or, prior to August 29, 1996, its predecessor, the Composite Products Division
of Mobil Oil Corporation, and, at all times thereafter, Trex Company, Inc. and
its wholly-owned subsidiary. The information on the decking market presented in
this Prospectus is for the U.S. market. Trex(R) is a registered trademark of
the Company.     
 
                                  THE COMPANY
 
General
   
  The Company is the nation's largest manufacturer of non-wood decking
alternative products, which are marketed under the brand name Trex(R). Trex
Wood-Polymer(TM) lumber is a wood/plastic composite that offers an attractive
appearance and the workability of wood without wood's on-going maintenance
requirements and functional disadvantages. Trex is manufactured in a
proprietary process that combines waste wood fibers and reclaimed polyethylene
and is used primarily for residential and commercial decking. The Company
promotes Trex among consumers and contractors as a premium decking product. Net
sales of Trex increased from $0.6 million in 1992 to $46.8 million in 1998.
Income from operations increased from a loss of $5.6 million in 1992 to a
profit of $11.0 million in 1998.     
   
  Annual factory sales of residential and commercial decking in 1997 totaled
approximately $1.7 billion and approximately $200 million, respectively. This
market includes all decking products other than posts, beams and columns used
for a deck's substructure. For the seven-year period ended December 31, 1997,
factory sales of all residential decking increased at a compounded annual
growth rate of approximately 8%. In recent years, factory sales of non-wood
alternative decking products to the residential market have increased at a
compounded annual growth rate of over 25%. Although wood decking accounted for
approximately 97% of 1997 decking sales (measured by board feet of lumber),
developing consumer awareness of non-wood decking alternatives, the trend to
low-maintenance products and the decline in lumber quality and quantity have
contributed to increased sales of wood/plastic composites used for decking.
Residential decking purchases include the installation of new or replacement
decks for existing homes, construction of decks for new homes and repair of
existing decks. The Company believes that, because residential deck
construction is not primarily tied to new home activity, residential decking
sales generally have not experienced the high level of cyclicality common to
businesses in the new home construction and building materials industries.     
   
  The Company seeks to achieve sales growth in the decking market by converting
demand for wood decking products into demand for Trex. The Company intends to
continue to develop and promote the Trex brand name as a premium decking
product and to focus on the contractor-installed market segment. This segment
represents approximately 70% of the decking market (measured by board feet of
lumber) and contractors generally build larger, more elaborate residential
decks than decks built by homeowners in the "do-it-yourself" market segment.
The Company sells its products through approximately 55 wholesale distribution
locations, which in turn sell Trex to approximately 2,000 independent
contractor-oriented retailer lumber yards ("dealer outlets") across the United
States.     
 
                                       1
<PAGE>
 
 
  The Company was formed in August 1996 in a buyout (the "Acquisition") of the
assets of the Composite Products Division of Mobil Oil Corporation ("Mobil").
Mobil established the Composite Products Division in April 1992 after
purchasing the technology and related assets used to create Trex. The buyout
was led by four senior Mobil executives with over 75 years of combined
management experience.
 
Competitive Strengths
 
  The Company believes that its primary competitive strengths are the
following:
   
  Superior Product. Trex offers a number of significant advantages over wood
decking products. Trex eliminates many of wood's major functional
disadvantages, which include warping, splitting and other damage from moisture.
Trex requires no sealing to protect against moisture damage, provides a
splinter-free surface and needs no chemical treatment against insect
infestation. These features of Trex eliminate the on-going maintenance
requirements for a wood deck and make Trex less costly than wood over the life
of the deck. Like wood, Trex is slip-resistant, even when wet, can be painted
or stained and is not vulnerable to damage from ultraviolet rays. The special
characteristics of Trex, including resistance to splitting, flexibility and
ease and consistency of machining and finishing, facilitate deck installation,
reduce contractor call-back and afford customers a wide range of design
options.     
   
  Brand Name Development. The Company has invested over $10 million during the
last three years to develop Trex as a recognized brand name in the residential
and commercial decking market. The Company's marketing strategy has been to
promote Trex among consumers and contractors as a premium decking product. The
Company uses extensive print and television advertising to build brand
awareness among homeowners and commercial users and targets decking contractors
with advertisements in leading building and remodeling magazines. Brand name
recognition helps to generate demand for Trex directly among consumers and also
among distributors and dealers, who recommend Trex to contractors and other
consumers. The Company believes that its branding strategy promotes product
differentiation of Trex in a market which is not generally characterized by
brand identification and enables the Company both to command premium prices and
to maintain price stability for Trex.     
   
  Extensive Distribution Network. The Company has developed an extensive
distribution network which complements its branding strategy and focus on the
contractor-installed market segment. At December 31, 1998, the Company sold
Trex through approximately 55 wholesale distribution locations. At the same
date, the Company's distributors marketed Trex to approximately 2,000 dealer
outlets, which directly service contractors and consumers. The Company selects
distributors based upon their anticipated commitment to Trex, and the Company's
distribution network devotes significant resources to promoting and selling
Trex. All distributors have appointed a Trex specialist, regularly conduct
dealer training sessions, fund demonstration projects and participate in local
advertising campaigns and home shows. These distributors generally sell Trex as
their only non-wood decking alternative and agree in their distribution
agreements with the Company not to market other wood/plastic composites with
the same applications as Trex.     
   
  Investment in Manufacturing Process and Product Development. Production of a
non-wood decking alternative like Trex requires significant capital investment,
special process know-how and time to develop. The Company has invested
approximately $34 million and six years in expansion of its manufacturing
capacity, manufacturing process improvements, new product development and
product enhancements. The Company's investment of time and capital has enabled
it to increase the number of production lines from one to eight and its
manufacturing line production rates by more than 200% since 1992, has
facilitated the Company's development of new products and has produced
improvements in the dimensional consistency, surface texture and color
uniformity of Trex.     
 
 
                                       2
<PAGE>
 
  Building Code Listing. Trex is the only non-wood decking alternative to
receive a product building code listing either from the National Evaluation
Service (the "NES") or from any of the three NES regional members that
establish construction standards in the United States. Since receiving its NES
listing in 1995, Trex has been the only non-wood alternative decking product
published in all major code books throughout the country. The Company's listing
facilitates the acquisition of building permits by residential consumers of
Trex. The Company believes that its listing promotes customer and industry
acceptance of Trex as a substitute for wood in decking.
 
  Experienced Management Team. The Company is managed by four experienced
senior executives who led the buyout of Mobil's Composite Products Division in
1996. The Company's executives have managed billion-dollar operations as well
as smaller, high-growth divisions and product rollouts within and outside of
Mobil. They have approximately 75 years of combined management experience at
Mobil across a wide range of management functions.
 
Growth Strategies
 
  The Company's goals are to continue to be the leading producer of a superior
non-wood decking alternative product, to increase its market share of the
decking market and to expand new products and geographic markets. To attain
these goals, the Company employs the following strategies:
 
  Continue Brand Name Development. The Company plans to increase its investment
in, and the resources devoted to, development of the Trex brand. The Company's
branding efforts will focus on implementation of enhanced integrated
advertising, public relations and trade programs. The Company's sales growth in
the decking market will largely depend on converting demand for wood products
into demand for Trex. Accordingly, the Company's branding strategy will
continue to emphasize the advantages of Trex over wood decking products. The
Company's brand building programs also are designed to support the positioning
of Trex as a premium product in the decking market.
   
  Expand Distribution Coverage. The Company intends to establish comprehensive
national coverage for Trex. To achieve this objective, the Company expects to
increase the number of dealer outlets selling Trex over the next three years by
50% to approximately 3,000 outlets. The Company will seek to expand its dealer
network by adding new distributors and increasing the number of its wholesale
distribution locations to approximately 75 distribution locations from its base
of approximately 55 at December 31, 1998.     
   
  Increase Production Capacity. Currently, customer demand for Trex exceeds the
Company's manufacturing capacity. To support sales growth and improve customer
service, the Company plans to increase output by increasing productivity in its
existing facility in Winchester, Virginia and by beginning production in an
additional manufacturing facility near Reno, Nevada in the third quarter of
1999. The Company recently augmented the production capacity of its Winchester
facility by adding one new production line in December 1998 and a second new
production line in January 1999. The addition of these two production lines
will enable the Company to increase its manufacturing capacity by approximately
40% by mid-1999. With the second manufacturing facility in operation, the
Company expects by the end of 1999 to double its production capacity from the
level sustained in December 1998.     
   
  Invest in Process and Product Development. The Company will continue to make
substantial investments in process and product development to support new
products and improve product consistency, reduce manufacturing costs and
increase operating efficiencies. In the third quarter of 1998, the Company
centralized its research and development operations in the Trex Technical
Center, a 30,000-square foot building adjacent to its Winchester manufacturing
facility.

  Increase New Product Development and Export Markets. As part of its long-term
growth strategy, the Company will continue to develop opportunities for Trex in
new products and product applications and in geographic markets beyond the
Company's U.S. base. In 1998, the Company derived approximately 15% of its net
sales from sales of Trex for non-decking applications, including industrial
block flooring, applications for parks and recreational areas, floating and
fixed docks and other marine applications, and landscape edging. The Company
believes that the product characteristics of Trex are well suited to satisfy
the diverse appearance, performance and safety requirements of these and other
potential product applications. In expanding its geographic scope of
operations, the Company plans to increase exports to Canada, where it currently
has limited sales, and to explore export opportunities in the Caribbean, Latin
America and selected parts of Europe.     
 
Reorganization
 
  In connection with the Offering, the Company and Trex Company, LLC will take
certain actions described below which are collectively referred to in this
Prospectus as the "Reorganization."
   
  Trex Company, Inc. is currently a wholly-owned subsidiary of Trex Company,
LLC, a Delaware limited liability company. Prior to the consummation of the
Offering, the members of Trex Company, LLC other than Mobil will contribute
their membership interests in Trex Company, LLC to Trex Company, Inc. in
exchange for Common Stock of Trex Company, Inc. (the "Exchange Transaction").
Concurrently with such exchange, Trex Company, Inc. will purchase Mobil's
membership interest in Trex Company, LLC for $3.1 million payable upon
consummation of the Offering. As a result of the Exchange Transaction and such
purchase, Trex Company, LLC will become a wholly-owned subsidiary of Trex
Company, Inc.     
   
  In connection with the Exchange Transaction, Trex Company, LLC will make a
special cash distribution of approximately $9.3 million to certain of its
members (the "LLC Distribution"). Of the LLC Distribution, approximately $6.9
million represents the amount of the previously recognized and undistributed
taxable income of Trex Company, LLC through the expected payment date on which
the members have paid, or will pay, income tax and approximately $2.4 million
represents a return of capital. The estimated $6.9 million amount and the total
amount of the LLC Distribution are subject to adjustment based on the actual
taxable income of Trex Company, LLC from January 1, 1999 through the date of
the LLC Distribution. See "Certain Transactions--Reorganization."     
       
  The Company's principal executive offices are located at 20 South Cameron
Street, Winchester, Virginia 22601, and the Company's telephone number at that
address is (540) 678-4070.

(1)  On August 29, 1996, the Company acquired substantially all of the assets
    and assumed certain of the liabilities of the Predecessor for a purchase
    price of approximately $29.5 million. See "Certain Transactions--
    Acquisition Transactions."
   
(2)  The pro forma statement of operations data do not include adjustments to
    reflect recognition of a one-time non-cash tax charge of approximately $1.4
    million for the year ended December 31, 1998 with respect to a net deferred
    tax liability related to the Company's conversion in the Reorganization to
    a corporation taxed in accordance with Subchapter C of the Internal Revenue
    Code (a "C corporation"). Such data give effect to the conversion as if it
    had occurred on January 1, 1998. The pro forma income tax provision is
    calculated at a combined federal and state income tax rate of 40%. See
    "Management's Discussion and Analysis of Financial Condition and Results of
    Operations--Overview" and "Certain Transactions--Reorganization."
    Historical interest income has been eliminated to reflect application of
    cash balances to fund a portion of the LLC Distribution. The pro forma cash
    flow data reflect $1.0 million of the $5.6 million LLC Distribution. The
    remaining $4.6 million of the LLC Distribution will be paid from the net
    proceeds of the Offering.     
   
(3)  The pro forma, as adjusted, statement of operations data have been
    computed by eliminating interest expense of $2.8 million related to debt
    that will be repaid with a portion of the net proceeds of the Offering. The
    pro forma, as adjusted, statement of operations data do not include
    adjustments to (i) record an extraordinary loss, net of taxes, of $1.1
    million for the year ended December 31, 1998 related to the extinguishment
    of such debt or (ii) reflect recognition of a one-time non-cash tax charge
    of approximately $1.4 million for the year ended December 31, 1998 with
    respect to a net deferred

   tax liability related to the Company's conversion in the Reorganization to a
   C corporation. Such data give effect to the conversion as if it had occurred
   on January 1, 1998. The pro forma, as adjusted, income tax provision is
   calculated at a combined federal and state income tax rate of 40%. See
   "Management's Discussion and Analysis of Financial Condition and Results of
   Operations--Overview" and "Certain Transactions--Reorganization." Historical
   interest income has been eliminated to reflect application of cash balances
   to fund a portion of the LLC Distribution.     
   
(4)  For the period shown, the Predecessor was included in the consolidated tax
    return of its parent and, accordingly, no tax provision was provided. For
    all periods since inception, the Company elected to be treated as a
    partnership for federal and state income tax purposes. As a result, the
    Company's income has been taxed directly to the Company's members, rather
    than to the Company.     
   
(5)  Pro forma and pro forma, as adjusted, net income and net income per share
    reflect current federal and state income taxes (assuming a 40% combined
    effective tax rate) as if the Company had been taxed as a C corporation for
    the periods presented.     
   
(6)  Pro forma and pro forma, as adjusted, net income and net income per share
    for the year ended December 31, 1998 do not include adjustments to record
    deferred income tax expense of $1.4 million as a result of the Company's
    conversion to C corporation status in the Reorganization, as if such
    conversion had occurred on January 1, 1998.     
   
(7) Assumes 10,250,000 and 13,500,000 weighted average shares outstanding
    during the year ended December 31, 1998 on a pro forma and pro forma, as
    adjusted, basis, respectively. Diluted income per share is the same as
    basic income per share and, therefore, is not separately presented.     
   
(8)  Consists of income (loss) from operations plus depreciation and
    amortization. EBITDA is presented because it is a commonly used measure of
    performance by the financial community. Although management believes EBITDA
    is a useful measure of the Company's performance, EBITDA should not be
    considered an alternative to net income (loss) as a measure of operating
    performance or to cash provided by (used for) operating activities as a
    measure of liquidity. In addition, this measure of EBITDA may not be
    comparable to similarly titled measures reported by other companies.     
   
(9)  Reflects (i) the LLC Distribution of $5.6 million at December 31, 1998 and
    (ii) the purchase of the preferred membership interests in the Company for
    approximately $3.1 million. Does not reflect a net deferred tax liability
    of $2.4 million that would have been recorded by the Company if it had
    converted to C corporation status on December 31, 1998. The $5.6 million
    LLC Distribution adjustment is calculated as if the LLC Distribution had
    been made on December 31, 1998 and is based in part on the estimated amount
    of previously recognized and undistributed income of the Company through
    such date, while the $9.3 million LLC Distribution amount appearing
    elsewhere in this Prospectus also reflects the then estimated additional
    results of operations of the Company from January 1, 1999 through the
    estimated date of the LLC Distribution. The $5.6 million amount as of
    December 31, 1998 will be increased by the amount of any taxable income
    realized by the Company from January 1, 1999 through the date of the LLC
    Distribution. See "Certain Transactions--Reorganization."     
   
(10)  Reflects (i) the LLC Distribution of $5.6 million at December 31, 1998,
     (ii) the purchase of the preferred membership interests in the Company for
     approximately $3.1 million, (iii) a net deferred tax liability of $2.4
     million that would have been recorded by the Company if it had converted
     to C corporation status on December 31, 1998, (iv) an extraordinary $1.1
     million charge for the early extinguishment of debt to be repaid from the
     net proceeds of the Offering and (v) the sale by the Company of the Shares
     in the Offering and the application of the net proceeds therefrom. See
     "Use of Proceeds," "Capitalization," "Management's Discussion and Analysis
     of Financial Condition and Results of Operations--Overview" and "Certain
     Transactions--Reorganization."

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, investors should
carefully consider the following risk factors before deciding whether to
purchase the Shares offered hereby. Certain statements in this Prospectus
concerning the Company's future financial condition and performance are
forward-looking statements. The Company's actual results may differ materially
from those expressed in or implied by such forward-looking statements. Factors
that may cause such a difference include, but are not limited to, those
discussed below and in the sections of this Prospectus entitled "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business."
 
Ability to Increase Market Acceptance
   
  The Company's ability to grow will largely depend on its success in
converting demand for wood decking products, which accounted for approximately
97% of the 1997 decking market (measured by board feet of lumber), into demand
for Trex. The Company's strategy to increase market acceptance of Trex is to
develop and promote the Trex brand name as a premium decking product and to
emphasize the advantages of Trex over wood decking products. To increase its
market share, the Company must overcome the low consumer awareness of non-wood
decking alternatives, the preference of many consumers for well-accepted wood
products, the somewhat different appearance of Trex, the greater initial
expense of installing a Trex deck and the established relationships existing
between suppliers of wood decking products and contractors and homebuilders.
The Company's failure to achieve increased market acceptance of Trex would
have a material adverse effect on the Company's business, financial condition
and results of operations.     
 
Lack of Product Diversification
 
  All of the Company's net sales are derived from Trex. Although the Company
has developed new Trex products and new applications for Trex since 1992, and
intends to continue such development, the Company's product line is based
exclusively on the composite formula and manufacturing process for Trex Wood-
Polymer lumber. If the Company should experience any problems, real or
perceived, with product quality or acceptance of Trex, the Company's lack of
product diversification would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
Dependence on Single Manufacturing Facility
   
  Trex is currently produced solely in the Company's manufacturing facility in
Winchester, Virginia. Any interruption in the operations or decrease in the
production capacity of this facility, whether because of equipment failure,
natural disaster or otherwise, would limit the Company's ability to meet
existing and future customer demand for Trex and would have a material adverse
effect on the Company's business, financial condition and results of
operations. The Company has acquired the site for, and in January 1999 began
construction of, a second manufacturing facility, which will be located near
Reno, Nevada. The new facility is expected to begin production in the third
quarter of 1999, but construction and equipping of the facility is subject to
risks that could delay commencement of operations beyond that date. See "--
Ability to Increase Manufacturing Capacity."     
 
Reliance on Supply of Raw Materials
   
  Production of Trex requires substantial amounts of wood fiber and
polyethylene. The Company purchases wood fiber under contracts with a
relatively small number of suppliers primarily located within a 200-mile
radius of the Company's existing manufacturing facility in Winchester,
Virginia, and obtains polyethylene under purchase order arrangements with
suppliers of reclaimed grocery sacks     
 
                                       9

and stretch film throughout the United States. Four suppliers collectively
accounted for approximately 80% of the Company's 1998 wood fiber purchases.
For a description of the Company's supply agreements with such suppliers, see
"Business--Suppliers--Wood Fiber." The Company's ability to obtain adequate
polyethylene supplies depends on its success in developing new sources,
entering into long-term arrangements with suppliers and managing the
collection of supplies from geographically dispersed distribution centers. The
termination of the Company's relationships with suppliers of a significant
portion of its wood fiber or polyethylene requirements could subject the
Company to the risks that it would be unable to purchase sufficient quantities
of raw materials to meet its production requirements or would have to pay
higher prices for replacement supplies. Further, the Company generally obtains
its raw materials from existing suppliers at fixed prices that are established
annually. There can be no assurance that the Company will be successful in
maintaining such pricing policies to protect against fluctuations in raw
materials prices. The Company believes it will be able to obtain sufficient
additional wood and polyethylene supplies from its existing suppliers and new
supply sources to meet the increased requirements resulting from its recent
addition of two new production lines to its Winchester facility and its
establishment of a second manufacturing facility near Reno, Nevada, which the
Company expects to begin production in the third quarter of 1999. The Company
has not yet entered into supply agreements for the new facility. The
termination of significant sources of raw materials, the payment of higher
prices for raw materials or the failure to obtain sufficient additional raw
materials to meet planned increases in capacity could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "--Ability to Increase Manufacturing Capacity" and "Business--
Suppliers."     
 
Sensitivity to Economic Conditions
 
  The demand for decking products is sensitive to changes in the level of
activity in home improvements and, to a lesser extent, new home construction,
which are affected by such factors as consumer spending habits, employment,
interest rates and inflation. An economic downturn could reduce consumer
income available for spending on discretionary items such as decking, which
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Decking Market Overview."
 
Ability to Increase Manufacturing Capacity
   
  Currently, customer demand for Trex exceeds the Company's manufacturing
capacity. As part of its strategy to increase capacity, the Company recently
augmented the production capacity of its manufacturing facility in Winchester,
Virginia by adding one new production line in December 1998 and a second new
production line in January 1999. In addition, the Company has acquired the
site for, and in January 1999 began construction of, a second manufacturing
facility, which will be located near Reno, Nevada. The Company expects that
the new facility will begin production in the third quarter of 1999. See
"Business--Growth Strategies." In constructing and equipping the new facility,
the Company will be subject to the risks normally associated with the
development of manufacturing facilities, including risks relating to the
timely receipt of environmental and other regulatory approvals, the cost and
timely completion of construction (which may be affected by causes beyond the
Company's control, such as weather, labor conditions or material shortages)
and the availability of long-term borrowings to refinance on acceptable terms
short-term site acquisition and construction loans obtained by the Company.
Further, in the start-up and operation of the new facility and the two
additional production lines, the Company will be subject to the risks involved
in recruiting and training a factory workforce, installing and operating new
production equipment, purchasing raw materials, commencing manufacturing
operations and maintaining product quality. These risks could result in
substantial unanticipated delays or expense, which could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "--Dependence on Single Manufacturing Facility," "--Reliance
on Supply of Raw Materials" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."     
 
                                      10

Ability to Manage Growth
   
  The Company's recent growth has placed significant demands on its management
and other resources. The Company's net sales increased to $46.8 million in
1998 from $34.1 million in 1997 and $23.8 million in 1996. The number of
dealer outlets selling Trex has increased from approximately 1,200 at December
31, 1996 to approximately 2,000 at December 31, 1998, and further significant
increases are expected in the future. The Company also plans to support its
geographic expansion by opening a second manufacturing facility, which will be
located near Reno, Nevada. To manage its growth effectively, the Company will
need to continue to develop and improve its operational, financial, accounting
and other internal systems. In addition, the Company's future success will
depend in large part upon its ability to recruit, train, motivate and retain
senior managers and other employees and to maintain product quality. If the
Company is unable to manage its growth effectively, such inability could have
a material adverse effect on the quality of the Company's products and its
business, financial condition and results of operations.     
 
Seasonality and Fluctuations in Quarterly Operating Results
 
  The Company's net sales and income from operations historically have varied
from quarter to quarter. Such variations are principally attributable to
seasonal trends in the demand for Trex. The Company experiences lower net
sales levels during the fourth quarter, in which holidays and adverse weather
conditions in certain regions usually reduce the level of home improvement and
new construction activity. Income from operations and net income tend to be
lower in quarters with lower sales due to a lower gross margin which is not
offset by a corresponding reduction in selling, general and administrative
expenses, in part because the Company continues to make advertising
expenditures throughout the year. As a result of these factors, the Company
believes period-to-period comparisons of its net sales and other operating
results should not be relied upon as indicators of future performance, and the
results of any quarterly period may not be indicative of results to be
expected for a full year. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Seasonality."
 
Significant Capital Requirements
   
  Expansion of the Company's production capacity will require significant
capital expenditures. The Company currently estimates that its aggregate
capital requirements in 1999 and 2000 will total approximately $23.8 million,
of which approximately $20.3 million is expected to be incurred in 1999 and
approximately $3.5 million in 2000. Capital expenditures will be used
primarily for the construction and equipping of the Company's new
manufacturing facility, which will be located near Reno, Nevada and which the
Company expects to begin production in the third quarter of 1999. The Company
believes that the net proceeds of the Offering, together with cash on hand,
cash flow from operations and borrowings expected to be available under the
Company's current revolving credit agreement and construction loan for the new
facility, will provide sufficient funds to enable the Company to expand its
business as currently planned for at least the next 12 months. The actual
amount and timing of the Company's future capital requirements may differ
materially from the Company's estimates depending on the demand for Trex and
as a result of new market developments and opportunities. The Company may
determine that it is necessary or desirable to obtain financing for such
requirements through bank borrowings or the issuance of debt or equity
securities. Debt financing would increase the leverage of the Company, while
equity financing may dilute the ownership of the Company's stockholders. There
can be no assurance as to whether, or as to the terms on which, the Company
will be able to obtain such financing. Any failure by the Company to generate
sufficient funds from operations or equity or debt financings to meet its
capital requirements could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."     
 
                                      11
<PAGE>
 
Dependence on Significant Distributors
   
  The Company's aggregate net sales to its five largest distributors accounted
for approximately 74% of the Company's net sales in 1998. The Company's
contracts with these distributors are terminable by the distributors upon
notice at any time during the contract term. Although the Company believes it
would be able to replace any current distributor, a contract termination or
significant decrease or interruption in business from any of its five largest
distributors or any other significant distributor could cause a short-term
disruption of the Company's operations. Such a disruption could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Distribution."     
 
Dependence on Key Personnel
 
  The Company's success will depend in large part upon the continued services
of a small number of key management employees, including Anthony J. Cavanna,
Andrew U. Ferrari, Robert G. Matheny and Roger A. Wittenberg. None of such
employees is party to an employment agreement with the Company. The loss of
the services of one or more of the Company's key employees could have a
material adverse effect on the Company. In addition, if one or more of the
Company's key employees resigns from the Company to join a competitor or to
form a competing company, the loss of such employees and any resulting loss of
existing or potential customers to such competitor could have a material
adverse effect on the Company's business, financial condition and results of
operations. In the event of the loss of any such personnel, there can be no
assurance that the Company would be able to prevent the unauthorized
disclosure or use of its technical knowledge, practices or procedures by such
personnel. Although the Company's key employees are parties to agreements
containing confidentiality covenants, there can be no assurance that courts
will enforce such covenants as written or that the agreements will deter
conduct prohibited by such covenants. See "Management."
 
Competition
   
  The residential and commercial decking market in which the Company
principally operates is highly competitive. As a wood/plastic composite
product, Trex competes with wood, other wood/plastic composites and 100%
plastic lumber for use as decking. The primary competition for Trex is wood
decking, which accounted for approximately 97% of 1997 decking sales (measured
by board feet of lumber). The conventional lumber suppliers with which the
Company competes in many cases have established ties to the building and
construction industry and have well-accepted products. Many of the Company's
competitors in the decking market that sell wood products have significantly
greater financial, technical and marketing resources than the Company. The
Company's ability to compete depends, in part, upon a number of factors
outside its control, including the ability of its competitors to develop new
non-wood decking alternatives which are competitive with Trex. Trex is the
only non-wood decking alternative to receive a product building code listing
from the NES or any of its three regional members. A product building code
listing covers all uses of a product meeting the specified design criteria.
The Company is aware of one manufacturer of wood/plastic composite products
that has publicly announced it has applied for a regional application listing
for its products and of at least four manufacturers that have applied for
regional application listings of their 100% plastic lumber products. An
application listing covers specific uses of the listed products. There can be
no assurance that one or more of the Company's competitors will not receive a
listing for their non-wood decking alternative products in the immediate
future. Any product receiving such a listing could be more competitive with
Trex. The Company's failure to compete successfully with its competitors would
have a material adverse effect on the Company's business, operating results
and financial condition. See "Business--Competition."     
 
Impact of Government Regulation
 
  The Company is subject to federal, state and local environmental,
occupational health and safety, and other laws and regulations. The
environmental laws and regulations applicable to the Company's
 
                                      12
<PAGE>
 
   
operations establish air quality standards for emissions from the Company's
manufacturing operations, govern the disposal of solid waste, and regulate
waste water and storm water discharge. The Company believes that it currently
complies in all material respects with such environmental laws and
regulations. As is the case with manufacturers in general, the Company may be
held liable for response costs and damages to natural resources if a release
or threat of release of hazardous materials occurs on or from the Company's
properties or any associated offsite disposal location, or if contamination
from prior activities is discovered at any properties owned or operated by the
Company. Such a liability could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business--Government Regulation."     
 
Year 2000 Compliance
   
  The Company and third parties with which the Company does business rely on
numerous computer programs in their day-to-day operations. The Company has
undertaken a program to address the Year 2000 problem as it relates to the
Company's internal computer systems and the third-party computer systems with
which the Company interacts, including the systems of its major suppliers and
customers. The Company expects to continue to incur internal staff costs and
other expenses, which may be significant and will be expensed as incurred, to
address these issues. In addition, the appropriate course of action may
include replacement or an upgrade of certain systems or equipment at a
substantial cost to the Company. There can be no assurance that the Year 2000
issues will be resolved in 1999. If not resolved, such issues could have a
material adverse impact on the Company's business, operating results and
financial condition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Year 2000 Compliance."     
 
Influence by Principal Stockholders
   
  Upon completion of the Offering, the Company's four management stockholders
will beneficially own approximately 68.3% of the Common Stock (65.9% if the
Over-Allotment Option is exercised in full). As a result, such stockholders
collectively will be able to exercise control over the Company's business and
affairs by virtue of their voting power with respect to the election of
directors and actions requiring stockholder approval. See "Management,"
"Principal and Selling Stockholders" and "Description of Capital Stock."     
 
Intellectual Property
 
  The Company's success depends, in part, upon its intellectual property
rights. The Company relies upon a combination of trade secret, nondisclosure
and other contractual arrangements, and copyright and trademark laws to
protect its proprietary rights. The Company also has obtained patent
protection for certain of its production processes. The Company enters into
confidentiality agreements with its employees and limits access to and
distribution of its proprietary information. There can be no assurance that
the steps taken by the Company in this respect will be adequate to deter
misappropriation of its proprietary information or that the Company will be
able to detect unauthorized use and take appropriate steps to enforce its
intellectual property rights. See "Business--Intellectual Property."
 
Certain Anti-Takeover Provisions
   
  Certain provisions of the Company's Certificate of Incorporation (the
"Certificate of Incorporation") and Bylaws (the "Bylaws") and the General
Corporation Law of the State of Delaware (the "Delaware General Corporation
Law") could have anti-takeover effects even if a change of control of the
Company would be beneficial to the interests of the Company's stockholders.
These provisions include a requirement that the Board of Directors be divided
into three classes, with approximately one-third of the directors to be
elected each year. This classification of directors makes it more difficult
for an acquiror or for other stockholders to change the composition of the
Board of Directors. In addition, the Certificate of Incorporation authorizes
the Board of Directors to provide for the issuance of up to 3,000,000 shares
of preferred stock of the Company,     
 
                                      13
<PAGE>
 
   
in one or more series, which the Board of Directors could issue without
stockholder approval and upon such terms and conditions, and having such
rights, privileges and preferences, as the Board of Directors may determine.
The ability to issue preferred stock could have the effect of discouraging
unsolicited acquisition proposals or making it more difficult for a third
party to gain control of the Company, or otherwise could adversely affect the
market price of the Common Stock. Further, the Company is subject to Section
203 of the Delaware General Corporation Law, which prohibits it from engaging
in certain business combinations with stockholders that beneficially own 15%
or more of the Company's voting stock, or with the affiliates of such
stockholders, unless the Company's directors or stockholders approve the
business combination in the prescribed manner. See "Description of Capital
Stock--Anti-Takeover Effect of Certain Charter and Bylaw Provisions" and "--
Section 203 of the Delaware General Corporation Law."     
 
No Prior Public Market; Possible Volatility of Share Price
   
  Prior to the Offering, there has been no market for the Common Stock.
Although the Common Stock has been approved for listing on the New York Stock
Exchange subject to notice of issuance, there is no assurance that an active
trading market for the Shares will develop or be sustained after the Offering.
       
  There can be no assurance that the market price of the Shares will not
decline below the initial public offering price. The initial public offering
price will be determined by negotiations among the Company, the Selling
Stockholders and the representative of the Underwriters and may not be
indicative of future market prices. See "Underwriting" for information
relating to the factors to be considered in determining the initial public
offering price. In recent years, stock markets have experienced extreme price
and volume fluctuations. The trading price of the Shares could be subject to
wide fluctuations in response to quarterly variations in operating results,
changes in earnings estimates by analysts, announcements of new contracts or
product offerings by the Company or its competitors, general economic or stock
market conditions and other events or factors.     
 
Dilution to New Investors
   
  The initial public offering price per Share is substantially higher than the
Company's net tangible book value per share of Common Stock. Purchasers of
Shares in the Offering will experience immediate dilution of $11.56 in the pro
forma net tangible book value per Share and may experience further dilution
upon the exercise of future options to purchase shares of Common Stock. See
"Dilution."     
 
No Dividends
 
  The Company does not anticipate paying any cash dividends on the Common
Stock in the foreseeable future. The Company's revolving credit facility
contains provisions restricting the Company's ability to pay cash dividends on
the Common Stock. See "Dividend Policy."
   
Benefits of Offering to Selling Stockholders and Other Current Investors     
   
  Approximately $27.8 million of the net proceeds of the Offering will be used
to repay indebtedness of the Company to Connecticut General Life Insurance
Company, Connecticut General Life Insurance Company on behalf of one or more
separate accounts, Life Insurance Company of North America and Lincoln
National Life Insurance Company, all of which own equity interests in the
Company and one or more of which may be deemed affiliates of the Company prior
to the Offering (collectively the "Institutional Investors"). The Company
incurred such indebtedness in connection with the Acquisition. In addition,
the Company will use approximately $3.1 million of the net proceeds of the
Offering to purchase Mobil's preferred equity interest in the Company issued
in connection with the Acquisition.     
   
  The Selling Stockholders, all of which are Institutional Investors, will
receive substantial proceeds from the Offering and certain other benefits. The
Offering will establish a public market for the     
 
                                      14
<PAGE>
 
   
Common Stock and provide increased liquidity to the Selling Stockholders for
the shares of Common Stock they will own after the Offering. After deduction
of estimated underwriting discounts and commissions, the aggregate net
proceeds of the Offering to be received by the Selling Stockholders will total
approximately $1.3 million. See "Use of Proceeds," "Principal and Selling
Stockholders" and "Certain Transactions."     
   
  As part of the Reorganization, the Company will make the LLC Distribution of
approximately $9.3 million to its four management members and to the
Institutional Investors. A portion of the net proceeds of the Offering will be
used to pay approximately $6.9 million of the LLC Distribution. The amount of
the LLC Distribution and the amount of the net proceeds of the Offering to be
applied in respect thereof are subject to adjustment based on the Company's
actual taxable income from January 1, 1999 through the date of the LLC
Distribution. See "Use of Proceeds," "Principal and Selling Stockholders" and
"Certain Transactions."     
 
Shares Eligible for Future Sale; Registration Rights
   
  Future sales of a substantial number of shares of Common Stock in the public
market, or the perception that such sales could occur, could adversely affect
the prevailing market price of the Common Stock and could make it more
difficult for the Company to raise funds through a public offering of its
equity securities. Upon completion of the Offering, there will be 13,500,000
shares of Common Stock outstanding, including the 3,353,000 Shares sold in the
Offering. The 3,353,000 Shares offered hereby, other than up to 162,500 shares
reserved for issuance to directors and employees of the Company and certain
other persons (the "Reserved Shares"), will be freely tradable upon completion
of the Offering without restriction under the Securities Act of 1933, as
amended (the "Securities Act"), by persons other than "affiliates" of the
Company as defined in Rule 144 under the Securities Act. The remaining
10,147,000 shares of Common Stock will be deemed "Restricted Securities"
within the meaning of Rule 144 and, as such, may not be sold in the absence of
registration under the Securities Act or an exemption therefrom, including the
exemption afforded by Rule 144. In connection with the Offering, the Company,
all stockholders of the Company prior to the Offering and the holders of
Reserved Shares have entered into "lock-up" agreements with the Underwriters.
The Company and such stockholders have agreed that they will not offer, sell,
contract to sell, issue or otherwise dispose of any shares of Common Stock or
any securities of the Company which are substantially similar to the Common
Stock or which are convertible into or exchangeable or exercisable for Common
Stock or securities substantially similar to the Common Stock for a period of
180 days after the closing of the Offering without the prior written consent
of Schroder & Co. Inc., which it may grant in whole or in part without a
public announcement. The foregoing restrictions will not apply to the issuance
of options to purchase Common Stock pursuant to the Stock Incentive Plan or
the Outside Director Plan, to transfers of Common Stock to the Company or to
certain transfers of Common Stock to family trusts or by gift, will or
intestate succession. As a condition to any such transfer to a family trust or
transfer by gift, will or intestate succession, the transferee (or trustee or
legal guardian on the transferee's behalf) will be required to execute and
deliver a lock-up agreement containing the terms described in this paragraph.
Upon expiration of the lock-up period, the Reserved Shares will be freely
tradable by persons other than affiliates of the Company and up to 10,147,000
shares of Common Stock will be eligible for sale under Rule 144. See "Shares
Eligible for Future Sale."     
 
  The Company has granted "demand" and "piggyback" registration rights with
respect to the Common Stock held by the Institutional Investors. The
Institutional Investors are entitled to require the Company to register the
sale of their shares under the Securities Act on up to two occasions. In
addition, if the Company proposes to register the Common Stock under the
Securities Act (other than pursuant to a registration statement on Form S-4 or
Form S-8), whether or not for its own account, the Institutional Investors are
entitled to require the Company, subject to certain conditions, to include all
or a portion of their shares in such registration. The foregoing registration
rights are subject to
 
                                      15
<PAGE>
 
   
certain notice requirements, timing restrictions and volume limitations which
may be imposed by the underwriters of an offering. The Company is required to
bear the expenses of all such registrations except for underwriting discounts
and commissions. Following the consummation of the Offering, 922,000 shares of
Common Stock, or 6.8% of total number of outstanding shares of Common Stock,
will be entitled to the benefits of such registration rights. See "Certain
Transactions--Acquisition Transactions."     
 
                                      16
<PAGE>
 
                                USE OF PROCEEDS
   
  The net proceeds to the Company from the Offering after deducting
underwriting discounts and commissions and after expenses of the Offering are
expected to be $41.6 million ($48.1 million if the Over-Allotment Option is
exercised in full). The Company will not receive any of the net proceeds from
the sale of Shares by the Selling Stockholders.     
   
  The Company will use approximately $27.8 million of the net proceeds of the
Offering to repay $26.3 million principal amount of indebtedness and a related
prepayment premium of approximately $1.5 million. Such indebtedness, which was
incurred in connection with the Acquisition, consists of (i) $21.3 million
principal amount of senior notes, which accrue interest at an annual rate of
10% and mature on August 30, 2003 (the "Senior Notes"), and (ii) $5.0 million
principal amount of subordinated notes, which accrue interest at an annual
rate of 12% and mature on August 30, 2004 (the "Subordinated Notes"). The
Senior Notes and the Subordinated Notes are held by the Institutional
Investors, one or more of which may be deemed affiliates of the Company prior
to the Offering. The Company also will use approximately $3.1 million of the
net proceeds of the Offering to purchase Mobil's preferred equity interest in
the Company issued in connection with the Acquisition and in payment of
accrued and unpaid dividends thereon. See "Certain Transactions--Acquisition
Transactions." The Company will pay approximately $6.9 million of the net
proceeds of the Offering to fund a portion of the LLC Distribution to its four
management members and to the Institutional Investors. The estimated LLC
Distribution as of December 31, 1998 is $5.6 million. Such amount will be
increased by the amount of any taxable income realized by the Company from
January 1, 1999 through the date of the LLC Distribution. The amount of the
net proceeds of the Offering to be applied in respect of the LLC Distribution,
which is estimated to be approximately $9.3 million as of the expected payment
date, is subject to adjustment based on the actual amount of the LLC
Distribution. See "Certain Transactions--Reorganization."     
   
  The Company intends to use up to all of the remaining net proceeds of the
Offering of approximately $3.8 million to equip the Company's second
manufacturing facility. Any proceeds not used for this purpose will be applied
to working capital and other general corporate purposes. The Company estimates
that the total cost of the site acquisition, construction and equipping of its
second manufacturing facility will be approximately $19.6 million.     
 
  Pending the foregoing uses, the net proceeds of the Offering will be
invested in short-term, interest-bearing, investment grade securities.
 
                                DIVIDEND POLICY
   
  The Company intends to retain future earnings, if any, to finance the
development and expansion of its business and, therefore, does not anticipate
paying any cash dividends on the Common Stock in the foreseeable future. The
payment of dividends is within the discretion of the Board of Directors and
will be dependent upon, among other factors, the Company's results of
operations, financial condition and capital requirements, restrictions imposed
by the Company's financing agreements and legal requirements. Under the terms
of its revolving credit facility, the Company may pay cash dividends only if,
after payment of such dividends, the ratio of its total consolidated debt to
its total consolidated capitalization does not exceed 50%.     
   
  Prior to the Reorganization, the Company has been treated as a partnership
for federal and state income tax purposes. The Company made distributions to
its members of $1.6 million in 1997 and $2.3 million in 1998 to satisfy their
allocated portion of the Company's taxable income. As part of the
Reorganization, the Company will make the LLC Distribution of approximately
$9.3 million to certain of its members. The amount of the LLC Distribution is
subject to adjustment based on the Company's actual taxable income from
January 1, 1999 through the date of the LLC Distribution. See "Certain
Transactions--Reorganization."

  The following table sets forth, as of December 31, 1998, (i) the actual
capitalization of the Company, (ii) the pro forma capitalization of the
Company after giving effect to the Reorganization and (iii) the pro forma

                                   DILUTION
   
  At December 31, 1998, the deficit in pro forma net tangible book value of
the Common Stock, after giving effect to the Reorganization, was $(4.9)
million, or approximately $(0.48) per share outstanding. As of December 31,
1998, the pro forma as adjusted net tangible book value of the Common Stock,
after giving effect to the Reorganization and the consummation of the Offering
and the application of the net proceeds therefrom, was $33.0 million, or
approximately $2.44 per share outstanding. This represents an immediate
increase in pro forma net tangible book value of $2.92 per share to existing
stockholders and an immediate dilution in net tangible book value of $11.56
per share to new investors purchasing Shares in the Offering. The net tangible
book value per share of Common Stock represents the amount of the Company's
tangible assets less its liabilities divided by the number of shares of Common
Stock outstanding. The following table illustrates this dilution in net
tangible book value per share to new investors at December 31, 1998:

(1) On August 29, 1996, the Company acquired substantially all of the assets
    and assumed certain of the liabilities of the Predecessor for a purchase
    price of approximately $29.5 million. See "Certain Transactions--
    Acquisition Transactions."
   
(2) The pro forma statement of operations data do not include adjustments to
    reflect recognition of a one-time non-cash tax charge of approximately $1.4
    million for the year ended December 31, 1998 with respect to a net deferred
    tax liability related to the Company's conversion in the Reorganization to
    a C corporation. Such data give effect to the conversion as if it had
    occurred on January 1, 1998. The pro forma income tax provision is
    calculated at a combined federal and state income tax rate of 40%. See
    "Management's Discussion and Analysis of Financial Condition and Results of
    Operations--Overview" and "Certain Transactions--Reorganization."
    Historical interest income has been eliminated to reflect application of
    cash balances to fund a portion of the LLC Distribution. The pro forma cash
    flow data reflect $1.0 million of the $5.6 million LLC Distribution. The
    remaining $4.6 million of the LLC Distribution will be paid from the net
    proceeds of the Offering.     
   
(3) The pro forma, as adjusted, statement of operations data have been computed
    by eliminating interest expense of $2.8 million related to debt that will
    be repaid with a portion of the net proceeds of the Offering. The pro
    forma, as adjusted, statement of operations data do not include adjustments
    to (i) record an extraordinary loss, net of taxes, of $1.1 million for the
    year ended December 31, 1998 related to the extinguishment of such debt or
    (ii) reflect recognition of a one-time non-cash tax charge of approximately
    $1.4 million for the year ended December 31, 1998 with respect to a net
    deferred tax liability related to the Company's conversion in the
    Reorganization to a C corporation. Such data give effect to the conversion
    as if it had occurred on January 1, 1998. The pro forma, as adjusted,
    income tax provision is calculated at a combined federal and state income
    tax rate of 40%. See "Management's Discussion and Analysis of Financial

   of the LLC Distribution.     
   
(4) For the periods shown, the Predecessor was included in the consolidated
    tax return of its parent and, accordingly, no tax provision was provided.
    For all periods since inception, the Company elected to be treated as a
    partnership for federal and state income tax purposes. As a result, the
    Company's income has been taxed directly to the Company's members, rather
    than to the Company.

(6) Pro forma and pro forma, as adjusted, net income and net income per share
    for the year ended December 31, 1998 do not include adjustments to record
    deferred income tax expense of $1.4 million as a result of the Company's

(8) Consists of income (loss) from operations plus depreciation and
    amortization. EBITDA is presented because it is a commonly used measure of
    performance by the financial community. Although management believes
    EBITDA is a useful measure of the Company's performance, EBITDA should not
    be considered an alternative to net income (loss) as a measure of
    operating performance or to cash provided by (used for) operating
    activities as a measure of liquidity. In addition, this measure of EBITDA
    may not be comparable to similarly titled measures reported by other

    LLC Distribution adjustment is calculated as if the LLC Distribution had
    been made on December 31, 1998 and is based in part on the estimated
    amount of previously recognized and undistributed income of the Company
    through such date, while the $9.3 million LLC Distribution amount
    appearing elsewhere in this Prospectus also reflects the then estimated
    additional results of operations of the Company from January 1, 1999
    through the estimated date of the LLC Distribution. The $5.6 million
    amount as of December 31, 1998 will be increased by the amount of any

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
Overview
   
  The Company is the nation's largest manufacturer of non-wood decking
alternative products, which are marketed under the brand name Trex. Trex Wood-
Polymer lumber is a wood/plastic composite that offers an attractive
appearance and the workability of wood without wood's on-going maintenance
requirements and functional disadvantages. Trex is manufactured in a
proprietary process that combines waste wood fibers and reclaimed polyethylene
and is used primarily for decking. Trex also has non-decking product
applications, including industrial block flooring, applications for parks and
recreational areas, floating and fixed docks and other marine applications,
and landscape edging.     
   
  The primary market for Trex is residential and commercial decking, which
accounted for approximately 85% of the Company's 1998 net sales. The Company
seeks to achieve sales growth in the decking market by converting demand for
wood decking products into demand for Trex. Wood decking accounted for
approximately 97% of 1997 decking sales (measured by board feet of lumber).
The Company's strategy to increase market acceptance of Trex is to develop and
promote the Trex brand name as a premium decking product and to emphasize the
advantages of Trex over wood decking products. The Company has invested over
$10 million during the last three years to develop Trex as a recognized brand
name. The Company focuses on the contractor-installed market segment, since
this segment represents 70% of the decking market (measured by board feet of
lumber) and since contractors generally build larger and more elaborate
residential decks than decks built by homeowners in the "do-it-yourself"
market segment.     
   
  The Company has developed an extensive distribution network which
complements its branding strategy and its focus on the contractor-installed
market segment. At December 31, 1998, the Company sold Trex through
approximately 55 wholesale distribution locations. At the same date, the
Company's distributors marketed Trex to approximately 2,000 dealer outlets,
which directly service contractors and consumers.     
   
  Net sales consists of sales net of returns and discounts. The Company has
experienced net sales growth each year since it began operations in 1992. The
increase in net sales is primarily attributable to the growth in sales volume,
which increased from 16.2 million pounds of finished product in 1993, the
first full year of operations, to 151.6 million pounds in 1998. The Company's
branding and product differentiation strategy enables the Company both to
command premium prices and to maintain price stability for Trex. Prices for
Trex over the last three years have increased at a compounded annual growth
rate of approximately 4%.     
 
  From time to time since 1992, customer demand for Trex has exceeded the
Company's manufacturing capacity. The constraints on the Company's capacity in
these periods have limited the rate of the Company's net sales growth.
   
  The Company's cost of sales consists of raw material costs, direct labor
costs and manufacturing costs, including depreciation. In the last three
years, the cost of raw materials increased an average of approximately 5.0%
annually. Almost all of the increases were attributable to higher costs of
polyethylene. Although cost of sales has increased with the growth in net
sales, cost of sales as a percentage of net sales decreased in 1998 from the
level in 1997. During this period, productivity gains from the Company's
investment in manufacturing process improvements and the addition of
production lines outweighed increases in raw material and direct labor costs.
Production line rates, which are measured in pounds of finished product per
production hour, have increased over 200%     
 
                                      23
<PAGE>
 
   
since 1992, and the number of production lines has increased from one line in
1992 to seven lines in 1998. The Company expects that cost of sales as a
percentage of net sales will decrease in the first half of 1999 because the
Company has augmented its manufacturing capacity through the addition of one
new production line to its Winchester facility in December 1998 and a second
new production line in January 1999.     
   
  The principal component of selling, general and administrative expenses is
sales and marketing costs, which have increased significantly as the Company
has sought to build brand awareness of Trex in the decking market. Sales and
marketing costs consist primarily of salaries, commissions and benefits paid
to sales and marketing personnel, advertising expenses and other promotional
costs. General and administrative expenses include salaries and benefits of
personnel engaged in research and development, procurement, accounting and
other business functions and office occupancy costs attributable to such
functions, as well as amortization expense. As a percentage of net sales,
selling, general and administrative expenses have varied from quarter to
quarter, especially when the Company has determined to build inventory
selectively and to continue expenditures for advertising.     
   
  In connection with the Acquisition, the Company incurred indebtedness of
$29.3 million, of which $26.3 million was outstanding at December 31, 1998,
and recorded $11.3 million for goodwill and organizational cost, substantially
increasing its interest and amortization expense. The Company will repay its
Acquisition-related indebtedness with a portion of the net proceeds of the
Offering. See "Use of Proceeds." In the quarter in which the Offering is
consummated, as a result of repayment of such indebtedness, the Company will
recognize an extraordinary cash charge against income of $1.5 million on a
pre-tax basis for early extinguishment of debt and an extraordinary $0.2
million non-cash charge against income for the write-off of unamortized debt
discount. The Company is amortizing its goodwill over a 15-year period in an
amount of approximately $0.7 million per year and organizational cost over a
five-year period in an amount of approximately $0.1 million per year.     
   
  The Company did not record an income tax provision for any period through
the date of the Offering. Prior to the Acquisition, the Company was included
in the consolidated tax return of its parent company. Since the Acquisition,
the Company has elected to be treated as a partnership for federal and state
income tax purposes, and the Company's income has been taxed directly to the
Company's members, rather than to the Company. Upon consummation of the
Reorganization, the Company will become subject to income tax as a corporation
taxed in accordance with Subchapter C of the Internal Revenue Code. In the
quarter in which the Offering is consummated, as a result of the Company's
conversion to C corporation status, the Company will recognize a $2.4 million
non-cash charge against income for income tax expense. The effect of this
charge will be to increase substantially the Company's effective tax rate for
the quarter in which the Reorganization is consummated. The increased
effective tax rate will be recognized only in such quarter and, accordingly,
the Company believes that its effective tax rate for subsequent periods should
not exceed approximately 40%.

(1)  Reflects the sum of the selected statement of operations data for the
     Predecessor during the period January 1, 1996 to August 28, 1996 and for
     the Company during the period August 29, 1996 to December 31, 1996.
 
(2)  The Company did not record an income tax provision for any period through
     the date of the Offering. The Predecessor was included in the
     consolidated tax return of its parent company and, accordingly, no tax
     provision was provided. The Company has elected to be treated as a
     partnership for federal and state income tax purposes for all periods
     since inception. As a result, the income of the Company has been taxed
     for such purposes directly to the Company's members, rather than to the
     Company.
   
1998 Compared to 1997     
   
  Net Sales. Net sales increased 37.2% to $46.8 million in 1998 from $34.1
million in 1997. The increase in net sales was attributable to the growth in
sales volume, which increased to 151.6 million pounds of finished product in
1998 from 113.9 million pounds in 1997, and, to a lesser extent, to a price
increase of approximately 3.1%. Production line rate increases and the
addition of a sixth production line in the second quarter of 1998
significantly increased the Company's production capacity in 1998. To
stimulate demand for Trex, the Company increased expenditures on network and
cable television advertising and instituted incentive sales programs in 1998.
Increased sales of a railing product and a Trex color introduced in 1997 also
contributed to the higher sales volume. The Company substantially increased
the number of dealer outlets, from approximately 1,500 at December 31, 1997 to
approximately 2,000 at December 31, 1998.     
   
  Cost of Sales. Cost of sales increased 36.9% to $23.0 million in 1998 from
$16.8 million in 1997. All components of cost of sales increased to support
the higher level of sales activity. Cost of sales as a percentage of net sales
decreased to 49.0% in 1998 from 49.1% in 1997. The decline principally
reflected operating efficiencies from improved production line rates.     
   
  Gross Profit. Gross profit increased 37.4% to $23.9 million in 1998 from
$17.4 million in 1997, reflecting the higher sales volume in 1998. Gross
profit as a percentage of net sales increased to 51.0% in 1998 from 50.9% in
1997. The contribution to gross profit of greater operating efficiencies more
than offset the effects of discounts offered by the Company to distributors in
1998 as part of its sales incentive programs.     
   
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 43.3% to $12.9 million in 1998 from $9.0
million in 1997. The increase was primarily attributable to higher sales and
marketing expenses, which increased 47.1% to $7.5 million in 1998     
 
                                      25
<PAGE>
 
   
from $5.1 million in 1997. The largest component of the increase was
advertising and promotion costs, which increased 50.6% as the Company expanded
promotion of the Trex brand on network and cable television. The Company also
incurred higher personnel costs through additions to its sales and marketing
staff. The increase in corporate personnel and the upgrading of accounting and
other systems to support growth contributed to a 61.0% increase in general and
administrative expenses. Selling, general and administrative expenses as a
percentage of net sales increased to 27.5% in 1998 from 26.3% in 1997.     
   
  Interest Expense. Net interest expense decreased 10.7% to $2.5 million in
1998 from $2.8 million in 1997. The decrease primarily resulted from lower
average borrowings attributable to the Company's prepayment of $3.0 million
principal amount of Senior Notes in the second quarter of 1997.     
 
1997 Compared to 1996
   
  Net Sales. Net sales increased 43.3% to $34.1 million in 1997 from $23.8
million in the period January 1, 1996 to August 28, 1996 and the period August
29, 1996 to December 31, 1996 (such periods together, "1996"). The increase in
net sales was attributable to the growth in sales volume, which increased to
113.9 million pounds of finished product in 1997 from 81.4 million pounds in
1996, and, to a lesser extent, to a price increase of approximately 2.9%. The
Company's production capacity in 1997 was significantly augmented by a fifth
production line added in the third quarter of 1996. The Company used the
additional capacity to build up inventories in late 1996 for sale in 1997. The
introduction of a new railing product and a new Trex color also contributed to
the higher sales volume in 1997. The Company significantly expanded its
distribution network by increasing the number of dealer outlets from
approximately 1,200 at December 31, 1996 to approximately 1,500 at December
31, 1997.     
 
  Cost of Sales. Cost of sales increased 32.3% to $16.8 million in 1997 from
$12.7 million in 1996. Raw materials purchases, direct labor costs and
manufacturing costs all increased to support the higher sales volume in 1997.
Cost of sales as a percentage of net sales declined to 49.1% in 1997 from
53.3% in 1996. The decline was primarily attributable to improved production
line rates resulting from the efforts of an engineering team assigned in 1996
to focus on productivity improvements.
   
  Gross Profit. Gross profit increased 55.9% to $17.3 million in 1997 from
$11.1 million in 1996, reflecting the higher sales volume in 1997. Gross
profit as a percentage of net sales increased to 50.9% in 1997 from 46.7% in
1996. The increase was primarily attributable to operating efficiencies
resulting from improved production line rates.     
   
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 11.1% to $9.0 million in 1997 from $8.1
million in 1996. The increase resulted principally from higher sales and
marketing expenses, which increased 21.4% to $5.1 million in 1997 from
$4.2 million in 1996. An increase of 14.8% in advertising costs over 1997 and
the addition of new sales and marketing personnel contributed to the higher
sales and marketing expenses. The increased general and administrative
expenses in 1997 reflected an expense of $0.8 million from amortization of
goodwill and organizational costs incurred in connection with the Acquisition.
Selling, general and administrative expenses as a percentage of net sales
decreased to 26.3% in 1997 from 33.9% in 1996.     
   
  Interest Expense. Net interest expense increased to $2.8 million in 1997
from $0.9 million in 1996. The increase reflected a full year of interest
expense on indebtedness incurred in connection with the Acquisition. See
"Certain Transactions--Acquisition Transactions."     
 
Seasonality
 
  The Company's net sales and income from operations historically have varied
from quarter to quarter. Such variations are principally attributable to
seasonal trends in the demand for Trex. The
 
                                      26
<PAGE>
 
Company experiences lower net sales levels during the fourth quarter, in which
holidays and adverse weather conditions in certain regions usually reduce the
level of home improvement and new construction activity. Income from
operations and net income tend to be lower in quarters with lower sales due to
a lower gross margin which is not offset by a corresponding reduction in
selling, general and administrative expenses, in part because the Company
continues to make advertising expenditures throughout the year. The Company
utilizes a variety of sales incentive programs with customers to reduce the
effects of seasonality.
 
Liquidity and Capital Resources
 
  The Company historically has financed its operations and growth primarily
with cash flow from operations, operating leases, normal trade credit terms
and borrowings under its revolving credit facility.
   
  The Company's cash flow from operating activities was $12.2 million in 1998,
$6.5 million in 1997 and $2.6 million in 1996. Higher sales volume accounted
for the significant increase in cash flows in 1998.     
   
  The Company's working capital generally averages between 12% and 18% of
annual net sales. The Company's working capital needs correlate closely with
the level of the Company's net sales. Consequently, the Company's short-term
borrowing requirements are affected by the seasonality of its business. The
Company currently maintains a $6.0 million revolving credit facility, which
accrues interest at a rate equal to LIBOR plus 200 basis points. As of
December 31, 1998, no borrowings were outstanding under the facility. The
facility expires in April 1999, but the Company expects it will be able to
renew the facility on substantially the same terms.     
   
  The Company financed its purchase of its Winchester, Virginia facility in
June 1998 with a ten-year term loan of $3.8 million. Pursuant to an interest
rate swap agreement, the Company pays interest on this loan at an annual rate
of 7.12%.     
   
  The Company financed its purchase of the Trex Technical Center in November
1998 in part with the proceeds of a ten-year term loan of $1.0 million.
Pursuant to an interest rate swap agreement, the Company pays interest on this
loan at an annual rate of 6.8%.     
   
  The Company financed its acquisition of the site for its second
manufacturing facility in December 1998 in part with a $2.1 million loan which
is payable in September 1999. The Company will finance construction of the
facility in part with proceeds of up to $4.6 million under a construction loan
which is payable in November 1999. The site acquisition and construction loans
accrue interest at an annual rate of 7.5%. The Company intends to refinance
both loans with long-term borrowings. The Company will use cash flow from
operations to fund a portion of the costs of constructing and equipping its
new manufacturing facility. It also intends to use a portion of the net
proceeds of the Offering to equip the new facility. See "Use of Proceeds" and
"Business--Manufacturing Process."     
          
  As of December 31, 1998, the Company's long-term indebtedness, including
current portion, was $33.1 million, with an overall weighted average interest
rate of 9.7%. Of such indebtedness, $26.3 million principal amount of the
Senior Notes and the Subordinated Notes will be repaid from the net proceeds
of the Offering. See "Use of Proceeds."     
   
  The Company's major market risk exposure is to changing interest rates. The
Company's policy is to manage interest rates through the use of a combination
of fixed and floating rate debt. The Company uses interest rate swap contracts
to manage its exposure to fluctuations in interest rates on its floating-rate
debt, substantially all of which is based on LIBOR. At December 31, 1998, the
Company had effectively capped its interest rate exposure at approximately 7%
on approximately $4.7 million of its floating rate debt through 2008. See Note
6 to the Financial Statements of Trex Company, LLC appearing elsewhere in this
Prospectus.     
 
 
                                      27
<PAGE>
 
   
  As part of the Reorganization, the Company will make the LLC Distribution of
approximately $9.3 million to certain of its members. A portion of the net
proceeds of the Offering will be used to pay approximately $6.9 million of the
LLC Distribution. The Company will fund the balance of the LLC Distribution
from available cash. The amount of the LLC Distribution and the amount of the
net proceeds of the Offering to be applied in respect thereof are subject to
adjustment based on the Company's actual taxable income from January 1, 1999
through the date of the LLC Distribution. See "Certain Transactions--
Reorganization."     
   
  Expansion of the Company's production capacity will require significant
capital expenditures. The Company currently estimates that its aggregate
capital requirements in 1999 and 2000 will total approximately $23.8 million,
of which approximately $20.3 million is expected to be incurred in 1999 and
approximately $3.5 million in 2000. Capital expenditures will be used
primarily for the construction and equipping of the Company's new
manufacturing facility, which will be located near Reno, Nevada and which the
Company expects to begin production in the third quarter of 1999. The Company
believes that the net proceeds of the Offering, together with cash on hand,
cash flow from operations and borrowings expected to be available under the
Company's current revolving credit facility and construction loan, will
provide sufficient funds to enable the Company to expand its business as
currently planned for at least the next 12 months. The actual amount and
timing of the Company's future capital requirements may differ materially from
the Company's estimate depending on the demand for Trex and new market
developments and opportunities. The Company may determine that it is necessary
or desirable to obtain financing for such requirements through bank borrowings
or the issuance of debt or equity securities. Debt financing would increase
the leverage of the Company, while equity financing may dilute the ownership
of the Company's stockholders. There can be no assurance as to whether, or as
to the terms on which, the Company will be able to obtain such financing.     
 
Year 2000 Compliance
 
  The Company's Program. The Company has undertaken a program to address the
Year 2000 issue with respect to the following: (i) the Company's information
technology and operating systems (including its billing, accounting and
financial reporting systems); (ii) the Company's non-information technology
systems (such as buildings, plant, equipment and other infrastructure systems
that may contain embedded microcontroller technology); (iii) certain systems
of the Company's major suppliers and material service providers (insofar as
such systems relate to the Company's business activities with such parties);
and (iv) the Company's major distributors (insofar as the Year 2000 issue
relates to the ability of such distributors to distribute Trex to the
Company's dealer outlets). As described below, the Company's Year 2000 program
involves (i) an assessment of the Year 2000 problems that may affect the
Company, (ii) the development of remedies to address the problems discovered
in the assessment phase, (iii) the testing of such remedies and (iv) the
preparation of contingency plans to deal with worst case scenarios.
   
  Assessment Phase. As part of the assessment phase of its program, the
Company will attempt to identify substantially all of the major components of
the systems described above. To determine the extent to which such systems are
vulnerable to the Year 2000 issue, the Company has completed an evaluation of
its internally developed software applications and expects to begin
remediation and testing activities for such applications in the first quarter
of 1999. In addition, in the fourth quarter of 1998, the Company completed its
distribution of letters to certain of its major suppliers and other material
service providers and to the Company's major distributors, requesting them to
provide the Company with detailed, written information concerning existing or
anticipated Year 2000 compliance by their systems insofar as the systems
relate to such parties' business activities with the Company. The Company is
currently processing the responses to those inquiries and re-soliciting
responses from those entities that have not yet responded.     
 
 
                                      28
<PAGE>
 
   
  Remediation and Testing Phase. Based upon the results of its assessment
efforts, the Company will undertake remediation and testing activities. The
Company intends to complete this phase by June 30, 1999. The activities
conducted during the remediation and testing phase are intended to address
potential Year 2000 problems in computer software used by the Company in its
information technology and non-information technology systems in an attempt to
demonstrate that this software will be made substantially Year 2000 compliant
on a timely basis. In this phase, the Company will first evaluate a program
application and, if a potential Year 2000 problem is identified, will take
steps to attempt to remediate the problem and individually test the
application to confirm that the remediating changes are effective and have not
adversely affected the functionality of that application. After the individual
applications and system components have undergone remediation and testing
phases, the Company will conduct integrated testing for the purpose of
demonstrating functional integrated systems operation.     
   
  Contingency Plans. The Company intends to develop contingency plans to
handle its most reasonably likely worst case Year 2000 scenarios, which it has
not yet identified fully. The Company intends to complete its determination of
such worst case scenarios after it has received and analyzed responses to
substantially all of the inquiries it has made of third parties and completed
its remediation and testing activities. The Company expects to complete its
contingency plans by August 31, 1999.     
   
  Costs Related to the Year 2000 Issue. To date, the Company has incurred
approximately $5,000 in costs for its Year 2000 program. Such costs do not
include internal staff costs, consisting principally of payroll costs,
incurred on Year 2000 matters, because the Company does not separately track
such costs. The Company currently estimates that it will incur additional
costs (excluding internal staff costs), which are not expected to exceed
approximately $50,000, to complete its Year 2000 compliance work. Such costs
will constitute approximately 40% of the Company's budgeted expenditures for
information technology. Actual costs may vary from the foregoing estimates
based on the Company's evaluation of responses to its third-party inquiries
and on the results of its remediation and testing activities. The Company
expects to fund its Year 2000 remediation costs out of the cash flows
generated by its operations. The Company has not deferred any of its
information technology projects to date as a result of the Year 2000 issue.
    
  Risks Related to the Year 2000 Issue. Although the Company's Year 2000
efforts are intended to minimize the adverse effects of the Year 2000 issue on
the Company's business and operations, the actual effects of the issue and the
success or failure of the Company's efforts described above cannot be known
until the year 2000. Failure by the Company and its major suppliers, other
material service providers and major distributors to address adequately their
respective Year 2000 issues in a timely manner (insofar as such issues relate
to the Company's business) could have a material adverse effect on the
Company's business, results of operations and financial condition.
 
Inflation
   
  Inflation did not have a material impact on the Company's operating results
in 1998, 1997 or 1996.

                                   BUSINESS
 
General
   
  The Company is the nation's largest manufacturer of non-wood decking
alternative products, which are marketed under the brand name Trex(R). Trex
Wood-Polymer(TM) lumber is a wood/plastic composite that offers an attractive
appearance and the workability of wood without wood's on-going maintenance
requirements and functional disadvantages. Trex is manufactured in a
proprietary process that combines waste wood fibers and reclaimed polyethylene
and is used primarily for residential and commercial decking. The Company
promotes Trex among consumers and contractors as a premium decking product.
Net sales of Trex increased from $0.6 million in 1992 to $46.8 million in
1998. Income from operations increased from a loss of $5.6 million in 1992 to
a profit of $11.0 million in 1998.     
   
  The Company seeks to achieve sales growth in the decking market by
converting demand for wood decking products into demand for Trex. The Company
intends to continue to develop and promote the Trex brand name as a premium
decking product and to focus on the contractor-installed market segment. This
segment represents approximately 70% of the decking market (measured by board
feet of lumber) and since contractors generally build larger, more elaborate
residential decks than decks built by homeowners in the "do-it-yourself"
market segment. The Company sells its products through approximately 55
wholesale distribution locations, which in turn sell Trex to approximately
2,000 dealer outlets across the United States.     
 
  The Company was formed in August 1996 in a buyout of the assets of Mobil's
Composite Products Division. Mobil established the Composite Products Division
in April 1992 after purchasing the technology and related assets used to
create Trex. The buyout was led by four senior Mobil executives with over 75
years of combined management experience.
 
Decking Market Overview
   
  The decking market is part of the substantial home improvement market.
Expenditures for residential improvements and repairs totaled approximately
$118 billion in 1997, according to the U.S. Department of Commerce, and the
home improvement market grew at a compounded annual growth rate of 3.7% for
the seven-year period ended December 31, 1997. The primary market for Trex is
residential decking and, to a lesser extent, commercial decking. Annual
factory sales in 1997 of residential decking and commercial decking totaled
approximately $1.7 billion (approximately 2.0 billion board feet of lumber)
and approximately $200 million (approximately 225 million board feet of
lumber), respectively. This market includes all decking products other than
posts, beams and columns used for a deck's substructure. For the seven-year
period ended December 31, 1997, factory sales of all residential decking
increased at a compounded annual growth rate of approximately 8%. In recent
years, factory sales of non-wood alternative decking products to the
residential market have increased at a compounded annual growth rate of over
25%.     
 
  The growth in demand for residential decking reflects the increasing
popularity of decks as a means of extending living areas and providing outdoor
recreation and entertainment spaces. Residential decking purchases include the
installation of new and replacement decks for existing homes, construction of
decks for new homes and repair of existing decks. An industry study estimates
that more than three million decks are built each year. Deck repair,
modernization and replacement are expected to increase as existing decks age.
 
  The majority of decks are built for existing homes as new additions or to
replace other decks. During periods of economic uncertainty, when spending on
discretionary items is reduced, many homeowners forego the purchase of new
homes and choose to improve their existing residences. Adding a deck has
become one of the most popular home improvement projects. Construction of
 
                                      30
<PAGE>
 
decking is a relatively low-cost means of adding livable space, and industry
studies indicate that decking improvements generally return a significant
percentage of their cost at the time of resale. The Company estimates that the
installation cost of a majority of decks ranges from $2,000 to $5,000. More
than half of all decks are constructed one to five years after a home is
purchased. Accordingly, there is typically an increased demand for decking in
the five-year period following a peak in home sales. The Company believes
that, because residential deck construction is not primarily tied to new home
activity, the residential decking market historically has not experienced the
high level of cyclicality common to businesses in the new home construction
and building materials industries.
 
  The Company estimates that contractors, including homebuilders, install
approximately 60% of all residential decks, accounting for approximately 70%
of the board feet used. The balance of residential decks are installed by "do-
it-yourself" homeowners. Contractors generally either specialize in deck
installation or build decks in connection with new home construction or home
improvement and remodeling projects. Contractor-installed decks on average are
larger and more elaborate than decks installed by homeowners.
 
  Commercial decks are constructed for restaurants, hotels, nature walks and
boardwalks. These decking applications typically have more demanding design
and installation requirements than those for residential decking. Product
liability and maintenance costs are major issues for commercial installations.
As a result, safety and maintenance features of decking products particularly
influence buying decisions in this market segment.
 
  The following table sets forth, in board feet of lumber, the percentage of
1997 factory sales to the decking market generated by each product category
indicated:

</TABLE>
 
  More than 75% of wooden decks are fabricated from southern yellow pine,
which is pressure-treated with insecticides and other chemicals to create
resistance to insect infestation and decay. The balance of the wood decking
segment is primarily divided between redwood and cedar products. The 100%
plastic decking products utilize polyethylene, fiberglass and polyvinyl
chloride ("PVC") as raw materials. Wood/plastic composites are produced from a
combination of wood fiber and polyethylene or other commonly used polymers.
Growing consumer awareness of the product attributes of non-wood decking
alternatives and the decline in lumber quality and quantity have contributed
to increased sales of 100% plastic lumber and wood/plastic composites for
decking.
 
  Production and distribution operations in the decking market are highly
fragmented. Treated southern yellow pine is produced by wood preservers that
operate approximately 550 treatment plants in the United States. These
treated-wood suppliers are predominantly small companies with a regional
distribution focus. An estimated six to eight companies supply redwood to the
decking market, while cedar supplies are produced by a few large suppliers and
approximately 20 to 30 small, regional suppliers that market varieties of
cedar grown in their areas. In 1997, according to an industry study, non-wood
decking materials were manufactured by approximately 20 companies, of which
less than half had annual revenues of over $5 million.
 
  Distributors of wood decking materials typically supply lumber to lumber
yards and home center outlets, who in turn supply the materials to home
builders, contractors and homeowners. Manufacturers of non-wood decking
alternatives also generally use these distribution channels, since
 
                                      31
<PAGE>
 
many such alternative products can be stacked, stored and installed like wood
products. Certain non-wood decking alternatives, however, are sold to
specialty dealers who provide the special selling support needed to build
consumer awareness of new products.
 
  Wood decking products generally are not associated with brand
identification. The primary softwoods used for decking (treated southern
yellow pine, redwood and cedar) are sold as commodities graded according to
classifications established by the U.S. Department of Commerce. Pricing is
based on species, grade, size and level of chemical treatment, if any. There
generally is no pricing differentiation based on brand, although certain wood
preservers have attempted to brand their treated wood products. The Company
believes that these companies, which it estimates represent less than 5% of
the treated wood market, have not established meaningful brand name
recognition.
 
Competitive Strengths
 
  The Company believes that its primary competitive strengths are the
following:
   
  Superior Product. Trex offers a number of significant advantages over wood
decking products. Trex eliminates many of wood's major functional
disadvantages, which include warping, splitting and other damage from
moisture. Trex requires no sealing to protect against moisture damage,
provides a splinter-free surface and needs no chemical treatment against
insect infestation. These features of Trex eliminate the on-going maintenance
requirements for a wood deck and make Trex less costly than wood over the life
of the deck. Like wood, Trex is slip-resistant, even when wet, can be painted
or stained and is not vulnerable to damage from ultraviolet rays. The special
characteristics of Trex, including resistance to splitting, flexibility and
ease and consistency of machining and finishing, facilitate deck installation,
reduce contractor call-back and afford customers a wide range of design
options.     
   
  Brand Name Development. The Company has invested over $10 million during the
last three years to develop Trex as a recognized brand name in the residential
and commercial decking market. The Company's marketing strategy has been to
promote Trex among consumers and contractors as a premium decking product. The
Company uses extensive print and television advertising to build brand
awareness among homeowners and commercial users and targets decking
contractors with advertisements in leading building and remodeling magazines.
Brand name recognition helps to generate demand for Trex directly among
consumers and also among distributors and dealers, who recommend Trex to
contractors and other consumers. The Company believes that its branding
strategy promotes product differentiation of Trex in a market which is not
generally characterized by brand identification and enables the Company both
to command premium prices and to maintain price stability for Trex.     
   
  Extensive Distribution Network. The Company has developed an extensive
distribution network which complements its branding strategy and focus on the
contractor-installed market segment. At December 31, 1998, the Company sold
Trex through approximately 55 wholesale distribution locations. At the same
date, the Company's distributors marketed Trex to approximately 2,000 dealer
outlets, which directly service contractors and consumers. The Company selects
distributors based upon their anticipated commitment to Trex, and the
Company's distribution network devotes significant resources to promoting and
selling Trex. All distributors have appointed a Trex specialist, regularly
conduct dealer training sessions, fund demonstration projects and participate
in local advertising campaigns and home shows. These distributors generally
sell Trex as their only non-wood decking alternative and agree in their
distribution agreements with the Company not to market other wood/plastic
composites with the same applications as Trex.     
 
  Investment in Manufacturing Process and Product Development. Production of a
non-wood decking alternative like Trex requires significant capital
investment, special process know-how and
 
                                      32
<PAGE>
 
   
time to develop. The Company has invested approximately $34 million and six
years in expansion of its manufacturing capacity, manufacturing process
improvements, new product development and product enhancements. The Company's
investment of time and capital has enabled it to increase the number of
production lines from one to eight and its manufacturing line production rates
by more than 200% since 1992, has facilitated the Company's development of new
products and has produced improvements in the dimensional consistency, surface
texture and color uniformity of the Trex product line.     
 
  Building Code Listing. Trex is the only non-wood decking alternative to
receive a product building code listing either from the NES or from any of the
three NES regional members that establish construction standards in the United
States. Since receiving its NES listing in 1995, Trex has been the only non-
wood alternative decking product published in all major code books throughout
the country. The Company's listing facilitates the acquisition of building
permits by residential consumers of Trex. The Company believes that its
listing promotes customer and industry acceptance of Trex as a substitute for
wood in decking.
 
  Experienced Management Team. The Company is managed by four experienced
senior executives who led the buyout of Mobil's Composite Products Division in
1996. The Company's executives have managed billion-dollar operations as well
as smaller, high-growth divisions and product rollouts within and outside of
Mobil. They have approximately 75 years of combined management experience at
Mobil across a wide range of management functions.
 
Growth Strategies
 
  The Company's goals are to continue to be the leading producer of a superior
non-wood decking alternative product, to increase its market share of the
decking market and to expand new products and geographic markets. To attain
these goals, the Company employs the following strategies:
 
  Continue Brand Name Development. The Company plans to increase its
investment in, and the resources devoted to, development of the Trex brand.
The Company's branding efforts will focus on implementation of enhanced
integrated advertising, public relations and trade programs. The Company's
sales growth in the decking market will largely depend on converting demand
for wood products into demand for Trex. Accordingly, the Company's branding
strategy will continue to emphasize the advantages of Trex over wood decking
products. The Company's brand building programs also are designed to support
the positioning of Trex as a premium product in the decking market.
   
  Expand Distribution Coverage. The Company intends to establish comprehensive
national coverage for Trex. To achieve this objective, the Company expects to
increase the number of dealer outlets selling Trex over the next three years
by 50% to approximately 3,000 outlets. The Company will seek to expand its
dealer network by adding new distributors and increasing the number of its
wholesale distribution locations to approximately 75 distribution locations
from its base of approximately 55 at December 31, 1998.     
   
  Increase Production Capacity. Currently, customer demand for Trex exceeds
the Company's manufacturing capacity. To support sales growth and improve
customer service, the Company plans to increase output by increasing
productivity in its existing facility in Winchester, Virginia and by beginning
production in an additional manufacturing facility near Reno, Nevada in the
third quarter of 1999. The Company recently augmented its production capacity
at the Winchester facility by adding one new production line in December 1998
and a second new production line in January 1999. The addition of these two
production lines will enable the Company to increase its current manufacturing
capacity by approximately a 40% by mid-1999. With the second manufacturing
facility in operation, the Company expects by the end of 1999 to double its
production capacity from the level sustained in December 1998.     
 
                                      33
<PAGE>
 
   
  Invest in Process and Product Development. The Company will continue to make
substantial investments in process and product development to support new
products and improve product consistency, reduce manufacturing costs and
increase operating efficiencies. In the third quarter of 1998, the Company
centralized its research and development operations in the Trex Technical
Center, a 30,000 square foot building adjacent to its Winchester manufacturing
facility.     
   
  Increase New Product Development and Export Markets. As part of its long-
term growth strategy, the Company will continue to develop opportunities for
Trex in new products and product applications and in geographic markets beyond
the Company's U.S. base. In 1998, the Company derived approximately 15% of its
net sales from sales of Trex for non-decking applications, including
industrial block flooring, applications for parks and recreational areas,
floating and fixed docks and other marine applications, and landscape edging.
The Company believes that the product characteristics of Trex are well suited
to satisfy the diverse appearance, performance and safety requirements of
these and other potential product applications. In expanding its geographic
scope of operations, the Company plans to increase exports to Canada, where it
currently has limited sales, and explore export opportunities in the
Caribbean, Latin America and selected parts of Europe.     
 
Products
 
  The Company manufactures Trex Wood-Polymer lumber, a composite product that
offers an attractive appearance and the workability of wood without wood's on-
going maintenance requirements or functional disadvantages. Trex is
manufactured in a proprietary process that combines waste wood fibers and
reclaimed polyethylene. Trex is produced in popular lumber sizes and is
currently sold in three colors: Natural, Winchester Grey and Woodland Brown.
   
  Approximately 85% of the Company's 1998 net sales were derived from sales of
Trex to the residential and commercial decking market. Trex also has a number
of non-decking product applications, which generated the remaining 15% of the
Company's 1998 net sales. These applications currently include blocks to cover
and protect concrete sub-floors in heavy industrial plants; applications for
parks and recreational areas, including playground structures, picnic tables
and benches, fencing and theme park applications; floating and fixed docks and
other marine applications; and landscape edging. Trex does not have the
tensile strength of wood and, as a result, is not used as a primary structural
member in posts, beams or columns used in a deck's substructure.     
 
Sales and Marketing
   
  The Company's marketing activities at December 31, 1998 were conducted by 17
employees, of whom 12 were field sales representatives providing nationwide
sales coverage. The sales representatives, who are assigned to particular
geographic markets, are primarily responsible for servicing the Company's
wholesale distributors, assisting in dealer and contractor training, meeting
with architects and specifiers and providing support at regional home shows
and other consumer events. The Company maintains a commission program for its
sales force which is designed to reward achievement of sales goals and to
promote sales growth.     
 
  The Company's sales growth in the decking market will largely depend on
converting demand for wood products into demand for Trex. Accordingly, the
Company's branding strategy will continue to emphasize the advantages of Trex
over wood decking products. The Company's marketing efforts are focused on the
residential and commercial decking market. The Company has implemented a two-
pronged marketing program directed at consumers and contractors. The Company
seeks to develop consumer brand awareness and contractor preference to
generate demand for Trex among dealers and distributors, who then recommend
Trex to other contractors and consumers. The following are the key elements of
the Company's marketing program:
   
  Consumer Advertising. The Company engages in extensive television
advertising. In 1998, the Company ran network and cable television
advertisements over an 18-week period during     
 
                                      34
<PAGE>
 
   
the first half of the year featuring 30-second spots on shows such as ABC's
Good Morning America and NBC's Today.     
 
  The Company also advertises Trex extensively in popular magazines, including
Better Homes & Gardens, Sunset and Martha Stewart Living. The 1998 print
advertising campaign includes full-page color magazine advertisements
featuring the Company's new spokesman, Willard Scott, of NBC's Today.
   
  Public Relations. The Company employs a public relations firm to stimulate
interest in Trex by the print and broadcast media. During 1998, print and
broadcast stories featuring Trex generated a total of 125 million
"impressions," which represent potential viewings.     
 
  Trade Advertising and Promotion. To build a brand name for Trex with decking
contractors, the Company reaches a professional building audience through
advertisements in leading building and remodeling magazines, including
Builder, Building Products, Fine Homebuilding, Journal of Light Construction
and other well-known publications.
 
  Homebuilder Program. In 1998, the Company inaugurated a program to provide
promotional allowances and display materials to homebuilders who use Trex for
their model home decks and agree to promote Trex. Over 60 homebuilders
currently participate in the program.
 
  Trade and Home Shows. The Company annually exhibits Trex at five major trade
shows for homebuilders, contractors and specifiers that have a total
attendance of approximately 200,000. The Company also exhibits its product
line at major regional home and garden shows. Distributors, dealers and
contractors experienced in Trex provide additional support by exhibiting Trex
at smaller local home shows.
 
  Showcase Projects. Trex obtains further brand name recognition through its
association with highly publicized showcase projects. Trex has been used in a
number of such projects, including the Presidential Trail at Mount Rushmore,
the Toronto Boardwalk on Lake Ontario Shores, the Florida Everglades Walkways
and the Grand Canyon Education Center.
 
  Consumer Research. From time to time, the Company commissions consumer
research studies to gain a better understanding of the needs of the decking
market, the ability of Trex to meet those needs relative to competitive
products and consumer acceptance of Trex as a decking material.
 
Distribution
   
  Approximately 95% of Trex net sales are made through the Company's wholesale
distribution network. At December 31, 1998, the Company sold its Trex product
line to 22 wholesale companies operating from approximately 55 distribution
locations. At the same date, the Company's distributors marketed Trex to
approximately 2,000 dealer outlets across the United States. Although the
Company's dealers sell to both homeowners and contractors, their sales efforts
are primarily directed at professional contractors, remodelers and
homebuilders. The remaining 5% of the Company's net sales are made directly to
industrial floor fabricators, playground material distributors and other
accounts.     
 
  Wholesale Distributors. The Company believes attracting wholesale
distributors who are committed to Trex and the Trex marketing approach and who
can effectively sell Trex to contractor-oriented lumber yards is important to
its future growth. The Company believes its distributors are able to provide
value-added service in marketing Trex because they sell premium wood decking
products and other building supplies, which typically require product training
and personal selling efforts.
 
  Pursuant to its agreement with each wholesale distributor, the Company
appoints the distributor on a non-exclusive basis to distribute Trex within a
specified area. The distributor generally purchases Trex at
 
                                      35
<PAGE>
 
   
the Company's prices in effect at the time the Company ships the product to
the distributor. The distributor is required to maintain specified minimum
inventories of Trex during certain portions of each year. Upon the expiration
of the initial one-year term, the agreement is automatically renewed for
additional one-year terms unless either party provides notice of termination
at least 60 days before the expiration of any renewal term. The distributor
may terminate the agreement at any time upon 60 or 90 days' notice, while the
Company may terminate the agreement upon 60 or 90 days' notice or immediately
upon the happening of certain events, including a failure by the distributor
to maintain the required minimum inventories of Trex.     
 
  The Company requires its wholesale distributors to contribute significant
resources to support Trex. All wholesale distributors have appointed a Trex
specialist, regularly conduct dealer training sessions, fund demonstration
projects and participate in local advertising campaigns and home shows. The
Company sponsors intensive two-day training seminars to help train Trex
specialists.
   
  In 1997 and 1998, the Company generated in excess of 10% of its net sales to
each of five wholesale distribution companies: Capital Lumber Company, Furman
Lumber, Inc., OrePac Building Products, Inc., Plunkett-Webster Inc. and
Snavely Forest Products, Inc. These distributors collectively accounted for
approximately 68% and 74% of the Company's net sales in 1997 and 1998,
respectively. Other than Plunkett-Webster, Inc., which accounted for between
15% and 20% of the Company's net sales in both years, each of such
distributors accounted for less than 15% of the Company's net sales. In 1996,
the Company generated in excess of 10% of its net sales to each of three
wholesale distribution companies: Capital Lumber Company, Plunkett-Webster,
Inc. and Snavely Forest Products, Inc. These distributors collectively
accounted for approximately 52% of the Company's net sales in 1996. Capital
Lumber Company and Plunkett-Webster, Inc. each accounted for between 15% and
20% of the Company's 1996 net sales, while Snavely Forest Products, Inc.
accounted for less than 15% of such net sales.     
 
  To augment its dealer outlets, the Company plans to add new distributors and
increase the number of its wholesale distribution locations over the next
three years to approximately 75.
   
  Retail Lumber Dealers. Of the approximately 25,000 retail outlets in the
United States that sell lumber, approximately 5,000 are independent lumber
yards that emphasize sales to contractors and are the primary market for Trex.
Although there is demand for Trex from both the "do-it-yourself" homeowner and
contractor, the Company's sales efforts emphasize the contractor-installed
market to achieve premium product positioning for Trex and to ensure that the
installations will have professional craftsmanship. The Company's retail
dealers generally provide sales personnel trained in Trex, contractor
training, inventory commitment and point-of-sale display support. To establish
comprehensive national coverage for Trex, the Company plans to increase the
number of its dealer outlets over the next three years from approximately
2,000 at December 31, 1998 to approximately 3,000.     
 
  Contractor Training. The Company has provided training about Trex to over
20,000 contractors since 1995. Contractors receive a Trex Contractor Kit
containing a product handbook, sales literature and product samples as part of
their training. The Company has established a "Builders Club" to strengthen
its relationship with premium decking contractors.
 
  Dealer Locator Service and Web Site. The Company maintains a toll-free
telephone service for use by consumers and building professionals to locate
the closest dealer offering Trex and to obtain product information. The
Company uses these calls to generate sales leads for contractors, dealers,
distributors and Trex sales representatives. The Company also analyzes caller
information to assess the effectiveness of its promotional and advertising
activities.
 
  As an additional source of information to consumers, dealers and
distributors, the Company operates a Web site, which provides product
installation information, handling instructions, a dealer locator service,
photographs of showcase installations, technical reports and other
information.
 
  Shipment. The Company ships Trex to distributors by truck and rail. Western
distributors principally receive shipments by rail. Distributors pay all
shipping and delivery charges.

Manufacturing Process
   
  Trex is manufactured at the Company's 100,000 square foot facility in
Winchester, Virginia. The facility currently has eight production lines, each
of which is highly automated and on average requires fewer than five employees
to operate per shift.     
   
  In 1998, the Company's Winchester facility had a total capacity of 155
million pounds per year of finished product and was operating at its full
capacity. To support sales growth and improve customer service, the Company
added one new production line to the facility in December 1998 and a second
new production line in January 1999. The Company expects that, after the two
new lines achieve their full operating capacity in mid-1999, the addition of
these lines will increase the facility's total capacity to 215 million pounds
of finished product per year, or approximately 40% over the December 1998
level.     
   
  In December 1998, the Company acquired the site for an additional
manufacturing facility in Fernley, Nevada, which is located approximately 30
miles east of Reno. The Company estimates that the total cost of the site
acquisition, construction and equipping of the new facility will be
approximately $19.6 million. The Company expects to fund this cost with
approximately $6.7 million of borrowings under site acquisition and
construction loans, approximately $3.8 million from the net proceeds of the
Offering and approximately $9.1 million from its operating cash flow and
borrowings under its revolving credit facility. Construction of the facility
began in January 1999. The Company anticipates that the new facility will
begin production in the third quarter of 1999. The facility will occupy
150,000 square feet and will initially have two production lines. With its
second manufacturing facility in operation, the Company expects by the end of
1999 to double its production capacity from the level sustained in December
1998. See "Risk Factors--Ability to Increase Manufacturing Capacity" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."     
 
  Trex is manufactured from waste wood fiber and reclaimed polyethylene
("poly"). The composition of Trex Wood-Polymer lumber is approximately 50%
wood fiber and 50% reclaimed poly material. The Company uses wood fiber
purchased from wood working factories, mills and pallet recyclers, most of
which are located within a 200-mile radius of the Company's Winchester
facility. Poly material used in the production of Trex consists primarily of
reclaimed grocery sacks and stretch film, which the Company purchases from
suppliers throughout the United States. See "Suppliers."
 
  The Trex manufacturing process involves mixing wood particles with plastic,
heating and finally extruding (or forcing) the highly viscous and abrasive
material through a profile die. The extruded product is cooled in a water bath
and cut to its finished length. Waste created during manufacturing is recycled
into the production process. The finished boards are placed on a cooling
conveyor and proceed to finished goods inspection, packaging and storage.
   
  The Company has made substantial investments in manufacturing process
improvements. As a result of these investments, production line rates, which
are measured in pounds of finished product per production hour, have increased
over 200% since 1992. The Company also has broadened the range of raw
materials that can be used to produce Trex by developing hardware capable of
utilizing different forms of poly material to produce a consistent final
product. The Company has obtained a patent for a process of preparing the raw
materials for the manufacturing phase of production and a second patent for
another manufacturing process improvement. The patent protection for both
processes will extend until 2015.     
 
  Trex is the only wood/plastic composite product to receive a building code
listing either from the NES or from any of its three regional members that
establish construction standards in the United States (Building Officials &
Code Administrators International, Inc., International Conference on Building
Officials and Southern Building Code Congress International, Inc.). In
conjunction with its NES listing, the Company
 
                                      37
<PAGE>
 
maintains a quality control testing program that is monitored by an NES-
approved independent inspection agency. Under this program, the Company tests
one board from every other production bundle to determine whether it meets the
detailed, published criteria for code listing. Representatives of the
inspection agency conduct unannounced monthly on-site audits of these program
records to assure conformity to testing and to check test results. The Company
believes that currently a minimum of 18 months would be required for a
manufacturer of a competitive product which has not yet started the listing
approval process to complete all phases of the process for its product. See
"Risk Factors--Competition."
 
Suppliers
 
  The production of Trex requires the supply of wood fiber and polyethylene
from reclaimed grocery sacks and stretch film. The Company satisfies virtually
all of its current wood fiber requirements from six regional suppliers. The
Company purchases its supplies of poly material from multiple locations
throughout the country, including supermarkets and distribution centers.
   
  Wood Fiber. In 1998, the Company consumed 101 million pounds of wood fiber.
Suppliers accounting for over 90% of the Company's wood fiber purchases are
located within a 200-mile radius of the Company's Winchester, Virginia
facility. Convenient access to available wood fiber supplies was one of the
Company's principal site selection criteria for its second manufacturing
facility, which will be located near Reno, Nevada. Although it has not yet
entered into supply agreements for the new facility, the Company believes that
it will be able to satisfy substantially all of the facility's wood fiber
requirements from suppliers located within a 500-mile radius of the facility.
    
  Woodworking plants or mills are the Company's preferred suppliers of wood
fiber because the waste wood fiber produced by these operations contains
little contamination and is low in moisture. These facilities generate wood
fiber as a byproduct of their manufacturing operations. To minimize its
purchase costs, the Company seeks to provide the manufacturing facilities with
prompt and reliable removal service using Company-provided equipment.
   
  Four suppliers accounted individually for more than 10% and collectively for
approximately 80% of the Company's 1998 wood fiber purchases: American
Woodmark, American Wood Fiber, Plumly Lumber and Coastal Lumber. The Company
obtains its wood fiber supplies for a fixed annual price under multi-year
contracts that are terminable by either party upon 30 days' notice. Based on
its discussions with wood fiber suppliers and its analysis of industry data,
the Company believes that, if its contracts with one or more of its current
suppliers were terminated, the Company would be able to obtain adequate
supplies of wood fiber at an acceptable cost from its other current suppliers
or from new suppliers.     
   
  Poly Material. In 1998, the Company consumed 87 million pounds of poly
material, which was primarily composed of reclaimed grocery sacks and stretch
film. Approximately two billion pounds of poly film are used in the
manufacture of grocery sacks and stretch film in the United States each year.
The Company will seek to meet its future needs for poly material from
expansion of its existing supply sources and the development of new sources,
including post-industrial waste and plastic paper laminates.     
 
  The Company purchases plastic sacks primarily from large grocery supermarket
chains, which have recycling programs that facilitate and encourage plastic
sack returns. Approximately 5% of all grocery sacks nationwide are returned.
The existing industry practice is for reclaimed sack purchasers, such as the
Company, to absorb freight and handling costs after the sacks are picked up
from the chains' distribution centers. The Company picks up the plastic
grocery sacks at the distribution centers and stores the sacks in warehouses
until it uses them in its production process.
 
  Stretch film is used to stabilize pallet loads to avoid damage during
shipping and handling. The Company collects stretch film from distribution
centers that service the grocery and other industries,
 
                                      38
<PAGE>
 
including furniture, machinery, parts and soft goods businesses. Suppliers of
stretch film save on waste disposal costs by selling the bundled film to the
Company.
   
  No supplier sold 10% or more of the poly material purchased by the Company
in 1998. The Company generally acquires poly material by purchase order at
prices which are fixed annually.     
   
  The Company has entered into a six-year contract with a potential supplier
of poly material derived from a source not previously accessed by the Company.
The contract obligates the Company to purchase up to $3.3 million of poly
material annually at a specified price per pound during the contract term. The
Company is unable to determine the amount of poly material it will obtain
under the contract because the supplier has not yet commenced operations and
will utilize a new production process. The Company is scheduled to receive its
first delivery under the contract in mid-1999. The Company has the option to
renew the contract for an additional six years on the same terms and
conditions.     
 
Competition
 
  The residential and commercial decking market in which the Company
principally operates is highly competitive. As a wood/plastic composite
product, Trex competes with wood, other wood/plastic composites and 100%
plastic lumber for use as decking. The primary competition for Trex is wood
decking, which accounted for approximately 97% of 1997 decking sales (measured
by board feet of lumber). The conventional lumber suppliers with which the
Company competes in many cases have established ties to the building and
construction industry and have well-accepted products. Many of the Company's
competitors in the decking market that sell wood products have significantly
greater financial, technical and marketing resources than the Company. Trex
currently represents over half of the non-wood segment and competes with other
wood/plastic composites as well as with 100% plastic products that utilize
polyethylene, fiberglass and PVC as raw materials.
 
  The Company's principal competitors in the non-wood decking alternative
market include Advanced Environmental Recycling Technologies, Inc., Crane
Plastics, Eaglebrook Plastics, Inc., Royal Crown Limited and U.S. Plastic
Lumber Corporation. Trex is the only non-wood decking alternative to receive a
product building code listing from the NES or any its three regional members.
A product building code listing covers all uses of a product meeting the
specified design criteria. The Company is aware of one manufacturer of
wood/plastic composites, Advanced Environmental Recycling Technologies, Inc.,
that has publicly announced it has applied for a regional application listing
for its products and of at least four manufacturers that have applied for
regional application listings for their 100% plastic lumber products. The four
manufacturers include Outdoor Technologies, Inc., ZCL Composites, Thermal
Industries Inc. and Teck-Rail Vinyl Guardrail System. An application listing
covers specific uses of the listed products. Any non-wood decking alternative
product receiving a listing could be more competitive with Trex. The Company's
ability to compete depends, in part, upon a number of factors outside its
control, including the ability of its competitors to develop new non-wood
decking alternatives which are competitive with Trex.
 
  The Company believes that the principal competitive factors in the decking
market include product quality, price, maintenance cost and consumer awareness
of product alternatives. The Company believes it competes favorably with
respect to these factors based on the low maintenance requirements and other
attributes of Trex compared to wood and 100% plastic products, the Trex brand
name, the Company's extensive distribution network and the Trex NES building
code listing.
 
  Of the wood lumber which constituted approximately 97% of the total decking
market in 1997, over 75% is pressure-treated southern yellow pine. Southern
yellow pine is used for decking because its porosity allows it readily to
accept the chemicals used in the treating process that creates resistance to
rotting and insect infestation. The chemical compound used to treat wood is
typically chromated copper arsenate ("CCA"), an EPA-registered pesticide. The
same porosity makes southern yellow pine susceptible to taking on moisture,
which causes the lumber to warp, crack, splinter and expel fasteners. The
balance
 
                                      39
<PAGE>
 
of the wood decking segment is primarily divided between redwood and cedar,
with some amounts of treated fir and exotic hardwoods. Because old, slow-
growth timber has been depleted, new, fast-growth varieties predominate. These
varieties do not have the natural decay resistance or close rings of old,
slow-growth timber, causing them to be more susceptible to rot, insect
infestation, splintering and warping.
 
  Trex also competes with decks made from 100% plastic lumber. Although there
are several companies in the United States that manufacture 100% plastic
lumber, total factory sales to the decking market in 1997 are estimated at
only $20 million (18 million board feet). A number of factors have limited the
success of 100% plastic lumber manufacturers, including a less efficient
manufacturing process, inconsistent product quality, and physical properties
not considered suitable for decking, such as higher thermal expansion and
contraction, poor slip resistance and an appearance viewed by some homeowners
as unattractive.
   
  There are approximately five manufacturers of wood/plastic composite lumber
in addition to the Company. Some of these manufacturers participate in the
decking market only on a limited basis. The Company estimates that Trex
accounted for more than 80% of 1998 total factory sales of wood/plastic
composites to the decking market.     
 
  The following chart compares certain attributes of Trex to the
characteristics of treated wood and 100% plastic products:

  The Company believes that Trex offers cost advantages when compared with
certain other types of decking materials. Although a contractor-installed Trex
deck built in 1998 using a pressure-treated wood substructure generally cost
10% to 15% more than a deck made entirely from pressure-treated wood, Trex
eliminates the on-going maintenance required for a pressure-treated deck and
is, therefore, less costly over the life of the deck. The Company believes
that its manufacturing process and utilization of relatively low cost raw
material sources also provide Trex with a competitive cost advantage relative
to other wood/plastic composite products.     
 
                                      40

Government Regulation
 
  The Company is subject to federal, state and local environmental regulation.
The emissions of particulates and other substances from the Company's
manufacturing facility must meet federal and state air quality standards
implemented through air permits issued to the Company by the Department of
Environmental Quality of the Commonwealth of Virginia. The Company's facility
is regulated by federal and state laws governing the disposal of solid waste
and by state and local permits and requirements with respect to waste water
and storm water discharge. Compliance with environmental laws and regulations
has not had a material adverse effect on the Company's business, financial
condition or results of operations.
 
  The Company's operations also are subject to work place safety regulation by
the U.S. Occupational Safety and Health Administration and the Commonwealth of
Virginia. The Company's compliance efforts include safety awareness and
training programs for its production and maintenance employees.
 
Intellectual Property
   
  The Company's success depends, in part, upon its intellectual property
rights relating to its production process and other operations. The Company
relies upon a combination of trade secret, nondisclosure and other contractual
arrangements, and patent, copyright and trademark laws, to protect its
proprietary rights. The Company has made substantial investments in
manufacturing process improvements which have enabled it to increase
manufacturing line production rates, facilitated the Company's development of
new products and produced improvements in the dimensional consistency, surface
texture and color uniformity of Trex. The Company has obtained a patent for a
process of preparing the raw materials for the manufacturing phase of
production and a second patent for another manufacturing process improvement.
The patent protection for both processes will extend until 2015. The Company
has been granted a federal registration for the Trex trademark by the U.S.
Patent and Trademark Office and has filed applications for the federal
registration of its Easy Care Decking and Wood-Polymer trademarks. Federal
registration of trademarks is effective for an initial period of 20 years and
is renewable for as long as the Company continues to use the trademarks. The
Company considers its trademarks to be of material importance to its business
plans. The Company has not registered any of its copyrights with the U.S.
Copyright Office, but relies on the protection afforded to such copyrights by
the U.S. Copyright Act. That law provides protection to authors of original
works, whether published or unpublished, and whether registered or
unregistered. The Company enters into confidentiality agreements with its
senior employees and limits access to and distribution of its proprietary
information. There can be no assurance that the steps taken by the Company in
this regard will be adequate to deter misappropriation of its proprietary
information or that the Company will be able to detect unauthorized use and
take appropriate steps to enforce its intellectual property rights. See "Risk
Factors--Intellectual Property."     
 
  In 1992, before the Company's buyout of Mobil's Composite Products Division,
Mobil brought an action in the U.S. District Court for the District of
Delaware seeking a declaratory judgment that four patents issued to Advanced
Environmental Recycling Technologies, Inc. ("AERT"), a manufacturer of
wood/plastic composite products, were invalid, were not infringed by Mobil in
connection with its wood/plastic composite (now known as Trex) and were
unenforceable. Mobil brought this action in response to statements by AERT
that Mobil infringed AERT's patents. AERT counterclaimed against Mobil for
alleged infringement of two of the AERT patents and for alleged violations of
antitrust and trade regulation laws.
 
  Following a trial in early 1994, the district court held that Mobil did not
infringe either of the two AERT patents that were the subject of the
counterclaim and rendered a verdict for Mobil that each of the four AERT
patents was invalid and unenforceable. On an appeal of this judgment by AERT,
the U.S. Court of Appeals for the Federal Circuit affirmed the district
court's judgment that Mobil did not infringe the two AERT patents and that two
of the four AERT patents were invalid and unenforceable. The Federal Circuit
vacated the district court's judgment on the remaining two AERT patents on the
grounds that there was no case or controversy between the parties regarding
infringement of those patents. AERT has filed a motion for a new trial, which
is pending before the district court. The district court also still has
pending before it AERT's non-patent counterclaims against Mobil. No
proceedings on those claims are currently scheduled.
 
                                      41
<PAGE>
 
  In June 1998, the U.S. Patent and Trademark Office issued to AERT a patent
which is a continuation in part of one of the two patent applications that
resulted in the two patents held to be invalid and unenforceable in the
district court action. The Company believes, based in part on advice of its
legal counsel, that the Company does not infringe this patent.
 
Facilities and Equipment
   
  The Company leases its corporate headquarters in Winchester, Virginia, which
consists of approximately 4,500 feet of office space, on a month-to-month
basis.     
   
  The Company owns its manufacturing facility in Winchester, Virginia, which
contains approximately 100,000 square feet of manufacturing space, and
approximately 7.5 acres of outside open storage in a lot located across from
the manufacturing facility.     
   
  The Company leases storage warehouse space, which totals 75,000 square feet,
pursuant to leases with expiration dates from December 1999 to July 2000. The
Company currently occupies approximately 30,000 square feet in the Trex
Technical Center, which it purchased in the fourth quarter of 1998.     
   
  Equipment and machinery used by the Company in its operations consist
principally of plastic and wood conveying and process equipment. The Company
owns all of its manufacturing equipment. The Company also operates
approximately 30 wood trailers pursuant to operating leases with expiration
dates from 1999 to 2003 and approximately 20 forklift trucks pursuant to
operating leases with expiration dates from 2000 to 2001.     
   
  The Company regularly evaluates the capacity of its various facilities and
equipment and makes capital investments to expand capacity where necessary. In
1998, the Company spent a total of $17.1 milllion on capital expenditures,
including $7.4 million for additional production equipment in its Winchester
facility. The Company has acquired the site for, and in January 1999 began
construction of, a second manufacturing facility, which will be located near
Reno, Nevada and which the Company expects to begin production in the third
quarter of 1999. See "--Manufacturing Process." The Company currently
estimates that its aggregate capital expenditures in 1999 will total
approximately $20.3 million, most of which will be used to construct and equip
the new facility.     
 
Employees
   
  At December 31, 1998, the Company had 217 full-time employees, of whom 23
were employed in corporate management and administration, 17 were employed in
sales and marketing, six were employed in research and development and 171
were employed in manufacturing operations. Of such employees, 142 were hourly
employees engaged in manufacturing activities in the Company's Winchester
facility. The Company's employees are not covered by a collective bargaining
agreement. The Company believes that its relationships with its employees are
good.     
 
Legal Proceedings
   
  The Company has been named as a co-defendant in a suit filed on December 7,
1997 in the U.S. District Court for the Eastern District of Pennsylvania. The
plaintiff, the owner of a ship moored in Philadelphia, alleges that design
defects in a Trex decking product caused buckling of decking installed on the
ship as part of a renovation project. The plaintiff seeks damages in an
unspecified amount against the Company based on claims of strict liability,
misrepresentation, breach of warranties, gross negligence, indemnification and
violation of the New Jersey Consumer Fraud Act. Trex has denied liability on
the grounds, among others, that the alleged damage to the decking resulted
from poor design and improper installation. The parties have conducted certain
discovery proceedings. A trial date for the suit is scheduled for June 1999.
    
  From time to time, the Company is involved in litigation and proceedings
arising out of the ordinary course of its business. Except as set forth above,
there are no pending material legal proceedings to which the Company is a
party or to which the property of the Company is subject.

1999 Stock Option and Incentive Plan     
   
  The Company's Stock Incentive Plan provides for the grant of options that
are intended to qualify as "incentive stock options" under Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), to employees of the
Company and any future subsidiaries, as well as for the grant of non-qualified
options, restricted Common Stock, restricted units of Common Stock,
unrestricted Common Stock and stock appreciation rights (collectively,
"Awards") to employees, non-employee directors and other individuals whose
participation in the Stock Incentive Plan is determined to be in the Company's
best interests. The Stock Incentive Plan authorizes the issuance of 1,400,000
shares of Common Stock (subject to adjustment in the event of a stock split,
stock dividend, merger, reorganization or similar transaction). The maximum
number of shares of Common Stock subject to options that may be granted to any
individual under the Stock Incentive Plan is 500,000 shares (subject to such
adjustment). The Stock Incentive Plan will be administered by the Compensation
Committee of the Board of Directors, which has the authority, subject to the
provisions of the Stock Incentive Plan, to determine the terms of any Awards.
As of the date of this Prospectus, no Awards have been made under the Stock
Incentive Plan.     
          
  Upon the consummation of the Offering, the Company intends to grant to
certain employees non-qualified options under the Stock Incentive Plan to
purchase up to an aggregate of 125,000 shares of Common Stock. No such options
will be granted to executive officers of the Company. All such options will be
exercisable at a price equal to the initial public offering price of the
Shares. Each     
 
                                      45
<PAGE>
 
   
option will vest with respect to one-fourth of the shares subject to the
option on each of the first, second, third and fourth anniversaries of the
date of grant.     
   
  The Board of Directors may authorize amendment of the Stock Incentive Plan
without stockholder approval except in circumstances prescribed by applicable
law or regulation. The Stock Incentive Plan does not have a termination date,
but no incentive stock options may be granted after the tenth anniversary of
the effective date of the plan.     
   
  Options. An option granted under the Stock Incentive Plan is exercisable
only to the extent that it is vested on the date of exercise. No option may be
exercisable more than ten years from the option grant date, or five years in
the case of an incentive stock option granted to a person who owns more than
10% of the total combined voting power of all classes of stock of the Company
or any subsidiary thereof (a "ten percent stockholder").     
   
  Each option will become vested and exercisable at such times and under such
conditions as the Compensation Committee may approve. The Compensation
Committee may accelerate the vesting of any option in its discretion. The
exercise price per share under each option granted under the Stock Incentive
Plan may not be less than 100% (110% in the case of an incentive stock option
granted to a ten percent stockholder) of the fair market value of the Common
Stock on the option grant date. In the case of incentive stock options, the
aggregate fair market value of the Common Stock (determined on the option
grant date) with respect to which such options are exercisable for the first
time during any calendar year may not exceed $100,000.     
   
  Incentive stock options are non-transferable during the optionee's lifetime,
but non-qualified stock options may be transferred to the spouse, children,
grandchildren, parents and siblings of the optionee, to the extent permitted
by the Compensation Committee.     
   
  Unless otherwise provided by the Compensation Committee, the following
provisions of the Stock Incentive Plan will govern termination of options in
the circumstances described below. Upon termination of a participant's
employment or other relationship with the Company, other than by reason of
death, permanent and total disability or retirement, all unvested options held
by such participant will terminate immediately and all vested options not
exercised will terminate 90 days following the employment termination date. If
a participant dies while employed or providing services to the Company,
terminates his employment or other relationship with the Company by reason of
permanent and total disability or retires, all options held by such
participant which have not previously terminated will fully vest and will be
exercisable for one year thereafter, in the case of death or disability, or
for three years thereafter, in the case of retirement.     
       
          
  Restricted Stock and Restricted Stock Units. Restricted shares of Common
Stock are awards of shares of Common Stock upon which are imposed restricted
periods and restrictions which subject the shares to a substantial risk of
forfeiture as defined in Section 83 of the Code. Restricted Common Stock units
are awards which represent a conditional right to receive shares of Common
Stock in the future and which are subject to the same types of restrictions
and risk of forfeiture as restricted shares of Common Stock. Restricted shares
of Common Stock and restricted Common Stock units will be subject to such
restrictions as the Compensation Committee may impose, including, without
limitation, continuous employment with the Company or any of its future
subsidiaries or the attainment of specific corporate or individual performance
objectives. The restrictions and the restricted period, which generally will
be a minimum of three years, may differ with respect to each recipient of an
Award. An Award of restricted shares of Common Stock or restricted Common
Stock units will be subject to forfeiture if certain events specified by the
Board of Directors occur prior to the lapse of the restrictions. Subject to
the provisions of the Stock Incentive Plan, the Compensation Committee will
determine the terms and conditions of the agreement evidencing each Award of
restricted shares of Common Stock and restricted Common Stock units.     
 
                                      46
<PAGE>
 
   
  Unrestricted Stock. Unrestricted shares of Common Stock are shares that are
free of restrictions other than those imposed pursuant to federal or state
securities laws.     
   
  Stock Appreciation Rights. A stock appreciation right ("SAR") is a right to
receive, in the form of Common Stock, cash or a combination of Common Stock
and cash, the spread or difference between the fair market value of the Common
Stock subject to an option and the option exercise price. SARs may be granted
in conjunction with all or a portion of any option granted under the Stock
Incentive Plan, either at the time of the grant of such option or at any
subsequent time prior to the expiration of such option. The Compensation
Committee will determine at the SAR grant date or thereafter the time or times
at which and the circumstances under which an SAR may be exercised in whole or
in part, the time or times at which and the circumstances under which an SAR
will cease to be exercisable, the method of exercise, the method of
settlement, the form of consideration payable in settlement, whether or not an
SAR will be in tandem or in combination with any other grant, and any other
terms and conditions of any SAR. Exercisability of SARs may be subject to
achievement of one or more of the same performance objectives that apply to
awards of restricted shares of Common Stock or restricted Common Stock units.
SARs issued in connection with incentive stock options are required to meet
additional conditions. SARs are transferable only to the same extent as the
related options.     
       
       
          
1999 Incentive Plan for Outside Directors     
   
  The Company's 1999 Incentive Plan for Outside Directors sets forth the terms
of compensation payable to the Company's non-employee directors ("Outside
Directors") for their service on the Board of Directors. Upon his initial
election or appointment of the Board of Directors, each Outside Director will
receive an option to purchase 1,500 shares of Common Stock. Each Outside
Director will receive an annual fee of $25,000 for service on the Board of
Directors and its committees. The director may elect to receive up to one-half
of this annual fee in cash and up to all of the fee in the form of options to
purchase Common Stock. The value of the options issued in payment of any
portion of an Outside Director's annual fee will be determined pursuant to the
Black-Scholes valuation model.     
   
  The shares of Common Stock issuable upon the exercise of options under the
Outside Director Plan will be issued under the Stock Incentive Plan. The
exercise price per share under each option will be the fair market value of
the Common Stock on the option grant date. The options that will be granted to
the newly appointed Outside Directors upon the consummation of the Offering
will be exercisable at a price equal to the initial public offering price of
the Shares. Each option will vest with respect to one-fourth of the shares
subject to the option on each of the first, second, third and fourth
anniversaries of the date of grant. No option may be exercisable more than ten
years from the option grant date. Options will terminate after the expiration
of specified periods following the termination of the option holder's service
as a director, whether by reason of death, disability, retirement or
otherwise. The Outside Director Plan will be administered by a committee of
the Board of Directors.     
 
Employee Stock Purchase Plan
   
  The 1999 Employee Stock Purchase Plan (the "Employee Stock Purchase Plan"),
which will be implemented upon consummation of the Offering, is intended to
qualify under Section 423 of the Code. The Company has reserved an aggregate
of 300,000 shares of Common Stock for issuance under the Employee Stock
Purchase Plan. The Employee Stock Purchase Plan will permit full-time
employees of the Company and any future subsidiaries who have satisfied
minimum service requirements to purchase Common Stock through payroll
deductions, provided that no employee may purchase more than $25,000 worth of
Common Stock in any calendar year. The purchase price of the Common Stock
under the Employee Stock Purchase Plan will be no less than 85% of the     
 
                                      47
<PAGE>
 
market value of the Common Stock, as calculated in accordance with the
Employee Stock Purchase Plan.
 
Employee Benefit Plans
   
  The Company sponsors a tax-qualified defined contribution employee profit
sharing and 401(k) plan (the "401(k) Plan"). The 401(k) Plan consists of
employee pre-tax contributions, Company matching contributions and Company
discretionary contributions, and contains provisions which are intended to
satisfy the tax qualification requirement of Section 401(a) of the Code. Each
employee may elect to defer up to 15% of such employee's compensation, subject
to a maximum of $10,000 in 1999. The Company makes matching contributions
equal to a specified percentage of each employee's contribution and may also
make discretionary contributions for any plan year. Employee, matching and
discretionary contributions and earnings are fully vested and nonforfeitable
at all times and are invested according to the direction of the employee.     
 
  The Company also sponsors a tax-qualified defined contribution employee
money purchase pension plan (the "Money Purchase Plan"). The Money Purchase
Plan contains provisions which are intended to satisfy the tax qualification
requirement of Section 401(a) of the Code. The Company makes an annual
contribution equal to 4% of employee compensation. Plan contributions and
earnings are fully vested and nonforfeitable after five full years of service
and are invested according to the direction of the employee.
 
Annual Bonus Plan
   
  Following the Offering, the Company intends to establish an annual bonus
plan pursuant to which all full-time management personnel, including executive
officers, will be eligible to receive a bonus for exceptional individual or
team performance. The Company will reserve the right not to award bonuses in
any year.     
 
                             CERTAIN TRANSACTIONS
 
Reorganization
   
  Trex Company, Inc. is currently a wholly-owned subsidiary of Trex Company,
LLC, a Delaware limited liability company. Prior to the consummation of the
Offering, the members of Trex Company, LLC other than Mobil will contribute
their membership interests in Trex Company, LLC to Trex Company, Inc. in
exchange for Common Stock of Trex Company, Inc. Concurrently with such
exchange, Trex Company, Inc. will purchase Mobil's membership interest in Trex
Company, LLC for $3.1 million payable upon consummation of the Offering. As a
result of the Exchange Transaction and such purchase, Trex Company, LLC will
become a wholly-owned subsidiary of Trex Company, Inc. In connection with the
Exchange Transaction, the Certificate of Incorporation and Bylaws will be
restated in their entirety. See "Description of Capital Stock" for a
description of the Certificate of Incorporation and Bylaws that will be in
effect at the time of the consummation of the Offering.     
   
  In the Exchange Transaction, the junior membership interests in Trex
Company, LLC will be exchanged for shares of Common Stock of Trex Company,
Inc. as follows: (i) the membership interests of the Management Holders (as
defined below) will be exchanged for a total of 9,225,000 shares of Common
Stock; and (ii) the membership interests of the Institutional Investors will
be exchanged for a total of 1,025,000 shares of Common Stock. The Company will
receive no additional consideration in connection with the exchange of
membership interests for shares of Common Stock. Immediately following the
Exchange Transaction, the Management Holders and the Institutional Investors
will beneficially own 90% and 10%, respectively, of the outstanding Common
Stock, which is the same proportion in which they held membership interests in
Trex Company, LLC immediately before the Exchange Transaction.     
 
 
                                      48
<PAGE>
 
   
  Before the Exchange Transaction, Trex Company, LLC will exercise an option
to repurchase from the Institutional Investors approximately 667 junior
membership interests designated as Class A Units. As a result of exercise of
this option, the beneficial ownership of outstanding junior membership
interests by the Institutional Investors will decrease to 10% from 25%, while
the beneficial ownership of outstanding junior membership interests by the
Management Holders will increase to 90% from 75%. The terms of this option are
set forth in an agreement which Trex Company, LLC, the Management Holders and
the Institutional Investors entered into in connection with the Acquisition.
The option exercise price will be $.01 for each junior membership interest
repurchased. The number of junior membership interests Trex Company, LLC may
repurchase pursuant to the option is based on the internal rate of return
earned since the Acquisition by the Institutional Investors on their
investment in Trex Company, LLC, which consists of the Senior Notes, the
Subordinated Notes and their junior membership interests. The initial public
offering price of the Shares is one component of the internal rate of return
calculation. The number of junior membership interests Trex Company, LLC will
repurchase will be the same at each of the initial public offering prices of
the Shares within the range set forth on the cover page of this Prospectus.
       
  In connection with the Exchange Transaction, Trex Company, LLC will make the
LLC Distribution to the Management Holders and the Institutional Investors.
The estimated amount of the LLC Distribution as of December 31, 1998 is $5.6
million. Such amount will be increased by the amount of any taxable income
realized by Trex Company, LLC from January 1, 1999 through the date of the LLC
Distribution. Of the LLC Distribution, which is estimated to be approximately
$9.3 million as of the expected payment date, approximately $6.9 million
represents the amount of the previously recognized and undistributed income of
Trex Company, LLC through the expected payment date on which the members have
paid, or will pay, income tax and approximately $2.4 million represents a
return of capital.     
       
          
  Trex Company, Inc. was organized in September 1998 under the laws of the
State of Delaware for the purpose of acquiring all of the membership interests
and operating the business of Trex Company, LLC. Trex Company, Inc. has not
conducted, and prior to the Exchange Transaction will not conduct, any
business other than in connection with the Offering and the other transactions
described herein.     
 
Acquisition Transactions
   
  Acquisition. In the Acquisition, the Company purchased the assets of Mobil's
Composite Products Division in a management-led buyout for a cash purchase
price of approximately $29.5 million. The Acquisition and the Company's
initial operations were financed by a combination of the following: (i)
proceeds of $29.3 million from the sale by the Company of $24.3 million
principal amount of Senior Notes, $5.0 million principal amount of
Subordinated Notes and a total of 1,000 Class B Units to Connecticut General
Life Insurance Company, Connecticut General Life Insurance Company on behalf
of one or more separate accounts and Life Insurance Company of North America;
(ii) proceeds of $3.0 million from the sale by the Company of 1,000 Preferred
Units (the "Preferred Units") to Mobil; and (iii) proceeds of $2.0 million
from the sale by the Company of 750 Class A Units to each of Robert G.
Matheny, Anthony J. Cavanna, Andrew U. Ferrari and Roger A. Wittenberg
(collectively, the "Management Holders"). The Institutional Investors will
convert their Class B Units to Class A Units prior to the Reorganization.     
 
  On June 25, 1997, the Company prepaid $3.0 million principal amount of
Senior Notes.
 
  In January 1998, Connecticut General Life Insurance Company transferred 333
Class B Units to Lincoln National Life Insurance Company in connection with
the sale of certain assets.
 
  As a result of the indebtedness incurred to finance the Acquisition, the
Company has been highly leveraged. The terms of the Company's financing
agreements have required substantial debt service
 
                                      49
<PAGE>
 
payments. Such financing agreements also have required the Company to comply
with various restrictive covenants, financial ratios and other financial and
operating tests.
 
  Acquisition-Related Agreements. The Company and its members entered into
certain agreements in connection with the Acquisition relating to the members'
interests in the Company or any successor entity.
   
  Pursuant to the Members' Agreement dated as of August 29, 1996 among the
Company, the Management Holders and the Institutional Investors (the "Members'
Agreement"), the Company has granted certain "demand" and "piggyback"
registration rights with respect to Common Stock issuable to the Institutional
Investors upon consummation of the Reorganization. The Institutional Investors
are entitled to require the Company to register the sale of their shares under
the Securities Act on up to two occasions. In addition, if the Company
proposes to register the Common Stock under the Securities Act (other than
pursuant to a registration statement on Form S-4 or Form S-8), whether or not
for its own account, the Institutional Investors are entitled to require the
Company, subject to certain conditions, to include all or a portion of their
shares in such registration. The foregoing registration rights are subject to
certain notice requirements, timing restrictions and volume limitations which
may be imposed by the underwriters of an offering. The Company is required to
bear the expenses of all such registrations except for underwriting discounts
and commissions.     
   
  Pursuant to the Limited Liability Company Agreement dated as of August 29,
1996 among the Management Holders, the Institutional Investors and Mobil, the
Institutional Investors were granted the right to approve certain actions by
the Company outside the ordinary course of its business, including the sale of
all or a substantial part of the Company's assets and the incurrence or
payment of specified types of indebtedness. This agreement will be terminated
following consummation of the Reorganization.     
   
  Pursuant to the Class A Members' Agreement dated as of August 29, 1996, the
Management Holders agreed to certain restrictions on the sale, transfer or
other disposition of their membership interests in the Company. This agreement
will be terminated following consummation of the Reorganization.     
   
  In connection with the Acquisition, each Management Holder entered into an
employment agreement with the Company. The employment agreements will be
terminated following consummation of the Offering.     
 
Other Transactions
   
  The Company paid the Institutional Investors interest on the Senior Notes
and Subordinated Notes of $1.0 million for 1996, $3.0 million for 1997 and
$2.7 million for 1998.     
   
  The Company paid Mobil dividends on the Preferred Units of $0.1 million for
1996, $0.4 million for 1997 and $0.4 million for 1998.     
 
  The Company will use a portion of the net proceeds of the Offering to repay
the Senior Notes and the Subordinated Notes and to purchase Mobil's preferred
equity interest in the Company issued in connection with the Acquisition. See
"Use of Proceeds."

                         DESCRIPTION OF CAPITAL STOCK
   
  The following summary description of the capital stock of the Company does
not purport to be complete and is subject to the provisions of the Certificate
of Incorporation and Bylaws, which will be in effect at the time of the
consummation of the Offering, and to the provisions of the applicable law. The
Certificate of Incorporation and the Bylaws are included as exhibits to the
Registration Statement of which this Prospectus forms a part.     
 
Authorized and Outstanding Capital Stock
   
  Upon consummation of the Reorganization, the Company will have authority to
issue 43,000,000 shares of capital stock, consisting of 40,000,000 shares of
Common Stock, par value $.01 per share, and 3,000,000 shares of Preferred
Stock, par value $.01 per share (the "Preferred Stock"). As of December 31,
1998, after giving effect to the Reorganization and the Offering, 13,500,000
shares of Common Stock (or 14,002,950 shares of Common Stock if the Over-
Allotment Option is exercised in full) will be issued and outstanding and no
shares of Preferred Stock will be issued and outstanding.     
 
Common Stock
 
  Holders of Common Stock are entitled to one vote per share for each share
held of record on all matters submitted to a vote of stockholders. Holders of
Common Stock are entitled to receive ratably such dividends as may be declared
by the Board of Directors on the Common Stock out of funds legally available
therefor. In the event of a liquidation, dissolution or winding up of the
affairs of the Company, holders of Common Stock are entitled to share ratably
in the assets available for distribution after payments to the creditors and
to the holders of any Preferred Stock that may be outstanding at such time.
Holders of Common Stock have no preemptive rights, cumulative voting rights or
rights to convert shares of Common Stock into any other securities, and are
not subject to future calls or assessments by the Company. All outstanding
shares of Common Stock of the Company are, and the Shares issued in the
Offering will be, fully paid and nonassessable.
 
Preferred Stock
   
  The Board of Directors is authorized without further stockholder action to
provide for the issuance from time to time of up to 3,000,000 shares of
Preferred Stock in one or more series with such powers, designations,
preferences and relative, participating, optional or other rights,
qualifications, limitations or restrictions as will be set forth in the
resolutions providing for the issuance of such series adopted by the Board of
Directors. The holders of Preferred Stock will have no preemptive rights
(unless otherwise provided in the applicable certificate of designation) and
will not be subject to future assessments by the Company. Such Preferred Stock
may have voting or other rights which could adversely affect the rights of
holders of the Common Stock. In addition, the issuance of Preferred Stock,
while providing the Company with financial flexibility in connection with
possible acquisitions and other corporate purposes, could, under certain
circumstances, make it more difficult for a third party to gain control of the
Company, discourage bids for the Common Stock at a premium, or otherwise
adversely affect the market price of the Common Stock. The Company currently
has no intention to issue any Preferred Stock.     
 
Anti-Takeover Effect of Certain Charter and Bylaw Provisions
 
  The Certificate of Incorporation and the Bylaws contain certain provisions
that could make it more difficult to consummate an acquisition of the Company
by means of a tender offer, a proxy contest or otherwise.
 
  Classified Board of Directors. The Certificate of Incorporation and the
Bylaws provide that the Board of Directors will be divided into three classes
of directors, with the classes to as nearly equal
 
                                      52
<PAGE>
 
   
in number as possible. As a result, approximately one-third of the Board of
Directors will be elected each year. The classification of the Board of
Directors will make it more difficult for an acquiror or for other
stockholders to change the composition of the Board of Directors. The
Certificate of Incorporation provides that, subject to any rights of holders
of Preferred Stock to elect additional directors under specified
circumstances, the total number of directors constituting the entire Board of
Directors will be not less than five directors nor more than 20 directors,
with the authorized number of directors being fixed from time to time by the
Board of Directors. In addition, the Certificate of Incorporation provides
that, subject to any rights of holders of Preferred Stock, and unless the
Board of Directors otherwise determines, any vacancies will be filled only by
the affirmative vote of a majority of the remaining directors, though less
than a quorum.     
   
  No Stockholder Action by Written Consent. The Certificate of Incorporation
and Bylaws provide that, subject to the rights of any holders of Preferred
Stock to act by written consent in lieu of a meeting, stockholder action may
be taken only at an annual meeting or special meeting of stockholders and may
not be taken by written consent in lieu of a meeting, unless the action to be
effected by written consent of stockholders and the taking of such action by
such written consent have expressly been approved in advance by the Board of
Directors. Failure to satisfy any of the requirements for a stockholder
meeting could delay, prevent or invalidate stockholder action.     
   
  Stockholder Advance Notice Procedure. The Bylaws establish an advance notice
procedure for stockholders to make nominations of candidates for election as
directors or to bring other business before an annual or special meeting of
stockholders of the Company (the "Stockholder Notice Procedure"). The
Stockholder Notice Procedure provides that only persons that are named in the
Company's notice of meeting or that are nominated by the Board of Directors or
by a stockholder who has given timely written notice to the Secretary of the
Company prior to the meeting at which directors are to be elected, will be
eligible for election as directors of the Company. Any such notice is required
to set forth, among other things, specified information about the stockholder,
the beneficial owner (if any) on whose behalf the nomination is made and each
proposed director nominee, such other information regarding each proposed
nominee as would be required to be included in a proxy statement filed
pursuant to the rules and regulations of the Securities and Exchange
Commission, the written consent of each proposed nominee to serve as a
director of the Company if elected, and a representation whether the
stockholder or the beneficial owner, if any, intends or is part of a group
which intends to solicit proxies in support of such nomination. The
Stockholder Notice Procedure also provides that only such business may be
conducted at an annual or special meeting as has been brought before the
meeting by, or at the direction of, the Board of Directors or by a stockholder
who has given timely written notice to the Secretary of the Company. Any such
notice is required to set forth, among other things, a brief description of
the business desired to be brought before the meeting, any material interest
of the stockholder in such business, and specified information about such
stockholder and such stockholder's ownership of capital stock of the Company.
    
Section 203 of the Delaware General Corporation Law
 
  The Company is subject to Section 203 ("Section 203") of the Delaware
General Corporation Law which, subject to certain exceptions, prohibits a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the time that
such stockholder became an interested stockholder unless: (i) prior to such
time, the board of directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an
interested stockholder; or (ii) upon consummation of the transaction which
resulted in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned (a) by persons
who are directors and also officers and (b) by employee stock plans in which
employee participants do not have the right to determine confidentially
whether shares
 
                                      53
<PAGE>
 
   
held subject to the plan will be tendered in a tender or exchange offer; or
(iii) at or subsequent to such time, the business combination is approved by
the board of directors and authorized at an annual or special meeting of
stockholders, and not by written consent, by the affirmative vote of at least
66 2/3% of the outstanding voting stock which is not owned by the interested
stockholder.     
 
  Section 203 defines "business combination" to include the following: (i) any
merger or consolidation of the corporation with the interested stockholder;
(ii) any sale, transfer, pledge or other disposition of 10% or more of the
assets of the corporation involving the interested stockholder; (iii) subject
to certain exceptions, any transaction that results in the issuance or
transfer by the corporation of any stock of the corporation to the interested
stockholder; (iv) any transaction involving the corporation that has the
effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder; or
(v) any receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or
through the corporation. In general, Section 203 defines an interested
stockholder as any entity or person beneficially owning 15% or more of the
outstanding voting stock of the corporation and any entity or person
affiliated with or controlling or controlled by such entity or person.
 
Director Liability and Indemnification of Directors and Officers
 
  The Delaware General Corporation Law provides that a corporation may limit
the liability of each director to the corporation or its stockholders for
monetary damages except for liability (i) for any breach of the director's
duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or that involve intentional misconduct or a
knowing violation of law, (iii) in respect of certain unlawful dividend
payments or stock redemptions or repurchases and (iv) for any transaction from
which the director derives an improper personal benefit. The Certificate of
Incorporation provides for the elimination and limitation of the personal
liability of directors of the Company for monetary damages to the fullest
extent permitted by the Delaware General Corporation Law. In addition, the
Certificate of Incorporation provides that if the Delaware General Corporation
Law is amended to authorize the further elimination or limitation of the
liability of a director, then the liability of the directors will be
eliminated or limited to the fullest extent permitted by the Delaware General
Corporation Law, as so amended. The effect of this provision is to eliminate
the rights of the Company and its stockholders (through stockholder derivative
suits on behalf of the Company) to recover monetary damages against a director
for breach of the fiduciary duty of care as a director (including breaches
resulting from negligent or grossly negligent behavior), except in situations
described in clauses (i) to (iv) above. The provision does not limit or
eliminate the rights of the Company or any stockholder to seek non-monetary
relief such as an injunction or rescission in the event of a breach of
director's duty of care. This provision is consistent with Section 102(b)(7)
of the Delaware General Corporation Law, which is designed, among other
things, to encourage qualified individuals to serve as directors of Delaware
corporations. The Company believes this provision will assist it in securing
and maintaining the services of qualified individuals who are not employees of
the Company.
 
  The Bylaws provide that the Company will, to the full extent permitted by
the Delaware General Corporation Law, as amended from time to time, indemnify,
and advance expenses to, each of its currently acting and former directors,
officers, employees and agents.

                        SHARES ELIGIBLE FOR FUTURE SALE
   
  Upon completion of the Offering, after giving effect to the Reorganization,
there will be 13,500,000 shares of Common Stock outstanding. The 3,353,000
Shares offered hereby, other than up to 162,500 Reserved Shares, will be
freely tradable upon completion of the Offering without restriction under the
Securities Act by persons other than "affiliates" of the Company as defined in
Rule 144 under the Securities Act. The remaining shares of Common Stock will
be deemed "restricted securities" within the meaning of Rule 144 and, as such,
will not be eligible for future sale to the public unless they are sold in
transactions under the Securities Act or pursuant to an exemption from
registration, including the exemption afforded by Rule 144.     
   
  The Company, all current stockholders of the Company and the holders of
Reserved Shares, have entered into "lock-up" agreements with the Underwriters
pursuant to which they have agreed that they will not, for a period of 180
days after the closing of the Offering, offer, sell, contract to sell, issue
or otherwise dispose of any shares of Common Stock or any securities of the
Company which are substantially similar to the Common Stock, or which are
convertible into or exchangeable or exercisable for Common Stock or securities
substantially similar to the Common Stock without the prior written consent of
Schroder & Co. Inc. Such consent may be granted in whole or in part without a
public announcement. Such agreements have been expressly agreed to preclude
such parties from engaging in any hedging or other transaction which is
designed to or reasonably could be expected to lead to or result in a sale or
disposition of securities during the applicable period, even if such
securities would be disposed of by someone other than such party. Such
prohibited hedging or other transactions would include, without limitation,
any short sale (whether or not against the box) or any purchase, sale or grant
of any right (including, without limitation, any put or call option) with
respect to any such securities or with respect to any security (other than a
broad-based market basket or index) that includes, relates to or derives any
significant part of its value from such securities. The foregoing restrictions
will not apply to the issuance of options to purchase Common Stock pursuant to
the Stock Incentive Plan or the Outside Director Plan, to transfers of Common
Stock to the Company or to certain transfers of Common Stock to family trusts
or by gift, will or intestate succession. As a condition to any such transfer
to a family trust or transfer by gift, will or intestate succession, the
transferee (or trustee or legal guardian on the transferee's behalf) will be
required to execute and deliver a lock-up agreement containing the terms
described in this paragraph. Upon expiration of the lock-up period, the
Reserved Shares will be freely tradable by persons other than affiliates of
the Company and up to 10,147,000 shares of Common Stock will be eligible for
sale under Rule 144.     
   
  In general, under Rule 144 as currently in effect, a stockholder (or
stockholders whose shares are aggregated), including an affiliate of the
Company, who has beneficially owned "restricted securities" for at least one
year is entitled to sell, within any three-month period, a number of such
shares that does not exceed the greater of (i) 1% of the then outstanding
shares of Common Stock (approximately 135,000 shares of Common Stock
immediately after the Offering) or (ii) the average weekly trading volume of
the Common Stock on the New York Stock Exchange during the four calendar weeks
preceding the filing of a notice on Form 144 with respect to such sale with
the Securities and Exchange Commission. Sales under Rule 144 also are subject
to certain other requirements regarding the manner of sale, notice and
availability of current public information about the Company. Under Rule
144(k), if a period of at least two years has elapsed between the later of the
date restricted securities were acquired from the Company and the date they
were acquired from an affiliate of the Company, a stockholder who is not an
affiliate of the Company at the time of sale and has not been an affiliate at
any time during the 90 days prior to the sale would be entitled to sell shares
of Common Stock immediately without compliance with the requirements under
Rule 144, other than the requirements as to the availability of current public
information about the Company. All current stockholders of the Company may be
deemed to be affiliates of the Company for purposes of Rule 144. The foregoing
summary of Rule 144 is not intended to be a complete description thereof.     
 
                                      55
<PAGE>
 
   
  The Company has granted "demand" and "piggyback" registration rights with
respect to the Common Stock held by the Institutional Investors. The
Institutional Investors are entitled to require the Company to register the
sale of their shares under the Securities Act on up to two occasions. In
addition, if the Company proposes to register the Common Stock under the
Securities Act (other than pursuant to a registration statement on Form S-4 or
Form S-8), whether or not for its own account, the Institutional Investors are
entitled to require the Company, subject to certain conditions, to include all
or a portion of their shares in such registration. The foregoing registration
rights are subject to certain notice requirements, timing restrictions and
volume limitations which may be imposed by the underwriters of an offering.
The Company is required to bear the expenses of all such registrations except
for underwriting discounts and commissions. Following the consummation of the
Offering, 922,000 shares of Common Stock, or 6.8% of the total number of
outstanding shares of Common Stock, will be entitled to the benefits of such
registration rights. See "Certain Transactions--Acquisition Transactions."
    
  Prior to the Offering, there has been no public market for the Common Stock.
Future sales of a substantial number of shares of Common Stock in the public
market, or the perception that such sales could occur, could adversely affect
the prevailing market price of the Common Stock and could make it more
difficult for the Company to raise funds through a public offering of its
equity securities.

  Under the terms and subject to the conditions set forth in an underwriting
agreement, dated          , 1999 (the "Underwriting Agreement"), the Company
and the Selling Stockholders have agreed to sell to each of the underwriters
named below (collectively, the "Underwriters"), and each of the Underwriters
has severally agreed to purchase from the Company and the Selling
Stockholders, the respective number of shares of Common Stock set forth
opposite its name below for aggregate gross proceeds to the Company of
$45,500,000 and to the Selling Stockholders of $1,442,000, payable in cash
against delivery of a certificate or certificates representing each share of

  The Underwriting Agreement provides that the Underwriters' obligation to pay
for and accept delivery of the Shares is subject to certain conditions
precedent and that the Underwriters will be obligated to purchase all such
Shares if any are purchased. Schroder & Co. Inc., as representative of the
Underwriters (the "Representative"), has informed the Company that no sales of
Shares will be confirmed to discretionary accounts.     
   
  The closing of the purchase and sale of the Shares is intended to occur on
or about         , 1999, or such other dates as may be agreed upon by the
Company and the Representative.     
 
  The Underwriters propose to offer the Shares in part directly to the public
at the initial public offering price set forth on the cover page of this
Prospectus and in part to certain securities dealers at a price that
represents a concession not in excess of $      per Share under the initial
public offering price. The Underwriters may allow, and such dealers may re-
allow, a concession not in excess of $       per Share on sales to certain
brokers and dealers. After the Shares are released for sale to the public, the
offering price and other selling terms may from time to time be varied by the
Underwriters.
   
  The Company has granted to the Underwriters the Over-Allotment Option,
exercisable for 30 days from the closing of the Offering, to purchase up to an
aggregate of 502,950 additional shares of Common Stock on the same terms and
conditions as apply to purchases of the Shares. To the extent such option is
exercised, each Underwriter will become obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number set out next to each such Underwriter's name in the table
above bears to the total number of shares of Common Stock offered by the
Underwriters hereunder. If the Over-Allotment Option is exercised in full, the
total price to public of the Shares will be $     , the total underwriting
discounts and commissions will be $      and the total net proceeds to the
Company will be $     , after deducting the Underwriters' discounts and
commissions but before estimated Offering expenses.     
 
  The obligations of the Underwriters under the Underwriting Agreement may be
terminated at the discretion of the respective Underwriters upon the
occurrence of certain events.
   
  The Company, all stockholders of the Company prior to the Offering and the
holders of Reserved Shares have entered into "lock-up" agreements with the
Underwriters pursuant to which they have agreed that, for a period of 180 days
after the closing of the Offering, subject to certain limited exceptions, they
will not offer, sell, contract to sell, issue or otherwise dispose of any
shares of Common Stock or any securities of the Company which are
substantially similar to the Common Stock, or which are convertible into or
exchangeable or exercisable for Common Stock or securities     
 
                                      57
<PAGE>
 
   
substantially similar to the Common Stock without the prior written consent of
Schroder & Co. Inc. Such consent may be granted in whole or in part without a
public announcement. Such agreements have been expressly agreed to preclude
such parties from engaging in any hedging or other transaction which is
designed to or reasonably could be expected to lead to or result in a sale or
disposition of such securities during the applicable period, even if such
securities would be disposed of by someone other than such party. Such
prohibited hedging or other transactions would include, without limitation,
any short sale (whether or not against the box) or any purchase, sale or grant
of any right (including, without limitation, any put or call option) with
respect to any such securities or with respect to any security (other than a
broad-based market basket or index) that includes, relates to or derives any
significant part of its value from such securities. See "Shares Eligible for
Future Sale."     
   
  At the request of the Company, up to 162,500 Shares have been reserved for
sale in the Offering to certain individuals, including directors and employees
of the Company, members of their families or friends, and other persons having
business relationships with the Company. The sale of the Reserved Shares to
such persons will be at the initial public offering price set forth on the
cover page of this Prospectus, less the underwriting discounts and
commissions. The number of Shares available for sale to the general public
will be reduced to the extent these persons purchase the Reserved Shares. Any
Reserved Shares not purchased will be offered by the Underwriters to the
general public on the same basis as the other Shares offered hereby.     
   
  The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities that the Underwriters may incur in
connection with the sale of the Shares, including liabilities arising under
the Securities Act, and to contribute to payments that the Underwriters may be
required to make with respect thereto.     
   
  Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price of the Shares will be determined by
negotiations among the Company, the Selling Stockholders and the
Representative. Among the factors to be considered in determining the initial
public offering price of the Shares, in addition to prevailing market
conditions, are the Company's historical performance, the Underwriters'
estimates of the business potential and earnings prospects of the Company, an
assessment of the Company's management and the consideration of the above
factors in relation to market valuation of companies in related businesses.

Exchange under the symbol "TWP" subject to notice of issuance.     
   
  In connection with the Offering, the Underwriters and their affiliates may
engage in transactions that stabilize, maintain or otherwise affect the market
price of the Shares. Such transactions may include stabilization transactions
effected in accordance with Rule 104 of Regulation M, pursuant to which such
persons may bid for or purchase Shares for the purpose of stabilizing their
market price. The Underwriters also may create a short position for their
accounts by selling more shares of Common Stock in connection with the
Offering than they are committed to purchase from the Company and the Selling
Stockholders, and in such case may purchase shares of Common Stock in the open
market following completion of the Offering to cover all or a portion of such
short position. In addition, the Representative, on behalf of the
Underwriters, may impose "penalty bids" under contractual arrangements with
the Underwriters whereby it may reclaim from a dealer participating in the
Offering, for the account of the Underwriters, the selling concession with
respect to Shares that are distributed in the Offering but subsequently
purchased for the account of the Underwriters in the open market. Any of the
transactions described in this paragraph may result in the maintenance of the
price of the Shares at a level above that which might otherwise prevail in the
open market. None of the transactions described in this paragraph is required,
and, if such transactions are undertaken, they may be discontinued at any
time.

Board of Directors
Trex Company, Inc.
   
We have audited the accompanying balance sheet of Trex Company, Inc. (the
"Company") as of December 31, 1998. The balance sheet is the responsibility of
the Company's management. Our responsibility is to express an opinion on the
balance sheet based on our audit.     
 
We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the balance sheet is free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the balance sheet. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall balance sheet
presentation. We believe that our audit provides a reasonable basis for our
opinion.
   
In our opinion, the balance sheet referred to above presents fairly, in all
material respects, the financial position of Trex Company, Inc. at December
31, 1998 in conformity with generally accepted accounting principles.

1. BUSINESS AND ORGANIZATION
   
  Trex Company, Inc. (the "Company"), a Delaware corporation, was incorporated
on September 4, 1998, for the purpose of acquiring 100% of the membership
interests and operating the business of Trex Company LLC, in conjunction with
a proposed initial public offering ("IPO") of the Company's Common Stock. The
Company is a wholly owned subsidiary of Trex Company, LLC. Prior to the
proposed IPO, the Company will amend its certificate of incorporation to
increase its authorized capital to 40,000,000 shares of Common Stock and
3,000,000 shares of Preferred Stock.     
   
  Prior to the Company's proposed IPO, the junior membership interests in Trex
Company, LLC will be exchanged for shares of Common Stock of the Company and
the preferred membership interests in Trex Company, LLC will be purchased by
the Company (the "Reorganization"). Subsequent to such transactions, Trex
Company, LLC will be a wholly owned subsidiary of the Company. In conjunction
with the Reorganization, Trex Company, LLC will (1) pay a cash distribution to
its members representing undistributed Trex Company, LLC taxable earnings and
a return of capital and (2) recognize a deferred income tax liability
resulting from the conversion of Trex Company, LLC to a C corporation.     
   
  The net proceeds from the proposed IPO are planned to be used primarily to
reduce outstanding indebtedness, fund a portion of the cash distribution to
its members, purchase all outstanding preferred equity and provide funds for
expansion of operations, working capital needs and other general corporate
purposes.     
   
  The Company has had no operations or activity since inception on September
4, 1998 through December 31, 1998.     
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Cash And Cash Equivalents
 
  Cash equivalents consist of highly liquid investments purchased with
original maturities of three months or less.
 
Income Taxes
 
  Income taxes are accounted for using the liability method required by
Statement of Financial Accounting Standards (SFAS) No. 109, "Accounting for
Income Taxes."
 
Fair Value Of Financial Statements
   
  The Company considers the recorded value of its financial assets consisting
of cash and cash equivalents to approximate the fair value of the respective
assets at December 31, 1998.

                        REPORT OF INDEPENDENT AUDITORS
 
Board of Managers
Trex Company, LLC
 
We have audited the accompanying balance sheets of Trex Company, LLC (the
"Company") as of December 31, 1997 and 1998, and the related statements of
operations, members' equity, and cash flows for the period from July 1, 1996
(Inception) to December 31, 1996 and for the years ended December 31, 1997 and
1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements 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 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 financial statements referred to above present fairly, in
all material respects, the financial position of Trex Company, LLC at December
31, 1997 and 1998, and the results of its operations and its cash flows for
the period from July 1, 1996 (Inception) to December 31, 1996 and for the
years ended December 31, 1997 and 1998 in conformity with generally accepted

                         Notes to Financial Statements
 
 For the period from July 1, 1996 (Inception) to December 31, 1996 and for the
                    years ended December 31, 1997 and 1998
 
1. BUSINESS AND ORGANIZATION
 
Trex Company, LLC ("Trex" or the "Company") manufactures and distributes wood
polymer (thermo-plastic) composite products primarily for consumer and
commercial decking applications. Trex lumber is manufactured primarily from
reclaimed plastic (mainly shopping bags and stretch film) and hardwood waste.
 
Organization
 
Trex is a limited liability company formed under the laws of the State of
Delaware on July 1, 1996 (Inception). The Company initiated commercial
activity on August 29, 1996.
 
On August 29, 1996, Trex acquired substantially all of the assets and assumed
certain liabilities of Mobil Corporation's Composite Products Division
("CPD"). The Company acquired these net assets for cash of approximately $29
million. The acquisition was accounted for using the purchase accounting
method.
   
Reorganization     
   
On September 4, 1998 the Company formed a wholly owned subsidiary, Trex
Company, Inc., for the purpose of acquiring 100% of the membership interests
and operating the business of the Company in conjunction with the subsidiary's
proposed initial public offering of common stock (the "IPO"). The Company will
account for the reorganization as an exchange of shares between entities under
common control at historical cost in a manner similar to a pooling of
interests. As of December 31, 1998, the Company had capitalized its subsidiary
with an initial capital contribution of $1,000 and the subsidiary had no other
assets or operations as of that date or for the inception period then ended.
The Company has reflected its investment in its subsidiary as a component of
other assets as of December 31, 1998.     
   
In connection with the anticipated IPO, which is expected to be consummated in
the first quarter of 1999, the Company will complete certain transactions
related thereto prior to the consummation of the IPO. See Note 12 for details
of these transactions.     
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Cash and Cash Equivalents
 
Cash equivalents consist of highly liquid investments purchased with original
maturities of three months or less.
 
Inventories
 
Inventories are stated at the lower of cost (last-in, first-out) or market
value.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
 
Long Lived Assets
 
  Property, Plant and Equipment
     
  Property, plant and equipment are stated at historical cost. The costs of
  additions and improvements are capitalized, while maintenance and repairs
  are expensed as incurred. Depreciation is provided using the straight line
  method over the following estimated useful lives:     
 
<TABLE>
      <S>                                                               <C>
      Machinery and equipment.......................................... 11 years
      Furniture and equipment.......................................... 10 years
      Forklifts and tractors...........................................  5 years
      Data processing equipment........................................  5 years
</TABLE>
 
  Leasehold improvements are amortized over the shorter of the lease term or
  the estimated useful life of the asset.
 
  Intangible Assets
 
  Intangible assets consist of goodwill representing the excess of cost over
  net assets acquired and organizational costs resulting from the purchase of
  CPD. Goodwill and organizational costs are amortized using the straight
  line method over periods of 15 and 5 years, respectively.
 
 The Company assesses the impairment of long-lived assets including intangible
assets in accordance with Statement of Financial Accounting Standards No. 121,
Accounting for the Impairment of Long Lived Assets and for Long Lived Assets
to be Disposed of ("SFAS 121"). SFAS 121 requires impairment losses to be
recognized for long-lived assets when indicators of impairment are present and
the undiscounted cash flows are not sufficient to recover the assets' carrying
amounts. Intangibles are also evaluated for recoverability by estimating the
projected undiscounted cash flows, excluding interest, of the related business
activities. The impairment loss of these assets, including goodwill, is
measured by comparing the carrying amount of the asset to its fair value with
any excess of carrying value over fair value written off. Fair value is based
on market prices where available, an estimate of market value, or various
valuation techniques including discounted cash flow.
 
Revenue Recognition
 
The Company recognizes revenue at the point of sale, which is at the time of
shipment to the customer from the warehouse.
 
Deferred Financing Charges
 
Deferred financing charges represent the unamortized portion of the discount
upon the issuance of the subordinated and senior notes (See Note 5). These are
amortized as interest expense using the effective interest method.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
 
Income Taxes
 
The Company is a partnership for income tax purposes. Accordingly, no
provision for income taxes has been included in these financial statements, as
taxable income or loss passes through to, and is reported by, members
individually.
 
Research and Development Costs
 
Research and development costs are expensed as incurred. For the period from
July 1, 1996 (Inception) to December 31, 1996 and for the years ended December
31, 1997 and 1998, research and development costs were approximately $357,000,
$909,000 and $946,000, respectively.
 
Advertising Costs
 
Advertising costs are expensed as incurred. For the period from July 1, 1996
(Inception) to December 31, 1996 and for the years ended December 31, 1997 and
1998, advertising costs were approximately $461,000, $2,103,000 and
$3,168,000, respectively.
 
Use of Estimates
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the amounts reported in the financial statements and the
accompanying notes. Actual results could differ from those estimates.
 
Fair Value of Financial Statements
 
The Company considers the recorded value of its financial assets and
liabilities, consisting primarily of cash and cash equivalents, accounts
receivable, accounts payable, accrued liabilities and other current
liabilities, and long term debt to approximate the fair value of the
respective assets and liabilities at December 31, 1997 and 1998.
 
Recent Pronouncements
 
The Company has determined that no recent FASB accounting pronouncements will
have a material impact on the Company's financial position or results of
operations.

Amortization expense for the period from July 1, 1996 (Inception) to December

$834,000 and $834,000, respectively.
 
6. DEBT
   
The Company maintains an agreement with a bank to provide a $6,000,000 line of
credit for working capital purposes, secured by substantially all of the
Company's accounts receivable and inventories. The line of credit accrues
interest at LIBOR plus 200 basis points and matures on April 10, 1999. There
were no amounts outstanding at December 31, 1997 or 1998.     
   
During the year ended December 31, 1998, the Company borrowed $4,815,000 under
two mortgages to fund, in part, the acquisition of a new manufacturing
facility and research development facility. The mortgages provide for monthly
amortization of principal and interest over a 15-year amortization schedule,
with all remaining principal due ten years from the mortgage dates. The
mortgages have floating rates of LIBOR plus 100 basis points, and the Company
entered into interest rate swap agreements, as discussed below, at the
notional amounts of the amortizing principal balances, that effectively fix
the interest rates paid by the Company at 7.12% and 6.80%, respectively.
During the year ended December 31, 1998, the Company borrowed $2,071,000 under
a promissory note. The note bears interest at 7.5%, payable monthly, with the
entire principal amount due September 5, 1999.

The Senior and Subordinated Notes are secured by substantially all of the
assets of the Company, with the Senior Notes holding liquidation preferences,
and are held by the Company's Class B Members. The mortgages and promissory
notes are secured by the Company's various real estate holdings and are held
by various financial institutions.
 
The Company made interest payments in the amount of approximately $1,025,000,
$2,975,000 and $2,875,000 for the period from July 1, 1996 (Inception) to
December 31, 1996 and for the years ended December 31, 1997 and 1998,
respectively.
 
During 1998, the Company entered into interest-rate swap agreements to
eliminate the impact of increases and decreases in interest rates on its
floating-rate mortgages. At December 31, 1998, the Company had two interest-
rate swap agreements outstanding. The agreements effectively entitle the
Company to receive from (pay to) the bank the amount, if any, by which the
Company's interest payments on its $3,780,000 and $1,035,000 floating-rate
mortgages due in June 2008 and November 2008 exceed (fall below) 7.12 and 6.80
percent, respectively. The Company has not incurred a premium or other fee for
these interest-rate swap agreements. Payments received (made) as a result of
the agreements are accrued as a reduction of (increase to) interest expense on
the floating-rate mortgage debt. The notional amounts of these agreements
correspond to the outstanding balances of the mortgage debt.
 
The Company is exposed to credit loss in the event of nonperformance by the
counter-party on interest-rate swap agreements but the Company does not
anticipate nonperformance by the counter-party. The amount of such exposure is
generally the unrealized gains in such agreements.

7. MEMBERS' EQUITY
 
Trex was initially capitalized by the sale of 3,000 Class A units for
$2,000,000 and 1,000 Class B units for $350,000. The Class A and Class B units
are collectively known as Junior units. In conjunction with the acquisition of
substantially all of the assets and assumption of certain liabilities of CPD,
the Company issued CPD 1,000 Preferred units in exchange for $3,000,000.
 
Class A members have the right to elect the members of the Company's Board of
Managers, which carries on the day-to-day business of the Company. Major
decisions of the Company, such as those outside the ordinary course of
business, require the approval of both Class A and Class B members. Class B
units are convertible pro-rata into Class A units.
 
The Preferred units are non-transferable and have limited voting rights as
defined in the Limited Liability Company Agreement. Preferred units are
entitled to a preferred annual return, which is cumulative and payable under
the terms of the Limited Liability Company Agreement. The Company has the
right to redeem the Preferred units upon 30 days prior notice at the original
issuance costs plus any accumulated preferred returns at the time of
redemption.
 
Cash distributions to members shall be distributed upon approval of the Board
of Managers and are limited under the terms of the Limited Liability Company
Agreement. Members' liabilities are limited to their respective capital
contributions.
 
The Company maintains a unitholders agreement that provides for certain
additional rights such as registration, approval of certain transactions and
other rights as defined in the agreement.
 
8. LEASES
   
The Company leases office space, storage warehouses and certain office and
plant equipment under various operating leases. Minimum annual payments under
these non-cancelable leases as of December 31, 1998 were as follows :

</TABLE>
 
For the period from July 1, 1996 (Inception) to December 31, 1996 and for the
years ended December 31, 1997 and 1998, the Company had rental expenses of
approximately $257,000, $1,020,000 and $1,024,000, respectively, including the
rental of the Company's plant which was purchased during 1998.

9. FRINGE BENEFIT PLANS
 
The Company has a 401(k) Profit Sharing Plan and a Money Purchase Pension Plan
for the benefit of all employees who meet certain eligibility requirements.
The plan documents provide for the Company to make defined contributions as
well as matching and other discretionary contributions, as determined by the
Board of Managers. The Company contributed $15,000, $85,000 and $120,000 to
the 401(k) Profit Sharing Plan and $0, $50,000 and $192,000 to the Money
Purchase Pension Plan during the period from July 1, 1996 (Inception) to
December 31, 1996 and for the years ended December 31, 1997 and 1998,
respectively.
 
10. OTHER INFORMATION
 
The Company is from time to time party to litigation arising in the ordinary
course of its business. The Company believes that such litigation will not
have a material impact on the Company's financial position or results from
operations.
 
During 1998, the Company entered into a take-or-pay contract to secure an
ongoing source of raw materials at competitive, market prices. The contract
requires the Company to take or pay for raw materials in the amount of
$3,300,000 annually for a period of nine years, commencing upon the counter-
party's completion of its production facility. No raw materials have been
supplied under this agreement.
   
Approximately 66%, 68% and 74% of the Company's sales for the period from July
1, 1996 (Inception) to December 31, 1996 and for the years ended December 31,
1997 and 1998, respectively, were from its five largest customers.
Approximately 25%, 24% and 22% of the Company's raw materials for the period
from July 1, 1996 (Inception) to December 31, 1996 and for the years ended
December 31, 1997 and 1998, respectively, were purchased from four suppliers.
    
11. PRO FORMA DATA (Unaudited)
   
The unaudited pro forma balance sheet gives effect to the reorganization (see
Notes 1 and 12) as if the reorganization had occurred on December 31, 1998 and
reflects (i) the repurchase of the Preferred units for approximately
$3,000,000 plus accrued dividends thereon of approximately $101,000, (ii) the
distribution of previously taxed earnings of the Company of approximately
$3,294,000 and a return of capital totaling $2,350,000, and (iii) the issuance
of 10,250,000 shares of Trex Company, Inc. common stock in exchange for the
Junior units in the Company. The unaudited pro forma balance sheet excludes
the effects of (i) the recognition of a net deferred tax liability totaling
approximately $2,400,000 that would have been recognized if the conversion
from a limited liability company to a corporation taxed in accordance with
Subchapter C of the Internal Revenue Code (a "C corporation") had occurred on
December 31, 1998, and (ii) certain transactions which will occur upon
consummation of the IPO (see Note 12).     
   
The pro forma statement of operations data give effect to the reorganization
as if the reorganization had occurred on January 1, 1998. The pro forma net
income taxes and pro forma net income reflect federal and state income taxes
(assuming a 40% combined effective tax rate) as if the Company had been taxed
as a C corporation for the year ended December 31, 1998. Pro forma weighted
average shares outstanding reflect 10,250,000 shares outstanding, which
assumes that the shares resulting from the reorganization were outstanding for
the year ended December 31, 1998 (See Note 12). Fully diluted income per share
is the same as basic income per share, and, therefore, is not separately
presented.

12. SUBSEQUENT EVENTS
          
The Company will complete certain transactions prior to the consummation of
the IPO by its wholly owned subsidiary at December 31, 1998, Trex Company,
Inc. Prior to the IPO, the Junior unitholders of the Company will contribute
their membership interests in the Company to Trex Company, Inc. in exchange
for common stock of Trex Company, Inc. (the "Exchange Transaction").
Concurrently with the Exchange Transaction, Trex Company, Inc. will purchase
the Preferred unitholder's interest in the Company for approximately
$3,101,000. As a result of the Exchange Transaction and such purchase, the
Company will become a wholly owned subsidiary of Trex Company, Inc. The
Company will account for the reorganization as an exchange of shares between
entities under common control at historical cost in a manner similar to a
pooling of interests. After the reorganization, the ownership percentage of
each Trex Company, Inc. common stockholder will be the same as its ownership
percentage in the Junior units of the Company.     
   
In connection with the Exchange Transaction, the Company will make a special
cash distribution to its Junior unitholders. If it had been made as of
December 31, 1998, the distribution would have totaled approximately
$5,644,000 and consisted of approximately $3,294,000 attributable to
previously recognized and undistributed income of the Company and
approximately $2,350,000 attributable to a return of capital at December 31,
1998. The actual distribution is subject to change based on the actual taxable
income of the Company during 1999 through the date of the Exchange
Transaction. In addition, a deferred income tax liability, estimated to be
approximately $2,357,000 at December 31, 1998, will be recognized as a result
of the conversion from a limited liability company to a C corporation.     
   
Immediately prior to the Exchange Transaction, the Company will exercise an
option to repurchase approximately 667 Junior units from certain unitholders
at a price of $.01 per unit. The terms of this option are set forth in an
agreement which the Company and the Junior unitholders entered into in
connection with the CPD acquisition. The Company's equity has not been
retroactively restated for the proposed reorganization.     
 
The net proceeds from the proposed IPO are planned to be used primarily to
reduce outstanding indebtedness, fund a portion of the LLC distributions,
redeem all outstanding preferred equity and provide funds for expansion of
operations, working capital needs, and other general corporate purposes.

                     MOBIL COMPOSITE PRODUCTS DIVISION OF
                    MOBIL OIL CORPORATION (THE PREDECESSOR)
 
                         Notes to Financial Statements
 
           For the year ended December 31, 1995 and the period from

1. BUSINESS AND ORGANIZATION
 
Mobil Composite Products Division, ("the Predecessor" or the "Division")
manufactures and distributes wood polymer (thermo-plastic) composite products
primarily for consumer and commercial decking applications. The Division is
operated by Mobil Chemical Company, a subsidiary of Mobil Oil Corporation
("the Parent"). The Division markets its products throughout North America.
 
On August 29, 1996, Trex Company, LLC ("Trex") acquired substantially all of
the assets and assumed certain of the liabilities of the Division. Trex
acquired these net assets for cash of approximately $29 million.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Inventories are stated at the lower of cost (last-in, first-out) or market
value.
 
Property, Plant and Equipment
 
Property, plant and equipment are stated at historical cost. The costs of
additions and improvements are capitalized, while maintenance and repairs are
charged to expense as incurred.

     Machinery and equipment............................... 11 years
     Furniture and equipment............................... 10 years
     Forklifts and tractors................................. 5 years
     Data processing equipment.............................. 5 years

                     MOBIL COMPOSITE PRODUCTS DIVISION OF
                    MOBIL OIL CORPORATION (THE PREDECESSOR)
 
                  Notes to Financial Statements--(continued)
 
 
Revenue Recognition
 
The Division recognizes revenue at the point of sale, which is at time of
shipment to the customer from the warehouse.
 
Research and Development Costs
 
Research and development costs are expensed as incurred. For the year ended
December 31, 1995 and the period from January 1, 1996 to August 28, 1996,
research and development costs were approximately $830,000 and $710,000,
respectively. Approximately $204,000 of these costs were allocated from
another division of the Parent for the year ended December 31, 1995, while
substantially all research and development costs were incurred directly by the
Division for the period from January 1, 1996 to August 28, 1996.
 
Advertising Costs
 
Advertising costs are expensed as incurred. For the year ended December 31,
1995 and the period from January 1, 1996 to August 28, 1996, advertising costs
were approximately $1,240,000 and $1,542,000, respectively.
 
Income Taxes
 
Income taxes have been excluded from the accompanying financial statements as
the Division was included in the consolidated tax returns of it Parent. There
were no tax allocations to the division during the year ended December 31,
1995 and the period from January 1, 1996 to August 28, 1996.
 
Use of Estimates
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the amounts reported in the financial statements and the
accompanying notes. Actual results could differ from those estimates.
 
3. LEASES
 
For the year ended December 31, 1995 and the period from January 1, 1996 to
August 28, 1996, the Division had rental expense of approximately $684,000 and
$451,000, respectively.
 
4. ALLOCATION OF EXPENSES
 
The Parent and certain of its subsidiaries provide the Division with various
administrative and financial services. These services include treasury,
insurance and tax administration, legal, certain payroll and employee benefit
administration, health and safety and environmental compliance. Mobil's policy
is to allocate centrally incurred costs primarily on the basis of usage or on
estimated time spent. Management believes these allocations and charges have
been made on a reasonable basis; however, they are not necessarily indicative
of the level of expenses which might have been incurred had the division been
operated as a stand-alone entity.

                  Notes to Financial Statements--(continued)
 
 
5. LITIGATION
 
During 1995 the Division incurred approximately $600,000 in legal expenses in
connection with a patent dispute. The dispute has been resolved in favor of
the Division. In addition, the Division is from time to time party to
litigation arising in the ordinary course of its business. The Division is not
subject to any material pending litigation.
 
6. PRO FORMA TAX PROVISION (UNAUDITED)
 
The pro forma unaudited condensed information is based upon the historical
financial information of the Division adjusted to reflect estimated income tax
provisions (assuming a 40% effective rate) on historical income before taxes
which would have occurred had the Division been taxed as a stand-alone entity.

Item 14. Indemnification of Directors and Officers
 
  Delaware General Corporation Law. Section 145(a) of the Delaware General
Corporation Law provides that a corporation may indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of
the corporation) by reason of the fact that the person is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by the person in
connection with such action, suit or proceeding if the person acted in good
faith and in a manner the person reasonably believed to be in or not opposed
to the best interests of the corporation, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe the person's conduct
was unlawful. The termination of any action, suit or proceeding by judgment,
order, settlement, conviction or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which the person reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect
to any criminal action or proceeding, had reasonable cause to believe that the
person's conduct was unlawful.
 
  Section 145(b) of the Delaware General Corporation Law states that a
corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or
in the right of the corporation to procure a judgment in its favor by reason
of the fact that the person is or was a director, officer, employee or agent
of the corporation, or is or was serving at the request of the corporation as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against expenses (including
attorneys' fees) actually and reasonably incurred by the person in connection
with the defense or settlement of such action or suit if the person acted in
good faith and in a manner the person reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which the person
 
 
                                     II-1
<PAGE>
 
shall have been adjudged to be liable to the corporation unless and only to
the extent that the Delaware Court of Chancery or the court in which such
action or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case,
the person is fairly and reasonably entitled to indemnity for such expenses
which the Delaware Court of Chancery or such other court shall deem proper.
 
  Section 145(c) of the Delaware General Corporation Law provides that to the
extent that a present or former director or officer of a corporation has been
successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in subsections (a) and (b) of Section 145, or in
defense of any claim, issue or matter therein, the person shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by the person in connection therewith.
 
  Section 145(d) of the Delaware General Corporation Law states that any
indemnification under subsections (a) and (b) of Section 145 (unless ordered
by a court) shall be made by the corporation only as authorized in the
specific case upon a determination that indemnification of the present or
former director, officer, employee or agent is proper in the circumstances
because the person has met the applicable standard of conduct set forth in
subsections (a) and (b) of Section 145. Such determination shall be made with
respect to a person who is a director or officer at the time of such
determination (i) by a majority vote of the directors who are not parties to
such action, suit or proceeding, even though less than a quorum, (ii) by a
committee of such directors designated by majority vote of such directors,
even though less than a quorum, or (iii) if there are no such directors, or if
such directors so direct, by independent legal counsel in a written opinion,
or (iv) by the stockholders.
 
  Section 145(f) of the Delaware General Corporation Law states that the
indemnification and advancement of expenses provided by, or granted pursuant
to, the other subsections of Section 145 shall not be deemed exclusive of any
other rights to which those seeking indemnification or advancement of expenses
may be entitled under any bylaw, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in such person's
official capacity and as to action in another capacity while holding such
office.
 
  Section 145(g) of the Delaware General Corporation Law provides that a
corporation shall have the power to purchase and maintain insurance on behalf
of any person who is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against any liability asserted
against such person and incurred by such person in any such capacity or
arising out of such person's status as such, whether or not the corporation
would have the power to indemnify such person against such liability under the
provisions of Section 145.
 
  Section 145(j) of the Delaware General Corporation Law states that the
indemnification and advancement of expenses provided by, or granted pursuant
to, Section 145 shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.
   
  Certificate of Incorporation. Article XI of the Certificate of Incorporation
provides that, to the fullest extent permitted by the Delaware General
Corporation Law, the Company's directors will not be personally liable to the
registrant or its stockholders for monetary damages resulting from a breach of
their fiduciary duties as directors. However, nothing contained in such
Article XII will eliminate or limit the liability of directors (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of the law, (iii) under Section 174 of the
Delaware General Corporation Law or (iv) for any transaction from which the
director derived an improper personal benefit.     
 
                                     II-2
<PAGE>
 
  Bylaws. The Bylaws provide for the indemnification of the officers and
directors of the Company to the fullest extent permitted by the Delaware
General Corporation Law. Article XII of the Bylaws provides that each person
who was or is made a party to (or is threatened to be made a party to) any
civil or criminal action, suit or proceeding by reason of the fact that such
person is or was a director or officer of the Company shall be indemnified and
held harmless by the Company to the fullest extent authorized by the Delaware
General Corporation Law against all expenses, liability and loss (including,
without limitation, attorneys' fees) incurred by such person in connection
therewith, if such person acted in good faith and in a manner such person
reasonably believed to be or not opposed to the best interests of the Company
and had no reason to believe that such person's conduct was illegal.
 
  Insurance. The directors and officers of the Company are covered by
insurance policies indemnifying against certain liabilities, including certain
liabilities arising under the Securities Act, which might be incurred by them
in such capacities and against which they cannot be indemnified by the
Company.
 
  Underwriting Agreement. The Underwriting Agreement will provide for the
indemnification against certain liabilities of the directors and officers of
the Company and certain controlling persons under certain circumstances,
including certain liabilities under the Securities Act.

Item 17. Undertakings
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities, the
  information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of Prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

     Section B. Rights of Preferred Stock.
                -------------------------

     1.  After the provisions with respect to preferential dividends on any
series of Preferred Stock (fixed in accordance with the provisions of Section
(A) of this Article VI), if any, shall have been satisfied and after the
Corporation shall have complied with all the requirements, if any, with respect
to redemption of, or the setting aside of sums as sinking funds or redemption or
purchase accounts with respect to, any series of Preferred Stock (fixed in
accordance with the provisions of Section (A) of this Article VI), and subject
further to any other conditions that may be fixed in accordance with the
provisions of Section (A) of this Article VI, then and not otherwise the holders
of Common Stock shall be entitled to receive such dividends as may be declared
from time to time by the Board.

     2.  In the event of the voluntary or involuntary liquidation, dissolution
or winding-up of the Corporation, after distribution in full of the preferential
amounts, if any (fixed in accordance with the provisions of Section (A) of this
Article VI), to be distributed to the holders of Preferred Stock by reason
thereof, the holders of Common Stock shall, subject to the additional rights, if
any (fixed in accordance with the provisions of Section (A) of this Article VI),
of the holders of any outstanding shares of Preferred Stock, be entitled to
receive all of the remaining assets of the Corporation, tangible or intangible,
of whatever kind available for distribution to stockholders ratably in
proportion to the number of shares of Common Stock held by them respectively.

     3.  Except as may otherwise be required by law, and subject to the
provisions of such resolution or resolutions as may be adopted by the Board
pursuant to Section (A) of this Article VI granting the holders of one or more
series of Preferred Stock exclusive voting powers with respect to any matter,
each holder of Common Stock may have one vote in respect to each share of Common
Stock held on all matters voted upon by the stockholders.

     4.  The number of authorized shares of Preferred Stock and each class of
Common Stock may, without a class or series vote, be increased or decreased from
time to time by the affirmative vote of the holders of shares having a majority
of the total number of votes which may be cast in the election of directors of
the Corporation by all stockholders entitled to vote in such an election, voting
together as a single class.

                                   ARTICLE VII

                                  ARTICLE VIII
                              ELECTION OF DIRECTORS

     The directors of the Corporation shall not be required to be elected by
written ballots unless the By-laws of the Corporation so provide.


                                   ARTICLE IX
                               BOARD OF DIRECTORS

     Section A. Classified Board. The Board, other than those directors elected
                ----------------
by the holders of any series of Preferred Stock as provided for or fixed
pursuant to the provisions of Article VI hereof, shall be divided into three
classes, as nearly equal in number as the then-authorized number of directors
constituting the Board permits, with the term of office of one class expiring
each year and with each director serving for a term ending at the third annual
meeting of stockholders of the Corporation following the annual meeting at which
such director was elected. One class of directors shall be initially elected for
a term expiring at the annual meeting of stockholders to be held in the year
2000, another class shall be initially elected for a term expiring at the annual
meeting of stockholders to be held in the year 2001, and another class shall be
initially elected for a term expiring at the annual meeting of stockholders to
be held in the year 2002. Members of each class shall hold office until their
successors are elected and qualified. At each succeeding annual meeting of the
stockholders of the Corporation, the successors of the class of directors whose
term expires at that meeting shall be elected by a plurality vote of all votes
cast at such meeting to hold office for a term expiring at the annual meeting of
stockholders held in the third year following the year of their election.

     Section B. Vacancies. Except as otherwise provided for or fixed pursuant to
                ---------  
the provisions of Article VI hereof relating to the rights of the holders of any
series of Preferred Stock to elect additional directors, newly created
directorships resulting from any increase in the authorized number of directors
and any vacancies on the Board resulting from death, resignation,
disqualification, removal or other cause shall be filled only by the affirmative
vote of a majority of the remaining directors then in office, even though less
than a quorum of the Board. Any director elected in accordance with the
preceding sentence shall hold office for the remainder of the full term of the
class of directors in which the new directorship was created or in which the
vacancy occurred and until such director's successor shall have been duly
elected and qualified. No decrease in the number of directors constituting the
Board shall shorten the term of any incumbent director.

     Section C. Directors Elected by Holders of Preferred Stock. During any
                -----------------------------------------------    
period when the holders of any series of Preferred Stock have the right to elect
additional directors as provided for or fixed pursuant to the provisions of
Article VI hereof, then upon commencement and for the duration of the period
during which 

                                       5
<PAGE>
 
such right continues (i) the then otherwise total authorized number of directors
of the Corporation shall automatically be increased by such specified number of
directors, and the holders of such Preferred Stock shall be entitled to elect
the additional directors so provided for or fixed pursuant to such provisions,
and (ii) each such additional director shall serve until such director's
successor shall have been duly elected and qualified, or until such director's
right to hold such office terminates pursuant to such provisions, whichever
occurs earlier. Except as otherwise provided by the Board in the resolution or
resolutions establishing such series, whenever the holders of any series of
Preferred Stock having such right to elect additional directors are divested of
such right pursuant to the provisions of such stock, the terms of office of all
such additional directors elected by the holders of such stock, or elected to
fill any vacancies resulting from death, resignation, disqualification or
removal of such additional directors, shall forthwith terminate and the total
and authorized number of directors of the Corporation shall be reduced
accordingly. Notwithstanding the foregoing, whenever, pursuant to the provisions
of Article VI hereof, the holders of any one or more series of Preferred Stock
shall have the right, voting separately as a series or together with holders of
other such series, to elect directors at an annual or special meeting of
stockholders, the election, term of office, filling of vacancies and other
features of such directorships shall be governed by the terms of this Restated
Certificate of Incorporation and the Certificate of Designation applicable
thereto, and such directors so elected shall not be divided into classes
pursuant to this Article IX unless expressly provided by such terms.

     Section D. Number of Directors Constituting the Board. Except as otherwise
                ------------------------------------------
provided for or fixed pursuant to Article VI hereof relating to the rights of
the holders of any series of Preferred Stock to elect additional directors, the
total number of directors constituting the entire Board shall be not less than
five (5) nor more than twenty (20), with the then-authorized number of directors
being fixed from time to time by the Board.

                                    ARTICLE X
                  NO ACTION BY WRITTEN CONSENT OF STOCKHOLDERS

     Except as otherwise provided for or fixed pursuant to the provisions of
Article VI hereof relating to the rights of the holders of any series of
Preferred Stock, no action that is required or permitted to be taken by the
stockholders of the Corporation at any annual or special meeting of stockholders
may be effected by written consent of stockholders in lieu of a meeting of
stockholders, unless the action to be effected by written consent of
stockholders and the taking of such action by such written consent have
expressly been approved in advance by the Board.

                                   ARTICLE XI
                               DIRECTOR LIABILITY

     A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the General Corporation Law or (iv)
for any transaction from which the director derived any improper personal

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

proposal of business to be considered by the stockholders may be made at an
annual meeting of stockholders only (i) pursuant to the Corporation's notice of
meeting (or any supplement thereto), (ii) by or at the direction of the Board of
Directors or (iii) by any stockholder of the Corporation who was a stockholder
of record of the Corporation at the time the notice provided for in this Section
10 is delivered to the Secretary of the Corporation, who is entitled to vote at

annual meeting by a stockholder pursuant to clause (ii) of paragraph (a) of this
Section 10, the stockholder must have given timely notice thereof in writing to
the Secretary of the Corporation, and such other business must otherwise be a
proper matter for stockholder action. To be timely, a stockholder's notice shall
be delivered to the Secretary at the principal executive offices of the
Corporation not later than the close of business on the ninetieth (90th) day nor
earlier than the close of business on the one hundred twentieth (120th) day
prior to the first anniversary of the preceding year's annual meeting (provided,
however, that in the event that the date of the annual meeting is more than

date, notice by the stockholder must be so delivered not earlier than the close
of business on the one hundred twentieth (120th) day prior to such annual
meeting and not later than the close of business on the later of the ninetieth
(90th) day prior to such annual meeting or the tenth (10th) day following the
day on which public announcement of the date of such meeting is first made by
the Corporation). In no event shall the public announcement of an adjournment or
postponement of an annual meeting commence a new time period (or extend any time
period) for the giving of a stockholder's notice as described above. Such
stockholder's notice shall set forth: (i) as to each person whom the stockholder
proposes to nominate for election or reelection as a director, all information
relating to such person that is required to be disclosed in solicitations of
proxies for election of directors in an election contest or is otherwise
required, in each case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and Rule 14a-11 thereunder (and
such person's written consent to being named in the proxy statement as a nominee
and to serving as a director if elected); (ii) as to any other business that the
stockholder proposes to bring before the meeting, a brief description of the
business desired to be brought before the meeting, the text of the proposal or

language of the proposed amendment), the reasons for conducting such business at
the meeting and any material interest in such business of such stockholder and
the beneficial owner, if any, on whose behalf the proposal is made; and (iii) as
to the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (a) the 

                                      -4-

name and address of such stockholder, as they appear on the Corporation's books,
and of such beneficial owner, (b) the class and number of shares of capital
stock of the Corporation which are owned beneficially and of record by such
stockholder and such beneficial owner, (c) a representation that the stockholder
is a holder of record of stock of the Corporation entitled to vote at such
meeting and intends to appear, in person or by proxy, at the meeting to propose
such business or nomination and (d) a representation whether the stockholder or
the beneficial owner, if any, intends or is part of a group which intends to (A)
deliver a proxy statement and/or form of proxy to holders of at least the
percentage of the Corporation's outstanding capital stock required to approve or
adopt the proposal or elect the nominee and/or (B) otherwise solicit proxies
from stockholders in support of such proposal or nomination. The Corporation may
require any proposed nominee to furnish such other information as it may
reasonably require to determine the eligibility of such proposed nominee to
serve as a director of the Corporation.

     (c) Notwithstanding anything in the second sentence of paragraph (a) of
this Section 10 to the contrary, in the event that the number of directors to be
elected to the Board of Directors at an annual meeting is increased and there is
no public announcement by the Corporation naming all of the nominees for
director or specifying the size of the increased Board of Directors at least one
hundred (100) days prior to the first anniversary of the preceding year's annual
meeting, a stockholder's notice required by this Section 10 shall also be
considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary of the
Corporation at the principal executive offices of the Corporation no later than
the close of business on the tenth (10th) day following the day on which such
public announcement is first made by the Corporation.

     (d) Only such business shall be conducted at a special meeting of
stockholders as shall have been brought before the meeting pursuant to the
Corporation's notice of meeting. Nominations of persons for election to the
Board of Directors may be made at a special meeting of stockholders at which
directors are to be elected pursuant to the Corporation's notice of meeting (i)
by or at the direction of the Board of Directors or (ii) provided that the Board
of Directors has determined that directors shall be elected at such meeting, by
any stockholder of the Corporation who is a stockholder of record at the time
the notice provided for in this Section 10 is delivered to the Secretary of the
Corporation, who shall be entitled to vote at the meeting and upon such
election, and who complies with the notice procedures set forth in this Section
10. In the event the Corporation calls a special meeting of stockholders for the
purpose of electing one or more directors to the Board of Directors, any such
stockholder entitled to vote in such election of directors may nominate a person
or persons (as the case may be) for election to such position or positions as
specified in the Corporation's notice of meeting, if the stockholder's notice
required by paragraph (b) of this Section 10 shall be delivered to the Secretary
at the principal executive offices of the Corporation not earlier than the 

                                      -5-

close of business on the one hundred twentieth (120th) day prior to such special
meeting and not later than the close of business on the later of the ninetieth
(90th) day prior to such special meeting, or the tenth (10th) day following the
day on which public announcement is first made of the date of the special
meeting and of the nominees proposed by the Board of Directors to be elected at
such meeting. In no event shall the public announcement of an adjournment or
postponement of a special meeting commence a new time period (or extend any time
period) for the giving of a stockholder's notice as described above.

     (e) Only such persons who are nominated in accordance with the procedures
set forth in this Section 10 shall be eligible to be elected at an annual or
special meeting of stockholders of the Corporation to serve as directors and
only such business shall be conducted at a meeting of stockholders as shall have
been brought before the meeting in accordance with the procedures set forth in
this Section 10. Except as otherwise provided by law or the Restated Certificate
of Incorporation, the chairman of the meeting shall have the power and duty to
(i) determine whether a nomination or any business proposed to be brought before
the meeting was made or proposed, as the case may be, in accordance with the
procedures set forth in this Section 10 and (ii) if any proposed nomination or
business is not in compliance with this Section 10 (including whether the
stockholder or beneficial owner, if any, on whose behalf the nomination or
proposal is made solicits (or is part of a group which solicits), or fails to so
solicit (as the case may be), proxies in support of such stockholder's proposal
in compliance with such stockholder's representation as required by clause
(iii)(d) of paragraph (a) of this Section 10, to declare that such defective
nomination shall be disregarded or that such proposed business shall not be
transacted.

     (f) For purposes of this Section 10, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service or in a document publicly filed by the
Corporation with the Securities and Exchange Commission pursuant to Section 13,
14 or 15(d) of the Exchange Act.

     (g) Notwithstanding the foregoing provisions of this Section 10, a
stockholder shall also comply with all applicable requirements of the Exchange
Act and the rule and regulations thereunder with respect to the matters set
forth in this Section 10. Nothing in this Section 10 shall be deemed to affect
any rights (i) of stockholders to request inclusion of proposals in the
Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act or
(ii) of the holders of any series of Preferred Stock to elect directors under
specified circumstances.

office at the pleasure of the Board except as may otherwise be approved by the
Board, or until such officer's earlier resignation, removal under these By-Laws
or other termination of employment. Any person may hold more than one office if
the duties can be consistently performed by the same person, to the extent
permitted by the laws of the State of Delaware.

     The Board of Directors, in its discretion, may also at any time elect or
appoint a Chairman of the Board of Directors, who shall be a director, and one
or more vice presidents, assistant secretaries and assistant treasurers and such
other officers as it may deem advisable, each of whom shall hold office at the
pleasure of the Board, except as may otherwise be approved by the Board, or
until such officer's earlier resignation, removal or other termination of
employment, and shall have such authority and shall perform such duties as shall
be prescribed or determined from time to time by the Board or, if not so
prescribed or determined by the Board, as the chief executive officer or the
then senior executive officer may prescribe or determine. The Board of Directors
may require any officer or other employee or agent to give bond for the faithful
performance of duties in such form and with such sureties as the Board may
require.

     Section 2. Duties. Subject to such extension, limitations, and other
                ------
provisions as the Board of Directors or these By-Laws may from time to time

stockholders and of the Board of Directors, if he is a director.

     (b) Vice President. The vice president or vice presidents shall perform
         --------------
such duties as may be assigned to them from time to time by the Board of
Directors or by the president if the Board does not do so. In the absence or
disability of the president, the vice presidents in order of seniority may,
unless otherwise determined by the Board, exercise the powers and perform the
duties pertaining to the office of president, except that if one or more
executive vice presidents has been elected or appointed, the person holding such
office in order of seniority shall exercise the powers and perform the duties of
the office of president.

     (c) Secretary. The secretary, or in the secretary's absence, an assistant
         ---------
secretary shall keep the minutes of all meetings of stockholders and of the

or determined from time to time by the Board of Directors or by the president if
the Board does not do so.

     (d) Treasurer. The treasurer, subject to the order of the Board of
         ---------
Directors, shall have the care and custody of the moneys, funds, valuable papers
and documents of the Corporation (other than such officer's own bond, if any,
which shall be in the custody of the president), and shall have, under the
supervision of the Board of Directors, all the powers and duties commonly
incident to such office. The treasurer shall deposit all funds of the
Corporation in such bank or banks, trust company or trust companies, or with
such firm or firms doing a banking business as may be designated by the Board of
Directors or by the president if the Board does not do so. The treasurer may
endorse for deposit or collection all checks, notes and similar instruments
payable to the Corporation or to its order. The treasurer shall keep accurate
books of account of the Corporation's transactions, which shall be the property
of the Corporation and, together with all of the property of the Corporation 

                                      -11-
<PAGE>
 
in such officer's possession, shall be subject at all times to the inspection
and control of the Board of Directors. The treasurer shall be subject in every
way to the order of the Board of Directors, and shall render to the Board of
Directors and/or the president of the Corporation, whenever they may require it,
an account of all transactions and of the financial condition of the
Corporation. In addition to the foregoing, the treasurer shall have such duties
as may be prescribed or determined from time to time by the Board of Directors
or by the president if the Board does not do so.

officer, director or employee.

                           RESIGNATIONS AND VACANCIES

     Section 1. Resignations. Any director or officer may resign at any time by
                ------------
giving written notice thereof to the Board of Directors, the president or the
secretary. Any such resignation shall take effect at the time specified therein
or, if the time be not specified, upon receipt thereof; and unless otherwise
specified therein, the acceptance of any resignation shall not be necessary to
make it effective.

     Section 2. Vacancies.
                ---------

     (a) Directors. Except for the rights of the holders of any series of
         ---------
preferred stock to elect additional directors, newly created directorships
resulting from any increase in the authorized number of directors and any
vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal, or other cause shall be filled only by the
affirmative vote of a majority of the remaining directors then in office, even
though less than a quorum of the Board of Directors. Any director elected in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the class of directors in which the new directorship was
created or in which the vacancy occurred and until such director's successor is
duly elected and has been qualified. The directors also may reduce the
authorized number of directors by the number of vacancies on the Board. No
decrease in the number of directors constituting the Board of Directors shall
shorten the term of any incumbent director.

     (b) Officers. The Board of Directors may at any time or from time to time
         --------
fill any vacancy among the officers of the Corporation.

                                  CAPITAL STOCK

     Section 1. Certificate of Stock. Every stockholder shall be entitled to a

numbered and setting forth the number and kind of shares represented thereby.
Such certificates shall be signed by the Chairman of the Board, the president or
a vice president and by the treasurer or an assistant treasurer or by the
secretary or an assistant secretary. Any or all of such signatures may be in
facsimile if and to the extent authorized under the laws of the State of
Delaware.

     In case any officer, transfer agent or registrar who has signed or whose
facsimile signature has been placed on a certificate has ceased to be such
officer, transfer agent or registrar before the certificate has been issued,
such certificate may nevertheless be issued and delivered by the Corporation
with the same effect as if such person were such officer, transfer agent or
registrar at the date of issue.

     Section 2. Transfer of Stock. Shares of the capital stock of the
                -----------------
Corporation shall be transferable only upon the books of the Corporation upon
the surrender of the certificate or certificates properly assigned and endorsed
for transfer. If the Corporation has a transfer agent or agents or transfer
clerk and registrar of transfers acting on its behalf, the signature of any
officer or representative thereof may be in facsimile.

     The Board of Directors may appoint a transfer agent and one or more
co-transfer agents and a registrar and one or more co-registrars of transfer and
may make or authorize the transfer agents to make all such rules and regulations
deemed expedient concerning the issue, transfer and registration of shares of
stock.

     Section 3. Record Dates.
                ------------

     (a) In order that the Corporation may determine the stockholders entitled
to notice of or to vote at any meeting of stockholders or any adjournment
thereof or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board of Directors may fix in advance a record date which, in the
case of a meeting, shall not be less than ten (10) nor more than sixty (60) days
prior to the scheduled date of such meeting and which, in the case of any other
action, shall be not more than the maximum or less than the minimum number of
days prior to any such action permitted by the laws of the State of Delaware.

     (b) If no such record date is fixed by the Board, the record date shall be
that prescribed by the laws of the State of Delaware.

                                      -13-
<PAGE>
 
     (c) A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

     Section 4. Lost Certificates. In case of loss or mutilation or destruction
                -----------------
of a stock certificate, a duplicate certificate may be issued upon such terms as
may be determined or authorized by the Board of Directors or by the president if
the Board does not do so.

                                   ARTICLE VII
                     FISCAL YEAR, BANK DEPOSITS, CHECK, ETC.

or end at such time as the Board of Directors may designate.

     Section 2. Bank Deposits, Checks, etc. The funds of the Corporation shall
                ---------------------------
be deposited in the name of the Corporation or of any division thereof in such
banks or trust companies in the United States or elsewhere as may be designated
from time to time by the Board of Directors, or by such officer or officers as
the Board may authorize to make such designations.

     All checks, drafts or other orders for the withdrawal of funds from any
bank account shall be signed by such person or persons as may be designated from
time to time by the Board of Directors. The signatures on checks, drafts or
other orders for the withdrawal of funds may be in facsimile if authorized in
the designation.

                                  ARTICLE VIII
                                BOOKS AND RECORDS

     Section 1. Place of Keeping Books. Unless otherwise expressly required by
                ----------------------
the laws of the State of Delaware, the books and records of the Corporation may
be kept outside of the State of Delaware.

     Section 2. Examination of Books. Except as may otherwise be provided by the
                --------------------
laws of the State of Delaware, the Restated Certificate of Incorporation or
these By-Laws, the Board of Directors shall have power to determine from time to
time whether and to what extent and at what times and places and under what
conditions any of the accounts, records and books of the Corporation are to be
open to the inspection of any stockholder. No stockholder shall have any right
to inspect any account or book or document of the Corporation except as
prescribed by the laws of the State of Delaware or authorized by express
resolution of the Board of Directors.

                                     NOTICES

     Section 1. Requirements of Notice. Whenever notice is required to be given
                ----------------------
by the laws of the State of Delaware, the Restated Certificate of Incorporation
or these By-Laws, it shall not mean personal notice unless so specified, but
such notice may be given in writing by depositing the same in a post office,
letter box, or mail chute postpaid and addressed to the person to whom such
notice is directed at the address of such person on the records of the
Corporation, and such notice shall be deemed given at the time when the same
shall be thus mailed.

     Section 2. Waivers. Any stockholder, director or officer may, in writing or
                -------
by telegram or cable, at any time waive any notice or other formality required
by statute, the Restated Certificate of Incorporation or these By-Laws. Such
waiver of notice, whether given before or after any meeting or action, shall be
deemed equivalent to notice. Presence of a stockholder either in person or by
proxy at any stockholders meeting and presence of any director at any meeting of
the Board of Directors shall constitute a waiver of such notice as may be
required by any statute, the Restated Certificate of Incorporation or these
By-Laws.

                                    ARTICLE X

                               POWERS OF ATTORNEY

     The Board of Directors may authorize one or more of the officers of the
Corporation to execute powers of attorney delegating to named representatives or
agents power to represent or act on behalf of the Corporation, with or without
power of substitution.

     In the absence of any action by the Board, the president, any vice
president, the secretary or the treasurer of the Corporation may execute for and
on behalf of the Corporation waivers of notice of stockholders meetings and
proxies for such meetings in any company in which the Corporation may hold
voting securities.

                                   ARTICLE XII
                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 1. Definitions. As used in this article, the term "person" means
                -----------
any past, present or future director or officer of the Corporation or any
subsidiary or operating division thereof.

     Section 2. Indemnification Granted. The Corporation shall indemnify, to the
                -----------------------
full extent and under the circumstances permitted by the General Corporation Law
of the State of Delaware in effect from time to time, any person as defined
above, made or threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person is or was a director or
officer of the Corporation or a subsidiary or operating division thereof, or is
or was serving at the specific request of the Corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, or by reason of any action alleged to have been taken
or omitted in such capacity, against costs, charges, expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person or on such person's behalf in connection with
such action, suit or proceeding and any appeal therefrom, if such person acted
in good faith and in a manner he or she reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe that his or
her conduct was unlawful. The termination of any action, suit, or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he or she reasonably believed to be
in or not opposed to the best interests of the Corporation, and, with respect to
any criminal action or proceeding, had reasonable cause to believe that such
conduct was unlawful.

     Section 3. Requirements for Indemnification Relating to an Action or Suit
                --------------------------------------------------------------
by or in the Right of the Corporation. The Corporation shall indemnify any
- -------------------------------------
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that such
person is or was a director or officer of the Corporation, or a subsidiary
thereof or a designated officer of an operating division of the Corporation, or
is or was serving at the specific request of the Corporation as a director or
officer of another corporation, partnership, joint venture, trust or other
enterprise, or by reason of any action alleged to have been taken or omitted in
such capacity, against costs, charges and expenses (including attorneys' fees)
actually and reasonably incurred by such person or on such person's behalf in
connection with the defense or settlement of such action or suit and any appeal
therefrom, if such person acted in good faith and in a manner that such person
reasonably believed to be in or not opposed to the best interest of the

                                      -16-
<PAGE>
 
Corporation except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the Court of
Chancery of Delaware or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of such liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such costs, charges and expenses which the
Court of Chancery or such other court shall deem proper.

     Section 4. Success on Merits of Any Action. Notwithstanding any other
                -------------------------------
provision of this Article, to the extent that a director or officer of the
Corporation or any subsidiary or operating division thereof has been successful
on the merits or otherwise, including, without limitation, the dismissal of an
action without prejudice, in defense of any action, suit or proceeding referred
to in this Article, or in defense of any claim, issue or matter therein, such
person shall be indemnified against all costs, charges and expenses (including
attorneys' fees) actually and reasonably incurred by such person or on such
person's behalf in connection therewith.

     Section 5. Determination of Standard of Conduct. Any indemnification under
                ------------------------------------
Sections 2 and 3 of this Article (unless ordered by a court) shall be paid by
the Corporation only after a determination has been made (1) by the directors
who were not parties to such action, suit or proceeding, or (2) if such quorum
is not obtainable, or even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders, that indemnification of the director or officer is proper in the
circumstances of the specific case because such person has met the applicable
standard of conduct set forth in Sections 2 and 3 of this Article.

     Section 6. Advance Payment; Representation by Corporation. Costs, charges
                ----------------------------------------------
and expenses (including attorneys' fees) incurred by a person referred to in
Sections 2 and 3 of this Article in defending a civil or criminal action, suit
or proceeding shall be paid by the Corporation in advance of the final
disposition of such action, suit or proceeding; provided, however, that the
payment of such costs, charges and expenses incurred by a director or officer in
such capacity as officer or director (and not in any other capacity and which
service was or is rendered by such person while a director or officer) in
advance of the final disposition of such action, suit or proceeding shall be
made only upon receipt of an undertaking by or on behalf of the director or
officer to repay all amounts so advanced in the event that it shall ultimately
be determined that such director or officer is not entitled to be indemnified by
the Corporation as authorized in this Article. Such costs, charges and expenses
incurred by other employees and agents may be so paid upon such terms and
conditions, if any, as the Board of Directors deems appropriate. The Corporation
may, in the manner set forth above, and upon approval of such director or
officer, authorize the Corporation's counsel to represent such person, in any

                                      -17-
<PAGE>
 
action, suit or proceeding, whether or not the Corporation is a party to such
action, suit or proceeding.

     Section 7. Procedure for Obtaining Indemnity. Any indemnification under
                ---------------------------------
Sections 2, 3 and 4, or advance of costs, charges and expenses under Section 6,
of this Article shall be made promptly, and in any event within sixty (60) days,
of the written notice of the director or officer. The right to indemnification
or advances as granted by this Article shall be enforceable by the director or
officer in any court of competent jurisdiction if the Corporation denies such
request, in whole or in part, or if no disposition thereof is made within sixty
(60) days. Such person's costs and expenses incurred in connection with
successfully establishing a right to indemnification or advancement of expenses,
in whole or in part, in any action shall also be indemnified by the Corporation.
It shall be a defense to any such action (other than an action brought to
enforce a claim for the advance of costs, charges and expenses under Section 6
of this Article where the required undertaking, if any, has been received by the
Corporation) that the claimant has not met the standard of conduct set forth in
Section 2 or 3 of this Article, but the burden of proving such defense shall be
on the Corporation. Neither failure of the Corporation (including its Board of
Directors, its independent legal counsel, and its stockholders) to have made a
determination that indemnification of the claimant is proper in the
circumstances because such person has met the applicable standard of conduct set
forth in Section 2 or 3 of this Article, nor the fact that there has been an
actual determination by the Corporation (including its directors, its
independent legal counsel and its stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that the claimant has not met the applicable standard of conduct.

     Section 8. Indemnification Not Exclusive. This right of indemnification
                -----------------------------
shall not be deemed exclusive of any other rights to which a person indemnified
herein may be entitled by law, agreement, vote of stockholders or disinterested
directors or otherwise, and shall continue as to a person who has ceased to be a
director, officer, designated officer, employee or agent and shall inure to the
benefit of the heirs, executors, administrators and other legal representatives
of such person. It is not intended that the provisions of this Article be
applicable to, and they are not to be construed as granting indemnity with
respect to, matters as to which indemnification would be in contravention of the
laws of Delaware or of the United States of America, whether as a matter of
public policy or pursuant to statutory provision.

     Section 9. Invalidity of Certain Provisions. If this Article or any portion
                --------------------------------
hereof shall be invalidated on any ground by any court of competent
jurisdiction, then the Corporation shall nevertheless indemnify each director,
officer, employee and agent of the Corporation or any subsidiary or operating
division thereof as to costs, charges and expenses (including attorneys' fees),

                                      -18-
<PAGE>
 
judgments, fines and amounts paid in settlement with respect to any action, suit
or proceeding, whether civil, criminal, administrative or investigative,
including any action by or in the right of the Corporation, to the full extent
permitted by any applicable portion of this Article that shall not have been
invalidated and to the full extent permitted by applicable law.

     Section 10. Miscellaneous. The Board of Directors may also on behalf of the
                 -------------
Corporation grant indemnification to any individual other than a person defined
herein to such extent and in such manner as the Board in its sole discretion may
from time to time and at any time determine.

                                  ARTICLE XIII
                                   AMENDMENTS

     These By-Laws may be altered, amended or repealed, and new By-Laws may be
made, by the affirmative vote of a majority of the directors then in office.

            The parties hereto agree as follows:


                                   ARTICLE I
                                  DEFINITIONS

            Section 1.01 Definitions. All capitalized terms used in this

Agreement or in any Appendix, Schedule or Exhibit hereto which are not otherwise
defined herein or therein shall have the respective meanings set forth in the
Appendix attached hereto identified as the Definitions Appendix. The Definitions
Appendix is incorporated herein by reference in its entirety and is a part of
this Agreement to the same extent as if it had been set forth in this Section
1.01 in full.

            Section 1.02 Accounting Terms and Determinations. Unless otherwise
                         -----------------------------------
specified herein, all accounting terms used herein shall be interpreted, all
accounting determinations hereunder shall be made, and all financial statements
required to be delivered hereunder shall be prepared, in accordance with
generally accepted accounting principles in the United States of America as in
effect from time to time, applied on a basis consistent (except for changes
concurred in by the Borrower's independent public accountants) with the most
recent audited consolidated financial statements of the Borrower and its
Consolidated Subsidiaries delivered to the Bank.


                                  ARTICLE II
                                  THE CREDIT

conditions set forth in this Agreement, to make Loans to the Borrower from time

principal amount of Loans at any one time outstanding will not exceed the lesser
of (i) the Commitment and (ii) the Borrowing Base. Within the foregoing limit,
the Borrower may borrow, prepay and reborrow Loans at any time during the
Revolving Credit Period.

            Section 2.02 Methods of Borrowing.
                         --------------------

later than 12:00 P.M. (local time in Jacksonville, Florida) on the date of each
requested Loan, specifying the date of such Loan and the amount of such Loan.
<PAGE>
 
   (b) Operating Account Overdrafts. If on any day Items are presented to the
       ----------------------------
Bank for payment against the Operating Account which Items, in the aggregate,
would, if paid in full, cause the Available Balance in the Operating Account on
such day to be less than $0, such presentation shall be deemed to be a request
by the Borrower for a Loan on the date of such presentation in an amount equal
to the amount (rounded upward to the nearest $1,000) required to cause such
Available Balance to equal $0.

   (c) Overdrafts in Other Accounts. The Bank may, at its option, pay any Item
       ----------------------------
which will cause any deposit account maintained by the Borrower with the Bank to
become overdrawn, and such payment shall be deemed a Loan hereunder.

   Section 2.03 Funding of Loans. The Bank shall disburse the proceeds of each
                ----------------
Loan requested, or deemed to be requested, pursuant to Section 2.02 as follows:

the Bank's address referred to in Section 8.01.

   (b) The proceeds of each Loan under Section 2.02(b) or (c) shall be
disbursed by the Bank by way of direct payment of the relevant Item or by way of
deposit to the Operating Account of the amount set forth in Section 2.02(b), as
the case may be.

   Section 2.04 Note.
                ----
   (a) Evidence of Loans. The Loans shall be evidenced by a single Note
       -----------------
payable to the order of the Bank in an amount equal to the aggregate unpaid
principal amount of the Loans.

   (b) Records of Amounts Due. The Bank shall record the date and amount of
       ----------------------
each Loan made by it and the date and amount of each payment of principal made
by the Borrower with respect thereto, and may, if the Bank so elects in
connection with any transfer or enforcement of the Note, endorse on the schedule
forming a part thereof appropriate notations to evidence the foregoing
information with respect to each such Loan then outstanding; provided that the
                                                             --------
failure of the Bank to make any such recordation or endorsement shall not affect
the obligations of the Borrower hereunder or under the Note. The Bank is hereby
irrevocably authorized by the Borrower so to endorse the Note and to attach to
and make a part of the Note a continuation of any such schedule as and when
required. The Bank shall send the Borrower a copy of any endorsements and
continuations so made.

   Section 2.05 Interest Rate.
                -------------

becomes due, 


                                      -2-
<PAGE>
 
at a rate per annum equal to the applicable LIBOR-based Rate for such day. Such
interest shall be payable for each month in arrears on the first day of the
immediately succeeding calendar month.

   The "Adjusted London Interbank Offered Rate" means on any day a rate per
annum equal to the quotient obtained (rounded upward, if necessary, to the next
higher 1/100 of 1 %) by dividing (i) the London Interbank Offered Rate for such
day by (ii) 1.00 minus the Euro-Dollar Reserve Percentage.

   "LIBOR-based Rate" means for any day, the sum of (i) the Adjusted London
Interbank Offered Rate for such day plus (ii) 200 basis points.

   The "London Interbank Offered Rate" means the rate per annum designated as
the British Bankers' Association settlement rate as of 11:00 A.M. (London time)
for one month deposits in Dollars in the London interbank market that appears on
the display on page 3750 (under the caption "USD" of the Telerate Services,
Incorporated screen (the "Telerate Screen") (or on such other display as may
replace such page on the Telerate Screen) at such time) each Euro-Dollar
Business Day; provided that if no offered quotations appear on the Telerate
              --------
Screen or if quotations are not given on the Telerate Screen for such one month
period, then the London Interbank Offered Rate shall mean the rate per annum
determined by the Bank at which United States Dollars in the amount of
$5,000,000 are being offered to leading banks in the London interbank market for
Dollar deposits at approximately 11:00 A.M. London time two Euro-Dollar Business
Days prior to such day for settlement in immediately available funds by leading
banks in the London interbank market for a one month period.

   "Euro-Dollar Reserve Percentage" means for any day that percentage (expressed
as a decimal) which is in effect on such day, as prescribed by the Board of
Governors of the Federal Reserve System (or any successor) for determining the
maximum reserve requirement for a member bank of the Federal Reserve System in
New York City with deposits exceeding five billion dollars in respect of
"Euro-currency liabilities" (or in respect of any other category of liabilities
which includes deposits by reference to which the interest rate on Loans is
determined or any category of extensions of credit or other assets which
includes loans by a non-United States office of the Bank to United States
residents). The Adjusted London Interbank Offered Rate shall be adjusted
automatically on and as of the effective date of any change in the Euro-Dollar
Reserve Percentage.

   The LIBOR-based Rate shall change from time to time with changes to occur on
the date the London Interbank Offered Rate changes on the Telerate Screen page
3750, or if such rate is not available, by reference to the rate being offered
to leading banks.

   (b) Overdue Amounts. Any overdue principal of or interest on any Loan shall
       ---------------
bear interest, payable on demand, for each day from and including the date
payment thereof was 



                                      -3-
<PAGE>
 
due to but excluding the date of actual payment, at a rate per annum equal to
the sum of 2% plus the LIBOR-based Rate applicable to such Loan on such day.


   Section 2.06 Fees.
                ----

   (a) Unused Commitment Fee. The Borrower shall pay to the Bank an unused
       ---------------------
commitment fee (the "Commitment Fee") for each day at a rate per annum equal to
the product of (i) 12.5 basis points multiplied by (ii) the excess of the
Commitment over the aggregate amount of the Loans on such day. Such unused
commitment fee shall accrue from and including the Effective Date to but
excluding the Termination Date (or earlier date of termination of the Commitment
in its entirety) and shall be payable quarterly in arrears on each Quarterly
Date and on the Termination Date.

   (b) Audit Fee. The Borrower shall pay an audit fee, not to exceed $2,500.00,
       ---------

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

   (a) Optional Termination or Reductions of Commitment. The Borrower may,
       ------------------------------------------------
upon at least three Business Days' notice to the Bank, (i) terminate the
Commitment at any time, if no Loans are outstanding at such time or (ii) reduce
from time to time the amount of the Commitment in excess of the aggregate
outstanding principal amount of the Loans. If the Commitment is terminated in
its entirety, all accrued fees shall be payable on the effective date of such
termination.

   (b) Optional Extension of Commitment.
       --------------------------------

       (i) The Revolving Credit Period shall be for an initial term of two
years. The Bank may elect, by notice to the Borrower not less than 15 days and
not more than 45 days prior to the first anniversary of the Effective Date or
the first anniversary of an Extension Date (as applicable, an "Anniversary
Date"), to extend the Revolving Credit Period until the second anniversary of
such Anniversary Date (each of the first and subsequent Anniversary Dates on
which the Revolving Credit Period is extended hereunder being referred to herein
as an "Extension Date"). Failure by the Bank to notify the Borrower of such
election within the above time period shall be deemed to constitute an election
by the Bank not to extend the Revolving Credit Period.

       (ii) If the Bank shall have elected to extend the Revolving Credit Period
as provided in this Section 2.07(b), the Borrower shall deliver to the Bank, on
the applicable Extension Date (and in exchange for the Note of the Borrower then
held by the Bank), a Note maturing on the second anniversary of such Extension
Date in the principal amount of the Commitment.

       (iii) If the Bank shall have elected to extend the Revolving Credit
Period as provided in this Section 2.07(b), then the Revolving Credit Period
shall continue until the second anniversary of the Extension Date in effect, and
the term "Termination Date", as used herein, shall mean such second anniversary.

   Section 2.08 Maturity and Repayment of Loans.
                -------------------------------   

   (a) Maturity of Termination Date. Each Loan shall mature, and the principal
       ----------------------------
amount thereof shall be due and payable, on the Termination Date.

   (b) Mandatory Prepayments of Loans Exceeding Borrowing Base. If on any day
       -------------------------------------------------------
the aggregate outstanding principal amount of all Loans exceeds the Borrowing
Base, the Borrower shall prepay, and there shall become due and payable, on such
date the principal amount of the Loans equal to such excess, together with
interest thereon to the date of repayment.

   (c) Mandatory Repayments from Operating Account.
       -------------------------------------------

       (i) Deposits of Proceeds to Operating Account. The Borrower shall
           -----------------------------------------
     instruct all Account Debtors and other Persons obligated in respect of
     Accounts and other Collateral to make all payments in respect of the
     Accounts or other Collateral directly to the Bank (by instructing that such
     payments be remitted to a post office box which shall be in the name of the
     Borrower but under the control of the Bank). Except as provided in Section
     3.04 of the Security Agreement, all such payments made to the Bank shall be
     deposited in the Operating Account. In addition to the foregoing, the
     Borrower agrees that if the proceeds of any Collateral (including the
     payments made in respect of Accounts) shall be received by it, the Borrower
     shall, unless Section 3.04 of the Security Agreement shall require
     otherwise, as promptly as possible deposit such proceeds to the Operating
     Account. Until so deposited, all such proceeds shall be held in trust by
     the Borrower for and as the property of the Bank and shall not be
     commingled with any other funds or property of the Borrower. The Borrower
     hereby irrevocably authorizes and empowers the Bank, its officers,
     employees and authorized agents to endorse and sign its name on all checks,
     drafts, money orders or other media of payment so delivered, and such
     endorsements or assignments shall, for all purposes, be deemed to have been
     made by the Borrower prior to any endorsement or assignment thereof by the
     Bank. The Bank may use any convenient or customary means for the purpose of
     collecting such checks, drafts, money orders or other media of payment.

       (ii)Loans Due to Extent of Available Balance. Each Business Day, that
           ----------------------------------------
     principal amount of the Loans equal to the then Available Balance shall

be withdrawn by the Bank each Business Day and applied to repay the Obligations
which are then due and payable (including those which become due and payable on
such date pursuant to subsection (ii) above).

   (d)   Optional Prepayments of Loans. The Borrower may upon at least one
         -----------------------------
Business Day's notice to the Bank, prepay any Loan, in whole at any time, or
from time to time in part, without penalty, by paying the principal amount to be
prepaid together with accrued interest thereon to the date of prepayment. The
notice of prepayment delivered by the Borrower to the Bank shall not be
revocable by the Borrower following its receipt by the Bank.

   Section 2.09 General Provisions as to Payments. The Borrower shall make each
                ---------------------------------
payment of principal of and interest on the Loans and fees hereunder not later

without set-off, counterclaim or other deduction, in Federal or other funds
immediately available in Jacksonville, Florida, to the Bank at its address
referred to in Section 8.01. The Borrower hereby irrevocably authorizes the Bank
to deduct from the Operating Account at any time such amount as may then be
necessary to pay Obligations referred to in clause (ii)(A) of the definition of
Available Balance. Whenever any payment of principal of, or interest on, the
Loans or of fees shall be due on a day which is not a Business Day, the date for
payment thereof shall be extended to the next succeeding Business Day. If the
date for any payment of principal is extended by operation of law or otherwise,
interest thereon shall be payable for such extended time.

   Section 2.10 Computation of Interest and Fees. Interest on Loans hereunder
                --------------------------------

Subsidiaries conduct their business without infringement or claim of
infringement of any material license, patent, trademark, trade name, service
mark, copyright, trade secret or any other intellectual property right of others
and there is no infringement or, except as set forth on Schedule 4.12, claim of
infringement by others of any material license, patent, trademark, trade name,
service mark, copyright, trade secret or other intellectual property right of

         Section 4.13 No Burdensome Restrictions. No contract, lease, agreement 
                      --------------------------

or by which any of its property is bound or affected, no charge, corporate
restriction, judgment, decree or order and no provision of applicable law or
governmental regulation has had or is reasonably expected to have a Material
Adverse Effect.

         Section 4.14 Environmental Matters. In the ordinary course of its 
                      ---------------------
business, the Borrower conducts an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Borrower and its
Subsidiaries, in the course of which it identifies and evaluates associated
liabilities and costs (including, without limitation, any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned, any capital or operating expenditures required to achieve or
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted at any such facility, any costs or liabilities in connection with off-
site disposal of wastes or Hazardous Substances, and any actual or potential
liabilities to third parties, including employees, and any related costs and
expenses). On the basis of this review, the Borrower has reasonably concluded
that such associated liabilities and costs, including the costs of compliance
with Environmental Laws, are unlikely to have a material adverse effect on the
business, financial condition, results of operations or prospects of the
Borrower and its Consolidated Subsidiaries, considered as a whole.

         Section 4.15 Accounts. With respect to each Account, all records,

effect thereto, no Default shall have occurred; or (ii) the change in the
Borrower's form of business entity to a corporation taxed in accordance with
Subchapter C of the Internal Revenue Code, provided that (A) such successor
corporation shall expressly assume in a manner satisfactory to the Bank the due
and punctual performance and observance of each covenant and obligation of the
Borrower under this Agreement, the Note, and the other Loan Documents to which
it is a party; and (B) the Loan Documents are modified accordingly to the
satisfaction of the Bank.

         Section 5.05 Compliance with Laws. The Borrower will comply, and will
                      --------------------
cause each of its Subsidiaries to comply, with all applicable laws, ordinances,
rules, regulations, and requirements of governmental authorities (including,
without limitation, Environmental Laws, ERISA and the rules and regulations
thereunder) except (i) where the necessity of compliance therewith is contested
in good faith by appropriate proceedings or (ii) where noncompliance could not
reasonably be expected to have a Material Adverse Effect.

         Section 5.06 Accounting: Inspection of Property, Books and Records.
                      -----------------------------------------------------
The Borrower will keep, and will cause each of its Subsidiaries to
keep, proper books of record and account in which full, true and correct entries
in conformity with generally accepted accounting principles shall be made of all
dealings and transactions in relation to their respective businesses and
activities, will maintain, and will cause each of its Subsidiaries to maintain,
their respective fiscal reporting periods on the present basis and will permit,
and will cause each of its Subsidiaries to permit, representatives of the Bank
to visit and inspect any of their respective properties, to examine and make
copies from any of their respective books and records and to discuss their
respective affairs, finances and accounts with their officers, employees and
independent public accountants, all at such reasonable times and as often as may
reasonably be desired, but not more frequently than annually unless a Default
has occurred. Notwithstanding the above, the Borrower shall be permitted to make
adjustments to its books of record and 

                                      -18-
<PAGE>
 
accounts as may be required or as may be requested by an audit or outside
review, so long as the purpose of such adjustment is to bring said books or
accounts into conformity with generally accepted accounting principles.

         Section 5.07 Collection of Accounts. The Borrower shall use its best
                      ----------------------
efforts to cause to be collected from each Account Debtor, as and when due, any
and all amounts owing under or on account of each Account (including, without
limitation, Accounts which are delinquent, such Accounts to be collected in
accordance with lawful collection procedures) and shall apply forthwith upon
receipt thereof all such amounts as are so collected to the outstanding balance
of such Account. The Borrower may rescind or cancel any indebtedness or
obligation evidenced by any Account, modify, make adjustments to, extend, renew,
compromise or settle any material dispute, claim, suit or legal proceeding
relating to or sell or assign any Account, or interest therein, provided that
                                                                --------
the Borrower obtains the written consent of the Bank prior to doing any of the
foregoing (which consent shall not be unreasonably or untimely withheld or
delayed) Notwithstanding the foregoing, subject to the rights of the Bank under
the Loan Documents, unless a Default or an Event of Default shall have occurred
and be continuing, the Borrower may allow in the ordinary course of business as
adjustments to amounts owing under its Accounts (i) an extension or renewal of
the time or times of payment, or settlement for less than the total unpaid
balance, which the Borrower finds appropriate in accordance with sound business
judgment and (ii) a refund or credit due as a result of discounts, over-billings
and miscellaneous credits, all in accordance with the Borrower's ordinary course
of business consistent with its historical collection practices. The reasonable
costs and expenses (including, without limitation, reasonable attorneys' fees)
of collection, whether incurred by the Borrower or the Bank, shall be borne by
the Borrower. Upon the sale or assignment of any Account as allowed by this
Section 5.07, the Bank will (as soon as reasonably practicable after receipt of
notice from the Borrower requesting the same but at the expense of the Borrower)
send the Borrower, for each jurisdiction in which a UCC financing statement is
on file to perfect the security interests granted to the Bank hereunder, a
termination statement to the effect that the Bank no longer claims a security
interest under such financing statement.

         Section 5.08 Notification to Account Debtors. Upon the effectiveness of
                      -------------------------------
this Agreement, the Borrower will promptly notify each Account Debtor in respect
of any Account or Instrument that any payments due or to become due in respect
of such Collateral are to be made in the name of the Borrower to such address
and post office box as shall be specified by the Bank. Except as set forth in
Section 3.04 of the Security Agreement, each such payment shall, upon receipt by
the Bank, be deposited in the Operating Account in accordance with Section
2.08(c). In the event the Borrower, in good faith, fails to notify any Account
Debtor as required hereby, the Borrower shall have 30 days from the earlier of
(i) becoming aware of such failure, or (ii) being made aware of such failure, to
comply with this Section. Upon the occurrence of a Default or an Event of
Default, the Borrower will promptly notify (and the Borrower hereby authorizes
the Bank so to notify) each Account Debtor in respect of any Account or
Instrument that such Collateral has been assigned to the Bank and that any
payments 

                                      -19-
<PAGE>
 
due or to become due in respect of such Collateral are to be made directly to
the Bank in accordance with Section 3.04 of the Security Agreement.

         Section 5.09 Restriction on Liens. The Borrower will not, and will not
                      --------------------
permit any of its Subsidiaries to, create, incur, assume or suffer to exist any
Lien upon or with respect to any Collateral, or sell any Collateral subject to
an understanding or agreement, contingent or otherwise, to repurchase such
Collateral (including sales of accounts receivable or notes with recourse to the
Borrower or any of its Subsidiaries) or assign any right to receive income, or
file or permit the filing of any financing statement under the Uniform
Commercial Code as in effect in any applicable jurisdiction or any other similar
notice of Lien under any similar recording or notice statute; provided that the
                                                              --------

assumption or existence of the following (with such Liens described below being
herein referred to as "Permitted Liens"):

                  (ii)     Liens for taxes not yet due or Liens for taxes being
     contested in good faith and by appropriate proceedings for which adequate
     reserves (in the good faith judgment of the management of the Borrower)
     have been established; and

                  (iii)    Liens imposed by law securing the charges, claims,
     demands or levies of carriers, warehousemen, mechanics and other like
     persons which were incurred in the ordinary course of business which (A) do
     not in the aggregate materially detract from the value of the property or
     assets subject to such Lien or materially impair the use thereof in the
     operation of the business of the Borrower or any Subsidiary or (B) are
     being contested in good faith by appropriate proceedings, which proceedings
     have the effect of preventing the forfeiture or sale of the property or
     assets subject to such lien.

         Section 5.10 Limitation on Guarantees. Neither the Borrower nor any of
                      ------------------------
its Subsidiaries shall Guarantee any Debt of any Person or Persons in excess of
$100,000.00 in the aggregate at any time.

   or compliance by the Bank with any request or directive (whether or not
   having the force of law) of any such authority, central bank or comparable
   agency:

                        (i)    shall subject the Bank to any tax, duty or other
      charge with respect to its Loans, the Note or its obligation to make
      Loans, or shall change the basis of taxation of payments to the Bank of
      the principal of or interest on its Loans or any other amounts due under
      this Agreement in respect of its Loans or its obligation to make Loans
      (except for changes in the rate of tax on the overall net income of the
      Bank imposed by the jurisdiction in which the Bank's principal executive
      office is located); or

                       (ii)   shall impose, modify or deem applicable any
      reserve (including, without limitation, any such requirement imposed by
      the Board of Governors of the

                                      -25-

      Federal Reserve System, but excluding any such requirement included in an
      applicable Euro-Dollar Reserve Percentage, special deposit, insurance
      assessment or similar requirement against assets of, deposits with or for
      the account of, letters of credit issued or participated in by, or other
      credit extended by, the Bank or shall impose on the Bank or on the United
      States market for certificates of deposit or the London interbank market
      any other condition affecting its Loans, the Note or its obligation to
      make Loans;

and the result of any of the foregoing is to increase the cost to the Bank of
making or maintaining any Loan, or to reduce the amount of any sum received or
receivable by the Bank under this Agreement or under the Note with respect
thereto, by an amount deemed by the Bank to be material, then, until the Bank
notifies the Borrower that the circumstances giving rise to such increased costs
no longer exist, each Loan then outstanding which bears interest at the
LIBOR-based Rate shall be converted immediately to a Base Rate Loan and all new
Loans shall be Base Rate Loans.

                  (b)      Capital Adequacy. If the Bank shall have determined
                           ----------------
that, after the date hereof, the adoption of any applicable law, rule or
regulation regarding capital adequacy, or any change in any such 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 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 capital of the Bank (or its Parent) as a consequence of the
Bank's obligations hereunder to a level below that which the Bank could have
achieved but for such adoption, change, request or directive (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by the Bank to be material, then, until the Bank notifies the Borrower that the
circumstances giving rise to such law, rule, regulation no longer exist, each
Loan then outstanding which bears interest at the LIBOR-based Rate shall be
converted immediately to a Base Rate Loan and all new Loans shall be Base Rate
Loans.

                  (c)      Notices. The Bank will promptly notify the Borrower
                           -------
of any event of which it has knowledge, occurring after the date hereof, that
will entitle the Bank to convert the Loans pursuant to this Section. A
certificate of the Bank asserting its right to do so under this Section and
setting forth in reasonable detail the circumstances giving rise to such action
hereunder shall be conclusive in the absence of manifest error.

based Loans. Upon the occurrence of any event or condition set forth in Section
- -----------
7.02 or 7.03, each Loan then outstanding which bears interest at the LIBOR-based
Rate shall be converted immediately to a Base Rate Loan and all new Loans shall
be Base Rate Loans. If the Bank notifies the Borrower that the circumstances
giving rise to such change in interest rate no longer apply, the principal
amount of each such Base Rate Loan shall cease immediately to constitute a Base
Rate Loan and shall thereafter bear interest in accordance with Section 2.05(a).

thereof nor shall any single or partial exercise thereof preclude any other or

The rights and remedies provided herein shall be cumulative and not exclusive of
any rights or remedies provided by law.

                  Section 8.03 Expenses. The Borrower shall pay (i) all
                               --------

                  Section 8.05 Successors and Assigns. The provisions of this 
                               ----------------------

assigns, except that the Borrower may not assign or otherwise transfer any of
its rights under this Agreement without the prior written consent of the Bank.
    
                  Section 8.06 Governing Law. This Agreement and the Note shall
                               -------------
be governed by and construed in accordance with the laws of the Commonwealth of
Virginia.

                  Section 8.07 Arbitration: Submission to Jurisdiction.
                               ------------
                  (a)      Upon demand of any party hereto, whether made before
or after institution of any judicial proceeding, any dispute, claim or
controversy arising out of, connected with or relating to this Agreement, the
Note or any other Loan Document ("Disputes") between parties to this Agreement
shall be resolved by binding arbitration as provided herein. Institution of a
judicial proceeding by a party does not waive the right of that party to demand
arbitration hereunder. Disputes may include, without limitation, tort claims,
counterclaims, disputes as to whether a matter is subject to arbitration, claims
brought as class actions, claims arising from loan documents executed in the
future, or claims arising out of or connected with the transaction reflected by
this Agreement.

                  Arbitration shall be conducted under and governed by the
Commercial Financial Disputes Arbitration Rules (the "Arbitration Rules") of the
American Arbitration Association (the "AAA") and Title 9 of the U.S. Code. All
arbitration hearings shall be conducted in the city in which is located the
office of the Bank identified in Section 8.01 as the place where notices are to
be sent to the Bank. The expedited procedures set forth in Rule 51 et seq. of
the Arbitration Rules shall be applicable to claims of less than $1,000,000. All
applicable statutes of limitation shall apply to any Dispute. A judgment upon
the award may be entered in any court having jurisdiction. The panel from which
all arbitrators are selected shall be comprised of licensed attorneys. The
single arbitrator selected for expedited procedure shall be a retired judge from
the highest court of general jurisdiction, state or federal, of the state where
the hearing will be conducted or if such person is not available to serve, the
single arbitrator may be a licensed attorney. Notwithstanding the foregoing,
this arbitration provision does not apply to disputes under or related to
Derivatives Obligations.

                  (b)      Notwithstanding the preceding binding arbitration
provisions, the Bank and the Borrower agree to preserve, without diminution,
certain remedies that any party hereto may employ or exercise freely,
independently or in connection with an arbitration proceeding or after an
arbitration action is brought. The Bank and the Borrower shall have the right to
proceed in any court of proper jurisdiction or by self-help to exercise or
prosecute the following remedies, as applicable: (i) all rights to foreclose
against any real or personal property or other security by exercising a power of
sale granted under any Loan Document or under applicable law or by judicial
foreclosure and sale, including a proceeding to confirm the sale; (ii) all
rights of self-help including peaceful occupation of real property and
collection of rents, set-off, and peaceful possession of personal property;
(iii) obtaining provisional or ancillary remedies including injunctive relief,
sequestration, garnishment, attachment, appointment of receiver and filing an

                                      -28-
<PAGE>
 
involuntary bankruptcy proceeding; and (iv) when applicable, a judgment by
confession of judgment. Preservation of these remedies does not limit the power
of an arbitrator to grant similar remedies that may be requested by a party in a
Dispute.

                  The Borrowers and the Bank agree that they shall not have a
remedy of punitive or exemplary damages against the other in any Dispute and
hereby waive any right or claim to punitive or exemplary damages they have now
or which may arise in the future in connection with any Dispute whether the
Dispute is resolved by arbitration or judicially.

                  (c)      Any legal action or proceeding with respect to this
Agreement, the Note or any other Loan Document or any document related hereto or
thereto may be brought in the courts of the Commonwealth of Virginia or of the
United States of America for the Western District of Virginia, and by execution
and delivery of this Agreement the Borrower hereby accepts for itself and in
respect of its property, generally and unconditionally, the nonexclusive
jurisdiction of the aforesaid courts. The Borrower hereby irrevocably and
unconditionally waives any objection, including without limitation, any
objection to the laying of venue or based on the grounds of the forum non
                                                                ---------
conveniens which it now or hereafter may have to the bringing of any action or
- ----------
proceeding in such respective jurisdictions. Service of process in any such case
may be had against the Borrower by delivery in accordance with the notice
provisions herein or as otherwise permitted by law, and the Borrower agrees that
such service shall be valid in all respects for establishing personal
jurisdiction over it.

                  Section 8.08 Counterparts; Integration; Effectiveness. This
                               ----------------------------------------
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument. Each of this Agreement, the Note and the other Loan
Documents shall be deemed to incorporate the other of said documents by
reference and all of said documents shall constitute the entire agreement and
understanding among the parties hereto and supersede any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof. This Agreement shall become effective upon receipt by the Bank of
counterparts hereof signed by each of the parties hereto.

                  Section 8.09 Confidentiality. The Bank agrees to hold all non-
                               ---------------
public information obtained pursuant to the requirements of this Agreement in
accordance with its customary procedure for handling confidential information of
this nature and in accordance with safe and sound banking practices, provided
                                                                     --------
that nothing herein shall prevent any Bank from disclosing such information 
(i) to any other Person if reasonably incidental to the administration of the
Loans, (ii) upon the order of any court or administrative agency, (iii) upon the
request or demand of any regulatory agency or authority, (iv) which had been
publicly disclosed other than as a result of a disclosure by the Bank prohibited
by this Agreement, (v) in connection with any litigation to which the Bank or
its subsidiaries or parent may be a party, (vi) to the extent necessary in
connection with the exercise of any remedy hereunder and (vii) to the Bank's
legal counsel and independent auditors.

                  Section 8.10 Severability; Modification. If any provision
                               --------------------------
hereof is invalid or unenforceable in any jurisdiction, then, to the fullest
extent permitted by law, (i) the other provisions hereof shall remain in full
force and effect in such jurisdiction; and (ii) the invalidity or
unenforceability of any provision hereof in any jurisdiction shall not affect
the validity or enforceability of such provisions in any other jurisdiction. If,
in accordance with an opinion of counsel to the Borrower reasonably satisfactory
to the Bank (and obtained at the Borrower's expense), compliance with any
provision hereof or of any other Loan Document would constitute a "Default" as
defined under the CIGNA Agreements, then said provision of this Agreement shall
be amended to the extent necessary, as set forth in said opinion, to remove said
Default, and the other provisions hereof shall remain in full force and effect
and shall be liberally construed in favor of the Bank in order to carry out the
intentions of the parties hereto as nearly as may be possible.


                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed by their respective authorized officers as of the
day and year first above written.

follows:

1.  PURPOSE

  The Plan is intended to enhance the Company's ability to attract and retain
highly qualified officers, key employees, outside directors and other persons,
and to motivate such officers, key employees, outside directors and other
persons to serve the Company and its affiliates (as defined herein) and to
expend maximum effort to improve the business results and earnings of the
Company, by providing to such officers, key employees, outside directors and
other persons an opportunity to acquire or increase a direct proprietary
interest in the operations and future success of the Company.  To this end, the
Plan provides for the grant of stock options, restricted stock, restricted stock
units, unrestricted stock and stock appreciation rights in accordance with the
terms hereof.  Stock options granted under the Plan may be non-qualified stock
options or incentive stock options, as provided herein, except that stock
options granted to outside directors and all Service Providers shall in all
cases be non-qualified stock options.

Agreements), the following definitions shall apply:

of the Plan as are consistent with the Company's certificate of incorporation,
bylaws and applicable law. The Board shall have full power and authority to take
all actions and to make all determinations required or provided for under the
Plan, any Grant or any Award Agreement, and shall have full power and authority
to take all such other actions and make all such other determinations not
inconsistent with the specific terms and provisions of the Plan that the Board
deems to be necessary or appropriate to the administration of the Plan, any
Grant or any Award Agreement.  All such actions and determinations shall be by
the affirmative vote of a majority of the members of the Board present at a
meeting or by unanimous consent of the Board executed in writing in accordance
with the Company's certificate of incorporation, bylaws and applicable law.  The
interpretation and construction by the Board of any provision of the Plan, any
Grant or any Award Agreement shall be final and conclusive.  As permitted by
law, the Board may delegate its authority under the Plan to a member of the
Board or an executive officer of the Company; provided, however, that, unless
otherwise provided by resolution of the Board, only the Board or the Committee
may make a Grant to an executive officer of the Company and establish the number
of shares of Stock that may be subject to Grants with respect to any fiscal
period.

    3.2.  Committee.

  The Board from time to time may delegate to a Committee such powers and
authorities related to the administration and implementation of the Plan, as set
forth in Section 3.1 hereof and in other applicable provisions of the Plan, as
the Board shall determine, consistent with the Company's certificate of
incorporation, bylaws and applicable law.  In the event that the Plan, any Grant
or any Award 

                                       4
<PAGE>
 
Agreement provides for any action to be taken or determination to be made by the
Board, such action may be taken by or such determination may be made by the
Committee if the power and authority to do so has been delegated to the
Committee by the Board as provided for in this Section 3.2.  Unless otherwise
expressly determined by the Board, any such action or determination by the
Committee shall be final, binding and conclusive. As permitted by law, the
Committee may delegate the authority delegated to it under the Plan to a member
of the Board of Directors or an executive officer of the Company; provided,
however, that, unless otherwise provided by the Board, only the Board or the
Committee may make a Grant to a Reporting Person of the Company and establish
the number of shares of Stock that may be subject to Grants during any fiscal
period.

    3.3.  Grants.

  Subject to the other terms and conditions of the Plan, the Board shall have
full and final authority (i) to designate Grantees, (ii) to determine the types
of Grants to be made to a Grantee, (iii) to determine the number of shares of
Stock to be subject to a Grant, (iv) to establish the terms and conditions of
each Grant, including, but not limited to, the Option Price of any Option, the
nature and duration of any restriction or condition (or provision for lapse
thereof, including lapse relating to a change in control of the Company)
relating to the vesting, exercise, transfer or forfeiture of a Grant or the
shares of Stock subject thereto, and any terms or conditions that may be
necessary to qualify Options as Incentive Stock Options, (v) to prescribe the
form of each Award Agreement evidencing a Grant, (vi) to make Grants alone, in
addition to, in tandem with, or in substitution or exchange for any other Grant
or any other award granted under another plan of the Company or a Subsidiary,
and (vii) to amend, modify or supplement the terms of any outstanding Grant.
Such authority specifically includes the authority, in order to effectuate the
purposes of the Plan but without amending the Plan, to modify Grants to eligible
individuals who are foreign nationals or are individuals who are employed
outside the United States to recognize differences in local law, tax policy or
custom.  As a condition to any subsequent Grant, the Board shall have the right,
at its discretion, to require Grantees to return to the Company any Grants
previously awarded under the Plan.  Subject to the terms and conditions of the
Plan, any such subsequent Grant shall be upon such terms and conditions as are
specified by the Board at the time the subsequent Grant is made.

  The Company may retain the right in an Award Agreement to cause a forfeiture
of the gain realized by a Grantee on account of actions taken by the Grantee in
violation or breach of or in conflict with any non-competition agreement, any
agreement prohibiting solicitation of employees or clients of the Company or any
affiliate thereof or any confidentiality obligation with respect to the Company
or any affiliate thereof or otherwise in competition with the Company, to the
extent specified in such Award Agreement applicable to the Grantee.
Furthermore, the 

                                       5
<PAGE>
 
Company may annul a Grant if the Grantee is an employee of the Company or an
affiliate thereof and is terminated "for cause" as defined in the applicable
Award Agreement. The Board may permit or require the deferral of any award
payment, subject to such rules and procedures as it may establish, which may
include provisions for the payment or crediting of interest or dividend
equivalents, including converting such credits into deferred Stock equivalents.

    3.4.  No Liability.

  No member of the Board or of the Committee shall be liable for any action or
determination made in good faith with respect to the Plan or any Grant or Award
Agreement.

    3.5.  Applicability of Rule 16b-3.

  Those provisions of the Plan that make express reference to Rule 16b-3 under
the Exchange Act shall apply only to Reporting Persons.

4.  STOCK SUBJECT TO THE PLAN

    4.1.  Aggregate Limitation.
    
  Subject to adjustment as provided in Section 18 hereof, the aggregate number
of shares of Stock available for issuance under the Plan pursuant to Options or
other Grants shall be one million four hundred thousand (1,400,000) shares,
which shares may be authorized but unissued shares, treasury shares or issued
and outstanding shares that are purchased in the open market. Any shares of
Stock granted under the Plan which are forfeited to the Company because of the
failure to meet an award contingency or condition shall again be available for
issuance pursuant to new awards granted under the Plan. Any shares of Stock
covered by an award (or portion of an award) granted under the Plan which is
forfeited or canceled, expires or is settled in cash shall be deemed not to have
been issued for purposes of determining the maximum number of shares of Stock
available for issuance under the Plan. If any stock option is exercised by
tendering shares of Stock, either actually or by attestation, to the Company as
full or partial payment in connection with the exercise of a stock option under
the Plan or any prior plan of the Company as hereinabove described, only the
number of shares of Stock issued net of the shares of Stock tendered shall be
deemed issued for purposes of determining the maximum number of shares of Stock
available for issuance under the Plan. Shares of Stock issued under the Plan
through the settlement, assumption or substitution of outstanding awards or
obligations to grant future awards resulting from the acquisition of another
entity shall not reduce the maximum number of shares available for issuance
under the Plan.     

                                       6
<PAGE>
 
    4.2.  Other Plan Limits.
    
  Subject to adjustment as provided in Section 18 hereof, the following
additional limitations are imposed under the Plan. The maximum number of shares
of Stock that may be delivered through stock options intended to be Incentive
Stock Options shall be one million four hundred thousand (1,400,000) shares.
Subject to adjustment as provided in Section 18 hereof, the maximum number of
shares of Stock that may be issued in conjunction with awards granted pursuant
to Sections 12 and 14 hereof shall be two hundred fifty thousand (250,000);
provided, however, that shares issued in satisfaction of other compensation
obligations of the Company shall not count against this maximum number.     

    4.3.  Payment Shares.

  Subject to the overall limitation on the number of shares of Stock that may be
delivered under the Plan, the Board may use available shares of Stock as the
form of payment for compensation, grants or rights earned or due under any other
compensation plans or arrangements of the Company, including the plan of any
entity acquired by the Company, and such payment shares shall not count against
the limitation on the maximum number of shares specified in Section 4.2.

    4.4.  Application of Aggregate Limitation.

  The Board may adopt reasonable counting procedures to ensure appropriate
counting, avoid double counting (as, for example, in the case of tandem or
substitute awards) and make adjustments if the number of shares of Stock
actually delivered differs from the number of shares of Stock previously counted
in connection with a Grant.

    4.5.  Per-Grantee Limitation.

  During any time when the Company has a class of equity security registered
under Section 12 of the Exchange Act:

     (i)   no person eligible for a Grant under Section 6 hereof may be awarded
     Options for purposes of the Plan exercisable for greater than five hundred
     thousand (500,000) shares of Stock (subject to adjustment as provided in
     Section 18 hereof);
    
     (ii)   the maximum number of shares of Unrestricted Stock and Restricted
     Stock that may be awarded under the Plan (including for this purpose any
     shares of Stock represented by Restricted Stock Units) to any person
     eligible for a Grant under Sections 12 and 14 hereof if such Grant is
     intended to qualify as performance-based under Code Section 162(m) is two
     hundred fifty      

                                       7
<PAGE>
 
     thousand (250,000) for purposes of the Plan (subject to adjustment as
     provided in Section 18 hereof);

     (iii)   the maximum number of shares of Stock that may be the subject of
     SARs awarded to any Grantee under Section 13 hereof is two hundred fifty
     thousand (250,000) for purposes of the Plan (subject to adjustment as
     provided in Section 18 hereof).

5.  EFFECTIVE DATE AND TERM OF THE PLAN

    5.1.  Effective Date.

  The Plan shall be effective as of the Effective Date, subject to approval of
the Plan by the stockholders of the Company, within one year before or after the
date upon which the Plan was adopted by the Board.  Such approval shall be by a
majority of the votes cast on the proposal at a meeting of stockholders,
provided that a quorum is present.  Upon approval of the Plan by the
stockholders of the Company as set forth above, all Grants made under the Plan
on or after the Effective Date shall be fully effective as if the stockholders
of the Company had approved the Plan on the Effective Date.  If the stockholders
fail to approve the Plan within the time period set forth above, any Grants made
hereunder shall be null and void and of no effect.

Plan to any employee of the Company or any Subsidiary, including any such
employee who is an officer or director of the Company, to an Outside Director,
to a Service Provider or employee of a Service Provider providing, or who has
provided, services to the Company or any Subsidiary, and to any other individual
whose participation in the Plan is determined by the Board to be in the best
interests of the Company, as the Board shall determine and designate from time
to time.

                                       8
<PAGE>
 
    6.2.  Multiple Grants.

  An eligible person may receive more than one Grant, subject to such
restrictions as are provided herein.

7.  LIMITATIONS ON GRANTS OF INCENTIVE STOCK OPTIONS

  An Option shall constitute an Incentive Stock Option only (i) if the Grantee
of such Option is an employee of the Company or any Subsidiary of the Company;
(ii) to the extent specifically provided in the related Award Agreement; and
(iii) to the extent that the aggregate Fair Market Value (determined at the time
the Option is granted) of the shares of Stock with respect to which all
Incentive Stock Options held by such Grantee become exercisable for the first
time during any calendar year (under the Plan and all other plans of the
Grantee's employer and its affiliates) does not exceed $100,000.  This
limitation shall be applied by taking Options into account in the order in which
they were granted.

8.  AWARD AGREEMENT

  Each Grant pursuant to the Plan shall be evidenced by an Award Agreement, in
such form or forms as the Board shall from time to time determine.  Award
Agreements issued from time to time or at the same time need not contain similar
provisions but shall be consistent with the terms of the Plan.  Each Award
Agreement evidencing a Grant of Options shall specify whether such Options are
intended to be non-qualified stock options or Incentive Stock Options, and in
the absence of such specification such options shall be deemed non-qualified
stock options.

9.  OPTION PRICE

  The Option Price of each Option shall be no less than the Fair Market Value of
a share of Stock on the date of grant and stated in the Award Agreement
evidencing such Option; provided, however, that in the event that a Grantee
would otherwise be ineligible to receive an Incentive Stock Option by reason of
the provisions of Sections 422(b)(6) and 424(d) of the Code (relating to
ownership of more than ten percent (10%) of the Company's outstanding shares of
Stock), the Option Price of an Option granted to such Grantee that is intended
to be an Incentive Stock Option shall be not less than one hundred ten percent
(110%) of the Fair Market Value of a share of Stock on the Grant Date.  In no
case shall the Option Price of any Option be less than the par value of a share
of Stock.

10.  VESTING, TERM AND EXERCISE OF OPTIONS

     10.1.  Vesting and Option Period.

  Subject to Sections 10.2 and 18 hereof, each Option granted under the Plan
shall become exercisable at such times and under such conditions as shall be
determined by the Board and stated in the Award Agreement.  For purposes of this
Section 10.1, fractional numbers of shares of Stock subject to an Option shall

shares of Stock thereunder shall cease, upon the expiration of ten years from
the date such Option is granted, or under such circumstances and on such date
prior thereto as is set forth in the Plan or as may be fixed by the Board and
thereafter stated in the Award Agreement relating to such Option; provided,
however, that in the event that the Grantee would otherwise be ineligible to
receive an Incentive Stock Option by reason of the provisions of Sections
422(b)(6) and 424(d) of the Code (relating to ownership of more than ten percent
(10%) of the outstanding shares of Stock), an Option granted to such Grantee
that is intended to be an Incentive Stock Option shall not be exercisable after
the expiration of five years from its date of grant.

     10.3.  Acceleration.

  Any limitation on the exercise of an Option contained in any Award Agreement
may be rescinded, modified or waived by the Board, in its sole discretion, at
any time and from time to time after the Grant Date of such Option, so as to
accelerate the time at which the Option may be exercised.

     10.4.  Termination of Employment or Other Relationship for a Reason Other
            than Death or Disability.

  Unless otherwise provided by the Board, upon the termination of a Grantee's
employment or other relationship with the Company and its Subsidiaries other
than by reason of death, "permanent and total disability" (within the meaning
of Section 22(e)(3) of the Code) or retirement, any Option or portion thereof
held by such Grantee that has not vested in accordance with the provisions of
Section 10.1 hereof shall terminate immediately, and any Option or portion
thereof that has vested in accordance with the provisions of Section 10.1 hereof
but has not been exercised shall terminate at the close of business on the 90th
day following the 

                                       10
<PAGE>
 
Grantee's termination of employment or other relationship (or, if such 90th day
is a Saturday, Sunday or holiday, at the close of business on the next preceding
day that is not a Saturday, Sunday or holiday). Upon termination of an Option or
portion thereof, the Grantee shall have no further right to purchase shares of
Stock pursuant to such Option or portion thereof. Whether a leave of absence or
leave on military or government service shall constitute a termination of
employment or other relationship for purposes of the Plan shall be determined by
the Board, whose determination shall be final and conclusive. For purposes of
the Plan, a termination of employment, service or other relationship shall not
be deemed to occur if the Grantee is immediately thereafter employed with the
Company, a Subsidiary or a Service Provider, or is engaged as a Service Provider
or an Outside Director. Whether a termination of a Grantee's employment or other
relationship with the Company and its Subsidiaries shall have occurred shall be
determined by the Board, whose determination shall be final and conclusive.

     10.5.  Rights in the Event of Death.

  Unless otherwise provided by the Board, if a Grantee dies while employed by or
providing services to the Company, all Options granted to such Grantee that have
not previously terminated shall fully vest on the date of death, and the
executors or administrators or legatees or distributees of such Grantee's estate
shall have the right, at any time within one year after the date of such
Grantee's death and prior to termination of the Option pursuant to Section 10.2
hereof, to exercise any Option held by such Grantee at the date of such
Grantee's death.

     10.6.  Rights in the Event of Disability.

  Unless otherwise provided by the Board, if a Grantee's employment or other
relationship with the Company is terminated by reason of the "permanent and
total disability" (within the meaning of Section 22(e)(3) of the Code) of such
Grantee, such Grantee's Options that have not previously terminated shall fully
vest, and shall be exercisable for a period of one year after such termination
of employment or other relationship, subject to earlier termination of the
Option as provided in Section 10.2 hereof.  Whether a termination of employment
or other relationship is considered to be by reason of "permanent and total
disability" for purposes of the Plan shall be determined by the Board, whose
determination shall be final and conclusive.

     10.7.  Rights in the Event of Retirement.

  Unless otherwise provided by the Board, if a Grantee retires under the terms
of any Company retirement plan applicable to the Grantee or as determined by the
Board, the Grantee shall be considered retired and all Options granted to such
Grantee that have not previously terminated shall fully vest on the date of

                                       11
<PAGE>
 
retirement, and the Grantee shall have the right, at any time within three years
after the date of such Grantee's retirement and prior to termination of the
Option pursuant to Section 10.2 hereof, to exercise any Option held by such
Grantee at the date of such Grantee's retirement.

     10.8.  Limitations on Exercise of Option.

  Notwithstanding any other provision of the Plan, in no event may any Option be
exercised, in whole or in part, prior to the date the Plan is approved by the
stockholders of the Company as provided herein, or after ten years following the
date upon which the Option is granted, or after the occurrence of an event
referred to in Section 18 hereof which results in termination of the Option.

     10.9.  Method of Exercise.

  An Option that is exercisable may be exercised by the Grantee's delivery to
the Company of written notice of exercise on any business day, at the Company's
principal office, addressed to the attention of the Board.  Such notice shall
specify the number of shares of Stock with respect to which the Option is being
exercised and shall be accompanied by payment in full of the Option Price of the
shares of Stock for which the Option is being exercised.  The minimum number of
shares of Stock with respect to which an Option may be exercised, in whole or in
part, at any time shall be the lesser of (i) 100 shares or such lesser number
set forth in the applicable Award Agreement and (ii) the maximum number of
shares of Stock available for purchase under the Option at the time of exercise.
Payment of the Option Price for the shares of Stock purchased pursuant to the
exercise of an Option shall be made (i) in cash or in cash equivalents
acceptable to the Company; (ii) to the extent permitted by law and at the
Board's discretion, through the actual or constructive tender to the Company of
shares of Stock, which shares of Stock, if acquired from the Company, shall have
been held for at least six months prior to such tender and which shall be
valued, for purposes of determining the extent to which the Option Price has
been paid thereby, at their Fair Market Value on the date of exercise; or (iii)
to the extent permitted by law and at the Board's discretion, by a combination
of the methods described in clauses (i) and (ii).  The Board may provide, by
inclusion of appropriate language in an Award Agreement, that payment in full of
the Option Price need not accompany the written notice of exercise, provided
that the notice is accompanied by delivery of an unconditional and irrevocable
undertaking by a licensed broker acceptable to the Company as the agent for the
individual exercising the Option to deliver promptly to the Company sufficient
funds to pay the Option Price and directs that the certificate or certificates
for the shares of Stock for which the Option is exercised be delivered to a
licensed broker acceptable to the Company as the agent for the individual
exercising the Option and, at the time such certificate or certificates are
delivered, the broker tenders to the Company cash (or cash equivalents
acceptable to the 

                                       12
<PAGE>
 
Company) equal to the Option Price for the shares of Stock purchased pursuant to
the exercise of the Option plus the amount (if any) of federal or other taxes
which the Company may in its judgment be required to withhold with respect to
the exercise of the Option. An attempt to exercise any Option granted hereunder
other than as set forth above shall be invalid and of no force and effect.

     10.10. Rights as a Stockholder; Dividend Equivalents.

  Unless otherwise stated in the applicable Award Agreement, an individual
holding or exercising an Option shall have none of the rights of a stockholder
(for example, the right to receive cash or dividend payments or distributions
attributable to the subject shares of Stock or to direct the voting of the
subject shares of Stock) until the shares of Stock covered thereby are fully
paid and issued to such individual.  Except as provided in Section 18 hereof, no
adjustment shall be made for dividends, distributions or other rights for which
the record date is prior to the date of such issuance.  However, the Board may,
on such conditions as it deems appropriate, provide that a Grantee will receive
a benefit in lieu of cash dividends that would have been payable on any or all
shares of Stock subject to the Grant if such shares of Stock had been
outstanding.  Without limitation, the Board may provide for payment to the
Grantee of amounts representing such dividends, either currently or in the
future, or for the investment of such amounts on behalf of the Grantee.

     10.11. Delivery of Stock Certificates.

  Promptly after the exercise of an Option by a Grantee and the payment in full
of the Option Price, such Grantee shall be entitled to the issuance of a Stock
certificate or certificates evidencing such Grantee's ownership of the shares of
Stock subject to the Option.

11.  TRANSFERABILITY OF OPTIONS

     11.1.  General Rule

  Except as provided in Section 11.2 hereof, during the lifetime of a Grantee,
only the Grantee (or, in the event of legal incapacity or incompetency, the
Grantee's guardian or legal representative) may exercise an Option.  Except as
provided in Section 11.2 hereof, no Option shall be assignable or transferable
by the Grantee to whom it is granted, other than by will or the laws of descent
and distribution.

     11.2.  Family Transfers.

  To the extent permitted by the Board and under such rules and conditions as
imposed by the Board, a Grantee may transfer all or part of an Option that is
not an 

                                       13
<PAGE>
 
Incentive Stock Option to (i) any Immediate Family Member, (ii) a trust
or trusts for the exclusive benefit of any Immediate Family Member or (iii) a
partnership or limited liability company in which Immediate Family Members are
the only partners or members, provided that (x) there may be no consideration
for any such transfer, and (y) subsequent transfers of transferred Options or
transfers of an interest in a trust, partnership, or limited liability company
to which an Option has been transferred are prohibited except those in
accordance with this Section 11.2 or by will or the laws of descent and
distribution.  Following such transfer, any such Option shall continue to be
subject to the same terms and conditions as were applicable immediately prior to
the transfer, provided that, for purposes of this Section 11.2, the term
"Grantee" shall be deemed to refer to the transferee.  The events of
termination of employment or other relationship referred to in Section 10.4
hereof shall continue to be applied with respect to the original Grantee,
following which the Option shall be exercisable by the transferee only to the
extent and for the periods specified in Section 10.4, 10.5, 10.6 or 10.7 hereof.

12.  RESTRICTED STOCK
     
     12.1.  Grant of Restricted Stock or Restricted Stock Units.

     The Board from time to time may grant Restricted Stock or Restricted Stock
Units to persons eligible to receive Grants under Section 6 hereof, subject to
such restrictions, conditions and other terms as the Board may determine.

     12.2.  Restrictions.

     At the time a Grant of Restricted Stock or Restricted Stock Units is made,
the Board shall establish a period of time (the "Restricted Period")
applicable to such Restricted Stock or Restricted Stock Units. Unless otherwise
determined by the Board, unless the Grant is being made in consideration of
compensation due under another plan, or unless vesting is subject to
performance, the Restricted Period will be a minimum of three years. Each Grant
of Restricted Stock or Restricted Stock Units may be subject to a different
Restricted Period. At the time a Grant of Restricted Stock or Restricted Stock
Units is made, the Board may, in its sole discretion, prescribe restrictions in
addition to or other than the expiration of the Restricted Period, including the
satisfaction of corporate or individual performance objectives, which may be
applicable to all or any portion of the Restricted Stock or Restricted Stock
Units. Such performance objectives shall be established in writing by the Board
by not later than the 90th day of the period of service to which such
performance objectives relate and while the outcome is substantially uncertain.
Performance objectives may be stated either on an absolute or relative basis and
may be based on any of the following criteria: earnings per share, total
stockholder return, operating earnings, growth in assets, return on equity,
return on capital, market share, stock price, net income, cash flow, sales
growth (in general, by type of 

                                       14
<PAGE>
 
product and by type of customer), retained earnings, completion of acquisitions,
completion of divestitures and asset sales, cost or expense reductions,
introduction or conversion of product brands and achievement of specified
management information systems objectives. Performance objectives may include
positive results, maintaining the status quo or limiting economic losses.
Subject to the fifth sentence of this Section 12.2, the Board also may, in its
sole discretion, shorten or terminate the Restricted Period or waive any other
restrictions applicable to all or a portion of the Restricted Stock or
Restricted Stock Units. Neither Restricted Stock nor Restricted Stock Units may
be sold, transferred, assigned, pledged or otherwise encumbered or disposed of
during the Restricted Period or prior to the satisfaction of any other
restrictions prescribed by the Board with respect to such Restricted Stock or
Restricted Stock Units.

     12.3.  Restricted Stock Certificates.

     The Company shall issue, in the name of each Grantee to whom Restricted
Stock has been granted, Stock certificates representing the total number of
shares of Restricted Stock granted to the Grantee, as soon as reasonably
practicable after the Grant Date.  The Board may provide in an Award Agreement
that either (i)  the Secretary of the Company shall hold such certificates for
the Grantee's benefit until such time as the Restricted Stock is forfeited to
the Company or the restrictions lapse, or (ii)  such certificates shall be
delivered to the Grantee, provided, however, that such certificates shall bear a
legend or legends complying with the applicable securities laws and regulations
and making appropriate reference to the restrictions imposed under the Plan and
the Award Agreement.

     12.4.  Rights of Holders of Restricted Stock.

     Unless the Board otherwise provides in an Award Agreement, holders of
Restricted Stock shall have the right to vote such shares of Stock and the right
to receive any dividends declared or paid with respect to such shares of Stock.
The Board may provide that any dividends paid on Restricted Stock must be
reinvested in shares of Stock, which may or may not be subject to the same
vesting conditions and restrictions applicable to such Restricted Stock.  All
distributions, if any, received by a Grantee with respect to Restricted Stock as
a result of any stock split, stock dividend, combination of shares or other
similar transaction shall be subject to the restrictions applicable to the
original Grant.

     12.5.  Rights of Holders of Restricted Stock Units.

     Unless the Board otherwise provides in an Award Agreement, holders of
Restricted Stock Units shall have no rights as stockholders of the Company.  The
Board may provide in an Award Agreement evidencing a Grant of Restricted Stock
Units that the holder of such Restricted Stock Units shall be entitled to
receive, 

                                       15
<PAGE>
 
upon the Company's payment of a cash dividend on its outstanding shares
of Stock, a cash payment for each Restricted Stock Unit held equal to the per-
share dividend paid on the shares of Stock.  Such Award Agreement may also
provide that such cash payment will be deemed reinvested in additional
Restricted Stock Units at a price per unit equal to the Fair Market Value of a
share on the date that such dividend is paid.

     12.6.  Termination of Employment or Other Relationship for a Reason Other
than Death or Disability.

     Unless otherwise provided by the Board, upon the termination of a Grantee's
employment or other relationship with the Company and its Subsidiaries, in
either case other than, in the case of individuals, by reason of death or
"permanent and total disability" (within the meaning of Section 22(e)(3) of
the Code), any Restricted Stock or Restricted Stock Units held by such Grantee
that have not vested, or with respect to which all applicable restrictions and
conditions have not lapsed, shall immediately be deemed forfeited.  Upon
forfeiture of Restricted Stock or Restricted Stock Units, the Grantee shall have
no further rights with respect to such Grant, including, but not limited to, any
right to vote Restricted Stock or any right to receive dividends with respect to
Restricted Stock or Restricted Stock Units.  Whether a leave of absence or leave
on military or government service shall constitute a termination of employment
or other relationship for purposes of the Plan shall be determined by the Board,
whose determination shall be final and conclusive.  For purposes of the Plan, a
termination of employment, service or other relationship shall not be deemed to
occur if the Grantee is immediately thereafter employed with the Company or any
other Service Provider, or is engaged as a Service Provider or an Outside
Director.  Whether a termination of a Grantee's employment or other relationship
with the Company and its Subsidiaries shall have occurred shall be determined by
the Board, whose determination shall be final and conclusive.

     12.7.  Rights in the Event of Death.

     Unless otherwise provided by the Board, if a Grantee dies while employed by
the Company or a Service Provider, or while serving as a Service Provider, all
Restricted Stock or Restricted Stock Units granted to such Grantee shall fully
vest on the date of death unless the Board provided otherwise in the Award
Agreement relating to such Restricted Stock or Restricted Stock Units.  Upon
such vesting, the shares of Stock represented thereby shall be deliverable in
accordance with the terms of the Plan to the executors, administrators, legatees
or distributees of the Grantee's estate.

                                       16
<PAGE>
 
     12.8.   Rights in the Event of Disability.

     Unless otherwise provided by the Board, if a Grantee's employment or other
relationship with the Company or a Service Provider, or service as a Service
Provider, is terminated by reason of the "permanent and total disability"
(within the meaning of Section 22(e)(3) of the Code) of such Grantee, such
Grantee's then unvested Restricted Stock or Restricted Stock Units shall be
fully vested.  Whether a termination of employment, service or other
relationship is to be considered by reason of "permanent and total disability"
for purposes of the Plan shall be determined by the Board, whose determination
shall be final and conclusive.

     12.9.  Delivery of Shares and Payment Therefor.

     Upon the expiration or termination of the Restricted Period and the
satisfaction of any other conditions prescribed by the Board, the restrictions
applicable to Restricted Stock or Restricted Stock Units shall lapse, and,
unless otherwise provided in the Award Agreement, upon payment by the Grantee to
the Company, in cash or by check, of the greater of (i) the aggregate par value
of the shares of Stock represented by such Restricted Stock or Restricted Stock
Units or (ii) the purchase price, if any, specified in the Award Agreement
relating to such Restricted Stock or Restricted Stock Units, a certificate for
such shares shall be delivered, free of all such restrictions, to the Grantee or
the Grantee's beneficiary or estate, as the case may be.

13.  STOCK APPRECIATION RIGHTS

     13.1.  Grant of Stock Appreciation Rights.

     The Board may from time to time grant SARs to persons eligible to receive
grants under Section 6 hereof, subject to the provisions of this Section 13 and
to such restrictions, conditions and other terms as the Board may determine.

     13.2.  Nature of a Stock Appreciation Right.

     An SAR shall confer on the Grantee a right to receive, upon exercise
thereof, the excess of (A) the Fair Market Value of one share of Stock on the
date of exercise over (B) the grant price of the SAR, as determined by the
Board. Unless the Board provides otherwise in the Award Agreement, the grant
price of an SAR shall not be less than the Fair Market Value of a share of Stock
on the Grant Date.

     13.3.  Terms and Conditions Governing SARs.

     The Board shall determine at the Grant Date or thereafter the time or times
at which and the circumstances under which an SAR may be exercised in whole or
in 

                                       17
<PAGE>
 
part (including exercise based on achievement of performance objectives or
future service requirements), the time or times at which and the circumstances
under which an SAR shall cease to be exercisable, the method of exercise, the
method of settlement, form of consideration payable in settlement, whether or
not an SAR shall be in tandem or in combination with any other Grant, and any
other terms and conditions of any SAR.

14.  UNRESTRICTED STOCK

     The Board may, in its sole discretion, grant Stock (or sell Stock at par
value or such other higher purchase price determined by the Board) free of
restrictions other than those required under federal or state securities laws
("Unrestricted Stock") to persons eligible to receive grants under Section 6
hereof. Unrestricted Stock may be granted or sold as described in the preceding
sentence in respect of past services or other valid consideration, or in lieu of
any cash compensation due to such Grantee.

15.  PARACHUTE LIMITATIONS

     If the Grantee is a "disqualified individual" (as defined in Section
280G(c) of the Code), any Option, Restricted Stock, Restricted Stock Unit or SAR
and any other right to receive any payment or benefit under the Plan shall not
vest or become exercisable (i) to the extent that the right to vest or any other
right to any payment or benefit, taking into account all other rights, payments
or benefits to or for the Grantee, would cause any payment or benefit to the
Grantee under the Plan to be considered a "parachute payment" within the
meaning of Section 280G(b)(2) of the Code as then in effect (a "Parachute
Payment") and (ii) if, as a result of receiving a Parachute Payment, the
aggregate after-tax amounts received by the Grantee from the Company under any
Award Agreements, the Plan, and all other rights, payments or benefits to or for
the Grantee would be less than the maximum after-tax amount that could be
received by the Grantee without causing the payment or benefit to be considered
a Parachute Payment. In the event that, but for the provisions of this Section
15, the Grantee would be considered to have received a Parachute Payment under
any Award Agreements that would have the effect of decreasing the after-tax
amount received by the Grantee as described in clause (ii) of the preceding
sentence, then the Grantee shall have the right, in the Grantee's sole
discretion, to designate any rights, payments or benefits under any Award
Agreements, the Plan, any other agreements and any benefit arrangements to be
reduced or eliminated so as to avoid having the payment or benefit to the
Grantee under any Award Agreements be deemed to be a Parachute Payment.

                                       18
<PAGE>
 
16.  REQUIREMENTS OF LAW

     16.1.  General.

     The Company shall not be required to sell or issue any shares of Stock
under any Grant if the sale or issuance of such shares of Stock would constitute
a violation by the Grantee, any other person exercising a right emanating from
such Grant, or the Company of any provision of any law or regulation of any
governmental authority, including, without limitation, any federal or state
securities laws or regulations. If at any time the Company shall determine, in
its discretion, that the listing, registration or qualification of any shares of
Stock subject to a Grant upon any securities exchange or under any governmental
regulatory body is necessary or desirable as a condition of, or in connection
with, the issuance or purchase of shares of Stock hereunder, no shares of Stock
may be issued or sold to the Grantee or any other person exercising a right
emanating from such Grant unless such listing, registration, qualification,
consent or approval shall have been effected or obtained free of any conditions
not acceptable to the Company, and any delay caused thereby shall in no way
affect the date of termination of the Grant. Without limiting the generality of
the foregoing, upon the exercise of any Option or any SAR that may be settled in
shares of Stock or the delivery of any Restricted Stock or shares of Stock
underlying Restricted Stock Units, unless a registration statement under the
Securities Act is in effect with respect to the shares of Stock covered by such
Grant, the Company shall not be required to sell or issue such shares of Stock
unless the Board has received evidence satisfactory to it that the Grantee or
any other person exercising a right emanating from such Grant may acquire such
shares of Stock pursuant to an exemption from registration under the Securities
Act. Any such determination by the Board shall be final, binding and conclusive.
The Company may, but shall in no event be obligated to, register any securities
covered hereby pursuant to the Securities Act. The Company shall not be
obligated to take any affirmative action in order to cause the exercise of an
Option or an SAR or the issuance of shares of Stock pursuant to the Plan to
comply with any law or regulation of any governmental authority. As to any
jurisdiction that expressly imposes the requirement that an Option (or SAR that
may be settled in shares of Stock) shall not be exercisable until the shares of
Stock covered by such Option (or SAR) are registered or are exempt from
registration, the exercise of such Option (or SAR) under circumstances in which
the laws of such jurisdiction apply shall be deemed conditioned upon the
effectiveness of such registration or the availability of such an exemption.

     16.2.  Rule 16b-3.

     During any time when the Company has a class of equity security registered
under Section 12 of the Exchange Act, it is the intent of the Company that
Grants pursuant to the Plan and the exercise of Options and SARs granted
hereunder will 

                                       19
<PAGE>
 
qualify for the exemption provided by Rule 16b-3 under the Exchange Act. To the
extent that any provision of the Plan or action by the Board does not comply
with the requirements of Rule 16b-3, such provision or action shall be deemed
inoperative to the extent permitted by law and deemed advisable by the Board,
and shall not affect the validity of the Plan. In the event that Rule 16b-3 is
revised or replaced, the Board may exercise its discretion to modify the Plan in
any respect necessary to satisfy the requirements of, or to take advantage of
any features of, the revised exemption or its replacement.

17.  AMENDMENT AND TERMINATION OF THE PLAN

     The Board may, at any time and from time to time, amend, suspend or
terminate the Plan as to any shares of Stock as to which Grants have not been
made. Except as permitted under this Section 17 or Section 18 hereof, no
amendment, suspension or termination of the Plan shall, without the consent of
the Grantee, alter or impair rights or obligations under any Grant theretofore
awarded under the Plan.

18.  EFFECT OF CHANGES IN CAPITALIZATION

     18.1.  Changes in Stock.

     Subject to Section 18.2 hereof, in the event of any merger, reorganization,
consolidation, recapitalization, separation, liquidation, stock dividend, spin-
off, split-up, share combination or other change in the corporate structure of
the Company affecting the shares of Stock, (a) such adjustment may be made in
the number and class of shares which may be delivered under Section 4 hereof and
the Grant limits under Section 4 hereof, and in the number and class of or price
of shares subject to outstanding Grants as may be determined to be appropriate
and equitable by the Board, in its sole discretion, to prevent dilution or
enlargement of existing rights; and (b) the Board or, if another legal entity
assumes the obligations of the Company hereunder, the board of directors,
compensation committee or similar body of such other legal entity shall either
(i) make appropriate provision for the protection of outstanding Grants by the
substitution on an equitable basis of appropriate equity interests or awards
similar to the Grants, provided that the substitution neither enlarges nor
diminishes the value and rights under the Grants, or (ii) upon written notice to
the Grantees, provide that Grants shall be exercised distributed, canceled or
exchanged for value pursuant to such terms and conditions (including the waiver
of any existing terms or conditions) as shall be specified in the notice.  Any
adjustment of an Incentive Stock Option under this Section 18.1 shall be made in
such a manner so as not to constitute a "modification" within the meaning of
Section 424(h)(3) of the Code.  The conversion of any convertible securities of
the Company shall not be treated as a change in the corporate structure of the
Company affecting the shares of Stock.  Subject to any contrary language in an
Award Agreement evidencing a Grant of Restricted Stock, any 

                                       20
<PAGE>
 
restrictions applicable to such Restricted Stock shall apply as well to any
replacement shares received by the Grantee as a result of the merger,
reorganization or other transaction referred to in this Section 18.1.

     18.2.  Reorganization, Sale of Assets or Sale of Stock.

     Upon the dissolution or liquidation of the Company or upon a merger,
consolidation or reorganization of the Company with one or more other entities
in which the Company is not the surviving entity, or upon a sale of
substantially all of the assets of the Company to another entity, or upon any
transaction (including, without limitation, a merger or reorganization in which
the Company is the surviving entity) approved by the Board that results in any
person or entity (or person or entities acting as a group or otherwise in
concert) owning eighty percent (80%) or more of the combined voting power of all
classes of securities of the Company, (i) all outstanding Restricted Stock and
Restricted Stock Units shall be deemed to have vested, and all restrictions and
conditions applicable to such Restricted Stock and Restricted Stock Units shall
be deemed to have lapsed, immediately prior to the occurrence of such
transaction, and (ii) all Options and SARs outstanding hereunder shall become
immediately exercisable for a period of fifteen days immediately prior to the
scheduled consummation of such transaction.  Any exercise of an Option or SAR
during such fifteen-day period shall be conditioned upon the consummation of the
transaction and shall be effective only immediately before the consummation of
the transaction.

     This Section 18.2 shall not apply to any transaction to the extent that (A)
provision is made in writing in connection with such transaction for the
continuation of the Plan or the assumption of the Options, SARs, Restricted
Stock and Restricted Stock Units theretofore granted, or for the substitution
for such Options, SARs, Restricted Stock and Restricted Stock Units of new
options, stock appreciation rights, restricted stock and restricted stock units
covering the stock of a successor entity, or a parent or subsidiary thereof,
with appropriate adjustments as to the number and kinds of shares or units and
exercise prices, in which event the Plan and Options, SARs, Restricted Stock and
Restricted Stock Units theretofore granted shall continue in the manner and
under the terms so provided or (B) a majority of the full Board determines that
such transaction shall not trigger application of the provisions of this Section
18.2 subject to Section 26 hereof and limited by any "change in control"
provision in any employment agreement or Award Agreement applicable to the
Grantee.  Upon consummation of any such transaction, the Plan and all
outstanding but unexercised Options and SARs shall terminate, except to the
extent provision is made in writing in connection with such transaction for the
continuation of the Plan or the assumption of such Options and SARs theretofore
granted, or for the substitution for such Options and SARs of new options and
stock appreciation rights covering the shares of a successor entity, or a parent
or subsidiary thereof, with appropriate adjustments as to the number and 

                                       21
<PAGE>
 
kinds of shares or units and exercise prices, in which event the Plan and
Options and SARs theretofore granted shall continue in the manner and under the
terms so provided. The Board shall send written notice of an event that will
result in such a termination to all individuals who hold Options and SARs not
later than the time at which the Company gives notice thereof to its
stockholders.

     18.3.  Adjustments.

     Adjustments under this Section 18 related to shares of Stock or securities
of the Company shall be made by the Board, whose determination in that respect
shall be final and conclusive. No fractional shares or other securities shall be
issued pursuant to any such adjustment, and any fractions resulting from any
such adjustment shall be eliminated in each case by rounding downward to the
nearest whole share.

     18.4.  No Limitations on Company.

     The making of Grants pursuant to the Plan shall not affect or limit in any
way the right or power of the Company to make adjustments, reclassifications,
reorganizations or changes of its capital or business structure or to merge,
consolidate, dissolve or liquidate, or to sell or transfer all or any part of
its business or assets.

19.  DISCLAIMER OF RIGHTS

     No provision in the Plan or in any Grant or Award Agreement shall be
construed to confer upon any individual the right to remain in the employ or
service of the Company or any affiliate thereof, or to interfere in any way with
any contractual or other right or authority of the Company or Service Provider
either to increase or decrease the compensation or other payments to any
individual at any time, or to terminate any employment or other relationship
between any individual and the Company or any affiliate thereof. In addition,
notwithstanding anything contained in the Plan to the contrary, unless otherwise
stated in the applicable Award Agreement or employment agreement, no Grant
awarded under the Plan shall be affected by any change of duties or position of
the Grantee, so long as such Grantee continues to be a director, officer,
consultant or employee of the Company. The obligation of the Company to pay any
benefits pursuant to the Plan shall be interpreted as a contractual obligation
to pay only those amounts described herein, in the manner and under the
conditions prescribed herein. The Plan shall in no way be interpreted to require
the Company to transfer any amounts to a third party trustee or otherwise hold
any amounts in trust or escrow for payment to any participant or beneficiary
under the terms of the Plan. No Grantee shall have any of the rights of a
stockholder with respect to the shares of Stock subject to an Option 

                                       22
<PAGE>
 
or SAR except to the extent such shares of Stock shall have been issued upon the
exercise of the Option or SAR.

20.  NONEXCLUSIVITY OF THE PLAN

     Neither the adoption of the Plan nor the submission of the Plan to the
stockholders of the Company for approval shall be construed as creating any
limitations upon the right and authority of the Board to adopt such other
incentive compensation arrangements (which arrangements may be applicable either
generally to a class or classes of individuals or specifically to a particular
individual or particular individuals) as the Board in its discretion determines
desirable, including, without limitation, the granting of Stock options
otherwise than under the Plan.

21.  WITHHOLDING TAXES

     The Company or a Subsidiary, as the case may be, shall have the right to
deduct from payments of any kind otherwise due to a Grantee any federal, state
or local taxes of any kind required by law to be withheld with respect to the
vesting of or other lapse of restrictions applicable to Restricted Stock or
Restricted Stock Units or upon the exercise of an Option or SAR or the grant of
Unrestricted Stock.  At the time of such vesting, lapse or exercise, the Grantee
shall pay to the Company or the Subsidiary, as the case may be, any amount that
the Company or the Subsidiary may reasonably determine to be necessary to
satisfy such withholding obligation.  Subject to the prior approval of the
Company or the Subsidiary, which may be withheld by the Company or the
Subsidiary, as the case may be, in its sole discretion, the Grantee may elect to
satisfy such obligations, in whole or in part, (i) by causing the Company or the
Subsidiary to withhold shares of Stock otherwise issuable to the Grantee or (ii)
by delivering to the Company or the Subsidiary shares of Stock already owned by
the Grantee.  The shares of Stock so delivered or withheld shall have an
aggregate Fair Market Value equal to such withholding obligations.  The Fair
Market Value of the shares of Stock used to satisfy such withholding obligation
shall be determined by the Company or the Subsidiary as of the date that the
amount of tax to be withheld is to be determined.  A Grantee who has made an
election pursuant to this Section 21 may satisfy such Grantee's withholding
obligation only with shares of Stock that are not subject to any repurchase,
forfeiture, unfulfilled vesting or other similar requirement.

22.  CAPTIONS

     The use of captions in the Plan or any Award Agreement is for convenience
of reference only and shall not affect the meaning of any provision of the Plan
or such Award Agreement.

                                       23
<PAGE>
 
23.  OTHER PROVISIONS

     Each Grant awarded under the Plan may contain such other terms and
conditions not inconsistent with the Plan as may be determined by the Board, in
its sole discretion.

24.  NUMBER AND GENDER

     With respect to words used in this Plan, the singular form shall include
the plural form and, the masculine gender shall include the feminine gender, as
the context requires.

25.  SEVERABILITY

     If any provision of the Plan or any Award Agreement shall be finally
determined to be illegal or unenforceable by any court of law in any
jurisdiction, the remaining provisions hereof and thereof shall be severable and
enforceable in accordance with their terms, and all provisions shall remain
enforceable in any other jurisdiction.

26.  POOLING

     Notwithstanding anything in the Plan to the contrary, if any action
described in the Plan would cause a transaction to be ineligible for pooling of
interests accounting that would, but for the action under the Plan, be eligible
for such accounting treatment, the Board shall modify or adjust such action so
that the transaction will be eligible for pooling of interests accounting, if
the Company intends to use such accounting in the transaction. Such modification
or adjustment may include payment of cash or issuance to a Grantee of shares of
Stock of equivalent Fair Market Value.

27.  GOVERNING LAW

     The validity and construction of this Plan and the instruments evidencing
the Grants awarded hereunder shall be governed by the laws of the State of
Delaware (without giving effect to the choice of law provisions thereof).

     Securities Purchase Agreements, the Senior Notes or the Subordinated Notes
     without the written consent of those holders of the Senior Notes and the
     Subordinated Notes the consent of which would be necessary to waive such
     breach, default or event of default (and such consent shall not have been
     obtained), or

          (b)  payment of the Put Option Purchase Price is, at such time,
     prohibited by applicable law (including, without limitation, Section 18-607

deemed to be rescinded, subject to the right of the holders of such Bundled

the holders of the Senior Notes to receive payments in respect thereof, with the
same effect as if the provisions of Section 22 of the Securities Purchase

in this Section 2 to the contrary, the Company shall not at any time be
permitted to exercise the call option provided for in this Section 2, or pay the
Repurchase Price on the Call Repurchase Date, if, at such time:

          (a)  payment of the Repurchase Price at such time would result in a
     breach of, or default or event of default in respect of, the Securities
     Purchase Agreements, the Senior Notes or the Subordinated Notes without the
     written consent of those holders of the Senior Notes and the Subordinated
     Notes the consent of which would be necessary to waive such breach, default
     or event of default, or

          (b)  payment of the Repurchase Price is, at such time, prohibited by
     applicable law (including, without limitation, Section 18-607 of the
     Delaware Limited Liability Company Act).

3.   TAG-ALONG RIGHTS.

     3.1  TAG-ALONG RIGHTS IN RESPECT OF SALES BY INITIAL MEMBERS AND THE
          COMPANY.

          (a)  RIGHT TO SELL PROPORTIONATE NUMBER OF ISSUABLE UNITS. Each of the
     Initial Members hereby agrees that it will not sell all or any portion of
     the Issuable Units owned by it and the Company agrees that it will not sell
     any Issuable Units (other than in a registered public offering in which the
     holders of Bundled Securities are entitled to participate pursuant to
     Section 6.2) hereof unless, as part of such transaction, each holder of
     Bundled Securities shall have the right (but, subject to Section 4 hereof,
     not the obligation) to sell a proportionate amount of the Bundled
     Securities then held by such holder at the same price and on the same
     terms, and to the same purchaser or purchasers.

          For purposes of this Section 3.1, the "proportionate amount" which a
     holder of Bundled Securities shall be entitled to sell with respect to any
     proposed transaction shall be equal to the product (calculated as of the
     date of such proposed transaction) of:

               (i)  the total number of Bundled Securities then owned by such
          holder; times

               (ii) the quotient of:

                    (A)  the aggregate number of Issuable Units proposed to be
               sold in such transaction by the Other Members and/or the Company;
               divided by

                    (B)  the aggregate number of Issuable Units owned by the
               Other Members participating in such sale plus the aggregate
               number of Issuable Units, if any, proposed to be sold by the
               Company in such transaction.

          (b)  NOTICE OF PROPOSED SALE. The Initial Members and/or the Company
     intending to sell any Issuable Units shall provide to each of the holders
     of the Bundled Securities written notice of such intention not less than
     forty-five (45) days prior to the closing of such proposed sale. Such
     written notice (the "Notice of Sale") shall specify in detail the terms of
     such proposed sale (including the type of Security proposed to be sold and
     the price per unit of such Security), shall state the date on which such
     proposed sale is to be consummated and shall designate one party to whom
     notice of the determination to participate in such proposed sale should be

          (c)  ELECTION BY HOLDERS. Upon receipt of a Notice of Sale, each
     holder of Bundled Securities shall have twenty (20) days to deliver written
     notice of its election to participate in such sale and the number of
     Issuable Units which it elects to sell, which number shall not exceed its
     proportionate amount.

          (d)  PRO RATA CUTBACK OF NUMBER OF ISSUABLE UNITS SOLD. In the event
     that the Initial Members and/or the Company intending to sell the Issuable
     Units shall be unable to sell the aggregate number of Issuable Units to be
     sold by the Other Members and/or the Company and which the holders of the
     Bundled Securities have elected to sell pursuant to Section 3.1(a) hereof
     at the price specified in the Notice of Sale, then the number of Issuable
     Units to be sold by the Other Members and/or the Company and such holders
     of Bundled Securities electing to sell such Issuable Units shall be reduced
     ratably (as between such groups and as among the members of such groups) to
     the extent necessary to reduce the total number of Issuable Units to be
     included in such offering to the maximum number which the selling Other
     Members and/or the Company can sell at such price. Whether or not any such
     adjustment in the number of Issuable Units to be sold is required to be
     made, the Initial Members and/or the Company shall give each such holder
     which has elected to sell Issuable Units written notice of the number of
     Units it is permitted to sell pursuant to this Section 3.1 (after giving
     effect to the provisions of this Section 3.1(d)) not less than fifteen (15)
     days prior to the date of such sale.

          (e)  CONVERSION. As provided in the Limited Liability Company
     Agreement, the Issuable Units may be converted by the purchasers thereof
     into Class A Units.

          (f)  CLOSING OF SALE. Each holder of Bundled Securities electing to
     participate in a sale described in any Notice of Sale shall deliver to the
     purchaser specified in such Notice of Sale, against payment of the total
     purchase price for the Issuable Units to be purchased (at the price per
     Issuable Unit specified in such Notice of Sale), on the closing date
     specified in such Notice of Sale, a certificate or certificates, if any,
     representing the number of Issuable Units which it has elected to sell (net
     of any reduction pursuant to Section 3.1(d)) pursuant to this Section 3.1,
     together with appropriate instruments of transfer, if any, duly endorsed in
     blank.

          (g)  EXPENSES OF SALE. All expenses and costs of any sale of Issuable
     Units pursuant to this Section 3.1 (other than the fees of counsel to the
     holders of Bundled Securities related to such sale) shall be for the
     account of and paid by the Initial Members.

certificates evidencing such Rights. If the Issuable Units being issued consist
of Common Units, such holder shall receive a certificate or certificates, if
any, evidencing Common Units of such type.

     5.5  NO OTHER AUTHORIZATION OF EQUITY SECURITIES. The Company will not
authorize or issue any class of equity securities (including, without
limitation, Common Units) not authorized on the date hereof.

6.   REGISTRATION RIGHTS.

     6.1  REQUIRED REGISTRATION.

          (a)  FILING OF REGISTRATION STATEMENT. The Company will, upon the
     written request of the Initiating Holders given at any time after the
     Initial Public Offering Date requesting that the Company effect the
     registration under the Securities Act of all or part of such Initiating
     Holders' Registrable Securities and specifying the Registrable Securities
     to be sold and the intended method of disposition thereof, promptly give
     written notice of such requested registration to all holders of Registrable
     Securities, and thereupon will use its best efforts to effect the
     registration (the "Required Registration") under the Securities Act of:

               (i)  the Registrable Securities that the Company has been so
          requested to register by the Initiating Holders; and

               (ii) all other Registrable Securities that the Company has been
          requested to register by the holders thereof by written request given
          to the Company within thirty (30) days after the giving of such
          written notice by the Company (which request shall specify the
          Registrable Securities to be sold and the intended method of
          disposition of such Registrable Securities);

                                       10
<PAGE>
 
     all to the extent required to permit the disposition (in accordance with
     the intended method thereof as aforesaid) of the Registrable Securities so
     to be registered; provided, however, that the Company shall be required to
     effect only two (2) registrations pursuant to this Section 6.1 that are
     deemed effected under Section 6.1(e) hereof.

          (c)  TIME FOR FILING AND EFFECTIVENESS. On or before the date which is
     ninety (90) days after the request for such registration, the Company shall
     file with the SEC the Required Registration with respect to all Registrable
     Securities to be so registered, and shall use its best efforts to cause
     such Required Registration to become effective as promptly as practicable
     after the filing thereof, and use its best efforts to cause such Required
     Registration to become effective no later than the day which is one hundred
     eighty (180) days after the request for such registration.

          (c)  SELECTION OF UNDERWRITERS. If Registrable Securities that the
     Company has been requested to register pursuant to a Required Registration
     are to be disposed of in an underwritten public offering, the underwriters
     of such offering shall be one or more underwriting firms of recognized
     standing selected by the Requisite Holders and reasonably acceptable to the
     Company.

          (d)  PRIORITY ON REQUIRED REGISTRATIONS. If the managing underwriter
     shall advise the Company in writing (with a copy to each holder of
     Registrable Securities requesting sale) that, in such underwriter's
     opinion, the number of shares of Securities requested to be included in
     such Required Registration exceeds the number that can be sold in such
     offering within a price range acceptable to the Company (such writing to
     state the basis of such opinion and the approximate number of shares of
     Securities that may be included in such offering without such effect), the
     Company will include in such Required Registration, to the extent of the
     number of shares of Securities that the Company is so advised can be sold
     in such offering:

               (i)  first, Registrable Securities requested to be sold by the
          holders of Bundled Securities pursuant to this Section 6.1, pro rata
          among the holders requesting sale on the basis of the number of
          Issuable Units requested to be so registered by such holders; and

               (ii) second, all other Securities proposed to be registered by
          the Company and any Other Members, in such proportions as the Company
          and such Other Members shall agree.

          (e)  WHEN REQUIRED REGISTRATION IS DEEMED EFFECTED. A Required
     Registration pursuant to this Section 6.1 shall not be deemed to have been
     effected for purposes of the proviso to Section 6.1(a) hereof if:

                                       11
<PAGE>
 
          (i)   the registration does not become effective and remain effective
     for a period of at least one hundred eighty (180) days, without
     interference by the issuance by the SEC of any stop order with respect
     thereto;

          (ii)  in the case of any underwritten offering undertaken on a firm
     commitment basis, all the Registrable Securities requested to be registered
     in connection therewith were not sold;

          (iii) the Requisite Holders withdraw their request for registration in
     its entirety at any time because the Requisite Holders reasonably believed
     that the registration statement or any prospectus related thereto contained
     an untrue statement of a material fact or omitted to state a material fact
     required to be stated therein or necessary to make the statements made
     therein (in the case of any prospectus, in light of the circumstances under
     which they were made) not misleading, notified the Company of such fact and
     requested that the Company correct such alleged misstatement or omission,
     and the Company has refused to correct such alleged misstatement or
     omission; or

          (iv)  the conditions to closing specified in the purchase agreement or
     underwriting agreement entered into in connection with such Required
     Registration are not satisfied, other than by reason of some-act or
     omission by the holders of the Registrable Securities that were to have
     been registered and sold.

6.2  INCIDENTAL REGISTRATION.

     (A)  FILING OF REGISTRATION STATEMENT. If the Company at any time proposes
to register any of its Common Units (an "Incidental Registration") under the
Securities Act (other than pursuant to a registration statement on Form S-4 or
Form S-8 or any successor forms thereto, in connection with an offer made
solely to existing Security holders or employees of the Company), for sale to
the public in a public offering, it will each such time give prompt written
notice to all holders of Registrable Securities of its intention to do so, which
notice shall be given to all such holders at least thirty (30) Business Days
prior to the date that a registration statement relating to such registration is
proposed to be filed with the SEC. Upon the written request of any such holder
to include its shares under such registration statement (which request shall be
made within fifteen (15) Business Days after the receipt of any such notice and
shall specify the Registrable Securities intended to be disposed of by such
holder), the Company will use its best efforts to effect the registration of all
Registrable Securities that the Company has been so requested to register by
such holder; provided, however, that if, at any time after giving written notice
of its intention to register any Securities and prior to the effective date of
the registration statement filed in

                                       12
<PAGE>
 
     connection with such registration, the Company shall determine for any
     reason not to register such Common Units, the Company may, at its election,
     give written notice of such determination to each such holder and,
     thereupon, shall be relieved of its obligation to register any Registrable
     Securities of such Persons in connection with such registration.

          (b)  SELECTION OF UNDERWRITERS. Notice of the Company's intention to
     register such Common Units shall designate the proposed underwriters of
     such offering (which shall be one or more underwriting firms of recognized
     standing) and shall contain the Company's agreement to use its best
     efforts, if requested to do so, to arrange for such underwriters to include
     in such underwriting the Registrable Securities that the Company has been
     so requested to sell pursuant to this Section 6.2, it being understood that
     the holders of Registrable Securities shall have no right to select
     different underwriters for the disposition of their Registrable Securities.

          (c)  PRIORITY ON INCIDENTAL REGISTRATIONS. If the managing underwriter
     shall advise the Company in writing (with a copy to each holder of
     Registrable Securities requesting sale) that, in such underwriter's
     opinion, the number of shares of Common Units requested to be included in
     such Incidental Registration exceeds the number that can be sold in such
     offering within a price range acceptable to the Company (such writing to
     state the basis of such opinion and the approximate number of Common Units
     that may be included in such offering without such effect), the Company
     will include in such Incidental Registration, to the extent of the number
     of Common Units that the Company is so advised can be sold in such
     offering:

               (i)  in the case of any registration initiated by the Company for
          the purpose of selling Securities for its own account:

                    (A)  first, the number of Common Units that the Company
               proposes to issue and sell for its own account; and

                    (B)  second, Registrable Securities requested to be sold by
               the holders of Bundled Securities pursuant to this Section 6.2
               and all Common Units proposed to be registered by Other Members,
               pro rata among such holders on the basis of the number of
               Issuable Units requested to be so registered by such holders; and

               (ii) in the case of a registration initiated by any Other Member
          pursuant to demand or required registration rights in favor of such
          Other Member:

                    (A)  first, Registrable Securities requested to be sold by
               the Other Members requesting such Registration and Registrable

                                       13
<PAGE>
 
               Securities requested to be sold by the holders of Bundled
               Securities pursuant to this Section 6.2, pro rata among such
               holders on the basis of the number of Issuable Units requested to
               be so registered by such holders; and

                    (B) second, the number of Common Units that the Company
               proposes to issue and sell for its own account.

     6.3  REGISTRATION PROCEDURES. The Company will use its best efforts to
effect each Required Registration pursuant to Section 6.1 hereof and any
Incidental Registration of any Registrable Securities as provided in Section 6.2
hereof, and to cooperate with the sale of such Registrable Securities in
accordance with the intended method of disposition thereof as quickly as
practicable, and the Company will as expeditiously as possible:

          (a) subject, in the case of an Incidental Registration, to the proviso
     to Section 6.2(a), prepare and file with the SEC the registration statement
     and use its best efforts to cause the Registration to become effective;
     provided, however, that before filing any registration statement or
     prospectus or any amendments or supplements thereto, the Company will
     furnish to the holders of the Registrable Securities covered by such
     registration statement, their counsel, and the underwriters, if any, and
     their counsel, copies of each original registration statement proposed to
     be filed at least fifteen (15) days prior thereto and copies of each
     amendment, prospectus and supplement at least three (3) Business Days prior
     thereto, which documents will be subject to the reasonable review, within
     such period, of such holders, their counsel and the underwriters; and the
     Company will not file any registration statement or amendment thereto or
     any prospectus or any supplement thereto (including such documents
     incorporated by reference) to which the Requisite Holders shall reasonably
     object within such period;

          (b) subject, in the case of an Incidental Registration, to the proviso
     to Section 6.2(a), prepare and file with the SEC such amendments and post-
     effective amendments to any registration statement and any prospectus used
     in connection therewith as may be necessary to keep such registration
     statement effective and to comply with the provisions of the Securities Act
     with respect to the disposition of all Registrable Securities covered by
     such registration statement until such time as all of such Securities have
     been disposed of in accordance with the intended methods of disposition by
     the seller or sellers thereof set forth in such registration statement and
     cause the prospectus to be supplemented by any required prospectus
     supplement, and as so supplemented to be filed pursuant to Rule 424 under
     the Securities Act, provided that if the Company is not then eligible to
     use a registration statement on Form S-3 under the Securities Act, the
     Company shall not be obligated to keep such registration statement
     effective for more than two (2) years after the original effective date of
     such registration statement;

                                       14
<PAGE>
 
     (c)  furnish to each holder of Registrable Securities included in such
Registration and the underwriter or underwriters, if any, without charge, at
least one signed copy of the registration statement and any post-effective
amendment thereto, upon request, and such number of conformed copies thereof and
such number of copies of the prospectus (including each preliminary prospectus
and each prospectus filed under Rule 424 under the Securities Act), any
amendments or supplements thereto and any documents incorporated by reference
therein, as such holder or underwriter may reasonably request in order to
facilitate the disposition of the Registrable Securities being sold by such
holder (it being understood that the Company consents to the use of the
prospectus and any amendment or supplement thereto by each holder of Registrable
Securities covered by such registration statement and the underwriter or
underwriters, if any, in connection with the offering and sale of the
Registrable Securities covered by the prospectus or any amendment or supplement
thereto);

     (d)  notify each holder of the Registrable Securities of any stop order or
other order suspending the effectiveness of any registration statement, issued
or threatened by the SEC in connection therewith, and take all reasonable
actions required to prevent the entry of such stop order or to remove it or
obtain withdrawal of it at the earliest possible moment if entered;

     (e)  if requested by the managing underwriter or underwriters or any holder
of Registrable Securities in connection with any sale pursuant to a registration
statement, promptly incorporate in a prospectus supplement or post-effective
amendment such information relating to such underwriting as the managing
underwriter or underwriters or such bolder reasonably requests to be included
therein; and make all required filings of such prospectus supplement or post
effective amendment as soon as practicable after being notified of the matters
incorporated in such prospectus supplement or post-effective amendment;

     (f)  on or prior to the date on which a Registration is declared effective,
use its best efforts to register or qualify, and cooperate with the holders of
Registrable Securities included in such Registration, the underwriter or
underwriters, if any, and their counsel, in connection with the registration or
qualification of the Registrable Securities covered by such Registration for
offer and sale under the securities or "blue sky" laws of each state and other
jurisdiction of the United States as any such holder or underwriter reasonably
requests in writing; use its best efforts to keep each such registration or
qualification effective, including through new filings, or amendments or
renewals, during the period such registration statement is required to be kept
effective; and do any and all other acts or things necessary or advisable to
enable the disposition in all such jurisdictions reasonably requested of the
Registrable Securities covered by such Registration; provided, however, that the
Company will not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified or to

                                       15
<PAGE>
 
take any action which would subject it to general service of process in any such
jurisdiction where it is not then so subject;

     (g)  in connection with any sale pursuant to a Registration, cooperate with
the holders of Registrable Securities and the managing underwriter or
underwriters, if any, to facilitate the timely preparation and delivery of
certificates (not bearing any restrictive legends) representing Securities to be
sold under such Registration, and enable such Securities to be in such
denominations and registered in such names as the managing underwriter or
underwriters, if any, or such holders may request;

     (h)  use its best efforts to cause the Registrable Securities to be
registered with or approved by such other governmental agencies or authorities
within the United States and having jurisdiction over the Company or any
Subsidiary as may reasonably be necessary to enable the seller or sellers
thereof or the underwriter or underwriters, if any, to consummate the
disposition of such Securities;

     (i)  make available for inspection by any holder of Registrable Securities
included in any Registration, any underwriter participating in any disposition
pursuant to any Registration, and any attorney, accountant or other agent
retained by any such seller or underwriter, all financial and other records,
pertinent corporate documents and properties of the Company, as shall be
reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information reasonably requested by any such Person in connection
with such Registration;

     (j)  use its best efforts to obtain:

          (i)   at the time of effectiveness of each Registration, a "comfort
     letter" from the Company's independent certified public accountants
     covering such matters of the type customarily covered by "cold comfort
     letters" as the Requisite Holders and the underwriters reasonably request;
     and

          (ii)  at the time of any underwritten sale pursuant to the
     registration statement, a "bring-down comfort letter," dated as of the date
     of such sale, from the Company's independent certified public accountants
     covering such matters of the type customarily covered by comfort letters as
     the Requisite Holders and the underwriters reasonably request;

     (k)  use its best efforts to obtain, at the time of effectiveness of each
Incidental Registration and at the time of any sale pursuant to each
Registration, an opinion or opinions, favorable to the Requisite Holders in form
and scope, from counsel for the Company in customary form;

                                       16
<PAGE>
 
          (i)  notify each seller of Registrable Securities covered by such
     Registration, upon discovery that, or upon the happening of any event as a
     result of which, the prospectus included in such Registration, as then in
     effect, includes an untrue statement of a material fact or omits to state
     any material fact required to be stated therein or necessary to make the
     statements therein not misleading, and promptly prepare, file with the SEC
     and furnish to such seller or holder a reasonable number of copies of a
     supplement to or an amendment of such prospectus as may be necessary so
     that, as thereafter delivered to the purchasers or prospective purchasers
     of such Securities, such prospectus shall not include an untrue statement
     of a material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading in the
     light of the circumstances under which they are made;

          (m)  otherwise comply with all applicable rules and regulations of the
     SEC, and make generally available to its security holders (as contemplated
     by Section 11(a) under the Securities Act) an earnings statement satisfying
     the provisions of Rule 158 under the Securities Act not later than ninety
     (90) days after the end of the twelve (12) month period beginning with the
     first month of the Company's first fiscal quarter commencing after the
     effective date of the registration statement, which statement shall cover
     said twelve (12) month period;

          (n)  provide and cause to be maintained a transfer agent and registrar
     for all Registrable Securities covered by each Registration from and after
     a date not later than the effective date of such Registration;

          (o)  use its best efforts to cause all Registrable Securities covered
     by each Registration to be listed subject to notice of issuance, prior to
     the date of first sale of such Registrable Securities pursuant to such
     Registration, on each securities exchange on which the Common Units issued
     by the Company are then listed, and admitted to trading on NASDAQ, if the
     Common Units or any such other Securities are then admitted to trading on
     NASDAQ; and

          (p)  enter into such agreements (including underwriting agreements in
     customary form) and take such other actions as the Requisite Holders shall
     reasonably request in order to expedite or facilitate the disposition of
     such Registrable Securities.

The Company may require each holder of Registrable Securities that will be
included in such Registration to furnish the Company with such information in
respect of such holder of its Registrable Securities that will be included in
such Registration as the Company may reasonably request in writing and as is
required by applicable laws or regulations.

     6.4  PREPARATION; REASONABLE INVESTIGATION. In connection with the
preparation and filing of each registration statement registering Registrable
Securities under the

                                       17
<PAGE>
 
Securities Act, the Company will give the holders of such Registrable Securities
so registered, their underwriters, if any, and their respective counsel and
accountants the opportunity to participate in the preparation of such
registration statement (other than reports and proxy statements incorporated
therein by reference and lawfully and properly filed with the SEC) and each
prospectus included therein or filed with the SEC, and each amendment thereof or
supplement thereto, and will give each of them such access to its books and
records and such opportunities to discuss the business of the Company with its
officers and the independent public accountants who have certified its financial
statements as shall be necessary, in the opinion of such holders' or such
underwriters' to conduct a reasonable investigation within the meaning of the
Section 11 (b)(3) of the Securities Act.

     6.5  RIGHTS OF REQUESTING HOLDERS. Each holder of Registrable Securities
which makes a written request therefor within thirty (30) days after the notice
to such holders provided for in Section 6.1 or Section 6.2 hereof, as the case
may be, hereof, shall have the right to receive the copies of the information,
notices and other documents described in Section 6.3(c), Section 6.3(l) and
Section 6.3(m) hereof in connection with any proposed Registration by the
Company under the Securities Act.

     6.6  REGISTRATION EXPENSES. The Company will pay all Registration Expenses
in connection with each registration of Registrable Securities, including,
without Limitation, any such registration not effected by the Company.

     6.7  INDEMNIFICATION; CONTRIBUTION.

          (a)  INDEMNIFICATION BY THE COMPANY. The Company shall indemnify, to
     the fullest extent permitted by law, each holder of Registrable Securities,
     its officers, directors and agents, if any, and each Person, if any, who
     controls such holder within the meaning of section 15 of the Securities
     Act, against all losses, claims, damages, liabilities (or proceedings in
     respect thereof) and expenses (under the Securities Act or common law or
     otherwise), joint or several, resulting from any violation by the Company
     of the provisions of the Securities Act or any untrue statement or alleged
     untrue statement of a material fact contained in any registration statement
     or prospectus (and as amended or supplemented if amended or supplemented)
     or any preliminary prospectus or caused by any omission or alleged omission
     to state therein a material fact required to be stated therein or necessary
     to make the statements therein (in the case of any prospectus, in light of
     the circumstances under which they were made) not misleading, except to the
     extent that such losses, claims, damages, liabilities (or proceedings in
     respect thereof) or expenses are caused by any untrue statement or alleged
     untrue statement contained in or by any omission or alleged omission from
     information concerning any holder furnished in writing to the Company by
     such holder expressly for use therein. If the offering pursuant to any
     registration statement provided for under this Section 6 is made through
     underwriters, no action or failure to act on the part of such underwriters
     (whether or not such

                                       18
<PAGE>
 
     underwriter is an Affiliate of any holder of Registrable Securities) shall
     affect the obligations of the Company to indemnify any holder of
     Registrable Securities or any other Person pursuant to the preceding
     sentence. If the offering pursuant to any registration statement provided
     for under this Section 6 is made through underwriters, the Company agrees,
     to the extent required by such underwriters, to enter into an underwriting
     agreement in customary form with such underwriters and to indemnify such
     underwriters, their officers, directors and agents, if any, and each
     Person, if any, who controls such underwriters within the meaning of
     section 15 of the Securities Act to the same extent as hereinbefore
     provided with respect to the indemnification of the holders of Registrable
     Securities; provided that the Company shall not be required to indemnify
     any such underwriter, or any officer or director of such underwriter or any
     Person who controls such underwriter within the meaning of section 15 of
     the Securities Act, to the extent that the loss, claim, damage, liability
     (or proceedings in respect thereof) or expense for which indemnification is
     claimed results from such underwriter's failure to send or give a copy of
     an amended or supplemented final prospectus to the Person asserting an
     untrue statement or alleged untrue statement or omission or alleged
     omission at or prior to the written confirmation of the sale of Registrable
     Securities to such Person if such statement or omission was corrected in
     such amended or supplemented final prospectus prior to such written
     confirmation and the underwriter was provided with such amended or
     supplemented final prospectus.

          (b)  INDEMNIFICATION BY THE HOLDERS. In connection with any
     registration statement in which a holder of Registrable Securities is
     participating, each such holder, severally and not jointly, shall
     indemnify, to the fullest extent permitted by law, the Company, each
     underwriter and their respective officers, directors and agents, if any,
     and each Person, if any, who controls the Company or such underwriter
     within the meaning of section 15 of the Securities Act, against any losses,
     claims, damages, liabilities (or proceedings in respect thereof) and
     expenses resulting from any untrue statement or alleged untrue statement of
     a material fact or any omission or alleged omission of a material fact
     required to be stated in the registration statement or prospectus or
     preliminary prospectus or any amendment thereof or supplement thereto or
     necessary to make the statements therein (in the case of any prospectus, in
     light of the circumstances under which they were made) not misleading, but
     only to the extent that such untrue statement is contained in or such
     omission is from information so concerning a holder furnished in writing by
     such holder expressly for use therein; provided, however, that such
     holder's obligations hereunder shall be limited to an amount equal to the
     proceeds to such holder of the Registrable Securities sold pursuant to such
     registration statement.

          (c)  CONTROL OF DEFENSE. Any Person entitled to indemnification under
     the provisions of this Section 6.7 shall give prompt notice to the
     indemnifying party of any claim with respect to which it seeks
     indemnification and unless in such indemnified party's reasonable judgment
     a conflict of interest between such

     indemnified and indemnifying parties may exist in respect of such claim,
     permit such indemnifying party to assume the defense of such claim, with
     counsel reasonably satisfactory to the indemnified party; and if such
     defense is so assumed, such indemnifying party shall not enter into any
     settlement without the consent of the indemnified party if such settlement
     attributes liability to the indemnified party and such indemnifying party
     shall not be subject to any liability for any settlement made without its
     consent (which shall not be unreasonably withheld); and any underwriting
     agreement entered into with respect to any registration statement provided
     for under this Section 6 shall so provide. In the event an indemnifying
     party shall not be entitled, or elects not, to assume the defense of a
     claim, such indemnifying party shall not be obligated to pay the fees and
     expenses of more than one counsel or firm of counsel for all parties
     indemnified by such indemnifying party in respect of such claim, unless in
     the reasonable judgment of any such indemnified party a conflict of
     interest may exist between such indemnified party and any other of such
     indemnified parties in respect to such claim.

          (d)  CONTRIBUTION. If for any reason the foregoing indemnity is
     unavailable, then the indemnifying party shall contribute to the amount
     paid or payable by the indemnified party as a result of such losses,
     claims, damages, liabilities or expenses:

               (i)  in such proportion as is appropriate to reflect the relative
          benefits received by the indemnifying party on the one hand and the
          indemnified party on the other; or

               (ii) if the allocation provided by clause (i) above is not
          permitted by applicable law or provides a lesser sum to the
          indemnified party than the amount hereinafter calculated, in such
          proportion as is appropriate to reflect not only the relative benefits
          received by the indemnifying party on the one hand and the indemnified
          party on the other but also the relative fault of the indemnifying
          party and the indemnified party as well as any other relevant
          equitable considerations.

Notwithstanding the foregoing, no holder of Registrable Securities shall be
required to contribute any amount in excess of the amount such holder would
have been required to pay to an indemnified party if the indemnity under Section
6.7(b) hereof was available. No Person guilty of fraudulent misrepresentation
(within the meaning of section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation. The obligation of any Person to contribute pursuant to this
Section 6.7 shall be several and not joint.

          (e)  TIMING OF PAYMENTS. An indemnifying party shall make payments of
     all amounts required to be made pursuant to the foregoing provisions of
     this Section 6.7 to or for the account of the indemnified party from time
     to time

                                       20
<PAGE>
 
     promptly upon receipt of bills or invoices relating thereto or when
     otherwise due or payable.

          (f)  SURVIVAL. The indemnity and contribution agreements contained in
     this Section 6.7 shall remain in full force and effect regardless of any
     investigation made by or on behalf of a participating holder of Registrable
     Securities, its officers, directors, agents or any Person, if any, who
     controls such holder as aforesaid, and shall survive the transfer of such
     Securities by such holder.

          (a)  In connection with each underwritten sale of Registrable
     Securities, the Company agrees, and each holder of Registrable Securities
     by acquisition of such Registrable Securities agrees, to enter into
     customary holdback agreements concerning sale or distribution of
     Registrable Securities and other equity Securities of the Company, except,
     in the case of any holder of Registrable Securities, to the extent that
     such holder is prohibited by applicable law or exercise of fiduciary duties
     from agreeing to withhold Registrable Securities from sale or is acting in
     its capacity as a fiduciary or investment adviser. Without limiting the
     scope of the term "fiduciary," a holder shall be deemed to be acting as a
     fiduciary or an investment adviser if its actions or the Registrable
     Securities proposed to be sold are subject to the Employee Retirement
     Income Security Act of 1974, as amended, or the Investment Company Act of
     1940, as amended, or if such Registrable Securities are held in a separate
     account under applicable insurance law or regulation.

     any holder of any Securities of the Company rights with respect to the
     registration of such Securities under the Securities Act:

               (i)   such rights shall not be in conflict with or adversely
          affect any of the rights provided in this Section 6 to the holders of
          Registrable Securities; and

               (ii)  if such rights are provided on terms or conditions more 
          favorable to such holder than the terms and conditions provided in
          this Section 6, the Company will provide (by way of amendment to this
          Section 6 or otherwise) such more favorable terms or conditions to the
          holders of Registrable Securities.

     6.9  OTHER REGISTRATION OF COMMON UNITS. If any Common Units required to be
reserved for purposes of conversion of any class of Common Units into any other
class of Common Units require registration with or approval of any governmental
authority under any federal or state law (other than the Securities Act) before
such Common Units may be issued upon conversion, the Company will, at its
expense and as

                                       21
<PAGE>
 
expeditiously as possible, use its best efforts to cause such Common Units to be
duly registered or approved, as the case may be.

     6.10 AVAILABILITY OF INFORMATION. The Company will comply with the
reporting requirements of Sections 13 and 15(d) of the Exchange Act and will
comply with all other public information reporting requirements of the SEC as
from time to time in effect, and cooperate with the holders of Registrable
Securities, so as to permit disposition of the Registrable Securities pursuant
to an exemption from the Securities Act for the sale of any Registrable
Securities (including, without limitation, the current public information
requirements of Rule 144(c) and Rule 144A under the Securities Act). The Company
win also cooperate with each holder of any Registrable Securities in supplying
such information as may be necessary for such holder to complete and file any
information reporting forms presently or hereafter required by the SEC as a

                           --------               
paid in full or will be repaid in full, together with all accrued interest and

Holders.

civil disturbances; expropriation or confiscation of facilities or compliance
with any order or request of governmental authority; strikes, labor or
employment difficulties whether direct or indirect; or any cause whatsoever

                     Products;

                     pay the Company all sums then outstanding and owed to the
                     Company; and

                (7)  all provisions of this Agreement except 14(a) shall remain
                     in full force and effect.

            (d) Company's Obligations. If this Agreement is terminated by the
                ---------------------
Company, the Company shall, within sixty days of such termination, purchase
Distributor's inventory of Trex Products at a price equal to the price initially
paid by the Distributor for such products.

            (e) Rights of the Company.
                ---------------------

                (I)   If the Distributor shall refuse or fail to comply with any
of the foregoing provisions of this Section 13, the Distributor shall be liable
to and shall indemnify and reimburse the Company for all costs, attorney fees,
and/or other expenses incurred by the Company in connection with the enforcement
of said provisions, provided, however, that the remedies provided herein shall
not be exclusive of other remedies available to the Company.

                (ii)  The Company may set-off or apply any sums due the
Distributor to any sums for which the Distributor is indebted or owes to the
Company.

        14. RESTRICTIVE COVENANTS
            ---------------------

            (a) Noncompetition. The Distributor acknowledges that confidential
                -------------- 
information relative to marketing, manufacturing and installing methods for Trex
Products will be made available to the Distributor during the term of this
Agreement. Furthermore, the Distributor will enjoy the benefits and goodwill of
the Trex trade name, the opportunity and right to sell the quality products
associated therewith, the goodwill generated for Trex Products by the Company
and its other distributors, as well as the marketing and technical support of
the Company, all of which the Distributor agrees and acknowledges is highly
advantageous and valuable to the Distributor. In order to protect the Company's
interest in the aforesaid and to strengthen the Distributor's commitment to the
promotion of Trex Products, the Distributor and each of the individuals signing
this Agreement on behalf of the Distributor agrees that during the term of this
Agreement, that neither the Distributor nor the designated individuals will, in
any manner, directly or indirectly, except with the prior written consent of the
Company, promote, advertise,


                                        7
<PAGE>
 
manufacture, market, distribute, sell or install a product produced from
composite recycled plastics and composite recycled wood fibers which competes
with Trex Products, which has the same purpose, function or use as Trex
Products, or which is essentially of the same or similar design as Trex
Products. This restriction applies to all Distributor locations that are
authorized to sell Trex. The Distributor will make its best effort to restrict
any confidential information including pricing, marketing programs, and product
development plans to the locations authorized to sell Trex.

            (b) Nonsolicitation. The Distributor, and each of the individuals
                ---------------
signing this Agreement on behalf of the Distributor, agrees that during the term
of this Agreement, except as expressly permitted by this Agreement, and for a
period of 24 months after termination of this Agreement for any reason, neither
the Distributor nor any of the signing individuals, will solicit, or cause to be
solicited, the employees of the Company.

            (c) Extension. The period of time during which the Distributor and
                ---------
the individuals signing on its behalf are prohibited from engaging in the
business activities specified in the provisions of Sections 14(a) and 14(b)
shall be extended by any length of time during which the Distributor or a
signing individual is in breach of such provisions.

            (d) Enforcement.
                -----------

                (i)   It is agreed and understood by and among the parties to
this Agreement that the restrictive covenants set forth in this Section 14 are
essential elements of this Agreement and that, but for the agreement of the
Distributor to comply with such covenants, the Company would not have agreed to
enter into this Agreement. Such covenants of the Distributor shall be construed
as agreements independent of any other provisions of this Agreement and shall
survive the termination of this Agreement and continue for the duration
specified. The existence of any claim or cause of action of the Distributor
against the Company, whether predicated on this Agreement or otherwise, shall
not constitute a defense to the enforcement by the Company of such restrictive
covenants.

                (ii)  It is agreed by the parties to this Agreement that if any
portion of the restrictive covenants set forth in Sections 14(a) and 14(b) is
held to be unreasonable, arbitrary or against public policy, then each such
covenant shall be considered divisible both as to time and geographical area,
with each month of a specified period being deemed a separate period of time and
each county within each state being deemed a separate geographical area, it
being the intention of the parties that a lesser period of time or geographical
area shall be enforced so long as the same is not unreasonable, arbitrary or
against public policy. The parties to this Agreement agree that, in the event
any court of competent jurisdiction determines that a specified time period or a
specified geographical area is unreasonable, arbitrary or against public policy,
a lesser time period or geographical area which is determined to be reasonable,
nonarbitrary and not against public policy may be enforced against the
Distributor.


                                        8
<PAGE>
 
             (iii) The parties hereto agree that damages at law will be an
insufficient remedy to the Company in the event that the restrictive covenants
of this Section 14 are violated and that in addition to any other remedies of
rights that may be available to the Company, the Company shall also be entitled,
upon application to a court of competent jurisdiction, to obtain injunctive
relief to enforce the provisions of this Section 14.

         (e) Binding on Individuals. Each of the individuals signing this
             ----------------------
Agreement on behalf of the Distributor specifically agrees to be fully bound by
the foregoing restrictive covenants of this Section 14.

     15. CONFIDENTIAL INFORMATION
         ------------------------

         (a) Except as authorized in writing by the Company, Distributor shall
not at any time, either during or after the term of this Agreement, disclose or
use, directly or indirectly, any proprietary information of the Company of which
the Distributor gains knowledge during or by reason of this Agreement and the
Distributor shall retain all such information in trust in a fiduciary capacity
for the sole use and benefit of the Company.

         (b) Proprietary information means information developed by or for the
Company which is not otherwise generally known in any industry in which the
Company is or may become engaged and includes, but is not limited to,
information developed by or for the Company, whether now owned or hereafter
obtained, concerning plans, marketing and sales methods, materials, processes,
procedures, devices utilized by the Company, prices, suppliers, manufacturers,
customers with whom the Company deals (or organizations or other entities or
persons associated with such customers), trade secrets and other confidential
information of any type, together with all written, graphic and other materials
relating to all or any part of the same.

         (c) The Distributor acknowledges that the proprietary information of
the Company is valuable, special and unique to the Company's business, that on
such proprietary information the Company's business depends and that the Company
wishes to protect such proprietary information by keeping it secret and
confidential for the sole use and benefit of the Company. The Distributor shall
take all steps necessary, and all steps reasonably requested by the Company, to
insure that all such information is kept secret and confidential for the sole
use and benefit of the Company, including, if requested by the Company, using
its best efforts to have all employees and agents of the Distributor execute and
deliver to the Company confidentiality agreements in a form satisfactory to the
Company. Distributor represents that it has a policy and procedure designed to
protect all proprietary information including notices to its employees to
prevent unauthorized publication and disclosure of any such information.

                                        9
<PAGE>
 
         (d) Upon termination of this Agreement, the Distributor shall promptly
return to the Company any property of the Company, including, without
limitation, all sales and marketing documents, manuals and other records and
proprietary information of the Company, as well as any samples in the
Distributor's possession or control, whether prepared by the Distributor or
others and whether the Distributor acquired or received such property or
material in connection with its performance under this Agreement or otherwise.
The Distributor agrees that it will not make or retain any copy of, or extract
from, such property or materials. The Company agrees to compensate the
Distributor for the cost of any returned sales materials that were authorized by
the Company and purchased by the Distributors within 12 months of the date of
termination.

     16. GENERAL
         -------

         (a) Insurance. Both parties hereto agrees to carry such liability
             ---------
insurance and/or other insurance as they deem advisable in connection with their
respective businesses. Neither party shall be obligated to carry any insurance
for the protection of the other.

         (b) Waiver. Failure of either party at any time to require performance
             ------
by the other party of any provision hereof shall not be deemed to be a
continuing waiver of that provision, or a waiver of its rights under any other
provision of this Agreement, regardless of whether such provision is of the same
or a similar nature.

         (c) Specific Performance. The parties agree that the subject matter of
             --------------------
this Agreement is unique and that damages at law will be insufficient to protect
the interests of the Company in the case of a violation by the Distributor of
its obligations under this Agreement. In addition to any remedies or rights that
may be available to the Company under this Agreement, the Company shall be
entitled, upon application to a court of competent jurisdiction, to obtain
injunctive relief to enforce the provisions of this Agreement against the
Distributor.

         (d) Effective Date. This Agreement shall not become effective until
             --------------
accepted and executed by the Company in Winchester, Virginia.

         (e) Complete Agreement. This Agreement (including the exhibits hereto
             ------------------
and all documents and papers delivered pursuant hereto and any written
amendments hereof executed by the parties to this Agreement) constitutes the
entire agreement, and supersedes all prior agreements and understandings, oral
and written, among the parties to this Agreement with respect to the subject
matter hereof. This Agreement may be amended only by written agreement executed
by all of the parties hereto. No purchase order or sales form will be applicable
to any sales pursuant to this Agreement and only the terms of this Distributor
Agreement shall govern such sales.

<PAGE>
 
         (f) Applicable Law: Severability.
             ----------------------------

             (i) This Agreement shall be construed under, and governed by, the
laws of the State of Virginia (except that if any choice of law provision of
Virginia law would result in the application of the law of a state or
jurisdiction other than Connecticut, such provision shall not apply). The
parties agree that jurisdiction and venue for any legal proceedings arising from
or in any way connected to this Agreement will lie in the State Court of any
appropriate county in the state of Virginia.

             (ii) If any provision of this Agreement is unenforceable or
invalid, the Agreement shall be ineffective only to the extent of such
provisions, and the enforceability or validity of the remaining provisions of
this Agreement shall not be affected thereby.

         (g) Transfer by the Distributor. Without the prior written approval of
             ---------------------------
the Company (which shall not be unreasonably withheld), the Distributor shall
have no right to sell, assign, transfer, convey, give away, pledge, mortgage or
encumber or otherwise dispose of the license granted hereunder or any interest
in this Agreement. Any transfer, assignment or other disposition made other than
in accordance with the requirements of this Agreement, whether made by operation
of law or otherwise or for no consideration, shall be null and void and without
any legal force or effect; and, the Company shall not be obligated to recognize
the same. Prior to making any proposed assignment, transfer or other disposition
of the Distributor or an interest in this Agreement, the Distributor shall
provide the Company with 60 days' prior written notice, which notice shall
include a complete and accurate written description of the purpose, terms and
conditions of the proposed transaction.

         (h) Assignment by the Company. Upon thirty days' prior written notice
             -------------------------
to the Distributor, the Company may assign its rights, duties and obligations
under this Agreement.

         (i) Notices. Any notice or other communication related to this
             -------
Agreement shall be effective if sent by first class mail, postage prepaid, to
the address set forth in this Agreement, or to such other address as may be
designated in writing to the other party.

         (j) Headings. The section and other headings in this Agreement are for
             --------
purposes of reference only and shall not be referred to in interpreting its
provisions.

                                PROMISSORY NOTE


$3,780,000.00                                                     June 15, 1998



TREX COMPANY, LLC
20 S. CAMERON STREET
WINCHESTER, VIRGINIA  22601
(Individually and collectively, "Borrower")

FIRST UNION NATIONAL BANK
201 S. JEFFERSON STREET
ROANOKE, VIRGINIA  24011
(Hereinafter referred to as the "Bank")

Borrower promises to pay to the order of Bank, in lawful money of the United
States of America, at its office indicated above or wherever else Bank may
specify, the sum of Three Million Seven Hundred Eighty Thousand Dollars and No
Cents ($3,780,000.00) or such sum as may be advanced and outstanding from time
to time, with interest on the unpaid principal balance at the rate and on the
terms provided in this Promissory Note (including all renewals, extensions or
modifications hereof, this "Note").

SECURITY.  Borrower has granted Bank a security interest in the collateral
described in the Loan Documents including, but not limited to, real property
collateral described in that certain Deed of Trust of even date herewith.

INTEREST RATE DEFINITIONS.

LIBOR.  1-Month LIBOR Rate plus (100 basis points) ("LIBOR-Based Rate"). "LIBOR"
is the rate for U.S. dollar deposits of that many months maturity as reported on
Telerate page 3750 as of 11:00 a.m., London time, on the second London business
day before the relevant Interest Period begins (or if not so reported, then as
determined by the Bank from another recognized source or interbank quotation).

INTEREST RATE TO BE APPLIED.

INTEREST RATE. Subject to the provisions hereof, the unpaid principal balance of
this Note shall bear interest from the date hereof at the LIBOR-Based Rate, as
determined by Bank prior to the commencement of each consecutive interest period
of 1 month (each, an "Interest Period") during the term of the Note. Upon
determination by Bank of the LIBOR-Based Rate for any Interest Period, such
LIBOR-Based Rate shall remain in effect, subject to the provisions hereof, for
the entire Interest Period until redetermined as provided above for the next
successive Interest Period.

INDEMNIFICATION.  Borrower indemnifies Bank against Bank's loss or expense in
employing deposits as a consequence of (a) Borrower's failure to make any
payment when due under this Note, or (b) any payment, prepayment or conversion
of any loan on a date other than the last day of the Interest Period
("Indemnified Loss or Expense"). The amount of such Indemnified Loss or Expense
shall be determined by Bank based upon the assumption that Bank funded 100% of
that portion of the loan in the London interbank market.

DEFAULT RATE.  In addition to all other rights contained in this Note, if a
Default (defined herein) occurs and as long as a Default continues, all
outstanding Obligations shall bear interest at the LIBOR-Based Rate plus 3%
("Default Rate"). The Default Rate shall also apply from acceleration until the
Obligations or any judgment thereon is paid in full.

INTEREST AND FEE(S) COMPUTATION (ACTUAL/360) . Interest and fees, if any, shall
be computed on the basis of a 360-day year for the actual number of days in the
applicable period ("Actual/360 Computation"). The Actual/360 
<PAGE>
 
Computation determines the annual effective yield by taking the stated (nominal)
rate for a year's period and then dividing said rate by 360 to determine the
daily periodic rate to be applied for each day in the applicable period.
Application of the Actual/360 Computation produces an annualized effective
interest rate exceeding that of the nominal rate.

REPAYMENT TERMS. This Note shall be due and payable as set forth in the
Repayment Schedule attached hereto and made a part hereof. All remaining
principal and interest shall be due and payable on June 16, 2008.

SCHEDULED PAYMENT ADJUSTMENT.  At Bank's option and with notice to Borrower, the
scheduled payment amount will increase as is necessary (i) to pay all accruals
of interest for the period and previous periods and (ii) to maintain principal
repayment according to the amortization that would have occurred if the Interest
Rate in effect on the date of this Note had remained constant. The increased
payment amount shall remain in effect for as long as the original scheduled
payment amount is insufficient to pay accrued interest and principal and shall
be further adjusted upward or downward to reflect changes in the variable
interest rate. The scheduled payment amount will not be reduced below the
original scheduled payment amount.

APPLICATION OF PAYMENTS. Monies received by Bank from any source for application
toward payment of the Obligations shall be applied to accrued interest and then
to principal. If a Default occurs, monies may be applied to the Obligations in
any manner or order deemed appropriate by Bank.

If any payment received by Bank under this Note or other Loan Documents is
rescinded, avoided or for any reason returned by Bank because of any adverse
claim or threatened action, the returned payment shall remain payable as an
obligation of all persons liable under this Note or other Loan Documents as
though such payment had not been made.

LOAN DOCUMENTS AND OBLIGATIONS. The term "Loan Documents" used in this Note and
other Loan Documents refers to all documents executed in connection with the
loan evidenced by this Note and any prior notes which evidence all or any
portion of the loan evidenced by this Note, and may include, without limitation,
a commitment letter that survives closing, a loan agreement, this Note, guaranty
agreements, security agreements, security instruments, financing statements,
mortgage instruments, letters of credit and any renewals or modifications,
whenever any of the foregoing are executed, but does not include swap agreements
(as defined in 11 U.S.C.(S)101).

The term "Obligations" used in this Note refers to any and all indebtedness and
other obligations under this Note, all other obligations under any other loan
Document(s), and all obligations under any swap agreements as defined in 11
U.S.C.(S)101 between Borrower and Bank whenever executed including the ISDA
Master Agreement dated March 20, 1998 between Bank and Borrower.

LATE CHARGE. If any payments are not timely made, Borrower shall also pay to
Bank a late charge equal to five percent (5%) of each payment past due for eight
(8) or more days.

Acceptance by Bank of any late payment without an accompanying late charge shall
not be deemed a waiver of Bank's right to collect such late charge or to collect
a late charge for any subsequent late payment received.

If this Note is secured by owner-occupied residential real property located
outside the state in which the office of Bank first shown above is located, the
late charge laws of the state where the real property is located shall apply to
this Note and the late charge shall be the highest amount allowable under such
laws. If no amount is stated thereunder, the late charge shall be five percent
(5%) of each payment past due for ten (10) or more days.

ATTORNEYS' FEES AND OTHER COLLECTION COSTS. Borrower shall pay all of Bank's
reasonable expenses incurred to enforce or collect any of the Obligations,
including, without limitation, reasonable arbitration, paralegals', attorneys'
and experts' fees and expenses, whether incurred without the commencement of a
suit, in any trial, arbitration, or administrative proceeding, or in any
appellate or bankruptcy proceeding.

USURY. Regardless of any other provision of this Note or other Loan Documents,
if for any reason the effective interest should exceed the maximum lawful
interest, the effective interest shall be deemed reduced to, and shall be, such
maximum lawful interest, and (i) the amount which would be excessive interest
shall be deemed applied to the reduction of the principal balance of this Note
and not to the payment of interest, and (ii) if the loan evidenced by this Note
has been or is thereby paid in full, the excess shall be returned to the party
paying same, such application to the principal balance of this Note or the
refunding of excess to be a complete settlement and acquittance thereof.
<PAGE>
 
DEFAULT. If any of the following occurs a default ("Default") under this Note
shall exist: NONPAYMENT; NONPERFORMANCE. The failure of timely payment or
performance of the Obligations or Default under this Note or any other Loan
Documents. FALSE WARRANTY. A warranty or representation made deemed made in the
Loan Documents or furnished Bank in connection with the loan evidenced by this
Note proves materially false, or if of a continuing nature, becomes materially
false. CROSS DEFAULT. At Bank's option, any default in payment or performance of
any obligation under any other loans, contracts or agreements of Borrower, any
Subsidiary or Affiliate of Borrower, any general partner of or the holder(s) of
the majority ownership interests of Borrower with Bank or its affiliates

the term "debtor" therein shall be substituted by the term "Borrower" herein;
"Subsidiary" shall mean any corporation of which more than 50% of the issued or
outstanding voting stock is owned directly or indirectly by Borrower).
CESSATION; BANKRUPTCY. The death of, appointment of guardian for, dissolution
of, termination of existence of, loss of good standing status by, appointment of
a receiver for, assignment for the benefit of creditors of, or commencement of
any bankruptcy or insolvency proceeding by or against Borrower, its Subsidiaries
or Affiliates, if any, or any general partner of or the holder(s) of the
majority ownership interests of Borrower, or any party to the Loan Documents.
MATERIAL CAPITAL STRUCTURE OR BUSINESS ALTERATION. Without prior written consent
of Bank, (i) a material alteration in the kind or type of Borrower's business or
that of Borrower's Subsidiaries or Affiliates, if any; (ii) the sale of more
than 50% of the Borrower's outstanding stock or voting power of or in a single
transaction or a series of transactions; (iii) the acquisition of substantially
all of the business or assets or more than 50% of the outstanding stock or
voting power of any other entity; or (iv) should any Borrower, or any of
Borrower's Subsidiaries or Affiliates, or any guarantor enter into any merger or
consolidation.

REMEDIES UPON DEFAULT. If a Default occurs under this Note or any Loan
Documents, Bank may at any time thereafter, take the following actions: BANK
LIEN. Foreclose its security interest or lien against Borrower's accounts
without notice. ACCELERATION UPON DEFAULT. Accelerate the maturity of this Note
and all other of the Obligations shall be immediately due and payable.
CUMULATIVE. Exercise any rights and remedies as provided under the Note and
other Loan Documents, or as provided by law or equity.

FINANCIAL AND OTHER INFORMATION. Borrower shall deliver to Bank such information
as Bank may reasonably request from time to time, including without limitation,
financial statements and information pertaining to Borrower's financial
condition. Such information shall be true, complete, and accurate.

YEAR 2000 COMPATIBILITY. Borrower shall take all action necessary to assure that
Borrower's computer based systems are able to operate and effectively process
data including dates on and after January 1, 2000. At the request of Bank,
Borrower shall provide Bank assurance acceptable to Bank of Borrower's Year 2000
compatibility.

LOAN AGREEMENT. Borrower represents and warrants that the provisions of Article
IV (excluding Sections 4.04 and 4.05) of the Credit Agreement between Bank and
Borrower dated December 10, 1996, and all modifications and amendments thereof
(the "Credit Agreement") are true and correct as of the date of the Note; and at
all times, Borrower shall comply with the provisions of Article V of the Credit
Agreement. Borrower's obligation to comply with such provisions shall continue
notwithstanding the satisfaction in full of all obligations referred to in the
Credit Agreement.

WAIVERS AND AMENDMENTS. No waivers, amendments or modifications of this Note and
other Loan Documents shall be valid unless in writing and signed by an officer
of Bank. No waiver by Bank of any Default shall operate as a waiver of any other
Default or the same Default on a future occasion. Neither the failure nor any
delay on the part of Bank in exercising any right, power, or remedy under this
Note and other Loan Documents shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or remedy.

Each Borrower or any other person liable under this Note waives presentment,
protest, notice of dishonor, demand for payment, notice of intention to
accelerate maturity, notice of acceleration of maturity, notice of sale and all
other notices of any kind. Further, each agrees that Bank may extend, modify or
renew this Note or make a novation of the loan evidenced by this Note for any
period and grant any releases, compromises or indulgences with respect to any
collateral securing this Note, or with respect to any other Borrower or any
person liable under this Note or other Loan Documents, all without notice to or
consent of each Borrower or each person who may be liable under this Note or
other Loan Documents and without affecting the liability of Borrower or any
person who may be liable under this Note or other Loan Documents.

MISCELLANEOUS PROVISIONS. ASSIGNMENT. This Note and other Loan Documents shall
inure to the benefit of and be binding upon the parties and their respective
heirs, legal representatives, successors and assigns. Bank's interests in and
rights under this Note and other Loan Documents are freely assignable, in whole
or in part, by Bank. In addition, nothing in 
<PAGE>
 
this Note or any of the Loan Documents shall prohibit Bank from pledging or
assigning this Note or any of the Loan Documents or any interest therein to any
Federal Reserve Bank. Borrower shall not assign its rights and interest
hereunder without the prior written consent of Bank, and any attempt by Borrower
to assign without Bank's prior written consent is null and void. Any assignment
shall not release Borrower from the Obligations. APPLICABLE LAW; CONFLICT
BETWEEN DOCUMENTS. This Note and other Loan Documents shall be governed by and
construed under the laws of the state named in Bank's address shown above
without regard to that state's conflict of laws principles. If the terms of this
Note should conflict with the terms of the Loan Agreement or any commitment

JURISDICTION. Borrower irrevocably agrees to non-exclusive personal jurisdiction
in the state named in Bank's address shown above. SEVERABILITY. If any provision
of this Note or of the other Loan Documents shall be prohibited or invalid under
applicable law, such provision shall be ineffective but only to the extent of
such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Note or other such document.
NOTICES. Any notices to Borrower shall be sufficiently given, if in writing and

exemplary damages against the other in any Dispute and hereby waive any right or
claim to punitive or exemplary damages they have now or which may arise in the

                                 PROMISSORY NOTE


$1,035,000.00                                                  November 20, 1998


TREX COMPANY, LLC
20 S. CAMERON STREET
WINCHESTER, VIRGINIA  22601
(Individually and collectively, "Borrower")

FIRST UNION National Bank
201 S. Jefferson Street
Roanoke, Virginia  24011
(Hereinafter referred to as the "Bank")


Borrower promises to pay to the order of Bank, in lawful money of the United
States of America, at its office indicated above or wherever else Bank may
specify, the sum of One Million Thirty Five Thousand Dollars and No Cents
($1,035,000.00) or such sum as may be advanced and outstanding from time to
time, with interest on the unpaid principal balance at the rate and on the terms
provided in this Promissory Note (including all renewals, extensions or
modifications hereof, this "Note").

SECURITY. Borrower has granted Bank a security interest in the collateral
described in the Loan Documents including, but not limited to, real property
collateral described in that certain Deed of Trust of even date herewith.

INTEREST RATE DEFINITIONS.

LIBOR. 1-Month LIBOR Rate plus (100 basis points) ("LIBOR-Based Rate"). "LIBOR"
is the rate for U.S. dollar deposits of that many months maturity as reported on
Telerate page 3750 as of 11:00 a.m., London time, on the second London business
day before the relevant Interest Period begins (or if not so reported, then as
determined by the Bank from another recognized source or interbank quotation).

INTEREST RATE TO BE APPLIED.

INTEREST RATE. Subject to the provisions hereof, the unpaid principal balance of
this Note shall bear interest from the date hereof at the LIBOR-Based Rate, as
determined by Bank prior to the commencement of each consecutive interest period
of 1 month (each, an "Interest Period") during the term of the Note. Upon
<PAGE>
 
determination by Bank of the LIBOR-Based Rate for any Interest Period, such
LIBOR-Based Rate shall remain in effect, subject to the provisions hereof, for
the entire Interest Period until redetermined as provided above for the next
successive Interest Period.

INDEMNIFICATION. Borrower indemnifies Bank against Bank's loss or expense in
employing deposits as a consequence of (a) Borrower's failure to make any
payment when due under this Note, or (b) any payment, prepayment or conversion
of any loan on a date other than the last day of the Interest Period
("Indemnified Loss or Expense"). The amount of such Indemnified Loss or Expense
shall be determined by Bank based upon the assumption that Bank funded 100% of
that portion of the loan in the London interbank market.

DEFAULT RATE. In addition to all other rights contained in this Note, if a
Default (defined herein) occurs and as long as a Default continues, all
outstanding Obligations shall bear interest at the LIBOR-Based Rate plus 3%
("Default Rate"). The Default Rate shall also apply from acceleration until the
Obligations or any judgment thereon is paid in full.

INTEREST AND FEE(S) COMPUTATION (ACTUAL/360) . Interest and fees, if any, shall
be computed on the basis of a 360-day year for the actual number of days in the
applicable period ("Actual/360 Computation"). The Actual/360 Computation
determines the annual effective yield by taking the stated (nominal) rate for a
year's period and then dividing said rate by 360 to determine the daily periodic
rate to be applied for each day in the applicable period. Application of the
Actual/360 Computation produces an annualized effective interest rate exceeding
that of the nominal rate.

REPAYMENT TERMS. This Note shall be due and payable as set forth in the
Repayment Schedule attached hereto and made a part hereof. All remaining
principal and interest shall be due and payable on November 28, 2008.

SCHEDULED PAYMENT ADJUSTMENT. At Bank's option and with notice to Borrower, the
scheduled payment amount will increase as is necessary (i) to pay all accruals
of interest for the period and previous periods and (ii) to maintain principal
repayment according to the amortization that would have occurred if the Interest
Rate in effect on the date of this Note had remained constant. The increased
payment amount shall remain in effect for as long as the original scheduled
payment amount is insufficient to pay accrued interest and principal and shall
be further adjusted upward or downward to reflect changes in the variable
interest rate. The scheduled payment amount will not be reduced below the
original scheduled payment amount.

APPLICATION OF PAYMENTS. Monies received by Bank from any source for application
toward payment of the Obligations shall be applied to accrued interest 
<PAGE>
 
and then to principal. If a Default occurs, monies may be applied to the
Obligations in any manner or order deemed appropriate by Bank.

If any payment received by Bank under this Note or other Loan Documents is
rescinded, avoided or for any reason returned by Bank because of any adverse
claim or threatened action, the returned payment shall remain payable as an
obligation of all persons liable under this Note or other Loan Documents as
though such payment had not been made.

LOAN DOCUMENTS AND OBLIGATIONS. The term "Loan Documents" used in this Note and
other Loan Documents refers to all documents executed in connection with the
loan evidenced by this Note and any prior notes which evidence all or any
portion of the loan evidenced by this Note, and may include, without limitation,
a commitment letter that survives closing, a loan agreement, this Note, guaranty
agreements, security agreements, security instruments, financing statements,
mortgage instruments, letters of credit and any renewals or modifications,
whenever any of the foregoing are executed, but does not include swap agreements
(as defined in 11 U.S.C. 101).

The term "Obligations" used in this Note refers to any and all indebtedness and
other obligations under this Note, all other obligations under any other loan
Document(s), and all obligations under any swap agreements as defined in 11
U.S.C. 101 between Borrower and Bank whenever executed including the ISDA Master
Agreement dated March 20, 1998 between Bank and Borrower.

LATE CHARGE. If any payments are not timely made, Borrower shall also pay to
Bank a late charge equal to five percent (5%) of each payment past due for eight
(8) or more days.

Acceptance by Bank of any late payment without an accompanying late charge shall
not be deemed a waiver of Bank's right to collect such late charge or to collect
a late charge for any subsequent late payment received.

If this Note is secured by owner-occupied residential real property located
outside the state in which the office of Bank first shown above is located, the
late charge laws of the state where the real property is located shall apply to
this Note and the late charge shall be the highest amount allowable under such
laws. If no amount is stated thereunder, the late charge shall be five percent
(5%) of each payment past due for ten (10) or more days.

ATTORNEYS' FEES AND OTHER COLLECTION COSTS. Borrower shall pay all of Bank's
reasonable expenses incurred to enforce or collect any of the Obligations,
including, without limitation, reasonable arbitration, paralegals', attorneys'
and experts' fees and expenses, whether incurred without the 
<PAGE>
 
commencement of a suit, in any trial, arbitration, or administrative proceeding,
or in any appellate or bankruptcy proceeding.

USURY. Regardless of any other provision of this Note or other Loan Documents,
if for any reason the effective interest should exceed the maximum lawful
interest, the effective interest shall be deemed reduced to, and shall be, such
maximum lawful interest, and (i) the amount which would be excessive interest
shall be deemed applied to the reduction of the principal balance of this Note
and not to the payment of interest, and (ii) if the loan evidenced by this Note
has been or is thereby paid in full, the excess shall be returned to the party
paying same, such application to the principal balance of this Note or the
refunding of excess to be a complete settlement and acquittance thereof.

DEFAULT. If any of the following occurs a default ("Default") under this Note
shall exist: NONPAYMENT; NONPERFORMANCE. The failure of timely payment or
performance of the Obligations or Default under this Note or any other Loan
Documents. FALSE WARRANTY. A warranty or representation deemed made in the Loan
Documents or furnished Bank in connection with the loan evidenced by this Note
proves materially false, or if of a continuing nature, becomes materially false.
CROSS DEFAULT. At Bank's option, any default in payment or performance of any
obligation under any other loans, contracts or agreements of Borrower, any
Subsidiary or Affiliate of Borrower, any general partner of or the holder(s) of
the majority ownership interests of Borrower with Bank or its affiliates
("Affiliate" shall have the meaning as defined in 11 U.S.C. 101, except that the
term "debtor" therein shall be substituted by the term "Borrower" herein;
"Subsidiary" shall mean any corporation of which more than 50% of the issued or
outstanding voting stock is owned directly or indirectly by Borrower).

of, termination of existence of, loss of good standing status by, appointment of
a receiver for, assignment for the benefit of creditors of, or commencement of
any bankruptcy or insolvency proceeding by or against Borrower, its Subsidiaries
or Affiliates, if any, or any general partner of or the holder(s) of the
majority ownership interests of Borrower, or any party to the Loan Documents.
MATERIAL CAPITAL STRUCTURE OR BUSINESS ALTERATION. Without prior written consent
of Bank, (i) a material alteration in the kind or type of Borrower's business or
that of Borrower's Subsidiaries or Affiliates, if any; (ii) the sale of more
than 50% of the Borrower's outstanding stock or voting power of or in a single
transaction or a series of transactions; (iii) the acquisition of substantially
all of the business or assets or more than 50% of the outstanding stock or
voting power of any other entity; or (iv) should any Borrower, or any of
Borrower's Subsidiaries or Affiliates, or any guarantor enter into any merger or
consolidation.

Documents, Bank may at any time thereafter, take the following actions: BANK

without notice. ACCELERATION UPON DEFAULT. Accelerate the maturity of this Note

Borrower dated December 10, 1996, and all modifications and amendments thereof
(the "Credit Agreement") are true and correct as of the date of the Note; and at
all times, Borrower shall comply with the provisions of Article V of the Credit
Agreement. Borrower's obligation to comply with such provisions shall continue
notwithstanding the satisfaction in full of all obligations referred to in the
Credit Agreement.

WAIVERS AND AMENDMENTS. No waivers, amendments or modifications of this Note and
other Loan Documents shall be valid unless in writing and signed by an officer
of Bank. No waiver by Bank of any Default shall operate as a waiver of any other
Default or the same Default on a future occasion. Neither the failure nor any
delay on the part of Bank in exercising any right, power, or remedy under this
Note and other Loan Documents shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or remedy.

protest, notice of dishonor, demand for payment, notice of intention to
accelerate maturity, notice of acceleration of maturity, notice of sale and all

   organized, validly existing, and in good standing under the laws of the State
   of Delaware and is validly existing and in good standing in all states in
   which Borrower is doing business. Borrower has the full power and authority

   performed by Borrower, have been duly authorized by all necessary action by

   articles of organization, operating agreement, or any other agreement or
   other instrument binding upon Borrower or (b) any law, governmental
   regulation, court decree, or order applicable to Borrower.

   FINANCIAL INFORMATION. Each financial statement of Borrower supplied to
   Lender truly and completely disclosed Borrower's financial condition as of
   the date of the statement, and there has been no material adverse change in
   Borrower's financial condition subsequent to the date of the most recent
   financial statement supplied to Lender. Borrower has no material contingent
   obligations except as disclosed in such financial statements.

   LEGAL EFFECT. This Agreement constitutes, and any instrument or agreement
   required hereunder to be given by Borrower when delivered will constitute,
   legal, valid and binding obligations of Borrower enforceable against Borrower
   in accordance with their respective terms.

   PROPERTIES. Except as contemplated by this Agreement or as previously
   disclosed in Borrower's financial statements or in writing to Lender and as
   accepted by Lender, and except for property tax liens for taxes not presently
   due and payable, Borrower owns and has good title to all of Borrower's
   properties free and clear of all Security Interests, and has not executed any
   security documents or financing statements relating to such properties. All
   of Borrower's properties are titled in Borrower's legal name, and Borrower
   has not used, or filed a financing statement under, any other name for at
   least the last five (5) years.

   HAZARDOUS SUBSTANCES. The terms "hazardous substance," "disposal,""release,"
   and "threatened release," as used in this Agreement, shall have the same

   any of the foregoing. Except as disclosed to and acknowledged by Lender in
   writing, Borrower represents and warrants that: (a) During the period of
   Borrower's ownership of the properties, there has been no use, generation,
   manufacture, storage, treatment, disposal, release or threatened release of
   any hazardous waste or substance by any person on, under, about or from any
   of the properties. (b) Borrower has no knowledge of, or reason to believe
   that there has been (i) any use, generation, manufacture, storage, treatment,
   disposal, release, or threatened release of any hazardous waste or substance
   on, under, about or from the properties by any prior owners or occupants of
   any of the properties, or (ii) any actual or threatened litigation or claims
   of any kind by any person relating to such matters. (c) Neither Borrower nor
   any tenant, contractor, agent or other authorized user of any of the
   properties shall use, generate, manufacture, store, treat, dispose of, or
   release any hazardous waste or substance on, under, about or from any of the

   applicable federal, state, and local laws, regulations, and ordinances,
   including without limitation those laws, regulations and ordinances described
   above. Borrower authorizes Lender and its agents to enter upon the properties
   to make such inspections and tests as Lender may deem appropriate to
   determine compliance of the properties with this section of the Agreement.
   Any inspections or tests made by Lender shall be at Borrower's expense and
   for Lender's purposes only and shall not be construed to create any
   responsibility or liability on the part of Lender to Borrower or to any other
   person. The representations and warranties contained herein are based on
   Borrower's due diligence in investigating the properties for hazardous waste
   and hazardous substances. Borrower hereby (a) releases and waives any future
   claims against Lender for indemnity or contribution in the event Borrower
   becomes liable for cleanup or other costs under any such laws, and (b) agrees
   to indemnify and hold harmless Lender against any and all claims, losses,
   liabilities, damages, penalties, and expenses which Lender may directly or
   indirectly sustain or suffer resulting from a breach of this section of the
   Agreement or as a consequence of any use, generation, manufacture, storage,
   disposal, release or threatened release of a hazardous waste or substance on
   the properties. The provisions of this section of the Agreement, including
   the obligation to indemnify, shall survive the payment of the indebtedness
   and the termination or expiration of this Agreement and shall not be affected
   by Lender's acquisition of any interest in any of the properties, whether by
   foreclosure or otherwise.

   LITIGATION AND CLAIMS. No litigation, claim, investigation, administrative
   proceeding or similar action (including those for unpaid taxes) against
   Borrower is pending or threatened, and no other event has occurred which may
   materially adversely affect Borrower's financial condition or properties,
   other than litigation, claims, or other events, if any, that have been

   the ordinary course of business and for which adequate reserves have been
   provided.

   Borrower has not entered into or granted any Security Agreements, or
   permitted the filing or attachment of any Security Interests on or affecting
   any of the Collateral directly or indirectly securing repayment of Borrower's
   Loan and Note, that would be prior or that may in any way be superior to
   Lender's Security interests and rights in and to such Collateral.

   BINDING EFFECT. This Agreement, the Note, all Security Agreements directly or
   indirectly securing repayment of Borrower's Loan and Note and all of the
   Related Documents are binding upon Borrower as well as upon Borrower's

applicable law, to charge or setoff all sums owing on the Indebtedness against 
any and all such accounts.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default 
under this Agreement:

   DEFAULT ON INDEBTEDNESS. Failure of Borrower to make any payment when due on
   the Loans.

   OTHER DEFAULTS. Failure of Borrower or any Grantor to comply with or to
   perform when due any other term, obligation, covenant or condition contained
   in this Agreement or in any of the Related Documents, or failure of Borrower
   to comply with or to perform any other term, obligation, covenant or
   condition contained in any other agreement between Lender and Borrower.

   ENVIRONMENTAL DEFAULT. Failure of any party to comply with or perform when
   due any term, obligation, covenant or condition contained in an environmental
   agreement executed in connection with any Loan.

   DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor default
   under any loan, extension of credit, security agreement, purchase or sales
   agreement, or any other agreement, in favor of any other creditor or person
   that may materially affect any of Borrower's property or Borrower's or any
   Grantor's ability to repay the Loans or perform their respective obligations
   under this Agreement or any of the Related Documents.

   FALSE STATEMENTS. Any warranty, representation or statement made or furnished
   to Lender by or on behalf of Borrower or any Grantor under this Agreement or
   the Related Documents is false or misleading in any material respect at the
   time made or furnished, or becomes false or misleading at any time
   thereafter.

   DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related Documents
   ceases to be in full force and effect (including failure of any Security
   Agreement to create a valid and perfected Security Interest) at any time and
   for any reason.

   DEATH OR INSOLVENCY. The dissolution (regardless of whether election to
   continue is made), any member withdraws from Borrower, or any other
   termination of Borrower's existence as a going business or the death of any
   member, the Insolvency of Borrower, the appointment of a receiver for any
   part of Borrower's property, any assignment for the benefit of creditors, any
   type of creditor workout, or the commencement of any proceeding under any
   bankruptcy or insolvency laws by or against Borrower.

   CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or forfeiture
   proceedings, whether by judicial proceeding, self-help, repossession or any
   other method, by any creditor of Borrower, any creditor of any Grantor
   against any collateral securing the Indebtedness, or by any governmental
   agency. This includes a garnishment, attachment, or levy on or of any of
   Borrower's deposit accounts with Lender. However, this Event of Default shall
   not apply if there is a good faith dispute by Borrower or Grantor, as the
   case may be, as to the validity or reasonableness of the claim which is the
   basis of the creditor or forfeiture proceeding, and if Borrower or Grantor
   gives Lender written notice of the creditor or forfeiture proceeding and
   furnishes reserves or a surety bond for the creditor or forfeiture proceeding
   satisfactory to Lender.

   EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with respect
   to any Guarantor of any of the Indebtedness or any Guarantor dies or becomes
   incompetent, or revokes or disputes the validity of, or liability under, any
   Guaranty of the Indebtedness. Lender, at its option, may, but shall not be
   required to, permit the Guarantor's estate to assume unconditionally the
   obligations arising under the guaranty in a manner satisfactory to Lender,
   and, in doing so, cure the Event of Default.

   ADVERSE CHANGE. A material adverse change occurs in Borrower's financial
   condition, or Lender believes the prospect of payment or performance of the
   Indebtedness is impaired.

   RIGHT TO CURE. If any default, other than a Default on Indebtedness, is
   curable and if Borrower or Grantor, as the case may be, has not been given a
   notice of a similar default within the preceding twelve (12) months, it may
   be cured (and no Event of Default will have occurred) if Borrower or Grantor,
   as the case may be, after receiving written notice from Lender demanding cure
   of such default: (a) cures the default within thirty (30) days; or (b) if the
   cure requires more than thirty (30) days, immediately initiates steps which
   Lender deems in Lender's sole discretion to be sufficient to cure the default
   and thereafter continues and completes all reasonable and necessary steps
   sufficient to produce compliance as soon as reasonably practical.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except where
otherwise provided in this Agreement or the Related Documents, all commitments 
and obligations of Lender under this Agreement or the Related Documents or any 
other agreement immediately will terminate and, at Lender's option, all 
Indebtedness immediately will become due and payable, all without notice of any 
kind to Borrower, except that in the case of an Event of Default of the type 
described in the "Insolvency" subsection above, such acceleration shall be 
automatic and not optional. In addition, Lender shall have all the rights and 
remedies provided in the Related Documents or available at law, in equity, or 
otherwise. Except as may be prohibited by applicable law, all of Lender's rights
and remedies shall be cumulative and may be exercised singularly or 
concurrently. Election by Lender to pursue any remedy shall not exclude pursuit 
of any other remedy, and an election to make expenditures or to take action to 
perform an obligation of Borrower or of any Grantor shall not affect Lender's 
right to declare a default and to exercise its rights and remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of 
this Agreement:

   AMENDMENTS. This Agreement, together with any Related Documents, constitutes
   the entire understanding and agreement of the parties as to the matters set

   Lender may provide, without any limitation whatsoever, to any one or more
   purchasers, or potential purchasers, any information or knowledge Lender may
   have about Borrower or about any other matter relating to the Loan, and
   Borrower hereby waives any rights to privacy it may have with respect to such
   matters. Borrower additionally waives any and all notices of sale of
   participation interests, as well as all notices of any repurchase of such
   participation interests. Borrower also agrees that the purchasers of any such

   claim, cause of action or offset against Lender within thirty (30) days after

   parties, or out of any other matter whatsoever related to this Agreement or
   the Related Documents, but excluding any claim or liability which arises as a
   direct result of Lender's gross negligence or willful misconduct. This
   Indemnity shall survive full repayment and satisfaction of the Indebtedness
   and termination of this Agreement.

   COUNTERPARTS. This Agreement may be executed in multiple counterparts, each
   of which, when so executed, shall be deemed an original, but all such
   counterparts, taken together, shall constitute one and the same Agreement.

     notice to the other parties, specifying that the purpose of the notice to
     change the party's address. To the extent permitted by applicable law, if
     there is more than one Borrower, notice to any Borrower will constitute 
     notice to all Borrowers. For notice purposes, Borrower will keep Lender 
     informed at all times of Borrower's current address(es).

     SEVERABILITY. If a court of competent jurisdiction finds any provision of
     this Agreement to be invalid or unenforceable as to any person
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances. If feasible, any
     such offending provision shall be deemed to be modified to be within the
     limits of enforceability or validity; however, if the offending provision

     limitation any representation, warranty or covenant, the word "Borrower" as
     used herein shall include all subsidiaries and affiliates of Borrowers

     Agreement be construed to require Lender to make any Loan or other
     financial accommodation to any subsidiary or affiliate of Borrower.

     SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or on
     behalf of Borrower shall bind its successors and assigns and shall inure

     this Agreement or in any certificate or other instrument delivered by
     Borrower to Lender under this Agreement shall be considered to have been
     relied upon by Lender and will survive the making of the Loan and delivery
     to Lender of the Related Documents, regardless of any investigation made by
     Lender or on Lender's behalf.

     TIME IS OF THE ESSENCE. Time is of the essence in the performance of this
     Agreement.

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender. No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender
     of a provision of this Agreement shall not prejudice or constitute a waiver
     of Lender's right otherwise to demand strict compliance with that provision
     or any other provision of this Agreement. No prior waiver by Lender, nor
     any course of dealing between Lender and Borrower, or between Lender and
     any Grantor, shall constitute a waiver of any of Lender's rights or of any
     obligations of Borrower or of any Grantor as to any future transactions.
     Whenever the consent of Lender is required under this Agreement, the
     granting of such consent by Lender in any instance shall not constitute
     continuing consent in subsequent instances where such consent is required,
     and in all cases such consent may be granted or withheld in the sole
     discretion of Lender.

================================================================================


       (c) Acceptance of the completed improvements by Lender and Borrower.

     Construction Default. If Borrower fails in any respect to comply with the
     provisions of this Agreement or if construction ceases before completion
     regardless of the reason, Lender, at its option, may refuse to make further
     Advances, may accelerate the indebtedness under the terms of the Note, and
     without thereby impairing any of its rights, powers, or privileges, may
     enter into possession of the construction site and perform or cause to be
     performed any and all work and labor necessary to complete the
     improvements, substantially in accordance with the Plans and
     Specifications.

     Damage or Destruction. If any of the Property or Improvements is damaged or
     destroyed by casualty of any nature, within sixty (60) days thereafter
     Borrower shall restore the Property and improvements to the condition in
     which they were before such damage or destruction with funds other than
     those in the Loan Fund. Lender shall not be obligated to make disbursements
     under this Agreement until such restoration has been accomplished.

     covenant in this Agreement, Lender may require Borrower to furnish, within
     ten (10) days after delivery of a written request, adequate security to
     eliminate, reduce, or indemnity Lender against, such danger.  In addition,
     upon such occurrence, Lender in its sole discretion may advance funds or 
     agree to undertake to advance funds to any party to eliminate, reduce, or 
     indemnify Lender against such danger or to complete the Project.  All sums
     paid by Lender pursuant to such agreements or undertakings shall be for
     Borrower's account and shall be without prejudice to Borrower's rights, if
     any, to receive such funds from the party to whom paid.  All sums expended
     by Lender in the exercise of its option to complete the Project or protect
     Lender's interests shall be payable to Lender on demand together with
     interest from the date of the Advance at the rate applicable to the Loan.
     In addition, any Advance of funds under this Agreement, including without
     limitation direct disbursements to the General Contractor or other parties
     in payment of sums due under the Construction Contract, shall be deemed to
     have been expended by or on behalf of Borrower and to have been secured by
     Lender's Mortgage or Deed of Trust, if any, on the Property.

LIMITATION OF RESPONSIBILITY.  The making of any Advance by Lender shall not
constitute or be interpreted as either (a) an approval or acceptance by Lender
of the work done through the date of the Advance, or (b) a representation or
indemnity by Lender to any party against any deficiency or defect in the work or
against any breach of any contract.  Inspections and approvals of the Plans and
Specifications, the Improvements, the workmanship and materials used in the
Improvements, and the exercise of any other right of inspection, approval, or
inquiry granted to Lender in this Agreement are acknowledged to be solely for
the protection of Lender's interests, and under no circumstances shall they be
construed to impose any responsibility or liability of any nature whatsoever on
Lender to any party.  Neither Borrower nor any contractor, subcontractor,
materialmen, laborer, or any other person shall rely, or have any right to rely,
upon Lender's determination of the appropriateness of any Advance.  No
disbursement or approval by Lender shall constitute a representation by Lender
as to the nature of the Project, its construction, or its intended use for
Borrower or for any other person, nor shall it constitute an indemnity by Lender
to Borrower or to any other person against any deficiency or defects in the
Project or against any breach of any contract.

     Borrower, provide Lender with surety bond issued by a surety acceptable to
     Lender sufficient to release the claim of lien or deposit with Lender an
     amount satisfactory to Lender for the possibility that the contest will be
     unsuccessful.  If Borrower fails to remove any lien on the Property or
     Improvements or provide a bond or deposit pursuant to this provision,
     Lender may pay such lien, or may contest the validity of the lien, and
     Borrower shall pay all costs and expenses of such contest, including
     Lender's reasonable attorneys' fees.

     Borrower shall not be required to pay and discharge any such indebtedness,
     obligation, or claim so long as (a) its legality shall be contested in good
     faith by appropriate proceedings, (b) the Indebtedness, obligation, or
     claim does not become a lien or charge upon the Property or Improvements,
     and (c) Borrower shall have established on its books adequate reserves with
     respect to the amount contested in accordance with generally accepted
     accounting practices.  If the indebtedness, obligation, or claim does 
     become a lien or charge upon the Property or Improvements, Borrower shall
     remove the lien or charge as provided in the preceding paragraph.

     provisions, set forth in this Agreement and in all other instruments and

     with any agreement.

     other than minor changes involving no extra cost, must be in writing
     signed by Borrower and the architect, and delivered to Lender for it's
     approval. Borrower will not permit the performance of any work pursuant
     to any change order or modification of the Construction Contract or any
     subcontract without the written approval of Lender. Borrower will obtain
     any required permits or authorizations from governmental authorities
     having jurisdiction before approving or requesting a new change order.

     PURCHASE OF MATERIALS; CONDITIONAL SALES CONTRACTS. No materials,
     equipment, fixtures, or articles of personal property placed in or
     incorporated into the Project shall be purchased or installed under any

     work or materials do not conform to the approved Plans and Specifications
     or sound building practices, or otherwise depart from any of the
     requirements of this Agreement, Lender may require the work to be stopped
     and withhold disbursements until the matter is corrected. In such event,
     Borrower will promptly correct the work to Lender's satisfaction. No such
     action by Lender will affect Borrower's obligation to complete the
     Improvements on or before the Completion Date. Lender is under no duty to
     supervise or inspect the construction or examine any books and records. Any
     inspection or examination by Lender is for the sole purpose of protecting
     Lender's security and preserving Lender's rights under this Agreement. No
     default of Borrower will be waived by any inspection by Lender. In no event
     will any inspection by Lender be a representation that there has been or
     will be compliance with the Plans and Specifications or that the
     construction is free from defective materials or workmanship.

     INDEMNITY. Borrower shall indemnify and hold Lender harmless from any and
     all claims asserted against Lender or the Property by any person, entity,
     or governmental body, or arising out of or in connection with the
     Property, Improvements, or Project. Lender shall be entitled to appear in
     any action or proceeding to defend itself against such claims, and all
     costs incurred by Lender in connection with such defense, including
     attorney's fees, shall be paid by Borrower to Lender. Lender shall, in

     purposes of this indemnification. All amounts paid by Lender under this
     paragraph shall be secured by Lender's Mortgage or Deed of Trust, if any,
     on the Property, shall be deemed an additional principal Advance under
     the Loan, payable upon demand, and shall bear interest at the rate
     applicable to the Loan.

     the public that Lender is the construction lender of the Project. Lender

letter for the Loan to Borrower.

     to pay any fees to Lender or any costs and expenses relating to the Loan
     or the commitment shall survive the execution and delivery of this

     perform any such obligation shall constitute a default under this
     Agreement.

and hereby assigns, conveys, delivers, pledges, and transfers to Lender all

     any time thereafter.
     
     DEFECTIVE COLLATERALIZATION.  This agreement or any of the Related

     or by any governmental agency. This includes a garnishment, attachment,
     or levy on or of any of Borrower's deposit accounts with Lender. However,
     this event of Default shall not apply if there is a good faith dispute by
     Borrower or Grantor, as the case may be, as to the validity or
     reasonableness of the claim which is the basis of the creditor or

     respect to any Guarantor of any of the indebtedness or any Guarantor dies
     or becomes incompetent, or revokes or disputes the validity of, or

     may, but shall not be required to, permit the Guarantor's estate to

     curable and if Borrower or Grantor, as the case may be, has not been
     given a notice of a similar default within the preceding twelve (12)
     months, it may be cured (and no Event of Default will have occurred) if
     Borrower or Grantor, as the case may be, after receiving written notice
     from Lender demanding cure of such default: (a) cures the default within
     thirty (30) days; or (b) if the cure requires more than thirty (30) days,

     seized, or appropriated without compensation, and Borrower does not within
     thirty (30) days after such condemnation, seizure, or appropriation,
     initiate and diligently prosecute appropriate action to contest in good
     faith the validity of such condemnation, seizure, or appropriation.

EFFECT OF AN EVENT OF DEFAULT; REMEDIES. Upon the occurrence of any Event of
Default and at any time thereafter, Lender may, at its option, but without any
obligation to do so, and in addition to any other right Lender may have ,do any

it may take any and all actions necessary in its judgment to complete
construction of the Improvements, including but not limited to making changes in
the Plans and Specifications, work, or materials and entering into, modifying or
terminating any contractual arrangements, subject to Lender's right at any time
to discontinue any work without liability.  If Lender elects to complete the
Improvements, it will not assume any liability to Borrower or to any other
person for completing the improvements or for the manner or quality of
construction of the improvements, and Borrower expressly waives any such
liability. Borrower irrevocably appoints Lender as its attorney-in-fact, with
full power of substitution, to complete its improvements, at Lender's option,
either in Borrower's name or in its own name. In any event, all sums expended by
Lender in completing its construction of the improvements will be considered to
have been disbursed to Borrower and will be secured by the collateral for the
Loan. Any such sums that cause the principal amount of the Loan to exceed the
face amount of the Note will be considered to be an additional Loan to Borrower,
bearing interest at the Note rate and being secured by the collateral. For these
purposes, Borrower assigns to Lender all of its right, title and interest in and
to the Project Documents; however Lender will not have any obligation under the
Project Documents unless Lender expressly hereafter agrees to assume such
obligations in writing. Lender will have the to exercise any rights of Borrower
under the Project Documents upon the occurrence of an Event of Default. All
rights, powers, and remedies of Lender under this Agreement are cumulative and
alternative, and are in addition to all rights which Lender may have under
applicable law.
