            Notwithstanding the amounts set forth under the heading "Facility
            Amount", and except as otherwise provided with respect to LSB,
            Borrowers are not limited to the specific Facility Amount if they
            would otherwise have sufficient Availability to exceed such
            Facility Amounts, but in no event will the Loans outstanding to
            all Borrowers exceed $75,000,000 in the aggregate.  With respect
            to LSB, the Facility Amount shall never be more than $8,400,000.

            (b)   AMOUNT OF REVOLVING CREDIT FACILITY:  Each Facility shall   
                  provide for advances of up to (i) eighty-five percent (85%)
            of the net amount of eligible accounts receivable of the
            applicable Borrowers and (ii) sixty percent (60%) of eligible
            inventory of the applicable Borrower, valued at the lower of cost
            (on a FIFO basis) or market value.  Collections of accounts (other
            than proceeds from the sale or other disposition of Borrowers'
            fixed assets, i.e. equipment and real estate) would be transferred
            daily to Lender from one or more restricted or lock box accounts
            and would be credited to the loan balances of the appropriate
            Borrower one (1) business day after receipt of good funds by
            Lender.  Advances to all Borrowers with respect to eligible
            accounts receivables that are more than 180 days from the invoice
            date shall not exceed the lesser of (i) $1,500,000 or (ii) five
            percent (5%) of the gross eligible accounts receivable
            availability under the Total Credit Facility.  Advances made under
            each Facility with respect to eligible inventory shall not exceed
            the following amounts:

                                          INVENTORY
               FACILITY                 ADVANCE AMOUNT

            Facility One                  $  3,500,000

            Facility Three                $  3,500,000

            Facility Four                 $  3,500,000

            Facility Five                 $  3,500,000

            Facility Six                  $ 15,000,000

            Notwithstanding the amounts set forth under the heading "Inventory
            Advance Amount", Borrowers are not limited to the specific
            Inventory Advance Amount if they would otherwise have sufficient
            Availability based on Eligible Inventory to exceed such Inventory
            Advance Amount, but in no event will the Loans outstanding to all
            Borrowers based on Eligible Inventory exceed $37,500,000 in the
            aggregate.

            (c)   ELIGIBLE COLLATERAL:  Collateral eligibility and the
            establishment of reasonable reserves against borrowing
            availability shall be determined by Lender in its reasonable
            discretion, provided, however, that the following accounts shall
            in any event be ineligible:  (i)  accounts past due for more than
            90 days if their terms are 90 days or less, (ii) accounts past due
            for more than 30 days if their terms are between 91 and 360 days,
            (iii) intercompany accounts, (iv)  note receivables (other than as
            part of chattel paper in which Lender has a perfected security
            interest), (v) foreign accounts that would otherwise be eligible
            but which are in excess of five percent (5%) of the gross eligible
            account receivables, without consideration of the foreign
            accounts, and (vi) non-trade receivables and, provided further
            that the following inventory shall be ineligible:  i) slow moving,
            (ii) work-in-progress, (iii) fifty percent (50%) of inventory
            classified as "components" other than the "components" at Climate
            Master, Inc. and International Environmental Corp., (iv) inventory
            in transit (unless such inventory is covered by insurance and is
            owned by Borrower and in which Lender has a perfected security
            interest), (v) service parts, (vi) used parts, (vii) returns,
            (viii) defective, (ix) off-site, (x) finished goods reserves as
            shown on the books of the Borrowers, (xi) containers, and (xii)
            "trade-in inventory" except that the trade-in equipment inventory
            of Summit may be eligible provided, however, that Lender will only
            advance 25% against such inventory with all such advances not to
            exceed $500,000 in the aggregate at any one time.

            (d)   LETTERS OF CREDIT:  Lender shall upon the Borrowers'
            request, and subject to the existence of sufficient Availability
            with respect to the requesting Borrower, cause to be issued for
            the Borrowers' account, merchandise/documentary letters of credit
            and standby letters of credit.  The aggregate undrawn face amount
            of the letters of credit issued under all Facilities to all
            Borrowers shall not exceed at any one time outstanding $11,000,000
            in the aggregate.  One hundred percent (100%) of the aggregate
            undrawn face amount of outstanding letters of credit will be
            reserved against availability.

            The expiration date of the documentary letters of credit issued
            under each Facility shall not exceed 180 days, but in no event
            extend beyond the Maturity Date. The Expiration date of the
            standby letters of credit may exceed 180 days.

      2.    MATURITY DATE:  The Facilities shall mature three years from the
            closing date ("Maturity Date") and all obligations shall then be
            due and payable, provided however, that the Loan Agreement may be
            automatically renewed and the Maturity Date extended for
            successive 13-month terms if no event of default has occurred and
            is continuing and as long as neither party has given the other
            party notice of termination at least 60 days prior to the end of
            the then current term.

      3.    INTEREST RATES:
            (a)   INTEREST RATE:  The unpaid balance on the revolving loans
                  outstanding under each Facility shall bear interest at a
                  rate equal to:

                  (i)   a fluctuating per annum rate equal to one-half percent
                        (.50%)  in excess of the Reference Rate as quoted from
                        time to time by Bank of America NT & SA, San
                        Francisco, California ("Bank of America") ("Reference
                        Rate Loans"); or

                  (ii)  at Borrower's option, 2.875 percent (2.875%) plus the
                        LIBOR rate for 90-day loans as quoted from time to
                        time by Bank of America ("LIBOR Loans").  Each LIBOR
                        Loan shall be for a $5,000,000 minimum amount, and
                        shall be subject to certain restrictions relating to
                        terms and incremental amounts.

                  All interest shall be calculated on the basis of a 360 day
                  year for actual days elapsed.  Interest on all loans shall
                  be payable monthly on the first day of each month.

            (b)   DEFAULT RATE:  If any such default occurs under any
                  Facility, then, from the date such event of default occurs
                  until it is cured, the Borrowers under each Facility shall
                  pay interest on the unpaid balance of the revolving loans at
                  a per annum rate two percent (2%) greater than the rate of
                  interest specified above and the letter of credit fee shall
                  be increased by two percent (2%).

            (c)   REFERENCE RATE:  "Reference Rate" means the rate of interest
                  publicly announced from time to time by Bank of America as
                  its reference rate.  It is a rate set by Bank of America
                  based upon various factors, including Bank of America's
                  costs and desired return, general economic conditions, and
                  other factors, and it is used as a reference point for
                  pricing some loans.  However, Bank of America may price
                  loans at, above, or below the reference rate.

      4.    FEES:  Borrowers shall pay to Lender the following fees:

            (a)   CLOSING FEE:  A one time closing fee ("Closing Fee") for
                  each Facility equal to .50 percent of the applicable
                  Facility Amount ($375,000 in the aggregate) which shall be
                  fully earned and payable at closing.

            (b)   UNUSED LINE FEE:  An unused line fee, payable monthly, for
                  each Facility at the rate per annum equal to half percent
                  (.5%), on the difference between (a) the Facility Amount for
                  each Facility and (b) the sum of (i) the average daily
                  unpaid balance of the revolving loans outstanding under such
                  Facility during the month with the unpaid balance calculated
                  by applying payments immediately upon receipt, and (ii) the
                  average daily balance of the letters of credit outstanding
                  during the month.

            (c)   LETTER OF CREDIT FEES:  The Borrowers under each Facility
                  shall pay monthly to Lender a fee equal to one percent
                  (1.0%) per annum of the face amount of all outstanding
                  letters of credit.  Borrowers shall also pay to Lender all
                  commissions and processing fees incurred by Lender on the
                  Borrowers' behalf in arranging for the opening and
                  maintenance of the letters of credit, including all charges
                  of the issuing bank.

            (d)   EARLY TERMINATION FEE:  In the event that any Facility is
                  for any reason whatsoever terminated prior to the initial
                  term, the Borrowers under each Facility shall pay Lender an
                  early termination fee in the amounts set forth below, in
                  order to compensate Lender for its reasonable expenses and
                  its loss of anticipated profits.  If the effective date of
                  the termination of the Facilities occurs in the first year
                  of the term, then the early termination fee for each
                  Facility shall be three percent (3.0%) of the average daily
                  balance of the loans and letters of credit outstanding
                  during the 180 days (or any portion thereof) preceding the
                  effective date of termination; in the second year, the early
                  termination fee shall be two percent (2.0%) of the average

                  daily balance of the loans and letters of credit outstanding
                  during the 180 days preceding the effective date of
                  termination; and in the third year, the early termination
                  fee shall be one percent (1.0%) of the loans and letters of
                  credit outstanding during the 180 days preceding the
                  effective date of termination.  If at the time of prepayment
                  any LIBOR Loans are outstanding, then the Borrowers shall
                  pay to Lender additional sums to compensate for the
                  cancellation of part or all of the LIBOR financing.  Prior
                  to an Event of Default which is continuing, the Borrower may
                  prepay at any time all outstanding Obligations due hereunder
                  without penalty or premium if (i) Lender under any condition
                  or for any reason changes the advance rates relating to
                  Eligible Accounts or Eligible Inventory from that set forth
                  in the definition of Availability, or (ii) as a result of or
                  in connection with or arising out of a public offering by
                  LSB of its securities (equity or debt) after the closing
                  date, the Borrower desires to prepay any of the Obligations
                  or terminate the Loan Agreement.

      5.    COLLATERAL:  All loans, advances, obligations, liabilities and
            indebtedness of the Borrowers to Lender shall be secured by valid,
            perfected and enforceable, first priority liens upon and security
            interests in all of the Borrowers' present and future accounts,
            contract rights, instruments, documents, chattel paper, general
            intangibles, patents, trademarks, trade names, inventory, and all
            capital stock of the Borrowers (other than LSB, EDC and Slurry)
            and certain affiliates and guarantors, including, but not limited
            to, the Affiliate Guarantors.  The parties agree that the capital
            stock of DSN Corporation, Prime Financial Corporation and its
            subsidiaries, and LSB Holdings, Inc. and its subsidiaries other
            than the subsidiaries who are Affiliate Guarantors) will not be
            pledged to Lender.  In addition, Lender shall have the right to
            take possession of all chattel paper but regardless of whether
            Lender exercises such right, no Borrower will pledge or deliver
            such chattel paper to other third parties without Lender's prior
            written consent thereto.  All of the Facilities shall be
            coterminous, cross-collateralized and cross-guaranteed with each
            other, except that the Borrowers under Facility Six shall not
            guarantee and the collateral thereunder shall not secure the other
            Facilities.  In addition, it is agreed and understood by Lender
            that certain general intangibles have previously been pledged by
            EDC and Slurry to Household Commercial Financial Services, Inc.
            ("Household Bank") and may not be pledged to Lender so long as
            loans are outstanding by Household Bank to EDC and Slurry.

      6.    GUARANTEES.  The Borrowers under each Facility, other than the
            Borrowers under Facility Six, shall guarantee the obligations of
            the Borrowers under the other Facilities.  The obligations of LSB
            and the other Borrowers to Lender shall be secured by secured
            guarantees (the "Affiliate Guarantees") from the entities listed
            on Exhibit A (the "Affiliate Guarantors").  The Affiliate
            Guarantees shall contain grants of security interests in the same
            type of collateral as is described in Section 5 of this letter. 
            In addition, each Affiliate Guarantor shall execute a note and
            security agreement in favor of LSB (the "Guarantor Chattel Paper")
            and LSB shall pledge and deliver to Lender all such Guarantor
            Chattel Paper.

      7.    CONDITIONS PRECEDENT:  The extension of the aforementioned
            financing arrangement by Lender would necessarily be subject to
            the fulfillment of a number of conditions, including, but not
            limited to, the following:


            (a)   The execution and delivery, in form and substance acceptable
                  to Lender and its counsel, of Lender's customary agreements,
                  documents, guarantees, instruments, financing statements,
                  landlords' waivers, consents, documents indicating
                  compliance with all applicable federal and state
                  environmental laws and regulations, evidences of corporate
                  authority, certificates, insurance certificates evidencing
                  that Borrower has obtained insurance in amounts satisfactory
                  to Lender, opinions of counsel and such other writings to
                  confirm and effectuate the financing arrangements as may be
                  required by Lender and its counsel.

            (b)   The loan and security agreement for each Facility shall
                  contain financial covenants, acceptable to Lender, with
                  respect to leverage ratio, minimum tangible net worth, and
                  maximum capital expenditures, together with such other
                  representations, warranties, and covenants deemed
                  appropriate by Lender for this transaction, including
                  restrictions on certain distributions, loans, advances,
                  management fees, and similar transfers of funds or other
                  assets by Borrowers and an agreement by Borrowers to pay all
                  legal fees and audit and appraisal expenses incurred by
                  Lender together with an allocated charge of $500 per day per
                  auditor, with audits no more that three times per year prior
                  to an Event of Default to be charged to Borrower's account. 
                  Any additional audits prior to an Event of Default will be
                  at Lender's expense.  The loan agreement shall, without
                  limitation, (i) permit transfer of funds by and among the
                  Borrowers and Affiliate Guarantors, but advances and

                  Borrower, and no material breach under any material
                  agreement or contract to which any Borrower or Affiliate

                  effect on the business, condition (financial or otherwise),
                  operations, performance, or properties of the Borrowers and
                  Affiliate Guarantors taken as a whole or which could impair
                  the ability of the Borrowers and Affiliate Guarantors taken
                  as a whole to perform satisfactorily under the proposed
                  financing arrangement, or (ii) in Lender's judgment, would
