Company with

               Conversion or Cancellation of Shares in the Merger

            5.1.    Conversion or Cancellation of Shares.  The manner of
converting or canceling shares of the Company and Purchaser in the Merger shall
be as follows:

            (a)     Conversion of Shares; Merger Consideration.  At the
Effective Time, each Share issued and outstanding immediately prior to the
Effective Time (other than Shares owned by Praxair, Purchaser or any other
Subsidiary (as defined in Section 6.1(a) hereof) of Praxair (collectively, the
"Praxair Companies")) or Shares which are held by stockholders ("Dissenting
Stockholders") exercising appraisal rights pursuant to Section 262 of the DGCL)
shall, by virtue of the Merger and without any action on the part of the holder
thereof, be converted into the right to receive, without interest, an amount in
cash (the "Merger Consideration") equal to $33.00 or such greater amount which
may be paid pursuant to the Amended Offer.  All such Shares, by virtue of the
Merger and without any action on the part of the holders thereof, shall no
longer be outstanding and shall be canceled and retired and shall cease to
exist, and each holder of a certificate representing any such Shares shall
thereafter cease to have any rights with respect to such Shares, except the
right to receive the Merger Consideration for such Shares upon the surrender of
such certificate in accordance with Section 5.2 or the right, if any, to
receive payment from the Surviving Corporation of



                                      8
<PAGE>   13

the "fair value" of such Shares as determined in accordance with
Section 262 of the DGCL.

            (b)     Cancellation of Shares.  At the Effective Time, each Share
issued and outstanding at the Effective Time and owned by any of the Praxair
Companies, and each Share issued and held in the Company's treasury at the
Effective Time, shall, by virtue of the Merger and without any action on the
part of the holder thereof, cease to be outstanding, shall be canceled and
retired without payment of any consideration therefor and shall cease to exist.

            (c)     Conversion of Purchaser Common Stock.  At the Effective
Time, each share of Common Stock, par value $0.01 per share, of Purchaser
issued and outstanding immediately prior to the Effective Time shall, by virtue
of the Merger and without any action on the part of Purchaser or the holders of
such shares, be converted into one issued and outstanding share of common stock
of the Surviving Corporation.

            (d)     Convertible Preferred Stock.  At the Effective Time, each
share of $2.27 Convertible Voting Preferred Stock, Series C of the Company, par
value $1.00 per share (the "Convertible Preferred Shares"), shall remain
outstanding and shall be entitled to the same dividend and other relative
rights, preferences, limitations and restrictions as are now provided by the
Company Charter; provided, that, after the Effective Time, the Convertible
Preferred Shares shall no longer be convertible into Shares; and provided,
further, that each Convertible Preferred Share shall be convertible, after the
Effective Time, into the amount of cash that the holder thereof might have been
entitled to receive if such holder had converted such Convertible Preferred
Shares into Shares immediately prior to the Effective Time.

            (e)     Cumulative Preferred Stock.  Each share of 7.48% Cumulative
Preferred Stock, Series D of the Company, par value $1.00 per share (the
"Series D Preferred Shares"), and $6.75 Cumulative Preferred Stock, Series E of
the Company, par value $1.00 per share (the "Series E Preferred Shares" and
together with the Series D Preferred Shares, the "Cumulative Preferred Shares"
and the Cumulative Preferred Shares, together with the Convertible Preferred
Shares and the Junior Participating Preferred Stock, Series A of the Company,
par value $1.00 per share, the "Preferred Shares"), which immediately prior to
the Effective Time is issued and outstanding shall remain outstanding and shall
be entitled to the same dividend and other relative rights, preferences,



                                      9
<PAGE>   14

limitations and restrictions as are now provided by the Company Charter.

            5.2.    Payment for Shares.  Praxair shall make available or cause
to be made available to the paying agent appointed by Praxair (the "Paying
Agent") amounts sufficient in the aggregate to provide all funds necessary for
the Paying Agent to make payments pursuant to Section 5.1(a) hereof to holders
of Shares issued and outstanding immediately prior to the Effective Time.
Promptly after the Effective Time, the Surviving Corporation shall cause to be
mailed to each Person who was, at the Effective Time, a holder of record (other
than any of the Praxair Companies) of issued and outstanding Shares a form
(mutually agreed to by Purchaser and the Company) of letter of transmittal and
instructions for use in effecting the surrender of the certificates which,
immediately prior to the Effective Time, represented any of such Shares in
exchange for payment therefor.  Upon surrender to the Paying Agent of such
certificates, together with such letter of transmittal, duly executed and
completed in accordance with the instructions thereto, the Surviving
Corporation shall promptly cause to be paid to the persons entitled thereto a
check in the amount to which such persons are entitled, after giving effect to
any required tax withholdings.  No interest will be paid or will accrue on the
amount payable upon the surrender of any such certificate.  If payment is to be
made to a Person other than the registered holder of the certificate
surrendered, it shall be a condition of such payment that the certificate so
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the Person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a Person other than the registered
holder of the certificate surrendered or establish to the satisfaction of the
Surviving Corporation or the Paying Agent that such tax has been paid or is not
applicable.  One hundred and eighty days following the Effective Time, the
Surviving Corporation shall be entitled to cause the Paying Agent to deliver to
it any funds (including any interest received with respect thereto) made
available to the Paying Agent which have not been disbursed to holders of
certificates formerly representing Shares outstanding on the Effective Time,
and thereafter such holders shall be entitled to look to the Surviving
Corporation only as general creditors thereof with respect to the cash payable
upon due surrender of their certificates.  Notwithstanding the foregoing,
neither the Paying Agent nor any party hereto shall be liable to any holder of
certificates formerly representing Shares for any amount paid to a public
official pursuant to any applicable abandoned property, escheat or similar law.
The Surviving



                                      10
<PAGE>   15

Corporation shall pay all charges and expenses, including those of the Paying
Agent, in connection with the exchange of cash for Shares and Praxair shall
reimburse the Surviving Corporation for such charges and expenses.

            For the purposes of this Agreement, the term "Person" shall mean
any individual, corporation (including not-for-profit), general or limited
partnership, limited liability company, going venture, estate, trust,
association, organization, Governmental Entity (as defined in Section 6.1(d))
or other entity of any kind or nature.

            5.3.    Dissenters' Rights.  If any Dissenting Stockholder shall be
entitled to be paid the "fair value" of his or her Shares, as provided in
Section 262 of the DGCL, the Company shall give Praxair notice thereof and
Praxair shall have the right to participate in all negotiations and proceedings
with respect to any such demands.  The Company shall give Praxair prompt notice
of any demands received by the Company for appraisal of Shares and Praxair
shall have the right to participate in all negotiations and proceedings with
respect to such demands.  Neither the Company nor the Surviving Corporation
shall, except with the prior written consent of Praxair, voluntarily make any
payment with respect to, or settle or offer to settle, any such demand for
payment.  If any Dissenting Stockholder shall fail to perfect or shall have
effectively withdrawn or lost the right to dissent, the Shares held by such
Dissenting Stockholder shall thereupon be treated as though such Shares had
been converted into the Merger Consideration pursuant to Section 5.1 hereof.

            5.4.    Transfer of Shares After the Effective Time.  No transfers
of Shares shall be made on the stock transfer books of the Surviving
Corporation at or after the Effective Time.


                                   ARTICLE VI

                         Representations and Warranties

            6.1.    Representations and Warranties of the Company.  The Company
hereby represents and warrants to  Praxair and Purchaser that, except as set
forth in the disclosure letter delivered to Praxair by the Company on or prior
to entering into this Agreement (the "Company Disclosure Letter"):

            (a)     Organization, Good Standing and Qualification.  Each of the
Company and its Subsidiaries (as defined

operate its properties and assets and to carry on its business as presently
conducted and is qualified to do business and is in good standing as a foreign
corporation in each jurisdiction where the ownership or operation of its
properties or conduct of its business requires such qualification, except where
the failure to be so qualified or in good standing will not, when taken
together with all other such failures have a Company Material Adverse Effect
(as defined below).  The Company has made available to Praxair a complete and
correct copy of the Company's certificate of incorporation and by-laws, each as
amended to date.  The Company's certificate of incorporation and by-laws so
delivered are in full force and effect.  Section 6.1(a) of the Company
Disclosure Letter contains a correct and complete list of each of its
Subsidiaries (except for such Subsidiaries that are immaterial) and each
jurisdiction where the Company and each of its Subsidiaries is organized.

            As used in this Agreement, (i) the term "Subsidiary" means, with
respect to the Company, Praxair or Purchaser, as the case may be, any entity,
whether incorporated or unincorporated, domestic or foreign, of which at least
a majority of the securities or ownership interests having by their terms

Company consists of 240,000,000 Shares and 20,000,000 shares of preferred
stock, par value $1.00.  As of September 30, 1995, there were issued and
outstanding 38,295,207 Shares; 3,484,713 Convertible Preferred Shares; 550,000

authorized and are validly issued, fully paid and nonassessable and free of
preemptive rights with respect thereto.  As of September 30, 1995, 1,488,407
Shares were held in the treasury of the Company.  As of the date hereof,



                                      12

the CBI 1983 Restricted Stock Award Plan, the CBI 1989 Restricted Stock Award

Rights Agreement (which agreement will be amended as described in Section
7.10(a) hereof), and Shares reserved for issuance pursuant to the Company's
1994 Restricted Stock Award Plan, effective March 9, 1994.  Section 6.1(b) of
the Company Disclosure Letter contains a correct and complete list of each
outstanding option to purchase Shares under the Stock Plans (each a "Company
Option"), including the holder, date of grant, exercise price, the number of
Shares subject thereto and the number of stock appreciation rights, if any,
granted in respect of such Company Option.  Except as set forth in Section
6.1(b) of the Company Disclosure Letter, each of the outstanding shares of
capital stock or other securities of each of the Company's Subsidiaries is duly
authorized, validly issued, fully paid and nonassessable and owned by a direct
or indirect wholly-owned subsidiary of the Company, free and clear of any lien,
pledge, security interest, claim or other encumbrance.  Except as set forth

Letter, there are no preemptive or other outstanding rights, options, warrants,
conversion rights, stock appreciation rights, redemption rights, repurchase
rights, agreements, arrangements or commitments to issue or sell any shares of

            (c)     Corporate Authority; Approval and Fairness.  The Company
has full requisite corporate power and authority and has taken all corporate
action necessary in order to execute, deliver and perform its obligations under
this Agreement and to consummate, subject only to approval of this Agreement by
the Company Requisite Vote (as defined in Section 6.1(k) hereof), the
transactions contemplated hereby.  The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly and
validly authorized and approved by the Board, and other than the Company
Requisite Vote (as defined in Section 6.1(k)), no other corporate proceedings
are necessary to authorize this Agreement or the consummation of the
transactions contemplated hereby.  Assuming this Agreement constitutes a legal,
valid and binding agreement of Praxair and Purchaser, this Agreement
constitutes a legal, valid and binding agreement of the Company enforceable
against the Company in accordance with its terms, except as enforcement may be
limited by general principles of equity, whether applied in a court of law or a
court of equity, and by bankruptcy, insolvency and similar laws affecting
creditors' rights and remedies generally.

            (d)     Governmental Filings; No Violations.  (i)  Other than the
filings and/or notices (A) pursuant to Section 2.3 hereof, (B) under the

change of control, notification, competition or other laws of jurisdictions
listed in Section 6.1(d) of the Company Disclosure Letter (collectively, the
"Regulatory Filings"), no notices, reports or other filings are required to be
made by the Company with, nor are any consents, registrations, approvals,
permits or authorizations required to be obtained by the Company from, any
government or governmental, regulatory or administrative authority or agency,
domestic, foreign or supranational (each, a "Governmental Entity"), in
connection with the execution and delivery of this Agreement by the Company and



                                      14
<PAGE>   19

the consummation by Purchaser of the Amended Offer and by the Company of the
Merger and the other transactions contemplated hereby, except those the failure
to make or obtain that are not, individually or in the aggregate, reasonably
likely to have a Company Material Adverse Effect or prevent, materially delay
or materially impair the ability of the Company or the Purchaser to consummate
any of the transactions contemplated by this Agreement.

            (ii)    The execution, delivery and performance of this Agreement
by the Company do not, and the consummation by the Company of the Merger
pursuant to the terms of this Agreement and the other transactions contemplated
hereby will not, except as set forth in Section 6.1(d) of the Company
Disclosure Letter, constitute or result in (A) a breach or violation of, or a

comparable governing instruments of any of their Subsidiaries, (B) a breach or
violation of, or a default under, the vesting, creation or acceleration of any

agreement, lease, contract, note, mortgage, indenture, arrangement or other
domestic or foreign obligation ("Contracts") of the Company or any of its
Subsidiaries or any Law (as defined in Section 6.1(i)) or governmental or
non-governmental permit or license to which the Company or any of its
Subsidiaries is subject or (C) any change in the rights or obligations of any
party under any of the Contracts, except, in the case of clause (B) or (C)
above, for any breach, violation, default, acceleration, creation or change
that, individually or in the aggregate, will not have a Company Material
Adverse Effect or prevent, delay or impair the ability of the Company to
consummate the transactions contemplated by this Agreement.  Section 6.1(d) of
the Company Disclosure Letter sets forth a correct and complete list of
Contracts of the Company and its Subsidiaries pursuant to which consents or
waivers are or may be required prior to consummation of the transactions
contemplated by this Agreement (subject to the exception set forth with respect
to clauses (B) and (C) above).  The Company will use its reasonable best
efforts to obtain the consents referred to in the Disclosure Letter.

            (e)     Company Reports; Financial Statements.  The Company has
filed with the Commission each registration statement, report, proxy statement
or information statement required to be filed by it since December 31, 1994
(the "Audit Date"), including (i) the Company's Annual Report on Form 10-K for
the year ended December 31, 1994 and (ii) the



                                      15
<PAGE>   20

Company's Quarterly Reports on Form 10-Q for the periods ended March 31, 1995,
June 30, 1995, and September 30, 1995, (collectively, including any such
reports filed subsequent to the date hereof, the "Company Reports").  As of
their respective dates, the Company Reports did not, and any Company Reports
filed with the Commission subsequent to the date hereof will not, contain any
untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements made therein, in light
of the circumstances in which they were made, not misleading.  Except as
disclosed in Section 6.1(e) of the Company Disclosure Letter, neither the
Company nor any of its Subsidiaries, nor any of their respective assets,
businesses, or operations, is as of the date of this Agreement a party to, or
is bound or affected by, or receives benefits under any contract or agreement
or amendment thereto, that in each case would be required to be filed as an
exhibit to a Form 10-K as of the date of this Agreement that has not been filed
as an exhibit to a Company Report filed prior to the date of this Agreement.
As of their respective dates, the consolidated financial statements included in
the Company Reports complied as to form in all material respects with then
applicable accounting requirements and the published rules and regulations of
the Commission with respect thereto.  Each of the consolidated balance sheets
included in or incorporated by reference into the Company Reports (including
the related notes and schedules) fairly presents the consolidated financial
position of the Company and its Subsidiaries as of its date and each of the
consolidated statements of income and of changes in cash flows included in or
incorporated by reference into the Company Reports (including any related notes
and schedules) fairly presents the results of operations and changes in cash
flows, as the case may be, of the Company and its Subsidiaries for the periods
set forth therein (subject, in the case of unaudited statements, to the absence
of notes and normal year-end audit adjustments that will not be material in
amount or effect), in each case in accordance with U.S. generally accepted
accounting principles ("GAAP") consistently applied during the periods
involved, except as may be noted therein.

            (f)     Absence of Certain Changes.  Except as disclosed in the
Company Reports prior to the date hereof and except as disclosed in Section
6.1(f) of the Company Disclosure Letter, since the Audit Date the Company and
its Subsidiaries have conducted their respective businesses only in, and have
not engaged in any material transaction other than according to, the ordinary
and usual course of such businesses and there has not been (i) any change in
the financial condition, business, prospects or results of



                                      16
<PAGE>   21

operations of the Company and its Subsidiaries, except those changes that will
not, individually or in the aggregate, have a Company Material Adverse Effect;
(ii) any material damage, destruction or other casualty loss with respect to
any material asset or property owned, leased or otherwise used by the Company
or any of its Subsidiaries, whether or not covered by insurance; (iii) except
for dividends that have already been declared and publicly announced on Shares
and payment of dividends on Preferred Shares in accordance with its terms, any
declaration, setting aside or payment of any dividend or other distribution in
respect of the capital stock of the Company; (iv) any change by the Company in
accounting principles, practices or methods.  Since the Audit Date, except as
provided for herein or as disclosed in the Company Reports prior to the date
hereof, there has not been any increase in the compensation payable or that
could become payable by the Company and its Subsidiaries to their officers or
key employees or any amendment of any of the Compensation and Benefit Plans (as
defined in Section 6.1(h) hereof) other than increases or amendments in the
ordinary course of business consistent with past practice.

            (g)     Litigation and Liabilities.  Except as disclosed in the
Company Reports prior to the date hereof and except as disclosed in Section
6.1(g) of the Company Disclosure Letter, there are no (i) civil, criminal or
administrative actions, suits, claims, hearings, investigations or proceedings
pending or threatened against the Company or any of its Subsidiaries or
Affiliates, in any foreign or domestic jurisdiction or (ii) obligations or
liabilities, whether or not accrued, contingent or otherwise and whether or not
required to be disclosed, including those relating to matters involving any
foreign or domestic Environmental Law (as defined in Section 6.1(l)), or any
other facts or circumstances that so far as can reasonably be foreseen could
result in any claims against or obligations or liabilities of the Company or
any of its Subsidiaries or Affiliates, except for those that are not,
individually or in the aggregate, likely to have a Company Material Adverse
Effect or prevent the Company from consummating the transactions contemplated
by this Agreement; provided, however, that since December 31, 1994 and except
as set forth in Section 6.1(g) of the Company Disclosure Letter, the Company

            (h)     Employee Benefits.

            (i)     A copy (or, if unwritten, a summary thereof) of each bonus,
deferred compensation, pension, retirement, profit-sharing, thrift, savings,
employee stock ownership, stock bonus, stock purchase, restricted stock, stock
option, employment, termination, severance, compensation, medical, health or
other plan, agreement, policy or arrangement that covers employees, directors,
former employees or former directors of the Company and its Subsidiaries and
which are sponsored, maintained or contributed to by the Company or its
Subsidiaries (and excluding multiemployer plans as defined under ERISA (as
hereinafter defined) and excluding plans in foreign jurisdictions as to which
contributions are mandatory) (the "Compensation and Benefit Plans") and any
trust agreements or insurance contracts forming a part of such Compensation and
Benefit Plans has been made available to Praxair prior to the date hereof.  The
Compensation and Benefit Plans are listed in Section 6.1(h) of the Company
Disclosure Letter.

            (ii)    All Compensation and Benefit Plans are in substantial
compliance with all applicable law, including the Code and the Employee
Retirement Income Security Act of 1974, as amended ("ERISA").  Each
Compensation and Benefit Plan that is an "employee pension benefit plan" within
the meaning of Section 3(2) of ERISA (a "Pension Plan") and that is intended to
be qualified under Section 401(a) of the Code has received a favorable
determination letter from the Internal Revenue Service (the "IRS"), and the
Company is not aware of any circumstances likely to result in revocation of any
such favorable determination letter.  There is no pending or, to the knowledge
of the officers of the Company, threatened material litigation relating to the
Compensation and Benefit Plans.  Neither the Company nor any Subsidiary has
engaged in a transaction with respect to any Compensation and Benefit Plan
that, assuming the taxable period of such transaction expired as of the date
hereof, would subject the Company or any of its Subsidiaries to a material tax
or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA.

            (iii)   Except as disclosed in Section 6.1(h) of the Company
Disclosure Letter, as of the date hereof, no liability under Subtitle C or D of
Title IV of ERISA has been or is expected to be incurred by the Company or any
Subsidiary with respect to any ongoing, frozen or terminated "single-employer
plan", within the meaning of Section 4001(a)(15) of ERISA, currently or
formerly maintained by any of them, or the single-employer plan of any entity
which is considered one employer with the Company



                                      18
<PAGE>   23

under Section 4001 of ERISA or Section 414 of the Code (an "ERISA
Affiliate"), except for such a liability that has as of the date hereof been
satisfied.  Except as set forth in Section 6.1(h) of the Company Disclosure
Letter, the Company and its Subsidiaries have not incurred and do not expect to
incur any withdrawal liability with respect to a multiemployer plan under
Subtitle E to Title IV of ERISA, except for such a liability that has as of the
date hereof been satisfied.  No notice of a "reportable event", within the
meaning of Section 4043 of ERISA for which the 30-day reporting requirement has
not been waived, has been required to be filed for any Pension Plan or by any
ERISA Affiliate within the 12-month period ending on the date hereof or will be
required to be filed in connection with the transaction contemplated by this
Agreement.

            (iv)    All contributions required to be made under the terms of
any Compensation and Benefit Plan have been timely made or have been properly
reflected on the most recent consolidated balance sheet filed or incorporated
by reference in the Company Reports prior to the date hereof.  Neither any
Pension Plan nor any single-employer plan of an ERISA Affiliate has an
"accumulated funding deficiency" (whether or not waived) within the meaning of
Section 412 of the Code or Section 302 of ERISA.  Neither the Company nor its
Subsidiaries has provided, or is required to provide, security to any Pension
Plan or to any single-employer plan of an ERISA Affiliate pursuant to Section
401(a)(29) of the Code.

            (v)     Except as set forth in Section 6.1(h)(v) of the Company
Disclosure Letter, under each Pension Plan which is a single-employer plan, as
of the last day of the most recent plan year ended prior to the date hereof,
the actuarially determined present value of all "benefit liabilities", within
the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the
actuarial assumptions contained in the Pension Plan's most recent actuarial
valuation), did not exceed the then current value of the assets of such Pension
Plan, and there has been no material adverse change in the financial condition
of such Pension Plan since the last day of the most recent plan year.  Except
as set forth in Section 6.1(h)(v) of the Company Disclosure Letter, the
withdrawal liability under Subtitle E of Title I of ERISA of the Company and
its Subsidiaries under each multiemployer plan to which the Company, any of its
Subsidiaries or an ERISA Affiliate has contributed during the preceding 12
months, determined as if a "complete withdrawal", within the meaning of Section
4203 of ERISA, had occurred as of the date hereof, does not exceed $1,000,000.

            (vi)    Neither the Company nor its domestic Subsidiaries have any
obligations for retiree health and life benefits under any Compensation and
Benefit Plan, except as set forth in the Company Disclosure Letter.  For a
minimum of the past ten years any such plan has always provided that the
Company or its domestic Subsidiaries may amend or terminate any such plan at
any time without incurring any material liability thereunder.

            (vii)   Except as disclosed in the Company Reports prior to the
date hereof or as specifically contemplated by this Agreement or as set forth
in Section 6.1(h) of the Company Disclosure Letter, the consummation of the
Merger and the other transactions contemplated by this Agreement will not (x)
entitle any employees of the Company or its Subsidiaries to severance pay, or
(y) accelerate the time of payment or vesting or trigger any payment of
compensation or benefits under, increase the amount payable or trigger any
other material obligation pursuant to, any of the Compensation or Benefit
Plans.

            (viii)  All Compensation and Benefit Plans covering current or
former non-U.S. employees or former employees of the Company and its
Subsidiaries comply in all material respects with applicable local law.  The
Company and its Subsidiaries have no material unfunded liabilities with respect
to any Pension Plan that covers such non-US employees.

            (i)     Compliance with Laws.  Except as set forth in the Company
Reports prior to the date hereof and except as disclosed in Section 6.1(i) of
the Company Disclosure Letter, the businesses of each of the Company and its
Subsidiaries have not been, and are not being, conducted in violation of any
law, ordinance, regulation, judgment, order, decree, arbitration award, license
or permit of any Governmental Entity (collectively, "Laws") with such
exceptions as would not likely have a Company Material Adverse Effect.  Except
as set forth in the Company Reports prior to the date hereof and except as
disclosed in Section 6.1(i) of the Company Disclosure Letter, the Company is
not aware of any material investigation or review by any Governmental Entity
with respect to the Company or any of its Subsidiaries nor has any Governmental
Entity indicated to the Company an intention to conduct the same.  No change is
required in the Company's or any of its Subsidiaries' processes, properties or
procedures in connection with any such Laws, and the Company has not received
any notice or communication of any noncompliance with any such Laws that has
not been cured as of the date hereof with such



                                      20
<PAGE>   25

exceptions as would not likely have a Company Material Adverse Effect.

            (j)     Takeover Statutes.  No supermajority vote is required under
any "fair price," "moratorium," "control share acquisition" or similar
antitakeover statute or regulation (each, a "Takeover Statute") in connection
with the Amended Offer, the Merger or the transactions contemplated hereby.
The Board has taken all appropriate and necessary action such that the
provisions of Section 203 of the DGCL will not apply to any of the transactions
contemplated by this Agreement.

            (k)     Voting Requirements; Company Articles.  (i) The affirmative
vote of the holders of a majority of the outstanding stock entitled to vote is
the only vote of the holders of any class or series of the Company's capital
stock or of any Voting Debt of the Company necessary to approve this Agreement
and the transactions contemplated by this Agreement (each outstanding Share
being entitled to 1 vote and each outstanding Convertible Preferred Share being
entitled to 1.5 votes) (the "Company Requisite Vote").

            (ii)    The Board of Directors of the Company has recommended the
Merger in accordance with Article Tenth of the Company Charter.

            (iii)   At least a majority of the Continuing Directors (as defined

its Subsidiaries have complied with all applicable Environmental Laws; (ii) the
properties presently or formerly owned or operated by the Company or its
Subsidiaries (including soil, groundwater or surface features and buildings or
structures thereon) (the "Properties") do not contain any Hazardous Substances
(as defined below) other than as permitted under applicable Environmental Law,
do not, and have not, contained any underground storage tanks; (iii) neither
the Company nor any of its Subsidiaries has received any claims, notices,
demand letters or requests for information alleging that the Company may be in
violation of, or liable under, any Environmental Law and none of the Company,
its Subsidiaries or the Properties are subject to any agreement, order or



                                      21
<PAGE>   26

decree involving liability under any Environmental Law; (iv) no Hazardous
Substance has been disposed of or released on any of the Properties; (v) the
Company and Subsidiaries are not subject to liability for any off-site disposal
or contamination; and (vi) there are no other circumstances involving the
Company or its Subsidiaries that could be expected to result in any claims,
liability, costs or losses or any restrictions on the ownership, use, or
transfer of any Property pursuant to any Environmental Law.

            "Environmental Law" means any law, regulation, order, decree,
opinion or agency requirement relating to pollution, contamination, wastes,
hazardous materials or the protection of the environment, human health or
safety and "Hazardous Substance" means any waste, mixture or matter containing

Adverse Effect, (a) the Company and its Subsidiaries have timely filed all Tax

Taxes for all periods heretofore ended, taking into account any extension of
time to file granted to or obtained on behalf of the Company and its

Subsidiaries that are or will become due or payable with respect to periods

reasonable best efforts to promptly inform the individuals or entities referred
to in the first sentence of this Section 7.2 of the obligations undertaken in
this Section 7.2.  The Company agrees that it will notify Praxair immediately
if (i) any such inquiries, proposals or offers are received by, any such
information is requested from, or any such negotiations or discussions are
sought to be initiated or continued with it or its Subsidiaries or (ii) the
Company determines that it is legally required for the discharge by the Board
of its fiduciary duties as advised by outside counsel to deliver such
information or to enter into such negotiations or discussions.  The Company
also agrees that it will promptly request each Person that has heretofore
executed any confidentiality agreement in connection with the consideration of
an Acquisition Proposal with respect to the Company or any of its Subsidiaries
or any of their businesses to return all confidential information heretofore
furnished to such Person by or on behalf of it or any of its Subsidiaries.

            7.3.    Stockholders Meeting.  The Company, acting through the
Board, will take, in accordance with applicable law, the Company Charter and
the Company's by-laws, all action necessary to duly call, give notice of,
convene and hold a special meeting of stockholders (the "Special Meeting") as
soon as practicable after the purchase of Shares by Purchaser pursuant to the
Amended Offer for the purpose of considering and taking action upon the Merger
and this Agreement and such other matters as may be necessary to consummate the
transactions contemplated by this Agreement.



                                      29

Subject to the fiduciary obligations of the Board under applicable law as
advised by outside counsel, the Board shall recommend approval of the Merger
and the adoption of this Agreement.  At any meeting of the Company's
stockholders, Praxair will cause the Shares acquired in the Amended Offer, and
any additional Shares owned by it or its affiliates, to be voted in favor of
this Agreement and the Merger.

            7.4.    Filings; Other Actions; Notification.  (a)  The Company,
acting through its Board, in consultation with Praxair, shall (i) prepare and,
following consummation of the Amended Offer, file with the Commission a
preliminary proxy statement (or, if applicable, a preliminary information
statement) relating to the matters to be considered at the Special Meeting
pursuant to this Agreement and use its reasonable best efforts (x) to obtain
and furnish the information required to be included in the Proxy Statement (as
hereinafter defined) and, after consultation with Praxair, to respond promptly
to any comments made by the Commission with respect to the preliminary proxy
statement (or, if applicable, a preliminary information statement) and to cause
a definitive proxy statement (or, if applicable, a definitive information
statement) (the "Proxy Statement") to be mailed to its stockholders and (y)
subject to the fiduciary obligations of the Board of Directors of the Company
under applicable law as advised by outside counsel, to obtain the necessary
approvals of the Merger, this Agreement and such other matters as may be
necessary to consummate the transactions contemplated hereby by its
stockholders; and

            (ii)    subject to the fiduciary obligations of the Board under
applicable law as advised by outside counsel, include in the Proxy Statement
the recommendation of the Board that stockholders of the Company vote in favor
of the approval of the Merger and the adoption of this Agreement.

            (b)     The Company and Praxair each shall cooperate with each
other and use (and cause their respective Subsidiaries to use) their respective
best efforts to prepare and file as promptly as practicable all documentation
to effect all necessary applications, notices, petitions, filings and other
documents and to obtain as promptly as practicable all permits, consents,
approvals and authorizations necessary or advisable to be obtained from any
third party and/or any Governmental Entity in connection with the Merger and to
consummate the other transactions contemplated by this Agreement.  Subject to
applicable laws relating to the exchange of information, Praxair and the
Company shall have the right to review in advance, and to



                                      30

<PAGE>   35

the extent practicable each will consult the other on, all the information
relating to Praxair or the Company, as the case may be, and any of their
respective Subsidiaries, that appear in any filing made with, or written
materials submitted to, any third party and/or any Governmental Entity in
connection with the Merger and the other transactions contemplated by this
Agreement.  In exercising the foregoing right, each of the Company and Praxair
shall act reasonably and as promptly as practicable.

            (c)     The Company and Praxair each shall, upon request by the
other and subject to applicable laws relating to the exchange of information,
furnish the other with all information concerning itself, its Subsidiaries,
directors, officers and stockholders and such other matters as may be
reasonably necessary or advisable in connection with the Proxy Statement or any
other statement, filing, notice or application made by or on behalf of Praxair,
the Company or any of their respective Subsidiaries to any third party and/or
any Governmental Entity in connection with the Merger and the transactions
contemplated by this Agreement.  Praxair agrees that confidential information
obtained by it pursuant hereto or pursuant to the Confidentiality Agreement
dated December 5, 1995 has been and shall be treated in accordance with the
provisions of such Confidentiality Agreement.

            (d)     The Company and Praxair each shall keep the other apprised
of the status of matters relating to completion of the transactions
contemplated hereby, including promptly furnishing the other with copies of
notice or other communications received by Praxair or the Company, as the case
may be, or any of its Subsidiaries, from any third party and/or any
Governmental Entity with respect to the Merger and the other transactions
contemplated by this Agreement.  The Company and Praxair each shall give prompt
notice to the other of any change that is reasonably likely to result in a
Company Material Adverse Effect or Praxair Material Adverse Effect,
respectively.

            (e)     Without limiting the generality of the undertakings
pursuant to this Section 7.4, the Company and Praxair each agree to take or
cause to be taken the following actions:  (i) provide promptly to any and all
federal, state, local or foreign court or Government Entity with jurisdiction
over enforcement of any applicable antitrust laws ("Government Antitrust
Entity") information and documents requested by such Government Antitrust
Entity or necessary, proper or advisable to permit consummation of the Merger
and the transactions contemplated by this Agreement and (ii) take promptly, in
the event that any



                                      31
<PAGE>   36

permanent or preliminary injunction or temporary restraining order, hold
separate order or other order is entered or sought in any proceeding that would
make consummation of the Merger or the Amended Offer in accordance with the
terms of this Agreement unlawful or that would prevent or delay consummation of
the Merger or the other transactions contemplated by this Agreement, any and
all steps (including the appeal thereof or the posting of a bond and including
the making of any divestiture; provided, that, the making of any such
divestitures with respect to assets in the United States does not relate to
assets generating more than $200,000,000 in revenues per annum in the
aggregate) necessary to vacate, modify or suspend or avoid such injunction or
order so as to permit such consummation of the Amended Offer no later than the
60th business day after the date of the Amended Offer.

            7.5.    Access.  Upon reasonable notice, and except as may
otherwise be required by applicable law, the Company shall (and shall cause its
Subsidiaries to) afford Praxair's officers, employees, counsel, accountants and
other authorized representatives ("Representatives") access, during normal
business hours throughout the period prior to the Effective Time, to its
properties, books, contracts and records and, during such period, shall (and
shall cause its Subsidiaries to) furnish promptly to the other all information
concerning its business, properties and personnel as may reasonably be
requested; provided that, no investigation pursuant to this Section 7.5 shall
affect or be deemed to modify any representation or warranty made by the
Company, Praxair or Purchaser; and provided, further, that, the foregoing shall
not require the Company to permit any inspection, or to disclose any
information, that in the reasonable judgment of the Company would result in the
disclosure of any trade secrets of third parties or violate any of its
obligations with respect to confidentiality if the Company shall have used
reasonable best efforts to obtain the consent of such third party to such
inspection or disclosure and provided, further, that Praxair shall use its
reasonable best efforts to promptly notify the Company if it discovers any
information that might indicate that any representation or warranty by the
Company is incorrect, incomplete or otherwise deficient.  All requests for
information made pursuant to this Section 7.5 shall be directed to an executive
officer of the Company or such Person as may be designated by its officers.

            7.6.    Publicity.  The initial press release shall be a joint
press release and thereafter the Company and Praxair each shall use reasonable
best efforts to consult with each other prior to issuing any press releases or



                                      32
<PAGE>   37

otherwise making public announcements with respect to the Merger and the other
transactions contemplated by this Agreement and prior to making any filings
with any third party and/or any Governmental Entity (including any national
securities exchange) with respect thereto.

            7.7.    Benefits.

            (a)     Stock Options.  The Company shall take all actions
necessary to provide that, immediately prior to the consummation of the Amended
Offer, each Company Option which is not then exercisable will be exercisable in
full and each Company Option (and each related stock appreciation right)
outstanding prior to the Effective Time pursuant to any of the Stock Plans,
whether or not then exercisable, shall be canceled and only entitle the holder
thereof, upon surrender thereof, to receive an amount in cash equal to the
difference between the Merger Consideration and the exercise price per Share of
such Company Option multiplied by the number of Shares previously subject to
such Company Option (such payment to be net of applicable withholding taxes).

            (b)     Except as set forth in Section 7.7(b) of the Company
Disclosure Letter and except as provided herein or as otherwise agreed to by
the parties and to the extent permitted by the Stock Plans, (i) the Stock Plans
shall terminate immediately following the purchase of Shares pursuant to the
Amended Offer and the provisions in any other plan, program or arrangement,
providing for the issuance or grant of any other interest in respect of the
capital stock of the Company or any of its Subsidiaries shall be deleted as of
the Effective Time and (ii) the Company shall use all reasonable efforts to
ensure that following the Effective Time no holder of Company Options or any
participant in the Stock Plans or any other plans, programs or arrangements
shall have any right thereunder to acquire any equity securities of the
Company, the Surviving Corporation or any subsidiary thereof.

            (c)     Employee Benefits.  Praxair agrees that, during the period
commencing on consummation of the Amended Offer and ending on the first
anniversary thereof, the employees of the Company and its Subsidiaries and
former employees of the Company and its Subsidiaries, other than employees
covered by collective bargaining agreements, will continue to be provided with
benefits under employee benefit plans with a value which is not less in the
aggregate than that currently provided by the Company and its Subsidiaries to
such employees.  In so providing any such benefits or plans, for purposes of
participation and vesting Purchaser and Praxair agree to give employees of the
Company and its



                                      33
<PAGE>   38

Subsidiaries service credit for all periods of employment with any such entity
prior to the Effective Time for purposes of any such plans or benefits so
provided.  Praxair will, and will cause the Surviving Corporation to, honor all
employee (or former employee) benefit obligations and contractual rights
existing as of the Effective Time and, to the extent set forth in the Company
Reports or otherwise specifically disclosed in the Company Disclosure Letter,
all employment or severance agreements, plans or policies of the Company and
its Subsidiaries in accordance with their terms.  Purchaser acknowledge and
agree that consummation of the Amended Offer constitutes a "Change in Control"
with respect to those persons listed, and pursuant to the agreements and plans
set forth in, Section 7.7(c) of the Company Disclosure Letter.

            7.8.    Expenses.  The Surviving Corporation shall pay all charges
and expenses, including those of the Paying Agent, in connection with the
transactions contemplated in Article V, and Praxair shall reimburse the
Surviving Corporation for such charges and expenses.  Whether or not the Merger
is consummated, all costs and expenses incurred in connection with this
Agreement and the Merger and the other transactions contemplated by this
Agreement shall be paid by the party incurring such expense, except as may be
permitted by Section 9.5 hereof and except that expenses incurred in connection
with printing and mailing the Proxy Statement shall be shared equally by
Praxair and the Company.

            7.9.    Indemnification; Directors' and Officers' Insurance.  (a)
From and after the Effective Time, Praxair agrees that it will indemnify and
hold harmless each present and former director, officer and employee of the
Company, determined as of the Effective Time (the "Indemnified Parties"),
against any costs or expenses (including reasonable attorneys' fees),
judgments, fines, losses, claims, damages or liabilities (collectively,
"Costs") incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative,
arising out of matters existing or occurring at or prior to the Effective Time,
whether asserted or claimed prior to, at or after the Effective Time, to the
fullest extent that the Company would have been permitted under Delaware law
and the Company Charter or the Company's by-laws in effect on the date hereof
to indemnify such Person (and Praxair shall also advance expenses as incurred
to the fullest extent permitted under applicable law; provided, that, the
Person to whom expenses are advanced provides an undertaking to repay such
advances if it is ultimately determined that such Person is not entitled to
indemnification); and provided, further, that, any



                                      34
<PAGE>   39

determination required to be made with respect to whether an officer's or
director's conduct complies with the standards set forth under Delaware law and
the Company Charter and the Company's by-laws shall be made by counsel selected
by the Surviving Corporation.  Purchaser agrees that all rights to
indemnification in favor of any present or former employee, agent, director or
officer of the Company and its subsidiaries (the "Indemnified Parties") as
provided in their respective charters or by-laws, in an agreement between an
Indemnified Party and the Company or any of its subsidiaries, or otherwise in
effect on the date hereof shall survive the Merger and shall continue in full
force and effect for a period of not less than five years from the Effective
Time; provided that in the event any claim or claims are asserted or made
within such five-year period, all rights to indemnification in respect of any
such claim or claims shall continue until final disposition of any and all such
claims.

            (b)     Any Indemnified Party wishing to claim indemnification
under paragraph (a) of this Section 7.9, upon learning of any such claim,
action, suit, proceeding or investigation, shall promptly notify Praxair
thereof.  An Indemnified Party may select counsel to represent him or her in
connection with any of the foregoing, which counsel shall be reasonably
acceptable to Purchaser, and Purchaser and the Company will cooperate in the
defense of any such matter; provided, however, that neither Purchaser nor the
Company shall be liable for any settlement effected without its written consent
and provided, further, that neither Purchaser nor the Company shall be
obligated to pay the fees and disbursements of more than one counsel for all
Indemnified Parties in any single matter except to the extent that, in the
opinion of counsel for the Indemnified Parties, two or more of such Indemnified
Parties have conflicting interests in the outcome of such matter.  Praxair
shall not have any obligation hereunder to any Indemnified Party if and when a
court of competent jurisdiction shall ultimately determine, and such
determination shall have become final, that the indemnification of such
Indemnified Party in the manner contemplated hereby is prohibited by applicable
law.

            (c)     Praxair agrees that it shall use all reasonable efforts to
maintain the Company's existing officers, and directors, liability insurance
policy and employee benefit plan fiduciary liability insurance ("D&0
Insurance") for a period of not less than five years from and after the
Effective Time; provided, (i) that Praxair may substitute therefor policies of
substantially similar coverage and amounts containing terms no less
advantageous



                                      35
<PAGE>   40

to the Indemnified Parties and (ii) if the existing D&O Insurance expires or is
canceled during such period, Praxair will use reasonable efforts to obtain
substantially similar D&O Insurance to the extent available; provided, further,
that, notwithstanding clauses (i) and (ii) of this subsection 7.9(c), in the
event that the aggregate annual premiums for D&O Insurance at any time during
such five year period shall exceed 175% of the per annum rate of premium
currently paid (the "Base Rate") by Company and its Subsidiaries for such D&O
Insurance on the date of this Agreement, then Praxair shall only be obligated
to provide the maximum coverage that shall then be available at an annual
premium equal to 175% of the Base Rate.

            (d)     If the Surviving Corporation or any of its successors or
assigns (i) shall consolidate with or merge into any other corporation or
entity and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or (ii) shall transfer all or substantially all of
its properties and assets to any individual, corporation or other entity, then
and in each such case, proper provisions shall be made so that the successors
and assigns of the Surviving Corporation shall assume all of the obligations
set forth in the last two sentences of Section 7.7(c) and this Section 7.9.

            (e)     The provisions of this Section 7.9 are intended to be for
the benefit of, and shall be enforceable by, each of the Indemnified Parties,
their heirs and their representatives.

            7.10.   Other Actions by the Company and Praxair.

            (a)     Rights.  The Company, acting through its Board, shall take
all necessary action (and shall notify Praxair of any such actions taken) prior
to the Expiration Date including, without limitation, supplementing or amending
the Rights Agreement to ensure that, so long as this Agreement has not been
terminated, the Amended Offer is a "Permitted Tender Offer" (as defined in the
Rights Agreement), (it being understood that the Company shall amend the
definition of "Permitted Tender Offer" in the Rights Agreement), no
"Distribution Date" (as defined in the Rights Agreement) will occur and Section
11.1(b) of the Rights Agreement will not be triggered, in each case as a result
of the announcement, commencement or consummation of the Amended Offer or the
execution or delivery of this Agreement with the effect that none of such
events will trigger the exercisability of the Rights or the separation of the
Rights from the certificates to which they are attached.  So long as this
Agreement has not been



                                      36
<PAGE>   41

terminated, the Board shall also take all further action (in addition to that
referred to above) requested in writing by Praxair or Purchaser (including
redeeming the Rights immediately prior to the Effective Time or amending the
Rights Agreement) in order to render the Rights inapplicable to the Merger and
the other transactions contemplated by this Agreement.  Except as provided
above with respect to the Merger and the other transactions by Praxair or
Purchaser, the Board shall not (i) amend the Rights Agreement or (ii) take any
action with respect to, or make any determination under, the Rights Agreement,
including a redemption of the Rights or any action to facilitate an Acquisition
Proposal, provided, however, that nothing herein shall be deemed to preclude
the Company from taking any action with respect to the Rights Agreement
(including any modification or amendment thereto or waiver thereof) as it
applies to any third party other than Praxair and the Purchaser to the extent
required for the Board of Directors of the Company to comply with its fiduciary
obligations under applicable law, as advised in writing by outside counsel to
the Company.  The Company will promptly furnish to Praxair and Purchaser a
complete and correct copy of the Rights Agreement, as so amended.

            (b)     Takeover Statute.  If any Takeover Statute is or may become
applicable to the Initial Offer, the Amended Offer, the Merger or any other
transaction contemplated by this Agreement, the Company and the Board shall
grant such approvals and take such actions as are necessary so that such
transactions may be consummated as promptly as practicable on the terms
contemplated by this Agreement or by the Merger and otherwise act to eliminate
or minimize the effects of such statute or regulation on such transactions.

            (c)     Termination of Litigation.  The parties hereto shall
immediately dismiss, with each party bearing its own costs and litigation
expenses, all proceedings pending between themselves and their affiliates and
each shall thereafter sign and deliver such further papers as may be necessary
in connection with such dismissals.

            7.11.   Notification of Certain Matters.  Each of Praxair and the
Company shall give prompt notice to the other party of (i) the occurrence, or
non-occurrence, of any event the occurrence, or non-occurrence, of which would
be likely to cause either (A) any representation or warranty contained in this
Agreement to be untrue or inaccurate in any material respect at any time from
the date hereof to the acceptance for payment of Shares pursuant to the Amended
Offer, (B) any condition set forth in Annex A to be



                                      37
<PAGE>   42

unsatisfied in any material respect at any time from the date hereof to the
date the Purchaser purchases Shares pursuant to the Amended Offer or (C) any
condition set forth in Article VIII hereof to be unsatisfied in any material
respect at any time from the date hereof to the Effective Time, and (ii) any
material failure of Praxair or the Company, as the case may be, or any officer,
director, employee or agent thereof, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder;
provided, however, that the delivery of any notice pursuant to this Section
7.11 shall not limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

which is in effect and prohibits consummation of the transactions contemplated
by this Agreement (collectively, an "Order");



                                      38

<PAGE>   45

Company's stockholders than the terms of the Amended Offer and the Merger, and

required for the discharge of its fiduciary duties, (A) not to continue to
recommend that holders of Shares accept the Amended Offer and tender their
Shares pursuant to the Amended Offer, and (B) to accept such Acquisition
Proposal; provided, however, that the Company shall not be permitted to
terminate this Agreement pursuant to this Section 9.4(iii) unless it has
provided Praxair and Purchaser with two business days prior written notice of
this intent to so terminate this Agreement together with a detailed summary of
the terms and conditions (including proposed financing, if any) of such
Acquisition Proposal; provided, further, that Purchaser shall receive the fee
set forth in Section 9.5(b) immediately prior to any termination pursuant to
this Section 9.4(iii) by wire transfer in same day funds.

          9.5.  Effect of Termination and Abandonment.      (a) In the event of
termination of this Agreement and abandonment of the Merger pursuant to this
Article IX, no party hereto (or any of its directors or officers) shall have
any liability or further obligation to any other party to this Agreement,
except as provided in Section 9.5(b) below and Section 10.2 and except that
nothing herein will relieve any party from liability for any breach of this
Agreement.  Nothing herein shall limit the ability of the Company upon
termination of this Agreement in accordance with its terms to make the Rights
(or any similar rights issued under any new rights agreement entered into by
the Company) applicable to any proposal or offer made by Praxair or any
affiliate thereof.

            (b) If (x) (i) the Amended Offer shall have remained open for a
minimum of at least 10 business days, (ii) after the date hereof any
corporation, partnership, person, other entity or group (as defined in Section
13(d)(3) of the Exchange Act) other than Praxair or Purchaser or any of their
respective subsidiaries or affiliates (collectively, an "Acquiring Person")
shall have become the beneficial owner of 10% or more of the outstanding
Shares, and (iii) the Minimum Tender Condition (as defined in Annex A) shall
not have been satisfied and the Amended Offer is terminated in accordance with
this Agreement without the purchase of any Shares thereunder, (y) Praxair shall
have terminated this Agreement pursuant to Section 9.3(y) hereof or (z) the
Company shall have terminated this Agreement pursuant to Section 9.4(iii)
hereof, then the Company, if requested by Praxair, shall promptly, but in no
event later than two days after the date of such request, pay Praxair a fee of
$43,500,000 which



                                      41

amount shall be payable in same day funds.  The Company acknowledges that the
agreements contained in this Section 9.5(b) are an integral part of the
transactions contemplated in this Agreement, and that, without these
agreements, Praxair and Purchaser would not enter into this Agreement;
accordingly, if the Company fails to promptly pay the amount due pursuant to
this Section 9.5(b), and, in order to obtain such payment, Praxair or Purchaser
commences a suit which results in a judgment against the Company for the fee
set forth in this paragraph (b), the Company shall pay to Praxair or Purchaser
its costs and expenses (including attorneys' fees) in connection with such
suit, together with interest on the amount of the fee at the prime rate of
Morgan Guaranty Trust Company of New York on the date such payment was required
to be made.

                                    ANNEX A



            Notwithstanding any other provision of the Initial Offer or the
Amended Offer and provided that Purchaser shall not be obligated to accept for
payment any Shares until expiration or termination of all applicable waiting
periods under the HSR Act and Investment Canada Act, Purchaser shall not be
required to accept for payment or pay for, or may delay the acceptance for
payment of or payment for, any tendered Shares, or subject to the terms of the
Merger Agreement may, in its sole discretion, terminate or amend the Amended
Offer as to any Shares not then paid for if:

    (i)     there is not tendered and not withdrawn prior to the Expiration
            Date at least that number of Shares (the "Minimum Number of
            Shares") that would represent a majority of all outstanding Shares
            on a fully diluted basis on the date of purchase (the "Minimum
            Tender Condition").  For purposes of the Amended Offer, "on a fully
            diluted basis" means, as of any date, the number of Shares
            outstanding together with Shares that the Company is required to
            issue pursuant to obligations outstanding at that date under
            convertible securities, stock options or otherwise.

    (ii)    Purchaser is not, in its reasonable discretion, satisfied that the
            Rights will not become exercisable upon consummation of the Amended
            Offer;

    (iii)   Purchaser is not satisfied, in its reasonable discretion, that
            after consummation of the Amended Offer, the restrictions contained
            in Section 203 of the DGCL will not apply to the Merger;

    (iv)    Purchaser is not satisfied, in its reasonable discretion, that no
            supermajority vote will be required by Article Tenth or Article
            Fifteenth of the Company Charter to approve the Merger or that
            after consummation of the Amended Offer, Purchaser will otherwise
            possess sufficient voting power to effect the Merger without the
            affirmative vote of any person other than Purchaser;

    (v)     On or after December 21, 1995 and at or before the time of payment
            for any of such Shares any of the following shall occur:



                                      A-1
<PAGE>   52

            (a)         there shall have occurred and be continuing (i) any
                        general suspension of, or limitation on prices for,
                        trading in securities on the NYSE or in the over-
                        the-counter market, (ii) a declaration of a banking
                        moratorium or any suspension of payments in respect of
                        banks in the United States, (iii) a commencement or
                        escalation of a war, armed hostilities or other
                        international or national calamity directly or
                        indirectly involving the United States (other than the
                        current action in Bosnia), (iv) any limitation (whether
                        or not mandatory) by any Governmental Entity, on the
                        extension of credit by banks or other lending
                        institutions, (v) any significant adverse change in
                        interest rates or major stock indices in the United
                        States or abroad, including, without limitation, a
                        decline of at least 15% in either the Dow Jones Average
                        of Industrial Stocks or the Standard & Poor's 500 index
                        from that existing at the close of business on December
                        21, 1995, (vi) a currency moratorium on or a suspension
                        of, the currency exchange markets in the United States,
                        or (vii) in the case of any of the foregoing existing
                        at the date hereof, a material acceleration or
                        worsening thereof;

            (b)         there shall be instituted or pending any action,
                        litigation, proceeding, investigation or other
                        application (hereinafter, an "Action") by any
                        Governmental Entity:  (i) challenging the acquisition
                        by Praxair, Purchaser or any other wholly-owned
                        subsidiary of Praxair of Shares, seeking to restrain or
                        prohibit the consummation of the transactions

                        Merger, seeking to obtain any material damages or
                        otherwise directly or indirectly relating to the
                        transactions contemplated by the Agreement, the
                        Amended Offer or the Merger or other subsequent
                        business combination; (ii) seeking to prohibit, or
                        impose any



                                     A-2
<PAGE>   53

                        material limitations on, Praxair's, Purchaser's or any
                        other wholly-owned subsidiary of Praxair's ownership or
                        operation of all or any portion of their or the
                        Company's business or assets (including the business or
                        assets of their respective affiliates and
                        subsidiaries), or to compel Praxair or Purchaser to

                        Praxair's or Purchaser's or the Company's business or
                        assets (including the business or assets of their
                        respective affiliates and subsidiaries) as a result
                        of the transactions contemplated by the Agreement, the
                        Amended Offer or the Merger or other subsequent
                        business combination; (iii) seeking to make the
                        acceptance for payment, purchase of, or payment for,
                        some or all of the Shares illegal or render Purchaser
                        unable to, or result in a delay in, or restrict, the
                        ability of Purchaser to accept for payment, purchase or
                        pay for some or all of the Shares; (iv) seeking to
                        impose material limitations on the ability of Praxair
                        or Purchaser effectively to acquire or hold or to

                        including, without limitation, the right to vote the
                        Shares purchased by them on an equal basis with all
                        other Shares on all matters properly presented to the
                        stockholders of the Company; or (v) that, in any event,
                        in the reasonable judgment of Purchaser, is reasonably
                        likely to have a Company Material Adverse Effect (other
                        than litigation disclosed in the Company Disclosure
                        Letter);

            (c)         any statute, rule, regulation, order, judgment or
                        injunction shall be enacted or entered with respect to
                        the Amended Offer or the Merger, or any other action
                        shall have been taken by any court or other
                        Governmental Entity other than the application to the
                        Amended Offer or the Merger of waiting periods under
                        the HSR Act that, in the reasonable judgment of Praxair

                        be expected to

which, in the reasonable judgment of Purchaser in any such case, and
regardless of the circumstances (including, without limitation, any action or
inaction by Purchaser, Praxair or any other affiliate of Praxair) giving rise
to any such condition, makes it

inadvisable to proceed with the Amended Offer or with acceptance for
payment or payment for Shares.

      The foregoing conditions are for the sole benefit of Praxair and
Purchaser and their respective affiliates and may be asserted by Praxair and
Purchaser regardless of the circumstances (including, without limitation, any
action or inaction by Praxair, Purchaser or any of their respective affiliates)
giving rise to any such condition other than the Minimum Tender Condition or
may be waived by Praxair or Purchaser in whole or in part at any time and from
time to time in its sole discretion.  The failure by Praxair or Purchaser at
any time to exercise any of the foregoing rights will not be deemed a waiver of
any such right, the waiver of any such right with respect to particular facts
and circumstances will not be deemed a waiver with respect to any other facts
and circumstances and each such right will be deemed an ongoing right that may
be asserted at any time and from time to time.

                      [CBI INDUSTRIES, INC. LETTERHEAD]
 
                                                               December 28, 1995
 
To Our Stockholders:
 
     CBI Industries, Inc. has entered into a merger agreement with Praxair, Inc.
which provides for a wholly owned subsidiary of Praxair to amend its existing
cash tender offer to increase the price offered for all outstanding common
shares of CBI from $32.00 per share to $33.00 per share. The Praxair tender
offer will be followed by a merger of the Praxair subsidiary with CBI. In the
merger, each CBI share which is not purchased in the tender offer (other than
shares owned by Praxair and its subsidiaries and shares as to which dissenters'
rights are perfected) will be converted into the right to receive $33.00 in
cash.
 
     THE BOARD OF DIRECTORS OF CBI HAS UNANIMOUSLY APPROVED THE TRANSACTION WITH
PRAXAIR, HAS DETERMINED THAT THE AMENDED OFFER AND THE MERGER ARE FAIR TO AND IN
THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND RECOMMENDS THAT
STOCKHOLDERS ACCEPT THE $33.00 AMENDED OFFER AND TENDER THEIR SHARES. The
amended offer is scheduled to expire at midnight, New York City time, on
Thursday, January 11, 1996.
 
     Enclosed are Praxair's Supplement dated December 28, 1995 to its Offer to
Purchase dated November 3, 1995, and a revised Letter of Transmittal. These
documents set forth the amended terms and conditions of the Praxair tender offer
and contain other important information relating to the tender offer and the
merger. These documents also provide instructions as to how to tender your CBI
shares. Also attached is a copy of an amendment to CBI's Schedule 14D-9, as
filed with the Securities and Exchange Commission. The attached Schedule 14D-9
describes in more detail the reasons for your Board's decision. Among other
things, the Board considered the opinions of Lehman Brothers Inc. and Merrill
Lynch & Co., its financial advisors, that, as of such date, the consideration to
be offered to CBI stockholders pursuant to the amended tender offer and the
merger is fair to such stockholders from a financial point of view. We urge you
to read all of these materials carefully; including the text of such opinions
attached as Annexes to the Schedule 14D-9.
 
     Your Board of Directors, the management and employees of CBI thank you
sincerely for your loyal support.
 
                  On behalf of the Board of Directors,
 
                                            /s/  John E. Jones

              FORM OF LETTER TO RESTRICTED STOCK PLAN PARTICIPANTS


Dear Restricted Stock Plan Participant:

         As you are undoubtedly aware, on December 22, 1995, CBI Industries,
Inc. (the "Company") and Praxair, Inc. ("Praxair") announced that they had
entered into a merger agreement pursuant to which Praxair is increasing the
price offered in its tender offer to $33 per share and each share not tendered
will be converted into the right to receive $33 per share in a second step
merger.

         Under the terms of the Company's restricted stock plans, shares you
hold which are still subject to restrictions would be forfeited if you
attempted to tender them into the Praxair tender offer.  Accordingly, those
shares that are still subject to restriction should not be tendered.

         However, pursuant to the merger agreement, immediately following
Praxair's purchase of shares in its tender offer and assuming Praxair buys 10%
or more of the Company's shares in the tender offer, the restricted stock plans
will terminate and the restrictions on those shares subject to restriction will
lapse.  Thereafter, subject to federal securities laws restricting the trading
in shares by insiders in possession of material nonpublic information, you will
be free to sell those shares in the market.  If you do not dispose of those
shares or exercise appraisal rights, such shares will be converted in the
merger into the right to receive $33 per share in cash. When the restrictions
lapse, you will have 1996 taxable income unless you previously made an election
under Code Section 83(b) to recognize income at the time of the award.  For
employees on the U.S. payroll, this income will be subject to federal,
applicable state and FICA tax withholding.

         The Compensation Committee of the Board of Directors has resolved that
immediately prior to the termination of the 1994 Restricted Stock Award Plan
pursuant to the terms of the merger agreement, awards not previously certified
will be made as follows:

1.       94.1% of each award based on 1995 performance will be deemed earned
         and will be paid in cash; and

2.       all awards adjustable by 1996 and 1997 performance will be treated as
         if earned and will be paid in cash.
<PAGE>   2
In each case it is anticipated that the amount of cash you receive will be
determined based upon the price paid pursuant to the amended Praxair tender
offer and, if no 83(b) election has been made, will constitute 1996 taxable
income subject to withholding as described above.

         Please do not hesitate to call me if you have any questions with
regard to the foregoing.


                                        Very truly yours,
