                              RMI TITANIUM COMPANY
 
              SELECTED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
NOTE 1--GENERAL
 
     The consolidated financial statements include the accounts of RMI Titanium
Company and its majority owned subsidiaries. All significant intercompany
transactions are eliminated. The Company's operations are conducted in one
business segment, the production and marketing of titanium metal and related
products.
 
     On July 3, 1997, the Company acquired 90% of the common stock of Galt
Alloys, Inc., a manufacturer of ferrotitanium and a producer and worldwide
distributor of specialty alloys to ferrous and nonferrous customers. RMI's
investment in Galt amounts to an initial cash investment of $3 million and an
agreement to invest up to an additional $17 million to finance a major expansion
program at Galt, which is expected to be completed in mid 1999. Through June 30,
1998, approximately $9.1 million had been expended on the expansion. Results of
Galt's operations are consolidated with RMI as of the acquisition date.
 
NOTE 2--ORGANIZATION
 
     The Company is a successor to entities that have been operating in the
titanium industry since 1958. In 1990, USX Corporation ("USX") and Quantum
Chemical Corporation ("Quantum") transferred their entire ownership interest in
the Company's immediate predecessor, RMI Company, an Ohio general partnership,
to the Company in exchange for shares of the Company's Common Stock (the
"Reorganization"). Quantum then sold its shares to the public. USX retained
ownership of its shares. At June 30, 1998 approximately 27% of the outstanding
common stock was owned by USX.
 
     In November, 1996, USX Corporation completed a public offering of its notes
which are exchangeable in February, 2000, for 5,483,600 shares of RMI Common
Stock, owned by USX (or for an equivalent amount of cash at USX's option). Such
shares represent all of the RMI Common Stock owned by USX.
 
NOTE 3--INCOME TAXES
 
     In the three and six month periods ended June 30, 1998 the Company recorded
an income tax benefit of $10.1 million and $4.0 million, respectively. These
amounts are comprised of an income tax provision against pretax income for the
three month period of $5.9 million and the six month period of $12.0 million and
an income tax benefit of $16.1 million for both periods, resulting from an
adjustment to reduce the deferred tax asset valuation allowance due to changes
in the Company's expectations about the ultimate realization of its deferred tax
assets. Excluding the $16.1 million valuation allowance adjustment, the
effective tax rate for the three months and the six months ended June 30, 1998
was approximately 29.0 percent. Because of available net operating loss
carryforwards, the amount of current taxes expected to be paid in 1998 will be
well below the level which could be expected by applying the statutory federal
tax rate of 35% to pretax income.
 
     Statement of Financial Accounting Standards No. 109 (SFAS No. 109),
"Accounting for Income Taxes," requires a valuation allowance when it is "more
likely than not" that some portion or all of the deferred tax assets will not be
realized. It further states that "forming a conclusion that a valuation
allowance is not needed is difficult when there is negative evidence such as
cumulative losses in recent years." The ultimate realization of this deferred
income tax asset depends upon the Company's ability to generate sufficient
taxable income prior to the expiration of its loss carryforwards. The Company
has evaluated the available evidence supporting the realization of future
taxable income and, based upon that evaluation, believes it is more likely than
not that its deferred tax assets will be realized. Based on that evaluation, the
valuation allowance was reduced.

NOTE 4--CONTINGENCIES
 
     In the ordinary course of business, the Company is subject to environmental
laws and regulations concerning the production, handling, storage,
transportation, emission, and disposal of waste materials and is also subject to
other federal and state laws and regulations regarding health and safety
matters. These laws and regulations are constantly evolving, and it is not
currently possible to predict accurately the ultimate effect these laws and
regulations will have on the Company in the future.
 
     The Company is involved in investigative or cleanup projects under federal
or state environmental laws at a number of waste disposal sites, including the
Fields Brook Superfund Site. Given the status of the proceedings with respect to
these sites, ultimate investigative and remediation costs cannot presently be
accurately predicted, but could, in the aggregate, be material. Based on the
information available regarding the current ranges of estimated remediation
costs at currently active sites, and what the Company believes will be its
ultimate share of such costs, provisions for environmental-related costs have
been recorded. These provisions are in addition to amounts which have previously
been accrued for the Company's share of environmental study costs.
 
     With regard to the Fields Brook Superfund Site, the Company, together with
31 other companies, has been identified by the EPA as a potentially responsible
party ("PRP") under the Comprehensive Environmental Response, Compensation
Liability Act ("CERCLA") with respect to a superfund site defined as the Fields
Brook Watershed in Ashtabula, Ohio, which includes the Company's now closed
Ashtabula facilities. The EPA's 1986 estimate of the cost of remediation of the
Fields Brook operable sediment unit was $48 million. Recent studies, together
with improved remediation technology and redefined cleanup standards have
resulted in a more recent estimate of the remediation cost of approximately $25
million. The actual cost of remediation may vary from the estimate depending
upon any number of factors.
 
     The EPA, beginning in March 1989, ordered 22 of the PRPs to conduct a
design phase study for the sediment operable unit and a source control study.
These studies are nearly complete. The Company, working cooperatively with
fourteen other PRPs in accordance with two separate agreements, is complying
with the order. The Company has accrued and has been paying its portion of the
cost of such compliance. Actual cleanup will not commence prior to 1999. The
Company's share of the study costs has been established at 9.95%. In June, 1995,
the Company and twelve other PRPs entered into a Phase 2 (actual cleanup)
allocation agreement which assigns 9.44% of the cost to RMI. However, the actual
percentage may be more or less based on contributions from other parties which
are not currently participating in the Phase 2 allocation agreement.
 
     At June 30, 1998, the amount accrued for future environmental-related costs
was $3.5 million. Based on available information, RMI believes its share of
potential environmental-related costs, before expected contributions from third
parties, is in a range from $4.2 million to $7.0 million, in the aggregate. The
amount accrued is net of expected contributions from third parties (which does
not include any amounts from insurers) of approximately $2.1 million, which the
Company believes are probable. The Company has been receiving contributions from
such third parties for a number of years as partial reimbursement for costs
incurred by the Company. As these proceedings continue toward final resolution,
amounts in excess of those already provided may be necessary to discharge the
Company from its obligations for these projects.
 
     The ultimate resolution of these foregoing contingencies could,
individually or in the aggregate, be material to the consolidated financial
statements. However, management believes that the Company will remain a viable
and competitive enterprise even though it is possible that these matters could
be resolved unfavorably.

NOTE 6--CREDIT AGREEMENT:
 
     The Company entered into a credit agreement dated June 8, 1998 (the "Credit
Facility"), to replace the Company's existing credit facilities. The unsecured
Credit Facility provides for $125 million in five-year borrowings and $25
million in one-year borrowings, on a revolving basis, of up to the lesser of
$150 million or a borrowing base equal to the sum of 85% of qualified accounts
receivable and 60% of qualified inventory. At June 30, 1998 no amounts were
outstanding under the facility.
 
     Under the terms of the Credit Facility, the Company, at its option, will be
able to borrow at (a) a base rate (which is the higher of PNC Bank's prime rate
or the Federal Funds Effective Rate plus 0.5% per annum), or (b) LIBOR, plus a
spread (ranging from 0.5% to 1.5%) determined by the ratio of the Company's
consolidated total indebtedness to consolidated earnings before interest, taxes,
depreciation and amortization.
 
     The Credit Facility contains additional terms and financial covenants which
are typical for other similar facilities.
 
NOTE 7--SUBSEQUENT EVENTS:
 
     On July 6, 1998, the Company signed a Letter of Intent to acquire Sierra
Alloys Company, Inc. (Sierra), of Irwindale, California, for a combination of
cash and stock. Sierra is a manufacturer of specialty metal products including
stainless and alloy steels, high temperature alloys and titanium. Sierra also
operates as a manufacturing service center providing forged and rolled products
to a number of markets including the aerospace, petrochemical, and medical
implant industries. Sierra's 1997 sales exceeded $50 million.
 
     On July 23, 1998, the Company signed a Letter of Intent to acquire New
Century Metals, Inc. (NCM), of Solon, Ohio. The letter agreement calls for NCM
to exchange all of its outstanding common shares for shares of RMI common stock.
NCM is a manufacturer and distributor of high temperature and corrosion
resistant alloys such as titanium, stainless steel and nickel, in long bar form,
to the aerospace, chemical processing, oil exploration and production, and power
generation industries. In addition to the manufacturing facilities, NCM operates
four distribution centers in the United States and one in England.
 
     These transactions are subject to, among other things, negotiation and
execution of mutually satisfactory definitive agreements, successful completion
of due diligence, the receipt of required regulatory clearances and other
customary pre-closing conditions.
 
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION
 
     The following discussion should be read in connection with the information
contained in the Consolidated Financial Statements and Selected Notes to
Consolidated Financial Statements. The following information contains
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995, and are subject to the safe harbor created by
that Act. Such forward-looking statements include, without limitation,
statements regarding the future availability and prices of raw materials, the
competitiveness of the titanium industry, demand for the Company's products, the
historic cyclicality of the titanium and aerospace industries, uncertain defense
spending, long-term supply agreements, the ultimate determination of pending
trade petitions, global economic conditions, the Company's order backlog and the
conversion of that backlog into revenue and other statements contained herein
that are not historical facts. Because such forward-looking statements involve
risks and uncertainties, there are important factors that could cause actual
results to differ
 
                                        9
<PAGE>   11
 
materially from those expressed or implied by such forward-looking statements.
These and other risk factors are set forth below in the "Outlook" section, as
well as being described in the Company's other filings with the Securities and
Exchange Commission ("SEC") over the last 12 months, copies of which are
available from the SEC or may be obtained upon request from the Company.
 
THREE MONTHS ENDED JUNE 30, 1998 COMPARED TO THREE MONTHS ENDED JUNE 30, 1997
 
NET SALES
 
     Net sales increased to $96.5 million, or 29% for the three months ended
June 30, 1998 compared to net sales of $75.0 million in the corresponding 1997
period. This sales increase is due primarily to increased average selling prices
for titanium mill products, and a shift in product mix to more value added
products such as sheet and plate, and away from commodity type products such as
billet and bloom. Shipments of titanium mill products were 4.9 million pounds in
the second quarter of 1998 compared to 4.6 million pounds for the same period in
1997 despite a three week outage at the Company's rolling mill in April 1998.
Average selling prices on mill products in the second quarter of 1998 increased
by approximately 4% to $14.57 per pound from $14.02 per pound in the second
quarter of 1997. The increase in sales over the second quarter of 1997 is also
partially due to $5.4 million in sales generated by Galt Alloys, Inc. Galt was
acquired in July, 1997.
 
GROSS PROFIT
 
     Gross profit amounted to $24.2 million, or 25.0% of sales for the quarter
ended June 30, 1998 compared to a gross profit of $16.7 million or 22.3% for the
comparable 1997 period. This improvement results primarily from increased profit
margins on titanium mill products resulting from a more favorable product mix
and higher average selling prices.
 
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
     Selling, general and administrative expenses amounted to $3.8 million for
the quarter ended June 30, 1998 compared to $2.8 million for the same quarter in
1997. This increase results primarily from increased business levels. Research,
technical and product development expenses amounted to $1.0 million in the
second quarter of 1998 compared to $0.7 million in the second quarter of 1997.
Selling, general and administrative expenses together with research, technical
and product development expenses amounted to approximately 5.0% of sales in the
second quarter of 1998 compared to 4.7% of sales in the comparable 1997 period.
 
OPERATING INCOME
 
     Operating income for the three months ended June 30, 1998 amounted to $19.4
million, or 20.1% of sales compared to $13.2 million or 17.6% of sales in the
same period of 1997. This improvement results primarily from increased profit
margins on mill products.
 
INCOME TAXES
 
     In the second quarter of 1998, the Company recorded an income tax benefit
of $10.1 million compared to a $1.4 million provision recorded in the second
quarter of 1997. Included in the three month period ended June 30, 1998 is a
$16.1 million benefit resulting from an adjustment to the deferred tax asset
valuation allowance due to changes in the Company's expectations about the
ultimate realization of its deferred tax assets in years after 1998. Exclusive
of this adjustment, the effective federal tax rate for the second quarter of
1998 was approximately 29.0%. The effective federal tax rate for the second
quarter of 1997 was approximately 10.1%. The difference between the statutory
tax rate of 35% and the effective tax rate for both the second quarter of 1998
and 1997 is primarily due to adjustments to the deferred tax asset valuation
allowance as it related to expected current year results. Because of available
net operating loss carry forwards, the amount of current taxes expected to be
paid in 1998 will be well below the level which could be expected by applying
the statutory federal tax rate of 35% to pretax income. See "Income Tax
Considerations" and "SFAS No. 109 Effects" below.
 
                                       10
<PAGE>   12
 
OTHER INCOME
 
     Other income for the second quarter of 1998 amounted to $0.9 million
compared to $0.3 million for the same period in 1997. This increase results
primarily from increased investment income on short term securities.
 
NET INCOME
 
     Net income for the quarter ended June 30, 1998 amounted to $30.4 million or
31.5% of sales compared to $12.0 million, or 16.1% of sales in the comparable
1997 period. This increase is due primarily to increased margins on titanium
mill products and the deferred tax credit referred to above.
 
SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO SIX MONTHS ENDED JUNE 30, 1997
 
NET SALES
 
     Net sales for the six months ended June 30, 1998 increased to $185.6 from
$148.7 million in the first six months of 1997, an increase of $36.8 million, or
24.8%. This increase results primarily from higher average selling prices and
increased mill product shipments. Mill products shipments for the first six
months of 1998 amounted to 9.8 million pounds compared to 9.4 million pounds in
the comparable period of 1997 despite a three week outage at the Company's
rolling mill in April 1998. Average realized selling prices increased to $14.82
per pound in the first six months of 1998 compared to $13.88 per pound in 1997.
The higher average selling prices in the first six months of 1998 compared to
the second quarter is due primarily to shipping less value added flat product as
a result of the rolling mill outage in the second quarter. The increase in sales
from 1997 is also partially due to $10.5 million in sales generated by Galt
Alloys, Inc. Galt was acquired in July, 1997.
 
GROSS PROFIT
 
     Gross profit for the six months ended June 30, 1998 amounted to $49.7
million, or 26.8% of sales compared to $32.5 million, or 21.8% of sales in the
first six months of 1997. This increase results primarily from increased selling
prices for titanium mill products and increased volume.
 
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
     Selling, general and administrative expenses amounted to $7.8 million for
the first six months of 1998 compared to $5.5 million for the comparable period
in 1997. This increase results primarily from increased business levels.
Research, technical and product development expenses amounted to $1.8 million,
and $1.4 million in the six month periods ended June 30, 1998 and 1997,
respectively. Selling, general and administrative expenses together with
research, technical and product development expenses for the first six months of
1998 amounted to 5.2% of sales compared to 4.7% of sales in the first six months
of 1997.
 
OPERATING INCOME
 
     Operating income for the six months ended June 30, 1998 amounted to $40.1
million, or 21.6% of sales compared to $25.6 million, or 17.4% of sales in the
same period of 1997. This improvement results primarily from increases in
average realized selling prices and mill product shipments.
 
INCOME TAXES
 
     In the first six months of 1998, the Company recorded an income tax benefit
of $4.0 million compared to a $2.9 million provision recorded in the first six
months of 1997. The income tax benefit of $4.0 million recorded in the first six
months of 1998 is comprised of an income tax provision of $12.1 million and an
income tax benefit of $16.1 million resulting from an adjustment to reduce the
deferred tax asset valuation allowance due to changes in the Company's
expectations about the ultimate realization of its deferred tax assets.
Exclusive of this adjustment, the effective federal tax rate for the six months
ended June 30, 1998 was approximately 29.0% compared to 11.3% for the same
period in 1997. The difference between the statutory tax rate of 35% and the
effective tax rate for the six month periods ending June 30, 1998 and 1997 is
primarily due
 
                                       11
<PAGE>   13
 
to adjustments to the deferred tax asset valuation allowance related to expected
current year results. Because of available net operating loss carryforwards, the
amount of current taxes expected to be paid in 1998 will be well below the level
which could be expected by applying the statutory federal tax rate of 35% to
pretax income. See "Income Taxes" and "SFAS No. 109 Effects" below.
 
NET INCOME
 
     Net income for the six months ended June 30, 1998 amounted to $45.5
million, or 24.5% of sales compared to $23.0 million, or 15.5% of sales in the
first six months of 1997. This increase is due primarily to increased profit
margins on titanium mill products and the deferred tax credit referred to above.
 
OUTLOOK
 
     During the last three years, and continuing into early 1998, the U.S.
titanium industry has experienced a significant increase in demand and pricing
for titanium mill products. This increase in demand has resulted primarily from
an unprecedented increase in demand from the commercial aerospace markets.
During the 1995-1997 period, most commercial airlines have reported stronger
operating profits. In order to meet increasing passenger load demands and the
need to replace older, less efficient aircraft, commercial airlines placed
orders for new and replacement aircraft at near record levels, and the leading
manufacturers of commercial aircraft announced increased build and delivery
rates for certain aircraft. Recently, Boeing Commercial Airplane Group made
several announcements reducing its forecasted production rates on a number of
wide body aircraft models in the 1999-2000 time frame. Other aerospace
contractors have announced some delivery delays and rescheduling resulting from
the Boeing announcements, and a need to adjust inventory requirements downward
from peak levels. While the company has not experienced significant order
cancellations or rescheduling, pricing on incoming orders has shown some
softening particularly in the nonvalue added commodity products such as ingot
and bloom. Demand and pricing for the Company's core value added products, alloy
sheet and plate, remain relatively strong. This slowing in the growth of
commercial aircraft build rates will impact the overall demand for titanium mill
products. The Company anticipates the balance of 1998 to remain strong both in
terms of mill product shipments and profitability. RMI can give no assurances as
to the extent or duration of demand in the commercial aerospace market.
 
     During the second quarter of 1998, RMI was named by B.F. Goodrich Aerospace
Aerostructures Group, which designs and manufactures engine nacelle systems for
large commercial and military aerospace applications, as its principal supplier
of alloy sheet. During the same period, RMI secured contracts with Contrucciones
Aeronauticas S.A. (CASA) of Spain and Daimler-Benz Aerospace AG of Germany for
their alloy plate and sheet requirements in connection with the Airbus and
Eurofighter programs. All three contracts, totaling more than $60 million, begin
in 1999 and extend for a minimum of three years.
 
     Also, during the second quarter of 1998, RMI was designated the sole
supplier of titanium mill products for the Air Force F-22 fighter being built by
Lockheed Martin and Boeing. The new contract, which begins this year, will
continue through the life of the program with approximately 339 aircraft
forecast to be produced by the year 2012. The value of this contract could
potentially total $340 million.
 
     On February 2, 1998, RMI entered into an agreement with Boeing Commercial
Airplane Group whereby RMI will supply Boeing and its family of commercial
suppliers with up to 4.5 million pounds of titanium products annually. The
agreement, beginning in 1999, will have an initial term of five years and,
subject to review by the parties in the fourth year, could be extended for an
additional five years. Under the accord, Boeing will receive firm prices in
exchange for RMI receiving a minimum volume commitment of 3.25 million pounds
per year, or approximately 50% of the Company's current supply levels to Boeing.
 
     RMI has also been selected by military aircraft producers Boeing and
Northrop as their principal supplier of titanium alloy plate and alloy sheet
including just-in-time, cut-to-size products, for the C-17 Transport, F-15 Eagle
and the F/A-18 Hornet programs. The Hornet program includes the new E/F version
which utilizes considerably more titanium than earlier C/D models. The agreement
will begin with May 1999 requirements and runs through April 2001.
 
                                       12
<PAGE>   14
 
     In another accord, RMI, through its French affiliate, Reamet, has been
chosen by Aerospatiale as the major supplier of the titanium flat rolled
products required for its Airbus programs beginning in 1999 and extending
through 2001. Requirements are principally for flat-rolled products, including
value added cut-to-size shapes.
 
     The Company's total order backlog as of June 30, 1998 was approximately
$368 million, compared to $383 million at December 31, 1997.
 
     Beginning in the second half of 1995 and continuing into 1998, the Company
has experienced a significant increase in the volume of incoming orders at
improving prices. The Company estimates that as of June 30, 1998, orders for
substantially all of its anticipated 1998 shipments have been booked or shipped
at average prices greater than its 1997 average realized mill product selling
price of $14.23 per pound. The Company's average realized mill product selling
price increased to $14.82 per pound in the first six months of 1998 compared to
$13.88 per pound in the first six months of 1997. The Company is currently
booking orders for titanium mill products for delivery in the first half of
1999.
 
     Because of the titanium industry's long-term supply and pricing
arrangements with Boeing and others and the announced changes in aircraft build
rates as discussed above, aerospace customers have become more resistant to
significant price increases. While the Company expects higher average selling
prices for 1998 when compared to the same period in 1997, mill product pricing
is generally beginning to flatten as a result of these long-term arrangements as
well as the slowing of the growth in commercial aircraft build rates.
 
     Prices for the Company's 1998 titanium sponge requirements have been set
under long-term supply contracts and short-term arrangements. In the aggregate,
the Company expects average prices for titanium sponge purchases in 1998 to
approximate 1997 levels. Negotiations covering 1999 sponge requirements and
pricing levels are currently underway. Due to the increase in demand for
titanium mill products, overall demand for titanium scrap, which accounts for
approximately 40% of the Company's raw material requirements has also increased.
However, because of increased supplies of titanium scrap, prices for scrap have
eased somewhat. Prices of certain alloying agents have increased as a result of
increased demand. The Company has announced increased prices and the
implementation of metallic surcharges to recover increased raw material costs,
although there can be no assurances that the Company will continue to be able to
recover these costs.
 
LABOR RELATIONS
 
     United Steelworkers of America ("USWA") represents the production and
maintenance as well as the clerical and technical employees at the Company's
main production facility at Niles, Ohio. The current three year labor agreement
with the USWA expires on September 30, 1998. Negotiations for a new contract
have begun, and the Company is hopeful of reaching a mutually satisfactory
agreement prior to expiration of the current contract.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Net cash flows from operating activities totaled $21.7 million in the first
six months of 1998 compared to $15.9 million in the first six months of 1997.
The change in net cash flows from operating activities in the first six months
of 1998, compared to the comparable 1997 period was due primarily to
significantly improved results of operations. Working capital amounted to $205.2
million at June 30, 1998, compared to $184.8 million at December 31, 1997. The
increase in working capital results primarily from increases in cash and
inventory. The Company's working capital ratio was 5.3 to 1 at June 30, 1998.
 
     During the first six months of 1998 and the comparable 1997 period, the
Company's cash flow requirements for capital expenditures were funded by cash
provided from operating activities.
 
     The Company anticipates that it will be able to fund its 1998 working
capital requirements and its capital expenditures from funds generated by
operations. The Company's long-term liquidity requirements, including capital
expenditures, are expected to be financed by a combination of internally
generated funds, borrowings and other sources of external financing if needed.
                                       13

     Credit Agreement. The Company entered into a credit agreement, dated June
8, 1998 (the "Credit Facility"), to replace the Company's existing credit
facilities. The unsecured Credit Facility provides for $125 million in five-year
borrowings and $25 million in one-year borrowings, on a revolving basis, of up
to the lesser of $150 million or a borrowing base equal to the sum of 85% of
qualifying accounts receivable and 60% of qualifying inventory. At June 30, 1998
no amounts were outstanding under the facility. Under the terms of the Credit
Facility, the Company, at its option will be able to borrow at (a) a base rate
(which is the higher of PNC Bank's prime rate or the Federal Funds Effective
Rate plus 0.5% per annum), or (b) LIBOR plus a spread (ranging from 0.5% to
1.5%) determined by the ratio of the Company's consolidated total indebtedness
to consolidated earnings before interest, taxes, depreciation and amortization.
 
INCOME TAXES
 
     SFAS No. 109 Effects. SFAS 109 requires a valuation allowance when it is
more likely than not that some portion or all of the deferred tax assets will
not be realized. It further states that forming a conclusion that a valuation
allowance is not needed is difficult when there is negative evidence such as
cumulative losses in recent years. The ultimate realization of all or part of
the Company's deferred income tax assets depends on the Company's ability to
generate sufficient taxable income in the future.
 
     When preparing interim and annual financial statements, the Company
periodically evaluates its strategic and business plans, in light of evolving
business conditions, and the valuation allowance is adjusted for future income
expectations resulting from that process, to the extent different from those
inherent in the current valuation allowance. In making an assessment of
realizability at June 30, 1998, the Company considered a number of factors
including the improved profitability in 1998 as a result of increased sales,
product pricing and gross margins, as well as the improved outlook for periods
beyond 1998, when compared to expectations inherent in the December 31, 1997
valuation allowance. Accordingly, the valuation allowance was reduced to reflect
the revised future income expectations. The remaining valuation allowance at
June 30, 1998 relates to deferred tax assets for tax loss carryforwards. These
assets are expected to be realized in 1998. Therefore, pursuant to the
provisions of Accounting Principles Board Opinion No. 28, "Interim Financial
Reporting" and SFAS No. 109, the remaining allowance will be released through
the effective tax rate in the second half of the year.
 
     At December 31, 1997, approximately $16 million of the available net
operating loss carryforwards had not yet been recognized for SFAS 109 purposes.
The valuation allowance relating to net operating loss carryforwards was
recognized in the effective rate calculation for the six months ended June 30,
1998, resulting in an effective book tax rate below the statutory federal rate
of 35%. As a result of this, the entire amount of the Company's net operating
loss carryforwards will be utilized for SFAS 109 purposes in 1998.
 
     For federal income tax return purposes, the amount of remaining net
operating loss carryforwards at December 31, 1997 amounted to approximately $43
million, which are available to offset future taxable income. Because the
Company expects to generate sufficient taxable income, the currently available
net operating loss carryforwards will be fully utilized in 1998. Because of the
availability of these net operating loss carryforwards to offset taxable income,
actual cash payments for federal income taxes in 1998 will be well below the
level which could be expected by applying the statutory federal tax rate of 35%
to pretax income.
 
ENVIRONMENTAL MATTERS
 
     The Company is subject to environmental laws and regulations as well as
various health and safety laws and regulations that are subject to frequent
modifications and revisions. While the costs of compliance for these matters
have not had a material adverse impact on RMI in the past, it is impossible to
predict accurately the ultimate effect these changing laws and regulations may
have on the Company in the future.
 
     At June 30, 1998, the amount accrued for future environment-related costs
was $3.5 million. Based on available information, RMI believes its share of
potential environmental-related costs, before expected contributions from third
parties, is in a range from $4.2 million to $7.0 million, in the aggregate. The
amount accrued is net of expected contributions from third parties (which does
not include any amounts from insurers) of approximately $2.1 million, which the
Company believes are probable. The Company has received
                                       14
<PAGE>   16
 
contributions from such third parties for a number of years as partial
reimbursement for costs incurred by the Company. As these proceedings continue
toward final resolution, amounts in excess of those already provided may be
necessary to discharge the Company from its obligations for these projects.
 
     The ultimate resolution of these environmental matters could individually,
or in the aggregate, be material to the consolidated financial statements.
However, management believes that the Company will remain a viable and
competitive enterprise even though it is possible that these matters could be
resolved unfavorably.
 
CAPITAL EXPENDITURES
 
     Gross capital expenditures the first six months of 1998 and 1997 amounted
to $11.3 and $1.9 million, respectively. The Company has anticipated capital
spending of approximately $30 to $35 million in 1998. RMI anticipates that
current capital spending plans can be funded using cash provided from internally
generated sources.
 
NEW ACCOUNTING STANDARDS
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income". The Company adopted SFAS No. 109 in the first quarter of 1998. Although
this standard requires new reporting for comprehensive income, it does not
impact the measurement of comprehensive income, and, as such, has not had a
material impact on the reported results of operations or financial position.
 
     Also in June 1997, the FASB issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." The Company expects to adopt
this standard in its annual financial statements for 1998, but has not yet
completed its evaluation of the impact of this standard. However, since this
standard requires disclosure of additional information but does not prescribe
new measurement standards, the Company does not expect the adoption of this
standard to have a material impact on the reported results of operations or
financial position.
 
     In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits--an amendment of FASB
Statements No. 87, 88, and 106." This Statement revises employers' disclosures
about pension and other postretirement benefit plans. It does not change the
measurement or recognition of those plans. The Company expects to adopt the
provisions of this standard in its annual financial statements for 1998, and
does not expect this disclosure-only standard to have a significant impact on
reported results of operations or financial position.
 
     In March 1998, the Accounting Standards Executive Committee of the AICPA
issued Statement of Position 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." The principles established in
this statement are required to be applied to the Company's financial statements
in 1999. Management has not yet completed its evaluation of the impact of this
standard on the Company's reported results of operations or financial position.
 
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes standards for
accounting and reporting of derivative financial instruments. The standard is
required to be adopted in 2000. Management has not yet evaluated the impact this
standard will have on reported results of operations or financial position.
 
YEAR 2000 COMPLIANCE
 
     The Company has and will continue to make certain investments in its
application software to ensure the Company is Year 2000 compliant. In addition,
the Company is monitoring the compliance efforts of entities with which it
interacts. The Company began modification of its internally developed
proprietary software in 1996 and currently estimates that approximately 90% of
this software has been modified and tested to make it Year 2000 compliant. The
balance is currently being modified and is expected to be completed in the first
half of 1999. In any event, many of the Company's internally generated software
programs are considered noncritical applications which can, if necessary, be
performed manually. Noninformation technology systems
                                       15
<PAGE>   17
 
such as process control devices and other automated equipment which may contain
imbedded chips that could be affected by the year 2000 problem have been
identified. Modifications to these devices are underway, and the Company
estimates that necessary modifications will be completed in the first quarter of
1999. The Company has also contacted its key vendors, suppliers and service
providers such as financial institutions to monitor their compliance efforts.
While it is not possible at present to accurately estimate the incremental cost
of this effort, the Company does not anticipate it will have a material impact
on the long-term results of operations, liquidity or consolidated financial
position of the Company. This discussion of RMI's efforts and management's
expectations relating to the effect of Year 2000 compliance on operating results
are forward looking statements. RMI's ability to achieve Year 2000 compliance
and the level of incremental costs associated therewith could be adversely
impacted by, among other things, the availability and cost of programming and
testing resources, vendors' ability to modify proprietary software and
unanticipated problems identified in the ongoing compliance review. In addition,
RMI has limited or no control over the actions of proprietary software vendors
and other entities with which it interacts. Therefore, Year 2000 compliance
problems experienced by these entities could adversely affect the results of the
Company.
 
ACQUISITIONS
 
     On July 6, 1998, the Company signed a Letter of Intent to acquire Sierra
Alloys Company, Inc. (Sierra), of Irwindale, California, for a combination of
cash and stock. Sierra is a manufacturer of specialty metal products including
stainless and alloy steels, high temperature alloys and titanium. Sierra also
operates as a manufacturing service center providing forged and rolled products
to a number of markets including the aerospace, petrochemical, and medical
implant industries. Sierra's 1997 sales exceeded $50 million.
 
     On July 23, 1998, the Company signed a Letter of Intent to acquire New
Century Metals, Inc. (NCM), of Solon, Ohio. The letter agreement calls for NCM
to exchange all of its outstanding common shares for shares of RMI common stock.
NCM is a manufacturer and distributor of high temperature and corrosion
resistant alloys such as titanium, stainless steel and nickel, in long bar form
to the aerospace, chemical processing, oil exploration and production, and power
generation industries. In addition to the manufacturing facilities, NCM operates
four distribution centers in the United States and one in England.
 
     These transactions are subject to, among other things, negotiation and
execution of mutually satisfactory definitive agreements, successful completion
of due diligence, the receipt of required regulatory clearances and other
customary pre-closing conditions. Depending on the extent and timing of these
items the Company currently plans on closing the NCM aquisition during the third
quarter of 1998, and the Sierra acquisition in the third or fourth quarter. Any
cash required for these acquisitions will be provided from internally generated
sources, supplemented as required by borrowings under the new credit agreement.

this Agreement, all computations and determinations as to accounting or

                                   ARTICLE II
                            REVOLVING CREDIT FACILITY

                  2.01. Revolving Credit Commitments. Subject to the terms and
conditions hereof and relying upon the representations and warranties herein set
forth, each Lender severally agrees to make revolving credit loans (the
"REVOLVING CREDIT LOANS") to the Borrower at any time or from time to time on or
after the date hereof to, but not including, the Expiration Date, provided that
the aggregate principal amount of each Lender's Revolving Credit Loans
outstanding hereunder to the Borrower shall not exceed at any one time such
Lender's Ratable Share of the aggregate Revolving Credit Commitments or the
Borrowing Base, whichever is less, minus such Lender's Ratable Share of the sum
of (i) the Swingline Loans outstanding, (ii) the aggregate Stated Amount of
outstanding Letters of Credit and (iii) the aggregate amount of Unreimbursed L/C
Draws. Within such limits of time and amount and subject to the other provisions
of this Agreement, the Borrower may borrow, repay and reborrow pursuant to this
Section 2.01. The aggregate amount of the Revolving Credit Commitments on the
Closing Date is $150,000,000. The Revolving Credit Commitment is divided into a
Long-Term Revolving Credit Commitment of $125,000,000 and a Short-Term Revolving
Credit Commitment of $25,000,000. All Long-Term Revolving Credit Commitments
shall expire on the Long-Term Expiration Date; and all Long-Term Revolving
Credit Loans outstanding on the Long-Term Expiration Date shall become due and
payable in full on such date. All Short-Term Revolving Credit Commitments shall
expire on the Short-Term Expiration Date; and all Short-Term Revolving Credit
Loans outstanding on the Short-Term Expiration Date shall become due and payable
in full on such date.

                  2.02. Nature of Lenders' Obligations with Respect to Revolving
Credit Loans. Each Lender shall be obligated to participate in each request for
Revolving Credit Loans pursuant to Section 2.05 hereof in accordance with its
Ratable Share. The aggregate principal amount of each Lender's Revolving Credit
Loans outstanding hereunder to the Borrower at any time shall never exceed such
Lender's Ratable Share of the aggregate Revolving Credit Commitments or the
Borrowing Base, whichever is less, minus such Lender's Ratable Share of the sum
of (i) Swingline Loans outstanding, (ii) the aggregate Stated Amount of
outstanding Letters of Credit and (iii) the aggregate amount of Unreimbursed L/C
Draws. The obligations of each Lender hereunder are several. The failure of any
Lender to perform its obligations hereunder shall not affect the obligations of
the Borrower, or any other Lender, to any other party nor shall the Borrower, or
any other Lender, be liable for the failure of such Lender to perform its
obligations hereunder. The Lenders shall have no obligation to make Revolving
Credit Loans hereunder on or after the relevant Expiration Date.

                  2.03.    Commitment Fees

                           (a)      Long-Term Commitment Fee.  Accruing from the
Closing Date until the Long-Term Expiration Date, the Borrower agrees to pay to
the Agent for the account of each Lender, as consideration for such Lender's
Long-Term Revolving Credit Commitment hereunder, a commitment fee (the
"LONG-TERM COMMITMENT FEE") equal to the Long-Term Applicable Commitment Fee per
annum, as determined below, (all computed on the basis of a year of 365 or 366
days, as the case may be, and actual days elapsed) on the average daily amount
equal to such Lender's Long-Term Revolving Credit Commitment minus such Lender's
Ratable Share of Total Utilization relating to its Long-Term Revolving Credit
Commitment. For the purposes of calculating the Long-Term Commitment Fee, the
amount outstanding under the Swingline Loans shall not be included in
calculating any Lender's Ratable Share of Total Utilization relating to its
Long-Term Revolving Credit Commitment.

                           (b)      Short-Term Commitment Fee.  Accruing from 
the Closing Date until the Short-Term Expiration Date, the Borrower agrees to
pay to the Agent for the account of each Lender, as consideration for such
Lender's Short-Term Revolving Credit Commitment hereunder, a commitment fee (the
"SHORT-TERM COMMITMENT FEE") equal to the Short-Term Applicable Commitment Fee
per annum, as determined below, (all computed on the basis of a year of 365 or
366 days, as the case may be, and actual days elapsed) on the average daily
amount equal to such Lender's Short-Term Revolving Credit Commitment minus such
Lender's Ratable Share of Total Utilization relating to the Short-Term Revolving
Credit Commitment. For purposes of calculating the Short-Term Commitment Fee,
the amount outstanding under the Swingline Loan shall not be included in
calculating any Lender's Ratable Share of Total Utilization relating to the
Short-Term Revolving Credit Commitment.

                           (c)      Applicable Commitment Fee.  For purposes of
this Agreement, the terms "LONG-TERM APPLICABLE COMMITMENT FEE" and "SHORT-TERM
APPLICABLE COMMITMENT FEE" shall mean the rate per annum set forth in the chart
below which corresponds to the range of ratios in which the Borrower's
Consolidated Total Indebtedness to Consolidated EBITDA Ratio, as at the end of
the preceding fiscal quarter, falls:

</TABLE>

All such adjustments shall be determined as of the date the Borrower's quarterly
financial . statements and Compliance Certificate are required to be delivered
to the Lenders pursuant to items (i) and (iii) of Section 6.02. The foregoing
notwithstanding, (i) the Long-Term Applicable Commitment Fee from the Closing
Date to and including the June 1998 Delivery 



                                     - 25 -

Date shall be .20%, and (ii) the Short-Term Applicable Commitment Fee from the
Closing Date to and including the June 1998 Delivery Date shall be .10%. All
Commitment Fees shall be payable (i) quarterly in arrears beginning June 30,
1998, and continuing on the last Business Day of each Fiscal Quarter occurring
during the term of the Long-Term Revolving Credit Commitment or the Short-Term
Revolving Credit Commitment, as appropriate, (ii) upon the relevant Expiration
Date and (ii) upon acceleration of the Notes.

                  2.04.    Reduction, Extension of Revolving Credit Commitment

                           (a)      Voluntary Reduction of Revolving Credit 
Commitments. Subject to the provisions of Section 2.09 hereof, at any time and
from time to time upon at least five (5) Business Days' prior written notice to
the Agent, the Borrower may terminate, in whole or in part, without penalty, the
then unused portion of the Revolving Credit Commitments, thereby causing a
corresponding abatement of the Commitment Fee. Each such reduction shall be in a
minimum principal amount of $5,000,000 or, if in excess of $5,000,000, in
integral multiples of $1,000,000. The Commitment Fee shall cease to accrue with
respect to any unused portion of the Revolving Credit Commitments so terminated
five (5) Business Days after receipt of such notice. Notice of termination once
given shall be irrevocable and the portion of the Revolving Credit Commitments
so terminated shall not be available for borrowing once such notice has been
given under the terms hereof. The Agent shall promptly notify each Lender of its
Ratable Share of such terminated unused portion and the date of each such
termination. The foregoing notwithstanding, the Short-Term Revolving Credit
Commitment must be reduced to zero and terminated before there may be any
reduction of the Long-Term Revolving Credit Commitment.

                           (b)      Extension of Short-Term Revolving Credit 
Commitment. The Borrower, during the period April 15 through April 30, 1999, and
during each subsequent period of April 15 through April 30 to and including the
period April 15 through April 30, 2002, during which time the Short-Term
Revolving Credit Commitment is in effect, may request renewal of the Short-Term
Revolving Credit Commitment for a period of one year for the period beginning
June 1 and ending May 31. Such request shall be made by a written notice,
executed by an Authorized Officer and delivered to the Agent. The Agent, upon
receiving such notice, shall promptly notify the Lenders. If all of the Lenders
agree in writing to the request to extend the Short-Term Revolving Credit
Commitment, (i) it shall be extended for a one year period of June 1 to May 31,
and (ii) the Agent shall so inform the Borrower and the Lenders in writing. The
failure to request the extension of the Short-Term Revolving Credit Commitment
or the refusal of the Lenders to grant any such extension shall result in the
scheduled termination of the Short-Term Revolving Credit Commitment and
automatically eliminate the Borrower's privilege to request the extension of the
Short-Term Revolving Credit Commitment in any subsequent year.

                  2.05. Revolving Credit Loan Requests. Except as otherwise
provided herein, the Borrower may from time to time prior to the relevant
Expiration Date request the Lenders to make Revolving Credit Loans to the
Borrower by the delivery to the Agent, not later than noon (Pittsburgh,
Pennsylvania time) (i) three (3) Business Days prior to the proposed Borrowing
Date with respect to the making of Revolving Credit Loans to which the Euro-Rate

Option applies for any Revolving Credit Loans; and (ii) on the Business Day of
the proposed Borrowing Date with respect to the making of a Revolving Credit
Loan to which the Base Rate Option applies of a duly completed request therefor
substantially in the form of Exhibit "D" hereto or a request by telephone
immediately confirmed in writing by letter or facsimile in such form (each, a
"LOAN REQUEST"), it being understood that the Agent may rely on the authority of
any person making such a telephonic request without the necessity of receipt of
such written confirmation. Each Loan Request shall be irrevocable and shall
specify (i) the proposed Borrowing Date; (ii) the aggregate amount of the
proposed Revolving Credit Loans to be made on such Borrowing Date, which amount,
as to Base Rate Portions, shall be in integral multiples of $500,000 and not
less than $1,000,000 and, as to Euro-Rate Portions, shall be in integral
multiples of $1,000,000 and not less than $5,000,000; (iii) subject to Section
2.08(d), whether the Euro-Rate Option or the Base Rate Option shall apply to the
proposed Revolving Credit Loans to be made on such Borrowing Date; and (iv) in
the case of Revolving Credit Loans to which the Euro-Rate Option applies and
subject to Sections 2.08(d) and 2.08(e), an appropriate Euro-Rate Interest
Period for each Euro-Rate Portion of the Revolving Credit Loans to be made on
such Borrowing Date. The Borrower may request disbursements of Short-Term
Revolving Credit Loans only when the full amount of Long-Term Revolving Credit
Commitment is utilized.

                  2.06. Making Revolving Credit Loans. Subject to Section 9.03,
the Agent shall, promptly after receipt by it of a Loan Request pursuant to
Section 2.05 (but not later than noon (Pittsburgh, Pennsylvania time) on the
Borrowing Date for same day funding and 2:00 p.m. (Pittsburgh, Pennsylvania
time) on the second Business Day preceding any Borrowing Date for which any
Portion of the Revolving Credit Loans to be made on such Borrowing Date bears
interest at the Euro-Rate Option), notify the Lenders of its receipt of such
Loan Request specifying: (i) the proposed Borrowing Date and the time and method
of disbursement of such Revolving Credit Loan; (ii) the amount and type of such
Revolving Credit Loan and the applicable Euro-Rate Portions and Euro-Rate
Interest Periods (if any); and (iii) the apportionment among the Lenders of the
Revolving Credit Loans as determined by the Agent in accordance with Section
2.02 hereof. Subject to Section 9.03, each Lender shall remit the principal
amount of each Revolving Credit Loan to the Agent such that the Agent is able
to, and the Agent shall, to the extent the Lenders have made funds available to
it for such purpose, fund such Revolving Credit Loan to the Borrower in Dollars
and immediately available funds at the Principal Office prior to 2:00 P.M.
(Pittsburgh, Pennsylvania time) on the Borrowing Date, provided that if any
Lender fails to remit such funds to the Agent in a timely manner, or any Lender
fails to advise the Agent of its intention not to fund, then the Agent may elect
in its sole discretion to fund with its own funds the Revolving Credit Loan of
such Lender on the Borrowing Date.

                  2.07. Notes. The obligation of the Borrower to repay the
aggregate unpaid principal amount of the Long-Term Revolving Credit Loans made
to the Borrower by each Lender, together with interest thereon, shall be
evidenced by a promissory note of the Borrower dated the Closing Date in
substantially the form attached hereto as Exhibit "A-1" payable to the order of
each Lender in a face amount equal to the Long-Term Revolving Credit Commitment
of such Lender. The obligation of the Borrower to repay the aggregate unpaid
principal amount of the Short-Term Revolving Credit Loans made to the Borrower
by

each Lender, together with interest thereon, shall be evidenced by a promissory
note of the Borrower dated the Closing Date in substantially the form attached
hereto as Exhibit "A-2", payable to the order of each Lender in a face amount
equal to the Short-Term Revolving Credit Commitment of such Lender.

                  2.08.    Interest Payments, Interest Rates and Certain Related
Payments Pertaining to the Revolving Credit Loans.

                           (a)      Interest. The Revolving Credit Notes shall 
bear interest on the actual unpaid principal amount thereof from time to time
outstanding from the date thereof until payment in full at the rates of interest
set forth in Section 2.08(b). The Borrower shall pay accrued interest on the
unpaid principal balance of the Revolving Credit Notes in arrears:

                                    (i)     with respect to the Base Rate 
Portion, at the rate specified in the Base Rate Option, (A) on the last Business
Day of each Fiscal Quarter during the term of the Revolving Credit Commitment,
(B) at maturity, whether by acceleration or otherwise, of the Revolving Credit
Notes and (C) thereafter on demand until all amounts evidenced by the Revolving
Credit Notes are paid in full; and

                                    (ii)    with respect to each Euro-Rate 
Portion, at the rate specified in the Euro-Rate Option, (A) on the last day of

months, interest on that Euro-Rate Portion shall be due and payable at the end
of every three (3) months during such Euro-Rate Interest Period and on the last
day of such Euro-Rate Interest Period, (B) at the maturity, whether by
acceleration or otherwise, of the Revolving Credit Notes and (C) thereafter on

hereof, the Borrower shall have the option of electing, from time to time, one
or more of the Interest Rate Options set forth below to be applied to the
Revolving Credit Loans.

                                    (i)     Base Rate Option. Interest under 
this Interest Rate Option shall accrue, for the Base Rate Portion of the
Revolving Credit Loans outstanding, at a rate per annum equal to the Base Rate.
The Base Rate shall be adjusted automatically from time to time upon each change
in the Prime Rate or the Federal Funds Effective Rate, as the case may be, and
in accordance with the provisions of Section 2.08(c).

                                    (ii)    Euro-Rate Option. Interest under

established pursuant to the preceding sentence of this Section 2.08(b)(ii) for
each Euro-Rate Portion shall be adjusted from time to time in accordance with
the provisions of Section 2.08(c).

subsequent month.

                                    Elections by the Borrower of the Euro-Rate 
Option shall be subject to the following limitations:

                                    (i)     The Euro-Rate Portion for each 
Euro-Rate Interest Period shall be in an aggregate principal amount of
$5,000,000 or more; provided, however, that each increment in excess of
$5,000,000 shall be $1,000,000 or an integral multiple thereof;

                                    (ii)    No Euro-Rate Interest Period may be
elected at any time that a Default or an Event of Default shall have occurred
and be continuing;

                                    (iii)   No Euro-Rate Interest Period may be
elected which would end later than the relevant Expiration Date;

                                    (iv)    No Euro-Rate Interest Period may be
elected with regard to amounts outstanding which would be in excess of the
Revolving Credit Commitment or the Borrowing Base, whichever is less; and

                                    (v)     At no time may there be more than 
four (4) separate EuroRate Interest Periods in effect.

                           (e)      Election' Renewal or Conversion of Interest
Rate Options. Elections or renewals of, or conversions to, the Base Rate Option
shall continue in effect until converted or renewed as hereinafter provided.
Elections or renewals of, or conversions to, the Euro-Rate Option shall expire
as to each Euro-Rate Portion at the expiration of the applicable Euro-Rate
Interest Period. At any time with respect to the Base Rate Portion or at the
expiration of the applicable Euro-Rate Interest Period with respect to any
Euro-Rate Portion, the Borrower may cause (subject to Subsection 2.08(d)) all or
any part of the principal amount of such portion to be converted to, or to be
renewed under, the Euro-Rate Option by notice to the Agent as hereinafter
provided. Such notice (i) shall be irrevocable, (ii) shall be given not later
than noon (Pittsburgh, Pennsylvania time) in the case of a conversion to or
renewal of, either in whole or in part, the Euro-Rate Option, not less than
three (3) Business Days prior to the proposed effective date for such conversion
or renewal, and (iii) shall set forth:

                                    (A)     the effective date of such 
         conversion or renewal, which shall be a Business Day;

                                    (B)     the new Euro-Rate Interest Period(s)
         selected; and

                                    (C)     with respect to each such Euro-Rate
         Interest Period, the aggregate principal amount of the corresponding 
         Euro-Rate Portion.

At the expiration of each Euro-Rate Interest Period, any part (including the
whole) of the principal amount of the corresponding Euro-Rate Portion as to
which no notice of conversion or renewal has been received shall automatically
be converted to the Base Rate Option. The Agent shall promptly notify the
Borrower and the Lenders of any such automatic conversion.



                                     - 30 -
<PAGE>   38

                           (f)      Notification of Election of an Interest 
Rate Option. The Borrower, by an Authorized Officer, shall notify the Agent of
each election of an Interest Rate Option, each conversion from one Interest Rate
Option to another, the amount of the Revolving Credit Loans then outstanding to
be allocated to each Interest Rate Option and, where relevant, the Euro-Rate
Interest Periods as provided for in this Agreement. Any such communication may
be oral or written and if oral it shall be followed promptly by written
confirmation of such Interest Rate Option election executed by an Authorized
Officer of the Borrower.

                           (g)      Calculation of Interest. Interest on the 
Base Rate Portion shall be calculated on the basis of a 365 or 366 day year, as
the case may be, and the actual days elapsed. Interest on each Euro-Rate Portion
shall be calculated on the basis of a 360-day year and the actual days elapsed.
The calculation of the amount of interest due and owing to the Lenders shall be
evidenced by posting the amount of interest due under the Revolving Credit Notes
to the Loan Account established by the Agent pursuant to Section 2.14.

                           (h)      Lawful Interest Rates Intended. In no event
whatsoever shall the interest rates charged hereunder exceed the highest rate
permissible under any law which a court of competent jurisdiction shall, in a
final determination, deem applicable hereto. In the event that such a court
determines that any Lender has received interest hereunder in excess of the
highest applicable rate, such Lender shall promptly refund such excess to the
Borrower, or at such Lender's option, apply such excess in reduction of the
principal balance of the Lender Obligations owing to the affected Lender.

                  2.09.    Prepayments: Allocation of Repayments.

                           (a)      Prepayments of Base Rate Portion. The 
Borrower, upon oral or written notice to the Agent by an Authorized Officer of
Borrower given not later than 12:00 noon (Pittsburgh, Pennsylvania time) on the
proposed date for prepayment, may prepay without penalty or premium any or all
of the Base Rate Portion. Any oral notice of election hereunder shall be
followed immediately by written confirmation of such prepayment election
executed by an Authorized Officer of Borrower

                           (b)      Prepayments of Euro-Rate Portions. Except 
as otherwise provided in Section 2.10(c), the Borrower, upon oral or written
notice to the Agent by an Authorized Officer of Borrower given at least three
(3) Business Days prior to the proposed date for repayment, may prepay, all or
any part of such Euro-Rate Portion. If such Euro-Rate Portion is prepaid on the
last day of the Euro-Rate Interest Period applicable thereto, such prepayment
shall be without premium or penalty. If the Borrower prepays a Euro-Rate Portion
other than on the last day of the Euro-Rate Interest Period applicable thereto,
the Borrower agrees to pay, in addition to the other amounts set forth in this
Section 2.09(b), such additional amounts as may be necessary to compensate each
Lender for any loss (including loss of profit on a pre-tax basis) and any direct
or indirect costs, including the costs of reemployment of funds prepaid at rates
lower than the cost to such Lender of such funds. Such losses and costs shall be
specified in writing to the Borrower by the affected Lenders (and such
specifications shall set forth in reasonable detail the calculation of such
losses and costs) and such 



                                     - 31 -
<PAGE>   39

specifications shall, absent manifest error, be binding and conclusive on the
Borrower. Such prepayment shall include the then outstanding principal amount of
the Euro-Rate Portion being prepaid together with accrued interest, fees and
other amounts then due and payable on the amount prepaid, to the day of such
prepayment. Except as provided in this Section 2.09(b), there shall be no
voluntary prepayment of any Euro-Rate Portion.

                           (c)      Allocation of Repayments of Principal. Any 
voluntary prepayment pursuant to this Section 2.09 hereof shall be applied first
to the repayment of any Euro-Rate Portion of the Revolving Credit Loans for
which its associated Euro-Rate Interest Period expires on the date of such
payment, second, to the reduction of the Base Rate Portion of the Revolving
Credit Loans, and third, to the reduction of such Euro-Rate Portions of the
Revolving Credit Loans as directed by the Borrower, and if the Borrower fails to
give such directions, or if a Default or Event of Default has occurred and is
continuing, to the reduction of such Euro-Rate Portions of the Revolving Credit
Loans as the Agent may select in its sole and absolute discretion. Any reduction
in any Euro-Rate Portion on a date other than the date on which its associated
Euro-Rate Interest Period expires may result in a funding loss for which the
Borrower will owe the Lenders an indemnity payment pursuant to Section 2.10
hereof.

                  2.10.    Yield Protection.

                           (a)      If any change subsequent to the Closing 
Date in any Law or in the interpretation or application thereof by any Official
Body or in the compliance with any guideline or request from any Official Body,
shall make it unlawful for any Lender to maintain or give effect to its
obligations as contemplated under the Revolving Credit Commitment or for PNC
Bank to maintain or give effect to its obligation to make Swingline Loans, such
Lender shall notify the Borrower and the Agent in writing of its determination
of such unlawfulness and an explanation thereof. Thereafter, such Lender's
obligation to make available any further Revolving Credit Loans hereunder, and
PNC Bank's obligation to make available any further Swingline Loans hereunder
shall forthwith be cancelled and the Borrower, within thirty (30) days, or
within such longer period as may be allowed by Law, if any, shall repay to such
Lender so affected its pro rata share of the outstanding principal amount of all
Revolving Credit Loans and/or Swingline Loans, together with interest thereon to
the date of repayment and fees, if any, due as of the date of termination;
provided, however, that the affected Lender's obligations which are lawful, if
severable from those which are unlawful, shall continue, and with respect to
those obligations, this Agreement shall not terminate.

                           (b)      If any Law issued after the Closing Date
(including, without limitation, Regulation D of the Federal Reserve Board), or
if any change on or after the Closing Date in any Law (including, without
limitation, Regulation D) or in the interpretation thereof by any Official Body
charged with the administration thereof, shall

                                    (i)     subject any Lender to any tax, levy,
impost, charge, fee, duty, deduction or withholding or any kind hereunder (other
than any tax imposed or based upon the income of such Lender and payable to any
governmental or taxing authority in the United States of America, any state or
any municipality thereof); or


                                     - 32 -
<PAGE>   40

                                    (ii)    change the basis of taxation of any
Lender with respect to payments of principal or interest or other amounts due
hereunder (other than any change which affects, and only to the extent that it
affects, the taxation by the United States, any state or any municipality
thereof based upon the income of such Lender); or

                                    (iii)   impose, modify or deem applicable 
any reserve, special deposit or similar requirements against assets held by any
Lender (other than such requirements which result solely from a change in the
credit quality of the Borrower or which are included in the determination of the
applicable rate of interest hereunder); or

                                    (iv)    impose upon any Lender any other
obligation or condition with respect to this Agreement,

and the result of any of the foregoing is to increase the cost to any Lender, to
decrease the yield to any Lender with respect to the Revolving Credit Loans, the
Swingline Loans or any Letters of Credit, to reduce the income receivable by any
Lender or to impose any expenses upon any Lender with respect to the Revolving
Credit Loans, the Swingline Loans or any Letters of Credit by an amount which
any Lender reasonably deems material, then and in any such case:

                                            (A)      the Lender so affected 
shall promptly notify the Borrower and the Agent of the happening of such event;

                                            (B)      the Borrower shall pay to 
the affected Lender, within five (5) Business Days of written demand such amount
as will compensate such Lender for such additional cost or reduced amount,
calculated from the date of the notification by such Lender; and

                                            (C)      the Borrower may pay to 
such affected Lender the affected Revolving Credit Loan or Swingline Loan in
full without the payment of any additional amount other than on account of such
Lender's out-of-pocket losses (including funding losses, if any, as provided in
paragraph (c) below) not otherwise provided for in subparagraph (B) immediately
above.

The Lender so affected shall present to the Borrower and the Agent a certificate
setting forth such increased cost or reduced amount. Such certificate shall set
forth in reasonable detail the calculation of the amount due and such Lender's
reasons for invoking the provisions of this Section 2.10(b). Such certificate
shall be conclusive evidence of the amount due thereunder except in the case of
manifest error in computation.

                           (c)      The Borrower agrees to indemnify each 
Lender, on demand, against any loss or expense (including loss of profit) which
such Lender may sustain or incur in liquidating or employing deposits from third
parties acquired to effect, fund or maintain



                                     - 33 -
<PAGE>   41

such Euro-Rate Portions or any part thereof as a consequence of (i) the failure
of the Borrower to make a payment on the due date thereof, (ii) the failure of
the Borrower to borrow under, convert to or renew under the Euro-Rate Option on
the proposed effective date of such borrowing, conversion or renewal, or (iii)
the payment, prepayment or conversion by the Borrower of any Euro-Rate Portions
for any reason on a day other than the last day of the applicable Euro-Rate
Interest Period. Any Lender's determination of an amount payable under this
paragraph (c) shall be conclusive absent manifest error.

                           (d)      The foregoing notwithstanding, if the 
affected Lender can mitigate or eliminate such increased cost or reduced yield
by transferring the Loans to another existing lending office of such Lender,
such Lender agrees to so transfer the Loans; provided, such transfer would not
subject such Lender to any unreimbursed cost or expense and would not otherwise
be disadvantageous to such Lender.

                  2.11.    Special Provisions Relating to the Euro-Rate Option.

                           (a)      Euro-Rate Unascertainable. In the event that
on any date on which a Euro-Rate Option would otherwise be set, the Agent shall
have determined (which determination shall be final and conclusive) that, by
reason of circumstances affecting the London interbank market, adequate,
reasonable means do not exist for ascertaining the EuroRate, the Agent shall
give prompt notice of such determination to the Borrower and the Lenders. Until
the Agent notifies the Borrower and the Lenders that the circumstances giving
rise to such determination no longer exist (which notice shall be given promptly
following receipt of knowledge thereof by the Agent), the right of the Borrower
to borrow under, convert to or renew the Euro-Rate Option shall be suspended.
Any notice of borrowing under, conversion to or renewal of the Euro-Rate Option
which was to become effective during the period of such suspension shall be
treated as a request to borrow under, convert to or renew the Base Rate Option
with respect to the principal amount therein specified.

                           (b)      Inability to Offer Euro-Rate. In the event 
that any Lender shall determine, in its sole discretion, that it is unable to
obtain deposits in the London interbank market in sufficient amounts and with
maturities related to such Euro-Rate Portions which would enable such Lender to
fund such Euro-Rate Portions, then such Lender shall notify the Borrower and the
Agent that the right of the Borrower to borrow under, convert to or renew the
Euro-Rate Option, shall be suspended with respect to such Lender. Such notice
shall set forth in reasonable detail such Lender's reasons for invoking the
provisions of this Section 2.11(b). Following notification of the suspension of
the Euro-Rate Option with respect to such Lender, the Borrower agrees to
negotiate with such Lender for a modified or alternative fixed rate of interest,
which will allow such Lender to realize its anticipated and bargained-for yield.
In the event that the Borrower and such Lender cannot agree on a modified or
alternative fixed rate of interest, any notice of borrowing under, conversion to
or renewal of the Euro-Rate Option which was to become effective during the
period of suspension shall be treated as a request to borrow under, convert to
or renew the Base Rate Option with respect to the principal amount specified
therein attributable to such Lender.



                                     - 34 -
<PAGE>   42

                           (c)      Illegality. If any Lender shall determine 
in good faith (which determination shall be final and conclusive) that
compliance with any Law (whether or not having the force of law) or the
interpretation or application thereof by any Official Body, has made it unlawful
or impractical for such Lender to make or maintain the Revolving Credit Loans
under the Euro-Rate Option, such Lender shall give notice of such determination
to the Borrower and the Agent, which notice shall set forth in reasonable detail
such Lender's reasons for invoking the provisions of this Section 2.11(c).
Notwithstanding any provision of this Agreement to the contrary, unless and
until such Lender shall have given notice to the Borrower and the Agent that the
circumstances giving rise to such determination no longer apply (which notice
shall be given promptly following receipt of knowledge thereof by such Lender):

                           (i)      with respect to any Euro-Rate Interest 
Periods thereafter commencing, interest in an amount equal to such Lender's
Ratable Share of the corresponding Euro-Rate Portion shall be computed and
payable under the Base Rate Option; and

                           (ii)     on such date, if any, as shall be required 
by law, an amount equal to such Lender's Ratable Share of any Euro-Rate Portion,
as the case may be, then outstanding shall be automatically converted to the
Base Rate Option and the Borrower shall pay to such Lender the accrued and
unpaid interest on such amounts to (but not including) such conversion date.

The Borrower shall pay any such Lender any additional amounts reasonably
necessary to compensate such Lender for any costs incurred by such Lender as a
result of any conversion pursuant to clause (ii) above which occurs on a day
other than the last day of the relevant Euro-Rate Interest Period, including,
but not limited to, any interest or fees payable by such Lender to lenders of
funds obtained by them to loan or maintain the lending of the Revolving Credit
Loans so converted. Such Lender shall furnish to the Borrower and the Agent a
certificate as to the amount necessary to compensate it for such costs, which
certificate shall set forth in reasonable detail the calculation of the amount
due. Such certificate shall constitute conclusive evidence of the amount due
thereunder absent any manifest error in computation. The Borrower shall pay such
amount to such Lender, as additional consideration hereunder, within ten (10)
days of the Borrower's receipt of such certificate.

                           (d)      The foregoing notwithstanding, if the 
affected Lender can continue to offer the Euro-Rate Option to the Borrower by
transferring the Revolving Credit Loans to another existing lending office of
such Lender, such Lender agrees to so transfer the Revolving Credit Loans;
provided, such transfer would not subject such Lender to any unreimbursed cost
or expense and would not otherwise be disadvantageous to such Lender.

                  2.12. Capital Adequacy. If after the Closing Date (i) any
adoption of or any change in or in the interpretation by an Official Body of any
Law or (ii) compliance with any Law, guideline or request of any Official Body
exercising control over banks or financial institutions generally or any court
(whether or not having the force of law), affects or would affect the amount of
capital required or expected to be maintained by any Lender or any corporation
controlling such Lender other than those resulting solely from a change in the



                                     - 35 -
<PAGE>   43

credit quality of the Borrower (a "CAPITAL ADEQUACY EVENT"), and the result of
such Capital Adequacy Event is to reduce the rate of return on capital of such
Lender or any corporation controlling such Lender as a consequence thereof to a
level below that which such Lender could have achieved but for such Capital
Adequacy Event, taking into consideration such Lender's policies with respect to
capital adequacy, by an amount which such Lender deems to be material, such
Lender shall promptly deliver to the Borrower and the Agent a statement of the
amount necessary to compensate such Lender for the reduction in the rate of
return on its capital attributable to the commitments under this Agreement or
any of the Loan Documents (the "CAPITAL COMPENSATION AMOUNT"). Each Lender shall
determine the Capital Compensation Amount in good faith, using reasonable
attribution and averaging methods. Each Lender shall, from time to time, furnish
to the Borrower and the Agent a certificate setting forth the amount so
determined and the calculations of such amount. Such certificate shall
constitute conclusive evidence of the amount due thereunder absent any manifest
error in computation. Such amount shall be due and payable by the Borrower to
such Lender ten (10) days after such notice is given. As soon as practicable
after any Capital Adequacy Event, such Lender shall submit to the Borrower and
the Agent estimates of the Capital Compensation Amounts that would be payable as
a function of such Lender's Revolving Credit Commitment hereunder.

                  2.13.    Swingline Loans.

                           (a)      Swingline Option. Subject to the provisions
of this Section 2.13, PNC Bank agrees that the Borrower may request that
Swingline Loans, in an aggregate amount at any one time outstanding not to
exceed the lesser of (i) $10,000,000 or (ii) an amount which, when added to the
aggregate principal amount of (A) all other Loans then outstanding, (B) the
aggregate Stated Amount of outstanding Letters of Credit issued pursuant to
Section 2.17 and (C) the aggregate amount of Unreimbursed L/C Draws does not
exceed $125,000,000. PNC Bank shall have no obligation to make Swingline Loans
hereunder on or after the Expiration Date.

                           (b)      Limitations on and Evidence of Swingline 
Loans. Each Swingline Loan or repayment of a Swingline Loan must be in the
minimum principal amount of $1,000,000 or, if in excess of $1,000,000, in
integral multiples of $500,000. Swingline Loans shall be repaid on the date
agreed upon by the Borrower and PNC Bank, not more than five (5) days after the
making of the Swingline Loan and not after the Expiration Date. The obligation
of the Borrower to repay, prior to the Expiration Date, the aggregate unpaid
principal amount of such Swingline Loans advanced by PNC Bank shall be evidenced
by the Swingline Note substantially in the form of Exhibit "A-3" hereto. The
principal amount actually due and owing PNC Bank shall be the aggregate unpaid
principal amount of all disbursements of Swingline Loans made by PNC Bank, all
as shown on such PNC Bank Loan Account established pursuant to Section 2.14.

                           (c)      Swingline Loan Procedure. The Borrower may 
from time to time from the Closing Date to the Business Day prior to the
Expiration Date request a Swingline Loan. Such request shall be made not later
than noon (Pittsburgh, Pennsylvania time) on the date of the proposed Swingline
Loan. Such request may be made to the Agent orally or in 



                                     - 36 -
<PAGE>   44

writing and if orally confirmed in writing. The Agent shall promptly notify PNC
Bank of such request. PNC Bank shall make the Swingline Loan available to the
Borrower not later than 3:00 P.M. (Pittsburgh, Pennsylvania time) on the same
Business Day such Swingline Loan is requested.

                           (d)      Swingline Loan Interest. Interest on the 
Swingline Loans shall accrue at a rate per annum as offered by PNC Bank and
accepted by the Borrower. After the occurrence of an Event of Default and during
the continuation thereof, the Swingline Loans shall bear interest at a rate per
annum which shall be two hundred (200) basis points (2%) above the Base Rate
otherwise in effect during such period.

                           (e)      Risk Participation. Upon the disbursement 
of each Swingline Loan and without any further action by or on behalf of such
Lender, each Lender hereby agrees to purchase, upon the occurrence of an Event
of Default, an undivided, full risk, nonrecourse participation in such Swingline
Loan, in an amount equal to (i) such Lender's Ratable Share (ii) multiplied by
the outstanding principal amount of such Swingline Loan on the date of the Event
of Default; provided, however, no Lender shall participate in any Swingline Loan
made after a notice of an Event of Default has been delivered pursuant to this
Agreement. If and to the extent PNC Bank receives payment of principal or
interest on a participated Swingline Loan, PNC Bank shall deliver to each Lender
such Lender's Ratable Share of such payment.

                  2.14 Loan Account. The Agent shall open and maintain on its
books a Loan Account in the name of the Borrower, with respect to (i) Revolving
Credit Loans and Swingline Loans made, repayments and prepayments of the
principal thereof, and the computation and payment of interest thereon, (ii)
Letters of Credit issued, or participated in, as the case may be, and draws and
reimbursements thereon or thereof, and (iii) the computation and payment of the
Fees due hereunder to the Lenders, the L/C Issuer and the Agent, and the
computation of other amounts due and sums paid to the Agent hereunder. Upon the
request of the Borrower to the Agent, the Agent shall promptly furnish to the
Borrower a statement of the Loan Account. The failure to record any such amount
shall not limit or otherwise affect the obligations of the Borrower hereunder or
under the Notes to repay all amounts owed hereunder and thereunder together with
all interest accrued thereon and all other fees and charges provided herein. The
Loan Account shall be conclusive evidence as to the amount at any time due to
the Lenders, the L/C Issuer and the Agent from the Borrower except in the case
of manifest error.

                  2.15. All Advances to Constitute One Loan. Notwithstanding the
limitations set forth herein, all Revolving Credit Loans, the Swingline Loans
and all other Lender Obligations shall constitute one loan and all Indebtedness
and obligations of the Borrower to the Lenders under this Agreement and all
other Loan Documents shall constitute a general obligation of the Borrower. The
parties hereto agree that all of the rights of the Agent, the L/C Issuer, the
Lenders and the Borrower set forth in this Agreement and the other Loan
Documents shall apply to any amendment or modification of or supplement to this
Agreement and the other Loan Documents.



                                     - 37 -
<PAGE>   45

                  2.16. Use of Proceeds. The proceeds of the Revolving Credit
Loans and the Swingline Loans shall be used exclusively (i) to pay interest,
Fees and other costs, and expenses hereunder and under the other Loan Documents,
(ii) to repay any Unreimbursed L/C Draw, (iii) to repay in full any amounts
outstanding under the Existing Credit Agreement and (iv) to fund capital
expenditures, working capital, acquisitions and general corporate purposes of
the Borrower and its Subsidiaries. No proceeds of any Loan may be used for any
purpose which contravenes applicable law or any provision of any Loan Document.

                  2.17.    Letter of Credit Subfacility.

                           (a)      At the request of the Borrower, the L/C 
Issuer will issue for the account of the Borrower, on the terms and conditions
hereinafter set forth (including without limitation Article V hereof), one or
more Letters of Credit; provided, however, no Letter of Credit shall have an
expiry date later than the earlier of twenty-four (24) months from the date of
issuance or fifteen (15) days prior to the Long-Term Expiration Date; and
provided, further, however, that in no event shall (i) the Stated Amount of the
Letters of Credit issued pursuant to this Section 2.17 exceed, at any one time,
$25,000,000, or (ii) the sum of aggregate outstanding principal balance of the
Long-Term Revolving Credit Loans, the aggregate unpaid balance of outstanding
Swingline Loans, the aggregate unpaid balance of any Unreimbursed L/C Draws and
the aggregate Stated Amount of the Letters of Credit issued by the L/C Issuer
under this Section 2.17 exceed, at any one time, the aggregate Long-Term
Revolving Credit Commitments or the Borrowing Base, whichever is less.

                           (b)      (i)    The Borrower shall pay (A) to the 
L/C Issuer for its own account a fronting fee equal to 1/8 of 1% per annum (the
"L/C FRONTING FEE") on the aggregate daily (computed at the opening of business
and on the basis of a year of 365 or 366 days, as the case may be, and actual
days elapsed) Stated Amount of the outstanding Letters of Credit for the period
in question, and (B) to the Agent for the ratable account of the Lenders a fee
(the "LETTER OF CREDIT FEE") equal to the Applicable Letter of Credit Fee per
annum, as determined below, on the aggregate daily (computed at the opening of
business and on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed) Stated Amount of the outstanding Letters of Credit for the
period in question. The Letter of Credit Fee and the L/C Fronting Fee shall be
payable (A) quarterly in arrears on the last Business Day of each Fiscal Quarter
occurring during the term of this Agreement, (B) on the Long-Term Expiration
Date or (C) upon acceleration of the Notes. Any issuance of an amendment to
extend the stated expiration date of a Letter of Credit or an amendment to
increase the Stated Amount of a Letter of Credit shall be treated as an issuance
of a new Letter of Credit for purposes of calculation of the Letter of Credit
Fee and the L/C Fronting Fee due and payable hereunder. After the occurrence of
an Event of Default and during the continuation thereof, the rate at which the
Letter of Credit Fee is calculated shall be increased by two hundred (200) basis
points (2%) above the pre-default rate.

                                    (ii)   The Borrower shall also pay to the 
L/C Issuer for the L/C Issuer's own account the L/C Issuer's customary
documentation fees payable with respect to the Letters of Credit as the L/C
Issuer may generally charge from time to time. Without limitation, the foregoing
shall include all charges and expenses paid or incurred by the L/C 



                                     - 38 -

Issuer in connection with any Letter of Credit, including without limitation:
(A) correspondents' charges, if any, (B) any and all reasonable out-of-pocket
expenses and charges of the L/C Issuer in connection with the performance,
administration, interpretation, collection and enforcement of this Agreement and
any Letter of Credit, including all reasonable legal fees and expenses, and (C)
any and all applicable reserve or similar requirements and any and all premiums,
assessments, or levies imposed upon the L/C Issuer by any Official Body.

                                    (iii)  If by reason of (A) any change in any
Law or any change in the interpretation or application by any judicial or
regulatory authority of any Law or (ii) compliance by the L/C Issuer with any
direction, request or requirement (whether or not having the force of law) of
any Official Body:

                                            (A)      the L/C issuer shall be 
subject to any tax, levy, charge or withholding of any nature or to any
variation thereof or to any penalty with respect to the maintenance or
fulfillment of its obligations under this Section 2.17, whether directly or by
such being imposed on or suffered by the L/C Issuer;

                                            (B)      any reserve, deposit or 
similar requirement is or shall be applicable, imposed or modified in respect of
the Letters of Credit; or

                                            (C)      there shall be imposed on 
the L/C Issuer any other condition regarding this Section 2.17 or the Letters of
Credit;

and if the result of any of the foregoing is to directly or indirectly increase
the cost to the L/C Issuer of issuing or maintaining any Letter of Credit, or to
reduce the amount receivable in respect thereof by, the L/C Issuer, then and in
any such case the L/C Issuer may, at any time after the additional cost is
incurred or the amount receivable is reduced, notify the Borrower and the Agent,
and the Borrower shall pay on demand such amounts as the L/C Issuer may specify
to be necessary to compensate the L/C Issuer for such additional cost or reduced
receipt, together with interest on such amount from the date of the notice of
such event which results in such increased cost or reduction in amount
receivable until payment in full thereof at a rate equal at all times to the
Base Rate. The determination by the L/C Issuer of any amount due pursuant to
this Subsection 2.17(b)(ii) as set forth in a certificate setting forth the
calculation thereof, shall, in the absence of manifest error, be final and
conclusive and binding on all of the parties hereto.

For purposes of this Agreement, the term "APPLICABLE LETTER OF CREDIT FEE" shall
mean the rate per annum set forth in the chart below which corresponds to the
range of ratios in which the Borrower's Consolidated Total Indebtedness to
Consolidated EBITDA Ratio as at the end of the preceding Fiscal Quarter falls:

All adjustments shall be determined as of the date the Borrower's quarterly
financial statements and Compliance Certificate are required to be delivered
pursuant to items (i) and (iii) of Section 6.02. The foregoing notwithstanding,
the Applicable Letter of Credit Fee from the Closing Date to and including the
June 1998 Delivery Date shall be .50%.

                           (c)      Immediately upon the issuance of each 
Letter of Credit and each increase in the Stated Amount thereof, each Lender
hereby agrees to irrevocably purchase and shall be deemed to have irrevocably
purchased from the L/C Issuer an undivided, full risk, non-recourse
participation in such Letter of Credit and drawings thereunder in an amount
equal to such Lender's Ratable Share of the maximum amount which is or at any
time may become available to be drawn thereunder. In the event that the L/C
Issuer is required for any reason to refund or repay to the Borrower, any
guarantor or any other Person all or any portion of any amount remitted to the
L/C Issuer pursuant to this Agreement, the Lenders shall promptly remit to the
L/C Issuer, upon three (3) Business Days' demand therefor, their respective
Ratable Shares of the amount which is so refunded or repaid.

                           (d)      In the event any restrictions are imposed 
upon the L/C Issuer or any of the Lenders by any Law of any Official Body having
jurisdiction over the banking activities of the L/C Issuer or any Lender which
would prevent the L/C Issuer from issuing the Letters of Credit or amending the
Letters of Credit or would prevent any Lender from honoring its obligations
under this Section 2.17, the commitment of the L/C Issuer to issue the Letters
of Credit or enter into any amendment with respect thereto shall be immediately
suspended. If any Lender believes any such restriction would prevent such Lender
from honoring its obligations under this Section 2.17, it shall promptly notify
the Agent. The Agent shall promptly notify the Borrower, the L/C Issuer and the
other Lenders of the existence and nature of (i) any restriction which would
cause the suspension of the commitment of the L/C Issuer to issue the Letters of
Credit or to enter into amendments with respect thereto and (ii) any restriction
which would prevent any Lender from honoring its obligations under this Section
2.17. The Borrower will thereupon undertake reasonable efforts to obtain the
cancellation of all outstanding Letters of Credit; provided, however, that the
refusal of any beneficiary of a Letter of Credit to surrender such Letter of
Credit will not be an Event of Default hereunder, provided that the Borrower
shall undertake good faith efforts to obtain substitute letters of credit for
the then existing and outstanding Letters of Credit. Nothing contained in this
Section 2.17 shall be deemed a termination of the Revolving Credit Commitments
and, in the event of a suspension of the commitment of the L/C Issuer to issue
Letters of Credit as set forth above, the Borrower may continue to borrow under
the Revolving Credit Commitments provided the requirements of Section 5.02 are
complied with.

                           (e)      When the Borrower desires the issuance of 
a Letter of Credit, the Borrower shall deliver a duly completed Application and
Agreement for Letter of Credit to the L/C Issuer, with a copy to the Agent, no
later than 11:00 A.M. (Pittsburgh, Pennsylvania time) at least three (3)
Business Days, or such shorter period as may be agreed to by the L/C Issuer, in
advance of the proposed date of issuance. Upon satisfaction of the conditions
set forth in Section 5.01 and, if applicable, Section 5.02, the L/C Issuer shall
be obligated to issue the Letter of Credit and shall notify the Agent and each
Lender of such issuance. In determining whether to pay under a Letter of Credit,
the L/C Issuer shall be responsible only to determine that the documents and
certificates required to be delivered under the Letter of Credit have been
delivered and that they comply on their face with the requirements of the Letter
of Credit.

                           (f)      In the event of any request for drawing 
under a Letter of Credit by the beneficiary thereof, the L/C Issuer shall
immediately notify the Borrower and the Agent, and the Borrower shall reimburse,
or cause the reimbursement of, the L/C Issuer on demand as set forth in the
applicable Application and Agreement for Letter of Credit in an amount in same
day funds equal to the amount of such drawing; provided, however, that anything
contained in this Agreement to the contrary notwithstanding, unless the Borrower
shall have notified the Agent and the L/C Issuer prior to such time that the
Borrower intends to reimburse the L/C Issuer for all or a portion of the amount
of such drawing with funds other than the proceeds of Revolving Credit Loans,
the Borrower shall be deemed to have given a Loan Request to the Agent
requesting the Lenders to make Revolving Credit Loans on the first Business Day
immediately following the date on which such drawing is honored in an aggregate
amount equal to the excess of the amount of such drawing over the amount
received by the L/C Issuer from such other funds in reimbursement thereof (the
"UNREIMBURSED L/C DRAW"), plus accrued interest on such amount at the rate set
forth in Subsection 2.08. Any such Revolving Credit Loan shall be deemed
advanced to the Borrower. If the Borrower shall be deemed to have given a Loan
Request, then, subject to satisfaction or waiver of the conditions specified in
Section 5.02, the Lenders shall, all as set forth in Section 2.17(g) hereof, on
the first Business Day immediately following the date of such drawing, make
Revolving Credit Loans in the aggregate amount of the Unreimbursed L/C Draw plus
accrued interest on such amount at the applicable rate set forth in Section
2.08. The proceeds of any such Revolving Credit Loans shall be applied directly
by the Agent upon receipt from the Lenders to reimburse the L/C Issuer for the
Unreimbursed L/C Draw plus accrued interest on such amount. The foregoing shall
not limit or impair the obligation of the Borrower to reimburse the L/C Issuer
on demand.

                           (g)      In the event that the Borrower shall fail to
reimburse the L/C Issuer on demand as provided in the applicable Application and
Agreement for Letter of Credit and Section 2.17(f) above in an amount equal to
the amount of any drawing honored by the L/C Issuer under a Letter of Credit
plus accrued interest, the L/C Issuer shall promptly notify the Agent and each
Lender of the Unreimbursed L/C Draw plus accrued interest on such amount of such
drawing and of such Lender's respective participation therein. Each Lender shall
make available to the L/C Issuer an amount equal to its respective participation
in same day funds, at the office of the L/C Issuer specified in such notice, not
later than 12:00 Noon 


                                     - 41 -
<PAGE>   49

(Pittsburgh, Pennsylvania time) on the Business Day after the date specified in
such notice by the L/C Issuer. In the event that any Lender fails to make
available to the L/C Issuer the amount of such Lender's participation in such
Letter of Credit as provided in this Section 2.17(g), the L/C Issuer shall be
entitled to recover such amount on demand from such Lender together with
interest at the Federal Funds Effective Rate for three (3) Business Days and
thereafter at the Base Rate. Nothing in this Section 2.17(g) shall be deemed to
prejudice the right of any Lender to recover its Ratable Share of the
Unreimbursed L/C Draw from the L/C Issuer pursuant to this Section 2.17(g) in
the event that it is determined by a court of competent jurisdiction that
payment with respect to a Letter of Credit by the L/C Issuer constituted gross
negligence or willful misconduct on the part of the L/C Issuer. The L/C Issuer
shall distribute to each Lender which has paid all amounts payable by it under
this Section 2.17(g) with respect to a Letter of Credit such other Lender's
Ratable Share of all payments received by the L/C Issuer from the Borrower in
reimbursement of drawing honored by the L/C Issuer under the Letter of Credit
when such payments are received.

                           (h)      The obligations of the Borrower under this 
Agreement to reimburse the L/C Issuer for all drawings upon the Letters of
Credit shall be absolute, unconditional and irrevocable, and shall not be
subject to any right of set-off or counterclaim and shall be paid or performed
strictly in accordance with the terms of this Agreement, under all circumstances
whatsoever, including the following circumstances:

                                    (i)     any lack of validity or 
enforceability of this Agreement, any Letter of Credit or any of the Loan
Documents;

                                    (ii)    any amendment or waiver of any 
provision of all or any of the Loan Documents;

                                    (iii)   the existence of any claim, set-off,
defense or other rights which the Borrower may have at any time against any
beneficiary or any transferee of any Letter of Credit (or any Persons for whom
any such beneficiary or any such transferee may be acting), the L/C Issuer, the
Agent or any Lender (other than the defense of payment to the L/C Issuer in
accordance with the terms of this Agreement) or any other Person, whether in
connection with this Agreement, the Loan Documents or any transaction
contemplated hereby or thereby or any unrelated transaction;

                                    (iv)    any draft, demand, certificate,
statement or document presented under any Letter of Credit, appearing on its
face to be valid and sufficient, but proving to be forged, fraudulent, invalid
or insufficient in any respect or any statement therein being untrue or
inaccurate in any respect whatsoever;

                                    (v)     payment by the L/C Issuer under any
Letter of Credit against presentation of any document which does not comply with
the terms of the Letter of Credit, provided that such payment shall not have
constituted gross negligence or willful misconduct of the L/C Issuer;



                                     - 42 -
<PAGE>   50

                                    (vi)    any other circumstance or happening
whatsoever, whether or not similar to any of the foregoing, not resulting from
gross negligence or willful misconduct of the L/C Issuer; and

                                    (vii)   the fact that a Default or Event of
Default shall have occurred and be continuing.

                           (i)      This Agreement is intended to supplement 
each Application and Agreement for Letter of Credit executed by the Borrower and
delivered to the L/C Issuer. Whenever possible this Agreement is to be construed
as consistent with each Application and Agreement for Letter of Credit but, to
the extent that the provisions of this Agreement and each Application and
Agreement for Letter of Credit conflict, the terms of this Agreement shall
control.

                           (j)      Outstanding Letters of Credit. As of the 
Closing Date, each of the Letters of Credit issued by the L/C Issuer and
outstanding on such date for the account of the Borrower and identified on
Schedule 2.17(j) shall be deemed to be Letters of Credit issued hereunder and
shall be subject to all of the terms and provisions of this Agreement. The
Borrower is hereby deemed to be the account party with respect to each letter of
credit listed on Schedule 2.17(j) hereunder for all purposes thereunder and
hereunder. Each Lender agrees that its obligations with respect to Letters of
Credit pursuant to this Agreement shall include such outstanding letters of
credit. With respect to each such outstanding letter of credit, for the period
commencing on the Closing Date the Borrower shall pay all fees and commissions
set forth in this Agreement at the times and in the manner herein set forth. The
obligations of the Borrower under each application for letter of credit and
reimbursement agreement (together with any related amendments) executed by the
Borrower with respect to the letters of credit shown on Schedule 2.17(j) are
hereby expressly assumed by the Borrower and each such application for letter of
credit and reimbursement agreement, as amended, is hereby deemed an Application
and Agreement for Letter of Credit. The existing reimbursement agreements shall
be superseded in their entirety by this Agreement which shall apply to existing
letters of credit set forth on Schedule 2.17(j) as well as all Letters of Credit
issued hereunder on and after the date hereof.

                           (k)      Obligations Absolute. Notwithstanding any 
other provision of this Agreement, each Lender hereby agrees that its obligation
to participate in each Letter of Credit issued in accordance herewith and its
obligation to make the payments to be made by it under this Section 2.17 is
absolute, irrevocable and unconditional and shall not be affected by any event,
condition or circumstance whatever. The failure of any Lender to make any such
payment shall not relieve any other Lender of its funding obligation hereunder
on the date due, but no Lender shall be responsible for the failure of any other
Lender to meet its funding obligations hereunder.

                           (l)      In addition to amounts payable as elsewhere
provided in this Section 2.17, the Borrower hereby agrees to protect, indemnify,
pay and save the Agent or the L/C Issuer harmless from and against any and all
claims, demands, liabilities, damages, losses, costs, charges and expenses
(including reasonable attorneys' fees) which the Agent or 



                                     - 43 -
<PAGE>   51

the L/C Issuer may incur or be subject to as a consequence, direct or indirect,
of (i) the issuance of the Letters of Credit or any amendment thereto, other
than as a result of the gross negligence or willful misconduct of the Agent or
the L/C Issuer as determined by a court of competent jurisdiction, (ii) the
failure of the L/C Issuer to honor a draw under any Letter of Credit if the L/C
Issuer in good faith and upon advice of counsel believes that it is prohibited
from making such payment as a result of any requirement of Law or of any
Official Body, or (iii) any material breach by the Borrower of any
representation, warranty, covenant, term or condition in, or the occurrence of
any default under, any document related to the issuance or any amendment of the
Letters of Credit. If any proceeding shall be brought or threatened against the
Agent or the L/C Issuer by reason of or in connection with any event described
in clauses (i) through (iii) above, the Agent shall promptly notify the Borrower
in writing, and the Borrower shall assume the defense thereof, including the
employment of counsel and payment of all costs of litigation. Notwithstanding
the preceding sentence, the Agent and the L/C Issuer shall have the right to
employ their own counsel and to determine its own defense of such action in any
such case, but the fees and expenses of such counsel shall be at the expense of
the Agent or the L/C Issuer, as the case may be, unless (x) the employment of
such counsel shall have been authorized in writing by the Borrower, (y) the
Borrower, after the aforementioned notice of the action, shall not have employed
counsel to have charge of such defense or (z) if the position of the Borrower is
adverse or contrary to the position advocated by the Agent or the L/C Issuer, as
the case may be. In each case described in clauses (x), (y) and (z) immediately
above the reasonable fees and expenses of counsel for the Agent or the L/C
Issuer, as the case may be shall be borne by the Borrower. The Borrower shall
not be liable for any settlement of any such action affected without its
consent.

                           (m)      The L/C Issuer is hereby expressly 
authorized and directed to honor any request for payment which is made under and
in compliance with the terms of any Letter of Credit without regard to, and
without any duty on the L/C Issuer's part to inquire into, the existence of any
disputes or controversies between the Borrower, the beneficiary of any Letter of
Credit or any other Person, or the respective rights, duties or liabilities of
any of them or whether any facts or occurrences represented in any of the
documents presented under any Letter of Credit are true or correct. Furthermore,
the Borrower fully understands and agrees that the L/C Issuer's sole obligation
to the Borrower shall be limited to honoring requests for payment made under and
in compliance with the terms of any Letter of Credit, the Application and
Agreement for Letter of Credit therefor and this Agreement and the L/C Issuer's
obligation remains so limited even if the L/C Issuer may have assisted the
Borrower in the preparation of the wording of any Letter of Credit or any
documents required to be presented thereunder or that the L/C Issuer may
otherwise be aware of the underlying transaction giving rise to any Letter of
Credit and this Agreement.

                           (n)      As between the Borrower and the L/C Issuer,
the Borrower assumes all risks of the acts and omissions of, or misuse of the
Letters of Credit by, the beneficiaries of the Letters of Credit. In furtherance
and not in limitation of the foregoing, the L/C Issuer shall not be responsible:
(i) for the form, validity, sufficiency, accuracy, genuineness or legal effect
of any document submitted by any party in connection with the application for or
the issuance or amendment of the Letters of Credit, even if it should in fact
prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent
or forged; (ii) for 



                                     - 44 -
<PAGE>   52

the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign the Letters of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason; (iii) for failure of a beneficiary of a
Letter of Credit to comply fully with conditions required in order to draw upon
such Letter of Credit; (iv) for errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telecopy,
telex or otherwise, whether or not they be in cipher; (v) for errors in
interpretation of technical terms; (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a draw under
the Letters of Credit or of the proceeds thereof; (vii) for the misapplication
by a beneficiary of any Letter of Credit of the proceeds of any drawing under
such Letter of Credit; (viii) for any consequences arising from causes beyond
the control of the L/C Issuer, including, without limitation, any Law; and (ix)
for any other circumstances whatsoever in making or failing to make payment
under a Letter of Credit; except that the Borrower shall have a claim against
the L/C Issuer, and the L/C Issuer shall be liable to the Borrower, to the
extent, but only to the extent, of any direct, as opposed to consequential,
damages suffered by the Borrower by a court of competent jurisdiction to be the
result of (i) the L/C Issuer's willful misconduct or gross negligence in
determining whether documents presented under a Letter of Credit comply with the
terms of the Letter of Credit, (ii) the L/C Issuer's willful misconduct or gross
negligence in paying a draw under a Letter of Credit to any Person other than
the beneficiary of such Letter of Credit or its lawful successor, representative
or assign (or as otherwise directed in writing by the beneficiary of such Letter
of Credit) or (iii) the L/C Issuer's willful failure to pay under a Letter of
Credit after the presentation to it by the beneficiary of such Letter of Credit
or its lawful successor, representative or assign of a sight draft and
certificate or other documents strictly complying with the terms and conditions
of such Letter of Credit, unless the L/C Issuer in good faith and upon advice of
counsel believes that it is prohibited by law or other legal authority from
making such payment. None of the above shall affect, impair, or prevent the
vesting of any of the L/C Issuer's rights or powers hereunder.

                           (o)      Except for the L/C Issuer's obligations to 
issue Letters of Credit hereunder and its obligations under such Letters of
Credit, the L/C Issuer shall have no liability to the Borrower from a reduction
of the L/C Issuer's credit rating or any deterioration in its financial
condition.

                           (p)      The Borrower shall bear and pay all 
reasonable expenses of every kind (including all reasonable attorneys' fees) of
the enforcement of any of the L/C Issuer's rights under this Agreement or the
Letters of Credit, or of any claim or demand by the L/C Issuer against the
Borrower, or of any actual or attempted sale, exchange, enforcement, collection,
maintenance, retention, insurance, compromise, settlement, release, delivery on
trust receipt, or other security agreement, or delivery of any such security,
and of the receipt of proceeds thereof, and will repay to the L/C Issuer any
such expenses incurred by the L/C Issuer.

                           (q)      In furtherance and extension and not in 
limitation of the specific provisions hereinabove set forth, any action taken or
omitted by the L/C Issuer under or in connection with the Letters of Credit or
the related sight drafts or certificates or documents, if taken or omitted in
good faith, shall not put the L/C Issuer under any resulting liability to the
Borrower.

                           (r)      Whenever appropriate to prevent unjust 
enrichment and to the end that the Borrower shall bear substantially all of the
risks relative to any Letter of Credit and the underlying transactions, the L/C
Issuer shall be subrogated (for purposes of defending against the Borrower's
claims and proceeding against others to the extent of the L/C Issuer's liability
to the Borrower) to the Borrower's rights against any Person who may be liable
to the Borrower on any underlying transaction, to the rights of any holder in
due course or Person with similar status against the Borrower, and to the rights
of the beneficiary or its assignee or person with similar status against the
Borrower.

                           (s)      Except and to the extent inconsistent with 
the specific provisions hereof, this Agreement, each Letter of Credit hereunder
and all transactions in connection therewith shall be interpreted, construed and
enforced according to: (i) the "Uniform Customs and Practice for Documentary
Credits" (1993 Revision), International Chamber of Commerce Publication No. 500
and subsequent revisions thereof which shall supersede inconsistent provisions
of applicable law to the extent not prohibited by applicable law and (ii) the
laws of the Commonwealth of Pennsylvania, including, without limitation, the
Uniform Commercial Code, and excluding conflict of laws rules.

                  2.18. Taxes. Each Lender that is not incorporated under the
laws of the United States of America or a state thereof agrees that it will
deliver to the Borrower and the Agent (i) two duly completed copies of United
States Internal Revenue Service Form 1001 or 4224 or successor applicable form,
as the case may be (assuming that it is entitled to do so), and (ii) two duly
completed copies of Internal Revenue Service Form W-8 or W-9 or successor
applicable form. Each such Lender also agrees to deliver to the Borrower and the
Agent two further copies of the said Form 1001 or 4224 and Form W-8 or W-9, or
successor applicable forms or other manner of certification, as the case may be,
on or before the date that any such form expires or becomes obsolete or
otherwise is required to be resubmitted as a condition to obtaining an exemption
from withholding tax or after the occurrence of any event requiring a change in
the most recent form previously delivered by it to the Borrower and the Agent,
and such extensions or renewals thereof as may reasonably be requested by the
Borrower or the Agent, unless in any such case an event (including, without
limitation, any change in treaty, law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Lender from duly completing
and delivering any such form with respect to it and such Lender so advises the
Borrower and the Agent. Such Lender shall certify (i) in the case of Form 1001
or 4224, that it is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes (assuming
that it is entitled to do so) and (ii) in the case of Form W-8 or W-9, that it
is entitled to an exemption from United States backup withholding tax.

                  2.19. Payments. All payments and prepayments to be made in
respect of principal, interest, Unreimbursed L/C Draws, Fees, or other amounts
due from the Borrower hereunder shall be payable prior to 11:00 A.M.
(Pittsburgh, Pennsylvania time) on the date 



                                     - 46 -
<PAGE>   54

when due without presentment, demand, protest or notice of any kind, all of
which are hereby expressly waived by the Borrower, and without setoff,
counterclaim or other deduction of any nature, and an action therefor shall
immediately accrue. Such payments shall be made to the Agent at the Principal
Office for the ratable account of the Lenders or L/C Issuer, as the case may be,
in Dollars and in immediately available funds, and the Agent shall promptly
distribute such amounts to the Lenders or L/C Issuer, as the case may be, in
immediately available funds in accordance with the terms and provisions of
Section 9.10 of this Agreement. The Agent's, the L/C Issuer's and each Lender's
statement of account, ledger or other relevant record shall, in the absence of
manifest error, be conclusive as the statement of the amount of principal of and
interest on the Revolving Credit Loans, the Swingline Loans, the Unreimbursed
L/C Draws, Fees and other amounts owing under this Agreement and shall be deemed
an "account stated." Notwithstanding anything herein to the contrary, (i) any
administration or underwriting fee paid by the Borrower to the Agent shall be
solely for the account of the Agent, (ii) any L/C Fronting Fees paid by the
Borrower shall be solely for the account of the L/C Issuer and (iii) any
interest paid on any Unreimbursed L/C Draw to the extent a Lender has not been
required to honor or has not honored its funding obligations pursuant to Section
2.17(g) hereof shall be solely for the account of the L/C Issuer.

                  2.20. Substitution of Lender. In the event any Lender (i)
gives notice under Sections 2.10 (Yield Protection), 2.11(b) (Inability to Offer
Euro-Rate), 2.11(c) (Illegality) or 2.12 (Capital Adequacy), (ii) does not fund
Revolving Credit Loans because the making of such Loans would contravene any Law
applicable to such Lender, (iii) does not approve any action as to which consent
of the Required Lenders is requested by the Borrower and obtained hereunder, or
(iv) becomes subject to the control of an Official Body (other than normal and
customary supervision), then, if the Borrower designates one or more substitute
institutions to purchase the Loans and assume the Revolving Credit Commitments
of such Lender, such Lender will at the Borrower's request sell its Loans and
assign its rights under this Agreement to such substitution institutions, with
reasonable promptness after such designation in accordance with Section 10.05,
for a payment equal to the principal amount of its Loans, plus all accrued and
unpaid interest and Fees to but excluding the date of purchase, plus any other
amounts accrued or payable to such Lender under this Agreement to but excluding
the date of purchase, plus any amount that would be payable to such Lender under
Section 2.10(c) (as if such purchase were treated as a prepayment of the
outstanding Loans to such Lender), together with any other loss or expense
incurred by it (or by a Participant in the related Loans or Revolving Credit
Commitment); provided that all of the provisions of Section 10.05(b) must first
be complied with, and provided, further that the Agent may only be replaced
subject to the requirements of Section 9.13 (Successor Agent) . Nothing in this
Section 2.20 limits the rights of the Agent, the Co-Agents, the Lenders, PNC
Bank, or the L/C Issuer under any provisions of any of the Loan Documents.


                                   ARTICLE III
                   LOAN DISBURSEMENT ACCOUNT, GUARANTEES, ETC.

                  3.01. Loan Disbursement Account. The Borrower shall maintain
at all times during this Agreement with the Agent, at the Agent's office in
Pittsburgh, Pennsylvania, a 


                                     - 47 -
<PAGE>   55

demand deposit account (the "LOAN DISBURSEMENT ACCOUNT"), into which proceeds of
Revolving Credit Loans, Swingline Loans and other monies transferred to the
Borrower hereunder shall be deposited from time to time. The Loan Disbursement
Account shall be in the name of the Borrower and, subject to the other
provisions of this Agreement and the other Loan Documents, monies therein shall
be disbursed as directed by the Borrower, from time to time. To secure the
payment and performance of Lender Obligations, the Borrower hereby pledges and
assigns, and grants to the Agent for the benefit of the Agent, the L/C Issuer
and the Lenders, a lien on and security interest in the Loan Disbursement
Account, all funds from time to time deposited or held therein, all interest and
other income derived therefrom, and all proceeds of all the foregoing.

                  3.02. Designation of Subsidiary Guarantors . Each Subsidiary
of the Borrower incorporated or organized in the United States of America,
whether now in existence or hereafter acquired, that owns Receivables and
Inventory (priced at the lower of cost or market) shall be automatically
designated as a Subsidiary Guarantor by the Lenders. Any Subsidiary designated
as a Subsidiary Guarantor shall continue as a Subsidiary Guarantor until
released in writing by all Lenders.

                  3.03. Further Cooperation. The Borrower shall perform, or
cause a Subsidiary Guarantor to perform, on the reasonable request of the Agent
and at the Borrower's expense, such reasonable acts as may be necessary or
reasonably advisable to carry out the intent of this Agreement and the other
Loan Documents. Without limiting the generality of the preceding sentence, the
Borrower shall cause each newly-created or acquired Subsidiary Guarantor to
execute and deliver a Subsidiary Guaranty to the Agent with a reasonable period
of time following the creation or acquisition of such Subsidiary Guarantor.


                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

                  Representations and Warranties. The Borrower represents and

engage in the business it presently conducts or proposes to conduct; and the
Borrower is duly licensed or qualified and in good standing in each jurisdiction
listed on Schedule 4.01 hereto and in all other jurisdictions where the property
owned or leased by it or the nature of the business transacted by it makes such
licensing or qualification necessary, except for those jurisdictions where the
Borrower's non-qualification would not cause there to be a Material Adverse
Change.

                           (b)      Each Subsidiary of the Borrower is a 
corporation, business trust or limited partnership, as the case may be, duly

the case may be, shown on Schedule 4.01; each Subsidiary of the Borrower has the
lawful power to own or lease its properties and to engage in the business it
presently conducts or proposes to conduct; and each Subsidiary of the Borrower
is duly licensed or qualified and in good standing in each jurisdiction listed
on Schedule 4.01 hereto and in all other jurisdictions where the property owned
or leased by it or the nature of the business transacted by it makes such
licensing or qualification necessary, except for those jurisdictions where such
Subsidiary's non-qualification would not cause there to be a Material Adverse
Change.

                  4.02. Capitalization and Ownership. As of May 1, 1998, the
authorized capital stock of the Borrower consists of 30,000,000 shares of common
stock of which 20,410,752 shares were issued and outstanding, and 5,000,000

warrants or other rights outstanding to purchase any such capital stock.

                  4.03. Subsidiaries. Except for the Subsidiaries and
investments in other Persons set forth in Schedule 4.03, the Borrower does not
own directly or indirectly any capital stock of any other Person, is not a

corporate proceedings on its part.

                  4.05. Validity and Binding Effect. This Agreement has been,
and each Loan Document, when executed and delivered by the Borrower, will have
been, duly and validly executed and delivered by the Borrower. This Agreement
and each of the other Loan Documents executed and delivered by the Borrower will
constitute legal, valid and binding obligations of the Borrower, enforceable
against the Borrower in accordance with their respective terms, except to the
extent that enforceability of any of the Loan Documents may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforceability of creditors' rights generally or limiting the
right of specific performance.

                  4.06.    No Conflict.

                           (a)      Neither the execution and delivery by the 
Borrower of this Agreement or the Loan Documents to which the Borrower is a
party, nor the consummation of the transactions herein or therein contemplated,
nor compliance with the terms and provisions hereof or thereof by the Borrower
will (i) conflict with, constitute a default under or result in any breach of
(A) the terms and conditions of the certificate of incorporation, by-laws or
other organizational documents of the Borrower or (B) any Law or any agreement
or instrument or order, writ, judgment, injunction or decree to which the
Borrower is a party or by which it is 



                                     - 49 -
<PAGE>   57

bound or to which it is subject, which conflict, default or breach would cause a
Material Adverse Change, or (ii) result in the creation or enforcement of any
Lien upon any property (now or hereafter acquired) of the Borrower (other than
the Permitted Liens).

                           (b)      Neither the execution and delivery by a 
Subsidiary Guarantor of a Subsidiary Guaranty to which such Subsidiary Guarantor
is a party, nor the consummation of the transactions contemplated by this
Agreement or the other Loan Documents, nor compliance with the terms and
provisions hereof or thereof by such Subsidiary Guarantor will (i) conflict
with, constitute a default under or result in any breach of (A) the terms and
conditions of the articles of incorporation, by-laws or other organizational
documents of such Subsidiary or (B) any Law or any agreement or instrument or
order, writ, judgment, injunction or decree to which such Subsidiary is a party
or by which it is bound or to which it is subject, which conflict, default or
breach would cause a Material Adverse Change, or (ii) result in the creation or
enforcement of any Lien upon any property (now or hereafter acquired) of such
Subsidiary (other than the Permitted Liens).

                  4.07. Litigation. Except for the litigation set forth on
Schedule 4.07, there are no actions, suits, proceedings or investigations
pending or, to the knowledge of the Borrower, threatened against the Borrower or
any Subsidiary of the Borrower, at law or in equity, before any Official Body
which individually or in the aggregate, if adversely determined, would be likely
to result in any Material Adverse Change. Neither the Borrower nor any
Subsidiary of the Borrower is in violation of any order, writ, injunction or
decree of any Official Body which could be expected to result in any Material
Adverse Change.

                  4.08.    Financial Statements.

                           (i)      Financial Statements. The Borrower has 
delivered to the Agent the consolidated annual financial statements of the
Borrower and its Subsidiaries for the Fiscal Year ended December 31, 1997, and
the consolidated quarterly financial statements of the Borrower and its
Subsidiaries for the Fiscal Quarter ended March 31, 1998. All such financial
statements are complete and correct in all material respects and fairly present
the consolidated financial condition of the Borrower and its Subsidiaries in all
material respects and the results of their operations as of the dates and for
the periods referred to, and have been prepared in accordance with GAAP
throughout the period included.

                           (ii)     Accuracy of Financial Statements. The 
Borrower and its Subsidiaries have no liabilities, contingent or otherwise, that
are not disclosed in the financial statements referred to in clause (i) above
and that would be required to be disclosed in accordance with GAAP, except for
those incurred since the date of such financial statements in the ordinary
course of business.

                  4.09. Margin Stock; Section 20 Subsidiaries. Neither the
Borrower nor any of its Subsidiaries engage or intend to engage principally, or
as one of its important activities, in the business of incurring Indebtedness or
extending credit to others (including, without limitation, any of the
Subsidiaries of the Borrower) for the purpose, immediately, incidentally or
ultimately, of purchasing or carrying margin stock (within the meaning of any
Margin 


                                     - 50 -
<PAGE>   58

Regulation). No part of the proceeds of any Revolving Credit Loan or Swingline
Loan has been or will be used, immediately, incidentally or ultimately, to
purchase or carry any margin stock or to extend credit to others (including,
without limitation, any of its Subsidiaries) for the purpose of purchasing or
carrying any margin stock or to refund or retire Indebtedness originally
incurred for such purpose, or for any purpose which entails a violation of or
which is inconsistent with the provisions of the Margin Regulations of the Board
of Governors of the Federal Reserve System. The Borrower does not intend to
hold, and shall not permit its Subsidiaries to hold, margin stock. Neither the
Borrower not any of its Subsidiaries intends to use any portion of the proceeds
of the Loans, directly or indirectly, to purchase during the underwriting
period, or for thirty (30) days thereafter, Ineligible Securities being
underwritten by a Section 20 Subsidiary.

                  4.10. Full Disclosure. Neither this Agreement nor any Loan
Document, nor any certificate, statement, agreement or other document furnished
to the Agent, the L/C Issuer or any Lender in connection herewith or therewith,
contains any misstatement of a material fact or omits to state a material fact
necessary in order to make the statements contained herein and therein, in light
of the circumstances under which they were made, not misleading. There is no
fact known to the Borrower which materially adversely affects the business,
property, assets, financial condition, results of operations or prospects of the
Borrower and its Subsidiaries, taken as a whole, which has not been set forth in
this Agreement or the Loan Documents or in the certificates, statements,
agreements or other documents furnished in writing to the Agent, the Lenders or
the L/C Issuer prior to or at the date hereof in connection with the
transactions contemplated hereby and thereby.

                  4.11. Tax Returns and Payments. The Borrower is a member of an
affiliated group of companies which files consolidated federal tax returns. All
such federal tax returns that are required by law to be filed have been filed or
properly extended. All taxes, assessments and other governmental charges levied
upon members of such affiliated group or any of their respective properties,
assets, income or franchises which are due and payable have been paid in full
other than (i) those presently payable without penalty or interest, (ii) those
which are being contested in good faith by appropriate proceedings and (iii)
those which, if not paid, would not, in the aggregate, constitute a Material
Adverse Change; and as to each of items (i), (ii) and (iii) the affiliated group
has established reserves for such claim as have been determined to be adequate
by application of GAAP consistently applied. There are no agreements or waivers
extending the statutory period of limitations applicable to any consolidated
federal income tax return of the Borrower and its consolidated Subsidiaries for
any period, except as set forth on Schedule 4.11.

                  4.12. Consents and Approvals. No consent, approval, exemption,
order or authorization of, or a registration or filing with any Official Body or
any other Person is required by any Law or any agreement in connection with the
execution, delivery and carrying out of this Agreement and the Loan Documents to
which the Borrower or any Subsidiary Guarantor is a party, except as listed on
Schedule 4.12 attached hereto, all of which items set forth on Schedule 4.12
shall have been obtained or made on or prior to the Closing Date.



                                     - 51 -
<PAGE>   59

                  4.13. No Event of Default; Compliance with Instruments. No
event has occurred and is continuing and no condition exists or will exist after
giving effect to the borrowings to be made on the Closing Date under the Loan
Documents which constitutes an Event of Default or a Default. Neither the
Borrower nor any of its Subsidiaries is in violation of (i) any term of its
certificate of incorporation, by-laws or other organizational documents or (ii)
any material agreement or instrument to which it is a party or by which it or
any of its properties may be subject or bound where such violation would
constitute a Material Adverse Change.

                  4.14. Compliance with Laws. The Borrower and its Subsidiaries
are in compliance in all material respects with all applicable Laws (other than
Environmental Laws, which are addressed in Section 4.20) in all jurisdictions in
which the Borrower, and its Subsidiaries, are presently or will be doing
business except where the failure to do so would not, individually or in the
aggregate, constitute a Material Adverse Change.

                  4.15. Investment Company; Public Utility Holding Company.
Neither the Borrower nor any Subsidiary Guarantor is an "investment company"
registered or required to be registered under the Investment Company Act of 1940
or under the "control" of an "investment company" as such terms are defined in
the Investment Company Act of 1940, as amended from time to time, and shall not
become such an "investment company" or under such "control. " Neither the
Borrower nor any Subsidiary Guarantor is a "holding company" or a "subsidiary
company" of a "holding company" or an "affiliate" of a "holding company" within
the meaning the Public Utility Holding Company Act of 1935, as amended from time
to time. The Borrower is not subject to any Law of any Official Body (in each
case whether United States federal, state or local, or other) having
jurisdiction over the Borrower, which purports to restrict or regulate its
ability to borrow money, or to extend or obtain credit, or to pledge its
interests in the Loan Disbursement Account. No Subsidiary Guarantor is subject
to any Law of any Official Body (in each case whether United States federal,
state or local, or other) having jurisdiction over such Subsidiary Guarantor
which purports to restrict or regulate its ability to borrow money or to extend
or obtain credit.

                  4.16.    Plans and Benefit Arrangements. Except as set forth 
on Schedule 4.16 hereto:

                           (i)      The Borrower and each member of the ERISA 
Group are in compliance in all material respects with any applicable provisions
of ERISA with respect to all Benefit Arrangements, Plans and Multiemployer
Plans. There has been no Prohibited Transaction with respect to any Benefit
Arrangement or any Plan (other than a Multiemployer Plan) or, to the knowledge
of the Borrower, with respect to any Multiemployer Plan or Multiple Employer
Plan, which could result in any material liability of the Borrower or any other
member of the ERISA Group. The Borrower and all members of the ERISA Group have
made when due any and all payments required to be made under any agreement
relating to a Multiemployer Plan or a Multiple Employer Plan or any Law
pertaining thereto. With respect to each Plan and, to the knowledge of Borrower,
each Multiemployer Plan, the Borrower and each member of the ERISA Group (i)
have fulfilled in all material respects their obligations under the minimum
funding standards of ERISA, (ii) have not incurred any liability to the PBGC
(other than for premiums not yet due) and (iii) have not had asserted against
them any penalty for failure to fulfill the minimum funding requirements of
ERISA.


                                     - 52 -
<PAGE>   60

                           (ii)     To the best of the Borrower's knowledge, 
each Multiemployer Plan and Multiple Employer Plan is able to pay benefits
thereunder when due.

                           (iii)    Neither the Borrower nor any other member 
of the ERISA Group has instituted or intends to institute proceedings to
terminate any Plan.

                           (iv)     No event requiring notice to the PBGC under
Section 302(f)(4)(A) of ERISA has occurred or is reasonably expected to occur
with respect to any Plan, and no amendment with respect to which security is
required under Section 307 of ERISA has been made or is reasonably expected to
be made to any Plan.

                           (v)      Neither the Borrower nor any other member of
the ERISA Group has incurred or reasonably expects to incur any material
withdrawal liability under ERISA to any Multiemployer Plan or Multiple Employer
Plan. Neither the Borrower nor any other member of the ERISA Group has been
notified by any Multiemployer Plan or Multiple Employer Plan that such
Multiemployer Plan or Multiple Employer Plan has been terminated within the
meaning of Title IV of ERISA and, to the knowledge of the Borrower, no
Multiemployer Plan or Multiple Employer Plan is reasonably expected to be
reorganized or terminated, within the meaning of Title IV of ERISA.

                           (vi)     To the extent that any Benefit Arrangement 
is insured, the Borrower and all members of the ERISA Group have paid when due
all premiums required to be paid for all periods ending through and including
the Closing Date. To the extent that any Benefit Arrangement is funded other
than with insurance, the Borrower and all members of the ERISA Group have made
when due all contributions, to the extent required by applicable Law or the
terms of such Benefit Arrangement to be paid for all periods ending through and
including the Closing Date.

                  4.17. Title to Properties. The Borrower and each of its
Subsidiaries have good title to, or a valid leasehold interest in, all their
respective real and personal property, except to the extent the failure to have

abandoned underground storage tanks or underground piping associated with such
tanks, previously used for the management of Regulated Substances at, on or
under the Property that have not been either abandoned in place, or removed, in
accordance with the Environmental Laws, other than those with respect to which

aggregate, to result in a Material Adverse Change. The Borrower and each
Subsidiary of the Borrower have submitted all notices, reports and other filings
required by the Environmental Laws to be submitted to an Official Body which
pertain to past and current operations on the Property, except for any failure
to submit which would not be reasonably likely to result in a Material Adverse
Change.

and in the aggregate are not likely to result in a Material Adverse Change, all

payment with all other Indebtedness of the Borrower, except Indebtedness of the
Borrower to the extent secured by Permitted Liens. The obligations of a
Subsidiary Guarantor under a Subsidiary Guaranty executed by such Subsidiary
Guarantor rank at least pari passu in priority of payment with all other
Indebtedness of such Subsidiary Guarantor except Indebtedness of such Subsidiary
Guarantor to the extent secured by Permitted Liens. There is no Lien upon or
with respect to any of the properties or income of the Borrower or any of its

as and when the same shall become due and payable, including all taxes,
assessments and governmental charges upon them or any of their properties,
assets, income or profits, prior to the date on which penalties attach thereto;
provided, however, the Borrower may choose not to pay any such liabilities,
including taxes, assessments or charges, if the same are being contested in good
faith and for which such reserves (including reserves for any additional amounts
which would be payable as a result of the failure to discharge timely any such
liabilities) or other appropriate provisions, if any, as shall be required by

                  6.08. Visitation Rights. The Borrower shall permit, and shall

shall cause each member of the ERISA Group to, comply with ERISA, the Internal
Revenue Code and other applicable Laws applicable to Plans and Benefit
Arrangements except where such failure, alone or in conjunction with any other
failure, would not result in a Material Adverse Change. Without limiting the
generality of the foregoing, the Borrower shall cause all of its Plans and all
Plans maintained by any member of the ERISA Group to be funded in accordance
with the minimum funding requirements of ERISA and shall make, and cause each
member of the ERISA Group to make, in a timely manner, all contributions due to
Plans, Benefit Arrangements and Multiemployer Plans.

                  6.11. Compliance with Laws. The Borrower and its Subsidiaries
shall comply with all applicable Laws (other than Environmental Laws) in all
respects, provided that they shall not be deemed to be a violation of this
Section 6.11 if any failure to comply with any Law would not result in fines,
penalties, other similar liabilities or injunctive relief which in the aggregate
would constitute a Material Adverse Change.

                  6.12. Use of Proceeds. The Borrower will use the proceeds of
the Loans only for lawful purposes in accordance with Section 2.16 hereof as
applicable and such uses shall not contravene any applicable Law or any other
provision hereof. The Borrower will permit the use of the Letters of Credit only

conduct and complete in all material respects all investigations, studies,
sampling and testing, and all remedial, removal and other actions required under
Environmental Laws and promptly comply in all material respects with all lawful
orders and directives of all Official Bodies respecting Environmental Laws,
except to the extent that the same are being contested in good faith by
appropriate and lawful proceedings diligently conducted and for which such
reserves or other appropriate provisions, if any, required by GAAP shall have
been made; and

                           (iii)    The Borrower shall defend, indemnify and 
hold harmless the Agent and the Lenders, and their respective employees, agents,

Subsidiaries, or any orders, requirements or demands of any Official Bodies
related thereto, including, without limitation, reasonable attorney's and
consultant's fees, investigation and laboratory fees, court costs and litigation
expenses, except to the extent that any of the foregoing arise out of the gross
negligence or willful misconduct of the party seeking indemnification therefor.

                  6.14. Senior Debt Status. The obligations of the Borrower
under this Agreement and the Notes will rank at least pari passu in priority of
payment with all other Indebtedness of the Borrower except Indebtedness of the

Subsidiary Guarantor under the Subsidiary Guaranty, executed by it will rank at
least pari passu in priority of payment with all other Indebtedness of such
Subsidiary Guarantor except Indebtedness of such Subsidiary Guarantor to the
extent secured by Permitted Liens.

or become or be declared ineffective or inoperative or shall in any way be
challenged or contested or cease to give or provide the respective rights,

Letters of Credit hereunder; and

                           (c)      If an Event of Default shall occur and be 
continuing, any Lender, the Agent or the L/C Issuer to whom any obligation is
owed by the Borrower hereunder or under any other Loan Document, of such Lender,
Agent or L/C Issuer and any branch, subsidiary or affiliate of such Lender,
Agent or L/C Issuer anywhere in the world shall each have the right, in addition
to all other rights and remedies available to it, without notice to the
Borrower, to set-off against and apply to the then unpaid balance of all the
Loans and all other obligations of the Borrower hereunder or under any other
Loan Document, any debt owing to, and any other funds held in any manner for the
account of, the Borrower by such Lender, the Agent or the L/C Issuer or by such

                                     - 75 -

limitation, all funds in all deposit accounts (whether time or demand, general
or special, provisionally credited or finally credited, or otherwise) now or
hereafter maintained by the Borrower for its own account (but not including
funds held in custodian or trust accounts) with such Lender, the Agent or the
L/C Issuer or such branch, subsidiary or affiliate. Such right shall exist in
each case whether or not any Lender, the Agent or the L/C Issuer shall have made
any demand under this Agreement or any other Loan Document, whether or not such
debt owing to or funds held for the account of the Borrower is or are matured or
unmatured and regardless of the existence or adequacy of any other security,
right or remedy available to any Lender, the Agent or the L/C Issuer; and

the Required Lenders of any other Event of Default and the termination of the
Revolving Credit Commitments, the obligation of the L/C Issuer to issue or amend
Letters of Credit shall terminate, the L/C Issuer or the Agent may provide
written demand to any beneficiary of a Letter of Credit to present a draft
against such Letter of Credit, and an amount equal to the maximum amount which
may at any time be drawn under the Letters of Credit then outstanding (whether
or not any beneficiary of such Letters of Credit shall have presented, or shall
be entitled at such time to present, the drafts or other documents required to
draw under the Letters of Credit) shall automatically become immediately due and
payable, without presentment, demand, protest or other requirements of any kind,
all of which are hereby expressly waived by the Borrower; provided that the
foregoing shall not affect in any way the obligations of the Lenders to purchase
from the L/C Issuer participations in the unreimbursed amount of any drawings
under the Letters of Credit as provided in Section 2.17(c). So long as the
Letters of Credit shall remain outstanding, any amounts declared due pursuant to
this Section 8.02(e) with respect to the outstanding Letters of Credit when
received by the Agent shall be deposited and held by the Agent in an interest
bearing account denominated in the name of the Agent for the benefit of the
Agent, the Lenders and the L/C Issuer over which the Agent shall have sole
dominion and control of withdrawals (the "CASH COLLATERAL ACCOUNT") as cash
collateral for the obligation of the Borrower to reimburse the L/C Issuer in the
event of any drawing under the Letters of Credit and upon any drawing under such
Letters of Credit in respect of which the Agent has deposited in the Cash
Collateral Account any amounts declared due pursuant to this Section 8.02(e),
the Agent shall apply such amounts held by the Agent to reimburse the L/C Issuer
for the amount of such drawing. In the event that any Letter of Credit in
respect of which the Agent has deposited in the Cash Collateral Account any
amounts described above is cancelled or expires or in the event of any reduction
in the maximum amount available at any time for drawing under the Letters of
Credit outstanding, the Agent shall apply the amount then in the Cash Collateral
Account designated to reimburse the L/C Issuer for any drawings under the



                                     - 76 -
<PAGE>   84

Letters of Credit less the maximum amount available at any time for drawing
under the Letters of Credit outstanding immediately after such cancellation,
expiration or reduction, if any, to the payment in full of the outstanding
Lender Obligations, and second, to the payment of any excess, to the Borrower.


                                   ARTICLE IX
                                   THE AGENTS

                  9.01. Appointment and Grant of Authority. Each of the Lenders
and the L/C Issuer hereby appoints PNC Bank, National Association, and PNC Bank,
National Association, hereby agrees to act, as the Agent under this Agreement
and the other Loan Documents. Each of the Lenders and the L/C Issuer hereby
appoints each of National City Bank of Pennsylvania and Bank One, National
Association as Co-Agent hereunder. The Agent shall have and may exercise such
powers under this Agreement and the other Loan Documents as are specifically
delegated to it by the terms hereof or thereof, together with such other powers
as are incidental thereto. Without limiting the foregoing, the Agent, on behalf
of the Lenders and the L/C Issuer, is authorized to execute all of the Loan
Documents (other than this Agreement) and to accept all of the Loan Documents
and all other agreements, documents or instruments reasonably required to carry
out the intent of the parties to this Agreement.

                  9.02. Delegation of Duties. The Agent may perform any of its
duties hereunder by or through agents or employees (provided such delegation
does not constitute a relinquishment of duties as the Agent hereunder) and,
subject to Sections 9.07 and 10.03 hereof, shall be entitled to engage and pay
for the advice or services of any attorneys, accountants, or other experts
concerning all matters pertaining to duties hereunder and to rely upon any
advice so obtained.

                  9.03. Reliance by Agent on Lenders for Funding. Unless the
Agent shall have received notice from a Lender prior to any Borrowing Date that
such Lender will not make available to the Agent such Lender's portion of net
disbursements of Loans, the Agent may assume that such Lender has made such
portion available to the Agent and the Agent may, in reliance upon such
assumption, make Loans to the Borrower. If and to the extent that such Lender
has not made such portion available to the Agent on or prior to any Borrowing
Date, such Lender and the Borrower severally agree to repay to the Agent
immediately upon demand, in immediately available funds, such unpaid amount,
together with interest thereon for each day from the applicable Borrowing Date
until such amount is repaid to the Agent, at (i) in the case of the Borrower, at
the rate of interest then in effect for such Loan and (ii) in the case of such
Lender, at the Federal Funds Effective Rate. If such Lender shall repay to the
Agent such corresponding amount, such amount shall constitute a Loan made by
such Lender for purposes of this Agreement. The failure by any Lender to pay its
portion of a Revolving Credit Loan made by the Agent shall not relieve any other
Lender of the obligation to pay its portion of net disbursements of Revolving
Credit Loans on any Borrowing Date, but no Lender shall be responsible for the
failure of any other Lender to make its net share of Revolving Credit Loans to
be made by such other Lender on such Borrowing Date.



                                     - 77 -
<PAGE>   85

                  9.04. Non-Reliance on Agents. Each Lender and the L/C Issuer
agree that (i) it has, independently and without reliance on the Agent or the
Co-Agents, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of the Borrower and its Subsidiaries
and decision to enter into this Agreement and (ii) that it will, independently
and without reliance upon the Agent or the Co-Agents, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own analysis and decisions in taking or not taking action under this
Agreement. Except as otherwise provided herein or under any other Loan Document,
neither the Agent nor any Co-Agent shall have any duty to keep the Lenders or
the L/C Issuer informed as to the performance or observance by the Borrower of
this Agreement or any other document referred to or provided for herein or to
inspect the properties or books of the Borrower or any of its Subsidiaries. The
Agent and the Co-Agents, in the absence of gross negligence or willful
misconduct, shall not be liable to any Lender or the L/C Issuer for their
failure to relay or furnish to the Lender any information.

                  9.05.    Responsibility of Agents and Other Matters.

                           (a)      Ministerial Nature of Duties. As between 
the Lenders, the L/C Issuer and itself, the Agent shall not have any duties or
responsibilities except those expressly set forth in this Agreement or in the
other Loan Documents, and those duties and responsibilities shall be subject to
the limitations and qualifications set forth in this Article IX. The duties of
the Agent shall be ministerial and administrative in nature. The Co-Agents shall
have no duties as agents hereunder.

                           (b)      Limitation of Liability. As between the 
Lenders, the L/C Issuer, the Agent and the Co-Agents, neither the Agent nor
either Co-Agent nor any of their respective directors, officers, employees or
agents shall be liable, in the absence of gross negligence or willful
misconduct, for any action taken or omitted (whether or not such action taken or
omitted is within or without the Agent's responsibilities and duties expressly
set forth in this Agreement) under or in connection with this Agreement or any
other instrument or document in connection herewith. Without limiting the
foregoing, neither the Agent nor either Co-Agent nor any of their representative
directors, officers, employees or its agents, shall be responsible for, or have
any duty to examine (i) the genuineness, execution, validity, effectiveness,

                           (c)      Reliance. The Agent shall be entitled to 
act, and shall be fully protected in acting upon, any telegram, telex, teletype,
telecopy, bank wire or cable or any writing, application, notice, report,
statement, certificate, resolution, request, order, consent, letter or other
instrument or paper or communication believed by the Agent in good faith to be
genuine and correct and to have been signed or sent or made by a proper Person.
The Agent may consult counsel and shall be entitled to act, and shall be fully
protected in any action taken in good faith, in accordance with advice given by
counsel. The Agent may employee agents and attorneys-in-fact and shall not be
liable for the default or misconduct of any such agents or attorneys-in-fact
selected by the Agent with reasonable care. The Agent shall not be bound to
ascertain or inquire as to the performance or observance of any of the terms,
provisions or conditions of this Agreement or any of the other Loan Documents on
the part of the Borrower.

                  9.06. Actions in Discretion of Agent; Instructions from the
Lenders. The Agent agrees, upon the written request of the Required Lenders, to
take or refrain from taking any action of the type specified as being within the
Agent's rights, powers or discretion herein or under any Loan Documents,
provided that the Agent shall not be required to take any action which exposes
the Agent to personal liability or which is contrary to this Agreement or any
other Loan Document or applicable Law. In the absence of a request by the
Required Lenders, the Agent shall have authority, in its sole discretion, to
take or not to take any such action, unless this Agreement specifically requires
the consent of the Required Lenders or all of the Lenders. Any action taken or
failure to act pursuant to such instructions or discretion shall be binding on
the Lenders and the L/C Issuer, subject to Section 9.05(b) hereof. Subject to
the provisions of Section 9.05(b), no Lender shall have any right of action
whatsoever against the Agent as a result of the Agent acting or refraining from
acting hereunder in accordance with the instructions of the Required Lenders.

                  9.07. Indemnification. To the extent the Borrower does not
reimburse and save harmless the Agent or the Co-Agents according to the terms
hereof for and from all costs, expenses and disbursements in connection
herewith, such costs, expenses and disbursements, shall be borne by the Lenders
ratably in accordance with respective Lender's Ratable Share. Each Lender hereby
agrees on such basis (i) to reimburse the Agent and the Co-Agents for such
Lender's Ratable Share of all such reasonable costs, expenses and disbursements
on request and (ii) to the extent of each such Lender's Ratable Share, to
indemnify and save harmless the Agent and the Co-Agents against and from any and
all losses, obligations, penalties, actions, judgments and suits and other
costs, expenses and disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against the Agent and the Co-Agents, other
than as a consequence of gross negligence or willful misconduct on the part of
the Agent and the Co-Agents, arising out of or in connection with this
Agreement, the other Loan Documents or any other agreement, instrument or
document in connection herewith or therewith, or any request of the Required
Lenders, including without limitation the reasonable costs, expenses and
disbursements in connection with defending itself against any claim or liability
related to the exercise or performance of any of its powers or duties under this
Agreement, the other Loan Documents, or any of the other agreements, instruments
or documents delivered in connection herewith or the taking of any action under
or in connection with any of the foregoing.

                  9.08. Agents' Rights as Lenders. With respect to the Revolving
Credit Commitment of the Agent and the Co-Agents as Lenders hereunder, any Loans
of the Agent or the Co-Agents under this Agreement, the Agent's and the
Co-Agents' Ratable Share of any Unreimbursed L/C Draws, the participation as a
Lender, and as to PNC Bank, as the L/C Issuer under this Agreement the other
Loan Documents and any other agreements, instruments and documents delivered
pursuant hereto, and the issuance of any Letter of Credit under the terms
hereof, the Agent and the Co-Agents shall have the same rights and powers,
duties and obligations under this Agreement, the other Loan Documents or any
other agreement, instrument or document as any Lender and may exercise such
rights and powers and shall perform such duties and fulfill such obligations as
though it were not the Agent, as the case may be. The Agent and the Co-Agents
may accept deposits from, lend money to, and generally engage, and continue to
engage, in any kind of business with the Borrower or any of its Subsidiaries.

                  9.09. Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of an Event of Default unless the Agent
has received written notice from a Lender or the Borrower referring to this
Agreement, describing such Event of Default and stating that such notice is a
"notice of default".

                  9.10. Payment to Lenders. Except as otherwise set forth in
Section 9.03 hereof, promptly after receipt from the Borrower of any principal
repayment of the Revolving Credit Loans or any Unreimbursed L/C Draw, interest
due on the Revolving Credit Loans or any Unreimbursed L/C Draws, and any Fees
(other than the underwriting fee and the administration fee paid to the Agent
and the L/C Fronting Fee paid to the L/C Issuer) or other amounts due under any
of the Loan Documents, the Agent shall distribute to each Lender that Lender's
Ratable Share of the funds so received except that funds received from the
Borrower or a Subsidiary Guarantor to reimburse the L/C Issuer for drawings on
Letters of Credit (other than a Lender's Ratable Share of such reimbursement
payment to the extent such Lender has complied fully with any funding
obligations under Section 2.17(g) hereof) or to fund any risk participant in the
Letters of Credit or to pay the L/C Fronting Fee shall be paid solely for the
account of L/C Issuer. If the Agent fails to distribute collected funds received
by 2:00 P.M. on any Business Day by 3:00 P.M. of such Business Day or collected
funds received after 2:00 P.M. on any Business Day by 3:00 P.M. the next
Business Day the funds shall bear interest until distributed at the Federal
Funds Effective Rate. The Agent agrees to make its best efforts to provide
telephonic notice to each Lender that it is in receipt of funds from the
Borrower and the day on which it will commence a wire transfer of such Lender's
share of such funds.

                  9.11. Holders of Notes. The Agent may deem and treat any payee
of any Note as the owner thereof for all purposes hereof unless and until
written notice of the assignment or transfer thereof shall have been filed with
the Agent. Any request, authority or consent of any person who at the time of
making such request or giving such authority or consent is the holder of any
Note shall be conclusive and binding on any subsequent holder, transferee or
assignee of such Note or of any Note or Notes issued in exchange therefor.

<PAGE>   88

                  9.12. Equalization of Lenders. Each borrowing and each payment
or prepayment by, or for the account of, the Borrower with respect to principal,
interest, Fees, or other amounts due from the Borrower hereunder to the Lenders
with respect to the Revolving Credit Loans, shall (except as provided in Section
2.10, 2.12, 2.17(b) or 9.03 hereof) be made in proportion to the Revolving
Credit Loans outstanding from each Lender or, if no such Revolving Credit Loans
are then outstanding, in proportion to the Ratable Share of each Lender. Each
payment of Unreimbursed L/C Draws shall be made for the account of the L/C
Issuer. The Lenders agree among themselves that, with respect to all amounts
received by any Lender (in its capacity solely as a Lender) or any such holder
for application on any obligation hereunder or under any Note or under any such
participation, whether received by voluntary payment, by realization upon
security, by the exercise of the right of set-off or banker's lien, by
counterclaim or by any other non-pro rata source, equitable adjustment will be
made in the manner stated in the following sentence so that, in effect, all such
excess amounts will be shared ratably among the Lenders and such holders in
proportion to their interest in payments under the Notes, except as otherwise
expressly provided herein. The Lenders or any such holder receiving any such
amount shall purchase for cash, from each of the other Lenders, an interest in
such Lender's Revolving Credit Loans in such amount as shall result in a ratable
participation by the Lenders and each such holder in the aggregate unpaid amount
under the Notes, provided that if all or any portion of such excess amount is
thereafter recovered from the Lender or the holder making such purchase, such
purchase shall be rescinded and the purchase price restored to the extent of
such recovery, together with interest or other amounts, if any, required by Law
(including court order) to be paid by the Lender or the holder making such
purchase.

                  9.13. Successor Agent. The Agent may resign as the Agent upon
sixty (60) days' written notice to the Lenders and the Borrower. If such notice
shall be given, the Lenders shall appoint from among the Lenders a successor
agent for the Lenders, during such 60-day period, which successor agent shall be
reasonably satisfactory to the Borrower, to serve as agent hereunder and under
the several documents, the forms of which are attached hereto as exhibits, or
which are referred to herein. If at the end of such 60-day period the Lenders
have not appointed such a successor, the Agent shall procure a successor
reasonably satisfactory to the Lenders and the Borrower, to serve as agent for
the Lenders hereunder and under the several documents, the forms of which are
attached hereto as exhibits, or which are referred to herein. Any such successor
agent shall succeed to the rights, powers and duties of the Agent. Upon the
appointment of such successor agent or upon the expiration of such 60-day period
(or any longer period to which the Agent has agreed), the former Agent's rights,
powers and duties as Agent shall be terminated, without any other or further act
or deed on the part of such former Agent or any of the parties to this
Agreement. After any retiring Agent's resignation hereunder as the Agent, the
provisions of this Article IX shall inure to the benefit of such retiring Agent
as to any actions taken or omitted to be taken by it while it was the Agent
under this Agreement. A Co-Agent may resign upon ten (10) days prior written
notice to the Agent.

                  9.14. Calculations. In the absence of gross negligence or
willful misconduct, the Agent shall not be liable for any error in computing the
amount payable to any Lender whether in respect of the Revolving Credit Loans,
fees or any other amounts due to the 


                                     - 81 -
<PAGE>   89

Lenders or the L/C Issuer under this Agreement. In the event an error in
computing any amount payable to any Lender or the L/C Issuer is made, the Agent,
the Borrower and each affected Person shall, forthwith upon discovery of such
error, make such adjustments as shall be required to correct such error, and any
compensation therefor will be calculated at the Federal Funds Effective Rate.

                  9.15. Beneficiaries. Except as expressly provided herein, the
provisions of this Article IX are solely for the benefit of the Agent, the
Co-Agents, the Lenders and the L/C Issuer, and the Borrower shall not have any
rights to rely on or enforce any of the provisions hereof. In performing its
functions and duties under this Agreement, the Agent shall act solely as agent
of the Lenders and does not assume and shall not be deemed to have assumed any
obligation toward or relationship of agency or trust with or for the Borrower.


                                    ARTICLE X
                               GENERAL PROVISIONS

Agent with the consent in writing of the Required Lenders, and the Borrower may,
subject to the provisions of this Section 10.01, from time to time enter into

for the purpose of adding or deleting any provisions or otherwise changing,

any of its Subsidiaries, but only to the extent specified in such written
agreements; provided, however, that no such supplemental agreement shall,
without the consent of all the Lenders:

                           (i)      waive an Event of Default by the Borrower 
in any payment of principal, interest, Fees or other amounts due hereunder and

the interest rate relating to the Revolving Credit Loans;

                           (iii)    change the Long-Term Expiration Date or 
the Short-Term Expiration Date;

                           (iv)     reduce any Fee;

                  Any such supplemental agreement shall apply equally to each of
the Lenders and the L/C Issuer and shall be binding upon the Borrower, the
Lenders, the Agent and the Co-Agents, all future holders of the Notes and all
Participants. In the case of any waiver, the Borrower, the Lenders, the L/C
Issuer, the Agent and the Co-Agents shall be restored to former positions and
rights, and any Event of Default waived shall be deemed to be cured and not
continuing, but no such waiver shall extend to any subsequent or other Event of
Default, or impair any right consequent thereon.

                  10.02. Taxes. The Borrower shall pay any and all stamp,
document, transfer and recording taxes, filing fees and similar impositions
payable or hereafter determined by the Agent, the Co-Agents, the Lenders or the
L/C Issuer to be payable in connection with this Agreement, the other Loan
Documents and any other documents, instruments and transactions pursuant to or
in connection with any of the Loan Documents. The Borrower agrees to save the
Agent, the Co-Agents, the Lenders and the L/C Issuer harmless from and against
any and all present and future claims or liabilities with respect to, or
resulting from, any delay in paying or failure to pay any such taxes or similar
impositions.

                                    (i)     pay or reimburse the Agent for all 
reasonable out-of-pocket costs and expenses incurred by the Agent in connection

transactions contemplated hereby and thereby (including, without limitation, in
each case the reasonable fees and out-of-pocket expenses of the counsel to the
Agent); and

                                    (ii)    reimburse the Agent, the Co-Agents, 
the L/C Issuer and each Lender on demand for all reasonable out-of-pocket costs

                           (b)      Assignments. Subject to the remaining 
provisions of this Section 10.05(b), any Lender may at any time, in the ordinary
course of its commercial lending business, in accordance with applicable law,
sell to one or more Purchasing Lenders (which Purchasing Lender may be
affiliates of the Transferor Lender), all or a portion of its rights and
obligations under this Agreement and the Note then held by it, pursuant to an
Assignment and Assumption Agreement substantially in the form of Exhibit "E" and
satisfactory to the Agent, executed by the Transferor Lender, such Purchasing
Lender, the Agent and the Borrower; subject, however to the following
requirements:

                                    (i)     The Agent and the Borrower must 
each give its prior consent to any such assignment which consent shall not be
unreasonably withheld; it being agreed that it shall not be deemed unreasonable
for the Borrower to decline to consent to such assignment if (A) such assignment
would result in incurrence of additional costs to the Borrower under Section
2.10, 2.11 or 2.12, or (B) the proposed assignee has not provided to the
Borrower any tax forms received under Section 10.05(d); provided, however, no
consent is required for the transfer by a Lender to its Affiliate so long as the
conditions in clauses (A) and (B) immediately above are satisfied;

                                    (ii)    Each such assignment must be in a
minimum amount of $5,000,000, or, if in excess of $5,000,000, in integral
multiples of $1,000,000;

                                    (iii)    each such assignment shall be of a
constant, and not a varying, percentage of the Transferor Lender's Long-Term
Revolving Credit Commitment, Short-Term Revolving Credit Commitment, outstanding
Revolving Credit Loans and all other rights and obligations under this Agreement
and the other Loan Documents; and

                                    (iv)    The Transferor Lender shall pay to 
the Agent, for its own Account, a fee of $3,500 for each such assignment (the
"ASSIGNMENT FEE").

                  Upon the execution, delivery, acceptance and recording of any
such Assignment and Assumption Agreement, from and after the Transfer Effective
Date determined pursuant to such Assignment and Assumption Agreement, (i) the
Purchasing Lender thereunder shall be a party hereto as a Lender and, to the
extent provided in such Assignment and Assumption Agreement, shall have the
rights and obligations of a Lender hereunder with a Revolving Credit Commitment
as set forth therein, and (ii) the Transferor Lender thereunder shall, to the
extent provided in such Assignment and Assumption Agreement, be released from
its obligations under this Agreement as a Lender. Such Assignment and Assumption
Agreement shall be deemed to amend this Agreement to the extent, and only to the
extent, necessary to reflect the addition of such Purchasing Lender as a Lender
and the resulting adjustment of Ratable Share arising from the purchase by such
Purchasing Lender of all or a portion of the rights and obligations of such
Transferor Lender under this Agreement and the Notes. On or prior to the
Transfer Effective Date, the Borrower shall execute and deliver to the Agent, in
exchange for the surrendered Notes held by the Transferor Lender, new Notes to
the order of such Purchasing Lender in an amount equal to the Long-Term
Revolving Credit Commitment and Short-Term Revolving Credit Commitment assumed
by it and purchased by it pursuant to such Assignment and Assumption Agreement,
and new Notes to the order of the Transferor Lender in an amount equal to the
Long-Term Revolving Credit Commitment and Short-Term Revolving Credit Commitment
retained by it hereunder.

                           (c)      Assignment Register. The Agent shall 
maintain at its address referred to in Section 10.04(b) a copy of each
Assignment and Assumption Agreement delivered to it and a register (the
"Register") for the recordation of the names and addresses of the Lenders and
the amount of the Revolving Credit Loans owing to each Lender from time to time.
The entries in the Register shall be conclusive, in the absence of manifest
error, and the Borrower, the Agent, the Lender and the L/C Issuer may treat each
Person whose name is recorded in the Register as the owner of the Revolving
Credit Loans recorded therein for all purposes of this Agreement. The Register
shall be available at the office of the Agent for inspection by the Borrower or
any Lender at any reasonable time and from time to time upon reasonable prior
notice.

                           (d)      Withholding of Income Taxes. At least five 
(5) Business Days prior to the first date on which interest or fees are payable
hereunder for the account of any Purchasing Lender or Participant, each
Purchasing Lender or Participant that is not incorporated under the laws of the
United States or a state thereof shall deliver to the Borrower and the
Transferor Lender two duly completed copies of United States Internal Revenue
Service Form W-9, 4224 or 1001 or other applicable form prescribed by the
Internal Revenue Service. Such form shall certify that such Purchasing Lender or
Participant is entitled to receive payments under this Agreement and the Notes
without deduction or withholding of any United States Federal income taxes, or
is subject to such tax at a reduced rate under an applicable tax treaty or under
United States Internal Revenue Service Form W-8, or another applicable form or a
certificate of such Purchasing Lender or Participant indicating that no such
exemption or reduced rate is allowable with respect to such payments. Each
Purchasing Lender or Participant which delivers a Form W-8, W-9, 4224 or 1001
further undertakes to deliver to the Borrower and its Transferor Lender two
additional copies of such form (or a successor form) on or before the date that
such form expires or becomes obsolete or otherwise 



                                     - 87 -
<PAGE>   95

is required to be resubmitted as a condition to obtaining an exemption from
withholding tax or after the occurrence of any event requiring a change in the
most recent form so delivered by it, and such amendments thereto or extensions
or renewals thereof as may be reasonably required by the Borrower or its
Transferor Lender, either certifying that such Purchasing Lender or Participant
is entitled to receive payments under this Agreement and the Notes without
deduction or withholding of any United States Federal income taxes or is subject
to such tax at a reduced rate under an applicable tax treaty or stating that no
such exemption or reduced rate is allowable. The Borrower, in the case of a
Purchasing Lender or Transferor Lender in the case of a Participant shall be
entitled to withhold United States Federal income taxes at the full withholding
rate, unless the Purchasing Lender or Participant as the case may be establishes
an exemption, or at the applicable reduced rate, as established pursuant to this
provisions of this Section 10.05(d).

                           (e)      Assignments to Federal Reserve Bank. In 
addition to the assignments permitted above, any Lender may assign and pledge
all or any portion of its Loans and Notes to any Federal Reserve Bank as
collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve
Bank. No such assignment shall release the assigning Lender from its obligations
and duties hereunder or under the other Loan Documents.

                  10.06. Successors and Assigns. This Agreement shall be binding
upon the Borrower and the Agent, the Co-Agents, the Lenders, the L/C Issuer and
their respective successors and assigns, and shall inure to the benefit of the
Borrower, the Agent, the Co-Agents, the Lenders, the L/C Issuer and respective
successors and assigns; provided, however, that the Borrower shall not assign
its rights or duties hereunder or under any of the other Loan Documents without
the prior written consent of the Lenders.

                  10.07. No Implied Waivers; Cumulative Remedies; Writing
Required. No course of dealing and no delay or failure of the Agent, the
Co-Agents or any Lender in exercising any right, power, remedy or privilege
under this Agreement or any other Loan Document shall affect any other or future
exercise thereof or operate as a waiver thereof; nor shall any single or partial
exercise thereof or any abandonment or discontinuance of steps to enforce such a
right, power, remedy or privilege preclude any further exercise thereof or of
any other right, power, remedy or privilege. The rights and remedies of the
Agent, the Co-Agents and the Lenders under this Agreement and any other Loan
Documents are cumulative and not exclusive of any rights or remedies which they
would otherwise have. Any waiver, permit, consent or approval of any kind or
character on the part of any Lender of any breach or default under this
Agreement or any such waiver of any provision or condition of this Agreement
must be in writing and shall be effective only to the extent specifically set
forth in such writing.

                  10.08. Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or enforceability without
invalidating the remaining portions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.

                  10.09. Indemnity. The Borrower hereby agrees to indemnify the
Agent, the Co-Agents, the Lenders, the L/C Issuer, and the directors, officers,
employees, attorneys, agents and Affiliates or all of the foregoing (each of the
foregoing an "Indemnified Person") against, and hold each of them harmless from,
any loss, liabilities, damages, claims, costs and expenses (including reasonable
attorneys' fees and disbursements) suffered or incurred by any Indemnified
Person (except those caused by such Indemnified Person's gross negligence or
willful misconduct, ) arising out of, resulting from or in any manner connected
with, the execution, delivery and performance of each of the Loan Documents, the
Lender Obligations and any and all transactions related to or consummated in
connection with the Lender Obligations, including, without limitation, losses,
liabilities, damages, claims, costs and expenses suffered or incurred by any
Indemnified Person arising out of or related to investigating, preparing for,
defending against, or providing evidence, producing documents or taking any
other action in respect of any commenced or threatened litigation,
administrative proceeding or investigation under any Federal securities law or
by any Official Body of any jurisdiction, or at common law or otherwise, that is
alleged to arise out of or is based on (i) any untrue statement or alleged
untrue statement of any material fact of the Borrower or any Affiliate of the
Borrower in any document or schedule filed with the Securities and Exchange
Commission or any other Official Body, (ii) any omission or alleged omission to
state any material fact required to be stated in such document or schedule, or
necessary to make the statements made therein, in light of the circumstances
under which made, not misleading; (iii) any actual or alleged acts, practices or
omissions of the Borrower, any Subsidiary Guarantor, or any of their respective
directors, officers, partners, employees, attorneys, agents or Affiliates,
related to the making of any acquisition, purchase of shares or assets pursuant
thereto, financing of such purchases or the consummation of any other
transactions contemplated by any such acquisitions that are alleged to be in
violation of any Federal securities law or of any other statute, regulation or
other law of any jurisdiction applicable to the making of any such acquisition,
the purchase of shares or assets pursuant thereto, the financing of such
purchases or the consummation of the other transactions contemplated by any such
acquisition; or (iv) any withdrawals, termination or cancellation of any such
proposed acquisition for any reason whatsoever. The indemnity set forth in this
Section 10.9 shall be in addition to any other obligations or liabilities of the
Borrower to the Agent, the Co-Agents, the Lenders or the L/C Issuer, or at
common law or otherwise. The provisions of this Section 10.9 shall survive the
payment of the Lender Obligations and the termination of this Agreement and the
other Loan Documents.

                  10.10 Confidentiality. The Agent, the Co-Agents, the Lenders
and the L/C Issuer shall keep confidential and not disclose to any Person, other
than to their respective directors, officers, employees, Affiliates and agents,
and to actual and potential Purchasing Lenders and Participants, all non-public
information concerning the Borrower and the Borrower's Affiliates which comes
into the possession of the Agent, the Co-Agents, the Lenders or the L/C Issuer
during the term hereof. Notwithstanding the foregoing, the Agent, the Co-Agents,
the Lenders and the L/C Issuer may disclose information concerning the Borrower
(i) in accordance-with normal banking practices and the Agent's, such
Co-Agent's, such Lender's or the L/C Issuer's policies concerning disclosure of
such information in connection with syndication or sales of Participations,
subject to informing the recipient of such information of the duties of
confidentiality hereunder, (ii) pursuant to what the Agent, 



                                     - 89 -
<PAGE>   97

such Co-Agent, such Lender or the L/C Issuer believes to be the lawful
requirements or request of any Official Body regulating banks or banking, (iii)
as required by governmental regulation or rule, judicial process or subpoena;
provided however, if permitted by law, the Agent, the Co-Agents, or such Lender
shall notify the Borrower and permit the Borrower, at the Borrower's cost, to
contest such subpoena; and (iv) to their respective attorneys, accountants and
auditors who have been informed of the confidentiality hereunder.

                  10.11. Survival. All representations, warranties, covenants
and agreements of the Borrower contained herein or in the other Loan Documents
or made in writing in connection herewith shall survive the issuance of the
Notes and the Letters of Credit and shall continue in full force and effect so
long as the Borrower may borrow hereunder and so long thereafter until payment
in full of all the Notes and the Lender Obligations is made. The obligations of
the Borrower under Sections 6.13, 10.02 and 10.03 shall survive the termination
of this Agreement and the discharge of the other obligations of the Borrower
hereunder, and any other Loan Documents, and shall also survive the payment in
full of all Lender Obligations, the termination of the Long-Term Revolving
Credit Commitment in accordance with the provisions of this Agreement and the
termination or expiration of all Letters of Credit in accordance with their
respective terms.

                  10.12. GOVERNING LAW. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
COMMONWEALTH OF PENNSYLVANIA, WITHOUT REGARD TO THE PRINCIPLES THEREOF REGARDING
CONFLICT OF LAWS, EXCEPTING APPLICABLE FEDERAL LAW AND EXCEPT ONLY TO THE EXTENT
PRECLUDED BY THE MANDATORY APPLICATION OF THE LAW OF ANOTHER JURISDICTION.

                  10.13. FORUM. THE PARTIES HERETO AGREE THAT ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE OTHER LOAN
DOCUMENTS TO WHICH THE BORROWER IS A PARTY MAY BE COMMENCED IN THE COURT OF
COMMON PLEAS OF ALLEGHENY COUNTY, PENNSYLVANIA OR IN THE DISTRICT COURT OF THE
UNITED STATES FOR THE WESTERN DISTRICT OF PENNSYLVANIA, AND THE PARTIES HERETO
AGREE THAT A SUMMONS AND COMPLAINT COMMENCING AN ACTION OR PROCEEDING IN EITHER
OF SUCH COURTS SHALL BE PROPERLY SERVED AND SHALL CONFER PERSONAL JURISDICTION
IF SERVED PERSONALLY OR BY CERTIFIED MAIL TO THE PARTIES AT THEIR ADDRESSES SET
FORTH IN SECTION 10.04, OR AS OTHERWISE PROVIDED UNDER THE LAWS OF THE
COMMONWEALTH OF PENNSYLVANIA. FURTHER, THE BORROWER HEREBY SPECIFICALLY CONSENTS
TO THE PERSONAL JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY,
PENNSYLVANIA AND THE DISTRICT COURT OF THE UNITED STATES FOR THE WESTERN
DISTRICT OF PENNSYLVANIA AND WAIVES AND HEREBY ACKNOWLEDGES THAT IT IS ESTOPPED
FROM RAISING ANY OBJECTION BASED ON FORUM NON CONVENIENS, ANY CLAIM THAT EITHER
SUCH COURT LACKS PROPER VENUE OR ANY OBJECTION THAT EITHER SUCH 



                                     - 90 -
<PAGE>   98

COURT LACKS PERSONAL JURISDICTION OVER THE BORROWER SO AS TO PROHIBIT EITHER
SUCH COURT FROM ADJUDICATING ANY ISSUES RAISED IN A COMPLAINT FILED WITH EITHER
SUCH COURT AGAINST THE BORROWER BY THE AGENT, THE CO-AGENTS, THE LENDERS OR THE
L/C ISSUER CONCERNING THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR PAYMENT TO
THE LENDERS. THE BORROWER HEREBY ACKNOWLEDGES AND AGREES THAT THE CHOICE OF
FORUM CONTAINED IN THIS SECTION 10.13 SHALL NOT BE DEEMED TO PRECLUDE THE
ENFORCEMENT OF ANY JUDGMENT OBTAINED IN ANY FORUM OR THE TAKING OF ANY ACTION
UNDER THE LOAN DOCUMENTS TO ENFORCE THE SAME IN ANY APPROPRIATE JURISDICTION.

                  10.14. Non-Business Days. Whenever any payment hereunder or
under the Notes is due and payable on a day which is not a Business Day, such
payment may be made on the next succeeding Business Day, and such extension of
time shall in each such case be included in computing interest in connection
with such payment.

                  10.15. Integration. This Agreement and the other Loan
Documents constitute the entire agreement between the parties relating to this
financing transaction and they supersede all prior understandings and
agreements, whether written or oral, between the parties hereto relating to the
transactions provided for herein.

                  10.16. Counterparts. This Agreement and any amendment hereto
may be executed in several counterparts and by each party on a separate
counterpart, each of which, when so executed and delivered, shall be an
original, but all of which together shall constitute but one and the same
instrument. In proving this Agreement, it shall not be necessary to produce or
account for more than one such counterpart signed by the other party against
whom enforcement is sought. Delivery of an executed counterpart of a signature
page to this Agreement by telecopier shall be as effective as delivery of a
manually executed counterpart of this Agreement.

                  10.17.   Funding by Branch, Subsidiary or Affiliate.

                           (a)      Notional Funding. Each Lender shall have 
the right from time to time, without notice to the Borrower, to deem any branch,
subsidiary or affiliate (which for the purposes of this Section 10.17 shall mean
any corporation or association which is directly or indirectly controlled by or
is under direct or indirect common control with any corporation or association
which directly or indirectly controls such Lender) of such Lender to have made,
maintained or funded any Revolving Credit Loan to which the Euro-Rate Option
applies at any time, provided that immediately following (on the assumption that
a payment were then due from the Borrower to such other office) and as a result
of such change the Borrower would not be under any greater financial obligation
to such Lender hereunder, pursuant to Section 2.08, 2.10, 2.11 or 2.12 hereof
than it would have been in the absence of such change. Notional funding offices
may be selected by each Lender without regard to a Lender's actual methods of
making, maintaining or funding the Revolving Credit Loans or any sources of
funding actually used by or available to such Lender.



                                     - 91 -
<PAGE>   99

                           (b)      Actual Funding. Each Lender shall have the 
right from time to time to make or maintain any Revolving Credit Loan by
arranging for a branch, subsidiary or affiliate of such Lender to make or
maintain such Revolving Credit Loan subject to the last sentence of this Section
10.17(b). If any Lender causes a branch, subsidiary or affiliate to make or
maintain any part of the Revolving Credit Loans hereunder, all terms and
conditions of this Agreement shall, except where the context clearly requires
otherwise, be applicable to such part of the Revolving Credit Loans to the same
extent as if such Revolving Credit Loans were made or maintained by such Lender
but in no event shall any Lender's use of such a branch, subsidiary or affiliate
to make or maintain any part of the Revolving Credit Loans hereunder cause such
Lender or such branch, subsidiary or affiliate to incur any cost or expenses
payable by the Borrower hereunder or require the Borrower to pay any other
compensation to any such Lender (including, without limitation, any expenses
incurred or payable pursuant to Section 2.08, 2.10, 2.11 or 2.12 hereof) which
would otherwise not be incurred.

                  10.18 WAIVER OF JURY TRIAL. THE BORROWER, EACH LENDER, THE
AGENT, THE CO-AGENTS AND THE L/C ISSUER EACH HEREBY WAIVES THE RIGHT TO TRIAL BY
JURY IN ANY COURT AND IN ANY ACTION OR PROCEEDING OF ANY TYPE IN WHICH THE
BORROWER, THE LENDERS, THE AGENT, THE CO-AGENTS, THE L/C ISSUER OR ANY OF THEIR
RESPECTIVE SUCCESSORS OR ASSIGNS IS A PARTY, AS TO ALL MATTERS AND THINGS
ARISING OUT OF THIS AGREEMENT, THE NOTES OR THE OTHER LOAN DOCUMENTS.
