4.       EXTRAORDINARY ITEM - EARLY EXTINGUISHMENT OF DEBT

         As a result of the early retirement of the Chemical Bank debt and the
partial payment on the CIT note, the Company recognized an extraordinary expense
of $93,000 (net of the related tax benefit of $54,000) for the write down of
deferred financing expenses related to these debts during the three months ended
February 29, 1996.

5.       EARNINGS PER SHARE

         Net earnings per share is computed using the weighted average number of
shares of common stock outstanding for the period. When dilutive, stock options
and warrants are included as share equivalents using the treasury stock method.
In calculating net earnings per share, preferred dividends of $24,718 and
$71,746 reduced the net earnings available to common stockholders for the three
months and nine months ended May 31, 1997, respectively. Fully diluted net
earnings per common share is not significantly different from primary net
earnings per common share.

6.       RECENT DEVELOPMENTS

         On April 30, 1997, the Company entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Chart Industries, Inc. ("Chart") and
certain of Chart's wholly-owned subsidiaries pursuant to which the Company will
become an indirect, wholly-owned subsidiary of Chart (the "Merger"). As a result
of the Merger, each outstanding share of common stock of the Company will be
converted into the right to receive $2.75 in cash, without interest. The Merger
Agreement and the Merger are subject to approval by the stockholders of the
Company. A Special Meeting of the Company's stockholders is scheduled for July
31, 1997 in order to vote upon approval and adoption of the Merger Agreement and
the transactions contemplated thereby.

Item 2.  Management's Discussion and Analysis of Financial
         Condition and Results of Operations

         This Quarterly Report on Form 10-Q contains certain forward-looking
statements that involve risks and uncertainties. Discussions containing such
forward-looking statements may be found in the materials set forth below in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." The Company's actual results could differ materially from those
anticipated in the forward-looking statements.

Results of Operations - Three and Nine
Months Ended May 31, 1996 and May 31, 1997

         Contract revenue decreased 6.7% to $7.7 million for the three months
ended May 31, 1997 from $8.2 million for the three months ended May 31, 1996.
Contract revenue for the first nine months of the 1997 fiscal year decreased
16.0% to $20.5 million from $24.4 million for the same period of the preceding
year. The quarterly decrease is the result of decreases in revenue from
industrial gas and LNG trailers, MRI cryostats and components, and LNG
dispensing equipment, which decreased $1.4 million, $834,000 and $141,000,
respectively, over the corresponding period in the prior year. The Company does
not believe that these decreases are indicative of a long-term trend. These
decreases were offset somewhat by increased revenues from TVAC'r' intermodal
containers which increased $1.7 million over the corresponding 1996 period. For
the nine month period the decrease was primarily the result of the decrease in
revenues from industrial gas and LNG trailers, MRI cryostats and components, and
LNG dispensing equipment, which decreased $4.5 million, $2.0 million and
$679,000, respectively, over the corresponding nine month period in the prior
year. These decreases were offset somewhat by increased revenues from TVAC'r'
intermodal containers and cryogenic spares, which increased $2.7 million and
$327,000, respectively, over the corresponding 1996 period.

         Gross profit for the three months ended May 31, 1997 decreased 30.4% to
$1.3 million, or 16.5% of contract revenue, from $1.8 million, or 22.2% of
contract revenue, for the three months ended May 31, 1996. Gross profit for the
first nine months of the 1997 fiscal year decreased 17.5% to $4.0 million, or
19.6% of contract revenue, from $4.9 million, or 20.0% of contract revenue, for
the same period of the previous year. The gross profit decrease for the quarter
was the result of the reduced revenues combined with lower sales prices on
trailers and unabsorbed manufacturing overhead expenses due to the reduced level
of shop activity. For the nine month period the decrease was primarily due to
the reduced revenues and increased unabsorbed manufacturing overhead expenses.

         Selling, general and administrative expenses increased $14.5% to $1.0
million for the three months ended May 31, 1997 from $894,000 for the three
months ended May 31, 1996, and increased as a percentage of contract revenue to
13.3% from 10.9% during the same period. Selling, general and administrative
expenses for the first nine months of fiscal 1997 increased 3.2% to $2.5 million
or 12.2% of contract revenue from $2.4 million or 10.0% of contract revenue
compared to the corresponding period in the prior year. The increase is
primarily due


                                       11

to the legal and consulting expenses related to the anticipated merger with
Chart Industries, Inc., and to a lesser extent is due to increased sales
expenses. Research and development costs decreased to $(14,000) for the three
months ended May 31, 1997 from $277,000 for the three months ended May 31, 1996,
and to $315,000 for the first nine months of fiscal 1997 compared to $708,000
for the comparable period of the prior year. The credit in the current period is
due to the timing of billings for the reimbursement of TADOPTR development costs
under a development contract. The decrease in expenses for both the three and
nine month periods is primarily the result of the decrease in expenditures for
the development of new LNG products compared to the prior year. Amortization
expense decreased to $59,000 for the three months ended May 31, 1997 from
$87,000 for the three months ended May 31, 1996, and to $181,000 for the first
nine months of fiscal 1997 compared to $259,000 for the comparable period of the
prior year due to the completion of the organization cost amortization in the
prior year.

         Interest expense for the three months ended May 31, 1997 increased 2.2%
to $231,000 from $226,000 for the three months ended May 31, 1996 and increased
8.4% to $722,000 for the first nine months of the 1997 fiscal year from $666,000
for the same period of the preceding year. This increase in the current quarter
is due to increased debt issuance cost amortization due to the repayment of the
balance of the subordinated debt during the quarter. The cumulative increase is
primarily due to an increased average level of borrowing. Other non-operating
items resulted in income of $213,000 for the three months ended May 31, 1997,
compared to an expense of $5,000 in the comparable period of 1996, and income of
$269,000 in the first nine months of this fiscal year compared to an expense of
$1,000 for the first nine months of the 1996 fiscal year. The increase in income
in the current period is the result of a gain on the sale of capital equipment.
In addition, the increase in income in the nine month period includes a $49,000
profit on the sale of the Company's interest in Applied LNG Technologies USA,
LLC.

         Income tax expense decreased to $68,000 for the three months ended May
31, 1997 from $126,000 for the three months ended May 31, 1996 and to $208,000
for the first nine months of this fiscal year from $300,000 for the first nine
months of the prior year. The expense in both years is the result of taxable
income for the periods and estimated annual tax rates.

         The resulting net income decreased to $116,000 for the three months
ended May 31, 1997 from $212,000 for the corresponding prior year period, and
decreased to $355,000 for the nine months ended May 31, 1997 from $510,000 for
the corresponding nine month period of the prior year. This change is the result
of the cumulative effect of the above factors.

Liquidity and Capital Resources

         At May 31, 1997, the Company's working capital was $9.7 million, which
represented a current ratio of 3.7 to 1. Also, the Company's outstanding
indebtedness under the Credit Agreement with FBS Business Finance Corporation
was $6.9 million, of which $499,000 represented term indebtedness and $6.4
million represented revolving indebtedness.

         Cash flow from operations for the nine months ended May 31, 1997
resulted in cash provided in the amount of $2.8 million compared to cash used of
$1.3 million in the same period of the prior year. In the current year, cash was
provided primarily by the decreases in accounts receivable and by net income. In
the nine months ended May 31, 1996 cash was used to increase accounts
receivable, which was somewhat offset by the decrease in costs and estimated
earnings in excess of billings on uncompleted contracts and by net income.

         The Company believes that its existing capital resources, together with
cash flow from future operations will be sufficient to meet its short term
working capital needs. Additional financing may be required for future expansion
of operations.

Recent Developments

         On April 30, 1997, the Company entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Chart Industries, Inc. ("Chart") and
certain of Chart's wholly-owned subsidiaries pursuant to which the Company will
become an indirect, wholly-owned subsidiary of Chart (the "Merger"). As a result
of the Merger, each outstanding share of common stock of the Company will be
converted into the right to receive $2.75 in cash, without interest. The Merger
Agreement and the Merger are subject to approval by the stockholders of the
Company. A Special Meeting of the Company's stockholders is scheduled for July
31, 1997 in order to vote upon approval and adoption of the Merger Agreement and
the transactions contemplated thereby.

                   SECOND AMENDMENT TO CREDIT AND SECURITY AGREEMENT

        THIS SECOND AMENDMENT (this "Amendment"), dated as of January 13, 1997,
amends and modifies a certain Credit and Security Agreement, dated as of
December 19, 1995 (as the same may be amended, replaced, restated and/or

FINANCE CORPORATION, a Delaware corporation (the "Lender"), and CRYENCO, INC., a
Colorado corporation, CRYENCO SCIENCES, INC., a Delaware corporation and
CRYENEX, INC., a Delaware corporation (collectively and/or individually the
"Borrower"). Terms not otherwise expressly defined herein shall have the
meanings set forth in the Credit Agreement.

                              PRELIMINARY STATEMENT

        WHEREAS, an event has occurred constituting an Event of Default under
the terms of the Credit Agreement, which the Borrower has requested the Lender
to waive; and

        WHEREAS, the Lender has agreed to waive the Event of Default identified
herein, subject to the terms and conditions set forth in this Amendment.

        NOW, THEREFORE, for value received, the Borrower and the Lender agree as
follows:

        SECTION 1. CAPITALIZED TERMS. Capitalized terms used herein and not
otherwise defined herein shall have the meanings assigned to them in the Credit
Agreement, unless the context shall otherwise require.

        SECTION 2.    DEFAULT AND WAIVER.

        2.1 Event of Default. Under Section 9.3 of Supplement A to the Credit
        Agreement, the Borrower was to maintain a ratio, as of the last day of
        each fiscal quarter, of the consolidated EBITDA of the Borrower during
        the four consecutive fiscal quarters then ending, to the sum of their
        consolidated unfinanced capital expenditures, cash taxes, interest
        payments, dividends and mandatory debt retirement payments during the
        four consecutive fiscal quarters then ending, of not less than 1.15:1
        from September 1, 1996 through August 31, 1997. The Borrower has advised
        the Lender that as of November 30, 1996, the foregoing ratio was 1.05:1,
        in violation of Section 9.3 of Supplement A.

        2.2 Waiver. Upon the date upon which this Amendment becomes effective,
        the Lender hereby waives the Event of Default described in the preceding
        Section 2.1. The waiver set forth herein shall not constitute a waiver
        by the Lender of any Unmatured Event of Defaults or any other Event of
        Default, if any, under the Credit Agreement, and shall not be, and shall
        not be deemed to

Agreement, and (b) there will exist no Unmatured Event of Default or Event of
Default under the Credit Agreement as amended by this Amendment on such date
which has not been waived by the Lender. The Borrower represents and warrants

registration or declaration with any Person, including without limitation, any
governmental authority, is required in connection with the execution and
delivery by the Borrower of this Amendment or other agreements and documents
executed and delivered by the Borrower in connection therewith or the
performance of obligations of the Borrower therein described, except for those
which the Borrower has obtained or provided and as to which the Borrower has
delivered certified copies of documents evidencing each such action to the
Lender.

        The Borrower warrants that no events have taken place and no
circumstances exist at the date hereof which would give the Borrower assert a
defense, offset or counterclaim to any of the Obligations.

        SECTION 4. AFFIRMATION, FURTHER REFERENCES. The Lender and the Borrower
each acknowledge and affirm that the Credit Agreement, as hereby amended, is
hereby ratified and confirmed in all respects and all terms, conditions and
provisions of the Credit Agreement as amended prior to the date of this

                              ARTICLE IV - GENERAL

         4.1 Waiver. The Borrower has informed the Lender that it was not in
compliance with a loan covenant in its agreement with The CIT Group/Equity
Investments, Inc. ("CIT") regarding consolidated interest coverage for the
period ended February 28, 1997. The failure to comply with such covenant is an
Event of Default under Section 7.1 of the Credit Agreement. Upon the effective
date of this Amendment and compliance with all requirements of Article III
hereof, the Lender hereby waives the Event of Default described in this Section
4.1 for the period ended February 28, 1997. This waiver is limited to the
express terms hereof and to the period described herein and does not apply to
any other Default or Event of Default or any other period. This waiver is not
and shall not be deemed to be a course of dealing or performance upon which the
Borrower may rely with respect to any other Default, Event of Default or request
for a waiver of the same, and the Borrower hereby expressly waives any such
claim.

         4.2 Consent. The Borrower has requested the consent of the Lender to
the sale by CSI of its interest in ALT USA to Jack B. Kelley, Inc. (or an
affiliate thereof) and the use of a portion of the proceeds of such sale to pay
off the Subordinated Debt of the Borrower to CIT. Any such sale by the Borrower
and prepayment of the Subordinated Debt to CIT would violate the covenants set
forth in Sections 6.2 and 6.8 of the Credit Agreement. The Lender hereby
consents to the sale by CSI of its interest in ALT USA to Jack B. Kelley, Inc.
(or an affiliate thereof) for approximately $1,957,000 cash and a note in the
amount of $300,000, and further consents to the prepayment of the Borrower's
Subordinated Debt to CIT in the principal amount of $1,150,000 (plus accrued
interest) from the proceeds of the sale of ALT USA.

         4.3 Expenses. The Borrower agrees to reimburse the Lender upon demand
for all reasonable expenses (including reasonable attorneys' fees and legal
expenses of Dorsey & Whitney LLP, counsel for the Lender) incurred in connection
with the preparation of this Amendment and in enforcing the obligations of the
Borrower hereunder, and to pay and save the Lender harmless from all liability
for any stamp or other taxes which may be payable with respect to the execution
or delivery of this Amendment, which obligations of the Borrower shall survive
any termination of the Credit Agreement.

         4.4 Counterparts. This Amendment may be executed in as many
counterparts as may be deemed necessary or convenient, and by the different
parties hereto on separate counterparts, each of which, when so executed, shall
be deemed an original but all such counterparts shall constitute but one and the
same instrument.

         4.5 Severability. Any provision of this Amendment which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the


                                       -5-

remaining portions hereof or affecting the validity or enforceability of such
provisions in any other jurisdiction.

         4.6  Law. This Amendment shall be a contract made under the laws of the
State of Minnesota, which laws shall govern all the rights and duties hereunder.

         4.7 Successors; Enforceability. This Amendment shall be binding upon
the Borrower and the Lender and their respective successors and assigns, and
shall inure to the benefit of the Borrower and the Lender and the successors and
assigns of the Lender. Except as hereby amended, the Credit Agreement shall
remain in full force and effect and is hereby ratified and confirmed in all
respects.

         3.       REVOLVING LOANS.

                  3.1 PROCEDURE FOR ADVANCES. Any request for an Advance must be
         given so as to be received by the Lender not later than 1:00 p.m.
         (Minneapolis time) two Eurodollar Business Days prior to the date of
         the requested Advance if the Advance is requested as a Eurodollar Rate
         Advance and not later than 1:00 p.m. on the date of the requested
         Advance if the Advance is requested as a Reference Rate Advance. Each
         request for an Advance shall specify (i) the date of the Advance, (ii)
         the amount of the Advance to be made on such date which shall be in a
         minimum amount of $500,000 for Eurodollar Rate Advances or, if more in
         the case of Eurodollar Rate Advances, an integral multiple of $500,000,
         (iii) whether such Advance is to be funded as a Reference Rate Advance
         or a Eurodollar Rate Advance, and (iv) in the case of a Eurodollar Rate
         Advance, the duration of the initial Interest Period applicable
         thereto.

                  3.2 CONVERSIONS AND CONTINUATIONS. On the terms and subject to
         the limitations hereof, the Borrower shall have the option at any time
         and from time to time to convert all or any portion of the Advances
         into Reference Rate Advances or Eurodollar Rate Advances, or to
         continue a Eurodollar Rate Advance as such; provided, however that a
         Eurodollar Rate Advance may be converted or continued only on the last
         day of the Interest Period applicable thereto and no Advance may be
         converted or continued as a Eurodollar Rate Advance if a Default or
         Event of Default has occurred and is continuing on the proposed date of
         continuation or conversion. Advances may be converted to, or continued
         as, Eurodollar Rate Advances only in amounts of $500,000 or an integral
         multiple thereof. The Borrower shall give the Lender written notice of
         any continuation or conversion of any Advance and such notice must be
         given so as to be received by the Lender not later than 3:00 p.m.
         (Minneapolis time) two Eurodollar Business Days prior to requested date
         of conversion or continuation in the case of the continuation of, or
         conversion to, a Eurodollar Rate Advance. Each such notice shall
         specify (a) the amount to be continued or converted, (b) the date for
         the continuation or conversion (which must be (i) the last day of the
         preceding Interest Period for any continuation or conversion of
         Eurodollar Rate Advances, and (ii) a Eurodollar Business Day), and (c)
         in the case of conversions to or continuations as Eurodollar Rate
         Advances, the Interest Period applicable thereto. Any notice given by
         the Borrower under this Section shall be irrevocable. If the Borrower
         shall fail to notify the Lender of the continuation of any Eurodollar
         Rate Advance within the time required by this Section, such Advance
         shall, on the last day of the Interest Period applicable thereto,
         automatically be converted into a Reference Rate Advance of the same

                           (a) Each Eurodollar Rate Advance shall bear interest
                  on the unpaid principal amount thereof during the Interest
                  Period applicable thereto at a rate per annum equal to the sum
                  of (i) the Adjusted Eurodollar Rate for such Interest Period,
                  plus (ii) the Applicable Margin.

                           (b) Each Reference Rate Advance shall bear interest
                  on the unpaid principal amount thereof at a varying rate per
                  annum equal to the sum of (i) the Reference Rate, plus (ii)
                  the Applicable Margin.

                           (c) Any Advance not paid when due, whether at the
                  date scheduled therefor or earlier upon acceleration, shall
                  bear interest until paid in full (i) during the balance of any
                  Interest Period applicable to such Advance, at a rate per
                  annum equal to the sum of the rate applicable to such Advance
                  during such Interest Period plus 2.0%, and (ii) otherwise, at
                  a rate per annum equal to the sum of (A) the Reference Rate,
                  plus (B) the Applicable Margin for Reference Rate Advances,
                  plus (C) 2.0%.

                           (d) Interest shall be payable (i) with respect to
                  each Eurodollar Rate Advance having an Interest Period of
                  three months or less, on the last day of the Interest Period
                  applicable thereto; (ii) with respect to any Eurodollar Rate
                  Advance having an Interest Period greater than three months,
                  on the last day of the Interest Period applicable thereto and
                  on each day that would have been the last day of the Interest
                  Period for such Advance had successive Interest Periods of
                  three months duration been applicable to such Advance; (iii)
                  with respect to any Reference Rate Advance, on the fifteenth
                  (15) day of each month beginning January 15, 1996; (iv) with
                  respect to all Advances, upon any permitted prepayment (on the
                  amount prepaid); and (v) with respect to all Advances, on the
                  Termination Date; provided that interest under Section 3.3 (c)
                  shall be payable on demand.

                  3.4 OPTIONAL PREPAYMENTS. The Borrower may prepay Reference
         Rate Advances, in whole or in part, at any time, without premium or
         penalty except in the case of termination or cancellation of the Credit
         by the Borrower, in which event a credit termination fee shall be due
         and payable in accordance with Section 5.4. Except upon an acceleration
         following an Event of Default or upon termination of the Credit in
         whole, the Borrower may pay Eurodollar Rate Advances only on the last
         day of the Interest Period applicable thereto. Amounts paid (unless
         following an acceleration or upon termination of the Credit in whole)
         or prepaid on Advances under this Section 3.4 may be reborrowed upon
         the terms and subject to the conditions and limitations of the Credit
         Agreement.

                  3.5 INTEREST RATE NOT ASCERTAINABLE, ETC. If, on or prior to
         the date for determining the Adjusted Eurodollar Rate in respect of the
         Interest Period for any Eurodollar Rate Advance, the Lender determines
         (which determination shall be conclusive and binding, absent error)
         that:

                          (a) deposits in dollars (in the applicable amount)
                  are not being

                                       7

                  made available to the Lender in the relevant market for such
                  Interest Period, or

                           (b) the Adjusted Eurodollar Rate will not adequately
                  and fairly reflect the cost to the Lender of funding or
                  maintaining Eurodollar Rate Advances for such Interest Period,

         the Lender shall forthwith give notice to the Borrower of such
         determination, whereupon the obligation of the Lender to make or
         continue, or to convert any Advances to, Eurodollar Rate Advances, as
         the case may be, shall be suspended until the Lender notifies the
         Borrower that the circumstances giving rise to such suspension no
         longer exist. While any such suspension continues, all further Advances
         by the Lender shall be made as Reference Rate Advances. No such
         suspension shall affect the interest rate then in effect during the
         applicable Interest Period for any Eurodollar Rate Advance outstanding
         at the time such suspension is imposed.

                  3.6      INCREASED COST.  If any Regulatory Change:

                           (a) shall subject the Lender to any tax, duty or
                  other charge with respect to its Eurodollar Rate Advances, its
                  obligation to make Eurodollar Rate Advances or shall change
                  the basis of taxation of payment to the Lender of the
                  principal of or interest on Eurodollar Rate Advances or any
                  other amounts due under this Agreement in respect of
                  Eurodollar Rate Advances or its obligation to make Eurodollar
                  Rate Advances (except for changes in the rate of tax on the
                  overall net income of the Lender imposed by the jurisdiction
                  in which the Lender's principal office is located); or

                           (b) shall impose, modify or deem applicable any
                  reserve, special deposit, capital requirement or similar
                  requirement (including, without limitation, any such
                  requirement imposed by the Board, but excluding with respect
                  to any Eurodollar Rate Advance any such requirement to the
                  extent included in calculating the applicable Adjusted
                  Eurodollar Rate) against assets of, deposits with or for the
                  account of, or credit extended by, the Lender or shall impose
                  on the Lender or on the interbank Eurodollar market any other
                  condition affecting its Eurodollar Rate Advances or its
                  obligation to make Eurodollar Rate Advances;

         and the result of any of the foregoing is to increase the cost to the
         Lender of making or maintaining any Eurodollar Rate Advance, or to
         reduce the amount of any sum received or receivable by the Lender under
         this Agreement or under the Note, then, within 30 days after demand by
         the Lender, the Borrower shall pay to the Lender such additional amount
         or amounts as will compensate the Lender for such increased cost or
         reduction. The Lender will promptly notify the Borrower of any event of
         which it has knowledge, occurring after the date hereof, which will
         entitle the Lender to compensation pursuant to this Section. A
         certificate of the Lender claiming compensation under this Section,
         setting forth the additional amount or amounts to be paid to it
         hereunder and stating in reasonable detail the basis for the charge and
         the method of computation, shall be conclusive in the absence of error.
         In determining



                                       8

<PAGE>
<PAGE>


         such amount, the Lender may use any reasonable averaging and
         attribution methods. Failure on the part of the Lender to demand
         compensation for any increased costs or reduction in amounts received
         or receivable with respect to any Interest Period shall not constitute
         a waiver of the Lender's rights to demand compensation for any
         increased costs or reduction in amounts received or receivable in any
         subsequent Interest Period.

                  3.7 ILLEGALITY. If any Regulatory Change shall make it
         unlawful or impossible for the Lender to make, maintain or fund any
         Eurodollar Rate Advances, the Lender shall notify the Borrower,
         whereupon the obligation of the Lender to make or continue, or to
         convert any Advances to, Eurodollar Rate Advances shall be suspended
         until the Lender notifies the Borrower that the circumstances giving
         rise to such suspension no longer exist. If the Lender determines that
         it may not lawfully continue to maintain any Eurodollar Rate Advances
         to the end of the applicable Interest Periods, all of the affected
         Advances shall be automatically converted to Reference Rate Advances as
         of the date of the Lender's notice, and upon such conversion the
         Borrower shall indemnify the Lender in accordance with Section 3.8.

                  3.8 FUNDING LOSSES; EURODOLLAR RATE ADVANCES. The Borrower
         shall compensate the Lender, upon its written request, for all losses,
         expenses and liabilities (including any interest paid by the Lender to
         lenders of funds borrowed by it to make or carry Eurodollar Rate
         Advances to the extent not recovered by the Lender in connection with
         the re-employment of such funds and including loss of anticipated
         profits) which the Lender may sustain: (i) if for any reason, other
         than a default by the Lender, a funding of a Eurodollar Rate Advance
         does not occur on the date specified therefor in the Borrower's request
         or notice as to such Advance under Section 3.1 or 3.2, or (ii) if, for
         whatever reason (including, but not limited to, acceleration of the
         maturity of Advances following an Event of Default), any repayment of a
         Eurodollar Rate Advance, or a conversion pursuant to Section 3.7,
         occurs on any day other than the last day of the Interest Period
         applicable thereto. The Lender's request for compensation shall set
         forth the basis for the amount requested and shall be final, conclusive
         and binding, absent error.

                  3.9 DISCRETION OF LENDER AS TO MANNER OF FUNDING. The Lender
         shall be entitled to fund and maintain its funding of Eurodollar Rate
         Advances in any manner it may elect, it being understood, however, that
         for the purposes of this Agreement all determinations hereunder
         (including, but not limited to, determinations under Section 3.8, but
         excluding determinations that the Lender may elect to make from the
         Telerate System, Inc. screen) shall be made as if the Lender had
         actually funded and maintained each Eurodollar Rate Advance during the
         Interest Period for such Advance through the purchase of deposits
         having a maturity corresponding to the last day of the Interest Period
         and bearing an interest rate equal to the Eurodollar Rate for such
         Interest Period.

                  3.10 OVERDRAFT LOANS; OVER ADVANCES. Overdraft Loans and Over
         Advances shall bear interest at the rate(s) determined pursuant to
         Section 2.7 or Section 2.8 of the Credit Agreement, as applicable.

         provided, however, that no termination fee shall be due or payable for
         six (6) months after the Lender has demanded from the Borrower such
         amount or amounts as will compensate the Lender for increased capital
         requirements as set forth in Section 10.3 of the Credit Agreement.

         6. ELIGIBLE ACCOUNT RECEIVABLE REQUIREMENTS. The Account Receivable
