                                CLIMACHEM, INC.

        OFFER TO EXCHANGE ITS 10 3/4% SERIES B SENIOR NOTES DUE 2007 FOR
                               ANY AND ALL OF ITS
                   OUTSTANDING 10 3/4% SENIOR NOTES DUE 2007

      THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON
                       __________, 1998, UNLESS EXTENDED

          ClimaChem, Inc., an Oklahoma corporation (the "Company"), a wholly
owned subsidiary of LSB Industries, Inc., a Delaware corporation ("LSB"), is
engaged, through its subsidiaries, in the manufacture and sale of (i) chemical
products for the explosives, agricultural and industrial acids markets and (ii)
a broad range of hydronic fan coils and water source heat pumps as well as other
products in commercial and residential heating, ventilation and air conditioning
("HVAC Systems").  See "The Company."  The Company hereby offers (the "Exchange
Offer"), upon the terms and conditions set forth in this Prospectus (the
"Prospectus") and the accompanying Letter of Transmittal (the "Letter of
Transmittal"), to exchange $1,000 principal amount of its 10 3/4% Series B
Senior Notes due 2007 (the "New Notes") registered under the Securities Act of
1933, as amended (the "Securities Act"), pursuant to a Registration Statement of
which this Prospectus is a part, for each $1,000 principal amount of its
outstanding 10 3/4% Senior Notes due 2007 (the "Old Notes"), of which $105
million principal amount is outstanding.  The Old Notes were sold by the Company
on November 26, 1997, to Wasserstein Perella Securities, Inc., who subsequently
resold the Old Notes to qualified institutional buyers pursuant to Rule 144A
under the Securities Act ("Initial Offering").  See "Initial Offering."  The
form and terms of the New Notes are the same as the form and terms of the Old
Notes (which they replace), except the New Notes will bear a Series B
designation and will have been registered under the Securities Act and,
therefore, will not bear legends restricting their transfer and will not contain
certain provisions relating to liquidated damages which were included in the
terms of the Old Notes in certain circumstances relating to the timing of the
Exchange Offer.  The New Notes will evidence the same debt as the Old Notes
(which they replace) and will be issued under and be entitled to the benefits of
an Indenture, dated November 26, 1997 (the "Indenture"), between the Company ,
the Guarantors (as defined) and Bank One, NA, as trustee (the "Trustee")
governing the Old Notes and the New Notes.  The Old Notes and the New Notes are
sometimes referred to herein collectively as the "Notes." See "The Exchange
Offer" and "Description of Securities-Notes."

                   (COVER PAGE CONTINUED ON FOLLOWING PAGES)

SEE "RISK FACTORS," BEGINNING ON PAGE 17, FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY HOLDERS WHO TENDER THEIR OLD NOTES IN THE EXCHANGE
OFFER.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION OR
ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
PROSPECTUS, ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

INFORMATION CONTAINED HEREIN IS SUBJECT TO COMPLETION OR AMENDMENT.  A
REGISTRATION STATEMENT RELATING TO THESE SECURITIES HAS BEEN FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION.  THESE SECURITIES MAY NOT BE SOLD NOR MAY
OFFERS TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT BECOME
EFFECTIVE.  THIS PROSPECTUS SHALL NOT CONSTITUTE AN OFFER TO SELL OR THE
SOLICITATION OF AN OFFER TO BUY NOR SHALL THERE BE ANY SALE OF THESE SECURITIES
IN ANY STATE IN WHICH SUCH OFFER, SOLICITATION OR SALE WOULD BE UNLAWFUL PRIOR
TO THE REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF ANY SUCH
STATE.

(COVER PAGE CONTINUED)

          The Notes bear interest at a rate of 10 3/4% per annum, payable
semiannually on June 1 and December 1 of each year, commencing June 1, 1998.
The Notes will mature on December 1, 2007, and will not be subject to a sinking
fund requirement.  The Notes will be redeemable by the Company, in whole or in
part, at any time on and after December 1, 2002, at the redemption prices set
forth herein, plus accrued and unpaid interest and Liquidated Damages (as
defined herein), if any, to the redemption date.  Notwithstanding the foregoing,
at any time on or before December 1, 2000, the Company, at its option, may
redeem in the aggregate up to $35 million aggregate principal amount of the
Notes at 110.750% of the aggregate principal amount so redeemed plus accrued and
unpaid interest and Liquidated Damages (as defined), if any, to the redemption
date with the net proceeds of one or more Public Equity Offerings (as defined),
provided not less than $65 million aggregate original principal amount of the
Notes are outstanding immediately after the occurrence of any such redemption.
See "Description of Notes-Optional Redemption."

          The New Notes will be, as the Old Notes (which they replace) are,
senior unsecured obligations of Company, and will, as the Old Notes (which they
replace), rank pari passu in right of payment to all existing and future senior
unsecured indebtedness of Company.  The New Notes will be, as the Old Notes
(which they replace) are, fully and unconditionally guaranteed (the
"Guarantees"), on an unsecured senior basis by substantially all of the existing
and future subsidiaries of the Company (the "Guarantors").  El Dorado Nitrogen
Company ("EDNC"), a current subsidiary of the Company, is not a Guarantor.  The
Notes and the Guarantees will be effectively subordinated to all existing and
future secured indebtedness of Company and its subsidiaries, and to all existing
and future secured and unsecured indebtedness of the subsidiaries of the Company
which are not Guarantors.  The lender under the Revolving Credit Facility (as
defined) has a security interest in the accounts receivable, inventory,
proprietary rights, books and records, and proceeds thereof, of certain
subsidiaries of the Company that are borrowers and guarantors under the
Revolving Credit Facility.  The Company has guaranteed the obligations of those
subsidiaries of the Company that are borrowers under the Revolving Credit
Facility.  In addition, certain other assets of certain subsidiaries of the
Company are subject to liens and security interests granted in connection with
certain other existing lending and leasing arrangements.  See "Description of
Other Indebtedness." After giving effect to the application of the net proceeds
received by the Company from the Initial Offering, as of November 30, 1997, the
aggregate principal amount of secured indebtedness of the Company was
approximately $23.3 million.  In addition, after giving effect to the
application of the net proceeds received by the Company from the Initial
Offering, the Company had $43.5 million of additional borrowing availability
under the Revolving Credit Facility as of November 30, 1997, and US$2.5 million
of additional borrowing availability under the TES Revolving Facility (as
defined) as of November 30, 1997. See "Description of Other Indebtedness." The
Indenture permits the Company and the Guarantors to incur additional
indebtedness, subject to certain limitations, and contains no limitation on the
ability of the Company's parent, LSB, to incur additional indebtedness.  See
"Capitalization" and "Description of Notes."

          In the event of a Change of Control (as defined), holders of the Notes
will have the right to require the Company to purchase its Notes at 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, to the repurchase date.  See "Risk Factors-
Repurchase of Notes Upon Change of Control" and "Description of Notes."  In
addition, the Company is obligated in certain instances to make offers to
repurchase the Notes at a purchase price in cash equal to 100% of the principal
amount thereof plus accrued and unpaid proceeds of certain asset sales.  See
"Description of Notes-Certain Covenants."

          The Company will accept for exchange any and all Old Notes validly
tendered and not withdrawn prior to 5:00 p.m., New York City time on
___________, 1998, unless extended by the Company in its sole discretion (the
"Expiration Date").  Tenders of Old Notes may be withdrawn at any time prior to
5:00 p.m. on the Expiration Date. The Exchange Offer is subject to certain
customary conditions.  The Old Notes were sold by Company on November 26, 1997,
to the Initial Purchaser (as defined) in a transaction (the "Initial Offering")
not registered under the Securities Act in reliance upon an exemption under the
Securities Act.  The Initial Purchaser subsequently placed

                                      -2-

(COVER PAGE CONTINUED)


the Old Notes with qualified institutional buyers in reliance upon Rule 144A
under the Securities Act. Accordingly, the Old Notes may not be reoffered,
resold, or otherwise transferred in the United States unless registered under
the Securities Act or unless an applicable exemption from the registration
requirements of the Securities Act is available. The New Notes are being offered
hereunder in order to satisfy the obligations of Company under the Registration
Rights Agreement (as defined) entered into between the Company, the Guarantors,
and the Initial Purchaser in connection with the Initial Offering.  See "The
Exchange Offer."

          Based on no-action letters issued by the staff of the Securities and
Exchange Commission (the "Commission") to third parties, the Company believes
the New Notes issued pursuant to the Exchange Offer may be offered for resale,
resold and otherwise transferred by any holder thereof (other than any such
holder that is an "affiliate" of Company within the meaning of Rule 405 under
the Securities Act) without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such New Notes are
acquired in the ordinary course of such holder's business and such holder has no
arrangement or understanding with any person to participate in the distribution
of such New Notes.  See "The Exchange Offer-Resale of the New Notes."  Each
broker-dealer (a "Participating Broker-Dealer") that receives New Notes for its
own account pursuant to the Exchange Offer must acknowledge that it will deliver
a prospectus in connection with any resale of such New Notes.  The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
Participating Broker-Dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.  This Prospectus, as it
may be amended or supplemented from time to time, may be used by a Participating
Broker-Dealer in connection with the resales of New Notes received in exchange
for Old Notes where such Old Notes were acquired by such Participating Broker-
Dealer as a result of market making activities or other trading activities. The
Company has agreed that, for a period of 180 days after the consummation of the
Exchange Offer, it will make this Prospectus available to any Participating
Broker-Dealer for use in connection with any such resale.  See "Plan of
Distribution."

          Holders of Old Notes not tendered and accepted in the Exchange Offer
will continue to hold such Old Notes and will be entitled to all the rights and
benefits and will be subject to the limitations applicable thereto under the
Indenture and with respect to transfer under the Securities Act.  The Company
will pay all the expenses incurred by it incident to the Exchange Offer.  See
"The Exchange Offer."

          There has not been previously any public market for the Old Notes or
the New Notes.  The Company does not intend to list the New Notes on any
securities exchange or to seek approval for quotation through any automated
quotation system.  The Old Notes are currently eligible for trading in the
Private Offerings, Resales and Trading through Automated Linkages ("PORTAL")
market.  However, there can be no assurance that an active market for the New
Notes will develop.  See "Risk Factors-Absence of a Public Market Could
Adversely Affect the Value of the Notes."  Moreover, to the extent that Old
Notes are tendered and accepted in the Exchange Offer, the trading market for
untendered and tendered but unaccepted Old Notes could be adversely affected.

          The New Notes will be available initially in book-entry from, and the
Company expects that the New Notes issued pursuant to this Exchange Offer will
be issued in the form of a Global Note, which will be deposited with, or on
behalf of, The Depository Trust Company (the "Depository") and registered in its
name or in the name of Cede & Co., its nominee. Beneficial interests in the
Global Note will be shown on, and transfer thereof will be effected through,
records maintained by the Depository and its participants.  After the initial
issuance of the Global Note, New Notes in certificated form will be issued in
exchange for the Global Note on the terms set forth in the Indenture.  See
"Description of Notes-Book-Entry, Delivery and Form."

                                    SUMMARY

THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY, AND SHOULD BE READ IN
CONJUNCTION WITH, THE MORE DETAILED INFORMATION AND FINANCIAL STATEMENTS,
INCLUDING THE NOTES THERETO, APPEARING ELSEWHERE IN THIS PROSPECTUS.  THE
COMPANY IS A WHOLLY OWNED SUBSIDIARY OF LSB.  THE COMPANY OWNS, THROUGH ITS
SUBSIDIARIES, SUBSTANTIALLY ALL OF THE OPERATIONS COMPRISING THE CHEMICAL
BUSINESS AND CLIMATE CONTROL BUSINESS OWNED BY LSB PRIOR TO THE INITIAL
OFFERING. UNLESS THE CONTEXT OTHERWISE REQUIRES, ALL REFERENCES TO THE "COMPANY"
IN THIS PROSPECTUS REFERS TO CLIMACHEM, INC. AND ITS SUBSIDIARIES AND DOES NOT
REFER TO LSB AND ITS OTHER SUBSIDIARIES.  THIS SUMMARY IS ALSO QUALIFIED BY THE
"SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS."

                                  THE COMPANY

          The Company, a wholly owned subsidiary of LSB, is engaged, through its
subsidiaries, in the manufacture and sale of (i) chemical products for the
explosives, agricultural and industrial acids markets (the "Chemical Business")
and (ii) a broad range of hydronic fan coils and water source heat pumps as well
as other products used in commercial and residential heating, ventilation and
air conditioning ("HVAC") systems (the "Climate Control Business"). For the
twelve months ended September 30, 1997, the Company had net sales of $260.2
million and EBITDA (as defined) of $21.4 million.

Chemical Business

          The Company's Chemical Business manufactures three principal product
lines that are derived from anhydrous ammonia: (1) fertilizer grade ammonium
nitrate for the agricultural industry, (2) explosive grade ammonium nitrate for
the mining industry and (3) concentrated, blended and mixed nitric acid for
industrial applications. In addition, the Company also produces sulfuric acid
for commercial applications primarily in the paper industry. The Chemical
Business' products are sold in niche markets where the Company believes it can
establish a position as a market leader.

          Agricultural Products.   The Chemical Business is a major manufacturer
of fertilizer grade ammonium nitrate, which it markets primarily in Texas,
Arkansas and the surrounding regions. This market, which is in close proximity
to its El Dorado, Arkansas facility (the "El Dorado Facility"), includes a high
concentration of pasture land and row crops which favor ammonium nitrate over
other nitrogen-based fertilizers. The Company has developed the leading market
position in Texas by emphasizing high quality products, customer service and
technical advice. Using a proprietary prilling process, the Company produces a
high performance ammonium nitrate fertilizer that, because of its uniform size,
is easier to apply than many competing nitrogen-based fertilizer products. The
Company believes that its "E-2" brand ammonium nitrate fertilizer is recognized
as a premium product within its primary market. In addition, the Company has
developed long term relationships with end users through its network of 21 owned
and operated wholesale and retail distribution centers.

          Explosives.   The Chemical Business manufactures low density ammonium
nitrate-based explosives including bulk explosives used in surface mining. In
addition, the Company manufactures and sells a branded line of packaged
explosives used in construction, quarrying and other applications, particularly
where controlled explosive charges are required. The Company's bulk explosives
are marketed primarily through six Company-owned distribution centers, four of
which are located in close proximity to the customers' surface mines in the coal
producing states of Kentucky, West Virginia, Illinois, and Indiana. The Company,
through its Australian subsidiary, also manufactures and distributes bulk and
packaged explosives in Australia and New Zealand. The Company emphasizes value-
added customer services and specialized product applications for its bulk
explosives. Most of the sales of bulk explosives are to customers who work
closely with the Company's technical representatives in meeting their specific
product needs. In addition, the Company sells bulk explosives to independent
wholesalers and to other explosives companies. Packaged explosives are used for

                                      -6-
<PAGE>
 
applications requiring controlled explosive charges and typically command a
premium price and produce higher margins. The Company believes its Slurry
packaged explosive products are among the most widely recognized in the
industry. Slurry packaged explosive products are sold nationally and
internationally to other explosive companies and end-users.

          Industrial Acids.   The Chemical Business manufactures and sells
industrial acids, primarily to the food, paper, chemical and electronics
industries. The Company is the leading supplier to third parties of concentrated
nitric acid which is a special grade of nitric acid used in the manufacture of
plastics, pharmaceuticals, herbicides, explosives and other chemical products.
In addition, the Company produces and sells regular, blended and mixed nitric
acid and a variety of grades of sulfuric acid. The Company competes on the basis
of price and service, including on-time reliability and distribution
capabilities. The Company operates the largest fleet of tankcars in the
concentrated nitric acid industry which provides it with a significant
competitive advantage in terms of distribution costs and capabilities. In
addition, the Company provides inventory management as part of the value-added
services it offers to its customers.

          The Company has identified concentrated nitric acid as a strategic
product line for its Chemical Business due to attractive levels of
profitability, increased diversity of end markets and the ability to compete on
a value added service basis. To support further growth in its nitric acid
business, the Company undertook the construction of a concentrated nitric acid
plant (the "DSN Plant") located at the El Dorado Facility. The DSN Plant uses a
newer and more efficient process to produce concentrated nitric acid directly
from anhydrous ammonia, in contrast to the conventional process which requires
the input of regular nitric acid, an intermediate step, to produce concentrated
nitric acid.

          The DSN Plant.   Since January 1, 1994, the Chemical Business has
spent approximately $32.0 million to install the DSN Plant. The DSN Plant began
limited operations in 1995, and such limited operations continued due to certain
mechanical and design problems associated with the plant's construction and
installation. As a result of such problems, production at the DSN Plant was
limited to approximately 170 tons per day (60% of its stated capacity of 285
tons per day assuming 338 days of annual production) during the twelve months
ended September 30, 1997. In October 1997, management completed certain
corrective actions at the DSN Plant. As a result of these corrective actions,
the DSN Plant has the capacity to operate at approximately 285 tons per day.
However, due to customer specifications and inventory constraints, among other
things, the DSN Plant has been operating at approximately 260 tons per day since
the corrective actions were completed. Based on normalized production (assuming
338 days of annual production) at 260 tons per day, the Company believes it will
be able to produce concentrated nitric acid at a cost per ton approximately $65
per ton lower than at the production levels of 170 tons per day in the prior
period. While the Company will seek to market the additional capacity of
concentrated nitric acid output to commercial markets, there can be no assurance
that the Company will be able to sell all of the additional capacity in this
market. However, to the extent that there is insufficient demand for the
concentrated nitric acid, the Company believes it can profitably use
concentrated nitric acid in the production of mixed and blended acids and
ammonium nitrate based fertilizer and explosives (although at lower margins than
if the production were sold as concentrated nitric acid). See "Risk Factors -
DSN Plant Design Issues," "The Company - Chemical Business - DSN Plant" and
"Special Note Regarding Forward-Looking Statements."

Climate Control Business

          The Company's Climate Control Business manufactures and sells a broad
range of standard and custom designed hydronic fan coils and water source heat
pumps as well as other products for use in commercial and residential HVAC
systems. Demand for the Climate Control Business products is driven by the
construction of commercial, institutional and residential buildings, the
renovation of existing buildings and the replacement of existing systems. The
Climate Control Business' commercial products are used in a wide variety of
buildings, such as hotels, motels, office buildings, schools, universities,
apartments, condominiums, hospitals, nursing homes, extended care facilities,
supermarkets and superstores. Many of the Company's products are targeted to
meet increasingly stringent indoor air quality and energy efficiency standards.

          Hydronic Fan Coils.   The Climate Control Business is the leading U.
S. provider of hydronic fan coils targeted

                                      -7-
<PAGE>
 
to the commercial and institutional markets in the United States. Hydronic fan
coils use heated or chilled water, provided by a centralized chiller and boiler,
through a water pipe system to condition the air and allow individual room
control. Hydronic fan coil systems are quieter and have longer lives and lower
maintenance costs than comparable systems for individual room control
applications. The Company believes that its product line of hydronic fan coils
is the most extensive offered by any domestic producer. The breadth of this
product line coupled with customization capability provided by a flexible
manufacturing process are important components of the Company's strategy for
competing in the commercial and institutional renovation and replacement
markets.

          Water Source Heat Pumps.   The Company is a leading U.S. provider of
water source heat pumps to the commercial construction and renovation markets.
These are highly efficient heating and cooling units which enable individual
room climate control through the transfer of heat through a water pipe system
which is connected to a centralized cooling tower or heat injector. Water source
heat pumps enjoy a broad range of commercial applications, particularly in
medium to large sized buildings with many small, individually controlled spaces.
The Company believes the market for commercial water source heat pumps will
continue to grow due to the higher efficiency, lower operating cost and long
life of such systems as compared to other air conditioning and heating systems,
as well as to the emergence of the replacement market for these systems.

          Geothermal Products.   The Climate Control Business is a pioneer in
the use of geothermal water source heat pumps in residential and commercial
applications. Geothermal systems, which circulate water through an underground
heat exchanger, are among the most energy efficient systems available. The
Company believes that an aging installed base of residential HVAC systems,
coupled with the longer life, lower cost to operate and relatively short payback
periods of geothermal systems, will continue to increase demand for its
geothermal products, particularly in the residential replacement market.

Old Notes...................    The Old Notes were sold by the Company on
                                November 26,1997 (the "Issue Date"), to
                                Wasserstein Perella Securities, Inc. (the
                                "Initial Purchaser") pursuant to a Purchase

                                the Initial Purchaser. The Initial Purchaser
                                subsequently resold the Old Notes to qualified
                                institutional buyers pursuant to Rule 144A under
                                the Securities Act.

Registration Rights Agreement.. Pursuant to the Purchase Agreement, the Company,
                                the Guarantors and the Initial Purchaser entered
                                into a Registration Rights Agreement, dated as
                                November 26, 1997 (the "Registration Rights
                                Agreement"), which grants the holders of the Old
                                Notes certain exchange and registration rights.
                                The Exchange Offer is intended to satisfy such
                                exchange rights which terminate upon the
                                consummation of the Exchange Offer.

Securities Offered............  $105 million aggregate principal amount of 10
                                3/4% Series B Notes due 2007 of the Company.

The Exchange Offer............  $1,000 principal amount of the New Notes in

                                aggregate principal amount of Old Notes are
                                outstanding. The Company will issue the New
                                Notes in exchange for the Old Notes to holders
                                of the Old Notes on or promptly after the
                                Expiration Date.

Transfer Restrictions........   Based on an interpretation by the staff of the
                                Commission set forth in no-action letters issued
                                to third parties, the Company believes that New
                                Notes issued pursuant to the Exchange Offer in
                                exchange for Old Notes may be offered for

                                and that such holder does not intend to
                                participate and has no arrangement or
                                understanding with any person to participate in
                                the distribution of such New Notes. Each holder
                                accepting the Exchange Offer is required to

                                or understanding with any person to participate
                                in the distribution of such New Notes.

                                Old Notes for its own account as a result of
                                market-making activities or other trading
                                activities may be a statutory underwriter. Each

                                any resale of such New Notes. The Letter of
                                Transmittal states that by so acknowledging and
                                by delivering a prospectus, a Participating
                                Broker-Dealer will not be deemed to admit that
                                it is an "underwriter" within the meaning of the
                                Securities Act. This Prospectus, as it may be
                                amended or supplemented from time to time, may
                                be used by a Participating Broker-Dealer will
                                not be deemed to admit that it is an
                                "underwriter" within the meaning of the
                                Securities Act. This Prospectus, as it may be
                                amended or supplemented from time to time, may
                                be used by a Participating Broker-Dealer in
                                connection with resale of New Notes received in
                                exchange for Old Notes where such Old Notes were
                                acquired by such Participating Broker-Dealer as
                                a result of market-making activities or other
                                trading activities. The Company has agreed that,
                                for a period of 180 days after the Expiration
                                Date, it will make this Prospectus available to
                                any Participating Broker-Dealer for use in
                                connection with any such resale. See "Plan of
                                Distribution."

                                Any holder who tenders in the Exchange Offer
                                with the intention to participate, or for the
                                purpose of participating, in a distribution of
                                the New Notes could not rely on the position of
                                the staff of the Commission enunciated in no-
                                action letters and, in the absence of an
                                exemption therefrom, must comply with the
                                registration and prospectus delivery
                                requirements of the Securities Act in connection
                                with any resale transaction. Failure to comply
                                with such requirements in such instance may
                                result in such holder incurring liability under
                                the Securities Act for which the holder is not
                                indemnified by the Company.

Expiration Date...............  5:00 p.m., New York City time, on             ,
                                1998, unless the Exchange Offer is extended in
                                which case the term "Expiration Date" means the
                                latest date and time to which the Exchange Offer
                                is extended.

Accrued Interest on the New
Notes and the Old
Notes.........................  Each New Note will bear interest from its
                                issuance date. Holders of Old Notes that are
                                accepted for exchange will receive, in cash,
                                accrued interest thereon to, but not including,
                                the issuance date of the New Notes. Such
                                interest will be paid with the first interest
                                payment on the New Notes. Interest on the Old
                                Notes accepted for exchange will cease to accrue
                                upon issuance of the New Notes.

Conditions to the Exchange
Offer.........................  The Exchange Offer is subject to certain
                                customary conditions, which may be waived by the
                                Company. See "The Exchange Offer-Conditions."

Procedures for Tendering
Old Notes.....................  Each holder of Old Notes wishing to accept the
                                Exchange Offer must complete, sign and date the
                                accompanying Letter of Transmittal, or a
                                facsimile thereof or transmit an Agent's Message
                                (as defined) in connection with a book-entry
                                transfer, in accordance with the instructions
                                contained herein and therein, and mail or
                                otherwise deliver such Letter of Transmittal,
                                such facsimile or such Agent's Message,

                                      -10-
<PAGE>
 
                                together with the Old Notes and any other
                                required documentation, to the Exchange Agent
                                (as defined) at the address set forth herein. By
                                executing the Letter of Transmittal or Agent's
                                Message, each holder will represent to the
                                Company that, among other things, the New Notes
                                acquired pursuant to the Exchange Offer are
                                being obtained in the ordinary course of
                                business of the person receiving such New Notes,
                                whether or not such person is the holder, that
                                neither the holder nor any such other person (i)
                                has any arrangement or understanding with any
                                person to participate in the distribution of
                                such New Notes, (ii) is engaging or intends to
                                engage in the distribution of such New Notes, or
                                (iii) is an "affiliate," as defined under Rule
                                405 of the Securities Act, of the Company. See
                                "The Exchange Offer-Purpose and Effect of the
                                Exchange Offer" and "-Procedures for Tendering."

Untendered Old Notes..........  Following the consummation of the Exchange
                                Offer, holders of Old Notes eligible to
                                participate but who do not tender their Old
                                Notes will not have any further exchange rights
                                and such Old Notes will continue to be subject
                                to certain restrictions on transfer.
                                Accordingly, the liquidity of the market for
                                such Old Notes could be affected adversely.

Consequences of Failure
Exchange......................  The Old Notes that are not exchanged pursuant to
                                the Exchange Offer will remain restricted
                                securities. Accordingly, such Old Notes may be
                                resold only (i) to the Company, (ii) pursuant to
                                Rule 144A or Rule 144 under the Securities Act
                                or pursuant to some other exemption under the
                                Securities Act, (iii) outside the United States
                                to a foreign person pursuant to the requirements
                                of Rule 904 under the Securities Act, or (iv)
                                pursuant to an effective registration statement
                                under the Securities Act. See "The Exchange
                                Offer-Consequences of Failure to Exchange."

Shelf Registration Statement..  If applicable interpretations of the staff of
                                the Commission do not permit the Company to
                                effect the Exchange Offer or permit a Holder to
                                participate in the Exchange Offer or, in the
                                case of any Holder of Notes that participates in
                                the Exchange Offer, such Holder does not receive
                                freely tradable New Notes on the date of the
                                exchange for tendered Notes, or if for any
                                reason the Exchange Offer is not consummated
                                within 180 days after the Issue Date, or,
                                subject to certain conditions, upon the request
                                of the Initial Purchaser or the Holders of a
                                majority in aggregate principal amount of the
                                Notes, the Company will, at its cost, file with
                                the Commission a shelf registration statement
                                (the "Shelf Registration Statement") to cover
                                resales of Notes by the Holders thereof. The
                                Company will use its best efforts to cause the
                                applicable registration statement to be declared
                                effective by the Commission as promptly as
                                practicable after the date of filing. The
                                Company has agreed to maintain the effectiveness
                                of the Shelf Registration Statement for, under
                                certain circumstances, a maximum of 24 months
                                from a date which is 150 days following the
                                Issue Date, or such shorter period ending when
                                (i) the securities covered by the Shelf
                                Registration Statement have been sold or (ii) a
                                subsequent shelf registration statement covering
                                such securities has been declared effective
                                under the Securities Act.

Special Procedures for
Beneficial Owners.............  Any beneficial owner whose Old Notes are
                                registered in the name of a broker, dealer,
                                commercial bank, trust company or other nominee
                                and who wishes to tender should contact promptly
                                such registered holder and instruct such
                                registered holder to tender on such beneficial
                                owner's behalf. If such beneficial owner wishes
                                to tender on such owner's own behalf, such owner
                                must, prior to completing and executing the
                                Letter of Transmittal and delivering its Old
                                Notes, either make appropriate arrangements to
                                register ownership of the Old Notes in such
                                owner's name or obtain a properly completed bond
                                power from the registered holder. The transfer
                                of registered ownership may take considerable
                                time. The Company will keep the Exchange Offer
                                open for not less than 30 business days in order
                                to provide for the transfer of registered
                                ownership.

Issuer........................  ClimaChem, Inc.

General.......................  The form and terms of the New Notes are the same
                                as the form and terms of the Old Notes (which
                                they replace) except that (i) the New Notes bear
                                a Series B designation, (ii) the New Notes have
                                been registered under the Securities Act and,
                                therefore, will not bear legends restricting the
                                transfer thereof, and (iii) the holders of New
                                Notes will not be entitled to certain rights
                                under the Registration Rights Agreement,
                                including the provisions providing for
                                liquidated damages in certain circumstances
                                relating to the timing of the Exchange Offer,
                                which rights will terminate when the Exchange
                                Offer is consummated. See "The Exchange Offer-

                                guaranteed by substantially all of the existing
                                and all of the future Subsidiaries of the

                                issued at a redemption price of 110.750% of the
                                principal amount thereof, plus accrued and
                                unpaid interest, if any, thereon, plus

                                Notes in whole or in part at a redemption price
                                of 101% of the principal amount thereof plus
                                accrued and unpaid interest, if any, thereon,

                                repurchase. See "Description of Notes--Certain

Ranking.......................  The New Notes will be, as Old Notes (which they
                                replace) are, senior unsecured obligations of
                                the Company and will rank pari passu in right of
                                payment to all future and existing senior
                                unsecured indebtedness of the Company. The New
                                Notes will be effectively subordinated to all
                                existing and future senior secured indebtedness
                                of the Company and its subsidiaries and to all
                                existing and future secured and unsecured
                                indebtedness of the subsidiaries of the Company
                                which are not Guarantors. As of November 30,
                                1997, after giving effect to the Initial
                                Offering and the application of the net proceeds
                                therefrom, the Company had a credit under the
                                Revolving Credit Facility (as defined) of $0.2
                                million, US$3.3 million of borrowings
                                outstanding under the TES Revolving Facility (as
                                defined), a maximum of $43.5 million of
                                availability for borrowings under the Revolving
                                Credit Facility, US$2.5 million of availability
                                for borrowings under the TES Revolving Facility,
                                and $20.2 million of other secured indebtedness,
                                all of which is effectively senior to the New
                                Notes. See "Description of Other Indebtedness."

Certain Covenants.............  The Indenture contains certain covenants,
                                including limitations under certain conditions
                                on the ability of the Company and its
                                subsidiaries to: (i) incur additional
                                Indebtedness; (ii) incur certain liens; (iii)
                                engage in certain transactions with affiliates;
                                (iv) make certain restricted payments; (v) agree
                                to payment restrictions affecting subsidiaries;
                                (vi) engage in unrelated lines of business; or
                                (vii) engage in mergers, consolidations or the
                                transfer of all or substantially all of the
                                assets of the Company to another person. In
                                addition, in the event of certain Asset Sales
                                (as defined), the Company will be required to
                                use the proceeds to reinvest in the Company's
                                business, to repay certain debt or to offer to
                                purchase Notes at 100% of the principal amount
                                thereof, plus accrued and unpaid interest, if
                                any, thereon, plus Liquidated Damages, if any,
                                to the date of purchase. See "Description of
                                Notes--Certain Covenants."

Risk Factors..................  For a discussion of certain factors that should
                                be considered in connection with an investment

                                 RISK FACTORS

     Prospective investors should carefully consider the factors set forth under
"Risk Factors," as well as the other information set forth in this Prospectus
before tendering the Old Notes in exchange for the New Notes.

SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE INDEBTEDNESS

     The Company has a substantial amount of debt. At September 30, 1997, after
giving effect to the Initial Offering of the Notes and the application of the
net proceeds therefrom, the aggregate consolidated debt of the Company was
approximately $129.9 million, resulting in total debt as a percentage of total
capitalization of 81%. See "Capitalization."

     The degree to which the Company is leveraged could have important
consequences to holders of the Notes, including the following: (i) the Company's
ability to obtain additional financing in the future for refinancing
indebtedness, acquisitions, working capital, capital expenditures or other
purposes may be impaired; (ii) funds available to the Company for its operations
and general corporate purposes or for capital expenditures will be reduced
because a substantial portion of the Company's consolidated cash flow from
operations will be dedicated to the payment of the principal and interest on its
indebtedness; (iii) the Company may be more highly leveraged than certain of its
competitors, which may place it at a competitive disadvantage; (iv) the
agreements governing the Company's long-term indebtedness (including
indebtedness under the Notes) and bank loans contain certain restrictive
financial and operating covenants; (v) an event of default, which is not cured
or waived, under financial and operating covenants contained in the Company's or
its subsidiaries' debt instruments, including the Indenture, could occur and
have a material adverse effect on the Company; (vi) the Company may be more
vulnerable to a downturn in general economic conditions; and (vii) certain of
the borrowings under debt agreements of the subsidiaries have floating rates of
interest, which causes the Company and its subsidiaries to be vulnerable to
increases in interest rates.

     The terms of the Indenture allow for the incurrence of additional
Indebtedness (as defined). Except as set forth below, the incurrence of
additional Indebtedness is limited by certain conditions, including compliance
with a Consolidated Coverage Ratio (as defined). The Company and its
subsidiaries may incur, issue or guarantee certain other additional Indebtedness
without regard to compliance with the Consolidated Coverage Ratio or any other
financial ratio or covenant in the Indenture. See "Description of Notes." If the
Company or any of its subsidiaries incurs additional Indebtedness, whether for
acquisitions, investment in its business or other general corporate purposes,
the Company's leverage could increase, which in turn could make the Company more
susceptible to the factors described above.

     The ability of the Company to make principal and interest payments, or to
refinance indebtedness, including the Notes, will depend on the Company's and
its subsidiaries' future operating performance and cash flow, which are subject
to prevailing economic conditions and interest rate levels, in addition to
financial, competitive, business and other factors affecting the Company and its
subsidiaries, many of which are beyond the Company's control. See "Description
of Other Indebtedness."

     Because the Company's business is conducted through its subsidiaries, the
Company's ability to make scheduled payments of principal and interest on its
indebtedness, including the Notes, will depend on the future operating
performance and cash flows of its subsidiaries and on the ability of the
Company's subsidiaries to pay dividends or make loans to the Company.  See
"Special Note Regarding Forward-Looking Statements."

RANKING OF NOTES

     The Notes and the Guarantees issued by the Guarantors are effectively
subordinated to all existing and future secured indebtedness of the Company and
the Guarantors, including, but not limited to, the loans outstanding under the
Revolving Credit Facility, the DSN Loans, the TES Revolving Facility, TES
Capitalized Leases, the IEC Capitalized Leases, the CM Loan, the CM Equipment
Financing and the IEC Equipment Financing (each as defined). As of

                                      -17-
<PAGE>
 
November 30, 1997, and after giving effect to the application of the net
proceeds received from the Initial Offering, the Company had approximately $23.3
million of secured indebtedness. See "Description of Other Indebtedness."

FRAUDULENT CONVEYANCE CONSIDERATIONS

     Holders of the Notes have a direct claim on the assets of the Guarantors
pursuant to the Guarantees. However, each Guarantor's guarantee of the
obligations of the Company under the Notes may be subject to review under
relevant federal and state fraudulent conveyance statutes in a bankruptcy,
reorganization or rehabilitation case or similar proceeding or a lawsuit by, or
on behalf of, unpaid creditors of such Guarantors. If a court were to find under
relevant fraudulent conveyance statutes that, at the time the Notes were issued,
(a) a Guarantor guaranteed the Notes with the intent of hindering, delaying or
defrauding current or future creditors or (b)(i) a Guarantor received less than
reasonably equivalent value or fair consideration for guaranteeing the Notes and
(ii)(A) was insolvent or was rendered insolvent by reason of such Guarantee, (B)
was engaged, or about to engage, in a business or transaction for which its
assets constituted unreasonably small capital, (C) intended to incur, or
believed that it would incur, obligations beyond its ability to pay as such
obligations matured (as all of the foregoing terms are defined in, or
interpreted under, such fraudulent conveyance statutes) or (D) was a defendant
in an action for money damages, or had a judgment for money damages docketed
against it (if, in either case, after final judgment, the judgment is
unsatisfied), such court could avoid or subordinate such guarantee of the Notes
to presently existing and future indebtedness of such Guarantor and take other
action detrimental to the holders of the Notes, including, under certain
circumstances, invalidating such guarantee of the Notes.

     The measure of insolvency for purposes of the foregoing considerations will
vary depending upon the federal or state law that is being applied in any such
proceeding. Generally, however, a Guarantor would be considered insolvent if
either (i) the fair market value (or fair saleable value) of its assets is less
than the amount required to pay the probable liability on its total existing
indebtedness and liabilities (including contingent liabilities) as they become
absolute and mature or (ii) it is incurring obligations beyond its ability to
pay as such obligations mature or become due.

RESTRICTIVE COVENANTS

     The Indenture contains numerous restrictive covenants which limit the
discretion of management of the Company with respect to certain business
matters. However, the Indenture does not prohibit the incurrence of additional
Indebtedness by the Company, subject to certain conditions. In addition, the
Revolving Credit Facility contains financial covenants that require the Company
to meet certain financial ratios and tests and provides that a change of control
(as defined in the Revolving Credit Facility) constitutes an event of default.
Should the Company be unable to comply with the financial or other restrictive
covenants under the Revolving Credit Facility at any time in the future, there
can be no assurance that the lender would agree to any necessary amendments or
waivers. The ability of the Company to comply with such provisions of the
Revolving Credit Facility may be affected by events beyond its control. A
failure to comply with the obligations contained in the Revolving Credit
Facility, if not cured or waived, could have a material adverse effect upon the
Company and the ability to meet its obligations, including obligations with
respect to the Notes, and could permit acceleration of the related indebtedness
and acceleration of indebtedness of other instruments, including the Notes, that
contain cross-default provisions. See "Description of Other Indebtedness" and
"Special Note Regarding Forward-Looking Statements."

REPURCHASE OF NOTES AND ACCELERATION OF INDEBTEDNESS UPON CHANGE OF CONTROL

     Upon the occurrence of a Change of Control of LSB or the Company, the
Company will be required to make an offer to repurchase the Notes at a price
equal to 101% of the principal amount thereof, plus accrued and unpaid interest,
if any, plus Liquidated Damages, if any, to the date of repurchase. Certain
events involving a Change of Control could result in acceleration of the
Revolving Credit Facility and other indebtedness of the Company or its
subsidiaries that may be incurred in the future. There can be no assurance that
the Company will have sufficient resources to repurchase the Notes in the event
it becomes obligated to do so, particularly in the event of acceleration of, or
the need

                                      -18-
<PAGE>
 
to comply with repurchase obligations with respect to, other indebtedness. The
failure to repurchase all of the tendered Notes in the event of a Change of
Control constitutes an event of default under the Indenture which may result in
the acceleration of the maturity of the Notes. See "Description of Notes--
Certain Covenants--Repurchase of Notes at the Option of the Holder Upon a Change
of Control," "--Events of Default and Remedies,"  "Security Ownership of Certain
Beneficial Owners and Management" and "Special Note Regarding Forward-Looking
Statements."

SENSITIVITY TO ECONOMIC CYCLES; AVAILABILITY AND PRICING OF RAW MATERIALS

     A significant percentage of the Company's sales is affected by such
cyclical factors as interest rates, inflation, and the costs of certain raw
materials. Anhydrous ammonia, which is purchased from unrelated third parties,
represents the primary component in the production of most of the products of
the Chemical Business. The primary material utilized in anhydrous ammonia
production is natural gas, and fluctuations in the price of natural gas have a
significant effect on the cost of anhydrous ammonia. The Company's Chemical
Business has contracts with two suppliers of anhydrous ammonia to provide the
Chemical Business with all of its anhydrous ammonia requirements. If for any
reason the Chemical Business is unable to purchase anhydrous ammonia in
sufficient quantities to produce its product requirements, the lack of
availability would have a material effect on the Company. During 1994, 1995,
1996, and 1997, there were substantial increases in the price for anhydrous
ammonia. During each of these periods, the Company's Chemical Business was
unable to increase its sales prices to cover all of the higher anhydrous ammonia
costs incurred by the Company, and in the future the Company may not be able to
pass along to its customers the full amount of increases in anhydrous ammonia
costs. Accordingly, the Company's results of operations and financial condition
have in the past been, and may in the future be, adversely affected by cost
increases of raw materials, including anhydrous ammonia. The Company is not able
to predict, as of the date of this Prospectus, what impact, if any, will result
to the Company and the Company's earnings if the price of anhydrous ammonia
continues at or near current levels, which are high on a historical basis, or if
the price of anhydrous ammonia continues to increase further. See "Business--
Chemical Business--Seasonality" and "--Raw Materials," "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and "Special Note
Regarding Forward-Looking Statements."

DSN PLANT DESIGN ISSUES

     The Company's concentrated nitric acid plant, the DSN Plant, located at the
El Dorado Facility, encountered certain mechanical and design problems
associated with the plant's construction and installation. As a result of such
problems, production at the DSN Plant was limited to 170 tons per day (60% of
its stated capacity of 285 tons per day assuming 338 days of annual production)
during the twelve months ended September 30, 1997.  Management implemented
certain corrective actions. Since completing the corrective actions during
October 1997, the DSN Plant is currently operating at approximately 260 tons per
day. Although the Company believes that it has corrected the mechanical and
design problems at the DSN Plant, there are no assurances that the DSN Plant can
sustain production at current levels. See "Summary-The Company-The DSN Plant,"
"Business--Chemical Business--DSN Plant" and "Special Note Regarding Forward-
Looking Statements."

COMPETITION

     Substantially all of the markets in which the Company participates are
highly competitive with respect to product quality, price, design innovations,
distribution, service, warranties, reliability and efficiency. Certain of the
Company's competitors have greater financial, marketing and other resources and
brand awareness than the Company. Competitive factors could require price
reductions or increased spending on product development, marketing and sales
that would adversely affect the Company's operating results. See "Business--
Competition" and "Special Note Regarding Forward-Looking Statements."

                                      -19-

CONTROLLING INTERESTS

     Jack E. Golsen, Chairman of the Board and President of LSB and the Company,
members of his immediate family (spouse and children), entities owned by them
and trusts for which they possess voting or dispositive power as trustee (the
"Golsen Group") owned as of November 30, 1997, an aggregate of 3,048,725 shares
of LSB's common stock and 20,000 shares of LSB's voting preferred stock, which
together represent approximately 24% of the issued and outstanding voting
securities of LSB as of such date. The Golsen Group has options, exercisable
within 60 days, rights and other convertible preferred stock which allow its
members to acquire an additional 866,843 shares of LSB's common stock. If the
Golsen Group were to acquire the additional 866,843 shares of common stock, the
Golsen Group would, in the aggregate, own 3,915,568 shares of LSB common stock,
or approximately 28.7% of the issued and outstanding shares of voting securities
of LSB. Thus, the Golsen Group may be considered to effectively control LSB.
Because LSB owns all of the issued and outstanding voting securities of the
Company, the Golsen Group may be considered to effectively control the Company.
See "Security Ownership of Certain Beneficial Owners and Management." A
corporation controlled by Jack E. Golsen has an outstanding proposal to acquire
a new series of convertible preferred stock of LSB. If this transaction were to
occur as proposed, the Golsen Group's percentage of voting securities of LSB
would increase substantially.

CONTROL BY AND POSSIBLE CONFLICTS OF INTEREST WITH LSB

     The Company is a wholly owned subsidiary of LSB, and the Board of Directors
and executive officers of the Company are comprised of various executive
officers and directors of LSB. As a result, LSB possesses the power to direct,
or cause the direction of, the management and policies of the Company.

     LSB and other companies affiliated with LSB may, directly or indirectly,
compete with the Company. The potential for conflicts of interest exist between
the Company and affiliated parties for future business opportunities that may
not be presented to the Company. See "Certain Relationships and Related
Transactions."

DEPENDENCE ON KEY PERSONNEL

     The Company relies heavily on Jack E. Golsen, Chairman of the Board and
President of the Company. Although the Company believes it has an experienced
and capable management team, the loss of Mr. Golsen's services may have a
material adverse impact on the Company. LSB, the parent of the Company, has an
employment agreement and severance agreement with Mr. Golsen and certain other
executive officers of the Company. See "Management--Employment Contracts;
Termination of Employment and Change in Control Agreements."

ENVIRONMENTAL MATTERS

     The Company is subject to extensive federal, state and local environmental
laws, rules, regulations and risks relating to pollution, the protection of the
environment or the release or disposal of hazardous or toxic materials
("Environmental Laws"). In particular, the manufacture and distribution of
chemical products are activities which entail environmental risks and impose
obligations under the Environmental Laws, many of which provide for substantial
fines and criminal sanctions for violations, and there can be no assurance that
material costs or liabilities will not be incurred by the Company in complying
with such laws or in paying fines or penalties for violation of such laws. The
Environmental Laws and enforcement policies thereunder relating to the Chemical
Business have in the past resulted, and could in the future result, in
penalties, cleanup costs, or other liabilities relating to the handling,
manufacture, use, emission, discharge or disposal of pollutants or other
substances at or from the Company's facilities or the use or disposal of certain
of its chemical products. Potentially significant expenditures could be required
in order to comply with the Environmental Laws, including for additional site or
operational modifications at the El Dorado Facility. In addition, the Chemical
Business currently is subject to certain civil lawsuits and administrative
consent orders relating to various environmental matters which could result in
substantial liability for the Company. There can be no assurance

                                      -20-
<PAGE>
 
that such matters will not have a material adverse effect on the Company's
operations or financial condition. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Chemical Business," "Business--
Chemical Business," "--Environmental Matters" and "--Legal Proceedings."

ANTITRUST ISSUES

     The Company's Chemical Business is a defendant in certain pending civil
antitrust lawsuits. See "Business--Legal Proceedings." Discovery has only
recently begun in the pending lawsuits, and, as a result, it is impossible to
access the likelihood of the Chemical Business' success in these lawsuits. For
several years, certain members of the explosives industry have been the focus of
grand jury investigations being conducted by the U.S. Department of Justice (the
"DOJ") in connection with antitrust allegations involving price fixing. Certain
explosives companies, other than the Company, including all the Company's major
competitors, and individuals employed by certain of those competitors, were
indicted and have pled guilty to criminal antitrust violations. The guilty pleas
have resulted in a total of nearly $40 million in criminal fines. In connection
with the grand jury investigation, the Company's Chemical Business received and
has complied with two document subpoenas, certain of the Company's Chemical
Business employees have been interviewed by the DOJ under grants of immunity
from prosecution, and certain of the Company's Chemical Business employees have
testified under subpoena before a grand jury under grants of immunity in
connection with the investigation. The Company believes that it has cooperated
fully with the government's investigation. Recently, the Company was informed by
an official of the DOJ that it was not currently a target of the above
investigation or of any grand jury investigating criminal antitrust activity in
the explosives or ammonium nitrate industries.

     The Company intends to vigorously defend itself in the lawsuits.  There are
no assurances that the lawsuits or the investigation will not have a material
adverse effect on the Company.

ABSENCE OF A PUBLIC MARKET COULD ADVERSELY AFFECT THE VALUE OF THE NOTES

     The Old Notes were issued to, and the Company believes are currently owned
by, a relatively small number of beneficial owners.  Prior to the Exchange
Offer, there has not been a public market for the Old Notes.  The Old Notes have
not been registered under the Securities Act and will be subject to restrictions
on transferability to the extent that they are not exchanged for New Notes by
holders who are entitled to participate in this Exchange Offer. The holders of
Old Notes (other than any such holder that is an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act) who are not eligible to
participate in the Exchange Offer are entitled to certain registration rights,
and the Company is required to file a Shelf Registration Statement with respect
to such Old Notes. The New Notes will constitute a new issue of securities with
no established trading market.  The Company does not intend to list the New
Notes on any national securities exchange or seek the admission thereof to
trading in the National Association of Securities Dealers Automated Quotation
System.  The Initial Purchaser has advised the Company that it currently intends
to make a market in the New Notes, but the Initial Purchaser is not obligated to
do so and may discontinue such market making at any time.  In addition, such
market making activity will be subject to the limits imposed by the Securities
Act and the Exchange Act and may be limited during the Exchange Offer and the
pendency of any Shelf Registration Statement.  Accordingly, there can be no
assurance that an active public or other market will develop for the New Notes
or as to the liquidity of the trading market for the New Notes.  If a trading
market does not develop or is not maintained, holders of the New Notes may
experience difficulty in reselling the New Notes or may be unable to sell them
at all.  If a market for the New Notes develops, any such market may be
discontinued at any time.

     If a public trading market develops for the New Notes, future trading
prices of such securities will depend on many factors including, among other
things, prevailing interest rates, the Company's results of operations and the
market for similar securities.  Depending on prevailing interest rates, the
market for similar securities and other factors, including the financial
condition of the Company, the New Notes may trade at a discount from their
principal amount.

                                      -21-
<PAGE>
 
FAILURE TO FOLLOW EXCHANGE OFFER PROCEDURES COULD ADVERSELY AFFECT HOLDERS

     Issuance of the New Notes in exchange for the Old Notes pursuant to the
Exchange Offer will be made only after a timely receipt by the Company of such
Old Notes, a properly completed and duly executed Letter of Transmittal or
Agent's Message (as defined) and all other required documents.  Therefore,
holders of the Old Notes desiring to tender such Old Notes in exchange for New
Notes should allow sufficient time to ensure timely delivery. The Company is
under no duty to give notification of defects or irregularities with respect to
the tenders of Old Notes for exchange.  Old Notes that are not tendered or are
tendered but not accepted will, following the consummation of the Exchange
Offer, continues to be subject to the existing restrictions upon transfer
thereof, and, upon consummation of the Exchange Offer, certain registration
rights under the Registration Rights Agreement will terminate.  In addition, any
holder of Old Notes who tenders in the Exchange Offer for the purpose of
participating in a distribution of the New Notes may be deemed to have received
restricted securities, and if so, will be required to comply with the
registration  and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives New
Notes for its own account in exchange for Old Notes, where such Old Notes were
acquired by such broker-dealer as result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes.  See "Plan of Distribution."  To
the extent that Old Notes are tendered and accepted in the Exchange Offer, the
trading market for untendered and tendered but unaccepted Old Notes could be
adversely affected.  See "The Exchange Offer."


                                USE OF PROCEEDS

     The Exchange Offer is intended to satisfy certain Company obligations under
the Registration Rights Agreement.  The Company will not receive any cash
proceeds from the issuance of the New Notes offered hereby. In consideration for
issuing the New Notes contemplated in this Prospectus, the Company will receive
Old Notes in like principal amount, the form and terms of which are the same as
the form and terms of the New Notes (which replace the Old Notes), except as
described herein.

     The proceeds from the Initial Offering were approximately $105 million
before deducting commissions, Initial Purchaser's discounts, and estimated
expenses thereof.  After deducting discounts and commissions to the Initial
Purchaser, but before deducting other expenses, the net proceeds to the Company
from the Initial Offering were $101.85 million.  The net proceeds from the
Initial Offering were used to (i) repay approximately $53.2 million of
borrowings, interest and prepayment fees to retire the loans to the Company's
Chemical Business from John Hancock Mutual Life Insurance Company and others
(the "John Hancock Loan"); (ii) reduce by approximately $38.6 million amounts
outstanding under the revolving credit facilities with respect to the Chemical
Business and the Climate Control Business; and (iii) fund a loan to the
Company's parent, LSB, of $10 million.  See "Description of Notes - Certain
Covenants - LSB Note."

CHEMICAL BUSINESS

     The Company has grown the Chemical Business through the expansion of its El
Dorado Facility and the acquisition of new agricultural distribution centers in
key geographical markets that are freight logical to the El Dorado Facility.
During the period from December 31, 1993, through September 30, 1997, the net
investment in assets of the Chemical Business was increased from $76.9 million
to  $134.6  million primarily due to the construction of additional capacity to
benefit future periods.

                                      -26-
<PAGE>
 
     Beginning in 1994, the results of operations of the Chemical Business have
been adversely impacted by the high cost of anhydrous ammonia. From its most
recent cyclical low in 1986 through 1993, the average Gulf Coast price (the
"Spot Price") of anhydrous ammonia was approximately $100 per ton. During 1994
and in each of the years since, a tightness in supply developed which resulted
in an increase in the Spot Price of anhydrous ammonia to an average of
approximately $195 per ton. The Company believes that the tightness in supply of
anhydrous ammonia that emerged in 1994 was a result of increased industrial
usage as the U.S. economy grew, a net consolidation of the domestic capacity and
a disruption in supply coming from the former Soviet Union. Although prices for
anhydrous ammonia vary considerably from month to month, the annual average
price has remained high for each of the last three years. The Company currently
purchases approximately 220,000 tons of anhydrous ammonia per year under two
contracts, both effective as of January 1, 1997. The Company's purchase price of
anhydrous ammonia under these contracts can be higher or lower than the Spot
Price of anhydrous ammonia. The higher prices have been partially passed on to
customers; however, the entire cost increase could not be offset resulting in
lower gross profit margins during each of the periods since the increase. The
Company believes there is approximately 2 million tons of additional capacity
being constructed in the western hemisphere scheduled for completion in 1998 and
1999. The Company believes this additional capacity may contribute to a decline
in the market price of anhydrous ammonia. See "Special Note Regarding Forward-
Looking Statements."

     During 1994, the Company undertook construction of the DSN Plant. The DSN
Plant began operations in 1995, but due to certain mechanical and design
problems, production of concentrated nitric acid during the twelve months ended
September 30, 1997, was limited to an average of 170 tons per day, assuming 338
days of annual production, or 60% of the stated capacity of 285 tons per day.
The limitations on production resulted in significant fixed costs being expended
as period costs during the second half of 1996, and the first half of 1997,
rather than being absorbed as cost of product being produced and sold. In
addition, significant amounts were expended for engineering, consulting, and
other costs to bring the DSN Plant up to the stated capacity. During the annual
maintenance turnaround in September 1997, management implemented corrective
actions which it believes will now allow the DSN Plant to operate at its stated
capacity, depending upon customer specifications, and to fully absorb the costs
and produce a quality product. See "Special Note Regarding Forward-Looking
Statements."  In early October 1997, the DSN Plant was restarted and is
currently operating at approximately 260 tons per day due to customer
specifications.  See "Summary-The Company-The DSN Plant."

     After the initial start up of the DSN Plant, certain residents of El
Dorado, Arkansas, and the ADPC&E (as defined) alleged that the El Dorado
Facility's air emissions were in violation of its existing permit requirements.
As a result, the Chemical Business entered into certain agreements with the
ADPC&E, including, in 1995, an administrative order which has since been
amended, and which imposed certain requirements on, and assessed penalties
against, the Company. See "Business--Environmental Matters." In addition,
certain lawsuits were filed by plaintiffs living in the El Dorado, Arkansas,
community. See "Business--Legal Proceedings." In order to address the ADPC&E's
concerns, and to defend itself in these lawsuits, significant expenditures were
made for consultants, lawyers, and other related fees and expenses, as well as
for significant capital improvements to the air emission control equipment at
the El Dorado Facility. A substantial portion of the litigation-related costs
are not expected to reoccur. Furthermore, although these expenses were absorbed
by the Company as they were incurred, the Company's EIL Insurance (as defined)
has reimbursed the Company $405,000 of its past legal fees and expenses relating
to the pending litigation (after taking into account the amount of the retention
under the EIL Insurance) and has agreed to pay such future fees and expenses
which may be incurred, subject to a reservation of rights regarding one of the
lawsuits. See "Business--Legal Proceedings."

     During July 1997, a subsidiary of the Company entered into an agreement
with Bayer Corporation whereby the Company's subsidiaries would act as agent to
construct a nitric acid plant located within Bayer's Baytown, Texas chemical
plant complex. This plant, when constructed, will be operated by the Company's
subsidiary and will supply nitric acid for Bayer's polyurethane units under a
long-term supply contract. Management estimates that, after the initial startup
phase of operations at the plant, at full production capacity based on terms of
the Bayer Agreement and on current market conditions, the plant should generate
approximately $50 million in annual revenues. Construction is scheduled to be
completed by the end of 1998.  See "Special Note Regarding Forward-Looking
Statements."

     The Chemical Business' Australian subsidiary ("TES") results of operations
have been adversely affected due to the recent economic developments in certain
countries in Asia. These economic developments in Asia have had a negative
impact on the mining industry in Australia which TES services. If these adverse
economic conditions in Asia continue for an extended period of time, such could
have an adverse effect on the Company's consolidated results of operations for
1998. See "Special Note Regarding Forward-Looking Statements."

CLIMATE CONTROL

     The Climate Control Business maintains two modern, flexible manufacturing
and design facilities located in Oklahoma City, Oklahoma. The Climate Control
Business' two principal product lines are manufactured and sold through two
operating subsidiaries: International Environmental Corporation ("IEC"), which
manufactures and markets hydronic fan coil units, and Climate Master, Inc.
("CM"), which manufactures and markets water source heat pumps, geothermal water
source heat pumps, and packaged terminal air conditioners.

     The Climate Control Business has generated an operating profit in each year
from 1992 through 1996. However, during that period, CM sustained consistent
operating losses which were more than offset by profitability at IEC.

     CM's profitability was adversely affected by a sharp decline in the primary
market for its products sold to the new office construction market, which was
adversely affected by the passage of the Tax Reform Act of 1986. As a result,
the total sales of water source heat pumps in the U.S. plunged from 150,000
units per year in 1986 to 71,000 units per year in 1992. CM's sales revenue
decreased from a high of $47.8 million in 1986 to a low of $21.8 million in
1992.

     Due to significant changes in its primary market, CM implemented a strategy
of diversification. Several new markets were targeted, and new products were
introduced. CM entered the original equipment manufacturer ("OEM") business,
introduced a new line of packaged terminal air conditioners and new rooftop
water source heat pumps, entered the "shared energy savings" market (which
primarily sells highly efficient water source heat pumps to retrofit large
government installations), and emphasized and expanded the residential
geothermal water source heat pump business. In addition, a new management team
was recruited, and CM's operations were reorganized.

     These actions were implemented over the last two years and began to improve
operating performance in 1997. As a result of these actions, CM's sales
increased from $27.5 million to $37.5 million and its operating losses have
narrowed from $3.0 million to $0.1 million for the nine months ended September
30, 1996, and September 30, 1997, respectively.

RESULTS OF OPERATIONS

NINE MONTHS ENDED SEPTEMBER 30, 1997, COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1996

Net Sales

     Consolidated net sales for the nine months ended September 30, 1997, were
$200.4 million, compared to $195.4 million for the first nine months of 1996, an
increase of $5.0 million. This increase in sales resulted from increased sales
in the Climate Control Business of $11.2 million, primarily due to increased
sales of CM's heat pumps partially offset by decreased sales in the Chemical
Business of $6.3 million primarily due to reduced sales of the Company's 
wholly-owned Australian subsidiary, Total Energy Systems Limited ("TES"), due to
expiration of certain customer contracts.

Gross Profit

     Gross profit increased $1.3 million and was 19.3% of net sales for the
first nine months of 1997, compared to 19.1% of net sales for the first nine
months of 1996. The gross profit increase was primarily attributable to
increased absorption of costs due to higher production volumes and focus on
sales of more profitable product lines in the Climate Control Business. This
improvement was offset by higher production costs in the Chemical Business due
to (i) the higher cost of anhydrous ammonia which was only partially passed on
in the form of higher selling prices, (ii) unabsorbed overhead costs caused by
downtime related to modifications made to resolve problems associated with
mechanical failures and (iii) environmental matters at the Chemical Business'
primary manufacturing plant. These increased costs

                                      -28-
<PAGE>
 
in 1997 were partially offset by a reduction in cost of sales of $2.1 million
through recapture of manufacturing variances of the Chemical Business in the
form of business interruption insurance settlements.

Selling, General and Administrative Expense

     Selling, general and administrative ("SG&A") expenses, as a percent of net
sales, were 14.0% and 12.4% in the nine month periods ended September 30, 1997,
and 1996, respectively. The increase, as a percent of sales, was approximately
the same for the Chemical and Climate Control Businesses. The increase in the
Chemical Business was the result of an increased provision for one uncollectible
account receivable of approximately $350,000 and increased professional fees of
approximately $200,000, primarily related to environmental matters, compounded
by lower sales in this business. The increase in the Climate Control Business
was due to increased administrative and selling expenses as a percent of sales
in the heat pump product line associated with the implementation of a new
marketing plan for CM.

Interest Expense

     Interest expense for the Company, before deducting capitalized interest,
was approximately $7.7 million during the nine months ended September 30, 1997,
compared to approximately $6.3 million during the nine months ended September
30, 1996. During the first nine months of 1997 and 1996, $1.1 million and $1.8
million, respectively, of interest expense was capitalized in connection with
construction of the DSN Plant. The 1997 increase of $1.4 million before the
effect of capitalization primarily resulted from increased borrowings needed to
support capital expenditures, higher inventory balances and to meet the
operational requirements of the Company.

Net Income

     The Company had net income of $2.8 million in the first nine months of 1997
compared to net income of $5.7 million in the nine months ended September 30,
1996. The decreased profitability of $2.9 million was primarily due to the
factors discussed above.

YEAR ENDED DECEMBER 31, 1996, COMPARED TO YEAR ENDED DECEMBER 31, 1995

Net Sales

     Consolidated net sales for 1996 were $255.3 million, compared to $220.7
million for 1995, an increase of $34.6 million or 15.6%. This increase resulted
principally from: (i) increased sales in the Climate Control Business of $5.3
million, primarily due to the implementation of CM's diversification strategy
and the efforts of its new management, both as described above, and (ii)
increased sales in the Chemical Business of $29.3 million. The Chemical Business
had increases of approximately $7.0 million in sales of agricultural products
and approximately $6.0 million in sales of industrial products. These sales
increases involved both volume and price increases as higher raw material costs
were passed through to customers to the extent possible. Additionally, TES, the
Company's subsidiary located in Australia and New Zealand, had an increase in
sales of $16.0 million due to an expanded customer base.

Gross Profit

     Gross profit decreased $0.4 million and was 18.6% of net sales for 1996,
compared to 21.7% of net sales for 1995. The gross profit percentage declined in
both the Chemical and Climate Control Businesses. The gross profit of the
Chemical Business was adversely affected due to the continued high cost of
anhydrous ammonia as discussed above and higher production costs due to
unabsorbed overhead costs resulting from excessive downtime at the Chemical
Business' El Dorado Facility related to modifications made to install air
emissions abatement equipment and resolve problems associated with mechanical
and design problems at the DSN Plant. See "Business--Environmental Matters." The
Climate Control Business' gross profit decreased as a percentage of net sales
due to decreased absorption of costs resulting from lower production volumes in
certain product lines and a less favorable product mix.

                                      -29-
<PAGE>
 
Selling, General and Administrative Expense

     SG&A, as a percent of net sales, was 13.0% in 1996 and 13.7% in 1995.
Climate Control Business SG&A expenses were approximately the same in 1996 as
1995, and net sales increased by 6.3% resulting in a lower percentage of SG&A to
sales. SG&A of the Chemical Business, as a percent of sales, was consistent with
sales increases, therefore generating no change as a percent of net sales. The
Chemical Business also incurred approximately $450,000 in 1996 for legal and
consulting fees for environmental and legal matters relating to the El Dorado
Facility's air emissions. See "Business--Environmental Matters." Also in 1996,
the Chemical Business expended approximately $1.0 million to increase its
provision for one uncollectible account receivable.

Interest Expense

     Interest expense for the Company, before deducting capitalized interest,
was $8.7 million during 1996, compared to $8.5 million during 1995. During 1996,
$2.4 million of interest expense was capitalized in connection with construction
of the DSN Plant, compared to $1.4 million in 1995.

Net Income

     The Company had net income of $5.8 million in 1996 compared to net income
of $5.9 million in 1995. Although 1996 consolidated net sales increased, the
consolidated gross profit declined and SG&A increased due to the factors
discussed above.

YEAR ENDED DECEMBER 31, 1995, COMPARED TO YEAR ENDED DECEMBER 31, 1994

Net Sales

     Consolidated net sales for 1995 were $220.7 million, compared to $201.5
million for 1994, an increase of $19.2 million or 9.5%. This sales increase
resulted principally from: (i) increased sales in the Climate Control Business
of $13.9 million, primarily due to increased sales in the fan coil segment of
the Climate Control Business and to increased sales in geothermal water source
heat pumps related to certain governmental projects and (ii) increased sales in
the Chemical Business of $5.3 million, which were primarily attributable to
higher anhydrous ammonia costs being passed through to customers and increased
sales of $2.5 million at TES due to the addition of new customers.

Gross Profit

     Gross profit increased $5.0 million and was 21.7% of net sales for 1995,
compared to 21.3% of net sales for 1994. Although the Chemical Business' gross
profit increased by $0.5 million, the gross margin was adversely affected due to
the continued high cost of anhydrous ammonia as discussed above. The gross
profit of the Climate Control Business increased approximately $4.5 million due
to increased sales volume and improved absorption of fixed costs.

Selling, General and Administrative Expense

     SG&A expenses increased $2.6 million in 1995 compared to 1994. As a percent
of net sales SG&A expenses were 13.7% in 1995 and 13.8% in 1994. SG&A, as a
percentage of sales, remained consistent in both the Chemical and Climate
Control Businesses.

Interest Expense

     Interest expense for the Company, before deducting capitalized interest,
was $8.5 million during 1995, compared to $6.6 million during 1994. During 1995,
$1.4 million interest expense was capitalized in connection with construction of
the DSN Plant compared to $0.5 million in 1994. The increase in interest expense
primarily resulted

                                      -30-
<PAGE>
 
from increased borrowings. The increased borrowings were necessary to support
capital expenditures, higher inventory levels, higher accounts receivable
balances and to meet the operational requirements of the Company. See "--
Liquidity and Capital Resources."

Net Income

     The Company had net income of $5.9 million in 1995 compared to net income
of $5.4 million in 1994. This improvement in 1995 was primarily attributable to
increased sales volume with slightly higher profit margins offset by increased
interest expense and SG&A as discussed above.

LIQUIDITY AND CAPITAL RESOURCES

     Historically, the Company's primary cash needs have been for operating
expenses, working capital and capital expenditures. The Company has financed its
cash requirements primarily through internally generated cash flow and
borrowings under its revolving credit facilities.

     Cash flows from operations before changes in working capital items were
$9.6 million and $12.4 million for the nine months ended September 30, 1997, and
1996, respectively. During the nine months ended September 30, 1997, net cash
flows used in operating activities were $2.0 million while the nine months ended
September 30, 1996, provided net cash flows of $9.6 million. This reduction in
cash flows provided from operations of $11.6 million resulted from lower
earnings of $2.9 million and an increase in working capital of $8.8 million. The
increase in working capital is due primarily to a net decrease in accounts
payable partially due to reduced inventory purchases under a product exchange
agreement and a net reduction in accounts receivable due to slower sales growth
during the first nine months of 1997 compared with the comparable period in
1996.

     Cash flows from operations before changes in working capital items were
$14.3 million and $13.6 million for the year ended December 31, 1996, and 1995,
respectively. During the year ended December 31, 1996, and 1995, net cash
provided by operations were $15.0 million and $10.2 million, respectively. This
increase in cash flows provided from operations was due primarily to an increase
in accounts payable and accrued liabilities of $15.5 million partially offset by
a net increase in accounts receivable of $2.1 million and inventories of $7.7
million resulting from higher sales volume in both the Chemical and Climate
Control Businesses.

     Cash flows from operations before changes in working capital items were
$13.6 million and $13.9 million for the year ended December 31, 1995, and 1994,
respectively. During the year ended December 31, 1995, and 1994, net cash flows
from operations were $10.2 million and $10.1 million, respectively. Cash flows
from operations were impacted by higher levels of accounts receivables due to
greater sales levels in 1995 offset by a net decrease in inventories and
accounts payable compared to 1994.

     The Company made capital expenditures of $18.6 million, $15.9 million and
$14.0 million during the years ended December 31, 1996, 1995, and 1994,
respectively, and $6.0 million for the nine months ended September 30, 1997.
Approximately $6.5 million, $11.2 million, and $11.0 million of expenditures
made during 1996, 1995, and 1994, and $1.3 million of the expenditures made
during the first nine months of 1997 relate directly to the construction, start-
up and subsequent modification of the DSN Plant. The Company expects to make
capital expenditures totaling $6.0 million during 1997 and approximately $8.0
million in 1998.  See "Special Note Regarding Forward-Looking Statements."

     The Company incurred substantial indebtedness in connection with the
Initial Offering. After giving effect to the Initial Offering and application of
the net proceeds therefrom, as of September 30, 1997, the Company's indebtedness
increased from approximately $106.9 million to approximately $129.9 million,
consisting of $105 million of the Notes and $24.9 million under other debt
facilities, including capital leases.

     LSB, certain subsidiaries of LSB that are not subsidiaries of the Company,
and certain subsidiaries of the Company are parties to $65 million revolving
credit facility ("Revolving Credit Facility"). The Revolving Credit Facility is
evidenced by one loan agreement for the Company's subsidiaries that are parties
thereto and separate loan agreements for LSB and its other subsidiaries that are
not subsidiaries of the Company.

     Under the terms of the Revolving Credit Facility, subsidiaries of the
Company may borrow up to $65 million on a revolving basis subject to limitations
based on (i) the amount of eligible receivables and inventory of such
subsidiaries and (ii) the aggregate amount of borrowings under the Revolving
Credit Facility by LSB and certain subsidiaries that are not subsidiaries of the
Company. Under the Revolving Credit Facility, LSB and certain subsidiaries of
LSB that are not subsidiaries of the Company have the right to borrow on a
revolving basis up to $24 million. Any amounts so borrowed by LSB and its
subsidiaries that are not subsidiaries of the Company will reduce the amount
that the subsidiaries of the Company may borrow at any one time under the
Revolving Credit Facility. The Revolving Credit Facility, as it relates to the
subsidiaries of the Company, will be secured by the receivables, inventory,
proprietary rights, general intangibles, books and records and proceeds thereof.
LSB guarantees all of the obligations under the Revolving Credit Facility,
including those of the Company's subsidiaries. The Company guarantees only the
obligations of its subsidiaries under the Revolving Credit Facility, and neither
the Company nor its subsidiaries that are parties to the Revolving Credit
Facility guarantee the obligations of LSB and the other subsidiaries of LSB that
are not subsidiaries of the Company under the Revolving Credit Facility. In
addition, a default by LSB and the other subsidiaries of LSB that are not
subsidiaries of the Company under the Revolving Credit Facility will not be
considered a default of the Company's subsidiaries under the Revolving Credit
Facility. The Revolving Credit Facility will terminate on December 31, 2000,
subject to the automatic renewal for terms of 13 months each thereafter, unless
terminated by either party.

     Borrowings under the Revolving Credit Facility bear an annual rate of
interest at a floating rate based on the lender's prime rate plus 1.5% per annum
or, at LSB's option, on the lender's LIBOR rate plus 3.875% per annum (which
rates are subject to increase or reduction upon achieving specified availability
and adjusted tangible net worth, as defined).

     The Company used a portion of the net proceeds from the Initial Offering to
repay a substantial portion of the unpaid principal due by certain of its
subsidiaries under their current revolving credit facilities. See "Use of
Proceeds." The Company intends to continue to borrow, from time to time, under
its existing revolving credit facilities as the Company may deem appropriate to
finance the working capital requirements of the Company and its subsidiaries. As
of November 30, 1997, and after giving effect to the application of the net
proceeds from the Initial Offering, the Company had availability under the
Revolving Credit Facility of approximately $43.5 million. In addition, as of
November 30, 1997, and after giving effect to the application of the net
proceeds from the Initial Offering, the Company's Australian subsidiary had
availability of approximately US$2.5 million under its revolving credit
facility. See "--Foreign Subsidiary Financing."

     In addition to the Agreements discussed above, as of September 30, 1997,
the Company's wholly-owned subsidiary, DSN Corporation ("DSN"), is a party to
several loan agreements with a financial company (the "Financing Company") for
three projects. At September 30, 1997, DSN had outstanding borrowings of $14.1
million under these loans. The loans have repayment schedules of 84 consecutive
monthly installments of principal and interest. The interest rate on each of the
loans is fixed and range from 8.2% to 8.9%. Annual interest, for the three notes
as a whole, at September 30, 1997, at the agreed to interest rates would
approximate $1.2 million. The loans are secured by the various DSN property and
equipment. The loan agreements require the Company to maintain certain financial
ratios, including tangible net worth requirements.

FOREIGN SUBSIDIARY FINANCING

     The Company's wholly-owned Australian subsidiary, TES, has a revolving
credit working capital facility (the "TES Revolving Facility") with Bank of New
Zealand, Australia, of approximately AUS$8.5 million (approximately

                                      -32-
<PAGE>
 
US$6.4 million). The TES Revolving Facility allows for borrowings based on
specific percentages of qualified eligible assets. Based on the effective
exchange rate at September 30, 1997, approximately US $5.6 million (AUS $7.7
million approximately) was borrowed at September 30, 1997. Such debt is secured
by substantially all the assets of TES, plus an unlimited guarantee and
indemnity from LSB and certain subsidiaries of TES. The interest rate on this
debt is dependent upon the borrowing option elected by TES and had a weighted
average rate of 7.8% at September 30, 1997. TES is in technical noncompliance
with a certain financial covenant contained in the loan agreement involving the
TES Revolving Facility. However, this covenant was not met at the time of
closing of this loan and the Bank of New Zealand, Australia has continued to
extend credit under the Facility. The outstanding borrowing under the TES
Revolving Facility at September 30, 1997, has been classified as due within one
year in the accompanying consolidated financial statements.

     The Company is in negotiations with Bank of New Zealand to amend the TES
Revolving Facility to allow for borrowings up to an aggregate of AUS$11 million
(approximately US$7.9 million). This AUS$11 million will be broken down into
three parts: (i) AUS$6 million revolving working capital facility; (ii) AUS$4.5
million long-term debt facility; and (iii) AUS$0.5 million leasing facility.
There are no assurances that such increase will be implemented.

     Management believes that following the Initial Offering cash flows from
operations, availability under the Company's revolving credit facilities, and
other sources will be adequate to meet its presently anticipated capital
expenditure, working capital, and debt service requirements. There can be no
assurance that the Company's business will generate sufficient cash flow from
operations, or that future financings will be available in an amount sufficient
to enable the Company to service its indebtedness, including the Notes, or to
make necessary capital expenditures, or that any refinancing would be available
on commercially reasonable terms, if at all.  See "Special Note Regarding
Forward-Looking Statements."

                                   BUSINESS

GENERAL

     The Company, a wholly owned subsidiary of LSB, is engaged, through its
subsidiaries, in the manufacture and sale of (i) chemical products for the
explosives, agricultural and industrial acids markets and (ii) a broad range of
hydronic fan coils and water source heat pumps as well as other products used in
commercial and residential HVAC systems. For the twelve months ended September
30, 1997, the Company had net sales of $260.2 million and EBITDA of $21.4
million.

BUSINESS STRATEGY

     The Company is pursuing a strategy of concentrating on businesses and
product lines in niche markets where it can establish a position as a market
leader. The Company believes that it can maximize its long-term profitability by
offering specialized products and value-added services to its customers.  See
"Special Note Regarding Forward-Looking Statements."

     The Chemical Business seeks to maximize profitability by (i) being a low
cost producer, (ii) focusing on a specific geographic area where it can develop
a freight and distribution advantage and establish a leading regional presence,
(iii) offering value added services as a means of building customer loyalty and
(iv) continuing to alter the product mix towards higher margin products. The
Company has developed a geographic advantage in the Texas, Oklahoma, Missouri
and Tennessee agricultural markets by establishing an extensive network of
wholesale and retail distribution centers for nitrogen-based fertilizer tailored
toward regional farming practices and by providing value added services. In its
continued focus toward reducing production costs, the Company undertook
construction of the DSN Plant in 1994. The Company believes that the DSN Plant's
more efficient and improved production of concentrated nitric acid will provide
for a greater volume of third party sales of concentrated nitric acid, a
relatively high margin product. The

                                      -33-
<PAGE>
 
Company has also developed a proprietary line of explosives through a nationally
recognized branded product. Given the nature of the product, the Company
believes its branding strategy, emphasizing quality, safety and reliability,
gives it a competitive advantage over less recognized explosive products.  See
"Special Note Regarding Forward-Looking Statements."

     The Climate Control Business seeks to establish leadership positions in
niche markets by offering extensive product lines, custom tailored products and
proprietary new technologies. Under this focused strategy, the Company has
developed the most extensive line of hydronic fan coils and water source heat
pumps in the U. S. The Company has developed flexible production to allow it to
custom design units for the growing retrofit and replacement markets. The
Company believes that the Climate Control Business is one of the leaders in
commercializing new technology to satisfy increasingly stringent indoor air
quality standards. Products recently developed by the Company include heat pipe
technology for dehumidification, specialty filters for the removal of airborne
particles and gases, ultraviolet light units for bacteria removal and highly
energy efficient dual path heat pump products. The Climate Control Business is a
pioneer in the use of geothermal water source heat pumps in residential
applications. The Company believes that an aging installed base of residential
HVAC systems, coupled with relatively short payback periods of geothermal
systems, will continue to increase demand for its geothermal products in the
residential replacement market.  See "Special Note Regarding Forward-Looking
Statements."

CHEMICAL BUSINESS

General

     The Company's Chemical Business manufactures three principal product lines
that are derived from anhydrous ammonia: (1) fertilizer grade ammonium nitrate
for the agricultural industry, (2) explosive grade ammonium nitrate for the
mining industry and (3) concentrated, blended and mixed nitric acid for
industrial applications. In addition, the Company also produces sulfuric acid
for commercial applications primarily in the paper industry. The Chemical
Business' products are sold in niche markets where the Company believes it can
establish a position as a market leader. See "Special Note Regarding Forward-
Looking Statements."


                               [INSERT DIAGRAM]


The diagram is intended to illustrate the sequence of events through which 
anhydrous ammonia is processed into the Chemical Business' three principal 
product lines. The diagram reveals the following sequence: (1) anhydrous ammonia
is delivered to regular nitric acid plants and concentrated nitric acid plants; 
(2) the regular nitric acid plants utilize a conventional process for the 
manufacture of (a) fertilizer grade ammonium nitrate which is used by ranchers 
and farmers and (b) industrial grade ammonium nitrate for explosive products 
which are used for surface mining, quarries, general construction and highway 
construction; and (3) the concentrated nitric acid plants utilize the DSN 
Process to manufacture concentrated nitric acid and mixes which are used for 
herbicides, plastics, explosives, and pharmaceuticals.

Agricultural Products

     The Chemical Business produces ammonium nitrate, a nitrogen-based
fertilizer, at the El Dorado Facility. In 1996, the Company sold over 190,000
tons of ammonium nitrate fertilizer to farmers, fertilizer dealers and
distributors located primarily in the south central United States.

     Ammonium nitrate is one of several forms of nitrogen-based fertilizers
which include anhydrous ammonia and urea. Although, to some extent, the various
forms of nitrogen-based fertilizers are interchangeable, each has its own
characteristics which produce agronomic preferences among end users. Farmers
decide which type of nitrogen-based fertilizer to apply based on the crop
planted, soil and weather conditions, regional farming practices and relative
nitrogen fertilizer prices.

     The Chemical Business is a major manufacturer of fertilizer grade ammonium
nitrate, which it markets primarily in Texas, Arkansas and the surrounding
regions. This market, which is in close proximity to its El Dorado

                                      -34-
<PAGE>
 
Facility, includes a high concentration of pasture land and row crops which
favor ammonium nitrate over other nitrogen-based fertilizers. The Company has
developed the leading market position in Texas by emphasizing high quality
products, customer service and technical advice. Using a proprietary prilling
process, the Company produces a high performance ammonium nitrate fertilizer
that, because of its uniform size, is easier to apply than many competing
nitrogen-based fertilizer products. The Company believes that its "E-2" brand
ammonium nitrate fertilizer is recognized as a premium product within its
primary market. In addition, the Company has developed long term relationships
with end users through its network of 21 owned and operated wholesale and retail
distribution centers.

Explosives

     The Chemical Business manufactures low density ammonium nitrate-based
explosives, including bulk explosives used in surface mining. In addition, the
Company manufactures and sells a branded line of packaged explosives, used in
construction, quarrying and other applications, particularly where controlled
explosive charges are required. The Company's bulk explosives are marketed
primarily through six Company-owned distribution centers, four of which are
located in close proximity to the customers' surface mines in the coal producing
states of Kentucky, West Virginia, Illinois, and Indiana. Additionally, the
Company, through its Australian subsidiary, manufactures and distributes bulk
and packaged explosives in Australia and New Zealand. The Company emphasizes
value-added customer services and specialized product applications for its bulk
explosives. Most of the sales of bulk explosives are to customers who work
closely with the Company's technical representatives in meeting their specific
product needs. In addition, the Company sells bulk explosives to independent
wholesalers and to other explosives companies. Packaged explosives are used for
applications requiring controlled explosive charges and typically command a
premium price and produce higher margins. The Company believes its Slurry
packaged explosive products are among the most widely recognized in the
industry. Slurry packaged explosive products are sold nationally and
internationally to other explosive companies and end-users.

Industrial Acids

     The Chemical Business manufactures and sells industrial acids, primarily to
the food, paper, chemical and electronics industries. The Company is the leading
supplier to third parties of concentrated nitric acid which is a special grade
of nitric acid used in the manufacture of plastics, pharmaceuticals, herbicides,
explosives, and other chemical products. In addition, the Company produces and
sells regular, blended and mixed nitric acid and a variety of grades of sulfuric
acid. The Company competes on the basis of price and service, including on-time
reliability and distribution capabilities. The Company operates the largest
fleet of tankcars in the concentrated nitric acid industry which provides it
with a significant competitive advantage in terms of distribution costs and
capabilities. In addition, the Company provides inventory management as part of
the value-added services it offers to its customers.

     The Company has identified concentrated nitric acid as a strategic product
line for its Chemical Business due to attractive levels of profitability,
increased diversity of end markets and the ability to compete on a value added
service basis. To support further growth in its nitric acid business, the
Company undertook the construction of the DSN Plant located at the El Dorado
Facility. The DSN Plant uses a newer and more efficient process to produce
concentrated nitric acid directly from anhydrous ammonia, in contrast to the
conventional process which requires the input of regular nitric acid, an
intermediate step, to produce concentrated nitric acid.

DSN Plant

     Since January 1, 1994, the Chemical Business has spent approximately $32.0
million to install the DSN Plant. The DSN Plant began limited operations in
1995, and such limited operations continued due to certain mechanical and design
problems associated with the plant's construction and installation. As a result
of such problems, production at the DSN Plant was limited to approximately 170
tons per day (60% of its stated capacity of 285 tons per day assuming 338 days
of annual production) during the twelve months ended September 30, 1997. In
October 1997, management completed certain corrective actions at the DSN Plant.
As a result of these corrective actions, the DSN Plant has the

                                      -35-
<PAGE>
 
capacity to operate at approximately 285 tons per day. However, due to customer
specifications and inventory constraints, among other things, the DSN Plant has
been operating at approximately 260 tons per day since the corrective actions
were completed. Based on normalized production (assuming 338 days of annual
production) at 260 tons per day, the Company believes that it will be able to
produce concentrated nitric acid at a cost per ton approximately at $65 per ton
lower than at the production levels of 170 tons per day in the prior period.
While the Company will seek to market the additional capacity of concentrated
nitric acid output to commercial markets, there can be no assurance that the
Company will be able to sell all of the additional capacity in this market.
However, to the extent that there is insufficient demand for concentrated nitric
acid, the Company believes it can profitably use the concentrated nitric acid in
the production of mixed and blended acids and ammonium nitrate based fertilizer
and explosives (although at lower margins than if the production were sold as
concentrated nitric acid). See "Summary-The Company-The DSN Plant," "Risk
Factors-DSN Plant Design Issues," "The Company-Chemical Business-DSN Plant" and
"Special Note Regarding Forward-Looking Statements."

EDNC Baytown Plant

     In June 1997, two wholly owned subsidiaries of the Company, El Dorado
Chemical Company ("EDC") and El Dorado Nitrogen Company ("EDNC"), entered into a
series of agreements with Bayer Corporation ("Bayer") (collectively, the "Bayer
Agreement"). Under the Bayer Agreement, EDNC will act as an agent to construct
and, upon completion of construction, will operate a nitric acid plant (the
"EDNC Baytown Plant") at Bayer's Baytown, Texas chemical facility. EDC has
guaranteed the performance of EDNC's obligations under the Bayer Agreement.

     Under the terms of the Bayer Agreement, EDNC is to lease the EDNC Baytown
Plant pursuant to an operating lease from an unrelated third party with an
initial lease term of ten years from the date on which the EDNC Baytown Plant
becomes fully operational. Bayer will purchase from EDNC all of its requirements
for nitric acid to be used by Bayer at its Baytown, Texas facility for ten years
from the date on which the EDNC Baytown Plant becomes fully operational. EDNC
will purchase from Bayer its requirements for anhydrous ammonia for the
manufacture of nitric acid as well as utilities and other services. Subject to
certain conditions, EDNC will be entitled to sell the amount of nitric acid
manufactured at the EDNC Baytown Plant which is in excess of Bayer's
requirements to third parties. The Bayer Agreement provides that Bayer will make
certain net monthly payments to EDNC which will be sufficient for EDNC to
recover all of its costs plus a profit. Upon expiration of the initial ten-year
term from the date the EDNC Baytown Plant becomes operational, the Bayer
Agreement may be renewed for up to six renewal terms of five years each;
however, prior to each renewal period, either party to the Bayer Agreement may
opt against renewal.

     If operations at the EDNC Baytown Plant are not commenced by February 1,
1999, or upon a change in control of LSB, EDC or EDNC, Bayer has an option to
terminate the Bayer Agreement. EDNC has an option to terminate the Bayer
Agreement upon the failure of Bayer to complete the construction of certain
delivery systems prior to January 1, 1999, and upon the occurrence of certain
events of default which remain uncured. Bayer retains the right of first refusal
with respect to any bona fide third-party offer to purchase any voting stock of
EDNC or any portion of the EDNC Baytown Plant. It is anticipated that
construction of the EDNC Baytown Plant will cost approximately $60 million and
will be completed by late 1998. Construction financing of the EDNC Baytown Plant
is to be provided by an unaffiliated lender. Neither the Company nor EDC has
guaranteed any of the lending obligations for the EDNC Baytown Plant.

Raw Materials

     Anhydrous ammonia represents the primary component in the production of
most of the products of the Chemical Business. See "Management's Discussion and
Analysis of Financial Condition and Results of Operation." The Chemical Business
currently purchases approximately 220,000 tons of anhydrous ammonia per year for
use in its manufacture of its products. The Company has contracts with two
suppliers of anhydrous ammonia. One contract expires in December 1998 and the
other expires in April 2000. The Chemical Business is required to buy 120,000
tons of its annual requirements of anhydrous ammonia under the contract expiring
in 2000 and the balance under the other contract.

                                      -36-
<PAGE>
 
     The Company believes that it could obtain anhydrous ammonia from other
sources in the event of a termination of the above-referenced contracts, but
such may not be obtainable on as favorable terms.  See "Special Note Regarding
Forward-Looking Statements."

Seasonality

     The Company believes that the only seasonal products of the Chemical
Business are fertilizer and related chemical products sold to the agricultural
industry. The selling seasons for those products are primarily during the spring
and fall planting seasons, which typically extend from February through May and
from September through November in the geographical markets in which the
majority of the Company's agricultural products are distributed. As a result,
the Chemical Business increases its inventory of ammonium nitrate prior to the
beginning of each planting season. Sales to the agricultural markets depend upon
weather conditions and other circumstances beyond the control of the Company.

Regulatory Matters

     Each of the Chemical Business' domestic blasting product distribution
centers are licensed by the Bureau of Alcohol, Tobacco and Firearms in order to
manufacture and distribute blasting products. The Australian and New Zealand
distribution centers are subject to comparable licensing requirements imposed by
their respective controlling government authorities. The Chemical Business is
also subject to extensive federal, state and local environmental laws, rules and
regulations. See "--Environmental Matters" and "--Legal Proceedings."

Competition

     The Chemical Business competes with other chemical companies in its
markets, many of whom have greater financial and other resources than the
Company. The Company believes that competition within the markets served by the
Chemical Business is primarily based upon price, service, warranty and product
performance. The Company believes that the Chemical Business is the leader in
the Texas ammonium nitrate market and is the leading producer of concentrated
nitric acid in the United States for third party sales.

CLIMATE CONTROL BUSINESS

General

     The Company's Climate Control Business manufactures and sells a broad range
of standard and custom designed hydronic fan coils and water source heat pumps
as well as other products for use in commercial and residential HVAC systems.
Demand for the Climate Control Business' products is driven by the construction
of commercial, institutional and residential buildings, the renovation of
existing buildings and the replacement of existing systems. The Climate Control
Business' commercial products are used in a wide variety of buildings, such as
hotels, motels, office buildings, schools, universities, apartments,
condominiums, hospitals, nursing homes, extended care facilities, supermarkets
and superstores. Many of the Company's products are targeted to meet
increasingly stringent indoor air quality and energy efficiency standards.

Hydronic Fan Coils

     The Climate Control Business is the leading provider of hydronic fan coils
targeted to the commercial and institutional markets in the U.S. Hydronic fan
coils use heated or chilled water, provided by a centralized chiller and boiler
through a water pipe system, to condition the air and allow individual room
control. Hydronic fan coil systems are quieter and have longer lives and lower
maintenance costs than comparable systems used where individual room control is
required. The Company believes that its product line of hydronic fan coils is
the most extensive offered by any domestic producer. The breadth of this product
line coupled with customization capability provided by a flexible

                                      -37-
<PAGE>
 
manufacturing process are important components of the Company's strategy for
competing in the commercial and institutional renovation and replacement
markets.

Water Source Heat Pumps

     The Company is a leading U.S. provider of water source heat pumps to the
commercial construction and renovation markets. These are highly efficient
heating and cooling units which enable individual room climate control through
the transfer of heat through a water pipe system which is connected to a
centralized cooling tower or heat injector. Water source heat pumps enjoy a
broad range of commercial applications, particularly in medium to large sized
buildings with many small, individually controlled spaces. The Company believes
the market for commercial water source heat pumps will continue to grow due to
the relative efficiency and long life of such systems as compared to other air
conditioning and heating systems, as well as to the emergence of the replacement
market for those systems.  See "Special Note Regarding Forward-Looking
Statements."

Geothermal Products

     The Climate Control Business is a pioneer in the use of geothermal water
source heat pumps in residential and commercial applications. Geothermal
systems, which circulate water or antifreeze through an underground heat
exchanger, are among the most energy efficient systems available. The Company
believes that an aging installed base of residential HVAC systems, coupled with
the longer life, lower cost to operate, and relatively short payback periods of
geothermal systems will continue to increase demand for its geothermal products,
particularly in the residential replacement market.  See "Special Note Regarding
Forward-Looking Statements."

Hydronic Fan Coil and Water Source Heat Pump Market

     The Company has pursued a strategy of specializing in hydronic fan coils
and water source heat pump products. The annual U.S. market for hydronic fan
coils and water source heat pumps is approximately $225 million. Demand in these
markets is generally driven by levels of repair, replacement, and new
construction activity. The U.S. market for fan coils and water source heat pumps
products has grown on average 6% per year over the last 5 years. This growth has
been fueled by the aging of the installed base of units, the introduction of new
energy efficient systems, upgrades to central air conditioning and increased
governmental regulations restricting the use of ozone depleting refrigerants in
HVAC systems.

Production and Backlog

     Most of the Climate Control Business' production of the above-described
products occurs on a specific order basis. The Company manufactures the units in
many sizes and configurations, as required by the purchaser, to fit the space
and capacity requirements of hotels, motels, schools, hospitals, apartment
buildings, office buildings and other commercial or residential structures. As
of September 30, 1997, the backlog of confirmed orders for the Climate Control
Business was approximately $27.2 million. As of the date of this Prospectus, the
Climate Control Business released substantially all of its September 30, 1997,
backlog to production.

Marketing and Distribution

     The Climate Control Business sells its products to mechanical contractors,
original equipment manufacturers and distributors. The Company's sales to
mechanical contractors primarily occur through independent manufacturer's
representatives, who also represent complementary product lines not manufactured
by the Company. Original equipment manufacturers generally consist of other air
conditioning and heating equipment manufacturers who resell under their own
brand name the products purchased from the Climate Control Business in
competition with the Company. Sales to original equipment manufacturers
accounted for approximately 28% of the sales of the Climate Control Business in
1996.

                                      -38-
<PAGE>
 
Competition

     The Climate Control Business competes with approximately eight companies,
some of whom are also customers of the Company. Some of the competitors have
greater financial and other resources than the Company. The Climate Control
Business manufactures a broader line of fan coil and water source heat pump
products than any other manufacturer in the United States, and the Company
believes that it is competitive as to price, service, warranty and product
performance.

PROPERTIES

Chemical Business

     The Chemical Business primarily conducts manufacturing operations (i) on
150 acres of a 1,400 acre tract of land located in El Dorado, Arkansas (the "El
Dorado Facility"), (ii) in a facility of approximately 60,000 square feet
located on 10 acres of land in Hallowell, Kansas ("Kansas Facility") and (iii)
in a mixed acid plant in Wilmington, North Carolina ("Wilmington Plant"). The
Chemical Business owns all of its manufacturing facilities, with the El Dorado
Facility and the Wilmington Plant subject to mortgages. In addition, the
Chemical Business has four manufacturing facilities in Australia and one in New
Zealand that produce bulk and packaged explosives.

     As of September 30, 1997, the El Dorado Facility was utilized at
approximately 87% of capacity, based on continuous operation.

     The Chemical Business operates its Kansas Facility from buildings located
on an approximate ten-acre site in southeastern Kansas, and a research and
testing facility comprising approximately ten acres, including buildings and
equipment thereon, located in southeastern Kansas, which it owns.

     In addition, the Chemical Business distributes its products through 31
agricultural and explosive distribution centers. The Chemical Business currently
operates 21 agricultural distribution centers, with 15 of the centers located in
Texas (12 of which the Company owns and three of which it leases); one center
located in Oklahoma which the Company owns; two centers located in Missouri (one
of which the Company owns and one of which it leases); and three centers located
in Tennessee (all of which the Company owns). The Chemical Business currently
operates six domestic explosives distribution centers located in Hallowell,
Kansas (owned); Bonne Terre, Missouri (owned); Huntington, West Virginia
(leased); Owensboro and Combs, Kentucky (leased); and Pryor, Oklahoma (leased).
The Chemical Business also has four explosives distribution centers in
Australia, all of which are leased, and one explosives distribution center
located in New Zealand, which is leased.

Climate Control Business

     The Climate Control Business conducts its fan coil manufacturing operations
in a facility located in Oklahoma City, Oklahoma, consisting of approximately
265,000 square feet. As of September 30, 1997, the Climate Control Business was
using the productive capacity of the above-referenced facilities to the extent
of approximately 92%, based on three, eight-hour shifts per day and a five-day
week in one department and one and one-half eight-hour shifts per day and a
five-day week in all other departments. The Climate Control Business leases its
fan coil manufacturing facility. The fan coil manufacturing facility is leased
under the terms of an agreement with Prime Financial Corporation ("Prime"), a
subsidiary of LSB but not a subsidiary of the Company ("Prime Lease"). The term
of the Prime Lease expires on September 7, 2002, and rent is payable at an
annual rate of $475,000. The Prime Lease may be extended for a period of ten
years following the expiration of the initial term. See "Certain Relationships
and Related Transactions."

     The Climate Control Business manufactures most of its heat pump products in
a leased 270,000 square foot facility in Oklahoma City, Oklahoma, which it
leases from an unrelated party. The lease term began March 1, 1988, after
renewal in October 1997, and expires February 28, 2003, with options to renew
for additional five-year periods, and

                                      -39-
<PAGE>
 
currently provides for the payment of rent in the amount of $52,389 per month.
The Company also has an option to acquire the facility at any time in return for
the assumption of the then outstanding balance of the lessor's mortgage. As of
September 30, 1997, the productive capacity of this manufacturing operation was
being utilized to the extent of approximately 86%, based on one eight-hour shift
per day and a five-day week.

     All of the properties utilized by the Climate Control Business are
considered by the Company management to be suitable and adequate to meet the
current needs of that Business.

EMPLOYEES

     As of September 30, 1997, the Company employed 1,222 persons. As of that
date, (i) the Chemical Business employed 571 persons, with 134 represented by
unions under agreements expiring July 31, 1998, and February 5, 1999, and (ii)
the Climate Control Business employed 651 persons, none of whom are represented
by a union.

ENVIRONMENTAL MATTERS

     The Company and its operations are subject to numerous Environmental Laws
and to other federal, state and local laws regarding health and safety matters
("Health Laws"). In particular, the manufacture and distribution of chemical
products are activities which entail environmental risks and impose obligations
under the Environmental Laws and the Health Laws, many of which provide for
substantial fines and criminal sanctions for violations, and there can be no
assurance that material costs or liabilities will not be incurred by the Company
in complying with such laws or in paying fines or penalties for violation of
such laws. The Environmental Laws and Health Laws and enforcement policies
thereunder relating to the Chemical Business have in the past resulted, and
could in the future result, in penalties, cleanup costs, or other liabilities
relating to the handling, manufacture, use, emission, discharge or disposal of
pollutants or other substances at or from the Company's facilities or the use or
disposal of certain of its chemical products. Significant expenditures have been
incurred by the Chemical Business at the El Dorado Facility in order to comply
with the Environmental Laws and Health Laws. The Chemical Business may be
required to make additional significant site or operational modifications at the
El Dorado Facility, potentially involving substantial expenditures and
reduction, suspension or cessation of certain operations. See "Special Note
Regarding Forward-Looking Statements;" "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Chemical Business" and "-Legal
Proceedings."

     The Arkansas Department of Pollution Control & Ecology ("ADPC&E") performed
an environmental inspection at the Chemical Business' El Dorado Facility in
1994, which included a review of the plant's compliance with Environmental Laws
relating to wastewater and stormwater discharges, air emissions, and solid and
hazardous waste practices. The reports prepared by the ADPC&E in connection with
the inspection noted, in part, that releases of contaminants to groundwater were
suspected to have occurred at the El Dorado Facility. In 1995, the Chemical
Business and the ADPC&E entered into an administrative consent order which
provided for penalties of $150,000 (including $125,000 to be spent on
environmental improvements at the El Dorado Facility), and required the Chemical
Business to investigate the nature and extent of the existing groundwater
contamination, to take steps to reduce future groundwater contamination, and to
address certain other environmental compliance issues at the El Dorado Facility
(the "Inspection Consent Order"). Pursuant to the Inspection Consent Order, the
Chemical Business installed additional monitoring wells at the El Dorado
Facility in accordance with a workplan approved by the ADPC&E, and submitted the
test results to ADPC&E. The results indicated that a risk assessment should be
conducted on nitrates present in the shallow groundwater. The Chemical Business'
consultant has completed this risk assessment, and has forwarded it to the
ADPC&E for approval. The risk assessment concludes that, although there are
contaminants at the El Dorado Facility and in the groundwater, the levels of
such contaminants at the El Dorado Facility and in the groundwater do not
present an unacceptable risk to human health and the environment. Based on this
conclusion, the Chemical Business' consultant has recommended continued
monitoring at the site for five years. The ADPC&E has not yet responded to the
Chemical Business' proposal. There can be no assurance that the risk assessment
will be approved by the ADPC&E, or that further work will not be required.

                                      -40-
<PAGE>
 
     In addition, in accordance with the Inspection Consent Order, the Chemical
Business currently plans to upgrade the El Dorado Facility's wastewater
treatment plant, and anticipates that significant related capital expenditures
will be incurred to complete this project. Because the Company is still
investigating this matter, the Company cannot predict the amount of such
expenditures. Furthermore, the El Dorado Facility's new wastewater permit
currently is being reviewed for renewal by the ADPC&E. The new permit may impose
additional or more stringent limitations on the plant's wastewater discharges.
The Company believes, although there can be no assurance, that any such new
limitations would not have a material adverse effect on the Company.  See
"Special Note Regarding Forward-Looking Statements."

     During May 1997, approximately 2,000 gallons of nitric acid spilled when a
valve in a storage vessel located at the El Dorado Facility failed, resulting in
a release of such acid to a stormwater drain, and according to ADPC&E records, a
minor fish kill in a creek near the El Dorado Facility. The Chemical Business
and the ADPC&E are currently negotiating a proposed civil consent administrative
order to resolve this matter, which would require the payment of a civil
penalty. Based on negotiations to date, the Company does not believe such
penalty will exceed $25,000. The Company also anticipates that the order will
require the Chemical Business to undertake certain additional compliance
measures and equipment improvements related to the El Dorado Facility's
wastewater treatment system. Although the Company does not believe the order
will have a material adverse effect on the Company's business, there can be no
assurance that penalties and required expenditures related to the order will not
have such an effect.  See "Special Note Regarding Forward-Looking Statements."

     The El Dorado Facility's air permit required it to cease operation of
certain older nitric acid concentrators (the "Older Nitric Acid Concentrators")
within a certain period of time after the initiation of operations of the DSN
Plant. Due to certain start-up problems with the DSN Plant, including excess
emissions from various emission sources, the Chemical Business and the ADPC&E
entered into certain agreements, including an administrative consent order (the
"Air Consent Order") in 1995 to resolve certain of the Chemical Business' past
violations and to permit the Chemical Business to operate the Older Nitric Acid
Concentrators until the ADPC&E has made a final decision regarding the El Dorado
Facility's air permit, including whether the Older Nitric Acid Concentrators may
continue to operate. Although the Company expects that the Chemical Business
will be able to continue to operate the Older Nitric Acid Concentrators, there
can be no assurance that the ADPC&E will allow it to continue to do so. The Air
Consent Order also provides for payment of a civil penalty of $50,000, which the
Chemical Business has paid, and requires installation of certain pollution
control equipment and completion of certain maintenance activities at the El
Dorado Facility to eliminate certain off-site hazing problems. The Air Consent
Order was amended in 1996 and 1997. The second amendment to the Air Consent
Order (the "1997 Amendment") provided for certain stipulated penalties of $1,000
per hour to $10,000 per day for continued off-site emission events and deferred
enforcement for other alleged air permit violations. The 1997 Amendment
acknowledges that the Chemical Business has completed the installation of the
pollution control equipment and maintenance activities required under the Air
Consent Order. Nonetheless, the Chemical Business was assessed an additional
penalty of $150,000, as well as a payment of an additional $50,000 to fund
certain environmental projects, with respect to a number of alleged permit
violations relating to off-site emissions and other air permit conditions. The
Chemical Business has paid both the penalty and the additional sums required by
the 1997 Amendment. Since the 1997 Amendment and as of the date of this
Prospectus, the Chemical Business has been assessed stipulated penalties of
approximately $55,000 by the ADPC&E for violations of certain provisions of the
1997 Amendment. The Chemical Business believes that the El Dorado Facility has
made progress in controlling certain off-site emissions; however, such off-site
emissions have occurred, and continue to occur, from time to time, which could
result in the assessment of additional penalties against the Chemical Business
by the ADPC&E and could have a material adverse effect on the Company. In
addition, the El Dorado Facility was identified as one of 33 significant
violators of the federal Clean Air Act in a recent review of Arkansas air
programs by the EPA Office of Inspector General. The Company is unable to
predict the impact, if any, of such designation.  See "Special Note Regarding
Forward-Looking Statements."

     During 1996, the Chemical Business expended approximately $6.8 million in
connection with capital expenditures relating to compliance with federal, state
and local Environmental Laws at its El Dorado Facility, including, but not
limited to, compliance with the Air Consent Order, as amended. For the period
from January 1, 1997, to September 30, 1997, the Chemical Business has spent
approximately $1.0 million for capital expenditures relating

                                      -41-
<PAGE>
 
to environmental control facilities at its El Dorado Facility to comply with
Environmental Laws, including, but not limited to, the Air Consent Order, as
amended, and it is anticipated that such expenditures will total approximately
$1.0 million for the balance of 1997 and 1998. No assurance can be made that the
actual expenditures of the Chemical Business for such matters will not exceed
the estimated amounts by a substantial margin, which could have a material
adverse effect on the Company and its financial condition. The amount to be
spent during the balance of 1997 and 1998 for capital expenditures related to
compliance with Environmental Laws is dependent upon a variety of factors,
including, but not limited to, the occurrence of additional releases or
threatened releases (particularly air emissions) into the environment, or
changes in the Environmental Laws (or in the enforcement or interpretation by
any federal or state agency or court of competent jurisdiction). See "Special
Note Regarding Forward-Looking Statements."  Failure to satisfactorily resolve
the pending noncompliance issues with the ADPC&E, or additional orders from the
ADPC&E imposing penalties, or requiring the Chemical Business to spend more for
environmental improvements or curtail production activities at the El Dorado
Facility, could have a material adverse effect on the Company.

     The Chemical Business is also involved in various lawsuits pending in
federal court relating to environmental issues at the El Dorado Facility similar
to the environmental issues discussed above and covered by the Air Consent
Order, as amended, with the ADPC&E. The amounts to be spent during the balance
of 1997 and 1998, as discussed herein, for compliance with applicable federal,
state and local Environmental Laws at the El Dorado Facility do not include
expenditures, if any, that may be required to comply with any court order
resulting from such lawsuits. See "Business--Legal Proceedings."

LEGAL PROCEEDINGS

     Roy Carr, et al. v. El Dorado Chemical Company ("Carr Case"); Richard
Detraz, et al. v. El Dorado Chemical Company ("Detraz Case"); Roy A. Carr, Sr.,
et al. v. El Dorado Chemical Company ("Citizen Suit"). The Carr Case, which was
filed against EDC on June 26, 1996, the Detraz Case, which was filed against EDC
on October 14, 1996, and the Citizen Suit, which was filed against EDC on
October 17, 1996, are pending in the United States District Court, Western
District of Arkansas, El Dorado Division. The plaintiffs in the Carr Case and
the Citizen Suit reside in the area surrounding EDC's El Dorado Facility, while
the plaintiffs in the Detraz Case reside in various locations throughout the El
Dorado, Arkansas, metropolitan area. Because the parties to the Carr Case and
the Citizen Suit are substantially the same, and the cases allege similar facts,
the court consolidated these two cases, although they are based on different
legal theories. The plaintiffs in the Citizen Suit allege violations of the
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"),
as amended by the Emergency Planning Community Right-To-Know Act ("EPCRA"), the
Clean Air Act and the Clean Water Act, and permits issued to EDC under certain
of these laws. Under the terms of such laws, the plaintiffs in the Citizen Suit
are seeking penalties of up to $25,000 for each day in which EDC violated such
acts, if any, and injunctive relief requiring EDC to remediate any such alleged
violations and relating to future violations. The plaintiffs in the Carr Case
seek an unspecified amount of damages under various toxic tort theories for
alleged bodily injury and property damage resulting from alleged releases of
toxic substances into the environment from the El Dorado Facility, as well as
punitive damages and damages for any diminution in the value of plaintiffs'
property resulting from the alleged releases. The Detraz Case, like the Carr
Case, is based on various toxic tort theories. The plaintiffs in the Detraz Case
are seeking to have the case certified as a class action for persons who
allegedly have been affected by emissions from the El Dorado Facility, which
certification EDC is contesting.  During January 1998, the Company's Chemical
Business agreed in principal to settle the Detraz Case, which settlement, if
completed, will be funded from the Company's EIL Insurance (as defined below).
The settlement of the Detraz Case is subject to court approval, execution of
definitive settlement agreements, and confirmation from the Company's EIL
Insurance carrier that it will pay the full amount of such settlement.  The
Company intends to vigorously defend itself in connection with the remaining
lawsuits described above.

     In January 1997, EDC entered into an agreed order (the "Carr Order") in the
Carr Case pursuant to which EDC agreed (i) not to emit substances from the El
Dorado Facility which create a nuisance on the plaintiffs' property (as defined
in the Carr Order to include any off-site haze that reaches the plaintiffs'
property), (ii) to operate in compliance with emission limitations and certain
other requirements established by EDC's permit for the El Dorado Facility, (iii)

                                      -42-
<PAGE>
 
to establish a system for monitoring and reporting (including to the plaintiffs)
permit exceedences and releases of reportable quantities of hazardous
substances. The Carr Order further provides that the court shall retain
jurisdiction of the issues covered by the Carr Order for the purposes of
enabling the parties in the Carr Case to apply to the court for any order that
may be necessary to interpret, carry out, modify or enforce the Carr Order. In
connection with the Carr Order, the plaintiffs have filed two motions for
contempt against EDC for violations, or alleged violations, of the Carr Order.
On one occasion, the court held that EDC had created a nuisance at the property
of one of the plaintiffs as a result of certain emissions from the El Dorado
Facility and assessed a $500 penalty against EDC and ordered EDC to pay
plaintiffs' attorneys' fees in connection with bringing such motion. The
plaintiffs in the Carr Case withdrew the other motion for contempt pending an
audit of the operation of the El Dorado Facility.  The parties to the Carr Case
have entered into an audit agreement to evaluate facility operations and
emissions.  An audit report is anticipated during the first half of 1998. Other
incidents have occurred or may occur in the future which could give rise to the
filing of additional motions for contempt alleging violations of the Carr Order,
and, if the Company is found to have violated the Carr Order, it could result in
the possible assessment of additional fines, penalties and costs against EDC
that could have a material adverse effect on the Company and/or the Chemical
Business.  See "Special Note Regarding Forward-Looking Statements."

     The Chemical Business maintains an Environmental Impairment Insurance
Policy ("EIL Insurance") that provides coverage to the Chemical Business for
certain discharges, dispersal, releases, or escapes of certain contaminants and
pollutants into or upon land, the atmosphere or any water course or body of
water from the El Dorado Facility, which has caused bodily injury, property
damage or contamination to others or to other property not located on the El
Dorado Facility site. The EIL Insurance provides limits of liability for each
loss up to $10 million, except $5 million for all remediation expenses, with the
maximum limit of liability for all claims under the EIL Insurance not to exceed
$10 million for all losses and remediation expenses. The EIL Insurance also
provides for a retention of the first $500,000 per loss or remediation expense
to be paid by the Chemical Business. The Chemical Business has given notice of
the pending legal actions in the Carr Case, the Detraz Case and the Citizen Suit
to the EIL Insurance carrier ("EIL Carrier"), and the EIL Carrier has agreed to
provide a defense for the Company in each case. The defense regarding the
Citizen Suit has been undertaken by the EIL Carrier subject to a reservation of
rights, indicating that the EIL Carrier may make a determination that it does
not believe that any liability in the Citizen Suit is covered by the EIL
Insurance, and, on that basis, deny coverage regarding the Citizens Suit and
seek reimbursement of its related legal expenditures paid in connection with the
Citizen Suit. The Company believes that the EIL Insurance will provide coverage
for actual damages, if any, sustained by the plaintiffs in the Carr Case and the
Detraz Case up to the limits of the policy in excess of the $500,000 retention,
but will not provide coverage for punitive damages, and may not provide coverage
for the costs of injunctive relief and penalties resulting from the litigation.
As of the date of this Prospectus, the Company has submitted claims to the EIL
Carrier of approximately $1.2 million for legal and consulting fees and
expenses, or approximately $700,000 in excess of the self-insured retention. The
EIL Carrier has reimbursed the Chemical Business for $405,000 of such fees and
expenses  (after taking into account the amount of the retention under the EIL
Insurance) and has agreed to pay such future fees and expenses, subject to
reservation of rights relating to the Citizen Suit.  The amount of the Detraz
settlement, if completed, and the amount paid under the EIL Insurance for legal
and other expenses relating to the defense of these lawsuits reduce the amount
that may be paid under the EIL Insurance.

     Based on currently available information, the Company does not believe the
outcome of the Carr Case and the Citizen Suit, after settlement of the Detraz
Case, if completed, will have a material adverse effect on the Company's
financial position or results of operation. No assurance, however, can be given
that the actual results of these litigation matters will not have such an
effect, if, for example, the court assesses substantial penalties or fines
against the Chemical Business in the Citizen Suit; the EIL Insurance does not
provide coverage to the Chemical Business for additional claims asserted against
the Company in the pending cases; the damages or penalties awarded or assessed
are not covered by the EIL Insurance (such as fines and punitive damages); or
the damages awarded or assessed in connection with, and expenditures to defend,
such cases and the amount of the Detraz settlement, if completed, exceed the EIL
Insurance coverage limits.  See "Special Note Regarding Forward-Looking
Statements."

     Arch Mineral Corporation, et al. v. ICI Explosives USA, Inc., et al.  On
May 24, 1996, the plaintiffs filed this civil cause of action against EDC and
five other unrelated commercial explosives manufacturers alleging that the
defendants allegedly violated certain federal and state antitrust laws in
connection with alleged price fixing of certain explosive products. This cause
of action is pending in the United States District Court, Southern District of
Indiana. The plaintiffs are suing for an unspecified amount of damages, which,
pursuant to statute, plaintiffs are seeking be trebled, together with costs.
Plaintiffs are also seeking a permanent injunction enjoining defendants from
further alleged anti-competitive activities. Based on the information presently
available to EDC, EDC does not believe that EDC conspired with any party,
including, but not limited to, the five other defendants, to fix prices in
connection with the sale of commercial explosives. Discovery has only recently
commenced in this matter. EDC intends to vigorously defend itself in this
matter.  See "Special Note Regarding Forward-Looking Statements."

     ASARCO v. ICI, et al. The U. S. District Court for the Eastern District of
Missouri has granted ASARCO and other plaintiffs in a lawsuit originally
brought against various commercial explosives manufacturers in Missouri, and
consolidated with other lawsuits in Utah, leave to add EDC as a defendant in
that lawsuit. This lawsuit alleges a national conspiracy, as well as a regional
conspiracy, directed against explosive customers in Missouri and seeks
unspecified damages. EDC has been included in this lawsuit because it sold
products to customers in Missouri during a time in which other defendants have
admitted to participating in an antitrust conspiracy, and because it has been
sued in the Arch case discussed above. Based on the information presently
available to EDC, EDC does not believe that EDC conspired with any party, to fix
prices in connection with the sale of commercial explosives. EDC intends to
vigorously defend itself in this matter.  See "Special Note Regarding Forward-
Looking Statements."

     Department of Justice Investigation of Explosives Industry.  For several
years, certain members of the explosives industry have been the focus of grand
jury investigations being conducted by the DOJ in connection with criminal
antitrust allegations involving price fixing. Certain explosives companies,
other than the Company, including all the Company's major competitors, and
individuals employed by certain of those competitors, were indicted and have
pled guilty to criminal antitrust violations. The guilty pleas have resulted in
a total of nearly $40 million in criminal fines. In connection with the grand
jury investigation, the Company's Chemical Business received and has complied
with two document subpoenas, certain of the Company's Chemical Business
employees have been interviewed by the DOJ under grants of immunity from
prosecution, and certain of the Company's Chemical Business employees have
testified under subpoena before a grand jury under grants of immunity in
connection with the investigation. The Company believes that it has cooperated
fully with the government's investigation. Recently, the Company had been
informed by an official of the DOJ that it was not currently a target of the
above investigation or of any grand jury investigating criminal antitrust
activity in the explosives or ammonium nitrate industries.  See "Special Note
Regarding Forward-Looking Statements."

     Eugene Lowe, et al. v. Teresa Trucking, Inc., pending in the Circuit Court
of Lincoln County, West Virginia. During the third quarter of 1997, EDC was
served with this lawsuit in which approximately 27 plaintiffs have sued
approximately 13 defendants, including EDC, alleging personal injury and
property damage for undifferentiated compensatory and punitive damages of
approximately $7,000,000. Specifically, the plaintiffs assert blast damage
claims, nuisance (road dust from coal trucks) and personal injury claims
(exposure to toxic materials in blasting materials) on behalf of residents
living near the Heartland Coal Company ("Heartland") strip mine in Lincoln
County, West Virginia. Heartland employed EDC to provide blasting materials and
personnel to load and shoot holes drilled by employees of Heartland. Down hole
blasting services were provided by EDC at Heartland's premises from
approximately August 1991, until approximately August 1994. Subsequent to August
1994, EDC supplied blasting materials to the reclamation contractor at
Heartland's mine. In connection with EDC's activities at Heartland, EDC has
entered into a contractual indemnity to Heartland to indemnify Heartland under
certain conditions for acts or actions taken by EDC or for which EDC failed to
take, and Heartland is alleging that EDC is liable thereunder for Heartland's
defense costs and any losses to, or damages sustained by, the plaintiffs in this
lawsuit.

     Discovery has only recently begun in this matter, and the Company intends
to vigorously defend itself in this matter. EDC has provided notification of
this lawsuit to its three insurance carriers providing primary insurance

                                      -44-
<PAGE>
 
coverage to EDC during the period covered by the plaintiff's allegations.  The
one insurance carrier whose policy provides for defense has indicated it will
share in the defense of this lawsuit.  The remaining two insurance carriers have
indicated that they will be defending this lawsuit under a reservation of
rights.

EMPLOYMENT CONTRACTS; TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL
ARRANGEMENTS

Termination of Employment and Change in Control Agreements

     LSB has entered into severance agreements with Jack E. Golsen, Barry H.
Golsen, Tony M. Shelby, David R. Goss, Jim D. Jones, James L. Wewers, David M.
Shear, and certain other officers of LSB and subsidiaries of LSB.

     Each severance agreement provides (among other things) that if, within 24
months after the occurrence of a change in control of LSB, LSB terminates the
officer's employment other than for cause (as defined), or the officer
terminates his employment for good reason (as defined), LSB must pay the officer
an amount equal to 2.9 times the officer's base amount (as defined). The phrase
"base amount" means the average annual gross compensation paid by LSB to the
officer and includable in the officer's gross income during the period
consisting of the most recent five-year period immediately preceding the change
in control. If the officer has been employed by LSB for less than five years,
the base amount is calculated with respect to the most recent number of taxable
years ending before the change in control that the officer worked for LSB.

     The severance agreements provide that a "change in control" means a change
in control of LSB of a nature that would require the filing of a Form 8-K with
the Securities and Exchange Commission and, in any event, would mean when (1)
any individual, firm, corporation, entity, or group (as defined in Section
13(d)(3) of the Exchange Act becomes the beneficial owner, directly or
indirectly, of 30% or more of the combined voting power of the LSB's outstanding
voting securities having the right to vote for the election of directors, except
acquisitions by (a) any person, firm, corporation, entity, or group which, as of
the date of the severance agreement, has that ownership, or (b) Jack E. Golsen;
his wife; his children and the spouses of his children; his estate; executor or
administrator of any estate, guardian or custodian for Jack E. Golsen, his wife,
his children, or the spouses of his children; any corporation, trust,
partnership, or other entity of which Jack E. Golsen, his wife, children, or the
spouses of his children own at least 80% of the outstanding beneficial voting or
equity interests, directly or indirectly, either by any one or more of the 
above-described persons, entities, or estates; and certain affiliates and
associates of any of the above-described persons, entities, or estates; (2)
individuals who, as of the date of the severance agreement, constitute the Board
of Directors of LSB (the "Incumbent Board") and who cease for any reason to
constitute a majority of the Board of Directors except that any person becoming
a director subsequent to the date of the severance agreement, whose election or
nomination for election is approved by a majority of the Incumbent Board (with
certain limited exceptions), will constitute a member of the Incumbent Board; or
(3) the sale by LSB of all or substantially all of its assets.


     Except for the severance agreement with Jack E. Golsen, the termination of
an officer's employment with LSB "for cause" means termination because of (a)
the mental or physical disability from performing the officer's duties for a
period of 120 consecutive days or 180 days (even though not consecutive) within
a 360 day period; (b) the conviction of a felony; (c) the embezzlement by the
officer of LSB of assets resulting in substantial personal enrichment of the
officer at the expense of LSB; or (d) the willful failure (when not mentally or
physically disabled) to follow a direct written order from LSB's Board of
Directors within the reasonable scope of the officer's duties performed during
the 60-day period prior to the change in control. The definition of "Cause"
contained in the severance agreement with Jack E. Golsen means termination
because of (a) the conviction of Mr. Golsen of a felony involving moral
turpitude after

                                      -48-
<PAGE>
 
all appeals have been completed; or (b) if due to Mr. Golsen's serious, willful,
gross misconduct or willful, gross neglect of his duties has resulted in
material damages to LSB and its subsidiaries, taken as a whole, provided that
(i) no action or failure to act by Mr. Golsen will constitute a reason for
termination if he believed, in good faith, that such action or failure to act
was in LSB's or its subsidiaries' best interest, and (ii) failure of Mr. Golsen
to perform his duties hereunder due to disability shall not be considered
willful, gross misconduct or willful, gross negligence of his duties for any
purpose.

     The termination of an officer's employment with LSB for "good reason" means
termination because of (a) the assignment to the officer of duties inconsistent
with the officer's position, authority, duties, or responsibilities during the
60-day period immediately preceding the change in control of LSB or any other
action which results in the diminishment of those duties, position, authority,
or responsibilities; (b) the relocation of the officer; (c) any purported
termination by LSB of the officer's employment with LSB otherwise than as
permitted by the severance agreement; or (d) in the event of a change in control
of LSB, the failure of the successor or parent company to agree, in form and
substance satisfactory to the officer, to assume (as to a successor) or
guarantee (as to a parent) the severance agreement as if no change in control
had occurred.

     Except for the severance agreement with Jack E. Golsen, each severance
agreement is effective until the earlier of (a) three years after the date of
the severance agreement, or (b) the officer's normal retirement date from LSB;
however, beginning on the first anniversary of the severance agreement and on
each annual anniversary thereafter, the term of the severance agreement
automatically extends for an additional one-year period, unless LSB gives notice
otherwise at least 60 days prior to the anniversary date. The severance
agreement with Jack E. Golsen is effective for a period of three years from the
date of the severance agreement; except that, commencing on the date one year
after the date of such severance agreement and on each annual anniversary
thereafter, the term of such severance agreement shall be automatically extended
so as to terminate three years from such renewal date, unless LSB gives notices
otherwise at least one year prior to the renewal date.

     Effective June 1, 1994, LSB extended until June 1, 1999, the option period
of a nonqualified stock option previously granted to Jack E. Golsen for the
purchase of 165,000 shares of LSB's Common Stock at an exercise price of $2.625
per share (the "Extended NQSO"). The Extended NQSO vests and becomes exercisable
at 20% per year on June 1, 1995, 1996, and 1997, and the remaining 40% becomes
exercisable on June 1, 1998. The terms of the Extended NQSO provide, in part,
that the Extended NQSO shall become immediately exercisable upon a change in
control of LSB. A "change in control" for purposes of the Extended NQSO, shall
occur upon any of the following events: (i) consummation of any of the following
transactions: any merger, recapitalization, or other business combination of LSB
pursuant to which LSB is the non-surviving corporation, unless the majority of
the holders of Common Stock immediately prior to such transaction will own at
least 50% of the total voting power of the then outstanding securities of the
surviving corporation immediately after such transaction; (ii) a transaction in
which any person, corporation, or other entity (A) shall purchase any Common
Stock pursuant to a tender offer or exchange offer, without the prior consent of
the Board of Directors or (B) shall become the "beneficial owner" (as such term
is defined in Rule 13(d)(3) under the Exchange Act of securities of LSB
representing 50% or more of the total voting power of the then outstanding
securities of LSB; or (iii) if, during any period of two consecutive years,
individuals who, at the beginning of such period, constituted the entire Board
of Directors and any new director whose election by the Board of Directors, or
nomination for election by LSB's stockholders was approved by a vote of at least
two-thirds of the directors then still in office who either were directors at
the beginning of the period or whose election or nomination for election by the
stockholders was previously approved, cease for any reason to constitute a
majority thereof.

Employment Agreement

     In March 1996, LSB entered into an employment agreement with Jack E.
Golsen. The employment agreement requires LSB to employ Jack E. Golsen as an
executive officer of LSB for an initial term of three years and provides for two
automatic renewals of three years each unless terminated by either party by the
giving of written notice at least one year prior to the end of the initial or
first renewal period, whichever is applicable. Under the terms of such

                                      -49-
<PAGE>
 
employment agreement, Mr. Golsen shall (i) be paid an annual base salary at his
1995 base rate, as adjusted from time to time by the Compensation Committee, but
such shall never be adjusted to an amount less than Mr. Golsen's 1995 base
salary, (ii) be paid an annual bonus in an amount as determined by the
Compensation Committee, and (iii) receive from LSB certain other fringe
benefits. The employment agreement provides that Mr. Golsen's employment may not
be terminated, except (i) upon conviction of a felony involving moral turpitude
after all appeals have been exhausted, (ii) Mr. Golsen's serious, willful, gross
misconduct or willful, gross negligence of duties resulting in material damage
to LSB and its subsidiaries, taken as a whole, unless Mr. Golsen believed, in
good faith, that such action or failure to act was in LSB's or its subsidiaries'
best interest, and (iii) Mr. Golsen's death; provided, however, no such
termination under (i) or (ii) above may occur unless and until LSB has delivered
to Mr. Golsen a resolution duly adopted by an affirmative vote of three-fourths
of the entire membership of the Board of Directors at a meeting called for such
purpose after reasonable notice given to Mr. Golsen finding, in good faith, that
Mr. Golsen violated (i) or (ii) above. If Mr. Golsen's employment is terminated
in breach of the employment agreement, then he shall, in addition to his other
rights and remedies, receive and LSB shall pay to Mr. Golsen (i) in a lump sum
cash payment, on the date of termination, a sum equal to the amount of Mr.
Golsen's annual base salary at the time of such termination and the amount of

of years remaining under the employment agreement or (b) four, if such

agreement for the remainder of the term of the employment agreement, or, if
terminated at any time during the last 12 months of the initial period or first
renewal period, then during the remainder of the term and the next renewal
period.

     If there is a "change in control" (as defined in the severance agreement
between Mr. Golsen and LSB) and within 24 months after such change in control
Mr. Golsen is terminated, other than for Cause (as defined in the severance
agreement), then in such event, the severance agreement between Mr. Golsen and

     If Mr. Golsen becomes disabled and is not able to perform his duties under
the employment agreement as a result thereof for a period of 12 consecutive
months within any two year period, the Company shall pay Mr. Golsen his full
salary for the remainder of the term of the employment agreement and thereafter
60% of such salary until Mr. Golsen's death.

Preferred Rights Plan

     On February 17, 1989, LSB's Board of Directors declared a dividend to its
stockholders of record on February 27, 1989, of one preferred stock purchase
right on each of LSB's outstanding shares of common stock. The rights expire on
February 27, 1999. LSB issued the rights, among other reasons, in order to
assure that all of LSB's stockholders receive fair and equal treatment in the
event of any proposed takeover of LSB and to guard against partial tender
abusive tactics to gain control of LSB. The rights will become exercisable only
if a person or group acquires beneficial ownership of 30% or more of LSB's
common stock or announces a tender or exchange offer, the consummation of which
would result in the ownership by a person or group of 30% or more of the LSB
common stock, except any acquisition by Jack E. Golsen, Chairman of the Board
and President of LSB, and certain other related persons or entities.

     Each right (other than the rights, owned by the acquiring person or members
of a group that causes the rights to become exercisable, which become void) will
entitle the stockholder to buy one one-hundredth of a share of a new series of
participating preferred stock at an exercise price of $14.00 per share. Each one
one-hundredth of a share of the new preferred stock purchasable upon the
exercise of a right has economic terms designed to approximate the value of one
share of LSB's common stock. If another person or group acquires LSB in a merger
or other business combination transaction, each right will entitle its holder
(other than rights owned by that person or group, which become void) to purchase
at the right's then current exercise price, a number of the acquiring company's
common shares which at the time of such transaction would have a market value
two times the exercise price of the right. In addition, if a person or

                                      -50-
<PAGE>
 
group (with certain exceptions) acquires 30% or more of LSB's outstanding common
stock, each right will entitle its holder (other than the rights owned by the
acquiring person or members of the group that results in the rights becoming
exercisable, which become void), to purchase at the right's then current
exercise price, a number of shares of LSB's common stock having a market value
of twice the right's exercise price in lieu of the new preferred stock.

     Following the acquisition by a person or group of beneficial ownership of
30% or more of LSB's outstanding common stock (with certain exceptions) and
prior to an acquisition of 50% or more of LSB's common stock by the person or
group, the Board of Directors may exchange the rights (other than rights owned
by the acquiring person or members of the group that results in the rights
becoming exercisable, which become void), in whole or in part, for shares of
LSB's common stock. That exchange would occur at an exchange ratio of one share
of common stock, or one one-hundredth of a share of the new series of
participating new preferred stock, per right.

     Prior to the acquisition by a person or group of beneficial ownership of
30% or more of LSB's common stock (with certain exceptions), LSB may redeem the
rights for one cent per right at the option of LSB's Board of Directors. LSB's
Board of Directors also has the authority to reduce the 30% thresholds to not
less than 10%.

         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS

     All of the Company's issued and outstanding capital stock is owned by LSB.
As a result, the following table sets forth certain information with respect to
the beneficial ownership of the voting common stock and voting preferred stock
of LSB as of November 30, 1997, with respect to each person (including any
"group" as used in Section 13(d)(3) of the Securities Act) that the Company
knows to have beneficial ownership of more than 5% of the LSB's voting common
stock and voting preferred stock. A person is deemed to be the beneficial owner
of shares which could be acquired by such person within 60 days of November 30,
1997, such as upon the exercise of options. Because of the requirements of the
Securities and Exchange Commission as to the method of determining the amount of
shares an individual or entity may beneficially own, the amounts shown as to
beneficial ownership of shares of LSB for an individual or entity may include
shares also considered beneficially owned by others.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

FORMATION AND CAPITALIZATION OF COMPANY

     The Company was formed as an Oklahoma corporation and a wholly owned
subsidiary of LSB on October 17, 1997. In November 1997, the Company acquired
its subsidiaries through capital contributions of each subsidiary's outstanding
stock from LSB to the Company, except Northwest Financial Corporation
("Northwest"), which was contributed to the Company by Prime, a wholly owned
subsidiary of LSB but not a subsidiary of the Company. As of the date of this
Prospectus, LSB owns 95% and Prime owns the remaining 5% of the issued and
outstanding capital stock of the Company.

IEC LEASE

     Prime, a subsidiary of LSB but not a subsidiary of the Company, owns the
facilities utilized by the fan coil operations of the Climate Control Business.
The Climate Control Business has leased such facilities from Prime pursuant to a
lease agreement which provides for a term ending on March 6, 2000. The lease is
renewable by the Climate Control Business for an additional ten-year term on the
same terms, including rental amount. The rental amount is $475,000 per year,
payable in monthly installments.

EDC PURCHASE

     In 1983, LSB Chemical Corp. ("LSBC"), a subsidiary of the Company, acquired
all of the outstanding stock of EDC from its then four stockholders ("Ex-
Stockholders"). A substantial portion of the purchase price consisted of an
earnout based primarily on the annual after-tax earnings of EDC for a 10-year
period. During 1989, two of the Ex-Stockholders received LSBC promissory notes
for a portion of their earnout, in lieu of cash, totaling approximately
$896,000, payable $496,000 in January 1990, and $400,000 in May 1994. LSBC
agreed to a buyout of the balance of the earnout from the four Ex-Stockholders
for an aggregate purchase amount of $1,231,000. LSBC purchased for cash the
earnout from two of the Ex-Stockholders and issued multi-year promissory notes
totaling $676,000 to the other two Ex-Stockholders. Jack E. Golsen guaranteed
LSBC's payment obligation under the promissory notes. These promissory notes
have been assigned in their entirety from LSBC to the Company, and the guarantee
by Jack E. Golsen remains in place. The unpaid balance of these notes at
November 30, 1997, was $400,000.

MULTI-CLIMA

     During 1994, a subsidiary of LSB (which is not the Company or a subsidiary
of the Company) obtained an option to acquire all of the stock of Multi-Clima,
S.A., a French manufacturer of air conditioning and heating equipment ("Multi-
Clima"). LSB's subsidiary was granted the option as a result of the subsidiary
loaning to the parent company of Multi-Clima approximately $2.1 million.
Subsequent to the loan of $2.1 million, LSB's subsidiary has loaned to the
parent of Multi-Clima an additional $1.7 million. The amount loaned is secured
by the stock and assets of Multi-Clima. LSB's subsidiary may exercise its option
to acquire Multi-Clima by converting $150,000 of the amount loaned into equity.
The option is currently exercisable and will expire June 15, 1999. As of the
date of this Prospectus, LSB has not decided whether it will exercise the
option.

     For 1996 and 1995, Multi-Clima had revenues of $16.0 million and $15.9
million, respectively, and reported an approximate break-even level of
operations in 1996 and a net loss of $900,000 in 1995.

     Multi-Clima manufactures chillers, which are used in central air
conditioning systems, heat pump and computer room air conditioning and heat pump
units. It is believed that the air conditioning equipment manufactured by Multi-
Clima is generally compatible with the equipment manufactured by the Climate
Control Business. In addition, Multi-Clima may distribute equipment manufactured
by the Climate Control Business and the Climate Control Business may distribute
equipment manufactured by Multi-Clima.

CONTRACTUAL ARRANGEMENTS

Services Agreement

     Under the services agreement (the "Services Agreement"), dated November 21,
1997, between LSB and the Company, LSB provides to the Company and its
subsidiaries various services, including financial and accounting, order entry,
billing, credit, payable, insurance, legal, human resources, advertising and
marketing, and related administrative and management services, that LSB has
historically provided to the operations and businesses of the Company and its
subsidiaries (other than services provided by the President or Chief Financial
Officer of LSB, whose services will be compensated under the Management
Agreement (as defined)). The Company will pay to or reimburse LSB for all direct
and indirect costs and expenses incurred by LSB in the performance of the
Services Agreement. The term of the Services Agreement is ten years, except LSB
may terminate the Services Agreement on 30 days' written notice to the Company
if (i) the Company defaults under any of the terms or provisions of the Services
Agreement, and such default is not cured during the 30-day notice period, or
(ii) LSB sells 50% or more of the issued and outstanding stock of the Company,
or sells, transfers or disposes of all, or substantially all, of the assets of
the Company. The historical financial statements for the Company reflect
reimbursement to LSB for services of $1.8 million during each of 1994, 1995, and
1996 and $1.4 million during the nine month period from January 1, 1997, to
September 30, 1997.

     The Services Agreement provides that the Company will pay to, or reimburse,
LSB for the value of the office facilities of LSB, including LSB's principal
offices and financial accounting offices utilized in the performance of the
Services Agreement. LSB will determine the proportionate usage of such
facilities by LSB and the Company, and the Company will pay to, or reimburse,
LSB for its proportionate share of such usage.

     The Services Agreement also provides that LSB will permit employees of the
Company and its subsidiaries to participate in the benefit plans and programs
sponsored by LSB until the termination of the Services Agreement. So long as
employees of the Company and its subsidiaries continue to participate in LSB's
benefit plans and programs, the contributions of such employees to such plans
and programs and the costs of participation by such persons in such plans and
programs will be accounted for separately from contributions of, and costs of
participation by, employees of LSB and its other subsidiaries. The Company will
pay to, or reimburse, LSB for the costs associated with participation by the
employees of the Company and LSB's benefit plans and programs. Upon the
termination of the Services Agreement, each of LSB and the Company will be
responsible for all aspects of its respective benefit plans and programs.

Management Agreement

     Under the management agreement (the "Management Agreement"), dated November
21, 1997, between LSB and the Company, which provides that LSB will provide to
the Company, on a nonexclusive basis, managerial oversight and guidance
concerning the broad policies, strategic decisions and operations of the Company
and the Subsidiaries, and the rendering of such further managerial assistance as
deemed reasonably necessary by LSB.

     The term of the Management Agreement is ten years. The Management Agreement
may be terminated sooner by LSB upon 30 days' prior written notice to the
Company if (i) the Company defaults under the Management Agreement, and such
default is not cured to the reasonable satisfaction of LSB prior to the
expiration of such 30-day period or (ii) LSB sells 50% or more of the issued and
outstanding stock of the Company or sells, transfers or disposes of all, or
substantially all, of the assets of the Company. LSB has and will continue to
engage in activities, some of which activities may be in competition with the
Company's activities, other than those it will perform under the Management
Agreement. The Management Agreement will not limit or restrict the terms and
provisions of the Services Agreement.

     The Management Agreement provides that the Company will pay LSB a
Management Fee each calendar year during the term of the Management Agreement of
an amount not to exceed $1,800,000, subject to adjustment under certain
conditions and subject to certain limitations. The Company shall pay LSB such
annual Management Fee on a

                                      -57-
<PAGE>
 
quarterly basis based on the following: (i) if at the end of the first quarter
of the year (March 31), the Company has an EBITDA, on a consolidated basis, for
the three month period from January 1 to March 31 of $6,500,000 or more, a
Management Fee equal to the difference between the amount of such EBITDA, on a
consolidated basis, and $6,500,000, but not to exceed $450,000, (ii) if at the
end of the second quarter of the year (June 30) the Company has an EBITDA, on a
consolidated basis, for the six month period from January 1 to June 30 of such
year of $13,000,000, a Management Fee equal to the amount of such EBITDA, on a
consolidated basis, for the six month period less $13,000,000, but not to exceed
$900,000 less the amount of the Management Fee paid to LSB by the Company for
the first quarter of such year, (iii) if at the end of the third quarter of the
year (September 30) the Company has an EBITDA, on a consolidated basis, for the
nine month period from January 1 to September 30, of such year of $19,500,000, a
Management Fee equal to the amount of such EBITDA, on a consolidated basis, for
the nine month period less $19,500,000, but not to exceed $1,350,000 less the
amount of the Management Fee paid to LSB by the Company for the first and second
quarter of such year, and (iv) if at the end of such year the Company has an
EBITDA, on a consolidated basis, for the twelve months (January 1 to December
31) of $26,000,000, a Management Fee equal to the amount of such EBITDA, on a
consolidated basis, for such twelve month period less $26,000,000, but not to
exceed $1,800,000 less the amount of the Management Fee paid to LSB by the
Company for the first three quarters of such year. If the Company's EBITDA, on a
consolidated basis, is less than $26,000,000 for such year, then LSB shall
return to the Company any Management Fees paid to LSB for the first three
quarters of such year. If the Company's EBITDA for such year, on a consolidated
basis, equals or exceeds $26,000,000 but is less than $26,000,000 plus the
amount of Management Fees paid to LSB for the first three quarters of such year,
LSB shall refund to the Company the difference between $26,000,000 plus the
amount of Management Fees paid to LSB for the first three quarters of the year
and the amount of the Company's EBITDA, on a consolidated basis, for all of such
year. As of January 1 of each year, the quarterly and annual amount of
Management Fee to be paid by the Company to LSB shall be increased
proportionately based on the increase, if any, in the Consumer Price Index
during the preceding calendar year.

Tax Sharing Agreement

     The tax sharing agreement (the "Tax Sharing Agreement"), dated November 21,
1997, between LSB and the Company provides for (i) the allocation of payments of
taxes for periods during which the Company and its subsidiaries and LSB are
included in the same consolidated group for federal income tax purposes or the
same consolidated, combined or unitary returns for state, local or foreign tax
purposes, (ii) the allocation of responsibility for the filing of tax returns,
(iii) the conduct of tax audits and the handling of tax controversies, and (iv)
various related matters. For tax periods beginning after December 1996 and
ending ten years thereafter, so long as the Company is included in LSB's
consolidated federal income tax returns or state consolidated, combined or
unitary tax returns, the Company will be required to pay to LSB an amount equal
to the Company's consolidated federal and state income tax liability calculated
as if the Company and its Subsidiaries were a separate consolidated tax group
and not part of LSB's consolidated tax group. Such amount is payable in
estimated quarterly installments. If the sum of the estimated quarterly
installments is (a) greater than the tax liability of the Company, as determined
by LSB, under the Tax Sharing Agreement, then LSB will refund the amount of the
excess to the Company, or (b) less than the Company's tax liability, as
determined by LSB, under the Tax Sharing Agreement, then the Company will pay to
LSB the amount of the deficiency.

     In addition, subsidiaries of the Company have paid to LSB $1.6 million in
1994, $0.8 million in 1995, and $3.5 million in 1996, a portion of the net
income that subsidiaries of the Company earned on a consolidated basis and an
amount equal to the amount of federal and state income tax liability that those
subsidiaries would have been liable for on a stand-alone basis calculated as
though they were not part of LSB's consolidated group.

INDUSTRIAL SUPPLIES, MACHINES AND CLIMATE CONTROL EQUIPMENT

     From January 1, 1996, to November 30, 1997, certain subsidiaries of LSB
that are not subsidiaries of the Company sold to subsidiaries of the Company
approximately $2.6 million in industrial supplies, machine tools and certain
thermostats.  It is anticipated that such transactions will continue in the
future.

                                      -58-
<PAGE>
 
AFFILIATED LOANS

     The Company and its subsidiaries, at various times, maintained certain
unsecured borrowings from LSB and made loans to LSB and its subsidiaries (other
than the Company and its subsidiaries).  At September 30, 1997, the Company had
loans to LSB of approximately $22.9 million and borrowings  from LSB of
approximately $19.3 million. During November 1997, the Company and LSB offset
substantially all of the amounts due to each other.  As of November 30, 1997,
LSB owed to the Company approximately $3.6 million, bearing interest at an
annual rate of interest of 7%, exclusive of the loan described in the paragraph
below.

     From the net proceeds received by the Company in connection with the
Initial Offering, the Company loaned $10 million to LSB. See "Description of
Notes--Certain Covenants--LSB Note."

REVOLVING CREDIT FACILITY

     LSB, certain subsidiaries of LSB that are not subsidiaries of the Company,
and certain subsidiaries of the Company are parties to the Revolving Credit
Facility. See "Description of Other Indebtedness--Revolving Credit Facility" for
a discussion of the Revolving Credit Facility. LSB and certain subsidiaries of
LSB that are not subsidiaries of the Company have guaranteed all of the
obligations of the Company's subsidiaries under the Revolving Credit Facility.

GUARANTY OF LOANS

     LSB has unconditionally guaranteed the payment of the DSN Loans, which have
an unpaid balance, as of November 30, 1997, of approximately $13.7 million. LSB
has also guaranteed the lease payments due by IEC under a lease purchase
agreement, which provides for the payment of $960,000 over a term of five years
beginning November 1996 at an annual interest rate of 7.5%. In addition, LSB has
unconditionally guaranteed repayment by (i) CM of the CM Loan, the principal
amount of which is approximately $1.3 million as of November 30, 1997, and (ii)
the TES Revolving Facility. See "Description of Other Indebtedness."

EMPLOYEE BENEFIT PLANS

     Prior to the formation of the Company, the employees of the Chemical
Business and the Climate Control Business were eligible to participate in LSB's
Employee Savings Plan, health insurance plan, and various stock option plans.
Under the Services Agreement, employees of the Company continue to be eligible
for all of such plans on the same terms and conditions as LSB's employees.


                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     The Old Notes were originally sold by the Company on the Issue Date to the
Initial Purchaser pursuant to the Purchase Agreement.  The Initial Purchaser
subsequently resold the Old Notes to qualified institutional buyers in reliance
on Rule 144A under the Securities Act.  As a condition to the Purchase
Agreement, the Company and the Initial Purchaser entered into the Registration
Rights Agreement pursuant to which the Company  agreed to (i) file with the
Commission promptly (but in any event on or prior to 60 days) after the Issue
Date, the Exchange Offer Registration Statement relating to the Exchange Offer
for the New Notes, and (ii) use its best efforts to cause the Exchange Offer
Registration Statement to become effective within 150 days after the Issue Date.
Upon the effectiveness of the Exchange Offer Registration Statement, the Company
will offer the New Notes in exchange for the surrender of the Old Notes. The
Registration Rights Agreement provides further that if applicable
interpretations of the staff of the Commission do not permit the consummation of
the Exchange Offer prior to the 150th day following the Issue Date, subject to
certain

                                      -59-
<PAGE>
 
conditions, in the case of any holder of Old Notes not permitted to participate
in the Exchange Offer or of any holder of Old Notes that participates in the
Exchange Offer that receives New Notes that may not be sold without registration
under state and federal securities laws (other than due solely to the status of
such holder as an affiliate of the Company within the meaning of the Securities
Act), or if for any reason the Exchange Offer is not consummated within 180 days
after the Issue Date, or, subject to certain conditions, upon the request of the
Initial Purchaser or the holders of a majority in aggregate principal amount of
the Notes, the Company will, at its cost, file a Shelf Registration Statement to
cover resales of Old Notes by the holders thereof. The Company will use its best
efforts to cause the applicable registration statement to be declared effective
by the Commission as promptly as practicable after the date of filing.

     Based on an interpretation of the staff of the Commission set forth in
several no-action letters to third parties, the Company believes that the New
Notes issued pursuant to the Exchange Offer may be offered for resale, resold
and otherwise transferred by holders thereof without compliance with the
registration and prospectus delivery provisions of the Securities Act. However,
any purchaser of Notes who is an "affiliate" of the Company or who intends to
participate in the Exchange Offer for the purpose of distributing the New Notes
(i) will not be able to rely on the interpretation of the staff of the
Commission set forth in the above referenced no-action letters, (ii) will not be
able to tender its Notes in the Exchange Offer and (iii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any sale or transfer of the Notes unless such sale or transfer
is made pursuant to an exemption from such requirements.

     As contemplated by these no-action letters and the Registration Rights
Agreement, each holder accepting the Exchange Offer is required to represent to
the Company in the Letter of Transmittal that (i) the New Notes are to be
acquired by the Holder or the person receiving such New Notes, whether or not
such person is the holder, in the ordinary course of business, (ii) the holder
or any such other person (other than a broker-dealer referred to in the next
sentence) is not engaging and does not intend to engage in distribution of the
New Notes, (iii) the holder or any such other person has no arrangement or
understanding with any person to participate in the distribution of the New
Notes within the meaning of the Securities Act or resale of the Exchange
Securities in violation of the Securities Act, (iv) neither the holder nor any
such other person is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act, and (v) the holder or any such other person
acknowledges that if such holder or any other person participates in the
Exchange Offer for the purpose of distributing the New Notes it must comply with
the registration and prospectus delivery requirements of the Securities Act in
connection with any resale of the New Notes and cannot rely on those no-action
letters.  As indicated above, each Participating Broker-Dealer that receives a
New Note for its own account in exchange for Old Notes must acknowledge that it
(i) acquired the Old Notes for its own account as a result of market-making
activities or other trading activities, (ii) has not entered into any
arrangement or understanding with the Company or any "affiliate" of the Company
(within the meaning of Rule 405 under the Securities Act) to distribute the New
Notes to be received in the Exchange Offer and (iii) will deliver a prospectus
meeting the requirements of the Securities Act in connection with any resale of
such New Notes.  For a description of the procedures for resales by
Participating Broker-Dealers, see "Plan of Distribution."

     The Registration Rights Agreement provides that unless the Exchange Offer
would not be permitted by a policy of the Commission, the Company will have
commenced the Exchange Offer and will use its best efforts to issue on or prior
to 30 business days after the date on which the Exchange Offer Registration
Statement was declared effective by the Commission New Notes in exchange for all
Old Notes tendered prior thereto in the Exchange Offer. If (i) neither of the
registration statements described above is filed on or before the 60th day
following the Issue Date, (ii) neither of such registration statements is
declared effective by the Commission on or prior to the 150th day after the
Issue Date, (iii) an Exchange Offer Registration Statement becomes effective,
and the Company fails to consummate the Exchange Offer within 30 business days
of the effective date of such registration statement, or (iv) the Shelf
Registration Statement is filed and declared effective but thereafter ceases to
be effective without being succeeded within 30 days by another effective
registration statement (each such event, a "Registration Default"), the Company
will pay liquidated damages ("Liquidated Damages"), to each holder of Old Notes
and New Notes that are received in the Exchange Offer that may not be sold
without restriction under federal or state securities law (together, the
"Registrable Securities") during the first 90-day period immediately following
the occurrence of a Registration Default in an amount equal to one-half of

                                      -60-
<PAGE>
 
one percent (0.5%) per annum of the principal amount of the Registrable
Securities held by such Holder during the first 90-day period immediately
following the occurrence of such Registration Default.  The amount of Liquidated
Damages payable to each Holder will increase by an additional one-half of one
percent (0.5%) per annum of the principal amount of such Registrable Securities
during each subsequent 90-day period, up to a maximum amount of Liquidated
Damages equal to two percent (2.0%) per annum of the principal amount of such
Registrable Securities, which provision for Liquidated Damages will continue
until all Registration Defaults have been cured. All accrued Liquidated Damages
will be paid on or before the semiannual interest payment date for the
Registrable Securities.  Following the cure of all Registration Defaults, the
accrual of Liquidated Damages will cease.

     Holders of Old Notes will be required to make certain representations to
the Company (as described in the Registration Rights Agreement) in order to
participate in the Exchange Offer and will be required to deliver information to
be used in connection with the Shelf Registration Statement in order to have
their Old Notes included in the Shelf Registration Statement. A Holder of Notes
that sells such Notes pursuant to the Shelf Registration Statement generally
would be required to be named as a selling security holder in the related
prospectus and to deliver a prospectus to purchasers, will be subject to certain
of the civil liability provisions under the Securities Act in connection with
such sales and will be bound by the provisions of the Registration Rights
Agreement which are applicable to such a Holder (including certain
indemnification obligations). The Company will provide a copy of the
Registration Rights Agreement to prospective investors upon request.

     The summary herein of certain provisions of the Registration Rights
Agreement does not purport to be complete and is subject to, and is qualified in
its entirety by, all the provisions of the Registration Rights Agreement, a copy
of which is filed as an exhibit to the Exchange Offer Registration Statement of
which this Prospectus is a part.

     Following the consummation of the Exchange Offer, holders of the Old Notes
who were eligible to participate in the Exchange Offer but who did not tender
Old Notes will not have any further registration rights and such Old Notes will
continue to be subject to certain restrictions on transfer.  Accordingly, the
liquidity of the market for such Old Notes could be adversely affected.

TERMS OF THE EXCHANGE OFFER

     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Old Notes
validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on
the Expiration Date.  The Company will issue $1,000 principal amount of New
Notes in exchange for each $1,000 principal amount of outstanding Old Notes
accepted in the Exchange Offer.  Holders may tender some or all of their Old
Notes pursuant to the Exchange Offer.  However, Old Notes may be tendered only
in integral multiples of $1,000.

     The form and terms of the New Notes are the same as the form and terms of
the Old Notes except that (i) the New Notes bear a Series B designation and a
different CUSIP Number from the Old Notes, (ii) the New Notes have been
registered under the Securities Act and hence will not bear legends restricting
the transfer thereof and (iii) the holders of the New Notes will not be entitled
to certain rights under the Registration Rights Agreement, including the
provisions providing for liquidated damages in certain circumstances relating to
the timing of the Exchange Offer, all of which rights will terminate when the
Exchange Offer is terminated.  The New Notes will evidence the same debt as the
Old Notes and will be entitled to the benefits of the Indenture.

     As of the date of this Prospectus, $105,000,000 aggregate principal amount
of Old Notes were outstanding. The Company has fixed the close of business on
________________, 1998, as the record date for the Exchange Offer for purposes
of determining the person to whom this Prospectus and the Letter of Transmittal
will be mailed initially.

     Holders of Old Notes do not have any appraisal or dissenters' rights under
the Oklahoma General Corporation Act or the Indenture in connection with the
Exchange Offer.  The Company intends to conduct the Exchange Offer in

                                      -61-
<PAGE>
 
accordance with the applicable requirements of the Exchange Act and the rules
and regulations of the Commission thereunder.

     The Company will be deemed to have accepted validly tendered Old Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent.  The Exchange Agent will act as agent for the tendering holders
for the purpose of receiving the New Notes from the Company.

     If any tendered Old Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, the certificates for any such unaccepted Old Notes will be returned,
without expense, to the tendering holder thereof as promptly as practicable
after the Expiration Date.

     Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer.  The Company will pay all charges and expenses,
other than transfer taxes in certain circumstances, in connection with the
exchange fees and expenses.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

     The term "Expiration Date" means 5:00 p.m., New York City time, on
___________, 1998, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" will mean the latest
date and time to which the Exchange Offer is extended.

     In order to extend the Exchange Offer, the Company will notify the Exchange
Agent of any extension or oral or written notice and will mail to the registered
holders an announcement thereof, each prior to 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date.

     The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "Conditions" shall
not have been satisfied, by giving oral or written notice of such delay,
extension or termination to the Exchange Agent or (ii) to amend the terms of the
Exchange Offer in any manner.  Any such delay in acceptance, extension,
termination or amendment will be followed as promptly as practicable by oral or
written notice thereof to the registered holders.

INTEREST ON THE NEW NOTES

     The New Notes will bear interest from their date of issuance.  Holders of
Old Notes that are accepted for exchange will receive, in cash, accrued interest
thereon to, but not including, the date of issuance of the New Notes.  Such
interest will be paid with the first interest payment on the Notes on June 1,
1998.  Interest on the Old Notes accepted for exchange will cease to accrue upon
issuance of New Notes.

     Interest on the New Notes is payable semiannually on each June 1 and
December 1, commencing on June 1, 1998.

PROCEDURES FOR TENDERING

     Only a holder of Old Notes may tender such Old Notes in the Exchange Offer.
To tender in the Exchange Offer, a holder must (i) complete, sign and date the
Letter of Transmittal, or a facsimile thereof, and have the signatures thereon
guaranteed if required by the Letter of Transmittal or such facsimile, or (ii)
transmit an Agent's Message in connection with a book-entry transfer, and mail
or otherwise deliver such Letter of Transmittal or such facsimile, or Agent's
Message, together with the Old Notes and any other required documents, to the
Exchange Agent prior to 5:00 p.m. New York City time, on the Expiration Date.
To be tendered effectively, the Old Notes, Letter of Transmittal or an Agent's
Message and other required documents must be completed and received by the
Exchange Agent at the

                                      -62-
<PAGE>
 
address set forth below under "Exchange Agent" prior to 5:00 p.m., New York City
time, on the Expiration Date. Delivery of the Old Notes may be made by book-
entry transfer in accordance with the procedures described below. Confirmation
of such book-entry transfer must be received by the Exchange Agent prior to the
Expiration Date.

     The term "Agent's Message" means a message, transmitted by a book-entry
transfer facility to, and received by, the Exchange Agent forming a part of a
confirmation of book-entry, which states that such book-entry transfer facility
has received an express acknowledgment from the participant in such book-entry
transfer facility tendering the Old Notes that such participant has received and
agrees (1) to participate in the Automated Tender Option Program ("ATOP"); (ii)
to be bound by the terms of the Letter of Transmittal; and (iii) that the
Company may enforce such agreement against such participant.

     By executing the Letter of Transmittal or Agent's Message each holder will
make to the Company the representations set forth above in the third paragraph
under the heading "-Purpose and Effect of the Exchange Offer."

     The tender of Old Notes by a holder and the acceptance thereof by the
Company will constitute agreement between such holder and the Company in
accordance with the terms and subject to the conditions set forth herein and in
the Letter of Transmittal or Agent's Message.

THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL OR AGENT'S
MESSAGE AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
ELECTION AND SOLE RISK OF THE HOLDER.  AS AN ALTERNATIVE TO DELIVERY BY MAIL,
HOLDERS ARE ENCOURAGED TO CONSIDER OVERNIGHT OR HAND DELIVERY SERVICE.  IN ALL
CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE
AGENT BEFORE THE EXPIRATION DATE.  NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD
BE SENT TO THE COMPANY.  HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANK, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.

     Any beneficial owner whose Old Notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf.  See
"Instructions of Registered Holder and/or Book-Entry Transfer Facility
Participant from Beneficial Owner" included with the Letter of Transmittal.

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined) unless
the Old Notes tendered pursuant thereto are tendered (i) by a registered holder
who has not completed the box entitled "Special Registration Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution (as defined).  In the event that signatures
on a Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantee must be by a member firm of the
Medallion System (an "Eligible Institution").

     If the Letter of Transmittal is signed by a person other than the
registered holder of any Old Notes listed therein, such Old Notes must be
endorsed or accompanied by a properly completed bond power, signed by such
registered holder as such registered holder's name appears on such Old Notes
with the signature thereon guaranteed by an Eligible Institution.

     If the Letter of Transmittal or any Old Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, offices of
corporations or other acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and evidence satisfactory to the
Company of their authority to so act must be submitted with the Letter of
Transmittal.

                                      -63-
<PAGE>
 
     The Company understands that the Exchange Agent will make a request
promptly after the date of this Prospectus to establish accounts with respect to
the Old Notes at the Book-Entry Transfer Facility (as defined in the Letter of
Transmittal) for the purpose of facilitating the Exchange Offer, and subject to
the establishment thereof, any financial institution that is a participant in
the Book-Entry Transfer Facility's system may make book entry delivery of Old
Notes by causing such Book Entry Transfer Facility  to transfer such Old Notes
into the Exchange Agent's account with respect to the Old Notes in accordance
with Book-Entry Transfer Facility's procedures for such transfer.  Although
delivery of the Old Notes may be effected through book-entry transfer into the
Exchange Agent's account at the Book-Entry Transfer Facility, unless an Agent's
Message is received by the Exchange Agent, in compliance with ATOP, an
appropriate Letter of Transmittal properly completed and duly executed with any
required signature guarantee and all other required documents must in each case
be transmitted to and received or confirmed by the Exchange Agent at its address
set forth below on or prior to the Expiration Date, or, if the guaranteed
delivery procedures described below are complied with, within the time period
provided under such procedures.  Delivery of documents to the Book-Entry
Transfer Facility does not constitute delivery to the Exchange Agent.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes and withdrawal of tendered Old Notes
will be determined by the Company in its sole direction, which determination
will be final and binding.  The Company reserves the absolute right to reject
any and all Old Notes not properly tendered or any Old Notes the Company's
acceptance of which would, in the opinion of counsel for the Company, be
unlawful. The Company also reserves the right in its sole discretion to waive
any defects, irregularities or conditions of tender as to particular Old Notes.
The Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties.  Unless waived, any defects or irregularities in
connection with tenders of Old Notes must be cured within such time as the
Company shall determine. Although the Company intends to notify holders of
defects or irregularities with respect to tenders of Old Notes, neither the
Company, the Exchange Agent nor any other person shall incur any liability for
failure to give such notification. Tenders of Old Notes will not be deemed to
have been made until such defects or irregularities have been cured or waived.
Any Old Notes received by the Exchange Act that are not properly tendered and as
to which the defects or irregularities have not been cured or waived will be
returned by the Exchange Agent to the tendering holders, unless otherwise
provided in the Letter of Transmittal, as soon as practicable following the
Expiration Date.

GUARANTEED DELIVERY PROCEDURES

     Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent or (iii) who
cannot complete the procedures for book-entry transfer, prior to the Expiration
Date, may effect a tender if:

     a.   the tender is made through an Eligible Institution;

     b.   prior to the Expiration Date, the Exchange Agent receives from such
          Eligible Institution a properly completed and duly executed Notice of
          Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
          setting forth the name and address of the holder, the certificate
          number(s) of such Old Notes and the principal amount of Old Notes
          tendered, stating that the tender is being made thereby and
          guaranteeing that, within five New York Stock Exchange trading days
          after the Expiration Date, the Letter of Transmittal (or facsimile
          thereof) together with the certificate(s) representing the Old Notes
          (or a confirmation of book-entry transfer of such Notes into the
          Exchange Agent's account at the Book-Entry Transfer Facility), and any
          other documents required by the Letter of Transmittal will be
          deposited by the Eligible Institution with the Exchange Agent; and

     c.   such properly completed and executed Letter of Transmittal (or
          facsimile thereof), as well as the certificate(s) representing all
          tendered Old Notes in proper form for transfer (or a confirmation or
          book-entry transfer of such Old Notes into the Exchange Agent's
          account at the Book-Entry Transfer

                                      -64-
<PAGE>
 
          Facility), and all other documents required by the Letter of
          Transmittal are received by the Exchange Agent upon five New York
          Stock Exchange trading days after the Expiration Date.

     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Old Notes according to the guaranteed
delivery procedures set forth above.

WITHDRAWAL OF TENDERS

     Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date.

     To withdraw a tender of Old Notes in the Exchange Offer, a telegram, telex,
letter or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at its address set forth herein prior to 5:00 p.m., New York City
time, on the Expiration Date.  Any such notice of withdrawal must (i) specify
the name of the person having deposited the Old Nots to be withdrawn (the
"Depositor"); (ii) identify the Old Notes to be withdrawn (including the
certificate number(s) and principal amount of such Old Notes, or, in the case of
Old Notes transferred by book-entry transfer, the name and number of the account
at the Book-Entry Transfer Facility to be credited); (iii) be signed by the
holder in the same manner as the original signature on the Letter of Transmittal
by which such Old Notes were tendered (including any required signature
guarantees) or be accompanied by documents of transfer sufficient to have the
Trustee with respect to the Old Notes register the transfer of such Old Notes
into the name of the person withdrawing the tender and (iv) specify the name in
which any such Old Notes are to be registered, if different from that of the
Depositor.  All questions as to the validity, form and eligibility (including
time of receipt) of such notices will be determined by the Company, whose
determination shall be final and binding on all parties.  Any Old Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer and no New Notes will be issued with respect thereto unless the
Old Notes so withdrawn are validly retendered.  Any Old Notes which have been
tendered but which are not accepted for exchange will be returned to the holder
thereof without cost to such holder as soon as practicable after withdrawal,
rejection of tender or termination of the Exchange Offer.  Properly withdrawn
Old Notes may be retendered by following one of the procedures described above
under "-Procedures for Tendering" at any time prior to the Expiration Date.

CONDITIONS

     Notwithstanding any other term of the Exchange Offer, the Company will not
be required to accept for exchange, or exchange New Notes for, any Old Notes,
and may terminate or amend the Exchange Offer as provided herein before the
acceptance of such Old Notes if:

     (a)  any action or proceeding is instituted or threatened in any court or
          by or before any governmental agency with respect to the Exchange
          Offer which, in the reasonable judgment of the Company, might
          materially impair the ability of the Company to proceed with the
          Exchange Offer or any material adverse development has occurred in any
          existing action or proceeding with respect to the Company, or any of
          its subsidiaries; or

     (b)  any law, statute, rule, regulation or interpretation by the staff of
          the Commission is proposed, adopted or enacted, which, in the
          reasonable judgment of the Company, might materially impair the
          ability of the Company to proceed with Exchange Offer or materially
          impair the contemplated benefits of the Exchange Offer to the Company;
          or

     (c)  any governmental approval has not been obtained, which approval the
          Company, in its reasonable discretion, deems necessary for the
          consummation of the Exchange Offer as contemplated hereby.

                                      -65-
<PAGE>
 
     If the Company determines in its reasonable discretion that any of the
conditions are not satisfied, the Company may (i) refuse to accept any Old Notes
and return all tendered Old Notes to the tendering holder, (ii) extend the
Exchange Offer and retain all Old Notes tendered prior to the expiration of the
Exchange Offer, subject, however, to the rights of holders to withdraw such Old
Notes (see "-Withdrawal of Tenders") or (iii) waive such unsatisfied conditions
with respect to the Exchange Offer and accept all properly tendered Old Notes
which have not been withdrawn.

FEES AND EXPENSES

     The Company will bear the expense of soliciting tenders.  The principal
solicitation is being made by mail; however, additional solicitation may be made
by telegraph, telecopy, telephone or in person by officers and regular employees
of the Company and its affiliates.

     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to broker, dealers, or others
soliciting acceptances of the Exchange Offer.  The Company, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse it for its reasonable out-of-pocket expenses in connection therewith.

     The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company.  Such expenses include fees and expenses of the Exchange
Agent and Trustee, accounting and legal fees and printing costs, among others.

                                      -66-
<PAGE>
 
ACCOUNTING TREATMENT

     The New Notes will be recorded at the same carrying value as the Old Notes,
which is face value, as reflected in the Company's accounting records on the
date of exchange.  Accordingly, no gain or loss for accounting purposes will be
recognized by the Company. The expenses of the Exchange Offer will be expensed
over the term of the New Notes.

CONSEQUENCES OF FAILURE TO EXCHANGE

     The Old Notes that are not exchanged for New Notes pursuant to the Exchange
Offer will remain restricted securities.  Accordingly, such Old Notes may be
resold only (i) to the Company (upon redemption thereof or otherwise), (ii) so
long as the Old Notes are eligible for resale pursuant to Rule 144A, to a person
inside the United States whom the seller reasonably believes is a qualified
institutional buyer within the meaning of Rule 144A under the Securities Act in
a transaction meeting the requirements of Rule 144A, in accordance with Rule 144
under the Securities Act, or pursuant to another exemption from the registration
requirements of the Securities Act (and based upon an opinion of counsel
reasonably acceptable to the Company) , (iii) outside the United States to a
foreign person in a transaction meeting the requirements of Rule 904 under the
Securities Act, or (iv) pursuant to an effective registration statement under
the Securities Act, in each case in accordance with any applicable securities
laws of any state of the United States.

RESALE OF THE NEW NOTES

     Based on interpretations by the staff of the Commission set forth in no-
action letters issued to third parties, the Company believes that a holder or
other person who receives New Notes, whether or not such person is the holder
(other than a person that is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act) who receives New Notes in exchange for Old
Notes in the ordinary course of business, and who is not participating, does not
intend to participate, and has no arrangement or understanding with any person
to participate, in the distribution of the New Notes, will be allowed to resell
the New Notes to the public without further registration under the Securities
Act and without delivering to the purchasers of the New Notes a prospectus that
satisfies the requirements of Section 10 of the Securities Act.  However, if any
holder acquires New Notes in the Exchange Offer for the purpose of distributing
or participating in a distribution of the New Notes, such holder cannot rely on
the position of the staff or the Commission enunciated in such no-action letters
or any similar interpretive letters, and must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transaction, unless an exemption from registration is otherwise
available.  The Company has not sought, and does not intend to seek, its own no-
action letter, and there can be no assurance that the Staff of the Commission
would make a similar determination with respect to the Exchange Offer.  Further,
each Participating Broker-Dealer that receives New Notes for its own account in
exchange for Old Notes must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes.  The Company has agreed that for a
period of 180 days after the consummation of the Exchange Offer, it will make
this prospectus, as amended and supplemented, available to any Participating
Broker-Dealer for use in connection with any such resale.  In addition, until
___________________, 1998 (90 days from the date of this prospectus), all
dealers effecting transactions in the New Notes may be required to deliver a
prospectus.

     As contemplated by these no-action letters and the Registration Rights
Agreement, each holder accepting the Exchange Offer is required to represent to
the Company in the Letter of Transmittal that (i) any New Notes received by such
holder in the Exchange Offer will be acquired in the ordinary course of its
business; (ii) such holder has no arrangement or understanding with any person
to participate in the distribution of the New Notes within the meaning of the
Securities Act or resale of the New Notes in violation of the Securities Act;
(iii) if such holder is not a broker-dealer, that it is not engaged in, and does
not intend to engage in, the distribution of the New Notes; (iv) if such holder
is a broker-dealer that will receive the New Notes for its own account in
exchange for Notes that were acquired as a result of market making or other
trading activities, that it will deliver a prospectus, as required by law, in
connection with any resale of such New Notes, and (v) if such holder is an
affiliate, that it will comply with the registration and

                                      -67-
<PAGE>
 
prospectus delivery requirements of the Securities Act applicable to it.  As
indicated above, each Participating Broker-Dealer that receives a New Note for
its own account in exchange for Old Notes must acknowledge that it will deliver
a Prospectus in connection with any resale of such New Notes.  For a description
of the procedures for such resales by Participating Broker-Dealer, see "Plan of
Distribution."


                              DESCRIPTION OF NOTES

     Set forth below is a summary of certain provisions of the Notes. The Notes
will be issued pursuant to the Indenture. The following summaries of certain
provisions of the Indenture are summaries only, do not purport to be complete
and are qualified in their entirety by reference to all of the provisions of the
Indenture. Capitalized terms used herein and not otherwise defined shall have
the meanings assigned to them in the Indenture. Wherever particular provisions
of the Indenture are referred to in this summary, such provisions are
incorporated by reference as a part of the statements made and such statements
are qualified in their entirety by such reference. A copy of the form of
Indenture is available upon request. For purposes of this summary, the term
"Company" refers only to ClimaChem, Inc. and not to any of its Subsidiaries.
The Old Notes and the New Notes are sometimes referred to herein collectively as
the "Notes."  Any descriptions of the Notes presented in the future tense shall
refer to the New Notes, where appropriate.

GENERAL

     The terms of the New Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"), as in effect on the date of the Indenture.
The form and terms of the New Notes are the same as the form and terms of the
Old Notes (which they replace) except that (i) the New Notes bear a Series B
designation, (ii) the New Notes have been registered under the Securities Act
and, therefore, will not bear legends restricting the transfer thereof, and
(iii) the holder of New Notes will not be entitled to certain rights under the
Registration Rights Agreement, including the provisions providing for liquidated
damages in certain circumstances relating to the timing of the Exchange Offer,
which rights will terminate when the Exchange Offer is consummated.  The New
Notes are subject to all such terms, and holders of the New Notes are referred
to the Indenture and the Trust Indenture Act for a statement of such terms.

     The Notes will be senior, unsecured, general obligations of the Company,
ranking pari passu in right of payment with all other senior, unsecured
obligations of the Company. The Notes will be limited in aggregate principal
amount to $105 million. The Notes are jointly and severally irrevocably and
unconditionally guaranteed on a senior basis by each of the Company's present
Subsidiaries (other than EDNC) and all of its future Subsidiaries (the
"Guarantors"). The guarantees will rank pari passu in right of payment with all
other senior, unsecured obligations of the Guarantors. The obligations of each
Guarantor under its guarantee, however, are limited in a manner intended to
avoid it being deemed a fraudulent conveyance under applicable law; provided,
however, there are no assurances that the guarantees will not be limited as a
fraudulent conveyance under applicable law. See "Risk Factors - Fraudulent
Conveyance Considerations" and  "Certain Bankruptcy Limitations" below. The term
"Subsidiaries" as used herein, however, does not include Unrestricted
Subsidiaries. The Notes will be issued only in fully registered form, without
coupons, in denominations of $l,000 and integral multiples thereof.

     Separate financial statements of the Guarantors are not included herein
because such Guarantors are jointly and severally liable with respect to the
Company's obligations under the Indenture and the Notes, and the aggregate net
assets, earnings and equity of the Guarantors and the Company are substantially
equivalent to the net assets, earnings and equity of the Company on a
consolidated basis.

PRINCIPAL, MATURITY AND INTEREST

     The Notes will mature on December 1, 2007. The Notes will bear interest at
the rate per annum stated on the cover page hereof from the date of issuance or
from the most recent Interest Payment Date to which interest has been

                                      -68-
<PAGE>
 
paid or provided for, payable semi-annually on June 1 and December 1 of each
year, commencing June 1, 1998, to the Persons in whose names such Notes are
registered at the close of business on the May 15 or November 15 immediately
preceding such Interest Payment Date. Interest will be calculated on the basis
of a 360-day year consisting of twelve 30-day months.

     Principal of, premium, if any, and interest and Liquidated Damages, if any,
on the Notes will be payable, and the Notes may be presented for registration of
transfer or exchange, at the office or agency of the Company maintained for such
purpose, which office or agency shall be maintained in the Borough of Manhattan,
The City of New York, except as set forth below. At the option of the Company,
payment of interest may be made by check mailed to the Holders of the Notes at
the addresses set forth upon the registry books of the Company; provided that
all payments with respect to Global Notes and certificated Notes, the Holders of
which have given wire transfer instructions to the Company and the Paying Agent,
will be required to be made by wire transfers of immediately available funds to
the accounts specified by the Holders thereof. No service charge will be made
for any registration of transfer or exchange of Notes, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. Until otherwise designated by the
Company, the Company's office or agency will be the corporate trust office of
the Trustee presently located at the office of the Trustee in the Borough of
Manhattan, The City of New York.

HOLDING COMPANY STRUCTURE

     The Company is a holding company for its Subsidiaries, with no material
operations of its own.  Accordingly, the Company is dependent upon the
distribution of the earnings of its Subsidiaries, whether in the form of
dividends, advances or payments on account of intercompany obligations, to
service its debt obligations.  In addition, the claims of the Holders of the
Notes are subject to the prior payment of all secured indebtedness of the
Guarantors.  There can be no assurance that, after providing for all such
secured claims, there would be sufficient assets available from the Company and
its subsidiaries to satisfy the claims of the Holders of the Notes.  See "Risk
Factors - Substantial Coverage; Ability to Service Indebtedness."

CERTAIN BANKRUPTCY LIMITATIONS

     The Company is a holding company, conducting all of its business through
Subsidiaries, which have guaranteed or will guarantee the Company's obligations
with respect to the Notes (with the exception of EDNC), and Unrestricted
Subsidiaries. See "Risk Factors." Holders of the Notes will be direct creditors
of each Guarantor by virtue of its guarantee. Nonetheless, in the event of the
bankruptcy or financial difficulty of a Guarantor, such Guarantor's obligations
under its guarantee may be subject to review and avoidance under state and
federal fraudulent transfer laws. Among other things, such obligations may be
avoided if a court concludes that such obligations were incurred for less than
reasonably equivalent value or fair consideration at a time when the Guarantor
was insolvent, was rendered insolvent, or was left with inadequate capital to
conduct its business. A court would likely conclude that a Guarantor did not
receive reasonably equivalent value or fair consideration to the extent that the
aggregate amount of its liability on its guarantee exceeds the economic benefits
it receives in the Offering. The obligations of each Guarantor under its
guarantee will be limited in a manner intended to cause it not to be a
fraudulent conveyance under applicable law, although no assurance can be given
that a court would give the holder the benefit of such provision. See "Risk
Factors--Fraudulent Conveyance Considerations."

     If the obligations of a Guarantor under its guarantee were avoided, Holders
of Notes would have to look to the assets of any remaining Guarantors for
payment. There can be no assurance in that event that such assets would suffice
to pay the outstanding principal and interest on the Notes.

                                      -69-

OPTIONAL REDEMPTION

         The Company will not have the right to redeem any Notes prior to
December 1, 2002 (other than out of the Net Cash Proceeds of a Public Equity
Offering, as described in the next following paragraph). The Notes will be
redeemable for cash at the option of the Company, in whole or in part, at any
time on or after December 1, 2002, upon not less than 30 days nor more than 60
days notice to each holder of Notes, at the following redemption prices
(expressed as percentages of the principal amount) if redeemed during the 12-
month period commencing December 1 of the years indicated below, in each case
(subject to the right of Holders of record on a Record Date to receive interest
due on an Interest Payment Date that is on or prior to such Redemption Date)
together with accrued and unpaid interest and Liquidated Damages, if any,
thereon to the Redemption Date:

         Until December 1, 2000, upon a Public Equity Offering of common stock
of the Company for cash, up to $35 million aggregate principal amount of the
Notes may be redeemed at the option of the Company within 120 days of such
Public Equity Offering, on not less than 30 days, but not more than 60 days,
notice to each Holder of the Notes to be redeemed, with cash from the Net Cash
Proceeds of such Public Equity Offering, at 110.750% of principal (subject to
the right of Holders of record on a Record Date to receive interest due on an
Interest Payment Date that is on or prior to such Redemption Date) together with
accrued and unpaid interest and Liquidated Damages, if any, to the date of
redemption; provided, however, that immediately following such redemption not
less than $65 million aggregate principal amount of the Notes are outstanding.

         In the case of a partial redemption, the Trustee shall select the Notes
or portions thereof for redemption on a pro rata basis, by lot or in such other
manner it deems appropriate and fair. The Notes may be redeemed in part in
multiples of $1,000 only.

         The Notes will not have the benefit of any sinking fund.

         Notice of any redemption will be sent, by first class mail, at least 30
days and not more than 60 days prior to the date fixed for redemption to the
Holder of each Note to be redeemed to such Holder's last address as then shown
upon the registry books of the Registrar. Any notice which relates to a Note to
be redeemed in part only must state the portion of the principal amount equal to
the unredeemed portion thereof and must state that on and after the date of
redemption, upon surrender of such Note, a new Note or Notes in a principal
amount equal to the unredeemed portion thereof will be issued. On and after the
date of redemption, interest will cease to accrue on the Notes or portions
thereof called for redemption, unless the Company defaults in the payment
thereof.

CERTAIN COVENANTS

Repurchase of Notes at the Option of the Holder Upon a Change of Control

         The Indenture provides that in the event that a Change of Control has
occurred, each Holder of Notes will have the right, at such Holder's option,
pursuant to an irrevocable and unconditional offer by the Company (the "Change
of Control Offer"), to require the Company to repurchase all or any part of such
Holder's Notes (provided, that the principal amount of such Notes must be $1,000
or an integral multiple thereof) on a date (the "Change of Control Purchase
Date") that is no later than 35 Business Days after the occurrence of such
Change of Control, at a cash price equal to 101% of

                                      -70-
<PAGE>
 
the principal amount thereof (the "Change of Control Purchase Price"), together
with accrued and unpaid interest and Liquidated Damages, if any, to the Change
of Control Purchase Date. The Change of Control Offer shall be made within 10
Business Days following a Change of Control and shall remain open for 20
Business Days following its commencement (the "Change of Control Offer Period").
Upon expiration of the Change of Control Offer Period, the Company promptly
shall purchase all Notes properly tendered in response to the Change of Control
Offer.

         As used herein, a "Change of Control" means (i) any merger or
consolidation of any of the Company or LSB with or into any Person or any sale,
transfer or other conveyance, whether direct or indirect, of all or
substantially all of the assets of either of the Company or LSB, on a
consolidated basis, in one transaction or a series of related transactions, if,
immediately after giving effect to such transaction(s), any "Person" or "group"
(as such terms are used for purposes of Sections 13(d) and 14(d) of the Exchange
Act, whether or not applicable) (other than an Excluded Person) is or becomes
the "beneficial owner," directly or indirectly, of more than 50% of the total
voting power in the aggregate normally entitled to vote in the election of
directors, managers, or trustees, as applicable, of the transferee(s) or
surviving entity or entities, (ii) any "Person" or "group" (as such terms are
used for purposes of Sections 13(d) and 14(d) of the Exchange Act, whether or
not applicable) (other than an Excluded Person) is or becomes the "beneficial
owner," directly or indirectly, of more than 50% of the total voting power in
the aggregate of all classes of Capital Stock of either of the Company or LSB
then outstanding normally entitled to vote in elections of directors, or (iii)
during any period of 12 consecutive months after the Issue Date, individuals who
at the beginning of any such 12-month period constituted the Board of Directors
of LSB (together with any new directors whose election by such Board or whose
nomination for election by the shareholders of LSB was approved by a vote of a
majority of the directors then still in office who were either directors at the
beginning of such period or whose election or nomination for election was
previously so approved) cease for any reason to constitute a majority of the
Board of Directors of LSB then in office.

         On or before the Change of Control Purchase Date, the Company will (i)
accept for payment Notes or portions thereof properly tendered pursuant to the
Change of Control Offer, (ii) deposit with the Paying Agent cash sufficient to
pay the Change of Control Purchase Price (together with accrued and unpaid
interest and Liquidated Damages, if any) of all Notes so tendered and (iii)
deliver to the Trustee Notes so accepted together with an Officers' Certificate
listing the Notes or portions thereof being purchased by the Company. The Paying
Agent promptly will pay the Holders of Notes so accepted an amount equal to the
Change of Control Purchase Price (together with accrued and unpaid interest and
Liquidated Damages, if any), and the Trustee promptly will authenticate and
deliver to such Holders a new Note equal in principal amount to any unpurchased
portion of the Note surrendered. Any Notes not so accepted will be delivered
promptly by the Company to the Holder thereof. The Company publicly will
announce the results of the Change of Control Offer on or as soon as practicable
after the Change of Control Purchase Date.

         The Change of Control purchase feature of the Notes may make more
difficult or discourage a takeover of the Company or LSB, and, thus, the removal
of incumbent management.

         The phrase "all or substantially all" of the assets of the Company or
LSB, as the case may be, will likely be interpreted under applicable state law
and will be dependent upon particular facts and circumstances. As a result,
there may be a degree of uncertainty in ascertaining whether a sale or transfer
of "all or substantially all" of the assets or the Company or LSB, as the case
may be, has occurred.

         No assurances can be given that the Company will have available
sufficient funds to acquire Notes tendered upon the occurrence of a Change of
Control. In the event that the Company is required to purchase outstanding Notes
upon the occurrence of a Change of Control, the Company expects that it would
seek third party financing to the extent that it does not have available funds
to meet its purchase obligations. There can be no assurance that the Company
would be able to obtain such financing.

         Any Change of Control Offer will be made in compliance with all
applicable laws, rules and regulations, including, if applicable, Regulation 14E
under the Exchange Act and the rules thereunder and all other applicable Federal
and state securities laws. To the extent that the provisions of any securities
laws or regulations conflict with the

                                      -71-
<PAGE>
 
terms hereof, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under the
Indenture or the Notes by virtue thereof.

Limitation on Incurrence of Additional Indebtedness and Disqualified Capital
Stock

         The Indenture provides that, except as set forth in this covenant, the
Company and the Guarantors will not, and will not permit any of their
Subsidiaries to, directly or indirectly, issue, assume, guaranty, incur, become
directly or indirectly liable with respect to (including as a result of an
Acquisition), or otherwise become responsible for, contingently or otherwise
(individually and collectively, to "incur" or, as appropriate, an "incurrence"),
any Indebtedness or any Disqualified Capital Stock (including Acquired
Indebtedness) other than Permitted Indebtedness. Notwithstanding the foregoing,
if (i) no Default or Event of Default shall have occurred and be continuing at
the time of, or would occur after giving effect on a pro forma basis to, such
incurrence of Indebtedness or Disqualified Capital Stock and (ii) on the date of
such incurrence (the "Incurrence Date"), the Consolidated Coverage Ratio of the
Company for the Reference Period immediately preceding the Incurrence Date,
after giving effect on a pro forma basis to such incurrence of such Indebtedness
or Disqualified Capital Stock and, to the extent set forth in the definition of
Consolidated Coverage Ratio, the use of proceeds thereof, would be at least 2.0
to 1 or, for an Incurrence Date after January 1, 2000, at least 2.25 to 1 (each,
a "Debt Incurrence Ratio"), then the Company may incur such Indebtedness or
Disqualified Capital Stock and the Guarantors may incur such Indebtedness.

         Indebtedness or Disqualified Capital Stock of any Person which is
outstanding at the time such Person becomes a Subsidiary of the Company
(including upon designation of any subsidiary or other Person as a Subsidiary)
or is merged with or into or consolidated with the Company or a Subsidiary of
the Company shall be deemed to have been incurred at the time such Person
becomes such a Subsidiary of the Company or is merged with or into or
consolidated with the Company or a Subsidiary of the Company, as applicable.

Limitation on Restricted Payments

         The Indenture provides that the Company and the Guarantors will not,
and will not permit any of their Subsidiaries to, directly or indirectly, make
any Restricted Payment if, after giving effect to such Restricted Payment on a
pro forma basis, (1) a Default or an Event of Default shall have occurred and be
continuing, (2) the Company is not permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Debt Incurrence Ratio in the covenant
"Limitation on Incurrence of Additional Indebtedness and Disqualified Capital
Stock," or (3) the aggregate amount of all Restricted Payments made by the
Company and its Subsidiaries, including after giving effect to such proposed
Restricted Payment, from and after the Issue Date, would exceed the sum of (a)
50% of the aggregate Consolidated Net Income of the Company and its Consolidated
Subsidiaries for the period (taken as one accounting period), commencing on the
first day of the first full fiscal quarter commencing after the Issue Date, to
and including the last day of the fiscal quarter ended immediately prior to the
date of each such calculation (or, in the event Consolidated Net Income for such
period is a deficit, then minus 100% of such deficit), plus (b) the aggregate
Net Cash Proceeds received by the Company from the sale of its Qualified Capital
Stock (other than (i) to a Subsidiary of the Company and (ii) to the extent
applied in connection with a Qualified Exchange) after the Issue Date.

         The immediately preceding paragraph, however, will not prohibit (i)
payments to LSB pursuant to the Management Agreement, the Services Agreement and
the Tax Sharing Agreement, each as in effect on the Issue Date, (ii) a Qualified
Exchange or (iii) the payment of any dividend on Qualified Capital Stock within
60 days after the date of its declaration if such dividend could have been made
on the date of such declaration in compliance with the foregoing provisions. The
full amount of any Restricted Payment made pursuant to clause (iii) (but not
pursuant to clauses (i) and (ii)) of the immediately preceding sentence,
however, will be deducted in the calculation of the aggregate amount of
Restricted Payments available to be made referred to in clause (3) of the
immediately preceding paragraph.

                                      -72-

Limitation on Dividends and Other Payment Restrictions Affecting Subsidiaries

         The Indenture provides that the Company and the Guarantors will not,
and will not permit any of their Subsidiaries to, directly or indirectly,
create, assume or suffer to exist any consensual restriction on the ability of
any Subsidiary of the Company to pay dividends or make other distributions to or
on behalf of, or to pay any obligation to or on behalf of, or otherwise to
transfer assets or property to or on behalf of, or make or pay loans or advances
to or on behalf of, the Company or any Subsidiary of the Company, except (a)
restrictions imposed by the Notes or the Indenture, (b) restrictions imposed by
applicable law, (c) existing restrictions under specified Indebtedness
outstanding on the Issue Date, (d) restrictions under any Acquired Indebtedness
not incurred in violation of the Indenture or any agreement relating to any
property, asset, or business acquired by the Company or any of its Subsidiaries,
which restrictions in each case existed at the time of acquisition, were not put
in place in connection with or in anticipation of such acquisition and are not
applicable to any Person, other than the Person acquired, or to any property,
asset or business, other than the property, assets and business so acquired, (e)
any such restriction or requirement imposed by Indebtedness incurred under
paragraph (b) of the definition of "Permitted Indebtedness" provided such
restriction or requirement is no more restrictive than that imposed by the
Credit Agreement as of the Issue Date, (f) restrictions with respect solely to a
Subsidiary of the Company imposed pursuant to a binding agreement which has been
entered into for the sale or disposition of all or substantially all of the
Equity Interests or assets of such Subsidiary, provided such restrictions apply
solely to the Equity Interests or assets of such Subsidiary which are being
sold, and (g) in connection with and pursuant to permitted refinancings,
replacements of restrictions imposed pursuant to clauses (a), (c) or (d) of this
paragraph that are not more restrictive than those being replaced and do not
apply to any other Person or assets than those that would have been covered by
the restrictions in the Indebtedness so refinanced. Notwithstanding the
foregoing, neither (a) customary provisions restricting subletting or assignment
of any lease entered into in the ordinary course of business, consistent with
industry practice, nor (b) Liens permitted under the terms of the Indenture
shall in and of themselves be considered a restriction on the ability of the
applicable Subsidiary to transfer such agreement or assets, as the case may be.

Limitation on Liens Securing Indebtedness

         The Company and the Guarantors will not, and will not permit any of
their Subsidiaries to, create, incur, assume or suffer to exist any Lien of any
kind, other than Permitted Liens, upon any of their respective assets now owned
or acquired on or after the date of the Indenture or upon any income or profits
therefrom (any such Lien, the "Initial Lien"), unless the Company provides, and
causes its Subsidiaries to provide, concurrently therewith, that the Notes are
equally and ratably so secured, provided that, if such Indebtedness is
Subordinated Indebtedness, the Initial Lien securing such Subordinated
Indebtedness shall be subordinate and junior to the Lien securing the Notes with
the same relative priority as such Subordinated Indebtedness shall have with
respect to the Notes. Any such Lien thereby created in favor of the Notes will
be automatically and unconditionally released and discharged upon the release
and discharge of the Initial Lien to which it relates.

Limitation on Sale of Assets and Subsidiary Stock

         The Indenture provides that (except as otherwise provided herein) the
Company and the Guarantors will not, and will not permit any of their
Subsidiaries to convey, sell, transfer, assign or otherwise dispose of, directly
or indirectly, any of its property, business or assets, including by merger or
consolidation (in the case of a Guarantor or a Subsidiary of the Company), and
including any sale or other transfer or issuance of any Equity Interests of any
Subsidiary of the Company, whether by the Company or a Subsidiary or through the
issuance, sale or transfer of Equity Interests by a Subsidiary of the Company,
and including any sale and leaseback transaction, in a single transaction or
through a series of related transactions, (any of the foregoing, an "Asset
Sale"), unless (l)(a) within 270 days after the date of such Asset Sale, the Net
Cash Proceeds therefrom (the "Asset Sale Offer Amount") are applied to the
optional redemption of the Notes in accordance with the terms of the Indenture
or to the repurchase of the Notes pursuant to an irrevocable, unconditional cash
offer (the "Asset Sale Offer") to repurchase Notes at a purchase price of 100%
of

                                      -73-
<PAGE>
 
principal amount (the "Asset Sale Offer Price") together with accrued and unpaid
interest and Liquidated Damages, if any, to the date of payment, made within 240
days of such Asset Sale or (b) within 240 days following such Asset Sale, the
Asset Sale Offer Amount is (i) invested (or committed, pursuant to a binding
commitment subject only to reasonable, customary closing conditions, to be
invested, and in fact is so invested, within an additional 90 days) in assets
and property (other than notes, bonds, obligation and securities, except in
connection with the acquisition of a Wholly Owned Subsidiary) which in the good
faith reasonable judgment of the Board will immediately constitute or be a part
of a Related Business of the Company or such Subsidiary (if it continues to be a
Subsidiary) immediately following such transaction or (ii) used to reduce
Indebtedness permitted pursuant to paragraph (b) of the definition "Permitted
Indebtedness", (2) at least 85% of the total consideration received for such
Asset Sale or series of related Asset Sales consists of Cash or Cash
Equivalents, (3) no Default or Event of Default shall have occurred and be
continuing at the time of, or would occur after giving effect, on a pro forma
basis, to, such Asset Sale, and (4) the Board of Directors of the Company
determines in good faith that the Company or such Subsidiary, as applicable,
receives fair market value for such Asset Sale.

         The Indenture provides that an acquisition of Notes pursuant to an
Asset Sale Offer may be deferred until the accumulated Net Cash Proceeds from
Asset Sales not applied to the uses set forth in (l) above (the "Excess
Proceeds") exceeds $5 million and that each Asset Sale Offer shall remain open
for 20 Business Days following its commencement (the "Asset Sale Offer Period").
Upon expiration of the Asset Sale Offer Period, the Company shall apply the
Asset Sale Offer Amount plus an amount equal to accrued and unpaid interest and
Liquidated Damages, if any, to the purchase of all Notes properly tendered (on a
pro rata basis if the Asset Sale Offer Amount is insufficient to purchase all
Notes so tendered) at the Asset Sale Offer Price (together with accrued
interest). To the extent that the aggregate amount of Notes tendered pursuant to
an Asset Sale Offer is less than the Asset Sale Offer Amount, the Company may
use any remaining Net Cash Proceeds for general corporate purposes as otherwise
permitted by the Indenture and following each Asset Sale Offer the Excess
Proceeds amount shall be reset to zero. For purposes of (2) above, total
consideration received means the total consideration received for such Asset
Sales minus the amount of (a) Indebtedness which is not Subordinated
Indebtedness assumed by a transferee which assumption permanently reduces the
amount of Indebtedness outstanding on the Issue Date or permitted pursuant to
paragraph (d), (e) or (f) of the definition "Permitted Indebtedness" and (b)
property that within 30 days of such Asset Sale is converted into Cash or Cash
Equivalents).

     Notwithstanding the foregoing provisions of the prior two paragraphs:

     (i)     the Company and its Subsidiaries may, in the ordinary course of
             business, convey, sell, transfer, assign or otherwise dispose of
             inventory acquired and held for resale in the ordinary course of
             business;

     (ii)    the Company and its Subsidiaries may convey, sell, transfer, assign
             or otherwise dispose of accounts receivable and notes receivable
             consistent with past practice for face value;

     (iii)   the Company and its Subsidiaries may convey, sell, transfer, assign
             or otherwise dispose of assets pursuant to and in accordance with
             the covenant "Limitation on Merger, Sale or Consolidation";

     (iv)    the Company and its Subsidiaries may sell or dispose of damaged,
             worn out or other obsolete property in the ordinary course of
             business so long as such property is no longer necessary for the
             proper conduct of the business of the Company or such Subsidiary,
             as applicable;

     (v)     the Company and its Subsidiaries may convey, sell, transfer, assign
             or otherwise dispose of assets to the Company or any of its wholly
             owned Guarantors;

     (vi)    the Company and its Subsidiaries may grant Liens not prohibited by
             this Indenture; and

                                      -74-
<PAGE>
 
     (vii)   the Company and its Subsidiaries may convey, sell, transfer, assign
             or otherwise dispose of assets having a value of $1 million or less
             in a single transaction or a series of related transactions.

     All Net Cash Proceeds from an Event of Loss shall be invested in the
business of the Company, used for prepayment of Indebtedness, or used to
repurchase Notes, all within the period and as otherwise provided above in
clause 1(a) or 1(b) of the first paragraph of this section.

     In addition to the foregoing, the Company will not, and will not permit any
Subsidiary to, directly or indirectly make any Asset Sale of any of the Equity
Interests of any Subsidiary except (i) pursuant to an Asset Sale of all the
Equity Interests of such Subsidiary or (ii) pursuant to an Asset Sale of shares
of common stock of TES with no preferences or special rights or privileges and
with no redemption or prepayment privileges, provided that after such sale the
Company or its Subsidiaries own at least 50% of the voting and economic interest
of the Capital Stock of TES.

     Notwithstanding the foregoing provisions, the Company or TES may contribute
all or substantially all the assets or Equity Interests of TES to a joint
venture in which the Company or its Subsidiaries own no less than 50% of the
voting and economic interests.

     Any Asset Sale Offer shall be made in compliance with all applicable laws,
rules, and regulations, including, if applicable, Regulation 14E of the Exchange
Act and the rules thereunder and all other applicable Federal and state
securities laws. To the extent that the provisions of any securities laws or
regulations conflict with the terms hereof, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations hereunder by virtue thereof.

Limitation on Transactions with Affiliates

     The Indenture provides that neither the Company nor any of its Subsidiaries
will be permitted on or after the Issue Date to enter into or suffer to exist
any contract, agreement, arrangement or transaction with any Affiliate (an
"Affiliate Transaction"), or any series of related Affiliate Transactions,
(other than Exempted Affiliate Transactions) (i) unless it is determined that
the terms of such Affiliate Transaction are fair and reasonable to the Company,
and no less favorable to the Company than could have been obtained in an arm's
length transaction with a non-Affiliate, and (ii) if involving consideration to
either party in excess of $2.5 million, unless such Affiliate Transaction(s) is
evidenced by an Officers' Certificate addressed and delivered to the Trustee
certifying that such Affiliate Transaction (or Transactions) has been approved
by a majority of the members of the Board of Directors that are disinterested in
such transaction and (iii) if involving consideration to either party in excess
of $5 million, unless in addition the Company, prior to the consummation
thereof, obtains a written favorable opinion as to the fairness of such
transaction to the Company from a financial point of view from an accounting,
appraisal or investment banking firm of national reputation. A member of the
Board of Directors of the Company that is a non-employee director of LSB will be
deemed disinterested for purposes of this covenant. For purposes of compliance
with clauses (ii) and (iii) above, total consideration for a series of related
Affiliate Transactions involving purchases or sales entered into in the ordinary
course of business will only include purchases or sales made in the last twelve
months ended on the date of the most recent purchase.

Limitation on Merger, Sale or Consolidation

     The Indenture provides that the Company will not, directly or indirectly,
consolidate with or merge with or into another Person or sell, lease, convey or
transfer all or substantially all of its assets (computed on a consolidated
basis), whether in a single transaction or a series of related transactions, to
another Person or group of affiliated Persons or adopt a Plan of Liquidation,
unless (i) either (a) the Company is the continuing entity or (b) the resulting,
surviving or transferee entity or, in the case of a Plan of Liquidation, the
entity which receives the greatest value from such Plan of Liquidation is a
corporation organized under the laws of the United States, any state thereof or
the District of Columbia and expressly assumes by supplemental indenture all of
the obligations of the Company in connection with the Notes

                                      -75-
<PAGE>
 
and the Indenture; (ii) no Default or Event of Default shall exist or shall
occur immediately after giving effect on a pro forma basis to such transaction;
(iii) immediately after giving effect to such transaction on a pro forma basis,
the Consolidated Net Worth of the resulting, surviving or transferee entity or,
in the case of a Plan of Liquidation, the entity which receives the greatest
value from such Plan of Liquidation is at least equal to the Consolidated Net
Worth of the Company immediately prior to such transaction; and (iv) immediately
after giving effect to such transaction on a pro forma basis, the resulting,
surviving or transferee entity or, in the case of a Plan of Liquidation, the
entity which receives the greatest value from such Plan of Liquidation would
immediately thereafter be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Debt Incurrence Ratio set forth in the covenant
"Limitation on Incurrence of Additional Indebtedness and Disqualified Capital
Stock."

     Upon any consolidation or merger or any transfer of all or substantially
all of the assets of the Company or consummation of a Plan of Liquidation in
accordance with the foregoing, the successor corporation formed by such
consolidation or into which the Company is merged or to which such transfer is
made or, in the case of a Plan of Liquidation, the entity which receives the
greatest value from such Plan of Liquidation shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
the Indenture with the same effect as if such successor corporation had been
named therein as the Company, and the Company shall be released from the
obligations under the Notes and the Indenture except with respect to any
obligations that arise from, or are related to, such transaction.

     For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise) of all or substantially all of the properties and assets of one or
more Subsidiaries, the Company's interest in which constitutes all or
substantially all of the properties and assets of the Company shall be deemed to
be the transfer of all or substantially all of the properties and assets of the
Company.

Limitation on Lines of Business

     The Indenture provides that neither the Company nor any of its Subsidiaries
shall directly or indirectly engage to any substantial extent in any line or
lines of business activity other than that which, in the reasonable good faith
judgment of the Board of Directors of the Company, is a Related Business.

Future Subsidiary Guarantors

     The Indenture provides that all present Subsidiaries (except for EDNC) and
future Subsidiaries of the Company jointly and severally will guaranty
irrevocably and unconditionally all principal, premium, if any, and interest and
Liquidated Damages, if any, on the Notes on a senior basis.

Release of Guarantors

     The Indenture provides that no Guarantor shall consolidate or merge with or
into (whether or not such Guarantor is the surviving Person) another Person
unless (i) subject to the provisions of the following paragraph, the Person
formed by or surviving any such consolidation or merger (if other than such
Guarantor) assumes all the obligations of such Guarantor pursuant to a
supplemental indenture in form reasonably satisfactory to the Trustee, pursuant
to which such Person shall unconditionally guarantee, on a senior basis, all of
such Guarantor's obligations under such Guarantor's guarantee and the Indenture
on the terms set forth in the Indenture; and (ii) immediately before and
immediately after giving effect to such transaction on a pro forma basis, no
Default or Event of Default shall have occurred or be continuing.

     Upon the sale or disposition (whether by merger, stock purchase, asset sale
or otherwise) of a Guarantor or all or substantially all of its assets to an
entity which is not a Guarantor, which transaction is otherwise in compliance
with the Indenture (including, without limitation, the provisions of the
covenant "Limitations on Sale of Assets and Subsidiary Stock"), such Guarantor
will be deemed released from its obligations under its Guarantee of the Notes;

                                      -76-

provided, however, that any such termination shall occur only to the extent that
all obligations of such Guarantor under all of its guarantees of, and under all
of its pledges of assets or other security interests which secure, any
Indebtedness of the Company or any other Subsidiary shall also terminate upon
such release, sale or transfer.

Limitation on Status as Investment Company

     The Indenture prohibits the Company and its Subsidiaries from being
required to register as an "investment company" (as that term is defined in the
Investment Company Act of 1940, as amended), or from otherwise becoming subject
to regulation under the Investment Company Act.

Limitation on Sale and Leaseback Transactions

     The Indenture provides that the Company will not, and will not permit any
Subsidiary to, directly or indirectly, enter into any sale and leaseback
transaction unless (a) immediately after giving pro forma effect to such sale
and leaseback transaction (the Attributable Value of such sale and leaseback
transaction being deemed to be Indebtedness of the Company, if not otherwise
treated so pursuant to the definition of Indebtedness), the Company could incur
at least $1.00 of additional Indebtedness pursuant to the Debt Incurrence Ratio
set forth in the covenant "Limitation on Incurrence of Additional Indebtedness
and Disqualified Capital Stock" and (b) such sale and leaseback transaction
complies with the covenant "Limitation on Sale of Assets and Subsidiary Stock."

Payments for Consent

     Neither the Company nor any of its Subsidiaries shall, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any holder of any Notes for or as an inducement
to any consent, waiver or amendment of any of the terms or provisions of the
Indenture, the Notes or the Guarantees unless such consideration is offered to
be paid or agreed to be paid to all holders of the Notes who so consent, waive
or agree to amend in the time frame set forth in solicitation documents relating
to such consent, waiver or agreement, which solicitation documents will be
mailed to all Holders of the Notes a reasonable amount of time prior to the
expiration of such solicitation.

LSB Note

     In accordance with the terms of the Indenture, the Promissory Note, dated
November 26, 1997 (the "LSB Note"),  representing the $10 million of proceeds of
the Offering loaned to LSB  (i) bears interest at the rate of 10/3//4%, payable
semiannually on June 1 and December 1 of each year commencing June 1, 1998, (ii)
matures on December 1, 2007, (iii) is prepayable at par at any time prior to
maturity, (iv) is mandatorily prepayable with 50% of the net cash proceeds (net
of associated liabilities and expenses), within 30 days of the receipt of net
cash proceeds, from the sale of assets of LSB or its subsidiaries other than the
Company or subsidiaries of the Company (subject to certain customary exceptions
(including sales of inventory, accounts receivable and obsolete equipment),
currency exchangeability and transferability restrictions and an exception for
sales of assets having a value of $500,000 or less in a single transaction or
through a series of related transactions) to the extent that such net cash
proceeds are not used to prepay other senior indebtedness which requires such
prepayment under its terms, and (v) provides that the note may not be amended by
the Company without the consent of a majority aggregate principal amount of the
Notes then outstanding. The LSB Note will be a senior unsecured obligation of
LSB and will rank pari passu in right of payment will all existing and future
senior indebtedness of LSB.

REPORTS

     The Indenture provides that, whether or not the Company is subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company
shall deliver to the Trustee, to each Holder and to each prospective Holder who
so requests annual and quarterly financial statements substantially equivalent
to financial statements that

                                      -77-
<PAGE>
 
would have been included in reports filed with the Commission, if the Company
were subject to the requirements of Section 13 or 15(d) of the Exchange Act,
including, in each case, a management's discussion and analysis of financial
condition and results of operations and, with respect to annual information
only, a report thereon by the Company's certified independent public
accountants. In addition, the Company has agreed that it will file such reports
with the Commission, whether or not the Company is subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, provided the Commission
will accept such filings.

EVENTS OF DEFAULT AND REMEDIES

     The Indenture defines an Event of Default as:

     (i)     the failure by the Company to pay any installment of interest or
             Liquidated Damages on the Notes as and when the same becomes due
             and payable and the continuance of any such failure for 30 days,

     (ii)    the failure by the Company to pay all or any part of the principal,
             or premium, if any, on the Notes when and as the same becomes due
             and payable at maturity, redemption, by acceleration or otherwise,
             including, without limitation, payment of the Change of Control
             Purchase Price or the Asset Sale Offer Price, or otherwise,

     (iii)   the failure by the Company or any Subsidiary to observe or perform
             any other covenant or agreement contained in the Notes or the
             Indenture and the continuance of such failure for a period of 30
             days after written notice is given to the Company by the Trustee or
             to the Company and the Trustee by the Holders of at least 25% in
             aggregate principal amount of the Notes outstanding,

     (iv)    certain events of bankruptcy, insolvency or reorganization in
             respect of the Company or any of its Subsidiaries,

     (v)     a default in Indebtedness of the Company or any of its Subsidiaries
             with an aggregate principal amount in excess of $5 million at any
             one time (a) resulting from the failure to pay principal or
             interest or (b) as a result of which the maturity of such
             Indebtedness has been accelerated prior to its stated maturity, and

     (vi)    final unsatisfied judgments not covered by insurance aggregating in
             excess of $5 million, at any one time rendered against the Company
             or any of its Subsidiaries and not stayed, bonded or discharged
             within 60 days.

     The Indenture provides that if a Default occurs and is continuing, the
Trustee must, within 90 days after the occurrence of such Default, give to the
Holders notice of such Default.

     If an Event of Default occurs and is continuing (other than an Event of
Default specified in clause (iv), above, relating to the Company or any
Subsidiary), then in every such case, unless the principal of all of the Notes
shall have already become due and payable, either the Trustee or the Holders of
25% in aggregate principal amount of the Notes then outstanding, by notice in
writing to the Company (and to the Trustee if given by Holders) (an
"Acceleration Notice"), may declare all principal and premium, if any,
determined as set forth below, and accrued interest and Liquidated Damages, if
any, thereon to be due and payable immediately. If an Event of Default specified
in clause (iv), above, relating to the Company or any Subsidiary occurs, all
principal and premium, if any, and accrued interest and Liquidated Damages, if
any, thereon will be immediately due and payable on all outstanding Notes
without any declaration or other act on the part of Trustee or the Holders. The
Holders of a majority in aggregate principal amount of Notes generally are
authorized to rescind such acceleration if all existing Events of Default, other
than the non-payment of the principal of, premium, if any, and interest and
Liquidated Damages on the Notes which have become

                                      -78-
<PAGE>
 
due solely by such acceleration, have been cured or waived, except on default
with respect to any provision requiring a supermajority approval to amend, which
default may only be waived by such a supermajority.

     In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to
December 1, 2002 by reason of any willful action (or inaction) taken (or not
taken) by or on behalf of the Company with the intention of avoiding the
prohibition on redemption of the Notes prior to December 1, 2002, then the
premium specified in the Indenture shall also become immediately due and payable
to the extent permitted by law upon the acceleration of the Notes.

     Prior to the declaration of acceleration of the maturity of the Notes, the
Holders of a majority in aggregate principal amount of the Notes at the time
outstanding may waive on behalf of all the Holders any default, except a default
with respect to any provision requiring a supermajority approval to amend, which
default may only be waived by such a supermajority, and except a default in the
payment of principal of or interest on any Note not yet cured or a default with
respect to any covenant or provision which cannot be modified or amended without
the consent of the Holder of each outstanding Note affected. Subject to the
provisions of the Indenture relating to the duties of the Trustee, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request, order or direction of any of the Holders, unless such
Holders have offered to the Trustee reasonable security or indemnity. Subject to
all provisions of the Indenture and applicable law, the Holders of a majority in
aggregate principal amount of the Notes at the time outstanding will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee.

     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture and the Company is required, upon
becoming aware of any default or Event of Default, to deliver to the Trustee a
statement specifying such default or Event of Default.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     The Indenture provides that the Company may, at its option and at any time,
elect to have its obligations and the obligations of the Guarantors discharged
with respect to the outstanding Notes ("Legal Defeasance"). Such Legal
Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented, and the Indenture shall cease to be of
further effect as to all outstanding Notes and Guarantees, except as to (i)
rights of Holders to receive payments in respect of the principal of, premium,
if any, and interest on such Notes when such payments are due from the trust
funds; (ii) the Company's obligations with respect to such Notes concerning
issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or
stolen Notes, and the maintenance of an office or agency for payment and money
for security payments held in trust; (iii) the rights, powers, trust, duties,
and immunities of the Trustee, and the Company's obligations in connection
therewith; and (iv) the Legal Defeasance provisions of the Indenture. In
addition, the Company may, at its option and at any time, elect to have the
obligations of the Company and the Guarantors released with respect to certain
covenants that are described in the Indenture ("Covenant Defeasance") and
thereafter any omission to comply with such obligations shall not constitute a
Default or Event of Default with respect to the Notes. In the event Covenant
Defeasance occurs, certain events (not including nonpayment, nonpayment of
guarantees, bankruptcy, receivership, rehabilitation and insolvency events)
described under "Events of Default" will no longer constitute an Event of
Default with respect to the Notes.

     In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of the Notes, U.S. legal tender, U.S. Government Obligations or a
combination thereof, in such amounts as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants, to pay the
principal of, premium, if any, and interest and Liquidated Damages, if any, on
such Notes on the stated date for payment thereof or on the redemption date of
such principal or installment of

                                      -79-
<PAGE>
 
principal of, premium, if any, or interest or Liquidated Damages, if any, on
such Notes, and the Holders of Notes must have a valid, perfected, exclusive
security interest in such trust; (ii) in the case of the Legal Defeasance, the
Company shall have delivered to the Trustee an opinion of counsel in the United
States reasonably acceptable to Trustee confirming that (A) the Company has
received from, or there has been published by the Internal Revenue Service, a
ruling or (B) since the date of the Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such opinion of counsel shall confirm that, the Holders of such Notes
will not recognize income, gain or loss for federal income tax purposes as a
result of such Legal Defeasance and will be subject to federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such Legal Defeasance had not occurred; (iii) in the case of Covenant
Defeasance, the Company shall have delivered to the Trustee an opinion of
counsel in the United States reasonably acceptable to such Trustee confirming
that the Holders of such Notes will not recognize income, gain or loss for
federal income tax purposes as a result of such Covenant Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Covenant Defeasance had not
occurred; (iv) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit or, insofar as Events of Default from
bankruptcy or insolvency events are concerned, at any time in the period ending
on the 91st day after the date of deposit; (v) such Legal Defeasance or Covenant
Defeasance shall not result in a breach or violation of, or constitute a default
under, the Indenture or any other material agreement or instrument to which the
Company or any of its Subsidiaries is a party or by which the Company or any of
its Subsidiaries is bound; (vi) the Company shall have delivered to the Trustee
an Officers' Certificate stating that the deposit was not made by the Company
with the intent of preferring the holders of such Notes over any other creditors
of the Company or with the intent of defeating, hindering, delaying or
defrauding any other creditors of the Company or others; and (vii) the Company
shall have delivered to the Trustee an Officers' Certificate and an opinion of
counsel, each stating that the conditions precedent provided for in, in the case
of the Officers' Certificate, clauses (i) through (vi) and, in the case of the
opinion of counsel, clauses (i) (with respect to the validity and perfection of
the security interest), (ii), (iii) and (v) of this paragraph have been complied
with.

     If the funds deposited with the Trustee to effect Legal Defeasance or
Covenant Defeasance are insufficient to pay the principal of, premium, if any,
and interest on the Notes when due, then the obligations of the Company under
the Indenture will be revived and no such defeasance will be deemed to have
occurred.

AMENDMENTS AND SUPPLEMENTS

     The Indenture contains provisions permitting the Company, the Guarantors
and the Trustee to enter into a supplemental indenture for certain limited
purposes without the consent of the Holders. With the consent of the Holders of
not less than a majority in aggregate principal amount of the Notes at the time
outstanding, the Company, the Guarantors and the Trustee are permitted to amend
or supplement the Indenture or any supplemental indenture or modify the rights
of the Holders; provided that no such modification may without the consent of
Holders of at least 66 2/3% in aggregate principal amount of Notes at the time
outstanding modify the provisions (including the defined terms used therein) of
the covenant "Repurchase of Notes at the Option of the Holder upon a Change of
Control" and "Limitation on Sale of Assets and Subsidiary Stock" in a manner
adverse to the Holders and provided that no such modification may, without the
consent of each Holder affected thereby (i) change the Stated Maturity on any
Note, or reduce the principal amount thereof or the rate (or extend the time for
payment) of interest thereon or any premium payable upon the redemption thereof,
or change the place of payment where, or the coin or currency in which, any Note
or any premium or the interest thereon is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the Stated
Maturity thereof (or, in the case of redemption, on or after the Redemption
Date), or reduce the Change of Control Purchase Price or the Asset Sale Offer
Price or alter the provisions (including the defined terms used therein)
regarding the right of the Company to redeem the Notes in a manner adverse to
the Holders, or (ii) reduce the percentage in principal amount of the
outstanding Notes, the consent of whose Holders is required for any such
amendment, supplemental indenture or waiver provided for in the Indenture, or
(iii) modify any of the waiver provisions, except to increase any required
percentage or to provide that certain other provisions of the Indenture cannot
be modified or waived without the consent of the Holder of each outstanding Note
affected thereby, or (iv) cause the Notes or any Guarantee to become subordinate
in right of payment to any other Indebtedness.

                                      -80-
<PAGE>
 
NO PERSONAL LIABILITY OF PARTNERS, STOCKHOLDERS, OFFICERS, DIRECTORS

     The Indenture provides that no direct or indirect stockholder, employee,
officer or director, as such, past, present or future of the Company, the
Guarantors or any successor entity shall have any personal liability in respect
of the obligations of the Company or the Guarantors under the Indenture or the
Notes by reason of his or its status as such stockholder, employee, officer or
director, except to the extent such Person is the Company or a Guarantor.

BOOK-ENTRY, DELIVERY AND FORM

     The New Notes will be issued in fully registered form, without coupons, in
denominations of $1,000 principal amount and integral multiples thereof.

     Global Notes; Book-Entry Form. Except as set forth in the next paragraph,
the New Notes will initially be issued in the form of one or more global notes
(collectively, the "Global Note").  The Global Note will be deposited upon
issuance (the "Closing Date") with the trustee as custodian for The Depository
Trust Company, New York, New York ("DTC") and registered in the name of Cede &
Co. ("Cede") as DTC's nominee.

     Notes that were issued as described below under "Certificated Securities"
will be issued in the form of registered definitive certificates (the
"Certificated Securities").  Such Certificated Securities may, unless the Global
Note has previously been exchanged for Certificated Securities, the exchange by
a qualified institutional buyer for an interest in the Global Note representing
the principal amount of Notes being transferred.

     An investor may hold its interests in the Global Note directly through DTC
if such investor is a participant in DTC, or indirectly through organizations
which are participants in DTC (the "Participants"). Transfers between
Participants will be effected in the ordinary way in accordance with DTC rules
and will be settled in same-day funds. The laws of some states require that
certain Persons take physical delivery of securities in definitive form.
Consequently, the ability to transfer a beneficial interest in the Global Note
to such Person may be limited.

     Investors who are not Participants may beneficially own interests in the
Global Note held by DTC only through Participants, or certain banks, brokers,
dealers, trust companies and other parties that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly
("Indirect Participants"). So long as Cede, as nominee of DTC, is the registered
owner of the Global Note, Cede for all purposes will be considered the sole
holder of the Global Note. Except as provided below, owners of beneficial
interests in the Global Note will not be entitled to have certificates
registered in their names, will not receive or be entitled to receive physical
delivery of certificates in definitive form, and will not be considered holders
thereof.

     Payment of principal, redemption price and purchase price of, and interest
on the Global Note will be made to Cede, the nominee for DTC, as the registered
owner of the Global Note by wire transfer of immediately available funds. None
of the Company, the Trustee or any paying agent will have any responsibility or
liability for any aspect of the records relating to, or payments made on account
of, beneficial ownership interests in the Global Note or for maintaining,
supervising, or reviewing any records relating to such beneficial ownership
interests.

     The Company has been informed by DTC that, with respect to any payment of
principal, redemption price and purchase price of, and interest on the Global
Note, DTC's practice is to credit Participants' accounts on the payment date
therefor with payments in amounts proportionate to their respective beneficial
interests in the Notes represented by the Global Note, as shown on the records
of DTC, unless DTC has reason to believe that it will not receive payment on
such payment date. Payments by Participants to owners of beneficial interests in
Notes represented by the Global Note held through such Participants will be the
responsibility of such Participants, as is now the case with securities held for
the accounts of customers registered in "street name."

                                      -81-
<PAGE>
 
     Because DTC can only act on behalf of Participants, who in turn act on
behalf of Indirect Participants and certain banks, the ability of a Person
having a beneficial interest in Notes represented by the Global Note to pledge
such interest to Persons or entities that do not participate in the DTC system,
or otherwise take actions in respect of such interest, may be affected by the
lack of a physical certificate evidencing such interest.

     Neither the Company nor the Trustee (or any registrar or paying agent under
the Indenture) will have any responsibility for the performance by DTC or its
Participants or Indirect Participants of their respective obligations under the
rules and procedures governing their operations. DTC has advised the Company
that it will take any action permitted to be taken by a holder of Notes only at
the direction of one or more Participants to whose account with DTC interests in
the Global Note are credited and only in respect of the principal amount of the
Notes represented by the Global Note as to which such Participant or
Participants has or have given such direction.

     DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its Participants and to facilitate the clearance and settlement
of securities transactions between Participants through electronic book-entry
changes to the accounts of its Participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and may include
certain other organizations such as the Initial Purchaser. Certain of such
Participants (or their representatives), together with other entities, own DTC.
Indirect access to the DTC system is available to others such as banks, brokers,
dealers and trust companies that clear through, or maintain a custodial
relationship with, a Participant, either directly or indirectly.

     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Note among Participants of DTC, they are
under no obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. If DTC is at any time unwilling or
unable to continue as depositary and a successor depositary is not appointed by
the Company within 90 days, the Company will cause Notes to be issued in
definitive form in exchange for the Global Note. None of the Company, the
Trustee or any of their respective agents will have any responsibility for the
performance by DTS, their Participants or Indirect Participants of their
respective obligations under the rules and procedures governing their
operations, including maintaining, supervising or reviewing the records relating
to, or payments made on account of, beneficial ownership interests in Global
Note.

     Certificated Securities.  An investor may request that their Note be issued
in certificated form, and may request at any time that their interest in a
Global Note be exchanged for a Note in certificated form. Finally, certificated
Notes may be issued in exchange for Notes represented by the Global Note if no
successor depositary is appointed by the Company or in certain other
circumstances set forth in the Indenture.

     Same-Day Settlement and Payment.   The Indenture requires that payments in
respect of the Notes represented by the Global Note (including principal,
redemption price, purchase price and interest) be made by wire transfer of
immediately available funds to the accounts specified by Cede, the nominee for
DTC. With respect to certificated securities, the Company will make all payments
of principal, redemption price, purchase price and interest by wire transfer of
immediately available funds to the accounts specified by the holders thereof or,
if no such account is specified, by mailing a check to each such holder's
registered address. Secondary trading in long-term Notes and debentures of
corporate issuers not held in DTC is generally settled in clearing-house or
next-day funds. In contrast, the New Notes represented by the Global Note are
expected to be eligible to trade in the PORTAL Market and to trade in the
Depositary's Same-Day Funds Settlement System, and any permitted secondary
market trading activity in such Notes will, therefore, be required by the
Depositary to be settled in immediately available funds. The Company expects
that secondary trading in the certificated securities will also be settled in
immediately available funds.

CONCERNING THE TRUSTEE

     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise.  The Holders of a majority in principal amount
of the then outstanding Notes will have the right to direct the time, method and
place of conducting any proceeding for exercising any remedy available to the
Trustee, subject to certain exceptions.  The Indenture provides that in case of
Event of Default will occur (which will not be cured), the Trustee will be
required, in the exercise of its power, to use the same degree of care and skill
as a prudent person would exercise or use under the circumstances in the conduct
of his own affairs.  Subject to such provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request of any Holder of Notes, unless such Holder will have offered to the
Trustee  security and indemnity satisfactory to it against any loss, liability
or expense.

CERTAIN DEFINITIONS

                       DESCRIPTION OF OTHER INDEBTEDNESS

REVOLVING CREDIT FACILITY

     LSB, certain subsidiaries of LSB that are not subsidiaries of the Company,
and certain subsidiaries of the Company are parties to a $65 million Revolving
Credit Facility. The Revolving Credit Facility is evidenced by one loan
agreement for the Company's subsidiaries that are parties thereto and separate
loan agreements for LSB and its other subsidiaries that are not subsidiaries of
the Company.

     Under the terms of the Revolving Credit Facility, subsidiaries of the
Company may borrow up to $65 million on a revolving basis subject to limitations
based on (i) 85% of the amount of eligible receivables and 60% of the amount of
eligible inventory of such subsidiaries and (ii) the aggregate amount of
borrowings under the Revolving Credit Facility by LSB and certain subsidiaries
that are not subsidiaries of the Company. Under the Revolving Credit Facility,
LSB and certain subsidiaries of LSB that are not subsidiaries of the Company
have the right to borrow on a revolving basis up to $24 million. Any amounts so
borrowed by LSB and its subsidiaries that are not subsidiaries of the Company
will reduce the amount that the subsidiaries of the Company may borrow at any
one time under the Revolving Credit Facility. The Revolving Credit Facility, as
it relates to the subsidiaries of the Company, is secured by the accounts
receivable, inventory, proprietary rights, general intangibles, books and
records and proceeds thereof. All of the obligations under the Revolving Credit
Facility, including those of the Company's subsidiaries, are guaranteed and
cross-collateralized with certain assets by LSB. The Company has guaranteed only
the obligations of its subsidiaries under the Revolving Credit Facility, and
neither the Company nor its subsidiaries that are parties to the Revolving
Credit Facility have guaranteed the obligations of LSB and other subsidiaries of
LSB that are not subsidiaries of the Company under the Revolving Credit
Agreement. In addition, a default by LSB and its other subsidiaries that are not
subsidiaries of the Company under the Revolving Credit Facility will not be
considered a default of the Company's subsidiaries under the Revolving Credit
Facility. The agreement terminates on December 31, 2000, subject to automatic
renewal for terms of 13 months each thereafter, unless terminated by either
party.

     Borrowings under the Revolving Credit Facility bear an annual rate of
interest at a floating rate based on the lender's prime rate plus 1.5% per annum
or, at LSB's option, on the lender's LIBOR rate plus 3.875% per annum (which
rates are subject to increase or reduction upon achieving specified availability
and adjusted tangible net worth, as defined).

     The Revolving Credit Facility requires the Company to maintain certain
financial ratios (including adjusted tangible net worth and debt ratios), limits
the amount of capital expenditures, and contains other covenants which restrict,
among other things, (i) the incurrence of additional debt (other than as allowed
under the loan agreements); (ii) the payment of dividends and other
distributions in respect of capital stock of the Company; (iii) the making of
certain investments; (iv) certain mergers, acquisitions and dispositions; (v)
the issuance of secured guarantees; (vi) the granting of certain liens; and
(vii) prepayment of debt (including the Notes).

                                      -92-
<PAGE>
 
     Events of default under the Revolving Credit Facility include, among other
things, for both the Company or borrower (i) the failure to make payments of
principal, interest, and fees, when due; (ii) the inaccuracy of any
representation and warranty when made; (iii) the failure to perform covenants
contained therein; (iv) the occurrence of a change in control of LSB if any
party is or becomes the beneficial owner of more than 50% of the total voting
securities of LSB, except for Jack E. Golsen or members of his immediate family;
(v) default under any material agreement or instrument (other than an agreement
or instrument evidencing the lending of money) which would have a material
adverse effect on the Company or its subsidiaries which are borrowers under the
Revolving Credit Facility, taken as a whole; (vi) a default under any other
agreement relating to borrowed money exceeding certain limits; and (vii)
customary bankruptcy or insolvency defaults.

     The Company used a portion of the proceeds from the Initial Offering to
repay a substantial portion of the unpaid principal and accrued interest due by
certain of its subsidiaries under their previous revolving credit facility. See
"Use of Proceeds." The Company intends to continue to borrow, from time to time,
under the Revolving Credit Facility as the Company may deem appropriate to
finance the working capital requirements of the Company and its subsidiaries.

DSN LOANS

     DSN Corporation ("DSN"), a subsidiary of the Company, borrowed from an
unrelated lender approximately $18.8 million, which loans have an unpaid
balance, as of November  30, 1997, of approximately $13.7 million ("DSN Loans").
DSN has used the loan proceeds to acquire and/or construct assets for the
Chemical Business, including certain assets which are part of the Chemical
Business' El Dorado Facility. The proceeds of the DSN Loan were used to (i) buy
the assets relating to, and construct at, the Chemical Business' existing El
Dorado Facility, the DSN Plant, operated as part of the Chemical Business' El
Dorado Facility; (ii) construct the Wilmington Plant; and, (iii) purchase ten
rail cars ("10 Rail Cars"). Under the terms of the DSN Loan, DSN has granted to
the lender a lien, mortgage and security interest in and to (a) the DSN Plant,
including (i) the Ground Lease between DSN (as lessee) and Northwest Financial
Corporation ("Northwest"), a subsidiary of the Company (as lessor), in which DSN
leased approximately five acres of land at the El Dorado Facility, on which the
DSN Plant is located; (ii) the DSN Plant Ground Sublease between DSN (as lessor)
and EDC (as lessee), leasing to EDC the rights of DSN under the DSN Plant Ground
Lease; and (iii) the DSN Plant Equipment Lease between DSN (as lessor) and EDC
(as lessee), leasing to EDC the DSN Plant and the equipment now or hereafter
located at the DSN Plant or relating to the DSN Plant; (b) the Wilmington Plant,
including (i) the Wilmington Plant Equipment Lease between DSN (as lessor) and
EDC (as lessee), leasing to EDC the Wilmington Plant and the equipment located
thereon, (ii) the Wilmington Plant Ground Lease between DSN (as lessee) and an
unaffiliated corporation (as lessor), in which DSN leases approximately 10,000
square feet of land in North Carolina on which the Wilmington Plant is located,
(iii) the Wilmington Plant Land Sublease between DSN (as lessor) and EDC (as
lessee), leasing to EDC the rights of DSN under the Wilmington Plant Ground
Lease; (c) the 10 Rail Cars, including the Rail Car Lease between DSN (as
lessor) and EDC (as lessee), leasing to EDC the 10 Rail Cars, (d) general
intangibles, (e) equipment used in connection with, or in the conduct of, DSN's
business relating to the DSN Plant and the Wilmington Plant, (f) Consulting
Agreements between DSN and EDC whereby EDC has agreed to pay to DSN certain
amounts for providing consulting work for EDC, (g) proceeds relating to the
above, and (h) books and records of DSN regarding the above.

     The DSN Loans are each for a term of seven years commencing in 1995, with
the DSN Loans bearing an annual rate of interest ranging from 8.2% to 8.9% per
annum. Principal and interest on the DSN Loans are payable monthly. The DSN
Loans contain covenants (i) requiring maintenance of an escalating tangible net
worth of the Company, (ii) restricting distributions and dividends by DSN to the
Company to 50% of DSN's annual net income, (iii) restricting a change of control
of the Company and (iv) requiring maintenance of a debt to tangible net worth
ratio. The payment and performance of the DSN Loans are unconditionally
guaranteed by the Company. Each DSN Loan is subject to cross-collateralization
provisions with respect to the other DSN Loans. See "Business--Chemical
Business--DSN Plant."

TES REVOLVING FACILITY

     TES, the Australian subsidiary of the Company, has an AUS$8.5 million
(approximately US$5.8 million) revolving credit facility (the "TES Revolving
Facility"), which is evidenced by a loan agreement (the "TES Revolving Facility
Agreement") with Bank of New Zealand, Australia ("BNZA"). Based on the effective
exchange rate at November 30, 1997, approximately US$3.3 million (AUS$4.9
million) was borrowed under this facility. The TES Revolving Facility is secured
by a first lien on the assets, rights, and undertakings of TES and the wholly
owned subsidiaries of TES, T.E.S. Mining Services, Pty. Ltd. ("TES Mining") and
Total Energy Systems (NZ), Ltd. ("TES (NZ)"). In addition, LSB, TES Mining, and
TES (NZ) each unconditionally guarantee payment under the TES Revolving
Facility.

     Borrowings under the TES Revolving Facility bear varying rates of interest,
which had a weighted average of 7.1% at November 30, 1997. The TES Revolving
Facility does not have a stated term but is reviewed periodically by BNZA, which
reserves the right to continue the TES Revolving Facility at BNZA's discretion
on terms and conditions satisfactory to BNZA following the periodic review. TES
is currently negotiating with BNZA to increase the limit on borrowings under the
TES Revolving Facility to AUS$11.0 million (approximately US$7.5 million). TES
anticipates that if the TES Revolving Facility is so amended, future borrowings
under the TES Revolving Facility will be subject to terms similar to existing
terms. There can be no assurance that the limit on borrowings under the TES
Revolving Facility will be increased.

     The TES Revolving Facility Agreement (i) requires TES to maintain certain
financial ratios, (ii) limits the incurrence of additional debt  (other than as
expressly allowed), (iii) requires the trade debt of EDC to be subordinated to
the TES Revolving Facility, and (iv) restricts dividends and other distributions
on TES' capital stock. TES is in technical non-compliance with a certain
financial covenant contained in the loan agreement involving the TES Revolving
Facility. However, this covenant was not met at the time of closing of this loan
and BNZA has continued to extend credit under the TES Revolving Facility. The
outstanding borrowing under the TES Revolving Facility at September 30, 1997,
has been classified as due within one year in the accompanying consolidated
financial statements.

     The Company used a portion of the proceeds from the Initial Offering to
reduce the amounts owing by TES under the TES Revolving Facility. See "Use of
Proceeds." The Company has maintained the TES Revolving Facility in place and
intends to continue to borrow, from time to time, under the terms thereof as TES
or the Company may deem appropriate to finance the working capital requirements
of TES and its subsidiaries. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

TES CAPITALIZED LEASES

     TES has secured borrowings under a number of capitalized lease agreements
with various lenders (the "TES Capitalized Leases"). Under the terms thereof,
TES may, from time to time, lease equipment to be used in its business. TES has
the right to purchase the equipment under the Purchase Agreements for an amount
equal to the balance originally payable under the Purchase Agreement less
certain rebate amounts. Until purchased by TES, the equipment acquired by TES
remains the property of the lender. Each TES Capitalized Lease is for a term of
five years and is payable in monthly payments with the outstanding principal
balance due under the TES Capitalized Leases as of November 30, 1997, being
approximately US$2.2 million.

IEC AND CM EQUIPMENT FINANCING

     CM is a party to five Equipment Purchase and Security Agreements, each
dated February 1994, pursuant to which CM financed the purchase price of certain
equipment totaling $2 million (the "CM Equipment Financing"). Each of the
foregoing Equipment Purchase and Security Agreements (a) provides for the
repayment of the purchase price over

                                      -94-
<PAGE>
 
a term of five years at an interest rate of 8.5% and (b) is secured by the
related equipment. As of November 30, 1997, the outstanding principal balance of
the CM Equipment Financing is approximately $590,000

     Under a loan agreement dated July 1997, IEC financed $587,000, being the
purchase price of certain equipment over a term of four years at an interest
rate of 10% per annum (the "IEC Equipment Financing"). Such loan is secured by
the equipment so purchased and has an outstanding principal balance as of
November 30, 1997, of approximately $536,000. Under a loan agreement dated March
1995, IEC financed $1.5 million, being the purchase price of certain equipment,
for a term of five years at a variable interest rate equal to the 30-day
commercial paper rate plus 2.45% per annum, which loan has an outstanding
principal balance as of November 30, 1997, of approximately $700,000. Each of
the foregoing loans is secured by the equipment purchased with the proceeds of
such loan. In addition, IEC has leased certain equipment under a lease-purchase
agreement, dated April 1996, which provides for the payment of $960,000 over a
term of five years at an interest rate of approximately 7%, in which LSB
guaranteed the payment of such lease payments, and has an outstanding principal
balance of $614,000 as of November 30, 1997.

CM LOAN

     In July 1989, CM entered into a loan agreement (the "CM Loan") with the
Oklahoma County Financing Authority ("OCFA"), whereby the OCFA loaned to CM $2
million. The loan is due on August 1, 2004, and bears interest at a variable
rate equal to 3% plus the current rate under the State of Oklahoma $10 million
Taxable General Industrial Finance Bonds, Series P, with the minimum rate being
10% and the maximum rate being equal to the highest Oklahoma statutory rate. The
loan is secured by a mortgage on all of CM's interest in the lease covering CM's
facility in Oklahoma City, Oklahoma, and certain equipment located on such
property. LSB has unconditionally guaranteed the repayment of such loan. As of
November 30, 1997, the outstanding principal balance of this loan was
approximately $1.3 million.
 

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following discussion is based upon current provisions of the Internal
Revenue Code of 1986, as amended, applicable Treasury regulations, judicial
authority and administrative rulings and practice.  There can be no assurance
that the Internal Revenue Service (the "Service") will not take a contrary view,
and no ruling from the Service has been or will be sought.  Legislative,
judicial or administrative changes or interpretations may be forthcoming that
could alter or modify the statements and conditions set forth herein.  Any such
changes or interpretations may or may not be retroactive and could affect the
tax consequences to holders.  Certain holders (including insurance companies,
tax exempt organizations, financial institutions, broker-dealers, foreign
corporations and persons who are not citizens or residents of the United States)
may be subject to special rules not discussed below.  The Company recommends
that each holder consult such holder's own tax advisor as to the particular tax
consequences of exchanging such holder's Old Notes for New Notes, including the
applicability and effect of any state, local or foreign tax laws.

THE EXCHANGE

     The Company believes that the exchange of Old Notes for New Notes pursuant
to the Exchange Offer will not be treated as an "exchange" for federal income
tax purposes because the New Notes will not be considered to differ materially
in kind or extent from the Old Notes.  Rather, the New Notes received by a
holder will be treated as a continuation of the Old Notes in the hands of such
holder.  As a result, there will be no federal income tax consequences to
holders exchanging Old Notes for New Notes pursuant to the Exchange Offer.

THE NEW NOTES

     Interest Payments on the New Notes. The Old Notes and the New Notes are
debt for Federal income tax purposes. The Old Notes were not issued with
original issue discount. The stated interest on the Initial Notes and New

                                      -95-
<PAGE>
 
Notes should be considered to be "qualified stated interest" and, therefore,
will be includible in a holder's gross income (except to the extent attributable
to accrued interest at the time of purchase) as ordinary interest income for
federal income tax purposes in accordance with a holder's tax method of
accounting. If Liquidated Damages are paid (in addition to the accrual of
interest) on the Old Notes as described above under "The Exchange Offer; Purpose
and Effect of the Exchange Offer" such Liquidated Damages payments generally
should be includable in the Holder's gross income as ordinary income when such
payment is made.

     Tax Basis. A holder's adjusted tax basis (determined by taking into account
accrued interest at the time of purchase) in a New Note received in exchange for
an Old Note will equal the cost of the Old Note to such holder, increased by the
amounts of market discount previously included in income by the holder and
reduced by any principal payments received by such holder with respect to the
New Notes and by amortized bond premium. A holder's adjusted tax basis in a New
Note purchased by such holder will be equal to the price paid for such New Note
(determined by taking into account accrued interest at the time of purchase),
increased by market discount previously included in income by the holder and
reduced by any principal payments received by such holder with respect to a New
Note and by amortized bond premium. See "Market Discount and Bond Premium"
below.

     Sale, Exchange or Retirement. Upon the sale, exchange or retirement of a
New Note, a holder will recognize taxable gain or loss, if any, equal to the
difference between the amount realized on the sale, exchange or retirement and
such holder's adjusted tax basis in such New Note. Such gain or loss will be a
capital gain or loss (except to the extent of any accrued market discount), and
will be a (i) mid-term capital gain or loss if the New Note has been held for
more than 12 months but not more than 18 months at the time of such sale,
exchange or retirement, or (ii) long-term capital gain or loss if the New Note
has been held more than 18 months at the time of such sale, exchange or
retirement.

     Market Discount and Bond Premium. Holders should be aware that the market
discount provisions of the Code may affect the New Notes. These rules generally
provide that a holder who purchases New Notes for an amount which is less than
their principal amount will be considered to have purchased the New Notes at a
"market discount" equal to the amount of such difference. Such holder will be
required to treat any gain realized upon the disposition of the New Note as
interest income to the extent of the market discount that is treated as having
accrued during the period that such holder held such New Note, unless an
election is made to include such market discount in income on a current basis. A
holder of a New Note who acquires the New Note at a market discount and who does
not elect to include market discount in income on a current basis may also be
required to defer the deduction of a portion of the interest on any indebtedness
incurred or continued to purchase or carry the New Note until the holder
disposes of such New Note in a taxable transaction.

     If a holder's tax basis in a New Note immediately after acquisition exceeds
the stated redemption price at maturity of such New Note, such holder may be
eligible to elect to deduct such excess as amortizable bond premium pursuant to
Section 171 of the Code.

     Purchasers of the New Notes should consult their own tax advisors as to the
application to such purchasers of the market discount and bond premium rules.

     HOLDERS OF THE OLD NOTES ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING
THE PARTICULAR TAX CONSEQUENCES TO THEM OF ACQUIRING, OWNING OR DISPOSING OF THE
OLD NOTES AND THE NEW NOTES, INCLUDING THE APPLICATION OF FEDERAL, STATE, LOCAL
AND FOREIGN TAX LAWS, AND POSSIBLE FUTURE CHANGES IN SUCH FEDERAL TAX LAWS.


                              PLAN OF DISTRIBUTION

     Based on interpretations by the staff of the Commission set forth in no-
action letters issued to third parties, the Company believes that a holder or
other person who receives New Notes, whether or not such person is the holder
(other

                                      -96-
<PAGE>
 
than a person that is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act) who receives New Notes in exchange for Old Notes
in the ordinary course of business, and who is not participating, does not
intend to participate, and has no arrangement or understanding with any person
to participate, in the distribution of the New Notes, will be allowed to resell
the New Notes to the public without further registration under the Securities
Act and without delivering to the purchasers of the New Notes a prospectus that
satisfies the requirements of Section 10 of the Securities Act.  However, if any
holder acquires New Notes in the Exchange Offer for the purpose of distributing
or participating in a distribution of the New Notes, such holder cannot rely on
the position of the staff or the Commission enunciated in such no-action letters
or any similar interpretive letters, and must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transaction, unless an exemption from registration is otherwise
available.  Further, each Participating Broker-Dealer that receives New Notes
for its own account in exchange for Old Notes must acknowledge that it will
deliver a Prospectus in connection with any resale of such New Notes.  The
Company has agreed that for a period of 180 days after the consummation of the
Exchange Offer, it will make this prospectus, as amended and supplemented,
available to any participating broker-dealer for use in connection with any such
resale.  In addition, until ___________________, 1998 (90 days from the date of
this Prospectus), all dealers effecting transactions in the New Notes may be
required to deliver a prospectus.

     As contemplated by these no-action letters and the Registration Rights
Agreement, each holder accepting the Exchange Offer is required to represent to
the Company in the Letter of Transmittal that (i) any New Notes received by such
holder in the Exchange Offer will be acquired in the ordinary course of its
business; (ii) such holder has no arrangement or understanding with any person
to participate in the distribution of the New Notes within the meaning of the
Securities Act or resale of the New Notes in violation of the Securities Act;
(iii) if such holder is not a broker-dealer, that is not engaged in, and does
not intend to engage in, the distribution of the New Notes; (iv) if such holder
is a broker-dealer that will receive the New Notes for its own account in
exchange for Notes that were acquired as a result of market making or other
trading activities, that it will deliver a prospectus, as required by law, in
connection with any resale of such New Notes, (v) if such holder is an
affiliate, that it will comply with the registration and prospectus delivery
requirements of the Securities Act applicable to it.  However, the Company has
not sought, and does not intend to seek, its own no-action letter, and there can
be no assurance that the Staff of the Commission would make a similar
determination with respect to the Exchange Offer.  As indicated above, each
Participating Broker-Dealer that receives a New Note for its own account in
exchange for Old Notes must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes.

     The Company will not receive any proceeds from any sales of the New Notes
by Participating Broker-Dealers. New Notes received by Participating Broker-
Dealers for their own accounts pursuant to the Exchange Offer may be sold from
time to time in one or more transactions in the over-the counter market, in
negotiated transactions, through the writing of options on the New Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices.  Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such Participating Broker-Dealer and/or the purchasers of
any such New Notes.  Any Participating Broker-Dealer that resells the New Notes
that were received by it for its own account pursuant to the Exchange Offer and
any broker or dealer that participates in a distribution of such New Notes may
be deemed to be an "underwriter" within the meaning of the Securities Act and
any profit on any such resale of New Notes and any commissions or concessions
received by any such persons may be deemed to be underwriting compensation under
the Securities Act. The Letter of Transmittal states that by acknowledging that
it will deliver and by delivering a prospectus, a Participating Broker-Dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.

     For a period of 180 days from the consummation of the Exchange Offer, the

                        REPORT OF INDEPENDENT AUDITORS



The Board of Directors and Stockholders
ClimaChem, Inc.

     We have audited the accompanying consolidated balance sheets of ClimaChem,
Inc. as of December 31, 1995 and 1996, and the related consolidated statements
of operations and retained earnings and cash flows for each of the three years
in the period ended December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
ClimaChem, Inc. at December 31, 1995 and 1996, and the consolidated results of
its operations and its cash flows for each of the three years in the period
ended December 31, 1996, in conformity with generally accepted accounting
principles.

1.   BASIS OF PRESENTATION

     ClimaChem, Inc. (the "Company"), a wholly-owned subsidiary of LSB
Industries, Inc. ("LSB" or "Parent"), was organized under the laws of the State
of Oklahoma in October 1997. The Company's Certificate of Incorporation
authorizes the issuance of 500,000 shares of $.10 par value common stock. Prior
years' authorized, issued and outstanding shares of common stock in the
accompanying consolidated financial statements reflect this issuance as though
it occurred at the earliest period presented. The Company is a holding company
which maintains operations through various wholly-owned subsidiaries. The
Company owns, through its subsidiaries, a substantial portion, but not all, of
the operations comprising the Chemical Business and Climate Control Business as
previously owned by LSB. Prior to November 21, 1997, all of the Company's
subsidiaries were wholly-owned subsidiaries of LSB, directly or through one or
more intermediaries, and were contributed to the Company, following its
formation, by LSB or other subsidiaries in exchange for all of the outstanding
common stock of the Company. These exchanges have been accounted for as a
reorganization of entities under common control and, accordingly, reflect LSB's
and its subsidiaries' historical cost of such subsidiaries and net assets.
Accordingly, the consolidated financial statements of ClimaChem, Inc. and its
subsidiaries for all periods reflect this reorganization in a manner similar to
a pooling of interests.

     The consolidated financial statements include the accounts of ClimaChem,
Inc. and its wholly-owned subsidiaries. All significant intercompany
transactions have been eliminated in the accompanying financial statements.

     The Company has historically had significant transactions with LSB and its
subsidiaries which are reflected in the accompanying financial statements on the
basis established between the Company and LSB and its subsidiaries. See Notes 3,
7 and 9.

2.   ACCOUNTING POLICIES

  Use of Estimates

     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

  Statements of Cash Flows

     For purposes of reporting cash flows, cash and cash equivalents include
cash, overnight funds and interest bearing deposits with maturities when
purchased by the Company of 90 days or less.

  Inventories

     Inventory is priced at the lower of cost or market, with cost being
determined using the first-in, first-out (FIFO) basis, except for certain heat
pump products with a value of $5,981,000, $8,595,000 and $9,814,000 at December
31, 1995, 1996 and September 30, 1997, respectively, which are priced at the
lower of cost or market, with cost being determined using the last-in, first-out
(LIFO) basis. The difference between the LIFO basis and current cost is not
material at December 31, 1995 or 1996 or September 30, 1997.

  Depreciation

     For financial reporting purposes, depreciation, depletion and amortization
is primarily computed using the straight-line method over the estimated useful
lives of the assets.

  Excess of Purchase Price Over Net Assets Acquired

     The excess of purchase price over net assets acquired totaling $4,059,834,
$3,677,375 and $3,364,769, net of accumulated amortization, of $2,903,602,
$3,286,061 and $3,598,667 at December 31, 1995 and 1996 and September 30, 1997,
respectively, is included in other assets and is being amortized by the 
straight-line method over periods of 10 to 22 years. The carrying value of the
excess of purchase price over net assets acquired is reviewed (using estimated
future net cash flows, including expected proceeds from disposal) if the facts
and circumstances indicate that it may be impaired. No impairment provisions
were required in 1994, 1995, 1996 or the nine months ended September 30, 1997.

2.   ACCOUNTING POLICIES--(CONTINUED)

  Income Taxes

     Taxable income of the Company is included in the consolidated federal
income tax return of LSB. The provision for or benefit from income taxes is
calculated as if the Company filed a separate federal income tax return. To the
extent a state or other taxing jurisdiction requires or permits a consolidated,
combined, or unitary tax return to be filed, and such return includes the
Company, the principles expressed with respect to consolidated federal income
tax allocation shall apply.

     Deferred income taxes result from the Company having different bases for
financial and income tax reporting principally from utilizing different lives
for income taxes purposes than for financial reporting purposes.

  Research and Development Costs

     Costs incurred in connection with product research and development are
expensed as incurred. Such costs amounted to $557,000, $479,000 and $514,000 for
the years ended December 31, 1994, 1995 and 1996 and $407,000 and $305,000 for
the nine months ended September 30, 1996 and 1997, respectively.

  Advertising Costs

     Costs incurred in connection with advertising and promotion of the
Company's products are expensed as incurred. Such costs amounted to $982,000,
$898,000 and $893,000 for the years ended December 31, 1994, 1995 and 1996 and
$667,000 and $775,000 for the nine months ended September 30, 1996 and 1997,
respectively.

  Capitalized Interest

     Interest costs of $491,000, $1,357,000 and $2,405,000 related to the
construction of a new nitric acid plant were capitalized for the years ended
December 31, 1994, 1995 and 1996 and $1,762,000 and $1,113,000 for the nine
months ended September 30, 1996 and 1997, respectively, and are being amortized
over the related plant's estimated useful life.

  Translation of Foreign Currency

     Assets and liabilities of foreign operations, where the functional currency
is the local currency, are translated into U.S. dollars at the fiscal year end
exchange rate. The related translation adjustments are recorded as cumulative
translation adjustments, a separate component of shareholders' equity. Revenues
and expenses are translated using average exchange rates prevailing during the
year.

  Hedging

     In 1997, the Company entered into an interest rate forward agreement to
effectively fix the interest rate on a long-term lease commitment to become
effective August 1998 (not for trading purposes). The Company accounts for this
agreement under the deferral method, whereby the net gain or loss upon
settlement will serve to adjust the item being hedged, the minimum lease rentals
in periods commencing with the lease execution. If the necessary correlation
(generally a correlation coefficient of between 80% and 125%) ceases, the
differential between the market value and the carrying value will be recognized
in operations as a gain or loss. Under the interest rate forward agreement, the

2.   ACCOUNTING POLICIES--(CONTINUED)

Company is the fixed rate payor on notional amounts aggregating $50 million with
a weighted average interest rate of 7.12%.  The agreement requires a net
settlement on maturity in August 1998, of which an unrelated third party is
contractually obligated for 50%.  As of September 30, 1997, the financial
instruments' fair value (which is not reflected on the accompanying balance
sheet), net to the Company's 50% interest, represented a liability of
approximately $1.2 million.  A change in the settlement index (the ten year U.
S. Treasury bond) of .25% will change the fair value of the hedge agreement by
approximately $350,000, net to the Company's interest.

  Unaudited Financial Statements

     The accompanying unaudited financial statements include all adjustments,
consisting of normal, recurring accruals, which the Company considers necessary
for a fair presentation of the financial position and the results of operations
for the indicated periods. The results of operations for the nine months ended
September 30, 1997, are not necessarily indicative of the results to be expected
for the full year ending December 31, 1997.

3.   TRANSACTIONS WITH RELATED PARTIES

     On November 21, 1997, the Company and LSB entered into a services agreement
(the "Services Agreement") pursuant to which LSB will continue to provide to
the Company various services, including financial and accounting, order entry,
billing, credit, payable, insurance, legal, human resources, advertising and
marketing, and related administrative and management services, that LSB has
historically provided to the operations and businesses of the Company. The
Company will pay to, or reimburse, LSB for the costs and expenses incurred by
LSB in the performance of the Services Agreement.

     Under the terms of the Services Agreement, the Company will pay to, or
reimburse, LSB for the value of the office facilities of LSB, including LSB's
principal offices and financial accounting offices utilized in the performance
of the Services Agreement. LSB will determine the proportionate usage of such
facilities by LSB and the Company, and the Company will pay to, or reimburse,
LSB for its proportionate share of such usage.

     The Services Agreement provides that LSB will permit employees of the
Company and its subsidiaries to continue to participate in the benefit plans and
programs sponsored by LSB. The Company will pay to, or reimburse, LSB for the
costs associated with participation by the employees of the Company and LSB's
benefit plans and programs.

     Charges for such services aggregate $1,800,000 for each of the years ended
December 31, 1994, 1995 and 1996 and $1.4 million for each of the nine-month
periods ended September 30, 1996 and 1997. Management of the Company believes
these charges from LSB reasonably approximate additional general and
administrative costs which would have been incurred if the Company had been an
independent entity during such periods.

     The Company also leases the facilities of one of its Climate Control
manufacturing subsidiaries from an affiliate under an operating lease. See Note
9. Rental expense associated with the lease was $447,000 in each of the years
1994, 1995 and 1996.

     On November 21, 1997, LSB and the Company entered into a management
agreement (the "Management Agreement"), which provides that in future periods
LSB will provide to the Company, managerial oversight and

3.   TRANSACTIONS WITH RELATED PARTIES-CONTINUED

guidance concerning the broad policies, strategic decisions and operations of
the Company and the subsidiaries and the rendering of such further managerial
assistance as deemed reasonably necessary by LSB. Under the Management
Agreement, the Company is to pay LSB a fee for such services which will not
exceed $1.8 million annually. The fee will be paid quarterly based upon the
excess of actual earnings before interest, income taxes, depreciation and
amortization ("EBITDA") for the quarter minus $6,500,000, not to exceed
$450,000. If at the end of the calendar year, EBITDA is less than $26 million,
management fees paid to LSB during the year shall be refunded to the Company for
the first three quarters of the year, not to exceed $1,350,000. The maximum
management fee amount to be paid to LSB by the Company will be increased
annually commensurate with the percentage increase, if any, in the Consumer
Price Index during the preceding calendar year, beginning January 1, 1998.

     The Company has, at various times, maintained certain unsecured borrowings
from LSB and its subsidiaries and made loans to LSB which generally bear
interest. At December 31, 1996, net amounts due to LSB and its subsidiaries
aggregated $7.8 million. At September 30, 1997, the Company had loans to LSB of
approximately $22.9 million and borrowings from LSB and its affiliates of
approximately $19.3 million. The Company and LSB expect to repay substantially
all amounts owed to each other in 1997.

     Interest on loans and intercompany borrowings with LSB and its affiliates
generally approximate 7% per annum. Interest expense on net borrowings from LSB
and affiliates was approximately $378,000, $62,000 and $338,000 for the years
ended December 31, 1994, 1995 and 1996 and $120,000 and interest income of
$86,000 for the nine months ended September 30, 1996 and 1997, respectively. The
estimated fair value of the net amounts due to LSB and affiliates at December
31, 1995 and 1996 approximated their carrying value.

6.   LONG-TERM DEBT (CONTINUED)

____________________            
(A) In December 1994, LSB and certain of its subsidiaries (the ''Borrowing
    Group'') and a bank entered into a series of asset-based revolving credit
    facilities based upon defined eligible assets. The agreement provided for an
    initial term of three years. In October 1997, LSB and certain subsidiaries
    amended the agreement, revising certain financial covenants and extending
    the term to at least October 1998. In November 1997, the Company amended the
    agreement conditioned upon, among other things, completion of a senior note
    offering to raise at least $100 million. See Note 12.  The Amended Agreement
    provides for a $65 million revolving credit facility (the ''Revolving Credit
    Facility'') with four separate loan agreements (the ''Credit Facility
    Agreement''), one for the subsidiaries of the Company and three for LSB and
    its subsidiaries which are not subsidiaries of the Company. Under the
    Revolving Credit Facility, LSB and certain subsidiaries of LSB that are not
    subsidiaries of the Company have a right to borrow on a revolving basis, up
    to $24 million. Any amounts borrowed by LSB and its subsidiaries that are
    not subsidiaries of the Company will reduce the amount that the subsidiaries
    of the Company may borrow at any one time under the Revolving Credit
    Facility. Borrowings under the Revolving Credit Facility bear an annual rate
    of interest at a floating rate based on the lender's prime rate plus 1.5%
    per annum or, at the Company's option, on the lender's LIBOR rate plus
    3.875% per annum (which rates are subject to increase or reduction upon
    achieving specified availability and adjusted tangible net worth, as
    defined). The agreement will terminate on December 31, 2000, subject to
    automatic renewal for terms of 13 months each, unless terminated by either
    party. The Credit Facility Agreement also requires the payment of an annual
    facility fee equal to 0.5% of the unused Revolving Credit Facility. The
    Company may terminate the Revolving Credit Facility prior to maturity;
    however, should the Company do so, it would be required to pay a termination
    fee equal to 1% of the average daily balance of loans and letters of credit
    outstanding during the 180 day period immediately prior to termination.

    Each of the Credit Facility Agreements specify a number of events of default
    and requires the Company to maintain certain financial ratios (including
    adjusted tangible net worth and debt ratios), limits the amount of capital
    expenditures, and contains other covenants which restrict, among other
    things, (i) the incurrence of additional debt (other than as allowed under
    the loan agreements); (ii) the payment of dividends and other distributions;
    (iii) the making of certain investments; (iv) certain mergers, acquisitions
    and dispositions; (v) the issuance of secured guarantees; and (vi) the
    granting of certain liens.

    Events of default under the Revolving Credit Facility include, among other
    things, (i) the failure to make payments of principal, interest, and fees,
    when due; (ii) the failure to perform covenants contained therein; (iii) the
    occurrence of a change in control of LSB if any party is or becomes the
    beneficial owner of more than 50% of the total voting securities of LSB,
    except for Jack E. Golsen or members of his immediate family; (iv) default
    under any material agreement or instrument (other than an agreement or
    instrument evidencing the lending of money) which would have a material
    adverse effect on the Company and its subsidiaries which are borrowers under
    the Revolving Credit Facility, taken as a whole, and which is not cured
    within the grace period; (v) a default under any other agreement relating to
    borrowed money exceeding certain limits; and (vi) customary bankruptcy or
    insolvency defaults.

    The Revolving Credit Facility is secured by the accounts receivable,
    inventory, proprietary rights, general intangibles, books and records, and
    proceeds thereof of the Company.

(B) This agreement between a subsidiary of the Company and two institutional
    lenders provided for two series of term loans and a revolving credit
    facility. The balance outstanding at December 31, 1996 was paid in February
    1997. See Note (D).

6.   LONG-TERM DEBT (CONTINUED)

(C) This agreement, as amended, between a subsidiary of the Company and an
    institutional lender provided for a loan in the aggregate amount of $16.5
    million, the proceeds of which were used in the construction of a nitric
    acid plant, requiring 84 equal monthly payments of principal plus interest,
    with interest at a fixed rate of 8.86%. This agreement is secured by the
    plant, equipment and machinery, and proprietary rights associated with the
    plant which has an approximate carrying value of $30.4 million at December
    31, 1996.

    In November 1997, the Company amended this agreement, conditioned upon,
    among other things, completion of a senior note offering to raise at least
    $100 million. See Note 12. The amended agreement restates the financial and
    restrictive covenants to be applicable to the Company. This agreement, as
    amended, contains covenants (i) requiring maintenance of an escalating
    tangible net worth, (ii) restricting distributions and dividends from a
    subsidiary of the Company to the Company to 50% of the subsidiary's annual
    net income, as defined, (iii) restricting a change of control of the Company
    and (iv) requiring maintenance of a debt to tangible net worth ratio.

(D) On February 13, 1997, certain subsidiaries of the Company entered into a $50
    million financing arrangement with John Hancock Mutual Life Insurance
    Company (the ''Note Agreement''). The Note Agreement consists of $25.0
    million of fixed rate notes bearing interest at 10.57% per annum and $25.0
    million of floating rate notes bearing interest at LIBOR plus 4.2%
    (initially 9.76%). Repayment of the notes is due in quarterly installments
    of principal of $833,332 plus interest commencing on July 1, 1997 through
    maturity in April 2004. Approximately $19.3 million of the proceeds from the
    Note Agreement were used to retire the principal balances outstanding on the
    term and revolving credit facility discussed in (B) above and the secured
    loan due in monthly installments through 2003. The remaining proceeds of the
    Note Agreement (approximately $30.7 million) were used to pay down the
    revolving credit facility described in (A) and the outstanding balance due
    to LSB and affiliates. In connection with the financing, $9.5 million of
    debt previously due within one year has been classified as due after one
    year reflecting the payment terms of the Note Agreement. See Note 12.

    The notes are secured by real and personal property of the subsidiaries. The
    Note Agreement contains several financial covenants related to the borrowing
    subsidiaries. These financial covenants, as defined, include the maintenance
    of a debt to capitalization ratio, combined net worth, combined working
    capital, current ratio and fixed charge coverage ratio. The Note Agreement
    also restricts payments that can be made by the borrowing subsidiaries to
    LSB or its subsidiaries and restricts the Company's ability to prepay the
    floating rate notes prior to February 1999.

Maturities of long-term debt, after consideration of the Note Agreement and
Revolving Credit Facility discussed in (A) and (D) above, for each of the five
years after December 31, 1996 are: (in thousands) 1997--$10,825; 1998--$7,919;
1999--$8,016; 2000--$26,236; 2001--$7,068 and thereafter--$22,524.

8.   STOCKHOLDERS' EQUITY

 Stock Options

     Certain employees of the Company, including members of management of
LSB devoting time to the Company, participate in the incentive stock option
plans of LSB (the ''Stock Option Plans''). As a result thereof, the Company has
elected to follow Accounting Principles Board Opinion No. 25, ''Accounting for
Stock Issued to Employees'' (''APB 25'') and related interpretations in
accounting for such employee stock options because, as discussed below, the
alternative fair value accounting provided for under FASB Statement No. 123,
''Accounting for Stock-Based Compensation,'' requires use of option valuation
models that were not developed for use in valuing employee stock options. Under
APB 25, because the exercise price of the employee stock options equals the
market price of the underlying LSB stock on the date of grant, no compensation
expense is recognized.

     Pro forma information regarding net income is required by Statement 123,
which also requires that the information be determined as if the Company has
accounted for such employee stock options granted subsequent to December 31,
1994 under the fair value method of that Statement. The fair value for these
options was estimated by LSB at the date of grant using a Black-Scholes option
pricing model with the following weighted average assumptions for 1996 and 1995,
respectively: risk-free interest rates of 6.0% and 6.2%; a dividend yield of
1.36% and 1.02%; volatility factors of the expected market price of the
Company's common stock of .42 and .42; and a weighted average expected life of
the option of 6.2 and 8.0 years.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of such employee stock options.

     Because Statement 123 is applicable only to options granted subsequent to
December 31, 1994, its pro forma effect will not be fully reflected until 1997.

     At December 31, 1996, there are 549,050 options outstanding under the
Stock Option Plans related to employees of the Company and members of LSB
management devoting time to the Company. These options become exercisable 20%
after one year from date of grant, 40% after two years, 70% after three years,
100% after four years and lapse at the end of ten years. The exercise price of
options to be granted under this plan is equal to the fair market value of LSB's
common stock at the date of grant.

     Activity in the Stock Option Plans related to Company employees and
members of LSB management devoting time to the Company during each of the three
years in the period ended December 31, 1996 is as follows:

     Rent expense under all operating lease agreements, including month-to-month
leases, was $2,798,000 in 1994, $2,692,000 in 1995 and $3,687,000 in 1996.
Renewal options are available under certain of the lease agreements for various
periods at approximately the existing annual rental amounts.

     The Company leases certain precious metals for use in the Company's
manufacturing process under 90 day agreements. The agreement at December 31,
1996 required, among other things, rentals generally based on 7.85% of the
leased metals' market values. The agreement at September 30, 1997 requires
rentals generally based on 22% of the leased metals' market values from October
1997 through December 1997, contract expiration. The agreements also require the
Company to purchase 900 ounces of platinum at $450 per ounce if the spot price
for platinum is $450 per ounce or lower at the end of the lease term.

     In July 1995, the Company entered into a product supply agreement with a
third party whereby the Company is required to make monthly facility fee and
other payments which aggregate $71,965. In return for this payment, the Company
is entitled to certain quantities of compressed oxygen produced by the third
party. Except in circumstances as defined by the agreement, the monthly payment
is payable regardless of the quantity of compressed oxygen used by the Company.
The term of this agreement, which has been included in the above minimum
operating lease commitments, is for a term of 15 years; however, after the
agreement has been in effect for 60 months, the Company can terminate the
agreement without cause at a cost of approximately $4.5 million. Based on the
Company's estimate of compressed oxygen demands of the plant, the cost of the
oxygen under this agreement is not expected to exceed market prices.

     In June 1997, two wholly owned subsidiaries of the Company, El Dorado
Chemical Company (''EDC''), and El Dorado Nitrogen Company (''EDNC''), entered
into a series of agreements with Bayer Corporation (''Bayer'') (collectively,
the ''Bayer Agreement''). Under the Bayer Agreement, EDNC will act as an agent
to construct, and upon completion of construction, will operate a nitric acid
plant (the ''EDNC Baytown Plant'') at Bayer's Baytown, Texas chemical facility.
EDC has guaranteed the performance of EDNC's obligations under the Bayer
Agreement. Under the terms of the Bayer Agreement, EDNC is to lease the EDNC
Baytown Plant pursuant to an operating lease from an unrelated third party with
an initial lease term of ten years from the date on which the EDNC Baytown Plant
becomes

the EDNC Baytown Plant becomes operational, the Bayer Agreement may be renewed
for up to six renewal terms of five years each; however, prior to each renewal
period, either party to the Bayer Agreement may opt against renewal. It is
anticipated that construction of the EDNC Baytown Plant will cost approximately
$60 million and will be completed by late 1998. Construction financing of the
EDNC Baytown Plant is to be provided by an unaffiliated lender. Neither the
Company nor EDC has guaranteed any of the lending obligations for the EDNC
Baytown Plant.

  Legal Matters

     Following is a summary of certain legal actions involving the Company:

     A. The Company submitted to the State of Arkansas a "Groundwater
Monitoring Work Plan" which was approved by the State of Arkansas. Pursuant to
the Groundwater Monitoring Work Plan, the Company has performed phase I and II
groundwater investigations, and submitted a risk assessment report to the State
of Arkansas. The risk assessment report is currently being reviewed by the State
of Arkansas.

     On February 12, 1996, the Company entered into a Consent Administrative
Agreement ("Administrative Agreement") with the state of Arkansas to resolve
certain compliance issues associated with nitric acid concentrators. Pursuant to
the Administrative Agreement, the Company installed additional pollution control
equipment to address the compliance issues. The Company was assessed $50,000 in
civil penalties associated with the Administrative Agreement. In the summer of
1996 and then on January 28, 1997, the Company executed amendments to the
Administrative Agreement ("Amended Agreements"). The Amended Agreements
imposed a $150,000 civil penalty, which penalty has been paid. Since the 1997
amendment, the Chemical business has been assessed stipulated penalties of
approximately $55,000 by the ADPC&E for violations of certain provisions of the
1997 Amendment. The Chemical Business believes that the El Dorado Plant has made
progress in controlling certain off-site emissions; however, such off-site
emissions have occurred and continue to occur from time to time, which could
result in the assessment of additional penalties against the Chemical Business
by the ADPC&E for violation of the 1997 Amendment.

     B. In 1996, a lawsuit was filed against the Company's Chemical Business by
a group of residents of El Dorado, Arkansas, asserting a citizens' suit against
the Chemical Business as a result of certain alleged violations of the Clean Air
Act, the Clean Water Act, the Chemical Business' air and water permits and
certain other environmental laws, rules and regulations. The citizens' suit
requests the court to order the Chemical Business to cure such alleged
violations, if any, plus penalties as provided under the applicable statutes.
The Company's Chemical Business will assert all defenses available to it and
will vigorously defend itself.

     In July 1996, several of the same individuals who are plaintiffs in the
citizens' suit referenced above filed a toxic tort lawsuit against the Company's
Chemical Business alleging that they suffered certain injuries and damages as a
result of alleged releases of toxic substances from the Chemical Business' El
Dorado, Arkansas manufacturing facility. In October 1996, another toxic tort
lawsuit was filed against the Company's Chemical Business. This subsequent
action asserts similar damage theories as the previously discussed lawsuit,
except this action attempts to have a class certified to represent substantially
all allegedly affected persons. The plaintiffs are suing for an unspecified
amount of actual and punitive damages.

     The Company's insurance carriers have been notified of these matters. The
Company and the Chemical Business maintain an Environmental Impairment Insurance
Policy ("EIL Insurance") that provides coverage to the Company and the
Chemical Business for certain discharges, dispersals, releases, or escapes of
certain contaminants and pollutants into or upon land, the atmosphere or any
water course or body of water from the Site, which has caused bodily injury,
property damage or contamination to others or to other property not on the Site.
The EIL Insurance provides limits of liability for each loss up to $10.0 million
and a similar $10.0 million limit for all losses due to bodily injury or
property

damage, except $5.0 million for all remediation expenses, with the maximum limit
of liability for all claims under the EIL Insurance not to exceed $10.0 million
for each loss or remediation expense and $10.0 million for all losses and
remediation expenses. The EIL Insurance also provides a retention of the first
$500,000 per loss or remediation expense that is to be paid by the Company. The
Company's Chemical Business has spent an amount in excess of $500,000 in legal,
expert and other costs in connection with the toxic tort and citizen lawsuits
described in paragraph C, which the Company expensed and has made a claim
against its EIL Insurance for reimbursement of the legal, expert and other costs
paid by the Chemical Business in excess of $500,000 and to pay such legal,
expert and other costs on an on-going basis. In September 1997, the Company and
the EIL Insurance Carrier agreed that the EIL Insurance Carrier will reimburse
the Chemical Business for certain expenses in excess of retention, and pay such
future fees and expenses, subject to a reservation of rights relating to the
citizens' suit.  See Note 12.

     C. A civil cause of action has been filed against the Company's Chemical
Business and five (5) other unrelated commercial explosives manufacturers
alleging that the defendants allegedly violated certain federal and state
antitrust laws in connection with alleged price fixing of certain explosive
products. The plaintiffs are suing for an unspecified amount of damages, which,
pursuant to statute, plaintiffs are requesting be trebled, together with costs.
Based on the information presently available to the Company, the Company does
not believe that the Chemical Business conspired with any party, including but
not limited to, the five (5) other defendants, to fix prices in connection with
the sale of commercial explosives. Discovery has only recently commenced in this
matter. The Chemical Business intends to vigorously defend itself in this
matter.

     The Company's Chemical Business has been added as a defendant in a separate
lawsuit pending in Missouri. This lawsuit alleges a national conspiracy, as well
as a regional conspiracy, directed against explosive customers in Missouri and
seeks unspecified damages. The Company's Chemical Business has been included in
this lawsuit because it sold products to customers in Missouri during a time in
which other defendants have admitted to participating in an antitrust
conspiracy, and because it has been sued in the preceding described lawsuit.
Based on the information presently available to the Company, the Company does
not believe that the Chemical Business conspired with any party, to fix prices
in connection with the sale of commercial explosives. The Chemical Business
intends to vigorously defend itself in this matter.

     For several years, certain members of the explosives industry have been the
focus of a grand jury investigation being supervised by the U.S. Department of
Justice ("DOJ") in connection with criminal antitrust allegations involving
price fixing. Certain explosives companies, other than the Company, including
all the Company's major competitors, and individuals employed by certain of
those competitors, were indicted and have pled guilty to antitrust violations.
The guilty pleas have resulted in nearly $40 million in criminal fines. In
connection with the grand jury investigation, the Company's Chemical Business
received and has complied with two document subpoenas, certain of the Company's
Chemical Business' employees have been interviewed by the DOJ under grants of
immunity from prosecution, and certain of the Company's Chemical Business
employees have testified under subpoena before the grand jury under grants of
immunity in connection with the investigation. The Company believes that it has
cooperated fully with the government's investigation. Recently, the Company has
been informed by an official of the DOJ that it is not currently a target of the
above investigation or of any grand jury investigating criminal antitrust
activity in the explosives or ammonium nitrate industries.

          During the third quarter of 1997, a subsidiary of the Company was
served with a lawsuit in which approximately 27 plaintiffs have sued
approximately 13 defendants, including a subsidiary of the Company alleging
personal injury and property damage for undifferentiated compensatory and
punitive damages of approximately $7,000,000. Specifically, the plaintiffs
assert blast damage claims, nuisance (road dust from coal trucks) and personal
injury claims

(exposure to toxic materials in blasting materials) on behalf of residents
living near the Heartland Coal Company ("Heartland") strip mine in Lincoln
County, West Virginia.  Heartland employed the subsidiary to provide blasting
materials and personnel to load and shoot holes drilled by employees of
Heartland.  Down hole blasting services were provided by the subsidiary at
Heartland's premises from approximately August 1991, until approximately August
1994. Subsequent to August 1994, the subsidiary supplied blasting materials to
the reclamation contractor at Heartland's mine. In connection with the
subsidiary's activities at Heartland, the subsidiary has entered into a
contractual indemnity to Heartland to indemnify Heartland under certain
conditions for acts or actions taken by the subsidiary for which the subsidiary
failed to take, and Heartland is alleging that the subsidiary is liable
thereunder for Heartland's defense costs and any losses to or damages sustained
by, the plaintiffs in this lawsuit. Discovery has only recently begun in this
matter, and the Company intends to vigorously defend itself in this matter.

     The Company including its subsidiaries, is a party to various other claims,
legal actions, and complaints arising in the ordinary course of business. In the
opinion of management after consultation with counsel, all claims, legal actions
(including those described above) and complaints are not presently probable of
material loss, are adequately covered by insurance, or if not so covered, are
without merit or are of such kind, or involve such amounts that unfavorable
disposition would not have a material effect on the financial position of the
Company, but could have a material impact to the net income (loss) of a
particular quarter or year, if resolved unfavorably.

     LSB and, thus, the Company has retained certain risks associated with its
operations, choosing to self-insure up to various specified amounts under its
automobile, workers' compensation, health and general liability programs. LSB
reviews such programs on at least an annual basis to balance the cost/benefit
between its coverage and retained exposure. See the Services Agreement, Note 3.

     The Company purchases substantial quantities of anhydrous ammonia for use
in manufacturing its products. The Company has contracts with two suppliers of
ammonia. One contract requires the Company to purchase not less than 75,000 tons
nor more than 140,000 tons of anhydrous ammonia each contract year and is for a
term expiring in December 1998. The other requires the Company to take or pay
for an average of 10,000 tons of anhydrous ammonia per month and expires April
2000. These contracts are at floating prices. The pricing volatility of such raw
material directly affects the operating profitability of the Company. The
Company also enters into agreements with suppliers of raw materials which
require the Company to provide finished goods in exchange therefore. At December
31, 1996, the Company had received quantities of anhydrous ammonia in exchange
for which the Company has a commitment to provide 72,184 tons of ammonium
nitrate and 5,130 tons of nitric acid. The Company believes these agreements are
generally favorable to the Company and can meet the delivery commitments in the
ordinary course of business. At September 30, 1997, the Company has a standby
letter of credit outstanding related to its Chemical Business of $3.5 million.

     The Company operates a concentrated nitric acid plant which has a stated
production capacity of 285 tons per day. The Company has incurred significant
delays and costs in attempting to achieve the plant's stated capacity. The
Company anticipates maintaining an economically feasible rate of production. If
such rate of production is not maintained, the Company may sustain significant
future operating losses and possible impairment related thereto.

     The following discussion of fair values is not indicative of the overall
fair value of the Company's balance sheet since the provisions of the SFAS No.

10.  FAIR VALUE OF FINANCIAL INSTRUMENTS-CONTINUED

     The following methods and assumptions were used by the Company in
estimating its fair value of financial instruments:

     Fair values for fixed rate borrowings are estimated using a discounted cash
     flow analysis that applies interest rates currently being offered on
     borrowings of similar amounts and terms to those currently outstanding.
     Carrying values for variable rate borrowings approximate their fair value.
     As of December 31, 1995 and 1996 and September 30, 1997, carrying values of
     variable rate and fixed-rate long-term debt which aggregated $79.0 million,
     $82.6 million and $106.9 million, respectively, approximated their
     estimated fair value.

     As of December 31, 1996, the carrying values of cash and cash equivalents,
accounts receivable, accounts payable, and accrued liabilities approximated
their estimated fair value.

11.  SEGMENT INFORMATION

     The Company and its subsidiaries operate principally in two industries.

  Chemical

     This segment manufactures and sells chemical products for mining,
agricultural, electronic, paper and other industries. Production from the
Company's primary manufacturing facility in El Dorado, Arkansas, for the year
ended December 31, 1996 comprises approximately 72% of the chemical segment's
sales. Sales to customers of this segment primarily include coal mining
companies in Kentucky, West Virginia, Illinois and Indiana and farmers in Texas
and Arkansas.

     The Chemical Business is subject to various federal, state and local
environmental regulations. Although the Company has designed policies and
procedures to help reduce or minimize the likelihood of significant chemical
accidents and/or environmental contamination, there can be no assurances that
the Company will not sustain a significant future operating loss related
thereto.

     In May 1997, the Chemical Business completed constructing a concentrated
nitric acid plant (carrying value of $30.4 million at December 31, 1996; $30.6
million at September 30, 1997) which has a stated production capacity of 285
tons per day. The Company has incurred significant delays and costs in
attempting to achieve the plant's stated capacity. The Company anticipates
maintaining an economically feasible rate of production. If such rate of
production is not maintained, the Company may sustain significant future
operating losses and possible impairment related thereto.

     Further, the Company purchases substantial quantities of anhydrous ammonia
for use in manufacturing its products. The pricing volatility of such raw
material directly affects the operating profitability of the chemical segment.

  Climate Control

     This business segment manufactures and sells, primarily from its various
facilities in Oklahoma City, a variety of hydronic fan coil, water source heat
pump products as well as other HVAC products for use in commercial and
residential air conditioning and heating systems. The Company's various
facilities in Oklahoma City comprise substantially all of the environment
control operations. Sales to customers of this segment primarily include
original equipment manufacturers, contractors and independent sales
representatives located throughout the world, are generally secured by a
mechanic's lien, except for sales to original equipment manufacturers.

     Credit, which is generally unsecured, is extended to customers based on an
evaluation of the customers' financial condition and other factors. Credit
losses are provided for in the financial statements based on historical
experience and periodic assessment of outstanding accounts receivable,
particularly those accounts which are past due. The Company's periodic
assessment of accounts and credit loss provisions are based on the Company's
best estimate of amounts which are not recoverable. Concentrations of credit
risk with respect to trade receivables are limited due to the large number of
customers comprising the Company's customer bases, and their dispersion across
many different industries and geographic areas.

     Information about the Company's operations in different industry segments
is detailed below.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 (INFORMATION FOR THE NINE-MONTH PERIODS ENDED SEPTEMBER 30, 1996 AND 1997 IS
                                  UNAUDITED)

12.  SUBSEQUENT EVENTS (UNAUDITED)
 
     On November 26, 1997, the Company completed the sale of $105 million
principal amount of 10 3/4% Senior Notes due 2007 (the "Notes"). The proceeds of
the Notes were used to (a) fully repay the principal and prepayment fees of the
John Hancock Mutual Life Insurance Company loan described in Note 6(D), (b)
reduce amounts outstanding under various revolving credit facilities with
respect to the Chemical Business and the Climate Control Business; and (c) fund
a loan to LSB, the Company's parent, of $10 million. The Notes bear interest at
an annual rate of 10 3/4% payable semiannually in arrears on June 1 and December
1 of each year. The Notes are senior unsecured obligations of the Company and
rank pari passu in right of payment to all existing senior unsecured
indebtedness of the Company. The Notes are effectively subordinated to all
existing and future senior secured indebtedness of the Company and its
subsidiaries. As of November 30, 1997, after application of the net proceeds
from the sale of the Notes, the Company had $3.1 million of outstanding
borrowings under its revolving credit facilities and $20.2 million of other
secured indebtedness, all of which is effectively senior to the Notes.

     The Notes were issued pursuant to an Indenture, which contains certain
covenants that, among other things, limit the ability of the Company and its
subsidiaries to: (i) incur additional indebtedness; (ii) incur certain liens;
(iii) engage in certain transactions with affiliates; (iv) make certain
restricted payments; (v) agree to payment restrictions affecting subsidiaries;
(vi) engage in unrelated lines of business; or (vii) engage in mergers,
consolidations or the transfer of all or substantially all of the assets of the
Company to another person. In addition, in the event of certain Asset Sales (as
defined), the Company will be required to use the proceeds to reinvest in the
Company's business, to repay certain debt or to offer to purchase Notes at 100%
of the principal amount thereof, plus accrued and unpaid interest, if any,
thereon, plus Liquidated Damages (as defined), if any, to the date of purchase.

     Except as described below, the Notes are not redeemable at the Company's
option prior to December 1, 2002. After December 1, 2002, the Notes will be
subject to redemption at the option of the Company, in whole or in part, at the
redemption prices set forth in the Indenture, plus accrued and unpaid interest
thereon, plus Liquidated Damages, if any, to the applicable redemption date. In
addition, until December 1, 2000, up to $35 million in aggregate principal
amount of Notes are redeemable, at the option of the Company, at a price of
110.75% of the principal amount of the Notes, together with accrued and unpaid
interest, if any, thereon, plus Liquidated Damages, if any, to the date of the
redemption, with the net cash proceeds of a Public Equity Offering (as defined);
provided, however, that at least $65 million in aggregate principal amount of
the Notes remain outstanding following such redemption.

     In the event of a Change of Control of LSB or the Company, holders of the
Notes will have the right to require the Company to repurchase the Notes, in
whole or in part, at a redemption price of 101% of the principal amount thereof,
plus accrued and unpaid interest, if any, thereon, plus Liquidated Damages, if
any, to the date of repurchase.

     The Company is a holding company with no assets or operations other than
its investments in its subsidiaries, and each of its subsidiaries is wholly
owned, directly or indirectly. ClimaChem's payment obligations under the Notes
are fully, unconditionally and joint and severally guaranteed by all of the
existing subsidiaries of the Company, except for El Dorado Nitrogen Company
("EDNC"). The assets, equity, and earnings of EDNC are inconsequential for all
periods presented and management of the Company does not believe separate
financial information of the guaranteeing subsidiaries is material to the
understanding of investors of the Notes.

     During January 1998, the Company's Chemical Business agreed in principal to
settle the toxic tort lawsuit filed against the Company in October 1996, which
settlement, if completed, will be funded from the Company's EIL Insurance. The
settlement is subject to court approval, execution of definitive agreements, and
confirmation from the Company's EIL Insurance carrier that it will pay the full
amount of such settlement.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          The Company and each of the Guarantors (except as set forth below) are
incorporated under the laws of the State of Oklahoma. Section 1031 of the
Oklahoma General Corporation Act authorizes indemnification of the Company's
directors and officers in a variety of circumstances, which may include
liabilities under the Securities Act of 1933, as amended (the "Securities Act").

          Climate Master, Inc. ("CM") is incorporated under the laws of the
State of Delaware. Section 145 of the Delaware General Corporation Law (the
"Delaware Law") authorizes indemnification of CM's directors and officers under
a variety of circumstances which may include liabilities under the Securities
Act.

          The general effect of the foregoing is to provide that each of the
domestic Registrants will indemnify its directors and officers against all
liabilities and expenses actually and reasonably incurred in connection with the
defense or settlement of any judicial or administrative proceedings in which
they have become involved by reason of their status as corporate directors or
officers, if they acted in good faith and in the reasonable belief that their
conduct was neither unlawful (in the case of criminal proceedings) nor
inconsistent with the best interests of a particular Registrant. With respect to
legal proceedings by, or in the right of, a Registrant, in which a director or
officer is adjudged liable for improper performance of his duty to the
Registrant or another enterprise which such person served in a similar capacity
at the request of the Registrant, indemnification is limited by such provisions
to that amount which is permitted by the court.

          The Environmental Group International Limited ("TEGI") is incorporated
under the laws of the United Kingdom. Article 13(a) of TEGI's Articles of
Association provides that every director or other officer of TEGI shall be
indemnified out of the assets of TEGI against all losses or liabilities which he
may sustain or incur in or about the execution of the duties of his office or
otherwise in relation thereto, including any liability incurred by him in
defending any proceedings, whether civil or criminal, or in connection with any
application under certain provisions of the Companies Act of 1985 in which
relief is granted to him by the court, and no director or other officer shall be
liable for any loss, damage or misfortune which may happen to or be incurred by
TEGI in the execution of the duties of his office or in relation thereto;
provided that Article 13 shall only have effect insofar as its provisions are
not avoided by certain provisions of the Companies Act of 1985.

          Climate Mate Inc. ("CMI") is incorporated under the laws of the
Province of Ontario, Canada.  Section 2.08 of CM's Bylaws provides that, except
as provided in the Business Corporations Act of 1982--Ontario, every director
and officer of CMI, every former director and officer of CMI, and every person
who acts or acted at CMI's request as a director or officer of another
corporation of which CMI is, or was, a shareholder or creditor, and his heirs or
legal representatives, shall at all times be indemnified and saved harmless by
CMI from and against all costs, charges and expenses, including an amount paid
to settle any action or satisfy a judgment reasonably incurred by him in respect
of any civil, criminal or administrative action or proceeding to which he is
made a party by reason of, or having been a director or officer of, CMI or such
other corporation if (a) he acted honestly and in good faith with a view to the
best interests of CMI, and (b) in the case of a criminal or administrative
action or proceeding that is enforced by monetary penalty, he had reasonable
grounds for believing that his conduct was lawful.

          Total Energy Systems Limited ("TES") and T.E.S. Mining Services Pty.
Ltd. ("TES Mining") are registered under the law of Queensland, Australia.
Article 26.1 of the TES Articles of Association provide that every officer,
auditor or agent of TES is indemnified by the Company for all liabilities
incurred by him in his capacity as, or by reason of his holding the position of,
officer, auditor or agent, as the case may be, to the extent permitted by law,
and such indemnity extends to any liability incurred by him in defending any
proceedings, whether civil or criminal, in which judgment is given in his favor
or in which he is acquitted or in connection with any application in relation to
any such proceedings

                                     II-1
<PAGE>
 
in which relief is granted to him by the court under law.  Article 38(a) of the
T.E.S. Mining Articles of Association provides that no director or manager,
secretary or other officer of TES Mining acting in good faith and within the
scope of his duties or what he believes to be the scope of his duties shall be
liable for any loss, damage or misfortune which may occur whether the same be
occasioned by any mistake, error, oversight or omission on his part or not.

          Total Energy Systems (NZ) Limited ("TES (NZ") is incorporated under
the laws of New Zealand. Article 11.1 of the Constitution of TES (NZ) provides
that the board of TES (NZ) may cause TES (NZ) to indemnify a director and former
director and former employee or employee of TES (NZ) or a related company for
costs incurred by him or her in any proceeding that relates to (a) liability for
any act or omission in his or her capacity as a director or employee and (b) in
which judgment is given in his or her favor or in which he or she is acquitted
or which is discontinued. Article 11.1 provides further that the board may cause
TES (NZ) to indemnify a director or an employee or former director or former
employee of TES (NZ) or a related company in respect of (a) liability to any
person other than TES (NZ) or a related company for any act or omission in his
or her capacity as a director or employee; or (b) costs incurred by the director
or employee in defending or settling any claim or proceeding relating to any
liability under the foregoing sentence, provided that the liability is not
criminal or (in the case of a director) in respect of a breach of the duty to
act in good faith and in the best interests of TES (NZ) or (in the case of an
employee) in respect of a breach of any fiduciary duty owed to TES (NZ) or a
related company.

          LSB, the Company or a Guarantor Subsidiary maintains officers' and
directors' liability insurance which insures against liabilities that officers
and directors of each Registrant may incur in such capacities.

                                 UNDERTAKINGS

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the indemnification provisions described herein, or
otherwise, the Registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer or controlling person of the Company in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business date of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     The undersigned registrants hereby undertake to supply by means of a post-
effective amendment all information concerning a transaction and the company
being acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.

Dear Sirs:

          ClimaChem, Inc., an Oklahoma corporation (the "Company"), proposes,
upon the terms and conditions set forth herein, to issue and sell to you, as the

pursuant to the provisions of an Indenture, to be dated as of November 26, 1997
(the "Indenture"), between the Company and Bank One, NA, as Trustee (the
"Trustee").  The Notes are to be unconditionally guaranteed (the "Guarantees")

include the Guarantees.

          The Company wishes to confirm as follows its agreement with the

          1.   Preliminary Offering Memorandum and Offering Memorandum.  The
Notes will be offered and sold to the Initial Purchaser without registration
under the Securities Act of 1933, as amended (the "Act"), in reliance on an

preliminary offering memorandum, dated October 30, 1997 (the "Preliminary
Offering Memorandum"), and an offering memorandum, dated November 21, 1997 (the
"Offering Memorandum"), setting forth information regarding the Company and the
Notes.  Any references herein to the Preliminary Offering Memorandum shall be
deemed to include all amendments and supplements thereto.  Any references herein
to the Offering Memorandum shall refer to the Offering Memorandum in the form
first furnished to the Initial Purchaser for use in connection with the offering
of the Notes.  The Company hereby confirms that it has authorized the use of the
Preliminary Offering Memorandum and the Offering Memorandum in connection with
the offering and resale of the Notes by the Initial Purchaser.
<PAGE>
 
          The Initial Purchaser has advised the Company that it proposes to make
offers and sales (the "Exempt Resales") of the Notes purchased by it hereunder
only on the terms and in the manner set forth in the Offering Memorandum and
Section 2 hereof, as soon as it deems advisable after this Agreement has been
executed and delivered, (i) to persons in the United States whom the Initial
Purchaser reasonably believe to be qualified institutional buyers ("Qualified
Institutional Buyers") as defined in Rule 144A under the Act, as such rule may
be amended from time to time ("Rule 144A"),  in transactions under Rule 144A,
(ii) to a limited number of other institutional "accredited investors" (as
defined in Rule 501 (a) (1), (2), (3) and (7) under Regulation D of the Act)
("Accredited Investors") in private sales exempt from registration under the Act
and (iii) to certain persons in offshore transactions in reliance on Regulation
S under the Act ("Regulation S") (such persons specified in clauses (i), (ii)
and (iii) being referred to herein as the "Eligible Purchasers").

          It is understood and acknowledged that upon original issuance thereof,
and until such time as the same is no longer required under the applicable
requirements of the Act, the Notes shall bear a legend substantially to the
effect set forth below:

          "THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY MAY NOT BE OFFERED
          OR SOLD TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY PERSON EXCEPT AS SET
          FORTH IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE
          HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER"
          (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN
          "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(a)(1), (2), (3) or (7)

          SECURITIES ACT, (C) TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT,
          PRIOR TO SUCH TRANSFER, FURNISHES TO THE TRUSTEE A WRITTEN
          CERTIFICATION CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS
          RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS NOTE (THE FORM OF

          CASE OF CLAUSES (C), (D), (F) AND (G) ABOVE, UPON AN OPINION OF
          COUNSEL REASONABLY ACCEPTABLE TO THE ISSUER IF THE ISSUER SO
          REQUESTS), SUBJECT IN EACH OF THE FOREGOING CASES TO ANY REQUIREMENT
          OF LAW THAT THE DISPOSITION OF ITS PROPERTY OR THE REQUIREMENT OF LAW
          THAT THE DISPOSITION OF ITS PROPERTY OR THE PROPERTY OF SUCH ACCOUNT
          BE AT ALL TIMES WITHIN ITS CONTROL AND TO COMPLIANCE WITH APPLICABLE
          STATE SECURITIES LAWS AND (3) AGREES THAT IT WILL DELIVER TO EACH
          PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE
          EFFECT OF THIS LEGEND. IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL
          ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH
          TO THE TRUSTEE AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR
          OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM
          THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN
          A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
          SECURITIES ACT. THE FOREGOING RESTRICTIONS ON RESALE WILL NOT APPLY
          SUBSEQUENT TO THE RESALE RESTRICTION TERMINATION DATE."

          It is also understood and acknowledged that holders (including
subsequent transferees) of the Notes will have the registration rights set forth

          2.   Agreements to Sell, Purchase and Resell.  (a) The Company hereby
agrees, subject to all the terms and

                                       3
<PAGE>
 
conditions set forth herein, to issue and sell to the Initial Purchaser and,
upon the basis of the representations, warranties and agreements of the Company
herein contained and subject to all the terms and conditions set forth herein,
the Initial Purchaser agrees to purchase from the Company, at a purchase price
of 97% of the principal amount thereof, the Notes.

          (b)  The Initial Purchaser has advised the Company that it proposes to
offer the Notes for sale upon the terms and conditions set forth in this
Agreement and in the Offering Memorandum.  The Initial Purchaser hereby
represents and warrants to, and agrees with, the Company that it (i) is a
Qualified Institutional Buyer, with such knowledge and experience in financial
and business matters as are necessary in order to evaluate the merits and risks
in an investment in the Notes and is purchasing the Notes pursuant to a private
sale exempt from registration under the Act, (ii) has not and will not solicit
offers for, or offer or sell, the Notes by means of any form of general
solicitation or general advertising or in any manner involving a public offering
within the meaning of Section 4(2) of the Act provided, however, that such
                                              --------  -------           
limitation shall not preclude the Initial Purchaser from placing any tombstone
announcement with respect to the resale by it of the Notes, (iii) will solicit
offers for the Notes only from, and will offer, sell or deliver the Notes as
part of its initial offering, only to (A) persons in the United States whom it
reasonably believes to be Qualified Institutional Buyers, or if any such person
is buying for one or more institutional accounts for which such person is acting
as fiduciary or agent, only when such person has represented to such Initial
Purchaser that each such account is a Qualified Institutional Buyer, to whom
notice has been given that such sale or delivery is being made in reliance on
Rule 144A, in each case, in transactions under Rule 144A or (B) to a limited
number of Accredited Investors that make the representations to and agreements
with the Company specified in Annex A to the Offering Memorandum, in private
sales exempt from registration under the Act or (C) to certain persons in
offshore transactions in reliance in Regulation S and (iv) will, during its
initial distribution of the Notes, unless prohibited by applicable law, furnish
to each person to whom it sells any Notes a copy of the Offering Memorandum.

          The Initial Purchaser represents and agrees that it has offered and
sold Notes and will offer and sell Notes (i) as part of its distribution at any
time and (ii) otherwise until forty days after the later of the date upon which
the offering of the Securities commences and the Closing Date, only in
accordance with Rule 903 of Regulation S or in 

                                       4
<PAGE>
 
accordance with clauses (A) and (B) above. Accordingly, neither the Initial
Purchaser, its affiliates nor any persons acting on their behalf have engaged or
will engage in any directed selling efforts with respect to Notes, and the
Initial Purchaser, its affiliates and any person acting on their behalf have
complied and will comply with the offering restriction requirements of
Regulation S. The Initial Purchaser agrees that, at or prior to confirmation of
a sale of Notes (other than a sale of Notes pursuant to Rule 144A or to an
Accredited Investor), it will have sent to each distributor, dealer or person
receiving a selling concession, fee or other remuneration that purchases Notes
from it or through it during the restricted period a confirmation or notice to
substantially the following effect:

          "The Notes covered hereby have not been registered under the
          United States Securities Act of 1933 (the "Securities Act")
          and may not be offered or sold within the United States or
          to or for the account or benefit of U.S. persons (i) as part
          of their distribution at any time and (ii) otherwise until
          forty days after the later of the date upon which the
          offering of the Notes commenced and the date of closing,
          except in either case in accordance with Regulation S or
          another available exemption from the registration
          requirements of the Securities Act. Terms used above have
          the meaning given to them by Regulation S."

Terms used in the above paragraph have the meanings given to them by Regulation
S.

          The Initial Purchaser has advised the Company that it will offer the
Notes to Eligible Purchasers at a price and upon terms set forth in the Offering
Memorandum.  Such price and terms may be changed by the Initial Purchaser at any
time thereafter without notice.

          The Initial Purchaser understands that the Company and, for purposes
of the opinions to be delivered to the Initial Purchaser pursuant to Section 7
hereof, counsel to the Company and counsel to the Initial Purchaser, will rely
upon the accuracy and truth of the foregoing representations and agreements and
the Initial Purchaser hereby consents to such reliance.

                                       5
<PAGE>
 
          3.   Delivery of the Notes and Payment Therefor. Delivery to the
Initial Purchaser of and payment for the Notes shall be made at the office of
Skadden, Arps, Slate, Meagher & Flom LLP, 919 Third Avenue, New York, New York,

The place of closing for the Notes and the Closing Date may be varied by
agreement between the Initial Purchaser and the Company.

          The Notes which the Initial Purchaser may elect to purchase will be
delivered to the Initial Purchaser against payment of the purchase price
therefor in immediately available funds wired in accordance with the
instructions of the Company.  The Notes will be evidence by a single global
security in definitive form (the "Global Debenture")  and/or by additional
definitive securities, and  will be registered, in the case of the Global
Debenture, in the name of Cede & Co. as nominee of The Depository Trust Company
("DTC"), and in the other cases, in such names and in such denominations as the
Initial Purchaser shall request prior to 9:30 A.M., New York City time, on the
third business day preceding the Closing Date.  The Notes to be delivered to the
Initial Purchaser shall be made available to the Initial Purchaser in New York
City for inspection and packaging not later than 9:30 A.M., New York City time,
on the business day next preceding the Closing Date.

          4.   Agreements of the Company and the Guarantors. Each of the Company
and the Guarantors agrees with the Initial Purchaser as follows:

          (a)  The Company will advise the Initial Purchaser promptly and, if
requested by it, will confirm such advice in writing, within the period of time
referred to in the first sentence of subsection (e) below, of any material
change in the Company's condition (financial or other), business, prospects,
properties, net worth or results of operations, or of the happening of any event
which makes any material statement made in the Offering Memorandum (as then
amended or supplemented) untrue or which requires the making of any additions to
or changes in the Offering Memorandum (as then amended or supplemented) in order
to make the statements therein, in the light of the circumstances in which they
were made, not misleading, or of the necessity to amend or supplement the
Offering Memorandum (as then amended or supplemented) to comply with any law.

          (b)  The Company will furnish to the Initial Purchaser, without
charge, as of the date of the Offering Memorandum, such number of copies of the
Offering Memorandum 

                                       6
<PAGE>
 
as may then be amended or supplemented as it may reasonably request.

          (c)  The Company will not make any amendment or supplement to the
Preliminary Offering Memorandum or to the Offering Memorandum of which the
Initial Purchaser shall not previously have been advised or to which it shall
reasonably object after being so advised, and no such amendment or supplement
when it is made, shall contain an untrue statement of a material fact or will
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances in which
they were made, not misleading.

          (d)  Prior to the execution and delivery of this Agreement, the
Company has delivered or will deliver to the Initial Purchaser, without charge,
in such quantities as it shall have requested or may hereafter reasonably
request, copies of the Preliminary Offering Memorandum.  The Company consents to
the use, in accordance with the securities or Blue Sky laws of the jurisdictions
in which the Notes are offered by the Initial Purchaser and by dealers, prior to
the date of the Offering Memorandum, of each Preliminary Offering Memorandum so
furnished by the Company.  The Company consents to the use of the Offering
Memorandum (and of any amendment or supplement thereto) in accordance with the
securities or Blue Sky laws of the jurisdictions in which the Notes are offered
by the Initial Purchaser in connection with the offering and sale of the Notes.

          (e)  If, at any time prior to completion of the distribution of the
Notes by the Initial Purchaser to Eligible Purchasers, any material event shall

the Initial Purchaser sold Notes to that person without sending or giving at or
prior to the written confirmation of such sale, a copy of the Offering
Memorandum (as then amended or supplemented) if the 

                                       19
<PAGE>
 
Company has previously furnished sufficient copies thereof to the Initial
Purchaser on a timely basis to permit such sending or giving. The foregoing
indemnity agreement shall be in addition to any liability which the Company or
the Guarantors may otherwise have.

               (b)  If any action, suit or proceeding shall be brought against
an Initial Purchaser indemnified party in respect of which indemnity may be
sought against the Company or the Guarantors, the Initial Purchaser indemnified
party shall promptly notify the parties against whom indemnification is being
sought (the "indemnifying parties"), and such indemnifying parties shall assume
the defense thereof, including the employment of counsel and payment of all fees
and expenses. The Initial Purchaser indemnified party shall have the right to
employ separate counsel in any such action, suit or proceeding and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of the Initial Purchaser indemnified party unless (i)
the indemnifying parties have agreed in writing to pay such fees and expenses,
(ii) the indemnifying parties have failed to assume the defense and employ
counsel, or (iii) the named parties to any such action, suit or proceeding
(including any impleaded parties) include both the Initial Purchaser indemnified
party and the indemnifying parties and the Initial Purchaser indemnified party
shall have been advised by its counsel that representation of such indemnified
party and any indemnifying party by the same counsel would be inappropriate
under applicable standards of professional conduct (whether or not such
representation by the same counsel has been proposed) due to actual or potential
differing interests between them (in which case the indemnifying party shall not
have the right to assume the defense of such action, suit or proceeding on
behalf of the Initial Purchaser indemnified party). It is understood, however,
that the indemnifying parties shall, in connection with any one such action,
suit or proceeding or separate but substantially similar or related actions,
suits or proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the fees and expenses of only one
separate firm of attorneys (in addition to any local counsel) at any time for
all Initial Purchaser indemnified parties, which firm shall be designated in
writing by the Initial Purchaser, and that all such fees and expenses shall be
reimbursed on a monthly basis as provided in paragraph (a) hereof. The
indemnifying parties shall not be liable for any settlement of any such action,
suit or proceeding effected without their written consent, but if settled with
such written consent, or if there be a final judgment for the plaintiff in any
such action, suit or proceeding, the indemnifying parties agree to indemnify and

                                       20
<PAGE>
 
hold harmless the Initial Purchaser indemnified parties, to the extent provided
in paragraph (a), from and against any loss, claim, damage, liability or expense
by reason of such settlement or judgment.

               (c)  The Initial Purchaser agrees to indemnify and hold harmless
the Company and the Guarantors, their affiliates, any person who controls the
Company or the Guarantors within the meaning of Section 15 of the Act or Section
20 of the Exchange Act and any of their respective officers, directors,
employees or agents (the "Company indemnified parties") to the same extent as
the indemnity from the Company and the Guarantors to the Initial Purchaser
indemnified parties set forth in paragraph (a) hereof, but only with respect to
information relating to the Initial Purchaser furnished in writing by or on
behalf of the Initial Purchaser expressly for use in the Preliminary Offering
Memorandum or Offering Memorandum or any amendment or supplement thereto. If any
action, suit or proceeding shall be brought against the Company indemnified
parties based on the Preliminary Offering Memorandum or Offering Memorandum, or
any amendment or supplement thereto, and in respect of which indemnity may be
sought against the Initial Purchaser pursuant to this paragraph (c), the Initial
Purchaser shall have the rights and duties given to the Company and the
Guarantors by paragraph (b) above (except that if the Company and the Guarantors
shall have assumed the defense thereof such Initial Purchaser shall not be
required to do so, but may employ separate counsel therein and participate in
the defense thereof, but the fees and expenses of such counsel shall be at such
Initial Purchaser's expense), and the Company indemnified parties shall have the
rights and duties given to the Initial Purchaser indemnified parties by
paragraph (b) above. The foregoing indemnity agreement shall be in addition to
any liability which the Initial Purchaser may otherwise have.

               (d)  If the indemnification provided for in this Section 6 is
unavailable to an indemnified party under paragraphs (a) or (c) hereof in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then an indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Guarantors on the one hand and the Initial Purchaser on the
other hand from the offering of the Notes, or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred 

                                       21
<PAGE>
 
to in clause (i) above but also the relative fault of the Company and the
Guarantors on the one hand and the Initial Purchaser on the other in connection
with the statements or omissions that resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received by the Company and the Guarantors on the one hand
and the Initial Purchaser on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company bear to the total underwriting discounts and
commissions received by the Initial Purchaser, in each case as set forth in the
table on the cover page of the Offering Memorandum. The relative fault of the
Company and the Guarantors on the one hand and the Initial Purchaser on the
other hand shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the Company and the Guarantors
on the one hand or by the Initial Purchaser on the other hand and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

               (e)  The Company, the Guarantors and the Initial Purchaser agree
that it would not be just and equitable if contribution pursuant to this Section
6 were determined by a pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to in
paragraph (d) above. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, liabilities and expenses referred to in
paragraph (d) above shall be deemed to include, subject to the limitation set
forth in this Section 6, any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating any claim or defending any
such action, suit or proceeding. Notwithstanding the provisions of this Section
6, the Initial Purchaser shall not be required to contribute any amount in
excess of the amount by which the total price of the Notes underwritten by it
and distributed to the public exceeds the amount of any damages which the
Initial Purchaser has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

               (f)  Any losses, claims, damages, liabilities or expenses for
which an indemnified party is entitled to indemnification or contribution under
this Section 6 shall be

                                       22
<PAGE>
 
paid by the indemnifying party to the indemnified party as such losses, claims,
damages, liabilities or expenses are incurred. The indemnity and contribution
agreements contained in this Section 6 and the representations and warranties of
the Company and the Guarantors set forth in this Agreement shall remain
operative and in full force and effect, regardless of (i) any investigation made
by or on behalf of the Initial Purchaser or any persons controlling the Initial
Purchaser, the Company and the Guarantors, their directors or officers or any
person controlling the Company or the Guarantors, (ii) acceptance of any Notes
and payment therefore hereunder, and (iii) any termination of this Agreement. A
successor to the Initial Purchaser indemnified parties or to the Company shall
be entitled to the benefits of the indemnity, contribution and reimbursement
agreements contained in this Section 6.

               (g)  No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action, suit or proceeding in respect of which any indemnified party
is or could have been a party and indemnity could have been sought hereunder by
such indemnified party, unless such settlement includes an unconditional release
of such indemnified party from all liability on claims that are the subject
matter of such action, suit or proceeding.

          7.   Conditions of the Initial Purchaser's Obligations.  The
obligations of the Initial Purchaser to purchase the Notes are subject to the
following conditions:

               (a)  At the time of execution of this Agreement and on the
Closing Date, no order or decree preventing the use of the Offering Memorandum
or any amendment or supplement thereto, or any order asserting that the
transactions contemplated by the Agreement are subject to the registration
requirements of the Act shall have been issued and no proceedings for that
purpose shall have been commenced or shall be pending or, to the knowledge of
the Company, be contemplated. No stop order suspending the sale of the Notes in
any jurisdiction designated by any of the Initial Purchaser shall have been
issued and no proceedings for that purpose shall have been commenced or shall be
pending or, to the knowledge of the Company, shall be contemplated.

               (b)  Subsequent to the effective date of this Agreement, there
shall not have occurred (i) any change, or any development involving a
prospective change, in or affecting the condition (financial or other),
business, properties, net worth, or results of operations of the Company 

                                       23
<PAGE>
 
or the Subsidiary not contemplated by the Offering Memorandum, which in the
opinion of the Initial Purchaser, would materially adversely affect the market
for the Notes, or (ii) any event or development relating to or involving the
Company or any officer or director of the Company which makes any material
statement made in the Offering Memorandum untrue or which, in the opinion of the
Company and its counsel or the Initial Purchaser and its counsel, requires the
making of any addition to or change in the Offering Memorandum in order to state
a material fact required by any law to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, if amending or supplementing the Offering Memorandum
to reflect such event or development would, in the opinion of the Initial
Purchaser, materially adversely affect the market for the Notes.

               (c)  The Initial Purchaser shall have received on the Closing
Date an opinion of Conner & Winters, counsel for the Company dated the Closing
Date and addressed to the Initial Purchaser, to the effect that:

                    (i)  Each of the Company and Subsidiaries is a
     corporation duly incorporated and validly existing in good
     standing under the laws of its respective jurisdiction of
     incorporation with full corporate power and authority to own,
     lease and operate its respective properties and to conduct its
     respective business as described in the Offering Memorandum (and
     any amendment or supplement thereto), notwithstanding anything
     herein to the contrary, whenever the terms "Subsidiary,"
     "Subsidiaries," "Guarantor" and "Guarantors" are used in this
     Section 7(c), such shall exclude for all purposes the United
     Kingdom Subsidiary, the Australian -New Zealand Subsidiaries and
     the Canadian Subsidiary except where indicated;

                    (ii) Each of the Company and the Guarantors have
     the corporate power and authority to enter into this Agreement
     and the Registration Rights Agreement and, in the case of the
     Company, to issue, sell and deliver the Notes to be sold by it to
     the Initial Purchaser as provided herein, and this Agreement and
     the Registration Rights Agreement have been duly authorized,
     executed and delivered by the Company and the Guarantors and are
     the valid, legal and binding agreements of the Company and the
     Guarantors (including TES),

                                       24
<PAGE>
 
     enforceable against the Company and the Guarantors in accordance
     with their terms, except (A) as enforcement of rights to
     indemnity and contribution hereunder and thereunder may be
     limited by Federal or state securities laws or principles of
     public policy and (B) subject to the qualification that the
     enforceability of the Company's and the Guarantors's obligations
     hereunder and thereunder may be limited by bankruptcy, fraudulent
     conveyance, insolvency, reorganization, moratorium, and other
     similar laws affecting creditors' rights generally and by general
     equitable principles;

               (iii) The Indenture has been duly and validly
     authorized, executed and delivered by the Company and the
     Guarantors and, assuming due authorization, execution and
     delivery by the Trustee, is a valid and binding agreement of the
     Company and the Guarantors (including TES), enforceable in
     accordance with its terms, subject to the qualification that the
     enforceability of the Company's and the Guarantors's obligations
     thereunder may be limited by bankruptcy, fraudulent conveyance,
     insolvency, reorganization, moratorium, and other similar laws
     affecting creditors' rights generally and by general equitable
     principles; no qualification of the Indenture under the 1939 Act
     is required in connection with the offer and sale of the Notes
     contemplated hereby or in connection with the Exempt Resales;

               (iv)  The Notes have been duly and validly authorized
     by the Company and when executed by the Company in accordance
     with the Indenture and, assuming due authentication of the Notes
     by the Trustee, upon delivery to the Initial Purchaser against
     payment therefor in accordance with the terms hereof, will have
     been validly issued and delivered, and will constitute valid and
     binding obligations of the Company enforceable in accordance with
     their terms and entitled to the benefits of the Indenture,
     subject to the qualification that the enforceability of the
     Company's obligations thereunder may be limited by bankruptcy,
     fraudulent conveyance, insolvency, reorganization, moratorium,
     and other laws relating to or affecting creditors' rights
     generally and by general equitable principles;

               

                                       25
<PAGE>
 
               (v)     Neither the offer, sale or delivery of the
     Notes, the execution, delivery or performance by the Company and
     the Guarantors of this Agreement, the Registration Rights
     Agreement or the Indenture, compliance by the Company and the
     Guarantors with the provisions hereof or thereof nor consummation
     by the Company and the Guarantors of the transactions
     contemplated hereby or thereby conflicts or will conflict with or
     constitutes or will constitute a breach of, or a default under,
     the charter or by laws of the Company or the Subsidiary or any
     material agreement, indenture, lease or other instrument to which
     any of the Company or the Subsidiaries is a party or by which
     either of them or any of their properties is bound or results or
     will result in the creation or imposition of any lien, charge or
     encumbrance upon any property or assets of any of the Company or
     the Subsidiaries, nor will any such action result in any
     violation in any material respect of any existing law, of any
     regulation, ruling (assuming compliance with all applicable state
     securities and Blue Sky laws), judgment, injunction, order or
     decree known to such counsel, applicable to the Company, the
     Subsidiaries or any of their respective properties, provided that
     such counsel need express no opinion with respect to laws
     involving fraudulent conveyances;

               (vi)    The Guarantees have been duly and validly
     authorized by the Guarantors and when executed by the Guarantors
     in accordance with the Indenture and, assuming due authentication
     of the Notes by the Trustee, upon delivery to the Initial
     Purchaser against payment therefor in accordance with the terms
     hereof, will have been validly issued and delivered, and will
     constitute valid and binding obligations of the Guarantors
     (including TES) enforceable in accordance with their terms and
     entitled to the benefits of the Indenture, subject to the
     qualification that the enforceability of the Guarantors'
     obligations thereunder may be limited by bankruptcy, fraudulent
     conveyance, insolvency, reorganization, moratorium, and other
     laws relating to or affecting creditors' rights generally and by
     general equitable principles;

               (vii)   No consent, approval, authorization or other
     order of, or registration or filing with, any court, regulatory
     body,

                                       26
<PAGE>
 
     administrative agency or other governmental body, agency or
     official is required on the part of the Company for the valid
     issuance and sale of the Notes to the Initial Purchaser as
     contemplated by this Agreement and the Indenture (except such as
     may be required under securities or Blue Sky laws of various
     jurisdictions);

               (viii)  To the knowledge of such counsel after
     reasonable inquiry, other than as described in the Offering
     Memorandum (or any amendment or supplement thereto), there are no
     legal or governmental proceedings pending or threatened against
     the Company or the Subsidiaries or to which the Company or the
     Subsidiaries or any of their properties are subject, which, if
     adversely decided, are reasonably likely to cause a Material
     Adverse Effect or materially affect the issuance of the Notes or
     the consummation of the transactions contemplated by this
     Agreement;

               (ix)    The statements contained in the Offering
     Memorandum, insofar as they are descriptions of contracts,
     agreements or other legal documents, or refer to statements of
     law or legal conclusions, are, to the knowledge of such counsel
     after making reasonable inquiry, accurate in all material
     respects and present fairly the information required to be shown;

               (x)     Such counsel does not know of any person who
     has the right, contractual or otherwise, to cause the Company to
     sell or otherwise issue to them, or to permit them to underwrite
     the sale of, any of the Notes or the right, as a result of the
     consummation of the transactions contemplated by this Agreement
     and the Registration Rights Agreement, to require registration
     under the Act of any shares of Common Stock or other securities
     of the Company, other than the holders of the Notes;

               (xi)    When the Notes are issued and delivered
     pursuant to this Agreement, such Notes will not be of the same
     class (within the meaning of Rule 144A(d) (3) under the Act) as
     any security of the Company that is listed on a national
     securities exchange registered under Section 6 of the Exchange
     Act or that is quoted in a United State automated interdealer
     quotation system;

                                       27
<PAGE>
 
               (xii)   No registration of the Notes under the Act or
     qualification of the Indenture under the 1939 Act is required for
     the sale of the Notes to the Initial Purchaser or for the Exempt
     Resales in the manner contemplated by the Purchase Agreement and
     the Offering Memorandum;

               (xiii)  The Company is not required to obtain
     stockholder consent for the issuance of offering of the Notes;

               (xiv)   To the knowledge of such counsel after making
     reasonable inquiry, the Company is duly registered and qualified
     to conduct its business and is in good standing as a foreign
     corporation in each jurisdiction or place where the nature of its
     properties or the conduct of its business requires such
     registration or qualification, except where the failure so to
     register or qualify or to be in good standing does not have,
     individually or in the aggregate, a Material Adverse Effect;

               (xv)    All the outstanding shares of capital stock or
     other equity securities of each of the Subsidiaries have been
     duly authorized and validly issued, are fully paid and
     nonassessable, and the shares of each of the Subsidiaries
     (including the United Kingdom Subsidiary, the Australian -New
     Zealand Subsidiaries and the Canadian Subsidiaries) are owned by
     the Company, directly or through one or more Subsidiaries, and,
     to the knowledge of such counsel after making reasonable inquiry,
     with respect to such shares other than those of the United
     Kingdom Subsidiary, the Australian - New Zealand Subsidiary and
     the Canadian Subsidiary, are free and clear of any security
     interest, lien, adverse claim, equity or other encumbrance,
     except for (i) the lien and security interest held by the Bank of
     New Zealand in the shares of the Australian - New Zealand
     Subsidiaries, (ii) the right of first refusal on the El Dorado
     Nitrogen Company shares and (iii) any restrictions on transfer
     under the registration requirements of any federal or state
     securities laws;

               (xvi)   To the knowledge of such counsel after making
     reasonable inquiry, each of the Subsidiaries is duly registered
     and qualified

                                       28
<PAGE>
 
     to conduct its business and is in good standing as a foreign
     corporation in each jurisdiction or place where the nature of its
     properties or the conduct of its business requires such
     registration or qualification, except where the failure so to
     register or qualify or to be in good standing does not have,
     individually or in the aggregate, a Material Adverse Effect;

               (xvii)  To the knowledge of such counsel after making
     reasonable inquiry, neither the Company nor any of the
     Subsidiaries is in violation of its respective charter or bylaws,
     or is in default in the performance of any material obligation,
     agreement or condition contained in any bond, debenture, note or
     other evidence of indebtedness or in any material agreement,
     indenture, lease or other instrument to which the Company or any
     of the Subsidiaries is a party or by which any of them or any of
     their respective properties may be bound, except for violations
     or defaults which would not have, singly or in the aggregate, a
     Material Adverse Effect or except as described in the Offering
     Memorandum (or any amendment or supplement thereto);

               (xviii) To the knowledge of such counsel after making
     reasonable inquiry, neither the Company nor any of the
     Subsidiaries is in violation in any material respects of any
     decree of any court or governmental agency or body having
     jurisdiction over the Company or any of the Subsidiaries, except
     for violations which would not, singly or in the aggregate, have
     a Material Adverse Effect and except as disclosed or referenced
     in the Offering Memorandum (or any amendment or supplement
     thereto);

               (xix)   All the shares of capital stock of the Company
     outstanding prior to the issuance of the Notes have been duly
     authorized and validly issued and are fully paid and
     nonassessable; and

               (xx)    Although such counsel has not undertaken,
     except as otherwise indicated in their opinion, to determine
     independently, and does not assume any responsibility for, the
     accuracy, completeness or fairness of the statements contained in
     the Offering Memorandum, such counsel has participated in the
     preparation of the Offering

                                       29
<PAGE>
 
     Memorandum, including review and discussion of the contents
     thereof, and nothing has come to the attention of such counsel
     that has caused them to believe that the Offering Memorandum, as
     of its date and as of the Closing Date, contained an untrue
     statement of material fact or omitted to state a material fact
     required to be stated therein or necessary to make the statements
     therein, in light of the circumstances under which they were
     made, not misleading or that any amendment or supplement to the
     Offering Memorandum, as of its respective date and as of the
     Closing Date, contained any untrue statement of a material fact
     or omitted to state a material fact required to be stated therein
     or necessary in order to make the statements therein, in light of
     the circumstances under which they were made, not misleading (it
     being understood that such counsel need express no opinion with
     respect to the financial statements and the notes thereto and the
     schedules and other financial and statistical data included in
     the Offering Memorandum).

     Such opinion may state (A) as to the enforceability of the Indenture, the
Registration Rights Agreement and this Agreement, that such counsel assumes that
the laws of the State of New York which affect enforceability are not different
from the laws of the State of Oklahoma, (B) as to matters of Australian law, it
is relying on the opinion of Corrs Chambers Westgarth and (C) it is assuming
that the transactions contemplated by the Indenture, the Registration Rights
Agreement and this Agreement do not conflict with or constitute a default under
(i) any Australian law, rule, or regulation to which the Company, the Guarantors
or any of their properties is subject,  (ii) any judicial or regulatory order or
decree of any Australian governmental authority, (iii) any consent, approval,
license, authorization or validation of, or filing, recording or registration
with any Australian governmental authority, and (iv) there is nothing to
preclude this Agreement, the Registration Rights Agreement and Indenture from
being a valid and binding agreement under Australian law.

          (d)  The Initial Purchaser shall have received on the Closing Date an
opinion of Corrs Chambers Westgarth, counsel for TES dated the Closing Date and
addressed to the Initial Purchaser, to the effect that:

               (i)     TES is a corporation duly incorporated and
     validly existing in good standing

                                       30
<PAGE>
 
     under the laws of its jurisdiction of incorporation;

               (ii)    TES has the corporate power and authority to
     enter into this Agreement, the Registration Rights Agreement and
     the Indenture, and this Agreement, the Registration Rights
     Agreement and the Indenture have been duly autho rized, executed
     and delivered by TES, subject to TES receiving valid benefits
     under the Guarantee; and

               (iii)   The Guarantee has been duly and validly
     authorized by TES, subject to TES receiving valid benefits under
     the Guarantee.

          (e)  The Initial Purchaser shall have received on the Closing Date an
opinion of Skadden, Arps, Slate, Meagher & Flom LLP, special counsel for the
Initial Purchaser, dated the Closing Date, and addressed to the Initial

     may hereafter be amended, no director of this Corporation shall be liable
     to this Corporation or its shareholders for monetary damages for breach of

     director's duty of loyalty to the Corporation or its shareholders, or (b)
     for acts or omissions not in good faith or which involve intentional

     the Oklahoma General Corporation Act, the directors will by vote at a
     special meeting, immediately called for such purpose or by unanimous
     written consent, to determine whether such person has met the standards of
     conduct set forth in Section 1031(A) or (B) of the Oklahoma General
     Corporation Act, as amended, whichever is applicable, subject to the
     provisions of Section 1031(D)(1) and (2) of the Oklahoma General

consents shall have the right to do so either in person or by one or more agents
authorized by proxy. The appointment of a proxy shall be in writing and signed
by the shareholder but shall require no other attestation and shall be filed
with the Secretary of the Corporation at or prior to the meeting. If any
shareholder appoints two or more persons to act as proxies and if the instrument
does not otherwise provide, then a majority of such persons present at the
meeting, or if only one shall be present, then that one shall have and may
exercise all of the powers conferred by such instrument upon all of the persons
so appointed; and if such proxies be equally divided as to the right and manner
of voting in any particular case, the vote shall be divided among the proxies.
Any person holding shares in a representative or fiduciary capacity which he may
represent in person may represent the same by proxy and confer general or
discretionary power upon such a proxy. The duly executed proxy will be
irrevocable and if, and only as long as, it is coupled with an interest
sufficient in law to support an irrevocable power. The authority of a proxy if
not coupled with an interest may be terminated at will. Unless otherwise
provided in the appointment, the proxy's authority shall cease three (3) years
after the appointment. The termination of a proxy's authority by act of the
shareholder shall, subject to the time limitation herein set forth, be
ineffective until written notice of the termination has been given to the
Secretary of the Corporation. Unless otherwise provided therein, an appointment
filed with the Secretary shall have the effect of revoking all proxy
appointments of prior date. A proxy's authority shall not be revoked by the
death or incapacity of the maker unless before the vote is cast or the authority
is exercised written notice of such death or incapacity is given to the
Secretary of the Corporation.

without a vote if a consent in writing be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take action at a meeting at which all shares entitled to vote

of a quorum, the authenticity, validity and effect of proxies; receiving votes,
ballots or consents; hearing and determining all challenges and questions in any
way arising in connection with the right to vote; counting and tabulating all

of the election shall perform their duties impartially in good faith, to the
best of their ability, and as expeditiously as is practical. If there be three
inspectors, the decision, act or certificate of a majority shall be effective in
all respects as the decision, act, or certificate of all.

manner in which he reasonably believed to be in or not opposed to the best

proceeding, had reasonable cause to believe that his conduct was unlawful.

Directors, as the case may be, or standing registered in his name at the time of
such meeting if neither a date for the closing of the transfer books nor a
record date for such meeting has been fixed by the Board of Directors. The
voting at all meetings of shareholders may be viva voce but any qualified voter
may demand a share vote by written ballot, whereupon such share vote shall be
taken by written ballot each of which shall state the name of the shareholder
voting and the number of shares voted by him, and if such ballot be cast by
proxy, it shall also state the name of such proxy.

consents shall have the right to do so either in person or by one or more agents
authorized by proxy. The appointment of a proxy shall be in writing and signed
by the shareholder but shall require no other attestation and shall be filed
with the Secretary of the Corporation at or prior to the meeting. If any
shareholder appoints two or more persons to act as proxies and if the instrument
does not otherwise provide, then a majority of such persons present at the
meeting, or if only one shall be present, then that one shall have and may
exercise all of the powers conferred by such instrument upon all of the persons
so appointed; and if such proxies be equally divided as to the right and manner
of voting in any particular case, the vote shall be divided among the proxies.

represent in person may represent the same by proxy and confer general or
discretionary power upon such a proxy. The authority of a proxy if not coupled
with an 

                                       3

interest may be terminated at will, unless otherwise provided in the
appointment, the proxy's authority shall cease three (3) years after the
appointment. The termination of a proxy's authority by act of the shareholder
shall, subject to the time limitation herein set forth, be ineffective until
written notice of the termination has been given to the Secretary of the
Corporation. Unless otherwise provided therein, an appointment filed with the
Secretary shall have the effect of revoking all proxy appointments of prior
date. A proxy's authority shall not be revoked by the death or incapacity of the
maker unless before the vote is cast or the authority is exercised written
notice of such death or incapacity is given to the Corporation.

      Section 2.9   Order of Business. The order of business at the annual

shares represented at the meeting, the existence of a quorum, the authenticity,

decision, act or certificate of a majority shall be effective in all respects as
the decision, act, or certificate of all.

reason of the fact that he is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses, including attorneys' fees,
judgments,fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner in which he reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

      Section 9.2   Indemnification: Actions by the Corporation. The Corporation
                    -------------------------------------------                 
shall have the power to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses, including attorneys' fees,
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his duty to the
Corporation unless and only to the extent that the court in which such action or
suit was brought shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such court
shall deem proper.

made by the Corporation only as authorized in the specific case upon a
determination that indemnification of the director, officer, employee or agent
is proper in the circumstances because he has met the applicable standard of
conduct set forth in Sections 9.1 and 9.2 of this Article IX. Such determination
shall be made: (a) by the Board of Directors by a majority vote of a quorum

paid by the Corporation in advance of the final disposition of such action, suit

director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Article IX with respect to the resulting or surviving corporation as he
would have with respect to such constituent corporation if its separate

or voidable solely for this reason, or solely because the director or officer is
present at or participates in the meeting of the Board of Directors or a
committee thereof which authorizes the contract or transaction, or solely

facts as to the relationship or interest and as to the contract or transaction

required to be exercised or done by the stockholders.

     Section 12.    Unless otherwise restricted by the Certificate of
Incorporation or these By-Laws, the Board of Directors shall have the authority

the corporation in any other capacity and receiving compensation therefor.
Members of special or standing committees may be allowed like compensation for
attending committee meetings.

                                INDEMNIFICATION
                                ---------------

     Section 13(a). The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by-
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or .is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect 

                                       10
<PAGE>
 
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

     (b)  The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no such indemnification shall be made in respect of
any claim, issue or matter as to which such person shall have been adjudged to
be liable for negligence or misconduct in the performance of his duty to the
corporation unless and only to the extent that the Court of 

                                       11
<PAGE>
 
Chancery of Delaware or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which such Court of Chancery or such
other court shall deem proper.

     (c)  To the extent that a director, officer, employee or agent of the
corporation shall be successful on the merits or otherwise in defense, of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

     (d)  Any indemnification under paragraphs (a) and (b) (unless ordered by a
court) shall be made by the corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in paragraphs (a) and (b). Such determination shall be made
(1) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or (2) if
such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by independent legal counsel in a written
opinion, or (3) by the stockholders.

                                       12
<PAGE>
 
     (e)  Expenses incurred in defending a civil or criminal action, suit or
proceeding may be paid by the corporation in advance of the final disposition of
such action, suit or proceeding as authorized by the Board of Directors in the
manner provided in paragraph (d) upon receipt of an undertaking by or on behalf
of the director, officer, employee or agent to repay such amount unless it shall
ultimately be determined that he is entitled to be indemnified by the
corporation as authorized in this Section 13.

     (f)  The indemnification provided by this Section 13 shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any statute, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

     (g)  The Board of Directors may authorize, by a vote of a majority of a
quorum of the Board of Directors, the corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation 

                                       13
<PAGE>
 
would have the power to indemnify him against such liability under the
provisions of this Section 13.

     (h)  For the purposes of this Section 13, references to "the corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Section with
respect to the resulting or surviving corporation as he would have with respect
to such constituent corporation if its separate existence had continued.

5.01 Lien for Indebtedness.  Subject to the Act, the Corporation has a lien on
     ---------------------                                                    
shares registered in the name of a shareholder or his legal representative for a
debt of that shareholder to the Corporation.  The Corporation may enforce the

     (i)    in the case of a lien on redeemable shares, redeeming the shares at

     shareholder and paying any balance to 

                                      -7-
<PAGE>
 
     the shareholder. If such redemption is made solely for the purpose of
     enforcing such lien, then subject to any provision to the contrary
     contained in the Act or the Articles the Corporation shall not be obliged
     to redeem any shares other than the redeemable shares being redeemed for
     such purpose; and

     (ii)   in the case of any such shares, including redeemable shares, by
     selling such shares or such portions thereof as the directors may from time
     to time in their discretion determine to such persons and on such terms as
     the directors may in their discretion have authorized, provided that not
     less than 30 days prior to the date of such sale the Corporation shall have
     provided a notice to such shareholder or his legal representative demanding
     payment of the debt and advising such shareholder or his legal
     representative that unless such debt together with any interest accruing
     thereon up to the time of payment shall have been paid within such 30 days,
     the Corporation may thereafter without further notice to such shareholder
     or his legal representative effect a sale of all or any part of the shares
     of such shareholder pursuant to this provision.  Such notice may be given
     by prepaid ordinary mail addressed to the shareholder at his last known
     address appearing on the records of the Corporation and in the event of
     such mailing such notice shall be deemed to have been received three days
     after the mailing thereof.  The Corporation may, in lieu of such notice,
     advertise such notice at least 30 days before the intended date of the sale
     in a daily newspaper of general circulation published or distributed in the
     place where the Corporation has its registered office.  The title of such
     shareholder or his legal representative to any such shares so sold shall,
     by that sale, be divested and transferred to the respective purchasers of
     such shares.  The proceeds of such shale shall be applied, firstly, to pay
     the reasonable costs and expenses incurred by the Corporation in providing
     such notice or making such advertisement and in effecting such sale, and
     nextly pro tanto on account of a payment of all indebtedness then owing by
     such shareholder to the Corporation, and any balance thereafter remaining
     shall be paid to such shareholder or his legal representative.

     Any sums which are payable by the Corporation to a shareholder or his legal
representative pursuant to this section shall not bear interest unless payment
thereof shall have been demanded by such shareholder or his legal representative
and the Corporation shall have failed to pay the sum owing within a period of
five days after such demand.  In lieu of making payment of any sum which is
payable 

                                      -8-

to a shareholder or his legal representative pursuant to this section, the
Corporation may deposit such sum to the credit of such shareholder or his legal
representative with any Canadian chartered bank or trust company having an
office in the City of Toronto, Ontario, and such deposit shall be deemed to
satisfy all obligations of the Corporation to pay the sum so deposited to such
shareholder or his legal representative.

     The enforcement of a lien pursuant to this section shall be without
prejudice to any other right which the Corporation may have to enforce the lien
which may in law be available to it or to any remedy available to the
Corporation for collection of the debt or any part thereof.

books of the corporation in respect of such joint holders the cheque shall be
mailed to the first address so appearing.  The mailing of such cheque as
aforesaid shall satisfy and discharge all liability for the dividend to the
extent of the sum represented thereby, unless such cheque shall not be paid on
presentation.  Upon proof being given to the Corporation of the non-receipt of

                           ------------------------

                    ---------------

holding not less than one-fourth (1/4) of the issued and outstanding voting
shares of the Corporation. Notice of such special meetings shall be given in the

seven (7) days after the receipt of such request, such person or persons making
such request may fix the time of such special meeting and give notice thereof in
the same manner as herein provided for notice of special meetings of
shareholders.

      Section 2.3   Place of Meetings. All meetings of shareholders shall be
                    -----------------
held either at the principal office of the Corporation or at any other place

      Section 2.4   Notice of Meetings. Written notice of the time, date and
                    ------------------                                      
place of each annual meeting of the shareholders shall be given to each
shareholder as described in Section 10.4 not less than ten (10) nor more than
sixty (60) days before each annual meeting.

      Section 2.5   Voting List. The Secretary shall prepare, at least forty-
                    -----------                                             
eight (48) hours prior to each meeting of the shareholders, an alphabetical list
of all shareholders entitled to vote at such meeting, with the number of shares
entitled to be voted by each shareholder set forth opposite their respective
names. The Secretary shall produce the share ledger or a duplicate thereof,
together with such list and shall keep it open either at a place within the city
where the meeting is to be held, which place shall be specified in the notice of
the meeting, or, if not so specified, at the place where the meeting is to be
held during the business hours of at least one (1) full day immediately
preceding the convening thereof and until the close of such meeting, and it
shall be subject to inspection at any time during such period by any shareholder
or person representing shares. However, the Secretary shall not be required to
prepare and produce a list of shareholders in any case where the share ledger
reasonably shows in alphabetical order by classes of shares all persons entitled
to represent shares at such meeting with the number of shares entitled to be
voted by each shareholder.

      Section 2.6   Quorum and Required Vote; Adjourned Meetings. The holders of
                    --------------------------------------------                
a majority of the stock issued and outstanding and entitled to vote thereat,
present in person or represented by proxy, shall constitute a quorum at all
meetings of the

                                       2
<PAGE>
 
shareholders for the transaction of business, except as otherwise provided by
statute or the Certificate of Incorporation of the Corporation. When a quorum is
present at any meeting, a majority of the shares represented thereat and
entitled to vote thereat shall decide any question brought before such meeting.
The shareholders present at a duly called or held meeting at which a quorum is
present may continue to do business until adjournment, notwithstanding the
withdrawal of enough shareholders to leave less than a quorum. Any shareholders'
meeting, annual or special, whether or not a quorum is present, may be adjourned
from time to time by the holders of a majority of the shares entitled to vote
thereat, present in person or by proxy, but in the absence of a quorum no other
business may be transacted at such meeting. It shall not be necessary to give
any notice of the time and place of the adjourned meeting or of the business to
be transacted thereat, other than by announcement at the meeting at which such
adjournment is taken, except that if any shareholders' meeting, either annual or
special, is adjourned for thirty (30) days or more, notice of the adjourned
meeting shall be given as in the case of an original meeting.

      Section 2.7   Voting. At each meeting of shareholders each shareholder
                    ------                                                  
entitled to vote shall vote in person or by proxy and he shall have one vote for
each share standing registered in his name at the closing of the transfer books
for such meeting, or the record date fixed for such meeting by the Board of
Directors, as the case may be, or standing registered in his name at the time of
such meeting if neither a date for the closing of the transfer books nor a
record date for such meeting has been fixed by the Board of Directors. The
voting at all meetings of shareholders may be viva voce but any qualified voter
may demand a share vote by written ballot, whereupon such share vote shall be
taken by written ballot each of which shall state the name of the shareholder
voting and the number of shares voted by him, and if such ballot be cast by
proxy, it shall also state the name of such proxy.

      Section 2.8   Proxies. Any shareholder entitled to vote or execute
                    -------
consents shall have the right to do so either in person or by one or more agents
authorized by proxy. The appointment of a proxy shall be in writing and signed
by the shareholder but shall require no other attestation and shall be filed
with the Secretary of the Corporation at or prior to the meeting. If any
shareholder appoints two or more persons to act as proxies and if the instrument
does not otherwise provide, then a majority of such persons present at the
meeting, or if only one shall be present, then that one shall have and may
exercise all of the powers conferred by such instrument upon all of the persons
so appointed; and if such proxies be equally divided as to the right and manner
of voting in any particular case, the vote shall be divided among the proxies.
Any person holding shares in a representative or fiduciary capacity which he may
represent in person may represent the same by proxy and confer general or
discretionary power upon

                                       3
<PAGE>
 
such a proxy. The authority of a proxy if not coupled with an interest may be
terminated at will, unless otherwise provided in the appointment, the proxy's
authority shall cease three (3) years after the appointment. The termination of
a proxy's authority by act of the shareholder shall, subject to the time
limitation herein set forth, be ineffective until written notice of the
termination has been given to the Secretary of the Corporation. Unless otherwise
provided therein, an appointment filed with the Secretary shall have the effect
of revoking all proxy appointments of prior date. A proxy's authority shall not
be revoked by the death or incapacity of the maker unless before the vote is
cast or the authority is exercised written notice of such death or incapacity is
given to the Corporation.

      Section 2.9   Order of Business. The order of business at the annual
                    -----------------                                     
meeting, and so far as practicable at all other meetings of the shareholders,
shall be as follows:

          (a)  Calling meeting to order;

          (b)  Calling of roll and checking proxies;

          (c)  Proof of notice of meeting;

          (d)  Reading of any unapproved minutes;

          (e)  Reports of officers;

          (f)  Reports of committees;

          (h)  Unfinished business;

          (i)  New business; and

      Section 2.10  Action Without Meeting.  Any action which, under any
                    ----------------------

                    ----------------------                              
shareholders, the Board of Directors may appoint Inspectors of Election to act
at such meeting or any adjournment thereof. If Inspectors of Election be not so
appointed, the Chairman of any such meeting may, and on the request of any
shareholder or his proxy shall, make such appointment at the meeting. The number
of inspectors shall be either one or three. If appointed at a meeting on the
request of one or more shareholders or proxies, the majority of shares present
shall determine whether one or three inspectors are to be appointed. In case any
person appointed as inspector fails or refuses to act, the vacancy may be filled
by appointment by the Board of Directors in advance of the meeting, or at the
meeting by the Chairman. An inspector need not be a shareholder of the
Corporation, but no person who is a candidate for office of the Corporation
shall act as an inspector. The duties of such inspectors shall include:
determining the number of shares outstanding and the voting power of each, the
shares represented at the meeting, the existence of a quorum, the authenticity,
validity and effect of proxies; receiving votes, ballots or consents; hearing
and determining all challenges and questions in any way arising in connection
with the right to vote; counting and tabulating all votes or consents;
determining the result; and such acts as may be proper to conduct the election
or vote with fairness to all shareholders. The inspectors of the election shall
perform their duties impartially in good faith, to the best of their ability,
and as expeditiously as is practical. If there be three inspectors, the
decision, act or certificate of a majority shall be effective in all respects as
the decision, act, or certificate of all.

director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses, including attorneys' fees,

faith and in a manner he reasonably believed to be in or not opposed to the best

proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of

director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses, including attorneys' fees,
actually and reasonably incurred by him in connection with the defense or

reasonably believed to be in or not opposed to the best interests of the
Corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his duty to the
Corporation unless and only to the extent that the court in which such action or
suit was brought shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such court
shall deem proper.

conduct set forth in Sections 9.1 and 9.2 of this Article IX. Such determination
shall be made: (a) by the Board of Directors by a majority vote of a quorum
consisting of directors who were not parties to such action, suit or proceeding;

disinterested directors so directs, by independent legal counsel in a written

or voidable solely for this reason, or solely because the director or officer is
present at or participates in the meeting of the Board of Directors or a
committee thereof which authorizes the contract or transaction, or solely
because his or their votes are accounted for such purpose; if: (a) the material
facts as to the relationship or interest and as to the contract or transaction

the Board of Directors shall approve, including, without limitation, a pledge of
shares of stock of the Corporation. Nothing contained in this section shall be
construed to deny, limit or restrict the powers of guaranty or warranty of any
Corporation at common law or under any statute.

                    ---------                                                  
repealed at any annual or special meeting of the shareholders, provided notice
of the proposed amendment, alteration, change or repeal is contained in the
notice of such meeting, by the affirmative vote of a majority of the shares
issued and outstanding, and entitled to vote thereat. These Bylaws also may be
amended, altered, changed or repealed at any annual or special meeting of the
Board of Directors, provided notice of the proposed amendment, alteration,
change or repeal is contained in the notice of such meeting, by the affirmative
vote of the members of the Board of Directors. Notwithstanding the preceding

     (d) All or any part of the Preferred shares may be redeemed at any time by
     the directors upon thirty (30) days notice to the holders thereof and the
     payment of $100.00 for each of such shares to be redeemed. The directors
     may, in their sole discretion, determine which of the Preferred shares
     shall be so redeemed without regard to the identity of the holder or
     holders, and shall not be required to prorate such redemption.

     (e) In the event of a voluntary or involuntary winding up or distribution
     or liquidation or partial liquidation of this Corporation, the holders of

               ----------------

purpose or purposes.

     3.03.     Place of Meetings.  The Shareholders shall hold all meetings at
               -----------------

     3.04.     Notice of Meetings.  Except as otherwise required by law, the
               ------------------                                           
Board or a committee of the Board shall give notice of each meeting of
Shareholders, whether annual or special, not less than 10 nor more than 60 days
before the date of the meeting. The Board or a committee of the Board shall
deliver a notice to each Shareholder entitled to vote at such meeting by
delivering a typewritten or printed notice thereof to him personally, or by
depositing such notice in the United States mail, in a postage prepaid envelope,
directed to him at his address as it appears on the records of the Corporation,

notice of such meeting, except when the person attends the meeting for the
express

                                       2

purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. No written

purpose or purposes of any regular or special meeting of the Shareholders,
directors or members of a committee of the Board.

     3.06.     Adjournment of Meeting.  When the Shareholders adjourn a

adjournment is taken. At the adjourned meeting, the Shareholders may transact
any business which they may have transacted at the original meeting. If the
adjournment is for more than 30 days or, if after the adjournment, the Board or

each Shareholder of record entitled to vote at the meeting.

     3.07.     Quorum.  Except as otherwise required by law, the holders of a
               ------                                                        
majority of all of the shares of the stock entitled to vote at the meeting,
present in person or by proxy, shall constitute a quorum for all purposes at any
meeting of the Shareholders. In the absence of a quorum at any meeting or any
adjournment thereof, the holders of a majority of the shares of stock entitled
to vote who are present, in person or by proxy, or, in the absence therefrom of
all the Shareholders, any officer entitled to preside at, or to act as secretary
of, such meeting may adjourn such meeting to another place, date or time.

     If the chairman of the meeting gives notice of any adjourned special
meeting of Shareholders to all Shareholders entitled to vote thereat, stating
that those present shall constitute a quorum, then, except as otherwise required
by law, those present at such adjourned meeting shall constitute a quorum and a
majority of the votes cast at such meeting shall determine all matters.

     3.08.     Organization.  Such person as the Board may have designated or,
               ------------

who is present shall call to order any meeting of the Shareholders, determine

the Secretary or an Assistant Secretary of the Corporation, the chairman shall
appoint the secretary of the meeting.

     3.09.     Conduct of Business.  The chairman of any meeting of
               -------------------                                 
Shareholders shall determine the order of business and the procedure at the
meeting, including such regulations of the manner of voting and the conduct of

and the number of shares registered in the name of each Shareholder. The
Corporation shall make the list available for examination by any Shareholder for
any purpose germane to the meeting, either at a place within the city where the
meeting will take place or at the place designated in the notice of the meeting.

     The Secretary shall produce and keep the list at the meeting during the
entire duration of the meeting, and any Shareholder who is present may inspect
the list at the meeting. The list shall constitute presumptive proof of the
identity of the Shareholders entitled to vote at the meeting and the number of
shares each Shareholder holds.

receive payment of any dividend, or in order to make a determination of
Shareholders for any other proper purpose, the Board or a committee of the Board
may provide that the Corporation shall close the stock transfer books for a
stated period not to exceed 60 days. if the Corporation closes the stock
transfer books for the purpose of determining Shareholders entitled to notice of

the Board may fix in advance a date as the record date for any such
determination of Shareholders. However, the Board shall not fix such date, in
any case, more than 60 days prior to the date of the particular action.

     If the Board or a committee of the Board does not close the stock transfer
books and does not fix a record date for the determination of Shareholders
entitled to notice of or to vote at a meeting of Shareholders, the date of the
mailing of notice or the date on which the Board adopts the resolution declaring
a dividend, as the case may be, shall be the record date for such determination
of Shareholders.

     3.12.     Voting of Shares.  Each Shareholder shall have one vote for
               ----------------                                           
every share of stock having voting rights registered in his name on the record
date for the meeting. The Corporation shall not have the right to vote treasury
stock of the Corporation, nor shall another corporation have the right to vote

<PAGE>
 
directors of such other corporation. Persons holding stock of the Corporation in
a fiduciary capacity shall have the right to vote such stock. Persons who have
pledged their stock of the Corporation shall have the right to vote such stock
unless in the transfer on the books of the Corporation the pledgor expressly
empowered the pledgee to vote such stock. In that event, only the pledgee, or
his proxy, may represent such stock and vote thereon.

     A plurality of the votes cast shall determine all elections and, except
when the law requires otherwise, a majority of the votes cast shall determine
all other matters.

     The Shareholders may vote by voice vote on all matters. However, upon
demand by a Shareholder entitled to vote, or his proxy, the Shareholders shall
vote by ballot. In that event, each ballot shall state the name of the
Shareholder or proxy voting, the number of shares voted and such other
information as the Corporation may require under the procedure established for
the meeting.

impartiality, and according to the best of his ability. The judge or judges
shall decide the qualification of the voters and shall report the number of
shares represented at the meeting and entitled to vote on any question, shall
conduct and accept the votes, and, when the Shareholders have completed voting,
ascertain and report the number of shares voted respectively for and against the
question. The judge or judges shall prepare a subscribed, written report and
shall deliver the report to the Secretary of the Corporation. A judge need not
be a Shareholder of the Corporation, and any officer of the Corporation may be a
judge on any question other than a vote for or against a proposal in which he
has a material interest.

     3.14.     Proxies.  A Shareholder may exercise any voting rights in
               -------                                                  
person or by his proxy appointed by an instrument in writing, which he or his
authorized attorney-in-fact has subscribed and which the proxy has delivered to
the secretary of the meeting.

     A proxy is not valid after the expiration of three years after the date of
its execution, unless the person executing it specifies thereon the length of
time for which it is to continue in force (which length may exceed three years)
or limits its use to a particular meeting.

     The attendance at any meeting of a Shareholder who previously has given a
proxy shall not have the effect of revoking the same unless he notifies the
Secretary in writing prior to the voting of the proxy.

Corporation shall have the right to receive a certificate or certificates,
certifying to the number and class of shares of the stock of the Corporation
which he owns. The Board shall determine the form of the certificates for the
shares of stock of the Corporation. The Secretary, transfer agent, or registrar
of the Corporation shall number the certificates representing shares of the
stock of the Corporation in the order in which the Corporation issues them. The
President or any vice President and the Secretary or any Assistant Secretary
shall sign the certificates in the name of the Corporation. Any or all
certificates may contain facsimile signatures. In case any officer, transfer
agent, or registrar who has signed a certificate, or whose facsimile signature
appears on a certificate, ceases to serve as such officer, transfer agent, or
registrar before the Corporation issues the certificate, the Corporation may
issue the certificate with the same effect as though the person who signed such
certificate, or whose facsimile signature appears on the certificate, was such
officer, transfer agent, or registrar at the date of issue. The Secretary,
transfer agent, or registrar of the Corporation shall keep a record in the stock
transfer books of the Corporation of the names of the persons, firms or
corporations owning the stock represented by the certificates, the number and
class of shares represented by the certificates and the dates-thereof and, in

Corporation's stock, or his attorney-in-fact authorized by power of attorney
duly executed and filed with the Secretary, transfer agent or registrar of the
Corporation, may transfer his shares only on the stock transfer books of the
Corporation. Such person shall furnish to the Secretary, transfer agent, or
registrar of the Corporation proper evidence of his authority to make the
transfer and shall properly endorse and surrender for cancellation his existing
certificate or certificates for such shares. Whenever the holder of record of
shares of the Corporation's stock makes a transfer of shares for collateral
security, the Secretary, transfer agent, or registrar of the Corporation shall
state such fact in the entry of transfer if the transferor and the transferee
request.

     9.03.     Lost, Stolen, Destroyed and Mutilated Certificates. The Board

issue a new certificate to any holder of record of shares of the Corporation's
stock claiming that he has lost such certificate, or that someone has stolen,
destroyed or mutilated such certificate, upon the receipt of an affidavit from
such holder to such fact. When authorizing the issue of a new certificate, the
Board, in its discretion, may require as a condition precedent to the issuance
that the owner of such certificate give the Corporation a bond of indemnity in
such form and amount as the Board may direct.

     9.04.     Regulations.  The Board may make such rules and regulations,
               -----------

all certificates for stock to bear the signature or signatures of any of them.

     9.05.     Holder of Record.  The Corporation may treat as absolute owners
               ----------------

had full competency, capacity and authority to exercise all rights of ownership,
despite any knowledge or notice to the contrary or any description indicating a
representative, pledge or other fiduciary relation, or any reference to any
other instrument or to the rights of any other person appearing upon its record

furnishing proof of his appointment as a fiduciary as if he were the holder of
record of the shares.

     9.06.     Treasury Shares.  Treasury shares of the Corporation shall

     have any effect on the liability or alleged liability of any officer,
     director, employee or agent of this Corporation for or with respect to any
     acts or omissions of such person occurring prior to the time of such
     amendment or repeal. On the request of any person who believes he is

     Directors or in the Bylaws of the Corporation. Elections of Directors need
     not be by written ballot unless the Bylaws of the Corporation so provide.

E.   To the fullest extent permitted by law, no contract or transaction between
     the Corporation and one or more of the Corporation's Directors or officers,
     or between the Corporation and any other corporation, partnership,
     association or other organization in which one or more of the Corporation's
     Directors or officers are directors or officers or have a financial
     interest, shall be void or voidable solely for this reason, or solely

     Directors or committee thereof which authorizes the contract or
     transaction, or solely because the Corporation's Directors or officers or
     their votes are counted for such purposes.

F.   To the fullest extent that the Act permits the limitation or elimination of
     the liability of Directors, no director shall be personally liable to the
     corporation or its shareholders for monetary damages for breach of
     fiduciary duty as a director; provided that such provision shall not
     eliminate or limit the liability of a director (a) for any breach of the
     director's duty of loyalty to the corporation or its shareholder, or (b)
     for acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of the law, or (c) under Section 1053 of

     -------------

second Tuesday in April of each year; provided that any such meeting may be held
at any other time designated by the Board or by the majority of the shareholders
entitled to vote at such meeting. At such annual meetings, directors will be
elected, reports of affairs of the Corporation will be considered and any other
business may be transacted which is within the powers of the shareholders to
transact and which may be properly brought before the meeting.

3.3  Special Meetings. Special meetings of the shareholders may be called for
     ----------------                                                        
any purpose by the president (or, in his absence or disability, by a vice
president), by the Board, or by a notice signed by shareholders holding a
majority or more of the issued and outstanding voting shares of the Corporation.
Upon a request being made by written notice to the president or, in his absence
or disability, to a vice president, or to the secretary, by any person or
persons herein empowered to call a special meeting, if such officer is the
secretary, he will give notice to the shareholders or, if such officer is other
than the secretary, he will cause the secretary to give notice to the
shareholders that such meeting has been called for the purpose or purposes
stated in such request and is to be held at a specified time, which time will
not be less than ten (10) days or more than sixty (60) days after the receipt of
such request. If notice of such meeting is not given to the shareholders within
seven (7) days after the receipt of such request, such person or persons making
such request may fix the 
<PAGE>
 
time of such special meeting and give notice thereof in the same manner as
hereinafter provided.

3.4  Notice of Meeting. Subject to the provisions of paragraph 3.11 hereof, a
     -----------------                                                       
written notice of each meeting of the shareholders stating the date, hour and
place and in case of special meetings the purpose thereof, will be mailed by the
secretary of the Corporation, postage prepaid, to each shareholder entitled to
vote, at such address as appears on the books of the Corporation, at least ten
(10) days but not more than sixty (60) days before the date of each meeting.

3.5  Quorum. A majority of the issued and outstanding shares entitled to vote
     ------                                                                  
(exclusive of treasury shares, if any) will constitute a quorum at meetings of
shareholders. When a quorum is present, a majority of the shares represented and
entitled to vote at the meeting will decide any question brought before such
meeting. In the absence of a quorum, those shareholders present may adjourn the
meeting from time to time until a quorum is obtained, but until a quorum is
obtained, no other business may be transacted.

3.6  Voting. At each meeting of shareholders, every shareholder will be entitled
     ------                                                                     
to vote in person or by proxy and, unless modified by a cumulative voting
provision contained in the Corporation's Certificate of Incorporation, will have
one vote for each share standing registered in his name at the closing of the
transfer books for such meeting, or the record date fixed for such meeting by
the Board, as the case may be, or standing registered in his name at the time of
such meeting if neither a date for the closing of the transfer books nor a
record date for such meeting has been fixed by the Board. The voting at all
meetings of shareholders may be oral, but any qualified voter may demand a vote
by written ballot, whereupon such vote will be taken by written ballot stating
the name of the shareholder, the number of shares voted and, if such ballot be
cast by proxy, the name of such proxy.

3.7  Proxies. Any shareholder entitled to vote may vote by proxy. The
     -------                                                         
appointment of a proxy will be in writing signed by the shareholder but will
require no other attestation. Each proxy statement will be filed with the
secretary of the Corporation at or before the meeting. In no case will a proxy
be appointed for a period of over seven (7) years. If any shareholder appoints
two (2) or more persons to act as proxies and if the instrument does not
otherwise provide, a majority of such persons present at the meeting (or if only
one is present, then that one) may exercise all of the powers conferred by such
instrument on all of the persons so appointed, and if such proxies are equally
divided as to the right and manner of voting in any particular case, the vote
will be divided among the proxies.  Any person holding shares in a
representative or fiduciary capacity which he may represent in person may
represent the same by proxy and confer general or 

                                       2
<PAGE>
 
discretionary power on such proxy. The authority of a proxy not coupled with an
interest may be terminated at will. Unless otherwise provided in the
appointment, the proxy's authority will cease three (3) years after the
appointment. The termination of a proxy's authority by act of the shareholder
will, subject to the time limitations herein set forth, be ineffective until
written notice of the termination has been given to the secretary of the
Corporation. Unless otherwise provided therein, an appointment filed with the
secretary will have the effect of revoking all proxy appointments of prior date.
A proxy's authority will not be revoked by the death or incapacity of the
shareholder, unless before the vote is cast or the authority is exercised
written notice of such death or incapacity is given to the secretary of the
Corporation.

3.8  Officers of Shareholders' Meetings. The president, if present, will preside
     ----------------------------------

meeting, regardless of how call was made or notice given, will be valid as
though transacted at a meeting duly held by regular call and notice if a quorum
is present and if before or after the meeting each of the shareholders entitled
to vote and not present in person or by proxy signs a written waiver of notice.
All such waivers of notice will be filed with the secretary and made a part of
the records of the meeting.

      -------------------                                                      
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Corporation) by reason of the fact that such person is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses, including attorneys' fees, judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding if such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent, will not, of
itself, create a presumption that such person did not act in good faith and in a
manner which such person reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that the conduct was unlawful.

14.2  Actions by Corporation. The Corporation will have the power to indemnify
      ----------------------                                                  
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in the Corporation's favor by reason of the
fact that such person is or was a director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses, including attorney's fees
actually and reasonably incurred by such person in connection with the defense
or settlement of such action 

                                       12
<PAGE>
 
or suit if such person acted in good faith and in a manner reasonably believed
to be in or not opposed to the best interests of the Corporation; except that no
indemnification will be made in respect of any claim, issue or matter as to
which such person is adjudged to be liable for negligence or misconduct in the
performance of a duty to the Corporation, unless and only to the extent that the
court in which such action or suit was brought determines upon application that,
despite adjudication of liability but in view of all the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which such court deems proper.

14.3  Right to Indemnification. To the extent that any present or former
      ------------------------                                          
director, officer, employee or person who is or was serving at the request of
the Corporation as a director, officer or employee of another corporation,
partnership, joint venture, trust or other enterprise, or any agent of the
Corporation or any person who is or was serving at the request of the
Corporation as an agent of another corporation, partnership, joint venture,
trust or other enterprise, has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in Sections 14.1 or 14.2,
or in defense of any claim, issue or matter therein, such person will be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred in connection therewith.

14.4  Authorization of Indemnification. Any indemnification under Sections 14.1
      --------------------------------                                         
or 14.2, unless ordered by a court, will be made by the Corporation only as
authorized in the specific case on a determination that indemnification of the
director, officer, employee or agent is proper in the circumstances because such
person has met the applicable standard of conduct set forth in Sections 14.1 or
14.2. Such determination will be made by the Board by (a) a majority vote of a
quorum consisting of directors who were not parties to such action, suit or
proceeding, or (b) if such quorum is not obtainable or even if it is obtainable
and a quorum of disinterested directors so directs, by independent legal counsel
in a written opinion, or (c) by the shareholders.

14.5  Advance Indemnification. Expenses incurred by an officer or director in
     -----------------------                                                
defending a civil or criminal action, suit or proceeding may be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding on receipt of an undertaking by or on behalf of such director or
officer to repay such amount unless it is ultimately determined that such person
is entitled to be indemnified by the Corporation as authorized by the provisions
of this Article. Such expenses incurred by other employees and agents may be so
paid on such terms and conditions, if any, as the Board deems appropriate.

14.6  Nonexclusive Indemnification. The indemnification and advancement of
     ----------------------------                                        
expenses provided by this Article 14 will not be 

                                       13
<PAGE>
 
deemed exclusive of any other rights to which those seeking indemnification
might be entitled under any bylaw, agreement, vote of shareholders or
disinterested directors or otherwise, both as to action in an official capacity
and as to action in another capacity while holding such office, and will
continue as to a person who has ceased to be a director, officer, employee or
agent and inure to the benefit of the heirs, executors and administrators of
such person.

14.7  Insurance. The Corporation will have the power to purchase and maintain
      ---------                                                              
insurance on behalf of any person who is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
and incurred by such person in any such capacity, or arising out of such
person's status as such, whether or not the Corporation would have the power to
indemnify such person against such liability under the provisions of this
Article 14.

14.8  Constituent Corporation. For the purposes of this Article, references to
      -----------------------

consolidation or merger as well as the resulting or surviving corporation so
that any person who is or was a director, officer, employee or agent of such a
constituent corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise will stand in
the same position under the provisions of this Article 14 with respect to the
resulting or surviving corporation as such person would have with respect to

SHARE CAPITAL

     2.   Subject to the provisions of the Act and without prejudice to any
rights attached to any existing shares, any share 
<PAGE>
 
may be issued with such rights or restrictions as the company may by ordinary
resolution determine.

     3.   Subject to the provisions of the Act, shares may be issued which are
to be redeemed or are to be liable to be redeemed at the option of the company
or the holder on such terms and in such manner as may be provided by the
articles.

     4.   The company may exercise the powers of paying commissions conferred by
the Act.  Subject to the provisions of the Act, any such commission may be
satisfied by the payment of cash or by the allotment of fully or partly paid
shares or partly in one way and partly in the other.

     5.   Except as required by law, no person shall be recognized by the
company as holding any share upon any trust and (except as otherwise provided by
the articles or by law) the company shall not be bound by or recognize any
interest in any share except an absolute right to the entirety thereof in the
holder.

SHARE CERTIFICATES

     6.   Every member, upon becoming the holder of any shares, shall be
entitled without payment to one certificate for all the shares of each class
held by him (and, upon transferring a part of his holding of shares of any
class, to a certificate for the balance of such holding) or several certificates
each for one or more of his shares upon payment for every certificate after the
first of such reasonable sum as the directors may determine.  Every certificate
shall be sealed with the seal and shall specify the number, class and
distinguishing number (if any) of the shares to which it relates and the amount
or respective amounts paid up thereon.  The company shall not be bound to issue
more than one certificate for shares held jointly by several persons and
delivery of a certificate to one joint holder shall be a sufficient delivery to
all of them.

     7.   If a share certificate is defaced, worn-out, lost or destroyed, it may
be renewed on such terms (if any) as to evidence and indemnify and payment of
the expenses reasonably incurred by the company in investigating evidence as the
directors may determine but otherwise free of charge, and (in the case of
defacement or wearing-out) on delivery op of the old certificate.

LIEN

     8.   The company shall have a first and paramount lien on every share (not
being a fully paid share) for all moneys (whether presently payable or not)
payable at a fixed time or called in respect of that share.  The directors may
at any time declare any share to be wholly or in part exempt from the provisions
of this 

                                       2
<PAGE>
 
regulation. The company's lien on a share shall extend to any amount payable in
respect of it.

     9.   The company may sell in such manner as the directors determine any
shares on which the company has a lien if a sum in respect of which the lien
exists is presently payable and is not paid within fourteen clear days after
notice has been given to the holder of the share or to the person entitled to it
in consequence of the death or bankruptcy of the holder, demanding payment and
stating that if the notice is not complied with the shares may be sold.

     10.  To give effect to a sale the directors may authorize some person to
execute an instrument of transfer of the shares sold to, or in accordance with
the directions of, the purchaser.  The title of the transferee to the shares
shall not be affected by any irregularity in or invalidity of the proceedings in
reference to the sale.

     11.  The net proceeds of the sale, after payment of the costs, shall be
applied in payment of so much of the sum for which the lien exists as is
presently payable, and any residue shall (upon surrender to the company for
cancellation of the certificate for the shares sold and subject to a like lien
for any moneys not presently payable as existed upon the shares before the sale)
be paid to the person entitled to the shares at the date of the sale.

CALLS ON SHARES AND FORFEITURE

     12.  Subject to the terms of allotment, the directors may make calls upon
the members in respect of any moneys unpaid on their shares (whether in respect
of nominal value or premium) and each member shall (subject to receiving at
least fourteen clear days' notice specifying when and where payment is to be
made) pay to the company as required by the notice the amount called on his
shares. A call may be required to be paid by installments.  A call may, before
receipt by the company of any sum due thereunder, be revoked in whole or part
and payment of a call may be postponed in whole or part.  A person upon whom a
call is made shall remain liable for calls made upon his notwithstanding the
subsequent transfer of the shares in respect whereof the call was made.

     13.  A call shall be deemed to have been made at the time when the
resolution of the directors authorizing the call was passed.

     14.  The joint holder of a share shall be jointly and severally liable to
pay all calls in respect thereof.

     15.  If a call remains unpaid after it has become due and payable the
person from whom it is due and payable shall pay interest on the amount unpaid
from the day it became due and payable until it is paid at the rate fixed by the
terms of 

                                       3
<PAGE>
 
allotment of the share or in the notice of the call, or if no rate is fixed, at
the appropriate rate (as defined by the Act) but the directors may waive payment
of the interest wholly or in part.

     16.  An amount payable in respect of a share on allotment or at any fixed
date, whether in respect of nominal value or premium or as an installment of a
call, shall be deemed to be a call and if it is not paid the provisions of the
articles shall apply as if that amount had become due and payable by virtue of a
call.

     17.  Subject to the terms of allotment, the directors may make arrangements
on the issue of shares for a difference between the holders in the amounts and
times of payment of calls on their shares.

     18.  If a call remains unpaid after it has become due and payable the
directors may give to the person from whom it is due not less than fourteen
clear days' notice requiring payment of the amount unpaid together with any
interest which may have accrued. The notice shall name the place where payment
is to be made and shall state that if the notice is not complied with the shares
in respect of which the call was made will be liable to be forfeited.

     19.  If the notice is not complied with any share in respect of which it
was given may, before the payment required by the notice has been made, be
forfeited by a resolution of the directors and the forfeiture shall include all
dividends or other moneys payable in respect of the forfeited shares and not
paid before the forfeiture.

     20.  Subject to the provisions of the Act, a forfeited share may be sold,
re-allotted or otherwise disposed of on such terms and in such manner as the
directors determine either to the person who was before the forfeiture the
holder or to any other person and at any time before sale, re-allotment or other
disposition, the forfeiture may be cancelled on such terms as the directors
think fit.  Where for the purposes of its disposal a forfeited share is to be
transferred to any person the directors may authorize some person to execute an
instrument of transfer of the share to that person.

     21.  A person any of whose shares have been forfeited shall cease to be a
member in respect of them and shall surrender to the company for cancellation
the certificate for the shares forfeited but shall remain liable to the company
for all moneys which at the date of forfeiture were presently payable by him to
the company in respect of those shares with interest at the rate at which
interest was payable on those moneys before the forfeiture or, if no interest
was so payable, at the appropriate rate (as defined in the Act) from the date of
forfeiture until payment but the directors may waive payment wholly or in part
or enforce payment without any 

                                       4
<PAGE>
 
allowance for the value of the shares at the time of forfeiture or for any
consideration received on their disposal.

     22.  A statutory declaration by a director of the secretary that a share
has been forfeited on a specified date shall be conclusive evidence of the facts
stated in it as against all persons claiming to be entitled to the share and the
declaration shall (subject to the execution of an instrument of transfer if
necessary) constitute a good title to the share and the person to whom the share
is disposed of shall not be bound to see to the application of the
consideration, if any, nor shall his title to the share be effected by any
irregularity in or invalidity of the proceedings in reference to the forfeiture
or disposal of the share.

TRANSFER OF SHARES

     23.  The instrument of transfer of a share may be in any usual form or in
any other form which the directors may approve and shall be executed by or on
behalf of the transferor and, unless the share is fully paid, by or on behalf of
the transferee.

     24.  The directors may refuse to register the transfer of a share which is
not fully paid to a person of whom they do not approve and they may refuse to
register the transfer of a share on which the company has a lien.  They may also
refuse to register a transfer unless:

          (a) it is lodged at the office or at such other place as the directors
     may appoint and is accompanied by the certificate for the shares to which
     it relates and such other evidence as the directors may reasonably require
     to show the right of the transferor to make the transfer;

          (b) it is in respect of only one class of shares; and

          (c) it is in favor of not more than four transferees.

     25.  If the directors refuse to register a transfer of a share, they shall
within two months after the date on which the transfer was lodged with the
company send to the transferee notice of the refusal.

     26.  The registration of transfers of shares or of transfers of any class
of shares may be suspended at such times and for such periods (not exceeding
thirty days in any year) as the directors may determine.

     27.  No fee shall be charged for the registration of any instrument of
transfer or other document relating to or affecting the title to any share.

                                       5
<PAGE>
 
     28.  The company shall be entitled to retain any instrument of transfer
which is registered, but any instrument of transfer which the directors refuse
to register shall be returned to the person lodging it when notice of the
refusal is given.

TRANSMISSION OF SHARES

     29.  If a member dies the survivor or survivors where he was a joint
holder, and his personal representatives where he was a sole holder or the only
survivor of joint holders, shall be the only persons recognized by the company
as having any title to his interest; but nothing herein contained shall release
the estate of a deceased member from any liability in respect of any share which
had been jointly held by him.

     30.  A person becoming entitled to a share in consequence of the death or
bankruptcy of a member may, upon such evidence being produced as the directors
may properly require, elect either to become the holder of the share or to have
some person nominated by him registered as the transferee.  If he elects to
become the holder he shall give notice to the company to that effect.  If he
elects to have another person registered he shall execute an instrument of
transfer of the share to that person.  All the articles relating to the transfer
of shares shall apply to the notice or instrument of transfer as if it were an
instrument of transfer executed by the member and the death or bankruptcy of the
member had not occurred.

     31.  A person becoming entitled to a share in consequence of the death or
bankruptcy of a member shall have the rights to which he would be entitled if he
were the holder of the share, except that he shall not, before being registered
as the holder of the share, be entitled in respect of it to attend or vote at
any meeting of the company or at any separate meeting of the holders of any
class of shares in the company.

ALTERATION OF SHARE CAPITAL

     32.  The company may by ordinary resolution:

          (a) increase its share capital by new shares of such amount as the
     resolution prescribes;

          (b) consolidate and divide all or any of its share capital into shares
     of larger amount to an its existing shares;

          (c) subject to the provisions of the Act, subdivide its shares, or any
     of them, into shares of smaller amount and the resolution may determine
     that, as between the shares resulting from the subdivision, any of them may
     have any preference or advantage as compared with the others; and

                                       6
<PAGE>
 
          (d)  cancel shares which, at the date of the passing of the
     resolution, have not been taken or agreed to be taken by any person and
     diminish the amount of its share capital by the amount of the shares so
     cancelled.

     33.  Whenever as a result of a consolidation of shares any members would
become entitled to fractions of a share, the directors may, on behalf of those
members, sell the shares representing the fractions for the best price
reasonably obtainable to any person (including, subject to the provisions of the
Act, the company) and distribute the net proceeds of sale in due proportion
among those members, and the directors may authorize some person to execute an
instrument of transfer of the shares to, or in accordance with the direction of,
the purchaser.  The transferee shall not be bound to see to the application of
the purchase money nor shall his title to the shares to the shares be affected
by any irregularity in or invalidity of the proceedings in reference to the
sale.

     34.  Subject to the provisions of the Act, the company may by special
resolution reduce its share capital, any capital redemption serve and any share
premium account in any way.

PURCHASE OF OWN SHARES

     35.  Subject to the provisions of the Act, the company may purchase its own
shares (including any redeemable shares) and, if it is a private company, make a
payment in respect of the redemption or purchase of its own shares otherwise
than out of distributable profits of the company or the proceeds of a fresh
issue of shares.

GENERAL MEETINGS

     36.  All general meetings other than annual general meetings shall be
called extraordinary general meetings.

     37.  The directors may call general meeting and, on the requisition of
members pursuant to the provisions of the Act, shall forthwith proceed to
convene an extraordinary general meeting for a date not later than eight weeks
after receipt of the requisition. If there are not within the United Kingdom
sufficient directors to call a general meeting, any director or any member of
the company may call a general meeting.

NOTICE OF GENERAL MEETINGS

     38.  An annual general meeting and an extraordinary general meeting called
for the passing of a special resolution or a resolution appointing a person as a
director shall be called by at least twenty-one clear days' notice.  All other
extraordinary general meetings shall be called by at least fourteen clear days'

                                       7
<PAGE>
 
notice but a general meeting may be called by shorter notice if it is so agreed:

          (a)  in the case of an annual general meeting, by all the members
     entitled to attend and vote thereat; and

          (b)  in the case of any other meeting by a majority in number of the
     members having a right to attend and vote being a majority together holding
     not less than ninety-five percent, in nominal value of the shares giving
     that right

The notice shall specify the time and place of the meeting and the general
nature of the business to be transacted and, in the case of an annual general
meeting, shall specify the meeting as such.

     Subject to the provisions of the articles and to any restrictions imposed
on any share, the notice shall be given to all the members, to all persons
entitled to a share in consequence of the death or bankruptcy of a member and to
the directors and auditors.

     39.  The accidental omission to give notice of a meeting to, or the non-
receipt of notice of a meeting by, any person entitled to receive notice shall
not invalidate the proceedings at that meeting.

PROCEEDINGS AT GENERAL MEETINGS

     40.  No business shall be transacted at any meeting unless a quorum is
present.  Two persons entitled to vote upon the business to be transacted, each
being a member or a proxy for a member or a duly authorized representative of a
corporation, shall be a quorum.

     41.  If such a quorum is not present within half an hour from the time
appointed for the meeting, or if during a meeting such a quorum ceases to be
present, the meeting shall stand adjourned to the same day in the next week at
the same time and place or to such time and place as the directors may
determine.

     42.  The chairman, if any of the board of directors or in his absence some
other director nominated by the directors shall preside as chairman of the
meeting, but if neither the chairman nor such other director (if any) be present
within fifteen minutes after the time appointed for holding the meeting and
willing to act, the directors present shall elect one of their number to be
chairman and, if there is only one director present and willing to act, he shall
be chairman.

     43.  If no director is willing to act as chairman, or if no director is
present within fifteen minutes after the time appointed for holding the meeting,
the members present and entitled to vote shall choose one of their number to be
chairman.

                                       8
<PAGE>
 
     44.  A director shall, notwithstanding that he is not a member, be entitled
to attend and speak at any general meeting and at any separate meeting of the
holders of any class of shares in the company.

     45.  The chairman may, with the consent of a meeting at which a quorum is
present (and shall if so directed by the meeting), adjourn the meeting from time
to time and from place to place, but no business shall be transacted at an
adjourned meeting other than business which might properly have been transacted
at the meeting had the adjournment not taken place.  When a meeting is adjourned
for fourteen days or more, at least seven clear days' notice shall be given
specifying the time and place of the adjourned meeting and the general nature of
the business to be transacted.  Otherwise it shall not be necessary to give any
such notice.

     46.  A resolution put to the vote of a meeting shall be decided on a show
of hands unless before, or on the declaration of the result of, the show of
hands a poll is duly demanded.  Subject to the provisions of the Act, a poll may
be demanded:

          (a)  by the chairman; or

          (b)  by at least two members having the right to vote at the meeting;
     or

          (c)  by a member or members representing not less than one-tenth of
     the total voting rights of all the members having the right to vote at the
     meeting; or

          (d)  by a member or members holding shares conferring a right to vote
     at the meeting being shares on which an aggregate sum has been paid up
     equal to not less than one-tenth of the total sum paid up on all the shares
     conferring that right;

and a demand by a person as proxy for a member shall be the same as a demand by
the member.

     47.  Unless a poll is duly demanded a declaration by the chairman that a
resolution has been carried or carried unanimously, or by a particular majority,
or lost, or not earned by a particular majority and an entry to that effect in
the minutes of the meeting shall be conclusive evidence of the fact without
proof of the number of proportion of the votes recorded in favor of or against
the resolution.

     48.  The demand for a poll may, before the poll is taken, be withdrawn but
only with the consent of the chairman and a demand so withdrawn shall not be
taken to have invalidated the result of a show of hands declared before the
demand was made.

                                       9
<PAGE>
 
     49.  A poll shall be taken as the chairman directs and he may appoint
scrutineers (who need not be members) and fix a time and place for declaring the
result of the poll.  The result of the poll shall be deemed to be the resolution
of the meeting at which the poll was demanded.

     50.  In the case of an equality of votes, whether on a show of hands or on
a poll, the chairman shall be entitled to a casting vote in addition to any
other vote he may have.

     51.  A poll demanded on the election of a chairman or on a question of
adjournment shall be taken forthwith.  A poll demanded on any other question
shall be taken either forthwith or at such time and place as the chairman
directs not being more than thirty days after the poll is demanded.  The demand
for a poll shall not prevent the continuance of a meeting for the transaction of
any business other than the question on which the poll was demanded. If a poll
is demanded before the declaration of the result of a show of hands and the
demand is duly withdrawn, the meeting shall continue as if the demand had not
been made.

     52.  No notice need be given of a poll not taken forthwith if the time and
place at which it is to be taken are announced at the meeting at which it is
demanded.  In any other case at least seven clear days' notice shall be given
specifying the time and place at which the poll is to be taken.

     53.  A resolution in writing executed by or on behalf of each member who
would have been entitled to vote upon it if it had been proposed at a general
meeting at which he was present shall be as effectual as if it had been passed
at a general meeting duly convened and held and may consist of several
instruments in the like form each executed by or on behalf of one or more
members.

VOTES OF MEMBERS

     54.  Subject to any rights or restrictions attached to any shares, on a
show of hands every member who (being an individual) is present in person or
(being a corporation) is present by a duly authorized representative, not being
himself a member entitled to vote, shall have one vote and on a poll every
member shall have one vote for every share of which he is the holder.

     55.  In the case of joint holders the vote of the senior who tenders a
vote, whether in person or by proxy, shall be accepted to the exclusion of the
votes of the other joint holders; and seniority shall be determined by the order
in which the names of the holders stand in the register of members.

     56.  A member in respect of whom an order has been made by any court having
jurisdiction (whether in the United Kingdom or elsewhere) in matters concerning
mental disorder may vote, whether 

                                      10
<PAGE>
 
on a show of hands or on a poll, by his receiver, curator bonis or other person
authorized in that behalf appointed by that court, and any such receiver,
curator bonis or other person may, on a poll, vote by proxy. Evidence to the
satisfaction of the directors of the authority of the person claiming to
exercise the right to vote shall be deposited at the office, or at such other
place as is specified in accordance with the articles for the deposit of
instruments of proxy, not less than 48 hours before the time appointed for
holding the meeting or adjourned meeting at which the right to vote is to be
exercised and in default the right to vote shall not be exercisable.

     57.  No member shall vote at any general meeting or at any separate meeting
of the holders of any class of shares in the company, either in person or by
proxy, in respect of any share held by him unless all moneys presently payable
by him in respect of that share have been paid.

     58.  No objection shall be raised to the qualification of any voter except
at the meeting or adjourned meeting at which the vote objected to is tendered,
and every vote not disallowed at the meeting shall be valid.  Any objection made
in due time shall be referred to the chairman whose decision shall be final and
conclusive.

     59.  On a poll votes may be given either personally or by proxy.  A member
may appoint more than one proxy to attend on the same occasion.

     60.  An instrument appointing a proxy shall be in writing, executed by or
on behalf of the appointor and shall be in the following form (or in a form as
near thereto as circumstances allow or in any other form which is usual or which
the directors may approve):

                                  PLC/Limited

I/We, ______________, of ___________________ being a member/members of the
above-named company, hereby appoint ______________ of ________________, or
failing him, _____________ of _________________, as my/our proxy to vote in

United Kingdom. Questions arising at a meeting shall be decided by a majority of
votes.  In the case of an equality of votes, the chairman shall have a second or
casting vote.  A director who is also an alternate director shall be entitled in
the absence of his appointor to a separate vote on behalf of his appointor in
addition to his ___ vote.

     89.  The quorum for the transaction of the business of the directors may be
fixed by the directors and unless so fixed at any other number shall be two

director may act only for the purpose of filling vacancies or of calling a
general meeting.

     91.  The directors may appoint one of their number to be the chairman of
the board of directors and may at any time remove him from that office.  Unless
he is unwilling to do so, the director so appointed shall preside at every
meeting of directors at which he is present.  But if there is no director
holding that office, or if the director holding it is unwilling to preside or is
not present within five minutes after the time appointed for the meeting, the
directors present may appoint one of their number to be chairman of the meeting.

     92.  All acts done by a meeting of directors, or of a committee of
directors, or by a person acting as a director shall, notwithstanding that it be
afterwards discovered that there was a defect in the appointment of any director
or that any of them were

<PAGE>
 
disqualified from holding office, or had vacated office, or were not entitled to
vote, be as valid as if every such person had been duly appointed and was
qualified and had continued to be a director and had been entitled to vote.

     93.  A resolution in writing signed by all the directors entitled to
receive notice of a meeting of directors or of a committee of directors shall be
as valid and effectual as if it had been passed at a meeting of directors or (as
the case may be) a committee of directors duly convened and held and may consist
of several documents in the like form each signed by one or more directors; but
a resolution signed by an alternate director need not also be signed by his
appointor and, if it is signed by a director who has appointed an alternate
director, it need not be signed by the alternate director in that capacity.

     94.  Save as otherwise provided by the articles, a director shall not vote
at a meeting of directors or of a committee of directors on any resolution
concerning a matter in which he has, directly or indirectly, an interest or duty
which is material and which conflicts or may conflict with the interests of the
company unless his interest or duty arises only because the case falls within
one or more of the following paragraphs:

          (a)  the resolution relates to the giving to him of a guarantee,
     security, or indemnity in respect of money lent to, or an obligation
     incurred by him for the benefit of, the company or any of its subsidiaries;

          (b)  the resolution relates to the giving to a third party of a
     guarantee, security, or indemnity in respect of an obligation of the
     company or any of its subsidiaries for which the director has assumed
     responsibility in whole or part and whether alone or jointly with others
     under a guarantee or indemnity or by the giving of security;

          (c)  his interest arises by virtue of subscribing or agreeing to
     subscribe for any shares, debentures or other securities of the company or
     any of its subsidiaries, or by virtue of his being, or intending to become,
     a participant in the underwriting or sub-underwriting of an offer of any
     such shares, debentures, or other securities by the company or any of its
     subsidiaries for subscription, purchase or exchange;

          (d)  the resolution relates in any way to a retirement benefits scheme
     which has been approved, or is conditional upon approval, by the Board of
     Inland Revenue for taxation purposes.

     For the purposes of this regulation, an interest of a person who is, for
     any purpose of the Act (excluding any statutory modification thereof not in
     force when the regulation becomes 

                                      19
<PAGE>
 
     binding on the company), connected with a director shall be treated as an
     interest of the director and, in relation to an alternate director, an
     interest of his appointor shall be treated as an interest of the alternate
     director without prejudice to any interest which the alternate director has
     otherwise.

     95.  A director shall not be counted in the quorum present at a meeting in
relation to a resolution on which he is not entitled to vote.

     96.  The company may by ordinary resolution suspend or relax to any extent,
either generally or in respect of any particular matter, any provision of the
articles prohibiting a director from voting at a meeting of directors or of a
committee of directors.

     97.  Where proposals are under consideration concerning the appointment of
two or more directors to offices or employments with the company or any body
corporate in which the company is interested the proposals may be divided and
considered in relation to each director separately and (provided he is not for
another reason precluded from voting) each of the directors concerned shall be
entitled to vote and be counted in the quorum in respect of each resolution
except that concerning his own appointment.

     98.  If a question arises at a meeting of directors or of a committee of
directors as to the right of a director to vote, the question may, before the
conclusion of the meeting, be referred to the chairman of the meeting and his
ruling in relation to any director other than himself shall be final and
conclusive.

SECRETARY

     99.  Subject to the provisions of the Act, the secretary shall be appointed
by the directors for such term, at such remuneration and upon such conditions as
they may think fit; and any secretary so appointed may be removed by them.

MINUTES

     100. The directors shall cause minutes to be made in books kept for the
purpose:

          (a)  of all appointments of officers made by the directors; and

          (b)  of all proceedings at meetings of the company, of the holders of
     any __________, of shares in the company, and of the directors, and of
     committees of directors, including the names of the directors present at
     each such meeting.

THE SEAL

     101. The seal shall only be used by the authority of the directors or of a
committee of directors authorized by the directors.  The directors may determine
who shall sign any instrument to which the seal is affixed and unless otherwise
so determined it shall be signed by a director and by the secretary or by a
second director.

DIVIDENDS

     102. Subject to the provisions of the Act, the company may by ordinary
resolution declare dividends in accordance with the respective rights of the
members, but no dividend shall exceed the amount recommended by the directors.

     103. Subject to the provisions of the Act, the directors may pay interim
dividends if it appears to them that they are justified by the profits of the
company available for distribution.  If the share capital is divided into
different classes, the directors may pay interim dividends on shares which
confer deferred or non-preferred rights with regard to dividend as well as on
shares which confer preferential rights with regard to dividend, but no interim
dividend shall be paid on shares carrying deferred or non-preferred rights if,
at the time of payment, any preferential dividends is in arrears.  The directors
may also pay at intervals settled by them any dividend payable at a fixed rate
if it appears to them that the profits available for distribution justify the
payment.  Provided the directors act in good faith they shall not incur any
liability to the holders of shares conferring preferred rights for any loss they
may suffer by the lawful payment of an interim dividend on any shares having
deferred or non-preferred rights.

     104. Except as otherwise provided by the rights attached to shares, all
dividends shall be declared and paid according to the amounts paid up on the
shares on which the dividend is paid.  All dividends shall be apportioned and
paid proportionately to the amounts paid up on the shares during any portion or
portions of the period in respect of which the dividend is paid; but, if any
share is issued on terms providing that it shall rank for dividend as from a
particular date, that share shall rank for dividend accordingly.

     105. A general meeting declaring a dividend may, upon the recommendation of
the directors, direct that it shall be satisfied wholly or partly by the
distribution of assets and, where any difficulty arises in regard to the
distribution the directors may settle the same and in particular may issue
fractional certificates and fix the value for distribution of any assets and may
determine that cash shall be paid to any member upon the footing of the value 

                                      21
<PAGE>
 
so fixed in order to adjust the rights of members and may vest any assets in
trustees.

     106. Any dividend or other moneys payable in respect of a share may be paid
by cheque sent by post to the registered address of the person entitled or, if
two or more persons are the holders of the share or are jointly entitled to it
by reason of the death or bankruptcy of the holder, to the registered address of
that one of those persons who is first named in the register of members or to
such person and to such address as the person or persons entitled may in writing
direct.  Every cheque shall be made payable to the order of the person or
persons entitled or to such other person as the person or persons entitled may
in writing direct and payment of the cheque shall be a good discharge to the
company. Any joint holder or other person jointly entitled to a share as
aforesaid may give receipts for any dividend or other moneys payable in respect
of the share.

     107. No dividend or other moneys payable in respect of a share shall bear
interest against the company unless otherwise provided by the rights attached to
the share.

     108. Any dividend which has remained unclaimed for twelve years from the
date when it became due for payment shall, if the directors so resolve, be
forfeited and cease to remain owing by the company.

ACCOUNTS

     109. No member shall (as such) have any right of inspecting any accounting
records or other book or document of the company except as conferred by statute
or authorized by the directors or by ordinary resolution of the company.

CAPITALIZATION OF PROFITS

     110. The directors may with the authority of an ordinary resolution of the
company:

          (a)  subject as hereinafter provided, resolve to capitalize any
     undivided profits of the company not required for paying any preferential
     dividend (whether or not they are available for distribution) or any sum
     standing to the credit of the company's share premium account or capital
     redemption reserve;

          (b)  appropriate the sum resolved to be capitalized to the members who
     would have been entitled to it if it were distributed by way of dividend
     and in the same proportions and apply such sum on their behalf either in or
     towards paying up the amounts, if any, for the time being unpaid on any
     shares held by them respectively, or in paying up in full unissued 

                                      22
<PAGE>
 
     shares or debentures of the company of a nominal amount equal to that sum,
     and allot the shares or debentures credited as fully paid to those members,
     or as they may direct, in those proportions, or partly in one way and
     partly in the other; but the share premium account, the capital redemption
     reserve, and any profits which are not available for distribution may, for
     the purposes of this regulation, only be applied in paying up unissued
     shares to be allotted to members credited as fully paid;

          (c)  make such provision by the issue of fractional certificates or by
     payment in cash or otherwise as they determine in the case of shares or
     debentures becoming distributable under this regulation in fractions; and

          (d)  authorize any person to enter on behalf of all the members
     concerned into an agreement with the company providing for the allotment to
     them respectively, credited as fully paid, of any shares or debentures to
     which they are entitled upon such capitalization, any agreement made under
     such authority being binding on all such members.

NOTICES

     111. Any notice to be given to or by any person pursuant to the articles
shall be in writing except that a notice calling a meeting of the directors need
not be in writing.

     112. The company may give any notice to a member either personally or by
sending it by post in a prepaid envelope addressed to the member at his
registered address or by leaving it at that address.  In the case of joint
holders of a share, all notices shall be given to the joint holder whose name
stands first in the register of members in respect of the joint holding and
notice so given shall be sufficient notice to all the joint holders.  A member
whose registered address is not within the United Kingdom and who gives to the
company an address within the United Kingdom at which notices may be given to
him shall be entitled to have notices given to him at that address, but
otherwise no such member shall be entitled to receive any notice from the
company.

     113. A member present, either in person or by proxy, at any meeting of the
company or of the holders of any class of shares in the company shall be deemed
to have received notice of the meeting and, where requisite, of the purposes for
which it was called.

notice in respect of that share which, before his name is entered in the
register of members, has been duly given to a person from whom he derives his
title.

     115. Proof that an envelope containing a notice was properly addressed,
prepaid and posted shall be conclusive evidence that the notice was given.  A
notice shall be deemed to be given at the expiration of 48 hours after the
envelope containing it was posted.

     116. A notice may be given by the company to the persons entitled to a
share in consequence of the death or bankruptcy of a member by sending or
delivering it, in any manner authorized by the articles for the giving of notice
to a member, addressed to them by name, or by the title of representatives of
the deceased, or trustee of the bankrupt or by any like description at the
address, if any, within the united Kingdom supplied for that purpose by the
persons claiming to be so entitled.  Until such an address has been supplied, a
notice may be given in any manner in which it might have been given if the death
or bankruptcy had not occurred.

WINDING UP

     117. If the company is wound up, the liquidator may, with the sanction of
an extraordinary resolution of the company and any other sanction required by
the Act, divide among the members in specie the whole or any part of the assets
of the company and may, for that purpose, value any assets and determine how the
division shall be carried out as between the members or different classes of
members.  The liquidator may, with the like sanction, vest the whole or any part
of the assets in trustees upon such trusts for the benefit of the members as he
with the like sanction determines, but no member shall be compelled to accept
any assets upon which there is a liability.

INDEMNITY

     118. Subject to the provisions of the Act but without prejudice to any
indemnity to which a director may otherwise be entitled, every director or other
officer or auditor of the company shall be indemnified out of the assets of the
company against any liability incurred by him in defending any proceedings,
whether civil or criminal, in which judgment is given in his favour or in which
he is ______________ or in connection with any application in which relief is
granted to him by the court from liability for negligence, default, breach of
duty or breach of trust in relation to the affairs of the company.

company standing to the credit of the company's reserve fund and/or to the
credit of the profit and loss account and accordingly that such sum be
distributed as a bonus free of income tax or otherwise amongst the holders of
those shares who would be entitled to participate in that sum if it were being
distributed as a dividend in proportion to the shares held by them respectively

ordinary shares in like proportion. When such resolution has been passed the
directors may allot and issue such unissued ordinary shares credited as fully
paid up to the holders of the said shares in satisfaction of the said bonus and
as nearly as may be in proportion to the said shares held by them respectively.
Where any difficulty arises in regard to the distribution they may settle the
same as they think expedient and in particular may issue fractional certificates
and may fix the value for distribution of such specific assets or any part
thereof and may determine that cash payments shall be made to any members upon
the footing of the value so fixed in order to adjust the rights of all parties
and may vest any such specific assets in trustees upon such trusts for the
persons entitled to the dividend as may seem expedient to the directors. Where
requisite a proper contract shall be filed in accordance with the Companies
(Queensland) Code for the time being and the directors may appoint any person to
sign such contract on behalf of the persons entitled to the dividend and such
appointments shall be effective.

       representative of any shareholder, unless and until, the rights of pre-
       emption conferred in this constitution have been exhausted.

4.3    TRANSFER NOTICE
4.3.1  Except where the transfer is made pursuant to clauses 4.10 (transfer to
       relatives) and 4.11 (transfer approved by all 

                                       2

       shareholders), the person proposing to sell or transfer any shares
       ("proposing transferor") must give notice in writing (a "transfer
       notice") to the company that the proposing transferor desires to transfer
       the shares. The transfer notice must specify the sum which the proposing
       transferor considers to be the value of the shares and must (subject to
       this clause) make the company the proposing transfer's agent for the sale
       of the shares to any shareholder at the price specified or, at the option
       of the purchasing shareholder (as defined in clause 4.4), at the fair
       value to be fixed in accordance with clause 4.5.

4.3.2  If a transfer notice includes several shares it will not operate as if it
       were a separate transfer notice in respect of each of the shares and the
       proposing transferor will be under no obligation to sell or transfer part
       only of the shares specified in the transfer notice. The transfer notice
       is not revocable without the sanction of the board in writing, other than
       as provided in clause 4.6. If no price is specified by-a proposing
       transferor the proposing transferor will be deemed to want to sell or
       transfer the shares at their fair value.

4.4    COMPANY FINDING BUYER
       If the company, within 3 calendar months after being served with a
       transfer notice, finds a shareholder or shareholders willing to purchase
       all the shares ("purchasing shareholder") and gives notice of that to the
       proposing transferor, the proposing transferor will, subject to clause
       4.6 (right to revoke), be bound upon payment of the sum specified in the
       transfer notice or, as the case may be, at the fair value determined
       under clause 4.5 (subject to any lien which the company may have under
       the constitution to make a deduction in respect of that lien), to
       transfer the shares to the purchasing shareholder.

4.5    ARBITRATION OF FAIR VALUE
4.5.1  If any difference arises between a proposing transferor and a purchasing
       shareholder as to the value of the shares, the fair value will be fixed
       on the application of either party by the arbitration of a single
       arbitrator. Such an application must be made within 3 months of the date
       of the transfer notice. If the parties fail to agree on a single
       arbitrator, then the matter will be determined by the arbitration of 2
       arbitrators, one to be appointed by each party in dispute. The
       arbitrators shall appoint an umpire before entering upon their reference.

4.5.2  Upon the fair value being so fixed the value specified in the transfer
       notice will be deemed to have been the fair value given by this clause
       4.5.

                                       3
<PAGE>
 
4.5.3  The arbitration will be determined in accordance with the provisions
       contained in the Arbitration Act 1908 or any statutory modification or
       re-enactment of that Act for the time being in force. The costs of any
       arbitration will be borne equally between the proposing transfer and the
       purchasing shareholder.

4.6    RIGHT TO REVOKE
       If the fair value fixed in accordance with clause 4.5 is less than the
       sum specified by the proposing transferor in the proposing transferor's
       transfer notice as the sum the proposing transferor considers to be the
       value, the proposing transferor will be entitled at any time before the
       expiration of 7 days after the date of receiving notice of the award

proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner in which he reasonably believed to be in or not opposed to the best
interests of the. Corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

     Section 9.2  Indemnification: Actions by the Corporation. The Corporation

the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses, including attorneys' fees,
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his duty to the
Corporation unless and only to the extent that the court in which such action or
suit was brought shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is

          Statement; Our File No. 7539.2
          ----------------------------------------------------------------------

Ladies and Gentlemen:

     We are special counsel to ClimaChem, Inc., an Oklahoma corporation (the
"Company"), and the Guarantors named in the Registration Statement, all of whom
are subsidiaries of the Company (the "Guarantors," and together with the
Company, the "Issuers"), and have acted as such in connection with the filing of
a Registration Statement on Form S-4 (the "Registration Statement") under the
Securities Act of 1933, as amended (the "Securities Act"). The Registration
Statement covers up to $105,000,000 in aggregate principal amount of ClimaChem's
10 3/4% Series B Senior Notes due 2007 (the "New Notes") offered in exchange for
up to $105,000,000 in aggregate principal amount of outstanding 10 3/4% Senior
Notes due 2007 originally issued and sold in reliance upon an exemption from
registration under the Securities Act (the "Old Notes"). The Old Notes are, and
the New Notes will be, unconditionally guaranteed (the "Guarantees") by the
Guarantors. The Old Notes were issued under, and the New Notes will be issued
under, the Indenture, dated November 26, 1997 (the "Indenture"), among the
Issuers and Bank One, NA, as trustee. The exchange will be made pursuant to an
exchange offer (the "Exchange Offer") contemplated by the Registration
Statement. Capitalized terms used, but not otherwise defined, herein shall have
the meanings assigned to them in the Registration Statement.

     We have examined and are familiar with originals or copies, certified or
otherwise identified to our satisfaction, of the following:

     (i)  Minute Books of the Company and the Guarantors other than Climate
          Mate, Inc., a Province of Ontario, Canada corporation ("CMI"), The
          Environmental Group International Limited, a United Kingdom
          corporation ("TEGI"), Total Energy Systems Limited, an Australian
          corporation ("TES"), T.E.S. Mining Services Pty. Ltd., an Australian
          corporation ("TES Mining"), and Total Energy Systems (NZ) Limited, a
          New Zealand corporation ("TES (NZ)") (CMI, TEGI, TES, TES Mining, and
          TES (NZ) are collectively referred to as the "Foreign Guarantors").

     The documents and instruments listed above in (a) through (i) are referred
to herein as the "Documents."

     We have examined the originals or copies, certified or otherwise identified
to our satisfaction, of all such records of the Company and the Guarantors, as
we have deemed necessary or appropriate.  We have also examined certificates of
public officials, including certificates not identified above, certificates of
officers or representatives of the Company and the Guarantors, and such other
documents, certificates and corporate or other records as we have deemed
necessary or appropriate as a basis for the opinion set forth herein.

     In connection with this opinion, we have relied upon, among other things,
(a) the opinion issued by Corrs Chambers Westgarth, Australian counsel, dated
January 16, 1998, relating to TES, TES Mining and TES (NZ); (b) the opinion of
Clyde & Co., United Kingdom counsel, dated January 21, 1998, relating to TEGI;
and (d) the opinion issued by McLean & Kerr dated January 21, 1998, relating to
CMI (collectively, the "Opinions of Foreign Counsel"). Based upon the Opinions
of Foreign Counsel, we have assumed for the purposes of this opinion that each
of the Foreign Guarantors is duly incorporated, validly existing and in good
standing under the laws of each Foreign Guarantor's respective jurisdiction of
incorporation and that the Foreign Guarantors have duly authorized the
execution, delivery, and performance of the Indenture and Guarantees under the
laws of each Foreign Guarantors' respective jurisdiction of incorporation.

     In our examination we have assumed, without the duty to investigate, the
genuineness of all signatures, the legal capacity of natural persons, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as certified or photostatic
copies, and the authenticity of the originals of such copies. We have also
assumed the due authorization, execution and delivery of all documents referred
to herein by all parties thereto other than the Company and the Guarantors. As
to certain facts material to this opinion, we have relied upon certificates,
statements and representations of officers and other representatives of the
Company and the Guarantors.

     As to the validity and enforceability of the Indenture, the New Notes, and
the Guarantees, we have assumed that to the extent that the opinion expressed
herein relates to matters governed by the laws, rules and 
<PAGE>
 
ClimaChem, Inc.
January 22, 1998
Page 4

regulations of the State of New York, that the applicable laws, rules and
regulations of the State of New York are the same as the applicable laws, rules
and regulations of the State of Oklahoma. We have further assumed that the
Indenture as it relates to the Foreign Guarantors and the Guarantees issued by
the Foreign Guarantors and the transactions contemplated thereunder do not
conflict with, or constitute a default under (a) any law, rule or regulation of
Australia, New Zealand, Canada or the United Kingdom to which the Foreign
Guarantors or any of their properties may be subject; (b) any judicial or
regulatory order or decree of any governmental authority of Australia, New
Zealand, Canada or the United Kingdom applicable to the Foreign Guarantors; or
(c) any consent, approval, license, authorization or validation of, or filing,
recording, or registration with any governmental authority of Australia, New
Zealand, Canada or the United Kingdom applicable to the Foreign Guarantors.

     Based solely on our review of the foregoing Documents, and in reliance
thereon and on the Opinions of Foreign Counsel, and subject to the assumptions,
qualifications, limitations and exceptions set forth herein, we are of the
following opinion:

     1.   Each of the Company and the Guarantors (other than the Foreign
Guarantors) is a corporation duly incorporated and validly existing in good
standing under the laws of its respective jurisdiction of incorporation.

     2.   The execution and delivery of the Indenture has been duly authorized
by the Company and the Guarantors (other than the Foreign Guarantors), and the
Indenture constitutes a legal, valid and binding obligation of the Issuers,
enforceable against the Issuers in accordance with the terms thereof.

     3.   The New Notes have been duly authorized and, when duly executed by the
proper officers of the Company, duly authenticated by the Trustee and issued by
the Company in accordance with the terms of the Indenture and the Exchange
Offer, will constitute legal, valid and binding obligations of the Company, will
be entitled to the benefits of the Indenture and will be  enforceable against
the Company in accordance with their terms.

     4.   The Guarantees (other than those executed by the Foreign Guarantors)
have been duly authorized and, when the New Notes have been duly executed and
authenticated, and the Guarantees have been duly executed in accordance with the
terms of the Indenture, and the New Notes have been delivered to the holders as
described in the Prospectus, the Guarantees will constitute legal, valid and
binding obligations of the Guarantors, will be entitled to the benefits of the
Indenture, and will be enforceable against the Guarantors in accordance with
their terms.

     Based on the provisions of the Internal Revenue Code of 1986, as amended,
and the regulations promulgated thereunder, applicable judicial authority and
current administrative rulings and practice, all as of the date of this letter,
and all of which may change at any time, we are of the opinion that, as stated
in the section titled "Certain Federal Income Tax Consequences" contained 
<PAGE>
 
ClimaChem, Inc.
January 22, 1998
Page 5

in the Registration Statement, the exchange of Old Notes for New Notes pursuant
to the Exchange Offer will not be treated as an "exchange" for federal income
tax purposes, and there will be no federal income tax consequences to holders
exchanging Old Notes for New Notes pursuant to the Exchange Offer.

     We have expressed the foregoing opinions subject to the following
exceptions, qualifications and limitations:

     1.   The opinions expressed herein are limited to the laws of the State of
          Oklahoma, the General Corporation Law of the State of Delaware, and
          the applicable federal laws of the United States of the type typically
          applicable to transactions contemplated by the Exchange Offer, and we
          do not express any opinion with respect to the laws of any other
          country, state or jurisdiction. We call your attention to the fact
          that we are members of the Bar of the State of Oklahoma, and are not
          members of the Bar of Delaware.

     2.   This opinion is limited to the matters stated herein, and no opinion
          is implied or may be inferred beyond the matters expressly stated.

     3.   Although we express no opinion as to such, with respect to the
          Documents' choice of law provision applicable to the construction of
          contracts, Oklahoma follows the Restatement (Second) Conflict of Laws
          (S)(S) 187 and 188. See Dean Witter Reynolds, Inc. v. Shear, 796 P.2d
          296 (Okla. 1990). Section 187(2)(b) of such Restatement provides in
          pertinent part that:

                    [t]he law of the state chosen by the parties
                    ... will be applied, even if the particular
                    issue is one which the parties could not have
                    resolved by an explicit provision ..., unless
                                                           ------
                    ... application of the law of the chosen
                    ----------------------------------------
                    state would be contrary to a fundamental
                    ----------------------------------------
                    policy of a state which has a materially
                    ----------------------------------------
                    greater interest than the chosen state in the
                    ---------------------------------------------
                    determination of the particular issue and
                    -----------------------------------------
                    which, under the rule of (S) 188, would be
                    ------------------------------------------
                    the state of the applicable law in the
                    --------------------------------------
                    absence of an effective choice of law by the
                    --------------------------------------------
                    parties. (Emphasis added).
                    -------

     4.   Provisions of the Documents which purport to indemnify any party
          against or release any party from, liability for any acts are
          unenforceable to the extent such acts are determined to be unlawful,
          negligent, reckless, or constitute willful misconduct.

     5.   Those provisions of the Documents purporting to exculpate any party
          from any violation of usury laws by the ipso facto reduction of
          interest in excess of the maximum rate, and/or the application of such
          excess interest to principal or return thereof to the Company are
          unenforceable based on Oklahoma Preferred Finance & Loan Corporation
          v. Morrow, 497 P.2d 221 (1972).

     6.   The enforceability and effectiveness of the provisions of the
          Indenture, the New Notes and the Guarantees are limited by, and
          subject to (a) applicable bankruptcy, fraudulent conveyance or
          fraudulent transfer laws, insolvency, reorganization, moratorium, and
          other laws relating to or affecting creditors' rights generally now or
          hereafter in effect; or (b) applicable laws or principles of equity
          which may effect the exercise of certain rights and remedies and which
          may restrict the enforcement of certain remedies or the availability
          of certain equitable remedies.

     7.   As to enforceability of that portion of the Documents that provide if
          any provisions of the Documents are determined to be illegal, invalid
          or unenforceable, the remaining provisions remain in full force and
          effect where any such provision is an essential part of the Documents,
          and the parties would not have entered into the documents absent that
          provision.

     This letter speaks only as of the date hereof and is limited to present
statutes, regulations ad administrative and judicial interpretations.  We
undertake no responsibility to update or supplement this letter after the date
hereof.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and to the reference to our firm in the Registration Statement and the
Prospectus covering the Notes constituting a part thereof under the caption
"Legal Matters."

                                    Very truly yours,

          the documents and instruments submitted to us;

     (c)  That TES, TES (NZ), and TES Mining do not give the Guarantees or enter

          (d), (e), (f), (g), (h), and (i) of paragraph 3 of this opinion are,
          and continue to be, correct, and no relevant matter has been withheld
          from us, whether deliberately or inadvertently (and we have no reason
          to believe that this is not the case);

     (f)  That all acts of internal management relating to the entry into, and
          execution of, the Transaction Documents by TES, TES (NZ), and TES
          Mining have been duly performed and, without limitation, that:

          (i)  the resolutions of the directors referred to in paragraphs 3(e),

          (iv) any resolutions or special resolutions of the companies in
               general meeting which were required (if any) were properly passed

     (g)  That commercial benefit will accrue to TES, TES (NZ), and TES Mining
          from executing the Transaction Documents and undertaking the
          obligations on their parts under the Transaction Documents;

     (h)  That in connection with the entry into and the performance of their
          obligations under the Transaction Documents, the respective directors

          they seek to conduct, any relevant transactions or any associated

          Transaction Documents which might render the Transaction Documents or
          any of them or any relevant transactions or associated activities
          illegal, void, voidable or unenforceable;

     (j)  That in so far as any obligation of TES, TES (NZ) or TES Mining under
          the Transaction Documents is to be performed outside the Relevant
          Jurisdictions, its performance will not be illegal or ineffective by
          virtue of the law of the place of performance;

     (k)  That neither the Commissioner of Taxation of the Commonwealth of
          Australia nor the Commissioner of Taxes of New Zealand respectively
          have given, and will not give, a direction under Section 218 or
          Section 255 of the Income Tax Assessment Act of 1936 (Commonwealth of
          Australia) or Section 74 of the Sales Tax Assessment Act (No. 1) 1992
          or an equivalent provision of the New Zealand tax laws requiring TES,
          TES (NZ) or TES Mining respectively to deduct from sums payable by
          them under any of the Transaction Documents to the Initial Purchaser
          or any other party in accordance with the terms of any of the
          Transaction Documents an amount of Australian tax or New Zealand tax
          as the case may be payable by the payee;

     (l)  That TES, TES (NZ) and TES Mining were each solvent (within the
          meaning of Section 95A of the Corporations Law or within the meaning
          of Section 4 of the Companies Act 1993 (New Zealand) respectively) at
          the time which each entered into the Transaction Documents and each
          will not become insolvent (within the meaning of the relevant
          provision) because of, or because of matters including, entering into
          the Transaction Documents or any of them;

     (m)  That a person who appears, from notices or returns lodged under
          Section 242 or 335 of the Corporations Law to be a director or a
          secretary of TES or TES Mining has been

          duly appointed and has authority to exercise the powers and perform
          the duties customarily exercised or performed by a director or by a
          secretary, as the case may be, of a company carrying on a business of
          the kind carried on by TES or TES Mining respectively;

     (n)  That a person who appears, from notices or returns lodged under
          Section 12, 159 or 208 of the Companies Act 1993 (New Zealand) to be a
          director of TES (NZ) has been duly appointed and has authority to
          exercise the powers and perform the duties customarily exercised or
          performed by a director or by a secretary, as the case may be, of a
          company carrying on a business of the kind carried on by TES (NZ);

     (o)  All representations and warranties made in the Transaction Documents
          in favour of, or for the benefit of, TES, TES (NZ) or TES Mining by
          any other party to the Transaction Documents, are true and correct.

     We do not have actual knowledge of any thing which would render any of
     these assumptions wholly or partly incorrect.

          orders for specific performance) are discretionary and may not be
          awarded by the courts;

     (f)  Where under any of the Transaction Documents any of TES, TES (NZ), and
          TES Mining is required to make any payments on demand, courts may
          require that such be given a reasonable time after demand is made to
          comply with the demand before the payee will be permitted to realise
          or enforce any security for a failure to satisfy the demand;

     (g)  Any or all of the Transaction Documents may be unenforceable, invalid,
          void or at the action of TES, TES (NZ) or TES Mining voidable, if a

          respectively from executing the Transaction Documents and undertaking
          the obligations thereunder;

     (h)  We express no opinion as to whether the representations and warranties
          made, or given to be made, or given by TES, TES (NZ) and TES Mining in
          any of the Transaction Documents are correct, except insofar as (and
          to the extent that) any such representation or warranty relates to a

          on those matters is given in the terms set out in this opinion);

     (i)  A court may set aside a contract against a party on the application of

          mentioned party;

     (j)  We have relied on searches conducted at the offices of the Australian
          Securities Commission on 14 January 1998

                                                                          Page 7

          in respect of TES and TES Mining, but we note and rely on the fact
          that the records of the Australian Securities Commission available for
          public search may not be complete or up to date;

     (k)  We express no opinion as to:

          (i)  whether a judgment would be entered in a court in the Relevant
               Jurisdictions for an amount other than one expressed in
               Australian or New Zealand currencies respectively, although
               decisions of English courts allowing judgments in a foreign
               currency have been followed in Australian and New Zealand courts;

          (ii) as to the date upon which a conversion from foreign currency
               would be made for the purposes of enforcement of any judgment;

     (l)  A provision that a calculation, determination or certificate will be
          conclusive and binding or conclusive evidence will not apply to a
          calculation, determination or certificate which is fraudulent,
          manifestly inaccurate on its face or determined on an arbitrary basis
          and will not necessarily prevent a court from inquiring into the
          merits of any claim in relation to any such calculation, determination
          or certificate;

     (m)  We express no opinion on any provision in any of the Transaction
          Documents requiring written amendments and waivers insofar as it
          suggests that oral or other modifications, amendments or waivers could
          not be effectively agreed upon or granted by or between the parties or
          by a duly authorised agent;

     (n)  An obligation to pay an amount may be unenforceable if the amount is
          held to constitute a penalty and the obligation of TES, TES (NZ) or
          TES Mining under any of the Transaction Documents to pay interest on
          overdue amounts at a rate higher than the rate applying before the
          amount fell due may be held to constitute a penalty if it is not a
          genuine pre-estimate of the damage;

     (o)  Court proceedings may be stayed in the subject of the proceedings is
          concurrently before another court;

     (p)  An indemnity for legal costs or against liability for breach of any
          law may be unenforceable;

     (q)  A court will not give effect to a choice of laws to govern any of the
          Transaction Documents or to a 
<PAGE>
 
                                                                          Page 8

          submission to the jurisdiction of certain courts if to do so would be
          contrary to public policy in the Relevant Jurisdiction (but we are not
          aware of any reason why that would be so in relation to any of the
          Transaction Documents);

     (r)  Section 243H of the Corporations Law prohibits a public company and a
          child entity of a public company from giving financial benefit to a
          related party of that public company except as permitted by Divisions
          4 or 5 of Part 3.2A of the Corporations Law, and we express no opinion
          in relation to the application of that section;

     (s)  To the extent that any of the Transaction Documents requires TES, TES
          (NZ) or TES Mining to offer, allot or issue corporate securities to
          third parties, TES, TES (NZ) or TES Mining cannot do so unless and
          until it complies with the requirements of the Corporations Law or the
          Companies Act 1993 (New Zealand) respectively relating to the offer,
          issue or allotment of corporate securities.

     (t)  In order to be validly executed none of the Transaction Documents must
          take effect as a deed.

     (u)  We express no opinion as to whether the respective obligations
          undertaken by TES, TES (NZ) and TES Mining pursuant to the Transaction
          Documents may cause a default in any of the obligations to any party
          to whom TES, TES (NZ) or TES Mining has granted a charge over its
          assets.

6.   Opinion

     Based upon the assumptions and subject to the qualifications set out above,
     we are of the opinion that:

     (a)  TES has been duly incorporated under the laws of its place of
          incorporation and is validly registered and existing under the
          Corporations Law;

     (b)  TES has power to enter into and to perform its obligations under each
          of the Transaction Documents and has taken all necessary corporate and
          other action to authorise the execution, delivery and performance, in
          accordance with its terms of each of the Transaction Documents,
          including, without limitation, the Guarantees.

     (c)  TES Mining has been duly incorporated under the laws of its place of
          incorporation and is validly registered and existing under the
          Corporations Law;
<PAGE>
 
                                                                          Page 9

     (d)  TES Mining has power to enter into and to perform its obligations
          under each of the Transaction Documents and has taken all necessary
          corporate and other action to authorise the execution, delivery and
          performance, in accordance with its terms of each of the Transaction
          Documents, including, without limitation, the Guarantees.

     Based upon the assumptions and subject to the qualifications set out above
     and in reliance upon the matters set out in the annexed letter of advice
     from Bell Gully Buddle Weir, we are of the opinion that:

     (a)  TES (NZ) has been duly incorporated under the laws of its place of
          incorporation and is validly registered and existing under the laws of
          New Zealand;

     (b)  TES (NZ) has power to enter into and to perform its obligations under
          each of the Transaction Documents and has taken all necessary
          corporate and other action to authorise the execution, delivery and
          performance, in accordance with its terms of each of the Transaction
          Documents, including, without limitation, the Guarantees.

TOTAL ENERGY SYSTEMS (NZ) LIMITED

We refer to your facsimile of 15 January 1998.

We have reviewed the certificate of incorporation of Total Energy Systems (NZ)
Limited ("TES(NZ)") and the constitution of TES(NZ). We set out below our advice
in response to the questions contained in your facsimile of 15 January 1998.

Your instructions

You asked us the following:

 .    has TES(NZ) been duly incorporated under the laws of New Zealand and is it
     validly registered and existing under those laws?

 .    does TES(NZ) have the power to enter into financial accommodations and to
     give securities, including guarantees, for a debt, liability or obligation
     of any other person?

 .    are there any relevant restrictions on the powers of TES(NZ) or
     restrictions in respect of the exercise of the powers referred to in the
     paragraph above?

 .    who may exercise, on behalf of TES(NZ), the powers referred to above and
     what action must be taken to authorise the execution, delivery and
     performance of the necessary documentation?
<PAGE>
 
16 January, 1998

Our advice

We address these questions in turn below.

Incorporation

We understand that you spoke with Jacky Bruce of our office yesterday on this
matter.  We confirm that TES(NZ) has been duly incorporated under the laws of
New Zealand and is validly registered and existing under the laws of New
Zealand.

Power to enter into financial accommodation

TES(NZ) has the capacity and powers set out in section 16 of the Companies Act
1983 (the "Companies Act").  That section provides that, subject to the
Companies Act and any other Act, and the general law, a company has, both within
and outside New Zealand:

 .    the full capacity to carry on or undertake any business or activity, do any
     act, or enter into any transaction; and

 .    for the purposes of the paragraph above, full rights, powers and
     privileges.

Section 16(2) provides that a company's constitution may contain a provision
relating to capacity and powers only if the provision restricts the capacity or
powers of the company.  The constitution of TES(NZ) does not contain any
restriction on the power of TES(NZ) to enter into financial accommodations or to
give securities, including guarantees, for a debt, liability or obligation of
any other person ("financial transactions").

We therefore confirm that TES(NZ) has the power to enter into financial
transactions.

Restrictions on power of TES(NZ)

As stated above, we confirm that neither the constitution of TES(NZ) or the
Companies Act imposes relevant restrictions on the powers of TES(NZ) or
restrictions in respect of the power to enter into financial transactions.

Exercise of TES(NZ)'s powers
<PAGE>
 
16 January 1998
Page 3

Clause 12.1.1 of the constitution of TES(NZ) states that the business and
affairs of the company must be managed by or under the direction or supervision
of the board.

Clause 12.1.2 provides that the board has, and may exercise, all the powers
necessary for managing, directing and supervising the management, business and
affairs of the company except to the extent that TES(NZ)'s constitution or the
Companies Act expressly requires those powers to be exercised by the
shareholders or any other person.  Those clauses substantially repeat sections
128(1) and 128(2) of the Companies Act.

Clauses 12.1.1 and 12.1.2 are both expressly stated to be subject to clause 8 of
the Constitution of TES(NZ).  Clause 8.1 allows the shareholders of TES(NZ) to
pass a resolution binding on the board relating to or for the purpose of
managing or directing or supervising the management or supervision of the
business or affairs of the company.

Subject to clause 8, therefore, the board of TES(NZ) may exercise the company's
powers to enter into financial transactions.

Accordingly, the authorization of the execution, delivery and performance of the
necessary documentation is a matter for the board of TES(NZ).

Clause 13.1 of the constitution of TES(NZ) adopts the provisions of the Third
Schedule to the Companies Act, which deals with proceedings of the board of a
company.  Clause 5(3) of the Third Schedule provides that a resolution of the
board is passed if it is agreed to by all directors present without descent or
if a majority of the votes cast on it are in favour of it.

The methods by which TES(NZ) may enter into a contract are set out in section
180 of the Companies Act.  An obligation which, if entered into by a natural
person, would, by law, be required to be deed, may be entered into on behalf of
the company in writing signed under the name of the company by:

 .    two or more directors of the company; or

 .    if there is only one director, by that director whose signature must be
     witnessed;

 .    an attorney.
<PAGE>
 
16 January 1998
Page 4

It appears from our summary internet search of the Companies Office database
that TES(NZ) has only one director.

Other matters

There are a number of issues raised by the Companies Act that may be relevant to
the transaction and of which you should be aware. We describe each of these
briefly below.  We cannot, of course, advise whether these will be relevant to
this transaction.  The matters discussed below are questions of fact which, if
they apply, have legal consequences.  If you consider that any of these matters
may be relevant, we will provide you with appropriate advice at that stage.

Major transactions

The Companies Act states that a company must not enter into a major transaction
unless it is approved by special resolution or is contingent on that approval.
A major transaction means, in general terms:

 .    the acquisition or disposal of assets the value of which is more than half
     the value of the company's assets before the acquisition or disposition; or

 .    a transaction that has or is likely to have the effect of the company
     acquiring rights or interests or incurring obligations or liability the
     value of which is more than half the value of the company's assets before
     the transaction.

A floating charge is excluded from the second limb of the definition of major
transaction given above.

A special resolution is a resolution passed by a majority of 75 percent of the
shareholders, unless the company's constitution provides for a higher majority.
TES(NZ)'s constitution specifies a special resolution as requiring 75 percent of
the votes of those shareholders entitled to vote and voting on the question.

Financial assistance

Financial assistance is, in broad terms, some form of assistance given by a
company to a third party to purchase shares in the company.  Financial
assistance includes a loan, a guarantee and the provision of security.  The
financial assistance may be direct or indirect and may be for the purpose of, or
merely in connection with, the purchase of a share in the company.
<PAGE>
 
16 January 1998
Page 5

The Companies Act permits financial assistance in three circumstances:

 .    with the consent of all shareholders; or

 .    where the assistance does not exceed 5 percent of the shareholders' funds
     of the company; or

 .    without the shareholders' consent, subject to other controls.

Depending on which of these three forms of permitted financial assistance is
relevant, the Companies Act requires the board to resolve and certify certain
matters and set out the grounds for the board's conclusion.  In addition, the
Companies Act requires the company to satisfy a solvency test.  To satisfy the
solvency test

 .    a company must be able to pay its debts as they become due in the ordinary
     course of business; and

 .    the value of the company's assets must be greater than the value of its
     liabilities, including contingent liability.

Directors interested in a transaction of the company

Section 140 of the Companies Act requires a director of a company, on becoming
aware that he or she is "interested" in a transaction to enter in the interests
register of the company and, if the company has more than one director, disclose
to the board of the company:

 .    if the monetary value of the director's interest is able to be quantified,
     the nature and monetary value of that interest; or

 .    if the monetary value of the director's interest cannot be quantified, the
     nature and extent of that interest.

Section 139 of the Companies Act defines the term "interested".  A director of a
company is interested in a transaction to which the company is a party if, and
only if, the director:

 .    is a party to, or will or may derive a material financial benefit from, the
     transaction; or

 .    has a material financial interest in another party to the transaction; or
<PAGE>
 
16 January 1998
Page 6

 .    is a director, officer, or trustee of another party to, or person who will
     or may derive a material financial benefit from, the transaction, not being
     a party or person that is a holding company, wholly owned subsidiary of the
     company or a wholly owned subsidiary of a holding company of which the
     company is also a wholly owned subsidiary; or

 .    is the parent, child, or spouse of another party to, or person who will or
     may derive material financial benefit from, the transaction; or

 .    is otherwise directly or indirectly materially interested in the
     transaction.

A transaction entered into by the company in which a director of the company is
interested may be avoided by the company at any time within three months after
the transaction is disclosed to all the shareholders.  However, a transaction
cannot be avoided if the company receives fair value under it.

An interested director to a transaction may nevertheless perform any act as a
director in relation to the transaction as if he or she were not interested in
the transaction.

Liquidation "claw-back"

You should also be aware of the "claw-back" provision of Part XVI (Liquidation)
of the Companies Act and, in particular, the sections relating to transactions
having a preferential effect and transactions at an under value.

Section 292 broadly provides that a "transaction" made by a company otherwise
than in ordinary course of business at a time when that company is unable to pay
its due debts is voidable against the company's liquidator if:

 .    it is entered into within two years before commencement of liquidation; and

 .    the transaction enabled another person to receive more towards satisfaction
     of a debt than the person would have received or would have been likely to
     receive in the company's liquidation.

If the transaction was made within six months before the commencement or
liquidation, the person opposing the application to satisfy the transaction must
prove that the company was able to pay 
<PAGE>
 
16 January 1998
Page 7

its due debts when the transaction was made and that the transaction was
undertaken in the ordinary course of business.

In broad terms, section 297 allows the liquidator to recover from another party
to a transaction the amount by which the value of the consideration or benefit
provided by the company exceeded the consideration or benefit received by the
company.  A liquidator may challenge a transaction under this section where:

 .    a transaction was entered into by a company within one year before the
     commencement of the liquidation;

 .    the value of the consideration or benefit received by the company was less
     than the value of the consideration provided by the company;

 .    the company became unable to pay its due debts as a result of the
     transaction; and

 .    when the transaction was entered into, the other party to the transaction
     knew or ought to have known that the company would become unable to pay its
     due debts as a result of the transaction.

A transaction includes the giving of a guarantee by a company.

Copies of sections 292 and 297 are attached to this facsimile for your
information.

The ability of a liquidator to challenge transactions having a preferential
effect or transactions at an under value cannot, of course, be set aside at the
time that the transaction is entered into by means of a shareholders or
directors resolution or otherwise.

TOTAL ENERGY SYSTEM (NZ) LIMITED ("TES(N2)")

We refer to your facsimile of 22 January 1998 regarding the appointment of 
directors in Total Energy Systems (NZ) Limited ("TES(NZ)").

In our facsimile to you of 16 January 1998, we advised that an internet search 
of the Companies Office Database recorded Kevin James Herman as the only 
director to TES(NZ).

Further to our facsimile, we have since received from you faxed copies of 
executed directors' consents for James Leon Wewars, William Robert Manion and 
Paul Harris Rydund. These consents are in the form required by the Companies Act
1993 and have been executed in accordance with clause 10 of TES(NZ)'s 
constitution. We also received the shareholder's resolutions approving the 
appointment of each of the directors.

Accordingly, on the basis of the information we have been given by you, it
appears that TES(NZ) has four directors. Although the contest mention above have
not yet been filed with the New Zealand Companies Office, this does not affect
the validity of the appointments.

Please contact either myself or Chris O'Brian if you wish to discuss this matter
further.

Yours faithfully

/s/ David Martin

     Re:  Climate Mate, Inc.

Dear Sir:

     We are special counsel to Climate Mate, Inc., a corporation organized under
the laws of the Province of Ontario, Canada (the "Company").  We have been
requested to render certain opinions in connection with the authorization,

2.   ClimaChem has issued $105,000,000 in aggregate principal amount of its 10
     3/4% Senior Notes, due 2007 (the "Old Notes"), and has agreed to offer to
     exchange (the "Exchange Offer") the Old Notes for up to $105,000,000 in
     aggregate principal amount of ClimaChem's 10 3/4% Senior Notes, Series B,
     due 2007 (the "New Notes"), pursuant to the terms of a Registration Rights
     Agreement, dated November 26, 1997, between ClimaChem, the Company, the

3.   the Company has guaranteed the Old Notes, and has agreed to guarantee the

                                                               January 21, 1998 
                                                                         Page 2

          acquired or designated subsidiary of ClimaChem;

Dear Sirs:

Registration on Form S-4; Our File No. 7539.2

We have acted as English legal advisers to The Environmental Group International
Limited, a company incorporated under the laws of England ("the Company"), and a
wholly owned subsidiary of ClimaChem, Inc.  ClimaChem has issued US$105,000,000
in aggregate principal amount of its 10 3/4% Senior Notes, due 2007 ("the Old
Notes"), and has agreed to offer to exchange ("the Exchange Offer") the Old
Notes for up to US$105,000,000 in aggregate principal amount of ClimaChem's 10
3/4% Senior Notes, Series B, due 2007 ("the New Notes"), pursuant to the terms
of a Registration Rights Agreement dated 26 November 1997 between ClimaChem, the
Company, the other listed guarantors and Wasserstein Perella Securities, Inc.
The Company has guaranteed the Old Notes and has agreed to guarantee the New
Notes, pursuant to the terms of the Indenture (as defined) under which the Old
Notes were issued and the New Notes will be issued.  The Exchange Offer is to be
undertaken by means of a Registration on Form S-4 ("Registration Statement") to
be filed with the Securities and Exchange Commission and the prospectus
contained therein (the "Prospectus").

In connection with this opinion, we have examined the following documents and
instruments:

1.   Copy of Indenture, dated 26 November 1997 ("the Indenture") between
     ClimaChem, BankOne, NA, as trustee, and the Company, Total Energy Systems
     Limited, T.E.S. Mining Services Pty. Ltd., Total Energy Systems (NZ) Ltd.,
     the Environmental Group, Inc., International Environmental Corporation,
     Climate Master, Inc., Climate Mate, Inc., CHP Corporation, KOAX
     Corporation, APR Corporation, LSB Chemical Corp., El Dorado Chemical
     Company, Slurry Explosive Corporation, Universal Tech Corporation,
     Northwest Financial Corporation and DSN Corporation (collectively "the
     Guarantors").

2.   Copy of Guarantee by the Company of ClimaChem's 10 3/4% of Senior Notes,
     Series B, due 2007 ("the Guarantee").

3.   Original Certificate of Incorporation and copies of Memorandum and Articles
     of Association.

4.   Unanimous written consent of the directors of the Company relating to the
     execution and delivery of the Indenture and the Guarantee.

5.   Such other documents and instruments as we have considered necessary.

Based upon the foregoing, and on the assumption of the copies' conformity to the
original documents, and of the accuracy and completeness of information (as of
today's date) disclosed by a Companies House search and by the Central Registry
of Winding-up Petitions and that the Information has not since been materially
altered or added to, we are of the opinion that:

     1.   The Company has been duly incorporated and is validly existing under
          the laws of England.

     2.   The Company has the power to enter into and perform its obligations
          under the Indenture and the Guarantee and has taken all necessary
          corporate and other action to authorise the execution, delivery and
          performance of the Indenture and, when issued, the Guarantee.

The opinions expressed herein are limited to English law.  We have not made any
investigations of, and do not express any opinion as to any other laws or the
laws of any other jurisdiction.

                                Promissory Note

                                                         Oklahoma City, Oklahoma
$10,000,000                                                    November 26, 1997


     For Value Received, the undersigned LSB Industries, Inc. (the "Borrower")
promises to pay to the order of ClimaChem, Inc. (the "Lender") at the Lender's
office at 16 South Pennsylvania Avenue, Oklahoma City, Oklahoma, the principal

     The Borrower promises to pay interest on the balance of principal remaining

     Section 1. Interest.

          Section 1.1. Interest Rates. (a) Subject to all of the terms and

shall bear interest a rate per annum of 10 3/4%; provided that if the Borrower
shall fail to pay when due the outstanding principal indebtedness then due
hereunder (whether by lapse of time, acceleration or otherwise), such principal
indebtedness shall bear interest, whether before or after judgment, until
payment in full thereof at the rate per annum of 10 3/4% Interest shall be due
and payable on June 1 and December 1, commencing June 1, 1998.

     Section 2. Payments; Prepayments.

Lender at its principal office in Oklahoma City, Oklahoma. All such payments
shall be made in lawful money of the United States of America, in immediately
available funds at the place of payment, without setoff or counterclaim. Unless
the Borrower otherwise directs, principal payments made prior to any Event of
Default hereunder, shall be applied, first, to interest and second, to the
payment of principal. No amount paid or prepaid on this Note may be borrowed
again.

          Section 2.2. Voluntary Prepayments. The Borrower shall have the option
of prepaying without premium or penalty and in whole or in part any portion of
this Note, such prepayment to be made by the payment of the principal amount to
be prepaid and accrued and unpaid interest thereon to the date of prepayment.
<PAGE>
 
          Section 2.3. Mandatory Repayment. Except as provided below, the
Borrower will not, and will not permit any of its subsidiaries (other than
Lender and its subsidiaries) to, convey, sell, transfer, assign or otherwise
dispose of, directly or indirectly, any of its assets for cash, and including
any sale or other transfer of outstanding equity interests of any subsidiary of
the Borrower (other than Lender and its subsidiaries) for cash, whether by the
Borrower or a subsidiary (other than Lender and its subsidiaries), in a single
transaction or through a series of related transactions (any of the foregoing,
an "Asset Sale"), unless within 30 days after the receipt of Net Cash Proceeds
(as defined below) of such Asset Sale, 50% of such Net Cash Proceeds are applied
to the prepayment of the Notes without premium or penalty, plus accrued and
unpaid interest on the principal amount paid to the date of prepayment.

          Notwithstanding the foregoing provisions of the prior paragraph, the
provisions of the prior paragraph shall not apply to the following:

               (i)    the conveyance, sale, transfer, assignment or other
disposition of inventory acquired and held for resale in the ordinary course of
business;

               (ii)   the conveyance, sale, transfer, assignment or other
disposition of accounts receivable;

               (iii)  the sale or disposition of damaged, worn out or other
obsolete property;

               (iv)   the conveyance, sale, transfer, assignment or other
disposition of assets to the Borrower or any of its subsidiaries (other than the
Lender and its subsidiaries);

               (v)    the conveyance, sale, transfer, assignment or other
disposition of assets having a value of $500,000 or less in a single transaction
or a series of related transactions.

               "Net Cash Proceeds" means the aggregate amount of cash received
by the Borrower and its subsidiaries (other than the Lender and its
subsidiaries) in respect of an Asset Sale, less (i) the sum of all payments,
fees, commissions and expenses (including, without limitation, the fees and
expenses of legal counsel and investment banking fees and expenses) incurred in
connection with such Asset Sale, (ii) the amount (estimated reasonably and in
good faith by the Borrower) of income, franchise, sales and other applicable
taxes required to be paid by the Borrower or any of its respective subsidiaries
(other than the Lender and its subsidiaries) in connection with such Asset Sale,
(iii) the amount of cash resulting from an Asset Sale in a foreign jurisdiction
that is prohibited by law from being transferred to the United States or
exchanged for U.S. dollars and (iv) the amount

                                       2

used to prepay other senior indebtedness of the Borrower or a subsidiary which
requires such prepayment in accordance with its terms.

     Section 3. Events of Default and Remedies.

          Section 3.1. Events of Default. Any one or more of the following shall
constitute an "Event of Default" hereunder: (a) non-payment when due of any
principal of or interest on this Note and the continuance of any such failure
for 30 days; (b) the institution by or against the Borrower of any bankruptcy or
similar proceeding for the relief of debtors or the appointment of any receiver
for any such party or any of his/her property and such act remains unstayed for
a period of 90 consecutive days; and (c) the making of the Borrower of an
assignment for the benefit of creditors.

          Section 3.2. Acceleration. When any Event of Default has occurred and
is continuing, the Lender may, by notice to the Borrower, declare the principal
of and interest on this Note to be due and payable and upon such declaration
this Note, including both principal and interest, and all other amounts due
under this Note shall be and become immediately due and payable without further
demand, presentment, protest or notice of any kind. Also in any such event, the
Lender shall have the right to exercise any other action, right, power or remedy
permitted by law.

     Section 4. Miscellaneous.

          Section 4.1. No Waiver of Rights. No delay or failure on the part of
the Lender or on the part of the holder or holders of this Note in the exercise
of any power or right shall operate as a waiver thereof or as an acquiescence in
any Event of Default, nor shall any single or partial exercise of any power or
right preclude any other or further exercise thereof, or the exercise of any
other power or right, and the rights and remedies hereunder of the Lender and of
the holder or holders of this Note are cumulative to, and not exclusive of, any
rights or remedies which any of them would otherwise have.

          Section 4.2. Amendments. No amendment, modification or waiver of any
provision of this Note, nor consent to any departure by the Borrower therefrom,
shall in any event be effective unless the same shall be in writing and signed
by the Lender, provided, however, that the Lender may not take any such action
and such action shall not be effective without the consent of a majority
aggregate principal amount of the Lender's 10 3/4% Senior Notes due 2007 then
outstanding.

          Section 4.3. Holidays. If any payment hereunder becomes due and
payable on a day which is not a business day, the due date of such payment shall
be extended to the next succeeding business 

                                       3
<PAGE>
 
day on which date such payment shall be due and payable. In the case of any
payment of principal falling due on a day which is not business day, interest on
such principal amount shall not continue to accrue during such extension.

herein shall be in writing, except as otherwise specifically provided for
hereinabove, and shall be deemed to have been given or made when served

               ---------------                                             
conditions set forth in this Agreement, and upon any Borrower's request from
time to time, make revolving loans (the "Revolving Loans") to such Borrower up
to the limits of the Availability.  The Lender, in its discretion, may elect to
exceed the limits of the Availability on one or more occasions, but if it does

                                       18
<PAGE>
 
so, the Lender shall not be deemed thereby to have changed the limits of the
Availability or to be obligated to exceed the limits of the Availability on any
other occasion.  If the unpaid balance of the Revolving Loans exceeds the
Availability (with Availability for this purpose determined as if the amount of
the Revolving Loans were zero), then the Lender may refuse to make or otherwise
restrict Revolving Loans on such terms as the Lender determines until such
excess has been eliminated.  Each Borrower may request Revolving Loans either
orally or in writing, provided, however, that each such request with respect to
Reference Rate Loans shall be made no later than 1:00 p.m. (Los Angeles,
California time).  Each oral request for a Revolving Loan shall be conclusively
presumed to be made by a person authorized by the Borrower to do so and the
crediting of a Revolving Loan to the Borrower's deposit account, or transmittal
to such Person as the Borrower shall direct, shall conclusively establish the
obligation of the Borrower to repay such Revolving Loan.  The Lender will charge
all Revolving Loans and other Obligations to a loan account of the Borrower
maintained with the Lender.  All fees, commissions, costs, expenses, and other
charges due from the Borrower pursuant to the Loan Documents, and all payments
made and out-of-pocket expenses incurred by Lender and authorized to be charged
to the Borrower pursuant to the Loan Documents, will be charged as Revolving
Loans to the Borrower's loan account as of the date due from the Borrower or the
date paid or incurred by the Lender, as the case may be.

          2.2  Availability Determination.  Availability of each Borrower will
               --------------------------                                     
be determined by the Lender in accordance with the terms of this Agreement, each
day on the basis of such relevant information as the Lender deems appropriate to
consider, including the collateral summary reports and such other information
regarding the Accounts and the Inventory as the Lender shall obtain from such
Borrower.

          2.3  Letters of Credit.  The Lender will, subject to the terms and
               -----------------                                            
conditions of this Agreement and the "Letter of Credit Agreement" as hereinafter
defined, and upon any Borrower's request from time to time, cause merchandise
letters of credit (the "Merchandise L/C's") or standby letters of credit (the
"Standby L/C's") to be issued for the Borrower's account (the Merchandise L/C's
and the Standby L/C's being referred to collectively as the "Letters of
                                                             ----------
Credit").  The Lender will not cause to be opened any Letter of Credit if:  (a)
- ------
the maximum face amount of the requested Letter of Credit, plus the aggregate
undrawn face amount of all outstanding Letters of Credit under this Agreement
and the other LSB-Related Loan Agreements, would exceed Eleven Million and
No/100 Dollars ($11,000,000); or (b) the maximum face amount of the requested
Letter of Credit, and all commissions, fees, and charges due from Borrower to
Lender in connection with the opening thereof, would cause the Availability to
be exceeded at such time.  In addition, with respect to any Merchandise L/C, the
requested term of such Letter of Credit may not exceed 180 days, and no
Merchandise L/C may by its terms be scheduled to be outstanding on the
Termination Date.  Standby L/C's may have terms that extend beyond the
Termination Date but, upon termination of this Agreement, all Letters of Credit
must be either terminated with the consent of the beneficiary thereof, replaced
with a letter of credit provided by a financial institution acceptable to
Lender, collateralized by cash or cash equivalent, or otherwise satisfied in a
manner acceptable to Lender.  The Letters of Credit shall be governed by a
Letter of Credit Financing Agreement -  Supplement to Amended and Restated Loan
and Security Agreement between the Lender and the Borrower ("Letter of Credit
                                                             ----------------

indemnify and hold the Lender harmless from any and all obligations now or
hereafter owing by the Lender to the Bank arising from or related to such Swap
Transactions pursuant to the indemnity referred to in clause (c) below.  EDC
agrees to pay the Bank all amounts owing to the Bank pursuant to the Swap
Transactions.  In the event EDC shall not have paid to the Bank such amounts,
the Lender shall pay the Bank and such amounts when paid by the Lender shall
constitute a Revolving Loan of EDC which shall be deemed to have been requested
by EDC.  EDC acknowledges and agrees that the obtaining of Swap Transactions
from the Bank (a) is in the sole and absolute discretion of the Bank, (b) is
subject to all rules and regulations of the Bank, and (c) is due to the Bank
relying on the indemnity of the Lender to the Bank with respect to the
obligations of EDC to the Bank in connection with the Swap Transactions.  EDC

times the amount of all outstanding Swap Transactions.

manner provided in Section 3.2. If at any time Revolving Loans are outstanding
                   ------------
with respect to which notice has not been delivered to Lender in accordance with
the terms of this Agreement specifying the basis for determining the interest
rate applicable thereto, then those Revolving Loans shall be Reference Rate
Loans and shall bear interest at a rate determined by reference to the Reference
Rate until notice to the contrary has been given to the Lender and such notice
has become effective. Except as other wise provided herein, the amounts charged
as Revolving Loans shall bear interest at the following rates (the "Applicable
Interest Rate"):

          (i)  For all amounts charged as Revolving Loans other than Eurodollar
     Rate Loans, including all Revolving Loans which are Reference Rate Loans,
     then at a fluctuating per annum rate equal to one and one-half percent
     (1.50%) per annum (the "Reference Rate Margin") plus the Reference Rate;
     and

          (ii) If the Revolving Loans are Eurodollar Rate Loans, then at a per
     annum rate equal to three and seven-eighths percent (3.875%) per annum (the
     "Eurodollar Margin") plus the Eurodollar Rate determined for the applicable
     Interest Period.

     Notwithstanding the foregoing, if, during any month, the sum of the average
     "Availability" (as defined in each of the LSB-Related Loan Agreements) of
     the LSB Consolidated

                                       20
<PAGE>
 
     Borrowing Group under all of the LSB-Related Loan Agreements is less than
     $6,300,000, then, during the following month, the Reference Rate Margin
     will be increased to two percent (2%) and the Eurodollar Margin will be
     increased to four and three-eighths percent (4.375%).

     In addition, if the LSB Adjusted Tangible Net Worth equals or exceeds
     $72,500,000, as reflected on LSB's most current quarterly Financial
     Statements, provided no Event of Default has occurred and is continuing,
     then for so long as the LSB Adjusted Tangible Net Worth is at least
     $72,500,000, the Reference Rate Margin will be reduced to one percent (1%)
     and the Eurodollar Margin will be reduced to three and three-eighths
     percent (3.375%), and the reduction will be effective as of the first day
     of the month following receipt by Lender of the applicable quarterly
     Financial Statements.

     Finally, if the LSB Adjusted Tangible Net Worth equals or exceeds
     $84,000,000, as reflected on LSB's most current quarterly Financial
     Statements, provided no Event of Default has occurred and is continuing,
     then for so long as the LSB Adjusted Tangible Net Worth is at least
     $84,000,000, the Reference Rate Margin will be reduced to one-half of one
     percent (.50%) and the Eurodollar Margin will be reduced to two and seven-
     eighths percent (2.875%), and the reduction will be effective as of the
     first day of the month following receipt by Lender of the applicable
     quarterly Financial Statements.

     Each change in the Reference Rate shall be reflected in the interest rate
described in (i) above as of the effective date of such change.  All interest
charges shall be computed on the basis of a year of three hundred sixty (360)
days and actual days elapsed.  Except as otherwise provided herein, (1) interest
accrued on each Eurodollar Rate Loan shall be payable in arrears on each
Eurodollar Interest Payment Date applicable to such Eurodollar Rate Loan, and
(2) interest accrued on the Reference Rate Loans will be payable in arrears on
the first day of each month hereafter.

          (b)  Default Rate.  If any Event of Default occurs, then, while any
               ------------                                                  
such Event of Default is continuing, all Loans shall bear interest at an
increased rate of interest equal to the Applicable Interest Rate thereto plus
                                                                         ----
two percent (2.0%) per annum, and the Letter of Credit Fee and the Swap
Transaction Fee shall each be increased to three percent (3%) per annum.

          3.2  Eurodollar Borrowings: Conversion or Continuation.
               ------------------------------------------------- 

          (a)  Subject to the provisions of Section 3.3, each Borrower shall
                                            -----------
have the option: (i) to request the Lender to make a Revolving Loan as a
Eurodollar Rate Loan; (ii) to convert all or any part of the outstanding
Revolving Loans from Reference Rate Loans to Eurodollar Rate Loans, (iii) to
convert all or any part of the outstanding Revolving Loans from Eurodollar Rate
Loans to Reference Rate Loans on the expiration of the Interest Period
applicable thereto; (iv) upon the expiration of any Interest Period applicable
to any outstanding Eurodollar Rate Loan, to continue all or any portion of such
Eurodollar Rate Loan as a Eurodollar Rate Loan; provided, however, that no
                                                --------  -------
outstanding Loans may be converted into or continued as, Eurodollar Rate Loans
when any Event or Event of Default has occurred and is continuing.

                                       21
<PAGE>
 
          (b)  Whenever the Borrower elects to borrow, convert into or continue
Eurodollar Rate Loans under this Section 3.2, the Borrower shall notify the
                                 -----------  
Lender in writing or telephonically no later than 11:00 a.m. (Los Angeles,
California time) two (2) Business Days in advance of the requested
borrowing/conversion/continuation date. The Borrower shall specify (1) the
borrowing/conversion/continuation date (which shall be a Business Day), (2) the
amount and type of the Revolving Loans to be borrowed/converted/continued, and
(3) the nature of the requested borrowing/ conversion/continuation. In the event
that the Borrower should fail to timely notify the Lender to continue to convert
any existing Eurodollar Rate Loan, such Loan shall, on the last day of the
Interest Period with respect to such Revolving Loan, convert to a Reference Rate
Loan.

          (c)  The officer of the Borrower authorized by the Borrower to request
Revolving Loans on behalf of the Borrower shall also be authorized to request a
conversion/continuation on behalf of the Borrower.  The Lender shall be entitled
to rely on such officer's authority until the Lender is notified to the contrary
in writing.  The Lender shall have no duty to verify the  authenticity of the
signature appearing on any written notification or request and, with respect to
an oral notification or request, the Lender shall have no duty to verify the
identity of any individual representing himself as one of the officers
authorized to make such notification or request on behalf of the Borrower.  The
Lender shall incur no liability to the Borrower in acting upon any telephonic
notice or request referred to in this Section 3.2, which the Lender believes in
                                      -----------                              
good faith to have been given by an officer authorized to do so on behalf of the
Borrower, or for otherwise acting in good faith under this Section 3.2 and, upon
                                                           -----------          
lending/conversion/continuation by the Lender in accordance with this Agreement
pursuant to any such telephonic notice, the Borrower shall have effected the
borrowing/conversion/continuation of the applicable Loans hereunder.

          (d)  Any written or telephonic notice of conversion to, or borrowing
or continuation of, Revolving Loans made pursuant to this Section 3.2 shall be
                                                          -----------
irrevocable and the Borrower shall be bound to borrow, convert or continue in
accordance therewith.

          3.3  Special Provisions Governing Eurodollar Rate Loans.
               --------------------------------------------------  
Notwithstanding any other provisions to the contrary contained in this
Agreement, the following provisions shall govern with respect to Eurodollar Rate
Loans as to the matters covered:

          (a)  Amount of Eurodollar Rate Loans.  Each election of, continuation
               -------------------------------                                 
of, or conversion to a Eurodollar Rate Loan, shall be in a minimum amount of
Five Million Dollars ($5,000,000) and in integral multiples of One Million
Dollars ($1,000,000) in excess of that amount.

          (b)  Determination of Interest Period.  The Interest Period for each
               --------------------------------                               
Eurodollar Rate Loan shall be for a three (3) month period.  The determination
of Interest Periods shall be subject to the following provisions:

               (i)  In the case of immediately successive Interest Periods, each
     successive Interest Period shall commence on the day on which the next
     preceding Interest Period expires.

               (ii) If any Interest Period would otherwise expire on a day which
     is not a Business Day, the Interest Period shall be extended to expire on
     the next succeeding Business 

                                       22
<PAGE>
 
     Day; provided, however, that if the next succeeding Business Day occurs in
          --------  -------
     the following calendar month, then such Interest Period shall expire on the
     immediately preceding Business Day.

               (iii)   The Borrower may not select an Interest Period for any
     Eurodollar Rate Loan, which Interest Period expires later than the
     Termination Date.

               (iv)    There shall be not more than two (2) Interest Periods in
     effect at any one time, and no more than two (2) Interest Periods may begin
     during any calendar month.

               (v)     If an Interest Period starts on a date for which no
     numerical correspondent exists in the month in which such Interest Period
     ends, such Interest Period will end on the last Business Day of such month.

          (c)  Determination of Interest Rate.  As soon as practicable after
               ------------------------------                               
11:00 a.m. (Los Angeles, California time) on the Eurodollar Interest Rate
Determination Date, the Lender shall determine (which determination shall,
absent manifest error, be presumptively correct) the Interest Rate for the
Eurodollar Rate Loans for which an Interest Rate is then being determined and
shall promptly give notice thereof (in writing or by telephone confirmed in
writing) to the Borrower.

          (d)  Substituted Rate of Borrowing.  In the event that on any
               -----------------------------                           
Eurodollar Interest Rate Determination Date the Lender shall have determined
(which determination shall, absent manifest error, be presumptively correct and
binding upon all parties) that:

               (i)     by reason of any changes arising after the date of this
     Agreement affecting the interbank Eurodollar market or affecting the
     position of Bank or Lender in such market, adequate and fair means do not
     exist for ascertaining the applicable interest rates by reference to which
     the Eurodollar Rate then being determined is to be fixed; or

               (ii)    by reason of (1) any change after the date of this
     Agreement in any applicable law or governmental rule, regulation or order
     (or any interpretation thereof and including the introduction of any new
     law or governmental rule, regulation or order) or (2) any other
     circumstances affecting Bank or Lender or the interbank Eurodollar market
     or the position of Bank or Lender in such market (such as, for example, but
     not limited to, official reserve requirements required by Regulation D of
     the Board of Governors of the Federal Reserve System to the extent not
     given effect in the Eurodollar Rate), the Eurodollar Rate shall not
     represent the effective pricing to Lender for Dollar deposits of comparable
     amounts for the relevant period;

then, and in any such event, the right of the Borrower to request application of
the Eurodollar Rate to some or all of the Loans shall be suspended until the
Lender shall notify the Borrower that the circumstances causing such suspension
no longer exist, and such Loans shall be Reference Rate Loans.

          (e)  Illegality.  In the event that on any date Lender shall have
               ----------                                                  
reasonably determined (which determination shall, absent manifest error, be
final and conclusive and binding 

                                       23
<PAGE>
 
upon all parties) that the making of, conversion into, or the continuation of,
Lender's Eurodollar Rate Loans has become unlawful as the result of compliance
by Lender or Bank in good faith with any law, governmental rule, regulation or
order (whether or not having the force of law and whether or not failure to
comply therewith would be unlawful), then, and in any such event, Lender shall
promptly give notice (by telephone confirmed in writing) to the Borrower of such
determination. In such case and except as provided in Section 3.3(f), the
                                                      -------------- 
obligation of Lender to make or maintain any Eurodollar Rate Loans during any
such period shall be terminated at the earlier of the termination of the
Interest Period then in effect or when required by law, and the Borrower shall,
no later than the earlier of the termination of the Interest Period in effect at
the time any such determination pursuant to this Section 3.3(e) is made, or when
                                                 --------------
required by law, repay the Eurodollar Rate Loans, together with all interest
accrued thereon.

          (f)  Options of the Borrower. In lieu of prepaying the Eurodollar Rate
               -----------------------
Loans as required by Section 3.3(e), the Borrower may exercise either of the
following options:

               (i)  Upon written notice to the Lender, the Borrower may release
     Lender from its obligations to make or maintain Loans as Eurodollar Rate
     Loans and in such event, the Borrower shall, at the end of the then current
     Interest Period (or at such earlier time as prepayment is otherwise
     required), convert all of the Eurodollar Rate Loans into Reference Rate
     Loans in the manner contemplated by Section 3.2, but without satisfying the
                                         -----------
     advance notice requirements therein; or

               (ii) The Borrower may, by giving notice (by telephone confirmed
     immediately by telecopy) to Lender require Lender to continue to maintain
     its outstanding Reference Rate Loans as Reference Rate Loans, but without
     satisfying the advance notice requirements set forth in such Section 3.2.
                                                                  ----------- 

          (g)  Compensation.  In addition to such amounts as are required to be
               ------------                                                    
paid by the Borrower pursuant to the other Sections of this Article 3, the
Borrower agrees to compensate the Lender for all expenses and liabilities,
including, without limitation, any loss or expense incurred by Lender by reason
of the liquidation or reemployment of deposits or other funds acquired by Lender
to fund or maintain the Lender's Eurodollar Rate Loans to the Borrower, which
Lender sustains (i) if due to the fault of the Borrower a funding of any
Eurodollar Rate Loans does not occur on a date specified therefor by Borrower in
a telephonic or written request for borrowing or conversion/continuation, or a
successive Interest Period does not commence after notice therefor is given
pursuant to Section 3.2, (ii) if any voluntary or mandatory prepayment of any
            -----------                                                      
Eurodollar Rate Loans occurs for any reason on a date which is not the last
scheduled day of an Interest Period, or (iii) as a consequence of any other
                                     --                                    
failure by the Borrower to repay Eurodollar Rate Loans when required by the
terms of this Agreement.

          (h)  Quotation of Eurodollar Rate.  Anything herein to the contrary
               ----------------------------                                  
notwithstanding, if on any Eurodollar Interest Rate Determination Date no
Eurodollar Rate is available by reason of the failure of Bank to be offered
quotations in accordance with the definition of "Eurodollar Base Rate," the
Lender shall give the Borrower prompt notice thereof and (i) any Eurodollar Rate
Loan requested to be made at the Eurodollar Rate to be determined on any
Eurodollar Interest Rate Determination Date shall be made as a Reference Rate
Loan, and (ii) any 

                                       24
<PAGE>
 
notice given by the Borrower to convert any Loans into or to continue any Loans
as Eurodollar Rate Loans at the Eurodollar Rate to be determined on any such
Eurodollar Interest Rate Determination Date shall be ineffective.

          (i)  Eurodollar Rate Taxes.  The Borrower agrees that it will pay,
               ---------------------                                        
prior to the date on which penalties attach thereto, all present and future
income, stamp and other taxes, levies, or costs and charges whatsoever imposed,
assessed, levied or collected on or from the Lender on or in respect of the
Borrower's Loans from the Lender solely as a result of the interest rate being
determined by reference to the Eurodollar Rate and/or the provisions of this
Agreement relating to the Eurodollar Rate and/or the recording, registration,
notarization or other formalization of any of the foregoing and/or any payments
of principal, interest or other amounts made on or in respect of the Loans from
the Lender when the interest rate is determined by reference to the Eurodollar
Rate (all such taxes, levies, cost and charges being herein collectively called
"Eurodollar Rate Taxes"); provided, however, that Eurodollar Rate Taxes shall
 ---------------------    --------  -------                                  
not include taxes imposed on or measured by the overall net income of the Lender
by the United States of America or any political subdivision or taxing authority
thereof or therein, or taxes on or measured by the overall net income by any
foreign branch or subsidiary of the Lender by any foreign country or subdivision
thereof in which that branch or subsidiary is doing business.  Promptly after
the date on which payment of any such Eurodollar Rate Tax is due pursuant to
applicable law, the Borrower will, at the request of the Lender, furnish to the
Lender evidence, in form and substance satisfactory to the Lender, that the
Borrower has met its obligation under this Section 3.3(i), an addition, the
                                           --------------                  
Borrower will indemnify the Lender against, and reimburse Lender on demand for,
any Eurodollar Rate Taxes for which the Lender is or may be liable by reason of
the making or maintenance of any Eurodollar Rate Loans hereunder, as determined
by the Lender in its discretion exercised in good faith and pursuant to
standards of commercial reasonableness.  The Lender shall provide Borrower with
appropriate receipts for any payments or reimbursements made by Borrower
pursuant to this Section 3.3(i).
                 -------------- 

          (j)  Booking of Eurodollar Rate Loans.  The Lender may make, carry or
               --------------------------------                                
transfer Eurodollar Rate Loans at, to, or for the account of, any of its branch
offices or the office of any of its Affiliates.

          (k)  Increased Costs. If, due to either (i) the introduction of or any
               ---------------
change (other than any change by way of imposition or increase of reserve
requirements included in the Eurodollar Reserve Percentage) in or in the
interpretation of any law or regulation or (ii) the compliance with any
guideline or request from any central bank or other Public Authority (whether or
not having the force of law), there shall be any increase in the cost to the
Lender of agreeing to make or making, funding or maintaining Eurodollar Rate
Loans, then the Borrower agrees that it shall, from time to time, upon demand by
the Lender in writing to the Borrower, within sixty (60) days from the date of
such increased cost, pay to the Lender additional amounts sufficient to
compensate the Lender for such increased cost relating to the outstanding
Eurodollar Rate Loans made to the Borrower. A certificate as to the amount of
such increased cost and the method of determination thereof, submitted to the
Borrower by the Lender, shall be rebuttably presumptive evidence of the
correctness of such amount. Notwithstanding the above, the Lender shall promptly
advise Borrower of any increased costs covered by this paragraph (k) of which
Lender is aware that have been made or which are proposed to be made which may
require the Borrower to be required to pay the increased cost 

                                       25

under this paragraph (k) prior to or at the time that Borrower requests
additional Eurodollar Rate Loans.

          3.4  Maximum Interest Rate.
               --------------------- 

          (a)  Notwithstanding the foregoing provisions of Sections 3.1 through
                                                           --------------------
3.3 regarding the rates of interest applicable to the Loans, if at any time the
- ---                                                                            
amount of such interest computed on the basis of the Applicable Interest Rate
would exceed the amount of such interest computed upon the basis of the maximum
rate of interest permitted by applicable state or federal law in effect from
time to time hereafter, after taking into account, to the extent required by
applicable law, any and all fees, payments, charges and calculations provided
for in this Agreement or in any other agreement between Borrower and Lender (the
"Maximum Legal Rate"), the interest payable under this Agreement shall be
 ------------------                                                      
computed upon the basis of the Maximum Legal Rate, but any subsequent reduction
in the Reference Rate or the Eurodollar Rate shall not reduce such interest
thereafter payable hereunder below the amount computed on the basis of the
Maximum Legal Rate until the aggregate amount of such interest accrued and
payable under this Agreement equals the total amount of interest which would
have accrued if such interest had been at all times computed solely on the basis
of the Applicable Interest Rate.

          (b)  No agreements, conditions, provisions or stipulations contained
in this Agreement or any other instrument, document or agreement between the
Borrower and the Lender or default of the Borrower, or the exercise by the
Lender of the right to accelerate the payment of the maturity of principal and
interest, or to exercise any option whatsoever contained in this Agreement or
any other agreement between the Borrower and the Lender, or the arising of any
contingency whatsoever, shall entitle the Lender to collect, in any event,
interest exceeding the Maximum Legal Rate and in no event shall the Borrower be
obligated to pay interest exceeding such Maximum Legal Rate and all agreements,
conditions or stipulations, if any, which may in any event or contingency
whatsoever operate to bind, obligate or compel the Borrower to pay a rate of
interest exceeding the Maximum Legal Rate, shall be without binding force or
effect, at law or in equity, to the extent only of the excess of interest over
such Maximum Legal Rate. In the event any interest is charged in excess of the
Maximum Legal Rate ("Excess"), the Borrower acknowledges and stipulates that any
                     ------
such charge shall be the result of an accidental and bona fide error, and such
                                                     ---- ----
Excess shall be, first, applied to reduce the principal then unpaid hereunder;
second, applied to reduce the Obligations; and third, returned to the Borrower,
it being the intention of the parties hereto not to enter at any time into a
usurious or otherwise illegal relationship. The Borrower recognizes that, with
fluctuations in the Applicable Interest Rate and the Maximum Legal Rate, such an
unintentional result could inadvertently occur. By the execution of this
Agreement, the Borrower covenants that (i) the credit or return of any Excess
shall constitute the acceptance by the Borrower of such Excess, and (ii) the
Borrower shall not seek or pursue any other remedy, legal or equitable, against
Lender, based in whole or in part upon the charging or receiving of any interest
in excess of the maximum authorized by applicable law. For the purpose of
determining whether or not any Excess has been contracted for, charged or
received by Lender, all interest at any time contracted for, charged or received
by the Lender in connection with this Agreement shall be amortized, prorated,
allocated and spread in equal parts during the entire term of this Agreement.

into every document or communication relating to the Obligations which sets
forth or prescribes any account, right or claim or alleged account, right or
claim of the Lender with respect to the Borrower (or any other obligor in
respect of Obligations), whether or not any provision of Section 3.4 is referred
                                                         -----------            
to therein.  All such documents and communications and all figures set forth
therein shall, for the sole purpose of computing the extent of the liabilities
and obligations of the Borrower (or other obligor) asserted by the Lender
thereunder, be automatically recomputed by any Borrower or obligor, and by any
court considering the same, to give effect to the adjustments or credits
required by Section 3.4.
            ----------- 

          (d)  If the applicable state or federal law is amended in the future
to allow a greater rate of interest to be charged under this Agreement or any
other Loan Documents than is presently allowed by applicable state or federal
law, then the limitation of interest under Section 3.4 shall be increased to the
                                           ----------- 
maximum rate of interest allowed by applicable state or federal law as amended,
which increase shall be effective hereunder on the effective date of such
amendment, and all interest charges owing to the Lender by reason thereof shall
be payable upon demand.

          3.5  Capital Adequacy.  If as a result of any regulatory change
               ----------------                                          
directly or indirectly affecting Lender or any of Lender's affiliated companies
there shall be imposed, modified or deemed applicable any tax, reserve, special
deposit, minimum capital, capital ratio, or similar requirement against or with
respect to or measured by reference to loans made or to be made to Borrower
hereunder, or to Letters of Credit issued on behalf of Borrower pursuant to the
Letter of Credit Agreement, and the result shall be to increase the cost to
Lender or to any of Lender's affiliated companies of making or maintaining any
Revolving Loan or Letter of Credit hereunder, or reduce any amount receivable in
respect of any such Revolving Loan and which increase in cost, or reduction in
amount receivable, shall be the result of Lender's or Lender's affiliated
company's reasonable allocation among all affected customers of the aggregate of
such increases or reductions resulting from such event, then, within ten (10)
days after receipt by Borrower of a certificate from Lender containing the
information described in this Section 3.5 which shall be delivered to Borrower,
                              -----------                                      
Borrower agrees from time to time to pay Lender such additional amounts as shall
be sufficient to compensate Lender or any of Lender's affiliated companies for
such increased costs or reductions in amounts which Lender determines in
Lender's reasonable discretion are material.  Notwithstanding the foregoing, all
such amounts shall be subject to the provisions of Section 3.4.  The certificate
                                                   -----------                  
requesting compensation under this Section 3.5 shall identify the regulatory
                                   -----------                              
change which has occurred, the requirements which have been imposed, modified or
deemed applicable, the amount of such additional cost or reduction in the amount
receivable and the way in which such amount has been calculated.

          3.6  Unused Line Fee.  For every month during the term of this
               ---------------                                          
Agreement, the Borrower shall pay the Lender a fee (the "Unused Line Fee") in an
                                                         ---------------        
amount equal to one-half of one percent (.50%) per annum, multiplied by the
                                                          -------------    
amount by which (a) the Maximum Borrowing Commitment exceeds (b) the average
closing daily unpaid balance of all revolving loans and all issued but undrawn
letters of credit under all of the LSB-Related Loan Agreements during such
month, with the unpaid balance calculated for this purpose by applying payments
immediately upon receipt.  Such a fee, if any, shall be calculated on the basis
of a year of three hundred sixty (360) days and actual days elapsed, and shall
be payable to the Lender on the first day of each month prior to 

                                       27
<PAGE>
 
the termination of this Agreement commencing January 1, 1998 and on the
termination of this Agreement, with respect to the prior month or portion
thereof.

     4.   PAYMENTS AND PREPAYMENTS.
          ------------------------ 

          4.1  Revolving Loans.  The Borrower shall repay the outstanding
               ---------------                                           
principal balance of the Revolving Loans, plus all accrued but unpaid interest
thereon, upon the termination of this Agreement.  In addition, the Borrower
shall pay to the Lender, on demand, the amount by which the unpaid principal
balance of the Revolving Loans at any time exceeds the Availability at such time
(with Availability for this purpose determined as if the amount of the Revolving
Loans were zero).

          4.2  Place and Form of Payments: Extension of Time.  All payments of
               ---------------------------------------------                  
principal, interest, and other sums due to the Lender shall be made at the
Lender's address set forth in Section 13.10.  Except for Proceeds received
                              -------------                               
directly by the Lender, all such payments shall be made in immediately available
funds.  If any payment of principal, interest, or other sum to be made hereunder
becomes due and payable on a day other than a Business Day, the due date of such
payment shall be extended to the next succeeding Business Day and interest
thereon shall be payable at the applicable interest rate during such extension.

          4.3  Apportionment, Application and Reversal of Payments.  Except as
               ---------------------------------------------------            
otherwise expressly provided hereunder, the Lender shall determine in its
discretion the order and manner in which proceeds and other payments that the
Lender receives are applied to the Revolving Loans, interest thereon, and the
other Obligations, and the Borrower hereby irrevocably waives the right to
direct the application of any payment or proceeds; provided, however, unless so
                                                   --------  -------           
directed by the Borrower, the Lender shall not apply any such payments which it
receives to any Eurodollar Rate Loan, except:  (a) on the expiration date of the
Interest Period applicable to any such Eurodollar Rate Loan; or (b) in the
event, and only to the extent, that there are not outstanding Reference Rate
Loans. Following an Event of Default that is continuing, the Lender shall have
the continuing and exclusive right to apply and reverse and reapply any and all
such proceeds and payments to any portion of the Obligations subject to the
terms of this Section 4.3 and the Borrower's right to direct prepayments of
              -----------                                                  
Eurodollar Rate Loans.

          4.4  INDEMNITY FOR RETURNED PAYMENTS.  IF AFTER RECEIPT OF ANY PAYMENT
               -------------------------------                                  
OF, OR PROCEEDS APPLIED TO THE PAYMENT OF, ALL OR ANY PART OF THE OBLIGATIONS,
THE LENDER IS FOR ANY REASON REQUIRED TO SURRENDER SUCH PAYMENT OR PROCEEDS TO
ANY PERSON, BECAUSE SUCH PAYMENT OR PROCEEDS IS INVALIDATED, DECLARED
FRAUDULENT, SET ASIDE, DETERMINED TO BE VOID OR VOIDABLE AS A PREFERENCE, OR A
DIVERSION OF TRUST FUNDS, OR FOR ANY OTHER REASON, THEN:  THE OBLIGATIONS OR
PART THEREOF INTENDED TO BE SATISFIED SHALL BE REVIVED AND CONTINUE AND THIS
AGREEMENT SHALL CONTINUE IN FULL FORCE AS IF SUCH PAYMENT OR PROCEEDS HAD NOT
BEEN RECEIVED BY THE LENDER AND THE BORROWER SHALL BE LIABLE TO PAY TO THE
LENDER, AND HEREBY DOES INDEMNIFY THE LENDER AND HOLD THE LENDER HARMLESS FOR
THE AMOUNT OF SUCH PAYMENT OR PROCEEDS SURRENDERED.  The provisions of this
Section 4.4 shall be and remain effective notwithstanding any contrary action
- -----------                                                                  
which may have been taken by the Lender in 

                                       28
<PAGE>
 
reliance upon such payment or Proceeds, and any such contrary action so taken
shall be without prejudice to the Lender's rights under this Agreement and shall
be deemed to have been conditioned upon such payment or Proceeds having become
final and irrevocable. The provisions of this Section 4.4 shall survive the
                                              -----------
termination of this Agreement.


     5.   LENDER'S BOOKS AND RECORDS:  MONTHLY STATEMENTS.  The Borrower agrees
          -----------------------------------------------                      
that the Lender's books and records showing the Obligations and the transactions
pursuant to this Agreement and the other Loan Documents shall be admissible in
any action or proceeding arising therefrom irrespective of whether any
Obligation is also evidenced by a promissory note or other instrument, and shall
constitute presumptive proof thereof until such time as Borrower has reviewed
the monthly statement as hereinafter provided.  The Lender will provide to the
Borrower a monthly statement of Loans, payments, and other transactions pursuant
to this Agreement.  Such statement shall be deemed correct, accurate, and
binding on the Borrower and as an account stated and shall constitute prima
facie proof thereof (except for reversals and reapplications of payments made as
provided in Section 4.3 and corrections of errors discovered by the Lender),
            -----------                                                     
unless the Borrower notifies the Lender in writing to the contrary within thirty
(30) days after such statement is rendered.  In the event a timely written
notice of objections is given by the Borrower, only the items to which exception
is expressly made will be considered to be disputed by the Borrower.

     6.   COLLATERAL.
          ---------- 

          6.1  Grant of Security Interest.
               -------------------------- 

          (a)  As security for the Obligations, each Borrower hereby grants to
the Lender a continuing security interest in, lien on, and assignment of: (i)
all Receivables, Inventory, Proprietary Rights, and Proceeds, wherever located
and whether now existing or hereafter arising or acquired; (ii) all moneys,
securities and other property and the Proceeds thereof, now or hereafter held or
received by, or in transit to, the Lender from or for the Borrower, whether for
safekeeping, pledge, custody, transmission, collection or otherwise, including,
without limitation, all of the Borrower's deposit accounts, credits and balances
with the Lender and all claims of the Borrower against the Lender at any time
existing; (iii) all of Borrower's deposit accounts containing Collateral with
any financial institutions with which Borrower maintains deposits; and (iv) all
books, records, ledger cards, data processing records, computer software and
other property and general intangibles at any time evidencing or relating to the
Receivables, Inventory, Proprietary Rights, Proceeds, and other property
referred to above (all of the foregoing, together with all other property in
which Lender may at any time be granted a Lien, being herein collectively
referred to as the "Collateral").  The Lender shall have all of the rights of a
                    ----------                                                 
secured party with respect to the Collateral under the UCC and other applicable
laws.

          (b)  All Obligations shall constitute a single loan secured by all of
the Collateral. The Lender may, in its sole discretion, (i) exchange, waive, or
release any of the Collateral, (ii) after the occurrence of an Event of Default
that is continuing, apply Collateral and direct the order or manner of sale
thereof as the Lender may determine, and (iii) after the occurrence of an Event
of Default that is continuing, settle, compromise, collect, or otherwise
liquidate any Collateral in any 

                                       29
<PAGE>
 
manner, all without affecting the Obligations or the Lender's right to take any
other action with respect to any other Collateral.

          6.2  Perfection and Protection of Security Interest.  Each Borrower
               ----------------------------------------------                
shall, at its expense, perform all steps requested by the Lender at any time to
perfect, maintain, protect, and enforce the Security Interest in the Collateral
including, without limitation: (a) executing and recording of the Patent and
Trademark Assignments and executing and filing financing or continuation
statements, and amendments thereof, relating to the Collateral in form and
substance satisfactory to the Lender; (b) delivering to the Lender, upon
Lender's request therefor, the originals of all instruments, documents, and
chattel paper, and all other Collateral of which the Lender determines it should
have physical possession in order to perfect and protect the Security Interest
therein, duly endorsed or assigned to the Lender without restriction; (c)
delivering to the Lender warehouse receipts covering any portion of the
Collateral located in warehouses and for which warehouse receipts are issued;
(d) after an Event of Default that is continuing, placing notations on the
Borrower's books of account to disclose the Security Interest; (e) delivering to
the Lender, upon Lender's request therefor, all letters of credit on which the
Borrower is a named beneficiary; (f) after an Event of Default that is
continuing, transferring Inventory to warehouses designated by the Lender; and
(g) taking such other steps as are deemed necessary by the Lender to maintain
the Security Interest. The Lender may file, without the Borrower's signature,
one or more financing statements disclosing the Security Interest. The Borrower
agrees that a carbon, photographic, photostatic, or other reproduction of this
Agreement or of a financing statement is sufficient as a financing statement. If
any Collateral is at any time in the possession or control of any warehouseman,
bailee or any of the Borrower's agents or processors, then the Borrower shall
notify the Lender thereof and shall notify such Person of the Security Interest
in such Collateral and, upon the Lender's request following an Event of Default
that is continuing, instruct such Person to hold all such Collateral for the
Lender's account subject to the Lender's instructions. If at any time any
Collateral is located on any premises that are not owned by the Borrower, then
the Borrower shall obtain written waivers, in form and substance reasonably
satisfactory to the Lender, of all present and future Liens to which the owner
or lessor of such premises may be entitled to assert against the Collateral.
From time to time, the Borrower shall, upon Lender's request, execute and
deliver confirmatory written instruments pledging to the Lender the Collateral,
but the Borrower's failure to do so shall not affect or limit the Security
Interest. So long as this Agreement is in effect and until all Obligations have
been fully satisfied, the Security Interest shall continue in full force and
effect in all Collateral (whether or not deemed eligible for the purpose of
calculating the Availability or as the basis for any advance, loan, or other
financial accommodation). Upon termination of this Agreement and payment of all
Obligations, the Lender shall release all Security Interests held by the Lender.

          6.3  Location of Collateral.  Each Borrower represents and warrants to
               ----------------------                                           
the Lender that: (a) Exhibit D hereto is a correct and complete List of the
                     ---------                                             
Borrower's chief executive office, the location of its books and records, the
locations of the Collateral, and the locations of all of its other places of
business; and (b) Exhibit H correctly identifies any of such facilities and
                  ---------                                                
locations that are not owned by the Borrower and sets forth the names of the
owners and lessors of, and, to the best of the Borrower's knowledge, the holders
of any mortgages on such facilities and locations.  Except for Inventory that is
consigned by a Borrower to a customer or warehouse, the Borrower agrees that it
will not maintain any Collateral at any location other than those listed on
Exhibit D, and it will not 
- ---------

                                       30
<PAGE>
 
otherwise change or add to any of such locations, unless it gives the Lender at
least thirty (30) days prior written notice and executes such financing
statements and other documents that the Lender requests in connection therewith.

          6.4   Title to, Liens on, and Sale and Use of Collateral.  Each
                --------------------------------------------------       
Borrower represents and warrants to the Lender that: (a) all Collateral is and
will continue to be owned by the Borrower free and clear of all Liens
whatsoever, except for the Security Interest and other Permitted Liens; (b) the
Security Interest will not be subject to any prior Lien except the Permitted
Liens; (c) the Borrower will use, store, and maintain the Collateral with all
reasonable care and will use the Collateral for lawful purposes only; and (d)
the Borrower will not, without the Lender's prior written approval, sell, or
dispose of or permit the sale or disposition of any Collateral, except for (i)
sales of Inventory in the ordinary course of business, and (ii) as otherwise
provided or allowed by this Agreement or any of the other Loan Documents. The
inclusion of Proceeds in the Collateral shall not be deemed the Lender's consent
to any sale or other disposition of the Collateral except as expressly permitted
herein.

          6.5   Appraisals. Following the occurrence of an Event of Default that
                ----------
is continuing, each Borrower shall, at the request of the Lender, provide the
Lender, at the Borrower's expense, with appraisals or updates thereof of any or
all of the Collateral from an appraiser satisfactory to the Lender.

          6.6   Access and Examination.  The Lender may at all reasonable times
                ----------------------                                         
have access to, examine, audit, make extracts from and inspect the Borrower's
records, files, and books of account and the Collateral and may discuss the
Borrower's affairs with the Borrower's officers and management.  The Borrower
will deliver to the Lender any instrument necessary for the Lender to obtain
records from any service bureau maintaining records for the Borrower.  The
Lender may, at any time when an Event of Default exists and at the Borrower's
expense, make copies of all of the Borrower's books and records, or require the
Borrower to deliver such copies to the Lender.  After the occurrence of an Event
of Default that is continuing, the Lender may, without expense to the Lender,
use such of the Borrower's personnel, supplies, and premises as may be
reasonably necessary for maintaining or enforcing the Security Interest.  Lender
shall have the right, at any time, in Lender's name or in the name of a nominee
of the Lender, to verify the validity, amount or any other matter relating to
the Accounts, by mail, telephone, or otherwise.

          6.7   Insurance.  The Borrower shall insure the Collateral and its
                ---------                                                   
Equipment against loss or damage by fire with extended coverage, theft,
burglary, pilferage, loss in transit, and such other hazards as the Lender shall
specify, in amounts, under policies and by insurers acceptable to the Lender.
Borrower shall also maintain flood insurance, in the event of a designation of
the area in which any Real Property is located as "flood prone" or a "flood risk
area," as defined by the Flood Disaster Protection Act of 1973, in an amount to
be reasonably determined by Lender, and shall comply with the additional
requirements of the National Flood Insurance Program as set forth therein. The
Borrower shall cause the Lender to be named in each such policy as secured party
of the Inventory that constitutes part of the Collateral and loss payee or
additional insured, in a manner acceptable to the Lender, as to the Collateral.
Each policy of insurance shall contain a clause or endorsement requiring the
insurer to give not less than thirty (30) days prior written notice to the
Lender in the event of cancellation of the policy for any reason whatsoever and
a clause or 

                                       31
<PAGE>
 
endorsement stating that the interest of the Lender shall not be impaired or
invalidated by any act or neglect of the Borrower or the owner of any premises
where Collateral is located nor by the use of such premises for purposes more
hazardous than are permitted by such policy. All premiums for such insurance
shall be paid by the Borrower when due, and certificates of insurance and, if
requested, photocopies of the policies shall be delivered to the Lender. If the
Borrower fails to procure such insurance or to pay the premiums therefor when
due, the Lender may (but shall not be required to) do so and charge the costs
thereof to the Borrower's loan account. After becoming aware of any loss, damage
or destruction to Collateral, the Borrower shall promptly notify the Lender of
any such loss, damage, or destruction that exceeds $200,000, whether or not
covered by insurance. The Lender is hereby authorized to collect all insurance
proceeds directly following the occurrence of an Event of Default that is
continuing. After deducting from such proceeds the expenses, if any, incurred by
Lender in the collection or handling thereof, if an Event of Default has
occurred and is continuing, the Lender may apply such proceeds to the reduction
of the Obligations, in such order as Lender determines, or at the Lender's
option may permit or require the Borrower to use such money, or any part
thereof, to replace, repair, restore or rebuild the Collateral in a diligent and
expeditious manner with materials and workmanship of substantially the same
quality as existed before the loss, damage or destruction. If no Event of
Default has occurred and is continuing, Lender hereby authorizes Borrower to
collect all such insurance proceeds and to use such money, or any part thereof,
to replace, repair, restore or rebuild the Collateral in a diligent and
expeditious manner with materials and workmanship of substantially the same
quality as existed before the loss, damage or destruction.

          6.8   Collateral Reporting.  The Borrower will provide the Lender with
                --------------------

Lender:  (a) on a daily basis, a schedule of Accounts created since the last

detailed agings of Accounts aged by due date and by invoice date; (c) no later

of Accounts balances per the aging to the general ledger accounts receivable
balance and to the financial statements provided to Lender under Section 7.2(c);

(d) no later than twenty (20) days after the last day of each month, monthly

to Lender under Section 7.2(c); (f) upon request, copies of invoices, credit
                --------------                                              
memos, shipping and delivery documents, purchase orders; (g) such other reports
as to the Collateral as the Lender shall request from time to time; and (h)
certificates of an officer of the Borrower certifying as to the foregoing.  If
any of the Borrower's records or reports of the Collateral are prepared by an
accounting service or other agent, the Borrower hereby authorizes such service
or agent to deliver such records, reports, and related documents to the Lender.

          6.9   Accounts.  (a) Each Borrower hereby represents and warrants to
                --------                                                      
the Lender that: (i) each existing Account represents, and each future Account
will represent, a bona fide sale or lease and delivery of goods by the Borrower,
                  ---- ----

Borrower's business; (ii) each existing Account is, and each future Account will

described in each invoice will have been performed, except where the Account
Debtor has previously agreed in writing to accept billings for such goods.


          (b)   The Borrower shall not re-date any invoice or sale or make sales
on extended dating beyond that customary in the Borrower's business or extend or
modify any Account which alters its eligibility status, or, with respect to
ineligible Accounts, which are inconsistent with prudent business practice and
industry standards.  If the Borrower becomes aware of any matter adversely
affecting any Account in an amount in excess of $100,000, including information
regarding the Account Debtor's creditworthiness, the Borrower will promptly so
advise the Lender.

          (c)   The Borrower shall not accept any note or other instrument
(except a check or other instrument for the immediate payment of money) with
respect to any Eligible Account without the Lender's written consent. If the
Lender consents to the acceptance of any such instrument, it shall be considered
as evidence of the Account and not payment thereof and the Borrower will upon
Lender's request, promptly deliver such instrument to the Lender appropriately
endorsed. Regardless of the form of presentment, demand, notice of dishonor,
protest, and notice of protest with respect thereto, the Borrower will remain
liable thereon until such instrument is paid in full.

          (d)   The Borrower shall notify the Lender promptly of all disputes
and claims with an Account Debtor relating to an Eligible Account that exceeds
$100,000 and when no Event of Default exists hereunder, may settle or adjust
them at no expense to the Lender, but no discount, credit or allowance in excess
of $100,000 shall be granted to any Account Debtor without the Lender's consent,
except for discounts, credits and allowances made or given in the ordinary
course of the Borrower's business. The Borrower shall send the Lender a copy of
each credit memorandum in excess of $100,000 as soon as issued. The Lender may,
at all times when an Event of Default exists hereunder, settle or adjust
disputes and claims directly with Account Debtors for amounts and upon terms
which the Lender considers advisable and, in all cases, the Lender will credit
the Borrower's loan account with only the net amounts received by the Lender in
payment of any Accounts.

          6.10  Collection of Accounts. (a) Until the occurrence of an Event of
                ---------------------- 
Default that is continuing, the Borrower shall collect all Accounts, shall
receive all payments relating to Accounts, and shall promptly deposit all such
collections into a Payment Account established for the account of the Borrower
at a bank acceptable to the Borrower and the Lender. All collections relating to
Accounts received in any such Payment Account or directly by the Borrower or the
Lender, and all funds in any Payment Account or other account to which such
collections are deposited, shall be the sole property of the Lender and subject
to the Lender's sole control. After the occurrence of an Event of Default that
is continuing, the Lender may, at any time, notify obligors that the Accounts
have been assigned to the Lender and of the Security Interest therein, and may
collect

                                       33
<PAGE>
 
them directly and charge the collection costs and expenses to the Borrower's
loan account. After the occurrence of an Event of Default that is continuing,
the Borrower, at Lender's request, shall execute and deliver to the Lender such
documents as the Lender shall require to grant the Lender access to any post
office box in which collections of Accounts are received.

          (a)   If sales of Inventory are made for cash, the Borrower shall
immediately deliver to the Lender the identical checks, cash, or other forms of
payment which the Borrower receives.

          (b)   All payments received by the Lender on account of Accounts or as
Proceeds of other Collateral will be the Lender's sole property and will be
credited to the Borrower's loan account (conditional upon final collection)
after allowing one (1) Business Day for collection.

          (c)   In the event the Borrower repays all of the Obligations upon the
termination of this Agreement, other than through the Lender's receipt of
payments on account of Accounts or Proceeds of other Collateral, such payment
will be credited (conditional upon final collection) to the Borrower's loan
account one (1) Business Day after the Lender's receipt thereof.

          6.11  Inventory.  Each Borrower represents and warrants to the
                ---------                                               
Lender that all of the Inventory is and will be held for sale or lease, or to be
furnished in connection with the rendition of services, in the ordinary course
of the Borrower's business, and is and will be fit for such purposes. The
Borrower will keep the Inventory in good and marketable condition, at its own
expense.  The Borrower agrees that all Inventory produced by the Borrower in the
United States will be produced in accordance with the Federal Fair Labor
Standards Act of 1938.  The Borrower will conduct a physical count of the
Inventory at least once per Fiscal Year, except as otherwise agreed to between
the Lender and the Borrower, and will, upon request of the Lender, supply the
Lender with a copy of such count accompanied by a report of the value of such
Inventory (valued at the lower or cost, on a first-in, first-out basis, or
market value).  The Borrower will not, without the Lender's written consent,
sell any Inventory on a bill and hold basis (except as provided in subsection
(xiii) of the definition of Eligible Accounts set forth in this Agreement),
guaranteed sale, sale and return, sale on approval, consignment, or other
repurchase or return basis.

          6.12  Documents and Instruments. Each Borrower represents and warrants
                -------------------------
to the Lender that: (a) all Documents and Instruments describing, evidencing, or
constituting Collateral, and all signatures and endorsements thereon, are and
will be complete, valid, and genuine and (b) all goods evidenced by such
Documents and Instruments were, at the time of their sale, owned by the Borrower
free and clear of all Liens other than Permitted Liens.

          6.13  Right to Cure. The Lender may in its sole discretion pay any
                -------------
amount or do any act required of the Borrower hereunder in order to preserve,
protect, maintain or enforce the Obligations, the Collateral or the Security
Interest, and which the Borrower fails to pay or do, including, without
limitation, payment of any judgment against the Borrower, any insurance premium,
any warehouse charge, processing charge, any landlord's claim, and any other
Lien upon the Collateral. All payments that the Lender makes under this Section
                                                                        -------
6.13 and all out-of-pocket costs and expenses that the Lender pays or incurs in
- ----
connection with any action, taken by it hereunder shall be charged to the
Borrower's loan account; provided that Lender will make a good

                                       34
<PAGE>
 
faith effort to notify the Borrower and provide the Borrower with a written,
itemized invoice covering such charge. Any payment made or other action taken by
the Lender under this Section 6.13 shall be without prejudice to any right
Lender may have to assert an Event of Default hereunder and to proceed
accordingly.

          6.14  Power of Attorney. Each Borrower appoints the Lender and the
                -----------------
Lender's designees as the Borrower's attorney, with power: (a) to endorse the
Borrower's name on any checks, notes, acceptances, money orders, or other forms
of payment or security that come into the Lender's possession; (b) to sign the
Borrower's name on any invoice, bill of lading, or other document of title
relating to any Collateral, on drafts against customers, on assignments of
Accounts, on notices of assignment, financing statements and other public
records and on verifications of Accounts to Account Debtors; (c) to notify the
post office authorities, when an Event of Default exists, to change the address
for delivery of the Borrower's mail to an address designated by the Lender and
to receive, open and dispose of all mail addressed to the Borrower; (d) to send
requests for verification of Accounts to Account Debtors; and (e) to do all
things necessary to carry out this Agreement. The Borrower ratifies and approves
all acts of such attorney. Neither the Lender nor the attorney will be liable
for any acts or omissions or for any error of judgment or mistake of fact or
law. This power, being coupled with an interest, is irrevocable until this
Agreement has been terminated and the Obligations have been fully satisfied.

          6.15  Lender's Rights, Duties, and Liabilities. Each Borrower assumes
                ----------------------------------------
all responsibility and liability arising from or relating to the use, sale or
other disposition of the Collateral. Neither the Lender nor any of its officers,
directors, employees, and agents shall be liable or responsible in any way for
the safekeeping of any of the Collateral, or for any act or failure to act with
respect to the Collateral, or for any loss or damage thereto, or for any
diminution in the value thereof, or for any act of default by any warehouseman,
carrier, forwarding agency or, other person whomsoever, all of which shall be at
the Borrower's sole risk. The Obligations shall not be affected by any failure
of the Lender to take any steps to perfect the Security Interest or to collect
or realize upon the Collateral, nor shall loss of or damage to the Collateral
release the Borrower from any of the Obligations. After the occurrence of an
Event of Default that has not been cured or otherwise waived by Lender, the
Lender may (but shall not be required to), without notice to or consent from the
Borrower, sue upon or otherwise collect, extend the time for payment of, modify
or amend the terms of, compromise or settle for cash or credit, grant other
indulgences, extensions, renewals, compositions, or releases, and take or omit
to take other action with respect to the Collateral, any security therefor, any
agreement relating thereto, any insurance applicable thereto, or any Person
liable directly or indirectly in connection with any of the foregoing, without
discharging or otherwise affecting the liability of the Borrower for the
Obligations.

          6.16  Release of Collateral and Borrower.  Upon payment in full of
                ----------------------------------                          
all Obligations, Lender shall immediately release its Security Interest in and
to all of the Collateral.

          -------------------------------------- 

          Each Borrower continuously warrants and represents to the Lender, at
all times during the term of this Agreement and until all Obligations have been
satisfied, that, except as hereafter disclosed to and accepted by the Lender in
writing in the exercise of its reasonable discretion:

          8.1   Authorization, Validity, and Enforceability of this Agreement
                -------------------------------------------------------------

taken all necessary corporate action to authorize its execution, delivery, and
performance of this Agreement and the other Loan Documents. No consent,
approval, or authorization of, or filing with, any Public Authority, and no
consent of, any other Person, is required in connection with the Borrower's

and the other Loan Documents have been duly executed and delivered by the
Borrower and constitute the legal, valid and binding obligation of the Borrower,
enforceable against it in accordance with its terms without defense, setoff, or
counterclaim. The Borrower's execution, delivery, and performance of this

the creation or imposition of any Lien upon the Property of the Borrower (except
as contemplated by this Agreement and the other Loan Documents) by reason of the
terms of (a) any material mortgage, lease, agreement, or instrument to which the
Borrower is a party or which is binding upon it, (b) any judgment, law, statute,
rule or governmental regulation applicable to the Borrower, or (c) the
Certificate or Articles of Incorporation or By-Laws of the Borrower.

                ------------------------------------------                    
this Agreement and the other Loan Documents create legal and valid Liens on all
the Collateral in the Lender's favor and when all proper filings, recordings,
and other actions necessary to perfect such Liens have been made or taken such
Liens will constitute perfected and continuing Liens on all the Collateral,
having priority over all other Liens on the Collateral, except for Permitted
Liens, securing all the Obligations and enforceable against the Borrower and all
third parties.

          8.3   Organization and Qualification.  Each Borrower is duly

its business and to own its Property.

existing in good standing under the laws of its state of incorporation set forth
on Exhibit F and (b) qualified to do business as a foreign corporation and in
   ---------
good standing in the states set forth opposite its name on Exhibit F, which are

sheet and related statements of income, retained earnings, statements of cash
flows, and changes in stockholders' equity for LSB, as of December 31, 1996 and
for the Fiscal Year then ended, accompanied by the report thereon of LSB's
independent certified public accountants.  LSB has also delivered to the Lender

                                                         -----------           
the Borrower's best estimate of the Borrower's future financial performance for
the periods set forth therein.  The Latest Forecasts have been or will be
prepared on the basis of certain assumptions, which the Borrower believes are
fair and reasonable in light of current and reasonably foreseeable business
conditions; provided, however, that although such forecasts represent the
Borrower's best estimate, the Borrower makes no representation that it will

          10.9 Conditions Precedent to Each Loan. The obligation of the Lender
               ---------------------------------
to make each Revolving Loan or to provide for the issuance of any Letter of

date of any such extension of credit, the following statements shall be true,
and the acceptance by the Borrower of any extension of credit shall be deemed to
be a statement to the effect set forth in clauses (i) and (ii), with the same
effect as the delivery to the Lender of a certificate signed by the chief
executive officer and chief financial officer of the Borrower, dated the date of
such extension of credit, stating that:

               (i)  The representations and warranties contained in this
     Agreement and the other Loan Documents are correct in all material respects
     on and as of the date of such extension of credit as though made on and as
     of such date, except to the extent the Lender has been notified by the

     reason therefor and the Lender has explicitly accepted in writing such
     disclosure in the exercise of its reasonable discretion; and

               (ii) No Event has occurred and is continuing, or would result

               ----------------- 
("Event of Default") if any one or more of the following shall occur for any
  ----------------
reason:

                                       49

          (a)  any failure by Borrower to make payment of principal, interest,
fees or premium on any of the Obligations when due;

          (b)  any representation or warranty made by any Borrower or CCI in
this Agreement, or in any of the other Loan Documents, or, in any Financial

the Lender shall prove to be untrue in any material respect as of the date when
made or furnished;

          (c)  default by Borrower or CCI shall occur in the observance or
performance of any of the covenants and agreements contained in this Agreement,
or in any of the other Loan Documents, or if any such agreement or document
shall terminate (other than in accordance with its terms or the terms hereof or
with the written consent of the Lender) or become void or unenforceable without
the written consent of the Lender other than as a direct result of any conduct
solely on the part of the Lender;

          (d)  any default by Borrower or CCI under any material agreement or
instrument (other than an agreement or instrument evidencing the lending of
money), which default would have a material adverse effect on CCI and the CCI
Borrower Subsidiaries, taken as a whole, and such default continues for thirty
(30) days after such breach first occurs; provided, however, that such grace
period shall not apply, and an Event of Default shall exist, promptly upon such
breach, if such breach may not, in Lender's reasonable determination, be cured
by Borrower during such thirty (30) day grace period;

          (e)  any default by any Borrower in any payment of principal of or
interest on any indebtedness (other than the Obligations) for borrowed money
where the then outstanding amount exceeds $500,000 beyond any period of grace
provided with respect thereto or in the performance of any other agreement, term
or condition contained in any agreement under which any such obligation is
created if (i) the effect of such default is to cause or permit the holder or
holders of such obligation to cause, such obligation to become due prior to its
stated maturity, and (ii) the effect of such default would have a material
adverse effect on the Borrower.

          (f)  any Borrower or CCI shall make a general assignment for benefit
of creditors; or any proceeding shall be instituted by any Borrower seeking to
adjudicate it a bankrupt or insolvent, or seeking liquidation, winding up,
reorganization, arrangement, adjustment, protection, relief, or composition of
it or its debts under any law relating to bankruptcy, insolvency or
reorganization or relief of debtors or seeking entry of an order for relief or
the appointment of a receiver, trustee or other similar official for it or for
any substantial part of its property or any Borrower shall take any corporate
action to authorize any of the actions set forth above in this Subsection
                                                               ----------
11.1(f).
- ------- 

          (g)  an involuntary petition shall be filed or an action or proceeding
otherwise commenced against any Borrower or CCI seeking reorganization,
arrangement or readjustment of such Borrower's debts or for any other relief
under the Federal Bankruptcy Code, as amended, or under any other bankruptcy or
insolvency act or law, state or federal, now or hereafter existing and remain
undismissed or unvacated for a period of sixty (60) days;

other than by an action undertaken by Lender;

discharge the same within thirty (30) days from the date of notice of entry
thereof or to appeal therefrom or reach a negotiated settlement in connection
therewith;

          (l)  any loss, theft, damage or destruction of any item or items of

the CCI Consolidated Group take as a whole; or (ii) is material in amount and is
not adequately covered by insurance;

          (m)  CCI ceases to control each Borrower (the term control having the
meaning given to it in the definition of Affiliate herein);

          (n)  any event or condition shall occur, or exist with respect to a
Plan that would, in the Lender's reasonable judgment, subject the Borrower to
any tax, penalty or other liabilities under the terms of the Plan, under ERISA
or under the Code which in the aggregate are material in relation to the
business, operations, Property or financial or other condition of the CCI
Consolidated Group taken as a whole;

          (o)  there occurs after the date hereof an Ownership Change (as

          11.2 Remedies.
               -------- 

                                       51
<PAGE>
 
          (a)  If an Event of Default exists, the Lender may, without notice to
or demand on the Borrower, do one or more of the following at any time or times
and in any order: (i) reduce the amount of or refuse to make Revolving Loans and
restrict or refuse to arrange for Letters of Credit; (ii) terminate this
Agreement; (iii) declare any or all Obligations to be immediately due and
payable (provided however that upon the occurrence of any Event of Default
described in Sections 11.1(f), 11.1(g), or 11.1(h), all Obligations shall
             -------------------------------------
automatically become immediately due and payable); and (iv) pursue its other
rights and remedies under the Loan Documents and applicable law. The foregoing
shall not be construed to limit the Lender's discretion to take the actions
described in clause (i) of this subparagraph (a) at any other time.

          (b)  If an Event of Default exists: (i) the Lender shall have, in
addition to all other rights, the rights and remedies of a secured party under
the UCC; (ii) the Lender may, at any time, take possession of the Collateral and
keep it on the Borrower's premises, at no cost to the Lender, or remove any part
of it to such other place or places as the Lender may desire, or, the Borrower
shall, upon the Lender's demand, at the Borrower's cost, assemble the Collateral
and make it available to the Lender at a place reasonably convenient to the
Lender; and (iii) the Lender may sell and deliver any Collateral at public or
private sales, for cash, upon credit or otherwise, at such prices and upon such
terms as the Lender deems advisable, in its sole discretion, and may, if the
Lender deems it reasonable, postpone or adjourn any sale of the Collateral by an
announcement at the time and place of sale or of such postponed or adjourned
sale without giving a new notice of sale. Without in any way requiring notice to
be given in the following manner, the Borrower agrees that any notice by the
Lender of sale, disposition or other intended action hereunder or in connection
herewith, whether required by the UCC or otherwise, shall constitute reasonable
notice to the Borrower if such notice is mailed by registered or certified mail,
return receipt requested, postage prepaid, or is delivered personally against
receipt, at least five (5) days prior to such action to the Borrower's address
specified in or pursuant to Section 13.10. If any Collateral is sold on terms
                            ------------- 
other than payment in full at the time of sale, no credit shall be given against
the Obligations until the Lender receives payment, and if the buyer defaults in
payment, the Lender may resell the Collateral without further notice to the
Borrower. In the event the Lender seeks to take possession of all or any portion
of the Collateral by judicial process, the Borrower irrevocably waives: (a) the
posting of any bond, surety or security with respect thereto which might
otherwise be required; (b) any demand for possession prior to the commencement
of any suit or action to recover the Collateral; and (c) any requirement that
the Lender retain possession and not dispose of any Collateral until after trial
or final judgment. The Borrower agrees that the Lender has no obligation to
preserve rights to the Collateral or marshal any Collateral for the benefit of
any Person. Following the occurrence of an Event of Default that is continuing,
the Lender is hereby granted a license or other right to use, without charge,
the Borrower's labels, patents, copyrights, name, trade secrets, trade names,
trademarks, and advertising matter or any similar property, in completing
production of, advertising or selling any Collateral, and the Borrower's rights
under all licenses and all franchise agreements shall inure to the Lender's
benefit, as long as such does not violate in any manner such other loan
agreements that may be in place at such time. The proceeds of sale shall be
applied first to all expenses of sale, including attorneys' fees, and second, in
whatever order the Lender elects, to all Obligations. The Lender will return any
excess to the Borrower and the Borrower shall remain liable for any deficiency.

                                       52
<PAGE>
 
          (c)  If an Event of Default occurs and is continuing, the Borrower
hereby waives: (i) all rights to notice and hearing prior to the exercise by the
Lender of the Lender's rights to repossess the Collateral without judicial
process or to replevy, attach or levy upon the Collateral without notice or
hearing, and (ii) all rights of set-off and counterclaim against Lender.

          (d)  If the Lender terminates this Agreement upon an Event of Default
that has not been cured or otherwise waived to Lender's satisfaction, the
Borrower shall pay the Lender, immediately upon termination, an early
termination penalty equal to the early termination fee that would have been
payable under Article 12 if this Agreement had been terminated on that date
              ----------                                                   
pursuant to the Borrower's election.

     12.  TERM AND TERMINATION.  The term of this Agreement shall extend until
          --------------------                                                
December 31, 2000 (the "Termination Date"). This Agreement shall automatically
be renewed thereafter for successive terms of thirteen (13) months each, unless
this Agreement is terminated as provided below. The Lender and the Borrower
shall each have the right to terminate this Agreement, without premium or
penalty, at the end of the initial term or at the end of any renewal term by
giving the other written notice not less than sixty (60) days prior to the end
of such term by registered or certified mail. The Borrower may also terminate
this Agreement at any time during its initial term or any renewal periods if:
(a) it gives the Lender sixty (60) days prior written notice of termination by
registered or certified mail; (b) it pays and performs all Obligations on or
prior to the effective date of termination; and (c) except as otherwise provided
herein, it pays the Lender, on or prior to the effective date of termination,
one percent (1%) of the average daily balance of the Revolving Loans and Letters
of Credit outstanding under this Agreement for the preceding one hundred eighty
day (180) day period (or from the Closing Date up to and including the date of
termination if less than one hundred eighty (180) days from the Closing Date) if
such termination is made on or prior to the Termination Date. The Lender may
also terminate this Agreement without notice upon an Event of Default that has
not been cured or otherwise waived to Lender's satisfaction. Upon the effective
date of termination of this Agreement for any reason whatsoever, all Obligations
shall become immediately due and payable. Notwithstanding the termination of
this Agreement, until all Obligations are paid and performed in full, the Lender
shall retain all its rights and remedies hereunder (including, without
limitation, in all then existing and after-arising Collateral).

     13.  MISCELLANEOUS.
          ------------- 

          13.1 Cumulative Remedies; No Prior Recourse to Collateral. The
               ---------------------------------------------------- 
enumeration herein of the Lender's rights and remedies is not intended to be
exclusive, and such rights and remedies are in addition to and not by way of
limitation of any other rights or remedies that the Lender may have under the
UCC or other applicable law. The Lender shall have the right, in its sole
discretion, to determine which rights and remedies are to be exercised and in
which order. The exercise of one right or remedy shall not preclude the exercise
of any others, all of which shall be cumulative. The Lender may, without
limitation, proceed directly against the Borrower to collect the Obligations
without any prior recourse to the Collateral.

          13.2 No Implied Waivers. No act, failure or delay by the Lender shall
               ------------------
constitute a waiver of any of its rights and remedies. No single or partial
waiver by the Lender of any provision of this Agreement, or any other Loan
Document, or of breach or default hereunder or thereunder, or 

                                       53
<PAGE>
 
of any right or remedy which the Lender may have, shall operate as a waiver of
any other provision, breach, default, right or remedy or of the same provision,
breach, default, right or remedy on a future occasion. No waiver by the Lender
shall affect its rights to require strict performance of this Agreement.

          13.3   Severability.  If any provision of this Agreement shall be
                 ------------                                              
prohibited or invalid, under applicable law, it shall be effective only to such
extent, without invalidating the remainder of this Agreement.

          13.4   Governing Law. THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN MADE
                 -------------
IN THE STATE OF OKLAHOMA AND SHALL BE GOVERNED BY AND INTERPRETED IN ACCORDANCE
WITH THE LAWS OF SUCH STATE EXCEPT THAT NO DOCTRINE OF CHOICE OF LAW SHALL BE
USED TO APPLY THE LAWS OF ANY OTHER STATE OR JURISDICTION.

          13.5   Consent to Jurisdiction and Venue; Service of Process.
                 ----------------------------------------------------- 

          The Borrower agrees that, in addition to any other courts that may
have jurisdiction under applicable laws, any action or proceeding to enforce or
arising out of this Agreement or any of the other Loan Documents may be
commenced in the appropriate court of the State of Oklahoma for Oklahoma County,
or in the United States District Court for the Western District of Oklahoma, and
each Borrower consents and submits in advance to such jurisdiction and agrees
that venue will be proper in such courts on any such matter. Borrower hereby
waives personal service of process and agrees that a summons and complaint
commencing an action or proceeding in any such court shall be properly served
and shall confer personal jurisdiction if served by registered or certified mail
to the Borrower. Should the Borrower fail to appear or answer any summons,
complaint, process or papers so served within thirty (30) days after the mailing
or other service thereof, it shall be deemed in default and an order or judgment
may be entered against it as demanded or prayed for in such summons, complaint,
process or papers. The choice of forum set forth in this section shall not be
deemed to preclude the enforcement of any judgment obtained in such forum, or
the taking of any action under this Agreement to enforce the same, in any
appropriate jurisdiction.

          13.6   Survival of Representations and Warranties.  All of the
                 ------------------------------------------             
Borrower's representations and warranties contained in this Agreement shall
survive the execution, delivery, and acceptance thereof by the parties,
notwithstanding any investigation by the Lender or its agents, but after the
Closing Date it is recognized that such representations and warranties may be
amended from time to time during the term of this Agreement by written agreement
between the Borrower to the Lender due to changes in circumstances.

          13.7   Indemnification. EACH BORROWER HEREBY INDEMNIFIES, DEFENDS AND
                 ---------------
HOLDS LENDER, AND ITS DIRECTORS, OFFICERS, AGENTS, EMPLOYEES AND COUNSEL,
HARMLESS FROM AND AGAINST ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES,
DEFICIENCIES, JUDGMENTS, PENALTIES OR EXPENSES IMPOSED ON, INCURRED BY OR
ASSERTED AGAINST ANY OF THEM, WHETHER DIRECT, INDIRECT OR CONSEQUENTIAL ARISING
OUT OF OR BY REASON OF ANY LITIGATION, INVESTIGATIONS, CLAIMS, OR

                                       54
<PAGE>
 
PROCEEDINGS (WHETHER BASED ON ANY FEDERAL, STATE OR LOCAL LAWS OR OTHER STATUTES
OR REGULATIONS, INCLUDING, WITHOUT LIMITATION, SECURITIES, ENVIRONMENTAL, OR
COMMERCIAL LAWS AND REGULATIONS, UNDER COMMON LAW OR AT EQUITABLE CAUSE, OR ON
CONTRACT OR OTHERWISE) COMMENCED OR THREATENED, WHICH ARISE OUT OF OR ARE IN ANY
WAY BASED UPON THE NEGOTIATION, PREPARATION, EXECUTION, DELIVERY, ENFORCEMENT,
PERFORMANCE OR ADMINISTRATION OF THIS AGREEMENT, ANY OTHER LOAN DOCUMENT, OR ANY
UNDERTAKING OR PROCEEDING RELATED TO ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY
OR ANY ACT, OMISSION TO ACT, EVENT OR TRANSACTION RELATED OR ATTENDANT THERETO,
INCLUDING, WITHOUT LIMITATION, AMOUNTS PAID IN SETTLEMENT, COURT COSTS, AND THE
FEES AND EXPENSES OF COUNSEL REASONABLY INCURRED IN CONNECTION WITH ANY SUCH
LITIGATION, INVESTIGATION, CLAIM OR PROCEEDING, EXCEPT THAT THIS INDEMNIFICATION
SHALL NOT APPLY TO ANY LOSSES, CLAIMS, DAMAGES, LIABILITIES, JUDGMENTS,
PENALTIES OR EXPENSES IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE LENDER,
AND ITS DIRECTORS, OFFICERS, AGENTS, EMPLOYEES, OR COUNSEL IF SUCH IS DUE TO AND
ARISES FROM OR IN CONNECTION WITH THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF
ANY OF THEM OR THE INTENTIONAL AND WRONGFUL BREACH OF THIS AGREEMENT BY LENDER.
Without limiting the foregoing, if, by reason of any suit or proceeding of any
kind, nature, or description against Borrower, or by Borrower or any other party
against Lender, which in Lender's sole discretion makes it advisable for Lender
to seek counsel for protection and preservation of its liens and security
assets, or to defend its own interest, such reasonable expenses and counsel fees
shall be allowed to Lender. To the extent that the undertaking to indemnify, pay
and hold harmless set forth in this Section 13.7 may be unenforceable because it
                                    ------------    
is violative of any law or public policy, Borrower shall contribute the maximum
portion which it is permitted to pay and satisfy under applicable law, to the
payment and satisfaction of all indemnified matters incurred by Lender. The
foregoing indemnity shall survive the payment of the Obligations and the
termination of this Agreement. All of the foregoing costs and expenses shall be
part of the Obligations and secured by the Collateral.

          13.8 Other Security and Guaranties. The Lender may, without, notice or
               ----------------------------- 
demand and without affecting the Borrower's obligations hereunder, from time to
time: (a) take from any Person and hold collateral (other than the Collateral)
for the payment of all or any part of the Obligations and exchange, enforce or
release such collateral or any part thereof; and (b) accept and hold any
endorsement or guaranty of payment of all or any part of the Obligations and
release any such endorser or guarantor, or any Person who has given any Lien in
any other collateral as security for the repayment of all or any part of the
Obligations, or any other Person in any way obligated to pay all or any part of
the Obligations.

          13.9 Fees and Expenses. The Borrower shall pay to the Lender on demand
               -----------------
all costs and expenses that the Lender pays or incurs in connection with the
negotiation, preparation, consummation, administration, enforcement, and
termination of this Agreement and the other Loan Documents, including, without
limitation: (a) attorneys' and paralegals' fees and disbursements of counsel to
the Lender including, without limitation, a reasonable estimate of the allocable
cost of in-

                                       55
<PAGE>
 
house counsel; (b) costs and expenses (including attorneys' and paralegals' fees
and disbursements including, without limitation, a reasonable estimate of the
allocable cost of in-house counsel) for any amendment, supplement, waiver,
consent, or subsequent closing in connection with the Loan Documents and the
transactions contemplated thereby; (c) costs and expenses of lien and title
searches and title insurance; (d) fees and other charges for recording and
filing financing statements and continuations, and other actions to perfect,
protect, and continue the Security Interest; (e) sums paid or incurred to pay

that the Borrower was obligated to pay or take under the Loan Documents but
failed to pay or take; (f) the expenses of $500 per Lender's auditor per audit
day plus actual costs of appraisals, inspections, and verifications of the
Collateral, including, without limitation, travel, lodging, and meals, for
inspections of the Collateral and the Borrower's operations by the Lender's
agents up to three times per year and whenever an Event of Default exists; (g)
costs and expenses of forwarding loan proceeds, collecting checks and other
items of payment, and establishing and maintaining Payment Accounts and lock
boxes; (h) all amounts that the Borrower is required to pay under the Letter of
Credit Agreement; (i) costs and expenses of preserving and protecting the
Collateral; and (j) costs and expenses (including attorneys' and paralegals'
fees and disbursements and including, without limitation, a reasonable estimate
of the allocable cost of in-house counsel) paid or incurred to obtain payment of
the Obligations, enforce the Security Interest, sell or otherwise realize upon
the Collateral, and otherwise enforce the provisions of the Loan Documents, or
to defend any claims made or threatened against the Lender arising out of the
transactions contemplated hereby (including without limitation, preparations for
and consultations concerning any such matters). The foregoing shall not be
construed to limit any other provisions of the Loan Documents regarding costs
and expenses to be paid by the Borrower. All of the foregoing costs and expenses
shall be charged to the Borrower's loan account as Revolving Loans.

and the same agreement.

                 --------                                                   
convenience only, are without substantive meaning and should not be construed to
modify, enlarge, or restrict any provision.

          13.16  Right of Set-Off. Whenever an Event of Default exists the
                 ----------------
Lender is hereby authorized at any time and from time to time, to set-off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held by Lender or any affiliate of the Lender and other
indebtedness at any time owing by the Lender or any affiliate of the Lender to
or for the credit or the account of the Borrower against any and all of the
Obligations, whether or not then due and payable. Lender agrees promptly to
notify Borrower after any such set-off and application made by Lender, provided
that the failure to give such notice shall not affect the validity of such set-
off and application.

          13.17  Participating Lender's Security Interests. If a Participating
                 -----------------------------------------
Lender shall at any time with the Borrower's knowledge participate with the
Lender in the Loans, the Borrower hereby grants to such Participating Lender,
and the Lender and such Participating Lender shall have and are hereby given, a
continuing lien on and security interest in any money, securities and other
property of the Borrower in the custody or possession of the Participating
Lender, including, the right of set-off, to the extent of the Participating
Lender's participation in the Obligations, and such Participating Lender shall
be deemed to have the, same right of set-off, to the extent of the Participating
Lender's participation in the Obligations under this Agreement, as it would have
if it were a direct lender.

          13.18  WAIVER OF JURY TRIAL. LENDER AND EACH BORROWER ACKNOWLEDGE AND
                 --------------------
AGREE THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT OR THE

ISSUES, AND THEREFORE, THE PARTIES AGREE THAT ANY LAWSUIT GROWING OUT OF ANY
SUCH CONTROVERSY WILL BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE
SITTING WITHOUT JURY. TRIAL BY A JUDGE SITTING WITHOUT A JURY WILL FURTHER
RESULT IN THE AVOIDANCE OF DELAYS, A STREAMLINING OF THE PROCEEDINGS INVOLVED
AND, AS A RESULT, WILL MINIMIZE THE EXPENSE OF ANY SUCH LAWSUIT FOR THE BENEFIT
OF BORROWER AND LENDER. BORROWER HEREBY WAIVES TRIAL BY JURY, RIGHTS OF SET-OFF,
AND THE RIGHT TO IMPOSE COUNTERCLAIMS (EXCEPT FOR COMPULSORY COUNTERCLAIMS) IN
ANY LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH, OR ARISING OUT
OF THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, THE OBLIGATIONS OR THE COLLATERAL,

CLAIM OR DISPUTE HOWSOEVER ARISING, BETWEEN THE BORROWER, AND THE LENDER.
BORROWER HEREBY CONFIRMS THAT THE FOREGOING WAIVERS ARE INFORMED AND FREELY
MADE.

          13.19  AMENDMENT AND RESTATEMENT. THIS AGREEMENT AMENDS, EXTENDS AND
                 -------------------------  
RESTATES IN ITS ENTIRETY THE ORIGINAL LOAN AGREEMENTS. THE EXECUTION OF THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS EXECUTED IN CONNECTION HEREWITH DOES NOT
EXTINGUISH THE INDEBTEDNESS OUTSTANDING IN CONNECTION THEREWITH NOR DOES IT
CONSTITUTE A NOVATION WITH RESPECT TO THE INDEBTEDNESS OUTSTANDING IN CONNECTION
WITH THE ORIGINAL LOAN AGREEMENTS. EACH BORROWER REPRESENTS AND WARRANTS THAT AS
OF THE CLOSING DATE THERE ARE NO CLAIMS OR OFFSETS AGAINST OR DEFENSES OR
COUNTERCLAIMS TO ITS OBLIGATIONS UNDER THE ORIGINAL LOAN AGREEMENTS OR ANY OTHER
LOAN DOCUMENTS. EACH BORROWER WAIVES ANY AND ALL SUCH CLAIMS, OFFSETS, DEFENSES
OR COUNTERCLAIMS, WHETHER KNOWN OR UNKNOWN, ARISING PRIOR TO THE CLOSING DATE.

          13.20  CROSS-COLLATERALIZATION AND CROSS-GUARANTIES. EACH BORROWER
                 --------------------------------------------
UNDER THIS AGREEMENT HEREBY IRREVOCABLY, ABSOLUTELY, AND UNCONDITIONALLY
GUARANTEES THE FULL AND PROMPT PAYMENT TO LENDER WHEN DUE, WHETHER BY
ACCELERATION OR OTHERWISE, OF ANY AND ALL OBLIGATIONS OF EACH OTHER BORROWER
UNDER THIS AGREEMENT, WHETHER SUCH OBLIGATIONS EXIST NOW OR ARE HEREAFTER

OBLIGATIONS OR LIABILITIES OF THE CCI BORROWER SUBSIDIARIES OR ANY MEMBER
THEREOF UNDER THIS AGREEMENT OR UNDER ANY OTHER DOCUMENT OR INSTRUMENT EXECUTED

          ------------------- 

     (a)  Guarantor and any debtor-in-possession or trustee in bankruptcy which
succeeds to the interest of Guarantor hereby unconditionally guarantees the full
and prompt payment to Secured Party when due and after any applicable grace
periods, whether by acceleration or otherwise, of any and all Indebtedness (as
hereinafter defined) of Debtor to Secured Party.
<PAGE>
 
     (b)  As used in this Guaranty, "Indebtedness" shall mean any and all
indebtedness of Debtor to Secured Party under the Loan Agreement, and all
extensions, renewals and replacements thereof, including, without limitation,
all unpaid accrued interest thereon and all costs and expenses payable as
therein provided: (i) whether now existing or hereafter incurred; (ii) whether
direct, indirect, primary, absolute, secondary, contingent, secured, unsecured,
matured or unmatured; (iii) whether such indebtedness is from time to time
reduced and thereafter increased, or entirely extinguished and thereafter
reincurred; and (iv) whether or not such indebtedness is evidenced by a
negotiable or nonnegotiable instrument or any other writing; and (v) whether
such indebtedness is contracted by Debtor alone or jointly or severally with
another or others. Notwithstanding that Debtor may not be obligated to Secured
Party for interest and/or attorneys' fees and expenses on, or in connection
with, the Indebtedness from and after the Petition Date (as hereinafter defined)
as a result of the provisions of the federal bankruptcy law or otherwise,
Indebtedness for which Guarantor shall be obligated under this Guaranty shall
include interest accruing on the Indebtedness at the highest rate provided for
in the Loan Agreement from and after the date on which Debtor files for
protection under the federal bankruptcy laws or from and after the date on which
an involuntary proceeding is filed against Debtor under the federal bankruptcy
laws (herein collectively referred to as the "Petition Date") and all reasonable
attorneys' fees and expenses incurred by the Secured Party from and after the
Petition Date in connection with the Indebtedness.

     (c)  Guarantor acknowledges that valuable consideration supports this
Guaranty, including, without limitation, any commitment to lend, extension of
credit or other financial accommodation, whether heretofore or hereafter made by
Secured Party to Debtor; any extension, renewal or replacement of any
Indebtedness; any forbearance with respect to any Indebtedness or otherwise; any
cancellation of an existing guaranty; or any other valuable consideration.

     3.   Secured Party's Costs and Expense. Guarantor agrees to pay on demand
          ---------------------------------                                   
all costs and expenses of every kind incurred by Secured Party: (a) in enforcing
this Guaranty; (b) in collecting any Indebtedness from Debtor or Guarantor after
the occurrence of an Event of Default that is continuing; (c) in realizing upon
or protecting any collateral for this Guaranty or for payment of any
Indebtedness; and (d) for any other purpose related to the Indebtedness or this
Guaranty. "Costs and expenses" as used in the preceding sentence shall include,
without limitation, reasonable attorneys' fees incurred by Secured Party in
retaining counsel for advice, suit, appeal, any insolvency or other proceedings
under the Federal Bankruptcy Code or otherwise, or for any purpose specified in
the preceding sentence.

     4.   Nature of Guaranty: Continuing, Absolute and Unconditional.
          ---------------------------------------------------------- 

     (a)  This Guaranty is and is intended to be a continuing guaranty of
payment of the Indebtedness (irrespective of the aggregate amount thereof)
independent of and in addition to any other guaranty, endorsement, collateral or
other agreement held by Secured Party therefor or with respect thereto, whether
or not furnished by Guarantor.

     (b)  This Guaranty is absolute and unconditional and shall not be changed
or affected by any representation, oral agreement, act or thing whatsoever,
except as herein provided. This Guaranty is intended by Guarantor to be the
final, complete and exclusive expression of the agreement between Guarantor and
Secured Party relating to this Guaranty. No modification or amendment of any
provision of this Guaranty shall be effective unless in writing and signed by a
duly authorized officer of Secured Party, and then shall be effective in the
specific instance and for the specific purpose given.

     5.   Certain Rights and Obligations.
          ------------------------------ 

     (a)  Guarantor authorizes Secured Party, without notice, demand or any
reservation of rights against Guarantor and without affecting Guarantor's
obligations hereunder, from time to time: (i) to renew, extend, increase,
accelerate (pursuant to the terms of the Loan Agreement) or otherwise change the
time for payment of, the terms of, or the interest on, the Indebtedness or any
part thereof; (ii) to accept from any person or entity and hold collateral for
the payment of the Indebtedness or any part thereof, and to exchange, enforce or
refrain from enforcing, or release, such collateral or any part thereof; (iii)
to accept and hold any indorsement or guaranty of payment of the Indebtedness or
any part thereof, and to discharge, release or substitute any such obligation of
any such indorser or guarantor, or any person or entity who has given any
security interest in any collateral as security for the payment of the
Indebtedness or any part thereof, or any other person or entity in any way
obligated to pay the Indebtedness or any part thereof, and to enforce or refrain
from enforcing, or compromise or modify, the terms of any obligation of any such
indorser, guarantor, person or entity; (iv) to dispose of any and all collateral
securing the Indebtedness in any manner as Secured Party, in its sole
discretion, may deem appropriate, and to direct the order or manner of such
disposition and the enforcement of any and all endorsements and guaranties
relating to the Indebtedness or any part thereof as Secured Party, in its sole
discretion, may determine; and (v) to determine the manner, amount and time of
application of payments and credits, if any, to be made on all or any part of
any component or components of the Indebtedness (whether principal, interest,
costs and expenses, or otherwise).

                                       3
<PAGE>
 
     (b)  If any default shall be made in the payment of any Indebtedness after
such is due and after expiration of applicable grace periods, Guarantor hereby
agrees to pay the same in full: (i) without deduction by reason of any setoff,
defense or counterclaim of Debtor; (ii) without requiring protest or notice of
nonpayment or notice of default to Guarantor, to Debtor or to any other person;
(iii) without demand for payment or proof of such demand; (iv) without requiring
Secured Party to resort first to Debtor (this being a guaranty of payment and
not of collection) or to any other guaranty or any collateral which the Secured
Party may hold; (v) without requiring notice of acceptance hereof or assent
hereto by Secured Party; and (vi) without requiring notice that any Indebtedness
has been incurred or of the reliance by the Secured Party upon this Guaranty;
all of which Guarantor hereby waives.

     (c)  Guarantor's obligation hereunder shall not be affected by any of the
following, all of which Guarantor hereby waives: (i) any failure to perfect or
continue the perfection of any security interest in or other lien on any
collateral securing payment of any Indebtedness or Guarantor's obligations
hereunder; (ii) the invalidity, unenforceability, propriety or manner of
enforcement of, or loss or change in priority of, any such security interest or
other lien; (iii) any failure to protect, preserve or insure any such
collateral; (iv) failure of Guarantor to receive notice of any intended
disposition of such collateral; (v) any defense arising by reason of the
cessation from any cause whatsoever of liability of the Debtor including,
without limitation, any failure, negligence or omission by Secured Party in
enforcing its claims against the Debtor or any person liable for all or any part
of the Indebtedness; (vi) any release, settlement or compromise of any
obligation of Debtor; (vii) the invalidity or unenforceability of any of the
Indebtedness, or (viii) it is especially and expressly agreed that if the
indebtedness of said Debtor now or at any time hereafter exceeds the amount
permitted by law, or if any Debtor's obligation to pay interest, attorneys'
fees, costs or expenses or any other sums ceases to exist by operation of law,
or if said Debtor is not liable because the act of creating the obligation is
ultra vires, or the officers creating same acted without authority, and for
- ----- -----                                                                
these reasons the indebtedness to Secured Party which Guarantor agrees to pay
cannot be enforced against the Debtor, such fact shall in no manner affect
Guarantor's liability hereunder, notwithstanding the fact that said Debtor is
not liable for such indebtedness, but Guarantor shall be liable hereunder to the
same extent as Guarantor would have been if the indebtedness of the said Debtor
had been fully enforceable against said Debtor.

     6.   Other Parties; Joint and Several Liability.
          ------------------------------------------ 

     (a)  If more than one party executes this Guaranty, or if other separately
executed guaranties of the Indebtedness presently, or in the future, exist,
Secured Party shall have the right to discharge or release one or more of the
undersigned from any 

                                       4
<PAGE>
 
obligation hereunder, in whole or in part, without in any way releasing,
impairing or affecting its right against the other or others of the undersigned.
The failure of any other person to sign this Guaranty shall not release or
affect the obligations or liability of any of the undersigned.

     (b)  If more than one party executes this Guaranty, the obligations of the
undersigned hereunder shall be joint and several, and the term "Guarantor" shall
include each as well as all of them.

     7.   Guaranty of Performance. Guarantor also guarantees the full, prompt
          -----------------------                                            
and unconditional performance of all obligations and agreements of every kind
owed or hereafter to be owed by Debtor to Secured Party under the Loan
Agreement.

     8.   RESERVED.
          -------- 

     9.   Termination. This Guaranty shall remain in full force and effect as to
          -----------                                                           
the Guarantor until Secured Party shall actually receive from such Guarantor
written notice of its discontinuance, or notice of the death or judicial
declaration of incompetency of such Guarantor; provided, however, this Guaranty
shall remain in full force and effect thereafter until all Indebtedness
outstanding or contracted or committed for (whether or not outstanding) before
the receipt of such notice by Secured Party, and any extensions, renewals or
replacements thereof (whether made before or after receipt of such notice),
together with interest accruing thereon after such notice, shall be finally and
irrevocably paid in full. Discontinuance of this Guaranty as to one Guarantor
shall not operate as a discontinuance hereof as to any other Guarantor. Payment
of all of the Indebtedness from time to time shall not operate as a
discontinuance of this Guaranty, unless notice of discontinuance as above
provided has theretofore actually been received by Secured Party. If after
receipt of any payment of all or any part of the Indebtedness, Secured Party is
for any reason compelled to surrender such payment to any person or entity,
because such payment is determined to be void or voidable as a preference,
impermissible setoff, or a diversion of trust funds, or for any reason, this
Guaranty shall continue in full force notwithstanding any contrary action which
may have been taken by Secured Party in reliance upon such payment, and any such
contrary action so taken shall be without prejudice to Secured Party's rights
under this Guaranty and shall be deemed to have been conditioned upon such
payment having become final and irrevocable.

     10.  Representations and Warranties. Guarantor represents and warrants to
          ------------------------------                                      
Secured Party as follows:

     (a)  Guarantor has the corporate power and authority to execute, deliver
and perform its obligations under this Guaranty, and this Guaranty constitutes
the legal, valid and binding

                                       5
<PAGE>
 
obligation of Guarantor, enforceable against Guarantor in accordance with its
terms, except as limited by bankruptcy, insolvency, fraudulent conveyance or
other laws of general application relating to the enforcement of creditor's
rights.

     (b)  The execution, delivery, and performance by Guarantor of this Guaranty
will not conflict with, result in a breach of, or constitute a default under, or
result in the imposition of any lien upon any assets of Guarantor pursuant to
the provisions of, any material indenture, mortgage, deed of trust, security
agreement, franchise, permit, license, or other instrument or agreement to which
Guarantor or its properties is bound.

     (c)  No authorization, approval, or consent of, and no filing or
registration with, any court, governmental authority, or third party is
necessary for the execution, delivery or performance by Guarantor of this
Guaranty or the validity or enforceability thereof, except as may be required
under the Uniform Commercial Code and applicable state law to perfect Lender's
rights in and to the Collateral.

     (d)  Guarantor and Debtor are members of an affiliated and integrated group
of corporations and are engaged in related businesses and supporting lines of
business; Guarantor has received and will receive a direct and indirect material
benefit from the transactions evidenced by and contemplated in the Loan
Agreement and the other Loan Documents; this Guaranty is given by Guarantor in
furtherance of the direct and indirect business interests and corporate purposes
of Guarantor, and is necessary to the conduct, promotion and attainment of the
businesses of Debtor and Guarantor; and the value of the consideration received
and to be received by Guarantor is reasonably worth at least as much as the
liability and obligation of Guarantor hereunder;

     (e)  Guarantor is familiar with, and has independently received books and
records regarding, the financial condition of Debtor and is familiar with the
value of any and all collateral (if any) intended to secure the Indebtedness;
however, Guarantor is not relying on such financial condition or any such
collateral (if any) as an inducement to enter into this Guaranty;

     (f)  Guarantor has not been induced to enter into this Guaranty on the
basis of a contemplation, belief, understanding or agreement that any Person
other than Guarantor will be liable to pay the Indebtedness; and

     (g)  Neither Lender nor any other Person has made any representation,
warranty or statement to, or promise, covenant or agreement with, Guarantor in
order to induce Guarantor to execute this Guaranty.

     11.  Covenants. Guarantor covenants and agrees that, as long as the
          ---------                                                     
Indebtedness or any part thereof is outstanding or Secured Party has any
commitment to Debtor:

     (a)  Guarantor will furnish promptly to Secured Party written notice of the
occurrence of any default under this Guaranty;

     (b)  Guarantor will furnish promptly to Secured Party such additional
information concerning Guarantor as Secured Party may request;

     (c)  Guarantor will obtain at any time and from time to time all
authorizations, licenses, consents or approvals as shall now or hereafter be
necessary or desirable under all applicable laws or regulations or otherwise in
connection with the execution, delivery and performance of this Guaranty and
will promptly furnish copies thereof to Secured Party; and

     (d)  Guarantor will not use any of the Revolving Loans to make any
Distributions or Restricted Investments to any of its Affiliates or Subsidiaries
except as allowed under Section 9.14 of the Loan Agreement.

     12.  Right of Setoff. During the existence of an Event of Default the
          ---------------                                                 
Guarantor grants to Lender a right of setoff upon any and all monies, securities
or other property of Guarantor, and the proceeds therefrom, now or hereafter
held or received by or in transit to Lender from or for the account of
Guarantor, whether for safekeeping, custody, pledge, transmission, collection or
otherwise, and also upon any and all deposits (general or special) and credits
of Guarantor, and any and all claims of Guarantor against Lender at any time
existing. The right of setoff granted pursuant to this Paragraph shall be
cumulative of and in addition to Lender's common law right of setoff.

     13.  Miscellaneous.
          ------------- 

     (a)  "Debtor" and "Guarantor" as used in this Guaranty shall include: (i)
in the case of a partnership Debtor or Guarantor, any new partnership which
shall have been created by reason of the admission of any new partner or
partners therein or by reason of the dissolution of the existing partnership by
voluntary agreement or the death, resignation or other withdrawal of any
partner; and (ii) in the case of a corporate Debtor, any other corporation into
or with which Debtor shall have been merged, consolidated, reorganized or
absorbed.

     (b)  Without limiting any other right of Secured Party, whenever Secured
Party has the right to declare any Indebtedness to be immediately due and
payable (whether or not it has so declared) under the terms of the Loan
Agreement, Secured Party at its sole election may set off against the
Indebtedness any and all monies 

                                       7
<PAGE>
 
then owed to Guarantor by Secured Party in any capacity, and Secured Party shall
be deemed to have exercised such right of setoff immediately at the time of such
election even though any charge therefor is made or entered on Secured Party's
records subsequent thereto.

     (c)  Guarantor's obligation hereunder is to pay the Indebtedness in full
when due after expiration of the applicable grace periods according to its
terms, and shall not be affected by any extension of time for payment by the
Debtor resulting from any proceeding under the Federal Bankruptcy Code or any
similar law.

     (d)  No course of dealing between Debtor or Guarantor and Secured Party and
no act, delay or omission by Secured Party in exercising any right or remedy
hereunder or with respect to the Indebtedness shall operate as a waiver thereof
or of any other right or remedy, and no single or partial exercise thereof shall
preclude any other or further exercise thereof or the exercise of any other
right or remedy. Secured Party may remedy any default by Debtor under any
agreement with Debtor or with respect to the Indebtedness in any reasonable
manner without waiving the default remedied and without waiving any other prior
or subsequent default by Debtor. All rights and remedies of Secured Party
hereunder are cumulative.

     (e)  Secured Party and Guarantor as used herein shall include the
successors or assigns of those parties. The rights and benefits of Secured Party
hereunder shall, if Secured Party so directs, inure to any party acquiring any
interest in the Indebtedness or any part thereof. If any right of Secured Party
hereunder is construed to be a power of attorney, such power of attorney shall
not be affected by the subsequent disability or incompetence of Guarantor.

     (f)  Captions of the paragraphs of this Guaranty are solely for the
convenience of Secured Party and Guarantor, and are not an aid in the
interpretation of this Guaranty.

     (g)  GUARANTOR AGREES THAT ANY ACTION OR PROCEEDING TO ENFORCE OR ARISING
OUT OF THIS GUARANTY MAY BE COMMENCED IN THE DISTRICT COURT LOCATED IN OKLAHOMA
COUNTY, OKLAHOMA, OR IN THE DISTRICT COURT OF THE UNITED STATES LOCATED IN THE
WESTERN DISTRICT OF OKLAHOMA, IN WHICH SECURED PARTY HAS AN OFFICE, AND
GUARANTOR WAIVES PERSONAL SERVICE OF PROCESS AND AGREES THAT A SUMMONS AND

SERVED AND SHALL CONFER PERSONAL JURISDICTION IF SERVED BY REGISTERED MAIL TO
GUARANTOR, OR AS OTHERWISE PROVIDED BY THE LAWS OF THE STATE OF OKLAHOMA OR THE
UNITED STATES.

     (h)  If any provision of this Guaranty is unenforceable in whole or in part
for any reason, the remaining provisions shall continue to be effective.
Furthermore, in lieu of such illegal, 

                                       8
<PAGE>
 
invalid or unenforceable provision there shall be added automatically as a part
of this Guaranty a provision as similar in terms to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable.
No provision herein or in any other Loan Document evidencing the Indebtedness
shall require the payment or permit the collection of interest in excess of the
maximum permitted by applicable law.

rights to the collateral against prior parties or to marshal any collateral for
the benefit of Guarantor or any other third party.

THE TRANSACTION DOCUMENTS OR THE TRANSACTIONS RELATED THERETO. GUARANTOR
REPRESENTS AND WARRANTS THAT NO REPRESENTATIVE OR AGENT OF SECURED PARTY HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SECURED PARTY WILL NOT, IN THE EVENT
OF LITIGATION, SEEK TO ENFORCE THIS RIGHT TO JURY TRIAL WAIVER. GUARANTOR

          indebtedness payable by ClimaChem or the ClimaChem Subsidiaries will

          and the ClimaChem Subsidiaries' insurance needs and (b) assist
          ClimaChem in obtaining appropriate insurance. ClimaChem and the

          provide assistance in the preparation of, and recordkeeping for,

          Subsidiaries in any of their international activities as may be agreed
          to by LSB and ClimaChem from time to time.

2.   Space Allocation.  ClimaChem acknowledges that LSB must devote a
     ----------------                                                
significant portion of its office facilities (the "LSB Premises"), including its
principal offices and financial accounting offices, to the performance of this
Agreement. ClimaChem agrees that the market lease value of the Premises and 

                                     - 3 -
<PAGE>
 
the costs of acquiring, maintaining, and improving the LSB Premises will be
allocated between LSB and ClimaChem based on the proportionate usage of the LSB
Premises by LSB and ClimaChem. LSB will have the sole discretion and authority
to determine the proportionate usage of the LSB Premises by LSB and ClimaChem.
The value of ClimaChem's proportionate share of the LSB Premises and costs
incurred by LSB in connection with the LSB Premises will constitute a cost
incurred by LSB in performing the Services for purposes of paragraph 4 of this
Agreement.

3.   Employee Benefits.  From and after the date of this Agreement, LSB will

permit the employees of ClimaChem and the ClimaChem Subsidiaries (the "ClimaChem
Employees") to continue to participate in the employee benefit plans, including
stock option plans, sponsored by LSB (collectively, the "LSB Plans")  on the
same basis as such employees participated immediately prior to the date of this
Agreement.  Notwithstanding the foregoing, nothing contained in this Agreement
will prohibit LSB from modifying or terminating the LSB Plans so long as (a)
such modification or termination will apply to all participants in the LSB Plans
or (b) with respect to any modification or termination that does not apply to
all participants in the LSB Plans, ClimaChem consents to such modification or
termination, which consent will not be unreasonably withheld.  The contributions
of the ClimaChem Employees to any LSB Plan and the costs associated with
participation by ClimaChem Employees in the LSB Plans will be accounted for
separately from contributions of, and costs associate with, participation by
persons who are not ClimaChem Employees.  The costs associated with
participation by the ClimaChem Employees in the LSB Plans will constitute costs
incurred by LSB in performing the Services for purposes of paragraph 4 of this
Agreement.

4.   Payment for Services.  ClimaChem shall pay to LSB an amount equal to all
     --------------------                                                    
direct and indirect costs and expenses, including third party charges, incurred
by LSB in performing the Services under this Agreement until the date that this
Agreement is terminated pursuant to paragraph 5 of this Agreement.  LSB's costs
and expenses shall include, without limitation, (a) the value of all time
expended, directly or indirectly, on behalf of ClimaChem or the ClimaChem
Subsidiaries by LSB employees, other than the President or Chief Financial
Officer of LSB (who services are to be compensated under that certain Management
Agreement, dated the November 21, 1997, between the parties hereto), including
salaries, wages and fringe benefits paid by LSB; (b) all amounts paid by LSB on
behalf of ClimaChem and the ClimaChem Subsidiaries to the employees of ClimaChem
and the ClimaChem Subsidiaries; (c) the cost of supplies and materials, and the
value of equipment, utilized by LSB for, and on behalf of, ClimaChem and the
ClimaChem Subsidiaries; (d) all payables and obligations incurred by, or

                                     - 4 -

by other parties and entities in connection with assisting LSB to perform the
Services; (f) reasonable travel, lodging, and meal expenses in connection with
LSB performing the Services; (g) all costs incurred pursuant to paragraphs 2 and
3 of this Agreement; and (h) all other reasonable costs and expenses incurred by
LSB in connection with performing the Services. LSB will invoice ClimaChem each
month during the term of this Agreement for the cost and expenses incurred
during the prior month. Each invoice will be due and payable by ClimaChem to LSB
on or before the 15/th/ day of the month following the date of such invoice.
Upon ClimaChem's request, ClimaChem will have the right to review the
documentation supporting LSB's invoices to ClimaChem.

will continue for a period of ten years, unless sooner terminated pursuant to
the terms of this paragraph 5. Notwithstanding the foregoing, LSB may terminate
this Agreement on 30 days' written notice to ClimaChem if ClimaChem defaults
under any of the terms or provisions of this Agreement or if LSB sells 50% or
more of the issued and outstanding stock of ClimaChem or sells, transfers or
disposes of all, or substantially all, of the assets of ClimaChem.

     6.2  Certain Limitations.  Each party acknowledges that the Services will
          -------------------                                                 
          be provided only with respect to the businesses of ClimaChem and the
          ClimaChem Subsidiaries as such businesses exist as of the date of this
          Agreement or as otherwise mutually agreed by the parties. LSB will not
          be obligated to provide Services for the benefit of entities other
          than ClimaChem and the ClimaChem Subsidiaries.

     6.3  Certain Information.  ClimaChem will, and will cause the ClimaChem

          Subsidiaries to, provide any information needed by LSB to perform the
          Services pursuant to this Agreement. If the failure to provide such
          information renders the performance of any requested Service
          impossible or unreasonably difficult, LSB may, upon reasonable notice
          to ClimaChem, refuse to provide such Service.

ClimaChem, retain any affiliate of LSB to perform all or any part of the
Services.  LSB may retain non-affiliates of LSB to perform the Services unless
ClimaChem objects in writing to LSB. Notwithstanding the foregoing, LSB may
retain, without notice to ClimaChem and without ClimaChem having the right to
object, such other parties or entities that are not affiliates of LSB to perform
the Services in the event of exigent circumstances.  The determination of an
"exigent circumstance" will be in the sole and absolute discretion of LSB.  The
fees and charges of each individual or entity retained by LSB pursuant to this

for purposes of paragraph 4 of this Agreement.

                             TAX SHARING AGREEMENT
                             ---------------------


     THIS TAX SHARING AGREEMENT ("Agreement") is entered into this 21st day of
November, 1997, between LSB INDUSTRIES, INC., a Delaware corporation ("LSB"),
and CLIMACHEM, INC., an Oklahoma corporation ("ClimaChem").

                             W I T N E S S E T H:
                             ------------------- 

     WHEREAS, LSB owns 100% of the issued and outstanding shares of capital
stock of ClimaChem, and ClimaChem owns, directly or through intermediaries, 100%
of the issued and outstanding shares of capital stock of the entities listed on
Schedule 1 attached hereto (the "ClimaChem Subsidiaries");

     WHEREAS, LSB, ClimaChem, and the ClimaChem Subsidiaries are members of the
affiliated group of corporations of which LSB is the common parent
(collectively, the "LSB Consolidated Group") within the meaning of (S) 1504(a)
of the Internal Revenue Code of 1986, as amended (the "Code");

     WHEREAS, ClimaChem and the ClimaChem Subsidiaries (collectively, the
"ClimaChem Group") would be members of an affiliated group of corporations of
which ClimaChem would be the common parent within the meaning of (S) 1504(a) of
the Code if ClimaChem were not a subsidiary of LSB; and

     WHEREAS, it is the intent and desire of the parties hereto that a method be
established for determining the rights and obligations among the LSB
Consolidated Group, the ClimaChem Group, and the members of the LSB Consolidated
Group which are not members of the ClimaChem Group (the "LSB Group") as to tax
liabilities, refunds and related administrative matters.

     NOW, THEREFORE, in consideration of the mutual covenants and promises
contained herein, the parties hereto agree as follows:

1.   Filing of Tax Returns.  The tax returns of LSB and the ClimaChem Group will
     ---------------------                                                      
be filed as follows:

     1.1  Consolidated Federal Returns.  LSB will have exclusive authority to
          ----------------------------                                       
          file consolidated federal income tax returns pursuant to (S) 1502 of
          the Code on behalf of the LSB Consolidated Group which includes, but
          is not limited to, the ClimaChem Group ("Consolidated Federal
          Returns").

     1.2  Composite Returns.  LSB, or a member of the LSB Group designated by
          -----------------                                                  
          LSB, will have exclusive authority to file each state, local or
          foreign income tax return or other tax return required to be filed by
          any member of the ClimaChem Group which computes taxes payable to a
          taxing jurisdiction in respect of the income, operations or assets of
          two or more corporations (including at least 
<PAGE>
 
          one member of the ClimaChem Group and one member of the LSB Group)
          based on combined or consolidated reporting or apportionment of
          business income under the unitary business concept ("Composite
          Return").

     1.3  All Other Returns.  Except as otherwise provided in paragraphs 11 and
          -----------------                                                    
          12 of this Agreement, LSB, or a member of the LSB Group designated by
          LSB, will have exclusive authority to file all income tax or franchise
          tax returns with respect to the income, operations or assets of the
          LSB Consolidated Group or any member thereof, including, but not
          limited to, the ClimaChem Group and any member of such group.

     1.4  Tax Information.  To facilitate the preparation and filing of
          ---------------                                              
          Consolidated Federal Returns, Corporate Returns and other returns,
          ClimaChem will, on a timely basis, provide LSB with all information
          reasonably required by LSB with respect to the income, operations and
          assets of each member of the ClimaChem Group.

2.   Tax Controversies.
     ----------------- 

     2.1  Tax Returns.  LSB or its designee will have exclusive authority to
          -----------                                                       
          represent each member of the LSB Consolidated Group, including, but
          not limited to, members of the ClimaChem Group, before any
          governmental agency or any court regarding tax matters related to any
          Consolidated Federal Return, Composite Return or any other tax return
          including, but not limited to, (a) the exclusive control of any
          response to any examination by any taxing authority, and (b) the
          exclusive control over any contest of any issue therein through a
          Final Determination (as defined below), including, but not limited to,
          whether, and in what form, to conduct such contest and whether, and on
          what basis, to settle such contest. For purposes of this paragraph 2,
          the term "Final Determination" means with respect to any issue or item
          for any period, (a) in the context of federal income taxes, (i) a
          final, nonappealable decision by a court of competent jurisdiction,
          (ii) the expiration of the time for assessment of taxes or filing a
          claim for refund or, if a refund claim has been timely filed, the
          expiration of the time for instituting suit in respect of such refund
          claim, if no further adjustment to the items of income, gain,
          deduction, loss, or credit for such period may thereafter be made,
          (iii) the execution of a closing agreement under (S) 7121 of the Code,
          (iv) the acceptance by the IRS or its counsel of a tender pursuant to
          an

                                      -2-
<PAGE>
 
          offer in compromise pursuant to (S) 7122 of the Code, (v) the
          execution of a Form 870A, or (vi) any other final and irrevocable
          determination of taxes for any period, and (b) in the context of other
          taxes, any comparable, final, nonappealable, and irrevocable
          determination of taxes for such period.

     2.2  Notification of Controversy.  LSB or its designee will timely notify
          ---------------------------                                         
          ClimaChem of any correspondence and tax controversies with any taxing
          authority relating to items of any member of the ClimaChem Group and
          will promptly provide ClimaChem with copies of all such correspondence
          upon the request of ClimaChem. Subject to LSB's exclusive authority as
          provided herein, ClimaChem will have the right exercisable on a timely
          basis to consult with LSB with respect to the handling of any such
          correspondence or controversies. LSB or its designee will permit
          ClimaChem or its representative to attend any hearing or other
          proceedings relating to such controversies to the extent that the
          subject of such hearings or proceeding relates to a member of the
          ClimaChem Group.

3.   Tax Sharing.
     ----------- 

     3.1  ClimaChem Payment Obligation.  ClimaChem shall pay to LSB the dollar
          ----------------------------                                        
          value of any federal, state or local income tax liability (including,
          without limitation, deficiencies, interest and penalties) relating to
          the ClimaChem Group and its respective businesses and operations with
          respect to any taxes of the ClimaChem Group for any taxable year or
          period ending on or prior to December 31, 2007. Such tax liability of
          the ClimaChem Group will be calculated as if the ClimaChem Group was a
          separate consolidated tax group and not part of the LSB Consolidated
          Group (the resulting amount is referred to as the "ClimaChem Stand-
          Alone Tax Liability").

     3.2  Payments by ClimaChem of ClimaChem Stand-Alone Tax Liability.  The
          ------------------------------------------------------------      
          ClimaChem Stand-Alone Tax Liability will be paid to LSB pursuant to
          this paragraph 3.2. On or before each March 31, June 30, September 30,
          and December 31 of each year, LSB will make a good faith estimate of
          the ClimaChem Stand-Alone Tax Liability for the current tax quarter
          (the amount of each such estimate is the "Tax Estimate"), and will
          promptly provide ClimaChem with a summary of the calculation of the
          Tax Estimate (the "Tax Notice"). Notwithstanding any objection by
          ClimaChem to

                                      -3-
<PAGE>
 
          the calculation of the Tax Estimate, within 15 days after the date of
          the Tax Notice, ClimaChem will pay to LSB the Tax Estimate for the
          period set forth in the Tax Notice (the "Quarterly Payment"). LSB will
          adjust the amount of the Tax Estimate as may be necessary from time to
          time during the tax year, and ClimaChem agrees that the one or more
          Quarterly Payments will be increased or decreased, as appropriate, to
          account for the adjustments, if any, in the amount of the Tax
          Estimate. If the sum of all Quarterly Payments during a tax year is
          less than the ClimaChem Stand-Alone Tax Liability for such year, as
          determined by LSB, then ClimaChem will, within 15 days after receipt
          of notice by LSB, pay to LSB, the amount equal to the deficiency. If
          the amount of all Quarterly Payments during a tax year is greater than
          the ClimaChem Stand-Alone Tax Liability for such year, as determined
          by LSB, then LSB will, within 15 days of the determination of the
          ClimaChem Stand-Alone Tax Liability, pay to ClimaChem the amount of
          such excess.

     3.3  Objection to Calculations.  The calculations made by LSB for each tax
          -------------------------                                            
          year pursuant to this paragraph 3 will be conclusive as to ClimaChem,
          unless written objection is received by LSB within 30 days after the
          end of such tax year. If written objection is timely made by
          ClimaChem, and the parties are unable to agree upon the correct
          calculations, the disputed issue will be submitted to Ernst & Young,
          L.P. or other accounting firm of recognized national standing selected
          by LSB in its reasonable discretion, whose determination will be
          final. All costs and expenses relating to the accounting firm's
          determination will be paid by ClimaChem. In the event the parties
          agree to a different determination or the accounting firm's review
          results in a different calculation, appropriate payments will be made
          in the amount of payment.

     3.4  Earnings and Profits Allocation.  The parties understand that the
          -------------------------------                                  
          method of allocation of federal income tax liabilities used for the
          determination of earnings and profits for federal income tax purposes
          under governing law may differ from the methods prescribed herein for
          sharing of economic burdens of such taxes. To the extent permitted by
          governing law and not otherwise inconsistent with the best interests
          of LSB, LSB agrees to make an election or take any other action
          permitted under governing law which would cause such method of
          allocation to resemble as closely as practical the method of sharing
          the economic burdens of such tax hereunder.

4.   Administrative Matters.
     ---------------------- 

     4.1  General.  The provisions of this Agreement will be administered by
          -------                                                           
          LSB. Except as otherwise expressly governed by the terms of this
          Agreement, LSB or its designee may use any reasonable method in making
          any computations or allocations hereunder.

     4.2  Power of Attorney.  In order to carry out the purposes and intent of
          -----------------                                                   
          this Agreement, ClimaChem hereby grants, and agrees that it will cause
          each member of the ClimaChem Group to grant, to LSB and to appropriate
          officers of LSB a power of attorney to undertake in the name of the
          appropriate member of the ClimaChem Group any action contemplated
          herein, including, without limitation, the filing of returns and
          claims for refund, making of elections, handling of controversies, and
          receipt of funds. To the extent that such power of attorney is not
          recognized or respected, ClimaChem agrees to take, and to cause each
          member of the ClimaChem Group to take, such further actions, including
          grants to LSB of additional powers of attorney or execution of returns
          or other documents as may be reasonably requested by LSB to carry out
          the provisions of this Agreement.

     4.3  Payments.  Amounts owed by either party hereto in respect of tax
          --------                                                        
          refunds or credits received by such party to which the other party is
          entitled hereunder will be paid by the party receiving the refund to
          the other party within five days after the receipt or credit of such
          refund, and amounts owed by either party hereto in respect of tax
          increases will be paid by such party to the other party within 30 days
          after the Final Determination with respect thereto. If not timely
          paid, any amounts payable hereunder will bear interest from the date
          due at one percent in excess of the Prime Rate as published in The
          Wall Street Journal from time to time.

     4.4  Records.  LSB and ClimaChem agree that all records, including, but not
          -------                                                               
          limited to, returns, supporting schedules, workpapers, correspondence
          and other documents within the possession of either, and relating to
          the tax liabilities or refunds of either, will be retained by each for
          as long as they may be material to the determination of such
          liabilities or refunds and will be made reasonably available to either
          party upon request.

     4.5  Return Preparation and Defense.
          ------------------------------ 

          4.5.1  In General. Each party hereto agrees that it will cooperate
                 ----------
                 with the other, and its representatives, in a prompt and timely
                 manner, in connection with (a) the preparation and filing of,
                 and (b) any administrative or judicial proceeding involving,
                 any Consolidated Federal Return, Composite Return or other tax
                 return filed, or required to be filed, by LSB, ClimaChem or
                 members of their respective Groups. Such cooperation will
                 include, but not be limited to, the making available to the
                 other party, during normal business hours, of all books,
                 records (including, but not limited to, workpapers and
                 schedules), information, officers, and employees (without
                 substantial interruption of employment) reasonably requested
                 and necessary or useful in connection with any tax filing,
                 inquiry, audit, investigation, dispute, litigation, or other
                 matter.

          4.5.2  Consistency.  In filing any Consolidated Federal Return or
                 -----------                                               
                 Composite Return, LSB will make all computations of taxable
                 amounts and tax on a basis consistent with the computations of
                 such amounts in prior tax returns for the respective taxing
                 jurisdictions except to the extent otherwise required by the
                 laws, rules, or regulations of the respective taxing
                 jurisdictions or other applicable authority or as a result of a
                 change in factual circumstances. In determining how to treat
                 any matter for which there is no precedent in prior returns or
                 controlling legal authority, LSB will, in good faith, take into
                 account the reasonable interests of ClimaChem after due
                 consultation with ClimaChem.

5.   Miscellaneous.
     ------------- 

     5.1  Term.  This Agreement is effective as to the taxable years (or
          ----                                                          
          portions thereof) commencing after December 31, 1996, and will
          continue for a period of ten years or at such time as ClimaChem is no
          longer included in LSB's consolidated federal tax return or state
          consolidated,

                                      -6-
<PAGE>
 
          combined or unitary tax returns, if earlier, unless sooner terminated
          pursuant to the terms of this paragraph 5. Notwithstanding the
          foregoing, LSB may terminate this Agreement on 60 days' written notice
          to ClimaChem if ClimaChem defaults under any of the terms or
          provisions of this Agreement or if LSB sells all, or substantially
          all, of the issued and outstanding stock of ClimaChem. Unless
          otherwise agreed in writing by the parties, this Agreement will remain
          in force and be binding so long as the statutory period for
          assessments or refunds under applicable law remains unexpired for any
          taxable period as to which either party may have a claim against the
          other under this Agreement.

     5.2  Expenses.  ClimaChem will reimburse or pay to LSB ClimaChem's
          --------                                                     
          allocable share of all expenses (including professional fees) incurred
          by LSB or its designee in connection with the preparation or audit of
          Consolidated Federal Returns, Composite Returns, or other returns or
          contests or controversies related to such returns. The allocation of
          such expenses between LSB and ClimaChem will be made to LSB in its
          sole discretion.

     5.3  Successors and Assigns.  This Agreement will bind and inure to the
          ----------------------                                            
          benefit of the respective successors and assigns of the parties
          hereof, but no assignment will relieve any party of its obligations
          hereunder without the written consent of the other parties.

     5.4  Notices.  All notices and other communications hereunder will be in
          -------                                                            
          writing and will be delivered by hand or mailed by registered or

                 FIRST AMENDMENT TO LOAN AND SECURITY AGREEMENT
                 ----------------------------------------------


     This First Amendment to Loan and Security Agreement ("First Amendment") is
made as of  June 1 , 1995 by and between THE CIT GROUP/EQUIPMENT FINANCING, INC.
("Lender") and DSN CORPORATION ("Borrower").

     WHEREAS, Lender and Borrower entered into a Loan and Security Agreement
dated as of October 31, 1994 ("Loan Agreement") pursuant to which Lender made
certain loans to Borrower upon the terms and conditions set forth in the Loan
Agreement and the related Loan Documents;

     WHEREAS, Lender has agreed to increase the amount of the loans under the
Loan Agreement; and

     WHEREAS, Lender and Borrower have agreed to certain other modifications and
amendments to the Loan Agreement as set forth in this First Amendment.

     NOW, THEREFORE, in consideration of the terms and conditions herein, and of
any loans or other credit facilities heretofore, now or hereafter made to or for
the benefit of Borrower by Lender, the parties hereto agree to the following
amendments. and modifications to the Loan Agreement:

     1.   Definitions.  The term "Note" shall be amended to mean that certain
          -----------                                                        
Amended and Restated Promissory Note which evidences the Loan, substantially in
the form attached hereto as Exhibit "A".

     2.   The Loan.  Section 2.1 of the Loan Agreement shall be amended to
          --------                                                        
increase the amount Lender is willing to lend to a sum not to exceed the
principal amount of sixteen million, five hundred thousand dollars ($16,500,000)
(the "Loan"), the proceeds of which are to be disbursed by Lender exclusively
for the payment of the costs and expenses incurred in connection with the
construction and testing of the DSN Plant and the costs and expenses incurred in
connection with the preparation, negotiation, recordation, title insurance and
filing requirements pursuant to the Loan Documents.

     3.   Disbursement Methods.  Pursuant to Section 2.2 of the Loan Agreement,
          --------------------                                                 
Lender has disbursed the initial $12,750,000 of the Loan proceeds. Pursuant to
the terms hereof, Lender has agreed to advance an additional $3,750,000 in two
disbursements. Concurrent with the execution of this First Amendment, Lender
will make the first disbursement of $1,875,000. The second (and final)
disbursement of the remaining $1,875,000 will be made upon Borrower's successful
completion and demonstration of the DSN Plant reliability test (the "Test")
defined herein as: (1) Strong Nitrate Acid ("SNA") product quality meeting grade
specifications pursuant to the offtake Agreement dated  January 1, 1994 with
Monsanto Company ("product specifications"); (2) SNA product throughput 
<PAGE>
 
meeting the product specifications; and (3) reliability demonstrated by the DSN
Plant operating for the earlier of, a period of thirty (30) consecutive calendar
days at the rate of 275 tons per day of SNA meeting the product specifications,
or 8,250 tons of SNA meeting the product specifications. The Test may be
interrupted for any reason ("Incident") and receive full credit for production
prior to the Incident provided that the 275 tons per day volume indicated above
at product specification is produced in 30 consecutive days.

     Upon completion of the Test, Borrower shall issue a "Final Completion
Certificate" to Lender and Lender's consultant, Brown and Root, Inc. Upon
receipt of the Final Completion Certificate, Brown & Root, Inc. shall issue to
Lender an "Independent Consultant Completion Certificate" in form and substance
satisfactory to Lender confirming completion of the Test. Failure of Borrower to
complete such Test and Brown & Root, Inc. issuing its acceptable "Independent
Consultant Completion Certificate" to Lender by July 31, 1995 shall, unless
otherwise agreed by Lender, terminate any requirement of Lender to make such
second disbursement.

     Except as may otherwise be expressly modified by this First Amendment, the
remaining terms and conditions of Section 2.2 of the Loan Agreement remain in
effect.

     4.   Repayment of the Loan.  Section 2.3 of the Loan Agreement shall be
          ---------------------                                             
amended to reflect the modifications in the repayment provisions of the Note as
follows:

     (a)  Lender has advanced the full above-referenced $12,750,000 of Loan
          proceeds to Borrower. Concurrent with the execution of this First
          Amendment, Lender shall advance the first additional disbursement of
          $1,875,000, resulting in a then aggregate principal advance of
          $14,625,000. Principal and precomputed interest thereon shall be
          payable in 84 equal consecutive monthly installments. For purposes of
          amortization and payment of the principal and precomputed interest
          under the Note, the Term Out Period shall be deemed to commence June 
          1, 1995 with the first installment payment in the amount of
          $234,279.80 being due on July 1, 1995 and thereafter payable in 
          eighty-three (83) equal consecutive monthly payments. Provided,
          however, that at such time as the second disbursement of $1,875,000 is
          made by Lender, the second disbursement will be added to the then
          outstanding principal balance of the Note and the then remaining
          installments during the remaining Term Out Period shall be
          recalculated to provide for equal consecutive monthly installments of
          the then aggregate unpaid principal balance and precomputed interest
          thereon for the remainder of the Term Out Period.

                                       2

          Loan Documents shall be due and payable in full on the last day of the
          Term Out Period (June 1, 2002) unless due and payable earlier as
          provided in the Loan Documents.

     (c)  In the event the DSN Plant shall not be fully operational, and the
          requirements for the DSN Plant Completion Date shall not have been
          completed by October 15, 1995, the principal balance outstanding under
          the Note and all accrued and unpaid interest and charges not sooner
          paid when due under the Note, and all other Obligations of Borrower
          owing under any and all of the Loan Documents shall at the option of
          Lender, be fully due and payable on October 15, 1995.

          insurance, in form, amount with such priority and endorsements as
          Lender may reasonably require.

disbursed by Lender exclusively for the payment in full of the approved costs
and expenses incurred in connection with the construction and the purchase of
the Equipment.

      Section 2.2   Disbursement.
                    ------------ 

      (a) The proceeds of each Loan disbursed under this Agreement shall be

Lender. Borrower shall also deliver to Lender prior to each funding, such
invoices, statements, vouchers and other sale documents and proof of ownership
by Borrower in connection with each Unit as may be acceptable to Lender.
Notwithstanding a partial funding of the Units by the first funding, Lender's
lien shall be a first priority lien in all of the Units at any time delivered to
Borrower.

      Section 2.3   Repayment of the Loan. Borrower promises to repay the Loan
                    ---------------------                                     
as follows:

      (a) The Loan shall be evidenced by the Notes. Each Note shall be dated
concurrently with each disbursement and shall be payable in eighty-four (84)
consecutive equal monthly installments of principal and interest from the date
thereof at the rate provided in Section 2.4 below, commencing the first day of
the month following each disbursement of the Loan proceeds.

     (b) In the event the second disbursement of the Loan proceeds is not
disbursed by October 15, 1995, any obligation of Lender to make any further Loan

     (c) Borrower's obligation to pay all amounts payable hereunder is absolute
and unconditional and shall not be affected by any circumstance of any character

abatement or reduction or any right which Borrower may have against Under, the
manufacturer or supplier of any of the Equipment or anyone else for any reason
whatsoever; (ii) the invalidity, enforceability or disaffirmance of this

      Section 2.4   Interest Charges. The outstanding principal balance of each
                    ----------------                                           
Note shall bear interest at a rate per annum equal to the Treasury Rate plus two

instance, interest shall be calculated on the basis of a 360-day year consisting
of twelve 30-day months.

      Section 2.5   Late Charge Rate. In the event Borrower fails to pay any
                    ----------------                                        
amount hereunder when due under any Note, the amount on all Notes shall bear
charges thereon calculated at the Late Charge Rate. At any time when any Event
of Default has occurred, irrespective of any cure periods, and continues for
over ten (10) days, Borrower will pay interest on the Loan at the Late Charge
Rate.

      Section 2.6   Maximum Interest. In no event shall the interest charged
                    ----------------                                        
with respect to the Obligations exceed the maximum amount permitted under
applicable law. Notwithstanding anything to the contrary herein or elsewhere, if
at any time the rate of interest called for hereunder or under the Notes or
other Loan Document (the "Stated Rate") exceeds the highest rate of interest
permissible under any applicable law (the "Maximum Lawful Rate"), then for so
long as the Maximum Lawful Rate would be so exceeded, the rate of interest
payable shall be equal to the Maximum Lawful Rate; provided, however, that if at
                                                   -----------------            
any time thereafter the Stated Rate is less than the Maximum Lawful Rate,
Borrower shall, to the extent permitted by law, continue to pay interest at the
Maximum Lawful Rate until such time as the total interest received by Lender is
equal to the total interest which Lender would have received had the Stated Rate
been (but for the operation of this provision) the interest rate payable.
Thereafter, the interest rate payable shall be the Stated Rate unless and until
the Stated Rate again exceeds the Maximum Lawful Rate, in which event this
provision shall again apply.

day of any month, upon at least thirty (30) Business Days' prior written notice
to Lender. Such prepayment of a Note shall be accompanied by the payment of all
principal, all accrued but unpaid interest on such Note to the date of
prepayment and all outstanding and unpaid costs, fees and expenses. In addition,
the prepayment of such Note shall be made with a prepayment fee in an amount
equal to the greater of (a) two percent (2.0%) of the outstanding principal
             -------

principal and interest payments which would have been payable during, the
remainder of the term in the absence of the prepayment, using a discount rate
equal to one percent (1.0%) plus the yield to maturity, as of the Third Business

life of such Note, as such yield to maturity is reported on page 5. ("U.S.

prepayment on the Note which reflects the indebtedness relating to the
disbursement for that particular Unit, within 30 days after the occurrence of
such Event of Loss, in an amount determined (i) by multiplying (a) the unpaid
principal amount of such Note by (b) a fraction the numerator of which shall

                                      10

which shall be the original principal amount of such Note (the amount obtained
by multiplying (i)(a) and (i)(b) hereof shall be herein referred to as the
"Prepaid Principal Amount") (ii) by adding interest accrued, with respect to the
Prepaid Principal Amount, to the date of such prepayment and (iii) by adding an

possession or control. Lender shall be deemed to have satisfied its duty of due
care with respect to Collateral in its custody and control if it accords to such
Collateral treatment substantially equal to the treatment Lender accords its own
property, or if Lender takes such action with respect to the Collateral as
Borrower requests in writing, but no failure to comply with any such request nor
any omission to do any such act requested by Borrower shall be presumptively
deemed, from that failure or omission, an absence of reasonable care. Lender
shall not be responsible or liable for any shortage, discrepancy, damage, loss
or destruction of any part of the Collateral wherever the same may be located
and regardless of the cause thereof, unless caused by Lender's gross negligence
or willful misconduct. Lender does not, by anything contained herein or in any
other Loan Document or otherwise, assume any obligation of Borrower under
Railcar Lease or any other contract or agreement assigned to Lender or in which

continuance of any Event of Default:

          (a)  Lender may declare all the Obligations not otherwise due to be
     forthwith due and payable, (provided that, in the case of the occurrence of
     any Event of Default described in Sections 8.1(j) or (k), all the
                                                ------    ---         
     Obligations shall forthwith become due and payable without such
     declaration) whereupon the unpaid amount of the Obligations (including any
     applicable prepayment fee) shall become immediately due and payable without
     presentment, demand, protest or notice of any kind, all of which are hereby
     expressly waived.

          (b)  Notwithstanding the foregoing in Section 8.2(a) but subject to
     the provisions of Section 9.10, the effect of an event described in Section
     8.1(a) as an occurrence of an Event of Default shall be after Lender gives
     notice of such payment

                                       32
<PAGE>
 
     Default to Borrower and Borrower shall not have paid such amount within
     three (3) days of such Notice. The effect as an Event of Default of any
     other event described in Section 8.1 may be waived by Lender in writing.

          (c)  In addition to all other rights provided herein or at law, Lender
     shall have all of the rights and remedies of a secured party under the UCC
     and all of the rights and remedies granted under each of the Loan
     Documents. At any time when an Event of Default has occurred and is
     continuing, Lender may enter any premises where the Collateral is located,
     take physical possession of the Collateral or any part thereof, and
     maintain such possession on Borrower' premises or remove any or all of the
     Collateral to such other place or places as Lender desires in its sole
     discretion. If Lender exercises its right to take possession of any
     Collateral upon the occurrence and during the continuance of any Event of
     Default, Borrower, upon Lender's demand, will assemble the Collateral and
     at Lender's option, make it available to Lender at Borrower' premises at
     which it is located or deliver it to such place or places as Lender
     directs. Borrower hereby waives to the full extent permitted by law all
     rights to notice and hearing prior to Lender's exercise of its rights to
     take possession of the Collateral without judicial process or to replevy,
     claim and deliver, attach or levy upon the Collateral ex parte. Lender
                                                           -- -----        
     shall not be under any obligation to marshall any assets in favor of
     Borrower or any other party or against or in payment of any or all of the
     Obligations.

          (d)  Lender may sell, lease or otherwise dispose of and deliver any or
     all of the Collateral at public or private sale, for cash, upon credit or
     otherwise, at such prices and upon such terms as Lender, in its sole
     discretion, deems advisable, all in accordance with the applicable
     provisions of the UCC including the standard of commercial reasonableness.

          (e)  The requirement of reasonable notice with respect to a
     disposition of the Collateral shall be met if such notice is mailed both by
     regular and certified mail, postage prepaid to Borrower at the address as
     set forth herein at least ten days before the time of the event of which
     notice is being given. Subject to the provisions of any applicable Loan
     Document or law governing the enforcement of liens or security interests,
     Lender may be the purchaser at any public sale, and to the extent permitted
     by applicable law, at any private sale, free from any right of redemption,
     which Borrower also waives.

          (f)  The Proceeds of any sale of any of the Collateral shall be
     applied first to all costs and expenses of sale, including attorneys' fees,
     and second to the payment (in whatever order Lender elects) of all of the
     Obligations. Lender will return any excess Proceeds to Borrower, subject to

                                       33
<PAGE>
 
     the claims of any other parties with an interest in the Collateral or the
     Proceeds, and Borrower shall remain liable to Under for any deficiency. If
     any Collateral is sold or leased by Lender upon credit or for future
     payment or delivery, Lender shall not be liable for the failure of the
     purchaser to pay for such Collateral, and in such event Lender may resell
     or re-lease the same.

          (g)  Lender may exercise any other right or remedy it may have at law
     or in equity with respect to the Obligations or the subject matter of this
     Agreement. The rights and remedies provided for herein are cumulative and
     not exclusive of any other of such rights and remedies or any other rights
     or remedies provided by law.

binding upon and inure to the benefit of the respective successors and assigns
of the parties hereto; provided, however, that no interest herein may be
assigned by Borrower without the prior written consent of Lender. The rights and
benefits of Lender hereunder shall, if Lender so agrees, inure to any party
acquiring any interest in the Obligations or any part thereof. In the event of
any such assignment by Lender, Borrower agrees that such assignment by Lender
shall be free from any set-off, counterclaim defense or other claim that any
such Borrower may have against such assignee, without waiving any claim such
Borrower may have against Lender. The terms "Lender" and "Borrower" as used
herein shall include the respective successors and assigns of such parties.

agreement between them and supersedes all prior agreements and understandings
regarding the Loan. No modification, rescission, waiver, release or amendment of
any provision of this Agreement shall be made, except by a written agreement
signed by Borrower and a duly authorized officer of Lender.

     Section 9.6    Indemnification.
                    --------------- 

          (a)  If after receipt of any payment of all or any part of the
     Obligations, Lender is for any reason compelled to surrender such payment
     to any person or entity, because such payment is determined to be void or
     voidable as a preference, impermissible setoff, or a diversion of trust
     funds, or for any other reason, Borrower's Obligations under the Notes
     shall continue in full force and Borrower shall indemnify and hold Lender
     harmless for, the amount of such payment surrendered. The provisions of
     this Section shall be and remain effective notwithstanding any contrary
     action which may have been taken by Lender in reliance upon such payment,
     and any such contrary action so taken shall be without prejudice to
     Lender's rights under this Section and shall be deemed to have been
     conditioned upon such payment having become final and irrevocable. The
     provisions of this Section shall survive the termination of this Agreement.

          (b)  Borrower hereby indemnifies and holds Lender, and its directors,
     officers, agents, employees and counsel, harmless from and against any and
     all losses, liabilities, damages, injuries, costs, expenses and claims of
     any and every kind (except claims brought by Borrower against Lender for
     breach of this Agreement of the Loan Documents) including without
     limitation, court costs and attorneys' fees imposed on or incurred by or
     asserted against any of them, whether direct, indirect or consequential
     arising out of or by reason of any litigation, investigations, claims, or
     proceedings whether based on any federal, state or local laws or other
     statutes or regulations commenced or threatened, which arise out of or are
     in any way based upon the negotiation, preparation, execution, delivery,
     enforcement, performance or administration of this Agreement or any other
     Loan Document, or any undertaking or proceeding relating to any of the
     transactions contemplated hereby or by any act, omission to act, event or
     transaction related or attended thereto, except this indemnification shall
     not apply to any losses, liabilities, damages, injuries, costs, expenses
     and claims caused by the gross negligence or willful misconduct of Lender.

          (c)  Borrower hereby indemnifies Lender and agrees to hold Lender
     harmless from and against any and all losses, liabilities, damages,
     injuries, costs, expenses and claims of any and every kind whatsoever
     (including, without limitation,

                                       35
<PAGE>
 
     court costs and attorneys' fees) which at any time or from time to time may
     be paid, incurred or suffered by, or asserted against Lender for, with
     respect to, or as a direct result of the violation by Borrower of the
     Environmental Laws or any laws or regulations relating to Hazardous
     Substance, treatment, storage, disposal, generation and transportation,
     air, water and noise pollution, soil or ground or water contamination, the
     handling, storage or release into the environment of Hazardous Substance,
     or with respect to, or as a direct or indirect result of the presence on or
     under, or the escape, seepage, leakage, spillage, discharge, emission or
     release from, properties utilized by Borrower or EDC in the conduct of
     their respective business into or upon any land, the atmosphere, or any
     watercourse, body of water or wetland, of any Hazardous Substance
     (including, without limitation, any losses, liabilities, damages, injuries,
     costs, expenses or claims asserted or arising under the Environmental
     Laws).

          (d)  Without limiting any of the foregoing, if, by reason of any suit
     or proceeding of any kind, nature or description against Borrower, which,
     in Lender's sole discretion makes it advisable for Lender to seek counsel
     for protection and preservation of its Lens, security or assets or to
     defend its own interest, such reasonable expenses and counsel fees shall be
     allowed to Lender. The foregoing indemnity shall survive the payment of the
     Obligations and the termination of this Agreement. All of the foregoing
     costs and expenses shall be part of the Obligations and secured by the
     Collateral.

     Section 9.7    Stamp or other Tax. Should any stamp, excise, sales, use or

become payable in respect of this Agreement, or any other Loan Document, any

against Lender or any agent or attorney of Lender or a defense to payment of any
Obligations of Borrower under this Agreement or any other Loan Document, for any
reason, including commission of a tort or violation of any contractual duty or
duty implied by law. Borrower agrees, to the fullest extent that it may lawfully

     This First Amendment to Loan & Security Agreement ("First Amendment") is
dated as of November 15, 1995 and is made and entered into by and between DSN
Corporation, an Oklahoma corporation ("Borrower") and The CIT Group/Equipment
Financing, Inc., a New York corporation ("Lender").

                                   RECITALS
                                   --------

     This First Amendment is made with reference to the following facts:

     A.   Borrower and Lender entered into a certain Loan and Security Agreement
dated as of September 25, 1995 ("Loan Agreement") pursuant to which Lender made
available to Borrower a credit facility to finance the acquisition of ten
railcars; from Trinity Industries, Inc. 'Me terms used herein and not otherwise
defined shall have the meaning specified for such terms in the Loan Agreement.

     B.   Pursuant to the terms of the Loan Agreement, disbursements in
connection with the purchase of the railcars were to be made in two fundings. On
September 25, 1995, Lender made the first funding in the amount of $584,900.00
in connection with Borrower's acquisition of the first five railcars.

     C.   Borrower has now taken possession of four of the remaining five
railcars. Borrower is informed that the remaining fifth railcar has been shipped
by Trinity but its whereabouts, at this time, is unknown.

     NOW THEREFORE, in consideration of the terms and conditions herein and of
the Loans heretofore, now or hereafter made to or for the benefit of Borrower by
Lender, the parties hereto agree to the following amendments and modifications
to the Loan Agreement:

     1.   Funding and Acceptance. Borrower represents that it has inspected and
          ----------------------                                               
accepted the four remaining railcars, copies of which invoices are attached
hereto, and pursuant to its Request for Advance and Pay Proceeds Letter, Lender
shall disburse the amount of $467,920.00 pursuant to Section 2.2 of the Loan
Agreement. DSN acknowledges and agrees that CIT is not obligated to fund the sum
required for the final railcar and that at such time as its delivery and
acceptance by DSN, any funding will be in CITs sole discretion.

     2.   Tangible Net Worth Amendment. Section 6.10 of the Loan Agreement shall
          ----------------------------                                          
be amended to read as follows:

          "Section 6.10 Tangible Net Worth". LSB shall maintain at all times, on
           --------------------------------                                     
          a consolidated basis, a minimum tangible net worth of $75,000,000
          after
<PAGE>
 
          subtracting treasury stock and $85,000,000 before subtracting treasury
          stock as at December 31, 1995 and March 31, 1996, $76,000,000 after
          subtracting treasury stock and $86,000,000 before subtracting treasury
          stock as at June 30, 1996, $77,000,000 after subtracting treasury
          stock and $87,000,000 before subtracting treasury stock as at
          September 30, 1996 and $78,000,0000 after subtracting treasury stock
          and $88,000,000 before subtracting treasury stock as at December 31,
          1996. Thereafter, LSB shall maintain a minimum tangible net worth of
          not less than $85,000,000 after subtracting treasury stock. The term
          tangible net worth is defined as total stockholders' equity, after
          deducting any treasury stock, less all assets that are considered
                                        ----  
          intangible assets under GAAP (including but not limited to goodwill,
          patents, trademarks, certain deferred charges (as approved by Lender)
          and customer lists).

          LSB shall also maintain, on a consolidated basis, a leverage position
          (defined as total liabilities divided by tangible net worth, after
          deducting treasury stock) of 2.25:1 as at December 31, 1995 and at all
          times thereafter."

     3.   Conditions Subsequent. Borrower further agrees that within ten (10)
          ---------------------                                              
days of the execution of this letter that it will provide CIT with amendments to
the Railcar Lease Agreement and such amendments to the Consulting Agreement as
may be acceptable to CIT, in its sole discretion.

     4.   Representations and Warranties. Borrower represents and warrants as
          ------------------------------

          -------------                                                 
Agreement, the terms of which are incorporated herein, and the breach of any
representation, warranty or covenant contained herein or the failure to observe
or comply with any term or agreement contained herein, shall constitute a
Default under the Loan Agreement and Lender shall be entitled to exercise all
rights and remedies it may have under the Loan Agreement, the Loan Documents and
at applicable law. Borrower agrees to pay all costs, expenses and attorneys'
fees incurred by Lender in connection with the negotiation and preparation of
this First Amendment and any other documents in connection herewith including
all search, recording and title insurance expenses and in carrying out or
enforcing the terms of this First Amendment. Except as expressly provided
herein, Lender is not waiving any rights under the Loan Agreement or any other
Loan Document and, except as expressly provided herein or as previously modified
in a writing signed by Lender, all of the terms, covenants, and conditions of
the Loan Agreement remain unmodified and in full force and effect. Capitalized

The covenant as calculated based on operations does not consider any cash
dividends to LSB as permitted by the Senior Notes to be issued by ClimaChem.
Under the Senior Notes ClimaChem will be permitted to dividend up to 50% of its
annual net income (absent a default, etc.).  ClimaChem's projected Net Income
for 1998 and 1999 is $7.7 million and $11.8 million, respectively.  The
suggested covenant assumes LSB will receive the full dividend it is entitled to.

                              GUARANTY AGREEMENT


     THIS GUARANTY AGREEMENT ("Guaranty"), dated as of November 21, 1997, is
made by CLIMACHEM, INC., an Oklahoma corporation ("Guarantor"), in favor of CIT
GROUP/EQUIPMENT FINANCING, INC., a New York corporation ("CIT").

     A.   Guarantor hereby requests CIT to enter into an amendment of the loans
owing by DSN Corporation ("Debtor") to CIT and the termination of the existing
guaranty of LSB Industries, Inc.

     B.   It is in the direct interest of, and benefit to, Guarantor, because
of the intercorporate or business relations between Guarantor and Debtor, to
guarantee the payment and performance of all of Debtor's Obligations (as defined
below) to CIT, and Guarantor will derive substantial economic benefits from the
relationship between CIT and Debtor.

     C.   CIT's willingness to make the loan modifications and terminate LSB's
guaranty is conditional upon, among other things, Guarantor's execution and
delivery of this Guaranty to CIT.

     In consideration of the foregoing facts and for other valuable
consideration, Guarantor hereby agrees as follows:

     1.   Guaranty.
          -------- 

          1.1  Guarantor, hereby unconditionally and irrevocably guarantees to
CIT and its successor, transferees and assigns (a) the prompt and complete
payment when due (whether at the stated maturity, by acceleration or otherwise)
of all obligations and indebtedness of Debtor to CIT ("Obligations"), now
existing or hereafter incurred, arising out of or in connection with any loan
agreements, promissory notes or other documents or agreements between Debtor and
CIT, and (b) the due and punctual performance and observance, strictly in
accordance with the terms of any such loan agreements or promissory notes by
Debtor, of each of the material terms, conditions, covenants agreements and
indemnities of Debtor thereunder, and if for any reason whatsoever Debtor shall
fail to do so, Guarantor shall promptly perform and observe the same. Guarantor
further agrees to pay any and all out-of-pocket costs and expenses, including
reasonable attorney's fees, which may be paid or incurred by CIT in collecting
from Debtor or Guarantor any or all of the Obligations and/or in enforcing any
rights hereunder.

          1.2  The obligations of Guarantor under this Guaranty shall be
continuing, absolute and unconditional under any and all circumstances and shall
be paid or performed by Guarantor regardless of (a) the validity, legality or
enforceability of any loan agreement or promissory note by Debtor in favor of
CIT, any of the Obligations or any collateral security or other guaranty
therefor at any time or from time to time held by CIT; (b) any 
<PAGE>
 
defense, offset or counterclaim which may at time be available to, or asserted
by, Debtor or Guarantor against CIT; or (c) any other event or circumstance
which may constitute, or might be construed to constitute, an equitable or legal
discharge or a surety or a guarantor, it being the purpose and intent of
Guarantor that this Guaranty and Guarantor's obligations hereunder shall remain
in full force and effect and be binding upon Guarantor and its successors until
the Obligations and any obligations of Guarantor under this Guaranty shall have
been satisfied by final payment in full.

          1.3  Guarantor hereby consents, without the necessity of any
reservation of rights against Guarantor and without notices to or assent by
Guarantor that (a) any demand for payment of any of the Obligations made by CIT
may be rescinded by CIT and any of the Obligations continued; (b) the
Obligations, or the liability of any party upon or for any part thereof, or any
collateral security documents or guaranty therefor, may, from time to time, in
whole or in part, be renewed, extended, amended, modified, accelerated, settled,
compromised, subordinated, waived, surrendered or released by CIT; (c) any loan
agreement or any promissory note by Debtor in favor of CIT, any collateral,
security documents or other guaranties or documents in connection therewith may
be amended, modified, supplemented or terminated, in whole or in part, as CIT
may deem advisable from time to time; and (d) any collateral securing the
payment of the Obligations may be sold, exchanged, waived, surrendered or
released, Guarantor remaining bound hereunder notwithstanding the occurrence of
any of the foregoing. CIT shall not have any duty to protect, secure, perfect or
insure any collateral securing the payment of the Obligations. This is a
guaranty of payment and performance, and not merely of collection. Guarantor
waives any requirement that CIT make any demand, commence suit or exercise any
other right or remedy under any loan agreement by Debtor in favor of CIT prior
to enforcing its rights against Guarantor hereunder. Guarantor waives diligence,
presentment, protest, demand for payment and/or notice of default or non-payment
to or upon Debtor or Guarantor with respect to the Obligations. Guarantor waives
any right to require CIT to marshall assets in favor of Debtor, Guarantor or any
other person. When making any demand hereunder against Guarantor, CIT may, but
shall be under no obligation to, make a similar demand on any other guarantor,
and any failure by CIT to make any such demand or to collect any payments from
any such other guarantor or any release of such other guarantor shall not
relieve Guarantor of its obligations and liabilities hereunder, and shall not
impair or affect the rights and remedies, express or implied, or as a matter of

                                  COMPANY NOTE
                                  ------------

$2,000,000                                 Oklahoma City, Oklahoma

     FOR VALUE RECEIVED, Climate Master, Inc. (the "Maker"), promises to pay to
the order of the Oklahoma County Finance Authority, an Oklahoma public trust
(the "Authority"), or any subsequent holder or. holders of this Note (the
Authority and any subsequent holder or holders are hereinafter referred to as
the "Holder"), at the offices of the Authority, or at such other place as may be
designated in writing by the Holder, the principal sum of Two Million Dollars
($2,000,000), or so much thereof as shall be disbursed, together with interest
thereon at the rate hereinafter specified, payable as set forth herein.

     As used herein, the following terms shall have the meanings indicated:

     Note Rate shall mean a variable rate of interest per annum equal to the
     ---------                                                              
variable rate of interest per annum, payable by The Oklahoma Industrial Finance
Authority a body corporate and politic, and an instrumentality, agency and
department of the State of Oklahoma, on its $10,000,000 Taxable General
Obligation industrial Finance Bonds, Series P (the "Series P Bonds"), (3%) with
a minimum interest rate of ten percent (10%). From and after the date hereof
until August 1, 1989, interest shall accrue at an initial interest rate of 12.9%
adjustable as herein provided. The Note Rate and the amount of Maker's required
payments hereunder shall be adjusted (upward or downward) on August 1, 1989, and
on the first (1st) day of every third (3rd) month thereafter (referred to herein
after as the "Payment Adjustment Date"); provided, however, that in no event
shall the Note Rate or the interest cost on this Note exceed any statutory
limitation, [currently fourteen percent (14%)]. Prior to any change in the Note
Rate, the Maker and the Authority shall be mailed notice in writing by the
Holder by first class mail at the addresses then on file at the offices of the
Holder at least one (1) day prior to the end of the then effective Note Rate
period, but any failure in respect of such mailing will not affect the validity
of such notice of Note Rate change, nor shall the Holder be liable or
responsible for any such failure of mailing and/or the failure of the Maker or
the Authority to receive such notice, absent gross negligence or fraud. Such
notice shall specify the effective dates of the new Note Rate and the amount of
interest due and payable on the succeeding payment dates during the ensuing
designated period. Further, such Note Rate shall prevail until written notice to
the contrary has been mailed by the Holder to the Maker and the Authority or
until final maturity of this Note.

     Loan Agreement shall mean the Project Loan Agreement dated as of July 1,
     --------------                                                          
1989 by and between the Authority and the Maker relating to the disbursement of
the loan evidenced by this Note. At the option of the Holder, a default under
the Project Loan Agreement shall constitute a default under this Note.
<PAGE>
 
     Commencing on the lst day of September, 1989, and on the 1st day of each
calendar month thereafter, interest shall be paid on the unpaid principal
balance of this Note based upon the amount actually funded.

     Commencing on the 1st day of September, 1989, and continuing on the lst day
of each calendar month thereafter, principal shall be paid in fifty-six (56)
consecutive equal monthly installments.

     The last monthly payment of principal and interest, due on May 1, 1994,
will be in the then remaining balance of principal and interest. Each of the
foregoing payments of interest and principal shall be applied first to the
payment of any unpaid interest hereunder at the Note Rate, and the balance, if
any, shall be applied to the principal sum.

     Subject to the provisions of the Loan Agreement, the right is reserved to
prepay this Note, in whole or in part, provided that the prepayment is made on a
regularly scheduled principal and interest installment payment date. Any full or
partial prepayment shall apply to (i) costs and expenses of the Holder in
effecting the prepayment; (ii) interest to accrue to the repayment date thereof
and not previously paid; (iii) the principal amount of this Note.

     Holder will provide Maker with notice and thirty (30) days' opportunity to
cure any non-monetary default and fifteen (15) days' opportunity to cure any
monetary default. While any default exists hereunder all sums herein promised to
be paid shall bear interest at the rate equal to fourteen percent (14%) per
annum, but not more than the Maximum Rate, (as defined below), provided, that
any default interest so required to be paid when added to all other interest
paid to date under this Note, shall not result in this Company Note bearing an
interest rate in excess of the Maximum Rate. Such default interest shall accrue
from the date of default to the date on which such default is cured to the
satisfaction of the Holder. All past due sums will be paid at the time of and as
a condition precedent to the curing of any default hereunder. During the
existence of any such default, the Holder may apply payments received on any
amount due hereunder or under the terms of any instrument now or hereafter
evidencing or securing any such indebtedness as the Holder may determine.

     Subject to the maximum interest rate permitted to be paid by public trusts
pursuant to Title 60 Oklahoma Statutes 1981, Section 176(e), (the "Maximum
Rate"), the Holder may collect a late charge equal to four cents (.04) on each
dollar of each payment which is not paid within ten (10) days from the due date
thereof, for the, purposes of covering the extra expenses involved in handling
delinquent installments. This late charge provision shall not be applicable in
the event the Holder, at its option, elects to

                                       2
<PAGE>
 
receive interest at the increased rate as previously provided in the event of
default.

     Payment of this Note is secured by a Mortgage with Power of Sale of
Tenant's Interest in Lease (the "Mortgage") a Security Agreement and other
security instruments covering property located in Oklahoma County, Oklahoma, and
this Note is to be construed according to the laws of the State of Oklahoma.

     Upon an Event of Default as defined in the Project Loan Agreement, in any
of the terms or conditions of this Note, the Project Loan Agreement, Mortgage,
Security Agreement, or any other instrument securing payment of this Note, at
the option of the Holder, the entire indebtedness hereby evidenced shall in
accordance with the terms of the Project Loan Agreement related hereto, become
due, payable and collectible then or thereafter as the Holder may elect,
regardless of the date of maturity hereof. Notice of the exercise of such option
is hereby expressly waived.

     The Maker agrees that if, and as often as, this Note is placed in the hands
of an attorney for collection or to defend or enforce any of the Holder's rights
hereunder, the Maker will pay to the Holder its reasonable attorney's fees,
together with all court cost, and other expenses paid by such Holder.

     It is the intent of the Holder and the Maker to conform strictly to the
usury laws of the State of Oklahoma, and any interest on the principal sum
hereof in excess of that allowed by such usury laws shall be subject to
reduction to the maximum amount of interest allowed under such laws. If any
interest in excess of the maximum amount of interest allowable by such usury
laws is inadvertently paid to the Holder, at any time, any such excess interest
shall be refunded by the Holder to the party or parties entitled to the same
after receiving notice of payments of such excess interest.

     The Maker and the endorsers, sureties, guarantors, and all other persons
who may become liable for all or any part of this obligation severally waive
presentment for payment, protest and notice of nonpayment. Such parties consent
to any extension of time of payment hereof, whether one or more, any renewal
hereof, whether one or more, and any release of any party liable for payment of
this obligation. Any such extension, renewal or release may be made without
notice to any such party and without discharging such party's liability
hereunder.

     The records of the Holder shall be prima facie evidence of the amount owing
on this Note.

                                       3

     IN WITNESS WHEREOF, the Maker has executed this instrument as of this 14th

     proceeding with the power of sale, may at its option declare the whole
     amount of the indebtedness secured by this Mortgage remaining unpaid,
     immediately due and payable without notice, and proceed by suit or suits in
     equity or at law to foreclose this Mortgage. Appraisement of the Lease is
     hereby waived or not waived at the option of the Mortgagee, such option to
     be exercised at or prior to the time judgment is rendered in such judicial

                                       3

     foreclosure. The Lease may be sold as one parcel or in such parcels as the
     Mortgagee may elect unless otherwise provided by law.

obligation under the Lease, or under or by reason of this Mortgage, and the
Mortgagor hereby agrees to indemnify the Mortgagee against and hold it harmless
from any and all liability, loss or damage which it may or might incur under the
Lease, or under or by reason of this mortgage and of and from any and all claims
and demands whatsoever which may be asserted against it by reason of any alleged
obligation or undertaking on its part to perform or discharge any of the terms
of the Lease; should the Mortgagee incur any such liability, loss, or damage
under the Lease or under or by reason of this Mortgage, or in defense against
any such claims or demands, the amount thereof, including costs, expenses, and
reasonable attorney's fees, together with interest thereon at the then
applicable rate of the Note, shall be secured hereby and by the Security
Agreement, and the Mortgagor shall reimburse the Mortgagee therefor immediately
upon demand.

     11.  This Mortgage shall inure to the benefit of the successors and assigns
of the Mortgagee and shall bind the Mortgagor's successors and assigns. It is
specifically agreed that Mortgagee may assign this mortgage to any subsequent
holder of the Note.

     12.  All notices, demands or documents which are required or prescribed to
be given or served hereunder shall be in writing and shall be deemed given when
sent by registered or certified mail addressed to: Mortgagor at 16 South

of the Lessee not, without the prior written consent of the Financier, to lodge
any proof of debt or similar claim in respect of any debt or liability by the

Financieer any such debt or liability and any rights of proof or other rights or
benefits in respect thereof and any such security;

          (b)  if requested by the Financier, to lodge a proof of debt or

     46.  Reinstatement of Guarantor's Liability.  If any payment made to the
Financier by or on behalf of the Lessee or Guarantor is subsquently avoided by
any statutory provision or otherwise, such payment shall be deemed not to have
discharged the Guarantor's liability under this Guarantee and in such event the

if such payment had not been made.

          limitation, any legal fees on a full indemnity basis or solicitor and
          own client basis, whichever is the higher).

     (d)  The Customer hereby authorises GE Capital to enter any premises
          occupied by the Customer during ordinary business hours for the

          default, breach or event and the taking of possession of the Relevant
          Equipment by GE Capital shall not constitute a waiver of any claim of

3.18 SURRENDER

     (a)  Upon the Expiry Date in respect of any Equipment, the Customer shall
          at its own cost deliver that Equipment to a place designated in

          is to be delivered a reasonable time prior to the Expiry Date.

     (b)  Upon the receipt of the Equipment by GE Capital following the Expiry
          Date applicable to that Equipment or upon receipt by GE Capital of any
          Equipment (except in the case of termination pursuant to Clause
          3.14(b) hereof) upon the prior termination for any reason (including
          voluntary return of that Equipment with the consent of GE Capital) of
          the Customer's right to possession of that Equipment, GE Capital shall
          either:

          (i)  dispose of that Equipment either in whole or in part at public
               auction or by private auction or treaty or by all or any of such

          (ii) obtain a valuation of the Equipment as described in Clause
               3.18(d).

     (c)  If the net proceeds of such a disposal (after allowing for all costs
          and expenses relating to the receipt by GE Capital of the Equipment
          and its disposal, including storage and after deducting any GST) is
          less than the Residual Value for that Equipment (as stated in the
          Relevant Supplement) or an amount determined in accordance with Clause
          3.16, whichever is the greater," the Customer shall forthwith upon
          demand by GE Capital pay to GE Capital by way of capital indemnity the
          amount of any such deficiency (which monies are in addition to

                                       21
<PAGE>
 
          any other moneys or damages payable to GE Capital by the Customer).

     (d)  If GE Capital is unable to effect a disposal of the Equipment at what
          it considers to be a reasonable price within two (2) months of the
          date of the same being received into the possession of GE Capital, GE
          Capital shall obtain a valuation of the Equipment by an independent
          valuer selected by GE Capital and the provisions of Clause 3.18(c)
          shall apply as if the Equipment had been sold at the date of the
          valuation for a cash price equal to the amount of the valuation less
          the expenses incidental to the receipt valuation and storage in the
          meantime. Such a valuation may be made at any time. If it is not
          possible to value the Equipment, the valuer may value goods of a
          similar description and such value shall be taken as the value of the
          Equipment.

     (e)  Nothing herein or in any Supplement shall be construed as giving the
          customer any right or option to purchase the Equipment for the
          Residual Value or the current market value or any other value
          whatsoever.

          and that the Customer has satisfied himself as to the condition and
          suitability of Equipment and its fitness for the Customer's purposes.

          the suitability or fitness of any Equipment or services for any
          particular application, other than those expressly referred to herein,
          are hereby expressly excluded.

     (c)  To the extent permitted by law, GE Capital shall under no
          circumstances be liable in any way whatsoever to the Customer nor
          shall the Customer have any remedy, in

          contractual, tortious, statutory, or otherwise) for any special,
          incidental, indirect, or consequential damages or for any loss of
          profits, revenue or data even if GE Capital should have been advised
          of the possibility of such potential loss or damage. The Customer is
          solely responsible for the protection and backup of all data and
          software used in conjunction with the Equipment.

     (b)  the due and punctual observance and performance by the Customer of all
          its other liabilities and obligations (whether present or future or

     be incurred by GE Capital by reason of any such default (all of which
     moneys, liabilities and obligations specified in this Clause 2 are
     hereinafter referred to as the Customer's Obligations").

3.   This Guarantee is a continuing guarantee and shall be irrevocable and
     remain in effect until the whole of the Customer's Obligations have been
     paid or satisfied.

4.   Where two or more persons are guarantors hereunder, the obligations on the
     part of the Guarantor hereunder shall bind those persons and every two or
     greater number of them jointly and each of them severally and GE Capital
     may at any time proceed against either or both or any or all of those
     persons.

5.   The Guarantor's Obligations hereunder shall be principal obligations and GE
     Capital shall be entitled to demand payment hereunder from the Guarantor
     without being required to first proceed against the Customer or enforce any
     security it may hold with respect to the Customer's Obligations.

6.   The Guarantor's obligations hereunder shall not be effected or prejudiced
     by:

     (a)  any release or variation of the Agreement or the replacement of the
          Agreement with any new Agreement or instrument; or

                                       30
<PAGE>
 
     (b)  any time, credit or other indulgence given or agreed to be given by GE
          Capital to the Customer in respect of its obligations under the
          Agreement; or

     (c)  any other guarantee or security which GE Capital may now or hereafter
          hold in respect of the Customer's Obligations or any release or
          variation thereof or by reason of any other person becoming or not
          becoming a Guarantor of the Customer's Obligations; or

     (d)  the death, mental incapacity, winding up or bankruptcy of the Customer
          or any Guarantor; or

     (e)  any other act, matter or omission which, but for its provision, might
          or would operate to discharge, effect or otherwise prejudice the
          Guarantor's liability hereunder.

7.   The Guarantor shall not claim the benefit of any security now or hereafter
     held by GE Capital for the Customer's Obligations until the whole of the
     Customer's Obligations have been paid or satisfied.

8.   Upon the winding up or bankruptcy of the Customer, until GE Capital has
     received 100 cents in the dollar in respect of the Customer's Obligations:

     (a)  the Guarantor shall not, without the prior written consent of GE
          Capital, lodge any proof of debt in respect of any debt or liability
          owed by the Customer to the Guarantor on any account whatsoever or
          enforce any security held by the Guarantor from the Customer but shall
          hold in trust for GE Capital any such debt, rights of proof and
          security;

     (b)  if requested by GE Capital, the Guarantor shall lodge a proof of debt
          in respect of any such debt and enforce any such security and execute
          and do all such documents and things as GE Capital may require to
          enable GE Capital to receive the benefit of or arising from any such
          proof or security; and

     (c)  the Guarantor hereby irrevocably appoints GE Capital its attorney to
          execute and deliver and do such documents and things which GE Capital
          may think desirable for giving effect to this Clause.

9.   GE Capital may release or otherwise deal with any security now or hereafter
     held by GE Capital for any of the Customer's Obligations and/or the
     Guarantor's obligations hereunder without releasing or prejudicing the
     liability of the Guarantor under this Guarantee and the Guarantor shall not
     hold GE Capital responsible for any loss or damage howsoever

                                       31
<PAGE>
 
     suffered by the Guarantor as a result of any such release or dealing.

10.  This Guarantee shall continue to be effective or shall be reinstated, as
     the case may be, if at any time payment of any moneys payable under the
     Agreement or under this Guarantee are avoided or must be repaid or
     restored, either in whole or in part, by GE Capital to the Customer or to
     the Guarantor (or any official manager, trustee in bankruptcy or
     liquidator) by reason of preference or for any other reason whatsoever and
     the liability of the Guarantor hereunder shall extend to all such moneys
     and such payment shall be deemed not to have discharged the Customer's
     Obligations or the Guarantor's Obligations hereunder and GE Capital shall
     have the same rights against the Guarantor as if that payment had not been
     made.

11.  The Guarantor agrees that a certificate signed by or on behalf of GE
     Capital stating that the amount or the amounts due to GE Capital by the
     Customer and/or the Guarantor hereunder on any account whatsoever shall, in
     the absence of manifest error, be conclusive evidence of the facts stated
     therein.

12.  Any notice required or permitted to be given hereunder to the parties
     hereto shall be deemed to have been given if in writing and delivered in
     person or sent by telegram or telex or mailed by first-class, registered or
     certified mail, postage pre-paid and addressed to the Guarantor or GE
     Capital, as the case may be, at their respective addresses set forth
     herein.

13.  No failure or delay of GE Capital to exercise any of its rights hereunder,
     or to insist on strict compliance by the Guarantor of any of its
     obligations hereunder, shall constitute a waiver or variation of the rights
     of GE Capital to demand exact compliance with the terms hereof.

14.  The Guarantor hereby waives in favour of GE Capital all rights as surety so
     far as necessary to give effect to anything contained in this Guarantee.

15.  GE Capital may at any time during the currency of this Guarantee assign the
     benefit of this Guarantee and its rights hereunder. The Guarantor shall not
     assign or novate its rights or obligations hereunder without the prior
     written consent of GE Capital.

16.  This Guarantee shall be construed in accordance with and be governed by the
     laws in force in New Zealand and the Guarantor hereby submits to the non-
     exclusive jurisdiction of the New Zealand Courts.

applied in reduction or satisfaction of any indebtedness of the Lessee to the
Lessor under this Agreement but the Lessee shall have no claim to or interest in
any further surplus.

16.  FAILURE TO RETURN EQUIPMENT ON EXPIRATION OR TERMINATION

If upon the termination or expiration of the Lease the Lessee fails to return
the Equipment to the Lessor in accordance herewith and the Lessor has not then
otherwise regained possession thereof, the Lessee shall pay to the Lessor on
demand by way of liquidated or ascertained damages the Residual Value of the
Equipment.  If the Lessor subsequently obtains possession of the Equipment the
Lessor shall apply the sum representing the Value of the Equipment in reduction
or satisfaction of the Lessee's indebtedness under this Lease.  Any payment by
the Lessee under his or the preceding clause shall be in addition to all other
amounts payable hereunder and shall be to indemnify the Lessor against a capital
loss it would otherwise suffer.  Notwithstanding the terms of clause 15 or
otherwise under this clause, where this Lease is terminated prior to the
expiration of the term set out in the Schedule, the Residual Value shall be the
present value at the date of termination of the originally stated Residual
Value, such present value being calculated by discounting the originally stated
Residual Value on a monthly basis at the Rebate Rate over the period in whole
months by which the date of termination is brought forward pursuant to this
clause.

17.  PAYMENTS ON EARLY TERMINATION

Upon termination of this Lease (whether pursuant to clause 12 hereof, clause 13
hereof or otherwise) prior to the expiration of the Term the Lessee shall in
addition to any amounts payable under clauses 15 and 16 hereof and in order to
indemnify the Lessor for the loss sustained in respect of rent installments not
then accrued, pay to the Lessor on demand a liquidated debt equal to the sum of
the present values at the date of such termination of each of the installments
of rent not then accrued but which would thereafter have accrued if this
Agreement had not been terminated prior to the expiry of the term.  Such present
value shall be ascertained by discounting each such installment of rent on a
monthly basis at the Rebate Rate over the period in whole months by which the
date for payment of each installment is brought forward by virtue of this
clause.

18.  HOLDING OVER

If the Lessee continues in possession of the Equipment after the expiration of
the Term or the termination of this Agreement:

(a)  without the Lessor's consent -- the Lessee shall pay to the Lessor by way
     of liquidated damages for detention a daily sum equal to the amount
     obtained by dividing the amount of the last installment of Rent specified
     in the Schedule by the number of days in the last rental period; or

(b)  with the Lessor's written consent -- the Lessee shall until the return of
     the goods pay to the Lessor a daily rental equal to the amount obtained by
     dividing the amount of the last installment of Rent specified in the
     Schedule by the number of days in the last rental period,

and in either case the Lessee shall carry out and abide by the terms of this
Agreement as far as applicable.

19.  SUPPLIER'S WARRANTIES

     To the extent possible and permissible the Lessor hereby assigns to the
Lessee during the term of this Agreement, so long as no Event of Default is
subsisting, the benefit of all claims and rights including warranties in respect
of the Equipment which the Lessor may have against any Supplier or any sub-
contractor of any Supplier and the Lessee shall, at its own cost, assert and
enforce all such claims and rights.

     The Lessee shall indemnify and keep the Lessor indemnified from and hold
the Lessor harmless against all loss, cost and damage suffered or incurred by
the Lessor arising out of the Lessee exercising its powers and performing its
obligations under this Clause.

20.  EXCLUSION OF WARRANTIES

(a)  The Lessee acknowledges and agrees to the full extent permitted by law
     that:

     (i)   in deciding to enter into this Agreement the Lessee has not relied in
           any way on the Lessor's skill or judgment or on any statements,
           representations or warranties made by the Lessor;

     (ii)  the Lessee will itself prior to any Equipment becoming subject to
           this Agreement have selected and examined it and satisfied itself as
           to its compliance with its description as well as its condition,
           suitability and fitness for the Lessee's purpose and the validity of
           any manufacturer's warranties or guarantees and in every other
           necessary respect whatsoever;

                                       22

           safety of or title to the Equipment; and

     (v)   any provisions which may be implied in this Agreement under any law
           shall not be implied in this Agreement except insofar as such
           provisions are not capable of being excluded under any such law and
           any liability of the Lessor in respect of any such non-excludable
           provision is limited to the full extent permitted by law.

(b)  Notwithstanding clause 20(a), if the Lessee is a consumer, it shall have

     liable for a breach of a condition or warranty implied by Division 2 of
     Part V of the Act (not being a condition or warranty implied by Section 69
     of the Act) the liability of the Lessor for such breach including any
     consequential loss which the Lessee may sustain shall, subject to Section
     68A(2) of the Act, be limited to one of the following as determined by the
     Lessor:

     (i)   the replacement of the Equipment or the supply of equivalent
           Equipment; or

     (ii)  the payment of the cost of replacing the Equipment or of acquiring
           equivalent Equipment.

     References to specific provisions of and circumstances arising under the
     Act are intended to include references to equivalent or similar provisions
     of and circumstances arising under any State or Territory enactment.

(c)  Subject to any legislation to the contrary, the Lessee acknowledges and
     agrees that:

     (i)   the Lessor shall not be liable to the Lessor for any liability claim
           loss damage or expense of any kind or nature (including any
           consequential loss) caused directly or indirectly by the Equipment or
           any inadequacy thereof for any purpose or any defect therein or by
           the use or condition thereof;

     (ii)  the Lessor shall be under no liability with respect to any statements
           regarding the Lessee's rights or position with respect to any law
           relating to taxation or any other matter;

                                       23

           by any loss or damage whatsoever to or breakdown or defect in the
           Equipment; and

interrupt, occupy or hinder Koch's adjacent businesses; provided that failure to

expenditure at the rate of 18% per year or the maximum applicable rate permitted
by law, whichever is less, shall be due and payable within ten (10) days after
notice thereof by Koch to DSN, and the failure of DSN promptly to pay such sums
shall enable Koch to exercise all of its other remedies under this Lease.

[If Mortgagee named above is not ORIX Credit Alliance, Inc., Mortgagor
acknowledges notice of the intended assignment hereof to ORIX Credit Alliance,
Inc. (said assignee hereinafter called "Mortgagee") and upon such assignment,
Mortgagor agrees not to assert against Mortgagee any defense, set-off,
recoupment, claim or counterclaim which Mortgagor may have against the Mortgagee
named above and any assignee hereof prior to Mortgagee, whether arising
hereunder or otherwise.]

                                  WITNESSETH:

     1.   To secure the prompt payment, with interest therein, performance and
fulfillment of any and all Mortgage Obligations (as hereinafter defined) of
Mortgagor to Mortgagee, which is hereby confessed and acknowledged, Mortgagor
hereby grants, assigns, transfers, bargains, conveys, confirms, pledges,
mortgages and grants to Mortgagee a security interest in all and singular, the
goods, chattels and property described in the annexed Schedule A and any and all
documents, instruments, chattel paper, goods, machinery, contract rights,
equipment, fixtures, and insurance in which Mortgagor now or hereafter has any
right or interest [A] (all of the foregoing, together with all accessions,
attachments, replacements, substitutions and accessories thereto now or
hereafter belonging to Mortgagor, wherever located, and all proceeds, and any
distribution thereof and any insurance thereon, products and rents therefrom
collectively called "Collateral"), to have and to hold the same unto Mortgagee
forever; provided, however, that if Mortgagor shall fully, timely and faithfully
pay, perform and fulfill the Mortgage Obligations, time being of the essence
hereof, then this Mortgage shall be void, but otherwise shall remain in full
force and effect. Mortgagor grants Mortgagee a security interest in the
Collateral to secure the Mortgage Obligations.

     2.   The term "Mortgage Obligations" as used herein shall mean and include
any and all loans, advances, payments, extensions of credit, endorsements,
guaranties, benefits and financial accommodations heretofore and/or hereafter
made, granted or extended by Mortgagee or which Mortgagee has or will become
<PAGE>
 
obligated to make, grant or extend to or for the account of Mortgagor, and any
and all interest, obligations, liabilities, indebtedness, charges and expenses
heretofore and/or hereafter chargeable against Mortgagor by Mortgagee or owing
by Mortgagor to Mortgagee or upon which Mortgagor may be and/or has become
liable as endorser or guarantor, and any and all renewals or extensions of any
of the foregoing [B] given to or received by Mortgagee directly by Mortgagee
directly from Mortgagor and the prompt performance and fulfillment by Mortgagor
of all of the terms, conditions, promises, covenants, provisions and warranties
contained in this Mortgage and in the note secured hereby.

     3.   Mortgagor covenants and warrants to Mortgagee and agrees that the
Collateral described in the annexed Schedule A is in the possession of Mortgagor
at its principal place of business (which is Mortgagor's address shown above),
unless a different location is specifically shown on Schedule A for any one or
more items, that all of the Mortgage Obligations are acknowledged and declared
to be secured by this Mortgage and that Mortgagor will fully and faithfully pay,
perform and fulfill all of the Mortgage Obligations, with late charges thereon
from and after maturity of any unpaid installment of the Mortgage Obligations,
whether by acceleration or otherwise, at the rate of 1% per day until the
Mortgage Obligations are collected by the Mortgagee in full. Any interest rate,
fee or charge ("rate") charged or to be charged or provided for in any way
hereunder or under any document, note or instrument given in connection with any
of the Mortgage Obligations shall not in any event or contingency exceed any
maximum permitted by applicable law and any such rate shall be deemed hereby
amended accordingly. Any sums collected with respect to any rate in excess of
any maximum shall be applied to reduce the principal sum owing under the
Mortgage Obligations. Mortgagor further covenants and agrees with and warrants
to Mortgagee that:

     (a)  Mortgagor is the lawful owner of the Collateral and represents and
warrants to Mortgagee that Mortgagor has paid all applicable sales, use or other
taxes due in connection with the sale, purchase, ownership, possession or use of
the Collateral and shall indemnify Mortgagee from and against any loss, cost or
expense, including penalties, interest and other charges of any kind in
connection with or arising from [C] purchase, ownership, possession or use of
the Collateral, and has the sole right and lawful authority to make this
Mortgage; the Collateral and every part thereof is free and clear of all liens
and encumbrances of every kind, nature and description (except any held by
Mortgagee); and Mortgagor will warrant and defend the Collateral against all
claims and demands of all persons and will not permit any circumstances to exist
under which the Mortgagee may lose its lien on the Collateral.

     (b)  Mortgagor will keep the Collateral free and clear of all attachments,
levies, taxes, liens and encumbrances of every kind; 

                                       2
<PAGE>
 
Mortgagor, at its own cost and expense, will maintain and keep the Collateral in
good repair, [D] will not waste nor abuse nor destroy the same or any part
thereof and will not be negligent in the care and use thereof; and Mortgagor
will not sell, assign, mortgage, lease, pledge or otherwise dispose of the
Collateral without the prior written consent of Mortgagee. Mortgagee is hereby
authorized to file one or more financing statements and/or a reproduction hereof
as a financing statement. Mortgagor hereby irrevocably appoints Mortgagee as the
true and lawful Attorney-in-Fact of Mortgagor, coupled with an interest, with
full power in Mortgagor's name, place and stead to execute financing statements
on Mortgagor's behalf and to do any and all other acts on Mortgagor's behalf
necessary or helpful to perfect Mortgagee's security interest in the Collateral
pursuant to the Uniform Commercial Code or other applicable law.

     (c)  Mortgagor will insure the Collateral in the name of the Mortgagee
against loss or damage by fire and extended coverage perils, theft, burglary,
pilferage, collision and also, where requested by Mortgagee, against other
hazards, with companies, in amounts and under policies (each containing a
standard breach of warranty clause) acceptable to Mortgagee, the proceeds to be
payable to Mortgagee [E] and all premiums thereon shall be paid by Mortgagor and
[F] delivered to Mortgagee. Mortgagee shall have the right, but not the
obligation, to provide insurance for its interest and charge Mortgagee
Mortgagor's cost for such insurance. Mortgagor hereby irrevocably appoints
Mortgagee as Mortgagor's Attorney-in-Fact to make claim for, receive payment of
and execute and endorse all documents, checks or drafts received in payment for
any loss or damage under any of said insurance policies and to execute any
documents or statements referred to herein.

     (d)  Mortgagor will not remove the Collateral from within the 48 contiguous
States of the United States or its present locations without the prior written
consent of Mortgagee nor change its present business locations without at least
thirty days prior written notice to Mortgagee and at all times will allow
Mortgagee or its representatives free access to and right of inspection of the
Collateral, which shall remain personalty and not become a part of any realty,
and nothing shall prevent Mortgagee from removing same or so much thereof as
Mortgagee, in its sole discretion may determine, from any premises to which it
may be attached and/or upon which it may be located upon breach of this
Mortgage; Mortgagor agreeing to deliver to Mortgagee appropriate waivers,
satisfactory to Mortgagee, of owners and of mortgagees of any such premises.

     (e)  Mortgagor shall comply (so far as may be necessary to protect the
Collateral and the lien of this Mortgage thereon) with all of the terms and
conditions of leases covering the premises wherein the Collateral may be located
and with any orders, ordinances, laws or statutes of any city, state or other
entity

                                       3
<PAGE>
 
having jurisdiction over the premises or the conduct of business thereon, and,
where requested by Mortgagee, will correct any defects or execute any written
instruments and do any other acts necessary to more fully effectuate the
purposes and provisions of this instrument.

     (f)  Mortgagor will indemnify and save Mortgagee harmless from all losses,
costs, damages, liabilities or expenses, including reasonable attorneys' fees,
that Mortgagee may sustain or incur to obtain or enforce payment, performance or
fulfillment of any of the Mortgage Obligations or in the enforcement or
foreclosure of this Mortgage or in the prosecution or defense of any action or
proceeding either against Mortgagor or against Mortgagee concerning any matter
growing out of or connected with this Mortgage and/or any of the Mortgage
Obligations and/or any of the Collateral.[G]

     (g)  If Mortgagor is a corporation, the execution of this Mortgage has been
duly consented to and authorized by its Board of Directors. Mortgagor agrees to
deliver to Mortgagee evidence thereof satisfactory to Mortgagee immediately upon
request.

     4.   This Mortgage may be assigned along with any and all Mortgage
Obligations, without notice to Mortgagor, and upon such assignment Mortgagor
agrees not to assert against any assignee hereof any defense, set-off,
recoupment, claim, counterclaim or cross-claim which Mortgagor may have against
Mortgagee, whether arising hereunder or otherwise, and such assignee shall be
entitled to at least the same rights as Mortgagee. MORTGAGOR AND MORTGAGEE
HEREBY DESIGNATE AND APPOINT EDWIN M. BAUM, ESQ. AND C-A CREDIT CORP., BOTH OF

     5.   If Mortgagor shall default in the prompt payment, performance or
fulfillment of any of the Mortgage Obligations,[H] or if Mortgagor shall cease
doing business, or become insolvent, or make an assignment for the benefit of
creditors, or if proceedings under any Bankruptcy Act or for the appointment of
a receiver, trustee, liquidator or custodian for Mortgagor or any of Mortgagor's
property shall be commenced by or against Mortgagor, or if Mortgagor shall fail
to punctually and faithfully fulfill, observe or perform any of the terms,
conditions, promises, covenants, provisions and warranties contained in this
Mortgage [I] or if any of the warranties, covenants or representations made to
Mortgagee be or become untrue or incorrect in any adverse respect, or if
Mortgagee at any time deems the security afforded by this Mortgage unsafe,
inadequate or at any risk, then in any such event the indebtedness under all
Mortgage Obligations shall at once, at the option of Mortgagee, and to the
extent permitted by applicable law, become immediately due and payable without
notice to Mortgagor, and in such event it shall be lawful for Mortgagee to take
possession of the Collateral, at any time, wherever it may be, and to enter any
premises, with or without process of law, and search for, take possession of,
remove, or keep and store the Collateral on said premises until sold, without
liability for trespass nor charge for storage, and to sell the Collateral or any
part thereof and all of Mortgagor's equity of redemption therein at public or
private sale, for cash or on credit, and on such terms as Mortgagee may in its
sole discretion elect, in such county and at such places as Mortgagee may elect
and without having the Collateral at the place of sale; Mortgagee may bid or
become the purchaser at any such sale and Mortgagor waives any and all rights of
redemption from any such sale. Any public sale will be deemed commercially
reasonable if notice thereof shall be mailed to Mortgagor at least 10 days
before such sale and advertised in at least one newspaper of general circulation
in the area of the sale at least twice prior to the date of sale and if upon
terms of 25% cash down with the balance payable within 24 hours; and any private
sale shall be deemed commercially reasonable if notice thereof shall be mailed
to Mortgagor at least 14 days before the sale date stated therein and credit
given for the full price stated, less reasonable attorneys' fees. In light of
Mortgagor's obligations to maintain the Collateral, Mortgagee shall not be
required to refurbish, repair or otherwise incur any expenses in preparing
Collateral for sale but may sell its interest therein on an "as-is", "where-is"
basis. The proceeds of any public sale shall be applied first to pay all costs,
expenses and charges for pursuing searching, taking, removing, keeping,
advertising and selling the Collateral, including reasonable attorneys' fees and
second to the payment of any of the Mortgage Obligations returning the overplus,
if any, to Mortgagor, who shall remain liable to Mortgagee for any deficiency
plus late charges thereon as provided above. Mortgagor expressly waives any
right to notice or hearing in any action to recover possession of any or all of
the Collateral. In any action in the nature of replevin or sequestration,
Mortgagor agrees that 

                                       5
<PAGE>
 
if it contests such action it will post a bond written by a national insurance
company authorized to execute such bonds in the jurisdiction of such
proceedings, such bond to be no less than the value of the subject matter of
such replevin or the unpaid balance then owing to Mortgagee, whichever is less.
Any notices relating hereto shall be in writing and effective when delivered in
person to an officer of the party to whom addressed or mailed by certified mail
to such party at its address specified herein or at such other address as may
hereafter be specified by like notice by either party to the other. Reasonable
notification hereunder shall be any notification given or sent at least five (5)
days prior to the event for which such notification is sent. MORTGAGOR AND
MORTGAGEE HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY AND ALL
RIGHT TO A TRIAL BY JURY OF ANY AND ALL CLAIMS, DEFENSES, COUNTERCLAIMS,
CROSSCLAIMS AND SET-OFF OR RECOUPMENT CLAIMS ARISING DIRECTLY OR INDIRECTLY
BETWEEN OR AMONG THEM AND/OR INVOLVING ANY PERSON OR ENTITY CLAIMING ANY RIGHTS
ACQUIRED BY, THROUGH OR UNDER ANY PARTY AND FURTHER WAIVES ANY AND ALL RIGHT TO
CLAIM OR RECOVER ANY PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER
THAN, OR IN ADDITION TO, ACTUAL DAMAGES.

     6.   If, after default by Mortgagor under the Mortgage Obligations,
Mortgagee fails to demand full payment, performance or fulfillment or otherwise
proceed, such failure shall not be deemed a waiver of the right of Mortgagee
subsequently to make demand for immediate payment, performance and fulfillment
of the Mortgage Obligations, or to take immediate possession of the Collateral,
or to foreclose this Mortgage at any time or to proceed otherwise; and the
acceptance by Mortgagee of any payment subsequent to such default shall not be
deemed a waiver of any of Mortgagee's rights. No delay or failure on the part of
Mortgagee in exercising any right, privilege, remedy or option hereunder shall
operate as a waiver of such or of any other right, privilege, remedy or option,
and no waiver whatever shall be valid unless in writing, signed by an officer of
Mortgagee and then only to the extent therein set forth. This Mortgage cannot be
changed or terminated orally. Mortgagee shall have the right to enforce any one
or more remedies available to it successively, alternately or concurrently. Only
a writing, signed by an officer of Mortgagee [J] shall be effective, but only to
the extent therein specifically set forth, to change, modify or terminate any
Mortgage Obligation, this Mortgage or any other agreement between Mortgagor and
Mortgagee.

     7.   All of the rights, remedies, options, privileges and elections given
to the original Mortgagee hereunder shall enure to the benefit of Mortgagee, any
transferee or holder of this Mortgage, and their respective successors and
assigns; and all the terms conditions, promises, covenants, provisions and
warranties of this Mortgage shall enure to the benefit of and shall bind the
representatives, successors and assigns of the respective parties. Any and all
security interests granted to Mortgagee shall attach to 

                                       6
<PAGE>
 
any and all proceeds and products. Each person signing this Mortgage warrants
full authority to sign for the party named.

     8.   Some of the Collateral may be in the hands of Mortgagor under one or
more security agreements which are or may be held by Mortgagee and with respect
to such Collateral, this Mortgage is only of any equity that Mortgagor may now
or in the future have in such Collateral and Mortgagee by accepting this
Mortgage shall not in any manner be considered as having waived any security
interest arising independently of this Mortgage nor shall this Mortgage be
construed as adversely affecting any rights of Mortgage under any other security
agreement nor as a waiver of any of the terms and provisions of any other
security agreement, guaranty or endorsement, all of which shall remain and
continue in full force and effect.

     9.   Intending that each and every provision of this Mortgage be fully
effective and enforceable according to its terms, the parties agree that the
validity, enforceability and effectiveness of each provision hereof and the
obligations, rights and remedies of the Mortgagor and Mortgagee in any way
related to or arising under this Mortgage or under one or more Mortgage
obligation shall be governed by and construed in accordance with the laws of the
State of New York (excluding its choice of law rules), if any one or more
provisions hereof are in conflict with any statute or law and thus not valid or
enforceable, then each such provision shall be deemed null and void but only to
the extent of such conflict and without invalidating or affecting the remaining
provisions hereof. This contract shall be binding upon the heirs,
administrators, legal representatives and successors of the Mortgagor.

     10.  MORTGAGOR DOES HEREBY WAIVE, FOREGO AND AGREE NOT TO ASSERT ANY AND
ALL RIGHTS, CLAIMS AND DEFENSES, IF ANY, UNDER THE FEDERAL FAIR CREDIT REPORTING
ACT AND/OR UNDER ANY COMPARABLE STATE LAWS THAT MAY INURE TO THE BENEFIT OF
MORTGAGOR IN CONNECTION WITH THIS MORTGAGE. MORTGAGOR HEREBY RATIFIES AND
APPROVES THE OBTAINING BY MORTGAGEE OF ANY CREDIT REPORT RELATING TO MORTGAGOR
AND HEREBY AGREES THAT MORTGAGEE MAY HEREAFTER OBTAIN SUCH CREDIT REPORTS AS
MORTGAGEE IN ITS SOLE DISCRETION MAY DETERMINE.

     11.  This is subject to the additional terms and conditions in the Addendum
dated _____________.

     IN WITNESS WHEREOF, Mortgagor has caused these presents to be duly
executed, the day and year first above written.

                                LEASE AGREEMENT
                                ---------------

     This Lease Agreement made and executed on  March 7 , 1988, but and between
NORTHWEST FINANCIAL CORPORATION, a federally organized savings and loan

     The parties to this Lease Agreement agree as follows:

     1.   Agreement to Lease. Landlord hereby demises and leases to Tenant, and
          ------------------                                                   
Tenant hereby hires and takes from Landlord, the premises and the buildings and
improvements located thereon and the appurtenances thereto (including, without
limitation, adequate ways of ingress and egress directly between the building on
the premises and public roads, and the parking area for automobiles) situated in

(hereinafter referred to as the "Leased Premises").

     2.   Term. The term of the Lease Agreement shall be for a period of twelve
          ----                                                                 
(12) years from the date of this Lease Agreement and ending on March 6 , 2000,
unless this Lease Agreement is sooner terminated pursuant to the terms of this
Lease Agreement or the term hereof is extended pursuant to the terms of this
Lease Agreement.

     3.   Delivery of the Leased Premises. Notwithstanding any other provision
          -------------------------------                                     
hereof, Landlord covenants that actual possession of the Leased Premises shall
be delivered to Tenant as of the date of this Lease Agreement, free and clear of
all tenancies or other 
<PAGE>
 
claims, rights or, interests of occupancy, use, or any other inconsistent or
adverse claims, rights or interests.

     4.   Rent During Term. Subject to the terms of this Lease Agreement, Tenant
          ----------------                                                      
agrees to pay the Landlord rent for the Leased Premises, as follows:

          (a)  For the first year of this Lease Agreement, the annual rental to
be paid by Tenant to Landlord shall be $447,319 ("Base Rent"), payable in twelve
                                       --------                                 
equal monthly installments of $37,276.58 each, with each monthly installment
                              ----------                                    
payable on or before the 15th day of each month during the first year of this
Lease Agreement. For the purposes of this Lease Agreement, "first year of this
Lease Agreement" shall mean the twelve month period beginning on the date of
this Lease Agreement and ending March 6 , 1988.

          (b)  Within fifteen (15) days after the beginning of each year during
the term hereof after the first year of this Lease Agreement - the amount of the
annual rental to be paid by Tenant to the Landlord for such year shall be
calculated and determined, as follows ("Adjusted Annual Rental"): The Base Rent
less the amount or amounts received during the preceding year just ended by the
Landlord of all income, revenues or payments due to or as a result of or from
the oil and gas working interests listed in Exhibit B attached hereto and which
is incorporated herein by reference ("Oil and Gas Revenues"). Within ten (10)
days after the beginning of each year during the term hereof after the first
year of this Lease Agreement, the Landlord shall advise the Tenant of the amount
of 

                                       2
<PAGE>
 
the oil and Gas Revenues received by the Landlord during the preceding year just
ended and shall advise the Tenant of the Adjusted Annual Rental, if any, based
on the above calculation for such year. The Tenant shall pay to the Landlord the
Adjusted Annual Rental for such year in twelve (12) equal monthly installments
during said year, with each monthly installment payable on or before the 15th
day of each month during such year. If in calculating the Annual Adjusted Rental
for a particular year the oil and Gas Revenues for the preceding year just ended
is equal to or greater than the Base Rental, then no rental shall be payable to
the Landlord by the Tenant hereunder during such year, and the amount by which
such oil and Gas Revenues exceeds the Base Rent shall be carried forward and
added to the amount of Oil and Gas Revenues in calculating the Annual Adjusted
Rental for the next subsequent year. For the purposes of this Lease Agreement, a
"year" means a twelve month period beginning on March 7 and ending on March 6.

     5.   Covenant of Peaceful Possession. Landlord covenants and warrants that
          -------------------------------                                      
if Tenant shall discharge the obligations set forth in this Lease Agreement to
be performed by Tenant, Tenant shall peaceably have, hold and enjoy the quiet
and undisturbed possession of the Leased Premises, together with all the
appurtenances thereto, without hindrance, ejection, disturbance or molestation
by Landlord or any person or entity claiming through or under Landlord, or
otherwise, and free of any inconsistent or adverse claim, right or interest.

<PAGE>
 
     6.   Assignment and Sublease by Tenant. The Tenant may sublet the Leased
          ---------------------------------                                  
Premises or any portion thereof covered by this Lease Agreement and may assign
this Lease Agreement. If Tenant does so sublet the Leased Premises or assign
this Lease Agreement, Tenant shall remain liable as guarantor hereunder in
connection with the obligations that the Tenant is to perform under this Lease
Agreement.

     7.   Use of Premises. Tenant may use the Leased Premises for the purpose of
          ---------------                                                       
operating a manufacturing operation, distribution center and/or for offices, or
any other related business (landlord hereby warranting that such uses are lawful
and permissible), and Tenant agrees not to use or knowingly permit the Premises
to be used for any unlawful purposes.

          ---------------------                                             
accepts the Leased Premises in its existing condition. Upon termination of this
Lease Agreement pursuant to the terms hereof, Tenant shall repair any material
damage to the interior of the buildings and improvements on the Leased Premises
caused by Tenant's breach of this Lease Agreement, ordinary wear and tear and
damages due to structural elements excepted; provided, further, that if the
Landlord is obligated to make repairs to the Leased Premises under the terms of
this Lease Agreement but fails to make such repairs, Tenant shall not be
obligated to make such repairs upon termination of this Lease Agreement (it
being understood that this proviso on Landlord's repair obligation shall in no
event be deemed to be in substitution for, or in limitation,

     17.  General Liability Insurance. Tenant shall obtain and maintain
          ---------------------------                                  
throughout the term of this Lease Agreement, at Tenant's expense, general
liability insurance in connection with the Leased Premises written by an
insurance company of recognized responsibility. The coverage of such general
liability insurance as it relates to the Leased Premises shall be for at least
One Million Dollars ($1,000,000) on account of injuries per occurrence. Such
general liability insurance policy as it relates to the Leased Premises shall
contain a provision requiring the insurer to give written notice of cancellation
to Landlord at least ten (10) days prior to cancellation. Such general liability
insurance as it relates to the Leased Premises shall name Landlord as an
additional insured as its respective interest may appear. Tenant shall supply to
Landlord upon the execution of this Lease Agreement a certificate of insurance
issued by the insurance carrier of Tenant showing that such insurance is in full
force and effect.

     Notwithstanding the above, Tenant may, at its option, self insure the
general liability in connection with the Leased Premises in lieu of obtaining
general liability insurance on the Leased Premises from an insurance company. In
the event that the Tenant does self-insure such general liability in connection
with the Leased Premises (i) Tenant shall have no obligation to obtain 

                                       9
<PAGE>
 
general liability insurance written by an insurance company during the period
that Tenant does self-insure such general liability and (ii) Tenant shall
indemnify the Landlord against, and hold Landlord harmless from, and all claims,
demands, actions, proceedings or liabilities incurred or to be incurred by the
Landlord as a result of an occurrence (as defined below) on the Leased Premises
that occurs during the period that the Tenant is self-insuring such general
liability on the Leased Premises and that results in bodily injury or property
damage to a third party not a party hereto. For the purposes of this Section 17,
"occurrence" means an accident which results in bodily injury or property
damage. If the Tenant does decide to self-insure the general liability in
connection with the Leased Premises, the Tenant agrees to give the Landlord
written notice of its decision no less than ten (10) days prior to the time that
Tenant will begin to self-insure such general liability.

     18.  Fire and Extended Property Damage.
          --------------------------------- 

          (a)  Subject to the terms hereof, during the term of this Lease
Agreement, the Tenant will keep insured any and all buildings and improvements
upon the Leased Premises against all loss or damage by fire, windstorm and
extended coverage, which said insurance will be maintained in an amount not less
than the full replacement value thereof. All of such policies of insurance
relating to the buildings and improvements on the Leased Premises shall name the
Tenant and Landlord as the insureds and shall fully protect both the Landlord
and the Tenant as their respective interests may appear. In the event of damage
to or destruction of 

                                       10
<PAGE>
 
the said buildings or improvements an the Leased Premises by fire, windstorm, or
other casualty for which insurance shall be payable and as often as such
insurance money shall have been paid to the Landlord and the Tenant for damages
to or destruction of the buildings and improvements on the Leased Premises, said
sums so paid shall be deposited in a joint account of the Landlord and the
Tenant in a bank or savings and loan satisfactory to the Tenant ("joint
account"), and such funds in the joint account shall be made available to the
Tenant for the construction or repair, as the case may be, of any buildings or
improvements located on the Leased Premises damaged or destroyed by fire,
windstorm, or other casualty, and shall be paid out by the Landlord and the
Tenant from said joint account from time to time on the estimate of the Tenant,
certifying that the amount of such estimate is being applied to the payment of
the reconstruction or repair. Tenant shall have no obligation to make such
repairs to or restoration of such damaged buildings and improvements located on
the Leased Premises the cost of which exceeds that portion of the insurance
proceeds made available to Tenant to make such repairs or restore such damaged
buildings and improvements on the Leased Premises.

          (b)  The foregoing notwithstanding, in the event the insurance
proceeds are the sum of $100,000 or less, then such proceeds shall be paid
directly to the Tenant without the necessity of creating the joint account, and
Tenant shall use such funds to make the replacements or repairs to the damaged
buildings and improvements on the Leased Premises.

                                       11
<PAGE>
 
          (c)  Any excess of money received from insurance remaining in the
joint account after the reconstruction or repair of such damaged buildings or
improvements on the Leased Premises shall, if the Tenant is not in default under
this Lease Agreement, be paid to Tenant. If the Tenant has not begun to restore
or repair the damaged buildings and improvements located on the Leased Premises
using the proceeds in the joint account for such repairs or restoration within a
period of 120 days from the date of receipt of such casualty, or such extended
period of time as agreed to in writing by both the Tenant and the Landlord, the
Tenant may, at its option, terminate this Lease Agreement and in the event of
such termination by Tenant the proceeds in the joint account shall be paid to
Landlord.

          (d)  If any mortgagee holding a mortgage on the Leased Premises
elects, in accordance with the terms of such mortgage, to require that all or
any part of the proceeds of such insurance paid as a result of damages to the
buildings and improvements located on the Leased Premises be paid to or retained
by the mortgagee, then such payment shall be made, but in such event, the
Landlord shall pay into the joint account referred to in subparagraph (a) of
this Section 18 that amount of the insurance proceeds paid to or retained by
mortgagee. In the event that such mortgagee elects such insurance proceeds be
paid to it in accordance with the terms of such mortgage and the Landlord fails
or refuses, for any reason whatsoever, to pay into such joint account that
amount of such insurance proceeds paid to or retained by the mortgagee within 30

                                       12
<PAGE>
 
days from the date of notification from the mortgagee of the mortgagee's
election to retain or have paid to it such insurance proceeds, in whole or in
part, the Tenant may, at its option, terminate this Lease Agreement.

          (e)  The policies of insurance required to be maintained by the Tenant
pursuant to this Section 18 may be carried by the Tenant under blanket policies
maintained by the Tenant. Such policies may provide for such deductible amounts
as are customarily provided for in insurance maintained by the Tenant with
respect to similar properties owned or leased by it. The policy of insurance
required to be maintained by the Tenant shall bear a standard first mortgagee
endorsement in favor of any holder of a mortgage created prior to the date of
this Lease Agreement. Within ten (10) days after commencement of this Lease
Agreement, Tenant shall deliver to the Landlord certificates of the insurers
evidencing all of the insurance which is required under this Section 18.

          (f)  Notwithstanding the above provisions of this Section 18, Tenant
may, at its option, self-insure the buildings and improvements on the Leased
Premises against damage or destruction by fire, windstorm and extended coverage
in lieu of obtaining insurance from an insurance company covering such buildings
and improvements on the Leased Premises against damage or destruction by fire,
windstorm and extended coverage. In the event that the Tenant does self-insure
such buildings and improvements on the Leased premises against damage or
destruction by fire, windstorm and extended coverage in lieu of obtaining
insurance from  

                                       13
<PAGE>
 
an insurance company covering such damage or destruction, notwithstanding
anything herein to the contrary, (i) Tenant shall have no obligation to obtain
such insurance from an insurance company covering the buildings and improvements
on the Leased Premises against damage or destruction by fire, windstorm and
extended coverage during the period that the Tenant is self-insuring such damage
or destruction, and (ii) in the event of damage to or destruction of any of the
buildings or improvements on the Leased Premises during the period that the
Tenant is self insuring such buildings and improvements and such damage or
destruction is due to a fire, windstorm or other casualty that would be
insurable under a standard fire, windstorm and extended coverage property
insurance policy in effect at the time of such damage or destruction, such
damage or destruction shall be repaired by, and at the expense of, the Tenant in
substantially the condition such damaged or destroyed building or improvement
was in immediately prior to such damage or destruction and the Tenant shall
begin such repair or restoration work as soon as possible after the date of such
casualty. If the Tenant does decide to self-insure the buildings and
improvements on the Leased Premises against damage or destruction by fire,
windstorm and extended coverage, the Tenant agrees to give the landlord written
notice of its decision no less than ten (10) days prior to the time the Tenant
will begin such self-insurance.

     19.  Waiver of Subrogation. Each party hereto waives any and every claim
          ---------------------                                              
that arises or may arise in its favor and against the 

                                       14
<PAGE>
 
other party hereto for any and all loss of, or damage to, any of the buildings,
improvements and/or its property located within or upon, or constituting a part
of, the Leased Premises to the extent such loss or damage is covered by fire and
extended coverage insurance. Said mutual waivers shall be in addition to, and
not in limitation or derogation of, any other waiver or release contained in
this Lease Agreement with respect to any loss of, or damage to buildings or
improvements located on the Leased Premises and/or property of the parties
hereto, inasmuch as the above mutual waivers will preclude the assignment of any
aforesaid claim by way of subrogation (or otherwise) to an insurance company (or
any other person), each party hereto hereby agreeing immediately to give to each
insurance company which has issued to it policies of fire and extended coverage
insurance, written notice of the terms of said mutual waivers, and to have said
insurance policies property endorsed, if necessary, to prevent the invalidation
of said insurance coverages by reason of said waivers.

     20.  Condemnation.
          ------------ 
          (a)  Complete Condemnation. If, after the execution and prior to the
               ---------------------                                          
termination of this Lease Agreement, the whole of the Leased Premises shall be
taken under the power of eminent domain by any public or private authority, then
this Lease Agreement and the term hereof shall cease and terminate as of the
date of such taking, with the right of Tenant, at its election, to continue to
occupy the Leased Premises, subject to the terms of this Lease Agreement, for
all or such part, as Tenant may determine, of the 

                                       15
<PAGE>
 
period between the date of such taking and the date when possession of the
Leased Premises shall be taken by the taking authority, and any unearned rent or
other charges, if any, paid in advance, shall be refunded to Tenant. If
required, Tenant shall procure from the applicable governmental authority, at
Tenant's expense, all necessary consents and authorizations to continue to
occupy the Leased Premises from and after the date of such taking.

          (b)  Partial Condemnation. If, after the execution and prior to the
               --------------------                                          
termination hereof, any public or private authority shall, under the power of
eminent domain, make a taking:

               (i)  Resulting in the reduction of the ground floor area of the
building on the Leased Premises by 20% or more, or

               (ii) Resulting in the reduction of the parking area on the Leased
Premises by 20% or more, then Tenant may, at its election, terminate this Lease
Agreement by giving Landlord notice of the exercise of its election within 60
days of the date of notice to Tenant of such taking (or purchase). In the event
of termination by Tenant under this Section, this Lease Agreement shall cease
and terminate as of the last day of the calendar month in which such notice of
exercise of its election to terminate has been given, and any unearned rent or
other charges, if any, paid in advance, shall be refunded to Tenant.

          (c)  Rent Adjustment. In the event that Tenant, having such right,
               ---------------                                              
shall not elect to terminate as aforesaid, then this Lease Agreement and the
term hereof shall continue in full force and effect, and Landlord shall, at its
expense, forthwith restore

                                       16
<PAGE>
 
what may remain of the Leased Premises, including any and all improvements made
theretofore, the parking areas and the Leased Premises, to substantially the
same condition they were in prior to such taking and a just proportion of the
rent provided in Section 4 hereof, and any other charges payable by Tenant
hereunder, according to the nature and extent of the injury to the Leased
Premises and Tenant's business shall be suspended or abated until what may
remain of the Leased Premises and the parking areas, shall be restored as
aforesaid, and thereafter a just proportion of the rent and any such other
charges according to the nature and extent of the taking and resulting injury to
the Leased Premises and Tenant's business shall be permanently abated for the
balance of the term of this Lease Agreement. In computing the amount of
proportionate rent reduction as herein provided, due consideration shall be
given to the value of the portion of the area so taken in condemnation with
relation to the remaining area insofar as the use thereof for Tenant's business
is concerned, and to the effect of such taking on Tenant's business, and the
amount of parking area and the value of what remains insofar as the use thereof
for Tenant's business is concerned.

          (d) Condemnation Award. All compensation awarded or paid for losses 
              ------------------                                             
or damages to the Leased Premises or losses or damages to the Landlord for loss
of its leasehold interest upon such a total or partial taking of the Leased
Premises under the power of eminent domain shall belong to and be the property
of the Landlord; provided however, that nothing contained herein shall be
construed

                                       17
<PAGE>
 
to preclude Tenant from (i) prosecuting and filing, and the Tenant shall be
entitled to prosecute and file, a claim directly against the condemning
authority in such condemnation proceedings for loss of or damage to Tenant's
business or suffered by Tenant due to loss of its leasehold interest,
depreciation to, damage to, or cost of removal of, or for value of stock, trade
fixtures, furniture and other personal property belonging to Tenant, as a result
of the partial or complete taking of the Leased Premises, and (ii) collecting

          (a) Restoration of Damaged Premises. In the event any of the buildings
              -------------------------------                                   
or improvements located on the Leased Premises are damaged or destroyed or
rendered partially untenantable by fire or other casualty, the Tenant shall as
soon as possible repair (but only from and to the extent of the insurance
proceeds released to Tenant from the joint account pursuant to Section 18(a)
hereof, except as otherwise specifically provided in Section 18(f) hereof) the
damaged or destroyed buildings and/or improvements located on the Leased
Premises to as nearly as possible the condition in which they were in

obligation to make any repairs to or restoration of the damaged buildings and
improvements on the Leased Premises the cost of which exceeds that portion of
such insurance proceeds made available to Tenant from such joint account to make
such repairs or restore such damaged buildings and improvements on

the Leased Premises, except as otherwise specifically provided in Section 18(f)
hereof.
          (b) Rent Abatement. During the period from the date of such casualty

until the buildings and improvements located on the Leased Premises are
repaired and restored, the rent payable by Tenant hereunder shall be abated
proportionately according to the floor area of the buildings and improvements
located on the Leased Premises which is usable by the Tenant after such
casualty. Such abatement shall continue for the period commencing with such
damage or destruction and ending with the completion of the work or repair. In

be completely abated from the date of the casualty.

          (c) Termination Option. Notwithstanding anything herein to the

Premises and Tenant's business shall be suspended or abated until what may
remain of the Leased Premises and the parking areas, shall be restored as
aforesaid, and thereafter a just proportion of the rent and any such other
charges according to the nature and extent of the taking and resulting injury to
the Leased Premises and Tenant's business shall be permanently abated for the
balance of the term of this Lease Agreement. In computing the amount of
proportionate rent reduction as herein provided, due consideration shall be

relation to the remaining area insofar as the use thereof for Tenant's business
is concerned, and to the effect of such taking on Tenant's business, and the
amount of parking area and the value of what remains insofar as the use thereof
for Tenant's business is concerned. So long as the loan from MetLife Capital
Financing Corporation ("MetLife") to Landlord which is secured by the Leased
Premises remains outstanding, any rent reduction pursuant to this Section 20.(c)
must be approved by MetLife.

Agreement shall be in any way prevented, interrupted or hindered by force

Agreement, Landlord shall remain liable as a guarantor hereunder in connection

successors or assigns in the event MetLife assumes title to the Leased Premises.

     9.   Paragraph 18.(c) of the Lease is hereby deleted in its entirety, and
the following new paragraph 18.(c) is substituted therefor:

          18.(c)    Any excess of money received from insurance remaining in the
joint account after the reconstruction or repair of such damaged buildings or
improvements on the Leased Premises shall, if the Tenant is not in default under
this Lease Agreement, be paid to Tenant.

     10.  Paragraph 18.(d) of the Lease is hereby deleted in its entirety, and
the following new paragraph 18.(d) is substituted therefor:

          18.(d)    If any mortgagee holding a mortgage on the Leased Premises
elects, in accordance with the terms of such mortgage, to require that all or
any part of the proceeds of such insurance paid as a result of damages to the
buildings and improvements located on the Leased Premises be paid to or retained
by the mortgagee, then such payment shall be made, but in such event, the

entire agreement between Landlord and Tenant and supersedes all prior agreements
and understandings between Landlord and Tenant relating to the subject matter of
the Lease and this instrument. There are not agreements, understandings,
restrictions, warranties, representations or inducements between the parties to
this instrument relating to the subject matter of the Lease or this instrument
other than those set forth in the Lease and this instrument.

to Lease Agreement in multiple original counterparts effective as of the date
set forth above.

MetLife Capital                                      Loan and Security Agreement

THIS LOAN AND SECURITY AGREEMENT entered into as of the 14th day of March, 1995,
by and between MetLife Capital Corporation, a Delaware corporation, whose
address is C-97550, 10900 NE 4/th/ Street, Suite 500, Bellevue, Washington 98009
("Lender") and International Environmental Corporation, a ______________, whose
address is 16 S. Pennsylvania, Oklahoma City, OK 73107 ("Borrower").

     WHEREAS, Lender has agreed to make a commercial loan or loans to Borrower;
and

     WHEREAS, as a condition to making the loans, and in order to secure the
repayment thereof, Lender has required Borrower to execute and deliver to Lender
this Loan and Security Agreement.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
accuracy of which are hereby acknowledged, Borrower and Lender agree as follows:

     1.   Creation of Security Interest.  As security for the due and punctual
          -----------------------------                                       
payment of any and all of the present and future obligations of the Borrower to
Lender, whether direct or contingent or joint or several, Borrower hereby
conveys, assigns and grants to Lender a continuing security interest in all of
Borrower's rights, title and interests in and to the equipment described in the
Supplemental Security Agreement from time to time ("Equipment") including all
present and future additions, attachments and accessories thereto, except
accounts and inventory, all substitutions therefor and replacements thereof and
all proceeds thereof, including all proceeds of insurance (such Equipment and
property hereinafter called "Collateral").

     2.   The Loans.  (a) Subject to the terms and conditions of this Loan and
          ---------                                                           
Security Agreement, Lender agrees to make a loan or loans to Borrower in
principal amount stated in the loan commitment letter issued by Lender to
Borrower (each such loan or loans shall be referred to as "the Loan Amount").

     (b)  The Loan Amount shall be repaid by Borrower as a term loan or term
          loans ("Term Loan"). The Term Loan shall be evidenced by a promissory
          note or notes in the form attached hereto as Exhibit "A" ("Term
          Note"0. The payment provisions of each Term Note shall be stated
          therein.

     (c)  If requested by Borrower, and in accordance with the terms and
          conditions of Section 3 hereof, Lender shall make interim fundings to
          Borrower of a Term Loan as partial advances of the Loan Amount
          ("Interim Loans"). The Interim Loans shall either be for the payment
          of the acquisition cost of any items of Equipment delivered and
          commitment to Borrower prior to the expiration date of
<PAGE>
 
          Lender's loan commitment to Borrower ("Commitment Expiration Date") or
          to fund progress payments to the vendor or manufacturer of the
          Equipment. If the making of progress payments was agreed to by Lender
          in its commitment or approval to make the loan or loans to Borrower.
          The Interim Loans shall be evidenced by promissory notes in the form
          attached hereto as Exhibit "B" ("Interim Note"). Interest on all
          Interim Loans shall be payable as provided therein. The principal
          amount due under the Interim Loans shall be due as provided in the
          Interim Notes, at which time, provided no Event of Default hereunder
          has occurred and is continuing or event which with the passing of time
          or giving of notice or both would become an Event of Default hereunder
          has occurred and is continuing, Lender shall consolidate all Interim
          Loans and convert them to a Term Loan evidenced by a Term Note or
          Notes. Whether or not a Term Loan is evidenced by one or more Term
          Notes shall be as agreed between Lender and Borrower, or in the
          absence of such an agreement, as decided by Lender, in the exercise of
          its reasonable business judgment.

     (d)  In the event that the amount loaned pursuant to the Interim Loans is
          less than the Loan Amount, subject to Borrower's compliance with the
          terms and conditions of this Loan and Security Agreement (including
          the satisfaction of the conditions of the borrowing set forth in
          Section 7 of this Loan and Security Agreement, including but not
          limited to providing Lender with a description of the items of
          Equipment), Lender shall disburse to Borrower the balance of the Loan
          Amount on the same date that the Interim Loans are converted into a
          term loan.

     3.   Method For Borrowing On Interim Loan.  Borrower shall give Lender at
          ------------------------------------                                
least five (5) business days written notice of a request for the disbursement of
an Interim Loan ("Request"), specifying the date on which the Interim Loan is to
be disbursed.  Such Request shall be in the form attached hereto as Exhibit "C."
Such Request shall be accompanied by an original copy of the invoice or invoices
to be paid from the Interim Loan.  Such Request shall constitute a
representation and warranty by the Borrower that (i) as of the date of the
Request no Event of Default or event which with the passing of time or the
giving of notice or both would constitute an Event of Default hereunder has
occurred and is continuing and (ii) in the event items of Equipment have been
delivered to the Borrower, Borrower has unconditionally accepted the Equipment
from the vendor thereof.  Subject to the conditions of this Loan and Security
Agreement, Lender shall disburse the Interim Loan to the invoicing party, or if
Borrower shall have paid the amount of such invoice, 

                                      -2-
<PAGE>
 
Lender shall reimburse Borrower, upon receipt of proof of payment from Borrower.

     4.   Cross-Collateral/Cross Default.  All Collateral shall secure the
          ------------------------------                                  
payment and performance of all of Borrower's liabilities and obligations to
Lender hereunder and under any of the loan documents relating hereto including,
but not limited to, all Interim Notes and all Term Notes (the Loan and Security
Agreement, the Interim Notes, the Term Notes, the Supplemental Security
Agreement(s) and all other loan documents may be referred to herein collectively
as the "Loan Documents").  Lender's security interest in the Collateral shall
not be terminated until and unless all of Borrower's obligations to Lender under
any of the Loan Documents are fully paid and performed.  The occurrence of an
Event of Default hereunder and an Event of Default hereunder shall be deemed to
be an event of default under any other of the Loan Documents

     5.   Representations and Warranties.  Borrower hereby represents and
          ------------------------------                                 
warrants as follows:

     (a)  Power and Authorization.  Borrower has the full power and (corporate)
          authority to execute, deliver and perform Borrower's obligations under
          the Loan Documents. The execution and delivery of the Loan Documents
          have been authorized by all requisite corporate (or partnership)
          action on the part of Borrower. The execution, delivery and
          performance of the Loan Documents have not constituted and will not
          constitute a breach, default or violation of or under Borrower's
          articles of incorporation, by-laws (partnership agreement), or any
          other agreement, indenture, contact, lease, law, order, decree,
          judgment, or injunction to which Borrower is a party or may be bound
          and have not resulted and will not result in the creation of any lien
          upon the Equipment pursuant to any agreement, indenture, lease,
          contract or other instrument to which Borrower is a party, except the
          lien created by this Loan and Security Agreement.

     (b)  Existence.  If Borrower is a corporation, Borrower (i) is duly
          incorporated, validly existing and in good standing under the laws of
          its state of incorporation, (ii) has all corporate powers and all
          governmental licenses, authorizations, consents and approvals required
          to carry on its business as now conducted, and (iii) is duly qualified
          to transact business as a foreign corporation in each jurisdiction
          where the Equipment will be located and in the jurisdiction where its
          principal place of business is located. If Borrower is a partnership,
          Borrower (i) has been duly formed as a (limited or general)
          partnership under the laws of the state of its organization, (ii) is
          comprised of the general partner(s) 

                                      -3-
<PAGE>
 
          listed on the Schedule of Partners attached to this Loan and Security
          Agreement, and (iii) is in good standing under the laws of the state
          of its formation.

     (c)  Binding Effect.  This Loan and Security Agreement constitutes the
          valid and binding agreement of the Borrower; the Interim Notes and the
          Term Note, when executed and delivered, will constitute the valid and
          binding obligations of the Borrower; and the Loan Documents are
          enforceable in accordance with the terms except as (i) the
          enforceability thereof may be limited by the bankruptcy laws, and (ii)
          rights of acceleration and the availability of equitable remedies may
          be limited by equitable principles of general applicability.

     (d)  Litigation.  Other than as disclosed in SEC filings, there is no
          action, suit or proceeding pending against, or to the knowledge of the
          Borrower, threatened against or affecting the Borrower, before any
          court or arbitrator or any governmental body, agency or official which
          has not been previously disclosed to the Lender in writing and in
          which there is a reasonable possibility of an adverse decision which
          could materially adversely affect the business, financial condition or
          results of operations of the Borrower or which would in any manner
          draw into question the validity of any of the Loan Documents.

     (e)  Filing of Tax Returns.  The Borrower has filed all tax returns
          required to have been filed and has paid all taxes shown to be due and
          payable on such returns, including interest and penalties, and all
          other taxes which are payable by it, to the extent the same have
          become due and payable. The Borrower knows of no proposed tax
          assessment against it and all tax liabilities of the Borrower are
          adequately provided for.

     (f)  Title.  The Borrower has or shall have at the time it executes the

          Agreement are true and accurate in all material respects and do not
          contain any untrue statement, or fail to contain any statement of a
          material fact necessary to make the statements contained herein or
          therein not misleading. There is no fact known to the Borrower that
          Borrower has not disclosed in writing which could materially and
          reasonably adversely affect the financial condition or operations of
          Borrower.

          releases or threatened releases of pollutants, contaminants, or
          hazardous or toxic materials or wastes into air, water, or land, or
          otherwise relating to the manufacture, processing, distribution, use,
          treatment, storage, disposal, transport, or handling of pollutants,

     (c)  No Liens.  Except for the security interest granted hereby or under
          any other agreement under which Lender is the secured party, whether
          as mortgagees, beneficiary or otherwise. Borrower shall keep the
          Collateral free and clear of any security interest, lien or
          encumbrance of any kind and Borrower shall not sell, assign (by
          operation of law or otherwise) exchange or otherwise dispose of any of
          the Collateral.

     (d)  Insurance.  Borrower shall procure and continuously maintain and pay
          for (a) all risk physical damage and property insurance covering loss

          value thereof naming Lender as loss payee and (b) bodily injury and
          property damage combined single limit liability insurance, all in such
          amounts and against such risks and hazards as are reasonably required
          by Lender, with insurance companies and pursuant to contracts or
          policies and with deductibles satisfactory to Lender. All contracts
          and policies shall include provisions for the protection of Lender
          notwithstanding any act or neglect of or breach or default by
          Borrower, shall provide for payment of insurance proceeds to Lender,
          shall provide that they may not be modified, terminated or canceled
          unless Lender is given at least thirty (30) days' advance written
          notice thereof, and shall provide that the coverage is "primary
          coverage" for the protection of Borrower or Lender notwithstanding any
          other coverage carried by Lender protecting against similar risks.
          Borrower shall promptly notify any appropriate insurer and Lender of
          each and every occurrence, which may become the basis of a claim or
          cause of action against the insured and provide Lender with all data
          pertinent to such occurrence. Borrower shall furnish Lender with
          certificates of such insurance or copies of policies upon request and
          shall furnish Lender with renewal certificates not less than thirty
          days prior to the renewal date. Proceeds of all insurance are payable
          first to Lender to the extent of its interest.

     (e)  Financing Statements.  At the request of Lender, Borrower will join
          Lender in executing one or more financing statements pursuant to the

          under applicable law to record or perfect its security interest in the
          Collateral, including continuation statements, in form satisfactory to
          Lender and will pay the cost of filing the same in all public offices
          wherever filing is deemed by the Lender to be necessary or desirable.
          Borrower hereby authorizes Lender, in such jurisdictions where such
          action is authorized by law, to effect any 

                                      -6-

          request of Lender, execute any additional financing statements or
          other similar documents necessary to perfect or maintain its security
          interest.

     (g)  Use of Equipment, Maintenance.  Borrower will cause the Equipment to
          be used in a careful and proper manner, will comply with and conform
          to all governmental laws, rules and regulation relating thereto, and
          will cause the Equipment to be operated in accordance with the
          manufacturer's or supplier's instructions or manuals and only by
          competent and duly qualified personnel. Borrower will cause the
          Equipment to be kept and maintained in good repair, condition and
          working order and will furnish all parts, replacements, mechanisms,
          devices and servicing required therefor so that the value, condition
          and operating efficiency thereof will at all times be maintained and
          preserved, normal wear and tear excepted. All such repairs, parts,
          mechanisms, devices and replacements shall immediately, without
          further act, become part of the Equipment and subject to the security
          interest created by this Loan and Security Agreement. Borrower will
          not make any improvement, change, addition or alteration to the
          Equipment if such improvement, change, addition or alteration will
          impair the originally intended function or use of the Equipment or
          impair the value of the Equipment as it existed immediately prior to
          such improvement, change, addition or alteration. Any part added to
          the Equipment in connection with any improvement, change or alteration
          shall immediately, without further act, become part of the Equipment
          and subject to the security interest created by this Loan and Security

          income) which may now or hereafter be imposed upon the ownership,
          leasing, possession, sale or use of the Collateral.

                                      -7-

     (j)  Performance by Lender.  If Borrower fails to perform any agreement or
          obligation contained herein, Lender may itself perform, or cause the
          performance of such agreement or obligation. Borrower will pay or
          reimburse Lender, on demand, for any and all fees, including
          reasonable attorneys' fees, costs and expenses of whatever kind or
          nature incurred by Lender in connection with (i) the creation,
          preservation and protection of Lender's security interest in the

          with respect to the Equipment, and (iv) this Loan and Security

          Collateral and Lender's interests therein, whether through judicial
          proceedings or otherwise, or in connection with defending or
          prosecuting any actions, suits or proceedings arising out of or
          related to the Loan and Security Agreement and the Loan Documents or
          in connection with any debt restructuring, loan workout negotiations
          or bankruptcy, or insolvency case or proceedings. All such amounts
          shall constitute obligations of Borrower secured by the Collateral in
          the event that Borrower fails to perform any of its agreements
          contained herein, Borrower will, on demand, reimburse Lender for all
          such expenditures, together with interest thereon from the date of
          such expenditure until fully reimbursed at the rate of two percent
          (2%) per month on the outstanding balance of such expenditures or the
          highest rate permitted by law, whichever is less.

     (k)  Power of Attorney.  Borrower hereby irrevocably appoints Lender
          Borrower's attorney-in-fact, with full authority in the place and
          stead of Borrower and in the name of Borrower or otherwise, from time
          to time in the Lender's discretion, to take any action and to execute
          any instrument which Lender may deem necessary or advisable to
          accomplish the purposes of this Loan and Security Agreement,

          Lender may deem necessary or desirable for the 

                                      -8-
<PAGE>
 
          collection of any of the Collateral or otherwise to enforce the rights
          of Lender with respect to any of the Collateral.

     (l)  No Duties.  The powers conferred on Lender hereunder are solely to

          condition of Borrower.

         ---------------------                                             
hereunder, Lender may, at its option, do any one or more of the following:

     (a)  Declare all obligations of Borrower to Lender to be immediately due
          and payable, whereupon all unpaid principal of and interest on said
          indebtedness and other amounts declared due and payable shall be and
          become immediately due and payable;

     (b)  Take possession of all or any of the Collateral and exclude therefrom
          Borrower and all others claiming under Borrower, and thereafter hold,
          store, use, operate, manage, maintain and control, make repairs,
          replacements, alterations, additions and improvements to and exercise
          all rights and powers of Borrower in respect to the Collateral or any
          part thereof. In the event Lender demands, or attempts to take
          possession of the Collateral in the exercise of any rights under this
          Loan and Security Agreement, Borrower promises and agrees to promptly
          turn over and deliver complete possession thereof to Lender;

     (c)  Require Borrower to assemble the Collateral, or any portion thereof,
          at a place designated by Lender and reasonably convenient to both
          parties, and promptly to deliver such Collateral to Lender, or an
          agent or representative designated by it;

     (d)  Sell, lease or otherwise dispose of the Collateral at public or
          private sale, without having the Collateral at the place of sale, and

          be a purchaser at any sale); and

     (e)  Exercise any remedies of a secured party under the Uniform Commercial
          Code as adopted in the state where the Collateral is located or any
          other applicable law.

               Except as to portions of the Collateral which are perishable or
          threaten to decline speedily in value or are of a type customarily
          sold on a recognized market, Lender shall give Borrower at least ten
          (10) days prior written notice of the time and place of any public or
          private sale of the Collateral or other intended disposition thereof
          to be made. Such notice may be 

                                      -12-

          mailed to Borrower at the address set forth in the first paragraph of
          this Loan and Security Agreement. Borrower hereby specifically agrees
          (to the extent that applicable law and public policy allows it to
          effectively do so) that any 0public or private sale held in accordance
          with the terms of this Loan and Security Agreement shall, for the
          purpose of the Uniform Commercial Code as adopted in the state where
          the Collateral is located and for all other purposes, be deemed to
          have been conducted in a commercially reasonable manner and in good
          faith.

               The proceeds of any sale under Section 9(d) shall be applied as
          follows:

          (i)       To the repayment of the costs and expenses of retaking,

                    Collateral (including legal expenses and attorneys' fees)
                    and the discharge of all assessments, encumbrances, charges
                    or liens, if any, on the Collateral prior to the lien hereof
                    (except any taxes, assessments, encumbrances, charges or
                    liens subject to which such sale shall have been made);

          (ii)      To the payment of the whole amount then due and unpaid of
                    the indebtedness of Borrower to Lender;

          Collateral pursuant to the terms hereof shall not operate to release
          Borrower until full payment of any deficiency has been made in cash.

and Security Agreement to contract in strict compliance with applicable usury
laws from time to time in effect. In furtherance thereof, the parties stipulate
and agree that none of the terms and provision contained in the Loan Documents
shall ever be construed to create a contract to pay for the use, 

                                      -13-

or damage is covered by insurance, except that while Borrower is not in default,
Lender agrees to apply toward payment of obligations of Borrower insurance
proceeds payable to Lender by reason of such damage, loss, theft, or
destruction.  In the event of any damage, loss, theft or destruction, partial or
complete, of any item of Equipment, Borrower shall promptly notify Lender in

outstanding principal balance due under the Interim Note or Term Note, as the
case may be, and all other amounts relating to that item of Equipment then due

terminated with respect to that item of Equipment only, and Lender will release
its interest in that item of Equipment.

Loan and Security Agreement or to the Collateral without Lender's prior written
consent.

     14.  Indemnification.  Borrower shall indemnify and hold harmless Lender
          ---------------

way relating to or arising out of this Loan and Security Agreement, the other
Loan Documents or the Collateral, except for any Claims resulting solely and
directly from Lender's gross negligence or willful misconduct.

     15.  Notices.  Whenever Borrower or Lender shall desire to give or serve
          -------

rights, options or elections hereunder, Lender shall not be deemed to have
waived any breach or default on the part of Borrower or to have released
Borrower from any of the obligations secured hereby, unless such waiver or
release is in writing and is signed by Lender.  In addition, the waiver by
Lender of any breach hereof for default in payment of an indebtedness secured
hereby shall not be deemed to constitute a waiver of any succeeding breach or
default.

     17.  Further Agreements.  From time to time, Borrower will execute such
          ------------------

preserve, and maintain the security interest granted hereby.

     18.  Binding upon Successors.  All agreements, covenants, conditions and
          -----------------------

          ---------                                                      
rescinded only by a writing expressly referring to this Loan and Security
Agreement, signed by both of the parties hereto.

     21.  Invalidity of Provisions.  Every provision of this Loan and Security
          ------------------------                                            
Agreement is intended to be severable.  In the event that any term or provision
hereof is declared by a court to be illegal or invalid for any reason
whatsoever, such illegality or invalidity shall not affect the balance of the
terms and provisions hereof, which terms and provisions shall remain binding and
enforceable, then to the extent possible all of the other provisions shall
nonetheless remain in full force and effect.

option, may provide financing for any Additions and Modifications to Leased
Property required by Lessee during the Lease term subject to the then prevailing
interest rates and the Lessee's credit standing. Lessee shall not move the
Leased Property from the location set forth in the Schedule(s) without Lessor's

LEASED PROPERTY DELINEATED ON THE SCHEDULE(S).

     6.   USE, OPERATION AND MAINTENANCE:  Lessee, at its expense will provide a
suitable place for the installation, operation and maintenance of all Leased
Property with all such facilities fully complying with the installation and
operational specifications outlined in pertinent 
Manufacturer's/Vendor's/Licensor's manuals. Lessee, without expense to Lessor,
will enter into and keep in force during the entire term of this Lease the best
standard Manufacturer's/Vendor's/Licensor's Maintenance Agreement in form and
substance approved by Lessor which will cause 
Manufacturer(s)/Vendor(s)/Licensor(s) to make all the necessary repairs,
adjustments, and replacements in accordance with such Agreement and entitle

changes available under the License or Maintenance Agreement. Lessee will

such as (but not limited to) using a version of software, other than the version
specified by the License to be used, making unauthorized modifications of the
Leased Property, failing to follow Manufacturer's/Vendor's/Licensor's operations
or maintenance instructions, or abusing, misusing or allowing negligent acts to
be caused by Lessee or those to whom Lessee gives access to the Leased Property.
Lessee will comply with all laws, rules, regulations or orders of any 
governmental agency with respect to the Leased Property or to the use, 
operation, maintenance or storage thereof.

     7.   RISK OF LOSS:  During the period the Leased Property is in transit or
in the possession of Lessee, Lessee shall assume all responsibility for loss or
damage and shall hold Lessor harmless against the same. In the event that,
during the term of the Lease or until the Leased Property shall have been
returned, if any of the Leased Property shall be confiscated, taken,
requisitioned. lost, stolen. destroyed or irreparably damaged for any cause
whatsoever (such occurrences hereinafter called "Casualty Occurrences"), Lessee
shall immediately and fully inform Lessor. In the case of Software, the erasure,
inoperability or other incapacity of the Software triggered by a preprogrammed
termination or limiting design or routine embedded in the Software shall also be
deemed a "Casualty Occurrence". Following a Casualty Occurrence, on the next
succeeding rent payment date, Lessee shall pay to Lessor, in addition to all
past due rentals and other amounts then late and outstanding, an amount equal to
the Casualty Value as determined by the attached Casualty Schedule as of the
date of the Casualty Occurrence. Upon the making of such payment by Lessee, the
rental for such Schedule(s) shall cease to accrue as of the date of such payment
and the term of the Lease as to such Schedule(s) shall

                                       4
<PAGE>
 
terminate. Insurance proceeds received by Lessor as the result of a Casualty
Occurrence with respect to any Schedule(s) shall be applied in reduction of
Lessee's obligation to pay the Casualty Value. The Casualty Value as of any rent
payment date (or as of any other date on which Casualty Value is payable) shall
be an amount equal to that percentage of the Purchase Price or License Fee as is
set forth in the Casualty Schedule attached hereto, opposite the number of such

Lessee as liquidated damages, and any remaining amounts shall be retained by
Lessor. Lessee shall remain liable to Lessor to the extent that the aggregate
amount of the sums referred to in clauses (i) through (iv) above shall exceed
the aggregate proceeds received by Lessor in connection with the disposition of

REPRESENTATION, OR WARRANTY SHALL BE BINDING UNLESS MADE A PART OF THIS LEASE BY

such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. To the extent
permitted by applicable law, Lessee hereby waives any provision of law which

[RE:]     REQUEST FOR PAYMENT TO VENDOR(S) IN ADVANCE OF LEASE COMMENCEMENT

Ladies/Gentlemen:

Reference is made to that Lease Agreement No. OL-09083 dated 4/26/96 by and
                                              --------       -------       
between INTERNATIONAL ENVIRONMENTAL CORPORATION as Lessee, and Amplicon, Inc.,
        ---------------------------------------                               
as Lessor, (the "Lease") and to Lease Schedule No. 01 and all related subsidiary
                                                   --                           
documents under the Lease (collectively, the "Agreement"). Notwithstanding
anything to the contrary contained therein, and to the limited extent hereof,
this Letter Agreement amends and supersedes the Agreement and is hereby
incorporated by reference herein.

Amplicon, Inc. (Lessor) has received a request from INTERNATIONAL ENVIRONMENTAL
                                                    ---------------------------
CORPORATION (Lessee) to advance funds to vendor(s) prior to Lessee's acceptance
- -----------                                                                    
of all items of Leased Property under the Agreement and as required to make
progress payments to such vendors. As adequate and valuable consideration for
Lessor advancing funds to vendor(s) on behalf of Lessee prior to Lessee's
acceptance of all of the subject Leased Property (hereinafter referred to as the
"Installation Period"), Lessee agrees to make the following terms and conditions
mutually binding under the Agreement:

     Lessee will pay to Lessor a daily pro-rata rental fee from the date each
     item of Leased property is delivered and installed through the
     "Commencement Date". The Commencement Date as further defined in Section 2.
     TERM of the Lease, shall be the date that the final item of Leased Property
     is installed and accepted by Lessee. If Lessor has advanced funds on items
     of Leased Property not yet delivered and accepted, the daily pro-rata
     rental fee will be calculated from the date of Lessors disbursement. The
     daily pro-rata rental fee will be calculated as follows: (0.018354 X (the
                                                               --------       
     cost of each item of installed Leased Property + amount of progress
     payments and deposits made)/30). This rental fee will be billed monthly.
     Lessor will not be required to fund on any items of Leased Property not
     installed and accepted by Lessee on or before 7/10/96 (the "Funding Cut-Off
                                                   -------                      
     Date"). If all of the Leased Property to be included in the above-
<PAGE>
 
     referenced Agreement is not accepted by the Lessee on or before the Funding
     Cut-Off Date, Lessor may, at its sole option, pursue one of the following
     alternatives: (a) Lessor may commence the Lease (using the Funding Cut-Off
     Date as the Commencement Date) based on the portion of the Leased Property
     which has been delivered and accepted by Lessee and paid for by Lessor as
     of the Funding Cut-Off Date, and demand that Lessee pay to Lessor an amount
     equal to that which Lessor has paid to vendor(s) on behalf of Lessee for
     items of Leased Property not yet installed and accepted, plus all pro-rata
     rental fees, taxes, late fees, and other charges which are due and owing;
     (b) Lessor may, at its sole and absolute discretion, extend the allowed
     Installation Period and establish a new Funding Cut-Off Date; or (c) Lessor
     may demand that Lessee pay to Lessor a total amount equal to that which
     Lessor has paid to vendor(s) on behalf of Lessee, plus all pro-rata rental
     fees, taxes, late fees, and other charges which are due and owing under the
     terms of the above-referenced Agreement. Should such a demand be made by
     Lessor, Lessee hereby unconditionally agrees to reimburse said funds to
     Lessor in full within ten business days of said demand, and Lessor, upon
     receipt of such payment in full, shall release Lessee from further payment
     obligations under the Lease. Lessee shall provide Lessor with updated
     financial information throughout the Installation Period as periodically
     requested by Lessor. Lessor shall reserve the right to terminate the
     Installation Period at any time in the event Lessor determines, at Lessor's
     sole discretion, that there has been a material adverse change in Lessee's
     financial condition, at which time Lessor would then have the right to
     elect either (a), (b) or (c) above. Irrespective of this Letter Agreement,
     all other terms and conditions including, without limitation, all payment
     obligations by Lessee under the Agreement shall remain absolute and
     unconditional without regard in any manner whatsoever to the pro-rata
     rental obligations and/or pro-rata rental period set forth herein. The
     acceptance by Lessee of all items of Leased Property is not a pre-condition
     to Lessee's performance of any of its obligations under the Agreement,
     including all rental and other payment obligations.

The Agreement is hereby duly amended to incorporate the foregoing revisions.
Please acknowledge your acceptance of the same by your authorized signature
below and return the original of this Letter Agreement to Amplicon, Inc. within
five days of the date hereof, retaining the enclosed copy for your records.

                                   EXHIBIT A


1.   Price and Price Adjustments. The cash purchase price of the Property is FOB
     ---------------------------                                                
point of shipment from within the United States as designated by Seller, and is
firm for thirty (30) days after the date of execution of this Agreement by
Seller. After such period Seller may, in its discretion, adjust the purchase
price of any unshipped Property to reflect cost increases and changes in market
conditions. Seller will give Buyer written notice of any such price adjustments.
Unless within seven (7) days after receiving such notice Buyer gives Seller
written notice of any objections to any such price adjustments, Buyer will be
deemed to have waived all such objections.

2.   Taxes. The cash purchase price of the Property is exclusive of any and all
     -----                                                                     
excise, sales, use or other taxes levied by any federal, state, county,
municipal or other governmental authorities all of which are for the account of
Buyer. Seller is authorized to make payment of any such taxes directly to the
taxing authority, and Buyer will reimburse Seller therefor. Such reimbursement
will be made on demand unless otherwise expressly agreed in writing. If Buyer
claims an exemption from such taxes, Buyer must provide evidence of such
exemption reasonably acceptable to Seller upon Seller's request.

3.   Freight Charges. Freight charges for shipment of the Property to Buyer,
     ---------------                                                        
including taxes on freight charges, if any, are for the account of Buyer and
will be billed freight collect. Freight charges for tooling and accessories will
be separately invoiced to Buyer and are payable net 30 days from the date of
invoice unless otherwise agreed in writing.

4.   Shipping Instructions. Seller will arrange for shipment and routing of the
     ---------------------                                                     
Property in accordance with the instructions (if any) set forth on the first
page hereof provided, however, if such instructions are unclear, incomplete or
impractical of implementation, or if no shipping instructions are set forth on
the first page hereof, Seller may, and is hereby authorized by Buyer to, arrange
for shipment and routing of the Property as Seller deems appropriate in its
exercise of due care and prudent judgment. In no event will Seller be liable for
any failure of the carrier to follow shipping instructions of either Buyer or
Seller. Charges will be billed freight collect.

5.   Shipment.  Seller may ship the Property in partial shipments. Seller will
     --------                                                                 
use reasonable commercial efforts to deliver the Property by the requested
delivery date set forth on the first page hereof, but will have no liability to
Buyer for late shipments. Monthly installments will not, however, commence until
all Property has been received by Buyer.

6.   Title, Risk of Loss and Insurance. Title to and all risk of loss of or
     ---------------------------------                                     
damage to the Property will pass from Seller to Buyer at 
<PAGE>
 
the shipping point. Unless otherwise expressly agreed in writing, the cost of
insurance on the Property while in transit will be borne by Buyer. Seller shall
arrange for such insurance sufficient to cover all costs and amounts of and
associated with the Property.

7.   Rigging. All costs of unloading the Property from the carrier upon arrival
     -------                                                                   
at the shipping destination and moving the Property to the installation site are
for the account of Buyer. Seller has no liability for and Buyer assumes all risk
of damage to or loss of the Property occurring in connection with such unloading
and moving, provided, however, that Seller shall be liable for damage or loss of
            --------  -------                                                   
the Property occurring during the shipping, loading, or installation of the
Property caused by any defect in or structural failure of the Property.

8.   Installation. Buyer will, at its expense, take all necessary steps to
     ------------                                                         
prepare the installation site for the installation of the Property. The cost of
installation is included in the purchase price of the Property. Installation
includes set up, start up and initial adjustment of operating performance.
Seller has the right to delegate installation to Amada Engineering and Service,
Inc. ("AESI"). Seller has no responsibility or liability for any failure of any
of the Property to meet any applicable codes or standards established by any
private organization or any federal, state, county, municipal or other
governmental authority; provided, however, that in the event of any such failure
to meet such codes or standards Seller or its delegate will, at the request of
Buyer, make such modifications to any of the Property as may be necessary to
bring such Property into compliance with any such codes or standards, unless
Seller in good faith determines that the cost to Seller of making any such
modifications is expected to exceed ten percent (10%) of the purchase price of
the Property or that the time required to effect such compliance including the
completion of any necessary inspections and the obtaining of any necessary
permits or approval(s) is expected to exceed one hundred eighty (180) days in
which case this will be considered a force majeure and resolved pursuant to
Section 11 of this Agreement. However, if Buyer so requests, Seller may, but
shall not be obligated to, proceed with such modifications at the sole expense
of Buyer, payment for which shall be made by Buyer in advance of Seller's
performance.

9.   Warranty and Limitation of Liability. (a) Except as may otherwise be set
     ------------------------------------                                    
forth in a written warranty of the Property executed by Seller, Seller makes no
warranty, express or implied, written or oral, and hereby expressly disclaims
all such warranties, including without limitation any warranties or
merchantability of fitness for a particular use or purpose. In no event shall
Seller be liable for any incidental, special or consequential damages (including
without limitation lost profits), and in no event shall Sellers liability exceed
the stated purchase price of the Property.

     (b)  Notwithstanding anything in this section 9 or in this Exhibit A
seemingly to the contrary, Seller warrants the proper operation of the Property
for two years from the date of completed installation. During such two year
period, the Seller will repair Property and pay for all costs of each repair
including but not limited to freight, parts and labor.

10.  Force Majeure. In the event that Seller or Buyer, or any of their suppliers
     -------------

God or of the public enemy, war, insurrection, riots, strikes, lockouts, labor
disputes, fires, floods, earthquakes, natural disasters, unavoidable casualty,
freight embargoes, shortages of labor or material, changes in governmental
policy, laws or regulations (including but not limited to money exchange or
transfer restrictions, impositions of quotas or limitations of shipments), or
any other cause or causes beyond control of Seller or its suppliers or
delegates, whether or not specified above, Seller and Buyer may extend the time
of performance of its obligations to such extent as may be necessary to enable
Seller and Buyer and their suppliers and delegates to complete performance with
the exercise of reasonable diligence after the cause or causes of delay have
been removed. In the event any such delay continues for a period of more than
six (6) months, either party may terminate its obligations hereunder by so
notifying the other party in writing.

11.  Termination. Upon the occurrence of an Event of Default, (as defined in
     -----------                                                            
Section B.6) after providing Buyer with written notice of such Event of Default
and a ten (10) business day opportunity to cure such default (Notice to Cure),
Seller will, in addition to the other rights set forth in this Agreement, have
the right to terminate this Agreement as to any unshipped Property with thirty
(30) day written notice of termination to Buyer.

12.  Late Charges. Any payment of Buyer not received by the ninth (9th) day

principal and interest that may be owing with respect to the Property at any
time without penalty of any kind.

14.  Indemnification. Buyer will defend, indemnify and hold Seller harmless from
     ---------------                                                            
and against any and all claims, liabilities, damages, costs and expenses
(including reasonable attorneys' fees) arising out of or in connection with any
use of the Property by Buyer (except where such claim is at least in part caused
by Seller's negligence or intentional act) or any breach of this Agreement by
Buyer.

in all accessions thereto and replacements or modifications thereof, as well as

use or operate the Property in a manner other than as intended by the
manufacturer, or in violation of any insurance policy covering the Property, or
remove or obliterate any marking affixed by Seller to the Property to give
notice of Seller's security interest therein or any identifying insignia, serial
number or lettering on the Property, or permit the Property to become so affixed
to realty as to become a fixture.

4.   Insurance. Buyer shall keep the Property insured against all risk of loss
     ---------

notice of the effective date of any alterations or cancellations of any
such policy. All such insurance policies shall otherwise be in form and
substance and with companies satisfactory to Seller. Buyer shall deliver such
insurance policies to Seller, or shall furnish to Seller such other evidence of
insurance as Seller may from time to time request. The proceeds of such
insurance shall be applied, at the option of Seller and Buyer, to (a)

     the Overdue Moneys first become payable and 4% per annum from and after
     such due date until payment of such moneys in fall to GE Capital. The
     Customer acknowledges that such interest is a genuine pre-estimate of GE
     Capital's cost of funding such overdue moneys and is not a penalty.

2.6  OPTION TO PURCHASE EQUIPMENT

     If the Customer is not in breach of any term of this Agreement and no event
     of default as specified in Clause 3.15 has occurred that it is continuing,
     the Customer may, at any time elect to purchase the Equipment specified in

     originally payable under the Agreement less any amounts (other than the
     deposit) paid or provided, whether by cash or other consideration, by or on
     behalf of the Customer under the Agreement and less -

     the Overdue Moneys first become payable and 4% per annum from and after
     such due date until payment of such moneys in full to GE Capital. The
     Customer acknowledges that such interest is a genuine pre-estimate of GE
     Capital's cost of funding such overdue moneys and is not a penalty.

2.6  OPTION TO PURCHASE HARDWARE

     If the Customer is not in breach of any term of this Agreement and no event
     of default as specified in Clause 3.15 has occurred that it is continuing,
     the Customer may, at any time elect to purchase the Hardware specified in

     Equipment to the Customer PROVIDED THAT unless and until the Customer makes
     such election, GE Capital shall retain full title and property to and in

                      Ratio of Earnings to Fixed Charges


For purposes of these computations, "earnings" represent net income before
income taxes plus fixed charges, less capitalized interest plus amortization of
interest capitalized in prior periods. "Fixed charges" consist of interest
expense, including amortization of debt issuance costs, capitalized interest and
the portion of rental expense which the Company believes is representative of
the interest component of rental expense.

     of the shareholders shall be given by first-class mail, postage prepaid,
     mailed at least ten days prior to the date of such meeting to each
     shareholder of record at his address as shown upon the books of this

<PAGE>
 
          TENTH. Every person who is or was a Director, officer or employee of
          -----
     the Association or of any other corporation which he served as a Director,
     officer or employee at the request of the Association as part of his
     regularly assigned duties may be indemnified by the Association in
     accordance with the provisions of this paragraph against all liability
     (including, without limitation, judgments, fines, penalties and
     settlements) and all reasonable expenses (including, without limitation,
     attorneys' fees and investigative expenses) that may be incurred or paid by
     him in connection with any claim, action, suit or proceeding, whether
     civil, criminal or administrative (all referred to hereafter in this
     paragraphs as "Claims") or in connection with any appeal relating thereto
     in which he may become involved as a party or otherwise or with which he
     may be threatened by reason of his being or having been a Director, officer
     or employee of the Association or such other corporation, or by reason of
     any action taken or omitted by him in his capacity as such Director,
     officer or employee, whether or not he continues to be such at the time
     such liability or expenses are incurred, provided that nothing contained in
     this paragraph shall be construed to permit indemnification of any such
     person who is adjudged guilty of, or liable for, willful misconduct, gross
     neglect of duty or criminal acts, unless, at the time such indemnification
     is sought, such indemnification in such instance is permissible under
     applicable law and regulations, including published rulings of the
     Comptroller of the Currency or other appropriate supervisory or regulatory
     authority, and provided further that there shall be no indemnification of
     directors, officers, or employees against expenses, penalties, or other
     payments incurred in an administrative proceeding or action instituted by
     an appropriate regulatory agency which proceeding or action results in a
     final order assessing civil money penalties or requiring affirmative action
     by an individual or individuals in the form of payments to the Association.
     Every person who may be indemnified under the provisions of this paragraph
     and who has been wholly successful on the merits with respect to any Claim
     shall be entitled to indemnification as of right. Except as provided in the
     preceding sentence, any indemnification under this paragraph shall be at
     the sole discretion of the Board of Directors and shall be made only if the
     Board of Directors or the Executive Committee acting by a quorum consisting
     of

                                      -7-
<PAGE>
 
     Directors who are not parties to such Claim shall find or if independent
     legal counsel (who may be the regular counsel of the Association) selected
     by the Board of Directors or Executive Committee whether or not a
     disinterested quorum exists shall render their opinion that in view of all
     of the circumstances then surrounding the Claim, such indemnification is
     equitable and in the best interests of the Association.  Among the
     circumstances to be taken into consideration in arriving at such a finding
     or opinion is the existence or non-existence of a contract of insurance or
     indemnity under which the Association would be wholly or partially
     reimbursed for such indemnification, but the existence or non-existence of
     such insurance is not the sole circumstance to be considered nor shall it
     be wholly determinative of whether such indemnification shall be made.  In
     addition to such finding or opinion, no indemnification under this
     paragraph shall be made unless the Board of Directors or the Executive
     Committee acting by a quorum consisting of Directors who are not parties to
     such Claim shall find or if independent legal counsel (who may be the
     regular counsel of the Association) selected by the Board of Directors or
     Executive Committee whether or not a disinterested quorum exists shall
     render their opinion that the Director, officer or employee acted in good
     faith in what he reasonably believed to be the best interests of the
     Association or such other corporation and further in the case of any
     criminal action or proceeding, that the Director, officer or employee
     reasonably believed his conduct to be lawful.  Determination of any Claim
     by judgment adverse to a Director, officer or employee by settlement with
     or without Court approval or conviction upon a plea of guilty or of
     nolocontendere or its equivalent shall not create a presumption that a
     --------------                                                        
     Director, officer or employee failed to meet the standards of conduct set
     forth in this paragraph.  Expenses incurred with respect to any Claim may
     be advanced by the Association prior to the final disposition thereof upon
     receipt of an undertaking satisfactory to the Association by or on behalf
     of the recipient to repay such amount unless it is ultimately determined
     that he is entitled to indemnification under this paragraph.  The rights of
     indemnification provided in this paragraph shall be in addition to any
     rights to which any Director, officer or employee may otherwise be entitled
     by contract or as a matter of law.

     Every person who shall act as a Director, officer or employee of this
     Association shall be conclusively presumed to be doing so in reliance upon
     the right of indemnification provided for in this paragraph.

          ELEVENTH. These Articles of Association may be amended at any regular
          --------
     or special meeting of the shareholders by the affirmative vote of the
     holders of a majority of the stock of this Association, unless the vote of
     the holders of a greater amount of stock is required by law, and in that
     case by the vote of the holders of such greater amount.

     may designate a person to be the Secretary of the meetings of shareholders.
     In the absence of a presiding officer, as designated in these By-Laws, the
     Board of Directors may designate a person to act as the presiding officer.
     In the event the Board of Directors fails to designate a person to preside
     at a meeting of shareholders and a Secretary of such meeting, the
     shareholders present or represented shall elect a person to preside and a
     person to serve as Secretary of the meeting.

          The Secretary of the meetings of shareholders shall cause the returns
     made by the judges and election and other proceedings to be recorded in the
     minute book of the Bank.  The presiding officer shall notify the directors-
     elect of their election and to meet forthwith for the organization of the
     new board.

     and the Secretary designated for the meeting.

     SECTION 1.04.  JUDGES OF ELECTION.  The Board of Directors may appoint as

     conduct the same, and who shall, after the election has been held, notify,
     in writing over their signatures, the secretary of the shareholders'
     meeting of the result thereof and the names of the Directors elected;
     provided, however, that upon failure for any reason of any judge or judges
     of election, so appointed by the directors, to serve, the presiding officer
     of the meeting shall appoint other shareholders or their proxies to fill
     the vacancies.  The judges of election at the request of the chairman of

     meeting, and shall notify, in writing over their signatures, the secretary
     of the Board of Directors of the result thereof.

     SECTION 1.05.  PROXIES.  In all elections of Directors, each shareholder of
     ----------------------                                                     
     record, who is qualified to vote under the provisions of Federal Law, shall
     have the right to vote the number of shares of record in his name for as
     many persons as there are Directors to be elected, or to cumulate such
     shares as provided by Federal Law.  In deciding all other questions at
     meetings of shareholders, each shareholder shall be entitled to one vote on
     each share of stock of record in his name.  Shareholders may vote by proxy
     duly authorized in writing.  All proxies used at the annual meeting shall
     be secured for that meeting only, or any adjournment thereof, and shall be

     of receipt thereof.  No officer or employee of this Bank may act as proxy.

     SECTION 1.06.  QUORUM.  Holders of record of a majority of the shares of

     the capital stock of the Bank, eligible to be voted, present either in
     person or by proxy, shall constitute a quorum for the transaction of
     business at any meeting of shareholders, but shareholders present at any
     meeting and constituting less than a quorum may, without further notice,
     adjourn the meeting from time to time until a quorum is obtained.  A

                                  ----------

                                   DIRECTORS
                                   ---------

     SECTION 2.01.  MANAGEMENT OF THE BANK.  The business of the Bank shall be
     -------------------------------------                                    
     managed by the Board of Directors.  Each director of the Bank shall be the
     beneficial owner of a substantial number of shares of BANC ONE CORPORATION
     and shall be employed either in the position of Chief Executive Officer or
     active leadership within his or her business, professional or community
     interest which shall be located within the geographic area in which the
     Bank operates, or as an executive officer of the Bank.  A director shall
     not be eligible for nomination and re-election as a director of the Bank if
     such person's executive or leadership position within his or her business,
     professional or community interests which qualifies such person as a
     director of Bank terminates.  The age of 70 is the mandatory retirement age
     as a director of the Bank.  When a person's eligibility as director of the
     Bank terminates, whether because of change in share ownership, position,
     residency or age, within 30 days after such termination, such person shall
     submit his resignation as a director to be effective at the pleasure of the
     Board provided, however, that in no event shall such person be nominated or
     elected as a director.  Provided, however, following a person's retirement
     or resignation as a director because of the age limitations herein set
     forth with respect to election or re-election as a director, such person
     may, in special or unusual circumstances, and at the discretion of the
     Board, be elected by the directors as a Director Emeritus of the Bank for a
     limited period of time.  A Director Emeritus shall have the right to
     participate in board meetings but shall be without the power to vote and
     shall be subject to re-election by the Board at its organizational meeting
     following the Bank's annual meeting of shareholders.

     SECTION 2.02.  QUALIFICATIONS.  Each director shall have the qualification
     -----------------------------                                             
     prescribed by law.  No person elected a director may exercise any of the
     powers of his office until he has taken the oath of such office.

                                     -13-

     SECTION 2.03.  TERM OF OFFICE/VACANCIES.  A director shall hold office
     ----------------------------------------                              
     until the annual meeting for the year in which his term expires and until
     his successor shall be elected and shall qualify, subject, however, to his
     prior death, resignation, or removal from office. Whenever any vacancy
     shall occur among the directors, the remaining directors shall constitute
     the directors of the Bank until such vacancy is filled by the remaining
     directors, and any director so appointed shall hold office for the
     unexpired term of his or her successor.  Notwithstanding the foregoing,
     each director shall hold office and serve at the pleasure of the Board.

     SECTION 2.04.  ORGANIZATION MEETING.  The directors elected by the share-
     -----------------------------------                                      
     holders shall meet for organization of the new board at the time fixed by
     the presiding officer of the annual meeting.  If at the time fixed for such
     meeting there is no quorum present, the Directors in attendance may adjourn
     from time to time until a quorum is obtained.  A majority of the number of
     Directors elected by the shareholders shall constitute a quorum for the
     transaction of business.

     SECTION 2.05.  REGULAR MEETINGS.  The regular meetings of the Board of
     -------------------------------                                       
     Directors shall be held on the third Monday of each calendar month
     excluding March and July, which meeting will be held at 4:00 p.m.  When any
     regular meeting of the Board falls on a holiday, the meeting shall be held
     on such other day as the Board may previously designate or should the Board
     fail to so designate, on such day as the Chairman of the Board of President
     may fix.  Whenever a quorum is not present, the directors in attendance
     shall adjourn the meeting to a time not later than the date fixed by the
     Bylaws for the next succeeding regular meeting of the Board.

     SECTION 2.06.  SPECIAL MEETINGS.  Special meetings of the Board of
     -------------------------------                                   
     Directors shall be held at the call of the Chairman of the Board or
     President, or at the request of two or more Directors.  Any special meeting
     may be held at such place in Franklin County, Ohio, and at such time as may
     be fixed in the call.  Written or oral notice shall be given to each
     Director not later than the day next preceding the day on which special
     meeting is to be held, which notice may be waived in writing.

                                     -14-
<PAGE>
 
     The presence of a Director at any meeting of the Board shall be deemed a
     waiver of notice thereof by him.  Whenever a quorum is not present the
     Directors in attendance shall adjourn the special meeting from day to day
     until a quorum is obtained.

     SECTION 2.07.  QUORUM.  A majority of the Directors shall constitute a
     ---------------------                                                 
     quorum at any meeting, except when otherwise provided by law; but a lesser
     number may adjourn any meeting, from time-to-time, and the meeting may be
     held, as adjourned, without further notice.  When, however, less than a
     quorum as herein defined, but at least one-third and not less than two of
     the authorized number of Directors are present at a meeting of the
     Directors, business of the Bank may be transacted and matters before the
     Board approved or disapproved by the unanimous vote of the Directors
     present.

     SECTION 2.08.  COMPENSATION.  Each member of the Board of Directors shall
     ---------------------------                                              
     receive such fees for, and transportation expenses incident to, attendance
     at Board and Board Committee Meetings and such fees for service as a
     Director irrespective of meeting attendance as from time to time are fixed
     by resolution of the Board; provided, however, that payment hereunder shall
     not be made to a Director for meetings attended and/or Board service which
     are not for the Bank's sole benefit and which are concurrent and
     duplicative with meetings attended or board service for an affiliate of the
     Bank for which the Director receives payment; and provided further, that
     payment hereunder shall not be made in the case of any Director in the
     regular employment of the Bank or of one of its affiliates.

     SECTION 2.09.  EXECUTIVE COMMITTEE.  There shall be a standing committee of
     ----------------------------------                                         
     the Board of Directors known as the Executive Committee which shall possess
     and exercise, when the Board is not in session, all powers of the Board
     that may lawfully be delegated.  The Executive Committee shall also
     exercise the powers of the Board of Directors in accordance with the
     Provisions of the "Employees Retirement Plan" and the "Agreement and
     Declaration of Trust" as the same now

                                     -15-
<PAGE>
 
     exist or may be amended hereafter.  The Executive Committee shall consist
     of not fewer than four board members, including the Chairman of the Board
     and President of the Bank, one of whom, as hereinafter required by these
     By-laws, shall be the Chief Executive Officer.  The other members of the
     Committee shall be appointed by the Chairman of the Board or by the
     President, with the approval of the Board and shall continue as members of
     the Executive Committee until their successors are appointed, provided,
     however, that any member of the Executive Committee may be removed by the
     Board upon a majority vote thereof at any regular or special meeting of the
     Board.  The Chairman or President shall fill any vacancy in the Committee
     by the appointment of another Director, subject to the approval of the
     Board of Directors.  The regular meetings of the Executive Committee shall
     be held on a regular basis as scheduled by the Board of Directors.  Special
     meetings of the Executive Committee shall be held at the call of the
     Chairman or President or any two members thereof at such time or times as
     may be designated.  In the event of the absence of any member or members of
     the Committee, the presiding member may appoint a member or members of the
     Board to fill the place or places of such absent member or members to serve
     during such absence.  Not fewer than three members of the Committee must be
     present at any meeting of the Executive Committee to constitute a quorum,
     provided, however that with regard to any matters on which the Executive
     Committee shall vote, a majority of the Committee members present at the
     meeting at which a vote is to be taken shall not be officers of the Bank
     and, provided further, that if, at any meeting at which the Chairman of the
     Board and President are both present, Committee members who are not
     officers are not in the majority, then the Chairman of the Board or
     President, which ever of such officers is not also the Chief Executive
     Officer, shall not be eligible to vote at such meeting and shall not be
     recognized for purposes of determining if a quorum is present at such
     meeting.  When neither the Chairman of the Board nor President are present,
     the Committee shall appoint a presiding officer.  The Executive Committee
     shall keep a record of its proceedings and report its proceedings and the
     action taken by it to the Board of Directors.

     which shall be, at least once in each calendar year, to review, develop and
     recommend policies and programs related to the Bank's Community
     Reinvestment Act Compliance and regulatory compliance with all existing

     review of current Bank policies with regard to Community Reinvestment Act
     and regulatory compliance in writing to the Board, with recommendations, if
     any, which may be necessary to correct any unsatisfactory conditions.  Such

     and Banc One Corporation and may engage outside Community Reinvestment Act
     experts, as approved by the Board, to review, develop and recommend
     policies and programs as herein required.  The Community Reinvestment Act
     and regulatory compliance policies and procedures established and the
     recommendations made shall be consistent with, and shall supplement, the
     Community Reinvestment Act and regulatory compliance programs, policies and
     procedures of Banc One Corporation and Banc One Ohio Corporation.  The
     Community Reinvestment Act and Compliance Policy Committee shall consist of
     not fewer than four board members, one of whom shall be the Chief Executive

     The term "Expiration Date" means 5:00 p.m., New York City time, on
________________, 1998, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term will mean the latest date and time to

bond power from the registered holder.  Capitalized terms used but not defined
herein have the respective meanings set forth in the Prospectus.

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to ClimaChem, Inc. (the "Company"), the principal
amount of Old Notes indicated above.

     Subject to and effective upon the acceptance for exchange of the principal
amount of Old Notes tendered in accordance with this Letter of Transmittal, the
undersigned sells, assigns and transfers to, or upon the order of, the Company
all right, title and interest in and to the Old Notes tendered hereby.  The
undersigned hereby irrevocably constitutes and appoints the Exchange Agent its
agent and attorney-in-fact (with full knowledge that the Exchange Agent also
acts as the agent of the Company) with respect to the tendered Old Notes with
the full power of substitution to (a) present such Old Notes and all evidences
of transfer and authenticity to, or transfer ownership of, such Old Notes on the
account books maintained by the Book-Entry Transfer Facility to, or upon, the
order of, the Company, (b) deliver certificates for such Old Notes to the
Company and deliver all accompanying evidences of transfer and authenticity to,
or upon the order of, the Company and (c) present such Old Notes for transfer on
the books of the Company and receive all benefits and otherwise exercise all
rights of beneficial ownership of such Old Notes, all in accordance with the
terms of the Exchange Offer.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Old Notes
tendered hereby and that the Company will acquire good, valid and unencumbered
title thereto, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claims, when the same are acquired
by the Company. The undersigned hereby further represents that any New Notes
acquired in exchange for Old Notes tendered hereby will have been acquired in
the ordinary course of business of the person receiving such New Notes, whether
or not such person is the undersigned, that neither the undersigned nor any
other such person has any arrangement or understanding with any person to
participate in the distribution of such New Notes and that neither the
undersigned nor any such other person is an "affiliate," as defined in Rule 405
under the Securities Act of 1933, as amended, of the Company.  In addition, the
undersigned and any such person acknowledge that (a) any person participating in
the Exchange Offer for the purpose of distributing the New Notes must, in the
absence of an exemption therefrom, comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale of the New Notes and cannot rely on the position of the Staff of the
Securities and Exchange Commission  enunciated in no-action letters and (b)
failure to comply with such requirements in such instance could result in the
undersigned or such person incurring liability under the Securities Act for
which the undersigned or such person is not indemnified by the Company.  The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Exchange Agent or the Company to be necessary or desirable to
complete the assignment, transfer and purchase of the Old Notes tendered hereby.
If the undersigned is not a broker-dealer, the undersigned represents that it is
not engaged in and does not intend to engage in, a distribution of New Notes. If
the undersigned is a broker-dealer that will receive New Notes for its own
account in exchange for Old Notes that were acquired as a result of market-
making activities or other trading activities, it acknowledges that it will
deliver a Prospectus in connection with any resale of such New Notes, however,
by so acknowledging and by delivering a Prospectus, the undersigned will not be
deemed to admit that it is an "underwriter" the meaning of the Securities Act.
Unless otherwise notified in accordance with the instructions set forth in Box 4
under "Broker-Dealer Status," the Company will assume that the undersigned is
not a Participating Broker-Dealer.

     For purposes of the Exchange Offer, the Company will be deemed to have
accepted validly tendered Old Notes when, as and if the Company has given oral
or written notice thereof to the Exchange Agent.

     If any Old Notes tendered herewith are not accepted for exchange pursuant
to the Exchange Offer for any reason, certificates for any such unaccepted Old
Notes will be returned promptly after the Expiration Date, without expense, to
the undersigned at the address shown below or to a different address as may be
indicated herein in Box 3 under "Special Delivery Instructions."

     All authority conferred or agreed to be conferred by this Letter of
Transmittal will survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal will be binding upon the undersigned's heirs, personal
representative, successors and assigns.

     The undersigned understands that tenders of Old Notes pursuant to the
procedures described under the caption "The Exchange Offer--Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and the Company upon the terms and
subject  to the conditions of the Exchange Offer, subject only to withdrawal of
such  tenders on the terms set forth in the Prospectus under the caption "The
Exchange Offer--Withdrawal of Tenders."

     Unless otherwise indicated in Box 2 under "Special Registration
Instructions," please issue the certificates (or electronic transfers)
representing the New Notes issued in exchange for the Old Notes accepted for
exchange and any certificates (or electronic transfers) for Old Notes not
tendered or not exchanged, in the name(s) of the undersigned.  Similarly, unless

completed, please issue the certificates representing the New Notes issued in
exchange for the Old Notes accepted for exchange in the name(s) of, and return
any certificates for Old Notes not tendered or not exchanged to, the person(s)
so indicated.  The undersigned understands that the Company has no obligation
pursuant to the "Special Registration Instructions" and "Special Delivery
Instructions" to transfer any Old Notes from the name of the registered
Holder(s) thereof if the Company does not accept for exchange any of the Old
Notes so tendered.

     Holders who wish to tender their Old Notes and (a) whose Old Notes are not

Transmittal or any other documents required hereby to the Exchange Agent prior
to the Expiration Date, may tender their Old Notes according to the guaranteed
delivery procedures set forth in the Prospectus under the caption "The Exchange
Offer--Guaranteed Delivery Procedures." See Instruction 2 regarding the

                    FORMING PART OF THE TERMS AND CONDITION
                             OF THE EXCHANGE OFFER

     1.  DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES FOR OLD NOTES
OR BOOK-ENTRY CONFIRMATIONS.  Certificates representing the tendered Old Notes
(or a confirmation of book-entry transfer into the Exchange Agent's account with
the Book-Entry Transfer Facility for tendered Old Notes transferred
electronically), as well as a properly completed and duly executed copy of this
Letter of Transmittal (or facsimile thereof), a Substitute Form W-9 (or
facsimile thereof) and any other documents required by this Letter of
Transmittal must be received by the Exchange Agent at its address set forth
herein prior to the Expiration Date. The method of delivery of certificates for
Old Notes and all other required documents is at the election and sole risk of
the tendering holder and delivery will be deemed made only when actually
received by the Exchange Agent.  If delivery is by mail, registered mail with
return receipt requested, properly insured, is recommended.  As an alternative
to delivery by mail, the holder may wish to use an overnight or hand delivery
service.  In all cases, sufficient time should be allowed to assure timely
delivery.  Neither the Company nor the Exchange Agent is under an obligation to
notify any tendering holder of the Company's acceptance of tendered Old Notes
prior to the completion of the Exchange Offer.

                                      -7-

     2.   GUARANTEED DELIVERY PROCEDURES.  Holders who wish to tender their Old
Notes but whose Old Notes are not immediately available and who cannot deliver
their certificates for Old Notes (or comply with the procedures for book-entry
transfer prior to the Expiration Date), the Letter of Transmittal and any other
documents required by the Letter of Transmittal to the Exchange Agent prior to
the Expiration Date must tender their Old Notes according to the guaranteed
delivery procedures set forth below.  Pursuant to such procedures:

     (a)  such tender must be made by or through a firm which is a member of a
          registered national securities exchange or of the National Association
          of Securities Dealers, Inc., or a commercial bank or trust company
          having an office or correspondent in the United States (an "Eligible
          Institution");

     (b)  prior to the Expiration Date, the Exchange Agent must have received
          from the holder and the Eligible Institution a properly completed and
          duly executed Notice of Guaranteed Delivery (by facsimile
          transmission, mail, or hand delivery) setting forth the name and
          address of the holder, the certificate number or numbers of the
          tendered Old Notes, and the principal amount of tendered Old Notes and
          stating that the tender is being made thereby and guaranteeing that,
          within five New York Stock Exchange trading days after the Expiration
          Date, the Letter of Transmittal (or facsimile thereof), together with
          the tendered Old Notes (or a confirmation of book-entry transfer into
          the Exchange Agent's account with the Book-Entry Transfer Facility for
          Old Notes transferred electronically) and any other required documents
          will be deposited by the Eligible Institution with the Exchange Agent;
          and

     (c)  such properly completed and executed Letter of Transmittal and
          certificates representing the tendered Old Notes in proper form for
          transfer (or a confirmation of book-entry transfer into the Exchange
          Agent's account with the Book-Entry Transfer Facility for Old Notes
          transferred electronically) must be received by the Exchange Agent
          within five New York Stock Exchange trading days after the Expiration
          Date.

     Any Holder who wishes to tender Old Notes pursuant to the guaranteed
delivery procedures described above must ensure that the Exchange Agent receives
the Notice of Guaranteed Delivery relating to such Old Notes prior to the
Expiration Date.  Failure to complete the guaranteed delivery procedures
outlined above will not, of itself, affect the validity or effect a revocation
of any Letter of Transmittal form properly completed and executed by a Holder
who attempted to use the guaranteed delivery person.

     3.  TENDER BY HOLDER.  Only a holder of Old Notes may tender such Old Notes
in the Exchange Offer.  Any beneficial owner of Old Notes who is not the
registered holder and who wishes to tender should arrange with such holder to
execute and deliver this Letter of Transmittal on such owner's behalf or must,
prior to completing and executing this Letter of Transmittal and delivering such
Old Notes, either make appropriate arrangements to register ownership of the Old
Notes in such owner's name or obtain a properly completed bond power from the
registered holder.

     4.  PARTIAL TENDERS.  Tenders of Old Notes will be accepted only in
integral multiples of $1,000 in principal amount.  If less than the entire
principal amount of Old Notes is tendered, the tendering holder should fill in
the principal amount tendered in the column labeled "Principal Amount Tendered"
of the box entitled "Description of Old Notes" (Box 1) above.  The entire
principal amount of Old Notes delivered to the Exchange Agent will be deemed to
have been tendered unless otherwise indicated.  If the entire principal amount
of Old Notes is not tendered, Old Notes for the principal amount of Old Notes
not tendered and New Notes exchanged for any Old Notes tendered will be sent to
the Holder at his or her registered address (or transferred to the account of
the Book-Entry Facility designated above), unless a different address (or
account) is provided in the appropriate box on this Letter of Transmittal, as
soon as practicable following the Expiration Date.

                                      -8-

     5.  SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
MEDALLION GUARANTEE OF SIGNATURE.  If this Letter of  Transmittal is signed by
the registered holder(s) of the Old Notes tendered herewith, the signatures must
correspond with the name(s) as written on the face of the tendered Old Notes
without alteration, enlargement, or any change whatsoever.  If this Letter of
Transmittal is signed by a participant in the Book-Entry Transfer Facility, the
signature must correspond with the name as  it appears on the security position
listing as the owner of the Old Notes.

     If any of the tendered Old Notes are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal.  If any tendered
Old Notes are held in different names on several Old Notes, it will be necessary
to complete, sign, and submit as many separate copies of the Letter of
Transmittal documents as there are names in which tendered Old Notes are held.

     If this Letter of Transmittal is signed by the registered holder or
Authorized Holder, and New Notes are to be issued and any untendered or
unaccepted principal amount of Old Notes are to be reissued or returned to the
registered holder or Authorized Holder, then, the registered holder or
Authorized Holder need not and should not endorse any tendered Old Notes nor
provide a separate bond power.  In any other case (including if this Letter of
Transmittal is not signed by the Authorized Holder), the registered holder or
Authorized Holder must either properly endorse the Old Notes tendered or
transmit a properly completed separate bond power with this Letter of
Transmittal (in either case, executed exactly as the name(s) of the registered
holder(s) appear(s) on such Old Notes, and, with respect to a participant in the
Book-Entry Transfer Facility whose name appears on a security position listing
as the owner of Old Notes, exactly as the name(s) of the participant(s)
appear(s) on such security position listings), with the signature(s) on the
endorsement or bond power guaranteed by an Eligible Institution unless such
certificates or bond powers are signed by an Eligible Institution.

     If this Letter of Transmittal or any Old Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations, or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing and evidence satisfactory to the Company
of their authority to so act must be submitted with this Letter of Transmittal.

     No medallion signature guarantee is required if (i) this Letter of
Transmittal is signed by the registered holder(s) of the Old Notes tendered
herewith (or by a participant in the Book-Entry Transfer Facility whose name
appears on a security position listing as the owner of the Tendered Notes) and
the issuance of New Notes (and any Old Notes not tendered or not accepted) are
to be issued directly to such registered holder(s) (or, if signed by a
participant in the Book-Entry Transfer Facility, any New Notes or Old Notes not
tendered or not accepted are to be deposited to such participant's account at
such Book-Entry Transfer Facility) and neither the "Special Delivery
Instructions" (Box 3) nor the "Special Registration Instructions" (Box 2) has
been completed, or (ii) such Old Notes are tendered for the account of an
Eligible Institution.  In all other cases, all signatures on this Letter of
Transmittal must be guaranteed by an Eligible Institution.

     6.  SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS.  Tendering holders
should indicate, in the applicable box, the name and address (or account at the
Book-Entry Transfer Facility) in which the New Notes and/or substitute Old Notes
for principal amounts not tendered or not accepted for exchange are to be sent
(or deposited), if different from the name and address or account of the person
signing this Letter of Transmittal.  In the case of issuance in a different
name, the employer identification number or social security number of the person
named must also be indicated and the indicated and the tendering holders should
complete the applicable box.

     If no such instructions are given, the New Notes (and any Old Notes not
tendered or not accepted) will be issued in the name of and sent to the
Authorized Holder of the Old Notes or deposited at such Authorized Holders'
account at the Book-Entry Transfer Facility.

     7.  TRANSFER TAXES.  The Company will pay all transfer taxes, if any,
applicable to the sale and transfer of Old Notes to it or its order pursuant to
the Exchange Offer.  If, however, a

                                      -9-
<PAGE>
 
transfer tax is imposed for any reason other than the transfer and sale of Old
Notes to the Company or its order  pursuant to the Exchange Offer, then the
amount of any such transfer taxes (whether imposed on the registered holder or
on any other person) will be payable by the tendering holder. If satisfactory
evidence of payment of such taxes or exemption from taxes therefrom is not
submitted with this Letter of Transmittal, the amount of transfer taxes will be
billed directly to such tendering holder.

     Except as provided in this Instruction 7, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes listed in this Letter of
Transmittal.

     8.  TAX IDENTIFICATION NUMBER.  Federal income tax law required that a
holder of any Old Notes which are accepted for exchange must provide the Company
(as payor) with its correct taxpayer identification number ("TIN"), which, in
the case of a holder who is an individual, is his or her social security number.
If the Company is not provided with the correct TIN, the Holder may be subject
to a $50 penalty imposed by Internal Revenue Service. (If withholding results in
an over-payment of taxes, a refund may be obtained.) Certain holders (including,
among other, all corporations and certain foreign individuals) are not subject
to these backup withholding and reporting requirements.  See the enclosed
"Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9" for additional instructions.

     To prevent backup withholding, each tendering holder must provide such
holder's correct TIN by completing the Substitute Form W-9 set forth herein,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN), and that (a) the holder has not been notified by the Internal Revenue
Service that such holder is subject to backup withholding as a result of
failure to report a interest or dividends or (b) the Internal Revenue Service
has notified the holder that such holder is no longer subject to backup
withholding. If the Old Notes are registered in more than one name or are not in
the name of the actual owner, see the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for information on which
TIN to report.

     The Company reserves the right in its sole discretion to take whatever
steps are necessary to comply with the Company's obligation regarding backup
withholding.

     9.  VALIDITY OF TENDERS.  All questions as to the validity, form,
eligibility (including time of receipt), and acceptance of tendered Old Notes
will be determined by the Company, in its sole discretion, which determination
will be final and binding.  The Company reserves the right to reject any and all
Old Notes not validly tendered or any Old Notes, the Company's acceptance of
which would, in the opinion of the Company or its counsel, be unlawful.  The
Company also reserves the right to waive any conditions of the Exchange Offer or
defects or irregularities in tenders of Old Notes as to any ineligibility of any
holder who seeks to tender Old Notes in the Exchange Offer.  The interpretation
of the terms and conditions of the Exchange Offer (includes this Letter of
Transmittal and the instructions hereto) by the Company shall be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Old Notes must be cured within such time as the
Company shall determine. The Company will use reasonable efforts to give
notification of defects or irregularities with respect to tenders of Old Notes,
but shall not incur any liability for failure to give such notification.

     10.  WAIVER OF CONDITIONS.  The Company reserves the absolute right to
amend, waive, or modify specified conditions in the Exchange Offer in the case
of any tendered Old Notes.

     11.  NO CONDITIONAL TENDER.  No alternative, conditional, irregular, or
contingent tender of Old Notes on transmittal of this Letter of Transmittal will
be accepted.

     12.  MUTILATED, LOST, STOLEN, OR DESTROYED OLD NOTES.  Any tendering holder
whose Old Notes have been mutilated, lost, stolen, or destroyed should contact
the Exchange Agent at the address indicated above for further instruction.

                                      -10-

     13.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions and requests
for assistance and requests for additional copies of the Prospectus may be
directed to the Exchange Agent at the first address specified on page one of
this Agreement. Holders may also contact their broker, dealer, commercial bank,
trust company, or other nominee for assistance concerning the Exchange Offer.

     14.  ACCEPTANCE OF TENDERED OLD NOTES AND ISSUANCE OF NEW NOTES; RETURN OF
OLD NOTES.  Subject to the terms and conditions of the Exchange Offer, the
Company will accept for exchange all validly tendered Old Notes as soon as
practicable after the Expiration Date and will issue New Notes therefor as soon
as practicable thereafter.  For purposes of the Exchange Offer, the Company
shall be deemed to have accepted tendered Old Notes when, as and if the Company
has given written and oral notice thereof to the Exchange Agent.  If any
tendered Old Notes are not exchanged pursuant to the Exchange Offer for any
reason, such unexchanged Old Notes will be returned, without expense, to the
undersigned at the address shown above (or credited to the undersigned's account
at the Book-Entry Transfer Facility designated above) or at a different address
as may be indicated under "Special Delivery Instructions."

     15.  WITHDRAWAL.  Tenders may be withdrawn only pursuit to the limited
withdrawal rights set forth in the Prospectus under the caption "The Exchange
Offer--Withdrawal of Tenders."

Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT TO
THE PAYOR. IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS, ALSO
SIGN AND DATE THE FORM.

Certain payments other than interest, dividends, and patronage dividends that
are not subject to information reporting are also not subject to backup
withholding.  For details, see the regulations under sections 6041, 6041 A(a),
6045, and 6050A. PRIVACY ACT NOTICE--Section 6109 requires most recipients of
dividend, interest, or other payments to give taxpayer identification numbers to
payors who must report the payments to the IRS.  The IRS uses the number for
identification purposes.  Payors must be given the numbers whether or not
recipients are required to file tax returns.  Payors must generally withhold 20%
of taxable interest, dividend, and certain other payments to a payee who does
not furnish a taxpayer identification number to a payor.  Certain penalties may
also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER--If you fail
to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless your failure is due to reasonable
cause and not to willful neglect.

(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
underpayment attributable to that failure unless there is clear and convincing
evidence to the contrary.

(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.

(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Certifications or affirmations
may subject you to criminal penalties including fines and/or imprisonment.
FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.

by written notice to Exchange Agent.

7.   Application of the New Notes.  The New Notes and any other property (the
     ----------------------------                                            
"Property") to be deposited with, or received by Exchange Agent from the Company
pursuant to this Agreement constitute a special, segregated account, held solely
for the benefit of the Company and Holders tendering Old Notes.  The Property
shall not be commingled with the securities, money, assets or property of
Exchange Agent or any other person, firm or corporation.  Exchange Agent hereby
waives any and all rights of lien (including banker's lien), attachment or set-
off whatsoever, if any, against the Property, whether such rights arise by
reason of statutory or common law, by contract or otherwise except to the extent
set forth in the Indenture with respect to the Old Notes and the New Notes.

8.   Reports.  On each business day after receipt of the first Letter of
     -------                                                            
Transmittal, and up to and including the Expiration Date, Exchange Agent shall
advise by telephone, not later than 5:00 p.m., Eastern Standard Time, Company
Counsel, and such other persons as they may direct, of the principal amount of
the Old Notes which have been duly tendered on such day, stating (a) the
principal amount of the Old Notes tendered pursuant to the Depository Trust
Company's Automated Tender Offer Program, as described in the Prospectus, (b)
the principal amount of the Old Notes tendered about which Exchange Agent has
questions concerning the validity and (c) the aggregate principal amount of the
Old Notes tendered and not withdrawn through the time of such telephone call.
Promptly thereafter (by the next day), Exchange Agent will confirm such advice
to each of the above persons in writing, to be transmitted by telefacsimile,
overnight courier or other special form of delivery.  Exchange Agent will also
inform them, upon request made from time to time, of such other information as
such persons may request.

9.   Discrepancies.  Exchange Agent shall endeavor to reconcile any
     -------------                                                 
discrepancies between the amount of the Old Notes claimed to be owned by a
surrendering holder of the Old Notes and the amount of the Old Notes indicated
on the books of the Company as of the record date (as defined in the section of
the Prospectus captioned "The Exchange Offer").  If, based upon reliable
documentation, Exchange Agent determines that the Old Notes with respect to
which such discrepancy exists are valid Old Notes, then Exchange Agent shall
deliver the New Notes provided for herein to the holder surrendering such Old
Notes.  In the case of any question about whether the Old Notes are valid Old
Notes, Exchange Agent will be entitled to received instructions from the
Company.

10.  Old Notes and Other Names.  If an New Note is to be registered in a name
     -------------------------                                               
other than that of the record holder of a surrendered Old Note, conditions to
the issuance thereof are that (a) the Old Note so surrendered shall be properly
endorsed and otherwise in proper form for transfer and that the person
requesting such exchange shall pay to Exchange Agent any transfer or other taxes
required by reason of the registration of such New Note in any name other than
that of the holder of the Old Notes surrendered, or otherwise required, or shall
establish to Exchange Agent's satisfaction that such tax has been paid or is not
payable, and (b) the record holder deliver such other documents and instruments
as Company counsel or Exchange Agent shall require.  If the Letter of
Transmittal is signed by a person other than the registered holder of the Old
Note tendered in proper form for transfer or the New Note is to be issued (or
any untendered principal amount of the Old Note is to be reissued) to a person
other than the registered holder of the tendered Old Note, the registered holder
must either properly endorse the Old Note tendered or transmit a properly
completed separate bond power with the Letter of Transmittal, with the signature
on the endorsement or bond power guaranteed by an Eligible Institution (as
defined in the Letter of Transmittal).  In addition, such registered holder
and/or such other person will deliver such other documents and instruments as
Company Counsel or Exchange Agent shall require, in which case the New Note will
be mailed to such assignee or transferee at the address so required.

11.  Partial Tenders.  If, pursuant to the Exchange Offer, a Holder tenders less
     ---------------                                                            
than all of the principal amount of Old Notes submitted to Exchange Agent,
Exchange Agent will, promptly after the Expiration Date, return, or cause the
registrar to return, an Old Note for the principal amount not being tendered to,
or in accordance with the instructions of, such Holder who has made a partial
tender of Old Notes deposited with Exchange Agent.

12.  Withdrawals.  If a tendering Holder withdraws tendered Old Notes pursuant
     -----------                                                              
to the terms of the Exchange Offer, Exchange Agent will, as promptly as
practicable after proper notification of such withdrawal, return such Old Notes
to, or in accordance with the instructions of, such Holder, and such Old Notes
will no longer be considered properly tendered.  All questions as to the form
and validity of notices of withdrawal, including timeliness of receipt, shall be
determined by the Company, in its sole discretion, which determination will be
final and binding.

13.  Rejection of Tenders.  If, pursuant to the Exchange Offer, the Company does
     --------------------                                                       
not accept for Exchange all of the Old Notes tendered by a Holder of Old Notes,
Exchange Agent will, promptly

                                      -4-

accepted to, or in accordance with the instructions of, such holder of Old
Notes, together with a letter or notice furnished by the Company, in form
satisfactory to Exchange Agent, explaining why the tendered Old Notes are being
returned.

14.  Lost Certificates.  If a Holder of the Old Notes reports the loss or
     -----------------                                                   
destruction of any Old Note, Exchange Agent will obtain from such Holder an
affidavit and any other representation that Exchange Agent may require with
reference to the circumstances of such loss or destruction. The Company or
Exchange Agent may require, as a condition precedent to delivering a New Note to
such Holder, that such Holder deliver to the Company a bond or other security in
such reasonable sum as the Company may direct as indemnity against any claim
that may be made against Exchange Agent or the Company with respect to the Old
Note alleged to have been lost or destroyed.

15.  Cancellation of Exchanged Old Notes.  Exchange Agent is authorized and
     -----------------------------------                                   
directed to cancel, in accordance with the procedures set forth in the
Indenture, all Old Notes received by Exchange Agent upon delivering the New
Notes to tendering holders of the Old Notes as provided herein.

the Old Notes.  Upon request by an person, Exchange Agent shall furnish to such
person copies of the Prospectus, any supplements to the Prospectus, the Letter

thereunder in connection with the Exchange Offer and will file with the Internal
Revenue Service all reports and other information required to be filed with the

Agent has questions with respect to any such information, it will so notify, and
request direction from, the Company.
