                                    AGREEMENT


     THIS AGREEMENT between CBI INDUSTRIES, INC., a Delaware corporation
("CBI"), and Calvin E. Willoughby, Jr. ("Executive"), dated this 3rd day of
October, 1989.


                                 WITNESSETH THAT


     WHEREAS, CBI wishes to attract and retain well-qualified executives and
both CBI and the Executive desire continuity of management in the event of any
Change in Control of CBI;

     NOW, THEREFORE, it is hereby agreed by and between the parties as follows:

     1.   Effective Date. The "Effective Date" of this Agreement shall be the 
date on which a Change in Control of CBI (as defined in Section 2) occurs.

     2.   Change in Control. The term "Change in Control" shall mean the
occurrence at any time of any of the following events:

     (a)  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 CBI.


   2


For purposes of this Agreement, the terms "Acquiring Person" and "Continuing
Directors" shall have the respective meanings ascribed to such terms in that
certain Rights Agreement dated March 4, 1986, between CBI and Morgan Guaranty
Trust Company of New York as rights agent, the relevant portions of which for
convenience of reference are reproduced as Exhibit I to this Agreement.

     3.   Employment. CBI hereby agrees that if the Executive continues as an
employee of CBI from the date of execution hereof until the Effective Date, CBI
shall continue the Executive in its employ for the period commencing on the
Effective Date and ending on the earlier to occur of the third anniversary of
such date or the 65th birthday of the Executive (the "Employment Period"), to
exercise such authority and perform such executive duties as are requested of
him by CBI, which authority and duties shall be commensurate with the authority
being exercised and duties being performed by the Executive immediately prior to
the Effective Date. The Executive shall perform such requested services at the
location where the Executive was employed immediately prior to the Effective
Date, except for required travel on CBI's business to an extent substantially
consistent with the Executive's business travel obligations prior to the
Effective Date. The Executive agrees that while an employee during the
Employment Period he shall, to the extent required, devote substantially


                                      -2-
   3
all of his business time to his executive duties as described herein and 
perform such duties faithfully and efficiently.

        4.  Compensation, Compensation Plans, Benefits.  During the Employment 
Period, the Executive shall be compensated as follows:

        (a)  He shall receive an annual salary (to be paid in equal biweekly 
installments) which is not less than his rate of annual salary in effect 
immediately prior to the Effective Date, increased on each January 1 within the 
remainder of the Employment Period by at least the greater of (i) the average 
annual percentage salary increase for the Executive during the period of three 
full calendar years immediately preceding the Effective Date, or (ii) the 
percentage increase in the Implicit Price Deflator for Gross National Product 
for the calendar year immediately preceding such January 1, as published by the 
United States Department of Commerce in its Survey of Current Business in 
December of each year, over such Implicit Price Deflator for the calendar year 
next preceding such year.

        (b)  He shall be awarded and receive bonus, restricted stock award, 
stock option, and other incentive compensation for each calendar year (or other 
applicable bonus or incentive compensation 




                                      -3-
   4
period) any part of which is included in the Employment Period, which in the 
aggregate shall not in value be a lesser percentage of his annual salary, as 
determined in subsection (a) above, for such calendar year (or period), than 
the aggregate bonus, restricted stock award, stock option, and other incentive 
compensation during the period of three full calendar years immediately 
preceding the Effective Date was of the Executive's aggregate base salary for 
such three year period.

        (c)  He shall be entitled to receive all employee benefits to the 
extent of the  greater of the employee benefits provided by CBI to executives 
with comparable duties or the employee benefits to which he was entitled 
immediately prior to the Effective Date.

        (d)  During any period that Executive is unable to perform the services 
for CBI specified in Section 3, whether as a result of total disability or as a 
result of a physical or mental disability that is not total or is not permanent 
and therefore is not a total disability, Executive shall continue to receive 
base salary at the rate in effect at the commencement of any such period, 
together with all other compensation and benefits that are payable under 
this Agreement.


                                     - 4 -
   5
        (e)  He shall be furnished at CBI's expense with an automobile, office, 
reasonable secretarial help, club memberships, reimbursement for reasonable 
entertainment expenses, and such other supplies, equipment, facilities, 
services and emoluments appertinent to his position to the extent of the 
greater of such emoluments provided by CBI to executives with comparable duties 
or the emoluments to which he was entitled immediately prior to the Effective 
Date.

        (f)  He shall be covered by directors and officers liability and 
indemnity insurance or equivalent protection arranged and funded by CBI, and by 
corporate indemnity protection, to the extent of the greatest level of 
protection afforded to such Executive under any and all policies of directors 
and officers liability and indemnity insurance, by-law provisions or any other 
arrangements or agreements, at any time within the period of three full 
calendar years immediately preceding the Effective Date.

        5.  Termination.  The term "Termination" shall mean the occurrence 
during the Employment Period of:

        (a)  termination by CBI of the employment of the Executive for any 
reason other than (i) death, (ii)


                                     - 5 -
   6


physical or mental incapacity which would entitle Executive to permanent
disability benefits under CBI's appropriate plans, or (iii) a willful and
material breach of this Agreement by the Executive which causes a direct and
substantial injury to CBI or to its business, which is not cured by Executive
within 30 days after receiving written notice of such breach and reasonable
directions for cure from CBI; or

        (b)  the resignation of the Executive from his employment upon 30 days
written notice to CBI at any time following (i) a significant change in the
nature or scope of the Executive's authorities or duties from those described in
Section 3, a reduction in total compensation from that provided in Section 4, or
the breach by CBI of any other provision of this Agreement, which change,
reduction or breach is not restored or cured by CBI within 30 days after
receiving written notice of such change, reduction or breach and reasonable
directions for restoration or cure from the Executive; or (ii) a reasonable
determination by the Executive that, as a result of the Change in Control and a
change in circumstances thereafter significantly affecting his position, he is
unable to exercise the authorities, powers, functions or duties attached to his
position as contemplated by Section 3.


                                   - 6 -
   7
        A Termination as contemplated by this Section 5, whether or not a
breach of this Agreement by CBI, shall entitle the Executive to Termination
benefits as provided by this Agreement. Nothing in this Agreement shall prevent
the Executive from voluntarily resigning from his Employment upon 90 days
written notice to CBI under circumstances which do not constitute Termination as
defined in this Section 5, and no such resignation shall be deemed a breach of
this Agreement by the Executive.

        6.  Termination Payment.  In the event of Termination of Executive 
during the Period of Employment, CBI shall pay to the Executive a lump sum
amount equal (without discount to present value) to the sum of the amounts
determined in accordance with subsections (a), (b), (c) and (d) below, and
provide the additional benefits described in subsections (w), (x), (y) and (z)
below:

               (a)  An amount equal to the aggregate salary which would have
          been paid to the Executive during the remainder of the Employment
          Period if he had received the base salary specified by Section 4(a)
          above, increased by assuming the salary increase on each January 1
          during the remainder of the Employment Period to be the greatest of 
          the average annual percentage salary increase or the percentage 
          increase in the Implicit Price Deflator, whichever is

                                      -7-
   8
applicable, as of any January 1 within three calendar years including or 
preceding the Termination date.

        (b)  Bonus and incentive compensation for any calendar year (or other 
applicable bonus or incentive compensation period) ending prior to the 
Termination date but not previously paid.

        (c)  An amount equal to the aggregate bonus and incentive compensation 
which would have been paid to the Executive during each calendar year (or other 
applicable bonus or incentive compensation period) any part of which is 
included in the remainder of the Employment Period if he had received bonus and 
incentive compensation for any such year (or period) in the minimum amount 
specified by Section 4(b) based on his increased salary determined under 
subsection (a) above; provided, however, that in the event any bonus year (or 
period) extends beyond the end of the Employment Period, bonus or other 
incentive compensation for such year (or period) shall be pro-rated in 
proportion to the number of days within and without the Employment Period.

        (d)  In the event any shares of CBI common stock (or other securities 
into which such shares may have



                                - 8 -
   9


     been converted) previously awarded to Executive under any restricted stock
     award Plans of CBI or separate agreements between Executive and CBI are
     forfeited by reason of such Termination, an amount in cash equal to the
     fair market value of such forfeited common stock (or other securities) as
     of the date of Termination. The rights afforded to Executive under this
     subsection (d) are without prejudice to any other rights Executive has to
     shares of CBI common stock (or other securities) under such plans or
     agreements or by reason of the action of the CBI Board of Directors
     heretofore taken in causing restrictions on such shares to be removed under
     certain circumstances including Termination of the Executive.

CBI shall also provide to the Executive:

          (w)  In addition to the benefits provided under any pension benefit
     plan, benefit restoration plan, profit sharing plan, or employee stock
     ownership plan (whether or not funded or qualified under the Internal
     Revenue Code) maintained by CBI ("Retirement Plans"), the difference (the
     "Benefit Enhancement") between such benefits and the benefits (the
     "Enhanced Benefits") that would have been provided under such Retirement
     Plans if Executive had remained in the employ of CBI throughout the
     Employment Period at the


                                       -9-


   10


     salary determined under subsection (a) above accruing additional age and
     service credits under such Retirement Plans accordingly. If after giving
     effect to such additional age and service credit Executive shall not have
     the necessary age or credited service at the end of the Employment Period
     to qualify under the CBI Pension Plan (the "Pension Plan") for an early
     retirement pension, the Enhanced Benefits under this subsection (w) shall
     nevertheless include an early retirement pension under the Pension Plan
     beginning upon Executive attaining age 55 or upon the date Executive would
     have attained 30 years of credited service had Executive remained
     continuously employed by CBI but for Termination (whichever occurs first)
     (the "Enhanced Early Retirement Pension"). The Enhanced Early Retirement
     Pension shall be payable to the Executive or to the spouse of the Executive
     (if applicable) commencing at the time Executive attains (or would have
     attained) age 55 or would have otherwise attained 30 years of credited
     service as provided aforesaid (whichever occurs first). The Enhanced Early
     Retirement Pension shall only be subject to reduction at the rate of four
     (4) percentum for each year by which the Executive's age is less than age
     65 or the Executive's credited service is less than 40 years, whichever
     produces the lesser


                                      -10-


   11


     reduction, pursuant to the first sentence of Section 5.2.3 of the Pension
     Plan (as in effect on the date hereof). If Executive shall die after the
     end of the Employment Period but before the date the Enhanced Early
     Retirement Pension is payable, the spouse of Executive shall be entitled to
     an enhanced survivor's pension under the Pension Plan as if Executive had
     died as an employee of CBI, giving effect to service through the date of
     Executive's death and Executive's earnings through the end of the
     Employment Period. Such Benefit Enhancement will be paid beginning on the
     date the Enhanced Benefits would have commenced and thereafter concurrently
     with the benefits actually provided under such Retirement Plans; except
     that if the Executive receives a distribution from any profit sharing or
     employee stock ownership plan before the Benefit Enhancement required by
     this subsection in respect of such Retirement Plan become determinable, the
     Benefit Enhancement in respect of such plan shall be paid as soon
     thereafter as such benefits become determinable. Nothing in this subsection
     (w) shall prevent the actual commencement of benefits under any Retirement
     Plan, and the Benefit Enhancements required by this subsection (w), before
     the end of the Employment Period to the extent required or permitted under
     the terms of the applicable Retirement Plan,


                                      -11-


   12


     giving effect to the additional age and service credit required by this
     subsection (w).

          (x)  Participation in or coverage by all other employee benefits,
     including, but not limited to, coverage under any health or medical benefit
     insurance, plans, or arrangements, supplemental survivors' benefit plans,
     or life insurance arrangements or programs, to the same extent to which he
     would have been entitled under all employee benefit plans, programs,
     arrangements or practices maintained by CBI if he had remained in the
     employ of CBI through the Employment Period at the salary determined under
     subsection (a) above.

          (y)  Continuation of disability income benefits pursuant to Section
     4(d) for so long as any disability may continue and continuation of
     directors and officers liability and indemnity insurance and corporate
     indemnity protection pursuant to Section 4(f) for so long as any liability
     may arise; in either case without regard to the Termination of the
     Employment Period.


          (z)  Within 30 days after each written request therefor by the
     Executive, cash advances or reimbursement for any fees or expenses actually
     incurred or reasonably expected to be incurred by the Executive in seeking
     other


                                      -12-


   13


     employment, including without limitation all travel and relocation expenses
     and all fees charged by any executive recruitment firm or firms or
     employment consulting or counseling firm or firms selected by the Executive
     in his sole discretion.

The amount of Termination payments described in subsections (a), (b), (c) and
(d) of this Section 6 shall be determined and paid in a lump sum within 30 days
of the Termination date by cashier's check or certified check of CBI or any of
its affiliated corporations delivered to Executive together with such
calculations, worksheets, or other information as may be necessary or
appropriate to ascertain the correctness of the computation of such amount and,
if applicable, of any reduction pursuant to Section 7. Any Termination payment
(or the value thereof) not paid on or before the date provided therefor by this
Section 6 shall bear interest after such date until paid at a rate per annum
during each month such amount remains unpaid of five percentage points in excess
of the prime rate as publicly announced by the First National Bank of Chicago or
its successor from time to time as in effect on the first day of each such
month.


     7.   Overall Limitations. Solely for the purposes of the computation of
benefits under this Agreement and notwithstanding any other provisions hereof,
payments to any Executive under this Agreement shall be reduced (but not below


                                      -13-


   14


zero) so that the present value, as determined in accordance with Section
280G(d)(4) of the Code, of such payments plus any other payments that must be
taken into account for purposes of any computation relating to Executive under
Section 280G(b)(2)(A)(ii) of the Code, shall not, in the aggregate, exceed 2.99
times Executive's "base amount," as that term is defined in Section 280G(b)(3)
of the Code. Notwithstanding any other provision hereof, no reduction in
payments under the limitation contained in the immediately preceding sentence
shall be applied to payments hereunder which do not constitute "excess parachute
payments" within the meaning the Code. Any payments in excess of the limitation
of this Section 7 or otherwise determined to be "excess parachute payments" made
to Executive hereunder are deemed to be overpayments which shall constitute an
amount owing from the Executive receiving them to CBI with interest from the
date of receipt by the Executive to the date of repayment (or offset) at the
applicable federal rate under Section 1274(d) of the Code, compounded
semi-annually, which shall be payable to CBI upon demand; provided, however,
that no repayment shall be required under this sentence if in the written
opinion of tax counsel satisfactory to the Executive and delivered to the
Executive and CBI such repayment does not allow such overpayment to be excluded
for federal income and excise tax purposes from the Executive's income for the
year of receipt or afford the


                                      -14-


   15


Executive a compensating federal income tax deduction for the year of repayment.

     8.   Non-Competition. Whether or not a Termination occurs, the Executive
agrees to continue all non-competition and confidentiality provisions, as
specified in any other agreement in effect on the Effective Date between the
Executive and CBI relating to confidential information, during (and to the
extent specified in such agreement, after) the Employment Period.

     9.   Mitigation. The Executive shall not be required to mitigate the amount
of any payment provided for under this Agreement by seeking other employment or
otherwise; provided, however, that if during the Employment Period Executive
accepts other employment in a position substantially equivalent to or better
than the position held by him with CBI, current cash compensation actually
received by the Executive during the Employment Period from such other
employment shall be applied to reduce Termination payments otherwise due under
subsections (a) and (c) of Section 6 of this Agreement.

     10.  Legal Fees and Expenses:

          (a) It is the intent of CBI that no Executive be required to incur the
     expenses associated with the enforcement of his rights under this Agreement
     by



                                      -15-


   16


     litigation or other legal action because the cost and expense thereof would
     substantially detract from the benefits intended to be extended to the
     Executive hereunder. Accordingly, if it should appear to the Executive that
     CBI has failed to comply with any of its obligations under this Agreement,
     or in the event that CBI or any other person takes any action to declare
     this Agreement void or unenforceable, or institutes any litigation designed
     to deny, or to recover from, the Executive the benefits intended to be
     provided to Executive hereunder, CBI irrevocably authorizes Executive from
     time to time to retain counsel of his choice, at the expense of CBI as
     hereafter provided, to represent Executive in connection with the
     initiation or defense of any litigation, arbitration or other legal action,
     whether by or against CBI or any director, officer, stockholder or other
     person affiliated with CBI, in any jurisdiction. CBI shall advance to the
     Executive within 30 days after each written request therefor any and all
     attorneys' and related fees and expenses actually incurred or reasonably
     expected to be incurred by the Executive in any such proceeding or
     otherwise as a result of CBI's failure to perform this Agreement or any
     provision hereof or as a result of CBI or any person contesting the
     validity or


                                      -16-


   17


     enforceability of this Agreement or any provision hereof; provided,
     however, that to the extent the Executive does not prevail in any such
     litigation, arbitration, or other legal action, the Executive shall repay
     to CBI the amount (without interest) of such attorney's fees and related
     fees and expenses previously advanced.

          (b)  CBI shall at its sole cost and expense obtain a commitment for an
     irrevocable clean letter of credit, substantially in the form of that
     attached hereto as Exhibit II and incorporated herein by reference (the
     "Letter of Credit"), to be issued by a commercial bank selected by CBI
     having total assets equivalent to at least $6 billion and either
     incorporated under the laws of, or having an office in, the United States
     or any State (the "Bank"), to secure for the benefit of Executive the total
     value of performance of CBI's obligations under this Agreement by providing
     that the total amount of all payments due to be paid by CBI to Executive
     under this Agreement shall be paid on a regular, periodic basis upon
     presentation by Executive to the Bank of a statement or statements prepared
     by Executive's counsel that such payments are due and owing, and that CBI
     has not performed its obligation to make such payments. CBI


                                      -17-


   18


     shall at its sole cost and expense obtain the issuance of the Letter of
     Credit pursuant to such committment not later than the Effective Date and
     shall pay all amounts and take all action necessary to maintain such Letter
     of Credit during the Employment Period and for two years thereafter and if,
     notwithstanding CBI's complete discharge of such obligations, such Letter
     of Credit shall be terminated or not renewed, CBI shall obtain a
     replacement irrevocable clean letter of credit on substantially the same
     terms and conditions as contained in the Letter of Credit drawn upon a
     commercial bank having total assets equivalent to at least $6 billion and
     either incorporated under the laws of, or having an office in, the United
     States or any State, which assures the Executive the benefits of this
     Agreement.

          11.  Notices. Any notices, requests, demands and other communications
provided for by this Agreement shall be sufficient if in writing and if sent by
registered or certified mail to the Executive at the last address he has filed
in writing with CBI or, in the case of CBI, at its principal executive offices.

          12.  Non-Alienation. The Executive shall not have any right to pledge,
hypothecate, anticipate or in any way create a


                                      -18-


   19


lien upon any amounts provided under this Agreement; and no benefits payable
hereunder shall be assignable in anticipation of payment either by voluntary or
involuntary acts, or by operation of law.

          13.  Governing Law. The provisions of this Agreement shall be 
construed in accordance with the laws of the State of Illinois.

          14.  Amendment. This Agreement may be amended or cancelled by mutual
agreement of the parties in writing without the consent of any other person and,
so long as the Executive lives, no person, other than the parties hereto, shall
have any rights under or interest in this Agreement or the subject matter
hereof.

          15.  Successors to the Company. Except as otherwise provided herein,
this Agreement shall be binding upon and inure to the benefit of CBI and any
successor of CBI.

          16.  Severability. In the event that any provision or portion of this
Agreement shall be determined to be invalid or unenforceable for any reason, the
remaining provisions of this



                                      -19-


   20


Agreement shall be unaffected thereby and shall remain in full force and effect.

such Person, shall be the Beneficial Owner (as such term is hereinafter defined)
of 20% or more of the shares of Common Stock then outstanding, but shall not
include the Company, any Subsidiary of the Company, any employee benefit plan of

ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under
the Securities Exchange Act


   22


of 1934, as amended (the "Exchange Act"), as in effect on the date of this
Agreement.

          1.4  A Person shall be deemed the "Beneficial Owner" of, and shall be
deemed to "beneficially own," any securities:


               (a) which such Person or any of such Person's Affiliates or

                              ADDENDUM TO AGREEMENT


     THIS ADDENDUM dated this 3rd day of October, 1989, to the AGREEMENT between
CBI Industries, Inc., a Delaware Corporation ("CBI") and Calvin E. Willoughby,
Jr. ("Executive") dated the 3rd day of October, 1989 (the "Agreement"):


                                WITNESSETH THAT:

     WHEREAS, CBI and the Executive mutually desire to modify the Agreement in
light of the enactment of the Tax Reform Act of 1986;

     NOW, THEREFORE, in consideration of the premises, it is hereby AGREED by
and between CBI and the Executive that the Agreement shall be modified as
follows:

     1.   Section 3 of the Agreement is amended by adding the following new
sentence immediately after the first sentence thereof:

     CBI shall maintain the position of Executive such that Executive is able to
     exercise the authorities, powers, functions and duties attached thereto as
     contemplated by this Section 3.


     2.   Subsection (b) of Section 5 of the Agreement is amended to read as
follows:


          (b) the resignation of the Executive from his employment upon 30 days
     written notice to CBI at any time following a significant change in the
     nature or scope of the Executive's authorities or duties from those
     described in Section 3, a reduction in total compensation


                                     Page 1

   28


     from that provided in Section 4, or the breach by CBI of any other
     provision of this Agreement, which change, reduction or breach is not
     restored or cured by CBI within 30 days after receiving written notice of
     such change, reduction or breach, reasonable directions for restoration or
     cure, and an offer to work from the Executive.


     3.   Section 5 of the Agreement is amended by deleting the words ", whether
or not a breach of this Agreement by CBI," from the sentence following
subsection (b).


     4.   Section 6 of the Agreement is amended (i) by deleting from the
introductory material preceding subsection (a) the words "equal (without
discount to present value) to the sum of" and substituting in lieu thereof the
words "equal to the present value (discounted at the greatest rate of interest
then payable by the First National Bank of Chicago on any federally insured
account into which Executive could deposit such lump sum amount and made
withdrawals therefrom without penalty at least as rapidly as compensation under
Section 4 would have been payable) of"; (ii) deleting from subsections (a) and
(c) the words "An amount equal to the aggregate" and substituting in lieu
thereof the word "The"; and (iii) deleting from the sentence following
subsection (z) the word "reduction" and substituting in lieu thereof the word
"enhancement".


     5.   The first sentence of subsection (d) of Section 6 is amended to read 
as follows:


     In the event any shares of CBI common stock (or other securities into which
     such shares may have been converted) previously awarded to Executive under
     any restricted stock award plans of CBI or separate agreements between
     Executive and CBI are forfeited by reason of such Termination, or in the
     event any stock option previously granted to Executive under any stock
     option plan of CBI terminates or ceases to be exercisable by


                                     Page 2
   29


     reason of such Termination, an amount in cash equal to the fair market
     value of such forfeited common stock (or other securities) as of the date
     of Termination plus the excess of the fair market value as of the date of
     Termination of stock subject to any such terminated option over the
     exercise price of such terminated option.


     6.   Section 7 of the Agreement is amended to read as follows:

     7.   Overall Indemnity. The parties intend that the payments in the nature 
     of compensation to be made by CBI to Executive under this Agreement shall
     be reasonable compensation for personal services to be rendered on or after
     the date of the Change in Control, including payments to an individual as
     damages for breach of contract, within the meaning of Section 280G(b)(4)(A)
     of the Internal Revenue Code of 1986, as amended (the "Code"). In the event
     that notwithstanding the previous sentence any excise tax under Section
     4999 of the Code is imposed on Executive as a direct or indirect result of
     payments made by CBI or its affiliates, whether or not such payments are
     made pursuant to this Agreement, CBI shall pay Executive an amount or, from
     time to time, amounts, equal to (i) the sum of all excise taxes imposed on
     Executive in respect of such payments, plus (ii) the aggregate amount of
     any interest, penalties, fines or additions to any tax which are imposed in
     connection with the imposition of such excise tax, plus (iii) all income
     and excise taxes imposed on Executive under the laws of any United States
     Federal, state or local government or taxing authority by reason of the
     payments required under clause (i) and clause (ii) and this clause (iii).
     CBI's obligation to pay such amounts to Executive pursuant to this Section
     7 shall continue for the period specified in Section 6501 of the Code
     during

                                     Page 3
   30

     which a tax may be assessed under Section 4999 of the Code (including any
     extensions of such period provided under Section 6503(a)(1) of the Code or
     requested by the Internal Revenue Service in connection with an audit of
     one or more of Executive's tax returns).


          If the Internal Revenue Service makes a claim against Executive which,
     if successful, would require CBI to make a payment under this Section 7,
     Executive agrees to contest the claim on request of CBI subject to the
     following conditions:


          (a)  Executive shall notify CBI of any such claim within 10 days of
     becoming aware thereof. In the event CBI desires the claim to be contested,
     it shall promptly (but in no event more than 30 days after the notice from
     Executive or such shorter time as the Internal Revenue Service may specify
     for responding to such claim) request Executive to contest the claim.
     Executive shall not make any payment of any tax which is the subject of the
     claim before Executive has given the notice or during the 30-day period
     thereafter unless Executive receives written instructions from CBI to make
     such payment together with an advance of funds sufficient to make the
     requested payment plus any amounts determined pursuant to clause (ii) and
     clause (iii) above as if such advance were an amount described in clause
     (i) above, in which case Executive will act promptly in accordance with
     such instructions.


          (b)  If CBI so requests, Executive will contest the claim by, at the
     direction of CBI, either paying the tax claimed and suing for a refund in
     the appropriate court or contesting the claim in the United States Tax
     Court; provided, however, that any request by CBI for


                                     Page 4
   31


     Executive to pay the tax shall be accompanied by an advance from CBI to
     Executive of funds sufficient to make the requested payment plus any
     amounts determined pursuant to clause (ii) and clause (iii) above as if
     such advance were an amount described in clause (i) above. If directed by
     CBI in writing Executive will take all action necessary to compromise or
     settle the claim, but in no event will Executive compromise or settle the
     claim or cease to contest the claim without the written consent of CBI;
     provided, however, that Executive may take any such action if Executive
     waives in writing his right to a payment under this Section 7 for any
     amounts payable in connection with such claim. Executive agrees to
     cooperate in good faith with CBI in contesting the claim and to comply with
     any reasonable request from CBI concerning the contest of the claim,
     including the pursuit of administrative remedies, the appropriate forum for
     any judicial proceeding, and the legal basis for contesting the claim. Upon
     request of CBI, Executive shall take appropriate appeals of any judgment or
     decision that would require CBI to make a payment under this Section 7.
     Provided that Executive is in compliance with the provisions of this
     section, CBI shall be liable for and indemnify Executive against any loss
     in connection with all costs and expenses, including attorneys' fees, which
     may be incurred as a result of contesting the claim, and shall provide to
     Executive within 30 days after each written request therefor by the
     Executive cash advances or reimbursement for all such costs and expenses
     actually incurred or reasonably expected to be incurred by the Executive as
     a result of contesting the claim.


          (c)  If CBI requests that Executive contest a claim and otherwise
     complies with its obligations under

                                     Page 5
   32


     this Section 7, it shall, except as otherwise stipulated in this Section 7,
     have no obligation to pay any amounts under Section 7 in respect of the
     claim until final determination occurs regarding Executive's liability
     under the claim. CBI's obligation to pay amounts under this Section 7 will
     be reduced by any refund obtained by Executive and interest paid thereon.


     7.   Section 9 of the Agreement is amended to read as follows:

          If during the Employment Period Executive accepts other employment in
     a position substantially equivalent to or better than the position held by
     him with CBI, compensation actually received by the Executive during the
     Employment Period from such other employment shall be applied to reduce
     Termination payments otherwise due under subsections (a) and (c) of Section
     6 of this Agreement; and coverage of the Executive under employee benefit
     plans described in subsection (x) of Section 6 of this Agreement shall be
     reduced or eliminated to the extent Executive is covered under similar
     plans incident to such other employment. In the event of any reduction
     under this Section 9 of Termination payments already paid by CBI to
     Executive, Executive shall upon 30 days written request from CBI repay to
     CBI the amount by which such Termination payment is reduced, without
     interest, and further reduced by any taxes attributable to such Termination
     payments to the extent Executive cannot recover such taxes through
     deductions of equivalent or greater value. Nothing in this Section 9 shall
     be construed to require Executive in mitigation of damages to accept
     employment in a position not substantially equivalent to or better than
     position held by him with CBI or to accept employment more than reasonable
     daily commuting

     Termination.

                             ADDENDUM TO AGREEMENT

     THIS ADDENDUM dated as of and made effective the 1st day of June, 1995 to 
the Agreement between CBI Industries, Inc., a Delaware corporation ("CBI") and
Calvin E. Willoughby ("Executive") of October 3, 1989 (the "Agreement").

                                WITNESSETH THAT

     WHEREAS, Executive has been offered an executive position in the employment
of Liquid Carbonic Industries Corporation ("LCC"), a wholly owned subsidiary of
CBI, subject to his resignation as an executive of Liquid Carbonic, Inc. 
("LCI"), a wholly owned subsidiary of CBI, and in order to induce Executive to
accept such position, CBI has assured Executive that he may at his election
retain the benefits of the Agreement in the event of a change of control of CBI
notwithstanding that Executive may at such time be an employee of LCC;

     WHEREAS, because of the similarity of the obligations undertaken by CBI
under the Agreement and the obligations of LCI under an Addendum to the 
Agreement dated as of August 18, 1993, and the obligations to be undertaken by
LCC under this Addendum, and for the general convenience of the parties, CBI and
the Executive mutually agree to permit LCC, a Delaware corporation, to become a
party to this Addendum, to relieve LCI of its obligations under the Addendum
dated as of August 18, 1993, and for LCC to assume the obligations hereinafter
undertaken; and

     WHEREAS, LCC also wishes to attract and retain well qualified executives
and both LCC and the Executive desire continuity of management in the event of
any Change of Ownership of LCC, and, accordingly LCC is willing to undertake
the obligations hereinafter stated.

     NOW, THEREFORE, it is hereby agreed by and between the parties to this
Addendum as follows:

          1.   LCI is relieved of all its obligations under the Addendum dated
     as of August 18, 1993.

          2.   For the purposes of this Addendum the term "Change in Ownership"

     to elect directors of LCC is not exercisable by CBI or another entity
     which directly or indirectly acquires stock of LCC in a leveraged buy-out
     in which the senior management of CBI participates.

          3.   In the event of a Change in Ownership of LCC, LCC and Executive
     agree to be bound by the terms of the Agreement as if the Agreement were
     an agreement between LCC and Executive, subject to the following changes:

               A.   "CBI Industries, Inc." and "CBI" shall be replaced by
          Liquid Carbonic Industries Corporation" and "LCC," respectively,
          wherever those terms appear in the Agreement, except in subsection
          6(d).

               B.   "Change in Control of CBI" and "Change in Control" shall be
          replaced by "Change in Ownership of LCC" and "Change in Ownership,"
          respectively, wherever those terms appear in the Agreement.

               C.   Section 2 of the Agreement is deleted and replaced by a new
          Section 2 for purposes of the obligations undertaken hereunder, which
          contains the definition of "Change in Ownership" as set forth in
          Section 2 of this Addendum.

   36

               D.   In Section 3 "date of execution hereof" shall mean date of

          option" are deleted from the second and ninth and tenth lines,
          respectively.

               F.   CBI's obligation under this Section 3 of this Addendum shall
          be to provide continuing directors and officers liability and
          indemnity insurance and corporate indemnity protection under 
          subsection 4(f) and 6(y) covering the time Executive was an officer
          or director of CBI.

               G.   In subsection 6(w):

                    (i)  the second and third lines are deleted and replaced
                         with the following words: "any pension benefit plan or
                         benefit restoration plan."

                    (ii) the words ";except that if ... determinable" are
                         deleted from the 14th through 21st lines on page 11
                         of the Agreement.

               H.   Subsection 10(b) is deleted.

               I.   Exhibits I and II are deleted.

          4.   It is understood and agreed by all parties to this Addendum that
     Executive shall only be entitled to receive the benefits from either the
     Agreement (between CBI and Executive only) or the Agreement as modified by
     this Addendum (among and between LCC, CBI and the Executive) and not from
     both. Upon the first to occur of either a Change in Control of CBI or a
     Change in Ownership of LCC, Executive shall be required within thirty (30)
     days to give to both CBI and LCC notice in writing as to which contractual
     arrangement provided for herein Executive desires to apply to his
     employment with LCC, after which notice the other contractual arrangement
     shall be null and void. In the event Executive elects to receive the
     benefits of the Agreement between CBI and Executive only without
     application of Section 3 of this Addendum, LCC shall be responsible for
     continuing Executive's employment and compensation within the meaning of
     Sections 3 and 4 of the Agreement commencing on the date of the event
     giving rise to Executive's notice hereunder, and CBI shall be responsible
     for termination payments under Section 6 of the Agreement in the event the
     employment of Executive with LCC is terminated within the meaning of
     Section 5 of the Agreement.

TO:  C.E. WILLOUGHBY

an Addendum to Agreement effective June 1, 1993 deleting Subsection 10(b) and
Exhibit II along with a $10 check in consideration of this modification. (For
your easy reference we have also enclosed copies of your original Agreement with
subsequent addendum.)

include a requirement that CBI provide an irrevocable clean letter of credit to
secure for the benefit of the Executive the payment of up to $100,000 for
attorneys fees incurred in enforcing the Agreement following a Change of
Control;

     NOW, THEREFORE, it is hereby agreed by and between the parties to this
Addendum that the Agreement shall be modified as follows:

          1.   Section 10 of the Agreement is amended by adding a new subsection
     (b) to read as follows:

               (b)  CBI shall at its sole cost and expense obtain a commitment
          for an irrevocable clean letter of credit, substantially in the form
          of that attached hereto as Exhibit II and incorporated herein by
          reference (the "Letter of Credit"), to be issued by a commercial bank
          selected by CBI having total assets equivalent to at least $6 billion
          and either incorporated under the laws of, or having an office in, the
          United States or any State (the "Bank"), to secure for the benefit of
          Executive the payment of up to $100,000 for attorneys fees incurred in
          enforcing the Agreement pursuant to Section 10(a) upon presentation by
          Executive to the Bank of a statement or statements prepared by
          Executive's counsel that such payments are due and owing and that CBI
          has not performed its obligations to make such payments. CBI shall at
          its sole cost and expense obtain the issuance of the Letter of Credit
          pursuant to such commitment not later than the Effective Date and
          shall pay all amounts and take all action necessary to maintain such
          Letter of Credit during the Employment Period and for two years
          thereafter and if, notwithstanding CBI's complete discharge of such
          obligations, such Letter of Credit shall be terminated or not renewed,
          CBI shall obtain a replacement irrevocable clean letter of credit on
          substantially the same terms and conditions as contained in the Letter
          of Credit drawn upon a commercial bank having total assets equivalent
          to at least $6 billion and either incorporated under the laws o, or
          having an office in, the United States of any State, which

   41

          assures the Executive the benefits of this Agreement. Nothing in this
          subsection(b) shall limit in any way CBI's obligations under
          subsection 10(a).

     THIS ADDENDUM dated as of and made effective the 18th day of August, 1993
to the Agreement between CBI Industries, Inc., a Delaware corporation ("CBI")
and Calvin E. Willoughby ("Executive") of October 3, 1989 (the "Agreement").


                                 WITNESSETH THAT

     WHEREAS, Executive has been offered an executive position in the employment
of Liquid Carbonic, Inc. ("LCI"), a wholly owned subsidiary of CBI, and in order
to induce Executive to accept such position, CBI has assured Executive that he
may at his election retain the benefits of the Agreement in the event of a
change of control of CBI notwithstanding that Executive may at such time be an
employee of LCI;

     WHEREAS, because of the similarity of the obligations undertaken by CBI
under the Agreement and the obligations to be undertaken by LCI under this
Addendum, and for the general convenience of the parties, CBI and the Executive
mutually agree to permit LCI, a Canadian corporation, to become a party to this
Addendum and for LCI to assume the obligations hereinafter undertaken; and

     WHEREAS, LCI also wishes to attract and retain well qualified executives
and both LCI and the Executive desire continuity of management in the event of
any Change in Ownership of LCI, and, accordingly LCI is willing to undertake the
obligations hereinafter stated.

     NOW, THEREFORE, it is hereby agreed by and between the parties to this
Addendum as follows:

          1.   For the purposes of this Addendum the term "Change in Ownership"
     shall mean the occurrence of an event pursuant to which the ultimate right
     to elect directors of LCI is not exercisable by CBI or another entity which
     directly or indirectly acquires stock of LCI in a leveraged buy-out in
     which the senior management of CBI participates.

          2.   In the event of a Change in Ownership of LCI, LCI and Executive
     agree to be bound by the terms of the Agreement as if the Agreement were an
     agreement between LCI and Executive, subject to the following changes:

               A.   "CBI Industries, Inc." and "CBI" shall be replaced by
          "Liquid Carbonic, Inc." and "LCI," respectively, wherever those terms
          appear in the Agreement, except in subsection 6(d).

               B.   "Change in Control of CBI" and "Change in Control" shall be
          replaced by "Change in Ownership of LCI" and "Change in Ownership,"
          respectively, wherever those terms appear in the Agreement.


                                      -1-

   50

               C.   Section 2 of the Agreement is deleted and replaced by a new
          Section 2 for purposes of the obligations undertaken hereunder, which
          contains the definition of "Change in Ownership" as set forth in
          Section 1 of this Addendum.

               D.   In Section 3 "date of execution hereof" shall mean date of
          execution of this Addendum.

          option" are deleted from the second and ninth and tenth lines,
          respectively.

               F.   CBI's obligation under Section 2 of this Addendum shall be
          to (i) provide continuing directors and officers liability and
          indemnity insurance and corporate indemnity protection under
          subsections 4(f) and 6(y) covering the time Executive was an officer
          or director of CBI, and (ii) provide post-retirement benefits under
          the Survivor's Agreement as provided in the Addendum to the Agreement
          dated September 12, 1986, between CBI and Executive.

               G.   In subsection 6(w):

                    (i)  the second and third lines are deleted and replaced
                         with the following words: "any pension benefit plan or
                         benefit restoration plan."

                    (ii) the words "; except that if ... determinable" are
                         deleted from the 14th through 21st lines on page 11
                         of the Agreement.

               H.   Subsection 10(b) is deleted.

               I.   Exhibits I and II are deleted.

          3.   It is understood and agreed by all parties to this Addendum that
     Executive shall only be entitled to receive the benefits from either the
     Agreement (between CBI and Executive only) or the Agreement as modified by
     this Addendum (among and between LCI, CBI and the Executive) and not from
     both. Upon the first to occur of either a Change in Control of CBI or a
     Change in Ownership of LCI, Executive shall be required within thirty (30)
     days to give to both CBI and LCI notice in writing as to which contractual
     arrangement provided for herein Executive desires to apply to his
     employment with LCI, after which notice the other contractual arrangement
     shall be null and void. In the event Executive elects to receive the
     benefits of the Agreement between CBI and Executive only without
     application of Section 2 of this Addendum, LCI shall be responsible for
     continuing Executive's employment and compensation within the meaning of
     Sections 3 and 4 of the Agreement commencing on the date of the event
     giving rise to Executive's notice hereunder, and CBI shall be responsible
     for termination payments under Section 6 of the Agreement


                                      -2-

   51

     in the event the employment of Executive with LCI is terminated within the
     meaning of Section 5 of the Agreement.
