NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Texas Industries, Inc. ("TXI" or the "Company"), is a leading supplier of
construction materials through two business segments: cement, aggregate and
concrete products (the "CAC" segment) and structural steel and specialty bar
products (the "Steel" segment). Through the CAC segment, the Company produces
and sells cement, stone, sand and gravel, expanded shale and clay aggregate and
concrete products from facilities concentrated in Texas, Louisiana, and
California, with several products marketed throughout the United States. Through
its Steel segment, the Company produces and sells structural steel, specialty
bar products, merchant bar-quality rounds, reinforcing bar and channels for
markets in North America and, under certain market conditions, Europe and Asia.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the nine-month period ended February 28,
1999, are not necessarily indicative of the results that may be expected for the
year ended May 31, 1999. For further information, refer to the consolidated
financial statements and footnotes thereto included in the Company's annual
report on Form 10-K for the year ended May 31, 1998.

Estimates.  The preparation of financial statements and accompanying notes in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the amounts reported. Actual results
could differ from those estimates.

Principles of Consolidation.  The consolidated financial statements include the
accounts of the Company and all subsidiaries.  The minority interest represents
the separate public ownership of Chaparral Steel Company ("Chaparral"), which
was acquired by the Company on December 31, 1997.  Certain amounts in the prior
period financial statements have been reclassified to conform to the current
period presentation.

Cash Equivalents.  For cash flow purposes, temporary investments which have
maturities of less than 90 days when purchased are considered cash equivalents.

Property, Plant and Equipment. Property, plant and equipment is recorded at
cost. Provisions for depreciation are computed generally using the straight-line
method. Provisions for depletion of mineral deposits are computed on the basis
of the estimated quantity of recoverable raw materials.

Intangible Assets. Goodwill and other intangibles is presented net of
accumulated amortization of $26.6 million at February 28, 1999 and $22.2 million
at May 31, 1998. The final valuation of the fair value of net assets acquired in
the December 31, 1997 purchase of Riverside Cement Company resulted in the
recognition of $7.7 million additional goodwill during the February 1999
quarter. Goodwill resulting from the acquisitions of Chaparral Steel Company and
Riverside Cement Company, totaling $150.2 million at February 28, 1999 and
$145.6 million at May 31, 1998 (net of accumulated amortization), is being
amortized currently on a straight-line basis over 40-year periods. Other
intangibles consisting primarily of goodwill and non-compete agreements are
being amortized on a straight-line basis over periods of 2 to 15 years.
Management reviews remaining goodwill and other intangibles with consideration
toward recovery through future operating results (undiscounted) at the current
rates of amortization.

Income Taxes. The Company joins in filing a consolidated return with its
subsidiaries. Current and deferred tax expense is allocated among the members of
the group based on a stand-alone calculation of the tax of the individual
member.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES-Continued

Earnings Per Share ("EPS"). Basic EPS is computed by adjusting net income for
the amortization of additional goodwill in connection with a contingent payment
for the acquisition of Chaparral, then dividing by the weighted average number
of common shares outstanding during the period including certain contingently
issuable shares. Diluted EPS also adjusts net income for the net dividends on
preferred securities of subsidiary and the outstanding shares for the dilutive
effect of the preferred securities, stock options and awards. The preferred
securities were not included in the computation of diluted EPS for the February
28, 1999 quarter because the effect would have been antidilutive.

Basic and Diluted EPS are calculated as follows:

WORKING CAPITAL

Working capital totaled $262.7 million at February 28, 1999, compared to $227.0
million at May 31, 1998.

Notes and accounts receivable of $143.8 million at February and $151.2 million
at May are presented net of allowances for doubtful receivables of $3.7 million
at February and $3.4 million at May.

On March 11, 1999, the Company entered into an agreement to sell, without
recourse, on a revolving basis, an interest in a deferred pool of trade accounts
receivable of up to $100 million. An initial $85 million interest has been sold
under this agreement with the proceeds used to reduce the amount outstanding
under the Company's revolving credit facility. The Company, as agent for the
purchaser, retains collection and administrative responsibilities for the
participating interests of the deferred pool.

Inventories are summarized as follows:

WORKING CAPITAL-Continued

Inventories are stated at cost (not in excess of market) generally using the
last-in, first-out method (LIFO). If the average cost method (which approximates
current replacement cost) had been used, inventory values would have been higher
by $13.7 million at February and $15.7 million at May.

</TABLE>

Annual maturities of long-term debt for each of the five succeeding years are
$9.3, $9.2, $9.1, $139.0 and $9.0 million.

On March 10, 1999, the Company increased the maximum borrowing limit on its 
bank-financed long-term revolving credit facility from $350 million to $450
million and extended its term until March 2004. In addition to the $130.0
million outstanding under this facility, $69.4 million has been utilized to
support letters of credit. The Company may select at the time of borrowing an
interest rate at either the applicable margin above LIBOR or prime. Commitment
fees at a current annual rate of .125% are paid on the unused portion of this
facility.

On September 22, 1998, the Company issued $50 million variable-rate industrial
development bonds supported by letters of credit issued under the Company's
revolving credit facility. The proceeds reimbursed the Company for costs
incurred in connection with the construction of sewage and solid waste disposal
facilities at the Company's Virginia steel plant. The interest rates on the
bonds closely follow the tax-exempt commercial paper rates.

Loan agreements contain covenants which provide for minimum working capital,
restrictions on purchases of treasury stock and payment of dividends on common
stock, and limitations on incurring certain indebtedness and making certain
investments. Under the most restrictive of these agreements, the aggregate
amount of annual cash dividends on common stock is limited based on the ratio of
earnings before interest, taxes, depreciation and amortization to fixed charges.
The Company is in compliance with all loan covenant restrictions.

The amount of interest paid for the nine-month periods presented was $17.7
million in 1999 and $12.3 million in 1998.  Interest capitalized totaled $15.0
million and $2.1 million in the 1999 and 1998 periods, respectively.

PREFERRED SECURITIES OF SUBSIDIARY

On June 5, 1998, TXI Capital Trust I (the "Trust"), a Delaware business trust
wholly owned by the Company, issued 4,000,000 of its 5.5% Shared Preference
Redeemable Securities ("Preferred Securities") to the public for gross proceeds
of $200 million.  The combined proceeds from the issuance of the Preferred
Securities and the issuance to the Company of the common securities of the Trust
were invested by the Trust in $206.2 million aggregate principal amount of 5.5%
convertible subordinated debentures due June 30, 2028 (the "Debentures") issued
by the Company.  The Debentures are the sole assets of the Trust.

Holders of the Preferred Securities are entitled to receive cumulative cash
distributions at an annual rate of $2.75 per Preferred Security (equivalent to a
rate of 5.5% per annum of the stated liquidation amount of $50 per Preferred
Security). The Company has guaranteed, on a subordinated basis, distributions
and other payments due on the Preferred Securities, to the extent the Trust has
funds available therefor and subject to certain other limitations (the
"Guarantee"). The Guarantee, when taken together with the obligations of the
Company under the Debentures, the Indenture pursuant to which the Debentures
were issued, and the Amended and Restated Trust Agreement of the Trust
(including its obligations to pay costs, fees, expenses, debts and other
obligations of the Trust [other than with respect to the Preferred Securities
and the common securities of the Trust]), provide a full and unconditional
guarantee of amounts due on the Preferred Securities.

The Debentures are redeemable for cash, at the option of the Company, in whole
or in part, on or after June 30, 2001, or under certain circumstances relating
to federal income tax matters, at par, plus accrued and unpaid interest.  Upon
any redemption of the Debentures, a like aggregate liquidation amount of
Preferred Securities will be redeemed.  The Preferred Securities do not have a
stated maturity date, although they are subject to mandatory redemption upon
maturity of the Debentures on June 30, 2028, or upon earlier redemption.

Each Preferred Security is convertible at any time prior to the close of
business on June 30, 2028, at the option of the holder into shares of the
Company's common stock at a conversion rate of .72218 shares of the Company's
common stock for each Preferred Security (equivalent to a conversion price of
$69.235 per share of TXI Common Stock).

There are authorized 100,000 shares of Cumulative Preferred Stock, no par value,
of which 20,000 shares are designated $5 Cumulative Preferred Stock (Voting),
redeemable at $105 per share and entitled to $100 per share upon dissolution. On
March 29, 1996 the Company redeemed and retired all outstanding shares of such
$5 Cumulative Preferred Stock. An additional 25,000 shares are designated Series
B Junior Participating Preferred Stock. The Series B Preferred Stock is not
redeemable and ranks, with respect to the payment of dividends and the
distribution of assets, junior to (i) all other series of the Preferred Stock
unless the terms of any other series shall provide otherwise and (ii) the $5
Cumulative Preferred Stock. Pursuant to a Rights Agreement, in November 1996,
the Company distributed a dividend of one preferred share purchase right for
each outstanding share of the Company's Common Stock. Each right entitles the
holder to purchase from the Company one two-thousandth of a share of the Series
B Junior Participating Preferred Stock at a price of $122.50, subject to
adjustment. The rights will expire on November 1, 2006 unless the date is
extended or the rights are earlier redeemed or exchanged by the Company pursuant
to the Rights Agreement.

STOCK OPTION PLAN

The Company's stock option plan provides that non-qualified and incentive stock
options to purchase Common Stock may be granted to directors, officers and key
employees at market prices at date of grant. Generally, options become
exercisable in installments beginning one year after date of grant and expire
ten years later. A summary of option transactions for the nine-month period

At February 28, 1999, there were 804,573 shares exercisable and 1,630,540 shares
available for future grants. Outstanding options expire on various dates to
January 14, 2009.

INCOME TAXES

Federal income taxes for the interim periods ended February 28, 1999 and 1998,
have been included in the accompanying financial statements on the basis of an
estimated annual rate of 33.1%. The primary reason that the tax rate differs
from the 35% statutory corporate rate is due to goodwill expense which is not
tax deductible, percentage depletion which is tax deductible and the state
income tax expense. The Company made income tax payments of $37.4 million and
$37.2 million in the nine-month periods ended February 28, 1999 and 1998,
respectively.

LEGAL PROCEEDINGS AND CONTINGENT LIABILITIES

The Company is subject to federal, state and local environmental laws and
regulations concerning, among other matters, air emissions, furnace dust
disposal and wastewater discharge. The Company believes it is in substantial
compliance with applicable environmental laws and regulations. Notwithstanding
such compliance, if damage to persons or property or contamination of the
environment has been or is caused by the conduct of the Company's business or by
hazardous substances or wastes used in, generated or disposed of by the Company,
the Company may be held liable for such damages and be required to pay the cost
of investigation and remediation of such contamination. The amount of such
liability could be material. Changes in federal or state laws, regulations or
requirements or discovery of unknown conditions could require additional
expenditures by the Company.

Riverside Cement Company ("Riverside"), acquired by the Company in December
1997, has received a proposed Administrative Order on Consent for De Minimis
Contributors, pursuant to which Riverside would pay the United States
Environmental Protection Agency ("USEPA") $108,788 to settle any legal
responsibilities it may have to the USEPA because of Riverside's disposal of
waste material at times between 1973 and 1989 at the Casmalia Disposal Site in
Santa Barbara County, California, and to obtain protection against contribution
actions by other potentially responsible parties to the USEPA action at the
Site.

The Company and subsidiaries are defendants in lawsuits which arose in the
normal course of business. In management's judgment (based on the opinion of
counsel) the ultimate liability, if any, from such legal proceedings will not
have a material effect on the consolidated financial position of the Company.

                    INDEPENDENT ACCOUNTANTS' REVIEW REPORT



Board of Directors
Texas Industries, Inc.



We have reviewed the accompanying condensed consolidated balance sheet of Texas
Industries, Inc. and subsidiaries as of February 28, 1999, and the related
condensed consolidated statements of income for the three-month and nine-month
periods ended February 28, 1999 and 1998, and the condensed consolidated
statements of cash flows for the nine-month periods ended February 28, 1999 and
1998. These financial statements are the responsibility of the Company's
management.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data, and making inquiries of persons responsible for financial and
accounting matters.  It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, which will be
performed for the full year with the objective of expressing an opinion
regarding the financial statements taken as a whole.  Accordingly, we do not
express such an opinion.

Based on our reviews, we are not aware of any material modifications that should
be made to the accompanying condensed consolidated financial statements referred
to above for them to be in conformity with generally accepted accounting
principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Texas Industries, Inc. and
subsidiaries as of May 31, 1998, and the related consolidated statements of
income, shareholders' equity, and cash flows for the year then ended [not
presented herein] and in our report dated July 15, 1998, we expressed an
unqualified opinion on those consolidated financial statements.  In our opinion,
the information set forth in the accompanying condensed consolidated balance
sheet as of May 31, 1998, is fairly stated, in all material respects, in
relation to the consolidated balance sheet from which it has been derived.

RESULTS OF OPERATIONS

Net Sales.  Consolidated net sales for the current quarter were $252.8 million,
a decline of $28.6 million from the prior year quarter.  Consolidated net sales
for the current nine-month period were $832.3 million, a decline of $28.9
million from the prior year period.  Increased CAC sales only partially offset
the decline in Steel sales.

CAC sales were up from the prior year 39% for the quarter and 41% for the nine
months.  Cement sales increased due primarily to the Company's expansion into
the California cement market through the December 31, 1997 acquisition of
Riverside Cement Company.  Riverside's shipments exceeded the prior year on
comparable average prices.  Sales from the Company's Texas cement plants for the
current quarter were 21% above the prior year quarter on 8% higher shipments and
13% higher average prices.  Texas cement sales for the current nine months were
10% above the prior year period on 12% higher average prices offset by somewhat
lower shipments due to lower cement inventory and production during the first
six months of the year.  Unusually dry weather and continued strong market
conditions in Texas resulted in increased ready-mix and aggregate sales.
Ready-mix sales in the current quarter increased 51% over the prior year period
due to a 33% increase in volume and 14% higher average prices.  Aggregate sales
in the current quarter increased 30% over the prior year period due to a 10%
increase in shipments and 18% higher average prices.

Steel sales were down 40% for the quarter and 31% for the nine months from the
prior year periods.  In the current quarter realized prices declined 17% and
shipments declined 29% from the prior year quarter.  Strong nonresidential
building activity has continued to sustain demand for structural products in
North America, however, an unprecedented increase in structural steel imports
has resulted in a very competitive market.  In January, the Company announced a
12% decrease in wide flange beam prices.  As the Company competes for market
share, prices for structural products could decline further.  The major stage of
the bar mill upgrade project was completed during the November quarter resulting
in lower bar mill production and shipments in the February quarter as the mill
was brought back online.  The remaining stage of the upgrade is scheduled to
occur in the November 1999 quarter.

Operating Costs.  Consolidated cost of products sold including depreciation,
depletion and amortization for the current quarter was $215.7 million, a
decrease of $12.4 million from the prior year quarter.  Costs for the current
nine months were $666.1 million, a decrease of $17.0 million from the prior year
period.  CAC costs increased from the prior year $28.6 million in the quarter
and $91.2 million in the nine months due primarily to the addition of the
Riverside cement plants, higher per unit cement manufacturing costs at the
Company's Texas cement operations, increased ready-mix shipments and higher
aggregate maintenance costs.  Steel costs decreased from the prior year $41.0
million in the quarter and $108.2 million in the nine months due primarily to
lower shipments.

CAC selling, general and administrative expense including depreciation and
amortization increased from the prior year $2.1 million in the quarter and $7.9
million in the nine months due primarily to the expanded cement operations and
higher incentive accruals.  Steel expenses decreased from the prior year $3.4
million in the quarter and $4.7 million in the nine months due to lower
incentive accruals offsetting higher selling expense.

Operating Profit.  Operating profit of $28.1 million for the current quarter and
$124.8 million for the current nine months was $9.6 million lower than the prior
year periods.  CAC operating profit was up 66% for the quarter and up 51% for
the nine months from the prior year periods. The Riverside acquisition
contributed 26% of the increase for the quarter and 48% of the increase for the
nine months.  In the current quarter, ready-mix operations improved on increased
volumes and higher prices.  Aggregate operations in Texas benefited from
increased shipments due to favorable weather that kept sales volume in line with
production.  Increased aggregate pricing was offset by increased manufacturing
costs.  Steel operating profit was lower than the prior year $20.7 million for
the quarter and $47.9 million for the nine months due to reduced shipments and
lower prices.  The profit in the current periods also included $6.3 million in
income from partial settlement of the Company's litigation against certain
graphite electrode suppliers.

Steel profits are being adversely impacted by the unprecedented volume of steel
imports from Russia, Asia and South America.  As an international low-cost
supplier of structural steel products, the Company's focus has shifted from
maximizing margins to maintaining market share, and thus, the Company has
reduced structural beam prices accordingly.  As a result, it is anticipated that
near term unit margins for these products could continue to decline.

Corporate Resources.  Selling, general and administrative expenses including
depreciation and amortization increased from the prior year $1.7 million for the
quarter and $3.5 million for the nine months primarily due to higher incentive
accruals.  Other income for the current quarter was $2.9 million below the prior
year quarter due to lower income from interest and the Company's real estate
operations.

Interest Expense.  Interest expense for the current nine-month period was $10.1
million net of $15.0 million in interest capitalized.  Expense for the prior
year period was $14.4 million net of $2.1 million in interest capitalized.  The
increase of $8.6 million in total interest was the result of increased borrowing
over the past year.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities was $79.8 million, a decrease of $64.6
million from the prior year nine-month period due primarily to changes in
working capital items that was partially offset by higher depreciation,
depletion and amortization expense.  The decline in Steel shipments and prices
reduced receivables and sharply increased inventories.  Accounts payable and
accrued expenses increased in part due to higher interest accruals.  During the
1998 nine-month period receivables grew on increased sales, inventories declined
on increased shipments and accounts payable and accrued expenses increased due
in part to increased trade payables from expanded operations and higher
incentive, interest and tax accruals.

Net cash used by investing activities was $366.4 million compared to $346.4
million during the prior year period, consisting principally of capital
expenditure items.  Historically, capital expenditures have consisted of normal
replacement and technological upgrades of existing equipment and expansion of
the Company's operations.  Expenditures for these activities were $77.6 million
in the current nine-month period.  The fiscal year 1999 capital expenditure
budget is estimated at $90 million, 44% below fiscal year 1998 expenditures.
Additionally, capital expenditures of $385.0 million including $292.3 million in
the current period have been incurred for the construction of the Company's
Virginia steel facility.  Production at this facility is scheduled to begin in
the summer of 1999, with total costs for site, utilities, equipment and
installation estimated to be $450 million.  The Company has received a permit to
expand the production of its Midlothian, Texas cement plant from 1.3 to 2.8
million tons per year.  The $225 million project will include the most advanced
pollution control system ever utilized in a domestic cement plant.  Construction
began in March 1999 with completion expected by the fall of 2000.

Net cash provided by financing activities was $278.0 million, compared to $186.6
million during the prior year period.  On June 5, 1998, TXI Capital Trust I, a
Delaware business trust wholly owned by the Company, issued 4,000,000 of its
5.5% Shared Preference Redeemable Securities ("Preferred Securities") to the
public.  Holders of the Preferred Securities are entitled to receive cumulative
cash distributions at an annual rate of $2.75 per Preferred Security accruing
from the date of issuance and payable quarterly in arrears commencing September
30, 1998.  On September 22, 1998, the Company issued $50 million variable-rate
industrial development bonds supported by letters of credit issued under the
Company's revolving credit facility.  The proceeds reimbursed the Company for
costs incurred in connection with the construction of sewage and solid waste
disposal facilities at the Company's Virginia steel plant.  On March 10, 1999,
Company increased the maximum borrowing limit on its revolving credit facility
from $350 million to $450 million and extended its term until March 2004.  At
February 28, 1999, $130 million was outstanding under the credit facility and an
additional $69.4 million had been utilized to support letters of credit.

                                      -14-

During the current quarter the Company purchased approximately 243,000 shares of
its Common Stock for general corporate purposes.  The Company's quarterly cash
dividend at $.075 per common share remained unchanged from the prior year
period.

On March 11, 1999, the Company entered into an agreement to sell, on a revolving
basis, an interest in a defined pool of trade accounts receivable of up to $100
million.  An initial $85 million interest has been sold under this agreement
with the proceeds used to reduce the amount outstanding under the Company's
revolving credit facility.

The Company generally finances its major capital expansion projects with long-
term borrowing.  Maintenance capital expenditures and working capital are funded
by cash flow from operations.  The Company expects cash from operations and
borrowings under its revolving credit facility to be sufficient to provide funds
for capital expenditure commitments, scheduled debt repayments and working
capital needs during the next two years.

OTHER ITEMS

Litigation. On November 25, 1998, Chaparral Steel Company, a wholly owned
subsidiary, filed an action seeking damages, trebled as allowed by law, plus
interest and costs, in the District Court of Ellis County, Texas against Showa
Denko Carbon, Inc. ("SDC"); Showa Financing, K.K.; Showa Denko, K.K.; The
Carbide/Graphite Group, Inc. ("CGG"); SGL Carbon Aktiengesellschaft; SGL Carbon
Corp.; UCAR Carbon Company, Inc. ("UCAR"), and UCAR International, Inc.
(collectively "Defendants") asserting causes of action for illegal restraints of
trade in the sale of graphite electrodes.  In January 1999, SDC and its
affiliates settled with Chaparral Steel Company and were removed from the
action.  In related criminal actions, two of the Defendants have plead guilty to
criminal violations of the U.S. Antitrust laws and have paid fines; and a third
Defendant has announced that it has agreed to cooperate with the U.S. Department
of Justice investigation into the graphite electrode industry in exchange for
immunity from criminal prosecution for it and some of its executives.  For these
reasons, although the Company's action is still in its preliminary stages, the
Company believes that it should, subject to inherent uncertainties of
litigation, prevail in its claims against the remaining Defendants.

Year 2000 Compliance. Based on an assessment by the Company of its operating,
financial and management information systems, the Company determined that
modification or upgrading certain equipment and software would be necessary to
address Year 2000 issues.  The Company began converting its computerized
business systems in 1992 in order to upgrade system capabilities and utilize
current hardware and software technology.  To date, most systems have been
converted.  Conversion of the remaining systems is expected before December
1999.  The Company is currently addressing the manufacturing process control,
man-machine-interface, and other plant and operational systems and expects to
resolve all material Year 2000 issues before December 1999.

In addition, the Company has contacted its critical suppliers and others to
determine the extent to which the Company would be vulnerable to those third
parties' failure to remediate their own Year 2000 issues.  The Company has
received written assurances from the most critical suppliers and has not been
informed of any material risks associated with other entities.  There can be no
guarantee that the systems of these critical suppliers or other entities on
which the Company relies will be timely converted and would not have an adverse
effect on the Company's systems or operations. Management is currently
developing contingency plans which would attempt to mitigate supplier failures
in these areas. However, due to the dependency on public utilities and
transportation systems, there are limitations to contingent replacements for
these critical resources.

The Company believes that neither the cost of its planned upgrade and
modification program nor a failure to timely complete such program will have a
material impact on the operations or financial condition of the Company.

     Section 2.2   Manner of Borrowing and Disbursement.
                   ------------------------------------ 

     (a)  In the case of Base Rate Advances other than a Refinancing Advance,
the Borrower, through an Authorized Signatory, shall give the Administrative
Lender prior to 10:30 a.m., Dallas, Texas time, on the date of any proposed Base
Rate Advance irrevocable written notice, or irrevocable telephonic notice
followed immediately by written notice (provided, however, that the Borrower's
failure to confirm any telephonic notice in writing shall not invalidate any
notice so given), of its intention to borrow or reborrow a Base Rate Advance
hereunder. Such notice of borrowing shall specify the requested funding date,
which shall be a Business Day, and the amount of the proposed aggregate Base
Rate Advances to be made by Lenders.

     (b)  In the case of LIBOR Advances, the Borrower, through an Authorized
Signatory, shall give the Administrative Lender at least three Business Days'
irrevocable written notice, or irrevocable telephonic notice followed
immediately by written notice (provided, however, that the Borrower's failure to
confirm any telephonic notice in writing shall not invalidate any notice so
given), of its intention to borrow or reborrow a LIBOR Advance hereunder. Notice
shall be given to the Administrative Lender prior to 11:00 a.m., Dallas, Texas
time, in order for such Business Day to count toward the minimum number of
Business Days required. LIBOR Advances shall in all cases be subject to
availability and to Article 9 hereof. For LIBOR Advances, the notice of
borrowing shall specify the requested funding date, which shall be a Business
Day, the amount of the proposed aggregate LIBOR Advances to be made by Lenders
and the Interest Period selected by the Borrower, provided that no such Interest
Period shall extend past the Maturity Date, or prohibit or impair the Borrower's
ability to comply with Section 2.8 hereof.

     (c)  Subject to Sections 2.1 and 2.9 hereof, at least three Business Days
prior to each Payment Date for a LIBOR Advance, the Borrower, through an
Authorized Signatory, shall give the Administrative Lender irrevocable written
notice, or irrevocable telephonic notice followed immediately by written notice
(provided, however, that the Borrower's failure to confirm any telephonic notice
in writing shall not invalidate any notice so given), specifying whether all or
a portion of such LIBOR Advance outstanding on the Payment Date (i) is to be
repaid and then reborrowed in whole or in part as a LIBOR Advance, (ii) is to be
repaid and then reborrowed in whole or in part as a Base Rate Advance, or (iii)
is to be repaid and not reborrowed; provided,

                                      -20-
<PAGE>
 
however, notwithstanding anything in this Agreement to the contrary, if on any
Payment Date a Default shall exist, such LIBOR Advance may only be reborrowed as
a Base Rate Advance. Upon such Payment Date, such LIBOR Advance shall, subject
to the provisions hereof, be so repaid and, as applicable, reborrowed.

     (d) Subject to Sections 2.1 and 2.9 hereof, upon at least two Business
Days' (or at least three Business Days' for a reborrowing as one or more LIBOR
Advances) irrevocable prior written notice, through an Authorized Signatory, or
irrevocable telephonic notice followed immediately by written notice (provided,
however, that the Borrower's failure to confirm any telephonic notice in writing
shall not invalidate any notice so given), the Borrower may repay or prepay a
Base Rate Advance, and (i) reborrow all or a portion of the principal amount
thereof as a Base Rate Advance, (ii) provided no Default shall exist, reborrow
all or a portion of the principal amount thereof as one or more LIBOR Advances,
or (iii) not reborrow all or any portion of such Base Rate Advance. Upon such
Payment Date or date of repayment, such Base Rate Advance shall, subject to the
provisions hereof, be so repaid and, as applicable, reborrowed.

     (e) The aggregate amount of Base Rate Advances to be made by the Lenders on
any day shall be in a principal amount which is at least $500,000 and which is
an integral multiple of $250,000; provided, however, that such amount may equal
the unused amount of the Commitment. The aggregate amount of LIBOR Advances
having the same Interest Period and to be made by the Lenders on any day shall
be in a principal amount which is at least $1,000,000 and which is an integral
multiple of $250,000.

     (f) The Administrative Lender shall promptly notify the Lenders of each
notice (other than with respect to a Bid Rate Advance) received from the
Borrower pursuant to this Section. Failure of the Borrower to give any notice in
accordance with Sections 2.2(c) and (d) hereof shall result in a repayment of
any such existing Revolving Credit Advance on the applicable Payment Date by a
Refinancing Advance which is a Base Rate Advance. Each Lender shall, not later
than noon, Dallas, Texas time, on the date of any Revolving Credit Advance that
is not a Refinancing Advance, deliver to the Administrative Lender, at its
address set forth herein, such Lender's Specified Percentage of such Revolving
Credit Advance in immediately available funds in accordance with the
Administrative Lender's instructions. Prior to 2:00 p.m., Dallas, Texas time, on
the date of any Revolving Credit Advance hereunder, the Administrative Lender
shall, subject to satisfaction of the conditions set forth in Article 3,
disburse the amounts made available to the Administrative Lender by the Lenders
by (i) transferring such amounts by wire transfer pursuant to the Borrower's
instructions, or (ii) in the absence of such instructions, crediting such
amounts to the account of the Borrower maintained with the Administrative
Lender. All Revolving Credit Advances shall be made by each Lender according to
its Specified Percentage. No Lender shall be relieved of its obligation to fund
its Specified Percentage of any Revolving Credit Advance notwithstanding the
fact that at any time the aggregate outstanding principal amount of all Bid Rate
Advances made by such Lender exceed its Specified Percentage of the Commitment.

     (g) Bid Rate Advances. With respect to each borrowing consisting of Bid
         -----------------
Rate Advances, the Borrower shall give the Administrative Lender prior to 11:00
a.m. (Dallas time), (i) in the case of LIBOR Bid Rate Advances, at least four
Business Days prior to the proposed date of borrowing and (ii) in the case of
Absolute Bid Rate Advances, at least three Business Days prior to the proposed

the requested date of borrowing, which shall be a Business Day, (ii) the
aggregate amount of the proposed borrowing of Bid Rate Advances (which shall be
at least $10,000,000 and which is an integral multiple of $1,000,000 in excess
thereof), (iii) the Interest Period with respect thereto, provided that such
Interest Period shall not extend past the Maturity Date, and (iv) whether the
Bid Rate Advances requested are Absolute Bid Rate Advances or LIBOR Bid Rate
Advances.  Bid Rate Advance Requests that do not conform substantially to the
format of Exhibit F may be rejected by the Administrative Lender, and the
          ---------                                                      
Administrative Lender shall give prompt notice to the Borrower of such
rejection.  The Borrower shall pay a $1,000 non-refundable, administrative fee
for the account of the Administrative Lender for each notice of proposed
borrowing consisting of Bid Rate Advances.  Such fee shall be paid to the
Administrative Lender on the date of delivery of the Borrower's notice of
intention to borrow Bid Rate Advances, and shall not be refunded notwithstanding
that the proposed borrowing is canceled by Borrower or no Lender offers to make
a Bid Rate Advance.

         (i)  Upon the receipt by the Administrative Lender of a Bid Rate
     Advance Request that conforms with the requirements herein, the
     Administrative Lender shall, by telecopy in the form of the Invitation to
     Bid, invite each Lender to bid, on the terms and conditions of this
     Agreement, to make Bid Rate Advances pursuant to the Bid Rate Advance
     Request.

         (ii) Each Lender shall, if, in its sole discretion, it elects to do
     so, irrevocably offer to make one or more Bid Rate Advances to the Borrower
     as part of such proposed borrowing at a rate or rates of interest specified
     by such Lender in its sole discretion, by delivering a Confirmation of Bid
     to the Administrative Lender before 11:00 a.m. (Dallas time), (A) three
     Business Days prior to the proposed date of borrowing, in the case of a
     request for LIBOR Bid Rate Advances, and (B) two Business Days prior to the
     proposed date of borrowing, in the case of a request for Absolute Bid Rate
     Advances, (1) setting forth (a) the minimum amount (which shall be
     $1,000,000 or an integral multiple in excess thereof) and maximum amount of
     each Bid Rate Advance which such Lender would be willing to make as part of
     the proposed borrowing (which amounts may exceed such Lender's Specified
     Percentage) and (b) the Absolute Bid Rate or Margin therefor, as 
     applicable, and (2) confirming the Interest Period therefor.  Confirmation
     of Bids that do not conform substantially to Exhibit H may be rejected by
                                                  ---------                   
     the Administrative Lender, and the Administrative Lender shall notify the
     applicable Lender of such rejection as soon as practicable.  If any Lender
     shall fail to respond to the Administrative Lender by such time, such
     Lender shall be deemed to have elected not to make an offer.  Any
     Confirmation of Bid submitted by a Lender pursuant to this Section
     2.2(g)(ii) is irrevocable.

                                      -22-
<PAGE>
 
        (iii)  The Administrative Lender shall promptly notify the Borrower of
     the number of Confirmation of Bids, the interest rate(s) and Interest
     Period(s) applicable thereto, the maximum principal amount bid at each
     interest rate for each Interest Period, and the identity of each Lender
     submitting a Confirmation of Bid.

        (iv)   Not later than 1:00 p.m. (Dallas time) (A) three Business Days
     prior to the proposed date of borrowing in the case of LIBOR Bid Rate
     Advances and (B) two Business Days prior to the proposed date of the
     proposed borrowing in the case of Absolute Bid Rate Advances, the Borrower
     shall, in turn, either

               (A) cancel such proposed borrowing by giving the Administrative
          Lender notice to that effect, or

               (B) accept one or more of the offers made by any Lender or
          Lenders pursuant to clause (ii) above, in its sole discretion, by
          giving notice to the Administrative Lender of the amount of each Bid
          Rate Advance (which amount shall be equal to or greater than the
          minimum amount, and equal to or less than the maximum amount, for
          which notification was given to the Borrower by any Lender for such
          Bid Rate Advance pursuant to clause (ii) above) to be made by each
          Lender as part of such borrowing, and reject any remaining offers made
          by Lenders pursuant to clause (ii) above by giving the Administrative
          Lender notice to that effect; provided, however, that if offers are
          made by two or more such Lenders with the same LIBOR Bid Rates or
          Absolute Bid Rates for a greater aggregate principal amount than the
          amount for which such offers are accepted for the related term, the
          principal amount of Bid Rate Advances accepted shall be allocated by
          the Borrower among such Lenders as nearly as possible (in multiples
          not less than $1,000,000) in proportion to the aggregate principal
          amount of such offers, and (3) the aggregate principal amount of
          offers accepted by the Borrower shall not exceed the maximum amount
          contained in the related Bid Rate Advance Request.

          (v)  The Administrative Lender shall promptly give telephonic notice
     to each bidding Lender if any of its offers have been accepted (and if so,
     in what amount, at what interest rate and for what Interest Period), and
     each successful Lender will thereupon become bound, subject to the other
     applicable conditions hereof, to make each Bid Rate Advance for which its
     offer has been accepted.

          (vi) After completing the notifications referred to in clause (v)
     above, the Administrative Lender shall notify each bidding Lender (A) the
     aggregate amount of Bid Rate Advances made in connection with such proposed
     borrowing, (B) the maturities thereof, and (C) the lowest and highest
     interest rates at which Bid Rate Advances were made for each maturity.

          (vii)  If the Administrative Lender shall at any time elect to submit
     a bid for a Bid Rate Advance in its capacity as a Lender, it shall submit
     such bid directly to the Borrower one-half hour earlier than the latest
     time at which other Lenders are required to submit their bid to the
     Administrative Lender pursuant to Section 2(g)(ii) hereof.

          (viii) If the Borrower accepts one or more offers made by any Lender
     or Lenders pursuant to clause (iv)(B) above, each such Lender shall, unless
     any applicable condition specified in Article 3 hereof has not been
     satisfied, not later than 12:00 noon (Dallas time) on the date of a Bid
     Rate Advance hereunder, make available to the Administrative Lender the
     principal amount of each Bid Rate Advance in immediately available funds,
     to be disbursed by the Administrative Lender by wire transfer pursuant to
     instructions of the Borrower.

     (a)  On Base Rate Advances.
          --------------------- 

          (i)    The Borrower shall pay interest on the outstanding unpaid
     principal amount of each Base Rate Advance, from the date such Advance is
     made until it is due (whether at maturity, by reason of acceleration, by
     scheduled reduction, or otherwise) and repaid, which shall be payable as
     set forth in Section 2.3(a)(ii) hereof, at a simple interest rate per annum
     equal to the Base Rate Basis for such Base Rate Advance as in effect from
     time to time, provided that interest on such Base Rate Advance shall not
     exceed the Maximum Amount.

          (ii)   Interest on each Base Rate Advance shall be computed on the
     basis of a year of 365 or 366 days, as applicable, for the number of days
     actually elapsed, and shall be payable in arrears on each Quarterly Date
     and on the Maturity Date.

     (b)  On LIBOR Advances.
          ----------------- 

          (i)    The Borrower shall pay interest on the unpaid principal amount
     of each LIBOR Advance, from the date such Advance is made until it is due
     (whether at maturity, by reason of acceleration, by scheduled reduction, or
     otherwise) and repaid, at a rate per annum equal to the LIBOR Basis for
     such Advance. The Administrative Lender, whose determination shall be
     conclusive, shall determine the LIBOR Basis on the second Business Day
     prior to the applicable funding date and shall notify the Borrower and the
     Lenders of such LIBOR Basis.

          (ii)   Subject to Section 11.9 hereof, interest on each LIBOR Advance
     shall be computed on the basis of a 360-day year for the actual number of
     days elapsed, and shall be payable in arrears on the applicable Payment
     Date and on the Maturity Date; provided, however, that if the Interest
     Period for such Advance exceeds three months, interest shall 

                                      -24-
<PAGE>
 
     also be due and payable in arrears on the three-month anniversary of the
     beginning of such Interest Period.

     (c)  On Bid Rate Advances.  The Borrower shall pay interest on each 
          --------------------                                           
Absolute Bid Rate Advance at the Absolute Bid Rate offered by the Lender making
such Advance (but not in excess of the Highest Lawful Rate) in arrears on its
Payment Date, and, in addition, if the Interest Period for an Absolute Bid Rate
Advance exceeds 90 days, interest on such Bid Rate Advance shall also be due and
payable on the ninetieth day from the beginning of such Interest Period.
Interest on each Absolute Bid Rate Advance shall be computed on the basis of a
year of 365 or 366 days, as applicable, for the number of days actually elapsed.
The Borrower shall pay interest on each LIBOR Bid Rate Advance at the LIBOR Bid
Rate offered by the Lender making such Advance (but not in excess of the Highest
Lawful Rate) in arrears on its Payment Date, and, in addition, if the Interest
Period for a LIBOR Bid Rate Advance exceeds three months, interest on such LIBOR
Bid Rate Advance shall be due and payable in arrears on the three-month
anniversary of the beginning of such Interest Period. Interest on such LIBOR Bid
Rate Advance shall be computed on the basis of a 360-day year for the actual
number of days elapsed.

     (d)  Interest if No Notice of Selection of Interest Rate Basis.  If the
          ---------------------------------------------------------         
Borrower fails to give the Administrative Lender timely notice of its selection
of a LIBOR Basis or an Interest Period for a LIBOR Advance, or if for any reason
a determination of a LIBOR Basis for any Advance is not timely concluded due to
the fault of the Borrower, the Base Rate Basis shall apply to the applicable
Advance.

     (e)  Interest After an Event of Default.  (i) After an Event of Default 
          ----------------------------------                                 
(other than an Event of Default specified in Section 8.1(f) or (g) hereof) and
during any continuance thereof, at the option of Determining Lenders, and (ii)
after an Event of Default specified in Section 8.1(f) or (g) hereof and during
any continuance thereof, automatically and without any action by the
Administrative Lender or any Lender, the Obligations shall bear interest at a
rate per annum equal to the Default Rate. Such interest shall be payable on the
earlier of demand or the Maturity Date, and shall accrue until the earlier of
(i) waiver or cure (to the satisfaction of the Determining Lenders) of the
applicable Event of Default, (ii) agreement by the Lenders to rescind the
charging of interest at the Default Rate, or (iii) payment in full of the
Obligations. The Lenders shall not be required to accelerate the maturity of the
Advances, to exercise any other rights or remedies under the Loan Documents, or
to give notice to the Borrower of the decision to charge interest at the Default
Rate. The Lenders will undertake to notify the Borrower, after the effective
date, of the decision to charge interest at the Default Rate.

     (d)  Prepayments, Generally.  With respect to mandatory prepayments, the
          ----------------------                                             
Borrower shall first prepay all Base Rate Advances and shall thereafter prepay
LIBOR Advances.  To the extent that any prepayment requires that a LIBOR Advance
be repaid on a date other than the last day of its Interest Period, the Borrower
shall reimburse each Lender in accordance with Section 2.9 hereof.  Any
prepayment of a LIBOR Advance shall be accompanied by interest accrued on the
principal amount being prepaid.  Any voluntary partial prepayment of a Base Rate
Advance shall be in a principal amount of $100,000 or an integral multiple
thereof.

     Section 2.6  Reduction of Commitment.
                  ----------------------- 

     (a)  Voluntary Reduction.  The Borrower shall have the right, upon not less
          -------------------                                                   
than 10 Business Days' notice (provided no notice shall be required for a
termination in whole of the Commitment) by an Authorized Signatory to the
Administrative Lender (if telephonic, to be confirmed by telex or in writing on
or before the date of reduction or termination), which shall promptly notify the
Lenders, to terminate or reduce the Commitment, in whole or in part.  Each
partial termination shall be in an aggregate amount which is at least $5,000,000
and which is an integral multiple of $100,000, and no voluntary reduction in the
Commitment shall cause any LIBOR Advance to be repaid prior to the last day of
its Interest Period.

     (b)  Mandatory Reduction.  The Commitment shall be automatically reduced by
          -------------------                                                   
the amount of Net Cash Proceeds received from the sale or disposition by the
Borrower or any Subsidiary of any equity interest in any Venture.  On the
Maturity Date, the Commitment shall automatically reduce to zero.

     (c)  General Requirements.  The Borrower shall reimburse each Lender for 
          --------------------                                                
any loss or out-of-pocket expense incurred by each Lender in connection with any
prepayment pursuant to Section 2.5 hereof, as set forth in Section 2.9 hereof to
the extent applicable.  The Borrower shall 

                                      -27-
<PAGE>
 
not have any right to rescind any termination or reduction. Once reduced, the
Commitment may not be increased or reinstated.

     Section 2.7  Non-Receipt of Funds by the Administrative Lender.  Unless the
                  -------------------------------------------------             
Administrative Lender shall have been notified by a Lender prior to the date of
any proposed Revolving Credit Advance (which notice shall be effective upon
receipt) that such Lender does not intend to make the proceeds of such Revolving
Credit Advance available to the Administrative Lender, the Administrative Lender
may assume that such Lender has made such proceeds available to the
Administrative Lender on such date, and the Administrative Lender may in
reliance upon such assumption (but shall not be required to) make available to
the Borrower a corresponding amount.  If such corresponding amount is not in
fact made available to the Administrative Lender by such Lender, the
Administrative Lender shall be entitled to recover such amount on demand from
such Lender (or, if such Lender fails to pay such amount forthwith upon such
demand, from the Borrower) together with interest thereon in respect of each day
during the period commencing on the date such amount was available to the
Borrower and ending on (but excluding) the date the Administrative Lender
receives such amount from the Lender, with interest thereon at a per annum rate
equal to the lesser of (i) the Highest Lawful Rate or (ii) the Federal Funds
Rate.  No Lender shall be liable for any other Lender's failure to fund a
Revolving Credit Advance hereunder.

     Section 2.8  Payment of Principal of Advances.  The Borrower agrees to 
                  --------------------------------                          
pay the principal amount of the Advances to the Administrative Lender for the
account of the Lenders, as applicable, as follows:

     (a)  Base Rate Advances.  The unpaid principal amount of the Base Rate
          ------------------                                               
Advances shall be due and payable on the applicable Maturity Date.

     (b)  LIBOR Advances.  The principal amount of each LIBOR Advance hereunder
          --------------                                                       
shall be due and payable on its Payment Date, which principal payment may be
made by means of a Refinancing Advance.

     (c)  Bid Rate Advances.  The principal amount of each Bid Rate Advance 
          -----------------                                                 
shall be due and payable on its Payment Date.

     (d)  Commitment Reduction.  On the date of each reduction of the Commitment
          --------------------                                                  
pursuant to Section 2.6 hereof, including the Maturity Date, the aggregate
amount of the Advances outstanding on such date of reduction in excess of the
Commitment as reduced minus all outstanding Reimbursement Obligations shall be
due and payable, which principal payment may not be made by means of Refinancing
Advances.  On the Maturity Date, the Commitment shall be reduced to zero.

     (e)  Maturity Date.  The principal amount of the Advances, all accrued
          -------------                                                    
interest and fees thereon, and all other Obligations related thereto, shall be
due and payable in full on the Maturity Date.

     Section 2.9  Reimbursement.  Whenever any Lender shall sustain or incur any
                  -------------                                                 
losses or reasonable out-of-pocket expenses in connection with (a) failure by
the Borrower to borrow any LIBOR Advance or Bid Rate Advance after having given
notice of its intention to borrow in accordance with Section 2.2 hereof (whether
by reason of the Borrower's election not to proceed or the non-fulfillment of
any of the conditions set forth in Article 3 hereof), (b) any prepayment for any
reason of any LIBOR Advance or Bid Rate Advance in whole or in part (including a
prepayment pursuant to Sections 2.5(c) and 9.3(b) hereof), or (c) any prepayment
of any LIBOR Advance that is not made on any date specified in a notice of
prepayment given by the Borrower, the Borrower agrees to pay to any such Lender,
upon its demand, an amount sufficient to compensate such Lender for all such
losses and out-of-pocket expenses, subject to Section 11.9 hereof.  Such
Lender's good faith determination of the amount of such losses or out-of-pocket
expenses, calculated in its usual fashion, absent manifest error, shall be
binding and conclusive.  Such losses shall include, without limiting the
generality of the foregoing, lost profits and reasonable expenses incurred by
such Lender in connection with the re-employment of funds prepaid, repaid,
converted or not borrowed, converted or paid, as the case may be.  Upon request
of the Borrower, such Lender shall provide a certificate setting forth the
amount to be paid to it by the Borrower hereunder and calculations therefor.

     Section 2.10 Manner of Payment.
                  ----------------- 

     (a)  Each payment (including prepayments) by the Borrower of the principal
of or interest on the Advances, fees, and any other amount owed under this
Agreement or any other Loan Document shall be made not later than 12:00 noon
(Dallas, Texas time) on the date specified for payment under this Agreement to
the Administrative Lender at the Administrative Lender's office, in lawful money
of the United States of America constituting immediately available funds.

     (b)  If any payment under this Agreement or any other Loan Document shall
be specified to be made upon a day which is not a Business Day, it shall be made
on the next succeeding day which is a Business Day, unless such Business Day
falls in another calendar month, in which case payment shall be made on the
preceding Business Day. Any extension of time shall in such case be included in
computing interest and fees, if any, in connection with such payment.

     (c)  The Borrower agrees to pay principal, interest, fees and all other
amounts due under the Loan Documents without deduction for set-off or
counterclaim or any deduction whatsoever.

     (d)  If some but less than all amounts due from the Borrower are received
by the Administrative Lender, the Administrative Lender shall apply such amounts
in the following order of priority: (i) to the payment of the Administrative
Lender's expenses incurred on behalf of the Lenders then due and payable, if
any; (ii) to the payment of all other fees then due and payable; (iii) to the
payment of interest then due and payable on the Advances and the Reimbursement
Obligations; (iv) to the payment of all other amounts not otherwise referred to
in this clause (d) then due and payable under the Loan Documents; and (v) to the
payment of principal then due and

                                      -29-
<PAGE>
 
payable on the Advances and the Reimbursement Obligations, and in the case of
any payments under any Subsidiary Guaranty, to pay any other obligations to any
Guarantied Party (as defined in the Subsidiary Guaranty) not covered in clauses
(i) through (iv) above, ratably among the Guarantied Parties in accordance with
the aggregate principal amount of Advances and Reimbursement Obligations and, in
the case of payments under any Subsidiary Guaranty, the obligations guaranteed
thereby, owed to each Guarantied Party.

     (e)  Except as otherwise provided in the last sentence of this Section
2.10(e), each payment by the Borrower in respect of obligations relating to the
Revolving Credit Advances and the Letters of Credit (whether for principal,
interest, fees or otherwise) shall, except as otherwise expressly provided
herein, be made to the Administrative Lender for the account of the Lenders pro
rata in accordance with their respective Specified Percentages.  Except as
otherwise provided in the last sentence of this Section 2.10(e), each payment by
the Borrower in respect of obligations relating to the Bid Rate Advances shall
be made to the Administrative Lender for the account of the Lenders making such
Bid Rate Advances.  Notwithstanding anything in this Section 2.10(e) or any
other provision of this Agreement or any other Loan Document to the contrary,
any payment by the Borrower in respect of any Advances after acceleration of the
Advances pursuant to Section 8.2 or any monies received by the Administrative
Lender as a result of the exercise of remedies under any Loan Documents after
acceleration of Advances pursuant to Section 8.2 shall be distributed pro rata
to each Lender based on the percentage that the outstanding Advances and
Reimbursement Obligations owed to such Lender bears to the aggregate Advances
and Reimbursement Obligations owed to all Lenders.

     Section 2.11 LIBOR Lending Offices.  Each Lender's initial LIBOR Lending
                  ---------------------

                                         ----------                       
Lender shall have the right at any time and from time to time to designate a
different office of itself or of any Affiliate as such Lender's LIBOR Lending
Office, and to transfer any outstanding LIBOR Advance to such LIBOR Lending
Office.  No such designation or transfer shall result in any liability on the
part of the Borrower for increased costs or expenses resulting solely from such
designation or transfer (except any such transfer which is made by a Lender
pursuant to Section 9.2 or 9.3 hereof, or otherwise for the purpose of complying
with Applicable Law).  Increased costs for expenses resulting from a change in
law occurring subsequent to any such designation or transfer shall be deemed not
to result solely from such designation or transfer.

     Section 2.12 Sharing of Payments.  Any Lender obtaining a payment (whether
                  -------------------                                          
voluntary or involuntary, due to the exercise of any right of set-off, or
otherwise) on account of its Revolving Credit Advances in excess of its
Specified Percentage of all payments made by the Borrower with respect to
Revolving Credit Advances shall purchase from each other Lender such
participation in the Revolving Credit Advances made by such other Lender as
shall be necessary to cause such purchasing Lender to share the excess payment
pro rata according to Specified Percentages with each other Lender; provided,
however, that if all or any portion of such excess payment is thereafter
recovered from such purchasing Lender, the purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest.
The Borrower agrees that any Lender 

                                      -30-
<PAGE>
 
so purchasing a participation from another Lender pursuant to this Section, to
the fullest extent permitted by law, may exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such
participation.

     Section 2.13  Calculation of LIBOR Rate. The provisions of this Agreement
                   -------------------------                                   
relating to calculation of the LIBOR Rate are included only for the purpose of
determining the rate of interest or other amounts to be paid hereunder that are
based upon such rate, it being understood that each Lender shall be entitled to
fund and maintain its funding of all or any part of a LIBOR Advance as it sees
fit.

     Section 2.14  Booking Loans. Any Lender may make, carry or transfer
                   -------------

any Affiliate.

     Section 2.15  Taxes.
                   ----- 

     (a)  Any and all payments by the Borrower hereunder shall be made, in
accordance with Section 2.10, free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges and
withholdings, and all liabilities with respect thereto, excluding, in the case
                                                        ---------             
of each Lender and the Administrative Lender, taxes imposed on, based upon or
measured by its overall net income, net worth or capital, and franchise taxes,
doing business taxes or minimum taxes imposed on it, (i) by the jurisdiction
under the laws of which such Lender or the Administrative Lender (as the case
may be) is organized and in which it has its applicable lending office or any
political subdivision thereof; (ii) by any other jurisdiction, or any political
subdivision thereof, other than those imposed by reason of (A) an asserted
relation of such jurisdiction to the transactions contemplated by this
Agreement, (B) the activities of the Borrower in such jurisdiction, or (C) the
activities in connection with the transactions contemplated by this Agreement of
a Lender or the Administrative Lender; (iii) by reason of failure by the Lender
or the Administrative Lender to comply with the requirements of paragraph (e) of
this Section 2.15; and (iv) in the case of any Lender, any Taxes in the nature
of transfer, stamp, recording or documentary taxes resulting from a transfer
(other than as a result of foreclosure) by such Lender of all or any portion of
its interest in this Agreement, the Notes or any other Loan Documents (all such
non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be
                                              -----                             
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to any Lender or the Administrative Lender, (x) the sum payable shall
be increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.15) such Lender or the Administrative Lender (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made,
(y) the Borrower shall make such deductions and (z) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

                                      -31-

     (b)  In addition, the Borrower agrees to pay any and all stamp and
documentary taxes and any and all other excise and property taxes, charges and
similar levies (other than Taxes described in clause (iv) of the first sentence
of Section 2.15(a)) that arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Document (hereinafter referred to as "Other Taxes").
                                                                  -----------   

     (c)  The Borrower will indemnify each Lender and the Administrative Lender
for the full amount of Taxes and Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.15) paid by such Lender or the Administrative Lender (as the case may
be) and all liabilities (including penalties, additions to tax, interest and
reasonable expenses) arising therefrom or with respect thereto whether or not
such Taxes or Other Taxes were correctly or legally asserted, other than
penalties, additions to tax, interest and expenses arising as a result of gross
negligence on the part of such Lender or the Administrative Lender, provided,
                                                                    -------- 
however, that the Borrower shall have no obligation to indemnify such Lender or
- -------                                                                        
the Administrative Lender unless and until such Lender or the Administrative
Lender shall have delivered to the Borrower a certificate setting forth in
reasonable detail the basis of the Borrower's obligation to indemnify such
Lender or the Administrative Lender pursuant to this Section 2.15. This
indemnification shall be made within 30 days from the date such Lender or the
Administrative Lender (as the case may be) makes written demand therefor.

     (d)  Within 30 days after the date of any payment of Taxes, the Borrower
will furnish to the Administrative Lender the original or a certified copy of a
receipt evidencing payment thereof. If no Taxes are payable in respect of any
payment hereunder, the Borrower will furnish to the Administrative Lender a
certificate from each appropriate taxing authority, or an opinion of counsel
acceptable to the Administrative Lender, in either case stating that such
payment is exempt from or not subject to Taxes, provided, however, that such
                                                --------  -------           
certificate or opinion need only be given if: (i) the Borrower makes any payment
from any account located outside the United States, or (ii) the payment is made
by a payor that is not a United States Person. For purposes of this Section 2.15
the terms "United States" and "United States Person" shall have the meanings set
           -------------       --------------------                
forth in Section 7701 of the Code.

     (e)  Each Lender which is not a United States Person hereby agrees that:

          (i)  it shall, no later than the Agreement Date (or, in the case of a
     Lender which becomes a party hereto pursuant to Section 11.6 after the
     Agreement Date, the date upon which such Lender becomes a party hereto)
     deliver to the Borrower through the Administrative Lender, with a copy to
     the Administrative Lender:

               (A)  if any lending office is located in the United States of
       America, two (2) accurate and complete signed originals of Internal
       Revenue Service Form 4224 or any successor thereto ("Form 4224"),
                                                            ---------

<PAGE>
 
                 (B)  if any lending office is located outside the United States
          of America, two (2) accurate and complete signed originals of Internal
          Revenue Service Form 1001 or any successor thereto ("Form 1001").
                                                               ---------   
          
     in each case indicating that such Lender is on the date of delivery thereof
     entitled to receive payments of principal, interest and fees for the
     account of such lending office or lending offices under this Agreement free
     from withholding of United States Federal income tax;

          (ii)   if at any time such Lender changes its lending office or
     lending offices or selects an additional lending office it shall, at the
     same time or reasonably promptly thereafter but only to the extent the
     forms previously delivered by it hereunder are no longer effective, deliver
     to the Borrower through the Administrative Lender, with a copy to the
     Administrative Lender, in replacement for the forms previously delivered by
     it hereunder:

                 (A)  if such changed or additional lending office is located in
          the United States of America, two (2) accurate and complete signed
          originals of Form 4224; or

                 (B)  otherwise, two (2) accurate and complete signed originals
          of Form 1001,

     in each case indicating that such Lender is on the date of delivery thereof
     entitled to receive payments of principal, interest and fees for the
     account of such changed or additional lending office under this Agreement
     free from withholding of United States Federal income tax;

          (iii)  it shall, before or promptly after the occurrence of any event
     (including the passing of time but excluding any event mentioned in clause
     (ii) above) requiring a change in the most recent Form 4224 or Form 1001
     previously delivered by such Lender and if the delivery of the same be
     lawful, deliver to the Borrower through the Administrative Lender with a
     copy to the Administrative Lender, two (2) accurate and complete original
     signed copies of Form 4224 or Form 1001 in replacement for the forms
     previously delivered by such Lender;

          (iv)   it shall, promptly upon the request of the Borrower to that
     effect, deliver to the Borrower such other forms or similar documentation
     as may be required from time to time by any applicable law, treaty, rule or
     regulation in order to establish such Lender's tax status for withholding
     purposes; and

          (v)    it shall notify the Borrower within 30 days after any event
     (including an amendment to, or a change in any applicable law or regulation
     or in the written interpretation thereof by any regulatory authority or any
     judicial authority, or by ruling applicable to such Lender of any
     governmental authority charged with the interpretation or administration of
     any law) shall occur that results in such Lender no longer being capable of
     receiving payments without any deduction or withholding of United States
     federal income tax.

     (f)  Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 2.15 shall survive the payment in full of principal and interest
hereunder.

     (g)  Any Lender claiming any additional amounts payable pursuant to this
Section 2.15 shall use its reasonable best efforts (consistent with its internal
policy and legal and regulatory restrictions) to change the jurisdiction of its
lending office, if the making of such a change would avoid the need for, or
reduce the amount of, any such additional amounts which may thereafter accrue
and would not, in the reasonable judgment of such Lender, be materially
disadvantageous to such Lender.

     (h)  Each Lender (and the Administrative Lender with respect to payments to
the Administrative Lender for its own account) agrees that (i) it will take all
reasonable actions by all usual means to maintain all exemptions, if any,
available to it from United States withholding taxes (whether available by
treaty, existing administrative waiver, by virtue of the location of any
Lender's lending office) and (ii) otherwise cooperate with the Borrower to
minimize amounts payable by the Borrower under this Section 2.15; provided,
                                                                  -------- 
however, the Lenders and the Administrative Lender shall not be obligated by
- -------                                                                     
reason of this Section 2.15(h) to contest the payment of any Taxes or Other
Taxes or to disclose any information regarding its tax affairs or tax
computations or reorder its tax or other affairs or tax or other planning.
Subject to the foregoing, to the extent the Borrower pays sums pursuant to this
Section 2.15 and the Lender or the Administrative Lender receives a refund of
any or all of such sums, such refund shall be applied to pay any amounts then
due and owing under this Agreement or, to the extent that no amounts are due and
owing under this Agreement at the time such refunds are received, the party
receiving such refund shall promptly pay over all such refunded sums to the
Borrower, provided that no Default or Event of Default is in existence at such
time.

Issuing Bank shall, if so requested, issue, letters of credit (the "Letters of

any Business Day from the date of the initial Advance until the Maturity Date in
an aggregate maximum amount (assuming compliance with all conditions to drawing)
not to exceed at any time outstanding the lesser of (i) $175,000,000 (the
"Letter of Credit Facility") and (ii) the sum of (A) the Commitment minus (B)

money. No Letter of Credit (other than the Tax-Exempt Letters of Credit) shall
have an expiration date (including all rights of renewal) later than the earlier
of (i) ten days prior to the Maturity Date or (ii) one year after the date of
issuance thereof. Immediately upon the issuance of each Letter of Credit (or,

Issuing Bank

                                      -34-
<PAGE>
 
shall be deemed to have sold and transferred to each Lender, and each Lender
shall be deemed to have purchased and received from the Issuing Bank, in each
case irrevocably and without any further action by any party, an undivided
interest and participation in such Letter of Credit, each drawing thereunder and
the obligations of the Borrower under this Agreement in respect thereof in an
amount equal to the product of (x) such Lender's Specified Percentage of the
Commitment times (y) the maximum amount available to be drawn under such Letter
of Credit (assuming compliance with all conditions to drawing). Within the
limits of the Letter of Credit Facility, and subject to the limits referred to
above, the Borrower may request the issuance of Letters of Credit under this
Section 2.16(a), repay any Advances resulting from drawings thereunder pursuant
to Section 2.16(c) and request the issuance of additional Letters of Credit
under this Section 2.16(a).

     (b)  Request for Issuance. Each Letter of Credit shall be issued upon
          --------------------                                             
notice, given not later than 11:00 a.m. (Dallas time) on the third Business Day
prior to the date of the proposed issuance of such Letter of Credit, by the
Borrower to the Issuing Bank, which shall give to the Administrative Lender and
each Lender prompt notice thereof by telex, telecopier or cable. Each Letter of
Credit shall be issued upon notice given in accordance with the terms of any
separate agreement between the Borrower (and, if such Letter of Credit is being
issued for the account of a Subsidiary, such Subsidiary) and the Issuing Bank in
form and substance reasonably satisfactory to the Borrower (and, if such Letter
of Credit is being issued for the account of a Subsidiary, such Subsidiary) and
the Issuing Bank providing for the issuance of Letters of Credit pursuant to
this Agreement and containing terms and conditions not inconsistent with this
Agreement (a "Letter of Credit Agreement"), provided that if any such terms and
              --------------------------    --------                           
conditions are inconsistent with this Agreement, this Agreement shall control.
Each such notice of issuance of a Letter of Credit (a "Notice of Issuance")
                                                       ------------------  
shall be by telex, telecopier or cable, specifying therein, in the case of a
Letter of Credit, the requested (A) date of such issuance (which shall be a
Business Day), (B) maximum amount of such Letter of Credit, (C) expiration date
of such Letter of Credit, (D) name and address of the beneficiary of such Letter
of Credit, (E) form of such Letter of Credit and (F) such other information as
shall be required pursuant to the relevant Letter of Credit Agreement. If the
requested terms of such Letter of Credit are acceptable to the Issuing Bank in
its reasonable discretion, the Issuing Bank will, upon fulfillment of the
applicable conditions set forth in Article 3 hereof, make such Letter of Credit
available to the Borrower (or, if such Letter of Credit is being issued for the
account of a Subsidiary, to such Subsidiary) at its office referred to in
Section 11.1 or as otherwise agreed with the Borrower (or, if such Letter of
Credit is being issued for the account of a Subsidiary, to such Subsidiary) in
connection with such issuance.

     (c)  Drawing and Reimbursement. The payment by the Issuing Bank of a draft
          -------------------------                                             
drawn under any Letter of Credit shall constitute for all purposes of this
Agreement the making by the Issuing Bank of a Revolving Credit Advance, which
shall bear interest at the Base Rate Basis, in the amount of such draft (but
without any requirement for compliance with the conditions set forth in Article
3 hereof). In the event that a drawing under any Letter of Credit is not
reimbursed by the Borrower by 11:00 a.m. (Dallas time) on the first Business Day
after such drawing, the Issuing Bank shall promptly notify Administrative Lender
and each other Lender. Each such Lender shall, on the first Business Day
following such notification, make a Revolving Credit Advance (or if as a result

                                      -35-
<PAGE>
 
of any Debtor Relief Law the Lenders are prohibited from making a Revolving
Credit Advance, each Lender shall fund its participation purchased pursuant to
Section 2.16(a) by making such amount available to the Administrative Lender),
which shall bear interest at the Base Rate Basis, and shall be used to repay the
applicable portion of the Issuing Bank's Revolving Credit Advance with respect
to such Letter of Credit, in an amount equal to the amount of its participation
in such drawing for application to reimburse the Issuing Bank (but without any
requirement for compliance with the applicable conditions set forth in Article 3
hereof) and shall make available to the Administrative Lender for the account of
the Issuing Bank, by deposit at the Administrative Lender's office, in same day
funds, the amount of such Revolving Credit Advance (or such participation). In
the event that any Lender fails to make available to the Administrative Lender
for the account of the Issuing Bank the amount of such Revolving Credit Advance
(or such participation), the Issuing Bank shall be entitled to recover such
amount on demand from such Lender together with interest thereon at a rate per
annum equal to the lesser of (i) the Highest Lawful Rate or (ii) the Federal
Funds Rate.

     (d)  Increased Costs. If any change in any law or regulation or in the
          ---------------                                                   
interpretation thereof by any court or administrative or governmental authority
charged with the administration thereof shall either (i) impose, modify or deem
applicable any reserve, special deposit or similar requirement against letters
of credit or guarantees issued by, or assets held by, or deposits in or for the
account of, the Issuing Bank or any Lender or (ii) impose on the Issuing Bank or
any Lender or any corporation controlling the Issuing Bank or any Lender any
other condition regarding this Agreement or such Lender or any Letter of Credit,
and the result of any event referred to in the preceding clause (i) or (ii)
shall be to increase the cost to the Issuing Bank of issuing or maintaining any
Letter of Credit or to any Lender of purchasing any participation therein or
making any Revolving Credit Advance pursuant to Section 2.16(c), then, upon
demand by the Issuing Bank or such Lender, the Borrower shall, subject to
Section 11.9 hereof, pay to the Issuing Bank or such Lender, from time to time
as specified by the Issuing Bank or such Lender, additional amounts that shall
be sufficient to compensate the Issuing Bank or such Lender for such increased
cost. A certificate as to the amount of such increased cost, submitted to the
Borrower by the Issuing Bank or such Lender, shall include in reasonable detail
the basis for the demand for additional compensation and shall be conclusive and
binding for all purposes, absent manifest error. The obligations of the Borrower
under this Section 2.16(d) shall survive termination of this Agreement. The
Issuing Bank or any Lender claiming any additional compensation under this
Section 2.16(d) shall use reasonable efforts (consistent with legal and
regulatory restrictions) to reduce or eliminate any such additional compensation
which may thereafter accrue and which efforts would not, in the sole discretion
of the Issuing Bank or such Lender, be otherwise disadvantageous.

     (e)  Obligations Absolute. The obligations of the Borrower under this
          --------------------                                             
Agreement with respect to any Letter of Credit, any Letter of Credit Agreement

Letter of Credit Agreement and such other agreement or instrument under all
circumstances, including, without limitation, the following circumstances:

     or any other agreement or instrument relating thereto (collectively, the
     "L/C Related Documents");
      ---------------------   

          (ii)   any change in the time, manner or place of payment of, or in
     any other term of, all or any of the Obligations of the Borrower in respect
     of the Letters of Credit or any Revolving Credit Advance pursuant to
     Section 2.16(c) or any other amendment or waiver of or any consent to
     departure from all or any of the L/C Related Documents;

          (iii)  the existence of any claim, set-off, defense or other right
     that the Borrower may have at any time against any beneficiary or any

     Lender or any other Person, whether in connection with this Agreement, the
     transactions contemplated hereby or by the L/C Related Documents or any
     unrelated transaction;

     Credit proving to be forged, fraudulent, invalid or insufficient in any
     respect or any statement therein being untrue or inaccurate in any respect;

          (v)    payment by the Issuing Bank under a Letter of Credit against
     presentation of a draft or certificate that does not comply with the terms
     of the Letter of Credit, except for any payment made upon the Issuing
     Bank's gross negligence or willful misconduct;

          (vi)   any exchange, release or non-perfection of any collateral, or
     any release or amendment or waiver of or consent to departure from any

     Obligations of the Borrower in respect of the Letters of Credit or any
     Revolving Credit Advance pursuant to Section 2.16(c); or

          (vii)  any other circumstance or happening whatsoever, whether or not
     similar to any of the foregoing, including, without limitation, any other
     circumstance that might otherwise constitute a defense available to, or a
     discharge of, the Borrower or a guarantor, other than the Issuing's Bank
     gross negligence or wilful misconduct.

of any other action by the Administrative Lender or any Lender), the Borrower

                                                     -------------------
Account").
- -------

     (ii)   As security for the payment of all Reimbursement Obligations and for
any other Obligations, the Borrower hereby grants, conveys, assigns, pledges,
sets over and transfers to the Administrative Lender (for the benefit of the
Issuing Bank and Lenders), and

                                      -38-

creates in the Administrative Lender's favor (for the benefit of the Issuing
Bank and Lenders) a Lien in, all money, instruments and securities at any time
held in or acquired in connection with the L/C Cash Collateral Account, together
with all proceeds thereof. The L/C Cash Collateral Account shall be under the
sole dominion and control of the Administrative Lender and the Borrower shall
have no right to withdraw or to cause the Administrative Lender to withdraw any
funds deposited in the L/C Cash Collateral Account. At any time and from time to
time, upon the Administrative Lender's request, the Borrower promptly shall
execute and deliver any and all such further instruments and documents,
including UCC financing statements, as may be necessary, appropriate or
desirable in the Administrative Lender's judgment to obtain the full benefits
(including perfection and priority) of the security interest created or intended
to be created by this paragraph (ii) and of the rights and powers herein
granted. The Borrower shall not create or suffer to exist any Lien on any
amounts or investments held in the L/C Cash Collateral Account other than the
Lien granted under this paragraph (ii) and Liens arising by operation of Law and
not by contract which secure amounts not yet due and payable.

     (iii)  The Administrative Lender shall (A) apply any funds in the L/C Cash
Collateral Account on account of Reimbursement Obligations when the same become
due and payable if and to the extent that the Borrower shall fail directly to
pay such Reimbursement Obligations and (B) after the Maturity Date, apply any
proceeds remaining in the L/C Cash Collateral Account first to pay any unpaid
                                                      -----
Obligations then outstanding hereunder and then to refund any remaining amount

     (iv)   The Borrower, no more than once in any calendar month, may direct
the Administrative Lender to invest the funds held in the L/C Cash Collateral
Account (so long as the aggregate amount of such funds exceeds any relevant
minimum investment requirement) in (A) direct obligations of the United States
or any agency thereof, or obligations guaranteed by the United States or any
agency thereof and (B) one or more other types of investments permitted by the
Determining Lenders, in each case with such maturities as the Borrower, with the
consent of the Determining Lenders, may specify, pending application of such
funds on account of Reimbursement Obligations or on account of other
Obligations, as the case may be. In the absence of any such direction from the
Borrower, the Administrative Lender shall invest the funds held in the L/C Cash
Collateral Account (so long as the aggregate amount of such funds exceeds any
relevant minimum investment requirement) in one or more types of investments
with the consent of the Determining Lenders with such maturities as the
Borrower, with the consent of the Determining Lenders, may specify, pending
application of such funds on account of Reimbursement Obligations or on account
of other Obligations, as the case may be. All such investments shall be made in
the Administrative Lender's name for the account of the Lenders. The Borrower
recognizes that any losses or taxes with respect to such investments shall be
borne solely by the Borrower, and the Borrower agrees to hold the Administrative
Lender and the Lenders harmless from any and all such losses and taxes.
Administrative Lender may liquidate any investment held in the L/C Cash
Collateral Account in order to

                                      -39-
<PAGE>
 
     apply the proceeds of such investment on account of the Reimbursement
     Obligations (or on account of any other Obligation then due and payable, as
     the case may be) without regard to whether such investment has matured and
     without liability for any penalty or other fee incurred (with respect to
     which the Borrower hereby agrees to reimburse the Administrative Lender) as
     a result of such application.

          (v)  The Borrower shall pay to the Administrative Lender the fees
     customarily charged by the Issuing Bank with respect to the maintenance of
     accounts similar to the L/C Cash Collateral Account.

     (e)  The Administrative Lender shall have received all such other
certificates, reports, statements, opinions of counsel or other documents as the
Administrative Lender or any Lender may reasonably request.

     Notwithstanding the above, the obligation of each Lender to make a
Revolving Credit Advance pursuant to Section 2.16(c) (or fund its participation
in respect of Letters of Credit pursuant to Section 2.16(c)) shall be absolute
and unconditional and shall not be affected by any circumstances, including,
without limitation, (i) the occurrence of any Default or Event of Default, or
(ii) the failure of the Borrower to satisfy any condition set forth in this
Section 3.2; provided, however, the conditions precedent set forth in Sections
             --------  -------                                                
3.1 and 3.2 hereof with respect to the Letter of Credit for which such Revolving
Credit Advance is made (or participation funded) shall have been satisfied in
full at the time of issuance of such Letter of Credit.

     Each request by the Borrower to the Administrative Lender or the Issuing
Bank, as appropriate, for an Advance or the issuance of a Letter of Credit shall
constitute a representation and warranty by the Borrower as of the date of the
making of such Advance or the issuance of such Letter of Credit that all the
conditions contained in this Section 3.2 have been satisfied.

                        Representations and Warranties
                        ------------------------------

     Section 4.1  Representations and Warranties. The Borrower hereby represents
                  ------------------------------
and warrants to each Lender as follows:

     (a)  Organization; Power; Qualification. As of the Agreement Date, the
          ----------------------------------                                
respective jurisdiction of organization and percentage ownership by the Borrower
or another Subsidiary of the Subsidiaries listed on Schedule 4 are true and
                                                    ----------             
correct. Each of the Borrower and its Subsidiaries is duly organized, validly
existing and in good standing under the laws of its state of organization. Each
of the Borrower and its Subsidiaries has the legal power and authority to own
its properties and to carry on its business as now being and hereafter proposed
to be conducted. Each of the Borrower and its Subsidiaries is duly qualified, in
good standing and authorized to do business in each jurisdiction in which the
character of its properties or the nature of its business requires such
qualification or authorization except where the failure to be so qualified or
authorized would not have a Material Adverse Effect.

     (b)  Authorization. The Borrower has corporate power and has taken all
          -------------                                                     
necessary corporate action to authorize it to borrow hereunder. Each of the
Borrower and its Subsidiaries has legal power and has taken all necessary legal
action to execute, deliver and perform the Loan Documents to which it is a party
in accordance with the terms thereof, and to consummate the transactions
contemplated thereby. Each Loan Document has been duly executed and delivered by
the Borrower or the Subsidiary executing it. Each of the Loan Documents to which
the Borrower and its Subsidiary are party is a legal, valid and binding
respective obligation of the Borrower or the Subsidiary, as applicable,
enforceable in accordance with its terms, subject, to enforcement of remedies,
to the following qualifications: (i) equitable principles generally, and (ii)
Debtor Relief Laws (insofar as any such law relates to the bankruptcy,
insolvency or similar event of the Borrower or any Subsidiary).

     (c)  Compliance with Other Loan Documents and Contemplated Transactions.
          ------------------------------------------------------------------  
The execution, delivery and performance by the Borrower and its Subsidiaries of
the Loan Documents to which they are respectively a party, and the consummation
of the transactions contemplated thereby, do not and will not (i) require any
consent or approval not already obtained, (ii) violate any Applicable Law, (iii)
conflict with, result in a breach of, or constitute a default under the articles
of incorporation, partnership agreement, trust agreement or by-laws, as
appropriate, of the Borrower or any Subsidiary, or under any Necessary
Authorization, indenture, agreement or other instrument, to which the Borrower
or any Subsidiary is a party or by which they or their respective properties may
be bound, or (iv) result in or require the creation or imposition of any Lien
upon or with respect to any property now owned or hereafter acquired by the
Borrower or any Subsidiary, except Permitted Liens.

                                      -43-
<PAGE>
 
     (d)  Business.  The Borrower and its Subsidiaries are engaged solely in the
          --------                                                              
business of manufacturing, mining, producing, transporting and selling
construction and construction related materials, including but not limited to
natural (sand and gravel) and manufactured aggregates, cement, concrete,
concrete products, clay and cement bricks, and concrete blocks; producing,
transporting and selling specialty products produced as by-products of such
construction and construction related materials; acquiring, developing and
selling real-estate; maintaining, owning, managing and operating aircraft;
acquiring, disposing, storing, treating, processing and recycling combustible
waste materials; producing and selling a broad range of carbon steel products
from recycled steel; recycling waste products; and acquiring, owning, disposing,
conducting and operating trades, services and businesses related and/or similar
to any of the foregoing; provided, however, Subsidiaries of the Borrower may
engage in Securitizations permitted by Section 7.4(a)(ii) hereof and activities
related to such Securitizations, provided that any such Subsidiary that engages
in such Securitizations shall engage in no other business.

     (e)  Licenses, etc.  All Necessary Authorizations, which if not obtained
          --------------                                                     
could be reasonably expected to have a Material Adverse Effect, have been duly
obtained, and are in full force and effect without any known conflict with the
rights of others and free from any unduly burdensome restrictions.  The Borrower
and its Subsidiaries are and will continue to be in compliance in all material
respects with all provisions thereof.  No circumstance exists which might impair
the utility of the Necessary Authorization or the right to renew such Necessary
Authorization the effect of which would have a Material Adverse Effect.  No
Necessary Authorization, which if suspended, canceled or revoked could
reasonably be expected to have a Material Adverse Effect, is the subject of any
pending or, to the best of the Borrower's knowledge, threatened challenge,
suspension, cancellation or revocation.

     (f)  Compliance with Law.  The Borrower and its Subsidiaries are in
          -------------------                                           
compliance in all respects with all Applicable Laws, except where the failure to
so comply would not have a Material Adverse Effect.  The Borrower and its
Subsidiaries have duly and timely filed all reports, statements and filings that
are required to be filed by any of them with any Governmental Authority, and are
in all material respects in compliance therewith, including without limitation
the rules and regulations of any Governmental Authority relating to the
operation of the Borrower's and each Subsidiary's business.  The Borrower and
its Subsidiaries have obtained all appropriate approvals and consents of, and
has made all filings with, the Governmental Authorities in connection with the
operation of the Borrower's and each Subsidiary's business.

     (g)  Title to Properties.  The Borrower and its Subsidiaries have good and
          -------------------                                                  
indefeasible title to, or a valid leasehold interest in, all of their material
assets.  None of their assets are subject to any Liens, except Permitted Liens.
No financing statement or other Lien filing (except relating to Permitted Liens)
is on file in any state or jurisdiction that names the Borrower or any of its
Subsidiaries as debtor or covers (or purports to cover) any assets of the
Borrower or any of its Subsidiaries.  The Borrower and its Subsidiaries have not
signed any such financing statement or filing, nor any security agreement
authorizing any Person to file any such financing statement or filing.

                                      -44-
<PAGE>
 
     (h)  Litigation.  Except as reflected on Schedule 3 hereto, there is no
          ----------                          ----------                    
action, suit or proceeding pending against, or, to the best of the Borrower's
knowledge, threatened against the Borrower, or in any other manner relating
directly and adversely to the Borrower or any of its Subsidiaries, or any of
their properties, in any court or before any arbitrator of any kind or before or
by any governmental body in which the amount claimed (in excess of applicable
insurance) exceeds $1,000,000.

     (i)  Taxes.  All federal, state and other tax returns of the Borrower and
          -----                                                               
its Subsidiaries required by law to be filed have been duly filed and all
federal, state and other taxes, assessments and other governmental charges or
levies upon the Borrower, its Subsidiaries or any of their respective
properties, income, profits and assets, which are due and payable, have been
paid, unless the same are being diligently contested in good faith by
appropriate proceedings, with adequate reserves established therefor, and no
Lien (other than a Permitted Lien) has attached and no foreclosure, distraint,
sale or similar proceedings have been commenced.  The charges, accruals and
reserves on the books of the Borrower and its Subsidiaries in respect of their
respective taxes are, in the judgment of the Borrower, adequate.

     (j)  Financial Statements; Material Liabilities.  The Borrower has 
          ---  ------------------------------------------               
furnished or caused to be furnished to the Lenders copies of its fiscal years
1997 and 1998 financial statements, which are prepared in good faith and
complete in all material respects and present fairly in accordance with GAAP the
financial position of the Borrower and its Subsidiaries as at such dates and the
results of operations for the periods then ended. The Borrower and its
Subsidiaries taken as a whole have no material liabilities, contingent or
otherwise, nor material losses, except as set forth in the May 31, 1998
financial statements.

     (k)  No Adverse Change.  Since May 31, 1998, no event or circumstances has
          -----------------                                                    
occurred or arisen that could have a Material Adverse Effect.

     (l)  ERISA.  None of the Borrower or its Controlled Group maintains or
          -----                                                            
contributes to any Plan other than those disclosed to the Administrative Lender
in writing.  Each such Plan (other than any Multiemployer Plan) is in compliance
in all material respects with the applicable provisions of ERISA, the Code, and
any other applicable Federal or state law, rule or regulation.  With respect to
each Plan (other than any Multiemployer Plan) of the Borrower and each member of
its Controlled Group, all reports required under ERISA or any other Applicable
Law to be filed with any governmental authority, the failure of which to file
could reasonably result in liability of the Borrower or any member of its
Controlled Group in excess of $100,000, have been duly filed.  All such reports
are true and correct in all material respects as of the date given.  No Plan of
the Borrower or any member of its Controlled Group has been terminated under
Section 4041(c) of ERISA nor has any accumulated funding deficiency (as defined
in Section 412(a) of the Code) been incurred (without regard to any waiver
granted under Section 412 of the Code), nor has any funding waiver from the
Internal Revenue Service been received or requested the result of which could
reasonably be expected to have a Material Adverse Effect. None of the Borrower
or any member

                                      -45-
<PAGE>
 
of its Controlled Group has failed to make any contribution or pay any amount
due or owing as required under the terms of any such Plan, or by Section 412 of
the Code or Section 302 of ERISA by the due date under Section 412 of the Code
and Section 302 of ERISA the result of which could reasonably be expected to
have a Material Adverse Effect. There has been no ERISA Event or any event
requiring disclosure under Section 4041(c)(3)(C) or 4063(a) of ERISA with
respect to any Plan or its related trust of the Borrower or any member of its
Controlled Group since the effective date of ERISA. The present value of the
benefit liabilities, as defined in Title IV of ERISA, of each Plan subject to
Title IV of ERISA (other than a Multiemployer Plan) of the Borrower and each
member of its Controlled Group does not exceed by more than $100,000 the present
value of the assets of each such Plan as of the most recent valuation date using
each such Plan's actuarial assumptions at such date. There are no pending, or to
the best of the Borrower's knowledge threatened, claims, lawsuits or actions
(other than routine claims for benefits in the ordinary course) asserted or
instituted against, and neither the Borrower nor any member of its Controlled
Group has knowledge of any threatened litigation or claims against, the assets
of any Plan or its related trust or against any fiduciary of a Plan with respect
to the operation of such Plan the result of which could reasonably be expected
to have a Material Adverse Effect. None of the Borrower or, to the best of the
Borrower's knowledge, any member of its Controlled Group has engaged in any
prohibited transactions, within the meaning of Section 406 of ERISA or Section
4975 of the Code, in connection with any Plan the result of which could
reasonably be expected to have a Material Adverse Effect. None of the Borrower
or any member of its Controlled Group has withdrawn from any Multiemployer Plan
except as described in writing to the Administrative Lender prior to the
Agreement Date, nor has incurred or reasonably expects to incur (A) any
liability under Title IV of ERISA (other than premiums due under Section 4007 of
ERISA to the PBGC), (B) any withdrawal liability (and no event has occurred
which with the giving of notice under Section 4219 of ERISA would result in such
liability) under Section 4201 of ERISA as a result of a complete or partial
withdrawal (within the meaning of Section 4203 or 4205 of ERISA) from a
Multiemployer Plan, or (C) any liability under Section 4062 of ERISA to the PBGC
or to a trustee appointed under Section 4042 of ERISA. None of the Borrower, any
member of its Controlled Group, or any organization to which the Borrower or any
member of its Controlled Group is a successor or parent corporation within the
meaning of ERISA Section 4069(b), has engaged in a transaction within the
meaning of ERISA Section 4069 the result of which could reasonably be expected
to have a Material Adverse Effect. None of the Borrower or any member of its
Controlled Group maintains or has established any Plan, which is a material
welfare benefit plan within the meaning of Section 3(1) of ERISA and which
provides for continuing benefits or coverage for any participant or any
beneficiary of any participant after such participant's termination of
employment, except as may be required by the Consolidated Omnibus Budget
Reconciliation Act of 1985, as amended ("COBRA") and the regulations thereunder.
Each of Borrower and its Controlled Group which maintains a Plan which is a
welfare benefit plan within the meaning of Section 3(1) of ERISA has complied in
all material respects with any applicable notice and continuation requirements
of COBRA and the regulations thereunder. None of the Borrower or any member of
its Controlled Group maintains, has established, or has ever participated in a
multiemployer welfare benefit arrangement within the meaning of Section 3(40)(A)
of ERISA.

<PAGE>
 
     (m)  Compliance with Regulations T, U and X.  The Borrower is not engaged
          --------------------------------------                              
principally or as one of its important activities in the business of extending
credit for the purpose of purchasing or carrying any margin stock within the
meaning of Regulations T, U and X of the Board of Governors of the Federal
Reserve System.  No more than 25% of the assets of the Borrower and its
Subsidiaries consist of margin stock.  None of the Borrower and its Subsidiaries
nor any agent acting on their behalf, have taken or will knowingly take any
action which might cause this Agreement or any other Loan Documents to violate
any regulation of the Board of Governors of the Federal Reserve System or to
violate the Securities Exchange Act of 1934, in each case as in effect now or as
the same may hereafter be in effect.  Neither the making of the Advances nor the
use of the proceeds thereof will violate, or be inconsistent with, the
provisions of Regulations T, U or X of said Board of Governors.

     (n)  Governmental Regulation.  The Borrower and its Subsidiaries are not
          -----------------------                                            
required to obtain any Necessary Authorization that has not already been
obtained from, or effect any material filing or registration that has not
already been effected with,  any Governmental Authority in connection with the
execution and delivery of this Agreement or any other Loan Document, or the
performance thereof (other than any enforcement of remedies by the
Administrative Lender on behalf of the Lenders) in accordance with their
respective terms, including any borrowings hereunder.

     (o)  Absence of Default.  The Borrower and its Subsidiaries are in
          ------------------                                           
compliance in all material respects with all of the provisions of their articles
of incorporation and by-laws, and no event has occurred or failed to occur,
which has not been remedied or waived, the occurrence or non-occurrence of which
constitutes, or which with the passage of time or giving of notice or both would
constitute, (i) a Default or an Event of Default or (ii) a default by the
Borrower or any of its Subsidiaries under any indenture, agreement or other
instrument, or any judgment, decree or order to which the Borrower or any of its
Subsidiaries or by which they or any of their material properties is bound.

     (p)  Investment Company Act.  The Borrower is not required to register 
          ----------------------                                            
under the provisions of the Investment Company Act of 1940, as amended. Neither
the entering into or performance by the Borrower of this Agreement nor the
issuance of the Notes violates any provision of such act or requires any
consent, approval, or authorization of, or registration with, the Securities and
Exchange Commission or any other governmental or public body of authority
pursuant to any provisions of such act.

     (q)  Environmental Matters.  Each of the Borrower and its Subsidiaries is
          ---------------------                                               
in compliance with all Applicable Environmental Laws in effect in each
jurisdiction where it is presently doing business or has done business, and in
which the failure so to comply could have a Material Adverse Effect. Neither the
Borrower nor any of the Subsidiaries is subject to any liability under any
Applicable Environmental Laws that, in the aggregate, could have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary has received any (a)
notice from any Governmental Authority by which any of its present or 
previously-owned or leased real properties has been

                                      -47-
<PAGE>
 
designated, listed, or identified in any manner by any Governmental Authority
charged with administering or enforcing any Applicable Environmental Law as a
Hazardous Substance disposal or removal site, "Super Fund" clean-up site, or
candidate for removal or closure pursuant to any Applicable Environmental Law,
(b) notice of any Lien arising under or in connection with any Applicable
Environmental Law that has attached to any revenues of, or to, any of its owned
or leased real properties, or (c) summons, citation, notice, directive, letter,
or other communication, written or oral, from any Governmental Authority
concerning any intentional or unintentional action or omission by the Borrower
or such Subsidiary in connection with its ownership or leasing of any real
property resulting in the releasing, spilling, leaking, pumping, pouring,
emitting, emptying, dumping, or otherwise disposing of any Hazardous Substance
into the environment resulting in any material violation of an Applicable
Environmental Law, in each case in (a), (b) and (c) immediately preceding where
the effect of which could have a Material Adverse Effect.

     (r)  Certain Fees.  No broker's, finder's or other fee or commission will
          ------------                                                        
be payable by the Borrower (other than to the Lenders hereunder) with respect to
the making of the Commitment or the Advances hereunder or the issuance of any
Letters of Credit.  The Borrower agrees to indemnify and hold harmless the
Administrative Lender and each Lender from and against any claims, demand,
liability, proceedings, costs or expenses asserted with respect to or arising in
connection with any such fees or commissions.

     (s)  Necessary Authorizations.  No event has occurred which permits (or 
          ------------------------                                           
with the passage of time would permit) the revocation or termination of any
Necessary Authorization, or which could result in the imposition of any
restriction thereon of such a nature that could reasonably be expected to have a
Material Adverse Effect.

     (t)  Patents, Etc.  The Borrower and its Subsidiaries have obtained all
          ------------                                                      
patents, trademarks, service-marks, trade names, copyrights, licenses and other
rights, free from burdensome restrictions, that are necessary for the operation
of their business as presently conducted and as proposed to be conducted.
Nothing has come to the attention of the Borrower or any of its Subsidiaries to
the effect that (i) any process, method, part or other material presently
contemplated to be employed by the Borrower or any Subsidiary may infringe any
patent, trademark, service-mark, trade name, copyright, license or other right
owned by any other Person, or (ii) there is pending or overtly threatened any
claim or litigation against or affecting the Borrower or any Subsidiary
contesting its right to sell or use any such process, method, part or other
material.

     (u)  Disclosure.  Neither this Agreement nor any other document, 
          ----------                                                  
certificate or statement which has been furnished to any Lender by or on behalf
of the Borrower or any Subsidiary in connection herewith contained any untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statement contained herein and therein not misleading at the
time it was furnished. There is no fact known to the Borrower and not known to
the public generally that could reasonably be expected to materially adversely
affect the assets or business of the Borrower and its Subsidiaries, or in the
future could reasonably be expected (so far as the Borrower can now foresee) to
have a Material Adverse Effect, which has not been set forth in this Agreement
or in the 

                                      -48-
<PAGE>
 
documents, certificates and statements furnished to the Lenders by or on behalf
of the Borrower prior to the date hereof in connection with the transaction
contemplated hereby.

     (v)  Solvency.  The Borrower is, and Borrower and its Subsidiaries on a
          --------                                                          
consolidated basis are, Solvent.

     (w)  Common Enterprise.  The Borrower and its Subsidiaries are engaged in
          -----------------                                                   
the businesses set forth in Section 4.1(d) hereof.  These operations require
financing on a basis such that the credit supplied can be made available from
time to time to the Borrower and various of the Subsidiaries, as required for
the continued successful operation of the Borrower and its Subsidiaries as a
whole.  The Borrower and its Subsidiaries expect to derive benefit (and the
boards of directors of the Borrower and its Subsidiaries have determined that
the Borrower and the Subsidiaries may reasonably be expected to derive benefit),
directly or indirectly, from the credit extended by Lenders hereunder, both in
their separate capacities and as members of the group of companies, since the
successful operation and condition of the Borrower and its Subsidiaries is
dependent on the continued successful performance of the functions of the group
as a whole.

     (x)  Year 2000 Compliance.  The Borrower has (a) initiated a review and
          --------------------                                              
assessment of all areas within its and each of its Subsidiaries' business and
operations (including those affected by its suppliers and vendors) that could be
adversely affected by the "Year 2000 Problem" (that is, the risk that computer
applications used by the Borrower or any of its Subsidiaries (or its suppliers
and vendors) may be unable to recognize and perform properly date-sensitive
functions involving certain dates prior to and any date after December 31,
1999), (b) developed a plan and timeline for addressing the Year 2000 Problem on
a timely basis, and (c) to date, implemented that plan in accordance with that
timetable.  The Borrower reasonably believes that all computer applications
(including, based on representations from its suppliers and vendors, those of
its suppliers and vendors) that are material to its or any of its Subsidiaries'
business and operations will on a timely basis be able to perform properly date-
sensitive functions for all dates before and after January 1, 2000 (that is, be
"Year 2000 Compliant"), except to the extent that a failure to do so could not
 -------------------                                                          
reasonably be expected to have a Material Adverse Effect.

     Section 4.2  Survival of Representations and Warranties, etc.  All
                  -----------------------------------------------      
representations and warranties made under this Agreement and the other Loan
Documents shall be deemed to be made at and as of the Agreement Date and at and
as of the date of each Advance and each Letter of Credit, and each shall be true
and correct when made, except to the extent (a) previously fulfilled in
accordance with the terms hereof, (b) applicable to a specific date or otherwise
subsequently inapplicable, or (c) previously waived in writing by the

AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, CLAIMS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND OR
NATURE WHATSOEVER (INCLUDING, WITHOUT LIMITATION, THE FEES AND DISBURSEMENTS OF
COUNSEL FOR SUCH INDEMNITEES IN CONNECTION WITH ANY INVESTIGATIVE,
ADMINISTRATIVE OR JUDICIAL PROCEEDING, WHETHER OR NOT SUCH INDEMNITEES SHALL BE

FEDERAL, STATE, OR LOCAL LAWS AND REGULATIONS, UNDER COMMON LAW OR AT EQUITABLE
CAUSE, OR ON CONTRACT, TORT OR OTHERWISE, ARISING FROM OR CONNECTED WITH THE
PAST, PRESENT OR FUTURE OPERATIONS OF THE BORROWER OR ITS PREDECESSORS IN
INTEREST, OR THE PAST, PRESENT OR FUTURE ENVIRONMENTAL CONDITION OF PROPERTY OF
THE BORROWER OR ANY SUBSIDIARY OR THE VIOLATION OR ASSERTED VIOLATION BY THE
BORROWER OR ANY SUBSIDIARY OF ANY APPLICABLE LAW, INCLUDING ANY APPLICABLE
ENVIRONMENTAL LAW), IN ANY MANNER RELATING TO OR ARISING OUT OF THIS AGREEMENT,

TRANSACTION RELATING OR ATTENDANT THERETO, THE MAKING OF ANY PARTICIPATIONS IN
THE ADVANCES AND THE MANAGEMENT OF THE ADVANCES, INCLUDING IN CONNECTION WITH,
OR AS A RESULT, IN WHOLE OR IN PART, OF ANY NEGLIGENCE OF ADMINISTRATIVE LENDER
OR ANY LENDER (OTHER THAN THOSE MATTERS RAISED EXCLUSIVELY BY A PARTICIPANT
AGAINST THE ADMINISTRATIVE LENDER OR ANY LENDER AND NOT THE BORROWER), OR THE
USE OR INTENDED USE OF THE PROCEEDS OF THE ADVANCES HEREUNDER, OR IN CONNECTION
WITH ANY INVESTIGATION OF ANY POTENTIAL MATTER COVERED HEREBY, BUT EXCLUDING (I)
ANY CLAIM OR LIABILITY FROM AN INDEMNITEE THAT ARISES AS THE RESULT OF THE GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY SUCH INDEMNITEE, AS FINALLY JUDICIALLY
DETERMINED BY A COURT OF COMPETENT JURISDICTION, AND (II) MATTERS RAISED BY ONE
LENDER AGAINST ANOTHER LENDER OR BY ANY SHAREHOLDERS OF A LENDER AGAINST A
LENDER OR ITS MANAGEMENT (COLLECTIVELY, "INDEMNIFIED MATTERS"). TO THE EXTENT
                                         -------------------

REPRESENTATION.

     (b)  In addition, the Borrower shall periodically, upon request, reimburse
each Indemnitee for its reasonable legal and other actual expenses (including
the cost of any investigation and preparation) incurred in connection with any

unavailable to any Indemnitee or insufficient to hold any Indemnitee harmless

                                      -52-
<PAGE>
 
with respect to Indemnified Matters, then the Borrower shall contribute to the
amount paid or payable by such Indemnitee as a result of such loss, claim,
damage or liability in such proportion as is appropriate to reflect not only the
relative benefits received by the Borrower and the Borrower's stockholders on
the one hand and such Indemnitee on the other hand but also the relative fault
of the Borrower and such Indemnitee, as well as any other relevant equitable
considerations.  The reimbursement, indemnity and contribution obligations under
this Section shall be in addition to any liability which the Borrower may
otherwise have, shall extend upon the same terms and conditions to each
Indemnitee, and shall be binding upon and inure to the benefit of any
successors, assigns, heirs and personal representatives of the Borrower, the
Administrative Lender, the Lenders and all other Indemnitees.  This Section 5.10
shall survive any termination of this Agreement and payment of the Obligations.

Administrative Lender in the event the Borrower discovers or determines that any
computer application (including those of its suppliers and vendors) that is
material to its or any of its Subsidiaries' business and operations will not be
Year 2000 Compliant, except to the extent that such failure could not reasonably
be expected to have a Material Adverse Effect.

                           Changes in Circumstances
                           ------------------------

     Section 9.1  LIBOR Basis Determination Inadequate.  If with respect to any
                  ------------------------------------                         
proposed LIBOR Advance for any Interest Period, any Lender determines that (i)
deposits in dollars (in the applicable amount) are not being offered to that
Lender in the relevant market for such Interest Period or (ii) the LIBOR Basis
for such proposed LIBOR Advance does not adequately cover the cost to such
Lender of making and maintaining such proposed LIBOR Advance for such Interest
Period, such Lender shall forthwith give notice thereof to the Borrower,
whereupon until such Lender notifies the Borrower that the circumstances giving
rise to such situation no longer exist, the obligation of such Lender to make
LIBOR Advances shall be suspended.

     Section 9.2  Illegality.  If any applicable law, rule or regulation, or any
                  ----------                                                    
change therein or adoption thereof, or interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Lender (or
its LIBOR Lending Office) with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency,
shall make it unlawful or impossible for such Lender (or its LIBOR Lending
Office) to make, maintain or fund its LIBOR Advances or Bid Rate Advances, such
Lender shall so notify the Borrower and the Administrative Lender.  Before
giving any notice to the Borrower pursuant to this Section, the notifying Lender
shall designate a different LIBOR Lending Office or other lending office if such
designation will avoid the need for giving such notice and will not, in the sole
judgment of the Lender, be materially disadvantageous to the Lender.  Upon
receipt of such notice, notwithstanding anything contained in Article 2 hereof,
the Borrower shall repay in full the then outstanding principal amount of each
LIBOR Advance or Bid Rate Advance owing to the notifying Lender, together with
accrued interest thereon, on either (a) the last day of the Interest Period
applicable to such Advance, if the Lender may lawfully continue to maintain and
fund such Advance to such day, or (b) immediately, if the Lender may not
lawfully continue to fund and maintain such Advance to such day.  Concurrently
with repaying each affected LIBOR Advance owing to such Lender, notwithstanding
anything contained in Article 2 hereof, the Borrower shall borrow a Base Rate
Advance from such Lender,

                                      -67-
<PAGE>
 
and such Lender shall make such Base Rate Advance, in an amount such that the 
outstanding principal amount of the Advances owing to such Lender shall equal 
the outstanding principal amount of the Advances owing immediately prior to 
such repayment, and such Base Rate Advance shall be payable on the same date
or dates as the affected LIBOR Advances of such Lender would have otherwise
been due and payable but for this Section 9.2.

     Section 9.3  Increased Costs.
                  --------------- 

     (a)  If any applicable law, rule or regulation, or any change in or
adoption of any law, rule or regulation, or any interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof or compliance by any Lender
(or its LIBOR Lending Office) with any request or directive (whether or not
having the force of law) of any such authority, central bank or compatible
agency:

          (i)  shall subject a Lender (or its LIBOR Lending Office) to any Tax
     (net of any tax benefit engendered thereby) with respect to its LIBOR
     Advances, Bid Rate Advances or its obligation to make such Advances, or
     shall change the basis of taxation of payments to a Lender (or to its LIBOR
     Lending Office) of the principal of or interest on its LIBOR Advances, Bid
     Rate Advances or in respect of any other amounts due under this Agreement,
     as the case may be, or its obligation to make such Advances (except for
     changes in the rate of tax on the overall net income, net worth or capital
     of the Lender and franchise taxes, doing business taxes or minimum taxes
     imposed upon such Lender); or

          (ii) shall impose, modify or deem applicable any reserve (including,
     without limitation, any imposed by the Board of Governors of the Federal
     Reserve System), special deposit or similar requirement against assets of,
     deposits with or for the account of, or credit extended by, a Lender's
     LIBOR Lending Office or shall impose on the Lender (or its LIBOR Lending
     Office) or on the United States market for certificates of deposit or the
     London interbank market any other condition affecting its LIBOR Advances or
     Bid Rate Advances or its obligation to make such Advances;

and the result of any of the foregoing is to increase the cost to a Lender (or
its LIBOR Lending Office) of making or maintaining any LIBOR Advances or Bid
Rate Advances, or to reduce the amount of any sum received or receivable by a
Lender (or its LIBOR Lending Office) with respect thereto, by an amount deemed
by a Lender to be material, then, within 15 days after demand by a Lender, the
Borrower agrees to pay to such Lender such additional amount as will compensate
such Lender for such increased costs or reduced amounts, subject to Section 11.9
hereof.  The affected Lender will as soon as practicable notify the Borrower of
any event of which it has knowledge, occurring after the date hereof, which will
entitle such Lender to compensation pursuant to this Section and will designate
a different LIBOR Lending Office or other lending office if such designation
will avoid the need for, or reduce the amount of, such compensation and will
not, in the sole judgment of the affected Lender made in good faith, be
disadvantageous to such Lender.

                                      -68-
<PAGE>
 
     (b)  A certificate of any Lender claiming compensation under this Section
and setting forth the additional amounts to be paid to it hereunder and
calculations therefor shall be conclusive in the absence of manifest error.  In
determining such amount, a Lender may use any reasonable averaging and
attribution methods.  If a Lender demands compensation under this Section, the
Borrower may at any time, upon at least five Business Days' prior notice to the
Lender, after reimbursement to the Lender by the Borrower in accordance with
this Section of all costs incurred, prepay in full the then outstanding LIBOR
Advances or Bid Rate Advances of the Lender, together with accrued interest
thereon to the date of prepayment, along with any reimbursement required under
Section 2.9 hereof.  Concurrently with prepaying such LIBOR Advances, the
Borrower shall borrow a Base Rate Advance from the Lender, and the Lender shall
make such Base Rate Advance, in an amount such that the outstanding principal
amount of the Advances owing to such Lender shall equal the outstanding
principal amount of the Advances owing immediately prior to such prepayment, and
such Base Rate Advance shall be payable on the same date or dates as the LIBOR
Advances of such Lender would have otherwise been due and payable but for this
Section 9.3.

     Section 9.4    Base Rate Advances Rather than LIBOR Advances. If notice has
                    ---------------------------------------------    
been given pursuant to Section 9.1, 9.2 or 9.3 hereof suspending the obligation
of a Lender to make LIBOR Advances, or requiring LIBOR Advances of a Lender to
be repaid or prepaid, then, unless and until the Lender notifies the Borrower
that the circumstances giving rise to such repayment no longer apply, all
Advances which would otherwise be made by such Lender as LIBOR Advances shall be
made instead as Base Rate Advances, which shall be payable on the same date or
dates as the LIBOR Advances made by the other Lenders.

     Section 9.5    Capital Adequacy.  If either (a) the introduction of or any
                    ----------------                                           
change in or in the interpretation of any law, rule or regulation or (b)
compliance by a Lender with any law, rule or regulation or any guideline or
request from any central bank or other governmental authority (whether or not
having the force of law) affects or would affect the amount of capital required
or expected to be maintained by a Lender or any corporation controlling such
Lender, and such Lender determines that the amount of such capital is increased
by or based upon the existence of such Lender's Commitment or Advances hereunder
and other commitments or advances of such Lender of this type, then, upon demand
by such Lender, subject to Section 11.9, the Borrower shall immediately pay to
such Lender, from time to time as specified by such Lender, additional amounts
sufficient to compensate such Lender with respect to such circumstances, to the
extent that such Lender reasonably determines in good faith such increase in
capital to be allocable to the existence of such Lender's Commitment hereunder.
A certificate as to such amounts submitted to the Borrower by a Lender
hereunder, shall, in the absence of manifest error, be conclusive and binding
for all purposes.

                            Agreement Among Lenders
                            -----------------------

     Section 10.1   Agreement Among Lenders.  The Lenders agree among themselves
                    -----------------------                                     
that:

     (a)  Administrative Lender.  Each Lender hereby appoints the Administrative
          ---------------------                                                 
Lender as its nominee in its name and on its behalf, to receive all documents
and items to be furnished hereunder; to act as nominee for and on behalf of all
Lenders under the Loan Documents; to, except as otherwise expressly set forth
herein, take such action as may be requested by the Determining Lenders,
provided that, unless and until the Administrative Lender shall have received
such requests, the Administrative Lender may take such administrative action, or
refrain from taking such administrative action, as it may deem advisable and in
the best interests of the Lenders; to arrange the means whereby the proceeds of
the Advances of the Lenders are to be made available to the Borrower; to
distribute promptly to each Lender information, requests and documents received
from the Borrower, and each payment (in like funds received) with respect to any
of such Lender's Advances, fee or other amount; and to deliver to the Borrower
requests, demands, approvals and consents received from the Lenders.
Administrative Lender agrees to promptly distribute to each Lender, at such
Lender's address set forth below information, requests, documents and payments
received from the Borrower.  The Administrative Lender shall have no trustee or
other fiduciary relationship in respect of any Lender by reason of this
Agreement or any other Loan Document.  The duties of the Administrative Lender
are mechanical and administrative in nature.

     (b)  Replacement of Administrative Lender. Should the Administrative Lender
          ------------------------------------       
or any successor Administrative Lender ever cease to be a Lender hereunder, or
should the Administrative Lender or any successor Administrative Lender ever
resign as Administrative Lender, or should the Administrative Lender or any
successor Administrative Lender ever be removed with cause by the Determining
Lenders, then the Lender appointed by the other Lenders shall forthwith become
the Administrative Lender, and the Borrower and the Lenders shall execute such
documents as any Lender may reasonably request to reflect such change.  Any
resignation or removal of the Administrative Lender or any successor
Administrative Lender shall become effective upon the appointment by the Lenders
of a successor Administrative Lender; provided, however, that if the Lenders
fail for any reason to appoint a successor within 60 days after such removal or
resignation, the Administrative Lender or any successor Administrative Lender
(as the case may be) shall thereafter have no obligation to act as
Administrative Lender hereunder.  Notwithstanding any Administrative Lender's
resignation or removal hereunder, the provisions of this Article shall continue
to inure to its benefit as to any actions taken or omitted to be taken by it
while it was the Administrative Lender hereunder.

     (c)  Expenses.  Each Lender shall pay its pro rata share, based on its
          --------                                                         
Specified Percentage, of any expenses paid by the Administrative Lender directly
and solely in connection with any of the Loan Documents if Administrative Lender
does not receive reimbursement therefor from other sources within 60 days after
the date incurred, unless payment of such fees is being diligently 

                                      -70-
<PAGE>
 
disputed by such Lender or the Borrower in good faith. Any amount so paid by the
Lenders to the Administrative Lender shall be returned by the Administrative
Lender pro rata to each paying Lender to the extent later paid by the Borrower
or any other Person on the Borrower's behalf to the Administrative Lender.

     (d)  Delegation of Duties. The Administrative Lender may execute any of its
          --------------------       
duties hereunder by or through officers, directors, employees, attorneys or
agents, and shall be entitled to (and shall be protected in relying upon) advice
of counsel concerning all matters pertaining to its duties hereunder.

     (e)  Reliance by Administrative Lender.  The Administrative Lender and its
          ---------------------------------                                    
officers, directors, employees, attorneys and agents shall be entitled to rely
and shall be fully protected in relying on any writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telex or teletype
message, statement, order, or other document or conversation reasonably believed
by it or them in good faith to be genuine and correct and to have been signed or
made by the proper Person and, with respect to legal matters, upon opinions of
counsel selected the Administrative Lender.  The Administrative Lender may, in
its reasonable judgment, deem and treat the payee of any Note as the owner
thereof for all purposes hereof.

     (f)  Limitation of Administrative Lender's Liability.  Neither the
          -----------------------------------------------              
Administrative Lender nor any of its officers, directors, employees, attorneys
or agents shall be liable for any action taken or omitted to be taken by it or
them hereunder in good faith and believed by it or them to be within the
discretion or power conferred to it or them by the Loan Documents or be
responsible for the consequences of any error of judgment, except for its or
their own gross negligence or wilful misconduct.  Except as aforesaid, the
Administrative Lender shall be under no duty to enforce any rights with respect
to any of the Advances, or any security therefor.  The Administrative Lender
shall not be compelled to do any act hereunder or to take any action towards the
execution or enforcement of the powers hereby created or to prosecute or defend
any suit in respect hereof, unless indemnified to its satisfaction against loss,
cost, liability and expense.  The Administrative Lender shall not be responsible
in any manner to any Lender for the effectiveness, enforceability, genuineness,
validity or due execution of any of the Loan Documents, or for any
representation, warranty, document, certificate, report or statement made herein
or furnished in connection with any Loan Documents, or be under any obligation
to any Lender to ascertain or to inquire as to the performance or observation of
any of the terms, covenants or conditions of any Loan Documents on the part of
the Borrower.  TO THE EXTENT NOT REIMBURSED BY THE BORROWER, EACH LENDER HEREBY
JOINTLY AND SEVERALLY INDEMNIFIES AND HOLDS HARMLESS THE ADMINISTRATIVE LENDER,
PRO RATA ACCORDING TO ITS SPECIFIED PERCENTAGE, FROM AND AGAINST ANY AND ALL
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS,
COSTS, EXPENSES AND/OR DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY
BE IMPOSED ON, ASSERTED AGAINST, OR INCURRED BY THE ADMINISTRATIVE LENDER (IN
ITS CAPACITY AS ADMINISTRATIVE LENDER AND NOT AS A LENDER) IN ANY WAY WITH
RESPECT TO ANY LOAN DOCUMENTS OR ANY 

                                      -71-
<PAGE>
 
ACTION TAKEN OR OMITTED BY THE ADMINISTRATIVE LENDER IN ITS CAPACITY AS
ADMINISTRATIVE LENDER AND NOT AS A LENDER UNDER THE LOAN DOCUMENTS (INCLUDING
ANY NEGLIGENT ACTION OF THE ADMINISTRATIVE LENDER), EXCEPT TO THE EXTENT THE
SAME RESULT FROM GROSS NEGLIGENCE OR WILFUL MISCONDUCT BY THE ADMINISTRATIVE
LENDER.

     (g)  Liability Among Lenders.  No Lender shall incur any liability (other
          -----------------------                                             
than the sharing of expenses and other matters specifically set forth herein and
in the other Loan Documents) to any other Lender, except for acts or omissions
in bad faith.

     (h)  Rights as Lender.  With respect to its commitment hereunder, the
          ----------------                                                
Advances made by it and Note issued to it, the Administrative Lender shall have
the same rights as a Lender and may exercise the same as though it were not the
Administrative Lender, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include the Administrative Lender in its individual
capacity.  The Administrative Lender or any Lender may accept deposits from, act
as trustee under indentures of, and generally engage in any kind of business
with, the Borrower and any of its Affiliates, and any Person who may do business
with or own securities of the Borrower or any of its Affiliates, all as if the
Administrative Lender were not the Administrative Lender hereunder and without
any duty to account therefor to the Lenders.

     Section 10.2   Lender Credit Decision. Each Lender acknowledges that it
                    ----------------------      
has, independently and without reliance upon the Administrative Lender or any
other Lender and based upon the financial statements referred to in Sections
4.1(j), 6.1 and 6.2 hereof, and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and without
reliance upon the Administrative Lender or any other Lender and based upon such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement and the other Loan Documents.

     Section 10.3   Benefits of Article.  None of the provisions of this Article
                    -------------------                                         
shall inure to the benefit of any Person other than Lenders; consequently, no
Person shall be entitled to rely upon, or to raise as a defense, in any manner
whatsoever, the failure of the Administrative Lender or any Lender to comply
with such provisions.

     Section 11.2   Expenses.  The Borrower shall promptly pay:
                    --------                                   
     (a)  all reasonable out-of-pocket expenses of the Administrative Lender in
connection with the preparation, negotiation, execution and delivery of this
Agreement and the other Loan Documents, the transactions contemplated hereunder
and thereunder, and the making of Advances and the issuance of Letters of Credit
hereunder, including without limitation the reasonable fees and disbursements of
Special Counsel;

     (b)  all reasonable out-of-pocket expenses and attorneys' fees of the
Administrative Lender in connection with the administration of the transactions
contemplated in this Agreement and the other Loan Documents and the preparation,
negotiation, execution and delivery of any waiver, amendment or consent by the
Lenders relating to this Agreement or the other Loan Documents; and

     (c)  all costs, out-of-pocket expenses and attorneys' fees of the
Administrative Lender and each Lender (including reasonable allocated costs of
in-house counsel of any Lender) incurred for enforcement, collection,
restructuring, refinancing and "work-out", or otherwise incurred in obtaining
performance under the Loan Documents, and all costs and out-of-pocket expenses
of collection if default is made in the payment of the Notes, which in each case
shall include without limitation fees and expenses of consultants, counsel for
the Administrative Lender and any Lender, and administrative fees for the
Administrative Lender.

     Section 11.3   Waivers.  The rights and remedies of the Lenders under this
                    -------                                                    
Agreement and the other Loan Documents shall be cumulative and not exclusive of
any rights or remedies which they would otherwise have.  No failure or delay by
the Administrative Lender or any Lender in exercising any right shall operate as
a waiver of such right.  The Lenders expressly reserve the right to require
strict compliance with the terms of this Agreement in connection with any
funding of a request for an Advance and the Issuing Bank expressly reserves the
right to require strict compliance with the terms of this Agreement in
connection with any issuance of a Letter of Credit.  In the event that any
Lender decides to fund an Advance or the Issuing Bank decides to issue a Letter
of Credit at a time when the Borrower is not in strict compliance with the terms
of this Agreement, such decision by such Lender shall not be deemed to
constitute an undertaking by the Lender to fund any further requests for
Advances or by the Issuing Bank to issue any additional Letters of Credit or
preclude the Lenders from exercising any rights available under the Loan
Documents or at law or equity. Any waiver or indulgence granted by the Lenders
shall not constitute a modification of this Agreement, except to the extent
expressly provided in such waiver or indulgence, or constitute a course of
dealing by the Lenders at variance with the terms of the Agreement such as to
require further notice by the Lenders of the Lenders' intent to require strict
adherence to the terms of the Agreement in the future. Any such actions shall
not in any way affect the ability of the Administrative Lender or the Lenders,
in their discretion, to exercise any rights available to them under this
Agreement or under any other agreement, whether or not the Administrative Lender
or any of the Lenders are a party thereto, relating to the Borrower.

     Section 11.4   Determination by the Lenders Conclusive and Binding.  Any
                    ---------------------------------------------------      
material determination required or expressly permitted to be made by the
Administrative Lender or any Lender under this Agreement shall be made in its
reasonable judgment and in good faith, and shall when made, absent manifest

     Section 11.5   Set-Off.  In addition to any rights now or hereafter granted
                    -------                                                     
under Applicable Law and not by way of limitation of any such rights, upon the
occurrence of an Event of Default, each Lender and any subsequent holder of any
Note, and any assignee or participant in any Note is hereby authorized by the
Borrower at any time or from time to time, without notice to the Borrower or any
other Person, any such notice being hereby expressly waived, to set-off,

by certificates of deposit, in each case whether matured or unmatured) and any
other Indebtedness at any time held or owing by such Lender or holder to or for
the credit or the account of the Borrower, against and on account of the
Obligations and other liabilities of the Borrower to such Lender or holder,

demand hereunder, or (b) the Lender or holder shall have declared the principal
of and interest on the Advances and other amounts due hereunder to be due and
payable as permitted by Section 8.2 and although such obligations and

any Note shall be subject to pro rata treatment of all Obligations and other
liabilities hereunder.

     Section 11.6   Assignment.
                    ----------

     (a)  The Borrower may not assign or transfer any of its rights or
obligations hereunder or under the other Loan Documents without the prior
written consent of the Lenders.

     (b)  No Lender shall be entitled to assign its interest in this Agreement,
its Notes or its Advances, except as hereinafter set forth.

     (c)  A Lender may at any time sell participations in all or any part of its
Advances (collectively, "Participations") to any banks or other financial
                         --------------                                  
institutions ("Participants") provided that such Participation shall not confer
               ------------                                                    
on any Person (other than the parties hereto) any right to vote on, approve or
sign amendments or waivers, or any other independent benefit or any legal or
equitable right, remedy or other claim under this Agreement or any other Loan
Documents, other than the right to vote on, approve, or sign amendments or
waivers or consents with respect to items that would result in (i) any increase
in the commitment of any Participant; or (ii)(A) the extension of the date of
maturity of, or (B) the extension of the due date for any payment of principal,
interest or fees respecting, or (C) the reduction of the amount of any

                                      -75-
<PAGE>
 
the Participants shall be entitled to the benefits of Article 9 and Section 11.5
hereof as though they were Lenders and the Lenders may provide copies of all
financial information received from the Borrower to such Participants. To the
fullest extent it may effectively do so under Applicable Law, the Borrower
agrees that any Participant may exercise any and all rights of banker's lien,
set-off and counterclaim with respect to this Participation as fully as if such
Participant were the holder of the Advances in the amount of its Participation.
Any Lender selling a Participation hereunder shall give prompt notice thereof to
the Borrower and the Administrative Lender.

     (d)  Each Lender may assign to one or more Eligible Assignees its rights
and obligations under this Agreement and the other Loan Documents; provided,
                                                                   -------- 
however, that (i) each such assignment shall be of a constant, and not a
- -------                                                                 
varying, percentage of the Lender's rights and obligations under this Agreement
(excluding, however, any Bid Rate Advances), (ii) the amount of such assigning
Lender's portion of the Commitment, Advances and Reimbursement Obligations being
assigned pursuant to each such assignment (determined as of the date of the
assignment with respect to such assignment) shall in no event be less than the
lesser of (A) $10,000,000, or (B) the applicable Lender's portion of the
Commitment, (iii) the applicable Lender, Administrative Lender and applicable
Eligible Assignee shall execute and deliver to the Administrative Lender an
Assignment and Acceptance Agreement (an "Assignment Agreement") in substantially
                                         --------------------                   
the form of Exhibit E hereto, together with the Notes subject to such
            ---------                                                
assignment, (iv) the Eligible Assignee or the Lender executing the Assignment,
as the case may be, shall deliver to the Administrative Lender a processing fee
of $3,500, and (v) unless waived by the Borrower, the Administrative Lender
shall give the Borrower notice of any proposed assignment no later than 10 days
prior to any assignment by any Lender.  Upon such execution, delivery and
acceptance from and after the effective date specified in each Assignment, which
effective date shall be at least three Business Days after the execution
thereof, (A) the Eligible Assignee thereunder shall be party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment, have the rights and obligations of a Lender hereunder and
(B) the applicable Lender shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment, relinquish such
rights and be released from such obligations under this Agreement, except those
rights that expressly survive termination of this Agreement.

     (e)  Notwithstanding anything in clause (d) above to the contrary, any
Lender may assign and pledge all or any portion of its Advances and Notes to any
Federal Reserve Bank as collateral security pursuant to Regulation A of F.R.S.
Board and any Operating Circular issued by such Federal Reserve Bank; provided,
however, that no such assignment under this clause (e) shall release the
assignor Lender from its obligations hereunder.

     (f)  Upon its receipt of an Assignment Agreement executed by a Lender and
an Eligible Assignee, and any Note subject to such assignment, the Borrower
shall, within three Business Days after its receipt of such Assignment
Agreement, at its own expense, execute and deliver to the Administrative Lender
in exchange for the surrendered Note a new Note to the order of such Eligible
Assignee in an amount equal to the portion of the Advances, Reimbursement
Obligations and Commitment assigned to it pursuant to such Assignment Agreement
and a new Note to the order of 

                                      -76-
<PAGE>
 
the assigning Lender in an amount equal to the portion of the Advances and
Commitment retained by it hereunder. Such new Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Note, shall be dated the effective date of such Assignment Agreement and shall
otherwise be in substantially the form of Exhibit A hereto.
                                          ---------        

     (g)  Any Lender may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section 11.6, disclose to
the Eligible Assignee or Participant or proposed Eligible Assignee or
Participant, any information relating to the Borrower furnished to such Lender
by or on behalf of the Borrower.

     (h)  Except as specifically set forth in this Section 11.6, nothing in this
Agreement or any other Loan Documents, expressed or implied, is intended to or
shall confer on any Person other than the respective parties hereto and thereto
and their successors and assignees permitted hereunder and thereunder any
benefit or any legal or equitable right, remedy or other claim under this
Agreement or any other Loan documents.

     (i)  Notwithstanding anything in this Section 11.6 to the contrary, no
Eligible Assignee or Participant shall be entitled to receive any greater
payment under Section 2.15 or Section 9.3 than such assigning or participating
Lender would have been entitled to receive with respect to the interest assigned
or participated to such Eligible Assignee or Participant.

     Section 11.7   Counterparts. This Agreement may be executed in any number
                    ------------        
of counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

     Section 11.8   Severability. Any provision of this Agreement which is for
                    ------------        
any reason prohibited or found or held invalid or unenforceable by any court or
governmental agency shall be ineffective to the extent of such prohibition or
invalidity or unenforceability without invalidating the remaining provisions
hereof in such jurisdiction or affecting the validity or enforceability of such
provision in any other jurisdiction.

     Section 11.9   Interest and Charges.  It is not the intention of any 
                    --------------------                                  
parties to this Agreement to make an agreement in violation of the laws of any
applicable jurisdiction relating to usury. Regardless of any provision in any
Loan Documents, no Lender shall ever be entitled to receive, collect or apply,
as interest on the Obligations, any amount in excess of the Maximum Amount. If
any Lender or participant ever receives, collects or applies, as interest, any
such excess, such amount which would be excessive interest shall be deemed a
partial repayment of principal and treated hereunder as such; and if principal
is paid in full, any remaining excess shall be paid to the Borrower. In
determining whether or not the interest paid or payable, under any specific
contingency, exceeds the Maximum Amount, the Borrower and the Lenders shall, to
the maximum extent permitted under Applicable Law, (a) characterize any
nonprincipal payment as an expense, fee or premium rather than as interest, (b)
exclude voluntary prepayments and the effect thereof, and (c) amortize, prorate,
allocate and spread in equal parts, the total amount of interest throughout the

                                      -77-
<PAGE>
 
entire contemplated term of the Obligations so that the interest rate is uniform
throughout the entire term of the Obligations; provided, however, that if the
Obligations are paid and performed in full prior to the end of the full
contemplated term thereof, and if the interest received for the actual period of
existence thereof exceeds the Maximum Amount, the Lenders shall refund to the
Borrower the amount of such excess or credit the amount of such excess against
the total principal amount of the Obligations owing, and, in such event, the
Lenders shall not be subject to any penalties provided by any laws for
contracting for, charging or receiving interest in excess of the Maximum Amount.
This Section shall control every other provision of all agreements pertaining to
the transactions contemplated by or contained in the Loan Documents.

     Section 11.10  Headings. Headings used in this Agreement are for
                    --------      
convenience only and shall not be used in connection with the interpretation of
any provision hereof.

     Section 11.11  Amendment and Waiver.  The provisions of this Agreement or
                    --------------------      
 any other Loan Document may not be amended, modified or waived except by the
written agreement of the Borrower and the Determining Lenders; provided,
however, that no such amendment, modification or waiver shall be made (a)
without the consent of all Lenders, if it would (i) increase the Commitment or
the Specified Percentage of any Lender, or (ii) extend the date of maturity of,
extend the due date for any payment of principal or interest on, reduce the
amount of any installment of principal or interest on, or reduce the rate of
interest on, any Advance, the Reimbursement Obligations or other amount owing
under any Loan Documents, or (iii) release any security for or guaranty of the
Obligations (except pursuant to this Agreement), or (iv) reduce the fees payable
hereunder, or (v) revise this Section 11.11, or (vi) waive the date for payment
of any of the Obligations, or (vii) amend the definition of Determining Lenders
or otherwise alter the percentage of Lenders necessary to take action under any
of the Loan Documents; (b) without the consent of the Administrative Lender, if
it would alter the rights, duties or obligations of the Administrative Lender;
or (c) without the consent of the Issuing Bank, if it would alter the rights,
duties or obligations of the Issuing Bank. Neither this Agreement nor any term
hereof may be amended orally, nor may any provision hereof be waived orally but
only by an instrument in writing signed by the Administrative Lender and, in the
case of an amendment, by the Borrower.

     Section 11.12  Exception to Covenants.  Neither the Borrower nor any
                    ----------------------                               
Subsidiary shall be deemed to be permitted to take any action or fail to take
any action which is permitted as an exception to any of the covenants contained
herein or which is within the permissible limits of any of the covenants
contained herein if such action or omission would result in the breach of any
other covenant contained herein.

     Section 11.13  No Liability of Issuing Bank.  The Borrower assumes all 
                    ----------------------------                            
risks of the acts or omissions of any beneficiary or transferee of any Letter of
Credit with respect to its use of such Letter of Credit.  Neither the Issuing
Bank nor any Lender nor any of their respective officers or directors shall be
liable or responsible for:  (a) the use that may be made of any Letter of Credit
or any acts or omissions of any beneficiary or transferee in connection
therewith; (b) the validity, sufficiency or genuineness of documents, or of any
endorsement thereon, even if such documents 

                                      -78-
<PAGE>
 
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; (c) payment by the Issuing Bank against presentation of documents that
do not comply with the terms of a Letter of Credit, including failure of any
documents to bear any reference or adequate reference to the Letter of Credit,
except for any payment made upon the Issuing Bank's gross negligence or willful
misconduct; or (d) any other circumstances whatsoever in making or failing to
make payment under any Letter of Credit, except that the Borrower shall have a
                                         ------
claim against the Issuing Bank, and the Issuing Bank shall be liable to the
Borrower, to the extent of any direct, but not consequential, damages suffered
by the Borrower that the Borrower proves were caused by (i) the Issuing Bank's
willful misconduct or gross negligence in determining whether documents
presented under any Letter of Credit comply with the terms of the Letter of
Credit or (ii) the Issuing Bank's willful failure to make lawful payment under a
Letter of Credit after the presentation to it of a draft and certificates
strictly complying with the terms and conditions of the Letter of Credit. In
furtherance and not in limitation of the foregoing, the Issuing Bank may accept
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary.

     Section 11.14  Confidentiality.  Each Lender and the Administrative Lender
                    ---------------

that nothing herein shall limit the disclosure of any such information (a) to
the extent required by statute, rule, regulation or judicial process, (b) to
counsel for any Lender or the Administrative Lender, (c) to bank examiners,
auditors or accountants of any Lender, (d) to the Administrative Lender, any

(f) to the extent necessary in connection with the exercise of any remedy under
this Agreement or any other Loan Document; provided, further, that, unless
specifically prohibited by Applicable Law or court order, each Lender shall,
prior to disclosure thereof, notify the Borrower of any request for disclosure
of any such not-public information (i) by any governmental agency or
representative thereof (other than any such request in connection with an
examination of such Lender's financial condition by such governmental agency) or
(ii) pursuant to legal process, or (g) to any assignee or participant (or
prospective assignee or participant) so long as such assignee or participant (or
prospective assignee or participant) agrees to handle such information
confidentially.

                    ----------------------
