                                     PART I

Item 1. BUSINESS

GENERAL

The Company designs, manufactures, markets and installs modular relocatable
classrooms and other modular buildings for commercial use. Based upon 1997 net
sales, the Company believes that it is the largest manufacturer of modular
relocatable classrooms in California. The Company's classrooms are sold
primarily to California school districts and to third parties and the State of
California principally for lease to California's school districts. The Company's
products include standardized classrooms, as well as customized structures for
use as libraries, gymnasiums, computer rooms and bathroom facilities. The
Company believes that its modular structures can be substituted for virtually
any part of a school. The Company's products are engineered and constructed in
accordance with structural and seismic safety specifications adopted by the
California Department of State Architects which regulates all school
construction on public land, standards which are more rigorous than the
requirements for other portable units.

As a result of net enrollment increases in California schools and budgetary
constraints experienced by the State of California which limited the
availability of funds for the addition of new classrooms over the last few years
prior to 1996, California's schools are reported to be among the most crowded in
the nation. As the State budget deficit has ameliorated, the legislature has
increased funding for new classrooms in an effort to reduce the average number
of students per class. State funding initiatives include funds from both (i) the
State's operating budget, such as the $200 million allocated for construction or
addition of classrooms out of the total of $822 million spent under the Class
Size Reduction Program for the 1996-1997 school year and the $1.5 billion
allocated for the 1997-1998 school year for both general operations and school
facilities, and (ii) the sale of statewide bond issues, such as the $9.2 billion
bond issue for school construction, including the addition of classrooms which
was approved in November 1998. See "Business -- Legislation and Funding."

These factors have combined to increase the demand for modular relocatable
classrooms, which cost significantly less and take much less time to construct
and install than conventional school facilities, and which permit a school
district to relocate the units as student enrollments shift. In addition, the
Company's products provide added flexibility to school districts in financing
the costs of adding classroom space, since modular relocatable classrooms are
considered personal property which can be financed out of a district's operating
budget in addition to its capital budget. In recognition of these advantages,
California legislation currently requires, with certain exceptions, that 20% of
all classroom space in the district, not just new space added, consists of
relocatable classrooms. See "Business -- Legislation and Funding."

SPI MERGER. On February 16, 1999, Modtech, Inc. ("Modtech" or the "Company") and
SPI Holdings, Inc., a Colorado corporation ("SPI") merged pursuant to the
Agreement and Plan of Reorganization and Merger, dated as of September 28, 1998
(the "Merger Agreement"), between Modtech and SPI. SPI is a designer,
manufacturer and wholesaler of commercial and light industrial modular
buildings. Pursuant to the Merger Agreement, SPI merged with a subsidiary of
Modtech Holdings, Inc. ("Holdings"), a newly formed Delaware corporation (the
"SPI Merger"). Concurrently, Modtech merged with a separate subsidiary of
Holdings (the "Modtech Merger"). Pursuant to the mergers, both SPI and Modtech
became wholly owned subsidiaries of Holdings. The SPI Merger will be accounted
for by the purchase method of accounting.

In connection with the SPI Merger, SPI stockholders received approximately $8
million in cash and approximately 4.3 million shares of Holdings Common Stock.
Holdings refinanced approximately $32 million of SPI debt. In connection with
the Modtech Merger, Modtech stockholders received approximately $40 million in
cash, approximately 8.3 million shares of Holdings Common Stock and 388,939
shares of Holdings Series A Preferred Stock. In connection with both mergers,
Holdings incurred a total of approximately $51 million of debt. See "Selected
Financial Data -- Unaudited Pro Forma Combined Financial Statements."

COASTAL ACQUISITION. On March 22, 1999, Holdings purchased 100% of the stock of
Coastal Modular Buildings, Inc. ("Coastal"). Coastal designs and manufactures
modular relocatable classrooms and other modular buildings for commercial use.
Coastal is based in St. Petersburg, Florida. The acquisition will be accounted
for by the purchase method of accounting.

INDUSTRY OVERVIEW

In recent years, the growth in population in California, both from births and
from immigration, has led to increasing school enrollments. As a result,
classrooms in many California school districts currently are reported to be
among the most crowded in the nation, with an average of 29 students per class
compared to a national average class size of 17. The California Department of
Finance has estimated that student enrollment in grades kindergarten through 12
will increase by approximately 18% over the period from 1995 through 2005.
Additionally, changes in population demographics have left many existing
permanent school facilities in older residential areas with excess capacity due
to declining enrollments, while many new residential areas are faced with a
continuing shortage of available classrooms. Consequently, it has become
necessary to add additional classrooms at many existing facilities, and to build
a number of new schools.


                                       2

<PAGE>   3

The construction of new schools and the addition of classrooms at existing
schools are tied to the sources and levels of funding available to California
school districts. The availability of funding for new school and classroom
additions, in turn, is determined in large measure by the amount of tax revenue
raised by the State, the level of annual allocations for education from the
State's budget which is determined by educational policies that are subject to
political concerns, and the willingness of the California electorate to approve
state and local bond issues to raise money for school facilities.

In 1978, California voters approved Proposition 13, which rolled back local
property taxes (a traditional source of funding for school districts) and
limited the ability of local school districts to raise taxes to finance the
construction of school facilities. The passage of Proposition 13, coupled with
growing student populations, has increased the need for local school districts
to find ways to reduce the cost of adding classrooms. The California legislature
has adopted several statutes designed to alleviate some of the problems
associated with the shortage of classrooms and lack of local funding
alternatives. For example, in 1976, California adopted legislation that through
November 1998 required, with certain exceptions, that at least 30% of all new
classroom space added using State funds must be relocatable structures. This
requirement was satisfied through the purchase or lease of the Company's
classrooms. See "Business -Legislation and Funding." Additionally, in 1979 the
California legislature adopted legislation that provides for State funding for
the purchase of relocatable classrooms that could be leased to local school
districts.

As the number of students enrolled in California schools continued to increase
throughout the 1990's, the State of California and California school districts
experienced increasing budget shortfalls. The resulting shortage of funding
available at both the State and local level led to declining sales of modular
relocatable classrooms, by the Company and on an industry-wide basis. However,
as the State budget deficit ameliorated, funding for modular relocatable
classrooms began to increase. This growth was accelerated when the California
Class Size Reduction Program was implemented in November 1996, the goal of which
is to reduce class sizes to 20 students in public elementary schools at the
kindergarten through third grade levels. For the 1996-1997 school year, the
State spent $822 million under this program, including $200 million specifically
for facilities, which may be relocatable classrooms. The total State funding
under the Class Size Reduction Program for the 1997-1998 school year was
approximately $1.5 billion for both general operations and school facilities.
See "Legislation and School Funding."

When compared to the construction of a conventionally built classroom, modular
classrooms offer a number of advantages, including, among others:

    Lower Cost                -- The cost of the Company's standard classroom 
                                 may be as low as $29,000 installed, as compared
                                 to $80,000 to $100,000 for conventional 
                                 construction of a comparable classroom;

    Shorter Construction      -- A modular classroom can be built and ready for
                                 occupancy in a shorter Time period of time than
                                 that required for state approval and 
                                 construction of a conventional facility;

    Flexibility of Use        -- Modular relocatable classrooms enable a
                                 school district to use the units for short or
                                 long term needs and to move them if necessary
                                 to meet shifts in student populations; and

    Ease of Financing         -- As personal rather than real property, modular
                                 classrooms may be leased on a long or 
                                 short-term basis from manufacturers and leasing
                                 companies. This allows school districts to
                                 finance modular classrooms out of both their
                                 operating and capital budgets.

MODULAR RELOCATABLE CLASSROOMS

The Company's modular relocatable classrooms are designed, engineered and
constructed in accordance with structural and seismic safety specifications
adopted by the California Department of State Architects, standards which are
more rigorous than the requirements for other portable units. The Department of
State Architects, which regulates all school construction on public land, has
prescribed extensive regulations regarding the design and construction of school
facilities, setting minimum qualifications for the preparation of plans and
specifications, and reviews all plans for the construction of material
modifications to any school building. Construction authorization is not given
unless the school district's architect certifies that a proposed project
satisfies construction cost and allowable area standards. The Company
subcontracts with structural engineering firms to interface with each school
district's architect or engineer to process project specifications through the
Department of State Architects. The Company believes that the regulated
environment in which the Company's classrooms are manufactured serves as a
significant barrier to market entry by prospective competitors. See "Business --
Competition."


                                       3
<PAGE>   4
Conventional school facilities constructed by school districts using funds from
the State Office of Public School Construction typically require two to three
years for approval and funding. By contrast, factory-built school buildings like
the Company's standard classrooms may be pre-approved by the State for use in
school construction. Once plans and specifications for a given classroom have
been pre-approved, school districts can thereafter include in their application
to obtain State funds for new facilities a notification that they intend to use
pre-approved, standardized factory-built classrooms. This procedure reduces the
time required in the State's approval process to as little as 90 days, thereby
providing an additional incentive to use factory-built relocatable classrooms.
In all cases, continuous on-site inspection by a licensed architect or
structural engineer is required during actual manufacture of the classrooms,
with the school district obligated to reimburse the Department for the costs of
such inspection.

The Company's classrooms are manufactured and installed in accordance with the
applicable Department of State Architects building code, which supersedes all
local building codes for purposes of school construction. The classrooms must
comply with accessibility requirements for the handicapped, seismic and fire
code requirements.

The Company manufactures and installs standard, largely pre-fabricated modular
relocatable classrooms, as well as customized classrooms, which are modular in
design, but assembled on-site using components manufactured by the Company
together with components purchased from third party suppliers. The Company's
classrooms vary in size from two modular units containing a total of 960 square
feet to 20 units that can be joined together to produce a facility comprising
9,600 square feet. Larger configurations are also possible. Typical prices for
the Company's standard classrooms range from $29,000 to $34,000, while prices
for a custom classroom generally exceed $50,000, depending upon the extent of
customization required.

The two basic structural designs for standard and custom modular classrooms are
a rigid frame structure and a shear wall structure. The rigid frame structure
uses a steel floor and roof system, supported at each corner with square steel
tubing. These buildings have curtain walls to enclose the interior from the
outside, and have the advantage of unlimited width and length. Rigid frame
structures may be used for multipurpose rooms and physical education buildings
as well as standard classrooms. Shear wall classrooms have a maximum width of 48
feet (four 12 foot modules) and a maximum length of 60 feet. These classrooms
use the exterior and interior walls to produce the required structural strength
and can be built at lower costs than rigid frame structures. The Company's most
popular factory-built classroom is a rigid frame design, with two modules
connected side by side to complete a 24 by 40 foot classroom.

Custom built classrooms, libraries and gymnasiums contain design variations and
dimensions such as ceiling height, pitch, overall size and interior
configuration. These units typically are not assembled at the factory but
instead are shipped in pieces, including floors, walls and roofs, and assembled
on-site. Contracts for custom built units may include the design, engineering
and layout for an entire school or an addition to a school, and involve site
preparation, grading, concrete and asphalt work and landscaping. Customized
classrooms are generally more expensive and take longer to complete than the
Company's standard classrooms.

The interior and exterior of all of the Company's modular classrooms can be
customized by employing different materials, design features and floor plans.
Most classrooms are open, but the interior of the buildings can be divided into
individual rooms by permanent or relocatable partitions. The floor covering is
usually carpet but may be linoleum or wood depending upon the intended use of
the classroom. Interior wall material is usually vinyl covered firtex over
gypsum board, while other finishes such as porcelain enamel or painted hardboard
may be used in such places as restrooms and laboratories. Electrical wiring, air
conditioning, windows, doors, fire sprinklers and plumbing are installed during
the manufacturing process. The exterior of the units is typically plywood
siding, painted to the customer's specifications, but other common siding
material may also be applied.

CLASSROOM CUSTOMERS

The Company markets and sells its modular classrooms primarily to California
school districts. The Company also sells its classrooms to the State of
California and leasing companies, both of which lease the classrooms principally
to California school districts. Sales of classrooms accounted for 94.2%, 98.1%
and 97.7% of the Company's total net sales for the years ended December 31,
1996, 1997 and 1998. The Company's customers typically pay cash from general
operating funds or the proceeds of local bond issues, or lease classrooms
through banks, leasing companies and other private funding sources. See
"Legislation and Funding."

Sales of classrooms to individual California school districts accounted for
approximately 74.5%, 71.1% and 72.5%, respectively, of the Company's net sales
during the years ended December 31, 1996, 1997 and 1998, with sales of
classrooms to third party lessors to California school districts during these
periods accounting for approximately 7.2%, 19.1% and 13.9%, respectively, of the
Company's net sales. The mix of school districts to which the Company sells its
products varies somewhat from year to year. Sales of classrooms directly to the
State of California during 1998 represented approximately 11.3% of the Company's
net sales for the period, compared to approximately 7.9% of the Company's 1997
net sales and approximately 12.5% of the Company's 1996 net sales. Sales of
classrooms to private schools, day care providers and out-of-state customers
accounted for less than one percent of the Company's net sales during the years
ended December 31, 1996, 1997 and 1998. One of the lessors to which the Company
sells classrooms for lease

                                       4
<PAGE>   5

to California school districts is affiliated with the Company through common
ownership by two of the Company's directors. During the years ended December 31,
1996, 1997 and 1998, sales of classrooms to this affiliated leasing company
comprised approximately 2.9%, 2.2% and 2.1%, respectively, of the Company's net
sales. See "Management -- Certain Transactions."

OTHER PRODUCTS

In addition to modular relocatable classrooms that are designed and manufactured
in accordance with the California Department of State Architects standards, the
Company also manufactures modular, portable buildings, which can be used as
office facilities and construction trailers and for other commercial purposes.
Currently, most of these non-classroom products are manufactured at the
Patterson, California plant, which the Company acquired in 1996. During the
years ended December 31, 1996, 1997 and 1998, sales of such modular, portable
buildings to commercial customers accounted, in the aggregate, for approximately
5.8%, 1.9% and 2.3%, respectively, of the Company's net sales. The Company also
manufactures a small number of modular structures that house and shelter
electronic equipment used in the wireless telecommunications industry. During
the years ended December 31, 1996, 1997 and 1998, sales of modular
telecommunications equipment shelters, which are included above in sales to
commercial customers, accounted for less than one percent of the Company's net
sales for each period.

SALES AND MARKETING

At December 31, 1998 the Company's classroom sales force was divided into three
marketing regions: Northern, Central and Southern California. At December 31,
1998 the Company employed three classroom salespersons, each of whom is
compensated on a commission basis. These salespersons maintain contact with the
individual school districts in their respective marketing regions on a quarterly
basis. They are also in contact with architects and building inspectors employed
by the school districts, as well as school officials who may be in a position to
influence purchasing decisions.

Most of the Company's contracts are awarded on an open bid basis. The marketing
process for many of the Company's contracts begins prior to the time the bid
process begins. After the Company selects bids or contracts that it desires to
pursue, the Company's marketing and engineering personnel interface directly
with various school boards, superintendents or architects during the process of
formulating bid or contract specifications. The Company prepares its bids or
proposals using various criteria, including current material prices, historical
overhead costs and a targeted profit margin. Substantially all of the Company's
contracts are turnkey, including engineering and design, manufacturing,
transportation, installation and necessary site work. Open bid contracts are
normally awarded to the lowest responsible bidder.

A fourth salesperson is charged with increasing the Company's sales of buildings
to the commercial and telecommunications markets. In addition, the Company has
two additional salespeople whose focus is on the sale of classrooms in Nevada
and Arizona, and to private schools and day care operators in California.

MANUFACTURING AND ON-SITE INSTALLATION

The Company uses an assembly-line approach in the manufacture of its
standardized classrooms. The process begins with the fabrication of the steel
floor joists. The floor joists are welded to steel frames to form the floor
sub-assembly, which is covered by plywood flooring. Metal roof trusses and
structural supports are fabricated separately and added as the unit progresses
down the assembly-line. Installation of walls, insulation, suspended grid
ceilings, electrical wiring, air conditioning, windows, doors, fire sprinklers,
plumbing and chalkboards follow, with painting and finishing crews completing
the process. Once construction of a standard classroom commences, the building
can be completed in as little as three days. The construction of custom units
on-site, from pre-manufactured components, is similar to factory-built units in
its progressively-staged assembly process but may involve more extensive
structural connections and finish work depending upon the size and type of
building, and typically takes 30 to 60 days to complete.

The Company is vertically-integrated in the manufacture of its standardized
modular classrooms, in that the Company fabricates substantially all of its own
metal components at its facility in Perris, California, including structural
floor and roof joists, exterior roof panels, gutters, down spouts, vents, ramps,
stairs and railings. The Company believes that the ability to fabricate its own
metal components helps it reduce the costs of its products and to control their
quality and delivery schedules. The Company maintains a quality control system
throughout the manufacturing process, under the supervision of its own quality
control personnel and inspectors engaged by its customers. In addition, the
Company tracks the status of all classrooms from sale through installation.

Completed standard classroom units, or components used in customized units, are
loaded onto specially designed flatbed trailers for towing by trucks to the
school building site. Upon arrival at the site, the units are structurally
connected, or components are assembled, and the classroom is installed on its
foundation. Connection with utilities is completed in the same manner as in
conventional on-site construction. Installation of the modular classrooms may be
on a separate foundation, or several units may be incorporated on a common
foundation under a unified roof, so that upon installation they appear to be an
integral part of an existing school facility or function as a larger building,
such as a gymnasium or cafeteria.



                                       5
<PAGE>   6

The Company oversees installation of its modular classrooms on-site, using its
own employees for job supervision as a general contractor and, whenever
possible, for utility hook-ups and other tasks. In many custom projects, the
Company performs or supervises subcontracted electrical, plumbing, grading,
paving and foundation work, landscaping and other site preparation work and
services. Sub-contractors are typically used for larger utility, grading,
concrete and landscaping jobs. The Company has a general contractor's license in
the State of California.

In addition to approvals by the Department of State Architects, licensed
inspectors representing various school districts are on-site at each
manufacturing facility of the Company to continuously inspect the construction
of classrooms for structural integrity. On-site inspections after installation
are also made by local fire departments for purposes of determining adequate
accessibility.

At December 31, 1998 the Company had five manufacturing facilities. Two are
located in Southern California, in Perris, California, which is approximately 60
miles east of Los Angeles. The Company has another two facilities near Lathrop,
California. Lathrop is located approximately 75 miles east of San Francisco. The
fifth manufacturing facility is located in Glendale, Arizona, which is located
in the Phoenix Metropolitan area. At December 31, 1998, the Company had a total
of five production lines in operation.

The standard contractual warranty for the Company's modular relocatable
classrooms is one year, although it may be varied by contract specifications.
Purchased equipment installed by the Company, such as air conditioning units,
carry the manufacturers' standard warranty. Warranty costs have not been
material in the past.

The Company believes that there are multiple sources of supplies available for
all raw materials and equipment used in manufacturing its classrooms, most of
which are standard construction items such as steel, plywood and wallboard.

BACKLOG

The Company manufactures classrooms to fill existing orders only, and not for
inventory. As of December 31, 1998, the backlog of sales orders was
approximately $25.0 million, down from approximately $71.0 million at December
31, 1997 and $58.0 million at December 31, 1998. Only orders, which are
scheduled for completion during the following 12-month period, are included in
the Company's backlog. The rate of booking new contracts can vary from month to
month, and customer changes in delivery schedules can occur. For these reasons,
among others, the Company's backlog as of any particular date may not be
representative of actual sales for any succeeding period.

COMPETITION

The Company believes that, based upon 1997 net sales, it is the largest modular
relocatable classroom manufacturer in California. However, the modular
relocatable classroom industry is highly competitive, with the market divided
among a number of privately-owned companies whose share of the market is smaller
than that of the Company. The Company believes that the nature of the bidding
process, the level of performance bonding required, and the industry's regulated
environment serve as barriers to market entry, and that the expertise of its
management gives it an advantage over competitors. Nevertheless, the Company
believes that additional competitors may enter the market in the future, some of
whom may have significantly greater capital and other resources than are
available to the Company, and that competition may therefore increase.

The Company also believes that its expertise in site preparation and on-site
installation gives it a competitive advantage over many manufacturers of
higher-priced, customized modular units, while its vertically integrated,
assembly-line approach to manufacturing enables the Company to be one of the low
cost producers of standardized, modular relocatable classrooms in California.
Unlike many of its competitors, the Company manufactures most of its own metal
components which allows the Company to maintain quality control over these
components and to produce them at a lower average cost than that at which they
could be obtained from outside sources. The Company also believes that the
quality and appearance of its buildings, and its reputation for reliability in
completion of its contracts, enable it to maintain a favorable position among
its competition.

The Company categorizes its current competition based upon the geographic market
served (Northern California versus Southern California), as well as upon the
relative degree of customization of products sold. Beyond a radius of
approximately 300 miles, the Company believes that transportation costs
typically will either significantly increase the prices at which it bids for
given projects, or will substantially erode the Company's gross profit margins.

The primary competitors of the Company for standardized classrooms are believed
to be Aurora Modular Industries in Southern California and American Modular
Systems in Northern California. Profiles Structures, Inc. in Southern California
and Design Mobile Systems in Northern California are the Company's primary
competitors in the market for higher-priced, customized classrooms. Each of
these four competitors is a privately-owned company.

PERFORMANCE BONDS

A substantial portion of the Company's sales require that the Company provide
bonds to ensure that the contracts will be performed and completed in accordance
with contract terms and conditions, and to assure that subcontractors and
materialmen will be paid. In determining whether to issue a performance bond on
behalf of the Company, bonding companies consider a variety of factors
concerning the specific project to be bonded, as well as the Company's levels of
working capital, shareholders' equity and outstanding indebtedness. From time to
time the Company has had, and in the future may again encounter, difficulty in
obtaining bonding for a given project. Although it has had no difficulty in
obtaining the necessary bonding in the last twelve months, the Company believes
that its difficulty in obtaining bonding for certain large projects from time to
time in the past has been attributable to the Company's levels of working
capital, shareholders' equity and indebtedness, and not to concerns about the
Company's ability to perform the work required under the contract. To assist the
Company in obtaining performance bonds in certain instances, the Company's
executive officers have been required to indemnify the bonding companies against
all losses they might suffer as a result of providing performance bonds for the
Company.

REGULATION OF CLASSROOM CONSTRUCTION

In 1933, the California Legislature adopted the Field Act, which generally
provides that school facilities must be constructed in accordance with more
rigorous structural and seismic safety specifications than are applicable to
general commercial buildings. Under the Field Act, the Department of General
Services, through the Department of State Architects, has prescribed extensive
regulations regarding the design and construction of school facilities, and
reviews all plans for the construction of material modifications to any school
building. Construction authorization is not given unless the school district's
architect certifies that a proposed project satisfies construction cost and
allowable area standards. In addition, the Field Act provides for the submittal
of complete plans, cost estimates, and filing fees by the school district to the
Department of General Services, for the adoption of regulations setting minimum
qualifications for the preparation of plans and specifications, and the
supervision of school construction by a licensed architect or structural
engineer.

Additionally, California legislation provides that certain factory-built school
buildings may be pre-approved by the State for use in school construction. Once
plans and specifications for a given classroom have been pre-approved by the
Department of General Services, school districts can thereafter include in their
application to obtain State funds for new facilities a notification that they
intend to use pre-approved, standardized factory-built classrooms. This
procedure reduces the time required in the State's approval process thereby
providing additional incentive to use factory-built relocatable classrooms. The
Department of General Services provides for the continuous on-site inspection
during actual manufacturing of the classrooms, with the school districts
obligated to reimburse the Department for the costs of such inspection.

LEGISLATION AND FUNDING

The demand for modular relocatable classrooms in California is affected by
various statutes. These statutes, among other things, prescribe the methods by
which the Company's customers, primarily individual school districts, obtain
funding for the construction of new school facilities, and the manner in which
available funding is to be spent by the school districts.

In 1978, Proposition 13 was approved, which rolled back property taxes and
limited the ability of local school districts to rely upon revenue from such
taxes to finance the construction of school facilities. As a result, financing
for new school construction and rehabilitation of existing schools by California
school districts is currently provided, at the state level, by funds derived
from general revenue sources or statewide bond issues, and, at the local level,
by local bond issues and fees imposed on the developers of residential,
commercial and industrial real property ("Developer Fees"). Historically, the
primary source of financing for the purchase or lease of relocatable classrooms
has been state funding.

STATE FUNDING. In November 1996, California implemented the Class Size Reduction
Program in response to overcrowding in classrooms in the state and its assumed
negative impact on learning. An additional impetus for the program was a study
conducted by Tennessee State University which indicated that students in small
classrooms outperformed their peers from larger classes at least through the
eighth grade on standardized tests in math and reading. The goal of the
California Class Size Reduction Program is to reduce public elementary school
class sizes in kindergarten through the third grade. Under this program, schools
that reduce class size to 20 students in those grades receive additional funds.
For the 1996-1997 school year, a school district was entitled to receive $25,000
for each new classroom added which reduced the average class size for a
specified grade level to 20 students or less. Among other ways new classrooms
can quickly and inexpensively be added, school districts may reconfigure
existing space to convert it to classrooms from other uses, or purchase or lease
a modular relocatable classroom.

<PAGE>   8


Until the adoption of the Class Size Reduction Program in 1996, the most
important source of funding at the State level for new school facilities was
through the issuance and sale of statewide general obligation bonds which are
repaid out of the State's General Funds. Proposals to issue such bonds are
placed on statewide ballots from time-to-time in connection with general or
special elections, and require approval by a majority of the votes cast in
connection with such proposals. As in the case of the Class Size Reduction
Program, the State also may annually allocate funds from the State's budget for
the support of school districts and community college districts.

AUTHORITY FOR BOND FINANCING. Under the School Building Lease -- Purchase Law of
1976, the State Allocation Board is empowered to purchase or lease school
facilities using funds from the periodic issuance of general obligation bonds of
the State of California. These purchased or leased school facilities may be made
available by the State Allocation Board to school districts. Certain matching
funds, usually derived from Developer Fees, are required to be supplied by the
school districts seeking state funded facilities. If the school districts
acquire relocatable structures using Developer Fees, the amount of the required
matching funds is reduced by the cost of such facilities. This reduction in
matching funds is intended to provide an incentive for school districts to lease
relocatable classrooms. Prior to November 1998, as a condition of funding any
project under this program, at least 30% of new classroom space to be added must
be comprised of relocatable structures, unless relocatable structures are not
available or special conditions of terrain, climate or unavailability of space
make the use of relocatable structures impractical. In addition, State funds
under this program are not available to school districts which are determined to
have an adequate amount of square footage available for their student
population.

Senate Bill 50, which was passed in November 1998 by the California Legislature,
revised the School Building Lease - Purchase Law of 1976 by eliminating the
requirement that at least 30% of all new classroom space being added using
California state funds must be relocatable classrooms. In general, it replaced
this provision with a requirement that, in order for school districts to
increase the amount of funds to be received from developers in excess of the
current statutory level, the school districts must show that 20% of all
classroom space in the district, not just new space added, consists of
relocatable classrooms. The bill also placed a $9.2 billion bond issue on the
November 1998 ballot, which was approved by the voters. The bill allocates from
the bond issue $2.9 billion for growth and new construction, and $2.2 billion
for modernization and reconstruction through the year 2001. In addition, it
allocates $700 million for class-size reductions to fully implement the program
from kindergarten through third grade. The costs to implement the foregoing will
include land acquisition costs, hiring of new teachers, remodeling of existing
structures and construction of new permanent and relocatable structures. The
bill does not designate the specific usage of funds, and the actual amount spent
on relocatable classrooms will vary among school districts. Implementation of
Senate Bill 50 began the third week of January 1999. The Company does not expect
any significant change in its future operating results due to implementation of
Senate Bill 50.

In response to the adoption of Proposition 13, the State of California adopted
the California Emergency Classroom Law of 1979, pursuant to which the State
Allocation Board may spend up to $35 million per year from available funds to
purchase relocatable classrooms to be leased to school districts. Relocatable
classrooms are not available to school districts under this program if the
school district has available local bond proceeds that could be used to purchase
classroom facilities, unless the district has approved projects pending under
the School Building Lease-Purchase Law of 1976. The State has, in the past,
funded this program primarily from the proceeds of statewide bond issues
approved by voters.

BUDGET ALLOCATIONS. Proposition 98, which was approved in 1988, requires the
State to allocate annually from the State's budget, for the support of school
districts and community college districts, a minimum amount equal to the same
percentage of funds as was appropriated for the support of those institutions in
fiscal year 1986-87. While this requirement may be suspended for a given year by
emergency legislation, it has the effect of limiting the ability of the
California legislature to reduce the level of school funding from that in
existence in 1986-87. The State raises the necessary funds through proceeds from
the sale of statewide bond issues, income tax revenues and other revenues. A
recent reduction in California's corporate tax rates, and a proposed reduction
in personal income tax rates, may affect future levels of the State's income tax
revenues.

LOCAL FUNDING. Local school districts in California have the ability to issue
local general obligation bonds for the acquisition and improvement of real
property for school construction. These bond issues require the approval of
two-thirds of the voters in the district and are repaid using the proceeds of
increases in local property taxes. A local school district may also levy
Developer Fees on new development projects in the district, subject to a maximum
rate set by state law. The Developer Fees can only be levied if the project can
be shown to contribute to the need for additional school facilities and the fee
levied is reasonably related to such need. In addition, California law provides
for the issuance of bonds by Community Facilities Districts which can be formed
by a variety of local government agencies, including school districts. These
districts, known as "Mello-Roos" districts, can have flexible boundaries and the
tax imposed to repay the bonds can be based on property use, acreage, population
density or other factors.

OTHER LEGISLATION

California legislation adopted in 1989 provides that school districts which
currently lease any building which does not meet the prescribed structural
standards must have replaced nonconforming buildings with conforming ones by
September 1, 1990. However, any district has the right to request a one-time
waiver for a maximum of three years upon presentation of satisfactory evidence
to the State Allocation Board that the district is proceeding in a timely
fashion with a program that will eliminate the need for the nonconforming
facilities within that time period. The State has authorized districts to renew
these waivers through 2000 and may grant further waivers. The Company
understands that a number of school districts have requested and been granted
such waivers. Based upon information received by the State Allocation Board from
school districts and provided to the Company, it is believed that there are
approximately 4,500 trailers currently being used as classrooms by school
districts throughout California that eventually must be replaced with conforming
facilities by these school districts.

California has taken steps to encourage local school districts to adopt
year-round school programs to help increase the use of existing school
facilities and reduce the need for additional school facilities. School
districts requesting state funding under the School Building Lease-Purchase Law
of 1976 or the Emergency Classroom Law of 1979 discussed above must submit a
study examining the feasibility of implementing in the district a year-round
educational program that is designed to increase pupil capacity in the district
or in overcrowded high school attendance areas. The feasibility study
requirement is waived, however, if the district demonstrates that emergency or
urgent conditions exist in the district that necessitate the immediate need for
relocatable buildings. The demand for new school facilities, including
relocatable classrooms, would be adversely affected in the event that a
significant number of California school districts implemented year-round school
programs. In addition, a significant increase in the level of voluntary or
mandatory busing of students from overcrowded schools to schools with excess
capacity could adversely affect demand for new school facilities.

ENVIRONMENTAL MATTERS

The Company is subject to a variety of federal, state and local governmental
regulations related to the storage, use and disposal of any hazardous materials
used by the Company in connection with the manufacture of its products. Both the
governmental regulations and the costs associated with complying with such
regulations are subject to change in the future.

EMPLOYEES

At December 31, 1998, the Company had 481 employees, including 429 in
manufacturing, 6 in sales, 17 in operations and 29 in general management and
administration. The Company's employees are not represented by a labor union,
and it has experienced no work stoppages. The Company believes that its employee
relations are good.

ITEM 2. PROPERTIES

The Company's principal executive and administrative facilities are located in
approximately 12,000 square feet of modular buildings at its primary
manufacturing facility located in Perris, California. This manufacturing
facility occupies twenty-five acres, with approximately 226,000 square feet of
covered production space under roof, pursuant to a lease expiring in 2014. A
second facility in Perris occupies approximately thirty acres, with
approximately 120,000 square feet of covered production space under roof,
pursuant to a lease expiring in 2014. This second facility also includes
approximately 80,000 square feet under roof used as a metal working facility.
The Company's third plant consists of a 400,000 square foot manufacturing
facility on a 30-acre site in Lathrop, California that is leased through 2019.
The fourth plant, which was leased for up to five years in October 1996,
consists of approximately 50,000 square feet of manufacturing area on a 4-acre
site in Patterson, California. The fifth plant consists of approximately 30,000
square feet of manufacturing area on a 4-acre site in Glendale, Arizona. The
Company believes that its facilities are well maintained and in good operating
condition, and meet the requirements for its immediately foreseeable business
needs. Each of the Company's facilities at December 31, 1998, other than the
Patterson plant and Arizona plant, are leased from an affiliate. See "Management
- -- Certain Transactions."

ITEM 3. LEGAL PROCEEDINGS

The Company is from time to time involved in various lawsuits related to its
ongoing business operations, primarily collection actions or vendor disputes. In
the opinion of management, no pending lawsuit will result in any material
adverse effect upon the Company or its financial condition.

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

Following are the unaudited pro forma combined condensed balance sheet as of
December 31, 1998 and the unaudited pro forma combined condensed income
statements for the year ended December 31, 1998 and 1997 of Modtech, Inc. and
SPI Holdings, Inc. These statements are based on the historical consolidated
financial statements of Modtech, Inc. and SPI Manufacturing, Inc., combined, and
are adjusted to give effect to the mergers. In addition, pro forma adjustments
have been made for the acquisitions consummated by SPI prior to the merger.
Certain reclassifications have been made to the historical financial statements
to conform with this pro forma presentation.

The pro forma adjustments are based upon preliminary estimates, information
currently available and certain assumptions that management believes are
reasonable under the circumstances. Holding's actual consolidated financial
statements will reflect the effects of the mergers on and after February 16,
1999 rather than the dates indicated above. The unaudited pro forma combined
condensed financial statements neither purport to represent what the combined
results of operations or financial condition actually would have been had the
mergers, in fact, occurred on the assumed dates, nor to project the combined
results of operations and financial position for any future period.

These statements should be read in conjunction with (i) Modtech Inc.'s
historical financial statements and notes thereto included elsewhere herein,
and (ii) Holdings' Joint Proxy Statement/Prospectus dated January 11, 1999
which is included in Holding's Registration Statement on Form S-4 filed with
the Securities and Exchange Commission (Commission File No. 333-69033).

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
        FINANCIAL CONDITION

GENERAL

Since its inception in 1982, the Company's principal business has been the
design, manufacture, marketing and installation of modular relocatable
classrooms. The Company's primary customers consist of individual school
districts located in California and the State of California. The need for new
classrooms in California school districts is generally governed by the number of
students per class, which is a function of the net migration of families into
and out of school districts and the total number of new students entering the
school system in any given year.

Specific provisions of California legislation govern the amount of the State's
budget that must be directed toward the public school system. A portion of these
funds may be allocated for the addition of new classrooms. In addition, the
State can raise funds to build or add new classrooms through the issuance of
general obligation bonds. See "Business -- Legislation and Funding."

In the early to mid 1990's, California suffered through a recession that
resulted in statewide budgetary constraints. During this period, the amount of
State funds available for the addition of new classrooms was severely limited.
As a result, the Company experienced a decline in net sales in 1992 and 1993,
and net sales in 1994 and 1995 were essentially the same as those generated in
1993. In response, the Company initiated a cost control program that included
layoffs of approximately 80% of its staff as compared to the June 1991 work
force, and temporarily closed its plant in Lathrop, California. In addition, the
Chief Executive Officer of the Company agreed to a 50% salary reduction and each
of the Company's other top management personnel agreed to a 10% salary
reduction.

Due in large measure to the amelioration of the State budget crises and the
realization that the need for new classrooms in California far exceeded supply,
beginning in the second half of 1996 and continuing into 1997 and 1998, the
State has increased the amount of funds targeted specifically for the addition
of new classrooms. In November 1996, the State implemented the Class Size
Reduction Program, the goal of which is to reduce public school class sizes in
kindergarten through the third grade. For the 1996-1997 school year the State
spent $822 million under this program, including $200 million specifically for
facilities, which may be relocatable classrooms. Primarily as a result of the
implementation of the Class


                                       15

<PAGE>   16

Size Reduction Program, the Company's net sales increased to $134.0 million in
1997 as compared to $49.9 million for the year ended December 31, 1996 and $19.4
million in 1995. In addition, a $9.2 billion school construction bond issue was
approved in November 1998. $2.9 billion of the bond issue is allocated for
growth and new construction and $2.2 billion for modernization and
reconstruction through the year 2001. It additionally allocated $700 million for
class-size reductions to fully implement the program from kindergarten through
third grade. See "Business -- Legislation and Funding." In response to the
increased demand for its modular relocatable classrooms, the Company re-opened
the Northern California Lathrop plant in 1997 and expanded its Southern
California production capacity in Perris in 1998.

</TABLE>


YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

Net sales for the year ended December 31, 1998 decreased to $127.6 million, a
decrease of $6.4 million, or approximately 4.8%, from $134.0 million in 1997.
The decrease in 1998 was due in part to the fact that the California Legislature
was more than two months late in passing the state budget. Additionally, there
was a delay in allocating the funds from the $9.2 billion school construction
bond issue which was passed in November 1998.

For the year ended December 31, 1998, gross profit was $29.9 million, an
increase of $3.2 million, or approximately 11.9%, over 1997 gross profit of
$26.7 million. Gross profit percentage of net sales increased to 23.4% in 1998
from 19.9% in 1997. The increase in gross profit as a percentage of net sales
was primarily attributable to the realization of manufacturing efficiencies.

In 1998, selling, general and administrative expenses decreased to $4.7 million
from $5.2 million, due to decreases in the number of employees and a decrease in
selling costs. As a percentage of net sales, selling, general and administrative
expenses decreased to 3.7% in 1998 from 3.8% in 1997.

Due to higher cash balance and reduced line of credit borrowing, the year ended
December 31, 1998 reflects net interest income of $1,097,000, compared to net
interest expense of $909,000 for the same period in 1997, a favorable increase
of $2,006,000 or 220.7%.

The provision for income taxes was $9.7 million for the year ended December 31,
1998, compared to $7.7 million for 1997. The Company's effective tax rate
decreased to 37.0% for the year ended December 31, 1998 from 37.2% for the year
ended December 31, 1997. The effective tax rate in 1998 was positively impacted
by a reduction in the federal valuation allowance. The effective tax rate in
1997 was positively impacted by the utilization for federal income tax purposes
of net operating loss carryforwards generated in prior years.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

Net sales for the year ended December 31, 1997 increased to $134.0 million, an
increase of $84.1 million, or approximately 169%, from $49.9 million in 1996.
The increase in 1997 was due principally to the amelioration of the State of
California budget deficit and the implementation during the year of the Class
Size Reduction Program for kindergarten through third grade classes in
California's public elementary schools.

For the year ended December 31, 1997, gross profit was $26.7 million, an
increase of $19.4 million, or approximately 266%, over 1996 gross profit of $7.3
million. Gross profit percentage of net sales increased to 19.9% in 1997 from
14.5% in 1996. The increase in gross profit as a percentage of net sales was
primarily attributable to the increased volume, utilization of a previously idle
facility, and the realization of manufacturing efficiencies.

In 1997, selling, general and administrative expenses increased to $5.2 million
from $2.3 million, due to increases in the number of employees and an increase
in selling costs. However, as a percentage of net sales, selling, general and
administrative expenses decreased to 3.8% in 1997 from 4.7% in 1996.

Due to increased volume and average borrowings outstanding, net interest expense
increase from $422,000 in 1996 to $909,000 for 1997.

The provision for income taxes was $7.7 million for the year ended December 31,
1997, compared to $208,000 for 1996. The Company's effective tax rate increased
to 37.2% for the year ended December 31, 1997 from 4.6% for the year ended
December 31, 1996. The effective tax rate in 1996 was positively impacted by the
utilization for federal income tax purposes of net operating loss carryforwards
generated in prior years.

LIQUIDITY AND CAPITAL RESOURCES

Since the 1994 Financing described below, the Company has funded its operations
and capital expenditures with cash generated internally by operations,
supplemented by borrowings under various credit facilities. During the years
ended December 31, 1996, 1997 and 1998, the Company's operations provided (used)
cash in the amounts of approximately ($4.9 million), $2.0 million and $32.8
million, respectively. At December 31, 1998, the Company had approximately $40.1
million in cash.

The Company's revolving loan facility, which was scheduled to expire in
September 2000, was paid off on December 4, 1998.

The Company had working capital of $14.1 million, $36.4 million and $52.1
million at December 31, 1996, 1997 and 1998, respectively. In 1998, current
assets increased by $13.2 million, with an increase of $28.5 million in cash, an
increase of $1.4 million in deferred tax assets and an increase of $1.3 million
in due from affiliates, offset by a decrease of $8.6 million in contracts
receivable and a decrease of $12.2 million in costs and estimated earnings in
excess of billings. Current liabilities decreased by $2.5 million, with various
accrued liabilities and current maturities of long-term debt decreasing by $1.9
million and $1.4 million, respectively, offset by a $0.7 million increase in
accounts payable. In 1997, contracts receivable, costs and estimated earnings in
excess of billings on contracts increased by $11.2 million and $6.9 million,
respectively, as the Company's net sales increased significantly due to the
implementation of the State's Class Size Reduction Program. Accrued liabilities
increased by $6.1 million in 1997, also as a result of the increase in net
sales.


                                       17

<PAGE>   18

Capital expenditures amounted to $2.0 million, $4.1 million and $2.1 million
during the years ended December 31, 1996, 1997 and 1998, respectively. In 1996,
the majority of expenditures were as a result of the re-opening of the Company's
Lathrop, California Manufacturing facility. In 1997 and 1998, the majority of
expenditures were related to the construction of an additional production line
at one of its Perris, California facilities.

The Company had a $4.0 million Industrial Development Bond issued by the
Industrial Development Authority of the County of San Joaquin, California, the
net proceeds of which were used to partially finance the $6.0 million cost of
construction of the Company's Lathrop, California facility. The loan was paid in
full during 1998.

In May 1994, the Company raised net proceeds of approximately $2.7 million
through the sale of 2,850,000 shares of Series A Preferred Stock to several
private investors who are Selling Shareholders in this Offering (the "1994
Financing"). In April 1996, all of the Series A Preferred Stock was converted
into 2,850,000 shares of Common Stock. In December 1996, warrants issued to the
investors in connection with the 1994 Financing were exercised, resulting in
cash proceeds to the Company of approximately $1.6 million and the issuance of
2,204,000 additional shares of Common Stock.

Management believes that the Company's existing product lines and manufacturing
capacity will enable the Company to generate sufficient cash through operations,
supplemented by periodic use of Holding's bank line of credit, to finance the
Company's business over the next twelve months. However, additional cash
resources may be required if the Company's rate of growth exceeds currently
anticipated levels. Moreover, it may prove necessary for the Company to
construct or acquire additional manufacturing facilities in order for the
Company to compete effectively in new market areas or states which are beyond a
300 mile radius from one of its production facilities. The construction or
acquisition of new facilities could require significant additional capital. For
these reasons, among others, the Company may need additional debt or equity
financing in the future. There can be, however, no assurance that the Company
will be successful in obtaining such additional financing, or that any such
financing will be available on terms acceptable to it.

NEW ACCOUNTING PRONOUNCEMENT

In June 1998, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (SFAS 133). SFAS 133 establishes accounting
and reporting standards for derivative instruments embedded in other contracts,
and hedging activities. SFAS 133 is effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. Application of SFAS 133 is not expected to
have a material impact on the Company's financial position, results of
operations or liquidity.

YEAR 2000

The "year 2000" issue concerns the potential exposures related to the automated
generation of business and financial misinformation resulting from the
application of computer programs which have been written using two digits,
rather than four, to define the applicable year of business transactions. When
the year 2000 begins, programs with such date-related logic will not be able to
distinguish between the years 1900 and 2000, potentially causing software and
hardware to fail, generating erroneous calculations or presenting information in
an unusable format.

The Company is dependent on multiple computer servers and the third-party
computer programs running on them to provide data in support of its accounting
and engineering functions. In recognition of the potential year 2000 problem, in
November 1997, the Company began a program to replace all of its existing
engineering and accounting software with new software that is warranted by its
vendors as being year 2000 compliant. The software replacement program was
completed in November 1998 at a total cost of approximately $250,000. SPI's
computer data is currently being transferred to the Company's computer system.
The Company estimates that this transfer will be completed by the end of the
second quarter of 1999 at a cost of approximately $100,000.

The Company has relationships with various third parties on whom it relies to
provide goods and services necessary for the manufacture and distribution of its
products. These include suppliers and vendors. As part of its determination of
year 2000 readiness, the Company had identified material relationships with
third-party vendors and is in the process of assessing the status of their
compliance through the use of questionnaires. The Company expects this process
will be completed by the second quarter of 1999 at a cost of approximately
$100,000.

The total cost of the Company's year 2000 efforts, including hardware, software,
related consulting costs, assessment of third-party compliance, and transfer of
SPI data is estimated to be about $500,000, and is not material to the Company's
financial statements.

The Company's construction materials are available through numerous independent
sources. Due to the broad diversification of these sources, the risk associated
with potential business interruptions as a result of year 2000 non-compliance by
one or more sources is not considered significant.

The Company's primary customers are California school districts, each of which
obtains its funds for paying the Company's invoices through the computer system
operated by the State of California. If this system does not properly function
after January 1, 2000, it could result in a temporary shutdown of portions of
the state government, in which case, payment of the Company's invoices would be
delayed, and new purchase orders may not be processed. If the shutdown lasted
for more than 60 days, the Company would experience a severe cash shortage and a
material decline in revenue during the period of the government shutdown. The
cash shortage can be alleviated to some degree by borrowings from Holding's line
of credit and by reductions in work force and possible temporary plant closures.
The Company does not believe it can design or implement any other contingency
plans that will mitigate the effects of such a government shutdown.

It is anticipated that the steps the Company has taken and is continuing to take
deal with the year 2000 problem will reduce the risk of significant business
interruption, but there is no assurance that this outcome will be achieved.
Failure to detect and correct all internal instances of non-compliance or the
inability of third parties to achieve timely compliance could result in the
interruption of normal business operations which could, depending on its
duration, have a material adverse effect on the Company's financial statements.

SEASONALITY

Historically, the Company's quarterly revenues have been highest in the second
and third quarters of each calendar year because a large number of orders for
modular classrooms placed by school districts require that classrooms be
constructed, delivered and installed in time for the upcoming new school year
which generally commences in September. The Company has typically been able to
add employees as needed to respond to the corresponding increases in
manufacturing output required by such seasonality to meet currently foreseeable
increases in this seasonal demand. In addition, the Company's operating margins
may vary on a quarterly basis depending upon the mix of revenues between
standardized classrooms and higher margin customized classrooms and the timing
of the completion of large, higher margin customized contracts.

INFLATION

During the past three years, the Company has not been adversely affected by
inflation, because it has been generally able to pass along to its customers
increases in the costs of labor and materials. However, there can be no
assurance that the Company's business will not be affected by inflation in the
future.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors
Modtech, Inc.:


We have audited the accompanying consolidated balance sheets of Modtech, Inc.
and subsidiary as of December 31, 1997 and 1998, and the related consolidated
statements of income, shareholders' equity and cash flows for each of the years
in the three-year period ended December 31, 1998. In connection with our audits
of the consolidated financial statements, we have also audited the financial
statement schedule as listed in the accompanying index. These consolidated
financial statements and financial statement schedule are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
consolidated financial statements and financial statement schedule based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the consolidated financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Modtech, Inc. and
subsidiary as of December 31, 1997 and 1998 and the results of their operations
and their cash flows for each of the years in the three-year period ended
December 31, 1998, in conformity with generally accepted accounting principles.
Also in our opinion, the related financial statement schedule, when considered
in relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

                   Notes to Consolidated Financial Statements

                        December 31, 1996, 1997 and 1998


(1)      DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         DESCRIPTION OF BUSINESS

         Modtech, Inc. and its majority owned subsidiary (the Company) design,
         manufacture, market and install modular relocatable classrooms and
         other modular buildings for commercial use.

         The Company's classrooms are sold primarily to California school
         districts. The Company also sells classrooms to the State of California
         and to leasing companies, who lease the classrooms principally to
         California school districts. The Company's modular classrooms include
         standardized units prefabricated at its manufacturing facilities, as
         well as customized units that are modular in design but constructed on
         site using components manufactured by the Company.

         In addition to modular relocatable classrooms, the Company also
         manufactures modular, portable buildings which can be used as office
         facilities and construction trailers and for other commercial purposes,
         including modular structures that house and shelter electronic
         equipment used in the wireless telecommunications industry.

         PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the financial statements
         of Modtech, Inc. and its majority owned subsidiary. All significant
         intercompany balances and transactions have been eliminated in
         consolidation.

         USE OF ESTIMATES

         Preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosures of contingent assets and liabilities at the
         date of the financial statements and the reported amounts of revenues
         and expenses during the reported period. Actual results could differ
         from those estimates.

         FAIR VALUE OF FINANCIAL INSTRUMENTS

         The carrying value of cash, contracts receivable and note receivable,
         costs and estimated earnings in excess of billings on contracts,
         prepaid and other assets, accounts payable, accrued liabilities,
         billings in excess of estimated earnings on contracts and notes payable
         are measured at cost which approximates their fair value.

         CONSTRUCTION CONTRACTS

         Contracts are recognized using the percentage-of-completion method of
         accounting and, therefore, take into account the costs, estimated
         earnings and revenue to date on contracts not yet completed. Revenue
         recognized is that percentage of the total contract price that cost
         expended to date bears to anticipated final total cost, based on
         current estimates of costs to complete.

<PAGE>   31



                                  MODTECH, INC.

              Notes to Consolidated Financial Statements, Continued



         Contract costs include all direct material and labor costs and those
         indirect costs related to contract performance, such as indirect labor,
         supplies, tools, repairs, and depreciation costs. Selling, general, and
         administrative costs are charged to expense as incurred. At the time a
         loss on a contract becomes known, the entire amount of the estimated
         ultimate loss is recognized in the financial statements.

         The current asset, "Costs and Estimated Earnings in Excess of Billings
         on Contracts," represents revenues recognized in excess of amounts
         billed. The current liability, "Billings in Excess of Costs and
         Estimated Earnings on Contracts," represents billings in excess of
         revenues recognized.

         The current contra asset, "Allowance for Contract Adjustments," is
         management's estimated adjustments to contract amounts due to disputes
         and or litigation.

         INVENTORIES

         Inventories are valued at the lower of cost or market. Cost is
         determined by the first-in, first-out (FIFO) method. Inventories,
         generally include only raw materials, as any work-in-process or
         finished goods are accounted for in percentage of completion
         allocations.

         PROPERTY AND EQUIPMENT

         Property and equipment are stated at cost. Depreciation and
         amortization are calculated using the straight-line and accelerated
         methods over the following estimated useful lives:

<TABLE>
<S>                                           <C>     
               Leasehold improvements         15 to 31 years
               Machinery and equipment          5 to 7 years
               Trucks and automobiles           3 to 5 years
               Office equipment                 5 to 7 years
</TABLE>


         IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS HELD FOR DISPOSAL

         Long-lived assets and certain identifiable intangibles are reviewed for
         impairment whenever events or changes in circumstances indicate that
         the carrying amount of an asset may not be recoverable. Recoverability
         of assets to be held and used is measured by a comparison of the
         carrying amount of an asset to future net cash flows expected to be
         generated by the asset. If such assets are considered to be impaired,
         the impairment to be recognized is measured by the amount by which the
         carrying amount of the assets exceed the fair value of the assets.
         Assets to be disposed of are reported at the lower of the carrying
         amount of fair value less costs to sell.

         STOCK OPTION PLANS

         Prior to January 1, 1996, the Company accounted for stock option plans
         in accordance with the provisions of Accounting Principles Board (APB)
         Opinion No. 25, "Accounting for Stock Issued to Employees," and related
         interpretations. As such, compensation expense would be recognized on
         the date of grant only if the current market price of the underlying
         stock exceeded the exercise price. On January 1, 1996, the Company
         adopted Statement of Financial Accounting Standard No. 123 (SFAS No.
         123), "Accounting for Stock-Based Compensation," which permits entities
         to recognize as expense over the vesting period the fair value of all
         stock-based awards on the date of grant. Alternatively, SFAS No. 123
         also allows entities to continue to apply the provisions of APB Opinion
         No. 25 and provide pro forma net income and pro forma earnings per
         share disclosures for employee stock option grants made in 1995 and
         future years as if the fair-value-based method defined in SFAS No. 123
         had been applied. The Company has elected to

                                  MODTECH, INC.

              Notes to Consolidated Financial Statements, Continued


         continue to apply the provision of APB Opinion No. 25 and provide the
         pro forma disclosure provisions of SFAS No. 123.

         EARNINGS PER SHARE

         Effective December 31, 1997, the Company adopted Statement of Financial
         Accounting Standards No. 128, "Earnings per Share" (SFAS No. 128). This
         statement replaced the previously reported primary and fully diluted
         earnings per share with basic and diluted earnings per share. Unlike
         primary earnings per share, basic earnings per share excludes any
         dilutive effects of options. Diluted earnings per share is very similar
         to the previously reported fully diluted earnings per share. All
         earnings per share amounts have been restated to conform to the SFAS
         No. 128 requirements.

         INCOME TAXES

         Income taxes are accounted for under the asset and liability method.
         Deferred tax assets and liabilities are recognized for the future tax
         consequences attributable to differences between the financial
         statement carrying amounts of existing assets and liabilities and their
         respective tax bases and tax credit carryforwards. Deferred tax assets
         and liabilities are measured using enacted tax rates expected to apply
         to taxable income in the years in which those temporary differences are
         expected to be recovered or settled. The effect on deferred tax assets
         and liabilities of a change in tax rates is recognized in income in the
         period that includes the enactment date.

         RECLASSIFICATION

         Certain amounts in the 1996 and 1997 financial statements have been
         reclassified to conform to the 1998 presentation.

         The valuation allowance for deferred tax assets as of December 31, 1997
         and 1998 was $1,059,576 and $0, respectively. The net change in the
         total valuation allowance for the years ended December 31, 1997 and
         1998 was a decrease of $99,138 and $1,059,576, respectively. Management
         believes the existing net deductible temporary differences will reverse
         during periods in which the Company will have the ability to utilize
         the deductions to offset other reversing temporary differences which
         give rise to taxable income.

(10)     STOCK OPTIONS

         In 1989, the Company's shareholders approved a stock option plan (the
         1989 Plan). The 1989 Plan provides for the grant of both incentive and
         non-qualified options to purchase up to 400,000 shares of the Company's
         common stock. The incentive stock options can be granted only to
         employees, including officers of the Company, while non-qualified stock
         options can be granted to employees, non-employee officers and
         directors, consultants, vendors, customers and others expected to
         provide significant services to the Company.

         The exercise price of the stock options cannot be less than the fair
         market at the date of the grant (110% if granted to an employee who
         owns 10% or more of the common stock).

         Stock options outstanding under the 1989 Plan are summarized as
         follows:

         Pro forma net income reflects only options granted since January 1,
         1995. Therefore, the full impact of calculating compensation cost for
         stock options under SFAS No. 123 is not reflected in the pro forma net
         income amounts presented above because compensation cost is reflected
         over the options' vesting period of four years and compensation cost
         for options granted prior to January 1, 1995 is not considered.




(11)     5% CONVERTIBLE PREFERRED STOCK

         In May of 1994, in a private transaction without registration under the
         Securities Act, the Company sold 2,850,000 shares of Series A 5%
         Convertible Preferred Stock. The Preferred Stock was sold at $1.00 per
         share with proceeds before costs and expenses of $2,850,000. All of the
         Series A 5% Convertible Preferred Stock was converted into Common Stock
         during 1996. In connection with this private placement of the Series A
         5% Preferred Stock, the shareholders were granted warrants to purchase
         an aggregate of 1,385,000 shares of common stock at $1.50 (subject to
         adjustment in certain events), as well as warrants to purchase an
         aggregate of 1,375,000 additional shares at $2.00 per share (subject to
         adjustments in certain events). All warrants were either exercised or
         expired during 1996. Dividends in the amount of $47,500 were declared
         for the year ended December 31, 1996.

(16)     SECONDARY STOCK OFFERING

         In November 1997 the Company held a secondary offering of 1,000,000

         proceeds to the Company were $18,600,000, after the deduction of
         underwriting discounts, commissions and offering expenses paid by the
         Company.

         The Company used a portion of the proceeds to repay amounts outstanding
         under the Company's $20,000,000 revolving loan agreement with a bank
         (note 5). The remaining net proceeds were used as additions to working
         capital.

(17)     WARRANTY

         The Company provides a one year warranty relating to the workmanship on
         their modular units. Purchased equipment installed by the Company, such
         as air conditioning units, carry the manufacturers' standard warranty.
         To date, warranty costs incurred on completed contracts have been
         immaterial.

(18)     PENDING CLAIMS AND LITIGATION

         The Company is involved in various claims and legal actions arising in
         the ordinary course of business. In the opinion of management, the
         outcome of the claims will not have a material adverse effect on the
         Company's consolidated financial position, results of operations or
         liquidity.

(19)     SUBSEQUENT EVENTS

         SPI Merger. On February 16, 1999, Modtech, Inc. ("Modtech") and SPI
         Holdings, Inc., a Colorado corporation ("SPI") merged pursuant to the
         Agreement and Plan of Reorganization and Merger, dated as of September
         28, 1998 (the "Merger Agreement"), between Modtech and SPI, and the
         mergers contemplated therein. SPI is a designer, manufacturer and
         wholesaler of commercial and light industrial modular buildings.
         Pursuant to the Merger Agreement, SPI was merged with a subsidiary of
         Modtech Holdings, Inc. ("Holdings"), a newly formed Delaware
         corporation (the "SPI Merger"). Concurrently, Modtech was merged with a
         separate subsidiary of Holdings (the "Modtech Merger"). Pursuant to the
         mergers, both SPI and Modtech became wholly owned subsidiaries of
         Holdings. The SPI Merger will be accounted for by the purchase method
         of accounting.

         In connection with the SPI Merger, SPI stockholders received
         approximately $8 million in cash and approximately 4.3 million shares
         of Holdings Common Stock. Holdings refinanced approximately $32 million
         of SPI debt. In connection with the Modtech Merger, Modtech
         stockholders received approximately $40 million in cash, approximately
         8.3 million shares of Holdings Common Stock and 388,939 shares of
         Holdings Series A Preferred Stock. In connection with both mergers,
         Holdings incurred a total of approximately $51 million of debt.

         Coastal Acquisition. In March 1999, Holdings purchased 100% of the
         stock of Coastal Modular Buildings, Inc. ("Coastal"). Coastal designs
         and manufactures modular relocatable classrooms and other modular
         buildings for commercial use. Coastal is based in St. Petersburg,
         Florida. The acquisition will be accounted for by the purchase method
         of accounting.

         sum of the aggregate principal amount of outstanding Revolving Loans
         shall not exceed THIRTY MILLION DOLLARS ($30,000,000) (as such

         shall be outstanding hereunder at any time (it being understood that,
         for purposes hereof, Eurodollar Loans with different Interest Periods
         shall be considered as separate Eurodollar Loans, even if they begin on
         the same date, although borrowings, extensions and conversions may, in
         accordance with the provisions hereof, be combined at the end of
         existing Interest Periods to constitute a new Eurodollar Loan with a
         single Interest Period). Revolving Loans hereunder may be repaid and
         reborrowed in accordance with the provisions hereof.

                  (b)      Revolving Loan Borrowings.

                           (i)      Notice of Borrowing. The Borrower shall

                  North Carolina time) on the Business Day prior to the date of
                  the requested borrowing in the case of Base Rate Loans, and on
                  the third Business Day prior to the date of the requested
                  borrowing in the case of Eurodollar Loans. Each such request

                  borrowing (which shall be a Business Day), (C) the aggregate

                  shall be comprised of Base Rate Loans, Eurodollar Loans or a
                  combination thereof, and if Eurodollar Loans are requested,
                  the Interest Period(s) therefor. If the Borrower shall fail to
                  specify in any such Notice of Borrowing (I) an applicable
                  Interest Period in the case


                                       27

                  of a Eurodollar Loan, then such notice shall be deemed to be a
                  request for an Interest Period of one month, or (II) the type
                  of Revolving Loan requested, then such notice shall be deemed
                  to be a request for a Base Rate Loan hereunder. The
                  Administrative Agent shall give notice to each affected Lender
                  promptly upon receipt of each Notice of Borrowing pursuant to
                  this Section 2.1(b)(i), the contents thereof and each such
                  Lender's share of any borrowing to be made pursuant thereto.

                           (ii)     Minimum Amounts. Each Eurodollar Loan that
                  is a Revolving Loan shall be in a minimum aggregate principal
                  amount of $1,000,000 and integral multiples of $100,000 in
                  excess thereof (or the remaining amount of the Revolving
                  Committed Amount, if less). Each Base Rate Loan that is a
                  Revolving Loan shall be in a minimum aggregate principal
                  amount of $250,000 and integral multiples of $25,000 in excess

                  Amount, if less).

                           (iii)    Advances. Each Lender will make its
                  Revolving Commitment Percentage of each Revolving Loan
                  borrowing available to the Administrative Agent for the
                  account of the Borrower as specified in Section 3.15(a), or in
                  such other manner as the Administrative Agent may specify in
                  writing, by 1:00 P.M. (Charlotte, North Carolina time) on the
                  date specified in the applicable Notice of Borrowing in
                  Dollars and in funds immediately available to the
                  Administrative Agent. Such borrowing will then be made
                  available to the Borrower by the Administrative Agent by
                  crediting the account of the Borrower on the books of such
                  office with the aggregate of the amounts made available to the
                  Administrative Agent by the Lenders and in like funds as
                  received by the Administrative Agent.

                  (c)      Repayment. The principal amount of all Revolving
         Loans shall be due and payable in full on the Maturity Date, unless
         accelerated sooner pursuant to Section 9.2.

                  (d)      Interest.  Subject to the provisions of Section 3.1,

                           (i)      Base Rate Loans. During such periods as
                  Revolving Loans shall be comprised in whole or in part of Base
                  Rate Loans, such Base Rate Loans shall bear interest at a per
                  annum rate equal to the Adjusted Base Rate.

                           (ii)     Eurodollar Loans. During such periods as
                  Revolving Loans shall be comprised in whole or in part of
                  Eurodollar Loans, such Eurodollar Loans shall bear interest at
                  a per annum rate equal to the Adjusted Eurodollar Rate.

         Interest on Revolving Loans shall be payable in arrears on each
         applicable Interest Payment Date (or at such other times as may be
         specified herein).

                  (e)      Revolving Notes. The Revolving Loans made by each
         Lender shall be evidenced by a duly executed promissory note of the
         Borrower to such Lender in an original principal amount equal to such
         Lender's Revolving Commitment Percentage of the Revolving Committed
         Amount and in substantially the form of Exhibit 2.1(e).

         2.2      LETTER OF CREDIT SUBFACILITY OF THE REVOLVER.

                  (a)      Issuance. Subject to the terms and conditions hereof
         and of the LOC Documents, if any, and any other terms and conditions
         which the Issuing Lender may reasonably require and in reliance upon
         the representations and warranties set forth herein, the Issuing Lender
         agrees to issue, and each Lender severally agrees to participate in the
         issuance by the Issuing Lender of, standby and trade Letters of Credit
         in Dollars from time to time from the Closing Date until the date five
         (5) days prior to the Maturity Date as the Borrower may request, in a
         form acceptable to the Issuing Lender; provided, however, that (i) the
         LOC Obligations outstanding shall not at any time exceed TEN MILLION
         DOLLARS ($10,000,000) (the "LOC Committed Amount") and (ii) the sum of
         the aggregate outstanding principal amount of Revolving Loans plus LOC
         Obligations plus Swingline Loans shall not at any time exceed the
         Revolving Committed Amount. No Letter of Credit shall (x) have an
         original expiry date more than one year from the date of issuance or
         (y) as originally issued or as extended, have an expiry date extending
         beyond the Maturity Date. Each Letter of Credit shall comply with the
         related LOC Documents. The issuance and expiry dates of each Letter of
         Credit shall be a Business Day.

                  (b)      Notice and Reports. The request for the issuance of a
         Letter of Credit shall be submitted by the Borrower to the Issuing
         Lender at least three (3) Business Days prior to the requested date of
         issuance. The Issuing Lender will, at least quarterly and more
         frequently upon request, disseminate to each of the Lenders a detailed
         report specifying the Letters of Credit which are then issued and
         outstanding and any activity with respect thereto which may have
         occurred since the date of the prior report, and including therein,
         among other things, the beneficiary, the face amount and the expiry
         date, as well as any payment or expirations which may have occurred.

                  (c)      Participation. Each Lender, upon issuance of a Letter
         of Credit, shall be deemed to have purchased without recourse a
         Participation Interest from the Issuing Lender in such Letter of Credit
         and the obligations arising thereunder and any collateral relating
         thereto, in each case in an amount equal to its pro rata share of the
         obligations under such Letter of Credit (based on the respective
         Revolving Commitment Percentages of the Lenders) and shall absolutely,
         unconditionally and irrevocably assume and be obligated to pay to the
         Issuing Lender and discharge when due, its pro rata share of the
         obligations arising under such Letter of Credit. Without limiting the
         scope and nature of each Lender's Participation Interest in any Letter
         of Credit, to the extent that the Issuing Lender has not been
         reimbursed as required hereunder or under any such Letter of Credit,
         each such Lender shall pay to the Issuing Lender its pro rata share of
         such unreimbursed drawing in same day funds on the day of notification
         by the Issuing Lender of an unreimbursed drawing pursuant to the
         provisions of subsection (d) below. The obligation of each Lender to so
         reimburse the Issuing Lender shall be absolute and unconditional and
         shall not be affected by the occurrence of a Default, an Event of
         Default or any other occurrence or event. Any such reimbursement shall
         not relieve or otherwise impair the obligation of the Borrower to
         reimburse the Issuing Lender under any Letter of Credit, together with
         interest as hereinafter provided.

                  (d)      Reimbursement. In the event of any drawing under any
         Letter of Credit, the Issuing Lender will promptly notify the Borrower.
         Unless the Borrower shall immediately


                                       29
<PAGE>   35
         notify the Issuing Lender that the Borrower intends to otherwise
         reimburse the Issuing Lender for such drawing, the Borrower shall be
         deemed to have requested that the Lenders make a Revolving Loan in the
         amount of the drawing as provided in subsection (e) below on the
         related Letter of Credit, the proceeds of which will be used to satisfy
         the related reimbursement obligations. The Borrower promises to
         reimburse the Issuing Lender on the day of drawing under any Letter of
         Credit (either with the proceeds of a Revolving Loan obtained hereunder
         or otherwise) in same day funds. If the Borrower shall fail to
         reimburse the Issuing Lender as provided hereinabove, the unreimbursed
         amount of such drawing shall bear interest at a per annum rate equal to
         the Adjusted Base Rate plus 2%. The Borrower's reimbursement
         obligations hereunder shall be absolute and unconditional under all
         circumstances irrespective of any rights of setoff, counterclaim or
         defense to payment the Borrower may claim or have against the Issuing
         Lender, the Administrative Agent, the Lenders, the beneficiary of the
         Letter of Credit drawn upon or any other Person, including, without
         limitation, any defense based on any failure of the Borrower or any
         other Credit Party to receive consideration or the legality, validity,
         regularity or unenforceability of the Letter of Credit. The Issuing
         Lender will promptly notify the other Lenders of the amount of any
         unreimbursed drawing and each Lender shall promptly pay to the
         Administrative Agent for the account of the Issuing Lender in Dollars
         and in immediately available funds, the amount of such Lender's pro
         rata share of such unreimbursed drawing. Such payment shall be made on
         the day such notice is received by such Lender from the Issuing Lender
         if such notice is received at or before 2:00 P.M. (Charlotte, North
         Carolina time); otherwise such payment shall be made at or before 12:00
         Noon (Charlotte, North Carolina time) on the Business Day next
         succeeding the day such notice is received. If such Lender does not pay
         such amount to the Issuing Lender in full upon such request, such
         Lender shall, on demand, pay to the Administrative Agent for the
         account of the Issuing Lender interest on the unpaid amount during the
         period from the date of such drawing until such Lender pays such amount
         to the Issuing Lender in full at a rate per annum equal to, if paid
         within two (2) Business Days of the date that such Lender is required
         to make payments of such amount pursuant to the preceding sentence, the
         Federal Funds Rate and thereafter at a rate equal to the Base Rate.
         Each Lender's obligation to make such payment to the Issuing Lender,
         and the right of the Issuing Lender to receive the same, shall be
         absolute and unconditional, shall not be affected by any circumstance
         whatsoever and without regard to the termination of this Credit
         Agreement or the Commitments hereunder, the existence of a Default or
         Event of Default or the acceleration of the obligations of the Borrower
         hereunder and shall be made without any offset, abatement, withholding
         or reduction whatsoever. Simultaneously with the making of each such
         payment by a Lender to the Issuing Lender, such Lender shall,
         automatically and without any further action on the part of the Issuing
         Lender or such Lender, acquire a Participation Interest in an amount
         equal to such payment (excluding the portion of such payment
         constituting interest owing to the Issuing Lender) in the related
         unreimbursed drawing portion of the LOC Obligation and in the interest
         thereon and in the related LOC Documents, and shall have a claim
         against the Borrower with respect thereto.

                  (e)      Repayment with Revolving Loans. On any day on which
         the Borrower shall have requested, or been deemed to have requested, a
         Revolving Loan advance to reimburse a drawing under a Letter of Credit,
         the Administrative Agent shall give notice to the Lenders that a
         Revolving Loan has been requested or deemed requested by the Borrower
         to be made in connection with a drawing under a Letter of Credit, in
         which case a Revolving


                                       30
<PAGE>   36
         Loan advance comprised of Base Rate Loans (or Eurodollar Loans to the
         extent the Borrower has complied with the procedures of Section
         2.1(b)(i) with respect thereto) shall be immediately made to the
         Borrower by all Lenders (notwithstanding any termination of the
         Commitments pursuant to Section 9.2) pro rata based on the respective
         Revolving Commitment Percentages of the Lenders (determined before
         giving effect to any termination of the Commitments pursuant to Section
         9.2) and the proceeds thereof shall be paid directly to the Issuing
         Lender for application to the respective LOC Obligations. Each such
         Lender hereby irrevocably agrees to make its pro rata share of each
         such Revolving Loan immediately upon any such request or deemed request
         in the amount, in the manner and on the date specified in the preceding
         sentence notwithstanding (i) the amount of such borrowing may not
         comply with the minimum amount for advances of Revolving Loans
         otherwise required hereunder, (ii) whether any conditions specified in
         Section 5.2 are then satisfied, (iii) whether a Default or an Event of
         Default then exists, (iv) failure for any such request or deemed
         request for Revolving Loan to be made by the time otherwise required
         hereunder, (v) whether the date of such borrowing is a date on which
         Revolving Loans are otherwise permitted to be made hereunder or (vi)
         any termination of the Commitments relating thereto immediately prior
         to or contemporaneously with such borrowing. In the event that any
         Revolving Loan cannot for any reason be made on the date otherwise
         required above (including, without limitation, as a result of the
         commencement of a proceeding under the Bankruptcy Code with respect to
         the Borrower or any other Credit Party), then each such Lender hereby
         agrees that it shall forthwith purchase (as of the date such borrowing
         would otherwise have occurred, but adjusted for any payments received
         from the Borrower on or after such date and prior to such purchase)
         from the Issuing Lender such Participation Interests in the outstanding
         LOC Obligations as shall be necessary to cause each such Lender to
         share in such LOC Obligations ratably (based upon the respective
         Revolving Commitment Percentages of the Lenders (determined before
         giving effect to any termination of the Commitments pursuant to Section
         9.2)), provided that at the time any purchase of Participation
         Interests pursuant to this sentence is actually made, the purchasing
         Lender shall be required to pay to the Issuing Lender, to the extent
         not paid to the Issuer by the Borrower in accordance with the terms of
         subsection (d) above, interest on the principal amount of Participation
         Interests purchased for each day from and including the day upon which
         such borrowing would otherwise have occurred to but excluding the date
         of payment for such Participation Interests, at the rate equal to, if
         paid within two (2) Business Days of the date of the Revolving Loan
         advance, the Federal Funds Rate, and thereafter at a rate equal to the
         Base Rate.

                  (f)      Designation of Consolidated Parties as Account
         Parties. Notwithstanding anything to the contrary set forth in this
         Credit Agreement, including, without limitation, Section 2.2(a), a
         Letter of Credit issued hereunder may contain a statement to the effect
         that such Letter of Credit is issued for the account of a Consolidated
         Party other than the Borrower, provided that, notwithstanding such
         statement, the Borrower shall be the actual account party for all
         purposes of this Credit Agreement for such Letter of Credit and such
         statement shall not affect the Borrower's reimbursement obligations
         hereunder with respect to such Letter of Credit.

                  (g)      Renewal, Extension. The renewal or extension of any
         Letter of Credit shall, for purposes hereof, be treated in all respects
         the same as the issuance of a new Letter of Credit hereunder.


                                       31
<PAGE>   37
                  (h)      Uniform Customs and Practices. The Issuing Lender may
         have the Letters of Credit be subject to The Uniform Customs and
         Practice for Documentary Credits, as published as of the date of issue
         by the International Chamber of Commerce (the "UCP"), in which case the
         UCP may be incorporated therein and deemed in all respects to be a part
         thereof.

                  (i)      Indemnification; Nature of Issuing Lender's Duties.

                           (i)      In addition to its other obligations under
                  this Section 2.2, the Borrower hereby agrees to pay, and
                  protect, indemnify and save each Lender harmless from and
                  against, any and all claims, demands, liabilities, damages,
                  losses, costs, charges and expenses (including reasonable
                  attorneys' fees) that such Lender may incur or be subject to
                  as a consequence, direct or indirect, of (A) the issuance of
                  any Letter of Credit or (B) the failure of such Lender to
                  honor a drawing under a Letter of Credit as a result of any
                  act or omission, whether rightful or wrongful, of any present
                  or future de jure or de facto government or Governmental
                  Authority (all such acts or omissions, herein called
                  "Government Acts").

                           (ii)     As between the Borrower and the Lenders
                  (including the Issuing Lender), the Borrower shall assume all
                  risks of the acts, omissions or misuse of any Letter of Credit
                  by the beneficiary thereof. No Lender (including the Issuing
                  Lender) shall be responsible: (A) for the form, validity,
                  sufficiency, accuracy, genuineness or legal effect of any
                  document submitted by any party in connection with the
                  application for and issuance of any Letter of Credit, even if
                  it should in fact prove to be in any or all respects invalid,
                  insufficient, inaccurate, fraudulent or forged; (B) for the
                  validity or sufficiency of any instrument transferring or
                  assigning or purporting to transfer or assign any Letter of
                  Credit or the rights or benefits thereunder or proceeds
                  thereof, in whole or in part, that may prove to be invalid or
                  ineffective for any reason; (C) for errors, omissions,
                  interruptions or delays in transmission or delivery of any
                  messages, by mail, cable, telegraph, telex or otherwise,
                  whether or not they be in cipher; (D) for any loss or delay in
                  the transmission or otherwise of any document required in
                  order to make a drawing under a Letter of Credit or of the
                  proceeds thereof; and (E) for any consequences arising from
                  causes beyond the control of such Lender, including, without
                  limitation, any Government Acts. None of the above shall
                  affect, impair, or prevent the vesting of the Issuing Lender's
                  rights or powers hereunder.

                           (iii)    In furtherance and extension and not in
                  limitation of the specific provisions hereinabove set forth,
                  any action taken or omitted by any Lender (including the
                  Issuing Lender), under or in connection with any Letter of
                  Credit or the related certificates, if taken or omitted in
                  good faith, shall not put such Lender under any resulting
                  liability to the Borrower or any other Credit Party. It is the
                  intention of the parties that this Credit Agreement shall be
                  construed and applied to protect and indemnify each Lender
                  (including the Issuing Lender) against any and all risks
                  involved in the issuance of the Letters of Credit, all of
                  which risks are hereby assumed by the Borrower (on behalf of
                  itself and each of the other Credit Parties), including,
                  without limitation, any and all Government Acts. No Lender


                                       32
<PAGE>   38
                  (including the Issuing Lender) shall, in any way, be liable
                  for any failure by such Lender or anyone else to pay any
                  drawing under any Letter of Credit as a result of any
                  Government Acts or any other cause beyond the control of such
                  Lender.

                           (iv)     Nothing in this subsection (i) is intended
                  to limit the reimbursement obligations of the Borrower
                  contained in subsection (d) above. The obligations of the
                  Borrower under this subsection (i) shall survive the
                  termination of this Credit Agreement. No act or omission of
                  any current or prior beneficiary of a Letter of Credit shall
                  in any way affect or impair the rights of the Lenders
                  (including the Issuing Lender) to enforce any right, power or
                  benefit under this Credit Agreement.

                           (v)      Notwithstanding anything to the contrary
                  contained in this subsection (i), the Borrower shall have no
                  obligation to indemnify any Lender (including the Issuing
                  Lender) in respect of any liability incurred by such Lender
                  (A) arising solely out of the gross negligence or willful
                  misconduct of such Lender, as determined by a court of
                  competent jurisdiction, or (B) caused by such Lender's failure
                  to pay under any Letter of Credit after presentation to it of
                  a request strictly complying with the terms and conditions of
                  such Letter of Credit, as determined by a court of competent
                  jurisdiction, unless such payment is prohibited by any law,
                  regulation, court order or decree.

                  (j)      Responsibility of Issuing Lender. It is expressly
         understood and agreed that the obligations of the Issuing Lender
         hereunder to the Lenders are only those expressly set forth in this
         Credit Agreement and that the Issuing Lender shall be entitled to
         assume that the conditions precedent set forth in Section 5.2 have been
         satisfied unless it shall have acquired actual knowledge that any such
         condition precedent has not been satisfied; provided, however, that
         nothing set forth in this Section 2.2 shall be deemed to prejudice the
         right of any Lender to recover from the Issuing Lender any amounts made
         available by such Lender to the Issuing Lender pursuant to this Section
         2.2 in the event that it is determined by a court of competent
         jurisdiction that the payment with respect to a Letter of Credit
         constituted gross negligence or willful misconduct on the part of the
         Issuing Lender.

                  (k)      Conflict with LOC Documents. In the event of any
         conflict between this Credit Agreement and any LOC Document (including

         2.3      SWINGLINE LOAN SUBFACILITY OF THE REVOLVER.

                  (a)      Swingline Commitment. Subject to the terms and
         conditions hereof and in reliance upon the representations and
         warranties set forth herein, the Swingline Lender, in its individual
         capacity, agrees to make certain revolving credit loans requested by
         the Borrower in Dollars to the Borrower (each a "Swingline Loan" and,
         collectively, the "Swingline Loans") from time to time from the Closing
         Date until the Maturity Date for the purposes hereinafter set forth;
         provided, however, (i) the aggregate principal amount of Swingline
         Loans outstanding at any time shall not exceed TWO MILLION DOLLARS
         ($2,000,000) (the "Swingline Committed Amount"), and (ii) the sum of
         the aggregate outstanding principal amount of Revolving Loans plus LOC
         Obligations plus Swingline Loans shall not exceed the Revolving
         Committed Amount. Swingline Loans hereunder


                                       33
<PAGE>   39
         shall be made as Base Rate Loans and may be repaid and reborrowed in
         accordance with the provisions hereof.

                  (b)      Swingline Loan Advances.

                           (i)      Notices; Disbursement. Whenever the Borrower
                  desires a Swingline Loan advance hereunder it shall give
                  written notice (or telephonic notice promptly confirmed in
                  writing) to the Swingline Lender not later than 3:00 P.M.
                  (Charlotte, North Carolina time) on the Business Day of the
                  requested Swingline Loan advance. Each such notice shall be
                  irrevocable and shall specify (A) that a Swingline Loan
                  advance is requested, (B) the date of the requested Swingline
                  Loan advance (which shall be a Business Day) and (C) the
                  principal amount of the Swingline Loan advance requested. Each
                  Swingline Loan shall be made as a Base Rate Loan and shall
                  have such maturity date as the Swingline Lender and the
                  Borrower shall agree upon receipt by the Swingline Lender of
                  any such notice from the Borrower. The Swingline Lender shall
                  initiate the transfer of funds representing the Swingline Loan
                  advance to the Borrower by 3:00 P.M. (Charlotte, North
                  Carolina time) on the Business Day of the requested borrowing.

                           (ii)     Minimum Amounts. Each Swingline Loan advance
                  shall be in a minimum principal amount of $100,000 and
                  integral multiples of $50,000 (or the remaining amount of the
                  Swingline Committed Amount, if less).

                           (iii)    Repayment of Swingline Loans. The principal
                  amount of all Swingline Loans shall be due and payable on the
                  earlier of (A) the maturity date agreed to by the Swingline
                  Lender and the Borrower with respect to such Loan (which
                  maturity date shall not be a date more than seven (7) Business
                  Days from the date of advance thereof) or (B) the Maturity
                  Date. The Swingline Lender may, at any time, in its sole
                  discretion, by written notice to the Borrower and the Lenders,
                  demand repayment of its Swingline Loans by way of a Revolving
                  Loan advance, in which case the Borrower shall be deemed to
                  have requested a Revolving Loan advance comprised solely of
                  Base Rate Loans in the amount of such Swingline Loans;
                  provided, however, that any such demand shall be deemed to
                  have been given one Business Day prior to the Maturity Date
                  and on the date of the occurrence of any Event of Default
                  described in Section 9.1 and upon acceleration of the
                  indebtedness hereunder and the exercise of remedies in
                  accordance with the provisions of Section 9.2. Each Lender
                  hereby irrevocably agrees to make its pro rata share of each
                  such Revolving Loan in the amount, in the manner and on the
                  date specified in the preceding sentence notwithstanding (I)
                  the amount of such borrowing may not comply with the minimum
                  amount for advances of Revolving Loans otherwise required
                  hereunder, (II) whether any conditions specified in Section
                  5.2 are then satisfied, (III) whether a Default or an Event of
                  Default then exists, (IV) failure of any such request or
                  deemed request for Revolving Loan to be made by the time
                  otherwise required hereunder, (V) whether the date of such
                  borrowing is a date on which Revolving Loans are otherwise
                  permitted to be made hereunder or (VI) any termination of the
                  Commitments relating thereto immediately prior to or
                  contemporaneously with such borrowing. In the event that any
                  Revolving Loan cannot for any reason be made on the date
                  otherwise required


                                       34

                  above (including, without limitation, as a result of the
                  commencement of a proceeding under the Bankruptcy Code with
                  respect to the Borrower or any other Credit Party), then each
                  Lender hereby agrees that it shall forthwith purchase (as of
                  the date such borrowing would otherwise have occurred, but
                  adjusted for any payments received from the Borrower on or
                  after such date and prior to such purchase) from the Swingline
                  Lender such Participation Interests in the outstanding
                  Swingline Loans as shall be necessary to cause each such
                  Lender to share in such Swingline Loans ratably based upon its
                  Revolving Commitment Percentage of the Revolving Committed
                  Amount (determined before giving effect to any termination of
                  the Commitments pursuant to Section 3.4), provided that (A)
                  all interest payable on the Swingline Loans shall be for the
                  account of the Swingline Lender until the date as of which the
                  respective Participation Interest is purchased and (B) at the
                  time any purchase of Participation Interests pursuant to this
                  sentence is actually made, the purchasing Lender shall be
                  required to pay to the Swingline Lender, to the extent not
                  paid to the Swingline Lender by the Borrower in accordance
                  with the terms of subsection (c)(ii) below, interest on the
                  principal amount of Participation Interests purchased for each
                  day from and including the day upon which such borrowing would
                  otherwise have occurred to but excluding the date of payment
                  for such Participation Interests, at the rate equal to the
                  Federal Funds Rate.

                  (c)      Interest on Swingline Loans.

                           (i)      Rate of Interest . Subject to the provisions
                  of Section 3.1, each Swingline Loan shall bear interest at a
                  per annum rate equal to the Adjusted Base Rate for Revolving
                  Loans.

                           (ii)     Payment of Interest. Interest on Swingline
                  Loans shall be payable in arrears on each applicable Interest
                  Payment Date (or at such other times as may be specified
                  herein), unless accelerated sooner pursuant to Section 9.2.

                  (d)      Swingline Note. The Swingline Loans shall be
         evidenced by a duly executed promissory note of the Borrower to the
         Swingline Lender in an original principal amount equal to the Swingline
         Committed Amount substantially in the form of Exhibit 2.3(d).

         2.4      TRANCHE A TERM LOAN.

                  (a)      Tranche A Term Commitment. Subject to the terms and
         conditions hereof and in reliance upon the representations and
         warranties set forth herein, each Lender severally agrees to make
         available to the Borrower on the Closing Date such Lender's Tranche A
         Term Loan Commitment Percentage of a term loan in Dollars (the "Tranche
         A Term Loan") in the aggregate principal amount of FORTY-FIVE MILLION
         DOLLARS ($45,000,000) (the "Tranche A Term Loan Committed Amount"). The
         Tranche A Term Loan may consist of Base Rate Loans or Eurodollar Loans,
         or a combination thereof, as the Borrower may request; provided,
         however, that no more than 5 Eurodollar Loans shall be outstanding
         hereunder at any time (it being understood that, for purposes hereof,
         Eurodollar Loans with different Interest Periods shall be considered as
         separate Eurodollar Loans, even if they begin on the same date,
         although borrowings, extensions and conversions may, in


                                       35
<PAGE>   41
         accordance with the provisions hereof, be combined at the end of
         existing Interest Periods to constitute a new Eurodollar Loan with a
         single Interest Period). Amounts repaid on the Tranche A Term Loan may
         not be reborrowed.

                  (b)      Borrowing Procedures. The Borrower shall submit an
         appropriate Notice of Borrowing to the Administrative Agent not later
         than 1:00 P.M. (Charlotte, North Carolina time) on the Closing Date,
         with respect to the portion of the Tranche A Term Loan initially
         consisting of a Base Rate Loan, or on the third Business Day prior to
         the Closing Date, with respect to the portion of the Tranche A Term
         Loan initially consisting of one or more Eurodollar Loans, which Notice
         of Borrowing shall be irrevocable and shall specify (i) that the
         funding of a Tranche A Term Loan is requested and (ii) whether the
         funding of the Tranche A Term Loan shall be comprised of Base Rate
         Loans, Eurodollar Loans or a combination thereof, and if Eurodollar
         Loans are requested, the Interest Period(s) therefor. If the Borrower
         shall fail to deliver such Notice of Borrowing to the Administrative
         Agent by 1:00 P.M. (Charlotte, North Carolina time) on the third
         Business Day prior to the Closing Date, then the full amount of the
         Tranche A Term Loan shall be disbursed on the Closing Date as a
         Eurodollar Loan with a period ending March 31, 1999. Each Lender shall
         make its Tranche A Term Loan Commitment Percentage of the Tranche A
         Term Loan available to the Administrative Agent for the account of the
         Borrower at the office of the Administrative Agent specified in
         Schedule 2.1(a), or at such other office as the Administrative Agent
         may designate in writing, by 1:00 P.M. (Charlotte, North Carolina time)
         on the Closing Date in Dollars and in funds immediately available to
         the Administrative Agent.

                  (c)      Minimum Amounts. Each Eurodollar Loan or Base Rate
         Loan that is part of the Tranche A Term Loan shall be in an aggregate
         principal amount that is not less than $1,000,000 and integral
         multiples of $250,000 in excess thereof (or the then remaining
         principal balance of the Tranche A Term Loan, if less).

                  (d)      Repayment of Tranche A Term Loan. The principal
         amount of the Tranche A Term Loan shall be repaid in twenty (20)
         consecutive quarterly installments as follows, unless accelerated
         sooner pursuant to Section 9.2:

                  (e)      Interest. Subject to the provisions of Section 3.1,
         the Tranche A Term Loan shall bear interest at a per annum rate equal
         to:

                           (i)      Base Rate Loans. During such periods as the
                  Tranche A Term Loan shall be comprised in whole or in part of
                  Base Rate Loans, such Base Rate Loans shall bear interest at a
                  per annum rate equal to the Adjusted Base Rate.

                           (ii)     Eurodollar Loans. During such periods as the
                  Tranche A Term Loan shall be comprised in whole or in part of

         specified herein).

                  (f)      Tranche A Term Notes. The portion of the Tranche A
         Term Loan made by each Lender shall be evidenced by a duly executed
         promissory note of the Borrower to such Lender in an original principal

         2.5      DELAYED DRAW TERM LOAN.

                  (a)      Delayed Draw Term Commitment. Subject to the terms
         and conditions hereof and in reliance upon the representations and
         warranties set forth herein, each Lender severally agrees to make
         available to the Borrower from time to time from the Closing Date until
         the second anniversary of the Closing Date, or such earlier date as the
         Delayed Draw Term Loan Commitments shall have been terminated as
         provided herein, such Lender's Delayed Draw Term Loan Commitment
         Percentage of a term loan in Dollars (the "Delayed Draw Term Loan") in
         the aggregate principal amount of up to TWENTY-FIVE MILLION DOLLARS
         ($25,000,000) (the "Delayed Draw Term Loan Committed Amount"). The
         Delayed Draw Term Loan may consist of Base Rate Loans or Eurodollar
         Loans, or a combination thereof, as the Borrower may request; provided,
         however, that no more than 5 Eurodollar Loans shall be outstanding
         hereunder at any time (it being understood that, for purposes hereof,
         Eurodollar Loans with different Interest Periods shall be considered as
         separate Eurodollar Loans, even if they begin on the same date,
         although borrowings, extensions and conversions may, in accordance with
         the provisions hereof, be combined at the end of existing Interest
         Periods to constitute a new Eurodollar Loan with a single Interest
         Period). Amounts repaid on the Delayed Draw Term Loan may not be
         reborrowed. The proceeds of the Delayed Draw Term Loan may only be used
         to finance Permitted Acquisitions.

                  (b)      Borrowing Procedures. The Borrower shall request the
         full amount of the Delayed Draw Term Loan or a portion thereof by
         written notice (or telephonic notice promptly confirmed in writing) to
         the Administrative Agent not later than 1:00 P.M. (Charlotte, North
         Carolina time) on the Business Day prior to the date of the requested
         borrowing in the case of Base Rate Loans, and on the third Business Day
         prior to the date of the requested borrowing in the case of Eurodollar
         Loans. Each such request for borrowing shall be irrevocable and shall
         specify (i) that the funding of a Delayed Draw Term Loan is requested,
         (ii) the date of the requested borrowing (which shall be a Business
         Day), (iii) the aggregate principal amount to be borrowed, and (iv)
         whether the funding of the Delayed Draw Term Loan shall be comprised of
         Base Rate Loans, Eurodollar Loans or a combination thereof, and if
         Eurodollar Loans are requested, the Interest Period(s) therefor. If the
         Borrower shall fail to specify in any such Notice of Borrowing (I) an
         applicable Interest Period in the case of a Eurodollar Loan, then such
         notice shall be deemed to be a request for an Interest Period of one
         month, or (II) the type of Delayed Draw Term Loan requested, then such
         notice shall be deemed to be a request for a Base Rate Loan hereunder.
         The Administrative Agent shall give notice to each affected Lender
         promptly upon receipt of each Notice of Borrowing pursuant to this
         Section 2.5(b), the contents thereof and each such Lender's share of
         any borrowing to be made pursuant thereto. Each Lender shall make its
         Delayed Draw Term Loan Commitment Percentage of the Delayed Draw Term
         Loan available to the Administrative Agent for the account of the

         the Delayed Draw Term Loan shall bear interest at a per annum rate
         equal to:

                           (i)      Base Rate Loans. During such periods as the
                  Delayed Draw Term Loan shall be comprised in whole or in part
                  of Base Rate Loans, such Base Rate Loans shall bear interest
                  at a per annum rate equal to the Adjusted Base Rate.

                           (ii)     Eurodollar Loans. During such periods as the
                  Delayed Draw Term Loan shall be comprised in whole or in part
                  of Eurodollar Loans, such Eurodollar Loans shall bear interest
                  at a per annum rate equal to the Adjusted Eurodollar Rate.

         Interest on the Delayed Draw Term Loan shall be payable in arrears on
         each applicable Interest Payment Date (or at such other times as may be
         specified herein).

                  (f)      Delayed Draw Term Notes. The portion of the Delayed
         Draw Term Loan made by each Lender shall be evidenced by a duly
         executed promissory note of the


                                       39
<PAGE>   45
         Borrower to such Lender in an original principal amount equal to such
         Lender's Delayed Draw Term Loan Commitment Percentage of the Delayed
         Draw Term Loan and substantially in the form of Exhibit 2.4(f).


                                    SECTION 3

                 OTHER PROVISIONS RELATING TO CREDIT FACILITIES

         3.1      DEFAULT RATE.

         Upon the occurrence, and during the continuance, of an Event of
Default, (i) the principal of and, to the extent permitted by law, interest on
the Loans and any other amounts owing hereunder or under the other Credit
Documents shall bear interest, payable on demand, at a per annum rate 2% greater
than the rate which would otherwise be applicable (or if no rate is applicable,
whether in respect of interest, fees or other amounts, then the Adjusted Base
Rate plus 2%) and (ii) the Letter of Credit Fee and the Trade Letter of Credit
shall accrue at a per annum rate 2% greater than the rate which would otherwise
be applicable.

         3.2      EXTENSION AND CONVERSION.

         The Borrower shall have the option, on any Business Day, to extend
existing Loans into a subsequent permissible Interest Period or to convert Loans
into Loans of another interest rate type; provided, however, that (i) except as
provided in Section 3.8, Eurodollar Loans may be converted into Base Rate Loans
or extended as Eurodollar Loans for new Interest Periods only on the last day of
the Interest Period applicable thereto, (ii) without the consent of the Required
Lenders, Eurodollar Loans may be extended, and Base Rate Loans may be converted
into Eurodollar Loans, only if the conditions precedent set forth in Section 5.2
are satisfied on the date of extension or conversion, (iii) Loans extended as,
or converted into, Eurodollar Loans shall be subject to the terms of the
definition of "Interest Period" set forth in Section 1.1 and shall be in such
minimum amounts as provided in, with respect to Revolving Loans, Section
2.1(b)(ii), with respect to the Tranche A Term Loan, Section 2.4(c), or, with
respect to the Delayed Draw Term Loan, Section 2.5(c), (iv) no more than 10
Eurodollar Loans shall be outstanding hereunder at any time (it being understood
that, for purposes hereof, Eurodollar Loans with different Interest Periods
shall be considered as separate Eurodollar Loans, even if they begin on the same
date, although borrowings, extensions and conversions may, in accordance with
the provisions hereof, be combined at the end of existing Interest Periods to
constitute a new Eurodollar Loan with a single Interest Period), (v) any request
for extension or conversion of a Eurodollar Loan which shall fail to specify an
Interest Period shall be deemed to be a request for an Interest Period of one
month and (vi) Swingline Loans may not be extended or converted pursuant to this
Section 3.2. Each such extension or conversion shall be effected by the Borrower
by giving a Notice of Extension/Conversion (or telephonic notice promptly
confirmed in writing) to the office of the Administrative Agent specified in
Schedule 2.1(a), or at such other office as the Administrative Agent may
designate in writing, prior to 1:00 P.M. (Charlotte, North Carolina time) on the
Business Day of, in the case of the conversion of a Eurodollar Loan into a Base
Rate Loan, and on the third Business Day prior to, in the case of the extension
of a Eurodollar Loan as, or conversion of a Base Rate Loan into, a Eurodollar
Loan, the date of the proposed extension or conversion, specifying the date of
the proposed extension or conversion, the Loans to be so extended or converted,
the types of Loans into which such Loans are


                                       40
<PAGE>   46
to be converted and, if appropriate, the applicable Interest Periods with
respect thereto. Each request for extension or conversion shall be irrevocable
and shall constitute a representation and warranty by the Borrower of the
matters specified in subsections (b), (c), (d), (e) and (f) of Section 5.2. In
the event the Borrower fails to request an extension or conversion of any
Eurodollar Loan in accordance with this Section, then such Eurodollar Loan shall
be automatically converted into a Eurodollar Loan with a period of one month's
duration at the end of the Interest Period applicable thereto. If any such
conversion or extension is not permitted or required by this Section, then such
Eurodollar Loan shall be automatically converted into a Base Rate Loan at the
end of the Interest Period applicable thereto. The Administrative Agent shall
give each Lender notice as promptly as practicable of any such proposed
extension or conversion affecting any Loan.

         3.3      PREPAYMENTS.

                  (a)      Voluntary Prepayments. The Borrower shall have the
         right to prepay Loans in whole or in part from time to time; provided,
         however, that each partial prepayment of Loans (other than Swingline
         Loans) shall be in a minimum principal amount of $1,000,000 and
         integral multiples of $250,000 in excess thereof (or the then remaining
         principal balance of the Revolving Loans, the Tranche A Term Loan or
         the Delayed Draw Term Loan, as applicable, if less). Subject to the
         foregoing terms, amounts prepaid under this Section 3.3(a) shall be
         applied as the Borrower may elect; provided that if the Borrower fails
         to specify a voluntary prepayment then such prepayment shall be applied
         first to Revolving Loans and then ratably to the Tranche A Term Loan
         and the Delayed Draw Term Loan (in each case ratably to the remaining
         Principal Amortization Payments thereof), in each case first to Base
         Rate Loans and then to Eurodollar Loans in direct order of Interest
         Period maturities. All prepayments under this Section 3.3(a) shall be
         subject to Section 3.12, but otherwise without premium or penalty, and
         be accompanied by interest on the principal amount prepaid through the
         date of prepayment.

                  (b)      Mandatory Prepayments.

                           (i)      (A)      Revolving Committed Amount. If at
                           any time, the sum of the aggregate outstanding
                           principal amount of Revolving Loans plus LOC
                           Obligations plus Swingline Loans shall exceed the
                           Revolving Committed Amount, the Borrower immediately
                           shall prepay the Revolving Loans and (after all
                           Revolving Loans have been repaid) cash collateralize
                           the LOC Obligations, in an amount sufficient to
                           eliminate such excess (such prepayment to be applied
                           as set forth in clause (v) below).

                                    (B)      LOC Committed Amount. If at any
                           time, the sum of the aggregate principal amount of
                           LOC Obligations shall exceed the LOC Committed
                           Amount, the Borrower immediately shall cash
                           collateralize the LOC Obligations in an amount
                           sufficient to eliminate such excess (such prepayment
                           to be applied as set forth in clause (v) below).

                           (ii)     (A)      Asset Dispositions. Immediately
                           upon the occurrence of any Asset Disposition
                           Prepayment Event, the Borrower shall prepay the Loans
                           in an aggregate amount equal to 100% of the Net Cash
                           Proceeds of the related Asset Disposition not applied
                           (or caused to be applied) by the Credit

                           Eligible Reinvestments as contemplated by the terms
                           of Section 8.5(f) (such prepayment to be applied as
                           set forth in clause (v) below).

                                    (B)      Casualty and Condemnation Events.
                           Immediately upon the occurrence of any event
                           requiring application of any insurance proceeds to
                           the prepayment of Loans (and cash collateralization
                           of LOC Obligations) pursuant to Section 7.6(d), the
                           Borrower shall prepay the Loans in the amount
                           required by such Section 7.6(d) (such prepayment to
                           be applied as set forth in clause (v) below).

                           (iii)    Debt Issuances. Immediately upon receipt by
                  any Consolidated Party of proceeds from any Debt Issuance
                  other than a Excluded Debt Issuance, the Borrower shall prepay
                  the Loans in an aggregate amount equal to 100% of the Net Cash
                  Proceeds of such Debt Issuance to the Lenders (such prepayment
                  to be applied as set forth in clause (v) below).

                           (iv)     Issuances of Equity. Immediately upon
                  receipt by a Consolidated Party of proceeds from any Equity
                  Issuance (other than an Excluded Equity Issuance), the
                  Borrower shall prepay the Loans in an aggregate amount equal
                  to 50% of the Net Cash Proceeds of such Equity Issuance to the
                  Lenders (such prepayment to be applied as set forth in clause
                  (v) below).

                           (v)      Application of Mandatory Prepayments. All
                  amounts required to be paid pursuant to this Section 3.3(b)

         3.4      TERMINATION AND REDUCTION OF REVOLVING COMMITTED AMOUNT.

                  (a)      Voluntary Reductions. The Borrower may from time to
         time permanently reduce or terminate the Revolving Committed Amount in
         whole or in part (in minimum aggregate amounts of $2,000,000 and
         integral multiples of $1,000,000 in excess thereof (or, if less, the
         full remaining amount of the then applicable Revolving Committed
         Amount)) upon five Business Days' prior written notice to the
         Administrative Agent; provided, however, no such termination or
         reduction shall be made which would cause the sum of the aggregate
         outstanding principal amount of Revolving Loans plus LOC Obligations
         plus Swingline Loans to exceed the Revolving Committed Amount, unless,
         concurrently with such termination or reduction, the Revolving Loans
         are repaid to the extent necessary to eliminate such excess. The
         Administrative Agent shall promptly notify each affected Lender of
         receipt by the Administrative Agent of any notice from the Borrower
         pursuant to this Section 3.4(a).

                  (b)      Mandatory Reductions. On any date that the Revolving
         Loans are required to be prepaid pursuant to the terms of Section
         3.3(b)(v), the Revolving Committed Amount automatically shall be
         permanently reduced by the amount of such required prepayment and/or
         reduction.

                  (c)      Maturity Date. The Revolving Commitments of the
         Lenders, the LOC Commitment of the Issuing Lender and the Swingline
         Commitment of the Swingline Lender shall automatically terminate on the
         Maturity Date.

                  (d)      General. The Borrower shall pay to the Administrative
         Agent for the account of the Lenders in accordance with the terms of
         Section 3.5(b)(i), on the date of each termination or reduction of the
         Revolving Committed Amount, the Revolving Unused Fee accrued through
         the date of such termination or reduction on the amount of the
         Revolving Committed Amount so terminated or reduced.

         3.5      FEES.

                  (a)      Upfront Fees. The Borrower agrees to pay to
         NationsBank in immediately available funds on or before the Closing
         Date an upfront fee (the "Upfront Fee") in the amount provided in the
         Administrative Agent's Fee Letter.

                  (b)      Unused Fee.

                           (i)      In consideration of the Revolving
                  Commitments of the Lenders hereunder, the Borrower agrees to
                  pay to the Administrative Agent for the account of each Lender
                  a fee (the "Revolving Unused Fee") on the Unused Revolving
                  Committed Amount computed at a per annum rate for each day
                  during the applicable Revolving Unused Fee Calculation Period
                  (hereinafter defined) at a rate equal to the Applicable
                  Percentage in effect from time to time. The Revolving Unused
                  Fee shall commence to accrue on the Closing Date and shall be
                  due and payable in arrears on the last Business Day of each
                  March, June, September and December (and any date that the
                  Revolving Committed Amount is reduced as provided in Section
                  3.4(a) and the Maturity Date) for the immediately preceding

                  quarter (or portion thereof) (each such quarter or portion
                  thereof for which the Revolving Unused Fee is payable
                  hereunder being herein referred to as a "Revolving Unused Fee
                  Calculation Period"), beginning with the first of such dates
                  to occur after the Closing Date.

                           (ii)     In consideration of the Delayed Draw Term
                  Loan Commitments of the Lenders hereunder, the Borrower agrees
                  to pay to the Administrative Agent for the account of each
                  Lender a fee (the "Delayed Draw Unused Fee") on the Unused
                  Delayed Draw Term Loan Committed Amount computed at a per
                  annum rate for each day during the applicable Delayed Draw
                  Unused Fee Calculation Period (hereinafter defined) at a rate
                  equal to the Applicable Percentage in effect from time to
                  time. The Delayed Draw Unused Fee shall commence to accrue on
                  the Closing Date and shall be due and payable in arrears on
                  the last Business Day of each March, June, September and
                  December for the immediately preceding quarter (or portion
                  thereof) (each such quarter or portion thereof for which the
                  Delayed Draw Unused Fee is payable hereunder being herein
                  referred to as a "Delayed Draw Unused Fee Calculation
                  Period"), beginning with the first of such dates to occur
                  after the Closing Date and ending with the first of such dates
                  to occur after the second anniversary of the Closing Date.

                  (c)      Letter of Credit Fees.

                           (i)      Standby Letter of Credit Issuance Fee. In
                  consideration of the issuance of standby Letters of Credit
                  hereunder, the Borrower promises to pay to the Administrative
                  Agent for the account of each Lender a fee (the "Standby
                  Letter of Credit Fee") on such Lender's Revolving Commitment
                  Percentage of the average daily maximum amount available to be
                  drawn under each such standby Letter of Credit computed at a
                  per annum rate for each day from the date of issuance to the
                  date of expiration equal to the Applicable Percentage. The
                  Standby Letter of Credit Fee will be payable quarterly in
                  arrears on the last Business Day of each March, June,
                  September and December for the immediately preceding quarter
                  (or a portion thereof).

                           (ii)     Trade Letter of Credit Drawing Fee. In
                  consideration of the issuance of trade Letters of Credit
                  hereunder, the Borrower promises to pay to the Administrative
                  Agent for the account of each Lender a fee (the "Trade Letter
                  of Credit Fee") equal to one-half (1/2) of the Standby Letter
                  of Credit Fee. The Trade Letter of Credit Fee will be payable
                  quarterly in arrears on the last Business Day of each March,
                  June, September and December for the immediately preceding
                  quarter (or a portion thereof).

                           (iii)    Issuing Lender Fees. In addition to the
                  Standby Letter of Credit Fee payable pursuant to clause (i)
                  above and the Trade Letter of Credit Fee payable pursuant to
                  clause (ii) above, the Borrower promises to pay to the
                  Administrative Agent for the account of each applicable
                  Issuing Lender without sharing by the other Lenders (i) a
                  letter of credit fronting fee of 0.25% on the average daily
                  maximum amount available to be drawn under each standby Letter
                  of Credit issued by such Issuing Lender computed at a per
                  annum rate for each day from the date of


                                       44
<PAGE>   50
                  issuance to the date of expiration and (ii) the customary
                  charges from time to time of the Issuing Lender with respect
                  to the issuance, amendment, transfer, administration,
                  cancellation and conversion of, and drawings under, such
                  Letters of Credit (collectively, the "Issuing Lender Fees").
                  The Issuing Lender Fee will be payable quarterly in arrears on
                  the last Business Day of each March, June, September and
                  December for the immediately preceding quarter (or a portion
                  thereof).

                  (d)      Administrative Fees. The Borrower agrees to pay to
         the Administrative Agent, for its own account, for the account of the
         Issuing Lender and for the account of NationsBanc Montgomery Securities
         LLC, as applicable, the fees referred to in the Administrative Agent's
         Fee Letter (collectively, the "Administrative Agent's Fees").

         3.6      CAPITAL ADEQUACY.

         If any Lender has determined, after the date hereof, that the adoption
or the becoming effective of, or any change in, or any change by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof in the interpretation or administration
of, any applicable law, rule or regulation regarding capital adequacy, or
compliance by such Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's capital or assets as a consequence of its commitments or
obligations hereunder to a level below that which such Lender could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's policies with respect to capital adequacy), then,
upon notice from such Lender to the Borrower, the Borrower shall be obligated to
pay to such Lender such additional amount or amounts as will compensate such
Lender for such reduction. Each determination by any such Lender of amounts
owing under this Section shall, absent manifest error, be conclusive and binding
on the parties hereto.

         3.7      LIMITATION ON EURODOLLAR LOANS.

         If on or prior to the first day of any Interest Period for any
Eurodollar Loan:

                  (a)      the Administrative Agent determines (which
         determination shall be conclusive) that by reason of circumstances
         affecting the relevant market, adequate and reasonable means do not
         exist for ascertaining the Eurodollar Rate for such Interest Period; or

                  (b)      the Required Lenders determine (which determination
         shall be conclusive) and notify the Administrative Agent that the
         Eurodollar Rate will not adequately and fairly reflect the cost to the
         Lenders of funding Eurodollar Loans for such Interest Period;

then the Administrative Agent shall give the Borrower prompt notice thereof, and
so long as such condition remains in effect, the Lenders shall be under no
obligation to make additional Eurodollar Loans, Continue Eurodollar Loans, or to
Convert Base Rate Loans into Eurodollar Loans and the Borrower shall, on the
last day(s) of the then current Interest Period(s) for the outstanding


                                       45
<PAGE>   51
Eurodollar Loans, either repay such Eurodollar Loans or Convert such Eurodollar
Loans into Base Rate Loans in accordance with the terms of this Credit
Agreement.

         3.8      ILLEGALITY.

         Notwithstanding any other provision of this Credit Agreement, in the
event that it becomes unlawful for any Lender or its Applicable Lending Office
to make, maintain, or fund Eurodollar Loans hereunder, then such Lender shall
promptly notify the Borrower thereof and such Lender's obligation to make or
Continue Eurodollar Loans and to Convert Base Rate Loans into Eurodollar Loans
shall be suspended until such time as such Lender may again make, maintain, and
fund Eurodollar Loans (in which case the provisions of Section 3.10 shall be
applicable).

         3.9      REQUIREMENTS OF LAW.

         If, after the date hereof, the adoption of any applicable law, rule, or
regulation, or any change in any applicable law, rule, or regulation, or any
change in the interpretation or administration thereof by any Governmental
Authority, central bank, or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such Governmental Authority, central bank, or comparable agency:

                           (i)      shall subject such Lender (or its Applicable
                  Lending Office) to any tax, duty, or other charge with respect
                  to any Eurodollar Loans, its Notes, or its obligation to make
                  Eurodollar Loans, or change the basis of taxation of any
                  amounts payable to such Lender (or its Applicable Lending
                  Office) under this Credit Agreement or its Notes in respect of
                  any Eurodollar Loans (other than taxes imposed on the overall
                  net income of such Lender by the jurisdiction in which such
                  Lender has its principal office or such Applicable Lending
                  Office);

                           (ii)     shall impose, modify, or deem applicable any
                  reserve, special deposit, assessment, or similar requirement
                  (other than the Eurodollar Reserve Requirement utilized in the
                  determination of the Adjusted Eurodollar Rate) relating to any
                  extensions of credit or other assets of, or any deposits with
                  or other liabilities or commitments of, such Lender (or its
                  Applicable Lending Office), including the Commitment of such
                  Lender hereunder; or

                           (iii)    shall impose on such Lender (or its
                  Applicable Lending Office) or the London interbank market any
                  other condition affecting this Credit Agreement or its Notes
                  or any of such extensions of credit or liabilities or
                  commitments;

and the result of any of the foregoing is to increase the cost to such Lender
(or its Applicable Lending Office) of making, Converting into, Continuing, or
maintaining any Eurodollar Loans or to reduce any sum received or receivable by
such Lender (or its Applicable Lending Office) under this Credit Agreement or
its Notes with respect to any Eurodollar Loans, then the Borrower shall pay to
such Lender on demand such amount or amounts as will compensate such Lender for
such increased cost or reduction. If any Lender requests compensation by the
Borrower under this Section 3.9, the Borrower may, by notice to such Lender
(with a copy to the Administrative Agent), suspend the obligation of such Lender
to make or Continue Eurodollar Loans, or to Convert Base


                                       46
<PAGE>   52
Rate Loans into Eurodollar Loans, until the event or condition giving rise to
such request ceases to be in effect (in which case the provisions of Section
3.10 shall be applicable); provided that such suspension shall not affect the
right of such Lender to receive the compensation so requested. Each Lender shall
promptly notify the Borrower and the Administrative Agent of any event of which
it has knowledge, occurring after the date hereof, which will entitle such
Lender to compensation pursuant to this Section 3.9 and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Lender, be otherwise disadvantageous to it. Any Lender claiming compensation
under this Section 3.9 shall furnish to the Borrower and the Administrative
Agent a statement setting forth the additional amount or amounts to be paid to
it hereunder which shall be conclusive in the absence of manifest error. In
determining such amount, such Lender may use any reasonable averaging and
attribution methods.

         3.10     TREATMENT OF AFFECTED LOANS.

         If the obligation of any Lender to make any Eurodollar Loan or to
Continue, or to Convert Base Rate Loans into, Eurodollar Loans shall be
suspended pursuant to Section 3.7, 3.8 or 3.9 hereof, such Lender's Eurodollar
Loans shall be automatically Converted into Base Rate Loans (unless repaid by
the Borrower) on the last day(s) of the then current Interest Period(s) for such
Eurodollar Loans (or, in the case of a Conversion required by Section 3.8
hereof, on such earlier date as such Lender may specify to the Borrower with a
copy to the Administrative Agent) and, unless and until such Lender gives notice
as provided below that the circumstances specified in Section 3.7, 3.8 or 3.9
hereof that gave rise to such Conversion no longer exist:

                  (a)      to the extent that such Lender's Eurodollar Loans
         have been so Converted, all payments and prepayments of principal that
         would otherwise be applied to such Lender's Eurodollar Loans shall be
         applied instead to its Base Rate Loans; and

                  (b)      all Loans that would otherwise be made or Continued
         by such Lender as Eurodollar Loans shall be made or Continued instead
         as Base Rate Loans, and all Base Rate Loans of such Lender that would
         otherwise be Converted into Eurodollar Loans shall remain as Base Rate
         Loans.

If such Lender gives notice to the Borrower (with a copy to the Administrative
Agent) that the circumstances specified in Section 3.7, 3.8 or 3.9 hereof that
gave rise to the Conversion of such Lender's Eurodollar Loans pursuant to this
Section 3.10 no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Loans made by other
Lenders are outstanding, such Lender's Base Rate Loans shall be automatically
Converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Eurodollar Loans (but in any event not earlier than three
Business Days after the date on which such circumstances cease to exist), to the
extent necessary so that, after giving effect thereto, all Loans held by the
Lenders holding Eurodollar Loans and by such Lender are held pro rata (as to
principal amounts, interest rate basis, and Interest Periods) in accordance with
their respective Commitments.

         3.11     TAXES.

                  (a)      Any and all payments by any Credit Party to or for
         the account of any Lender or the Administrative Agent hereunder or
         under any other Credit Document shall be made free and clear of and
         without deduction for any and all present or future taxes, duties,
         levies, imposts, deductions, charges or withholdings, and all
         liabilities with respect thereto, excluding, in the case of each Lender
         and the Administrative Agent, taxes imposed on its income, and
         franchise taxes imposed on it, by the jurisdiction under the laws of
         which such Lender (or its Applicable Lending Office) or the
         Administrative Agent (as the case may be) is organized or any political
         subdivision thereof (all such non-excluded taxes, duties, levies,
         imposts, deductions, charges, withholdings, and liabilities being
         hereinafter referred to as "Taxes"). If any Credit Party shall be
         required by law to deduct any Taxes from or in respect of any sum
         payable under this Credit Agreement or any other Credit Document to any
         Lender or the Administrative Agent, (i) the sum payable shall be
         increased as necessary so that after making all required deductions
         (including deductions applicable to additional sums payable under this
         Section 3.11) such Lender or the Administrative Agent receives an
         amount equal to the sum it would have received had no such deductions
         been made, (ii) such Credit Party shall make such deductions, (iii)
         such Credit Party shall pay the full amount deducted to the relevant
         taxation authority or other authority in accordance with applicable
         law, and (iv) such Credit Party shall furnish to the Administrative
         Agent, at its address referred to in Section 11.1, the original or a
         certified copy of a receipt evidencing payment thereof.

                  (b)      In addition, the Borrower agrees to pay any and all
         present or future stamp or documentary taxes and any other excise or
         property taxes or charges or similar levies which arise from any
         payment made under this Credit Agreement or any other Credit Document
         or from the execution or delivery of, or otherwise with respect to,
         this Credit Agreement or any other Credit Document (hereinafter
         referred to as "Other Taxes").

                  (c)      The Borrower agrees to indemnify each Lender and the
         Administrative Agent for the full amount of Taxes and Other Taxes
         (including, without limitation, any Taxes or Other Taxes imposed or
         asserted by any jurisdiction on amounts payable under this Section
         3.11) paid by such Lender or the Administrative Agent (as the case may
         be) and any liability (including penalties, interest, and expenses)
         arising therefrom or with respect thereto.

                  (d)      Each Lender that is not a United States person under
         Section 7701(a)(30) of the Code, on or prior to the date of its
         execution and delivery of this Credit Agreement in the case of each
         Lender listed on the signature pages hereof and on or prior to the date
         on which it becomes a Lender in the case of each other Lender, and from
         time to time thereafter if requested in writing by the Borrower or the
         Administrative Agent (but only so long as such Lender remains lawfully
         able to do so), shall provide the Borrower and the Administrative Agent
         with (i) Internal Revenue Service Form 1001 or 4224, as appropriate, or
         any successor form prescribed by the Internal Revenue Service,
         certifying that such Lender is entitled to benefits under an income tax
         treaty to which the United States is a party which reduces the rate of
         withholding tax on payments of interest or certifying that the income
         receivable pursuant to this Credit Agreement is effectively connected
         with the conduct of a trade or business in the United States, (ii)
         Internal Revenue Service Form W-8


                                       48
<PAGE>   54
         or W-9, as appropriate, or any successor form prescribed by the
         Internal Revenue Service, and/or (iii) any other form or certificate
         required by any taxing authority (including any certificate required by
         Sections 871(h) and 881(c) of the Internal Revenue Code), certifying
         that such Lender is entitled to an exemption from or a reduced rate of
         tax on payments pursuant to this Credit Agreement or any of the other
         Credit Documents.

                  (e)      For any period with respect to which a Lender has
         failed to provide the Borrower and the Administrative Agent with the
         appropriate form pursuant to Section 3.11(d) (unless such failure is
         due to a change in treaty, law, or regulation occurring subsequent to
         the date on which a form originally was required to be provided), such
         Lender shall not be entitled to indemnification under Section 3.11(a)
         or 3.11(b) with respect to Taxes imposed by the United States;
         provided, however, that should a Lender, which is otherwise exempt from
         or subject to a reduced rate of withholding tax, become subject to
         Taxes because of its failure to deliver a form required hereunder, the
         Borrower shall take such steps as such Lender shall reasonably request
         to assist such Lender to recover such Taxes.

                  (f)      If any Credit Party is required to pay additional
         amounts to or for the account of any Lender pursuant to this Section
         3.11, then such Lender will agree to use reasonable efforts to change
         the jurisdiction of its Applicable Lending Office so as to eliminate or
         reduce any such additional payment which may thereafter accrue if such
         change, in the judgment of such Lender, is not otherwise
         disadvantageous to such Lender.

                  (g)      Within thirty (30) days after the date of any payment
         of Taxes, the applicable Credit Party shall furnish to the
         Administrative Agent the original or a certified copy of a receipt
         evidencing such payment.

                  (h)      Without prejudice to the survival of any other
         agreement of the Credit Parties hereunder, the agreements and
         obligations of the Credit Parties contained in this Section 3.11 shall
         survive the repayment of the Loans, LOC Obligations and other
         obligations under the Credit Documents and the termination of the
         Commitments hereunder.

         3.12     COMPENSATION.

         Upon the request of any Lender, the Borrower shall pay to such Lender
such amount or amounts as shall be sufficient (in the reasonable opinion of such
Lender) to compensate it for any loss, cost, or expense (including loss of
anticipated profits) incurred by it as a result of:

                  (a)      any payment, prepayment, or Conversion of a
         Eurodollar Loan for any reason (including, without limitation, (i) in
         connection with any assignment by NationsBank pursuant to Section
         11.3(b) as part of the primary syndication of the Loans during the
         180-day period immediately following the Closing Date and (ii) the
         acceleration of the Loans pursuant to Section 9.2) on a date other than
         the last day of the Interest Period for such Loan; or

                  (b)      any failure by the Borrower for any reason
         (including, without limitation, the failure of any condition precedent
         specified in Section 5 to be satisfied) to borrow,


                                       49
<PAGE>   55
         Convert,Continue, or prepay a Eurodollar Loan on the date for such
         borrowing, Conversion, Continuation, or prepayment specified in the
         relevant notice of borrowing, prepayment, Continuation, or Conversion
         under this Credit Agreement.

With respect to Eurodollar Loans, such indemnification may include an amount
equal to the excess, if any, of (a) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, converted or continued,
for the period from the date of such prepayment or of such failure to borrow,
convert or continue to the last day of the applicable Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period that
would have commenced on the date of such failure) in each case at the applicable
rate of interest for such Eurodollar Loans provided for herein (excluding,
however, the Applicable Percentage included therein, if any) over (b) the amount
of interest (as reasonably determined by such Lender) which would have accrued
to such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank Eurodollar market. The covenants of
the Borrower set forth in this Section 3.12 shall survive the repayment of the
Loans, LOC Obligations and other obligations under the Credit Documents and the
termination of the Commitments hereunder.

         3.13     PRO RATA TREATMENT.

         Except to the extent otherwise provided herein:

                  (a)      Loans. Each Loan, each payment or (subject to the
         terms of Section 3.3) prepayment of principal of any Loan or
         reimbursement obligations arising from drawings under Letters of
         Credit, each payment of interest on the Loans or reimbursement
         obligations arising from drawings under Letters of Credit, each payment
         of Unused Fees, each payment of the Letter of Credit Fee, each
         reduction of the Revolving Committed Amount and each conversion or
         extension of any Loan, shall be allocated pro rata among the Lenders in
         accordance with the respective principal amounts of their outstanding
         Loans and Participation Interests.

                  (b)      Advances. No Lender shall be responsible for the
         failure or delay by any other Lender in its obligation to make its
         ratable share of a borrowing hereunder; provided, however, that the
         failure of any Lender to fulfill its obligations hereunder shall not
         relieve any other Lender of its obligations hereunder. Unless the
         Administrative Agent shall have been notified by any Lender prior to
         the date of any requested borrowing that such Lender does not intend to
         make available to the Administrative Agent its ratable share of such
         borrowing to be made on such date, the Administrative Agent may assume
         that such Lender has made such amount available to the Administrative
         Agent on the date of such borrowing, and the Administrative Agent in
         reliance upon such assumption, may (in its sole discretion but without
         any obligation to do so) make available to the Borrower a corresponding
         amount. If such corresponding amount is not in fact made available to
         the Administrative Agent, the Administrative Agent shall be able to
         recover such corresponding amount from such Lender. If such Lender does
         not pay such corresponding amount forthwith upon the Administrative
         Agent's demand therefor, the Administrative Agent shall attempt, in
         good faith, to obtain the commitment of a third party to be an assignee
         of such Lender, and if such commitment is not obtained within three
         Business Days of the commencement of the Administrative Agent's
         efforts, the Administrative Agent will promptly notify the Borrower,
         and the Borrower shall immediately pay such corresponding amount to the


                                       50
<PAGE>   56
         Administrative Agent. The Administrative Agent shall also be entitled
         to recover from the Lender or the Borrower, as the case may be,
         interest on such corresponding amount in respect of each day from the
         date such corresponding amount was made available by the Administrative
         Agent to the Borrower to the date such corresponding amount is
         recovered by the Administrative Agent at a per annum rate equal to (i)
         from the Borrower at the applicable rate for the applicable borrowing
         pursuant to the Notice of Borrowing and (ii) from a Lender at the
         Federal Funds Rate.

         3.14     SHARING OF PAYMENTS.

         The Lenders agree among themselves that, in the event that any Lender
shall obtain payment in respect of any Loan, LOC Obligations or any other
obligation owing to such Lender under this Credit Agreement through the exercise
of a right of setoff, banker's lien or counterclaim, or pursuant to a secured
claim under Section 506 of Title 11 of the United States Code or other security
or interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise, or by any other means, in excess of its pro rata share of such
payment as provided for in this Credit Agreement, such Lender shall promptly
purchase from the other Lenders a Participation Interest in such Loans, LOC
Obligations and other obligations in such amounts, and make such other
adjustments from time to time, as shall be equitable to the end that all Lenders
share such payment in accordance with their respective ratable shares as
provided for in this Credit Agreement. The Lenders further agree among
themselves that if payment to a Lender obtained by such Lender through the
exercise of a right of setoff, banker's lien, counterclaim or other event as
aforesaid shall be rescinded or must otherwise be restored, each Lender which
shall have shared the benefit of such payment shall, by repurchase of a
Participation Interest theretofore sold, return its share of that benefit
(together with its share of any accrued interest payable with respect thereto)
to each Lender whose payment shall have been rescinded or otherwise restored.
The Borrower agrees that any Lender so purchasing such a Participation Interest
may, to the fullest extent permitted by law, exercise all rights of payment,
including setoff, banker's lien or counterclaim, with respect to such
Participation Interest as fully as if such Lender were a holder of such Loan,
LOC Obligations or other obligation in the amount of such Participation
Interest. Except as otherwise expressly provided in this Credit Agreement, if
any Lender or the Administrative Agent shall fail to remit to the Administrative
Agent or any other Lender an amount payable by such Lender or the Administrative
Agent to the Administrative Agent or such other Lender pursuant to this Credit
Agreement on the date when such amount is due, such payments shall be made
together with interest thereon for each date from the date such amount is due
until the date such amount is paid to the Administrative Agent or such other
Lender at a rate per annum equal to the Federal Funds Rate. If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this Section 3.14 applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders under this
Section 3.14 to share in the benefits of any recovery on such secured claim.

         3.15     PAYMENTS, COMPUTATIONS, ETC.

                  (a)      Except as otherwise specifically provided herein, all
         payments hereunder shall be made to the Administrative Agent in dollars
         in immediately available funds, without setoff, deduction, counterclaim
         or withholding of any kind, at the Administrative Agent's office
         specified in Schedule 2.1(a) not later than 2:00 P.M. (Charlotte, North


                                       51
<PAGE>   57
         Carolina time) on the date when due. Payments received after such time
         shall be deemed to have been received on the next succeeding Business
         Day. The Administrative Agent may (but shall not be obligated to) debit
         the amount of any such payment which is not made by such time to any
         ordinary deposit account of the Borrower or any other Credit Party
         maintained with the Administrative Agent (with notice to the Borrower
         or such other Credit Party). The Borrower shall, at the time it makes
         any payment under this Credit Agreement, specify to the Administrative
         Agent the Loans, LOC Obligations, Fees, interest or other amounts
         payable by the Borrower hereunder to which such payment is to be
         applied (and in the event that it fails so to specify, or if such
         application would be inconsistent with the terms hereof, the
         Administrative Agent shall distribute such payment to the Lenders in
         such manner as the Administrative Agent may determine to be appropriate
         in respect of obligations owing by the Borrower hereunder, subject to
         the terms of Section 3.13(a)). The Administrative Agent will distribute
         such payments to such Lenders, if any such payment is received prior to
         12:00 Noon (Charlotte, North Carolina time) on a Business Day in like
         funds as received prior to the end of such Business Day and otherwise
         the Administrative Agent will distribute such payment to such Lenders
         on the next succeeding Business Day. Whenever any payment hereunder
         shall be stated to be due on a day which is not a Business Day, the due
         date thereof shall be extended to the next succeeding Business Day
         (subject to accrual of interest and Fees for the period of such
         extension), except that in the case of Eurodollar Loans, if the
         extension would cause the payment to be made in the next following
         calendar month, then such payment shall instead be made on the next
         preceding Business Day. Except as expressly provided otherwise herein,
         all computations of interest and fees shall be made on the basis of
         actual number of days elapsed over a year of 360 days, except with
         respect to computation of interest on Base Rate Loans which shall be
         calculated based on a year of 365 or 366 days, as appropriate. Interest
         shall accrue from and include the date of borrowing, but exclude the
         date of payment.

                  (b)      Allocation of Payments After Event of Default.
         Notwithstanding any other provisions of this Credit Agreement to the
         contrary, after the occurrence and during the continuance of an Event
         of Default, all amounts collected or received by the Administrative
         Agent or any Lender on account of the Credit Party Obligations or any
         other amounts outstanding under any of the Credit Documents or in
         respect of the Collateral shall be paid over or delivered as follows:

                  FIRST, to the payment of all reasonable out-of-pocket costs
         and expenses (including, without limitation, reasonable attorneys'
         fees) of the Administrative Agent in connection with enforcing the
         rights of the Lenders under the Credit Documents and any protective
         advances made by the Administrative Agent with respect to the
         Collateral under or pursuant to the terms of the Collateral Documents;

                  SECOND, to payment of any fees owed to the Administrative
         Agent;

                  THIRD, to the payment of all reasonable out-of-pocket costs
         and expenses (including, without limitation, reasonable attorneys'
         fees) of each of the Lenders in connection with enforcing its rights
         under the Credit Documents or otherwise with respect to the Credit
         Party Obligations owing to such Lender;


                                       52
<PAGE>   58
                  FOURTH, to the payment of all of the Credit Party Obligations
         (other than obligations under Hedging Agreements) consisting of accrued
         fees and interest;

                  FIFTH, to the payment of the outstanding principal amount of
         the Credit Party Obligations (including obligations under Hedging
         Agreements between a Credit Party and any Lender or any Affiliate of a
         Lender and the payment or cash collateralization of the outstanding LOC
         Obligations);

                  SIXTH, to all other Credit Party Obligations and other
         obligations which shall have become due and payable under the Credit
         Documents or otherwise and not repaid pursuant to clauses "FIRST"
         through "FIFTH" above; and

                  SEVENTH, to the payment of the surplus, if any, to whoever may
         be lawfully entitled to receive such surplus.

         In carrying out the foregoing, (i) amounts received shall be applied in
         the numerical order provided until exhausted prior to application to
         the next succeeding category; (ii) each of the Lenders shall receive an
         amount equal to its pro rata share (based on the proportion that the
         then outstanding Loans and LOC Obligations held by such Lender bears to
         the aggregate then outstanding Loans and LOC Obligations) of amounts
         available to be applied pursuant to clauses "THIRD", "FOURTH", "FIFTH"
         and "SIXTH" above; and (iii) to the extent that any amounts available
         for distribution pursuant to clause "FIFTH" above are attributable to
         the issued but undrawn amount of outstanding Letters of Credit, such
         amounts shall be held by the Administrative Agent in a cash collateral
         account and applied (A) first, to reimburse the Issuing Lender from
         time to time for any drawings under such Letters of Credit and (B)
         then, following the expiration of all Letters of Credit, to all other
         obligations of the types described in clauses "FIFTH" and "SIXTH" above
         in the manner provided in this Section 3.15(b).

         3.16     EVIDENCE OF DEBT.

                  (a)      Each Lender shall maintain an account or accounts
         evidencing each Loan made by such Lender to the Borrower from time to
         time, including the amounts of principal and interest payable and paid
         to such Lender from time to time under this Credit Agreement. Each
         Lender will make reasonable efforts to maintain the accuracy of its
         account or accounts and to promptly update its account or accounts from
         time to time, as necessary.

                  (b)      The Administrative Agent shall maintain the Register
         pursuant to Section 11.3(c), and a subaccount for each Lender, in which
         Register and subaccounts (taken together) shall be recorded (i) the
         amount, type and Interest Period of each such Loan hereunder, (ii) the
         amount of any principal or interest due and payable or to become due
         and payable to each Lender hereunder and (iii) the amount of any sum
         received by the Administrative Agent hereunder from or for the account
         of any Credit Party and each Lender's share thereof. The Administrative
         Agent will make reasonable efforts to maintain the accuracy of the
         subaccounts referred to in the preceding sentence and to promptly
         update such subaccounts from time to time, as necessary.


                                       53
<PAGE>   59
                  (c)      The entries made in the accounts, Register and
         subaccounts maintained pursuant to subsection (b) of this Section 3.16
         (and, if consistent with the entries of the Administrative Agent,
         subsection (a)) shall be prima facie evidence of the existence and
         amounts of the obligations of the Credit Parties therein recorded;
         provided, however, that the failure of any Lender or the Administrative
         Agent to maintain any such account, such Register or such subaccount,
         as applicable, or any error therein, shall not in any manner affect the
         obligation of the Credit Parties to repay the Credit Party Obligations
         owing to such Lender.


                                    SECTION 4

                                    GUARANTY

         4.1      THE GUARANTY.

         In consideration for the making of the Loans and the potential
providing of a portion of the proceeds thereof directly to the Guarantors, each
of the Guarantors hereby jointly and severally guarantees to each Lender, each
Affiliate of a Lender that enters into a Hedging Agreement with any Credit
Party, and the Administrative Agent as hereinafter provided, as primary obligor
and not as surety, the prompt payment of the Credit Party Obligations in full
when due (whether at stated maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise) strictly in
accordance with the terms thereof. The Guarantors hereby further agree that if
any of the Credit Party Obligations are not paid in full when due (whether at
stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash
collateralization or otherwise), the Guarantors will, jointly and severally,
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Credit Party
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, as a mandatory prepayment, by acceleration, as a mandatory
cash collateralization or otherwise) in accordance with the terms of such
extension or renewal.

         Notwithstanding any provision to the contrary contained herein or in
any other of the Credit Documents or Hedging Agreements between any Credit Party
and any Lender (or any Affiliate of a Lender), the obligations of each Guarantor
under this Credit Agreement and the other Credit Documents shall be limited to
an aggregate amount equal to the largest amount that would not render such
obligations subject to avoidance under Section 548 of the Bankruptcy Code or any
comparable provisions of any applicable state law.

         4.2      OBLIGATIONS UNCONDITIONAL.

         The obligations of the Guarantors under Section 4.1 are joint and
several, absolute and unconditional, irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Credit Documents or Hedging
Agreements between any Credit Party and any Lender (or any Affiliate of a
Lender), or any other agreement or instrument referred to therein, or any
substitution, release, impairment or exchange of any other guarantee of or
security for any of the Credit Party Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever
which might otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor, it being the intent of this Section 4.2 that the
obligations of the Guarantors


                                       54
<PAGE>   60
hereunder shall be absolute and unconditional under any and all circumstances.
Each Guarantor agrees that such Guarantor shall have no right of subrogation,
indemnity, reimbursement or contribution against the Borrower or any other
Guarantor for amounts paid under this Section 4 until such time as the Lenders
(and any Affiliates of Lenders entering into Hedging Agreements with any Credit
Party) have been paid in full in respect of all Credit Party Obligations, all
Commitments under this Credit Agreement have been terminated and no Person or
Governmental Authority shall have any right to request any return or
reimbursement of funds from the Lenders in connection with monies received under
the Credit Documents or Hedging Agreements between any Credit Party and any
Lender, or any Affiliate of a Lender. Without limiting the generality of the
foregoing, it is agreed that, to the fullest extent permitted by law, the
occurrence of any one or more of the following shall not alter or impair the
liability of any Guarantor hereunder which shall remain absolute and
unconditional as described above:

                  (a)      at any time or from time to time, without notice to
         any Guarantor, the time for any performance of or compliance with any
         of the Credit Party Obligations shall be extended, or such performance
         or compliance shall be waived;

                  (b)      any of the acts mentioned in any of the provisions of
         any of the Credit Documents, any Hedging Agreement between any
         Consolidated Party and any Lender, or any Affiliate of a Lender, or any
         other agreement or instrument referred to in the Credit Documents or
         such Hedging Agreements shall be done or omitted;

                  (c)      the maturity of any of the Credit Party Obligations
         shall be accelerated, or any of the Credit Party Obligations shall be
         modified, supplemented or amended in any respect, or any right under
         any of the Credit Documents, any Hedging Agreement between any
         Consolidated Party and any Lender, or any Affiliate of a Lender, or any
         other agreement or instrument referred to in the Credit Documents or
         such Hedging Agreements shall be waived or any other guarantee of any
         of the Credit Party Obligations or any security therefor shall be
         released, impaired or exchanged in whole or in part or otherwise dealt
         with;

                  (d)      any Lien granted to, or in favor of, the
         Administrative Agent or any Lender or Lenders as security for any of
         the Credit Party Obligations shall fail to attach or be perfected; or

                  (e)      any of the Credit Party Obligations shall be
         determined to be void or voidable (including, without limitation, for
         the benefit of any creditor of any Guarantor) or shall be subordinated
         to the claims of any Person (including, without limitation, any
         creditor of any Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Administrative Agent or any Lender
exhaust any right, power or remedy or proceed against any Person under any of
the Credit Documents, any Hedging Agreement between any Consolidated Party and
any Lender, or any Affiliate of a Lender, or any other agreement or instrument
referred to in the Credit Documents or such Hedging Agreements, or against any
other Person under any other guarantee of, or security for, any of the Credit
Party Obligations.

<PAGE>   61
         4.3      REINSTATEMENT.

         The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Credit Party Obligations is
rescinded or must be otherwise restored by any holder of any of the Credit Party
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
the Administrative Agent and each Lender on demand for all reasonable costs and
expenses (including, without limitation, fees and expenses of counsel) incurred
by the Administrative Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

         4.4      CERTAIN ADDITIONAL WAIVERS.

         Without limiting the generality of the provisions of this Section 4,
each Guarantor hereby specifically waives the benefits of N.C. Gen. Stat.
Sections 26-7 through 26-9, inclusive, to the extent applicable. Each Guarantor
further agrees that such Guarantor shall have no right of recourse to security
for the Credit Party Obligations, except through the exercise of rights of
subrogation pursuant to Section 4.2 and through the exercise of rights of
contribution pursuant to Section 4.6.

         4.5      REMEDIES.

         The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Administrative Agent and the
Lenders, on the other hand, the Credit Party Obligations may be declared to be
forthwith due and payable as provided in Section 9.2 (and shall be deemed to
have become automatically due and payable in the circumstances provided in said
Section 9.2) for purposes of Section 4.1 notwithstanding any stay, injunction or
other prohibition preventing such declaration (or preventing the Credit Party
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or the Credit Party
Obligations being deemed to have become automatically due and payable), the
Credit Party Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors for purposes of Section
4.1. The Guarantors acknowledge and agree that their obligations hereunder are
secured in accordance with the terms of the Security Agreements and the other
Collateral Documents and that the Lenders may exercise their remedies thereunder
in accordance with the terms thereof.

         4.6      RIGHTS OF CONTRIBUTION.

         The Guarantors hereby agree as among themselves that, if any Guarantor
shall make an Excess Payment (as defined below), such Guarantor shall have a
right of contribution from each other Guarantor in an amount equal to such other
Guarantor's Contribution Share (as defined below) of such Excess Payment. The
payment obligations of any Guarantor under this Section 4.6 shall be subordinate
and subject in right of payment to the prior payment in full to the
Administrative Agent and the Lenders of the Guaranteed Obligations, and none of
the Guarantors shall exercise any right or remedy under this Section 4.6 against
any other Guarantor until payment and satisfaction in full of all of such
Guaranteed Obligations. For purposes of this Section 4.6, (a) "Guaranteed
Obligations" shall mean any obligations arising under the other provisions of
this 


                                       56
<PAGE>   62
Section 4; (b) "Excess Payment" shall mean the amount paid by any Guarantor in
excess of its Pro Rata Share of any Guaranteed Obligations; (c) "Pro Rata Share"
shall mean, for any Guarantor in respect of any payment of Guaranteed
Obligations, the ratio (expressed as a percentage) as of the date of such
payment of Guaranteed Obligations of (i) the amount by which the aggregate
present fair salable value of all of its assets and properties exceeds the
amount of all debts and liabilities of such Guarantor (including contingent,
subordinated, unmatured, and unliquidated liabilities, but excluding the
obligations of such Guarantor hereunder) to (ii) the amount by which the
aggregate present fair salable value of all assets and other properties of all
of the Credit Parties exceeds the amount of all of the debts and liabilities
(including contingent, subordinated, unmatured, and unliquidated liabilities,
but excluding the obligations of the Credit Parties hereunder) of the Credit
Parties; provided, however, that, for purposes of calculating the Pro Rata
Shares of the Guarantors in respect of any payment of Guaranteed Obligations,
any Guarantor that became a Guarantor subsequent to the date of any such payment
shall be deemed to have been a Guarantor on the date of such payment and the
financial information for such Guarantor as of the date such Guarantor became a
Guarantor shall be utilized for such Guarantor in connection with such payment;
and (d) "Contribution Share" shall mean, for any Guarantor in respect of any
Excess Payment made by any other Guarantor, the ratio (expressed as a
percentage) as of the date of such Excess Payment of (i) the amount by which the
aggregate present fair salable value of all of its assets and properties exceeds
the amount of all debts and liabilities of such Guarantor (including contingent,
subordinated, unmatured, and unliquidated liabilities, but excluding the
obligations of such Guarantor hereunder) to (ii) the amount by which the
aggregate present fair salable value of all assets and other properties of the
Credit Parties other than the maker of such Excess Payment exceeds the amount of
all of the debts and liabilities (including contingent, subordinated, unmatured,
and unliquidated liabilities, but excluding the obligations of the Credit
Parties) of the Credit Parties other than the maker of such Excess Payment;
provided, however, that, for purposes of calculating the Contribution Shares of
the Guarantors in respect of any Excess Payment, any Guarantor that became a
Guarantor subsequent to the date of any such Excess Payment shall be deemed to
have been a Guarantor on the date of such Excess Payment and the financial
information for such Guarantor as of the date such Guarantor became a Guarantor
shall be utilized for such Guarantor in connection with such Excess Payment.
This Section 4.6 shall not be deemed to affect any right of subrogation,
indemnity, reimbursement or contribution that any Guarantor may have under
applicable law against the Borrower in respect of any payment of Guaranteed
Obligations. Notwithstanding the foregoing, all rights of contribution against
any Guarantor shall terminate from and after such time, if ever, that such
Guarantor shall be relieved of its obligations pursuant to Section 8.4.

         4.7      GUARANTEE OF PAYMENT; CONTINUING GUARANTEE.

         The guarantee in this Section 4 is a guaranty of payment and not of
collection, is a continuing guarantee, and shall apply to all Credit Party
Obligations whenever arising.

                                   CONDITIONS

         not vested, under each Single Employer Plan, as of the last annual
         valuation date prior to the date on which this representation is made
         or deemed made (determined, in each case, in accordance with Financial
         Accounting Standards Board Statement 87, utilizing the actuarial
         assumptions used in such Plan's most recent actuarial valuation
         report), did not exceed as of such valuation date the fair market value
         of the assets of such Plan.

                  (c)      Neither any Consolidated Party nor any ERISA
         Affiliate has incurred, or, to the best knowledge of the Credit
         Parties, could be reasonably expected to incur, any withdrawal
         liability under ERISA to any Multiemployer Plan or Multiple Employer
         Plan. Neither any Consolidated Party nor any ERISA Affiliate would
         become subject to any withdrawal liability under ERISA if any
         Consolidated Party or any ERISA Affiliate were to withdraw completely
         from all Multiemployer Plans and Multiple Employer Plans as of the
         valuation date most closely preceding the date on which this
         representation is made or deemed made. Neither any Consolidated Party
         nor any ERISA Affiliate has received any notification that any
         Multiemployer Plan is in reorganization (within the meaning of Section
         4241 of ERISA), is insolvent (within the meaning of Section 4245 of
         ERISA), or has been terminated (within the meaning of Title IV of
         ERISA), and no Multiemployer Plan is, to the best knowledge of the
         Credit Parties, reasonably expected to be in reorganization, insolvent,
         or terminated.

                  (d)      No prohibited transaction (within the meaning of
         Section 406 of ERISA or Section 4975 of the Code) or breach of
         fiduciary responsibility has occurred with respect to a Plan which has
         subjected or may subject any Consolidated Party or any ERISA Affiliate
         to any liability under Sections 406, 409, 502(i), or 502(l) of ERISA or
         Section 4975 of the Code, or under any agreement or other instrument
         pursuant to which any Consolidated Party or any ERISA Affiliate has
         agreed or is required to indemnify any Person against any such
         liability.

                  (e)      Neither any Consolidated Party nor any ERISA
         Affiliates has any material liability with respect to "expected
         post-retirement benefit obligations" within the meaning of the
         Financial Accounting Standards Board Statement 106. Each Plan which is
         a welfare


                                       70
<PAGE>   76
         plan (as defined in Section 3(1) of ERISA) to which Sections 601-609
         of ERISA and Section 4980B of the Code apply has been administered in
         compliance in all material respects of such sections.

                  (f)      Neither the execution and delivery of this Credit
         Agreement nor the consummation of the financing transactions
         contemplated thereunder will involve any transaction which is subject
         to the prohibitions of Sections 404, 406 or 407 of ERISA or in
         connection with which a tax could be imposed pursuant to Section 4975
         of the Code. The representation by the Credit Parties in the preceding
         sentence is made in reliance upon and subject to the accuracy of the
         Lenders' representation in Section 11.15 with respect to their source
         of funds and is subject, in the event that the source of the funds used
         by the Lenders in connection with this transaction is an insurance
         company's general asset account, to the application of Prohibited
         Transaction Class Exemption 95-60, 60 Fed. Reg. 35,925 (1995),
         compliance with the regulations issued under Section 401(c)(1)(A) of
         ERISA, or the issuance of any other prohibited transaction exemption or
         similar relief, to the effect that assets in an insurance company's
         general asset account do not constitute assets of an "employee benefit
         plan" within the meaning of Section 3(3) of ERISA of a "plan" within
         the meaning of Section 4975(e)(1) of the Code.

         6.13     SUBSIDIARIES.

Stock outstanding, the number and percentage of outstanding shares of each class
owned (directly or indirectly) by such Consolidated Party; and the number and
effect, if exercised, of all outstanding options, warrants, rights of conversion
or purchase and all other similar rights with respect thereto. The outstanding
Capital Stock of all such Subsidiaries is validly issued, fully paid and
non-assessable and is owned by each such Consolidated Party, directly or
indirectly, free and clear of all Liens (other than those arising under or
contemplated in connection with the Credit Documents). Other than as set forth
in Schedule 6.13, no Consolidated Party has outstanding any securities
convertible into or exchangeable for its Capital Stock nor does any such Person
have outstanding any rights to subscribe for or to purchase or any options for
the purchase of, or any agreements providing for the issuance (contingent or
otherwise) of, or any calls, commitments or claims of any character relating to
its Capital Stock.

         6.14     GOVERNMENTAL REGULATIONS, ETC.

                  (a)      No part of the Letters of Credit or proceeds of the
         Loans will be used, directly or indirectly, for the purpose of
         purchasing or carrying any "margin stock" within the meaning of
         Regulation U, or for the purpose of purchasing or carrying or trading
         in any securities. If requested by any Lender or the Administrative
         Agent, the Borrower will furnish to the Administrative Agent and each
         Lender a statement to the foregoing effect in conformity with the
         requirements of FR Form U-1 referred to in Regulation U. No
         indebtedness being reduced or retired out of the proceeds of the Loans
         was or will be incurred for the purpose of purchasing or carrying any
         margin stock within the meaning of Regulation U or any "margin
         security" within the meaning of Regulation T. "Margin stock" within the
         meaning of Regulation U does not constitute more than 25% of the value
         of the consolidated assets of the Consolidated Parties. None of the
         transactions contemplated by


                                       71
<PAGE>   77
         this Credit Agreement (including, without limitation, the direct or
         indirect use of the proceeds of the Loans) will violate or result in a
         violation of the Securities Act of 1933, as amended, or the Securities
         Exchange Act of 1934, as amended, or regulations issued pursuant
         thereto, or Regulation T, U or X.

         the Public Utility Holding Company Act of 1935, the Federal Power Act
         or the Investment Company Act of 1940, each as amended. In addition, no
         Consolidated Party is (i) an "investment company" registered or
         required to be registered under the Investment Company Act of 1940, as
         amended, and is not controlled by such a company, or (ii) a "holding
         company", or a "subsidiary company" of a "holding company", or an
         "affiliate" of a "holding company" or of a "subsidiary" of a "holding
         company", within the meaning of the Public Utility Holding Company Act
         of 1935, as amended.

                  (c)      No director, executive officer or principal
         shareholder of any Consolidated Party is a director, executive officer
         or principal shareholder of any Lender. For the purposes hereof the
         terms "director", "executive officer" and "principal shareholder" (when
         used with reference to any Lender) have the respective meanings
         assigned thereto in Regulation O issued by the Board of Governors of
         the Federal Reserve System.

                  (d)      Each Consolidated Party has obtained and holds in
         full force and effect, all franchises, licenses, permits, certificates,
         authorizations, qualifications, accreditations, easements, rights of
         way and other rights, consents and approvals which are necessary for
         the ownership of its respective Property and to the conduct of its
         respective businesses as presently conducted.

                  (e)      No Consolidated Party is in violation of any
         applicable statute, regulation or ordinance of the United States, or of
         any state, city, town, municipality, county or any other jurisdiction,
         or of any agency thereof (including, without limitation, environmental
         laws and regulations), which violation could have a Material Adverse
         Effect.

                  (f)      Each Consolidated Party is current with all material
         reports and documents, if any, required to be filed with any state or
         federal securities commission or similar agency and is in full
         compliance in all material respects with all applicable rules and
         regulations of such commissions.

         The proceeds of the Loans hereunder shall be used solely by the
Borrower to (a) finance a portion of a $48,000,000 cash distribution to the

         Environmental Laws.

                  (c)      No Consolidated Party has received any written or

         or liability could reasonably have a Material Adverse Effect.

                  (e)      No judicial proceeding or governmental or
         administrative action is pending or, to the best knowledge of any
         Credit Party, threatened, under any Environmental Law to which any
         Consolidated Party is or will be named as a party, nor are there any

         or other orders, or other administrative or judicial requirements
         outstanding under any Environmental Law with respect to the
         Consolidated Parties, the Real Properties or the Businesses, in each
         case which could reasonably have a Material Adverse Effect.

                  (f)      There has been no release, or threat of release, of
         Materials of Environmental Concern at or from the Real Properties, or
         arising from or related to the operations (including, without

         Real Properties or otherwise in connection with the Businesses, in
         violation of or in amounts or in a manner that could give rise to
         liability under Environmental Laws, which violation or liability could
         reasonably have a Material Adverse Effect.

         Parties will give written notice to the Administrative Agent
         immediately of (i) the occurrence of an event or condition consisting

         federal, state or local law, rule or regulation, including but not
         limited to, Environmental Laws, the violation of which could have a
         Material Adverse Effect.

                  (k)      ERISA. Upon obtaining knowledge thereof, the Credit
         Parties will give written notice to the Administrative Agent promptly
         (and in any event within five Business Days) of: (i) any event or
         condition, including, but not limited to, any Reportable Event, that
         constitutes, or might reasonably lead to, an ERISA Event; (ii) with
         respect to any Multiemployer Plan, the receipt of notice as prescribed
         in ERISA or otherwise of any withdrawal liability assessed against the
         Credit Parties or any ERISA Affiliates, or of a determination that any
         Multiemployer Plan is in reorganization or insolvent (both within the
         meaning of Title IV of ERISA); (iii) the failure to make full payment
         on or before the due date (including extensions) thereof of all amounts

         the minimum funding standard set forth in ERISA and the Code with
         respect thereto; or (iv) any change in the funding status of any Plan
         that could have a Material Adverse Effect, together with a description
         of any such event or condition or a copy of any such notice and a

         and the action, if any, which has been or is being taken or is proposed
         to be taken by the Credit Parties with respect thereto. Promptly upon
         request, the Credit Parties shall furnish the Administrative Agent and
         the Lenders with such additional information concerning any Plan as may
         be reasonably requested, including, but not limited to, copies of each
         annual report/return (Form 5500 series), as well as all schedules and
         attachments thereto required to be filed with the Department of Labor
         and/or the Internal Revenue Service pursuant to ERISA and the Code,
         respectively, for each "plan year" (within the meaning of Section 3(39)

                  (l)      Environmental.

                           (i)      Upon the reasonable written request of the
                  Administrative Agent, the Credit Parties will furnish or cause
                  to be furnished to the Administrative Agent, at the Credit
                  Parties' expense, a report of an environmental assessment of
                  reasonable scope, form and depth, (including, where
                  appropriate, invasive soil or groundwater sampling) by a
                  consultant reasonably acceptable to the Administrative Agent
                  as to the nature and extent of the presence of any Materials
                  of Environmental Concern on any Real Properties (as defined in
                  Section 6.16) and as to the compliance by any Consolidated
                  Party with Environmental Laws at such Real Properties;
                  provided, however, the Credit Parties shall not be required to
                  furnish to the Administrative Agent an environmental
                  assessment with respect to the Glendale Property unless such
                  environmental assessment is required pursuant to Section
                  7.16(b). If the Credit


                                       78
<PAGE>   84
                  Parties fail to deliver such an environmental report within
                  seventy-five (75) days after receipt of such written request
                  then the Administrative Agent may arrange for same, and the
                  Consolidated Parties hereby grant to the Administrative Agent
                  and their representatives access to the Real Properties to
                  reasonably undertake such an assessment (including, where
                  appropriate, invasive soil or groundwater sampling). The
                  reasonable cost of any assessment arranged for by the
                  Administrative Agent pursuant to this provision will be
                  payable by the Credit Parties on demand and added to the
                  obligations secured by the Collateral Documents.

                           (ii)     The Consolidated Parties will conduct and
                  complete all investigations, studies, sampling, and testing
                  and all remedial, removal, and other actions necessary to
                  address all Materials of Environmental Concern on, from or
                  affecting any of the Real Properties to the extent necessary
                  to be in compliance with all Environmental Laws and with the
                  validly issued orders and directives of all Governmental
                  Authorities with jurisdiction over such Real Properties to the
                  extent any failure could have a Material Adverse Effect.

                  (m)      Additional Patents and Trademarks. At the time of
         delivery of the financial statements and reports provided for in
         Section 7.1(a), a report signed by the chief financial officer or
         treasurer of the Borrower setting forth (i) a list of registration
         numbers for all patents, trademarks, service marks, tradenames and
         copyrights awarded to any Consolidated Party since the last day of the
         immediately preceding fiscal year and (ii) a list of all patent
         applications, trademark applications, service mark applications, trade
         name applications and copyright applications submitted by any
         Consolidated Party since the last day of the immediately preceding
         fiscal year and the status of each such application, all in such form
         as shall be reasonably satisfactory to the Administrative Agent.

                  (n)      Other Information. With reasonable promptness upon
         any such request, such other information regarding the business,
         properties or financial condition of any Consolidated Party as the
         Administrative Agent or the Required Lenders may reasonably request.

         7.2      PRESERVATION OF EXISTENCE AND FRANCHISES.

         Except as a result of or in connection with a dissolution, merger or
disposition of a Subsidiary permitted under Section 8.4 or Section 8.5, each
Credit Party will, and will cause each of its Subsidiaries to, do all things
necessary to preserve and keep in full force and effect its existence, rights,
franchises and authority.

         7.3      BOOKS AND RECORDS.

         Each Credit Party will, and will cause each of its Subsidiaries to,
keep complete and accurate books and records of its transactions in accordance
with good accounting practices on the basis of GAAP (including the establishment
and maintenance of appropriate reserves).

         7.4      COMPLIANCE WITH LAW.


                                       79
<PAGE>   85
         Each Credit Party will, and will cause each of its Subsidiaries to,
comply with all laws, rules, regulations and orders, and all applicable
restrictions imposed by all Governmental Authorities, applicable to it and its
Property if noncompliance with any such law, rule, regulation, order or
restriction could have a Material Adverse Effect.

         7.5      PAYMENT OF TAXES AND OTHER INDEBTEDNESS.

         Each Credit Party will, and will cause each of its Subsidiaries to, pay
and discharge (a) all taxes, assessments and governmental charges or levies
imposed upon it, or upon its income or profits, or upon any of its properties,
before they shall become delinquent, (b) all lawful claims (including claims for
labor, materials and supplies) which, if unpaid, might give rise to a Lien upon
any of its properties, and (c) except as prohibited hereunder, all of its other
Indebtedness as it shall become due; provided, however, that no Consolidated
Party shall be required to pay any such tax, assessment, charge, levy, claim or
Indebtedness which is being contested in good faith by appropriate proceedings
and as to which adequate reserves therefor have been established in accordance
with GAAP, unless the failure to make any such payment (i) could give rise to an
immediate right to foreclose on a Lien securing such amounts or (ii) could have
a Material Adverse Effect.

         7.6      INSURANCE.

                  (a)      Each Credit Party will, and will cause each of its
         Subsidiaries to, at all times maintain in full force and effect
         insurance (including worker's compensation insurance, liability
         insurance, casualty insurance and business interruption insurance) in
         such amounts, covering such risks and liabilities and with such
         deductibles or self-insurance retentions as are in accordance with
         normal industry practice (or as otherwise required by the Collateral
         Documents). The Administrative Agent shall be named as loss payee or
         mortgagee, as its interest may appear, and/or additional insured with
         respect to any such insurance providing coverage in respect of any
         Collateral, and each provider of any such insurance shall agree, by
         endorsement upon the policy or policies issued by it or by independent
         instruments furnished to the Administrative Agent, that it will give
         the Administrative Agent thirty (30) days' prior written notice before
         any such policy or policies shall be altered or canceled, and that no
         act or default of any Consolidated Party or any other Person shall
         affect the rights of the Administrative Agent or the Lenders under such
         policy or policies. The present insurance coverage of the Consolidated
         Parties is outlined as to carrier, policy number, expiration date, type
         and amount on Schedule 7.6.

                  (b)      In case of any material loss of, damage to or
         destruction of any Collateral, such Credit Party (i) shall promptly
         give written notice thereof to the Administrative Agent generally
         describing the nature and extent of such damage or destruction, (ii) in
         the event that such Credit Party receives insurance proceeds on account
         of any loss of, damage to or destruction of Collateral in a net amount
         in excess of $500,000 (in respect of any insurance event, the "Excess
         Proceeds"), such Credit Party will immediately pay over such Excess
         Proceeds to the Administrative Agent as cash collateral for the Credit
         Party Obligations and (iii) whether or not the insurance proceeds, if
         any, received on account of such damage or destruction shall be
         sufficient for that purpose, at such Credit Party's cost and expense,
         will promptly repair or replace the Collateral of such Credit Party so
         lost, damaged or destroyed; provided, however, that (A) such Credit
         Party need not repair or replace the Collateral of


                                       80
<PAGE>   86
         such Credit Party so lost, damaged or destroyed to the extent the
         failure to make such repair or replacement (1) is desirable to the
         proper conduct of the business of such Credit Party in the ordinary
         course and otherwise in the best interest of such Credit Party and (2)
         would not materially impair the rights and benefits of the
         Administrative Agent or the Lenders under the Collateral Documents, any
         other Credit Document or any Hedging Agreement between any Consolidated
         Party and any Lender, or any Affiliate of a Lender, and (B) in the
         event that such Credit Party receives insurance proceeds on account of
         any loss of, damage to or destruction of Collateral in a net amount in
         excess of $500,000, such Credit Party shall not undertake replacement
         or restoration of any lost, damaged or destroyed Collateral of such
         Credit Party with insurance proceeds in respect thereof unless (1) the
         Administrative Agent has received evidence reasonably satisfactory to
         it that the Collateral lost, damaged or destroyed has been or will be
         replaced or restored to its condition immediately prior to the loss,
         destruction or other event giving rise to the payment of such insurance
         proceeds and (2) no violation of Section 7.11 would have occurred as of
         the most recent fiscal quarter end preceding the date of determination
         with respect to which the Administrative Agent has received the
         Required Financial Information upon giving pro forma effect to any
         Indebtedness to be incurred in connection with such replacement or
         restoration (assuming, for purposes hereof, that such Indebtedness was
         incurred as of the first day of the four fiscal-quarter period ending
         as of such fiscal quarter end).

                  (c)      With respect to any Excess Proceeds deposited with
         the Administrative Agent by any Credit Party as provided in the
         subsection (b) above, the Administrative Agent agrees to release such
         Excess Proceeds to such Credit Party for replacement or restoration of
         the portion of the Collateral of such Credit Party lost, damaged or
         destroyed, provided that, within 30 days from the date that the
         Administrative Agent receives such Excess Proceeds, the Administrative
         Agent shall have received a written application for release of such
         Excess Proceeds from such Credit Party establishing satisfaction of the
         conditions set forth in clause (B) of subsection (b) above.

                  (d)      Any insurance proceeds received by any Credit Party
         on account of any loss of, damage to or destruction of Collateral that
         (i) are not applied pursuant to clause (A) of subsection (b) above to
         repair or replace the Collateral within the period of 180 days
         following the date the applicable Credit Party receives such proceeds,
         (ii) are not permitted to be applied pursuant to clause (B) of the
         preceding paragraph to repair or replace the Collateral or (iii)
         constitute Excess Proceeds which have been deposited with the
         Administrative Agent and with respect to which the conditions for
         application to replacement or restoration set forth in subsection (c)
         above shall not have been met on or before the first Business Day
         following the date 30 days from the date the Administrative Agent
         receives such Excess Proceeds, shall be applied (by the Credit Parties
         or, in the case of Excess Proceeds held by the Administrative Agent, by
         the Administrative Agent) to prepay the Loans (and cash collateralize
         of LOC Obligations) in accordance with the terms of Section
         3.3(b)(iii)(B).

                  (e)      All insurance proceeds shall be subject to the
         security interest of the Administrative Agent (for the ratable of the
         Lenders) under the Collateral Documents.


                                       81

         7.7      MAINTENANCE OF PROPERTY.

         Each Credit Party will, and will cause each of its Subsidiaries to,
maintain and preserve its properties and equipment material to the conduct of
its business in good repair, working order and condition, normal wear and tear
and casualty and condemnation excepted, and will make, or cause to be made, in
such properties and equipment from time to time all repairs, renewals,
replacements, extensions, additions, betterments and improvements thereto as may

similar businesses.

         7.8      PERFORMANCE OF OBLIGATIONS.

         Each Credit Party will, and will cause each of its Subsidiaries to,

         7.9      USE OF PROCEEDS.

or photographs thereof and to write down and record any information such
representative obtains and shall permit the Administrative Agent or its
representatives to investigate and verify the accuracy of information provided
to the Lenders and to discuss all such matters with the officers, employees and
representatives of such Person. The Credit Parties agree that the Administrative
Agent and its representatives may conduct an annual audit of the Collateral at
the expense of the Credit Parties; provided, however, upon the occurrence and
during the continuance of an Event of Default, the Administrative Agent and its
representatives may conduct an audit of the Collateral at any time and from time

Person will cause to be delivered to the Administrative Agent, with respect to
such real property, documents, instruments and other items of the types required

its Subsidiaries to, take such action (including but not limited to the actions
set forth in Sections 5.1(d) and (e)) at its own expense as requested by the
Administrative Agent to ensure that the Administrative Agent has a first
priority perfected Lien to secure the Credit Party Obligations in (i) all owned
real property and personal property of the Credit Parties located in the United
States, (ii) to the extent deemed to be material by the Administrative Agent or
the Required Lenders in its or their sole reasonable discretion, all other owned
real and personal property of the Credit Parties and (iii) all leased real
property located in the United States, subject in each case only to Permitted
Liens. Each Credit Party shall, and shall cause each of its Subsidiaries to,
adhere to the covenants regarding the location of personal property as set forth
in the Security Agreement.

         7.14     YEAR 2000 COMPLIANCE.

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

                  (a)      Fiscal Year. On or prior to March 31, 1999, the

                           (i)      default in the payment when due of any

                  obligations arising from drawings under Letters of Credit, or

                           (ii)     default, and such default shall continue for

                  Credit Documents or in connection herewith or therewith; or

                  (b)      Representations. Any representation, warranty or
         statement made or deemed to be made by any Credit Party herein, in any
         of the other Credit Documents, or in any statement or certificate
         delivered or required to be delivered pursuant hereto or thereto shall

                  unremedied for a period of at least 5 days after the earlier

                  such default or notice thereof by the Administrative Agent; or

                           (iii)    default in the due performance or observance

                  Section 9.1) contained in this Credit Agreement or any other
                  Credit Document and such default shall continue unremedied for
                  a period of at least 30 days after the earlier of a

         connection with a dissolution, merger or disposition of a Subsidiary
         permitted under Section 8.4 or Section 8.5, any Credit Document shall
         fail to be in full force and effect or to give the Administrative Agent
         and/or the Lenders the Liens, rights, powers and privileges purported
         to be created thereby, or any Credit Party shall so state in writing;
         or

                  (e)      Guaranties. Except as the result of or in connection
         with a dissolution, merger or disposition of a Subsidiary permitted
         under Section 8.4 or Section 8.5, the guaranty given by any Guarantor
         hereunder (including any Person after the Closing Date in accordance
         with Section 7.12) or any provision thereof shall cease to be in full
         force and effect, or any Guarantor (including any Person after the
         Closing Date in accordance with Section 7.12) hereunder or any Person
         acting by or on behalf of such Guarantor shall deny or disaffirm such
         Guarantor's obligations under such guaranty, or any Guarantor shall
         default in the due performance or observance of any term, covenant or
         agreement on its part to be performed or observed pursuant to any

                           (i)      Any Consolidated Party shall default in the
                  performance or observance (beyond the applicable grace period
                  with respect thereto, if any) of any obligation or condition
                  of any contract or lease material to the Consolidated Parties
                  taken as a whole, which default could reasonably have a
                  Material Adverse Effect; or

                           (ii)     With respect to any Indebtedness (other than
                  Indebtedness outstanding under this Credit Agreement) in
                  excess of $500,000 in the aggregate for the Consolidated
                  Parties taken as a whole, (A) any Consolidated Party shall (1)
                  default in any payment (beyond the applicable grace period
                  with respect thereto, if any) with respect to any such
                  Indebtedness, or (2) the occurrence and continuance of a
                  default in the observance or performance relating to such
                  Indebtedness or contained in any instrument or agreement
                  evidencing, securing or relating thereto, or any other event
                  or condition shall occur or condition exist, the effect of
                  which default or other event or condition is to cause, or
                  permit, the holder or holders of such Indebtedness (or trustee
                  or agent on behalf of such holders) to cause (determined
                  without regard to whether any notice or lapse of time is
                  required), any such Indebtedness to become due prior to its
                  stated maturity; or (B) any such Indebtedness shall be
                  declared due and payable, or required to be prepaid other than
                  by a regularly scheduled required prepayment, prior to the
                  stated maturity thereof; or

                  (h)      Judgments. One or more judgments or decrees shall be
         entered against one or more of the Consolidated Parties involving a
         liability of $500,000 or more in the aggregate (to the extent not paid
         or fully covered by insurance provided by a carrier who has
         acknowledged coverage and has the ability to perform) and any such
         judgments or decrees shall not have been vacated, discharged or stayed
         or bonded pending appeal within 30 days from the entry thereof; or

                  (i)      ERISA. Any of the following events or conditions, if
         such event or condition could have a Material Adverse Effect: (i) any
         "accumulated funding deficiency," as such term is defined in Section
         302 of ERISA and Section 412 of the Code, whether or not waived, shall
         exist with respect to any Plan, or any lien shall arise on the assets
         of any Consolidated Party or any ERISA Affiliate in favor of the PBGC
         or a Plan; (ii) an ERISA Event shall occur with respect to a Single
         Employer Plan, which is, in the reasonable opinion of the
         Administrative Agent, likely to result in the termination of such Plan
         for purposes of Title IV of ERISA; (iii) an ERISA Event shall occur
         with respect to a Multiemployer Plan or Multiple Employer Plan, which
         is, in the reasonable opinion of the Administrative Agent, likely to
         result in (A) the termination of such Plan for purposes of Title IV of
         ERISA, or (B) any Consolidated Party or any ERISA Affiliate incurring
         any liability in connection with a withdrawal from, reorganization of
         (within the meaning of Section 4241 of ERISA), or insolvency or (within
         the meaning of Section 4245 of ERISA) such Plan; or (iv) any prohibited
         transaction (within the meaning of Section 406 of ERISA or Section 4975
         of the Code) or breach of fiduciary responsibility shall occur which
         may subject any Consolidated Party or any ERISA Affiliate to any
         liability under Sections 406, 409, 502(i), or 502(l) of ERISA or
         Section 4975 of the Code, or under any agreement or other instrument
         pursuant to which any Consolidated Party or any ERISA Affiliate has
         agreed or is required to indemnify any person against any such
         liability; or

                  (j)      Ownership. There shall occur a Change of Control.

         9.2      ACCELERATION; REMEDIES.

         Upon the occurrence of an Event of Default, and at any time thereafter
unless and until such Event of Default has been waived by the requisite Lenders
(pursuant to the voting requirements of Section 11.6) or cured to the
satisfaction of the requisite Lenders (pursuant to the voting procedures in
Section 11.6), the Administrative Agent shall, upon the request and direction of
the Required Lenders, by written notice to the Credit Parties take any of the
following actions:

                  (a)      Termination of Commitments. Declare the Commitments
         terminated whereupon the Commitments shall be immediately terminated.

                  (b)      Acceleration. Declare the unpaid principal of and any
         accrued interest in respect of all Loans, any reimbursement obligations
         arising from drawings under Letters of Credit and any and all other
         indebtedness or obligations of any and every kind owing by the Credit
         Parties to the Administrative Agent and/or any of the Lenders hereunder
         to be due whereupon the same shall be immediately due and payable
         without presentment, demand, protest or other notice of any kind, all
         of which are hereby waived by the Credit Parties.

                  (c)      Cash Collateral. Direct the Credit Parties to pay
         (and the Credit Parties agree that upon receipt of such notice, or upon
         the occurrence of an Event of Default under Section 9.1(f), they will
         immediately pay) to the Administrative Agent additional cash, to be
         held by the Administrative Agent, for the benefit of the Lenders, in a
         cash collateral account as additional security for the LOC Obligations
         in respect of subsequent drawings under all then outstanding Letters of
         Credit in an amount equal to the maximum aggregate amount which may be
         drawn under all Letters of Credits then outstanding.

                  (d)      Enforcement of Rights. Enforce any and all rights and
         interests created and existing under the Credit Documents including,
         without limitation, all rights and remedies existing under the
         Collateral Documents, all rights and remedies against a Guarantor and
         all rights of set-off.

         Notwithstanding the foregoing, if an Event of Default specified in
Section 9.1(f) shall occur with respect to the Borrower, then the Commitments
shall automatically terminate and all Loans, all reimbursement obligations
arising from drawings under Letters of Credit, all accrued interest in respect
thereof, all accrued and unpaid Fees and other indebtedness or obligations owing
to the Administrative Agent and/or any of the Lenders hereunder automatically
shall immediately become due and payable without the giving of any notice or
other action by the Administrative Agent or the Lenders.


                                   SECTION 10

                                AGENCY PROVISIONS

         10.1     APPOINTMENT, POWERS AND IMMUNITIES.

         Each Lender hereby irrevocably appoints and authorizes the
Administrative Agent to act as its agent under this Credit Agreement and the
other Credit Documents with such powers and discretion as are specifically
delegated to the Administrative Agent by the terms of this Credit Agreement and
the other Credit Documents, together with such other powers as are reasonably
incidental thereto. The Administrative Agent (which term as used in this
sentence and in Section 10.5 and the first sentence of Section 10.6 hereof shall
include its Affiliates and its own and its Affiliates' officers, directors,
employees, and agents): (a) shall not have any duties or responsibilities except
those expressly set forth in this Credit Agreement and shall not be a trustee or
fiduciary for any Lender; (b) shall not be responsible to the Lenders for any
recital, statement, representation, or warranty (whether written or oral) made
in or in connection with any Credit Document or any certificate or other
document referred to or provided for in, or received by any of them under, any
Credit Document, or for the value, validity, effectiveness, genuineness,
enforceability, or sufficiency of any Credit Document, or any other document
referred to or provided for therein or for any failure by any Credit Party or
any other Person to perform any of its obligations thereunder; (c) shall not be
responsible for or have any duty to ascertain, inquire into, or verify the
performance or observance of any covenants or agreements by any Credit Party or
the satisfaction of any condition or to inspect the property (including the
books and records) of any Credit Party or any of its Subsidiaries or Affiliates;
(d) shall not be required to initiate or conduct any litigation or collection
proceedings under any Credit Document; and (e) shall not be responsible for any
action taken or omitted to be taken by it under or in connection with any Credit
Document, except for its own gross negligence or willful misconduct. The
Administrative Agent may employ agents and attorneys-in-fact and shall not be
responsible for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.

<PAGE>   101
         10.2     RELIANCE BY ADMINISTRATIVE AGENT.

         The Administrative Agent shall be entitled to rely upon any
certification, notice, instrument, writing, or other communication (including,
without limitation, any thereof by telephone or telecopy) believed by it to be
genuine and correct and to have been signed, sent or made by or on behalf of the
proper Person or Persons, and upon advice and statements of legal counsel
(including counsel for any Credit Party), independent accountants, and other
experts selected by the Administrative Agent. The Administrative Agent may deem
and treat the payee of any Note as the holder thereof for all purposes hereof
unless and until the Administrative Agent receives and accepts an Assignment and
Acceptance executed in accordance with Section 11.3(b) hereof. As to any matters
not expressly provided for by this Credit Agreement, the Administrative Agent
shall not be required to exercise any discretion or take any action, but shall
be required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of the Required Lenders,
and such instructions shall be binding on all of the Lenders; provided, however,
that the Administrative Agent shall not be required to take any action that
exposes the Administrative Agent to personal liability or that is contrary to
any Credit Document or applicable law or unless it shall first be indemnified to
its satisfaction by the Lenders against any and all liability and expense which
may be incurred by it by reason of taking any such action.

         10.3     DEFAULTS.

         The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of a Default or Event of Default unless the
Administrative Agent has received written notice from a Lender or the a Credit
Party specifying such Default or Event of Default and stating that such notice
is a "Notice of Default". In the event that the Administrative Agent receives
such a notice of the occurrence of a Default or Event of Default, the
Administrative Agent shall give prompt notice thereof to the Lenders. The
Administrative Agent shall (subject to Section 10.2 hereof) take such action
with respect to such Default or Event of Default as shall reasonably be directed
by the Required Lenders, provided that, unless and until the Administrative
Agent shall have received such directions, the Administrative Agent may (but
shall not be obligated to) take such action, or refrain from taking such action,
with respect to such Default or Event of Default as it shall deem advisable in
the best interest of the Lenders.

         10.4     RIGHTS AS A LENDER.

         With respect to its Commitment and the Loans made by it, NationsBank
(and any successor acting as Administrative Agent) in its capacity as a Lender
hereunder shall have the same rights and powers hereunder as any other Lender
and may exercise the same as though it were not acting as the Administrative
Agent, and the term "Lender" or "Lenders" shall, unless the context otherwise
indicates, include the Administrative Agent in its individual capacity.
NationsBank (and any successor acting as Administrative Agent) and its
Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, make investments in, provide services to, and
generally engage in any kind of lending, trust, or other business with any
Credit Party or any of its Subsidiaries or Affiliates as if it were not acting
as Administrative Agent, and NationsBank (and any successor acting as
Administrative Agent) and its Affiliates may accept fees and other consideration
from any Credit Party or any of its


                                       96
<PAGE>   102
Subsidiaries or Affiliates for services in connection with this Credit Agreement
or otherwise without having to account for the same to the Lenders.

         10.5     INDEMNIFICATION.

         The Lenders agree to indemnify the Administrative Agent (to the extent
not reimbursed under Section 11.5 hereof, but without limiting the obligations
of the Credit Parties under such Section) ratably in accordance with their
respective Commitments, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses (including
attorneys' fees), or disbursements of any kind and nature whatsoever that may be
imposed on, incurred by or asserted against the Administrative Agent (including
by any Lender) in any way relating to or arising out of any Credit Document or
the transactions contemplated thereby or any action taken or omitted by the
Administrative Agent under any Credit Document; provided that no Lender shall be
liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Person to be indemnified. Without
limitation of the foregoing, each Lender agrees to reimburse the Administrative
Agent promptly upon demand for its ratable share of any costs or expenses
payable by the Credit Parties under Section 11.5, to the extent that the
Administrative Agent is not promptly reimbursed for such costs and expenses by
the Credit Parties. The agreements in this Section 10.5 shall survive the
repayment of the Loans, LOC Obligations and other obligations under the Credit
Documents and the termination of the Commitments hereunder.

         10.6     NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.

         Each Lender agrees that it has, independently and without reliance on
the Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
Credit Parties and their Subsidiaries and decision to enter into this Credit
Agreement and that it will, independently and without reliance upon the
Administrative 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
analysis and decisions in taking or not taking action under the Credit
Documents. Except for notices, reports, and other documents and information
expressly required to be furnished to the Lenders by the Administrative Agent
hereunder, the Administrative Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the affairs,
financial condition, or business of any Credit Party or any of its Subsidiaries
or Affiliates that may come into the possession of the Administrative Agent or
any of its Affiliates.

         10.7     SUCCESSOR ADMINISTRATIVE AGENT.

         The Administrative Agent may resign at any time by giving notice
thereof to the Lenders and the Credit Parties and the Administrative Agent may
be removed at any time by the Required Lenders for gross negligence or willful
misconduct in the performance of its duties hereunder. Upon any such resignation
or removal, the Required Lenders shall have the right to appoint a successor
Administrative Agent. If no successor Administrative Agent shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within thirty (30) days after the retiring Administrative Agent's giving of
notice of resignation, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent which shall be a
commercial bank organized under the laws of the United States having


                                       97
<PAGE>   103
combined capital and surplus of at least $100,000,000. Upon the acceptance of
any appointment as Administrative Agent hereunder by a successor, such successor
shall thereupon succeed to and become vested with all the rights, powers,
discretion, privileges, and duties of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. After any retiring Administrative Agent's resignation
hereunder as Administrative Agent, the provisions of this Section 10 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 Administrative Agent.

         11.2     RIGHT OF SET-OFF; ADJUSTMENTS.

         Upon the occurrence and during the continuance of any Event of Default,
each Lender (and each of its Affiliates) is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender (or any
of its Affiliates) to or for the credit or the account of any Credit Party
against any and all of the obligations of such Person now or hereafter existing
under this Credit Agreement, under the Notes, under any other Credit Document or
otherwise, irrespective of whether such Lender shall have made any demand
hereunder or thereunder and although such obligations may be unmatured. Each
Lender agrees promptly to notify any affected Credit Party after any such
set-off and application made by such Lender; provided, however, that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender under this Section 11.2 are in addition
to other rights and remedies (including, without limitation, other rights of
set-off) that such Lender may have.

         11.3     BENEFIT OF AGREEMENT.

                  (a)      This Credit Agreement shall be binding upon and inure
         to the benefit of and be enforceable by the respective successors and
         assigns of the parties hereto; provided that none of the Credit Parties
         may assign or transfer any of its interests and obligations without
         prior written consent of the Lenders; provided further that the rights
         of each Lender to transfer, assign or grant participations in its
         rights and/or obligations hereunder shall be limited as set forth in
         this Section 11.3.

                  (b)      Each Lender may assign to one or more Eligible
         Assignees all or a portion of its rights and obligations under this
         Credit Agreement (including, without limitation, all or a portion of
         its Loans, its Notes, and its Commitment); provided, however, that

                           (i)      each such assignment shall be to an Eligible
                  Assignee;

                           (ii)     except in the case of an assignment to
                  another Lender, an Affiliate of an existing Lender or any fund
                  that invests in bank loans and is advised or managed by an
                  investment advisor to an existing Lender or an assignment of
                  all of a Lender's rights and obligations under this Credit
                  Agreement, any such partial assignment shall be in an amount
                  at least equal to $5,000,000 (or, if less, the remaining
                  amount of the Commitment being assigned by such Lender) or an
                  integral multiple of $1,000,000 in excess thereof;


                                       99
<PAGE>   105
                           (iii)    each such assignment shall be of a single,
                  and not a varying, percentage of all of the assigning Lender's
                  rights and obligations under this Credit Agreement; and

                           (iv)     the parties to such assignment shall execute
                  and deliver to the Administrative Agent for its acceptance an
                  Assignment and Acceptance in the form of Exhibit 11.3(b)
                  hereto, together with any Note subject to such assignment and
                  a processing fee of $3,500.

         Upon execution, delivery, and acceptance of such Assignment and
         Acceptance, the assignee thereunder shall be a party hereto and, to the
         extent of such assignment, have the obligations, rights, and benefits
         of a Lender hereunder and the assigning Lender shall, to the extent of
         such assignment, relinquish its rights and be released from its
         obligations under this Credit Agreement. Upon the consummation of any
         assignment pursuant to this Section 11.3(b), the assignor, the
         Administrative Agent and the Credit Parties shall make appropriate
         arrangements so that, if required, new Notes are issued to the assignor
         and the assignee. If the assignee is not a United States person under
         Section 7701(a)(30) of the Code, it shall deliver to the Credit Parties
         and the Administrative Agent certification as to exemption from
         deduction or withholding of Taxes in accordance with Section 3.11.

                  (c)      The Administrative Agent shall maintain at its
         address referred to in Section 11.1 a copy of each Assignment and
         Acceptance delivered to and accepted by it and a register for the
         recordation of the names and addresses of the Lenders and the
         Commitment of, and principal amount of the Loans owing to, each Lender
         from time to time (the "Register"). The entries in the Register shall
         be conclusive and binding for all purposes, absent manifest error, and
         the Credit Parties, the Administrative Agent and the Lenders may treat
         each Person whose name is recorded in the Register as a Lender
         hereunder for all purposes of this Credit Agreement. The Register shall
         be available for inspection by the Credit Parties or any Lender at any
         reasonable time and from time to time upon reasonable prior notice. Any
         assignment of any Loan or other Credit Party Obligations shall be
         effective only upon an entry with respect thereto being made in the
         Register.

                  (d)      Upon its receipt of an Assignment and Acceptance
         executed by the parties thereto, together with any Note subject to such
         assignment and payment of the processing fee, the Administrative Agent
         shall, if such Assignment and Acceptance has been completed and is in
         substantially the form of Exhibit 11.3(b) hereto, (i) accept such
         Assignment and Acceptance, (ii) record the information contained
         therein in the Register and (iii) give prompt notice thereof to the
         parties thereto.

                  (e)      Each Lender may sell participations to one or more
         Persons in all or a portion of its rights, obligations or rights and
         obligations under this Credit Agreement (including all or a portion of
         its Commitment or its Loans); provided, however, that (i) such Lender's
         obligations under this Credit Agreement shall remain unchanged, (ii)
         such Lender shall remain solely responsible to the other parties hereto
         for the performance of such obligations, (iii) the participant shall be
         entitled to the benefit of the yield protection provisions contained in
         Sections 3.7 through 3.12, inclusive, and the right of set-off


                                      100
<PAGE>   106
         contained in Section 11.2, and (iv) the Credit Parties shall continue
         to deal solely and directly with such Lender in connection with such
         Lender's rights and obligations under this Credit Agreement, and such
         Lender shall retain the sole right to enforce the obligations of the
         Credit Parties relating to the Credit Party Obligations owing to such
         Lender and to approve any amendment, modification, or waiver of any
         provision of this Credit Agreement (other than amendments,
         modifications, or waivers decreasing the amount of principal of or the
         rate at which interest is payable on such Loans or Notes, extending any
         scheduled principal payment date or date fixed for the payment of
         interest on such Loans or Notes, or extending its Commitment).

                  (f)      Notwithstanding any other provision set forth in this
         Credit Agreement, any Lender may at any time assign and pledge all or
         any portion of its Loans and its Notes (i) to any Federal Reserve Bank
         as collateral security pursuant to Regulation A and any Operating
         Circular issued by such Federal Reserve Bank or (ii) in the case of any
         Lender which has made Delayed Draw Term Loans hereunder and is an
         investment fund, to the trustee under the indenture to which such fund
         is a party in support of its obligations to such trustee for the
         benefit of the applicable trust beneficiaries. No such assignment shall
         release the assigning Lender from its obligations hereunder.

                  (g)      Any Lender may furnish any information concerning the
         Consolidated Parties in the possession of such Lender from time to time
         to assignees and participants (including prospective assignees and
         participants), subject, however, to the provisions of Section 11.14
         hereof.

         11.4     NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Administrative Agent or any
Lender in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between the Administrative Agent or any
Lender and any of the Credit Parties shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege hereunder
or under any other Credit Document preclude any other or further exercise
thereof or the exercise of any other right, power or privilege hereunder or
thereunder. The rights and remedies provided herein are cumulative and not
exclusive of any rights or remedies which the Administrative Agent or any Lender
would otherwise have. No notice to or demand on any Credit Party in any case
shall entitle the Credit Parties to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Administrative Agent or the Lenders to any other or further action in any
circumstances without notice or demand.

         11.5     EXPENSES; INDEMNIFICATION.

                  (a)      The Credit Parties jointly and severally agree to pay
         on demand all costs and expenses of the Administrative Agent and NMS in
         connection with the negotiation, syndication, preparation, execution,
         delivery, administration, modification, and amendment of this Credit
         Agreement, the other Credit Documents, and the other documents to be
         delivered hereunder, including, without limitation, the reasonable fees
         and expenses of counsel for the Administrative Agent (including the
         cost of internal counsel) with respect thereto and with respect to
         advising the Administrative Agent as to its rights and responsibilities
         under the Credit Documents. The Credit Parties further


                                      101
<PAGE>   107
         jointly and severally agree to pay on demand all costs and expenses of
         the Administrative Agent, NMS and the Lenders, if any (including,
         without limitation, reasonable attorneys' fees and expenses and the
         cost of internal counsel), in connection with (i) the enforcement
         (whether through negotiations, legal proceedings, or otherwise) of the
         Credit Documents and the other documents to be delivered hereunder,
         (ii) any bankruptcy or insolvency proceeding of a Credit Party or any
         of its Subsidiaries and (iii) upon the occurrence and during the
         continuance of an Event of Default, any work-out, renegotiation or
         restructuring of the Credit Facilities relating to the performance of
         the Credit Parties under the Credit Documents.

                  (b)      The Credit Parties jointly and severally agree to
         indemnify and hold harmless the Administrative Agent, NMS and each
         Lender and each of their Affiliates and their respective officers,
         directors, employees, agents, and advisors (each, an "Indemnified
         Party") from and against any and all claims, damages, losses,
         liabilities, costs, and expenses (including, without limitation,
         reasonable attorneys' fees) that may be incurred by or asserted or
         awarded against any Indemnified Party, in each case arising out of or
         in connection with or by reason of (including, without limitation, in
         connection with any investigation, litigation, or proceeding or
         preparation of defense in connection therewith) the Credit Documents,
         any of the transactions contemplated herein or the actual or proposed
         use of the proceeds of the Loans, except to the extent such claim,
         damage, loss, liability, cost, or expense is found in a final,
         non-appealable judgment by a court of competent jurisdiction to have
         resulted from such Indemnified Party's gross negligence or willful
         misconduct. In the case of an investigation, litigation or other
         proceeding to which the indemnity in this Section 11.5 applies, such
         indemnity shall be effective whether or not such investigation,
         litigation or proceeding is brought by any of the Credit Parties, their
         respective directors, shareholders or creditors or an Indemnified Party
         or any other Person or any Indemnified Party is otherwise a party
         thereto and whether or not the transactions contemplated hereby are
         consummated. The Credit Parties agree not to assert any claim against
         the Administrative Agent, NMS, any Lender, any of their Affiliates, or
         any of their respective directors, officers, employees, attorneys,
         agents, and advisers, on any theory of liability, for special,
         indirect, consequential, or punitive damages arising out of or
         otherwise relating to the Credit Documents, any of the transactions
         contemplated herein or the actual or proposed use of the proceeds of
         the Loans.

                  (c)      Without prejudice to the survival of any other
         agreement of the Credit Parties hereunder, the agreements and
         obligations of the Credit Parties contained in this Section 11.5 shall
         survive the repayment of the Loans, LOC Obligations and other
         obligations under the Credit Documents and the termination of the
         Commitments hereunder.

         11.6              AMENDMENTS, WAIVERS AND CONSENTS.

         Neither this Credit Agreement nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing entered into by, or approved in writing by, the Required Lenders and the
Borrower, provided, however, that:

<PAGE>   108
                  (a)      without the consent of each Lender affected thereby,

                  any reimbursement obligation, or any portion thereof, arising
                  from drawings under Letters of Credit, or extend or waive any
                  Principal Amortization Payment of any Loan, or any portion
                  thereof,

                           (ii)     reduce the rate or extend the time of
                  payment of interest (other than as a result of waiving the
                  applicability of any post-default increase in interest rates)
                  thereon or Fees hereunder,

                           (iii)    reduce or waive the principal amount of any

                  amount thereof in effect (it being understood and agreed that
                  a waiver of any Default or Event of Default or mandatory
                  reduction in the Commitments shall not constitute a change in
                  the terms of any Commitment of any Lender),

                           (v)      except as the result of or in connection
                  with an Asset Disposition permitted by Section 8.5, release
                  all or substantially all of the Collateral,

                           (vi)     except as the result of or in connection
                  with a dissolution, merger or disposition of a Consolidated
                  Party permitted under Section 8.4, release the Borrower or
                  substantially all of the other Credit Parties from its or
                  their obligations under the Credit Documents,

                           (vii)    amend, modify or waive any provision of this

                  Borrower or all or substantially all of the other Credit
                  Parties of any of its or their rights and obligations under
                  (or in respect of) the Credit Documents except as permitted
                  thereby;

                  (b)      without the consent of the Administrative Agent, no
         provision of Section 10 may be amended;

                  (c)      without the consent of the Issuing Lender, no
         provision of Section 2.2 may be amended; and

         is entitled to vote as such Lender sees fit on any bankruptcy
         reorganization plan that affects the Loans, and each Lender

         This Credit Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be an original, but all of
which shall constitute one and the same instrument. It shall not be necessary in
making proof of this Credit Agreement to produce or account for more than one
such counterpart for each of the parties hereto. Delivery by facsimile by any of
the parties hereto of an executed counterpart of this Credit Agreement shall be

         proceedings or to otherwise proceed against any Credit Party in any
         other jurisdiction.

                  (b)      Each of the Credit Parties hereby irrevocably waives

         11.14    CONFIDENTIALITY.

         The Administrative Agent and each Lender (each, a "Lending Party")
agrees to keep confidential any information furnished or made available to it by
the Credit Parties pursuant to this Credit Agreement to the same extent that it
affords such protection to its own proprietary information; provided that
nothing herein shall prevent any Lending Party from disclosing such information

of any Lending Party, (b) to any other Person if reasonably incidental to the
administration of the Credit Facilities, (c) as required by any law, rule, or
regulation, (d) upon the order of any court or administrative agency, (e) upon
the request or demand of any regulatory agency or authority, (f) that is or
becomes available to the public or that is or becomes available to any Lending
Party other than as a result of a disclosure by any Lending Party prohibited by
this Credit Agreement, (g) in connection with any litigation to which such
Lending Party or any of its Affiliates may be a party, (h) to the extent
necessary in connection with the exercise of any remedy under this Credit
Agreement or any other Credit Document, (i) to the National Association of
Insurance Commissioners or any similar organization or any nationally recognized
rating agency that requires access to information about a Lender's investment
portfolio in connection with ratings issued with respect to such Lender, (j) to
any direct or indirect contractual counterparty in swap agreements or such
contractual counterparty's professional advisor (so long as such contractual
counterparty or professional advisor to such contractual counterparty (i) has
been approved in writing by the Borrower and (ii) agrees in a writing
enforceable by the Borrower to be bound by the provisions of this Section 11.14)
and (k) subject to provisions substantially similar to those contained in this
Section 11.14, to any actual or proposed participant or assignee.

         11.15    SOURCE OF FUNDS.

         Each of the Lenders hereby represents and warrants to the Borrower that
at least one of the following statements is an accurate representation as to the
source of funds to be used by such Lender in connection with the financing
hereunder:

                  (a)      no part of such funds constitutes assets allocated to
         any separate account maintained by such Lender in which any employee
         benefit plan (or its related trust) has any interest;

                  (b)      to the extent that any part of such funds constitutes
         assets allocated to any separate account maintained by such Lender,
         such Lender has disclosed to the Borrower the name of each employee
         benefit plan whose assets in such account exceed 10% of the total
         assets of such account as of the date of such purchase (and, for
         purposes of this subsection (b), all employee benefit plans maintained
         by the same employer or employee organization are deemed to be a single
         plan);

                  (c)      to the extent that any part of such funds constitutes
         assets of an insurance company's general account, such insurance
         company has complied with all of the requirements of the regulations
         issued under Section 401(c)(1)(A) of ERISA; or


                                      106
<PAGE>   112
                  (d)      such funds constitute assets of one or more specific
         benefit plans which such Lender has identified in writing to the
         Borrower.

As used in this Section 11.15, the terms "employee benefit plan" and "separate
account" shall have the respective meanings assigned to such terms in Section 3
of ERISA.

         11.16    CONFLICT.

         To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document, on
the other hand, this Credit Agreement shall control.

                FORM OF LEGAL OPINION (GENERAL EXTERNAL COUNSEL)



                    [Letterhead of General External Counsel]



                                February 16, 1999



To the Lenders party to the Credit
  Agreement referred to below and
  NationsBank, N.A., as Administrative
  Agent thereunder

Ladies and Gentlemen:

         We have acted as counsel to Modtech Holdings, Inc., a Delaware
corporation (the "Borrower"), Modtech, Inc., a California corporation
("Modtech"), SPI Holdings, Inc., a Colorado corporation ("SPI"), the
Subsidiaries of Modtech and SPI (together with Modtech and SPI, the
"Guarantors"; the Guarantors, together with the Borrower, individually a "Credit
Party" and collectively the "Credit Parties") in connection with the Credit
Agreement dated as of the date hereof among the Borrower, the Guarantors, the
Lenders party thereto and NationsBank, N.A., as Administrative Agent for such
Lenders (the "Credit Agreement"). We are rendering the opinions set forth herein
at the request of the Lenders in accordance with Section 5.1(c)(i) of the Credit
Agreement. Capitalized terms used herein and not otherwise defined shall have
the meanings assigned thereto in the Credit Agreement.

         In rendering this opinion, we have reviewed the following documents:

         (1)      The Credit Agreement;

         (2)      Each of the Notes;

         (3)      The Security Agreement;

         (4)      The Pledge Agreement;

         (5)      The Mortgage Instruments;

         (6)      The UCC-1 Financing Statement(s) executed by the Credit
Parties in connection with the Colorado Mortgage Instruments (the "Fixture
Financing Statements");


<PAGE>   129
         (7)      The UCC-1 Financing Statements executed by the Credit Parties
(the "Code Collateral Financing Statements" and together with the Fixture
Financing Statements, the "UCC Financing Statements") in connection with the
Security Agreement;

         The documents referenced in numbers (1) through (7) above are
collectively referred to as the "Credit Documents."

         In rendering the opinions expressed below, we have examined the
Documents and originals or copies, certified or otherwise identified to our
satisfaction, of such corporate records, agreements, documents and other
instruments, and such certificates or comparable documents of public officials
and of officers and representatives of the Credit Parties, and have made such
inquiries of such officers and representatives, as we have deemed relevant and
necessary as a basis for the opinions hereinafter set forth.

         In such examination, we have assumed the genuineness of all signatures
(other than signatures on behalf of the Credit Parties to the Documents), the
authenticity of all documents (other than the Documents) submitted to us as
originals, the conformity to original documents of documents submitted to us as
certified or photostatic copies and the authenticity of the originals of such
latter documents.

         In rendering the opinion set forth in paragraph 5 below, we have
assumed, to the extent that matters covered by such opinion would be governed by
the laws of any jurisdiction other than the State of Colorado or the United
States of America or the General Corporation Law of the State of Delaware, that
the laws of such other jurisdiction are identical to the laws of the State of
Colorado.

         The opinions set forth in paragraphs 1, 2, 3 and 4 below do not cover
the following Credit Parties: Office Master of Texas, Inc., Rosewood
Enterprises, Inc. and Trac Modular Manufacturing, Inc.

         Based on the foregoing, and subject to the qualifications stated
herein, we are of the opinion that:

         1.       Each of the Credit Parties is a corporation duly organized,
validly existing and in good standing under the laws of its state of
incorporation.

         2.       Each of the Credit Parties has the corporate power and
authority, and legal right, to own its properties and assets, to lease the
property and assets it operates as lessee and to carry on its business as now
being conducted, and is qualified to do business and in good standing in its
state of incorporation and each other jurisdiction where it is required to be
qualified and in good standing by the nature of its business.

         3.       Each of the Credit Parties has the corporate power and
authority to execute, deliver and perform each of the Documents to which it is a
party and has taken all proper and


<PAGE>   130
necessary corporate action to authorize the execution, delivery and performance
of the Documents to which it is a party.

         4.       Each of the Documents has been duly executed and delivered by
each of the Credit Parties which is a party thereto.

         5.       Each of the Documents constitutes the legal, valid and binding
obligation of each of the Credit Parties which is a party thereto, enforceable
against each such Person in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium and similar laws affecting
creditors rights and remedies generally, including (without limitation)
applicable fraudulent transfer laws, and subject, as to enforceability, to
general principles of equity including (without limitation) concepts of
materiality, reasonableness, good faith and fair dealing, and other similar
doctrines affecting the enforceability of agreements generally (regardless of
whether considered in a proceeding in equity or law).

         6.       The authorized capital stock and the issued and outstanding
shares of stock of each of the direct and indirect Subsidiaries of the Borrower
as set forth in Schedule 1 attached hereto constitute, after giving effect to
the Merger, all of the authorized, issued and outstanding shares of stock of all
of the direct and indirect Subsidiaries of the Borrower, and all of such issued
and outstanding shares of stock are owned by such Persons as set forth in such
schedule. All of the Pledged Shares (as defined in the Pledge Agreement) have
been duly authorized and validly issued and are fully paid and non-assessable.

         7.       The Pledge Agreement creates a legal, valid and enforceable
security interest in favor of the Administrative Agent in the Pledged Collateral
(as defined in the Pledge Agreement).

         8.       Assuming continued possession by the Administrative Agent of
the stock certificates representing the Pledged Shares, the Administrative
Agent's security interests in the Pledged Shares constitute first priority,
perfected security interests.

         9.       The execution, delivery and performance by each of the Credit
Parties of the Documents to which it is a party, the borrowings under the Credit
Documents, the use of the proceeds of the Loans and the consummation of the
Merger, (i) will not conflict with or violate any Colorado, Delaware corporate
or federal law or regulation, or the organic documents or bylaws or similar
documents of any Credit Party, (ii) will not be in conflict with, result in a
breach of or constitute an event of default, nor an event which, with the giving
of notice or lapse of time or both, would constitute such an event of default,
under any indenture, agreement or instrument known to us to which any Credit
Party is a party and (iii) will not result in the creation or imposition of any
Lien of any nature whatsoever upon any of the properties or assets of any Credit
Party other than Permitted Liens.

         10.      No consent, approval, waiver, license, authorization or
application or other action by or filing with any Colorado, Delaware or federal
Governmental Authority is required in


<PAGE>   131
connection with the execution, delivery or performance by any Credit Party of
the Documents to which it is a party, except for those already obtained or made.

         11.      To our knowledge, there are no judicial, administrative or
arbitration orders, awards or proceedings pending or threatened against or
affecting any Credit Party in any court or before any Governmental Authority or
arbitration board or tribunal that, if adversely determined, could reasonably
have a Material Adverse Effect.

         12.      None of the Credit Parties is an "investment company," or a
company "controlled" by an "investment company," within the meaning of the
Investment Company Act of 1940, as amended, or controlled by such a company, or
a "holding company," or a "Subsidiary company" of a "holding company," or an
"affiliate" of a "holding company" or of a "Subsidiary company," within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

         13.      The execution and delivery of the Security Agreement by each
Credit Party which is a party thereto creates a valid lien on and a security
interest in the "Collateral" (as such term is defined in the Security Agreement)
of each such Person covered thereby, to the extent the validity of a lien or
security interest in the Collateral of each such Person is covered by Article 9
of the Uniform Commercial Code (the "UCC") in effect in the State of Colorado
(the "Collateral State"), as security for the Secured Obligations referred to
therein. With respect to each Credit Party which has its chief executive offices
and/or principal place of business in the Collateral State and/or which owns
(now or hereafter) any Collateral covered by Article 9 of the UCC of the
Collateral State, the lien and security interest arising under the Security
Agreement shall be duly perfected (to the extent a lien or security interest in
Collateral owned (now or hereafter) by each such Person may be perfected by the
filing of a financing statement under the UCC of the Collateral State) by the
filing of the financing statements on Form UCC-1 in the offices in the
jurisdictions indicated on Schedule 2 for each such Person.

         No opinion is expressed herein with respect to conflicts of law, choice
of law, forum selection, severability, title to any property, the enforceability
of any indemnification or liquidated damages provision.

         The opinions herein are limited to the laws of the State of Colorado,
the General Corporation Law of the State of Delaware and the federal laws of the
United States, except to the extent that, with respect to the opinion set forth
in paragraph 5 above, we have assumed as provided above that such laws are
identical to those of the State of Colorado.

         This opinion has been rendered solely for your benefit in connection
with the transactions described above and may not be used, circulated, quoted,
relied upon or otherwise referred to for any other purpose without our prior
written consent; provided, however, that this opinion may be delivered to your
regulators, accountants, attorneys and other professional advisers and may be
used in connection with any legal or regulatory proceeding relating to the
subject matter of this opinion; provided further, that any person that becomes a
Lender pursuant to the transfer provisions of the Credit Agreement may rely upon
this opinion as if it were addressed to such person and delivered on the date
hereof.


<PAGE>   132
         This opinion speaks solely as of its date. We assume no obligation to
inform the addressee, or any other person who is entitled to rely on this
opinion, of any change in fact or law subsequent to the date hereof.

with the Borrower, individually a "Credit Party" and collectively the "Credit
Parties"), the several lenders from time to time party thereto (the "Lenders"),
and NationsBank, N.A., as administrative agent for the Lenders (in such
capacity, the "Administrative Agent").

         This opinion is being delivered at the request of the Credit Parties
pursuant to Section 5.1(c)(ii) of the Credit Agreement. Capitalized terms used
herein but not otherwise defined herein shall have the respective meanings
accorded such terms in the Credit Agreement.

         In rendering the opinions expressed below, we have examined executed

otherwise identified to our satisfaction, of such corporate records, agreements,
documents and other instruments, and such certificates or comparable documents
of public officials and of officers and/or representatives of the Company, and
have made such inquiries of such officers and/or representatives as we have

         3.       The Company has duly executed and delivered each of the

         4.       Neither the execution and delivery of the Documents by the

                    [Letterhead of Local Collateral Counsel]


                                February 16, 1999



To the Lenders party to the Credit
Agreement referred to below and
NationsBank, N.A., as Administrative
  Agent thereunder

                  Re:      Modtech Holdings, Inc.

Ladies and Gentlemen:

         We have acted as special <<STATE>> counsel to ______________, a
________ corporation (the "Company"), in connection with the Credit Agreement
dated as of February 16, 1999 (the "Credit Agreement"), among Modtech Holdings,
Inc., a Delaware corporation ("Borrower"), certain subsidiaries of the Borrower
(each a "Guarantor", and together, with the Borrower, individually a "Credit
Party and collectively the "Credit Parties"), the several Lenders from time to
time party thereto and NationsBank, N.A., as Administrative Agent
("NationsBank"), the other Credit Documents referred to and defined therein and
the transactions contemplated by the Credit Agreement and the other Credit
Documents.

         This opinion is being delivered at the request of the Credit Parties
pursuant to Section 5.1(c)(iii) of the Credit Agreement. Capitalized terms used
herein but not otherwise defined herein shall have the respective meanings
accorded such terms in the Credit Agreement.

         In rendering the opinions expressed below, we have examined executed
copies of the Credit Agreement, the Security Agreement referred to and defined
therein (the "Security Agreement") and the Mortgage Instruments referred to and
defined therein for the locations identified on Schedule 2 attached hereto (the
"<<STATE>> Mortgage Instruments") and originals or copies, certified or
otherwise identified to our satisfaction, of such corporate records, agreements,
documents and other instruments, and such certificates or comparable documents
of public officials and of officers and/or representatives of the Company, and
have made such inquiries of such officers and/or representatives as we have
deemed relevant and necessary as a basis for the opinions hereinafter set forth.


<PAGE>   138
         In such examination, we have assumed the genuineness of all signatures,
the authenticity of all documents (other than the Credit Agreement, the Security
Agreement and the <<STATE>> Mortgage Instruments) submitted to us as originals,
the conformity to original documents of documents submitted to us as certified
or photostatic copies and the authenticity of the originals of such latter
documents.

         Based on the foregoing, and subject to the qualifications stated
herein, we are of the opinion that:

         1.       The execution and delivery of the Security Agreement by the
Company creates in favor of the Administrative Agent a valid lien on and a
security interest in the "Collateral" (as such term is defined in the Security
Agreement), to the extent the validity of a lien or security interest in the
Collateral is covered by Article 9 of the Uniform Commercial Code in effect in
<<STATE>> (the "<<STATE>> UCC"), as security for the Secured Obligations
referred to therein. Assuming the filing of the financing statements on Form
UCC-1 in the offices in the jurisdictions indicated on Schedule 1, such lien and
security interest is duly perfected to the extent a lien or security interest in
the Collateral owned (now or hereafter) by the Company may be perfected by the
filing of a financing statement under the <<STATE>> UCC.

         2.       Each <<STATE>> Mortgage is in proper form for recording in the
State of <<STATE>> and upon recordation of each Mortgage Instrument, as
appropriate, such Mortgage Instrument will provide the Administrative Agent, for
the benefit of the Lenders, with a valid lien on the property described therein.

         3.       Assuming that the matter would be governed by the laws of the
State of <<STATE>>, each of the Security Agreement and the <<STATE>> Mortgage
Instruments constitutes a legal, valid and binding obligation of each Credit
Party which is a party thereto, enforceable against such Person in accordance
with its terms.

         The opinions herein are limited to the laws of <<STATE>>, and we
express no opinion as to the effect on the matters covered by this opinion of
the laws of any other jurisdiction.

         This opinion is rendered solely for your benefit in connection with the
transactions described above. This opinion may not be used or relied upon by any
other person, and may not be disclosed, quoted, filed with a governmental agency
or otherwise referred to without our prior written consent except to your bank
examiners, auditors and counsel and to prospective transferees of your interests
under the Credit Agreement and their professional advisers, or as required by
law or pursuant to legal process.

                            FORM OF PLEDGE AGREEMENT


         THIS PLEDGE AGREEMENT (this "Pledge Agreement") is entered into as of
February 16, 1999 among MODTECH HOLDINGS, INC., a Delaware corporation (the
"Borrower"), certain Subsidiaries of the Borrower (individually a "Guarantor",
and collectively the "Guarantors"; together with the Borrower, individually a
"Pledgor", and collectively the "Pledgors") and NATIONSBANK, N.A., in its
capacity as administrative agent (in such capacity, the "Administrative Agent")
for the lenders from time to time party to the Credit Agreement described below
(the "Lenders").

                                    RECITALS

         WHEREAS, pursuant to that certain Credit Agreement dated as of the date
hereof (as amended, modified, extended, renewed or replaced from time to time,
the "Credit Agreement") among the Borrower, the Guarantors, the Lenders and the
Administrative Agent, the Lenders have agreed to make Loans and issue Letters of
Credit upon the terms and subject to the conditions set forth therein; and

         WHEREAS, it is a condition precedent to the effectiveness of the Credit
Agreement and the obligations of the Lenders to make their respective Loans and
to issue Letters of Credit under the Credit Agreement that the Pledgors shall
have executed and delivered this Pledge Agreement to the Administrative Agent
for the ratable benefit of the Lenders.

         NOW, THEREFORE, in consideration of these premises and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

         1.       Definitions. Unless otherwise defined herein, capitalized
terms used herein shall have the meanings ascribed to such terms in the Credit
Agreement. For purposes of this Pledge Agreement, the term "Lender" shall
include any Affiliate of any Lender which has entered into a Hedging Agreement
with any Credit Party.

         2.       Pledge and Grant of Security Interest. To secure the prompt
payment and performance in full when due, whether by lapse of time or otherwise,
of the Pledgor Obligations (as defined in Section 3 hereof), each Pledgor hereby
pledges and assigns to the Administrative Agent, for the benefit of the Lenders,
and grants to the Administrative Agent, for the benefit of the Lenders, a
continuing security interest in any and all right, title and interest of such
Pledgor in and to the following, whether now owned or existing or owned,
acquired, or arising hereafter (collectively, the "Pledged Collateral"):

                  (a)      Pledged Shares. (i) 100% (or, if less, the full
         amount owned by such Pledgor) of the issued and outstanding shares of
         capital stock owned by such Pledgor of each domestic Subsidiary set
         forth on Schedule 2(a) attached hereto and (ii) 65% (or, if


<PAGE>   157
         less, the full amount owned by such Pledgor) of the issued and
         outstanding shares of each class of capital stock or other ownership
         interests entitled to vote (within the meaning of Treas. Reg. Section
         1.956-2(c)(2)) ("Voting Equity") and 100% (or, if less, the full amount
         owned by such Pledgor) of the issued and outstanding shares of each
         class of capital stock or other ownership interests not entitled to
         vote (within the meaning of Treas. Reg. Section 1.956-2(c)(2))
         ("Non-Voting Equity") owned by such Pledgor of each Foreign Subsidiary
         set forth on Schedule 2(a) attached hereto, in each case together with
         the certificates (or other agreements or instruments), if any,
         representing such shares, and all options and other rights, contractual
         or otherwise, with respect thereto (collectively, together with the
         shares of capital stock described in Section 2(b) and 2(c) below, the
         "Pledged Shares"), including, but not limited to, the following:

                           (y)      all shares or securities representing a
                  dividend on any of the Pledged Shares, or representing a
                  distribution or return of capital upon or in respect of the
                  Pledged Shares, or resulting from a stock split, revision,
                  reclassification or other exchange therefor, and any
                  subscriptions, warrants, rights or options issued to the
                  holder of, or otherwise in respect of, the Pledged Shares; and

                           (z)      without affecting the obligations of the
                  Pledgors under any provision prohibiting such action hereunder
                  or under the Credit Agreement, in the event of any
                  consolidation or merger involving the issuer of any Pledged
                  Shares and in which such issuer is not the surviving
                  corporation, all shares of each class of the capital stock of
                  the successor corporation formed by or resulting from such
                  consolidation or merger.

                  (b)      Additional Shares. 100% (or, if less, the full amount
         owned by such Pledgor) of the issued and outstanding shares of capital
         stock owned by such Pledgor of any Person which hereafter becomes a
         domestic Subsidiary and 65% (or, if less, the full amount owned by such
         Pledgor) of the Voting Equity and 100% (or, if less, the full amount
         owned by such Pledgor) of the Non-Voting Equity owned by such Pledgor
         of any Person which hereafter becomes a Foreign Subsidiary, including,
         without limitation, the certificates representing such shares.

                  (c)      Proceeds. All proceeds and products of the foregoing,
         however and whenever acquired and in whatever form.

         Without limiting the generality of the foregoing, it is hereby
specifically understood and agreed that a Pledgor may from time to time
hereafter deliver additional shares of stock to the Administrative Agent as
collateral security for the Pledgor Obligations. Upon delivery to the
Administrative Agent, such additional shares of stock shall be deemed to be part
of the Pledged Collateral of such Pledgor and shall be subject to the terms of
this Pledge Agreement whether or not Schedule 2(a) is amended to refer to such
additional shares.

         3.       Security for Pledgor Obligations. The security interest
created hereby in the Pledged Collateral of each Pledgor constitutes continuing
collateral security for all of the Credit


                                       2
<PAGE>   158
Party Obligations, now existing or hereafter arising pursuant to the Credit
Documents, owing from the Borrower or any other Credit Party to any Lender, any
Affiliate of a Lender or the Administrative Agent, howsoever evidenced, created,
incurred or acquired, whether primary, secondary, direct, contingent, or joint
and several, including, without limitation, all liabilities arising under
Hedging Agreements between any Pledgor and any Lender, or any Affiliate of a
Lender, and all obligations and liabilities incurred in connection with
collecting and enforcing the foregoing (collectively, the "Pledgor
Obligations").

         4.       Delivery of the Pledged Collateral. Each Pledgor hereby agrees
that:

                  (a)      Each Pledgor shall deliver to the Administrative
         Agent (i) simultaneously with or prior to the execution and delivery of
         this Pledge Agreement, all certificates representing the Pledged Shares
         of such Pledgor and (ii) promptly upon the receipt thereof by or on
         behalf of a Pledgor, all other certificates and instruments
         constituting Pledged Collateral of a Pledgor. Prior to delivery to the
         Administrative Agent, all such certificates and instruments
         constituting Pledged Collateral of a Pledgor shall be held in trust by
         such Pledgor for the benefit of the Administrative Agent pursuant
         hereto. All such certificates shall be delivered in suitable form for
         transfer by delivery or shall be accompanied by duly executed
         instruments of transfer or assignment in blank, substantially in the
         form provided in Exhibit 4(a) attached hereto.

                  (b)      Additional Securities. If such Pledgor shall receive
         by virtue of its being or having been the owner of any Pledged
         Collateral, any (i) stock certificate, including without limitation,
         any certificate representing a stock dividend or distribution in
         connection with any increase or reduction of capital, reclassification,
         merger, consolidation, sale of assets, combination of shares, stock
         splits, spin-off or split-off, promissory notes or other instrument;
         (ii) option or right, whether as an addition to, substitution for, or
         an exchange for, any Pledged Collateral or otherwise; (iii) dividends
         payable in securities; or (iv) distributions of securities in
         connection with a partial or total liquidation, dissolution or
         reduction of capital, capital surplus or paid-in surplus, then such
         Pledgor shall receive such stock certificate, instrument, option, right
         or distribution in trust for the benefit of the Administrative Agent,
         shall segregate it from such Pledgor's other property and shall deliver
         it forthwith to the Administrative Agent in the exact form received
         together with any necessary endorsement and/or appropriate stock power
         duly executed in blank, substantially in the form provided in Exhibit
         4(a), to be held by the Administrative Agent as Pledged Collateral and
         as further collateral security for the Pledgor Obligations.

                  (c)      Financing Statements. Each Pledgor shall execute and
         deliver to the Administrative Agent such UCC or other applicable
         financing statements as may be reasonably requested by the
         Administrative Agent in order to perfect and protect the security
         interest created hereby in the Pledged Collateral of such Pledgor.

         5.       Representations and Warranties. Each Pledgor hereby represents
and warrants to the Administrative Agent, for the benefit of the Lenders, that
so long as any of the Pledgor Obligations remain outstanding or any Credit
Document or any Hedging Agreement between any


                                       3
<PAGE>   159
Pledgor and any Lender, or any Affiliate of a Lender, is in effect or any Letter
of Credit shall remain outstanding, and until all of the Commitments shall have
been terminated:

                  (a)      Authorization of Pledged Shares. The Pledged Shares
         are duly authorized and validly issued, are fully paid and
         nonassessable and are not subject to the preemptive rights of any
         Person. All other shares of stock constituting Pledged Collateral will
         be duly authorized and validly issued, fully paid and nonassessable and
         not subject to the preemptive rights of any Person.

                  (b)      Title. Each Pledgor has good and indefeasible title
         to the Pledged Collateral of such Pledgor and will at all times be the
         legal and beneficial owner of such Pledged Collateral free and clear of
         any Lien, other than Permitted Liens. There exists no "adverse claim"
         within the meaning of Section 8-302 of the Uniform Commercial Code as
         in effect in the State of North Carolina as of the date hereof (the
         "UCC") with respect to the Pledged Shares of such Pledgor.

                  (c)      Exercising of Rights. The exercise by the
         Administrative Agent of its rights and remedies hereunder will not
         violate any law or governmental regulation or any material contractual
         restriction binding on or affecting a Pledgor or any of its property.

                  (d)      Pledgor's Authority. No authorization, approval or
         action by, and no notice or filing with any Governmental Authority or
         with the issuer of any Pledged Stock is required either (i) for the
         pledge made by a Pledgor or for the granting of the security interest
         by a Pledgor pursuant to this Pledge Agreement or (ii) for the exercise
         by the Administrative Agent or the Lenders of their rights and remedies
         hereunder (except as may be required by laws affecting the offering and
         sale of securities).

                  (e)      Security Interest/Priority. This Pledge Agreement
         creates a valid security interest in favor of the Administrative Agent
         for the benefit of the Lenders, in the Pledged Collateral. The taking
         possession by the Administrative Agent of the certificates representing
         the Pledged Shares and all other certificates and instruments
         constituting Pledged Collateral will perfect and establish the first
         priority of the Administrative Agent's security interest in the Pledged
         Shares and, when properly perfected by filing or registration, in all
         other Pledged Collateral represented by such Pledged Shares and
         instruments securing the Pledgor Obligations. Except as set forth in
         this Section 5(e), no action is necessary to perfect or otherwise
         protect such security interest.

                  (f)      No Other Shares. No Pledgor owns any shares of stock
         other than as set forth on Schedule 2(a) attached hereto.

         6.       Covenants. Each Pledgor hereby covenants, that so long as any
of the Pledgor Obligations remain outstanding or any Credit Document or Hedging
Agreement between any Pledgor and any Lender, or any Affiliate of a Lender, is
in effect or any Letter of Credit shall remain outstanding, and until all of the
Commitments shall have been terminated, such Pledgor shall:


                                       4
<PAGE>   160
                  (a)      Books and Records. Mark its books and records (and
         shall cause the issuer of the Pledged Shares of such Pledgor to mark
         its books and records) to reflect the security interest granted to the
         Administrative Agent, for the benefit of the Lenders, pursuant to this
         Pledge Agreement.

                  (b)      Defense of Title. Warrant and defend title to and
         ownership of the Pledged Collateral of such Pledgor at its own expense
         against the claims and demands of all other parties claiming an
         interest therein, keep the Pledged Collateral free from all Liens,
         except for Permitted Liens, and not sell, exchange, transfer, assign,
         lease or otherwise dispose of Pledged Collateral of such Pledgor or any
         interest therein, except as permitted under the Credit Agreement and
         the other Credit Documents.

                  (c)      Further Assurances. Promptly execute and deliver at
         its expense all further instruments and documents and take all further
         action that may be necessary and desirable or that the Administrative
         Agent may reasonably request in order to (i) perfect and protect the
         security interest created hereby in the Pledged Collateral of such
         Pledgor (including without limitation any and all action necessary to
         satisfy the Administrative Agent that the Administrative Agent has
         obtained a first priority perfected security interest in any capital
         stock); (ii) enable the Administrative Agent to exercise and enforce
         its rights and remedies hereunder in respect of the Pledged Collateral
         of such Pledgor; and (iii) otherwise effect the purposes of this Pledge
         Agreement, including, without limitation and if requested by the
         Administrative Agent, delivering to the Administrative Agent
         irrevocable proxies in respect of the Pledged Collateral of such
         Pledgor.

                  (d)      Amendments. Not make or consent to any amendment or
         other modification or waiver with respect to any of the Pledged
         Collateral of such Pledgor or enter into any agreement or allow to
         exist any restriction with respect to any of the Pledged Collateral of
         such Pledgor other than pursuant hereto or as may be permitted under
         the Credit Agreement.

                  (e)      Compliance with Securities Laws. File all reports and
         other information now or hereafter required to be filed by such Pledgor
         with the United States Securities and Exchange Commission and any other
         state, federal or foreign agency in connection with the ownership of
         the Pledged Collateral of such Pledgor.

         7.       Advances by Lenders. On failure of any Pledgor to perform any
of the covenants and agreements contained herein, the Administrative Agent may,
at its sole option and in its sole discretion, perform the same and in so doing
may expend such sums as the Administrative Agent may reasonably deem advisable
in the performance thereof, including, without limitation, the payment of any
insurance premiums, the payment of any taxes, a payment to obtain a release of a
Lien or potential Lien, expenditures made in defending against any adverse claim
and all other expenditures which the Administrative Agent or the Lenders may
make for the protection of the security hereof or which may be compelled to make
by operation of law. All such sums and amounts so expended shall be repayable by
the Pledgors on a joint and several basis promptly upon timely notice thereof
and demand therefor, shall constitute additional Pledgor Obligations and shall
bear interest from the date said amounts are expended at the default rate
specified in Section 3.1 of


                                       5
<PAGE>   161
the Credit Agreement for Revolving Loans that are Base Rate Loans. No such
performance of any covenant or agreement by the Administrative Agent or the
Lenders on behalf of any Pledgor, and no such advance or expenditure therefor,
shall relieve the Pledgors of any default under the terms of this Pledge
Agreement, the other Credit Documents or any Hedging Agreement between any
Pledgor and any Lender, or any Affiliate of a Lender. The Lenders may make any
payment hereby authorized in accordance with any bill, statement or estimate
procured from the appropriate public office or holder of the claim to be
discharged without inquiry into the accuracy of such bill, statement or estimate
or into the validity of any tax assessment, sale, forfeiture, tax lien, title or
claim except to the extent such payment is being contested in good faith by a
Pledgor in appropriate proceedings and against which adequate reserves are being
maintained in accordance with GAAP.

         8.       Events of Default. The occurrence of an event which under the
Credit Agreement would constitute an Event of Default shall be an Event of
Default hereunder (an "Event of Default").

         9.       Remedies.

                  (a)      General Remedies. Upon the occurrence of an Event of
         Default and during the continuation thereof, the Administrative Agent
         and the Lenders shall have, in respect of the Pledged Collateral of any
         Pledgor, in addition to the rights and remedies provided herein, in the
         Credit Documents, in the Hedging Agreements between any Pledgor and any
         Lender, or any Affiliate of a Lender, or by law, the rights and
         remedies of a secured party under the UCC or any other applicable law.

                  (b)      Sale of Pledged Collateral. Upon the occurrence of an
         Event of Default and during the continuation thereof, without limiting
         the generality of this Section and without notice, the Administrative
         Agent may, in its sole discretion, sell or otherwise dispose of or
         realize upon the Pledged Collateral, or any part thereof, in one or
         more parcels, at public or private sale, at any exchange or broker's
         board or elsewhere, at such price or prices and on such other terms as
         the Administrative Agent may deem commercially reasonable, for cash,
         credit or for future delivery or otherwise in accordance with
         applicable law. To the extent permitted by law, any Lender may in such
         event, bid for the purchase of such securities. Each Pledgor agrees
         that, to the extent notice of sale shall be required by law and has not
         been waived by such Pledgor, any requirement of reasonable notice shall
         be met if notice, specifying the place of any public sale or the time
         after which any private sale is to be made, is personally served on or
         mailed, postage prepaid, to such Pledgor, in accordance with the notice
         provisions of Section 11.1 of the Credit Agreement at least 10 days
         before the time of such sale. The Administrative Agent shall not be
         obligated to make any sale of Pledged Collateral of such Pledgor
         regardless of notice of sale having been given. The Administrative
         Agent may adjourn any public or private sale from time to time by
         announcement at the time and place fixed therefor, and such sale may,
         without further notice, be made at the time and place to which it was
         so adjourned.

                  (c)      Private Sale. Upon the occurrence of an Event of
         Default and during the continuation thereof, the Pledgors recognize
         that the Administrative Agent may deem it


                                       6
<PAGE>   162
         impracticable to effect a public sale of all or any part of the Pledged
         Shares or any of the securities constituting Pledged Collateral and
         that the Administrative Agent may, therefore, determine to make one or
         more private sales of any such securities to a restricted group of
         purchasers who will be obligated to agree, among other things, to
         acquire such securities for their own account, for investment and not
         with a view to the distribution or resale thereof. Each Pledgor
         acknowledges that any such private sale may be at prices and on terms
         less favorable to the seller than the prices and other terms which
         might have been obtained at a public sale and, notwithstanding the
         foregoing, agrees that such private sale shall be deemed to have been
         made in a commercially reasonable manner and that the Administrative
         Agent shall have no obligation to delay sale of any such securities for
         the period of time necessary to permit the issuer of such securities to
         register such securities for public sale under the Securities Act of
         1933. Each Pledgor further acknowledges and agrees that any offer to
         sell such securities which has been (i) publicly advertised on a bona
         fide basis in a newspaper or other publication of general circulation
         in the financial community of New York, New York (to the extent that
         such offer may be advertised without prior registration under the
         Securities Act of 1933), or (ii) made privately in the manner described
         above shall be deemed to involve a "public sale" under the UCC,
         notwithstanding that such sale may not constitute a "public offering"
         under the Securities Act of 1933, and the Administrative Agent may, in
         such event, bid for the purchase of such securities.

                  (d)      Retention of Pledged Collateral. In addition to the
         rights and remedies hereunder, upon the occurrence of an Event of
         Default, the Administrative Agent may, after providing the notices
         required by Section 9-505(2) of the UCC or otherwise complying with the
         requirements of applicable law of the relevant jurisdiction, retain all
         or any portion of the Pledged Collateral in satisfaction of the Pledgor
         Obligations. Unless and until the Administrative Agent shall have
         provided such notices, however, the Administrative Agent shall not be
         deemed to have retained any Pledged Collateral in satisfaction of any
         Pledgor Obligations for any reason.

                  (e)      Deficiency. In the event that the proceeds of any
         sale, collection or realization are insufficient to pay all amounts to
         which the Administrative Agent or the Lenders are legally entitled, the
         Pledgors shall be jointly and severally liable for the deficiency,
         together with interest thereon at the default rate specified in Section
         3.1 of the Credit Agreement for Revolving Loans that are Base Rate
         Loans, together with the costs of collection and the reasonable fees of
         any attorneys employed by the Administrative Agent to collect such
         deficiency. Any surplus remaining after the full payment and
         satisfaction of the Pledgor Obligations shall be returned to the
         Pledgors or to whomsoever a court of competent jurisdiction shall
         determine to be entitled thereto.

         10.      Rights of the Administrative Agent.

                  (a)      Power of Attorney. In addition to other powers of
         attorney contained herein, each Pledgor hereby designates and appoints
         the Administrative Agent, on behalf of the Lenders, and each of its
         designees or agents as attorney-in-fact of such Pledgor,


                                       7

         irrevocably and with power of substitution, with authority to take any
         or all of the following actions upon the occurrence and during the
         continuance of an Event of Default:

                           (i)      to demand, collect, settle, compromise,
                  adjust and give discharges and releases concerning the Pledged
                  Collateral of such Pledgor, all as the Administrative Agent
                  may reasonably determine;

                           (ii)     to commence and prosecute any actions at any
                  court for the purposes of collecting any of the Pledged
                  Collateral of such Pledgor and enforcing any other right in
                  respect thereof;

                           (iii)    to defend, settle or compromise any action
                  brought and, in connection therewith, give such discharge or
                  release as the Administrative Agent may deem reasonably
                  appropriate;

                           (iv)     to pay or discharge taxes, liens, security
                  interests, or other encumbrances levied or placed on or
                  threatened against the Pledged Collateral of such Pledgor;

                           (v)      to direct any parties liable for any payment
                  under any of the Pledged Collateral to make payment of any and
                  all monies due and to become due thereunder directly to the
                  Administrative Agent or as the Administrative Agent shall
                  direct;

                           (vi)     to receive payment of and receipt for any
                  and all monies, claims, and other amounts due and to become
                  due at any time in respect of or arising out of any Pledged
                  Collateral of such Pledgor;

                           (vii)    to sign and endorse any drafts, assignments,
                  proxies, stock powers, verifications, notices and other
                  documents relating to the Pledged Collateral of such Pledgor;

                           (viii)   to settle, compromise or adjust any suit,
                  action or proceeding described above and, in connection
                  therewith, to give such discharges or releases as the
                  Administrative Agent may deem reasonably appropriate;

                           (ix)     execute and deliver all assignments,
                  conveyances, statements, financing statements, renewal
                  financing statements, pledge agreements, affidavits, notices
                  and other agreements, instruments and documents that the
                  Administrative Agent may determine necessary in order to
                  perfect and maintain the security interests and liens granted
                  in this Pledge Agreement and in order to fully consummate all
                  of the transactions contemplated therein;

                           (x)      to exchange any of the Pledged Collateral of
                  such Pledgor or other property upon any merger, consolidation,
                  reorganization, recapitalization or other readjustment of the
                  issuer thereof and, in connection therewith, deposit any of
                  the


                                       8
<PAGE>   164
                  Pledged Collateral of such Pledgor with any committee,
                  depository, transfer agent, registrar or other designated
                  agency upon such terms as the Administrative Agent may
                  determine;

                           (xi)     to vote for a shareholder resolution, or to
                  sign an instrument in writing, sanctioning the transfer of any
                  or all of the Pledged Shares of such Pledgor into the name of
                  the Administrative Agent or one or more of the Lenders or into
                  the name of any transferee to whom the Pledged Shares of such
                  Pledgor or any part thereof may be sold pursuant to Section 10
                  hereof; and

                           (xii)    to do and perform all such other acts and
                  things as the Administrative Agent may reasonably deem to be
                  necessary, proper or convenient in connection with the Pledged
                  Collateral of such Pledgor.

         This power of attorney is a power coupled with an interest and shall be
         irrevocable (i) for so long as any of the Pledgor Obligations remain
         outstanding, any Credit Document or any Hedging Agreement between any
         Pledgor and any Lender, or any Affiliate of a Lender, is in effect or
         any Letter of Credit shall remain outstanding and (ii) until all of the
         Commitments shall have been terminated. The Administrative Agent shall
         be under no duty to exercise or withhold the exercise of any of the
         rights, powers, privileges and options expressly or implicitly granted
         to the Administrative Agent in this Pledge Agreement, and shall not be
         liable for any failure to do so or any delay in doing so. The
         Administrative Agent shall not be liable for any act or omission or for
         any error of judgment or any mistake of fact or law in its individual
         capacity or its capacity as attorney-in-fact except acts or omissions
         resulting from its gross negligence or willful misconduct. This power
         of attorney is conferred on the Administrative Agent solely to protect,
         preserve and realize upon its security interest in Pledged Collateral.

                  (b) Performance by the Administrative Agent of Pledgor's
         Obligations. If any Pledgor fails to perform any agreement or
         obligation contained herein, the Administrative Agent itself may
         perform, or cause performance of, such agreement or obligation, and the
         expenses of the Administrative Agent incurred in connection therewith
         shall be payable by the Pledgors on a joint and several basis pursuant
         to Section 13 hereof.

                  (c) Assignment by the Administrative Agent. The Administrative
         Agent may from time to time assign the Pledgor Obligations and any
         portion thereof and/or the Pledged Collateral and any portion thereof,
         and the assignee shall be entitled to all of the rights and remedies of
         the Administrative Agent under this Pledge Agreement in relation
         thereto.

                  (d) The Administrative Agent's Duty of Care. Other than the
         exercise of reasonable care to assure the safe custody of the Pledged
         Collateral while being held by the Administrative Agent hereunder, the
         Administrative Agent shall have no duty or liability to preserve rights
         pertaining thereto, it being understood and agreed that Pledgors shall
         be responsible for preservation of all rights in the Pledged Collateral
         of such Pledgor, and the Administrative Agent shall be relieved of all
         responsibility for


                                       9
<PAGE>   165
         Pledged Collateral upon surrendering it or tendering the surrender of
         it to the Pledgors. The Administrative Agent shall be deemed to have
         exercised reasonable care in the custody and preservation of the
         Pledged Collateral in its possession if such Pledged Collateral is
         accorded treatment substantially equal to that which the Administrative
         Agent accords its own property, which shall be no less than the
         treatment employed by a reasonable and prudent agent in the industry,
         it being understood that the Administrative Agent shall not have
         responsibility for (i) ascertaining or taking action with respect to
         calls, conversions, exchanges, maturities, tenders or other matters
         relating to any Pledged Collateral, whether or not the Administrative
         Agent has or is deemed to have knowledge of such matters; or (ii)
         taking any necessary steps to preserve rights against any parties with
         respect to any Pledged Collateral.

                  (e)      Voting Rights in Respect of the Pledged Collateral.

                           (i)      So long as no Event of Default shall have
                  occurred and be continuing, to the extent permitted by law,
                  each Pledgor may exercise any and all voting and other
                  consensual rights pertaining to the Pledged Collateral of such
                  Pledgor or any part thereof for any purpose not inconsistent
                  with the terms of this Pledge Agreement or the Credit
                  Agreement; and

                           (ii)     Upon the occurrence and during the
                  continuance of an Event of Default, all rights of a Pledgor to
                  exercise the voting and other consensual rights which it would
                  otherwise be entitled to exercise pursuant to paragraph (i) of
                  this Section shall cease and all such rights shall thereupon
                  become vested in the Administrative Agent which shall then
                  have the sole right to exercise such voting and other
                  consensual rights.

                  (f)      Dividend Rights in Respect of the Pledged Collateral.

                           (i)      So long as no Event of Default shall have
                  occurred and be continuing and subject to Section 4(b) hereof,
                  each Pledgor may receive and retain any and all dividends
                  (other than stock dividends and other dividends constituting
                  Pledged Collateral which are addressed hereinabove) or
                  interest paid in respect of the Pledged Collateral to the
                  extent they are allowed under the Credit Agreement.

                           (ii)     Upon the occurrence and during the
                  continuance of an Event of Default:

                                    (A)      all rights of a Pledgor to receive
                           the dividends and interest payments which it would
                           otherwise be authorized to receive and retain
                           pursuant to paragraph (i) of this Section shall cease
                           and all such rights shall thereupon be vested in the
                           Administrative Agent which shall then have the sole
                           right to receive and hold as Pledged Collateral such
                           dividends and interest payments; and


                                       10
<PAGE>   166
                                    (B)      all dividends and interest payments
                           which are received by a Pledgor contrary to the
                           provisions of paragraph (A) of this Section shall be
                           received in trust for the benefit of the
                           Administrative Agent, shall be segregated from other
                           property or funds of such Pledgor, and shall be
                           forthwith paid over to the Administrative Agent as
                           Pledged Collateral in the exact form received, to be
                           held by the Administrative Agent as Pledged
                           Collateral and as further collateral security for the
                           Pledgor Obligations.

                  (g)      Release of Pledged Collateral. The Administrative
         Agent may release any of the Pledged Collateral from this Pledge
         Agreement or may substitute any of the Pledged Collateral for other
         Pledged Collateral without altering, varying or diminishing in any way
         the force, effect, lien, pledge or security interest of this Pledge
         Agreement as to any Pledged Collateral not expressly released or
         substituted, and this Pledge Agreement shall continue as a first
         priority lien on all Pledged Collateral not expressly released or
         substituted.

         11.      Rights of Required Lenders. All rights of the Administrative
Agent hereunder, if not exercised by the Administrative Agent, may be exercised
by the Required Lenders.

         12.      Application of Proceeds. Upon the occurrence and during the
continuance of an Event of Default, any payments in respect of the Pledgor
Obligations and any proceeds of any Pledged Collateral, when received by the
Administrative Agent or any of the Lenders in cash or its equivalent, will be
applied in reduction of the Pledgor Obligations in the order set forth in
Section 3.15(b) of the Credit Agreement, and each Pledgor irrevocably waives the
right to direct the application of such payments and proceeds and acknowledges
and agrees that the Administrative Agent shall have the continuing and exclusive
right to apply and reapply any and all such payments and proceeds in the
Administrative Agent's sole discretion, notwithstanding any entry to the
contrary upon any of its books and records.

         13.      Costs of Counsel. At all times hereafter, the Pledgors agree
to promptly pay upon demand any and all reasonable costs and expenses of the
Administrative Agent or the Lenders, (a) as required under Section 11.5 of the
Credit Agreement and (b) as necessary to protect the Pledged Collateral or to
exercise any rights or remedies under this Pledge Agreement or with respect to
any Pledged Collateral. All of the foregoing costs and expenses shall constitute
Pledgor Obligations hereunder.

         14.      Continuing Agreement.

                  (a)      This Pledge Agreement shall be a continuing agreement
         in every respect and shall remain in full force and effect so long as
         any of the Pledgor Obligations remain outstanding or any Credit
         Document or Hedging Agreement between any Pledgor and any Lender, or
         any Affiliate of a Lender, is in effect or any Letter of Credit shall
         remain outstanding, and until all of the Commitments thereunder shall
         have terminated (other than any obligations with respect to the
         indemnities and the representations and warranties set forth in the
         Credit Documents). Upon such payment and termination, this Pledge
         Agreement shall be automatically terminated and the Administrative
         Agent and the


                                       11
<PAGE>   167
         Lenders shall, upon the request and at the expense of the Pledgors,
         forthwith release all of its liens and security interests hereunder and
         shall executed and deliver all UCC termination statements and/or other
         documents reasonably requested by the Pledgors evidencing such
         termination. Notwithstanding the foregoing all releases and indemnities
         provided hereunder shall survive termination of this Pledge Agreement.

                  (b)      This Pledge Agreement shall continue to be effective
         or be automatically reinstated, as the case may be, if at any time
         payment, in whole or in part, of any of the Pledgor Obligations is
         rescinded or must otherwise be restored or returned by the
         Administrative Agent or any Lender as a preference, fraudulent
         conveyance or otherwise under any bankruptcy, insolvency or similar
         law, all as though such payment had not been made; provided that in the
         event payment of all or any part of the Pledgor Obligations is
         rescinded or must be restored or returned, all reasonable costs and
         expenses (including without limitation any reasonable legal fees and
         disbursements) incurred by the Administrative Agent or any Lender in
         defending and enforcing such reinstatement shall be deemed to be
         included as a part of the Pledgor Obligations.

         15.      Amendments; Waivers; Modifications. This Pledge Agreement and
the provisions hereof may not be amended, waived, modified, changed, discharged
or terminated except as set forth in Section 11.6 of the Credit Agreement.

         16.      Successors in Interest. This Pledge Agreement shall create a
continuing security interest in the Collateral and shall be binding upon each
Pledgor, its successors and assigns and shall inure, together with the rights
and remedies of the Administrative Agent and the Lenders hereunder, to the
benefit of the Administrative Agent and the Lenders and their successors and
permitted assigns; provided, however, that none of the Pledgors may assign its
rights or delegate its duties hereunder without the prior written consent of
each Lender or the Required Lenders, as required by the Credit Agreement. To the
fullest extent permitted by law, each Pledgor hereby releases the Administrative
Agent and each Lender, and its successors and assigns, from any liability for
any act or omission relating to this Pledge Agreement or the Collateral, except
for any liability arising from the gross negligence or willful misconduct of the
Administrative Agent, or such Lender, or its officers, employees or agents.

         17.      Notices. All notices required or permitted to be given under
this Pledge Agreement shall be in conformance with Section 11.1 of the Credit
Agreement.

         18.      Counterparts. This Pledge Agreement may be executed in any
number of counterparts, each of which where so executed and delivered shall be
an original, but all of which shall constitute one and the same instrument. It
shall not be necessary in making proof of this Pledge Agreement to produce or
account for more than one such counterpart.

         19.      Headings. The headings of the sections and subsections hereof
are provided for convenience only and shall not in any way affect the meaning or
construction of any provision of this Pledge Agreement.

         20.      Governing Law; Submission to Jurisdiction; Venue.

                  (a)      THIS PLEDGE AGREEMENT AND THE RIGHTS AND OBLIGATIONS
         OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND
         INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NORTH CAROLINA.
         Any legal action or proceeding with respect to this Security Agreement
         may be brought in the courts of the State of North Carolina, or of the
         United States for the Western District of North Carolina, and, by
         execution and delivery of this Security Agreement, each Pledgor hereby
         irrevocably accepts for itself and in respect of its property,
         generally and unconditionally, the jurisdiction of such courts. Each
         Pledgor further irrevocably consents to the service of process out of
         any of the aforementioned courts in any such action or proceeding by
         the mailing of copies thereof by registered or certified mail, postage
         prepaid, to it at the address for notices pursuant to Section 11.1 of
         the Credit Agreement, such service to become effective 30 days after
         such mailing. Nothing herein shall affect the right of the
         Administrative Agent to serve process in any other manner permitted by
         law or to commence legal proceedings or to otherwise proceed against
         any Pledgor in any other jurisdiction.

                  (b)      Each Pledgor hereby irrevocably waives any objection
         which it may now or hereafter have to the laying of venue of any of the
         aforesaid actions or proceedings arising out of or in connection with
         this Pledge Agreement brought in the courts referred to in subsection
         (a) hereof and hereby further irrevocably waives and agrees not to
         plead or claim in any such court that any such action or proceeding
         brought in any such court has been brought in an inconvenient forum.

         21.      Waiver of Jury Trial. TO THE EXTENT PERMITTED BY APPLICABLE
LAW, EACH OF THE PARTIES TO THIS PLEDGE AGREEMENT HEREBY IRREVOCABLY WAIVES ALL
RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF
OR RELATING TO THIS PLEDGE AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         22.      Severability. If any provision of this Pledge Agreement is
determined to be illegal, invalid or unenforceable, such provision shall be
fully severable and the remaining provisions shall remain in full force and
effect and shall be construed without giving effect to the illegal, invalid or
unenforceable provisions.

         23.      Entirety. This Pledge Agreement, the other Credit Documents
and the Hedging Agreements between any Pledgor and any Lender, or any Affiliate
of a Lender, represent the entire agreement of the parties hereto and thereto,
and supersede all prior agreements and understandings, oral or written, if any,
including any commitment letters or correspondence relating to the Credit
Documents, the Hedging Agreements between any Pledgor and any Lender, or any
Affiliate of a Lender, or the transactions contemplated herein and therein.

         24.      Survival. All representations and warranties of the Pledgors
hereunder shall survive the execution and delivery of this Pledge Agreement, the
other Credit Documents and the Hedging Agreements between any Pledgor and any
Lender, or any Affiliate of a Lender, the

<PAGE>   169
delivery of the Notes and the making of the Loans and the issuance of the
Letters of Credit under the Credit Agreement.

         25.      Other Security. To the extent that any of the Pledgor
Obligations are now or hereafter secured by property other than the Pledged
Collateral (including, without limitation, real and other personal property
owned by a Pledgor), or by a guarantee, endorsement or property of any other
Person, then the Administrative Agent and the Lenders shall have the right to
proceed against such other property, guarantee or endorsement upon the
occurrence of any Event of Default, and the Administrative Agent and the Lenders
have the right, in their sole discretion, to determine which rights, security,
liens, security interests or remedies the Administrative Agent and the Lenders
shall at any time pursue, relinquish, subordinate, modify or take with respect
thereto, without in any way modifying or affecting any of them or any of the
Administrative Agent's and the Lenders' rights or the Pledgor Obligations under
this Pledge Agreement, under any other of the Credit Documents or under any
Hedging Agreement between any Pledgor and any Lender, or any Affiliate of a
Lender.

         26.      Joint and Several Obligations of Pledgors.

                  (a)      Each of the Pledgors is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the Lenders under the Credit Agreement, for the mutual
         benefit, directly and indirectly, of each of the Pledgors and in
         consideration of the undertakings of each of the Pledgors to accept
         joint and several liability for the obligations of each of them.

                  (b)      Each of the Pledgors jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Pledgors with respect to the payment and performance of all of the
         Pledgor Obligations arising under this Pledge Agreement, the other
         Credit Documents and the Hedging Agreements between any Pledgor and any
         Lender, or any Affiliate of a Lender, it being the intention of the
         parties hereto that all the Pledgor Obligations shall be the joint and
         several obligations of each of the Pledgors without preferences or
         distinction among them.

                  (c)      Notwithstanding any provision to the contrary
         contained herein, in any other of the Credit Documents or in any
         Hedging Agreement between any Pledgor and any Lender, or any Affiliate
         of a Lender, the obligations of each Guarantor under the Credit
         Agreement and the other Credit Documents shall be limited to an
         aggregate amount equal to the largest amount that would not render such
         obligations subject to avoidance under Section 548 of the Bankruptcy
         Code or any comparable provisions of any applicable state law.

                  (s)      to the extent not otherwise included, all Proceeds
                  and products of any and all of the foregoing; and

                  (t)      all other assets of such Obligor, whether tangible or
                  intangible.

         The Obligors and the Administrative Agent, on behalf of the Lenders,
hereby acknowledge and agree that the security interest created hereby in the
Collateral (i) constitutes continuing collateral security for all of the Secured
Obligations, whether now existing or hereafter arising and (ii) is not to be
construed as an assignment of any Copyrights, Copyright Licenses, Patents,
Patent Licenses, Trademarks or Trademark Licenses.

         3.       Provisions Relating to Accounts.

                  (a)      Anything herein to the contrary notwithstanding, each
         of the Obligors shall remain liable under each of the Accounts to
         observe and perform all the conditions and obligations to be observed
         and performed by it thereunder, all in accordance with the terms of any
         agreement giving rise to each such Account. Neither the Administrative
         Agent nor any Lender shall have any obligation or liability under any
         Account (or any agreement giving rise thereto) by reason of or arising
         out of this Security Agreement or the receipt by the Administrative
         Agent or any Lender of any payment relating to such Account pursuant
         hereto, nor shall the Administrative Agent or any Lender be obligated
         in any manner to perform any of the obligations of an Obligor under or
         pursuant to any Account (or any agreement giving rise thereto), to make
         any payment, to make any inquiry as to the nature or the sufficiency of
         any payment received by it or as to the sufficiency of any performance
         by any party under any Account (or any agreement giving rise thereto),
         to present or file any claim, to take any action to enforce any
         performance or to collect the payment of any amounts which may have
         been assigned to it or to which it may be entitled at any time or
         times.

                  (b)      Once during each calendar year or at any time after
         the occurrence and during the continuation of an Event of Default, the
         Administrative Agent shall have the right, but not the obligation, to
         make test verifications of the Accounts in any manner and through any
         medium that it reasonably considers advisable, and the Obligors shall
         furnish all such assistance and information as the Administrative Agent
         may require in connection with such test verifications. At any time and
         from time to time, upon the Administrative Agent's request and at the
         expense of the Obligors, the Obligors shall cause independent public
         accountants or others satisfactory to the Administrative Agent to
         furnish to the Administrative Agent reports showing reconciliations,
         aging and test verifications of, and trial balances for, the Accounts.
         The Administrative Agent in its own name or in the name of others may
         communicate with account debtors on the Accounts to verify with them to
         the Administrative Agent's satisfaction the existence, amount and terms
         of any Accounts.

         4.       Representations and Warranties. Each Obligor hereby represents
and warrants to the Administrative Agent, for the benefit of the Lenders, that
so long as any of the Secured Obligations remain outstanding or any Credit
Document or Hedging Agreement between any


                                       4
<PAGE>   179
Obligor and any Lender, or any Affiliate of a Lender, is in effect or any
Letter of Credit shall remain outstanding, and until all of the Commitments
shall have been terminated:

                  (a)      Chief Executive Office; Books & Records. Each
         Obligor's chief executive office and chief place of business is (and
         for the prior four months have been) located at the locations set forth
         on Schedule 4(a) hereto, and each Obligor keeps its books and records
         at such locations.

                  (b)      Location of Collateral. The location of all
         Collateral owned by each Obligor is as shown on Schedule 4(b) hereto.

                  (c)      Ownership. Each Obligor is the legal and beneficial
         owner of its Collateral and has the right to pledge, sell, assign or
         transfer the same. Each Obligor's legal name is as shown in this
         Security Agreement and no Obligor has in the past four months changed
         its name, been party to a merger, consolidation or other change in
         structure or used any tradename except as set forth in Schedule 4(c)
         attached hereto.

                  (d)      Security Interest/Priority. This Security Agreement
         creates a valid security interest in favor of the Administrative Agent,
         for the benefit of the Lenders, in the Collateral of such Obligor and,
         when properly perfected by filing, shall constitute a valid perfected
         security interest in such Collateral, to the extent such security can
         be perfected by filing under the UCC, free and clear of all Liens
         except for Permitted Liens.

                  (e)      Farm Products. None of the Collateral constitutes, or
         is the Proceeds of, Farm Products.

                  (f)      Accounts. (i) Each Account of the Obligors and the
         papers and documents relating thereto are genuine and in all material
         respects what they purport to be, (ii) each Account arises out of (A) a
         bona fide sale of goods sold and delivered by such Obligor (or is in
         the process of being delivered) or (B) services theretofore actually
         rendered by such Obligor to, the account debtor named therein, (iii) no
         Account of an Obligor is evidenced by any Instrument or Chattel Paper
         unless such Instrument or Chattel Paper has been theretofore endorsed
         over and delivered to the Administrative Agent and (iv) no surety bond
         was required or given in connection with any Account of an Obligor or
         the contracts or purchase orders out of which they arose.

                  (g)      Inventory. No Inventory is held by an Obligor
         pursuant to consignment, sale or return, sale on approval or similar
         arrangement.

                  (h)      Copyrights, Patents and Trademarks.

                           (i)      Schedule 1(b) hereto includes all
                  Copyrights, Copyright Licenses, Patents, Patent Licenses,
                  Trademarks and Trademark Licenses owned by the Obligors in
                  their own names as of the date hereof.


                                       5
<PAGE>   180
                           (ii)     To the best of each Obligor's knowledge,
                  each Copyright, Patent and Trademark of such Obligor is valid,
                  subsisting, unexpired, enforceable and has not been abandoned.

                           (iii)    Except as set forth in Schedule 1(b) hereto,
                  none of such Copyrights, Patents and Trademarks is the subject
                  of any licensing or franchise agreement.

                           (iv)     No holding, decision or judgment has been
                  rendered by any Governmental Authority which would limit,
                  cancel or question the validity of any Copyright, Patent or
                  Trademark.

                           (v)      No action or proceeding is pending seeking
                  to limit, cancel or question the validity of any Copyright,
                  Patent or Trademark, or which, if adversely determined, would
                  have a material adverse effect on the value of any Copyright,
                  Patent or Trademark.

                           (vi)     All applications pertaining to the
                  Copyrights, Patents and Trademarks of each Obligor have been
                  duly and properly filed, and all registrations or letters
                  pertaining to such Copyrights, Patents and Trademarks have
                  been duly and properly filed and issued, and all of such
                  Copyrights, Patents and Trademarks are valid and enforceable.

                           (vii)    No Obligor has made any assignment or
                  agreement in conflict with the security interest in the
                  Copyrights, Patents or Trademarks of each Obligor hereunder.

         5.       Covenants. Each Obligor covenants that, so long as any of the
Secured Obligations remain outstanding or any Credit Document or Hedging
Agreement between any Obligor and any Lender, or any Affiliate of a Lender, is
in effect or any Letter of Credit shall remain outstanding, and until all of the
Commitments shall have been terminated, such Obligor shall:

                  (a)      Other Liens. Defend the Collateral against the claims
         and demands of all other parties claiming an interest therein, keep the
         Collateral free from all Liens, except for Permitted Liens, and not
         sell, exchange, transfer, assign, lease or otherwise dispose of the
         Collateral or any interest therein, except as permitted under the
         Credit Agreement.

                  (b)      Preservation of Collateral. Keep the Collateral in
         good order, condition and repair and not use the Collateral in
         violation of the provisions of this Security Agreement or any other
         agreement relating to the Collateral or any policy insuring the
         Collateral or any applicable statute, law, bylaw, rule, regulation or
         ordinance.

                  (c)      Instruments/Chattel Paper. If any amount payable
         under or in connection with any of the Collateral shall be or become
         evidenced by any Instrument or Chattel Paper, immediately deliver such
         Instrument or Chattel Paper to the Administrative Agent, duly endorsed
         in a manner satisfactory to the Administrative Agent, to be held as
         Collateral pursuant to this Security Agreement.

<PAGE>   181
                  (d)      Change in Location. Not, without providing 30 days
         prior written notice to the Administrative Agent and without filing
         such amendments to any previously filed financing statements as the
         Administrative Agent may require, (a) change the location of its chief
         executive office and chief place of business (as well as its books and
         records) from the locations set forth on Schedule 4(a) hereto, (b)
         change the location of its Collateral from the locations set forth for
         such Obligor on Schedule 4(b) hereto, or (c) change its name, be party

         tradename other than as set forth on Schedule 4(c) attached hereto.

                  (e)      Inspection. Upon reasonable notice, and during
         reasonable hours, at all times allow the Administrative Agent or its
         representatives to visit and inspect the Collateral as set forth in
         Section 7.10 of the Credit Agreement.

                  (f)      Perfection of Security Interest. Execute and deliver
         to the Administrative Agent such agreements, assignments or instruments
         (including affidavits, notices, reaffirmations and amendments and
         restatements of existing documents, as the Administrative Agent may
         reasonably request) and do all such other things as the Administrative
         Agent may reasonably deem necessary or appropriate (i) to assure to the
         Administrative Agent its security interests hereunder, including (A)
         such financing statements (including renewal statements) or amendments
         thereof or supplements thereto or other instruments as the
         Administrative Agent may from time to time reasonably request in order
         to perfect and maintain the security interests granted hereunder in
         accordance with the UCC, (B) with regard to Copyrights, a Notice of
         Grant of Security Interest in Copyrights in the form of Schedule
         5(f)(i), (C) with regard to Patents, a Notice of Grant of Security
         Interest in Patents for filing with the United States Patent and
         Trademark Office in the form of Schedule 5(f)(ii) attached hereto and
         (D) with regard to Trademarks, a Notice of Grant of Security Interest
         in Trademarks for filing with the United States Patent and Trademark
         Office in the form of Schedule 5(f)(iii) attached hereto, (ii) to
         consummate the transactions contemplated hereby and (iii) to otherwise
         protect and assure the Administrative Agent of its rights and interests
         hereunder. To that end, each Obligor agrees that the Administrative
         Agent may file one or more financing statements disclosing the
         Administrative Agent's security interest in any or all of the
         Collateral of such Obligor without, to the extent permitted by law,
         such Obligor's signature thereon, and further each Obligor also hereby
         irrevocably makes, constitutes and appoints the Administrative Agent,
         its nominee or any other person whom the Administrative Agent may
         designate, as such Obligor's attorney in fact with full power and for
         the limited purpose to sign in the name of such Obligor any such
         financing statements, or amendments and supplements to financing
         statements, renewal financing statements, notices or any similar
         documents which in the Administrative Agent's reasonable discretion
         would be necessary, appropriate or convenient in order to perfect and
         maintain perfection of the security interests granted hereunder, such
         power, being coupled with an interest, being and remaining irrevocable
         so long as the Credit Agreement is in effect or any amounts payable
         thereunder or under any other Credit Document or any Letter of Credit
         or any Hedging Agreement between any Obligor and any Lender, or any
         Affiliate of a Lender, shall remain outstanding, and until all of the
         Commitments thereunder shall have terminated. Each Obligor hereby
         agrees that a carbon,


                                       7
<PAGE>   182
         photographic or other reproduction of this Security Agreement or any
         such financing statement is sufficient for filing as a financing
         statement by the Administrative Agent without notice thereof to such
         Obligor wherever the Administrative Agent may in its sole discretion
         desire to file the same. In the event for any reason the law of any
         jurisdiction other than North Carolina becomes or is applicable to the
         Collateral of any Obligor or any part thereof, or to any of the Secured
         Obligations, such Obligor agrees to execute and deliver all such
         instruments and to do all such other things as the Administrative Agent
         in its sole discretion reasonably deems necessary or appropriate to
         preserve, protect and enforce the security interests of the
         Administrative Agent under the law of such other jurisdiction (and, if
         an Obligor shall fail to do so promptly upon the request of the
         Administrative Agent, then the Administrative Agent may execute any and
         all such requested documents on behalf of such Obligor pursuant to the
         power of attorney granted hereinabove). If any Collateral is in the
         possession or control of an Obligor's agents and the Administrative
         Agent so requests, such Obligor agrees to notify such agents in writing
         of the Administrative Agent's security interest therein and, upon the
         Administrative Agent's request, instruct them to hold all such
         Collateral for the Lenders' account and subject to the Administrative
         Agent's instructions. Each Obligor agrees to mark its books and records
         to reflect the security interest of the Administrative Agent in the
         Collateral.

                  (g)      Treatment of Accounts. Not grant or extend the time
         for payment of any Account, or compromise or settle any Account for
         less than the full amount thereof, or release any person or property,
         in whole or in part, from payment thereof, or allow any credit or
         discount thereon, other than as normal and customary in the ordinary
         course of an Obligor's business.

                  (h)      Covenants Relating to Copyrights.

                           (i)      Employ the Copyright for each Work with such
                  notice of copyright as may be required by law to secure
                  copyright protection.

                           (ii)     Not do any act or knowingly omit to do any
                  act whereby any material Copyright may become invalidated and
                  (A) not do any act, or knowingly omit to do any act, whereby
                  any material Copyright may become injected into the public
                  domain; (B) notify the Administrative Agent immediately if it
                  knows, or has reason to know, that any material Copyright may
                  become injected into the public domain or of any adverse
                  determination or development (including, without limitation,
                  the institution of, or any such determination or development
                  in, any court or tribunal in the United States or any other
                  country) regarding an Obligor's ownership of any such
                  Copyright or its validity; (C) take all necessary steps as it
                  shall deem appropriate under the circumstances, to maintain
                  and pursue each application (and to obtain the relevant
                  registration) and to maintain each registration of each
                  material Copyright owned by an Obligor including, without
                  limitation, filing of applications for renewal where
                  necessary; and (D) promptly notify the Administrative Agent of
                  any material infringement of any material Copyright of an
                  Obligor of which it becomes aware and take such actions as it
                  shall reasonably deem appropriate under the circumstances to
                  protect such Copyright, including, where


                                       8
<PAGE>   183
                  appropriate, the bringing of suit for infringement, seeking
                  injunctive relief and seeking to recover any and all damages
                  for such infringement.

                           (iii)    Not make any assignment or agreement in
                  conflict with the security interest in the Copyrights of each
                  Obligor hereunder.

                  (i)      Covenants Relating to Patents and Trademarks.

                           (i)      (A) Continue to use each Trademark on each
                  and every trademark class of goods applicable to its current
                  line as reflected in its current catalogs, brochures and price
                  lists in order to maintain such Trademark in full force free
                  from any claim of abandonment for non-use, (B) maintain as in
                  the past the quality of products and services offered under
                  such Trademark, (C) employ such Trademark with the appropriate
                  notice of registration, (D) not adopt or use any mark which is
                  confusingly similar or a colorable imitation of such Trademark
                  unless the Administrative Agent, for the ratable benefit of
                  the Lenders, shall obtain a perfected security interest in
                  such mark pursuant to this Security Agreement, and (E) not
                  (and not permit any licensee or sublicensee thereof to) do any
                  act or knowingly omit to do any act whereby any Trademark may
                  become invalidated.

                           (ii)     Not do any act, or omit to do any act,
                  whereby any Patent may become abandoned or dedicated.

                           (iii)    Notify the Administrative Agent and the
                  Lenders immediately if it knows, or has reason to know, that
                  any application or registration relating to any Patent or
                  Trademark may become abandoned or dedicated, or of any adverse
                  determination or development (including, without limitation,
                  the institution of, or any such determination or development
                  in, any proceeding in the United States Patent and Trademark
                  Office or any court or tribunal in any country) regarding an
                  Obligor's ownership of any Patent or Trademark or its right to
                  register the same or to keep and maintain the same.

                           (iv)     Whenever an Obligor, either by itself or
                  through an agent, employee, licensee or designee, shall file
                  an application for the registration of any Patent or Trademark
                  with the United States Patent and Trademark Office or any
                  similar office or agency in any other country or any political
                  subdivision thereof, an Obligor shall report such filing to
                  the Administrative Agent and the Lenders within five Business
                  Days after the last day of the fiscal quarter in which such
                  filing occurs. Upon request of the Administrative Agent, an
                  Obligor shall execute and deliver any and all agreements,
                  instruments, documents and papers as the Administrative Agent
                  may request to evidence the Administrative Agent's and the
                  Lenders' security interest in any Patent or Trademark and the
                  goodwill and general intangibles of an Obligor relating
                  thereto or represented thereby.

                           (v)      Take all reasonable and necessary steps,
                  including, without limitation, in any proceeding before the
                  United States Patent and Trademark Office,


                                       9
<PAGE>   184
                  or any similar office or agency in any other country or any
                  political subdivision thereof, to maintain and pursue each
                  application (and to obtain the relevant registration) and to
                  maintain each registration of the Patents and Trademarks,
                  including, without limitation, filing of applications for
                  renewal, affidavits of use and affidavits of incontestability.

                           (vi)     Promptly notify the Administrative Agent and
                  the Lenders after it learns that any Patent or Trademark
                  included in the Collateral is infringed, misappropriated or
                  diluted by a third party and promptly sue for infringement,
                  misappropriation or dilution, to seek injunctive relief where
                  appropriate and to recover any and all damages for such
                  infringement, misappropriation or dilution, or take such other
                  actions as it shall reasonably deem appropriate under the
                  circumstances to protect such Patent or Trademark.

                           (vii)    Not make any assignment or agreement in
                  conflict with the security interest in the Patents or
                  Trademarks of each Obligor hereunder.

                  (j)      New Patents, Copyrights and Trademarks. Promptly
         provide the Administrative Agent with (i) a listing of all
         applications, if any, for new Copyrights, Patents or Trademarks
         (together with a listing of the issuance of registrations or letters on
         present applications), which new applications and issued registrations
         or letters shall be subject to the terms and conditions hereunder, and
         (ii) (A) with respect to Copyrights, a duly executed Notice of Security
         Interest in Copyrights, (B) with respect to Patents, a duly executed
         Notice of Security Interest in Patents, (C) with respect to Trademarks,
         a duly executed Notice of Security Interest in Trademarks or (D) such
         other duly executed documents as the Administrative Agent may request
         in a form acceptable to counsel for the Administrative Agent and
         suitable for recording to evidence the security interest in the
         Copyright, Patent or Trademark which is the subject of such new
         application.

                  (k)      Insurance. Insure, repair and replace the Collateral
         of such Obligor as set forth in the Credit Agreement. All insurance
         proceeds shall be subject to the security interest of the
         Administrative Agent hereunder.

         6.       Advances by Lenders. On failure of any Obligor to perform any
of the covenants and agreements contained herein, the Administrative Agent may,
at its sole option and in its sole discretion, perform the same and in so doing
may expend such sums as the Administrative Agent may reasonably deem advisable
in the performance thereof, including, without limitation, the payment of any
insurance premiums, the payment of any taxes, a payment to obtain a release of a
Lien or potential Lien, expenditures made in defending against any adverse claim
and all other expenditures which the Administrative Agent or the Lenders may
make for the protection of the security hereof or which may be compelled to make
by operation of law. All such sums and amounts so expended shall be repayable by
the Obligors on a joint and several basis promptly upon timely notice thereof
and demand therefor, shall constitute additional Secured Obligations and shall
bear interest from the date said amounts are expended at the default rate
specified in Section 3.1 of the Credit Agreement for Revolving Loans that are
Base Rate Loans. No such performance of any covenant or agreement by the
Administrative Agent or the Lenders on behalf of any Obligor, and


                                       10
<PAGE>   185
no such advance or expenditure therefor, shall relieve the Obligors of any
default under the terms of this Security Agreement, the other Credit Documents
or any Hedging Agreement between any Obligor and any Lender, or any Affiliate of
a Lender. The Lenders may make any payment hereby authorized in accordance with
any bill, statement or estimate procured from the appropriate public office or
holder of the claim to be discharged without inquiry into the accuracy of such
bill, statement or estimate or into the validity of any tax assessment, sale,
forfeiture, tax lien, title or claim except to the extent such payment is being
contested in good faith by an Obligor in appropriate proceedings and against
which adequate reserves are being maintained in accordance with GAAP.

         7.       Events of Default.

         The occurrence of an event which under the Credit Agreement would
constitute an Event of Default shall be an Event of Default hereunder (an "Event
of Default").

         8.       Remedies.

                  (a)      General Remedies. Upon the occurrence of an Event of
         Default and during continuation thereof, the Lenders shall have, in
         addition to the rights and remedies provided herein, in the Credit
         Documents, in the Hedging Agreements between any Obligor and any
         Lender, or any Affiliate of a Lender, or by law (including, but not
         limited to, the rights and remedies set forth in the Uniform Commercial
         Code of the jurisdiction applicable to the affected Collateral), the
         rights and remedies of a secured party under the UCC (regardless of
         whether the UCC is the law of the jurisdiction where the rights and
         remedies are asserted and regardless of whether the UCC applies to the
         affected Collateral), and further, the Administrative Agent may, with
         or without judicial process or the aid and assistance of others, (i)
         enter on any premises on which any of the Collateral may be located
         and, without resistance or interference by the Obligors, take
         possession of the Collateral, (ii) dispose of any Collateral on any
         such premises, (iii) require the Obligors to assemble and make
         available to the Administrative Agent at the expense of the Obligors
         any Collateral at any place and time designated by the Administrative
         Agent which is reasonably convenient to both parties, (iv) remove any
         Collateral from any such premises for the purpose of effecting sale or
         other disposition thereof, and/or (v) without demand and without
         advertisement, notice, hearing or process of law, all of which each of
         the Obligors hereby waives to the fullest extent permitted by law, at
         any place and time or times, sell and deliver any or all Collateral
         held by or for it at public or private sale, by one or more contracts,
         in one or more parcels, for cash, upon credit or otherwise, at such
         prices and upon such terms as the Administrative Agent deems advisable,
         in its sole discretion (subject to any and all mandatory legal
         requirements). In addition to all other sums due the Administrative
         Agent and the Lenders with respect to the Secured Obligations, the
         Obligors shall pay the Administrative Agent and each of the Lenders all
         reasonable documented costs and expenses incurred by the Administrative
         Agent or any such Lender, including, but not limited to, reasonable
         attorneys' fees and court costs, in obtaining or liquidating the
         Collateral, in enforcing payment of the Secured Obligations, or in the
         prosecution or defense of any action or proceeding by or against the
         Administrative Agent or the Lenders or the Obligors concerning any
         matter arising out of or connected with this Security


                                       11
<PAGE>   186
         Agreement, any Collateral or the Secured Obligations, including,
         without limitation, any of the foregoing arising in, arising under or
         related to a case under the Bankruptcy Code. To the extent the rights
         of notice cannot be legally waived hereunder, each Obligor agrees that
         any requirement of reasonable notice shall be met if such notice is
         personally served on or mailed, postage prepaid, to the Borrower in
         accordance with the notice provisions of Section 11.1 of the Credit
         Agreement at least 10 days before the time of sale or other event
         giving rise to the requirement of such notice. The Administrative Agent
         and the Lenders shall not be obligated to make any sale or other
         disposition of the Collateral regardless of notice having been given.
         To the extent permitted by law, any Lender may be a purchaser at any
         such sale. To the extent permitted by applicable law, each of the
         Obligors hereby waives all of its rights of redemption with respect to
         any such sale. Subject to the provisions of applicable law, the
         Administrative Agent and the Lenders may postpone or cause the
         postponement of the sale of all or any portion of the Collateral by
         announcement at the time and place of such sale, and such sale may,
         without further notice, to the extent permitted by law, be made at the
         time and place to which the sale was postponed, or the Administrative
         Agent and the Lenders may further postpone such sale by announcement
         made at such time and place.

                  (b)      Remedies relating to Accounts. Upon the occurrence of
         an Event of Default and during the continuation thereof, whether or not
         the Administrative Agent has exercised any or all of its rights and
         remedies hereunder, each Obligor will promptly upon request of the
         Administrative Agent instruct all account debtors to remit all payments
         in respect of Accounts to a mailing location selected by the
         Administrative Agent. In addition, the Administrative Agent or its
         designee may notify any Obligor's customers and account debtors that
         the Accounts of such Obligor have been assigned to the Administrative
         Agent or of the Administrative Agent's security interest therein, and
         may (either in its own name or in the name of an Obligor or both)
         demand, collect (including without limitation by way of a lockbox
         arrangement), receive, take receipt for, sell, sue for, compound,
         settle, compromise and give acquittance for any and all amounts due or
         to become due on any Account, and, in the Administrative Agent's
         discretion, file any claim or take any other action or proceeding to
         protect and realize upon the security interest of the Lenders in the
         Accounts. Each Obligor acknowledges and agrees that the Proceeds of its
         Accounts remitted to or on behalf of the Administrative Agent in
         accordance with the provisions hereof shall be solely for the
         Administrative Agent's own convenience and that such Obligor shall not
         have any right, title or interest in such Accounts or in any such other
         amounts except as expressly provided herein. The Administrative Agent
         and the Lenders shall have no liability or responsibility to any
         Obligor for acceptance of a check, draft or other order for payment of
         money bearing the legend "payment in full" or words of similar import
         or any other restrictive legend or endorsement or be responsible for
         determining the correctness of any remittance. Each Obligor hereby
         agrees to indemnify the Administrative Agent and the Lenders from and
         against all liabilities, damages, losses, actions, claims, judgments,
         costs, expenses, charges and reasonable attorneys' fees suffered or
         incurred by the Administrative Agent or the Lenders (each, an
         "Indemnified Party") because of the maintenance of the foregoing
         arrangements except as relating to or arising out of the gross
         negligence or willful misconduct of an Indemnified Party or its
         officers, employees or agents. In the case of any investigation,
         litigation or other proceeding, the foregoing


                                       12
<PAGE>   187
         indemnity shall be effective whether or not such investigation,
         litigation or proceeding is brought by an Obligor, its directors,
         shareholders or creditors or an Indemnified Party or any other Person
         or any other Indemnified Party is otherwise a party thereto.

                  (c)      Access. In addition to the rights and remedies
         hereunder, upon the occurrence of an Event of Default and during the
         continuance thereof, the Administrative Agent shall have the right to
         enter and remain upon the various premises of the Obligors without cost
         or charge to the Administrative Agent, and use the same, together with
         materials, supplies, books and records of the Obligors for the purpose
         of collecting and liquidating the Collateral, or for preparing for sale
         and conducting the sale of the Collateral, whether by foreclosure,
         auction or otherwise. In addition, the Administrative Agent may remove
         Collateral, or any part thereof, from such premises and/or any records
         with respect thereto, in order to effectively collect or liquidate such
         Collateral.

                  (d)      Nonexclusive Nature of Remedies. Failure by the
         Administrative Agent or the Lenders to exercise any right, remedy or
         option under this Security Agreement, any other Credit Document, any
         Hedging Agreement between any Obligor and any Lender, or any Affiliate
         of a Lender, or as provided by law, or any delay by the Administrative
         Agent or the Lenders in exercising the same, shall not operate as a
         waiver of any such right, remedy or option. No waiver hereunder shall
         be effective unless it is in writing, signed by the party against whom
         such waiver is sought to be enforced and then only to the extent
         specifically stated, which in the case of the Administrative Agent or
         the Lenders shall only be granted as provided herein. To the extent
         permitted by law, neither the Administrative Agent, the Lenders, nor
         any party acting as attorney for the Administrative Agent or the
         Lenders, shall be liable hereunder for any acts or omissions or for any
         error of judgment or mistake of fact or law other than their gross
         negligence or willful misconduct hereunder. The rights and remedies of
         the Administrative Agents and the Lenders under this Security Agreement
         shall be cumulative and not exclusive of any other right or remedy
         which the Administrative Agent or the Lenders may have.

                  (e)      Retention of Collateral. The Administrative Agent
         may, after providing the notices required by Section 9-505(2) of the
         UCC or otherwise complying with the requirements of applicable law of
         the relevant jurisdiction, to the extent the Administrative Agent is in
         possession of any of the Collateral, retain the Collateral in
         satisfaction of the Secured Obligations. Unless and until the
         Administrative Agent shall have provided such notices, however, the
         Administrative Agent shall not be deemed to have retained any
         Collateral in satisfaction of any Secured Obligations for any reason.

                  (f)      Deficiency. In the event that the proceeds of any
         sale, collection or realization are insufficient to pay all amounts to
         which the Administrative Agent or the Lenders are legally entitled, the
         Obligors shall be jointly and severally liable for the deficiency,
         together with interest thereon at the default rate specified in Section
         3.1 of the Credit Agreement for Revolving Loans that are Base Rate
         Loans, together with the costs of collection and the reasonable fees of
         any attorneys employed by the Administrative Agent to collect such
         deficiency. Any surplus remaining after the full payment and
         satisfaction of


                                       13
<PAGE>   188
         the Secured Obligations shall be returned to the Obligors or to
         whomsoever a court of competent jurisdiction shall determine to be
         entitled thereto.

         9.       Rights of the Administrative Agent.

                  (a)      Power of Attorney. In addition to other powers of
         attorney contained herein, each Obligor hereby designates and appoints
         the Administrative Agent, on behalf of the Lenders, and each of its
         designees or agents, as attorney-in-fact of such Obligor, irrevocably
         and with power of substitution, with authority to take any or all of
         the following actions upon the occurrence and during the continuance of
         an Event of Default:

                           (i)      to demand, collect, settle, compromise,
                  adjust, give discharges and releases, all as the
                  Administrative Agent may reasonably determine;

                           (ii)     to commence and prosecute any actions at any
                  court for the purposes of collecting any Collateral and
                  enforcing any other right in respect thereof;

                           (iii)    to defend, settle or compromise any action
                  brought and, in connection therewith, give such discharge or
                  release as the Administrative Agent may deem reasonably
                  appropriate;

                           (iv)     receive, open and dispose of mail addressed
                  to an Obligor and endorse checks, notes, drafts, acceptances,
                  money orders, bills of lading, warehouse receipts or other
                  instruments or documents evidencing payment, shipment or
                  storage of the goods giving rise to the Collateral of such
                  Obligor on behalf of and in the name of such Obligor, or
                  securing, or relating to such Collateral;

                           (v)      sell, assign, transfer, make any agreement
                  in respect of, or otherwise deal with or exercise rights in
                  respect of, any Collateral or the goods or services which have
                  given rise thereto, as fully and completely as though the
                  Administrative Agent were the absolute owner thereof for all
                  purposes;

                           (vi)     adjust and settle claims under any insurance
                  policy relating thereto;

                           (vii)    execute and deliver all assignments,
                  conveyances, statements, financing statements, renewal
                  financing statements, security agreements, affidavits, notices
                  and other agreements, instruments and documents that the
                  Administrative Agent may determine necessary in order to
                  perfect and maintain the security interests and liens granted
                  in this Security Agreement and in order to fully consummate
                  all of the transactions contemplated therein;


                                       14
<PAGE>   189
                           (viii)   institute any foreclosure proceedings that
                  the Administrative Agent may deem appropriate; and

                           (ix)     do and perform all such other acts and
                  things as the Administrative Agent may reasonably deem to be
                  necessary, proper or convenient in connection with the
                  Collateral.

         This power of attorney is a power coupled with an interest and shall be
         irrevocable (i) for so long as any of the Secured Obligations remain
         outstanding, any Credit Document or any Hedging Agreement between any
         Obligor and any Lender, or any Affiliate of a Lender, is in effect or
         any Letter of Credit shall remain outstanding and (ii) until all of the
         Commitments shall have been terminated. The Administrative Agent shall
         be under no duty to exercise or withhold the exercise of any of the
         rights, powers, privileges and options expressly or implicitly granted
         to the Administrative Agent in this Security Agreement, and shall not
         be liable for any failure to do so or any delay in doing so. The
         Administrative Agent shall not be liable for any act or omission or for
         any error of judgment or any mistake of fact or law in its individual
         capacity or its capacity as attorney-in-fact except acts or omissions
         resulting from its gross negligence or willful misconduct. This power
         of attorney is conferred on the Administrative Agent solely to protect,
         preserve and realize upon its security interest in the Collateral.

                  (b)      Performance by the Administrative Agent of
         Obligations. If any Obligor fails to perform any agreement or
         obligation contained herein, the Administrative Agent itself may
         perform, or cause performance of, such agreement or obligation, and the
         expenses of the Administrative Agent incurred in connection therewith
         shall be payable by the Obligors on a joint and several basis pursuant
         to Section 11 hereof.

                  (c)      Assignment by the Administrative Agent. The
         Administrative Agent may from time to time assign the Secured
         Obligations and any portion thereof and/or the Collateral and any
         portion thereof, and the assignee shall be entitled to all of the
         rights and remedies of the Administrative Agent under this Security
         Agreement in relation thereto.

                  (d)      The Administrative Agent's Duty of Care. Other than
         the exercise of reasonable care to assure the safe custody of the
         Collateral while being held by the Administrative Agent hereunder, the
         Administrative Agent shall have no duty or liability to preserve rights
         pertaining thereto, it being understood and agreed that the Obligors
         shall be responsible for preservation of all rights in the Collateral,
         and the Administrative Agent shall be relieved of all responsibility
         for the Collateral upon surrendering it or tendering the surrender of
         it to the Obligors. The Administrative Agent shall be deemed to have
         exercised reasonable care in the custody and preservation of the
         Collateral in its possession if the Collateral is accorded treatment
         substantially equal to that which the Administrative Agent accords its
         own property, which shall be no less than the treatment employed by a
         reasonable and prudent agent in the industry, it being understood that
         the Administrative Agent shall not have responsibility for taking any
         necessary steps to preserve rights against any parties with respect to
         any of the Collateral.

         10.      Application of Proceeds. Upon the occurrence and during the
continuance of an Event of Default, any payments in respect of the Secured
Obligations and any proceeds of the Collateral, when received by the
Administrative Agent or any of the Lenders in cash or its equivalent, will be
applied in reduction of the Secured Obligations in the order set forth in
Section 3.15(b) of the Credit Agreement, and each Obligor irrevocably waives the
right to direct the application of such payments and proceeds and acknowledges
and agrees that the Administrative Agent shall have the continuing and exclusive
right to apply and reapply any and all such payments and proceeds in the
Administrative Agent's sole discretion, notwithstanding any entry to the
contrary upon any of its books and records.

         11.      Costs of Counsel. If at any time hereafter, whether upon the
occurrence of an Event of Default or not, the Administrative Agent employs
counsel to prepare or consider amendments, waivers or consents with respect to
this Security Agreement, or to take action or make a response in or with respect
to any legal or arbitral proceeding relating to this Security Agreement or
relating to the Collateral, or to protect the Collateral or exercise any rights
or remedies under this Security Agreement or with respect to the Collateral,
then the Obligors agree to promptly pay upon demand any and all such reasonable
documented costs and expenses of the Administrative Agent or the Lenders, all of
which costs and expenses shall constitute Secured Obligations hereunder.

         12.      Continuing Agreement.

                  (a)      This Security Agreement shall be a continuing
         agreement in every respect and shall remain in full force and effect so
         long as any of the Secured Obligations remain outstanding or any Credit
         Document or any Hedging Agreement between any Obligor and any Lender,
         or any Affiliate of a Lender, is in effect or any Letter of Credit
         shall remain outstanding, and until all of the Commitments thereunder
         shall have terminated (other than any obligations with respect to the
         indemnities and the representations and warranties set forth in the
         Credit Documents). Upon such payment and termination, this Security
         Agreement shall be automatically terminated and the Administrative
         Agent and the Lenders shall, upon the request and at the expense of the
         Obligors, forthwith release all of its liens and security interests
         hereunder and shall execute and deliver all UCC termination statements
         and/or other documents reasonably requested by the Obligors evidencing
         such termination. Notwithstanding the foregoing all releases and
         indemnities provided hereunder shall survive termination of this
         Security Agreement.

                  (b)      This Security Agreement shall continue to be
         effective or be automatically reinstated, as the case may be, if at any
         time payment, in whole or in part, of any of the Secured Obligations is
         rescinded or must otherwise be restored or returned by the
         Administrative Agent or any Lender as a preference, fraudulent
         conveyance or otherwise under any bankruptcy, insolvency or similar
         law, all as though such payment had not been made; provided that in the
         event payment of all or any part of the Secured Obligations is
         rescinded or must be restored or returned, all reasonable costs and
         expenses (including without limitation any reasonable legal fees and
         disbursements) incurred by the Administrative Agent or any Lender in
         defending and enforcing such reinstatement shall be deemed to be
         included as a part of the Secured Obligations.

         13.      Amendments; Waivers; Modifications. This Security Agreement
and the provisions hereof may not be amended, waived, modified, changed,
discharged or terminated except as set forth in Section 11.6 of the Credit
Agreement.

         14.      Successors in Interest. This Security Agreement shall create a
continuing security interest in the Collateral and shall be binding upon each
Obligor, its successors and assigns and shall inure, together with the rights
and remedies of the Administrative Agent and the Lenders hereunder, to the
benefit of the Administrative Agent and the Lenders and their successors and
permitted assigns; provided, however, that none of the Obligors may assign its
rights or delegate its duties hereunder without the prior written consent of
each Lender or the Required Lenders, as required by the Credit Agreement. To the
fullest extent permitted by law, each Obligor hereby releases the Administrative
Agent and each Lender, and its successors and assigns, from any liability for
any act or omission relating to this Security Agreement or the Collateral,
except for any liability arising from the gross negligence or willful misconduct
of the Administrative Agent, or such Lender, or its officers, employees or
agents.

         15.      Notices. All notices required or permitted to be given under
this Security Agreement shall be in conformance with Section 11.1 of the Credit
Agreement.

         16.      Counterparts. This Security Agreement may be executed in any
number of counterparts, each of which where so executed and delivered shall be
an original, but all of which shall constitute one and the same instrument. It
shall not be necessary in making proof of this Security Agreement to produce or
account for more than one such counterpart.

         17.      Headings. The headings of the sections and subsections hereof
are provided for convenience only and shall not in any way affect the meaning or
construction of any provision of this Security Agreement.

         18.      Governing Law; Submission to Jurisdiction; Venue.

                  (a)      THIS SECURITY AGREEMENT AND THE RIGHTS AND
         OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED
         AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NORTH
         CAROLINA. Any legal action or proceeding with respect to this Security
         Agreement may be brought in the courts of the State of North Carolina,
         or of the United States for [the Western District of North Carolina],
         and, by execution and delivery of this Security Agreement, each Obligor
         hereby irrevocably accepts for itself and in respect of its property,
         generally and unconditionally, the jurisdiction of such courts. Each
         Obligor further irrevocably consents to the service of process out of
         any of the aforementioned courts in any such action or proceeding by
         the mailing of copies thereof by registered or certified mail, postage
         prepaid, to it at the address for notices pursuant to Section 11.1 of
         the Credit Agreement, such service to become effective 30 days after
         such mailing. Nothing herein shall affect the right of the
         Administrative Agent to serve process in


                                       17
<PAGE>   192
         any other manner permitted by law or to commence legal proceedings or
         to otherwise proceed against any Obligor in any other jurisdiction.

                  (b)      Each Obligor hereby irrevocably waives any objection
         which it may now or hereafter have to the laying of venue of any of the
         aforesaid actions or proceedings arising out of or in connection with
         this Security Agreement brought in the courts referred to in subsection
         (a) hereof and hereby further irrevocably waives and agrees not to
         plead or claim in any such court that any such action or proceeding
         brought in any such court has been brought in an inconvenient forum.

         19.      Waiver of Jury Trial. TO THE EXTENT PERMITTED BY APPLICABLE
LAW, EACH OF THE PARTIES TO THIS SECURITY AGREEMENT HEREBY IRREVOCABLY WAIVES
ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT
OF OR RELATING TO THIS SECURITY AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

         20.      Severability. If any provision of any of the Security
Agreement is determined to be illegal, invalid or unenforceable, such provision
shall be fully severable and the remaining provisions shall remain in full force
and effect and shall be construed without giving effect to the illegal, invalid
or unenforceable provisions.

         21.      Entirety. This Security Agreement, the other Credit Documents
and the Hedging Agreements between any Obligor and any Lender, or any Affiliate
of a Lender, represent the entire agreement of the parties hereto and thereto,
and supersede all prior agreements and understandings, oral or written, if any,
including any commitment letters or correspondence relating to the Credit
Documents, the Hedging Agreements between any Obligor and any Lender, or any
Affiliate of a Lender, or the transactions contemplated herein and therein.

         22.      Survival. All representations and warranties of the Obligors
hereunder shall survive the execution and delivery of this Security Agreement,
the other Credit Documents and the Hedging Agreements between any Obligor and
any Lender, or any Affiliate of a Lender, the delivery of the Notes and the
making of the Loans and the issuance of the Letters of Credit under the Credit
Agreement.

         23.      Other Security. To the extent that any of the Secured
Obligations are now or hereafter secured by property other than the Collateral
(including, without limitation, real property and securities owned by an
Obligor), or by a guarantee, endorsement or property of any other Person, then
the Administrative Agent and the Lenders shall have the right to proceed against
such other property, guarantee or endorsement upon the occurrence of any Event
of Default, and the Administrative Agent and the Lenders have the right, in
their sole discretion, to determine which rights, security, liens, security
interests or remedies the Administrative Agent and the Lenders shall at any time
pursue, relinquish, subordinate, modify or take with respect thereto, without in
any way modifying or affecting any of them or any of the Administrative Agent's
and the Lenders' rights or the Secured Obligations under this Security Agreement
or under any other of the Credit Documents or under any Hedging Agreement
between any Obligor and any Lender, or any Affiliate of a Lender.

         24.      Joint and Several Obligations of Obligors.

                  (a)      Each of the Obligors is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the Lenders under the Credit Agreement, for the mutual
         benefit, directly and indirectly, of each of the Obligors and in
         consideration of the undertakings of each of the Obligors to accept
         joint and several liability for the obligations of each of them.

                  (b)      Each of the Obligors jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Obligors with respect to the payment and performance of all of the
         Secured Obligations arising under this Security Agreement, the other
         Credit Documents and the Hedging Agreements between any Obligor and any
         Lender, or any Affiliate of a Lender, it being the intention of the
         parties hereto that all the Obligations shall be the joint and several
         obligations of each of the Obligors without preferences or distinction
         among them.

                  (c)      Notwithstanding any provision to the contrary
         contained herein, in any other of the Credit Documents or in any
         Hedging Agreement between any Obligor and any Lender, or any Affiliate
         of a Lender, the obligations of each Guarantor under the Credit
         Agreement and the other Credit Documents shall be limited to an
         aggregate amount equal to the largest amount that would not render such
         obligations subject to avoidance under Section 548 of the Bankruptcy
         Code or any comparable provisions of any applicable state law.

                             TERMS OF SUBORDINATION


o    The documents evidencing or governing Subordinated Indebtedness shall not
     contain any affirmative or negative covenants the breach of which would
     allow the holders to exercise remedies while Credit Party Obligations are
     outstanding.

o    Subordinated Indebtedness shall not be secured by any collateral or
     guaranteed by any entity.

o    Subordinated Indebtedness shall not be cross-defaulted to the Credit
     Agreement or any of the other Credit Documents.

o    No payments or prepayments of principal or interest on Subordinated
     Indebtedness may be made or received at any time that such payments are
     prohibited to be made under the Credit Agreement.

o    As long as any of the Credit Party Obligations are outstanding, holders of
     Subordinated Indebtedness shall have no right to exercise remedies (other
     than acceleration and demand for payment).

o    Until the date 91 days after Credit Party Obligations have been paid in
     full in cash and the Credit Agreement and the other Credit Document shall
     have terminated, holders of Subordinated Indebtedness shall not take any
     action to initiate an involuntary bankruptcy proceeding in respect of the
     Borrower.

o    The Agent (on behalf of the Lenders) shall have the right, if not exercised
     by any holder of Subordinated Indebtedness, to file proofs of claim (and
     any notice of assignment of the right to receive payments) in respect of
     the Subordinated Indebtedness of such holder to the extent not filed by
     such holder in any bankruptcy proceeding in respect of the Borrower.

o    In any bankruptcy proceeding in respect of the Borrower, the Lenders shall
     be entitled to payment in full in cash before holders of the Subordinated
     Indebtedness shall be entitled to receive any payments, property or assets
     (other than (i) debt securities that are subordinated at least to the
     extent of such Subordinated Indebtedness and (ii) equity securities that
     are not redeemable for cash, and in respect of which no cash dividends are
     payable, until the Credit Party Obligations have been paid in full in cash
     and the Credit Agreement and the other Credit Document shall have
     terminated).

o    Any payments received by a holder of the Subordinated Indebtedness in
     contravention of the foregoing subordination provisions shall be held in
     trust for the benefit of, and immediately turned over to, the Agent (on
     behalf of the Lenders).


<PAGE>   208
o    In any reorganization proceeding in respect of the Borrower, the Agent (on
     behalf of the Lenders) shall be entitled to approve (on behalf of holders
     of Subordinated Indebtedness) the use of cash collateral by Borrower.

o    Holders of Subordinated Indebtedness shall agree that, in the event that
     such holder for any reason shall be entitled shall vote consistently with
     the Lenders on any plan of reorganization or liquidation.

o    In any bankruptcy proceeding in respect of the Borrower, holders of the
     Subordinated Indebtedness shall not (i) file any motion, application or
     other pleading seeking affirmative relief, including without limitation for
     the appointment of a trustee or examiner, for the conversion of the case to
     a liquidation proceeding, for the substantive consolidation of the
     Borrower's bankruptcy case with the case of any other entity, for the
     creation of a separate official committee representing only holders of
     Subordinated Indebtedness or any other form of affirmative relief of any
     other kind or nature nor (ii) file any objection or other responsive
     pleading opposing any relief requested by the Lenders.

o    Holders of Subordinated Indebtedness shall not exercise any right of
     subrogation in respect of any of the Credit Party Obligations until the
     Credit Party Obligations have been paid in full in cash and the Credit
     Agreement and the other Credit Document shall have terminated.

o    Until the Credit Party Obligations have been paid in full in cash and the
     Credit Agreement and the other Credit Document shall have terminated, no
     material amendment or modification of the documents evidencing or governing
     Subordinated Indebtedness (including without limitation any amendment or
     modification to the subordination provisions thereof) shall be effective
     unless such amendment or modification has been approved by a requisite
     number of the Lenders.

o    Holders of Subordinated Indebtedness shall not assign any interests in
     respect of the Subordinated Indebtedness.

all payments under the Credit Agreement and the Notes in respect of the interest
assigned hereby (including, without limitation, all payments of principal,
interest and commitment fees with respect thereto) to the Assignee. The Assignor

Agreement and the Notes for periods prior to the Effective Date directly between

of which when so executed shall be deemed to be an original and all of which
