On October 10, 1996, the Company purchased substantially all of the assets of
Weldco Inc. (Weldco) pursuant to a Purchase and Sale Agreement (the Weldco
Purchase Agreement) for approximately $11.1 million. Approximately $7.9 million
of the purchase price was paid by promissory notes from the Company. In
conjunction with the Company's initial public offering, Weldco shareholders
converted a portion of the Company's promissory notes to shares of the Company's
common stock at the initial public offering price. The Company prepaid
$1,720,000 under the Company's promissory notes and issued 135,000 shares of
common stock to Weldco shareholders immediately prior to the closing of the
Offering in exchange for the cancellation of indebtedness in the amount of
$2,800,000. Additionally, certain Weldco shareholders purchased 100,000 shares
of common stock in the Offering. The Weldco Purchase Agreement further grants
Weldco shareholders the right to cause the Company to purchase the 235,000
shares of common stock issued to Weldco shareholders pursuant to the conversion
of indebtedness for a period of three years following the closing of the
Offering at the initial public offering price plus interest from the date of
issuance at the rate of 6.6% per annum. Accordingly, such shares will not be
classified as shareholders' equity. The Company's payment obligation is secured
by a letter of credit.

Prime rate was 8.5% and LIBOR was 5.6875% at September 30, 1997.

On October 4, 1996, the Company executed a three year revolving credit agreement
with Bank One for the purpose of refinancing the then existing revolving credit
agreement with NationsBank and to provide additional acquisition capital. This
agreement provided for a term note of $13,000,000 at a variable interest rate
based upon prime or LIBOR, depending on the Company's funded debt to EBITDA
ratio, payable monthly through September of 2003. The agreement also provided
for a revolving note with maximum borrowings (including letters of credit) of
$25,000,000 at a variable interest rate equal to that of the term note payable
monthly through September of 1999. A commitment fee of $32,500 was paid upon
acceptance of the agreement. These notes are secured by the Company's accounts
receivable, equipment, inventory, and general intangibles, and the proceeds
thereof. The agreement also contains various financial covenants including
minimum fixed charge coverage, maximum of funded debt to EBITDA, and minimum net
worth level.

On September 29, 1997 the Company entered into an amended and restated revolving
credit agreement with Bank One which increased the term note to $15,350,000 and
the maximum revolving note borrowings to $34,250,000. The maturity of the 
revolving note was also extended to October 2000. The Company is not required
to make principal payments on outstanding balances of the revolving loan as
long as certain covenants are satisfied. The Company pays a fee for the unused
portion of the revolving loan. The loan agreement for the credit facility
contains various financial covenants applicable to the Company, including
covenants requiring minimum fixed charge coverage, maximum funded debt to
EBITDA, and minimum net worth.

5. SUBSEQUENT EVENTS:

On October 31, 1997 the Company entered into an agreement for the purchase of
all of the stock of an industrial gas and welding distributor having
approximately $2 million in annualized sales. The Company expects this
transaction to close within 30 days and to be financed with borrowings under the
credit facility and notes with the Seller.

6. PRO FORMA INFORMATION (UNAUDITED):

The pro forma adjustments for income taxes included in the accompanying
condensed consolidated statement of operations for the three months ended
September 30, 1996 are based upon the statutory rates in effect for C
Corporations during the periods presented. Pro forma earnings per share were
calculated by dividing pro forma earnings by the weighted average shares
outstanding for the period. The weighted average number of shares outstanding
used to calculate the pro forma net income per share is based on the historical
weighted average number of shares outstanding using an offering price of $8 per
share.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
        FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with, and is qualified in
its entirety by, the Financial Statements and the Notes thereto.


OVERVIEW

The Company is a leading packager and distributor of industrial, medical and
specialty gases, welding equipment and supplies, and propane in ten states in
the mid-Atlantic and midwestern regions of the United States. The Company's net
sales have grown, primarily as a result of acquisitions, at a compound annual
rate of approximately 17% per year since the Company started business in 1958,
increasing from $190,000 in that year to $80.0 million for the last twelve
months. In fiscal 1997, gases accounted for approximately 42% of net sales,
welding equipment and supplies accounted for approximately 44% of net sales, and
cylinder and tank rental accounted for approximately 14% of net sales.

The Company believes it has been successful in executing its strategy of growth
through acquisitions, having completed 28 acquisitions since 1990. Some
acquisitions have had, and the Company expects some future acquisitions may
have, a dilutive effect upon the Company's income from operations and net income
before tax for a short period following consummation. This temporary dilution
occurs because some of the benefits of acquisitions, such as leveraging of
operating and administrative expenses, improved product gross margins and real
sales growth, occur over a period ranging from two to eight quarters, depending
upon the complexity of integrating each acquisition into the Company's existing
operations. The consideration for most acquisitions includes a combination of a
cash payment at closing, seller financing and payments under covenants not to
compete and consulting agreements. In most cases, operating cash flow of an
acquired business is positive in a relatively short period of time. For many
acquisitions, the Company believes that projections of future cash flows justify
payment of amounts in excess of the book or market value of the assets acquired,
resulting in goodwill being recorded.

The Company's results are subject to moderate seasonality, primarily due to
fluctuations in the demand for propane, which is highest during winter months
falling in the Company's second and third fiscal quarters.

Operating and administrative expenses are comprised primarily of salaries,
benefits, transportation equipment operating costs, facility lease expenses and
general office expenses. These expenses are generally fixed on a quarter-
to-quarter basis. The Company believes that changes in these expenses as a
percentage of sales should be evaluated over the long term rather than on a
quarter-to-quarter basis due to the moderate seasonality of sales mentioned
above and the generally fixed nature of these expenses.

Historically, the Company's gross profit margins as a percentage of sales have
been higher on the sale of gases than on the sale of welding equipment and
supplies ("hard goods"). As a result of recent acquisitions of some distributors
with a higher proportion of hard goods to gas sales, the Company's average gross
profit as a percentage of sales has decreased in comparison to prior years.
Future acquisitions may affect this pattern depending upon the product mix of
the acquired businesses.

Until April 10, 1997, the Company was treated as an S Corporation for federal
and state income tax purposes. As a result, the Company was not subject to
federal and state income taxes. The Company terminated its S Corporation
election in connection with its initial public offering of stock and become a C
Corporation. As a result of termination of the S Corporation election, the
Company recognized $3.9 million of deferred income taxes in the fourth quarter
of fiscal year 1997.

RESULTS OF OPERATIONS

COMPARISON OF THREE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996

Net sales increased 42.1%, or $6.1 million, to $20.6 million from $14.5 million
for the three months ended September 30, 1997 and 1996, respectively.
Acquisitions made during the preceding twelve months contributed $5.1 million of
the increase in net sales, while same store growth contributed $1.0 million of
the increase. Same store sales increased 6.6% versus the same quarter last year.
Increased propane sales represented 2.5% growth and all other products reflected
4.1% growth over the same quarter last year on a same store basis. Gases and
cylinder revenue represented 52.8% of net sales for the three months ended
September 30, 1997, with hard goods representing 47.2%. In comparison, net sales
for the three months ended September 30, 1996 reflected gases and cylinder
revenue as 58.0% and hard goods as 42.0%. This change in sales mix reflects the
effect of acquisitions made during the preceding twelve months.

Gross profit, which excludes depreciation and amortization, increased 36.2%, or
$3.0 million, to $11.1 million from $8.1 million for the three months ended
September 30, 1997 and 1996, respectively. Acquisitions made during the
preceding twelve months contributed $2.6 million of the increase in gross
profit, while the base business contributed $0.4 million of the increase. Gross
profit as a percentage of net sales was 54.1% for the three months ended
September 30, 1997, compared to 56.4% for the three months ended September 30,
1996. This change reflected an increase in the proportion of hard good sales,
which have a lower gross profit margin as a percentage of net sales than gases.

Operating and administrative expenses increased 28.3%, or $1.6 million, to $7.4
million from $5.7 million for the three months ended September 30, 1997 and
1996, respectively. Of this increase, $1.4 million was related to acquired
businesses and the remaining $0.2 million reflected increases on a same store
basis. Operating and administrative expenses as a percentage of sales decreased
to 35.7% for the three months ended September 30, 1997, as compared to 39.6% for
the same quarter in 1996, reflecting the addition of operating expenses related
to acquired businesses as a percentage of sales at a rate lower than the Company
average before the acquisitions were made.

Depreciation and amortization expense increased $0.5 million for the three
months ended September 30, 1997 compared to the same period in 1996, primarily
as a result of acquisitions made during the last twelve months.

Interest expense increased $0.2 million for the quarter, reflecting the
financing of acquisitions made during the last twelve months, partially reduced
by lower interest rates.

Net earnings increased 88.8%, or $0.4 million, to $0.8 million from pro forma
net earnings $0.4 million for the three months ended September 30, 1997 and
1996, respectively.

LIQUIDITY AND CAPITAL RESOURCES

Historically, the Company has financed its operations, capital expenditures and
debt service with funds provided from operating activities. Acquisitions have
been financed by a combination of seller financing, bank borrowings and funds
generated from operations.

At September 30, 1997, the Company had working capital of approximately $7.8
million. Funds provided by operations for the three months ended September 30,
1997 were approximately $2.1 million. Funds used for investing activities were
approximately $9.9 million for the three months ended September 30, 1997,
consisting primarily of capital spending and financing for two acquisitions.
Sources of funds from financing activities for the three months ended September
30, 1997 were approximately $7.0 million from net borrowings. The company's cash
balance decreased $0.8 million during the quarter as $0.7 million in voluntary
debt reduction was made.

On September 29, 1997, the Company entered into an amended and restated
revolving credit agreement totaling $49.6 million, consisting of a $15.4 million
term loan, which matures in six years and is amortized in equal monthly
payments, and a $34.2 million revolving loan with a $15.0 million sublimit for
letters of credit, which matures in October 2000. The revolving loan is used
primarily to fund acquisitions. The Company is not required to make principal
payments on outstanding balances of the revolving loan as long as certain
covenants are satisfied. Interest is charged on both the term loan and the
revolving loan at either the lender's prime rate or various LIBOR rates, at the
Company's discretion, plus an applicable spread. The weighted average interest
rate for substantially all of the borrowings under the credit facility was 7.4%
as of September 30, 1997. The Company pays a fee for the unused portion of the
revolving loan. As of September 30, 1997, availability under the revolving loan
was approximately $13.2 million, with outstanding borrowings of approximately
$13.3 million and outstanding letters of credit of approximately $7.7 million.
The credit facility is secured by all of the Company's assets.

The loan agreement for the credit facility contains various financial covenants
applicable to the Company, including covenants requiring minimum fixed charge
coverage, maximum funded debt to EBITDA, and minimum net worth. The Company is
in compliance with these covenants and believes that it will continue to be in
compliance through at least the next twelve months.

The Company is obligated under various promissory notes related to the financing
of acquisitions that have various rates of interest, ranging from 3.0% to 10.0%
per annum, and maturities through 2010. The outstanding balance of these notes
as of September 30, 1997 was $14.6 million. Some of these notes are secured by
assets related to the applicable acquisition, some are unsecured, and some are
backed by bank letters of credit issued under the Company's credit facility.

FLUCTUATIONS IN QUARTERLY RESULTS

The Company generally has experienced higher sales activity during its second
and third quarters as a result of seasonal sales of propane, with corresponding
lower sales for the first and fourth quarters. As a result, income from
operations and net income typically are higher for the second and third quarters
than for the first and fourth quarters of the fiscal year.

INFLATION

The impact of inflation on the Company's operating results has been moderate in
recent years, reflecting generally low rates of inflation in the economy and the
Company's historical ability to pass purchase price increases to its customers
in the form of sales price increases. While inflation has not had, and the
Company does not expect that it will have, a material impact upon operating
results, there is no assurance that the Company's business will not be affected
by inflation in the future.


SUBSEQUENT EVENTS

On October 31, 1997 the Company entered into an agreement for the purchase of
all of the stock of an industrial gas and welding distributor having
approximately $2 million in annualized sales. The Company expects this
transaction to close within 30 days and to be financed with borrowings under the
credit facility and notes with the Seller.

     other capacity.

     "PLAN" means an employee pension benefit plan as defined in ERISA.

     "PREPAYMENT PREMIUM" means the excess, if any, as determined by the Bank
     of: (i) the present value at the time of prepayment of the interest
     payments which would have been payable on account of an amount prepaid
     from the date of prepayment until the end of the period during which
     interest would have accrued at a LIBOR-based Rate but for prepayment over
     (ii) the present value at the time of prepayment of interest payments
     calculated at the rate (the "REINVESTMENT RATE") which the Bank then
     estimates it would receive upon reinvesting the principal amount of the
     prepayment in an obligation which presents a credit risk substantially
     similar (as determined in accordance with the commercial credit rating
     system then used by the Bank) to that which is then presented by the Loan

     actually charged by the Bank on any loan or class of loans.

     Applicable Unused Commitment Fee, the Ratio of Total Funded Debt to EBITDA
     shall be determined on the Closing Date on the basis of the consolidated
     Financial Statements of the Credit Parties and their respective
     Subsidiaries provided to the Bank prior to the Closing Date for the
     preceding twelve (12) calendar month period ending June 30, 1997, and

               ADJUSTMENT"), with prospective effect until the next adjustment
               date. Quarterly

               Adjustments shall be made on the first interest payment date
               which follows receipt by the Bank of the consolidated Financial
               Statements for the last month of the first fiscal quarter of the
               Company ending after the Closing Date, and thereafter on the
               first interest payment date which follows receipt by the Bank of
               the consolidated Financial Statements upon which such adjustment
               is based (a "QUARTERLY ADJUSTMENT DATE"), but no Quarterly
               Adjustment shall be effective as to any LIBOR-based Rate elected
               prior to the Quarterly Adjustment Date until the expiration of
               the period of time for which such LIBOR-based Rate shall have
               been elected by the Company.

                    (ii) NEW ACQUISITION ADJUSTMENTS. For purposes of
               determining the Applicable Spread and the Applicable Unused
               Commitment Fee, the Ratio of Total Funded Debt to EBITDA shall
               be redetermined and adjusted as necessary on each New
               Acquisition Closing Date on the basis of the consolidated
               Financial Statements of the Credit Parties and their respective
               Subsidiaries for the most recent twelve (12) calendar month
               period that precedes the New Acquisition Closing Date provided
               to the Bank pursuant to the requirements of subsection 5.01(b)
               of this Agreement (a "NEW ACQUISITION ADJUSTMENT"), with
               prospective effect until the next adjustment date, but no New
               Acquisition Adjustment shall be effective as to any LIBOR-based
               Rate elected prior to the New Acquisition Date until the
               expiration of the period of time for which such LIBOR-based Rate
               shall have been elected by the Company.

     Notwithstanding the foregoing, in the event that the Credit Parties fail
     to deliver when due the Financial Statements and compliance certificates
     required under subsection 5.01(b) of this Agreement for any month which
     ends a fiscal quarter of the Company and fail to cure such default within
     ten (10) days after notice of such default by the Bank, then the
     Applicable Unused Commitment Fee Percentage and the Applicable Spread
     shall be adjusted (without prior notice by the Bank to the Company) to the
     largest number shown in the table applicable to such definition from such
     due date until the first interest payment date which follows delivery to
     the Bank of such Financial Statements. It is noted that the tables
     defining Applicable Unused Commitment Fee Percentage and the Applicable
     Spread provide for a Ratio of Total Funded Debt to EBITDA greater than
     that which may be permissible under the terms of subsection 5.01(g) of
     this Agreement. For the avoidance of doubt, it is agreed that it is the
     intent of the parties that the Bank shall be free to exercise all remedies
     otherwise provided for in this Agreement in the event of the violation by
     the Credit Parties as stated in subsection 5.01(g) this Agreement,
     notwithstanding the determination of the Applicable Unused Commitment Fee
     Percentage and the Applicable Spread in accordance with and by reference
     to this definition.

     SECTION 2.01. GENERAL STATEMENT. Subject to and in accordance with the
terms of this Agreement, and in reliance upon the representations, warranties,
covenants and agreements of the Company made in this Agreement and the other
Loan Documents, the Bank will make the Loans and issue the Letters of Credit
described in this Article II.

     SECTION 2.02. THE REVOLVING LOAN.

     (a) THE COMMITMENT -- USE OF PROCEEDS. The Bank agrees, subject to the
terms and conditions of this Agreement, to make Advances to the Company on a
revolving basis (the "REVOLVING LOAN") from time to time from and after the
Closing Date until the Revolving Loan Maturity Date, in an amount not exceeding
in the aggregate at any time outstanding the Maximum Availability. Proceeds of
the Revolving Loan may be used by the Company only to fund working capital
requirements, Capital Expenditures and New Acquisitions and to refinance
existing Debt of the Company.

     The Revolving Loan under this Agreement is a continuation, on amended
term, of the "Revolving Loan" extended to the Company by the Bank under the
Original Agreement (the "PRIOR REVOLVING LOAN") and the Company affirms,
acknowledges and agrees that the principal balance of the Revolving Loan as of
the Closing Date is $13,853,675.72, being the unpaid principal amount of the
Prior Revolving Loan immediately prior to the execution of this Agreement
($9,937,291.78) after taking into account the $4,052,380.90 in principal
being applied against the Revolving Loan with

                                       13

<PAGE>   14



proceeds of the Term Loan concurrently with the execution of this Agreement
pursuant to Section 2.04 of this Agreement.

     (b) METHOD OF BORROWING. The obligation of the Company to repay the
Revolving Loan shall be evidenced by a promissory note executed by the Company
to the Bank in the form of EXHIBIT D attached hereto (as the same may be
amended, modified, extended, renewed, supplemented, replaced and/or restated
from time to time and at any time, the "REVOLVING NOTE"). So long as no Event
of Default or Unmatured Event of Default shall have occurred and be continuing
and until the Revolving Loan Maturity Date, the Company may borrow, repay
(subject to the requirements of Section 2.06 of this Agreement) under the
Revolving Note on any Banking Day, provided that Company shall not be entitled
to receive and the Bank shall not be obligated to make any Advance: (i) at any
time an Event of Default or an Unmatured Event of Default has occurred or is
continuing; (ii) if the amount of such Advance would exceed the Remaining
Availability; or (iii) if after making such Advance the principal balance of
the Revolving Loan would exceed the Maximum Availability. Each Advance under
the Revolving Loan shall be conditioned upon receipt by the Bank from the
Company of an Application for Revolving Loan Advance and an Officer's
Certificate, provided that the Bank may, at its discretion, make a disbursement
upon the oral request of the Company made by an Authorized Officer, or upon a
request transmitted to the Bank by telecopy or by any other form of written
electronic communication (all such requests for Advances being hereafter
referred to as "INFORMAL REQUESTS"). In so doing, the Bank may rely on any
informal request which shall have been received by it in good faith from a
Person reasonably believed to be an Authorized Officer. Each informal request
shall be promptly confirmed by a duly executed Application for a Revolving Loan
Advance and Officer's Certificate if the Bank so requires and shall in and of
itself constitute the representation of the Company that no Event of Default or
Unmatured Event of Default has occurred and is continuing or would result from
the making of the requested Advance, that the requested Advance would not
exceed the Remaining Availability, and that the making of the requested Advance
would not cause the principal balance of the Revolving Loan to exceed the
Maximum Availability. All borrowings and reborrowings and all repayments shall
be in amounts of not less than Fifty Thousand Dollars ($50,000), except for
repayment of the entire principal balance of the Revolving Loan and except for
special prepayments of principal required under the terms of Section 2.06 of
this Agreement. Upon receipt of an Application for a Revolving Loan Advance, or
at the Bank's discretion upon receipt of an informal request for an Advance and
upon compliance with any other conditions of lending stated in Section 6.01 of
this Agreement applicable to the Revolving Loan, the Bank shall disburse the
amount of the requested Advance to the Company. All Advances by the Bank and
payments by the Company shall be recorded by the Bank on its books and records,
and the principal amount outstanding from time to time, plus interest payable
thereon, shall be determined by reference to the books and records of the Bank.
The Bank's books and records shall be presumed PRIMA FACIE to be correct as to
such matters.

     (c) INTEREST ON THE REVOLVING LOAN. The principal amount of the Revolving
Loan outstanding from time to time shall bear interest until the Revolving Note
Maturity Date at a rate per annum equal to the Prime Rate plus the Applicable
Spread; PROVIDED THAT, at the option of the Company, exercised from time to
time as provided in subsection 2.05(a) of this Agreement, interest may accrue
prior to the Revolving Loan Maturity Date on any Advance or on the entire
outstanding balance of the Revolving Loan as to which no LIBOR-based Rate
previously elected remains in effect, at a rate per annum equal to a
LIBOR-based Rate for a period of one month, two months, three months or six
months, plus the Applicable Spread. Notwithstanding the foregoing, the Company
will not be permitted to elect any LIBOR-based Rate for a period extending
beyond the Scheduled Revolving Loan Maturity Date.

                                       14

<PAGE>   15



After the Revolving Loan Maturity Date, and until paid in full, the principal
amount of the Revolving Loan shall bear interest at a per annum rate equal to
the Prime Rate plus Two Percent (2%). Accrued interest shall be due and payable
monthly on the last Banking Day of October, 1997, and on the last Banking Day
of each successive calendar month thereafter until the Revolving Loan Maturity
Date, at which time the entire unpaid principal balance of the Revolving Loan
and all unpaid, accrued interest thereon, shall be due and payable in full
without demand. After the Revolving Loan Maturity Date, interest shall be
payable as accrued and without demand.

     (d) EXTENSIONS OF SCHEDULED REVOLVING LOAN MATURITY DATE. The Bank may,
upon the request of the Company, but at the Bank's sole discretion, extend the
Scheduled Revolving Loan Maturity Date from time to time to such date or dates
as the Bank may elect by notice in writing to the Company, and upon any such
extension, the date to which the Scheduled Revolving Loan Maturity Date is then
extended will become the "Scheduled Revolving Loan Maturity Date" for purposes
of this Agreement. The Bank agrees to respond within forty-five (45) days to a
written request for an extension of the Scheduled Revolving Loan Maturity Date
made by the Company in accordance with Section 8.02 of this Agreement and made
within one hundred eighty (180) days prior to the Scheduled Revolving Loan
Maturity Date, provided that any failure by the Bank to respond within such
period shall be deemed to be a denial of such request unless otherwise agreed
to in writing by the Bank.

     (e) FACILITY FEE. In addition to interest accruing on the Revolving Loan,
the Company shall pay to the Bank a facility fee for each partial or full
calendar quarter from and after the Closing Date until the Revolving Loan
Maturity Date equal to the Applicable Unused Commitment Fee Percentage per
annum on the daily average "Unused Revolving Loan Commitment" (as hereinafter
defined). As used herein, the term "UNUSED REVOLVING LOAN COMMITMENT" means, as
of the time of any determination thereof is to be made, the positive excess, if
any, which results by subtracting from the Maximum Availability the sum of the
then outstanding principal amount of the Revolving Loan plus the then existing
aggregate Letter of Credit Exposure. Facility fees for each calendar quarter
shall be due and payable within ten (10) days following the Bank's submission
of a statement of the amount due. Such fees may be debited by the Bank when due
to any demand deposit account of the Company carried with the Bank without
further authority.

     SECTION 2.03. STANDBY LETTERS OF CREDIT.

     (a) STANDBY LETTERS OF CREDIT -- GENERAL. At any time that the Company is
entitled to an Advance under the Revolving Loan, the Bank agrees, subject to
the terms and conditions of this Agreement, to issue upon the application of
the Company and for the account of the Company a standby letter of credit for
the purpose of supporting payment of all or any part of the Acquisition Seller
Debt or for any other general business purpose other than Credit Enhancement
(each a "LETTER OF CREDIT"), PROVIDED THAT:

          (1) The aggregate Letter of Credit Exposure shall not at any time
     exceed Fifteen Million Dollars ($15,000,000);

          (2) The Company shall not request and the Bank shall have no
     obligation to issue any Letter of Credit: (i) at any time any Event of
     Default or Unmatured Event Default shall have occurred and be continuing;
     (ii) at any time after the Revolving Loan Maturity Date; (iii) if, after
     giving effect to such issuance, the aggregate Letter of Credit Exposure
     would exceed

                                       15

<PAGE>   16



     Fifteen Million Dollars ($15,000,000); (iv) if the face amount of such
     Letter of Credit would exceed the Remaining Availability; or (v) for any
     purpose than to secure payment of all or any part of the Acquisition
     Seller Debt;

          (3) The Bank in no event shall be obligated to issue any Letter of
     Credit: (i) having an expiration date later than seven (7) years and
     thirty (30) days from the date of issuance; or (ii) if the issuance of
     such Letter of Credit on the terms requested would be contrary to, or in
     violation of the policies of the Bank or any requirement of applicable
     law;

          (4) The form of the requested Letter of Credit shall be satisfactory
     to the Bank in the reasonable exercise of the Bank's discretion; and

          (5) The Bank shall have received from the Company an application and
     reimbursement agreement for the Letter of Credit in form and substance
     satisfactory to the Bank in all respects (as the same may be amended,
     modified, extended, renewed, supplemented, replaced and/or restated from
     time to time and at any time, "REIMBURSEMENT AGREEMENT"), duly executed by
     an Authorized officer.

     (b) LETTER OF CREDIT PROCEDURES. Whenever the Company desires the issuance
of a Letter of Credit, it shall deliver to the Bank not later than 11:30 a.m.
(Dallas, Texas time) at least three Banking Days (or such shorter period as may
be agreed to by the Bank in any particular instance) in advance of the proposed
date of issuance a Reimbursement Agreement duly executed by an Authorized
Officer. Each Reimbursement Agreement shall include a precise description of
the documents and the verbatim text of any certificate to be presented by the
proposed beneficiary with, or as a part of any Draft; provided that the Bank,
in its sole judgment, may require changes in the description of any such
documents and the text of such certificates; and provided further that, at the
discretion of the Bank, each Letter of Credit shall provide that payment
against a conforming Draft is not required to be made thereunder prior to the
close of business on the third Banking Day following presentment of such Draft.

     (c) DRAWS UNDER LETTERS OF CREDIT. Upon presentation of a Draft under any
Letter of Credit by the beneficiary thereof, the Bank shall notify the Company
of the receipt thereof ("Draft Notice") not later than one Banking Day prior to
the date on which the Bank intends to honor such Draft. The Draft Notice may be
given by telephone or telecopy. Failure to give the Draft Notice or to give the
Draft Notice in a timely manner shall not in any way affect or limit the
payment obligation of the Company hereunder. Upon receipt of the Draft Notice,
the Company shall make or cause to be made an irrevocable deposit with the Bank
not later than 1:00 p.m., Dallas, Texas time, one (1) Banking Day prior to the
day on which the Draft is to be honored, in an amount equal to the full amount
which is to be paid under such Draft, in good and collected funds (the
"REIMBURSEMENT AMOUNT"), specifying that it is depositing such money for the
sole purpose of funding the payment of such Draft.

     In determining whether to honor any Draft, the Bank shall be responsible
only to determine that the documents and certificates required to be delivered
with such Draft under the appropriate Letter of Credit have been delivered and
that on their faces they are in substantial compliance with the requirements of
that Letter of Credit. In the event of any conflict between the terms of any
Reimbursement Agreement and the terms of this Agreement, the terms of this
Agreement shall control; and the terms of a Reimbursement Agreement shall not
be deemed to be in conflict with the terms of this Agreement solely by reason
of the fact that it addresses one or more subject matters that are

                                       16

<PAGE>   17



addressed by this Agreement and contains provisions that are different from
those set forth in this Agreement.

     (d) REIMBURSEMENT OBLIGATIONS OF THE COMPANY. The Company hereby agrees to
reimburse the Bank, on demand, the amount paid by the Bank to settle its
obligations in respect of each Draft under each Letter of Credit (whether such
amount is paid by virtue of the Bank's honor of any Draft or otherwise) to the
extent that a Reimbursement Amount is not available to the Bank for that
purpose, which reimbursement obligation shall be immediate and automatic,
without the necessity of any further act or the execution of any additional
document, instrument, or agreement. Any Reimbursement Amount that is not paid
in full when due shall be deemed to be and shall constitute a demand loan made
to the Company by the Bank on such due date in the principal amount of the
unpaid Reimbursement Amount (each such loan being referred to herein as a
"LETTER OF CREDIT LOAN", and collectively as "LETTER OF CREDIT LOANS"), which
Letter of Credit Loans shall bear interest, until paid in full, at a per annum
rate equal to the Prime Rate plus Two Percent (2%). A demand for payment of
each Reimbursement Amount and Letter of Credit Loan shall be deemed to have
been made by the Bank on the date of the corresponding payment by the Bank to
settle its obligations under a Draft. Nothing herein is intended to preclude
the Company from requesting an Advance to the extent available under the
Revolving Loan to pay any Reimbursement Amount.

     The obligation of the Company to reimburse the Bank in respect of drawings
made under the Letters of Credit shall be unconditional and irrevocable and
shall be paid strictly in accordance with the terms of this Agreement and the
applicable Reimbursement Agreement (if and to extent the terms of such
Reimbursement Agreement do not conflict with this Agreement) under all
circumstances, and notwithstanding any of the following circumstances:

     (1)  any lack of validity or enforceability of any Letter of Credit;

     (2)  the existence of any claim, set-off, defense or other right which the
          Company may have at any time against a beneficiary or any transferee
          of any Letter of Credit or (or any Persons for whom any such
          transferee may be acting), or any other Person, whether in connection
          with this Agreement, the transactions contemplated herein or any
          unrelated transaction (including any underlying transaction between
          the Company and the beneficiary of any Letter of Credit;

     (3)  any draft, demand, certificate or any other document presented under
          any Letter of Credit proving to be forged, fraudulent, invalid or
          insufficient in any respect or any statement therein being untrue or
          inaccurate in any respect;

     (4)  payment by the Bank under any Letter of Credit against presentation
          of a demand, draft or certificate or other document which does not
          comply with the terms of such Letter of Credit;

     (5)  any other circumstance or happening whatsoever which is similar to
          any of the foregoing; or

     (6)  the fact that an Event of Default or Unmatured Event of Default shall
          have occurred and be continuing;

                                       17

PROVIDED HOWEVER, that the Company shall not be obligated to reimburse the Bank
for any wrongful payment or disbursement made or to be made by the Bank under
any Letter of Credit as a result of acts or omissions constituting gross
negligence or willful misconduct on the part of the Bank. Payment of a Draft
that does not comply with the terms of the Letter of Credit against which it is
presented shall not in any event be deemed to be wrongful or an act or omission
constituting gross negligence or willful misconduct on the part of the Bank if
such payment is made at the specific written request of the Company in which
the Company waives the non-compliance of the Draft.

     Upon a written request by the Company made in accordance with the terms of
Section 8.02 of this Agreement, the Bank will undertake to provide to the
Company copies of all instruments and documents constituting a Draft with the
Draft Notice, and in the event the Company has any knowledge (however obtained)
of any claim of non-compliance with the Company's instructions or with the
terms of the Letter of Credit, or of discrepancies or other irregularities, the
Company shall immediately notify the Bank thereof in writing, and the Company
shall be deemed to have waived any such claim or defense against the Bank
related thereto or arising therefrom unless such notice is given. The Company
shall be deemed to have knowledge of any such claim that is apparent on the
face of copies of instruments and documents constituting a Draft that are
provided to the Company pursuant to the preceding sentence.

     Unless specified to the contrary in the Reimbursement Agreement for a
Letter of Credit, or any amendment to a Letter of Credit, the Company agrees
that the Bank and its correspondents may receive and accept any Draft drawn or
presented under such Letter of Credit or other document otherwise in order,
issued or purportedly issued by an agent, executor, trustee in bankruptcy,
receiver or other representative of the party who is authorized under such
Letter of Credit to issue such Draft or other document, as complying with the
terms of such Letter of Credit.

     INDEMNITY. The Company agrees to protect, indemnify and save the Bank
harmless from and against any and all claims, demands, liabilities, damages,
losses, costs, charges and expenses (including reasonable attorneys' fees and
allocated costs of internal counsel) which the Bank may incur or be subject to
as a consequence, direct or indirect, of (a) the issuance of the Letters of
Credit, other than as a result of the negligence or willful misconduct of the
Bank, as determined by a court of competent jurisdiction, or (b) the failure of
the Bank to honor a drawing under any Letter of Credit as a result of any act
or omission, whether rightful or wrongful, of any present or future DE JURE or
DE FACTO government or governmental authority (all such acts or omissions
herein called "GOVERNMENT ACTS").

     As between the Company, on the one hand, and the Bank, on the other, the
Company assume all risks of the acts and omissions of, or misuse of the Letters
of Credit by the respective beneficiaries of such Letters of Credit. In
furtherance and not in limitation of the foregoing, the Bank shall not be
responsible and shall have no liability (a) for the form, validity,
sufficiency, accuracy, genuineness or legal effect of any document submitted by
any party in connection with the application for and issuance of such Letters
of Credit, even if it should in fact prove to be in any or all respects
invalid, insufficient, inaccurate, fraudulent or forged; (b) for the validity
or sufficiency of any instrument transferring or assigning or purporting to
transfer or assign any such Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason; (c) for failure of the beneficiary of
any such Letter of Credit to comply fully with the terms and conditions of the
agreement pursuant to which the Letter of Credit was procured and pursuant to
which the beneficiary is entitled to draw upon such Letter of Credit; (d) for
errors, omissions, interruptions or delays in transmission or delivery of any
messages, by mail, cable, telegraph, telex or

                                       18

<PAGE>   19



otherwise, whether or not they be in cipher; (e) for errors in interpretation
of technical terms; (f) for any loss or delay in the transmission or otherwise
of any document required in order to make a Draft under any such Letter of
Credit or of the proceeds thereof; (g) for the misapplication by the
beneficiary of any such Letter of Credit of the proceeds of any Draft under
such Letter of Credit; (h) for any consequences arising from causes beyond the
control of the Bank, including, without limitation, any Government Acts; and
(i) for any action taken or omitted by the Bank under or in connection with the
Letters of Credit, if taken or omitted in good faith. None of the above shall
affect, impair, or prevent the vesting of any of the Bank's rights or powers
hereunder.

     Following the occurrence of an Event of Default or an Unmatured Event of
Default which is continuing, the Company agrees that any action taken by the
Bank, if taken in good faith, under or in connection with any of the Letters of
Credit, Reimbursement Agreements and Drafts, shall be binding on the Company
and shall not subject the Bank to any resulting liability to the Company. In
furtherance thereof, the Bank shall have the full right and authority,
following an Event of Default or Unmatured Event of Default which is
continuing, to (i) clear and resolve any questions of non-compliance of
documents, (ii) to give any instructions as to acceptance or rejection of any
documents or goods, and (iii) to grant any extensions of the maturity of, time
of payment for, or time of presentation of, any drafts, acceptances, or
documents.

     (f) LETTER OF CREDIT FEES. The Company covenants and agrees to pay to the
Bank, on the date each Letter of Credit is issued, and on each anniversary of
the issue date for as long as the Letter of Credit is outstanding, a commission
equal to the "Applicable LOC Fee Percentage" (as hereinafter defined) times the
maximum amount available to be drawn under the Letter of Credit as of the date
such commission is due. As used herein, the term "APPLICABLE LOC FEE
PERCENTAGE" means, with respect to any Letter of Credit (i) One-Half Percent
(0.5%), if the reimbursement obligation of the Company to the Bank under the
Reimbursement Agreement and this Agreement for such Letter of Credit is fully
secured by Cash Collateral, and (ii) Three-Quarters Percent (0.75%), if the
reimbursement obligation of the Company to the Bank under the Reimbursement
Agreement and this Agreement for such Letter of Credit is not fully secured by
Cash Collateral. The commission shall be deemed fully earned and nonrefundable
when due. The Company shall pay the Bank's standard transaction fees with
respect to any transactions occurring on account of any Letter of Credit.
Transaction fees shall be payable upon completion of the transaction as to
which they are charged. All such commissions and fees may be debited by the
Bank to any deposit account of the Company carried with the Bank without
further authority, and in any event, shall be paid by the Company within ten
(10) days following billing.

     SECTION 2.04 THE TERM LOAN.

     (a) THE TERM LOAN -- GENERAL. The Bank agrees, subject to the terms and
conditions of this Agreement, to loan to the Company the principal amount of
Fifteen Million Three Hundred Fifty Thousand Dollars ($15,350,000.00) for the
term period beginning on the Closing Date and ending on the Term Loan Maturity
Date (the "TERM LOAN").

     The Term Loan under this Agreement is a continuation, on amended terms, of
the "Term Loan" extended to the Company by the Bank under the Original
Agreement (the "PRIOR TERM LOAN") and the Company affirms, acknowledges and
agrees that the principal balance of the Term Loan as of the Closing Date is
$15,350,000.00, being the unpaid principal amount of the Prior Term Loan
immediately prior to the execution of this Agreement ($11,297,619.10) plus a
supplemental principal advance of

                                       19

<PAGE>   20



$4,052,380.90 being made under the Term Loan and applied against the
outstanding principal balance of the Revolving Loan concurrently with the
execution of this Agreement.

     (b) THE TERM NOTE. The obligation of the Company to repay the Term Loan
shall be evidenced by a promissory note executed by the Company to the Bank in
the form of EXHIBIT E attached hereto (as the same may be amended, modified,
extended, renewed, supplemented, replaced and/or restated from time to time and
at any time, the "TERM NOTE"). The principal of the Term Loan shall be
repayable in equal monthly installments of $213,195.00 each, which monthly
installments shall be due and payable on the last Banking Day of October, 1997,
and on the last Banking Day of each successive calendar month thereafter until
the Term Loan Maturity Date, at which time the entire principal balance of the
Term Loan and all unpaid, accrued interest thereon, shall be due and payable in
full without demand. Subject to the contemporaneous payment of any Prepayment
Premium which would become due on account of any proposed prepayment, the
principal of the Term Loan may be prepaid at any time in whole or in part,
provided that any partial prepayment shall be in an amount which is an integral
multiple of Fifty Thousand Dollars ($50,000) and provided further that all
partial prepayments shall be applied to the latest maturing installments of
principal payable under the Term Loan in inverse order of maturity.

     (c) INTEREST ON THE TERM LOAN. The principal balance of the Term Loan
outstanding from time to time shall bear interest from the Closing Date until
the Term Loan Maturity Date at a rate per annum equal to the Prime Rate plus
the Applicable Spread, PROVIDED THAT, at the option of the Company exercised
from time to time as provided in subsection 2.05(a) of this Agreement, interest
may accrue prior to the Term Loan Maturity Date on the entire outstanding
balance of the Term Loan or on any portion thereof as to which no LIBOR-based
Rate previously selected remains in effect at a rate per annum equal to a
LIBOR-based Rate for a period of one month, two months, three months or six
months, plus the Applicable Spread. The Company will not be permitted to elect
any LIBOR-based Rate for a period extending beyond the Scheduled Term Loan
Maturity Date. After the Term Loan Maturity Date, interest will accrue on the
Term Loan at a rate per annum equal to the Prime Rate plus Two Percent (2%).
Prior to the Term Loan Maturity Date, interest shall be due and payable on the
last Banking Day of each month in addition to the installments of principal due
on such dates. After the Term Loan Maturity Date, interest shall be payable as
accrued and without demand.

     (d) USE OF PROCEEDS OF THE TERM LOAN. The proceeds of the Term Loan shall
be used in their entirety to refinance existing Debt of the Company.

     SECTION 2.05. PROVISIONS APPLICABLE TO BOTH OF THE LOANS. The following
provisions are applicable to both of the Loans:

     (a) PROCEDURES FOR ELECTING LIBOR-BASED RATES -- CERTAIN EFFECTS OF
ELECTION. LIBOR-based Rates may be elected only in accordance with the
following procedures, shall be subject to the following conditions, and the
election of a LIBOR-based Rate shall have the following consequences in
addition to other consequences stated in this Agreement:

          (1) The LIBOR-based Rate may be elected only for Loans or portions of
     Loans in a minimum amount of $1,000,000.00. No more than five (5)
     LIBOR-based Rate elections may be in effect under a Loan at any one time.


                                       20

<PAGE>   21



          (2) No LIBOR-based Rate may be elected at any time that an Event of
     Default or Unmatured Event of Default has occurred and is continuing.

          (3) Voluntary prepayment prior to scheduled maturity of all or any
     portion of a Loan on which interest is accruing at a LIBOR-based Rate
     shall be subject to contemporaneous payment of the Prepayment Premium if,
     at the time of prepayment, the Reinvestment Rate is less than the
     LIBOR-based Rate at which interest accrues on the Loan. A Prepayment
     Premium shall also be due and payable on prepayment of all or any portion
     of either Loan prior to scheduled maturity because of acceleration of
     maturity on account of an Event of Default if, at the time of acceleration
     of maturity, the Reinvestment Rate is less than the LIBOR-based Rate at
     which interest is accruing on the Loan. If any portion of the principal
     balance of the Revolving Loan is required to be prepaid in order to reduce
     the balance of the Revolving Loan on account of the requirement of Section
     2.06 of this Agreement, and while interest is accruing on such portion at
     a LIBOR-based Rate, then a Prepayment Premium shall be due and payable in
     addition to the principal amount required to be prepaid, if, at the time
     such principal payment is required, Reinvestment Rate is less than the
     LIBOR-based Rate at which interest is accruing on such portion of the
     Loan. If at the time of any voluntary or mandatory prepayment of any
     portion of the principal of any Loan, interest accrues at both a
     LIBOR-based Rate or Rates and at a Prime-based Rate on portions of the
     Loan, then any prepayment of principal will be applied first to the
     portion of the Loan on which interest accrues at the Prime-based Rate and
     next to the portion or portions at which interest accrues at a LIBOR-based
     Rate or Rates, and if interest accrues on the Loan at more than one
     LIBOR-based Rate, first to that portion or those portions on which
     interest accrues at a Rate or Rates which results in no Prepayment Premium
     or the lowest Prepayment Premium or Premiums.

          (4) On any Banking Day, the Company may request a quotation of the
     LIBOR-based Rates then in effect from the Bank. As soon as possible, and
     in any event before the close of business on the next following Banking
     Day, the Bank shall quote such LIBOR-based Rates. The Company shall then
     have until the end of the Banking Day on which such quotation is given or
     within such shorter time as the Bank may specify, to exercise its option
     to elect any LIBOR-based Rate quoted, subject to all other conditions and
     limitations stated in this Agreement. The period for which any LIBOR-based
     Rate is effective shall begin on the second Banking Day following the day
     on which the quotation is given.

          (5) An election of a LIBOR-based Rate may be communicated to the Bank
     on behalf of the Company only by an Authorized Officer. Such election may
     be communicated by telephone or by telecopy or any other form of written
     electronic communication, or by a writing delivered to the Bank. At the
     request of the Bank, the Company shall confirm any election in writing and
     such written confirmation shall be signed by an Authorized Officer. The
     Bank shall be entitled to rely on any oral or written electronic
     communication of an election of a LIBOR-based Rate which is received by an
     appropriate Bank employee from anyone reasonably believed in good faith by
     such employee to be an Authorized Officer.

          (6) The Bank may elect not to quote a LIBOR-based Rate (the
     "Unavailable LIBOR-based Rate") to any of its customers otherwise eligible
     for the Unavailable LIBOR-based Rate on any day (the Unavailability Date")
     on which the Bank has determined that it is not practical to quote the
     Unavailable LIBOR-based Rate because of the unavailability of sufficient

                                       21

<PAGE>   22



     funds to the Bank for appropriate terms at rates approximating the then
     relevant London Interbank Offered Rate, or because of legal or regulatory
     changes which make it impractical or burdensome for the Bank to lend money
     at the Unavailable LIBOR-based Rate. In such event, and provided that no
     Event of Default or Unmatured Event of Default has occurred and is
     continuing, the Company shall be entitled by written notice given to the
     Bank within ten (10) days of the Unavailability Date to continue the
     LIBOR-based Rate or Rates then accruing on any portion or portions of the
     Loans (regardless of when the such LIBOR-based Rate or Rates otherwise are
     scheduled to expire), until the earlier of (i) that date which is ninety
     (90) days after the Unavailability Date, (ii) that date upon which the
     Bank resumes quoting the Unavailable LIBOR-based Rate; and (iii) the
     occurrence of an Event of Default or Unmatured Event of Default.

          (7) If, as a result of any regulatory change, the basis of taxation
     of payments to the Bank of the principal of or any interest on any Loan
     bearing interest at a LIBOR-based Rate or any other amounts payable
     hereunder in respect thereof, other than taxes imposed on the overall net
     income of the Bank, is changed, or any reserve, special deposit, or
     similar requirement relating to any extensions of credit or other assets
     of or any deposits with or other liabilities of the Bank are imposed,
     modified, or deemed applicable, and the Bank reasonably determines that,
     by reason thereof, the cost to it of making, issuing, or maintaining any
     Loan at a LIBOR-based Rate is increased by an amount deemed by it to be
     material, then the Company shall pay promptly upon demand to the Bank such
     additional amounts as the Bank reasonably determines will compensate for
     such increased costs ("Increased Costs"); provided, however, that (i) the
     Bank shall give the Company ninety (90) days' prior written notice of the
     Bank's intention to collect Increased Costs from the Company ("Increased
     Cost Notice"), and the Bank shall not be entitled to pass-through to or
     collect from the Company Increased Costs incurred by the Bank prior to
     that date which is the ninetieth (90th) day after the delivery of the
     Increased Cost Notice to the Company by the Bank, and (ii) the Company
     shall not be the only borrower of the Bank that is singled out from a
     group of similarly situated borrowers of the Bank subject to this type of
     provision that is requested to remit Increased Costs. Any determination by
     the Bank of Increased Costs made pursuant to the provisions of this
     section shall be final, absent manifest error.

     (b) CALCULATION OF INTEREST. Interest on each of the Loans shall be
calculated on the basis that an entire year's interest is earned in 360 days.

     (c) MANNER OF PAYMENT - APPLICATION. All payments of principal and
interest on the Loans shall be payable at the principal office of the Bank in
Indianapolis, Indiana, in funds available for the Bank's immediate use in that
city and no payment will be considered to have been made until received in such
funds. Unless otherwise agreed to, in writing, or otherwise required by
applicable law, payments will be applied first to accrued, unpaid interest,
then to principal, and any remaining amount to any unpaid collection costs,
late charges and other charges, provided, however, upon delinquency or other
default, the Bank reserves the right to apply payments among principal,
interest, late charges, collection costs and other charges at its discretion.
All prepayments shall be applied to the indebtedness owing hereunder in such
order and manner as the Bank may from time to time determine in its sole
discretion.


                                       22

<PAGE>   23



     (d) AUTOMATIC DEBIT. The Bank may debit when due all payments of principal
and interest due under the terms of this Agreement to any deposit account of
the Company carried with the Bank without further authority.

     SECTION 2.06. MANDATORY PREPAYMENT. If at any time a determination thereof
is to be made, the sum of (a) the principal balance of the Revolving Loan
outstanding at such time, PLUS (b) the aggregate Letter of Credit Exposure
existing at such time, exceeds the Maximum Availability, the Company shall
immediately repay the Revolving Note in an aggregate principal amount, together
with such additional amount as may be necessary, equal to such excess. If an
Event of Default or an Unmatured Event of Default has occurred and is
continuing and the Bank shall have notified the Company of its election to take
any action specified in Section 7.02 of this Agreement, the Maximum
Availability shall be automatically reduced to $0 without any action on the
part of or the giving of notice to the Company by the Bank.


                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

          observance or performance of any covenant, condition or agreement on
          its part to be observed or performed under the terms of its Guaranty
          and continuance of such default for ten (10) days after written
          notice thereof to the Guarantor by the Bank.

               (i) TERMINATION OF GUARANTIES. The termination or purported
          termination of any of the Guaranties.

               (j) DEFAULT UNDER OTHER LOAN DOCUMENTS. The occurrence of any
          "Default" or "Event of Default" as such terms are defined in any of
          the Loan Documents other than this Agreement.

               SECTION 7.02. EFFECT OF EVENT OF DEFAULT. If any Event of
          Default described in Section 7.01 of this Agreement shall occur,

          and the Notes and the Loans evidenced thereby, and all other
          indebtedness and any other payment Obligations of the Company to the
          Bank shall become immediately due and payable, and the obligation of
          the Bank to make any Advance or issue any Letter of Credit shall
          immediately terminate, all without notice of any kind. When any other
          Event of Default has occurred and is continuing, the Bank or any
          other holder of the Notes may accelerate payment of the Loans and
          declare the Notes and all other payment Obligations due and payable,
          whereupon maturity of the Loans shall be accelerated and the Notes
          and the Loans evidenced thereby, and all other payment Obligations
          shall become immediately due and payable and the obligation of the
          Bank to make any Advance or issue any Letter of Credit shall
          immediately terminate, all without notice of any kind. The Bank or
          such other holder shall promptly advise the Company of any such
          declaration, but failure to do so shall not impair the effect of such
          declaration. The remedies of the Bank specified in this Agreement or
          in any other Loan Document shall not be exclusive, and the Bank may
          avail itself of any other remedies provided by law as well as any
          equitable remedies available to the Bank.


                                  ARTICLE VIII

                                 MISCELLANEOUS

               SECTION 8.01. WAIVER -- AMENDMENTS. No delay on the part of the

          partial exercise by any of them of any right, power or remedy
          preclude any other or further exercise thereof, or the exercise of
          any other right, power or remedy. No amendment, modification or
          waiver of, or consent with respect to any of the provisions of this
          Agreement or the other Loan Documents or otherwise of the Obligations
          shall be effective unless such amendment, modification, waiver or
          consent is in writing and signed by the Bank.

     other Loan Documents are made under and will be governed in all cases by
     the substantive laws of the State of Indiana, notwithstanding the fact
     that Indiana conflicts of law rules might otherwise require the
     substantive rules of law of another jurisdiction to apply. EACH CREDIT
     PARTY WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON THE COMPANY AND
     AGREES THAT ALL SERVICE OF PROCESS MAY BE MADE BY MESSENGER, BY CERTIFIED
     MAIL, RETURN RECEIPT REQUESTED, OR BY REGISTERED MAIL DIRECTED TO SUCH

          SECTION 8.08. SUCCESSORS AND ASSIGNS. This Agreement and the other

     assignable without the prior written consent of the Bank.

          SECTION 8.09. WAIVER OF JURY TRIAL. THE CREDIT PARTIES AND THE BANK
     HEREBY VOLUNTARILY, KNOWINGLY, IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY
     RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE (WHETHER BASED

     THE BANK ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT OR ANY
     OTHER LOAN DOCUMENT. THIS PROVISION IS A MATERIAL INDUCEMENT TO THE BANK
     TO PROVIDE THE FINANCING DESCRIBED HEREIN OR IN THE OTHER LOAN DOCUMENTS.

          SECTION 8.10. ARBITRATION. The Bank and the Credit Parties agree that
     upon the written demand of either party, whether made before or after the
     institution of any legal proceedings, but prior to the rendering of any
     judgment in that proceeding, all disputes, claims and controversies
     between them, whether individual, joint, or class in nature, arising from
     this Agreement, any other Loan Document or otherwise, including without
     limitation contract disputes and tort claims, shall be resolved by binding
     arbitration pursuant to the Commercial Rules of the American Arbitration
     Association. Any arbitration proceeding held pursuant to this arbitration
     provision shall be conducted in the city nearest the Company's address
     having an AAA regional office, or at any other place selected by mutual
     agreement of the parties. No act to take or dispose of any collateral
     shall constitute a waiver of this arbitration agreement or be prohibited
     by this arbitration agreement. This arbitration provision shall not

                                       42

<PAGE>   43



     limit the right of either party during any dispute, claim or controversy
     to seek, use, and employ ancillary, or preliminary rights and/or remedies,
     judicial or otherwise, for the purposes of realizing upon, preserving,
     protecting, foreclosing upon or proceeding under forcible entry and
     detainer for possession of, any real or personal property, and any such
     action shall not be deemed an election of remedies. Such remedies include,
     without limitation, obtaining injunctive relief or a temporary restraining
     order, invoking a power of sale under any deed of trust or mortgage,
     obtaining a writ of attachment or imposition of a receivership, or
     exercising any rights relating to personal property, including taking or
     disposing of such property with or without judicial process pursuant to
     Article 9 of the Uniform Commercial Code or when applicable, a judgment by
     confession of judgment. Any disputes, claims or controversies concerning
     the lawfulness or reasonableness of an act, or exercise of any right or
     remedy concerning any collateral, including any claim to rescind, reform,
     or otherwise modify any agreement relating to the collateral, shall also
     be arbitrated; provided, however that no arbitrator shall have the right
     or the power to enjoin or restrain any act of either party. Judgment upon
     any award rendered by any arbitrator may be entered in any court having
     jurisdiction. Nothing in this arbitration provision shall preclude either
     party from seeking equitable relief from a court of competent
     jurisdiction.  The statute of limitations, estoppel, waiver, laches and
     similar doctrines which would otherwise be applicable in an action brought
     by a party shall be applicable in any arbitration proceeding, and the
     commencement of an arbitration proceeding shall be deemed the commencement
     of any action for these purposes. The Federal Arbitration Act (Title 9 of
     the United States Code) shall apply to the construction, interpretation,
     and enforcement of this arbitration provision.
