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 5.75% at December 31, 1997.

On October 4, 1996, the Company executed a three year revolving credit agreement
with Bank One, Indiana, NA ("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 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.

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

On December 23, 1997, the Company entered into two interest rate swap agreements
with Bank One to reduce the impact of changes in interest rates. The first
agreement was for a period of seven years, cancelable by the bank at the end of
five years, whereby the Company agreed to pay the bank a fixed rate of 5.90% per
annum on the notional principal amount of $5.0 million and the bank agreed to
pay the Company the one month LIBOR rate on the same notional amount. The second
agreement was for a period of five years, cancelable by the bank at the end of
three years, whereby the Company agreed to pay the bank a fixed rate of 5.80%
per annum on the notional principal amount of $5.0 million and the bank agreed
to pay the Company the one month LIBOR rate on the same notional amount. The
Company is exposed to credit loss in the event of nonperformance by the bank.
However, the Company does not anticipate nonperformance by the bank.

5. SUBSEQUENT EVENTS:

On January 15, 1998, the Company entered into two interest rate swap agreements

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.

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 and six
months ended December 31, 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



                                     - 13 -

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 $84.6 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 30 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 




                                     - 15 -
<PAGE>   16

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 December 31, 1997 and 1996

Net sales increased 24.0%, or $4.6 million, to $23.9 million from $19.3 million
for the three months ended December 31, 1997, and 1996, respectively.
Acquisitions made during the proceeding twelve months contributed $4.0 million
of the increase in net sales, while same store growth contributed $0.6 million
of the increase. Same store sales increased 3.2% versus the same quarter last
year. Gases and cylinder revenue represented 54.6% of net sales for the three
months ended December 31, 1997, with hard goods representing 45.4%. In
comparison, net sales for the three months ended December 31, 1996 reflected
gases and cylinder revenue at 56.9% and hard goods as 43.1%. This change in
sales mix reflects the effect of acquisitions made during the preceding twelve
months.

Gross profit, which excludes depreciation and amortization, increased 27.9%, or
$2.8 million, to $12.9 million from $10.1 million for the three months ended
December 31, 1997 and 1996, respectively. Acquisitions made during the
proceeding twelve months contributed $2.2 million of the increase in gross
profit, while the base business contributed $0.6 million of the increase. Gross
profit as a percentage of net sales was 54.0% for the three months ended
December 31, 1997, compared to 52.4% for the three months ended December 31,
1996. This change reflected the improvement in product margins, partially offset
by the increase in the mix of hard goods to total sales.

Operating and administrative expenses increased 22.8%, or $1.6 million, to $8.4
million from $6.8 million for the three months ended December 31, 1997 and 1996,
respectively. Of this increase, $1.5 million was related to acquired businesses
and the remaining $0.1 million reflected increases on a same store basis.
Operating and administrative expenses as a percentage of sales decreased to
35.1% for the three months ended December 31, 1997, as compared to 35.4% 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 $0.6 million for the three
months ended December 31, 1997 compared to the same period in 1996, primarily as
a result of acquisitions made during the last twelve months.

Interest expense increased $0.1 million for the quarter, reflecting the
financing of acquisitions made during the last twelve months, partially reduced
by lower interest rates and reductions in debt as a result of the Company's
initial public offering of stock in April 1997.

LIQUIDITY AND CAPITAL RESOURCES



                                     - 17 -
<PAGE>   18

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 December 31, 1997, the Company had working capital of approximately $6.6
million. Funds provided by operations for the six months ended December 31, 1997
were approximately $5.3 million. Funds used for investing activities were
approximately $24.4 million for the six months ended December 31, 1997,
consisting primarily of capital spending and financing for acquisitions. Sources
of funds from financing activities for six months ended December 31, 1997 were
approximately $18.1 million from net borrowings. The Company's cash balance
decreased $1.0 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 7.5%
as of December 31, 1997. The Company pays a fee for the unused portion of the
revolving loan. As of December 31, 1997, availability under the revolving loan
was approximately $2.3 million, with outstanding borrowings of approximately
$24.4 million and outstanding letters of credit of approximately $7.5 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 December 31, 1997 was $15.9 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.

On December 23, 1997, the Company entered into two interest rate swap agreements
with Bank One to reduce the impact of changes in interest rates. The first
agreement was for a period of seven years, cancelable by the bank at the end of
five years, whereby the Company agreed to pay the bank a fixed rate of 5.90% per
annum on the notional principal amount of $5.0 million and the bank agreed to
pay the Company the one month LIBOR rate on the same notional amount. The second
agreement was for a period of five years, cancelable by the 



                                     - 18 -
<PAGE>   19

bank at the end of three years, whereby the Company agreed to pay the bank a
fixed rate of 5.80% per annum on the notional principal amount of $5.0 million
and the bank agreed to pay the Company the one month LIBOR rate on the same
notional amount. The Company is exposed to credit loss in the event of
nonperformance by the bank. However, the Company does not anticipate
nonperformance by the bank.

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 is 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 January 15, 1998, the Company entered into two interest rate swap agreements
with Bank One to reduce the impact of changes in interest rates. The first
agreement was for a period of seven years, cancelable by the bank at the end of
five years, whereby, the Company agreed to pay the bank a fixed rate of 5.43%
per annum on the notional principal amount of $10.0 million and the bank agreed
to pay the Company the one month LIBOR rate on the same notional amount. The
second agreement was for a period of five years, cancelable by the bank at the
end of three years, whereby, the Company agreed to pay the bank a fixed rate of
5.29% per annum on the notional principal amount of $10.0 million and the bank
agreed to pay the Company the one month LIBOR rate on the same notional amount.
The Company is exposed to credit loss in the event of nonperformance by the
bank. However, the Company does not anticipate nonperformance by the bank.

On January 30, 1998 the Company acquired the assets of Liberty Fire Protection
Company, Inc. a supplier of fire protection and safety equipment having
approximately $0.5 million in annualized sales. The Company financed this
transaction from operating funds and notes with the Seller.

On February 5, 1998 the Company entered into an amended and restated credit
facility with Bank One, as agent. The new credit facility increased the maximum
revolving note borrowings to $75.3 million and refinanced the term note at the
existing balance of $14.7 million. The new scheduled maturity date of the term
note is October 4, 2003. The new scheduled maturity date of the revolving note
is January 16, 2001. The Company paid the banks fees of approximately $210,000,
which will be amortized over the term of the notes. 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.

                  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 the Credit Parties fail to
         deliver when due the Financial Statements and compliance certificates

         Percentage and the Applicable Spread shall be adjusted (without further
         prior notice by the Agent or any of the Banks to the Company) to the

         Commitment Fee Percentage and the Applicable Spread provide for a Ratio
         of Total Funded Debt to EBITDA with respect to the Credit Parties and

         provided for in this Agreement in the event of the violation of the
         covenant stated in subsection 5.01(g) of this Agreement,

                                 Borrowing Terms

                  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 and the other Credit Parties
made in this Agreement and the other Loan Documents, each Bank severally agrees
to make the Loans and issue or risk participate with respect to the Letters of
Credit as described in this Article II.

                  Section 2.02.  The Revolving Loans.

                  (a) The Commitment -- Use of Proceeds. Each of the Banks
severally agrees, subject to the terms and conditions of this Agreement, to make
Advances to the Company on a revolving basis (collectively, the "Revolving
Loans") from time to time from and after the Closing Date until the Revolving
Loans Maturity Date, with the principal balance of all of the Revolving Loans
not to exceed in the aggregate at any time the Maximum Revolver Availability and
with the outstanding principal balance of all Advances made by each Bank not to
exceed at any time such Bank's Commitment Percentage of the Maximum Revolver
Availability. Advances 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 Loans under this Agreement are a continuation,
on amended terms, of the "Revolving Loan" extended to the Company by Bank One
under the Original Agreement (the "Prior Revolving Loan") and the Company
affirms, acknowledges and agrees that the outstanding principal balance of the
Prior Revolving Loan as of the Closing Date is $25,055,585.19, being the unpaid
principal amount of the Prior Revolving Loan immediately prior to the execution
of this Agreement.

                  (b) Method of Borrowing. The obligation of the Company to
repay the Revolving Loans shall be evidenced by promissory notes executed by the
Company to each of the Banks 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 "Revolving Notes"). So long as
no Event of Default or Unmatured Event of Default shall have occurred and be
continuing and until the Revolving Loans Maturity Date, the Company may borrow,
repay (subject to the requirements of Section 2.06 of this Agreement) and
reborrow under the Revolving Notes on any Banking Day, provided that Company
shall not be entitled to receive and the Banks 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 amount of the Remaining Availability as of the date of such Advance;
or (iii) if after making such Advance the aggregate principal balance of the
Revolving Loans would exceed the Maximum Revolver Availability. Each Advance
shall be conditioned upon receipt by the Agent from the Company of an
Application for Revolving Loans Advance and an Officer's Certificate, provided
that the Agent may, at its discretion, make a 

                                      -16-
<PAGE>   17

disbursement upon the oral request of the Company made by an Authorized Officer,
or upon a request transmitted to the Agent by telecopy or by any other form of
written electronic communication (all such requests for Advances being hereafter
referred to as "informal requests"). The Agent shall promptly give each Bank
telephonic notice (confirmed in writing, which may be by telecopy) of each
Advance request. In so doing, the Agent 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 Loans Advance and Officer's
Certificate if the Agent 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 then outstanding, and that the making of the requested Advance
would not cause the aggregate principal balance of the Revolving Loans to exceed
the Maximum Revolver Availability. All borrowings and reborrowings and all
payments shall be in amounts of not less than Fifty Thousand Dollars ($50,000),
except for payment of the entire aggregate principal balance of the Revolving
Loans 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 Loans Advance, or at the Agent'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
Loans, the Agent shall disburse the amount of the requested Advance to the
Company as provided in Section 2.02(c). Except as the Agent and the Banks may
otherwise determine in their absolute discretion, no Advance will be made on the
day the Agent receives the Application for a Revolving Loans Advance or informal
request for Advance is received by the Agent unless such Application or request
is received by the Agent prior to 12:00 noon, Indianapolis, Indiana time.
Advances by each Bank and payments by the Company shall be recorded by each 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 each Bank. The Banks' books and records shall be presumed
prima facie to be correct as to such matters.

                  (c) Disbursement of Funds. On the date each Advance is to be
made, each Bank will make available to the Agent its Commitment Percentage of
the Advance requested to be made on such date in U.S. Dollars and in immediately
available funds, not later than 1:00 p.m. (Indianapolis time) at the account
specified in Section 2.05(c), and the Agent will make available to the Company
the aggregate of the amounts so made available by the Banks, in immediately
available funds by disbursing such amounts to an account established by the
Company with the Agent for that purpose. Unless the Agent shall have been
notified by any Bank prior to the date of an Advance that such Bank does not
intend to make available to the Agent such Bank's Commitment Percentage of the
Advance to be made on such date, the Agent may assume that such Bank has made
such amount available to the Agent on the date of the Advance and the Agent may,
in reliance upon such assumption, make available to the Company such Bank's
Commitment Percentage thereof. If such Bank does not in fact make available to
the Agent such amount on the date of such Advance, the Agent shall be entitled
to recover such amount on demand from such Bank. If a Bank does not pay such
amount forthwith upon the Agent's demand therefor, the Agent shall promptly
notify the Company and the Company shall within one Banking Day repay a
corresponding amount to the Agent, together with interest on such corresponding
amount in respect of each day from and including the date such corresponding
amount was made available by the Agent to the Company to the date such
corresponding amount is recovered by the Agent, at the interest rate applicable
to the related Advance during the period in question (which amounts the Agent
shall be entitled to retain for its own account). Nothing herein shall be deemed
to relieve any Bank from its obligation to fund its Commitment Percentage of
each requested Advance, or to prejudice any rights which the Company may have
against a Bank as a result of any failure by such Bank to fund its Commitment
Percentage of any requested Advance.

                  The Company agrees that upon demand by any Bank (which demand
shall be accompanied by a statement setting forth the basis for the calculations
of the amount being claimed) the Company will indemnify such Bank against any
net loss or expense which such Bank sustains or incurs, as reasonably determined
by such Bank, as a result of any failure of the Company to borrow any Advance on
the date specified therefor in an Advance request.

                  (d) Interest on the Revolving Loans. The principal amount of
the Revolving Loans outstanding from time to time shall bear interest until the
Revolving Loans 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 Loans Maturity Date on any part or on the
entire outstanding principal balance of the Revolving Loans as to which no
LIBOR-based Rate previously elected 

                                      -17-
<PAGE>   18

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
Loans Maturity Date. After the Revolving Loans Maturity Date, and until paid in
full, the principal amount of the Revolving Loans outstanding from time to time
shall bear interest at a per annum rate equal to the Prime Rate plus Two Percent
(2%) per annum. Accrued interest shall be due and payable quarterly on the last
Banking Day of March, 1998, and on the last Banking Day of each successive June,
September, December and March thereafter until the Revolving Loans Maturity
Date, at which time the entire unpaid principal balances of the Revolving Loans
and all unpaid, accrued interest thereon, shall be due and payable in full
without demand. After the Revolving Loans Maturity Date, interest shall be
payable as accrued and without demand.

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

                  Section 2.03.     Standby Letters of Credit.

                  (a) Standby Letters of Credit -- General. Bank One 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 standby letters 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 of the Company
other than Credit Enhancement (each a "Letter of Credit"), provided that:

                           (1) The aggregate Letter of Credit Exposure shall not
         at any time exceed the lesser of (A) Twenty-Five Million Dollars
         ($25,000,000) or (B) the Maximum Availability at such time minus the
         aggregate outstanding principal balance of all Revolving Loans at such
         time;

                           (2) The Company shall not request and Bank One 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 Loans Maturity Date;
         (iii) if, after giving effect to such issuance, the aggregate Letter of
         Credit Exposure would exceed the lesser of (A) Twenty-Five Million
         Dollars ($25,000,000) or (B) the Maximum Availability then outstanding
         minus the then aggregate outstanding principal balance of all Revolving
         Loans; (iv) if the face amount of such Letter of Credit would exceed
         the then outstanding Remaining Availability; or (v) for any purpose
         other than those permitted hereunder;

                           (3) Bank One 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 Bank One or any
         requirement of applicable law;

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

                           (5) Bank One shall have received from the Company an
         application and reimbursement agreement for the Letter of Credit in
         form and substance satisfactory to Bank One 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 on
         behalf of the Company.

                                      -18-
<PAGE>   19

                  (b) Risk Participation. Each Bank (other than Bank One) hereby
agrees that, immediately upon the issuance of each Letter of Credit and as of
the Closing Date as to the Initial Letters of Credit, such Bank shall purchase,
and shall be deemed to have irrevocably purchased from Bank One (without the
necessity of the execution or delivery by Bank One or such Bank of any further
or additional document evidencing such purchase) a risk participation in such
Letter of Credit and the obligations of Bank One with respect to Drafts
thereunder (including any Letter of Credit Loan), in an amount equal to such
Bank's Commitment Percentage.

                  (c) Letter of Credit Procedures. Whenever the Company desires
the issuance of a Letter of Credit, it shall deliver to Bank One 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 Bank One 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 Bank One, 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 Bank One, 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.

                  (d) Draws under Letters of Credit. Upon presentation of a
Draft under any Letter of Credit by the beneficiary thereof, Bank One shall
notify the Company and the Banks of the receipt thereof ("Draft Notice") not
later than one Banking Day prior to the date on which Bank One 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 or the
obligations of the Banks hereunder. Upon receipt of the Draft Notice, the
Company shall make or cause to be made an irrevocable deposit with Bank One 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, Bank One 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
addressed by this Agreement and contains provisions that are different from
those set forth in this Agreement.

                  (e) Reimbursement Obligations of the Company. The Company
hereby agrees to reimburse Bank One, on demand, the amount paid by Bank One to
settle its obligations in respect of each Draft under each Letter of Credit
(whether such amount is paid by virtue of Bank One's honor of any Draft or
otherwise) to the extent that a Reimbursement Amount is not available to Bank
One 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 Bank One 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 Three Percent (3%) per annum. A demand for
payment of each Reimbursement Amount and Letter of Credit Loan shall be deemed
to have been made by Bank One on the date of the corresponding payment by Bank
One 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 Loans to pay any Reimbursement Amount or Letter of Credit Loan.

                                      -19-
<PAGE>   20

                  The obligation of the Company to reimburse Bank One 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 Bank One 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;

provided however, that the Company shall not be obligated to reimburse Bank One
for any wrongful payment or disbursement made or to be made by Bank One under
any Letter of Credit as a result of acts or omissions constituting gross
negligence or willful misconduct on the part of Bank One. 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 Bank One 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, Bank One 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
related solely to the Draft on the Letter of Credit, the Company shall
immediately notify Bank One thereof in writing, and the Company shall be deemed
to have waived any such claim or defense against Bank One 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 Bank One 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.

                  (f) Default by Company. In the event the Company fails to
deposit the Reimbursement Amount with Bank One, or if for any other reason the
Reimbursement Amount is not available to settle Bank One's obligations under a
Draft, the Agent shall make a demand on the Banks for funding pursuant to this
section. Each Bank (other than Bank One) shall forthwith (and in any event, not
later than 1:00 p.m., Indianapolis 

                                      -20-
<PAGE>   21

time, on the day the Agent has indicated to the Banks as the day such Draft is
to be honored, or if such demand is made after 10:00 a.m., Indianapolis time on
the day indicated for honor of the Draft, then not later than 1:00 p.m.,
Indianapolis time, on the first Business Day immediately following the day such
demand is made), make available to the Agent at its principal banking offices
immediately available funds in an amount equal to its Commitment Percentage of
the amount of the Draft, which funds shall be immediately remitted by the Agent
to Bank One to be used by it to settle its obligations under such Draft. In
addition, if for any reason the Reimbursement Amount is recovered in whole or in
part from the Agent or Bank One or a recovery is obtained from the Agent or Bank
One based on such deposit, then the Agent shall make demand on each Bank for,
and each Bank shall pay to the Agent (for the account of Bank One if the
recovery is obtained from it) an amount equal to such Bank's Commitment
Percentage of the amount of the recovery (provided that Bank One shall not be
required to make any such payment in regard to an amount recovered from it).
Each payment by a Bank to the Agent pursuant to the preceding sentence of the
amount of any Reimbursement Amount recovered shall be deemed to be a Letter of
Credit Loan payable with interest as provided above. If for any reason the
foregoing payments to the Agent may not be deemed to be a Letter of Credit Loan,
each payment by a Bank to the Agent shall be considered to be the purchase of a
participation in Bank One's or the Agent's rights and claims arising as a result
of such recovery, if any, in an amount equal to such Bank's Commitment
Percentage thereof.

                  (g) Indemnity. The Company agrees to protect, indemnify and
save Bank One and the Banks 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 Bank
One or any of the other Banks 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 gross negligence or willful misconduct of Bank One, as
determined by a court of competent jurisdiction, or (b) the failure of Bank One
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 Bank One, on the
other, the Company assumes 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, Bank One 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 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 Bank One, including, without limitation, any
Government Acts; and (i) for any action taken or omitted by Bank One 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 Bank Ones'
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 Bank One, 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 Bank One to any resulting liability
to the Company. In furtherance thereof, Bank One 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.

                  (h) Letter of Credit Fees. The Company covenants and agrees to
pay to Bank One, 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 (a "L/C Commission") equal to (i) the Applicable
Spread then in effect, if the amount of the total Letter of Credit Exposure
after issuance of such Letter of Credit exceeds twenty percent (20%) of the sum
of the principal balances of the Revolving Loans, the Term Loan and the total
Letter of Credit Exposure, all as of immediately after issuance of such Letter
of Credit, or (ii) otherwise, the Applicable LOC Fee Percentage then in effect.
Each L/C Commission shall be deemed fully earned and nonrefundable when due. The
Company shall pay Bank One'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 L/C Commissions and fees may be debited by Bank One to any
deposit account of the Company carried with Bank One without further authority,
and in any event, shall be paid by the Company within ten (10) days following
billing. Upon receipt of each L/C Commission, Bank One shall retain 0.125% of
the amount of the Letter of Credit for which such commission is charged as its
independent fee for issuing such Letter of Credit and disburse the remainder of
the L/C Commission to each Bank, including Bank One, pro rata in accordance with
each Bank's Commitment Percentage. Promptly following the Closing Date, each
Bank (other than Bank One) shall receive payment from Bank One for each Initial
Letter of Credit in an amount equal to its Commitment Percentage of the L/C
Commission previously received by Bank One for such Initial Letter of Credit,
proportionately reduced to reflect the period of time such Letter of Credit was
outstanding prior to the Closing Date. All transaction fees shall be retained by
Bank One.

                  (i) Initial Letters of Credit. The Initial Letters of Credit
for all purposes shall be deemed to be Letters of Credit for all purposes
hereunder, except that no L/C Commission shall be due and payable by the Company
on the Initial Letters of Credit hereunder until renewal, extension or
replacement thereof.

                  Section 2.04      The Term Loan.

                  (a) The Term Loan -- General. Each Bank severally agrees,
subject to the terms and conditions of this Agreement, to loan to the Company
the principal amount equal to its Commitment Percentage of Fourteen Million
Seven Hundred Ten Thousand Four Hundred Fifteen Dollars ($14,710,415.00) for the
term period beginning on the Closing Date and ending on the Term Loan Maturity
Date (collectively, the "Term Loan").

                  The Term Loan under this Agreement is a continuation, on
amended terms, of the "Term Loan" extended to the Company by Bank One under the
Original Agreement (the "Prior Term Loan") and the Company affirms, acknowledges
and agrees that the outstanding aggregate principal balance of the Term Loan as
of the Closing Date is $14,710,415.00, being the unpaid principal amount of the
Prior Term Loan immediately prior to the execution of this Agreement.

                  (b) The Term Notes. The obligation of the Company to repay the
Term Loan shall be evidenced by promissory notes executed by the Company to each
of the Banks in the form of EXHIBIT F 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 Notes"). The principal of the Term
Loan shall be repayable in equal quarterly installments of $639,585.00 each,
which quarterly installments shall be due and payable on the last Banking Day of
March, 1998, and on the last Banking Day of each successive calendar quarter
thereafter until the Term Loan Maturity Date, at which time the entire aggregate
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 principal 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 aggregate 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

                                      -22-
<PAGE>   23

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%) per annum. Prior to the Term Loan Maturity Date, interest shall
be due and payable on the last Banking Day of each calendar quarter beginning on
the last Banking Day of March, 1998 and on the last Banking Day of each
successive June, September, December and March. After the Term Loan Maturity
Date, interest shall be payable as accrued and without demand.

                  Section 2.05. Provisions Applicable to All the Loans. The
following provisions are applicable to all 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 ten (10) LIBOR-based Rate elections may be in effect under
         the Loans at any one time.

                           (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 balances of the Revolving Loans
         is required to be prepaid in order to reduce the balance of the
         Revolving Loans 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 amounts required to be prepaid, if, at the
         time such principal payment is required, the 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 Agent. As
         soon as possible, and in any event before the close of business on the
         next following Banking Day, the Agent 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 Agent
         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 Agent on behalf of the Company only by an
         Authorized Officer. Such election may be communicated by telephone or
         by 

                                      -23-
<PAGE>   24

         telecopy or any other form of written electronic communication, or
         by a writing delivered to the Agent. At the request of the Agent, the
         Company shall confirm any election in writing and such written
         confirmation shall be signed by an Authorized Officer. The Agent 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
         employee of the Agent from anyone reasonably believed in good faith by
         such employee to be an Authorized Officer.

                           (6) The Agent 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 Agent has determined that it is not
         practical to quote the Unavailable LIBOR-based Rate because of the
         unavailability of sufficient funds to the Banks 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 Banks 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 Agent 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 Agent 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 any of the Banks of any 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 any of
         the Banks, 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 any of the Banks are imposed,
         modified, or deemed applicable, and a 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
         Agent such additional amounts as such Bank reasonably determines will
         compensate for such increased costs ("Increased Costs"); provided,
         however, that (i) the Agent shall give the Company ninety (90) days'
         prior written notice of such Bank's intention to collect Increased
         Costs from the Company ("Increased Cost Notice"), and a 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 a 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 Agent
in Indianapolis, Indiana, in funds available for the Agent's immediate use in
that city at the Agent's account at:

                    Bank One, Indiana, National Association
                    ABA #074000010
                    Attn: Commercial Loan Note Servicing
                    Re: Valley National Gases, Inc.
                    Account No. 05315101000263

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 

                                      -24-
<PAGE>   25

delinquency or other default, the Banks reserve the right to apply payments
among principal, interest, late charges, collection costs and other charges at
their discretion, as determined by the Required Banks. All prepayments shall be
applied to the indebtedness owing hereunder in such order and manner as the
Required Banks may from time to time determine in their sole discretion.

                  (d) Automatic Debit. The Agent, on behalf of the Banks, 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 Agent
without further authority.

                  Section 2.06. Mandatory Prepayment/Reduction of Maximum
Availability. If at any time a determination thereof is to be made, the sum of
(a) the aggregate principal balance of the Revolving Loans 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 Notes 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 Agent shall have notified the Company of the
Required Banks' 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 Agent or
the Banks.

                  Section 2.07. Pro Rata Treatment. All borrowings, conversions
and payments shall be effected so that after giving effect thereto the
Obligations of the Company to each Bank (which shall be deemed to include, with
respect to each Bank, its Commitment Percentage of the Letter of Credit
Exposure) shall be equal to such Bank's Commitment Percentage of the Obligations
of the Company to all Banks. The Agent shall distribute all payments to the
Banks on the same day of receipt if received prior to Noon, Indianapolis,
Indiana time, otherwise on the next Banking Day. References in any of the Loan
Documents to Indianapolis time shall mean time as kept in Indianapolis, Indiana.
If any Bank, whether by setoff or otherwise, has payment made to it upon its
Revolving Note or Term Note in a greater proportion than that received by any
other Bank, such Bank agrees, promptly upon demand, to purchase such
participation in the Revolving Notes and Term Notes held by the other Banks so
that after such purchase the purchasing Bank shall share such excess payment
ratably with each of them. If any Bank, whether in connection with setoff or
amounts which might be subject to setoff or otherwise, receives Collateral or
other protection for Borrower's Obligations to such Bank hereunder, such Bank
agrees, promptly upon demand, to take such action necessary such that all Banks
share in the benefits of such Collateral ratably in proportion to their
Commitment Percentages. In case any such payment is disturbed by legal process
or otherwise, appropriate further adjustments shall be made.

                  Section 2.08. Agent Fees. The Company shall pay to the Agent
fees for its services (the "Agent Fee Agreement"), the amounts and payment terms
of which are set forth in a separate agreement between the Agent and the
Company.

                  Section 2.09. Setoff. Upon the occurrence of any Event of
Default (including any applicable cure period) and during the continuance of any
Event of Default, each of the Banks is hereby authorized at any time and from
time to time, without notice to any Credit Party (any such notice being
expressly waived by the Credit Parties), to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by each of the Banks to or for the
credit or the account of the Credit Party against any and all of the Obligations
irrespective of whether or not any Bank shall have made any demand under this
Agreement, the Revolving Notes, the Term Notes or any other Loan Document and
although such Obligations may be unmatured. Each Bank exercising such right of
setoff and application agrees to promptly notify the Credit Party after any such
setoff and application; provided that, the failure to give such notice shall not
affect the validity of such setoff and application. The rights of each Banks
under this Section 2.09 are in addition to all other rights and remedies
(including, without limitation, other rights of setoff) which such Bank may
have.

                  (e) Warranties and Representations. Any warranty or
representation made by any Credit Party or any Guarantor in this Agreement or

misleading in any material respect when made, or any schedule, certificate,
financial statement, report, notice, or other writing furnished by any Credit
Party or any Guarantor to the Bank proving to have been false or misleading in
any material respect when made or delivered, provided that the foregoing shall

Section 7.01) and continuance of such failure for thirty (30) days after notice
thereof to such Credit Party or such Guarantor from the Agent.

                  (h) Guaranty Defaults. Any Guarantor shall default in the due
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
Agent.

                  (i) Termination of Guaranties. The termination or purported
termination of any of the Guaranties.

                  (j) Default under Other Loan Documents. The occurrence of any

the Loans shall immediately be accelerated and the Notes and the Loans evidenced

Company to the Banks shall become immediately due and payable, and the
obligation of the Banks to make any Advance and the obligation of Bank One to
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
Required Banks 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 Banks to make any Advance and the obligation of Bank One to issue any
Letter of Credit shall 

                                      -39-

immediately terminate, all without notice of any kind. The Agent 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 Agent and the Banks
specified in this Agreement or in any other Loan Document shall not be
exclusive, and the Agent and the Banks each may avail itself of any other
remedies provided by law as well as any equitable remedies available to the
Banks.

                                  ARTICLE VIII

                                      Agent

                  Section 8.01. Agent. This Article specifies rights and
obligations among and between the Banks and the Agent. The Credit Parties
acknowledge the existence of limitations in Agent's authority but shall be
entitled to rely upon the authority of the Agent as conferred by this Article
and otherwise specified in this Agreement or any other Loan Document.

                  Section 8.02. Appointment of Agent. Each Bank hereby appoints
and authorizes the Agent to act as its agent under this Agreement and the other
Loan Documents to receive payments made in respect of the Revolving Notes and
the Term Notes and in respect to Letter of Credit Loans and to have such powers
as are specifically delegated to the Agent by the terms of this Agreement and
the other Loan Documents, together with such other powers as are reasonably
incidental thereto.

                  Section 8.03. Powers and Immunities of Agent.

                  (a) Powers. The Agent shall have no rights or duties or
responsibilities except those expressly set forth in this Agreement and the
other Loan Documents, and the Agent shall not by reason of this Agreement or any
of the other Loan Documents be a trustee or fiduciary for any Bank. Neither the
Agent nor any of its directors, officers, agents, attorneys or employees shall
be responsible for any recitals, statements, representations or warranties
contained in this Agreement or any other Loan Documents, or received by any of
them under this Agreement or any other Loan Documents, or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any other Loan Documents or for any failure by the Credit Parties
to perform any of their obligations hereunder or thereunder. The Agent may
employ agents and attorneys and shall not be responsible, except as to money or
securities received by it or its authorized agents, for the negligence or
misconduct of any such agents or attorneys selected by it with reasonable care.
Neither the Agent nor any of its directors, officers, employees or agents shall
be liable or responsible for any action taken or omitted to be taken by it to
any Bank, Credit Party or any other Person under this Agreement or any other
Loan Documents or in connection herewith, except for its or their own gross
negligence or willful misconduct.

                  (b) Reliance by Agent. The Agent shall be entitled to rely
upon any certification, notice or other communication (including any thereof by
telephone, telex, telegram, cable or telecopy) received by it in connection with
this Agreement or the other Loan Documents believed by it to be genuine and
correct and to have been signed or sent by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel, independent
accountants and other experts selected by Agent. As to any matters not expressly
provided for by this Agreement or the other Loan Documents, the Agent shall in
all cases be fully protected in acting, or in refraining from acting, hereunder
in accordance with instructions signed by the Required Banks, and such
instructions and any action taken or failure to act pursuant thereto shall be
binding on all of the Banks.

                  (c) Defaults. The Agent shall not be deemed to have knowledge
of the occurrence of an Event of Default or Unmatured Event of Default (other
than (i) the non-payment of principal of or interest on the Notes or any other
amounts payable under this Agreement or (ii) the failure of the Credit Parties
to provide timely the statements and certification required by Section
5.01(b)(1) through (4) hereof) or to comply with a request or demand by the
Agent unless the Agent has received written notice or other written
documentation from a Bank or from a Credit Party indicating that an Event of
Default or Unmatured Event of Default has occurred. In the event that the Agent
receives such a notice of the occurrence of an Event of Default or Unmatured
Event of Default, the Agent shall give prompt notice thereof to the Banks (and
shall give each Bank prompt notice of each such non-payment). The Agent shall
(subject to Section 

                                      -40-
<PAGE>   41

8.03(g) of this Agreement) take such action with respect to such Event of
Default or Unmatured Event of Default as shall be directed by the Required
Banks.

                  (d) Rights as a Bank. With respect to the Loan Documents, Bank
One, in its capacity as a Bank hereunder, shall have the same rights and powers
hereunder as any other Bank and may exercise the same as though it were not
acting as the Agent. The affiliates of any Bank (including Bank One) may
(without having to account therefor to any other Bank) accept deposits from,
lend money to and generally engage in any kind of banking, trust or other
business with a Credit Party. Bank One may accept fees and other consideration
from a Credit Party for services in connection with this Agreement or otherwise
without having to account for the same to the other Banks except as specified
herein. In so doing, no Bank shall violate the provisions of this Agreement or
the other Loan Documents.

                  (e) Indemnification. Each of the Banks agrees to indemnify the
Agent (to the extent not reimbursed by a Credit Party) ratably in proportion to
its Commitment Percentage for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of this
Agreement or any other Loan Documents or the enforcement of any of the terms
hereof or of any such other documents, provided that no Bank shall be liable for
any of the foregoing to the extent they arise from the gross negligence or
willful misconduct of the Agent.

                  (f) Non-Reliance on Agent and other Banks. Each Bank agrees
that it has, independently and without reliance on the Agent or any other Bank,
and based on such documents and information as it has deemed appropriate, made
its own credit analysis of the Credit Parties and its decision to enter into
this Agreement and that it will, independently and without reliance upon the
Agent or any other Bank, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement and the other Loan Documents.
The Agent shall not be required to keep itself informed as to the performance or
observance by the Credit Parties of this Agreement or any other Loan Documents
or to inspect the properties or books of the Credit Parties unless an inspection
of the properties or books is requested in writing by the Required Banks.

                  (g) Failure to Act. Except for action expressly required of
the Agent hereunder, the Agent shall in all cases be fully justified in failing
or refusing to act under this Agreement and the other Loan Documents unless it
shall be indemnified to its satisfaction by the Banks against any and all
liability and expenses which may be incurred by it by reason of taking or
continuing to take any such action.

                  (h) Resignation or Removal of Agent. Subject to the
appointment and acceptance of a successor Agent as provided below, the Agent may
resign at any time by giving notice thereof to the Banks and the Company, and
the Agent may be removed at any time with or without cause by the Required
Banks. Upon such resignation or removal, the Required Banks shall have the right
to appoint a successor Agent. If no successor Agent shall have been so appointed
by the Required Banks or such successor shall not have accepted such appointment
within thirty (30) days after the retiring Agent's giving of notice of
resignation or after the removal of the Agent, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent, which shall be a bank which has
an office in the United States and having a combined capital and surplus of at
least Five Hundred Million Dollars ($500,000,000.00). Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations as Agent under this Agreement and the other Loan
Documents. After any retiring Agent's resignation or removal hereunder as Agent,
the provisions of this Section 8.03 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
Agent.

                  (i) Collateral. Any Collateral in the possession of the Agent
(as agent for the Banks) shall be held for the ratable benefit of the Banks and
the Agent, subject to any prior lien therein held by the Agent in its individual
capacity and not as agent for the Banks. As to Collateral in its possession, the
Agent shall exercise only such degree of care as it would exercise for its own
account.

the Agent or the Banks, or any holder of the Notes in the exercise of any right,
power or remedy shall operate as a waiver thereof, nor shall any single or
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 Required Banks.

                  Section 9.04. SEVERABILITY. If any provision of this Agreement
or any other Loan Document is determined to be illegal or unenforceable, such

                                      -43-
<PAGE>   44

provisions of this Agreement or such Document and the remaining provisions shall
be enforceable in accordance with their terms.

                  Section 9.05. CAPTIONS. Section captions used in this
Agreement are for convenience only and shall not affect the construction of this
Agreement.

                  Section 9.06. GOVERNING LAW/PROCESS. Except as may otherwise
be expressly provided in any other Loan Document, this Agreement and all 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 CREDIT PARTY AT THE ADDRESS STATED IN SECTION 9.02 OF THIS
AGREEMENT. NOTHING CONTAINED IN THIS SECTION SHALL AFFECT THE RIGHT OF THE BANK
TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

                  Section 9.07. PRIOR AGREEMENTS, ETC. This Agreement supersedes
all previous agreements and commitments made by the Agent or the Banks and the
Credit Parties with respect to the Loans and all other subjects of this
Agreement, including, without limitation, any oral or written proposals or
commitments made or issued by the Agent or the Banks.

                  Section 9.08. SUCCESSORS AND ASSIGNS.

                  (a) This Agreement and the other Loan Documents shall be
binding upon and shall inure to the benefit of the Credit Parties, the Agent and
the Banks and their respective successors and assigns, provided that the Credit
Parties' rights under this Agreement shall not be assignable without the prior
written consent of the Banks.

                  (b) Any Bank may, in the ordinary course of its business and
in accordance with applicable law, at any time assign to one or more banks or
other entities (a "Purchaser") all or any part of its Revolving Loans, Term
Loan, Letter of Credit Exposure, Commitment and its rights and obligations under
its Notes and under this Agreement, pursuant to a form of assignment acceptable
to such Bank and such Purchaser, provided that (i) the Bank shall have given the
Agent and the Company not less than seven (7) Banking Days prior written notice
of such assignment, (ii) each individual assignment shall be in an amount of not
less than $10,000,000, (iii) the prior written consent of the Agent shall be
required prior to an assignment becoming effective with respect to a Purchaser
which is not then a Bank or an affiliate thereof, which consent shall not be
unreasonably withheld, (iv) unless (1) an Event of Default or Unmatured Event of
Default has occurred and is continuing, or (2) such assignment would result from
the sale or acquisition by or of any Bank, the prior written consent of the
Company shall be required prior to an assignment becoming effective with respect
to a Purchaser which is not then a Bank or an affiliate thereof, which consent
shall not be unreasonably withheld, (v) the senior unsecured debt of such
Purchaser must be rated by Moody's Investors Service, Inc. as Baa1 or higher;
and (vi) the Purchaser shall have paid an assignment fee to the Agent, for its
account, in the amount of $3,500. Notwithstanding the foregoing provisions of
this Section 9.08(b), any Bank may at any time assign all or any portions of its
Revolving Loans, Term Loan, Revolving Note, Term Note and its risk participation
in the Letter of Credit Exposure to a Federal Reserve Bank (but no such
assignment shall release such Bank from any of its obligations hereunder).

                  (c) Upon delivery to the Agent and the Company of a notice of
assignment, together with any consent required by this Section 9.08, such
assignment shall become effective on the effective date specified in such
notice, and Exhibit B shall be deemed to have been amended to reflect such
Purchaser as a Bank, and the appropriate adjustments of the Commitments and
Commitment Percentages of the Banks. On and after the effective date of such
assignment, such Purchaser shall for all purposes be a Bank party to this
Agreement and shall have all the rights and obligations of a Bank under this
Agreement, to the same extent as if it were an original party hereto, and no
further consent or action by the Company, the Agent or any other Bank shall be
required to release the transferor Bank with respect to the percentage of the
Revolving Loans, Term Loan, Letter of Credit Exposure and Commitment assigned to
such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant
to this Section 9.08, the transferor 

                                      -44-
<PAGE>   45

Bank and the Company shall make appropriate arrangements so that replacement
Notes are issued to such transferor Bank in principal amounts reflecting its pro
rata share of the Aggregate Commitment.

                  (d) The Company authorizes each Bank to disclose to any
Purchaser or prospective Purchaser or any other entity acquiring an interest in
this Agreement or its Notes by operation of law (each a "Transferee") and any
prospective Transferee any and all information in such Bank's possession
concerning the creditworthiness of the Company, the other Credit Parties and
their respective Subsidiaries.

                  (e) This Agreement and all covenants, representations and
warranties made herein and in any of the other Loan Documents shall survive the
making of the Loans, the execution and delivery of the Loan Documents and shall
continue in effect so long as any Obligations remain unpaid or any Commitment
remains outstanding.

                  Section 9.09. WAIVER OF JURY TRIAL. EACH OF THE CREDIT
PARTIES, THE AGENT AND EACH OF THE BANKS HEREBY VOLUNTARILY, KNOWINGLY,
IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY RIGHT TO HAVE A JURY PARTICIPATE IN
RESOLVING ANY DISPUTE (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) BETWEEN
OR AMONG THE CREDIT PARTIES, THE AGENT AND THE BANKS ARISING OUT OF OR IN ANY
WAY RELATED TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT. THIS PROVISION IS A
MATERIAL INDUCEMENT TO THE AGENT AND THE BANKS TO PROVIDE THE FINANCING
DESCRIBED HEREIN OR IN THE OTHER LOAN DOCUMENTS. NEITHER THE COMPANY OR ANY
GUARANTORS NOR THE BANKS WILL SEEK TO CONSOLIDATE ANY SUCH ACTION IN WHICH A
JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL HAS NOT
BEEN OR CANNOT BE WAIVED.

                  Section 9.10. ARBITRATION. The Agent, the Banks and the Credit
Parties agree that upon the written demand of any 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 limit the right of any 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, bankruptcy 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 any party. Judgment
upon any award rendered by any arbitrator may be entered in any court having
jurisdiction. Nothing in this arbitration provision shall preclude any 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.

                  Section 9.11. Amendments. Subject to the provisions of this
Section, the Required Banks (or the Agent with the consent in writing of the
Required Banks) and the Credit Parties may enter into agreements supplemental
hereto for the purpose or adding or modifying any provisions of the Loan
Documents or changing in any manner the 

                                      -45-
<PAGE>   46

rights of the Banks, the Agent or the Credit Parties hereunder or waiving any
Event of Default; provided, however, that no such supplemental agreement shall,
without the consent of each Bank:

                  (a) Extend the maturity of any Revolving Note or Term Note or
reduce the principal amount thereof, or reduce the rate, extend or change the
time of payment of principal, interest or fees hereunder or thereunder, or amend
the terms of Section 2.03(a)(3)(i) so as to lengthen the maximum permitted
expiration date of a Letter of Credit.

                  (b) Reduce the percentages specified in the definition of
Required Banks.

                  (c) Extend the Scheduled Revolving Loans Maturity Date or the
Scheduled Term Loan Maturity Date or increase the amount of the Commitment of
any Bank, or permit the Company to assign its rights under this Agreement.

                  (d) Amend this section.

                  (e) Waive any Event of Default arising from a failure to pay 
principal of or interest on a
Loan.

                  (f) Affect the rights, duties or obligations of the Agent.

                  (g) Release any Guaranty or asset having a value in excess of
$1,000,000.00 at the time of release from any lien or security interest held by
the Agent as security for all or any part of the Obligations; provided that the
Agent may release Collateral sold in a transaction that has been approved by the
Required Banks if the proceeds of such sale (net of reasonable expenses of sale)
are paid to the Agent, for the ratable benefit of the Banks, in exchange for
such release.

                  Section 9.12. Entire Agreement. This Credit Agreement, the
other Loan Documents and the other documents identified herein or therein
contain the entire agreement between the parties concerning the subject matter
hereof as of the date hereof and supersedes all prior dealings between them with
respect to such subject matter.

                  Section 9.13. Waiver and Release. As a material inducement to
each of the Initial Banks to execute the Transfer Agreement and this Agreement,
the Credit Parties hereby acknowledge that none of them have any unsatisfied
claims or causes of action as of the Closing Date against Bank One under,
pursuant to or by virtue of the Original Agreement, including all prior versions
thereof, and waive and release any and all such claims, rights, causes of action
or demands against Bank One.

                  Section 9.14. Indemnification. The Credit Parties, jointly and
severally, agree to indemnify and hold harmless each of the Banks and the Agent
from and against all liabilities, obligations, losses, damages, penalties,
action, judgments, suits, costs (including attorneys' fees), expenses or
disbursements of any kind whatever which may be imposed upon or asserted against
the Agent or any of the Banks in any way relating to the business operations of
the Credit Parties, their execution of this Credit Agreement or any other of the
Loan Documents or the performance of their obligations thereunder. It is
expressly agreed that neither the Agent nor the Banks shall control the business
activities of the Credit Parties as a result of this Credit Agreement or the
other Loan Documents or the performance thereof.

                  Section 9.15. Interest Rate Hedging Agreement. Each of the
Banks, other than Bank One, may enter into interest rate hedging agreements with
the Company not to exceed the amount of such Bank's Commitment. Bank One may
enter into interest rate hedging agreements, including the Master Agreement with
the Company in excess of its Commitment. Each Bank entering into such an
agreement shall provide notice of such agreement and the amount thereof to the
other Banks within ten (10) days of the execution thereof, provided, however,
that the failure to give such notice timely shall not affect any of the
obligations and liabilities of the Company, then existing or thereafter arising,
under or with respect to the agreement by which the notice was to have been
given, nor preclude such obligations and liabilities from being part of the
Obligations.

                  Section 9.16. Execution. This Agreement may be executed, by
original or facsimile signatures, in two or more counterparts, each of which
shall constitute an original, but all of which when taken together shall
constitute but one agreement.

                  IN WITNESS WHEREOF, the Agent, the Banks and the Credit
Parties have by their duly authorized officers executed this Agreement as of the
date first set forth above.
