                                  THE COMPANY

     The Company is a leading distributor of fasteners and other small parts and
provider of related inventory procurement and management services to original
equipment manufacturers ("OEMs") on a worldwide basis. Fasteners and small
parts include screws, bolts, nuts, washers, pins, rings, fittings, springs,
electrical connectors and similar parts. Pentacon was founded in March 1997 to
aggressively pursue the consolidation of the highly-fragmented fastener
distribution industry. According to an industry study by The Freedonia Group,
Inc., sales by fastener manufacturers in 1996 were approximately $8.0 billion in
the United States and $25.0 billion globally. The United States fastener market
is estimated to have over 1,900 distributors. The Company believes that the OEM
fastener and small part distribution industry is in the early stages of
consolidation, and the Company plans to lead the consolidation of the industry.
The Company believes that its broad selection of fasteners and small parts, high
quality services, professional management team, and strong competitive position
as a publicly-owned fastener distributor focused on the OEM market, will allow
it to be the leading consolidator.

     Fasteners and other small parts constitute a majority of the total number
of parts needed by an OEM to manufacture many products, but represent only a
small fraction of the total materials cost. The cost for an OEM to internally
manage its inventory of fasteners and small parts is relatively high due to (i)
the large number of fasteners and other small parts in the inventory, (ii) the
risk of interruptions for just-in-time ("JIT") manufacturing operations, and
(iii) the need to perform quality assurance testing of the fasteners and small
parts. The Company believes that OEMs are increasingly outsourcing their
fastener and other small parts inventory procurement and management needs to
distributors in order to focus on their core manufacturing businesses and to
reduce costs. To further reduce costs, many manufacturers are seeking to
consolidate the number of distributors they use and are selecting national
distributors with extensive product lines who can also provide inventory-related
services. To capitalize on these trends, the Company offers a broad array of
fasteners and small parts and provides a variety of related procurement and
inventory management services, including inventory management information
systems ("MIS") and reports, JIT delivery, quality assurance, advisory
engineering services, component kit production and delivery, small component
assembly and electronic data interchange ("EDI").
   
     Upon consummation of the Offering, Pentacon will acquire the five Founding
Companies, which have been in business an average of 25 years and which had
combined net sales of $120.0 million in 1996 and $112.8 million for the nine
months ended September 30, 1997. While total U.S. sales of fasteners have
increased at a compound annual rate of approximately 4.1% during the four years
ended December 31,
    
                                       3
<PAGE>
1996, the combined net sales of the Founding Companies have increased at a
compound annual rate of approximately 14.8% per year over the same period. The
Company believes that it has generated superior growth primarily by expanding
the breadth of its product offerings and value-added services, which has allowed
the Founding Companies to increase market share at existing customers and
attract new customers.

     The Company operates a national sales and distribution network with 24
facilities in 14 states. Through this network and international agents, the
Company serves more than 2,600 customers in over 25 countries. These customers
manufacture a wide variety of products including diesel engines, locomotives,
power turbines, motorcycles, telecommunications equipment, refrigeration
equipment and aerospace equipment. The Company's largest customers include
Cummins Engine Company, General Electric Corporation, Harley-Davidson, Inc., the
Hughes Aircraft subsidiary of General Motors Corporation, The Trane Company,
Lockheed Martin Corporation, and The Boeing Company. The Company anticipates
that its ability to provide a comprehensive product line and offer related
services over a broad geographic area will assist the Company in obtaining
additional nationwide accounts with large national and international OEMs.

                               BUSINESS STRATEGY

     The Company intends to become the leading fastener and small parts
distributor on a worldwide basis. Key elements of the Company's strategy to
achieve its objective are:

          PROVIDE VALUE-ADDED SERVICES.  The Company seeks to continually
     develop and supply inventory-related services designed to reduce its
     customers' operating costs. Quality assurance, JIT delivery and component
     kit production are examples of such services currently provided by the
     Company to its customers. By supplying such services, the Company becomes
     more integrated into the customers' internal manufacturing processes and is
     better able to anticipate its customers' needs, which the Company believes
     results in improved profitability and customer retention.
   
          DELIVER SUPERIOR CUSTOMER SERVICE.  OEMs and other fastener customers
     choose fastener suppliers based, in significant part, on the quality of the
     service supplied. The Company believes that its superior customer service
     depends on its well-trained, technically competent workforce and that its
     workforce provides an advantage over other fastener distributors. The
     Company intends to review the training and operating practices at each
     Founding Company to identify and adopt those "best practices" in
     providing customer service that can be successfully implemented throughout
     its operations. As part of its commitment to superior customer service, the
     Company intends to have each of its operating companies certified under or
     be in compliance with the International Standards Organization ("ISO")
     standards for distribution companies. Two of the Founding Companies are
     already ISO-9002 certified. The other Founding Companies have commenced
     application for ISO-9002 or similar certification, and the Company expects
     the substantial majority of its currently uncertified locations to be ISO
     compliant or certified in 1998.

          ACCELERATE INTERNAL SALES GROWTH.  One of the primary goals of the
     Company is to accelerate internal growth by both expanding the range of
     products and services provided to existing customers and aggressively
     pursuing new customers domestically and abroad. The Company believes it
     will be able to expand sales to existing customers by capitalizing on (i)
     the diverse products and the marketing expertise of the Founding Companies,
     (ii) cross-selling opportunities across the Company's customer base, and
     (iii) the additional financial resources that are expected to be available
     after consummation of the Offering. The Company believes its broad
     geographic coverage will present opportunities to capture additional
     business from existing customers that operate on a national and
     international basis. The Company intends to implement a company-wide
     marketing program and to adopt the "best practices" used by the Founding
     Companies to identify, obtain and maintain new customers.
    
          EXPAND OPERATING MARGINS.  The Company believes that the combination
     of the Founding Companies will provide significant opportunities to
     increase its profitability. The key components of this strategy are to
     increase operating efficiencies and centralize appropriate administrative
     functions.

                                       4
<PAGE>
     The Company intends to use its increased purchasing power to improve
     contractual relationships and gain volume discounts from its suppliers. The
     Company also intends to improve productivity through enhanced inventory
     management procedures, increased utilization of the Company's laboratories
     and distribution facilities, and the consolidation of information systems
     and employee benefits.
   
          AGGRESSIVELY PURSUE ACQUISITIONS.  The Company believes that the
     fastener distribution industry is highly fragmented and in the early stages
     of consolidation. The Company intends to pursue an aggressive acquisition
     program targeting fastener distributors that will help the Company increase
     its presence in markets it currently serves, sell to new markets, develop
     new customer relationships with major OEMs, increase its presence in the
     international markets and expand its range of products and services. The
     Company believes there is a significant number of acquisition candidates
     available and that it will be regarded as an attractive acquiror due to its
     position as an industry leader, its ability to offer cash and/or
     publicly-traded stock for acquisitions, and the potential for improved
     growth and profitability as part of the Company. The Company intends to
     file a registration statement covering 3,350,000 additional shares of
     Common Stock under the Securities Act for its use in connection with future
     acquisitions.

(1) The pro forma combined income statement data assumes that the Acquisitions
    and Offering were closed on January 1, 1997 (except for Capitol, whose
    historical results for nine months from December 1, 1996 to August 31, 1997
    were used for pro forma information), and are not necessarily indicative of
    the results the Company would have obtained had these events actually then
    occurred or of the Company's future results. During the periods presented
    above, the Founding Companies were not under common control or management
    and, therefore, the data presented may not be comparable to or indicative of
    post-combination results to be achieved by the Company. The pro forma
    combined income statement data are based on available information and
    certain assumptions that management deems appropriate and should be read in
    conjunction with the other financial statements and notes thereto included
    elsewhere in this Prospectus. Neither the potential cost savings from
    consolidating certain operational and administrative functions nor the costs
    of corporate overhead, other than salaries of executive officers, have been
    included in the pro forma combined financial information.

(2) The pro forma combined income statement data reflects an aggregate of
    approximately $2,146,000 in pro forma reductions in salary and benefits of
    the owners of the Founding Companies to which they have agreed
    prospectively, and $450,000 in pro forma increases in salary and benefits to
    the corporate management and $119,000 of expense reductions for the effect
    of revisions of certain lease agreements between certain stockholders of the
    Founding Companies and those Founding Companies. See "Certain
    Transactions."

(3) Reflects amortization of the goodwill for the nine month period to be
    recorded as a result of the Acquisitions over a 40-year period and computed
    on the basis described in the Notes to the Unaudited Pro Forma Combined
    Financial Statements.

(4) Includes interest income (expense) and other income (expense); net pro forma
    interest expense reflects a reduction in interest of $1,073,915 related to
    repayment of indebtedness with the proceeds from the Offering. See "Use of
    Proceeds."
   
(5) Consists of (i) 6,720,000 shares to be issued to the owners of the Founding
    Companies, (ii) 450,000 shares issued to the management of Pentacon, (iii)
    2,380,000 shares issued to MGCV, (iv) 3,773,585 shares to be sold in the
    Offering, (v) the dilutive effect of warrants to purchase 50,000 shares at
    an exercise price equal to the lesser of $8.00 or 60% of the initial public
    offering price per share using the treasury stock method and assuming an
    initial public offering price of $   per share. Subsequent to September 30,
    1997 (i) options to purchase 370,000 shares at the initial public offering
    price were issued and are currently outstanding and (ii) options to purchase
    600,000 shares at the initial public offering price are expected to be
    granted to the Company's employees upon consummation of the Offering.
    
(6) The pro forma combined balance sheet data assume that the Acquisitions were
    closed on September 30, 1997. The pro forma combined balance sheet data is
    based upon available information and certain assumptions that management
    deems appropriate and should be read in conjunction with the other financial
    statements and notes thereto included elsewhere in this Prospectus.

(7) Reflects the closing of the Offering at an assumed price of $       per
    share and the Company's application of the net proceeds therefrom to fund
    the cash portion of the purchase price of the Acquisitions and to repay
    indebtedness of the Founding Companies. See "Use of Proceeds" and
    "Certain Transactions."

(8) Includes $28,662,387 for the obligation to pay the cash portion of the
    purchase price for the Founding Companies.

        SUMMARY INDIVIDUAL FOUNDING COMPANY AND COMBINED FINANCIAL DATA

     The following table presents summary historical financial data for the
Founding Companies and Pentacon and Summary Pro Forma Combined Financial Data
for the stated periods. The historical income from operations has not been
adjusted for the anticipated increased costs associated with the Company's new
corporate management and with being a public company or take into account the
increase in income attributable to the compensation differential, the rent
differential, and potential cost savings from consolidating certain operational
or administrative functions. The summary unaudited pro forma combined financial
data for the Company in the table below is adjusted for (i) the effects of the
Acquisitions, (ii) the effects of certain pro forma adjustments to the
historical financial statements described below and (iii) the consummation of
the Offering. The Company has adopted a fiscal year-end of September 30. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Introduction."

THIS PROSPECTUS CONSTITUTE CAUTIONARY STATEMENTS IDENTIFYING IMPORTANT FACTORS
WITH RESPECT TO ANY SUCH FORWARD-LOOKING STATEMENTS, INCLUDING CERTAIN RISKS AND
UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM THOSE IN
SUCH FORWARD-LOOKING STATEMENTS.

ABSENCE OF COMBINED OPERATING HISTORY; RISKS OF INTEGRATING FOUNDING COMPANIES

     Pentacon was founded in 1997 but has conducted no operations other than in
connection with the Offering and the Acquisitions. Pentacon has not generated
any sales to date. The Founding Companies have been operating as separate
independent entities, and there can be no assurance that the Company will be
able to integrate the operations of these businesses successfully or to
institute the necessary systems and procedures, including accounting and
financial reporting systems, to manage the combined enterprise on a profitable
basis. The Company's senior management group has only limited experience working
together and there can be no assurance that the management group will be able to
manage the combined entity or to implement effectively the Company's acquisition
and internal growth operating strategies. The pro forma combined historical
financial results of the Founding Companies cover periods when the Founding
Companies and Pentacon were not under common control or management and may not
be indicative of the Company's future financial or operating results. Among the
issues to be considered in combining the Founding Companies are the different
objectives of, and accounting methodologies used by, private as opposed to
public companies, such as the level of scrutiny imposed by management on
business deductions such as salaries and benefits. The inability of the Company
to integrate the Founding Companies successfully would have a material adverse
effect on the Company's business, financial condition and results of operations
and would make it unlikely that the Company's acquisition program will be
successful. See "Business -- Strategy" and "Management."

RISKS RELATED TO THE COMPANY'S ACQUISITION STRATEGY

     The Company's strategy for growth significantly relies on the acquisition
of additional fastener distributors. The Company expects to face competition for
acquisition candidates, which may limit the number of acquisition opportunities
and may lead to higher acquisition prices. There can be no assurance that the
Company will be able to identify, acquire or profitably manage additional
businesses or to integrate successfully any acquired businesses into the Company
without substantial costs, delays or other operational or financial
difficulties. Further, acquisitions (including the acquisition of the Founding
Companies) involve a number of special risks, including failure of the acquired
business to achieve expected results, diversion of management's attention,
failure to retain key personnel and customers of the acquired business and risks
associated with unanticipated conditions, events or liabilities, some or all of
which could have a material adverse effect on the Company's business, financial
condition and results of operations. In addition, there can be no assurance that
the Founding Companies or other businesses acquired in the future will achieve
anticipated net sales and earnings. See "Business -- Strategy."

CAPITAL REQUIREMENTS

     The Company's acquisition strategy will require substantial capital. The
Company currently intends to finance future acquisitions by using shares of its
Common Stock for all or a portion of the consideration to be paid. If the Common
Stock does not maintain a sufficient market value, or if potential acquisition

                                       10
<PAGE>
candidates are otherwise unwilling to accept Common Stock as part of the
consideration for the sale of their businesses, the Company may be required to
utilize more of its cash resources, if available, in order to initiate and
maintain its acquisition program. If the Company does not have sufficient cash
resources, its growth could be limited unless it is able to obtain additional
capital through debt or equity financings. The Company intends to obtain a
commitment for a bank line of credit of approximately $45 million for working
capital and acquisitions contingent upon consummation of the Offering. However,
there can be no assurance that the Company will be able to obtain any additional
financing it may need for acquisitions on terms that the Company deems
acceptable. See "Use of Proceeds" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Combined Liquidity and
Capital Resources."

RISKS RELATED TO INTERNAL GROWTH AND OPERATING STRATEGIES

     Although the Company intends to seek to improve the profitability of the
Founding Companies and any subsequently acquired businesses by various means,
including realizing overhead and purchasing efficiencies and centralizing
certain administrative functions, there can be no assurances that the Company
will be able to do so. The Company's ability to increase the profitability of
the Founding Companies and any subsequently acquired businesses will be affected
by various factors, including demand for fasteners, the Company's ability to
expand the range of products and services offered by each Founding Company and
by any subsequently acquired businesses and the Company's ability to
successfully enter new markets. Many of these factors are beyond the control of
the Company, and there can be no assurance that the Company's strategies will be
successful or that it will be able to generate cash flow adequate to support its
operations and internal growth. A key component of the Company's strategy is to
operate the Founding Companies and subsequently acquired businesses on a
decentralized basis, with local management retaining responsibility for
day-to-day operations, profitability and the growth of the business. If proper
overall business controls are not implemented or if management of the Founding
Companies and subsequently acquired businesses are not successful in adopting an
integrated operating approach, this decentralized operating strategy could
result in inconsistent operating and financial practices at the Founding
Companies and subsequently acquired businesses and the Company's overall
profitability could be adversely affected. See "Business -- Strategy."

RELIANCE ON PRINCIPAL CUSTOMERS

     A significant portion of the Company's revenue has historically been
generated by a limited number of customers, although not necessarily the same
customers from year to year. For the nine months ended September 30, 1997, the
Company's ten largest customers collectively accounted for approximately 45% of
the Company's net sales. The loss of a significant customer for any reason,
including reduced production by a customer or competitive factors, could result
in a substantial loss of revenue and could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Customers."

INTEGRATION OF COMPUTER SYSTEMS AND RELIANCE ON COMPUTER SYSTEMS

     The Company's success will be dependent in part on the Company's ability to
coordinate and integrate the management and information systems ("MIS
systems") of the Founding Companies that are used for ordering products,
recording and analyzing financial results, controlling inventory and performing
other important functions. There can be no assurance that the Company will be
able to coordinate and integrate the MIS systems economically and it may
experience delays, disruptions and unanticipated expenses in doing so. Any such
event could have a material adverse effect on the Company's business, financial
condition and results of operations. The Company will not be able to fully
achieve certain contemplated operating efficiencies and competitive advantages
until it has fully coordinated and integrated the MIS systems. Until the Company
establishes coordinated and integrated MIS systems, which may not occur for
several years, it will rely primarily on the separate systems of the Founding
Companies. After the MIS systems are integrated, the Company will rely heavily
on them in its daily operations. Consequently, any interruption in the operation
of the MIS systems may have a material adverse effect on the Company's business,
financial condition and results of operations.

                                       11
<PAGE>
RELIANCE ON INDUSTRIES SUBJECT TO FLUCTUATING DEMAND

     Certain of the Company's products are sold to customers in industries that
experience significant fluctuations in demand based on economic conditions,
energy prices, consumer demand and other factors beyond the control of the
Company. No assurance can be given that the Company will be able to increase or
maintain its level of sales in periods of economic stagnation or downturn.

RELIANCE ON KEY PERSONNEL

     The Company will be highly dependent on the continuing efforts of its
executive officers and, due in part to the Company's decentralized operating
strategy, the senior management of the Founding Companies. In addition, the
Company is likely to depend on the senior management of any significant business
it acquires in the future. The Company's business, financial condition and
results of operations could be affected adversely if any of these persons do not
continue in his or her management role until the Company is able to attract and
retain qualified replacements. See "Management."

FLUCTUATIONS IN OPERATING RESULTS

     The Company's results of operations may fluctuate significantly from
quarter to quarter or year to year because of a number of factors, including the
timing of future acquisitions, fluctuations in the demand for its distribution
services and competitive factors. Accordingly, quarterly comparisons of the
Company's revenues and operating results should not be relied on as an
indication 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."

COMPETITION

     The Company is engaged in a highly fragmented and competitive industry.
Competition is based primarily on service, quality and geographic proximity. The
Company competes with a large number of fastener distributors on a regional and
local basis, some of which may have greater financial resources than the Company
and some of which are public companies or divisions of public companies. The
Company may also face competition for acquisition candidates from these
companies, some of whom have acquired fastener distribution businesses during
the past decade. Other smaller fastener distributors may also seek acquisitions
from time to time. See "Business -- Competition."

DEPENDENCE ON SUPPLIERS

     Certain types of specialized fasteners are available from only a limited
number of sources. If for any reason those sources became unavailable to the
Company, the Company would not be able to continue to sell such fasteners unless
an alternative supplier was located. The inability to supply certain types of
fasteners may adversely impact the Company's sales and its relationship with the
customers requiring such fasteners.

RISKS ASSOCIATED WITH GOVERNMENT REGULATION

     The Company's operations are subject to a number of federal, state and
local regulations relating to the protection of the environment and to workplace
health and safety. In addition, the Fastener Quality Act may impose additional
tracking, marking and testing requirements on the Company that could result in
operating costs that could adversely affect the Company's business, financial
condition and results of operations. See "Business -- Government Regulation."

CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS

     Following the consummation of the Acquisitions and the Offering, the
Company's executive officers and directors, former stockholders of the Founding
Companies and entities affiliated with them will beneficially own approximately
71.7% of the outstanding shares of Common Stock (68.8% if the Underwriters'
over-allotment option is exercised in full). These holders of Common Stock, if
acting in concert,

                                       12
<PAGE>
will be able to exercise control over the Company's affairs, to elect the entire
Board of Directors and to control the outcome of any matter submitted to a vote
of stockholders. See "Principal Stockholders."

SUBSTANTIAL PROCEEDS OF OFFERING PAYABLE TO AFFILIATES OF FOUNDING COMPANIES
   
     Of the net proceeds of the Offering, $28.7 million will be paid as the cash
portion of the purchase price for the Founding Companies. Certain of the
Founding Companies have incurred indebtedness which has been personally
guaranteed by their stockholders or by entities controlled by their
stockholders. Some of the recipients of these funds will become directors of the
Company or holders of more than 5% of the Common Stock. See "Principal
Stockholders." At September 30, 1997, the aggregate amount of indebtedness of
these Founding Companies was $29.4 million of which $19.5 million was subject to
personal guarantees. After September 30, 1997, the Founding Companies may borrow
up to an aggregate of $1.5 million to fund distributions to shareholders of the
Founding Companies that are S-corporations to enable certain shareholders to
make S-corporation income tax payments for 1997 and through the date of the
Acquisitions (the "S-Corporation Tax Payment Distributions"). No funds other
than the borrowed funds will be used to make the S-Corporation Tax Payment
Distributions. The Company intends to use the net proceeds from the Offering,
together with borrowings available from the Company's revolving credit facility,
to repay substantially all of the indebtedness of the Founding Companies.
Additionally, MGCV has agreed to advance to Pentacon, until the consummation of
the Acquisitions and the Offering, such funds as are necessary to effect the
Acquisitions and the Offering and will be reimbursed from the proceeds of the
Offering in respect of such expenses. As of September 30, 1997, MGCV had
advanced the Company $0.3 million for such expenses. See "Use of Proceeds" and
"Certain Transactions."
    
NO PRIOR PUBLIC MARKET AND DETERMINATION OF OFFERING PRICE

     Prior to the Offering, there has been no public market for the Common
Stock. Therefore, the initial public offering price for the Common Stock will be
determined by negotiation between the Company and the Representatives of the
Underwriters and may bear no relationship to the price at which the Common Stock
will trade after the Offering. See "Underwriting" for the factors to be
considered in determining the initial public offering price. The Company intends
to apply for listing of the Common Stock on the New York Stock Exchange.
However, there can be no assurance that an active trading market will develop
subsequent to the Offering or, if developed, that it will be sustained.

VOLATILITY OF MARKET PRICE

     After completion of the Offering, the market price of the Common Stock
could be subject to significant fluctuations due to variations in responses to
numerous factors, including the timing of any acquisitions by the Company,
variations in the Company's annual or quarterly financial results or those of
its competitors, changes by financial research analysts in their estimates of
the future earnings of the Company, conditions in the economy in general or in
the Company's industry in particular, unfavorable publicity or changes in
applicable laws and regulations (or judicial or administrative interpretations
thereof) affecting the Company or the fastener industry. In addition, the
securities markets have experienced significant price and volume fluctuations
from time to time in recent years. This volatility has had a significant effect
on the market prices of securities issued by many companies for reasons
unrelated to their operating performance, and these broad fluctuations may
adversely affect the market price of the Common Stock.

POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF COMMON STOCK

     Upon consummation of the Acquisitions and the Offering, 13,323,585 shares
of Common Stock will be outstanding. The 3,773,585 shares sold in the Offering
(other than shares that may be purchased by affiliates of the Company) will be
freely tradable. The remaining outstanding shares may be resold publicly only
following their registration under the Securities Act of 1933, as amended (the
"Securities Act"), or pursuant to an available exemption from registration
(such as provided by Rule 144 following a one year holding period for previously
unregistered shares). The holders of these remaining shares have agreed with the
Company that they will not sell, transfer or otherwise dispose of any of their
shares, for one year following the consummation of the Offering. Sales, or the
availability for sale, of substantial amounts of the

                                       13
<PAGE>
Common Stock in the public market could adversely affect prevailing market
prices and the future ability of the Company to raise equity capital and
complete any additional acquisitions for Common Stock. See "Shares Eligible for
Future Sale."

POSSIBLE ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS

     Pentacon's Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") authorizes the Board of Directors to issue,
without stockholder approval, one or more series of preferred stock having such
preferences, powers and relative, participating, optional and other rights
(including preferences over the Common Stock respecting dividends and
distributions and voting rights) as the Board of Directors may determine. The
issuance of this "blank-check" preferred stock could render more difficult or
discourage an attempt to obtain control of the Company by means of a tender
offer, merger, proxy contest or otherwise. In addition, the Certificate of
Incorporation provides for a classified Board of Directors, which may also have
the effect of inhibiting or delaying a change in control of the Company. Certain
provisions of the Delaware General Corporation Law may also discourage takeover
attempts that have not been approved by the Board of Directors. See
"Description of Capital Stock."

IMMEDIATE AND SUBSTANTIAL DILUTION

     Purchasers of Common Stock in the Offering will experience immediate and
substantial dilution in the net tangible book value of their stock of $      per
share, assuming an initial public offering price of $      , and may experience
further dilution in that value from issuances of Common Stock in connection with
future acquisitions. See "Dilution."

                                  THE COMPANY

     Pentacon was founded in March 1997 to become the leading domestic and
international value-added distributor of fasteners and other small parts to

                                USE OF PROCEEDS
   
     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby, after deducting estimated underwriting discounts and commissions
and estimated offering expenses payable by the Company, are estimated to be
approximately $43.1 million (approximately $50.0 million if the Underwriters
exercise their over-allotment option in full).

     Of the net proceeds, the Company estimates that approximately $28.7 million
will be used to pay the cash portion of the purchase price for the Founding
Companies, all of which will be paid to the stockholders of the Founding
Companies. The remainder of the purchase price for the Founding Companies will
be paid by the issuance of 6,720,000 shares of Common Stock to their
stockholders. In addition, approximately $14.4 million of the net proceeds will
be used to repay outstanding indebtedness of the Founding Companies at the
closing of the Offering. Of that $14.4 million, (i) approximately $5.5 million
is owed by Maumee to a financial institution, bears interest at 1.5% over the
bank's base rate or 10% at September 30, 1997 and matures May 31, 2000 and (ii)
approximately $6.5 million of the $9.5 million currently outstanding under a
line of credit provided to Alatec by a financial institution, bears interest at
the prime rate or 8.5% at September 30, 1997 and matures in June 1999. The
remaining indebtedness of $2.4 million to be repaid from the proceeds of the
Offering consists of various notes payable which bear interest ranging from 6.2%
to 9.3% and mature at various dates through January 2002. See "Certain
Transactions." After the consummation of the Offering and the Acquisitions and
after giving effect to the application of the proceeds as described above and to
the anticipated draw down on the Company's credit facilities, described below,
to pay off the Founding Companies' current indebtedness, the Company expects to
have a total of $9.1 million in debt outstanding.

     The Company has reached an agreement in principle with a bank for a credit
facility of $50 million. The bank has also agreed in principle to use its best
efforts to form a syndicate for an additional $25 million credit facility. The
Company intends to use such facilities for working capital, payoff of
indebtedness of the Founding Companies, and acquisitions. The credit facilities
will be subject to customary drawing conditions and the completion of
negotiations with the lender and the execution of appropriate loan
documentation.
    
                                DIVIDEND POLICY

     The Company intends to retain all its earnings, if any, to finance the
expansion of its business, and does not anticipate paying any cash dividends on
its Common Stock in the foreseeable future. Any future dividends will be at the
discretion of the Board of Directors after taking into account various factors,
including, among others, the Company's financial condition, results of
operations, cash flows from operations, current and anticipated cash needs and
expansion plans, the income tax laws then in effect and the requirements of
Delaware law. In addition, the credit facility may restrict or prohibit the
payment of dividends by the Company. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Results of
Operations -- Combined -- Combined Liquidity and Capital Resources."

                                    DILUTION

     The deficit in pro forma net tangible book value of the Company at
September 30, 1997 was approximately $8.7 million or $0.92 per share after
giving effect to the Acquisitions but before the Offering. Pro forma net
tangible book value per share is the adjusted tangible net worth (total tangible
assets less total liabilities) of the Company divided by the number of shares of
Common Stock outstanding after giving effect to the Acquisitions. Net tangible
book value dilution per share represents the difference between the amount per
share paid by purchasers of shares of Common Stock in the Offering and the pro
forma net tangible book value per share after the Offering. After giving effect
to the sale of the shares of Common Stock offered hereby (at an assumed price of
$     per share and after deducting underwriting discounts and commissions and
estimated offering expenses), the pro forma net tangible book value of the
Company at September 30, 1997 would have been $   million or      per share,
representing an immediate increase in net tangible book value of $3.50 per share
to existing stockholders and an immediate dilution of $     per share to the
investors purchasing the shares in the Offering ("New Investors"). The
following table illustrates this dilution to New Investors:

                            SELECTED FINANCIAL DATA
   
     Pentacon will acquire the Founding Companies simultaneously with and as a
condition to the consummation of the Offering. Pentacon has adopted a fiscal
year ended September 30. For financial statement presentation purposes, Alatec
has been identified as the "accounting acquiror." Effective January 1, 1997,
Alatec changed its fiscal year to September 30. The following selected
historical financial data for Alatec as of and for the years ended December 31,
1995 and 1996 and the nine month period ended September 30, 1997 have been
derived from audited financial statements of Alatec included elsewhere in this
Prospectus. The selected historical financial data as of, and for the years
ended December 31, 1993 and 1994, has been derived from unaudited financial
statements of Alatec, which have been prepared on the same basis as the audited
financial statements and, in the opinion of Alatec, reflect all adjustments
consisting of normal recurring adjustments, necessary for a fair presentation of
such data. The following summary unaudited pro forma combined financial data
presents certain data for the Company, adjusted for (i) the Acquisitions, (ii)
the effects of certain pro forma adjustments to the historical financial
statements and (iii) the consummation of the Offering and the application of the
net proceeds therefrom. See the Unaudited Pro Forma Combined Financial
Statements and the notes thereto included elsewhere in this Prospectus.

(1) The pro forma combined income statement data assumes that the Acquisitions
    and Offering were closed on January 1, 1997, (except for Capitol, whose
    historical results for nine months from December 1, 1996 to August 31, 1997
    were used for pro forma information), and are not necessarily indicative of
    the results the Company would have obtained had these events actually then
    occurred or of the Company's future results. During the periods presented
    above, the Founding Companies were not under common control or management
    and, therefore, the data presented may not be comparable to or indicative of
    post-combination results to be achieved by the Company. The pro forma
    combined income statement data are based on available information and
    certain assumptions that management deems appropriate and should be read in
    conjunction with the other financial statements and notes thereto included
    elsewhere in this Prospectus. Neither the potential cost savings from
    consolidating certain operational and administrative functions nor the costs
    of corporate overhead, other than salaries of executive officers, have been
    included in the pro forma combined financial information.

(2) The pro forma combined income statement data reflects an aggregate of
    approximately $2,146,000 in pro forma reductions in salary and benefits of
    the owners of the Founding Companies to which they have agreed
    prospectively, and $450,000 in pro forma increases in salary and benefits to
    the corporate management and $119,000 of expense reductions for the effect
    of revisions of certain lease agreements between certain stockholders of the
    Founding Companies and those Founding Companies. See "Certain
    Transactions."

(3) Reflects amortization of the goodwill for the nine month period to be
    recorded as a result of the Acquisitions over a 40-year period and computed
    on the basis described in the Notes to the Unaudited Pro Forma Combined
    Financial Statements.

(4) Includes interest income (expense) and other income (expense); net pro forma
    interest expense reflects a reduction in interest of $1,073,915 related to
    repayment of indebtedness with the proceeds from the Offering. See "Use of
    Proceeds."

(5) Consists of (i) 6,720,000 shares to be issued to the owners of the Founding
    Companies, (ii) 450,000 shares issued to the management of Pentacon, (iii)
    2,380,000 shares issued to MGCV, (iv) 3,773,585 shares to be sold in the
    Offering, (v) the dilutive effects of warrants to purchase 50,000 shares at
    an exercise price equal to the lesser of $8.00 or 60% of the initial public
    offering price per share using the treasury stock method and assuming an
    initial public offering price of $   per share. Subsequent to September 30,
    1997 (i) options to purchase 370,000 shares at the initial public offering
    price were issued and are currently outstanding and (ii) options to purchase
    600,000 shares at the initial public offering price are expected to be
    granted to the Company's employees upon consummation of the Offering.

(6) The pro forma combined balance sheet data assumes that the Acquisitions were
    closed on September 30, 1997. The pro forma combined balance sheet data is
    based upon available information and certain assumptions that management
    deems appropriate and should be read in conjunction with the other financial
    statements and notes thereto included elsewhere in this Prospectus.

(7) Reflects the closing of the Offering at an assumed price of $        per
    share and the Company's application of the net proceeds therefrom to fund
    the cash portion of the purchase price of the Acquisitions and to repay
    indebtedness of the Founding Companies. See "Use of Proceeds" and
    "Certain Transactions."

(8) Includes $28,662,387 for the obligation to pay the cash portion of the
    purchase price for the Founding Companies.

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

     The following discussion should be read in conjunction with the Founding
Companies' Financial Statements and related notes thereto and "Selected
Financial Data" appearing elsewhere in this Prospectus.

INTRODUCTION

     The Company's revenues are derived from the sale of fasteners and other
small parts with associated inventory management services. Net sales are
recognized upon shipment of the product to the customer.

     Cost of goods and services consists primarily of materials, cost of
products sold, costs for product processing and modification, freight and
obsolescence. Selling, general and administrative expenses consist primarily of
compensation and related benefits, advertising, facility rent and utilities,
communications and professional fees. Certain owners and certain key employees
of the Founding Companies have agreed to reductions totaling $2.1 million in
their compensation and related benefits in connection with their acquisition by
the Company on a pro forma basis for the nine months ended September 30, 1997.
Such reductions in salaries, bonuses and benefits are in accordance with the
terms of employment agreements. Certain facility leases have also been
renegotiated and the lessors have agreed to reductions totaling approximately
$119,000 on a pro forma basis for the nine months ended September 30, 1997. Both
adjustments have been reflected as a pro forma adjustment in the Unaudited Pro
Forma Combined Statement of Operations but have not been reflected in the
Historical Combined Statement of Operations.

     The Company anticipates that following the Acquisitions it will realize
savings from (i) greater volume discounts from suppliers, and (ii) consolidation
of insurance programs and other general and administrative expenses. However,
there will be costs related to the Company's new corporate management, costs
associated with being a public company and integration costs. None of these
savings or incremental costs are reflected in the Pro Forma or Historical
Combined Statement of Operations.

     Subsequent to September 30, 1997 the Company recorded a non-recurring
non-cash compensation charge of $4.7 million relating to certain shares of
Common Stock sold to management, based on the difference between an estimated
initial public offering price with a twenty percent marketability discount and
the amount paid for the shares. In addition, upon completion of the Offering, a
non-recurring non-cash charge of approximately $24.8 million based on an
estimated initial offering price to the public with a twenty percent
marketability discount will be recorded to reflect Offering expenses related to
the 2,380,000 shares of Common Stock held by MGCV. These charges will be offset
by increases in equal amounts in stockholders equity (par value common stock and
paid-in capital).

     As a result of the acquisition of the Founding Companies other than Alatec,
the excess of the fair value of the consideration paid over the fair value of
the net assets to be acquired will be recorded as goodwill on the Company's
balance sheet. Goodwill will be amortized as a non-cash charge to the income
statement over a 40-year period. Based on an initial public offering price of
$   per share, the initial amount of goodwill will be $43.3 million and the pro
forma impact of this amortization expense, which is non-deductible for tax
purposes, is expected to be approximately $1.1 million per year. Such
amortization expense is reflected in the Pro Forma Combined Results of
Operations but not the Historical Combined Results of Operations.

     The following sections present the results of the four largest Founding
Companies on an individual basis and on a combined basis for all Founding
Companies. The results of Capitol have not been presented separately as they do
not represent a significant portion of the combined Company's net sales. The
combined results do not include certain pro forma adjustments that the Company
expects to incur following the Acquisitions, including the reduction of salaries
among key employees of the Founding Companies and an increase in corporate
expenses. Pentacon has adopted a fiscal year ended September 30, and the
accounting acquiror, Alatec, has changed its fiscal year to September 30 to
conform to Pentacon's fiscal year end. The nine month period ended September 30,
1997, is therefore used for comparison purposes to the year ended December 31,
1996. Pentacon was founded in March 1997 and does not have financial statements
for the nine month period ended September 30, 1996. For the remaining Founding
Companies,

                                       22
<PAGE>
the nine month period ended September 30, 1997 is compared to the year ended
December 31, 1996. The comparison below between the nine months ended September
30, 1997 and prior period is made as follows: (i) for net sales, the comparison
is made versus the unaudited nine months ended September 30, 1996, and (ii) for
cost of goods sold, gross profit, selling, general and administrative expenses
and operating income, the comparison is made on a percentage of sales basis
between the nine months ended September 30, 1997 and the twelve months ended
December 31, 1996.

RESULTS OF OPERATIONS -- COMBINED

     The Combined Founding Companies Statements of Operations for the years
ended December 31, 1995 and 1996 and for the fiscal period comprised of the nine
months ended September 30, 1997 do not purport to present results of operations
of the combined Founding Companies in accordance with generally accepted
accounting principles, but are only a summation of the revenues, gross profit
and operating costs and expenses of the individual Founding Companies on a
historical basis and exclude the effects of pro forma adjustments. This data may
not be comparable to and may not be indicative of the Company's post combination
results of operations because (i) the Founding Companies were not under common
control or management during the periods presented; (ii) the Founding Companies
used different tax structures (S corporations and C corporations) during the
periods presented; (iii) the Company will incur incremental costs related to its
new corporate management and the costs of being a public company; (iv) the
Company will use the purchase method to record the Acquisitions, resulting in
the recording of goodwill that will be amortized over 40 years; and (v) the
combined data does not reflect the compensation differential and potential
benefits and costs savings the Company expects to realize when operating as a
combined entity.

     The following table sets forth the combined results of operations of the
Founding Companies on a historical basis and such results as a percentage of net
sales.

</TABLE>
  COMBINED NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO TWELVE MONTHS ENDED
     DECEMBER 31, 1996

     NET SALES.  Combined net sales increased $26.3 million, or 30.4%, from
$86.5 million for the nine months ended September 30, 1996 to $112.8 million for
the nine months ended September 30, 1997. The increase in combined net sales was
attributable to several factors, including net sales to new customers and an
increase in net sales to existing customers primarily at Alatec, AXS and Maumee
and an acquisition in the third quarter of 1996 by AXS. Net sales for Alatec
increased $9.0 million from the nine months ended September 30, 1996 to the nine
months ended September 30, 1997 due to an increase in net sales to new and
existing customers. Net sales for AXS increased $7.4 million from the nine
months ended September 30, 1996 to the nine months ended September 30, 1997 due
primarily to an acquisition during 1996 which accounted for $5.0 million of the
increase, three new customers which accounted for $0.8 million of the increase
and $1.0 million attributable to increased sales to new and existing customers
due to the customers' implementation of new inventory management systems. Net
sales for Maumee increased $8.3 million from the nine months ended September 30,
1996 to the nine months ended September 30, 1997 due to approximately a $4.5
million increase in sales to new customers and approximately a $5.5 million
increase with existing customers, offset by a $1.2 million reduction in net
sales to one existing customer. Net sales for the twelve months ended December
31, 1996 were $120.0 million compared to net sales for the nine months ended
September 30, 1997 of $112.8 million.

                                       23
<PAGE>
     COST OF SALES.  As a percentage of net sales, combined cost of sales
remained consistent at 65.8% in the twelve months ended December 31, 1996 and
65.9% in the nine months ended September 30, 1997.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  As a percentage of net
sales, selling, general and administrative expenses decreased from 26.1% in the
twelve months ended December 31, 1996 to 25.6% in the nine months ended
September 30, 1997. As a percentage of net sales, selling, general and
administrative expenses for Alatec decreased from 28.6% in the twelve months
ended December 31, 1996 to 27.7% in the nine months ended September 30, 1997 due
to an increase in net sales without a commensurate increase in administrative
costs. As a percentage of net sales, selling, general and administrative
expenses for AXS decreased from 24.1% in the twelve months ended December 31,
1996 to 22.7% in the nine months ended September 30, 1997. The decrease was
primarily due to reduced compensation expense related to personnel reductions
related to the elimination of duplicative positions resulting from the 1996
acquisition by AXS. As a percentage of net sales, selling, general and
administrative expenses for Maumee increased from 20.2% in the twelve months
ended December 31, 1996 to 24.0% in the nine months ended September 30, 1997.
The increase was primarily attributable to $1.2 million, or 4.4%, as a
percentage of net sales, in costs associated with the issuance of stock to a key
employee.

     OPERATING INCOME.  As a percentage of net sales, combined operating income
increased from 8.1% in the twelve months ended December 31, 1996 to 8.5% in the
nine months ended September 30, 1997 due to the factors discussed above.

  COMBINED YEAR ENDED 1996 COMPARED TO YEAR ENDED 1995

     NET SALES.  Combined net sales increased $15.9 million, or 15.3%, from
$104.1 million in 1995 to $120.0 million in 1996. Net sales for Alatec increased
$3.5 million from 1995 to 1996 due to an increase in net sales to existing
customers. Net sales for AXS increased $3.0 million from 1995 to 1996 due to an
acquisition in 1996 which accounted for $2.7 million of the increase. Net sales
for Maumee increased $5.6 million from 1995 to 1996 due to an increase in net
sales to new and existing customers. Net sales for SSL increased $3.5 million
primarily due to an increase of approximately $2.2 million in net sales to an
existing customer.

     COST OF SALES.  Combined cost of sales increased $8.7 million, or 12.4%,
from $70.3 million in 1995 to $79.0 million in 1996. The increase in combined
cost of sales was primarily a result of the increase in net sales for 1996 and
increased costs related to AXS' 1996 acquisition. As a percentage of net sales,
combined cost of sales decreased from 67.5% in 1995 to 65.8% in 1996 primarily
due to an increase in sales of products with higher margins.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Combined selling, general
and administrative expenses increased $4.3 million, or 15.9%, from $27.0 million
in 1995 to $31.3 million in 1996. The increase in combined selling, general and
administrative expenses was primarily due to several factors including an
increase in personnel to support a higher volume of business and increased costs
related to AXS' 1996 acquisition. As a percentage of net sales, combined
selling, general and administrative expenses increased from 26.0% in 1995 to
26.1% in 1996.

     OPERATING INCOME.  Due to the factors discussed above, combined operating
income increased $2.9 million, or 42.6%, from $6.8 million in 1995 to $9.7
million in 1996. As a percentage of net sales, operating income increased from
6.5% in 1995 to 8.1% in 1996.

  COMBINED LIQUIDITY AND CAPITAL RESOURCES

     On a combined basis the Founding Companies generated $2.1 million of net
cash from operating activities for the nine months ended September 30, 1997,
which was used primarily for working capital requirements. Net cash used in
investing activities was $0.6 million on a combined basis for the nine months
ended September 30, 1997, primarily for capital expenditures. Net cash used in
financing activities was $1.9 million for the nine months ended September 30,
1997 and primarily consisted of distributions to stockholders of $1.2 million
and reductions in borrowings under lines of credit of $1.6 million. At

                                       24
<PAGE>
September 30, 1997, the combined Founding Companies had cash of $3.6 million,
working capital of $26.0 million and total debt of $29.4 million (including $7.0
million of debt to related parties).

     On a combined basis, the Founding Companies generated $2.2 million of net
cash from operating activities during 1996 primarily for working capital
requirements. Net cash used in investing activities was $0.3 million on a
combined basis for 1996 and was used primarily for capital expenditures. Net
cash used in financing activities was $0.4 million on a combined basis and
primarily consisted of advances under lines of credit of $1.8 million offset by
distributions to stockholders of $1.2 million. At December 31, 1996, the
combined Founding Companies had cash of $3.9 million, working capital of $23.9
million and total debt of $25.3 million, including $2.5 million of debt to
related parties.

     The Company intends to obtain a credit facility which would be available
upon the closing of the Offering. This credit facility would provide for a
revolving line of credit up to $45 million, which would be used for general
corporate purposes, including post-offering acquisitions, capital expenditures,
and working capital. The ability of the Company to secure the credit facility is
subject to satisfactory negotiations with prospective lenders as well as the
execution of loan documentation. Upon the completion of the Offering, the
Company intends to borrow approximately $5.1 million to repay certain assumed
indebtedness of the Founding Companies.

     The Company intends to actively pursue acquisition opportunities. The
Company expects to fund acquisitions through the issuance of additional Common
Stock, borrowings (including use of amounts available under its credit
facility), and cash flow from operations. The Company has agreed to repay
substantially all of the Founding Companies' outstanding bank loans. Such
payments will include $150,000 in prepayment penalties. Capital expenditures for
equipment and expansion of facilities are expected to be funded from cash flow
from operations and supplemented as necessary by borrowings from the credit
facility or other sources of financing. The Company anticipates that its cash
flow from operations will be sufficient to meet the Company's normal working
capital and debt service requirements for at least the next several years.
   
     The Company anticipates spending approximately $2.5 million on updating and
combining the Founding Companies' computer systems. Such costs include the
estimated cost of any software updates required to allow the systems to process
data attributable to the year 2000 and thereafter. The funds to pay such costs
will be obtained from cash flow, the Company's credit facilities, or both.

     NET SALES.  Net sales increased $9.0 million, or 27.0%, from $33.3 million
for the nine months ended September 30, 1996 to $42.3 million for the nine
months ended September 30, 1997. Approximately $1.0

                                       25
<PAGE>
million of this increase was attributable to new customers and approximately
$8.0 million was due to an increase in net sales to existing customers. Net
sales for the twelve months ended December 31, 1996 were $44.7 million compared
to net sales for the nine months ended September 30, 1997 of $42.3 million.

     COST OF SALES.  As a percentage of net sales, cost of sales remained
relatively constant at 59.3% in the nine months ended September 30, 1997
compared to 59.7% the twelve months ended December 31, 1996.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  As a percentage of net
sales, selling, general and administrative expenses decreased from 28.6% in the
twelve months ended December 31, 1996 to 27.7% in the nine months ended
September 30, 1997. This percentage decrease was a result of the increase in net
sales without a commensurate increase in administrative costs.

     OPERATING INCOME.  As a percentage of net sales, operating income increased
from 11.7% in the twelve months ended December 31, 1996 to 13.0% in the nine
months ended September 30, 1997 as a result of the factors discussed above.

  ALATEC YEAR ENDED 1996 COMPARED TO YEAR ENDED 1995

     NET SALES.  Net sales increased $3.5 million, or 8.5%, from $41.2 million
in 1995 to $44.7 million in 1996. Approximately $1.0 million of this increase
was attributable to new customers and approximately $2.5 million was due to an
increase in net sales to existing customers.

     COST OF SALES.  Cost of sales increased $0.5 million, or 1.9%, from $26.2
million in 1995 to $26.7 million in 1996. As a percentage of net sales, cost of
sales decreased from 63.6% in 1995 to 59.7% in 1996. The decrease was primarily
due to an increase in sales of products with higher margins.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $1.5 million, or 13.3%, from $11.3 million in
1995 to $12.8 million in 1996. Approximately $0.6 million of this increase was
due to the hiring of additional personnel to support certain new just in time
supply contracts and the majority of the remainder was related to wage increases
and overtime expense. As a percentage of net sales, selling, general and
administrative expenses increased from 27.4% in 1995 to 28.6% in 1996.

     OPERATING INCOME.  Due to the factors discussed above, operating income
increased $1.5 million, or 40.5%, from $3.7 million in 1995 to $5.2 million in
1996. As a percentage of net sales, operating income increased from 9.0% in 1995
to 11.7% in 1996.

  ALATEC LIQUIDITY AND CAPITAL RESOURCES

     At September 30, 1997, Alatec had working capital of $20.2 million,
compared to working capital of $17.1 million at December 31, 1996. Alatec's
principal capital requirements have been to fund inventory and accounts
receivable and purchase and upgrade property and equipment. Historically, these
requirements have been met by cash flows from operating activities and
borrowings under bank lines of credit.

     Net cash provided by (used in) operating activities for the years ended
December 31, 1995 and 1996 and the nine months ended September 30, 1997 was
$(1.1) million, $(0.4) million and $0.1 million, respectively. Net cash used in
investing activities for the years ended December 31, 1995 and 1996 and the nine
months ended September 30, 1997 was $0.1 million, $0.3 million and $0.1 million,
respectively. The net cash used for investing activities during these periods
was primarily attributable to capital expenditures of which the individual
components of these expenditures were not significant.
   
     Net cash provided by financing activities for the years ended December 31,
1995 and 1996 and the nine months ended September 30, 1997 was $1.0, $0.9
million and $0.5 million, respectively.
    
     As of September 30, 1997, Alatec had a $13.3 million bank credit facility
secured by accounts receivable, inventories, equipment and the guarantee of the
principal stockholder. The facility will expire in June 1999. At September 30,
1997, approximately $3.0 million was available for borrowings. The credit
agreement contains certain restrictive financial covenants including, but not
limited to, minimum working capital requirements and dividend restrictions. As
of September 30, 1997, the Company was in compliance with the financial
covenants. However, at September 30, 1997 Alatec was not in compliance with
certain

                                       26
<PAGE>
nonfinancial covenants relating to providing information and notice of defined
transactions and events to the bank. The bank has provided a written waiver for
these covenant violations and management believes that the Company will be in
compliance with these covenants in future periods. It is anticipated that the
bank credit facility will be repaid upon consummation of the Offering.

  AXS NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO THE TWELVE MONTHS ENDED
DECEMBER 31, 1996

     NET SALES.  Net sales increased $7.4 million, or 50.7% from $14.6 million
for the nine months ended September 30, 1996 to $22.0 million for the nine
months ended September 30, 1997. The increase was due to the acquisition of Hoyt
during the third quarter of 1996, which accounted for $5.0 million of the
increase, three new customers which accounted for $0.8 million of the increase
and $1.0 million attributable to increased sales to new and existing customers
due to the customers' implementation of inventory management systems. Net sales
for the twelve months ended December 31, 1996 were $23.2 million compared to net
sales for the nine months ended September 30, 1997 of $22.0 million.
   
     COST OF SALES.  As a percentage of net sales, cost of sales increased from
65.1% in the twelve months ended December 31, 1996 to 69.6% in the nine months
ended September 30, 1997. The increase was primarily due to the writedown of
slow-moving inventory to market of approximately $700,000. The inventory written
down to market was not concentrated in any particular class or classes of
inventory and resulted from more inventory meeting the Company's slow-moving or
obsolescence criteria in a variety of classes of inventory.
    
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  As a percentage of net
sales, selling, general and administrative expenses decreased from 24.1% in the
twelve months ended December 31, 1996 to 22.7% in the nine months ended
September 30, 1997. The decrease was primarily due to reduced compensation
expense related to the termination of an executive level position and other
personnel reductions related to the elimination of duplicative positions
resulting from the 1996 acquisition of Hoyt.

     OPERATING INCOME.  As a percentage of net sales, operating income decreased
from 10.8% in the twelve months ended December 31, 1996 to 7.7% in the nine
months ended September 30, 1997.

  AXS YEAR ENDED 1996 COMPARED TO YEAR ENDED 1995

     NET SALES.  Net sales increased $3.0 million, or 14.9%, from $20.2 million
in 1995 to $23.2 million in 1996. The increase was primarily due to the
acquisition of Hoyt during the third quarter of 1996, which accounted for $2.7
million of the increase.

                                       27
<PAGE>
     COST OF SALES.  Cost of sales increased $2.1 million, or 16.2%, from $13.0
million in 1995 to $15.1 million in 1996. The increase was primarily
attributable to the increase in net sales in 1996 and costs associated with the
1996 acquisition of Hoyt. As a percentage of net sales, cost of sales increased
from 64.4% in 1995 to 65.1% in 1996. The increase was primarily due to an
increase in the sale of products with lower profit margins.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $0.9 million, or 19.1%, from $4.7 million in
1995 to $5.6 million in 1996. Substantially all of this increase was related to
costs associated with the 1996 acquisition of Hoyt. As a percentage of net
sales, selling, general and administrative expenses increased from 23.3% in 1995
to 24.1% in 1996.

     OPERATING INCOME.  Due to the factors discussed above, operating income
remained constant at $2.5 million for both periods. As a percentage of net
sales, operating income decreased from 12.3% in 1995 to 10.8% in 1996.

  AXS LIQUIDITY AND CAPITAL RESOURCES

     At September 30, 1997, AXS' working capital was $4.3 million, compared to
working capital of $6.4 million at December 31, 1996. AXS' principal capital
requirements have been to fund inventory and purchase and upgrade property and
equipment. Historically, these requirements have been met by cash flows from
operating activities and borrowings under bank lines of credit.

     Net cash provided by operating activities for the years ended December 31,
1995 and 1996 and the nine months ended September 30, 1997 was $3.4 million,
$2.5 million and $1.9 million, respectively. Net cash provided by (used in)
investing activities for the years ended December 31, 1995 and 1996 and the nine
months ended September 30, 1997 was $(0.2) million, $0.3 million and $(0.1)
million, respectively. The net cash used in investing activities during these
periods was primarily attributable to capital expenditures of which the
individual components of these expenditures were not significant.

     Net cash used in financing activities for the years ended December 31, 1995
and 1996 and the nine months ended September 30, 1997 was $2.5 million, $0.9
million and $2.5 million, respectively.
   
     The Company continuously evaluates its inventory for slow-moving and
obsolete inventory and makes appropriate non-cash charges to cost of sales to
write any such inventory down to market. During the nine months ended September
30, 1997, the Company wrote down inventory by approximately $0.7 million as a
result of an increase of items which met the Company's slow-moving or obsolete
inventory criteria as compared to no write-down during the year ended December
31, 1996. The write-down was due to the accumulation of prior purchases in a
variety of inventory classes for which sales have slowed down or ceased. The
inventory that became slow-moving or obsolete in 1997 was not due to the loss of
any significant customer, and management does not believe the write-down in 1997
was the result of a continuing trend. Management is monitoring its purchasing
patterns to better reflect demand and does not expect this trend to continue.
    
     As of September 30, 1997, AXS had a $3.0 million bank credit facility
secured by separate balances with the bank and the guarantee of the two
principal stockholders, which was due on demand. At September 30, 1997
approximately $1.1 million was available for borrowings. It is anticipated that
the bank credit facility will be repaid upon consummation of the Offering.

for the nine months ended September 30, 1996 to $27.5 million for the nine
months ended September 30, 1997. Approximately $4.0 million of this increase was
attributable to new customers and approximately $5.5 million was due to an
increase in net sales to existing customers offset by approximately a $1.2
million reduction in net sales to one existing customer. Net sales for the
twelve months ended December 31, 1996 were $26.2 million compared to net sales
for the nine months ended September 30, 1997 of $27.5 million.

     COST OF SALES.  As a percentage of net sales, cost of sales decreased from
75.2% in the twelve months ended December 31, 1996 to 71.3% in the nine months
ended September 30, 1997. The decrease was due to a higher margin product mix
from new products and from the use of lower cost suppliers.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  As a percentage of net
sales, selling, general, and administrative expenses increased from 20.2% in the
twelve months ended December 31, 1996 to 24.0% in the nine months ended
September 30,1997. The increase was primarily attributable to $1.2 million, or
4.4%, as a percentage of net sales, in costs associated with the issuance of
stock to a key employee.

     OPERATING INCOME.  As a percentage of net sales, operating income increased
from 4.6% in the twelve months ended December 31, 1996 to 4.7% in the nine
months ended September 30, 1997.

  MAUMEE YEAR ENDED 1996 COMPARED TO YEAR ENDED 1995

     NET SALES.  Net sales increased $5.6 million, or 27.2%, from $20.6 million
in 1995 to $26.2 million in 1996. Approximately $1.0 million of this increase
was attributable to a new customer and the majority of the remainder was
attributable to an increase in net sales to existing customers.

     COST OF SALES.  Cost of sales increased $3.6 million, or 22.4%, from $16.1
million in 1995 to $19.7 million in 1996, primarily as a result of the increase
in sales in 1996. As a percentage of net sales, cost of sales decreased from
78.2% in 1995 to 75.2% in 1996. The decrease was due to increased sales of
higher margin products.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $0.7 million, or 15.2%, from $4.6 million in
1995 to $5.3 million in 1996. This increase was primarily due to an increase in
personnel needed to support increased sales volume. As a percentage of net
sales, selling, general and administrative expenses decreased from 22.3% in 1995
to 20.2% in 1996.

     OPERATING INCOME.  Operating income increased $1.3 million from $(0.1)
million in 1995 to $1.2 million in 1996. As a percentage of net sales, operating
income increased from a loss in 1995 to 4.6% in 1996.

  MAUMEE LIQUIDITY AND CAPITAL RESOURCES

     At September 30, 1997, Maumee had a working capital deficit of $1.9
million, compared to a working capital deficit of $3.0 million at December 31,
1996. Maumee's principal capital requirements have been to

                                       29
<PAGE>
fund inventory and accounts receivable and purchase and upgrade property and
equipment to support the growth of the Company. Historically, these requirements
have been met by cash flows from operating activities and borrowings under bank
lines of credit.
   
     Net cash used in operating activities for the years ended December 31, 1995
and 1996 and the nine months ended September 30, 1997 was $0.6 million, $0.03
million and $0.6 million, respectively. The usage of cash from operations during
these three periods is due to the working capital requirements to fund the
growth and successful turnaround of the Company. During the three periods
presented the Company has been focused on increasing sales volume and returning
the Company to profitability. As noted above, sales have increased 27.2% from
1995 to 1996 and increased 43.2% for the nine months ended September 30, 1996 to
the nine months ended September 30, 1997. The usage of cash from operations has
primarily been to support the increase in inventory and accounts receivable
offset by an increase in accounts payable related to the increase in sales
volume. As sales volumes have increased, the Company's gross margins have
increased as a result of the Company's ability to decrease its costs to purchase
certain inventory and to focus on selling higher margin products. Management has
decreased its working capital deficit by $0.9 million during the nine months
ended September 30, 1997 and anticipates the Company's historical gross margin
will remain stable and result in the Company's ability to generate cash flows
from operations and generate working capital.
    
     Net cash used in investing activities for the years ended December 31, 1995
and 1996 and the nine months ended September 30, 1997 was $0.2 million, $0.1
million and $0.2 million, respectively. The net cash used for investing
activities during these periods was primarily attributable to capital
expenditures of which the individual components of these expenditures were not
significant.

     Net cash provided by financing activities for the years ended December 31,
1995 and 1996 and the nine months ended September 30, 1997 was $0.8 million,
$0.2 million and $0.7 million, respectively.
   
     As of September 30, 1997, Maumee had a $7.7 million bank credit facility
secured by substantially all of Maumee's assets including accounts receivable,
inventories, equipment and the guarantee of the principal stockholder. The
facility will expire May 31, 2000. At September 30, 1997, approximately $2.2
million was available for borrowings. It is anticipated that the bank credit
facility will be repaid upon consummation of the Offering.

                                       30
<PAGE>
relatively constant for both periods primarily due to a reduction of
approximately $2.0 million in net sales to one existing customer offset by an
increase in net sales of approximately $2.0 million to other customers. Net
sales for the twelve months ended December 31, 1996 were $15.7 million compared
to net sales for the nine months ended September 30, 1997 of $12.0 million.

     COST OF SALES.  As a percentage of net sales, cost of sales increased from
66.9% in the twelve months ended December 31, 1996 to 67.5% in the nine months
ended September 30, 1997 due to increased supplier costs.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  As a percentage of net
sales, selling, general and administrative expenses decreased from 29.3% in the
twelve months ended December 31, 1996 to 25.8% in the nine months ended
September 30, 1997. The decrease was attributable to a reduction in personnel
and related expenses.

     OPERATING INCOME.  As a percentage of net sales, operating income increased
from 3.8% in the twelve months ended December 31, 1996 to 6.7% in the nine
months ended September 30, 1997, due to the factors discussed above.

  SSL YEAR ENDED 1996 COMPARED TO YEAR ENDED 1995

     NET SALES.  Net sales increased $3.5 million, or 28.7%, from $12.2 million
in 1995 to $15.7 million in 1996. Approximately $2.2 million of this increase
was attributable to one customer and the remainder of the increase was due to
increased net sales to other customers.

     COST OF SALES.  Cost of sales increased $2.5 million, or 31.3%, from $8.0
million in 1995 to $10.5 million in 1996, primarily as a result of the increase
in sales in 1996. As a percentage of net sales, cost of sales increased from
65.6% in 1995 to 66.9% in 1996. The increase was due to competitive pricing and
lower margins on the increased net sales related to the one customer mentioned
above.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $0.9 million, or 24.3%, from $3.7 million in
1995 to $4.6 million in 1996. The increase was due in part to the higher volume
of business, but also reflects the addition of personnel to support the
additional net sales related to the one existing customer mentioned above. As a
percentage of net sales, however, selling, general and administrative expenses
decreased from 30.3% in 1995 to 29.3% in 1996.

     OPERATING INCOME.  Operating income increased $0.1 million, or 20.0%, from
$0.5 million in 1995 to $0.6 million in 1996. As a percentage of net sales,
operating income decreased from 4.1% in 1995 to 3.8% in 1996, due to the factors
discussed above.

  SSL LIQUIDITY AND CAPITAL RESOURCES

     At September 30, 1997, SSL had working capital of $1.9 million, compared to
working capital of $1.4 million at December 31, 1996. SSL's principal capital
requirements have been to fund inventory and accounts receivable and purchase
and upgrade property and equipment. Historically, these requirements have been
met by cash flows from operating activities and borrowings under bank lines of
credit.

     Net cash provided by (used in) operating activities for the fiscal year
ended December 31, 1996 and the nine months ended September 30, 1997 was $(0.1)
million and $1.2 million, respectively. Net cash used in investing activities
for the fiscal year ended December 31, 1996 and the nine months ended September
30, 1997 was $0.2 million and $0.1 million, respectively. The net cash used for
investing activities during these periods was primarily attributable to capital
expenditures of which the individual components of these expenditures were not
significant.

     Net cash provided by (used in) financing activities for the fiscal year
ended December 31, 1996 and the nine months ended September 30, 1997 was $0.3
million and $(1.2) million, respectively. SSL paid distributions to shareholders
of $0.2 million in 1996 and 1997. Borrowings in 1996 were primarily made to fund
working capital requirements. During 1997 SSL repaid a portion of the borrowings
under its revolving bank credit facility. Prior to the Acquisitions, SSL
anticipates borrowing approximately $0.5 million to fund its portion of the S
Corporation Tax Payment Distributions.

     As of September 30, 1997, SSL had a $1.3 million bank credit facility
secured by accounts receivable and inventories and the guarantee of the
stockholders which will expire on June 1, 1998. At September 30, 1997,
approximately $0.9 million was available for borrowings. It is anticipated that
the bank credit facility will be repaid upon consummation of the Offering.

SEASONALITY AND QUARTERLY FLUCTUATIONS

     The Company experiences modest seasonal declines in the fourth calendar
quarter due to declines in its customers' activities in that quarter. The
Company's volume of business may be adversely affected by a decline in projects
as a result of regional or national downturns in economic conditions. Quarterly
results may also be materially affected by the timing of acquisitions and the
timing and magnitude of acquisition assimilation costs. Accordingly, the
operating results for any three-month period are not necessarily indicative of
the results that may be achieved for any subsequent fiscal quarter or for a full
fiscal year.

INFLATION

     Inflation has not had a material impact on the Company's results of
operations for the last three years.

                                    BUSINESS

GENERAL

     The Company is a leading distributor of fasteners and other small parts and
provider of related inventory procurement and management services to original
equipment manufacturers ("OEMs") on a worldwide basis. Fasteners and small
parts include screws, bolts, nuts, washers, pins, rings, fittings, springs,
electrical connectors and similar parts. Pentacon was founded in March 1997 to
aggressively pursue the consolidation of the highly-fragmented fastener
distribution industry. According to an industry study by The Freedonia Group,
Inc., sales by fastener manufacturers in 1996 were approximately $8.0 billion in
the United States and $25.0 billion globally. The United States fastener market
is estimated to have over 1,900 distributors. The Company believes that the OEM
fastener and small part distribution industry is in the early stages of
consolidation, and the Company plans to lead the consolidation of the industry.
The Company believes that its broad selection of fasteners and small parts, high
quality services, professional management team, and strong competitive position
as a publicly-owned fastener distributor focused on the OEM market, will allow
it to be the leading consolidator.

     Fasteners and other small parts constitute a majority of the total number
of parts needed by an OEM to manufacture many products, but represent only a
small fraction of the total materials cost. The cost for an OEM to internally
manage its inventory of fasteners and small parts is relatively high due to (i)
the large number of fasteners and other small parts in the inventory, (ii) the
risk of interruptions for just-in-time ("JIT") manufacturing operations, and
(iii) the need to perform quality assurance testing of the fasteners and small
parts. The Company believes that OEMs are increasingly outsourcing their
fastener and other small parts inventory procurement and management needs to
distributors in order to focus on their core manufacturing businesses and to
reduce costs. To further reduce costs, many manufacturers are seeking to
consolidate the number of distributors they use and are selecting national
distributors with extensive product lines who can also provide inventory-related
services. To capitalize on these trends, the Company offers a broad array of
fasteners and small parts and provides a variety of related procurement and
inventory management services, including inventory management information
systems ("MIS") and reports, JIT delivery, quality assurance, advisory
engineering services, component kit production and delivery, small component
assembly and electronic data interchange ("EDI").
   
     Upon consummation of the Offering, Pentacon will acquire the five Founding
Companies, which have been in business an average of 25 years and which had
combined net sales of $120.0 million in 1996 and $112.8 million for the nine
months ended September 30, 1997. While total U.S. sales of fasteners have
increased at a compound annual rate of approximately 4.1% during the four years
ending December 31, 1996, the combined net sales of the Founding Companies have
increased at a compound annual rate of approximately 14.8% per year over the
same period. The Company believes that it has generated superior growth
primarily by expanding the breadth of its product offerings and value-added
services, which has allowed the Founding Companies to increase market share at
existing customers and attract new customers.
    
INDUSTRY OVERVIEW

     Companies operating in the fastener distribution business can generally be
characterized by the end users they serve, which are comprised broadly of OEMs,
maintenance and repair operations ("MROs") and construction companies. The
traditional fastener distribution market is similar to most industrial
distribution markets. Fasteners are purchased from both domestic and overseas
manufacturers and sold to both domestic and overseas customers. The majority of
these fasteners are sold to OEM and MRO clients on a purchase order basis. Some
smaller distributors specialize along industry lines because of the uniqueness
of manufacturer requirements. Other smaller distributors provide a wide range of
fasteners used for general assembly. Larger distributors, such as the Company,
generally provide a wide range of fasteners as well as meet certain specialized
industry needs.

     The U.S. sales by fastener manufacturers was estimated to be approximately
$8.0 billion in 1996, and the global market for fasteners is estimated to be
$25.0 billion. The OEM market represents in excess of 80% of the total U.S.
fastener market, the MRO market accounts for 13% with construction and other

                                       33
<PAGE>
   
markets accounting for the remaining 7%. There are in excess of 1,900 fastener
distributors in the United States, none of which is responsible for more than 4%
of the market sales. The Company believes that there is currently only one
public company whose primary business is fastener distribution. The industry
data provided herein were derived from several sources including Dun &
Bradstreet and The Freedonia Group, Inc. The following table lists the
approximate number of privately owned fastener companies in the U.S. by size:

     Customer demand for inventory management services and electronic data
exchange has required industry participants to make substantial investments in
sophisticated computer systems in order to remain competitive. Automated
inventory picking, component kit assembly and quality control laboratories also
require significant capital investment in equipment. In addition, many customers
are seeking to reduce their operating costs by decreasing the number of
suppliers with whom they do business, often eliminating those suppliers offering
limited ranges of products and services. The Company believes that these trends
have placed a substantial number of small, owner-operated fastener distributors
at a competitive disadvantage because of their limited product lines and
inventory systems. In addition they have limited access to the capital resources
necessary to modernize and expand their capabilities. The owners of these
businesses traditionally have not had a viable exit strategy, leaving them with
few attractive liquidity options. Due in part to these factors, the Company
believes that the opportunity exists for a well capitalized professionally
managed company to lead the consolidation of the industry.
    
BUSINESS STRATEGY

     The Company intends to become the leading fastener and small parts
distributor on a worldwide basis. Key elements of the Company's strategy to
achieve its objective are:

          PROVIDE VALUE-ADDED SERVICES.  The Company seeks to continually
     develop and supply inventory-related services designed to reduce its
     customers' operating costs. Quality assurance, JIT delivery and component
     kit production are examples of such services currently provided by the
     Company to its customers. By supplying such services, the Company becomes
     more integrated into the customers' internal manufacturing processes and is
     better able to anticipate its customers' needs which the Company believes
     results in improved profitability and customer retention.

          DELIVER SUPERIOR CUSTOMER SERVICE.  OEMs and other fastener customers
     choose fastener suppliers based, in significant part, on the quality of the
     service supplied. The Company believes that its superior customer service
     depends on its well-trained, technically competent workforce and that its
     workforce provides an advantage over other fastener distributors. The
     Company intends to review the training and operating practices at each
     Founding Company to identify and adopt those "best practices" in
     providing customer service that can be successfully implemented throughout
     its operations. As part of its commitment to superior customer service, the
     Company intends to have each of its operating companies certified under the
     International Standards Organization ("ISO") standards for distribution
     companies.

                                       34
<PAGE>
          ACCELERATE INTERNAL SALES GROWTH.  One of the primary goals of the
     Company is to accelerate internal growth by both expanding the range of
     products and services provided to existing customers and aggressively
     pursuing new customers domestically and abroad. The Company believes it
     will be able to expand sales to existing customers by capitalizing on (i)
     the diverse products and the marketing expertise of the Founding Companies,
     (ii) cross-selling opportunities across the Company's customer base, and
     (iii) the additional financial resources that are expected to be available
     after consummation of the Offering. The Company believes its broad
     geographic coverage will present opportunities to capture additional
     business from existing customers that operate on a national and
     international basis. The Company intends to implement a company-wide
     marketing program and to adopt the "best practices" used by the Founding
     Companies to identify, obtain and maintain new customers.

          EXPAND OPERATING MARGINS.  The Company believes that the combination
     of the Founding Companies will provide significant opportunities to
     increase its profitability. The key components of this strategy are to
     increase operating efficiencies and centralize appropriate administrative
     functions. The Company intends to use its increased purchasing power to
     improve contractual relationships and gain volume discounts from its
     suppliers. The Company also intends to improve productivity through
     enhanced inventory management procedures, increased utilization of the
     Company's laboratories and distribution facilities, and the consolidation
     of information systems and employee benefits.

          AGGRESSIVELY PURSUE ACQUISITIONS.  The Company believes that the
     fastener distribution industry is highly fragmented and in the early stages
     of consolidation. The Company intends to pursue an aggressive acquisition
     program targeting fastener distributors that will help the Company increase
     its presence in markets it currently services, sell to new markets, develop
     new customer relationships with major OEMs, increase its presence in the
     international markets and expand its range of products and services. The
     Company believes there is a significant number of acquisition candidates
     available and that it will be regarded as an attractive acquiror due to its
     position as an industry leader, its ability to offer cash and/or
     publicly-traded stock for acquisitions, and the potential for improved
     growth and profitability as part of the Company.

ACQUISITION STRATEGY

     The Company intends to pursue an aggressive acquisition program. The
Company intends to acquire other fastener distributors in order to enter new
industries and markets; increase sales in certain industries it currently
serves; develop new customer relationships with major OEMs; expand the
geographical reach of the Company; and expand its range of products and
services. Potential acquisition candidates will be evaluated on the strength of
management, quality of customer service, profitability and industry orientation.

     The Company believes it will be regarded by acquisition candidates as an
attractive acquiror because of (i) the Company's strategy for creating an
international, comprehensive and professionally managed value-added distributor
of fasteners and other small parts to OEMs; (ii) the Company's ability to
acquire businesses with a combination of cash and publicly traded stock; (iii)
the Company's increased visibility and access to financial resources as a public
company; and (iv) the potential for increased profitability of the acquired
company due to purchasing economies, centralization of administrative functions,
enhanced systems capabilities and access to increased marketing resources.
   
     The Company believes management of the Founding Companies will be
instrumental in identifying and completing future acquisitions. Moreover,
several of the principals of the Founding Companies have held leadership roles
in industry trade associations, which have enabled these individuals to develop
relationships with the owners of numerous acquisition targets across the
country. The Company expects that the visibility of these individuals and the
Company within the industry will increase the awareness of, and interest of
acquisition candidates in, the Company and its acquisition program. Within the
past several months, the Company has contacted the owners of a number of
acquisition candidates, several of whom have expressed interest in discussing
the sale of their businesses to the Company. The Company has engaged in
preliminary discussions with a few potential acquisition candidates; however,
the Company has not engaged in any material negotiations with such candidates,
and the Company does not have any

agreements, understandings, arrangements or commitments with respect to any
acquisitions other than the acquisitions of the Founding Companies.
    
     As consideration for future acquisitions, the Company intends to primarily
use various combinations of its Common Stock and cash. The consideration for
each future acquisition will vary on a case-by-case basis, with the major
factors in establishing the purchase price being historical operating results,
future prospects of the target and the ability of the target to provide entry to
new OEM markets or customers. Within 90 days following the completion of the
Offering, the Company intends to register 3,350,000 additional shares of Common
Stock under the Securities Act for its use in connection with future
acquisitions. The Company believes that it can structure certain acquisitions as
tax-free reorganizations by using its Common Stock as consideration, which will
be attractive to those targeted business owners with a low-tax basis in the
stock of their businesses. See "Risk Factors -- Risks Related to the Company's
Acquisition Strategy."

PRODUCTS

     The Company distributes over 100,000 different fasteners and other small
parts, generally denoted by a unique standard identifier known as a Stockkeeping
Unit ("SKU"). The SKUs fall into two general categories: fasteners and other
small parts.

     FASTENERS.  Fasteners sold by the Company include screws, bolts, nuts,
washers, rings, pins, rivets and staples. These items come in a variety of
materials, sizes, platings, and shapes. The variety is driven by the end-use
requirement or specification of the fastener, such as strength, resistance to
corrosion, reusability, and many other factors. The Company's sales and
purchasing departments have extensive knowledge of the available products
offered by fastener manufacturers, and play an important role in assisting OEMs
to select the appropriate fastener for a given application. Some of the more
common variable characteristics of the fasteners sold by the Company include:

         o   Materials -- The materials used in the manufacture of fasteners
             include steel, brass, aluminum, nylon, bronze, stainless steel,
             titanium, copper, polypropylene, alloys and other materials. Most
             of these materials come in different grades with each having a
             unique set of properties.

         o   Sizes -- The sizes vary by length, outside diameter, depth of the
             threads, threads per inch or centimeter and pitch, or angle, of the
             threads.

         o   Platings -- Platings may be applied to enhance the properties of a
             given metal, and include zinc, cadmium, chrome, nickel, organic and
             other materials.

         o   Shapes -- The range of shapes is broad, including hex head, U-bolt,
             L-bolt, shouldered, eye bolt, external tooth, internal tooth and
             many others.

     OTHER SMALL PARTS.  The Company also distributes other small parts used by
OEMs to assemble their products. These items include standoffs, inserts, clamps,
spacers, springs, brackets, electrical connectors, small molded parts, cable
ties, plugs, hoses, fittings and other small parts. Like fasteners, these parts
come in many shapes, sizes and materials depending upon the designated end-use.
OEMs are increasingly requesting that the Company provide these parts because
they are often used during the manufacturing or assembly process in conjunction
with the fasteners supplied by the Company.

SERVICES

     In connection with its sale of fasteners and other small parts, the Company
also provides a wide range of value-added services to OEMs. The OEMs' demand for
these services is driven by the reduction in costs achievable through the use of
such services. These value-added services also benefit the Company by further
integrating the Company into its customers' process. The Company's services
include:

          INVENTORY PROCUREMENT AND MANAGEMENT SYSTEMS.  Increasingly,
     manufacturers are outsourcing their inventory management needs to
     distributors. These services range from installing a simple inventory bin
     card system to developing a complete turn-key inventory management system
     with full-time staff. These inventory systems are designed to meet the
     specific needs of the Company's

                                       36
<PAGE>
     customers. They range in sophistication from helping the OEM set
     appropriate order quantities and frequencies to delivering the correct
     fastener or small part to the assembly floor on a JIT basis. In some cases,
     the Company utilizes computer systems deployed at the OEM's sites to
     facilitate the management of the fastener and parts inventories. Inventory
     replenishment services and product consolidation services decrease the
     number of invoices and vendors, lower inventory carrying cost, and allow
     customers to focus on their core manufacturing business.

          COMPREHENSIVE PRODUCT AVAILABILITY.  OEMs have reduced their operating
     costs by reducing the number of suppliers they use. The Company provides a
     wide array of fasteners and other small parts and will, upon a customer's
     request, stock additional parts. As a result, the Company's customers are
     able to reduce the number of distributors they use.

          KIT SERVICES.  OEMs often request that the Company package several
     fasteners or parts into a package or "kit." A common use of this service
     is to supply fastener kits included with products the retail consumer is
     required to assemble such as lawn mowers, bicycles and furniture. The use
     of kits has also expanded into the manufacturing environment. Manufacturers
     frequently desire to have several related fasteners or components arrive at
     the assembly line in a single package; this ensures that all of the parts
     arrive at the same time and that no part will be missed in the installation
     process. This "kit" process aids the manufacturer by decreasing the
     number of distributors needed and improves productivity by having the
     fasteners delivered to the assembly line with the other related parts. Kit
     services improve the efficiency and effectiveness of the manufacturing line
     and decreases the number of stock outs and subsequent manufacturing line
     stoppages.
   
          QUALITY ASSURANCE SERVICES.  These services involve the testing of
     fasteners to ensure they meet the specifications stated by the
     manufacturer. Although fasteners are not a significant part of the costs in
     a product, they are often critical components whose failure can cause the
     entire product to fail. As a result, many OEMs require strict quality
     control with respect to the fasteners. Certain of the Founding Companies
     have installed specialized equipment and laboratories and hired trained
     technicians to perform quality control tests on some of their fastener
     products. Quality assurance services lower the warranty costs of the OEMs.
     The Company operates four labs to test fasteners. The labs can test
     metallurgy, size consistency, corrosion and strength as well as other
     properties. Additionally, two of the Founding Companies are ISO-9002
     certified and the remaining three are in the process of becoming certified
     under ISO-9002 or a comparable standard. The Company expects the
     substantial majority of its currently uncertified locations to be ISO
     compliant or certified in 1998.

          PRODUCT ENHANCEMENT SERVICES.  In order to meet the exacting
     requirements of customers, the Company maintains relationships with vendors
     that provide plating, galvanizing and coating services. These services are
     used to enhance in-stock fasteners in order to meet the specific
     requirements of OEMs. The ability of the Company to manage the process and
     quickly respond to small orders enhances the relationship with the
     Company's customers.
    
          SUB-ASSEMBLY SERVICES.  Customers may request that two or more parts
     in a kit be pre-assembled into a single unit prior to being placed in the
     kit. These services are closely related to the kit services offered by the
     Company and are offered at the request of customers. Similar to kits, the
     sub-assembly services improve the productivity of the OEM's manufacturing
     line.

          ENGINEERING SERVICES.  Upon a customer's request, the Company will
     provide advice regarding the types of fasteners to use in a product. These
     services are often used by customers during early product development or
     re-engineering to decrease the production cost, improve the assembly
     process or enhance the product quality. The Company works with its
     customers' engineering departments to select the appropriate fasteners and
     components based upon the specifications of the customer. These services
     often lower the customer's cost by reducing the number of fasteners
     required to assemble the product, replacing expensive special fasteners
     with less expensive standards or identifying different coatings to improve
     quality.

          EDI SERVICES.  The Company offers a wide range of options with respect
     to the type and level of EDI services available to its customers. In
     addition to offering invoice and payment options, the

                                       37
<PAGE>
     Company can also offer its customers direct access to its current
     inventory, images of fasteners with specifications, and the ability to
     enter an order directly into the Company's system.

CUSTOMERS
   
     The Company sells fasteners and other small parts to more than 2,600
customers in over 25 countries. The customers manufacture a wide variety of
products including diesel engines, locomotives, power turbines, motorcycles,
telecommunications equipment, refrigeration equipment and aerospace equipment.
For the nine months ended September 30, 1997, the Company had net sales of
$112.8 million. The Company's ten largest customers, including Cummins Engine
Company, General Electric Corporation, Harley-Davidson, Inc., the Hughes
Aircraft subsidiary of General Motors Corporation, The Trane Company, Lockheed
Martin Corporation, and The Boeing Company, represented approximately 45% of the
Company's net sales in the nine months ended September 30, 1997. The Company has
been selling fasteners and small parts to these customers for an average of 12
years. Cummins Engine Company and its affiliates accounted for approximately 17%
of the Company's net sales in the nine months ending September 30, 1997. No
other customer represented more than 9% of the Company's net sales in the nine
months ended September 30, 1997. All of the Company's contracts with its
customers for the supply of fasteners and parts may be canceled by either party
on no more than 60 days notice. The Company accepts returns of fasteners and
other small parts and issues a credit in exchange for such returns.
Historically, returns have not been of an amount to materially affect the
Company's business. Approximately 8% of the Company's net sales during 1997 were
to customers or customer locations outside of the U.S. Several of the Company's
customers have international operations and some of them have requested that the
Company provide products and services to them in their foreign locations.
Historically, resource constraints have limited the Founding Companies' ability
to expand internationally and therefore the Founding Companies have not been
able to capitalize on these opportunities. However, the Company anticipates
aggressively pursuing these international opportunities.
    
     The following table sets forth information with respect to the Founding
Companies' estimated combined net sales by end-user industry base for the nine
months ended September 30, 1997:

BACKLOGS

     The Company does not have any significant backlog of orders; as noted
above, all of the Company's contracts for the supply of fasteners and parts may
be canceled by either party on no more than 60 days notice.
    
SALES AND MARKETING

     The Company utilizes a sales force comprised of 65 sales people. The
primary responsibilities of the sales force are to:

      o   Identify potential customers;

      o   Educate the customers about the Company's products, services and
          potential value;

                                       38
<PAGE>
      o   Manage the transition from existing vendors or systems to the
          Company's systems, products and services;

      o   Conduct follow-up sessions to identify additional product and service
          possibilities;

      o   Furnish product advice and options for specific customers
          requirements; and

      o   Resolve customers' problems and concerns.

     The Company expects to focus on marketing its products and services
primarily to mid- to large-size OEMs. The Company generally targets those OEMs
that could achieve significant cost savings from the products and services
offered by the Company; these would include OEMs that (i) maintain substantial
inventories of fasteners and components; (ii) utilize multiple vendors but wish
to decrease that number; (iii) experience a significant number of stockouts;
(iv) desire to improve the quality and reliability of their products; or (v)
desire to improve the efficiency and effectiveness of the manufacturing process.
The Company believes that its commitment to consistent quality and service has
enabled it to develop and maintain long-term relationships with existing
customers, while expanding its market penetration through the use of its sales
and marketing program.

DELIVERY

     The Company utilizes several forms of transportation to deliver its
products to its customers depending upon the urgency and frequency of delivery,
the customer's preference and cost. The Company primarily utilizes several
common carriers to deliver products to its customers. The cost of transportation
is generally paid by the customer. The Company believes that by maintaining
relationships with several carriers, it can effectively avoid the impact caused
by any one carrier ceasing operations. The Company does not believe that it is
materially dependent on any single transportation service or carrier and that it
currently maintains good relationships with all of its common carriers. The
Company operates 24 distribution and sales facilities across the U.S.

SUPPLIERS

     The fasteners and small parts sold by the Company are manufactured by over
2,000 suppliers located in more than 16 countries. The Company purchases
fasteners and small parts directly from manufacturers or, to a lesser degree,
from authorized distributors. During the nine months ended September 30, 1997,
the Company purchased no more than 5% of its fasteners and small parts from any
single source. The Company's decision to purchase from a specific supplier is
based on product specifications, quality, reliability of delivery, production
lead times and price.

     The Company anticipates reviewing its supplier base after completion of the
Acquisitions and believes that by reorganizing its supplier base, it will be
able to purchase fasteners and other small parts in sufficient volumes to
achieve improved service and pricing. The Company believes that it is not
materially dependent on any single supplier and that it currently maintains good
relationships with all of its suppliers.

COMPETITION

     The Company is engaged in a highly fragmented and competitive industry.
Competition is based primarily on service, quality, and geographic proximity.
The Company competes with a large number of fastener distributors on a regional
and local basis, some of which may have greater financial resources than the
Company and some of which are public companies or divisions of public companies.
The Company may also face competition for acquisition candidates from these
companies, some of whom have acquired fastener distribution businesses during
the past decade. Other smaller fastener distributors may also seek acquisitions
from time to time.

     The Company believes that it will be able to compete effectively because of
its significant number of locations, geographic diversity, knowledgeable and
trained sales force, integrated computer systems, modern equipment, broad-based
product line, long-term customer relationships, combined purchasing volume and
operational economies of scale. The Company intends to seek to differentiate
itself from its competition in terms of service and quality by investing in
systems and equipment and by offering a broad

                                       39
<PAGE>
range of products and services as well as through its entrepreneurial culture
and decentralized operating structure.

MANAGEMENT INFORMATION SYSTEMS

     Each of the Founding Companies operates a management information system
that is used to purchase, monitor and allocate inventory throughout its
facilities. The Company believes that these systems enable it to manage
inventory costs effectively and to achieve appropriate inventory turnover rates.
All of these systems include computerized order entry, sales analysis, inventory
status, invoicing and payment, and all but one includes bar-code tracking. These
systems are designed to improve productivity for both the Company and its
customers. All of the Founding Companies use EDI, through which they offer their
customers a paperless electronic process for order entry, shipment tracking,
customer billing, remittance processing and other routine matters.

     In connection with developing its internal Company-wide systems following
the Offering, the Company expects to draw upon the best features of the existing
systems that have been utilized by the Founding Companies. Once the systems of
the Founding Companies are integrated, certain of the information systems will
operate over a wide area network, and the real-time information system will
allow each warehouse and sales center to share information and monitor daily
progress relating to sales activities, credit approval, inventory levels, stock
balancing, vendor returns, order fulfillment, and other measures of performance.

GOVERNMENT REGULATION

     The Fastener Quality Act (the "Fastener Act") was signed into law by
President Bush on November 16, 1990 and was subsequently amended in March 1996.
Due to a lack of accredited testing facilities required under the Fastener Act,
the implementation date has been delayed until May 26, 1998. The Fastener Act is
intended to protect the public safety by deterring the introduction of
non-conforming fasteners into commerce and by improving the traceability of
fasteners. Generally, the Fastener Act covers fasteners including screws, nuts,
bolts or studs with internal or external threads and load indicating washers
with nominal diameters of greater than approximately one quarter inch, which
contain metal or are held out as meeting a standard or specification that
requires through-hardening. The Fastener Act also covers fasteners and washers
that are marked with a grade identification required by a specification or
standard. An estimated 25% to 55% of currently available fasteners meet this
definition and are therefore subject to the Fastener Act's requirement.

     Fastener distributors such as the Company are subject to the Fastener Act.
The Fastener Act places responsibility on fastener manufacturers and
distributors to ensure that fasteners conform to the standards and
specifications to which the manufacturer represents it has been manufactured by
having them tested in a laboratory accredited under the Fastener Act. Persons
who significantly alter fasteners must mark the fasteners so as to permit
identification of the source of the alteration. Further, the Fastener Act
prohibits manufacturers and distributors from commingling like fasteners from
more than two different lots in the same container during packaging.

     The Company currently operates four quality control labs at its facilities
and believes it will not be obligated to make any significant investment to
comply with the Fastener Act. The Company is applying for accreditation of its
laboratories under the Fastener Act. The Company anticipates that the majority
of any additional costs resulting from compliance with the Fastener Act will be
included in the prices to its customers. Some small distributors that are unable
to invest in the quality control equipment or services required to comply with
the Fastener Act may be forced to discontinue or reduce the parts of their
business that become subject to the Fastener Act.
   
     The Company's operations are subject to various federal, state and local
laws and regulations, including those relating to worker safety and protection
of the environment. The Company is a distributor and does not generally engage
in manufacturing. As a result, environmental laws generally have a minimal
effect on its operations. The Company believes it is in substantial compliance
with applicable regulatory requirements.
    
                                       40
<PAGE>
EMPLOYEES

     At September 30, 1997, the Company had approximately 516 employees. The
Company is a party to one collective bargaining agreement covering approximately
nine employees. The Company believes that its relationship with employees is
good.

PROPERTIES
   
     The Company operates 24 distribution and sales facilities throughout the
United States. These facilities range in size from 500 square feet to 90,000
square feet, and generally consist of warehouse space with a small amount of
associated office space. Four of the facilities include laboratory space for
quality testing. All of the facilities are leased. The Company's leases expire
between 1998 and 2012. The Company believes that suitable replacement space will
be available as required. Additional detail regarding certain leases is
contained herein under "Certain Transactions -- Transactions Involving Certain
Officers, Directors and Stockholders -- Leases of Real Property by Founding
Companies." The Company believes that its current facilities are adequate for
its expected needs over the next several years. However, the Company may add new
facilities as a result of acquisitions or due to a customer's request for an
on-site or local facility.

     The Company's corporate headquarters are located in space subject to a
short-term lease in Houston, Texas. The Company is in the process of obtaining
office space in Houston, Texas under a longer term lease for its corporate
headquarters.
    
LEGAL PROCEEDINGS

     The Company is not a party to any material pending legal proceedings, other
than ordinary routine litigation incidental to its business that management
believes would not have a material adverse effect on its business, financial
condition or results of operations.

DIRECTORS' COMPENSATION

     Directors who are employees of the Company do not receive additional
compensation for serving as directors. Each director who is not an employee of
the Company receives an annual fee of $16,000 paid in equal quarterly amounts.
Directors of the Company are reimbursed for out-of-pocket expenses incurred in
attending meetings of the Board of Directors or committees thereof, and for
other expenses incurred in their capacity as directors of the Company. Each
non-employee director will receive stock options to purchase 15,000 shares of
Common Stock upon election to the Board of Directors and an annual grant of
5,000 options. See "-- Stock Plan."

EXECUTIVE COMPENSATION
   
     The Company was incorporated in March 1997 and, prior to the Offering, has
not conducted any operations other than activities related to the Acquisitions
and the Offering. The Company anticipates that during 1998 annualized base
salaries of each of its most highly compensated executive officers, Messrs.
Baldwin, Fatica, Taten and Fontana, will be $150,000 and for Mr. Jackson,
$100,000. Options for a total of 185,000, 100,000, 85,000 and ______ shares of
Common Stock at the initial public offering price have been granted to Messrs.
Baldwin, Taten, Fontana and Jackson, respectively. Thirty percent (30%) of the
options vest on the second anniversary of the employment agreements and the
remainder vest on the third anniversary.
    
EMPLOYMENT AGREEMENTS
   
     The Company has entered into employment agreements with each executive
officer of the Company that prohibit such officers from disclosing the Company's
confidential information and trade secrets and generally restrict these
individuals from competing with the Company for a period of two years after the
termination of their respective employment agreements. Mr. Baldwin's employment
agreement has an initial term of five years. The agreements for Messrs. Taten
and Fontana have an initial term of three years and the agreement for Mr.
Jackson has an initial term of one year. All of the employment agreements are
terminable by the Company for "good cause" upon ten days' written notice and
without "cause" or for "good reason" by the officer upon fourteen days'
written notice. All employment agreements provide that if the officer's
employment is terminated by the Company without "good cause," such officer
will be entitled to receive a lump-sum severance payment at the effective time
of termination.

     The employment agreements of Messrs. Baldwin, Taten and Fontana contain
certain provisions concerning a change-in-control of the Company, including the
following: (i) in the event that the executive is not notified by the acquiring
company that it will assume the Company's obligations under the employment
agreement at least five days in advance of the transaction giving rise to the
change in control, the change in control will be deemed a termination of the
employment agreement by the Company without "cause," and the provisions of the
employment agreement governing the same will apply, except that the severance
amount otherwise payable (discussed in the preceding paragraph) shall be tripled
and the provisions which restrict competition with the Company shall not apply;
and (ii) in any change-of-control situation, such officer may elect to terminate
his employment by giving five days' written notice prior to the anticipated
closing of the transaction giving rise to the change-in-control, which will be
deemed a termination of the employment agreement by the Company without
"cause," and the provisions of the employment agreement governing the same
will apply, except that the severance amount otherwise payable shall be doubled
and the time period during which such officer is restricted from competing with
the Company will be eliminated. The change-of-control provisions in the
employment agreements may discourage bids to acquire the Company or reduce the
amount an acquiror is willing to pay for the Company.
    
STOCK PLAN

     The Board of Directors has adopted, and the stockholders of the Company
have approved, the Pentacon, Inc. 1998 Stock Plan (the "Stock Plan"). The
purpose of the Stock Plan is to provide directors, officers, key employees and
certain other persons who will be instrumental in the success of the Company

                                       44
<PAGE>
   
or its subsidiaries with additional incentives by increasing their proprietary
interest in the Company. The aggregate amount of Common Stock with respect to
which options may be granted may not exceed 1,700,000 shares (subject to
adjustment to reflect stock splits).

     The Stock Plan is administered by the Compensation Committee, which is
composed of non-employee directors (the "Committee"). Subject to the terms of
the Stock Plan, the Committee generally determines to whom options will be
granted and the terms and conditions of option grants. Options granted under the
Stock Plan may be either non-qualified stock options, or may qualify as
incentive stock options ("ISOs"), provided that the aggregate fair market
value (determined at the time the ISO is granted) of the Common Stock with
respect to which ISOs are exercisable for the first time by any employee during
any calendar year under all plans of the Company and any parent or subsidiary
corporation shall not exceed $100,000. The exercise price of any option may not
be less than the fair market value of the underlying Common Stock as of the date
of grant and no employee or consultant may receive an option in any year to
purchase more than 250,000 shares of Common Stock. The Committee determines the
period over which options become exercisable, provided that all options become
immediately exercisable upon death of the grantee or upon a change-in-control
(as defined in the Stock Plan) of the Company.

     The Stock Plan also provides for automatic option grants to directors who
are not otherwise employed by the Company or its subsidiaries. Upon commencement
of service, a non-employee director will receive a non-qualified option to
purchase 15,000 shares of Common Stock, and continuing non-employee directors
annually will receive options to purchase 5,000 shares of Common Stock. Options
granted to non-employee directors are immediately exercisable in full (subject
to applicable securities laws).

     Options which are not exercisable at the time of a voluntary termination of
the grantee's employment (or directorship) or in the case of a termination "for
cause" are immediately forfeited. In no event may an ISO granted to a control
person (as defined in the Stock Plan) be exercisable more than five years from
the date of grant. Each option granted to a non-employee director shall have a
term of ten years.
    
     Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"), places a $1 million cap on the deductible compensation that can be
paid to certain executives of publicly traded corporations. Amounts that qualify
as "performance based" compensation under Section 162(m)(4)(C) of the Code are
exempt from the cap and do not count toward the $1 million limit. Generally,
options granted with an exercise price at least equal to the fair market value
of the shares of Common Stock on the date of grant will qualify as performance
based.

     Upon exercise of a non-qualified option, the optionee generally will
recognize ordinary income in the amount of the "option spread" (the difference
between the market value of the option shares at the time of exercise and the
exercise price), and the Company is generally entitled to a corresponding tax
deduction (subject to certain withholding requirements). When an optionee sells
shares issued upon the exercise of a non-qualified stock option, the optionee
realizes a short-term or long-term capital gain or loss, depending on the length
of the holding period but the Company is not entitled to any tax deduction in
connection with such sale.

     An optionee will not be subject to federal income taxation upon the
exercise of ISOs granted under the Stock Plan, and the Company will not be
entitled to a federal income tax deduction by reason of such exercise. A sale of
shares of Common Stock acquired by exercise of an ISO that does not occur within
one year after the exercise or within two years after the grant of the option
generally will result in the recognition of long-term capital gain or loss in
the amount of the difference between the amount realized on the sale and the
exercise price, and the Company will not be entitled to any tax deduction in
connection therewith. If a sale of shares of Common Stock acquired upon exercise
of an ISO occurs within one year from the date of exercise of the option or
within two years from the date of the option grant (a "disqualifying
disposition"), the optionee generally will recognize ordinary compensation
income equal to the lesser of (i) the excess of the fair market value of the
shares on the date of exercise of the options over the exercise price, or (ii)
the excess of the amount realized on the sale of the shares over the exercise
price. Any amount realized on a disqualifying disposition in excess of the
amount treated as ordinary compensation income will be a long-term or a
short-term capital gain, depending upon the length of time the shares

                                       45
<PAGE>
were held. The Company generally will be entitled to a tax deduction on a
disqualifying disposition corresponding to the ordinary compensation income
recognized by the participant.

                              CERTAIN TRANSACTIONS

ORGANIZATION OF THE COMPANY

     During 1997, members of the management team and certain consultants were
assembled by
McFarland, Grossman Capital Ventures II, L.C. ("MGCV") to pursue the
consolidation of the Founding Companies. MGCV, an investment entity formed to
focus on consolidations in highly-fragmented industries, provided the Company
with expertise regarding the consolidation process and advanced the Company the
capital needed to pay organizational and offering expenses.
   
     In connection therewith, on November 18, 1997, Pentacon sold 200,000,
125,000 and 125,000 shares of Common Stock to Messrs. Baldwin, Taten and
Fontana, respectively, of the Company for $0.01 per share. As a result, the
Company has recorded non-recurring, non-cash compensation charges of $4.7
million in the fourth quarter of 1997, representing the difference between the
amount paid for the shares and the estimated initial public offering price net
of a twenty percent marketability discount. In February 1997, the Company also
granted two consultants warrants to purchase an aggregate of 50,000 shares of
Common Stock at the lesser of $8.00 or 60% of the public offering price. The
consultants provided business and legal consulting services for the Company in
connection with its formation in the first four months of 1997.
    
     The Company has agreed to reimburse MGCV for expenses incurred by MGCV in
connection with the Acquisitions and the Offering. The Company has agreed to pay
Donald Luke, a manager of MGCV, a success fee of $100,000 upon consummation of
the Offering. The Company will pay McFarland, Grossman & Company, Inc.
("McFarland, Grossman"), an affiliate of MGCV, customary fees in connection
with its placement of the Company's senior debt; the Company has also engaged
McFarland, Grossman, on customary terms, to provide financial advice regarding
acquisitions during the first four months after the Offering.

     Simultaneously with the closing of the Offering, the Company will acquire
by merger all of the issued and outstanding capital stock of the Founding
Companies, at which time each Founding Company will become a wholly owned
subsidiary of the Company. The aggregate consideration that will be paid by the
Company to acquire the Founding Companies consists of (i) approximately $28.7
million in cash and (ii) 6,720,000 shares of Common Stock. In addition, the
Company intends to repay approximately $19.5 million of the indebtedness of the
Founding Companies, including approximately $14.4 million from the proceeds of
the Offering.

     The following table sets forth for each Founding Company the approximate
consideration to be paid to the stockholders of the Founding Companies (i) in
cash and (ii) in shares of Common Stock, in each case subject to adjustments
through the date of the consummation of the Acquisition for the amount of S
corporation earnings previously taxed to stockholders of certain of the Founding
Companies.

     Immediately prior to consummation of the Acquisitions, certain of the
Founding Companies will make distributions estimated to be approximately $3.6
million, representing S corporation earnings previously

                                       46
<PAGE>
taxed to their respective stockholders. The amount of such distributions (in
excess of estimated shareholder tax liabilities for 1997 and 1998) shall be
deducted from the cash payments indicated in the table above.

     In connection with the Acquisitions, and as consideration for their
interests in the Founding Companies, certain officers, directors and holders of
more than 5% of the outstanding shares of the Company, together with trusts for
which they act as trustees, will receive cash and shares of Common Stock of the
Company as follows. These amounts do not include any S corporation
distributions.

     The consummation of each Acquisition is subject to customary conditions.
These conditions include, among others, the accuracy on the closing date of the
Acquisitions of the representations and warranties by the Founding Companies,
their principal stockholders and by the Company; the performance by each of the
parties of their respective covenants; and the nonexistence of a material
adverse change in the results of operations, financial condition or business of
each Founding Company.

     Certain of the Founding Companies have incurred indebtedness which has been
personally guaranteed by their stockholders or by entities controlled by their
stockholders. At September 30, 1997, the aggregate amount of indebtedness of
these Founding Companies that was subject to personal guarantees was
approximately $19.5 million. The Company intends to use a portion of the net
proceeds from this Offering, together with borrowings available from the
Company's anticipated revolving credit facility, to repay substantially all of
the indebtedness of the Founding Companies.

     There can be no assurance that the conditions to the closing of the
Acquisitions will be satisfied or waived or that the agreements relating to the
Acquisitions will not be terminated prior to the closing. If any of the
Acquisitions is terminated for any reason, the Company does not intend to
consummate the Offering on the terms described herein.

     Pursuant to the agreements relating to the Acquisitions, all significant
stockholders of each of the Founding Companies have agreed not to compete with
the Company for a period of five years commencing on the date of closing of the
Acquisitions.

TRANSACTIONS INVOLVING CERTAIN OFFICERS, DIRECTORS AND STOCKHOLDERS

  LEASES OF REAL PROPERTY BY FOUNDING COMPANIES

     Following the Acquisitions, Alatec will continue to lease its facilities
located in Chatsworth, California from Mr. List, who will become a director of
the Company upon consummation of the Offering. The lease provides for a total
annual rent of $462,840 with the term of the lease expiring in March 2012.
Alatec shall also pay taxes and utilities on the leased premises. The rent will
be adjusted in accordance with the Consumer Price Index ("CPI") subject to a
minimum of 4% and a maximum of 8%. In addition, Alatec will continue to lease
its warehouse in Fremont, California from FDR Properties, an entity controlled
and partially owned by Mr. List. This lease expires August 31, 1998 and provides
for an annual rent of $114,336. Alatec shall also pay taxes and utilities on
those premises. The Company will also continue to lease from the List Family
Trust an office and warehouse in Chatsworth, California. The lease provides for
an annual rental of $170,832 and terminates in October, 2012. Alatec shall also

paid in connection with the acquisition of Maumee.

  OTHER TRANSACTIONS

     Mr. List owns approximately 50% of a supplier from which the Company
purchased approximately $1.1 million of products during the nine months ended
September 30, 1997. The Company believes all such purchases have been at fair
market prices. The Company anticipates continuing to purchase products from the
supplier in the future so long as the prices and terms remain competitive with
those of alternative suppliers.

     In November 1997, Mr. Grossman and Mr. Pugh, each principals in MGCV,
became officers of Alatec in order to assist in, facilitate and expedite the
audit process in connection with the Offering. Alatec and Mr. List, its sole
stockholder, have agreed to indemnify Messrs. Grossman and Pugh against various
claims, damages, costs and expenses which might be incurred by them as officers
of Alatec, including their execution of representation letters to Alatec's
accountants.

     The Company has agreed to permit Jack L. Fatica to acquire certain life
insurance policies from AXS at a price to be mutually agreed upon, which will
approximate the fair market value of the policies.

COMPANY POLICY

     Any future transactions with directors, officers, employees or affiliates
of the Company are anticipated to be minimal, and must be approved in advance by
a majority of disinterested members of the Board of Directors.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL
   
     The Company's authorized capital stock consists of 50,000,000 shares of
Common Stock, par value $0.01 per share, 1,000,000 shares of Restricted Common
Stock, par value $0.01 per share and 10,000,000 shares of Preferred Stock, par
value $0.01 per share. After giving effect to the Acquisitions, there will be
9,550,000 shares of Common Stock outstanding, which will be held of record by 31
stockholders, 467,000 shares of Restricted Common Stock outstanding, which are
held of record by MGCV and no shares of Preferred Stock outstanding. After the
closing of the Offering, 13,323,585 shares of Common Stock will be issued and
outstanding and 1,070,000 shares of Common Stock will be reserved for issuance
upon exercise of outstanding options and warrants. The following summary of the
terms and provisions of the Company's capital stock does not purport to be
complete and is qualified in its entirety by reference to the Company's
Certificate of Incorporation and Bylaws, which have been filed as exhibits to
the Company's registration statement, of which this Prospectus is a part, and
applicable law.
    
COMMON STOCK

     The holders of Common Stock are each entitled to one vote for each share
held on all matters to which they are entitled to vote, including the election
of directors. The holders of Restricted Common Stock, voting together as a
single class, are entitled to elect one member of the Company's Board of
Directors and will be entitled to 0.25 of a vote per share on all other matters
on which the Common Stock is entitled to vote. Holders of Restricted Common
Stock are not entitled to vote on the election of any other directors. Upon
consummation of this Offering, the Board of Directors will be classified into
three classes as nearly equal in number as possible, with the term of each class
expiring on a staggered basis. The classification of the Board of Directors may
make it more difficult to change the composition of the Board of Directors and
thereby may discourage or make more difficult an attempt by a person or group to
obtain control of the Company. Cumulative voting for the election of directors
is not permitted. Any director, or the entire Board of Directors, may be removed
at any time, with cause, by a majority of the aggregate number of votes which
may be cast by the holders of outstanding shares of Common Stock and Restricted
Common Stock entitled to vote for the election of directors, provided, however,
that only the holders of the Restricted Common Stock may remove the director
such holders are entitled to elect.

     Subject to the rights of any then outstanding shares of Preferred Stock,
the holders of the Common Stock are entitled to such dividends as may be
declared in the discretion of the Board of Directors out of funds legally
available therefor. See "Dividend Policy." Holders of Common Stock are
entitled to share ratably in the net assets of the Company upon liquidation
after payment or provision for all liabilities and any preferential liquidation
rights of any Preferred Stock then outstanding. The holders of Common Stock have
no preemptive rights to purchase shares of stock of the Company. Shares of
Common Stock are not subject to any redemption provisions and are not
convertible into any other securities of the Company. All outstanding shares of
Common Stock are fully paid and nonassessable.
   
     Each share of Restricted Common Stock will automatically convert to Common
Stock on a share-for-share basis (i) in the event of a disposition of such share
of Restricted Common Stock by the holder thereof (other than a distribution
which is a distribution by a holder to its partners or beneficial owners, or a
transfer to a related party of such holder (as defined in Sections 267, 707, 318
and/or 4946 of the Internal Revenue Code of 1986, as amended)), (ii) in the
event any person acquires beneficial ownership of 30% or more of the outstanding
shares of Common Stock, or (iii) in the event any person offers to acquire 30%
or more of the total number of outstanding shares of Common Stock. After January
1, 2003, the Board of Directors may elect to convert any outstanding shares of
Restricted Common Stock into shares of Common Stock in the event 80% or more of
the originally outstanding shares of Restricted Common Stock have been
previously converted into shares of Common Stock.
    
                                       50
<PAGE>
PREFERRED STOCK

     The Preferred Stock may be issued from time to time by the Board of
Directors as shares of one or more classes or series. Subject to the provisions
of the Company's Amended and Restated Certificate of Incorporation and
limitations prescribed by law, the Board of Directors is expressly authorized to
adopt resolutions to issue the shares, to fix the number of shares and to change
the number of shares constituting any series, and to provide for or change the
voting powers, designations, preferences and relative, participating, optional
or other special rights, qualifications, limitations or restrictions thereof,
including dividend rights (including whether dividends are cumulative), dividend
rates, terms of redemption (including sinking fund provisions), redemption
prices, conversion rights and liquidation preferences of the shares constituting
any class or series of the Preferred Stock, in each case without any further
action or vote by the stockholders. The Company has no current plans to issue
any shares of Preferred Stock of any class or series.

     One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect the continuity of the Company's management.
The issuance of shares of Preferred Stock pursuant to the Board of Directors'
authority described above may adversely affect the rights of the holders of
Common Stock. For example, Preferred Stock issued by the Company may rank prior
to the Common Stock as to dividend rights, liquidation preference or both, may
have full or limited voting rights and may be convertible into shares of Common
Stock. Accordingly, the issuance of shares of Preferred Stock may discourage
bids for the Common Stock at a premium or may otherwise adversely affect the
market price of the Common Stock.

STATUTORY BUSINESS COMBINATION PROVISION

     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law ("Section 203"). Section 203 provides, with certain
exceptions, that a Delaware corporation may not engage in any of a broad range
of business combinations with a person or an affiliate, or an associate of such
person, who is an "interested stockholder" for a period of three years from
the date that such person became an interested stockholder unless: (i) the
transaction resulting in a person becoming an interested stockholder, or the
business combination, is approved by the Board of Directors of the corporation
before the person becomes an interested stockholder, (ii) the interested
stockholder acquired 85% or more of the outstanding voting stock of the
corporation in the same transaction that makes such person an interested
stockholder (excluding shares owned by persons who are both officers and
directors of the corporation, and shares held by certain employee stock
ownership plans), or (iii) on or after the date the person becomes an interested
stockholder, the business combination is approved by the corporation's board of
directors and by the holders of at least 66% of the corporation's outstanding
voting stock at an annual or special meeting, excluding shares owned by the
interested stockholder. Under Section 203, an "interested stockholder" is
defined as any person who is (i) the owner of 15% or more of the outstanding
voting stock of the corporation or (ii) an affiliate or associate of the
corporation and who was the owner of 15% or more of the outstanding voting stock
of the corporation at any time within the three-year period immediately prior to
the date on which it is sought to be determined whether such person is an
interested stockholder.

     A corporation may, at its option, exclude itself from the coverage of
Section 203 by including in its certificate of incorporation or by-laws by
action of its stockholders to exempt itself from coverage. The Company has not
adopted such an amendment to its Amended and Restated Certificate of
Incorporation or Bylaws.

LIMITATION ON DIRECTORS' LIABILITIES

     Pursuant to the Company's Amended and Restated Certificate of Incorporation
and under Delaware law, directors of the Company are not liable to the Company
or its stockholders for monetary damages for breach of fiduciary duty, except
for liability in connection with a breach of the duty of loyalty, for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, for dividend payments or stock repurchases illegal under
Delaware law or any transaction in which a director

                                       51
<PAGE>
has derived an improper personal benefit. The Company has entered into
indemnification agreements with its directors and executive officers which
indemnify such person to the fullest extent permitted by its Certificate of
Incorporation, its Bylaws and the Delaware General Corporation Law. The Company
also intends to obtain directors' and officers' liability insurance.
   
AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS

     The Company's Amended and Restated Certificate of Incorporation and Bylaws
include provisions that may have the effect of discouraging, delaying or
preventing a change in control of the Company or an unsolicited acquisition
proposal that a stockholder might consider favorable, including a proposal that
might result in the payment of a premium over the market price for the shares
held by stockholders. These provisions are summarized in the following
paragraphs.

     CLASSIFIED BOARD OF DIRECTORS.  The Amended and Restated Certificate of
Incorporation provides for the Board of Directors to be divided into three
classes of directors serving staggered three-year terms. The classification of
the Board of Directors has the effect of requiring at least two annual
stockholders meetings, instead of one, to replace a majority of members of the
Board of Directors.

     SUPERMAJORITY VOTING.  The Amended and Restated Certificate of
Incorporation requires the approval of the holders of at least 75% of the then
outstanding shares of the Company's capital stock entitled to vote thereon on,
among other things, certain amendments to the Amended and Restated Certificate
of Incorporation. The Board of Directors may amend, alter, change or repeal any
bylaws without the assent or vote of the stockholders, but any bylaws made by
the Board of Directors may be altered, amended or repealed upon the affirmative
vote of at least 66 2/3% of the stock entitled to vote thereon.

     AUTHORIZED BUT UNISSUED OR UNDESIGNATED CAPITAL STOCK.  The Company's
authorized capital, stock will consist of 50,000,000 shares of Common Stock,
1,000,000 shares of Restricted Common Stock, and 10,000,000 shares of preferred
stock. After the Offering, the Company will have outstanding 13,323,585 shares
of Common Stock and Restricted Common Stock (assuming the Underwriters'
over-allotment options are not exercised). The authorized but unissued (and in
the case of preferred stock, undesignated) stock may be issued by the Board of
Directors in one or more transactions. In this regard, the Company's Amended and
Restated Certificate of Incorporation grants the Board of Directors broad power
to establish the rights and preferences of authorized and unissued preferred
stock. The issuance of shares of preferred stock pursuant to the Board of
Directors' authority described above could decrease the amount of earnings and
assets available for distribution to holders of Common Stock and adversely
affect the rights and powers, including voting rights, of such holders and may
also have the effect of delaying, deferring or preventing a change in control of
the Company. The Board of Directors does not currently intend to seek
stockholder approval prior to any issuance of preferred stock, unless otherwise
required by law.

     SPECIAL MEETING OF STOCKHOLDERS.  The Bylaws provide that special meetings
of stockholders of the Company may only be called by the Chairman of the Board
of Directors upon the written request of the Board of Directors pursuant to a
resolution approved by a majority of the whole Board of Directors.

     STOCKHOLDER ACTION BY WRITTEN CONSENT.  The Amended and Restated
Certificate of Incorporation and Bylaws generally provide that any action
required or permitted by the stockholders of the Company must be effected at a
duly called annual or special meeting of the stockholders and may not be
effected by any written consent of the stockholders.

     NOTICE PROCEDURES.  The Bylaws establish advance notice procedures with
regard to stockholder proposals relating to the nomination of candidates for
election as director, the removal of directors and amendments to the Amended and
Restated Certificate of Incorporation or Bylaws to be brought before annual
meetings of stockholders of the Company. These procedures provide that notice of
such stockholder proposals must be timely given in writing to the Secretary of
the Company prior to the annual meeting. Generally, to be timely, notice must be
received at the principal executive offices of the Company not less than 80 days
prior to an annual meeting (or if fewer than 90 days' notice or prior public
disclosure of the date of the annual meeting is given or made by the Company,
not later than the tenth day following the date on which the notice of the date
of the annual meeting was mailed or such public disclosure was made). The
    
                                       52
<PAGE>
   
notice must contain certain information specified in the Bylaws, including a
brief description of the business desired to be brought before the annual
meeting and certain information concerning the stockholder submitting the
proposal.

     CHARTER PROVISIONS RELATING TO RIGHTS PLAN.  The Amended and Restated
Certificate of Incorporation authorizes the Board of Directors of the Company to
create and issue rights (the "Rights") entitling the holders thereof to
purchase from the Company shares of capital stock or other securities. The times
at which, and the terms upon which, the Rights are to be issued may be
determined by the Board of Directors and set forth in the contracts or
instruments that evidence the Rights. The authority of the Board of Directors
with respect to the Rights includes, but is not limited to, the determination of
(i) the initial purchase price per share of the capital stock or other
securities of the Company to be purchased upon exercise of the Rights, (ii)
provisions relating to the times at which and the circumstances under which
Rights may be exercised or sold or otherwise transferred, either together with
or separately from, any other securities of the Company, (iii) provisions which
adjust the number or excercise price of the Rights or amount or nature of the
securities or other property receivable upon exercise of the Rights, (iv)
provisions which deny the holder of a specified percentage of the outstanding
securities of the Company the right to exercise the Rights and/or cause the
Rights held by such holder to become void, (v) provisions which permit the
Company to redeem the Rights and (vi) the appointment of a rights agent with
respect to the Rights. If authorized by the Board of Directors, the Rights would
be intended to protect the Company's stockholders from certain non-negotiated
takeover attempts which present the risk of a change of control on terms which
may be less favorable to the Company's stockholder than would be available in a
transaction negotiated with and approved by the Board of Directors. The Board of
Directors believes that the interests of the stockholders generally are best
served if any acquisition of the Company or a substantial percentage of the
Company's Common Stock results from arm's-length negotiation and reflects the
Board of Directors' careful consideration of the proposed terms of a
transaction. In particular, the Rights if issued would be intended to help (i)
reduce the risk of coercive two-tiered, front-end loaded or partial offers which
may not offer fair value to all stockholders of the Company, (ii) deter market
accumulators who through open market or private purchases may achieve a position
of substantial influence or control without paying to stockholders a fair
control premium and (iii) deter market accumulators who are simply intereted in
putting the Company "in play."
    
TRANSFER AGENT AND REGISTRAR
   
     The Transfer Agent and Registrar for the Common Stock is American
Securities Transfer & Trust Company, Inc.
    
                        SHARES ELIGIBLE FOR FUTURE SALE
   
     The market price of the Common Stock could be adversely affected by the
sale of substantial amounts of Common Stock in the public market. Upon
consummation of the Offering there will be 13,323,585 shares of Common Stock
issued and outstanding. All of the 3,773,585 shares sold in the Offering, except
for shares acquired by affiliates of the Company, will be freely tradeable.
    
     Simultaneously with the closing of the Offering, the stockholders of the
Founding Companies received, in the aggregate, 6,720,000 shares of Common Stock
as a portion of the consideration for their businesses. Certain other
stockholders of the Company held, in the aggregate, an additional 2,830,000
shares of Common Stock. None of these 9,550,000 shares were issued in a
transaction registered under the Securities Act, and, accordingly, such shares
may not be sold except in transactions registered under the Securities Act or
pursuant to an exemption from registration, including the exemption contained in
Rule 144 under the Securities Act.

     In general, under Rule 144 as currently in effect, a person, or persons
whose shares are aggregated, who has beneficially owned his or her shares for at
least one year, or a person who may be deemed an "affiliate" of the Company
who has beneficially owned shares for at least one year, would be entitled to
sell within any three-month period a number of shares that does not exceed the
greater of 1% of the then

                                       53
<PAGE>
outstanding shares of the Common Stock or the average weekly trading volume of
the Common Stock during the four calendar weeks preceding the date on which
notice of the proposed sale is sent to the Securities and Exchange Commission.
Sales under Rule 144 are also subject to certain manner of sale provisions,
notice requirements and the availability of current public information about the
Company. A person who is not deemed to have been an affiliate of the Company at
any time for 90 days preceding a sale and who has beneficially owned his shares
for at least two years would be entitled to sell such shares under Rule 144
without regard to the volume limitations, manner of sale provisions, notice
requirements or the availability of current public information about the
Company.
   
     The Company has authorized the issuance of up to 1,700,000 shares of its
Common Stock in accordance with the terms of the 1998 Stock Plan. Options to
purchase 370,000 shares have been granted to certain officers of Pentacon under
the 1998 Stock Plan and it is anticipated that options to purchase 600,000
shares of Common Stock will be granted upon closing of the Offering to certain
employees of the Founding Companies. The Company intends to file a registration
statement on Form S-8 under the Securities Act registering the issuance of
shares upon exercise of options granted under the 1998 Stock Plan. As a result,
such shares will be eligible for resale in the public market.
    
     The Company currently intends to file a registration statement covering
3,350,000 additional shares of Common Stock under the Securities Act for its use
in connection with future acquisitions. These shares generally will be freely
tradeable after their issuance by persons not affiliated with the Company unless
the Company contractually restricts their resale.

     The Company has issued to certain consultants warrants to purchase 50,000
shares of Common Stock with an exercise price equal to the lesser of $8.00 or
60% of the public offering price.

     The Company has agreed that it will not offer or sell any shares of Common
Stock or options, rights or warrants to acquire any Common Stock for a period of
180 days after the date of this Prospectus without the prior written consent of
Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"), except for shares
issued (i) in connection with acquisitions and (ii) pursuant to the Stock Plan.
Further, the Company's directors, officers, stockholders and substantially all
of the owners of the Founding Companies who beneficially own approximately
9,320,000 shares in the aggregate have agreed not to directly or indirectly
offer for sale, sell or otherwise dispose of any Common Stock for a period of
one year after the date of this Prospectus without the prior written consent of
DLJ.

     Prior to the Offering, there has been no established trading market for the
Common Stock, and no predictions can be made as to the effect that sales of
Common Stock under Rule 144, pursuant to a registration statement, or otherwise,
or the availability of shares of Common Stock for sale, will have on the market
price prevailing from time to time. Sales of substantial amounts of Common Stock
in the public market, or the perception that such sales could occur, could
depress the prevailing market price. Such sales may also make it more difficult
for the Company to issue or sell equity securities or equity-related securities
in the future at a time and price that it deems appropriate. See "Risk
Factors -- Shares Eligible for Future Sale."

     The former stockholders of the Founding Companies, after one year, and
certain officers, directors and stockholders holding in the aggregate 9,550,000
shares of Common Stock are entitled to certain rights with respect to the
registration of their shares of Common Stock under the Securities Act. If the
Company proposes to register any of its securities under the Securities Act,
such stockholders are entitled to notice of such registration and are entitled
to include, at the Company's expense, all or a portion of their shares therein,
subject to certain conditions. These registration rights will not apply to the
registration statement the Company intends to file for use in future
acquisitions.

                                  UNDERWRITING

     Subject to the terms and conditions of an Underwriting Agreement (the
"Underwriting Agreement"), the Underwriters named below, who are represented
by Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"), BT Alex. Brown
Incorporated and Schroder & Co. Inc. (collectively, the "Representatives"),
have severally agreed to purchase from the Company the respective numbers of
shares of Common Stock set forth opposite their names below.

                                        NUMBER OF
            UNDERWRITERS                  SHARES

Schroder & Co. Inc...................

     Total...........................
                                        ==========

     The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the shares of Common Stock
offered hereby are subject to approval by their counsel of certain legal matters
and to certain other conditions. The Underwriters are obligated to purchase and
accept delivery of all the shares of Common Stock offered hereby (other than
those shares covered by the over-allotment option described below) if any are
purchased.

     The Underwriters initially propose to offer the shares of Common Stock 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 dealers (including the
Underwriters) at such price less a concession not in excess of $       per
share. The Underwriters may allow, and such dealers may re-allow, to certain
other dealers a concession not in excess of $        per share. After the
initial offering of the Common Stock, the public offering price and other
selling terms may be changed by the Representatives at any time without notice.
The Underwriters do not intend to confirm sales to any accounts over which they
exercise discretionary authority.

     The Company has granted to the Underwriters an option, exercisable within
30 days after the date of this Prospectus, to purchase, from time to time, in
whole or in part, up to an aggregate of 566,038 additional shares of Common
Stock at the initial public offering price less underwriting discounts and
commissions. The Underwriters may exercise such option solely to cover
over-allotments, if any, made in connection with the Offering. To the extent
that the Underwriters exercise such option, each Underwriter will become
obligated, subject to certain conditions, to purchase its pro rata portion of
such additional shares based on such Underwriter's percentage underwriting
commitment as indicated in the preceding table.

     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.

     Each of the Company, its executive officers and directors and certain
stockholders of the Company has agreed, subject to certain exceptions noted
below, not to (i) offer, pledge, sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant to purchase or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock or (ii) enter into any swap or
other arrangement that transfers all or a portion of the economic consequences
associated with the ownership of any Common Stock (regardless of whether any of
the transactions described in clause (i) or (ii) is to be settled by the
delivery of Common Stock, or such other securities, in cash or otherwise) for a
period of 180 days after the date of this Prospectus without the prior written
consent of DLJ. In addition, during such period, the Company has also agreed not
to file any registration statement with respect to, and each of its executive
officers, directors and certain stockholders of the Company has agreed, except
as noted below, not to make any demand for, or exercise any right with respect
to, the registration of any shares of

                                       55
<PAGE>
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock without DLJ's prior written consent.

     The Underwriters have agreed to allow the Company to issue shares of Common
Stock in connection with acquisitions after the thirtieth day following the date
of the Prospectus and pursuant to the Stock Plan. In addition, the Company
intends to register 3,350,000 shares of Common Stock under the Securities Act
for use by the Company in future acquisitions. See "Shares Eligible For Future
Sale."

     Prior to the Offering, there has been no established trading market of the
Common Stock. The initial public offering price for the shares of Common Stock
offered hereby will be determined by negotiation among the Company and the
Representatives. The factors to be considered in determining the initial public
offering price include the history of and the prospects for the industry in
which the Company competes, the past and present operations of the Founding
Companies, the historical results of the operations of the Founding Companies,
the prospects for future earnings of the Company, the recent market prices of
securities of generally comparable companies and the general condition of the
securities markets at the time of the Offering.

     Application will be made to list the Common Stock on the New York Stock
Exchange (the "NYSE"). In order to meet the requirements for listing the
Common Stock on the NYSE, the Underwriters have undertaken to sell lots of 100
or more shares to a minimum of 2,000 beneficial owners.

     Other than in the United States, no action has been taken by the Company or
the Underwriters that would permit a public offering of the shares of Common
Stock offered hereby in any jurisdiction where action for that purpose is
required. The shares of Common Stock offered hereby may not be offered or sold,
directly or indirectly, nor may this Prospectus or any other offering material
or advertisements in connection with the offer and sale of any such shares of
Common Stock be distributed or published in any jurisdiction, except under
circumstances that will result in compliance with the applicable rules and
regulations of such jurisdiction. Persons into whose possession this Prospectus
comes are advised to inform themselves about and to observe any restrictions
relating to the Offering and the distribution of this Prospectus. This
Prospectus does not constitute an offer to sell or a solicitation of an offer to
buy any shares of Common Stock offered hereby in any jurisdiction in which such
an offer or a solicitation is unlawful.

     Certain employees of DLJ and BT Alex. Brown Incorporated are investors in
MGCV. Pursuant to the terms of the limited liability company agreement of MGCV,
upon completion of the Offering those employees will receive an aggregate of
69,231 shares of Common Stock (assuming an initial public offering price of
$      per share) and $225,000 of the proceeds of the Offering.

     In connection with the Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Stock. Specifically, the Underwriters may over-allot the Offering,
creating a syndicate short position. The Underwriters may bid for and purchase
shares of Common Stock in the open market to cover such syndicate short position

                     PENTACON, INC. AND FOUNDING COMPANIES
               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
                             BASIS OF PRESENTATION

     The following unaudited pro forma combined financial statements give effect
to the acquisition by Pentacon, Inc. ("Pentacon"), of the outstanding capital
stock of (a) Alatec Products, Inc. ("Alatec"), (b) AXS Solutions, Inc.
("AXS"), (c) Capitol Bolt & Supply, Inc. ("Capitol"), (d) Maumee Industries,
Inc. ("Maumee"), and (e) Sales Systems, Limited ("SSL") (together, the
"Founding Companies"). Pentacon and the Founding Companies are hereinafter
referred to as the "Company." These acquisitions (the "Acquisitions") will
occur simultaneously with the closing of Pentacon's initial public offering (the
"Offering") and will be accounted for using the purchase method of accounting.
Alatec, one of the Founding Companies, has been identified as the accounting
acquiror because its shareholder will receive the largest portion of voting
rights of the Company.

     These statements are based on the historical financial statements of
Pentacon, Inc., and the Founding Companies included elsewhere in the Prospectus.
The unaudited pro forma combined balance sheet gives effect to the Acquisitions
and the Offering as if they had occurred on September 30, 1997. The unaudited
pro forma combined statement of operations gives effect to these transactions as
if they were consummated on January 1, 1997.
   
     The Company has estimated the savings that it expects to be realized by
consolidating certain operations and general and administrative functions. To
the extent the owners and certain key employees of the Founding Companies have
agreed prospectively to reductions in salary, bonuses, benefits, and rent
expense paid to the owners, these reductions have been reflected in the
unaudited pro forma combined statement of operations. With respect to other
potential costs savings, the Company has not and cannot quantify these savings
until completion of the combination of the Founding Companies. It is anticipated
that these savings will be offset by the costs of being a publicly held company
and the incremental increase in costs related to the Company's new management.
However, these costs, like the savings that they offset, cannot be estimated at
this time. Neither the anticipated savings nor the anticipated costs have been
included in the pro forma combined financial information. In addition, the pro
forma combined statement of operations does not include an adjustment for a
nonrecurring, non-cash charge of $4.7 million for issuing common stock to
employees and officers of Pentacon. Such issuance will occur subsequent to
September 30, 1997 and prior to completion of the Offering and will be recorded
in the period in which it occurs. Upon completion of the Offering, a non-cash,
non-recurring charge of approximately $24.8 million based on a twenty percent
marketability discount from the estimated Offering price to the public will be
recorded in the income statement to reflect Offering expenses related to the
2,380,000 shares of common stock issued to MGCV. Both of these charges will
result in an equal increase in common stock and paid in capital.
    
     The pro forma adjustments are based on preliminary estimates, available
information, and certain assumptions and may be revised as additional
information becomes available. The unaudited pro forma financial data does not
purport to represent what the Company's financial position or results of
operations would actually have been if such transactions in fact had occurred on
those dates and are not representative of the Company's financial position or
results of operations for any future period. Since the Founding Companies were
not under common control or management, historical combined results may not be
comparable to, or indicative of, future performance. The unaudited pro forma
combined financial statements should be read in conjunction with the other
financial statements and notes thereto included elsewhere in this Prospectus.
See "Risk Factors" included elsewhere herein.

                         NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1997

1.  BUSINESS AND ORGANIZATION

     Pentacon, Inc., a Delaware corporation ("Pentacon" or the "Company"),
was organized on March 20, 1997 to (i) become a leading domestic and
international value-added distributor of fasteners and other small parts to
original equipment manufacturers ("OEMs"), (ii) provide related inventory
management services to OEMs and others, and (iii) pursue the consolidation of
the highly-fragmented fastener distribution industry. Pentacon intends to
acquire five businesses (the "Acquisitions"), contemporaneously complete an
initial public offering (the "Offering") of its common stock.

     Pentacon has not conducted any operations, and all activities to date have
related to the Offering and the Acquisitions. Initial capitalization of the
Company by McFarland, Grossman Capital Ventures II, L.C. ("MGCV"), was $1,000.
All expenditures to date have been funded by MGCV, on behalf of the Company. As
of September 30, 1997, costs of approximately $268,138 have been paid by MGCV on
behalf of the Company in connection with the Offering. Pentacon has treated
these costs as deferred offering costs. Pentacon is dependent upon the Offering
to execute the pending Acquisitions and to repay MGCV. The Company has agreed to
pay Donald Luke, a manager of MGCV, a success fee of $100,000 upon consummation
of the Offering. There is no assurance that the pending Acquisitions discussed
below will be completed or that Pentacon will be able to generate future
operating revenues.

  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 reported amounts in the financial statements. Actual
results could differ from those estimates.

  INCOME TAXES

     The Company has incurred a net operating loss since inception of which a
100% valuation allowance has been established for financial reporting purposes.
Accordingly no deferred tax asset has been recorded.

2.  STOCKHOLDERS' EQUITY

  COMMON STOCK

     Pentacon has entered into agreements whereby the total shares and warrants
to purchase shares of common stock of Pentacon held by MGCV, certain consultants
to MGCV, and management of the Company, will represent 30% of the total shares
outstanding immediately before completion of the Offering. Of these shares,
certain members of management will hold 4.7% of the total shares outstanding
immediately before completion of the Offering and MGCV will hold the remaining
shares. Based on these agreements and the estimated total shares to be
outstanding upon completion of the Offering, the shares presented herein have
been restated to effect 2,380-for-one stock split and an increase in authorized
shares of common stock to 50,000,000 voting shares and 1,000,000 non-voting
shares.

     In connection with the organization and initial capitalization of Pentacon,
the Company issued 2,380,000 shares of common stock to MGCV. In November 1997,
management of the Company acquired 450,000 shares of common stock for $0.01 per
share. As a result of the issuance of the 450,000 shares, the Company will
record a nonrecurring, non-cash compensation charge in November 1997 of
approximately $4.7 million, based on an estimated Offering price to the public
net of a twenty percent marketability discount. Upon completion of the Offering,
a non-cash, non-recurring charge of approximately $24.8 million based on a
twenty percent marketability discount from the estimated initial public offering
price will be recorded to reflect Offering expenses related to the 2,380,000
shares of common stock held by MGCV.

                                 PENTACON, INC.
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  RESTRICTED COMMON STOCK

     In December 1997, MGCV exchanged 367,000 shares of Common Stock for an
equal number of shares of restricted voting common stock ("Restricted Common
Stock"). The holder of Restricted Common Stock is entitled to elect one member
of the Company's Board of Directors and to 0.25 of one vote for each share held
on all other matters on which they are entitled to vote.

     Each share of Restricted Common Stock will automatically convert into
Common Stock on a share-for-share basis (a) in the event of a disposition of
such share of Restricted Common Stock by the holder thereof (other than a
disposition which is a distribution by a holder to its partners or beneficial
owners or a transfer to a related party of such holder (as defined)), (b) in the
event any person acquires beneficial ownership of 15% or more of the outstanding
shares of Common Stock of the Company, or (c) in the event any person offers to
acquire 15% or more of the total number of outstanding shares of Common Stock.

     After January 1, 2000, the Corporation may elect to convert any outstanding
shares of Restricted Common Stock into shares of Common Stock.

  WARRANTS

     At the date of the Company's organization, warrants were issued for 50,000
shares of common stock with an exercise price equal to the lesser of $8 per
share or 60% of the initial public offering price. These warrants were issued to
legal and investment advisors for a total of $50. As the Company was subject to
significant uncertainties, the value of the warrants and their underlying shares
was de minimus at that date and no value beyond the consideration received has
been assigned to them. The warrants may be exercised up to four years after the
consummation of the Offering.

  STOCK PLAN
   
     The board of directors of the Company intends to adopt the Pentacon, Inc.
1998 Stock Plan (the "Plan"). The Company anticipates that upon or shortly
after the consummation of its Offering that it will have granted options to
purchase up to 1.7 million shares of common stock. Subsequent to September 30,
1997 the Company has granted certain members of management options for 370,000
shares of common stock and intends to grant additional options for 600,000
shares of common stock with the exercise prices to be equal to the Offering
price. The Company will account for options issued to employees and nonemployee
directors under the Plan in accordance with APB Opinion No. 25 and, accordingly,
no compensation cost will be recognized to the extent that shares are issued at
the fair market value as of the date of grant. The Company will provide the pro
forma disclosure of net earnings per share in the notes to the financial
statements as if the fair value-based method of accounting has been applied to
awards as required by Statement of Financial Standard No. 123, ACCOUNTING FOR
STOCK-BASED COMPENSATION.
    
3.  NEW ACCOUNTING PRONOUNCEMENT

     In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, EARNINGS PER SHARE. For the Company, SFAS No. 128 will be effective for the
first quarter ended December 31, 1997. SFAS No. 128 simplifies the standards
required under current accounting rules for computing earnings per share and
replaces the presentation of primary earnings per share and fully diluted
earnings per share with a presentation of basic earnings per share ("basic
EPS") and diluted earnings per share ("diluted EPS"). Basic EPS excludes
dilution and is determined by dividing income available to common stockholders
by the weighted-average number of common shares outstanding during the period.
Diluted EPS reflects the potential dilution that could occur if securities and
other contracts to issue common stock were exercised or converted into common
stock. Diluted EPS is computed similarly to fully diluted earnings per share
under current accounting rules. The implementation of SFAS No. 128 is not
expected to have a material effect on the Company's earnings per share as
determined under current accounting rules.

4.  EVENT SUBSEQUENT TO THE DATE OF AUDITOR'S REPORT OF INDEPENDENT PUBLIC
    ACCOUNTANTS (UNAUDITED):

     Wholly-owned subsidiaries of Pentacon, Inc. have signed definitive
agreements to acquire by merger or share exchange five companies ("Founding
Companies") to be effective contemporaneously with the Offering. The companies
to be acquired are Alatec Products, Inc., AXS Solutions, Inc., Capitol Bolt &
Supply, Inc., Maumee Industries, Inc., and Sales Systems, Limited The aggregate
consideration that will be paid by Pentacon to acquire the Founding Companies is
approximately $28.7 million in cash and 6,720,000 shares of Common Stock.
   
     In December 1997 Pentacon filed a registration statement on Form S-1 for
the sale of its common stock.

     In January 1998 the Company has reached an agreement in principle with a
bank for a credit facility of $50 million. The bank has also agreed in principle
to use its best efforts to form a syndicate for an additional $25 million credit
facility. The Company intends to use such facilities for working capital, payoff
of indebtedness of the Founding Companies, and acquisitions. The credit
facilities will be subject to customary drawing conditions and the completion of
negotiations with the lender and the execution of appropriate loan
documentation.

     In January 1998 the Company agreed to grant options to purchase 50,000
shares of Common Stock at the public offering price.

Alatec Products, Inc.
Chatsworth, California

     We have audited the accompanying consolidated balance sheet of Alatec
Products, Inc., as of December 31, 1996, and the related statements of income,
stockholders' equity and cash flows for the year then ended. 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 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 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 audit provides a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Alatec
Products, Inc., as of December 31, 1996, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.

                                                         McGLADREY & PULLEN, LLP

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1997

1.  DESCRIPTION OF THE BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

  DESCRIPTION OF THE BUSINESS

     Alatec Products, Inc. (the "Company") is a wholesale distributor of
industrial and aerospace fasteners throughout the United States, Canada, Europe,
South America, and the Far East. Sales to the aerospace and defense industries
represent a significant portion of the Company's total annual sales. The
Company's corporate headquarters are based in Chatsworth, California, and it has
regional sales offices in six states.

  PRINCIPLES OF CONSOLIDATION

     The financial statements include the accounts of the Company's wholly owned
subsidiaries, Trace Alatec Supply Company, Inc.; Alatec Race, Inc.; Alatec
Fastener and Component Group, Inc.; Alatec Cable Harness and Assembly Division,
Inc.; and Alatec International Sales, Inc., a foreign international sales
corporation. All significant intercompany accounts and transactions have been
eliminated.

  CONCENTRATIONS OF CREDIT RISK

     The Company distributes industrial and aerospace fasteners to manufacturers
in a wide variety of industries including the aerospace and defense industries.
Credit is extended based on an evaluation of the customer's financial condition
and collateral is typically not required. Credit losses are provided for in the
financial statements through a charge to operations. Credit losses have been
consistently within management's expectations. Provisions for bad debts and
accounts receivable write-offs have not been significant.

     The Company maintains its cash in bank deposit accounts which, at times,
may exceed federally insured limits. The Company has not experienced any losses
in such accounts. The Company believes it is not exposed to any significant
credit risk on cash maintained in bank deposit accounts.

  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
accompanying notes. Actual results could differ from those estimates.

  INVENTORIES

     Inventories consist primarily of industrial and aerospace fasteners and
related hardware held for sale and are valued at the lower of cost (first-in,
first-out method) or market.

  PROPERTY UNDER CAPITAL LEASES, LEASEHOLD IMPROVEMENTS, AND EQUIPMENT

     Leasehold improvements, buildings acquired under capital leases, and
equipment are recorded at cost. Depreciation is computed using straight-line and
primarily accelerated methods over useful lives ranging from 5 to 20 years.
Leasehold improvements and buildings acquired under capital leases are amortized
over the lesser of the life of the lease or the life of the improvements.

     The amortization expense on assets acquired under capital leases is
included with depreciation expense on owned assets.

  CASH EQUIVALENTS

     For purposes of reporting cash flows, the Company considers all highly
liquid debt instruments purchased with a maturity of three months or less to be
cash equivalents.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of accounts receivable, prepaid expenses, and accounts
payable approximate fair values due to the short-term maturities of these
instruments. The carrying value of the Company's debt facilities and capital
lease agreements approximates fair value because the rates on such facilities
are

                             ALATEC PRODUCTS, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

variable, based on current market, or are at fixed rates currently available to
the Company. The rate of the subordinated note payable to stockholder (discussed
in Note 4 and Note 7) is less than the market rate currently available to the
company, however, the difference between the carrying value of this note and the
fair value is not significant.

  NET SALES RECOGNITION

     Net sales are recognized upon shipment of the product to the customer.
Adjustments to arrive at net sales are primarily allowances for discounts and
returns.

  EXPORT SALES

     The Company recorded export sales of $8,847,000, $8,875,000, and $9,434,000
in the years ended December 31, 1995 and 1996 and the period from January 1,
1997 through September 30, 1997, respectively. The Company has export sales
through its foreign sales corporation to Canada, Europe, South America, and the
Far East of which no country or region is individually significant.

  ACCOUNTING FOR LONG-LIVED ASSETS

     In March 1995, the FASB issued Statement No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed of,
which requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. Statement No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company adopted Statement No.
121 in the first quarter of 1996 and the effect of adoption had no impact on the
financial statements.

  INCOME TAXES

     Income taxes have been provided using the liability method in accordance
with FASB Statement No. 109, ACCOUNTING FOR INCOME TAXES. Under this method,
deferred tax assets and liabilities are determined based on differences between
the financial reporting and tax bases of assets and liabilities and are measured
using the enacted tax rates and laws that will be in effect when the differences
are expected to reverse.

  FISCAL YEAR

     In 1997, the Company changed its fiscal year end from December 31 to
September 30.

2.  PROPERTY AND EQUIPMENT

     Property under capital leases, leasehold improvements, and equipment
consist of:

3.  REVOLVING LINE OF CREDIT

     The revolving line of credit represents borrowings under a $13.3 million
line of credit with a bank. This facility expires in June 1999. At September 30,
1997, unused credit available under this facility was $3,000,000. The Company
has classified all borrowings outstanding under its line of credit as a
long-term liability as it intends to maintain borrowings of at least $9.5
million during 1998. The Company may borrow amounts against 80% of eligible
trade receivables and 50% of eligible inventory, up to $7,000,000. The note
provides for interest at the prime rate (8.5% at September 30, 1997) and is
collateralized by inventory, accounts receivable, equipment and the personal
guarantee of a stockholder. The credit agreement also provides for standby
letters of credit of up to $100,000. At September 30, 1997, there were no
amounts outstanding on the letters of credit. The credit agreement contains
certain restrictive financial covenants including, but not limited to, minimum
working capital requirements and dividend restrictions. As of September 30,
1997, the Company was in compliance with the financial covenants. However, at
September 30, 1997, the Company was not in compliance with certain nonfinancial
covenants relating to providing information and notice of defined transactions
and events to the bank. The bank has provided a written waiver for these
covenant violations and management believes that the Company will be in
compliance with these covenants in future periods.

4.  LONG-TERM DEBT

     Long-term debt consisted of the following:

                                           DECEMBER 31,    SEPTEMBER 30,

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

     As discussed in Note 7, the $776,000 note payable to a stockholder was
cancelled in exchange for 45 shares (pre stock-split) of common stock.

5.  LEASE COMMITMENTS

     The Company leases a portion of its facilities, equipment, and vehicles
under noncancelable capital and operating lease agreements. In April 1992, the
Company entered into a capital lease with a stockholder for its Chatsworth
facilities with an original cost of $1,637,000. Monthly installments, subject to
Consumer Price Index adjustments and including interest at 11.6%, are required
through March 2012. Additionally, the Company leases a smaller facility from the
stockholder under an operating lease.

     Future minimum lease payments under the capital and operating leases,
together with the present value of the net minimum lease payments, as of
September 30, 1997 are as follows:

     Total rental and interest expense charged to operations for the nine months
ended September 30, 1997 and the years ended December 31, 1996 and 1995 was
approximately $640,000, $778,000, and $697,000, respectively, including amounts
to related parties of $451,000, $359,000, and $322,000, respectively.

6.  401(K) PLAN

     The Company has a defined contribution 401(k) plan (the "Plan") for
substantially all of the Company's full-time employees. The Company may make
discretionary contributions and, in addition, may match participants'
contributions. The Company contributed $80,000, $99,000, and $80,000 in matching
contributions to the plan for the nine months ended September 30, 1997 and the
years ended December 31,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

1996 and 1995, respectively. Additionally, in 1997, the Board of Directors
approved a $300,000 discretionary contribution to the Plan. Accordingly, the
contribution was accrued and expensed as of September 30, 1997.

7.  RELATED-PARTY TRANSACTIONS

  EQUITY TRANSACTIONS
   
     At December 31, 1996, the Company was a closely held corporation and all of
the outstanding common stock was owned by immediate family members. During May
1997, certain equity transactions occurred simultaneously. The Company issued 45
shares (pre stock-split) of common stock in exchange for the cancellation of a
stockholder note payable of $776,000. Simultaneously, the Company purchased as
treasury stock 51.29 shares (pre stock split) of common stock representing all
of the shares of common stock held by one of the family members in exchange for
a note payable in the original amount of $2,690,000. The terms of these notes
payable are described below.
    
  NOTES PAYABLE AND RECEIVABLE

     As discussed above, the Company had a 9%, $776,000 note payable to a
stockholder at December 31, 1996. At September 30, 1997, the Company had a
5.64%, $2,687,000 note payable to a former stockholder and current Director, due
November 2024. The note is subordinated to all senior bank debt and is
guaranteed by the President and sole remaining stockholder of the Company. The
note contains provisions that upon the death of the former stockholder, the note
will be terminated and the related debt will be cancelled. During the years
ended December 31, 1995 and 1996 and the nine months ended September 30, 1997,
interest expense of $70,000, $69,000, and $50,000, respectively, was incurred on
these notes.

     In addition, the Company has a non-interest-bearing receivable from a
stockholder of $9,000 as of December 31, 1996 and accrued rents and interest due
to a stockholder of $88,000 as of December 31, 1996. These balances are included
in receivables and other accrued expenses, respectively.

  DEBT GUARANTEE

     The U.S. Small Business Administration ("SBA") has issued a Secured
Business Disaster Loan to a related party for earthquake repairs and
improvements to the Chatsworth facility, which is owned by a stockholder and
leased to the Company. The Company is identified as a co-borrower; however, the
Company has reflected this as a contingent liability similar to a debt
guarantee. The remaining balance on the SBA loan was $1,255,231 and $1,217,000
at December 31, 1996 at September 30, 1997, respectively. The debt matures in
August 2024. No amount of this debt is recorded in the accompanying financial
statements.

  RELATED PARTY PURCHASES

     The Company purchased approximately $1,100,000, $1,386,000, and $1,100,000
in 1995, 1996, and during the period from January 1, 1997 through September 30,
1997, respectively, from a supplier which is 50 percent owned by the principal
stockholder. Additionally, the Company owed $136,000, $209,000, and $154,000 for
the respective periods related to goods purchased for resale classified as
accounts payable in the balance sheet.

8.  CONTINGENCIES

  INCOME TAX EXAMINATION

     The Company's federal income tax returns for the year ended January 31,
1995 are currently being examined by the Internal Revenue Service (the "IRS").
No notices of deficiency have been issued. The Internal Revenue Service has
proposed the capitalization of certain repairs to the Company's Chatsworth
facilities, which sustained earthquake damage, rather than to treat them as
deductible expenses in the year

                                      F-27
<PAGE>
                             ALATEC PRODUCTS, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

incurred, capitalization of freight costs and adjustments for certain other
nondeductible accrued expenses. The Company has recorded an adjustment of
approximately $120,000 for these known deficiencies as a result of the
examination. $116,000 of this adjustment is reflected in the 1996 tax provision
and approximately $4,000 in the 1997 tax provision. The Company has reached an
understanding that resolves all open issues on the audit; however, this
understanding is subject to final IRS approval. There can be no assurance that
there will be no additional assessments; however, management believes that any
additional assessment would not be material.
   
     During 1997, the Company detected that it had erroneously omitted certain
amounts of inventory from its financial statements for federal and state income
tax purposes for tax years ending December 31, 1995 and 1996. The Company
anticipates filing amended returns for 1996 and certain prior periods and has
accrued the tax liability and related interest totaling approximately $2,568,000
and $2,225,000 in 1997 and 1996, respectively. No underpayment or late payment
penalties have been accrued in the financial statements based on preliminary
discussions with the IRS indicating that no penalties would be assessed. If
assessed, these penalties could be as much as $850,000. Based on management's
discussion with the IRS, it is their opinion that no significant penalties will
be assessed, and management believes it will be successful in settling this
issue with the Internal Revenue Service and state taxing authorities within the
amounts accrued in the financial statements.

     Components of income tax expense are as follows:

                                                                  JANUARY 1,

Pentacon, Inc. and
The Board of Directors
AXS Solutions, Inc.

     We have audited the accompanying balance sheets of AXS Solutions, Inc. as
of December 31, 1996 and September 30, 1997, and the related statements of
income, shareholders' equity, and cash flows for each of the two years in the
period ended December 31, 1996 and the period from January 1, 1997 through
September 30, 1997. 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 AXS Solutions, Inc. at
December 31, 1996 and September 30, 1997, and the results of its operations and
its cash flows for each of the two years in the period ended December 31, 1996
and the period from January 1, 1997 through September 30, 1997, in conformity
with generally accepted accounting principles.

1.  BUSINESS AND BASIS OF PRESENTATION

     AXS Solutions, Inc. ("AXS Solutions") is a wholesaler and distributor of
threaded fastener products, including nuts, bolts, washers and screws, to
customers located predominantly in the Northeastern and Midwestern United
States. AXS Solutions was incorporated on August 19, 1996. On August 31, 1996,
the shareholders of Champion Bolt Corp. ("Champion Bolt") surrendered all of
their shares of common stock of Champion Bolt in exchange for shares of both
voting and non-voting common stock of AXS Solutions. There was deemed to be no
change of control as a result of this transaction. Subsequently, the Champion
Bolt shares were cancelled for no consideration.

     AXS Solutions then acquired all of the common stock of Hoyt Fastener Corp.
("Hoyt Fastener") in exchange for shares of both voting and non-voting common
stock of AXS Solutions. This acquisition was accounted for using the purchase
method of accounting and, accordingly, the purchase price (approximately $5.2
million based on an independent valuation) has been allocated to the assets
purchased and the liabilities assumed based upon the fair values at the date of
acquisition. Goodwill of approximately $3,145,000 was recorded as a result of
this acquisition. The Hoyt Fastener shares were also subsequently cancelled. The
operating results of the acquired business, Hoyt Fastener, have been included in
the income statement from the date of the acquisition.

     The financial statements presented herein represent the operating results
of Champion Bolt for the period from January 1, 1995 through August 31, 1996 and
the operating results of AXS Solutions for the period from September 1, 1996
through September 30, 1997. The reference to "Company" in these financial
statements includes such presentation.

     The following unaudited results of operations have been prepared assuming
the acquisition had occurred on January 1, 1995. These results are not
necessarily indicative of results of future operations nor of results that would
have occurred had the acquisitions been consummated as of January 1, 1995:

                                               1995            1996

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  INVENTORY

     Inventory consists of product held for resale and is stated at the lower of
cost or market, with cost determined using the first-in, first-out (FIFO) method
of inventory valuation.

  PROPERTY AND EQUIPMENT

     Property and equipment is stated at cost. Depreciation is provided on the
straight-line method over the respective estimated useful lives of the assets
ranging from 5 to 40 years. The capital lease is amortized over the estimated
useful life of the asset or lease term, as appropriate, using the straight-line
method. Depreciation expense includes amortization of assets recorded under the
capital lease. Accumulated amortization for the capital lease was $35,288 and
$114,686 at December 31, 1996 and September 30, 1997, respectively.

  NON-COMPETE AGREEMENT

     The cost of the non-compete agreement is being amortized over 10 years, the
term of the covenant. Accumulated amortization amounted to $519,495 and $598,740
at December 31, 1996 and September 30, 1997, respectively.

                              AXS SOLUTIONS, INC.
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  GOODWILL

     Goodwill is being amortized over a period of 40 years. Accumulated
amortization amounted to $26,713 and $86,817 at December 31, 1996 and September
30, 1997, respectively.

  CASH EQUIVALENTS

     The Company considers all investments purchased with a maturity of three
months or less to be cash equivalents.

  INCOME TAXES

     The Company is a Subchapter S Corporation and as such, its stockholders are
taxed directly on all income.

  NET SALES RECOGNITION

     Net sales are recognized upon shipment of the product to the customer.
Adjustments to arrive at net sales are primarily related to discounts.

  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
accompanying notes. Actual results could differ from those estimates.

  CONCENTRATION OF CREDIT RISK

     The Company performs credit evaluations of its customers and generally does
not require collateral. The Company maintains an allowance for doubtful accounts
based upon the expected collectibility of all accounts receivable. One customer
accounted for approximately 55%, 50% and 45% of revenues for 1995, 1996 and the
period from January 1, 1997 through September 30, 1997, respectively. At
December 31, 1996 and September 30, 1997, accounts receivable balances related
to this customer represented approximately 34% and 28% of total accounts
receivable, respectively.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of accounts receivable, prepaid expenses, and accounts
payable approximate fair values due to the short-term maturities of these
instruments. The carrying value of the Company's debt facilities and capital
lease agreements approximate fair value because the rates on such facilities are
variable, based on current market or are at fixed rates currently available to
the Company.

  ACCOUNTING FOR LONG-LIVED ASSETS

     In March 1995, the FASB issued Statement No. 121, ACCOUNTING FOR THE
IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF,
which requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. Statement No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company adopted Statement No.
121 in the first quarter of 1996 and the effect of adoption had no impact on the
financial statements.

                                          ==========
   
     The Company has a demand note payable with a bank up to a maximum of
$3,000,000, with interest payable at the prime rate. The demand note payable is
guaranteed by separate balances with this bank of two of the four voting
shareholders of the Company. At December 31, 1996, the Company had exceeded its
borrowing limit by $300,000 as a result of making a year end tax payment. The
excess borrowings were repaid in early January 1997.
    
     In addition, at September 30, 1997 the Company has an available letter of
credit of approximately $50,000 for inventory purchases.

4.  LEASES

     The Company is obligated under a noncancelable lease with a related party
which expires August 31, 2006. Under this lease, the lessor of warehouse and

5.  EMPLOYEE BENEFIT PLANS

     The Company maintains a non-contributory defined-benefit pension plan
covering all of its employees. The benefits are based on years of service and
the employee's compensation during the entire period of employment. The
Company's funding policy is to contribute annually the amount necessary to meet
minimum funding standards of ERISA. Plan assets are invested primarily in
corporate stocks and government securities.

     The following table sets forth the plan's funded status and amounts
recognized in the Company's respective balance sheets:

     The Company also sponsors two defined contribution plans under Section
401(k) of the Code. The first plan covers all eligible Pennsylvania employees of
the Company, and participants are permitted to make elective pretax deferrals up
to 20% of their compensation. Under this plan, the Company has the ability to
make additional discretionary contributions allocated to the participants as a
flat dollar amount or in proportion to their compensation. The second plan
covers all eligible Illinois employees of the Company, and participants are
permitted to make elective pretax deferrals up to a set percentage of their
compensation (to be determined by the Company) as well as post-tax contributions
subject to IRS limitations. Under this plan, the Company has the ability to make
additional discretionary contributions allocated to the participants in
proportion to their compensation. The Company contributed approximately $0,
$19,200, and $9,600 to these plans for 1995, 1996, and the period January 1,
1997 through September 30, 1997, respectively.

6.  RELATED PARTIES

     The Company has a receivable from a shareholder which represents an excess
S Corporation distribution which is expected to be paid back to the Company by
December 31, 1997.

     The shareholder distribution payable is a result of the Company declaring a
dividend in 1997 in the amount equal to the total undistributed S Corporation
accumulated earnings of the Company as of September 30, 1997.

7.  COMMITMENTS AND CONTINGENCIES

     Under terms of the Shareholders Agreement, upon the death or withdrawal of
a shareholder, the Company has the option to purchase that shareholder's
non-voting shares at the purchase price as defined in the Shareholders
Agreement. The remaining shareholders then have the option to purchase the
remaining decedent/withdrawn shareholder's non-voting shares at the purchase
price as defined in the Shareholders Agreement. If any of the decedent/withdrawn
shareholder's non-voting shares remain, the decedent/withdrawn shareholder's
estate has the option to require the Company to redeem such non-voting shares at
the purchase price as defined in the Shareholders Agreement.

definitive agreement with a wholly-owned subsidiary of Pentacon, Inc. which
among other things calls for the merger of the Company with the Pentacon, Inc.

Board of Directors
Maumee Industries, Inc.

     We have audited the accompanying balance sheets of Maumee Industries, Inc.
(the "Company"), as of December 31, 1996 and September 30, 1997, and the
related statements of operations, stockholders' deficit, and cash flows for each
of the two years in the period ended December 31, 1996 and the period from
January 1, 1997 through September 30, 1997. 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 Maumee Industries, Inc., at
December 31, 1996 and September 30, 1997, and the results of its operations and
its cash flows for each of the two years in the period ended December 31, 1996
and the period from January 1, 1997 through September 30, 1997, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1997

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  ORGANIZATION

     Maumee Industries, Inc. (the "Company") is engaged in the wholesale
distribution of fasteners and nonfastener small parts primarily to
Midwestern-based manufacturers in the automotive industry. During for the years
ended December 31, 1995, and 1996, and period from January 1, 1997 through
September 30, 1997, net sales to two customers approximated $18,000,000,
$23,100,000, and $21,800,000, respectively. In relation to these customers,
approximately $4,300,000 was included in accounts receivable at September 30,
1997.

  NET SALE RECOGNITION

     Net sales are recognized upon shipment of the product to the customer.
Adjustments to arrive at net sales are primarily related to discounts.

  INVENTORIES

     Inventories consist of goods held for resale and are valued at the lower of
cost (first-in, first-out method) or market.

  EQUIPMENT AND LEASEHOLD IMPROVEMENTS

     Equipment and leasehold improvements are stated on the cost basis.
Equipment is depreciated using accelerated depreciation methods based on
estimated useful lives ranging from three to ten years. Leasehold improvements
are amortized using the straight-line method over the lesser of the estimated
useful lives of the assets or the term of the related lease.

  USE OF ESTIMATES

     The preparation of the 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
accompanying notes. Actual results could differ from those estimates.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of accounts receivable, prepaid expenses, and accounts
payable approximate fair value due to the short-term maturities of these
instruments. The carrying value of the Company's debt facilities and capital
lease agreements approximates fair value because the rates on such facilities
are variable, based on current market, or are at fixed rates currently available
to the Company.

  ACCOUNTING FOR LONG-LIVED ASSETS

     In March 1995, the FASB issued Statement No. 121, ACCOUNTING FOR THE
IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF,
which requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. Statement No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company adopted Statement No.
121 in the first quarter of 1996 and the effect of adoption had no impact on the
financial statements.

  INCOME TAXES

     Income taxes have been provided using the liability method in accordance
with FASB Statement No. 109, ACCOUNTING FOR INCOME TAXES.

The plan allows for both employee and Company contributions. The Company
contribution consists of a matching contribution of 50% of employee
contributions, up to 6% of eligible employee compensation.

                         NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1997

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  COMPANY DESCRIPTION

     Sales Systems, Limited (the "Company") is a wholesaler and distributor of
industrial fasteners, primarily to manufacturers in the eastern United States.

  INVENTORIES

     Inventories consist of goods held for resale and are stated at the lower of
cost or market using the first-in, first-out method.

  PROPERTY, PLANT, AND EQUIPMENT

     Property, plant, and equipment are recorded at cost. Depreciation and
amortization expense, including amounts related to capital leases, is calculated
by accelerated methods over the estimated useful lives of the assets, which vary
from three to eight years.

  NET SALES RECOGNITION

     Net sales are recognized upon shipment of the product to the customer.
Adjustments to arrive at net sales are primarily for discounts.

  INCOME TAXES

     Effective January 1, 1995, the Company made an election to be taxed as an S
corporation for federal purposes and for the majority of states in which the
Company operates. Correspondingly, tax liabilities subsequent to this date
related to the Company's ongoing operations will generally be the responsibility
of the individual shareholders.

  STATEMENT OF CASH FLOWS

     Cash paid for interest during the year ended December 31, 1996 and the
period from January 1, 1997 through September 30, 1997 was $106,799 and $95,167,
respectively.

  USE OF ESTIMATES

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

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of accounts receivable, prepaid expenses, and accounts
payable approximate fair values due to the short-term maturities of these
instruments. The carrying value of the Company's debt facilities approximates
fair value because the rates on such facilities are variable, based on current
market, or are at fixed rates currently available to the Company.

  ACCOUNTING FOR LONG-LIVED ASSETS

     In March 1995, the FASB issued Statement No. 121, ACCOUNTING FOR THE
IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF,
which requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. Statement No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company adopted Statement No.
121 in the first quarter of 1996 and the effect of adoption had no impact on the
financial statements.

2.  CONCENTRATION OF CREDIT RISK AND SALES TO LARGEST CUSTOMERS

     Sales to the Company's two largest customers were approximately $9,500,000,
or 60.6% of net sales, for the year ended December 31, 1996. Sales to the
Company's four largest customers were approximately $9,400,000, or 78.7% of net
sales, for the period January 1, 1997 through September 30, 1997.

     The related accounts receivable balances were $442,545 and $538,940 as of
December 31, 1996 and September 30, 1997, respectively.

3.  FINANCING ARRANGEMENTS

  NOTE PAYABLE

     The Company has a $1,250,000 line of credit agreement with a bank. The line
of credit matures on June 1, 1998, subject to automatic renewals thereof on an
annual basis unless a contrary notice is delivered by either party within a
prescribed period. The line of credit is secured by accounts receivable and
inventory, and is guaranteed by the Company's shareholders. The line of credit
bears interest at the New York prime rate (8.5% at September 30, 1997). At
September 30, 1997, there were available amounts of $907,626 to be borrowed
under the line of credit.

     The agreement includes certain restrictive covenants with respect to, among
other matters, distributions paid to shareholders, purchase or redemption of the
Company's stock, mergers or consolidated transactions, asset dispositions, and
the incurrence of additional debt. It also includes additional financial
covenants related to the maintenance of net worth, working capital, and net
income levels along with a limitation on annual capital expenditures. At
September 30, 1997 the Company was in compliance with these covenants.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Subsection (a) of section 145 of the General Corporation Law of the State
of Delaware empowers a corporation to 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 he 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 him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he 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 his conduct was unlawful.

     Subsection (b) of Section 145 empowers a corporation to 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 acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that no indemnification may be made in
respect of any claim, issue or matter as to which such person shall have been
made to be liable to the corporation unless and only to the extent that the
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, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

     Section 145 further provides that to the extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section 145
in the defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection therewith; that indemnification provided for by Section 145
shall not be deemed exclusive of any other rights to which the indemnified party
may be entitled; that indemnification provided for by 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 such person's heirs, executors and administrators; and empowers the
corporation to purchase and maintain insurance on behalf of a director or
officer of the

                                      II-1
<PAGE>
corporation against any liability asserted against him and incurred by him in
any such capacity, or arising out of his status as such whether or not the
corporation would have the power to indemnify him against such liabilities under
Section 145.

     Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a certificate of incorporation may contain a provision eliminating
or limiting the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
provided that such provision shall not eliminate or limit the liability of a
director (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 Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit.

     Article 7 of the Company's Amended and Restated Certificate of
Incorporation states that:

     No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty by such director as a director; provided, however, that this Article 7
shall not eliminate or limit the liability of a director to the extent provided
by applicable law (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 DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. No amendment to or repeal of this Article
Eighth shall apply to, or have any effect on, the liability or alleged liability
of any director of the Corporation for or with respect to any acts or omissions
of such director occurring prior to such amendment or repeal. If the DGCL is
amended to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of a director of the
Corporation shall be eliminated or limited to the fullest extent permitted by
the DGCL, as so amended.

     The Company intends to enter into indemnification agreements with each of
its executive officers and directors.

     In November 1997, Messrs. Grossman and Pugh, each principals in MGCV,
became officers of Alatec in order to assist in, facilitate and expedite the
audit process in connection with the Offering. Alatec and Mr. List, its sole
stockholder, have agreed to indemnify Messrs. Grossman and Pugh against various
claims, damages, costs and expenses which might be incurred by them as officers
of Alatec, including their execution of representation letters to Alatec's
accountants.

     Under Section of the Underwriting Agreement filed as Exhibit 1.1 to this
Registration Statement, the Underwriters have agreed to indemnify, under certain
conditions, the Company, its officers and directors, and persons who control the
Company within the meaning of the Securities Act of 1933, as amended, against
certain liabilities.

ITEM 17.  UNDERTAKINGS

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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

      7.7 NOTIFICATION OF CERTAIN MATTERS BY THE STOCKHOLDER AND THE COMPANY.
The Stockholder and the Company shall give prompt notice to Pentacon of (i) the
occurrence or non-occurrence of any event the occurrence or nonoccurrence of
which would be likely to cause any representation or warranty of the Company or
the Stockholder contained herein to be untrue or inaccurate in any material
respect at or prior to the Closing and (ii) any material failure of any
Stockholder or the Company to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by such person hereunder. Pentacon
and Newco shall give prompt notice to the Company of (i) the occurrence or
non-occurrence of any event the occurrence or non-occurrence of which would be
likely to cause any representation or warranty of Pentacon or Newco contained
herein to be untrue or inaccurate in any material respect at or prior to the
Closing and (ii) any material failure of Pentacon or Newco to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder. The delivery or deemed delivery of any notice pursuant to this
Section 7.7 shall not be deemed to (i) modify the representations or warranties
hereunder of the party delivering such notice, which modification may only be
made pursuant to Section 7.8, (ii) modify the conditions set forth in Sections 8
and 9, or (iii) limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

      If, prior to the Closing Date, the Chief Executive Officer, the Chief
Financial Officer or the General Counsel of Pentacon shall determine that any of
Pentacon, Newco, the Surviving Corporation or the Company has a claim hereunder
for indemnification against any Stockholder(s) (whether or not such claim might
exceed the Indemnification Threshold), then Pentacon shall promptly advise the
affected Stockholder(s), in writing, of such potential claim and provide
information supporting the basis and potential amount of such claim (a
"Potential Claim Notice"). This procedure with respect to Potential Claim
Notices is intended to afford the affected Stockholder(s) notice so that it may
attempt to cure or otherwise address the claim prior to Closing; provided,
however, that (i) this procedure shall not affect or delay Closing and (ii)
neither the failure or delay by Pentacon to give a Potential Claim Notice nor
the information included or omitted from a Potential Claim Notice shall
constitute a waiver of, or shall otherwise adversely affect the right to receive
indemnification for, any such claim paid by Pentacon, Newco, the Surviving
Corporation or the Company hereunder after the Closing Date.

      7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect to
the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the Company that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect with respect to the Company
may be made unless Pentacon and a majority of the Founding Companies other than
the Company consent to such amendment or

                                      -33-
<PAGE>
supplement; and provided further, that no amendment or supplement to a Schedule
prepared by Pentacon or Newco that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect with respect to Pentacon or
Newco may be made unless a majority of the Founding Companies consent to such
amendment or supplement. For all purposes of this Agreement, including without
limitation for purposes of determining whether the conditions set forth in
Sections 8.1 and 9.1 have been fulfilled, the Schedules hereto shall be deemed
to be the Schedules as amended or supplemented pursuant to this Section 7.8. In
the event that one of the Other Founding Companies seeks to amend or supplement
a Schedule pursuant to Section 7.8 of one of the Other Agreements, and such
amendment or supplement constitutes or reflects an event or occurrence that
would have a Material Adverse Effect on such Other Founding Company, Pentacon
shall give the Company written notice promptly after it has knowledge thereof.
If Pentacon and a majority of the Founding Companies consent to such amendment
or supplement, which consent shall have been deemed given by Pentacon or any
Founding Company if no response is received within 24 hours following receipt of
written notice of such amendment or supplement (or sooner if reasonable and if
required by the circumstances under which such consent is requested), but the
Company does not give its consent, the Company may terminate this Agreement
pursuant to Section 12.1(iv) hereof. In the event that the Company seeks to
amend or supplement a Schedule pursuant to this Section 7.8, and Pentacon and a
majority of the Other Founding Companies do not consent to such amendment or
supplement, this Agreement shall be deemed terminated by mutual consent as set
forth in Section 12.1(i) hereof. In the event that Pentacon or Newco seeks to
amend or supplement a Schedule pursuant to this Section 7.8 and a majority of
the Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. No party to this Agreement shall be liable to any other party if
this Agreement shall be terminated pursuant to the provisions of this Section
7.8. No amendment of or supplement to a Schedule shall be made later than 24
hours prior to the anticipated effectiveness of the Registration Statement.

act that would jeopardize the tax-free status of the organization, including
without limitation:

            (a) the retirement or reacquisition, directly or indirectly, of all

      before the Consummation Date, and shall permit Pentacon to review all such
      Returns prior to such filings. Unless the Company is a C corporation, the
      Stockholder shall pay or cause to be paid all Tax liabilities (in excess
      of all amounts already paid with respect thereto or properly accrued or
      reserved with respect thereto on the Financial Statements) shown by such
      Returns to be due.

      filing any Return, amended Return or claim for refund, determining a
      liability for Taxes or a right to refund of Taxes or in conducting any

      information shall include providing copies, at the expense of the
      requesting party, of all relevant portions of relevant Returns, together
      with relevant accompanying schedules and relevant work papers, relevant
      documents relating to rulings or other determinations by Taxing
      Authorities and relevant records concerning the ownership and Tax basis of
      property, which such party may possess. Each party shall make its
      employees reasonably available on a mutually convenient basis at its cost
      to provide explanation of any documents or information so provided.

      pursuant to this Agreement shall bear all costs of filing such Returns.

      Treasury Regulations promulgated under the Code, and treat the transaction
      as a tax-free contribution under Section 351(a) of the Code subject to
      gain, if any, recognized on the receipt of cash or other property under
      Section 351(b) of the Code subject to gain, if any, recognized on the
      receipt of cash or other property under Section 351(b) of the Code.

      10.3 DIRECTORS. The persons named in the Draft Registration Statement
shall be appointed as directors and elected as officers of Pentacon, as and to

11.   INDEMNIFICATION

      The Stockholder, Pentacon and Newco each make the following covenants that
are applicable to them, respectively:

      11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDER. Subject to the
limitations set forth in Section 11.5, the Stockholder covenants and agrees that
he will indemnify, defend, protect and hold harmless Pentacon, Newco, the
Company and the Surviving Corporation at all times, from and after the date of
this Agreement until the Expiration Date (provided that for purposes of Section
11.1(iii) below, the Expiration Date shall be the date on which the applicable
statute of limitations expires), from and against all claims, damages, actions,
suits, proceedings, demands, assessments, adjustments, costs and expenses
(including specifically, but without limitation, reasonable attorneys' fees and
expenses of investigation) incurred by Pentacon, Newco, the Company or the
Surviving Corporation as a result of or arising from (i) any breach of the
representations and warranties of the Stockholder or the Company set forth
herein or on the definitive, final schedules or certificates

                                      -42-
<PAGE>
delivered by them in connection herewith, (ii) any breach of any agreement on
the part of the Stockholder or, prior to Closing, the Company under this
Agreement, or (iii) any liability under the 1933 Act, the 1934 Act or other
Federal or state law or regulation, at common law or otherwise, arising out of
or based upon any untrue statement or alleged untrue statement of a material
fact relating to the Company or the Stockholder, and provided in writing to
Pentacon or its counsel by the Company or the Stockholder for inclusion in the
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to the
Company or the Stockholder required to be stated therein or necessary to make
the statements therein not misleading, provided, however, that such indemnity
shall not inure to the benefit of Pentacon, Newco, the Company or the Surviving
Corporation to the extent that such untrue statement (or alleged untrue
statement) was made in, or omission (or alleged omission) occurred in, any
preliminary prospectus and the Stockholder provided, in writing, corrected
information to Pentacon counsel and to Pentacon for inclusion in the final
prospectus, and such information was not so included or properly delivered, and
provided further, that no Stockholder shall be liable for any indemnification
obligation pursuant to this Section 11.1(iii) to the extent attributable to a
breach of any representation, warranty or agreement made herein individually by
any other Stockholder.

      Pentacon and Newco acknowledge and agree that other than the
representations and warranties of Company or Stockholder specifically contained
in this Agreement, there are no representations or warranties of Company or
Stockholder, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

      Pentacon, Newco and the Company further acknowledge and agree that, should
the Closing occur, their sole and exclusive remedy with respect to any and all
claims relating to this Agreement and the transactions contemplated in this
Agreement, shall be pursuant to the indemnification provisions set forth in this
Section 11.1. Pentacon, Newco and the Company hereby waive, from and after the
Closing, to the fullest extent permitted under applicable law, any and all
rights, claims and causes of action they or any indemnified person may have
against the Company or any Stockholder relating to this Agreement or the
transactions contemplated hereby arising under or based upon any federal, state,
local or foreign statute, law, rule, regulation or otherwise (and other than
pursuant to the terms of this Agreement).

      11.2 INDEMNIFICATION BY PENTACON. Subject to the limitations set forth in
Section 11.5, Pentacon covenants and agrees that it will indemnify, defend,
protect and hold harmless the Stockholder at all times from and after the date
of this Agreement until the Expiration Date, from and against all claims,
damages, actions, suits, proceedings, demands, assessments, adjustments, costs
and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by the Stockholder as a
result of or arising from (i) any breach by Pentacon or Newco of their
representations and warranties set forth herein or on the definitive, final
schedules or certificates attached delivered by them pursuant hereto, (ii) any
breach of any agreement on the part of Pentacon or Newco under this Agreement or
any other agreement delivered pursuant hereto, (iii) any liabilities which the
Stockholder may incur due to Pentacon's or Newco's

                                      -43-
<PAGE>
or the Surviving Corporation's failure to pay, perform or discharge when due any
of the liabilities and obligations of the Company for which Pentacon, Newco or
the Surviving Corporation is responsible pursuant to this Agreement (except to
the extent that Pentacon or Newco has bona fide claims hereunder against the
Stockholder by reason of such liabilities); or (iv) any liability under the 1933
Act, the 1934 Act or other Federal or state law or regulation, at common law or
otherwise, arising out of or based upon any untrue statement or alleged untrue
statement of a material fact relating to Pentacon, Newco or any of the Other
Founding Companies contained in any preliminary prospectus, the Registration
Statement or any prospectus forming a part thereof, or any amendment thereof or
supplement thereto, or arising out of or based upon any omission or alleged
omission to state therein a material fact relating to Pentacon or Newco or any
of the Other Founding Companies required to be stated therein or necessary to
make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Subject to the limitations set forth in Section
11.5, promptly after any party hereto (hereinafter the "Indemnified Party") has
received notice of or has actual knowledge of any claim by a Person (including a
governmental agency) not a party to this Agreement ("Third Person"), or the
commencement of any action or proceeding by a Third Person, with respect to
which the Indemnified Person would be entitled to receive indemnification
pursuant to Section 11, the Indemnified Party shall, as a condition precedent to
a claim with respect thereto being made against any party obligated to provide
indemnification pursuant to Section 11.1 or 11.2 hereof (hereinafter the
"Indemnifying Party"), give the Indemnifying Party written notice of such claim
or the commencement of such action or proceeding. Such notice shall state the
nature and the basis of such claim and a reasonable estimate of the amount
thereof. The Indemnifying Party shall have the right to defend and settle, at
its own expense and by its own counsel, any such matter so long as the
Indemnifying Party pursues the same in good faith and diligently, provided that
the Indemnifying Party shall not settle any criminal proceeding without the
written consent of the Indemnified Party. If the Indemnifying Party undertakes
to defend or settle, it shall promptly notify the Indemnified Party of its
intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party, Indemnified
Party shall have the right to participate in such matter through counsel of its
own choosing and Indemnifying Party will reimburse the Indemnified Party for the
reasonable expenses of its counsel. After the Indemnifying Party has notified
the Indemnified Party of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnifying Party diligently pursues
such defense through appropriate proceedings, the Indemnifying Party shall not
be liable for any additional legal expenses incurred by the Indemnified Party in
connection with any defense or settlement of such asserted liability, except (i)
as set forth in the preceding sentence and (ii) to the extent such participation
is requested by the Indemnifying Party, in which event the Indemnified Party
shall be reimbursed by the Indemnifying Party for reasonable additional legal
expenses and out-of-pocket expenses. If the Indemnifying Party desires

                                      -44-
<PAGE>
to accept a final and complete settlement of any such Third Person claim and the
Indemnified Party refuses to consent to such settlement, then the Indemnifying
Party's liability under this Section with respect to such Third Person claim
shall be limited to the amount so offered in settlement by said Third Person.
Upon agreement as to such settlement between said Third Person and the
Indemnifying Party, the Indemnifying Party shall, in exchange for a complete
release from the Indemnified Party, promptly pay to the Indemnified Party the
amount agreed to in such settlement and the Indemnified Party shall, from that
moment on, bear full responsibility for any additional costs of defense which it
subsequently incurs with respect to such claim and all additional costs of
settlement or judgment. If the Indemnifying Party does not undertake to defend
such matter to which the Indemnified Party is entitled to indemnification
hereunder, or fails diligently to pursue such defense, the Indemnified Party may
undertake such defense through counsel of its choice, at the cost and expense of
the Indemnifying Party, and the Indemnified Party may settle such matter, and
the Indemnifying Party shall reimburse the Indemnified Party for the amount paid
in such settlement and any other liabilities or expenses incurred by the
Indemnified Party in connection therewith, provided, however, that under no
circumstances shall the Indemnified Party settle any Third Person claim without
the written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld or delayed. All settlements hereunder shall effect a
complete release of the Indemnified Party, unless the Indemnified Party
otherwise agrees in writing. The parties hereto will make appropriate
adjustments for insurance proceeds in determining the amount of any
indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. (a) The indemnification provided for in this
Section 11 shall (except as prohibited by ERISA) be the exclusive remedy in any
action seeking damages or any other form of monetary relief brought by any party
to this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case pursuant to Section
14.3 or otherwise, to seek injunctive or other equitable relief (except for
rescission which shall not be available) for a breach or threatened breach of
this Agreement. Any indemnity payment under this Section 11 shall, to the extent
permitted by law and if not adverse to the Company or Pentacon, be treated as a
recomputation of or an adjustment to the exchange consideration for tax purposes
unless a final determination (which shall include the execution of a Form 870-AD
or successor form) with respect to the indemnified party or any of its affiliate
causes any such payment not to be treated as an adjustment to the exchange
consideration for U.S. Federal Income Tax purposes.

            (b) Nothing in this Article 11 shall restrict the Stockholder from
subrogation or seeking reimbursement from third parties other than the Company.

      11.5 LIMITATIONS ON INDEMNIFICATION. Pentacon, Newco, the Surviving
Corporation and the other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall not assert any claim for indemnification hereunder against
the Stockholder after the applicable Expiration Date and in no event until such
time as, and solely to the extent that, the aggregate of all claims which such
persons may have against the Stockholder shall exceed the greater of 1% of the
value of the total consideration (including stock and cash) received by the
Stockholder from the Merger or $100,000

                                      -45-
<PAGE>
(the "Indemnification Threshold"), and then only to the extent of the excess
over the Indemnification Threshold. Stockholder shall not assert any claim for
indemnification hereunder against Pentacon or Newco after the applicable
Expiration Date and in no event until such time as, and solely to the extent
that, the aggregate of all claims which Stockholder may have against Pentacon or
Newco shall exceed the Indemnification Threshold, and then only to the extent of
the excess over the Indemnification Threshold.

      The Indemnification Threshold and the other limitations contained in this
Section 11.5 shall not be applicable to any breach of covenants made by the
Stockholders in this Agreement which require an action or inaction by such
Stockholders from and after the Closing Date (i.e., Article 10, Article 11,
Article 13, Article 14, Article 17 and Sections 18.1 and 18.6). No person shall
be entitled to indemnification under this Section 11 if, and only to the extent
that such person's claim for indemnification is directly related to a breach by
such person of any representation, warranty, covenant or other agreement set
forth in this Agreement.

      The pursuit by Pentacon, the Surviving Corporation, Newco or the Company,
of any claim for indemnification hereunder against a Stockholder shall require a
majority vote of the board of directors of Pentacon excluding for the purposes
of such acts any directors who was previously a stockholder of the Company or is
a representative of the stockholders of the Company as existing prior to the
closing of the transactions contemplated at this Agreement.

      Notwithstanding any other term of this Agreement, no Stockholder shall be
liable (in the aggregate from time to time taking into account all
indemnification payments made hereunder) under this Section 11 (i) for any
amount which is less than or equal to the Indemnification Threshold (and then
only to the extent of the excess over the Indemnification Threshold) or (ii) for
any amount which exceeds the amount of proceeds (including cash and stock)
received by such Stockholder in connection with the Merger. Each Stockholder
shall have the option of satisfying his indemnity obligation in cash and/or by
returning shares of Pentacon Stock to Pentacon or any other Indemnified Party
which shall, to the extent permitted by law and if not adverse to the Company or
Pentacon, be considered as a recomputation of the purchase consideration. For
purposes of calculating the value of the Pentacon Stock received by a
Stockholder and satisfying any indemnity claim by returning or transferring
Pentacon Stock, Pentacon Stock shall be valued at its initial public offering
price as set forth in the Registration Statement.

      Notwithstanding any of the foregoing provisions of this Section 11 that
might be read to the contrary, it is the agreement of the parties that the
Indemnification Threshold be given full effect under all circumstances.
Accordingly, insofar as any of the foregoing provisions of this Section 11 may
hold harmless an Indemnified Party before the Indemnification Threshold has been
met, then Pentacon and the Stockholder shall cooperate in good faith to
establish an equitable procedure pursuant to which Pentacon reimburses or causes
the reimbursement to the affected Stockholder(s) of all expenditures and
payments by Stockholder that are intended to be absorbed and borne by any
Indemnified Parties as a result of the prior application of the Indemnification
Threshold or otherwise takes such action as may be reasonably necessary to give
effect to the Indemnification Threshold.

      11.6  SPECIAL INDEMNITY ISSUES.

            (a) Stockholder covenants and agrees that he will pay, indemnify,
defend, protect and hold harmless Pentacon, Newco, the Company and the Surviving
Corporation at all times, from and after the date of this Agreement, from the
following: (i) any interest payable, or alleged to be payable, by any such
indemnified parties to the Internal Revenue Service or any other federal, state
or other governmental or regulatory authority for the period of October 1, 1996
through September 30, 1997 as a result of or in connection with the filing of
amended and restated tax returns for 1995 and 1996 to reflect the addition of
certain inventories which were not included in such Tax Returns, (ii) any
penalties, assessments, charges or other punitive amounts imposed by the
Internal Revenue Service upon any of the indemnified parties as a result of or
in connection with the filing of amended and restated tax returns for 1995 and
1996 to reflect the addition of certain inventories which were not included in
such financial reports, (iii) any Taxes or Tax liability incurred by any of the
indemnified parties as a result of or in connection with any expenses of the
Company being reclassified by the Internal Revenue Service or other federal,
state or other governmental or regulatory authority as a dividend or
constructive dividend to Don List or any of his affiliates for tax years 1995
and 1996, and (iv) any damages, costs and expenses (including, without
limitation, reasonable attorneys' fees and expenses of investigation) arising
out of or in connection with the matters set forth in subsections (i) through
(iii) above. The indemnification obligations contained in this Section 11.6
shall not be subject to the limitations contained in Section 11.5.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION. This Agreement may be terminated at any time prior to
the Consummation Date solely:

            (i)   by mutual consent of the boards of directors of Pentacon and 
      the Company;

            (ii) by the Stockholder or the Company (acting through its board of
      directors), on the one hand, or by Pentacon (acting through its board of
      directors), on the other hand, if the transactions contemplated by this
      Agreement to take place at the Closing shall not have been consummated by
      February 28, 1998, unless the failure of such transactions to be
      consummated is due to the willful failure of the party seeking to
      terminate this Agreement to perform any of its obligations under this
      Agreement to the extent required to be performed by it prior to or on the
      Consummation Date;

            (iii) by the Stockholder or Company, on the one hand, or by
      Pentacon, on the other hand, if a material breach or default shall be made
      by the other party in the observance or in the due and timely performance
      of any of the covenants or agreements contained herein, and the curing of
      such default shall not have been made on or before the Consummation Date
      or by the Stockholder or the Company, if the conditions set forth in
      Section 8 hereof have not been satisfied or waived as of the Closing Date
      or the Consummation Date, as

                                      -47-
<PAGE>
      applicable, or by Pentacon, if the conditions set forth in Section 9
      hereof have not been satisfied or waived as of the Closing Date or the
      Consummation Date, as applicable;

            (iv) pursuant to Section 7.8 hereof;

            (v) pursuant to the termination provisions contained in Section 4
      hereof; or

            (vi) pursuant to the other express terms of this Agreement.

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The Stockholder will not, for a period of five
(5) years following the Consummation Date, for any reason whatsoever, directly
or indirectly, for themselves or on behalf of or in conjunction with any other
person, persons, company, partnership, corporation or business of whatever
nature:

            (i) except as disclosed in Schedule 13.1, engage, as an officer,
      director, shareholder, owner, partner, joint venturer, or in a managerial
      capacity, whether as an employee, independent contractor, consultant or
      advisor, or as a sales representative, in any fastener business or
      operation or related services business in direct competition with Pentacon
      or any of the subsidiaries thereof, within 100 miles of where the Company
      or any of its subsidiaries conducted business prior to the effectiveness
      of the Merger (the "Territory");

            (ii) except with the prior written consent of Pentacon, call upon
      any person who is, at that time, within the Territory, an employee of
      Pentacon or any subsidiary thereof for the purpose or with the intent of
      enticing such employee away from or out of the employ of Pentacon or any
      subsidiary thereof;

            (iii) call upon any person or entity which is, at that time, or
      which has been, within one (1) year prior to the Consummation Date, a
      customer of Pentacon or any subsidiary thereof, of the Company or of any
      of the Other Founding Companies within the Territory for the purpose of
      soliciting or selling products or services that are in direct competition
      with Pentacon within the Territory;

            (iv) call upon any prospective acquisition candidate, on any
      Stockholder's own behalf or on behalf of any competitor in the fastener
      business, which candidate, to the actual

                                      -48-
<PAGE>
      knowledge of such Stockholder after due inquiry, was called upon by
      Pentacon or any subsidiary thereof or for which, to the actual knowledge
      of such Stockholder after due inquiry, Pentacon or any subsidiary thereof
      made an acquisition analysis, for the purpose of acquiring such entity; or

            (v) disclose customers, whether in existence or proposed, of the
      Company to any person, firm, partnership, corporation or business for any
      reason or purpose relating to the fastener business except to the extent
      that the Company has in the past disclosed such information to the public
      for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any Stockholder from acquiring as a passive investment not more than
one percent (1%) of the capital stock of a competing business whose stock is
traded on a national securities exchange or over-the counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
Pentacon as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to Pentacon for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by Pentacon in the event of breach by such Stockholder,
by injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
Stockholder in light of the activities and business of Pentacon and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of Pentacon; but it is also the intent of Pentacon and the
Stockholder that such covenants be construed and enforced in accordance with the
changing activities; business and locations of Pentacon and its subsidiaries
throughout the term of this covenant. During the term of this covenant, if
Pentacon or one of its subsidiaries engages in new and different activities,
enters a new business or establishes new locations for its current activities or
business in addition to or other than the activities or business it is currently
conducting in the locations currently established therefor, then the Stockholder
will be precluded from soliciting the customers or employees of such new
activities or business or from such new location and from directly competing
with such new activities or business within 100 miles of its then-established
operating location(s) through the term of this covenant.

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

                                      -49-
<PAGE>
      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any Stockholder
against Pentacon or any subsidiary thereof, whether predicated on this Agreement
or otherwise (except for a claim or cause of action based upon Pentacon's
failure to pay or otherwise tender any of the consideration due to the
Stockholder hereunder), shall not constitute a defense to the enforcement by
Pentacon of such covenants. It is specifically agreed that the period of five
(5) years stated at the beginning of this Section 13, during which the
agreements and covenants of each Stockholder made in this Section 13 shall be
effective, shall be computed by excluding from such computation any time during
which such Stockholder is in violation of any provision of this Section 13. The
covenants contained in Section 13 shall not be affected by any breach of any
other provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The Company and the Stockholder hereby agree that this
covenant is a material and substantial part of this transaction.

14.   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1 STOCKHOLDER. The Stockholder recognizes and acknowledges that he has
in the past, currently has, and in the future may possibly have, access to
certain confidential information of the Company, the Other Founding Companies,
and/or Pentacon, such as operational policies, and pricing and cost policies
that are valuable, special and unique assets of the Company's, the Other
Founding Companies' and/or Pentacon's respective businesses. The Stockholder
agrees that he will not disclose such confidential information to any person,
firm, corporation, association or other entity for any purpose or reason
whatsoever, except (a) to authorized representatives of Pentacon, (b) following
the Closing, such information may be disclosed by the Stockholder as is required
in the course of performing his duties for Pentacon or the Surviving Corporation
and (c) to counsel and other advisers, provided that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 14.1, unless
(i) such information becomes known to the public generally through no fault of
the Stockholder, (ii) disclosure is required by law or the order of any
governmental authority under color of law, provided, that prior to disclosing
any information pursuant to this clause (ii), the Stockholder shall, if
possible, give prior written notice thereof to Pentacon and provide Pentacon
with the opportunity to contest such disclosure, or (iii) the disclosing party
reasonably believes that such disclosure is required in connection with the
defense of a lawsuit against the disclosing party. In the event of a breach or
threatened breach by any of the Stockholder of the provisions of this Section,
Pentacon shall be entitled to an injunction restraining such Stockholder from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting Pentacon from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.
In the event the transactions contemplated by this Agreement are not
consummated, Stockholder shall have none of the above-mentioned restrictions on
their ability to disseminate confidential information with respect to the
Company.

      14.2 PENTACON AND NEWCO. Pentacon and Newco recognize and acknowledge that
they had in the past and currently have access to certain confidential
information of the Company, including, but not limited to, customer and prospect
lists, financial information, operational policies, and pricing and cost
policies that are valuable, special and unique assets of the Company's business.
Pentacon and Newco agree that, prior to the Consummation Date, or if the
transactions contemplated by this Agreement are not consummated, they will not,
appropriate or make use of any such information, whether for its own benefit or
the benefit of any other person or entity, for any purpose whatsoever (except
pending the Consummation Date, effecting the transactions contemplated hereby)
disclose such confidential information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, except (a) to
authorized representatives of the Company, (b) to counsel and other advisers,
provided that such advisers (other than counsel) agree to the confidentiality
provisions of this Section 14.2, (c) to the Other Founding Companies and their
representatives pursuant to Section 7.1(a), unless (i) such information becomes
known to the public generally through no fault of Pentacon or Newco, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), Pentacon and Newco shall, if possible, give prior written
notice thereof to the Company and the Stockholder and provide the Company and
the Stockholder with the opportunity to contest such disclosure, or (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, and (d)
to the public to the extent necessary or advisable in connection with the filing
of the Registration Statement and the IPO and the securities laws applicable
thereto and to the operation of Pentacon as a publicly held entity after the
IPO. In the event of a breach or threatened breach by Pentacon or Newco of the
provisions of this Section, the Company and the Stockholder shall be entitled to
an injunction restraining Pentacon and Newco from disclosing, in whole or in
part, such confidential information. Nothing herein shall be construed as
prohibiting the Company and the Stockholder from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.
The foregoing shall not be construed as restricting the last sentence of Section
5 of the Founders Employment Agreement to be entered into between the
Stockholder and the Company effective as of the IPO.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach or threatened breach by any of them of the foregoing
covenants, the covenant may be enforced against the other parties by injunctions
and restraining orders or other appropriate equitable relief, without posting
any bond or other security or having to prove irreparable harm or injury.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Consummation Date, or without limitation if the transactions contemplated hereby
are not consummated.

                                      -51-

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Unless otherwise agreed by Pentacon, except
for transfers to immediate family members who agree to be bound by the
restrictions set forth in this Section 15.1 (or trusts or partnerships for the
benefit of charities, the Stockholder, family members, the trustees or partners
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the Stockholder shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of Pentacon Stock received by the Stockholder in the Merger. The
certificates evidencing the Pentacon Stock delivered to the Stockholder pursuant
to Section 3 of this Agreement will bear a legend substantially in the form set
forth below and containing such other information as Pentacon may deem necessary
or appropriate:

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED
OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT
OR OTHER DISPOSITION PRIOR TO FIRST ANNIVERSARY OF CLOSING DATE. UPON THE
WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE
THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT)
AFTER THE DATE SPECIFIED ABOVE.

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The Stockholder acknowledge that the shares of
Pentacon Stock to be delivered to the Stockholder pursuant to this Agreement
have not been and will not be registered under the 1933 Act (except as provided
in Section 17 hereof) and therefore may not be resold without compliance with
the 1933 Act. The Pentacon Stock to be acquired by such Stockholder pursuant to
this Agreement is being acquired solely for his own respective account, for
investment purposes only, and with no present intention of distributing, selling
or otherwise disposing of it in connection with a distribution. The Stockholder
covenants, warrants and represents that none of the shares of Pentacon Stock
issued to such Stockholder will be offered, sold, assigned, pledged,
hypothecated, transferred or otherwise disposed of except after full compliance
with all of the applicable provisions of the 1933 Act and the rules and
regulations of the SEC. All the Pentacon Stock shall bear the following legend
in addition to the legend required under Section 15 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

                                      -52-
<PAGE>
      16.2 ECONOMIC RISK; SOPHISTICATION. The Stockholder is able to bear the
economic risk of an investment in the Pentacon Stock to be acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment in the
Pentacon Stock. The Stockholder has had an adequate opportunity to ask questions
and receive answers from the officers of Pentacon concerning any and all matters
relating to the transactions described herein including, without limitation, the
background and experience of the current and proposed officers and directors of
Pentacon, the plans for the operations of the business of Pentacon, the
business, operations and financial condition of the Founding Companies other
than the Company, and any plans for additional acquisitions and the like. The
Stockholder has asked any and all questions in the nature described in the
preceding sentence and all questions have been answered to their satisfaction.

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever Pentacon proposes to register any Pentacon Stock for its own or others
account under the 1933 Act for a public offering, other than (i) any shelf or
other registration of shares to be used as consideration for acquisitions of
additional businesses by Pentacon and (ii) registrations relating to employee
benefit plans, Pentacon shall give each of the Stockholder prompt written notice
of its intent to do so. Upon the written request of any of the Stockholder given
within 30 days after receipt of such notice, Pentacon shall cause to be included
in such registration all of the Pentacon Stock issued to the Stockholder
pursuant to this Agreement (including any stock issued as (or issuable upon the
conversion or exchange of any convertible security, warrant, right or other
security which is issued by Pentacon as) a dividend or other distribution with
respect to, or in exchange for, or in replacement of such Pentacon Stock) which
any such Stockholder requests, provided that Pentacon shall have the right to
reduce the number of shares included in such registration to the extent that
inclusion of such shares would, in the written opinion of tax counsel to
Pentacon or its independent auditors, reasonably be likely to jeopardize the
status of the transactions contemplated hereby and by the Registration Statement
as a tax-free organization under Section 351 of the Code. In addition, if
Pentacon is advised in writing in good faith by any managing underwriter of an
underwritten offering of the securities being offered pursuant to any
registration statement under this Section 17.1 that the number of shares to be
sold by persons other than Pentacon is greater than the number of such shares
which can be offered without adversely affecting the offering, Pentacon may
reduce pro rata the number of shares offered for the accounts of such persons
(based upon the number of shares held by such person) to a number deemed
satisfactory by such managing underwriter, provided, that, for each such
offering made by Pentacon after the IPO, such reduction shall be made first by
reducing the number of shares to be sold by persons other than Pentacon, the
Stockholder and the Stockholder of the Other Founding Companies (collectively,
the Stockholder and the Stockholder of the other Founding Companies being
referred to herein as the "Founding Stockholder"), and thereafter, if a further
reduction is required, by reducing the number of shares to be sold by the
Founding Stockholder.

                                      -53-

      17.2 REGISTRATION PROCEDURES. Whenever Pentacon is required to register
shares of Pentacon Stock pursuant to Section 17.1, Pentacon will, as
expeditiously as possible:

            (i) Prepare and file with the SEC a registration statement with
      respect to such shares and use its best efforts to cause such registration
      statement to become effective (provided that before filing a registration
      statement or prospectus or any amendments or supplements or term sheets
      thereto, Pentacon will furnish a representative of the Stockholder with
      copies of all such documents proposed to be filed) as promptly as
      practical;

            (ii) Prepare and file with the SEC such amendments and supplements
      to such registration statement and the prospectus used in connection
      therewith as may be necessary to keep such registration statement
      effective for a period of not less than 120 days;

            (iii) Furnish to each Stockholder who so requests such number of
      copies of such registration statement, each amendment and supplement
      thereto and the prospectus included in such registration statement
      (including each preliminary prospectus and any term sheet associated
      therewith), and such other documents as such Stockholder may reasonably
      request in order to facilitate the disposition of the relevant shares;

            (iv) Use its best efforts to register or qualify the securities
      covered by such registration statement under such other securities or Blue
      Sky laws of such jurisdictions as shall be reasonably requested by the
      Stockholder, and to keep such registration or qualification effective
      during the period such registration statement is to be kept effective,
      provided that Pentacon shall not be required to become subject to
      taxation, to qualify to do business or to file a general consent to
      service of process in any such states or jurisdictions;

            (v) Cause all such shares of Pentacon Stock to be listed or included
      on any securities exchanges or trading systems on which similar securities
      issued by Pentacon are then listed or included;

            (vi) Notify each Stockholder at any time when a prospectus relating
      thereto is required to be delivered under the 1933 Act within the period
      that Pentacon is required to keep the registration statement effective of
      the happening of any event as a result of which the prospectus included in
      such registration statement, together with any associated term sheet,
      contains an untrue statement of a material fact or omits any fact
      necessary to make the statement therein not misleading, and, at the
      request of such Stockholder, Pentacon will prepare a supplement or
      amendment to such prospectus so that, as thereafter delivered to the
      purchasers of the covered shares, such prospectus will not contain an
      untrue statement of material fact or omit to state any fact necessary to
      make the statements therein not misleading.

                                      -54-
<PAGE>
      All expenses incurred in connection with the registration under this
Article 17 (including all registration, filing, qualification, legal, printer
and accounting fees, but excluding underwriting commissions and discounts),
shall be borne by Pentacon.

      17.3  INDEMNIFICATION.

            (a) In connection with any registration hereunder, Pentacon shall
indemnify, to the extent permitted by law, each Stockholder against all losses,
claims, damages, liabilities and expenses arising out of or resulting from any
untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or associated term
sheet or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading except insofar as the same are caused by or contained in or omitted
from any information furnished in writing to Pentacon by such indemnified party
expressly for use therein or by any indemnified parties' failure to deliver a
copy of the registration statement or prospectus or any amendment or supplements
thereto after Pentacon has furnished such Indemnified Party with a sufficient
number of copies of the same.

            (b) In connection with any registration hereunder, each Stockholder
shall furnish to Pentacon in writing such information as is reasonably requested
by Pentacon for use in any such registration statement or prospectus and will
indemnify, to the extent permitted by law, Pentacon, its directors and officers
and each person who controls Pentacon (within the meaning of the 1933 Act)
against any losses, claims, damages, liabilities and expenses resulting from any
untrue or alleged untrue statement or material fact or any omission or alleged
omission of a material fact required to be stated in the registration statement
or prospectus or any amendment thereof or supplement thereto necessary to make
the statements therein not misleading, but only to the extent that such untrue
statement or omission is contained in information so furnished in writing by
such Stockholder specifically for use in preparing the registration statement.
Notwithstanding the foregoing, the liability of a Stockholder under this Section
17.3 shall be limited to an amount equal to the net proceeds actually received
by such Stockholder from the sale of the relevant shares covered by the
registration statement.

            (c) Any person entitled to indemnification under this Section will
(i) give prompt notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified parties'
reasonable judgment, a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. Any failure to give prompt notice shall
deprive a party of its right to indemnification hereunder only to the extent
that such failure shall have adversely affected the indemnifying party. If the
defense of any claim is assumed, the indemnifying party will not be subject to
any liability for any settlement made without its consent (but such consent
shall not be unreasonably withheld). An indemnifying party who is not entitled
or elects not to assume the defense of a claim, will not be obligated to pay the
fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the

                                      -55-
<PAGE>
reasonable judgment of any indemnified party, a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Section 17.1 covering an underwritten registered offering, Pentacon and each
participating holder agree to enter into a written agreement with the managing
underwriters in such form and containing such provisions as are customary in the
securities business for such an arrangement between such managing underwriters
and companies of Pentacon's size and investment stature, including
indemnification.

      17.5 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of Pentacon
stock to the public without registration, Pentacon agrees to use its
commercially reasonable efforts to:

            (i) make and keep public information regarding Pentacon available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of Pentacon under the 1933 Act and the 1934 Act at any
      time after it has become subject to such reporting requirements; and

            (iii) so long as a Stockholder owns any restricted Pentacon Common
      Stock, furnish to each Stockholder forthwith upon written request a
      written statement by Pentacon as to its compliance with the reporting
      requirements of Rule 144 (at any time from and after 90 days following the
      effective date of the Registration Statement, and of the 1933 Act and the
      1934 Act (any time after it has become subject to such reporting
      requirements), a copy of the most recent annual or quarterly report of
      Pentacon, and such other reports and documents so filed as a Stockholder
      may reasonably request in availing itself of any rule or regulation of the
      SEC allowing a Stockholder to sell any such shares without registration.

18.   GENERAL

         and/or lease instruments may be replaced without the consent of
         Pentacon if such replacement instruments are on terms at least as
         favorable to the Company as the instruments being replaced; and

                  (iii) furnish any information to any person other than
         Pentacon, Newco or their authorized agents relating to, any acquisition
         or purchase of all or a material amount of the assets of, or any equity
         interest in, the Company or a merger, consolidation or business
         combination of the Company.

         7.5 NOTICE TO BARGAINING AGENTS. Prior to the Closing Date, the Company
shall satisfy any requirement for notice of the transactions contemplated by
this Agreement under applicable collective bargaining agreements, and shall
provide Pentacon on Schedule 7.5 with proof that any required notice has been
sent.

         7.6 AGREEMENTS. The Stockholders and the Company shall terminate (i)
any stockholders agreements, voting agreements, voting trusts, options, warrants
and employment agreements between the Company and any employee listed on
Schedule 9.12 hereto and (ii) any existing agreement between the Company and any
Stockholder, on or prior to the Consummation Date provided that nothing herein
shall prohibit or prevent the Company from paying (either prior to or on the
Closing Date) notes or other obligations from the Company to the Stockholders in
accordance with the terms thereof, which terms have been disclosed to Pentacon.
Such termination agreements are listed on Schedule 7.6 and copies thereof shall
be attached thereto.

         7.7 NOTIFICATION OF CERTAIN MATTERS BY THE STOCKHOLDERS AND THE
COMPANY. The Stockholders and the Company shall give prompt notice to Pentacon
of (i) the occurrence or non-occurrence of any event the occurrence or
nonoccurrence of which would be likely to cause any representation or warranty
of the Company or the Stockholders contained herein to be untrue or inaccurate
in any material respect at or prior to the Closing and (ii) any material failure
of any Stockholder or the Company to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by such person
hereunder. Pentacon and Newco shall give prompt notice to the Company of (i) the
occurrence or non-occurrence of any event the occurrence or non-occurrence of
which would be likely to cause any representation or warranty of Pentacon or
Newco contained herein to be untrue or inaccurate in any material respect at or
prior to the Closing and (ii)

                                      -32-
<PAGE>
any material failure of Pentacon or Newco to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder. The delivery or deemed delivery of any notice pursuant to this
Section 7.7 shall not be deemed to (i) modify the representations or warranties
hereunder of the party delivering such notice, which modification may only be
made pursuant to Section 7.8, (ii) modify the conditions set forth in Sections 8
and 9, or (iii) limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

         If, prior to the Closing Date, the Chief Executive Officer, the Chief
Financial Officer or the General Counsel of Pentacon shall determine that any of
Pentacon, Newco, the Surviving Corporation or the Company has a claim hereunder
for indemnification against any Stockholder(s) (whether or not such claim might
exceed the Indemnification Threshold), then Pentacon shall promptly advise the
affected Stockholder(s), in writing, of such potential claim and provide
information supporting the basis and potential amount of such claim (a
"Potential Claim Notice"). This procedure with respect to Potential Claim
Notices is intended to afford the affected Stockholder(s) notice so that it may
attempt to cure or otherwise address the claim prior to Closing; provided,
however, that (i) this procedure shall not affect or delay Closing and (ii)
neither the failure or delay by Pentacon to give a Potential Claim Notice nor
the information included or omitted from a Potential Claim Notice shall
constitute a waiver of, or shall otherwise adversely affect the right to receive
indemnification for, any such claim paid by Pentacon, Newco, the Surviving
Corporation or the Company hereunder after the Closing Date.

         7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect
to the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the Company that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect with respect to the Company
may be made unless Pentacon and a majority of the Founding Companies other than
the Company consent to such amendment or supplement; and provided further, that
no amendment or supplement to a Schedule prepared by Pentacon or Newco that
constitutes or reflects an event or occurrence that would have a Material
Adverse Effect with respect to Pentacon or Newco may be made unless a majority
of the Founding Companies consent to such amendment or supplement. For all
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other
Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of the Other Agreements, and such amendment or supplement constitutes
or reflects an event or occurrence that would have a Material Adverse Effect on
such Other Founding Company, Pentacon shall give the

                                      -33-
<PAGE>
Company written notice promptly after it has knowledge thereof. If Pentacon and
a majority of the Founding Companies consent to such amendment or supplement,
which consent shall have been deemed given by Pentacon or any Founding Company
if no response is received within 24 hours following receipt of written notice
of such amendment or supplement (or sooner if reasonable and if required by the
circumstances under which such consent is requested), but the Company does not
give its consent, the Company may terminate this Agreement pursuant to Section
12.1(iv) hereof. In the event that the Company seeks to amend or supplement a
Schedule pursuant to this Section 7.8, and Pentacon and a majority of the Other
Founding Companies do not consent to such amendment or supplement, this
Agreement shall be deemed terminated by mutual consent as set forth in Section
12.1(i) hereof. In the event that Pentacon or Newco seeks to amend or supplement
a Schedule pursuant to this Section 7.8 and a majority of the Founding Companies
do not consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

         7.9 COOPERATION IN PREPARATION OF REGISTRATION STATEMENT. The Company
and Stockholders shall furnish or cause to be furnished to Pentacon and the
Underwriters all of the information concerning the Company and the Stockholders
reasonably required for inclusion in, and will cooperate with Pentacon and the
Underwriters in the preparation of, the Registration Statement and the
prospectus included therein (including audited and unaudited financial
statements, prepared in accordance with generally accepted accounting
principles, in form suitable for inclusion in the Registration Statement, except
that the cost of the preparation of any such audited and unaudited Financial
Statements shall be borne by Pentacon). The Company and the Stockholders agree
promptly to advise Pentacon if at any time during the period in which a
prospectus relating to the IPO is required to be delivered under the Securities
Act, any information contained in the prospectus concerning the Company or the
Stockholders becomes incorrect or incomplete in any material respect, and to
provide the information needed to correct such inaccuracy. Insofar as the
information relates solely to the Company or the Stockholders, the Company
represents and warrants as to such information with respect to itself, and each
Stockholder represents and warrants, as to such information with respect to the
Company and himself or herself, severally, but not jointly, that the information
expressly provided for inclusion in the Registration Statement or otherwise
confirmed in writing by such Stockholder will 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, in light of the circumstances under
which they were made, not misleading.

         7.10 FINAL FINANCIAL STATEMENTS. The Company shall provide prior to the
Consummation Date, and Pentacon shall have had sufficient time to review the
unaudited consolidated balance sheets of the Company as of the end of all fiscal
quarters following the Balance Sheet Date, and the unaudited consolidated
statement of income, cash flows and retained earnings of the Company for all
fiscal quarters ended after the Balance Sheet Date. Such financial statements
shall have been prepared in accordance with generally accepted accounting
principles applied on a

                                      -34-
<PAGE>
consistent basis throughout the periods indicated (except as noted therein).
Except as noted in such financial statements, all of such financial statements
will present fairly the results of operations of the Company for the periods
indicated therein.

         7.11 FURTHER ASSURANCES. The parties hereto agree to execute and
deliver, or cause to be executed and delivered, such further instruments or
documents or take such other action as may be reasonably necessary or convenient
to carry out the transactions contemplated hereby.

         7.12 AUTHORIZED CAPITAL. Prior to the Consummation Date, Pentacon shall
maintain its authorized capital stock as set forth in the Registration Statement
filed with the SEC except for such changes in authorized capital stock as are
made to respond to comments made by the SEC or requirements of any exchange or
automated trading system for which application is made to register the Pentacon
Stock and any changes necessary or advisable in order to permit the delivery of
the opinion contemplated by Section 8.12 hereof.

         7.13 COMPLIANCE WITH THE HART-SCOTT-RODINO-RODINO ANTITRUST
IMPROVEMENTS ACT OF 1976 (THE "HART-SCOTT-RODINO ACT"). All parties to this
Agreement hereby recognize that one or more filings under the Hart-Scott-Rodino
Act may be required in connection with the transactions contemplated herein. If
it is determined by the parties to this Agreement that filings under the
Hart-Scott-Rodino Act are required, then: (i) each of the parties hereto agrees
to cooperate and use its best efforts to comply with the Hart-Scott-Rodino Act,
(ii) such compliance by the Stockholders and the Company shall be deemed a
condition precedent in addition to the conditions precedent set forth in Section
8 of this Agreement, and such compliance by Pentacon and Newco shall be deemed a
condition precedent in addition to the conditions precedent set forth in Section
9 of this Agreement, and (iii) the parties agree to cooperate and use their best
efforts to cause all filings required under the Hart-Scott-Rodino Act to be
made. If filings under the Hart-Scott-Rodino Act are required, the costs and
expenses thereof (including filing fees) shall be borne by Pentacon. The
obligation of each party to consummate the transactions contemplated by this
Agreement is subject to the expiration or termination of the waiting period
under the Hart-Scott-Rodino Act, if applicable.

         7.14 PRE-CLOSING NOTIFICATIONS. If, prior to the 25th day after the
date of the final prospectus of Pentacon utilized in connection with the IPO,
the Company or the Stockholders become aware of any fact or circumstance which
would materially affect the accuracy of a representation or warranty of Company
or Stockholders in this Agreement, the Company and the Stockholders shall
promptly give notice of such fact or circumstance to Pentacon. However, subject
to the provisions of Section 7.8, such notification shall not relieve either the
Company or the Stockholders of their respective obligations under this
Agreement, and, subject to the provisions of Section 7.8, at the sole option of
Pentacon, the truth and accuracy of any and all warranties and representations
of the Company, or on behalf of the Company and of Stockholders at the date of
this Agreement and on the Closing Date and on the Consummation Date, shall be a
precondition to the consummation of this transaction.

         7.15 PAYMENT OF INDEBTEDNESS. On the Consummation Date, immediately
following the Effective Time of the Merger, Pentacon will pay, or cause to be
paid, all of the outstanding liabilities, obligations and indebtedness of
Company to the lenders identified on Schedule 7.15 hereto. In connection with
such repayment of indebtedness, all associated guaranties of Founder
Stockholders shall be terminated and cancelled.

         7.16 MINIMUM VALUE. All of the parties to this Agreement recognize that
one of the conditions to the Stockholders consummating the transactions
contemplated herein is that the IPO shall be closed and the Stockholders (as a
group) shall be entitled to receive consideration not less than the Minimum
Value set forth on Annex I attached hereto.

         7.17 DIRECTORS. Pentacon agrees that the number of directors of
Pentacon shall not exceed nine members immediately following the IPO unless the
Founding Stockholder representatives to serve on such board agree in writing to
a larger number of directors.

         7.18 TRANSACTION REPORTING. Pentacon agrees that, except as otherwise
required by applicable law, Pentacon will describe or report the transaction in
any required tax reports of Pentacon as a tax-free transaction (insofar as its
relates to the delivery of Pentacon Stock for Company Stock) in a manner
consistent with the tax opinion referenced in Section 8.12.

         7.19 PERMITS. Pentacon agrees, prior to the Consummation Date, to
obtain all material Licenses necessary for Pentacon to commence the conduct of

contained in Section 6 hereof or the rights of the Stockholders pursuant to

         shall file or cause to be filed all Tax Returns (federal, state, local
         or otherwise) of any Acquired Party for all taxable periods that end on
         or before the Consummation Date. Pentacon shall be given the
         opportunity to review all such Returns prior to such filings. Unless
         the Company is a C corporation, the Stockholders shall pay or cause to
         be paid all Tax liabilities (in excess of all amounts already paid with
         respect thereto or properly accrued or reserved with respect thereto on
         the Financial Statements) shown by such Returns to be due, subject to
         the provisions of 7.3(iii).

                  (ii) Pentacon shall file or cause to be filed all separate

         determining a liability for Taxes or a right to refund of Taxes or in

         expense of the requesting party, of all relevant portions of relevant
         Returns, together with relevant accompanying schedules and relevant
         work papers, relevant documents relating to rulings or other

         Each party shall make its employees reasonably available on a mutually
         convenient basis at its cost to provide explanation of any documents or
         information so provided. Subject to the preceding sentence, each party
         required to file Returns pursuant to this Agreement shall bear all
         costs of filing such Returns.

                                      -41-

11.      INDEMNIFICATION

         The Stockholders, Pentacon and Newco each make the following covenants
that are applicable to them, respectively:

         11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS. The Stockholders
covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless Pentacon, Newco, the Company and the Surviving
Corporation at all times, from and after the date of this Agreement until the
Expiration Date (provided that for purposes of Section 11.1(iii) below, the
Expiration Date shall be the date on which the applicable statute of limitations
expires), from and against all claims, damages, actions, suits, proceedings,
demands, assessments, adjustments, costs and expenses (including specifically,
but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by Pentacon, Newco, the Company or the Surviving
Corporation as a result of or arising from (i) any breach of the representations
and warranties of the Stockholders or the Company set forth herein or on the
definitive, final schedules or certificates delivered by them in connection
herewith, (ii) any breach of any agreement on the part of the Stockholders or,
prior to Closing, the Company under this Agreement, or (iii) any liability under
the 1933 Act, the 1934 Act or other Federal or state law or regulation, at
common law or otherwise, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact relating to the Company or the
Stockholders, and provided in writing to Pentacon or its counsel by the Company
or the Stockholders for inclusion in the Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact relating to the Company or the Stockholders
required to be stated therein or necessary to make the statements therein not
misleading, provided, however, that such indemnity shall not inure to the
benefit of Pentacon, Newco, the Company or the Surviving Corporation to the
extent that such untrue statement (or alleged untrue statement) was made in, or
omission (or alleged omission) occurred in, any preliminary prospectus and the
Stockholders provided, in writing, corrected information to Pentacon counsel and
to Pentacon for inclusion in the final prospectus, and such information was not
so included or properly delivered, and provided further, that no Stockholder
shall be liable for any indemnification obligation pursuant to this

                                      -42-
<PAGE>
Section 11.1(iii) to the extent attributable to a breach of any representation,
warranty or agreement made herein individually by any other Stockholder.

         Pentacon and Newco acknowledge and agree that other than the
representations and warranties of Company or Stockholders specifically contained
in this Agreement, there are no representations or warranties of Company or
Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

         Pentacon, Newco and the Company further acknowledge and agree that,
should the Closing occur, their sole and exclusive remedy with respect to any
and all claims relating to this Agreement and the transactions contemplated in
this Agreement, shall be pursuant to the indemnification provisions set forth in
this Section 11.1. Pentacon, Newco and the Company hereby waive, from and after
the Closing, to the fullest extent permitted under applicable law, any and all
rights, claims and causes of action they or any indemnified person may have
against the Company or any Stockholder relating to this Agreement or the
transactions contemplated hereby arising under or based upon any federal, state,
local or foreign statute, law, rule, regulation or otherwise (and other than
pursuant to the terms of this Agreement).

         11.2 INDEMNIFICATION BY PENTACON. Pentacon covenants and agrees that it
will indemnify, defend, protect and hold harmless the Stockholders at all times
from and after the date of this Agreement until the Expiration Date, from and
against all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
Stockholders as a result of or arising from (i) any breach by Pentacon or Newco
of their representations and warranties set forth herein or on the definitive,
final schedules or certificates attached delivered by them pursuant hereto, (ii)
any breach of any agreement on the part of Pentacon or Newco under this
Agreement or any other agreement delivered pursuant hereto, (iii) any
liabilities which the Stockholders may incur due to Pentacon's or Newco's or the
Surviving Corporation's failure to pay, perform or discharge when due any of the
liabilities and obligations of the Company for which Pentacon, Newco or the
Surviving Corporation is responsible pursuant to this Agreement (except to the
extent that Pentacon or Newco has bona fide claims hereunder against the
Stockholders by reason of such liabilities); or (iv) any liability under the
1933 Act, the 1934 Act or other Federal or state law or regulation, at common
law or otherwise, arising out of or based upon any untrue statement or alleged
untrue statement of a material fact relating to Pentacon, Newco or any of the
Other Founding Companies contained in any preliminary prospectus, the
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to
Pentacon or Newco or any of the Other Founding Companies required to be stated
therein or necessary to make the statements therein not misleading.

<PAGE>
         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has actual knowledge of any
claim by a Person (including any governmental agency) not a party to this
Agreement ("Third Person"), or the commencement of any action or proceeding by a
Third Person, with respect to which the Indemnified Person would be entitled to
receive indemnification pursuant to Section 11, the Indemnified Party shall, as
a condition precedent to a claim with respect thereto being made against any
party obligated to provide indemnification pursuant to Section 11.1 or 11.2
hereof (hereinafter the "Indemnifying Party"), give the Indemnifying Party
written notice of such claim or the commencement of such action or proceeding.
Such notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party, Indemnified
Party shall have the right to participate in such matter through counsel of its
own choosing and Indemnifying Party will reimburse the Indemnified Party for the
reasonable expenses of its counsel. After the Indemnifying Party has notified
the Indemnified Party of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnifying Party diligently pursues
such defense through appropriate proceedings, the Indemnifying Party shall not
be liable for any additional legal expenses incurred by the Indemnified Party in
connection with any defense or settlement of such asserted liability, except (i)
as set forth in the preceding sentence and (ii) to the extent such participation
is requested by the Indemnifying Party, in which event the Indemnified Party
shall be reimbursed by the Indemnifying Party for reasonable additional legal
expenses and out-of-pocket expenses. If the Indemnifying Party desires to accept
a final and complete settlement of any such Third Person claim and the
Indemnified Party refuses to consent to such settlement, then the Indemnifying
Party's liability under this Section with respect to such Third Person claim
shall be limited to the amount so offered in settlement by said Third Person.
Upon agreement as to such settlement between said Third Person and the
Indemnifying Party, the Indemnifying Party shall, in exchange for a complete
release from the Indemnified Party, promptly pay to the Indemnified Party the
amount agreed to in such settlement and the Indemnified Party shall, from that
moment on, bear full responsibility for any additional costs of defense which it
subsequently incurs with respect to such claim and all additional costs of
settlement or judgment. If the Indemnifying Party does not undertake to defend
such matter to which the Indemnified Party is entitled to indemnification
hereunder, or fails diligently to pursue such defense, the Indemnified Party may
undertake such defense through counsel of its choice, at the cost and expense of
the Indemnifying Party, and the Indemnified Party may settle such matter, and
the Indemnifying Party shall reimburse the

                                      -44-
<PAGE>
Indemnified Party for the amount paid in such settlement and any other
liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

         11.4 EXCLUSIVE REMEDY. (a) The indemnification provided for in this
Section 11 shall (except as prohibited by ERISA) be the exclusive remedy in any
action seeking damages or any other form of monetary relief brought by any party
to this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case pursuant to Section
14.3 or otherwise, to seek injunctive or other equitable relief (except for
rescission which shall not be available) for a breach or threatened breach of
this Agreement. Any indemnity payment under this Section 11 shall be treated as
an adjustment to the exchange consideration for tax purposes unless a final
determination (which shall include the execution of a Form 870-AD or successor
form) with respect to the indemnified party or any of its affiliate causes any
such payment not to be treated as an adjustment to the exchange consideration
for U.S. Federal Income Tax purposes.

                  (b) Nothing in this Article 11 shall restrict the Stockholders
from subrogation or seeking reimbursement from third parties other than the
Company.

         11.5 LIMITATIONS ON INDEMNIFICATION. Pentacon, Newco, the Surviving
Corporation and the other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall not assert any claim for indemnification hereunder against
the Stockholders after the applicable Expiration Date and in no event until such
time as, and solely to the extent that, the aggregate of all claims which such
persons may have against the Stockholders shall exceed the greater of 1% of the
value of the total consideration (including stock and cash) received by the
Stockholders from the Merger or $100,000 (the "Indemnification Threshold"), and
then only to the extent of the excess over the Indemnification Threshold.
Stockholders shall not assert any claim for indemnification hereunder against
Pentacon or Newco after the applicable Expiration Date and in no event until
such time as, and solely to the extent that, the aggregate of all claims which
Stockholders may have against Pentacon or Newco shall exceed the Indemnification
Threshold, and then only to the extent of the excess over the Indemnification
Threshold.

         The Indemnification Threshold shall not be applicable to any breach of
covenants made by the Stockholders in this Agreement which require an action or
inaction by such Stockholders from and after the Closing Date (I.E., Article 10,
Article 11, Article 13, Article 14, Article 17 and Section 18.1). No person
shall be entitled to indemnification under this Section 11 if, and only to the
extent that such person's claim for indemnification is directly related to a
breach by such person of any representation, warranty, covenant or other
agreement set forth in this Agreement.

                                      -45-
<PAGE>
         The pursuit by Pentacon, the Surviving Corporation, Newco or the
Company, of any claim for indemnification hereunder against a Stockholder shall
require a majority vote of the board of directors of Pentacon, excluding for the
purposes of such vote any director who was previously a stockholder of the
Company or is a representative of the stockholders of the Company as existing
prior to the closing of the transaction contemplated in this Agreement.

         Notwithstanding any other term of this Agreement, no Stockholder shall
be liable (in the aggregate from time to time taking into account all
indemnification payments made hereunder) under this Section 11 (a) for any
amount which is less than or equal to the Indemnification Threshold (and then
only to the extent of the excess over the Indemnification Threshold) or (b) for
any amount which exceeds the amount of proceeds (including cash and stock)
received by such Stockholder in connection with the Merger. Each Stockholder
shall have the option of satisfying his or her indemnity obligation in cash
and/or by returning or transferring shares of Pentacon Stock to Pentacon or any
other Indemnified Party. For purposes of calculating the value of the Pentacon
Stock received by a Stockholder and satisfying any indemnity claim by returning
or transferring Pentacon Stock, Pentacon Stock shall be valued at its initial
public offering price as set forth in the Registration Statement.

         Notwithstanding any of the foregoing provisions of this Section 11 that
might be read to the contrary, it is the agreement of the parties that the
Indemnification Threshold be given full effect under all circumstances.
Accordingly, insofar as any of the foregoing provisions of this Section 11 may
hold harmless an Indemnified Party before the Indemnification Threshold has been
met, then Pentacon and the Stockholders shall cooperate in good faith to
establish an equitable procedure pursuant to which Pentacon reimburses or causes
the reimbursement to the affected Stockholder(s) of all expenditures and
payments by Stockholders that are intended to be absorbed and borne by any
Indemnified Parties as a result of the prior application of the Indemnification
Threshold or otherwise takes such action as may be reasonably necessary to give
effect to the Indemnification Threshold.

12.      TERMINATION OF AGREEMENT

         12.1 TERMINATION. This Agreement may be terminated at any time prior to
the Consummation Date solely:

                  (i) by mutual consent of the boards of directors of Pentacon
         and the Company;

                  (ii) by the Stockholders or the Company (acting through its
         board of directors), on the one hand, or by Pentacon (acting through
         its board of directors), on the other hand, if the transactions
         contemplated by this Agreement to take place at the Closing shall not
         have been consummated by February 28, 1998, unless the failure of such
         transactions to be consummated is due to the willful failure of the
         party seeking to terminate this Agreement to perform any of its
         obligations under this Agreement to the extent required to be performed
         by it prior to or on the Consummation Date;

                                      -46-
<PAGE>
                  (iii) by the Stockholders or Company, on the one hand, or by
         Pentacon, on the other hand, if a material breach or default shall be
         made by the other party in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein, and
         the curing of such default shall not have been made on or before the
         Consummation Date or by the Stockholders or the Company, if the
         conditions set forth in Section 8 hereof have not been satisfied or
         waived as of the Closing Date or the Consummation Date, as applicable,
         or by Pentacon, if the conditions set forth in Section 9 hereof have
         not been satisfied or waived as of the Closing Date or the Consummation
         Date, as applicable;

                  (iv) pursuant to Section 7.8 hereof;

                  (v) pursuant to the termination provisions contained in
         Section 4 hereof; or

                  (vi) pursuant to the other express terms of this Agreement.

         12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.      NONCOMPETITION

         business, which candidate, to the actual knowledge of such Stockholder
         after due inquiry, was called upon by Pentacon or any subsidiary
         thereof or for which, to the actual knowledge of such Stockholder after
         due inquiry, Pentacon or any subsidiary thereof made an acquisition
         analysis, for the purpose of acquiring such entity; or

                  (v) disclose customers, whether in existence or proposed, of
         the Company to any person, firm, partnership, corporation or business
         for any reason or purpose relating to the fastener business except to
         the extent that the Company has in the past disclosed such information
         to the public for valid business reasons.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment not more than
one percent (1%) of the capital stock of a competing business whose stock is
traded on a national securities exchange or over-the counter.

         13.2 DAMAGES. Because of the difficulty of measuring economic losses to
Pentacon as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to Pentacon for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by Pentacon in the event of breach by such Stockholder,
by injunctions and restraining orders.

         13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
Stockholders in light of the activities and business of Pentacon and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of Pentacon; but it is also the intent of Pentacon and the
Stockholders that such covenants be construed and enforced in accordance with
the changing activities; business and locations of Pentacon and its subsidiaries
throughout the term of this covenant. During the term of this covenant, if
Pentacon or one of its subsidiaries engages in new and different activities,
enters a new business or establishes new locations for its current activities or
business in addition to or other than the activities or business it is currently
conducting in the locations currently established therefor, then the
Stockholders will be precluded from soliciting the customers or employees of
such new activities or business or from such new location and from directly
competing with such new activities or business within 100 miles of its
then-established operating location(s) through the term of this covenant.

                                      -48-
<PAGE>
         13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

         13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13
shall be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any Stockholder
against Pentacon or any subsidiary thereof, whether predicated on this Agreement
or otherwise (except for a claim or cause of action based upon Pentacon's
failure to pay or otherwise tender any of the consideration due to the
Stockholders hereunder), shall not constitute a defense to the enforcement by
Pentacon of such covenants. It is specifically agreed that the period of five
(5) years stated at the beginning of this Section 13, during which the
agreements and covenants of each Stockholder made in this Section 13 shall be
effective, shall be computed by excluding from such computation any time during
which such Stockholder is in violation of any provision of this Section 13. The
covenants contained in Section 13 shall not be affected by any breach of any
other provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

         13.6 MATERIALITY. The Company and the Stockholders hereby agree that
this covenant is a material and substantial part of this transaction.

14.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION

         14.1 STOCKHOLDERS. The Stockholders recognize and acknowledge that they
had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the Company, the Other Founding Companies,
and/or Pentacon, such as operational policies, and pricing and cost policies
that are valuable, special and unique assets of the Company's, the Other
Founding Companies' and/or Pentacon's respective businesses. The Stockholders
agree that they will not disclose such confidential information to any person,
firm, corporation, association or other entity for any purpose or reason
whatsoever, except (a) to authorized representatives of Pentacon, (b) following
the Closing, such information may be disclosed by the Stockholders as is
required in the course of performing their duties for Pentacon or the Surviving
Corporation and (c) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, unless (i) such information becomes known to the public generally through
no fault of the Stockholders, (ii) disclosure is required by law or the order of
any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), the Stockholders shall,
if possible, give prior written notice thereof to Pentacon and provide Pentacon
with the opportunity to contest such disclosure, or (iii) the disclosing party
reasonably believes that such disclosure is required in connection with the
defense of a lawsuit against the disclosing party. In the event of a breach or
threatened breach by any of the Stockholders of the provisions of this Section,
Pentacon shall be entitled to an injunction restraining such

                                      -49-
<PAGE>
Stockholders from disclosing, in whole or in part, such confidential
information. Nothing herein shall be construed as prohibiting Pentacon from
pursuing any other available remedy for such breach or threatened breach,
including the recovery of damages. In the event the transactions contemplated by
this Agreement are not consummated, Stockholders shall have none of the
above-mentioned restrictions on their ability to disseminate confidential
information with respect to the Company.

         14.2 PENTACON AND NEWCO. Pentacon and Newco recognize and acknowledge
that they had in the past and currently have access to certain confidential
information of the Company, including, but not limited to, customer and prospect
lists, financial information, operational policies, and pricing and cost
policies that are valuable, special and unique assets of the Company's business.
Pentacon and Newco agree that, prior to the Consummation Date, or if the
transactions contemplated by this Agreement are not consummated, they will not,
appropriate or make use of any such information, whether for its own benefit or
the benefit of any other person or entity, for any purpose whatsoever (except
pending the Consummation Date, effecting the transactions contemplated hereby)
disclose such confidential information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, except (a) to
authorized representatives of the Company, (b) to counsel and other advisers,
provided that such advisers (other than counsel) agree to the confidentiality
provisions of this Section 14.2, (c) to the Other Founding Companies and their
representatives pursuant to Section 7.1(a), unless (i) such information becomes
known to the public generally through no fault of Pentacon or Newco, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), Pentacon and Newco shall, if possible, give prior written
notice thereof to the Company and the Stockholders and provide the Company and
the Stockholders with the opportunity to contest such disclosure, or (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, and (d)
to the public to the extent necessary or advisable in connection with the filing
of the Registration Statement and the IPO and the securities laws applicable
thereto and to the operation of Pentacon as a publicly held entity after the
IPO. In the event of a breach or threatened breach by Pentacon or Newco of the
provisions of this Section, the Company and the Stockholders shall be entitled
to an injunction restraining Pentacon and Newco from disclosing, in whole or in
part, such confidential information. Nothing herein shall be construed as
prohibiting the Company and the Stockholders from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.

         14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach or threatened breach by any of them of the foregoing
covenants, the covenant may be enforced against the other parties by injunctions
and restraining orders or other appropriate equitable relief, without posting
any bond or other security or having to prove irreparable harm or injury.

                                      -50-
<PAGE>
         14.4 SURVIVAL. The obligations of the parties under this Article 14
shall survive the termination of this Agreement for a period of five years from
the Consummation Date, or without limitation if the transactions contemplated
hereby are not consummated.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS. Unless otherwise agreed by Pentacon, except
for transfers to immediate family members who agree to be bound by the
restrictions set forth in this Section 15.1 (or trusts or partnerships for the
benefit of charities, the Stockholders, family members, the trustees or partners
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the Stockholders shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of Pentacon Stock received by the Stockholders in the Merger. The
certificates evidencing the Pentacon Stock delivered to the Stockholders
pursuant to Section 3 of this Agreement will bear a legend substantially in the
form set forth below and containing such other information as Pentacon may deem
necessary or appropriate:

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED
OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT
OR OTHER DISPOSITION PRIOR TO FIRST ANNIVERSARY OF CLOSING DATE. UPON THE
WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE
THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT)
AFTER THE DATE SPECIFIED ABOVE.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. The Stockholders acknowledge that the shares
of Pentacon Stock to be delivered to the Stockholders pursuant to this Agreement
have not been and will not be registered under the 1933 Act (except as provided
in Section 17 hereof) and therefore may not be resold without compliance with
the 1933 Act. The Pentacon Stock to be acquired by such Stockholders pursuant to
this Agreement is being acquired solely for their own respective accounts, for
investment purposes only, and with no present intention of distributing, selling
or otherwise disposing of it in connection with a distribution. The Stockholders
covenant, warrant and represent that none of the shares of Pentacon Stock issued
to such Stockholders will be offered, sold, assigned, pledged, hypothecated,
transferred or otherwise disposed of except after full compliance with all of
the applicable provisions of the 1933 Act and the rules and regulations of the
SEC. All the Pentacon Stock shall bear the following legend in addition to the
legend required under Section 15 of this Agreement:

                                      -51-
<PAGE>
THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

         16.2 ECONOMIC RISK; SOPHISTICATION. The Stockholders are able to bear
the economic risk of an investment in the Pentacon Stock to be acquired pursuant
to this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment in the
Pentacon Stock. The Stockholders party hereto have had an adequate opportunity
to ask questions and receive answers from the officers of Pentacon concerning
any and all matters relating to the transactions described herein including,
without limitation, the background and experience of the current and proposed
officers and directors of Pentacon, the plans for the operations of the business
of Pentacon, the business, operations and financial condition of the Founding
Companies other than the Company, and any plans for additional acquisitions and
the like. The Stockholders have asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever Pentacon proposes to register any Pentacon Stock for its own or others
account under the 1933 Act for a public offering, other than (i) any shelf or
other registration of shares to be used as consideration for acquisitions of
additional businesses by Pentacon and (ii) registrations relating to employee
benefit plans, Pentacon shall give each of the Stockholders prompt written
notice of its intent to do so. Upon the written request of any of the
Stockholders given within 30 days after receipt of such notice, Pentacon shall
cause to be included in such registration all of the Pentacon Stock issued to
the Stockholders pursuant to this Agreement (including any stock issued as (or
issuable upon the conversion or exchange of any convertible security, warrant,
right or other security which is issued by Pentacon as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such
Pentacon Stock) which any such Stockholder requests, provided that Pentacon
shall have the right to reduce the number of shares included in such
registration to the extent that inclusion of such shares would, in the written
opinion of tax counsel to Pentacon or its independent auditors, reasonably be
likely to jeopardize the status of the transactions contemplated hereby and by
the Registration Statement as a tax-free organization under Section 351 of the
Code. In addition, if Pentacon is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than Pentacon is greater than the number
of such shares which can be offered without adversely affecting the offering,
Pentacon may reduce pro rata the number of shares offered for the accounts of
such persons (based upon the number of shares held by such person) to a number
deemed satisfactory by such managing underwriter, provided, that, for each such
offering made by Pentacon after the IPO, such reduction shall be made first by
reducing the number of shares to be sold by persons other than Pentacon, the

                                      -52-
<PAGE>
Stockholders and the Stockholders of the Other Founding Companies (collectively,
the Stockholders and the Stockholders of the other Founding Companies being
referred to herein as the "Founding Stockholders"), and thereafter, if a further
reduction is required, by reducing the number of shares to be sold by the
Founding Stockholders.

         17.2 REGISTRATION PROCEDURES. Whenever Pentacon is required to register
shares of Pentacon Stock pursuant to Section 17.1, Pentacon will, as
expeditiously as possible:

                  (i) Prepare and file with the SEC a registration statement
         with respect to such shares and use its best efforts to cause such
         registration statement to become effective (provided that before filing
         a registration statement or prospectus or any amendments or supplements
         or term sheets thereto, Pentacon will furnish a representative of the
         Stockholders with copies of all such documents proposed to be filed) as
         promptly as practical;

                  (ii) Prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection therewith as may be necessary to keep such registration
         statement effective for a period of not less than 120 days;

                  (iii) Furnish to each Stockholder who so requests such number
         of copies of such registration statement, each amendment and supplement
         thereto and the prospectus included in such registration statement
         (including each preliminary prospectus and any term sheet associated
         therewith), and such other documents as such Stockholder may reasonably
         request in order to facilitate the disposition of the relevant shares;

                  (iv) Use its best efforts to register or qualify the
         securities covered by such registration statement under such other
         securities or Blue Sky laws of such jurisdictions as shall be
         reasonably requested by the Stockholders, and to keep such registration
         or qualification effective during the period such registration
         statement is to be kept effective, provided that Pentacon shall not be
         required to become subject to taxation, to qualify to do business or to
         file a general consent to service of process in any such states or
         jurisdictions;

                  (v) Cause all such shares of Pentacon Stock to be listed or
         included on any securities exchanges or trading systems on which
         similar securities issued by Pentacon are then listed or included;

                  (vi) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that Pentacon is required to keep the registration statement
         effective of the happening of any event as a result of which the
         prospectus included in such registration statement, together with any
         associated term sheet, contains an untrue statement of a material fact
         or omits any fact necessary to make the statement therein not
         misleading, and, at the request of such Stockholder, Pentacon will
         prepare a supplement or amendment to such prospectus so that, as
         thereafter delivered to the

                                      -53-
<PAGE>
         purchasers of the covered shares, such prospectus will not contain an
         untrue statement of material fact or omit to state any fact necessary
         to make the statements therein not misleading.

         All expenses incurred in connection with the registration under this
Article 17 (including all registration, filing, qualification, legal, printer
and accounting fees, but excluding underwriting commissions and discounts),
shall be borne by Pentacon.

         17.3     INDEMNIFICATION.

                  (a) In connection with any registration hereunder, Pentacon
shall indemnify, to the extent permitted by law, each Stockholder against all
losses, claims, damages, liabilities and expenses arising out of or resulting
from any untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or associated term
sheet or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading except insofar as the same are caused by or contained in or omitted
from any information furnished in writing to Pentacon by such indemnified party
expressly for use therein or by any indemnified parties' failure to deliver a
copy of the registration statement or prospectus or any amendment or supplements
thereto after Pentacon has furnished such Indemnified Party with a sufficient
number of copies of the same.

                  (b) In connection with any registration hereunder, each
Stockholder shall furnish to Pentacon in writing such information as is
reasonably requested by Pentacon for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, Pentacon, its
directors and officers and each person who controls Pentacon (within the meaning
of the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged untrue statement or material fact or any
omission or alleged omission of a material fact required to be stated in the
registration statement or prospectus or any amendment thereof or supplement
thereto necessary to make the statements therein not misleading, but only to the
extent that such untrue statement or omission is contained in information so
furnished in writing by such Stockholder specifically for use in preparing the
registration statement. Notwithstanding the foregoing, the liability of a
Stockholder under this Section 17.3 shall be limited to an amount equal to the
net proceeds actually received by such Stockholder from the sale of the relevant
shares covered by the registration statement.

                  (c) Any person entitled to indemnification under this Section
will (i) give prompt notice to the indemnifying party of any claim with respect
to which it seeks indemnification and (ii) unless in such indemnified parties'
reasonable judgment, a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. Any failure to give prompt notice shall
deprive a party of its right to indemnification hereunder only to the extent
that such failure shall have adversely affected the indemnifying party. If the
defense of any claim is assumed, the indemnifying party will not be

                                      -54-
<PAGE>
subject to any liability for any settlement made without its consent (but such
consent shall not be unreasonably withheld). An indemnifying party who is not
entitled or elects not to assume the defense of a claim, will not be obligated
to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party, a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim.

         17.4 UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Section 17.1 covering an underwritten registered offering, Pentacon
and each participating holder agree to enter into a written agreement with the
managing underwriters in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
managing underwriters and companies of Pentacon's size and investment stature,
including indemnification.

         17.5 RULE 144 REPORTING. With a view to making available the benefits
of certain rules and regulations of the SEC that may permit the sale of Pentacon
stock to the public without registration, Pentacon agrees to use its
commercially reasonable efforts to:

                  (i) make and keep public information regarding Pentacon
         available as those terms are understood and defined in Rule 144 under
         the 1933 Act for a period of four years beginning 90 days following the
         effective date of the Registration Statement;

                  (ii) file with the SEC in a timely manner all reports and
         other documents required of Pentacon under the 1933 Act and the 1934
         Act at any time after it has become subject to such reporting
         requirements; and

                  (iii) so long as a Stockholder owns any restricted Pentacon
         Common Stock, furnish to each Stockholder forthwith upon written
         request a written statement by Pentacon as to its compliance with the
         reporting requirements of Rule 144 (at any time from and after 90 days
         following the effective date of the Registration Statement, and of the
         1933 Act and the 1934 Act (any time after it has become subject to such
         reporting requirements), a copy of the most recent annual or quarterly
         report of Pentacon, and such other reports and documents so filed as a
         Stockholder may reasonably request in availing itself of any rule or
         regulation of the SEC allowing a Stockholder to sell any such shares
         without registration.

18.      GENERAL

         18.1 COOPERATION. The Company, Stockholders, Pentacon and Newco shall
each deliver or cause to be delivered to the other on the Consummation Date, and
at such other times and places as shall be reasonably agreed to, such additional
instruments as the other may reasonably request for the purpose of carrying out
this Agreement. The Company will cooperate and use its reasonable efforts to
have the present officers, directors and employees of the Company cooperate with
Pentacon on and after the Consummation Date in furnishing information, evidence,
testimony and

                                      -55-
<PAGE>
other assistance in connection with any tax return filing obligations, actions,
proceedings, arrangements or disputes of any nature with respect to matters
pertaining to all periods prior to the Consummation Date.

         18.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law) and shall be
binding upon and shall inure to the benefit of the parties hereto, the
successors of Pentacon, and the heirs and legal representatives of the
Stockholders.

         18.3 ENTIRE AGREEMENT. This Agreement (including the schedules,
exhibits and annexes attached hereto) and the documents delivered pursuant
hereto constitute the entire agreement and understanding among the Stockholders,
the Company, Newco and Pentacon and supersede any prior agreement and
understanding relating to the subject matter of this Agreement. This Agreement,
upon execution, constitutes a valid and binding agreement of the parties hereto
enforceable in accordance with its terms and may be modified or amended only (i)
pursuant to Section 7.8 with respect to the amendment of Schedules or (ii) by a
written instrument executed by the Stockholders, the Company, Newco and
Pentacon, acting through their respective officers or trustees, duly authorized
by their respective Boards of Directors. Any disclosure made on any Schedule
delivered pursuant hereto shall be deemed to have been disclosed for purposes of
any other Schedule required hereby, provided that the Company shall make a good
faith effort to cross reference disclosure, as necessary or advisable, between
related Schedules, and provided further that the failure to do so will not
affect the validity of such disclosure.

         18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

         18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each
party represents and warrants that it employed no broker or agent in connection
with this transaction and agrees to indemnify the other parties hereto against
all loss, cost, damages or expense arising out of claims for fees or commission
of brokers employed or alleged to have been employed by such indemnifying party.

         18.6 EXPENSES. Whether or not the transactions herein contemplated
shall be consummated, Pentacon will pay the fees, expenses and disbursements of
Pentacon and its agents, representatives, accountants and counsel incurred in
connection with the subject matter of this Agreement and any amendments thereto,
including all costs and expenses incurred in the performance and compliance with
all conditions to be performed by Pentacon under this Agreement, including the

("Transfer Taxes") imposed in connection with the Merger, other than Transfer
Taxes, if any, imposed by the State of Delaware. Each Stockholder shall file all
necessary documentation and Returns with respect to such Transfer Taxes. In
addition, each Stockholder acknowledges that he, and not the Company or
Pentacon, will pay all taxes due upon receipt of the consideration payable
pursuant to Section 2 hereof. The Stockholders acknowledge that the risks of the
transactions contemplated hereby include tax risks, with respect to which the
Stockholders are relying solely on the opinion contemplated by Section 8.12
hereof.

         18.7 NOTICES. All notices of communication required or permitted

has any obligation to contribute to or accrue or pay any benefits under any
deferred compensation or retirement funding arrangement on behalf of any
employee or employees (such as, for example, and without limitation, any
individual retirement account or annuity, any "excess benefit plan" (within the
meaning of Section 3(36) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA")) or any non-qualified deferred compensation arrangement).
For the purposes of this Agreement, the term "employee pension benefit plan"

Company has not sponsored, maintained or contributed to any employee pension
benefit plan other than the plans set forth on Schedule 5.19, and the Company is
not or could not be required to contribute to any retirement plan pursuant to
the provisions of any collective bargaining agreement establishing the terms and

as a result of its past activities become, liable to the Pension Benefit
Guaranty Corporation ("PBGC") or to any multiemployer employee pension benefit
plan under the provisions of Title IV of ERISA.

      All employee benefit plans listed on Schedule 5.19 and the administration
thereof are in compliance with their terms and all applicable provisions of
ERISA and the regulations issued thereunder, as well as with all other
applicable federal, state and local statutes, ordinances and regulations.

      All accrued contribution obligations of the Company with respect to any
plan listed on Schedule 5.19 as of the Balance Sheet Date have either been
fulfilled in their entirety or are fully reflected on the Interim Balance Sheet
as of the Balance Sheet Date.

      5.20 COMPLIANCE WITH ERISA. Except as set forth on Schedule 5.20, all such
plans listed on Schedule 5.19 that are intended to qualify (the "Qualified
Plans") under Section 401 (a) of the Code are, and have been so qualified and
have been determined by the Internal Revenue Service to be so qualified, and
copies of the most recent determination letters with respect thereto are
attached to Schedule 5.19. Except as disclosed on Schedule 5.20, all reports and
other documents required to be filed with any governmental agency or distributed
to plan participants or beneficiaries (including, but not limited to, actuarial
reports, audits or tax returns) have been timely filed or distributed, and
copies of the most recent reports and filing relating thereto are included as
part of Schedule 5.19 hereof. Neither the Stockholders, the Other Stockholders,
any such plan listed in Schedule 5.19, nor the Company has engaged in any
transaction prohibited under the provisions of Section 4975 of the Code or
Section 406 of ERISA. No such Plan listed in Schedule 5.19 has incurred an
accumulated funding deficiency, as defined in Section 412(a) of the Code and
Section 302(l) of ERISA; and the Company has not incurred any liability for
excise tax or penalty due to the Internal Revenue Service nor any liability to
the PBGC. The Stockholders further represent that except as set forth on
Schedule 5.19 hereto:

      qualify under Section 401(a) of the Code without notice to and approval by
      the Internal Revenue Service;

            (ii) no plan listed in Schedule 5.19 subject to the provisions of
      Title IV of ERISA has been terminated;

            (iii) there have been no "reportable events" (as that phrase is
      defined in Section 4043 of ERISA) with respect to any such plan listed in
      Schedule 5.19;

            (iv) the Company (including any subsidiaries) has not incurred
      liability under Section 4062 of ERISA; and

            (v) to the knowledge of the Company and the Stockholders, no
      circumstances exist pursuant to which the Company would be reasonably
      likely to have any direct or indirect liability whatsoever (including, but
      not limited to, any liability to any multiemployer plan or the PBGC under
      Title IV of ERISA or to the Internal Revenue Service for any excise tax or
      penalty, or being subject to any statutory lien to secure payment of any
      such liability) with respect to any plan now or heretofore maintained or
      contributed to by any entity other than the Company that is, or at any
      time was, a member of a "controlled group" (as defined in Section
      412(n)(6)(B) of the Code) that includes the Company.

      7.7 NOTIFICATION OF CERTAIN MATTERS BY THE STOCKHOLDERS AND THE COMPANY.
The Stockholders and the Company shall give prompt notice to Pentacon of (i) the
occurrence or non-occurrence of any event the occurrence or nonoccurrence of
which would be likely to cause any representation or warranty of the Company or
the Stockholders contained herein to be untrue or inaccurate in any material
respect at or prior to the Closing and (ii) any material failure of any
Stockholder or the Company to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by such person hereunder. Pentacon
and Newco shall give prompt notice to the Company of (i) the occurrence or
non-occurrence of any event the occurrence or non-occurrence of which would be
likely to cause any representation or warranty of Pentacon or Newco contained
herein to be untrue or inaccurate in any material respect at or prior to the
Closing and (ii) any material failure of Pentacon or Newco to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder. The delivery or deemed delivery of any notice pursuant to this
Section 7.7 shall not be deemed to (i) modify the representations or warranties
hereunder of the party delivering such notice, which modification may only be
made pursuant to Section 7.8, (ii) modify the conditions set forth in Sections 8

exceed the Indemnification Threshold), then Pentacon shall promptly advise the
affected Stockholder(s), in writing, of such potential claim and provide
information supporting the basis and potential amount of such claim (a
"Potential Claim Notice"). This procedure with respect to Potential Claim
Notices is intended to afford the affected Stockholder(s) notice so that it may
attempt to cure or otherwise address the claim prior to Closing; provided,
however, that (i) this procedure shall not affect or delay Closing and (ii)
neither the failure or delay by Pentacon to give a Potential Claim Notice nor
the information included or omitted from a Potential Claim Notice shall
constitute a waiver of, or shall otherwise adversely affect the right to

                                     -33-
<PAGE>
receive indemnification for, any such claim paid by Pentacon, Newco, the
Surviving Corporation or the Company hereunder after the Closing Date.

      7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect to
the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the Company that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect with respect to the Company
may be made unless Pentacon and a majority of the Founding Companies other than
the Company consent to such amendment or supplement; and provided further, that
no amendment or supplement to a Schedule prepared by Pentacon or Newco that
constitutes or reflects an event or occurrence that would have a Material
Adverse Effect with respect to Pentacon or Newco may be made unless a majority
of the Founding Companies consent to such amendment or supplement. For all
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other
Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of the Other Agreements, and such amendment or supplement constitutes
or reflects an event or occurrence that would have a Material Adverse Effect on
such Other Founding Company, Pentacon shall give the Company written notice
promptly after it has knowledge thereof. If Pentacon and a majority of the
Founding Companies consent to such amendment or supplement, which consent shall
have been deemed given by Pentacon or any Founding Company if no response is
received within 24 hours following receipt of written notice of such amendment
or supplement (or sooner if reasonable and if required by the circumstances
under which such consent is requested), but the Company does not give its
consent, the Company may terminate this Agreement pursuant to Section 12.1(iv)
hereof. In the event that the Company seeks to amend or supplement a Schedule
pursuant to this Section 7.8, and Pentacon and a majority of the Other Founding
Companies do not consent to such amendment or supplement, this Agreement shall
be deemed terminated by mutual consent as set forth in Section 12.1(i) hereof.
In the event that Pentacon or Newco seeks to amend or supplement a Schedule
pursuant to this Section 7.8 and a majority of the Founding Companies do not
consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

information relates solely to the Company or the Stockholders, the Company
represents and warrants as to such information with respect to itself, and each
Stockholder represents and warrants, as to such information with respect to the
Company and himself or herself, severally, but not jointly, that the information
expressly provided for inclusion in the Registration Statement or otherwise
confirmed in writing by such Stockholder will not include an untrue statement of
a material fact or omit to state a material fact required to be stated therein

unaudited consolidated balance sheets of the Company as of the end of all fiscal

such financial statements will present fairly the results of operations of the
Company for the periods indicated therein.

the opinion contemplated by Section 8.12 hereof.

Company or the Stockholders become aware of any fact or circumstance which would
materially affect the accuracy of a representation or warranty of Company or
Stockholders in this Agreement, the Company and the Stockholders shall promptly
give notice of such fact or circumstance to Pentacon. However, subject to the
provisions of Section 7.8, such notification shall not relieve either the

Pentacon, the truth and accuracy of any and all warranties and representations
of the Company, or on behalf of the Company and of Stockholders at the date of

11.   INDEMNIFICATION

      The Stockholders, Pentacon and Newco each make the following covenants
that are applicable to them, respectively:

      11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS. The Stockholders
covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless Pentacon, Newco, the Company and the Surviving
Corporation at all times, from and after the date of this Agreement until the
Expiration Date (provided that for purposes of Section 11.1(iii) below, the
Expiration Date shall be the date on which the applicable statute of limitations
expires), from and against all claims, damages, actions, suits, proceedings,
demands, assessments, adjustments, costs and expenses (including specifically,
but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by Pentacon, Newco, the Company or the Surviving
Corporation as a result of or arising from (i) any breach of the representations
and warranties of the Stockholders or the Company set forth herein or on the
definitive, final schedules or certificates delivered by them in connection
herewith, (ii) any breach of any agreement on the part of the Stockholders or,
prior to Closing, the Company under this Agreement, or (iii) any liability under
the 1933 Act, the 1934 Act or other Federal or state law or regulation, at
common law or otherwise, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact relating to the Company or the
Stockholders, and provided in writing to Pentacon or its counsel by the Company
or the Stockholders for inclusion in the Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact relating to the Company or the Stockholders
required to be stated therein or necessary to make the statements therein not
misleading, provided, however, that such indemnity shall not inure to the
benefit of Pentacon, Newco, the Company or the Surviving Corporation to the
extent that such untrue statement (or alleged untrue statement) was made in, or
omission (or alleged omission) occurred in, any preliminary prospectus and the
Stockholders provided, in writing, corrected information to Pentacon counsel and
to Pentacon for inclusion in the final prospectus, and such information was not
so included or properly delivered, and provided further, that, except as herein
otherwise provided, no Stockholder shall be liable for any indemnification
obligation pursuant to this Section 11.1(iii) to the extent attributable to a
breach of any representation, warranty or agreement made herein individually by
any other Stockholder.

      Pentacon and Newco acknowledge and agree that other than the
representations and warranties of Company or Stockholders specifically contained
in this Agreement, there are no representations or warranties of Company or
Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

      Pentacon, Newco and the Company further acknowledge and agree that, should
the Closing occur, their sole and exclusive remedy with respect to any and all
claims relating to this Agreement and the transactions contemplated in this
Agreement, shall be pursuant to the indemnification provisions set forth in this
Section 11.1. Pentacon, Newco and the Company hereby waive, from

                                     -43-
<PAGE>
and after the Closing, to the fullest extent permitted under applicable law, any
and all rights, claims and causes of action they or any indemnified person may
have against the Company or any Stockholder relating to this Agreement or the
transactions contemplated hereby arising under or based upon any federal, state,
local or foreign statute, law, rule, regulation or otherwise (and other than
pursuant to the terms of this Agreement).

      11.2 INDEMNIFICATION BY PENTACON. Pentacon covenants and agrees that it
will indemnify, defend, protect and hold harmless the Stockholders at all times
from and after the date of this Agreement until the Expiration Date, from and
against all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
Stockholders as a result of or arising from (i) any breach by Pentacon or Newco
of their representations and warranties set forth herein or on the definitive,
final schedules or certificates attached delivered by them pursuant hereto, (ii)
any breach of any agreement on the part of Pentacon or Newco under this
Agreement or any other agreement delivered pursuant hereto, (iii) any
liabilities which the Stockholders may incur due to Pentacon's or Newco's or the
Surviving Corporation's failure to pay, perform or discharge when due any of the
liabilities and obligations of the Company for which Pentacon, Newco or the
Surviving Corporation is responsible pursuant to this Agreement (except to the
extent that Pentacon or Newco has bona fide claims hereunder against the
Stockholders by reason of such liabilities); or (iv) any liability under the
1933 Act, the 1934 Act or other Federal or state law or regulation, at common
law or otherwise, arising out of or based upon any untrue statement or alleged
untrue statement of a material fact relating to Pentacon, Newco or any of the
Other Founding Companies contained in any preliminary prospectus, the
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to
Pentacon or Newco or any of the Other Founding Companies required to be stated
therein or necessary to make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has actual knowledge of any claim
by a Person (including a governmental agency) not a party to this Agreement
("Third Person"), or the commencement of any action or proceeding by a Third
Person, with respect to which the Indemnified Person would be entitled to
receive indemnification pursuant to Section 11, the Indemnified Party shall, as
a condition precedent to a claim with respect thereto being made against any
party obligated to provide indemnification pursuant to Section 11.1 or 11.2
hereof (hereinafter the "Indemnifying Party"), give the Indemnifying Party
written notice of such claim or the commencement of such action or proceeding.
Such notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the

                                     -44-
<PAGE>
defense thereof and in any settlement thereof. Such cooperation shall include,
but shall not be limited to, furnishing the Indemnifying Party with any books,
records or information reasonably requested by the Indemnifying Party that are
in the Indemnified Party's possession or control. All Indemnified Parties shall
use the same counsel, which shall be the counsel selected by Indemnifying Party,
provided that if counsel to the Indemnifying Party shall have a conflict of
interest that prevents counsel for the Indemnifying Party from representing
Indemnified Party, Indemnified Party shall have the right to participate in such
matter through counsel of its own choosing and Indemnifying Party will reimburse
the Indemnified Party for the reasonable expenses of its counsel. After the
Indemnifying Party has notified the Indemnified Party of its intention to
undertake to defend or settle any such asserted liability, and for so long as
the Indemnifying Party diligently pursues such defense through appropriate
proceedings, the Indemnifying Party shall not be liable for any additional legal
expenses incurred by the Indemnified Party in connection with any defense or
settlement of such asserted liability, except (i) as set forth in the preceding
sentence and (ii) to the extent such participation is requested by the
Indemnifying Party, in which event the Indemnified Party shall be reimbursed by
the Indemnifying Party for reasonable additional legal expenses and
out-of-pocket expenses. If the Indemnifying Party desires to accept a final and
complete settlement of any such Third Person claim and the Indemnified Party
refuses to consent to such settlement, then the Indemnifying Party's liability
under this Section with respect to such Third Person claim shall be limited to
the amount so offered in settlement by said Third Person. Upon agreement as to
such settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to such claim and all additional costs of settlement or judgment.
If the Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. (a) The indemnification provided for in this
Section 11 shall (except as prohibited by ERISA) be the exclusive remedy in any
action seeking damages or any other form of monetary relief brought by any party
to this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case pursuant to Section
14.3 or otherwise, to seek injunctive or other equitable relief (except for
rescission which shall not be available) for a breach or threatened breach of
this Agreement. Any indemnity payment

                                     -45-
<PAGE>
under this Section 11 shall be treated as an adjustment to the exchange
consideration for tax purposes unless a final determination (which shall include
the execution of a Form 870-AD or successor form) with respect to the
indemnified party or any of its affiliate causes any such payment not to be
treated as an adjustment to the exchange consideration for U.S. Federal Income
Tax purposes.

            (b) Nothing in this Article 11 shall restrict the Stockholders from
subrogation or seeking reimbursement from third parties other than the Company.

      11.5 LIMITATIONS ON INDEMNIFICATION. Pentacon, Newco, the Surviving
Corporation and the other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall not assert any claim for indemnification hereunder against
the Stockholders after the applicable Expiration Date and in no event until such
time as, and solely to the extent that, the aggregate of all claims which such
persons may have against the Stockholders shall exceed the greater of 1% of the
sum of the value of the total consideration (including stock and cash) received
by the Stockholders and Other Stockholders from the Merger or $100,000 (the
"Indemnification Threshold"), and then only to the extent of the excess over the
Indemnification Threshold. Stockholders shall not assert any claim for
indemnification hereunder against Pentacon or Newco after the applicable
Expiration Date and in no event until such time as, and solely to the extent
that, the aggregate of all claims which Stockholders may have against Pentacon
or Newco shall exceed the Indemnification Threshold, and then only to the extent
of the excess over the Indemnification Threshold.

      The Indemnification Threshold and the other limitations contained in this
Section 11.5 shall not be applicable to any breach of covenants made by the
Stockholders in this Agreement which require an action or inaction by such
Stockholders from and after the Closing Date (i.e., Article 10, Article 11,
Article 13, Article 14, Article 17 and Sections 18.1 and 18.6). No person shall
be entitled to indemnification under this Section 11 if, and only to the extent
that such person's claim for indemnification is directly related to a breach by
such person of any representation, warranty, covenant or other agreement set
forth in this Agreement.

      The pursuit by Pentacon, the Surviving Corporation, Newco or the Company,
of any claim for indemnification hereunder against a Stockholder shall require a
majority vote of the board of directors of Pentacon excluding for the purposes
of such acts any directors who was previously a stockholder of the Company or is
a representative of the stockholders of the Company as existing prior to the
closing of the transactions contemplated at this Agreement.

      Notwithstanding any other term of this Agreement, no Stockholder shall be
liable (in the aggregate from time to time taking into account all
indemnification payments made hereunder) under this Section 11 (i) for any
amount which is less than or equal to the Indemnification Threshold (and then
only to the extent of the excess over the Indemnification Threshold) or (ii) for
any amount which exceeds the sum of the amount of proceeds (including cash and
stock) received by the Stockholders and Other Stockholders in connection with
the Merger. Each Stockholder shall have the option of satisfying his or her
indemnity obligation in cash and/or by returning or transferring shares of
Pentacon Stock to Pentacon or any other Indemnified Party. For purposes of
calculating

                                     -46-
<PAGE>
the value of the Pentacon Stock received by a Stockholder and satisfying any
indemnity claim by returning or transferring Pentacon Stock, Pentacon Stock
shall be valued at its initial public offering price as set forth in the
Registration Statement.

      Notwithstanding any of the foregoing provisions of this Section 11 that
might be read to the contrary, it is the agreement of the parties that the
Indemnification Threshold be given full effect under all circumstances.
Accordingly, insofar as any of the foregoing provisions of this Section 11 may
hold harmless an Indemnified Party before the Indemnification Threshold has been
met, then Pentacon and the Stockholders shall cooperate in good faith to
establish an equitable procedure pursuant to which Pentacon reimburses or causes
the reimbursement to the affected Stockholder(s) of all expenditures and
payments by Stockholders that are intended to be absorbed and borne by any
Indemnified Parties as a result of the prior application of the Indemnification
Threshold or otherwise takes such action as may be reasonably necessary to give
effect to the Indemnification Threshold.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION. This Agreement may be terminated at any time prior to
the Consummation Date solely:

            (i) by mutual consent of the boards of directors of Pentacon and the
      Company;

            (ii) by the Stockholders or the Company (acting through its board of
      directors), on the one hand, or by Pentacon (acting through its board of
      directors), on the other hand, if the transactions contemplated by this
      Agreement to take place at the Closing shall not have been consummated by
      February 28, 1998, unless the failure of such transactions to be
      consummated is due to the willful failure of the party seeking to
      terminate this Agreement to perform any of its obligations under this
      Agreement to the extent required to be performed by it prior to or on the
      Consummation Date;

            (iii) by the Stockholders or Company, on the one hand, or by
      Pentacon, on the other hand, if a material breach or default shall be made
      by the other party in the observance or in the due and timely performance
      of any of the covenants or agreements contained herein, and the curing of
      such default shall not have been made on or before the Consummation Date
      or by the Stockholders or the Company, if the conditions set forth in
      Section 8 hereof have not been satisfied or waived as of the Closing Date
      or the Consummation Date, as applicable, or by Pentacon, if the conditions
      set forth in Section 9 hereof have not been satisfied or waived as of the
      Closing Date or the Consummation Date, as applicable;

            (iv)  pursuant to Section 7.8 hereof;

            (v) pursuant to the termination provisions contained in Section 4
      hereof; or

            (vi) pursuant to the other express terms of this Agreement.

                                     -47-
<PAGE>
      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The Stockholders will not, for a period of
five (5) years following the Consummation Date, for any reason whatsoever,
directly or indirectly, for themselves or on behalf of or in conjunction with
any other person, persons, company, partnership, corporation or business of
whatever nature:

            (i) except as disclosed in Section 13.1, engage, as an officer,
      director, shareholder, owner, partner, joint venturer, or in a managerial
      capacity, whether as an employee, independent contractor, consultant or
      advisor, or as a sales representative, in any fastener business or
      operation or related services business in direct competition with Pentacon
      or any of the subsidiaries thereof, within 100 miles of where the Company
      or any of its subsidiaries conducted business prior to the effectiveness
      of the Merger (the "Territory");

            (ii) except with the prior written consent of Pentacon, call upon
      any person who is, at that time, within the Territory, an employee of
      Pentacon or any subsidiary thereof for the purpose or with the intent of
      enticing such employee away from or out of the employ of Pentacon or any
      subsidiary thereof;

            (iii) call upon any person or entity which is, at that time, or
      which has been, within one (1) year prior to the Consummation Date, a
      customer of Pentacon or any subsidiary thereof, of the Company or of any
      of the Other Founding Companies within the Territory for the purpose of
      soliciting or selling products or services that are in direct competition
      with Pentacon within the Territory;

            (iv) call upon any prospective acquisition candidate, on any
      Stockholder's own behalf or on behalf of any competitor in the fastener
      business, which candidate, to the actual knowledge of such Stockholder
      after due inquiry, was called upon by Pentacon or any subsidiary thereof
      or for which, to the actual knowledge of such Stockholder after due
      inquiry, Pentacon or any subsidiary thereof made an acquisition analysis,
      for the purpose of acquiring such entity; or

            (v) disclose customers, whether in existence or proposed, of the
      Company to any person, firm, partnership, corporation or business for any
      reason or purpose relating to the 

                                     -48-
<PAGE>
      fastener business except to the extent that the Company has in the past
      disclosed such information to the public for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any Stockholder from acquiring as a passive investment not more than
one percent (1%) of the capital stock of a competing business whose stock is
traded on a national securities exchange or over-the counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
Pentacon as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to Pentacon for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by Pentacon in the event of breach by such Stockholder,
by injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
Stockholders in light of the activities and business of Pentacon and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of Pentacon; but it is also the intent of Pentacon and the
Stockholders that such covenants be construed and enforced in accordance with
the changing activities; business and locations of Pentacon and its subsidiaries
throughout the term of this covenant. During the term of this covenant, if
Pentacon or one of its subsidiaries engages in new and different activities,
enters a new business or establishes new locations for its current activities or
business in addition to or other than the activities or business it is currently
conducting in the locations currently established therefor, then the
Stockholders will be precluded from soliciting the customers or employees of
such new activities or business or from such new location and from directly
competing with such new activities or business within 100 miles of its
then-established operating location(s) through the term of this covenant.

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any Stockholder
against Pentacon or any subsidiary thereof, whether predicated on this Agreement
or otherwise (except for a claim or cause of action based upon Pentacon's
failure to pay or otherwise tender any of the consideration due to the
Stockholders hereunder), shall not constitute a defense to the enforcement by
Pentacon of such covenants. It is specifically agreed that the period of five
(5) years stated at the beginning of this Section 13, during which the
agreements and covenants of each Stockholder made in this Section 13 shall be
effective, 

                                     -49-
<PAGE>
shall be computed by excluding from such computation any time during which such
Stockholder is in violation of any provision of this Section 13. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The Company and the Stockholders hereby agree that this
covenant is a material and substantial part of this transaction.

14.   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1 STOCKHOLDERS. The Stockholders recognize and acknowledge that they
had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the Company, the Other Founding Companies,
and/or Pentacon, such as operational policies, and pricing and cost policies
that are valuable, special and unique assets of the Company's, the Other
Founding Companies' and/or Pentacon's respective businesses. The Stockholders
agree that they will not disclose such confidential information to any person,
firm, corporation, association or other entity for any purpose or reason
whatsoever, except (a) to authorized representatives of Pentacon, (b) following
the Closing, such information may be disclosed by the Stockholders as is
required in the course of performing their duties for Pentacon or the Surviving
Corporation and (c) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, unless (i) such information becomes known to the public generally through
no fault of the Stockholders, (ii) disclosure is required by law or the order of
any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), the Stockholders shall,
if possible, give prior written notice thereof to Pentacon and provide Pentacon
with the opportunity to contest such disclosure, or (iii) the disclosing party
reasonably believes that such disclosure is required in connection with the
defense of a lawsuit against the disclosing party. In the event of a breach or
threatened breach by any of the Stockholders of the provisions of this Section,
Pentacon shall be entitled to an injunction restraining such Stockholders from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting Pentacon from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.
In the event the transactions contemplated by this Agreement are not
consummated, Stockholders shall have none of the above-mentioned restrictions on
their ability to disseminate confidential information with respect to the
Company.

      14.2 PENTACON AND NEWCO. Pentacon and Newco recognize and acknowledge that
they had in the past and currently have access to certain confidential
information of the Company, including, but not limited to, customer and prospect
lists, financial information, operational policies, and pricing and cost
policies that are valuable, special and unique assets of the Company's business.
Pentacon and Newco agree that, prior to the Consummation Date, or if the
transactions contemplated by this Agreement are not consummated, they will not,
appropriate or make use of any such information, whether for its own benefit or
the benefit of any other person or entity, for any purpose whatsoever (except
pending the Consummation Date, effecting the transactions contemplated hereby)
disclose such confidential information to any person, firm, corporation,
association or other entity 

                                     -50-
<PAGE>
for any purpose or reason whatsoever, except (a) to authorized representatives
of the Company, (b) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.2, (c) to the Other Founding Companies and their representatives pursuant to
Section 7.1(a), unless (i) such information becomes known to the public
generally through no fault of Pentacon or Newco, (ii) disclosure is required by
law or the order of any governmental authority under color of law, provided,
that prior to disclosing any information pursuant to this clause (ii), Pentacon
and Newco shall, if possible, give prior written notice thereof to the Company
and the Stockholders and provide the Company and the Stockholders with the
opportunity to contest such disclosure, or (iii) the disclosing party reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit against the disclosing party, and (d) to the public to the extent
necessary or advisable in connection with the filing of the Registration
Statement and the IPO and the securities laws applicable thereto and to the
operation of Pentacon as a publicly held entity after the IPO. In the event of a
breach or threatened breach by Pentacon or Newco of the provisions of this
Section, the Company and the Stockholders shall be entitled to an injunction
restraining Pentacon and Newco from disclosing, in whole or in part, such
confidential information. Nothing herein shall be construed as prohibiting the
Company and the Stockholders from pursuing any other available remedy for such
breach or threatened breach, including the recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach or threatened breach by any of them of the foregoing
covenants, the covenant may be enforced against the other parties by injunctions
and restraining orders or other appropriate equitable relief, without posting
any bond or other security or having to prove irreparable harm or injury.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Consummation Date, or without limitation if the transactions contemplated hereby
are not consummated.

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Unless otherwise agreed by Pentacon, except
for transfers to immediate family members who agree to be bound by the
restrictions set forth in this Section 15.1 (or trusts or partnerships for the
benefit of charities, the Stockholders or Other Stockholders, family members,
the trustees or partners of which so agree), for a period of one year from the
Closing, except pursuant to Section 17 hereof, none of the Stockholders or Other
Stockholders shall sell, assign, exchange, transfer, encumber, pledge,
distribute, appoint, or otherwise dispose of any shares of Pentacon Stock
received by the Stockholders or Other Stockholders in the Merger. The
certificates evidencing the Pentacon Stock delivered to the Stockholders or
Other Stockholders pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as Pentacon may deem necessary or appropriate:

                                     -51-
<PAGE>
THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED
OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT
OR OTHER DISPOSITION PRIOR TO FIRST ANNIVERSARY OF CLOSING DATE. UPON THE
WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE
THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT)
AFTER THE DATE SPECIFIED ABOVE.

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The Stockholders acknowledge that the shares of
Pentacon Stock to be delivered to the Stockholders and Other Stockholders
pursuant to this Agreement have not been and will not be registered under the
1933 Act (except as provided in Section 17 hereof) and therefore may not be
resold without compliance with the 1933 Act. The Pentacon Stock to be acquired
by such Stockholders and Other Stockholders pursuant to this Agreement is being
acquired solely for their own respective accounts, for investment purposes only,
and with no present intention of distributing, selling or otherwise disposing of
it in connection with a distribution. The Stockholders covenant, warrant and
represent that none of the shares of Pentacon Stock issued to such Stockholders
and Other Stockholders will be offered, sold, assigned, pledged, hypothecated,
transferred or otherwise disposed of except after full compliance with all of
the applicable provisions of the 1933 Act and the rules and regulations of the
SEC. All the Pentacon Stock shall bear the following legend in addition to the
legend required under Section 15 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The Stockholders are able to bear the
economic risk of an investment in the Pentacon Stock to be acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment in the
Pentacon Stock. The Stockholders party hereto have had an adequate opportunity
to ask questions and receive answers from the officers of Pentacon concerning
any and all matters relating to the transactions described herein including,
without limitation, the background and experience of the current and proposed
officers and directors of Pentacon, the plans for the operations of the business
of Pentacon, the business, operations and financial condition of the Founding
Companies other than the Company, and any plans for additional acquisitions and
the like. The Stockholders have asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

                                     -52-

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever Pentacon proposes to register any Pentacon Stock for its own or others
account under the 1933 Act for a public offering, other than (i) any shelf or
other registration of shares to be used as consideration for acquisitions of
additional businesses by Pentacon and (ii) registrations relating to employee
benefit plans, Pentacon shall give each of the Stockholders and Other
Stockholders prompt written notice of its intent to do so. Upon the written
request of any of the Stockholders or Other Stockholders given within 30 days
after receipt of such notice, Pentacon shall cause to be included in such
registration all of the Pentacon Stock issued to the Stockholders or Other
Stockholders pursuant to this Agreement (including any stock issued as (or
issuable upon the conversion or exchange of any convertible security, warrant,
right or other security which is issued by Pentacon as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such
Pentacon Stock) which any such Stockholder or Other Stockholder requests,
provided that Pentacon shall have the right to reduce the number of shares
included in such registration to the extent that inclusion of such shares would,
in the written opinion of tax counsel to Pentacon or its independent auditors,
reasonably be likely to jeopardize the status of the transactions contemplated
hereby and by the Registration Statement as a tax-free organization under
Section 351 of the Code. In addition, if Pentacon is advised in writing in good
faith by any managing underwriter of an underwritten offering of the securities
being offered pursuant to any registration statement under this Section 17.1
that the number of shares to be sold by persons other than Pentacon is greater
than the number of such shares which can be offered without adversely affecting
the offering, Pentacon may reduce pro rata the number of shares offered for the
accounts of such persons (based upon the number of shares held by such person)
to a number deemed satisfactory by such managing underwriter, provided, that,
for each such offering made by Pentacon after the IPO, such reduction shall be
made first by reducing the number of shares to be sold by persons other than
Pentacon, the Stockholders or Other Stockholders and the Stockholders of the
Other Founding Companies (collectively, the Stockholders, Other Stockholders and
the Stockholders of the other Founding Companies being referred to herein as the
"Founding Stockholders"), and thereafter, if a further reduction is required, by
reducing the number of shares to be sold by the Founding Stockholders.

      17.2 REGISTRATION PROCEDURES. Whenever Pentacon is required to register
shares of Pentacon Stock pursuant to Section 17.1, Pentacon will, as
expeditiously as possible:

            (i) Prepare and file with the SEC a registration statement with
      respect to such shares and use its best efforts to cause such registration
      statement to become effective (provided that before filing a registration
      statement or prospectus or any amendments or supplements or term sheets
      thereto, Pentacon will furnish a representative of the Stockholders or
      Other Stockholders with copies of all such documents proposed to be filed)
      as promptly as practical;

                                     -53-
<PAGE>
            (ii) Prepare and file with the SEC such amendments and supplements
      to such registration statement and the prospectus used in connection
      therewith as may be necessary to keep such registration statement
      effective for a period of not less than 120 days;

            (iii) Furnish to each Stockholder or Other Stockholder who so
      requests such number of copies of such registration statement, each
      amendment and supplement thereto and the prospectus included in such
      registration statement (including each preliminary prospectus and any term
      sheet associated therewith), and such other documents as such Stockholder
      or Other Stockholder may reasonably request in order to facilitate the
      disposition of the relevant shares;

            (iv) Use its best efforts to register or qualify the securities
      covered by such registration statement under such other securities or Blue
      Sky laws of such jurisdictions as shall be reasonably requested by the
      Stockholders or Other Stockholders, and to keep such registration or
      qualification effective during the period such registration statement is
      to be kept effective, provided that Pentacon shall not be required to
      become subject to taxation, to qualify to do business or to file a general
      consent to service of process in any such states or jurisdictions;

            (v) Cause all such shares of Pentacon Stock to be listed or included
      on any securities exchanges or trading systems on which similar securities
      issued by Pentacon are then listed or included;

            (vi) Notify each Stockholder or Other Stockholder at any time when a
      prospectus relating thereto is required to be delivered under the 1933 Act
      within the period that Pentacon is required to keep the registration
      statement effective of the happening of any event as a result of which the
      prospectus included in such registration statement, together with any
      associated term sheet, contains an untrue statement of a material fact or
      omits any fact necessary to make the statement therein not misleading,
      and, at the request of such Stockholder or Other Stockholder, Pentacon
      will prepare a supplement or amendment to such prospectus so that, as
      thereafter delivered to the purchasers of the covered shares, such
      prospectus will not contain an untrue statement of material fact or omit
      to state any fact necessary to make the statements therein not misleading.

      All expenses incurred in connection with the registration under this
Article 17 (including all registration, filing, qualification, legal, printer
and accounting fees, but excluding underwriting commissions and discounts),
shall be borne by Pentacon.

      17.3  INDEMNIFICATION.

            (a) In connection with any registration hereunder, Pentacon shall
indemnify, to the extent permitted by law, each Stockholder and Other
Stockholders against all losses, claims, damages, liabilities and expenses
arising out of or resulting from any untrue or alleged untrue

                                     -54-
<PAGE>
statement of material fact contained in any registration statement, prospectus
or preliminary prospectus or associated term sheet or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading except insofar as the
same are caused by or contained in or omitted from any information furnished in
writing to Pentacon by such indemnified party expressly for use therein or by
any indemnified parties' failure to deliver a copy of the registration statement
or prospectus or any amendment or supplements thereto after Pentacon has
furnished such Indemnified Party with a sufficient number of copies of the same.

            (b) In connection with any registration hereunder, each Stockholder
shall furnish to Pentacon in writing such information as is reasonably requested
by Pentacon for use in any such registration statement or prospectus and will
indemnify, to the extent permitted by law, Pentacon, its directors and officers
and each person who controls Pentacon (within the meaning of the 1933 Act)
against any losses, claims, damages, liabilities and expenses resulting from any
untrue or alleged untrue statement or material fact or any omission or alleged
omission of a material fact required to be stated in the registration statement
or prospectus or any amendment thereof or supplement thereto necessary to make
the statements therein not misleading, but only to the extent that such untrue
statement or omission is contained in information so furnished in writing by
such Stockholder specifically for use in preparing the registration statement.
Notwithstanding the foregoing, the liability of a Stockholder under this Section
17.3 shall be limited to an amount equal to the net proceeds actually received
by such Stockholder from the sale of the relevant shares covered by the
registration statement.

            (c) Any person entitled to indemnification under this Section will
(i) give prompt notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified parties'
reasonable judgment, a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. Any failure to give prompt notice shall
deprive a party of its right to indemnification hereunder only to the extent
that such failure shall have adversely affected the indemnifying party. If the
defense of any claim is assumed, the indemnifying party will not be subject to
any liability for any settlement made without its consent (but such consent
shall not be unreasonably withheld). An indemnifying party who is not entitled
or elects not to assume the defense of a claim, will not be obligated to pay the
fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party, a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Section 17.1 covering an underwritten registered offering, Pentacon and each
participating holder agree to enter into a written agreement with the managing
underwriters in such form and containing such provisions as are customary in the
securities business for such an arrangement between such

                                     -55-
<PAGE>
managing underwriters and companies of Pentacon's size and investment stature,
including indemnification.

      17.5 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of Pentacon
stock to the public without registration, Pentacon agrees to use its
commercially reasonable efforts to:

            (i) make and keep public information regarding Pentacon available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of Pentacon under the 1933 Act and the 1934 Act at any
      time after it has become subject to such reporting requirements; and

            (iii) so long as a Stockholder or Other Stockholder owns any
      restricted Pentacon Common Stock, furnish to each Stockholder or Other
      Stockholder forthwith upon written request a written statement by Pentacon
      as to its compliance with the reporting requirements of Rule 144 (at any
      time from and after 90 days following the effective date of the
      Registration Statement, and of the 1933 Act and the 1934 Act (any time
      after it has become subject to such reporting requirements), a copy of the
      most recent annual or quarterly report of Pentacon, and such other reports
      and documents so filed as a Stockholder or Other Stockholder may
      reasonably request in availing itself of any rule or regulation of the SEC
      allowing a Stockholder or Other Stockholder to sell any such shares
      without registration.

18.   GENERAL

      18.1 COOPERATION. The Company, Stockholders, Pentacon and Newco shall each
deliver or cause to be delivered to the other on the Consummation Date, and at
such other times and places as shall be reasonably agreed to, such additional
instruments as the other may reasonably request for the purpose of carrying out
this Agreement. The Company will cooperate and use its reasonable efforts to
have the present officers, directors and employees of the Company cooperate with
Pentacon on and after the Consummation Date in furnishing information, evidence,
testimony and other assistance in connection with any tax return filing
obligations, actions, proceedings, arrangements or disputes of any nature with
respect to matters pertaining to all periods prior to the Consummation Date.

      18.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the parties

      18.3 ENTIRE AGREEMENT. This Agreement (including the schedules, exhibits
and annexes attached hereto) and the documents delivered pursuant hereto
constitute the entire agreement and understanding among the Stockholders, the
Company, Newco and Pentacon and supersede any prior agreement and understanding
relating to the subject matter of this Agreement. This Agreement, upon
execution, constitutes a valid and binding agreement of the parties hereto
enforceable in accordance with its terms and may be modified or amended only (i)
pursuant to Section 7.8 with respect to the amendment of Schedules or (ii) by a
written instrument executed by the Stockholders, the Company, Newco and
Pentacon, acting through their respective officers or trustees, duly authorized
by their respective Boards of Directors. Any disclosure made on any Schedule
delivered pursuant hereto shall be deemed to have been disclosed for purposes of
any other Schedule required hereby, provided that the Company shall make a good
faith effort to cross reference disclosure, as necessary or advisable, between
related Schedules, and provided further that the failure to do so will not
affect the validity of such disclosure.

      18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

      18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each party
represents and warrants that it employed no broker or agent in connection with
this transaction and agrees to indemnify the other parties hereto against all
loss, cost, damages or expense arising out of claims for fees or commission of
brokers employed or alleged to have been employed by such indemnifying party.

      18.6 EXPENSES. Whether or not the transactions herein contemplated shall
be consummated, Pentacon will pay the fees, expenses and disbursements of
Pentacon and its agents, representatives, accountants and counsel incurred in
connection with the subject matter of this Agreement and any amendments thereto,
including all costs and expenses incurred in the performance and compliance with
all conditions to be performed by Pentacon under this Agreement, including the
fees and expenses of Ernst & Young LLP, Andrews & Kurth L.L.P., and any other
person or entity retained by Pentacon or by McFarland, Grossman Capital Ventures
II, L.C., and the costs of preparing the Registration Statement. Except as
agreed in writing by Pentacon, each Stockholder shall pay their respective fees,
expenses and disbursements of counsel and other professionals in connection with
this transaction and shall pay all sales, use, transfer, real property transfer,
recording, gains, stock transfer and other similar taxes and fees ("Transfer
Taxes") imposed in connection with the Merger, other than Transfer Taxes, if
any, imposed by the State of Delaware. Each Stockholder shall file all necessary
documentation and Returns with respect to such Transfer Taxes. In addition, each
Stockholder acknowledges that he, and not the Company or Pentacon, will pay all
taxes due upon receipt of the consideration payable pursuant to Section 2
hereof. The Stockholders acknowledge that the risks of the transactions
contemplated hereby include tax risks, with respect to which the Stockholders
are relying solely on the opinion contemplated by Section 8.12 hereof.

      7.7 NOTIFICATION OF CERTAIN MATTERS BY THE STOCKHOLDERS AND THE COMPANY.
The Stockholders and the Company shall give prompt notice to Pentacon of (i) the
occurrence or non-occurrence of any event the occurrence or nonoccurrence of
which would be likely to cause any representation or warranty of the Company or
the Stockholders contained herein to be untrue or inaccurate in any material
respect at or prior to the Closing and (ii) any material failure of any
Stockholder or the Company to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by such person hereunder. Pentacon
and Newco shall give prompt notice to the Company of (i) the occurrence or
non-occurrence of any event the occurrence or non-occurrence of which would be
likely to cause any representation or warranty of Pentacon or Newco contained
herein to be untrue or inaccurate in any material respect at or prior to the
Closing and (ii) any material failure of Pentacon or Newco to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder. The delivery or deemed delivery of any notice pursuant to this
Section 7.7 shall not be deemed to (i) modify the representations or warranties

                                      -32-
<PAGE>
hereunder of the party delivering such notice, which modification may only be
made pursuant to Section 7.8, (ii) modify the conditions set forth in Sections 8
and 9, or (iii) limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

      If, prior to the Closing Date, the Chief Executive Officer, the Chief
Financial Officer or the General Counsel of Pentacon shall determine that any of
Pentacon, Newco, the Surviving Corporation or the Company has a claim hereunder
for indemnification against any Stockholder(s) (whether or not such claim might
exceed the Indemnification Threshold), then Pentacon shall promptly advise the
affected Stockholder(s), in writing, of such potential claim and provide
information supporting the basis and potential amount of such claim (a
"Potential Claim Notice"). This procedure with respect to Potential Claim
Notices is intended to afford the affected Stockholder(s) notice so that it may
attempt to cure or otherwise address the claim prior to Closing; provided,
however, that (i) this procedure shall not affect or delay Closing and (ii)
neither the failure or delay by Pentacon to give a Potential Claim Notice nor
the information included or omitted from a Potential Claim Notice shall
constitute a waiver of, or shall otherwise adversely affect the right to receive
indemnification for, any such claim paid by Pentacon, Newco, the Surviving
Corporation or the company hereunder after the Closing Date.

      7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect to
the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the Company that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect with respect to the Company
may be made unless Pentacon and a majority of the Founding Companies other than
the Company consent to such amendment or supplement; and provided further, that
no amendment or supplement to a Schedule prepared by Pentacon or Newco that
constitutes or reflects an event or occurrence that would have a Material
Adverse Effect with respect to Pentacon or Newco may be made unless a majority
of the Founding Companies consent to such amendment or supplement. For all
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other
Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of the Other Agreements, and such amendment or supplement constitutes
or reflects an event or occurrence that would have a Material Adverse Effect on
such Other Founding Company, Pentacon shall give the Company written notice
promptly after it has knowledge thereof. If Pentacon and a majority of the
Founding Companies consent to such amendment or supplement, which consent shall
have been deemed given by Pentacon or any Founding Company if no response is
received within 24 hours

                                      -33-
<PAGE>
following receipt of written notice of such amendment or supplement (or sooner
if reasonable and if required by the circumstances under which such consent is
requested), but the Company does not give its consent, the Company may terminate
this Agreement pursuant to Section 12.1(iv) hereof. In the event that the
Company seeks to amend or supplement a Schedule pursuant to this Section 7.8,
and Pentacon and a majority of the Other Founding Companies do not consent to
such amendment or supplement, this Agreement shall be deemed terminated by
mutual consent as set forth in Section 12.1(i) hereof. In the event that
Pentacon or Newco seeks to amend or supplement a Schedule pursuant to this
Section 7.8 and a majority of the Founding Companies do not consent to such
amendment or supplement, this Agreement shall be deemed terminated by mutual
consent as set forth in Section 12.1(i) hereof. No party to this Agreement shall
be liable to any other party if this Agreement shall be terminated pursuant to
the provisions of this Section 7.8. No amendment of or supplement to a Schedule
shall be made later than 24 hours prior to the anticipated effectiveness of the
Registration Statement.

Stockholders shall furnish or cause to be furnished to Pentacon and the
Underwriters all of the information concerning the Company and the Stockholders
reasonably required for inclusion in, and will cooperate with Pentacon and the
Underwriters in the preparation of, the Registration Statement and the
prospectus included therein (including audited and unaudited financial
statements, prepared in accordance with generally accepted accounting
principles, in form suitable for inclusion in the Registration Statement, except
that the cost of the preparation of any such audited and unaudited Financial

promptly to advise Pentacon if at any time during the period in which a
prospectus relating to the IPO is required to be delivered under the Securities
Act, any information contained in the prospectus concerning the Company or the
Stockholders becomes incorrect or incomplete in any material respect, and to
provide the information needed to correct such inaccuracy. Insofar as the
information relates solely to the Company or the Stockholders, the Company
represents and warrants as to such information with respect to itself, and each
Stockholder represents and warrants, as to such information with respect to the
Company and himself or herself, severally, but not jointly, that the information
expressly provided for inclusion in the Registration Statement or otherwise
confirmed in writing by such Stockholder will 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, in light of the circumstances under
which they were made, not misleading.

      7.10 FINAL FINANCIAL STATEMENTS. The Company shall provide prior to the
Consummation Date, and Pentacon shall have had sufficient time to review the
unaudited consolidated balance sheets of the Company as of the end of all fiscal
quarters following the Balance Sheet Date, and the unaudited consolidated
statement of income, cash flows and retained earnings of the Company for all
fiscal quarters ended after the Balance Sheet Date. Such financial statements
shall have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods indicated
(except as noted therein). Except as noted in such financial statements, all of
such financial statements will present fairly the results of operations of the
Company for the periods indicated therein.

recognize that one or more filings under the Hart-Scott-Rodino Act may be

Hart-Scott-Rodino Act are required, then: (i) each of the parties hereto agrees
to cooperate and use its best efforts to comply with the Hart-Scott-Rodino Act,
(ii) such compliance by the Stockholders and the Company shall be deemed a
condition precedent in addition to the conditions precedent set forth in Section
8 of this Agreement, and such compliance by Pentacon and Newco shall be deemed a
condition precedent in addition to the conditions precedent set forth in Section
9 of this Agreement, and (iii) the parties agree to cooperate and use their best
efforts to cause all filings required under the Hart-Scott-Rodino Act to be
made. If filings under the Hart-Scott-Rodino Act are required, the costs and
expenses thereof (including filing fees) shall be borne by Pentacon. The
obligation of each party to consummate the transactions contemplated by this
Agreement is subject to the expiration or termination of the waiting period
under the Hart-Scott-Rodino Act, if applicable.

      7.14 PRE-CLOSING NOTIFICATIONS. If, prior to the 25th day after the date
of the final prospectus of Pentacon utilized in connection with the IPO, the
Company or the Stockholders become aware of any fact or circumstance which would
materially affect the accuracy of a representation or warranty of Company or
Stockholders in this Agreement, the Company and the Stockholders shall promptly
give notice of such fact or circumstance to Pentacon. However, subject to the
provisions of Section 7.8, such notification shall not relieve either the
Company or the Stockholders of their respective obligations under this
Agreement, and, subject to the provisions of Section 7.8, at the sole option of
Pentacon, the truth and accuracy of any and all warranties and representations
of the Company, or on behalf of the Company and of Stockholders at the date of
this Agreement and on the Closing Date and on the Consummation Date, shall be a
precondition to the consummation of this transaction.

required by applicable law, Pentacon will describe or report the transaction in

consistent with the tax opinion referenced in Section 8.12.

      7.19 PERMITS. Pentacon agrees, prior to the Consummation Date, to obtain

11.   INDEMNIFICATION

      The Stockholders, Pentacon and Newco each make the following covenants
that are applicable to them, respectively:

      11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS. The Stockholders
covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless Pentacon, Newco, the Company and the Surviving
Corporation at all times, from and after the date of this Agreement until the
Expiration Date (provided that for purposes of Section 11.1(iii) below, the
Expiration Date shall be the date on which the applicable statute of limitations
expires), from and against all claims, damages, actions, suits, proceedings,
demands, assessments, adjustments, costs and expenses (including specifically,
but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by Pentacon, Newco, the Company or the Surviving
Corporation as a result of or arising from (i) any breach of the representations
and warranties of the Stockholders or the Company set forth herein or on the
definitive, final schedules or certificates delivered by them in connection
herewith, (ii) any breach of any agreement on the part of the Stockholders or,
prior to Closing, the Company under this Agreement, or (iii) any liability under
the 1933 Act, the 1934 Act or other Federal or state law or regulation, at
common law or otherwise, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact relating to the Company or the
Stockholders, and provided in writing to Pentacon or its counsel by the Company
or the Stockholders for inclusion in the Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, or arising out of or based upon any omission or alleged omission to
state therein a material fact relating to the Company or the Stockholders
required to be stated therein or necessary to make the statements therein not
misleading, provided, however, that such indemnity shall not inure to the
benefit of Pentacon, Newco, the Company or the Surviving Corporation to the
extent that such untrue statement (or alleged untrue statement) was made in, or
omission (or alleged omission) occurred in, any preliminary prospectus and the
Stockholders provided, in writing, corrected information to Pentacon counsel and
to Pentacon for inclusion in the final prospectus, and such information was not
so included or properly delivered, and provided further, that no Stockholder
shall be liable for any indemnification obligation pursuant to this Section
11.1(iii) to the extent attributable to a breach of any representation, warranty
or agreement made herein individually by any other Stockholder.

      Pentacon and Newco acknowledge and agree that other than the
representations and warranties of Company or Stockholders specifically contained
in this Agreement, there are no representations or warranties of Company or
Stockholders, either express or implied, with respect

                                      -42-
<PAGE>
to the transactions contemplated by this Agreement, the Company or its assets, 
liabilities and business.

      Pentacon, Newco and the Company further acknowledge and agree that, should
the Closing occur, their sole and exclusive remedy with respect to any and all
claims relating to this Agreement and the transactions contemplated in this
Agreement, shall be pursuant to the indemnification provisions set forth in this
Section 11.1. Pentacon, Newco and the Company hereby waive, from and after the
Closing, to the fullest extent permitted under applicable law, any and all
rights, claims and causes of action they or any indemnified person may have
against the Company or any Stockholder relating to this Agreement or the
transactions contemplated hereby arising under or based upon any federal, state,
local or foreign statute, law, rule, regulation or otherwise (and other than
pursuant to the terms of this Agreement).

      11.2 INDEMNIFICATION BY PENTACON. Pentacon covenants and agrees that it
will indemnify, defend, protect and hold harmless the Stockholders at all times
from and after the date of this Agreement until the Expiration Date, from and
against all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
Stockholders as a result of or arising from (i) any breach by Pentacon or Newco
of their representations and warranties set forth herein or on the definitive,
final schedules or certificates attached delivered by them pursuant hereto, (ii)
any breach of any agreement on the part of Pentacon or Newco under this
Agreement or any other agreement delivered pursuant hereto, (iii) any
liabilities which the Stockholders may incur due to Pentacon's or Newco's or the
Surviving Corporation's failure to pay, perform or discharge when due any of the
liabilities and obligations of the Company for which Pentacon, Newco or the
Surviving Corporation is responsible pursuant to this Agreement (except to the
extent that Pentacon or Newco has bona fide claims hereunder against the
Stockholders by reason of such liabilities); or (iv) any liability under the
1933 Act, the 1934 Act or other Federal or state law or regulation, at common
law or otherwise, arising out of or based upon any untrue statement or alleged
untrue statement of a material fact relating to Pentacon, Newco or any of the
Other Founding Companies contained in any preliminary prospectus, the
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to
Pentacon or Newco or any of the Other Founding Companies required to be stated
therein or necessary to make the statements therein not misleading.

      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has actual knowledge of any claim
by a Person (including a governmental agency) not a party to this Agreement
("Third Person"), or the commencement of any action or proceeding by a Third
Person, with respect to which the Indemnified Person would be entitled to
receive indemnification pursuant to Section 11, the Indemnified Party shall, as
a condition precedent to a claim with respect thereto being made against any
party obligated to provide indemnification pursuant to Section 11.1 or 11.2
hereof (hereinafter the "Indemnifying Party"), give the Indemnifying Party
written notice of such claim or the commencement of such action or

                                      -43-
<PAGE>
proceeding. Such notice shall state the nature and the basis of such claim and a
reasonable estimate of the amount thereof. The Indemnifying Party shall have the
right to defend and settle, at its own expense and by its own counsel, any such
matter so long as the Indemnifying Party pursues the same in good faith and
diligently, provided that the Indemnifying Party shall not settle any criminal
proceeding without the written consent of the Indemnified Party. If the
Indemnifying Party undertakes to defend or settle, it shall promptly notify the
Indemnified Party of its intention to do so, and the Indemnified Party shall
cooperate with the Indemnifying Party and its counsel in the defense thereof and
in any settlement thereof. Such cooperation shall include, but shall not be
limited to, furnishing the Indemnifying Party with any books, records or
information reasonably requested by the Indemnifying Party that are in the
Indemnified Party's possession or control. All Indemnified Parties shall use the
same counsel, which shall be the counsel selected by Indemnifying Party,
provided that if counsel to the Indemnifying Party shall have a conflict of
interest that prevents counsel for the Indemnifying Party from representing
Indemnified Party, Indemnified Party shall have the right to participate in such
matter through counsel of its own choosing and Indemnifying Party will reimburse
the Indemnified Party for the reasonable expenses of its counsel. After the
Indemnifying Party has notified the Indemnified Party of its intention to
undertake to defend or settle any such asserted liability, and for so long as
the Indemnifying Party diligently pursues such defense through appropriate
proceedings, the Indemnifying Party shall not be liable for any additional legal
expenses incurred by the Indemnified Party in connection with any defense or
settlement of such asserted liability, except (i) as set forth in the preceding
sentence and (ii) to the extent such participation is requested by the
Indemnifying Party, in which event the Indemnified Party shall be reimbursed by
the Indemnifying Party for reasonable additional legal expenses and
out-of-pocket expenses. If the Indemnifying Party desires to accept a final and
complete settlement of any such Third Person claim and the Indemnified Party
refuses to consent to such settlement, then the Indemnifying Party's liability
under this Section with respect to such Third Person claim shall be limited to
the amount so offered in settlement by said Third Person. Upon agreement as to
such settlement between said Third Person and the Indemnifying Party, the
Indemnifying Party shall, in exchange for a complete release from the
Indemnified Party, promptly pay to the Indemnified Party the amount agreed to in
such settlement and the Indemnified Party shall, from that moment on, bear full
responsibility for any additional costs of defense which it subsequently incurs
with respect to such claim and all additional costs of settlement or judgment.
If the Indemnifying Party does not undertake to defend such matter to which the
Indemnified Party is entitled to indemnification hereunder, or fails diligently
to pursue such defense, the Indemnified Party may undertake such defense through
counsel of its choice, at the cost and expense of the Indemnifying Party, and
the Indemnified Party may settle such matter, and the Indemnifying Party shall
reimburse the Indemnified Party for the amount paid in such settlement and any
other liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

                                      -44-
<PAGE>
      11.4 EXCLUSIVE REMEDY. (a) The indemnification provided for in this
Section 11 shall (except as prohibited by ERISA) be the exclusive remedy in any
action seeking damages or any other form of monetary relief brought by any party
to this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case pursuant to Section
14.3 or otherwise, to seek injunctive or other equitable relief (except for
rescission which shall not be available) for a breach or threatened breach of
this Agreement. Any indemnity payment under this Section 11 shall be treated as
an adjustment to the exchange consideration for tax purposes unless a final
determination (which shall include the execution of a Form 870-AD or successor
form) with respect to the indemnified party or any of its affiliate causes any
such payment not to be treated as an adjustment to the exchange consideration
for U.S. Federal Income Tax purposes.

            (b) Nothing in this Article 11 shall restrict the Stockholders from
subrogation or seeking reimbursement from third parties other than the Company.

      11.5 LIMITATIONS ON INDEMNIFICATION. Pentacon, Newco, the Surviving
Corporation and the other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall not assert any claim for indemnification hereunder against
the Stockholders after the applicable Expiration Date and in no event until such
time as, and solely to the extent that, the aggregate of all claims which such
persons may have against the Stockholders shall exceed the greater of 1% of the
value of the total consideration (including stock and cash) received by the
Stockholders from the Merger or $100,000 (the "Indemnification Threshold"), and
then only to the extent of the excess over the Indemnification Threshold.
Stockholders shall not assert any claim for indemnification hereunder against
Pentacon or Newco after the applicable Expiration Date and in no event until
such time as, and solely to the extent that, the aggregate of all claims which
Stockholders may have against Pentacon or Newco shall exceed the Indemnification
Threshold, and then only to the extent of the excess over the Indemnification
Threshold.

      The Indemnification Threshold and the other limitations contained in this
Section 11.5 shall not be applicable to any breach of covenants made by the
Stockholders in this Agreement which require an action or inaction by such
Stockholders from and after the Closing Date (i.e., Article 10, Article 11,
Article 13, Article 14, Article 17 and Sections 18.1 and 18.6). No person shall
be entitled to indemnification under this Section 11 if, and only to the extent
that such person's claim for indemnification is directly related to a breach by
such person of any representation, warranty, covenant or other agreement set
forth in this Agreement.

      The pursuit by Pentacon, the Surviving Corporation, Newco or the Company,
of any claim for indemnification hereunder against a Stockholder shall require a
majority vote of the board of directors of Pentacon excluding for the purposes
of such acts any directors who was previously a stockholder of the Company or is
a representative of the stockholders of the Company as existing prior to the
closing of the transactions contemplated at this Agreement.

      Notwithstanding any other term of this Agreement, no Stockholder shall be
liable (in the aggregate from time to time taking into account all
indemnification payments made hereunder) under

                                      -45-
<PAGE>
Section 11 (i) for any amount which is less than or equal to the Indemnification
Threshold (and then only to the extent of the excess over the Indemnification
Threshold) or (ii) for any amount which exceeds the amount of proceeds
(including cash and stock) received by such Stockholder in connection with the
Merger. Each Stockholder shall have the option of satisfying his or her
indemnity obligation in cash and/or by returning or transferring shares of
Pentacon Stock to Pentacon or any other Indemnified Party. For purposes of
calculating the value of the Pentacon Stock received by a Stockholder and
satisfying any indemnity claim by returning or transferring Pentacon Stock,
Pentacon Stock shall be valued at its initial public offering price as set forth
in the Registration Statement.

      Notwithstanding any of the foregoing provisions of this Section 11 that
might be read to the contrary, it is the agreement of the parties that the
Indemnification Threshold be given full effect under all circumstances.
Accordingly, insofar as any of the foregoing provisions of this Section 11 may
hold harmless an Indemnified Party before the Indemnification Threshold has been
met, then Pentacon and the Stockholders shall cooperate in good faith to
establish an equitable procedure pursuant to which Pentacon reimburses or causes
the reimbursement to the affected Stockholder(s) of all expenditures and
payments by Stockholders that are intended to be absorbed and borne by any
Indemnified Parties as a result of the prior application of the Indemnification
Threshold or otherwise takes such action as may be reasonably necessary to give
effect to the Indemnification Threshold.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION. This Agreement may be terminated at any time prior to
the Consummation Date solely:

            (i)   by mutual consent of the boards of directors of Pentacon and 
      the Company;

      directors), on the one hand, or by Pentacon (acting through its board of
      directors), on the other hand, if the transactions contemplated by this
      Agreement to take place at the Closing shall not have been consummated by
      February 28, 1998, unless the failure of such transactions to be
      consummated is due to the willful failure of the party seeking to
      terminate this Agreement to perform any of its obligations under this
      Agreement to the extent required to be performed by it prior to or on the
      Consummation Date;

            (iii) by the Stockholders or Company, on the one hand, or by
      Pentacon, on the other hand, if a material breach or default shall be made
      by the other party in the observance or in the due and timely performance
      of any of the covenants or agreements contained herein, and the curing of
      such default shall not have been made on or before the Consummation Date
      or by the Stockholders or the Company, if the conditions set forth in
      Section 8 hereof have not been satisfied or waived as of the Closing Date
      or the Consummation Date, as applicable, or by Pentacon, if the conditions
      set forth in Section 9 hereof have not been satisfied or waived as of the
      Closing Date or the Consummation Date, as applicable;

                                      -46-

obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The Stockholders will not, for a period of
five (5) years following the Consummation Date, for any reason whatsoever,
directly or indirectly, for themselves or on behalf of or in conjunction with
any other person, persons, company, partnership, corporation or business of
whatever nature:

            (i) except as disclosed in Schedule 13.1, engage, as an officer,
      director, shareholder, owner, partner, joint venturer, or in a managerial
      capacity, whether as an employee, independent contractor, consultant or
      advisor, or as a sales representative, in any fastener business or
      operation or related services business in direct competition with Pentacon
      or any of the subsidiaries thereof, within 100 miles of where the Company
      or any of its subsidiaries conducted business prior to the effectiveness
      of the Merger (the "Territory");

            (ii) except with the prior written consent of Pentacon, call upon
      any person who is, at that time, within the Territory, an employee of
      Pentacon or any subsidiary thereof for the purpose or with the intent of
      enticing such employee away from or out of the employ of Pentacon or any
      subsidiary thereof;

            (iii) call upon any person or entity which is, at that time, or
      which has been, within one (1) year prior to the Consummation Date, a
      customer of Pentacon or any subsidiary thereof, of the Company or of any
      of the Other Founding Companies within the Territory for the purpose of
      soliciting or selling products or services that are in direct competition
      with Pentacon within the Territory;

            (iv) call upon any prospective acquisition candidate, on any
      Stockholder's own behalf or on behalf of any competitor in the fastener
      business, which candidate, to the actual knowledge of such Stockholder
      after due inquiry, was called upon by Pentacon or any subsidiary thereof
      or for which, to the actual knowledge of such Stockholder after due

                                      -47-
<PAGE>
      inquiry, Pentacon or any subsidiary thereof made an acquisition analysis, 
      for the purpose of acquiring such entity; or

            (v) disclose customers, whether in existence or proposed, of the
      Company to any person, firm, partnership, corporation or business for any
      reason or purpose relating to the fastener business except to the extent
      that the Company has in the past disclosed such information to the public
      for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any Stockholder from acquiring as a passive investment not more than
one percent (1%) of the capital stock of a competing business whose stock is
traded on a national securities exchange or over-the counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
Pentacon as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to Pentacon for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by Pentacon in the event of breach by such Stockholder,
by injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
Stockholders in light of the activities and business of Pentacon and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of Pentacon; but it is also the intent of Pentacon and the
Stockholders that such covenants be construed and enforced in accordance with
the changing activities; business and locations of Pentacon and its subsidiaries
throughout the term of this covenant. During the term of this covenant, if
Pentacon or one of its subsidiaries engages in new and different activities,
enters a new business or establishes new locations for its current activities or
business in addition to or other than the activities or business it is currently
conducting in the locations currently established therefor, then the
Stockholders will be precluded from soliciting the customers or employees of
such new activities or business or from such new location and from directly
competing with such new activities or business within 100 miles of its
then-established operating location(s) through the term of this covenant.

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

                                      -48-
<PAGE>
      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any Stockholder
against Pentacon or any subsidiary thereof, whether predicated on this Agreement
or otherwise (except for a claim or cause of action based upon Pentacon's
failure to pay or otherwise tender any of the consideration due to the
Stockholders hereunder), shall not constitute a defense to the enforcement by
Pentacon of such covenants. It is specifically agreed that the period of five
(5) years stated at the beginning of this Section 13, during which the
agreements and covenants of each Stockholder made in this Section 13 shall be
effective, shall be computed by excluding from such computation any time during
which such Stockholder is in violation of any provision of this Section 13. The
covenants contained in Section 13 shall not be affected by any breach of any
other provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The Company and the Stockholders hereby agree that this
covenant is a material and substantial part of this transaction.

14.   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1 STOCKHOLDERS. The Stockholders recognize and acknowledge that they
had in the past, currently have, and in the future may possibly have, access to
certain confidential information of the Company, the Other Founding Companies,
and/or Pentacon, such as operational policies, and pricing and cost policies
that are valuable, special and unique assets of the Company's, the Other
Founding Companies' and/or Pentacon's respective businesses. The Stockholders
agree that they will not disclose such confidential information to any person,
firm, corporation, association or other entity for any purpose or reason
whatsoever, except (a) to authorized representatives of Pentacon, (b) following
the Closing, such information may be disclosed by the Stockholders as is
required in the course of performing their duties for Pentacon or the Surviving
Corporation and (c) to counsel and other advisers, provided that such advisers
(other than counsel) agree to the confidentiality provisions of this Section
14.1, unless (i) such information becomes known to the public generally through
no fault of the Stockholders, (ii) disclosure is required by law or the order of
any governmental authority under color of law, provided, that prior to
disclosing any information pursuant to this clause (ii), the Stockholders shall,
if possible, give prior written notice thereof to Pentacon and provide Pentacon
with the opportunity to contest such disclosure, or (iii) the disclosing party
reasonably believes that such disclosure is required in connection with the
defense of a lawsuit against the disclosing party. In the event of a breach or
threatened breach by any of the Stockholders of the provisions of this Section,
Pentacon shall be entitled to an injunction restraining such Stockholders from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting Pentacon from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.
In the event the transactions contemplated by this Agreement are not
consummated, Stockholders shall have none of the above-mentioned restrictions on
their ability to disseminate confidential information with respect to the
Company.

                                      -49-
<PAGE>
      14.2 PENTACON AND NEWCO. Pentacon and Newco recognize and acknowledge that
they had in the past and currently have access to certain confidential
information of the Company, including, but not limited to, customer and prospect
lists, financial information, operational policies, and pricing and cost
policies that are valuable, special and unique assets of the Company's business.
Pentacon and Newco agree that, prior to the Consummation Date, or if the
transactions contemplated by this Agreement are not consummated, they will not,
appropriate or make use of any such information, whether for its own benefit or
the benefit of any other person or entity, for any purpose whatsoever (except
pending the Consummation Date, effecting the transactions contemplated hereby)
disclose such confidential information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, except (a) to
authorized representatives of the Company, (b) to counsel and other advisers,
provided that such advisers (other than counsel) agree to the confidentiality
provisions of this Section 14.2, (c) to the Other Founding Companies and their
representatives pursuant to Section 7.1(a), unless (i) such information becomes
known to the public generally through no fault of Pentacon or Newco, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), Pentacon and Newco shall, if possible, give prior written
notice thereof to the Company and the Stockholders and provide the Company and
the Stockholders with the opportunity to contest such disclosure, or (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, and (d)
to the public to the extent necessary or advisable in connection with the filing
of the Registration Statement and the IPO and the securities laws applicable
thereto and to the operation of Pentacon as a publicly held entity after the
IPO. In the event of a breach or threatened breach by Pentacon or Newco of the
provisions of this Section, the Company and the Stockholders shall be entitled
to an injunction restraining Pentacon and Newco from disclosing, in whole or in
part, such confidential information. Nothing herein shall be construed as
prohibiting the Company and the Stockholders from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach or threatened breach by any of them of the foregoing
covenants, the covenant may be enforced against the other parties by injunctions
and restraining orders or other appropriate equitable relief, without posting
any bond or other security or having to prove irreparable harm or injury.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Consummation Date, or without limitation if the transactions contemplated hereby
are not consummated.

                                      -50-

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Unless otherwise agreed by Pentacon, except
for transfers to immediate family members who agree to be bound by the
restrictions set forth in this Section 15.1 (or trusts or partnerships for the
benefit of charities, the Stockholders, family members, the trustees or partners
of which so agree), for a period of one year from the Closing, except pursuant
to Section 17 hereof, none of the Stockholders shall sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint, or otherwise dispose of any
shares of Pentacon Stock received by the Stockholders in the Merger. The
certificates evidencing the Pentacon Stock delivered to the Stockholders
pursuant to Section 3 of this Agreement will bear a legend substantially in the
form set forth below and containing such other information as Pentacon may deem
necessary or appropriate:

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED
OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT
OR OTHER DISPOSITION PRIOR TO FIRST ANNIVERSARY OF CLOSING DATE. UPON THE
WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE
THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT)
AFTER THE DATE SPECIFIED ABOVE.

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The Stockholders acknowledge that the shares of
Pentacon Stock to be delivered to the Stockholders pursuant to this Agreement
have not been and will not be registered under the 1933 Act (except as provided
in Section 17 hereof) and therefore may not be resold without compliance with
the 1933 Act. The Pentacon Stock to be acquired by such Stockholders pursuant to
this Agreement is being acquired solely for their own respective accounts, for
investment purposes only, and with no present intention of distributing, selling
or otherwise disposing of it in connection with a distribution. The Stockholders
covenant, warrant and represent that none of the shares of Pentacon Stock issued
to such Stockholders will be offered, sold, assigned, pledged, hypothecated,
transferred or otherwise disposed of except after full compliance with all of
the applicable provisions of the 1933 Act and the rules and regulations of the
SEC. All the Pentacon Stock shall bear the following legend in addition to the
legend required under Section 15 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

                                      -51-
<PAGE>
      16.2 ECONOMIC RISK; SOPHISTICATION. The Stockholders are able to bear the
economic risk of an investment in the Pentacon Stock to be acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment in the
Pentacon Stock. The Stockholders party hereto have had an adequate opportunity
to ask questions and receive answers from the officers of Pentacon concerning
any and all matters relating to the transactions described herein including,
without limitation, the background and experience of the current and proposed
officers and directors of Pentacon, the plans for the operations of the business
of Pentacon, the business, operations and financial condition of the Founding
Companies other than the Company, and any plans for additional acquisitions and
the like. The Stockholders have asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever Pentacon proposes to register any Pentacon Stock for its own or others
account under the 1933 Act for a public offering, other than (i) any shelf or
other registration of shares to be used as consideration for acquisitions of
additional businesses by Pentacon and (ii) registrations relating to employee
benefit plans, Pentacon shall give each of the Stockholders prompt written
notice of its intent to do so. Upon the written request of any of the
Stockholders given within 30 days after receipt of such notice, Pentacon shall
cause to be included in such registration all of the Pentacon Stock issued to
the Stockholders pursuant to this Agreement (including any stock issued as (or
issuable upon the conversion or exchange of any convertible security, warrant,
right or other security which is issued by Pentacon as) a dividend or other
distribution with respect to, or in exchange for, or in replacement of such
Pentacon Stock) which any such Stockholder requests, provided that Pentacon
shall have the right to reduce the number of shares included in such
registration to the extent that inclusion of such shares would, in the written
opinion of tax counsel to Pentacon or its independent auditors, reasonably be
likely to jeopardize the status of the transactions contemplated hereby and by
the Registration Statement as a tax-free organization under Section 351 of the
Code. In addition, if Pentacon is advised in writing in good faith by any
managing underwriter of an underwritten offering of the securities being offered
pursuant to any registration statement under this Section 17.1 that the number
of shares to be sold by persons other than Pentacon is greater than the number
of such shares which can be offered without adversely affecting the offering,
Pentacon may reduce pro rata the number of shares offered for the accounts of
such persons (based upon the number of shares held by such person) to a number
deemed satisfactory by such managing underwriter, provided, that, for each such
offering made by Pentacon after the IPO, such reduction shall be made first by
reducing the number of shares to be sold by persons other than Pentacon, the
Stockholders and the Stockholders of the Other Founding Companies (collectively,
the Stockholders and the Stockholders of the other Founding Companies being
referred to herein as the "Founding Stockholders"), and thereafter, if a further
reduction is required, by reducing the number of shares to be sold by the
Founding Stockholders.

                                      -52-

      17.2 REGISTRATION PROCEDURES. Whenever Pentacon is required to register
shares of Pentacon Stock pursuant to Section 17.1, Pentacon will, as
expeditiously as possible:

            (i) Prepare and file with the SEC a registration statement with
      respect to such shares and use its best efforts to cause such registration
      statement to become effective (provided that before filing a registration
      statement or prospectus or any amendments or supplements or term sheets
      thereto, Pentacon will furnish a representative of the Stockholders with
      copies of all such documents proposed to be filed) as promptly as
      practical;

            (ii) Prepare and file with the SEC such amendments and supplements
      to such registration statement and the prospectus used in connection
      therewith as may be necessary to keep such registration statement
      effective for a period of not less than 120 days;

            (iii) Furnish to each Stockholder who so requests such number of
      copies of such registration statement, each amendment and supplement
      thereto and the prospectus included in such registration statement
      (including each preliminary prospectus and any term sheet associated
      therewith), and such other documents as such Stockholder may reasonably
      request in order to facilitate the disposition of the relevant shares;

            (iv) Use its best efforts to register or qualify the securities
      covered by such registration statement under such other securities or Blue
      Sky laws of such jurisdictions as shall be reasonably requested by the
      Stockholders, and to keep such registration or qualification effective
      during the period such registration statement is to be kept effective,
      provided that Pentacon shall not be required to become subject to
      taxation, to qualify to do business or to file a general consent to
      service of process in any such states or jurisdictions;

            (v) Cause all such shares of Pentacon Stock to be listed or included
      on any securities exchanges or trading systems on which similar securities
      issued by Pentacon are then listed or included;

            (vi) Notify each Stockholder at any time when a prospectus relating
      thereto is required to be delivered under the 1933 Act within the period
      that Pentacon is required to keep the registration statement effective of
      the happening of any event as a result of which the prospectus included in
      such registration statement, together with any associated term sheet,
      contains an untrue statement of a material fact or omits any fact
      necessary to make the statement therein not misleading, and, at the
      request of such Stockholder, Pentacon will prepare a supplement or
      amendment to such prospectus so that, as thereafter delivered to the
      purchasers of the covered shares, such prospectus will not contain an
      untrue statement of material fact or omit to state any fact necessary to
      make the statements therein not misleading.

                                      -53-
<PAGE>
      All expenses incurred in connection with the registration under this
Article 17 (including all registration, filing, qualification, legal, printer
and accounting fees, but excluding underwriting commissions and discounts),
shall be borne by Pentacon.

      17.3  INDEMNIFICATION.

            (a) In connection with any registration hereunder, Pentacon shall
indemnify, to the extent permitted by law, each Stockholder against all losses,
claims, damages, liabilities and expenses arising out of or resulting from any
untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or associated term
sheet or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading except insofar as the same are caused by or contained in or omitted
from any information furnished in writing to Pentacon by such indemnified party
expressly for use therein or by any indemnified parties' failure to deliver a
copy of the registration statement or prospectus or any amendment or supplements
thereto after Pentacon has furnished such Indemnified Party with a sufficient
number of copies of the same.

            (b) In connection with any registration hereunder, each Stockholder
shall furnish to Pentacon in writing such information as is reasonably requested
by Pentacon for use in any such registration statement or prospectus and will
indemnify, to the extent permitted by law, Pentacon, its directors and officers
and each person who controls Pentacon (within the meaning of the 1933 Act)
against any losses, claims, damages, liabilities and expenses resulting from any
untrue or alleged untrue statement or material fact or any omission or alleged
omission of a material fact required to be stated in the registration statement
or prospectus or any amendment thereof or supplement thereto necessary to make
the statements therein not misleading, but only to the extent that such untrue
statement or omission is contained in information so furnished in writing by
such Stockholder specifically for use in preparing the registration statement.
Notwithstanding the foregoing, the liability of a Stockholder under this Section
17.3 shall be limited to an amount equal to the net proceeds actually received
by such Stockholder from the sale of the relevant shares covered by the
registration statement.

            (c) Any person entitled to indemnification under this Section will
(i) give prompt notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified parties'
reasonable judgment, a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. Any failure to give prompt notice shall
deprive a party of its right to indemnification hereunder only to the extent
that such failure shall have adversely affected the indemnifying party. If the
defense of any claim is assumed, the indemnifying party will not be subject to
any liability for any settlement made without its consent (but such consent
shall not be unreasonably withheld). An indemnifying party who is not entitled
or elects not to assume the defense of a claim, will not be obligated to pay the
fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the

                                      -54-
<PAGE>
reasonable judgment of any indemnified party, a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Section 17.1 covering an underwritten registered offering, Pentacon and each
participating holder agree to enter into a written agreement with the managing
underwriters in such form and containing such provisions as are customary in the
securities business for such an arrangement between such managing underwriters
and companies of Pentacon's size and investment stature, including
indemnification.

      17.5 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of Pentacon
stock to the public without registration, Pentacon agrees to use its
commercially reasonable efforts to:

            (i) make and keep public information regarding Pentacon available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of Pentacon under the 1933 Act and the 1934 Act at any
      time after it has become subject to such reporting requirements; and

            (iii) so long as a Stockholder owns any restricted Pentacon Common
      Stock, furnish to each Stockholder forthwith upon written request a
      written statement by Pentacon as to its compliance with the reporting
      requirements of Rule 144 (at any time from and after 90 days following the
      effective date of the Registration Statement, and of the 1933 Act and the
      1934 Act (any time after it has become subject to such reporting
      requirements), a copy of the most recent annual or quarterly report of
      Pentacon, and such other reports and documents so filed as a Stockholder
      may reasonably request in availing itself of any rule or regulation of the
      SEC allowing a Stockholder to sell any such shares without registration.

18.   GENERAL

      18.1 COOPERATION. The Company, Stockholders, Pentacon and Newco shall each
deliver or cause to be delivered to the other on the Consummation Date, and at
such other times and places as shall be reasonably agreed to, such additional
instruments as the other may reasonably request for the purpose of carrying out
this Agreement. The Company will cooperate and use its reasonable efforts to
have the present officers, directors and employees of the Company cooperate with
Pentacon on and after the Consummation Date in furnishing information, evidence,
testimony and other assistance in connection with any tax return filing
obligations, actions, proceedings, arrangements or disputes of any nature with
respect to matters pertaining to all periods prior to the Consummation Date.

      18.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the parties
hereunder may not be assigned (except by operation of law) and shall be binding
upon and shall inure to the benefit of the parties hereto, the successors of
Pentacon, and the heirs and legal representatives of the Stockholders.

      18.3 ENTIRE AGREEMENT. This Agreement (including the schedules, exhibits
and annexes attached hereto) and the documents delivered pursuant hereto
constitute the entire agreement and understanding among the Stockholders, the
Company, Newco and Pentacon and supersede any prior agreement and understanding

execution, constitutes a valid and binding agreement of the parties hereto
enforceable in accordance with its terms and may be modified or amended only (i)
pursuant to Section 7.8 with respect to the amendment of Schedules or (ii) by a
written instrument executed by the Stockholders, the Company, Newco and
Pentacon, acting through their respective officers or trustees, duly authorized
by their respective Boards of Directors. Any disclosure made on any Schedule
delivered pursuant hereto shall be deemed to have been disclosed for purposes of
any other Schedule required hereby, provided that the Company shall make a good
faith effort to cross reference disclosure, as necessary or advisable, between
related Schedules, and provided further that the failure to do so will not
affect the validity of such disclosure.

      18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

      18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each party
represents and warrants that it employed no broker or agent in connection with
this transaction and agrees to indemnify the other parties hereto against all
loss, cost, damages or expense arising out of claims for fees or commission of
brokers employed or alleged to have been employed by such indemnifying party.

      18.6 EXPENSES. Whether or not the transactions herein contemplated shall

in connection with this transaction and shall pay all sales, use, transfer, real
property transfer, recording, gains, stock transfer and other similar taxes and
fees ("Transfer Taxes") imposed in connection with the Merger, other than
Transfer Taxes, if any, imposed by the State of Delaware. Each Stockholder shall
file all necessary documentation and Returns with respect to such Transfer
Taxes. In addition, each Stockholder acknowledges that he, and not the Company
or Pentacon, will

                                      -56-

pay all taxes due upon receipt of the consideration payable pursuant to Section

      7.7 NOTIFICATION OF CERTAIN MATTERS BY THE STOCKHOLDERS AND THE COMPANY.
The Stockholders and the Company shall give prompt notice to Pentacon of (i) the
occurrence or non-occurrence of any event the occurrence or nonoccurrence of
which would be likely to cause any representation or warranty of the Company or
the Stockholders contained herein to be untrue or inaccurate in any material
respect at or prior to the Closing and (ii) any material failure of any
Stockholder or the Company to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by such person hereunder. Pentacon
and Newco shall give prompt notice to the Company of (i) the occurrence or
non-occurrence of any event the occurrence or non-occurrence of which would be
likely to cause any representation or warranty of Pentacon or Newco contained
herein to be untrue or inaccurate in any material respect at or prior to the
Closing and (ii) any material failure of Pentacon or Newco to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder. The delivery or deemed delivery of any notice pursuant to this

hereunder of the party delivering such notice, which modification may only be
made pursuant to Section 7.8, (ii) modify the conditions set forth in Sections 8
and 9, or (iii) limit or otherwise affect the remedies available hereunder to

      If, prior to the Closing Date, the Chief Executive Officer, the Chief

Pentacon, Newco, the Surviving Corporation or the Company has a claim hereunder
for indemnification against any STOCKHOLDER(S)

                                     -33-
<PAGE>
(whether or not such claim might exceed the Indemnification Threshold), then
Pentacon shall promptly advise the affected Stockholder(s), in writing, of such
potential claim and provide information supporting the basis and potential
amount of such claim (a "Potential Claim Notice"). This procedure with respect
to Potential Claim Notices is intended to afford the affected Stockholder(s)
notice so that it may attempt to cure or otherwise address the claim prior to
Closing; provided, however, that (i) this procedure shall not affect or delay
Closing and (ii) neither the failure or delay by Pentacon to give a Potential
Claim Notice nor the information included or omitted from a Potential Claim
Notice shall constitute a waiver of, or shall otherwise adversely affect the
right to receive indemnification for, any such claim paid by Pentacon, Newco,
the Surviving Corporation or the Company hereunder after the Closing Date.

      7.8 AMENDMENT OF SCHEDULES. Each party hereto agrees that, with respect to
the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation until 24 hours prior to the
anticipated effectiveness of the Registration Statement to supplement or amend
promptly the Schedules hereto with respect to any matter hereafter arising or
discovered which, if existing or known at the date of this Agreement, would have
been required to be set forth or described in the Schedules, provided however,
that supplements and amendments to Schedules 5.10, 5.11, 5.14 and 5.15 shall
only have to be delivered at the Closing Date, unless such Schedule is to be
amended to reflect an event occurring other than in the ordinary course of
business. Notwithstanding the foregoing sentence, no amendment or supplement to
a Schedule prepared by the Company that constitutes or reflects an event or
occurrence that would have a Material Adverse Effect with respect to the Company
may be made unless Pentacon and a majority of the Founding Companies other than
the Company consent to such amendment or supplement; and provided further, that
no amendment or supplement to a Schedule prepared by Pentacon or Newco that
constitutes or reflects an event or occurrence that would have a Material
Adverse Effect with respect to Pentacon or Newco may be made unless a majority
of the Founding Companies consent to such amendment or supplement. For all
purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 8.1 and 9.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 7.8. In the event that one of the Other
Founding Companies seeks to amend or supplement a Schedule pursuant to Section
7.8 of one of the Other Agreements, and such amendment or supplement constitutes
or reflects an event or occurrence that would have a Material Adverse Effect on
such Other Founding Company, Pentacon shall give the Company written notice
promptly after it has knowledge thereof. If Pentacon and a majority of the
Founding Companies consent to such amendment or supplement, which consent shall
have been deemed given by Pentacon or any Founding Company if no response is
received within 24 hours following receipt of written notice of such amendment
or supplement (or sooner if reasonable and if required by the circumstances
under which such consent is requested), but the Company does not give its
consent, the Company may terminate this Agreement pursuant to Section 12.1(iv)
hereof. In the event that the Company seeks to amend or supplement a Schedule
pursuant to this Section 7.8, and Pentacon and a majority of the Other Founding
Companies do not consent to such amendment or supplement, this Agreement shall
be deemed terminated by mutual consent as set forth in Section 12.1(i) hereof.
In the event that Pentacon or Newco seeks to amend or supplement a

                                     -34-
<PAGE>
Schedule pursuant to this Section 7.8 and a majority of the Founding Companies
do not consent to such amendment or supplement, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 12.1(i) hereof. No party to
this Agreement shall be liable to any other party if this Agreement shall be
terminated pursuant to the provisions of this Section 7.8. No amendment of or
supplement to a Schedule shall be made later than 24 hours prior to the
anticipated effectiveness of the Registration Statement.

      7.9 COOPERATION IN PREPARATION OF REGISTRATION STATEMENT. The Company and
Stockholders shall furnish or cause to be furnished to Pentacon and the

Underwriters in the preparation of, the Registration Statement and the
prospectus included therein (including audited and unaudited financial
statements, prepared in accordance with generally accepted accounting
principles, in form suitable for inclusion in the Registration Statement, except
that the cost of the preparation of any such audited and unaudited Financial
Statements shall be borne by Pentacon). The Company and the Stockholders agree
promptly to advise Pentacon if at any time during the period in which a
prospectus relating to the IPO is required to be delivered under the Securities
Act, any information contained in the prospectus concerning the Company or the
Stockholders becomes incorrect or incomplete in any material respect, and to
provide the information needed to correct such inaccuracy. Insofar as the
information relates solely to the Company or the Stockholders, the Company
represents and warrants as to such information with respect to itself, and each
Stockholder represents and warrants, as to such information with respect to the
Company and himself or herself, severally, but not jointly, that the information
expressly provided for inclusion in the Registration Statement or otherwise
confirmed in writing by such Stockholder will 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, in light of the circumstances under
which they were made, not misleading.

      7.10 FINAL FINANCIAL STATEMENTS. The Company shall provide prior to the
Consummation Date, and Pentacon shall have had sufficient time to review the
unaudited consolidated balance sheets of the Company as of the end of all fiscal
quarters following the Balance Sheet Date, and the unaudited consolidated

fiscal quarters ended after the Balance Sheet Date. Such financial statements
shall have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods indicated
(except as noted therein). Except as noted in such financial statements, all of
such financial statements will present fairly the results of operations of the
Company for the periods indicated therein.

      7.11 FURTHER ASSURANCES. The parties hereto agree to execute and deliver,
or cause to be executed and delivered, such further instruments or documents or
take such other action as may be reasonably necessary or convenient to carry out

automated trading system for which application is made to register the Pentacon
Stock and any changes necessary or advisable in order to permit the delivery of
the opinion contemplated by Section 8.12 hereof.

recognize that one or more filings under the Hart-Scott-Rodino Act may be

determined by the parties to this Agreement that filings under the
Hart-Scott-Rodino Act are required, then: (i) each of the parties hereto agrees
to cooperate and use its best efforts to comply with the Hart-Scott-Rodino Act,
(ii) such compliance by the Stockholders and the Company shall be deemed a
condition precedent in addition to the conditions precedent set forth in Section
8 of this Agreement, and such compliance by Pentacon and Newco shall be deemed a
condition precedent in addition to the conditions precedent set forth in Section
9 of this Agreement, and (iii) the parties agree to cooperate and use their best
efforts to cause all filings required under the Hart-Scott-Rodino Act to be
made. If filings under the Hart-Scott-Rodino Act are required, the costs and
expenses thereof (including filing fees) shall be borne by Pentacon. The
obligation of each party to consummate the transactions contemplated by this
Agreement is subject to the expiration or termination of the waiting period
under the Hart-Scott-Rodino Act, if applicable.

      7.14 PRE-CLOSING NOTIFICATIONS. If, prior to the 25th day after the date
of the final prospectus of Pentacon utilized in connection with the IPO, the
Company or the Stockholders become aware of any fact or circumstance which would
materially affect the accuracy of a representation or warranty of Company or
Stockholders in this Agreement, the Company and the Stockholders shall promptly
give notice of such fact or circumstance to Pentacon. However, subject to the
provisions of Section 7.8, such notification shall not relieve either the
Company or the Stockholders of their respective obligations under this
Agreement, and, subject to the provisions of Section 7.8, at the sole option of
Pentacon, the truth and accuracy of any and all warranties and representations
of the Company, or on behalf of the Company and of Stockholders at the date of
this Agreement and on the Closing Date and on the Consummation Date, shall be a
precondition to the consummation of this transaction.

      7.15 PAYMENT OF INDEBTEDNESS. On the Consummation Date, immediately
following the Effective Time of the Merger, Pentacon will pay, or cause to be
paid, all of the outstanding liabilities, obligations and indebtedness of

such repayment of such liabilities, obligations and indebtedness, Pentacon will
cause all associated guaranties or suretyships of the Stockholders and the Other
Stockholders to be terminated and cancelled. Furthermore, on the Consummation
Date the Company will cause to be paid to the Other Stockholders, the $5,000,000
aggregate redemption payment amount owed by the Company in connection with the

11.   INDEMNIFICATION

      The Stockholders, Pentacon and Newco each make the following covenants
that are applicable to them, respectively:

      11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS. The Stockholders
covenant and agree that they, jointly and severally, will indemnify, defend,
protect and hold harmless Pentacon, Newco, the Company and the Surviving
Corporation at all times, from and after the date of this Agreement until the
Expiration Date (provided that for purposes of Section 11.1(iii) below, the
Expiration Date shall be the date on which the applicable statute of limitations
expires), from and against all claims, damages, actions, suits, proceedings,
demands, assessments, adjustments, costs and expenses (including specifically,
but without limitation, reasonable attorneys' fees and expenses of
investigation) incurred by Pentacon, Newco, the Company or the Surviving
Corporation as a result of or arising from (i) any breach of the representations
and warranties of the Stockholders or the Company set forth herein or on the
definitive, final schedules or certificates delivered by them in connection
herewith (but excluding any representations or warranties made by the Other
Stockholders with respect to their Common Stock), (ii) any breach of any
agreement on the part of the Stockholders or, prior to Closing, the Company
under this Agreement, or (iii) any liability under the 1933 Act, the 1934 Act or
other Federal or state law or regulation, at common law or otherwise, arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact relating to the Company or the Stockholders, and provided in
writing to Pentacon or its counsel by the Company or the Stockholders for
inclusion in the Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, or arising out of or
based upon any omission or alleged omission to state therein a material fact
relating to the Company or the Stockholders required to be stated therein or
necessary to make the statements therein not misleading, provided, however, that
such indemnity shall not inure to the benefit of Pentacon, Newco, the Company or
the Surviving Corporation to the extent that such untrue statement (or alleged
untrue statement) was made in, or omission (or alleged omission) occurred in,
any preliminary prospectus and the Stockholders provided, in writing, corrected
information to Pentacon counsel and to Pentacon for inclusion in the final
prospectus, and such information was not so included or properly delivered, and
provided further, that no Stockholder shall be liable for any

                                     -43-
<PAGE>
indemnification obligation pursuant to this Section 11.1(iii) to the extent
attributable to a breach of any representation, warranty or agreement made
herein individually by any Other Stockholder.

      Pentacon and Newco acknowledge and agree that other than the
representations and warranties of Company or Stockholders specifically contained
in this Agreement, there are no representations or warranties of Company or
Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

      Pentacon, Newco and the Company further acknowledge and agree that, should
the Closing occur, their sole and exclusive remedy with respect to any and all
claims relating to this Agreement and the transactions contemplated in this
Agreement, shall be pursuant to the indemnification provisions set forth in this
Section 11.1. Pentacon, Newco and the Company hereby waive, from and after the
Closing, to the fullest extent permitted under applicable law, any and all
rights, claims and causes of action they or any indemnified person may have
against the Company or any Stockholder relating to this Agreement or the
transactions contemplated hereby arising under or based upon any federal, state,
local or foreign statute, law, rule, regulation or otherwise (and other than
pursuant to the terms of this Agreement).

      11.2 INDEMNIFICATION BY PENTACON. Pentacon covenants and agrees that it
will indemnify, defend, protect and hold harmless the Stockholders at all times
from and after the date of this Agreement until the Expiration Date, from and
against all claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses (including specifically, but without limitation,
reasonable attorneys' fees and expenses of investigation) incurred by the
Stockholders as a result of or arising from (i) any breach by Pentacon or Newco
of their representations and warranties set forth herein or on the definitive,
final schedules or certificates attached delivered by them pursuant hereto, (ii)
any breach of any agreement on the part of Pentacon or Newco under this
Agreement or any other agreement delivered pursuant hereto, (iii) any
liabilities which the Stockholders may incur due to Pentacon's or Newco's or the
Surviving Corporation's failure to pay, perform or discharge when due any of the
liabilities and obligations of the Company for which Pentacon, Newco or the
Surviving Corporation is responsible pursuant to this Agreement (except to the
extent that Pentacon or Newco has bona fide claims hereunder against the
Stockholders by reason of such liabilities); or (iv) any liability under the
1933 Act, the 1934 Act or other Federal or state law or regulation, at common
law or otherwise, arising out of or based upon any untrue statement or alleged
untrue statement of a material fact relating to Pentacon, Newco or any of the
Other Founding Companies contained in any preliminary prospectus, the
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, or arising out of or based upon any
omission or alleged omission to state therein a material fact relating to
Pentacon or Newco or any of the Other Founding Companies required to be stated
therein or necessary to make the statements therein not misleading.

                                     -44-
<PAGE>
      11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has actual knowledge of any claim
by a Person (including a governmental agency) not a party to this Agreement
("Third Person"), or the commencement of any action or proceeding by a Third
Person, with respect to which the Indemnified Person would be entitled to
receive indemnification pursuant to Section 11, the Indemnified Party shall, as
a condition precedent to a claim with respect thereto being made against any
party obligated to provide indemnification pursuant to Section 11.1 or 11.2
hereof (hereinafter the "Indemnifying Party"), give the Indemnifying Party
written notice of such claim or the commencement of such action or proceeding.
Such notice shall state the nature and the basis of such claim and a reasonable
estimate of the amount thereof. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same in good faith and diligently,
provided that the Indemnifying Party shall not settle any criminal proceeding
without the written consent of the Indemnified Party. If the Indemnifying Party
undertakes to defend or settle, it shall promptly notify the Indemnified Party
of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in the defense thereof and in any settlement
thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records or information reasonably
requested by the Indemnifying Party that are in the Indemnified Party's
possession or control. All Indemnified Parties shall use the same counsel, which
shall be the counsel selected by Indemnifying Party, provided that if counsel to
the Indemnifying Party shall have a conflict of interest that prevents counsel
for the Indemnifying Party from representing Indemnified Party, Indemnified
Party shall have the right to participate in such matter through counsel of its
own choosing and Indemnifying Party will reimburse the Indemnified Party for the
reasonable expenses of its counsel. After the Indemnifying Party has notified
the Indemnified Party of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnifying Party diligently pursues
such defense through appropriate proceedings, the Indemnifying Party shall not
be liable for any additional legal expenses incurred by the Indemnified Party in
connection with any defense or settlement of such asserted liability, except (i)
as set forth in the preceding sentence and (ii) to the extent such participation
is requested by the Indemnifying Party, in which event the Indemnified Party
shall be reimbursed by the Indemnifying Party for reasonable additional legal
expenses and out-of-pocket expenses. If the Indemnifying Party desires to accept
a final and complete settlement of any such Third Person claim and the
Indemnified Party refuses to consent to such settlement, then the Indemnifying
Party's liability under this Section with respect to such Third Person claim
shall be limited to the amount so offered in settlement by said Third Person.
Upon agreement as to such settlement between said Third Person and the
Indemnifying Party, the Indemnifying Party shall, in exchange for a complete
release from the Indemnified Party, promptly pay to the Indemnified Party the
amount agreed to in such settlement and the Indemnified Party shall, from that
moment on, bear full responsibility for any additional costs of defense which it
subsequently incurs with respect to such claim and all additional costs of
settlement or judgment. If the Indemnifying Party does not undertake to defend
such matter to which the Indemnified Party is entitled to indemnification
hereunder, or fails diligently to pursue such defense, the Indemnified Party may
undertake such defense through counsel of its choice, at the cost and expense of
the Indemnifying Party, and the Indemnified Party may settle such matter, and
the Indemnifying Party shall reimburse the

                                     -45-
<PAGE>
Indemnified Party for the amount paid in such settlement and any other
liabilities or expenses incurred by the Indemnified Party in connection
therewith, provided, however, that under no circumstances shall the Indemnified
Party settle any Third Person claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld or delayed.
All settlements hereunder shall effect a complete release of the Indemnified
Party, unless the Indemnified Party otherwise agrees in writing. The parties
hereto will make appropriate adjustments for insurance proceeds in determining
the amount of any indemnification obligation under this Section.

      11.4 EXCLUSIVE REMEDY. (a) The indemnification provided for in this
Section 11 shall (except as prohibited by ERISA) be the exclusive remedy in any
action seeking damages or any other form of monetary relief brought by any party
to this Agreement against another party, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case pursuant to Section
14.3 or otherwise, to seek injunctive or other equitable relief (except for
rescission which shall not be available) for a breach or threatened breach of
this Agreement. Any indemnity payment under this Section 11 shall be treated as
an adjustment to the exchange consideration for tax purposes unless a final
determination (which shall include the execution of a Form 870-AD or successor
form) with respect to the indemnified party or any of its affiliate causes any
such payment not to be treated as an adjustment to the exchange consideration
for U.S. Federal Income Tax purposes.

            (b) Nothing in this Article 11 shall restrict the Stockholders from
subrogation or seeking reimbursement from third parties other than the Company.

      11.5 LIMITATIONS ON INDEMNIFICATION. Pentacon, Newco, the Surviving
Corporation and the other persons or entities indemnified pursuant to Section
11.1 or 11.2 shall not assert any claim for indemnification hereunder against
the Stockholders after the applicable Expiration Date and in no event until such
time as, and solely to the extent that, the aggregate of all claims which such
persons may have against the Stockholders shall exceed the greater of 1% of the
value of the total consideration (including stock and cash) received by the
Stockholders from the Merger or $100,000 (the "Indemnification Threshold"), and
then only to the extent of the excess over the Indemnification Threshold.
Stockholders shall not assert any claim for indemnification hereunder against
Pentacon or Newco after the applicable Expiration Date and in no event until
such time as, and solely to the extent that, the aggregate of all claims which
Stockholders may have against Pentacon or Newco shall exceed the Indemnification
Threshold, and then only to the extent of the excess over the Indemnification
Threshold.

      The Indemnification Threshold and other limitations contained in this
Section 11.5 shall not be applicable to any breach of covenants made by the
Stockholders in this Agreement which require an action or inaction by such
Stockholders from and after the Closing Date (I.E., Article 10, Article 11,
Article 13, Article 14, Article 17 and Sections 18.1 and 18.6). No person shall
be entitled to indemnification under this Section 11 if, and only to the extent
that such person's claim for indemnification is directly related to a breach by
such person of any representation, warranty, covenant or other agreement set
forth in this Agreement.

                                     -46-
<PAGE>
      The pursuit by Pentacon, the Surviving Corporation, Newco or the Company,
of any claim for indemnification hereunder against a Stockholder shall require a
majority vote of the board of directors of Pentacon excluding for the purposes
of such vote, any director who was previously a stockholder of the Company or is
a representative of the stockholders of the Company as existing prior to the
closing of the transactions contemplated in this Agreement.

      Notwithstanding any other term of this Agreement, no Stockholder shall be
liable (in the aggregate from time to time taking into account all
indemnification payments made hereunder) under this Section 11(a) for any amount
which is less than or equal to the Indemnification Threshold (and then only to
the extent of the excess over the Indemnification Threshold) or (b) for any
amount which exceeds the amount of proceeds (including cash and stock) received
by such Stockholder in connection with the Merger. Each Stockholder shall have
the option of satisfying his or her indemnity obligation in cash and/or by
returning or transferring shares of Pentacon Stock to Pentacon or any other
Indemnified Party. For purposes of calculating the value of the Pentacon Stock
received by a Stockholder and satisfying any indemnity claim by returning or
transferring Pentacon Stock, Pentacon Stock shall be valued at its initial
public offering price as set forth in the Registration Statement.

      Notwithstanding any of the foregoing provisions of this Section 11 that
might be read to the contrary, it is the agreement of the parties that the
Indemnification Threshold be given full effect under all circumstances.
Accordingly, insofar as any of the foregoing provisions of this Section 11 may
hold harmless an Indemnified Party before the Indemnification Threshold has been
met, then Pentacon and the Stockholders shall cooperate in good faith to
establish an equitable procedure pursuant to which Pentacon reimburses or causes
the reimbursement to the affected Stockholder(s) of all expenditures and
payments by Stockholders that are intended to be absorbed and borne by any
Indemnified Parties as a result of the prior application of the Indemnification
Threshold or otherwise takes such action as may be reasonably necessary to give
effect to the Indemnification Threshold.

12.   TERMINATION OF AGREEMENT

      12.1 TERMINATION. This Agreement may be terminated at any time prior to
the Consummation Date solely:

            (i) by mutual consent of the boards of directors of Pentacon and the
      Company;

            (ii) by the Stockholders or the Company (acting through its board of
      directors), on the one hand, or by Pentacon (acting through its board of
      directors), on the other hand, if the transactions contemplated by this
      Agreement to take place at the Closing shall not have been consummated by
      February 28, 1998, unless the failure of such transactions to be
      consummated is due to the willful failure of the party seeking to
      terminate this Agreement to perform any of its obligations under this
      Agreement to the extent required to be performed by it prior to or on the
      Consummation Date;

                                     -47-
<PAGE>
            (iii) by the Stockholders or Company, on the one hand, or by
      Pentacon, on the other hand, if a material breach or default shall be made
      by the other party in the observance or in the due and timely performance
      of any of the covenants or agreements contained herein, and the curing of
      such default shall not have been made on or before the Consummation Date
      or by the Stockholders or the Company, if the conditions set forth in
      Section 8 hereof have not been satisfied or waived as of the Closing Date
      or the Consummation Date, as applicable, or by Pentacon, if the conditions
      set forth in Section 9 hereof have not been satisfied or waived as of the
      Closing Date or the Consummation Date, as applicable;

            (iv)  pursuant to Section 7.8 hereof;

            (v) pursuant to the termination provisions contained in Section 4
      hereof; or

            (vi) pursuant to the other express terms of this Agreement.

      12.2 LIABILITIES IN EVENT OF TERMINATION. Except as provided in Section
7.8 hereof, the termination of this Agreement will in no way limit any
obligation or liability of any party based on or arising from a breach or
default by such party with respect to any of its representations, warranties,
covenants or agreements contained in this Agreement including, but not limited
to, legal and audit costs and out of pocket expenses.

13.   NONCOMPETITION

      13.1 PROHIBITED ACTIVITIES. The Stockholders will not, for a period of
five (5) years following the Consummation Date, for any reason whatsoever,
directly or indirectly, for themselves or on behalf of or in conjunction with
any other person, persons, company, partnership, corporation or business of
whatever nature:

            (i) except as disclosed in Schedule 13.1, engage, as an officer,
      director, shareholder, owner, partner, joint venturer, or in a managerial
      capacity, whether as an employee, independent contractor, consultant or
      advisor, or as a sales representative, in any fastener business or
      operation or related services business in direct competition with Pentacon
      or any of the subsidiaries thereof, within 100 miles of where the Company
      or any of its subsidiaries conducted business prior to the effectiveness
      of the Merger (the "Territory");

            (ii) except with the prior written consent of Pentacon, call upon
      any person who is, at that time, within the Territory, an employee of
      Pentacon or any subsidiary thereof for the purpose or with the intent of
      enticing such employee away from or out of the employ of Pentacon or any
      subsidiary thereof;

            (iii) call upon any person or entity which is, at that time, or
      which has been, within one (1) year prior to the Consummation Date, a
      customer of Pentacon or any subsidiary

                                     -48-
<PAGE>
      thereof, of the Company or of any of the Other Founding Companies within
      the Territory for the purpose of soliciting or selling products or
      services that are in direct competition with Pentacon within the
      Territory;

            (iv) call upon any prospective acquisition candidate, on any
      Stockholder's own behalf or on behalf of any competitor in the fastener
      business, which candidate, to the actual knowledge of such Stockholder
      after due inquiry, was called upon by Pentacon or any subsidiary thereof
      or for which, to the actual knowledge of such Stockholder after due
      inquiry, Pentacon or any subsidiary thereof made an acquisition analysis,
      for the purpose of acquiring such entity; or

            (v) disclose customers, whether in existence or proposed, of the
      Company to any person, firm, partnership, corporation or business for any
      reason or purpose relating to the fastener business except to the extent
      that the Company has in the past disclosed such information to the public
      for valid business reasons.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit any Stockholder from acquiring as a passive investment not more than
one percent (1%) of the capital stock of a competing business whose stock is
traded on a national securities exchange or over-the counter.

      13.2 DAMAGES. Because of the difficulty of measuring economic losses to
Pentacon as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to Pentacon for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by Pentacon in the event of breach by such Stockholder,
by injunctions and restraining orders.

      13.3 REASONABLE RESTRAINT. It is agreed by the parties hereto that the
foregoing covenants in this Section 13 impose a reasonable restraint on the
Stockholders in light of the activities and business of Pentacon and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of Pentacon; but it is also the intent of Pentacon and the
Stockholders that such covenants be construed and enforced in accordance with
the changing activities; business and locations of Pentacon and its subsidiaries
throughout the term of this covenant. During the term of this covenant, if
Pentacon or one of its subsidiaries engages in new and different activities,
enters a new business or establishes new locations for its current activities or
business in addition to or other than the activities or business it is currently
conducting in the locations currently established therefor, then the
Stockholders will be precluded from soliciting the customers or employees of
such new activities or business or from such new location and from directly
competing with such new activities or business within 100 miles of its
then-established operating location(s) through the term of this covenant.

                                     -49-

      13.4 SEVERABILITY; REFORMATION. The covenants in this Section 13 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      13.5 INDEPENDENT COVENANT. All of the covenants in this Section 13 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any Stockholder
against Pentacon or any subsidiary thereof, whether predicated on this Agreement
or otherwise (except for a claim or cause of action based upon Pentacon's
failure to pay or otherwise tender any of the consideration due to the
Stockholders hereunder), shall not constitute a defense to the enforcement by
Pentacon of such covenants. It is specifically agreed that the period of five
(5) years stated at the beginning of this Section 13, during which the
agreements and covenants of each Stockholder made in this Section 13 shall be
effective, shall be computed by excluding from such computation any time during
which such Stockholder is in violation of any provision of this Section 13. The
covenants contained in Section 13 shall not be affected by any breach of any
other provision hereof by any party hereto and shall have no effect if the
transactions contemplated by this Agreement are not consummated.

      13.6 MATERIALITY. The Company and the Stockholders hereby agree that this
covenant is a material and substantial part of this transaction.

14.   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

      14.1 STOCKHOLDERS. The Stockholders and each of the Other Stockholders by
their execution of the Limited Joinder hereto recognize and acknowledge that
they had in the past, currently have, and in the future may possibly have,
access to certain confidential information of the Company, the Other Founding
Companies, and/or Pentacon, such as operational policies, and pricing and cost
policies that are valuable, special and unique assets of the Company's, the
Other Founding Companies' and/or Pentacon's respective businesses. The
Stockholders and Other Stockholders agree that they will not disclose such
confidential information to any person, firm, corporation, association or other
entity for any purpose or reason whatsoever, except (a) to authorized
representatives of Pentacon, (b) following the Closing, such information may be
disclosed by the Stockholders as is required in the course of performing their
duties for Pentacon or the Surviving Corporation and (c) to counsel and other
advisers, provided that such advisers (other than counsel) agree to the
confidentiality provisions of this Section 14.1, unless (i) such information
becomes known to the public generally through no fault of the Stockholders or
Other Stockholders (as the case may be), (ii) disclosure is required by law or
the order of any governmental authority under color of law, provided, that prior
to disclosing any information pursuant to this clause (ii), the Stockholders
shall, if possible, give prior written notice thereof to Pentacon and provide
Pentacon with the opportunity to contest such disclosure, or (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party.

                                     -50-
<PAGE>
In the event of a breach or threatened breach by any of the Stockholders or
Other Stockholders of the provisions of this Section, Pentacon shall be entitled
to an injunction restraining such Stockholders or Other Stockholders from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting Pentacon from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.
In the event the transactions contemplated by this Agreement are not
consummated, the Stockholders or Other Stockholders shall have none of the
above-mentioned restrictions on their ability to disseminate confidential
information with respect to the Company.

      14.2 PENTACON AND NEWCO. Pentacon and Newco recognize and acknowledge that
they had in the past and currently have access to certain confidential
information of the Company, including, but not limited to, customer and prospect
lists, financial information, operational policies, and pricing and cost
policies that are valuable, special and unique assets of the Company's business.
Pentacon and Newco agree that, prior to the Consummation Date, or if the
transactions contemplated by this Agreement are not consummated, they will not,
appropriate or make use of any such information, whether for its own benefit or
the benefit of any other person or entity, for any purpose whatsoever (except
pending the Consummation Date, effecting the transactions contemplated hereby)
disclose such confidential information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, except (a) to
authorized representatives of the Company, (b) to counsel and other advisers,
provided that such advisers (other than counsel) agree to the confidentiality
provisions of this Section 14.2, (c) to the Other Founding Companies and their
representatives pursuant to Section 7.1(a), unless (i) such information becomes
known to the public generally through no fault of Pentacon or Newco, (ii)
disclosure is required by law or the order of any governmental authority under
color of law, provided, that prior to disclosing any information pursuant to
this clause (ii), Pentacon and Newco shall, if possible, give prior written
notice thereof to the Company and the Stockholders and provide the Company and
the Stockholders with the opportunity to contest such disclosure, or (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party, and (d)
to the public to the extent necessary or advisable in connection with the filing
of the Registration Statement and the IPO and the securities laws applicable
thereto and to the operation of Pentacon as a publicly held entity after the
IPO. In the event of a breach or threatened breach by Pentacon or Newco of the
provisions of this Section, the Company and the Stockholders shall be entitled
to an injunction restraining Pentacon and Newco from disclosing, in whole or in
part, such confidential information. Nothing herein shall be construed as
prohibiting the Company and the Stockholders from pursuing any other available
remedy for such breach or threatened breach, including the recovery of damages.

      14.3 DAMAGES. Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 14.1 and 14.2, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, the parties hereto agree that, in the
event of a breach or threatened breach by any of them of the foregoing
covenants, the covenant may be enforced against the other parties by injunctions
and

                                     -51-
<PAGE>
restraining orders or other appropriate equitable relief, without posting any
bond or other security or having to prove irreparable harm or injury.

      14.4 SURVIVAL. The obligations of the parties under this Article 14 shall
survive the termination of this Agreement for a period of five years from the
Consummation Date, or without limitation if the transactions contemplated hereby
are not consummated.

15.   TRANSFER RESTRICTIONS

      15.1 TRANSFER RESTRICTIONS. Unless otherwise agreed by Pentacon, except
for transfers to immediate family members who agree to be bound by the
restrictions set forth in this Section 15.1 (or trusts or partnerships for the
benefit of charities, the Stockholders or Other Stockholders, family members,
the trustees or partners of which so agree), for a period of one year from the
Closing, except pursuant to Section 17 hereof, none of the Stockholders or Other
Stockholders shall sell, assign, exchange, transfer, encumber, pledge,
distribute, appoint, or otherwise dispose of any shares of Pentacon Stock
received by the Stockholders or Other Stockholders in the Merger. The
certificates evidencing the Pentacon Stock delivered to the Stockholders or
Other Stockholders pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below and containing such other information
as Pentacon may deem necessary or appropriate:

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED
OF, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION, APPOINTMENT
OR OTHER DISPOSITION PRIOR TO FIRST ANNIVERSARY OF CLOSING DATE. UPON THE
WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE
THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT)
AFTER THE DATE SPECIFIED ABOVE.

16.   FEDERAL SECURITIES ACT REPRESENTATIONS

      16.1 COMPLIANCE WITH LAW. The Stockholders acknowledge that the shares of
Pentacon Stock to be delivered to the Stockholders pursuant to this Agreement
have not been and will not be registered under the 1933 Act (except as provided
in Section 17 hereof) and therefore may not be resold without compliance with
the 1933 Act. The Pentacon Stock to be acquired by such Stockholders pursuant to
this Agreement is being acquired solely for their own respective accounts, for
investment purposes only, and with no present intention of distributing, selling
or otherwise disposing of it in connection with a distribution. The Stockholders
covenant, warrant and represent that none of the shares of Pentacon Stock issued
to such Stockholders will be offered, sold, assigned, pledged, hypothecated,
transferred or otherwise disposed of except after full compliance with all of
the applicable provisions of the 1933 Act and the rules and regulations of the
SEC. All the Pentacon

                                     -52-
<PAGE>
Stock shall bear the following legend in addition to the legend required under
Section 15 of this Agreement:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF THE HOLDER
HEREOF COMPLIES WITH THE ACT AND APPLICABLE SECURITIES LAW.

      16.2 ECONOMIC RISK; SOPHISTICATION. The Stockholders are able to bear the
economic risk of an investment in the Pentacon Stock to be acquired pursuant to
this Agreement and can afford to sustain a total loss of such investment and
have such knowledge and experience in financial and business matters that they
are capable of evaluating the merits and risks of the proposed investment in the
Pentacon Stock. The Stockholders party hereto have had an adequate opportunity
to ask questions and receive answers from the officers of Pentacon concerning
any and all matters relating to the transactions described herein including,
without limitation, the background and experience of the current and proposed
officers and directors of Pentacon, the plans for the operations of the business
of Pentacon, the business, operations and financial condition of the Founding
Companies other than the Company, and any plans for additional acquisitions and
the like. The Stockholders have asked any and all questions in the nature
described in the preceding sentence and all questions have been answered to
their satisfaction.

17.   REGISTRATION RIGHTS

      17.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the Closing,
whenever Pentacon proposes to register any Pentacon Stock for its own or others
account under the 1933 Act for a public offering, other than (i) any shelf or
other registration of shares to be used as consideration for acquisitions of
additional businesses by Pentacon and (ii) registrations relating to employee
benefit plans, Pentacon shall give each of the Stockholders and Other
Stockholders prompt written notice of its intent to do so. Upon the written
request of any of the Stockholders given within 30 days after receipt of such
notice, Pentacon shall cause to be included in such registration all of the
Pentacon Stock issued to the Stockholders and Other Stockholders pursuant to
this Agreement (including any stock issued as (or issuable upon the conversion
or exchange of any convertible security, warrant, right or other security which
is issued by Pentacon as) a dividend or other distribution with respect to, or
in exchange for, or in replacement of such Pentacon Stock) which any such
Stockholder and Other Stockholder requests, provided that Pentacon shall have
the right to reduce the number of shares included in such registration to the
extent that inclusion of such shares would, in the written opinion of tax
counsel to Pentacon or its independent auditors, reasonably be likely to
jeopardize the status of the transactions contemplated hereby and by the
Registration Statement as a tax-free organization under Section 351 of the Code.
In addition, if Pentacon is advised in writing in good faith by any managing
underwriter of an underwritten offering of the securities being offered pursuant
to any registration statement under this Section 17.1 that the number of shares
to be sold by persons other than Pentacon is greater than the number of such
shares which can be offered without adversely affecting the offering, Pentacon
may reduce pro rata the

                                     -53-
<PAGE>
number of shares offered for the accounts of such persons (based upon the number
of shares held by such person) to a number deemed satisfactory by such managing
underwriter, provided, that, for each such offering made by Pentacon after the
IPO, such reduction shall be made first by reducing the number of shares to be
sold by persons other than Pentacon, the Stockholders and Other Stockholders and
the Stockholders of the Other Founding Companies (collectively, the
Stockholders, the Other Stockholders and the Stockholders of the other Founding
Companies being referred to herein as the "Founding Stockholders"), and
thereafter, if a further reduction is required, by reducing the number of shares
to be sold by the Founding Stockholders.

      17.2 REGISTRATION PROCEDURES. Whenever Pentacon is required to register
shares of Pentacon Stock pursuant to Section 17.1, Pentacon will, as
expeditiously as possible:

            (i) Prepare and file with the SEC a registration statement with
      respect to such shares and use its best efforts to cause such registration
      statement to become effective (provided that before filing a registration
      statement or prospectus or any amendments or supplements or term sheets
      thereto, Pentacon will furnish a representative of the Stockholders and
      Other Stockholders with copies of all such documents proposed to be filed)
      as promptly as practical;

            (ii) Prepare and file with the SEC such amendments and supplements
      to such registration statement and the prospectus used in connection
      therewith as may be necessary to keep such registration statement
      effective for a period of not less than 120 days;

            (iii) Furnish to each Stockholder or Other Stockholder who so
      requests such number of copies of such registration statement, each
      amendment and supplement thereto and the prospectus included in such
      registration statement (including each preliminary prospectus and any term
      sheet associated therewith), and such other documents as such Stockholder
      or Other Stockholder may reasonably request in order to facilitate the
      disposition of the relevant shares;

            (iv) Use its best efforts to register or qualify the securities
      covered by such registration statement under such other securities or Blue
      Sky laws of such jurisdictions as shall be reasonably requested by the
      Stockholders or Other Stockholders, and to keep such registration or
      qualification effective during the period such registration statement is
      to be kept effective, provided that Pentacon shall not be required to
      become subject to taxation, to qualify to do business or to file a general
      consent to service of process in any such states or jurisdictions;

            (v) Cause all such shares of Pentacon Stock to be listed or included
      on any securities exchanges or trading systems on which similar securities
      issued by Pentacon are then listed or included;

                                     -54-
<PAGE>
            (vi) Notify each Stockholder or Other Stockholder at any time when a
      prospectus relating thereto is required to be delivered under the 1933 Act
      within the period that Pentacon is required to keep the registration
      statement effective of the happening of any event as a result of which the
      prospectus included in such registration statement, together with any
      associated term sheet, contains an untrue statement of a material fact or
      omits any fact necessary to make the statement therein not misleading,
      and, at the request of such Stockholder or Other Stockholder, Pentacon
      will prepare a supplement or amendment to such prospectus so that, as
      thereafter delivered to the purchasers of the covered shares, such
      prospectus will not contain an untrue statement of material fact or omit
      to state any fact necessary to make the statements therein not misleading.

      All expenses incurred in connection with the registration under this
Article 17 (including all registration, filing, qualification, legal, printer
and accounting fees, but excluding underwriting commissions and discounts),
shall be borne by Pentacon.

      17.3  INDEMNIFICATION.

            (a) In connection with any registration hereunder, Pentacon shall
indemnify, to the extent permitted by law, each Stockholder and Other
Stockholder against all losses, claims, damages, liabilities and expenses
arising out of or resulting from any untrue or alleged untrue statement of
material fact contained in any registration statement, prospectus or preliminary
prospectus or associated term sheet or any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading except insofar as the same are caused by or
contained in or omitted from any information furnished in writing to Pentacon by
such indemnified party expressly for use therein or by any indemnified parties'
failure to deliver a copy of the registration statement or prospectus or any
amendment or supplements thereto after Pentacon has furnished such Indemnified
Party with a sufficient number of copies of the same.

            (b) In connection with any registration hereunder, each Stockholder
or Other Stockholder shall furnish to Pentacon in writing such information as is
reasonably requested by Pentacon for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, Pentacon, its
directors and officers and each person who controls Pentacon (within the meaning
of the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged untrue statement or material fact or any
omission or alleged omission of a material fact required to be stated in the
registration statement or prospectus or any amendment thereof or supplement
thereto necessary to make the statements therein not misleading, but only to the
extent that such untrue statement or omission is contained in information so
furnished in writing by such Stockholder specifically for use in preparing the
registration statement. Notwithstanding the foregoing, the liability of a
Stockholder or Other Stockholder under this Section 17.3 shall be limited to an
amount equal to the net proceeds actually received by such Stockholder or Other
Stockholder from the sale of the relevant shares covered by the registration
statement.

                                     -55-
<PAGE>
            (c) Any person entitled to indemnification under this Section will
(i) give prompt notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified parties'
reasonable judgment, a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. Any failure to give prompt notice shall
deprive a party of its right to indemnification hereunder only to the extent
that such failure shall have adversely affected the indemnifying party. If the
defense of any claim is assumed, the indemnifying party will not be subject to
any liability for any settlement made without its consent (but such consent
shall not be unreasonably withheld). An indemnifying party who is not entitled
or elects not to assume the defense of a claim, will not be obligated to pay the
fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party, a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

      17.4 UNDERWRITING AGREEMENT. In connection with each registration pursuant
to Section 17.1 covering an underwritten registered offering, Pentacon and each
participating holder agree to enter into a written agreement with the managing
underwriters in such form and containing such provisions as are customary in the
securities business for such an arrangement between such managing underwriters
and companies of Pentacon's size and investment stature, including
indemnification.

      17.5 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the sale of Pentacon
stock to the public without registration, Pentacon agrees to use commercially
reasonable efforts to:

            (i) make and keep public information regarding Pentacon available as
      those terms are understood and defined in Rule 144 under the 1933 Act for
      a period of four years beginning 90 days following the effective date of
      the Registration Statement;

            (ii) file with the SEC in a timely manner all reports and other
      documents required of Pentacon under the 1933 Act and the 1934 Act at any
      time after it has become subject to such reporting requirements; and

            (iii) so long as a Stockholder or Other Stockholder owns any
      restricted Pentacon Stock, furnish to each Stockholder or Other
      Stockholder forthwith upon written request a written statement by Pentacon
      as to its compliance with the reporting requirements of Rule 144 (at any
      time from and after 90 days following the effective date of the
      Registration Statement, and of the 1933 Act and the 1934 Act (any time
      after it has become subject to such reporting requirements), a copy of the
      most recent annual or quarterly report of Pentacon, and such other reports
      and documents so filed as a Stockholder or Other Stockholder may
      reasonably request in availing itself of any rule or regulation of the SEC
      allowing a Stockholder or Other Stockholder to sell any such shares
      without registration.

                                     -56-

18.   GENERAL

      18.1 COOPERATION. The Company, Stockholders or Other Stockholders,
Pentacon and Newco shall each deliver or cause to be delivered to the other on
the Consummation Date, and at such other times and places as shall be reasonably
agreed to, such additional instruments as the other may reasonably request for
the purpose of carrying out this Agreement. The Company will cooperate and use
its reasonable efforts to have the present officers, directors and employees of
the Company cooperate with Pentacon on and after the Consummation Date in
furnishing information, evidence, testimony and other assistance in connection
with any tax return filing obligations, actions, proceedings, arrangements or
disputes of any nature with respect to matters pertaining to all periods prior
to the Consummation Date.

      18.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the parties
hereunder may not be assigned (except by operation of law) and shall be binding

Pentacon, and the heirs and legal representatives of the Stockholders.

      18.3 ENTIRE AGREEMENT. This Agreement (including the schedules, exhibits
and annexes attached hereto) and the documents delivered pursuant hereto

enforceable in accordance with its terms and may be modified or amended only (i)
pursuant to Section 7.8 with respect to the amendment of Schedules or (ii) by a
written instrument executed by the Stockholders, the Company, Newco and
Pentacon, acting through their respective officers or trustees, duly authorized
by their respective Boards of Directors. Any disclosure made on any Schedule
delivered pursuant hereto shall be deemed to have been disclosed for purposes of
any other Schedule required hereby, provided that the Company shall make a good
faith effort to cross reference disclosure, as necessary or advisable, between
related Schedules, and provided further that the failure to do so will not
affect the validity of such disclosure.

      18.4 COUNTERPARTS. This Agreement may be executed simultaneously in two
(2) or more counterparts, each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

      18.5 BROKERS AND AGENTS. Except as disclosed on Schedule 18.5, each party
represents and warrants that it employed no broker or agent in connection with
this transaction and agrees to indemnify the other parties hereto against all
loss, cost, damages or expense arising out of claims for fees or commission of
brokers employed or alleged to have been employed by such indemnifying party.

                CHIEF EXECUTIVE OFFICER'S EMPLOYMENT AGREEMENT

      This Employment Agreement (the "Agreement") by and between Pentacon, Inc.,
a Delaware corporation (the "Company"), and Mark E. Baldwin ("Executive") is
hereby entered into and effective as of the 2nd day of December, 1997. This
Agreement hereby supersedes any other employment agreements or understandings,
written or oral, between the Company and Executive.

                                   RECITALS

The following statements are true and correct:

      As of the date of this Agreement, the Company is engaged primarily in the
acquisition and operation of companies engaged in the distribution of fasteners
and provision of related inventory services.

      Executive is employed hereunder by the Company in a confidential
relationship wherein Executive, in the course of his employment with the
Company, has and will continue to become familiar with and aware of confidential
and proprietary information as to the Company's customers and specific manner of
doing business, including the processes, techniques and trade secrets utilized
by the Company, and future plans with respect thereto, all of which has been and
will be established and maintained at great expense to the Company. This
confidential and proprietary information is a trade secret and constitutes the
valuable goodwill of the Company.

      Therefore, in consideration of the mutual promises, terms, covenants and
conditions set forth herein and the performance of each, it is hereby agreed as
follows:

                                  AGREEMENTS

      1.    EMPLOYMENT AND DUTIES.

      (a) The Company hereby employs Executive as Chief Executive Officer of the
Company. As such, Executive shall have responsibilities, duties and authority
reasonably accorded to, expected of and consistent with Executive's position as
Chief Executive Officer of the Company and will report directly to the Board of
Directors of the Company (the "Board"). Executive hereby accepts this employment
upon the terms and conditions herein contained and, subject to paragraph 1(c),
agrees to devote substantially all of his business-related time, attention and
efforts to promote and further the business and interests of the Company and its
affiliates.

      (b) Executive shall faithfully adhere to all lawful policies established
by the Company.

                                     -1-
<PAGE>
      (c) Executive shall not, during the term of his employment hereunder, be
engaged in any other business activity pursued for gain, profit or other
pecuniary advantage if such activity interferes in any material respect with
Executive's duties and responsibilities hereunder. The foregoing limitations
shall not be construed as prohibiting Executive from (i) making personal
investments in such form or manner as will neither require his services in the
operation or affairs of the companies or enterprises in which such investments
are made nor violate the terms of paragraph 3 hereof; (ii) participating in
professional development activities; or (iii) acting as a director of not more
than one other corporation which does not compete with the Company provided such
representation does not adversely impact the Executive's duties hereunder.

      (d) Executive cannot be required by the Company to relocate unless the
Executive consents to such relocation. The Executive's refusal to relocate shall
not be considered "cause" for termination. Furthermore, Executive shall not be
required to commute to another location or travel extensively in lieu of
relocation.

      2. COMPENSATION. For all services rendered by Executive, the Company shall
compensate Executive beginning upon the consummation of the initial public
offering of the common stock of Pentacon (the "IPO") as follows:

      (a) BASE SALARY. The base salary payable to Executive shall be $150,000
per year commencing upon the consummation of the IPO, and payable on a regular
basis in accordance with the Company's standard payroll procedures but not less
than monthly. Such base salary may be increased (but not decreased) from time to
time, at the discretion of the Board, in light of Executive's annual review,
position, responsibilities and performance.

      (b) STOCK OPTION GRANT. Executive shall receive 185,000 options to
purchase shares of stock of the Company, exercisable at the price the stock is
issued in the IPO. Such options shall vest as follows: 30% shall vest at the end
of the second anniversary hereof and 100% shall vest at the end of the third
anniversary hereof.

      (c) BONUS. Executive shall receive an annual bonus to be determined by the
Board. Such bonus shall be targeted at 50% of Executive's base salary, subject
to yet to-be-determined performance criteria.

      (d) EXECUTIVE PERQUISITES, BENEFITS AND OTHER COMPENSATION. Executive
shall be entitled to receive additional benefits and compensation from the
Company in such form and to such extent as specified below:

            (i) Payment of all premiums for coverage for Executive and his
      dependent family members under health, hospitalization, disability,
      dental, life and other insurance plans that

                                     -2-
<PAGE>
      the Company may have in effect from time to time (all in an amount not
      less than such benefits provided to other Company executives).

            (ii) Reimbursement for all business travel and other out-of-pocket
      expenses and professional dues and fees reasonably incurred by Executive
      in the performance of his services pursuant to this Agreement. All
      reimbursable expenses shall be appropriately documented in reasonable
      detail by Executive upon submission of any request for reimbursement, and
      in a format and manner consistent with the Company's expense reporting
      policy.

            (iii) The Company shall provide Executive with other executive
      perquisites as may be available to or deemed appropriate for Executive by
      the Board and Executive shall be eligible for participation in all other
      Company-wide employee benefits as are available from time to time.

            (iv) The Executive shall be entitled to three weeks paid vacation
      per year.

      3.    NON-COMPETITION AGREEMENT.

      (a) Executive recognizes that the Company's willingness to enter into this
Agreement is based in material part on Executive's agreement to the provisions
of this paragraph 3 and that Executive's breach of the provisions of this
paragraph 3 could materially damage the Company. Subject to and so long as the
Company is not in violation of its obligations under this Agreement, Executive
will not, during the period of his employment by or with the Company, and for a
period of two (2) years immediately following the termination of his employment
under this Agreement, for any reason whatsoever (other than a termination by the
Company without cause, or a termination by Executive with Good Reason (as
hereinafter defined)), directly or indirectly, for himself or on behalf of or in
conjunction with any other person, company, partnership, corporation or business
of whatever nature:

            (i) engage, as an officer, director, shareholder, owner, partner,
      joint venturer, or in a managerial capacity, whether as an employee,
      independent contractor, consultant or advisor, or as a sales
      representative, in any business in direct competition with the Company or
      its subsidiaries, within one hundred (100) miles of where the Company or
      any of its subsidiaries conduct business, including any territory serviced
      by the Company or any of its subsidiaries (the "Territory");

            (ii) call upon any person who is, at that time, within the
      Territory, an employee of the Company or its subsidiaries (including the
      respective subsidiaries thereof) in a managerial capacity for the purpose
      or with the intent of enticing such employee away from or out of the
      employ of the Company or its subsidiaries;

                                     -3-
<PAGE>
            (iii) call upon any person or entity which is, at that time, or
      which has been, within one (1) year prior to that time, a customer of the
      Company or its subsidiaries within the Territory for the purpose of
      soliciting or selling products or services in direct competition with the
      Company or its subsidiaries within the Territory; or

            (iv) call upon any prospective acquisition candidate, on Executive's
      own behalf or on behalf of any competitor, which candidate was, to
      Executive's knowledge after due inquiry, either called upon by the Company
      or its subsidiaries or for which the Company or its subsidiaries made an
      acquisition analysis, for the purpose of acquiring such entity.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit Executive from acquiring as an investment not more than two percent
(2%) of the capital stock of a competing business, whose stock is traded on a
national securities exchange or on an over-the-counter or similar market.

      (b) Because of the difficulty of measuring economic losses to the Company
and its subsidiaries as a result of a breach of the foregoing covenant, and
because of the immediate and irreparable damage that could be caused to the
Company and its subsidiaries for which they would have no other adequate remedy,
Executive agrees that the foregoing covenant may be enforced by the Company or
its subsidiaries, in the event of breach by him, by injunctions and restraining
orders.

      (c) It is agreed by the parties that the foregoing covenants in this
paragraph 3 impose a reasonable restraint on Executive in light of the
activities and business of the Company or its subsidiaries, as the case may be,
on the date of the execution of this Agreement and the current plans of the
Company and its subsidiaries; but it is also the intent of the Company and
Executive that such covenants be construed and enforced in accordance with the
changing activities, business and locations of the Company and its subsidiaries,
as the case may be, throughout the term of this covenant, whether before or
after the date of termination of the employment of Executive. For example, if,
during the term of this Agreement, the Company or its subsidiaries, as the case
may be, engage in new and different activities, enter a new business or
establish new locations for their current activities or business in addition to
or other than the activities or business enumerated under the Recitals above or
the locations currently established therefor, then Executive will be precluded
from soliciting the customers or employees of such new activities or business or
from such new location and from directly competing with such new business within
100 miles of its then- established operating location(s) through the term of
this covenant.

      It is further agreed by the parties hereto that, in the event that
Executive shall cease to be employed hereunder, and shall enter into a business
or pursue other activities not in competition with the Company or its
subsidiaries, or similar activities or business in locations the operation of
which, under such circumstances, does not violate clause (a) of this paragraph
3, and in any event such new business, activities or location are not in
violation of this paragraph 3 or of Executive's obligations under this paragraph
3, if any, Executive shall not be chargeable with a violation of this paragraph

                                     -4-
<PAGE>
3 if the Company or its subsidiaries shall thereafter enter the same, similar or
a competitive (i) business, (ii) course of activities or (iii) location, as
applicable.

      (d) The covenants in this paragraph 3 are severable and separate, and the
unenforceability of any specific covenant shall not affect the provisions of any
other covenant. Moreover, in the event any court of competent jurisdiction shall
determine that the scope, time or territorial restrictions set forth are
unreasonable, then it is the intention of the parties that such restrictions be
enforced to the fullest extent which the court deems reasonable, and the
Agreement shall thereby be reformed.

      (e) All of the covenants in this paragraph 3 shall be construed as an
agreement independent of any other provision in this Agreement, and the
existence of any claim or cause of action of Executive against the Company or
its subsidiaries, whether predicated on this Agreement or otherwise, shall not
constitute a defense to the enforcement by the Company or its subsidiaries of
such covenants. It is specifically agreed that the period of two (2) years
following termination of employment stated at the beginning of this paragraph 3,
during which the agreements and covenants of Executive made in this paragraph 3
shall be effective, shall be computed by excluding from such computation any
time during which Executive is in violation of any provision of this paragraph
3.

      4. TERM; TERMINATION; RIGHTS ON TERMINATION. (a) The term of this
Agreement shall begin on the consummation of the IPO and continue for five (5)
years (the "Term"), and, unless terminated sooner as herein provided, shall
continue thereafter on a year-to-year basis on the same terms and conditions
contained herein in effect as of the time of renewal. This Agreement and
Executive's employment may be terminated in any one of the followings ways:

      (i) DEATH. The death of Executive shall immediately terminate this
Agreement with no severance compensation due to Executive's estate.

      (ii) DISABILITY. If, as a result of incapacity due to physical or mental
illness or injury, Executive shall have been absent from his full-time duties
hereunder for four (4) consecutive months, then thirty (30) days after receiving
written notice (which notice may occur before or after the end of such four (4)
month period, but which shall not be effective earlier than the last day of such
four (4) month period), the Company may terminate Executive's employment
hereunder, provided that Executive is unable to resume his full-time duties at
the conclusion of such notice period. Also, Executive may terminate his
employment hereunder if his health should become impaired to an extent that
makes the continued performance of his duties hereunder hazardous to his
physical or mental health or his life, provided that Executive shall have
furnished the Company with a written statement from a qualified doctor to such
effect and provided, further, that, at the Company's request made within thirty
(30) days of the date of such written statement, Executive shall submit to an
examination by a doctor selected by the Company who is reasonably acceptable to
Executive or Executive's doctor and such doctor shall have concurred in the
conclusion of

                                     -5-
<PAGE>
Executive's doctor. In the event this Agreement is terminated as a result of
Executive's disability, Executive shall receive from the Company, in a lump-sum
payment due within ten (10) days of the effective date of termination, the base
salary at the rate then in effect for whatever time period is remaining under
the Initial Term (as hereinafter defined) of this Agreement, provided that such
period shall not exceed one (1) year.

      (iii) GOOD CAUSE. The Company may terminate the Agreement ten (10) days
after written notice to Executive for good cause, which shall be: (i)
Executive's breach of any material provision of this Agreement (continuing for
ten (10) days after receipt of notice of need to cure); (ii) Executive's gross
negligence in the performance or intentional nonperformance (continuing for ten
(10) days after receipt of written notice of need to cure) of any of Executive's
material duties and responsibilities hereunder which is harmful or injurious to
the Company; (iii) Executive's dishonesty, fraud or misconduct with respect to
the business or affairs of the Company or its subsidiaries which materially and
adversely affects the operations or reputation of the Company or its
subsidiaries; (iv) Executive's conviction of a felony crime; or (v) alcohol
abuse or a confirmed positive illegal drug test result. In the event of a
termination for good cause, as enumerated above, Executive shall have no right
to any severance compensation but shall receive all compensation due and payable
through the date of termination.

      (iv) WITHOUT CAUSE. At any time after the commencement of employment,
Executive may, without cause, and without Good Reason terminate this Agreement
and Executive's employment, effective thirty (30) days after written notice is
provided to the Company. Executive may only be terminated without cause by the
Company during the Term hereof if such termination is approved by at least
eighty percent (80%) of the members of the Board of Directors of the Company.
Should Executive be terminated by the Company without cause or should Executive
terminate with Good Reason during the first three (3) years of the Term (the
"Initial Term"), Executive shall receive from the Company, in a lump-sum payment
due on the effective date of termination, the base salary at the rate then in
effect for whatever time period is remaining under the Initial Term of this
Agreement or for two (2) years, whichever amount is greater. Should Executive be
terminated by the Company without cause or should Executive terminate with Good
Reason after the Initial Term, Executive shall receive from the Company, in a
lump-sum payment due on the effective date of termination, the base salary at
the rate then in effect equivalent to one (1) year of salary. Further, any
termination without cause by the Company shall operate to shorten the period set
forth in paragraph 3(a) and during which the terms of paragraph 3 apply to one
(1) year from the date of termination of employment. If Executive resigns or
otherwise terminates his employment without cause, rather than the Company
terminating his employment pursuant to this paragraph 4(a)(iv), or if Executive
terminates without Good Reason, Executive shall receive no severance
compensation.

      Executive shall have "Good Reason" to terminate this Agreement and his
employment hereunder upon the occurrence of any of the following events: (a)
Executive experiences a reduction

                                     -6-
<PAGE>
in authority, responsibilities or duties to a position of less stature or
importance within the Company than the position described in paragraph 1 hereof
(b) a material breach of this Agreement by the Company which continues for
thirty (30) days after receipt of written notice of breach is received by the
Company from the Employee or (c) Executive is required to support (by action or
silence) conduct which constitutes dishonesty, fraud or willful misconduct with
respect to the business or affairs of the Company or its subsidiaries.

the Company or its subsidiaries, as the case may be, and be subject at all times
to their discretion and control. Likewise, all correspondence, reports, records,
charts, advertising materials and other similar data pertaining to the business,
activities or future plans of the Company or its subsidiaries which is collected
by Executive shall be delivered promptly to the Company without request by it
upon termination of Executive's employment.

      6. INVENTIONS. Executive shall disclose promptly to the Company any and
all significant conceptions and ideas for inventions, improvements and valuable
discoveries, whether patentable or not, which are conceived or made by
Executive, solely or jointly with another, during the period of employment, and
which are directly related to the business or activities of the Company and
which Executive conceives as a result of his employment by the Company.
Executive hereby assigns and agrees to assign all his interests therein to the
Company or its nominee. Whenever requested to do so by the Company, Executive
shall execute any and all applications, assignments or other instruments that
the Company shall deem necessary to apply for and obtain Letters Patent of the
United States or any foreign country or to otherwise protect the Company's
interest therein.

      7. TRADE SECRETS. Executive agrees that he will not, during or after the

Company's or its subsidiaries' relationships or agreements with their respective
significant vendors or customers or any other significant and material trade
secret of the Company or its subsidiaries, whether in existence or proposed, to
any person, firm, partnership, corporation or business for any reason or purpose

      (a) Executive acknowledges and agrees that all Confidential Information
(as defined below) of the Company is confidential and a valuable, special and
unique asset of the Company that gives the Company an advantage over its actual
and potential, current and future competitors. Executive further acknowledges
and agrees that Executive owes the Company a fiduciary duty to preserve and
protect all Confidential Information from unauthorized disclosure or
unauthorized use, that certain Confidential Information constitutes "trade
secrets" under applicable laws, and that unauthorized disclosure or unauthorized
use of the Company's Confidential Information would irreparably injure the
Company.

                                     -8-
<PAGE>
      (b) Both during the term of Executive's employment and after the
termination of Executive's employment for any reason (including wrongful
termination), Executive shall hold all Confidential Information in strict
confidence, and shall not use any Confidential Information except for the
benefit of the Company, in accordance with the duties assigned to Executive.
Executive shall not, at any time (either during or after the term of Executive's
employment), disclose any Confidential Information to any person or entity
(except other employees of the Company who have a need to know the information
in connection with the performance of their employment duties), or copy,
reproduce, modify, decompile or reverse engineer any Confidential Information,
or remove any Confidential Information from the Company's premises, without the
prior consent of the CEO of the Company or the Board of Directors of the Company
or permit any other person to do so. In the event Executive is requested or
required (by oral questions, interrogatories, requests for information or
documents, subpoena, civil investigative demand or other process) to disclose
any Confidential Information, Executive will provide the Company with immediate
written notice of any such request or requirement so that the Company may seek
an appropriate protective order and/or seek with Executive's cooperation to
narrow the request or demand or waive Executive's compliance with the provisions
of this Agreement. If, failing the entry of a protective order or the receipt of
a waiver hereunder, Executive is, in the opinion of his counsel, compelled to
disclose Confidential Information, Executive may disclose only that portion of
the Confidential Information which Executive's counsel advises Executive in
writing that Executive is compelled to disclose and Executive will exercise his
or her best efforts to obtain assurance that confidential treatment will be
accorded such Confidential Information. In any event, Executive will not oppose
action by the Company to obtain an appropriate protective order or other
reliable assurance that confidential treatment will be accorded the Confidential
Information. Executive shall take reasonable precautions to protect the physical
security of all documents and other material containing Confidential Information
(regardless of the medium on which the Confidential Information is stored). This
Agreement applies to all Confidential Information, whether now known or later to
become known to Executive.

      (c) Upon the termination of Executive's employment with the Company for
any reason, and upon request of the Company at any other time, Executive shall
promptly surrender and deliver to the Company all documents and other written
material of any nature containing or pertaining to any Confidential Information
and shall not retain any such document or other material. Within five days of
any such request, Executive shall certify to the Company in writing that all
such materials have been returned.

      (d) As used in this Agreement, the term "Confidential Information" shall
mean any information or material known to or used by or for the Company (whether
or not owned or developed by the Company and whether or not developed by
Executive) that is not generally known to the public. Confidential information
includes, but is not limited to, the following: all trade secrets of the
Company; all information that the Company has marked as confidential or has
otherwise described to Executive (either in writing or orally) as confidential;
all nonpublic information

                                     -9-

techniques, market studies, test data, customers, customer lists and records,

proprietary information belonging to the Company; all computer hardware or
software manual; all training or instruction manuals; and all data and all
computer system passwords and user codes.

      9. NO PRIOR AGREEMENTS. Executive hereby represents and warrants to the
Company that the execution of this Agreement by Executive and his employment by
the Company and the performance of his duties hereunder will not violate or be a
breach of any agreement with a former employer, client or any other person or
entity. Further, Executive agrees to indemnify the Company for any claim,
including, but not limited to, attorneys' fees and expenses of investigation, by
any such third party that such third party may now have or may hereafter come to
have against the Company based upon or arising out of any non-competition
agreement, invention or secrecy agreement between Executive and such third party
which was in existence as of the date of this Agreement.

      10. ASSIGNMENT; BINDING EFFECT. Executive understands that he has been
selected for employment by the Company on the basis of his personal
qualifications, experience and skills. Executive agrees, therefore, that he
cannot assign all or any portion of his performance under this Agreement.
Subject to the preceding two (2) sentences and the express provisions of
paragraph 11 below, this Agreement shall be binding upon, inure to the benefit
of and be enforceable by the parties hereto and their respective heirs, legal
representatives, successors and assigns.

      11.   CHANGE IN CONTROL.

      (a) Unless he elects to terminate this Agreement pursuant to subsections
b, c or d below, Executive understands and acknowledges that the Company may be
merged or consolidated with or into another entity and that such entity shall
automatically succeed to the rights and obligations of the Company hereunder or
that the Company may undergo another type of Change in Control. In the event
such a merger or consolidation or other Change in Control is initiated prior to
the end of the Term or any extension or renewal thereof, then the provisions of
this paragraph 11 shall be applicable.

      (b) In the event of a Change in Control wherein the Company and Executive
have not received written notice at least five (5) business days prior to the
date of the event giving rise to the Change in Control from the successor to all
or a substantial portion of the Company's business

                                     -10-
<PAGE>
and/or assets that such successor is willing as of the closing to assume and
agrees to perform the Company's obligations under this Agreement in the same
manner and to the same extent that the Company is hereby required to perform,
then Executive may, at Executive's sole discretion, elect to terminate
Executive's employment on such Change in Control by providing written notice to
the Company prior to the closing of the transaction giving rise to the Change in
Control. In such case, the applicable provisions of paragraph 4(a)(iv) will
apply as though the Company had terminated Executive without cause during the
Initial Term; however, the amount of the lump sum severance payment due
Executive pursuant to this paragraph 11(b) shall be triple the amount calculated
under the terms of paragraph 4(a)(iv), but shall in no event exceed four times
Executive's base salary.

      (c) In any Change in Control situation, Executive may, at Executive's sole
discretion, elect to terminate Executive's employment upon the effective date of
such Change in Control by providing written notice to the Company at least ten
(10) business days prior to the closing of the transaction (or ten (10) business
days after receipt of notice of such transaction, whichever is later) giving
rise to the Change in Control. In such case, the applicable provisions of
paragraph 4(a)(iv) will apply as though the Company had terminated Executive
without cause during the Initial Term; however, the amount of the lump sum
severance payment due Executive pursuant to this paragraph 11(c) shall be double
the amount calculated under the terms of paragraph 4(a)(iv), but shall in no
event exceed three times Executive's base salary.

      (d) If, on or within one year following the effective date of a Change in
Control the Company terminates Executive's employment other than for cause or if
Executive's employment with the Company is terminated by the Company within
three months before the effective date of a Change in Control other than for
cause and it is reasonably demonstrated that such termination (i) was at the
request of a third party that has taken steps reasonably calculated to effect a
Change in Control, or (ii) otherwise arose in connection with or anticipation of
a Change in Control, then Executive shall receive from Company, in a lump sum
payment due on the effective date of termination, the same amount which
Executive would have received pursuant to a termination under paragraph 11(b)
above.

      (e) Solely for purposes of applying paragraph 4 under the circumstances
described in (b) above, the effective date of termination will be the closing
date of the transaction giving rise to the Change in Control and all
compensation, reimbursements and lump-sum payments due Executive must be paid in
full by the Company at or prior to such closing.

      (f) A "Change in Control" shall be deemed to have occurred if:

            (i) any person, other than the Company or benefit plan of the
      Company, acquires, directly or indirectly, the beneficial ownership (as
      defined in Section 13(d) of the Securities Exchange Act of 1934, as
      amended) of any voting security of the Company and immediately after such
      acquisition such person is, directly or indirectly, the beneficial owner
      of voting

                                     -11-
<PAGE>
      securities representing thirty (30%) or more of the total voting power of
      all of the then-outstanding voting securities of the Company;

            (ii) the stockholders of the Company shall approve a merger,
      consolidation, recapitalization or reorganization of the Company, or a
      reverse stock split of outstanding voting securities, or consummation of
      any such transaction if stockholder approval is not obtained, other than
      any such transaction which would result in at least seventy-five (75%) of
      the total voting power represented by the voting securities of the
      surviving entity outstanding immediately after such transaction being
      beneficially owned by at least seventy-five (75%) of the holders of
      outstanding voting securities of the Company immediately prior to the
      transactions with the voting power of each such continuing holder relative
      to other such continuing holders not substantially altered in the
      transaction; or

            (iii) the stockholders of the Company shall approve a plan of
      complete liquidation of the Company or an agreement for the sale or
      disposition by the Company of all or a substantial portion of the
      Company's assets (i.e., fifty (50%) or more of the total assets of the
      Company).

      (g) Executive shall be fully "grossed up" by the Company or its successor
for any excise taxes that Executive incurs under Section 4999 of the Internal
Revenue Code of 1986 (as well as for income tax on the "gross up" amount, as a
result of any Change in Control. Such amount will be due and payable by the
Company on the date of the Change of Control.

      (h) Upon the occurrence of a Change of Control, any unvested portion of
any awards of stock options or stock grants pursuant to this Agreement or
otherwise shall immediately vest and become exercisable to their fullest extent
(notwithstanding any vesting periods specified elsewhere) and Executive shall be
entitled to all rights and privileges associated with such awards (subject to
applicable securities laws and regulations). With respect to option awards which
vest pursuant to this paragraph, Executive shall have a period of twelve (12)
months from the date of vesting in which to exercise such options.

      12. COMPLETE AGREEMENT. This Agreement is not a promise of future
employment. Executive has no oral representations, understandings or agreements
with the Company or any of its officers, directors or representatives covering
the same subject matter as this Agreement. This written Agreement is the final,
complete and exclusive statement and expression of the agreement between the
Company and Executive and of all the terms of this Agreement, and it cannot be

oral or written agreements. This written Agreement may not be later modified
except by a further writing signed by a duly authorized officer of the Company
and Executive, and no term of this Agreement may be waived except by a writing

                    GENERAL COUNSEL'S EMPLOYMENT AGREEMENT

      This Employment Agreement (the "Agreement") by and between Pentacon, Inc.,
a Delaware corporation (the "Company"), and Bruce M. Taten ("Executive") is
hereby entered into and effective as of the 2nd day of December, 1997. This
Agreement hereby supersedes any other employment agreements or understandings,
written or oral, between the Company and Executive.

                                   RECITALS

The following statements are true and correct:

      As of the date of this Agreement, the Company is engaged primarily in the
acquisition and operation of companies engaged in the distribution of fasteners
and provision of related inventory services.

      Executive is employed hereunder by the Company in a confidential
relationship wherein Executive, in the course of his employment with the
Company, has and will continue to become familiar with and aware of confidential
and proprietary information as to the Company's customers and specific manner of
doing business, including the processes, techniques and trade secrets utilized
by the Company, and future plans with respect thereto, all of which has been and
will be established and maintained at great expense to the Company. This
confidential and proprietary information is a trade secret and constitutes the
valuable goodwill of the Company.

      Therefore, in consideration of the mutual promises, terms, covenants and
conditions set forth herein and the performance of each, it is hereby agreed as
follows:

                                  AGREEMENTS

      1.    EMPLOYMENT AND DUTIES.

      (a) The Company hereby employs Executive as Senior Vice President, Chief
Administrative Officer, General Counsel and Secretary of the Company. As such,
Executive shall have responsibilities, duties and authority reasonably accorded
to, expected of and consistent with Executive's position as Senior Vice
President, Chief Administrative Officer, General Counsel, and Secretary of the
Company and will report directly to the Chief Executive Officer of the Company
(the "CEO"). Executive hereby accepts this employment upon the terms and
conditions herein contained and, subject to paragraph 1(c), agrees to devote
substantially all of his business-related time, attention and efforts to promote
and further the business and interests of the Company and its affiliates.

      (b) Executive shall faithfully adhere to all lawful policies established
by the Company.

                                     -1-
<PAGE>
      (c) Executive shall not, during the term of his employment hereunder, be
engaged in any other business activity pursued for gain, profit or other
pecuniary advantage if such activity interferes in any material respect with
Executive's duties and responsibilities hereunder. The foregoing limitations
shall not be construed as prohibiting Executive from (i) making personal
investments in such form or manner as will neither require his services in the
operation or affairs of the companies or enterprises in which such investments
are made nor violate the terms of paragraph 3 hereof; (ii) participating in
professional development activities; or (iii) acting as a director of not more
than one other corporation which does not compete with the Company provided such
representation does not adversely impact the Executive's duties hereunder.

      (d) Executive cannot be required by the Company to relocate unless the
Executive consents to such relocation. The Executive's refusal to relocate shall
not be considered "cause" for termination. Furthermore, Executive shall not be
required to commute to another location or travel extensively in lieu of
relocation.

      2. COMPENSATION. For all services rendered by Executive, the Company shall
compensate Executive beginning upon the consummation of the initial public
offering of the common stock of Pentacon (the "IPO") as follows:

      (a) BASE SALARY. The base salary payable to Executive shall be $150,000
per year commencing upon the consummation of the IPO, and payable on a regular
basis in accordance with the Company's standard payroll procedures but not less
than monthly. Such base salary may be increased (but not decreased) from time to
time, at the discretion of the Board of Directors of Pentacon ("the Board"), in
light of Executive's annual review, position, responsibilities and performance.

      (b) STOCK OPTION GRANT. Executive shall receive 100,000 options to
purchase shares of stock of the Company, exercisable at the price the stock is
issued in the IPO. Such options shall vest as follows: 30% shall vest at the end
of the second anniversary hereof and 100% shall vest at the end of the third
anniversary hereof.

      (c) BONUS. Executive shall receive an annual bonus to be determined by the
Board. Such bonus shall be targeted at 30% of Executive's base salary, subject
to yet to-be-determined performance criteria.

      (d) EXECUTIVE PERQUISITES, BENEFITS AND OTHER COMPENSATION. Executive
shall be entitled to receive additional benefits and compensation from the
Company in such form and to such extent as specified below:

            (i) Payment of all premiums for coverage for Executive and his
      dependent family members under health, hospitalization, disability,
      dental, life and other insurance plans that

                                     -2-
<PAGE>
      the Company may have in effect from time to time (all in an amount not
      less than such benefits provided to other Company executives).

            (ii) Reimbursement for all business travel and other out-of-pocket
      expenses and professional dues and fees reasonably incurred by Executive
      in the performance of his services pursuant to this Agreement. All
      reimbursable expenses shall be appropriately documented in reasonable
      detail by Executive upon submission of any request for reimbursement, and
      in a format and manner consistent with the Company's expense reporting
      policy.

            (iii) The Company shall provide Executive with other executive
      perquisites as may be available to or deemed appropriate for Executive by
      the Board and Executive shall be eligible for participation in all other
      Company-wide employee benefits as are available from time to time.

            (iv) The Executive shall be entitled to three weeks paid vacation
per year.

      3.    NON-COMPETITION AGREEMENT.

      (a) Executive recognizes that the Company's willingness to enter into this
Agreement is based in material part on Executive's agreement to the provisions
of this paragraph 3 and that Executive's breach of the provisions of this
paragraph 3 could materially damage the Company. Subject to and so long as the
Company is not in violation of its obligations under this Agreement, Executive
will not, during the period of his employment by or with the Company, and for a
period of two (2) years immediately following the termination of his employment
under this Agreement, for any reason whatsoever (other than a termination by the
Company without cause, or a termination by Executive with Good Reason (as
hereinafter defined)), directly or indirectly, for himself or on behalf of or in
conjunction with any other person, company, partnership, corporation or business
of whatever nature:

            (i) engage, as an officer, director, shareholder, owner, partner,
      joint venturer, or in a managerial capacity, whether as an employee,
      independent contractor, consultant or advisor, or as a sales
      representative, in any business in direct competition with the Company or
      its subsidiaries, within one hundred (100) miles of where the Company or
      any of its subsidiaries conduct business, including any territory serviced
      by the Company or any of its subsidiaries (the "Territory");

            (ii) call upon any person who is, at that time, within the
      Territory, an employee of the Company or its subsidiaries (including the
      respective subsidiaries thereof) in a managerial capacity for the purpose
      or with the intent of enticing such employee away from or out of the
      employ of the Company or its subsidiaries;

                                     -3-
<PAGE>
            (iii) call upon any person or entity which is, at that time, or
      which has been, within one (1) year prior to that time, a customer of the
      Company or its subsidiaries within the Territory for the purpose of
      soliciting or selling products or services in direct competition with the
      Company or its subsidiaries within the Territory; or

            (iv) call upon any prospective acquisition candidate, on Executive's
      own behalf or on behalf of any competitor, which candidate was, to
      Executive's knowledge after due inquiry, either called upon by the Company
      or its subsidiaries or for which the Company or its subsidiaries made an
      acquisition analysis, for the purpose of acquiring such entity.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit Executive from acquiring as an investment not more than two percent
(2%) of the capital stock of a competing business, whose stock is traded on a
national securities exchange or on an over-the-counter or similar market.

      (b) Because of the difficulty of measuring economic losses to the Company
and its subsidiaries as a result of a breach of the foregoing covenant, and
because of the immediate and irreparable damage that could be caused to the
Company and its subsidiaries for which they would have no other adequate remedy,
Executive agrees that the foregoing covenant may be enforced by the Company or
its subsidiaries, in the event of breach by him, by injunctions and restraining
orders.

      (c) It is agreed by the parties that the foregoing covenants in this
paragraph 3 impose a reasonable restraint on Executive in light of the
activities and business of the Company or its subsidiaries, as the case may be,
on the date of the execution of this Agreement and the current plans of the
Company and its subsidiaries; but it is also the intent of the Company and
Executive that such covenants be construed and enforced in accordance with the
changing activities, business and locations of the Company and its subsidiaries,
as the case may be, throughout the term of this covenant, whether before or
after the date of termination of the employment of Executive. For example, if,
during the term of this Agreement, the Company or its subsidiaries, as the case
may be, engage in new and different activities, enter a new business or
establish new locations for their current activities or business in addition to
or other than the activities or business enumerated under the Recitals above or
the locations currently established therefor, then Executive will be precluded
from soliciting the customers or employees of such new activities or business or
from such new location and from directly competing with such new business within
100 miles of its then- established operating location(s) through the term of
this covenant.

      It is further agreed by the parties hereto that, in the event that
Executive shall cease to be employed hereunder, and shall enter into a business
or pursue other activities not in competition with the Company or its
subsidiaries, or similar activities or business in locations the operation of
which, under such circumstances, does not violate clause (a) of this paragraph
3, and in any event such new business, activities or location are not in
violation of this paragraph 3 or of Executive's obligations

                                     -4-
<PAGE>
under this paragraph 3, if any, Executive shall not be chargeable with a
violation of this paragraph 3 if the Company or its subsidiaries shall
thereafter enter the same, similar or a competitive (i) business, (ii) course of
activities or (iii) location, as applicable.

      (d) The covenants in this paragraph 3 are severable and separate, and the
unenforceability of any specific covenant shall not affect the provisions of any
other covenant. Moreover, in the event any court of competent jurisdiction shall
determine that the scope, time or territorial restrictions set forth are
unreasonable, then it is the intention of the parties that such restrictions be
enforced to the fullest extent which the court deems reasonable, and the
Agreement shall thereby be reformed.

      (e) All of the covenants in this paragraph 3 shall be construed as an
agreement independent of any other provision in this Agreement, and the
existence of any claim or cause of action of Executive against the Company or
its subsidiaries, whether predicated on this Agreement or otherwise, shall not
constitute a defense to the enforcement by the Company or its subsidiaries of
such covenants. It is specifically agreed that the period of two (2) years
following termination of employment stated at the beginning of this paragraph 3,
during which the agreements and covenants of Executive made in this paragraph 3
shall be effective, shall be computed by excluding from such computation any
time during which Executive is in violation of any provision of this paragraph
3.

      4. TERM; TERMINATION; RIGHTS ON TERMINATION. (a) The term of this
Agreement shall begin on the consummation of the IPO and continue for three (3)
years (the "Term"), and, unless terminated sooner as herein provided, shall
continue thereafter on a year-to-year basis on the same terms and conditions
contained herein in effect as of the time of renewal. This Agreement and
Executive's employment may be terminated in any one of the followings ways:

      (i) DEATH. The death of Executive shall immediately terminate this
Agreement with no severance compensation due to Executive's estate.

      (ii) DISABILITY. If, as a result of incapacity due to physical or mental
illness or injury, Executive shall have been absent from his full-time duties
hereunder for four (4) consecutive months, then thirty (30) days after receiving
written notice (which notice may occur before or after the end of such four (4)
month period, but which shall not be effective earlier than the last day of such
four (4) month period), the Company may terminate Executive's employment
hereunder, provided that Executive is unable to resume his full-time duties at
the conclusion of such notice period. Also, Executive may terminate his
employment hereunder if his health should become impaired to an extent that
makes the continued performance of his duties hereunder hazardous to his
physical or mental health or his life, provided that Executive shall have
furnished the Company with a written statement from a qualified doctor to such
effect and provided, further, that, at the Company's request made within thirty
(30) days of the date of such written statement, Executive shall submit to an
examination by a doctor selected by the Company who is reasonably acceptable

                                     -5-
<PAGE>
to Executive or Executive's doctor and such doctor shall have concurred in the
conclusion of Executive's doctor. In the event this Agreement is terminated as a
result of Executive's disability, Executive shall receive from the Company, in a
lump-sum payment due within ten (10) days of the effective date of termination,
the base salary at the rate then in effect for whatever time period is remaining
under the Initial Term (as hereinafter defined) of this Agreement, provided that
such period shall not exceed one (1) year.

      (iii) GOOD CAUSE. The Company may terminate the Agreement ten (10) days
after written notice to Executive for good cause, which shall be: (i)
Executive's breach of any material provision of this Agreement (continuing for
ten (10) days after receipt of notice of need to cure); (ii) Executive's gross
negligence in the performance or intentional nonperformance (continuing for ten
(10) days after receipt of written notice of need to cure) of any of Executive's
material duties and responsibilities hereunder which is harmful or injurious to
the Company; (iii) Executive's dishonesty, fraud or misconduct with respect to
the business or affairs of the Company or its subsidiaries which materially and
adversely affects the operations or reputation of the Company or its
subsidiaries; (iv) Executive's conviction of a felony crime; or (v) alcohol
abuse or a confirmed positive illegal drug test result. In the event of a
termination for good cause, as enumerated above, Executive shall have no right
to any severance compensation but shall receive all compensation due and payable
through the date of termination.

      (iv) WITHOUT CAUSE. At any time after the commencement of employment,
Executive may, without cause, and without Good Reason terminate this Agreement
and Executive's employment, effective thirty (30) days after written notice is
provided to the Company. Executive may only be terminated without cause by the
Company during the Term hereof if such termination is approved by at least
eighty percent (80%) of the members of the Board of Directors of the Company.
Should Executive be terminated by the Company without cause or should Executive
terminate with Good Reason during the first three (3) years of the Term (the
"Initial Term"), Executive shall receive from the Company, in a lump-sum payment
due on the effective date of termination, the base salary at the rate then in
effect for whatever time period is remaining under the Initial Term of this
Agreement or for two (2) years, whichever amount is greater. Should Executive be
terminated by the Company without cause or should Executive terminate with Good
Reason after the Initial Term, Executive shall receive from the Company, in a
lump-sum payment due on the effective date of termination, the base salary at
the rate then in effect equivalent to one (1) year of salary. Further, any
termination without cause by the Company shall operate to shorten the period set
forth in paragraph 3(a) and during which the terms of paragraph 3 apply to one
(1) year from the date of termination of employment. If Executive resigns or
otherwise terminates his employment without cause, rather than the Company
terminating his employment pursuant to this paragraph 4(a)(iv), or if Executive
terminates without Good Reason, Executive shall receive no severance
compensation.

                                     -6-
<PAGE>
      Executive shall have "Good Reason" to terminate this Agreement and his
employment hereunder upon the occurrence of any of the following events: (a)
Executive experiences a reduction in authority, responsibilities or duties to a
position of less stature or importance within the Company than the position
described in paragraph 1 hereof (b) a material breach of this Agreement by the
Company which continues for thirty (30) days after receipt of written notice of
breach is received by the Company from the Employee or (c) Executive is required
to support (by action or silence) conduct which constitutes dishonesty, fraud or
willful misconduct with respect to the business or affairs of the Company or its
subsidiaries.

      Upon termination of this Agreement for any reason provided above,
Executive shall be entitled to receive all compensation earned and/or accrued
and all benefits and reimbursements due and/or accrued through the effective
date of termination. Additional compensation subsequent to termination, if any,
will be due and payable to Executive only to the extent and in the manner
expressly provided above or in paragraph 11. All other rights and obligations of
the Company and Executive under this Agreement shall cease as of the effective
date of termination, except that the Executive's obligations under paragraphs 3,
5, 6, 7, 8 and 9 herein and the Company's obligations with respect to stock
grants, stock options, and severance shall survive such termination in
accordance with their terms.

      (b) CHANGE IN CONTROL OF THE COMPANY. In the event of a "Change in
Control" of the Company (as defined below) during the Term or any extension or
renewal thereof, refer to paragraph 11 below.

portion of any awards of stock options or stock grants pursuant to this
Agreement in connection with Executive's employment shall be treated in the
following manner in the event of a termination of Executive's employment.

            (i) If Executive's employment is terminated by the Company for cause
      or if Executive resigns or terminates his employment other than for Good
      Reason, then any unvested portion of any awards of stock options or stock
      grants shall lapse or shall be forfeited.

            (ii) If Executive's employment is terminated by the Company without
      cause or if Executive terminates his employment for Good Reason, then any
      unvested portion of any awards of stock options or stock grants shall
      immediately vest to their fullest extent (notwithstanding any vesting
      provisions to the contrary) and Executive shall be entitled to all rights
      and privileges associated with such awards (subject to applicable
      securities laws and regulations).

                                     -7-
<PAGE>
            (iii) If Executive's employment is terminated pursuant to a "Change
      in Control," then the stock options and stock awards shall be treated in
      the manner provided in paragraph 11 hereof.

      5. RETURN OF COMPANY PROPERTY. All records, designs, patents, business
plans, financial statements, manuals, memoranda, lists and other property
delivered to or compiled by Executive by or on behalf of the Company, its
subsidiaries or their representatives, vendors or customers which pertain to the
business of the Company or its subsidiaries shall be and remain the property of
the Company or its subsidiaries, as the case may be, and be subject at all times
to their discretion and control. Likewise, all correspondence, reports, records,
charts, advertising materials and other similar data pertaining to the business,
activities or future plans of the Company or its subsidiaries which is collected
by Executive shall be delivered promptly to the Company without request by it
upon termination of Executive's employment.

      6. INVENTIONS. Executive shall disclose promptly to the Company any and
all significant conceptions and ideas for inventions, improvements and valuable
discoveries, whether patentable or not, which are conceived or made by
Executive, solely or jointly with another, during the period of employment, and
which are directly related to the business or activities of the Company and
which Executive conceives as a result of his employment by the Company.
Executive hereby assigns and agrees to assign all his interests therein to the
Company or its nominee. Whenever requested to do so by the Company, Executive
shall execute any and all applications, assignments or other instruments that
the Company shall deem necessary to apply for and obtain Letters Patent of the
United States or any foreign country or to otherwise protect the Company's
interest therein.

      7. TRADE SECRETS. Executive agrees that he will not, during or after the
Term of this Agreement with the Company, disclose the specific terms of the
Company's or its subsidiaries' relationships or agreements with their respective
significant vendors or customers or any other significant and material trade
secret of the Company or its subsidiaries, whether in existence or proposed, to
any person, firm, partnership, corporation or business for any reason or purpose
whatsoever, except in connection with (a) any legal proceeding of the Company in
which such disclosure is required to be made by the Company (b) obtaining the
advice of outside consultants engaged by the Company (c) discussions with the
Company's outside auditors (d) obtaining or maintenance of the Company's credit
facility or (e) otherwise with the consent of the Company's CEO or the Board of
Directors.

      8.    CONFIDENTIALITY.

      (a) Executive acknowledges and agrees that all Confidential Information
(as defined below) of the Company is confidential and a valuable, special and
unique asset of the Company that gives the Company an advantage over its actual
and potential, current and future competitors. Executive further acknowledges
and agrees that Executive owes the Company a fiduciary duty to

                                     -8-
<PAGE>
preserve and protect all Confidential Information from unauthorized disclosure
or unauthorized use, that certain Confidential Information constitutes "trade
secrets" under applicable laws, and that unauthorized disclosure or unauthorized
use of the Company's Confidential Information would irreparably injure the
Company.

      (b) Both during the term of Executive's employment and after the
termination of Executive's employment for any reason (including wrongful
termination), Executive shall hold all Confidential Information in strict
confidence, and shall not use any Confidential Information except for the
benefit of the Company, in accordance with the duties assigned to Executive.
Executive shall not, at any time (either during or after the term of Executive's
employment), disclose any Confidential Information to any person or entity
(except other employees of the Company who have a need to know the information
in connection with the performance of their employment duties), or copy,
reproduce, modify, decompile or reverse engineer any Confidential Information,
or remove any Confidential Information from the Company's premises, without the
prior consent of the CEO of the Company or the Board of Directors of the
Company, or permit any other person to do so. In the event Executive is
requested or required (by oral questions, interrogatories, requests for
information or documents, subpoena, civil investigative demand or other process)
to disclose any Confidential Information, Executive will provide the Company
with immediate written notice of any such request or requirement so that the
Company may seek an appropriate protective order and/or seek with Executive's
cooperation to narrow the request or demand or waive Executive's compliance with
the provisions of this Agreement. If, failing the entry of a protective order or
the receipt of a waiver hereunder, Executive is, in the opinion of his counsel,
compelled to disclose Confidential Information, Executive may disclose only that
portion of the Confidential Information which Executive's counsel advises
Executive in writing that Executive is compelled to disclose and Executive will
exercise his or her best efforts to obtain assurance that confidential treatment
will be accorded such Confidential Information. In any event, Executive will not
oppose action by the Company to obtain an appropriate protective order or other
reliable assurance that confidential treatment will be accorded the Confidential
Information. Executive shall take reasonable precautions to protect the physical
security of all documents and other material containing Confidential Information
(regardless of the medium on which the Confidential Information is stored). This
Agreement applies to all Confidential Information, whether now known or later to
become known to Executive.

      (c) Upon the termination of Executive's employment with the Company for
any reason, and upon request of the Company at any other time, Executive shall
promptly surrender and deliver to the Company all documents and other written
material of any nature containing or pertaining to any Confidential Information
and shall not retain any such document or other material. Within five days of
any such request, Executive shall certify to the Company in writing that all
such materials have been returned.

                                     -9-
<PAGE>
      (d) As used in this Agreement, the term "Confidential Information" shall
mean any information or material known to or used by or for the Company (whether
or not owned or developed by the Company and whether or not developed by
Executive) that is not generally known to the public. Confidential information
includes, but is not limited to, the following: all trade secrets of the
Company; all information that the Company has marked as confidential or has
otherwise described to Executive (either in writing or orally) as confidential;
all nonpublic information concerning the Company's products, services,
prospective products or services, research, product designs, prices, discounts,
costs, marketing plans, marketing techniques, market studies, test data,
customers, customer lists and records, suppliers and contracts; all Company
business records and plans; all Company personnel files; all financial
information of or concerning the Company; all information relating to operating
system software, application software, software and system methodology, hardware
platforms, technical information, inventions, computer programs and listings,
source codes, object codes, copyrights and other intellectual property; all
technical specifications; any proprietary information belonging to the Company;
all computer hardware or software manual; all training or instruction manuals;
and all data and all computer system passwords and user codes.

      9. NO PRIOR AGREEMENTS. Executive hereby represents and warrants to the
Company that the execution of this Agreement by Executive and his employment by
the Company and the performance of his duties hereunder will not violate or be a
breach of any agreement with a former employer, client or any other person or
entity. Further, Executive agrees to indemnify the Company for any claim,
including, but not limited to, attorneys' fees and expenses of investigation, by
any such third party that such third party may now have or may hereafter come to
have against the Company based upon or arising out of any non-competition
agreement, invention or secrecy agreement between Executive and such third party
which was in existence as of the date of this Agreement.

      10. ASSIGNMENT; BINDING EFFECT. Executive understands that he has been
selected for employment by the Company on the basis of his personal
qualifications, experience and skills. Executive agrees, therefore, that he
cannot assign all or any portion of his performance under this Agreement.
Subject to the preceding two (2) sentences and the express provisions of
paragraph 11 below, this Agreement shall be binding upon, inure to the benefit
of and be enforceable by the parties hereto and their respective heirs, legal
representatives, successors and assigns.

      11.   CHANGE IN CONTROL.

      (a) Unless he elects to terminate this Agreement pursuant to subsections
b, c or d below, Executive understands and acknowledges that the Company may be
merged or consolidated with or into another entity and that such entity shall
automatically succeed to the rights and obligations of the Company hereunder or
that the Company may undergo another type of Change in Control. In the event
such a merger or consolidation or other Change in Control is initiated prior to
the end

                                     -10-
<PAGE>
of the Term or any extension or renewal thereof, then the provisions of this
paragraph 11 shall be applicable.

      (b) In the event of a Change in Control wherein the Company and Executive
have not received written notice at least five (5) business days prior to the
date of the event giving rise to the Change in Control from the successor to all
or a substantial portion of the Company's business and/or assets that such
successor is willing as of the closing to assume and agrees to perform the
Company's obligations under this Agreement in the same manner and to the same
extent that the Company is hereby required to perform, then Executive may, at
Executive's sole discretion, elect to terminate Executive's employment on such
Change in Control by providing written notice to the Company prior to the
closing of the transaction giving rise to the Change in Control. In such case,
the applicable provisions of paragraph 4(a)(iv) will apply as though the Company
had terminated Executive without cause during the Initial Term; however, the
amount of the lump sum severance payment due Executive pursuant to this
paragraph 11(b) shall be triple the amount calculated under the terms of
paragraph 4(a)(iv), but shall in no event exceed four times Executive's base
salary.

      (c) In any Change in Control situation, Executive may, at Executive's sole
discretion, elect to terminate Executive's employment upon the effective date of
such Change in Control by providing written notice to the Company at least ten
(10) business days prior to the closing of the transaction (or ten (10) business
days after receipt of notice of such transaction, whichever is later) giving
rise to the Change in Control. In such case, the applicable provisions of
paragraph 4(a)(iv) will apply as though the Company had terminated Executive
without cause during the Initial Term; however, the amount of the lump sum
severance payment due Executive pursuant to this paragraph 11(c) shall be double
the amount calculated under the terms of paragraph 4(a)(iv), but shall in no
event exceed three times Executive's base salary.

      (d) If, on or within one year following the effective date of a Change in
Control the Company terminates Executive's employment other than for cause or if
Executive's employment with the Company is terminated by the Company within
three months before the effective date of a Change in Control other than for
cause and it is reasonably demonstrated that such termination (i) was at the
request of a third party that has taken steps reasonably calculated to effect a
Change in Control, or (ii) otherwise arose in connection with or anticipation of
a Change in Control, then Executive shall receive from Company, in a lump sum
payment due on the effective date of termination, the same amount which
Executive would have received pursuant to a termination under paragraph 11(b)
above.

      (e) Solely for purposes of applying paragraph 4 under the circumstances
described in (b) above, the effective date of termination will be the closing
date of the transaction giving rise to the Change in Control and all
compensation, reimbursements and lump-sum payments due Executive must be paid in
full by the Company at or prior to such closing.

                                     -11-
<PAGE>
      (f) A "Change in Control" shall be deemed to have occurred if:

            (i) any person, other than the Company or benefit plan of the
      Company, acquires, directly or indirectly, the beneficial ownership (as
      defined in Section 13(d) of the Securities Exchange Act of 1934, as
      amended) of any voting security of the Company and immediately after such
      acquisition such person is, directly or indirectly, the beneficial owner
      of voting securities representing thirty (30%) or more of the total voting
      power of all of the then-outstanding voting securities of the Company;

            (ii) the stockholders of the Company shall approve a merger,
      consolidation, recapitalization or reorganization of the Company, or a
      reverse stock split of outstanding voting securities, or consummation of
      any such transaction if stockholder approval is not obtained, other than
      any such transaction which would result in at least seventy-five (75%) of
      the total voting power represented by the voting securities of the
      surviving entity outstanding immediately after such transaction being
      beneficially owned by at least seventy-five (75%) of the holders of
      outstanding voting securities of the Company immediately prior to the
      transactions with the voting power of each such continuing holder relative
      to other such continuing holders not substantially altered in the
      transaction; or

            (iii) the stockholders of the Company shall approve a plan of
      complete liquidation of the Company or an agreement for the sale or
      disposition by the Company of all or a substantial portion of the
      Company's assets (i.e., fifty (50%) or more of the total assets of the
      Company).

      (g) Executive shall be fully "grossed up" by the Company or its successor
for any excise taxes that Executive incurs under Section 4999 of the Internal
Revenue Code of 1986 (as well as for income tax on the "gross up" amount, as a
result of any Change in Control. Such amount will be due and payable by the
Company on the date of the Change of Control.

      (h) Upon the occurrence of a Change of Control, any unvested portion of
any awards of stock options or stock grants pursuant to this Agreement or
otherwise shall immediately vest and become exercisable to their fullest extent
(notwithstanding any vesting periods specified elsewhere) and Executive shall be
entitled to all rights and privileges associated with such awards (subject to
applicable securities laws and regulations). With respect to option awards which
vest pursuant to this paragraph, Executive shall have a period of twelve (12)
months from the date of vesting in which to exercise such options.

      12. COMPLETE AGREEMENT. This Agreement is not a promise of future
employment. Executive has no oral representations, understandings or agreements
with the Company or any of its officers, directors or representatives covering
the same subject matter as this Agreement. This written Agreement is the final,
complete and exclusive statement and expression of the agreement

                                     -12-
<PAGE>
between the Company and Executive and of all the terms of this Agreement, and it
cannot be varied, contradicted or supplemented by evidence of any prior or
contemporaneous oral or written agreements. This written Agreement may not be
later modified except by a further writing signed by a duly authorized officer

by a writing signed by the party waiving the benefit of such Term.

valid and operative and, so far as is reasonable and possible, effect shall be
given to the intent manifested by the portion held invalid or inoperative. The

                CHIEF FINANCIAL OFFICER'S EMPLOYMENT AGREEMENT

      This Employment Agreement (the "Agreement") by and between Pentacon, Inc.,
a Delaware corporation (the "Company"), and Brian Fontana ("Executive") is
hereby entered into and effective as of the 2nd day of December, 1997. This
Agreement hereby supersedes any other employment agreements or understandings,
written or oral, between the Company and Executive.

                                   RECITALS

The following statements are true and correct:

      As of the date of this Agreement, the Company is engaged primarily in the
acquisition and operation of companies engaged in the distribution of fasteners
and provision of related inventory services.

      Executive is employed hereunder by the Company in a confidential
relationship wherein Executive, in the course of his employment with the
Company, has and will continue to become familiar with and aware of confidential
and proprietary information as to the Company's customers and specific manner of
doing business, including the processes, techniques and trade secrets utilized
by the Company, and future plans with respect thereto, all of which has been and
will be established and maintained at great expense to the Company. This
confidential and proprietary information is a trade secret and constitutes the
valuable goodwill of the Company.

      Therefore, in consideration of the mutual promises, terms, covenants and
conditions set forth herein and the performance of each, it is hereby agreed as
follows:

                                  AGREEMENTS

      1.    EMPLOYMENT AND DUTIES.

      (a) The Company hereby employs Executive as Chief Financial Officer of the
Company. As such, Executive shall have responsibilities, duties and authority
reasonably accorded to, expected of and consistent with Executive's position as
Chief Financial Officer of the Company and will report directly to the Chief
Executive Officer of the Company (the "CEO"). Executive hereby accepts this
employment upon the terms and conditions herein contained and, subject to
paragraph 1(c), agrees to devote substantially all of his business-related time,
attention and efforts to promote and further the business and interests of the
Company and its affiliates.

      (b) Executive shall faithfully adhere to all lawful policies established
by the Company.

                                     -1-
<PAGE>
      (c) Executive shall not, during the term of his employment hereunder, be
engaged in any other business activity pursued for gain, profit or other
pecuniary advantage if such activity interferes in any material respect with
Executive's duties and responsibilities hereunder. The foregoing limitations
shall not be construed as prohibiting Executive from (i) making personal
investments in such form or manner as will neither require his services in the
operation or affairs of the companies or enterprises in which such investments
are made nor violate the terms of paragraph 3 hereof; (ii) participating in
professional development activities; or (iii) acting as a director of not more
than one other corporation which does not compete with the Company provided such
representation does not adversely impact the Executive's duties hereunder.

      (d) Executive cannot be required by the Company to relocate unless the
Executive consents to such relocation. The Executive's refusal to relocate shall
not be considered "cause" for termination. Furthermore, Executive shall not be
required to commute to another location or travel extensively in lieu of
relocation.

      2. COMPENSATION. For all services rendered by Executive, the Company shall
compensate Executive beginning upon the consummation of the initial public
offering of the common stock of Pentacon (the "IPO") as follows:

      (a) BASE SALARY. The base salary payable to Executive shall be $150,000
per year commencing upon the consummation of the IPO, and payable on a regular
basis in accordance with the Company's standard payroll procedures but not less
than monthly. Such base salary may be increased (but not decreased) from time to
time, at the discretion of the Board of Directors of the Company (the "Board"),
in light of Executive's annual review, position, responsibilities and
performance.

      (b) STOCK OPTION GRANT. Executive shall receive 85,000 options to purchase
shares of stock of the Company, exercisable at the price the stock is issued in
the IPO. Such options shall vest as follows: 30% shall vest at the end of the
second anniversary hereof and 100% shall vest at the end of the third
anniversary hereof.

      (c) BONUS. Executive shall receive an annual bonus to be determined by the
Board. Such bonus shall be targeted at 30% of Executive's base salary, subject
to yet to-be-determined performance criteria.

      (d) EXECUTIVE PERQUISITES, BENEFITS AND OTHER COMPENSATION. Executive
shall be entitled to receive additional benefits and compensation from the
Company in such form and to such extent as specified below:

            (i) Payment of all premiums for coverage for Executive and his
      dependent family members under health, hospitalization, disability,
      dental, life and other insurance plans that

                                     -2-
<PAGE>
      the Company may have in effect from time to time (all in an amount not
      less than such benefits provided to other Company executives).

            (ii) Reimbursement for all business travel and other out-of-pocket
      expenses and professional dues and fees reasonably incurred by Executive
      in the performance of his services pursuant to this Agreement. All
      reimbursable expenses shall be appropriately documented in reasonable
      detail by Executive upon submission of any request for reimbursement, and
      in a format and manner consistent with the Company's expense reporting
      policy.

            (iii) The Company shall provide Executive with other executive
      perquisites as may be available to or deemed appropriate for Executive by
      the Board and Executive shall be eligible for participation in all other
      Company-wide employee benefits as are available from time to time.

            (iv) The Executive shall be entitled to three weeks paid vacation
      per year.

      3.    NON-COMPETITION AGREEMENT.

      (a) Executive recognizes that the Company's willingness to enter into this
Agreement is based in material part on Executive's agreement to the provisions
of this paragraph 3 and that Executive's breach of the provisions of this
paragraph 3 could materially damage the Company. Subject to and so long as the
Company is not in violation of its obligations under this Agreement, Executive
will not, during the period of his employment by or with the Company, and for a
period of two (2) years immediately following the termination of his employment
under this Agreement, for any reason whatsoever (other than a termination by the
Company without cause, or a termination by Executive with Good Reason (as
hereinafter defined)), directly or indirectly, for himself or on behalf of or in
conjunction with any other person, company, partnership, corporation or business
of whatever nature:

            (i) engage, as an officer, director, shareholder, owner, partner,
      joint venturer, or in a managerial capacity, whether as an employee,
      independent contractor, consultant or advisor, or as a sales
      representative, in any business in direct competition with the Company or
      its subsidiaries, within one hundred (100) miles of where the Company or
      any of its subsidiaries conduct business, including any territory serviced
      by the Company or any of its subsidiaries (the "Territory");

            (ii) call upon any person who is, at that time, within the
      Territory, an employee of the Company or its subsidiaries (including the
      respective subsidiaries thereof) in a managerial capacity for the purpose
      or with the intent of enticing such employee away from or out of the
      employ of the Company or its subsidiaries;

                                     -3-
<PAGE>
            (iii) call upon any person or entity which is, at that time, or
      which has been, within one (1) year prior to that time, a customer of the
      Company or its subsidiaries within the Territory for the purpose of
      soliciting or selling products or services in direct competition with the
      Company or its subsidiaries within the Territory; or

            (iv) call upon any prospective acquisition candidate, on Executive's
      own behalf or on behalf of any competitor, which candidate was, to
      Executive's knowledge after due inquiry, either called upon by the Company
      or its subsidiaries or for which the Company or its subsidiaries made an
      acquisition analysis, for the purpose of acquiring such entity.

      Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit Executive from acquiring as an investment not more than two percent
(2%) of the capital stock of a competing business, whose stock is traded on a
national securities exchange or on an over-the-counter or similar market.

      (b) Because of the difficulty of measuring economic losses to the Company
and its subsidiaries as a result of a breach of the foregoing covenant, and
because of the immediate and irreparable damage that could be caused to the
Company and its subsidiaries for which they would have no other adequate remedy,
Executive agrees that the foregoing covenant may be enforced by the Company or
its subsidiaries, in the event of breach by him, by injunctions and restraining
orders.

      (c) It is agreed by the parties that the foregoing covenants in this
paragraph 3 impose a reasonable restraint on Executive in light of the
activities and business of the Company or its subsidiaries, as the case may be,
on the date of the execution of this Agreement and the current plans of the
Company and its subsidiaries; but it is also the intent of the Company and
Executive that such covenants be construed and enforced in accordance with the
changing activities, business and locations of the Company and its subsidiaries,
as the case may be, throughout the term of this covenant, whether before or
after the date of termination of the employment of Executive. For example, if,
during the term of this Agreement, the Company or its subsidiaries, as the case
may be, engage in new and different activities, enter a new business or
establish new locations for their current activities or business in addition to
or other than the activities or business enumerated under the Recitals above or
the locations currently established therefor, then Executive will be precluded
from soliciting the customers or employees of such new activities or business or
from such new location and from directly competing with such new business within
100 miles of its then- established operating location(s) through the term of
this covenant.

      It is further agreed by the parties hereto that, in the event that
Executive shall cease to be employed hereunder, and shall enter into a business
or pursue other activities not in competition with the Company or its
subsidiaries, or similar activities or business in locations the operation of
which, under such circumstances, does not violate clause (a) of this paragraph
3, and in any event such new business, activities or location are not in
violation of this paragraph 3 or of Executive's obligations

                                     -4-
<PAGE>
under this paragraph 3, if any, Executive shall not be chargeable with a
violation of this paragraph 3 if the Company or its subsidiaries shall
thereafter enter the same, similar or a competitive (i) business, (ii) course of
activities or (iii) location, as applicable.

      (d) The covenants in this paragraph 3 are severable and separate, and the
unenforceability of any specific covenant shall not affect the provisions of any
other covenant. Moreover, in the event any court of competent jurisdiction shall
determine that the scope, time or territorial restrictions set forth are
unreasonable, then it is the intention of the parties that such restrictions be
enforced to the fullest extent which the court deems reasonable, and the
Agreement shall thereby be reformed.

      (e) All of the covenants in this paragraph 3 shall be construed as an
agreement independent of any other provision in this Agreement, and the
existence of any claim or cause of action of Executive against the Company or
its subsidiaries, whether predicated on this Agreement or otherwise, shall not
constitute a defense to the enforcement by the Company or its subsidiaries of
such covenants. It is specifically agreed that the period of two (2) years
following termination of employment stated at the beginning of this paragraph 3,
during which the agreements and covenants of Executive made in this paragraph 3
shall be effective, shall be computed by excluding from such computation any
time during which Executive is in violation of any provision of this paragraph
3.

      4. TERM; TERMINATION; RIGHTS ON TERMINATION. (a) The term of this
Agreement shall begin on the consummation of the IPO and continue for three (3)
years (the "Term"), and, unless terminated sooner as herein provided, shall
continue thereafter on a year-to-year basis on the same terms and conditions
contained herein in effect as of the time of renewal. This Agreement and
Executive's employment may be terminated in any one of the followings ways:

      (i) DEATH. The death of Executive shall immediately terminate this
Agreement with no severance compensation due to Executive's estate.

      (ii) DISABILITY. If, as a result of incapacity due to physical or mental
illness or injury, Executive shall have been absent from his full-time duties
hereunder for four (4) consecutive months, then thirty (30) days after receiving
written notice (which notice may occur before or after the end of such four (4)
month period, but which shall not be effective earlier than the last day of such
four (4) month period), the Company may terminate Executive's employment
hereunder, provided that Executive is unable to resume his full-time duties at
the conclusion of such notice period. Also, Executive may terminate his
employment hereunder if his health should become impaired to an extent that
makes the continued performance of his duties hereunder hazardous to his
physical or mental health or his life, provided that Executive shall have
furnished the Company with a written statement from a qualified doctor to such
effect and provided, further, that, at the Company's request made within thirty
(30) days of the date of such written statement, Executive shall submit to an
examination by a doctor selected by the Company who is reasonably acceptable

                                     -5-
<PAGE>
to Executive or Executive's doctor and such doctor shall have concurred in the
conclusion of Executive's doctor. In the event this Agreement is terminated as a
result of Executive's disability, Executive shall receive from the Company, in a
lump-sum payment due within ten (10) days of the effective date of termination,
the base salary at the rate then in effect for whatever time period is remaining
under the Initial Term (as hereinafter defined) of this Agreement, provided that
such period shall not exceed one (1) year.

      (iii) GOOD CAUSE. The Company may terminate the Agreement ten (10) days
after written notice to Executive for good cause, which shall be: (i)
Executive's breach of any material provision of this Agreement (continuing for
ten (10) days after receipt of notice of need to cure); (ii) Executive's gross
negligence in the performance or intentional nonperformance (continuing for ten
(10) days after receipt of written notice of need to cure) of any of Executive's
material duties and responsibilities hereunder which is harmful or injurious to
the Company; (iii) Executive's dishonesty, fraud or misconduct with respect to
the business or affairs of the Company or its subsidiaries which materially and
adversely affects the operations or reputation of the Company or its
subsidiaries; (iv) Executive's conviction of a felony crime; or (v) alcohol
abuse or a confirmed positive illegal drug test result. In the event of a
termination for good cause, as enumerated above, Executive shall have no right
to any severance compensation but shall receive all compensation due and payable
through the date of termination.

      (iv) WITHOUT CAUSE. At any time after the commencement of employment,
Executive may, without cause, and without Good Reason terminate this Agreement
and Executive's employment, effective thirty (30) days after written notice is
provided to the Company. Executive may only be terminated without cause by the
Company during the Term hereof if such termination is approved by at least
eighty percent (80%) of the members of the Board of Directors of the Company.
Should Executive be terminated by the Company without cause or should Executive
terminate with Good Reason during the first three (3) years of the Term (the
"Initial Term"), Executive shall receive from the Company, in a lump-sum payment
due on the effective date of termination, the base salary at the rate then in
effect for whatever time period is remaining under the Initial Term of this
Agreement or for two (2) years, whichever amount is greater. Should Executive be
terminated by the Company without cause or should Executive terminate with Good
Reason after the Initial Term, Executive shall receive from the Company, in a
lump-sum payment due on the effective date of termination, the base salary at
the rate then in effect equivalent to one (1) year of salary. Further, any
termination without cause by the Company shall operate to shorten the period set
forth in paragraph 3(a) and during which the terms of paragraph 3 apply to one
(1) year from the date of termination of employment. If Executive resigns or
otherwise terminates his employment without cause, rather than the Company
terminating his employment pursuant to this paragraph 4(a)(iv), or if Executive
terminates without Good Reason, Executive shall receive no severance
compensation.

                                     -6-
<PAGE>
      Executive shall have "Good Reason" to terminate this Agreement and his
employment hereunder upon the occurrence of any of the following events: (a)
Executive experiences a reduction in authority, responsibilities or duties to a
position of less stature or importance within the Company than the position
described in paragraph 1 hereof (b) a material breach of this Agreement by the
Company which continues for thirty (30) days after receipt of written notice of
breach is received by the Company from the Employee or (c) Executive is required
to support (by action or silence) conduct which constitutes dishonesty, fraud or
willful misconduct with respect to the business or affairs of the Company or its
subsidiaries.

      Upon termination of this Agreement for any reason provided above,
Executive shall be entitled to receive all compensation earned and/or accrued
and all benefits and reimbursements due and/or accrued through the effective
date of termination. Additional compensation subsequent to termination, if any,
will be due and payable to Executive only to the extent and in the manner
expressly provided above or in paragraph 11. All other rights and obligations of
the Company and Executive under this Agreement shall cease as of the effective
date of termination, except that the Executive's obligations under paragraphs 3,
5, 6, 7, 8 and 9 herein and the Company's obligations with respect to stock
grants, stock options, and severance shall survive such termination in
accordance with their terms.

portion of any awards of stock options or stock grants pursuant to this

            (i) If Executive's employment is terminated by the Company for cause
      or if Executive resigns or terminates his employment other than for Good
      Reason, then any unvested portion of any awards of stock options or stock
      grants shall lapse or shall be forfeited.

            (ii) If Executive's employment is terminated by the Company without
      cause or if Executive terminates his employment for Good Reason, then any
      unvested portion of any awards of stock options or stock grants shall
      immediately vest to their fullest extent (notwithstanding any vesting
      provisions to the contrary) and Executive shall be entitled to all rights
      and privileges associated with such awards (subject to applicable
      securities laws and regulations).

                                     -7-
<PAGE>

plans, financial statements, manuals, memoranda, lists and other property
delivered to or compiled by Executive by or on behalf of the Company, its
subsidiaries or their representatives, vendors or customers which pertain to the
business of the Company or its subsidiaries shall be and remain the property of
the Company or its subsidiaries, as the case may be, and be subject at all times
to their discretion and control. Likewise, all correspondence, reports, records,

activities or future plans of the Company or its subsidiaries which is collected
by Executive shall be delivered promptly to the Company without request by it
upon termination of Executive's employment.

      6. INVENTIONS. Executive shall disclose promptly to the Company any and
all significant conceptions and ideas for inventions, improvements and valuable
discoveries, whether patentable or not, which are conceived or made by
Executive, solely or jointly with another, during the period of employment, and
which are directly related to the business or activities of the Company and
which Executive conceives as a result of his employment by the Company.
Executive hereby assigns and agrees to assign all his interests therein to the
Company or its nominee. Whenever requested to do so by the Company, Executive
shall execute any and all applications, assignments or other instruments that
the Company shall deem necessary to apply for and obtain Letters Patent of the
United States or any foreign country or to otherwise protect the Company's
interest therein.

      7. TRADE SECRETS. Executive agrees that he will not, during or after the
Term of this Agreement with the Company, disclose the specific terms of the
Company's or its subsidiaries' relationships or agreements with their respective
significant vendors or customers or any other significant and material trade
secret of the Company or its subsidiaries, whether in existence or proposed, to
any person, firm, partnership, corporation or business for any reason or purpose

      8.    CONFIDENTIALITY.

unique asset of the Company that gives the Company an advantage over its actual
and potential, current and future competitors. Executive further acknowledges
and agrees that Executive owes the Company a fiduciary duty to

                                     -8-
<PAGE>
preserve and protect all Confidential Information from unauthorized disclosure
or unauthorized use, that certain Confidential Information constitutes "trade
secrets" under applicable laws, and that unauthorized disclosure or unauthorized
use of the Company's Confidential Information would irreparably injure the
Company.

      (b) Both during the term of Executive's employment and after the
termination of Executive's employment for any reason (including wrongful
termination), Executive shall hold all Confidential Information in strict
confidence, and shall not use any Confidential Information except for the
benefit of the Company, in accordance with the duties assigned to Executive.
Executive shall not, at any time (either during or after the term of Executive's
employment), disclose any Confidential Information to any person or entity
(except other employees of the Company who have a need to know the information
in connection with the performance of their employment duties), or copy,
reproduce, modify, decompile or reverse engineer any Confidential Information,
or remove any Confidential Information from the Company's premises, without the
prior consent of the CEO of the Company or the Board of Directors of the Company
or permit any other person to do so. In the event Executive is requested or
required (by oral questions, interrogatories, requests for information or
documents, subpoena, civil investigative demand or other process) to disclose
any Confidential Information, Executive will provide the Company with immediate
written notice of any such request or requirement so that the Company may seek
an appropriate protective order and/or seek with Executive's cooperation to
narrow the request or demand or waive Executive's compliance with the provisions
of this Agreement. If, failing the entry of a protective order or the receipt of
a waiver hereunder, Executive is, in the opinion of his counsel, compelled to
disclose Confidential Information, Executive may disclose only that portion of
the Confidential Information which Executive's counsel advises Executive in
writing that Executive is compelled to disclose and Executive will exercise his
or her best efforts to obtain assurance that confidential treatment will be
accorded such Confidential Information. In any event, Executive will not oppose
action by the Company to obtain an appropriate protective order or other
reliable assurance that confidential treatment will be accorded the Confidential
Information. Executive shall take reasonable precautions to protect the physical
security of all documents and other material containing Confidential Information
(regardless of the medium on which the Confidential Information is stored). This
Agreement applies to all Confidential Information, whether now known or later to
become known to Executive.

      (c) Upon the termination of Executive's employment with the Company for
any reason, and upon request of the Company at any other time, Executive shall
promptly surrender and deliver to the Company all documents and other written
material of any nature containing or pertaining to any Confidential Information
and shall not retain any such document or other material. Within five days of
any such request, Executive shall certify to the Company in writing that all
such materials have been returned.

                                     -9-
<PAGE>
      (d) As used in this Agreement, the term "Confidential Information" shall
mean any information or material known to or used by or for the Company (whether
or not owned or developed by the Company and whether or not developed by
Executive) that is not generally known to the public. Confidential information
includes, but is not limited to, the following: all trade secrets of the
Company; all information that the Company has marked as confidential or has
otherwise described to Executive (either in writing or orally) as confidential;
all nonpublic information concerning the Company's products, services,
prospective products or services, research, product designs, prices, discounts,
costs, marketing plans, marketing techniques, market studies, test data,
customers, customer lists and records, suppliers and contracts; all Company
business records and plans; all Company personnel files; all financial
information of or concerning the Company; all information relating to operating

source codes, object codes, copyrights and other intellectual property; all
technical specifications; any proprietary information belonging to the Company;
all computer hardware or software manual; all training or instruction manuals;
and all data and all computer system passwords and user codes.

      9. NO PRIOR AGREEMENTS. Executive hereby represents and warrants to the
Company that the execution of this Agreement by Executive and his employment by
the Company and the performance of his duties hereunder will not violate or be a
breach of any agreement with a former employer, client or any other person or
entity. Further, Executive agrees to indemnify the Company for any claim,
including, but not limited to, attorneys' fees and expenses of investigation, by
any such third party that such third party may now have or may hereafter come to
have against the Company based upon or arising out of any non-competition
agreement, invention or secrecy agreement between Executive and such third party
which was in existence as of the date of this Agreement.

      10. ASSIGNMENT; BINDING EFFECT. Executive understands that he has been
selected for employment by the Company on the basis of his personal
qualifications, experience and skills. Executive agrees, therefore, that he
cannot assign all or any portion of his performance under this Agreement.
Subject to the preceding two (2) sentences and the express provisions of
paragraph 11 below, this Agreement shall be binding upon, inure to the benefit
of and be enforceable by the parties hereto and their respective heirs, legal
representatives, successors and assigns.

      11.   CHANGE IN CONTROL.

      (a) Unless he elects to terminate this Agreement pursuant to subsections
b, c or d below, Executive understands and acknowledges that the Company may be
merged or consolidated with or into another entity and that such entity shall
automatically succeed to the rights and obligations of the Company hereunder or
that the Company may undergo another type of Change in Control. In the event

of the Term or any extension or renewal thereof, then the provisions of this
paragraph 11 shall be applicable.

      (b) In the event of a Change in Control wherein the Company and Executive
have not received written notice at least five (5) business days prior to the
date of the event giving rise to the Change in Control from the successor to all
or a substantial portion of the Company's business and/or assets that such
successor is willing as of the closing to assume and agrees to perform the
Company's obligations under this Agreement in the same manner and to the same
extent that the Company is hereby required to perform, then Executive may, at
Executive's sole discretion, elect to terminate Executive's employment on such
Change in Control by providing written notice to the Company prior to the
closing of the transaction giving rise to the Change in Control. In such case,
the applicable provisions of paragraph 4(a)(iv) will apply as though the Company
had terminated Executive without cause during the Initial Term; however, the
amount of the lump sum severance payment due Executive pursuant to this
paragraph 11(b) shall be triple the amount calculated under the terms of
paragraph 4(a)(iv), but shall in no event exceed four times Executive's base
salary.

      (c) In any Change in Control situation, Executive may, at Executive's sole
discretion, elect to terminate Executive's employment upon the effective date of
such Change in Control by providing written notice to the Company at least ten
(10) business days prior to the closing of the transaction (or ten (10) business
days after receipt of notice of such transaction, whichever is later) giving
rise to the Change in Control. In such case, the applicable provisions of
paragraph 4(a)(iv) will apply as though the Company had terminated Executive
without cause during the Initial Term; however, the amount of the lump sum
severance payment due Executive pursuant to this paragraph 11(c) shall be double
the amount calculated under the terms of paragraph 4(a)(iv), but shall in no
event exceed three times Executive's base salary.

      (d) If, on or within one year following the effective date of a Change in
Control the Company terminates Executive's employment other than for cause or if
Executive's employment with the Company is terminated by the Company within
three months before the effective date of a Change in Control other than for
cause and it is reasonably demonstrated that such termination (i) was at the
request of a third party that has taken steps reasonably calculated to effect a
Change in Control, or (ii) otherwise arose in connection with or anticipation of
a Change in Control, then Executive shall receive from Company, in a lump sum
payment due on the effective date of termination, the same amount which
Executive would have received pursuant to a termination under paragraph 11(b)
above.

      (e) Solely for purposes of applying paragraph 4 under the circumstances
described in (b) above, the effective date of termination will be the closing
date of the transaction giving rise to the Change in Control and all
compensation, reimbursements and lump-sum payments due Executive must be paid in
full by the Company at or prior to such closing.

      acquisition such person is, directly or indirectly, the beneficial owner
      of voting securities representing thirty (30%) or more of the total voting
      power of all of the then-outstanding voting securities of the Company;

            (ii) the stockholders of the Company shall approve a merger,
      consolidation, recapitalization or reorganization of the Company, or a
      reverse stock split of outstanding voting securities, or consummation of
      any such transaction if stockholder approval is not obtained, other than
      any such transaction which would result in at least seventy-five (75%) of
      the total voting power represented by the voting securities of the
      surviving entity outstanding immediately after such transaction being
      beneficially owned by at least seventy-five (75%) of the holders of
      outstanding voting securities of the Company immediately prior to the
      transactions with the voting power of each such continuing holder relative
      to other such continuing holders not substantially altered in the
      transaction; or

            (iii) the stockholders of the Company shall approve a plan of
      complete liquidation of the Company or an agreement for the sale or
      disposition by the Company of all or a substantial portion of the

      Company).

Company on the date of the Change of Control.

any awards of stock options or stock grants pursuant to this Agreement or
otherwise shall immediately vest and become exercisable to their fullest extent

entitled to all rights and privileges associated with such awards (subject to

      SECTION 4.  SHARES AVAILABLE FOR AWARDS.

      (a) SHARES AVAILABLE. Subject to adjustment as provided in Section 4(c),
the number of Shares with respect to which Awards may be granted under the Plan
shall be 1,700,000. If any Award is forfeited or otherwise terminates or is

unissued Shares or of treasury Shares.

securities, or other property), recapitalization, stock split, reverse stock
split, reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, or exchange of Shares or other securities of the Company, issuance
of warrants or other rights to purchase Shares or other securities of the
Company, or other similar corporate transaction or event affects the Shares such
that an adjustment is determined by the Committee to be appropriate in order to
prevent dilution or enlargement of the benefits or potential benefits intended
to be made available under the Plan, then the Committee shall, in such manner as
it may deem equitable, adjust any or all of (i) the number and type of Shares
(or other securities or property) with respect to which Awards may be granted,
(ii) the number and type of Shares (or other securities or property) subject to
outstanding Awards, and (iii) the grant or exercise price with respect to any
Award or, if deemed appropriate, make provision for a cash payment to the holder
of an outstanding Award; provided, in each case, that with respect to Awards of
Incentive Stock Options and Awards intended to qualify as performance based
compensation under Section 162(m)(4)(C) of the Code, no such adjustment shall be
authorized to the extent that such authority would cause the Plan to violate
Section 422(b)(1) of the Code or would cause such Award to fail to so qualify
under Section 162(m) of the Code, as the case may be, or any successor
provisions thereto; and provided, further, that the number of Shares subject to
any Award denominated in Shares shall always be a whole number.

      of grant, but shall be subject to earlier termination as follows: Director
      Options, must be exercised within three months of the date the Participant
      ceases to serve as a member of the Board, unless such termination results
      from the Participant's death or disability, in which case the
      Participant's Director Options may be exercised by the Participant's legal
      representative or the person to whom the Participant's rights shall pass
      by will or the laws of descent and distribution, as the case may be,
      within one year from the date of termination; provided, however, that such
      event shall not extend the normal expiration date of such Director
      Options.

            (vii) AUTOMATIC LIMITS. In the event that the number of Shares
      available for grants under this Plan is insufficient to make all automatic
      grants provided for in paragraphs (i) or (ii) above on the applicable
      date, then all Directors who are entitled to a grant on such date shall
      share ratably in the number of Shares then available for grant under this
      Plan, and shall have no right to receive a grant with respect to the
      deficiencies in the number of available Shares and all future grants under
      this Section 6(b) shall terminate.

      (c) RESTRICTED STOCK. Subject to the provisions of the Plan, the Committee
shall have the authority to determine the Participants (other than Directors) to
whom Restricted Stock shall be granted, the number of Shares of Restricted Stock
to be granted to each such Participant, the duration of the Restricted Period
during which, and the conditions, including the performance criteria, if any,
under which, the Restricted Stock may be forfeited to the Company, and the other
terms and conditions of such Awards.

            (i) DIVIDENDS. Dividends paid on Restricted Stock may be paid
      directly to the Participant, may be subject to risk of forfeiture and/or
      transfer restrictions during any period established by the Committee or
      sequestered and held in a bookkeeping cash account (with or without
      interest) or reinvested on an immediate or deferred basis in additional
      shares of Common Stock, which credit or shares may be subject to the same
      restrictions as the underlying Award or such other restrictions, all as
      determined by the Committee in its discretion.

            (ii) REGISTRATION. Any Restricted Stock may be evidenced in such
      manner as the Committee shall deem appropriate, including, without
      limitation, book-entry registration or

                                       -7-
<PAGE>
      issuance of a stock certificate or certificates. In the event any stock
      certificate is issued in respect of Restricted Stock granted under the
      Plan, such certificate shall be registered in the name of the Participant
      and shall bear an appropriate legend referring to the terms, conditions,
      and restrictions applicable to such Restricted Stock.

            (iii) FORFEITURE AND RESTRICTIONS LAPSE. Except as otherwise
      determined by the Committee or the terms of the Award or other agreement
      that granted the Restricted Stock, upon termination of a Participant's
      employment (as determined under criteria established by the Committee) for
      any reason (other than a Change in Control) during the applicable
      Restricted Period, all Restricted Stock shall be forfeited by the
      Participant and re-acquired by the Company. The Committee may, when it
      finds that a waiver would be in the best interests of the Company and not
      cause such Award, if it is intended to qualify as performance based
      compensation under Section 162(m) of the Code, to fail to so qualify under
      Section 162(m) of the Code, waive in whole or in part any or all remaining
      restrictions with respect to such Participant's Restricted Stock.
      Unrestricted Shares, evidenced in such manner as the Committee shall deem
      appropriate, shall be issued to the holder of Restricted Stock promptly
      after the applicable restrictions have lapsed or otherwise been satisfied.

            (iv) TRANSFER RESTRICTIONS. During the Restricted Period, Restricted
      Stock will be subject to the limitations on transfer as provided in
      Section 6(j)(iii).

            (v) LIMIT. The maximum number of Shares of Restricted Stock that may
      be granted to any Participant during any year shall not exceed 250,000
      Shares.

      (d) PERFORMANCE AWARDS. The Committee shall have the authority to
determine the Participants (other than Directors) who shall receive a
Performance Award, which shall be denominated as a cash amount at the time of
grant and confer on the Participant the right to receive payment of such Award,
in whole or in part, upon the achievement of such performance goals during such
performance periods as the Committee shall establish with respect to the Award.

            (i) TERMS AND CONDITIONS. Subject to the terms of the Plan and any
      applicable Award Agreement, the Committee shall determine the performance
      goals to be achieved during any performance period, the length of any
      performance period, the amount of any Performance Award and the amount of
      any payment or transfer to be made pursuant to any Performance Award.

            (ii) PAYMENT OF PERFORMANCE AWARDS. Performance Awards may be paid
      (in cash and/or in Shares, in the sole discretion of the Committee) in a
      lump sum or in installments following the close of the performance period,
      in accordance with procedures established by the Committee with respect to
      such Award.

            (iii) LIMIT. The maximum number of Performance Awards that may be
      granted to any Participant during any year shall not exceed $2 million.

                                       -8-
<PAGE>
      (e) BONUS SHARES. The Committee shall have the authority, in its
discretion, to grant Bonus Shares to Participants (other than Directors). Each
Bonus Share shall constitute a transfer of an unrestricted Share to the
Participant, without other payment therefor.

      (f) PHANTOM SHARES. The Committee shall have the authority to grant Awards
of Phantom Shares to Participants (other than Directors) upon such terms and
conditions as the Committee may determine.

            (i) TERMS AND CONDITIONS. Each Phantom Share Award shall constitute
      an agreement by the Company to issue or transfer a specified number of
      Shares or pay an amount of cash equal to a specified number of Shares, or
      a combination thereof to the Participant in the future, subject to the
      fulfillment during the Restricted Period of such conditions, including
      performance objectives, if any, as the Committee may specify at the date
      of grant. During the Restricted Period, the Participant shall not have any
      right to transfer any rights under the subject Award, shall not have any
      rights of ownership in the Phantom Shares and shall not have any right to
      vote such shares.

            (ii) DIVIDENDS. Any Phantom Share award may provide that any or all
      dividends or other distributions paid on Shares during the Restricted
      Period be credited in a cash bookkeeping account (without interest) or
      that equivalent additional Phantom Shares be awarded, which account or
      shares may be subject to the same restrictions as the underlying Award or
      such other restrictions as the Committee may determine.

            (iii) LIMIT. The maximum number of Phantom Shares that may be
      awarded to any Participant during any year shall not exceed 250,000
      Phantom Shares.

      (g) CASH AWARDS. The Committee shall have the authority to determine the
Participants (other than Directors) to whom Cash Awards shall be granted, the
amount, and the terms or conditions, if any, of such Award. A Cash Award may be
granted (simultaneously or subsequently) separately or in tandem with another
Award and may entitle a Participant to receive a specified amount of cash from
the Company upon such other Award becoming taxable to the Participant, which
cash amount may be based on a formula relating to the anticipated taxable income
associated with such other Award and the payment of the Cash Award.

      (h) OTHER STOCK-BASED AWARDS. The Committee may also grant to Participants
(other than Directors) an Other Stock-Based Award, which shall consist of a
right which is an Award denominated or payable in, valued in whole or in part by
reference to, or otherwise based on or related to, Shares as is deemed by the
Committee to be consistent with the purposes of the Plan. Subject to the terms
of the Plan, the Committee shall determine the terms and conditions of any such
Other Stock-Based Award.

      (i) REPLACEMENT GRANTS. Awards may be granted from time to time in
substitution for similar awards held by employees of other corporations who
become Participants as the result of a

                                       -9-
<PAGE>
merger or consolidation of the employing corporation with the Company or any
subsidiary, or the acquisition by the Company or any subsidiary of the assets of
the employing corporation, or the acquisition by the Company or any subsidiary
or an affiliate of stock of the employing corporation. The terms and conditions
of substitute Awards granted may vary from the terms and conditions set forth in
the Plan, to the extent the Committee, at the time of grant, deems it
appropriate to conform, in whole or in part, to the provisions of awards in
substitution for which they are granted.

      (j)   GENERAL.

            (i) AWARDS MAY BE GRANTED SEPARATELY OR TOGETHER. Awards may, in the
      discretion of the Committee, be granted either alone or in addition to, in
      tandem with, or in substitution for any other Award granted under the Plan
      or any award granted under any other plan of the Company or any Affiliate.
      Awards granted in addition to or in tandem with other Awards or awards
      granted under any other plan of the Company or any Affiliate may be
      granted either at the same time as or at a different time from the grant
      of such other Awards or awards.

            (ii) FORMS OF PAYMENT BY COMPANY UNDER AWARDS. Subject to the terms
      of the Plan and of any applicable Award Agreement, payments or transfers
      to be made by the Company or an Affiliate upon the grant, exercise or
      payment of an Award may be made in such form or forms as the Committee
      shall determine, including, without limitation, cash, Shares, other
      securities, other Awards or other property, or any combination thereof,
      and may be made in a single payment or transfer, in installments, or on a
      deferred basis, in each case in accordance with rules and procedures
      established by the Committee. Such rules and procedures may include,
      without limitation, provisions for the payment or crediting of reasonable
      interest on installment or deferred payments.

            (iii) LIMITS ON TRANSFER OF AWARDS.

                  (A) Except as provided in (C) below, each Award, and each
            right under any Award, shall be exercisable only by the Participant
            during the Participant's lifetime, or, if permissible under
            applicable law, by the Participant's guardian or legal
            representative as determined by the Committee.

                  (B) Except as provided in (C) below, no Award and no right
            under any such Award may be assigned, alienated, pledged, attached,
            sold or otherwise transferred or encumbered by a Participant
            otherwise than by will or by the laws of descent and distribution
            (or, in the case of Restricted Stock, to the Company) and any such
            purported assignment, alienation, pledge, attachment, sale, transfer
            or encumbrance shall be void and unenforceable against the Company
            or any Affiliate.

                  (C) Notwithstanding anything in the Plan to the contrary, to
            the extent specifically provided by the Committee with respect to a
            grant, a Nonqualified Stock

                                      -10-
<PAGE>
            Option may be transferred to immediate family members or related
            family trusts, limited partnerships or similar entities or Persons
            or on such terms and conditions as the Committee may establish.

            (iv) TERM OF AWARDS. The term of each Award shall be for such period
      as may be determined by the Committee; provided, that in no event shall
      the term of any Award exceed a period of 10 years from the date of its
      grant.

            (v) SHARE CERTIFICATES. All certificates for Shares or other
      securities of the Company or any Affiliate delivered under the Plan
      pursuant to any Award or the exercise thereof shall be subject to such
      stop transfer orders and other restrictions as the Committee may deem
      advisable under the Plan or the rules, regulations, and other requirements
      of the SEC, any stock exchange upon which such Shares or other securities
      are then listed, and any applicable Federal or state laws, and the
      Committee may cause a legend or legends to be put on any such certificates
      to make appropriate reference to such restrictions.

            (vi) CONSIDERATION FOR GRANTS. Awards may be granted for no cash
      consideration or for such consideration as the Committee determines
      including, without limitation, such minimal cash consideration as may be
      required by applicable law.

            (vii) DELIVERY OF SHARES OR OTHER SECURITIES AND PAYMENT BY
      PARTICIPANT OF CONSIDERATION. No Shares or other securities shall be
      delivered pursuant to any Award until payment in full of any amount
      required to be paid pursuant to the Plan or the applicable Award Agreement
      (including, without limitation, any exercise price, tax payment or tax
      withholding) is received by the Company. Such payment may be made by such
      method or methods and in such form or forms as the Committee shall
      determine, including, without limitation, cash, Shares, other securities,
      other Awards or other property, withholding of Shares, cashless exercise
      with simultaneous sale, or any combination thereof; provided that the
      combined value, as determined by the Committee, of all cash and cash
      equivalents and the Fair Market Value of any such Shares or other property
      so tendered to the Company, as of the date of such tender, is at least
      equal to the full amount required to be paid pursuant to the Plan or the
      applicable Award Agreement to the Company.

            (viii)PERFORMANCE CRITERIA. The Committee shall establish
      performance goals applicable to those Awards (other than Options) the
      payment of which is intended by the Committee to qualify as
      "performance-based compensation" as described in Section 162(m)(4)(C) of
      the Code. The performance goals shall be based upon the attainment of such
      target levels of net income, cash flows, return on equity, profit margin
      or sales, stock price, return on assets, economic value added, and/or
      earnings per share as may be specified by the Committee. Which factor or
      factors to be used with respect to any grant, and the weight to be
      accorded thereto if more than one factor is used, shall be determined by
      the Committee at the time of grant.

                                      -11-

      SECTION 7.   AMENDMENT AND TERMINATION.

      Except to the extent prohibited by applicable law and unless otherwise
expressly provided in an Award Agreement or in the Plan:

            (i) AMENDMENTS TO THE PLAN. The Board or the Committee may amend,
      alter, suspend, discontinue, or terminate the Plan without the consent of
      any stockholder, Participant, other holder or beneficiary of an Award, or
      other Person; provided, however, notwithstanding any other provision of
      the Plan or any Award Agreement, without the approval of the stockholders
      of the Company no such amendment, alteration, suspension, discontinuation,
      or termination shall be made that would increase the total number of
      Shares available for Awards under the Plan, except as provided in Section
      4(c) of the Plan.

            (ii) AMENDMENTS TO AWARDS. The Committee may waive any conditions or
      rights under, amend any terms of, or alter any Award theretofore granted,
      provided no change in any Award shall reduce the benefit to Participant
      without the consent of such Participant. Notwithstanding the foregoing,
      with respect to any Award intended to qualify as performance-based
      compensation under Section 162(m) of the Code, no adjustment shall be
      authorized to the extent such adjustment would cause the Award to fail to
      so qualify.

      SECTION 8.   CHANGE IN CONTROL.

      Notwithstanding any other provision of this Plan to the contrary, in the
event of a Change in Control of the Company all outstanding Awards automatically
shall become fully vested immediately prior to such Change in Control (or such
earlier time as set by the Committee), all restrictions, if any, with respect to
such Awards shall lapse, including, without limitation, any service, longevity
or year-end employment requirements, all performance criteria, if any, with
respect to such Awards shall be deemed to have been met in full and all
Performance Awards and Cash Awards shall be payable to the maximum extent 
possible without regard to Pro-ration.

      SECTION 9.   GENERAL PROVISIONS.

      (a) NO RIGHTS TO AWARDS. Except as provided in Section 6(b), no
Participant or other Person shall have any claim to be granted any Award, there
is no obligation for uniformity of treatment of Participants, or holders or
beneficiaries of Awards and the terms and conditions of Awards need not be the
same with respect to each recipient.

      (b) WITHHOLDING. The Company or any Affiliate is authorized to withhold
from any Award, from any payment due or transfer made under any Award or under
the Plan or from any compensation or other amount owing to a Participant the
amount (in cash, Shares, other securities, Shares that would otherwise be issued
pursuant to such Award, other Awards or other property) of any applicable taxes
payable in respect of an Award, its exercise, the lapse of restrictions thereon,
or any payment or transfer under an Award or under the Plan and to take such
other action as may be necessary in the opinion of the Company to satisfy all
obligations for the payment of such taxes.

                                      -12-
<PAGE>
In addition, the Committee may provide, in an Award Agreement, that the
Participant may direct the Company to satisfy such Participant's tax obligation
through the withholding of Shares otherwise to be acquired upon the exercise or
payment of such Award.

      (c) NO RIGHT TO EMPLOYMENT. The grant of an Award shall not be construed
as giving a Participant the right to be retained in the employ of the Company or
any Affiliate. Further, the Company or an Affiliate may at any time dismiss a
Participant from employment, free from any liability or any claim under the
Plan, unless otherwise expressly provided in the Plan or in any Award Agreement.

      (d) GOVERNING LAW. The validity, construction, and effect of the Plan and
any rules and regulations relating to the Plan shall be determined in accordance
with the laws of the State of Delaware and applicable federal law.

      (e) SEVERABILITY. If any provision of the Plan or any Award is or becomes
or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as
to any Person or Award, or would disqualify the Plan or any Award under any law
deemed applicable by the Committee, such provision shall be construed or deemed
amended to conform to the applicable laws, or if it cannot be construed or
deemed amended without , in the determination of the Committee, materially
altering the intent of the Plan or the Award, such provision shall be stricken
as to such jurisdiction, Person or Award and the remainder of the Plan and any
such Award shall remain in full force and effect.

      (f) OTHER LAWS. The Committee may refuse to issue or transfer any Shares
or other consideration under an Award if, acting in its sole discretion, it
determines that the issuance of transfer or such Shares or such other
consideration might violate any applicable law or regulation or entitle the
Company to recover the same under Section 16(b) of the Exchange Act, and any
payment tendered to the Company by a Participant, other holder or beneficiary in
connection with the exercise of such Award shall be promptly refunded to the
relevant Participant, holder or beneficiary.

      (g) NO TRUST OR FUND CREATED. Neither the Plan nor the Award shall create
or be construed to create a trust or separate fund of any kind or a fiduciary
relationship between the Company or any Affiliate and a Participant or any other
Person. To the extent that any Person acquires a right to receive payments from
the Company or any Affiliate pursuant to an Award, such right shall be no
greater than the right of any general unsecured creditor of the Company or any
Affiliate.

      (h) NO FRACTIONAL SHARES. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash, other securities, or other property shall be paid or transferred
in lieu of any fractional Shares or whether such fractional Shares or any rights
thereto shall be canceled, terminated, or otherwise eliminated.

                                     -13-
<PAGE>
      (i) HEADINGS. Headings are given to the Sections and subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.

      (j) PARACHUTE TAX GROSS-UP. To the extent that the grant, payment, or
acceleration of vesting or payment, whether in cash or stock, of any Award made
to a Participant under the Plan (a "Benefit") is subject to an excise tax under
Section 4999(a) of the Code (a "Parachute Tax"), the Company shall pay such
person an amount of cash (the "Gross-up Amount") such that the "net" Benefit
received by the person under this Plan, after paying all applicable Parachute
Taxes (including those on the Gross-up Amount) and any taxes on the Gross-up
Amount, shall be equal to the Benefit that such person would have received if
such Parachute Tax had not been applicable.

      SECTION 10.   EFFECTIVE DATE OF THE PLAN.

      The Plan shall be effective as of the date of its approval by the Board.

      SECTION 11.   TERM OF THE PLAN.

      No Award shall be granted under the Plan after the 10th anniversary of the
effective date of the Plan. However, unless otherwise expressly provided in the
Plan or in an applicable Award Agreement, any Award granted prior to such
termination, and the authority of the Board or the Committee to amend, alter,
adjust, suspend, discontinue, or terminate any such Award or to waive any
conditions or rights under such Award, shall extend beyond such termination
date.
