                  (d)  Notwithstanding anything to the contrary set forth in this Section 2.6, if at any time until payment in full of the Notes, the interest rate payable on any Notes exceeds the highest rate of interest permissible under any law which a court of competent jurisdiction shall, in a final determination, deem applicable hereto (the "Maximum Lawful Rate"), then in such event and so long as the Maximum Lawful Rate would be so exceeded, the rate of interest payable on such Notes shall be equal to the Maximum Lawful Rate; provided, however, that if at any time thereafter the interest rate payable on such Notes is less than the Maximum Lawful Rate, ClimaChem shall continue to pay interest thereunder at the Maximum Lawful Rate until such time as the total interest received by the Purchasers is equal to the total interest which they would have received had the interest rate on such Notes been (but for the operation of this paragraph) the applicable interest rate payable since the Initial Closing Date.  Thereafter, the interest rate payable on such Notes shall be the applicable interest rate pursuant to clauses (a) through (c) above unless and until such rate again exceeds the Maximum Lawful Rate, in which event this paragraph shall again apply.  In no event shall the total interest received by any Purchaser for any Notes pursuant to the terms hereof exceed the amount which it could lawfully have received for such Notes had the interest due hereunder for such Notes been calculated for the full term thereof at the Maximum Lawful Rate.  In the event the Maximum Lawful Rate is calculated pursuant to this paragraph, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made.  In the event that a court of competent jurisdiction, notwithstanding the provisions of this Section 2.6(d), shall make a final determination that a Purchaser has received interest hereunder or under any of the Loan Documents in excess of the Maximum Lawful Rate, such Purchaser shall, to the extent permitted by applicable law, promptly apply such excess first to any Cash Interest due or accrued and not yet paid under the Notes, then to any Additional Interest due or accrued and not yet paid under the Notes, then to the outstanding principal of the Notes, then to other unpaid Obligations and thereafter shall refund any excess to ClimaChem or as a court of competent jurisdiction may otherwise order.

           2.7     Receipt
of Payments.  ClimaChem shall make each payment under the Notes not later than 2:00 P.M. (New York City time) on the day when due in lawful money of the United States of America in immediately available funds to each Purchaser's respective depository bank in the United States as designated by such Purchaser from time to time for deposit in such Purchaser's depositary account.  For purposes only of computing interest under the Notes, all payments shall be applied by each Purchaser to the Notes on the day payment has been credited by such Purchaser's depository bank to such Purchaser's account in immediately available funds.

           2.8     Application
of Payments.  ClimaChem irrevocably waives the right to direct the application of any and all payments at any time or times hereafter received by any Purchaser from or on behalf of ClimaChem pursuant to the terms of this Agreement, and ClimaChem irrevocably agrees that each

19

Purchaser shall have the continuing exclusive right to apply any and all such payments against the then due and payable Obligations and in repayment of the Notes as the Required Holders may deem advisable.  In the absence of a specific determination by the Required Holders with respect thereto, the same shall be applied in the following order:  (i) then due and payable fees and expenses; (ii) then due and payable or accrued Cash Interest payments on the Notes;  (iii) then due and payable or accrued Additional Interest payments on the Notes; (iv) then outstanding principal of the Notes; and (v) then other unpaid Obligations.

           2.9     Sharing
of Payments.  If any holder of the Notes or a portion thereof shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Notes held by it in excess of its ratable share of payments on account of the Notes, held by all holders thereof, such holder shall forthwith purchase from each other holder of Notes, as applicable, such participations in the Note held by it as shall be necessary to cause such purchasing holder to share the excess payment ratably with each other holder of Notes; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing holder, such purchase shall be rescinded and such holder shall repay to the purchasing holder the purchase price to the extent of such recovery together with an amount equal to such holder's ratable share (according to the proportion of (i) the amount of such holder's required repayment to (ii) the total amount so recovered from the purchasing holder) of any interest or other amount paid or payable by the purchasing holder in respect of the total amount so recovered.  ClimaChem agrees that any holder so purchasing a participation from another holder pursuant to this Section 2.9 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such holder were the direct creditor of ClimaChem in the amount of such participation.  ClimaChem further agrees to make all payments on the Notes to all holders thereof on a pro rata basis, based on the principal amount of the Notes held by each.

           2.10  Access.
Each Purchaser and any of its officers, employees and/or agents shall have the right, exercisable as frequently as it reasonably determines to be appropriate, during normal business hours, to visit and inspect the properties and facilities of ClimaChem and its Subsidiaries and to inspect, audit and make extracts from all of  ClimaChem and its Subsidiaries' records, files, corporate books and books of account and to discuss the affairs, finances and accounts of ClimaChem and its Subsidiaries with the principal officers of the respective Person, all at such reasonable times, upon reasonable notice and as often as such Purchaser may reasonably request.  ClimaChem shall deliver any document or instrument reasonably necessary for such Purchaser, as it may request, to obtain records from any service bureau maintaining records for ClimaChem and its Subsidiaries.  ClimaChem shall instruct its and its Subsidiaries' banking and other financial institutions to make available to such Purchaser such information and records as it may reasonably request.

           2.11  Taxes.  Any and all payments by ClimaChem hereunder or under the Notes shall be made, in accordance with this Section 2.11, free and clear of and without deduction for any and all present or future

20

taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding taxes imposed on or measured by the net income of the respective Purchaser, by the jurisdiction under the laws of which such Purchaser is organized or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes").  If ClimaChem shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under the Notes to any Purchaser, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.11) such Purchaser receives an amount equal to the sum it would have received had no such deductions been made, (ii) ClimaChem shall make such deductions, and (iii) ClimaChem shall pay the full amount deducted to the relevant taxing or other authority in accordance with applicable law.

                  (b) 
In addition, ClimaChem agrees to pay any present or future stamp or documentary taxes or any other sales, transfer, exercise, mortgage recording or property taxes, charges or similar levies that arise from any payment made hereunder or under the Notes or from the execution, sale, transfer, delivery or registration of, or otherwise with respect to, any of the Transaction Documents (hereinafter referred to as "Other Taxes").

                   (c)  ClimaChem shall indemnify each Purchaser for the full amount of Taxes or Other Taxes (including without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.11) paid by such Purchaser and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted.  This indemnification shall be made within 30 days from the date such Purchaser makes written demand
therefor. 

                  (d)  Within 30 days after the date of any payment of Taxes, ClimaChem shall furnish to each Purchaser the original or a certified copy of a receipt evidencing payment thereof.

                   (e)  Without prejudice to the survival of any other agreement of any Credit Party hereunder, the agreements and obligations of ClimaChem contained in this Section 2.11 shall survive the payment in full of the Notes.

            2.12  Original
Issue Discount.  The Credit Parties and the Purchasers hereby acknowledge and agree that the Warrants are part of an investment unit within the meaning of Section 1273(c)(2) of the IRC, which includes the Notes being purchased by the Purchasers.  Notwithstanding anything to the contrary contained herein, the Credit Parties and the Purchasers hereby further acknowledge and agree that for United States federal, state and local income tax purposes the "issue price" of the Warrants and the Notes under Section 1273(b) of the IRC shall equal $_____ and $______, respectively.  The Credit Parties and the Purchasers agree to use the foregoing issue prices for all income tax purposes with respect to this transaction.

3.     CREATION OF SECURITY INTEREST.

           3.1  Grant
of Security Interest.  Each Credit Party grants to the Collateral Agent, for the benefit of itself and the Purchasers, a continuing security interest in all of its right, title, and interest in all currently existing and hereafter acquired or arising Collateral in order to secure prompt repayment of any and all of the Obligations in accordance with the terms and conditions of the Loan Documents and in order to secure prompt performance by the Credit Parties of each of their covenants and duties under the Loan Documents.  The Collateral Agent's Liens in and to the Collateral shall attach to all Collateral without further act on the part of the Collateral Agent, or the Credit Parties.  Anything contained in this Agreement or any other Loan Document to the contrary notwithstanding, except for Permitted Dispositions and as provided in Sections 6.2(c), 6.2(d) and 8, the Credit Parties have no authority, express or implied, to dispose of any item or portion of the Collateral.

           3.2     Cash
Collateral Accounts. The Collateral Agent has established a deposit account (the "Cash Collateral Account") at Harris Bank, designated as "Guggenheim ClimaChem Collateral Account".  The Collateral Agent may establish one or more other deposit accounts and one or more Securities Accounts with such depositaries and securities intermediaries as it in its sole discretion shall determine.  Each such account shall be in the name of the Collateral Agent (but may also have words referring to ClimaChem and the account's purpose).  ClimaChem agrees that each such account shall be under the sole dominion and control of the Collateral Agent.  The Collateral Agent shall be the entitlement holder with respect to each such Securities Account and the only Person authorized to give entitlement orders with respect thereto.  Without limiting the foregoing, funds on deposit in any Cash Collateral Account may be invested in Cash Equivalents, and only Cash Equivalents, at the direction of the Collateral Agent and the Purchasers, on a pro rata basis, shall be entitled to any income from any such investment; provided, however, that the Collateral Agent shall not have any responsibility for, or bear any risk of loss of, any such investment.  Neither ClimaChem nor any other Credit Party or Person claiming on behalf of or through ClimaChem or any other Credit Party shall have any right to demand payment of any of the funds held in any Cash Collateral Account at any time prior to the earlier of (i) the date on which all Obligations are irrevocably paid in full and (ii) the Cash Collateral Release Date.  Upon request by ClimaChem at any time after the Cash Collateral Release Date, so long as no Default or Event of Default is then continuing, the Collateral Agent shall, at ClimaChem's expense, remit or release all amounts in the Cash Collateral Account less (i) any amount representing income earned on the funds on deposit in the Cash Collateral Accounts and (ii) all fees payable pursuant to Section 6.1(n) hereof.  The Required Holders may, at any time, in their sole discretion, apply any and all amounts in any Cash Collateral Account to any Cash Interest payable on the Notes or to the other Obligations if not paid when due, after applicable grace periods.

             3.3  Collection
of Accounts, and General Intangibles. At any time after the occurrence and during the continuation of an Event of Default, the Collateral Agent or the Collateral Agent's designee may (a) notify Account Debtors of the Credit Parties that the Accounts, chattel paper, or General Intangibles have

22

been assigned to the Collateral Agent or that the Collateral Agent has a security interest therein, or (b) collect the Accounts, chattel paper, or General Intangibles directly and include the collection costs and expenses as part of the Obligations.  Subject to the rights of the parties that have a first Lien on the Accounts, chattel paper or General Intangibles of any of the Credit Parties, each Credit Party agrees that it will hold in trust for the Purchasers, as the Purchasers' trustee, any Collections that it receives and immediately will deliver said Collections to the Collateral Agent in their original form as received by the applicable Credit Party.

            3.4    Delivery
of Additional Documentation Required.  At any time upon the request of the Collateral Agent, the Credit Parties shall execute and deliver to the Collateral Agent, any and all financing statements, original financing statements in lieu of continuation statements, fixture filings, security agreements, pledges, assignments, endorsements of certificates of title, and all other documents (the "Additional Documents") that the Collateral Agent may request in its reasonable discretion, in form and substance satisfactory to the Collateral Agent, to perfect and continue perfected or better perfect the Collateral Agent's Liens in the Collateral (whether now owned or hereafter arising or acquired) and in order to fully consummate all of the transactions contemplated hereby and under the other Loan Documents.  To the maximum extent permitted by applicable law, each Credit Party authorizes the Collateral Agent to execute any such Additional Documents in the applicable Credit
Party's name and authorizes the Collateral Agent to file such executed Additional Documents in any appropriate filing office.  The Collateral Agent shall forward to such Credit Party a copy of such Additional Documents before filing.  In addition, on such periodic basis as the Collateral Agent shall require in its reasonable discretion, the Credit Parties shall (a) provide the Collateral Agent with a report of all new patentable, copyrightable, or trademarkable materials acquired or generated by the Credit Parties during a prior period, (b) cause all patents, copyrights, and trademarks acquired or generated by the Credit Parties that are not already the subject of a registration with the appropriate filing office (or an application therefor diligently prosecuted) to be registered with such appropriate filing office in a manner sufficient to impart constructive notice of the Credit Parties' ownership thereof, and (c) cause to be prepared, executed, and delivered to the Collateral Agent supplemental schedules to the applicable Loan Documents to identify such patents, copyrights, and trademarks as being subject to the security interests created thereunder.

           3.5  Power
of Attorney.  Each Credit Party hereby irrevocably makes, constitutes, and appoints the Collateral Agent (and any of the Collateral
Agent's officers, employees, or agents designated by the Collateral Agent) as such Credit
Party's true and lawful attorney, with power to (a) if such Credit Party refuses to, or fails timely to execute and deliver any of the documents described in Section 3.3, sign the name of such Credit Party on any of the documents described in Section 3.3, (b) at any time that an Event of Default has occurred and is continuing, sign such Credit
Party's name on any invoice or bill of lading relating to the Collateral, drafts against Account Debtors, or notices to Account Debtors, (c) send requests for verification of Accounts, (d) endorse such Credit
Party's name on any Collection item that may come into

23

the any Purchaser's possession, (e) at any time that an Event of Default has occurred and is continuing, make, settle, and adjust all claims under such Credit
Party's policies of liability insurance and other insurance covering any Collateral and make all determinations and decisions with respect to such policies of insurance, and (f) at any time that an Event of Default has occurred and is continuing, settle and adjust disputes an claims respecting the Accounts, chattel paper, or General Intangibles directly with Account Debtors, for amounts and upon terms that the Collateral Agent determines to be reasonable, and the Collateral Agent may cause to be executed and delivered any documents and releases that the Collateral Agent determines to be necessary.  The appointment of the Collateral Agent as each Credit
Party's attorney, and each and every one of its rights and powers, being coupled with an interest, is irrevocable until all of the Obligations have been fully and finally repaid and performed.

           3.6  Right
to Inspect.  The Collateral Agent and each Purchaser (through any of their respective officers, employees, or agents) shall have the right, from time to time hereafter upon reasonable notice to ClimaChem or the applicable Credit Party to inspect the books and records and to check, test, and appraise the Collateral in order to verify the Credit Parties' financial condition or the amount, quality, value, condition of, or any other matter relating to, the Collateral.

           3.7  Code
and Other Remedies. Subject to the rights under the Foothill Loan Agreement, during the continuance of an Event of Default, the Collateral Agent may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the Code or any other applicable law.  Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Credit Party or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of the Collateral Agent or any Purchaser or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk.  The Collateral Agent shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Credit Party, which right or equity is hereby waived and released.  Each Credit Party further agrees, at the Collateral Agent's request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at such Credit
Party's premises or elsewhere.

24

The Collateral Agent shall apply the net proceeds of any action taken by it pursuant to this Section 3.7, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent and the Purchasers hereunder, including reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in accordance with the terms of this Agreement, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, need the Collateral Agent account for the surplus, if any, to any Credit Party.  To the extent permitted by applicable law, each Credit Party waives all claims, damages and demands it may acquire against the Collateral Agent or any Purchaser arising out of the exercise by them of any rights hereunder, unless such claim is the result of the gross negligence or willful misconduct of the Collateral Agent.  If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition.

           3.8     Deficiency. 
Each Credit Party shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the reasonable fees and disbursements of any attorneys employed by the Collateral Agent or any Purchaser to collect such deficiency.

           3.9     Lien
Priority and Subordination.  The Collateral Agent shall have a first priority Lien on the First Priority Collateral, free and clear of all Liens and encumbrances and subject only to Permitted Liens, except that any Liens described in clause (b) of the definition of Permitted Liens shall be junior to the Lien of Collateral Agent in the First Priority Collateral.  The Collateral Agent shall have a Lien on all Second Priority Collateral, free and clear of all Liens and encumbrances, subject only to Permitted Liens.

4.     PURCHASERS' REPRESENTATIONS AND WARRANTIES

           Each Purchaser, severally and not jointly, makes the following representations and warranties to ClimaChem, each and all of which shall survive the execution and delivery of this Agreement and the Initial Closing and any Additional Closings hereunder:

           4.1  Investment
Intention.  Such Purchaser is purchasing the Securities for its own account, for investment purposes and not with a view to the distribution thereof.  Such Purchaser will not, directly or indirectly, offer, transfer, sell, assign, pledge, hypothecate or otherwise dispose of the Securities (or solicit any offers to buy, purchase, or otherwise acquire any of the Securities), except in compliance with the Securities Act.

            4.2  Accredited
Investor. Such Purchaser is an "accredited investor" (as that term is defined in Rule 501 of Regulation D under the Securities Act) and by reason of its business and financial experience, it has such knowledge, sophistication and experience in business and financial matters as to be capable of

25

evaluating the merits and risks of the prospective investment, is able to bear the economic risk of such investment and is able to afford a complete loss of such investment.

            4.3     Restricted
Securities. Each Purchaser understands that the Securities it is purchasing are characterized as "restricted securities" under the federal securities laws inasmuch as they are being acquired from ClimaChem in a transaction not involving a public offering and that under such laws and applicable regulations such Securities may be resold without registration under the Securities Act, only in certain limited circumstances.  In this connection, such Purchaser represents that it is familiar with Rule 144 of the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

           4.4     Corporate
Existence.  Such Purchaser is an entity duly organized, validly existing and in good standing under the laws of the State of its organization.

           4.5     Power,
Authorization; Enforceable Obligations.  The execution, delivery and performance by such Purchaser of this Agreement and the other Transaction Documents to be executed by it:  (i) are within such Purchaser's corporate or other power; (ii) have been duly authorized by all necessary corporate or other action; (iii) are not in contravention of any provision of such Purchaser's certificate of incorporation or by-laws or other organizational documents; and (iv) will not violate any law or regulation, or any order or decree of any court or governmental instrumentality binding on such Purchaser.  This Agreement and the other Transaction Documents to which such Purchaser is a party have each been duly executed and delivered by such Purchaser and constitute the legal, valid and binding obligations of such Purchaser, enforceable against it in accordance with their respective terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors' rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity).

5.  CREDIT PARTIES' REPRESENTATIONS AND WARRANTIES

           Each Credit Party, and Parent, to the extent any representation relates to Parent, jointly and severally, makes the following representations and warranties, each as of the date hereof, to each Purchaser, each and all of which shall survive the execution and delivery of this Agreement and the Closing hereunder (for avoidance of doubt, nothing herein shall be construed to require any Credit Party to update the representations and warranties after the date thereof):

            5.1     Authorized
and Outstanding Shares of Capital Stock.  After giving effect to the Closing, the authorized capital stock of Parent consists of 75,000,000 shares of common stock, $0.10 par value, of which 11,935,583 shares are issued and outstanding, and 250,000 shares of preferred stock, $100 par value, of which 1,294 shares are issued and outstanding, 5,000,000 shares of class C preferred stock, no

26

par value, of which 907,250 shares are issued and outstanding, 20,000 shares of Class B preferred stock, $100 par value, of which 20,000 shares are issued and outstanding and 1,000,000 shares of Class D preferred stock, no par value, of which 1,000,000 shares are issued and outstanding.  All of such issued and outstanding shares are validly issued, fully paid and non-assessable.  Except as set forth on Schedule 4.1, (i) there is no existing option, warrant, call, commitment or other agreement to which Parent is a party requiring, and there are no convertible securities of Parent outstanding which upon conversion would require, the issuance of any additional shares of Stock of Parent or other securities convertible into shares of equity securities of ClimaChem, and (ii) there are no agreements to which Parent is a party with respect to the voting or transfer of the Stock of Parent.  There are no stockholders' preemptive rights or rights of first refusal or other similar rights with respect to the issuance of Stock by Parent.  True and correct copies of the certificate of incorporation and by-laws of Parent have been delivered to each Purchaser.  Parent is the record and beneficial owner of 95% of the issued and outstanding shares of capital stock of ClimaChem and any right to acquire the same, and Prime Financial Corporation, a wholly owned subsidiary of Parent, is the record and beneficial owner of 5% of the issued and outstanding shares of capital stock of ClimaChem and any right to acquire the same.

           5.2     Authorization
and Issuance of the Securities.  The issuance of the Securities has been duly authorized by all necessary corporate action on the part of ClimaChem and Parent and, upon delivery to each Purchaser of the Securities against payment in accordance with the terms hereof, the Securities will have been validly issued, free and clear of all pledges, liens, encumbrances and preemptive rights.  The issuance of shares of Common Stock upon exercise of the Warrants has been duly authorized by all necessary corporate action on the part of Parent and, when issued upon such exercise, such Common Stock will have been validly issued and fully paid and non-assessable.  Parent has duly reserved 595,585 shares of Common Stock for issuance pursuant to the terms of the Warrants.

            5.3     Securities
Laws.  In reliance on the investment representations contained in Sections 4.1 and 4.2 hereof, the offer, issuance, sale and delivery of the Securities, as provided in this Agreement, are exempt from the registration requirements of the Securities Act and all applicable state securities laws, and are otherwise in compliance with such laws.  Neither ClimaChem, Parent nor any Person acting on their behalf has taken or will take any action (including, without limitation, any offering of any securities of ClimaChem or Parent under circumstances which would require the integration of such offering with the offering of the Securities under the Securities Act and the rules and regulations of the SEC thereunder) which might subject the offering, issuance or sale of the Securities to the registration requirements of Section 5 of the Securities Act.

           5.4     Corporate
Existence.  ClimaChem, Parent and each of the Credit Parties, (i) is a corporation duly organized, validly existing and in good standing under the laws of the State of its incorporation, as set forth on Schedules 5.4 or 5.5; (ii) is duly qualified as a foreign corporation and in good standing under the

27

laws of each jurisdiction where its ownership or lease of property or the conduct of its business requires such qualification (except for jurisdictions in which such failure to so qualify or to be in good standing would not be reasonably likely to have a Material Adverse Effect); (iii) has the requisite corporate power and authority and the legal right to own, pledge, mortgage or otherwise encumber and operate its properties, to lease the property it operates under lease, and to conduct its business as now being conducted and as proposed to be conducted; and (iv) except for Slurry Explosive Corporation and Universal Tech Corporation, with respect to their operation of the Hallowell, Kansas facility, has, or has applied for, all licenses, permits, consents or approvals from or by, and has made all filings with, and has given all notices to, all Governmental Authorities having jurisdiction, to the extent required for such ownership, operation and conduct, the failure of which would be reasonably likely to have a Material Adverse Effect.

           5.5     Subsidiaries. 
There currently exist no Subsidiaries of ClimaChem other than as set forth on Schedule 5.5 hereto, which sets forth such Subsidiaries, together with their respective jurisdictions of organization,  and the authorized and outstanding capital Stock of each such Subsidiary, by class and number and percentage of each class owned by ClimaChem or any other Person.  There are no options, warrants, rights to purchase or similar rights covering capital Stock for any such Subsidiary.

           5.6      Corporate
Power; Authorization; Enforceable Obligations.  The execution, delivery and performance by each Credit Party and Parent of this Agreement, the other Transaction Documents to which each is a party and all instruments and documents to be delivered by each Credit Party and Parent, and the consummation of the other transactions contemplated by any of the foregoing:  (i) are within such Person's corporate power and authority; (ii) have been duly authorized by all necessary or proper corporate action; (iii) are not in contravention of any provision of such Person's certificate of incorporation or by-laws; (iv) will not violate any law or regulation, or any order or decree of any court or governmental instrumentality applicable to such Person; (v) will not conflict with or result in the breach or termination of, constitute a default under or accelerate any performance required by, any Material Contract; (vi) will not result in the creation or imposition of any Lien upon any of the property of such Person or any of its Subsidiaries other than Permitted Liens and the Lien granted pursuant to this Agreement; and (vii) do not require the consent or approval of, or any filing with, any Governmental Authority or any other Person (except to the extent previously obtained or made or those required to perfect the Purchasers' security interest, such as filing of financing statements and/or mortgages with appropriate Governmental Authorities).  On or prior to the Closing Date, each of this Agreement and the other Transaction Documents shall have been duly executed and delivered by each Credit Party and Parent party thereto and each shall then constitute a legal, valid and binding obligation of such Person, enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors' rights and remedies generally, and subject, as to enforceability, to general principles of equity,

28

including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity).

           5.7     Financial
Statements.  The audited consolidated balance sheets of Parent and its Subsidiaries and ClimaChem and its Subsidiaries as at December 31, 2001 (the "Balance Sheet"), and the related consolidated statements of income and cash flows for the year then ended, with the opinion thereon of Ernst & Young, LLP, copies of which have previously been delivered to each Purchaser, have been, except as noted therein, prepared in conformity with GAAP consistently applied throughout the periods involved and present fairly in all material respects the consolidated financial position of Parent and its Subsidiaries and ClimaChem and its Subsidiaries, as applicable, as at the dates thereof, and the consolidated results of their operations and cash flows for the periods then ended.

                 (b)   Except as set forth on Schedule 5.7, no Credit Party nor any of its Subsidiaries has any material obligations, contingent or otherwise, including, without limitation, liabilities for Charges, except such Charges as are being contested in good faith and for which appropriate reserves have been established, or unusual forward or long-term commitments which are not reflected in the Balance Sheet, other than those incurred since December 31, 2001, in the ordinary course of business.

                   (c)
  Except as set forth on Schedule 5.7, no dividends or other distributions have been declared, paid or made upon any shares of capital Stock of any Credit Party or Parent, nor have any shares of capital Stock of any Credit Party or Parent been redeemed, retired, purchased or otherwise acquired for value by such Credit Party or Parent since December 31, 2001.

            5.8     Ownership
of Property.  Except as set forth on Schedule 5.8, none of the Credit Parties nor any of its Subsidiaries owns any real estate.  Each Credit Party and its Subsidiaries has good and marketable and insurable fee simple title to its owned real property, free and clear of all Liens, except Permitted Liens.  Each Credit Party and its Subsidiaries has valid and marketable leasehold interests in the leases described on Schedule 5.8 hereto, and, except as set forth on Schedule 5.8, good and marketable title to, or valid leasehold interests in, all of its other properties and assets free and clear of all Liens, except Permitted Liens.

                  (b)   
All real property leased by each Credit Party and its Subsidiaries is set forth on Schedule 5.8.  Each of such leases is valid and enforceable in accordance with its terms (subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors' rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity)) and is in full force and effect.  The Credit Parties have delivered or made available to each Purchaser true and complete copies of each of such leases set forth on Schedule 5.8 and all documents affecting the rights or obligations of the Credit Parties or any of

29

their Subsidiaries, including, without limitation, any non-disturbance and recognition agreements, subordination agreements, attornment agreements and agreements regarding the term or rental of any of the leases.  Except as set forth on Schedule 5.8, none of the Credit Parties, any of its Subsidiaries nor, to its knowledge, any other party to any such lease is in default of its obligations thereunder or has delivered or received any notice of default under any such lease, nor has any event occurred which, with the giving of notice, the passage of time or both, would constitute a default under any such lease involving more than $500,000 per year.

8.     TRIGGERING CONDITION

            If, as of the end of any fiscal quarter beginning after the Closing Date, ClimaChem fails to maintain EBITDA for the twelve-month period ending on the last day of any such fiscal quarter equal to at least $17,000,000 (a "Trigger Event"), then, within 180 days of the end of such fiscal quarter, ClimaChem shall pay to the Purchasers an amount equal to 33.3% of then outstanding principal of the Notes plus any Additional Interest applicable to such payment and all accrued and unpaid Cash Interest (the "Trigger Failure Amount"); provided, however, that if as of the end of each of the two fiscal quarters immediately following any Trigger Event, ClimaChem maintains EBITDA for the twelve-month period ending on the last day of the respective fiscal quarter equal to at least $17,000,000, then, within 210 days of such Trigger Event, ClimaChem shall pay to the Purchasers an amount equal to 10.0% of then outstanding principal of the Notes plus any Additional Interest applicable to such payment and all accrued and unpaid Cash Interest instead of the Trigger Failure Amount.  If ClimaChem defaults in the making of any such payment, the Purchasers may, at any time after such default, at the sole expense of the Credit Parties, hire an advisor reasonably acceptable to ClimaChem (which consent shall not be unreasonably withheld) to assist ClimaChem in obtaining financing or selling its assets or its business, in separate parts or in its entirety, sufficient to pay all Obligations.  All proceeds from any such sales of assets shall be paid to the Purchasers for application to the Obligations, subject to the prior rights of any first Lien on such assets pursuant to the Foothill Loan Agreement.

            Any Purchaser may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in its best interests, including any action (or the failure to act) pursuant to the Loan Documents.

The rights of the Purchasers under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Purchasers may have.

54

10.     INDEMNIFICATION

11.     COLLATERAL AGENT

           11.1     Collateral
Agency Provisions.  (a)  Appointment.  Guggenheim Investment Management, LLC is hereby appointed to act on behalf of all the Purchasers as the Collateral Agent under this Agreement, and the other Loan Documents. The provisions of this Section 11.1 are solely for the benefit of the Collateral Agent and the Purchasers,  and no Credit Party nor any other Person shall have any rights as a third party beneficiary of any of the provisions hereof.  In performing its functions and duties under this Agreement, the Collateral Agent shall act solely as an agent of the Purchasers and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for any Credit Party or any other Person. The Collateral Agent shall have no duties or responsibilities except for those expressly set forth in this Agreement. The duties of the Collateral Agent shall be mechanical and administrative in nature and the Collateral Agent shall not have, or be deemed to have, by reason of this Agreement or otherwise a fiduciary relationship in respect of any Purchaser.  The Purchasers hereby authorize the Collateral Agent to execute the Intercreditor Agreement, dated as of the date hereof, with Foothill Capital Corporation in substantially the same form and substance as previously delivered to the Purchasers.

                 (b)     Actions.  If the Collateral Agent shall request instructions from the Required Holders or all Purchasers affected thereby with respect to any act or action (including failure to act) in connection with this Agreement, then the Collateral Agent shall be entitled to refrain from such act or taking such action unless and until the Collateral Agent shall have received instructions from the Required Holders or all Purchasers affected thereby, as the case may be, and the Collateral Agent shall not incur liability to any Person by reason of so refraining. The Collateral Agent shall be fully justified in failing or refusing to take any action

55

hereunder (a) if such action would, in the opinion of the Collateral Agent, be contrary to law or the terms of this Agreement, (b) if such action would, in the opinion of the Collateral Agent, expose the Collateral Agent to any liability or (c) if the Collateral Agent shall not first be indemnified to its satisfaction against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Without limiting the foregoing, no Purchaser shall have any right of action whatsoever against the Collateral Agent as a result of the Collateral Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Holders or all affected Purchasers, as applicable.

                (c)     Collateral Agent's Reliance. etc.  Neither the Collateral Agent nor any of its Affiliates nor any of their respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for damages caused by its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Collateral Agent: (a) may treat the payee of any Note as the holder thereof until the Collateral Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to the Collateral Agent; (b) may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Purchaser and shall not be responsible to any Purchaser for any statements, warranties or representations made in or in connection with this Agreement; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of any Credit Party or to inspect the Collateral including the books and records of any Credit Party; (e) shall not be responsible to any Purchaser for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto or thereto; and (f) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties.

                (d)     Purchaser Credit Decisions.  Each Purchaser acknowledges that it has, independently and without reliance upon the Collateral Agent or any other Purchaser and based on such financial statements and other documents and information as it has deemed appropriate, made its own credit and financial analysis of the Credit Parties and its own decision to enter into this Agreement. Each Purchaser also acknowledges that it will, independently and without reliance upon the Collateral Agent or any other Purchaser and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. Each Purchaser acknowledges the potential conflict of interest of each other Purchaser as a result of the Purchasers holding disproportionate interests in the Notes, and expressly consents to, and waives any claim based upon, such conflict of interest. 

56

                (e)     Successor Collateral Agent.  The Collateral Agent may resign at any time by giving not less than 30 days' prior written notice thereof to the Purchasers and ClimaChem. Upon any such resignation, the Required Holders shall have the right to appoint a successor Collateral Agent. If no successor Collateral Agent shall have been so appointed by the Required Holders and shall have accepted such appointment within 30 days after the resigning Collateral Agent's giving notice of resignation, then the resigning Collateral Agent may, on behalf of the Purchasers, appoint a successor Collateral Agent, which shall be a Purchaser, if a Purchaser is willing to accept such appointment, or otherwise shall be a commercial bank or financial institution or a subsidiary of a commercial bank or financial institution if such commercial bank or financial institution is organized under the laws of the United States of America or of any State thereof and has a combined capital and surplus of at least $300,000,000. If no successor Collateral Agent has been appointed pursuant to the foregoing by the 30th day after the date such notice of resignation was given by the resigning Collateral Agent, such resignation shall become effective and the Required Holders shall thereafter perform all the duties of the Collateral Agent hereunder until such time, if any, as the Required Holders appoint a successor Collateral Agent as provided above. Prior to the occurrence and continuation of an Event of Default any successor Collateral Agent appointed by the Collateral Agent or the Required Holders shall be subject to the prior approval of ClimaChem, such approval not to be unreasonably withheld or delayed. Upon the acceptance of any appointment as the Collateral Agent hereunder by a successor Collateral Agent, such successor Collateral Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the resigning Collateral Agent. Upon the earlier of the acceptance of any appointment as the Collateral Agent hereunder by a successor Collateral Agent or the effective date of the resigning Collateral Agent's resignation, the resigning Collateral Agent shall be discharged from its duties and obligations under this Agreement, except that any indemnity rights or other rights in favor of such resigning Collateral Agent shall continue. After any resigning Collateral Agent's resignation hereunder, the provisions of this Section 11.1 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Collateral Agent under this Agreement.

                 (f)      Indemnification by the Purchasers.  The Purchasers agree to indemnify the Collateral Agent (to the extent the Collateral Agent is not reimbursed by the Credit Parties and without limiting the obligations of ClimaChem hereunder), ratably on a pro rata basis based on the principal amount outstanding under the Notes from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Collateral Agent in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted by the Collateral Agent in connection therewith; provided, however, that no Purchaser shall be liable to the extent it is finally judicially determined that such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements arose primarily from the Collateral Agent's gross negligence or willful misconduct.

57

           Purchaser by virtue of any of the Loan Documents;
