                           SILICON VALLEY GROUP, INC.
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1. CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

The accompanying consolidated condensed financial statements have been prepared
by the Company without audit and reflect all adjustments, consisting only of
normal recurring adjustments, which in the opinion of management are necessary
to present fairly the financial position and the results of operations for the
interim periods. The statements have been prepared in accordance with the
regulations of the Securities and Exchange Commission, but omit certain
information and footnote disclosures necessary to present the statements in
accordance with generally accepted accounting principles. For further
information, refer to the Consolidated Financial Statements and Notes thereto
included in the Company's Annual Report on Form 10-K for the year ended
September 30, 1997. Results for fiscal 1998 interim periods are not necessarily
indicative of results to be expected for the fiscal year ending September 30,
1998.

2. RECLASSIFICATIONS

Certain reclassifications have been made to the prior year's Consolidated
Condensed Financial Statements to conform to the current fiscal period
presentation.

3.       INVENTORIES

         Inventories are comprised of:

4. NET INCOME (LOSS) PER SHARE

The Company adopted Statement of Financial Accounting Standards (SFAS) No. 128,
"Earnings Per Share," effective October 1, 1997, which replaces prior earnings
per share (EPS) reporting and requires dual presentation of basic and diluted
EPS. The Company has restated all prior periods to conform with this Statement.

Basic net income per share is computed by dividing net income by the weighted
average number of common shares outstanding.

The quarter ended June 30, 1998 was a loss period, therefore common stock
equivalents would be anti-dilutive and were not included in the calculation of
net loss per share. Diluted net income per share includes an additional 760,000
shares for the quarter ended June 30, 1997 to reflect the potential dilution
that could occur if dilutive stock options were converted into common stock.

5. TINSLEY LABORATORIES, INC. ACQUISITION

On November 26, 1997, the Company acquired Tinsley Laboratories, Inc. (TLI), in
a stock for stock transaction whereby approximately 1,091,000 shares of the
Company's Common Stock were exchanged for all outstanding shares of TLI Common
Stock. TLI designs, manufactures and sells precision optical components,
assemblies and systems to customers in a variety of industries and research
endeavors. The transaction was accounted for as a pooling of interests for
financial reporting purposes. All prior periods have been restated to include
TLI financial results.

6. LINE OF CREDIT

On June 30, 1998 the Company entered into an unsecured $150,000,000 bank
revolving line of credit agreement which expires in June, 2001. Advances under
the line of credit bear interest at either the U.S. prime rate or the LIBOR rate
plus 0.65% to 1.50%. The agreement includes covenants regarding liquidity,
profitability, leverage, coverage of certain charges and minimum net worth and
prohibits the payment of cash dividends.

7. REVENUE RECOGNITION

The Company recognizes revenue upon meeting the specifications under an
equipment purchase contract and when the buyer accepts and takes title to the
equipment, generally upon shipment. During the quarter ended June 30, 1998, the
Company recognized approximately $24 million of net sales to two customers who
accepted and took title to the related equipment, and agreed to normal payment
terms, but requested that the Company store the equipment until predetermined
shipment dates, which range through March 1999.

8. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income",
which establishes standards for the reporting and display of comprehensive
income and its components in a full set of general purpose financial statements;
and SFAS No. 131, "Disclosures About Segments of an Enterprise and Related
Information", which establishes annual and interim reporting standards for a
Company's business segments and related disclosures about its products,
services, geographic areas and major customers. Both SFAS No. 130 and SFAS No.
131 are effective for the Company beginning October 1, 1998. The Company
believes that the adoption of the new standards will not have a material effect
on the financial statements.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS




The information in this discussion contains forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934, as amended. Such statements are subject to
certain risks and uncertainties, including those discussed below, as well as
risk factors included in the Company's Annual Report on Form 10-K for the fiscal
year ended September 30, 1997, that could cause actual results to differ
materially from those projected. Readers are cautioned not to place undue
reliance on these forward-looking statements, which speak only as of the date
hereof. Forward-looking statements are indicated by an asterisk (*) following
the sentence in which such statement is made. The Company undertakes no
obligation to publicly release the results of any revisions to these
forward-looking statements which may be made to reflect events or circumstances
after the date hereof or to reflect the occurrence of unanticipated events.

RESULTS OF OPERATIONS

The Company designs, manufactures, markets and services semiconductor processing
equipment used in the fabrication of integrated circuits. The Company's products
are used in photolithography for exposure and photoresist processing, and in
deposition for oxidation/diffusion and low pressure chemical vapor deposition
(LPCVD). The Company manufactures and markets its photolithography exposure
products through its wholly owned subsidiary, SVG Lithography Systems, Inc.
(SVGL), its photoresist processing products through its Track Systems Division
(Track), its oxidation/diffusion and LPCVD products through its Thermco Systems
Division (Thermco), and certain of its precision optical components through its
wholly owned subsidiary Tinsley Laboratories, Inc.

On November 26, 1997, the Company acquired Tinsley Laboratories, Inc. ("TLI").
(See "Liquidity and Capital Resources.") The transaction has been accounted for
as a pooling of interests for financial reporting purposes. All amounts
discussed below have been retroactively restated to reflect the inclusion of
TLI, which does not have a material effect on the overall results of the
Company.

The semiconductor industry into which the Company sells its products is highly
cyclical and has, historically, experienced periodic downturns that have had a
severe effect on the semiconductor industry's demand for semiconductor
processing equipment. As a result of the Asian economic crisis, an oversupply of
certain semiconductor products, the impact of low cost personal computers, and
various other factors, semiconductor manufacturers have reduced planned
expenditures and cancelled or delayed the construction of new fabrication
facilities. This slowdown in demand began to impact the Company during the
fourth quarter of calendar 1997 (the Company's first fiscal quarter) as the
Company experienced lower customer bookings (bookings), customer deferrals of
scheduled equipment delivery dates and, to a lesser extent, customer order
cancellations. During the fourth quarter of fiscal 1997, the Company recorded
bookings of $205,711,000, significantly above bookings in fiscal 1998's first
three quarters of $175,253,000, $135,793,000 and $135,041,000, respectively. As
a result of the lower bookings, order rescheduling and cancellations, the
Company believes sales during the second half of fiscal 1998 will be as much as
35% to 40% below sales during the first half of fiscal 1998.* A 


                                       8

decrease in sales of this magnitude will result in significant reductions in the
Company's gross margin and net income.* There can be no assurance that the
Company will not experience further customer delivery deferrals, additional
order cancellations or a prolonged period of customer orders at reduced levels,
any or a combination of which would have a material adverse effect on the
Company's business and results of operations.*

In an effort to lessen the impact of these lower volumes, the Company reduced
its workforce by approximately 6% in the third quarter of 1998 and in July 1998
announced an additional reduction of approximately 21%. Additionally, the
Company shutdown the majority of its operations for five days during the third
quarter of fiscal 1998, has scheduled an additional ten shutdown days in the
fourth quarter of fiscal 1998 and has severely restricted personnel additions.*
The Company estimates that the operating results for the fourth quarter of
fiscal 1998 will include a charge of approximately $3,000,000 in severence and
other costs related to the reduction in its workforce discussed above.*

Historically, the Company has relied on a limited number of customers for a
substantial percentage of its net sales. In fiscal 1997, the Company's two
largest customers accounted for 60% of net sales, the largest representing 38%
of the total. During the first nine months of fiscal 1998, the Company's three
largest customers comprised 70% of net sales, the largest representing 39% of
the total. Further, the Company believes that, for the foreseeable future, it
will continue to rely on a limited number of major customers for a substantial
percentage of its net sales.* As a result of delays in delivering initial
quantities of 200-APS Track systems, the Company believes that one of its
largest Track customers will purchase systems with similar capabilities from
another supplier, which will have an adverse effect on Track's sales in future
periods.* See "Risks Inherent in the Company's Business - Rapid Technological
Change; Dependence on New Product Development". The loss of any other
significant customers, further delays in shipments due to rescheduling or
additional reductions in orders by a significant customer, including reductions
in orders due to market, economic or competitive conditions in the semiconductor
industry, will further exacerbate the adverse effect the customer order
rescheduling and cancellations discussed above have on the Company's business
and results of operations.*

During the quarter ended June 30, 1998, the Company recognized net sales of
approximately $24,000,000 to two customers who accepted and took title to the
related equipment and agreed to normal payment terms, but requested that the
Company store the equipment until predetermined shipment dates, which extend
through March 1999. The Company anticipates that it will receive similar
requests during the fourth quarter of fiscal 1998.

Net sales for the third fiscal quarter ended June 30, 1998 were $116,385,000,
down 41% from net sales for the preceding quarter of $195,872,000, and 30% below
third quarter fiscal 1997 net sales of $166,079,000. The decrease in third
quarter fiscal 1998 net sales compared to both the preceding and year-earlier
quarters was principally due to lower shipments by SVGL, Track and Thermco
resulting from lower customer order bookings during the first three quarters of
fiscal 1998, customer deferrals of scheduled equipment delivery dates and
customer order cancellations.

For the first nine months of fiscal 1998, the Company's net sales totaled
$500,964,000, approximately 14% above net sales of $439,982,000 for the first
nine months of fiscal 1997. The increased net sales were primarily due to
significantly higher SVGL and Track shipments during the first six months of
fiscal 1998, offset in part by the decreased third quarter fiscal 1998 shipments
discussed above.

During the third quarter of fiscal 1998, the Company recorded customer order
bookings of $135,041,000, approximately level with second quarter fiscal 1998
bookings of $135,793,000 but 

                                       9


<PAGE>   10

significantly below bookings for the year-earlier quarter of $188,396,000. The
Company includes in backlog only those orders to which a purchase order number
has been assigned by the customer, with all terms and conditions agreed upon and
for which delivery has been specified within twelve months. During the third
quarter of fiscal 1998, a customer order totaling $7,200,000 was removed from
the Company's backlog due to the customer deferring its scheduled delivery to a
date outside the Company's one-year parameter and $4,210,000 in other customer
orders were cancelled. After giving effect to such rescheduled and cancelled
orders, the Company's backlog at June 30, 1998 totaled $295,854,000,
significantly below the September 30, 1997 backlog of $435,482,000. At June 30,
1998, the backlog included orders for 40 Micrascan photolithography systems.
Additionally, SVGL had orders for 26 additional Micrascan systems with scheduled
delivery dates outside the twelve-month backlog window.

Gross margin was 32.7% in the third quarter of fiscal 1998, compared to 39.6%
during the preceding quarter and 37.8% in the third quarter of fiscal 1997. In
comparison to both the preceding and year-earlier quarters, the decreased gross
margin was primarily the result of lower overall volumes at SVGL and Track .

For the first nine months of fiscal 1998, gross margin was 37.9% compared to
37.7% for the first nine months of fiscal 1997. Improvements in gross margin
during the first six months of fiscal 1998 were substantially offset by the
decreased gross margin in the third quarter of fiscal 1998 discussed above.

Research, development and related engineering expenses are net of funding
received from outside parties under development agreements. Such funding is
typically payable upon the attainment of one or more development milestones that
are specified in the agreement. Neither the spending, nor the recognition of the
funding related to the development milestones is ratable over the term of the
agreements. For all the periods being compared, such funding was primarily
related to agreements between SVGL and certain customers for the development of
a 193 nanometer Micrascan system. (See "SVG Lithography Systems, Inc. (SVGL)").

Research, development and related engineering expenses (R&D) were $20,673,000
(18% of net sales) for the third quarter of fiscal 1998, $25,560,000 (13% of net
sales) for the preceding quarter and $18,261,000 (11% of net sales) for the
third quarter of fiscal 1997. For the third and second quarters of fiscal 1998
and the third quarter of fiscal 1997, development funding of $3,731,000,
$3,136,000 and $2,777,000, respectively, was recognized and offset against R&D.
The decrease in third quarter fiscal 1998 R&D from the preceding quarter was
primarily the result of reductions in costs related to certain development
programs. The increase in third quarter fiscal 1998 R&D over the year-earlier
quarter was primarily due to new product and process development, particularly
multiple lithography development programs, and the design and development of
equipment capable of processing the next generation 300mm wafer. Over both the
earlier quarters, the increase in third quarter fiscal 1998 R&D as a percentage
of net sales reflects the significantly lower level of shipments during the
current quarter.

For the first nine months of fiscal 1998 R&D was $67,302,000, up from
$53,210,000 for the same period of fiscal 1997. For the nine month periods ended
June 30, 1998 and 1997, funding received under joint development agreements of
$9,235,000 and $4,963,000, respectively, was offset against R&D expenditures.
Compared to the first nine months of fiscal 1997, the increase in R&D was
primarily due to new product and process development, particularly at SVGL, the
design and development of equipment capable of processing the next generation
300mm wafer and costs associated with Track's 200APS program.

Marketing, general and administrative expenses (MG&A) were $29,884,000 (26% of
net sales) for the third quarter of fiscal 1998 compared to $39,469,000 (20% of
net sales) for the preceding quarter and $37,136,000 (22% of net sales) for the
third quarter of fiscal 1997. The decrease in MG&A from the preceding quarter
was principally due to a reduction in certain shipment related costs. During the
year-earlier quarter, MG&A included a net charge of approximately $4,000,000
(the SMT Charge) related to an uncollectible receivable from Submicron
Technology PLC (SMT), a newly established semiconductor foundry in Thailand.
Compared to the year-earlier quarter, the decrease in MG&A is principally due to
the SMT Charge recorded in the earlier quarter and a reduction in certain
shipment related costs corresponding to the lower shipments during the quarter.

For the first nine months of fiscal 1998, marketing, general and administrative
expenses were $106,040,000 (21% of net sales) compared to $96,554,000 (22% of
net sales) for the first nine months of fiscal 1997. The year to year increase
in MG&A was primarily the result of costs related to the significantly increased
level of shipments during the first half of fiscal 1998 and, to a lesser degree,
additional administrative costs incurred in supporting the Company's operations.
These increases were offset in part by the effect of the SMT Charge recorded in
the year-earlier period.

Under the terms of a research and development agreement, SVGL owed IBM certain
royalties based on future operating results. In fulfillment of its obligation
under the agreement, during the second quarter of fiscal 1997 the Company
recognized an expense of $32,582,000 which represented royalties related to
products which were still under development at the settlement date.

For the third quarter of fiscal 1998, the Company had an operating loss of
$12,469,000, compared to operating income of $12,485,000 for the second quarter
of fiscal 1998 and operating income of $7,349,000 for the third quarter of
fiscal 1997. In comparison to the operating income in both of the earlier
quarters, the operating loss was the result of lower gross profits on
significantly lower net sales, offset in part by reduced operating expenses.

The Company had operating income of $16,648,000 for the first nine months of
fiscal 1998 compared to an operating loss of $16,292,000 for the corresponding
period of fiscal 1997. Without regard to the one-time royalty settlement with
IBM recorded during the first nine months of fiscal 1997, operating income was
approximately level from period to period.

Interest and other income was $1,339,000 during the third quarter of fiscal 1998
compared to $1,829,000 for the preceding quarter and $2,854,000 for the
year-earlier quarter. The decrease from the preceding quarter was due to lower
average cash balances available for investment and foreign currency translation
and exchange losses. The decrease in interest and other income from the
year-earlier quarter was due to lower average cash balances available for
investment, foreign currency translation and exchange losses and the absence of
certain royalty income under an agreement which expired during the fourth
quarter of fiscal 1997.

For the first nine months of fiscal 1998, interest and other income totaled
$4,650,000 compared to $8,256,000 for the first nine months of fiscal 1997. The
decrease from the year-earlier period was primarily the result of lower interest
income due to lower average cash balances available for investment, foreign
currency translation and exchange losses, in large part due to the strength of
the U.S. dollar, and the absence of certain royalty income under an agreement
which expired during the fourth quarter of fiscal 1997.

                                       11

Interest expense was $227,000 during the third quarter of fiscal 1998, compared
to $255,000 during the preceding quarter and $191,000 during the year-earlier
quarter. During the first nine months of fiscal 1998, interest expense was
$736,000, compared to $585,000 during the first nine months of fiscal 1997.

The Company recorded a 28% provision for income taxes for the first nine months
of fiscal 1998, compared to a 36% provision for all of fiscal 1997. Variations
in the Company's effective tax rate relate primarily to changes in the
geographic distribution of the Company's pretax income and certain tax free
interest income.

The minority interest represented that share of SVGL's operating results
attributable to its minority stockholder, IBM. In March 1997, the Company
purchased IBM's interest in SVGL for $3,000,000. The Company now accounts for
SVGL as a wholly owned subsidiary.

The Company had a net loss of $6,817,000 ($0.21 loss per share) for the third
quarter of fiscal 1998 compared to net income of $9,560,000 ($0.29 earnings per
share) for the second quarter of fiscal 1998 and net income of $6,562,000 ($0.20
earnings per share) for the third quarter of fiscal 1997. For the first nine
months of fiscal 1998, the Company had net income of $14,888,000 ($0.45 earnings
per share), compared to a net loss of $5,836,000 ($0.19 loss per share) for the
first nine months of fiscal 1997.

RISKS INHERENT IN THE COMPANY'S BUSINESS

Fluctuations in Quarterly Results. The Company has, at times during its
existence, experienced quarterly fluctuations in its operating results. Due to
the relatively small number of systems sold during each fiscal quarter and the
relatively high revenue per system, customer order rescheduling or
cancellations, or production or shipping delays can significantly effect
quarterly revenues and profitability. The Company has experienced, and may again
experience, quarters during which a substantial portion of the Company's net
sales are realized near the end of the quarter.* Accordingly, shipments
scheduled near the end of a quarter which are delayed for any reason can cause
quarterly net sales to fall short of anticipated levels. Since most of the
Company's expenses are fixed in the short term, such shortfalls in net sales
could have an adverse effect on the Company's business and results of
operations.* The Company's operating results may also vary from quarter to
quarter based upon numerous factors including the timing of new product
introductions, product mix, level of sales, the relative proportion of domestic
and international sales, activities of competitors, acquisitions, international
events, currency exchange fluctuations, and difficulties obtaining materials or
components on a timely basis.* In light of these factors, the Company may again
experience variability in its quarterly operating results.*

Rapid Technological Change; Dependence on New Product Development. Semiconductor
manufacturing equipment and processes are subject to rapid technological change.
The Company believes that its future success will depend upon its ability to
continue to enhance its existing products and their process capabilities and to
develop and manufacture new products with improved process capabilities that
enable semiconductor manufacturers to fabricate semiconductors more
efficiently.* The Company is developing Track and Lithography products, and has
begun shipping Thermco products, capable of processing 300mm wafers in
anticipation of the industry's transition to this larger wafer standard.*
Failure to successfully introduce these or any other new products in a timely
manner could result in the loss of competitive position and could reduce sales
of existing products.* In addition, new product introductions 

                                       12


<PAGE>   13

could contribute to quarterly fluctuations in operating results as orders for
new products commence and increase the potential for a decline in orders of
existing products, particularly if new products are delayed.*

From time-to-time, the Company has experienced delays in the introduction of its
products and product enhancements due to technical, manufacturing and other
difficulties and may experience similar delays in the future.* For example,
during fiscal 1996, the Company announced a new Track product, the 200-APS.
Initial shipments of the 200-APS were scheduled to commence during the second
quarter of fiscal 1997, but did not ship until the second quarter of fiscal
1998. There can be no assurance that the Company will not experience
manufacturing problems as a result of instability of the design of either the
hardware or software elements of this or other new technology, or be able to
efficiently manufacture the 200-APS or other new products.* These issues could
result in product delivery delays and a subsequent loss of future sales.*
Semiconductor manufacturers tend to select either a single supplier or a primary
supplier for a certain type of equipment. The Company believes that prolonged
delays in delivering initial quantities of newly developed products to multiple
customers, whether due to the protracted release of product from engineering
into manufacturing or due to manufacturing difficulties, could result in
semiconductor manufacturers electing to install competitive equipment in their
fabrication facilities and could preclude industry acceptance of the Company's
products.* The Company believes that the 200-APS delay will result in its
largest Track customer purchasing systems with similar capabilities from another
supplier, which will have an adverse effect on Track's sales in future periods.*
The Company's inability to effect the timely production of new products or any
failure of these products to achieve market acceptance could have a material
adverse effect on the Company's business and results of operations.*

Historically, the unit cost of the Company's products has been the highest when
they are newly introduced into production and cost reductions have come over
time through engineering improvements, economies of scale and improvements in
the manufacturing process.* As a result, new products have, at times, had an
unfavorable impact on the Company's gross margins and results of operations.
There can be no assurance that the initial shipments of new products will not
have an adverse effect on the Company's profitability or that the Company will
be able to attain design improvements, manufacturing efficiencies or
manufacturing process improvements over time.* Further, the potential
unfavorable effect of newly introduced products on profitability can be
exacerbated when there is intense price competition in the marketplace.*

Competition. The semiconductor equipment industry is intensely competitive. The
Company faces substantial competition both in the United States and other
countries in all of its products. Significant competitive factors include
technology and cost of ownership, a formula which includes such data as initial
price, system throughput and reliability and time to maintain or repair. Other
competitive factors include familiarity with particular manufacturers' products,
established relationships between suppliers and customers, product availability
and technological differentiation. Occasionally, the Company has encountered
intense price competition with respect to particular orders and has had
difficulty establishing new relationships with certain customers who have
long-standing relationships with other suppliers.

Many of the Company's competitors are Japanese corporations. As a result of the
recent strength of the U.S. dollar in relation to the Japanese yen, the Company
is at a disadvantage when competing on the basis of price. In light of the
recent economic downturn in certain Asian countries which represent significant
markets for such competitors, the Company believes that it may encounter more
severe price competition in its non-Asian markets.


                                       13

<PAGE>   14

Importance of the Japanese and Pacific Rim Markets. The Company's customers are
heavily concentrated in the United States and Europe. The Japanese and Pacific
Rim markets (including fabrication plants located in other parts of the world
which are operated by Japanese and Pacific Rim semiconductor manufacturers)
represent a substantial portion of the overall market for semiconductor
manufacturing equipment. To date, neither the Company's shipments into Japan nor
into the Pacific Rim have been significant. The Company believes that the
Japanese companies with which it competes have a competitive advantage because
their dominance of the Japanese and Pacific Rim semiconductor equipment market
provides them with the sales and technology base to compete more effectively
throughout the rest of the world. The Company is not engaged in any significant
collaborative effort with any Japanese or Pacific Rim semiconductor
manufacturers. As a result, the Company may be at a competitive disadvantage to
the Japanese equipment suppliers which are engaged in such collaborative efforts
with Japanese and Pacific Rim semiconductor manufacturers. The Company believes
that it must substantially increase its share of these markets if it is to
compete as a global supplier.* Further, in many instances, Japanese and Pacific
Rim semiconductor manufacturers fabricate devices such as dynamic random access
memory devices ("DRAMs"), with potentially different economic cycles than those
affecting the sales of devices manufactured by the majority of the Company's
U.S. and European customers. Failure to secure customers in these markets may
limit the global market share available to the Company and may increase the
Company's vulnerability to industry or geographic downturns.* Recent economic
difficulties in certain Asian countries, particularly Korea, will adversely
effect the Company's ability to penetrate such markets.*

In the past, several of the Company's larger customers have entered into joint
ventures ("JV") with European, Japanese or Pacific Rim semiconductor
manufacturers. In such cases, the Company has encountered intense price
competition from foreign competitors who are suppliers to the non-U.S. member of
the JV. Further, in certain instances the Company has not secured the equipment
order when the non-U.S. member has had the responsibility for selecting the
equipment to be used by the JV in its U.S. operations. There can be no assurance
that as the Company's customers form additional alliances, whether in the U.S.
or in other parts of the world, that the Company will be successful in obtaining
equipment orders or that it will be able to obtain orders with sufficient gross
margin to generate profitable transactions, either of which could have an
adverse effect on the Company's results of operations.*

Throughout the Pacific Rim, the Company is attempting to compete with major
equipment suppliers having significant market share and established service and
support infrastructures in place. Although the Company has invested in the
staffing and facilities that it believes are necessary to sell, service and
support customers, it anticipates that it will encounter significant price
competition as well as competition based on technological ability.* There can be
no assurance that the Company's Pacific Rim operations will be profitable, even
if it is successful in obtaining significant sales into this region.* Further,
due to recent economic issues in certain Asian countries, particularly Korea,
the Company's ability to penetrate such markets has been diminished. Failure to
secure customers in these markets would have an adverse effect on the Company's
business and results of operations.*

Year 2000. As the year 2000 approaches, a universal issue has emerged regarding
how existing application software programs and operating systems can accommodate
date values. The Company has completed a thorough analysis of the impact of
modifying its computer software for the year 2000. The Company believes that the
year 2000 modifications to the software necessary to effectively operate and
manage its business will be completed by the end of fiscal 1998.* Further, the
Company believes that the related costs of such solutions will not have a
material effect on its operating results.*



                                       14
<PAGE>   15

The Company is in the process of initiating formal communications with
significant suppliers and large customers to determine the extent to which the
Company is vulnerable if such parties fail to remediate their own Year 2000
issues. There can be no guarantee that such a failure would not have a material
adverse effect on the Company.

Business Interruption. The Company manufactures its Track products in San Jose,
California and substantially all of its Thermco products in Orange, California.
SVGL's photolithography exposure products are manufactured in Wilton and
Ridgefield, Connecticut. If the Company were to lose the use of one of its
facilities as a result of an earthquake, flood or other natural disaster, the
resultant interruptions in operations would have a material adverse effect on
the Company's results of operations and financial condition.* The Company's
California facilities are located in seismically active regions.

SVG Lithography Systems, Inc. (SVGL)

SVGL - Uncertain Market for Micrascan Products. The Company believes that the
photolithography exposure equipment market is one of the largest segments of the
semiconductor processing equipment industry.* To address this market, the
Company has invested and expects to continue to invest substantial resources in
SVGL's Micrascan technology and its family of Micrascan deep ultraviolet ("Deep
UV") step and scan photolithography systems, capable of producing line widths of
 .18 micron and below. The development of a market for the Company's Micrascan
step and scan photolithography products will be highly dependent on the
continued trend towards finer line widths in integrated circuits. Lithography
manufacturers have been successful in extending the capability of I-Line
steppers which have been utilized in the fabrication of complex semiconductor
devices with line widths of less than 0.5 micron, such as 64 megabit DRAMs. The
Company believes Deep UV lithography will be required to fabricate devices with
line widths below 0.3 micron.* Semiconductor manufacturers can purchase Deep UV
steppers to produce product at .25 micron line widths. However, the Company
believes that as devices increase in complexity and size and require finer line
widths, the technical advantages of Deep UV step and scan systems in the
exposure of critical layers, as compared to Deep UV steppers, will enable
semiconductor manufacturers to achieve finer line widths, higher yields and
superior critical dimension control.* The Company also believes that the
transition to Deep UV step and scan systems for the exposure of critical layers
will accelerate in calendar 1999 and that advanced semiconductor manufacturers
are beginning to require volume quantities of production equipment as advanced
as the current and pending versions of Micrascan.* Currently, competitive Deep
UV step and scan equipment capable of producing .25 micron line widths is
available in limited quantities from two competitors, and the Company believes
that at least one other manufacturer of advanced photolithography systems has
shipped at least one step and scan machine.* There can be no assurance that the
Company will be successful in competing with such systems.* Further, if
manufacturers of I-Line steppers and step and scan systems or manufacturers of
Deep UV steppers are able to further enhance existing technology to achieve
finer line widths sufficiently to erode the competitive and technological
advantages of Deep UV step and scan systems, demand for the Micrascan technology
may not develop as the Company expects.*

The Company believes that advanced logic devices and DRAMs will require
increasingly finer line widths.* Consequently, SVGL must continue to develop
advanced technology equipment capable of meeting its customers' current and
future requirements while offering those customers a progressively lower cost of
ownership.* In particular, the Company believes that it must continue its

SVGL - Need to Increase Manufacturing Capacity and System Output. The Company
believes that its ability to supply systems in volume will be a major factor in
customer decisions to commit to the Micrascan technology.* Based upon its
forecast of continued high growth in demand for photolithography equipment and
potential future demand for advanced lithography products, the Company has been
in the process of increasing SVGL's production capacity under an extremely
aggressive expansion schedule. In August 1996, as part of this expansion, the
Company purchased from The Perkin-Elmer Corporation a 243,000 square foot
facility occupied by SVGL in Wilton, Connecticut and an additional 201,000
square foot building, which SVGL now occupies, in Ridgefield, Connecticut.
Through the first half of fiscal 1998, the Company has invested in significant
capital improvements related to the buildings purchased and the equipment
required to expand the production capabilities of SVGL. While the Company
intends to continue certain of the expansion activities through the remainder of
fiscal 1998, it may not invest in all of the metrology and other equipment
required to maximize manufacturing capacity until industry demand recovers.*
However, the Company plans to continue its ramp of optical components, thus
enabling it to quickly respond to customer requirements. Once demand recovers,
the timely construction and equipping of facilities to successfully complete the
increase in capacity will require the continued recruitment, training and
retention of a high quality workforce, as well as the achievement of
satisfactory manufacturing results on a scale greater than SVGL has attempted in
the past. There can be no assurance that the Company can manage these efforts
successfully. Any failure to manage such efforts could result in product
delivery delays and a subsequent loss of future revenues. In particular, the
Company believes that protracted delays in delivering quantities of current and
future Micrascan products could result in semiconductor manufacturers electing
to install competitive equipment in their advanced fabrication facilities, which
could impede acceptance of the Micrascan products on an industry-wide basis. In
addition, the Company's operating results could also be adversely affected by
the increase in fixed costs and operating expenses related to increases in
production capacity if net sales, for any reason, do not increase
commensurately.

The time required to build a Micrascan system is significant. If SVGL is to be
successful in supplying increased quantities of Micrascan systems, it will not
only need to be able to build more systems, it will need to build them faster.*
SVGL will require additional trained personnel and additional raw materials and
components, as well as improved manufacturing and testing techniques to both
facilitate volume and shorten manufacturing cycle time.* To that end, SVGL is
continuing to develop its vendor supply infrastructure, and implement
manufacturing improvements.* Additionally, the Company believes that once
industry demand recovers, it must resume increasing its factory, field service
and technical support organization staffing and infrastructure to support the
anticipated customer requirements. There can be no assurance that the Company
will not experience manufacturing difficulties or encounter problems in its
attempt to increase production and upgrade or expand existing operations.*

One of the most critical components of the Micrascan systems is the projection
optics, which are primarily manufactured by SVGL. As part of its overall
investment in capacity, the Company has increased SVGL's optical manufacturing
floorspace. The Company believes that in order for SVGL to be a viable supplier
of advanced lithography systems in the future, it must successfully reduce the
cycle times required to build projection optics.*

On November 26, 1997, the Company acquired Tinsley Laboratories, Inc. ("TLI").
(See "Liquidity and Capital Resources".) A primary reason for the acquisition
was TLI's technology and expertise relating to aspherical lenses, a key
component of SVGL's photolithography products, the adaptation of certain of
TLI's manufacturing processes by SVGL and TLI's commencement of the fabrication
of non-aspherical lenses which are currently produced by SVGL.* There can be no
assurance that TLI's 


                                       16


<PAGE>   17

manufacturing technology is scaleable, or that such expertise can be transferred
without substantial time or expense, if at all.* The inability of SVGL to
transfer this production technology for use in processes of a substantially
larger scale or the inability of TLI to manufacture non-aspherical lenses for
SVGL in sufficient quantities to realize efficiencies of scale could adversely
effect the Company's ability to realize any significant benefits from the
acquisition of TLI.*

The Company believes that protracted delays in delivering quantities of both
current and future generations of Micrascan products to multiple customers could
result in semiconductor manufacturers electing to install competitive equipment
in their advanced fabrication facilities, and could preclude industry acceptance
of the Micrascan technology and products.* In addition, the Company's operating
results could also be adversely affected by the increase in fixed costs and
operating expenses related to increases in production capacity and field service
and technical support activities if net sales do not increase commensurately.*

SVGL - Sole Source Materials and Components. The raw material for a proprietary
component of the optical system for the Micrascan is available from only one
supplier. The supplier has expanded its capacity to meet SVGL's projected
requirements and has created and stored agreed upon quantities of safety stock.
Additionally, a version of the Company's Micrascan III photolithography system
utilizes an Excimer laser that is manufactured in volume by only one supplier,
which until the first quarter of fiscal 1998 was the only vendor the Company had
determined could meet its specifications. There can be no assurance that either
supplier will be able to supply the quantities of material required by SVGL.* If
either supplier was unable to meet its commitments, SVGL would be unable to
manufacture the quantity of systems required to meet the anticipated future
demand, which would have a material adverse effect on the Company's business and
results of operations.* SVGL has qualified an additional source of lasers for
its current and future versions of Micrascan systems, allowing the potential for
the integration of such lasers into its system configurations.*

Certain other components are obtained from single sources. Although the Company
has not experienced significant production delays due to unavailability or delay
in procurement of such component parts or raw materials to date, disruption or
termination of certain of these sources could occur and such disruptions could
have an adverse effect on the Company's business and could result in damage to
customer relationships.

SVGL - Research and Development Funding. Historically, the Company has depended
on external funding to assist in the high cost of development in its
photolithography operation. Beginning in fiscal 1996, the Company entered into
agreements with certain customers (the "Participants") whereby each agreed to
assist in funding the Company's development of an advanced technology 193
nanometer Micrascan system. In exchange for such funding, each Participant
received the right to purchase one such system and, in addition, received a
right of first refusal (ratable among such Participants) to all such machines
manufactured during the first two years following the initial system shipments.
For each initial system ordered, each Participant agreed to fund $5,000,000 in
such development costs. The agreements call for each Participant to pay
$1,000,000 of initial development funding and four subsequent payments of
$1,000,000 upon the completion of certain development milestones. The
Participants may withdraw from the development program without penalty, but
payments made against completed development milestones are not refundable and
all preferential rights to future equipment are forfeited. At June 30, 1998, the
Company had received $19,000,000 in funding from Participants, of which
$17,178,000 had been recognized and offset against research and development
expenditures. There can be no assurances that the Participants will remain in
the program.* In the event that the Company does not receive the funding


                                       17


<PAGE>   18

anticipated under the agreements, it would be required to replace the shortfall
from its own funds or other sources. If the Company were required to use its own
funds, its research and development expenses would increase and its operating
income would be reduced correspondingly. The agreements with the Participants
stipulate that if the Company receives funding for the development program in
excess of $25,000,000, it will issue, ratably to the Participants, credits
totaling such excess in the form of a cash discount which can be applied to the
purchase of additional systems by each Participant. There is no assurance that
the Company will receive all funding which it currently anticipates or that it
will be able to obtain future outside funding beyond that which it is currently
receiving.

SVGL - Market Penetration. The Company believes that for SVGL to succeed in the
long term, it must sell its Micrascan products on a global basis.* The Japanese
market (including fabrication plants operated outside Japan by Japanese
semiconductor manufacturers) and the Korean market represent a substantial
portion of the overall market for photolithography exposure equipment. To date,
the Company has not been successful penetrating either of these markets. Recent
economic difficulties in certain Asian economies, particularly Korea, may
adversely effect the Company's ability to penetrate such markets.*

SVGL - Future Profitability. If SVGL is to attain its objective of being a
volume supplier of advanced photolithography systems, the Company believes that
it must expand its customer base to include additional customers from whom it
secures and successfully fulfills orders for production-quantities of Micrascan
systems.* The Company believes that in light of the downturn in industry demand,
costs associated with the continued development of the Micrascan technology, the
expansion of SVGL's manufacturing capacity, the related increase in manpower and
customer support, and the potential difficulties inherent in manufacturing
sub-.25 micron Micrascan systems, in particular the projection optics required
for these systems, there can be no assurance that SVGL will be able to operate
profitably in the future.*

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1998, cash and cash equivalents and temporary investments totaled
$159,723,000, a decrease of $46,938,000 from the September 30, 1997 total of
$206,661,000. The decrease was primarily due to purchases of property and
equipment to facilitate the expansion of SVGL's manufacturing capacity and was
partially offset by cash generated from operating activities.

On November 26, 1997, the Company acquired Tinsley Laboratories, Inc. ("TLI") in
exchange for approximately 1,091,000 shares of the Company's Common Stock. TLI
designs, manufactures and sells precision optical components, assemblies and
systems to customers in a variety of industries and research endeavors. The
transaction was accounted for as a pooling of interests for financial reporting
purposes.

On June 30, 1998, the Company entered into an unsecured $150,000,000 bank
revolving line of credit agreement which expires June 30, 2001. Advances under
the line bear interest at the Prime Rate or 0.65% to 1.50% over LIBOR. The
agreement includes covenants regarding liquidity, profitability, leverage,
coverage of certain charges and minimum net worth and prohibits the payment of
cash dividends. At August 11, 1998, there were no borrowings outstanding under
the facility.

The Company believes that it has sufficient working capital and available bank
credit to sustain operations and provide for the expansion of its business for
the next twelve months.*

        may borrow, repay and reborrow Loans until the Maturity Date.

               (b) Notice of Borrowing. Borrower shall request each Borrowing by
        delivering to Agent an irrevocable written notice in the form of Exhibit

                      (ii) Whether the requested Borrowing is to consist of Base
               Rate Loans or LIBOR Loans;

        thereafter shall consist solely of Base Rate Loans. Borrower shall give

        before the date of the requested Borrowing in the case of a Borrowing
        consisting of LIBOR Loans and at least one (1) Business Day before the
        date of the requested Borrowing in the case of a Borrowing consisting of

        and of the amount and Type of (and, if applicable, the Interest Period

        Borrowing.

               (c) Loan Interest Rates. Borrower shall pay interest on the

               at a rate per annum equal to the Base Rate plus the Applicable
               Margin therefor, such rate to change from time to time as the
               Applicable Margin or Base Rate shall change; and

                      (ii) During such periods as such Loan is a LIBOR Loan, at
               a rate per annum equal at all times during each Interest Period

               shall change.

        All Loans in each Borrowing shall, at any given time prior to maturity,
        bear interest at one, and only one, of the above rates. The number of
        Borrowings consisting of LIBOR Loans shall not exceed ten (10) at any
        time.

               (d) Conversion of Loans. Borrower may convert any Borrowing from
        one Type of Borrowing to the other Type; provided, however, that any
        conversion of a Borrowing consisting of LIBOR Loans into a Borrowing
        consisting of Base Rate Loans shall be made on, and only on, the last
        day of an Interest Period for such LIBOR Loans. Borrower shall request
        such a conversion by an irrevocable written notice to Agent in the form
        of Exhibit B, appropriately completed (a "Notice of Conversion"), which
        specifies, among other things:

               on a day which is not a Business Day shall be extended to the
               next succeeding Business Day unless such next Business Day falls
               in another calendar month, in which case such Interest Period
               shall end on the immediately preceding Business Day; (B) any
               Interest Period which begins on the last Business Day of a
               calendar month (or on a day for which there is no numerically
               corresponding day in the calendar month at the end of such
               Interest Period) shall end on the last Business Day of a calendar
               month; and (C) no Interest Period shall end after the Maturity
               Date.

                      (ii) Borrower shall notify Agent by an irrevocable written
               notice in the form of Exhibit C, appropriately completed (a
               "Notice of Interest Period Selection"), at least three (3)
               Business Days prior to the last day of each Interest Period for a
               Borrowing consisting of LIBOR Loans of the Interest Period
               selected by Borrower for the next succeeding Interest Period for
               such LIBOR Loans. Each Notice of Interest Period Selection shall
               be given by first-class mail or facsimile to the office or the
               facsimile number and during the hours specified in Paragraph
               8.01; provided, however, that Borrower shall promptly deliver to
               Agent the original of any Notice of Interest Period Selection
               initially delivered by facsimile. If Borrower fails to notify
               Agent of the next Interest Period for a Borrowing consisting of
               LIBOR Loans in accordance with this Subparagraph 2.01(e), such
               LIBOR Loans shall automatically convert to Base Rate Loans on the
               last day of the current Interest Period therefor.

               (f) Scheduled Loan Payments. Borrower shall repay the principal
        amount of the Loans on the Maturity Date. Borrower shall pay accrued
        interest on the unpaid principal amount of each Loan in arrears (i) in
        the case of a Base Rate Loan, on the last day in each March, June,
        September and December, (ii) in the case of a LIBOR Loan, on the last
        day of each Interest Period therefor (and, if any such Interest Period
        is longer than three (3) months, every three (3) months); and (iii) in
        the case of all Loans, upon prepayment (to the extent thereof) and at
        maturity.

               (g) Purpose. Borrower shall use the proceeds of the Loans for
        Borrower's general corporate purposes, including working capital and
        acquisitions.

               (h) Maturity Date Extensions. On or before the last Business Day
        which is six (6) months prior to each anniversary date of this
        Agreement, Borrower may request the Lenders to extend the Maturity Date
        for an additional one-year period; provided, however, that Borrower may
        request such an extension only twice. Borrower shall request each such
        extension by appropriately completing, executing and delivering to Agent
        a written request in the form of Exhibit D (an " Extension Request").
        Borrower understands that this Subparagraph 2.01(h) is included in this
        Agreement for Borrower's convenience in requesting extensions and
        acknowledges that neither Agent nor any other Lender Party has promised
        (either expressly or implicitly), or has any obligation or commitment,
        to extend the Maturity Date at any time. Agent shall promptly deliver to
        each Lender three (3) copies of each Extension Request received by
        Agent. If a Lender, in its sole and absolute discretion, consents to any
        Extension Request, such Lender shall evidence such consent by executing
        and returning two (2) copies of the Extension Request to Agent not later
        than the last Business Day which is five (5) months prior to the
        Maturity Date. Any failure by any Lender so to execute and return an
        Extension Request shall be deemed a denial thereof. If Borrower delivers
        an Extension Request to Agent pursuant to the first sentence of this
        Subparagraph 2.01(h), then not later than the last Business Day which is
        four (4) months days prior to the Maturity Date, Agent shall notify
        Borrower in writing whether (i) Agent has received a copy of the
        Extension Request executed by each Lender, in which case the definition
        of "Maturity Date" set forth in Schedule 3.01 shall be deemed amended as
        provided in the Extension Request as of the date of such written notice
        from Agent to Borrower, or (ii) Agent has not received a copy of the
        Extension Request executed by each Lender, in which case such Extension
        Request shall be deemed denied. Agent shall deliver to Borrower, with
        each written notice under clause (i) of the preceding sentence which
        notifies Borrower that Agent has received a Extension Request executed
        by each Lender, a copy of the Extension Request so executed by each
        Lender.

        2.02. Letter of Credit Facility.

               (a) Letter of Credit Availability. Subject to the terms and
        conditions of this Agreement (including the amount limitations set forth
        in Paragraph 2.03), ABN AMRO (in its capacity as the issuer of letters
        of credit under this Paragraph 2.02, "Issuing Bank") agrees to issue on
        behalf of Borrower from time to time during the period beginning on the
        Closing Date and ending on the date which is fifteen (15) days prior to
        the Maturity Date (the "LC Facility Expiration Date") such letters of
        credit as Borrower may request under this Paragraph 2.02 (individually,
        a "Letter of Credit"); provided, however, as follows:

                      (i) The aggregate amount available for drawing under all
               Letters of Credit at any time outstanding shall not the LC
               Commitment.

                      (ii) Each Letter of Credit shall be an irrevocable standby
               letter of credit that is either a Financial Standby Letter of
               Credit or a Performance Standby Letter of Credit.



                                       24
<PAGE>   29
                      (iii) Each Letter of Credit shall expire on or prior to
               the LC Facility Expiration Date.

                      (iv) Each Letter of Credit shall be governed by the
               Uniform Customs and Practices for Documentary Credits as most
               recently published by the International Chamber of Commerce (the
               "UCP") prior to the date of issuance of such Letter of Credit and
               the terms of the UCP are hereby incorporated by reference with
               respect to each Letter of Credit.

                      (v) Each Letter of Credit shall be in the minimum amount
               of $500,000.

                      (vi) Each Letter of Credit shall be in a form reasonably
               acceptable to Issuing Bank.

        Except as otherwise provided herein, Borrower may request Letters of
        Credit, cause or allow Letters of Credit to expire and request
        additional Letters of Credit until the LC Facility Expiration Date.

               (b) LC Application. Borrower shall request each Letter of Credit
        by delivering to Agent and Issuing Bank an irrevocable written
        application in a form reasonably acceptable to Issuing Bank,
        appropriately completed (an "LC Application"), which specifies, among
        other things:

                      (i) The stated amount of the requested Letter of Credit;

                      (ii) The name and address of the beneficiary of the
               requested Letter of Credit;

                      (iii) The expiration date of the requested Letter of
               Credit;

                      (iv) The documentary conditions for drawing under the
               requested Letter of Credit; and

                      (v) The date of issuance for the requested Letter of
               Credit, which shall be a Business Day.

        Borrower shall give each LC Application to Issuing Bank at least five
        (5) Business Days before the proposed date of issuance of the requested
        Letter of Credit. Each LC Application shall be delivered by first-class
        mail or facsimile to Agent and Issuing Bank at their respective offices
        or facsimile numbers and during the hours specified in Paragraph 8.01;
        provided, however, that Borrower shall promptly deliver to Issuing Bank
        the original of any LC Application initially delivered by facsimile.
        Agent shall promptly notify each Lender of the contents of each LC
        Application. In the event of any conflict between the terms of this
        Agreement and the terms of any LC Application, the terms of this
        Agreement shall control.

               (c) Disbursement and Reimbursement.

                      (i) Disbursement. Issuing Bank shall notify Borrower upon
               receipt by Issuing Bank of the presentment of any demand for
               payment under any Letter of Credit, together with notice of the
               amount of such payment and the date such payment is to be made.
               Subject to the terms and provisions of such Letter of Credit,
               Issuing Bank shall make such payment (a "Drawing Payment") to the
               appropriate beneficiary.

                      (ii) Time of Reimbursement. Not later than 11:00 a.m. on
               the day each Drawing Payment is to be made by Issuing Bank (if
               Borrower received notice from Issuing Bank pursuant to clause (i)
               of Subparagraph 2.02(c) prior to 9:00 a.m. on such day, or not
               later than 11:00 a.m. on the next Business Day if such notice is
               received after 9:00 a.m. on such day), Borrower shall make or
               cause to be made to Issuing Bank a payment in the amount of such
               Drawing Payment (a "Reimbursement Payment"); provided, however,
               that Borrower shall make such Reimbursement Payment to, or cause
               such Reimbursement Payment to be made to, Agent for the benefit
               of the Lenders if, prior to the time such Reimbursement
               Payment is made, Issuing Bank has notified Borrower that it has
               requested the Lenders pursuant to clause (ii) of Subparagraph
               2.02(d) to pay to Issuing Bank their respective Proportionate
               Shares of the Drawing Payment made by Issuing Bank. If any such
               Reimbursement Payment is made to Agent, Agent shall promptly pay
               to each Lender which has paid its Proportionate Share of the
               Drawing Payment, such Lender's Proportionate Share of the
               Reimbursement Payment and shall promptly pay to Issuing Bank the
               balance of such Reimbursement Payment.

                      (iii) Reimbursement Obligation Absolute. The obligation of
               Borrower to reimburse Issuing Bank or the Lenders, as the case
               may be, for Drawing Payments (such obligation to be referred to
               herein as a "Reimbursement Obligation") shall be absolute,
               unconditional and irrevocable, and shall be performed strictly in
               accordance with the terms of this Agreement under and without
               regard to any circumstances, including, without limitation (A)
               any lack of validity or enforceability of any of the Credit
               Documents, (B) the existence of any claim, setoff, defense or
               other right which 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 transferee may be
               acting), any Lender Party or any other Person, whether in
               connection with this Agreement, the transactions contemplated
               herein or in the other Credit Documents, or in any unrelated
               transaction, (C) any breach of contract or dispute between
               Borrower, any beneficiary or any transferee of any Letter of
               Credit (or any Persons for whom any such beneficiary or
               transferee may be acting), any Lender Party or any other Person,
               (D) any demand, statement or other document presented under any
               Letter of Credit proving to be forged, fraudulent, invalid or
               insufficient in any respect or any statement therein being untrue
               or inaccurate in any respect, (E) payment by Issuing Bank under
               any



                                       26
<PAGE>   31
               Letter of Credit against presentation of a demand for payment
               which does not comply (but which appears on its face to comply)
               with the terms of such Letter of Credit, (F) any non-application
               or misapplication by any beneficiary or any transferee of any
               Letter of Credit (or any Persons for whom any such beneficiary or
               transferee may be acting) of the proceeds of any drawing under
               such Letter of Credit or (G) any delay, extension of time,
               renewal, compromise or other indulgence or modification granted
               or agreed to by Issuing any Lender Party, with or without notice
               to or approval by Borrower, with respect to Borrower's
               indebtedness under this Agreement; provided, however, that this
               Subparagraph 2.02(c) shall not abrogate any right which Borrower
               may have to seek to enjoin any drawing under any Letter of Credit
               or to recover damages from Issuing Bank pursuant to Subparagraph
               2.02(e).

               (d) Lender Participations; Loan Funding.

                      (i) Participation Agreement. Each Lender severally,
               unconditionally and irrevocably agrees with Issuing Bank to
               participate in the extension of credit arising from the issuance
               of each Letter of Credit in an amount equal to such Lender's
               Proportionate Share of the stated amount of such Letter of Credit
               from time to time, and the issuance of each Letter of Credit
               shall be deemed a confirmation by Issuing Bank of such
               participation in such amount.

                      (ii) Participation Funding. Issuing Bank may request the
               Lenders to fund their participations in Letters of Credit by
               paying to Issuing Bank all or any portion of any Drawing Payment
               made or to be made by Issuing Bank under any Letter of Credit.
               Issuing Bank shall make such a request by delivering to Agent
               (with a copy to Borrower), at any time after the drawing for
               which such payment is requested has been made upon Issuing Bank,
               a written request for such payment which specifies the amount of
               such Drawing Payment and the date on which such Drawing Payment
               is to be made or was made; provided, however, that Issuing Bank
               shall not request the Lenders to make any payment under this
               Subparagraph 2.02(d) in connection with any portion of a Drawing
               Payment for which Issuing Bank has been reimbursed from a
               Reimbursement Payment by Borrower unless such Reimbursement
               Payment has been thereafter recovered by Borrower. Agent shall
               promptly notify each Lender of the contents of each such request
               and of such Lender's Proportionate Share of the applicable
               portion of such Drawing Payment. Promptly following receipt of
               such notice from Agent, each Lender shall pay to Agent, for the
               benefit of Issuing Bank, such Lender's Proportionate Share of the
               applicable portion of such Drawing Payment.

                      (iii) Funding Through Loans. At any time any Reimbursement
               Obligations are outstanding, Agent may or, upon the written
               request of Issuing Bank (if Borrower is not then the subject of a
               bankruptcy proceeding), shall (subject to the terms and
               conditions of this Subparagraph 2.02(d)), initiate a Borrowing in
               an amount not exceeding the aggregate amount of such outstanding



                                       27
<PAGE>   32
               Reimbursement Obligations and use the proceeds of such Borrowing
               to repay all or a portion of such Reimbursement Obligations.
               Agent shall initiate such a Borrowing by delivering to each
               Lender (with a copy to Borrower) a written notice which specifies
               the aggregate amount of outstanding Reimbursement Obligations,
               the amount of the Borrowing (which initially shall consist of
               Base Rate Loans), the date of such Borrowing and the amount of
               the Loan to be made by such Lender as part of such Borrowing.
               Each Lender shall make available to Agent funds in the amount of
               its Loan as provided in Subparagraph 2.08(a). After receipt of
               such funds, Agent shall promptly disburse such funds to Issuing
               Bank and the Lenders, as appropriate, in payment of the
               outstanding Reimbursement Obligations.

                      (iv) Obligations Absolute. Each Lender's obligations to
               fund its participations under this Subparagraph 2.02(d) shall be
               absolute, unconditional and irrevocable and shall not be affected
               by (A) the occurrence or existence of any Default or Event of
               Default, (B) any failure to satisfy any condition set forth in
               Section III, (C) any event or condition which might have a
               Material Adverse Effect, (D) the failure of any other Lender to
               make any payment under this Subparagraph 2.02(d), (E) any right
               of offset, abatement, withholding or reduction which such Lender
               may have against Issuing Bank, Agent, any other Lender or
               Borrower, (F) any event, circumstance or condition set forth in
               Subparagraph 2.02(c) or Subparagraph 2.02(e), or (G) any other
               event, circumstance or condition whatsoever, whether or not
               similar to any of the foregoing; provided, however, that nothing
               in this Paragraph 2.02 shall prejudice any right which any Lender
               may have against Issuing Bank for any action by Issuing Bank
               which constitutes gross negligence or willful misconduct.

               (e) Liability of Issuing Bank, Etc. Borrower agrees that neither
        any Lender Party nor any of its respective directors, officers or
        employees shall be liable or responsible for (i) the use which may be
        made of any Letter of Credit or for any acts or omissions of any
        beneficiary or transferee thereof in connection therewith; (ii) any
        reference which may be made to this Agreement or to any Letter of Credit
        in any agreements, instruments or other documents relating to
        obligations secured by such Letter of Credit; (iii) the validity,
        sufficiency or genuineness of documents, or of any endorsement(s)
        thereon, even if such documents should in fact prove to be in any or all
        respects invalid, insufficient, fraudulent or forged or any statement
        therein prove to be untrue or inaccurate in any respect whatsoever; (iv)
        payment by Issuing Bank against presentation of documents which do not
        comply with the terms of any Letter of Credit, including failure of any
        documents to bear any reference or adequate reference to any Letter of
        Credit; or (v) any other circumstances whatsoever in making or failing
        to make payment under any Letter of Credit, except only that Issuing
        Bank shall be liable to Borrower for acts or events described in clauses
        (i) through (v) above, to the extent, but only to the extent, of any
        damages suffered by Borrower (excluding consequential damages) which
        Borrower proves were caused by (A) Issuing Bank's willful misconduct,
        bad faith or gross negligence in determining whether a drawing made
        under any Letter of



                                       28
<PAGE>   33
        Credit complies with the terms and conditions therefor stated in such
        Letter of Credit or (B) Issuing Bank's willful misconduct, bad faith or
        gross negligence in failing to pay under any Letter of Credit after a
        drawing by the beneficiary thereof strictly complying with the terms and
        conditions of such Letter of Credit. Without limiting the foregoing,
        Issuing Bank may accept a drawing that appears on its face to be in
        order, without responsibility for further investigation. The
        determination of whether a drawing has been made under any Letter of
        Credit prior to its expiration or whether a drawing made under any
        Letter of Credit is in proper and sufficient form shall be made by
        Issuing Bank in its sole discretion, which determination shall be
        conclusive and binding upon Borrower to the extent permitted by law.
        Borrower hereby waives any right to object to any payment made under any
        Letter of Credit with regard to a drawing that is in the form provided
        in such Letter of Credit but which varies with respect to punctuation,
        capitalization, spelling or similar matters of form (but not as to
        dollar amounts).

               (f) Reports of Issuing Bank. Issuing Bank shall, on a monthly
        basis if requested by Agent, provide to Agent such information regarding
        the Letters of Credit as Agent may reasonably request, including the
        Letters of Credit outstanding, the stated amounts of outstanding Letters
        of Credit, the expiration dates of outstanding Letters of Credit, the
        names of the beneficiaries of outstanding Letters of Credit, the amounts
        of unpaid Reimbursement Obligations and the amounts and times of Drawing
        Payments and Reimbursement Payments.

               (g) Purpose. Borrower shall use Letters of Credit for general
        corporate needs.

        2.03. Amount Limitations, Commitment Reductions, Etc.

               (a) Amount Limitation. The Outstanding Credit shall not at any
        time exceed the Total Commitment at such time. No Lender shall have any
        obligation to make the Loan to be made by it as part of any Borrowing
        and Issuing Bank shall have no obligation to issue any Letter of Credit
        if, after giving effect to such Borrowing or Letter of Credit, the
        Outstanding Credit would exceed the Total Commitment at such time.

               (b) Reduction or Cancellation of Commitments. Borrower may, upon
        five (5) Business Days written notice to Agent, permanently reduce the
        Total Commitment by the amount of Ten Million Dollars ($10,000,000) or
        an integral multiple of Five Million Dollars ($5,000,000) in excess
        thereof or cancel the Total Commitment in its entirety; provided,
        however, that:

                      (i) Borrower may not reduce the Total Commitment prior to
               the Maturity Date, if, after giving effect to such reduction, the
               Outstanding Credit would exceed the Total Commitment;

                      (ii) Borrower may not reduce the Total Commitment prior to
               the LC Facility Expiration Date, if, after giving effect to such
               reduction, the LC Commitment would exceed the Total Commitment;
               and



                                       29
<PAGE>   34
                      (iii) Borrower may not cancel the Total Commitment prior
               to the Maturity Date, if, after giving effect to such
               cancellation, any Loan, Letter of Credit or Reimbursement
               Obligation would then remain outstanding or the LC Commitment
               would remain in effect.

               (c) Effect of Commitment Reductions. From the effective date of
        any reduction of the Total Commitment, the Commitment Fees payable
        pursuant to Subparagraph 2.04(b) shall be computed on the basis of the
        Total Commitment as so reduced. Once reduced or cancelled, the Total
        Commitment may not be increased or reinstated without the prior written
        consent of all Lenders. Any reduction of the Total Commitment pursuant
        to Subparagraph 2.03(b) shall be applied ratably to reduce each Lender's
        Commitment in accordance with clause (i) of Subparagraph 2.09(a).

        2.04. Fees.

               (a) Agent's Fee. Borrower shall pay to Agent, for its own
        account, agent's fees and other compensation in the amounts and at the
        times set forth in the Agent's Fee Letter.

               (b) Commitment Fees. Borrower shall pay to Agent, for the ratable
        benefit of Lenders as provided in clause (iv) of Subparagraph 2.09(a),
        commitment fees (the "Commitment Fees") equal to the Commitment Fee Rate
        (as such rate changes from time to time) on the daily average Unused
        Commitment for the period beginning on the date of this Agreement and
        ending on the Maturity Date. Borrower shall pay the Commitment Fees in
        arrears on the last day in each March, June, September and December
        (commencing June 30, 1998) and on the Maturity Date (or if the Total
        Commitment is cancelled on a date prior to the Maturity Date, on such
        prior date).

               (c) Letter of Credit Fees.

                      (i) LC Usage Fees. Borrower shall pay to Agent, for the
               ratable benefit of the Lenders as provided in clause (vi) of
               Subparagraph 2.09(a), nonrefundable letter of credit fees for the
               Letters of Credit (the "LC Usage Fees") equal to the applicable
               LC Usage Fee Rate (as such rate changes from time to time) on the
               daily average available amount of each Letter of Credit for the
               period beginning on the date such Letter of Credit is issued and
               ending on the date such Letter of Credit expires. Borrower shall
               pay the LC Usage Fees quarterly in arrears on the last day in
               each March, June, September and December (commencing June 30,
               1998) and on the LC Facility Expiration Date.

                      (ii) LC Issuance Fees. Borrower shall pay to Agent, for
               the sole benefit of Issuing Bank, nonrefundable issuance fees for
               the Letters of Credit (the "LC Issuance Fees") equal to
               one-eighth of one percent (0.125%) per annum on the daily average
               available amount of each Letter of Credit for the period
               beginning on the date such Letter of Credit is issued and ending
               on the date such Letter of Credit expires. Borrower shall pay the
               LC Issuance Fees for each Letter



                                       30
<PAGE>   35
               of Credit in advance on the date of issuance of such Letter of
               Credit and on the date of any amendment to such Letter of Credit
               that increases its amount or extends its maturity.

                      (iii) Other Letter of Credit Fees. In addition to the LC
               Usage Fees and the LC Issuance Fees, Borrower shall pay to Agent,
               for the benefit of Issuing Bank, other standard fees of Issuing
               Bank for drawings under, transfers of and amendments to any
               Letter of Credit and other administrative actions performed by
               Issuing Bank in connection with any Letter of Credit, payable at
               such times and in such amounts as are consistent with Issuing
               Bank's standard fee policy at the time of such amendment or other
               action.

        2.05.

Prepayments.

               (a) Terms of all Prepayments. Upon the prepayment of any Loan
        (whether such prepayment is an optional prepayment under Subparagraph
        2.05(b), a mandatory prepayment required by Subparagraph 2.05(c) or a
        mandatory prepayment required by any other provision of this Agreement
        or the other Credit Documents, including a prepayment upon
        acceleration), Borrower shall pay to the Lender that made such Loan (i)
        all accrued interest to the date of such prepayment on the amount
        prepaid and (ii) if such prepayment is the prepayment of a LIBOR Loan on
        a day other than the last day of an Interest Period for such LIBOR Loan,
        all amounts payable to such Lender pursuant to Paragraph 2.12.

               (b) Optional Prepayments. At its option, Borrower may, upon one
        (1) Business Day notice to Agent in the case of Base Rate Loans or three
        (3) Business Days notice to Agent in the case of LIBOR Loans, prepay the
        Loans in any Borrowing in part, in an aggregate principal amount of
        $1,000,000 or more, or in whole.

               (c) Mandatory Prepayments. If, at any time, the Outstanding
        Credit exceeds the Total Commitment at such time, Borrower shall
        immediately prepay Loans in an aggregate principal amount equal to such
        excess.

        2.06. Other Payment Terms.

               (a) Place and Manner. Borrower shall make all payments due to
        each Lender Party hereunder by payments to Agent at Agent's office
        located at the address specified in Paragraph 8.01, with each payment
        due to a Lender to be for the account of such Lender and such Lender's
        Applicable Lending Office. Borrower shall make all payments hereunder in
        lawful money of the United States and in same day or immediately
        available funds not later than 11:00 a.m. on the date due. Agent shall
        promptly disburse to each Lender Party each payment received by Agent
        for the account of such Lender Party.

               (b) Date. Whenever any payment due hereunder shall fall due on a
        day other than a Business Day, such payment shall be made on the next
        succeeding Business Day, and such extension of time shall be included in
        the computation of interest or fees, as the case may be.

               (c) Late Payments. If any amount required to be paid by Borrower
        under this Agreement or the other Credit Documents (including principal
        or interest payable on any Loan, any fee or other amount payable to
        Agent or any Lender) remains unpaid after such amount is due, Borrower
        shall pay interest on the aggregate, outstanding balance of such amount
        from the date due until such amount is paid in full at a per annum rate
        equal to the Base Rate plus two percent (2.00%), such rate to change
        from time to time as the Base Rate shall change.

               (d) Application of Payments. All payments hereunder shall be
        applied first to unpaid fees, costs and expenses then due and payable
        under this Agreement or the other



                                       32
<PAGE>   37
        Credit Documents, second to accrued interest then due and payable under
        this Agreement or the other Credit Documents, third to any unpaid
        Reimbursement Obligations and finally to reduce the principal amount of
        outstanding Loans.

               (e) Failure to Pay Agent. Unless Agent shall have received notice
        from Borrower at least one (1) Business Day prior to the date on which
        any payment is due to Lenders hereunder that Borrower will not make such
        payment in full, Agent shall be entitled to assume that Borrower has
        made or will make such payment in full to Agent on such date and Agent
        may, in reliance upon such assumption, cause to be paid to Lenders on
        such due date an amount equal to the amount then due such Lenders. If
        and to the extent Borrower shall not have so made such payment in full
        to Agent, each such Lender shall repay to Agent forthwith on demand such
        amount distributed to such Lender together with interest thereon, for
        each day from the date such amount is distributed to such Lender until
        the date such Lender repays such amount to Agent, at a per annum rate
        equal to (i) the Federal Funds Rate for the first three (3) days and
        (ii) the rate applicable to Base Rate Loans thereafter. A certificate of
        Agent submitted to any Lender with respect to any amount owing by such
        Lender under this Subparagraph 2.06(e) shall constitute prima facie
        evidence of such amount.

        2.07. Loan Accounts; Notes.

               (a) Loan Accounts. The obligation of Borrower to repay the Loans
        made to it by each Lender and to pay interest thereon at the rates
        provided herein shall be evidenced by an account or accounts maintained
        by such Lender on its books (individually, a "Loan Account"), except
        that any Lender may request that its Loans be evidenced by a note or
        notes pursuant to Subparagraph 2.07(b). Each Lender shall record in its
        Loan Account (i) the date and amount of each Loan made by such Lender,
        (ii) the interest rates applicable to each such Loan and the effective
        dates of all changes thereto, (iii) the Interest Period for each LIBOR
        Loan, (iv) the date and amount of each principal and interest payment on
        each Loan and (v) such other information as such Lender may determine is
        necessary for the computation of principal and interest payable to it by
        Borrower hereunder; provided, however, that any failure by a Lender to
        make, or any error by any Lender in making, any such notation shall not
        affect Borrower's Obligations. The Loan Accounts shall constitute prima
        facie evidence of the matters noted therein.

               (b) Notes. If any Lender so requests, such Lender's Loans shall
        be evidenced by a promissory note in the form of Exhibit E
        (individually, a "Note") which note shall be (i) payable to the order of
        such Lender, (ii) in the amount of such Lender's Commitment, (iii) dated
        the Closing Date and (iv) otherwise appropriately completed. Borrower
        authorizes each Lender to record on the schedule annexed to such
        Lender's Note the date and amount of each Loan made by such Lender and
        of each payment or prepayment of principal thereon made by Borrower, and
        agrees that all such notations shall constitute prima facie evidence of
        the matters noted; provided, however, that any failure by a Lender to
        make, or any error by any Lender in making, any such notation shall not
        affect



                                       33
<PAGE>   38
        Borrower's Obligations. Borrower further authorizes each Lender to
        attach to and make a part of such Lender's Note continuations of the
        schedule attached thereto as necessary.

        2.08. Loan Funding.

               (a) Lender Funding and Disbursement to Borrower. Each Lender
        shall, before 11:00 a.m. on the date of each Borrowing, make available
        to Agent at Agent's office specified in Paragraph 8.01, in same day or
        immediately available funds, such Lender's Proportionate Share of such
        Borrowing. After Agent's receipt of such funds and upon satisfaction of
        the applicable conditions set forth in Section III, Agent shall promptly
        disburse such funds to Borrower in same day or immediately available
        funds. Agent shall disburse the proceeds of each Borrowing by
        disbursement to the account or accounts specified in the applicable
        Notice of Borrowing.

               (b) Lender Failure to Fund. Unless Agent shall have received
        notice from a Lender prior to the date of any Borrowing that such Lender
        will not make available to Agent such Lender's Proportionate Share of
        such Borrowing, Agent shall be entitled to assume that such Lender has
        made or will make such portion available to Agent on the date of such
        Borrowing in accordance with Subparagraph 2.08(a), and Agent may on such
        date, in reliance upon such assumption, disburse or otherwise credit to
        Borrower a corresponding amount. If any Lender does not make the amount
        of its Proportionate Share of any Borrowing available to Agent on or
        prior to the date of such Borrowing, such Lender shall pay to Agent, on
        demand, interest which shall accrue on such amount from the date of such
        Borrowing until such amount is paid to Agent at rates equal to (i) the
        daily Federal Funds Rate during the period from the date of such
        Borrowing through the third Business Day thereafter and (ii) the rate
        applicable to Base Rate Loans thereafter. A certificate of Agent
        submitted to any Lender with respect to any amount owing by such Lender
        under this Subparagraph 2.08(b) shall constitute prima facie evidence of
        such amount. If the amount of any Lender's Proportionate Share of any
        Borrowing is not paid to Agent by such Lender within three (3) Business
        Days after the date of such Borrowing, Borrower shall repay such amount
        to Agent, on demand, together with interest thereon, for each day from
        the date such amount was disbursed to Borrower until the date such
        amount is repaid to Agent, at the interest rate applicable at the time
        to the Loans comprising such Borrowing.

               (c) Lenders' Obligations Several. The failure of any Lender to
        make the Loan to be made by it as part of any Borrowing shall not
        relieve any other Lender of its obligation hereunder to make its Loan as
        part of such Borrowing, but no Lender shall be obligated in any way to
        make any Loan which another Lender has failed or refused to make or
        otherwise be in any way responsible for the failure or refusal of any
        other Lender to make any Loan required to be made by such other Lender
        on the date of any Borrowing.

        2.09. Pro rata Treatment.

               (a) Borrowings, Commitment Reductions, Etc. Except as otherwise
        provided herein:

                      (i) Each Borrowing, each reduction of the Total Commitment
               and participations in each Letter of Credit shall be made or
               shared among the Lenders pro rata according to their respective
               Proportionate Shares;

                      (ii) Each payment of principal on Loans in any Borrowing
               shall be shared among Lenders which made or funded the Loans in
               such Borrowing pro rata according to the respective unpaid
               principal amounts of such Loans then owed to such Lenders;

                      (iii) Each payment of interest on Loans in any Borrowing
               shall be shared among Lenders which made or funded the Loans in
               such Borrowing pro rata according to (A) the respective unpaid
               principal amounts of such Loans so made or funded by such Lenders
               and (B) the dates on which such Lenders so made or funded such
               Loans;

                      (iv) Each payment of Commitment Fees shall be shared among
               Lenders (excluding Defaulting Lenders) pro rata according to (A)
               their respective Proportionate Shares and (B) in the case of each
               Lender which becomes a Lender hereunder after the date hereof,
               the date upon which such Lender so became a Lender;

                      (v) Each Reimbursement Payment and interest payable by
               Borrower thereon shall be shared among the Lenders (including
               Issuing Bank) which made or funded the applicable Drawing Payment
               pro rata according to the respective amounts of such Drawing
               Payment so made or funded by such Lenders;

                      (vi) Each payment of LC Usage Fees shall be shared among
               the Lenders (including Issuing Bank in its capacity as a Lender
               but excluding Defaulting Lenders) pro rata according to (A) their
               respective Proportionate Shares and (B) in the case of each
               Lender which becomes a Lender hereunder after the date hereof,
               the date upon which such Lender so became a Lender;

                      (vii) Each payment of interest (other than interest on
               Loans) shall be shared among Lenders and Agent owed the amount
               upon which such interest accrues pro rata according to (A) the
               respective amounts so owed such Lenders and Agent and (B) the
               dates on which such amounts became owing to such Lenders and
               Agent; and

                      (viii) All other payments under this Agreement and the
               other Credit Documents shall be for the benefit of the Person or
               Persons specified.

               (b) Sharing of Payments, Etc. If any Lender shall obtain any
        payment (whether voluntary, involuntary, through the exercise of any
        right of setoff, or otherwise)



                                       35
<PAGE>   40

        on account of Loans owed to it in excess of its ratable share of
        payments on account of such Loans obtained by all Lenders entitled to
        such payments, such Lender shall forthwith purchase from the other
        Lenders such participations in the Loans as shall be necessary to cause
        such purchasing Lender to share the excess payment ratably with each of
        them; provided, however, that if all or any portion of such excess
        payment is thereafter recovered from such purchasing Lender, such
        purchase shall be rescinded and each other Lender shall repay to the
        purchasing Lender the purchase price to the extent of such recovery
        together with an amount equal to such other Lender's ratable share
        (according to the proportion of (i) the amount of such other Lender's
        required repayment to (ii) the total amount so recovered from the
        purchasing Lender) of any interest or other amount paid or payable by
        the purchasing Lender in respect of the total amount so recovered.
        Borrower agrees that any Lender so purchasing a participation from
        another Lender pursuant to this Subparagraph 2.09(b) may, to the fullest
        extent permitted by law, exercise all its rights of payment (including
        the right of setoff) with respect to such participation as fully as if
        such Lender were the direct creditor of Borrower in the amount of such
        participation.

        2.10. Change of Circumstances.

               (a) Inability to Determine Rates. If, on or before the first day
        of any Interest Period for any LIBOR Loan, (i) any Lender shall advise
        Agent that the LIBO Rate for such Interest Period cannot be adequately
        and reasonably determined due to the unavailability of funds in or other
        circumstances affecting the London interbank market or (ii) Required
        Lenders shall advise Agent that the rate of interest for such Loan does
        not adequately and fairly reflect the cost to such Lenders of making or
        maintaining such LIBOR Loan, Agent shall immediately give notice of such
        condition to Borrower and the other Lenders. After the giving of any
        such notice and until Agent shall otherwise notify Borrower that the
        circumstances giving rise to such condition no longer exist, Borrower's
        right to request the making of, conversion to or a new Interest Period
        for LIBOR Loans shall be suspended. Any LIBOR Loans outstanding at the
        commencement of any such suspension shall be converted at the end of the
        then current Interest Period for such LIBOR Loans into Base Rate Loans,
        unless such suspension has then ended.

               (b) Illegality. If, after the date of this Agreement, the
        adoption of any Governmental Rule, any change in any Governmental Rule
        or the application or requirements thereof (whether such change occurs
        in accordance with the terms of such Governmental Rule as enacted, as a
        result of amendment or otherwise), any change in the interpretation or
        administration of any Governmental Rule by any Governmental Authority,
        or compliance by any Lender with any request or directive (whether or
        not having the force of law) of any Governmental Authority (a "Change of
        Law") shall make it unlawful or impossible for any Lender to make or
        maintain any LIBOR Loan, such Lender shall immediately notify Agent and
        Borrower of such Change of Law. Upon receipt of such notice, (i)
        Borrower's right to request the making of, conversion to or a new
        Interest Period for LIBOR Loans shall be terminated, and (ii) Borrower
        shall, at the request of such Lender, either (A) pursuant to
        Subparagraph 2.01(d) convert any such then outstanding LIBOR Loans into
        Base Rate Loans at the end of the current Interest



                                       36
<PAGE>   41
        Period for such LIBOR Loans or (B) immediately repay or convert any such
        LIBOR Loans if such Lender shall notify Borrower that such Lender may
        not lawfully continue to fund and maintain such LIBOR Loans. Any
        conversion or prepayment of LIBOR Loans made pursuant to the preceding
        sentence prior to the last day of an Interest Period for such LIBOR
        Loans shall be deemed a prepayment thereof for purposes of Paragraph
        2.12. After any Lender notifies Agent and Borrower of such a Change of
        Law and until such Lender notifies Agent and Borrower that it is no
        longer unlawful or impossible for such Lender to make or maintain a
        LIBOR Loan, all Loans of such Lender shall be Base Rate Loans.

               (c) Increased Costs. If, after the date of this Agreement, any
        Change of Law:

                      (i) Shall subject any Lender to any tax, duty or other
               charge with respect to any LIBOR Loan, or shall change the basis
               of taxation of payments by Borrower to any Lender on such a LIBOR
               Loan or in respect to such a LIBOR Loan under this Agreement
               (except for changes in the rate of taxation on the overall net
               income of any Lender imposed by its jurisdiction of incorporation
               or the jurisdiction in which its principal executive office is
               located); or

                      (ii) Shall impose, modify or hold applicable any reserve
               (excluding any Reserve Requirement or other reserve to the extent
               included in the calculation of the LIBO Rate for any Loans),
               special deposit or similar requirement against assets held by,
               deposits or other liabilities in or for the account of, advances
               or loans by, or any other acquisition of funds by any Lender for
               any LIBOR Loan; or

                      (iii) Shall impose on any Lender any other condition
               related to any LIBOR Loan or Letter of Credit or such Lender's
               Commitments;

        And the effect of any of the foregoing is to increase the cost to such
        Lender of making, issuing, renewing, participating in or maintaining any
        such LIBOR Loan, Letter of Credit or its Commitments or to reduce any
        amount receivable by such Lender hereunder; then Borrower shall from
        time to time, within thirty (30) days after demand by such Lender, pay
        to such Lender additional amounts sufficient to reimburse such Lender
        for such increased costs or to compensate such Lender for such reduced
        amounts. A certificate setting forth in reasonable detail the amount of
        such increased costs or reduced amounts, submitted by such Lender to
        Borrower shall constitute prima facie evidence of such costs or amounts.
        The obligations of Borrower under this Subparagraph 2.10(c) shall
        survive the payment and performance of the Obligations and the
        termination of this Agreement.

               (d) Capital Requirements. If, after the date of this Agreement,
        any Lender determines that (i) any Change of Law affects the amount of
        capital required or expected to be maintained by such Lender or any
        Person controlling such Lender (a "Capital Adequacy Requirement") and
        (ii) the amount of capital maintained by such Lender or such Person
        which is attributable to or based upon the Loans, the Letters of Credit,
        the Commitments or this Agreement must be increased as a result of such
        Capital Adequacy Requirement (taking into account such Lender's or such
        Person's policies with respect to



                                       37
<PAGE>   42
        capital adequacy), Borrower shall pay to such Lender or such Person,
        within thirty (30) days after demand of such Lender, such amounts as
        such Lender or such Person shall determine are necessary to compensate
        such Lender or such Person for the increased costs to such Lender or
        such Person of such increased capital. A certificate setting forth in
        reasonable detail the amount of such increased costs, submitted by any
        Lender to Borrower shall constitute prima facie evidence of such costs.
        The obligations of Borrower under this Subparagraph 2.10(d) shall
        survive the payment and performance of the Obligations and the
        termination of this Agreement.

               (e) Mitigation. Any Lender which becomes aware of (i) any Change
        of Law which will make it unlawful or impossible for such Lender to make
        or maintain any LIBOR Loan or (ii) any Change of Law or other event or
        condition which will obligate Borrower to pay any amount pursuant to
        Subparagraph 2.10(c) or Subparagraph 2.10(d) shall notify Borrower and
        Agent thereof as promptly as practical. If any Lender has given notice
        of any such Change of Law or other event or condition and thereafter
        becomes aware that such Change of Law or other event or condition has
        ceased to exist, such Lender shall notify Borrower and Agent thereof as
        promptly as practical. Each Lender affected by any Change of Law which
        makes it unlawful or impossible for such Lender to make or maintain any
        LIBOR Loan or to which Borrower is obligated to pay any amount pursuant
        to Subparagraph 2.10(c) or Subparagraph 2.10(d) shall use reasonable
        commercial efforts (including changing the jurisdiction of its
        Applicable Lending Office) to avoid the effect of such Change of Law or
        to avoid or materially reduce any amounts which Borrower is obligated to
        pay pursuant to Subparagraph 2.10(c) or Subparagraph 2.10(d) if, in the
        reasonable opinion of such Lender, such efforts would not be
        disadvantageous to such Lender or contrary to such Lender's normal
        banking practices.

        2.11. Taxes on Payments.

               (a) Payments Free of Taxes. All payments made by Borrower under
        this Agreement and the other Credit Documents shall be made free and
        clear of, and without deduction or withholding for or on account of, any
        present or future income, stamp, documentary or other taxes, any duties,
        or any other levies, imposts, charges, fees, deductions or withholdings,
        now or hereafter imposed, levied, collected, withheld or assessed by any
        Governmental Authority (except net income taxes and franchise taxes in
        lieu of net income taxes imposed on any Lender Party by its jurisdiction
        of incorporation or the jurisdiction in which its Applicable Lending
        Office is located) (all such non- excluded taxes, duties, levies,
        imposts, charges, fees, deductions and withholdings being hereinafter
        called "Taxes"). If any Taxes are required to be withheld from any
        amounts payable to any Lender Party hereunder or under the other Credit
        Documents, the amounts so payable to Agent or such Lender shall be
        increased to the extent necessary to yield to Agent or such Lender
        (after payment of all Taxes) interest or any such other amounts payable
        hereunder at the rates or in the amounts specified in this Agreement and
        the other Credit Documents. Whenever any Taxes are payable by Borrower,
        as promptly as possible thereafter, Borrower shall send to Agent for its
        own account or for the account of



                                       38
<PAGE>   43

        such Lender, as the case may be, a certified copy of an original
        official receipt received by Borrower showing payment thereof. If
        Borrower fails to pay any Taxes when due to the appropriate taxing
        authority or fails to remit to Agent the required receipts or other
        required documentary evidence, Borrower shall indemnify Agent and
        Lenders for any taxes, interest or penalties that may become payable by
        any Lender Party as a result of any such failure. The obligations of
        Borrower under this Subparagraph 2.11(a) shall survive the payment and
        performance of the Obligations and the termination of this Agreement.

               (b) Withholding Exemption Certificates. On or prior to the date
        of the initial Borrowing or, if such date does not occur within thirty
        (30) days after the date of this Agreement, by the end of such 30-day
        period, each Lender which is not organized under the laws of the United
        States of America or a state thereof shall deliver to Borrower and Agent
        two duly completed copies of United States Internal Revenue Service Form
        1001 or 4224 (or successor applicable form), as the case may be,
        certifying in each case that such Lender is entitled to receive payments
        under this Agreement without deduction or withholding of any United
        States federal income taxes. Each such Lender further agrees (i)
        promptly to notify Borrower and Agent of any change of circumstances
        (including any change in any treaty, law or regulation) which would
        prevent such Lender from receiving payments hereunder without any
        deduction or withholding of such taxes and (ii) if such Lender has not
        so notified Borrower and Agent of any change of circumstances which
        would prevent such Lender from receiving payments hereunder without any
        deduction or withholding of taxes, then on or before the date that any
        certificate or other form delivered by such Lender under this
        Subparagraph 2.11(b) expires or becomes obsolete or after the occurrence
        of any event requiring a change in the most recent such certificate or
        form previously delivered by such Lender, to deliver to Borrower and
        Agent a new certificate or form, certifying that such Lender is entitled
        to receive payments under this Agreement without deduction or such
        taxes. If any Lender fails to provide to Borrower or Agent pursuant to
        this Subparagraph 2.11(b) (or, in the case of an Assignee Lender,
        Subparagraph 8.05(c)) any certificates or other evidence required by
        such provision to establish that such Lender is, at the time it becomes
        a Lender hereunder, entitled to receive payments under this Agreement
        without deduction or withholding of any United States federal income
        taxes, such Lender shall not be entitled to any indemnification under
        Subparagraph 2.11(a) for any Taxes imposed on such Lender primarily as a
        result of such failure.

               (c) Mitigation. If any Lender Party claims any additional amounts
        to be payable to it pursuant to this Paragraph 2.11, such Person shall
        use reasonable commercial efforts to file any certificate or document
        requested in writing by Borrower (including copies of Internal Revenue
        Service Form 1001 (or successor forms) reflecting a reduced rate of
        withholding or to change the jurisdiction of its Applicable Lending
        Office if the making of such a filing or such change in the jurisdiction
        of its Applicable Lending Office would avoid the need for or materially
        reduce the amount of any such additional amounts which may thereafter
        accrue and if, in the reasonable opinion of such Person, in the case of
        a change in the jurisdiction of its Applicable Lending Office, such



                                       39
<PAGE>   44

        change would not be disadvantageous to such Person or contrary to such
        Person's normal banking practices.

               (d) Tax Returns. Nothing contained in this Paragraph 2.11 shall
        require any Lender Party to make available any of its tax returns (or
        any other information relating to its taxes which it deems to be
        confidential).

     2.12. Funding Loss Indemnification. If Borrower shall (a) repay, prepay or
convert any LIBOR Loan on any day other than the last day of an Interest Period
therefor (whether a scheduled payment, an optional prepayment or conversion, a
mandatory prepayment or conversion, a payment upon acceleration or otherwise),
(b) fail to borrow any LIBOR Loan for which a Notice of Borrowing has been
delivered to Agent (whether as a result of the failure to satisfy any applicable
conditions or otherwise) or (c) fail to convert any Loans into LIBOR Loans in
accordance with a Notice of Conversion delivered to Agent (whether as a result
of the failure to satisfy any applicable conditions or otherwise), Borrower
shall, within five (5) Business Days after demand by any Lender, reimburse such
Lender for and hold such Lender harmless from all costs and losses actually
incurred by such Lender as a result of such repayment, prepayment, conversion or
failure. Borrower understands that such costs and losses may include, without
limitation, losses incurred by a Lender as a result of funding and other
contracts entered into by such Lender to fund a LIBOR Loan. Each Lender
demanding payment under this Paragraph 2.12 shall deliver to Borrower, with a
copy to Agent, a certificate setting forth the amount of costs and losses for
which demand is made, which certificate shall set forth in reasonable detail the
calculation of the amount demanded. Such a certificate so delivered to Borrower
shall constitute prima facie evidence of such costs and losses. The obligations
of Borrower under this Paragraph 2.12 shall survive the payment and performance
of the Obligations and the termination of this Agreement.

     2.13. Replacement of Lenders. If any Lender shall (a) become a Defaulting
Lender more than one (1) time in a period of twelve (12) consecutive months, (b)
continue as a Defaulting Lender for more than five (5) Business Days at any
time, (c) suspend its obligation to make or maintain LIBOR Loans pursuant to
Subparagraph 2.10(b) for a reason which is not applicable to any other Lender or
(d) demand any payment under Subparagraph 2.10(c), 2.10(d) or 2.11(a) for a
reason which is not applicable to any other Lender, then Agent may (or upon the
written request of Borrower, shall) replace such Lender (the "affected Lender"),
or cause such affected Lender to be replaced, with another lender (the
"replacement Lender") satisfying the requirements of an Assignee Lender under
Subparagraph 8.05(c), by having the affected Lender sell and assign all of its
rights and obligations under this Agreement and the other Credit Documents to
the replacement Lender pursuant to Subparagraph 8.05(c); provided, however, that
if Borrower seeks to exercise such right, it must do so within sixty (60) days
after it first knows or should have known of the occurrence of the event or
events giving rise to such right, and neither Agent nor any Lender shall have
any obligation to identify or locate a replacement Lender for Borrower. Upon
receipt by any affected Lender of a written notice from Agent stating that Agent
is exercising the replacement right set forth in this Paragraph 2.13, such
affected Lender shall sell and assign all of its rights and obligations under
this Agreement and the other Credit Documents to the replacement Lender pursuant
to an Assignment Agreement and



                                       40
<PAGE>   45
Subparagraph 8.05(c) for a purchase price equal to the sum of the principal
amount of the affected Lender's Loans so sold and assigned, all accrued and
unpaid interest thereon and its ratable share of all fees to which it is
entitled.

     2.14. Limitation on Collection of Costs . Notwithstanding anything to the
contrary contained herein, Borrower shall not be obligated to reimburse any
Lender for any cost or expense incurred by such Lender pursuant to Paragraph
2.10, Paragraph 2.11 or Paragraph 2.12 hereof unless demand for such payment is
made by Lender to Borrower within one (1) year after the date such cost or
expense was incurred.


SECTION III.    CONDITIONS PRECEDENT.

     3.01. Initial Conditions Precedent. The obligations of Lenders to make the
Loans comprising the initial Borrowing are subject to receipt by Agent, on or
prior to the Closing Date, of each item listed in Schedule 3.01, each in form
and substance satisfactory to Agent and each Lender, and with sufficient copies
for, Agent and each Lender.

Credit Event (including the initial Borrowing) is subject to the further
conditions that:

               (a) Borrower shall have delivered to Agent the Notice of
        Borrowing, Notice of Conversion, Notice of Interest Period Selection, LC
        Application or other applicable request, as the case may be, for such
        Credit Event in accordance with this Agreement; and

               (b) On the date such Credit Event is to occur and after giving
        effect to such Credit Event, the following shall be true and correct:

                      (i) The representations and warranties of Borrower and its
               Subsidiaries set forth in Paragraph 4.01 and in the other Credit
               Documents are true and correct in all material respects as if
               made on such date (except for representations and warranties
               expressly made as of a specified date, which shall be true as of
               such date);

                      (ii) No Default has occurred and is continuing or will
               result from such Credit Event; and

                      (iii) All of the Credit Documents are in full force and
               effect.

        The submission by Borrower to Agent of each Notice of Borrowing, each
        Notice of Conversion (other than a notice for a conversion to a Base
        Rate Loan), each Notice of Interest Period Selection, each LC
        Application and each other applicable request shall be deemed to be a
        representation and warranty by Borrower that each of the statements set
        forth above in this Subparagraph 3.03(b) is true and correct as of the
        date of such notice.




                                       41
<PAGE>   46

     3.03. Covenant to Deliver. Borrower agrees (not as a condition but as a
covenant) to deliver to Agent each item required to be delivered to Agent as a
condition to the occurrence of any Credit Event if such Credit Event occurs.
Borrower expressly agrees that the occurrence of any such Credit Event prior to
the receipt by Agent of any such item shall not constitute a waiver by any
Lender Party of Borrower's obligation to deliver such item.


SECTION IV.   REPRESENTATIONS AND WARRANTIES.

     4.01. Borrower's Representations and Warranties. In order to induce Agent
and Lenders to enter into this Agreement, Borrower hereby represents and
warranties to Agent and Lenders as follows:

               (a)    Due Incorporation, Qualification, etc.

                    (i) Borrower (A) is a corporation duly organized, validly
               existing and in good standing under the laws of its state of
               incorporation; (B) has the power and authority to own, lease and
               operate its properties and carry on its business as now
               conducted; and (C) is duly qualified, licensed to do business and
               in good standing as a foreign corporation in each jurisdiction
               where the failure to be so qualified or licensed is reasonably
               likely to have a Material Adverse Effect.

                      (ii) Each Material Subsidiary and, to the knowledge of
               Borrower, each other Subsidiary, (A) is a corporation duly
               organized, validly existing and in good standing under the laws
               of its state of incorporation; (B) has the power and authority to
               own, lease and operate its properties and carry on its business
               as now conducted; and (C) is duly qualified, licensed to do
               business and in good standing as a foreign corporation in each
               jurisdiction where the failure to be so qualified or licensed is
               reasonably likely to have a Material Adverse Effect.

               (b) Authority. The execution, delivery and performance by
        Borrower of each Credit Document executed, or to be executed, by
        Borrower and the consummation of the transactions contemplated thereby
        (i) are within the power of Borrower and (ii) have been duly authorized
        by all necessary actions on the part of Borrower.

               (c) Enforceability. Each Credit Document executed, or to be
        executed, by Borrower has been, or will be, duly executed and delivered
        by Borrower and constitutes, or will constitute, a legal, valid and
        binding obligation of Borrower, enforceable against Borrower in
        accordance with its terms, except as limited by bankruptcy, insolvency
        or other laws of general application relating to or affecting the
        enforcement of creditors' rights generally and general principles of
        equity.

               (d) Non-Contravention. The execution and delivery by Borrower of
        the Credit Documents executed by Borrower and the performance and
        consummation of the transactions contemplated thereby do not (i) violate
        any Requirement of Law applicable to Borrower; (ii) violate any
        provision of, or result in the breach or the acceleration of, or



                                       42
<PAGE>   47

        entitle any other Person to accelerate (whether after the giving of
        notice or lapse of time or both), any Contractual Obligation of
        Borrower; or (iii) result in the creation or imposition of any Lien (or
        the obligation to create or impose any Lien) upon any property, asset or
        revenue of Borrower (except such Liens as may be created in favor of the
        Lender Parties pursuant to this Agreement or the other Credit
        Documents).

               (e) Approvals. No consent, approval, order or authorization of,
        or registration, declaration or filing with, any Governmental Authority
        or other Person (including, without limitation, the shareholders of any
        Person) is required in connection with the execution and delivery of the
        Credit Documents executed by Borrower and the performance and
        consummation by Borrower of the transactions contemplated thereby,
        except such as have been made or obtained and are in full force and
        effect.

               (f) No Violation or Default. Neither Borrower, nor any of its
        Material Subsidiaries, nor to the best knowledge of Borrower any other
        Subsidiary, is in violation of or in default with respect to (i) any
        Requirement of Law applicable to such Person; (ii) any Contractual
        Obligation of such Person (nor is there any waiver in effect which, if
        not in effect, would result in such a violation or default), where, in
        each case, such violation or default is reasonably likely to have a
        Material Adverse Effect. Without limiting the generality of the
        foregoing, neither Borrower, nor any of its Material Subsidiaries, nor
        to the best knowledge of Borrower any other Subsidiary, (A) has violated
        any Environmental Laws, (B) has any liability under any Environmental
        Laws or (C) has received notice or other communication of an
        investigation or is under investigation by any Governmental Authority
        having authority to enforce Environmental Laws, where such violation,
        liability or investigation is reasonably likely to have a Material
        Adverse Effect. No Default has occurred and is continuing.

               (g) Litigation. No actions (including, without limitation,
        derivative actions), suits, proceedings or investigations are pending
        or, to the knowledge of Borrower, threatened against Borrower or any of
        its Subsidiaries at law or in equity in any court or before any other
        Governmental Authority which (i) is reasonably likely (alone or in the
        aggregate) to have a Material Adverse Effect or (ii) seeks to enjoin,
        either directly or indirectly, the execution, delivery or performance by
        Borrower of the Credit Documents or the transactions contemplated
        thereby.

               (h) Title; Possession Under Leases. Borrower and its Subsidiaries
        own and have good and marketable title, or a valid leasehold interest
        in, all their respective properties and assets as reflected in the most
        recent Financial Statements delivered to Agent (except those assets and
        properties disposed of in the ordinary course of business or otherwise
        in compliance with this Agreement since the date of such Financial
        Statements) and all respective assets and properties acquired by
        Borrower and its Subsidiaries since such date (except those disposed of
        in the ordinary course of business or otherwise in compliance with this
        Agreement). Such assets and properties are subject to no Lien, except
        for Permitted Liens. Each of Borrower and its Subsidiaries has complied
        with all material obligations under all material leases to which it is a
        party and



                                       43
<PAGE>   48
        all such leases are in full force and effect (except such leases that
        have expired in accordance with their terms or have been replaced by
        similar leases or where such failure to comply is not reasonably likely
        to have a Material Adverse Effect). Each of Borrower and its
        Subsidiaries enjoys peaceful and undisturbed possession under such
        leases.

               (i) Financial Statements. The Financial Statements of Borrower
        and its Subsidiaries which have been delivered to Agent, (i) are in
        accordance with the books and records of Borrower and its Subsidiaries,
        which have been maintained in accordance with good business practice;
        (ii) have been prepared in conformity with GAAP; and (iii) fairly
        present the financial conditions and results of operations of Borrower
        and its Subsidiaries as of the date thereof and for the period covered
        thereby. Neither Borrower nor any of its Subsidiaries has any Contingent
        Obligations, liability for taxes or other outstanding obligations which
        are material in the aggregate, except as disclosed in the audited
        Financial Statements dated September 30, 1997, furnished by Borrower to
        Agent prior to the date hereof, or in the Financial Statements delivered
        to Agent pursuant to clause (i) or (ii) of Subparagraph 5.01.

               (j) Equity Securities. To the knowledge of Borrower, all
        outstanding Equity Securities of Borrower are duly authorized, validly
        issued, fully paid and non-assessable.

               (k) No Agreements to Sell Assets; Etc. Except as otherwise
        permitted by Subparagraph 5.02(c) or Subparagraph 5.02(d), neither
        Borrower nor any of its Subsidiaries has any legal obligation, absolute
        or contingent, to any Person to sell the assets of Borrower or any of
        its Subsidiaries (other than sales in the ordinary course of business),
        or to effect any merger, consolidation or other reorganization of
        Borrower or any of its Subsidiaries or to enter into any agreement with
        respect thereto.

               (l)    Employee Benefit Plans.

                      (i) Based on the latest valuation of each Employee Benefit
               Plan that either Borrower or any ERISA Affiliate maintains or
               contributes to, or has any obligation under (which occurred
               within twelve months of the date of this representation), the
               aggregate benefit liabilities of such plan within the meaning of
               Section 4001 of ERISA did not exceed the aggregate value of the
               assets of such plan. Neither Borrower nor any ERISA Affiliate has
               any liability with respect to any post-retirement benefit under
               any Employee Benefit Plan which is a welfare plan (as defined in
               section 3(1) of ERISA), other than liability for health plan
               continuation coverage described in Part 6 of Title I(B) of ERISA,
               which liability for health plan contribution coverage is not
               reasonably likely to have a Material Adverse Effect.

                      (ii) Each Employee Benefit Plan complies, in both form and
               operation, in all material respects, with its terms, ERISA and
               the IRC, and no condition exists or event has occurred with
               respect to any such plan which would result in the incurrence by
               either Borrower or any ERISA Affiliate of any material liability,
               fine or penalty. Each Employee Benefit Plan, related trust
               agreement,



                                       44
<PAGE>   49

               arrangement and commitment of Borrower or any ERISA Affiliate is
               legally valid and binding and in full force and effect. No
               Employee Benefit Plan is being audited or investigated by any
               government agency or is subject to any pending or threatened
               claim or suit. Neither Borrower nor any ERISA Affiliate nor any
               fiduciary of any Employee Benefit Plan has engaged in a
               prohibited transaction under section 406 of ERISA or section 4975
               of the IRC.

                      (iii) Neither Borrower nor any ERISA Affiliate contributes
               to or has any material contingent obligations to any
               Multiemployer Plan. Neither Borrower nor any ERISA Affiliate has
               incurred any material liability (including secondary liability)
               to any Multiemployer Plan as a result of a complete or partial
               withdrawal from such Multiemployer Plan under Section 4201 of
               ERISA or as a result of a sale of assets described in Section
               4204 of ERISA. Neither Borrower nor any ERISA Affiliate has been
               notified that any Multiemployer Plan is in reorganization or
               insolvent under and within the meaning of Section 4241 or Section
               4245 of ERISA or that any Multiemployer Plan intends to terminate
               or has been terminated under Section 4041A of ERISA.

               (m) Other Regulations. Borrower is not subject to regulation
        under the Investment Company Act of 1940, the Public Utility Holding
        Company Act of 1935, the Federal Power Act, any state public utilities
        code or to any other Governmental Rule limiting its ability to incur
        indebtedness.

               (n) Patent and Other Rights. Borrower and its Subsidiaries own or
        license under validly existing agreements all patents, licenses,
        trademarks, trade names, trade secrets, service marks, copyrights and
        all rights with respect thereto, which are required to conduct their
        businesses as now conducted, except to the extent that failure to own or
        license the same could not reasonably be expected to have a Material
        Adverse Effect.

               (o) Governmental Charges and Other Indebtedness. Borrower and its
        Material Subsidiaries have filed or caused to be filed all tax returns
        which are required to be filed by them. Borrower and its Subsidiaries
        have paid, or made provision for the payment of, all taxes and other
        Governmental Charges which have or may have become due pursuant to said
        returns or otherwise and all other indebtedness, except such
        Governmental Charges or indebtedness, if any, which are being contested
        in good faith and as to which adequate reserves (determined in
        accordance with GAAP) have been provided or which are not reasonably
        likely to have a Material Adverse Effect if unpaid.

               (p) Margin Stock. Borrower owns no Margin Stock which, in the
        aggregate, would constitute a substantial part of the assets of
        Borrower, and no proceeds of any Loan will be used to purchase or carry,
        directly or indirectly, any Margin Stock or to extend credit, directly
        or indirectly, to any Person for the purpose of purchasing or carrying
        any Margin Stock.

               (q) Subsidiaries, etc. Set forth in Schedule 4.01(q) (as
        supplemented by Borrower from time to time in a written notice to Agent)
        is a complete list of all of



                                       45
<PAGE>   50

        Borrower's Subsidiaries, the jurisdiction of incorporation of each, the
        classes of Equity Securities of each and the number of shares and
        percentages of shares of each such class owned directly or indirectly by
        Borrower.

               (r) Catastrophic Events. Neither Borrower, nor any of its
        Material Subsidiaries, nor to the knowledge of Borrower any other
        Subsidiary, and none of their properties is or has been affected by any
        fire, explosion, accident, strike, lockout or other labor dispute,
        drought, storm, hail, earthquake, embargo, act of God or other casualty
        that is reasonably likely to have a Material Adverse Effect. There are
        no disputes presently subject to grievance procedure, arbitration or
        litigation under any of the collective bargaining agreements, employment
        contracts or employee welfare or incentive plans to which Borrower, any
        of its Material Subsidiaries, or to the knowledge of Borrower any of its
        Subsidiaries, is a party, and there are no strikes, lockouts, work
        stoppages or slowdowns, or, to the best knowledge of Borrower,
        jurisdictional disputes or organizing activities occurring or threatened
        which alone or in the aggregate are reasonably likely to have a Material
        Adverse Effect.

               (s) No Material Adverse Effect. No event has occurred and is
        continuing and no condition exists which is reasonably likely to have a
        Material Adverse Effect.

               (t) Chief Executive Office. Borrower's chief executive office is
        located at 101 Metro Drive, Suite 400, San Jose, CA 95110, or at such
        other location as Borrower may notify Agent from time to time in
        accordance with Subparagraph 5.01(g).

               (u) Accuracy of Information Furnished. None of the Credit
        Documents and none of the other certificates, statements or information
        furnished to any Lender Party by or on behalf of Borrower or any of its
        Subsidiaries in connection with the Credit Documents or the transactions
        contemplated thereby contains or will contain any untrue statement of a
        material fact or omits or will omit to state a material fact necessary
        to make the statements therein, in light of the circumstances under
        which they were made, not misleading.

        4.02. Reaffirmation. Borrower shall be deemed to have reaffirmed, for
the benefit of Lenders and Agent, each representation and warranty contained in
Paragraph 4.01 on and as of the date of each Credit Event (except for
representations and warranties expressly made as of a specified date, which
shall be true as of such date).

SECTION V.    COVENANTS.

        5.01. Affirmative Covenants. Until the termination of this Agreement and
the satisfaction in full by Borrower of all Obligations, Borrower will comply,
and will cause compliance, with the following affirmative covenants, unless
Required Lenders shall otherwise consent in writing:

               the examination necessary for their opinion they have reviewed

        correct entries will be made of their transactions in accordance with

               during normal business hours, to visit and inspect any of the
               properties and offices of Borrower and its Subsidiaries, to

               and make copies thereof and to discuss the affairs, finances and
               business of Borrower and its Subsidiaries with, and to be advised

                      (ii) If a Default or Event of Default then exists, at the
               expense of Borrower, Borrower and its Subsidiaries shall permit
               any Person designated by any Lender, to visit and inspect any of
               the properties and offices of Borrower and its Subsidiaries, to
               examine the books and records of Borrower and its Subsidiaries

                      (i) Carry and maintain insurance of the types and in the
               amounts customarily carried from time to time during the term of
               this Agreement by others engaged in substantially the same
               business as such Person and operating in the same geographic area
               as such Person, including, but not limited to, fire, public
               liability, property damage and worker's compensation;

                      (ii) Carry and maintain each policy for such insurance
               with financially sound insurers; and

                      (iii) Deliver to Agent from time to time, as Agent may

               effect.

               (e) Governmental Charges and Other Indebtedness. Borrower and its
        Material Subsidiaries shall promptly pay and discharge when due (i) all
        taxes and other Governmental Charges prior to the date upon which
        penalties accrue thereon, (ii) all indebtedness which, if unpaid, could
        become a Lien upon the property of Borrower or its Subsidiaries (other

otherwise provided under this Agreement, Agent shall take such action with
respect to the Credit Documents as shall be directed by the Required Lenders.

advice and statements of legal counsel, independent accountants and other
experts selected by Agent with reasonable care. As to any other matters not
expressly provided for by this Agreement, Agent shall not be required to take
any action or exercise any discretion, but shall be required to act or to
refrain from acting upon instructions of the Required Lenders and shall in all
cases be fully protected by Lenders in acting, or in refraining from acting,
hereunder or under any other Credit Document in accordance with the instructions
of the Required Lenders, and such instructions of the Required Lenders and any
action taken or failure to act pursuant thereto shall be binding on all of
Lenders.



                                       62

     7.03. Defaults. Agent shall not be deemed to have knowledge or notice of
the occurrence of any Default unless Agent has received a written notice from a
Lender or Borrower, referring to this Agreement, describing such Default and
stating that such notice is a "Notice of Default". If Agent receives such a
notice of the occurrence of a Default, Agent shall give prompt notice thereof to
Lenders. Agent shall take such action with respect to such Default as shall be
reasonably directed by the Required Lenders; provided, however, that until Agent
shall have received such directions, Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default as it shall deem advisable in the best interest of Lenders.

     7.04. Indemnification. Without limiting the Obligations of Borrower
hereunder, each Lender agrees to indemnify Agent, ratably in accordance with
their Proportionate Shares, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may at any time be imposed on, incurred
by or asserted against Agent in any way relating to or arising out of this
Agreement or any documents contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby or the enforcement of any of the
terms hereof or thereof; provided, however, that no Lender shall be liable for
any of the foregoing to the extent they arise from Agent's gross negligence or
willful misconduct. Agent shall be fully justified in refusing to take or in
continuing to take any action hereunder unless it shall first be indemnified to
its satisfaction by Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
obligations of each Lender under this Paragraph 7.04 shall survive the payment
and performance of the Obligations, the termination of this Agreement and any
Lender ceasing to be a party to this Agreement (with respect to events which
occurred prior to the time such Lender ceased to be a Lender hereunder).

     7.05. Non-Reliance. Each Lender represents that it has, independently and
without reliance on Agent, or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of the
business, prospects, management, financial condition and affairs of Borrower and
the Subsidiaries and its own decision to enter into this Agreement and agrees
that it will, independently and without reliance upon Agent or any other Lender,
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own appraisals and decisions in taking or not taking
action under this Agreement. Neither Agent nor any of its affiliates nor any of
their respective directors, officers, employees, agents or advisors shall (a) be
required to keep any Lender informed as to the performance or observance by
Borrower or any of its Subsidiaries of the obligations under this Agreement or
any other document referred to or provided for herein or to make inquiry of, or
to inspect the properties or books of Borrower or any of its Subsidiaries; (b)
have any duty or responsibility to provide any Lender with any credit or other
information concerning Borrower or any of its Subsidiaries which may come into
the possession of Agent, except for notices, reports and other documents and
information expressly required to be furnished to Lenders by Agent hereunder; or
(c) be responsible to any Lender for (i) any recital, statement, representation
or warranty made by Borrower or any officer, employee or agent of Borrower in
this Agreement or in any of the other Credit Documents, (ii) the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any Credit Document, (iii) the value or



                                       63
<PAGE>   68

sufficiency of any collateral or the validity or perfection of any of the liens
or security interests intended to be created by the Credit Documents, or (iv)
any failure by Borrower to perform its obligations under this Agreement or any
other Credit Document.

     7.06. Resignation or Removal of Agent. Agent may resign at any time by
giving thirty (30) days prior written notice thereof to Borrower and Lenders,
and Agent may be removed at any time with or without cause by the Required
Lenders. Upon any such resignation or removal, the Required Lenders shall have
the right to appoint a successor Agent, which Agent, if not a Lender, shall be
reasonably acceptable to Borrower; provided, however, that Borrower shall have
no right to approve a successor Agent if a Default has occurred and is
continuing. Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from the duties and obligations
thereafter arising hereunder. After any retiring Agent's resignation or removal
hereunder as Agent, the provisions of this Section VII shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as Agent.

     7.07. Authorization. Agent is hereby authorized by Lenders to execute,
deliver and perform, each of the Credit Documents to which Agent is or is
intended to be a party and each Lender agrees to be bound by all of the
agreements of Agent contained in the Credit Documents.

     7.08. Agent in its Individual Capacity. Agent and its affiliates may make
loans to, accept deposits from and generally engage in any kind of banking or
other business with Borrower and its Subsidiaries and affiliates as though Agent
were not Agent hereunder. With respect to Loans, if any, made by Agent in its
capacity as a Lender, Agent in its capacity as a Lender shall have the same
rights and powers under this Agreement and the other Credit Documents as any
other Lender and may exercise the same as though it were not Agent, and the
terms "Lender" or "Lenders" shall include Agent in its capacity as a Lender.


SECTION VIII.    MISCELLANEOUS.

     8.01. Notices. Except as otherwise provided herein, all notices, requests,
demands, consents, instructions or other communications to or upon Borrower or
any Lender Party Agent under this Agreement or the other Credit Documents shall

Agent, at its respective facsimile number or address set forth below or, if to
any Lender, at the address or facsimile number specified beneath the heading
"Address for Notices" under the name of such Lender in Part B of Schedule I (or
to such other facsimile number or address for any party as indicated in any
notice given by that party to the other parties). All such notices and
communications shall be effective (a) when sent by an overnight courier service

such service; (b) when mailed, first class postage prepaid and addressed as
aforesaid through the United States Postal Service, upon receipt; (c) when
delivered by hand, upon delivery; and (d) when faxed, upon confirmation of

Each Notice of Borrowing, Notice of Conversion, Notice of Interest Period
Selection and LC Application shall be given by Borrower to Agent's office
located at the address referred to above during Agent's normal business hours;
provided, however, that any such notice received by Agent after 11:00 a.m. on
any Business Day shall be deemed received by Agent on the next Business Day. In
any case where this Agreement authorizes notices, requests, demands or other
communications by Borrower to any Lender Party to be made by telephone or
facsimile, any Lender Party may conclusively presume that anyone purporting to
be a person designated in any incumbency certificate or other similar document
received by Agent or a Lender is such a person.

     8.02. Expenses. Borrower shall pay on demand, whether or not any Loan is
made hereunder, (a) all reasonable fees and expenses, including reasonable
attorneys' fees and expenses, incurred by Agent in connection with the
syndication of the facilities provided hereunder, the preparation, negotiation,
execution and delivery of, and the exercise of its duties under, this Agreement
and the other Credit Documents, and the preparation, negotiation, execution and
delivery of amendments and waivers hereunder and thereunder and (b) all
reasonable fees and expenses, including reasonable attorneys' fees and expenses,
incurred by and Lender Parties in the enforcement or attempted enforcement of
any of the Obligations or in preserving any of the Lender Parties' rights and
remedies (including, without limitation, all such fees and expenses incurred in
connection with any "workout" or restructuring affecting the Credit Documents or
the Obligations or any bankruptcy or similar proceeding involving Borrower or



                                       65
<PAGE>   70
any of its Subsidiaries). As used herein, the term "reasonable attorneys' fees
and expenses" shall include, without limitation, allocable costs and expenses of
Lender Parties' in-house legal counsel and staff. The obligations of Borrower
under this Paragraph 8.02 shall survive the payment and performance of the
Obligations and the termination of this Agreement.

     8.03. Indemnification. To the fullest extent permitted by law, Borrower
agrees to protect, indemnify, defend and hold harmless Lender Parties and their
Affiliates and their respective directors, officers, employees, agents and
advisors ("Indemnitees") from and against any and all liabilities, losses,
damages or expenses of any kind or nature and from any suits, claims or demands
(including in respect of or for reasonable attorney's fees and other expenses)
arising on account of or in connection with any matter or thing or action or
failure to act by Indemnitees, or any of them, arising out of or relating to the
Credit Documents or any transaction contemplated thereby, including without
limitation any use by Borrower of any proceeds of the Loans or any Letter of
Credit, except to the extent such liability arises from the willful misconduct
or gross negligence of such Indemnitee. Upon receiving knowledge of any suit,
claim or demand asserted by a third party that any Lender Party believes is
covered by this indemnity, such Lender Party shall give Borrower notice of the
matter and an opportunity to defend it, at Borrower's sole cost and expense,
with legal counsel reasonably satisfactory to such Lender Party; provided,
however, that Borrower shall not be responsible for the costs and expenses of
more than one such counsel (other than any local counsel and special counsel) in
any such action. Agent or such Lender may also require Borrower to defend the
matter. Any failure or delay of any Lender Party to notify Borrower of any such
suit, claim or demand shall not relieve Borrower of its obligations under this
Paragraph 8.03 but shall reduce such obligations to the extent of any increase
in those obligations caused solely by any such failure or delay which is
unreasonable. The obligations of Borrower under this Paragraph 8.03 shall
survive the payment and performance of the Obligations and the termination of
this Agreement.

     8.04. Waivers; Amendments. Any term, covenant, agreement or condition of
this Agreement or any other Credit Document may be amended or waived, and any
consent under this Agreement or any other Credit Document may be given, if such
amendment, waiver or consent is in writing and is signed by Borrower and the
Required Lenders (or Agent on behalf of the Required Lenders with the written
approval of the Required Lenders); provided, however that:

               (a) Any amendment, waiver or consent which would (i) increase the
        Total Commitment, (ii) extend the Maturity Date, (iii) reduce the
        principal of or interest on any Loan or any fees or other amounts
        payable for the account of Lenders hereunder, (iv) extend any scheduled
        principal, interest or fee payment date, (v) amend this Paragraph 8.04,
        or (vi) amend the definition of Required Lenders, must be in writing and
        signed or approved in writing by all Lenders;

               (b) Any amendment, waiver or consent which increases or decreases
        the Commitment of any Lender must be in writing and signed by such
        Lender;



                                       66
<PAGE>   71
               (c) Any amendment, waiver or consent which affects the rights or
        obligations of Agent must be in writing and signed by Agent; and

               (d) Any amendment, waiver or consent which increases the LC
        Commitment or otherwise affects the rights or obligations of Issuing
        Bank must be signed by Issuing Bank.

No failure or delay by any Lender Party in exercising any right under this
Agreement or any other Credit Document shall operate as a waiver thereof or of
any other right hereunder or thereunder nor shall any single or partial exercise
of any such right preclude any other further exercise thereof or of any other
right hereunder or thereunder. Unless otherwise specified in such waiver or
consent, a waiver or consent given hereunder shall be effective only in the
specific instance and for the specific purpose for which given.

     8.05. Successors and Assigns.

               (a) Binding Effect. This Agreement and the other Credit Documents
        shall be binding upon and inure to the benefit of Borrower, Lenders,
        Agent, all future holders of the Notes and their respective successors
        and permitted assigns, except that Borrower may not assign or transfer
        any of its rights or obligations under any Credit Document without the
        prior written consent of Agent and each Lender.

               (b) Participations. Any Lender may at any time sell to one or
        more banks or other financial institutions ("Participants")
        participating interests in any Loan owing to such Lender, any Note held
        by such Lender, any Commitment of such Lender or any other interest of
        such Lender under this Agreement and the other Credit Documents;
        provided, however, that no Lender may sell a participating interest in
        its Loans or Commitment in a principal amount of less than five million
        Dollars ($5,000,000). In the event of any such sale by a Lender of
        participating interests, such Lender's obligations under this Agreement
        shall remain unchanged, such Lender shall remain solely responsible for
        the performance thereof, such Lender shall remain the holder of its
        Notes for all purposes under this Agreement and Borrower and Agent shall
        continue to deal solely and directly with such Lender in connection with
        such Lender's rights and obligations under this Agreement. Any agreement
        pursuant to which any such sale is effected may require the selling
        Lender to obtain the consent of the Participant in order for such Lender
        to agree in writing to any amendment, waiver or consent of a type
        specified in clause (i), (ii), (iii) or (iv) of Subparagraph 8.04(a) but
        may not otherwise require the selling Lender to obtain the consent of
        such Participant to any other amendment, waiver or consent hereunder.
        Borrower also agrees that any Lender which has transferred any
        participating interest in its Commitment or Loans shall, notwithstanding
        any such transfer, be entitled to the full benefits accorded such Lender
        under Paragraph 2.10, Paragraph 2.11, and Paragraph 2.12, as if such
        Lender had not made such transfer.

               (c) Assignments. Any Lender may, at any time, sell and assign to
        any Lender or any Eligible Assignee (individually, an "Assignee Lender")
        all or a portion of its rights



                                       67
<PAGE>   72

        and obligations under this Agreement and the other Credit Documents
        (such a sale and assignment to be referred to herein as an "Assignment")
        pursuant to an assignment agreement in the form of Exhibit F (an
        "Assignment Agreement"), executed by each Assignee Lender and such
        assignor Lender (an "Assignor Lender") and delivered to Agent for its
        acceptance and recording in the Register; provided, however, that:

                      (i) Without the written consent of Agent, Issuing Bank
               and, if no Default has occurred and is continuing, Borrower
               (which consent of Agent, Issuing Bank and Borrower shall not be
               unreasonably withheld), no Lender may make any Assignment to any
               Assignee Lender which is not, immediately prior to such
               Assignment, a Lender hereunder or an Affiliate thereof; or

                      (ii) Without the written consent of Agent and, if no
               Default has occurred and is continuing, Borrower (which consent
               of Agent and Borrower shall not be unreasonably withheld), no
               Lender may make any Assignment to any Assignee Lender if, after
               giving effect to such Assignment, the Commitment of such Lender
               or such Assignee Lender would be less than Five Million Dollars
               ($5,000,000) (except that a Lender may make an Assignment which
               reduces its Commitment to zero without the written consent of
               Borrower and Agent) ; or

                      (iii) Without the written consent of Agent and, if no
               Default has occurred and is continuing, Borrower (which consent
               of Agent and Borrower shall not be unreasonably withheld), no
               Lender may make any Assignment which does not assign and delegate
               an equal pro rata interest in such Lender's Loans, Commitment and
               all other rights, duties and obligations of such Lender under
               this Agreement and the other Credit Documents.

        Upon such execution, delivery, acceptance and recording of each
        Assignment Agreement, from and after the Assignment Effective Date
        determined pursuant to such Assignment Agreement, (A) each Assignee
        Lender thereunder shall be a Lender hereunder with a Commitment as set
        forth on Attachment 1 to such Assignment Agreement (under the caption
        "Commitment After Assignment") and shall have the rights, duties and
        obligations of such a Lender under this Agreement and the other Credit
        Documents, and (B) the Assignor Lender thereunder shall be a Lender with
        a Commitment as set forth on Attachment 1 to such Assignment Agreement
        (under the caption "Commitment After Assignment"), or, if the Commitment
        of the Assignor Lender has been reduced to $0, the Assignor Lender shall
        cease to be a Lender and to have any obligation to make any Loan;
        provided, however, that any such Assignor Lender which ceases to be a
        Lender shall continue to be entitled to the benefits of any provision of
        this Agreement which by its terms survives the termination of this
        Agreement. Each Assignment Agreement shall be deemed to amend Schedule I
        to the extent, and only to the extent, necessary to reflect the addition
        of each Assignee Lender, the deletion of each Assignor Lender which
        reduces its Commitment to $0 and the resulting adjustment of Commitments
        arising from the purchase by each Assignee Lender of all or a portion of
        the rights and obligations of an Assignor Lender under this Agreement
        and the other Credit Documents. On or prior to



                                       68
<PAGE>   73

        the Assignment Effective Date determined pursuant to each Assignment
        Agreement, Borrower, at its own expense, shall execute and deliver to
        Agent, in exchange for the surrendered Note, if any, of the Assignor
        Lender thereunder, a new Note to the order of each Assignee Lender
        thereunder that requests such a note (with each new Note to be in an
        amount equal to the Commitment assumed by such Assignee Lender) and, if
        the Assignor Lender is continuing as a Lender hereunder, a new Note to
        the order of the Assignor Lender if so requested by such Assignor Lender
        (with the new Note to be in an amount equal to the Commitment retained
        by it). Each such new Note shall be dated the Closing Date and shall
        otherwise be in the form of the Note replaced thereby. The Note
        surrendered by the Assignor Lender shall be returned by Agent to
        Borrower marked "replaced". Each Assignee Lender which was not
        previously a Lender hereunder and which is not incorporated under the
        laws of the United States of America or a state thereof shall, within
        three (3) Business Days of becoming a Lender, deliver to Borrower and
        Agent two duly completed copies of United States Internal Revenue
        Service Form 1001 or 4224 (or successor applicable form), as the case
        may be, certifying in each case that such Lender is entitled to receive
        payments under this Agreement without deduction or withholding of any
        United States federal income taxes.

               (d) Register. Agent shall maintain at its address referred to in
        Paragraph 8.01 a copy of each Assignment Agreement delivered to it and a
        register (the "Register") for the recordation of the names and addresses
        of Lenders and the Commitments and Proportionate Shares of each Lender
        from time to time. The entries in the Register shall be conclusive in
        the absence of manifest error, and Borrower, Agent and Lenders may treat
        each Person whose name is recorded in the Register as the owner of the
        Loans recorded therein for all purposes of this Agreement. The Register
        shall be available for inspection by Borrower or any Lender at any
        reasonable time and from time to time upon reasonable prior notice.

               (e) Registration. Upon its receipt of an Assignment Agreement
        executed by an Assignor Lender and an Assignee Lender (and, to the
        extent required by Subparagraph 8.05(c), by Borrower and Agent) together
        with payment to Agent by Assignor Lender of a registration and
        processing fee of $3,000, Agent shall (i) promptly accept such
        Assignment Agreement and (ii) on the Assignment Effective Date
        determined pursuant thereto record the information contained therein in
        the Register and give notice of such acceptance and recordation to
        Lenders and Borrower. Agent may, from time to time at its election,
        prepare and deliver to Lenders and Borrower a revised Schedule I
        reflecting the names, addresses and respective Commitments and
        Proportionate Shares of all Lenders then parties hereto.

               (f) Confidentiality. Subject to Paragraph 8.10, Agent and Lenders
        may disclose the Credit Documents and any financial or other information
        relating to Borrower or any Subsidiary to each other or to any potential
        Participant or Assignee Lender.



                                       69
<PAGE>   74
               (g) Pledges to Federal Reserve Banks. Notwithstanding any other
        provision of this Agreement, any Lender may at any time assign all or a
        portion of its rights under this Agreement and the other Credit
        Documents to a Federal Reserve Bank. No such assignment shall relieve
        the assigning Lender from its obligations under this Agreement and the
        other Credit Documents.

     8.06. Setoff . In addition to any rights and remedies of Lenders provided
by law, each Lender shall have the right, with the prior consent of Agent but
without prior notice to or consent of Borrower, any such notice and consent
being expressly waived by Borrower to the extent permitted by applicable law,
upon the occurrence and during the continuance of an Event of Default, to
set-off and apply against the Obligations any amount owing from such Lender to
Borrower. The aforesaid right of set-off may be exercised by such Lender against
Borrower or against any trustee in bankruptcy, debtor in possession, assignee
for the benefit of creditors, receiver or execution, judgment or attachment
creditor of Borrower or against anyone else claiming through or against Borrower
or such trustee in bankruptcy, debtor in possession, assignee for the benefit of
creditors, receiver, or execution, judgment or attachment creditor,
notwithstanding the fact that such right of set-off may not have been exercised
by such Lender at any prior time. Each Lender agrees promptly to notify Borrower
after any such set-off and application made by such Lender, provided that the
failure to give such notice shall not affect the validity of such set-off and
application.

     8.07. No Third Party Rights. Nothing expressed in or to be implied from
this Agreement is intended to give, or shall be construed to give, any Person,
other than the parties hereto and their permitted successors and assigns
hereunder, any benefit or legal or equitable right, remedy or claim under or by

        Credit and Performance Letters of Credit will be set for each Pricing
        Period and will vary depending upon whether such period is a Level 1
        Period, a Level 2 Period, a Level 3 Period, a Level 4 Period or a Level
        5 Period.

2.      The first Pricing Period, which commences on the date of this Agreement
        and ends on June 30, 1998, will be a Level 2 Period.

3.      The second pricing period, which commences on July 1, 1998 and ends on
        September 30, 1998, will be a Level 1 Period, a Level 2 Period, a Level

        EBITDA and Senior Debt/EBITDA Ratio for the consecutive four-quarter
        period ending on March 30, 1998. (Borrower's EBITDA is a factor only in
        determining whether a Pricing Period will be a Level 1 Period or a Level
        2 Period when Borrower's Senior Debt/EBITDA is < 1.00.)
                                                       -

        four-quarter period ending on the last day of the fiscal quarter ending
        one quarter prior to the first day of such Pricing Period.
