THE EXCHANGE OFFER

     On May 19, 1999, we completed a private offering of 11 5/8% Senior
Subordinated Notes due 2008. The notes were sold for a total purchase price of
$122,417,500.

     We entered into a registration rights agreement with the initial purchasers
in the private offering in which we agreed to deliver to you this prospectus and
to use our best efforts to complete the exchange offer by November 15, 1999.
This exchange offer entitles you to exchange your notes for notes with identical
terms that are registered with the SEC. If the exchange offer is not completed
by November 15, 1999, the interest rate on the notes will be increased by 0.25%
per year for each 90-day period during which the exchange offer is not
completed. The maximum amount by which the interest rate will be increased is
0.5% in total. After the exchange offer is complete, you will no longer be
entitled to any exchange or registration rights for your notes. You should read
the discussion under the heading "The Exchange Offer" beginning on page   and
"Description of the Notes" beginning on page   for further information about the
exchange notes.

The Exchange Offer.........  We are offering to exchange up to $125,000,000 of
                             the exchange notes for up to $125,000,000 of the
                             existing notes. Existing notes may be exchanged
                             only in $1,000 increments.

                             The terms of the exchange notes are identical in
                             all material respects to the existing notes except
                             the exchange notes will not be subject to transfer
                             restrictions and holders of exchange notes will
                             have no registration rights. Also, the exchange
                             notes will not contain provisions for an increase
                             in their stated interest rate.

Resale.....................  We believe the notes issued in the exchange offer
                             may be offered for resale, resold and otherwise
                             transferred by you without compliance with the
                             registration and prospectus delivery provisions of
                             the Securities Act provided that:

                             - the notes received in the exchange offer are
                               acquired in the ordinary course of your business;

                             - you are not participating and have no
                               understanding with any person to participate in
                               the distribution of the notes issued to you in
                               the exchange offer; and

                             - you are not an affiliate of ours.

accordingly, will not bear legends restricting their transfer. Also, the
exchange notes will not contain the penalty interest provisions related to the

notes, and both the existing notes and the exchange notes are governed by the
same indenture.

Issuer..................... American Plumbing & Mechanical, Inc.
                             1502 Augusta, Suite 425
                             Houston, Texas 77057
                             (713) 243-7350

Total Amount...............  $125,000,000 total principal amount of 11 5/8%
                             Senior Subordinated Notes due 2008.

Maturity...................  October 15, 2008.

Interest Payment Dates.....  April 15 and October 15, beginning October 15,
                             1999.

Guarantees.................  Each of our direct subsidiaries will jointly and
                             severally guarantee the exchange notes. Future
                             subsidiaries also may be required to guarantee the
                             exchange notes. The guarantees are full and
                             unconditional. If we cannot make payments on the
                             notes when they are due, our guarantor subsidiaries
                             must make them. See "Description of the
                             Notes -- The Guarantees."

Ranking....................  The exchange notes and the subsidiary guarantees
                             are referred to as senior subordinated debt because
                             they are, by their terms, ranked behind our
                             existing and future senior indebtedness and ranked
                             ahead of our existing and future subordinated
                             indebtedness in right of payment. Because the
                             exchange notes are subordinated, in the event of
                             bankruptcy, liquidation or dissolution, holders of
                             the exchange notes will not receive any payment
                             until holders of senior indebtedness and guarantor
                             senior indebtedness have been paid in full. The
                             exchange notes and the subsidiary guarantees:

                             - rank equally with our other senior subordinated
                               debt;

                             - rank ahead of all of our subordinated debt; and

                             - rank below our senior indebtedness.

                             The terms "senior indebtedness" and "guarantor
                             senior indebtedness" are defined in the

                             section of this prospectus.

                             As of March 31, 1999, we had $3.1 million of
                             consolidated senior indebtedness outstanding.

Optional Redemption........  We may redeem some or all of the exchange notes at
                             any time on or after April 15, 2004 at the
                             redemption prices listed under the heading
                             "Description of the Notes -- Optional Redemption."

Optional Redemption

  Equity...................  Before April 15, 2002, we may redeem up to 35% of
                             the total principal amount of the exchange notes
                             with the net proceeds of sales of equity in AMPAM
                             at the price listed in the section "Description of

                             at least 65% of the total principal amount of the
                             exchange notes originally issued remains
                             outstanding after the redemption.

Change of Control..........  If we sell assets or if a change of control occurs,
                             we may be required to offer to repurchase the
                             exchange notes at the prices listed in the section
                             "Description of the Notes," under the heading
                             "Change of Control."

Basic Covenants of the
Indenture..................  The indenture governing the exchange notes contains
                             covenants that, among other things, restrict our
                             ability and the ability of our restricted
                             subsidiaries to:

                             - borrow money;

                             - pay dividends on stock or purchase stock;

                             - make investments;

                             - use our assets as security in other transactions;

                             - sell material assets or merge with or into other
                               companies;

                             - sell stock in our subsidiaries; and

                             - restrict the ability of our subsidiaries to pay
                               dividends and make other payments.

                             These covenants are subject to important exceptions
                             and qualifications, which are described in the
                             section "Description of the Notes" under the
                             heading "Material Covenants" in this prospectus.

Risk Factors...............  See "Risk Factors" for a discussion of factors you
                             should carefully consider before deciding to invest
                             in the notes.

OUR COMPANY

     We believe we are the largest company in the United States focused
primarily on the plumbing and mechanical contracting services industry. On April
1, 1999, we combined the operations of the ten founding companies, which
individually are leading regional providers of plumbing and mechanical
contracting services, and commenced operations as one company. We believe that
by combining these regional leaders into one professional organization, we have
created a national provider which we expect to strengthen and broaden our
relationships with our consolidating customer base and enhance our operating
efficiency. The ten founding companies have been in business for an average of
approximately 31 years and, in 1998, performed plumbing and mechanical
contracting services in 24 states. On a pro forma basis for the fiscal year
ended December 31, 1998, we generated revenues and EBITDA of $322.2 million and
$39.6 million, respectively.

     Almost all construction and renovation in the United States creates demand
for plumbing and mechanical contracting services. Depending upon the exact scope
of the work, we estimate that the plumbing and mechanical contracting services
work we perform generally accounts for approximately 8% to 12% of the total
construction cost of a commercial and institutional project and approximately 5%
to 10% of the total construction cost of a residential project. In 1992, the
most recent year for which data are available from the United States Department
of Commerce, the value of new construction and repair and maintenance work
completed by plumbing and mechanical contractors totaled approximately $28
billion, including approximately $17 billion from plumbing services and $11
billion from mechanical services.

OUR COMPETITIVE STRENGTHS

     We believe several factors give us a competitive advantage in our industry,
including our:

     - strong customer relationships and market leadership;

     - geographically diverse operations;

     - large and highly skilled work force;

     - diverse business mix; and

     - experienced management team.

OUR BUSINESS STRATEGY

     Our goal is to build on our position as a leading provider of plumbing and
mechanical contracting services in the residential and commercial/institutional
markets by:

     - increasing our market share and the profitability of our operations; and

     - pursuing a selective acquisition strategy.

OUR OPERATING STRATEGY

     We intend to leverage the geographical presence and competitive strengths
of our founding and subsequently acquired companies with the objective of
continuing strong internal growth. The key elements of our operating strategy
are:

     - achieve purchasing savings and other economies of scale;

     - continue to attract, develop and retain qualified plumbers and management
       personnel;

     - increase off-site prefabrication of plumbing and mechanical systems and
       components;

     - emphasize "value engineering" and design-and-build capability;

     - increase use of technology;

     - leverage geographic presence to obtain and retain multi-location
       customers; and

     - broaden scope of specialty services.

OUR ACQUISITION STRATEGY

     We believe that the highly fragmented nature of the plumbing and mechanical
contracting services industry offers significant opportunities for us to pursue
our acquisition strategy. Key elements of our acquisition strategy include:

     - increase geographic coverage; and

     - expand our service capabilities.

                   SUMMARY PRO FORMA COMBINED FINANCIAL DATA

     The following summary unaudited pro forma financial data for AMPAM, is
adjusted for


     - the effects of the acquisition of the founding companies;



     - the effects of other pro forma adjustments to our historical financial
       statements; and



     - the original issuance of the notes and our use of the proceeds from that
       sale.



     For financial reporting purposes, Christianson is considered to be the
accounting acquiror. This data includes our results of operations as if the
acquisitions and related transactions were closed on January 1 of the respective
period presented. This data does not necessarily indicate the results that we
would have obtained had these events actually occurred on January 1 of the
respective period presented, or our future results. During the periods presented
below, our founding companies were not under common control or management and,
therefore, the data presented may not be comparable to or indicative of future
performance. The unaudited pro forma financial data is based on preliminary
estimates, available information and some assumptions that our management deems
appropriate. Since the information in this table is only a summary and does not
provide all of the information contained in our financial statements, including
the related notes, you should read "-- Selected Individual Founding Company
Financial Data," "Capitalization," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the Financial Statements and
Unaudited Pro Forma Combined Financial Statements and related notes thereto
included elsewhere in this prospectus.

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


(a)  Gives effect to the acquisitions of the founding companies and other
     related pro forma adjustments, as if all of these transactions had occurred
     on January 1 of the respective periods presented and to the portion of the
     proceeds from the private placement of notes to be used to repay existing
     outstanding indebtedness, as if these transactions had occurred on January
     1 of the respective period presented for purposes of the Statement of
     Operations Data and Other Financial Data and Ratios and on March 31, 1999
     for purposes of Balance Sheet Data.



(b)  Reflects an aggregate of approximately $14.7 million and $0.3 million in
     pro forma reductions for the year ended December 31, 1998, and the three
     months ended March 31, 1999, respectively, in salary, bonus and benefits of
     the owners of the founding companies to which they have agreed
     prospectively and the effect of revisions to various lease agreements
     between the founding companies and stockholders of the founding companies.
     Also, for the three months ended March 31, 1999, reflects the reduction of
     other income to eliminate the gain on disposal of assets related to AMPAM's
     acquisition of the founding companies.



     Certain members of management and founders received stock and/or stock
     options in connection with the organization of our company. The applicable
     accounting rules require that the stock issued to some members of our
     management be treated as compensation expense. As a result of this
     treatment, we recorded a non-recurring non-cash charge on April 1, 1999 of
     approximately $7.7 million which will reduce our EBITDA and net income and
     will be reflected in our second quarter results. See "Unaudited Pro Forma
     Combined Financial Statements" and the Notes thereto.


(c)  Reflects amortization of the goodwill 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.


(d)  Reflects the reduction in historical interest expense related to historical
     debt of the founding companies which was transferred to stockholders of the
     founding companies, along with the related nonoperating assets of the
     founding companies, in connection with the acquisitions. Also reflects the
     interest cost on the debt incurred on April 1, 1999 to finance the
     acquisitions.


(e)  Assumes that all pre-tax income before non-deductible goodwill and other
     permanent items is subject to a 39% overall tax rate.


(f)  "EBITDA" means net income before interest expense, taxes, depreciation and
     amortization. EBITDA should not be considered in isolation from or as an
     alternative to net income as an indicator of our operating performance, or
     as an alternative to cash flow from operating activities and other
     consolidated income or cash flow statement data prepared in accordance with
     generally accepted accounting principles or as a measure of profitability
     or liquidity. EBITDA measures presented may not be comparable to other
     similarly titled measures of other companies. We believe EBITDA is a widely
     accepted financial indicator of a company's ability to service debt.



(g)  For the purpose of this calculation "net debt" represents total debt
     (excluding redeemable preferred stock) less cash and cash equivalents.



(h)  For the purpose of this calculation, "earnings" represents income from
     operations before income tax expense, plus fixed charges. "Fixed charges"
     consist of interest, whether expensed or capitalized, amortization of debt
     expense and an estimated portion of rentals representing interest expense.
     Approximately $114.6 million of indebtedness assumed for pro forma purposes
     to be outstanding at March 31, 1999 was retired with a portion of the
     proceeds from the original issuance of notes.



(i)  The redeemable preferred stock has a $0.01 par value per share. Currently,
     there are 1,048,820 shares of Series A Preferred Stock issued and
     outstanding with a liquidation preference of $13.6 million.

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

(a) The fiscal years presented are the years ended December 31, 1996, 1997 and
    1998 for all founding companies, except for Croson Ohio, Sherwood and
    Miller, for which the fiscal years presented are the years ended September
    30, 1996, 1997 and 1998; Nelson, for which the fiscal years presented are
    the years ended April 30, 1997 and December 31, 1997 and 1998; and
    Christianson, for which the fiscal years presented are August 31, 1996 and
    December 31, 1997 and 1998. For the three months ended December 31, 1998,
    Croson Ohio, Sherwood, and Miller had combined revenues of $16,329 and gross
    profit of $3,341.

(b) With respect to some of the founding companies, the statement of operations
    data for the 1996 fiscal year was derived from internal company financial
    records that have not been audited by any independent accountants.
    Accordingly, you are cautioned not to place undue reliance on this
    information. Nevertheless, management believes that the financial
    information shown in this table may be helpful in understanding the past
    operations of the founding companies.

                                  RISK FACTORS

     You should carefully consider the following factors as well as the other
information contained in this registration statement before deciding to invest
in the notes.

- -- WE RECENTLY ACQUIRED THE FOUNDING COMPANIES AND CONDUCTED NO BUSINESS UNTIL
   APRIL 1, 1999. IF TOO MUCH OF MANAGEMENT'S TIME IS SPENT ATTENDING TO
   INTEGRATING THE OPERATIONS, OUR OPERATIONS COULD SUFFER.

     Our company was founded in June 1998 but we had not conducted any
operations or generated any revenues until April 1, 1999 when we acquired the
founding companies. As a result, we have no combined historical financial
results as one company for investors to evaluate. The unaudited pro forma
combined financial results of the founding companies cover periods during which
the founding companies and AMPAM were not under common control or management
and, therefore, may not accurately depict our future financial or operating
results. In addition, historical financial results for the individual founding
companies do not necessarily indicate the future results of our combined
company.

- -- AS A RESULT OF OUR AGGRESSIVE ACQUISITION PROGRAM, WE HAVE GENERATED WHAT WE
   BELIEVE IS A SUBSTANTIAL AMOUNT OF DEBT. OUR CURRENT DEBT LEVEL COULD LIMIT
   OUR ABILITY TO FUND FUTURE WORKING CAPITAL NEEDS AND INCREASE OUR EXPOSURE
   DURING ADVERSE ECONOMIC CONDITIONS. ADDITIONALLY, OUR DEBT LEVEL COULD
   PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER THE NOTES.

     We have now and, after the offering, will continue to have a significant
amount of debt. The following chart, with dollar amounts in thousands, shows
some important credit statistics and is presented assuming we had completed the
original issuance of the notes and applied the proceeds from such sale as of
March 31, 1999:

<TABLE>
<S>                                                           <C>
Total indebtedness..........................................  $125,486
Redeemable preferred stock..................................  $ 13,635
Stockholders' equity........................................  $ 17,683
Ratio of earnings to fixed charges..........................       2.7x
</TABLE>

     Our substantial indebtedness could have important consequences to you. For
example, it could:

     - make it more difficult for us to satisfy our obligations with respect to
       the notes;
     - increase our vulnerability to general adverse economic and industry
       conditions;
     - limit our ability to fund future working capital, capital expenditures
       and other general corporate requirements;
     - limit our flexibility in planning for, or reacting to, changes in our
       business and the industry in which we operate;
     - place us at a disadvantage compared to our competitors that have less
       debt; and
     - limit, along with the financial and other restrictive covenants in our
       indebtedness, among other things, our ability to borrow additional funds.
       Additionally, failing to comply with those covenants could result in an
       event of default which, if not cured or waived, could have a material
       adverse effect on us.

     See "Description of the Notes -- Optional Redemption" and "-- Change of
Control" and "Description of Other Indebtedness."

- -- YOUR RIGHT TO RECEIVE PAYMENTS ON THESE NOTES IS JUNIOR TO OUR EXISTING
   INDEBTEDNESS AND POSSIBLY ALL OF OUR FUTURE BORROWINGS. FURTHER, THE
   GUARANTEES OF THESE NOTES ARE JUNIOR TO ALL OUR GUARANTORS' EXISTING
   INDEBTEDNESS AND POSSIBLY TO ALL THEIR FUTURE BORROWINGS.

     The notes and the subsidiary guarantees rank behind all of our and our
subsidiary guarantors' existing indebtedness and all of our and their future
borrowings, except any future indebtedness that expressly provides that it ranks
equal with, or subordinated in right of payment to, the notes and the
guarantees. As
                                       11
<PAGE>   18

a result, upon any distribution to our creditors or the creditors of the
guarantors in a bankruptcy, liquidation or reorganization or similar proceeding
relating to us or the guarantors or our or their property, the holders of senior
indebtedness of our company and the subsidiary guarantors will be entitled to be
paid in full in cash before any payment may be made with respect to the notes or
the subsidiary guarantees.

     In addition, all payments on the notes and the subsidiary guarantees will
be blocked in the event of a payment default on senior indebtedness and may be
blocked for up to 179 consecutive days in the event of non-payment defaults on
senior indebtedness.

     In the event of a bankruptcy, liquidation or reorganization or similar
proceeding relating to our company or the guarantors, holders of the notes will
participate with trade creditors and all other holders of subordinated
indebtedness of our company and the guarantors in the assets remaining after we
and the subsidiary guarantors have paid all of the senior indebtedness. However,
because the indenture requires that amounts otherwise payable to holders of the
notes in a bankruptcy or similar proceeding be paid to holders of senior
indebtedness instead, holders of the notes may receive less, ratably, than
holders of trade payables in any proceeding of this type. In any of these cases,
we and the subsidiary guarantors may not have sufficient funds to pay all of our
creditors and holders of notes may receive less, ratably, than the holders of
senior indebtedness.

     Assuming we completed the original issuance of the notes and applied the
proceeds on March 31, 1999, these notes and the subsidiary guarantees would have
been subordinated to approximately $3.1 million of senior indebtedness and
approximately $95 million would have been available for borrowing as senior
indebtedness under our credit facility. We will be permitted to borrow
substantial additional indebtedness, including senior indebtedness, in the
future under the terms of the indenture.

- -- TO SERVICE OUR INDEBTEDNESS, WE WILL REQUIRE A SIGNIFICANT AMOUNT OF CASH.
   OUR ABILITY TO GENERATE CASH DEPENDS ON MANY FACTORS BEYOND OUR CONTROL.

     Our ability to make payments on and to refinance our indebtedness,
including the exchange notes, and to fund planned capital expenditures will
depend on our ability to generate cash in the future. This, to an extent, is
subject to general economic, financial, competitive, legislative, regulatory and
other factors that are beyond our control.

     We cannot assure you that our business will generate sufficient cash flow
from operations, that currently anticipated cost savings and operating
improvements will be realized on schedule or that future borrowings will be
available to us under our credit facility in an amount sufficient to enable us
to pay our indebtedness, including the exchange notes, or to fund our other
liquidity needs. We may need to refinance all or a portion of our indebtedness,
including the notes, on or before maturity. We cannot assure you that we will be
able to refinance any of our indebtedness, including our credit facility and the
exchange notes, on commercially reasonable terms or at all.

- -- DESPITE CURRENT INDEBTEDNESS LEVELS, WE AND OUR SUBSIDIARIES MAY STILL BE
   ABLE TO INCUR SUBSTANTIALLY MORE DEBT. THIS COULD FURTHER EXACERBATE THE
   RISKS DESCRIBED ABOVE.

     We may be able to incur substantial additional indebtedness in the future.
Although the indenture contains limitations on our ability to incur additional
indebtedness, it does not prohibit us from doing so and any and all additional
indebtedness could be senior indebtedness. In addition, we have a credit
facility that provides for borrowings up to $95 million, all of which would
constitute senior indebtedness. The senior status of this additional debt means
that if we were to dissolve, all senior indebtedness would be repaid in full
before any amount would be paid to the holders of the notes. If new debt is
added to our current debt levels and the current debt levels of our
subsidiaries, the related risks that we and they now face could intensify.

     See "Capitalization," "Selected Historical Financial Data," "Description of
the Notes -- Optional Redemption" and "-- Change of Control" and "Description of
Other Indebtedness."

<PAGE>   19


- -- DOWNTURNS IN CONSTRUCTION COULD ADVERSELY AFFECT OUR BUSINESS BECAUSE A
   SIGNIFICANT PORTION OF OUR BUSINESS IS DEPENDENT ON LEVELS OF NEW
   CONSTRUCTION ACTIVITY.


     Our business primarily involves the installation of plumbing and mechanical
systems in newly constructed and renovated residential, commercial, industrial
and institutional structures. The level of new commercial and institutional
installations is affected by fluctuations in the level of new construction of
commercial and institutional buildings in the markets in which we operate. The
commercial/institutional market is impacted by local economic conditions,
changes in interest rates, changes in governmental and institutional
appropriations for construction and other related factors. The residential
market is similarly affected by changes in general and local economic
conditions, such as the following:

     - employment and income levels;
     - interest rates and other factors affecting the availability and cost of
       financing;
     - tax implications for home buyers;
     - consumer confidence; and
     - housing demand.

     In addition, economic growth in our areas of operations has increased
substantially in the last several years, enabling us to achieve historic levels
of revenue and net income for the 1998 fiscal year. We can provide no assurances
that these levels of growth can be sustained in the future. A material downturn
in our areas of operations would result in a decline in the number of
residential and commercial housing starts, which could negatively affect our
business, financial condition and results of operations.


- -- OUR PRO FORMA FINANCIAL STATEMENTS ASSUME A RATE AT WHICH WE WILL WRITE OFF
   THE SIGNIFICANT GOODWILL ON OUR BALANCE SHEET AND THIS MAY OVERSTATE OUR PRO
   FORMA EARNINGS. THIS AND OTHER ACQUISITION RELATED ACCOUNTING ISSUES COULD
   HAVE A MATERIAL ADVERSE EFFECT ON OUR FUTURE FINANCIAL RESULTS.



     The acquisition of the founding companies has been accounted for using the
purchase method of accounting, and the total purchase price has been allocated
to the assets and liabilities of the companies acquired based upon the fair
values of the assets and liabilities. As a result, we will have significant non-
cash charges for depreciation and amortization expense related to the fixed
assets and "goodwill" that were acquired in the acquisition. Our balance sheet
includes an amount designated as "goodwill" that on a pro forma as adjusted
basis at March 31, 1999 represented 51% of assets and 609% of stockholders'
equity. In addition, we will pay additional consideration in the form of cash
and stock in the event that adjusted net income of the founding companies for
the year ended December 31, 1999 exceeds targeted levels. These payments, if
any, would result in additional "goodwill." Goodwill arises when an acquiror
pays more for a business than the fair value of the tangible and separately
measurable intangible net assets. Generally accepted accounting principles
require that this and all other intangible assets be amortized over the period
benefited. AMPAM's management has determined that the period to be benefitted by
the amounts designated as goodwill is 40 years and will write off that goodwill
as a noncash operating expense over this period.



     On May 19, 1999, the Financial Accounting Standards Board tentatively
decided to reduce the current maximum write-off period of 40 years for goodwill
to 20 years for most companies. We understand the 20-year write-off period may
apply only to acquisitions occurring after a future date the FASB will set. We
understand the FASB will issue a formal proposal on this subject for public
comment later in the year.



     If this FASB proposal results in a change in generally accepted accounting
principles we may be required to accelerate the rate at which we recognize
expense resulting from our goodwill. Any such acceleration would cause our
reported earnings to decrease for some period of time.



     In addition to the goodwill amortization issue described above, some
members of management and founders received stock in connection with the
organization of our company. The applicable accounting rules require that the
stock issued to some of these members of our management be treated as
compensation expense. As a result of this treatment, we recorded a non-recurring
non-cash charge on April 1, 1999 of approximately $7.7 million which will reduce
our EBITDA and net income and is

                                       13
<PAGE>   20

reflected in our second quarter results. See "Unaudited Pro Forma Combined
Financial Statements" and the Notes thereto.

- -- A FAILURE ON OUR PART TO SUCCESSFULLY INTEGRATE THE FOUNDING COMPANIES COULD
   HAVE A MATERIAL ADVERSE EFFECT ON OUR FUTURE FINANCIAL RESULTS.

     The founding companies have been operating and will continue to operate as
separate independent entities, and we cannot guarantee that we will be able to
integrate these businesses on an economic basis. In addition, we cannot
guarantee that the recently assembled management group will be able to oversee
the combined entity and effectively implement our operating or growth
strategies. Until we establish centralized accounting and other administrative
systems, we will rely on the systems used by the founding companies. If we are
unable to successfully coordinate and integrate the founding companies and
future acquisitions into AMPAM, including their accounting and administrative
functions and other banking and insurance functions and computer systems, then
our business, financial condition and results of operations may be materially
and adversely affected.

- -- OUR GROWTH COULD BE DIFFICULT TO MANAGE. AN ACTIVELY GROWING COMPANY LIKE
   OURS REQUIRES THE CONSTANT ATTENTION OF ITS MANAGEMENT. IF TOO MUCH OF OUR
   MANAGEMENT'S TIME IS SPENT ATTENDING TO THE GROWTH OF AMPAM, OUR OPERATIONS
   COULD SUFFER.

     If we are unable to manage our growth, or if we are unable to attract and
retain additional qualified management, there could be a material adverse effect
on our financial condition and results of operations. As we continue to grow,
there can be no assurance that our management group will be able to oversee
AMPAM and effectively implement our operating or growth strategies. We expect
our management will expend time and effort in evaluating, completing and
integrating acquisitions and opening new facilities. We cannot guarantee that
our systems, procedures and controls will be adequate to support our expanding
operations, including the timely receipt of financial information from acquired
companies.

     A key point of our business strategy is to grow by acquiring other plumbing
and mechanical contracting service companies. We cannot guarantee that we will
be able to acquire additional businesses or integrate and manage them
successfully. We cannot assure you that the businesses we acquire will achieve
sales and profitability that justify our investment.

     Acquisitions we make may involve additional issues, including:

     - adverse short-term effects on our financial results;

     - diversion of our management's attention;

     - dependence on retention, hiring and training of key personnel; and

     - risks associated with unanticipated problems or legal liabilities.

     Although we believe we are the first company to focus primarily on
consolidating the plumbing and mechanical contracting service industry, we also
believe that the industry will continue to experience consolidation on both a
national and a regional level as existing consolidators focusing on related
industries pursue their acquisition strategies or as other companies develop
acquisition objectives similar to those of our company. In addition, we cannot
guarantee that other existing companies consolidating related industries or
yet-to-be-formed companies will not also adopt a similar focus and compete with
our company for acquisition candidates in plumbing and mechanical contracting
services and related industries. These competitors may have greater financial
resources than our company to finance acquisitions and internal growth
opportunities and might be willing to pay higher prices for the same acquisition
opportunities. This competition could have the effect of increasing the price
for acquisitions or reducing the number of suitable acquisition candidates. If
these types of acquisitions can be made, we cannot give any assurance that
businesses acquired will achieve sales and profitability that justify the
investment.

                                       14
<PAGE>   21

- -- IF WE ARE UNABLE TO OBTAIN A SIGNIFICANT AMOUNT OF ADDITIONAL CAPITAL, WE MAY
   NOT BE ABLE TO SUCCESSFULLY IMPLEMENT OUR GROWTH STRATEGY WHICH COULD HAVE A
   MATERIAL ADVERSE EFFECT ON OUR FUTURE FINANCIAL RESULTS.

     The expansion of our company through our acquisition program will require
significant capital. The timing, size and success of our acquisition efforts and
the associated capital commitments cannot be readily predicted. We currently
intend to use common stock for a portion of the consideration used in future
acquisitions. If potential acquisition candidates are unwilling to accept common
stock as part of the consideration for the sale of their businesses, we may be
required to use more of our cash resources, if available, to pursue our
acquisition program. If we do not have enough cash resources, our growth could
be limited unless we are able to obtain additional capital through future debt
or equity financings, including borrowings under existing credit facilities. If
incurred, this indebtedness would increase our leverage, may make us more
vulnerable to economic downturns and may limit our ability to withstand
competitive pressures.

     We have put into place a credit facility to be used for working capital,
capital expenditures and other general corporate purposes. Although we believe
this credit facility will be sufficient, we cannot guarantee that it will be
able to entirely fund our acquisition program. Additionally, this credit
facility includes financial covenants that limit our operations and financial
flexibility. As a result, we might be limited in our ability to pursue our
acquisition strategy successfully which could have a negative impact on our
financial results.

- -- FUTURE ACQUISITIONS COULD CHANGE OUR CAPITAL AND DEBT STRUCTURE AND COULD
   HAVE A MATERIAL ADVERSE EFFECT ON OUR RESULTS OF OPERATIONS.

     Although AMPAM does not currently have any agreements or understandings
with respect to the acquisition of any company or business, AMPAM may in the
future enter into discussions or negotiations with potential acquisition
candidates engaged in the plumbing, mechanical, utility installation or HVAC or
related businesses. Negotiations may result in agreements to acquire one or more
companies or businesses or their assets. In connection with any acquisition of
this type, the consideration payable by AMPAM may consist of shares of common
stock, cash, promissory notes or other securities of AMPAM or a combination of
these types of consideration. Accordingly, if AMPAM enters into agreements to
acquire one or more companies or businesses after the date of this prospectus,
the capitalization of AMPAM is likely to differ, possibly significantly, from
the capitalization reflected in this prospectus. In particular, the number of
shares of common stock that would be issued and outstanding, the amount of
indebtedness and the amount of working capital as of the date of the closing of
any future acquisitions may be significantly different from the amounts
reflected in this prospectus. In addition, if AMPAM enters into agreements to
acquire one or more companies or businesses after the date of this prospectus,
the pro forma financial statements of AMPAM are likely to differ from the pro
forma financial statements included in this prospectus.

- -- THERE IS CURRENTLY A SHORTAGE OF QUALIFIED PLUMBERS AND TECHNICIANS. SINCE
   THE MAJORITY OF OUR WORK IS PERFORMED BY PLUMBERS AND TECHNICIANS, THIS
   SHORTAGE COULD LIMIT OUR ABILITY TO GROW.

     We are dependent upon an adequate supply of skilled personnel to complete
our plumbing and mechanical contracts on time. The supply of skilled personnel
is sensitive to economic and competitive conditions and the level of demand for
plumbing and mechanical contracting services. Many companies in the plumbing and
mechanical contracting services industry are currently experiencing shortages of
qualified personnel, and as a result there is significant competition for
skilled labor. Accordingly, our ability to increase productivity and
profitability may be limited by our ability to employ, train and retain the
skilled personnel necessary to meet our service requirements. In addition, labor
shortages could result in wage

                                       15
<PAGE>   22

increases, which could reduce our operating margins and have a negative effect
on our financial condition and results of operations. We cannot guarantee that,
among other things:

     - we will be able to maintain the skilled labor force necessary to operate
       efficiently;
     - our labor expenses will not increase as a result of a shortage in the
       skilled labor supply; or
     - we will not have to curtail internal growth as a result of labor
       shortages.

- -- THE LOSS OF A GROUP OF KEY PERSONNEL, EITHER AT THE CORPORATE OR OPERATING
   LEVEL, COULD ADVERSELY AFFECT OUR BUSINESS.

     Because we intend to continue to operate on a decentralized basis, our
operations will continue to depend on the efforts and experience of our
executive officers and the senior management of the founding companies.
Furthermore, we will depend on the senior management of companies that may be
acquired in the future. Although we have entered into employment agreements with
some of our executive officers, we cannot guarantee that any individual will
continue in their capacity for any particular period of time. We have not
entered into employment agreements with some of the members of management of the
founding companies. Also, we may not enter into employment agreements with
members of management of additional companies that we may acquire in the future.
The loss of key personnel or the inability to hire and retain qualified
employees could have a material adverse effect on our business, financial
condition and results of operations. We do not maintain key man life insurance.

- -- THE HIGHLY COMPETITIVE NATURE OF OUR INDUSTRY COULD AFFECT OUR PROFITABILITY
   BY REDUCING OUR PROFIT MARGINS.

     The plumbing and mechanical contracting services industry is highly
fragmented and competitive. The industry is generally served by a large number
of small, owner-operated private companies and by several large companies that
provide plumbing and mechanical contracting services (often on an ancillary
basis to an HVAC business) on a regional or national basis. We will compete with
other consolidators, including those focused on the HVAC business, that also
provide some plumbing and mechanical contracting services. We could also face
competition in the future from other competitors entering the market. Some of
our competitors may have greater financial resources or may achieve greater
efficiencies which may allow these competitors the ability to provide a greater
range of services, provide services in a larger number of locations or offer
services at lower prices. In some geographic regions, we may not be eligible to
compete for contracts because our employees are not subject to collective
bargaining agreements.

- -- THE ESTIMATES WE USE IN PLACING BIDS COULD BE MATERIALLY INCORRECT. THE USE
   OF INCORRECT ESTIMATES COULD RESULT IN LOSSES ON A FIXED PRICE CONTRACT.
   THESE LOSSES COULD BE MATERIAL TO OUR BUSINESS.

     Nearly all of our plumbing and mechanical contracting services are
performed under fixed price contracts, so the risk of cost overruns on a given
project is generally borne by our company. Our ability to remain profitable
depends in part on our ability to accurately estimate the material and labor
costs of completing plumbing and mechanical installation projects. From time to
time, market conditions in a given geographic area can cause increases in
skilled labor costs, and disruptions in the supply of plumbing and mechanical
materials can cause cost increases, either directly or through delays in
delivery of materials. Costs can also be affected by delays caused by weather,
other contractors working on a given project or other factors beyond our
control. Increases in costs caused by any of these factors could have material
adverse effects on our business, financial condition and results of operation.

- -- OUR INDUSTRY EXPERIENCES UPTURNS AND DOWNTURNS, DEPENDING ON THE SEASON OF
   THE YEAR AND THIS COULD HAVE AN ADVERSE EFFECT ON OUR QUARTERLY OPERATING
   RESULTS.

     The plumbing and mechanical contracting services industry is influenced by
seasonal declines in operations and demand that affect the construction
business. These declines can result in lower activity levels during the first
and fourth quarters than in other periods. There can be no assurance that our
combined geographic, service and product mix will be sufficient to overcome any
declines that may occur

                                       16
<PAGE>   23

in the future or that seasonal patterns will not emerge. Quarterly results may
also be materially affected by the timing of acquisitions, the timing and
magnitude of costs relating to the assimilation of acquired companies and
regional economic conditions. Accordingly, performance in any particular quarter
may not indicate the results which can be expected for any other quarter or for
the entire year.

- -- THE FOUNDING COMPANIES HAVE SIGNIFICANT CUSTOMER CONCENTRATION AND IF A
   FOUNDING COMPANY WERE TO LOSE A SIGNIFICANT CUSTOMER, THIS COULD HAVE A
   MATERIAL ADVERSE EFFECT ON THE RESULTS OF OPERATIONS OF THAT PARTICULAR
   SUBSIDIARY.

     Although no individual customer of AMPAM accounts for more than 5% of our
revenues, some founding companies have customers that account for up to 63% of
their revenues. Although the loss of anyone of these customers would not have a
material adverse affect on us, this type of loss could significantly and
negatively affect the business, financial condition and results of operations of
a founding company.

- -- WE ARE REQUIRED TO COMPLY WITH A NUMBER OF OPERATIONAL AND LICENSING
   REQUIREMENTS. IF WE WERE TO LOSE A LICENSE OR WERE UNABLE TO OBTAIN A RENEWAL
   OF A LICENSE, OUR ABILITY TO OPERATE IN A PARTICULAR AREA MAY BE IMPAIRED

     Our business and the activities of our plumbing and mechanical contracting
service providers are subject to various federal, state and local laws,
regulations, ordinances and policies. Areas of governmental involvement include:

     - the licensing and certification of plumbers and technicians;
     - our advertising, warranties and disclosures to its customers;
     - the bidding process required to obtain plumbing and mechanical contracts;
       and
     - the applicable plumbing, mechanical and building codes with which we must
       comply.

     Most states require at least one of our employees to be a licensed master
plumber, and many jurisdictions regulate the number and level of license holders
who must be present on a construction site during the installation of plumbing
and mechanical systems. Some jurisdictions require us to obtain a building
permit for each plumbing or mechanical project. In addition, we must comply with
labor laws and regulations, including those that relate to verification by
employers of legal immigration or work permit status of employees.

     We believe that each of the founding companies holds all of the licenses
and permits required to conduct business in the jurisdictions in which we
operate, and our employees in each of these jurisdictions have knowledge of the
specifications of the applicable construction codes. However, as a result of our
expansion, in the future we may operate in jurisdictions where we will need to
employ persons with the required licenses and knowledge and we cannot guarantee
that we will be able to do so. Furthermore, applicable regulations may change
and may increase expenses or cause project delays. We cannot guarantee that
existing or new laws or regulations applicable to our business will not have a
material adverse effect on our business, financial condition and results of
operations.

- -- COMPLIANCE WITH OR ENVIRONMENTAL, HEALTH AND SAFETY REGULATIONS COULD HAVE A
   SIGNIFICANT NEGATIVE EFFECT ON OUR FINANCIAL RESULTS.

     We are subject to safety standards established and enforced by the
Occupational Safety and Health Administration and environmental laws and
regulations relating to the use, storage, transportation and disposal of various
materials. To the extent that we perform work involving air conditioning and
refrigeration systems, we are subject to additional restrictions and regulations
governing the availability, handling and recycling of refrigerants. While we
believe that we are in substantial compliance with all applicable laws and
regulations, these regulations may change and may increase expenses or cause
project delays. We cannot guarantee that existing or new laws or regulations
applicable to our business will not have a material adverse effect on our
business, financial condition and results of operations.

                                       17
<PAGE>   24

     Some of the founding companies utilize underground or aboveground storage
tanks for motor fuels and other materials. Many of the founding companies'
facilities are located in industrial sectors, where contamination may result
from the activities of prior occupants or neighbors. Some environmental laws and
regulations impose liability on the operator of a tank or a facility at which
contamination is present, regardless of fault. While we know of no contamination
affecting any of the tanks or facilities which it will operate, we cannot
guarantee that undiscovered contamination does not exist, and that this
contamination will not have a material adverse effect on our business, financial
condition and results of operations.

- -- OUR OPERATIONS ARE SUBJECT TO NUMEROUS PHYSICAL HAZARDS ASSOCIATED WITH THE
   CONSTRUCTION OF PLUMBING AND MECHANICAL SYSTEMS. IF AN ACCIDENT OCCURS,
   CLAIMS AGAINST US COULD EXCEED LEVELS COVERED BY OUR INSURANCE AND COULD
   SIGNIFICANTLY HARM OUR BUSINESS.

     The nature of our business exposes us to potential claims for personal
injury or death resulting from injuries to our employees and other persons,
property damage and negligence, intentional misconduct or defective materials or
workmanship in connection with the installation, repair or maintenance of
plumbing, mechanical and maintenance systems. Claims made by our customers may
be based on the warranties we provide with respect to materials or workmanship
or may be based on common law or state statutes relating to the conduct of
contractors. Although each of the founding companies is covered by comprehensive
insurance, subject to deductibles, various types of claims, such as claims for
punitive damages or damages arising from intentional misconduct, are generally
not covered by insurance. We cannot guarantee that existing or future claims
would not exceed our level of insurance or the level of insurance of the
founding companies, or that insurance will continue to be available on
economically reasonable terms, if at all.

- -- WE MAY NOT HAVE THE ABILITY TO RAISE THE FUNDS NECESSARY TO FINANCE THE
   CHANGE OF CONTROL OFFER REQUIRED BY THE INDENTURE AND TO SIMULTANEOUSLY REPAY
   THE CREDIT FACILITY. ADDITIONALLY, WE MAY NOT HAVE THE ABILITY TO RAISE THE
   FUNDS NECESSARY TO REPAY THE NOTES AND THE CREDIT FACILITY SIMULTANEOUSLY IF
   PAYMENT UNDER THE CREDIT FACILITY IS ACCELERATED FOLLOWING AN EVENT OF
   DEFAULT THAT IN TURN CAUSES AN EVENT OF DEFAULT UNDER THE INDENTURE.

     On the occurrence of specific kinds of change of control events we will be
required to offer to repurchase all outstanding notes and may also be required
to repay all amounts outstanding under our credit facility. Similarly, if we are
in default under our credit facility, it could trigger a default under the
notes, requiring us to both repay all amounts outstanding under the credit
facility as well as all of the outstanding notes. It is possible that we will
not have sufficient funds at the time of the change of control to make the
required repurchase of notes or that restrictions in our credit facility will
not allow these repurchases. The same applies in the case of an event of
default. In addition, important corporate events, like leveraged
recapitalizations that would increase the level of our indebtedness, would not
constitute a "Change of Control" under the indenture. See "Description of the
Notes -- Change of Control" and "--Events of Default."

- -- FEDERAL AND STATE STATUTES ALLOW COURTS, UNDER SPECIFIC CIRCUMSTANCES, TO
   VOID GUARANTEES AND REQUIRE NOTEHOLDERS TO RETURN PAYMENTS RECEIVED FROM
   GUARANTORS. THESE STATUTES COULD CAUSE THE GUARANTEES TO BE WORTHLESS TO YOU.
   ALSO, IF YOU HAVE RECEIVED PAYMENTS FROM OUR GUARANTORS, YOU COULD BE
   REQUIRED TO FORFEIT THOSE PAYMENTS.

     Under the federal bankruptcy laws and comparable provisions of state
fraudulent transfer laws, a guarantee could be voided, or claims in respect of a
guarantee could be subordinated to all other debts of that guarantor if, among
other things, the guarantor, at the time it incurred the indebtedness evidenced
by its guarantee received less than reasonably equivalent value or fair
consideration for the incurrence of this guarantee, and;

     - was insolvent or rendered insolvent by reason of the incurrence;
     - or was engaged in a business or transaction for which the guarantor's
       remaining assets constituted unreasonably small capital; or
                                       18
<PAGE>   25

     - intended to incur, or believed that it would incur, debts beyond its
       ability to pay these debts as they mature.

     In addition, any payment by that guarantor under the terms of its guarantee
could be voided and required to be returned to the guarantor or to a fund for
the benefit of the creditors of the guarantor.

     The measures of insolvency for purposes of these fraudulent transfer laws
will vary depending upon the law applied in any proceeding to determine whether
a fraudulent transfer has occurred. Generally, however, a guarantor would be
considered insolvent if:

     - the sum of its debts, including contingent liabilities, were greater than
       the fair saleable value of all of its assets; or
     - if the present fair saleable value of its assets were less than the
       amount that would be required to pay its probable liability on its
       existing debts, including contingent liabilities, as they become absolute
       and mature; or
     - it could not pay its debts as they become due.

     On the basis of historical financial information, recent operating history
and other factors, we believe that each subsidiary guarantor, after giving
effect to its guarantee of these notes, will not be insolvent, will not have
unreasonably small capital for the business in which it is engaged and will not
have incurred debts beyond its ability to pay these debts as they mature. There
can be no assurance, however, as to what standard a court would apply in making
these determinations or that a court would agree with our conclusions in this
regard.

- -- YOU CANNOT BE SURE THAT AN ACTIVE TRADING MARKET WILL DEVELOP FOR THESE
   NOTES.

     Prior to this offering, there was no public market for these notes. Firms
making a market in these notes may cease their market-making at any time. In
addition, the liquidity of the trading market in these notes, and the market
price quoted for these notes, may be adversely affected by changes in the
overall market for high yield securities and by changes in our financial
performance or prospects or in the prospects for companies in our industry
generally. As a result, you cannot be sure than an active trading market will
develop for these notes.

- -- COMPUTER SYSTEMS WE RELY ON MAY FAIL TO RECOGNIZE YEAR 2000. A FAILURE COULD
   RESULT IN DISRUPTIONS OF OUR OPERATIONS AND OUR ACCOUNTING SYSTEMS.

     We are in the process of identifying and evaluating potential issues for
its information technology and third party relationships associated with the
date change in the year 2000. We have not yet fully assessed any year 2000
remedial costs, but we are in the process of identifying and developing
solutions to the year 2000 issues. Although we are not currently able to
quantify the cost of corrective actions, we do not expect that these actions
will materially exceed the cost of normal software upgrades and replacements
expected to occur through the year 2000. We believe that all necessary work will
be completed in a timely fashion, but we cannot guarantee that the systems of
other companies on which we rely will be converted within the same time frame.
We are attempting to obtain assurances from vendors, business partners, and
others with which we conduct business that their systems will be year 2000
compliant. If as a result of foregoing process we determine that a material
business interruption may occur due to the year 2000 issue, we will attempt to
implement an appropriate contingency plan. Any material failure of our company
or others to bring the computer systems on which we rely into compliance with
year 2000 requirements could result in additional costs of corrective actions
and delays in preparing contract bids, receiving payment on completed contracts,
integrating the reporting systems of the founding companies and implementing our
strategies. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Year 2000."

                           FORWARD-LOOKING STATEMENTS

     This prospectus includes forward-looking statements. We have based these
forward-looking statements on our current expectations and projections about
future events. These forward-looking statements are subject to risks,
uncertainties, and assumptions about our company, including, among other things:

     - Our anticipated growth strategies,

     - Our ability to make acquisitions,

     - Our ability to integrate acquired businesses,

     - Our ability to gain efficiencies through consolidation,

     - Anticipated trends in our businesses,

     - Future expenditures for capital projects,

     - Our ability to continue to control costs and maintain quality, and

     - Our ability to compete.

     We undertake no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future events or otherwise.
In light of these risks, uncertainties, and assumptions, the forward-looking
events discussed in this prospectus might not occur.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     We sold the existing notes on May 19, 1999, to Fleet Securities, Inc.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated, Banc One Capital Markets,
Inc. and Credit Lyonnais Securities (USA), Inc. under a purchase agreement.
These initial purchasers then sold the existing notes to qualified institutional
buyers in reliance on Rule 144A under the Securities Act. As a condition to the
purchase of the existing notes by the initial purchasers, AMPAM and the
guarantors entered into a registration rights agreement with the initial
purchasers, which requires, among other things, that promptly following the sale
of the existing notes, AMPAM and the guarantors:

     - file with the Commission the registration statement related to the
       exchange notes;

     - use their reasonable best efforts to cause the registration statement to
       become effective under the Securities Act; and

     - offer to the holders of the existing notes the opportunity to exchange
       their existing notes for a like principal amount of exchange notes upon
       the effectiveness of the registration statement.

     The exchange notes will be issued without a restrictive legend and may be
reoffered and resold without restrictions or limitations under the Securities
Act. A copy of the registration rights agreement has been filed as an exhibit to
the registration statement of which this prospectus is a part. The term "holder"
means any person in whose name existing notes are registered on AMPAM's books.

     Based on existing interpretations of the Securities Act by the staff of the
SEC described in several no-action letters to third parties, and subject to the
following sentence, we believe that the exchange notes issued in the exchange
offer may be offered for resale, resold and otherwise transferred by their
holders, other than broker-dealers or "affiliates" of AMPAM, without further
compliance with the registration and prospectus delivery provisions of the
Securities Act. However, any purchaser of notes who is an affiliate of AMPAM or
who intends to participate in the exchange offer for the purpose of distributing
the exchange notes, or any broker-dealer who purchased the notes from AMPAM to
resell under Rule 144A or any other available exemption under the Securities
Act:

     - will not be able to rely on the interpretations by the staff of the
       Commission described in the above-mentioned no-action letters;

     - will not be able to tender its notes in the exchange offer; and

     - must comply with the registration and prospectus delivery requirements of
       the Securities Act in connection with any sale or transfer of the notes
       unless the sale or transfer is made under an exemption from these
       requirements.

     We do not intend to seek our own no-action letter, and there is no
assurance that the staff of the Commission would make a similar determination
regarding the exchange notes as it has in these no-action letters to third
parties. See "Plan of Distribution."

     As a result of the filing and effectiveness of the registration statement
of which this prospectus is a part, AMPAM and the guarantors will not be
required to pay an increased interest rate on the existing notes. Following the
closing of the exchange offer, holders of existing notes not tendered will not
have any further registration rights except in limited circumstances requiring
the filing of a shelf registration statement, and the existing notes will
continue to be subject to restrictions on transfer. Accordingly, the liquidity
of the market for the existing notes could be adversely affected.

TERMS OF THE EXCHANGE OFFER

     Upon the terms and subject to the conditions stated in this prospectus and
in the letter of transmittal, we will accept all existing notes properly
tendered and not withdrawn prior to 5:00 p.m. New York City
                                       21
<PAGE>   28

time, on the expiration date. After authentication of the exchange notes by the
trustee or an authenticating agent, we will issue $1,000 principal amount of
exchange notes in exchange for each $1,000 principal amount of outstanding
existing notes accepted in the exchange offer. Holders may tender some or all of
their existing notes in denominations of $1,000 or any integral multiple of
$1,000.

     Each holder of the notes who wishes to exchange notes in the exchange offer
will be required to represent that:

     - it is not an affiliate of AMPAM or any guarantor;

     - any exchange notes to be received by it were acquired in the ordinary
       course of its business; and

     - it has no arrangement with any person to participate in the distribution
       of the exchange notes.

     Each broker-dealer that receives exchange notes for its own account under
the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of the exchange notes. The letter of transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be judged to have admitted that it is an "underwriter" within the
meaning of the Securities Act. The SEC has taken the position that participating
broker-dealers may fulfill their prospectus delivery requirements related to the
exchange notes with the prospectus contained in the exchange offer registration
statement, other than a resale of an unsold allotment from the original sale of
the notes. AMPAM will be required to allow participating broker-dealers to use
the prospectus contained in the exchange offer registration statement following
the exchange offer, in connection with the resale of exchange notes received in
exchange for notes acquired by participating broker-dealers for their own
account as a result of market-making or other trading activities. We will not be
required to allow participating broker-dealers to use this prospectus if we
determine, after being advised by our attorneys, that the continued use of the
prospectus would (1) require us to disclose material information that we have a
legitimate business reason for keeping confidential or (2) interfere with a
material transaction in which AMPAM or our subsidiaries is involved. See "Plan
of Distribution."

     The form and terms of the exchange notes are identical in all material
respects to the form and terms of the existing notes except that:

     - the exchange notes will be issued in a transaction registered under the
       Securities Act;

     - the exchange notes will not be subject to transfer restrictions; and

     - provisions relating to an increase in the stated interest rate on the
       existing notes provided for in some circumstances will be eliminated.

     The exchange notes will evidence the same debt as the existing notes. The
exchange notes will be issued under and entitled to the benefits of the
indenture.

     As of the date of this prospectus, $125,000,000 aggregate principal amount
of the existing notes was outstanding. In connection with the issuance of the
existing notes, we arranged for the existing notes, which were initially
purchased by qualified institutional buyers as defined under Rule 144A under the
Securities Act, to be issued and transferable in book-entry form through the
facilities of the depositary, acting as depositary. The exchange notes will also
be issuable and transferable in book-entry form through the depositary.

     This prospectus, together with the accompanying letter of transmittal, is
initially being sent to all registered holders as of the close of business on
          , 1999. We intend to conduct the exchange offer as required by the
Exchange Act, and the rules and regulations of the Commission under the Exchange
Act, including Rule 14e-1, to the extent applicable.

     Rule 14e-1 describes unlawful tender practices under the Exchange Act. This
section requires us, among other things:

     - to hold our exchange offer open for twenty business days;
                                       22
<PAGE>   29

     - to give ten days notice of any change in the terms of this offer; and

     - to issue a press release in the event of an extension of the exchange
       offer.

     The exchange offer is not conditioned upon any minimum aggregate principal
amount of existing notes being tendered, and holders of the existing notes do
not have any appraisal or dissenters' rights under the General Corporation Law
of the State of Delaware or under the indenture in connection with the exchange
offer. We shall be considered to have accepted existing notes tendered according
to the procedures in this prospectus when, as and if we have given oral or
written notice of acceptance to the exchange agent. See "-- Exchange Agent." The
exchange agent will act as agent for the tendering holders for the purpose of
receiving exchange notes from us and delivering exchange notes to those holders.

     If any tendered existing notes are not accepted for exchange because of an
invalid tender or the occurrence of other events described in this prospectus,
certificates for these unaccepted existing notes will be returned, at our cost,
to the tendering holder of the existing notes as promptly as practicable after
the expiration date.

     Holders who tender existing notes in the exchange offer will not be
required to pay brokerage commissions or fees or, subject to the instructions in
the letter of transmittal, transfer taxes related to the exchange of existing
notes in the exchange offer. We will pay all charges and expenses, other than
applicable taxes, in connection with the exchange offer. See "-- Solicitation of
Tenders; Fees and Expenses."

     NEITHER THE BOARD OF DIRECTORS OF AMPAM NOR AMPAM MAKES ANY RECOMMENDATION
TO HOLDERS OF EXISTING NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING
ALL OR ANY PORTION OF THEIR EXISTING NOTES UNDER TO THE EXCHANGE OFFER.
MOREOVER, NO ONE HAS BEEN AUTHORIZED TO MAKE ANY RECOMMENDATION. HOLDERS OF
EXISTING NOTES MUST MAKE THEIR OWN DECISION WHETHER TO TENDER IN THE EXCHANGE
OFFER AND, IF SO, THE AMOUNT OF EXISTING NOTES TO TENDER AFTER READING THIS
PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR ADVISORS, IF
ANY, BASED ON THEIR OWN FINANCIAL POSITION AND REQUIREMENTS.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

     The term "expiration date" shall mean 5:00 p.m., New York City time, on
          , 1999, unless we, in our sole discretion, extend the exchange offer,
in which case the term "expiration date" shall mean the latest date to which the
exchange offer is extended.

     We expressly reserve the right, in our sole discretion:

          (1) to delay acceptance of any existing notes, to extend the exchange
     offer or to terminate the exchange offer and to refuse to accept existing
     notes not previously accepted, if any of the conditions described in this
     prospectus under "-- Conditions" shall have occurred and shall not have
     been waived by us (if permitted to be waived by us), by giving oral or
     written notice of the delay, extension or termination to the exchange
     agent; and

          (2) to amend the terms of the exchange offer in any manner.

     Any delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice of the delay in
acceptance by us to the registered holders of the existing notes. If the
exchange offer is amended in a manner determined by us to constitute a material
change, we will promptly disclose the amendment in a manner reasonably
calculated to inform the holders of the amendment.

     Without limiting the manner in which we may choose to make public
announcements of any delay in acceptance, extension, termination or amendment of
the exchange offer, we shall have no obligation to publish, advise, or otherwise
communicate any public announcement, other than by making a timely release to
the Dow Jones News Service.

                                       23
<PAGE>   30

     You are advised that AMPAM may extend the exchange offer because some
portion of the notes may not tender on a timely basis. In order to give these
noteholders the ability to participate in the exchange and to avoid the
significant reduction in liquidity associated with holding an unexchanged note,
AMPAM may elect to extend the exchange offer.

INTEREST ON THE EXCHANGE NOTES

     The exchange notes will bear interest from the date of issuance of the
existing notes that are tendered in exchange for the exchange notes (or the most
recent date on which interest was paid or provided for on the existing notes
surrendered for the exchange notes). Accordingly, holders of existing notes that
are accepted for exchange will not receive interest that is accrued but unpaid
on the existing notes at the time of tender. Interest on the exchange notes will
be payable semi-annually on each April 15 and October 15, commencing on October
15, 1999.

PROCEDURES FOR TENDERING

     Only a holder may tender its existing notes in the exchange offer. To
tender in the exchange offer, a holder must complete, sign and date the letter
of transmittal or a facsimile of the letter of transmittal, have the signatures
guaranteed if required by the letter of transmittal, and mail or otherwise
deliver the letter of transmittal or the facsimile, together with the existing
notes (unless the tender is being effected under the procedure for book-entry
transfer described below) and any other required documents, to the exchange
agent, prior to 5:00 p.m. New York City time, on the expiration date.

     Any financial institution that is a participant in the depositary's
book-entry transfer facility system may make book-entry delivery of the existing
notes by causing the depositary to transfer the existing notes into the exchange
agent's account using the depositary's procedure for the transfer. Although
delivery of existing notes may be effected through book-entry transfer into the
exchange agent's account at the depositary, the letter of transmittal (or
facsimile), with any required signature guarantees and any other required
documents, must, in any case, be transmitted to and received by the exchange
agent at its address listed in this prospectus under "-- Exchange Agent" prior
to 5:00 p.m., New York City time, on the expiration date. DELIVERY OF DOCUMENTS
TO THE DEPOSITARY USING ITS PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE
EXCHANGE AGENT.

     The tender by a holder will constitute an agreement between the holder,
AMPAM and the exchange agent according to the terms and subject to the
conditions described in this prospectus and in the letter of transmittal.

     In the case of a broker-dealer that receives exchange notes for its own
account in exchange for existing notes which were acquired by it as a result of
market-making or other trading activities, the letter of transmittal will also
include an acknowledgment that the broker-dealer will deliver a copy of this
prospectus in connection with the resale by it of exchange notes received in the
exchange offer. See "Plan of Distribution."

     THE METHOD OF DELIVERY OF EXISTING NOTES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDERS. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE
AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT PRIOR TO THE EXPIRATION DATE.
NO LETTER OF TRANSMITTAL OR EXISTING NOTES SHOULD BE SENT TO US. HOLDERS MAY
ALSO REQUEST THAT THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES OR NOMINEES EFFECT THE TENDER FOR HOLDERS IN EACH CASE AS DESCRIBED IN
THIS PROSPECTUS AND IN THE LETTER OF TRANSMITTAL.

     Any beneficial owner whose existing notes are registered in the name of his
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct the
registered holder to tender on his behalf. If the beneficial owner wishes to
tender on his own behalf, the beneficial owner must, prior to completing and
executing the letter of transmittal and delivering his existing notes, either
make appropriate arrangements to register ownership of

                                       24
<PAGE>   31

the existing notes in the owner's name or obtain a properly completed bond power
from the registered holder. The transfer of record ownership may take
considerable time.

     Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by a member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.
or a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act unless the existing notes tendered with the
letter of transmittal are tendered (1) by a registered holder who has not
completed the box entitled "Special Registration Instructions" or "Special
Delivery Instructions" of the letter of transmittal or (2) for the account of an
eligible institution. If the letter of transmittal is signed by a person other
than the registered holder, the existing notes must be endorsed or accompanied
by appropriate bond powers which authorize the person to tender the existing
notes on behalf of the registered holder, in either case signed as the name of
the registered holder or holders appears on the existing notes. If the letter of
transmittal or any existing notes or bond powers are signed or endorsed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, those
persons should so indicate when signing, and unless waived by us, evidence
satisfactory to us of their authority to so act must be submitted with the
letter of transmittal.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of the tendered existing notes will be
determined by us in our sole discretion. This determination will be final and
binding. We reserve the absolute right to reject any and all existing notes not
properly tendered or any existing notes our acceptance of which would, in the
opinion of our counsel, be unlawful. We also reserve the absolute right to waive
any irregularities or conditions of tender as to particular existing notes. Our
interpretation of the terms and conditions of the exchange offer (including the
instructions in the letter of transmittal) will be final and binding on all
parties. Unless waived, any defects or irregularities in connection with tenders
of existing notes must be cured within the time as we shall determine. Although
we intend to notify holders of defects or irregularities related to tenders of
existing notes, neither we, the exchange agent nor any other person shall be
under any duty to give notification of defects or irregularities related to
tenders of existing notes nor shall any of them incur liability for failure to
give notification. Tenders of existing notes will not be considered to have been
made until the irregularities have been cured or waived. Any existing notes
received by the exchange agent that we determine are not properly tendered or
the tender of which is otherwise rejected by us and as to which the defects or
irregularities have not been cured or waived by us will be returned by the
exchange agent to the tendering holder unless otherwise provided in the letter
of transmittal, as soon as practicable following the expiration date.

     In addition, we reserve the right in our sole discretion to (1) purchase or
make offers for any existing notes that remain outstanding subsequent to the
expiration date, or, as described under "-- Termination," to terminate the
exchange offer and (2) to the extent permitted by applicable law, purchase
existing notes in the open market, in privately negotiated transactions or
otherwise. The terms of these purchases or offers may differ from the terms of
the exchange offer.

BOOK-ENTRY TRANSFER

     We understand that the exchange agent will make a request promptly after
the date of this prospectus to establish accounts for the existing notes at the
DTC for the purpose of facilitating the exchange offer, and subject to their
establishment, any financial institution that is a participant in the book-entry
transfer facility's system may make book-entry delivery of existing notes by
causing the book-entry transfer facility to transfer the existing notes into the
exchange agent's account for the existing notes using the book-entry transfer
facility's procedures for transfer. Although delivery of existing notes may be
effected through book-entry transfer into the exchange agent's account at the
book-entry transfer facility, an appropriate letter of transmittal properly
completed and duly executed with any required signature guarantee and all other
required documents must in each case be transmitted to and received or confirmed
by the exchange agent at its address listed below on or prior to the expiration
date, or, if the guaranteed delivery procedures
                                       25
<PAGE>   32

described below are complied with, with the time period provided under the
procedures. Delivery of documents to the book-entry transfer facility does not
constitute delivery to the exchange agent.

GUARANTEED DELIVERY PROCEDURES

     Holders who wish to tender their existing notes and (1) whose existing
notes are not immediately available, or (2) who cannot deliver their existing
notes, the letter of transmittal or any other required documents to the exchange
agent prior to the expiration date, or if the holder cannot complete the
procedure for book-entry transfer on a timely basis, may effect a tender if:

     - the tender is made through an eligible institution;

     - prior to the expiration date, the exchange agent receives from an
       eligible institution a properly completed and duly executed notice of
       guaranteed delivery (by facsimile transmittal, mail or hand delivery)
       setting forth the name and address of the holder, the certificate number
       or numbers of the holder's existing notes and the principal amount of the
       existing notes tendered, stating that the tender is being made, and
       guaranteeing that, within five business days after the expiration date,
       the letter of transmittal (or facsimile), together with the
       certificate(s) representing the existing notes to be tendered in proper
       form for transfer and any other documents required by the letter of
       transmittal will be deposited by the eligible institution with the
       exchange agent; and

     - the properly completed and executed letter of transmittal (or a
       facsimile), together with the certificate(s) representing all tendered
       existing notes in proper form for transfer (or confirmation of a
       book-entry transfer into the exchange agent's account at the depositary
       of existing notes delivered electronically) and all other documents
       required by the letter of transmittal are received by the exchange agent
       within three business days after the expiration date.

     Upon request to the exchange agent, a notice of guaranteed delivery will be
sent to holders who wish to tender their existing notes according to the
guaranteed delivery procedures described above.

WITHDRAWAL OF TENDERS

     Except as otherwise provided in this prospectus, tenders of existing notes
may be withdrawn at any time prior to 5:00 p.m., New York City time, on the
expiration date.

     To withdraw a tender of existing notes in the exchange offer, a written or
facsimile transmission notice of withdrawal must be received by the exchange
agent at its address listed below prior to 5:00 p.m., New York City time, on the
expiration date. Any notice of withdrawal must:

     - specify the name of the person having deposited the existing notes to be
       withdrawn (the "depositor");

     - identify the existing notes to be withdrawn (including the certificate
       number or numbers and principal amount of the existing notes or, in the
       case of existing notes transferred by book-entry transfer, the name and
       number of the account at the depositary to be credited);

     - be signed by the depositor in the same manner as the original signature
       on the letter of transmittal by which the existing notes were tendered
       (including any required signature guarantee) or be accompanied by
       documents of transfer sufficient to permit the trustee for the existing
       notes to register the transfer of the existing notes into the name of the
       depositor withdrawing the tender; and

     - specify the name in which any of these existing notes are to be
       registered, if different from that of the depositor.

     All questions as to the validity, form and eligibility (including time of
receipt) of the withdrawal notices will be determined by us, whose determination
shall be final and binding on all parties. Any existing notes so withdrawn will
be judged not to have been tendered according to the procedures in this
prospectus for purposes of the exchange offer, and no exchange notes will be
issued in exchange for those
                                       26
<PAGE>   33

existing notes unless the existing notes so withdrawn are validly retendered.
Any existing notes that have been tendered but are not accepted for exchange
will be returned to the holder of the existing notes without cost to the holder
as soon as practicable after withdrawal, rejection of tender or termination of
the exchange offer. Properly withdrawn existing notes may be retendered by
following one of the procedures described above under "-- Procedures for
Tendering" at any time prior to the Expiration Date.

       notes; and

     - no judicial or administrative proceeding shall have been threatened that
       would limit us from proceeding with the exchange offer.

SOLICITATION OF TENDERS; FEES AND EXPENSES

     We will bear the expenses of requesting that holders of existing notes
tender those notes for exchange notes. The principal solicitation under the
exchange offer is being made by mail. Additional solicitations may be made by
our officers and regular employees and our affiliates in person, by telegraph,
telephone or telecopier.

     We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to brokers, dealers or other persons
soliciting acceptances of the exchange offer. We, however, will pay the exchange
agent reasonable and customary fees for its services and will reimburse the
exchange agent for its reasonable out-of-pocket costs and expenses in connection
with the exchange offer and will indemnify the exchange agent for all losses and
claims incurred by it as a result of the exchange
                                       27
<PAGE>   34

offer. We may also pay brokerage houses and other custodians, nominees and
fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding
copies of this prospectus, letters of transmittal and related documents to the
beneficial owners of the existing notes and in handling or forwarding tenders
for exchange.

     We will pay the expenses to be incurred in connection with the exchange
offer, including fees and expenses of the exchange agent and trustee and
accounting and legal fees and printing costs.

     You will not be obligated to pay any transfer tax in connection with the
exchange, except if you instruct us to register new notes in the name of, or
request that notes not tendered or not accepted in the exchange offer be
returned to, a person other than you, you will be responsible for the payment of
any applicable transfer tax.

ACCOUNTING TREATMENT

     The exchange notes will be recorded at the same carrying value as the
existing notes, as reflected in our accounting records on the date of the
exchange. Accordingly, no gain or loss for accounting purposes will be
recognized by us upon the closing of the exchange offer. We will amortize the
expenses of the exchange offer over the term of the exchange notes.

FEDERAL INCOME TAX CONSEQUENCES

     This general discussion of United States federal income tax consequences
applies to you if you are a United States holder, you acquired existing notes at
original issue for cash and you exchange those existing notes for exchange notes
in the exchange offer. This discussion only applies to you if you purchased
existing notes in the exchange offer for an amount equal to the "issue price" of
the notes and hold the exchange notes as a "capital asset," generally, for
investment, under Section 1221 of the Internal Revenue Code. This summary,
however, does not consider state, local or foreign tax laws. In addition, it
does not include all of the rules which may affect the United States tax
treatment of your investment in the exchange notes. For example, special rules
not discussed here may apply to you if you are, including without limitation:

     - a broker-dealer, a dealer in securities or a financial institution;

     - an insurance company;

     - a tax-exempt organization;

     - holding the exchange notes through partnerships or other pass-through
       entities; or

     - holding the exchange notes as part of a hedge, straddle or other risk
       reduction or constructive sale transaction.

     This discussion only represents our best attempt to describe some federal
income tax consequences that may apply to you based on current United States
federal tax law. This discussion may in the end inaccurately describe the
federal income tax consequences which are applicable to you because the law may
change, possibly retroactively, and because the IRS or any court may disagree
with this discussion.

     This summary may not cover your particular circumstances because it does
not consider foreign, state or local tax rules, disregards federal tax rules,
and does not describe future changes in federal tax rules. Please consult your
tax advisor concerning the application of United States federal income tax laws,
as well as the laws of any state, local or foreign taxing jurisdiction, to your
particular situation rather than relying on this general description.

                                       28
<PAGE>   35

UNITED STATES HOLDER

     You are a United States holder if you hold notes and you are:

     - a citizen or resident of the United States;

     - a corporation or partnership created or organized in the United States or
       under the laws of the United States or of any political subdivision;

     - an estate the income of which is subject to United States federal income
       tax regardless of its source; or

     - a trust, if (1) a United States court can exercise primary supervision
       over the administration of the trust and one or more United States
       persons can control all substantial decisions of the trust, or (2) the
       trust was in existence on August 20, 1996 and has properly elected to
       continue to be treated as a United States person.

RECEIPT OF EXCHANGE NOTES

     Because the economic terms of the exchange notes and the existing notes are
identical, your exchange of existing notes for exchange notes under the exchange
offer will not constitute a taxable exchange of the existing notes. As a result:

     - you will not recognize taxable gain or loss when you receive exchange
       notes in exchange for existing notes;

     - your holding period in the exchange notes will include your holding
       period in the existing notes; and

     - your basis in the exchange notes will equal your basis in the existing
       notes.

SALE OR OTHER TAXABLE DISPOSITION OF EXCHANGE NOTES

     You must recognize taxable gain or loss on the sale, exchange, redemption,
retirement or other taxable disposition of an exchange note. The amount of your
gain or loss equals the difference between the amount you receive for the
exchange note in cash or other property, valued at fair market value, minus the
amount attributable to accrued qualified stated interest on the exchange note,
minus your adjusted tax basis in the exchange note. Your initial tax basis in an
exchange note equals the price you paid for the existing note which you
exchanged for the exchange note increased by amounts previously includable in
income as original issue discount and reduced by any payments other than
payments of qualified stated interest made on the notes.

     Your gain or loss will generally be a long-term capital gain or loss if
your holding period in the exchange note is more than one year. Otherwise, it
will be a short-term capital gain or loss. Payments attributable to accrued
qualified stated interest which you have not yet included in income will be
taxed as ordinary interest income.

BACKUP WITHHOLDING

     You may be subject to a 31% backup withholding tax on payments of interest,
principal and premium on, and any proceeds upon the sale or disposition of, an
exchange note. Some holders, including, among others, corporations and some
tax-exempt organizations, are generally not subject to backup withholding. In
addition, the 31% backup withholding tax will not apply to you if you provide
your taxpayer identification number in the prescribed manner unless:

     - the IRS notifies us or our agent that the taxpayer identification number
       you provided is incorrect;

     - you fail to report interest and dividend payments that you receive on
       your tax return and the IRS notifies us or our agent that withholding is
       required; or

     - you fail to certify under penalties of perjury that you are not subject
       to backup withholding.

                                       29
<PAGE>   36

     You should consult your tax advisor as to your qualification for exemption
from backup withholding and the procedure for obtaining an exemption. If the 31%
backup withholding tax does apply to you, you may use the amounts withheld as a
refund or credit against your federal income tax liability as long as you
provide necessary information to the IRS.

PARTICIPATION IN THE EXCHANGE OFFER; UNTENDERED NOTES

     Participation in the exchange offer is voluntary. Holders of the existing
notes are urged to consult their financial and tax advisors in making their own
decisions on what action to take.

     As a result of the making of, and upon acceptance for exchange of all
existing notes tendered under the terms of, this exchange offer, we will have
fulfilled a covenant contained in the terms of the registration rights
agreement. Holders of the existing notes who do not tender their certificates in
the exchange offer will continue to hold the certificates and will be entitled
to all the rights, and subject to the limitations applicable to the existing
notes, under the indenture, except for any rights under the registration rights
agreement that by their term terminate or cease to have further effect as a
result of the making of this exchange offer. See "Description of the Notes." All
untendered existing notes will continue to be subject to the restrictions on
transfer described in the indenture. To the extent that existing notes are
tendered and accepted in the exchange offer, the trading market for untendered
existing notes could be adversely affected. This is because there will probably
be many fewer remaining existing notes outstanding following the exchange,
significantly reducing the liquidity of the untendered notes.

     We may in the future seek to acquire untendered existing notes in the open
market or through privately negotiated transactions, through subsequent exchange
offers or otherwise. We intend to make any acquisitions of existing notes
following the applicable requirements of the Exchange Act, and the rules and
regulations of the Commission under the Exchange Act, including Rule 14e-1, to
the extent applicable. We have no present plan to acquire any existing notes
that are not tendered in the exchange offer or to file a registration statement
to permit resales of any existing notes that are not tendered in the exchange
offer.

                                  THE COMPANY

     We believe we are the largest company in the United States focused
primarily on the plumbing and mechanical contracting services industry. On April
1, 1999, we combined the operations of the ten founding companies, which
individually are leading regional providers of plumbing and mechanical
contracting services, and commenced operations as one company. We believe that
by combining these regional leaders into one professional organization, we have
created a national provider which we expect to strengthen and broaden our
relationships with our consolidating customer base and enhance our operating
efficiency. The ten founding companies have been in business for an average of
approximately 31 years and, in 1998 performed plumbing and mechanical
contracting services in 24 states. On a pro forma basis for the fiscal year
ended December 31, 1998, we generated revenues and EBITDA of $322.2 million and

                       SELECTED HISTORICAL FINANCIAL DATA

     AMPAM acquired the founding companies simultaneously on April 1, 1999. For
financial statement presentation purposes, Christianson has been identified as
the "accounting acquirer." As the accounting acquiror, for accounting purposes
under SEC SAB No. 97, Christianson is treated as

          - having acquired all the other founding companies (even though AMPAM
     legally made these acquisitions),

          - having merged with AMPAM (with purchase accounting reflected for
     AMPAM's non-management stock ownership) and

          - representing the financial history of AMPAM prior to April 1, 1999.

The following selected historical financial data for Christianson (not combined
or pro forma for the acquisition of the founding companies) as of December 31,
1997 and 1998 and August 31, 1996, and for the years ended August 31, 1995 and
1996, the four-month period ended December 31, 1996 and the years ended December
31, 1997 and 1998 and for the three months ended March 31, 1999, have been
derived from the audited financial statements of Christianson included elsewhere
in this Prospectus and reflect all adjustments, consisting of normal recurring
adjustments, necessary for a fair presentation of such data. The selected
historical financial data as of March 31, 1999 and for the three months ended
March 31, 1998, and as of August 31, 1993, 1994 and 1995 and for the years ended
August 31, 1993 and 1994, have been derived from the unaudited financial
statements of Christianson and, in the opinion of the Company management,
reflect all adjustments consisting of normal recurring adjustments necessary for
a fair presentation of such data. The results of operations for the three months
ended March 31, 1999 should not be regarded as indicative of the results that
may be expected for the full year.

(a)  The loss from operations and the level of net income in historical periods
     is primarily attributable to the level of owner's compensation paid during
     those periods.

(b)  For the purpose of this calculation "earnings" represents income from
     operations before income tax expense, plus fixed charges. "Fixed charges"
     consist of interest, whether expensed or capitalized, amortization of debt
     expense and an estimated portion of rentals representing interest expense.
     As a result of the loss incurred for the four months ended December 31,
     1996, earnings were insufficient to cover fixed charges by $1.4 million in
     that period.

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

INTRODUCTION

     The following discussion should be read in conjunction with the Unaudited
Pro Forma Combined Financial Statements and the founding companies' Financial
Statements and related notes thereto and "Selected Historical Financial Data"
appearing elsewhere in this prospectus.

     We believe we are the largest company in the United States focused
primarily on the plumbing and mechanical contracting services industry. On April
1, 1999, we combined the operations of the ten founding companies, which
individually are leading regional providers of plumbing and mechanical
contracting services, and commenced operations as one company. AMPAM's revenues
are derived primarily from plumbing and mechanical contracting services provided
to residential, commercial and institutional customers. Revenues from
construction contracts are generally accounted for on a percentage-
of-completion basis. Maintenance and repair revenues are recognized as the
services are performed. Of AMPAM's 1998 pro forma revenues, approximately 54%
were derived from residential services and approximately 46% were derived from
commercial and institutional services. Costs and estimated earnings in excess of
billings on uncompleted contracts are recorded as an asset and billings in
excess of costs and estimated earnings on uncompleted contracts are recorded as
a liability on the balance sheet. Provisions for estimated losses on uncompleted
contracts are made in the period in which the losses are determined. Changes in
job performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income, and their effects are
recognized in the period in which the revisions are determined.

     Cost of revenues consists primarily of salaries and benefits of employees
and materials, which represented approximately 28% and 51% of pro forma cost of
revenues in 1998 respectively, as well as, subcontracted services, depreciation,
fuel and other vehicle expenses and equipment rentals. A number of the founding
companies also include salaries of estimators, insurance and other indirect
costs in the cost of revenues. AMPAM's gross margin, which is gross profit
expressed as a percentage of revenues, depends on the relative proportions of
costs related to labor and materials. On projects in which a higher percentage
of the cost of revenues consists of labor costs, AMPAM typically achieves higher
gross margins than on projects in which materials represent more of the cost of
revenues. Selling, general and administrative expenses consist primarily of
compensation and related benefits for owners, management and administrative
salaries and benefits, insurance, advertising, office rent and utilities,
communications and professional fees. In connection with the acquisitions, some
owners and some key employees of the founding companies agreed to reductions in
their compensation and related benefits that would have totaled $14.7 million
for the 1998 fiscal year. Such reductions in salaries, bonuses and benefits have
been reflected as a pro forma adjustment in the Unaudited Pro Forma Combined
Statement of Operations and are reflected in the terms of employment agreements
with AMPAM. See "Unaudited Pro Forma Combined Financial Statements" and the
Notes thereto.

     AMPAM believes that it will realize savings from:

     - greater volume discounts from suppliers of materials, parts and supplies;

     - lower labor costs resulting from scheduling efficiencies and reduced down
       time;

     - increased use of off-site prefabricated components; and

     - increased use of technology.

Offsetting these savings will be costs related to AMPAM's new corporate
management, costs of being a reporting company and costs of integrating the
companies acquired in the acquisitions. See "Business -- Operating Strategy."

     The plumbing and mechanical contracting services industry is influenced by
seasonal factors, which generally result in lower activity levels during colder
winter months than other periods. As a result,
                                       38
<PAGE>   45

AMPAM expects that its revenues and results of operations will generally be
lower in the first and fourth quarters of each fiscal year, and higher in the
second and third quarters. See "Risk Factors -- Our industry experiences upturns
and downturns, depending on the season of the year and this could have an
adverse effect on our quarterly operating results."

     The acquisition of the founding companies has been accounted for using the
purchase method of accounting, and the total purchase price has been allocated
to the assets and liabilities of the companies acquired based upon the fair
values of the assets and liabilities. As a result, we will have significant non-
cash charges for depreciation and amortization expense related to the fixed
assets and "goodwill" that were acquired in the acquisition. Our balance sheet
includes an amount designated as "goodwill" that on a pro forma basis at March
31, 1999 was $107.8 million, representing 51% of assets and 609% of
stockholders' equity. In addition, we may pay additional consideration in the
form of cash and stock in the event that adjusted net income of the founding
companies for the year ended December 31, 1999 exceeds targeted levels. Any
payments of this type would result in additional "goodwill." Our balance sheet
and earnings will be similarly impacted by future acquisitions.

     In addition to the goodwill amortization issue described above, members of
management and founders received stock and/or stock options in connection with
the organization of AMPAM. The applicable accounting rules require that the
stock issued to some members of our management be treated as compensation
expense. As a result of this treatment, we recorded a non-recurring, non-cash
charge on April 1, 1999 of approximately $7.7 million which will reduce our
EBITDA and net income and will be reflected in our second quarter results. See
"Unaudited Pro Forma Combined Financial Statements" and the Notes thereto.

SUPPLEMENTAL UNAUDITED COMBINED FINANCIAL INFORMATION

     To facilitate a meaningful comparison, the following discussion and
analysis is based on the combined historical results of the founding companies.
The following supplemental unaudited combined financial information for the
periods presented do not purport to present those of the combined founding
companies in accordance with generally accepted accounting principles, which do
not allow for the aggregating of financial data for entities that are not under
common ownership. The following discussion represents merely a summation of the
revenues, cost of revenues (including depreciation), gross profit, selling,
general and administrative expenses and income from operations of the individual
founding companies on a historical basis and excludes the effects of the pro
forma adjustments that are included in the Unaudited Pro Forma Combined
Statements appearing elsewhere in this prospectus. Selling, general and
administrative expenses for periods prior to the acquisitions reflect the
effects of historical salary and distributions to the owners of the founding
companies. The data will not be comparable to, and may not be indicative of,
AMPAM's post-combination results of operations because:

     - the founding companies were not under common control or management and
       some founding companies had different tax structures (generally, S
       corporations) during the periods presented;

     - AMPAM will use the purchase method to establish a new basis of accounting
       to record the acquisitions;

     - AMPAM will incur incremental costs for its corporate management and the
       costs of being a public company;

     - the combined data do not reflect reductions in salary, bonus and benefits
       of the owners of the founding companies occurring in connection with the
       acquisitions; and

     - the combined data do not reflect the potential benefits and cost savings
       AMPAM expects to realize when operating as a combined entity.

     Nevertheless, management believes that the aggregate financial information
shown below is helpful in understanding the past operations of the founding
companies.

(a) The fiscal years presented are the years ended December 31, 1996, 1997 and
    1998, for all founding companies, except for Croson Ohio, Sherwood and
    Miller, for which the fiscal years presented are the years ended September
    30, 1996, 1997 and 1998 Nelson, for which the fiscal years presented are
    April 30, 1997, December 31, 1997 and 1998 and Christianson for which the
    fiscal years presented are August 31, 1996, December 31, 1997 and 1998. For
    the three months ended December 31, 1998, Croson Ohio, Sherwood and Miller
    had combined revenues of $16,329 and income from operations of $2,146.

(b) Because the 1996 information includes some unaudited 1996 data you are
    cautioned not to place undue reliance on this information. Nevertheless,
    management believes that this information may be helpful in understanding
    the past operations of the founding companies.

  Three months ended March 31, 1999 compared to the three months ended March 31,
1998

     Revenues increased approximately $17.1 million, or 24%, from $70.9 million
for the three months ended March 31, 1998 to $88.0 million for the three months
ended March 31, 1999. The increase in combined revenues occurred primarily at
RCR, Croson Ohio and Christianson. RCR's revenues increased $6.2 million, or
47%, from the three months ended March 31, 1998 to the three months ended March
31, 1999, primarily as a result of continued growth at the Canoga Park,
California and Las Vegas, Nevada locations. Croson Ohio's revenues increased
$4.9 million, or 39%, from the three months ended March 31, 1998 to the three
months ended March 31, 1999, primarily as a result of an increase in projects.
Christianson's revenues increased $4.1 million, or 32%, from the three months
ended March 31, 1998 to the three months ended March 31, 1999, primarily as a
result of the favorable housing market in Austin and the surrounding areas.

     Gross profit increased $6.6 million, or 44%, from $14.7 million for the
three months ended March 31, 1998 to $21.3 for the three months ended March 31,
1999. The increase in combined gross profit occurred primarily due to increases
in gross profit of $1.7 million, or 46%, at Christianson, $1.6 million, or 66%,
at RCR, $1.3 million, or 87%, at Croson Florida, and $1.3 million, or 389%, at
Power. The increase is primarily a result of the increased revenues and
increased gross margins of each of these companies. Combined gross margin
increased from 21% in the first three months of 1998 to 24% in the first three
months of 1999. Power's gross margin increased to 28% for the first three months
of 1999 from 9% for the first three months of 1998, primarily as a result of
improvements in the bidding environment. Croson Florida's, Christianson's, and
RCR's gross margins increased from 24%, 29%, and 19%, respectively, in the first
three months of 1998 to 34%, 32%, and 21%, respectively, in the first three
months of 1999, primarily due to increased prices resulting from the increased
demand for the companies' services.

                                       40
<PAGE>   47

     Combined selling, general and administrative expenses remained constant at
$10.2 million for the three months ended March 31, 1998 and 1999.

  Fiscal year ended December 31, 1998 compared to fiscal year ended December 31,
1997

     Combined revenues increased approximately $54.7 million, or 20%, from
$267.5 million for the 1997 fiscal year to $322.2 million for the 1998 fiscal
year. The increase in combined revenues occurred primarily at RCR, Christianson,
Croson Florida and Teepe's. RCR's revenues increased $13.6 million, or 27%, from
$49.7 million for the 1997 fiscal year to $63.3 million for the 1998 fiscal
year, primarily as a result of an increase in the number and size of projects
and contracts, reflecting the growth from two new facilities in Canoga Park,
California and Las Vegas, Nevada. Christianson's revenues increased $12.5
million, or 24.5%, from $50.9 million for the 1997 fiscal year to $63.4 million
for the 1998 fiscal year, primarily as a result of increased market share, more
favorable contract pricing and increased construction activity in the Austin and
central Texas housing market. Croson Florida's revenues increased $10.0 million,
or 56%, from $18.1 million for the 1997 fiscal year to $28.1 million for the
1998 fiscal year, primarily due to expanded operations and contract volumes at
Croson Florida's facility in the Tampa/Fort Meyers, Florida area. Teepe's
revenues increased $7.9 million, or 19%, from $42.7 million for the 1997 fiscal
year to $50.6 million for the 1998 fiscal year, primarily as a result of an
increase in large commercial construction contracts in the Columbus, Ohio area
as well as continued growth in governmental and institutional projects. The most
significant increase in revenues among the other founding companies was an
increase of $4.8 million, or 16%, which occurred at Keith Riggs, primarily as a
result of increased demand for services due to increased housing starts and also
due to increased maintenance revenues.

     Combined gross profit increased $18.2 million, or 38%, from $48.5 million
for the 1997 fiscal year to $66.7 million for the 1998 fiscal year, generally as
a result of increased market share, more favorable pricing and increased
construction activity in AMPAM's markets. The increase in combined gross profit
occurred primarily due to increases in gross profit of $4.3 million, or 32%, at
Christianson, $4.3 million, or 59%, at RCR, and $3.5 million, or 83%, at Croson
Florida. The increase in combined gross profit is primarily attributable to
increased revenues and increased margins of each of these companies. Combined
gross margin increased to 21% for the 1998 fiscal year from 18% for the 1997
fiscal year. Christianson's gross margin increased to 28% for the 1998 fiscal
year from 26% for the 1997 fiscal year, primarily as a result of small price
increases for new home construction and increased maintenance revenues. RCR's
gross margin increased to 18% for the 1998 fiscal year from 15% for the 1997
fiscal year, primarily due to improved pricing on many contracts as a result of
increased demand for RCR's services as well as due to efficiencies gained
through additional experience in the Canoga Park, California and Las Vegas,
Nevada markets. Croson Florida's gross margin increased to 27% for the 1998
fiscal year from 23% for the 1997 fiscal year, primarily as a result of
favorable pricing of its contracts in the Tampa/Fort Meyers, Florida area.

     Selling, general and administrative expenses increased $10.4 million, or
29%, from $35.6 million for the 1997 fiscal year to $46.0 million for the 1998
fiscal year. This increase occurred primarily due to an increase in selling,
general and administrative expenses of $5.6 million at Christianson and $2.7
million at RCR. The increase in Christianson's selling, general and
administrative expenses was primarily attributable to an increase in officer
compensation and to increases in administrative costs due to the increased
volume of contracts. RCR's increase was primarily attributable to an increase in
administrative support required by the increased revenues.

  Fiscal year ended December 31, 1997 compared to fiscal year ended December 31,
1996

     Revenues increased approximately $30.9 million, or 13%, from $236.6 million
for the 1996 fiscal year to $267.5 million for the 1997 fiscal year. The
increase in combined revenues occurred primarily at RCR, Teepe's and Croson
Florida. RCR's revenues increased $9.3 million, or 23%, from 1996 to 1997,
primarily as a result of the opening of two new facilities in early 1997.
Teepe's revenues increased $7.3 million, or 21%, from 1996 to 1997, primarily as
a result of an increase in large commercial construction contracts serviced from
Teepe's new facility in Columbus, Ohio which opened in August of 1997. Croson
Florida's
                                       41
<PAGE>   48

revenues increased $6.4 million, or 54%, from 1996 to 1997, primarily as a
result of an increase in the number and size of contracts and revenues from a
new facility in Tampa/Fort Meyers, Florida. All of the remaining seven founding
companies reported an increase between the 1997 and 1996 fiscal year, except for
Miller, which reported a decrease of $2.6 million, due to the fact that in 1997
Miller ceased to provide HVAC services which it had begun providing to a major
customer in 1996.

     Gross profit increased $7.9 million, or 19%, from $40.6 million for the
1996 fiscal year, to $48.5 million for the 1997 fiscal year. The increase in
combined gross profit occurred primarily due to increases in gross profit of
$2.0 million, or 38%, at RCR, $1.8 million, or 73%, at Croson Florida and $1.3
million, or 11%, at Christianson. The increase in combined gross profit is
primarily attributable to increased revenues and increased gross margins of each
of these companies. Combined gross margin increased slightly from 17% during the
1996 fiscal year to 18% during the 1997 fiscal year. RCR's gross margin
increased to 15% for the 1997 fiscal year from 13% for the 1996 fiscal year.
Croson Florida's gross margin increased to 23% during the 1997 fiscal year from
21% during the 1996 fiscal year, primarily as a result of Croson Florida's new
facility in the Tampa/Fort Meyers, Florida market and favorable overall pricing
of contracts. Christianson's gross margin increased to 26% for the 1997 fiscal
year from 24% for the 1996 fiscal year, primarily due to continued discounts on
materials purchases and incentive compensation programs.

     Selling, general and administrative expenses increased $5.9 million, or
20%, from $29.7 million in the 1996 fiscal year to $35.6 million in the 1997
fiscal year, generally from increased contract volumes and opening of new
facilities. This increase occurred primarily due to an increase in selling,
general and administrative expenses of $1.7 million at RCR, $1.1 million at
Croson Florida and $0.7 million at Teepe's. The increase in RCR's selling,
general and administrative expenses was primarily attributable to an increase in
administrative support required by the increased contract volume and costs
related to two start-up divisions. Croson Florida's increase was attributable to
the opening of a new facility in Tampa/ Fort Meyers, Florida, which includes
increases in administrative salaries and additional rent and travel expenses.
Teepe's increase was primarily attributable to an increase in administrative
support required by the increased revenues and one-time start-up costs
associated with the opening of Teepe's facility in Columbus, Ohio.

LIQUIDITY AND CAPITAL RESOURCES

     On a pro forma basis as adjusted for the original issuance of the notes, as
of March 31, 1999, AMPAM would have had approximately $30.9 million of working
capital, and $125.5 million of outstanding indebtedness including capital lease
obligations totaling $3.1 million.

     On a historical combined basis, the founding companies generated $8.3
million of cash from operating activities for the three months ended March 31,
1999, which includes owners compensation payments of $0.5 million in excess of
the payments to be made to the owners in accordance with their respective
employment agreements. Net cash provided by investing activities for the three
months ended March 31, 1999, was $2.2 million on a combined basis and was
primarily proceeds from sales of property and equipment. Net cash used in
financing activities for the three months ended March 31, 1999, was $6.6 million
on a combined basis and was primarily used for debt repayment and capital
distributions.

     On April 1, 1999, AMPAM entered into a credit facility with The First
National Bank of Chicago. The total commitment under the credit facility is $95
million, of which AMPAM drew approximately $70.3 million at the closing of the
acquisitions to fund a portion of the cash portion of acquisition consideration.
All of these amounts were repaid with proceeds of the original issuance of the
notes, leaving the full commitment of the credit facility available for
borrowings after closing subject to the borrowing conditions set forth in the
credit facility. See "Description of Other Indebtedness."

     On April 1, 1999, AMPAM also entered into a subordinated loan with Fleet
Corporate Finance, Inc. The total commitment under the subordinated loan is
approximately $30 million, all of which was drawn at closing. AMPAM used all of
this amount to fund a part of the cash portion of the acquisition

                                       42
<PAGE>   49

consideration. The entire amount of the subordinated loan was repaid with the
proceeds of the original issuance of the notes.

     AMPAM anticipates that its cash flow from operations will provide
sufficient cash to enable AMPAM to meet its working capital needs, debt service
requirements and planned capital expenditures for property and equipment through
the foreseeable future. Combined capital expenditures for the founding companies
for the 1998 fiscal year were $2.8 million.

     AMPAM intends to continue pursuing attractive acquisition opportunities. We
currently intend to acquire companies for a mix of stock and cash. The timing,
size or success of any acquisition effort and the associated potential capital
commitments cannot be predicted. AMPAM expects to fund future acquisitions
primarily with working capital, cash flow from operations and borrowings,
including any unborrowed portion of the credit facility, as well as issuances of
additional equity.

     Due to the relatively low levels of inflation experienced in the 1996, 1997
and 1998 fiscal years, inflation did not have a significant effect on the
results of the combined founding companies in those fiscal years, or on any of
the founding companies, individually.

  Three months ended March 31, 1999 compared to the three months ended March 31,
  1998

     Revenues increased $4.1 million, or 32%, from $12.7 million for the three
months ended March 31, 1998 to $16.8 million for the three months ended March
31, 1999, primarily due to price increases for new home construction contracts
and increases in the number of construction contracts resulting from the
favorable housing market in Austin and surrounding areas.

     Gross profit increased $1.7 million, or 46%, during the three months ended
March 31, 1999 to $5.4 million, and gross margin increased to 32% in the first
three months of 1999 from 29% in the first three months of 1998 as a result of
price increases for new home construction contracts and increased maintenance
and service revenues.

     Selling, general and administrative expenses decreased $1.4 million, or
43%, from $3.3 million for the three months ended March 31, 1998 to $1.9 million
for the three months ended March 31, 1999. The decrease was a result of a
decrease in officer compensation, offset by an increase in overhead related to
the overall growth in the business. The total officers' compensation for the
three months ended March 31, 1999 was $0.4 million compared to $2.1 million for
the three months ended March 31, 1998 due to agreed upon compensation
reductions.

  Year ended December 31, 1998 compared to the year ended December 31, 1997

     Revenues increased $12.5 million, or 25%, from $50.9 million for the year
ended December 31, 1997 to $63.4 million for the year ended December 31, 1998,
primarily due to increased market share as a result of contracts with new
builder customers, small increases in contract pricing and increased
construction activity in the Austin and central Texas housing market.

     Gross profit increased $4.3 million, or 32%, during the year ended December
31, 1998 to $17.7 million, and gross margin increased to 28% in 1998 from 26% in
1997 as a result of small increases in contract pricing and increased
maintenance and service revenues.

     Selling, general and administrative expenses increased $5.6 million, or
49%, from $11.5 million for the year ended December 31, 1997 to $17.1 million
for the year ended December 31, 1998. The increase was attributable to an
increase in officer compensation and increases in administrative costs due to
the increased volume of contracts. The total officers' compensation for the year
ended December 31, 1998 was $10.7 million.

  Year ended December 31, 1997 compared to the year ended August 31, 1996

     Revenues increased $0.6 million, or 1%, from $50.3 million for the year
ended August 31, 1996 to $50.9 million for the 1997 fiscal year, primarily as a
result of increased construction activity in Christianson's areas of operations.

     Gross profit increased $1.3 million, or 11%, during the 1997 fiscal year to
$13.4 million, and gross margin increased to 26% during the 1997 fiscal year
from 24% during the 1996 fiscal year as a result of continued discounts on
materials purchases and incentive compensation programs.

     Selling, general and administrative expenses increased $0.4 million, or 4%,
from $11.1 million for the 1996 fiscal year to $11.5 million for the 1997 fiscal
year. The increase was attributable to an increase in rent expenses and real
property taxes after Christianson's relocation to a new headquarters facility in
November 1997 offset by a $0.3 million reduction in total officers' compensation
for the year ended December 31, 1997 which was $6.6 million.

LIQUIDITY AND CAPITAL RESOURCES

     Christianson generated approximately $3.7 million of net cash from
operating activities for the three months ended March 31, 1999 primarily due to
net income before depreciation and deferred income taxes of $3.5 million and a
decrease in working capital of $0.2 million. Net cash used in investing
activities was approximately $0.1 million related to the purchase of property
and equipment. Net cash used in financing activities was approximately $0.1
million, primarily related to the repayment of long-term debt.

     At March 31, 1999, Christianson had working capital of $8.3 million and
total debt of $1.0 million.

     Christianson generated approximately $2.5 million of net cash from
operating activities for year ended December 31, 1998 primarily due to net
income before depreciation and deferred income taxes of $1.3 million and a
decrease in working capital of $1.2 million. Net cash used in investing
activities was approximately $0.2 million related to the purchase of property
and equipment. Net cash used in financing activities was approximately $0.5
million, primarily related to the repayment of long-term debt.

     Revenues increased $6.2 million, or 47%, from $13.2 million for the three
months ended March 31, 1998 to $19.4 million for the three months ended March
31, 1999, primarily as a result of continued growth generated by the two newer
facilities in Canoga Park, California and Las Vegas, Nevada.

     Gross profit increased $1.6 million, or 66%, during the three months ended
March 31, 1999 to $4.0 million, and gross margin increased to 21% in the first
three months of 1999 from 19% in the first three months of 1998 as a result of
increases in pricing on many contracts reflecting increased demand for RCR's
services and cost efficiencies achieved in the additional markets serviced by
the two newer facilities.

     Selling, general and administrative expenses increased $0.8 million, or
42%, from $1.7 million for the three months ended March 31, 1998 to $2.5 million
for the three months ended March 31, 1999. The increase was attributable to an
increase in administrative support related to the continued growth generated by
the newer facilities.

  Year ended December 31, 1998 compared to the year end December 31, 1997

     Revenues increased $13.6 million, or 27%, from $49.7 million for the year
ended December 31, 1997 to $63.3 million for the year ended December 31, 1998,
primarily as a result of an increase in the number and size of projects and
contracts, reflecting the growth from two new facilities in Canoga Park,
California and Las Vegas, Nevada.

     Gross profit increased $4.3 million, or 59%, during the year ended December
31, 1998 to $11.7 million, and gross margin increased to 18% in 1998 from 15% in
1997 as a result of improved pricing on many contracts as well as due to
efficiencies gained through additional experience in the Canoga Park and Las
Vegas markets.

     Selling, general and administrative expenses increased $2.7 million, or
47%, from $5.7 million for the December 31, 1997 to $8.4 million for the
December 31, 1998. The increase was attributable to an increase in
administrative support required by the increased contract volumes.

     Revenues increased $9.3 million, or 23%, from $40.4 million for the 1996
fiscal year to $49.7 million for the 1997 fiscal year, primarily as a result of
the opening of two new operating divisions in early 1997 in Canoga Park,
California and Las Vegas, Nevada.

     Gross profit increased $2.0 million, or 38%, during the 1997 fiscal year to
$7.4 million as a result of an increase in revenues for two new facilities in
Canoga Park, California and Las Vegas, Nevada and improvements in gross margin.
Gross margin increased slightly to 15% during the year ended December 31, 1997
from 13% during the 1996 fiscal year.

  Three months ended March 31, 1999 compared to the three months ended March 31,
1998

     Revenues decreased $0.9 million, or 8%, from $11.4 million for the three
months ended March 31, 1998 to $10.5 million for the three months ended March
31, 1999, primarily due to the fact that the majority of the projects in
progress during the first three months of 1999 were in the beginning stages, the
phase in which less revenues are earned.

     Gross profit decreased $0.1 million, or 9%, from $1.4 million during the
three months ended March 31, 1998 to $1.3 million during the three months ended
March 31, 1998, as a result of the decrease in revenues discussed above. Gross
margin remained constant for the three months ended March 31, 1998 and 1999 at
12%.

     Selling, general and administrative expenses decreased $0.1 million, or 7%,
from $1.2 million for the three months ended March 31, 1998 to $1.1 million for
the three months ended March 31, 1999. The decrease is a result of certain cost
reduction measures implemented by management coupled with the voluntary
termination of certain members of the office staff who have not been replaced.

  Year ended December 31, 1998 compared to the year ended December 31, 1997

     Revenues increased $7.9 million, or 19%, from $42.7 million for the year
ended December 31, 1997 to $50.6 million for the year ended December 31, 1998,
primarily as a result of an increase in large commercial construction contracts
in the Columbus, Ohio area as well as continued growth in governmental and
institutional projects.

     Gross profit increased $1.1 million, or 19%, from $5.5 million during the
year ended December 31, 1997 to $6.6 million during the year ended December 31,
1998, as a result of an increased number of successful bids with higher gross
margins and further expansion in the Columbus, Ohio market. Gross margin
remained constant for 1997 and 1998 at 13%.

     Selling, general and administrative expenses increased $0.6 million, or
15%, from $4.2 million for the year ended December 31, 1997 to $4.8 million for
the year ended December 31, 1998. The increase was attributable to an increase
in administrative support required by the higher level of revenues and due to
additional overhead associated with the opening of a new facility in the
Columbus, Ohio area.

 Year ended December 31, 1997 compared to the year ended December 31, 1996

     Revenues increased $7.3 million, or 21%, from $35.4 million for the 1996
fiscal year to $42.7 million for the 1997 fiscal year, primarily as a result of
an increase in large commercial construction contracts performed from a new
facility in Columbus, Ohio which opened in August of 1997.

     Gross profit increased $0.5 million, or 11%, from $5.0 million during the
1996 fiscal year to $5.5 million during the 1997 fiscal year, and gross margin
decreased to 13% during the 1997 fiscal year from 14% during the 1996 fiscal
year as a result of further efforts to expand into the Columbus, Ohio market.

     Selling, general and administrative expenses increased $0.7 million, or
22%, from $3.4 million for the 1996 fiscal year to $4.2 million for the 1997
fiscal year. The increase was attributable to an increase in administrative
support required by the increased contract volumes and one-time start-up costs
associated with the opening of a new facility in Columbus, Ohio.

months ended March 31, 1998 to $17.2 million for the six months ended March 31,
1999, primarily as a result of additional HVAC and plumbing projects.

     Gross profit increased $1.0 million, or 52%, from $1.8 million during the
six months ended March 31, 1998 to $2.8 million during the six months ended
March 31, 1999, and gross margin increased nominally to 16% in 1999 from 15% in
1998 as a result of increased prices, as well as cost efficiencies, for
wastewater treatment plant projects.

     Selling, general and administrative expenses increased $0.3 million, or 38%
from $0.9 million for the six months ended March 31, 1998 to $1.2 million for
the six months ended March 31, 1999, primarily as a result of an increase in
advertising and supply expense related to the combination of Croson Ohio's and
Teepe's operations as well as an increase in administrative salaries.

  Year ended September 30, 1998 compared to the year ended September 30, 1997

     Revenues decreased $1.8 million or 7%, from $27.0 million for the year
ended September 30, 1997 to $25.2 million for the year ended September 30, 1998,
primarily as a result of a decrease in new starts due to strong competition in
Ohio.

     Gross profit increased $0.7 million, or 18%, from $4.1 million during the
year ended September 30, 1997 to $4.8 million during the year ended September
30, 1998, and gross margin increased to 19% in 1998 from 15% in 1997 as a result

million for the year ended September 30, 1997 to $2.0 million for the year ended
September 30, 1998, primarily as a result of a decrease in administrative
salaries due to the retirement of a key employee. In addition, Croson Ohio
replaced the profit sharing plan with a discretionary bonus plan, which resulted
in less expense.

  Year ended September 30, 1997 compared to the year ended September 30, 1996

     Revenues increased $0.8 million, or 3%, from $26.2 million for the 1996
fiscal year to $27.0 million for the 1997 fiscal year, primarily as a result of
larger contracts for mechanical contracting services for wastewater and
purification projects, offset by smaller plumbing contracting services contracts
due to increased competition in the Columbus, Ohio area.

     Gross profit increased $0.2 million, or 5%, from $3.9 million during the
1996 fiscal year to $4.1 million during the 1997 fiscal year, as a result of
increased revenues. Gross margin remained relatively constant at 15% for the
1996 and 1997 fiscal years.

     Gross profit increased $1.3 million or, 87%, from $1.5 million during the
three months ended March 31, 1998 to $2.8 million during the three months ended
March 31, 1999, and gross margin increased to 34% in the first three months of
1999 from 24% in the first three months of 1998 as a result of price increases
reflecting the demand for Croson Florida's services and costs efficiencies
obtained from additional experience in the newer operation.

     Selling, general and administrative expenses increased $0.2 million, or
21%, from $0.7 million for the three months ended March 31, 1998 to $0.9 million
for the three months ended March 31, 1999. The increase was due to an increase
in compensation and an increase in the number of employees needed at the newer
Tampa/Fort Meyer facility.

</TABLE>

  Three months ended March 31, 1999 compared to the three months ended March 31,
  1998

     Revenues increased $2.1 million, or 61%, from $3.5 million for the three
months ended March 31, 1998 to $5.6 million for the three months ended March 31,
1999, primarily as a result of an increase in the demand for Power's services,
which has increased the volume of projects.

     Gross profit increased $1.3 million, or 389%, during the three months ended
March 31, 1999 to $1.6 million, and gross margin increased to 28% in the three
months ended March 31, 1999 from 9% in the three months ended March 31, 1998 as
a result of an improved bidding environment resulting from the increase in
demand and slightly lower materials costs. In addition, Power began achieving
cost efficiencies associated with gaining experience working with certain
builders with whom recurring work was performed and further cost reductions were
achieved as a result of Power's business being provided primarily in the Houston
area versus areas outside Houston.

     Selling, general and administrative expenses increased $0.1 million, or
59%, from $0.2 million for the three months ended March 31, 1998 to $0.3 million
for the three months ended March 31, 1999. The increase was attributable to a
slight increase in administrative payroll and payroll related costs as well as
an increase in communication costs and in travel and entertainment expenses.

  Year ended December 31, 1998 compared to the year ended December 31, 1997

     Revenues increased slightly by $0.1 million, or 1%, from $17.0 million for
the year ended December 31, 1997 to $17.1 million for the year ended December
31, 1998, primarily as a result of favorable market conditions in Houston,
offset by the limited capacity to accept additional work.

     Gross profit increased $0.4 million, or 18%, during the year ended December
31, 1998 to $2.7 million, and gross margin increased to 16% in the year ended
December 31, 1998 from 14% in the year ended December 31, 1997 as a result of a
decrease in material prices, partially offset by an increase in labor rates.

     Selling, general and administrative expenses increased $0.2 million, or
12%, from $1.1 million for the year ended December 31, 1997 to $1.3 million for
the year ended December 31, 1998. The increase was attributable to an increase
in administrative salary expense and increased employee benefits.

 Eleven months ended March 31, 1999 compared to the year ended April 30, 1998

     Revenues of $14.0 million were earned during the eleven months ended March
31, 1999 compared to $14.2 million earned during the year ended April 30, 1998.
Fiscal year 1999 revenues are on pace to exceed fiscal year 1998 revenues as a
result of the continued growth in underground utility installation and building
pipe replacement projects.

     Gross profit of $4.7 million was earned for the eleven months ended March
31, 1999 compared to $4.6 million earned during the year ended April 30, 1998.
Fiscal year 1999 gross profit is on pace to exceed fiscal year 1998 gross profit
as a result of material and labor cost efficiencies associated with building
pipe replacement contracts. Gross margin increased nominally to 33% in 1999 from
32%.

     Selling, general and administrative expenses were $1.9 million for the
eleven months ended March 31, 1999 compared to $2.5 million for the year ended
April 30, 1998, which would result in a decrease for the fiscal year. The
decrease is due to a reduction in officer compensation.

  Year ended April 30, 1998 compared to the year ended April 30, 1997

     Revenues increased $1.7 million, or 14%, from $12.5 million for the 1997
fiscal year to $14.2 million for the 1998 fiscal year, primarily as a result of
an increase in contracts for underground utility installation and existing
building pipe replacement, partially offset by the effects of the wet winter
season in the panhandle region of Florida.

     Gross profit increased $1.2 million, or 35%, during the year ended April
30, 1998 to $4.6 million, and gross margin increased to 32% during the 1998
fiscal year from 27%, during the 1997 fiscal year as a result of increased
margins on materials required for some building pipe replacement contracts, and
reduced labor costs associated with Nelson's underground utility contracts.

     Selling, general and administrative expenses increased $0.1 million, or 2%,
from $2.4 million for the 1997 fiscal year to $2.5 million for the 1998 fiscal
year. The increase was attributable to an increase in office labor expense.

  Six months ended March 31, 1999 compared to the six months ended March 31,
1998

     Revenues increased $1.1 million, or 16%, from $6.6 million for the six
months ended March 31, 1998 to $7.7 million for the six months ended March 31,
1999, primarily as a result of an increase in private projects, principally
hotels.

     Gross profit remained constant at $1.2 million for the three months ended
March 31, 1998 and 1999; however gross margin decreased to 16% in the six months
1999 from 19% in 1998 as a result of inefficiency for two specific projects due
to contract period extension.

     Selling, general and administrative expenses increased $0.3 million, or
40%, from $0.9 million for the six months ended March 31, 1998 to $1.2 million
for the six months ended March 31, 1999. The increase was attributable to
continued development of the pre-fab department, creation of a Special Projects
division, and expansion of the Design department.

  Year ended September 30, 1998 compared to the year ended September 30, 1997

     Revenues increased $2.1 million, or 18%, from $11.5 million for the year
ended September 30, 1997 to $13.6 million for the year ended September 30, 1998,
primarily as a result of the expansion into more on-site utility services, and
an increase in public works projects and private projects, principally hotels.

     Gross profit increased $0.9 million, or 54%, during 1998 to $2.5 million,
and gross margin increased to 18% in 1998 from 14% in 1997 as a result of
Sherwood's new prefabrication process and improved market conditions as well as
an increase in the number of private sector projects.

     Selling, general and administrative expenses increased $0.7 million, or
45%, from $1.5 million for the year ended September 30, 1997 to $2.2 million for
the year ended September 30, 1998. The increase was attributable to an increase
in costs related to the relocation to a new facility and an increase in staffing
necessary to manage growing operations. In addition, Sherwood incurred a one
time charge related to a litigation settlement of approximately $0.3 million.

  Six months ended March 31, 1999 compared to the six months ended March 31,
1998

     Revenues decreased $0.2 million, or 4%, from $5.4 million for the six
months ended March 31, 1998 to $5.2 million for the six months ended March 31,
1999, primarily as a result of a reduction in projects with a significant
customer.

     Gross profit increased $0.1 million, or 9%, from $1.7 million during the
six months ended March 31, 1998 to $1.8 million during the six months ended
March 31, 1999, and gross margin increased to 35% in the six months ended March
31, 1999 from 31% in the six months ended March 31, 1998 as a result of
favorable pricing and improved efficiencies resulting from experience obtained
in performing similar projects.

     Selling, general and administrative expenses decreased $0.3 million, or
27%, from $1.2 million for the six months ended March 31, 1998 to $0.9 million
for the six months ended March 31, 1999. The decrease was attributable to a
reduction in officer compensation.

  Year ended September 30, 1998 compared to the year ended September 30, 1997

     Revenues increased $3.3 million, or 41%, from $8.0 million for the year
ended September 30, 1997 to $11.3 million for the year ended September 30, 1998,
primarily as a result of an increase in multifamily housing starts and increased
contract volumes in Miller's areas of operations.

     Gross profit increased $1.4 million, or 64%, from $2.2 million during the
year ended September 30, 1997 to $3.7 million for the year ended September 30,
1998 as a result of the increase in revenues and gross margins. Gross margin
increased to 32% in 1998 from 28% in 1997 as a result of small increases in
contract pricing and increased productivity.

     Selling, general and administrative expenses increased $0.5 million, or
25%, from $2.0 million for the year ended September 30, 1997 to $2.5 million for
the year ended September 30, 1998. The increase was attributable to an increase
in officer and employee bonus compensation.

YEAR 2000

     Year 2000 Issue. Many software applications, hardware and equipment and
embedded chip systems identify dates using only the last two digits of the year.
These products may be unable to distinguish between dates in the year 2000 and
dates in the year 1900. That inability (referred to as the "Year 2000" issue),
if not addressed, could cause applications, equipment or systems to fail or
provide incorrect information after December 31, 1999, or when using dates after
December 31, 1999. This in turn could have an adverse effect on AMPAM due to
AMPAM's direct dependence on its own applications, equipment and systems and
indirect dependence on those of other entities with which AMPAM must interact.

     Risk of Non-Compliance and Contingency Plans. The major applications which
pose the greatest Year 2000 risks for AMPAM if implementation of the Year 2000
compliance program is not successful are AMPAM's project estimating and
management systems, and its financial systems applications, including related
third-party software. Potential problems if the Year 2000 compliance program is
not successful could include disruptions of AMPAM's revenue generation and
collection from its customers and purchasing and payments to its vendors and the
inability to perform its other financial and accounting functions. AMPAM
operates on a decentralized basis with each individual reporting unit having
independent information technology (IT) and non-IT systems. AMPAM's Year 2000
compliance program is focused on the systems which could materially affect its
business. AMPAM has completed a preliminary assessment of its significant
operating units and believes that the systems at these companies are or will
shortly be Year 2000 compliant. AMPAM currently has assessed its remaining Year
2000 risk as low because:

     - AMPAM is not dependent on any key customers or suppliers (none represent
       as much as 5% of AMPAM's sales or purchases, respectfully),

     - AMPAM has many separate PC based systems and is not dependent on any one
       system,

     - many of AMPAM's processes are performed using spreadsheets and/or other
       manual processes which are not technologically dependent,

     - AMPAM performs construction and service maintenance on site for its
       customers, the work performed is manual in nature and not dependent on
       automated information technology systems to be completed, and

     - AMPAM currently believes that most of its systems that have Year 2000
       compliance issues are based on prepackaged third-party software that can
       be upgraded at nominal costs through vendor supported upgrades.

     As a result, AMPAM believes that its reasonably likely worst case Year 2000
scenario is a temporary inability for it to process the accounting transactions
representing its business activity using automated information systems at some
of its operating units.

     The goal of AMPAM's year 2000 project is to ensure that all of the critical
systems and processes which are under the direct control of AMPAM remain
functional. However, because some systems and processes may be interrelated with
systems outside of the control of AMPAM, there can be no assurance that all
implementations will be successful. Accordingly, as part of the Year 2000
project, contingency and business plans are in the process of being developed to
respond to potential failures that may occur. Such contingency and business
plans are scheduled to be completed by the fourth quarter of fiscal 1999. To the
extent appropriate, these plans will include emergency back up and recovery
procedures, remediation of existing systems with system upgrades or installation
of new systems and replacing electronic applications with manual processes. Due
to the uncertain nature of contingency planning, there can be no assurances that
these plans actually will be sufficient to reduce the risk of material impacts
on AMPAM's operations due to Year 2000 issues. AMPAM has ongoing information
systems development and implementation projects, none of which have experienced
delays due to its Year 2000 compliance program.

     Compliance Program. In order to address the Year 2000 issue, AMPAM has
established a project team to assure that key automated systems and related
processes will remain functional through year 2000. The team is addressing the
project in the following stages: (1) awareness, (2) assessment, (3) remediation,
(4) testing and (5) implementation of the necessary modifications. The key
automated systems consist of (a) project estimating, management and financial
systems applications, (b) hardware and equipment, (c) embedded chip systems and
(d) third-party developed software. The evaluation of the Year 2000 issue
includes the evaluation of the Year 2000 exposure of third parties material to
the operations of AMPAM.

     AMPAM State of Readiness. The awareness phase of the Year 2000 project has
begun with a corporate-wide awareness program which will continue to be updated
throughout the life of the project. AMPAM believes that there is not a material
risk related to its non-IT systems because AMPAM is primarily a manual service
provider and does not rely on these types of systems. The assessment phase of
the project involves for both IT and non-IT systems, among other things, efforts
to obtain representations and assurances from third parties, including third
party vendors, that their hardware and equipment, embedded chip systems and
software being used by or impacting AMPAM or any of its business units are or
will be modified to by Year 2000 compliant. To date, AMPAM does not expect that
responses from third parties will be conclusive. However, because AMPAM is not
dependent on any key customers or suppliers, AMPAM does not believe that a
disruption in service with any third party would have a material adverse effect
on its business, results of operations or financial condition. The remediation
phase involves identifying the changes which are required to be implemented by
system for them to be Year 2000 compliant. The testing and implementation phases
involve verifying that the identified changes address the Year 2000 problems
identified through testing the system as part of implementing SUCH changes.
Management expects that the remediation, testing and implementation phases will
be substantially completed during the third and fourth quarters of fiscal 1999.

     Costs to Address Year 2000 Compliance Issues. While the total cost to AMPAM
of the Year 2000 project is still being evaluated, AMPAM's management currently
estimates that the costs to be incurred by AMPAM in 1999 associated with the
assessing and testing applications, hardware and equipment, embedded chip
systems, and third party developed software will be less than $500,000, which
will be funded with existing operating cash flows and AMPAM will deduct from
income as incurred. AMPAM believes that software vendor Year 2000 releases
should address the majority of AMPAM's Year 2000 issues. These costs were
primarily related to the assessment phase of the project. AMPAM expects that the
majority of its costs related to the Year 2000 project to be incurred in the
third and fourth quarters of its 1999 fiscal year. Because AMPAM's internal
systems are PC-based, management does not expect the costs to AMPAM of the Year
2000 project to have a material adverse effect on AMPAM's financial position,
results of operations or cash flows.

                                    BUSINESS

     We believe AMPAM is the largest company in the United States focused
primarily on the plumbing and mechanical contracting services industry. On April
1, 1999, AMPAM combined the operations of the ten founding companies, which
individually are leading regional providers of plumbing and mechanical
contracting services, and commenced operations as one company. AMPAM believes
that by combining these regional leaders into one professional organization,
AMPAM has created a national provider which it expects to strengthen and broaden
AMPAM's relationships with its consolidating customer base and enhance its
operating efficiency. The ten founding companies have been in business for an
average of approximately 31 years and, in 1998 performed plumbing and mechanical
contracting services in 24 states. On a pro forma basis for the fiscal year
ended December 31, 1998, AMPAM generated revenue and EBITDA of $322.2 million
and $39.6 million, respectively.

     Plumbing contracting includes the installation of integrated domestic water
systems, sanitary waste and vent systems, irrigation systems, fire protection
systems and natural gas piping systems. Mechanical contracting includes the
installation of mechanical and process piping and tubing systems that convey hot
and chilled water, steam, medical gases, fuels and other liquid and gaseous
substances. Both plumbing and mechanical systems include related equipment
(water heaters, boilers, chillers, pumps, sprinklers and drains) and fixtures
(basins, toilets, sinks, tubs, faucets, spigots and valves). AMPAM also provides
renovation/retrofitting and maintenance and repair services for plumbing and
mechanical systems on a per-visit basis and under short-term and long-term
maintenance contracts.

     AMPAM provides plumbing and mechanical contracting services in the
residential and commercial/ institutional markets. The residential market
includes single family and multifamily homes and low-rise apartments. The
commercial/institutional market includes retail establishments, office
buildings, high-rise apartments and condominiums, theaters and restaurants,
hotels and casinos, waste water and water purification plants, manufacturing
plants and other industrial complexes, and public and private institutional
buildings, including schools, hospitals, dormitories, assisted-living centers,
military and other governmental facilities, stadiums, arenas, convention
centers, airports and prisons. During fiscal 1998, approximately 54%, and 46% of
AMPAM's pro forma revenues were derived from the residential, and
commercial/institutional markets, respectively. Of AMPAM's
commercial/institutional revenue, approximately 43% was derived from
institutional customers.

     AMPAM's strategy is to conduct its operations on a decentralized basis,
including among other things, retaining the operating names of its founding
companies in their respective regions. Senior management at the founding
companies will retain primary responsibility for operations, profitability and
growth of their respective business units. AMPAM believes that a decentralized
operating strategy, balanced by centralized financial and accounting controls,
will retain the entrepreneurial approach of the founding companies and preserve
AMPAM's knowledge of its individual markets, its extensive brand name
recognition and strong customer relationships. In addition, AMPAM believes that
this decentralized operating strategy will enable it to better respond to future
customer demand and changing market conditions.

(1) "CI" means a commercial/institutional market segment.

(2) "CAGR" means compound annual growth rate. With respect to some of the
    founding companies, the statement of operations data for the 1996 fiscal
    year was derived from internal financial company records that have not been
    audited by any independent accountants. Because the 1996-1998 CAGR of these
    companies, and of AMPAM on a combined basis, includes some unaudited 1996
    data you are cautioned not to place undue reliance on this information.
    Nevertheless, management believes that the financial information shown above
    may be helpful in understanding the past operations of the founding
    companies.

(3) Immediately following their acquisition, we combined the business and
    operations of Croson Ohio and Teepe's. Croson Ohio's fiscal 1998 revenues
    were $25.2 million and Teepe's fiscal 1998 revenues were $50.6 million.

INDUSTRY OVERVIEW

     General. Virtually all construction and renovation in the United States
generates demand for plumbing and mechanical contracting services. Depending
upon the exact scope of work, AMPAM estimates that the plumbing and mechanical
contracting work it performs generally accounts for approximately 8% to 12% of
the total construction cost of the related commercial and institutional projects
and approximately 5% to 10% of the total construction cost of the related
residential projects. In 1992, the most recent year for which data are available
from the United States Department of Commerce, the total value of new
construction and repair and maintenance work completed by plumbing and
mechanical contractors totaled approximately $28 billion, including
approximately $17 billion from plumbing services and $11 billion from mechanical
services.

     The plumbing and mechanical contracting service industry is highly
fragmented and we estimate it to include at least 40,000 companies. These
companies are generally small, owner-operated, independent contractors who serve
customers in a local market and therefore have limited access to capital for
investment in infrastructure, technology and expansion. According to our
estimates, approximately 200, or 0.5% of all industry participants, had annual
sales greater than $20 million, and no single company accounted for more than
1.0% of total expenditures for plumbing and mechanical contracting services in
the United States.

     Residential Market. Residential customers include regional and national
homebuilders and apartment and condominium developers. Typical residential
plumbing projects include the installation, maintenance and repair of domestic
water systems, sanitary waste and vent systems, lawn and garden irrigation
systems, fire protection systems and natural gas piping systems. The residential
construction market has increasingly become dominated by large regional and
national homebuilders, who have been rapidly consolidating or merging, and
national apartment or multifamily residential developers. AMPAM believes that
these large customers generally select plumbing and mechanical contractors with
a large, trained workforce that is able to meet the customer's location and
scheduling requirements and to provide reliable, high-quality services.
Substantially all of AMPAM's residential contracts are obtained on negotiated
terms through ongoing customer relationships versus through a competitive bid
process. The residential market has repetitive floor plans which enables AMPAM
to utilize its prefabrication techniques. In this way, AMPAM can increase
productivity and profitability by reducing construction time, labor costs and
skill requirements. In addition to installation, the residential market includes
substantial demand for maintenance and repair services, which are provided both
on a per visit basis and under short-term and long-term contracts.

     The residential market depends primarily on the number of single family and
multifamily home starts, which are in turn affected by interest rates, tax
considerations and general economic conditions. The founding companies serve
many of the more rapidly growing metropolitan areas, including Houston, San
Antonio, and Austin, Texas, Phoenix, Arizona, Las Vegas, Nevada, Atlanta,
Georgia, Orlando, Florida and Riverside and the San Fernando Valley, California.
These metropolitan areas have experienced significant new construction activity
for single family homes and low-rise multifamily residences over the last
several years and demographic trends indicate continued growth in these areas.
In 1998, AMPAM installed plumbing systems in over 20,000 new or renovated homes.
AMPAM's residential plumbing and mechanical contracting service revenues have
grown at an average compound annual rate of approximately 16% from the 1996
fiscal year through the 1998 fiscal year.

     Commercial/Institutional Market. Commercial and institutional customers
include general contractors, commercial developers, consulting engineers,
architects, owners and managers of retail establishments, office buildings,
apartments and condominiums, theaters and restaurants, hotels and casinos,
operators of waste water and water purification plants, manufacturing and other
industrial corporations, schools, hospitals, military and other governmental
agencies, stadiums, arenas and convention centers, airports and prisons.
High-rise residential projects are viewed as commercial rather than residential
projects because of the nature of the installation techniques and plumbing codes
involved. Because of the long-term nature of the budgetary processes involved,
government and institutional construction projects tend to be less affected by
economic downturns. In 1998, approximately 43% of AMPAM's revenues from the
commercial/institutional market were attributable to governmental and
institutional projects.

     Typically, plumbing and mechanical contracting services for the
commercial/institutional market involve the installation, maintenance and repair
of integrated systems that transport hot and chilled water, domestic water,
steam, medical gas, fuels and other liquid and gaseous substances and the
related equipment, such as water heaters, boilers, chillers, and pumps.
Commercial and institutional plumbing and mechanical construction is most often
performed by a subcontractor for a general contractor, although a plumbing and
mechanical contractor may also perform services directly as a prime contractor.

     Commercial/institutional contracts are obtained through a competitive bid
process or on negotiated terms through ongoing customer relationships. Many
larger projects have substantial bonding requirements that eliminate smaller
contractors from the bidding process because of inadequate financial resources
or capacity. As with the residential market, AMPAM is increasingly able in the
commercial and institutional markets to prefabricate system components off-site,
and these items are transported to the job site ready to be installed. The
commercial/institutional market also involves maintenance and repair of plumbing
and mechanical systems. AMPAM provides plumbing and mechanical contracting
services for the commercial/ institutional market in several of the country's
growth areas, including the southeastern, southwestern and western United
States. From the 1996 fiscal year through the 1998 fiscal year, AMPAM's revenues
from plumbing and mechanical contracting services for commercial and
institutional customers have grown at an average compound annual rate of
approximately 18% per year.

     Industry Trends. Significant consolidation has occurred among a number of
the industry's principal customers, such as homebuilders, apartment and
condominium developers and other commercial developers, REITs and other real
estate concerns and national contractors and construction managers.
Additionally, we believe the privitization of, or outsourcing by, water
utilities in many areas of the country may provide us with additional customer
opportunities. AMPAM has also witnessed significant consolidation within its
supply channels. We believe these consolidations present an opportunity for a
large, more proficient and professional company, like us, to consolidate and
provide plumbing and mechanical contracting services on a regional and national
basis.

     AMPAM believes that smaller, traditional plumbing and mechanical
contractors may find it increasingly difficult to compete for plumbing and
mechanical contracting projects due to scarcity of qualified manpower, customer
demand for broader geographic coverage and the associated licensing
requirements, costs associated with automating project bidding and estimating,
bonding and insurance requirements (including workers' compensation and
liability insurance) and manufacturers' discounts available to volume
purchasers. In the residential sector, AMPAM believes homebuilders will be
increasingly searching for contractors they can use in multiple capacities, a
"preferred provider," and that AMPAM will be able to take advantage of this
opportunity because of its size and diversity of operations.

COMPETITIVE STRENGTHS

     We believe several factors give us a competitive advantage in our industry,
including our:

     - Strong Customer Relationships and Market Leadership. We believe that our
       strong customer relationships and market reputation allows us the ability
       to obtain a high percentage of negotiated contracts, which are
       economically more favorable for us than competitive bid situations.
       Currently, approximately 75% of our business has been obtained through
       negotiated contracts. Our long-standing relationships also result in a
       significant amount of repeat business as well as the opportunity for
       cross-selling our services;

     - Geographically Diverse Operations. In 1998, we provided plumbing and
       mechanical contracting services in 24 states. We have operations in the
       higher growth southwest, southeast and western regions of the United
       States. We believe our broad geographic coverage will allow us to build
       and strengthen our relationships with large regional and national
       customers and will reduce the impact of local and regional economic
       downturns as well as minimize seasonal variations in activity;

     - Large Highly Skilled Work Force. We believe our size, national scope,
       stable and recurring project base, and comprehensive benefits packages
       and training programs allow us to attract and retain the most highly
       qualified personnel in the industry. We currently employee over 2,100
       technicians which enables us to deliver quality service with greater
       reliability than many of our competitors. This is particularly important
       given a current industry shortage of qualified plumbers;

     - Diverse Business Mix. We believe that our balanced customer base of
       residential, commercial, governmental and institutional work and our
       ability to offer both plumbing and mechanical contracting services
       provide us with greater stability both in revenues and cash flow. On a
       pro forma basis, no single customer represented more than 5% of our total
       1998 revenues; and

     - Experienced Management Team. Our chief executive and chief operating
       officer combined have over 65 years of experience in plumbing and
       mechanical contracting services and have developed extensive industry
       relationships. In addition, the presidents of our operating companies
       have an average of over 28 years in the industry and have established
       reputations in their local markets. The combined management team of AMPAM
       holds more than 76% of our company's outstanding common stock.

OUR BUSINESS STRATEGY

     Our goal is to build on our position as a leading provider of plumbing and
mechanical contracting services in the residential and commercial/institutional
markets by (1) increasing our market share and the profitability of our
operations; and (2) pursuing a selective acquisition strategy.

     OPERATING STRATEGY

          We intend to leverage the geographical presence and competitive
     strengths of our founding and subsequently acquired companies with the
     objective of continuing strong internal growth. We also believe that there
     are significant opportunities to increase the profitability of our business
     through the implementation of various best practices used by some of the
     founding companies throughout our operations. AMPAM has formed a Best
     Practices Committee consisting of various members of the management of the
     founding companies and smaller forum groups composed of representatives of
     similarly situated companies, all of which will meet regularly to
     facilitate communication and sharing of best practices. The key elements of
     our operating strategy are:

     - Achieve Purchasing Savings and Other Economies of Scale. As a result of
       AMPAM's size, it believes it will achieve substantial cost savings by
       purchasing copper, steel, cast iron, PVC and ABS pipe, plumbing fixtures,
       boilers, chillers and air handling equipment, pumps, drains, sprinkler
       systems and other materials. Our size will also enable us to purchase and
       negotiate rebates directly from manufacturers for high volume items. In
       1998, AMPAM's materials purchases were 51% of its total combined cost of
       revenues. In addition, AMPAM believes it can reduce costs associated
       with:

          (1) purchasing or leasing and routine maintenance of vehicles, cranes,
              backhoes, loaders, highlifts and other heavy equipment;

          (2) bonding, casualty and liability insurance;

          (3) health insurance and related benefits;

          (4) retirement benefits administration;

          (5) marketing and advertising; and

          (6) accounting, financial management and legal services;

     - Continue to Attract, Develop and Retain Qualified Plumbers and Management
       Personnel. AMPAM intends to provide:

          (1) stock-based compensation for a large portion of its employees;

          (2) progressive performance-based compensation for management;

          (3) recruitment and training programs to provide a steady labor
              supply, including state-registered apprenticeship programs;

          (4) advancement opportunities for talented employees within the larger
              public company; and

          (5) a broad-based health, disability and life insurance and retirement
              benefits program which is often not available from smaller
              plumbing and mechanical contracting services businesses;

     - Increase Off-site Prefabrication of Plumbing and Mechanical Systems and
       Components. AMPAM intends to increase the use of prefabricated components
       in the installation of plumbing and mechanical systems. Prefabrication
       generally involves measuring, cutting and assembling pipe segments and
       attaching various fittings and valves, which is particularly useful in
       the residential market where standard floor plans are often repeated.
       These fabricated segments are then numerically ordered and packaged
       together for installation at the job site. Prefabrication increases
       consistency and quality of work products and allows AMPAM to reduce
       on-site labor costs, materials costs and accelerate its on-site
       production schedule. In some of our regions, we have
                                       59
<PAGE>   66

       experienced a high degree of success in lowering labor costs, reducing
       materials usage and increasing standardization by fabricating portions of
       the plumbing and mechanical systems prior to installation at the job
       site. By sharing the most sophisticated and efficient prefabrication
       techniques currently utilized in some of our operating regions, AMPAM
       believes that it can increase the use of prefabrication to achieve
       meaningful cost reductions for AMPAM as a whole;

     - Emphasize "Value Engineering" and Design-and-Build Capability. In
       addition to the traditional installation of plumbing systems to the
       specifications set forth in architectural or engineering plans, AMPAM
       also provides "value engineering" and design-and-build capability. "Value
       engineering" involves the modification or enhancement of existing plans
       for plumbing and mechanical systems to improve efficiency and
       cost-effectiveness. AMPAM also provides full design-and-build services
       using its technical expertise to create designs for plumbing and
       mechanical systems. By providing this more sophisticated level of
       service, AMPAM is able to integrate itself with the customer earlier in
       the design process, thereby generating higher margins and differentiating
       itself from the competition;

     - Increase Use of Technology. AMPAM intends to take advantage of new and
       innovative technology currently utilized in some of our operating
       regions. AMPAM will use computer-assisted contract bid preparation and
       historical cost analysis in order to reduce the variances between the
       estimates used in the contract bidding process and the actual costs
       incurred. Additionally, AMPAM will expand its use of technology,
       including computer-aided design or "CAD" display stations used for
       project design and engineering;

     - Leverage Geographic Presence to Obtain and Retain Multi-Location
       Customers. AMPAM intends to enhance the sales and marketing programs of
       the founding companies to target large regional and national
       homebuilders, apartment and condominium developers and other commercial
       developers, REITs and other real estate concerns and national contractors
       and construction managers. AMPAM believes that significant demand exists
       from these companies to utilize the services of a single plumbing and
       mechanical contractor that has demonstrated consistent quality,
       dependability, bonding pre-qualification and financial stability; and

     - Broaden Scope of Specialty Services. AMPAM intends to broaden its service
       capabilities within its existing operating areas to provide an expanded
       range of plumbing and mechanical services without any significant
       incremental investment in infrastructure. Such complementary services
       include installation and maintenance of on-site and off-site utility
       systems, fire protection systems and HVAC systems.

     ACQUISITION STRATEGY

          We believe that the highly fragmented nature of the plumbing and
     mechanical contracting services industry offers significant opportunities
     for us to pursue our acquisition strategy. We have an acquisition team
     focused on identifying profitable acquisition candidates with leading
     market positions, stable operating histories, prospects for growth, strong
     management and entrepreneurial skills. We currently intend to acquire
     companies for a mix of common stock and cash. We are evaluating and have
     entered into confidentiality agreements with several acquisition
     candidates. Key elements of our acquisition strategy include:

     - Increase Geographic Coverage. We believe that increasing our geographical
       presence will allow us to build and strengthen our relationships with
       large, regional and national customers and will reduce the impact of
       local and regional economic downturns as well as minimize seasonal
       variations in activity. We intend to pursue acquisition candidates that
       serve geographic markets that we do not currently serve and have an
       appropriate customer base to integrate with or complement our existing
       business; and

                                       60
<PAGE>   67

     - Expand Our Service Capabilities. We will seek to acquire companies that
       offer diverse services which broaden our service capabilities within
       existing operational areas. We intend to pursue acquisition candidates
       who:

      - serve the commercial/institutional market in locations where we
        currently focus on the residential market, or vice versa;

      - offer expertise in higher margin complex installation projects, like
        waste water and water purification plants; and

      - focus on maintenance and repair services.

SERVICES

     Plumbing. Plumbing services provided by AMPAM consist primarily of the
installation of systems that convey domestic water throughout a building,
systems that transport sanitary waste out of a building to a sewer connection
and systems that transport natural gas to various equipment or appliances such
as heaters, boilers, ovens and stoves. A domestic water system typically
includes separate piping for hot and chilled water as well as a number of
fixtures such as sinks, bathtubs and showers and may also include the
installation of interior or exterior sprinkler systems and other specialty
purpose fixtures. A sanitary waste and vent system includes toilets, urinals and
piping to transport sanitary waste. A natural gas system typically includes
piping and connections to transport natural gas, including valves and other
equipment to regulate the natural gas flow. AMPAM also provides repair and
maintenance services for plumbing systems, primarily for systems which AMPAM
initially installed.

     For both residential and commercial/institutional customers, plumbing
contracting projects begin with project design and engineering in which the
locations, configuration and specifications for the plumbing systems to be
installed are determined. Whether the design is provided by the customer or
produced by AMPAM utilizing CAD technology, the type, size and design of piping,
fittings, valves, fixtures and other equipment is typically input into AMPAM's
computer systems which handle estimation, materials ordering and job scheduling
functions. Where appropriate, AMPAM plans to integrate its most advanced systems
into additional locations and areas of its operations to increase automation and
efficiency. Substantially all of the equipment and component parts AMPAM
installs are purchased from third-party wholesale suppliers or directly from the
manufacturers and resold to the customer as part of the contracted installation.
Orders and deliveries are coordinated to match the project schedule. Whenever
possible, a significant portion of the plumbing and piping assembly will be
prefabricated at AMPAM facilities in order to reduce on-site installation time,
increase quality control and reduce material costs. Such prefabrication
generally involves measuring, cutting and assembling pipe segments and attaching
various fittings and valves. These prefabricated segments are then numerically
ordered and packaged together for installation at the job site.

     Once the job moves onto the construction site, connections are made to the
municipal sewage system and supply and drainage piping is installed within the
construction "footings" along the building's perimeter. Risers are installed
which extend this piping above the level of the foundation. These risers are
designed either to be contained within the walls for extension into upper floors
or to connect with fixtures to be installed in specified locations on ground
level floors. After the foundation is poured and as framing for the walls and
floors of the upper levels of the building are constructed, piping systems are
extended to supply the fixtures and systems throughout the building.
Simultaneously, venting systems are installed which ultimately extend through
the roof of the structure. Once the walls have been covered and flooring,
ceilings and roofing completed, fixtures (including sinks, hot water heaters,
toilets, baths, faucets and spigots) are installed and the system is connected
to the water main and gas supply. Typically, plumbing personnel are on-site
during all phases of construction, as AMPAM assigns separate, specialized
plumbing crews to each specific required task (water and gas connections and
pressure testing, sewage connections, ground level piping, wall and ceiling
extensions and fixture installation). AMPAM believes that it increases its
efficiency and labor productivity by training crews to perform specialized
tasks. Municipal inspectors

                                       61
<PAGE>   68

also generally tour a job site several times during the construction process to
assure compliance with the applicable plumbing codes.

     Mechanical. Mechanical contracting services provided by AMPAM consist
primarily of the installation of mechanical and process piping and tubing,
including systems which convey hot and chilled water, steam, medical gas, fuels
and other liquid and gaseous substances, as well as the installation of related
equipment and fixtures which store, pump, regulate and measure the distribution
of these substances. In some cases, these mechanical systems installed by AMPAM
are critical to the underlying business of the future tenant, as in the case of
water treatment plants, chemical plants and medical laboratories. Mechanical
contracting services provided by AMPAM also include the installation of the
piping portion of HVAC systems, including the piping and tubing used to convey
hot and chilled water to the heating or cooling systems and the related boilers,
chillers, cooling towers, pumps, valves and control devices. See "-- HVAC"
below. AMPAM also provides repair and maintenance services for mechanical
systems on a per visit and short-term and long-term contract basis, primarily
for systems which AMPAM initially installed.

     Mechanical contracting projects begin with project design and engineering
which may be produced by AMPAM or specified by the customer. In response to
customer demand, AMPAM may develop some or all of the design parameters using
its CAD programs or may "value engineer" customer supplied specifications in
order to suggest more efficient installation configurations or lower cost
components. Prefabrication at AMPAM facilities may also be employed to
efficiently pre-assemble various piping and mechanical configurations prior to
deployment at the construction site. Most mechanical projects begin after the
foundation has been poured with the installation of distribution piping and duct
systems within the walls and between the floor and ceilings in accordance with
technical design specifications. Once the distribution and main service lines
have been installed, service branches to various equipment are completed, and
the equipment and controls are then balanced and commissioned.

     HVAC. In some regions, we also offer HVAC contracting services as a
complement to our plumbing and mechanical businesses. HVAC systems typically
involve piping and air-handling components. The piping component, as described
above, often is classified as a mechanical contracting service. The air-
handling component of an HVAC system includes the ductwork and ventilation
systems that carry air as opposed to hot or chilled water or other liquids or
gaseous substances. Equipment and fixtures related to the air-handling component
of an HVAC system include heaters, compressors, air handlers and air
conditioning units. Typically, HVAC installation projects begin with the
customer providing the architectural plans and mechanical drawings for the
building to be constructed. The process of on-site installation is similar to
that required for mechanical systems, with the installation of distribution
ductwork followed by the connection of service branches and the installation of
the appropriate HVAC equipment.

     Maintenance and Repair. Maintenance and repair contracting services are
generally provided on a per visit basis and through short-term and long-term
maintenance contracts. Revenue from repair and maintenance contracting services
has historically fluctuated, representing a larger portion of the overall
revenue of the founding companies when existing manpower capacity is not already
implemented on installation projects. AMPAM plans to expand its maintenance and
repair business through greater focus on promoting these services.

OPERATIONS

     Contracting. Residential work is generally obtained by relationships and
referrals, with pricing being negotiated between the homebuilder and the
plumbing subcontractor. Commercial and institutional work is typically awarded
through a competitive bid process, which is often limited to approved bidders
who meet bonding and other requirements. Often large projects attract fewer
bidders because smaller contractors are unable to meet the bonding and manpower
capacity requirements. Contracts may provide precise specifications for the work
to be completed, require the contractor to design and build the plumbing system
or may permit the contractor to provide revised specifications for the project.
AMPAM's plumbing contracts are generally structured on a fixed cost basis,
although repair and maintenance contracting

                                       62
<PAGE>   69

services are generally provided for on a fixed periodic fee or an hourly fee.
Revenues from a single residential plumbing contracting service project range
from approximately $350,000 to $550,000 for installation in a typical low-rise
apartment complex to approximately $1.5 million for installation in a typical
300-residence subdivision of new homes or approximately $5,000 per home.
Revenues from a single commercial or institutional mechanical contracting
project generally ranges from approximately $500,000 to $10 million, depending
upon the size of the building involved, the nature of the plumbing and
mechanical contracting services involved and the specific equipment and fixtures
to be installed. For example, revenue from a plumbing and mechanical project
involving a ten-floor high-rise apartment building may range from approximately
$650,000 to $1,000,000, whereas the revenues from a large plumbing and
mechanical contracting service project such as a stadium or industrial complex
may range from $5 million to $10 million.

     Engineering and Design. We have engineering and design capabilities which
enable us to offer a higher level of service to our customers. These
capabilities may be offered in-house or obtained from third parties, as
appropriate. CAD systems may be used to "value engineer" the project by
providing cost saving alternatives to the specifications and designs provided by
the customer or to actually design and build the plumbing and mechanical systems
to be installed. CAD systems can be used to automate the production of
blueprints, specifications and a schedule of required assemblies and to assist
in selecting the materials and equipment to be used. AMPAM plans to further
develop its "value engineering" and design-and-build capabilities to capture the
higher margins justifiable on account of the cost savings passed on to the
customer.

     Purchasing. AMPAM purchases copper, steel, cast iron, PVC and ABS pipe,
valves, hangers, fire protection and sprinkler systems and plumbing fixtures,
drains, water heaters, boilers, chillers, air handling units and pumps and other
materials from a number of manufacturers. AMPAM purchases these materials
directly from the manufacturer or through wholesalers and other distributors. In
some instances, AMPAM receives discounts from wholesalers in return for prompt
payment, and AMPAM plans to negotiate with wholesalers to receive discounts
whenever possible. AMPAM estimates that its cost of materials purchased
represents approximately 51% of AMPAM's costs of revenues. As a result of its
size following the acquisitions, AMPAM also plans to negotiate directly with the
national manufacturers to participate in rebate programs offered by these
manufacturers. AMPAM also believes it will be able to lower its costs for

     - the purchase or lease and maintenance of vehicles;

     - bonding, casualty and liability insurance;

     - health insurance and related benefits;

     - retirement benefits administration;

     - marketing and advertising; and

     - a variety of accounting, information, financial management and legal
       services.

     Management Information Systems and Controls. AMPAM intends to centralize
consolidated accounting and financial reporting activities at its corporate
headquarters while basic accounting activities will continue to be conducted at
the operating level. In addition, where an operating unit has a system in place
that is inadequate for its existing or near-term needs, AMPAM will implement
standards that will allow for greater consistency. In addition, several of the
founding companies, serving both the residential and commercial/institutional
markets, possess sophisticated (and in several cases proprietary) software
systems which handle estimation, materials ordering and job scheduling
functions. Where appropriate, AMPAM plans to integrate these advanced systems
into additional areas of its operations.

     Recruiting and Training. Recruiting and training will primarily occur at
the local level for each operating unit of AMPAM, but will also be supplemented
by national programs. AMPAM will share best practices in recruiting, selection
and training, to take advantage of the successful human resources, training and
apprenticeship programs developed by some of the founding companies. AMPAM plans
to offer state-
                                       63
<PAGE>   70

registered apprenticeship programs which use local inspectors and AMPAM
supervisory personnel as instructors. Upon completion of the program, each
apprentice will be a licensed plumber and placed on a AMPAM project where
needed. AMPAM believes it will be able to attract highly qualified candidates as
a result of its national size, potential for growth and advancement as well as
its health, disability and life insurance and retirement benefits packages and
stock-based compensation plans.

     Advertising and Marketing. AMPAM uses both local advertising and local
direct sales forces to market its commercial and residential services in its
geographic markets. AMPAM intends to preserve the value of the long-standing
trade names and customer identification enjoyed by the individual operating
units.

CUSTOMERS

     AMPAM has a diverse customer base with no one customer accounting for more
than 5% of AMPAM's pro forma combined revenues for the year ended December 31,
1998. As a result of an emphasis on quality and reliability, the founding
companies have been responsible for developing and maintaining successful
relationships with key customers. AMPAM intends to continue this emphasis on
superior quality and customer service in order to maintain these relationships.
We have provided plumbing and mechanical contracting services to numerous

     In addition to the facilities listed above, AMPAM may operate on a
short-term basis in other locations as may be required from time to time to
perform its contracts. AMPAM leases its principal and administrative offices in
Houston, Texas.

     AMPAM believes that its properties are generally adequate for its present
needs. Furthermore, AMPAM believes that suitable additional or replacement space
will be available as required.

COMPETITION

     The plumbing and mechanical contracting services industry is highly
fragmented and competitive and is generally served by a large number of small,
owner-operated private companies as well as several companies that provide some
of our plumbing and mechanical contracting services(often ancillary to a HVAC
focus) on a regional or national basis. Additionally, AMPAM could face
competition in the future from other competitors entering the market. Certain of
AMPAM's competitors may have greater financial and other resources than AMPAM
and may have lower overhead cost structures that may enable them to provide
services at lower prices than AMPAM. AMPAM believes that the primary competitive
factors in

                                       65
<PAGE>   72

the plumbing and mechanical contracting services industry are high quality
service, reliability and price. Other competitive factors in the plumbing and
mechanical contracting services industry include:

     - the availability of qualified and licensed plumbers and mechanics;

     - safety record;

     - cost structure;

     - relationships with customers;

     - relationships with plumbing component manufacturers;

     - geographic diversity;

     - ability to reduce project costs;

     - access to technology;

     - experience in specialized plumbing applications; and

     - ability to obtain bonding.

     Although AMPAM believes it is the first company to focus primarily on
consolidating the plumbing and mechanical contracting services industry, it will
compete with other existing companies for acquisitions and there can be no
assurance that other existing companies consolidating related industries or
yet-to-be-formed companies will not also adopt a similar focus. In particular,
other existing companies which are consolidating various aspects of the
residential and commercial contracting industry have focused on acquiring
companies that provide residential and commercial plumbing repair services and
residential and commercial HVAC installation and repair services. Some of these
existing companies have acquired companies engaged in the plumbing and
mechanical contracting services business with respect to new installations;
however, these companies have not represented a significant portion of the
overall revenues of the acquiring companies. Competition from existing companies
or yet-to-be-formed companies could have the effect of increasing the price for
acquisitions or reducing the number of suitable acquisition candidates. See
"Risk Factors -- The highly competitive nature of our industry could affect our
profitability by reducing our profit margins."

REGULATION

     Operations and Licensing. AMPAM's business and the activities are subject
to various federal, state and local laws, regulations, ordinances and policies
relating to, among other things:

     - the licensing and certification of plumbers and technicians;

     - AMPAM's advertising, warranties and disclosures to its customers;

     - the bidding process required to obtain plumbing and mechanical contracts;
       and

     - the applicable plumbing, mechanical and building codes with which AMPAM
       must comply.

     Most states require at least one of AMPAM's employees to be a licensed
master plumber, and many jurisdictions regulate the number and level of license
holders who must be present on a construction site during the installation of
plumbing and mechanical systems. Some jurisdictions require AMPAM to obtain a
building permit for each plumbing or mechanical project. In addition, AMPAM must
comply with labor laws and regulations, including those that relate to
verification by employers of legal immigration or work permit status of
employees.

     Environment, Health and Safety. AMPAM is subject to safety standards
established and enforced by the Occupational Safety and Health Administration
and environmental laws and regulations relating to the use, storage,
transportation and disposal of various materials. To the extent that AMPAM
performs work involving air conditioning and refrigeration systems, it is
subject to additional restrictions and regulations

                                       66
<PAGE>   73

governing the availability, handling and recycling of various refrigerants, due
to the phase-out of ozone-depleting substances under the Montreal Protocol and
the Clean Air Act.

LEGAL PROCEEDINGS

     Each of the founding companies has, from time to time, been a party to
litigation arising in the normal course of its business, most of which involves
claims for personal injury or property damage incurred in connection with its
operations. Management believes that none of these actions will have a material
adverse effect on the financial condition or results of operations of AMPAM.

EMPLOYEES

     At April 1, 1999, AMPAM had approximately 2,700 employees. Currently, none
of AMPAM's employees are members of unions or work under a collective bargaining
agreement. AMPAM believes that its relationship with its employees is
satisfactory.

COMMITTEES OF THE BOARD OF DIRECTORS

Stock Plan and the 1999 Directors Stock Plan, will be subject to prior review
and approval by the members of the Board of Directors without an interest in the
transaction.

     The Board of Directors is divided into three classes of directors, with
directors serving staggered three-year terms, expiring at the annual meeting of
stockholders following the 1999 fiscal year (Class I),
                                       69
<PAGE>   76

2000 fiscal year (Class II) and 2001 fiscal year (Class III), respectively. At
each annual meeting of stockholders, one class of directors is elected for a
full term of three years to succeed that class of directors whose terms are
expiring. The Board of Directors is classified as follows: Messrs. J. Croson, S.
Sherwood, Snyder and Miller are Class I directors, Messrs. R. Sherwood, D.
Croson, Christianson and Niemi are Class II directors and Messrs. Teepe,
Baggett, Richey and Ms. Rheney are Class III directors.

DIRECTOR COMPENSATION

     Directors who are employees of AMPAM or a subsidiary do not receive
additional compensation for serving as directors. Each director who is not an
employee of AMPAM or a subsidiary will receive a fee of $2,000 for attendance at
each Board of Directors meeting and $1,000 for each committee meeting (unless
held on the same day as a Board of Directors meeting). Directors of AMPAM will
be reimbursed for any reasonable out-of-pocket expenses incurred in attending
meetings of the Board of Directors or committees THEREOF, and for other expenses
reasonably incurred in their capacity as directors of AMPAM. Each non-employee
director receives stock options to purchase 5,000 shares of common stock upon
initial election to the Board of Directors and thereafter an annual grant of
5,000 options at each annual meeting on which the non-employee director
continues to serve. See "-- 1999 Stock Plan."

EXECUTIVE COMPENSATION

     The annualized base salaries of AMPAM's most highly compensated executive
officers are as follows: Robert A. Christianson -- $220,000; Robert C. Richey
 -- $220,000 and David C. Baggett -- $190,000.

EMPLOYMENT AGREEMENTS

     AMPAM is currently negotiating and expects to enter into an employment
agreement with each executive officer of AMPAM on substantially the same terms
and conditions as described in this and the following paragraphs. These
agreements will prohibit the officer from disclosing AMPAM's confidential
information and trade secrets and will generally restricts these individuals
from competing with AMPAM for a period of two years after the date of the
termination of employment with AMPAM. Each of the agreements will have an
initial term of five years and will provide for an annual extension at the end
of its initial term, unless either party timely notifies the other that the term
will not be extended, and will be terminable by AMPAM or by the officer upon
thirty days' written notice. The employment agreements will provide that AMPAM
will pay each officer the annual salary set forth above under "-- Executive
Compensation," which may be increased by the Board of Directors. Such agreements
will also provide that each officer will be reimbursed for out-of-pocket
business expenses and will be eligible to participate in all benefit plans and
programs as are maintained from time to time by AMPAM. All employment agreements
will provide that if the officer's employment is terminated by AMPAM without
"cause" or is terminated by the officer for "good reason," the officer will be
entitled to receive a lump sum severance payment at the effective time of
termination equal to the base salary (at the rate then in effect) for some
period of time. In this type of an event, the time period during which the
officer is restricted from competing with AMPAM will be shortened.

     The employment agreements will contain provisions concerning a
change-in-control of AMPAM, including the following:

     - in the event the officer's employment is terminated within two years
       following the change in control by AMPAM other than for "cause" or by the
       officer for "good reason," or the officer is terminated by AMPAM within
       three months prior to the change in control at the request of the
       acquiror in anticipation of the change in control, the officer will be
       entitled to receive a lump sum severance amount equal to the greater of
       (a) three years' base salary (at the rate then in effect) or (b) the base
       salary for whatever period is then remaining on the initial term, and the
       provisions which restrict competition with AMPAM will not apply;

     - in any change-of-control situation, the officer may elect to terminate
       his employment by giving five business days' written notice prior to the
       closing of the transaction giving rise to the change-in-
                                       70
<PAGE>   77

control, which will be considered to be a termination of employment by the
officer for "good reason," and the provisions of the employment agreement
governing the same will apply, except that the severance amount otherwise
      payable will be doubled (but not to exceed six times the officer's base
      pay) (if the successor does not give written notice of its acceptance of
      AMPAM's obligations under the employment agreement at least ten business
      days prior to the anticipated closing date, the severance amount will be
      tripled, but not to exceed nine times base salary), and the provisions
      which restrict competition with AMPAM will not apply; and

     - if any payment to the officer is subject to the 20% excise tax on excess
       parachute payments, the officer will be made "whole" on a net after-tax
       basis.

     A change in control is generally defined to occur upon:

     - the acquisition by any person of 20% or more of the total voting power of
       the outstanding securities of AMPAM;

     - the first purchase pursuant to a tender or exchange offer for common
       stock;

     - the approval of some types of mergers, sale of substantially all the
       assets, or dissolution of AMPAM; or

     - a change in a majority of the members of AMPAM's Board of Directors.

     In general, a "parachute payment" is any "payment" made by AMPAM in the
nature of compensation that is contingent on a change in control of AMPAM and
includes the present value of the accelerations of vesting and the payment of
options and other deferred compensation amounts upon a change in control. If the
aggregate, present value of the parachute payments to individuals, including
officers, equals or exceeds three times that individual's "base amount"
(generally, the individual's average annual compensation from AMPAM for the five
calendar years ending before the date of the change in control), then all
parachute amounts in excess of the base amount are "excess" parachute payments.
An individual will be subject to a 20% excise tax on excess parachute amounts
and AMPAM will not be entitled to a tax deduction for these payments.

1999 STOCK PLAN

     The Board of Directors of AMPAM adopted the 1999 Stock Plan. The purpose of
the 1999 Stock Plan is to provide officers, employees, directors and consultants
with additional incentives by increasing their ownership interests in AMPAM.
Individual awards under the Plan may take the form of one or more of:

        - non-qualified stock options ("NQSOs");

        - stock appreciation rights ("SARs");

        - restricted stock;

        - phantom stock;

        - performance awards;

        - bonus stock awards;

        - other stock-based awards, i.e., awards not otherwise provided for, the
          value of which are based in whole or in part upon the value of the
          common stock; and

        - cash awards that may or may not be based on the achievement of
          performance goals (collectively, "Awards").

     The performance goals for Awards, until changed, include target levels of
net income, cash flows, return on equity, profit margins, sales, stock price,
reductions in cost of goods sold and earnings per share.

                                       71
<PAGE>   78

'The Compensation Committee or AMPAM's Chief Executive Officer, to the extent
duties are delegated to the Chief Executive by the Compensation Committee,
administers the 1999 Stock Plan and selects the individuals who will receive
awards and establish the terms and conditions of those awards. The maximum
number of shares of common stock that may be subject to outstanding awards,
determined immediately prior to the grant of any award, may not exceed the
greater of 3,700,000 shares of common stock or 15% of the aggregate number of
shares of common stock then outstanding. Shares of common stock which are
attributable to awards which have expired, terminated or been canceled or
forfeited are available for issuance or use in connection with future awards.
The maximum number of shares of common stock with respect to which any person
may receive options and SARs in any calendar year is 200,000 shares. With
respect to other forms of awards, the maximum award that may be granted to any
individual in any calendar year cannot exceed $5.0 million (determined as of the
date of the grant of the award). Options and SARs may have exercise prices as
the Compensation Committee, in its discretion, determines.

     The 1999 Stock Plan will remain in effect for 10 years, unless earlier
terminated by the Board of Directors. The 1999 Stock Plan may be amended by the
Board of Directors or the Compensation Committee without the consent of the
stockholders of AMPAM, except that any amendment will be subject to stockholder
approval if required by any federal or state law or regulation or by the rules
of any stock exchange or automated quotation system on which the common stock
may then be listed or quoted.

     NQSOs to purchase 200,000 shares of common stock have been granted to David
C. Baggett, Chief Financial Officer and NQSOs to purchase 1,942,115 shares of
common stock have been granted to other members of management of AMPAM,
employees of the founding companies and holders of the preferred stock. Each of
the foregoing options have an exercise price of $7.00. These options will vest
at the rate of 20% per year, commencing on the first anniversary of grant and
will expire at the earliest of:

        - ten years from the date of grant;

        - three months following termination of employment or service, other
          than due to death or disability; or

        - one year following a termination of employment or service due to death
          or disability.

                              CERTAIN TRANSACTIONS

ORGANIZATION OF AMPAM

     AMPAM (1) issued 3,392,517 shares of common stock and restricted common
stock, to Sterling City Capital, LLC, the management of AMPAM and other
individuals and (2) granted options to purchase 2,142,115 shares of common stock
to various officers and employees of AMPAM, holders of the preferred stock and
other persons. The following executive officers and directors of AMPAM have been
issued the following number of shares of common stock and restricted common
stock, respectively: Mr. Snyder -- 0 and 1,598,901 (these shares are held in the
name of Sterling City Capital, LLC), Mr. Christianson -- 300,000 and 108,372,
respectively, Mr. Richey -- 150,000 and 54,186, respectively, Mr.
Baggett -- 300,000 and 108,372, respectively.

     Sterling City Capital, LLC advanced funds to AMPAM to pay for the expenses
related to the acquisitions. The advances totaled approximately $3.5 million
through the closing of the acquisitions and were repaid concurrently with
closing of the acquisitions in the form of a sponsor note. This note was repaid
with the proceeds of the original issuance of the notes.

ACQUISITION OF FOUNDING COMPANIES

     At the closing of the acquisitions, AMPAM purchased all the issued and
outstanding capital stock of the founding companies, at which time each founding
company became a wholly-owned subsidiary of AMPAM. The acquisition consideration
was negotiated by the parties and was based primarily upon the pro forma
adjusted net income of each founding company for prior historical periods, the
amounts of

                                       72
<PAGE>   79

indebtedness and working capital of each of the founding companies as well as
the future prospects of the businesses of each of the founding companies. The
acquisition consideration delivered upon the closing of the acquisitions
consisted of:

     - $99.9 million in cash (which represents a portion of the $106.3 million
       total cash consideration, subject to adjustment as discussed below, to be
       paid to the stockholders of the founding companies);

     - $5.8 million of seller notes;

     - 8,898,618 shares of common stock; and

     - 1,048,820 shares of preferred stock. Only some of the stockholders of
       Christianson received shares of preferred stock, and these stockholders
       did not receive any seller notes or shares of common stock.

     Included in the $99.9 million cash acquisition consideration paid upon
closing was a portion of the cash payments to be made to the stockholders of the
founding companies based upon the level of working capital of that founding
company as of the closing date. In the event that the adjusted level of working
capital as of the closing date is more or less than the unadjusted level, the
cash portion of the acquisition consideration payable to that stockholder will
be adjusted accordingly. The stockholders of each founding company were also
entitled to distributions of nonoperating assets of the founding company
(subject to assumption of related liabilities), retained earnings of the
founding company (if a C corporation) or the positive amount of the accumulated
adjustment account (if an S corporation). In addition to the acquisition
consideration and other payments and distributions described above, the
stockholders of each founding company (including some of the former stockholders
of Christianson) may receive additional consideration in the event the founding
company generates actual adjusted net income for the year ending December 31,
1999, in excess of a designated target level of net income for that period.

  ACQUISITION CONSIDERATION

     In addition to the $99.9 million in cash consideration and 8,898,618 shares
of common stock issued to stockholders of the companies, AMPAM issued
approximately $5.8 million in seller notes and 1,048,820 shares of preferred
stock. The principal features of the seller notes and preferred stock are set
forth below.

  Seller Notes

     Principal Amount and Interest Rate. Concurrently with the closing of the
acquisitions, AMPAM issued $5.8 million principal amount of seller notes due
three years from the date of issuance. The seller notes bore interest at the
rate of 10% per annum, and any overdue payments also bore interest at a rate of
10%.

     Interest Payment Dates. Interest on the seller notes was payable quarterly,
commencing 90 days from the date of issuance.

     Ranking. The seller notes were unsecured obligations of AMPAM, subordinated
in right of payment to any and all existing and future senior indebtedness of
AMPAM, including the credit facility.

     Redemption at the Option of AMPAM. The seller notes were redeemable at any
time, at the option of AMPAM, in whole or from time to time in part, at a price
equal to 100% of the principal amount plus accrued and unpaid interest, if any,
to the date of redemption.

     Redemption at the Option of Holders. In the event AMPAM completed a
qualified financing each of the holders of the seller notes would have had a
one-time "put right," but not an obligation, to require AMPAM to repurchase the
seller notes held by any holder, together with any accrued and unpaid interest,
if any, to the date of redemption, subject to some limitations. A "qualified
financing" meant the completion by AMPAM of (i) an initial public offering of
common stock or (ii) a private placement or

                                       73
<PAGE>   80

public offering of unsecured, senior subordinated or subordinated notes from
which AMPAM would have received at least $75 million in gross proceeds. The
consummation of the original issuance of the notes was a "qualified financing"
and all of the seller notes have been repaid in full.

  Series A Redeemable Preferred Stock

     Shares and Liquidation Value. An aggregate of 1,048,820 shares of preferred
stock were issued to some of the stockholders of Christianson at the closing of
the acquisitions. These Christianson stockholders received their acquisition
consideration solely in the form of cash and shares of preferred stock. The
preferred stock is cumulative, redeemable and convertible. The aggregate
liquidation value of the preferred stock is $13,634,660, plus accrued and unpaid
dividends, as adjusted proportionately for any stock dividends, combinations,
splits or other similar events with respect to those shares.

     Dividends. The holders of the preferred stock are entitled to receive
dividends at an annual rate of 10% based on the "liquidation value" of the
preferred stock. The dividends are payable in cash semiannually in arrears. The
dividend payment dates are June 30 and December 31, beginning on June 30, 1999.

     Ranking. The preferred stock ranks senior to all other classes of AMPAM's
capital stock, including the common stock, in right of liquidation, dividends
and distributions.

     Voting Rights. Except as set forth below, the preferred stock is not
entitled to vote as a separate class, but votes together with the holders of
shares of all other classes of capital stock of AMPAM as one class on all
matters submitted to a vote of AMPAM's stockholders. Each holder of shares of
preferred stock is entitled to the number of votes equal to the largest number
of full shares of common stock into which all shares of preferred stock held by
a holder could be converted at the record date for the determination of the
stockholders entitled to vote on those matters. In all cases where the holders
of shares of preferred stock are required by law to vote separately as a class,
the holders are entitled to one vote for each share.

     Without the affirmative vote of the holders of not less than a majority of
the shares of preferred stock, voting together as a single class, AMPAM may not
issue preferred stock having equal or superior rights to the preferred stock,
repurchase common stock or amend its charter documents in a manner which is
adverse to the holders of preferred stock.

     Additionally, at any time and for so long as either (i) AMPAM has failed to
punctually pay when due any redemption payment or (ii) dividends payable on the
preferred stock have been in arrears and unpaid for a period of forty days,
AMPAM shall not, without the affirmative vote of the holders of not less than a
majority of the shares of preferred stock, voting together as a single class:

     - incur any additional indebtedness for borrowed money other than
       borrowings under any credit facility to which AMPAM is a party at that
       time and as then in effect;

     - effect any (a) sale, lease, assignment, transfer or other conveyance of
       the assets of AMPAM or its subsidiaries which individually or in the
       aggregate would constitute a significant subsidiary, (b) consolidation or
       merger involving AMPAM or any of its subsidiaries, or (c) dissolution,
       liquidation or winding-up of AMPAM or any of its subsidiaries;

     - make (or permit any subsidiary to make) any loan or advance to, or own
       any stock or other securities of, any subsidiary or other corporation,
       partnership, or other entity unless it is wholly owned by AMPAM and
       except for any loans and advances which do not in the aggregate exceed
       $250,000;

     - make any loan or advance to any person, including, without limitation,
       any employee or director of AMPAM or any subsidiary, except advances and
       similar expenditures in the ordinary course of business; or

                                       74
<PAGE>   81

     - acquire, by purchase, exchange, merger or otherwise, all or substantially
       all of the properties or assets of any other corporation or entity.

     Redemption. The preferred stock is redeemable at AMPAM's option, at any
time and from time to time, in whole or in part, prior to an initial public
offering of common stock for the greater of (i) the fair market value of the
preferred stock and (ii) $13.00 per share of preferred stock, plus, in each
case, accrued and unpaid dividends thereon. After an initial public offering of
common stock, AMPAM has the right to redeem the preferred stock at any time and
from time to time, in whole or in part, at a price equal to the trading price of
the common stock at the time of redemption but in no event for less than $13.00
per share of preferred stock, plus accrued and unpaid dividends. After the third
anniversary of the date of issuance, the holders of the preferred stock may
require AMPAM to redeem the preferred stock. In each case, the redemption price
per share will be equal to the liquidation value plus accrued and unpaid
dividends through the date of redemption.

     Convertibility. Prior to the filing of a registration statement by AMPAM
with the Securities and Exchange Commission with respect to an initial public
offering of common stock, the holders of preferred stock may convert the
preferred stock into common stock on a share-for-share basis.

     AMPAM may convert the preferred stock following the completion of an
initial public offering of common stock on a share-for-share basis, unless this
conversion would result in the holder of preferred stock receiving common stock
having a value of less than $13.00 per share, in which case the conversion would
be made at a conversion ratio equal to the liquidation value (without inclusion
of accrued but unpaid dividends) divided by the price per share to the public in
the initial public offering of common stock.

 ADDITIONAL CONSIDERATION

     In addition to the acquisition consideration and the other payments and
distributions described above, the stockholders of each founding company, other
than Christianson, are entitled to receive additional consideration in the event
that founding company generates actual adjusted net income for the year ended
December 31, 1999 in excess of a designated target level of net income for that
period. This target net income for each founding company is generally an amount
equal to 107.5% of the founding company's pro forma adjusted net income for the
12-month period ended June 30, 1998.

     In the event that the adjusted net income for a founding company for the
year ending December 31, 1999 exceeds the target net income for that period, the
stockholders of that founding company will be entitled to receive additional
consideration, subject to a maximum amount of additional consideration as
described below, having a value equal to the product obtained by multiplying (1)
50% of the difference between adjusted net income of the founding company for
that period and the target net income by (2) ten. The amount of additional
consideration payable to the stockholders of a founding company eligible for
additional consideration is subject to a maximum limitation of 15% of the total
value of acquisition consideration paid to that stockholder upon the closing of
the acquisitions. Any additional consideration payable to stockholders of a
founding company will be paid 50% in cash and 50% in shares of common stock of
AMPAM. AMPAM's obligation to pay the cash portion of the additional
consideration is subject to the covenants, limitations and restrictions
contained in AMPAM's outstanding debt and equity instruments then in existence.

     Additionally, seven of the previous stockholders of Christianson, including
Robert A. Christianson, entered into employment agreements with Christianson
and/or AMPAM, effective upon the closing of the acquisitions. As part of the
compensation to be received by these individuals through their employment
agreements, they are entitled to receive additional consideration based on the
adjusted net income for Christianson for the year ending December 31, 1999 in
the same manner, subject to the same restrictions and determined by the same
methodology as described above for the stockholders of the other founding
companies.

                                       75
<PAGE>   82

  COVENANT NOT TO COMPETE

     Pursuant to the agreements relating to the acquisitions, all of the former
stockholders of each of the founding companies have agreed not to compete with
AMPAM in the plumbing and mechanical contracting services business for a period
of two years after the closing of the acquisitions. In addition, some of the
management personnel of each of the founding companies will enter into
employment agreements through which these persons will agree not to compete with
AMPAM in the plumbing and mechanical contracting services business for a period
of two years after the termination of their affiliation with AMPAM. In
connection with the acquisitions, AMPAM and the owners of the founding companies
have agreed to indemnify each other for breaches of representations and
warranties and other matters, subject to limitations.

  COMMON STOCK REDEMPTION RIGHTS

     Redemption Trigger. In the event that within three years of the closing of
the acquisitions, (1) AMPAM has not consummated an initial public offering of
common stock and (2) any stockholder of any founding company has not received
cash (including the proceeds from the public or private sale of common stock and
the receipt of principal payments, if any, on the seller notes held by that
stockholder) equal to or exceeding 50% of the aggregate value of the acquisition
consideration received by each stockholder through his or her respective
acquisition agreement, each stockholder will have a "put right," to require
AMPAM to purchase a number of shares of common stock representing 10% of the
total number of shares of common stock then owned by that stockholder, subject
to the limitations described below. The purchase price for this redemption will
be $13.00 per share of common stock.

     Minimum Redemption; Limitations. If the events specified in clauses (1) and
(2) above, have not occurred within the time specified, AMPAM will be obligated
to purchase annually from each eligible stockholder no less than 10% of the
common stock held by that stockholder; provided, however, that an eligible
stockholder will not be entitled to exercise his or her put right if and to the
extent that the stockholder's founding company has not achieved the target net
income for that founding company for the year preceding the year the stockholder
seeks to exercise his put right. AMPAM's obligation to effect these redemptions
will be subject to the covenants, limitations and restrictions contained in
AMPAM's outstanding private or public debt and equity instruments then in
existence.

     Additional Redemptions. In the event an initial public offering of common
stock has not been consummated, to the extent the stockholders who have received
greater than 50% of their acquisition consideration in cash wish to tender
common stock to AMPAM for purchase, AMPAM will use its commercially reasonable
efforts to continue to repurchase annually up to 10% of the common stock held by
those stockholders. AMPAM's obligation to make any additional redemptions will
also be subject to any covenants, limitations or restrictions contained in
AMPAM's outstanding private or public debt and equity instruments then in
existence.

     Termination of Redemption Obligation. The put rights with respect to any
individual stockholder will terminate upon receipt by a stockholder of 50% of
his acquisition consideration in cash. This termination will not, however, limit
the stockholder's ability to participate in the additional redemptions described
above. Notwithstanding the foregoing, all of AMPAM's redemption obligations
under the acquisition agreements will terminate on the earlier to occur of (1)
an initial public offering of common stock, (2) any sale of all or substantially
all of AMPAM's assets in one transaction or series of transactions, (3) any
merger or consolidation which involves AMPAM and in which AMPAM is not the
surviving entity or (4) any transaction after which the shares of common stock,
if any, which are then held by persons other than the holders of common stock as
of the closing date of the acquisitions constitute 50% or more of the shares of
common stock outstanding as of the date of the closing of the transaction.

OTHER TRANSACTIONS INVOLVING CERTAIN OFFICERS, DIRECTORS AND SHAREHOLDERS

     Christianson leases some facilities from the Glen T. Christianson Family
Trusts, W. George Christianson, Jr. Family Trusts, Robert A. Christianson Family
Trusts, and Wilburn G. Christianson Family Trusts. Amounts paid through these
leases were $156,000 for the 1996 fiscal year, $466,000 for the 1997 fiscal year
and $492,000 for the 1998 fiscal year. Future minimum lease payments under these
noncancelable operating leases are $495,000 for 1999, $554,000 for 2000,
$559,000 for 2001, $69,000 for 2002 and $24,000 for 2003. AMPAM believes that
these rents are not in excess of the fair rental value for these facilities.
Glen Christianson and George Christianson are brothers of and Wilburn
Christianson is the father of Robert Christianson who is the Chief Executive
Officer and a director of AMPAM.

     Through December 31, 1995, Christianson subcontracted its construction
labor to Contractor Resources, Inc., a company which is wholly-owned by Robert
Christianson. Christianson was charged for this labor based on Contractor
Resources' actual costs. For the 1996 fiscal year, and the four months ended
December 31, 1995, subcontractor labor costs reflected within cost of revenues
in the accompanying statements of operations were $2,663,000 and $2,663,000,
respectively. This relationship was terminated effective December 31, 1995.

     Also through December 31, 1995, Contractor Resources provided workers'
compensation insurance to Christianson's employees through a self-insurance
program. Contractor Resources charged Christianson an agreed-upon rate for this
insurance based on an estimate of the cost of workers' compensation insurance as

                                       77
<PAGE>   84

a subscriber under the Texas risk pool. Claims were administered and paid by
Contractor Resources. For the 1996 fiscal year, and the four months ended
December 31, 1995, workers' compensation insurance costs reflected within cost
of revenues in the accompanying statements of operations were $268,000 and
$268,000, respectively. This relationship was terminated effective December 31,
1995.

     Effective January 1, 1999, Christianson entered into a 7 year operating
agreement with Contractor Resources to lease some furniture for an annual lease
payment of $63,000.

     Also, Robert Christianson's employment agreement with AMPAM contains a
provision whereby Robert Christianson may earn additional consideration. See
"Certain Transactions -- Acquisition of Founding Companies -- Additional
Consideration."

     G.G.R. Leasing Corporation, d.b.a. Professional Services, Inc.
("Professional Services"), a company in which Robert Christianson had a
one-third ownership interest prior to the closing of the acquisitions, provided
various administrative and management services to Christianson Enterprises, Inc.
In connection with these services, Professional Services charged a fee to
Christianson. For the 1996 fiscal year, and the four months ended December 31,
1995, Professional Services charged Christianson $225,000 and $225,000,
respectively. These amounts are included within other income in the accompanying
statements of operations. As discussed above, the relationship was terminated
December 31, 1995; therefore, no fees were charged subsequent to this date.

     Mr. Richey was a part owner in a partnership which leased vehicles to RCR
at rates approximating market. During 1996, the partnership contributed these
leased vehicles to RCR, at their historical cost, less accumulated depreciation.
Upon the contribution of these assets, the net book value approximated zero. Mr.
Richey is the Chief Operating Officer and a director of AMPAM.

     A partnership owned by Mr. Richey leased steel storage containers to RCR at
rates approximating market rates. During 1996, the partnership contributed all
of RCR's leased steel storage containers. These assets were contributed at the
approximate historical cost, less accumulated depreciation, of approximately
$37,000.

     A partnership owned by Mr. Richey leased some equipment to RCR, at rates
approximating market rates. RCR incurred lease expense under this arrangement of
approximately $87,000, $52,000 and $77,000 for the 1996, 1997 and 1998 fiscal
years, respectively.

     RCR funds three life insurance policies for Mr. Richey and some other
parties affiliated with RCR. Two of the policies name RCR as the beneficiary.
Total payments for these policies approximated $41,000, $29,000 and $12,000 for
the 1996, 1997 and 1998 fiscal years.

     RCR leases some facilities from Mr. Richey. Lease expense related to these
buildings totaled approximately $220,000, $220,000 and $220,000 for the 1996,
1997 and 1998 fiscal years, respectively. Future minimum lease payments under
this lease are approximately $233,400 for 1999, $240,400 for 2000, and $123,500
for 2001. AMPAM believes that this rent is not in excess of the fair rental
value for this property.

     In 1997, Teepe's entered into an operating lease for some facilities with
Teepe, Ltd., of which Scott W. Teepe, Sr. and Steven M. Teepe each own 50%. The
lease expires in August 2003 with an option to renew for two five-year terms.
The lease calls for monthly lease payments of approximately $5,000. Total rent
paid under this lease was $18,000 and $55,000 in 1997 and 1998, respectively.
Future minimum yearly lease payments under this lease are $60,000 for 1999
through 2003. AMPAM believes that this rent is not in excess of the fair rental
value for this property. Steven M. Teepe's brother, Scott W. Teepe, Sr., is a
director of AMPAM.

     As of December 31, 1997 and 1998, Teepe's has an outstanding loan to Steven
M. Teepe. The loan is classified as other receivables for balance sheet
presentation. The loan to Steven M. Teepe had an outstanding balance of $114,000
and $122,940 at December 31, 1997 and 1998, respectively. The loan bears
interest at the blended federal rate (5.9% at December 31, 1997 and 1998). Total
interest income related to this loan was $7,000 for the 1997 and 1998 fiscal
years.

     In July 1998, Teepe's sold some property to an entity controlled by Scott
W. Teepe, Sr. Concurrent with the sale, Teepe's entered into a lease with the
entity for the same property. The lease calls for monthly lease payments of
approximately $12,000.

     On March 1, 1995, Croson Ohio sold some facilities to David Croson for
$500,000. Croson Ohio now leases these facilities from David Croson. David
Croson's mortgage on these facilities is guaranteed by Croson Ohio. In 1996,
1997 and 1998, Croson Ohio made yearly lease obligation payments to David Croson
in the amount of $99,600. As of September 30, 1997 and 1998, Croson Ohio owed
David Croson $537,743 and $484,155, respectively. Future minimum lease payments
are $213,000 for 1999, $159,000 for 2000, $106,000 for 2001, $100,000 for 2002,
and $241,000 for each year thereafter. David Croson and his father, James
Croson, are both directors of AMPAM.

     Croson Florida leases some property and facilities from James Croson under
a noncancelable operating lease expiring in September 2002. Rent expense under
this Lease was approximately $32,000 for each of the 1996 and 1997 fiscal years,
and $24,000 for the 1998 fiscal year. Future minimum yearly lease payments under
this lease are approximately $22,000. AMPAM believes that these rents are not in
excess of the fair rental value for these properties.

     Croson Florida has a Subordinated Note Agreement with James Croson, with a
balance of $434,000 at December 31, 1997 and $0 at December 31, 1998. Interest
is due quarterly at the rate of prime plus 2% (9.75% at December 31, 1998).
Principal is due in full on December 15, 2002.

     During the 1996 and 1997 fiscal years, Croson Florida purchased supplies
from Eastway Supplies, Inc., a company in which James Croson had a 35% ownership
interest. Croson Florida's purchases totaled approximately $81,000, $48,000 and
$0 for the 1996, 1997 and 1998 fiscal year, respectively. No amounts were owed
to Croson Florida at December 31, 1997 and 1998. James Croson was also a
director of Eastway Supplies, Inc., until 1996. At December 31, 1997, James
Croson no longer owned any interest in Eastway Supplies, Inc.

     Sherwood entered into a construction contract with Poway Land Associates,
LLC, which is 90% owned by Mr. Sherwood. The total contract receivable balance
as of September 30, 1997 and 1998 was approximately $302,000 and $88,000,
respectively. Sherwood recorded construction revenue and gross margin for this
contract of approximately $457,000 and $23,000 for 1997, and approximately
$475,000 and $(112,000) for 1998, respectively. Mr. Sherwood is a director of
AMPAM.

     Poway Land Associates, LLC, leases some facilities to Sherwood. Amounts
paid through this lease were $78,000 for the 1997 fiscal year and $97,000 for
the 1998 fiscal year. Future minimum lease payments under the lease, which
expire in May 2003 are $126,000 for 1999, $129,000 for 2000, $133,000 for 2001,
$137,000 for 2002, and $129,000 for 2003. AMPAM believes that the leases are not
in excess of fair rental value for these facilities.

     As of September 30, 1998 and 1997, Mr. Sherwood had an outstanding loan to
Sherwood with a balance of $63,000 and $83,000, respectively. The indebtedness
was originally incurred in June 1997.

     Miller purchased various materials and supplies from North Georgia Supply
and Appliance Company, a company in which Joseph H. Miller is a part owner.
Miller also bills salaries, insurance, and office supplies to North Georgia
Supply and Appliance Company. Miller purchased approximately $1,940,000 of
material and supplies from North Georgia Supply and Appliance Company in 1997,
and $3,048,000 in 1998. Miller had receivables of $195,334 due from North
Georgia Supply and Appliance Company at September 30, 1997 and $8,241 at
September 30, 1998.

     Miller leases some facilities from Joseph H. Miller under a lease agreement
that expires on September 30, 2005. Rent expense for the years ended September
30, 1997 and 1998 was $90,000. Future yearly lease payments for fiscal years
1999 through 2005 are $90,000. AMPAM believes that this rent is not in excess of
the fair rental value for this property. Joseph E. Miller, a director of AMPAM,
is the son of Joseph H. Miller.

                       DESCRIPTION OF OTHER INDEBTEDNESS

     Assuming the original issuance of the notes had occurred on March 31, 1999,
AMPAM's indebtedness would have consisted of approximately $3.1 million of
capital lease obligations. In addition AMPAM will be able to borrow up to $95.0
million under its credit facility, subject to the conditions set forth in the
credit facility. The terms of our credit facility are substantially as follows:

     Commitment; Interest Rates. The credit facility is a senior secured
revolving credit facility in an aggregate principal amount of $95 million which
includes a sublimit for the issuance of standby letters of credit. Amounts
borrowed under the credit facility were used to fund a part of the cash portion
of the acquisition consideration and will be used to fund future acquisitions
and to provide financing for general corporate purposes. The credit facility
bears interest, at the option of AMPAM, at the base rate of the arranging bank
plus an applicable margin or at LIBOR plus an applicable margin. The applicable
margin will fluctuate based on AMPAM's ratio of funded debt to EBITDA. The
applicable margin will be between 1.50% and 2.50% above LIBOR or 0.00% and 1.00%
above the arranging banks base rate.

     Repayment; Maturity. Interest will be payable no less frequently than
quarterly in arrears. The term of the credit facility will be three years from
the date of the closing of the acquisitions (April 1, 1999), and all principal
amounts borrowed thereunder will be payable in full at maturity.

     Security and Guarantees. The obligations of AMPAM under the credit facility
are secured by a first priority perfected security interest in (1) all the
accounts receivable, inventory, equipment and other personal property of AMPAM
and (2) all of the capital stock owned by AMPAM of its existing or later-formed
domestic subsidiaries. Also, the obligations of AMPAM are guaranteed by the
founding companies.

     Prepayments. AMPAM is required to make prepayments or commitment reductions
on the credit facility in an amount equal to:

     - 100% of the cash proceeds from any property insurance recoveries not
       promptly applied toward the repair or replacement of the damaged
       property;
     - 100% of the net proceeds of the sale of any equity securities; and
     - 100% of the net proceeds of any public or private debt financing.

     Conditions and Covenants. The obligations of the lenders under the credit
facility are subject to the satisfaction of conditions precedent customary under
similar credit facilities or otherwise appropriate under the circumstances.
AMPAM is subject to customary negative covenants contained in the credit
facility, including without limitation covenants that restrict, subject to
specified exceptions:

     - the incurrence of additional indebtedness;
     - asset sales;
     - capital expenditures;
     - mergers, acquisitions, consolidations and liquidations;
     - transactions with affiliates;
     - permitted investments; and
     - the ability of AMPAM to make various payments (including payments of the
       cash portion of the additional consideration and for redemption of common
       stock), to incur guaranty obligations and to incur additional liens.

The credit facility also contains customary affirmative covenants, including:

     - the delivery of financial statements, reports, accountants' letters,
       projections, officers' certificates and other information requested by
       the lenders;
     - the continuation of business and maintenance of material rights and
       privileges;
     - the payment of other obligations;
     - maintenance of property and insurance;
     - maintenance of books and records;
     - compliance with environmental laws;
                                       81
<PAGE>   88

     - the right of the lenders to inspect AMPAM's property and books; and
     - notice of defaults, litigation and other material events.

       In addition, the credit facility requires AMPAM to maintain compliance
with a number of specified financial covenants including:

     - a maximum ratio of funded total debt to EBITDA of no more than 4.0 to 1.0
       calculated on a rolling four quarter basis;
     - a maximum ratio of funded senior debt to EBITDA of no more than 2.5 to
       1.0 calculated on a rolling four quarter basis;
     - a minimum fixed charge coverage ratio of at least 1.0x to 1.25x
       calculated on a rolling four quarter basis; and
     - a minimum net worth with quarterly step-ups equal to 75% of positive net
       income and 100% of net proceeds from equity issuances.

     Events of Default. The credit facility includes events of default that are
usual and customary under similar credit facilities, including without
limitation, failure to pay principal, failure to pay interest or fees, cross
default on other indebtedness:

     - change of control of AMPAM;

     - breach of covenants;

     - material judgments rendered against AMPAM;

     - ERISA events; and

     - a material inaccuracy in any representation or warranty. The occurrence
       of any of these events of default could result in the acceleration of
       AMPAM's obligations under the credit facility which, in turn, could have
       a material adverse effect on AMPAM's operations.

                            DESCRIPTION OF THE NOTES

     You can find the definitions of capitalized terms used in the following
description under the subheading "-- Certain Definitions." In this description,
the words "AMPAM," "we," "our," "ours," and "us" refers only to American
Plumbing & Mechanical, Inc. and not to any of its subsidiaries.

     We will issue the exchange notes under an indenture among AMPAM, the
guarantors and State Street Bank and Trust Company, as trustee. The terms of the
notes include those stated in the indenture and those made part of the indenture
by reference to the Trust Indenture Act of 1939.

     The following description is a summary of the material provisions of the
indenture. It does not restate the indenture in its entirety. We urge you to
read the indenture because it, and not this description, defines your rights as
holders of these notes. We have filed a copy of the indenture as an exhibit to
the registration statement which includes this prospectus.

BRIEF DESCRIPTION OF THE NOTES AND THE GUARANTEES

  THE NOTES

     These notes:

     - are general obligations of AMPAM;

     - are subordinated in right of payment to all existing and future Senior
       Indebtedness of AMPAM;

     - are senior in right of payment to any future Subordinated Indebtedness of
       AMPAM; and

     - are fully and unconditionally guaranteed by the guarantors.

  THE GUARANTEES

     These notes are guaranteed by all of the current direct subsidiaries of
AMPAM.

     The guarantees of these notes:

     - are general obligations of each guarantor;

     - are subordinated in right of payment to all existing and future Guarantor
       Senior Indebtedness; and

     - are senior in right of payment to any future Subordinated Indebtedness of
       each guarantor.

     As of the date of the indenture, all of our subsidiaries were Restricted
Subsidiaries. However, under the circumstances described below, we will be
permitted to designate some of our subsidiaries as Unrestricted Subsidiaries.
Unrestricted Subsidiaries will not be subject to many of the restrictive
covenants in the indenture. Unrestricted Subsidiaries will not guarantee these
notes.

     As of the date of this prospectus, all of our subsidiaries were guarantors
of these notes. It is possible that in the future not all of our Restricted
Subsidiaries will guarantee these notes. In the event of a bankruptcy,
liquidation or reorganization of any of these non-guarantor subsidiaries, these
non-guarantor subsidiaries will pay the holders of their debt and their trade
creditors before they will be able to distribute any of their assets to us.

MATURITY, INTEREST AND PRINCIPAL

     We will issue exchange notes with a maximum aggregate principal amount of
$125 million. We will issue exchange notes in denominations of $1,000 and
integral multiples of $1,000. The exchange notes will mature on October 15,
2008.

     Interest on these notes will accrue at the rate of 11 5/8% per year and
will be payable semi-annually in arrears on April 15 and October 15, commencing
on October 15, 1999. We will make each interest

                                       83
<PAGE>   90

payment to the holders of record of these notes on the April 1 and October 1
immediately before each payment date.

     Interest on these notes will accrue from the date the existing notes were
issued or, if interest has already been paid, from the date it was most recently
paid. Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months.

OPTIONAL REDEMPTION

     After April 15, 2004, we may redeem all or a part of these notes upon not
less than 30 nor more than 60 days' notice, at the redemption prices (expressed
as percentages of principal amount) set forth below, plus accrued and unpaid
interest, if any, to the redemption date, if redeemed during the 12-month period
beginning April 15 of the years indicated below:

2006........................................................    102.000%
2007 and thereafter.........................................    100.000%
</TABLE>

     In addition, at any time, or from time to time, on or prior to April 15,
2002, AMPAM may, at its option, use the net cash proceeds of one or more Public
Equity Offerings to redeem up to an aggregate of 35% of the principal amount of
the notes originally issued, at a redemption price equal to 111.625% of the
principal amount of the notes plus accrued and unpaid interest, if any, thereon
to the redemption date; if that at least 65% of the originally issued principal
amount of notes remains outstanding immediately after the occurrence of this
redemption. In order to effect this redemption with the proceeds of any Public
Equity Offering, AMPAM must consummate this redemption not later than 60 days
after the closing of any Public Equity Offering.

SELECTION AND NOTICE

     If less than all of the notes are to be redeemed at any time, the trustee
will select notes for redemption as follows:

     - if the notes are listed, in compliance with the requirements of the
       principal national securities exchange on which the notes are listed; or

     - if the notes are not listed, on a pro rata basis, by lot or by any method
       the trustee shall determine to be fair and appropriate.

     No notes of $1,000 or less shall be redeemed in part. Notices of redemption
shall be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each holder of notes to be redeemed at its registered
address.

     If any note is to be redeemed in part only, the notice of redemption that
relates to that note shall state the portion of the principal amount to be
redeemed. A new note in principal amount equal to the unredeemed portion of the
original note will be issued in the name of the holder of the original note upon
cancellation of the original note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue on notes or portions of them called for redemption, unless AMPAM defaults
in the payment of the redemption price.

CHANGE OF CONTROL

     Upon the occurrence of a Change of Control, AMPAM shall be obligated to
make an offer to purchase all of the outstanding notes at a purchase price equal
to 101% of the principal amount of the

                                       84
<PAGE>   91

notes plus accrued and unpaid interest, if any, on the notes to the date the
offer is completed. AMPAM shall be required to purchase all notes properly
tendered and not withdrawn.

     In order to effect a Change of Control offer, AMPAM must mail to each
holder of notes notice of the Change of Control offer no later than 30 days
after the Change of Control takes place. We must complete the offer on a
business day not less than 30 days nor more than 60 days after the mailing of
the notice of the Change of Control. We are required to keep the offer open for
at least 20 business days. The notice governs the terms of the offer and states
the procedures that holders of notes must follow to accept the offer.

     If a Change of Control offer is made, AMPAM cannot give any assurance that
it will have available funds sufficient to pay the purchase price for all of the
notes that might be delivered by holders of notes seeking to accept the Change
of Control offer. In addition, AMPAM cannot give any assurance that its debt
instruments will permit an offer to be made. AMPAM's credit facility does not
permit AMPAM to make a Change of Control offer. In order to make this type of
offer, AMPAM would be required to pay off the credit facility in full or seek a
waiver from the lenders under the credit facility to allow AMPAM to make the
Change of Control offer.

     The occurrence of a Change of Control is also an event of default under the
credit facility and would entitle the lenders under the credit facility to
accelerate all amounts owing under the credit facility. Any future credit
agreements or other agreements relating to Senior Indebtedness to which AMPAM
becomes a party may contain similar restrictions and provisions. Moreover, the
exercise by the holders of their rights to require AMPAM to repurchase the notes
could cause a default under indebtedness of the type described, even if the
Change of Control itself does not, due to the financial effect of this type of
repurchase on AMPAM. AMPAM's failure to make a Change of Control offer, even if
prohibited by AMPAM's debt instruments, would constitute a default under the
indenture. See "Risk Factors."

     AMPAM shall not be required to make a Change of Control offer upon a Change
of Control if a third party makes the Change of Control offer at the same
purchase price, at the same time and otherwise in compliance with the
requirements applicable to a Change of Control offer made by AMPAM and purchases
all notes validly tendered and not withdrawn under a Change of Control offer.

     In addition, AMPAM shall not be required to make a Change of Control offer,
as provided above, if, in connection with or in contemplation of any Change of
Control, it has made an offer to purchase any and all notes validly tendered at
a cash price equal to or higher than the Change of Control purchase price and
has purchased all notes properly tendered in accordance with the terms of this
alternate offer.

     The provisions of the indenture may not afford Note holders protection in
the event of a highly leveraged transaction, reorganization, restructuring,
merger or similar transaction involving AMPAM if the transaction is not a
transaction defined as a "Change of Control." The existence of a holder's right
to require AMPAM to repurchase the notes upon a Change of Control may deter a
third party from acquiring AMPAM in a transaction that constitutes, or results
in, a Change of Control.

     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of AMPAM and its Subsidiaries taken as a whole. Although there is
a limited body of case law interpreting the phrase "substantially all," there is
no precise established definition of the phrase under applicable law.
Accordingly, the ability of a holder of notes to require AMPAM to repurchase
their notes as a result of a sale, lease, transfer, conveyance or other
disposition of less than all of the assets of AMPAM and its Subsidiaries taken
as a whole may be uncertain.

     AMPAM will comply with Rule 14e-1 under the Exchange Act and any other
securities laws and regulations, to the extent these laws or regulations are
applicable, in connection with a repurchase of notes resulting from a Change of
Control. Any violation of the provisions of the indenture relating to this type
of offer shall not be considered to be a default or an event of default.

                                       85
<PAGE>   92

SUBORDINATION

     The payment of principal, premium and interest, if any, on these notes will
be subordinated to the prior payment in full of all Senior Indebtedness of
AMPAM. The credit facility provides that the subordination provisions of the
notes may not be modified or amended without the prior written consent of the
lenders under the credit facility.

     The holders of Senior Indebtedness (including, in the case of Designated
Senior Indebtedness, any interest accruing subsequent to the filing of a
petition for bankruptcy regardless of whether interest is an allowed claim in
the bankruptcy proceeding) will be entitled to receive payment in full before
the holders of notes will be entitled to receive any payment related to the
notes (except that holders of notes may receive and retain Permitted Junior
Securities and payments made from the trust described under "-- Legal Defeasance
or Covenant Defeasance of Indenture"), in the event of any distribution to
creditors of AMPAM:

     - in a liquidation, dissolution or winding up of AMPAM;

     - in any insolvency or bankruptcy case or proceeding or any receivership,
       liquidation, reorganization or other similar case or proceeding relating
       to AMPAM or its assets;

     - in an assignment for the benefit of creditors; or

     - in any marshalling of our assets and liabilities.

     We also may not make any payment in respect of the notes (except in
Permitted Junior Securities or from the trust described under "-- Legal
Defeasance or Covenant Defeasance of Indenture") if:

     - a payment default on Senior Indebtedness occurs and is continuing and the
       trustee and AMPAM receive a notice from representatives of the holders of
       the Senior Indebtedness; or

     - any other default occurs and is continuing on Designated Senior
       Indebtedness that permits holders of the Designated Senior Indebtedness
       to accelerate its maturity and the earlier of either of the following;
       (a) the trustee and AMPAM receive a notice of the default from
       representatives of the holders of the Designated Senior Indebtedness or
       (b) if the default is the result of the acceleration of the maturity of
       the notes, the date of the acceleration.

     Payments on the notes may and shall be resumed:

     - in the case of a payment default, upon the date on which the default is
       cured, waived or ceases to exist or the Senior Indebtedness is paid in
       full or indefeasibly discharged; and

     - in case of a nonpayment default, the earlier of

        (a) the date on which the nonpayment default is cured, waived or ceases
        to exist or the Senior Indebtedness is paid in full or indefeasibly
        discharged;

        (b) 179 days after the date on which the notice of default is received
        or the date of acceleration, unless the maturity of any Designated
        Senior Indebtedness has been accelerated; or

        (c) the receipt of notice from those representatives of the holders of
        Designated Senior Indebtedness who gave the original notice of default
        stating that payments may be resumed.

     No new notice of default may be delivered unless and until 360 days have
elapsed since the effectiveness of the immediately prior notice of default. No
nonpayment default shall be the basis for a subsequent notice of default unless
that default will have been cured or waived for a period of not less than 90
days.

     As a result of the subordination provisions described above, in the event
of a bankruptcy, liquidation or reorganization of AMPAM, holders of these notes
may recover less ratably than creditors of AMPAM who are holders of Senior
Indebtedness.

     On a pro forma basis after giving effect to the sale of the notes and the
application of the estimated net proceeds therefrom, AMPAM and the guarantors
would have had, without duplication, approximately $3.5 million of Senior
Indebtedness and guarantor Senior Indebtedness outstanding as of December 31,
1998. The indenture will limit, but not prohibit, the incurrence by AMPAM of
additional Indebtedness which is senior to the notes and will prohibit the
incurrence by AMPAM of Indebtedness which is subordinated in right of payment to
any other indebtedness of AMPAM and senior in right of payment to the notes.

GUARANTEES

     The guarantors will jointly and severally guarantee our obligations under
these notes. The guarantees are full and unconditional. Each guarantee will be
subordinated to the prior payment in full of all guarantor Senior Indebtedness.
The obligations of each guarantor under its guarantee will be limited as
necessary to prevent that guarantee from constituting a fraudulent conveyance
under applicable law.

     Each guarantor may consolidate with or merge into or sell its assets to us
or another guarantor without limitation, or with other persons upon the terms
and conditions described in the indenture. See "-- Consolidation, Merger, Sale
of Assets, Etc." In the event all or substantially all of the assets or the
capital stock of a guarantor is sold or the guarantor is designated an
Unrestricted Subsidiary as allowed by the terms of the indenture, then the
guarantors guarantee will be automatically and unconditionally discharged and
released.

     Separate financial statements of the guarantors are not included in this
prospectus because the guarantors are jointly and severally liable with respect
to AMPAM's obligations under the notes, and the aggregate net assets, earnings
and equity of the guarantors and AMPAM are substantially equivalent to the net
assets, earnings and equity of AMPAM on a consolidated basis.

               immediately prior to the date of the proposed Restricted Payment
               for which consolidated financial statements are available (or, if
               the aggregate cumulative Consolidated Net Income of AMPAM for the
               period shall be a loss, minus 100% of the loss);

               (2) the aggregate net cash proceeds received by AMPAM as capital
               contributions to AMPAM after the Issue Date and which constitute

               into or exchanged for capital stock of AMPAM (other than
               Redeemable capital stock) to the extent the debt securities were
               originally sold for cash, plus the aggregate amount of cash

               Restricted Subsidiary after the Issue Date in accordance with "--
               Limitation on Designations of Unrestricted Subsidiaries" below,
               the fair market value of AMPAM's interest in the Subsidiary at
               the time of the redesignation. However, this amount shall not in
               any case exceed the Designation Amount with respect to the

<PAGE>   95

     For purposes of the preceding clause (C)(4), the value of the aggregate net
proceeds received by AMPAM upon the issuance of capital stock upon the exercise
of options, warrants or rights will be the net cash proceeds received upon the
issuance of the options, warrants or rights plus the incremental amount received
by AMPAM upon the exercise of the options, warrants or rights.

     None of the foregoing provisions will prohibit, so long as, in the case of
clauses (5) and (6) below, there is no default or event of default continuing:

        (1) the payment of any dividend or distribution within 60 days after the
        date of its declaration, if at the date of declaration this payment

        other shares of capital stock of AMPAM (other than Redeemable capital
        stock) to any person (other than to a Subsidiary of AMPAM); provided,
        however, that the net cash proceeds are excluded from clause (C) above;

        (3) any redemption, repurchase or other acquisition or retirement of
        Subordinated Indebtedness of AMPAM in exchange for, or out of the net
        cash proceeds of a substantially concurrent issue and sale of, (A)
        capital stock (other than redeemable capital stock) of AMPAM to any
        person (other than to a Subsidiary of AMPAM); provided, however, that
        any net cash proceeds of this type are excluded from clause (C) of the
        first paragraph of this covenant; or (B) other Subordinated Indebtedness
        of AMPAM which:

           - has an Average Life to Stated Maturity greater than the remaining
             Average Life to Stated Maturity of the notes; and

           - is subordinated to the notes to at least the same extent as the
             Subordinated Indebtedness so purchased, exchanged, redeemed,
             acquired or retired;

        (4) payments to purchase capital stock of AMPAM from management or

        of the Seller Preferred Stock in an aggregate amount not to exceed $1.4
        million in any one year;

                                       89
<PAGE>   96

        $16.2 million; provided, however, that AMPAM's Consolidated Fixed Charge

        (12) the payment of amounts constituting post-closing adjustments to the

        statements of AMPAM on the Issue Date, in each case, in accordance with
        the Acquisition Agreements as in effect on the Issue Date.

Any payments made pursuant to clauses (1), (4), (6), (10) and (11) of this
paragraph shall be taken into account in calculating the amount of Restricted
Payments made from and after the Issue Date.

     In computing Consolidated Net Income of AMPAM under clause (C)(1) of the
first paragraph of this covenant:

     - AMPAM shall use audited financial statements for the portions of the
       relevant period for which audited financial statements are available on
       the date of determination and unaudited financial statements and other
       current financial data based on the books and records of AMPAM for the
       remaining portion of that period; and

     - AMPAM shall be permitted to rely in good faith on the financial
       statements and other financial data derived from the books and records of
       AMPAM that are available on the date of determination.

If AMPAM makes a Restricted Payment which, at the time the Restricted Payment is
made would in the good faith determination of AMPAM be permitted under the
requirements of the indenture, that Restricted Payment shall be considered to
have been made in compliance with the indenture notwithstanding any subsequent
adjustments made in good faith to AMPAM's financial statements affecting
Consolidated Net Income of AMPAM for any period.

     LIMITATION ON LIENS. AMPAM will not, and will not permit any of its
Restricted Subsidiaries to, directly and indirectly, create, incur, assume or
suffer to exist any Liens of any kind securing Indebtedness upon any of its
property or assets, or any proceeds therefrom, unless the notes are equally and
ratably secured (except that Liens securing Subordinated Indebtedness shall be
expressly subordinate to Liens securing the notes to the same extent that
Subordinated Indebtedness is subordinate to the notes), except for:

     - Liens securing Senior Indebtedness and guarantor Senior Indebtedness;

     - Liens securing the notes;

     - Liens securing Indebtedness which is incurred to refinance Indebtedness
       which has been secured by a Lien (other than a Lien in favor of AMPAM or
       a Restricted Subsidiary) permitted under the indenture and which has been
       incurred in accordance with the provisions of the indenture; provided,
       however, that these Liens do not extend to or cover any property or
       assets of AMPAM or any of its Restricted Subsidiaries not securing the
       Indebtedness so refinanced; and

     - Permitted Liens.

     DISPOSITION OF PROCEEDS OF ASSET SALES. AMPAM will not, and will not permit
any of its Restricted Subsidiaries to, make any Asset Sale unless:

     - AMPAM or a Restricted Subsidiary, as the case may be, receives
       consideration at the time of the Asset Sale at least equal to the fair
       market value of the shares or assets sold or otherwise disposed of; and

     - at least 75% of the consideration in the Asset Sale, plus all other Asset
       Sales since the Issue Date on a cumulative basis, consists of cash or
       Cash Equivalents;

                                       90
<PAGE>   97

For purposes of this provision, the following shall be regarded as cash:

     - the amount of any Indebtedness (as shown on the most recent balance sheet
       of AMPAM or the Restricted Subsidiary) of AMPAM or a Restricted
       Subsidiary that is assumed by the transferee of the assets as a result of
       which AMPAM and its Restricted Subsidiaries are no longer liable thereon;
       and

     - any securities, notes or other obligations received by AMPAM or a
       Restricted Subsidiary from a transferee that are converted within 60 days
       into cash or Cash Equivalents (to the extent of the cash or Cash
       Equivalents received).

     Within 360 days after the receipt of any Net Cash Proceeds from an Asset
Sale, AMPAM or the Restricted Subsidiary may apply the Net Cash Proceeds at its
option:

     - to repay, and permanently reduce the commitments under Senior
       Indebtedness or Guarantor Senior Indebtedness;

     - to an investment in properties and assets that replace the properties and
       assets that were the subject of an Asset Sale;

     - to an investment in properties and assets that are used or useful in the
       business of AMPAM and its Restricted Subsidiaries conducted at that time;
       or

     - to an investment in capital stock of a person, the principal portion of
       whose assets qualify under either of the previous two points in
       businesses reasonably related thereto or in capital stock of a person,
       the principal portion of whose assets consist of these types property or
       assets.

     Any Net Cash Proceeds from any Asset Sale that are neither used to repay,
and permanently reduce the commitments under, Senior Indebtedness or Guarantor
Senior Indebtedness in accordance with their terms nor invested in replacement
assets within this 360-day period will constitute "Excess Proceeds" subject to
disposition as provided below. However, that any Net Cash Proceeds from any
Asset Sale which are used to repay Senior Indebtedness or Guarantor Senior
Indebtedness but are subsequently invested in replacement assets within this
360-day period will not constitute "Excess Proceeds."

     When the aggregate amount of Excess Proceeds equals or exceeds $10 million,
AMPAM shall make an offer to purchase, from all holders of the notes and any
then outstanding Pari Passu Indebtedness required to be repurchased or repaid on
a permanent basis in connection with an Asset Sale, an aggregate principal
amount of notes and any then outstanding Pari Passu Indebtedness equal to the
Excess Proceeds as follows:

     - (A) AMPAM shall make an offer to purchase from all holders of the notes
       in accordance with the procedures set forth in the indenture the maximum
       principal amount (expressed as a multiple of $1,000) of notes that may be
       purchased out of an amount equal to the product of the Excess Proceeds,
       multiplied by a fraction, the numerator of which is the outstanding
       principal amount of the notes and the denominator of which is the sum of
       the outstanding principal amount of the notes and Pari Passu
       Indebtedness, if any of all notes tendered, and (B) to the extent
       required by the Pari Passu Indebtedness and provided there is a permanent
       reduction in the principal amount of the Pari Passu Indebtedness, AMPAM
       shall make an offer to purchase Pari Passu Indebtedness in an amount
       equal to the excess of the Excess Proceeds over the Asset Sale offer
       amount;

     - The offer price for the notes shall be payable in cash in an amount equal
       to 100% of the principal amount of the notes tendered in connection with
       an Asset Sale Offer, plus accrued and unpaid interest, if any, to the
       date the Asset Sale Offer is consummated, in accordance with the
       procedures set forth in the indenture. To the extent that the aggregate
       Offered Price of the notes tendered in connection with an Asset Sale
       Offer is less than the Asset Sale Offer Amount relating thereto or the
       aggregate amount of the Pari Passu Indebtedness that is purchased or
       repaid in connection with the Pari Passu Offer is less than the Pari
       Passu Indebtedness Amount, AMPAM may use the Asset

                                       91
<PAGE>   98

       Sale Deficiency for general corporate purposes, subject to the
       limitations contained in the indenture; and

     - If the aggregate total price of notes validly tendered and not withdrawn
       by holders exceeds the amount offered, notes to be purchased will be
       selected on a pro rata basis. Upon completion of the offers described
       above, the amount of Excess Proceeds shall be reset to zero.

     AMPAM will comply with Rule 14e-1 under the Exchange Act and any other
securities laws and regulations, to the extent these laws and regulations are
applicable, in the event that an Asset Sale occurs and AMPAM is required to
purchase notes as described above, and any violation of the provisions of the
indenture relating to the offer described above occurring as a result of this
compliance shall not be considered a default or an event of default.

     LIMITATION ON ISSUANCES AND SALES OF RESTRICTED SUBSIDIARY STOCK. AMPAM
will not

     - permit any Restricted Subsidiary to issue any capital stock (other than
       to AMPAM or a Restricted Subsidiary); and

     - permit any Person (other than AMPAM and/or one or more Restricted
       Subsidiaries) to own any capital stock of any Restricted Subsidiary.

This covenant shall not prohibit:

     - the issuance and sale of all, but not less than all, of the issued and
       outstanding capital stock of any Restricted Subsidiary owned by AMPAM or
       any of its Restricted Subsidiaries in compliance with the other
       provisions of the indenture; or

     - the ownership by directors of directors' qualifying shares or the
       ownership by foreign nationals of capital stock of any Restricted
       Subsidiary, to the extent mandated by applicable law.

     LIMITATION ON TRANSACTIONS WITH AFFILIATES. AMPAM will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, enter into
any transaction or series of related transactions (including, without
limitation, the sale, transfer, disposition, purchase, exchange or lease of
assets, property or services) with, or for the benefit of, any of its
Affiliates, except:

        (a) on terms that are no less favorable to AMPAM or the Restricted
        Subsidiary, as the case may be, than those which could have been
        obtained at the time in a comparable transaction or series of related
        transactions from persons who are not Affiliates of AMPAM,

        (b) with respect to a transaction or series of related transactions
        involving aggregate payments or value equal to or greater than $5
        million, AMPAM shall have delivered an officers' certificate to the
        trustee certifying that this transaction or transactions comply with the
        preceding clause (a) and have been approved by the Disinterested Members
        of the Board of Directors of AMPAM; provided, however that AMPAM may, if
        there are no Disinterested Members of the Board of Directors or at its
        option, obtain and deliver to the trustee the written opinion referred
        to in clause (c) below in lieu of an officers' certificate and

        (c) with respect to a transaction or series of related transactions
        involving aggregate payments or value equal to or greater than $10
        million, AMPAM shall have delivered to the trustee the officers'
        certificate referred to in clause (b) which includes a certification
        that this transaction or transactions have been approved by a majority
        of the Disinterested Members of the Board of Directors of AMPAM or, in
        the event there are no Disinterested Members of the Board of Directors,
        that AMPAM has obtained a written opinion from an independent nationally
        recognized investment banking firm, accounting firm or appraisal firm,
        in each case specializing or having a specialty in the type and subject
        matter of the transaction or series of transactions at issue, which
        opinion shall be to the effect set forth in clause (a) above or shall
        state that SUCH transaction or series of related transactions is fair
        from a financial point of view to AMPAM or the Restricted Subsidiary.

                                       92
<PAGE>   99

     - customary directors' fees, indemnification and similar arrangements,
       consulting fees, employee salaries, bonuses or employment agreements,

       Redeemable capital stock) of AMPAM.

     LIMITATION ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
SUBSIDIARIES. AMPAM will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to:

     - pay dividends, in cash or otherwise, or make any other distributions on
       or in respect of its capital stock to AMPAM or any other Restricted
       Subsidiary,

     - pay any Indebtedness owed to AMPAM or any other Restricted Subsidiary,

     - make loans or advances to AMPAM or any other Restricted Subsidiary,

     - transfer any of its properties or assets to AMPAM or any other Restricted
       Subsidiary or

     - guarantee any Indebtedness of AMPAM or any other Restricted Subsidiary.

However, the following encumbrances or restrictions are allowed:

     - those existing under or by reason of applicable law or any applicable
       rule, regulation or order;

     - customary nonassignment provisions of any contract or any lease governing
       a leasehold interest of AMPAM or any Restricted Subsidiary;

     - customary restrictions on transfers of property subject to a Lien
       permitted under the indenture (including purchase money Liens permitted
       under the indenture);

     - any agreement or other instrument of a person acquired by AMPAM or any
       Restricted Subsidiary in existence at the time of the acquisition (but
       not created in contemplation of such an acquisition), which encumbrance
       or restriction is not applicable to any person, or the properties or
       assets of any person, other than the person, or the property or assets of
       the person, so acquired;

     - an agreement entered into for the sale or disposition of capital stock or
       assets of a Restricted Subsidiary or an agreement entered into for the
       sale of specified assets (in either case, so long as the encumbrance or
       restriction, by its terms, terminates on the earlier of the termination
       of the agreement or the consummation of the agreement and so long as the
       restriction applies only to the capital stock or assets to be sold);

                                       93
<PAGE>   100

     - any agreement in effect on the Issue Date (including, without limitation,
       the credit facility);

     - those existing under or by reason of the indenture and the guarantees;
       and

     - any agreement that amends, extends, refinances, renews or replaces any
       agreement described in the foregoing clauses; provided, however, that the
       terms and conditions of any agreement of this type are not materially
       less favorable to the holders of the notes with respect to these
       encumbrances or restrictions than those under the agreement amended,
       extended, refinanced, renewed or replaced.

     LIMITATION ON DESIGNATIONS OF UNRESTRICTED SUBSIDIARIES. AMPAM may
designate after the Issue Date any Restricted Subsidiary as an "Unrestricted
Subsidiary" under the indenture (a "Designation") only if:

     - no default shall have occurred and be continuing at the time of or after
       giving effect to a Designation;

     - AMPAM would be permitted to make an Investment (other than a Permitted
       Investment covered by clause (x) of that definition) at the time of the
       Designation pursuant to the first paragraph of "-- Limitation on
       Restricted Payments" above in an amount (the "Designation Amount") equal
       to the fair market value of AMPAM's interest in the Subsidiary on that
       date; and

     - AMPAM would be permitted under the indenture to incur $1.00 of additional
       Indebtedness (other than Permitted Indebtedness) pursuant to the covenant
       described under "-- Limitation on Indebtedness" at the time of the
       Designation (assuming the effectiveness of the Designation).

     In the event of any Designation of this type, AMPAM shall be regarded as
having made an Investment constituting a Restricted Payment under the covenant
"-- Limitation on Restricted Payments" for all purposes of the indenture in the
Designation Amount.

     AMPAM shall not, and shall not cause or permit any Restricted Subsidiary
to, at any time:

     - provide credit support for or subject any of its property or assets
       (other than the capital stock of any Unrestricted Subsidiary) to the
       satisfaction of, any Indebtedness of any Unrestricted Subsidiary;

     - be directly or indirectly liable for any Indebtedness of any Unrestricted
       Subsidiary; or

     - be directly or indirectly liable for any Indebtedness which provides that
       the holder of that Indebtedness may (upon notice, lapse of time or both)
       declare a default thereon or cause payment to be accelerated or payable
       prior to its final Stated Maturity upon the occurrence of a default with
       respect to any Indebtedness of any Unrestricted Subsidiary.

          The Designation of any Subsidiary as an Unrestricted Subsidiary shall
     automatically include the Designation of all Subsidiaries of that
     Subsidiary as Unrestricted Subsidiaries.

     AMPAM may revoke any Designation of a Subsidiary as an Unrestricted
Subsidiary (a "Revocation") if:

     - no default shall have occurred and be continuing at the time of and after
       giving effect to the Revocation; and

     - all Liens and Indebtedness of the Unrestricted Subsidiary outstanding
       immediately following the Revocation would, if incurred at that time,
       have been permitted to be incurred under the indenture.

     All Designations and Revocations must be evidenced by Board Resolutions of
AMPAM delivered to the trustee certifying compliance with the foregoing
provisions.

     LIMITATION ON THE ISSUANCE OF SUBORDINATED INDEBTEDNESS. AMPAM will not,
and will not permit any guarantor to, directly or indirectly, incur any
Indebtedness (including Acquired Indebtedness) that is expressly subordinate or
junior in right of payment to any other Indebtedness of AMPAM or that
                                       94
<PAGE>   101

guarantor and senior in right of payment to the notes or the guarantee of that
guarantor, as the case may be.

     ADDITIONAL SUBSIDIARY GUARANTEES. If AMPAM or any of its Restricted
Subsidiaries acquires, creates or designates another Restricted Subsidiary
organized under the laws of the United States or any of its possessions or
territories, any State of the United States or the District of Columbia, then
this newly acquired, created or designated Restricted Subsidiary shall, within
30 days after the date of its acquisition, creation or designation, whichever is
later, execute and deliver to the trustee a supplemental indenture in form
reasonably satisfactory to the trustee through which that Subsidiary shall
unconditionally guarantee (on a senior subordinated basis) all of AMPAM's
obligations under the notes and the indenture on the terms set forth in the
indenture; provided, however, that this Restricted Subsidiary shall not be
obligated to become a guarantor in the manner set forth above if this Restricted
Subsidiary is not, either individually or when considered in the aggregate with
all other Restricted Subsidiaries that are not guarantors, a Significant
Subsidiary. Thereafter, this Restricted Subsidiary shall be a guarantor for all
purposes of the indenture. Any Restricted Subsidiary that is not a guarantor
shall become a guarantor in the manner provided above within 30 days of that
time as it becomes, either individually or when considered in the aggregate with
all other Restricted Subsidiaries that are not guarantors, a Significant
Subsidiary. AMPAM at its option may also cause any other Restricted Subsidiary
to so become a guarantor.

     REPORTING REQUIREMENTS. For so long as the notes are outstanding, whether
or not AMPAM is subject to Section 13(a) or 15(d) of the Exchange Act, or any
successor provisions, AMPAM shall file with the SEC the annual reports,
quarterly reports and other documents which AMPAM would have been required to
file with the SEC under Section 13(a) or 15(d) or any successor provisions if
AMPAM were so subject, these documents to be filed with the SEC on or prior to
the respective dates by which AMPAM would have been required so to file these
documents if AMPAM were so subject. AMPAM shall also in any event within 15 days
after each required filing date file with the trustee, copies of the annual
reports, quarterly reports and other documents which AMPAM would be required to
file with the SEC if the notes were then registered under the Exchange Act and
to make this information available to holders of notes upon request. In
addition, if AMPAM is not subject to the reporting requirements of the Exchange
Act, for so long as any notes remain outstanding, AMPAM will furnish to the
holders of notes and prospective investors, upon their request, the information
required to be delivered under Rule 144A(d)(4) under the Securities Act.

CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.

     AMPAM will not, in any transaction or series of transactions, merge or
consolidate with or into, or sell, assign, convey, transfer, lease or otherwise
dispose of all or substantially all of its properties and assets to, any person
or persons, and AMPAM will not permit any of its Restricted Subsidiaries to
enter into any transaction of this type or series of transactions if that
transaction or series of transactions, in the aggregate, would result in a sale,
assignment, conveyance, transfer, lease or other disposition of all or
substantially all of the properties and assets of AMPAM and its Restricted
Subsidiaries, on a consolidated basis, to any other person or persons, unless:

     - either (1) if the transaction or series of transactions is a merger or
       consolidation, AMPAM or the Restricted Subsidiary, as the case may be,
       shall be the surviving person of the merger or consolidation, or (2) the
       person formed by the consolidation or into which AMPAM or the Restricted
       Subsidiary, as the case may be, is merged or to which the properties and
       assets of AMPAM or the Restricted Subsidiary, as the case may be, are
       disposed of shall be a corporation organized and existing under the laws
       of the United States of America, any state or the District of Columbia
       and shall expressly assume by a supplemental indenture executed and
       delivered to the trustee, in form satisfactory to the trustee, all the
       obligations of AMPAM under the notes, the indenture and the registration
       rights agreement, and in each case, the indenture shall remain in full
       force and effect;

                                       95
<PAGE>   102

     - immediately after giving effect to the transaction or series of
       transactions on a pro forma basis, no default or event of default shall
       have occurred and be continuing; and

     - except in the case of any merger of AMPAM with any Restricted Subsidiary
       or any merger of guarantors, AMPAM or the surviving entity, as the case
       may be, after giving effect to the transaction or series of transactions
       on a pro forma basis on the assumption that the transaction or
       transactions had occurred on the first day of the period of four fiscal
       quarters ending immediately prior to the consummation of the transaction
       or transactions, with the appropriate adjustments with respect to the
       transaction or transactions being included in the pro forma calculation,
       could incur $1.00 of additional Indebtedness in accordance with the
       "Limitation on Indebtedness" covenant described above.

     Upon any consolidation, merger or any sale, assignment, conveyance,
transfer, lease or other disposition in accordance with the immediately
preceding paragraphs, the successor person formed by the consolidation or into
which AMPAM or a Restricted Subsidiary, as the case may be, is merged or the
successor person to which the sale, assignment, conveyance, transfer, lease or
other disposition is made shall succeed to, and be substituted for, and may
exercise every right and power of AMPAM under the notes, the indenture and/or
the registration rights agreement, as the case may be, with the same effect as
if the successor had been named as AMPAM in the notes, the indenture and/or the
registration rights agreement, as the case may be, and, except in the case of a
lease, AMPAM or the Restricted Subsidiary shall be released and discharged from
its obligations under the notes and the indenture.

     For all purposes of the indenture and the notes (including, without
limitation, the provision of this covenant and the covenants described in
"-- Material Covenants -- Limitation on Indebtedness," "-- Limitation on
Restricted Payments," and "-- Limitation on Liens"), Subsidiaries of any
surviving person shall, upon the transaction or series of related transactions,
become Restricted Subsidiaries unless and until designated Unrestricted
Subsidiaries under and in accordance with "-- Limitation on Designations of
Unrestricted Subsidiaries" and all Indebtedness, and all Liens on property or
assets, of AMPAM and the Restricted Subsidiaries in existence immediately after
the transaction or series of related transactions will be considered to have
been incurred upon the transaction or series of related transactions.

EVENTS OF DEFAULT

     The following are "events of default" under the indenture:

        (1) default in the payment of the principal of or premium, if any, when
        due and payable, on any of the notes (at Stated Maturity, upon optional
        redemption, required purchase or otherwise) (whether or not prohibited

        (2) default in the payment of an installment of interest on any of the

        clause (1), (2) or (4)) and this default or breach shall continue for a
        period of 30 days after written notice has been given, by certified
        mail,

        - to AMPAM by the trustee or

        - to AMPAM and the trustee by the holders of at least 25% in aggregate
          principal amount of the outstanding notes; or

        (5) default or defaults under one or more agreements, instruments,
        mortgages, bonds, debentures or other evidences of Indebtedness under
        which AMPAM or any Restricted Subsidiary then has outstanding
        Indebtedness in excess of $10 million, individually or in the aggregate,
        and

        - the default or defaults include a failure to make a payment of
          principal,

        - the Indebtedness is already due and payable in full or

        - the default or defaults have resulted in the acceleration of the
          maturity of this Indebtedness;

        provided, that if any default described above is cured or waived or any
        acceleration rescinded, or the Indebtedness is repaid, within a period
        of 10 days from the continuation of the default beyond the applicable
        grace period or the occurrence of the acceleration, as the case may be,
        the event of default under the indenture and any consequential
        acceleration of the notes shall be automatically rescinded, so long as
        the rescission does not conflict with any judgment or decree; or

        (6) one or more judgments, orders or decrees of any court or regulatory
        or administrative agency of competent jurisdiction for the payment of

        by the insurer or which has been determined to be applicable by a final
        nonappealable determination by a court of competent jurisdiction), shall
        be entered against AMPAM or any Restricted Subsidiary or any of their
        respective properties and shall not be discharged and there shall have
        been a period of 60 days after the date on which any period for appeal

        order or decree shall not be in effect; or

        (7) the entry of a decree or order by a court having jurisdiction in the
        premises (A) for relief in respect of AMPAM or any Significant
        Subsidiary or one or more Restricted Subsidiaries that, taken together,

        proceeding under the Federal Bankruptcy Code or any other federal, state
        or foreign bankruptcy, insolvency, reorganization or similar law or (B)

        reorganization, arrangement, adjustment or composition of or in respect
        of AMPAM or any Significant Subsidiary or one or more Restricted

        properties, or ordering the winding up or liquidation of any of their
        affairs, and the continuance of any decree or order unstayed and in

        Federal Bankruptcy Code or any other similar federal, state or foreign
        law or any other case or proceedings to be adjudicated a bankrupt or
        insolvent, or the consent by AMPAM or any Significant Subsidiary or one
        or more Restricted Subsidiaries that, taken together, would constitute a
        Significant Subsidiary to the entry of a decree or order for relief in
        respect of AMPAM or a Significant Subsidiary or group of Restricted
        Subsidiaries in any involuntary case or proceeding under the Federal
        Bankruptcy Code or any other similar federal, state or foreign law or to
        the institution of bankruptcy or insolvency proceedings against AMPAM or
        a Significant Subsidiary or group of Restricted Subsidiaries, or the

        trustee or sequestrator (or other similar official) of any of AMPAM or
        any Significant Subsidiary or one or more Restricted Subsidiaries that,
        taken together, would constitute a Significant Subsidiary or of any
        substantial part of its property, or the making by it of an assignment
        for the benefit of creditors, or the admission by it in writing of its
        inability to pay its debts generally as they become due or the taking of
        corporate action by AMPAM or any Significant Subsidiary or one or more
        Restricted Subsidiaries that, taken together, would constitute a
        Significant Subsidiary in furtherance of any action of this type; or

        (9) any of the Guarantees of any Significant Subsidiary or one or more
        Restricted Subsidiaries that, taken together, would constitute a
        Significant Subsidiary ceases to be in full force and effect or any of
        these Guarantees is declared to be null and void and unenforceable or
        any of these Guarantees is found to be invalid or any guarantors denies
        its liability under its Guarantee, other than by reason of release of
        the guarantor in accordance with the terms of the indenture.

     If an event of default (other than those covered by clause (7) or (8)
above) shall occur and be continuing, the trustee, by notice to AMPAM, or the
holders of at least 25% in aggregate principal amount of the notes then
outstanding, by notice to the trustee and AMPAM, may declare the principal of,
premium, if any, and accrued and unpaid interest, if any, on all of the
outstanding notes due and payable immediately on which declaration, all amounts
payable in respect of the notes shall be due and payable. If an event of default
specified in clause (7) or (8) above occurs and is continuing, then the
principal of, premium, if any, and accrued and unpaid interest, if any, on all
the outstanding notes shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the trustee or any holder of
notes.

     After a declaration of acceleration under the indenture, but before a
judgment or decree for payment of the money due has been obtained by the
trustee, the holders of a majority in aggregate principal amount of the
outstanding notes, by written notice to AMPAM and the trustee, may rescind the
declaration if:

     - AMPAM or any guarantor has paid or deposited with the trustee a sum
       sufficient to pay

        (a) all sums paid or advanced by the trustee under the indenture and the
            reasonable compensation, expenses, disbursements and advances of the
            trustee, its agents and counsel,

        (b) all overdue interest on all notes,

        (c) the principal of and premium, if any, on any notes which have become
            due otherwise than by the declaration of acceleration and interest
            thereon at the rate borne by the notes, and

        (d) to the extent that payment of interest is lawful, interest upon
            overdue interest and overdue principal at the rate borne by the
            notes which has become due otherwise than by a declaration of
            acceleration;

     - the rescission would not conflict with any judgment or decree of a court
       of competent jurisdiction; and

     - all events of default, other than the non-payment of principal of,
       premium, if any, and interest on the notes that has become due solely by
       a declaration of acceleration, have been cured or waived.

     No holder of any of the notes will have any right to institute any
proceeding with respect to the indenture or any remedy thereunder, unless the
holders of at least 25% in aggregate principal amount of the outstanding notes
have made written request, and offered reasonable indemnity, to the trustee to
institute a proceeding of this type as trustee under the notes and the
indenture, the trustee has failed to institute a proceeding of this type within
45 days after receipt of notice and the trustee, within the 45-day period, has
not received directions inconsistent with the written request by holders of a
majority in aggregate principal amount of the outstanding notes. Such
limitations will not apply, however, to a suit

                                       98
<PAGE>   105

instituted by a holder of a note for the enforcement of the payment of the
principal of, premium, if any, or interest on the note on or after the
respective due dates expressed in the note.

     During the existence of an event of default, the trustee will be required
to exercise the rights and powers vested in it under the indenture and use the
same degree of care and skill in its exercise of these rights as a prudent
person would exercise under the circumstances in the conduct of that person's
own affairs. Subject to the provisions of the indenture relating to the duties
of the trustee, in case an event of default shall occur and be continuing, the
trustee under the indenture will not be under any obligation to exercise any of
its rights or powers under the indenture at the request or direction of any of
the holder unless the holders shall have offered to the trustee reasonable
security or indemnity. Subject to provisions concerning the rights of the
trustee, the holders of a majority in aggregate principal amount of the
outstanding notes will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the trustee, or exercising
any trust or power conferred on the trustee under the indenture.

     If a default or an event of default occurs and is continuing and is known
to the trustee, the trustee shall mail to each holder of the notes notice of the
default or event of default within 30 days after obtaining knowledge of the
default or event of default. Except in the case of a default or an event of
default in payment of principal of premium, if any, or interest on any notes,
the trustee may withhold the notice to the holders of these notes if a committee
of its trust officers in good faith determines that withholding the notice is in
the interest of the Noteholders.

     AMPAM must furnish to the trustee annual and quarterly statements as to the
performance by AMPAM of its obligations under the indenture and as to any
default in this performance. AMPAM also will be required to notify the trustee
within five business days of any event which is, or after notice or lapse of
time or both would become, an event of default.

NO LIABILITY FOR CERTAIN PERSONS

     No director, officer, employee or stockholder of AMPAM, nor any director,
officer or employee of any guarantor, as such, will have any liability for any
obligations of AMPAM or any guarantor under the notes, the guarantees or the
indenture based on, in respect of, or by reason of the obligations described or
their creation. Each holder by accepting a Note waives and releases all
liability of this type. The foregoing waiver and release are an integral part of
the consideration or the issuance of the notes. Such waiver may not be effective
to waive liabilities under the federal securities laws.

LEGAL DEFEASANCE OR COVENANT DEFEASANCE OF INDENTURE

     AMPAM may, at its option and at any time, terminate the obligations of
AMPAM and the guarantors with respect to the outstanding notes ("Legal
Defeasance") to the extent set forth below. Such Legal Defeasance means that
AMPAM shall be considered to have paid and discharged the entire Indebtedness
represented by the outstanding notes, except for:

     - the rights of holders of outstanding notes to receive payment in respect
       of the principal of, premium, if any, and interest on these notes when
       payments are due;

     - AMPAM's obligations to issue temporary notes, register the transfer or
       exchange of any notes, replace mutilated, destroyed, lost or stolen notes
       and maintain an office or agency for payments in respect of the notes;

     - the rights, powers, trusts, duties and immunities of the trustee; and

     - the Legal Defeasance provisions of the indenture. In addition, AMPAM may,
       at its option and at any time, elect to terminate the obligations of
       AMPAM and the guarantors with respect to covenants in the indenture, some
       of which are described under "-- Material Covenants" above, and any
       subsequent failure to comply with these obligations shall not constitute
       a default or an event of default with respect to the notes.

                                       99
<PAGE>   106

     In order to exercise either Legal Defeasance or Covenant Defeasance:

     - AMPAM shall have delivered to the trustee an opinion of counsel to the
       effect that the holders of the outstanding notes will not recognize

       generally;

     - AMPAM shall have delivered to the trustee an officers' certificate
       stating that the deposit was not made by AMPAM with the intent of
       preferring the holders of the notes over the other creditors of AMPAM
       with the intent of hindering, delaying or defrauding creditors of AMPAM
       or others;

     - no event or condition shall exist that would prevent AMPAM from making

       the date of the deposit; and

AMENDMENTS AND WAIVERS

     From time to time, AMPAM and the guarantors, when authorized by a

or sale of all or substantially all of AMPAM's assets, or to make any change
that would provide any additional rights or benefits to the holders of the
notes, in each case, as long as any change of this type does not adversely
affect the rights of any holder of notes. Other amendments and modifications of
the indenture or the notes may be made by AMPAM, the guarantors and the trustee
with the consent of the holders of not less than a majority of the aggregate

     The holders of not less than a majority in aggregate principal amount of
the outstanding notes may on behalf of the holders of all the notes waive (1)
compliance by AMPAM with restrictive provisions of the indenture and (2) any
past defaults under the indenture, except a default in the payment of the
principal of, premium, if any, or interest on any Note, or in respect of a
covenant or provision which under the indenture cannot be modified or amended
without the consent of the holder of each Note outstanding.

THE TRUSTEE

     The indenture provides that, except during the continuance of an event of
default, the trustee thereunder will perform only those duties as are
specifically set forth in the indenture. If an event of default has occurred and
is continuing, the trustee will exercise the rights and powers vested in the
trustee under the indenture and use the same degree of care and skill in its
exercise as a prudent person would exercise under the circumstances in the
conduct of a person's own affairs.

     The indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the trustee thereunder,
should it become a creditor of AMPAM, to obtain payment of claims in cases or to
realize on property received by it in respect of any claims of the type
previously described, as security or otherwise. The trustee may engage in other
transactions; provided, however, that if it acquires any conflicting interest
(as defined in the Trust Indenture Act), it must eliminate this conflict or
resign.

     State Street Bank and Trust Company, is the trustee under the indenture.

Consolidated Cash Flow Available for Fixed Charges of this person for the four

Fixed Charge Coverage Ratio (this four full fiscal quarter period referred to as
the "Four Quarter Period") to the aggregate amount of Consolidated Fixed Charges
of this person for this Four Quarter Period. For purposes of making the
computation referred to above, Consolidated Cash Flow Average for Fixed Charges
and Consolidated Fixed Charges shall be calculated giving pro forma effect (in a
manner consistent with Rule 11-02 of Regulation S-X to the following events
(without duplication):

     - any Asset Sale or Asset Acquisition occurring since the first day of the
       Four Quarter Period (including to the date of calculation) as if the
       acquisition or disposition occurred at the beginning of the Four Quarter
       Period (including giving effect to (A) the amount of any reduction in

       general, administrative or overhead costs of the entity involved in any
       Asset Sale or Asset Acquisition of this type);

       Consolidated Fixed Charge Coverage Ratio and (if applicable) the
       application of the net proceeds therefrom, including to refinance other
       indebtedness, as if the Indebtedness were incurred at the beginning of
       the Four Quarter Period;

     - the incurrence, repayment or retirement of any other Indebtedness by
       AMPAM and its Restricted Subsidiaries since the first day of the Four
       Quarter Period and prior to the date of making this calculation as if the
       Indebtedness or obligations were incurred, prepaid or retired at the
       beginning of the Four Quarter Period (except that in making this
       computation, the amount of Indebtedness under any revolving credit

       Consolidated Fixed Charges will not be obligations of the referent person
       or any of its Restricted Subsidiaries following the Transaction Date.

In calculating Consolidated Fixed Charges for purposes of determining the
denominator (but not the numerator) of the Consolidated Fixed Charge Coverage
Ratio,

     - interest on outstanding Indebtedness determined on a fluctuating basis as
       of the Transaction Date and which will continue to be so determined
       thereafter shall be considered to have accrued at a
                                       105
<PAGE>   112

       fixed rate per annum equal to the rate of interest on this Indebtedness
       in effect on the Transaction Date; and

     - if interest on any Indebtedness actually incurred on the Transaction Date
       may optionally be determined at an interest rate based upon a factor of a
       prime or similar rate, a Eurocurrency interbank offered rate, or other
       rates, then the interest rate in effect on the Transaction Date will be
       considered to have been in effect during the Four Quarter Period. If this
       person or any of its Restricted Subsidiaries directly or indirectly
       guarantees Indebtedness of a third person, the above provisions shall
       give effect to the incurrence of this guaranteed Indebtedness as if the
       person or the Subsidiary had directly incurred or otherwise assumed this
       guaranteed Indebtedness.

     "Consolidated Fixed Charges" means, with respect to any person for any
period, the sum of, without duplication, the amounts for this period of:

       its Restricted Subsidiaries on a consolidated basis (other than dividends
       or distributions paid solely in shares of capital stock (other than
       Redeemable capital stock)) times (b) a fraction, the numerator of which
       is one and the denominator of which is one minus the then current
       effective consolidated federal, state and local tax rate of the person,
       expressed as a decimal.

     "Consolidated Income Tax Expense" means, with respect to any person for any
period, the provision for federal, state, local and foreign income taxes of this

period, without duplication, the sum of:

       including, without limitation;

        (a) an amortization of debt discount, capitalized debt issuance costs
        and original issue discount,

        (b) the net cost under Interest Rate Protection Obligations (including
        any amortization of discounts);

        (c) the interest portion of any deferred payment obligation;

        respect to letters of credit, bankers' acceptance financing or similar

     - the interest component of Capitalized Lease Obligations paid, accrued
       and/or scheduled to be paid or accrued by this person and its Restricted

period, the consolidated net income (or loss) of that person and its Restricted

BOOK-ENTRY; DELIVERY AND FORM

     Notes offered and sold to QIBs in reliance on Rule 144A under the
Securities Act will be represented by a single, permanent global note in
definitive, fully registered book-entry form (the "Global Security")

                                       115
<PAGE>   122

which will be registered in the name of a nominee of DTC and deposited on behalf
of purchasers of the notes represented thereby with a custodian for DTC for
credit to the respective accounts of the purchasers (or to such other accounts
as they may direct) at DTC.

     THE GLOBAL SECURITY. AMPAM expects that, under procedures established by
DTC, ownership of the notes will be shown on, and the transfer of ownership of
the notes will be effected only through, records maintained by DTC or its
nominee (with respect to interests of Participants (as defined below)) and the
records of Participants (with respect to interests of persons other than
Participants). Such accounts initially will be designated by or on behalf of the
Initial Purchasers and ownership of beneficial interests in the Global Security
will be limited to persons who have accounts with DTC ("Participants") or
persons who hold interests through Participants. QIBs may hold their interests
in the Global Security directly through DTC if they are Participants in this
system, or indirectly through organizations which are Participants in this
system.

     So long as DTC or its nominee is the registered owner or holder of any of
the notes, DTC or its nominee will be considered the sole owner or holder of the
notes represented by the Global Security for all purposes under the indenture
and under the notes represented thereby. No beneficial owner of an interest in
the Global Security will be able to transfer the interest except in accordance
with the applicable procedures of DTC in addition to those provided for under
the indenture. The laws of some states require that some persons take physical
delivery in definitive form of securities that they own. Consequently, the
ability to transfer beneficial interest in the Global Security to the persons
will be limited to that extent. Because DTC can act only on behalf of
Participants, which in turn act on behalf of Indirect Participants (as defined
in this prospectus), the ability of a person having beneficial interests in the
Global Security to pledge these interests to persons or entities that do not
participate in the DTC system, or otherwise take actions in respect of the
interests, may be affected by the lack of a physical certificate evidencing
these interests.

     Payments of the principal of, premium, if any, and interest on the notes
represented by the Global Security will be made to DTC or its nominee, as the
case may be, as the registered owner of the Global Security. None of AMPAM, the
trustee or any paying agent under the indenture will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in the Global Security or for maintaining,
supervising or reviewing any records relating to the beneficial ownership
interest.

     AMPAM expects that DTC or its nominee, upon receipt of any payment of the
principal of, premium, if any, and interest on the notes represented by the
Global Security, will credit Participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the Global Security as
shown in the records of DTC or its nominee. AMPAM also expects that payments by
Participants to owners of beneficial interests in the Global Security held
through Participants will be governed by standing instructions and customary
practice as is now the case with securities held for the accounts of customers
registered in the names of nominees for these customers. Such payment will be
the responsibility of the Participants.

     DTC has advised AMPAM that DTC will take any action permitted to be taken
by a holder of notes (including the presentation of notes for exchange as
described below) only at the direction of one or more Participants to whose
account the DTC interests in the Global Security are credited and only in
respect of the aggregate principal amount as to which the Participant or
Participants has or have given direction.

     DTC has advised AMPAM as follows: DTC is a limited purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "clearing agency" registered under the provisions of
Section 17A of the Exchange Act. DTC was created to hold securities for its
Participants and facilitate the clearance and settlement of securities
transactions between Participants through electronic book-entry changes in
accounts of its Participants, thereby eliminating the need for physical movement
of certificates. Participants include securities brokers and dealers, banks,
trust companies and clearing corporations and various other organizations.
Indirect access to the DTC system is available to others like banks, brokers,
                                       116
<PAGE>   123

dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly ("Indirect
Participants").

     Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the Global Security among Participants of
DTC, is it under no obligation to perform these procedures, and these procedures
may be discontinued at any time. Neither AMPAM nor the trustee will have any
responsibility for the performance by DTC or its direct or indirect participants
of their obligations under the rules and procedures governing their operations.

     CERTIFICATED SECURITIES. Interests in the Global Security will be exchanged
for Certificated Securities if DTC notifies AMPAM that it is unwilling or unable
to continue as depositary for the Global Security, or DTC ceases to be a
"Clearing Agency" registered under the Exchange Act, and a successor depositary
is not appointed by AMPAM within 90 days. Upon the occurrence of any of the
events described in the preceding sentence, AMPAM will cause the appropriate
Certificated Securities to be delivered.

                                       117
<PAGE>   124

                              REGISTRATION RIGHTS

     AMPAM has entered into a registration rights agreement with the initial
purchasers under which AMPAM and the guarantors have agreed, for the benefit of
the holders of the notes, at AMPAM's cost, to use their reasonable best efforts:

     - to file with the SEC the registration statement of which this prospectus
       is a part related to the exchange offer of the exchange notes within 60
       days after the Issue Date;

     - to cause this exchange offer registration statement to be declared
       effective under the Securities Act within 150 days of the Issue Date;

     - to keep this exchange offer registration statement effective until the
       closing of the exchange offer; and

     - to cause this exchange offer to be completed within 180 days of the Issue
       Date.

     Under the registration rights agreement, AMPAM is required to allow
participating broker-dealers to use the prospectus contained in the exchange
offer registration statement (subject to "black out" periods) following the
exchange offer, in connection with the resale of exchange notes received in
exchange for notes acquired by those participating broker-dealers for their own
account as a result of market-making or other trading activities.

     The registration rights agreement shall be governed by, and construed
under, the laws of the State of New York. If you have further questions about
registration rights, you should refer to the registration rights agreement, a
copy of which is available upon request to AMPAM. The registration rights
agreement is also attached as an exhibit to this registration statement. In
addition, the information described above concerning interpretations of and
positions taken by the staff of the SEC is not intended to constitute legal
advice, and prospective investors should consult their own advisors on these
matters.

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives exchange notes for its own account in the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of the exchange notes. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of exchange notes received in exchange for existing notes where the
existing notes were acquired as a result of market-making activities or other
trading activities.

     AMPAM will not receive any proceeds from any sale of exchange notes by
broker-dealers. Exchange notes received by broker-dealers for their own account
in the exchange offer may be sold from time to time in one or more transactions
in the over-the-counter market, in negotiated transactions, through the writing
of options on the exchange notes or a combination of these methods of resale, at
market prices prevailing at the time of resale, at prices related to those
prevailing market prices or at negotiated prices. Any resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any broker-dealer or
the purchasers of any exchange notes. Any broker-dealer that resells exchange
notes that were received by it for its own account in the exchange offer and any
broker or dealer that participates in a distribution of the exchange notes may
be an "underwriter" within the meaning of the Securities Act and any profit on
any resale of exchange notes and any commission or concessions received by any
person may be considered underwriting compensation under the Securities Act. The
letter of transmittal states that, by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not be regarded as an admission
that it is an "underwriter," within the meaning of the Securities Act.

     AMPAM has agreed to pay all expenses incident to the exchange offer
(including the expenses of one counsel for the holders of the notes), other than
commissions or concessions of any broker-dealers, and will indemnify the holders
of the notes (including any broker-dealers) against some liabilities, including
liabilities under the Securities Act.

          AMERICAN PLUMBING & MECHANICAL, INC. AND FOUNDING COMPANIES
               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
                             BASIS OF PRESENTATION

     The following unaudited pro forma combined financial statements give effect
to (a) the acquisitions by American Plumbing & Mechanical, Inc. (AMPAM), of the
outstanding capital stock of Christianson, RCR, Teepe's, Keith Riggs, Croson
Ohio, Croson Florida, Power, Nelson, Sherwood and Miller, and related
transactions, and (b) the issuance of the 11 5/8% Senior Subordinated Notes due
2008 and application of the net proceeds therefrom. The acquisitions occurred on
April 1, 1999 and have been accounted for using the purchase method of
accounting. Christianson has been reflected as the accounting acquiror for
financial statement presentation purposes.

     The unaudited pro forma combined balance sheet gives effect to the
acquisitions and related transactions, and the issuance of the notes, as if they
had occurred on March 31, 1999. The unaudited pro forma combined statements of
operations give effect to these transactions as if they had occurred on January
1 of the respective period presented.

     These pro forma combined financial statements should be read in conjunction
with the financial statements of each of the Founding Companies included
elsewhere herein.

     AMPAM has preliminarily analyzed the savings that it expects to be realized
from reductions in salaries, bonuses and certain benefits, including lease
payments to the owners. To the extent the owners of the founding companies have
contractually agreed to prospective changes in salary, bonuses, benefits and
lease payments, these changes have been reflected in the unaudited pro forma
combined statements of operations. With respect to other potential cost savings,
AMPAM cannot fully quantify these savings. Any potential cost savings are
expected to be partially offset by costs related to AMPAM's new corporate
management and by the costs associated with being a public company. However,
because these costs cannot be accurately quantified at this time, they have not
been included in the pro forma combined financial information of AMPAM.

     The pro forma adjustments are based on preliminary estimates, available
information and certain assumptions that AMPAM management deems appropriate and
may be revised as additional information becomes available. The pro forma
financial data do not purport to represent what AMPAM's combined financial
position or results of operations would actually have been if such transactions
in fact had occurred on those dates and are not necessarily representative of
AMPAM's combined 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 historical financial statements and notes
thereto included elsewhere in this offering memorandum. See also "Risk Factors"
included elsewhere herein.

          AMERICAN PLUMBING & MECHANICAL, INC. AND FOUNDING COMPANIES

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
1. GENERAL:

     American Plumbing & Mechanical, Inc. (AMPAM) was founded to be the leading
national provider of plumbing and mechanical contracting services to the
residential and commercial/institutional markets. AMPAM conducted no operations
prior to April 1, 1999, when it acquired the founding companies concurrently
with entering into the credit facility and the subordinated loan.

     The historical financial statements reflect the financial position and
results of operations of the founding companies and were derived from the
respective founding companies' financial statements. The periods included in
these financial statements for the individual founding companies are for the
year ended December 31, 1998, except for Miller, Sherwood and Croson Ohio for
which the period is the twelve months ended September 30, 1998.

2. ACQUISITION OF FOUNDING COMPANIES:

     On April 1, 1998, AMPAM acquired all of the outstanding capital stock and
other equity interests of the founding companies. The acquisitions were
accounted for using the purchase method of accounting, with Christianson being
reflected as the accounting acquiror. As the accounting acquiror, for accounting
purposes under SEC SAB No. 97, Christianson is treated as (a) having acquired
all the other founding companies (even though AMPAM legally made such
acquisitions), (b) having merged with AMPAM (with purchase accounting reflected
for AMPAM's non-management stock ownership) and (c) representing the financial
history of AMPAM prior to April 1, 1999.

     The consideration paid to the stockholders of the founding companies,
excluding the accounting acquiror (Christianson) was $46.3 million in cash, $4.3
million in seller notes and 7,972,000 shares of common stock. This initial
consideration excludes certain additional shares of common stock and cash that
may be issued to the stockholders of the founding companies if certain targeted
earnings thresholds are satisfied during the year ended December 31, 1999, which
could increase goodwill and amortization of goodwill from the amounts reflected
herein. See "Certain Transactions -- Acquisition of Founding
Companies -- Additional Consideration" included elsewhere herein for further
discussion. The table below does not reflect net transfers of $30.6 million
which represent the distribution of owner amounts such as excess working
capital, distribution of various founding companies' retained earnings,
distribution of various founding companies' S corporation accumulated adjustment
accounts and the distribution of nonoperating assets, net of nonoperating
liabilities, a portion of which were transferred to the owners in connection
with the acquisitions of the founding companies as of March 31, 1999. The excess
working capital distributions are subject to adjustment based upon finalization
of the founding companies working capital balances as of March 31, 1999.

3. UNAUDITED PRO FORMA COMBINED BALANCE SHEET ADJUSTMENTS:

     The following tables summarize unaudited pro forma combined balance sheet
adjustments related to the acquisitions and related transactions, and the
issuance of the notes (in thousands):

      of owner amounts, representing previously undistributed S corporation
      accumulated adjustment accounts, previously undistributed retained
      earnings of C corporations and excess working capital to the owners of the
      founding companies. A portion of such amount was funded using $12.4
      million of notes payable to the owners which was retired with proceeds of
      the credit facility and the subordinated loan and $10.0 million of
      available operating cash from the founding companies. The remaining $6.3
      million of excess working capital (subject to adjustment as described
      above) will be paid to the owners of the founding companies upon
      finalization of the working capital balances as of March 31, 1999.

(b)   Records the distribution of $1.9 million of nonoperating assets, net of
      nonoperating liabilities, to certain stockholders of the founding
      companies as part of the owner amounts prior to the acquisitions.

(c)   Records a liability for the cash, seller notes and the preferred stock of
      the acquisition consideration paid to Christianson, the accounting
      acquirer, and records the merger of AMPAM and Christianson as part of the
      acquisitions.

(d)   Records the purchase of the founding companies by AMPAM, consisting of
      notes payable incurred to finance the $46.3 million in cash, $4.3 million
      in seller notes, 8.1 million shares of common stock valued at its
      estimated fair market value of $6.91 per share and 2.1 million shares of
      restricted common stock issued to Sterling City Capital, LLC and certain
      individuals or consultants valued at its estimated fair market value of
      $5.53 per share. Also records estimated transaction costs (including
      accounting, legal and other) of $5.5 million, $2.0 million of which were
      related to the acquisitions and $3.5 million of which were related to the
      common stock issuance. The total purchase price was approximately $120.6
      million resulting in purchase price in excess of net assets acquired
      (goodwill) of $107.8 million. Also, records deferred taxes for differences

      non-recurring, non-cash compensation charge which management expects to
      record related to the issuance of stock to certain members of AMPAM's
      management. This charge has not been reflected in the pro forma combined
      statements of operations because these costs are non-recurring, non-cash
      costs of the acquisitions and related financings.

      financing costs of $1.2 million) and $30.0 million under the subordinated
      loan net of financing costs of $0.5 million and a discount of $0.3 million
      related to the estimated fair value of the warrants issued in connection
      with the subordinated loan.

      subordinated loan and the credit facility.

(h)   Reflects the repayment of the advances from Sterling City Capital, LLC and
      other payables for transaction expenses and reflects the collection of the
      receivable from the stockholders of AMPAM.

(i)   Records the net cash proceeds of this notes offering, the deferral of $4.8
      million of related debt issuance costs and the use of such proceeds to
      repay the subordinated loan and credit facility advances. Also reflects
      the write off of $0.5 million of deferred loan costs and $0.3 million of
      discount related to the subordinated loan and the write off of $0.3
      million recorded value of the warrants issued in connection with the
      subordinated loan and which will be cancelled in connection with the
      repayment of the subordinated loan.

  Pro Forma Adjustments:


(a)   Reflects the reduction in salaries, bonuses, benefits and lease payments
      to the owners of the founding companies. These reductions in salaries,
      bonuses, benefits and lease payments have been agreed to prospectively in
      accordance with the terms of employment and lease agreements executed as
      part of the acquisitions. The employment agreements are primarily for five
      years, contain restrictions related to competition and provide severance
      for termination of employment in certain circumstances. Also, for the
      three months ended March 31, 1999, reflects the reduction of other income
      to eliminate the gain on disposal of assets related to AMPAM's acquisition
      of the founding companies.

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

      Upon consummation of the acquisitions, AMPAM also expects to record a
      non-recurring, non-cash compensation charge of $7.7 million related to
      shares of common stock and restricted common stock owned by management.
      Such charge represents the fair value of management's shares less the
      amount paid for such shares. The issuances of the management shares were
      made in connection with the organization of AMPAM, and no further
      issuances of this nature are anticipated.


(b)   Reflects the amortization of goodwill to be recorded as a result of these
      acquisitions over a 40-year estimated life, which is management's estimate
      as the period to be benefitted. Upon consummation of the acquisitions,
      AMPAM will record on its balance sheet $107.8 million of goodwill,
      representing the excess of the purchase price for the founding companies
      over the fair value of the net assets to be acquired. Neither the goodwill
      amortization nor the compensation charge will be deductible for federal
      income tax purposes.



(c)   Reflects the net effect on interest expense related to the $114.6 million
      portion of the original issuance of the notes to be used to repay existing
      debt at an estimated rate of 11 5/8% per annum and related amortization of
      unamortized debt discount and offering costs


(d)   Reflects the incremental provision for federal and state income taxes at a
      39% overall tax rate, before nondeductible goodwill and other permanent
      items, relating to the other statements of operations adjustments and for
      income taxes on the pretax income of founding companies that have
      historically elected S corporation tax status.


(e)   Reflects the dividends which would have been owed to the shareholders of
      the redeemable preferred stock.

     We have audited the accompanying balance sheet of American Plumbing &

months ended March 31, 1999. 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

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.

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

     American Plumbing & Mechanical, Inc., a Delaware corporation (AMPAM or the
"Company"), was organized in June 1998 to be the leading provider of plumbing
and mechanical contracting services in the United States, focusing primarily on
the commercial/institutional and residential markets. On April 1, 1999, AMPAM
acquired ten U.S. businesses (see Note 4, the Acquisitions) and completed the
initial financings (see Note 5). On May 19, 1999, the Company completed
additional financings (see Note 6) and intends to continue to acquire through
merger or purchase similar companies to expand its national or regional
operations.

     AMPAM has not conducted any operations, and all activities to date have
related to the Acquisitions. All expenditures of the Company to March 31, 1999
were funded by its founder and then primary stockholder, Sterling City Capital,
LLC, on behalf of the Company. AMPAM has treated these costs as deferred
transaction costs in the accompanying balance sheet. The ability of AMPAM to
generate future income is dependent upon the ability of the Company to manage
the integration of the acquisitions as well as the effect on the combined
companies of the following factors which are discussed in more detail in "Risk
Factors" -- substantial indebtedness and potential incurrence of additional debt
that would be senior to the notes offer (discussed in Note 6), absence of
combined operating history and dependence on future operating performance,
exposure to cyclicality and downturns in construction, availability of skilled
labor, management of growth, reliance on acquisitions, competition, dependence
on key personnel, amortization of goodwill and acquisition and other related
accounting issues, availability of acquisition financing, use of fixed price
contracting and potential materials and labor cost escalations, the Year 2000
issue, potential adverse effect of future acquisitions, potential inability of
the Company to repurchase the notes from the offering (discussed in Note 6) upon
a change of control, lack of a trading market for the notes, seasonality and
fluctuation of quarterly operating results, concentration of customers,
regulations, liability and insurance.

2. STOCKHOLDERS' EQUITY:

  Common Stock

     In connection with the organization and initial capitalization of AMPAM,
the Company issued 2,092,401 shares of restricted common stock at $.01 par value
(restricted common stock). AMPAM has subsequently issued 1,225,116 additional
shares of restricted common stock and common stock to certain management of
AMPAM and other individuals. The shares of restricted common stock have rights
similar to shares of common stock, except that such shares are entitled to elect
one member of the board of directors and are entitled to one-fourth of one vote
for each share held on all other matters, and are subordinate in liquidation to
all other classes of stock. Each share of restricted common stock will convert
into common stock upon the occurrence of certain events. Consequently, as of
December 31, 1998 and as restated for the 1,683-for-one stock split discussed
below, the Company had issued a total of 1,598,901 shares to Sterling City
Capital, LLC and an aggregate of 1,718,616 shares to the executive management of
the Company and other individuals. The shares issued prior to December 1998 were
recorded at their estimated fair value at that time of $.01 par value. The fair
value at that time of all such shares was based on specific factors related to
the Company and the transaction including restrictions on transferability and
sale, the time value of money during the holding period and the substantive
progress of the transaction at each issuance date. On April 1, 1999, the Company
expects to reflect the shares previously issued to Sterling City Capital, LLC
and certainconsultants as acquisition costs (i.e., goodwill) in connection with
the acquisitions. Additionally, the Company expects to record a nonrecurring,
noncash compensation charge related to the shares issued on April 1, 1999 to
management of $7.7 million which will represent the difference between the
estimated fair value ($6.91 for common stock and $5.53 for restricted common
stock) and their recorded values. The management and Sterling City Capital, LLC

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

shares were issued in contemplation of the acquisitions, and no further stock
issuances of this nature are anticipated.

     AMPAM effected a 1,683-for-one stock split in March 1999 for each share of
restricted common stock and each share of common stock of the Company then
outstanding. In addition, the Company increased the number of authorized shares
of common stock to 100,000,000 and increased the number of authorized shares of
$.01 par value preferred stock to 10,000,000. The effects of the stock split and
the increase in the shares of authorized common stock have been retroactively
reflected on the balance sheet, statement of stockholders' equity and in the
accompanying notes. Additionally, the difference between the initial
capitalization value and the par value of total shares outstanding subsequent to
the stock split has been reflected as a receivable from stockholders.

  Preferred Stock

     An aggregate of 1,048,820 shares of preferred stock was issued to certain
stockholders of Christianson at the closing of the acquisitions. Such
Christianson stockholders received their acquisition consideration solely in the
form of cash and shares of preferred stock. The preferred stock is cumulative,
redeemable and convertible and will be recorded at its estimated fair value of
$13 per share.

     The holders of the preferred stock are entitled to receive dividends at an
annual rate of 10% based on the liquidation value (as defined below). The
dividends will be payable in cash semiannually in arrears. The dividend payment
dates are June 30 and December 31, beginning on June 30, 1999. The holders of
the preferred stock are also entitled to receive additional dividends on an
equal share for share basis with the common stock to the extent that the Company
has paid cumulative dividends on a base amount of $13.00 per share of common
stock, as proportionately adjusted for any stock dividends, combinations, splits
or other similar events with respect to such shares, a common stock base amount.
However, the right of the holders of the preferred stock to receive this
preferential dividend will extinguish 40 days after the 25th day following the
date of the final prospectus related to an initial public offering of the
Company's common stock. After such time, the holders will be entitled to share
equally, on a per share basis, in any dividends of the Company with the holders
of common stock.

     The preferred stock is senior to all other classes of the Company's capital
stock (including the common stock) in right of liquidation, dividends and
distributions.

     The liquidation value of the preferred stock is $13.00 per share, plus
accrued and unpaid dividends, as adjusted proportionately for any stock
dividends, combinations, splits or other similar events with respect to such
shares, a liquidation value. In addition, the preferred stock shares equally, on
a per share basis, with the common stock after each share is paid the common
stock base amount plus a cumulative amount of dividends equal to 10% from the
later to occur of the date of issuance of the preferred stock or the date of
issuance of such share of common stock.

     Except under certain circumstances, the preferred stock is not entitled to
vote as a separate class, but votes together with the holders of shares of all
other classes of capital stock of the Company as one class on all matters
submitted to a vote of the Company's stockholders. Each holder of shares of
preferred stock is entitled to the number of votes equal to the largest number
of full shares of common stock into which all shares of preferred stock held by
such holder could be converted at the record date for the determination of the
stockholders entitled to vote on such matters. In all cases where the holders of
shares of preferred stock are required by law to vote separately as a class,
such holders are entitled to one vote for each such share.

     The preferred stock is redeemable at the Company's option at any time and
from time to time, in whole or in part prior to an initial public offering of
AMPAM common stock or an "IPO" for the greater of (i) the fair market value of
the preferred stock and (ii) $13.00 per share of preferred stock, plus, in
                                      F-18
<PAGE>   144
                      AMERICAN PLUMBING & MECHANICAL, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

each case, accrued and unpaid dividends thereon. After an IPO, the Company has
the right to redeem the preferred stock at any time and from time to time, in
whole or in part, at a price equal to the trading price of the common stock at
the time of redemption but in no event for less than $13.00 per share of
preferred stock, plus accrued and unpaid dividends. After the third anniversary
of the date of issuance, the holders of the preferred stock may require the
Company to redeem the preferred stock. In each such case, the redemption price
per share will be equal to the liquidation value plus accrued and unpaid
dividends through the date of redemption.

     Prior to the filing of a registration statement by the Company with the
Securities and Exchange Commission with respect to an IPO, the holders of
preferred stock may convert the preferred stock into common stock on a
share-for-share basis. Not later than the twenty-fifth day after the date of the
final prospectus relating to such IPO, the Company will give notice to each
holder of preferred stock to the effect that the preferred stock will
automatically convert into shares of common stock on the 40th day thereafter
unless such holder gives the Company written notice on or before such date that
such holder elects such conversion not occur with respect to such holder's
shares of preferred stock. In the event the Company does not receive such notice
on or before such date, the preferred stock shall be converted into common stock
at a conversion ratio equal to the liquidation value (without inclusion of
accrued but unpaid dividends) divided by the price per share to the public in
the IPO, effective as of such date.

     The Company may convert the preferred stock following the consummation of
an IPO on a share-for-share basis, unless such conversion would result in the
holder of preferred stock receiving common stock having a value of less than
$13.00 per share, in which case the conversion would be made at a conversion
ratio equal to the liquidation value (without inclusion of accrued but unpaid
dividends) divided by the price per share to the public in the IPO.

  Other Preferred Stock

     Additionally, the board of directors of the Company may authorize the
issuance from time to time shares of one or more new classes or series of
preferred stock. 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 other than the preferred stock.

  Stock Plan

     In February 1999, the Company's board of directors and stockholders
approved the Company's 1999 Stock Plan, or the "stock plan", which provides for
the granting or awarding of incentive or nonqualified stock options, stock
appreciation rights, restricted or phantom stock, and other incentive awards to
directors, officers, key employees and consultants of the Company. The number of
shares authorized and reserved for issuance under the stock plan is the greater
of 3.7 million shares or 15% of the aggregate number of shares of common stock
outstanding. The terms of the option awards will be established by the
Compensation Committee of the Company's board of directors. The Company granted
nonqualified stock options to purchase a total of approximately 2.1 million
shares of common stock to key employees of the Company at the consummation of
the acquisitions. These options vest at the rate of 20 percent per year,
commencing on the first anniversary of the grant date and will expire at the
earliest of ten years from the

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

date of grant, three months following termination of employment other than due
to death or disability, or one year following termination of employment due to
death or disability.

3. STOCK-BASED COMPENSATION:

     Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation," allows entities to choose between a new fair value
method of accounting for employee stock options or similar equity instruments
and the current method of accounting prescribed by Accounting Principles Board
(APB) Opinion No. 25 under which compensation expense is recorded to the extent
that the fair market value of the related stock is in excess of the options
exercise price at date of grant. Entities electing to remain with the accounting
in APB Opinion No. 25 must make pro forma disclosures of net income and earnings
per share as if the fair value method of accounting prescribed in SFAS No. 123
had been applied. The Company will measure compensation expense attributable to
stock options based on the method prescribed in APB Opinion No. 25 and will
provide the required pro forma disclosure of net income and earnings per share,
as applicable, in the notes to future consolidated annual financial statements.

4. FOUNDING COMPANY ACQUISITIONS:

     On April 1, 1999 AMPAM acquired the following entities contemporaneously
with the related initial financings. The entities acquired were:

         Christianson Enterprises, Inc., Christianson Service Company and
         Professional Services, Inc. (collectively, Christianson)
         R.C.R. Plumbing, Inc.
         Teepe's River City Mechanical, Inc.
         Keith Riggs Plumbing, Inc.
         J. A. Croson Company and Franklin Fire Sprinkler Company
         J. A. Croson Company of Florida
         Power Plumbing, Inc.
         Nelson Mechanical Contractors, Inc.
         Sherwood Mechanical, Inc.
         Miller Mechanical Contractors, Inc.

     The Company's results of operations will include the founding companies
beginning April 1, 1999. Prior to April 1, 1999 the Company's results of
operations will be reflected as those of Christianson, since it has been
identified as the accounting acquiror.

     The acquisition consideration delivered upon the closing of the
acquisitions consisted of (i) $99.9 million in cash (which represents a portion
of the $106.3 million cash consideration, subject to adjustment as discussed
below, to be paid to the stockholders of the founding companies), (ii) $5.8
million of seller notes, (iii) 8,898,618 shares of common stock and (iv)
1,048,820 shares of preferred stock. Additionally, approximately 2.1 million
shares of restricted common stock issued to Sterling City Capital, LLC and
certain consultants will be reflected as goodwill as part of the acquisition
transactions.

     Included in the $99.9 million cash acquisition consideration paid upon
closing was a portion of the cash payments to be made to the stockholders of the
founding companies based upon the level of working capital of such founding
company as of the closing date. In the event that the adjusted level of working
capital as of the closing date is more or less than the unadjusted level, the
cash portion of the acquisition consideration payable to such stockholder will
be adjusted accordingly. The stockholders of each founding company were also
entitled to distributions of certain nonoperating assets of such founding
company
                                      F-20
<PAGE>   146

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

(subject to assumption of related liabilities), retained earnings of such
founding company (if a C corporation) or the positive amount of the accumulated
adjustment account (if an S corporation). In addition to the acquisition
consideration and other payments and distributions described above, the
stockholders of each founding company (including certain former shareholders of
Christianson) may receive additional consideration in the event such founding
company generates actual adjusted net income for the year ending December 31,
1999, in excess of a designated target level of net income for that period. Any
additional stock issued or cash paid will be recorded as additional
consideration and, accordingly, will be reflected as goodwill in the financial
statements of the Company.

     The acquisitions will result in a substantial amount of goodwill recorded
on the Company's balance sheet. Goodwill from the acquisitions to be amortized
on a straight-line basis over 40 years. The Company's management will
periodically evaluate recorded goodwill balances, net of accumulated
amortization, for impairment based on the undiscounted cash flows associated
with the asset compared to the carrying amount of that asset.

     In addition, the Company has entered into employment agreements with
certain key executives of the founding companies and is currently negotiating
and expects to enter into employment agreements with the executive officers of
AMPAM. These employment agreements will generally prohibit such individuals from
disclosing confidential information and trade secrets, and restrict such
individuals from competing with the Company for a period of two years following
termination of employment. The initial term of these employment agreements is
five years with provisions for annual extensions at the end of the initial term.

5. INITIAL FINANCINGS

     On April 1, 1999, the Company obtained debt financing in the form of a
credit facility, a subordinated loan, seller notes and a note to Sterling City
Capital, LLC or a sponsor note, which all comprise the initial financings. The
key terms of these debt instruments are as follows:

  The Credit Facility

     The credit facility is a senior secured revolving credit facility in an
aggregate principal amount of $95 million. Amounts borrowed under the credit
facility were used to fund a part of the cash portion of the acquisition
consideration and will be used to fund future acquisitions and to provide
financing of general corporate purposes. The credit facility bears interest, at
the option of the Company, at the base rate of the arranging bank plus an
applicable margin or at LIBOR plus an applicable margin. The applicable margin
fluctuates based on the Company's ratio of funded debt to EBITDA and will be
between 1.50% and 2.50% above LIBOR or 0.00% and 1.00% above the arranging banks
base rate. Interest is payable no less frequently than quarterly in arrears. The
term of the credit facility is three years from the date of closing of the
acquisitions and all principal amounts borrowed will be payable in full at
maturity.

     The credit facility is secured by (1) the accounts receivable, the seller
notes, inventory, equipment and other personal property of the Company and (2)
all of the capital stock owned by AMPAM of its existing or later-formed domestic
subsidiaries. The Company is required to make prepayments or commitment
reductions on the credit facility under certain circumstances.

     The credit facility requires the Company to maintain compliance with
certain specified financial covenants including maximum ratios of funded debt to
EBITDA, a minimum fixed charge coverage ratio, a minimum net worth and other
restrictive covenants. Additionally, the terms of the credit facility limit the
ability of the Company to incur additional indebtedness, dispose of assets, make
acquisitions or other investments and to make various other payments.

                      AMERICAN PLUMBING & MECHANICAL, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     As of April 1, 1999, $70.3 million was outstanding on the credit facility.
The Company repaid such outstanding amount in full with the proceeds from the
offering discussed in Note 6.

  The Subordinated Loan

     The subordinated loan was a senior subordinated loan in an aggregate
principal amount of $30.0 million. The subordinated loan was a senior
subordinated obligation of the Company, subordinated to all other of the
Company's senior debt (including the credit facility) and senior to all other
subordinated debt of the Company (including the seller notes). Amounts borrowed
under the subordinated loan were used to fund a portion of the cash acquisition
consideration. The subordinated loan bore interest at an annual rate equal to
three months LIBOR plus 350 basis points. Interest was payable quarterly in
arrears.

     Concurrently with entering into the subordinated loan, AMPAM deposited into
escrow, for the benefit of the lenders, warrants to purchase common stock. The
warrants terminated when the subordinated loan was repaid, upon closing of the
offering discussed in Note 6. The Company recorded the warrants as an increase
to stockholder's equity for their estimated fair value (approximately $0.3
million) and a corresponding discount to the subordinated loan recorded value.
The discount was amortized as additional interest expense.

     As of April 1, 1999, $30.0 million was outstanding on the subordinated
loan. The Company repaid such outstanding amount in full with the proceeds from
the offering discussed below. Upon repayment, the Company wrote off deferred
loan issuance costs of $0.5 million and the discount of approximately $0.3
million.

  The Seller Notes

     The Company issued $5.8 million principal amount of seller notes due on
April 1, 2002. The seller notes bore interest at the rate of 10% per annum.

     Interest on the seller notes was payable quarterly, commencing 90 days from
the date of issuance. The seller notes were unsecured obligations of the
Company, subordinated in the right of payment to any and all existing and future
senior indebtedness of the Company (including the credit facility and the
subordinated loan). The seller notes were repaid upon completion of the offering
discussed in Note 6.

  The Sponsor Note

     The Company issued a subordinated note payable to Sterling City Capital,
LLC on April 1, 1999 in settlement of the amounts due to stockholders of $3.5
million ($2.5 million at December 31, 1998). The sponsor note was due on April
1, 2002 and bore interest payable quarterly at the annual rate of 10%. The
sponsor note was redeemed by the Company upon completion of the offering
discussed in Note 6.

6. THE OFFERING AND THE EXCHANGE OFFERING

     On May 19, 1999, the Company completed an offering of $125.0 million of
senior subordinated notes due in 2008. The notes are subordinated to all
existing and future senior indebtedness of the Company and are guaranteed by
each of the Company's current and future subsidiaries. The Company has the
option to redeem the notes at any time on or after 2004, at specified redemption
prices. Before 2002, the Company also has the option, under certain
circumstances, to redeem up to 35% of the aggregate principal amount of the
notes at specified redemption prices. Additionally, the Company is required
under certain circumstances to repurchase the notes at specified redemption
prices in the event of a change in control.

     Additionally, the terms of the notes limit the ability of the Company to,
among other things, incur additional indebtedness, dispose of assets, make
acquisitions, make other investments, pay dividends and to

                                      F-22

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

make various other payments. In conjunction with this offering, the Company
entered into a registration rights agreement whereby the Company agreed to file
a registration statement within 60 days after the close of the offering that
would enable noteholders to exchange their privately placed notes for publicly
registered notes with substantially identical terms. Additionally, the Company
agreed, among other things, to use their reasonable best efforts to cause the
registration statement to become effective within 150 days after the close of
the offering and to be completed within 180 days after the close of the
offering. If the Company does not comply with their obligations (including their
reasonable best efforts) under the registration rights agreement, the interest
rate on the notes will increase.

     The net proceeds from the offering of approximately $117.7 million, were
used (1) to repay the outstanding indebtedness ($70.3 million as of April 1,
1999) under the $95.0 million credit facility discussed above (2) to repay the
$30.0 million subordinated loan (3) to repay the seller notes and the sponsor
note ($9.3 million as of April 1, 1999) and (4) for general corporate purposes.

     The Company is currently in the process of registering the privately placed
notes with the Securities and Exchange Commission and, accordingly, intends to
meet their obligations, as described above, under the registration rights
agreement. No assurance can be made that the exchange offering will be
completed.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Christianson Enterprises, Inc.,
and Combined Companies:

     We have audited the accompanying combined balance sheets of Christianson
Enterprises, Inc., and Combined Companies (the Company) as of December 31, 1997
and 1998 and March 31, 1999, and the related combined statements of operations,
cash flows and stockholders' equity for the year ended August 31, 1996, the four
months ended December 31, 1996, the years ended December 31, 1997 and 1998 and
the three months ended March 31, 1999. 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 combined financial position of the Company as of
December 31, 1997 and 1998 and March 31, 1999, and the results of their
operations and their cash flows for each of the year ended August 31, 1996, the
four months ended December 31, 1996, the years ended December 31, 1997 and 1998,
and the three months ended March 31, 1999 in conformity with generally accepted
accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

     Christianson Enterprises, Inc., a Texas Corporation, and its wholly owned
subsidiaries, together with Christianson Service Company and GGR Leasing
Corporation, both Texas Corporations (the Combined Companies), which are owned
by the stockholders of Christianson Enterprises, Inc., are collectively referred
to herein as the "Company." The Company provides plumbing and air conditioning
installation and repair services primarily for single-family residential markets
in Texas. The Company performs the majority of its services under fixed-price
contracts which generally span three months.

     The Company and its stockholders entered into a definitive agreement with
American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which all outstanding
shares of the Company's common stock were exchanged for cash, notes and shares
of AMPAM common and preferred stock concurrently with the consummation of the
related financing.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Principles of Consolidation and Combination

     The accompanying financial statements present Christianson Enterprises,
Inc., consolidated with its wholly owned subsidiaries, together with
Christianson Service Company and GGR Leasing Corporation on a combined basis.
All significant intercompany transactions have been eliminated in consolidation
and combination.

     Effective December 31, 1997, Christianson Enterprises, Inc., and its
subsidiaries changed their year ends from August 31 to December 31. Christianson
Service Company and GGR Leasing Corporation have each reported on a December 31
year-end since inception. For the years ended August 31, 1995 and 1996, the
results of operations for Christianson Service Company and GGR Leasing
Corporation have been conformed to an August 31 year-end. Generally accepted
accounting principles have been consistently applied to the financial statements
for all periods presented.

  Interim Financial Information

     The interim financial statements for the four months ended December 31,
1995, and the three months ended March 31, 1998, are unaudited and have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of the Company's management, the unaudited
interim financial statements contain all adjustments (consisting of normal
recurring adjustments) considered necessary for a fair presentation. The results
of operations for the interim periods are not necessarily indicative of the
results for the entire fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  Inventories

     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

                             AND COMBINED COMPANIES

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statement of operations.

  Revenue Recognition

     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of cost incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor and depreciation
costs. Provisions for the total estimated losses on uncompleted contracts are
made in the period in which such losses are determined. Changes in job
performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.

     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.

  Warranty Costs

     For certain contracts, the Company warrants labor for one year after
completion of a plumbing or air conditioning installation. The Company generally
warrants labor for 90 days after plumbing and air conditioner repairs. A reserve
for warranty costs is recorded based upon the historical level of warranty
claims and management's estimate of future costs.

  Provision for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances.

  Officers' Compensation

     Total officers' compensation for the years ended August 31, 1996, and
December 31, 1997 and 1998, the four months ended December 31, 1995 and 1996,
and the three months ended March 31, 1999, was $6,905,000, $6,643,000,
$10,701,000, $2,257,000 (unaudited), $3,763,000, and $400,000, respectively.
Such amounts are included within selling, general and administrative expenses in
the accompanying statements of operations.

  Income Taxes

     Effective January 1, 1997, Christianson Enterprises, Inc., including its
wholly owned subsidiaries, elected S Corporation status. Christianson Service
Company and GGR Leasing Corporation have elected

                             AND COMBINED COMPANIES

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

S Corporation status. Under S Corporation status, as defined by the Internal
Revenue Code, the Company itself is not subject to taxation for federal
purposes; rather, the stockholders report their share of the Company's taxable
earnings or losses in their personal tax returns. Certain states do not
recognize S Corporation status for purposes of state taxation. Consequently, the
provision for current and deferred income taxes for the years ended December 31,
1997, 1998 and the three months ended March 31, 1999, consists of only state
income taxes. The Company terminated its S Corporation status concurrently with
the effective date of the merger discussed in Note 13.

     The Company follows the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards (SFAS) No. 109,
"Accounting for Income Taxes." Under this method, deferred assets and
liabilities are recorded for future tax consequences of temporary 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
underlying assets or liabilities are recovered or settled.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
Accordingly, in the event that facts and circumstances indicate that property
and equipment or other assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if an impairment of such property is necessary. The
effect of any impairment would be to expense the difference between the fair
value of such property and its carrying value. Adoption of this standard did not
have a material effect on the financial position or results of operations of the
Company.

  Reclassifications

     Certain reclassifications have been made to the prior-year financial
statements to conform to the current-year presentation.

     Effective January 1, 1997, Christianson Enterprises, Inc., elected S
Corporation status. As such, Christianson Enterprises, Inc., was no longer
directly responsible for any federal deferred tax liability. The removal of the
federal deferred tax liability of $16,000 at December 31, 1996, is recognized in
the 1997 statement of operations for the year ended December 31, 1997.

8. STOCKHOLDERS' EQUITY:

     Effective May 13, 1998, the outstanding shares of common stock of

reflected retroactively for all periods presented in the accompanying financial
statements.

     Shares of common stock of Christianson Enterprises, Inc., are not
transferable unless they are first offered for sale to Christianson Enterprises,
Inc. and secondly to the other shareholders of Christianson Enterprises, Inc.

9. RELATED-PARTY TRANSACTIONS:

  Leases

     As discussed in Note 6, the Company leases its facilities and its furniture
and fixtures in Austin and San Antonio, Texas, from related parties. It is
management's opinion that such leases are at market value.

  Other

     Through December 31, 1995, the Company subcontracted its construction labor
to a related party. The Company was charged for such labor based on the related
party's actual costs. For the year ended August 31, 1996, and the four months
ended December 31, 1995, subcontractor labor costs reflected within cost of
revenues in the accompanying statements of operations were $2,663,000 and
$2,663,000 (unaudited), respectively. This relationship was terminated effective
December 31, 1995.

     Also through December 31, 1995, the related party provided workers'
compensation insurance to its employees through a self-insurance program. The
related party charged the Company an agreed-upon rate for such insurance based
on an estimate of the cost of workers' compensation insurance as a subscriber
under the Texas risk pool. Claims were administered and paid by the related
party. For the year ended August 31, 1996, and the four months ended December
31, 1995, workers' compensation insurance costs reflected within cost of
services in the accompanying statements of operations were $268,000 and $268,000
(unaudited), respectively. This relationship was terminated effective December
31, 1995.

     In connection with various administrative and management services provided
to the related party, the Company charged a fee to the related party for such
services. For the years ended August 31, 1996, and the four months ended
December 31, 1995, the Company charged the related party $225,000 and $225,000
(unaudited), respectively. These amounts are included within other income in the
accompanying statements of operations. As discussed above, the relationship was
terminated December 31, 1995; therefore, no fees were charged subsequent to this
date.

10. FINANCIAL INSTRUMENTS:

     The Company's financial instruments consist of cash and cash equivalents,
capital lease obligations and debt. The Company believes that the carrying value
of these instruments on the accompanying balance sheets approximates their fair
values.

11. COMMITMENTS AND CONTINGENCIES:

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability, workers' compensation and an umbrella policy.
The Company has not incurred significant claims or losses on any of these
insurance policies.

     Beginning on May 1, 1998, the Company self-insured for medical claims up to
$50,000 per year per individual covered, with a $642,000 aggregate maximum
exposure per year. Claims in excess of these amounts are covered by a stop-loss
policy. At December 31, 1998, and March 31, 1999, the Company has

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

recorded reserves within accounts payable and accrued liabilities for its
portion of self-insurance claims based on estimated claims.

12. MAJOR CUSTOMERS AND RISK CONCENTRATION:

     The Company had sales of approximately 24.1 percent, 22.8 percent, 23.1
percent, 23.5 percent (unaudited), 23.4 percent and 18.4 percent of total sales
to one major customer during the years ended August 31, 1996, December 31, 1997
and 1998, the four months ended December 31, 1995 and 1996 and the three months
ended March 31, 1999, respectively.

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is, by law, granted a lien interest on the
work until paid. The Company is exposed to potential credit risk related to
changes in business and economic factors within the region. However, management
believes that its contract acceptance, billing and collection policies are
adequate to minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas in which it operates.

13. SUBSEQUENT EVENT:

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash, notes and common and preferred stock of AMPAM,
after which the Company is a wholly owned subsidiary of AMPAM. In connection
with the merger, the Company made cash distributions which represent the
Company's estimated S Corporation accumulated adjustment account.

     As discussed in Note 2, in connection with the merger, the Company
converted from an S Corporation to a C Corporation. Upon conversion to C
Corporation status, the Company recorded deferred taxes for which it will be
responsible. If the S Corporation status had been terminated as of December 31,
1998 or March 31, 1999, the Company would have recorded an additional deferred
tax asset of approximately $471,000 and $296,000, respectively, due primarily to
reserves and accrued expenses and an additional deferred tax liability of
approximately $379,000 and $121,000, respectively, due primarily to differences
between book and tax depreciation and revenue recognition.

     Concurrently with the merger, the Company entered into agreements with the
stockholders to lease land and buildings used in the Company's operations for a
negotiated amount and term.

                         NOTES TO FINANCIAL STATEMENTS
(1) BUSINESS AND ORGANIZATION:

     RCR Plumbing, Inc., a California corporation (the Company), focuses on
providing installation of plumbing and heating, ventilation, and air
conditioning (HVAC) primarily for developers and builders of single-family and
multi-family developments, apartment buildings and condominiums. The Company
performs the majority of its contract work under fixed price arrangements with
contract terms generally ranging from six to 12 months. The Company performs the
majority of its work in California and Nevada.

     The Company and its stockholders entered into a definitive agreement with
American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which all outstanding
shares of the Company's common stock were exchanged for cash, notes and shares
of AMPAM common stock concurrently with the consummation of the related
financing.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Interim Financial Information

     The interim financial statements as of March 31, 1999, and for the three
months ended March 31, 1998 and 1999, are unaudited and have been prepared
pursuant to the rules and regulations of the Securities and Exchange Commission.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of the Company's management, the unaudited interim financial
statements contain all adjustments (consisting of normal recurring adjustments)
considered necessary for a fair presentation. The results of operations for the
interim periods are not necessarily indicative of the results for the entire
fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  Accounts Receivable and Provision for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances.

  Inventories

     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Revenue Recognition

     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of cost incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor and depreciation
costs. Provisions for the total estimated losses on uncompleted contracts are
made in the period in which such losses are determined. Changes in job
performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.

     A portion of the Company's receivables are comprised of retainages. These
balances billed but not paid by customers pursuant to retainage provisions in
construction contracts will be due upon completion of the contracts and
acceptance by the customer. Based on the Company's experience with similar
contracts in recent years, the retention balance at each balance sheet date will
be collected within the subsequent fiscal year.

     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.

  Warranty Costs

     The Company generally warrants labor and materials for twelve months after
installation of a new plumbing or HVAC contract. A reserve for warranty costs is
recorded based upon the historical level of warranty claims and management's
estimate of future costs.

  Income Taxes

     The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company is not subject to taxation for federal
purposes. Under S Corporation status, the stockholders report their shares of
the Company's taxable earnings or losses in their personal tax returns. Certain
states do not recognize the S Corporation status for purposes of state taxation.
The provision for income taxes in the accompanying statements of operations
represents the state tax provision related to such states. The Company
terminated its S Corporation status concurrently with the effective date of the
merger discussed in Note 13.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.
Accordingly, in the event that facts and circumstances indicate that property
and equipment or other assets may be impaired, an evaluation of
                                      F-44

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

recoverability would be performed. If an evaluation is required, the estimated
future undiscounted cash flows associated with the asset are compared to the
asset's carrying amount to determine if an impairment of such property is
necessary. The effect of any impairment would be to expense the difference
between the fair value of such property and its carrying value. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

(10) COMMITMENTS AND CONTINGENCIES:

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant claims or losses on any of these insurance policies.

(11) CONCENTRATION OF CREDIT RISK:

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is, by law, granted a lien interest in the
work until paid. The Company is exposed to potential credit risk related to
changes in business and economic factors within the region. However, management
believes that its contract acceptance, billing and collection policies are
adequate to minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas which it operates.

(12) SALE OF COMMON STOCK:

     During 1998, one of the Company's stockholders sold all his shares to
another stockholder. Subsequent to this transaction, the Company was owned by
the two remaining stockholders.

(13) EVENT SUBSEQUENT TO DATE OF REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
     (UNAUDITED):

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash, notes and stock of AMPAM, after which the Company
is a wholly owned subsidiary of AMPAM.

     In connection with the completion of the AMPAM Agreement, the Company
transferred certain assets of the Company to the stockholders with a fair market
value of approximately $2,144,000. In return the stockholders assumed
liabilities related to those assets of approximately $1,332,000. In accordance
with Accounting Principles Board No. 29, the Company recognized a gain on the
transfer of the property of approximately $605,000. The difference between the
fair market value of the assets transferred and the liabilities assumed was
approximately $812,000 and was accounted for as a distribution to stockholders
equity. Additionally, the Company made cash distributions which represent the
Company's estimated S corporation accumulated adjustment account.

     As discussed in Note 2, in connection with the merger, the Company
converted from an S Corporation to a C Corporation. Upon conversion to C
Corporation status, the Company recorded deferred taxes for which it will be
responsible. If the S Corporation had been terminated as of December 31, 1998 or
March 31, 1999, the Company would have recorded a net current deferred tax
liability of approximately $1,850,356 and $719,318, respectively, and a net
non-current deferred tax liability of approximately $156,908 and $168,038,
respectively. Deferred tax assets are a result of bad debt allowances, and
warranty and other liability reserves. Deferred tax liabilities are a result of
differences between book and tax depreciation, and differences between the
percentage of completion and completed contract method of accounting for its
contracts.

     Concurrently with the merger, the Company entered into agreements with the
stockholders to lease office space used in the Company's operations for a
negotiated amount and term.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
Teepe's River City Mechanical, Inc.:

     We have audited the accompanying balance sheets of Teepe's River City
Mechanical, Inc. as of December 31, 1997, 1998 and March 31, 1999, and the
related statements of operations, cash flows and stockholders' equity for each
of the three years in the period ended December 31, 1998 and for the three
months ended March 31, 1999. 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 Teepe's River City
Mechanical, Inc. as of December 31, 1997, 1998 and March 31, 1999, and the
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1998, and for the three months ended March 31, 1999,
in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

     Teepe's River City Mechanical, Inc., an Ohio corporation (the Company),
provides plumbing and mechanical services for commercial and industrial
properties. The Company performs the majority of its contract work under fixed
price contracts with contract terms generally ranging from six to twelve months.
The Company performs the majority of its work in Ohio, Kentucky and Indiana.

     The Company and its stockholders intend to enter into a definitive
agreement with American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which
all outstanding shares of the Company's common stock will be exchanged for cash,
notes and shares of AMPAM common stock concurrently with the consummation of the
related financing.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Interim Financial Information

     The interim financial statements for the three months ended March 31, 1998,
are unaudited and have been pursuant to the rules and regulations of the
Securities and Exchange Commission. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of the Company's management,
the unaudited interim financial statements contain all adjustments (consisting
of normal recurring adjustments) considered necessary for a fair presentation.
The results of operations for the interim periods are not necessarily indicative
of the results for the entire fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  Accounts Receivable and Allowance for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances.

  Inventories

     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Revenue Recognition

     Revenues from construction contracts are recognized on the
percentage-of-completion method measured by the percentage of cost incurred to
date to total estimated costs for each contract. Contract costs include all
direct material and labor costs and those indirect costs related to contract
performance, such as indirect labor and depreciation costs. Provisions for the
total estimated losses on uncompleted contracts are made in the period in which
such losses are determined. Changes in job performance, job conditions,
estimated profitability and final contract settlements may result in revisions
to costs and income and their effects are recognized in the period in which the
revisions are determined. An amount equal to contract costs attributable to
claims is included in revenues when realization is probable and the amount can
be reliably estimated. Revenue from noncontract work is recognized when the
services are performed.

     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer.

     The current asset, "costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.

  Warranty Costs

     For certain contracts, the Company warrants labor for one year after
installation of plumbing or mechanical systems. A reserve for warranty costs is
recorded based upon the historical level of warranty claims and management's
estimate of future costs.

  Income Taxes

     The Company, which is a C Corporation, follows the liability method of
accounting for income taxes in accordance with Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting for Income Taxes." Under this method,
deferred assets and liabilities are recorded for future tax consequences of
temporary differences between the financial reporting and tax basis of assets
and liabilities, and are measured using the enacted tax rates and laws that will
be in effect when the underlying assets or liabilities are recovered or settled.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
Accordingly, in the event that facts and circumstances indicate that property
and equipment or other assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if an impairment of such property is necessary. The
effect of any impairment would be to expense the difference between the fair
value of such property and its carrying value. Adoption of this standard did not
have a material effect on the financial position or results of operations of the
Company.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

9. RELATED-PARTY TRANSACTIONS:

     In July 1998, the Company sold certain property to an entity controlled by
the Company's majority stockholder. Concurrent with the sale, the Company
entered into a lease with the entity for the same property. The lease calls for
monthly lease payments of approximately $12,000. The sale leaseback was recorded
under the deposit method using Statement of Financial Accounting Standards
(SFAS) No. 98, "Accounting for Leases" and, as such, the liability of $736,000
and $724,000 is recorded at December 31, 1998, and March 31, 1999, respectively,
as a deposit and all payments will be charged against the deposit liability,
that is included in other long-term obligations on the balance sheet.

     In 1997, the Company entered into an operating lease for its Columbus, Ohio
building with a related entity. The building lease expires in August 2003 with
an option to renew for two five year terms. The lease calls for monthly lease
payments of approximately $5,000. Total rent paid under this was $18,000,
$55,000 and $15,000 in 1997, 1998 and for the three months ended March 31, 1999,
respectively.

     As of December 31, 1997 and 1998, and March 31, 1999, the Company has loans
to a shareholder and to an officer. Both receivables are classified as related
party receivables for balance sheet presentation. The loan to the shareholder
has an outstanding balance of $114,000, $122,940 and $121,752 at December 31,
1997, 1998, and March 31, 1999, respectively. The loan bears interest at the
applicable federal rate (5.9% at December 31, 1997, 1998 and 5.9% at March 31,
1999). Total interest income related to this loan was $7,000 for December 31,
1997 and 1998, and $1,771 for the three months ended March 31, 1999. The loan to
the officer of the Company had an outstanding balance of $100,000, $98,000 and
$98,000 at December 31, 1997, 1998, and March 31, 1999, respectively. The loan
bears interest at the prime rate, 8.5% at December 31, 1997 and 1998, and 7.75%
at March 31, 1999, respectively, and matures in August 1999.

10. EMPLOYEE BENEFIT PLAN:

     The Company has a defined contribution profit-sharing plan for all
employees with immediate vesting. The plan provides for the Company to match the
first $500 contributed by each employee, which vests over a period of seven
years. Total contributions by the Company under the plan were approximately
$50,000, $57,000, $71,000 and $54,000 for the years ended December 31, 1996,
1997, 1998 and the three months ended March 31, 1999, respectively.

     The Company's field personnel elected to have the Company contribute a
portion of their wages earned on prevailing wage contracts to a multiemployer
plan. The expense related to this plan was $333,000, $570,000, $501,700 and
$103,941 for the years ended December 31, 1996, 1997, 1998 and the three months
ended March 31, 1999, respectively.

11. FINANCIAL INSTRUMENTS:

     The Company's financial instruments consist of cash and cash equivalents, a
notes payable and long-term debt. The Company believes that the carrying value
of these instruments on the accompanying balance sheets approximates their fair
value.

12. COMMITMENTS AND CONTINGENCIES:

  Guarantees

     The Company is the guarantor on several loans entered into by a company
affiliated through common ownership. The loans had outstanding balances
$1,937,000, $3,037,000 and $3,020,000 at December 31, 1997, 1998, and March
31,1999, respectively.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant claims or losses on any of these insurance policies. The
Company participates in a state-wide workers' compensation program. In June
1998, the Company received a one-time refund of $422,000 as a result of positive
claims experience and strong earnings of the workers' compensation fund. The
refund is reflected as a reduction in cost of services in 1998.

13. MAJOR CUSTOMERS AND RISK CONCENTRATION:

     The Company had sales greater than 10% of the total revenues for one,
three, two and one major customers during the years ended December 31, 1996,
1997, 1998, and for the three months ended March 31, 1999, respectively. These
customers represented approximately 10.4%, 30.5%, 23.4% and 10.0% of total
revenues during the years ended December 31, 1996, 1997, 1998, and for the three
months ended March 31, 1999, respectively.

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is, by law, granted a lien interest in the
work until paid. The Company is exposed to potential credit risk related to
changes in business and economic factors within Ohio, Kentucky and Indiana.
However, management believes that its contract acceptance, billing and
collection policies are adequate to minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas which it operates.

14. SUBSEQUENT EVENT:

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash, notes and stock of AMPAM, after which the Company
is a wholly owned subsidiary of AMPAM.

     Concurrently with the merger, the Company entered into agreements with the
stockholder to lease land and buildings used in the Company's operations for a
negotiated amount and term.

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

     Keith Riggs Plumbing, Inc., an Arizona corporation (the Company), provides
plumbing services primarily for residential contractors. The Company performs
the majority of its contract work under fixed price contracts in the state of
Arizona.

     The Company and its stockholders intend to enter into a definitive
agreement with American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which
all outstanding shares of the Company's common stock will be exchanged for cash
and shares of AMPAM common stock concurrently with the consummation of the
related financing.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Interim Financial Information

     The interim financial statements as of March 31, 1999, and for the three
months ended March 31, 1998 and 1999, are unaudited and have been prepared
pursuant to the rules and regulations of the Securities and Exchange Commission.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of the Company's management, the unaudited interim financial
statements contain all adjustments (consisting of normal recurring adjustments)
considered necessary for a fair presentation. The results of operations for the
interim periods are not necessarily indicative of the results for the entire
fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments with an original
maturity of three months or less when purchased to be cash equivalents.

  Receivable and Provision for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances.

  Inventories

     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.

  Revenue Recognition

     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenue from construction
contracts is generally recognized on the

                                      F-68

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

percentage-of-completion method measured by the percentage of cost incurred to
date to total estimated costs for each contract. Contract costs include all
direct material and labor costs and those indirect costs related to contract
performance, such as indirect labor and depreciation costs.

  Warranty Costs

     The Company warrants labor for two years after installation of new
plumbing. The Company generally warrants labor for 30 days after repair of
existing plumbing. A reserve for warranty costs is recorded based upon the
historical level of warranty claims and management's estimate of future costs.

  Income Taxes

     The Company has elected Subchapter S status under the Internal Revenue
Code. Therefore, the tax effects of the Company's operations will be reflected
on the tax returns of the individual stockholders. The Company will terminate
its S Corporation status concurrently with the effective date of the merger
discussed in Note 13.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.
Accordingly, in the event that facts and circumstances indicate that property
and equipment or other assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if an impairment of such property is necessary. The
effect of any impairment would be to expense the difference between the fair
value of such property and its carrying value.

5. LOAN AGREEMENT:

     At December 31, 1998, and March 31, 1999, the Company had a Loan Agreement
(the Agreement) with a bank that provides for a revolving line of credit of
$550,000 and a term loan of $450,000. The proceeds of the revolving line of
credit are used to finance temporary increases in inventory and accounts
receivable and provide funds to take advantage of trade discounts. Proceeds of
the term loan are used to provide working capital.

     The revolving line of credit requires payment of interest monthly at .5%
over the prime rate, which was 8.25% at December 31, 1998, and 7.75% at March
31, 1999, and matures on May 28, 1999. Borrowings on the line of credit at
December 31, 1997, totaled $450,000. There were no borrowings at December 31,
1998, and March 31, 1999. The line of credit was terminated subsequent to March
31, 1999.

     The term loan is payable in monthly installments of $7,500 plus interest at
9% and matures in June 2002. At December 31, 1997 and 1998, and March 31, 1999,
$395,625, $298,125 and $283,125 (unaudited). respectively, was outstanding on
the term loan. Subsequent to March 31, 1999, and in connection with the merger
(see Note 13), the Company paid in full the amounts outstanding under the term
loan.

     The Agreement is collateralized by receivables, inventory and equipment. In
addition, the shareholders of the Company are guarantors of the term loan.

     Under the terms of the Agreement, the Company is required to maintain
certain financial covenants on a monthly basis, the most restrictive of which
are the following: maintenance of a debt to tangible net worth ratio of not more
than 3.5 to 1.0; a debt service coverage ratio greater than 1.5 to 1.0; and a
current ratio of not less than 1.1 to 1.0. The Agreement also places
restrictions on the Company's ability to create

7. STOCKHOLDERS' EQUITY:

  Common Stock Split

     On February 1, 1998, the Company declared a 1.025 for 1.0 stock split of
the Company's common stock to stockholders of record on December 31, 1997. All
share amounts have been restated to reflect the split.

  Buy-Sell Agreement

     The Keith Riggs Plumbing, Inc. Stockholders' Buy-Sell Agreement (the
"Buy-Sell Agreement") restricts the sale, assignment, transfer, pledge or other
disposition of the Company's shares without the prior written consent of the
other stockholders. Additionally, under certain circumstances shares of stock
shall be repurchased by the Company. The redemption price is to be based on an
annual certificate of value or, in the absence of the former, on an appraisal
performed at the time of the transaction, and is to be paid according to the
terms stipulated in the Buy-Sell Agreement.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     The Buy-Sell Agreement also provides for the issuance of 100 shares of the
Company's common stock to any lineal descendant of the founders based upon
attaining 10 years of continuous service and shall receive 100 shares for each
additional year of service thereafter until the 20th year of service, when an
additional 1,000 shares shall be issued for a maximum of 2,000 shares. The years
of service are measured at December 31st and the shares are issued on February
1st of the subsequent year. Such shares may be issued through the issuance of
new shares or existing shares. On February 1, 1998 and 1999, 100 shares of the
Company's common stock were issued in connection with the terms of this
Agreement. The Company's stockholders elected to issue the shares from their
existing holdings.

  Treasury Stock

     Treasury stock consists of 2,050 shares redeemed from one stockholder in
1994 for an 11-year note payable collateralized by a life insurance policy. The
Company recorded the value of the treasury shares at the present value of the
note discounted at 8%. In 1997, upon the death of the stockholder and receipt of
the insurance proceeds, the Company repaid this debt in its entirety. The
$55,062 loss associated with this early extinguishment of debt with a related
party was recorded as an additional cost of treasury stock.

8. RELATED-PARTY TRANSACTIONS:

     At December 31, 1998, the Company had a note payable due to one stockholder
amounting to $10,600. This note is noninterest bearing and is due on demand. At
December 31, 1998, and March 31, 1999, the Company had a note payable to RGS
Land LLC (RGS), a company wholly owned by the Company's stockholders, amounting
to $90,008 and $74,008 (unaudited), respectively. This note is payable in
monthly installments of $1,333 plus interest at prime plus 2% and matures in
July 2004. The proceeds received from the RGS note were used to construct the
Glendale, Arizona facility. Subsequent to March 31, 1999, these notes were paid
in full.

     The Company leases its main premises in Mesa, Arizona and in Glendale,
Arizona, from the principal stockholders. The Company's lease obligation is on a
month to month basis with no fixed term. Rent expense for these locations
totaled $61,330, $63,878 and $11,118 (unaudited) for the years ended December
31, 1997 and 1998, and the three months ended March 31, 1999, respectively.
Management of the Company believes that the approximate market rental value for
these properties is $180,000 per year.

9. EMPLOYEE BENEFIT PLAN:

     Effective January 1, 1997, the Company established the Keith Riggs
Plumbing, Inc. 401(k) Plan. The Plan covers full time employees and provides for
employer contributions on a discretionary basis. The Company's expense for the
years ended December 31, 1997 and 1998, and the three months ended March 31,
1999, totaled $25,448, $32,383 and $0 (unaudited), respectively.

11. COMMITMENTS AND CONTINGENCIES:

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability, property and workers' compensation. The
Company has not incurred significant claims or losses on any of these insurance
policies. The workers' compensation policy provides for an annual refundable
deposit in addition to the premium payments. As of March 31, 1999, $200,000
(unaudited) has been accrued for a 1996 and 1997 compensation refund.

  Operating Leases

     In addition to the related-party leases described in Note 8, the Company
leases certain equipment from unaffiliated third parties under noncancellable
operating leases. Rent expense related to these lease agreements totaled
$24,371, $31,818 and $20,863 (unaudited) for the years ended December 31, 1997
and 1998, and the three months ended March 31, 1999, respectively. Future
minimum lease payments under these noncancellable leases are as follows:

</TABLE>

     Financial instruments which potentially expose the Company to
concentrations of credit risk, as defined by SFAS No. 105, consist primarily of
contract accounts receivable. At December 31, 1998, and March 31, 1999,
approximately 39% and 47% (unaudited) of contract accounts receivable are due
from three customers.

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is, by law, granted a lien interest in the
work until paid. The Company is exposed to potential credit risk related to
changes in business and economic factors within the state of Arizona.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

However, management believes that its contract acceptance, billing and
collection policies are adequate to minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas which it operates.

     The Company relies on several key vendors to supply its primary material
needs. However, the Company believes that other suppliers could provide for the
Company's needs on comparable terms. Abrupt changes in the supply flow could,
however cause a delay and a possible inability to meet its commitments on
schedule or a possible loss of sales which would offset operating results
adversely.

13. EVENTS SUBSEQUENT TO DATE OF REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
    (UNAUDITED):

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash and stock of AMPAM, after which the Company is a
wholly owned subsidiary of AMPAM.

     In connection with the merger, the Company sold or distributed certain
non-operating assets and attendant liabilities, if any, to the stockholders.
Additionally, the Company made cash distributions prior to the merger which
represent the Company's estimated S corporation accumulated adjustment account.

     As discussed in Note 2, in connection with the merger, the Company
converted from an S corporation to a C corporation. Upon conversion to C
corporation status, the Company recorded deferred taxes for which it will be
responsible. If the S corporation had been terminated as of December 31, 1998,
and March 31, 1999, the Company would have recorded a deferred tax asset of
approximately $140,000 and $192,000, respectively, due to various book reserves
and accruals and a deferred tax liability of approximately $246,000 and
$265,000, respectively, due to differences between book and tax depreciation and
due to an accrual for unbilled revenue.

     Concurrently with the merger, the Company entered into agreements with the
stockholders to lease office space used in the Company's operations for a
negotiated amount and term.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders of
J.A. Croson Company and Franklin Fire Sprinkler Company:

     We have audited the accompanying combined balance sheets of J.A. Croson
Company and Franklin Fire Sprinkler Company (combined, the Company) as of
September 30, 1997 and 1998, and March 31, 1999, and the related combined
statements of operations, cash flows and stockholders' equity for each of the
three years in the period ended September 30, 1998, and for the six months ended
March 31, 1999. These combined financial statements are the responsibility of
the Companies' management. Our responsibility is to express an opinion on these
combined 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 combined financial statements referred to above present
fairly, in all material respects, the combined financial position of J.A. Croson
Company and Franklin Fire Sprinkler Company as of September 30, 1997 and 1998,
and March 31, 1999, and the combined results of their operations and their cash
flows for each of the three years in the period ended September 30, 1998, and
for the six months ended March 31, 1999, in conformity with generally accepted
accounting principles.

            J.A. CROSON COMPANY AND FRANKLIN FIRE SPRINKLER COMPANY

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

     J.A. Croson Company (Croson), an Ohio corporation, provides plumbing and
mechanical contracting services for commercial and industrial entities primarily
in Ohio. Franklin Fire Sprinkler Company (Franklin) provides fire protection
contracting services for commercial and industrial entities throughout Ohio. The
lengths of construction contracts are typically less than one year. Croson and
Franklin are collectively referred to herein as the Company.

     The Company and its stockholders intend to enter into a definitive
agreement with American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which
all outstanding shares of the Company's common stock will be exchanged for cash
and shares of AMPAM common stock concurrently with the consummation of the
related financing.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Principles of Combination

     The accompanying financial statements include the accounts of Croson and
Franklin which are affiliated through common ownership. Intercompany
transactions and balances have been eliminated in combination.

  Interim Financial Information

     The interim financial statements for the six months ended March 31, 1998,
are unaudited and have been prepared pursuant to the rules and regulations of
the Securities and Exchange Commission. Accordingly, they do not include all of
the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of the Company's
management, the unaudited interim financial statements contain all adjustments
(consisting of normal recurring adjustments) considered necessary for a fair
presentation. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  Accounts Receivable and Provision for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances.

  Inventories

     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and

                                      F-80
<PAGE>   206
            J.A. CROSON COMPANY AND FRANKLIN FIRE SPRINKLER COMPANY

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

depreciated. Upon retirement or disposition of property and equipment, the cost
and related accumulated depreciation are removed from the accounts and any
resulting gain or loss is recognized in the statement of operations.

  Revenue Recognition

     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of cost incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor and depreciation
costs. Provisions for the total estimated losses on uncompleted contracts are
made in the period in which such losses are determined. Changes in job
performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.

     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.

     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.

  Income Taxes

     The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company itself is not subject to taxation for federal
purposes. Under S Corporation status, the stockholders report their share of the
Company's taxable earnings in their personal tax returns. Consequently, the
accompanying financial statements of the Company do not include a provision for
current or deferred income taxes. Certain municipalities do not recognize the S
Corporation status for purposes of local taxation. The provision for income
taxes in the accompanying statement of operations represents the local tax
provision related to such municipalities. The Company will terminate its S
Corporation status concurrently with the effective date of the merger (see Note
12).

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provision of Statement of Financial Accounting
Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed of." Accordingly, in the event that
facts and circumstances indicate that property and equipment or other assets may
be impaired, an evaluation of recoverability would be performed. If an
evaluation is

                                      F-81
<PAGE>   207
            J.A. CROSON COMPANY AND FRANKLIN FIRE SPRINKLER COMPANY

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

required, the estimated future undiscounted cash flows associated with the asset
are compared to the asset's carrying amount to determine if an impairment of
such property is necessary. The effect of any impairment would be to expense the
difference between the fair value of such property and its carrying value.
Adoption of this standard did not have a material effect on the financial
position or results of operations of the Company.

  Reclassifications

     Certain reclassifications have been made to the prior year financial
statements to conform with the current year presentation.

9. FINANCIAL INSTRUMENTS:

     The Company's financial instruments consist of cash and cash equivalents

instruments on the accompanying combined balance sheets approximates their fair
value.

10. COMMITMENTS AND CONTINGENCIES:

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant claims or losses on any of these insurance policies.

11. MAJOR CUSTOMERS AND RISK CONCENTRATION:

     The Company had revenues of approximately 26.8%, 32.2% and 31.2% of total
revenues to one major customer during the years ended September 30, 1996, 1997
and 1998, respectively. The Company had revenues of approximately 35.8% of total
revenues to one major customer during the six month period ended March 31, 1999.

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is, by law, granted a lien interest in the
work until paid. The Company is exposed to potential credit risk related to
changes in business and economic factors within the region. However,

                                      F-85
<PAGE>   211
            J.A. CROSON COMPANY AND FRANKLIN FIRE SPRINKLER COMPANY

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

management believes that its contract acceptance, billing and collection
policies are adequate to minimize the potential credit risk.

12. SUBSEQUENT EVENT:

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash and stock of AMPAM, after which the Company is a
wholly owned subsidiary of AMPAM.

     In connection with the merger, the Company sold or distributed certain
nonoperating assets and attendant liabilities, if any, to the stockholders.
Additionally, the Company made cash distributions which represent the Company's
estimated S Corporation accumulated adjustment account.

     As discussed in Note 2, in connection with the merger, the Company
converted from an S Corporation to a C Corporation. Upon conversion to C
Corporation status, the Company recorded deferred taxes for which it will be
responsible. If the S Corporation had been terminated as of September 30, 1998,
the Company would have recorded a deferred tax asset of approximately $99,000
due to differences between book and tax depreciation. If the S Corporation had
been terminated as of March 31, 1999, the Company would have recorded a deferred
tax liability of approximately $133,000 due to differences between book and tax
depreciation.

     Concurrently with the merger, the Company entered into agreements with the
stockholders to lease office space used in the Company's operations for a
negotiated amount and term.

Company's management. Our responsibility is to express an opinion on these

     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

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 J. A. Croson Company of

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION

     J. A. Croson Company of Florida (the Company), a Florida corporation,
focuses on providing plumbing contractor services primarily for multi-family
housing developers. The Company performs the majority of its contract work under
fixed-price contracts, with contract terms generally less than one year. The
Company performs the majority of its work in Central Florida.

     The Company and its stockholders intend to enter into a definitive
agreement with American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which
all outstanding shares of the Company's common stock will be exchanged for cash
and shares of AMPAM common stock concurrently with the consummation of the
related financing.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Interim Financial Information

     The interim financial statements for the three months ended March 31, 1998,
are unaudited and have been prepared pursuant to the rules and regulations of
the Securities and Exchange Commission. Accordingly, they do not include all of
the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of the Company's
management, the unaudited interim financial statements contain all adjustments
(consisting of normal recurring adjustments) considered necessary for a fair
presentation. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  Provision for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances.

  Inventories

     Inventory purchases have historically been charged to jobs when purchased.
Inventories consist of parts and supplies held for use in the ordinary course of
business and are stated at the lower of cost or market using the first-in,
first-out (FIFO) method.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets,
net of any salvage values.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.

                        J. A. CROSON COMPANY OF FLORIDA

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Revenue Recognition

     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of cost incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor and depreciation
costs. Provisions for the total estimated losses on uncompleted contracts are
made in the period in which such losses are determined. Changes in job
performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.

     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.

     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.

  Warranty Costs

     For most contracts, the Company warrants labor and materials for one year
after completion of the job.

  Income Taxes

     The Company has elected S corporation status, as defined by the Internal
Revenue Code, whereby the Company itself is not subject to taxation for federal
purposes. Under S corporation status, the stockholders report their shares of
the Company's taxable earnings or losses in their personal tax returns.
Consequently, the accompanying financial statements of the Company do not
include a provision for current or deferred federal taxes. The Company
terminated its S corporation status concurrently with the effective date (April
1, 1999) of the merger discussed in Note 13.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
Accordingly, in the event that facts and circumstances indicate that property
and equipment or other assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if an impairment of such property is necessary. The
effect of any impairment would be to expense the difference between
                                      F-93

the fair value of such property and its carrying value. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

     The Company has also entered into a Stock Redemption Agreement with a
principal shareholder, agreeing to repurchase all of his stock over a period of
years, with the first redemption date being no earlier than January 1, 1998. The
redemption date shall be determined by the mutual agreement of the stockholder
and the Company before December 31 of the preceding year. The agreement requires
the Company to purchase annually from the stockholder the number of shares equal
to 10% (on a fully diluted basis immediately following the redemption) of the
total number of issued and outstanding shares as of the redemption date. The
purchase price of these shares shall be payable in cash and shall be equal to
10% of the book value of the Company on the redemption date. As of May 26, 1999,
no repurchase has occurred.

8. RELATED-PARTY TRANSACTIONS

     The Company leases CERTAIN property and office space from a stockholder
under a noncancelable operating lease (see Note 6). The rent approximates the
fair market value of the property.

     The Company had a Subordinated Note Agreement with a stockholder, with a
balance of $434,000 at December 31, 1997. This note was repaid during 1998.

     At December 31, 1997 and 1998 and March 31, 1999, the Company had $80,000,
$179,000 and $4,000, respectively, of advances to employees included in current
assets. The 1998 amount includes a balance of $125,000 due from a principal
shareholder of the Company.

     During the years ended December 31, 1996 and 1997, the Company purchased
plumbing supplies of $81,000 and $48,000, respectively, from a company
affiliated through common ownership. No such purchases have been made since
January 1, 1998. No amounts were owed to the Company at December 31, 1997 and
1998, or March 31, 1999.

9. EMPLOYEE BENEFIT PLAN

     The Company has a defined contribution profit-sharing plan. The plan
provides for the Company to match 50% of the first $1,200 contributed by each
employee. Total contributions by the Company under the plan were approximately
$11,000, $23,000, and $26,000 for the years ending December 31, 1996, 1997 and
1998, respectively and $14,000 for the three months ended March 31, 1999.

10. FINANCIAL INSTRUMENTS

     The Company's financial instruments consist of cash and cash equivalents, a
line of credit, notes payable and debt. The Company believes that the carrying
value of these instruments on the accompanying balance sheets approximates their
fair value.

11. COMMITMENTS AND CONTINGENCIES

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of SUCH
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including workers'
compensation, general liability, and an umbrella policy. The Company has not
incurred significant claims or losses on any of these insurance policies.

12. MAJOR CUSTOMERS AND RISK CONCENTRATION

     The Company had revenues of approximately 29%, 27% and 24% of total
revenues to three major customers during the years ended December 31, 1996,
1997, and 1998, respectively and 42% during the three months ended March 31,
1999.

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is, by law, granted a lien interest in the
work until paid. The Company is exposed to potential credit risk related to
changes in business and economic factors within the region. However, management
believes that its contract acceptance, billing and collection policies are
adequate to minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas which it operates.

13. SUBSEQUENT EVENTS

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash and stock of AMPAM, after which the Company is a
wholly owned subsidiary of AMPAM.

     In connection with the merger, the Company sold or distributed certain
non-operating assets and attendant liabilities, if any, to the stockholders.
Additionally, the Company made cash distributions which represent the Company's
estimated S corporation accumulated adjustments account.

     As discussed in Note 2, in connection with the merger, the Company
converted from an S corporation to a C corporation. Upon conversion to C
corporation status, the Company recorded deferred taxes for which it will be
responsible. If the S corporation had been terminated as of December 31, 1998,
the Company would have recorded a deferred tax asset of approximately $30,000
due to differences between

book and tax depreciation. If the S corporation had been terminated as of March
31, 1999, the Company would have recorded a deferred tax asset of approximately
$15,600 due to bad debt allowance and a deferred tax liability of approximately
$7,500 due to the difference between book and tax depreciation.

     Concurrently with the merger, the Company entered into agreements with the
stockholders to lease land and buildings used in the Company's operations for a
negotiated amount and term.

                     POWER PLUMBING, INC., AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

     Power Plumbing, Inc., a Delaware corporation, and its subsidiaries (the
Company) focus on providing plumbing construction services primarily for
multifamily residential buildings. The Company performs the majority of its
contract work under fixed-price contracts, with contract terms generally ranging
from six to 18 months. The Company performs the majority of its work in Texas.

     On April 1, 1999, American Plumbing & Mechanical, Inc. (AMPAM) acquired
through merger all the stock of the Company in exchange for cash and stock of
AMPAM, after which the Company is a wholly owned subsidiary of AMPAM. In
connection with the merger, the Company sold or distributed certain nonoperating
assets and attendant liabilities, if any, to the stockholders.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Principles of Consolidation

     The financial statements through December 31, 1998 include the accounts and
results of operations of the Company, its wholly owned subsidiary, Power
Plumbing Personnel, Inc., and an affiliated company, Bingle Partners, Ltd. (see
Note 8), which is under common control and management. Effective January 1,
1999, the Company sold its interest in Bingle Partners, Ltd. to the stockholders
of the Company; therefore the financial statements for periods presented
subsequent to December 31, 1998 include only the accounts and results of
operations of the Company and its wholly owned subsidiary, Power Plumbing
Personnel, Inc. All significant intercompany transactions and balances have been
eliminated in consolidation.

  Interim Financial Information

     The interim financial statements for the three months ended March 31, 1998,
are unaudited and have been prepared pursuant to the rules and regulations of
the Securities and Exchange Commission. Accordingly, they do not include all of
the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of the Company's
management, the unaudited interim financial statements contain all adjustments
(consisting of normal recurring adjustments) considered necessary for a fair
presentation. The results of operations for the interim period are not
necessarily indicative of the results for the entire fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  Accounts Receivable and Allowance for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
lease or the estimated useful life of the asset (see Note 4).

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated over the
remaining useful life. Upon retirement or disposition of property and equipment,
the

                     POWER PLUMBING, INC., AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

cost and related accumulated depreciation are removed from the accounts and any
resulting gain or loss is recognized in accompanying consolidated statements of
operations.

  Revenue Recognition

     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of cost incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor and depreciation
costs. Provisions for the total estimated losses on uncompleted contracts are
made in the period in which such losses are determined. Changes in job
performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income and their effects are
recognized in the period in which the revisions are determined.

     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the Company anticipates that the retention
balance at each balance sheet date will be collected within the subsequent
fiscal year.

     The current asset "Costs and estimated earnings in excess of billing on
uncompleted contracts" represents revenues recognized in excess of amounts
billed. The current liability "Billings in excess of costs and estimated
earnings on uncompleted contracts" represents billings in excess of revenues
recognized.

  Warranty Costs

     The Company warrants labor and materials for the first year after
completion of plumbing construction. A reserve for warranty costs is recorded
based upon the historical level of warranty claims and management's estimate of
future costs.

  Income Taxes

     The Company, which is a C Corporation, follows the liability method of
accounting for income taxes in accordance with Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting for Income Taxes." Under this method,
deferred assets and liabilities are recorded for future tax consequences of
temporary differences between the financial reporting and tax bases of assets
and liabilities and are measured using the enacted tax rules and laws that will
be in effect when the underlying assets or liabilities are recovered or settled.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
Accordingly, in the event that facts and circumstances indicate that property
and equipment or other assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

flows associated with the asset are compared to the asset's carrying amount to
determine if an impairment of such property is necessary. The effect of any
impairment would be to expense the difference between the fair value of such
property and its carrying value. The adoption of this standard did not have a
material effect on the financial position or results of operations of the
Company.

5. LINE OF CREDIT AND LONG-TERM DEBT:

     The Company has a $150,000 revolving line of credit with a bank which is
due on demand or, if no demand, expires May 1, 1999, and bears interest at 0.5
percent above the bank's base lending rate. At December 31, 1997 and 1998 and
March 31, 1999, no balance was outstanding under this line of credit. This line
of credit is collateralized by the Company's accounts receivable and equipment
as well as insurance on its president and a personal unlimited guarantee from
the president. The line of credit was cancelled subsequent to March 31, 1999.

     Long-term debt at December 31, 1998, consisted of a note payable with a
balance of approximately $71,000 to a bank for the purchase of property by
Bingle Partners, Ltd. The note was included in the Company's sale of its
interest in Bingle Partners, Ltd. interest; therefore, the Company has no
long-term debt at March 31, 1999.

6. LEASES:

     During 1998, the Company leased two vehicles for stockholders, which expire
in April 2001 and September 2001. Expense for the vehicle leases was $4,980,
$11,113 and $12,490 for the years ended December 31, 1997 and 1998 and the three
months ended March 31, 1999, respectively.

     The Company has an agreement with Bingle Partners, Ltd., that as of January
1, 1999 was owned by stockholders of the Company, to lease office space at a
rate that, in management's opinion, approximated market. The lease expires
August 31, 2003. Expense for the lease was $7,950 for the three months ended
March 31, 1999. Future minimum lease payments under these noncancelable
operating leases are as follows (in thousands):

8. RELATED-PARTY TRANSACTIONS:

     In December 1996, the Company purchased a 97 percent limited partnership
interest in Bingle Partners, Ltd., from a former stockholder for $300,000. A
stockholder owns a majority interest in the company that is the 3 percent
general partner in Bingle Partners, Ltd. On January 1, 1999, the Company sold
its interest in Bingle Partners, Ltd., to the stockholders of the Company in
exchange for promissory notes from each stockholder. The notes receivable had a
balance of approximately $396,000 at March 31, 1999. Subsequent to March 31,
1999, the Company collected the full amount of the receivable. The Company
leases office space from Bingle Partners, Ltd. (see Note 6).

     In June 1998, the Company entered into a financing arrangement with ICM,
Inc., whereby the Company began purchasing materials for and selling them to
ICM, Inc., at a nominal markup. One of the Company's stockholders (the ICM
Stockholder) has a majority ownership in ICM Notes, Ltd., a company that also
provides financing to ICM, Inc. ICM Notes, Ltd., and ICM, Inc., do not have
common ownership. The ICM Stockholder has an informal agreement with the other
stockholders of the Company which provides that any losses incurred as a result
of the financing arrangement between the Company and ICM, Inc., will be funded
by the ICM Stockholder. As a result of this arrangement, approximately $200,000
of accounts receivable was included as other accounts receivable in the
accompanying balance sheets at December 31, 1998 and March 31, 1999. At the end
of 1998, ICM, Inc., ceased operations, and, subsequent to March 31, 1999, the
Company collected such receivable from the ICM Stockholder.

     In June 1998, the Company guaranteed certain long-term obligations of four
employees. The long-term obligations consist of four notes payable to Northwest
Bank, N.A., for the purchase of vehicles. The notes are secured by the vehicles.

9. EMPLOYEE BENEFIT PLAN:

     The Company has a defined contribution profit-sharing plan. The plan
provides for discretionary contributions by the Company as determined by the
stockholders. Total contributions by the Company under the plan were
approximately $14,216 and $14,690 for the years ended December 31, 1997 and
1998, respectively. No contributions were made by the Company under the plan for
the three months ended March 31, 1999. Such contributions are included in
accounts payable and accrued expenses in the accompanying consolidated balance
sheets at December 31, 1997 and 1998.

10. FINANCIAL INSTRUMENTS:

     The Company's financial instruments consist of cash and cash equivalents, a
line of credit and debt. The Company believes that the carrying values of these
instruments on the accompanying consolidated balance sheets approximate their
fair value.

11. COMMITMENTS AND CONTINGENCIES:

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant claims or losses on any of these insurance policies.

12. MAJOR CUSTOMERS AND RISK CONCENTRATION:

     During the years ended December 31, 1997 and 1998 and the three months
ended March 31, 1999, three customers accounted for more than 10 percent of
total revenues. Sales to these companies were as follows (in thousands):

     During the year ended December 31, 1997, three vendors accounted for more
than 10 percent of the Company's total materials purchases, and for the year

</TABLE>

     Management believes that the materials are readily available in the
marketplace at prices which approximate those paid to the above vendors.

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is, by law, granted a lien interest in the
work until paid. The Company is exposed to potential credit risk related to
changes in business and economic factors in Texas. However, management believes
that its contract acceptance, billing and collection policies are adequate to
minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas which it operates.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Nelson Mechanical Contractors, Inc.:

     We have audited the accompanying balance sheets of Nelson Mechanical
Contractors, Inc. as of April 30, 1998, and March 31, 1999, and the related
statements of operations, cash flows, and stockholders' equity for the years
ended April 30, 1997 and 1998, and for the eleven months ended March 31, 1999.
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.

corporation, focuses on providing plumbing and utility services primarily for
general contractors, developers, local governmental agencies, and private
institutions. The Company performs the majority of its contract work under
fixed-price contracts, with contract terms generally ranging from two months to
two years. The Company performs the majority of its work in the southeast United
States.

     The Company and its stockholders intend to enter into a definitive
agreement with American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which
all outstanding shares of the Company's common stock will be exchanged for cash,
notes and shares of AMPAM common stock concurrently with the consummation of the
related financing.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Revenue Recognition

     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized using the percentage-of-completion method, measured by
the percentage of cost incurred to date to total estimated costs for each
contract. Contract costs include all direct material and labor costs and those
indirect costs related to contract performance, such as indirect labor and
depreciation costs. Provisions for the total estimated losses on uncompleted
contracts are made in the period in which such losses are determined. Changes in
job performance, job conditions, estimated profitability, and final contract
settlements may result in revisions to costs and income, and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.

     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year. Customer retainage is
included in accounts receivable from construction contracts in the accompanying
balance sheets.

     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents. As noted in
Note 5, cash and cash equivalents include $222,000 and $233,000 of restricted
cash at April 30, 1998, and March 31, 1999, respectively.

  Accounts Receivable and Provision for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based on its
historical collection experience with its plumbing and utility services
customers. Management believes that an allowance for doubtful accounts is not
necessary, based on the status of contracts and their review of accounts.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Inventories

     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.

  Warranty Costs

     For most contracts, the Company warrants labor and materials for one year
after completion of the job. A reserve for warranty costs is recorded based on
the historical level of warranty claims and management's estimate of future
costs.

  Income Taxes

     The Company has elected S corporation status, as defined by the Internal
Revenue Code, whereby the Company itself is not subject to taxation for federal
purposes. Under S corporation status, the stockholders report their shares of
the Company's taxable earnings or losses in their personal tax returns. The
Company will continue to be liable for income tax currently due to states that
do not recognize S corporation status. At April 30, 1998, and March 31, 1999,
there were no material income taxes due to such states.

     An S corporation is permitted under the Revenue Act of 1987 to retain its
fiscal year, rather than adopting the calendar year, for tax purposes. However,
an annual payment approximating the income tax that would be paid on
short-period income if there had been a switch to a calendar year must be paid.
This tax deposit is reported as "other assets" in the accompanying financial
statements, is adjusted annually and amounts to $530,024 at April 30, 1998, and
March 31, 1999. The tax deposit is realized when the entity switches to a
calendar year, liquidates, terminates its S status or is considered not to have
any deferred taxable income. The Company terminated its S corporation status on
April 1, 1999, which is the effective date of the merger discussed in Note 11.

     At April 30, 1998, and March 31, 1999, the Company had available for state
income tax purposes net operating loss carryforwards of approximately $550,000
which expire through 2011.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements,
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of Statement of Financial Accounting
Standards ("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed Of." Accordingly, in the event that
facts and circumstances indicate that property and equipment or other assets may
be impaired, an evaluation of recoverability would be performed. If an
evaluation is required, the estimated future undiscounted cash flows associated
with the asset are compared to the asset's carrying amount to determine whether
an impairment of such property is necessary. The effect of any impairment would
be to expense the difference between the fair value of such property and its
carrying value. Adoption of this standard did not have a material effect on the
financial position or results of operations of the Company.

5. REVOLVING LINE OF CREDIT, LETTER OF CREDIT, AND DEBT

     The Company has a $500,000 revolving line of credit with a financial
institution, secured by all owned equipment. The line of credit matures on
January 8, 2000, with the outstanding balance being due at this time. The line
of credit bears interest at the prime rate, which was 7.75% at March 31, 1999,
and is paid quarterly on the outstanding balance during the period. At April 30,
1998, and March 31, 1999, the Company did not have an outstanding balance on the
line of credit. The line of credit was terminated subsequent to March 31, 1999.

     The Company has a $250,000 letter of credit with a financial institution,
secured by assignment of a certificate of deposit in the amount of $222,000 and
$233,000 at April 30, 1998, and March 31, 1999, respectively. The letter of
credit was reduced to $150,000 subsequent to March 31, 1999.

     The Company occasionally borrows from its stockholders, as discussed in
Note 7. These notes are payable on demand and bear interest at 7%. At April 30,
1998, and March 31, 1999, the outstanding balance on loans from its stockholders
was $99,000 and $4,788,000, respectively.

     The Company does not have any long-term debt instruments.

6. LEASES

7. RELATED-PARTY TRANSACTIONS

     The Company occasionally loans money to its stockholders, which is payable
on demand. The loans bear interest at the applicable federal rate (5.51% at
April 30, 1998). There were no such loans at March 31, 1999.

     The Company occasionally borrows money from its stockholders, which is
payable on demand. The loans bear interest at 7%.

     The Company rents certain real property from its majority stockholder on a
month-to-month basis (see Note 6). Management believes the rent paid
approximates the fair market value of the property.

     The Company loaned $90,000 to a stockholder under an installment agreement
on April 1, 1996. The note bears interest at 7% and is payable in monthly
installations of $809, including interest through April 2011. Current maturities
of the loan at April 30, 1998, was $4,000. The loan was paid in full on
September 30, 1998.

8. FINANCIAL INSTRUMENTS

     The Company's financial instruments consist of cash and cash equivalents,
notes receivable and notes payable. The Company believes that the carrying value
of these instruments on the accompanying balance sheets approximates their fair
value.

9. COMMITMENTS AND CONTINGENCIES

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe that the outcome of
such legal actions will have a material adverse effect on the Company's
financial position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability, and an umbrella policy. The Company has not
incurred significant claims or losses on any of these insurance policies.

10. MAJOR CUSTOMERS AND RISK CONCENTRATION

     The Company had sales of approximately 17.8 percent and 11.5 percent of
total sales to one major customer during the year ended April 30, 1997. The
Company had sales of approximately 23.0 percent and

                      NELSON MECHANICAL CONTRACTORS, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

33.3 percent of total sales to another major customer during the year ended
April 30, 1998, and the eleven months ended March 31, 1999, respectively.

     In general, the Company performs its services under contract terms that
entitle it to progress payments, and the Company is, by law, granted a lien
interest in the work until paid. The Company is exposed to potential credit risk
related to changes in business and economic factors within the market. However,
management believes that its contract acceptance, billing, and collection
policies are adequate to minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas which it operates.

11. SUBSEQUENT EVENTS

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash, notes and stock of AMPAM, after which the Company
is a wholly owned subsidiary of AMPAM.

     In connection with the merger, the Company sold or distributed certain
non-operating assets and attendant liabilities, if any, to the stockholders.
Additionally, the Company made cash distributions which represent the Company's
estimated S Corporation accumulated adjustment account.

     As discussed in Note 2, in connection with the merger, the Company
converted from an S corporation to a C corporation. Upon conversion to C
corporation status, the Company recorded deferred taxes for which it will be
responsible. If the S corporation had been terminated as of April 30, 1998, the
Company would have recorded a deferred tax asset of approximately $4,500 due to
bad debt allowance and a deferred tax liability of approximately $47,000 due to
differences between book and tax depreciation.

     Concurrently with the merger, the Company entered into agreements with the
stockholder(s) to lease land and buildings used in the Company's operations for
a negotiated amount and term.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Sherwood Mechanical, Inc.:

     We have audited the accompanying balance sheets of Sherwood Mechanical,
Inc. (a California corporation), as of September 30, 1997 and 1998, and the
related statements of operations, cash flows and stockholder's equity for the
years 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 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 Sherwood Mechanical, Inc. as
of September 30, 1997 and 1998 and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS

(1) BUSINESS AND ORGANIZATION:

     Sherwood Mechanical, Inc., a California corporation (the Company), focuses
on installation of plumbing, mechanical, and site utilities for commercial and
industrial construction projects. The Company performs the majority of its
contract work under fixed price contracts with contract terms generally ranging
from 12 to 24 months. The Company performs the majority of its work in
California, Arizona and Nevada.

     The Company and its stockholder intend to enter into a definitive agreement
with American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash,
notes and shares of AMPAM common stock concurrently with the consummation of the
related financing.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Interim Financial Information

     The interim financial statements as of March 31, 1999 and for the six
months ended March 31, 1998 and 1999, are unaudited and have been prepared
pursuant to the rules and regulations of the Securities and Exchange Commission.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of the Company's management, the unaudited interim financial
statements contain all adjustments (consisting of normal recurring adjustments)
considered necessary for a fair presentation. The results of operations for the
interim periods are not necessarily indicative of the results for the entire
fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  Accounts Receivable and Allowance for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances.

  Inventories

     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Revenue Recognition

     The Company recognizes revenues when services are performed, except when
work is being performed under a construction contract. Revenues from
construction contracts are recognized on the percentage-of-completion method
measured by the percentage of cost incurred to date to total estimated costs for
each contract. Contract costs include all direct material and labor costs and
those indirect costs related to contract performance, such as indirect labor and
depreciation costs. Provisions for the total estimated losses on uncompleted
contracts are made in the period in which such losses are determined. Changes in
job performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.

     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.

     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized under the percentage of completion.

  Warranty Costs

     The Company warrants labor for generally one year after construction is
complete. A reserve for warranty costs is recorded based upon the historical
level of warranty claims and management's estimate of future costs, which are
not expected to be material.

  Income Taxes

     The Company, which is a C Corporation, follows the liability method of
accounting for income taxes in accordance with Statement of Financial Accounting
Standards (SFAS) No. 109, Accounting for Income Taxes. Under this method,
deferred assets and liabilities are recorded for future tax consequences of
temporary 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 underlying assets or liabilities are recovered or settled.
Historically, the Company used the completed-contract method of reporting for
income tax purposes, under which all contract revenues and expenses are
recognized in the accounting period in which the contract is completed. The
Company changed to the percentage of completion method for income tax purposes
for the year beginning October 1, 1997.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.
Accordingly, in the event that facts and
                                      F-129

circumstances indicate that property and equipment or other assets may be
impaired, an evaluation of recoverability would be performed. If an evaluation
is required, the estimated future undiscounted cash flows associated with the
asset are compared to the asset's carrying amount to determine if an impairment
of such property is necessary. The effect of any impairment would be to expense
the difference between the fair value of such property and its carrying value.
Adoption of this standard did not have a material effect on the financial
position or results of operations of the Company.

(9) RELATED-PARTY TRANSACTIONS:

     The Company entered into a construction contract with a partnership in
which the partners are executive officers and a stockholder of the Company. The
total contract receivable balance as of September 30, 1997 and 1998 was
approximately $302,000 and $88,000, respectively. The Company recorded
construction revenue and gross margin for this contract of approximately
$457,000 and $23,000 for 1997, and approximately $475,000 and $(112,000) for
1998, respectively.

(10) EMPLOYEE BENEFIT PLAN:

     The Company has a defined contribution profit-sharing plan. The plan
provides for the Company to match an unspecified percent contributed by each
employee at the discretion of the Board of Director. Total cash contributions by
the Company under the plan were approximately $68,000 and $100,000 for the year
ended September 30, 1997 and 1998, respectively. Vesting is 100% at date of
contribution for employee contributions and employer contributions generally
vest over a period of one to six years.

(11) FINANCIAL INSTRUMENTS:

     The Company's financial instruments consist of cash and cash equivalents,
contracts receivable, accounts payable, lines of credit, notes payable and
long-term debt. The Company believes that the carrying value of these
instruments on the accompanying balance sheets approximates their fair value.

(12) COMMITMENTS AND CONTINGENCIES:

  Litigation

     The Company was named as a defendant in an action filed by the trustee of a
union apprenticeship committee in December 1997, alleging the Company violated
the State's prevailing wage law and is seeking damages totaling approximately
$269,000. Related to the same matter, the Division of Labor Standards
Enforcement has sued an unaffiliated third party (Ray Wilson Company) seeking
the wages stated above of $269,000 plus penalties of $293,000. Ray Wilson
Company is seeking indemnification from the Company. The two cases overlap and
the collective potential loss totals $562,000. Subsequent to year end, the sole
stockholder of the Company personally guaranteed any liability to the Company
related to this matter. In March of 1999, the Department of Labor Standards
Enforcement offered a settlement of approximately $400,000. In April 1999, the
sole stockholder of the Company offered a settlement of approximately $270,000.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant claims or losses on any of these insurance policies.

(13) MAJOR CUSTOMERS AND RISK CONCENTRATION:

     The Company had revenue greater than 10 percent of total revenues from
three major customers during the year ended September 30, 1997 and one major
customer during the year ended September 30, 1998, as follows (in thousands):

</TABLE>

     For the year ended September 30, 1997, contracts receivable from the three
customers were approximately $133,000, $131,000 and $77,000 for customers A, B
and C, respectively. Contracts receivable at September 30, 1998, from Customer A
was approximately $1,020,000.

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is granted a lien interest in the work until
paid. The Company is exposed to potential credit risk related to changes in
business and economic factors within the market. However, management believes
that its contract acceptance, billing and collection policies are adequate to
minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas which it operates.

(14) EVENT SUBSEQUENT TO DATE OF REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
(UNAUDITED):

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash, notes and stock of AMPAM, after which the Company
is a wholly owned subsidiary of AMPAM.

     In connection with the merger, the Company distributed certain assets to
the shareholder, consisting of land, buildings and automobiles, at carrying
value.

     Concurrently with the merger, the Company entered into agreements with the
stockholder to lease land and buildings used in the Company's operations for a
negotiated amount and term.

                      MILLER MECHANICAL CONTRACTORS, INC.

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

     Miller Mechanical Contractors, Inc. (the Company), a Georgia corporation,
is a plumbing subcontractor primarily for extended-stay motels and large upscale
apartment complexes. The Company performs the majority of its contract work
under fixed-price contracts, with contract terms generally ranging from six to
18 months. The Company performs the majority of its work in Georgia, Florida,
North Carolina, South Carolina and Tennessee.

     The Company and its stockholders intend to enter into a definitive
agreement with American Plumbing & Mechanical, Inc. (AMPAM), pursuant to which
all outstanding shares of the Company's common stock will be exchanged for cash,
notes and shares of AMPAM common stock concurrently with the consummation the
related financing.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Interim Financial Information

     The interim financial statements for the six months ended March 31, 1998,
are unaudited and have been prepared pursuant to the rules and regulations of
the Securities and Exchange Commission. Accordingly, they do not include all of
the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of the Company's
management, the unaudited interim financial statements contain all adjustments
(consisting of normal recurring adjustments) considered necessary for a fair
presentation. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  Accounts Receivable and Provisions for Doubtful Accounts

     The Company provides an allowance for doubtful accounts based upon an
estimate of uncollectable balances. Management believes that an allowance for
doubtful accounts is not necessary, based on the status of contracts and review
of accounts.

  Inventories

     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
weighted-average method.

  Property and Equipment

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the assets (see Note 4).
Expenditures for repairs and maintenance are charged to expense when incurred.
Expenditures for major renewals and betterments, which extend the useful lives
of existing equipment, are capitalized and depreciated. Upon retirement or
disposition of property and equipment, the cost and related accumulated

  Revenue Recognition

     The Company recognizes revenue when services are performed, except when
work is being performed under a construction contract. Revenues from
construction contracts are recognized using the percentage-of-completion method
measured by the percentage of cost incurred to date to total estimated costs for
each contract. Contract costs include all direct material and labor costs and
those indirect costs related to contract performance, such as indirect labor and
depreciation costs. Provisions for the total estimated losses on uncompleted
contracts are made in the period in which such losses are determined. Changes in
job performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income, and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.

     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.

     The current asset "Costs and estimated earnings in excess of billings on
uncompleted contracts" represents revenues recognized in excess of amounts
billed. The current liability "Billings in excess of costs and estimated
earnings on uncompleted contracts" represents billings in excess of revenues
recognized.

  Income Taxes

     The Company, which is a C Corporation, follows the liability method of
accounting for income taxes in accordance with Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting for Income Taxes." Under this method,
deferred assets and liabilities are recorded for future tax consequences of
temporary 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 underlying assets and liabilities are recovered or
settled.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from the estimates.

  Realization of Long-Lived Assets

     The Company has adopted the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
Accordingly, in the event that facts and circumstances indicate that property
and equipment or other assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine whether an impairment of such property is
necessary. The effect of any impairment would be to expense the difference
between the fair value of such property and its carrying value. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

8. RELATED-PARTY TRANSACTIONS:

     The Company has purchased certain materials and supplies from an affiliate.
The Company also bills certain salaries, insurance and office supplies to the
affiliate. The Company and the affiliate have a common stockholder. For the
years ended September 30, 1997 and 1998 and the six months ended March 31, 1999,
the Company purchased approximately $1,940,000, $3,048,000 and $1,044,000,
respectively, of material and supplies from the affiliate. At September 30, 1997
and 1998 and March 31, 1999, the Company had receivables of $195,334, $8,241 and
$63, respectively due from the affiliate.

     The Company leases all of its operating facilities from the majority
stockholder (see Note 6).

9. EMPLOYEE BENEFIT PLAN:

     The Company has a defined contribution profit-sharing plan qualifying under
Section 401(a) of the Internal Revenue Code. The plan covers all eligible
employees. The Company can elect to contribute specified amounts to the plan, as
determined by the board of directors. Participants' vested interests in the
Company's contributions are based on years of service, as defined, with the
Company. The Company contributed $240,000, $130,000 and $65,000 to the plan for
the years ended September 30, 1997 and 1998,

and for the six months ended March 31, 1999, respectively, which is included in
accounts payable and accrued expenses in the accompanying balance sheets.

10. FINANCIAL INSTRUMENTS:

     The Company's financial instruments consist of cash and cash equivalents, a
line of credit and debt. The Company believes that the carrying value of these
instruments on the accompanying balance sheet approximates their values.

11. COMMITMENTS AND CONTINGENCIES:

  Litigation

     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  Insurance

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant claims or losses on any of these insurance policies.

12. MAJOR CUSTOMERS AND RISK CONCENTRATION:

     The Company had sales of approximately 54 percent of total sales to one
major customer during the year ended September 30, 1997. The Company had sales
of approximately 63 percent and 13 percent, respectively to two major customers
during the year ended September 30, 1998 and sales of approximately 56 percent
and 11 percent to two major customers during the six months ended March 31,
1999.

     In general, the Company performs its services under contract terms that
entitle it to progress payments and is, by law, granted a lien interest in the
work until paid. The Company is exposed to potential credit risk related to
changes in business and economic factors within the southeastern United States.
However, management believes that its contract acceptance, billing and
collection policies are adequate to minimize the potential credit risk.

     The Company's customers are primarily in the construction industry.
Accordingly, the Company is exposed to risks of fluctuations in construction in
the areas which it operates.

13. SUBSEQUENT EVENT:

     On April 1, 1999, AMPAM acquired through merger all the stock of the
Company in exchange for cash, notes and stock of AMPAM, after which the Company
is a wholly owned subsidiary of AMPAM.

     In connection with the merger, the Company sold or distributed certain
nonoperating assets and attendant liabilities, if any, to the stockholders.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. 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 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 (1) for any breach of the director's duty of loyalty to the corporation
or its stockholders, (2) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (3) under Section
174 of the Delaware General Corporation Law, or (4) for any transaction from
which the director derived an improper personal benefit.

                                      II-1
<PAGE>   274

     Section 7(d) of the Company's Amended and Restated Certificate of
Incorporation states that:

     A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit. 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. Any repeal or modification of this Section 7(d) by the
stockholders of the Corporation shall be prospective only, and shall not
adversely affect any limitation on the personal liability of a director of the
Corporation existing at the time of such repeal or modification.

     In addition, Article IX of the Company's Bylaws further provides that the
Company shall indemnify its officers, directors and employees to the fullest
extent permitted by law.

     The Company has or will be entering into indemnification agreements with
each of its executive officers and directors.

     These limitations on liability would apply to violations of the federal
securities laws. However, the registrant has been advised that in the opinion of
the SEC, indemnification for liabilities under the Securities Act of 1933 is
against public policy and therefore unenforceable.

ITEM 22. 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
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                                      II-3
<PAGE>   276

     The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (a) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933;

             (b) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;

             (c) To include any material information with respect to the plan of
        distribution not previously disclosed in the registration statement or
        any material change to such information in the registration statement;
        and

             (d) To supply all information concerning a transaction, and the
        company being acquired involved therein, that was not the subject of and
        included in the registration statement when it became effective.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

          (4) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the registrant's annual report
     pursuant to section 13(a) or section 15(d) of the Securities Exchange Act
     of 1934 (and, where applicable, each filing of an employee benefit plan's
     annual report pursuant to section 15(d) of the Securities Exchange Act of
     1934) that is incorporated by reference in the registration statement shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

          (5) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
     Form, within one business day of receipt of such request, and to send the
     incorporated documents by first class main or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of the registration statement through the date of responding
     to the request.

                  (a) The Preferred Stock may be issued from time to time in
         one or more series and in such amounts as may be determined by the
         Board of Directors. The voting powers, designations, preferences and
         relative, participating, optional or other special rights, if any, and

         by the Board of Directors providing for the issue of such series of
         Preferred Stock (herein called the "Directors' Resolution"). The
         Directors' Resolution as to any series shall (1) designate the series,
         (2) fix the dividend rate, if any, of such series, establish whether
         dividends shall be cumulative or non-cumulative, fix the payment dates
         for dividends on shares of such series and the date or dates, or the
         method of determining the date or dates, if any, from which dividends

         the option of the Corporation or at the option of the holder or
         holders of shares of such series or upon the occurrence of a specified
         event, and state whether such shares may be redeemed for cash,
         property or rights, including securities of the Corporation or another
         entity; and such Directors' Resolutions may (i) limit the number of
         shares of such series that may be issued, (ii) provide for a sinking

         series, (iv) impose conditions or restrictions upon the creation of
         indebtedness of the Corporation or upon the issuance of additional

         upon liquidation, (v) impose conditions or restrictions upon the
         payment of dividends upon, or the making of other distributions to, or

         assets upon liquidation, (vi) state the time or times, the price or
         prices or the rate or rates of exchange and other terms, conditions

         the Corporation or upon the occurrence of a specified event, shares of
         any other series of Preferred Stock or any other class or classes of
         stock or other securities of the Corporation, and (vii) grant such
         other special rights and impose such qualifications, limitations or
         restrictions thereon as shall be fixed by the Board of Directors, to
         the extent not inconsistent with this Section 4 and to the full extent
         now or hereafter permitted by the laws of the State of Delaware.

                  Except as by law expressly provided, or except as may be
         provided in any Directors' Resolution, the Preferred Stock shall have

                  Preferred Stock that is redeemed, purchased or retired by the
         Corporation shall assume the status of authorized but unissued
         Preferred Stock and may thereafter, subject to the provisions of any
         Directors' Resolution providing for the issue of any particular series
         of Preferred Stock, be reissued in the same manner as authorized but
         unissued Preferred Stock.

                  (b) Subject to the preferred rights of the holders of shares
         of any series of Preferred Stock as provided by the Board of Directors
         with respect to any such series of Preferred Stock, the holders of the
         Common Stock shall be entitled to receive, as and when declared by the
         Board of Directors out of the funds of the Corporation legally
         available therefor, such dividends (payable in cash, stock or
         otherwise) as the Board of Directors may from time to time determine,
         payable to stockholders of record on such dates, not exceeding 60 days
         preceding the dividend payment dates, as shall be fixed for such
         purpose by the Board of Directors in advance of payment of each
         particular dividend.

                  In the event of any liquidation, dissolution or winding up of
         the Corporation, whether voluntary or involuntary, after the
         distribution or payment to the holders of shares of any series of
         Preferred Stock as provided by the Board of Directors with respect to
         any such series of Preferred Stock, the remaining assets of the
         Corporation available for distribution to stockholders shall be
         distributed among and paid to the holders of Common Stock.

                  Except as otherwise required by law, each holder of shares of
         Common Stock shall be entitled to one vote for each share of Common
         Stock standing in such holder's name on the books of the Corporation
         on all matters submitted to a vote of the stockholders of the
         Corporation (other than the election of one director by the holders of
         the Restricted Common Stock as provided for herein).

                  (c) The holders of the Restricted Common Stock shall not be
         entitled to receive dividends (payable in cash, stock or otherwise).

                  In the event of any liquidation, dissolution or winding up of
         the Corporation, whether voluntarily or involuntarily, after the
         distribution or payment to the holders of shares of any series of
         Preferred Stock as provided by the Board of Directors with respect to
         any such series of Preferred Stock, the remaining assets of the
         Corporation available for distribution to stockholders, if any, shall
         be distributed among and paid to the holders of Common Stock ratably
         in proportion to the number of shares of Common Stock held by them
         respectively. The holders of Restricted Common Stock shall have no
         distribution rights in the event of a liquidation, dissolution or
         winding up of the Corporation.

                  Holders of Restricted Common Stock voting as a class shall be
         entitled to elect one member of the Board of Directors, but shall not
         otherwise be entitled to vote in the election of directors of the
         Corporation. For purposes of electing one member of the Board of
         Directors, each holder of shares of Restricted Common Stock shall be
         entitled to one vote for each share of Restricted Common Stock.
         Subject to the foregoing, and except as otherwise required by law,
         each holder of shares of Restricted Common Stock shall be entitled to
         one-fourth of one vote for each share of Restricted Common Stock
         standing in such holder's name on the books of the Corporation on all
         other matters submitted to a vote of the stockholders of the
         Corporation.

                  (d) If the Restricted Common Stock has not been converted
         into Common Stock pursuant to paragraph (e) below on or prior to the
         third anniversary of April 1, 1999, the Corporation may, at its sole
         option, at any time and from time to time upon prior written notice
         (the "Redemption Notice," such Redemption Notice stating the date on
         which the redemption shall occur (the "Redemption Date")), redeem all
         of the shares of Restricted Common Stock then outstanding. Upon any
         such redemption, the Corporation shall pay, out of funds legally
         available therefor, a price per share of Restricted Common Stock of
         $.01 (the "Redemption Price"). The Corporation shall be obligated on
         the Redemption Date to pay to the holder of each share of Restricted
         Common Stock (upon surrender by such holder at the Corporation's
         principal office of the certificate representing such share) the total
         Redemption Price for the number of shares of Restricted Common Stock
         being redeemed.

                  The Corporation shall mail the Redemption Notice to each
         record holder thereof not more than 90 days nor less than 30 days
         prior to the Redemption Date. The Redemption Notice shall include (i)
         the Redemption Date for such redemption, and (ii) the place where
         share certificates are to be surrendered for payment of the Redemption
         Price. Any shares of Restricted Common Stock which are redeemed or
         otherwise acquired by the Corporation shall be canceled and retired to
         authorized but unissued shares and shall not be reissued, sold or
         transferred.

                  On or prior to April 1, 2002, upon approval of a majority of
         the Corporation's Board of Directors, the Corporation's right to
         redeem the Restricted Common Stock shall be suspended for a period not
         to exceed one year. On or prior to April 1, 2003, upon approval of a
         majority of the Corporation's Board of Directors, the Corporation's
         right to redeem the Restricted Common Stock may be suspended for a
         period not to exceed one year. The Corporation's Board of Directors
         shall not have the ability to suspend the right of the Corporation to
         redeem the Restricted Common Stock beyond April 1, 2004. The
         conversion right set forth below in paragraph (e) shall remain in full
         force and effect during such extension periods and thereafter but
         shall be extinguished on the Redemption Date.

                  (e) Each share of Restricted Common Stock will automatically
         convert into one share of Common Stock (as adjusted proportionately to
         give effect to any stock dividends, combinations, splits or other
         similar events with respect to the Common Stock) in the event the
         Corporation consummates any of the following events: (i) an initial
         public offering of the


                                      -4-

<PAGE>   5



         Corporation's Common Stock, (ii) any sale of all or substantially all
         of the Corporation's assets in one transaction or series of related
         transactions, (iii) any merger or consolidation which involves the
         Corporation in which the Corporation is not the surviving entity, or
         (iv) any transaction after which the shares of the Corporation's
         Common Stock, if any, which are then held by persons other than the
         holders of the Corporation's Common Stock as of the April 1, 1999
         constitute (after giving effect to the exercise of any outstanding
         options or warrants which are convertible into the Corporation's
         Common Stock or the conversion of any of the Corporation's securities
         (equity, debt or otherwise) which are by their terms convertible into
         the Corporation's Common Stock) 50% or more of the Corporation's
         Common Stock outstanding as of the date of the consummation of such
         transaction.

                  (f) The Corporation shall be entitled to treat the person in
         whose name any share of its stock is registered as the owner thereof
         for all purposes and shall not be bound to recognize any equitable or
         other claim to, or interest in, such share on the part of any other
         person, whether or not the Corporation shall have notice thereof,
         except as expressly provided by applicable laws.

         5. The Board of Directors is hereby authorized to create and issue,
whether or not in connection with the issuance and sale of any of its stock or
other securities, rights (the "Rights") entitling the holders thereof to
purchase from the Corporation shares of capital stock or other securities. The
times at which and the terms upon which the Rights are to be issued will 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 shall include, but not be limited to, determination
of the following:

                  (a) The initial purchase price per share of the capital stock
         or other securities of the Corporation to be purchased upon exercise
         of the Rights;

                  (b) Provisions relating to the times at which and the
         circumstances under which the Rights may be exercised or sold or
         otherwise transferred, either together with or separately from, any
         other securities of the Corporation;

                  (c) Provisions that adjust the number or exercise price of
         the Rights or amount or nature of the securities or other property
         receivable upon exercise of the Rights in the event of a combination,
         split or recapitalization of any capital stock of the Corporation, a
         change in ownership of the Corporation's securities or a
         reorganization, merger, consolidation, sale of assets or other
         occurrence relating to the Corporation or any capital stock of the
         Corporation, and provisions restricting the ability of the Corporation
         to enter into any such transaction absent an assumption by the other
         party or parties thereto of the obligations of the Corporation under
         such Rights;



                                      -5-

<PAGE>   6


                  (d) Provisions that deny the holder of a specified percentage
         of the outstanding securities of the Corporation the right to exercise
         the Rights and/or cause the Rights held by such holder to become void;

                  (e) Provisions that permit the Corporation to redeem the
         Rights; and

                  (f) The appointment of a Rights Agent with respect to the
         Rights;

         and such other provisions relating to the Rights as may be determined
by the Board of Directors.

         6. No holder of stock of the Corporation shall be entitled as of right
to purchase or subscribe for any part of any unissued stock of the Corporation
or any additional stock to be issued whether or not by reason of any increase
of the authorized capital stock of the Corporation, or any bonds, certificates
of indebtedness, debentures or other securities convertible into stock or such
additional authorized issuance of new stock, but rather such stock, bonds,
certificates of indebtedness, debentures and other securities may be issued and
disposed of pursuant to resolution of the Board of Directors to such persons,
firms, corporations or associations, and upon such terms as may be deemed
advisable by the Board of Directors in the exercise of their discretion.

         7. The following provisions are inserted for the management of the
business and for the conduct of the affairs of the Corporation, and for
creating, defining, limiting and regulating the powers of the Corporation, the
directors and the stockholders.

                  (a) Subject to any limitation contained in the bylaws, the
         Board of Directors may make bylaws, and from time to time may alter,
         amend or repeal any bylaws, but any bylaws made by the Board of
         Directors may be altered, amended or repealed by the stockholders at
         any meeting of stockholders by the affirmative vote of at least 66
         2/3% of the aggregate number of votes entitled to be cast thereon,
         provided notice that an amendment is to be considered and acted upon
         is inserted in the notice or waiver of notice of such meeting.

                  (b) Any vote or votes authorizing liquidation of the
         Corporation or proceedings for its dissolution may provide, subject to
         (i) any agreements among and between stockholders, (ii) the rights of
         creditors and (iii) rights expressly provided for particular classes
         or series of stocks, for the distribution pro rata among the
         stockholders of the Corporation of the assets of the Corporation,
         wholly or in part in kind, whether such assets be in cash or other
         property, and may authorize the Board of Directors of the Corporation
         to determine the value of the different assets of the Corporation for
         the purpose of such liquidation and may divide such assets or any part
         thereof among the stockholders of the Corporation in such manner that
         every stockholder will receive a proportionate amount in value
         (determined as aforesaid) of cash or property of the Corporation upon
         such liquidation or dissolution even though each stockholder may not
         receive a strictly proportionate part of each such asset.

                  (c) The Corporation shall, to the maximum extent permitted
         from time to time under the DGCL, indemnify and upon request shall
         advance expenses to any person who is or was a party or is threatened
         to be made a party to any threatened, pending or completed action,
         suit, proceeding or claim, whether civil, criminal, administrative or
         investigative, by reason of the fact that he is or was or has agreed
         to be a director or officer of the Corporation, or while a director or
         officer 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, including
         service with respect to employee benefit plans, against expenses
         (including attorneys' fees and expenses), judgments, fines, penalties
         and amounts paid in settlement or incurred in connection with the
         investigation, preparation to defend or defense of such action, suit,
         proceeding, claim or counterclaim initiated by or on behalf of such
         person. Such indemnification shall not be exclusive of other
         indemnification rights arising under any bylaw, agreement, vote of
         directors or stockholders or otherwise and shall inure to the benefit
         of the heirs and legal representatives of such person. Any repeal or
         modification of this Section 7(c) shall be prospective only, and shall
         not adversely affect any right or protection of a director or officer
         of the Corporation existing at the time of such repeal or
         modification.

                  (d) A director of the Corporation shall not be personally
         liable to the Corporation or its stockholders for monetary damages for
         breach of fiduciary duty as a director, except for liability (i) for
         any breach of the director's duty of loyalty to the Corporation or its
         stockholders, (ii) for acts or omissions not in good faith or which
         involve intentional misconduct or a knowing violation of law, (iii)
         under Section 174 of the DGCL, or (iv) for any transaction from which
         the director derived an improper personal benefit. 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. Any repeal or
         modification of this Section 7(d) by the stockholders of the
         Corporation shall be prospective only, and shall not adversely affect
         any limitation on the personal liability of a director of the
         Corporation existing at the time of such repeal or modification.

         8. Subject to the rights of the holders of any class or series of
stock having a preference over the Common Stock as to dividends or upon
liquidation to elect additional directors under specific circumstances:

                  (a) after an initial public offering of the Corporation's
         Common Stock, any action required or permitted to be taken by the
         stockholders of the Corporation must be effected at a duly called
         annual or special meeting of stockholders of the Corporation and may
         not be effected by any consent in writing of such stockholders;

                  (b) special meetings of the stockholders of the Corporation
         may be called only by the Chairman of the Board of Directors and shall
         be called within ten (10) days after receipt of the written request of
         the Board of Directors, pursuant to a resolution approved by a
         majority of the whole Board of Directors; and



                                      -7-

<PAGE>   8


                  (c) the business permitted to be conducted at any special
         meeting of the stockholders is limited to the business brought before
         the meeting by the Chairman or by the Secretary at the request of a
         majority of the Board of Directors.

         9. The number of directors which shall constitute the whole board
shall be such as from time to time shall be fixed by, or in the manner provided
in, the bylaws, but in no case shall the number be less than three nor more
than 15.

         The directors shall be classified with respect to the time for which
they shall severally hold office by dividing them into three classes which
classes shall consist of an equal, or as near to equal as possible, number of
directors. As to the initial election, the director or directors of the first
class shall be elected for a term expiring at the next annual meeting of
stockholders to be held following the end of the 2000 fiscal year; the director
or directors of the second class for a term expiring at the annual meeting to
be held following the end of the 2001 fiscal year; and the director or
directors of the third class for a term expiring at the annual meeting to be
held following the end of the 2002 fiscal year. At each annual meeting,
commencing with the annual meeting in 2001, the successor or successors to the
class of directors whose term shall expire in that year shall be elected to
hold office for a term of three years, so that the term of office of one class
of directors shall expire in each year. Any increase or decrease in the number
of directors constituting the Board shall be apportioned among the classes so
as to maintain the number of directors in each class as near as possible to
one-third the whole number of directors as so adjusted. Any director elected or
appointed to fill a vacancy shall hold office for the remaining term of the
class to which such directorship is assigned. No decrease in the number of
directors constituting the Corporation's Board of Directors shall shorten the
term of any incumbent director. Any vacancy in the Board of Directors, whether
arising through death, resignation or removal of a director, or through an
increase in the number of directors of any class, shall be filled by the
majority vote of the remaining directors, although less than a quorum, or by a
sole remaining director, provided that any vacancy in the Board of Directors
arising through death, resignation or removal of the director elected by the
Restricted Common Stock shall be filled only by a special meeting of the
holders of the Restricted Common Stock called for the purpose of electing a
director to fill such vacancy. The bylaws may contain any provision regarding
classification of the Corporation's directors not inconsistent with the terms
hereof. The right to cumulate votes in the election of directors is expressly
prohibited.

         A director of the Corporation may be removed only for cause and only
upon the affirmative vote of the holders of 66 2/3 percent of the outstanding
capital stock of the Corporation entitled to vote at an election of such
director, subject to further restrictions on removal, not inconsistent with
this Section 9, as may be contained in the bylaws. Notwithstanding the
foregoing, the holders of Restricted Common Stock voting as a class shall be
entitled to elect one member of the Board of Directors, and only the holders of
the Restricted Common Stock shall be entitled to remove such member from the
Board of Directors.


                                      -8-

<PAGE>   9


         Notwithstanding the foregoing, whenever the holders of any one or more
series of Preferred Stock issued by the Corporation shall have the right,
voting separately by series, to elect directors at an annual or special meeting
of stockholders, the election, term of office, filling of vacancies and other
features of such directorships shall be governed by the terms of the Directors'
Resolutions applicable thereto, and such directors so elected shall not be
subject to the provisions of this Section 9 unless expressly provided by such
terms.

         10. Election of directors need not be by written ballot unless the
bylaws of the Corporation shall so provide. Meetings of stockholders may be
held within or without the State of Delaware, as the bylaws may provide. The
books of the Corporation may be kept (subject to any provisions contained in
the statutes of the State of Delaware) outside the State of Delaware at such
place or places as may be designated from time to time by the Board of
Directors or the bylaws of the Corporation.

         11. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Amended and Restated Certificate of
Incorporation in the manner set forth below, and all rights and conferred upon
the directors or stockholders of the Corporation herein or in any amendment
hereof are granted subject to this reservation.

         The affirmative vote of at least 75% of the aggregate number of votes
entitled to be cast thereon and the affirmative vote of the holders of at least
75% of the then outstanding shares of each class of stock of the Corporation
voting separately as a class, shall be required to adopt any amendment to
Sections 5, 7, 8, 9 and 11 of this Amended and Restated Certificate of
Incorporation of the Corporation, provided that holders of shares of any series
of Preferred Stock shall not be entitled to vote with respect to any such
amendment unless (i) specifically required by the Directors' Resolution
providing for the issue of such series of Preferred Stock or (ii) otherwise
required by the DGCL.

         The affirmative vote of at least a majority of the aggregate number of
votes entitled to be cast thereon and the affirmative vote of the holders of at
least a majority of the then outstanding shares of each class of stock of the
Corporation voting separately as a class, shall be required to adopt any
amendment to any other Section of this Amended and Restated Certificate of
Incorporation of the Corporation, provided that holders of shares of any series
of Preferred Stock shall not be entitled to vote with respect to any such
amendment unless (i) specifically required by the Directors' Resolution
providing for the issue of such series of Preferred Stock or (ii) otherwise
required by the DGCL.

         IN WITNESS WHEREOF, this Amended and Restated Certificate of
Incorporation has been executed for and on behalf of the Corporation by its
officers thereunto duly authorized as of ______ day of March, 1999.

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

         Section 1. All meetings of the stockholders for the election of
Directors shall be held at such place as may be fixed from time to time by the
Board of Directors and stated in the notice of the meeting. Meetings of
stockholders for any other purpose may be held at such time and place, within or
without the State of Delaware, as shall be stated in the notice of the meeting
or in a duly executed waiver of notice thereof.

         Section 2. Annual meetings of stockholders shall be held on such date
and at such time as shall be designated from time to time by the Board of
Directors and stated in the notice of the meeting. At the annual meeting, the
stockholders shall elect by a plurality vote the Directors pursuant to Article
III of these Bylaws, and transact such other business as may properly be brought
before the meeting.

         Section 3. Written notice of the annual meeting stating the place, date
and hour of the meeting shall be given to each stockholder entitled to a vote at
such meeting not less than ten (10) nor more than sixty (60) days before the
date of the meeting.

         At an annual meeting of the stockholders, only such business shall be
conducted as shall have been properly brought before the meeting. To be properly
brought before an annual meeting, business must be (i) specified in the notice
of meeting (or any supplement thereto) given by or at the direction of the Board
of Directors, (ii) otherwise properly brought before the meeting by or at the
direction of the Board of Directors, or (iii) otherwise properly brought before
the meeting by a stockholder. For business to be properly brought before an
annual meeting by a stockholder, the stockholder must have given timely notice
thereof in writing to the Secretary of the Corporation. To be timely, a
stockholder's notice must be delivered to or mailed to and received at the
principal executive offices of the Corporation not less than 120 days nor more
than 150 days prior to the anniversary of the date of the proxy statement for
the previous year's annual meeting; provided, however, that if no annual meeting

time of the previous year's proxy statement, the notice must be received by the
Corporation at least 60 days prior to the date the Corporation intends to

         A stockholder's notice to the Secretary shall set forth, as to each
matter a stockholder proposes to bring before the annual meeting, (i) the nature
of the proposed business with reasonable particularity, including the exact text
of any proposal to be presented for adoption and any supporting statement, which
proposal and supporting statement shall not in the aggregate exceed 500 words,
and his reasons for conducting such business at the annual meeting, (ii) any
material interest of such stockholder in such business, (iii) the name,
principal occupation and record address of such stockholder, (iv) the class and
number of shares of the Corporation which are held of record or beneficially
owned by such stockholder, (v) the dates upon which such stockholder acquired
such shares of stock and documentary support for any claims of beneficial
ownership and (vi) such other matters as may be required by the Certificate of
Incorporation as amended or restated from time to time (the "Certificate of
Incorporation").

         Notwithstanding any other provision in these Bylaws, no business shall
be conducted at an annual meeting except in accordance with the procedures set
forth in this Section 3. The presiding officer of an annual meeting shall, if
the facts warrant, determine and declare to the meeting that business was not
properly brought before the meeting in accordance with this Section 3, and if
the presiding officer should so determine, the presiding officer shall so
declare to the meeting and any such business not properly brought before the
meeting shall not be transacted.

         At any special meeting of stockholders, only such business shall be
conducted as shall have been specified in the notice of meeting (or any
supplement thereto) given by or at the direction of the Board of Directors. In
accordance with Section 5 of this Article II, nothing in this Section 3 shall
entitle any stockholder to propose business for consideration at any special
meeting of stockholders.

         Notwithstanding any other provision of these Bylaws, the Corporation
shall be under no obligation to include any stockholder proposal in its proxy
statement or otherwise present any such proposal to stockholders at a meeting of
stockholders if the Board of Directors reasonably believes that the proponents
thereof have not complied with Sections 13 and 14 of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), and the rules and regulations
promulgated thereunder; and the Corporation shall not be required to include in
its proxy statement to stockholders any stockholder proposal not required to be
included in its proxy statement to stockholders in accordance with the Exchange
Act and such rules or regulations; provided, however, nothing in this Section 3
shall be deemed to affect the rights of stockholders to request inclusion of
proposals in the Corporation's proxy statement pursuant to Rule 14a-8 under the
Exchange Act.

         Section 4. The officer who has charge of the stock ledger of the
Corporation shall prepare and make, at least ten (10) days before every meeting
of stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list

                                       -2-

<PAGE>   4




shall be open to the examination of any stockholder, for any purpose germane to
the meeting, during ordinary business hours, for a period of at least ten (10)
days prior to the meeting, either at a place within the city where the meeting
is to be held, which place shall be specified in the notice of the meeting, or,
if not so specified, at the place where the meeting is to be held. The list
shall also be produced and kept at the time and place of the meeting during the
whole time thereof, and may be inspected by any stockholder who is present.

         Section 5. Special meetings of the stockholders for any purpose may be
called only by the Chairman of the Board of Directors and shall be called within
10 days after receipt of the written request of the Board of Directors, pursuant

business permitted to be conducted at any special meeting of the stockholders is
limited to the business brought before the meeting by the Chairman or by the
Secretary at the request of a majority of the entire Board of Directors.

         Section 6. Written notice of a special meeting stating the place, date
and hour of the meeting, and the purpose or purposes for which the meeting is
called, shall be given not less than ten (10) nor more than sixty (60) days
before the date of the meeting, to each stockholder entitled to vote at such
meeting.

         Section 7. The holders of a majority of the stock issued, outstanding
and entitled to vote, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the Certificate of
Incorporation. If, however, such quorum shall not be present or represented at
any meeting of the stockholders, the stockholders entitled to vote thereat,
present in person or represented by proxy, shall have power to adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present or represented.

         Section 8. When a meeting is adjourned to another time or place, notice
need not be given of the adjourned meeting, except as otherwise required by this
Section 8, if the time and place thereof are announced at the meeting at which
the adjournment is taken. At such adjourned meeting the Corporation may transact
any business which might have been transacted at the original meeting. If the
adjournment is for more than thirty (30) days, or if after the adjournment a new
record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting.

         Section 9. If a quorum exists, action on a matter (other than the
election of directors) shall be approved if the votes cast in favor of the
matter exceed the votes cast opposing the matter. In determining the number of
votes cast, shares abstaining from voting or not voted on a matter will not be
treated as votes cast. The provisions of this paragraph will govern with respect
to all votes of stockholders except as otherwise provided for in these Bylaws or
in the Certificate of Incorporation or by a specific statutory provision
superseding the provisions contained in these Bylaws or the Certificate of
Incorporation.

         Section 10. Each stockholder shall at every meeting of the
stockholders, subject to any restriction or qualification set forth in the
Certificate of Incorporation, be entitled to one vote in person or by proxy for
each share of the capital stock having voting power held by such stockholder,
but no proxy shall be voted after three years from its date, unless the proxy
provides for a longer period.

         Section 11. After an initial public offering of the Corporation's
Common Stock, any action required or permitted to be taken by the stockholders
of the Corporation must be affected at a duly called annual or special meeting
of stockholders of the Corporation and may not be effected by any consent in
writing of such stockholders.

         Section 12. At each meeting of stockholders, the Chairman or
Vice-Chairman of the Board of Directors shall preside, and the secretary shall
keep records, and in the absence of either such officer, his duty shall be
performed by a person appointed at the meeting.

                                   ARTICLE III

Director may be removed for cause by the affirmative vote of the holders of at
least 662/3 percent of the capital stock of the Corporation entitled to vote at

                                    EXHIBIT A


       Section 1. Number of Shares and Designation. This series of preferred
stock shall be designated as "10% Cumulative Redeemable Convertible Preferred
Stock, Series A" and the number of shares which shall constitute such series
shall not be more than 1,048,820 shares, par value $.01 per share. For the
purpose of this Certificate of Designations, the 10% Cumulative Redeemable
Convertible Preferred Stock, Series A, shall be referred to as the "Series A
Preferred."

       Section 2. Dividends.

       (a) General Obligation. When, as and if declared by the Board of
Directors and to the extent permitted under the Delaware law, the Corporation
shall pay preferential dividends in cash to the holders of the Series A
Preferred as provided in this Section 2. Dividends on each share of the Series A
Preferred shall accrue on a daily basis at the rate of 10% per annum of the sum
of the Liquidation Value (as defined in Section 3(f) hereof) thereof plus all
accumulated and unpaid dividends thereon from and including the date of issuance
of such share to and including the first to occur of (i) the date on which the
Liquidation Value of such share (plus all accrued and unpaid dividends thereon)
is due and payable to the holder thereof in connection with the liquidation of
the Corporation or the redemption of such share by the Corporation, (ii) the
date on which such share is converted into shares of Common Stock as provided
hereunder or (iii) the fortieth (40th) day immediately following the IPO
Prospectus Delivery Termination Date (as defined in Section 6(a) hereof.)
Dividends shall accrue whether or not they have been declared and whether or not
there are profits, surplus or other funds of the Corporation legally available
for the payment of dividends.

       (b) Dividend Payment Dates. All dividends which have accrued on the
Series A Preferred shall be payable on June 30 and December 31 of each year,
beginning June 30,1999 (the "Dividend Payment Dates"). All dividends which have
accrued on each share of Series A Preferred outstanding during the six-month
period (or other period in the case of an initial Dividend Payment Date) ending
upon such Dividend Payment Date shall be accumulated and shall remain
accumulated dividends with respect to such shares until paid to the holder
thereof. If a Dividend Payment Date falls on any date other than a business day,
the dividend payment due on such Dividend Payment Date shall be paid on the
business day immediately following such Dividend Payment Date, with the same
effect as if paid on the Dividend Payment Date without any additional accrual of
dividends payable in respect of such delay. Dividends payable on each Dividend
Payment Date shall be paid to record holders of the shares of Series A Preferred
as they appear on the books of the Corporation at the close of business on a
date (the "Dividend Record Date") fixed by the Board of Directors not more than
60 nor less than 30 days immediately preceding the applicable Dividend Payment
Date.

       (c) Distribution of Partial Dividend Payments. Except as otherwise
provided herein, if at any time the Corporation pays less than the total amount
of dividends then accrued with respect to the Series A Preferred, such payment
shall be distributed pro rata among the holders thereof based upon the aggregate
accrued but unpaid dividends on the shares of Series A Preferred held by each
such holder.



                                       -4-

<PAGE>   5



       (d) Participation in Dividends with Common Stock. The Series A Preferred
shall be entitled to receive dividends, in addition to the dividends otherwise
payable pursuant to paragraph (a) above, on the same basis and in the same
amount as any dividend declared and paid on the Common Stock, on a per share
basis, (i) when, as and if declared by the Board of Directors, (ii) to the
extent permitted by Delaware law and (iii) if, after taking into account all
dividends declared and paid on the Common Stock from and after the first date of
issuance of the Series A Preferred, the Corporation has paid to the holders of
Common Stock cumulative dividends equal to the amount determined by applying,
for each share of Common Stock outstanding at the time such determination is
made, the rate of 10% per annum of the Common Stock Base Amount (as defined
below) for the period commencing from (x) with respect to each share of Common
Stock outstanding on the date of the first issuance of shares of Series A
Preferred, the date of the first issuance of shares of Series A Preferred and
(y) with respect to each share of Common Stock issued thereafter, the date of
such issuance. The "Common Stock Base Amount", as of any particular date, shall
be equal to $13.00 per share (as adjusted proportionately for any stock
dividends, combinations, splits or other similar events with respect to such
shares).

       (e) The holders of shares of Series A Preferred shall not be entitled to
receive any dividends or other distributions except as provided herein.

       Section 3. Liquidation.

       (a) Upon any liquidation, dissolution or winding up of the Corporation,
whether voluntary or involuntary (a "Liquidation"), each holder of Series A
Preferred shall be entitled to receive, out of the assets of the Corporation
available for distribution to stockholders, after any distribution of payment is
made upon any securities of the Corporation senior in ranking to the Series A
Preferred (the "Senior Securities"), and before any distribution or payment is
made upon any securities of the Corporation junior in ranking to the Series A
Preferred (the "Junior Securities"), an amount in cash equal to the aggregate
Liquidation Value of all shares of Series A Preferred held by such holder (plus
all accrued and unpaid dividends thereon through the effective date of the
Liquidation). If, upon any Liquidation and after payment or distribution is made
upon any Senior Securities, the Corporation's assets to be distributed among the
holders of the Series A Preferred are insufficient to permit payment to such
holders of the Series A Preferred of the aggregate amount which they are
entitled to be paid under this Section 3(a), then the entire assets available to
be distributed to the holders of the Series A Preferred shall be distributed pro
rata among such holders based upon the aggregate Liquidation Value (plus all
accrued and unpaid dividends thereon through the effective date of the
Liquidation) of the Series A Preferred held by each such holder.

       (b) After the payment or distribution to the holders of Series A
Preferred in full of the preferential amount provided in Section 3(a), the
holders of Common Stock shall be entitled to receive ratably an amount per share
equal to the Common Stock Base Amount plus an amount equal to the cumulative
dividend amount with respect to such share computed in accordance with clause
(iii) of Section 2(d) hereof. If, upon any Liquidation and after payment or
distribution in full of the preferential amount specified in Section 3(a), the
Corporation's assets to be distributed among the holders of the Common Stock are
insufficient to permit payment to such holders of the Common


                                       -5-




<PAGE>   6



Stock of the aggregate amount to which they are entitled to be paid under this
Section 3(b), then the entire remaining assets available to be distributed
shall be distributed pro rata among the holders of Common Stock.

       (c) After the payment or distribution to the holders of the Series A
Preferred and the holders of the Common Stock as provided in Section 3(a) and
Section 3(b), the holders of Series A Preferred and the holders of the Common
Stock shall be entitled to receive ratably, on a per share basis, all remaining
assets of the Corporation to be paid or distributed.

       (d) Prior to a Liquidation, the Series A Preferred shall be convertible
into Common Stock only in accordance with the provisions of Section 6 below.

       (e) Neither the consolidation or merger of the Corporation into or with
any other entity or entities (whether or not the Corporation is the surviving
entity), or the sale, conveyance, exchange or transfer (for cash, securities or
other consideration) by the Corporation of all or any part of its assets, or the
reduction of the capital stock of the Corporation nor any other form of
recapitalization or reorganization affecting the Corporation shall be deemed to
be a Liquidation within the meaning of this Section 3.

       (f) The "Liquidation Value" of any share of Series A Preferred, as of any
particular date, shall be equal to $13.00 (as adjusted proportionately for any
stock dividends, combinations, splits or other similar events with respect to
such shares).

       Section 4. Redemptions.

       (a) Redemption at the Option of the Holders.

              (i) Effective upon the occurrence of the third anniversary of the
issuance of the shares of Series A Preferred, each holder of such shares shall
have the right (a "Put Right"), but not the obligation, to require the
Corporation to purchase the shares of Series A Preferred then owned by such
holder. The purchase price for such redemption, which shall be paid out of funds
legally available therefor, shall be the Liquidation Value of such shares plus
all accrued and unpaid dividends thereon to the date of redemption (the
"Redemption Date").

              (ii) The holders may exercise their Put Right by giving written
notice (a "Put Notice") to the Corporation. Upon receipt of a Put Notice, the
Corporation shall promptly mail a Redemption Notice (as defined below) to the
holders exercising their Put Right which includes the information set forth in
Section 4(c) hereof. The Redemption Date with respect to the shares of Series A
Preferred to be redeemed upon exercise of a Put Right shall in no event be later
than 90 days after the date the Corporation first receives the Put Notice.



                                       -6-


<PAGE>   7



       (b) Redemption at the Option of the Corporation.

              (i) The Corporation may, in its sole discretion, at any time and
from time to time upon prior written notice redeem all or any portion of shares
of Series A Preferred then outstanding. The purchase price for each share of
Series A Preferred to be redeemed pursuant to this Section 4(b), which shall be
paid out of funds legally available therefor, shall be the greater of (i) the
Liquidation Value of a share of Series A Preferred and (ii) the Fair Market
Value (as defined below) of a share of Series A Preferred as of the Redemption
Record Date (as defined below) plus, in the case of each of clauses (i) and
(ii), all accrued and unpaid dividends thereon to the Redemption Date. The
Corporation shall mail a Redemption Notice which includes the information set
forth in Section 4(c) hereof for each redemption to each holder of record
thereof as of a date (the "Redemption Record Date") not more than 90 days nor
less than 30 days prior to the Redemption Date.

              (ii) For the purpose of any computation under clause (i) above,
the "Fair Market Value" of a share of Series A Preferred on any date shall be
deemed to be, if the Common Stock is then listed or admitted for trading on the
New York Stock Exchange ("NYSE"), the National Association of Securities Dealers
Automated Quotation National Market ("NASDAQ"), or any over-the -counter market,
the average of the daily Closing Prices for the Common Stock for the thirty (30)
consecutive business days commencing forty-five (45) business days before such
date or, if the Common Stock is not then listed or admitted for trading on the
NYSE, NASDAQ or any over-the-counter market, the fair market value thereof as
determined in good faith by the Corporation's Board of Directors. Where used
herein, the "Closing Price" for each day shall be the reported last sale price
regular way or in the case no such reported sale takes place on such day, the
average of the reported closing bid and asked prices regular way, in either case
as reported on the New York Stock Exchange Composite Transactions reporting
system or, if not so quoted, on the NYSE or, if at any time the Common Stock is
not listed or admitted to trading on the NYSE, on the principal national
securities exchange on which the Common Stock is listed or admitted to trading,
or if the Common Stock is not listed or admitted to trading on any national
securities exchange, on the NASDAQ, or, if the Common Stock is not listed or
admitted to trading on any national securities exchange or quoted on NASDAQ, the
average of the closing bid and asked prices in the over-the-counter market as
furnished by any NYSE member firm selected from time to time by the Board of
Directors for such purposes.

              (iii) In the event the Corporation elects to redeem less than the
total number of shares of Series A Preferred outstanding as of the Redemption
Record Date, the number of shares of Series A Preferred to be redeemed from each
holder thereof in redemptions pursuant to this Section 4(b) shall be the number
of shares determined by multiplying (A) the total number of shares to be
redeemed by the Corporation times (B) a fraction, the numerator of which shall
be the total amount of Liquidation Value (plus aggregate accrued and unpaid
dividends) represented by the shares held by such holder as of the Redemption
Record Date, and the denominator of which shall be the total amount of
Liquidation Value (plus aggregate accrued and unpaid dividends) represented by
the all of the shares outstanding as of the Redemption Record Date.

       (c) Redemption Notice. The "Redemption Notice" sent to holders of shares
of Series A Preferred pursuant to Section 4(a)(ii) or Section 4(b)(i) hereof
shall set forth (A) the Redemption


                                       -7-


<PAGE>   8



Date for such redemption, (B) the total number of shares of Series A Preferred
to be redeemed and (C) if fewer than all of the shares held by such holder are
to be redeemed, the number of shares to be redeemed from such holder, (D) the
purchase price for shares to be redeemed and (E) the place and time of day
where share certificates are to be surrendered for payment of the redemption
price. Upon mailing any Redemption Notice which relates to redemption at the
option of the Corporation pursuant to Section 4(b) hereof, the Corporation
shall become obligated to redeem the total number of shares specified in such
notice on the Redemption Date specified therein.

       (d) Closing on the Redemption Date. Any closing of the sale of shares of
Series A Preferred redeemed pursuant this Section 4 shall take place on the
Redemption Date specified in the Redemption Notice at the time and place
specified therein, unless mutually agreed to in writing by the Corporation and
the redeeming holder. At such closing the Corporation shall make payment for the
shares of Series A Preferred to be repurchased by wire transfer of immediately
available funds to a bank account designated by such holder for such purpose and
such holder shall deliver to the Corporation certificates, duly endorsed for
transfer, representing the shares of Series A Preferred to be redeemed. In the
case where fewer than the total number of shares represented by any certificate
are redeemed, upon surrender at the closing of the certificate representing the
redeemed shares, a new certificate representing the number of unredeemed shares
of Series A Preferred shall be issued to the holder thereof without cost to the
holder on the Redemption Date.

       (e) No Dividends after Redemption Date. No shares of Series A Preferred
to be redeemed shall be entitled to any dividends accruing after the Redemption
Date with respect to such shares. On such date, all rights attributable to such
shares shall cease and such shares shall no longer be deemed to be issued and
outstanding.

       Section 5. Voting Rights. (a) Except as set forth below or as otherwise
provided by Delaware law, holders of shares of Series A Preferred shall not be
entitled to vote as a separate class, but shall vote together with the holders
of shares of all other classes of capital stock of the Corporation having
general voting powers as one class, on all matters submitted to a vote of the
Corporation's stockholders. Each holder of shares of Series A Preferred shall
be entitled to the number of votes equal to the number of full shares of Common
Stock into which all shares of Series A Preferred Stock held by such holder
would be converted pursuant to the provisions of Section 6(a)(i) hereof (as
adjusted proportionately for any stock dividends, combinations, splits or other
similar events with respect to such shares), at the record date for the
determination of the stockholders entitled to vote on such matters or, if no
such record date is established, at the date such vote is taken or any written
consent of stockholders is first executed (assuming, for purposes of
determining the number of votes if such shares of Series A Preferred were
converted pursuant to Section 6, a price to the public of a share of Common
Stock in an IPO (as defined in Section 6(a) hereof) of $13.00 per share). In
all cases where the holders of shares of Series A Preferred have the right to
vote separately as a class as provided elsewhere herein or otherwise by
Delaware law, such holders shall be entitled to one vote for each such share
held by them respectively.

       (b) Without the affirmative vote of the holders of not less than a
majority of the shares of Series A Preferred, voting together as a single
class, the Corporation shall not:


                                       -8-


<PAGE>   9



              (i) authorize the issuance of any new class or series of stock or
reclassify any existing stock into stock having rights and preferences on parity
with or prior and superior to the Series A Preferred as to dividends or amounts
payable upon liquidation or dissolution;

              (ii) increase or decrease the total number of authorized shares of
Series A Preferred;

              (iii) purchase, redeem or otherwise acquire for value (or pay into
or set aside as a sinking fund for such purpose) any of the Common Stock;
provided, that this provision shall not apply to the repurchase of shares of
Common Stock under the terms of the Acquisition Agreements; or

              (iv) make any amendment to the Certificate of Incorporation of the
Corporation that would adversely change the rights, preferences, privileges or
restrictions of or on the holders of the Series A Preferred set forth in this
Certificate of Designations.


       (c) At any time and for so long as either (i) the Corporation has failed
to punctually pay when due any redemption payment pursuant to Section 4 hereof
or (ii) dividends payable on the Series A Preferred pursuant to Section 2 hereof
have been in arrears and unpaid for a period of forty days following the
applicable Dividend Payment Date, the Corporation shall not, without the
affirmative vote of the holders of not less than a majority of the shares of
Series A Preferred, voting together as a single class:

              (i) incur any additional indebtedness for borrowed money other
than borrowings under any credit facility to which the Corporation is a party at
such time and as in effect when any redemption payment becomes due and is unpaid
or at the time any Dividend Payment becomes due and is unpaid;

              (ii) effect (or make any agreement or become obligated to effect)
any (a) sale, lease, assignment, transfer or other conveyance of the assets of
the Corporation or its Subsidiaries which individually or in the aggregate would
constitute a Significant Subsidiary, (b) consolidation or merger involving the
Corporation or any of its Subsidiaries, or (c) dissolution, liquidation or
winding-up of the Corporation or any of its Subsidiaries; provided however that
in no event shall the Corporation effect any sale, lease, assignment, transfer
or other conveyance of the assets of the Corporation or its Subsidiaries to
Affiliates of the Corporation;

              (iii) make (or permit any Subsidiary to make) any loan or advance
to, or own any stock or other securities of, any Subsidiary or other
corporation, partnership, or other entity unless it is wholly owned by the
Corporation and except for any such loans and advances which do not in the
aggregate exceed $250,000;

              (iv) make any loan or advance to any person, including, without
limitation, any employee or director of the Corporation or any Subsidiary,
except advances and similar expenditures in the ordinary course of business; or


                                       -9-


<PAGE>   10



              (v) acquire, by purchase, exchange, merger or otherwise, all of
substantially all of the properties or assets of any other corporation or

means a Subsidiary of the Corporation.

       "Voting Stock" with respect to any Person, means securities of any class

       Section 6. Conversion.

       (a) Conversion at Election of Corporation

              (i) Upon and at any time and from time to time after the
consummation of a firm commitment underwritten initial public offering of the
Common Stock managed by one or more nationally recognized national investment
banking firms which is registered under the Securities Act of 1933 (an "IPO"),
the Corporation may convert all or any portion of the issued and outstanding
shares of Series A Preferred at a conversion ratio of one share of Common Stock
for each share of Series A Preferred to be converted (the "Equivalent Basis
Conversion Ratio"), provided, however, that if the Equivalent Basis Conversion
Ratio results in a lesser number of shares of Common Stock upon conversion of a
share of Series A Preferred than the Floating Conversion Ratio (as defined in


                                      -10-


<PAGE>   11



Section 6(c) hereof), then the conversion of the Series A Preferred pursuant to
this Section 6(a) shall be made utilizing the Floating Conversion Ratio.

              (ii) In the event that the Corporation elects to convert shares of
Series A Preferred, the Corporation shall mail a Conversion Notice (as defined
below) which includes the information set forth in paragraph 6(b) hereof for
each conversion to each holder of record thereof as of a date (the "Conversion
Record Date") not more than 90 days nor less than 30 days prior to the date of
conversion specified in the Conversion Notice (the "Corporation-Elected
Conversion Date"). In the event the Corporation elects to convert less than the
total number of shares of Series A Preferred outstanding as of the Conversion
Record Date, the number of shares of Series A Preferred of each holder to be
converted pursuant to this Section 6(a) shall be the number of shares of Series
A Preferred determined by multiplying the total number of shares of Series A
Preferred to be converted by the Corporation times a fraction, the numerator of
which shall be the total amount of Liquidation Value (plus aggregate accrued and
unpaid dividends) represented by the shares held by such holder as of the
Conversion Record Date, and the denominator of which shall be the total amount
of Liquidation Value (plus aggregate accrued and unpaid dividends), determined
as of the applicable Conversion Date, represented by all of the shares
outstanding as of the Conversion Record Date.

              (iii) The "Conversion Notice" sent to holders of shares of Series
A Preferred pursuant to Section 6(a)(ii) hereof shall set forth (A) the
Corporation-Elected Conversion Date for such conversion, (B) the total number of
shares of Series A Preferred to be converted, (C) the number of shares of Series
A Preferred held by such holder, (D) the conversion ratio applicable to such
conversion and (E) the time of day and place where Series A Preferred share
certificates are to be surrendered on the Corporation-Elected Conversion Date in
exchange for certificates representing shares of Common Stock. Upon mailing any
Conversion Notice which relates to conversion at the option of the Corporation,
the Corporation shall become obligated to convert the total number of shares of
Series A Preferred specified in such notice into shares of Common Stock on the
Corporation-Elected Conversion Date specified therein.

              (iv) The holders of Series A Preferred shall surrender
certificates representing the number of shares of Series A Preferred specified
in the Conversion Notice at the time and place specified therein on the
Corporation-Elected Conversion Date, duly endorsed for transfer.

       (b) Conversion at Election of Holder.

              (i) At any time and from time to time prior to the filing by the
Corporation of a registration statement with the Securities and Exchange
Commission (the "SEC") relating to a proposed IPO (the "IPO Registration
Statement"), a holder of Series A Preferred may convert all or any portion of
the issued and outstanding shares of Series A Preferred owned by such holder at
the Equivalent Basis Conversion Ratio. In the event that the Corporation
determines to file an IPO Registration Statement, the Corporation shall give
written notice to each holder of Series A Preferred not less than 30 days prior
to filing the IPO Registration Statement with the SEC.



                                      -11-


<PAGE>   12



              (ii) Each conversion of shares of Series A Preferred pursuant to
Section 6(b) shall be deemed to have been effected as of the close of business
on the date on which the certificate or certificates representing the shares of
such Series A Preferred to be converted, together with properly executed
conversion instructions or powers, have been surrendered for conversion at the
principal office of the Corporation (the "Holder-Elected Conversion Date").

              (iii) Notwithstanding anything to the contrary in this Section
6(b), from and after the receipt by a holder of Series A Preferred of a
Redemption Notice from the Corporation pursuant to Section 4(b) through 5:00
p.m. New York time on the business day immediately preceding the Redemption Date
related thereto, a holder of Series A Preferred may convert all or a portion of
the issued and outstanding shares of Series A Preferred owned by such holder at
the Equivalent Basis Conversion Ratio.

       (c) Conversion Following IPO.

              (i) Not later than the 25th day following the date of the final
prospectus filed with the SEC in connection with the IPO (the "IPO Prospectus
Delivery Termination Date"), the Corporation shall give written notice to each
holder of Series A Preferred stating that (i) the IPO has been completed and
(ii) the Series A Preferred then outstanding will convert, without any further
action on the part of the Corporation or the holder of Series A Preferred, into
shares of Common Stock at the Floating Conversion Ratio (as defined below)
unless, on the fortieth (40th) day immediately following the IPO Prospectus
Delivery Termination Date, unless on or prior to such fortieth (40th) day such
holder gives written notice (a "Non-Conversion Notice") to the Corporation that
such holder desires that such holder's shares of Series A Preferred not be
converted into shares of Common Stock pursuant to Section 6(c)(ii).

              (ii) In the event that the Corporation does not receive a
Non-Conversion Notice from a holder of Series A Preferred on or prior to the
fortieth (40th) day immediately following the IPO Prospectus Delivery
Termination Date, then the shares of Series A Preferred owned by such holder
will convert, without any further action on the part of the Corporation or such
holder, into shares of Common Stock at the Floating Conversion Ratio.

              (iii) The Floating Conversion Ratio shall mean, with respect to
each share of Series A Preferred, a number of shares of Common Stock determined
by multiplying one by a fraction, the numerator of which is the Liquidation
Value (without the inclusion of any accrued but unpaid dividends), determined as
of the applicable Conversion Date (as defined below), and the denominator of
which is the price to the public of a share of the Common Stock in the IPO.

              (iv) Nothing in this Section 6(c) shall prevent a holder of Series
A Preferred from giving a Put Notice pursuant to Section 4(a) hereof prior to
the effectiveness of the conversion of Series A Preferred into Common Stock
pursuant to Section 6(c)(ii), and, in the event that a holder of Series A
Preferred gives a Put Notice prior to the effectiveness of such conversion, the
Corporation will be obligated to redeem the Series A Preferred subject to such
Put Notice in accordance with the provisions of Section 4(a).

       (d) Closing on the Conversion Date.

              (i) As promptly as possible after a Corporation-Elected Conversion
Date or a Holder-Elected Conversion Date or the date of a conversion effected in
accordance with Section 6(c) hereof (each, a "Conversion Date"), but in any
event within five business days thereafter, the Corporation shall deliver or
cause to be delivered to or for the account of the holders of the converted
shares of Series A Preferred: (A) payment in cash, out of funds legally
available therefor, in an amount equal to all accrued dividends (whether or not
declared or currently payable) with respect to each share converted which have
not been paid prior to the applicable Conversion Date; (B) in lieu of any
fractional shares to which the holder would otherwise be entitled, payment in
cash, out of funds legally available therefor, in an amount equal to such
fraction of a share multiplied by the price to the public of a share of the
Common Stock in the IPO; (C) a certificate or certificates representing the
number of shares of Common Stock issuable by reason of such conversion in such
name or names and such denomination or denominations as the converting holder
has specified; and (D) a certificate representing any shares of Series A
Preferred which were represented by the certificate or certificates delivered to
the Corporation in connection with such conversion but which were not converted.

              (ii) If the Corporation is not permitted under applicable law to
make the cash payment under subparagraph (ii) above, the Corporation shall make
such payments to the converting holder as soon thereafter as funds of the
Corporation are legally available for such payment. At the request of any such
converting holder in such case, the Corporation shall provide such holder with
written evidence of its obligation to such holder.

              (iii) The issuance or delivery of certificates for shares of
Common Stock upon conversion of Series A Preferred shall be made without charge
to the holders of such Series A Preferred for any issuance tax in respect
thereof or other cost incurred by the Corporation in connection with such
conversion and the related issuance of shares of Common Stock; provided,
however, that the Corporation shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
such certificate in a name other than that of the holder of shares of Series A
Preferred converted.

       (e) No Dividends After Conversion Date. No shares of Series A Preferred
to be converted shall be entitled to any dividends accruing after the applicable
Conversion Date with respect to such shares. On such date, all rights
attributable to such shares shall cease, such shares shall no longer be deemed
to be issued and outstanding and the persons or persons in whose name or names
any certificate or certificates for shares of Common Stock are to be issued upon
such conversion will be deemed to have become the holder or holders of record of
the shares of Common Stock represented thereby. In the event certificates
representing the shares of Series A Preferred to be converted are not delivered
on the applicable Conversion Date, such certificates will thereafter represent
only the right to receive shares of Common Stock upon their surrender.

       (f) Subdivision or Combination of Common Stock. If the Corporation at any
time subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its outstanding shares of Common Stock into a
greater number of shares, the Equivalent Basis Conversion Ratio and the Floating
Conversion Ratio (each, a "Conversion Ratio") in effect

                                      -13-


<PAGE>   14


immediately prior to such subdivision shall be proportionately increased, and if
the Corporation at any time combines (by reverse stock split or otherwise) one
or more classes of its outstanding shares of Common Stock into a smaller number
of shares, each Conversion Ratio in effect immediately prior to such combination
shall be proportionately decreased; provided, however, the issuance by the
Corporation of additional shares of Common Stock in an IPO or otherwise
(including without limitation (i) upon the exercise of any options to purchase
Common Stock which may have been granted from time to time by the Corporation or
(ii) as dividends on any series of Preferred Stock) for cash, property or
services shall not result in any adjustment of either Conversion Ratio. Promptly
following any such adjustment of either Conversion Ratio, the Corporation shall
give written notice thereof to all holders of Series A Preferred, setting forth
in reasonable detail and certifying the calculation and the effective date of
such adjustment.

       (g) Sale of Assets, Merger, Consolidation or Change of Control. In the
event of (i) any sale of all or substantially all of the Corporation's assets in
one transaction or series of transactions, (ii) any merger or consolidation
which involves the Corporation in which the Corporation is not the surviving
entity or (iii) any transaction after which the combined voting power of the
Corporation then held by persons other than the holders of voting stock as of
the date of the closing of Acquisition Agreements constitute 50% or more of the
combined voting power of the Corporation outstanding as of the date of the
consummation of such transaction (a "Reorganization Transaction"), prior to the
consummation of such Reorganization Transaction, the Corporation shall make
appropriate provisions to insure that each of the holders of Series A Preferred
shall thereafter have the right to acquire and receive, such shares of stock,
securities or assets as such holder would have received in connection with such
Reorganization Transaction if such holder had converted its Series A Preferred
immediately prior thereto.

       (h) Reservation of Common Stock. So long as any shares of the Series A
Preferred remain outstanding, the Corporation will at all times reserve from its
authorized Common Stock a sufficient number of shares to provide for the
conversion rights herein set forth and will take such corporate action, in the
event of an adjustment in either Conversion Ratio, as may be necessary in order
that it may validly and legally issue fully paid and nonassessable shares of
Common Stock upon conversion of the Series A Preferred.

       Section 7. Lost Share Certificates. In the event a holder of shares of
Series A Preferred is unable to deliver physical certificates representing such
shares for redemption or conversion, such holder, in lieu of delivering such
certificates, must notify the Corporation, and any transfer agent that the
Corporation may request, that such certificates have been lost, stolen, or
destroyed and execute an agreement reasonably satisfactory to the Corporation in
its sole discretion to indemnify the Corporation from any loss incurred by it in
connection therewith. In such event, such notice and agreement must be received
by the Corporation not less than ten days in advance of the applicable
Redemption Date or Conversion Date, as the case may be.

       Section 8. Registration Books; Record Holders. The Corporation will keep,
or cause to be kept, at its principal office (or at the office of its agent for
such purpose) proper books in which the names and addresses of the holders of
shares of Series A Preferred issued by the Corporation shall

                                      -14-


<PAGE>   15


be registered and in which transfers of such shares may be registered. The
Corporation may treat the registered holder of any shares of Series A Preferred
as the absolute owner thereof for the purpose of receiving all dividends and
redemption payments thereon and for all other purposes, and the Corporation
shall not be affected by any notice or knowledge to the contrary.

       Section 9. No Consent for Certain Actions. Except as provided in Section
5 hereof, no consent, approval or vote of the holders of Series A Preferred
shall be required for (i) the creation of any indebtedness of any kind of the
Corporation, (ii) the creation of any class of Junior Securities or Senior
Securities, (iii) the authorization of additional shares of any Junior Security
or Senior Securities, (iv) the issuance of shares of Junior Securities or Senior
Securities or (v) the repurchase or redemption of shares of Common Stock
pursuant to the provisions of the Acquisition Agreements.

       Section 10. No Preemptive Rights. The holders of Series A Preferred
shall not have preemptive rights to acquire additional, unissued or treasury
shares of capital stock of the Corporation.

       Section 11. Amendment and Waiver. The Corporation may not amend this
Certificate of Designations or waive compliance with any of the provisions
hereof without, in either instance, the affirmative vote (at a meeting) or the
written consent (with or without a meeting) of the holders of a majority of the
shares of Series A Preferred then outstanding.

       Section 12. Severability of Provisions. Whenever possible, each provision
hereof shall be interpreted in a manner as to be effective and valid under
applicable law, but if any provision hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof. If a court of competent
jurisdiction should determine that a provision hereof would be valid or
enforceable if a period of time were extended or shortened or a particular
percentage were increased or decreased, then such court may make such change as
shall be necessary to render the provision in question effective and valid under
applicable law.

       Section 13. Notices. Except as otherwise expressly provided hereunder,
all notices referred to herein shall be in writing and shall be delivered by
first class mail or by reputable overnight courier service, charges prepaid, and
shall be deemed to have been given when so mailed or sent (i) to the Corporation
(attention: Secretary) at its principal executive offices and (ii) to any
stockholder, at such holder's address as it appears in the stock records of the
Corporation or to such other address as the Corporation or holder, as the case
may be, shall have designated by notice similarly given.

<PAGE>   32

SECTION 1.3.        Form of Documents Delivered to Trustee.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all

such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify

         Any certificate or opinion of an officer of the Company or a Guarantor
may be based, insofar as it relates to legal matters, upon a certificate or
opinion of, or representations by, counsel, unless such officer knows, or in
the exercise of reasonable care should know, that the certificate or opinion or

opinion of, or representations by, an officer or officers of the Company or a

instruments under this Indenture, they may, but need not, be consolidated and

SECTION 1.4.        Acts of Holders; Record Dates.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company or a
Guarantor, as applicable. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this In-

                                     -25-

<PAGE>   33


denture and (subject to Section 6.1) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section.

         The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

         The ownership of Securities shall be proved by the Security Register.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of
the same Security and the Holder of every Security issued upon the registration
of transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee, the Company or a
Guarantor in reliance thereon, whether or not notation of such action is made
upon such Security.

         The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given or taken by Holders
of Securities, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities on such record date, and no other Holders, shall be
entitled to take the relevant action, whether or not such Holders remain
Holders after such record date; provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Record Expiration Date by
Holders of the requisite principal amount of Outstanding Securities on such
record date. Nothing in this paragraph shall prevent the Company from setting a
new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
nor shall anything in this paragraph be construed to render ineffective any
action taken pursuant to or in accordance with any other provision of this
Indenture by Holders of the requisite principal amount of Outstanding Notes on
the date such action is taken. Promptly after any record date is set pursuant
to this paragraph, the Company, at its own expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Record
Expiration Date to be given to the Trustee in writing and to each Holder of
Securities in the manner set forth in Section 1.6.

         The Trustee may but need not set any day as a record date for the
purpose of determining the Holders of Outstanding Securities entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.2, (iii) any request to institute
proceedings referred to in Section 5.7(ii) or (iv) any direction referred to in
Section 5.12. If any record date is set pursuant to this paragraph, the Holders
of Outstanding Securities on such record date, and no other

                                     -26-

<PAGE>   34


Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Record Expiration Date by Holders of the requisite
principal amount of Outstanding Securities on such record date. Nothing in this
paragraph shall be construed to prevent the Trustee from setting a new record
date for any action (whereupon the record date previously set shall
automatically and without any action by any Person be cancelled and of no
effect), nor shall anything in this paragraph be construed to render
ineffective any action taken pursuant to or in accordance with any other
provision of this Indenture by Holders of the requisite principal amount of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company's
expense, shall cause notice of such record date, the matter(s) to be submitted
for potential action by Holders and the applicable Record Expiration Date to be
given to the Company in writing and to each Holder of Securities in the manner
set forth in Section 1.6.

         With respect to any record date set pursuant to this Section, the
party hereto that sets such record date may designate any day as the "Record
Expiration Date" and from time to time may change the Record Expiration Date to
any earlier or later day, provided that no such change shall be effective
unless notice of the proposed new Record Expiration Date is given to the other
party hereto in writing, and to each Holder of Securities in the manner set
forth in Section 1.6, on or before the existing Record Expiration Date. If a
Record Expiration Date is not designated with respect to any record date set
pursuant to this Section, the party hereto that set such record date shall be
deemed to have initially designated the 180th day after such record date as the
Record Expiration Date with respect thereto, subject to its right to change the
Record Expiration Date as provided in this paragraph. Notwithstanding the
foregoing, no Record Expiration Date shall be later than the 180th day after
the applicable record date.

         Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

SECTION 1.5.        Notices to Trustee, the Company or a Guarantor.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

                  (i) the Trustee by any Holder or by the Company or a
          Guarantor shall be sufficient for every purpose hereunder if made,
          given, furnished or filed in writing or mailed, first class postage
          prepaid, or sent by overnight courier, or sent by telecopier, to or
          with the Trustee at its Corporate Trust Office, Attention: Corporate
          Trust Administration, or

                 (ii) the Company or a Guarantor by the Trustee or by any
          Holder shall be sufficient for every purpose hereunder (unless
          otherwise herein expressly provided) if in writing and mailed,
          first-class postage prepaid, to the Company or such Guarantor
          addressed to it at

                                     -27-

<PAGE>   35

         paragraph of this instrument, or at any other address previously
         furnished in writing to the Trustee by the Company.

SECTION 1.6.        Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders
is given by mail, neither the failure to mail or receive such notice, nor any
defect in any such notice, to any particular Holder shall affect the
sufficiency or validity of such notice. Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

SECTION 1.7.        Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under the Trust Indenture
Act to be part of and govern this Indenture, such provision of the Trust
Indenture Act shall control. If any provision of this Indenture modifies or
excludes any provision of the Trust Indenture Act that may be so modified or
excluded, such provision shall be deemed to be so modified or excluded, as the
case may be.

SECTION 1.8.        Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

SECTION 1.9.        Successors and Assigns.

         Without limiting Articles VIII and XIII hereof, all covenants and
agreements in this Indenture by each of the Company or the Guarantors shall
bind their respective successors and assigns, whether so expressed or not.

SECTION 1.10.       Separability Clause.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 1.13.       Legal Holidays.

payment of interest or principal (and premium, if any) need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect (including with respect to the accrual of interest) as if made on

other Securities pursuant to Section 3.4, 3.5, 3.6, 9.6 or 11.8 or in

by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register subject to the right of any Holder of
Securities in the principal amount of $500,000 or more to request payment by
wire transfer.

         The Company may be required to make a Change of Control Offer as
provided in Section 10.13, or an Asset Sale Offer as provided in Section 10.14.

         The Securities shall be redeemable as provided in Article XI and the
Securities.

         The Securities shall be subject to Defeasance and/or Covenant
Defeasance as provided in Article XII.

         The other terms and provisions contained in the Securities shall
constitute, and are hereby expressly made, a part of this Indenture.

         The Securities shall be issuable only in registered form without

SECTION 3.3.        Execution, Authentication, Delivery and Dating.

         The Initial Securities and the Trustee's certificate of authentication
shall be substantially in the form of Exhibit A-1 hereto. The Exchange
Securities and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A-2 hereto.

         The terms and provisions contained in the Securities annexed hereto as
Exhibits A-1 and A-2 shall constitute, and are hereby expressly, made, a part
of this Indenture and, to the extent applicable, the Company and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such
terms and provisions and to be bound thereby.

         Initial Securities shall be issued initially in the form of one or
more Global Securities, substantially in the form set forth in Exhibit A-1,
deposited with the Trustee, as custodian for the Depository, duly executed by
the Company and authenticated by the Trustee as hereinafter provided and shall
bear the legend set forth in Exhibit B. The aggregate principal amount of the
Global Securities may from time to time be increased or decreased by
adjustments made on the records of the Trustee, as custodian for the
Depository, as hereinafter provided.

         All Securities shall remain in the form of a Global Security, except
as provided herein.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Chief Executive Officer, its President or one of its
Vice Presidents or its Chief Financial Officer and attested by its Chief
Executive Officer, any of its Senior Vice Presidents, its Secretary or one of
its Assistant Secretaries. The signature of any of these officers on the
Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

         The Trustee shall authenticate (i) Initial Securities for original
issue in the aggregate principal amount not to exceed $250,000,000 in one or
more series, (ii) Private Exchange Securities from time to time only in
exchange for a like principal amount of Initial Securities and (iii)
Unrestricted Securities from time to time only (x) in exchange for a like
principal amount of Initial Securities or (y) in an aggregate principal amount
of not more than $250,000,000 over the sum of the aggregate principal amount of
(A) Initial Securities then outstanding, (B) Private Exchange Securities then
outstanding and (C) Unrestricted Securities issued in accordance with (iii)(x)
above. Each Company Order shall specify the amount of Securities to be
authenticated and the date on which the Securities are to be authenticated,
whether the Securities are to be Initial Securities, Private Exchange
Securities or

                                     -31-

<PAGE>   39


Unrestricted Securities and such other information as the Trustee may reasonably
request. In addition, with respect to authentication pursuant to clause (ii) or
(iii) of the first sentence of this paragraph, the first such written order
from the Company shall be accompanied by an Opinion of Counsel of the Company
in a form reasonably satisfactory to the Trustee stating that the issuance of
the Private Exchange Securities or the Unrestricted Securities, as the case may
be, does not give rise to an Event of Default, complies with this Indenture and
has been duly authorized by the Company.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

SECTION 3.4.        Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

         If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 10.2, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities
of authorized denominations and of a like tenor. Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

SECTION 3.5.        Registration; Registration of Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 10.2 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as the Company may prescribe, the Company shall provide
for the registration of Securities and of transfers of Securities. The Trustee
is hereby appointed the initial "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.

         Subject to Sections 3.13 and 3.14 of this Indenture, upon surrender
for registration of transfer of any Security at an office or agency of the
Company designated pursuant to Section 10.2 for such

                                     -32-

<PAGE>   40


purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denomination and of a like aggregate principal
amount and tenor.

         At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations and of a like aggregate principal
amount and tenor, upon surrender of the Securities to be exchanged at such
office or agency. Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.4, 9.6 or 11.8 or in accordance with any Change
of Control Offer pursuant to Section 10.13 or any Asset Sale Offer pursuant to
Section 10.14, and in any such case not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange any Security during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities selected for redemption under Section 11.4 and ending at the close
of business on the day of such mailing, (ii) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part or (iii) to
register the transfer of any Securities other than Securities having a
principal amount of $1,000 or integral multiples thereof.

SECTION 3.6.        Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security and (ii) such Security or indemnity as may be required by them to save
each of them and any agent of each of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security has been acquired by a
bona fide purchaser, the Company shall execute, and upon its request the
Trustee shall authenticate and deliver, in lieu of any such

                                     -33-

<PAGE>   41


destroyed, lost or stolen Security, a new Security of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion
may, instead of, issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 3.7.        Payment of Interest; Rights Preserved.

         Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more predecessor securities) is registered
at the close of business on the Regular Record Date for such interest payment.

         Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities (or their
         respective predecessor securities) are registered at the close of
         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Company
         shall notify the Trustee in writing of the amount of Defaulted
         Interest proposed to be paid on each Security and the date of the
         proposed payment, and at the same time the Company shall deposit with
         the Trustee an amount of money equal to the aggregate amount proposed
         to be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit prior to the
         date of the proposed payment, such money when deposited to be held in
         trust for the benefit of the Persons entitled to such Defaulted
         Interest as in this clause provided. Thereupon the Trustee shall fix a
         Special Record Date for the payment of such Defaulted Interest

                                     -34-

<PAGE>   42


         which shall be not more than 15 days and not less than 10 days prior
         to the date of the proposed payment and not less than 15 days after
         the receipt by the Trustee of the notice of the proposed payment. The
         Trustee shall promptly notify the Company of such Special Record Date
         and, in the name and at the expense of the Company, shall cause notice
         of the proposed payment of such Defaulted Interest and the Special
         Record Date therefor to be given to each Holder in the manner
         specified in Section 1.6, not less than 10 days prior to such Special
         Record Date. Notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor having been so mailed, such
         Defaulted Interest shall be paid to the Persons in whose names the
         Securities (or their respective predecessor securities) are registered
         at the close of business on such Special Record Date and shall no
         longer be payable pursuant to the following clause (2).

                  (2) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Securities may be listed, and upon
         such notice as may be required by such exchange, if, after notice
         given by the Company to the Trustee of the proposed payment pursuant
         to this Clause, such manner of payment shall be deemed practicable by
         the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

SECTION 3.8.        Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 3.7) interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 3.9.        Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or tendered and accepted pursuant to any Change of Control
Offer pursuant to Section 10.13 or any Asset Sale Offer pursuant to Section
10.14 shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee and shall be promptly cancelled by it. The Company may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in
any manner whatsoever, and all Securities so delivered shall be promptly
cancelled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities cancelled as provided in this Section, except as
expressly permitted by this Indenture. All cancelled Securities held by the
Trustee shall be disposed of in the customary manner by the Trustee unless
otherwise directed by a Company Order.

                                     -35-

<PAGE>   43


SECTION 3.10.       Computation of Interest.

         Interest on the Securities shall be computed on the basis of a 360-day
year comprised of twelve 30-day months.

SECTION 3.11.       CUSIP and CINS Numbers.

         The Company in issuing the Securities may use "CUSIP" and "CINS"
numbers (if then generally in use), and, if so, the Trustee shall use the CUSIP
or CINS numbers in notices of redemption or repurchase as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption or repurchase and that reliance may be
placed only on the other identification numbers printed on the Securities, and
any such redemption or repurchase shall not be affected by any defect in or
omission of such numbers.

         In the event that the Company shall issue and the Trustee shall
authenticate any Securities issued under this Indenture subsequent to the Issue
Date pursuant to clauses (i) and (iii) of the first sentence of the eighth
paragraph of Section 3.3, the Company shall use its best efforts to obtain the
same "CUSIP" number for such Securities as is printed on the Securities
outstanding at such time; provided, however, that if any series of Securities
issued under this Indenture subsequent to the Issue Date is determined,
pursuant to an Opinion of Counsel of the Company in a form reasonably
satisfactory to the Trustee, to be a different class of security than the
Securities outstanding at such time for federal income tax purposes, the
Company may obtain a "CUSIP" number for such Securities that is different than
the "CUSIP" number printed on the Securities then outstanding. Notwithstanding
the foregoing, all Securities issued under this Indenture shall vote and
consent together on all matters as one class and no series of Securities will
have the right to vote or consent as a separate class on any matter.

SECTION 3.12.       Deposits of Monies.

         Except to the extent payment of interest is made by the Company's
check or wire transfer pursuant to Section 3.1, prior to 11:00 a.m. New York
City time on each Interest Payment Date, Redemption Date, Stated Maturity, and
Purchase Date, the Company shall deposit with the Paying Agent in immediately
available funds money sufficient to make cash payments, if any, due on such
Interest Payment Date, Redemption Date, Stated Maturity and Purchase Date, as
the case may be, in a timely manner which permits the Paying Agent to remit
payment to the Holders on such Interest Payment Date, Redemption Date, Stated
Maturity, and Purchase Date, as the case may be.

SECTION 3.13.       Book-Entry Provisions for Global Securities.

         (a) The Global Securities initially shall (i) be registered in the
name of the Depository or the nominee of such Depository, (ii) be delivered to
the Trustee as custodian for such Depository and (iii) bear legends as set
forth in Exhibit B hereto.

         Members of, or participants in, the Depository ("Agent Members") shall
have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depository, or the

                                     -36-

<PAGE>   44


Trustee as its custodian, or under any Global Security, and the Depository may
be treated by the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner of the Global Securities for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depository or impair, as between the Depository and its Agent Members, the
operation of customary practices governing the exercise of the rights of a
Holder of any Security.

         (b) Transfer of Global Securities shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Securities may not be
transferred or exchanged for physical securities, except that physical
securities shall be transferred to all beneficial owners in exchange for their
beneficial interests in Global Securities if (i) the Depository notifies the
Company that it is unwilling or unable to continue as Depository for any Global
Security, or that it will cease to be a "Clearing Agency" under the Exchange
Act, and in either case a successor Depository is not appointed by the Company
within 90 days of such notice or (ii) an Event of Default has occurred and is
continuing and the Security Registrar has received a written request from the
Depository to issue physical securities.

         (c) The Holder of any Global Security may grant proxies and otherwise
authorize any Person, including Agent Members and Persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Securities.

SECTION 3.14.       Special Transfer Provisions.

         (a) Transfers to QIBs. The following provisions shall apply with
respect to the registration of any proposed transfer of an Initial Security and
the transfer of the beneficial interest in an Initial Security to a QIB: the
Security Registrar shall register the transfer of any Initial Security, whether
or not such Security bears the Private Placement Legend, and the transfer of
the beneficial interest in an Initial Security may be made if (x) the requested
transfer is after the second anniversary of the Issue Date; provided, however,
that neither the Company nor any Affiliate of the Company has held any
beneficial interest in such Security, or portion thereof, at any time on or
prior to the second anniversary of the Issue Date and such transfer can
otherwise be lawfully made under the Securities Act without registering such
Initial Security thereunder, (y) in the case of the registration of a transfer
by the Security Registrar, such transfer is being made by a proposed transferor
who has checked the box provided for on the form of Security stating, or has
otherwise advised the Company and the Security Registrar in writing, that the
sale has been made in compliance with the provisions of Rule 144A to a
transferee who has signed the certification provided for on the form of
Security stating, or has otherwise advised the Company and the Security
Registrar in writing, that it is purchasing the Security for its own account or
an account with respect to which it exercises sole investment discretion and
that it and any such account is a QIB within the meaning of Rule 144A, and is
aware that the sale to it is being made in reliance on Rule 144A and
acknowledges that it has received such information regarding the Company as it
has requested pursuant to Rule 144A or has determined not to request such
information and that it is aware that the transferor is relying upon its
foregoing representations in order to claim the exemption from registration
provided by Rule 144A or (z) in the case of the transfer of the beneficial
interest in an Initial Security (other than a transfer by an Agent Member, to
which

                                     -37-

<PAGE>   45


clause (ii) below shall apply), the transfer is made in accordance with Rule
144A under the Securities Act.

         (b) Private Legend. Upon the registration of transfer, exchange or
replacement of Securities not bearing the Private Placement Legend, the
Security Registrar shall deliver Securities that do not bear the Private
Placement Legend. Upon the registration of transfer, exchange or replacement of
Securities bearing the Private Placement Legend, the Security Registrar shall
deliver only Securities that bear the Private Placement Legend unless (i) the
circumstances contemplated by clause (x) of Section 3.14(a) exists, (ii) there
is delivered to the Security Registrar an opinion of counsel reasonably
satisfactory to the Company and the Trustee to the effect that neither such
legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act or (iii) such
Security has been sold pursuant to an effective registration statement under
the Securities Act.

         (c) Other Transfers. If a Holder proposes to transfer a Security
constituting a Restricted Security pursuant to any exemption from the
registration requirements of the Securities Act other than as provided for by
Section 3.14(a) and (b), the Security Registrar shall only register such
transfer or exchange if such transferor delivers an opinion of counsel
satisfactory to the Company and the Security Registrar that such transfer is in
compliance with the Securities Act and the terms of this Indenture.

         (d) General. By its acceptance of any Security bearing the Private
Placement Legend and by its ownership of a beneficial interest therein, each
Holder of such a Security and each owner of a beneficial interest therein
acknowledges the restrictions on transfer of such Security and of beneficial
interests therein set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Security and beneficial interests
therein only as provided in this Indenture.

         The Security Registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 3.13 or this Section
3.14. The Company shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon
the giving of reasonable prior written notice to the Security Registrar.

         This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for), and the Trustee, on demand of and at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

                  (1)      either

                  destroyed, lost or stolen and which have been replaced or
                  repaid as provided in Section 3.6 and (ii) Securities for
                  whose payment money has theretofore been deposited in trust

                  provided in Section 10.3) have been delivered to the Trustee
                  for cancellation; or

                           (B) all such Securities not theretofore delivered to

                  have been destroyed, lost or stolen and which have been

determine, to the Persons entitled thereto, of the principal (and premium, if

         of such Guarantors denies its liability under its Guaranty (other than
         by reason of release of such Guarantor in accordance with the terms of
         this Indenture).

SECTION 5.2.        Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than those covered by clause (7) or (8)
of Section 5.1 with respect to the Company) shall occur and be continuing, the
Trustee, by notice to the Company, or the Holders of at least 25% in aggregate
principal amount of the Securities then Outstanding, by notice to the Trustee
and the Company, may declare the principal of, premium, if any, and accrued and
unpaid interest, if any, on all of the Outstanding Securities due and payable
immediately, upon which declaration, all amounts payable in respect of the
Securities shall be due and payable. If an Event of Default specified in clause
(7) or (8) of Section 5.1 occurs and is continuing, then the principal of,
premium, if any, and accrued and unpaid interest, if any, on all the
Outstanding Securities shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of Securities.

         After a declaration of acceleration under this Indenture, but before a
judgment or decree for payment of the money due has been obtained by the
Trustee, the Holders of a majority in aggregate principal amount of the
Outstanding Securities, by written notice to the Company and the Trustee, may
rescind such declaration if:

                  (1) the Company or any Guarantor has paid or deposited with
         the Trustee a sum sufficient to pay

                           (A) all sums paid or advanced by the Trustee under
                  this Indenture and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel,

                                     -42-

                           (B) all overdue interest on all Securities,

                           (C) the principal of and premium, if any, on any
                  Securities which have become due otherwise than by such
                  declaration of acceleration and interest thereon at the rate
                  borne by the Securities, and

                           (D) to the extent that payment of such interest is
                  lawful, interest upon overdue interest and overdue principal
                  at the rate set forth in the Securities which has become due
                  otherwise than by such declaration of acceleration;

                  (2) the rescission would not conflict with any judgment or
         decree of a court of competent jurisdiction; and

                  (3) all Events of Default, other than the nonpayment of
         principal of, premium, if any, and interest on the Securities that
         have become due solely by such declaration of acceleration, have been
         cured or waived.

         No such rescission shall affect any subsequent default or impair any
right consequent thereto.

SECTION 5.3.        Collection of Indebtedness and Suits for Enforcement by
                    Trustee.

         The Company and each Guarantor covenants that if

                  (i) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                  (ii) default is made in the payment of the principal of (or
         premium, if any, on) any Security on the due date for payment thereof,
         including, with respect to any Security required to have been
         purchased pursuant to a Change of Control Offer or an Asset Sale Offer
         made by the Company, at the Purchase Date thereof,

the Company or such Guarantor will, upon demand of the Trustee, pay to it, for
the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal (and premium, if any) and interest,
and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue
interest, at the rate provided by the Securities, and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

         In addition to the rights and powers set forth in Section 317(a) of
the Trust Indenture Act, the Trustee shall be entitled to file such other
papers or documents as may be necessary or advisable in order to have the
claims of the Trustee and of the Holders of the Securities allowed in any
judicial proceeding relative to the Company, any Guarantor or any other obligor
upon the Securities, its creditors, or its property, and to collect and receive
any moneys or other property payable or deliverable on any such claims, and to
distribute the same after the deduction of its charges and expenses; and any
receiver, assignee or trustee in bankruptcy or reorganization is hereby
authorized by each of

                                     -43-

<PAGE>   51


the Holders to make such payments to the Trustee, and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for compensation and expenses,
including counsel fees incurred by it up to the date of such distribution.

         If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 5.4.        Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Company, a
Guarantor (or any other obligor upon the Securities), its property or its
creditors, the Trustee shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the Trust
Indenture Act in order to have claims of the Holders and the Trustee allowed in
any such proceeding. In particular, the Trustee shall be authorized to collect
and receive any moneys or other property payable or deliverable on any such
claims and to distribute the same; and any custodian, receiver, assignee,
trustee, liquidator, sequestrator or other similar official in any such
judicial proceeding is hereby authorized by each Holder to make such payments
to the Trustee and, in the event that the Trustee shall consent to the making
of such payments directly to the Holders, to pay to the Trustee any amount due
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.7.

         No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors,
or other similar committee.

SECTION 5.5.        Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
distributions and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 5.6.        Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on ac-

         Section 6.7;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Securities in

         collected, ratably, without preference or priority of any kind,
         according to the amounts due and payable on such Securities for
         principal (and premium, if any) and interest, respectively;

                  THIRD: To the payment of any and all other amounts due under
         this Indenture, the Securities or the Guarantees; and

                  FOURTH: To the Company (or such other Person as a court of
         competent jurisdiction may direct).

SECTION 5.7.        Limitation on Suits.

         Subject to Section 5.8, no Holder of any Security shall have and right
to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

                  (i) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default;

                  (ii) the Holders of not less than 25% in principal amount of
         the Outstanding Securities shall have made written request to the
         Trustee to institute proceedings in respect of such Event of Default
         in its own name as Trustee hereunder;

                  (iii) such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                  (iv) the Trustee for 45 days after its receipt of such
         notice, request and offer of indemnity has failed to institute any
         such proceeding; and

                  (v) no direction inconsistent with such written request has
         been given to the Trustee during such 45-day period by the Holders of
         a majority in principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

SECTION 5.8.        Unconditional Right of Holders To Receive Principal, Premium
                    and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 3.7) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date or in the case of a Change of Control Offer or an Asset Sale Offer made by
the Company and required to be accepted as to such Security, on the relevant
Purchase Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

SECTION 5.9.        Restoration of Rights and Remedies.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, each Guarantor, the Trustee and
the Holders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted,
subject to the determination in such proceeding.

SECTION 5.10.       Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 5.11.       Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 5.12.       Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee, provided that

                  (i) such direction shall not be in conflict with any rule of
         law or with this Indenture, and

                                     -46-

<PAGE>   54


                  (ii) the Trustee may take any other action deemed proper by
         the Trustee which is not inconsistent with such direction.

SECTION 5.13.       Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities may on behalf of the Holders of all the Securities waive
any past default hereunder and its consequences, except a default

                  (i) in the payment of the principal of (or premium, if any)
         or interest on any Security (including any Security which is required
         to have been purchased pursuant to a Change of Control Offer or an
         Asset Sale Offer which has been made by the Company), or

                  (ii) in respect of a covenant or provision hereof which under
         Article IX cannot be modified or amended without the consent of the
         Holder of each Outstanding Security affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 5.14.       Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit
to file an undertaking to pay the costs of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in
the Trust Indenture Act; provided, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company
or a Guarantor, in any suit instituted by the Trustee, in any suit instituted
by any Holder or group of Holders, holding in the aggregate more than 10% in
principal amount of the Outstanding Securities, or in any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Security on or after the Stated Maturity expressed
in such Security (or, in the case of redemption, on or after the Redemption
Date or, in the case of a Change of Control Offer or an Asset Sale Offer, made
by the Company and required to be accepted as to such Security, on the
applicable Purchase Date, as the case may be).

SECTION 5.15.       Waiver of Stay or Extension Laws.

         The Company and each Guarantor covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any usury, stay or
extension law wherever enacted, now or at any time hereafter in force, which
may affect the covenants or the performance of this Indenture; and the Company
and each Guarantor (to the extent that it may lawfully do so) hereby expressly
waives all benefit or advantage of any such law and covenants that it will not
hinder, delay or impede the execution of any

                                     -47-

power herein granted to the Trustee, but will suffer and permit the execution
of every such power as though no such law had been enacted.

                                  THE TRUSTEE


SECTION 6.1.        Certain Duties and Responsibilities.

         (a)      Except during the continuance of an Event of Default,

                  (i) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture, and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

                  (ii) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements
         of this Indenture; but in the case of any such certificates or
         opinions which by the provisions hereof are specifically required to
         be furnished to the Trustee, the Trustee shall be under a duty to
         examine the same to determine whether or not they conform to the
         requirements of this Indenture but need not verify the contents
         thereof.

         (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent Person would exercise or use under the circumstances in the conduct of
such Person's own affairs.

         (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent misconduct, except that no
provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers under
this Indenture, unless the Trustee has received security and indemnity
satisfactory to it against any loss, liability or expense. The Trustee shall
not be liable for any error of judgment unless it is proved that the Trustee
was negligent in the performance of its duties hereunder.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 6.1.

SECTION 6.2.        Notice of Defaults.

         Within 30 days after the occurrence of any Default, the Trustee shall
transmit by mail to all Holders, as their names and addresses appear in the
Security Register, notice of such Default

                                     -48-

<PAGE>   56


hereunder known to the Trustee, unless such Default shall have been cured or
waived; provided, however, that, except in the case of a Default in the payment
of the principal of, premium, if any, or interest on any Security, the Trustee
shall be protected in withholding such notice if and so long as a trust
committee of Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the interest of the Holders.

SECTION 6.3.        Certain Rights of Trustee.

         Subject to the provisions of Section 6.1:

                  (a) the Trustee may conclusively rely as to the truth of the
         statements and correctness of the opinions expressed therein and shall
         be fully protected in acting or refraining from acting upon any
         resolution, Officer's Certificate, certificate of auditors or any
         other certificate, statement, instrument, opinion, report, notice,
         request, direction, consent, order, bond, debenture, note, other
         evidence of indebtedness or other paper or document believed by it to
         be genuine and to have been signed or presented by the proper party or
         parties;

                  (b) any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order
         and any resolution of the Board of Directors of the Company may be
         sufficiently evidenced by a Board Resolution of the Company;

                  (c) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officer's
         Certificate;

                  (d) the Trustee may consult with counsel of its selection and
         the advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;

                  (e) the Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by this Indenture at the request
         or direction of any of the Holders pursuant to this Indenture, unless
         such Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction;

                  (f) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled (subject to
         reasonable confidentiality arrangements as may be proposed by the
         Company or any Guarantor) to make

                                     -49-

         reasonable examination (upon prior notice and during regular business
         hours) of the books, records and premises of the Company or a
         Guarantor, personally or by agent or attorney;

                  (g) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys or custodians or nominees and the Trustee
         shall not be responsible for the supervision of, or any misconduct or
         negligence on the part of any agent or attorney appointed with due
         care by it hereunder;

                  (h) the Trustee shall not be liable for any action taken,
         suffered, or omitted to be taken by it in good faith and reasonably
         believed by it to be authorized or within the discretion or rights or
         powers conferred upon it by this Indenture; and

                  (i) in the event that the Trustee is also acting as
         Authenticating Agent, Paying Agent or Security Registrar hereunder,
         the rights and protections afforded to the Trustee pursuant to this
         Article VI shall also be afforded to such Authenticating Agent, Paying
         Agent and Security Registrar.

SECTION 6.4.        Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. The Trustee makes no representations as
to the validity or sufficiency of this Indenture or of the Securities. The
Trustee shall not be accountable for the use or application by the Company of
Securities or the proceeds thereof.

SECTION 6.5.        May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company or any Guarantor, in its individual
or any other capacity, may become the owner or pledgee of Securities and,
subject to Sections 6.8 and 6.13, may otherwise deal with the Company or a
Guarantor with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

SECTION 6.6.        Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated

otherwise agreed in writing with the Company.

SECTION 6.7.        Compensation and Reimbursement.

         The Company agrees

                  (1) to pay to the Trustee from time to time such reasonable
         compensation as the Company and the Trustee shall from time to time
         agree in writing for all services rendered by

                                     -50-

<PAGE>   58


         it hereunder (which compensation shall not be limited by any provision
         of law in regard to the compensation of a trustee of an express
         trust);

                  (2) except as otherwise expressly provided herein, to
         promptly reimburse the Trustee upon its request for all reasonable
         expenses, disbursements and advances incurred or made by the Trustee
         in accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence or bad faith; and

                  (3) to indemnify the Trustee, its directors, officers, agents
         and employees for, and to hold them harmless against, any and all
         loss, damage, claim, liability or expense incurred without negligence
         or bad faith on its part, including taxes (other than taxes based
         upon, measured by or determined by the revenue or income of the
         Trustee), arising out of or in connection with the acceptance or
         administration of this trust, including the costs and expenses of
         defending itself against any claim or liability in connection with the
         exercise or performance of any of its powers or duties hereunder.

property and funds held by it hereunder for any amount owing to it pursuant to
this Section 6.7, except with respect to funds held in trust for the benefit of
the Holders of particular Securities.

         When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.1(7) or Section 5.1(8), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

reports of condition at least annually, pursuant to law or to the requirements
of a Federal or State supervising or examining authority, then for the purposes
of this Section and to the extent permitted by the Trust Indenture Act, the
combined capital and surplus of such Person shall be deemed to be its combined

applicable requirements of Section 6.9.

         (b) The Trustee may resign at any time by giving written notice
thereof to the Company. if an instrument of acceptance by a successor Trustee

any court of competent jurisdiction for the appointment of a successor Trustee.

         (c) The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Securities, delivered to the
Trustee and to the Company.

         written request therefor by the Company or by any Holder who has been
         a bona fide Holder of a Security for at least six months, or

                  (ii) the Trustee shall cease to be eligible under Section 6.9
         and shall fail to resign after written request therefor by the
         Company, any Guarantor or by any such Holder, or

                  (iii) the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent or a receiver of the Trustee or of
         its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation,

acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.11, become the
successor Trustee and supersede the successor Trustee appointed by the Company.

pursuant to Section 6.7(3) in connection with the exercise or performance by
the Trustee prior to its resignation or removal of any of its powers or duties
hereunder.

         (h) No Trustee under this Indenture shall be liable for any action or

the successor Trustee, such retiring Trustee shall, upon payment of its
charges, execute and deliver an instrument transferring to such successor

business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt

SECTION 6.13.       Preferential Collection of Claims Against the Company or a
                    Guarantor.

         If and when the Trustee shall be or become a creditor of the Company

subject to the provisions of the Trust Indenture Act regarding the collection
of claims against the Company or such Guarantor (or any such other obligor).

SECTION 6.14.       Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents which shall
be authorized to act on behalf of the Trustee to authenticate Securities issued
upon original issue and upon exchange, registration of transfer or partial
redemption or partial purchase or pursuant to Section 3.6, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $100,000,000 and subject to supervision or
examination by Federal or State authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall
be otherwise eligible under this Section, without the execution or filing of
any paper or any further act on the part of the Trustee or the Authenticating
Agent.

         An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6, to all Holders as their
names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance

                                     -54-

<PAGE>   62


of its appointment hereunder shall become vested with all the rights, powers
and duties of its predecessor hereunder, with like effect as if originally
named as an Authenticating Agent. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

         If an appointment is made pursuant to this Section, the Securities may
have endorsed thereon, in addition to the Trustee's certificate of
authentication, an alternative certificate of authentication in the following
form:

         This is one of the Securities described in the within-mentioned
Indenture.

         (b) The rights of Holders to communicate with other Holders with

otherwise dispose of all or substantially all of its properties and assets to,

Subsidiaries to enter into any such transaction or series of transactions if
such transaction or series of transactions, in the aggregate, would result in a
sale, assignment, conveyance, transfer, lease or other disposition of all or
substantially all of the properties and assets of the Company or the Company and

                  (1)      either:

                           (x) if the transaction or transactions is a merger or
                  consolidation, the Company or such Restricted Subsidiary, as

                           (y) the Person formed by such consolidation or into
                  which the Company or such Restricted Subsidiary, as the case
                  may be, is merged or to which the properties and assets of the
                  Company or such Restricted Subsidiary, as the case may be, are
                  disposed of (any such surviving Person or transferee Person
                  being the "Surviving Entity") shall be a corporation organized
                  and existing under the laws of the United States of America,
                  any state thereof or the District of Columbia and shall
                  expressly assume by a supplemental indenture executed and
                  delivered to the Trustee, in form satisfactory to the Trustee,
                  all the obligations of the Company under the Securities, this
                  Indenture and the Registration Rights Agreement and in each
                  case, this Indenture, the Securities and the Registration
                  Rights Agreement shall remain in full force and effect;

                  (2) immediately after giving effect to such transaction or
         series of transactions on a pro forma basis (including, without
         limitation, any Indebtedness incurred or anticipated to be incurred in
         connection with or in respect of such transaction or series of
         transactions), no Default or Event of Default shall have occurred and
         be continuing; and

                  (3) except in the case of any merger of the Company with any
         Restricted Subsidiary of the Company or any merger of Guarantors, in
         each case with no other Person, the Company or the Surviving Entity, as
         the case may be, after giving effect to such transaction or series of
         transactions on a pro forma basis on the assumption that the
         transaction or transactions had occurred on the first day of the period
         of four fiscal quarters ending immediately prior to the consummation of
         such transaction or transactions, with the appropriate adjustments with
         respect to such transaction or transactions being included in such pro
         forma calculation, could incur $1.00 of additional Indebtedness (other
         than Permitted Indebtedness) under Section 10.8 (assuming a market rate
         of interest with respect to such additional Indebtedness).

         In connection with any consolidation, merger, transfer, lease,
assignment or other disposition contemplated by the foregoing provisions of this
Section 8.1, the Company shall deliver, or cause to be delivered, to the
Trustee, in form and substance reasonably satisfactory to the Trustee, an
Officer's Certificate and an Opinion of Counsel, each stating that such

supplemental indenture in respect thereof (required under clause (1)(y) of this
Section 8.1) comply with the requirements of this Indenture. Each such Officer's
Certificate shall set forth the manner of determination of the ability to incur

SECTION 8.2.        Successor Substituted.

         Upon any consolidation or merger, or any sale, assignment, conveyance,
transfer, lease or disposition subject to and in accordance with Section 8.1,
the successor Person formed by such consolidation or into which the Company or
Restricted Subsidiary, as the case may be, is merged or the successor Person to
which such sale, assignment, conveyance, transfer, lease or disposition is made
shall succeed to, and be substituted for, and may exercise every right and power
of the Company under the Securities, this Indenture and/or the Registration
Rights Agreement, as applicable, with the same effect as if such successor had
been named as the Company in the Securities, this Indenture and/or in the
Registration Rights Agreement, as the case may be, and, except in the case of a
lease, the Company or such Restricted Subsidiary, as the case may be, shall be
automatically and unconditionally released and discharged from its obligations
thereunder.

         For all purposes of this Indenture and the Securities (including the
provisions of this Article VIII and Sections 10.8, 10.9 and 10.12), Subsidiaries

and the Restricted Subsidiaries in existence immediately prior to such
transaction or series of related transactions will be deemed to have been
incurred upon consummation of such transaction or series of related
transactions.

                  AMENDMENTS; WAIVERS; SUPPLEMENTAL INDENTURES


SECTION 9.1.        Amendments, Waivers and Supplemental Indentures Without
                    Consent of Holders.

         Without the consent of any Holders, the Company and each Guarantor,
when authorized by Board Resolutions, and the Trustee, at any time and from time
to time, may together amend, waive or supplement this Indenture, for any of the
following purposes:

                  (i) to evidence the succession of another Person to the
         Company or a Guarantor and the assumption by any such successor of the
         covenants of the Company or such Guarantor herein and in the Securities
         and to evidence the assumption of obligations under this Indenture and
         a Guaranty pursuant to Section 10.17; or

                  (ii) to add to the covenants of the Company or a Guarantor for
         the benefit of the Holders, or to surrender any right or power herein
         conferred upon the Company or a Guarantor; or

                  (iii) to secure the Securities pursuant to the requirements of
         Section 10.12 or otherwise; or




                                      -58-
<PAGE>   66

                  (iv) to comply with any requirements of the Commission in
         order to effect or maintain the qualification of this Indenture under
         the Trust Indenture Act; or

                  (v) to cure any ambiguity, to correct or supplement any
          provision herein which may be defective or inconsistent with any other
          provision herein, or to make any other provisions with respect to
          matters or questions arising under this Indenture which shall not be
          inconsistent with the provisions of this Indenture,

provided that (a) such amendment, waiver or supplement does not adversely affect
the rights of any Holder of Securities and (b) the Company shall have delivered
to the Trustee an Opinion of Counsel stating that such action pursuant to
clauses (i), (ii), (iii), (iv) or (v) above is permitted by this Indenture. The
Trustee shall not be obligated to enter into any such amendment or supplemental
indenture that adversely affects its own rights, duties or immunities under this
Indenture or otherwise.

SECTION 9.2.        Modifications, Amendments and Supplemental Indentures
                    with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities, by Act of said Holders delivered
to the Company and the Trustee, the Company and the Guarantors, when authorized
by Board Resolutions, and the Trustee may together modify, amend or supplement
this Indenture for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Indenture or of modifying in
any manner the rights of the Holders under this Indenture; provided, however,
that no such modification, amendment or supplemental indenture shall, without
the consent of the Holder of each Outstanding Security affected thereby,

                  (i) change the Stated Maturity of the principal of, or any
         installment of interest on, any Security, or reduce the principal
         amount of (or the premium, if any, on), or interest on, any Securities
         or alter the redemption provisions of the Securities,

                  (ii) change the currency in which any Securities or any
         premium or the interest thereon is payable,

                  (iii) reduce the above-stated percentage in principal amount

         amount of outstanding Securities necessary to waive compliance with
         provisions of this Indenture or to waive defaults under this Indenture,

                  (v) impair the right to institute suit for the enforcement of
         any payment on or with respect to the Securities or any Guaranty,

                  (vi) amend, change or modify the obligation of the Company to
         make and consummate a Change of Control Offer after the occurrence of a
         Change of Control or make and




                                      -59-
<PAGE>   67

         consummate an Asset Sale Offer with respect to any Asset Sale that has
         been consummated or modify any of the provisions or definitions with
         respect thereto,

                  (vii) modify or change any provision of this Indenture
         relating to the Guarantees in a manner adverse to the Holders of the
         Securities, or

                  (viii) modify or change any provision of this Indenture
         affecting the Subordination or ranking of the Securities or any
         Guaranty in a manner which adversely affects the holders of Securities.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed amendment or supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

         The Trustee shall join with the Company and each Guarantor in the
execution of such amended or supplemental indenture unless such amended or
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion but shall not be obligated to enter into such amendment or
supplemental indenture.

SECTION 9.3.        Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.1) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise;
provided that the Trustee shall enter into and execute all other supplemental
indentures which satisfy all applicable conditions under this Article IX.

SECTION 9.4.        Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

SECTION 9.5.        Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

<PAGE>   68

SECTION 9.6.        Reference in Securities to Supplemental Indentures.

         Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture, provided that any failure by the
Trustee to make such notation shall not affect the validity of the matter
provided for in such supplemental indenture or any Security or Guaranty
hereunder. If the Company shall so determine, new Securities so modified as to
conform, in the opinion of the Trustee, the Guarantors and the Company, to any
such supplemental indenture may be prepared and executed by the Company or
Guarantor and authenticated and delivered by the Trustee in exchange for
Outstanding Securities.

SECTION 9.7.        Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
covenant or condition set forth in Section 8.1, any covenant or condition
provided pursuant to Section 9.1(ii) or any covenant or condition set forth in
Sections 10.4 to 10.12 and 10.15 to 10.18, inclusive, if before the time for
such compliance the Holders of at least a majority in principal amount of the
Outstanding Securities shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such covenant or condition shall remain in full force and
effect.

SECTION 9.8.        No Liability for Certain Persons.

         No director, officer, employee, or stockholder of the Company, nor any
director, officer or employees of any Guarantor, as such, shall have any
liability for any obligations of the Company or any Guarantor under the
Securities, the Guarantees or this Indenture based on, in respect of, or by
reason of such obligations or their creation. Each Holder by accepting a
Security waives and releases all such liability. The foregoing waiver and
release is an integral part of the consideration for the issuance of the
Securities and the Guarantees.

SECTION 10.1.       Payment of Principal, Premium and Interest.

the Securities, this Indenture and the Registration Rights Agreement.




                                      -61-
<PAGE>   69

SECTION 10.2.       Maintenance of Office or Agency.

         The Company shall maintain an office or agency where Securities may be
presented or surrendered for payment, where Securities may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company or any Guarantor in respect of the Securities, the Guarantees and
this Indenture may be served. The Company shall give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands. In the event any such notice or demands are so made or served on the
Trustee, the Trustee shall promptly forward copies thereof to the Company.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations.
Further, if at any time there shall be no such office or agency in the City of
New York where the Securities may be presented or surrendered for payment, the
Company shall forthwith designate and maintain such an office or agency in the
City of New York in order that the Securities shall at all times be payable in
the City of New York. The Company shall give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency.

SECTION 10.3.       Money for Security Payments To Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent, it will,
on or before each due date of the principal of (and premium, if any) or interest
on any of the Securities, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents, the Company
will, prior to 11:00 a.m. New York City time on each due date of the principal
of (and premium, if any) or interest on any Securities, deposit with a Paying
Agent a sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held as provided by the Trust Indenture Act, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

         The Company shall cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will: (i) comply with the provisions of the Trust Indenture
Act applicable to it as Paying Agent and (ii) during the continuance of any
default by the Company (or any other obligor upon the Securities) in the making
of any payment in respect of the Securities, upon the written request of the
Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent as such.




                                      -62-
<PAGE>   70

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by such Paying Agent, such sums to be held by the Trustee upon the same
trusts as those upon which such sums were held by such Paying Agent; and, upon
such payment by any Paying Agent (other than the Company) to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in The City of New York, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

SECTION 10.4.       Existence; Activities.

         Subject to Article VIII, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
rights (charter and statutory) and material franchises; provided, however, that
the Company shall not be required to preserve any such right or franchise if the
Board of Directors of the Company in good faith shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders.

SECTION 10.5.       Maintenance of Properties.

         The Company shall cause all material properties used in the conduct of
its business or the business of any Restricted Subsidiary to be maintained and
kept in good condition, repair and working order (regular wear and tear
excepted), all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent the Company from disposing of any asset (subject to compliance with
Section 10.14) or from discontinuing the operation or maintenance of any of such
material properties if such discontinuance is, as determined by the Company in
good faith, desirable in the conduct of its business or the business of any
Restricted Subsidiary and not disadvantageous in any material respect to the
Holders.

<PAGE>   71

SECTION 10.6.       Payment of Taxes and Other Claims.

         The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any of its Restricted
Subsidiaries or upon the income, profits or property of the Company or any of
its Restricted Subsidiaries, and (2) all lawful material claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon
property of the Company or any of its Restricted Subsidiaries; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

SECTION 10.7.       Maintenance of Insurance.

         The Company shall, and shall cause its Restricted Subsidiaries to, keep
at all times all of their material properties which are of an insurable nature
insured against loss or damage with insurers believed by the Company to be
responsible to the extent that property of similar character is usually so
insured by corporations similarly situated and owning like properties in
accordance with good business practice. The Company shall, and shall cause its
Restricted Subsidiaries to, use the proceeds from any such insurance policy to
repair, replace or otherwise restore all material properties to which such
proceeds relate, provided, however, that the Company shall not be required to
repair, replace or otherwise restore any such material property if the Company
in good faith determines that such inaction is desirable in the conduct of the
business of the Company or any Restricted Subsidiary and not disadvantageous in
any material respect to the Holders.

SECTION 10.8.       Limitation on Indebtedness.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or in any manner become directly or indirectly liable, contingently or otherwise
(in each case, to "incur"), for the payment of any Indebtedness (including any
Acquired Indebtedness) other than Permitted Indebtedness; provided, however,
that the Company and any Guarantor will be permitted to incur Indebtedness
(including Acquired Indebtedness) if (A) the Consolidated Fixed Charge Coverage
Ratio of the Company is at least 2.0 to 1 and (B) no Default or Event of Default

SECTION 10.9.       Limitation on Restricted Payments.

         The Company will not, and will not permit any of its Restricted

                  (a) declare or pay any dividend or make any other distribution
         or payment on or in respect of Capital Stock of the Company or any of
         its Restricted Subsidiaries or make any payment to the direct or
         indirect holders (in their capacities as such) of Capital Stock of the

         than Redeemable Capital Stock) or in options, warrants or other rights
         to purchase Capital Stock of the Company (other than Redeemable




                                      -64-

         Capital Stock)) (other than the declaration or payment of dividends or
         other distributions to the extent declared or paid to the Company or
         any Guarantor);

                  (b) purchase, redeem, or otherwise acquire or retire for value
         any Capital Stock of the Company or any of its Restricted Subsidiaries

         Subsidiary);

                  (c) make any principal payment on, or purchase, defease,
         repurchase, redeem or otherwise acquire or retire for value, prior to
         any scheduled maturity, scheduled repayment, scheduled sinking fund
         payment or other Stated Maturity, any Subordinated Indebtedness (other
         than any such Subordinated Indebtedness owed by the Company or a
         Restricted Subsidiary); or

                  (d) make any Investment (other than any Permitted Investment)
         in any Person

(such payments or Investments described in the preceding clauses (a), (b), (c)
and (d) are collectively referred to as "Restricted Payments"), unless, after
giving effect to the proposed Restricted Payment (the amount of any such
Restricted Payment, if other than cash, shall be the Fair Market Value of the
asset(s) proposed to be transferred by the Company or such Restricted
Subsidiary, as the case may be, pursuant to such Restricted Payment), (A) no
Default or Event of Default shall have occurred and be continuing, (B) after
giving pro forma effect to such Restricted Payment, the Company would be able to
incur $1.00 of additional Indebtedness (other than Permitted Indebtedness)
pursuant to Section 10.8 and (C) the aggregate amount of all Restricted Payments
declared or made from and after the Issue Date would not exceed the sum of:

                  (1) 50% of the aggregate Consolidated Net Income of the
         Company accrued on a cumulative basis during the period beginning on
         April 1, 1999 and ending on the last day of the fiscal quarter of the
         Company ending immediately prior to the date of such proposed
         Restricted Payment for which consolidated financial statements are
         available (or, if such aggregate cumulative Consolidated Net Income of
         the Company for such period shall be a loss, minus 100% of such loss);

                  (2) the aggregate net cash proceeds received by the Company as
         capital contributions to the Company after the Issue Date and which
         constitute shareholders' equity of the Company in accordance with GAAP;

                  (3) the aggregate net cash proceeds received by the Company
         from the issuance or sale of Capital Stock (excluding Redeemable
         Capital Stock) of the Company to any Person (other than to a Subsidiary
         of the Company) after the Issue Date;

                  (4) the aggregate net cash proceeds received by the Company
         from any Person (other than a Subsidiary of the Company) upon the
         exercise of any options, warrants or rights to purchase shares of
         Capital Stock (other than Redeemable Capital Stock) of the Company
         after the Issue Date;




                                      -65-
<PAGE>   73

                  (5) the aggregate net cash proceeds received after the Issue
         Date by the Company from any Person (other than a Subsidiary of the
         Company) from the issuance and sale of debt securities that have been
         converted into or exchanged for Capital Stock of the Company (other
         than Redeemable Capital Stock) to the extent such debt securities were
         originally sold for cash, plus the aggregate amount of cash received by
         the Company (other than from a Subsidiary of the Company) at the time
         of such conversion or exchange;

                  (6) to the extent not otherwise included in the Company's
         Consolidated Net Income, in the case of the disposition or repayment of
         any Investment constituting a Restricted Payment after the Issue Date,
         an amount equal to the lesser of the return of capital with respect to
         such Investment and the initial amount of such Investment, in either
         case, less the cost of the disposition of such Investment;

                  (7) so long as the Designation (as defined in Section 10.18)
         thereof was treated as a Restricted Payment made after the Issue Date,
         with respect to any Unrestricted Subsidiary that has been redesignated
         as a Restricted Subsidiary after the Issue Date in accordance with
         Section 10.18 below, the Fair Market Value of the Company's interest in
         such Subsidiary at the time of such redesignation, provided, however,
         that such amount shall not in any case exceed the Designation Amount
         (as defined in Section 10.18) with respect to such Restricted
         Subsidiary upon its Designation; and

                  (8)      $4,000,000.

         For purposes of the preceding clause (C)(4), the value of the aggregate
net proceeds received by the Company upon the issuance of Capital Stock upon the
exercise of options, warrants or rights will be the net cash proceeds received
upon the issuance of such options, warrants or rights plus the incremental
amount received by the Company upon the exercise thereof.

         None of the foregoing provisions will prohibit, so long as, in the case
of clause (v) and (vi) below, there is no Default or Event of Default
continuing: (i) the payment of any dividend or distribution within 60 days after
the date of its declaration, if at the date of declaration such payment would be
permitted by the first paragraph of this covenant; (ii) the redemption,
repurchase or other acquisition or retirement of any shares of any class of
Capital Stock of the Company in exchange for, or out of the net cash proceeds of
a substantially concurrent issue and sale of, other shares of Capital Stock of
the Company (other than Redeemable Capital Stock) to any Person (other than to a
Subsidiary of the Company); provided, however, that such net cash proceeds are
excluded from clause (C) of the first paragraph of this Section 10.9; (iii) any

Subsidiary of the Company); provided, however, that any such net cash proceeds
are excluded from clause (C) of the first paragraph of this Section 10.9; or (2)
other Subordinated Indebtedness of the Company which (w) has no scheduled
principal payment prior to the 91st day after the Maturity Date, (x) has an
Average Life to Stated Maturity greater than the remaining Average Life to
Stated Maturity of the Securities and (y) is subordinated to the Securities to
at least the same extent as the Subordinated Indebtedness so purchased,
exchanged, redeemed,




                                      -66-
<PAGE>   74

acquired or retired; (iv) payments to purchase Capital Stock of the Company from

authorized representatives, upon the death, disability or termination of
employment of such employees, in aggregate amounts under this clause (iv) not to
exceed $1.0 million in any fiscal year of the Company; (v) the payment of
regularly scheduled semi-annual dividends in respect of the Seller Preferred
Stock in an aggregate amount not to exceed $1.4 million in any one year; (vi)

manner and in such amounts as provided in the Acquisition Agreements as in
effect on the Issue Date and described in the Offering Memorandum, in an
aggregate amount not to exceed $16.2 million; provided, however, that the
Company's Consolidated Fixed Charge Coverage Ratio at such time is at least 3.25
to 1; and (xii) the payment of amounts constituting post-closing adjustments to
the former stockholders of the founding companies in respect of (A) working
capital adjustments for which the Company received assets of comparable value

the Acquisition Agreements as in effect on the Issue Date. Any payments made

taken into account in calculating the amount of Restricted Payments made from
and after the Issue Date.

         In computing Consolidated Net Income of the Company under clause (C)(1)
of the first paragraph of this Section 10.9, (1) the Company shall use audited
financial statements for the portions of the relevant period for which audited
financial statements are available on the date of determination and unaudited
financial statements and other current financial data based on the books and
records of the Company for the remaining portion of such period and (2) the
Company shall be permitted to rely in good faith on the financial statements and
other financial data derived from the books and records of the Company that are
available on the date of determination. If the Company makes a Restricted
Payment which, at the time of the making of such Restricted Payment would in the
good faith determination of the Company be permitted under the requirements of
this Indenture, such Restricted Payment shall be deemed to have been made in
compliance with this Indenture notwithstanding any subsequent adjustments made
in good faith to the Company's financial statements affecting Consolidated Net
Income of the Company for any period.

SECTION 10.10.      Limitation on Issuances and Sales of Restricted Subsidiary
                    Stock.

         The Company (i) will not permit any Restricted Subsidiary to issue any
Capital Stock (other than to the Company or a Restricted Subsidiary) and (ii)
will not permit any Person (other than the Company and/or one or more Restricted
Subsidiaries) to own any Capital Stock of any Restricted





                                      -67-
<PAGE>   75

Subsidiary; provided, however, that this Section 10.10 shall not prohibit (1)
the issuance and sale of all, but not less than all, of the issued and
outstanding Capital Stock of any Restricted Subsidiary owned by the Company or
any of its Restricted Subsidiaries in compliance with the other provisions of
this Indenture, or (2) the ownership by directors of directors' qualifying
shares or the ownership by foreign nationals of Capital Stock of any Restricted
Subsidiary, to the extent mandated by applicable law.

SECTION 10.11.      Limitation on Transactions with Affiliates.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, enter into any transaction or series of
related transactions (including, without limitation, the sale, transfer,
disposition, purchase, exchange or lease of assets, property or services) with,
or for the benefit of, any of its Affiliates, except (a) on terms that are no
less favorable to the Company or such Restricted Subsidiary, as the case may be,
than those which could have been obtained at the time in a comparable
transaction or series of related transactions from Persons who are not
Affiliates of the Company, (b) with respect to a transaction or series of
related transactions involving aggregate payments or value equal to or greater
than $5.0 million, the Company shall have delivered an Officer's Certificate to
the Trustee certifying that such transaction or transactions comply with the
preceding clause (a) and have been approved by the Disinterested Members of the
Board of Directors of the Company; provided, however, that the Company may, if
there are no Disinterested Members of the Board of Directors or at its option,
obtain and deliver to the Trustee the written opinion referred to in clause (c)
below in lieu of such Officers' Certificate, and (c) with respect to a
transaction or series of related transactions involving aggregate payments or
value equal to or greater than $10 million, the Company shall have delivered to
the Trustee the Officers' Certificate referred to in clause (b) which includes a
certification that such transaction or transactions have been approved by a
majority of the Disinterested Members of the Board of Directors of the Company
or, in the event there are no such Disinterested Members of the Board of
Directors, that the Company has obtained a written opinion from an independent
nationally recognized investment banking firm, accounting firm or appraisal
firm, in each case specializing or having a specialty in the type and subject
matter of the transaction or series of transactions at issue, which opinion
shall be to the effect set forth in clause (a) above or shall state that such
transaction or series of related transactions is fair from a financial point of
view to the Company or such Restricted Subsidiary.

         Notwithstanding the foregoing, the restrictions set forth in this
Section 10.11 shall not apply to (i) transactions between or among the Company
and its Restricted Subsidiaries, (ii) customary directors' fees, indemnification
and similar arrangements, consulting fees, employee salaries, bonuses or
employment agreements, compensation or employee benefit arrangements and
incentive arrangements with any officer, director or employee of the Company or
any Restricted Subsidiary entered into in the ordinary course of business, (iii)
any dividends made in compliance with Section 10.9, (iv) loans and advances to

$1,000,000 outstanding at any one time, (v) transactions pursuant to agreements

                                      -68-
<PAGE>   76

entered into in the ordinary course of business on terms that are substantially
similar to those which could have been obtained at the time in a comparable
transaction with non-Affiliates or (viii) any sale or other issuance for cash of
Capital Stock (other than Redeemable Capital Stock) of the Company.

SECTION 10.12.      Limitation on Liens.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Liens of any kind securing Indebtedness upon any of its property or
assets, or any proceeds therefrom, unless the Securities are equally and ratably
secured (except that Liens securing Subordinated Indebtedness shall be expressly
subordinate to Liens securing the Securities to the same extent such
Subordinated Indebtedness is subordinate to the Securities), except for (a)
Liens securing Senior Indebtedness and Guarantor Senior Indebtedness; (b) Liens
securing the Securities; (c) Liens securing Indebtedness which is incurred to
refinance Indebtedness which has been secured by a Lien (other than a Lien in
favor of the Company or a Restricted Subsidiary) permitted under this Indenture
and which has been incurred in accordance with the provisions of this Indenture;
provided, however, that such Liens do not extend to or cover any property or
assets of the Company or any its Restricted Subsidiaries not securing the
Indebtedness so refinanced; and (d) Permitted Liens.

SECTION 10.13.      Change of Control.

         On or before the 30th day after the date of the occurrence of a Change
of Control (the "Change of Control Date"), the Company shall make an Offer to
Purchase (a "Change of Control Offer") and shall purchase, on a Business Day
(the "Change of Control Purchase Date") not more than 60 nor less than 30 days
following the mailing of such Offer to Purchase, all of the then Outstanding
Securities tendered at a purchase price in cash (the "Change of Control Purchase
Price") equal to 101% of the principal amount thereof plus accrued and unpaid
interest, if any, thereon to the Change of Control Purchase Date. The Company
shall be required to purchase all Securities tendered into the Change of Control
Offer and not withdrawn. The Change of Control Offer will be required to remain
open for at least 20 Business Days.

         On the Change of Control Purchase Date, the Company shall (i) accept
for payment Securities or portions thereof (not less than $1,000 principal
amount and integral multiples thereof) tendered pursuant to the Change of
Control Offer, (ii) deposit with the Paying Agent money, in immediately
available funds, sufficient to pay the purchase price of all Securities or
portions thereof so tendered and accepted and (iii) deliver to the Trustee the
Securities so accepted together with an Officer's Certificate setting forth the
Securities or portions thereof tendered to and accepted for payment by the
Company. The Paying Agent shall promptly mail or deliver to the Holders of
Securities so accepted payment in an amount equal to the purchase price, and the
Trustee shall promptly authenticate and make available for delivery to such
Holders a new Security of like tenor equal in principal amount to any
unpurchased portion of the Security surrendered. Any Securities not so accepted
shall be promptly mailed or delivered by the Company to the Holder thereof. The
Company shall publicly announce the results of the Change of Control Offer not
later than the third Business Day following the Change of Control Purchase Date.



                                      -69-
<PAGE>   77

         The Company shall not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer at
the same purchase price, at the same time and otherwise in compliance with the
requirements applicable to a Change of Control Offer made by the Company and
purchases all Securities validly tendered and not withdrawn under such Change of
Control Offer.

         In addition, the Company shall not be required to make a Change of
Control Offer, as provided herein, if, in connection with or in contemplation of
any Change of Control, it has made an Offer to Purchase (an "Alternative Offer")
any and all Securities validly tendered at a cash price equal to or higher than
the Change of Control Purchase Price and has purchased all Securities properly
tendered in accordance with the terms of such Alternative Offer. The Company
shall comply with Rule 14e-1 under the Exchange Act and any other securities
laws and regulations thereunder, to the extent such laws or regulations are
applicable, in the event that a Change of Control occurs and the Company is
required to purchase Securities as described above, and any violation of the
provisions of this Indenture relating to such Offer to Purchase occurring as a
result of such compliance shall not be deemed a Default or an Event of Default.

SECTION 10.14.      Disposition of Proceeds of Asset Sales.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any Asset Sale unless (a) the Company or such Restricted
Subsidiary, as the case may be, receives consideration at the time of such Asset
Sale at least equal to the Fair Market Value of the shares or assets sold or
otherwise disposed of and (b) at least 75% of the consideration in such Asset
Sale, plus all other Asset Sales since the Issue Date on a cumulative basis,
consists of cash or Cash Equivalents; provided, however, that the amount of any
Indebtedness (as shown on the most recent balance sheet of the Company or such
Restricted Subsidiary) of the Company or such Restricted Subsidiary that is
assumed by the transferee of such assets as a result of which the Company and
its Restricted Subsidiaries are no longer liable thereon, and any securities,
notes or other obligations received by the Company or such Restricted Subsidiary
from such transferee that are converted within 60 days into cash or Cash
Equivalents (to the extent of the cash or Cash Equivalents received) shall be
deemed to be cash for the purposes of this provision. To the extent that the Net
Cash Proceeds, or portion thereof, of any Asset Sale are not applied to repay,
and permanently reduce the commitments under Senior Indebtedness or Guarantor
Senior Indebtedness in accordance with the terms thereof, the Company or such
Restricted Subsidiary, as the case may be, may apply the Net Cash Proceeds, or
portion thereof, from such Asset Sale, within 360 days of such Asset Sale, to an
investment in properties and assets that replace the properties and assets that
were the subject of such Asset Sale or in properties and assets that (as
determined in good faith by the Board of Directors of the Company or the
Restricted Subsidiary, as the case may be) are used or useful in the business of
the Company and its Restricted Subsidiaries conducted at such time or in
businesses reasonably related thereto or in Capital Stock of a Person, the
principal portion of whose assets consist of such property or assets
("Replacement Assets"). Any Net Cash Proceeds from any Asset Sale that are
neither used to repay, and permanently reduce the commitments under, Senior
Indebtedness or Guarantor Senior Indebtedness in accordance with the terms
thereof nor invested in Replacement Assets within such 360-day period will
constitute "Excess Proceeds" subject to disposition as provided below; provided,
however, that any Net Cash Proceeds from any Asset Sale which are used to repay
Senior Indebtedness or Guarantor Senior





                                      -70-
<PAGE>   78

Indebtedness but are subsequently invested in Replacement Assets within such
360-day period will not constitute "Excess Proceeds."

         When the aggregate amount of Excess Proceeds equals or exceeds $10
million, the Company shall make an Offer to Purchase, from all Holders of the
Securities and any then outstanding Pari Passu Indebtedness required to be
repurchased or repaid on a permanent basis in connection with an Asset Sale, an
aggregate principal amount of Securities and any then outstanding Pari Passu
Indebtedness equal to such Excess Proceeds as follows:

                  (i) (A) The Company shall make an Offer to Purchase (an "Asset
          Sale Offer") from all Holders of the Securities the maximum principal
          amount (expressed as a multiple of $1,000) of Securities that may be
          purchased out of an amount (the "Asset Sale Offer Amount") equal to
          the product of such Excess Proceeds, multiplied by a fraction, the
          numerator of which is the outstanding principal amount of the
          Securities and the denominator of which is the sum of the outstanding
          principal amount of the Securities and such Pari Passu Indebtedness,
          if any (subject to proration in the event such amount is less than the
          aggregate Offered Price (as defined below) of all Securities
          tendered), and (B) to the extent required by such Pari Passu
          Indebtedness and provided there is a permanent reduction in the
          principal amount of such Pari Passu Indebtedness, the Company shall
          make an Offer to Purchase Pari Passu Indebtedness (a "Pari Passu
          Offer") in an amount (the "Pari Passu Indebtedness Amount") equal to
          the excess of the Excess Proceeds over the Asset Sale Offer Amount;

                 (ii) The offer price for the Securities shall be payable in
          cash in an amount equal to 100% of the principal amount of the
          Securities tendered pursuant to an Asset Sale Offer, plus accrued and
          unpaid interest, if any, to the date such Asset Sale Offer is
          consummated (the "Offered Price"), in accordance with the procedures
          set forth in this Indenture. To the extent that the aggregate Offered
          Price of the Securities tendered pursuant to an Asset Sale Offer is
          less than the Asset Sale Offer Amount relating thereto or the
          aggregate amount of the Pari Passu Indebtedness that is purchased or
          repaid pursuant to the Pari Passu Offer is less than the Pari Passu
          Indebtedness Amount (such shortfall constituting an "Asset Sale
          Deficiency"), the Company may use such Asset Sale Deficiency for
          general corporate purposes, subject to the limitations in Section
          10.9; and

                (iii) If the aggregate Offered Price of Securities validly
          tendered and not withdrawn by Holders thereof exceeds the Asset Sale
          Offer Amount, Securities to be purchased will be selected on a pro
          rata basis. Upon completion of such Asset Sale Offer and Pari Passu
          Offer, the amount of Excess Proceeds shall be reset to zero.

         On the Asset Sale Offer Purchase Date, the Company shall (i) accept for
payment (subject to proration as described in the Offer to Purchase) Securities
or portions thereof validly tendered pursuant to the Asset Sale Offer,
respectively, (ii) deposit with the Paying Agent money, in immediately available
funds, sufficient to pay the purchase price of all such Securities or portions
thereof so tendered and accepted and (iii) deliver to the Trustee the Securities
so accepted together with an Officer's Certificate setting forth the Securities
or portions thereof tendered to and accepted for payment by the Company. The
Paying Agent shall promptly mail or deliver to the Holders of Securities so





                                      -71-
<PAGE>   79

accepted payment in an amount equal to the purchase price, and the Trustee shall
promptly authenticate and make available for delivery to such Holders a new
Security of like tenor equal in principal amount to any unpurchased portion of
the Security surrendered. Any Securities not so accepted shall be promptly
mailed or delivered by the Company to the Holder thereof. The Company shall
publicly announce the results of the Asset Sale Offer and Pari Passu Offer not
later than the third Business Day following the Asset Sale Offer Purchase Date.

         Whenever the aggregate amount of Excess Proceeds received by the
Company and its Restricted Subsidiaries exceeds $10 million, such Excess
Proceeds shall, prior to the purchase of Notes, be set aside by the Company or
such Restricted Subsidiary, as the case may be, in a separate account pending
(i) deposit with the Paying Agent of the amount required to purchase the
Securities tendered in an Asset Sale Offer or (ii) delivery by the Company of
the Offered Price to the Holders of the Securities validly tendered and not
withdrawn pursuant to an Asset Sale Offer. Such Excess Proceeds may be invested
in Cash Equivalents, as directed by the Company, having a maturity date which is
not later than the earliest possible date for purchase of Securities pursuant to
the Asset Sale Offer. The Company will be entitled to any interest or dividends
accrued, earned or paid on such Cash Equivalents.

         The Company shall comply with Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder, to the extent such laws and
regulations are applicable, in the event that an Asset Sale occurs and the
Company is required to purchase Securities as described above, and any violation
of the provisions of this Indenture relating to such Offer to Purchase occurring
as a result of such compliance shall not be deemed a Default or an Event of
Default.

SECTION 10.15.      Limitation on Dividends and Other Payment Restrictions
                    Affecting Restricted Subsidiaries.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to (a) pay dividends, in cash or otherwise,
or make any other distributions on or in respect of its Capital Stock to the
Company or any other Restricted Subsidiary, (b) pay any Indebtedness owed to the
Company or any other Restricted Subsidiary, (c) make loans or advances to the
Company or any other Restricted Subsidiary, (d) transfer any of its properties
or assets to the Company or any other Restricted Subsidiary or (e) guarantee any
Indebtedness of the Company or any other Restricted Subsidiary, except for such
encumbrances or restrictions existing under or by reason of (i) applicable law
or any applicable rule, regulation or order, (ii) customary non-assignment
provisions of any contract or any lease governing a leasehold interest of the
Company or any Restricted Subsidiary, (iii) customary restrictions on transfers
of property subject to a Lien permitted under this Indenture (including purchase
money Liens permitted under this Indenture), (iv) any agreement or other
instrument of a Person acquired by the Company or any Restricted Subsidiary in
existence at the time of such acquisition (but not created in contemplation
thereof), which encumbrance or restriction is not applicable to any Person, or
the properties or assets of any Person, other than the Person, or the property
or assets of the Person, so acquired, (v) an agreement entered into for the sale
or disposition of Capital Stock or assets of a Restricted Subsidiary or an
agreement entered into for the sale of specified assets (in either case, so long
as such





                                      -72-
<PAGE>   80

encumbrance or restriction, by its terms, terminates on the earlier of the
termination of such agreement or the consummation of such agreement and so long
as such restriction applies only to the Capital Stock or assets to be sold),
(vi) any agreement in effect on the Issue Date (including, without limitation,
the Credit Facility), (vii) this Indenture and the Guarantees, and (viii) any
agreement that amends, extends, refinances, renews or replaces any agreement
described in the foregoing clauses; provided, however, that the terms and
conditions of any such agreement are not materially less favorable to the
Holders of the Securities with respect to such encumbrances or restrictions than
those under or pursuant to the agreement amended, extended, refinanced, renewed
or replaced.

SECTION 10.16.      Limitation on Issuance of Subordinated Indebtedness.

         The Company will not, and will not permit any Guarantor to, directly or
indirectly, incur any Indebtedness (including Acquired Indebtedness) that is
expressly subordinate or junior in right of payment to any Indebtedness of the
Company or such Guarantor and senior in right of payment to the Securities or
the Guaranty of such Guarantor, as the case may be.

SECTION 10.17.      Additional Subsidiary Guarantees.

         If the Company or any of its Restricted Subsidiaries acquires, creates
or designates another Restricted Subsidiary organized under the laws of the
United States or any possession or territory thereof, any State of the United
States or the District of Columbia, then such newly acquired, created or
designated Restricted Subsidiary shall, within 30 days after the date of its
acquisition, creation or designation, whichever is later, execute and deliver to
the Trustee a supplemental indenture in substantially the form set forth in
Exhibit C, pursuant to which such Subsidiary shall become a Guarantor of the
Securities in the manner set forth in Article XIII; provided, however, that such
Restricted Subsidiary shall not be obligated to become a Guarantor in the manner
set forth above if such Restricted Subsidiary is not, either individually or
when considered in the aggregate with all other Restricted Subsidiaries that are
not Guarantors, a Significant Subsidiary. Thereafter, such Restricted Subsidiary
shall be a Guarantor for all purposes of this Indenture. In addition to the
foregoing, the Company shall cause any Restricted Subsidiary that is not a
Guarantor to become a Guarantor in the manner provided above within 30 days of
such time as it becomes, either individually or when considered in the aggregate
with all other Restricted Subsidiaries that are not Guarantors, a Significant
Subsidiary. The Company at its option may also cause any other Restricted
Subsidiary to become a Guarantor in the manner provided in this Section.

SECTION 10.18.      Limitations on Designation of Unrestricted Subsidiaries.

         (a) The Company may designate after the Issue Date any Restricted
Subsidiary as an "Unrestricted Subsidiary" under this Indenture (a
"Designation") only if:

                  (i) no Default shall have occurred and be continuing at the
         time of or after giving effect to such Designation;

                  (ii) the Company would be permitted to make an Investment
         (other than a Permitted Investment covered by clause (x) of the
         definition thereof) at the time of such Designation (assuming the
         effectiveness of such Designation) pursuant to the first paragraph of






                                      -73-
<PAGE>   81

         Section 10.9 in an amount (the "Designation Amount") equal to the Fair
         Market Value of the Company's interest in such Subsidiary on such date;
         and

                  (iii) the Company would be permitted under this Indenture to
         incur $1.00 of additional Indebtedness (other than Permitted
         Indebtedness) pursuant to Section 10.8 at the time of such Designation
         (assuming the effectiveness of such Designation).

         In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to Section
10.9 for all purposes of this Indenture in the Designation Amount.

         The Company shall not, and shall not cause or permit any Restricted
Subsidiary to, at any time (x) provide credit support for or subject any of its
property or assets (other than the Capital Stock of any Unrestricted Subsidiary)
to the satisfaction of, any Indebtedness of any Unrestricted Subsidiary
(including any undertaking, agreement or instrument evidencing such
Indebtedness), (y) be directly or indirectly liable for any Indebtedness of any
Unrestricted Subsidiary or (z) be directly or indirectly liable for any
Indebtedness which provides that the holder thereof may (upon notice, lapse of
time or both) declare a default thereon or cause the payment thereof to be
accelerated or payable prior to its final Stated Maturity upon the occurrence of
a default with respect to any Indebtedness of any Unrestricted Subsidiary
(including any right to take enforcement action against such Unrestricted
Subsidiary). The Designation of any Subsidiary as an Unrestricted Subsidiary
shall automatically be deemed to include the Designation of all Subsidiaries of
such Subsidiary as Unrestricted Subsidiaries.

         (b) The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:

                  (i) no Default shall have occurred and be continuing at the
         time of and after giving effect to such Revocation, and

                  (ii) all Liens and Indebtedness of such Unrestricted
         Subsidiary outstanding immediately following such Revocation would, if
         incurred at such time, have been permitted to be incurred under this
         Indenture.

         (c) All Designations and Revocations must be evidenced by Board
Resolutions of the Company delivered to the Trustee certifying compliance with
the foregoing provisions.

SECTION 10.19.      Provision of Financial Information.

         For so long as the Securities are outstanding, whether or not the
Company is subject to Section 13(a) or 15(d) of the Exchange Act, or any
successor provision thereto, the Company shall file with the Commission (if
permitted by Commission practice and applicable law and regulations) the annual
reports, quarterly reports and other documents which the Company would have been
required to file with the Commission pursuant to such Section 13(a) or 15(d) or
any successor provision thereto if the Company were so subject, such documents
to be filed with the Commission on or prior to the respective dates (the
"Required Filing Dates") by which the Company would have been required so to
file such documents if the Company were so subject. The Company shall also in
any





                                      -74-
<PAGE>   82

event within 15 days after each Required Filing Date (whether or not permitted
or required to be filed with the Commission) file with the Trustee, copies of
the annual reports, quarterly reports and other documents which the Company
would be required to file with the Commission if the Securities were then
registered under the Exchange Act and to make such information available to
Holders of Securities upon request. In addition, if the Company is not subject
to the reporting requirements of the Exchange Act, for so long as any Securities
remain outstanding, the Company will furnish to the Holders of Securities and
prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act.

SECTION 10.20.      Statement by Officers as to Default; Compliance
                    Certificates.

         (a) The Company shall deliver to the Trustee, prior to January 1 in
each year commencing January 1, 2000, an Officer's Certificate, stating whether
or not to the best knowledge of the signers thereof the Company is in default in
the performance and observance of any of the terms, provisions and conditions of
this Indenture (without regard to any period of grace or requirement of notice
provided hereunder), and if the Company shall be in default, specifying all such
defaults and the nature and status thereof of which he may have knowledge.

         (b) The Company shall deliver to the Trustee, as soon as possible and
in any event within five business days after the Company becomes aware of the
occurrence of a Default or an Event of Default, an Officer's Certificate setting
forth the details of such Default or Event of Default, and the action which the
Company proposes to take with respect thereto.


                                   ARTICLE XI

                            REDEMPTION OF SECURITIES


SECTION 11.1.       Right of Redemption.

         The Securities may be redeemed at the election of the Company, in the
amounts, at the times, at the Redemption Prices (together with any applicable
accrued and unpaid interest to the Redemption Date), and subject to the
conditions specified in the form of Security and hereinafter set forth.

SECTION 11.2.       Applicability of Article.

         Redemption of Securities at the election of the Company, as permitted
by this Indenture and the provisions of the Securities, shall be made in
accordance with such provisions and this Article.

SECTION 11.3.       Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities pursuant to
Section 11.1 shall be evidenced by a Board Resolution. In the event of any
redemption at the election of the Company pursuant to Section 11.1, the Company
shall notify the Trustee, in case of a redemption of less than all the
Securities, at least 60 days, and in the case of a redemption of all the
Securities, at least 40 days, prior





                                      -75-
<PAGE>   83

to the Redemption Date fixed by the Company (in each case, unless a shorter
notice shall be satisfactory to the Trustee) of such Redemption Date and of the
principal amount of Securities to be redeemed.

SECTION 11.4.       Selection by Trustee of Securities To Be Redeemed.

         In the event that less than all of the Securities are to be redeemed at
any time, selection of such Securities for redemption will be made by the
Trustee in compliance with the requirements of the principal national securities
exchange, if any, on which the Securities are listed or, if the Securities are
not then listed on a national securities exchange, on a pro rata basis, by lot
or by such method as the Trustee shall deem fair and appropriate (subject to the
rules of the Depository); provided, however, that Securities shall only be
redeemable in amounts of $1,000 or an integral multiple of $1,000.

         The Trustee shall promptly notify the Company and each Security
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected for partial redemption, the principal amount thereof
to be redeemed.

         For all purposes of this Indenture and of the Securities, unless the
context otherwise requires, all provisions relating to the redemption of
Securities shall relate, in the case of any Securities redeemed or to be
redeemed only in part, to the portion of the principal amount of such Securities
which has been or is to be redeemed.

SECTION 11.5.       Notice of Redemption.

         Notice of redemption shall be given by first class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall identify the Securities to be redeemed
(including, if used, CUSIP or CINS numbers) and shall state:

                  (i) the Redemption Date,

                  (ii) the Redemption Price,

                  (iii) if less than all the Outstanding Securities are to be
         redeemed, the identification (and, in the case of partial redemption,
         the principal amounts) of the particular Securities to be redeemed,

                  (iv) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security to be redeemed and that
         interest thereon will cease to accrue on and after such Redemption
         Date,

                  (v) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price, and




                                      -76-
<PAGE>   84

                 (vi) if the redemption is being made pursuant to the provisions
          of the Securities regarding a Public Equity Offering, a brief
          description of the transaction or transactions giving rise to such
          redemption, the nature and amount of Capital Stock sold by the Company
          thereto in such transaction or transactions, the aggregate purchase
          price thereof and the net cash proceeds therefrom available for such
          redemption, the date or dates on which such transaction or
          transactions were completed and the percentage of the aggregate
          principal amount of Outstanding Securities being redeemed.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.

SECTION 11.6.       Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 10.3) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) any applicable accrued interest on, all
the Securities which are to be redeemed on that date.

SECTION 11.7.       Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and any applicable
accrued interest) such Securities shall not bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with any applicable
accrued and unpaid interest to the Redemption Date; provided, however, that
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
predecessor Notes, registered as such at the close of business on the relevant
record dates according to their terms and the provisions of Section 3.7.

         If any Security called for redemption in accordance with the election
of the Company made pursuant to Section 11.1 shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate provided by the Security.

SECTION 11.8.       Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at an office or agency of the Company designated for that purpose pursuant to
Section 10.2 (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing), and the Company shall execute, and the Trustee shall authenticate
and deliver to the Holder of such Security without service charge, a new
Security or Securities, of any authorized denomination




                                      -77-
<PAGE>   85

as requested by such Holder, in aggregate principal amount at Stated Maturity
equal to and in exchange for the unredeemed portion of the principal amount at
Stated Maturity of the Security so surrendered.


                                   ARTICLE XII

                       DEFEASANCE AND COVENANT DEFEASANCE


SECTION 12.1.       Company's Option To Effect Defeasance or Covenant
                    Defeasance.

         The Company may elect, at its option at any time, to have Section 12.2
or Section 12.3 applied to the Outstanding Securities (as a whole and not in
part) upon compliance with the conditions set forth below in this Article. Any
such election shall be evidenced by a Board Resolution.

SECTION 12.2.       Defeasance and Discharge.

         Upon the Company's exercise of its option to have this Section applied
to the Outstanding Securities (as a whole and not in part), the Company shall be
deemed to have been discharged from its obligations with respect to such
Securities as provided in this Section on and after the date the conditions set
forth in Section 12.4 are satisfied (hereinafter called "Defeasance"). For this
purpose, such Defeasance means that the Company shall be deemed to have paid and
discharged the entire Indebtedness represented by such Securities and to have
satisfied all its other obligations under such Securities and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging the same), subject to
the following which shall survive until otherwise terminated or discharged
hereunder: (1) the rights of Holders of Outstanding Securities to receive,
solely from the trust fund described in Section 12.4 and as more fully set forth
in such Section, payments in respect of the principal of, premium, if any, and
interest on such Securities when payments are due, (2) the Company's obligations
with respect to such Securities under Sections 3.4, 3.5, 3.6, 10.2 and 10.3, (3)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(4) this Article. Subject to compliance with this Article, the Company may
exercise its option to have this Section applied to the Outstanding Securities
(as a whole and not in part) notwithstanding the prior exercise of its option to
have Section 12.3 applied to such Securities.

SECTION 12.3.       Covenant Defeasance.

         Upon the Company's exercise of its option to have this Section applied
to the Outstanding Securities (as a whole and not in part), (i) the Company and
the Guarantors shall be released from their obligations under Section 8.1(A)(3),
Sections 10.5 through 10.19, inclusive, and any covenant provided pursuant to
Section 9.1(ii), (ii) the occurrence of any event specified in Sections 5.1(3)
and 5.1(4) (with respect to Section 8.1(A)(3) and any of Sections 10.5 through
10.19, inclusive, and any such covenants provided pursuant to Section 9.1(ii)),
shall be deemed not to be or result in an Event of Default, in each case with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 12.4 are satisfied (hereinafter called "Covenant
Defeasance").




                                      -78-
<PAGE>   86

For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section (to the extent so specified in the case of Sections 5.1(3) or 5.1(4)),
whether directly or indirectly, by reason of any reference elsewhere herein to
any such Section or by reason of any reference in any such Section to any other
provision herein or in any other document, but the remainder of this Indenture
and such Securities shall be unaffected thereby.

SECTION 12.4.       Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions to the application of Section
12.2 or Section 12.3 to the Outstanding Securities:

                  (1) The Company or any Guarantor shall irrevocably have
         deposited or caused to be deposited with the Trustee (or another
         trustee which satisfies the requirements contemplated by Section 6.9
         and agrees to comply with the provisions of this Article applicable to
         it) as trust funds in trust for the purpose of making the following
         payments, specifically pledged as security for, and dedicated solely
         to, the benefits of the Holders of such Securities, (A) money in an
         amount, or (B) U.S. Government Obligations which through the scheduled
         payment of principal and interest in respect thereof in accordance with
         their terms will provide, not later than one day before the due date of
         any payment, money in an amount, or (C) a combination thereof, in each
         case sufficient, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the Trustee (or any such other qualifying trustee) to pay
         and discharge, the principal of, premium, if any, and any installment
         of interest on such Securities on the respective Stated Maturities
         thereof, in accordance with the terms of this Indenture and such
         Securities. As used herein, "U.S. Government Obligation" means (x) any
         security which is (i) a direct obligation of the United States of
         America for the payment of which the full faith and credit of the
         United States of America is pledged or (ii) an obligation of a Person
         controlled or supervised by and acting as an agency or instrumentality
         of the United States of America the payment of which is unconditionally
         guaranteed as a full faith and credit obligation by the United States
         of America, which, in either case (i) or (ii), is not callable or
         redeemable at the option of the issuer thereof, and (y) any depositary
         receipt issued by a bank (as defined in Section 3(a)(2) of the
         Securities Act) as custodian with respect to any U.S. Government
         Obligation which is specified in clause (x) above and held by such bank
         for the account of the holder of such depositary receipt, or with
         respect to any specific payment of principal of or interest on any U.S.
         Government Obligation which is so specified and held, provided (except
         as required by law) such custodian is not authorized to make any
         deduction from the amount payable to the holder of such depositary
         receipt from any amount received by the custodian in respect of the
         U.S. Government Obligation or the specific payment of principal or
         interest evidenced by such depositary receipt.

                  (2) In the event of an election to have Section 12.2 apply to
         the Outstanding Securities, the Company shall have delivered to the
         Trustee an Opinion of Counsel stating that (A) the Company has received
         from, or there has been published by, the Internal Revenue Service a
         ruling or (B) since the date of this Indenture, there has been a change
         in the




                                      -79-
<PAGE>   87

         applicable Federal income tax law, in either case to the effect that,
         and based thereon such opinion shall confirm that, the Holders of such
         Securities will not recognize gain or loss for Federal income tax
         purposes as a result of the deposit, Defeasance and discharge to be
         effected with respect to such Securities and will be subject to Federal
         income tax on the same amount, in the same manner and at the same times
         as would be the case if such deposit, Defeasance and discharge were not
         to occur.

                  (3) In the event of an election to have Section 12.3 apply to
         the Outstanding Securities, the Company shall have delivered to the
         Trustee an Opinion of Counsel to the effect that the Holders of such
         Securities will not recognize gain or loss for Federal income tax
         purposes as a result of the deposit and Covenant Defeasance to be
         effected with respect to such Securities and will be subject to Federal
         income tax on the same amount, in the same manner and at the same times
         as would be the case if such deposit and Covenant Defeasance were not
         to occur.

                  (4) No Default or Event of Default with respect to the
         Outstanding Securities shall have occurred and be continuing at the
         time of such deposit (excluding a Default or Event of Default due to a
         breach of Section 10.8 which arises solely due to the borrowing of
         funds entirely and immediately applied to such deposit).

                  (5) Such Defeasance or Covenant Defeasance shall not cause the
         Trustee to have a conflicting interest with respect to any Securities
         of the Company or any Guarantor.

                  (6) Such Defeasance or Covenant Defeasance shall not result in
         a breach or violation of, or constitute a default under, any other
         agreement or instrument to which the Company is a party or by which it
         is bound.

                  (7) The Company shall have delivered to the Trustee an Opinion
         of Counsel (which opinion may be subject to customary assumptions and
         exceptions) to the effect that after the 91st day following the
         deposit, the trust funds will not be subject to the effect of any
         applicable bankruptcy, insolvency, reorganization or similar laws
         affecting creditors' rights generally.

                  (8) The Company shall have delivered to the Trustee an
         Officer's Certificate stating that the deposit was not made by the
         Company with the intent of preferring the Holders of the Securities
         over the other creditors of the Company or any Guarantor with the
         intent of defeating, hindering, delaying or defrauding creditors of the
         Company or any Guarantor or others.

                  (9) No event or condition shall exist that would prevent the
         Company from making payments of the principal of, premium, if any, and
         interest on the Securities on the date of such deposit or at any time
         ending on the 91st day after the date of such deposit.

                  (10) The Company shall have delivered to the Trustee an
         Officer's Certificate and an Opinion of Counsel, each stating that all
         conditions precedent under this Indenture to either Defeasance or
         Covenant Defeasance, as the case may be, have been complied with.

SECTION 12.5.       Deposited Money and U.S. Government Obligations To Be Held
                    in Trust; Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 10.3, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this
Section and Section 12.6, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 12.4 in respect of the
Outstanding Securities shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any such Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Securities, of all sums due and to become due thereon in respect of
principal and any premium and interest, but money so held in trust need not be
segregated from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 12.4 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 12.4
which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be,
with respect to the Outstanding Securities.

SECTION 12.6.       Reinstatement.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining,
or otherwise prohibiting such application, then the obligations under this
Indenture, such Securities and the Guarantees from which the Company and the
Guarantors have been discharged or released pursuant to Section 12.2 or 12.3
shall be revived and reinstated as though no deposit had occurred pursuant to
this Article with respect to such Securities, until such time as the Trustee or
Paying Agent is permitted to apply all money held in trust pursuant to Section
12.5 with respect to such Securities in accordance with this Article; provided,
however, that if the Company makes any payment of principal of or any premium or
interest on any such Security following such reinstatement of its obligations,
the Company shall be subrogated to the rights (if any) of the Holders of such
Securities to receive such payment from the money so held in trust.

                                  ARTICLE XIII

                                    GUARANTY


SECTION 13.1.       Guaranty.

         Each Guarantor hereby unconditionally and irrevocably guarantees on a
senior subordinated basis, jointly and severally, to each Holder and to the
Trustee and its successors and assigns (a) the full and prompt payment (within
applicable grace periods) of principal of and interest on the Securities when
due, whether at maturity, by acceleration, by redemption or otherwise, and all
other monetary obligations of the Company under this Indenture and the
Securities and (b) the full and prompt performance within applicable grace
periods of all other obligations of the Company under this Indenture and the
Securities (all the foregoing being hereinafter collectively called the
"Guaranty Obligations"). Each Guarantor further agrees that the Guaranty
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from such Guarantor, and that such Guarantor will remain bound
under this Article XIII notwithstanding any extension or renewal of any Guaranty
Obligation.

         To the extent that any Guarantor shall be required to pay any amounts
on account of the Securities pursuant to a Guaranty in excess of an amount
calculated as the product of (i) the aggregate amount payable by the Guarantors
on account of the Securities pursuant to the Guarantees times (ii) the
proportion (expressed as a fraction) that such Guarantor's net assets
(determined in accordance with GAAP) at the date enforcement of the Guarantees
is sought bears to the aggregate net assets (determined in accordance with GAAP)
of all Guarantors at such date, then such Guarantor shall be reimbursed by the
other Guarantors for the amount of such excess, pro rata, based upon the
respective net assets (determined in accordance with GAAP) of such other
Guarantors at the date enforcement of the Guarantees is sought. This paragraph
is intended only to define the relative rights of Guarantors as among
themselves, and nothing set forth in this paragraph is intended to or shall
impair the joint and several obligations of the Guarantors under their
respective Guarantees.

         The Guarantors shall have the right to seek contribution from any
non-paying Guarantor so long as the exercise of such right does not impair the
rights of the Holders under any Guaranty.

         Each Guarantor waives presentation to, demand of payment from and
protest to the Company of any of the Guaranty Obligations and also waives notice
of protest for nonpayment. Each Guarantor waives notice of any default under the
Securities or the Guaranty Obligations. The obligations of each Guarantor
hereunder shall not be affected by (a) the failure of any Holder or the Trustee
to assert any claim or demand or to enforce any right or remedy against the
Company or any other Person under this Indenture, the Securities or any other
agreement or otherwise; (b) any extension or renewal of any thereof; (c) any
rescission, waiver, amendment or modification of any of the terms or provisions
of this Indenture, the Securities or any other agreement; (d) the release of any
Security held by any Holder or the Trustee for the Guaranty Obligations or any
of them; (e) the failure of any Holder or Trustee to exercise any right or
remedy against any other guarantor of the Guaranty Obligations; or (f) any
change in the ownership of any Guarantor (subject to Section 13.5(b)).




                                      -82-
<PAGE>   90

         Each Guarantor further agrees that its Guaranty herein constitutes a
guaranty of payment, performance and compliance when due (and not a guaranty of
collection) and waives any right to require that any resort be had by any Holder
or the Trustee to any Security held for payment of the Guaranty Obligations.

         To the fullest extent permitted by law, the obligations of each
Guarantor hereunder shall not be subject to any reduction, limitation,
impairment or termination for any reason, including any claim of waiver,
release, surrender, alteration or compromise, and shall not be subject to any
defense of setoff, counterclaim, recoupment or termination whatsoever or by
reason of the invalidity, illegality or unenforceability of the Guaranty
Obligations or otherwise. Without limiting the generality of the foregoing, to
the fullest extent permitted by law, the obligations of each Guarantor herein
shall not be discharged or impaired or otherwise affected by the failure of any
Holder or the Trustee to assert any claim or demand or to enforce any remedy
under this Indenture, the Securities or any other agreement, by any waiver or
modification of any thereof, by any default, failure or delay, willful or
otherwise, in the performance of the Guaranty Obligations, or by any other act
or thing or omission or delay to do any other act or thing which may or might in
any manner or to any extent vary the risk of such Guarantor or would otherwise
operate as a discharge of each Guarantor as a matter of law or equity.

         Each Guarantor further agrees that its Guaranty herein shall continue
to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of principal of or interest on any Guaranty Obligation is
rescinded or must otherwise be restored by any Holder or the Trustee upon the
bankruptcy or reorganization of the Company or otherwise.

         In furtherance of the foregoing and not in limitation of any other
right which any Holder or the Trustee has at law or in equity against each
Guarantor by virtue hereof, upon the failure of the Company to pay the principal
of or interest on any Guaranty Obligation when and as the same shall become due,
whether at maturity, by acceleration, by redemption or otherwise (within
applicable grace periods), or to perform or comply with any other Guaranty
Obligation (within applicable grace periods), each Guarantor hereby promises to
and shall, upon receipt of written demand by the Trustee, forthwith pay, or
cause to be paid, in cash, to the Holders or the Trustee an amount equal to the
sum of (i) the unpaid principal amount of such Guaranty Obligations (ii) accrued
and unpaid interest on such Guaranty Obligations (but only to the extent not
prohibited by law) and (iii) all other monetary Guaranty Obligations of the
Company to the Holders and the Trustee.

         Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any Guaranty Obligations
guarantied hereby until payment in full of all Guaranty Obligations. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the Guaranty
Obligations guarantied hereby may be accelerated as provided in Article V for
the purposes of its Guaranty herein, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the Guaranty
Obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such Guaranty Obligations as provided in Article V, such
Guaranty Obligations (whether or not due and payable) shall forthwith become due
and payable by each Guarantor for the purposes of this Section.




                                      -83-
<PAGE>   91

         Each Guarantor also agrees to pay any and all costs and expenses
(including reasonable attorneys' fees and expenses) incurred by the Trustee or
any Holder in enforcing any rights under this Section.

SECTION 13.2.       Limitation on Liability.

         Any term or provision of this Indenture to the contrary
notwithstanding, the obligations of each Guarantor hereunder are limited to the
maximum amount which, after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any collections from or
payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under its Guaranty or pursuant to its
contribution obligations under this Indenture, will result in the obligations of
such Guarantor under this Indenture or its Guaranty not being voidable as a
fraudulent conveyance or fraudulent transfer under federal or state law.

SECTION 13.3.       Execution and Delivery of Guarantees; Supplemental
                    Indentures.

         The Guaranty of each Guarantor shall be conclusively evidenced by the
execution and delivery by such Guarantor of this Indenture. The execution and
delivery of any Restricted Subsidiary of the Company that is required to become
a Guarantor pursuant to Section 10.17 shall be conclusively evidenced by its
execution and delivery of the supplemental indenture referred to therein.

         Each Guarantor hereby agrees that its Guaranty shall remain in full
force and effect notwithstanding any failure to endorse on each Security a
notation of such Guaranty.

         The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantees on behalf of
the Guarantors.

SECTION 13.4.       Guarantors May Consolidate, Etc., on Certain Terms.

         (a) Except as may be provided in Articles VIII and X, nothing contained
in this Indenture or in any of the Securities shall prevent any consolidation or
merger of a Guarantor with or into the Company or another Guarantor or shall
prevent any sale or conveyance of the assets of a Guarantor as an entirety or
substantially as an entirety or the Capital Stock of a Guarantor to the Company
or another Guarantor.

         (b) No Guarantor shall consolidate with or merge with or into (whether
or not such Guarantor is the surviving Person), another Person (other than the
Company or another Guarantor), whether or not affiliated with such Guarantor,
unless, (i) subject to Section 13.5, the Person formed by or surviving any such
consolidation or merger (if other than such Guarantor) assumes all the
obligations of such Guarantor pursuant to a supplemental indenture,
substantially in the form of Exhibit C hereto, under the Securities and this
Indenture; and (ii) immediately after giving effect to such transaction, no
Default or Event of Default exists. In the case of any such consolidation or
merger and upon the assumption by the successor Person by supplemental indenture
of the applicable Guaranty, such successor Person shall succeed to and be
substituted for the Guarantor with the same effect as if it had been named
herein as a Guarantor.

<PAGE>   92

SECTION 13.5.       Release of Guarantors.

         (a) Concurrently with any consolidation or merger of a Guarantor or any
sale or conveyance of all or substantially all of the assets of a Guarantor, in
each case as permitted by the other provisions of this Indenture (including,
without limitation, Sections 10.9, 10.11 and 10.14) and as a result of which
such Guarantor ceases to be a Restricted Subsidiary of the Company, upon
delivery by the Company to the Trustee of an Officer's Certificate to the effect
that such consolidation, merger, sale or conveyance was made in accordance with
this Indenture and an Opinion of Counsel to the effect that such transaction is
permitted by this Indenture (which opinion may be subject to customary
assumptions and limitations), the Trustee shall execute any documents reasonably
required in order to evidence the release of such Guarantor from its obligations
under its Guaranty under this Article XIII. Any Guarantor not released from its
obligations under its Guaranty under this Article XIII shall remain liable for
the full amount of principal of and premium, if any, and interest on the
Securities and for the other obligations of a Guarantor under its Guaranty under
this Article XIII.

         (b) In the event that the Company designates a Guarantor to be an
Unrestricted Subsidiary in accordance with the terms of this Indenture
(including Section 10.18), then such Guarantor shall be released and relieved of
any obligations under its Guaranty.

SECTION 13.6.       Successors and Assigns.

         This Article XIII shall be binding upon each Guarantor and its
successors and assigns and shall inure to the benefit of the successors and
assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges
conferred upon that party in this Indenture and in the Securities shall
automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions of this Indenture.

SECTION 13.7.       No Waiver, etc.

         Neither a failure nor a delay on the part of either the Trustee or the
Holders in exercising any right, power or privilege under this Article XIII
shall operate as a waiver thereof, nor shall a single or partial exercise
thereof preclude any other or further exercise of any right, power or privilege.
The rights, remedies and benefits of the Trustee and the Holders herein
expressly specified are cumulative and not exclusive of any other rights,
remedies or benefits which either may have under this Article XIII at law, in
equity, by statute or otherwise.

SECTION 13.8.       Modification, etc.

         No modification, amendment or waiver of any provision of this Article,
nor the consent to any departure by a Guarantor therefrom, shall in any event be
effective unless the same shall be in writing and signed by the Trustee, and
then such waiver or consent shall be effective only in the specific instance and
for the purpose for which given. No notice to or demand on a Guarantor in any
case shall entitle such Guarantor or any other guarantor to any other or further
notice or demand in the same, similar or other circumstances.

SECTION 13.9.       Subordination of Guarantees.

         The obligations of each Guarantor pursuant to its Guaranty and this
Article XIII shall be (a) junior and subordinated in right of payment to the
prior payment in full in cash of all Guarantor Senior Indebtedness of such
Guarantor and (b) senior in right of payment to all existing and future
Guarantor Subordinated Indebtedness of such Guarantor, in each case on the same
basis as the Securities and the obligations of the Company hereunder are junior
and subordinated to all Senior Indebtedness and senior in right of payment to
all Subordinated Indebtedness. For the purposes of this Section 13.9, Article
XIV shall apply to the obligations of each Guarantor under its Guaranty, this
Article XIII and the other provisions of this Indenture as if references therein
to the Company, the Securities, Senior Indebtedness, Subordinated Indebtedness
and Designated Senior Indebtedness were references to such Guarantor, such
Guarantor's Guaranty, Guarantor Senior Indebtedness, Guarantor Subordinated
Indebtedness and Designated Guarantor Senior Indebtedness, respectively.


                                   ARTICLE XIV

                                  SUBORDINATION


SECTION 14.1.       Securities Subordinate to Senior Indebtedness and Senior
                    to Subordinated Indebtedness.

         The Company covenants and agrees, and each Holder of a Security, by his
acceptance thereof, likewise covenants and agrees that, to the extent and in the
manner hereinafter set forth in this Article XIV, the Indebtedness evidenced by
the Securities is hereby expressly made subordinate in right of payment to the
prior payment in full in cash of all Senior Indebtedness (including Indebtedness
under the Credit Facility) and senior in right of payment to all existing and
future Subordinated Indebtedness of the Company.

SECTION 14.2.       Payment Over of Proceeds upon Dissolution, Etc.

         In the event of (a) any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relating to the Company or its assets, or
(b) any liquidation, dissolution or other winding-up of the Company, whether
voluntary or involuntary, or (c) any assignment for the benefit of creditors or
other marshaling of assets or liabilities of the Company, all Senior
Indebtedness (including, in the case of Designated Senior Indebtedness, any
interest accruing subsequent to the filing of a petition for bankruptcy
(regardless of whether such interest is an allowed claim in the bankruptcy
proceeding)) must be paid in full in cash before any direct or indirect payment
(other than payments from a trust previously created pursuant to Article XII) by
or on behalf of the Company of any kind or character (excluding Permitted Junior
Securities) may be made on account of the principal of, premium, if any, or
interest on, or the purchase, redemption or other acquisition of, the
Securities.




                                      -86-
<PAGE>   94

SECTION 14.3.       No Payment When Designated Senior Indebtedness in Default.

         During the continuance of any default in the payment of principal, or
premium, if any, or interest on any Senior Indebtedness, when the same becomes
due, and after receipt by the Trustee and the Company from representatives of
holders of such Senior Indebtedness of written notice of such default, no direct
or indirect payment (other than payments from trusts previously created pursuant
to Article XII) by or on behalf of the Company of any kind or character
(excluding Permitted Junior Securities) may be made on account of the principal
of, premium, if any, or interest on, or the purchase, redemption or other
acquisition of, the Securities unless and until such default has been cured or
waived or has ceased to exist or such Senior Indebtedness shall have been paid
in full in cash or indefeasibly discharged, after which the Company shall resume
making any and all required payments in respect of the Securities, including any
missed payments.

         In addition, during the continuance of any other default with respect
to any Designated Senior Indebtedness that permits, or would permit with the
passage of time or the giving of notice or both, the maturity thereof to be
accelerated (a "Non-payment Default") and upon the earlier to occur of (a)
receipt by the Trustee and the Company from the representatives of holders of
such Designated Senior Indebtedness of a written notice of such Non-payment
Default or (b) if such Non-payment Default results from the acceleration of the
maturity of the Securities, the date of such acceleration, no direct or indirect
payment (other than payments from trusts previously created pursuant to Article
XII) of any kind or character (excluding Permitted Junior Securities) may be
made by the Company on account of the principal of, premium, if any, or interest
on, or the purchase, redemption, or other acquisition of, the Securities for the
period specified below (the "Payment Blockage Period").

         The Payment Blockage Period shall commence upon the receipt of notice
of a Non-payment Default by the Trustee and the Company from the representatives
of holders of Designated Senior Indebtedness or the date of the acceleration
referred to in clause (b) of the preceding paragraph, as the case may be, and
shall end on the earliest to occur of the following events: (i) 179 days have
elapsed since the receipt of such notice or the date of the acceleration
referred to in clause (b) of the preceding paragraph (provided the maturity of
such Designated Senior Indebtedness shall not theretofore have been
accelerated), (ii) such default is cured or waived or ceases to exist or such
Designated Senior Indebtedness is paid in full in cash or indefeasibly
discharged, or (iii) such Payment Blockage Period shall have been terminated by
written notice to the Company or the Trustee from the representatives of holders
of Designated Senior Indebtedness initiating such Payment Blockage Period, after
which the Company shall promptly resume making any and all required payments in
respect of the Securities, including any missed payments. Only one Payment
Blockage Period with respect to the Securities may be commenced within any 360
consecutive day period. No Non-payment Default with respect to Designated Senior
Indebtedness that existed or was continuing on the date of the commencement of
any Payment Blockage Period with respect to the Designated Senior Indebtedness
initiating such Payment Blockage Period will be, or can be, made the basis for
the commencement of a second Payment Blockage Period, whether or not within a
period of 360 consecutive days, unless such default has been cured or waived for
a period of not less than 90 consecutive days. In no event will a Payment
Blockage Period extend beyond 179 days from the date of the receipt by the
Trustee of the notice or the date of the acceleration initiating such Payment
Blockage Period, and there must




                                      -87-
<PAGE>   95

be a 181 consecutive day period in any 360 day period during which no Payment
Blockage Period is in effect.

SECTION 14.4.       Subrogation to Rights of Holders of Senior Indebtedness.

         Subject to the payment in full in cash of all Senior Indebtedness, the
Holders of the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Indebtedness pursuant to the
provisions of this Article XIV to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of,
premium, if any, and interest on the Securities shall be paid in full. For
purposes of such subrogation, no payments or distributions to the holders of the
Senior Indebtedness of any cash, property or securities to which the Holders of
the Securities or the Trustee would be entitled except for the provisions of
this Article XIV, and no payments over pursuant to the provisions of this
Article XIV to the holders of Senior Indebtedness by Holders of the Securities
or the Trustee, shall, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, be deemed to be a payment
or distribution by the Company to or on account of the Senior Indebtedness.

SECTION 14.5.       Provisions Solely To Define Relative Rights.

         The provisions of this Article XIV are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article XIV or elsewhere in this Indenture or in the
Securities is intended to or shall (a) impair, as among the Company, its
creditors other than holders of Senior Indebtedness and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Securities the principal of, premium, if any and
interest on the Securities as and when the same shall become due and payable in
accordance with their terms; (b) affect the relative rights against the Company
of the Holders of the Securities and creditors of the Company other than the
holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any
Securities from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article XIV of the holders of Senior Indebtedness to receive cash, property and
securities otherwise payable or deliverable to the Trustee or such Holder.

SECTION 14.6.       Trustee To Effectuate Subordination.

         Each Holder of a Security by its acceptance thereof authorizes and
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article XIV and
appoints the Trustee its attorney-in-fact for any and all such purposes.

SECTION 14.7.       No Waiver of Subordination Provisions.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any





                                      -88-
<PAGE>   96

non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article
XIV or the obligations hereunder of the Holders of the Securities to the holders
of Senior Indebtedness, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, Senior Indebtedness, or otherwise amend or supplement in any manner
Senior Indebtedness or any instrument evidencing the same or any agreement under
which Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.

SECTION 14.8.       Notice to Trustee.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article XIV or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee therefor; and,
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 6.1, shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Trustee shall not have received
at its Corporate Trust Office the notice provided for in this Section at least
three Business Days prior to the date upon which by the terms hereof any money
may become payable for any purpose (including, without limitation, the payment
in cash of the principal of, premium, if any or interest on any Security), then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such money and to apply the same to the
purpose for which such money was received and shall not be affected by any
notice to the contrary which may be received by it within three Business Days
prior to such date.

SECTION 14.9.       Reliance on Judicial Order or Certificate of Liquidating
                    Agent.

         Upon any payment or distribution of assets of the Company referred to
in this Article XIV, the Trustee, subject to the provisions of Section 6.1, and
the Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of

other Indebtedness of the Company, the amount thereof or payable thereon, the

SECTION 14.10.      Trustee Not Fiduciary for Holders of Senior Indebtedness.

         The Trustee shall not be deemed to owe any fiduciary duty to the

shall in good faith mistakenly pay over or distribute to Holders of Securities
or to the Company or to any other Person cash, property or securities to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
XIV or otherwise, except in the case of gross negligence or wilful misconduct on

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XIV with respect to any Senior Indebtedness
which may at any time be held by it, to the same extent as any other holder of
Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of
any of its rights as such holder.

         Nothing in this Article XIV shall apply to claims of, or payments to,
the Trustee or its agent or counsel under or pursuant to Section 6.7.

SECTION 14.12.      Article Applicable to Paying Agents.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article XIV shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article XIV in addition to or in place of the Trustee; provided,
however, that Section 14.11 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

         American Plumbing & Mechanical, Inc., a corporation duly organized and
existing under the laws of the State of Delaware (herein called the "Company,"
which term includes any successor Person under the Indenture hereinafter
referred to), for value received, hereby promises to pay to Cede & Co. or
registered assigns, the principal sum of One Hundred Twenty-Five Million Dollars
($125,000,000) on October 15, 2008 and to pay interest thereon from October 15,
1999 or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, semiannually in arrears on April 15 and October 15,
in each year, commencing October 15, 1999 at the rate of 11 5/8% per annum,
until the principal hereof is paid or duly provided for, provided that any
principal and premium, and any such installment of interest, which is overdue
shall bear interest at the rate of 11 5/8% per annum (to the extent that the
payment of such interest shall be legally enforceable), from the dates such
amounts are due until they are paid or duly provided for. The interest so
payable and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in such Indenture, be paid to the Person in whose name this
Security (or one or more predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest, which shall be the April
1 and October 1 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. Any such interest not so punctually paid
or duly provided for will forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in said
Indenture.

         Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose, in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that, at the option of the Company, payment of interest may be made by
check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register (subject to the right of certain holders to
request payment by wire transfer as provided in the Indenture).

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

         This Security is one of a duly authorized issue of Securities of the
Company designated as 11 5/8% Senior Subordinated Notes due 2008, Series A
(herein called the "Initial Securities"), limited in aggregate principal amount
at Stated Maturity to $250,000,000 issued and to be issued under an Indenture,
dated as of May 19, 1999 (herein called the "Indenture," which term shall have
the meaning assigned to it in such instrument), among the Company, the
Guarantors named therein and State Street Bank and Trust Company, as Trustee
(herein called the "Trustee," which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered. The
Securities include the Initial Securities and the Exchange Securities referred
to below, which may be issued in exchange for the Initial Securities pursuant to
the Registration Rights Agreement. The Initial Securities and the Exchange
securities are treated as a single class of securities under the Indenture.

         The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S.C. Sections 7aaa - 77bbbb) (the "TIA"), as in effect on the date of the
Indenture. Notwithstanding anything to the contrary herein, the Securities are
subject to all such terms, and Holders of Securities are referred to the
Indenture and the TIA for a statement of such terms. The Securities are
unsecured senior subordinated obligations of the Company limited to
$250,000,000.

         This Security is redeemable at the option of the Company, in whole or
in part, at any time on or after April 15, 2004, at the Redemption Prices
(expressed as percentages of principal amount) set forth below, plus accrued and
unpaid interest, if any, thereon to the Redemption Date, if redeemed during the
12-month period beginning April 15 of the years indicated below:

         Year                                                        Price
         ----                                                      ----------
<S>                                                                 <C>

</TABLE>

         In addition, at any time, or from time to time, on or prior to April
15, 2002, the Company may, at its option, use the net cash proceeds of one or
more Public Equity Offerings to redeem up to an aggregate of 35% of the
principal amount of the Securities originally issued, at a Redemption Price
equal to 111.625% of the principal amount thereof plus accrued and unpaid
interest, if any, thereon to the Redemption Date; provided, however, at least
65% of the originally issued principal amount of Securities remains outstanding
immediately after the occurrence of such redemption. In order to effect the
foregoing redemption with the proceeds of any Public Equity Offering, the
Company must consummate such redemption not later than 60 days after the closing
of any such Public Equity Offering.




                                     A-1-5
<PAGE>   105

         The Securities are not subject to any sinking fund.

         The Indenture provides that the Company is obligated (a) upon the
occurrence of a Change in Control to make an offer to purchase all outstanding
Securities at a purchase price equal to 101% of the principal amount thereof,
plus accrued and unpaid interest, if any, thereon to the date of purchase and
(b) to make an offer to purchase Securities with a portion of the net cash
proceeds of certain sales or other dispositions of assets (not applied as
specified in the Indenture within the periods set forth therein) at a purchase
price equal to 100% of the principal amount thereof plus accrued and unpaid
interest, if any, to the date of purchase.

         In the event of redemption or purchase of this Security in part only
pursuant to a Change of Control Offer or an Asset Sale Offer, a new Security or
Securities for the unredeemed or unpurchased portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

         The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Security or of certain restrictive covenants and
Events of Default with respect to this Security, in each case upon compliance
with certain conditions set forth in the Indenture.

         If an Event of Default shall occur and be continuing, there may be
declared due and payable the principal of, premium, if any, and accrued and
unpaid interest, if any, on all of the outstanding Securities, in the manner and
with the effect provided in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities, the Holders of not less than 25% in principal amount of the
Securities at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to certain
suits described in the Indenture, including any suit instituted by the Holder of
this Security for the enforcement of





                                     A-1-6
<PAGE>   106

any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein (or, in the case of redemption, on or
after the Redemption Date or, in the case of any purchase of this Security
required to be made pursuant to a Change of Control Offer or an Asset Sale
Offer, on or after the relevant Purchase Date).

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

         This Security is issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of like tenor
of a different authorized denomination, as requested by the Holder surrendering
the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         Pursuant to the Registration Rights Agreement by and among the Company
and the Initial Purchasers, the Company will be obligated to consummate an
exchange offer pursuant to which the Holder of this Security shall have the
right to exchange this Security for 11 5/8% Senior Subordinated Notes due 2008,
Series B, of the Company (herein called the "Exchange Securities"), which have
been registered under the Securities Act, in like principal amount and having
identical terms as the Initial Securities (other than as set forth in this
paragraph). The Holders of Initial Securities shall be entitled to receive
certain additional interest payments in the event such exchange offer is not
consummated and upon certain other conditions, all pursuant to and in accordance
with the terms of the Registration Rights Agreement.

         Interest on this Security shall be computed on the basis of a 360-day
year of twelve 30-day months.

are expressly subordinated to all Senior Indebtedness and senior in right of
payment to all Subordinated Indebtedness, in each case to the extent set forth
in Article XIV of the Indenture, and reference is hereby made to such Indenture
for the precise terms of such subordination.

         As provided in the Indenture and subject to certain limitations therein
set forth, the obligations of the Company under the Indenture and this Security
are Guaranteed pursuant to Guarantees as provided in the Indenture. Each Holder,
by holding this Security, agrees to all of the terms and provisions of said
Guarantees. The Indenture provides that each Guarantor shall be released from
its Guaranty upon compliance with certain conditions.

         All terms used in this Security which are defined in the Indenture

paid or duly provided for, semiannually in arrears on April 15 and October 15 in
each year, commencing October 15, 1999 at the rate of 11 5/8% per annum, until
the principal hereof is paid or duly provided for, provided that any principal
and premium, and any such installment of interest, which is overdue shall bear

such interest shall be legally enforceable), from the dates such amounts are due
until they are paid or duly provided for. The interest so payable and punctually

predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities not less than 10
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange

by such exchange, all as more fully provided in said Indenture.

         Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose, in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that, at the option of the Company, payment of interest may be made by
check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register (subject to the right of certain holders to
request payment by wire transfer as provided in the Indenture).

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

at Stated Maturity to $250,000,000 issued and to be issued under an Indenture,

the Indenture), and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered. The

single class of securities under the Indenture.

         The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S.C. Sections 7aaa - 77bbbb) (the "TIA"), as in effect on the date of the

         Year                                                       Price

<S>                                                               <C>

principal amount of the Securities originally issued, at a Redemption Price
equal to 111.625% of the principal amount thereof plus accrued and unpaid
interest, if any, thereon to the Redemption Date; provided, however, at least
65% of the originally issued principal amount of Securities remains outstanding

foregoing redemption with the proceeds of any Public Equity Offering, the
Company shall consummate such redemption not later than 60 days after the
closing of any such Public Equity Offering.

         The Securities are not subject to any sinking fund.

         The Indenture provides that the Company is obligated (a) upon the
occurrence of a Change in Control to make an offer to purchase all outstanding
Securities at a purchase price equal to 101% of the principal amount thereof,
plus accrued and unpaid interest, if any, thereon to the date of purchase and
(b) to make an offer to purchase Securities with a portion of the net cash
proceeds of certain sales or other dispositions of assets (not applied as
specified in the Indenture within the periods set forth therein) at a purchase
price equal to 100% of the principal amount thereof plus accrued and unpaid
interest, if any, to the date of purchase.

         In the event of redemption or purchase of this Security in part only
pursuant to a Change of Control Offer or an Asset Sale Offer, a new Security or
Securities for the unredeemed or unpurchased portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

         The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Security or of certain restrictive covenants and
Events of Default with respect to this Security, in each case upon compliance
with certain conditions set forth in the Indenture.

         If an Event of Default shall occur and be continuing, there may be
declared due and payable the principal of, premium, if any, and accrued and
unpaid interest, if any, on all of the outstanding Securities, in the manner and
with the effect provided in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities, the Holders of not less than 25% in principal amount of the
Securities at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to certain
suits described in the Indenture, including any suit instituted by the Holder of
this Security for the enforcement of




                                     A-2-5
<PAGE>   116

any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein (or, in the case of redemption, on or
after the Redemption Date or, in the case of any purchase of this Security
required to be made pursuant to a Change of Control Offer or an Asset Sale
Offer, on or after the relevant Purchase Date).

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

         The obligations of the Company under the Indenture and this Security
are expressly subordinated to all Senior Indebtedness, in each case to the
extent set forth in Article XIV of the Indenture, and reference is hereby made
to such Indenture for the precise terms of such subordination.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

         This Security is issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of like tenor
of a different authorized denomination, as requested by the Holder surrendering
the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the

year of twelve 30-day months.

set forth, the obligations of the Company under the Indenture and this Security
are Guaranteed pursuant to Guarantees as provided in the Indenture. Each Holder,
by holding this Security, agrees to all of the terms and provisions of said
Guarantees. The Indenture provides that each Guarantor shall be released from

to the Holders, in exchange for the Registrable Securities (other than Private

(C) use their reasonable best efforts to keep the Exchange Offer Registration
Statement effective until the closing of the Exchange Offer and (D) use their

than 180 days following the Closing Date. The Exchange Securities will be issued
under the Indenture. Upon the effectiveness of the Exchange Offer Registration
Statement, the Company and the Guarantors shall promptly commence the Exchange
Offer, it being the objective of such Exchange Offer to enable each Holder
eligible and electing to exchange Registrable Securities for Exchange Securities
(assuming that such Holder (a) is not an affiliate of the Company within the
meaning of Rule 405 under the 1933 Act, (b) is not a broker-dealer tendering
Registrable Securities acquired directly from the Company for its own account,
(c) acquired the Registrable Securities in the ordinary course of such Holder's
business and (d) has no arrangements or understandings with any Person to
participate in the Exchange Offer for the purpose of distributing the Exchange
Securities) to transfer such Exchange Securities from and after their receipt
without any limitations or restrictions under the 1933 Act or under state
securities or blue sky laws.

         In connection with the Exchange Offer, the Company shall:

                  (a) mail as promptly as practicable to each Holder a copy of
         the Prospectus forming part of the Exchange Offer Registration
         Statement, together with an appropriate letter of transmittal and
         related documents;

                  (b) keep the Exchange Offer open for acceptance for a period
         of not less than 30 calendar days after the date notice thereof is
         mailed to the Holders (or longer if required by applicable law) (such
         period referred to herein as the "Exchange Period");

                  (c) utilize the services of the Depositary for the Exchange
         Offer;

                  (d) permit Holders to withdraw tendered Registrable Securities
         at any time prior to 5:00 p.m. (Eastern Time) on the last business day
         of the Exchange Period, by sending to the institution specified in the
         notice a telegram, telex, facsimile transmission or letter setting
         forth the name of such Holder, the principal amount of Registrable
         Securities delivered for exchange, and a statement that such Holder is
         withdrawing such Holder's election to have such Securities exchanged;

                  (e) notify each Holder that any Registrable Security not
         tendered will remain outstanding and continue to accrue interest, but
         will not retain any rights under this Agreement (except in the case of
         the Initial Purchasers and Participating Broker-Dealers as provided
         herein); and


                                      -4-
<PAGE>   5

                  (f) otherwise comply in all respects with all applicable laws
         relating to the Exchange Offer.

         If, prior to consummation of the Exchange Offer, the Initial Purchasers
hold any Securities acquired by them and having the status of an unsold
allotment in the initial distribution, the Company and the Guarantors upon the
request of any Initial Purchaser shall, simultaneously with the delivery of the
Exchange Securities in the Exchange Offer, issue and deliver to such Initial
Purchaser in exchange (the "Private Exchange") for the Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company and
related guarantees by the Guarantors that are identical (except that such
securities shall bear appropriate transfer restrictions) to the Exchange
Securities (the "Private Exchange Securities").

         The Exchange Securities and the Private Exchange Securities shall be
issued under (i) the Indenture or (ii) an indenture identical in all material
respects to the Indenture and which, in either case, has been qualified under
the Trust Indenture Act of 1939, as amended (the "TIA"), or is exempt from such
qualification and shall provide that the Exchange Securities shall not be
subject to the transfer restrictions applicable to the Registrable Securities
set forth in the Indenture but that the Private Exchange Securities shall be
subject to such transfer restrictions. The Indenture or such indenture shall
provide that the Exchange Securities, the Private Exchange Securities and the
Securities shall vote and consent together on all matters as one class and that
none of the Exchange Securities, the Private Exchange Securities or the
Securities will have the right to vote or consent as a separate class on any
matter. The Private Exchange Securities shall be of the same series as and the
Company shall use all commercially reasonable efforts to have the Private
Exchange Securities bear the same CUSIP number as the Exchange Securities. The
Company shall not have any liability under this Agreement solely as a result of
such Private Exchange Securities not bearing the same CUSIP number as the
Exchange Securities.

         As soon as practicable after the close of the Exchange Offer and/or the
Private Exchange, as the case may be, the Company and the Guarantors shall:

                  (i) accept for exchange all Registrable Securities duly
         tendered and not validly withdrawn pursuant to the Exchange Offer in
         accordance with the terms of the Exchange Offer Registration Statement
         and the letter of transmittal which shall be an exhibit thereto;

                 (ii) accept for exchange all Securities properly tendered
         pursuant to the Private Exchange;

                  (iii) deliver to the Trustee for cancellation all Registrable
         Securities so accepted for exchange; and

                 (iv) cause the Trustee promptly to authenticate and deliver
         Exchange Securities or Private Exchange Securities, as the case may be,
         to each Holder of Registrable Securities so accepted for exchange in a
         principal amount equal to the principal amount of the Registrable
         Securities of such Holder so accepted for exchange.

         Interest on each Exchange Security and Private Exchange Security will
accrue from the last date on which interest was paid on the Registrable
Securities surrendered in exchange therefor or, if no interest has been paid on
the Registrable Securities, from the date of original issuance. The Exchange
Offer and the Private Exchange shall not be subject to any conditions, other
than (i) that the Exchange Offer or the Private Exchange, or the making of any
exchange by a Holder, does not violate applicable law or any applicable
interpretation of the staff of the SEC, (ii) the due tendering of Registrable
Securities in accordance with the Exchange Offer and the Private Exchange, (iii)
that each Holder of Registrable Securities exchanged in the Exchange Offer shall
have represented that all Exchange Securities to be received by it shall be
acquired in the ordinary course of its business and that at the time of the
consummation of the Exchange Offer it shall have no arrangement or understanding


                                      -5-
<PAGE>   6

with any person to participate in the distribution (within the meaning of the
1933 Act) of the Exchange Securities and shall have made such other
representations as may be reasonably necessary under applicable SEC rules,
regulations or interpretations to render the use of Form S-4 or other
appropriate form under the 1933 Act available and (iv) that no action or
proceeding shall have been instituted or threatened in any court or by or before
any governmental agency with respect to the Exchange Offer or the Private
Exchange which, in the Company's judgment, would reasonably be expected to
impair the ability of the Company to proceed with the Exchange Offer or the
Private Exchange. The Company shall inform the Initial Purchasers of the names
and addresses of the Holders to whom the Exchange Offer is made, and the Initial
Purchasers shall have the right to contact such Holders and otherwise facilitate
the tender of Registrable Securities in the Exchange Offer.

         2.2 Shelf Registration. (i) If, because of any changes in law, SEC
rules or regulations or applicable interpretations thereof by the staff of the
SEC, the Company is not permitted to effect the Exchange Offer as contemplated
by Section 2.1 hereof, (ii) if for any other reason the Exchange Offer
Registration Statement is not declared effective within 150 days following the
original issue of the Registrable Securities or the Exchange Offer is not
consummated within 180 days after the original issue of the Registrable
Securities, (iii) upon the request of any of the Initial Purchasers or (iv) if a
Holder is not permitted to participate in the Exchange Offer or does not receive
fully tradeable Exchange Securities pursuant to the Exchange Offer, then in case
of each of clauses (i) through (iv) the Company and the Guarantors shall, at the
Company's cost:

                  (a) As promptly as practicable, file with the SEC, and
         thereafter shall use their reasonable best efforts to cause to be
         declared effective as promptly as practicable but no later than 150
         days after the date the obligation to file the Shelf Registration
         Statement arises, a Shelf Registration Statement relating to the offer
         and sale of the Registrable Securities by the Holders from time to time
         in accordance with the methods of distribution elected by the Majority
         Holders participating in the Shelf Registration and set forth in such
         Shelf Registration Statement.

                  (b) Use their reasonable best efforts to keep the Shelf
         Registration Statement continuously effective in order to permit the
         Prospectus forming part thereof to be usable by Holders for a period of
         two years from the date the Shelf Registration Statement is declared
         effective by the SEC, or for such shorter period that will terminate
         when all Registrable Securities covered by the Shelf Registration
         Statement have been sold pursuant to the Shelf Registration Statement
         or cease to be outstanding or otherwise cease to be Registrable
         Securities (the "Effectiveness Period"); provided, however, that the
         Effectiveness Period in respect of the Shelf Registration Statement
         shall be extended to the extent required to permit dealers to comply
         with the applicable prospectus delivery requirements of Rule 174 under
         the 1933 Act and as otherwise provided herein; and provided, further,
         that the Company and the Guarantors shall not be obligated to keep the
         Shelf Registration Statement effective or to permit the use of any
         Prospectus forming a part of the Shelf Registration Statement if (A)
         the Company determines, in its reasonable judgment, upon advice of
         counsel, that the continued effectiveness and use of the Shelf
         Registration Statement would (x) require the disclosure of material
         information which the Company has a bona fide business reason for
         preserving as confidential, or (y) interfere with any financing,
         acquisition, corporate reorganization or other material transaction
         involving the Company or any of its subsidiaries, and provided,
         further, that the failure to keep the Shelf Registration Statement
         effective and usable for offers and sales of Registrable Securities for
         such reasons shall last no longer than an aggregate of 30 days in any
         consecutive twelve-month period (whereafter a Registration Default, as
         defined in Section 2.5, shall occur), and (B) the Company promptly
         thereafter complies with the requirements of Section 3(k) hereof, if
         applicable (any such period during which the Company is excused from
         keeping the Shelf Registration Statement effective and usable for
         offers and sales of Registrable Securities is referred to herein as a
         "Suspension Period", and a Suspension Period shall commence on and
         include the date that the Company gives notice to the Holders that the
         Shelf Registration Statement is no longer effective or the prospectus
         included therein is no longer usable for offers and sales of
         Registrable Securities as a result of the foregoing provisions and
         shall end on the earlier to occur of the date


                                      -6-
<PAGE>   7

         on which each seller of Registrable Securities covered by the Shelf
         Registration Statement either receives the copies of the supplemented
         or amended prospectus contemplated by Section 3(k) hereof or is advised
         in writing by the Company that use of the prospectus may be resumed);
         and

                  (c) use their reasonable best efforts to ensure that (i) any
         Shelf Registration Statement and any amendment thereto and any
         Prospectus forming part thereof and any supplement thereto complies in
         all material respects with the 1933 Act and the rules and regulations
         thereunder, (ii) any Shelf Registration Statement and any amendment
         thereto does not, when it becomes effective, contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading and (iii) subject to Section 2(b) above, any Prospectus
         forming part of any Shelf Registration Statement, and any supplement to
         such Prospectus (as amended or supplemented from time to time), does
         not include an untrue statement of a material fact or omit to state a
         material fact necessary in order to make the statements, in light of
         the circumstances under which they were made, not misleading.

         The Company shall not permit any securities other than Registrable
Securities to be included in the Shelf Registration Statement. The Company and
the Guarantors further agree, if necessary, to supplement or amend the Shelf
Registration Statement, as required by Section 3(b) below, and to furnish to the
Holders of Registrable Securities copies of any such supplement or amendment
promptly after its being used or filed with the SEC.

         2.3 Expenses. The Company shall pay all Registration Expenses in
connection with the registration pursuant to Section 2.1 or 2.2. Each Holder
shall pay all underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Registrable Securities
pursuant to the Shelf Registration Statement.

         2.4 Effectiveness. (a) The Company and the Guarantors will be deemed
not to have used their reasonable best efforts to cause the Exchange Offer
Registration Statement or the Shelf Registration Statement, as the case may be,
to become, or to remain, effective during the requisite period if they
voluntarily take any action that would, or omits to take any action which
omission would, result in any such Registration Statement not being declared
effective or in the Holders of Registrable Securities covered thereby not being
able to exchange or offer and sell such Registrable Securities during that
period as and to the extent contemplated hereby, unless such action is required
by applicable law.

         (b) An Exchange Offer Registration Statement pursuant to Section 2.1
hereof or a Shelf Registration Statement pursuant to Section 2.2 hereof will not
be deemed to have become effective unless it has been declared effective by the
SEC; provided, however, that if, after it has been declared effective, the
offering of Registrable Securities pursuant to an Exchange Offer Registration
Statement or a Shelf Registration Statement is interfered with by any stop
order, injunction or other order or requirement of the SEC or any other
governmental agency or court, such Registration Statement will be deemed not to
have become effective during the period of such interference, until the offering
of Registrable Securities pursuant to such Registration Statement may legally
resume.

         2.5 Additional Interest. The Indenture executed in connection with the
Securities will provide that in the event that either (a) the Exchange Offer
Registration Statement is not filed with the Commission on or prior to the 60th
calendar day following the date of original issue of the Securities, (b) the
Exchange Offer Registration Statement has not been declared effective on or
prior to the 150th calendar day following the date of original issue of the
Securities , (c) the Exchange Offer is not consummated on or prior to the 180th
calendar day following the date of original issue of the Securities or a Shelf
Registration Statement is not declared effective prior to the 150th day
following the date the obligation to file such Shelf Registration Statement
arises or (d) after the Shelf Registration Statement has been filed and declared
effective, the Shelf Registration Statement is


                                      -7-
<PAGE>   8

unusable by the Holders for any reason during the Effectiveness Period, and the
aggregate number of days in any consecutive twelve-month period for which the
Shelf Registration Statement shall not be usable exceeds 30 days in the
aggregate (each such event referred to in clauses (a) through (d) above, a
"Registration Default"), the interest rate borne by the Registrable Securities
shall be increased ("Additional Interest") by 0.25% per annum upon the
occurrence of each Registration Default, which rate will increase by 0.25% per
annum each 90-day period that such Additional Interest continues to accrue under
any such circumstance, provided that the maximum aggregate increase in the
interest rate will in no event exceed 0.50% per annum. Additional Interest shall
be computed based on the actual number of days elapsed in each period in which a
Registration Default occurs. Following the cure of all Registration Defaults the
accrual of Additional Interest will cease and the interest rate will revert to
the original rate.

         The Company shall notify the Trustee within three business days after
each and every date on which an event occurs in respect of which Additional
Interest is required to be paid (an "Event Date"). Additional Interest shall be
paid by depositing with the Trustee, in trust, for the benefit of the Holders of
Registrable Securities, on or before the applicable semiannual interest payment
date, immediately available funds in sums sufficient to pay the Additional
Interest then due. The Additional Interest due shall be payable on each interest
payment date to the record Holder of Securities entitled to receive the interest
payment to be paid on such date as set forth in the Indenture. Each obligation
to pay Additional Interest shall be deemed to accrue from and including the day
following the applicable Event Date.

Company with respect to Registration Statements pursuant to Sections 2.1 and 2.2
hereof, the Company (and, as necessary, the Guarantors) shall:

                  (a) prepare and file with the SEC a Registration Statement,

         Section 2 hereof;

                  (b) prepare and file with the SEC such amendments and

         Broker-Dealer);

         Holder of Registrable Securities, at least five business days prior to

         with the method selected by the Majority Holders participating in the
         Shelf Registration; (ii) furnish to each Holder of Registrable

         including financial statements and schedules, in order to facilitate
         the public sale or other disposition of the Registrable Securities; and

         Securities covered by the Prospectus or any amendment or supplement
         thereto;

                  (d) use its reasonable best efforts to register or qualify the
         Registrable Securities under all applicable state securities or "blue
         sky" laws of such jurisdictions as any Holder of Registrable Securities
         covered by a Registration Statement and each underwriter of an
         underwritten offering of Registrable Securities shall reasonably
         request by the time the applicable Registration Statement is declared
         effective by the SEC, and do any and all other acts and things which
         may be reasonably necessary or advisable to enable each such Holder and
         underwriter to consummate the disposition in each such jurisdiction of
         such Registrable Securities owned by such Holder; provided, however,
         that the Company shall not be required to (i) qualify as a foreign
         corporation or as a dealer in securities in any jurisdiction where it
         would not otherwise be required to qualify but for this Section 3(d),
         or (ii) take any action which would subject it to general service of
         process or taxation in any such jurisdiction where it is not then so
         subject;

                  (e) notify promptly each Holder of Registrable Securities
         included in a Shelf Registration or any Participating Broker-Dealer who

         requested by such Holder or Participating Broker-Dealer, confirm such
         advice in writing promptly (i) when a Registration Statement has become

         of any event or the discovery of any facts during the period a Shelf

         such Registration Statement or the related Prospectus untrue in any
         material respect or which requires the making of any changes in such
         Registration Statement or Prospectus in order to make the statements
         therein not misleading or to include omitted material information, (v)
         of the receipt by the Company of any notification with respect to the
         suspension of the qualification of the Registrable Securities or the

         account as a result of market-making activities or other trading
         activities and that will be the beneficial owner (as defined in Rule
         13d-3 under the Exchange Act) of Exchange Securities to be received by
         such broker-dealer in the Exchange Offer, whether such positions or

         statements are, or are required to be, included in the Registration
         Statement) at least as broad in scope and coverage as the comfort
         letter or comfort letters delivered to the Initial Purchasers in
         connection with the initial sale of the Securities to the Initial
         Purchasers;

                  (g) (i) in the case of an Exchange Offer, furnish counsel for
         the Initial Purchasers and (ii) in the case of a Shelf Registration,

         such names as


                                      -10-
<PAGE>   11

         the selling Holders or the underwriters, if any, may reasonably request
         at least three business days prior to the closing of any sale of
         Registrable Securities;

                  (k) in the case of a Shelf Registration, upon the occurrence
         of any event or the discovery of any facts, each as contemplated by
         Sections 3(e)(iv) and 3(e)(v) hereof, as promptly as practicable after
         the occurrence of such an event, subject to Section 2.2(b), use its
         reasonable best efforts to prepare a supplement or post-effective
         amendment to the Registration Statement or the related Prospectus or
         any document incorporated therein by reference or file any other
         required document so that, as thereafter delivered to the purchasers of
         the Registrable Securities or Participating Broker-Dealers, such
         Prospectus will not contain at the time of such delivery any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements therein, in light of the circumstances under
         which they were made, not misleading or will remain so qualified. At
         such time as such public disclosure is otherwise made or the Company
         determines that such disclosure is not necessary, in each case to
         correct any misstatement of a material fact or to include any omitted
         material fact, the Company agrees promptly to notify each Holder of
         such determination and to furnish each Holder such number of copies of

         into a Registration Statement or a Prospectus after initial filing of a
         Registration Statement, provide copies of such document to the Initial
         Purchasers on behalf of such Holders; and make representatives of the
         Company as shall be reasonably requested by the holders of a majority

         Private Exchange Securities or the Registrable Securities, as the case

                  Registrable Securities being sold) addressed to each selling

                  Company for which financial statements are, or are required to
                  be, included in the Registration Statement) addressed to the
                  underwriters, if any, and use reasonable efforts to have such
                  letter addressed to the selling Holders of Registrable
                  Securities (to the extent consistent with Statement on
                  Auditing Standards No. 72 of the American Institute of
                  Certified Public Accounts), such letters to be in customary

                  procedures substantially equivalent to the indemnification
                  provisions and procedures set forth in Section 4 hereof with
                  respect to the underwriters and all other parties to be
                  indemnified pursuant to said Section or, at the request of any
                  underwriters, in the form customarily provided to such

                  reasonably requested and as are customarily delivered in
                  similar offerings to the Holders of a majority in principal
                  amount of the Registrable Securities being sold and the
                  managing underwriters, if any.

         Securities, whether under any underwriting or similar agreement or
         otherwise;

                  (p) in the case of a Shelf Registration or if a Prospectus is

         by representatives appointed by the Majority Holders, any underwriters
         participating in any disposition pursuant to a Shelf Registration
         Statement, any Participating Broker-Dealer and any counsel or
         accountant retained by any of the foregoing, all financial and other
         records, pertinent corporate documents and properties of the Company

         underwriter, special counsel or accountant in connection with a

         amendment to an Exchange Offer Registration Statement or amendment or
         supplement to such Prospectus, provide copies of such document to the
         Initial Purchasers and to counsel to the Majority Holders and make such
         changes in any such document prior to the filing thereof as the Initial
         Purchasers may reasonably request and, except as otherwise required by
         applicable law, not file any such document in a form to which the
         Initial Purchasers on behalf of the Holders of Registrable Securities
         and


                                      -12-
<PAGE>   13

         counsel to the Majority Holders shall not have previously been advised
         and furnished a copy of or to which the Initial Purchasers on behalf of
         the Holders of Registrable Securities or counsel to the Majority
         Holders shall reasonably object, and make the representatives of the
         Company available for discussion of such documents as shall be
         reasonably requested by the Initial Purchasers; and

                 (ii) in the case of a Shelf Registration, a reasonable time
         prior to filing any Shelf Registration Statement, any Prospectus
         forming a part thereof, any amendment to such Shelf Registration
         Statement or amendment or supplement to such Prospectus, provide copies
         of such document to the Holders of Registrable Securities, to the
         Initial Purchasers, to counsel for the Holders and to the underwriter
         or underwriters of an underwritten offering of Registrable Securities,
         if any, make such changes in any such document prior to the filing
         thereof as the Initial Purchasers, the counsel to the Holders or the
         underwriter or underwriters reasonably request and not file any such
         document in a form to which the Majority Holders, the Initial
         Purchasers on behalf of the Holders of Registrable Securities, counsel
         for the Holders of Registrable Securities or any underwriter shall not
         have previously been advised and furnished a copy of or to which the
         Majority Holders, the Initial Purchasers of behalf of the Holders of
         Registrable Securities, counsel to the Holders of Registrable
         Securities or any underwriter shall reasonably object, and make the
         representatives of the Company available for discussion of such
         document as shall be reasonably requested by the Holders of Registrable
         Securities, the Initial Purchasers on behalf of such Holders, counsel
         for the Holders of Registrable Securities or any underwriter;

                  (r) otherwise comply with all applicable rules and regulations
         of the SEC and make available to its security holders, as soon as
         reasonably practicable, an earnings statement covering at least 12
         months which shall satisfy the provisions of Section 11(a) of the 1933
         Act and Rule 158 thereunder;

                  (s) cooperate and assist in any filings required to be made
         with the NASD and, in the case of a Shelf Registration, in the
         performance of any due diligence investigation by any underwriter and
         its counsel (including any "qualified independent underwriter" that is
         required to be retained in accordance with the rules and regulations of
         the NASD); and

                  (t) upon consummation of an Exchange Offer or a Private
         Exchange, obtain a customary opinion of counsel to the Company and the
         Guarantors addressed to the Trustee for the benefit of all Holders of
         Registrable Securities participating in the Exchange Offer or Private
         Exchange, and which includes an opinion that (i) the Company and the
         Guarantors have duly authorized, executed and delivered the Exchange
         Securities and/or Private Exchange Securities, as applicable, and the
         related indenture, and (ii) each of the Exchange Securities and related
         indenture constitute a legal, valid and binding obligation of the
         Company and the Guarantors, enforceable against the Company and the
         Guarantors in accordance with its respective terms (with customary
         exceptions).

         In the case of a Shelf Registration Statement, the Company may (as a
condition to such Holder's participation in the Shelf Registration) require each
Holder of Registrable Securities to furnish to the Company such information
regarding the Holder and the proposed distribution by such Holder of such
Registrable Securities as the Company may from time to time reasonably request
in writing.

         In the case of a Shelf Registration Statement, each Holder agrees that,
upon receipt of any notice from the Company of (a) the happening of any event or
the discovery of any facts, each of the kind described in Section 3(e)(iv)
hereof or (b) the Company's election to begin a Suspension Period pursuant to
Section 2.2(b), such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(k) hereof or written notice from the Company of termination of such
Suspension Period, and, if so directed by the Company, such Holder will deliver
to the Company (at the Company's expense) all copies in such Holder's


                                      -13-
<PAGE>   14

possession, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities current at the time of
receipt of such notice.

         If any of the Registrable Securities covered by any Shelf Registration
Statement are to be sold in an underwritten offering, the underwriter or
underwriters and manager or managers that will manage such offering will be
selected by the Majority Holders of such Registrable Securities included in such
offering and shall be acceptable to the Company. No Holder of Registrable
Securities may participate in any underwritten registration hereunder unless
such Holder (a) agrees to sell such Holder's Registrable Securities on the basis
provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and (b) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements.

         4. Indemnification; Contribution.

         (a) The Company and the Guarantors jointly and severally agree to
indemnify and hold harmless the Initial Purchasers, each Holder, each
Participating Broker-Dealer, each Person who participates as an underwriter (any
such Person being an "Underwriter") and each Person, if any, who controls any
Holder or Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act as follows:

                  (i) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged untrue statement of a material fact contained in any
         Registration Statement (or any amendment or supplement thereto)
         pursuant to which Exchange Securities or Registrable Securities were
         registered under the 1933 Act, including all documents incorporated
         therein by reference, or the omission or alleged omission therefrom of
         a material fact required to be stated therein or necessary to make the
         statements therein not misleading, or arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         any Prospectus (or any amendment or supplement thereto) or the omission
         or alleged omission therefrom of a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading;

                 (ii) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission; provided
         that (subject to Section 4(d) below) any such settlement is effected
         with the written consent of the Company; and

                (iii) against any and all expense whatsoever, as incurred
         (including the fees and disbursements of counsel chosen by any
         indemnified party), reasonably incurred in investigating, preparing or
         defending against any litigation, or any investigation or proceeding by
         any governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Holder or Underwriter expressly for use in a Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto).



                                      -14-
<PAGE>   15

         (b) Each Holder severally, but not jointly, agrees to indemnify and
hold harmless the Company, the Guarantors, the Initial Purchasers, each
Underwriter and the other selling Holders, and each of their respective
directors and officers, and each Person, if any, who controls the Company, any
Guarantor, any Initial Purchaser, any Underwriter or any other selling Holder
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act,
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in Section 4(a) hereof, as incurred, but only with respect
to untrue statements or omissions, or alleged untrue statements or omissions,
made in the Shelf Registration Statement (or any amendment thereto) or any
Prospectus included therein (or any amendment or supplement thereto) in reliance
upon and in conformity with written information with respect to such Holder
furnished to the Company by such Holder expressly for use in the Shelf
Registration Statement (or any amendment thereto) or such Prospectus (or any
amendment or supplement thereto); provided, however, that no such Holder shall
be liable for any claims hereunder in excess of the amount of net proceeds
received by such Holder from the sale of Registrable Securities pursuant to such
Registration Statement.

         (c) Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action or proceeding commenced
against it in respect of which indemnity may be sought hereunder, but failure so
to notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. An indemnifying
party may participate at its own expense in the defense of such action;
provided, however, that counsel to the indemnifying party shall not (except with
the consent of the indemnified party) also be counsel to the indemnified party.
In no event shall the indemnifying party or parties be liable for the fees and
expenses of more than one counsel (in addition to any local counsel) separate
from their own counsel for all indemnified parties in connection with any one
action or separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances. No indemnifying
party shall, without the prior written consent of the indemnified parties,
settle or compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 4 (whether or
not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) includes an unconditional release of
each indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

         (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement; provided,
however, that an indemnifying party shall not be liable for any such settlement
effected without its consent if such indemnifying party, prior to the date of
such settlement, (1) reimburses such indemnified party in accordance with such
request for the amount of such fees and expenses of counsel as the indemnifying
party believes in good faith to be reasonable, and (2) provides written notice
to the indemnified party that the indemnifying party disputes in good faith the
reasonableness of the unpaid balance of such fees and expenses.

         (e) If the indemnification provided for in this Section 4 is for any
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party shall contribute to the aggregate amount
of such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, in such proportion as is appropriate to reflect
the relative fault of the Company and the Guarantors on the one hand and the
Holders and the


                                      -15-
<PAGE>   16

Initial Purchasers on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

         The relative fault of the Company and the Guarantors on the one hand
and the Holders and the Initial Purchasers on the other hand shall be determined
by reference to, among other things, whether any such untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the Company, the Guarantors, the Holders
or the Initial Purchasers and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

         The Company, the Guarantors, the Holders and the Initial Purchasers
agree that it would not be just and equitable if contribution pursuant to this
Section 4 were determined by pro rata allocation (even if the Initial Purchasers
were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to above in this Section 4. The aggregate amount of losses, liabilities, claims,
damages and expenses incurred by an indemnified party and referred to above in
this Section 4 shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in investigating, preparing or defending
against any litigation, or any investigation or proceeding by any governmental
agency or body, commenced or threatened, or any claim whatsoever based upon any
such untrue or alleged untrue statement or omission or alleged omission.

         Notwithstanding the provisions of this Section 4, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities sold by it were offered exceeds the amount
of any damages which such Initial Purchaser has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.

         No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 4, each Person, if any, who controls an
Initial Purchaser or Holder within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Initial Purchaser or Holder, and each director of the Company or any Guarantor,
and each Person, if any, who controls the Company or any Guarantor within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have
the same rights to contribution as the Company and the Guarantors. The Initial
Purchasers' respective obligations to contribute pursuant to this Section 4 are
several in proportion to the principal amount of Securities set forth opposite
their respective names in Schedule A to the Purchase Agreement and not joint.

         5. Miscellaneous.

         5.1 Rule 144 and Rule 144A. For so long as the Company is subject to
the reporting requirements of Section 13 or 15 of the 1934 Act, the Company
covenants that it will file the reports required to be filed by it under the
1933 Act and Section 13(a) or 15(d) of the 1934 Act and the rules and
regulations adopted by the SEC thereunder. If the Company ceases to be so
required to file such reports, the Company covenants that it will upon the
request of any Holder of Registrable Securities (a) make publicly available such
information as is necessary to permit sales pursuant to Rule 144 under the 1933
Act, (b) deliver such information to a prospective purchaser as is necessary to
permit sales pursuant to Rule 144A under the 1933 Act and it will take such
further action as any Holder of Registrable Securities may reasonably request,
and (c) take such further action that is reasonable in the circumstances, in
each case, to the extent required from time to time to enable such Holder to
sell its Registrable Securities without registration under the 1933 Act within
the limitation of the exemptions provided by (i) Rule 144 under the 1933 Act, as
such Rule may be amended from time to time, (ii) Rule 144A under the 1933 Act,
as such Rule may be amended from time to time, or (iii) any similar rules or
regulations


                                      -16-
<PAGE>   17

hereafter adopted by the SEC. Upon the request of any Holder of Registrable
Securities, the Company will deliver to such Holder a written statement as to
whether it has complied with such requirements.

         5.2 No Inconsistent Agreements. The Company has not entered into and
the Company will not after the date of this Agreement enter into any agreement
which is inconsistent with the rights granted to the Holders of Registrable
Securities in this Agreement or otherwise conflicts with the provisions hereof.
The rights granted to the Holders hereunder do not and will not for the term of
this Agreement in any way conflict with the rights granted to the holders of the
Company's other issued and outstanding securities under any such agreements.

         5.3 Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given unless the Company has obtained the written consent of the Majority
Holders affected by such amendment, modification, supplement, waiver or
departure.

         5.4 Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (a) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 5.4, which address initially is the address set forth in the Purchase
Agreement with respect to the Initial Purchasers; and (b) if to the Company or
any Guarantor, initially at the Company's address set forth in the Purchase
Agreement, and thereafter at such other address of which notice is given in
accordance with the provisions of this Section 5.4.

         All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; two business days
after being deposited in the mail, postage prepaid, if mailed; when answered
back, if telexed; when receipt is acknowledged, if telecopied; and on the next
business day if timely delivered to an air courier guaranteeing overnight
delivery.

         Copies of all such notices, demands, or other communications shall be
concurrently delivered by the person giving the same to the Trustee under the
Indenture, at the address specified in such Indenture.

         5.5 Successor and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement or the Indenture. If any
transferee of any Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Registrable Securities such person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement, including the restrictions on resale set forth in this Agreement and,
if applicable, the Purchase Agreement, and such person shall be entitled to
receive the benefits hereof.

         5.6 Third Party Beneficiaries. The Initial Purchasers (even if the
Initial Purchasers are not Holders of Registrable Securities) shall be third
party beneficiaries to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Holders, on the other hand, and shall have
the right to enforce such agreements directly to the extent they deem such
enforcement necessary or advisable to protect their rights or the rights of
Holders hereunder. Each Holder of Registrable Securities shall be a third party
beneficiary to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights hereunder.

         5.7 Specific Enforcement. Without limiting the remedies available to
the Initial Purchasers and the Holders, the Company and the Guarantors
acknowledge that any failure by the Company and the Guarantors to comply with
their obligations under Sections 2.1 through 2.4 hereof may result in material
irreparable injury to the Initial Purchasers or the Holders for which there is
no adequate remedy at law, that it would not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the Initial
Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the obligations of the Company and the Guarantors under
Sections 2.1 through 2.4 hereof.

         5.8 Restriction on Resales. Until the expiration of two years after the
original issuance of the Securities, the Company and the Guarantors will not
resell any Securities which are "restricted securities" (as such term is defined
under Rule 144(a)(3) under the 1933 Act) that have been reacquired by any of
them and shall immediately upon any purchase of any such Securities submit such
Securities to the Trustee for cancellation.

         5.9 Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

         5.10 Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         5.11 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
PRINCIPLES OF CONFLICT OF LAWS THEREOF. SPECIFIED TIMES OF DAY REFER TO NEW YORK
CITY TIME.

         5.12 Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

                                               New York, NY 10036

Ladies and Gentlemen:

         We have acted as counsel for American Plumbing & Mechanical, Inc., a
Delaware corporation (the "Company") and the Guarantors described below in
connection with the sale by the Company to the Initial Purchasers (as defined
below) of $150,000,000 aggregate principal amount of 11 5/8% Senior Subordinated
Notes due 2009 (the "Notes") of the Company together with the related guarantees
of the obligation of the Company under such Notes, pursuant to the Purchase
Agreement dated May 12, 1999 (the "Purchase Agreement") among the Company, the
Guarantors named therein (the "Guarantors") and Fleet Securities, Inc., Merrill
Lynch, Pierce, Fenner & Smith Incorporated, Banc One Capital Markets, Inc. and
Credit Lyonnais Securities (USA) Inc. (collectively, the "Initial Purchasers")
and the filing by the Company and the Guarantors of an Exchange Offer
Registration Statement (the "Registration Statement") in connection with an
Exchange Offer to be effected pursuant to the Registration Rights Agreement (the
"Registration Rights Agreement"), dated May 19, 1999 among the Company, the
Guarantors and the Initial Purchasers. This opinion is furnished to you pursuant
to Section 3(f)(B) of the Registration Rights Agreement. Unless otherwise
defined herein, capitalized terms used in this opinion that are defined in the
Registration Rights Agreement are used herein as so defined.

         We have examined such documents, records and matters of law as we have
deemed necessary for purposes of this opinion. In rendering this opinion, as to
all matters of fact relevant to this opinion, we have assumed the completeness
and accuracy of, and are relying solely upon, the representations and warranties
of the Company and the Guarantors set forth in the Purchase Agreement and the
statements set forth in certificates of public officials and officers of the
Company and the Guarantors, without making any independent investigation or
inquiry with respect to the completeness or accuracy of such representations,
warranties or statements, other than a review of the certificate of
incorporation, by-laws and relevant minute books of the Company and the
Guarantors.

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

         1. The Exchange Offer Registration Statement and the Prospectus (other
than the financial statements, notes or schedules thereto and other financial
data and supplemental schedules included or incorporated by reference therein or
omitted therefrom and the Form T-1, as to which such counsel need express no
opinion), comply as to form in all material respects with the requirements of
the 1933 Act and the applicable rules and regulations promulgated under the 1933
Act.




<PAGE>   23

         2. We have participated in the preparation of the Registration
Statement and the Prospectus and in the course thereof have had discussions with
representatives of the Underwriters, officers and other representatives of the
Company and the Company's independent public accountants, during which the
contents of the Registration Statement and the Prospectus were discussed. We
have not, however, independently verified and are not passing upon, and do not
assume any responsibility for, the accuracy, completeness or fairness of the
statements contained in the Registration Statement and the Prospectus. Based on
our participation as described above, nothing has come to our attention that
would lead us to believe that the Registration Statement (except for financial
statements and schedules and other financial data included therein as to which
we make no statement) contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus or any
amendment or supplement thereto (except for financial statements and schedules
and other financial data included therein, as to which such counsel need make no
statement), at the time the Prospectus was issued, at the time any such amended
or supplemented Prospectus was issued or at the Closing Time, included or
includes an untrue statement of a material fact or omitted or omits to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

         This opinion is being furnished to you solely for your benefit in
connection with the transactions contemplated by the Registration Rights
Agreement, and may not be used for any other purpose or relied upon by any
person other than you. Except with our prior written consent, the opinions
herein expressed are not to be used, circulated, quoted or otherwise referred to
in connection with any transactions other than those contemplated by the
Registration Rights Agreement by or to any other person.

                                                     Very truly yours,


                                      -2-

Board of Directors
American Plumbing and Mechanical, Inc.
1502 Augusta, Suite 425
Houston, Texas 77057

Ladies and Gentlemen:

                  We have acted as counsel to American Plumbing & Mechanical,
Inc., a Delaware corporation (the "Company"), and are delivering this opinion
in connection with the Company's Registration Statement on Form S-4 (the
"Registration Statement") relating to the registration under the Securities Act
of 1933, as amended (the "Securities Act"), of the offer by the Company to
exchange up to $125,000,000 aggregate principal amount of its 115/8% Senior
Subordinated Notes Due 2008, Series B (the "Exchange Notes") for its existing
115/8% Senior Subordinated Notes Due 2008, Series A (the "Existing Notes"). The
Exchange Notes are proposed to be issued in accordance with the provisions of
the indenture (the "Indenture"), dated as of May 19, 1999, between the Company,
the guarantors named therein (the "Guarantors") and State Street Bank and Trust
Company, as Trustee.

                  In arriving at the opinions expressed below, we have examined
the Registration Statement, the Prospectus contained therein, the Indenture
which is filed as an exhibit to the Registration Statement, and the originals
or copies certified or otherwise identified to our satisfaction of such other
instruments and other certificates of public officials and officers and
representatives of the Company. In all such examinations and for purposes of
our opinions set forth below, we have, with your approval and without
independent investigation, assumed the genuineness of all signatures, the legal
capacity of all natural persons, the authenticity and completeness of all
documents submitted to us as originals, the conformity to the authentic
original documents of all documents submitted to us as copies and that all
documents in respect of which forms were filed with the Securities and Exchange
Commission as exhibits to the Registration Statement will conform in all
material respects to the forms thereof that we have examined. In addition, as
the basis for the opinion hereinafter expressed, we have examined such
statutes, regulations, corporate records and documents, certificates of
corporate and public officials and other instruments as we have deemed
necessary or advisable for the purposes of this opinion.

                  Based on the foregoing, and having due regard for such legal
considerations as we deem relevant, and subject to the qualifications and
limitations set forth below, we are of the opinion that the Exchange Notes and
the guarantee of each of the Guarantors (the "Guarantees"), (a) when



<PAGE>   2


Board of Directors
American Plumbing and Mechanical, Inc.
             , 1999
- -------------
Page 2

the Notes have been exchanged in the manner described in the Registration
Statement, (b) when the Exchange Notes have been duly executed, authenticated,
issued and delivered in accordance with the terms of the Indenture, (c) when
the Indenture has been duly qualified under the Trust Indenture Act of 1939, as
amended, and (d) when applicable provisions of "blue sky" laws have been
complied with, will constitute valid and binding obligations of the Company and
the Guarantors, as applicable, enforceable against the Company and the
Guarantors, as applicable, in accordance with their terms, under the laws of
the State of New York which are expressed to govern the same, except as the
enforcement thereof may be limited by (a) bankruptcy, insolvency,
reorganization, moratorium (including, without limitation, all laws relating to
fraudulent transfers), (b) other similar laws relating to or affecting
enforcement of creditors' rights generally, (c) general principles of equity
(regardless of whether enforcement is considered in a proceeding in equity or
at law) and (d) limitations on the waiver of rights under usury laws, and will
be entitled to the benefits of the Indenture.

                  This opinion is limited in all respects to the laws of the
State of Texas, the State of New York and the Delaware General Corporation Law.
We express no opinion as to, and for the purposes of the opinions set forth
herein, we have conducted no investigation of, and do not purport to be experts
on, any other laws. With respect to each Guarantor which was not organized
under the laws of the State of Texas or the State of Delaware, we have assumed
that the laws of the jurisdiction, organization or formation of such Guarantor
with respect to matters of authorization, execution and delivery do not differ
in any material respect from the laws of the State of Texas in those regards
and have undertaken no investigation of the laws of any jurisdiction or their
effect, if any, on any legal conclusion herein expressed other than, the laws
of the State of Texas, the State of New York and the Delaware General
Corporation Law. We hereby consent to the use of this opinion as an exhibit to
the Registration Statement.

                                       Very truly yours,

         "Option" shall mean an option to purchase Shares granted under the
Plan.

         "Participant" shall mean any Director, Employee or Consultant granted

under the Plan shall be 3,700,000 shares or 15% of the aggregate number of
Shares outstanding determined immediately prior to the grant of such Option. If
any Option is forfeited, terminates or is canceled without the delivery of
Shares, then the Shares covered by such Option, to the extent of such
forfeiture, termination or cancellation, shall again be Shares with respect to
which Options may be granted.

         (b) Sources of Shares Deliverable Under Options. Any Shares delivered
pursuant to an Option may consist, in whole or in part, of authorized and

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 Options may
be granted, (ii) the number and type of Shares (or other securities or
property) subject to outstanding Options, and (iii) the grant or exercise price
with respect to any Option or, if deemed appropriate, make provision for a cash
payment to the holder of an outstanding Option; provided, that the number of
Shares subject to any Option shall always be a whole number.

         SECTION 5.   Eligibility.

         Any Director, Employee or Consultant shall be eligible to be

         (a) Options. Subject to the provisions of the Plan, the Committee
shall have the authority to determine the Participants to whom Options shall be
granted from time to time, the number of Shares to be covered by each Option,
the exercise price therefor and the terms, conditions and limitations
applicable to the exercise of the Option, including the following terms and
conditions and such additional terms and conditions as the Committee shall
determine are not inconsistent with the provisions of the Plan.

             (i) Exercise Price. The exercise price per Share purchasable under
         an Option shall be determined by the Committee.

             (ii) Time and Method of Exercise. The Committee shall determine
         the time or times at which an Option may be exercised in whole or in
         part, and the method or methods by which, and the form or forms in
         which payment of the exercise price with respect thereto may be made
         or deemed to have been made, which may include, without limitation,
         (i) cash or check acceptable to the Company in an amount equal to the
         relevant exercise price, (ii) Shares already-owned by the Participant
         having a Fair Market Value on the exercise date equal to the relevant
         exercise price, (iii) a "cashless-broker" exercise (through procedures
         approved by the Company) pursuant to which Shares delivered in payment
         of the exercise price are valued at the Fair Market Value, (iv) a
         personal note with such terms and security as the Committee deems
         appropriate or other securities or other property having an aggregate
         value, as determined in good faith by the Committee, on the exercise
         date equal to the relevant exercise price or (v) any combination
         thereof.

             (iii) Limits on Transfer of Options.

                   (A) Except as provided in (C) below, each Option, and each
             right under any Option, shall be exercisable only by the
             Participant during the Participant's lifetime, or by the person to
             whom the Participant's rights shall pass by will or the laws of
             descent and distribution.

                   (B) Except as provided in (C) below, no Option and no right
             under any such Option 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 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, an Option may be transferred to immediate family members
             or related family trusts, limited partnerships or similar entities
             or on such terms and conditions as the Committee may establish.

             (iv) Term of Options, etc. The term of each Option shall be for
         such period as may be determined by the Committee; provided, that in
         no event shall the term of any Option exceed a period of 10 years from
         the date of its grant. The Committee shall have the discretion at any
         time while an Option remains outstanding to accelerate the vesting of,
         reduce the exercise price of, and/or to extend the period of time for
         which the Option is to remain exercisable following the Participant's
         termination, but in no event may an extension be beyond the expiration
         of the Option's term.

             (v) Share Certificates. All certificates for Shares or other
         securities of the Company or any Affiliate delivered under the Plan
         pursuant to any Option or the exercise


                                      -4-

<PAGE>   5



         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 federal or state
         securities laws, 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) Delivery of Shares or other Securities and Payment by
         Participant of Consideration. No Shares or other securities shall be
         delivered pursuant to any Option until payment in full of any amount
         required to be paid pursuant to the Plan or the applicable Option
         agreement (including, without limitation, any exercise price and
         applicable tax withholding) is received by the Company. Such tax
         withholding payments 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, or property, withholding
         of Shares, cashless exercise with simultaneous sale, or any
         combination thereof.

             (vii) Stockholders' Agreement. The Committee may condition the
         grant and/or exercise of any Option upon the Participant's already
         being, or becoming subject to, a stockholders' agreement covering,
         inter alia, the transferability of the Shares, rights of the Company
         to repurchase such Shares and such other matters as the Committee
         deems appropriate.

             (viii) Securities Laws Compliance. Unless the Stock has been
         registered under the Securities Act of 1933 (and, in the case of any
         Participant who may be deemed an affiliate of the Company for
         securities law purposes, such Stock has been registered under such Act
         for resale by such Participant), or the Company has determined that an
         exemption from registration is available, the Company may require
         prior to and as a condition of the exercise of any Option that (i) the
         Participant desiring to exercise such Option give the Company written
         notice of a desire to exercise such Option and that notice of exercise
         may not be given by the Participant until 45 days thereafter (which
         time period may be waived by the Committee in its sole discretion) in
         order to allow the Company the opportunity to provide to such
         Participant any disclosure materials, or to make such filings, as may
         be required under federal and state securities laws and (ii) the
         Participant desiring to exercise such Option furnish the Company with
         a written representation in a form prescribed by the Board to the
         effect that such person is acquiring said Stock solely with a view to
         investment for his or her own account and not with a view to the
         resale or distribution of all or any part thereof, and that such
         person will not dispose of any of such Stock otherwise than in
         accordance with the provisions of Rule 144 under the Act unless and
         until either the shares of Common Stock are registered under the Act
         or the Company is satisfied that an exemption from such registration
         is available.

         SECTION 7.   Amendment and Termination.

         Except to the extent prohibited by applicable law or the rules of the
principal securities market on which the shares are traded and unless otherwise
expressly provided in an Option 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
         Option, or other Person.

             (ii) Amendments to Options. The Committee may waive any conditions
         or rights under, amend any terms of, or alter any Option theretofore
         granted, provided no change, other than pursuant to Section 7(iii), in
         any Option shall materially reduce the benefit to Participant without
         the consent of such Participant.

             (iii) Adjustment of Options Upon the Occurrence of Certain Unusual
         or Nonrecurring Events. The Committee is hereby authorized to make
         adjustments in the terms and conditions of, and the criteria included
         in, Options in recognition of unusual or nonrecurring events
         (including, without limitation, the events described in Section 4(c)
         of the Plan) affecting the Company, any Affiliate, or the financial
         statements of the Company or any Affiliate, or of changes in
         applicable laws, regulations, or accounting principles, whenever the
         Committee determines that such adjustments are appropriate in order to
         prevent dilution or enlargement of the benefits or potential benefits
         intended to be made available under the Plan.

         SECTION 8.   Change in Control.

         Notwithstanding any other provision of this Plan or an Option
agreement to the contrary, in the event of a Change in Control of the Company
all outstanding Options automatically shall become fully vested immediately
prior to such Change in Control (or such earlier time as set by the Committee).
For purposes of this Plan, a "Change in Control" shall be deemed to occur if:

             (i) any person, entity or group (as such terms are used in
         Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as
         amended (the "Act")), other than persons and entities which owned any
         capital stock of the Company on the closing date of the transactions
         contemplated in the acquisition agreements between the Company and
         certain other entities dated February 11, 1999, the Company or a
         subsidiary (the "AmPaM Companies") or an employee benefit plan of the
         AmPaM Companies, acquires, directly or indirectly, the beneficial
         ownership (as defined in Section 13(d) of the Act) of any voting
         security of the Company and immediately after such acquisition such
         person, entity or group is, directly or indirectly, the beneficial
         owner of voting securities representing 20% or more of the total
         voting power of all of the then


                                      -6-

<PAGE>   7


         outstanding voting securities of the Company entitled to vote
         generally in the election of directors;

             (ii) upon the first purchase of the Company's common stock
         pursuant to a tender or exchange offer (other than a tender or
         exchange offer made by the Company);

             (iii) 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 75% of the
         total voting power represented by the voting securities of the
         surviving entity outstanding immediately after such transaction being
         beneficially owned by the holders of all of the 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;

             (iv) the stockholders of the Company shall approve a plan of
         complete liquidation or dissolution of the Company or an agreement for
         the sale or disposition by the Company of all or substantially all of
         the Company's assets; or

             (v) if, at any time during any period of two consecutive years,
         individuals who at the beginning of such period constitute the Board
         cease for any reason to constitute at least a majority thereof, unless
         the election or nomination for the election by the Company's
         stockholders of each new director was approved a vote of at least
         two-thirds of the directors then still in office who were directors at
         the beginning of the period.

         In the event of a Change in Control, the Committee, in its discretion,
may (i) provide for the purchase of the Option for an amount of cash or other
property that could have been received upon the exercise of the Option, (ii)
adjust the terms of the Option in a manner determined by the Committee to
reflect the Change in Control, (iii) cause the Option to be assumed, or new
rights substituted therefor, by another entity, or (iv) make such other
provision as the Committee may consider equitable and in the best interests of
the Company, including, without limitation, providing for the termination of
the Option to the extent not exercised.

        SECTION 9.   General Provisions.

         (a) No Rights to Options. No Employee, Consultant or Director shall
have any claim to be granted any Option, and there is no obligation for
uniformity of treatment of Participants. The terms and conditions of Options
need not be the same with respect to each recipient.

         (b) No Right to Employment. The grant of an Option 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


                                      -7-

<PAGE>   8


liability or any claim under the Plan, unless otherwise expressly provided in
the Plan or in any Option Agreement.

         (c) 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 Texas and applicable federal law.

         (d) Severability. If any provision of the Plan or any Option is or
becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction or as to any Person or Option, or would disqualify the Plan or any
Option 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 Option, such
provision shall be stricken as to such jurisdiction, Person or Option and the
remainder of the Plan and any such Option shall remain in full force and
effect.

         (e) Other Laws. The Committee may refuse to issue or transfer any
Shares or other consideration under an Option 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.

         (f) No Trust or Fund Created. Neither the Plan nor the Option 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 Option, such right
shall be no greater than the right of any general unsecured creditor of the
Company or any Affiliate.

         (g) No Fractional Shares. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Option, 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.

         (h) 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.

        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 Option shall be granted under the Plan after the 10th anniversary
of the date the Plan is adopted by the Board. However, unless otherwise
expressly provided in the Plan or in an applicable Option agreement, any Option
granted prior to such termination, and the authority of the Board or


                                      -8-

the Committee to amend, alter, adjust, suspend, discontinue, or terminate any
such Option or to waive any conditions or rights under such Option, shall
extend beyond such termination date.

            TRANSFER RESTRICTION AND EXPENSE REIMBURSEMENT AGREEMENT


         For good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, American Plumbing & Mechanical, Inc., a Delaware
corporation (the "Company") and the undersigned, being stockholders of the
Company (the "Undersigned") hereby agree as follows:

1.       TRANSFER RESTRICTIONS

         1.1 TRANSFER RESTRICTIONS. For a period of two years from the date of
issuance or, in the event that the Company completes a firm commitment
underwritten initial public offering of shares of stock of the Company managed
by one or more nationally recognized national investment banking firms (an
"IPO"), for a period through the second anniversary of the date of the closing
of such IPO (the "Restricted Period"), the Undersigned shall not (i) sell,
assign, exchange, transfer, pledge, or otherwise dispose of any shares of
restricted common stock or common stock of the Company (the "Stock") currently
owned or held by the Undersigned or any securities convertible into,
exchangeable or exercisable for any shares of Stock, (ii) grant any option to
purchase, or otherwise enter into any contract to sell, assign, transfer,
pledge or otherwise dispose of, any shares of Stock currently owned or held by
the Undersigned, or (iii) enter into any swap or any other agreement or any
transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of any currently owned or held Stock, whether
any such swap or transaction is to be settled by delivery of shares of Stock or
other securities, by the delivery or payment of cash or otherwise, except, in
the case of clauses (i), (ii) or (iii) above, (A) as otherwise agreed by the
Company, (B) for the sale of shares of Stock, and entering into agreements
relating to the sale of shares of Stock, pursuant to Section 3 hereof, (C) for
transfers to (I) immediate family members of the Undersigned or to equity
owners or members of the Undersigned who agree with the Company in writing to
be bound by the restrictions set forth in this Section 1.1, (II) trusts,
limited partnerships or other estate planning entities for the benefit of the
Undersigned or family members of the Undersigned which have agreed with the
Company in writing, through action taken by the trustees, partners or other
persons having authority to bind the trust, limited partnership or other estate
planning entity, to be bound by the restrictions set forth in this Section 1.1,
(III) any charitable organization that qualifies for receipt of charitable
contributions under Section 170(c) of the Code which agrees with the Company in
writing to be bound by the restrictions set forth in this Section 1.1, (D) the
sale by the Undersigned in an IPO of shares of Stock, provided that if the
Company 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 Section 3.1 that the number of shares to be sold
by persons other than the Company is greater than the number of such shares
which can be offered without adversely affecting the success of the offering,
the Company may reduce pro rata (among the Undersigned and all other selling
security holders in the offering) 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. During the Restricted
Period, the certificates evidencing the Stock owned or held by the Undersigned
will bear a legend substantially in the form set forth below:


                                      -1-

<PAGE>   2


THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF WITHOUT THE WRITTEN
CONSENT OF THE COMPANY, AND THE COMPANY SHALL NOT BE REQUIRED TO GIVE EFFECT TO
ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION
PRIOR TO EXPIRATION OF TWO YEARS. SUCH RESTRICTIONS ON TRANSFER ARE SET FORTH
IN A TRANSFER RESTRICTION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE COMPANY. UPON THE WRITTEN REQUEST OF THE HOLDER OF
THIS CERTIFICATE, THE COMPANY AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY
STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE SPECIFIED ABOVE.

2.       FEDERAL SECURITIES ACT REPRESENTATIONS

         2.1 COMPLIANCE WITH LAW. The Undersigned acknowledges that the shares
of Stock have not been and will not be registered under the Securities Act of
1933, as amended (the "1933 Act") (except as provided in Section 3 hereof) and
therefore may not be sold, assigned, exchanged, transferred, pledged or
otherwise disposed of without compliance with the 1933 Act which, among other
matters, would require registration under the 1933 Act unless exemption from
the registration requirements is available for such transaction. The Stock was
being acquired solely for the Undersigned's own account, for investment
purposes only, and with no present intention of selling, assigning, exchanging,
transferring, pledging, or otherwise disposing of it. The Undersigned
covenants, warrants and represents that neither the shares of Stock issued to
the Undersigned was offered, sold, assigned, exchanged, pledged, 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
certificates representing the Stock shall bear the following legend in addition
to the legend required under Section 1 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 FEDERAL AND STATE SECURITIES LAWS.

3.       REGISTRATION RIGHTS

         3.1 PIGGYBACK REGISTRATION RIGHTS. At any time following the date
hereof, whenever the Company proposes to register any Stock for its own or
other's 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 the Company and (ii) registrations
relating to employee benefit plans, the Company shall give the Undersigned
prompt written notice of its intent to do so. Upon the written request of the
Undersigned given within 15 calendar days after receipt of such notice,
notwithstanding the provisions of Section 1 (except as specified below with
respect to an IPO), the Company shall cause to be included in such registration
all of the Stock held or owned by


                                      -2-

<PAGE>   3


the Undersigned (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 the Company as a stock split, dividend or other distribution with
respect to, or in exchange for, or in replacement of such Stock) which the
Undersigned requests, other than shares of Stock which may then be immediately
sold under Rule 144(k) (or any similar or successor provision) promulgated
under the 1933 Act, and other than shares of Stock that have been theretofore
sold by the Undersigned in accordance with the 1933 Act. In addition, if the
Company 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 3.1 that the number of shares to be
sold by persons other than the Company is greater than the number of such
shares which can be offered without adversely affecting the success of the
offering, the Company may reduce pro rata (among the Undersigned and all other
selling security holders in the offering) 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. If the
Undersigned disapproves of the terms of the underwriting, the Undersigned may
elect to withdraw therefrom by written notice to the Company and the managing
underwriter. The Undersigned's shares of Stock so withdrawn shall also be
withdrawn from registration.

         3.2 REGISTRATION PROCEDURES. Whenever the Company is required to
register shares of Stock pursuant to Section 3.1, the Company will, as
expeditiously as possible:

             (i) Prepare and file with the Securities and Exchange Commission
         (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,
         the Company will furnish a representative of the Undersigned with
         copies of all such documents proposed to be filed) as promptly as
         practical;

             (ii) Notify the Undersigned of any stop order issued or threatened
         by the SEC and take all reasonable actions required to prevent the
         entry of such stop order or to remove it if entered;

             (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth
         in such registration statement or supplement to the prospectus;

             (iv) Furnish to the Undersigned upon request such number of copies
         of such registration statement, each amendment and supplement thereto
         and the prospectus included

                                      -3-

<PAGE>   4



         in such registration statement (including each preliminary prospectus
         and any term sheet associated therewith), and such other documents as
         the Undersigned may reasonably request in order to facilitate the
         disposition of the relevant shares;

             (v) Make "generally available to its security holders" (within the
         meaning of Rule 158) an earnings statement satisfying the provisions
         of Section 11(a) of the 1933 Act and Rule 158 thereunder no later than
         90 days after the end of the 12-month period beginning with the first
         day of the Company's first fiscal quarter commencing after the
         effective date of the registration statement;

             (vi) Make every reasonable effort to obtain the withdrawal of any
         order suspending the effectiveness of the registration statement at
         the earliest possible moment;

             (vii) If requested by the managing underwriter or underwriters, if
         any, or any participating stockholder, promptly incorporate in a
         prospectus supplement or post-effective amendment such information as
         the managing underwriter or underwriters or any participating
         stockholder, as the case may be, reasonably requests to be included
         therein, including, without limitation, information with respect to
         the number of shares of Stock being sold by participating stockholders
         to any underwriter or underwriters, the purchase price being paid
         therefor by such underwriter or underwriters and with respect to any
         other terms of an underwritten offering of the shares of Stock to be
         sold in such offering, and promptly make all required filings of such
         prospectus by supplement or post-effective amendment;

             (viii) Make available for inspection by participating
         stockholders, any underwriter participating in any disposition
         pursuant to such registration statement, and the counsel retained by
         the participating stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating stockholders or
         any such underwriter (collectively, the "Inspectors"), all financial
         and other records, pertinent corporate documents and properties of the
         Company (the "Records"), as shall be reasonably necessary to enable
         them to exercise their due diligence responsibility, and cause the
         Company's officers, directors and employees to supply all information
         reasonably requested by any such Inspectors in connection with such
         registration statement; provided, that records which the Company
         determines, in good faith, to be confidential and which the Company
         notifies the Inspectors are confidential shall not be disclosed by the
         Inspectors unless (i) the disclosure of such Records is necessary to
         avoid or correct a misstatement or omission in the registration
         statement or (ii) the release of such Records is ordered pursuant to a
         subpoena or other order from a court of competent jurisdiction after
         delivery of sufficient notice to the Company to enable the Company to
         contest such subpoena or order;

             (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of Stock contemplated hereby;


                                      -4-

<PAGE>   5


             (x) 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 Undersigned, and to keep such registration or qualification
         effective during the period such registration statement is required to
         be kept effective, provided that the Company shall not be required to
         become subject to taxation, to qualify generally to do business or to
         file a general consent to service of process in any such states or
         jurisdictions;

             (xi) Cause all such shares of Stock to be listed or included not
         later than the date of the first sale of shares of Stock under such
         registration statement on any securities exchanges or trading systems
         on which similar securities issued by the Company are then listed or
         included; and

             (xii) Notify the Undersigned at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that the Company 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 (as then in
         effect), together with any associated term sheet, contains an untrue
         statement of a material fact or omits to state any fact required to be
         stated therein or necessary to make the statements therein (in the
         case of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading, and, at the
         request of the Undersigned, the Company promptly 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 required to be stated therein or necessary to make the
         statements therein (in the case of the prospectus or any preliminary
         prospectus, in light of the circumstances under which they were made)
         not misleading.

         All expenses incurred in connection with the registration under this
Article 3 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall
be borne by the Company.

         3.3      INDEMNIFICATION.

                  (a) In connection with any registration under Section 3.1,
the Company shall indemnify, to the extent permitted by law, the Undersigned
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue
statement of material fact contained or incorporated by reference in any
registration statement, prospectus or preliminary prospectus or associated term
sheet or any omission or alleged omission to state or incorporated by reference
therein a material fact required to be stated or incorporated by reference
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 the Company by such Indemnified Party
expressly for use therein or by any Indemnified Parties' failure

                                      -5-

<PAGE>   6


to deliver a copy of the registration statement or prospectus or any amendment
or supplements thereto after the Company has furnished such Indemnified Party
with a sufficient number of copies of the same.

                  (b) In connection with any registration under Section 3.1,
the Undersigned shall furnish to the Company in writing such information
concerning the Undersigned and his or her proposed offering of shares as is
reasonably requested by the Company for use in any such registration statement
or prospectus and will indemnify, to the extent permitted by law, the Company,
its directors and officers and each person who controls the Company (within the
meaning of the 1933 Act) against any losses, claims, damages, liabilities and
expenses resulting from any untrue or alleged untrue statement of a material
fact or any omission or alleged omission to state therein a material fact
required to be stated in the registration statement or prospectus or any
amendment thereof or supplement thereto or necessary to make the statements
therein not misleading, but only to the extent that such untrue or alleged
untrue statement or omission or alleged omission is contained in or omitted
from information so furnished in writing to the Company by the Undersigned
expressly for use in the registration statement. Notwithstanding the foregoing,
the liability of the Undersigned under this Section 3.3 shall be limited to an
amount equal to the net proceeds actually received by the Undersigned from the
sale of the relevant shares covered by the registration statement.

                  (c) Any person entitled to indemnification hereunder 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 that 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.

         3.4 UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Section 3.1 covering an underwritten registered offering, (i) the
Undersigned shall execute and deliver to the Company a written power of
attorney instrument that (A) appoints an officer of the Company as the
Undersigned's attorney-in-fact for purposes of executing and delivering an
underwriting agreement among the Company, the underwriters named therein and
the Undersigned specifying the terms and conditions applicable to the sale of
Stock of the Undersigned in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering

                                      -6-

<PAGE>   7


in which one or more stockholders of the issuer are participants, including a
provision that authorizes the attorney-in-fact appointed by the Undersigned to
execute and deliver such an underwriting agreement in the event that the net
price per share to be received by the Undersigned from the sale of the shares
of Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) the Company and the Undersigned 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 the Company's
size and investment stature, including indemnification; provided, however, that
(A) the Undersigned shall be exempt and excluded from any indemnification of
the managing underwriters other than with respect to information provided by
the Undersigned with respect to the Undersigned to the Company or the managing
underwriters specifically for inclusion in any such registration statement and
(B) the Undersigned shall not be obligated to enter into such an underwriting
agreement in the event that the net price per share to be received by the
Undersigned from the sale of shares of Stock to be sold in such offering is
less than the floor price specified in the power of attorney instrument
executed and delivered to the Company pursuant to clause (i) above.

         3.5 TRANSFER OF RIGHTS. The right to cause the Company to register
shares of Stock under this Agreement may be assigned to a transferee or
assignee of the Undersigned to the extent that such transferee or assignee is a
member of the immediate family of the Undersigned, a trust, limited partnership
or other estate planning entity for the benefit of any such persons or a
charitable organization that qualifies for receipt of charitable contributions
under Section 170(c) of the Code.

         3.6 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 stock
to the public without registration, following an IPO the Company agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

             (i) make and keep public information regarding the Company
         available as those terms are understood and defined in Rule 144 under
         the 1933 Act beginning 90 days following the effective date of a
         registration statement relating to an IPO;

             (ii) file with the SEC in a timely manner all reports and other
         documents required of the Company 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 the Undersigned owns any restricted Stock,
         furnish to the Undersigned forthwith upon written request a written
         statement by the Company as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 the Company, and such other
         reports and documents so filed as the Undersigned may reasonably
         request in availing itself of any rule or regulation of the SEC
         allowing the Undersigned to sell any such shares without registration.

         Except as otherwise qualified below, AmPaM represents and warrants that
all of the following representations and warranties in this Section 6 are true
at the date of this Agreement and, subject to Section 7.7 hereof, shall be true
at the time of Closing, and that such representations and warranties shall
survive the Closing Date for a period of eighteen months (the last day of such
period being the "Expiration Date" for purposes of the representations and
warranties set forth in this Section 6), except that the representations and
warranties set forth in Section 6.3, 6.11 and 6.15 shall survive until such time
as the applicable statute of limitations period has run, which shall be deemed
to be the Expiration Date for the representations and warranties set forth in
Sections 6.3, 6.11 and 6.15.

         AmPaM acknowledges that in purchasing the shares of Company Stock, it
is relying upon its own independent investigation as well as the representations
and warranties of the Company and the Stockholders as set forth in this
Agreement.

         6.1 DUE ORGANIZATION. AmPaM is a corporation duly incorporated and
organized, validly existing and in good standing under the laws of the State of
Delaware, and has the requisite power and authority to carry on its business as
it is now being conducted and as contemplated by the Private Placement
Memorandum. AmPaM is duly qualified or authorized to do business and is in good
standing in each jurisdiction in which the nature of its business or the
ownership or leasing of its properties makes such qualification or authorization
necessary, except where the failure to be so qualified or authorized to do
business would not have a Material Adverse Effect. True, complete and correct
copies of the Certificate of Incorporation and By-laws, each as proposed to be
amended and as such documents shall be in effect as of the Closing Date, of
AmPaM (the "AmPaM Charter Documents") are attached hereto as Annex II.

         6.2 AUTHORIZATION. (i) The officers of AmPaM executing this Agreement
have the authority to enter into and bind AmPaM to the terms of this Agreement
and (ii) AmPaM has the full legal right, power and authority to enter into this
Agreement and consummate the transactions contemplated hereby. All corporate
acts and other proceedings required to have been taken by AmPaM to authorize the
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby have been duly and properly taken.

         6.3 CAPITAL STOCK OF AMPAM. The authorized capital stock of AmPaM is as
set forth in Section 1.3(ii). Immediately prior to the Closing Date, all of the
issued and outstanding shares of the capital stock of AmPaM will be as set forth
in the Private Placement Memorandum, free and clear of all liens, security
interests, pledges, charges, voting trusts, restrictions, encumbrances and
claims of every kind other than any restrictions described in the Private
Placement Memorandum. All of the issued and outstanding shares of the capital
stock of AmPaM have been duly authorized and validly issued, are fully paid and
nonassessable and such shares were offered, issued, sold and delivered by AmPaM
in compliance with all applicable state and Federal laws concerning the issuance
of securities. Further, none of such shares were issued in violation of the
preemptive rights


                                       24

<PAGE>   33


of any past or present stockholder of AmPaM. Upon the Closing Date, the
authorized, issued and outstanding shares of capital stock of AmPaM will be as
set forth in the Private Placement Memorandum under the caption
"Capitalization." Upon the Closing Date, the aggregate number of shares of AmPaM
Stock issued and outstanding on the Closing Date that are owned by Sterling City
Capital, LLC, any Affiliates of Sterling City Capital, LLC and the officers and
directors of AmPaM will not be greater than the number of shares of AmPaM Stock
reflected in the Private Placement Memorandum as the aggregate number of shares
of AmPaM Stock to be issued and outstanding and owned by Sterling City Capital,
LLC, any Affiliates of Sterling City Capital, LLC and the officers and directors
of AmPaM.

         6.4 TRANSACTIONS IN CAPITAL STOCK. Except as set forth in this
Agreement, the Other Agreements and except as set forth in the Private Placement
Memorandum, (i) no option, warrant, call, conversion right or commitment of any
kind exists as of the date of this Agreement which obligates AmPaM to issue any
of its authorized but unissued capital stock; and (ii) AmPaM has no obligation
(contingent or otherwise) to purchase, redeem or otherwise acquire any of its
equity securities or any interests therein or to pay any dividend or make any
distribution in respect thereof. The material terms of any options, warrants or
other rights to acquire shares of the stock of AmPaM referred to in the
preceding sentence will be as described in the Private Placement Memorandum.

         6.5 SUBSIDIARIES. As of the date of this Agreement, AmPaM has no
subsidiaries. As of the date of this Agreement, AmPaM does not own, of record or
beneficially, or control, directly or indirectly, any capital stock, securities
convertible into capital stock or any other equity interest in any corporation,
association or business entity, and AmPaM is not, directly or indirectly, a
participant in any joint venture, partnership or other non-corporate entity.

         6.6 FINANCIAL STATEMENTS. The historical financial statements of AmPaM
included in the Private Placement Memorandum (the "AmPaM Financial Statements")
have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods indicated (except as noted thereon), and the balance
sheet included therein presents fairly the financial position of AmPaM as of its
date. Management of AmPaM believes that the assumptions underlying the pro forma
adjustments utilized in the preparation of such pro forma financial statements
are reasonable, and such pro forma adjustments have been properly applied to the
historical financial amounts in the compilation of the pro forma financial
statements. Based on the representations in Section 5.9 of this Agreement and in
Section 5.9 of each of the Other Agreements, the pro forma financial information
of AmPaM fairly presents the pro forma financial position, results of operations
and other information purported to be shown therein at the respective dates and
for the respective periods specified.

         6.7 LIABILITIES AND OBLIGATIONS. Except as set forth in the Private
Placement Memorandum, as of the date of this Agreement, AmPaM has no material
liabilities or obligations of any kind, character or description, whether
accrued, absolute, secured or unsecured, contingent or otherwise, other than
liabilities incurred in the ordinary course of business and consistent with past
practices, liabilities or obligations set forth in or contemplated by this
Agreement and the Other

actions, suits or proceedings, pending or, to the knowledge of AmPaM, threatened

all material respects with the requirements, standards, criteria and conditions
set forth in applicable Federal, state and local statutes, ordinances, permits,

Tax liabilities payable by any of the Stockholders for periods ending on or
prior to the Closing Date.

                  (d) Each party hereto shall, and shall cause its subsidiaries
and Affiliates to, provide to each of the other parties hereto such cooperation
and information as any of them reasonably may request in 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 audit or other proceeding in respect of
Taxes. Such cooperation and information shall include providing copies 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.
Subject to the preceding sentence, each party required to file Returns pursuant
to this Agreement shall bear all costs of filing such Returns.

                  (e) Each of the Company, AmPaM and each Stockholder shall
comply with the tax reporting requirements of Section 1.351-3 of the 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.

         10.4 DIRECTORS. The persons named in the Private Placement Memorandum
shall be appointed as directors and elected as officers of AmPaM, as and to the
extent set forth in the Private Placement Memorandum, promptly following the
Closing Date; provided, however, that the parties hereto acknowledge that if the
Company consummates an IPO, the persons who will serve as directors and
executive officers of AmPaM will be adjusted as appropriate for a publicly
traded entity, with any such changes being subject to the approval of the
majority of the Board of Directors of AmPaM.

         10.5 LEGAL OPINIONS. If required by the lenders pursuant to the terms
of any agreements related to financing of the cash amounts referred to in
Section 9.11 hereof, the Company shall cause its counsel to deliver to such
lenders, at the Closing, an opinion of counsel in substantially the form
attached hereto as Annex V.

11.      INDEMNIFICATION

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

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 AmPaM as a result of
or arising from (i) any breach of the representations and warranties of the

writing by the Company specifically for inclusion in the Private Placement
Memorandum and is contained in the Private Placement Memorandum, 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 required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that no Stockholder shall be liable
for any indemnification obligation pursuant to this Section 11.1 in excess of
such Stockholder's pro rata share thereof determined by reference to the
aggregate value of the Base Cash Amount (as defined in Annex I of this
Agreement), the principal amount of AmPaM Notes, the shares of AmPaM Series A
Preferred Stock (valued at a stated value of $13.00 per share) and the shares of
AmPaM Stock (valued at a price of $13.00 per share) received by such Stockholder
pursuant to Section I.A. of Annex I hereto (without giving effect to the
adjustments provided in Sections I.B. and I.C. thereof) (giving effect to the
value of such AmPaM Stock and such AmPaM Series A Preferred Stock and without
giving effect to such adjustments, collectively, the "Aggregate Consideration")
such Stockholder would receive pursuant to Section I of Annex I of this
Agreement if the transactions contemplated hereby were consummated in relation
to the total Aggregate Consideration all Stockholders would receive pursuant to
Section I of Annex I of this Agreement if the transactions contemplated hereby
were consummated.

         (b) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement, from and against all claims, damages, actions,

any breach of the representations and warranties of such Stockholder set forth
in Section 5(B) hereof, (ii) any breach of any covenant or agreement on the part
of such Stockholder under this Agreement, or (iii) any liability under the 1933
Act or any Federal or state securities 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 solely to such Stockholder which was based
upon information provided to AmPaM or


                                       41

<PAGE>   50


its counsel in writing by such Stockholder specifically for inclusion in the
Private Placement Memorandum and is contained in the Private Placement
Memorandum, 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 solely to such Stockholder required to be stated therein or necessary
to make the statements therein in light of the circumstances in which such
statements were made not misleading.

         (c) AmPaM acknowledges and agrees that other than the representations
and warranties of the Company or the Stockholders specifically contained in this
Agreement, there are no representations or warranties of the Company or the
Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

         11.2 INDEMNIFICATION BY AMPAM. AmPaM covenants and agrees that it will
indemnify, defend, protect and hold harmless the Company and the Stockholders at
all times from and after the date of this Agreement until the applicable
Expiration Date (as defined in the introductory paragraph of Section 6, provided
that for purposes of clause (iii) below, the applicable 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 the
Company or the Stockholders as a result of or arising from (i) any breach by
AmPaM of its representations and warranties set forth herein or on the schedules
attached hereto or certificates delivered pursuant to this Agreement, (ii) any
breach of any agreement on the part of AmPaM under this Agreement; or (iii) any
liability under the 1933 Act or any Federal or state securities 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 contained in the
Private Placement Memorandum, 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 required to be stated therein or necessary to make the statements
therein not misleading, except to the extent such is based upon an untrue
statement or alleged untrue statement, or omission or alleged omission, made
therein in reliance upon, and in conformity with, the representations and
warranties of the Company or the Stockholders specifically contained in this
Agreement or other information furnished to AmPaM by the Company or the
Stockholders in writing specifically for inclusion therein.

         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, 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 reasonably
satisfactory to the


                                       42

<PAGE>   51


Indemnified Party, 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 or a conflict of interest is reasonably likely to
arise that prevents counsel for the Indemnifying Party from representing such
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, 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. 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 pay the
Indemnified Party for the settlement amount 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. With respect to any account, note or other
receivable as to which the Stockholders have paid in full any indemnification
obligation pursuant to this Section 11 as a result of a breach of the
representation and warranty made pursuant to Section 5.11 or as to which a claim
in respect thereof has been asserted pursuant to this Section 11 that has been
applied against the Indemnification Threshold with respect to the Stockholders
as a result of a breach of the representation and warranty made pursuant to
Section 5.11, AmPaM shall cause the Company to assign such account, note or
other receivable to


                                       43

<PAGE>   52


the Stockholders. 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. 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 to this Agreement with respect to any
provision of this Agreement, provided that, nothing herein shall be construed to
limit the right of a party, in a proper case, to seek injunctive relief for a
breach of this Agreement. AmPaM hereby waives, to the fullest extent permitted
under applicable law, any and all other rights, claims and causes of action,
known or unknown, it or any indemnified person may have against the Company or
any Stockholder relating to this Agreement or the transactions pursuant to this
Agreement arising under or based upon any Federal, state, local or foreign
statute, law, rule, regulation or otherwise. 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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2 (calculated as provided in this Section 11.5) plus (iii) the
principal amount of the AmPaM Notes delivered to the Stockholders pursuant to
Section 1.2 (iv) plus the value of the AmPaM Series A Preferred Stock delivered
to the Stockholders pursuant to Section 1.2 (calculated as provided in this
Section 11.5), or (b) $50,000 (the "Indemnification Threshold"). Stockholders
shall not assert any claim for indemnification hereunder against AmPaM until
such time as, and solely to the extent that, the aggregate of all claims which
Stockholders may have against AmPaM shall exceed $50,000; provided, however,
that this sentence shall not be applicable with respect of any failure by AmPaM
to (i) deliver the consideration specified in Annex I hereto on the Closing Date
upon the satisfaction, or waiver by AmPaM, of all conditions to the occurrence
of the Closing Date specified in Section 9 or (ii) comply with its obligations
pursuant to Section 10.1. After the $50,000 threshold for AmPaM (subject to the
proviso in the preceding sentence) or the Indemnification Threshold for a
Stockholder has been met, all claims must be made in $10,000 increments, which
claims may be cumulated in order to meet such $10,000 thresholds. For purposes
of this paragraph, the AmPaM Stock delivered to the Stockholders shall be valued
at $13.00 per share and the AmPaM Series A Preferred Stock delivered to the
Stockholders shall have a stated value of $13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is directly
or indirectly related to a breach by such person of any representation,
warranty, covenant or other agreement set forth in this Agreement.


                                       44

<PAGE>   53


No claim for indemnification against the Stockholders shall limit, diminish or
change any obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at $13.00
per share and the AmPaM Series A Preferred Stock delivered to the Stockholders
shall have a stated value of $13.00 per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock or shares of AmPaM Series A Preferred Stock;
provided that the percentage of the indemnification obligation satisfied by
means of the delivery of shares of AmPaM Stock or shares of AmPaM Series A
Preferred Stock does not exceed the percentage of AmPaM Stock or shares of AmPaM
Series A Preferred Stock comprising the total consideration paid to such
Stockholder by AmPaM to such Stockholder pursuant to Annex I. For the purpose of
crediting Stockholders for payments made to AmPaM by means of delivery of shares
of AmPaM Stock or shares of AmPaM Series A Preferred Stock, the AmPaM Stock
shall be valued at $13.00 per share and the AmPaM Series A Preferred Stock
delivered to the Stockholders shall have a stated value of $13.00 per share.

         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary of
AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM shall use commercially reasonable
efforts to pursue any available insurance coverage or other rights of indemnity
or reimbursement from third parties with respect to any such loss, liability or
expense.

12.      TERMINATION OF AGREEMENT

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

                  (i) by mutual consent of AmPaM and the Stockholders;

                  (ii) by the Stockholders, if the transactions contemplated by
         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by the Company
         or the Stockholders prior to or on the Closing Date;


                                       45

<PAGE>   54


                  (iii) by AmPaM, if the transactions contemplated by this
         Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by AmPaM prior
         to or on the Closing Date;

                  (iv) by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein
         relating to AmPaM, and the curing of such default shall not have been
         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v) by AmPaM, if a material breach or default shall be made by
         the Company or the Stockholders in the observance or in the due and
         timely performance of any of the covenants or agreements contained
         herein relating to the Company or the Stockholders, and the curing of
         such default shall not have been made (or in the reasonable judgment of
         AmPaM cannot be made) on or before the Closing Date;

                  (vi) by the Stockholders, if the conditions set forth in
         Section 8 hereof have not been satisfied or waived as of the Closing
         Date; or

                  (vii) by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2 PROCEDURE AND EFFECT OF TERMINATION. A determination to terminate
this Agreement by AmPaM pursuant to Section 12.1 shall be valid and effective
only if a written notice of termination, accompanied by a certified copy of
resolutions of the board of directors of AmPaM that evidence the authorization
of the officer of AmPaM to deliver a written notice of termination of this
Agreement pursuant to Section 12.1, is given to the Stockholders in the manner
specified for notices in this Agreement. A determination to terminate this
Agreement by the Stockholders pursuant to Section 12.1 shall be valid and
effective only if a written notice of termination, signed by Stockholders who
would be entitled to receive a majority of the shares of AmPaM Stock and AmPaM
Series A Preferred Stock specified in Section I of Annex I to this Agreement if
the transactions contemplated hereby were consummated, is given to AmPaM in the
manner specified for notices in this Agreement. Upon the giving of notice of
termination of this Agreement pursuant to Section 12.1 as specified in the
preceding sentence, this Agreement shall terminate, and the transactions
contemplated hereby shall be abandoned, without further action by any of the
parties hereto. Immediately upon any such termination, AmPaM shall deliver
written notice of such termination to the Other Founding Companies. If this
Agreement is terminated as provided in this Section 12, no party hereto shall
have any liability or further obligation hereunder to any other party, except as
provided in Section 14 and Section 18.6, provided, that, 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


                                       46

<PAGE>   55


contained in this Agreement including, but not limited to, legal and audit costs
and out of pocket expenses that occurred prior to such termination.

13.      NONCOMPETITION

         13.1 PROHIBITED ACTIVITIES. The Stockholders will not, without the
prior written consent of AmPaM, for a period of two (2) years following the
Closing 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) 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, whether paid or unpaid, in any plumbing, piping,
         mechanical, heating, ventilation or air conditioning contracting,
         installation or services business or operation, whether for
         residential, commercial, industrial or governmental customers, or any
         ancillary contracting, installation or services business directly
         related thereto (such business and operations referred to herein as the
         "Plumbing and Mechanical Business"), within 100 miles of where the
         Company or any of its subsidiaries conducted business within two (2)
         years prior to the Closing Date (the "Territory");

                  (ii) call upon any person who is, at the Closing Date, within
         the Territory, an employee of AmPaM or any subsidiary thereof for the
         purpose or with the intent of enticing such employee away from or out
         of the employ of AmPaM or any subsidiary thereof;

                  (iii) call upon any person or entity which is, at the Closing
         Date, or which has been within three (3) years prior to the Closing
         Date, a customer of AmPaM or any subsidiary thereof, of the Company or
         of any of the Other Founding Companies for the purpose of soliciting
         customers, orders or contracts for any Plumbing and Mechanical Business
         in direct competition with AmPaM within the Territory;

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

                  (v) disclose to any person, firm, partnership, corporation or
         business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or any
         of its subsidiaries within the two (2) years prior to the Closing Date
         for any reason or purpose whatsoever except to the extent that the
         Company has in the past disclosed such information to the public for
         valid business reasons; or


                                       47
<PAGE>   56


                  (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition. In addition, the provisions of
clause (i) above shall not apply to George Christianson with respect to the
heating, ventilation and air conditioning installation and service business.

         13.2 DAMAGES. Because of the difficulty of measuring economic losses to
AmPaM as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to AmPaM for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by AmPaM 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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by AmPaM of such
covenants. It is specifically agreed that the period of two (2) 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
found to be in violation of any provision of this Section 13 as determined by
any of (i) a written agreement to such effect executed and delivered by AmPaM
and such Stockholder, (ii) a determination by an arbitration panel pursuant to
an arbitration conducted pursuant to Section 18.16 hereof or (iii) a
non-appealable judgment of a court of competent jurisdiction. The covenants
contained in Section 13 shall not be affected by any breach of any other


                                       48

<PAGE>   57


provision hereof by any party hereto. The covenants contained in Section 13
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
the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and pricing and cost
policies that are valuable, special and unique assets of the Company's, the
Other Founding Companies' and/or AmPaM'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 AmPaM, (b) following the
Closing, such information may be disclosed by the Stockholders as is required in
the course of performing their duties for AmPaM or the Company and (c) to its
counsel and other advisers, provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 14.1; provided, however
that (i) the foregoing disclosure prohibition shall not apply in the event that
(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 AmPaM and provide AmPaM 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, AmPaM 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 AmPaM 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 AMPAM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies that
are valuable, special and unique assets of the Company's business. AmPaM agrees
that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or

                                       49

<PAGE>   58


advisable in connection with the applicable securities laws; provided, however
that the foregoing disclosure prohibition shall not apply in the event that (A)
such information becomes known to the public generally through no fault of
AmPaM, (B) 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 (B), AmPaM 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 (C) 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 AmPaM of the provisions of this
Section 14.2, the Company and the Stockholders shall be entitled to an
injunction restraining AmPaM 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. In the event the
transactions contemplated by this Agreement are not consummated for any reason,
AmPaM shall nevertheless remain subject to this Section 14.2, except that it
shall not be permitted to make any disclosures otherwise than pursuant to clause
(A), (B) or (C) above.

         14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

         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 Closing Date.

         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AMPAM STOCK. For a period of two

transfer, pledge, or otherwise dispose of any shares of AmPaM Stock (including
shares received in a conversion of the AmPaM Series A Preferred Stock), AmPaM
Series A Preferred Stock or AmPaM Notes received by the Stockholders pursuant to

indirectly, the economic consequence of ownership of the AmPaM Stock, AmPaM

to be settled by delivery of shares of AmPaM Stock, AmPaM Notes or AmPaM Series
A Preferred Stock or other securities, by the delivery or payment of cash or
otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A) as
otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock, pursuant

another Stockholder, to another person or entity who receives shares of AmPaM

exempt from the registration requirements of the 1933 Act as evidenced by the
delivery to AmPaM of an opinion of counsel in form and substance reasonably
satisfactory to AmPaM and (2) any such transferee agrees in writing to be bound
by the restrictions set forth in this Section 15.1, (F) transfers of shares of
AmPaM Stock, shares of AmPaM Notes or AmPaM Series A Preferred Stock, or grants

AmPaM Series A Preferred Stock received by such Stockholder pursuant to this
Agreement provided that (1) any such transaction is exempt from the registration
requirements of the 1933 Act as evidenced by the delivery to AmPaM of an opinion

such employee agrees with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1, (G) the sale by such Stockholder in an IPO of shares
of AmPaM Stock representing not more than 10% of the Aggregate Consideration in
cash; provided, however, that in no circumstance will a Stockholder be entitled
to sell shares of AmPaM Stock in an IPO to the extent that the sale of such
shares by such Stockholder would result in such Stockholder receiving in excess
of 45% of the Aggregate Consideration in cash; and, provided further, if AmPaM
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 Section 17.1 that the number of shares to be sold
by persons other than AmPaM is greater than the number of such shares which can
be offered without adversely affecting the success of the offering, AmPaM may
reduce pro rata (among the Stockholders and all other selling security holders
in the offering) 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 or (H) pledges of AmPaM Stock, AmPaM
Series A Preferred Stock or AmPaM Notes to secure a bonafide financing
arrangement with an unaffiliated financial institution; provided that the party
to whom such securities are pledged agrees to be bound by the transfer
restrictions set forth in this Agreement. During the Restricted Period, the

                                       51

<PAGE>   60



Notes or the AmPaM Series A Preferred Stock delivered to the Stockholders
pursuant to Section 3 of this Agreement will bear a legend substantially in the
form set forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION
OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the shares
of AmPaM Stock, the shares of AmPaM Series A Preferred Stock, the Additional
Consideration Right and any AmPaM Notes to be delivered to such 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
sold, assigned, exchanged, transferred, pledged or otherwise disposed of without
compliance with the 1933 Act which, among other matters, would require
registration under the 1933 Act unless exemption from the registration
requirements is available for such transaction. The AmPaM Stock, the AmPaM
Series A Preferred Stock, the Additional Consideration Right and any AmPaM Notes
to be acquired by each Stockholder pursuant to this Agreement is being acquired
solely for such Stockholder's own account, for investment purposes only, and
with no present intention of selling, assigning, exchanging, transferring,
pledging, or otherwise disposing of it. Each Stockholder covenants, warrants and
represents that neither the shares of AmPaM Stock, the AmPaM Series A Preferred
Stock, the Additional Consideration Right nor any AmPaM Notes issued to such
Stockholder will be offered, sold, assigned, exchanged, pledged, transferred or
otherwise


                                       52

<PAGE>   61


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 certificates
representing the AmPaM Stock or the AmPaM Series A Preferred 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock, the AmPaM Series A
Preferred Stock and AmPaM Notes to be acquired pursuant to this Agreement and
can afford to sustain a total loss of such investment. Each Stockholder has
substantial knowledge and experience in making investment decisions of this type
(or is relying on qualified purchaser representatives with such knowledge and
experience in making this decision), and is capable, either individually or with
such purchaser representatives, of evaluating the merits and risks of this
investment. Each Stockholder has had an adequate opportunity to ask questions
and receive answers from the officers of AmPaM 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
AmPaM, the plans for the operations of the business of AmPaM, the business,
operations and financial condition of the Founding Companies other than the
Company, and any plans for additional acquisitions. Each Stockholder has asked
any and all questions of the nature described in the preceding sentence and all
questions have been answered to such Stockholder's satisfaction. Except as set
forth on Schedule 16.2, each Stockholder is an "accredited investor" as defined
in Rule 501(a) of the 1933 Act. Neither the foregoing nor any investigation made
by the Stockholders referred to above shall in any way affect the
representations, warranties, covenants and agreements of AmPaM made herein
except to the extent that AmPaM is relying upon the representations of the
Stockholders in Section 16.1 and in this Section 16.2 for purposes of AmPaM's
representations and warranties in Sections 6.9, 6.11, 6.15 and 6.17 hereof as
specified therein.

         16.3 RELIANCE BY AMPAM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock and the AmPaM
Series A Preferred Stock pursuant to this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to register
any AmPaM Stock for its own or other's 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 AmPaM and (ii)
registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such Stockholders pursuant to
this Agreement (including any stock issued as or issuable upon the conversion or
exchange of the AmPaM Series A Preferred Stock and any convertible security,
warrant, right or other security which is issued by AmPaM as a stock split,
dividend or other distribution with respect to, or in exchange for, or in
replacement of such AmPaM Stock or AmPaM Series A Preferred Stock) which any
such Stockholder requests, other than shares of AmPaM Stock which may then be
immediately sold under Rule 144(k) (or any similar or successor provision)
promulgated under the 1933 Act, and other than shares of AmPaM Stock that have
been theretofore sold by the Stockholder in accordance with the 1933 Act,
provided that AmPaM shall have the right to reduce pro rata the number of shares
of each selling Stockholder included in such registration to the extent that
inclusion of such shares would, in the written opinion of tax counsel to AmPaM
or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Private Placement Memorandum as a tax-free
organization under Section 351 of the Code; provided, however, that with respect
to a proposal by AmPaM to register AmPaM Stock under the 1933 Act in connection
with an IPO, no Stockholder shall be permitted pursuant to this Section 17.1 to
have included in such registration more shares of AmPaM Stock than permitted to
be sold by such Stockholder pursuant to Section 15.1. In addition, if AmPaM 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 AmPaM is greater than the number of such shares which can be offered
without adversely affecting the success of the offering, AmPaM may reduce pro
rata (among the Stockholders and all other selling security holders in the
offering) 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. If any Stockholder disapproves of the terms of the
underwriting, that Stockholder may elect to withdraw therefrom by written notice
to AmPaM and the managing underwriter. That Stockholder's shares of AmPaM Stock
so withdrawn shall also be withdrawn from registration; provided, however, that,
if by the withdrawal of such shares a greater number of shares of AmPaM Stock
held by other Stockholders may be included in such registration, then AmPaM
shall offer to all other Stockholders of AmPaM the right to include additional
shares in the same proportion used in effecting the above limitations. AmPaM
shall not, for a period of two years following the Closing Date, grant to any
other person any rights to cause AmPaM to register any securities in priority
over, or in precedent to, the rights granted to the Stockholders hereunder and
to the stockholders of the Other Founding Companies pursuant to Section 17 of
the Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a representative of the
         Stockholders with copies of all such documents proposed to be filed) as
         promptly as practical;

                  (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such registration statement or supplement to the prospectus;

                  (iv) 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;

                  (v) Make "generally available to its security holders" (within
         the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;

                  (vi) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of the registration statement at
         the earliest possible moment;

                  (vii) If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment such
         information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM


                                       55

<PAGE>   64


         Stock being sold by participating Stockholders to any underwriter or
         underwriters, the purchase price being paid therefor by such
         underwriter or underwriters and with respect to any other terms of an
         underwritten offering of the shares of AmPaM Stock to be sold in such
         offering, and promptly make all required filings of such prospectus by
         supplement or post-effective amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition pursuant
         to such registration statement, and the counsel retained by the
         participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or any
         such underwriter (collectively, the "Inspectors"), all financial and
         other records, pertinent corporate documents and properties of AmPaM
         (the "Records"), as shall be reasonably necessary to enable them to
         exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x) 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 required to
         be kept effective, provided that AmPaM shall not be required to become
         subject to taxation, to qualify generally to do business or to file a
         general consent to service of process in any such states or
         jurisdictions;

                  (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any securities exchanges or
         trading systems on which similar securities issued by AmPaM are then
         listed or included; and

                  (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in effect),
         together with any associated term sheet, contains an untrue statement
         of a material fact or omits to state any


                                       56

<PAGE>   65


         fact required to be stated therein or necessary to make the statements
         therein (in the case of the prospectus or any preliminary prospectus,
         in light of the circumstances under which they were made) not
         misleading, and, at the request of such Stockholder, AmPaM promptly
         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 required to be stated therein or necessary to
         make the statements therein (in the case of the prospectus or any
         preliminary prospectus, in light of the circumstances under which they
         were made) not misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall be
borne by AmPaM.

         17.3     INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue statement
of material fact contained or incorporated by reference in any registration
statement, prospectus or preliminary prospectus or associated term sheet or any
omission or alleged omission to state or incorporated by reference therein a
material fact required to be stated or incorporated by reference 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 AmPaM 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 AmPaM has furnished
such Indemnified Party with a sufficient number of copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning of
the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged untrue statement of a material fact or any
omission or alleged omission to state therein a material fact required to be
stated in the registration statement or prospectus or any amendment thereof or
supplement thereto or necessary to make the statements therein not misleading,
but only to the extent that such untrue or alleged untrue statement or omission
or alleged omission is contained in or omitted from information so furnished in
writing to AmPaM by such Stockholder expressly for use in 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.

<PAGE>   66




                  (c) Any person entitled to indemnification hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i) each
participating Stockholder shall execute and deliver to AmPaM a written power of
attorney instrument that (A) appoints an officer of AmPaM as such Stockholder's
attorney-in-fact for purposes of executing and delivering an underwriting
agreement among AmPaM, the underwriters named therein and such Stockholder
specifying the terms and conditions applicable to the sale of AmPaM Stock of
such Stockholder in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering in which
one or more stockholders of the issuer are participants, including a provision
that authorizes the attorney-in-fact appointed by such Stockholder to execute
and deliver such an underwriting agreement in the event that the net price per
share to be received by such Stockholder from the sale of the shares of AmPaM
Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters specifically for inclusion in any such registration statement and
(B) such Stockholder shall not be obligated to enter into such an underwriting
agreement in the event that the net price per share to be received by such
Stockholder from the sale of shares of AmPaM Stock to be sold in such offering
is less than the floor price specified in the power of attorney instrument
executed and delivered to AmPaM pursuant to clause (i) above.

<PAGE>   67


         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares of
AmPaM Stock under this Agreement may be assigned to a transferee or assignee of
any Stockholder to the extent that such transferee or assignee is a member of
the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

                  (i) make and keep public information regarding AmPaM available
         as those terms are understood and defined in Rule 144 under the 1933
         Act beginning 90 days following the effective date of a registration
         statement relating to an IPO;

                  (ii) file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 AmPaM, 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.

         17.7 CONVERTED SHARES OF AMPAM SERIES A PREFERRED STOCK. The provisions
of this Section 17 shall apply to any and all shares of AmPaM Stock issued in
connection with the conversion of AmPaM Series A Preferred Stock into AmPaM
Stock.

18.      REDEMPTION OF AMPAM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal payments,
if any, made with respect to AmPaM Notes held by such Stockholder) equal to or
exceeding 50% of the Aggregate Consideration on or prior to the third
anniversary of the Closing Date, such Stockholder shall have the right (the "Put
Right"), but not the obligation, commencing on the third anniversary of the
Closing Date to require AmPaM to purchase a number of shares of AmPaM Stock then
owned by such Stockholder, subject to the limitations set


                                       59

<PAGE>   68


forth in Section 18.2 below. The purchase price for such redemption shall be
$13.00 per share, such price to be subject to appropriate adjustment to reflect
any reclassification, stock dividend, subdivision, split-up or combination of
shares of AmPaM Stock after the date hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified, AmPaM
shall be obligated to purchase from each eligible Stockholder no less than 10%
of the AmPaM Stock held by such Stockholder annually; provided, however, that
the Stockholders shall not be entitled to exercise their Put Rights if and to
the extent the Company has not achieved the Target Net Income (as defined in
Annex I hereto) for the year preceding the year in which a Stockholder seeks to
exercise his Put Right. The redemptions will be funded by internal cash flows or
alternative financing arrangements but AmPaM's obligation to make any redemption
pursuant to this Section 18 will be subject to the covenants and restrictions
contained in AmPaM's then existing private or public debt or equity instruments.

         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right by
giving written notice (the "Put Notice") to AmPaM within thirty (30) days of the
third anniversary of the execution hereof. If any Stockholder does not provide
AmPaM with a Put Notice within such thirty-day period, the Put Right applicable
to such Stockholder shall expire. The date for closing the sale of any shares of
AmPaM Stock pursuant to a proper exercise of a Put Right shall in no event be
earlier than 90 days after the date AmPaM receives the Put Notice. Any such
closing shall be at such time of day and place as shall be mutually agreed
between such holder and AmPaM. At such closing AmPaM shall make payment for the
AmPaM Stock to be repurchased by wire transfer of immediately available funds to
a bank account designated by such Stockholder for such purpose and such
Stockholder shall deliver to AmPaM certificates, duly endorsed for transfer,
representing the shares of AmPaM Stock to be purchased and sold pursuant to the
exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger or
consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any, which are then held by persons other than the holders of AmPaM Common Stock
as of the Closing


                                       60

<PAGE>   69


Date constitute 50% or more of AmPaM Common Stock outstanding as of the date of
the consummation of such transaction.

19.      GENERAL

         19.1 COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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
AmPaM on and after the Closing 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 Closing Date.

         19.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law and except as

benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

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

the Company and AmPaM 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 by
a written instrument executed by the Stockholders, the Company and AmPaM, 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.

         19.4 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. A telecopied
facsimile of an executed counterpart of this Agreement shall be sufficient to
evidence the binding agreement of each party to the terms hereof. However, each
party agrees to return to the other parties an original, duly executed
counterpart of this Agreement promptly after delivery of a telecopied facsimile
thereof.

         19.5 BROKERS AND AGENT. Except as disclosed on Schedule 18.5, each
party hereto 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.

         19.8 GOVERNING LAW. This Agreement shall be construed in accordance
with the laws of the State of Texas, excluding any conflicts of law, rule or
principle that might refer same to the laws of another jurisdiction.

         19.9 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations,

herein, no delay of or omission in the exercise of any right, power or remedy
accruing to any party as a result of any breach or default by any other party
under this Agreement shall impair any such right, power or remedy, nor shall it
be construed as a waiver of or acquiescence in any such breach or default, or of
any similar breach or default occurring later; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
occurring before or after that waiver.

         19.11 TIME. Time is of the essence with respect to this Agreement.

         19.12 REFORMATION AND SEVERABILITY. In case any provision of this
Agreement shall be invalid, illegal or unenforceable, it shall, to the extent
possible, be modified in such manner as to be valid, legal and enforceable but
so as to most nearly retain the intent of the parties, and if such modification
is not possible, such provision shall be severed from this Agreement, and in
either case the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby. No provision of this Agreement shall be interpreted or construed
against any party solely because that party or its legal representative drafted
such provision.

         19.13 REMEDIES CUMULATIVE. No right, remedy or election given by any
term of this Agreement shall be deemed exclusive but each shall be cumulative
with all other rights, remedies and elections available at law or in equity.

and the observance of any term of this Agreement may be waived only with the
written consent of AmPaM, the Company and Stockholders who would receive a
majority of the Aggregate Consideration specified in Section I of Annex I to
this Agreement if the transactions contemplated hereby were consummated. Any
amendment or waiver effected in accordance with this Section 19.15 shall be
binding upon each of the parties hereto, any other person receiving AmPaM Stock
or AmPaM Series A Preferred Stock in connection with the purchase and sale of
the Company Stock and each


                                       64

<PAGE>   73


future holder of such AmPaM Stock or AmPaM Series A Preferred Stock. Any consent
of the Stockholders who would receive a majority of the Aggregate Consideration
pursuant to Section I of Annex I of this Agreement if the transactions
contemplated hereby were consummated shall be deemed to be the consent of the
Stockholders for purposes of provisions of this Agreement as to which a consent
of the Stockholders may be requested or required.

         19.16 MEDIATION AND ARBITRATION. If a dispute arises out of or relates
to this Agreement, or the breach thereof, and if said dispute cannot be settled
through direct discussions, the parties agree to first endeavor to settle the
dispute in an amicable manner by mediation administered by the American
Arbitration Association under its then prevailing Commercial Mediation Rules,
before resorting to arbitration. Thereafter, any unresolved controversy or claim
arising out of or relating to this Agreement, or the breach thereof, shall be
settled by arbitration administered by the American Arbitration Association in
accordance with its then prevailing Commercial Arbitration Rules. The
enforcement, interpretation and procedural and substantive effect of the
obligation to arbitrate created by this Section 19.16 shall be governed by the
Federal Arbitration Act as amended from time to time, 9 U.S.C. Sections 1 et
seq. The parties hereby disclaim any intention to have the substantive or
procedural law of any state or other jurisdiction, other than the law of the
United States as embodied in the Federal Arbitration Act, applied to such
obligation. Any such mediation or arbitration proceeding will be conducted in
Houston, Texas.

         5.19 EMPLOYEE PLANS. The Company has delivered to AmPaM accurate
schedule (Schedule 5.19(a)) showing all employee benefit plans of the Company,
including all employment agreements and other agreements or arrangements
containing "golden parachute" or other similar provisions, and deferred
compensation agreements, together with true, complete and correct copies of such
plans, agreements and any trusts related thereto, and classifications of
employees covered thereby as of the Balance Sheet Date and as of the date of
this Agreement. Except for the employee benefit plans, if any, described on
Schedule 5.19(a), the Company does not sponsor, maintain or contribute to any
plan program, fund or arrangement that constitutes an "employee pension benefit
plan", and neither the Company nor any Subsidiary has any obligation to

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" shall have the same meaning as is given that
term in Section 3(2) of ERISA. The Company has not sponsored, maintained or
contributed to any employee pension benefit plan other than the plans set forth
on Schedule 5.19(a), and, except as described on Schedule 5.19(b), 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
conditions or employment of any of the Company's employees.

         Except as set forth on Schedule 5.19(c), the Company is not now, or
will not as a result of its past activities become, liable to the Pension
Benefit Guaranty Corporation 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(a) and the
administration thereof are in compliance in all material respects 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 as of the Balance
Sheet Date with respect to any plan listed on Schedule 5.19(a) have either been
fulfilled in their entirety or are fully reflected on the balance sheet of the
Company as of the Balance Sheet Date.

         5.20 COMPLIANCE WITH ERISA. All plans listed on Schedule 5.19(a) that
are intended to qualify under Section 401 (a) of the Code (the "Qualified
Plans") are, and have been so qualified and have been determined by the Internal
Revenue Service to be so qualified, and copies of such determination letters are
attached to Schedule 5.19(a). 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) since January 1, 1992 have been
timely filed or distributed, and copies thereof have been made available to
AmPaM. No such plan listed on Schedule 5.19(a) 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 on Schedule 5.19(a) 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 Pension Benefit Guaranty Corporation. The Company further represents that
except as set forth on Schedule 5.20 hereto:

                  (i) there have been no terminations, partial terminations or
         discontinuations of contributions to any Qualified Plan intended to
         qualify under Section 401(a) of the Code without notice to and approval
         by the Internal Revenue Service;

         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(a);

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

                  (v) no circumstances exist pursuant to which the Company could
         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.

notice of any claim, action, suit or proceeding, whether pending or threatened,
has been received by the Company, and to the knowledge of the Company there is
no valid basis for any such claim, action, suit or proceeding that could
reasonably be expected to have a Material Adverse Effect on the Company.

and other Tax Returns or extension requests for all fiscal periods ended on or
before the Balance Sheet Date; and except as set forth on Schedule 5.22(a),
there are no examinations in progress or claims pending against the Company for

have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods indicated (except as noted thereon), and the balance

are reasonable, and such pro forma adjustments have been properly applied to the
historical financial amounts in the compilation of the pro forma financial
statements. Based on the representations in Section 5.9 of this Agreement and in

Agreement and the Other Agreements and except for fees incurred in connection
with the transactions contemplated hereby and thereby.

         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, 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 reasonably
satisfactory to the Indemnified Party, 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 or a conflict of
interest is reasonably likely to arise that prevents counsel for the
Indemnifying Party from representing such 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


                                       42
<PAGE>   51




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, 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. 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 pay the Indemnified Party for the settlement amount 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.
With respect to any account, note or other receivable as to which the
Stockholders have paid in full any indemnification obligation pursuant to this
Section 11 as a result of a breach of the representation and warranty made
pursuant to Section 5.11 or as to which a claim in respect thereof has been
asserted pursuant to this Section 11 that has been applied against the
Indemnification Threshold with respect to the Stockholders as a result of a
breach of the representation and warranty made pursuant to Section 5.11, AmPaM
shall cause the Company to assign such account, note or other receivable to the
Stockholders. 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. 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 to this Agreement with respect to any
provision of this Agreement, provided that, nothing herein shall be construed to
limit the right of a party, in a proper case, to seek injunctive relief for a
breach of this Agreement. AmPaM hereby waives, to the fullest extent permitted
under applicable law, any and all other rights, claims and causes of action,
known or unknown, it or any indemnified person may have against the Company or
any Stockholder relating to this Agreement or the transactions pursuant to this
Agreement arising under or based upon any Federal, state, local or foreign
statute, law, rule, regulation or otherwise. 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


                                       43
<PAGE>   52




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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2 (calculated as provided in this Section 11.5) plus (iii) the
principal amount of the AmPaM Notes delivered to the Stockholders pursuant to
Section 1.2, or (b) $50,000 (the "Indemnification Threshold"). Stockholders
shall not assert any claim for indemnification hereunder against AmPaM until
such time as, and solely to the extent that, the aggregate of all claims which
Stockholders may have against AmPaM shall exceed $50,000; provided, however,
that this sentence shall not be applicable with respect of any failure by AmPaM
to (i) deliver the consideration specified in Annex I hereto on the Closing Date
upon the satisfaction, or waiver by AmPaM, of all conditions to the occurrence
of the Closing Date specified in Section 9 or (ii) comply with its obligations
pursuant to Section 10.1. After the $50,000 threshold for AmPaM (subject to the
proviso in the preceding sentence) or the Indemnification Threshold for a
Stockholder has been met, all claims must be made in $10,000 increments, which
claims may be cumulated in order to meet such $10,000 thresholds. For purposes
of this paragraph, the AmPaM Stock delivered to the Stockholders shall be valued
at $13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is directly
or indirectly related to a breach by such person of any representation,
warranty, covenant or other agreement set forth in this Agreement. No claim for
indemnification against the Stockholders shall limit, diminish or change any
obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at $13.00
per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of AmPaM
Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration paid to such Stockholder by AmPaM to such Stockholder pursuant to
Annex I. For the purpose of crediting Stockholders for payments made to AmPaM by
means of delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued at
$13.00 per share.


                                       44
<PAGE>   53




         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary of
AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM shall use commercially reasonable
efforts to pursue any available insurance coverage or other rights of indemnity
or reimbursement from third parties with respect to any such loss, liability or
expense.

12.      TERMINATION OF AGREEMENT

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

                  (i) by mutual consent of AmPaM and the Stockholders;

                  (ii) by the Stockholders, if the transactions contemplated by
         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by the Company
         or the Stockholders prior to or on the Closing Date;

                  (iii) by AmPaM, if the transactions contemplated by this
         Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by AmPaM prior
         to or on the Closing Date;

                  (iv) by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein
         relating to AmPaM, and the curing of such default shall not have been
         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v) by AmPaM, if a material breach or default shall be made by
         the Company or the Stockholders in the observance or in the due and
         timely performance of any of the covenants or agreements contained
         herein relating to the Company or the Stockholders, and the curing of
         such default shall not have been made (or in the reasonable judgment of
         AmPaM cannot be made) on or before the Closing Date;

                  (vi) by the Stockholders, if the conditions set forth in
         Section 8 hereof have not been satisfied or waived as of the Closing
         Date; or



                                       45
<PAGE>   54




                  (vii) by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2 PROCEDURE AND EFFECT OF TERMINATION. A determination to terminate
this Agreement by AmPaM pursuant to Section 12.1 shall be valid and effective
only if a written notice of termination, accompanied by a certified copy of
resolutions of the board of directors of AmPaM that evidence the authorization
of the officer of AmPaM to deliver a written notice of termination of this
Agreement pursuant to Section 12.1, is given to the Stockholders in the manner
specified for notices in this Agreement. A determination to terminate this
Agreement by the Stockholders pursuant to Section 12.1 shall be valid and
effective only if a written notice of termination, signed by Stockholders who
would be entitled to receive a majority of the shares of AmPaM Stock specified
in Section I of Annex I to this Agreement if the transactions contemplated
hereby were consummated, is given to AmPaM in the manner specified for notices
in this Agreement. Upon the giving of notice of termination of this Agreement
pursuant to Section 12.1 as specified in the preceding sentence, this Agreement
shall terminate, and the transactions contemplated hereby shall be abandoned,
without further action by any of the parties hereto. Immediately upon any such
termination, AmPaM shall deliver written notice of such termination to the Other
Founding Companies. If this Agreement is terminated as provided in this Section
12, no party hereto shall have any liability or further obligation hereunder to
any other party, except as provided in Section 14 and Section 18.6, provided,
that, 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 that occurred prior to such termination.

13.      NONCOMPETITION

         13.1 PROHIBITED ACTIVITIES. The Stockholders will not, without the
prior written consent of AmPaM, for a period of two (2) years following the
Closing 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) 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, whether paid or unpaid, in any plumbing, piping,
         mechanical, heating, ventilation or air conditioning contracting,
         installation or services business or operation, whether for
         residential, commercial, industrial or governmental customers, or any
         ancillary contracting, installation or services business directly
         related thereto (such business and operations referred to herein as the
         "Plumbing and Mechanical Business"), within 100 miles of where the
         Company or any of its subsidiaries conducted business within two (2)
         years prior to the Closing Date (the "Territory");



                                       46
<PAGE>   55




                  (ii) call upon any person who is, at the Closing Date, within
         the Territory, an employee of AmPaM or any subsidiary thereof for the
         purpose or with the intent of enticing such employee away from or out
         of the employ of AmPaM or any subsidiary thereof;

                  (iii) call upon any person or entity which is, at the Closing
         Date, or which has been within three (3) years prior to the Closing
         Date, a customer of AmPaM or any subsidiary thereof, of the Company or
         of any of the Other Founding Companies for the purpose of soliciting
         customers, orders or contracts for any Plumbing and Mechanical Business
         in direct competition with AmPaM within the Territory;

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

                  (v) disclose to any person, firm, partnership, corporation or
         business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or any
         of its subsidiaries within the two (2) years prior to the Closing Date
         for any reason or purpose whatsoever except to the extent that the
         Company has in the past disclosed such information to the public for
         valid business reasons; or

                  (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

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



                                       47
<PAGE>   56




         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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by AmPaM of such
covenants. It is specifically agreed that the period of two (2) 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
found to be in violation of any provision of this Section 13 as determined by
any of (i) a written agreement to such effect executed and delivered by AmPaM
and such Stockholder, (ii) a determination by an arbitration panel pursuant to
an arbitration conducted pursuant to Section 18.16 hereof or (iii) a
non-appealable judgment of a court of competent jurisdiction. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto. The covenants contained in Section 13
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
the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and pricing and cost
policies that are valuable, special and unique assets of the Company's, the
Other Founding Companies' and/or AmPaM'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 AmPaM, (b) following the
Closing, such information may be disclosed by the Stockholders as is required in
the course of performing their duties for AmPaM or the Company and (c) to its
counsel and other advisers, provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 14.1; provided, however
that (i) the foregoing


                                       48
<PAGE>   57




disclosure prohibition shall not apply in the event that (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 AmPaM and provide AmPaM 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, AmPaM 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
AmPaM 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 AMPAM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies that
are valuable, special and unique assets of the Company's business. AmPaM agrees
that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes known
to the public generally through no fault of AmPaM, (B) 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 (B), AmPaM
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 (C) 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 AmPaM of
the provisions of this Section 14.2, the Company and the Stockholders shall be
entitled to an injunction restraining AmPaM 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.
In the event the transactions contemplated by this Agreement are not consummated
for any reason, AmPaM shall nevertheless remain subject to this Section 14.2,
except that it shall not be permitted to make any disclosures otherwise than
pursuant to clause (A), (B) or (C) above.



                                       49
<PAGE>   58




         14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

         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 Closing Date.

         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AMPAM STOCK AND AMPAM NOTES. For
a period of two years from the Closing Date or, in the event that the Company
completes an IPO, for a period through the second anniversary of the date of the
closing of such IPO (the "Restricted Period"), no Stockholder shall (i) sell,
assign, exchange, transfer, pledge, or otherwise dispose of any shares of AmPaM
Stock or AmPaM Notes received by the Stockholders pursuant to this Agreement or
any securities convertible into, exchangeable or exercisable for any shares of
AmPaM Stock or AmPaM Notes received by such Stockholder pursuant to this
Agreement, (ii) grant any option to purchase, or otherwise enter into any
contract to sell, assign, transfer, pledge or otherwise dispose of, any shares
of AmPaM Stock or AmPaM Notes received by such Stockholder pursuant to this
Agreement, or (iii) enter into any swap or any other agreement or any
transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of the AmPaM Stock or AmPaM Notes, whether any
such swap or transaction is to be settled by delivery of shares of AmPaM Stock
or AmPaM Notes or other securities, by the delivery or payment of cash or
otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A) as
otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock, pursuant
to Section 17 hereof, (C) for transfers to (I) immediate family members of such
Stockholder who agree with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1, (II) trusts, limited partnerships or other estate
planning entities for the benefit of such Stockholder or family members of such
Stockholder which have agreed with AmPaM in writing, through action taken by the
trustees, partners or other persons having authority to bind the trust, limited
partnership or other estate planning entity, to be bound by the restrictions set
forth in this Section 15.1, (III) any charitable organization that qualifies for
receipt of charitable contributions under Section 170(c) of the Code which
agrees with AmPaM in writing to be bound by the restrictions set forth in this
Section 15.1, (D) for transfers of AmPaM Stock or AmPaM Notes to AmPaM pursuant
to Section 11.5(d), (E) for transfers to another Stockholder, to another person
or entity who receives shares of AmPaM Stock or AmPaM Notes or AmPaM Series A
Preferred Stock pursuant to the Other Agreements or to Sterling City Capital LLC
or any of its Affiliates provided that (1) such transaction is exempt from the
registration requirements of the 1933 Act as evidenced by the delivery to AmPaM
of an opinion of counsel in form and substance reasonably satisfactory to AmPaM
and


                                       50
<PAGE>   59




(2) any such transferee agrees in writing to be bound by the restrictions set
forth in this Section 15.1, (F) transfers of shares of AmPaM Notes, shares of
AmPaM Stock, or grants of options to purchase shares of AmPaM Stock, by such
Stockholder to employees of the Company of up to an aggregate of 15% of the
shares of AmPaM Stock received by such Stockholder pursuant to this Agreement
provided that (1) any such transaction is exempt from the registration
requirements of the 1933 Act as evidenced by the delivery to AmPaM of an opinion
of counsel in form and substance reasonably satisfactory to AmPaM and (2) any
such employee agrees with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1 or (G) the sale by such Stockholder in an IPO of
shares of AmPaM Stock representing not more than 10% of the Aggregate
Consideration in cash; provided, however, that in no circumstance will a
Stockholder be entitled to sell shares of AmPaM Stock in an IPO to the extent
that the sale of such shares by such Stockholder would result in such
Stockholder receiving in excess of 45% of the Aggregate Consideration in cash;
and, provided further, if AmPaM 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 Section 17.1 that the number of
shares to be sold by persons other than AmPaM is greater than the number of such
shares which can be offered without adversely affecting the success of the
offering, AmPaM may reduce pro rata (among the Stockholders and all other
selling security holders in the offering) 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. During the
Restricted Period, the certificates evidencing the AmPaM Stock or AmPaM Notes
delivered to the Stockholders pursuant to Section 3 of this Agreement will bear
a legend substantially in the form set forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION
OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly


                                       51
<PAGE>   60




or indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the shares
of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to be
delivered to such 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 sold, assigned, exchanged, transferred, pledged or
otherwise disposed of without compliance with the 1933 Act which, among other
matters, would require registration under the 1933 Act unless exemption from the
registration requirements is available for such transaction. The AmPaM Stock,
the Additional Consideration Right and any AmPaM Notes to be acquired by each
Stockholder pursuant to this Agreement is being acquired solely for such
Stockholder's own account, for investment purposes only, and with no present
intention of selling, assigning, exchanging, transferring, pledging, or
otherwise disposing of it. Each Stockholder covenants, warrants and represents
that neither the shares of AmPaM Stock, the Additional Consideration Right nor
any AmPaM Notes issued to such Stockholder will be offered, sold, assigned,
exchanged, pledged, 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 certificates representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision), and
is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of the
nature described in the preceding sentence and all questions have been answered
to such Stockholder's satisfaction. Except as set forth on Schedule 16.2, each
Stockholder is an "accredited investor" as defined in Rule 501(a) of the 1933
Act. Neither the foregoing nor any investigation made by the Stockholders
referred to above shall in any way affect the representations, warranties,


                                       52
<PAGE>   61




covenants and agreements of AmPaM made herein except to the extent that AmPaM is
relying upon the representations of the Stockholders in Section 16.1 and in this
Section 16.2 for purposes of AmPaM's representations and warranties in Sections
6.9, 6.11, 6.15 and 6.17 hereof as specified therein.

         16.3 RELIANCE BY AMPAM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to register
any AmPaM Stock for its own or other's 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 AmPaM and (ii)
registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other distribution with respect
to, or in exchange for, or in replacement of such AmPaM Stock) which any such
Stockholder requests, other than shares of AmPaM Stock which may then be
immediately sold under Rule 144(k) (or any similar or successor provision)
promulgated under the 1933 Act, and other than shares of AmPaM Stock that have
been theretofore sold by the Stockholder in accordance with the 1933 Act,
provided that AmPaM shall have the right to reduce pro rata the number of shares
of each selling Stockholder included in such registration to the extent that
inclusion of such shares would, in the written opinion of tax counsel to AmPaM
or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Private Placement Memorandum as a tax-free
organization under Section 351 of the Code; provided, however, that with respect
to a proposal by AmPaM to register AmPaM Stock under the 1933 Act in connection
with an IPO, no Stockholder shall be permitted pursuant to this Section 17.1 to
have included in such registration more shares of AmPaM Stock than permitted to
be sold by such Stockholder pursuant to Section 15.1. In addition, if AmPaM 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 AmPaM is greater than the number of such shares which can be offered
without adversely affecting the success of the offering, AmPaM may reduce pro
rata (among the Stockholders and all other selling security holders in the
offering) 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. If any Stockholder disapproves of the terms of the
underwriting, that Stockholder may elect to withdraw therefrom by written notice
to AmPaM and the managing underwriter. That


                                       53
<PAGE>   62



Stockholder's shares of AmPaM Stock so withdrawn shall also be withdrawn from
registration; provided, however, that, if by the withdrawal of such shares a
greater number of shares of AmPaM Stock held by other Stockholders may be
included in such registration, then AmPaM shall offer to all other Stockholders
of AmPaM the right to include additional shares in the same proportion used in
effecting the above limitations. AmPaM shall not, for a period of two years
following the Closing Date, grant to any other person any rights to cause AmPaM
to register any securities in priority over, or in precedent to, the rights
granted to the Stockholders hereunder and to the stockholders of the Other
Founding Companies pursuant to Section 17 of the Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a representative of the
         Stockholders with copies of all such documents proposed to be filed) as
         promptly as practical;

                  (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such registration statement or supplement to the prospectus;

                  (iv) 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;

                  (v) Make "generally available to its security holders" (within
         the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;


                                       54
<PAGE>   63




                  (vi) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of the registration statement at
         the earliest possible moment;

                  (vii) If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment such
         information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM Stock being sold by
         participating Stockholders to any underwriter or underwriters, the
         purchase price being paid therefor by such underwriter or underwriters
         and with respect to any other terms of an underwritten offering of the
         shares of AmPaM Stock to be sold in such offering, and promptly make
         all required filings of such prospectus by supplement or post-effective
         amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition pursuant
         to such registration statement, and the counsel retained by the
         participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or any
         such underwriter (collectively, the "Inspectors"), all financial and
         other records, pertinent corporate documents and properties of AmPaM
         (the "Records"), as shall be reasonably necessary to enable them to
         exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x) 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 required to
         be kept effective, provided that AmPaM shall not be required to become
         subject to taxation, to qualify generally to do business or to file a
         general consent to service of process in any such states or
         jurisdictions;

                  (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any


                                       55
<PAGE>   64




         securities exchanges or trading systems on which similar securities
         issued by AmPaM are then listed or included; and

                  (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in effect),
         together with any associated term sheet, contains an untrue statement
         of a material fact or omits to state any fact required to be stated
         therein or necessary to make the statements therein (in the case of the
         prospectus or any preliminary prospectus, in light of the circumstances
         under which they were made) not misleading, and, at the request of such
         Stockholder, AmPaM promptly 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 required to be
         stated therein or necessary to make the statements therein (in the case
         of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall be
borne by AmPaM.

         17.3 INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue statement
of material fact contained or incorporated by reference in any registration
statement, prospectus or preliminary prospectus or associated term sheet or any
omission or alleged omission to state or incorporated by reference therein a
material fact required to be stated or incorporated by reference 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 AmPaM 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 AmPaM has furnished
such Indemnified Party with a sufficient number of copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning of
the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged


                                       56
<PAGE>   65




untrue statement of a material fact or any omission or alleged omission to state
therein a material fact required to be stated in the registration statement or
prospectus or any amendment thereof or supplement thereto or necessary to make
the statements therein not misleading, but only to the extent that such untrue
or alleged untrue statement or omission or alleged omission is contained in or
omitted from information so furnished in writing to AmPaM by such Stockholder
expressly for use in 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 hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i) each
participating Stockholder shall execute and deliver to AmPaM a written power of
attorney instrument that (A) appoints an officer of AmPaM as such Stockholder's
attorney-in-fact for purposes of executing and delivering an underwriting
agreement among AmPaM, the underwriters named therein and such Stockholder
specifying the terms and conditions applicable to the sale of AmPaM Stock of
such Stockholder in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering in which
one or more stockholders of the issuer are participants, including a provision
that authorizes the attorney-in-fact appointed by such Stockholder to execute
and deliver such an underwriting agreement in the event that the net price per
share to be received by such Stockholder from the sale of the shares of AmPaM
Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters


                                       57
<PAGE>   66




specifically for inclusion in any such registration statement and (B) such
Stockholder shall not be obligated to enter into such an underwriting agreement
in the event that the net price per share to be received by such Stockholder
from the sale of shares of AmPaM Stock to be sold in such offering is less than
the floor price specified in the power of attorney instrument executed and
delivered to AmPaM pursuant to clause (i) above.

         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares of
AmPaM Stock under this Agreement may be assigned to a transferee or assignee of
any Stockholder to the extent that such transferee or assignee is a member of
the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

                  (i) make and keep public information regarding AmPaM available
         as those terms are understood and defined in Rule 144 under the 1933
         Act beginning 90 days following the effective date of a registration
         statement relating to an IPO;

                  (ii) file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 AmPaM, 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.      REDEMPTION OF AMPAM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal payments,
if any, made with respect to AmPaM Notes held by such Stockholder) equal to or
exceeding 50% of the Aggregate Consideration on or prior to the third
anniversary of the Closing Date, such Stockholder shall have the right (the "Put
Right"), but not the


                                       58
<PAGE>   67




obligation, commencing on the third anniversary of the Closing Date to require
AmPaM to purchase a number of shares of AmPaM Stock then owned by such
Stockholder, subject to the limitations set forth in Section 18.2 below. The
purchase price for such redemption shall be $13.00 per share, such price to be
subject to appropriate adjustment to reflect any reclassification, stock
dividend, subdivision, split-up or combination of shares of AmPaM Stock after
the date hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified, AmPaM
shall be obligated to purchase from each eligible Stockholder no less than 10%
of the AmPaM Stock held by such Stockholder annually; provided, however, that
the Stockholders shall not be entitled to exercise their Put Rights if and to
the extent the Company has not achieved the Target Net Income (as defined in
Annex I hereto) for the year preceding the year in which a Stockholder seeks to
exercise his Put Right. The redemptions will be funded by internal cash flows or
alternative financing arrangements but AmPaM's obligation to make any redemption
pursuant to this Section 18 will be subject to the covenants and restrictions
contained in AmPaM's then existing private or public debt or equity instruments.

         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right by
giving written notice (the "Put Notice") to AmPaM within thirty (30) days of the
third anniversary of the execution hereof. If any Stockholder does not provide
AmPaM with a Put Notice within such thirty-day period, the Put Right applicable
to such Stockholder shall expire. The date for closing the sale of any shares of
AmPaM Stock pursuant to a proper exercise of a Put Right shall in no event be
earlier than 90 days after the date AmPaM receives the Put Notice. Any such
closing shall be at such time of day and place as shall be mutually agreed
between such holder and AmPaM. At such closing AmPaM shall make payment for the
AmPaM Stock to be repurchased by wire transfer of immediately available funds to
a bank account designated by such Stockholder for such purpose and such
Stockholder shall deliver to AmPaM certificates, duly endorsed for transfer,
representing the shares of AmPaM Stock to be purchased and sold pursuant to the
exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger or
consolidation which involves AmPaM and in which AmPaM is not the surviving

to this Agreement, or the breach thereof, and if said dispute cannot be settled
through direct discussions, the parties agree to first endeavor to settle the
dispute in an amicable manner by mediation administered by the American

arising out of or relating to this Agreement, or the breach thereof, shall be
settled by arbitration administered by the American Arbitration Association in

seq. The parties hereby disclaim any intention to have the substantive or
procedural law of any state or other jurisdiction, other than the law of the

         6.1 DUE ORGANIZATION. AmPaM is a corporation duly incorporated and
organized, validly existing and in good standing under the laws of the State of
Delaware, and has the requisite power and authority to carry on its business as
it is now being conducted and as contemplated by the Private Placement
Memorandum. AmPaM is duly qualified or authorized to do business and is in good
standing in each jurisdiction in which the nature of its business or the
ownership or leasing of its properties makes such qualification or authorization
necessary, except where the failure to be so qualified or authorized to do
business would not have a Material Adverse Effect. True, complete and correct
copies of the Certificate of Incorporation and By-laws, each as proposed to be
amended and as such documents shall be in effect as of the Closing Date, of
AmPaM (the "AmPaM Charter Documents") are attached hereto as Annex II.

         6.2 AUTHORIZATION. (i) The officers of AmPaM executing this Agreement
have the authority to enter into and bind AmPaM to the terms of this Agreement
and (ii) AmPaM has the full legal right, power and authority to enter into this
Agreement and consummate the transactions contemplated hereby. All corporate
acts and other proceedings required to have been taken by AmPaM to authorize the
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby have been duly and properly taken.

         6.3 CAPITAL STOCK OF AMPAM. The authorized capital stock of AmPaM is as
set forth in Section 1.3(ii). Immediately prior to the Closing Date, all of the
issued and outstanding shares of the capital stock of AmPaM will be as set forth
in the Private Placement Memorandum, free and clear of all liens, security
interests, pledges, charges, voting trusts, restrictions, encumbrances and
claims of every kind other than any restrictions described in the Private
Placement Memorandum. All of the issued and outstanding shares of the capital
stock of AmPaM have been duly authorized and validly issued, are fully paid and
nonassessable and such shares were offered, issued, sold and delivered by AmPaM
in compliance with all applicable state and Federal laws concerning the issuance
of securities. Further, none of such shares were issued in violation of the
preemptive rights of any past or present stockholder of AmPaM. Upon the Closing
Date, the authorized, issued and outstanding shares of capital stock of AmPaM
will be as set forth in the Private Placement Memorandum under the caption
"Capitalization." Upon the Closing Date, the aggregate number of shares of AmPaM
Stock issued and outstanding on the Closing Date that are owned by Sterling City
Capital, LLC, any Affiliates of Sterling City Capital, LLC and the officers and
directors of AmPaM will not be greater than the number of shares of AmPaM Stock
reflected in the Private Placement Memorandum as the aggregate number of shares
of AmPaM Stock to be issued and outstanding and owned by Sterling City Capital,
LLC, any Affiliates of Sterling City Capital, LLC and the officers and directors
of AmPaM.

         6.4 TRANSACTIONS IN CAPITAL STOCK. Except for the Other Agreements and
except as set forth in the Private Placement Memorandum, (i) no option, warrant,
call, conversion right or commitment of any kind exists as of the date of this
Agreement which obligates AmPaM to issue any of its authorized but unissued
capital stock; and (ii) AmPaM has no obligation (contingent or otherwise) to
purchase, redeem or otherwise acquire any of its equity securities or any
interests therein or to pay any dividend or make any distribution in respect
thereof. The material terms of any


                                       24

<PAGE>   33



options, warrants or other rights to acquire shares of the stock of AmPaM
referred to in the preceding sentence will be as described in the Private
Placement Memorandum.

         6.5 SUBSIDIARIES. As of the date of this Agreement, AmPaM has no
subsidiaries. As of the date of this Agreement, AmPaM does not own, of record or
beneficially, or control, directly or indirectly, any capital stock, securities
convertible into capital stock or any other equity interest in any corporation,
association or business entity, and AmPaM is not, directly or indirectly, a
participant in any joint venture, partnership or other non-corporate entity.

         6.6 FINANCIAL STATEMENTS. The historical financial statements of AmPaM
included in the Private Placement Memorandum (the "AmPaM Financial Statements")
have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods indicated (except as noted thereon), and the balance
sheet included therein presents fairly the financial position of AmPaM as of its
date. Management of AmPaM believes that the assumptions underlying the pro forma
adjustments utilized in the preparation of such pro forma financial statements
are reasonable, and such pro forma adjustments have been properly applied to the
historical financial amounts in the compilation of the pro forma financial
statements. Based on the representations in Section 5.9 of this Agreement and in
Section 5.9 of each of the Other Agreements, the pro forma financial information
of AmPaM fairly presents the pro forma financial position, results of operations
and other information purported to be shown therein at the respective dates and
for the respective periods specified.

         6.7 LIABILITIES AND OBLIGATIONS. Except as set forth in the Private
Placement Memorandum, as of the date of this Agreement, AmPaM has no material
liabilities or obligations of any kind, character or description, whether
accrued, absolute, secured or unsecured, contingent or otherwise, other than
liabilities incurred in the ordinary course of business and consistent with past
practices, liabilities or obligations set forth in or contemplated by this
Agreement and the Other Agreements and except for fees incurred in connection
with the transactions contemplated hereby and thereby.

         6.8 CONFORMITY WITH LAW; LITIGATION. Except to the extent set forth in
the Private Placement Memorandum, AmPaM is not in violation of any law or
regulation or any order of any court or Federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality
having jurisdiction over it and its stockholders and, there are no claims,
actions, suits or proceedings, pending or, to the knowledge of AmPaM, threatened
against or affecting, AmPaM, at law or in equity, or before or by any Federal,
state, municipal or other governmental department, commission, board, bureau,
agency or instrumentality having jurisdiction over it and no notice of any
claim, action, suit or proceeding, whether pending or threatened, has been
received. AmPaM has conducted and is conducting its businesses in compliance in
all material respects with the requirements, standards, criteria and conditions
set forth in applicable Federal, state and local statutes, ordinances, permits,
licenses, orders, approvals, variances, rules and regulations and is not in
violation, in any material respect, of any of the foregoing.

         6.11 AmPaM STOCK. At the time of issuance thereof and delivery to the
Stockholders, the AmPaM Stock to be delivered to the Stockholders pursuant to

delivered pursuant to this Agreement, (ii) any breach of any covenant or
agreement on the part of the Company under this Agreement, or (iii) any
liability under the 1933 Act or any Federal or state securities 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 solely to the
Company which was based upon information provided to AmPaM or its counsel in
writing by the Company specifically for inclusion in the Private Placement
Memorandum and is contained in the Private Placement Memorandum, 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 required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that no Stockholder shall be liable
for any


                                       40

indemnification obligation pursuant to this Section 11.1 in excess of such
Stockholder's pro rata share thereof determined by reference to the aggregate
value of the Base Cash Amount (as defined in Annex I of this Agreement), the
principal amount of AmPaM Notes and the shares of AmPaM Stock (valued at a price
of $13.00 per share) received by such Stockholder pursuant to Section I.A. of
Annex I hereto (without giving effect to the adjustments provided in Sections
I.B. and I.C. thereof) (giving effect to the value of such AmPaM Stock and
without giving effect to such adjustments, collectively, the "Aggregate
Consideration") such Stockholder would receive pursuant to Section I of Annex I
of this Agreement if the transactions contemplated hereby were consummated in
relation to the total Aggregate Consideration all Stockholders would receive
pursuant to Section I of Annex I of this Agreement if the transactions
contemplated hereby were consummated.

         (b) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement, 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 AmPaM as a result of or arising from (i)
any breach of the representations and warranties of such Stockholder set forth
in Section 5(B) hereof, (ii) any breach of any covenant or agreement on the part
of such Stockholder under this Agreement, or (iii) any liability under the 1933
Act or any Federal or state securities 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 solely to such Stockholder which was based
upon information provided to AmPaM or its counsel in writing by such Stockholder
specifically for inclusion in the Private Placement Memorandum and is contained
in the Private Placement Memorandum, 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 solely to such Stockholder required to be
stated therein or necessary to make the statements therein in light of the
circumstances in which such statements were made not misleading.

         (c) AmPaM acknowledges and agrees that other than the representations
and warranties of the Company or the Stockholders specifically contained in this
Agreement, there are no representations or warranties of the Company or the
Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

         11.2 INDEMNIFICATION BY AMPAM. AmPaM covenants and agrees that it will
indemnify, defend, protect and hold harmless the Company and the Stockholders at
all times from and after the date of this Agreement until the applicable
Expiration Date (as defined in the introductory paragraph of Section 6, provided
that for purposes of clause (iii) below, the applicable 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 the
Company or the Stockholders as a result of or arising from (i) any breach by
AmPaM of its representations and warranties set forth herein or on the schedules
attached


                                       41
<PAGE>   50


hereto or certificates delivered pursuant to this Agreement, (ii) any breach of
any agreement on the part of AmPaM under this Agreement; or (iii) any liability
under the 1933 Act or any Federal or state securities 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 contained in the Private Placement
Memorandum, 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
required to be stated therein or necessary to make the statements therein not
misleading, except to the extent such is based upon an untrue statement or
alleged untrue statement, or omission or alleged omission, made therein in
reliance upon, and in conformity with, the representations and warranties of the
Company or the Stockholders specifically contained in this Agreement or other
information furnished to AmPaM by the Company or the Stockholders in writing
specifically for inclusion therein.

         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, 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 reasonably
satisfactory to the Indemnified Party, 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 or a conflict of
interest is reasonably likely to arise that prevents counsel for the
Indemnifying Party from representing such 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, 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


                                       42
<PAGE>   51


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. 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 pay the Indemnified Party
for the settlement amount 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. With respect to any account, note or other
receivable as to which the Stockholders have paid in full any indemnification
obligation pursuant to this Section 11 as a result of a breach of the
representation and warranty made pursuant to Section 5.11 or as to which a claim
in respect thereof has been asserted pursuant to this Section 11 that has been
applied against the Indemnification Threshold with respect to the Stockholders
as a result of a breach of the representation and warranty made pursuant to
Section 5.11, AmPaM shall cause the Company to assign such account, note or
other receivable to the Stockholders. 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. 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 to this Agreement with respect to any
provision of this Agreement, provided that, nothing herein shall be construed to
limit the right of a party, in a proper case, to seek injunctive relief for a
breach of this Agreement. AmPaM hereby waives, to the fullest extent permitted
under applicable law, any and all other rights, claims and causes of action,
known or unknown, it or any indemnified person may have against the Company or
any Stockholder relating to this Agreement or the transactions pursuant to this
Agreement arising under or based upon any Federal, state, local or foreign
statute, law, rule, regulation or otherwise. 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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2


                                       43
<PAGE>   52


(calculated as provided in this Section 11.5) plus (iii) the principal amount of
the AmPaM Notes delivered to the Stockholders pursuant to Section 1.2, or (b)
$50,000 (the "Indemnification Threshold"). Stockholders shall not assert any
claim for indemnification hereunder against AmPaM until such time as, and solely
to the extent that, the aggregate of all claims which Stockholders may have
against AmPaM shall exceed $50,000; provided, however, that this sentence shall
not be applicable with respect of any failure by AmPaM to (i) deliver the
consideration specified in Annex I hereto on the Closing Date upon the
satisfaction, or waiver by AmPaM, of all conditions to the occurrence of the
Closing Date specified in Section 9 or (ii) comply with its obligations pursuant
to Section 10.1. After the $50,000 threshold for AmPaM (subject to the proviso
in the preceding sentence) or the Indemnification Threshold for a Stockholder
has been met, all claims must be made in $10,000 increments, which claims may be
cumulated in order to meet such $10,000 thresholds. For purposes of this
paragraph, the AmPaM Stock delivered to the Stockholders shall be valued at
$13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is directly
or indirectly related to a breach by such person of any representation,
warranty, covenant or other agreement set forth in this Agreement. No claim for
indemnification against the Stockholders shall limit, diminish or change any
obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at $13.00
per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of AmPaM
Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration paid to such Stockholder by AmPaM to such Stockholder pursuant to
Annex I. For the purpose of crediting Stockholders for payments made to AmPaM by
means of delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued at
$13.00 per share.

         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary of
AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM


                                       44
<PAGE>   53


shall use commercially reasonable efforts to pursue any available insurance
coverage or other rights of indemnity or reimbursement from third parties with
respect to any such loss, liability or expense.

12.      TERMINATION OF AGREEMENT

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

                  (i) by mutual consent of AmPaM and the Stockholders;

                  (ii) by the Stockholders, if the transactions contemplated by
         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by the Company
         or the Stockholders prior to or on the Closing Date;

                  (iii) by AmPaM, if the transactions contemplated by this
         Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by AmPaM prior
         to or on the Closing Date;

                  (iv) by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein
         relating to AmPaM, and the curing of such default shall not have been
         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v) by AmPaM, if a material breach or default shall be made by
         the Company or the Stockholders in the observance or in the due and
         timely performance of any of the covenants or agreements contained
         herein relating to the Company or the Stockholders, and the curing of
         such default shall not have been made (or in the reasonable judgment of
         AmPaM cannot be made) on or before the Closing Date;

                  (vi) by the Stockholders, if the conditions set forth in
         Section 8 hereof have not been satisfied or waived as of the Closing
         Date; or

                  (vii) by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2 PROCEDURE AND EFFECT OF TERMINATION. A determination to terminate
this Agreement by AmPaM pursuant to Section 12.1 shall be valid and effective
only if a written notice of termination, accompanied by a certified copy of
resolutions of the board of directors of AmPaM that evidence the authorization
of the officer of AmPaM to deliver a written notice of termination of this
Agreement pursuant to Section 12.1, is given to the Stockholders in the manner
specified for notices


                                       45
<PAGE>   54


in this Agreement. A determination to terminate this Agreement by the
Stockholders pursuant to Section 12.1 shall be valid and effective only if a
written notice of termination, signed by Stockholders who would be entitled to
receive a majority of the shares of AmPaM Stock specified in Section I of Annex
I to this Agreement if the transactions contemplated hereby were consummated, is
given to AmPaM in the manner specified for notices in this Agreement. Upon the
giving of notice of termination of this Agreement pursuant to Section 12.1 as
specified in the preceding sentence, this Agreement shall terminate, and the
transactions contemplated hereby shall be abandoned, without further action by
any of the parties hereto. Immediately upon any such termination, AmPaM shall
deliver written notice of such termination to the Other Founding Companies. If
this Agreement is terminated as provided in this Section 12, no party hereto
shall have any liability or further obligation hereunder to any other party,
except as provided in Section 14 and Section 18.6, provided, that, 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 that occurred prior to such termination.

13.      NONCOMPETITION

         13.1 PROHIBITED ACTIVITIES. The Stockholders will not, without the
prior written consent of AmPaM, for a period of two (2) years following the
Closing 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) 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, whether paid or unpaid, in any plumbing, piping,
         mechanical, heating, ventilation or air conditioning contracting,
         installation or services business or operation, whether for
         residential, commercial, industrial or governmental customers, or any
         ancillary contracting, installation or services business directly
         related thereto (such business and operations referred to herein as the
         "Plumbing and Mechanical Business"), within 100 miles of where the
         Company or any of its subsidiaries conducted business within two (2)
         years prior to the Closing Date (the "Territory");

                  (ii) call upon any person who is, at the Closing Date, within
         the Territory, an employee of AmPaM or any subsidiary thereof for the
         purpose or with the intent of enticing such employee away from or out
         of the employ of AmPaM or any subsidiary thereof;

                  (iii) call upon any person or entity which is, at the Closing
         Date, or which has been within three (3) years prior to the Closing
         Date, a customer of AmPaM or any subsidiary thereof, of the Company or
         of any of the Other Founding Companies for the purpose of soliciting
         customers, orders or contracts for any Plumbing and Mechanical Business
         in direct competition with AmPaM within the Territory;


                                       46
<PAGE>   55


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

                  (v) disclose to any person, firm, partnership, corporation or
         business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or any
         of its subsidiaries within the two (2) years prior to the Closing Date
         for any reason or purpose whatsoever except to the extent that the
         Company has in the past disclosed such information to the public for
         valid business reasons; or

                  (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

         13.2 DAMAGES. Because of the difficulty of measuring economic losses to
AmPaM as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to AmPaM for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by AmPaM 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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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.


                                       47
<PAGE>   56


         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by AmPaM of such
covenants. It is specifically agreed that the period of two (2) 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
found to be in violation of any provision of this Section 13 as determined by
any of (i) a written agreement to such effect executed and delivered by AmPaM
and such Stockholder, (ii) a determination by an arbitration panel pursuant to
an arbitration conducted pursuant to Section 18.16 hereof or (iii) a
non-appealable judgment of a court of competent jurisdiction. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto. The covenants contained in Section 13
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
the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and pricing and cost
policies that are valuable, special and unique assets of the Company's, the
Other Founding Companies' and/or AmPaM'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 AmPaM, (b) following the
Closing, such information may be disclosed by the Stockholders as is required in
the course of performing their duties for AmPaM or the Company and (c) to its
counsel and other advisers, provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 14.1; provided, however
that (i) the foregoing disclosure prohibition shall not apply in the event that
(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 AmPaM and provide AmPaM 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, AmPaM 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 AmPaM from pursuing any other available remedy for such
breach or threatened breach, including the recovery of damages. In the event the
transactions contemplated


                                       48
<PAGE>   57


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 AmPaM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies that
are valuable, special and unique assets of the Company's business. AmPaM agrees
that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes known
to the public generally through no fault of AmPaM, (B) 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 (B), AmPaM
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 (C) 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 AmPaM of
the provisions of this Section 14.2, the Company and the Stockholders shall be
entitled to an injunction restraining AmPaM 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.
In the event the transactions contemplated by this Agreement are not consummated
for any reason, AmPaM shall nevertheless remain subject to this Section 14.2,
except that it shall not be permitted to make any disclosures otherwise than
pursuant to clause (A), (B) or (C) above.

         14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

         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 Closing Date.

         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AMPAM STOCK AND AMPAM NOTES. For
a period of two years from the Closing Date or, in the event that the Company
completes an IPO, for a period through the second anniversary of the date of the
closing of such IPO (the "Restricted Period"), no Stockholder shall (i) sell,
assign, exchange, transfer, pledge, or otherwise dispose of any shares of AmPaM
Stock or AmPaM Notes received by the Stockholders pursuant to this Agreement or
any securities convertible into, exchangeable or exercisable for any shares of
AmPaM Stock or AmPaM Notes received by such Stockholder pursuant to this
Agreement, (ii) grant any option to purchase, or otherwise enter into any
contract to sell, assign, transfer, pledge or otherwise dispose of, any shares
of AmPaM Stock or AmPaM Notes received by such Stockholder pursuant to this
Agreement, or (iii) enter into any swap or any other agreement or any
transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of the AmPaM Stock or AmPaM Notes, whether any
such swap or transaction is to be settled by delivery of shares of AmPaM Stock
or AmPaM Notes or other securities, by the delivery or payment of cash or
otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A) as
otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock, pursuant
to Section 17 hereof, (C) for transfers to (I) immediate family members of such
Stockholder who agree with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1, (II) trusts, limited partnerships or other estate
planning entities for the benefit of such Stockholder or family members of such
Stockholder which have agreed with AmPaM in writing, through action taken by the
trustees, partners or other persons having authority to bind the trust, limited
partnership or other estate planning entity, to be bound by the restrictions set
forth in this Section 15.1, (III) any charitable organization that qualifies for
receipt of charitable contributions under Section 170(c) of the Code which
agrees with AmPaM in writing to be bound by the restrictions set forth in this
Section 15.1, (D) for transfers of AmPaM Stock or AmPaM Notes to AmPaM pursuant
to Section 11.5(d), (E) for transfers to another Stockholder, to another person
or entity who receives shares of AmPaM Stock or AmPaM Notes or AmPaM Series A
Preferred Stock pursuant to the Other Agreements or to Sterling City Capital LLC
or any of its Affiliates provided that (1) such transaction is exempt from the
registration requirements of the 1933 Act as evidenced by the delivery to AmPaM
of an opinion of counsel in form and substance reasonably satisfactory to AmPaM
and (2) any such transferee agrees in writing to be bound by the restrictions
set forth in this Section 15.1, (F) transfers of shares of AmPaM Notes, shares
of AmPaM Stock, or grants of options to purchase shares of AmPaM Stock, by such
Stockholder to employees of the Company of up to an aggregate of 15% of the
shares of AmPaM Stock received by such Stockholder pursuant to this Agreement
provided that (1) any such transaction is exempt from the registration
requirements of the 1933 Act as evidenced by the delivery to AmPaM of an opinion
of counsel in form and substance reasonably satisfactory to AmPaM and (2) any
such employee agrees with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1 or (G) the sale by such Stockholder in an IPO of
shares of AmPaM Stock representing not more than 10% of the


                                       50
<PAGE>   59


Aggregate Consideration in cash; provided, however, that in no circumstance will
a Stockholder be entitled to sell shares of AmPaM Stock in an IPO to the extent
that the sale of such shares by such Stockholder would result in such
Stockholder receiving in excess of 45% of the Aggregate Consideration in cash;
and, provided further, if AmPaM 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 Section 17.1 that the number of
shares to be sold by persons other than AmPaM is greater than the number of such
shares which can be offered without adversely affecting the success of the
offering, AmPaM may reduce pro rata (among the Stockholders and all other
selling security holders in the offering) 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. During the
Restricted Period, the certificates evidencing the AmPaM Stock or AmPaM Notes
delivered to the Stockholders pursuant to Section 3 of this Agreement will bear
a legend substantially in the form set forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION
OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the shares
of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to be
delivered to such 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 sold, assigned, exchanged, transferred, pledged or
otherwise disposed of without compliance with the 1933 Act which, among other
matters, would require registration under the 1933 Act unless exemption from the
registration requirements is available for such transaction. The AmPaM Stock,
the Additional Consideration Right and any AmPaM Notes to be acquired by each
Stockholder pursuant to this Agreement is being acquired solely for such
Stockholder's own account, for investment purposes only, and with no present
intention of selling, assigning, exchanging, transferring, pledging, or
otherwise disposing of it. Each Stockholder covenants, warrants and represents
that neither the shares of AmPaM Stock, the Additional Consideration Right nor
any AmPaM Notes issued to such Stockholder will be offered, sold, assigned,
exchanged, pledged, 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 certificates representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision), and
is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of the
nature described in the preceding sentence and all questions have been answered
to such Stockholder's satisfaction. Except as set forth on Schedule 16.2, each
Stockholder is an "accredited investor" as defined in Rule 501(a) of the 1933
Act. Neither the foregoing nor any investigation made by the Stockholders
referred to above shall in any way affect the representations, warranties,
covenants and agreements of AmPaM made herein except to the extent that AmPaM is
relying upon the representations of the Stockholders in Section 16.1 and in this
Section 16.2 for purposes of


                                       52
<PAGE>   61


AmPaM's representations and warranties in Sections 6.9, 6.11, 6.15 and 6.17
hereof as specified therein.

         16.3 RELIANCE BY AmPaM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to register
any AmPaM Stock for its own or other's 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 AmPaM and (ii)
registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other distribution with respect
to, or in exchange for, or in replacement of such AmPaM Stock) which any such
Stockholder requests, other than shares of AmPaM Stock which may then be
immediately sold under Rule 144(k) (or any similar or successor provision)
promulgated under the 1933 Act, and other than shares of AmPaM Stock that have
been theretofore sold by the Stockholder in accordance with the 1933 Act,
provided that AmPaM shall have the right to reduce pro rata the number of shares
of each selling Stockholder included in such registration to the extent that
inclusion of such shares would, in the written opinion of tax counsel to AmPaM
or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Private Placement Memorandum as a tax-free
organization under Section 351 of the Code; provided, however, that with respect
to a proposal by AmPaM to register AmPaM Stock under the 1933 Act in connection
with an IPO, no Stockholder shall be permitted pursuant to this Section 17.1 to
have included in such registration more shares of AmPaM Stock than permitted to
be sold by such Stockholder pursuant to Section 15.1. In addition, if AmPaM 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 AmPaM is greater than the number of such shares which can be offered
without adversely affecting the success of the offering, AmPaM may reduce pro
rata (among the Stockholders and all other selling security holders in the
offering) 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. If any Stockholder disapproves of the terms of the
underwriting, that Stockholder may elect to withdraw therefrom by written notice
to AmPaM and the managing underwriter. That Stockholder's shares of AmPaM Stock
so withdrawn shall also be withdrawn from registration; provided, however, that,
if by the withdrawal of such shares a greater number of shares of AmPaM


                                       53
<PAGE>   62


Stock held by other Stockholders may be included in such registration, then
AmPaM shall offer to all other Stockholders of AmPaM the right to include
additional shares in the same proportion used in effecting the above
limitations. AmPaM shall not, for a period of two years following the Closing
Date, grant to any other person any rights to cause AmPaM to register any
securities in priority over, or in precedent to, the rights granted to the
Stockholders hereunder and to the stockholders of the Other Founding Companies
pursuant to Section 17 of the Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a representative of the
         Stockholders with copies of all such documents proposed to be filed) as
         promptly as practical;

                  (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such registration statement or supplement to the prospectus;

                  (iv) 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;

                  (v) Make "generally available to its security holders" (within
         the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;


                                       54
<PAGE>   63


                  (vi) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of the registration statement at
         the earliest possible moment;

                  (vii) If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment such
         information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM Stock being sold by
         participating Stockholders to any underwriter or underwriters, the
         purchase price being paid therefor by such underwriter or underwriters
         and with respect to any other terms of an underwritten offering of the
         shares of AmPaM Stock to be sold in such offering, and promptly make
         all required filings of such prospectus by supplement or post-effective
         amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition pursuant
         to such registration statement, and the counsel retained by the
         participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or any
         such underwriter (collectively, the "Inspectors"), all financial and
         other records, pertinent corporate documents and properties of AmPaM
         (the "Records"), as shall be reasonably necessary to enable them to
         exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x) 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 required to
         be kept effective, provided that AmPaM shall not be required to become
         subject to taxation, to qualify generally to do business or to file a
         general consent to service of process in any such states or
         jurisdictions;

                  (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any


                                       55
<PAGE>   64


         securities exchanges or trading systems on which similar securities
         issued by AmPaM are then listed or included; and

                  (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in effect),
         together with any associated term sheet, contains an untrue statement
         of a material fact or omits to state any fact required to be stated
         therein or necessary to make the statements therein (in the case of the
         prospectus or any preliminary prospectus, in light of the circumstances
         under which they were made) not misleading, and, at the request of such
         Stockholder, AmPaM promptly 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 required to be
         stated therein or necessary to make the statements therein (in the case
         of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall be
borne by AmPaM.

         17.3     INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue statement
of material fact contained or incorporated by reference in any registration
statement, prospectus or preliminary prospectus or associated term sheet or any
omission or alleged omission to state or incorporated by reference therein a
material fact required to be stated or incorporated by reference 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 AmPaM 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 AmPaM has furnished
such Indemnified Party with a sufficient number of copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning of
the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged


                                       56
<PAGE>   65


untrue statement of a material fact or any omission or alleged omission to state
therein a material fact required to be stated in the registration statement or
prospectus or any amendment thereof or supplement thereto or necessary to make
the statements therein not misleading, but only to the extent that such untrue
or alleged untrue statement or omission or alleged omission is contained in or
omitted from information so furnished in writing to AmPaM by such Stockholder
expressly for use in 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 hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i) each
participating Stockholder shall execute and deliver to AmPaM a written power of
attorney instrument that (A) appoints an officer of AmPaM as such Stockholder's
attorney-in-fact for purposes of executing and delivering an underwriting
agreement among AmPaM, the underwriters named therein and such Stockholder
specifying the terms and conditions applicable to the sale of AmPaM Stock of
such Stockholder in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering in which
one or more stockholders of the issuer are participants, including a provision
that authorizes the attorney-in-fact appointed by such Stockholder to execute
and deliver such an underwriting agreement in the event that the net price per
share to be received by such Stockholder from the sale of the shares of AmPaM
Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters


                                       57
<PAGE>   66


specifically for inclusion in any such registration statement and (B) such
Stockholder shall not be obligated to enter into such an underwriting agreement
in the event that the net price per share to be received by such Stockholder
from the sale of shares of AmPaM Stock to be sold in such offering is less than
the floor price specified in the power of attorney instrument executed and
delivered to AmPaM pursuant to clause (i) above.

         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares of
AmPaM Stock under this Agreement may be assigned to a transferee or assignee of
any Stockholder to the extent that such transferee or assignee is a member of
the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

                  (i) make and keep public information regarding AmPaM available
         as those terms are understood and defined in Rule 144 under the 1933
         Act beginning 90 days following the effective date of a registration
         statement relating to an IPO;

                  (ii) file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 AmPaM, 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.      REDEMPTION OF AMPAM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal payments,
if any, made with respect to AmPaM Notes held by such Stockholder) equal to or
exceeding 50% of the Aggregate Consideration on or prior to the third
anniversary of the Closing Date, such Stockholder shall have the right (the "Put
Right"), but not the


                                       58
<PAGE>   67


obligation, commencing on the third anniversary of the Closing Date to require
AmPaM to purchase a number of shares of AmPaM Stock then owned by such
Stockholder, subject to the limitations set forth in Section 18.2 below. The
purchase price for such redemption shall be $13.00 per share, such price to be
subject to appropriate adjustment to reflect any reclassification, stock
dividend, subdivision, split-up or combination of shares of AmPaM Stock after
the date hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified, AmPaM
shall be obligated to purchase from each eligible Stockholder no less than 10%
of the AmPaM Stock held by such Stockholder annually; provided, however, that
the Stockholders shall not be entitled to exercise their Put Rights if and to
the extent the Company has not achieved the Target Net Income (as defined in
Annex I hereto) for the year preceding the year in which a Stockholder seeks to
exercise his Put Right. The redemptions will be funded by internal cash flows or
alternative financing arrangements but AmPaM's obligation to make any redemption
pursuant to this Section 18 will be subject to the covenants and restrictions
contained in AmPaM's then existing private or public debt or equity instruments.

         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right by
giving written notice (the "Put Notice") to AmPaM within thirty (30) days of the
third anniversary of the execution hereof. If any Stockholder does not provide
AmPaM with a Put Notice within such thirty-day period, the Put Right applicable
to such Stockholder shall expire. The date for closing the sale of any shares of
AmPaM Stock pursuant to a proper exercise of a Put Right shall in no event be
earlier than 90 days after the date AmPaM receives the Put Notice. Any such
closing shall be at such time of day and place as shall be mutually agreed
between such holder and AmPaM. At such closing AmPaM shall make payment for the
AmPaM Stock to be repurchased by wire transfer of immediately available funds to
a bank account designated by such Stockholder for such purpose and such
Stockholder shall deliver to AmPaM certificates, duly endorsed for transfer,
representing the shares of AmPaM Stock to be purchased and sold pursuant to the
exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger or
consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any,


                                       59
<PAGE>   68


which are then held by persons other than the holders of AmPaM Common Stock as
of the Closing Date constitute 50% or more of AmPaM Common Stock outstanding as
of the date of the consummation of such transaction.

19.      GENERAL

         19.1 COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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
AmPaM on and after the Closing 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 Closing Date.

         19.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law and except as
provided in Section 17.5) and shall be binding upon and shall inure to the
benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

         19.3 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 and AmPaM 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 by
a written instrument executed by the Stockholders, the Company and AmPaM, 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.

         19.4 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. A telecopied
facsimile of an executed counterpart of this Agreement shall be sufficient to
evidence the binding agreement of each party to the terms hereof. However, each
party agrees to return to the other parties an original, duly executed
counterpart of this Agreement promptly after delivery of a telecopied facsimile
thereof.

         19.5 BROKERS AND AGENT. Except as disclosed on Schedule 18.5, each
party hereto 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

reimbursement and loan repayment obligation shall be limited to the foregoing
fees, expenses, and disbursements which are out-of-pocket expenses of AmPaM,
Sterling City Capital, LLC or any person or entity which is an Affiliate
thereof. Sterling City Capital, LLC shall be reimbursed by AmPaM in the form of
AmPaM Notes. AmPaM retains the right, within a reasonable period following the
Closing Date, to conduct an audit of the expenses for which Sterling City
Capital, LLC is reimbursed. Each Stockholder 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 purchase and sale of
the Company Stock, other than Transfer Taxes, if any, imposed by the State of

with respect to such Transfer Taxes. In addition, each Stockholder acknowledges
that he, and not the Company or AmPaM, will pay all Taxes due by him upon
receipt of the consideration payable pursuant to Section 1 hereof. The
Stockholders acknowledge that the risks of the transactions contemplated hereby
include Tax risks, with respect to which the Stockholders are relying
substantially on the opinion contemplated by Section 8.12 hereof and

herein, no delay of or omission in the exercise of any right, power or remedy
accruing to any party as a result of any breach or default by any other party
under this Agreement shall impair any such right, power or remedy, nor shall it
be construed as a waiver of or acquiescence in any such breach or default, or of
any similar breach or default occurring later; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
occurring before or after that waiver.

         19.11 TIME. Time is of the essence with respect to this Agreement.

         19.12 REFORMATION AND SEVERABILITY. In case any provision of this
Agreement shall be invalid, illegal or unenforceable, it shall, to the extent
possible, be modified in such manner as to be valid, legal and enforceable but

is not possible, such provision shall be severed from this Agreement, and in
either case the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby. No provision of this Agreement shall be interpreted or construed
against any party solely because that party or its legal representative drafted
such provision.

         19.13 REMEDIES CUMULATIVE. No right, remedy or election given by any

amendment or waiver effected in accordance with this Section 19.15 shall be
binding upon each of the parties hereto, any other person receiving AmPaM Stock
in connection with the purchase and sale of the Company Stock and each future
holder of such AmPaM Stock. Any

<PAGE>   72


consent of the Stockholders who would receive a majority of the Aggregate
Consideration pursuant to Section I of Annex I of this Agreement if the
transactions contemplated hereby were consummated shall be deemed to be the
consent of the Stockholders for purposes of provisions of this Agreement as to
which a consent of the Stockholders may be requested or required.

         19.16 MEDIATION AND ARBITRATION. If a dispute arises out of or relates
to this Agreement, or the breach thereof, and if said dispute cannot be settled
through direct discussions, the parties agree to first endeavor to settle the
dispute in an amicable manner by mediation administered by the American
Arbitration Association under its then prevailing Commercial Mediation Rules,
before resorting to arbitration. Thereafter, any unresolved controversy or claim
arising out of or relating to this Agreement, or the breach thereof, shall be
settled by arbitration administered by the American Arbitration Association in
accordance with its then prevailing Commercial Arbitration Rules. The
enforcement, interpretation and procedural and substantive effect of the
obligation to arbitrate created by this Section 19.16 shall be governed by the
Federal Arbitration Act as amended from time to time, 9 U.S.C. Section 1 et seq.
The parties hereby disclaim any intention to have the substantive or procedural
law of any state or other jurisdiction, other than the law of the United States
as embodied in the Federal Arbitration Act, applied to such obligation. Any such
mediation or arbitration proceeding will be conducted in Houston, Texas.

of AmPaM Stock issued and outstanding on the Closing Date that are owned by
Sterling City Capital, LLC, any Affiliates of Sterling City Capital, LLC and
the officers and directors of AmPaM will not be greater than the number of

forma adjustments utilized in the preparation of such pro forma financial
statements are reasonable, and such pro forma adjustments have been properly
applied to the historical financial amounts in the compilation of the pro forma
financial statements. Based on the representations in Section 5.9 of this

Placement Memorandum, as of the date of this Agreement, AmPaM has no material
liabilities or obligations of any kind, character or description, whether

Agreement and the Other Agreements and except for fees incurred in connection
with the transactions contemplated hereby and thereby.

and conditions set forth in applicable Federal, state and local statutes,
ordinances, permits, licenses, orders, approvals, variances, rules and
regulations and is not in violation, in any material respect, of any of the

         10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as
contemplated by this Agreement, after the Closing Date, AmPaM shall not and
shall not permit any of its Subsidiaries to undertake any act that would
jeopardize the tax-free status of the exchange of Company Stock for AmPaM Stock
(but not cash or other property), including without limitation:

                  (a) the retirement or reacquisition, directly or indirectly,
of all or part of the AmPaM Stock issued in connection with the transactions

benefit of the Stockholders other than as described in the Private Placement
Memorandum or as described in this Agreement.

         10.3 PREPARATION AND FILING OF TAX RETURNS; PAYMENT OF TAXES.

                  (a) The Company, if possible, or otherwise the Stockholders
shall file or cause to be filed all income Tax Returns (federal, state, local
or otherwise) of any Acquired Party for all taxable periods that end on or
before the Closing Date, and shall permit AmPaM to review all such Tax Returns
prior to such filings. Unless the Company is a C corporation, the Stockholders
shall pay or cause to be paid all income Tax liabilities (in excess of all
amounts already paid with respect thereto or properly accrued or reserved with
respect thereto on the Financial Statements) with respect to the Company's
operations for all periods through and including the Closing Date.

                  (b) AmPaM shall file or cause to be filed all separate
Returns of, or that include, any Acquired Party for all taxable periods ending
after the Closing Date.

                  (c) Unless required by applicable law, regulations or
government proceedings, AmPaM shall not take any action, including any
amendment of a Tax Return of any Acquired Party, if such action would result in
additional Tax liabilities payable by any of the Stockholders for periods
ending on or prior to the Closing Date.

                  (d) Each party hereto shall, and shall cause its subsidiaries
and Affiliates to, provide to each of the other parties hereto such cooperation
and information as any of them reasonably may request in 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 audit or other proceeding in
respect of Taxes. Such cooperation and information shall include providing
copies 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. Subject to the preceding sentence, each party required
to file Returns pursuant to this Agreement shall bear all costs of filing such
Returns.

<PAGE>   48


                  (e) Each of the Company, AmPaM and each Stockholder shall
comply with the tax reporting requirements of Section 1.351-3 of the 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.

         10.4 DIRECTORS. The persons named in the Private Placement Memorandum
shall be appointed as directors and elected as officers of AmPaM, as and to the
extent set forth in the Private Placement Memorandum, promptly following the
Closing Date; provided, however, that the parties hereto acknowledge that if
the Company consummates an IPO, the persons who will serve as directors and
executive officers of AmPaM will be adjusted as appropriate for a publicly
traded entity, with any such changes being subject to the approval of the
majority of the Board of Directors of AmPaM.

         10.5 LEGAL OPINIONS. If required by the lenders pursuant to the terms
of any agreements related to financing of the cash amounts referred to in

attached hereto as Annex V.

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

         11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS.

and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by AmPaM as a result of
or arising from (i) any breach of the representations and warranties of the

Memorandum and is contained in the Private Placement Memorandum, 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 required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that no Stockholder shall be liable
for any

                                      40

<PAGE>   49


indemnification obligation pursuant to this Section 11.1 in excess of such
Stockholder's pro rata share thereof determined by reference to the aggregate
value of the Base Cash Amount (as defined in Annex I of this Agreement), the
principal amount of AmPaM Notes and the shares of AmPaM Stock (valued at a
price of $13.00 per share) received by such Stockholder pursuant to Section
I.A. of Annex I hereto (without giving effect to the adjustments provided in
Sections I.B. and I.C. thereof) (giving effect to the value of such AmPaM Stock
and without giving effect to such adjustments, collectively, the "Aggregate
Consideration") such Stockholder would receive pursuant to Section I of Annex I
of this Agreement if the transactions contemplated hereby were consummated in
relation to the total Aggregate Consideration all Stockholders would receive
pursuant to Section I of Annex I of this Agreement if the transactions
contemplated hereby were consummated.

         (b) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement, from and against all claims, damages, actions,
suits, proceedings, demands, assessments, adjustments, costs and expenses

part of such Stockholder under this Agreement, or (iii) any liability under the
1933 Act or any Federal or state securities 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 solely to such Stockholder which was
based upon information provided to AmPaM or its counsel in writing by such
Stockholder specifically for inclusion in the Private Placement Memorandum and
is contained in the Private Placement Memorandum, 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 solely to such Stockholder
required to be stated therein or necessary to make the statements therein in
light of the circumstances in which such statements were made not misleading.

         (c) AmPaM acknowledges and agrees that other than the representations
and warranties of the Company or the Stockholders specifically contained in
this Agreement, there are no representations or warranties of the Company or
the Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

         11.2 INDEMNIFICATION BY AMPAM. AmPaM covenants and agrees that it will
indemnify, defend, protect and hold harmless the Company and the Stockholders
at all times from and after the date of this Agreement until the applicable

incurred by the Company or the Stockholders as a result of or arising from (i)
any breach by AmPaM of its representations and warranties set forth herein or
on the schedules attached

                                      41

<PAGE>   50


hereto or certificates delivered pursuant to this Agreement, (ii) any breach of
any agreement on the part of AmPaM under this Agreement; or (iii) any liability
under the 1933 Act or any Federal or state securities 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 contained in the Private Placement
Memorandum, 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
required to be stated therein or necessary to make the statements therein not
misleading, except to the extent such is based upon an untrue statement or
alleged untrue statement, or omission or alleged omission, made therein in
reliance upon, and in conformity with, the representations and warranties of
the Company or the Stockholders specifically contained in this Agreement or
other information furnished to AmPaM by the Company or the Stockholders in
writing specifically for inclusion therein.

         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim
by a person not a party to this Agreement ("Third Person"), or the commencement
of any action or proceeding by a Third Person, 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 reasonably
satisfactory to the Indemnified Party, 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 or
a conflict of interest is reasonably likely to arise that prevents counsel for
the Indemnifying Party from representing such 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, 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

                                      42

<PAGE>   51


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. 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 pay the Indemnified Party
for the settlement amount 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. With respect to any account, note or other
receivable as to which the Stockholders have paid in full any indemnification
obligation pursuant to this Section 11 as a result of a breach of the
representation and warranty made pursuant to Section 5.11 or as to which a
claim in respect thereof has been asserted pursuant to this Section 11 that has
been applied against the Indemnification Threshold with respect to the
Stockholders as a result of a breach of the representation and warranty made
pursuant to Section 5.11, AmPaM shall cause the Company to assign such account,
note or other receivable to the Stockholders. 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. 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 to this Agreement with respect to
any provision of this Agreement, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement. AmPaM hereby waives, to the fullest
extent permitted under applicable law, any and all other rights, claims and
causes of action, known or unknown, it or any indemnified person may have
against the Company or any Stockholder relating to this Agreement or the
transactions pursuant to this Agreement arising under or based upon any
Federal, state, local or foreign statute, law, rule, regulation or otherwise.
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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2

                                      43

<PAGE>   52


(calculated as provided in this Section 11.5) plus (iii) the principal amount
of the AmPaM Notes delivered to the Stockholders pursuant to Section 1.2, or
(b) $50,000 (the "Indemnification Threshold"). Stockholders shall not assert
any claim for indemnification hereunder against AmPaM until such time as, and
solely to the extent that, the aggregate of all claims which Stockholders may
have against AmPaM shall exceed $50,000; provided, however, that this sentence
shall not be applicable with respect of any failure by AmPaM to (i) deliver the
consideration specified in Annex I hereto on the Closing Date upon the
satisfaction, or waiver by AmPaM, of all conditions to the occurrence of the
Closing Date specified in Section 9 or (ii) comply with its obligations
pursuant to Section 10.1. After the $50,000 threshold for AmPaM (subject to the
proviso in the preceding sentence) or the Indemnification Threshold for a
Stockholder has been met, all claims must be made in $10,000 increments, which
claims may be cumulated in order to meet such $10,000 thresholds. For purposes
of this paragraph, the AmPaM Stock delivered to the Stockholders shall be
valued at $13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is
directly or indirectly related to a breach by such person of any
representation, warranty, covenant or other agreement set forth in this
Agreement. No claim for indemnification against the Stockholders shall limit,
diminish or change any obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at
$13.00 per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of
AmPaM Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration paid to such Stockholder by AmPaM to such Stockholder pursuant to
Annex I. For the purpose of crediting Stockholders for payments made to AmPaM
by means of delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued
at $13.00 per share.

         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary
of AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM

                                      44

<PAGE>   53


shall use commercially reasonable efforts to pursue any available insurance
coverage or other rights of indemnity or reimbursement from third parties with
respect to any such loss, liability or expense.

12.      TERMINATION OF AGREEMENT

         12.1 TERMINATION. This Agreement may be terminated at any time prior

                  (i) by mutual consent of AmPaM and the Stockholders;

                  (ii) by the Stockholders, if the transactions contemplated by
         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by the Company
         or the Stockholders prior to or on the Closing Date;

                  (iii) by AmPaM, if the transactions contemplated by this
         Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by AmPaM prior
         to or on the Closing Date;

                  (iv) by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein
         relating to AmPaM, and the curing of such default shall not have been
         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v) by AmPaM, if a material breach or default shall be made
         by the Company or the Stockholders in the observance or in the due and
         timely performance of any of the covenants or agreements contained

         such default shall not have been made (or in the reasonable judgment
         of AmPaM cannot be made) on or before the Closing Date;

                  (vi) by the Stockholders, if the conditions set forth in
         Section 8 hereof have not been satisfied or waived as of the Closing
         Date; or

                  (vii) by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2 PROCEDURE AND EFFECT OF TERMINATION. A determination to terminate
this Agreement by AmPaM pursuant to Section 12.1 shall be valid and effective

Agreement pursuant to Section 12.1, is given to the Stockholders in the manner

the giving of notice of termination of this Agreement pursuant to Section 12.1
as specified in the preceding sentence, this Agreement shall terminate, and the
transactions contemplated hereby shall be abandoned, without further action by
any of the parties hereto. Immediately upon any such termination, AmPaM shall

shall have any liability or further obligation hereunder to any other party,
except as provided in Section 14 and Section 18.6, provided, that, 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 that occurred prior to such termination.

         the Company has in the past disclosed such information to the public
         for valid business reasons; or

                  (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

         13.2 DAMAGES. Because of the difficulty of measuring economic losses
to AmPaM as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to AmPaM for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by AmPaM 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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement
or otherwise, shall not constitute a defense to the enforcement by AmPaM of
such covenants. It is specifically agreed that the period of two (2) 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 found to be in violation of any provision of this Section 13 as
determined by any of (i) a written agreement to such effect executed and
delivered by AmPaM and such Stockholder, (ii) a determination by an arbitration
panel pursuant to an arbitration conducted pursuant to Section 18.16 hereof or
(iii) a non-appealable judgment of a court of competent jurisdiction. The
covenants contained in Section 13 shall not be affected by any breach of any
other provision hereof by any party hereto. The covenants contained in Section
13 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
the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and
pricing and cost policies that are valuable, special and unique assets of the
Company's, the Other Founding Companies' and/or AmPaM'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
AmPaM, (b) following the Closing, such information may be disclosed by the
Stockholders as is required in the course of performing their duties for AmPaM
or the Company and (c) to its counsel and other advisers, provided that such
advisers (other than counsel) agree to the confidentiality provisions of this
Section 14.1; provided, however that (i) the foregoing disclosure prohibition
shall not apply in the event that (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
AmPaM and provide AmPaM 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, AmPaM 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
AmPaM from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages. In the event the transactions
contemplated

                                      48

<PAGE>   57


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 AmPaM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies
that are valuable, special and unique assets of the Company's business. AmPaM
agrees that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes
known to the public generally through no fault of AmPaM, (B) 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 (B),
AmPaM 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 (C) 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 AmPaM of the provisions of this Section 14.2, the Company and the
Stockholders shall be entitled to an injunction restraining AmPaM 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. In the event the transactions contemplated
by this Agreement are not consummated for any reason, AmPaM shall nevertheless
remain subject to this Section 14.2, except that it shall not be permitted to
make any disclosures otherwise than pursuant to clause (A), (B) or (C) above.

         14.3 DAMAGES. Because of the difficulty of measuring economic losses
as a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the
covenant may be enforced against the other parties by injunctions and
restraining orders.

         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 Closing Date.

                                      49

<PAGE>   58


         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AMPAM STOCK AND AMPAM NOTES.
For a period of two years from the Closing Date or, in the event that the
Company completes an IPO, for a period through the second anniversary of the
date of the closing of such IPO (the "Restricted Period"), no Stockholder shall
(i) sell, assign, exchange, transfer, pledge, or otherwise dispose of any

this Agreement or any securities convertible into, exchangeable or exercisable
for any shares of AmPaM Stock or AmPaM Notes received by such Stockholder
pursuant to this Agreement, (ii) grant any option to purchase, or otherwise
enter into any contract to sell, assign, transfer, pledge or otherwise dispose
of, any shares of AmPaM Stock or AmPaM Notes received by such Stockholder
pursuant to this Agreement, or (iii) enter into any swap or any other agreement
or any transaction that transfers, in whole or in part, directly or indirectly,
the economic consequence of ownership of the AmPaM Stock or AmPaM Notes,
whether any such swap or transaction is to be settled by delivery of shares of
AmPaM Stock or AmPam Notes or other securities, by the delivery or payment of
cash or otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A)
as otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock,
pursuant to Section 17 hereof, (C) for transfers to (I) immediate family
members of such Stockholder who agree with AmPaM in writing to be bound by the
restrictions set forth in this Section 15.1, (II) trusts, limited partnerships
or other estate planning entities for the benefit of such Stockholder or family
members of such Stockholder which have agreed with AmPaM in writing, through
action taken by the trustees, partners or other persons having authority to
bind the trust, limited partnership or other estate planning entity, to be
bound by the restrictions set forth in this Section 15.1, (III) any charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code which agrees with AmPaM in writing to be bound by
the restrictions set forth in this Section 15.1, (D) for transfers of AmPaM
Stock or AmPaM Notes to AmPaM pursuant to Section 11.5(d), (E) for transfers to
another Stockholder, to another person or entity who receives shares of AmPaM
Stock or AmPaM Notes or AmPaM Series A Preferred Stock pursuant to the Other
Agreements or to Sterling City Capital LLC or any of its Affiliates provided
that (1) such transaction is exempt from the registration requirements of the
1933 Act as evidenced by the delivery to AmPaM of an opinion of counsel in form
and substance reasonably satisfactory to AmPaM and (2) any such transferee
agrees in writing to be bound by the restrictions set forth in this Section
15.1, (F) transfers of shares of AmPaM Notes, shares of AmPaM Stock, or grants
of options to purchase shares of AmPaM Stock, by such Stockholder to employees
of the Company of up to an aggregate of 15% of the shares of AmPaM Stock
received by such Stockholder pursuant to this Agreement provided that (1) any
such transaction is exempt from the registration requirements of the 1933 Act
as evidenced by the delivery to AmPaM of an opinion of counsel in form and
substance reasonably satisfactory to AmPaM and (2) any such employee agrees
with AmPaM in writing to be bound by the restrictions set forth in this Section
15.1 or (G) the sale by such Stockholder in an IPO of shares of AmPaM Stock
representing not more than 10% of the Aggregate Consideration in cash;
provided,

                                      50

<PAGE>   59


however, that in no circumstance will a Stockholder be entitled to sell shares
of AmPaM Stock in an IPO to the extent that the sale of such shares by such
Stockholder would result in such Stockholder receiving in excess of 45% of the
Aggregate Consideration in cash; and, provided further, if AmPaM 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
Section 17.1 that the number of shares to be sold by persons other than AmPaM
is greater than the number of such shares which can be offered without
adversely affecting the success of the offering, AmPaM may reduce pro rata
(among the Stockholders and all other selling security holders in the offering)
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. During the Restricted Period, the certificates evidencing
the AmPaM Stock or AmPaM Notes delivered to the Stockholders pursuant to
Section 3 of this Agreement will bear a legend substantially in the form set
forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION
OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the
shares of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes
to be delivered to such 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 sold, assigned, exchanged, transferred,
pledged or otherwise disposed of without compliance with the 1933 Act which,
among other matters, would require registration under the 1933 Act unless
exemption from the registration requirements is available for such transaction.
The AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to be
acquired by each Stockholder pursuant to this Agreement is being acquired
solely for such Stockholder's own account, for investment purposes only, and
with no present intention of selling, assigning, exchanging, transferring,
pledging, or otherwise disposing of it. Each Stockholder covenants, warrants
and represents that neither the shares of AmPaM Stock, the Additional
Consideration Right nor any AmPaM Notes issued to such Stockholder will be
offered, sold, assigned, exchanged, pledged, 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 certificates
representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision),
and is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of
the nature described in the preceding sentence and all questions have been
answered to such Stockholder's satisfaction. Except as set forth on Schedule
16.2, each Stockholder is an "accredited investor" as defined in Rule 501(a) of
the 1933 Act. Neither the foregoing nor any investigation made by the
Stockholders referred to above shall in any way affect the representations,
warranties, covenants and agreements of AmPaM made herein except to the extent
that AmPaM is relying upon the representations of the Stockholders in Section
16.1 and in this Section 16.2 for purposes of

                                       52

<PAGE>   61


AmPaM's representations and warranties in Sections 6.9, 6.11, 6.15 and 6.17
hereof as specified therein.

         16.3 RELIANCE BY AmPaM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to
register any AmPaM Stock for its own or other's 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 AmPaM and
(ii) registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other
distribution with respect to, or in exchange for, or in replacement of such
AmPaM Stock) which any such Stockholder requests, other than shares of AmPaM
Stock which may then be immediately sold under Rule 144(k) (or any similar or
successor provision) promulgated under the 1933 Act, and other than shares of
AmPaM Stock that have been theretofore sold by the Stockholder in accordance
with the 1933 Act, provided that AmPaM shall have the right to reduce pro rata
the number of shares of each selling Stockholder included in such registration
to the extent that inclusion of such shares would, in the written opinion of
tax counsel to AmPaM or its independent auditors, jeopardize the status of the
transactions contemplated hereby and by the Private Placement Memorandum as a
tax-free organization under Section 351 of the Code; provided, however, that
with respect to a proposal by AmPaM to register AmPaM Stock under the 1933 Act
in connection with an IPO, no Stockholder shall be permitted pursuant to this
Section 17.1 to have included in such registration more shares of AmPaM Stock
than permitted to be sold by such Stockholder pursuant to Section 15.1. In
addition, if AmPaM 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 AmPaM is greater than the number of
such shares which can be offered without adversely affecting the success of the
offering, AmPaM may reduce pro rata (among the Stockholders and all other
selling security holders in the offering) 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. If any
Stockholder disapproves of the terms of the underwriting, that Stockholder may
elect to withdraw therefrom by written notice to AmPaM and the managing
underwriter. That Stockholder's shares of AmPaM Stock so withdrawn shall also
be withdrawn from registration; provided, however, that, if by the withdrawal
of such shares a greater number of shares of AmPaM

                                      53

<PAGE>   62


Stock held by other Stockholders may be included in such registration, then
AmPaM shall offer to all other Stockholders of AmPaM the right to include
additional shares in the same proportion used in effecting the above
limitations. AmPaM shall not, for a period of two years following the Closing
Date, grant to any other person any rights to cause AmPaM to register any
securities in priority over, or in precedent to, the rights granted to the
Stockholders hereunder and to the stockholders of the Other Founding Companies
pursuant to Section 17 of the Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a
         representative of the Stockholders with copies of all such documents
         proposed to be filed) as promptly as practical;

                  (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth
         in such registration statement or supplement to the prospectus;

                  (iv) 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;

                  (v) Make "generally available to its security holders"
         (within the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;

                                       54

<PAGE>   63


                  (vi) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of the registration statement
         at the earliest possible moment;

                  (vii) If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment
         such information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM Stock being sold by
         participating Stockholders to any underwriter or underwriters, the
         purchase price being paid therefor by such underwriter or underwriters
         and with respect to any other terms of an underwritten offering of the
         shares of AmPaM Stock to be sold in such offering, and promptly make
         all required filings of such prospectus by supplement or
         post-effective amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition
         pursuant to such registration statement, and the counsel retained by
         the participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or
         any such underwriter (collectively, the "Inspectors"), all financial
         and other records, pertinent corporate documents and properties of
         AmPaM (the "Records"), as shall be reasonably necessary to enable them
         to exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x) 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 required to be kept effective, provided that
         AmPaM shall not be required to become subject to taxation, to qualify
         generally to do business or to file a general consent to service of
         process in any such states or jurisdictions;

                  (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any

                                       55

<PAGE>   64


         securities exchanges or trading systems on which similar securities
         issued by AmPaM are then listed or included; and

                  (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in
         effect), together with any associated term sheet, contains an untrue
         statement of a material fact or omits to state any fact required to be
         stated therein or necessary to make the statements therein (in the
         case of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading, and, at the
         request of such Stockholder, AmPaM promptly 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
         required to be stated therein or necessary to make the statements
         therein (in the case of the prospectus or any preliminary prospectus,
         in light of the circumstances under which they were made) not
         misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall
be borne by AmPaM.

         17.3     INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue
statement of material fact contained or incorporated by reference in any
registration statement, prospectus or preliminary prospectus or associated term
sheet or any omission or alleged omission to state or incorporated by reference
therein a material fact required to be stated or incorporated by reference
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 AmPaM 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 AmPaM has furnished such Indemnified Party with a sufficient number of
copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning
of the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged

                                       56

<PAGE>   65


untrue statement of a material fact or any omission or alleged omission to
state therein a material fact required to be stated in the registration
statement or prospectus or any amendment thereof or supplement thereto or
necessary to make the statements therein not misleading, but only to the extent
that such untrue or alleged untrue statement or omission or alleged omission is
contained in or omitted from information so furnished in writing to AmPaM by
such Stockholder expressly for use in 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 hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i)
each participating Stockholder shall execute and deliver to AmPaM a written
power of attorney instrument that (A) appoints an officer of AmPaM as such
Stockholder's attorney-in-fact for purposes of executing and delivering an
underwriting agreement among AmPaM, the underwriters named therein and such
Stockholder specifying the terms and conditions applicable to the sale of AmPaM
Stock of such Stockholder in such offering and (B) otherwise is in such form
and containing such provisions as are customary in the securities business for
such an arrangement in connection with an underwritten registered offering in
which one or more stockholders of the issuer are participants, including a
provision that authorizes the attorney-in-fact appointed by such Stockholder to
execute and deliver such an underwriting agreement in the event that the net
price per share to be received by such Stockholder from the sale of the shares
of AmPaM Stock to be sold in such offering is not less than a price specified
in such instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters

                                       57

<PAGE>   66


specifically for inclusion in any such registration statement and (B) such
Stockholder shall not be obligated to enter into such an underwriting agreement
in the event that the net price per share to be received by such Stockholder
from the sale of shares of AmPaM Stock to be sold in such offering is less than
the floor price specified in the power of attorney instrument executed and
delivered to AmPaM pursuant to clause (i) above.

         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares
of AmPaM Stock under this Agreement may be assigned to a transferee or assignee
of any Stockholder to the extent that such transferee or assignee is a member
of the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

                  (i) make and keep public information regarding AmPaM
         available as those terms are understood and defined in Rule 144 under
         the 1933 Act beginning 90 days following the effective date of a
         registration statement relating to an IPO;

                  (ii) file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current
         public information requirements of Rule 144 (at any time from and
         after 90 days following the effective date of a registration statement
         relating to an IPO), 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 AmPaM, 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.      REDEMPTION OF AMPAM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal
payments, if any, made with respect to AmPaM Notes held by such Stockholder)
equal to or exceeding 50% of the Aggregate Consideration on or prior to the
third anniversary of the Closing Date, such Stockholder shall have the right
(the "Put Right"), but not the

                                       58

<PAGE>   67


obligation, commencing on the third anniversary date of the Closing Date to
require AmPaM to purchase a number of shares of AmPaM Stock then owned by such
Stockholder, subject to the limitations set forth in Section 18.2 below. The
purchase price for such redemption shall be $13.00 per share, such price to be
subject to appropriate adjustment to reflect any reclassification, stock
dividend, subdivision, split-up or combination of shares of AmPaM Stock after
the date hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified,
AmPaM shall be obligated to purchase from each eligible Stockholder no less
than 10% of the AmPaM Stock held by such Stockholder annually; provided,
however, that the Stockholders shall not be entitled to exercise their Put
Rights if and to the extent the Company has not achieved the Target Net Income
(as defined in Annex I hereto) for the year preceding the year in which a
Stockholder seeks to exercise his Put Right. The redemptions will be funded by
internal cash flows or alternative financing arrangements but AmPaM's
obligation to make any redemption pursuant to this Section 18 will be subject
to the covenants and restrictions contained in AmPaM's then existing private or
public debt or equity instruments.

         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right
by giving written notice (the "Put Notice") to AmPaM within thirty (30) days of
the third anniversary of the execution hereof. If any Stockholder does not
provide AmPaM with a Put Notice within such thirty-day period, the Put Right
applicable to such Stockholder shall expire. The date for closing the sale of
any shares of AmPaM Stock pursuant to a proper exercise of a Put Right shall in
no event be earlier than 90 days after the date AmPaM receives the Put Notice.
Any such closing shall be at such time of day and place as shall be mutually
agreed between such holder and AmPaM. At such closing AmPaM shall make payment
for the AmPaM Stock to be repurchased by wire transfer of immediately available
funds to a bank account designated by such Stockholder for such purpose and
such Stockholder shall deliver to AmPaM certificates, duly endorsed for
transfer, representing the shares of AmPaM Stock to be purchased and sold
pursuant to the exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger
or consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any,

                                       59

<PAGE>   68


which are then held by persons other than the holders of AmPaM Common Stock as
of the Closing Date constitute 50% or more of AmPaM Common Stock outstanding as
of the date of the consummation of such transaction.

19.      GENERAL

         19.1 COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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 AmPaM on and after the Closing 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 Closing Date.

         19.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law and except as
provided in Section 17.5) and shall be binding upon and shall inure to the
benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

         19.3 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 and AmPaM 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 by
a written instrument executed by the Stockholders, the Company and AmPaM,
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.

         19.4 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. A
telecopied facsimile of an executed counterpart of this Agreement shall be
sufficient to evidence the binding agreement of each party to the terms hereof.
However, each party agrees to return to the other parties an original, duly
executed counterpart of this Agreement promptly after delivery of a telecopied
facsimile thereof.

party hereto represents and warrants that it employed no broker or agent in

AmPaM funds to pay any such fees, expenses and disbursements, provided that
such reimbursement and loan repayment obligation shall be limited to the
foregoing fees, expenses, and disbursements which are out-of-pocket expenses of
AmPaM, Sterling City Capital, LLC or any person or entity which is an Affiliate

AmPaM Notes. AmPaM retains the right, within a reasonable period following the

Capital, LLC is reimbursed. Each Stockholder shall pay all sales, use,
transfer, real property transfer, recording, gains, stock transfer and other

all Taxes due by him upon receipt of the consideration payable pursuant to
Section 1 hereof. The Stockholders acknowledge that the risks of the
transactions contemplated hereby include Tax risks, with respect to which the
Stockholders are relying substantially on the opinion contemplated by Section

herein, no delay of or omission in the exercise of any right, power or remedy
accruing to any party as a result of any breach or default by any other party
under this Agreement shall impair any such right, power or remedy, nor shall it
be construed as a waiver of or acquiescence in any such breach or default, or
of any similar breach or default occurring later; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
occurring before or after that waiver.

         19.11 TIME. Time is of the essence with respect to this Agreement.

         19.12 REFORMATION AND SEVERABILITY. In case any provision of this
Agreement shall be invalid, illegal or unenforceable, it shall, to the extent
possible, be modified in such manner as to be valid, legal and enforceable but
so as to most nearly retain the intent of the parties, and if such modification
is not possible, such provision shall be severed from this Agreement, and in
either case the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby. No provision of this Agreement shall be interpreted or construed
against any party solely because that party or its legal representative drafted
such provision.

consummated. Any amendment or waiver effected in accordance with this Section
19.15 shall be binding upon each of the parties hereto, any other person
receiving AmPaM Stock in connection with the purchase and sale of the Company

         19.16 MEDIATION AND ARBITRATION. If a dispute arises out of or relates
to this Agreement, or the breach thereof, and if said dispute cannot be settled
through direct discussions, the parties agree to first endeavor to settle the
dispute in an amicable manner by mediation administered by the American
Arbitration Association under its then prevailing Commercial Mediation Rules,
before resorting to arbitration. Thereafter, any unresolved controversy or
claim arising out of or relating to this Agreement, or the breach thereof,
shall be settled by arbitration administered by the American Arbitration
Association in accordance with its then prevailing Commercial Arbitration
Rules. The enforcement, interpretation and procedural and substantive effect of
the obligation to arbitrate created by this Section 19.16 shall be governed by
the Federal Arbitration Act as amended from time to time, 9 U.S.C. Section 1 et
seq. The parties hereby disclaim any intention to have the substantive or
procedural law of any state or other jurisdiction, other than the law of the
United States as embodied in the Federal Arbitration Act, applied to such
obligation. Any such mediation or arbitration proceeding will be conducted in
Houston, Texas.

stock of AmPaM have been duly authorized and validly issued, are fully paid and
nonassessable and such shares were offered, issued, sold and delivered by AmPaM
in compliance with all applicable state and Federal laws concerning the

of the preemptive rights of any past or present stockholder of AmPaM. Upon the
Closing Date, the authorized, issued and outstanding shares of capital stock of
AmPaM will be as set forth in the Private Placement Memorandum under the
caption "Capitalization." Upon the Closing Date, the aggregate number of shares
of AmPaM Stock issued and outstanding on the Closing Date that are owned by
Sterling City Capital, LLC, any Affiliates of Sterling City Capital, LLC and
the officers and directors of AmPaM will not be greater than the number of
shares of AmPaM Stock reflected in the Private Placement Memorandum as the

compensation plan for the benefit of certain employees as described in Annex I

included in the Private Placement Memorandum (the "AmPaM Financial Statements")
have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods indicated (except as noted thereon), and the balance
sheet included therein presents fairly the financial position of AmPaM as of

statements are reasonable, and such pro forma adjustments have been properly
applied to the historical financial amounts in the compilation of the pro forma
financial statements. Based on the representations in Section 5.9 of this

financial information of AmPaM fairly presents the pro forma financial
position, results of operations and other information purported to be shown
therein at the respective dates and for the respective periods specified.

Placement Memorandum, as of the date of this Agreement, AmPaM has no material
liabilities or obligations of any kind, character or description, whether

Agreement and the Other Agreements and except for fees incurred in connection
with the transactions contemplated hereby and thereby.

         10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as

jeopardize the tax-free status of the exchange of Company Stock for AmPaM Stock
(but not cash or other property), including without limitation:

              (a) the retirement or reacquisition, directly or indirectly, of
all or part of the AmPaM Stock issued in connection with the transactions

              (a) The Company, if possible, or otherwise the Stockholders shall
file or cause to be filed all income Tax Returns (federal, state, local or
otherwise) of any Acquired Party for all taxable periods that end on or before
the Closing Date, and shall permit AmPaM to review all such Tax Returns prior
to such filings. Unless the Company is a C corporation, the Stockholders shall

thereto on the Financial Statements) with respect to the Company's operations
for all periods through and including the Closing Date.

              (b) AmPaM shall file or cause to be filed all separate Returns

              (c) Unless required by applicable law, regulations or government
proceedings, AmPaM shall not take any action, including any amendment of a Tax
Return of any Acquired Party, if such action would result in additional Tax
liabilities payable by any of the Stockholders for periods ending on or prior
to the Closing Date.

              (d) Each party hereto shall, and shall cause its subsidiaries and
Affiliates to, provide to each of the other parties hereto such cooperation and

refund of Taxes or in conducting any audit or other proceeding in respect of
Taxes. Such cooperation and information shall include providing copies 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.
Subject to the preceding sentence, each party required to file Returns pursuant
to this Agreement shall bear all costs of filing such Returns.

              (e) Each of the Company, AmPaM and each Stockholder shall comply
with the tax reporting requirements of Section 1.351-3 of the 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.

         10.4 DIRECTORS. The persons named in the Private Placement Memorandum
shall be appointed as directors and elected as officers of AmPaM, as and to the
extent set forth in the Private Placement Memorandum, promptly following the
Closing Date; provided, however, that the parties hereto acknowledge that if
the Company consummates an IPO, the persons who will serve as directors and
executive officers of AmPaM will be adjusted as appropriate for a publicly
traded entity, with any such changes being subject to the approval of the
majority of the Board of Directors of AmPaM.

         10.5 LEGAL OPINIONS. If required by the lenders pursuant to the terms

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

and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) incurred by AmPaM as a result of
or arising from (i) any breach of the representations and warranties of the
Company set forth herein or on the schedules attached hereto or certificates

writing by the Company specifically for inclusion in the Private Placement
Memorandum and is contained in the Private Placement Memorandum, 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 required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that no Stockholder shall be liable
for any


                                       40

<PAGE>   49


indemnification obligation pursuant to this Section 11.1 in excess of such
Stockholder's pro rata share thereof determined by reference to the aggregate
value of the Base Cash Amount (as defined in Annex I of this Agreement), the
principal amount of AmPaM Notes and the shares of AmPaM Stock (valued at a
price of $13.00 per share) received by such Stockholder pursuant to Section
I.A. of Annex I hereto (without giving effect to the adjustments provided in
Sections I.B. and I.C. thereof) (giving effect to the value of such AmPaM Stock
and without giving effect to such adjustments, collectively, the "Aggregate
Consideration") such Stockholder would receive pursuant to Section I of Annex I
of this Agreement if the transactions contemplated hereby were consummated in
relation to the total Aggregate Consideration all Stockholders would receive
pursuant to Section I of Annex I of this Agreement if the transactions
contemplated hereby were consummated.

         (b) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement, from and against all claims, damages, actions,
suits, proceedings, demands, assessments, adjustments, costs and expenses

otherwise, arising out of or based upon any untrue statement or alleged untrue
statement of a material fact relating solely to such Stockholder which was
based upon information provided to AmPaM or its counsel in writing by such
Stockholder specifically for inclusion in the Private Placement Memorandum and
is contained in the Private Placement Memorandum, 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 solely to such Stockholder
required to be stated therein or necessary to make the statements therein in
light of the circumstances in which such statements were made not misleading.

         (c) AmPaM acknowledges and agrees that other than the representations
and warranties of the Company or the Stockholders specifically contained in
this Agreement, there are no representations or warranties of the Company or
the Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

         11.2 INDEMNIFICATION BY AmPaM. AmPaM covenants and agrees that it will
indemnify, defend, protect and hold harmless the Company and the Stockholders
at all times from and after the date of this Agreement until the applicable

provided that for purposes of clause (iii) below, the applicable Expiration

from and against all claims, damages, actions, suits, proceedings, demands,

without limitation, reasonable attorneys' fees and expenses of investigation)
incurred by the Company or the Stockholders as a result of or arising from (i)
any breach by AmPaM of its representations and warranties set forth herein or
on the schedules attached


                                       41

<PAGE>   50


hereto or certificates delivered pursuant to this Agreement, (ii) any breach of
any agreement on the part of AmPaM under this Agreement; or (iii) any liability
under the 1933 Act or any Federal or state securities 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 contained in the Private Placement
Memorandum, 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
required to be stated therein or necessary to make the statements therein not
misleading, except to the extent such is based upon an untrue statement or
alleged untrue statement, or omission or alleged omission, made therein in
reliance upon, and in conformity with, the representations and warranties of
the Company or the Stockholders specifically contained in this Agreement or
other information furnished to AmPaM by the Company or the Stockholders in
writing specifically for inclusion therein.

         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim
by a person not a party to this Agreement ("Third Person"), or the commencement
of any action or proceeding by a Third Person, 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 reasonably
satisfactory to the Indemnified Party, 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 or
a conflict of interest is reasonably likely to arise that prevents counsel for
the Indemnifying Party from representing such 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, 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


                                       42



<PAGE>   51


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. 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 pay the Indemnified Party
for the settlement amount 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. With respect to any account, note or other
receivable as to which the Stockholders have paid in full any indemnification
obligation pursuant to this Section 11 as a result of a breach of the
representation and warranty made pursuant to Section 5.11 or as to which a
claim in respect thereof has been asserted pursuant to this Section 11 that has
been applied against the Indemnification Threshold with respect to the
Stockholders as a result of a breach of the representation and warranty made
pursuant to Section 5.11, AmPaM shall cause the Company to assign such account,
note or other receivable to the Stockholders. 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. 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 to this Agreement with respect to
any provision of this Agreement, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement. AmPaM hereby waives, to the fullest
extent permitted under applicable law, any and all other rights, claims and
causes of action, known or unknown, it or any indemnified person may have
against the Company or any Stockholder relating to this Agreement or the
transactions pursuant to this Agreement arising under or based upon any
Federal, state, local or foreign statute, law, rule, regulation or otherwise.
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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2


                                       43

<PAGE>   52


(calculated as provided in this Section 11.5) plus (iii) the principal amount
of the AmPaM Notes delivered to the Stockholders pursuant to Section 1.2, or
(b) $50,000 (the "Indemnification Threshold"). Stockholders shall not assert
any claim for indemnification hereunder against AmPaM until such time as, and
solely to the extent that, the aggregate of all claims which Stockholders may
have against AmPaM shall exceed $50,000; provided, however, that this sentence
shall not be applicable with respect of any failure by AmPaM to (i) deliver the
consideration specified in Annex I hereto on the Closing Date upon the
satisfaction, or waiver by AmPaM, of all conditions to the occurrence of the
Closing Date specified in Section 9 or (ii) comply with its obligations
pursuant to Section 10.1. After the $50,000 threshold for AmPaM (subject to the
proviso in the preceding sentence) or the Indemnification Threshold for a
Stockholder has been met, all claims must be made in $10,000 increments, which
claims may be cumulated in order to meet such $10,000 thresholds. For purposes
of this paragraph, the AmPaM Stock delivered to the Stockholders shall be
valued at $13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is
directly or indirectly related to a breach by such person of any
representation, warranty, covenant or other agreement set forth in this
Agreement. No claim for indemnification against the Stockholders shall limit,
diminish or change any obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at
$13.00 per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of
AmPaM Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration paid to such Stockholder by AmPaM to such Stockholder pursuant to
Annex I. For the purpose of crediting Stockholders for payments made to AmPaM
by means of delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued
at $13.00 per share.

         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary
of AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM shall use commercially reasonable
efforts to pursue any available insurance coverage or other rights of indemnity
or reimbursement from third parties with respect to any such loss, liability or
expense.

         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions

         Agreement to take place at the Closing Date shall not have been

         to or on the Closing Date;

              (iv) by the Stockholders, if a material breach or default shall
         be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein

         made) on or before the Closing Date;

              (v) by AmPaM, if a material breach or default shall be made by
         the Company or the Stockholders in the observance or in the due and

              (vi) by the Stockholders, if the conditions set forth in Section
         8 hereof have not been satisfied or waived as of the Closing Date; or

              (vii) by AmPaM, if the conditions set forth in Section 9 hereof

contained in this Agreement including, but not limited to, legal and audit
costs and out of pocket expenses that occurred prior to such termination.

         of such Stockholder after due inquiry, AmPaM or any subsidiary thereof
         made an acquisition analysis, for the purpose of acquiring such
         entity; or

              (v) disclose to any person, firm, partnership, corporation or
         business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or
         any of its subsidiaries within the two (2) years prior to the Closing
         Date for any reason or purpose whatsoever except to the extent that
         the Company has in the past disclosed such information to the public
         for valid business reasons; or

              (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

         13.2 DAMAGES. Because of the difficulty of measuring economic losses
to AmPaM as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to AmPaM for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by AmPaM 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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement
or otherwise, shall not constitute a defense to the enforcement by AmPaM of
such covenants. It is specifically agreed that the period of two (2) 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 found to be in violation of any provision of this Section 13 as
determined by any of (i) a written agreement to such effect executed and
delivered by AmPaM and such Stockholder, (ii) a determination by an arbitration
panel pursuant to an arbitration conducted pursuant to Section 18.16 hereof or
(iii) a non-appealable judgment of a court of competent jurisdiction. The
covenants contained in Section 13 shall not be affected by any breach of any
other provision hereof by any party hereto. The covenants contained in Section
13 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
the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and
pricing and cost policies that are valuable, special and unique assets of the
Company's, the Other Founding Companies' and/or AmPaM'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
AmPaM, (b) following the Closing, such information may be disclosed by the
Stockholders as is required in the course of performing their duties for AmPaM
or the Company and (c) to its counsel and other advisers, provided that such
advisers (other than counsel) agree to the confidentiality provisions of this
Section 14.1; provided, however that (i) the foregoing disclosure prohibition
shall not apply in the event that (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
AmPaM and provide AmPaM 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, AmPaM 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
AmPaM from pursuing any other available remedy for such breach or threatened
breach, including the recovery of damages. In the event the transactions
contemplated

                                       48

<PAGE>   57
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 AmPaM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies
that are valuable, special and unique assets of the Company's business. AmPaM
agrees that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes
known to the public generally through no fault of AmPaM, (B) 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 (B),
AmPaM 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 (C) 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 AmPaM of the provisions of this Section 14.2, the Company and the
Stockholders shall be entitled to an injunction restraining AmPaM 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. In the event the transactions contemplated
by this Agreement are not consummated for any reason, AmPaM shall nevertheless
remain subject to this Section 14.2, except that it shall not be permitted to
make any disclosures otherwise than pursuant to clause (A), (B) or (C) above.

         14.3 DAMAGES. Because of the difficulty of measuring economic losses
as a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the
covenant may be enforced against the other parties by injunctions and
restraining orders.

         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 Closing Date.


                                       49

<PAGE>   58


         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AmPaM STOCK AND AmPaM NOTES.
For a period of two years from the Closing Date or, in the event that the
Company completes an IPO, for a period through the second anniversary of the
date of the closing of such IPO (the "Restricted Period"), no Stockholder shall
(i) sell, assign, exchange, transfer, pledge, or otherwise dispose of any

this Agreement or any securities convertible into, exchangeable or exercisable
for any shares of AmPaM Stock or AmPaM Notes received by such Stockholder
pursuant to this Agreement, (ii) grant any option to purchase, or otherwise
enter into any contract to sell, assign, transfer, pledge or otherwise dispose

or any transaction that transfers, in whole or in part, directly or indirectly,
the economic consequence of ownership of the AmPaM Stock or AmPaM Notes,
whether any such swap or transaction is to be settled by delivery of shares of
AmPaM Stock or AmPaM Notes or other securities, by the delivery or payment of
cash or otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A)
as otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock,
pursuant to Section 17 hereof, (C) for transfers to (I) immediate family
members of such Stockholder who agree with AmPaM in writing to be bound by the
restrictions set forth in this Section 15.1, (II) trusts, limited partnerships
or other estate planning entities for the benefit of such Stockholder or family
members of such Stockholder which have agreed with AmPaM in writing, through
action taken by the trustees, partners or other persons having authority to
bind the trust, limited partnership or other estate planning entity, to be
bound by the restrictions set forth in this Section 15.1, (III) any charitable

Stock or AmPaM Notes to AmPaM pursuant to Section 11.5(d), (E) for transfers to
another Stockholder, to another person or entity who receives shares of AmPaM
Stock or AmPaM Notes or AmPaM Series A Preferred Stock pursuant to the Other
Agreements or to Sterling City Capital LLC or any of its Affiliates provided
that (1) such transaction is exempt from the registration requirements of the
1933 Act as evidenced by the delivery to AmPaM of an opinion of counsel in form
and substance reasonably satisfactory to AmPaM and (2) any such transferee
agrees in writing to be bound by the restrictions set forth in this Section
15.1, (F) transfers of shares of AmPaM Notes, shares of AmPaM Stock, or grants
of options to purchase shares of AmPaM Stock, by such Stockholder to employees
of the Company of up to an aggregate of 15% of the shares of AmPaM Stock
received by such Stockholder pursuant to this Agreement provided that (1) any
such transaction is exempt from the registration requirements of the 1933 Act
as evidenced by the delivery to AmPaM of an opinion of counsel in form and
substance reasonably satisfactory to AmPaM and (2) any such employee agrees
with AmPaM in writing to be bound by the restrictions set forth in this Section
15.1 or (G) the sale by such Stockholder in an IPO of shares of AmPaM Stock
representing not more than 10% of the Aggregate Consideration in cash;
provided,


                                       50

<PAGE>   59


however, that in no circumstance will a Stockholder be entitled to sell shares
of AmPaM Stock in an IPO to the extent that the sale of such shares by such
Stockholder would result in such Stockholder receiving in excess of 45% of the
Aggregate Consideration in cash; and, provided further, if AmPaM 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
Section 17.1 that the number of shares to be sold by persons other than AmPaM
is greater than the number of such shares which can be offered without
adversely affecting the success of the offering, AmPaM may reduce pro rata
(among the Stockholders and all other selling security holders in the offering)
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. During the Restricted Period, the certificates evidencing
the AmPaM Stock or AmPaM Notes delivered to the Stockholders pursuant to
Section 3 of this Agreement will bear a legend substantially in the form set
forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION
OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the
shares of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes
to be delivered to such 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 sold, assigned, exchanged, transferred,
pledged or otherwise disposed of without compliance with the 1933 Act which,
among other matters, would require registration under the 1933 Act unless
exemption from the registration requirements is available for such transaction.
The AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to be
acquired by each Stockholder pursuant to this Agreement is being acquired
solely for such Stockholder's own account, for investment purposes only, and
with no present intention of selling, assigning, exchanging, transferring,
pledging, or otherwise disposing of it. Each Stockholder covenants, warrants
and represents that neither the shares of AmPaM Stock, the Additional
Consideration Right nor any AmPaM Notes issued to such Stockholder will be
offered, sold, assigned, exchanged, pledged, 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 certificates
representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision),
and is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of
the nature described in the preceding sentence and all questions have been
answered to such Stockholder's satisfaction. Except as set forth on Schedule
16.2, each Stockholder is an "accredited investor" as defined in Rule 501(a) of
the 1933 Act. Neither the foregoing nor any investigation made by the
Stockholders referred to above shall in any way affect the representations,
warranties, covenants and agreements of AmPaM made herein except to the extent
that AmPaM is relying upon the representations of the Stockholders in Section
16.1 and in this Section 16.2 for purposes of AmPaM's representations and
warranties in Sections 6.9, 6.11, 6.15 and 6.17 hereof as specified therein.



                                       52

<PAGE>   61


         16.3 RELIANCE BY AmPaM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to
register any AmPaM Stock for its own or other's 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 AmPaM and
(ii) registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other
distribution with respect to, or in exchange for, or in replacement of such
AmPaM Stock) which any such Stockholder requests, other than shares of AmPaM
Stock which may then be immediately sold under Rule 144(k) (or any similar or
successor provision) promulgated under the 1933 Act, and other than shares of
AmPaM Stock that have been theretofore sold by the Stockholder in accordance
with the 1933 Act, provided that AmPaM shall have the right to reduce pro rata
the number of shares of each selling Stockholder included in such registration
to the extent that inclusion of such shares would, in the written opinion of
tax counsel to AmPaM or its independent auditors, jeopardize the status of the
transactions contemplated hereby and by the Private Placement Memorandum as a
tax-free organization under Section 351 of the Code; provided, however, that
with respect to a proposal by AmPaM to register AmPaM Stock under the 1933 Act
in connection with an IPO, no Stockholder shall be permitted pursuant to this
Section 17.1 to have included in such registration more shares of AmPaM Stock
than permitted to be sold by such Stockholder pursuant to Section 15.1. In
addition, if AmPaM 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 AmPaM is greater than the number of
such shares which can be offered without adversely affecting the success of the
offering, AmPaM may reduce pro rata (among the Stockholders and all other
selling security holders in the offering) 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. If any
Stockholder disapproves of the terms of the underwriting, that Stockholder may
elect to withdraw therefrom by written notice to AmPaM and the managing
underwriter. That Stockholder's shares of AmPaM Stock so withdrawn shall also
be withdrawn from registration; provided, however, that, if by the withdrawal
of such shares a greater number of shares of AmPaM


                                       53

<PAGE>   62


Stock held by other Stockholders may be included in such registration, then
AmPaM shall offer to all other Stockholders of AmPaM the right to include
additional shares in the same proportion used in effecting the above
limitations. AmPaM shall not, for a period of two years following the Closing
Date, grant to any other person any rights to cause AmPaM to register any
securities in priority over, or in precedent to, the rights granted to the
Stockholders hereunder and to the stockholders of the Other Founding Companies
pursuant to Section 17 of the Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a
         representative of the Stockholders with copies of all such documents
         proposed to be filed) as promptly as practical;

              (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

              (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth
         in such registration statement or supplement to the prospectus;

              (iv) 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;

              (v) Make "generally available to its security holders" (within
         the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;


                                       54

<PAGE>   63


              (vi) Make every reasonable effort to obtain the withdrawal of any
         order suspending the effectiveness of the registration statement at
         the earliest possible moment;

              (vii) If requested by the managing underwriter or underwriters,
         if any, or any participating Stockholder, promptly incorporate in a
         prospectus supplement or post-effective amendment such information as
         the managing underwriter or underwriters or any participating
         Stockholder, as the case may be, reasonably requests to be included
         therein, including, without limitation, information with respect to
         the number of shares of AmPaM Stock being sold by participating
         Stockholders to any underwriter or underwriters, the purchase price
         being paid therefor by such underwriter or underwriters and with
         respect to any other terms of an underwritten offering of the shares
         of AmPaM Stock to be sold in such offering, and promptly make all
         required filings of such prospectus by supplement or post-effective
         amendment;

              (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition
         pursuant to such registration statement, and the counsel retained by
         the participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or
         any such underwriter (collectively, the "Inspectors"), all financial
         and other records, pertinent corporate documents and properties of
         AmPaM (the "Records"), as shall be reasonably necessary to enable them
         to exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

              (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

              (x) 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 required to
         be kept effective, provided that AmPaM shall not be required to become
         subject to taxation, to qualify generally to do business or to file a
         general consent to service of process in any such states or
         jurisdictions;

              (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any securities exchanges or
         trading systems on which similar securities issued by AmPaM are then
         listed or included; and


                                       56

<PAGE>   64


              (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in
         effect), together with any associated term sheet, contains an untrue
         statement of a material fact or omits to state any fact required to be
         stated therein or necessary to make the statements therein (in the
         case of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading, and, at the
         request of such Stockholder, AmPaM promptly 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
         required to be stated therein or necessary to make the statements
         therein (in the case of the prospectus or any preliminary prospectus,
         in light of the circumstances under which they were made) not
         misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall
be borne by AmPaM.

         17.3     INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue
statement of material fact contained or incorporated by reference in any
registration statement, prospectus or preliminary prospectus or associated term
sheet or any omission or alleged omission to state or incorporated by reference
therein a material fact required to be stated or incorporated by reference
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 AmPaM 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 AmPaM has furnished such Indemnified Party with a sufficient number of
copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning
of the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged


                                       56

<PAGE>   65


untrue statement of a material fact or any omission or alleged omission to
state therein a material fact required to be stated in the registration
statement or prospectus or any amendment thereof or supplement thereto or
necessary to make the statements therein not misleading, but only to the extent
that such untrue or alleged untrue statement or omission or alleged omission is
contained in or omitted from information so furnished in writing to AmPaM by
such Stockholder expressly for use in 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 hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i)
each participating Stockholder shall execute and deliver to AmPaM a written
power of attorney instrument that (A) appoints an officer of AmPaM as such
Stockholder's attorney-in-fact for purposes of executing and delivering an
underwriting agreement among AmPaM, the underwriters named therein and such
Stockholder specifying the terms and conditions applicable to the sale of AmPaM
Stock of such Stockholder in such offering and (B) otherwise is in such form
and containing such provisions as are customary in the securities business for
such an arrangement in connection with an underwritten registered offering in
which one or more stockholders of the issuer are participants, including a
provision that authorizes the attorney-in-fact appointed by such Stockholder to
execute and deliver such an underwriting agreement in the event that the net
price per share to be received by such Stockholder from the sale of the shares
of AmPaM Stock to be sold in such offering is not less than a price specified
in such instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters


                                       57

<PAGE>   66


specifically for inclusion in any such registration statement and (B) such
Stockholder shall not be obligated to enter into such an underwriting agreement
in the event that the net price per share to be received by such Stockholder
from the sale of shares of AmPaM Stock to be sold in such offering is less than
the floor price specified in the power of attorney instrument executed and
delivered to AmPaM pursuant to clause (i) above.

         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares
of AmPaM Stock under this Agreement may be assigned to a transferee or assignee
of any Stockholder to the extent that such transferee or assignee is a member
of the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

              (i) make and keep public information regarding AmPaM available as
         those terms are understood and defined in Rule 144 under the 1933 Act
         beginning 90 days following the effective date of a registration
         statement relating to an IPO;

              (ii) file with the SEC in a timely manner all reports and other
         documents required of AmPaM 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 AmPaM Stock,
         furnish to each Stockholder forthwith upon written request a written
         statement by AmPaM as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 AmPaM, 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.      REDEMPTION OF AmPaM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal
payments, if any, made with respect to AmPaM Notes held by such Stockholder)
equal to or exceeding 50% of the Aggregate Consideration on or prior to the
third anniversary of the Closing Date, such Stockholder shall have the right
(the "Put Right"), but not the


                                       58

<PAGE>   67


obligation, commencing on the third anniversary of the Closing Date to require
AmPaM to purchase a number of shares of AmPaM Stock then owned by such
Stockholder, subject to the limitations set forth in Section 18.2 below. The
purchase price for such redemption shall be $13.00 per share, such price to be
subject to appropriate adjustment to reflect any reclassification, stock
dividend, subdivision, split-up or combination of shares of AmPaM Stock after
the date hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified,
AmPaM shall be obligated to purchase from each eligible Stockholder no less
than 10% of the AmPaM Stock held by such Stockholder annually; provided,
however, that the Stockholders shall not be entitled to exercise their Put
Rights if and to the extent the Company has not achieved the Target Net Income
(as defined in Annex I hereto) for the year preceding the year in which a
Stockholder seeks to exercise his Put Right. The redemptions will be funded by
internal cash flows or alternative financing arrangements but AmPaM's
obligation to make any redemption pursuant to this Section 18 will be subject
to the covenants and restrictions contained in AmPaM's then existing private or
public debt or equity instruments.

         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right
by giving written notice (the "Put Notice") to AmPaM within thirty (30) days of
the third anniversary of the execution hereof. If any Stockholder does not
provide AmPaM with a Put Notice within such thirty-day period, the Put Right
applicable to such Stockholder shall expire. The date for closing the sale of
any shares of AmPaM Stock pursuant to a proper exercise of a Put Right shall in
no event be earlier than 90 days after the date AmPaM receives the Put Notice.
Any such closing shall be at such time of day and place as shall be mutually
agreed between such holder and AmPaM. At such closing AmPaM shall make payment
for the AmPaM Stock to be repurchased by wire transfer of immediately available
funds to a bank account designated by such Stockholder for such purpose and
such Stockholder shall deliver to AmPaM certificates, duly endorsed for
transfer, representing the shares of AmPaM Stock to be purchased and sold
pursuant to the exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger
or consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any,


                                       59

<PAGE>   68



which are then held by persons other than the holders of AmPaM Common Stock as
of the Closing Date constitute 50% or more of AmPaM Common Stock outstanding as
of the date of the consummation of such transaction.

19.      GENERAL

         19.1 COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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 AmPaM on and after the Closing 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 Closing Date.

         19.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law and except as
provided in Section 17.5) and shall be binding upon and shall inure to the
benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

         19.3 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 and AmPaM 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 by
a written instrument executed by the Stockholders, the Company and AmPaM,
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.

         19.4 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. A
telecopied facsimile of an executed counterpart of this Agreement shall be
sufficient to evidence the binding agreement of each party to the terms hereof.
However, each party agrees to return to the other parties an original, duly
executed counterpart of this Agreement promptly after delivery of a telecopied
facsimile thereof.

         19.5 BROKERS AND AGENT. Except as disclosed on Schedule 18.5, each
party hereto represents and warrants that it employed no broker or agent in

AmPaM funds to pay any such fees, expenses and disbursements, provided that
such reimbursement and loan repayment obligation shall be limited to the
foregoing fees, expenses, and disbursements which are out-of-pocket expenses of
AmPaM, Sterling City Capital, LLC or any person or entity which is an Affiliate
thereof. Sterling City Capital, LLC shall be reimbursed by AmPaM in the form of
AmPaM Notes. AmPaM retains the right, within a reasonable period following the

Capital, LLC is reimbursed. Each Stockholder shall pay all sales, use,
transfer, real property transfer, recording, gains, stock transfer and other

all Taxes due by him upon receipt of the consideration payable pursuant to
Section 1 hereof. The Stockholders acknowledge that the risks of the
transactions contemplated hereby include Tax risks, with respect to which the
Stockholders are relying substantially on the opinion contemplated by Section

         19.10 EXERCISE OF RIGHTS AND REMEDIES. Except as otherwise provided
herein, no delay of or omission in the exercise of any right, power or remedy
accruing to any party as a result of any breach or default by any other party
under this Agreement shall impair any such right, power or remedy, nor shall it
be construed as a waiver of or acquiescence in any such breach or default, or
of any similar breach or default occurring later; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
occurring before or after that waiver.

         19.11 TIME. Time is of the essence with respect to this Agreement.

         19.12 REFORMATION AND SEVERABILITY. In case any provision of this
Agreement shall be invalid, illegal or unenforceable, it shall, to the extent
possible, be modified in such manner as to be valid, legal and enforceable but
so as to most nearly retain the intent of the parties, and if such modification
is not possible, such provision shall be severed from this Agreement, and in
either case the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby. No provision of this Agreement shall be interpreted or construed
against any party solely because that party or its legal representative drafted
such provision.

         19.13 REMEDIES CUMULATIVE. No right, remedy or election given by any

receive a majority of the Aggregate Consideration specified in Section I of
Annex I to this Agreement if the transactions contemplated hereby were
consummated. Any amendment or waiver effected in accordance with this Section
19.15 shall be binding upon each of the parties hereto, any other person
receiving AmPaM Stock in connection with the purchase and sale of the Company
Stock and each future holder of such AmPaM Stock. Any consent of the
Stockholders who would receive a majority of the shares of the Aggregate
Consideration pursuant to Section I of Annex I of this Agreement if the
transactions contemplated hereby were consummated shall be deemed to be the
consent of the Stockholders for purposes of provisions of this Agreement as to
which a consent of the Stockholders may be requested or required.

         19.16 MEDIATION AND ARBITRATION. If a dispute arises out of or relates
to this Agreement, or the breach thereof, and if said dispute cannot be settled
through direct discussions, the parties agree to first endeavor to settle the
dispute in an amicable manner by mediation administered by the American
Arbitration Association under its then prevailing Commercial Mediation Rules,
before resorting to arbitration. Thereafter, any unresolved controversy or
claim arising out of or relating


                                       63

<PAGE>   72


to this Agreement, or the breach thereof, shall be settled by arbitration
administered by the American Arbitration Association in accordance with its
then prevailing Commercial Arbitration Rules. The enforcement, interpretation
and procedural and substantive effect of the obligation to arbitrate created by
this Section 19.16 shall be governed by the Federal Arbitration Act as amended
from time to time, 9 U.S.C. Section 1 et seq. The parties hereby disclaim any
intention to have the substantive or procedural law of any state or other
jurisdiction, other than the law of the United States as embodied in the
Federal Arbitration Act, applied to such obligation. Any such mediation or
arbitration proceeding will be conducted in Houston, Texas.

<PAGE>   47


Stockholders' personal liability shall be released. AmPaM will indemnify the
Stockholders against any loss or damage suffered as a result of the personal
guarantees.

         10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as
contemplated by this Agreement, after the Closing Date, AmPaM shall not and

jeopardize the tax-free status of the exchange of Company Stock for AmPaM Stock

                  (a) the retirement or reacquisition, directly or indirectly,
of all or part of the AmPaM Stock issued in connection with the transactions
contemplated hereby; or

                  (b) the entering into of financial arrangements for the
benefit of the Stockholders other than as described in the Private Placement
Memorandum or as described in this Agreement.

         10.3 PREPARATION AND FILING OF TAX RETURNS; PAYMENT OF TAXES.

                  (a) The Company, if possible, or otherwise the Stockholders
shall file or cause to be filed all income Tax Returns (federal, state, local
or otherwise) of any Acquired Party for all taxable periods that end on or
before the Closing Date, and shall permit AmPaM to review all such Tax Returns
prior to such filings. Unless the Company is a C corporation, the Stockholders
shall pay or cause to be paid all income Tax liabilities (in excess of all
amounts already paid with respect thereto or properly accrued or reserved with
respect thereto on the Financial Statements) with respect to the Company's
operations for all periods through and including the Closing Date.

                  (b) AmPaM shall file or cause to be filed all separate
Returns of, or that include, any Acquired Party for all taxable periods ending
after the Closing Date.

                  (c) Unless required by applicable law, regulations or
government proceedings, AmPaM shall not take any action, including any
amendment of a Tax Return of any Acquired Party, if such action would result in
additional Tax liabilities payable by any of the Stockholders for periods
ending on or prior to the Closing Date.

                  (d) Each party hereto shall, and shall cause its subsidiaries
and Affiliates to, provide to each of the other parties hereto such cooperation
and information as any of them reasonably may request in 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 audit or other proceeding in
respect of Taxes. Such cooperation and information shall include providing
copies 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

sentence, each party required to file Returns pursuant to this Agreement shall
bear all costs of filing such Returns.

                  (e) Each of the Company, AmPaM and each Stockholder shall
comply with the tax reporting requirements of Section 1.351-3 of the 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.

         10.4 DIRECTORS. The persons named in the Private Placement Memorandum
shall be appointed as directors and elected as officers of AmPaM, as and to the
extent set forth in the Private Placement Memorandum, promptly following the
Closing Date; provided, however, that the parties hereto acknowledge that if
the Company consummates an IPO, the persons who will serve as directors and
executive officers of AmPaM will be adjusted as appropriate for a publicly
traded entity, with any such changes being subject to the approval of the
majority of the Board of Directors of AmPaM.

         10.5 LEGAL OPINIONS. If required by the lenders pursuant to the terms
of any agreements related to financing of the cash amounts referred to in
Section 9.11 hereof, the Company shall cause its counsel to deliver to such
lenders, at the Closing, an opinion of counsel in substantially the form
attached hereto as Annex V.

11.      INDEMNIFICATION

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

         11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS.

         (a) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement until the applicable Expiration Date (as defined in
the introductory paragraph to Section 5(A)), provided that for purposes of
clause (iii) below, the applicable 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 AmPaM as a result of
or arising from (i) any breach of the representations and warranties of the
Company set forth herein or on the schedules attached hereto or certificates
delivered pursuant to this Agreement, (ii) any breach of any covenant or
agreement on the part of the Company under this Agreement, or (iii) any
liability under the 1933 Act or any Federal or state securities 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 solely to the
Company which was based upon information provided to AmPaM or its counsel in
writing by the Company specifically for inclusion in the Private Placement
Memorandum and is contained in the Private Placement Memorandum, or any
amendment thereof

                                       40

<PAGE>   49


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 required to
be stated therein or necessary to make the statements therein not misleading;
provided, however, that (i) no Stockholder shall be liable for any
indemnification obligation pursuant to this Section 11.1 in excess of such
Stockholder's pro rata share thereof determined by reference to the aggregate
value of the Base Cash Amount (as defined in Annex I of this Agreement), the
principal amount of AmPaM Notes and the shares of AmPaM Stock (valued at a
price of $13.00 per share) received by such Stockholder pursuant to Section
I.A. of Annex I hereto (without giving effect to the adjustments provided in
Sections I.B. and I.C. thereof) (giving effect to the value of such AmPaM Stock
and without giving effect to such adjustments, collectively, the "Aggregate
Consideration") such Stockholder would receive pursuant to Section I of Annex I
of this Agreement if the transactions contemplated hereby were consummated in
relation to the Aggregate Consideration all Stockholders would receive pursuant
to Section I of Annex I of this Agreement if the transactions contemplated
hereby were consummated and (ii) the indemnity obligations in this Section
11.1(a) shall not be applicable to any Stockholder who has sold all of his
shares of Company Stock to the other Stockholder prior to the Closing Date.

         (b) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement, 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 AmPaM as a result of or arising from (i)
any breach of the representations and warranties of such Stockholder set forth
in Section 5(B) hereof, (ii) any breach of any covenant or agreement on the
part of such Stockholder under this Agreement, or (iii) any liability under the
1933 Act or any Federal or state securities 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 solely to such Stockholder which was
based upon information provided to AmPaM or its counsel in writing by such
Stockholder specifically for inclusion in the Private Placement Memorandum and
is contained in the Private Placement Memorandum, 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 solely to such Stockholder
required to be stated therein or necessary to make the statements therein in
light of the circumstances in which such statements were made not misleading;
provided, however, that such indemnity shall not be applicable to any
Stockholder who has sold all of his shares of Company Stock to the other
Stockholder prior to the Closing Date.

         (c) AmPaM acknowledges and agrees that other than the representations
and warranties of the Company or the Stockholders specifically contained in
this Agreement, there are no representations or warranties of the Company or
the Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

         11.2 INDEMNIFICATION BY AmPaM. AmPaM covenants and agrees that it will
indemnify, defend, protect and hold harmless the Company and the Stockholders
at all times from and after the date of this Agreement until the applicable
Expiration Date (as defined in the introductory paragraph of Section 6,
provided that for purposes of clause (iii) below, the applicable 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 the Company or the Stockholders as a result of or arising from (i)
any breach by AmPaM of its representations and warranties set forth herein or
on the schedules attached hereto or certificates delivered pursuant to this
Agreement, (ii) any breach of any agreement on the part of AmPaM under this
Agreement; or (iii) any liability under the 1933 Act or any Federal or state
securities 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
contained in the Private Placement Memorandum, 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 required to be stated therein or
necessary to make the statements therein not misleading, except to the extent
such is based upon an untrue statement or alleged untrue statement, or omission
or alleged omission, made therein in reliance upon, and in conformity with, the
representations and warranties of the Company or the Stockholders specifically
contained in this Agreement or other information furnished to AmPaM by the
Company or the Stockholders in writing specifically for inclusion therein.

         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim
by a person not a party to this Agreement ("Third Person"), or the commencement
of any action or proceeding by a Third Person, 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 reasonably
satisfactory to the Indemnified Party, 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 or
a conflict of interest is reasonably likely to arise that prevents counsel for
the Indemnifying Party from representing such 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

                                      42

<PAGE>   51


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, 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. 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 pay the Indemnified Party for the settlement amount
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.
With respect to any account, note or other receivable as to which the
Stockholders have paid in full any indemnification obligation pursuant to this
Section 11 as a result of a breach of the representation and warranty made
pursuant to Section 5.11 or as to which a claim in respect thereof has been
asserted pursuant to this Section 11 that has been applied against the
Indemnification Threshold with respect to the Stockholders as a result of a
breach of the representation and warranty made pursuant to Section 5.11, AmPaM
shall cause the Company to assign such account, note or other receivable to the
Stockholders. 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. 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 to this Agreement with respect to
any provision of this Agreement, provided that, nothing herein shall be
construed to limit the right of a party, in a proper case, to seek injunctive
relief for a breach of this Agreement. AmPaM hereby waives, to the fullest
extent permitted under applicable law, any and all other rights, claims and
causes of action, known or unknown, it or any indemnified person may have
against the Company or any Stockholder relating to this Agreement or the
transactions pursuant to this Agreement arising under or based upon any
Federal, state, local or foreign statute, law, rule, regulation or otherwise.
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

                                       43

<PAGE>   52


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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2 (calculated as provided in this Section 11.5) plus (iii) the
principal amount of the AmPaM Notes delivered to the Stockholders pursuant to
Section 1.2, or (b) $50,000 (the "Indemnification Threshold"). Stockholders
shall not assert any claim for indemnification hereunder against AmPaM until
such time as, and solely to the extent that, the aggregate of all claims which
Stockholders may have against AmPaM shall exceed $50,000; provided, however,
that this sentence shall not be applicable with respect of any failure by AmPaM
to (i) deliver the consideration specified in Annex I hereto on the Closing
Date upon the satisfaction, or waiver by AmPaM, of all conditions to the
occurrence of the Closing Date specified in Section 9 or (ii) comply with its
obligations pursuant to Section 10.1. After the $50,000 threshold for AmPaM
(subject to the proviso in the preceding sentence) or the Indemnification
Threshold for a Stockholder has been met, all claims must be made in $10,000
increments, which claims may be cumulated in order to meet such $10,000
thresholds. For purposes of this paragraph, the AmPaM Stock delivered to the
Stockholders shall be valued at $13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is
directly or indirectly related to a breach by such person of any
representation, warranty, covenant or other agreement set forth in this
Agreement. No claim for indemnification against the Stockholders shall limit,
diminish or change any obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at
$13.00 per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of
AmPaM Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration paid to such Stockholder by AmPaM to such Stockholder pursuant to
Annex I. For the purpose of crediting Stockholders for payments made to AmPaM
by means of delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued
at $13.00 per share.

                                       44

<PAGE>   53


         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary
of AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM shall use commercially reasonable
efforts to pursue any available insurance coverage or other rights of indemnity
or reimbursement from third parties with respect to any such loss, liability or
expense.

         12.1 TERMINATION. This Agreement may be terminated at any time prior

         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions

         or the Stockholders prior to or on the Closing Date;

                  (iii) by AmPaM, if the transactions contemplated by this

         to or on the Closing Date;

                  (iv) by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely

         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v) by AmPaM, if a material breach or default shall be made

<PAGE>   54


                  (vii) by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2 PROCEDURE AND EFFECT OF TERMINATION. A determination to terminate
this Agreement by AmPaM pursuant to Section 12.1 shall be valid and effective

termination, AmPaM shall deliver written notice of such termination to the
Other Founding Companies. If this Agreement is terminated as provided in this
Section 12, no party hereto shall have any liability or further obligation
hereunder to any other party, except as provided in Section 14 and Section
18.6, provided, that, 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 that occurred prior to
such termination.

13.      NONCOMPETITION

         13.1 PROHIBITED ACTIVITIES. Robert C. Richey will not, without the

                  (ii) call upon any person who is, at the Closing Date, within
         the Territory, an employee of AmPaM or any subsidiary thereof for the

         of any of the Other Founding Companies for the purpose of soliciting
         customers, orders or contracts for any Plumbing and Mechanical
         Business in direct competition with AmPaM within the Territory;

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

                  (v) disclose to any person, firm, partnership, corporation or
         business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or
         any of its subsidiaries within the two (2) years prior to the Closing
         Date for any reason or purpose whatsoever except to the extent that
         the Company has in the past disclosed such information to the public
         for valid business reasons; or

                  (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

         13.2 PROHIBITED ACTIVITIES (BAKER). Thomas L. Baker ("Baker") will

         Plumbing and Mechanical Business in the state of Nevada;

                  (ii) bid on or enter into an agreement to perform any work

                  (iii) bid or enter into an agreement to perform any work
         which would constitute Plumbing and Mechanical Business involving a
         continuing phase of any phased project for which the Company has
         contracted, regardless of the builder, unless Baker is advised in
         writing by the builder of such project that such builder does not
         intend to employ or contract with the Company for such continuing
         phase or phases;

                  (iv) call upon any person who is, at the Closing Date, an

         of twenty-nine (29) R.C.R. Employees at any time during the second
         twelve months of the Baker Restricted Period. The term "R.C.R.
         Employees" shall mean any person who is an active employee of the
         Company as of February 28, 1999, but shall not include any person who
         is laid off or whose employment is terminated, by the Company, or any
         of Baker's children.

                  (vi) conduct a business having gross sales from the Plumbing

                  (vii) except as required by process of law, disclose, reveal
         or furnish to any other person, entity or government agency, any

         whether prepared by him or otherwise coming into his possession. The
         term "Trade Secret" shall have the meaning provided in the Uniform
         Trade Secrets Act, Section 3426.1(d) of the California Civil Code.

                  The Company will not, without the prior written consent of
Baker, for the Baker Restricted Period, for any reason whatsoever, directly or
indirectly, for itself or on behalf of or in conjunction with any other person,
persons, company, partnership, corporation or business of whatever nature, bid
or enter into an agreement to perform any work which would constitute Plumbing
and Mechanical Business involving a continuing phase of any project for which
Baker has contracted, regardless of the builder, unless the Company is advised
in writing by the builder of such project that such builder does not intend to
employ or contract with Baker for such continuing phase or phases.

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

         13.4 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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         13.5 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.

         13.6 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 AmPaM or any subsidiary thereof, whether predicated on this Agreement
or otherwise, shall not constitute a defense to the enforcement by AmPaM of
such covenants. It is specifically agreed that the period of two (2) 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 found to be in violation of any provision of this Section 13 as
determined by any of (i) a written agreement to such effect executed and
delivered by AmPaM and such Stockholder, (ii) a determination by an arbitration
panel pursuant to an arbitration conducted pursuant to Section 18.16 hereof or
(iii) a non-appealable judgment of a court of competent jurisdiction. The
covenants contained in Section 13 shall not be affected by any breach of any
other provision hereof by any party hereto. The covenants contained in Section
13 shall have no effect if the transactions contemplated by this Agreement are
not consummated.

         13.7 MATERIALITY. The Company and the Stockholders hereby agree that
the covenants contained in this Section 13 are a material and substantial part
of this transaction.

14.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION

         14.1 STOCKHOLDERS. Robert C. Richey recognizes and acknowledges that
he had 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 AmPaM, such as operational policies, customer lists, and
pricing and cost policies that are valuable, special and unique assets of the
Company's, the Other Founding Companies' and/or AmPaM's respective businesses.
Robert C. Richey 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 AmPaM, (b)
following the Closing, such information may be disclosed by Robert C. Richey as
is required in the course of performing his duties for AmPaM or the Company and
(c) to its counsel and other advisers, provided that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 14.1;
provided, however that (i) the foregoing disclosure prohibition shall not apply
in the event that (i) such information becomes known to the public generally
through no fault of Robert C. Richey, (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), Robert C. Richey
shall, if possible, give prior written notice thereof to AmPaM and provide
AmPaM 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 Robert C. Richey of the provisions of this Section,
AmPaM shall be entitled to an injunction restraining Robert C. Richey from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting AmPaM 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, Robert C. Richey shall have none of the above-mentioned
restrictions on their ability to disseminate confidential information with
respect to the Company.

         14.2 AmPaM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies
that are valuable, special and unique assets of the Company's business. AmPaM
agrees that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes
known to the public generally through no fault of AmPaM, (B) disclosure is
required by law or the order of any

                                       50

<PAGE>   59


governmental authority under color of law, provided, that prior to disclosing
any information pursuant to this clause (B), AmPaM 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 (C) 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 AmPaM of the
provisions of this Section 14.2, the Company and the Stockholders shall be
entitled to an injunction restraining AmPaM 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.
In the event the transactions contemplated by this Agreement are not
consummated for any reason, AmPaM shall nevertheless remain subject to this
Section 14.2, except that it shall not be permitted to make any disclosures
otherwise than pursuant to clause (A), (B) or (C) above.

         14.3 DAMAGES. Because of the difficulty of measuring economic losses
as a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the
covenant may be enforced against the other parties by injunctions and
restraining orders.

         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 Closing Date.

         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AmPaM STOCK AND AmPaM NOTES.

cash or otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A)
as otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock,

that (1) such transaction is exempt from the registration requirements of the
1933 Act as evidenced by the delivery to AmPaM of an opinion of counsel in form
and substance reasonably satisfactory to AmPaM and (2) any such transferee
agrees in writing to be bound by the restrictions set forth in this Section
15.1, (F) transfers of shares of AmPaM Notes, shares of AmPaM Stock, or grants
of options to purchase shares of AmPaM Stock, by such Stockholder to employees
of the Company of up to an aggregate of 15% of the shares of AmPaM Stock

such transaction is exempt from the registration requirements of the 1933 Act
as evidenced by the delivery to AmPaM of an opinion of counsel in form and
substance reasonably satisfactory to AmPaM and (2) any such employee agrees
with AmPaM in writing to be bound by the restrictions set forth in this Section
15.1 or (G) the sale by such Stockholder in an IPO of shares of AmPaM Stock
representing not more than 10% of the Aggregate Consideration in cash;
provided, however, that in no circumstance will a Stockholder be entitled to
sell shares of AmPaM Stock in an IPO to the extent that the sale of such shares
by such Stockholder would result in such Stockholder receiving in excess of 45%
of the Aggregate Consideration in cash; and, provided further, if AmPaM 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 Section 17.1 that the number of shares to be sold by persons other than
AmPaM is greater than the number of such shares which can be offered without
adversely affecting the success of the offering, AmPaM may reduce pro rata
(among the Stockholders and all other selling security holders in the offering)
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. During the Restricted Period, the certificates evidencing
the AmPaM Stock or AmPaM Notes delivered to the Stockholders pursuant to
Section 3 of this Agreement will bear a legend substantially in the form set
forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION

                                       52

OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other

indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the
shares of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes
to be delivered to such 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 sold, assigned, exchanged, transferred,
pledged or otherwise disposed of without compliance with the 1933 Act which,
among other matters, would require registration under the 1933 Act unless
exemption from the registration requirements is available for such transaction.
The AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to be
acquired by each Stockholder pursuant to this Agreement is being acquired
solely for such Stockholder's own account, for investment purposes only, and
with no present intention of selling, assigning, exchanging, transferring,
pledging, or otherwise disposing of it. Each Stockholder covenants, warrants
and represents that neither the shares of AmPaM Stock, the Additional
Consideration Right nor any AmPaM Notes issued to such Stockholder will be
offered, sold, assigned, exchanged, pledged, 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 certificates
representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

                                       53

<PAGE>   62


         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision),
and is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of
the nature described in the preceding sentence and all questions have been
answered to such Stockholder's satisfaction. Except as set forth on Schedule
16.2, each Stockholder is an "accredited investor" as defined in Rule 501(a) of
the 1933 Act. Neither the foregoing nor any investigation made by the
Stockholders referred to above shall in any way affect the representations,
warranties, covenants and agreements of AmPaM made herein except to the extent
that AmPaM is relying upon the representations of the Stockholders in Section
16.1 and in this Section 16.2 for purposes of AmPaM's representations and
warranties in Sections 6.9, 6.11, 6.15 and 6.17 hereof as specified therein.

         16.3 RELIANCE BY AMPAM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to register
any AmPaM Stock for its own or other's 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 AmPaM and (ii)
registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other
distribution with respect to, or in exchange for, or in replacement of such
AmPaM Stock) which any such Stockholder requests, other than shares of AmPaM
Stock which may then be immediately sold under Rule 144(k) (or any similar or
successor provision) promulgated under the 1933 Act, and other than shares of
AmPaM Stock that have been theretofore sold by the Stockholder in accordance
with the 1933 Act, provided that AmPaM shall have the right to reduce pro rata
the

                                       54

<PAGE>   63


number of shares of each selling Stockholder included in such registration to
the extent that inclusion of such shares would, in the written opinion of tax
counsel to AmPaM or its independent auditors, jeopardize the status of the
transactions contemplated hereby and by the Private Placement Memorandum as a
tax-free organization under Section 351 of the Code; provided, however, that
with respect to a proposal by AmPaM to register AmPaM Stock under the 1933 Act
in connection with an IPO, no Stockholder shall be permitted pursuant to this
Section 17.1 to have included in such registration more shares of AmPaM Stock
than permitted to be sold by such Stockholder pursuant to Section 15.1. In
addition, if AmPaM 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 AmPaM is greater than the number of
such shares which can be offered without adversely affecting the success of the
offering, AmPaM may reduce pro rata (among the Stockholders and all other
selling security holders in the offering) 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. If any
Stockholder disapproves of the terms of the underwriting, that Stockholder may
elect to withdraw therefrom by written notice to AmPaM and the managing
underwriter. That Stockholder's shares of AmPaM Stock so withdrawn shall also
be withdrawn from registration; provided, however, that, if by the withdrawal
of such shares a greater number of shares of AmPaM Stock held by other
Stockholders may be included in such registration, then AmPaM shall offer to
all other Stockholders of AmPaM the right to include additional shares in the
same proportion used in effecting the above limitations. AmPaM shall not, for a
period of two years following the Closing Date, grant to any other person any
rights to cause AmPaM to register any securities in priority over, or in
precedent to, the rights granted to the Stockholders hereunder and to the
stockholders of the Other Founding Companies pursuant to Section 17 of the
Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a
         representative of the Stockholders with copies of all such documents
         proposed to be filed) as promptly as practical;

                  (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the

                                       55

<PAGE>   64


         provisions of the 1933 Act applicable to it with respect to the
         disposition of all securities covered by such registration statement
         during the applicable period in accordance with the intended methods
         of disposition by the sellers thereof set forth in such registration
         statement or supplement to the prospectus;

                  (iv) 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;

                  (v) Make "generally available to its security holders"
         (within the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;

                  (vi) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of the registration statement
         at the earliest possible moment;

                  (vii) If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment
         such information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM Stock being sold by
         participating Stockholders to any underwriter or underwriters, the
         purchase price being paid therefor by such underwriter or underwriters
         and with respect to any other terms of an underwritten offering of the
         shares of AmPaM Stock to be sold in such offering, and promptly make
         all required filings of such prospectus by supplement or
         post-effective amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition
         pursuant to such registration statement, and the counsel retained by
         the participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or
         any such underwriter (collectively, the "Inspectors"), all financial
         and other records, pertinent corporate documents and properties of
         AmPaM (the "Records"), as shall be reasonably necessary to enable them
         to exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or

                                       56

<PAGE>   65


         (ii) the release of such Records is ordered pursuant to a subpoena or
         other order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x) 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 required to be kept effective, provided that
         AmPaM shall not be required to become subject to taxation, to qualify
         generally to do business or to file a general consent to service of
         process in any such states or jurisdictions;

                  (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any securities exchanges or
         trading systems on which similar securities issued by AmPaM are then
         listed or included; and

                  (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in
         effect), together with any associated term sheet, contains an untrue
         statement of a material fact or omits to state any fact required to be
         stated therein or necessary to make the statements therein (in the
         case of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading, and, at the
         request of such Stockholder, AmPaM promptly 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
         required to be stated therein or necessary to make the statements
         therein (in the case of the prospectus or any preliminary prospectus,
         in light of the circumstances under which they were made) not
         misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall
be borne by AmPaM.

         17.3 INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue
statement of material fact contained or incorporated by reference in any
registration statement, prospectus or preliminary prospectus or associated term
sheet or any omission or alleged omission to state or incorporated by reference
therein a material fact required to be stated or incorporated by reference
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 AmPaM 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 AmPaM has furnished such Indemnified Party with a sufficient number of
copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning
of the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged untrue statement of a material fact or any
omission or alleged omission to state therein a material fact required to be
stated in the registration statement or prospectus or any amendment thereof or
supplement thereto or necessary to make the statements therein not misleading,
but only to the extent that such untrue or alleged untrue statement or omission
or alleged omission is contained in or omitted from information so furnished in
writing to AmPaM by such Stockholder expressly for use in 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 hereunder 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 that 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

                                       58

<PAGE>   67


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 Sections 17.1 covering an underwritten registered offering, (i)
each participating Stockholder shall execute and deliver to AmPaM a written
power of attorney instrument that (A) appoints an officer of AmPaM as such
Stockholder's attorney-in-fact for purposes of executing and delivering an
underwriting agreement among AmPaM, the underwriters named therein and such
Stockholder specifying the terms and conditions applicable to the sale of AmPaM
Stock of such Stockholder in such offering and (B) otherwise is in such form
and containing such provisions as are customary in the securities business for
such an arrangement in connection with an underwritten registered offering in
which one or more stockholders of the issuer are participants, including a
provision that authorizes the attorney-in-fact appointed by such Stockholder to
execute and deliver such an underwriting agreement in the event that the net
price per share to be received by such Stockholder from the sale of the shares
of AmPaM Stock to be sold in such offering is not less than a price specified
in such instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters specifically for inclusion in any such registration statement and
(B) such Stockholder shall not be obligated to enter into such an underwriting
agreement in the event that the net price per share to be received by such
Stockholder from the sale of shares of AmPaM Stock to be sold in such offering
is less than the floor price specified in the power of attorney instrument
executed and delivered to AmPaM pursuant to clause (i) above.

         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares
of AmPaM Stock under this Agreement may be assigned to a transferee or assignee
of any Stockholder to the extent that such transferee or assignee is a member
of the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

                  (i) make and keep public information regarding AmPaM
         available as those terms are understood and defined in Rule 144 under
         the 1933 Act beginning 90 days following the effective date of a
         registration statement relating to an IPO;

                                       59

<PAGE>   68


                  (ii) file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current
         public information requirements of Rule 144 (at any time from and
         after 90 days following the effective date of a registration statement
         relating to an IPO), 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 AmPaM, 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.      REDEMPTION OF AMPAM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal
payments, if any, made with respect to AmPaM Notes held by such Stockholder)
equal to or exceeding 50% of the Aggregate Consideration on or prior to the
third anniversary of the Closing Date, such Stockholder shall have the right
(the "Put Right"), but not the obligation, commencing on the third anniversary
date of the Closing Date to require AmPaM to purchase a number of shares of
AmPaM Stock then owned by such Stockholder, subject to the limitations set
forth in Section 18.2 below. The purchase price for such redemption shall be
$13.00 per share, such price to be subject to appropriate adjustment to reflect
any reclassification, stock dividend, subdivision, split-up or combination of
shares of AmPaM Stock after the date hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified,
AmPaM shall be obligated to purchase from each eligible Stockholder no less
than 10% of the AmPaM Stock held by such Stockholder annually; provided,
however, that the Stockholders shall not be entitled to exercise their Put
Rights if and to the extent the Company has not achieved the Target Net Income
(as defined in Annex I hereto) for the year preceding the year in which a
Stockholder seeks to exercise his Put Right. The redemptions will be funded by
internal cash flows or alternative financing arrangements but AmPaM's
obligation to make any redemption pursuant to this Section 18 will be subject
to the covenants and restrictions contained in AmPaM's then existing private or
public debt or equity instruments.

                                       60

<PAGE>   69


         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right
by giving written notice (the "Put Notice") to AmPaM within thirty (30) days of
the third anniversary of the execution hereof. If any Stockholder does not
provide AmPaM with a Put Notice within such thirty-day period, the Put Right
applicable to such Stockholder shall expire. The date for closing the sale of
any shares of AmPaM Stock pursuant to a proper exercise of a Put Right shall in
no event be earlier than 90 days after the date AmPaM receives the Put Notice.
Any such closing shall be at such time of day and place as shall be mutually
agreed between such holder and AmPaM. At such closing AmPaM shall make payment
for the AmPaM Stock to be repurchased by wire transfer of immediately available
funds to a bank account designated by such Stockholder for such purpose and
such Stockholder shall deliver to AmPaM certificates, duly endorsed for
transfer, representing the shares of AmPaM Stock to be purchased and sold
pursuant to the exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger
or consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any, which are then held by persons other than the holders of AmPaM Common
Stock as of the Closing Date constitute 50% or more of AmPaM Common Stock
outstanding as of the date of the consummation of such transaction.

19.      GENERAL

         19.1 COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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 AmPaM on and after the Closing 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 Closing Date.

         19.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law and except as

benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

         19.3 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

respective Boards of Directors. Any disclosure made on any Schedule delivered
pursuant hereto shall be deemed to have been disclosed for purposes of any

faith effort to cross reference disclosure, as necessary or advisable, between
related Schedules.

         19.4 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. A
telecopied facsimile of an executed counterpart of this Agreement shall be
sufficient to evidence the binding agreement of each party to the terms hereof.
However, each party agrees to return to the other parties an original, duly
executed counterpart of this Agreement promptly after delivery of a telecopied
facsimile thereof.

         19.5 BROKERS AND AGENT. Except as disclosed on Schedule 18.5, each
party hereto 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.

         19.6 EXPENSES. Whether or not the transactions herein contemplated
shall be consummated, AmPaM will pay the reasonable fees, expenses and

subject matter of this Agreement except that (i) the Company shall not be
required to pay any of the costs, fees and expenses specified above as to which
AmPaM is responsible for the payment thereof and (ii) neither the Company nor
the Stockholders shall be responsible for the payment of the costs, fees and
expenses incurred by or on behalf of AmPaM. Whether or not the transactions

AmPaM funds to pay any such fees, expenses and disbursements, provided that
such reimbursement and loan repayment obligation shall be limited to the

herein, no delay of or omission in the exercise of any right, power or remedy
accruing to any party as a result of any breach or default by any other party
under this Agreement shall impair any such right, power or remedy, nor shall it
be construed as a waiver of or acquiescence in any such breach or default, or

provisions of this Agreement shall not in any way be affected or impaired
thereby. No provision of this Agreement shall be interpreted or construed
against any party solely because that party or its legal representative drafted

Stock and each future holder of such AmPaM Stock. Any consent of the
Stockholders who would receive a majority of the Aggregate Consideration
pursuant to Section I of Annex I of this Agreement if the transactions
contemplated hereby were consummated shall be deemed to be the consent of the
Stockholders for purposes of provisions of this Agreement as to which a consent
of the Stockholders may be requested or required.

Association in accordance with its then prevailing Commercial Arbitration
Rules. The enforcement, interpretation and procedural and substantive effect of

pay any dividend or make any distribution in respect thereof. The material terms

referred to in the preceding sentence will be as described in the Private
Placement Memorandum.

         6.5 SUBSIDIARIES. As of the date of this Agreement, AmPaM has no
subsidiaries. As of the date of this Agreement, AmPaM does not own, of record or
beneficially, or control, directly or indirectly, any capital stock, securities
convertible into capital stock or any other equity interest in any corporation,
association or business entity, and AmPaM is not, directly or indirectly, a
participant in any joint venture, partnership or other non-corporate entity.

         6.6 FINANCIAL STATEMENTS. The historical financial statements of AmPaM
included in the Private Placement Memorandum (the "AmPaM Financial Statements")
have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods indicated (except as noted thereon), and the balance
sheet included therein presents fairly the financial position of AmPaM as of its
date. Management of AmPaM believes that the assumptions underlying the pro forma
adjustments utilized in the preparation of such pro forma financial statements
are reasonable, and such pro forma adjustments have been properly applied to the
historical financial amounts in the compilation of the pro forma financial
statements. Based on the representations in Section 5.9 of this Agreement and in
Section 5.9 of each of the Other Agreements, the pro forma financial information
of AmPaM fairly presents the pro forma financial position, results of operations
and other information purported to be shown therein at the respective dates and
for the respective periods specified.

Placement Memorandum, as of the date of this Agreement, AmPaM has no material
liabilities or obligations of any kind, character or description, whether
accrued, absolute, secured or unsecured, contingent or otherwise, other than
liabilities incurred in the ordinary course of business and consistent with past
practices, liabilities or obligations set forth in or contemplated by this
Agreement and the Other Agreements and except for fees incurred in connection
with the transactions contemplated hereby and thereby.

governmental department, commission, board, bureau, agency or instrumentality
having jurisdiction over it and its stockholders and, there are no claims,
actions, suits or proceedings, pending or, to the knowledge of AmPaM, threatened
against or affecting, AmPaM, at law or in equity, or before or by any Federal,
state, municipal or other governmental department, commission, board, bureau,
agency or instrumentality having jurisdiction over it and no notice of any
claim, action, suit or proceeding, whether pending or threatened, has been
received. AmPaM has conducted and is conducting its businesses in compliance in

         10.2 PRESERVATION OF TAX AND ACCOUNTING TREATMENT. Except as
contemplated by this Agreement, after the Closing Date, AmPaM shall not and

(but not cash or other property), including without limitation:

                  (a) the retirement or reacquisition, directly or indirectly,
of all or part of the AmPaM Stock issued in connection with the transactions

on the Financial Statements) with respect to the Company's operations for all
periods through and including the Closing Date.

                  (b) AmPaM shall file or cause to be filed all separate Returns
of, or that include, any Acquired Party for all taxable periods ending after the

                  (c) Unless required by applicable law, regulations or
government proceedings, AmPaM shall not take any action, including any amendment

Tax liabilities payable by any of the Stockholders for periods ending on or

                  (d) Each party hereto shall, and shall cause its subsidiaries
and Affiliates to, provide to each of the other parties hereto such cooperation
and information as any of them


                                       39

<PAGE>   48


reasonably may request in filing any Return, amended Return or claim for refund,

information shall include providing copies of all relevant portions of relevant
Returns, together with relevant accompanying schedules and relevant work papers,

Authorities and relevant records concerning the ownership and Tax basis of
property, which such party may possess. Each party shall make its employees

Agreement shall bear all costs of filing such Returns.

                  (e) Each of the Company, AmPaM and each Stockholder shall
comply with the tax reporting requirements of Section 1.351-3 of the Treasury
Regulations promulgated under the Code, and treat the transaction as a tax-free

recognized on the receipt of cash or other property under Section 351(b) of the
Code.

                                       40

<PAGE>   49


as a result of or arising from (i) any breach of the representations and
warranties of the Company set forth herein or on the schedules attached hereto
or certificates delivered pursuant to this Agreement, (ii) any breach of any
covenant or agreement on the part of the Company under this Agreement, or (iii)

statement or alleged untrue statement of a material fact relating solely to the
Company which was based upon information provided to AmPaM or its counsel in
writing by the Company specifically for inclusion in the Private Placement
Memorandum and is contained in the Private Placement Memorandum, 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 required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that no Stockholder shall be liable
for any indemnification obligation pursuant to this Section 11.1 in excess of
such Stockholder's pro rata share thereof determined by reference to the
aggregate value of the Base Cash Amount (as defined in Annex I of this
Agreement), the principal amount of AmPaM Notes and the shares of AmPaM Stock
(valued at a price of $13.00 per share) received by such Stockholder pursuant to
Section I.A. of Annex I hereto (without giving effect to the adjustments
provided in Sections I.B. and I.C. thereof) (giving effect to the value of such
AmPaM Stock and without giving effect to such adjustments, collectively, the
"Aggregate Consideration") such Stockholder would receive pursuant to Section I
of Annex I of this Agreement if the transactions contemplated hereby were
consummated in relation to the total Aggregate Consideration all Stockholders
would receive pursuant to Section I of Annex I of this Agreement if the
transactions contemplated hereby were consummated.

         (b) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement, 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 AmPaM as a result of or arising from (i)
any breach of the representations and warranties of such Stockholder set forth
in Section 5(B) hereof, (ii) any breach of any covenant or agreement on the part
of such Stockholder under this Agreement, or (iii) any liability under the 1933

statement of a material fact relating solely to such Stockholder which was based
upon information provided to AmPaM or its counsel in writing by such Stockholder
specifically for inclusion in the Private Placement Memorandum and is contained
in the Private Placement Memorandum, 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 solely to such Stockholder required to be
stated therein or necessary to make the statements therein in light of the
circumstances in which such statements were made not misleading.

         (c) AmPaM acknowledges and agrees that other than the representations
and warranties of the Company or the Stockholders specifically contained in this
Agreement, there are no representations or warranties of the Company or the
Stockholders, either express or implied, with


                                       41

<PAGE>   50


respect to the transactions contemplated by this Agreement, the Company or its
assets, liabilities and business.

         11.2 INDEMNIFICATION BY AMPAM. AmPaM covenants and agrees that it will
indemnify, defend, protect and hold harmless the Company and the Stockholders at
all times from and after the date of this Agreement until the applicable
Expiration Date (as defined in the introductory paragraph of Section 6, provided
that for purposes of clause (iii) below, the applicable 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 the
Company or the Stockholders as a result of or arising from (i) any breach by
AmPaM of its representations and warranties set forth herein or on the schedules
attached hereto or certificates delivered pursuant to this Agreement, (ii) any
breach of any agreement on the part of AmPaM under this Agreement; or (iii) any
liability under the 1933 Act or any Federal or state securities 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 contained in the
Private Placement Memorandum, 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 required to be stated therein or necessary to make the statements
therein not misleading, except to the extent such is based upon an untrue
statement or alleged untrue statement, or omission or alleged omission, made
therein in reliance upon, and in conformity with, the representations and
warranties of the Company or the Stockholders specifically contained in this
Agreement or other information furnished to AmPaM by the Company or the
Stockholders in writing specifically for inclusion therein.

         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, 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 reasonably
satisfactory to the Indemnified Party, 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 or a conflict of
interest is reasonably likely


                                       42

<PAGE>   51


to arise that prevents counsel for the Indemnifying Party from representing such
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, 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. 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 pay the
Indemnified Party for the settlement amount 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. With respect to any account, note or other
receivable as to which the Stockholders have paid in full any indemnification
obligation pursuant to this Section 11 as a result of a breach of the
representation and warranty made pursuant to Section 5.11 or as to which a claim
in respect thereof has been asserted pursuant to this Section 11 that has been
applied against the Indemnification Threshold with respect to the Stockholders
as a result of a breach of the representation and warranty made pursuant to
Section 5.11, AmPaM shall cause the Company to assign such account, note or
other receivable to the Stockholders. 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. 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 to this Agreement with respect to any
provision of this Agreement, provided that, nothing herein shall be construed to
limit the right of a party, in a proper case, to seek injunctive relief for a
breach of this Agreement. AmPaM hereby waives, to the fullest extent permitted
under applicable law, any and all other rights, claims and causes of action,
known or unknown, it or any indemnified person may have against the Company or
any Stockholder relating to this Agreement or the transactions pursuant to this


                                       43

<PAGE>   52


Agreement arising under or based upon any Federal, state, local or foreign
statute, law, rule, regulation or otherwise. 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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2 (calculated as provided in this Section 11.5) plus (iii) the
principal amount of the AmPaM Notes delivered to the Stockholders pursuant to
Section 1.2, or (b) $50,000 (the "Indemnification Threshold"). Stockholders
shall not assert any claim for indemnification hereunder against AmPaM until
such time as, and solely to the extent that, the aggregate of all claims which
Stockholders may have against AmPaM shall exceed $50,000; provided, however,
that this sentence shall not be applicable with respect of any failure by AmPaM
to (i) deliver the consideration specified in Annex I hereto on the Closing Date
upon the satisfaction, or waiver by AmPaM, of all conditions to the occurrence
of the Closing Date specified in Section 9 or (ii) comply with its obligations
pursuant to Section 10.1. After the $50,000 threshold for AmPaM (subject to the
proviso in the preceding sentence) or the Indemnification Threshold for a
Stockholder has been met, all claims must be made in $10,000 increments, which
claims may be cumulated in order to meet such $10,000 thresholds. For purposes
of this paragraph, the AmPaM Stock delivered to the Stockholders shall be valued
at $13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is directly
or indirectly related to a breach by such person of any representation,
warranty, covenant or other agreement set forth in this Agreement. No claim for
indemnification against the Stockholders shall limit, diminish or change any
obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at $13.00
per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of AmPaM
Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration


                                       44

<PAGE>   53


paid to such Stockholder by AmPaM to such Stockholder pursuant to Annex I. For
the purpose of crediting Stockholders for payments made to AmPaM by means of
delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued at $13.00 per
share.

         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary of
AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM shall use commercially reasonable
efforts to pursue any available insurance coverage or other rights of indemnity
or reimbursement from third parties with respect to any such loss, liability or
expense.

12.      TERMINATION OF AGREEMENT

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

                  (i) by mutual consent of AmPaM and the Stockholders;

                  (ii) by the Stockholders, if the transactions contemplated by
         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by the Company
         or the Stockholders prior to or on the Closing Date;

                  (iii) by AmPaM, if the transactions contemplated by this
         Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by AmPaM prior
         to or on the Closing Date;

                  (iv) by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein
         relating to AmPaM, and the curing of such default shall not have been
         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v) by AmPaM, if a material breach or default shall be made by
         the Company or the Stockholders in the observance or in the due and
         timely performance of any of the covenants or agreements contained
         herein relating to the Company or the Stockholders, and the curing of
         such default shall not have been made (or in the reasonable judgment of
         AmPaM cannot be made) on or before the Closing Date;


                                       45

<PAGE>   54


                  (vi) by the Stockholders, if the conditions set forth in
         Section 8 hereof have not been satisfied or waived as of the Closing
         Date; or

                  (vii) by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2 PROCEDURE AND EFFECT OF TERMINATION. A determination to terminate
this Agreement by AmPaM pursuant to Section 12.1 shall be valid and effective
only if a written notice of termination, accompanied by a certified copy of
resolutions of the board of directors of AmPaM that evidence the authorization
of the officer of AmPaM to deliver a written notice of termination of this
Agreement pursuant to Section 12.1, is given to the Stockholders in the manner
specified for notices in this Agreement. A determination to terminate this
Agreement by the Stockholders pursuant to Section 12.1 shall be valid and
effective only if a written notice of termination, signed by Stockholders who
would be entitled to receive a majority of the shares of AmPaM Stock specified
in Section I of Annex I to this Agreement if the transactions contemplated
hereby were consummated, is given to AmPaM in the manner specified for notices
in this Agreement. Upon the giving of notice of termination of this Agreement
pursuant to Section 12.1 as specified in the preceding sentence, this Agreement
shall terminate, and the transactions contemplated hereby shall be abandoned,
without further action by any of the parties hereto. Immediately upon any such
termination, AmPaM shall deliver written notice of such termination to the Other
Founding Companies. If this Agreement is terminated as provided in this Section
12, no party hereto shall have any liability or further obligation hereunder to
any other party, except as provided in Section 14 and Section 18.6, provided,
that, 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 that occurred prior to such termination.

13.      NONCOMPETITION

         13.1 PROHIBITED ACTIVITIES. The Stockholders will not, without the
prior written consent of AmPaM, for a period of two (2) years following the
Closing 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) 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, whether paid or unpaid, in any plumbing, piping,
         mechanical, heating, ventilation or air conditioning contracting,
         installation or services business or operation, whether for
         residential, commercial, industrial or governmental customers, or any
         ancillary contracting, installation or services business directly
         related thereto (such business and operations referred to herein as the
         "Plumbing and Mechanical


                                       46

<PAGE>   55


         Business"), within 100 miles of where the Company or any of its
         subsidiaries conducted business within two (2) years prior to the
         Closing Date (the "Territory");

                  (ii) call upon any person who is, at the Closing Date, within
         the Territory, an employee of AmPaM or any subsidiary thereof for the
         purpose or with the intent of enticing such employee away from or out
         of the employ of AmPaM or any subsidiary thereof;

                  (iii) call upon any person or entity which is, at the Closing
         Date, or which has been within three (3) years prior to the Closing
         Date, a customer of AmPaM or any subsidiary thereof, of the Company or
         of any of the Other Founding Companies for the purpose of soliciting
         customers, orders or contracts for any Plumbing and Mechanical Business
         in direct competition with AmPaM within the Territory;

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

                  (v) disclose to any person, firm, partnership, corporation or
         business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or any
         of its subsidiaries within the two (2) years prior to the Closing Date
         for any reason or purpose whatsoever except to the extent that the
         Company has in the past disclosed such information to the public for
         valid business reasons; or

                  (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

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


                                       47

<PAGE>   56


         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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by AmPaM of such
covenants. It is specifically agreed that the period of two (2) 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
found to be in violation of any provision of this Section 13 as determined by
any of (i) a written agreement to such effect executed and delivered by AmPaM
and such Stockholder, (ii) a determination by an arbitration panel pursuant to
an arbitration conducted pursuant to Section 18.16 hereof or (iii) a
non-appealable judgment of a court of competent jurisdiction. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto. The covenants contained in Section 13
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
the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and pricing and cost
policies that are valuable, special and unique assets of the Company's, the
Other Founding Companies' and/or AmPaM'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 AmPaM, (b) following the
Closing, such information may be disclosed by the Stockholders as is required in
the course of performing their duties for AmPaM or the Company and (c) to its
counsel and other advisers, provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 14.1; provided, however
that (i) the foregoing


                                       48

<PAGE>   57


disclosure prohibition shall not apply in the event that (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 AmPaM and provide AmPaM 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, AmPaM 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
AmPaM 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 AMPAM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies that
are valuable, special and unique assets of the Company's business. AmPaM agrees
that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes known
to the public generally through no fault of AmPaM, (B) 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 (B), AmPaM
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 (C) 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 AmPaM of
the provisions of this Section 14.2, the Company and the Stockholders shall be
entitled to an injunction restraining AmPaM 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.
In the event the transactions contemplated by this Agreement are not consummated
for any reason, AmPaM shall nevertheless remain subject to this Section 14.2,
except that it shall not be permitted to make any disclosures otherwise than
pursuant to clause (A), (B) or (C) above.


                                       49

<PAGE>   58


         14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

         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 Closing Date.

         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AMPAM STOCK AND AMPAM NOTES. For
a period of two years from the Closing Date or, in the event that the Company
completes an IPO, for a period through the second anniversary of the date of the
closing of such IPO (the "Restricted Period"), no Stockholder shall (i) sell,
assign, exchange, transfer, pledge, or otherwise dispose of any shares of AmPaM
Stock or AmPaM Notes received by the Stockholders pursuant to this Agreement or
any securities convertible into, exchangeable or exercisable for any shares of
AmPaM Stock or AmPaM Notes received by such Stockholder pursuant to this
Agreement, (ii) grant any option to purchase, or otherwise enter into any
contract to sell, assign, transfer, pledge or otherwise dispose of, any shares
of AmPaM Stock or AmPaM Notes received by such Stockholder pursuant to this
Agreement, or (iii) enter into any swap or any other agreement or any
transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of the AmPaM Stock or AmPaM Notes, whether any
such swap or transaction is to be settled by delivery of shares of AmPaM Stock
or AmPaM Notes or other securities, by the delivery or payment of cash or
otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A) as
otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock, pursuant
to Section 17 hereof, (C) for transfers to (I) immediate family members of such
Stockholder who agree with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1, (II) trusts, limited partnerships or other estate
planning entities for the benefit of such Stockholder or family members of such
Stockholder which have agreed with AmPaM in writing, through action taken by the
trustees, partners or other persons having authority to bind the trust, limited
partnership or other estate planning entity, to be bound by the restrictions set
forth in this Section 15.1, (III) any charitable organization that qualifies for
receipt of charitable contributions under Section 170(c) of the Code which
agrees with AmPaM in writing to be bound by the restrictions set forth in this
Section 15.1, (D) for transfers of AmPaM Stock or AmPaM Notes to AmPaM pursuant
to Section 11.5(d), (E) for transfers to another Stockholder, to another person
or entity who receives shares of AmPaM Stock or AmPaM Notes or AmPaM Series A
Preferred Stock pursuant to the Other Agreements or to Sterling City Capital LLC
or any of its Affiliates provided that (1) such transaction is exempt from the
registration requirements of the 1933 Act as evidenced by the delivery to AmPaM
of an opinion of counsel in form and substance reasonably satisfactory to AmPaM
and


                                       50

<PAGE>   59


(2) any such transferee agrees in writing to be bound by the restrictions set
forth in this Section 15.1, (F) transfers of shares of AmPaM Notes, shares of
AmPaM Stock, or grants of options to purchase shares of AmPaM Stock, by such
Stockholder to employees of the Company of up to an aggregate of 15% of the
shares of AmPaM Stock received by such Stockholder pursuant to this Agreement
provided that (1) any such transaction is exempt from the registration
requirements of the 1933 Act as evidenced by the delivery to AmPaM of an opinion
of counsel in form and substance reasonably satisfactory to AmPaM and (2) any
such employee agrees with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1 or (G) the sale by such Stockholder in an IPO of
shares of AmPaM Stock representing not more than 10% of the Aggregate
Consideration in cash; provided, however, that in no circumstance will a
Stockholder be entitled to sell shares of AmPaM Stock in an IPO to the extent
that the sale of such shares by such Stockholder would result in such
Stockholder receiving in excess of 45% of the Aggregate Consideration in cash;
and, provided further, if AmPaM 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 Section 17.1 that the number of
shares to be sold by persons other than AmPaM is greater than the number of such
shares which can be offered without adversely affecting the success of the
offering, AmPaM may reduce pro rata (among the Stockholders and all other
selling security holders in the offering) 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. During the
Restricted Period, the certificates evidencing the AmPaM Stock or AmPaM Notes
delivered to the Stockholders pursuant to Section 3 of this Agreement will bear
a legend substantially in the form set forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION
OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly


                                       51

<PAGE>   60


or indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the shares
of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to be
delivered to such 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 sold, assigned, exchanged, transferred, pledged or
otherwise disposed of without compliance with the 1933 Act which, among other
matters, would require registration under the 1933 Act unless exemption from the
registration requirements is available for such transaction. The AmPaM Stock,
the Additional Consideration Right and any AmPaM Notes to be acquired by each
Stockholder pursuant to this Agreement is being acquired solely for such
Stockholder's own account, for investment purposes only, and with no present
intention of selling, assigning, exchanging, transferring, pledging, or
otherwise disposing of it. Each Stockholder covenants, warrants and represents
that neither the shares of AmPaM Stock, the Additional Consideration Right nor
any AmPaM Notes issued to such Stockholder will be offered, sold, assigned,
exchanged, pledged, 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 certificates representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision), and
is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of the
nature described in the preceding sentence and all questions have been answered
to such Stockholder's satisfaction. Except as set forth on Schedule 16.2, each
Stockholder is an "accredited investor" as defined in Rule 501(a) of the 1933
Act. Neither the foregoing nor any investigation made by the Stockholders
referred to above shall in any way affect the representations, warranties,


                                       52

<PAGE>   61


covenants and agreements of AmPaM made herein except to the extent that AmPaM is
relying upon the representations of the Stockholders in Section 16.1 and in this
Section 16.2 for purposes of AmPaM's representations and warranties in Sections
6.9, 6.11, 6.15 and 6.17 hereof as specified therein.

         16.3 RELIANCE BY AMPAM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to register
any AmPaM Stock for its own or other's 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 AmPaM and (ii)
registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other distribution with respect
to, or in exchange for, or in replacement of such AmPaM Stock) which any such
Stockholder requests, other than shares of AmPaM Stock which may then be
immediately sold under Rule 144(k) (or any similar or successor provision)
promulgated under the 1933 Act, and other than shares of AmPaM Stock that have
been theretofore sold by the Stockholder in accordance with the 1933 Act,
provided that AmPaM shall have the right to reduce pro rata the number of shares
of each selling Stockholder included in such registration to the extent that
inclusion of such shares would, in the written opinion of tax counsel to AmPaM
or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Private Placement Memorandum as a tax-free
organization under Section 351 of the Code; provided, however, that with respect
to a proposal by AmPaM to register AmPaM Stock under the 1933 Act in connection
with an IPO, no Stockholder shall be permitted pursuant to this Section 17.1 to
have included in such registration more shares of AmPaM Stock than permitted to
be sold by such Stockholder pursuant to Section 15.1. In addition, if AmPaM 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 AmPaM is greater than the number of such shares which can be offered
without adversely affecting the success of the offering, AmPaM may reduce pro
rata (among the Stockholders and all other selling security holders in the
offering) 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. If any Stockholder disapproves of the terms of the
underwriting, that Stockholder may elect to withdraw therefrom by written notice
to AmPaM and the managing underwriter. That


                                       53

<PAGE>   62


Stockholder's shares of AmPaM Stock so withdrawn shall also be withdrawn from
registration; provided, however, that, if by the withdrawal of such shares a
greater number of shares of AmPaM Stock held by other Stockholders may be
included in such registration, then AmPaM shall offer to all other Stockholders
of AmPaM the right to include additional shares in the same proportion used in
effecting the above limitations. AmPaM shall not, for a period of two years
following the Closing Date, grant to any other person any rights to cause AmPaM
to register any securities in priority over, or in precedent to, the rights
granted to the Stockholders hereunder and to the stockholders of the Other
Founding Companies pursuant to Section 17 of the Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a representative of the
         Stockholders with copies of all such documents proposed to be filed) as
         promptly as practical;

                  (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such registration statement or supplement to the prospectus;

                  (iv) 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;

                  (v) Make "generally available to its security holders" (within
         the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;


                                       54

<PAGE>   63


                  (vi) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of the registration statement at
         the earliest possible moment;

                  (vii) If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment such
         information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM Stock being sold by
         participating Stockholders to any underwriter or underwriters, the
         purchase price being paid therefor by such underwriter or underwriters
         and with respect to any other terms of an underwritten offering of the
         shares of AmPaM Stock to be sold in such offering, and promptly make
         all required filings of such prospectus by supplement or post-effective
         amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition pursuant
         to such registration statement, and the counsel retained by the
         participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or any
         such underwriter (collectively, the "Inspectors"), all financial and
         other records, pertinent corporate documents and properties of AmPaM
         (the "Records"), as shall be reasonably necessary to enable them to
         exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x) 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 required to
         be kept effective, provided that AmPaM shall not be required to become
         subject to taxation, to qualify generally to do business or to file a
         general consent to service of process in any such states or
         jurisdictions;

                  (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any


                                       55

<PAGE>   64


         securities exchanges or trading systems on which similar securities
         issued by AmPaM are then listed or included; and

                  (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in effect),
         together with any associated term sheet, contains an untrue statement
         of a material fact or omits to state any fact required to be stated
         therein or necessary to make the statements therein (in the case of the
         prospectus or any preliminary prospectus, in light of the circumstances
         under which they were made) not misleading, and, at the request of such
         Stockholder, AmPaM promptly 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 required to be
         stated therein or necessary to make the statements therein (in the case
         of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall be
borne by AmPaM.

         17.3     INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue statement
of material fact contained or incorporated by reference in any registration
statement, prospectus or preliminary prospectus or associated term sheet or any
omission or alleged omission to state or incorporated by reference therein a
material fact required to be stated or incorporated by reference 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 AmPaM 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 AmPaM has furnished
such Indemnified Party with a sufficient number of copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning of
the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged untrue statement of a material fact or any
omission or alleged omission to state therein a material fact required to be
stated in the registration statement or prospectus or any amendment thereof or
supplement thereto or necessary to make the statements therein not misleading,
but only to the extent that such untrue or alleged



                                       56

<PAGE>   65


untrue statement or omission or alleged omission is contained in or omitted from
information so furnished in writing to AmPaM by such Stockholder expressly for
use in 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 hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i) each
participating Stockholder shall execute and deliver to AmPaM a written power of
attorney instrument that (A) appoints an officer of AmPaM as such Stockholder's
attorney-in-fact for purposes of executing and delivering an underwriting
agreement among AmPaM, the underwriters named therein and such Stockholder
specifying the terms and conditions applicable to the sale of AmPaM Stock of
such Stockholder in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering in which
one or more stockholders of the issuer are participants, including a provision
that authorizes the attorney-in-fact appointed by such Stockholder to execute
and deliver such an underwriting agreement in the event that the net price per
share to be received by such Stockholder from the sale of the shares of AmPaM
Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters


                                       57
<PAGE>   66


specifically for inclusion in any such registration statement and (B) such
Stockholder shall not be obligated to enter into such an underwriting agreement
in the event that the net price per share to be received by such Stockholder
from the sale of shares of AmPaM Stock to be sold in such offering is less than
the floor price specified in the power of attorney instrument executed and
delivered to AmPaM pursuant to clause (i) above.

         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares of
AmPaM Stock under this Agreement may be assigned to a transferee or assignee of
any Stockholder to the extent that such transferee or assignee is a member of
the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

                  (i) make and keep public information regarding AmPaM available
         as those terms are understood and defined in Rule 144 under the 1933
         Act beginning 90 days following the effective date of a registration
         statement relating to an IPO;

                  (ii) file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 AmPaM, 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.      REDEMPTION OF AMPAM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal payments,
if any, made with respect to AmPaM Notes held by such Stockholder) equal to or
exceeding 50% of the Aggregate Consideration on or prior to the third
anniversary of the Closing Date, such Stockholder shall have the right (the "Put
Right"), but not the


                                       58

<PAGE>   67


obligation, commencing on the third anniversary date of the Closing Date to
require AmPaM to purchase a number of shares of AmPaM Stock then owned by such
Stockholder, subject to the limitations set forth in Section 18.2 below. The
purchase price for such redemption shall be $13.00 per share, such price to be
subject to appropriate adjustment to reflect any reclassification, stock
dividend, subdivision, split-up or combination of shares of AmPaM Stock after
the date hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified, AmPaM
shall be obligated to purchase from each eligible Stockholder no less than 10%
of the AmPaM Stock held by such Stockholder annually; provided, however, that
the Stockholders shall not be entitled to exercise their Put Rights if and to
the extent the Company has not achieved the Target Net Income (as defined in
Annex I hereto) for the year preceding the year in which a Stockholder seeks to
exercise his Put Right. The redemptions will be funded by internal cash flows or
alternative financing arrangements but AmPaM's obligation to make any redemption
pursuant to this Section 18 will be subject to the covenants and restrictions
contained in AmPaM's then existing private or public debt or equity instruments.

         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right by
giving written notice (the "Put Notice") to AmPaM within thirty (30) days of the
third anniversary of the execution hereof. If any Stockholder does not provide
AmPaM with a Put Notice within such thirty-day period, the Put Right applicable
to such Stockholder shall expire. The date for closing the sale of any shares of
AmPaM Stock pursuant to a proper exercise of a Put Right shall in no event be
earlier than 90 days after the date AmPaM receives the Put Notice. Any such
closing shall be at such time of day and place as shall be mutually agreed
between such holder and AmPaM. At such closing AmPaM shall make payment for the
AmPaM Stock to be repurchased by wire transfer of immediately available funds to
a bank account designated by such Stockholder for such purpose and such
Stockholder shall deliver to AmPaM certificates, duly endorsed for transfer,
representing the shares of AmPaM Stock to be purchased and sold pursuant to the
exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger or
consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any,


                                       59

<PAGE>   68


which are then held by persons other than the holders of AmPaM Common Stock
as of the Closing Date constitute 50% or more of AmPaM Common Stock outstanding
as of the date of the consummation of such transaction.

19.      GENERAL

         19.1 COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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
AmPaM on and after the Closing 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 Closing Date.

         19.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law and except as
provided in Section 17.5) and shall be binding upon and shall inure to the
benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

         19.3 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 and AmPaM 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 by
a written instrument executed by the Stockholders, the Company and AmPaM, 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.

         19.4 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. A telecopied
facsimile of an executed counterpart of this Agreement shall be sufficient to
evidence the binding agreement of each party to the terms hereof. However, each
party agrees to return to the other parties an original, duly executed
counterpart of this Agreement promptly after delivery of a telecopied facsimile
thereof.

of the Closing or in writing delivered pursuant to the provisions of this

herein, no delay of or omission in the exercise of any right, power or remedy
accruing to any party as a result of any breach or default by any other party

occurring before or after that waiver.

         19.11 TIME. Time is of the essence with respect to this Agreement.

         19.12 REFORMATION AND SEVERABILITY. In case any provision of this
Agreement shall be invalid, illegal or unenforceable, it shall, to the extent
possible, be modified in such manner as to be valid, legal and enforceable but

is not possible, such provision shall be severed from this Agreement, and in
either case the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby. No provision of this Agreement shall be interpreted or construed

in connection with the purchase and sale of the Company Stock and each future
holder of such AmPaM Stock. Any consent of the Stockholders who would receive a
majority of the Aggregate Consideration pursuant

<PAGE>   72


to Section I of Annex I of this Agreement if the transactions contemplated
hereby were consummated shall be deemed to be the consent of the Stockholders
for purposes of provisions of this Agreement as to which a consent of the
Stockholders may be requested or required.

         19.16 MEDIATION AND ARBITRATION. If a dispute arises out of or relates
to this Agreement, or the breach thereof, and if said dispute cannot be settled
through direct discussions, the parties agree to first endeavor to settle the
dispute in an amicable manner by mediation administered by the American
Arbitration Association under its then prevailing Commercial Mediation Rules,
before resorting to arbitration. Thereafter, any unresolved controversy or claim
arising out of or relating to this Agreement, or the breach thereof, shall be
settled by arbitration administered by the American Arbitration Association in
accordance with its then prevailing Commercial Arbitration Rules. The
enforcement, interpretation and procedural and substantive effect of the
obligation to arbitrate created by this Section 19.16 shall be governed by the
Federal Arbitration Act as amended from time to time, 9 U.S.C. Section 1 et seq.
The parties hereby disclaim any intention to have the substantive or procedural
law of any state or other jurisdiction, other than the law of the United States
as embodied in the Federal Arbitration Act, applied to such obligation. Any such
mediation or arbitration proceeding will be conducted in Houston, Texas.

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" shall have the same meaning as is given that

will not as a result of its past activities become, liable to the Pension
Benefit Guaranty Corporation 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(a) and the
administration thereof are in compliance in all material respects 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 as of the Balance
Sheet Date with respect to any plan listed on Schedule 5.19(a) have either been
fulfilled in their entirety or are fully reflected on the balance sheet of the
Company as of the Balance Sheet Date.

         5.20 COMPLIANCE WITH ERISA. All plans listed on Schedule 5.19(a) that
are intended to qualify under Section 401 (a) of the Code (the "Qualified
Plans") are, and have been so qualified and have been determined by the Internal
Revenue Service to be so qualified, and copies of such determination letters are
attached to Schedule 5.19(a). 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) since January 1, 1992 have been
timely filed or distributed, and copies thereof have been made available to
AmPaM. No such plan listed on Schedule 5.19(a) 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 on Schedule 5.19(a) 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 Pension Benefit Guaranty Corporation. The Company further represents that
except as set forth on Schedule 5.20 hereto:

                  (i) there have been no terminations, partial terminations or
         discontinuations of contributions to any Qualified Plan intended to
         qualify under Section 401(a) of the Code without notice to and approval

         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(a);

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

                  (v) no circumstances exist pursuant to which the Company could
         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.

organized, validly existing and in good standing under the laws of the State of
Delaware, and has the requisite power and authority to carry on its business as
it is now being conducted and as contemplated by the Private Placement
Memorandum. AmPaM is duly qualified or authorized to do business and is in good
standing in each jurisdiction in which the nature of its business or the
ownership or leasing of its properties makes such qualification or authorization
necessary, except where the failure to be so qualified or authorized to do
business would not have a Material Adverse Effect. True, complete and correct
copies of the Certificate of Incorporation and By-laws, each as proposed to be
amended and as such documents shall be in effect as of the Closing Date, of
AmPaM (the "AmPaM Charter Documents") are attached hereto as Annex II.

         6.2 AUTHORIZATION. (i) The officers of AmPaM executing this Agreement
have the authority to enter into and bind AmPaM to the terms of this Agreement
and (ii) AmPaM has the full legal right, power and authority to enter into this
Agreement and consummate the transactions contemplated hereby. All corporate
acts and other proceedings required to have been taken by AmPaM to authorize the
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby have been duly and properly taken.

         6.3 CAPITAL STOCK OF AmPaM. The authorized capital stock of AmPaM is as
set forth in Section 1.3(ii). Immediately prior to the Closing Date, all of the
issued and outstanding shares of the capital stock of AmPaM will be as set forth
in the Private Placement Memorandum, free and clear of all liens, security
interests, pledges, charges, voting trusts, restrictions, encumbrances and
claims of every kind other than any restrictions described in the Private
Placement Memorandum. All of the issued and outstanding shares of the capital
stock of AmPaM have been duly authorized and validly issued, are fully paid and
nonassessable and such shares were offered, issued, sold and delivered by AmPaM
in compliance with all applicable state and Federal laws concerning the issuance
of securities. Further, none of such shares were issued in violation of the
preemptive rights of any past or present stockholder of AmPaM. Upon the Closing
Date, the authorized, issued and outstanding shares of capital stock of AmPaM
will be as set forth in the Private Placement Memorandum under the caption
"Capitalization." Upon the Closing Date, the aggregate number of shares of AmPaM
Stock issued and outstanding on the Closing Date that are owned by Sterling City
Capital, LLC, any Affiliates of Sterling City Capital, LLC and the officers and
directors of AmPaM will not be greater than the number of shares of AmPaM Stock
reflected in the Private Placement Memorandum as the aggregate number of shares
of AmPaM Stock to be issued and outstanding and owned by Sterling City Capital,
LLC, any Affiliates of Sterling City Capital, LLC and the officers and directors
of AmPaM.

         6.4 TRANSACTIONS IN CAPITAL STOCK. Except for the Other Agreements and
except as set forth in the Private Placement Memorandum, (i) no option, warrant,
call, conversion right or commitment of any kind exists as of the date of this
Agreement which obligates AmPaM to issue any of its authorized but unissued
capital stock; and (ii) AmPaM has no obligation (contingent or otherwise) to
purchase, redeem or otherwise acquire any of its equity securities or any
interests therein or to pay any dividend or make any distribution in respect
thereof. The material terms of any

<PAGE>   33



options, warrants or other rights to acquire shares of the stock of AmPaM
referred to in the preceding sentence will be as described in the Private
Placement Memorandum.

         6.5 SUBSIDIARIES. As of the date of this Agreement, AmPaM has no
subsidiaries. As of the date of this Agreement, AmPaM does not own, of record or
beneficially, or control, directly or indirectly, any capital stock, securities
convertible into capital stock or any other equity interest in any corporation,
association or business entity, and AmPaM is not, directly or indirectly, a
participant in any joint venture, partnership or other non-corporate entity.

         6.6 FINANCIAL STATEMENTS. The historical financial statements of AmPaM
included in the Private Placement Memorandum (the "AmPaM Financial Statements")
have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods indicated (except as noted thereon), and the balance
sheet included therein presents fairly the financial position of AmPaM as of its
date. Management of AmPaM believes that the assumptions underlying the pro forma
adjustments utilized in the preparation of such pro forma financial statements
are reasonable, and such pro forma adjustments have been properly applied to the
historical financial amounts in the compilation of the pro forma financial
statements. Based on the representations in Section 5.9 of this Agreement and in
Section 5.9 of each of the Other Agreements, the pro forma financial information
of AmPaM fairly presents the pro forma financial position, results of operations
and other information purported to be shown therein at the respective dates and
for the respective periods specified.

         6.7 LIABILITIES AND OBLIGATIONS. Except as set forth in the Private
Placement Memorandum, as of the date of this Agreement, AmPaM has no material
liabilities or obligations of any kind, character or description, whether
accrued, absolute, secured or unsecured, contingent or otherwise, other than
liabilities incurred in the ordinary course of business and consistent with past
practices, liabilities or obligations set forth in or contemplated by this
Agreement and the Other Agreements and except for fees incurred in connection
with the transactions contemplated hereby and thereby.

         6.8 CONFORMITY WITH LAW; LITIGATION. Except to the extent set forth in
the Private Placement Memorandum, AmPaM is not in violation of any law or
regulation or any order of any court or Federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality
having jurisdiction over it and its stockholders and, there are no claims,
actions, suits or proceedings, pending or, to the knowledge of AmPaM, threatened
against or affecting, AmPaM, at law or in equity, or before or by any Federal,
state, municipal or other governmental department, commission, board, bureau,
agency or instrumentality having jurisdiction over it and no notice of any
claim, action, suit or proceeding, whether pending or threatened, has been
received. AmPaM has conducted and is conducting its businesses in compliance in
all material respects with the requirements, standards, criteria and conditions
set forth in applicable Federal, state and local statutes, ordinances, permits,
licenses, orders, approvals, variances, rules and regulations and is not in
violation, in any material respect, of any of the foregoing.

complied with or satisfied by such person hereunder. AmPaM shall give prompt

securities regulatory authority of any issuance of or threatened issuance of any
order challenging the availability of an exemption from registration or

otherwise affect the remedies available hereunder to the party receiving such

the consent of AmPaM or the Stockholders, as the case may be, as provided above,

deliver, or cause to be executed and delivered, such further instruments or
documents or take such other action as may be reasonably necessary or
appropriate to carry out the transactions contemplated hereby and to cause the

use its best efforts to comply with the Hart-Scott Act and (ii) such compliance
by the Stockholders and the parties agree to cooperate and use their best

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 or a conflict of
interest is reasonably likely to arise that prevents counsel for the
Indemnifying Party from representing such 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, 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



                                       42
<PAGE>   51

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. 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 pay the Indemnified Party
for the settlement amount 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. With respect to any account, note or other
receivable as to which the Stockholders have paid in full any indemnification
obligation pursuant to this Section 11 as a result of a breach of the
representation and warranty made pursuant to Section 5.11 or as to which a claim
in respect thereof has been asserted pursuant to this Section 11 that has been
applied against the Indemnification Threshold with respect to the Stockholders
as a result of a breach of the representation and warranty made pursuant to
Section 5.11, AmPaM shall cause the Company to assign such account, note or
other receivable to the Stockholders. 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. 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 to this Agreement with respect to any
provision of this Agreement, provided that, nothing herein shall be construed to
limit the right of a party, in a proper case, to seek injunctive relief for a
breach of this Agreement. AmPaM hereby waives, to the fullest extent permitted
under applicable law, any and all other rights, claims and causes of action,
known or unknown, it or any indemnified person may have against the Company or
any Stockholder relating to this Agreement or the transactions pursuant to this
Agreement arising under or based upon any Federal, state, local or foreign
statute, law, rule, regulation or otherwise. 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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2






                                       43
<PAGE>   52

(calculated as provided in this Section 11.5) plus (iii) the principal amount of
the AmPaM Notes delivered to the Stockholders pursuant to Section 1.2, or (b)
$50,000 (the "Indemnification Threshold"). Stockholders shall not assert any
claim for indemnification hereunder against AmPaM until such time as, and solely
to the extent that, the aggregate of all claims which Stockholders may have
against AmPaM shall exceed $50,000; provided, however, that this sentence shall
not be applicable with respect of any failure by AmPaM to (i) deliver the
consideration specified in Annex I hereto on the Closing Date upon the
satisfaction, or waiver by AmPaM, of all conditions to the occurrence of the
Closing Date specified in Section 9 or (ii) comply with its obligations pursuant
to Section 10.1. After the $50,000 threshold for AmPaM (subject to the proviso
in the preceding sentence) or the Indemnification Threshold for a Stockholder
has been met, all claims must be made in $10,000 increments, which claims may be
cumulated in order to meet such $10,000 thresholds. For purposes of this
paragraph, the AmPaM Stock delivered to the Stockholders shall be valued at
$13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is directly
or indirectly related to a breach by such person of any representation,
warranty, covenant or other agreement set forth in this Agreement. No claim for
indemnification against the Stockholders shall limit, diminish or change any
obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at $13.00
per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of AmPaM
Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration paid to such Stockholder by AmPaM to such Stockholder pursuant to
Annex I. For the purpose of crediting Stockholders for payments made to AmPaM by
means of delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued at
$13.00 per share.

         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary of
AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM





                                       44
<PAGE>   53

shall use commercially reasonable efforts to pursue any available insurance
coverage or other rights of indemnity or reimbursement from third parties with
respect to any such loss, liability or expense.

12.      TERMINATION OF AGREEMENT

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

                  (i) by mutual consent of AmPaM and the Stockholders;

                  (ii) by the Stockholders, if the transactions contemplated by
         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by the Company
         or the Stockholders prior to or on the Closing Date;

                  (iii) by AmPaM, if the transactions contemplated by this
         Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by AmPaM prior
         to or on the Closing Date;

                  (iv) by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein
         relating to AmPaM, and the curing of such default shall not have been
         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v) by AmPaM, if a material breach or default shall be made by
         the Company or the Stockholders in the observance or in the due and
         timely performance of any of the covenants or agreements contained
         herein relating to the Company or the Stockholders, and the curing of
         such default shall not have been made (or in the reasonable judgment of
         AmPaM cannot be made) on or before the Closing Date;

                  (vi) by the Stockholders, if the conditions set forth in
         Section 8 hereof have not been satisfied or waived as of the Closing
         Date; or

                  (vii) by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2 PROCEDURE AND EFFECT OF TERMINATION. A determination to terminate
this Agreement by AmPaM pursuant to Section 12.1 shall be valid and effective
only if a written notice of termination, accompanied by a certified copy of
resolutions of the board of directors of AmPaM that evidence the authorization
of the officer of AmPaM to deliver a written notice of termination of this
Agreement pursuant to Section 12.1, is given to the Stockholders in the manner
specified for notices





                                       45
<PAGE>   54

in this Agreement. A determination to terminate this Agreement by the
Stockholders pursuant to Section 12.1 shall be valid and effective only if a
written notice of termination, signed by Stockholders who would be entitled to
receive a majority of the shares of AmPaM Stock specified in Section I of Annex
I to this Agreement if the transactions contemplated hereby were consummated, is
given to AmPaM in the manner specified for notices in this Agreement. Upon the
giving of notice of termination of this Agreement pursuant to Section 12.1 as
specified in the preceding sentence, this Agreement shall terminate, and the
transactions contemplated hereby shall be abandoned, without further action by
any of the parties hereto. Immediately upon any such termination, AmPaM shall
deliver written notice of such termination to the Other Founding Companies. If
this Agreement is terminated as provided in this Section 12, no party hereto
shall have any liability or further obligation hereunder to any other party,
except as provided in Section 14 and Section 18.6, provided, that, 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 that occurred prior to such termination.

13.      NONCOMPETITION

         13.1 PROHIBITED ACTIVITIES. The Stockholders will not, without the
prior written consent of AmPaM, for a period of two (2) years following the
Closing 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) 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, whether paid or unpaid, in any plumbing, piping,
         mechanical, heating, ventilation or air conditioning contracting,
         installation or services business or operation, whether for
         residential, commercial, industrial or governmental customers, or any
         ancillary contracting, installation or services business directly
         related thereto (such business and operations referred to herein as the
         "Plumbing and Mechanical Business"), within 100 miles of where the
         Company or any of its subsidiaries conducted business within two (2)
         years prior to the Closing Date (the "Territory");

                  (ii) call upon any person who is, at the Closing Date, within
         the Territory, an employee of AmPaM or any subsidiary thereof for the
         purpose or with the intent of enticing such employee away from or out
         of the employ of AmPaM or any subsidiary thereof;

                  (iii) call upon any person or entity which is, at the Closing
         Date, or which has been within three (3) years prior to the Closing
         Date, a customer of AmPaM or any subsidiary thereof, of the Company or
         of any of the Other Founding Companies for the purpose of soliciting
         customers, orders or contracts for any Plumbing and Mechanical Business
         in direct competition with AmPaM within the Territory;




                                       46
<PAGE>   55

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

                  (v) disclose to any person, firm, partnership, corporation or
         business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or any
         of its subsidiaries within the two (2) years prior to the Closing Date
         for any reason or purpose whatsoever except to the extent that the
         Company has in the past disclosed such information to the public for
         valid business reasons; or

                  (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

         13.2 DAMAGES. Because of the difficulty of measuring economic losses to
AmPaM as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to AmPaM for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by AmPaM 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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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.




                                       47
<PAGE>   56

         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by AmPaM of such
covenants. It is specifically agreed that the period of two (2) 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
found to be in violation of any provision of this Section 13 as determined by
any of (i) a written agreement to such effect executed and delivered by AmPaM
and such Stockholder, (ii) a determination by an arbitration panel pursuant to
an arbitration conducted pursuant to Section 18.16 hereof or (iii) a
non-appealable judgment of a court of competent jurisdiction. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto. The covenants contained in Section 13
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
the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and pricing and cost
policies that are valuable, special and unique assets of the Company's, the
Other Founding Companies' and/or AmPaM'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 AmPaM, (b) following the
Closing, such information may be disclosed by the Stockholders as is required in
the course of performing their duties for AmPaM or the Company and (c) to its
counsel and other advisers, provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 14.1; provided, however
that (i) the foregoing disclosure prohibition shall not apply in the event that
(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 AmPaM and provide AmPaM 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, AmPaM 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 AmPaM from pursuing any other available remedy for such
breach or threatened breach, including the recovery of damages. In the event the
transactions contemplated




                                       48
<PAGE>   57

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 AmPaM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies that
are valuable, special and unique assets of the Company's business. AmPaM agrees
that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes known
to the public generally through no fault of AmPaM, (B) 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 (B), AmPaM
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 (C) 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 AmPaM of
the provisions of this Section 14.2, the Company and the Stockholders shall be
entitled to an injunction restraining AmPaM 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.
In the event the transactions contemplated by this Agreement are not consummated
for any reason, AmPaM shall nevertheless remain subject to this Section 14.2,
except that it shall not be permitted to make any disclosures otherwise than
pursuant to clause (A), (B) or (C) above.

         14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

         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 Closing Date.



                                       49
<PAGE>   58

         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AMPAM STOCK AND AMPAM NOTES. For
a period of two years from the Closing Date or, in the event that the Company
completes an IPO, for a period through the second anniversary of the date of the
closing of such IPO (the "Restricted Period"), no Stockholder shall (i) sell,
assign, exchange, transfer, pledge, or otherwise dispose of any shares of AmPaM
Stock or AmPaM Notes received by the Stockholders pursuant to this Agreement or
any securities convertible into, exchangeable or exercisable for any shares of
AmPaM Stock or AmPaM Notes received by such Stockholder pursuant to this
Agreement, (ii) grant any option to purchase, or otherwise enter into any
contract to sell, assign, transfer, pledge or otherwise dispose of, any shares

transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of the AmPaM Stock or AmPaM Notes, whether any
such swap or transaction is to be settled by delivery of shares of AmPaM Stock
or AmPaM Notes or other securities, by the delivery or payment of cash or
otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A) as
otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock, pursuant
to Section 17 hereof, (C) for transfers to (I) immediate family members of such
Stockholder who agree with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1, (II) trusts, limited partnerships or other estate
planning entities for the benefit of such Stockholder or family members of such
Stockholder which have agreed with AmPaM in writing, through action taken by the
trustees, partners or other persons having authority to bind the trust, limited
partnership or other estate planning entity, to be bound by the restrictions set
forth in this Section 15.1, (III) any charitable organization that qualifies for
receipt of charitable contributions under Section 170(c) of the Code which
agrees with AmPaM in writing to be bound by the restrictions set forth in this
Section 15.1, (D) for transfers of AmPaM Stock or AmPaM Notes to AmPaM pursuant
to Section 11.5(d), (E) for transfers to another Stockholder, to another person
or entity who receives shares of AmPaM Stock or AmPaM Notes or AmPaM Series A
Preferred Stock pursuant to the Other Agreements or to Sterling City Capital LLC
or any of its Affiliates provided that (1) such transaction is exempt from the
registration requirements of the 1933 Act as evidenced by the delivery to AmPaM
of an opinion of counsel in form and substance reasonably satisfactory to AmPaM
and (2) any such transferee agrees in writing to be bound by the restrictions
set forth in this Section 15.1, (F) transfers of shares of AmPaM Notes, shares
of AmPaM Stock, or grants of options to purchase shares of AmPaM Stock, by such
Stockholder to employees of the Company of up to an aggregate of 15% of the
shares of AmPaM Stock received by such Stockholder pursuant to this Agreement
provided that (1) any such transaction is exempt from the registration
requirements of the 1933 Act as evidenced by the delivery to AmPaM of an opinion
of counsel in form and substance reasonably satisfactory to AmPaM and (2) any
such employee agrees with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1 or (G) the sale by such Stockholder in an IPO of
shares of AmPaM Stock representing not more than 10% of the Aggregate
Consideration in cash; provided,





                                       50
<PAGE>   59

however, that in no circumstance will a Stockholder be entitled to sell shares
of AmPaM Stock in an IPO to the extent that the sale of such shares by such
Stockholder would result in such Stockholder receiving in excess of 45% of the
Aggregate Consideration in cash; and, provided further, if AmPaM 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
Section 17.1 that the number of shares to be sold by persons other than AmPaM is
greater than the number of such shares which can be offered without adversely
affecting the success of the offering, AmPaM may reduce pro rata (among the
Stockholders and all other selling security holders in the offering) 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. During the Restricted Period, the certificates evidencing the AmPaM
Stock or AmPaM Notes delivered to the Stockholders pursuant to Section 3 of this
Agreement will bear a legend substantially in the form set forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION
OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the shares
of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to be
delivered to such 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 sold, assigned, exchanged, transferred, pledged or
otherwise disposed of without compliance with the 1933 Act which, among other
matters, would require registration under the 1933 Act unless exemption from the
registration requirements is available for such transaction. The AmPaM Stock,
the Additional Consideration Right and any AmPaM Notes to be acquired by each
Stockholder pursuant to this Agreement is being acquired solely for such
Stockholder's own account, for investment purposes only, and with no present
intention of selling, assigning, exchanging, transferring, pledging, or
otherwise disposing of it. Each Stockholder covenants, warrants and represents
that neither the shares of AmPaM Stock, the Additional Consideration Right nor
any AmPaM Notes issued to such Stockholder will be offered, sold, assigned,
exchanged, pledged, 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 certificates representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision), and
is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of the
nature described in the preceding sentence and all questions have been answered
to such Stockholder's satisfaction. Except as set forth on Schedule 16.2, each
Stockholder is an "accredited investor" as defined in Rule 501(a) of the 1933
Act. Neither the foregoing nor any investigation made by the Stockholders
referred to above shall in any way affect the representations, warranties,
covenants and agreements of AmPaM made herein except to the extent that AmPaM is
relying upon the representations of the Stockholders in Section 16.1 and in this
Section 16.2 for purposes of



                                       52
<PAGE>   61



AmPaM's representations and warranties in Sections 6.9, 6.11, 6.15 and 6.17
hereof as specified therein.

         16.3 RELIANCE BY AmPaM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to register
any AmPaM Stock for its own or other's 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 AmPaM and (ii)
registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other distribution with respect
to, or in exchange for, or in replacement of such AmPaM Stock) which any such
Stockholder requests, other than shares of AmPaM Stock which may then be
immediately sold under Rule 144(k) (or any similar or successor provision)
promulgated under the 1933 Act, and other than shares of AmPaM Stock that have
been theretofore sold by the Stockholder in accordance with the 1933 Act,
provided that AmPaM shall have the right to reduce pro rata the number of shares
of each selling Stockholder included in such registration to the extent that
inclusion of such shares would, in the written opinion of tax counsel to AmPaM
or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Private Placement Memorandum as a tax-free
organization under Section 351 of the Code; provided, however, that with respect
to a proposal by AmPaM to register AmPaM Stock under the 1933 Act in connection
with an IPO, no Stockholder shall be permitted pursuant to this Section 17.1 to
have included in such registration more shares of AmPaM Stock than permitted to
be sold by such Stockholder pursuant to Section 15.1. In addition, if AmPaM 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 AmPaM is greater than the number of such shares which can be offered
without adversely affecting the success of the offering, AmPaM may reduce pro
rata (among the Stockholders and all other selling security holders in the
offering) 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. If any Stockholder disapproves of the terms of the
underwriting, that Stockholder may elect to withdraw therefrom by written notice
to AmPaM and the managing underwriter. That Stockholder's shares of AmPaM Stock
so withdrawn shall also be withdrawn from registration; provided, however, that,
if by the withdrawal of such shares a greater number of shares of AmPaM



                                       53
<PAGE>   62



Stock held by other Stockholders may be included in such registration, then
AmPaM shall offer to all other Stockholders of AmPaM the right to include
additional shares in the same proportion used in effecting the above
limitations. AmPaM shall not, for a period of two years following the Closing
Date, grant to any other person any rights to cause AmPaM to register any
securities in priority over, or in precedent to, the rights granted to the
Stockholders hereunder and to the stockholders of the Other Founding Companies
pursuant to Section 17 of the Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a representative of the
         Stockholders with copies of all such documents proposed to be filed) as
         promptly as practical;

                  (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such registration statement or supplement to the prospectus;

                  (iv) 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;

                  (v) Make "generally available to its security holders" (within
         the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;




                                       54
<PAGE>   63



                  (vi) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of the registration statement at
         the earliest possible moment;

                  (vii) If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment such
         information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM Stock being sold by
         participating Stockholders to any underwriter or underwriters, the
         purchase price being paid therefor by such underwriter or underwriters
         and with respect to any other terms of an underwritten offering of the
         shares of AmPaM Stock to be sold in such offering, and promptly make
         all required filings of such prospectus by supplement or post-effective
         amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition pursuant
         to such registration statement, and the counsel retained by the
         participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or any
         such underwriter (collectively, the "Inspectors"), all financial and
         other records, pertinent corporate documents and properties of AmPaM
         (the "Records"), as shall be reasonably necessary to enable them to
         exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x) 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 required to
         be kept effective, provided that AmPaM shall not be required to become
         subject to taxation, to qualify generally to do business or to file a
         general consent to service of process in any such states or
         jurisdictions;

                  (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any



                                       55
<PAGE>   64



         securities exchanges or trading systems on which similar securities
         issued by AmPaM are then listed or included; and

                  (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in effect),
         together with any associated term sheet, contains an untrue statement
         of a material fact or omits to state any fact required to be stated
         therein or necessary to make the statements therein (in the case of the
         prospectus or any preliminary prospectus, in light of the circumstances
         under which they were made) not misleading, and, at the request of such
         Stockholder, AmPaM promptly 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 required to be
         stated therein or necessary to make the statements therein (in the case
         of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall be
borne by AmPaM.

         17.3 INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue statement
of material fact contained or incorporated by reference in any registration
statement, prospectus or preliminary prospectus or associated term sheet or any
omission or alleged omission to state or incorporated by reference therein a
material fact required to be stated or incorporated by reference 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 AmPaM 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 AmPaM has furnished
such Indemnified Party with a sufficient number of copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning of
the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged



                                       56
<PAGE>   65



untrue statement of a material fact or any omission or alleged omission to state
therein a material fact required to be stated in the registration statement or
prospectus or any amendment thereof or supplement thereto or necessary to make
the statements therein not misleading, but only to the extent that such untrue
or alleged untrue statement or omission or alleged omission is contained in or
omitted from information so furnished in writing to AmPaM by such Stockholder
expressly for use in 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 hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i) each
participating Stockholder shall execute and deliver to AmPaM a written power of
attorney instrument that (A) appoints an officer of AmPaM as such Stockholder's
attorney-in-fact for purposes of executing and delivering an underwriting
agreement among AmPaM, the underwriters named therein and such Stockholder
specifying the terms and conditions applicable to the sale of AmPaM Stock of
such Stockholder in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering in which
one or more stockholders of the issuer are participants, including a provision
that authorizes the attorney-in-fact appointed by such Stockholder to execute
and deliver such an underwriting agreement in the event that the net price per
share to be received by such Stockholder from the sale of the shares of AmPaM
Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters



                                       57
<PAGE>   66



specifically for inclusion in any such registration statement and (B) such
Stockholder shall not be obligated to enter into such an underwriting agreement
in the event that the net price per share to be received by such Stockholder
from the sale of shares of AmPaM Stock to be sold in such offering is less than
the floor price specified in the power of attorney instrument executed and
delivered to AmPaM pursuant to clause (i) above.

         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares of
AmPaM Stock under this Agreement may be assigned to a transferee or assignee of
any Stockholder to the extent that such transferee or assignee is a member of
the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

                  (i) make and keep public information regarding AmPaM available
         as those terms are understood and defined in Rule 144 under the 1933
         Act beginning 90 days following the effective date of a registration
         statement relating to an IPO;

                  (ii) file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 AmPaM, 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.      REDEMPTION OF AmPaM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal payments,
if any, made with respect to AmPaM Notes held by such Stockholder) equal to or
exceeding 50% of the Aggregate Consideration on or prior to the third
anniversary of the Closing Date, such Stockholder shall have the right (the "Put
Right"), but not the



                                       58
<PAGE>   67


obligation, commencing on the third anniversary of the Closing Date to require
AmPaM to purchase a number of shares of AmPaM Stock then owned by such
Stockholder, subject to the limitations set forth in Section 18.2 below. The
purchase price for such redemption shall be $13.00 per share, such price to be
subject to appropriate adjustment to reflect any reclassification, stock
dividend, subdivision, split-up or combination of shares of AmPaM Stock after
the date hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified, AmPaM
shall be obligated to purchase from each eligible Stockholder no less than 10%
of the AmPaM Stock held by such Stockholder annually; provided, however, that
the Stockholders shall not be entitled to exercise their Put Rights if and to
the extent the Company has not achieved the Target Net Income (as defined in
Annex I hereto) for the year preceding the year in which a Stockholder seeks to
exercise his Put Right. The redemptions will be funded by internal cash flows or
alternative financing arrangements but AmPaM's obligation to make any redemption
pursuant to this Section 18 will be subject to the covenants and restrictions
contained in AmPaM's then existing private or public debt or equity instruments.

         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right by
giving written notice (the "Put Notice") to AmPaM within thirty (30) days of the
third anniversary of the execution hereof. If any Stockholder does not provide
AmPaM with a Put Notice within such thirty-day period, the Put Right applicable
to such Stockholder shall expire. The date for closing the sale of any shares of
AmPaM Stock pursuant to a proper exercise of a Put Right shall in no event be
earlier than 90 days after the date AmPaM receives the Put Notice. Any such
closing shall be at such time of day and place as shall be mutually agreed
between such holder and AmPaM. At such closing AmPaM shall make payment for the
AmPaM Stock to be repurchased by wire transfer of immediately available funds to
a bank account designated by such Stockholder for such purpose and such
Stockholder shall deliver to AmPaM certificates, duly endorsed for transfer,
representing the shares of AmPaM Stock to be purchased and sold pursuant to the
exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger or
consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any,



                                       59
<PAGE>   68



which are then held by persons other than the holders of AmPaM Common Stock as
of the Closing Date constitute 50% or more of AmPaM Common Stock outstanding as
of the date of the consummation of such transaction.

19.      GENERAL

         19.1 COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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
AmPaM on and after the Closing 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 Closing Date.

         19.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the

benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

         19.3 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 and AmPaM 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 by
a written instrument executed by the Stockholders, the Company and AmPaM, 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.

         19.4 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. A telecopied
facsimile of an executed counterpart of this Agreement shall be sufficient to
evidence the binding agreement of each party to the terms hereof. However, each
party agrees to return to the other parties an original, duly executed
counterpart of this Agreement promptly after delivery of a telecopied facsimile
thereof.

with the laws of the State of Texas, excluding any conflicts of law, rule or
principle that might refer same to the laws of another jurisdiction.

         19.9 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations,
warranties, covenants and agreements of the parties made herein and at the time
of the Closing or in writing delivered pursuant to the provisions of this
Agreement shall survive the consummation of the transactions contemplated hereby

applicable with respect thereto, until the expiration of all applicable statute
of limitations periods.

         19.10 EXERCISE OF RIGHTS AND REMEDIES. Except as otherwise provided
herein, no delay of or omission in the exercise of any right, power or remedy
accruing to any party as a result of any breach or default by any other party
under this Agreement shall impair any such right, power or remedy, nor shall it
be construed as a waiver of or acquiescence in any such breach or default, or of
any similar breach or default occurring later; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
occurring before or after that waiver.

         19.11 TIME. Time is of the essence with respect to this Agreement.

         19.12 REFORMATION AND SEVERABILITY. In case any provision of this
Agreement shall be invalid, illegal or unenforceable, it shall, to the extent
possible, be modified in such manner as to be valid, legal and enforceable but
so as to most nearly retain the intent of the parties, and if such modification
is not possible, such provision shall be severed from this Agreement, and in
either case the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby. No provision of this Agreement shall be interpreted or construed
against any party solely because that party or its legal representative drafted
such provision.

         19.13 REMEDIES CUMULATIVE. No right, remedy or election given by any
term of this Agreement shall be deemed exclusive but each shall be cumulative
with all other rights, remedies and elections available at law or in equity.

amendment or waiver effected in accordance with this Section 19.15 shall be
binding upon each of the parties hereto, any other person receiving AmPaM Stock
in connection with the purchase and sale of the Company Stock and each future
holder of such AmPaM Stock. Any

<PAGE>   72



consent of the Stockholders who would receive a majority of the Aggregate
Consideration pursuant to Section I of Annex I of this Agreement if the
transactions contemplated hereby were consummated shall be deemed to be the
consent of the Stockholders for purposes of provisions of this Agreement as to
which a consent of the Stockholders may be requested or required.

         19.16 MEDIATION AND ARBITRATION. If a dispute arises out of or relates
to this Agreement, or the breach thereof, and if said dispute cannot be settled
through direct discussions, the parties agree to first endeavor to settle the
dispute in an amicable manner by mediation administered by the American
Arbitration Association under its then prevailing Commercial Mediation Rules,
before resorting to arbitration. Thereafter, any unresolved controversy or claim
arising out of or relating to this Agreement, or the breach thereof, shall be
settled by arbitration administered by the American Arbitration Association in
accordance with its then prevailing Commercial Arbitration Rules. The
enforcement, interpretation and procedural and substantive effect of the
obligation to arbitrate created by this Section 19.16 shall be governed by the
Federal Arbitration Act as amended from time to time, 9 U.S.C. Section 1 et seq.
The parties hereby disclaim any intention to have the substantive or procedural
law of any state or other jurisdiction, other than the law of the United States
as embodied in the Federal Arbitration Act, applied to such obligation. Any such
mediation or arbitration proceeding will be conducted in Houston, Texas.

Income Security Act of 1974, as amended ("ERISA")) or any non-qualified deferred
compensation arrangement). For the purposes of this Agreement, the term

administration thereof are in compliance in all material respects 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 as of the Balance
Sheet Date with respect to any plan listed on Schedule 5.19(a) have either been
fulfilled in their entirety or are fully reflected on the balance sheet of the
Company as of the Balance Sheet Date.

         5.20     COMPLIANCE WITH ERISA. All plans listed on Schedule 5.19(a)
that are intended to qualify under Section 401 (a) of the Code (the "Qualified
Plans") are, and have been so qualified and have been determined by the Internal
Revenue Service to be so qualified, and copies of such determination letters are
attached to Schedule 5.19(a). 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) since January 1, 1992 have been
timely filed or distributed, and copies thereof have been made available to
AmPaM. No such plan listed on Schedule 5.19(a) nor the Company has engaged in

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 Pension Benefit Guaranty Corporation. The Company further represents that

         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(a);

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

                  (v)   no circumstances exist pursuant to which the Company
         could 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.

reasonably be expected to have a Material Adverse Effect on the Company.

6.       REPRESENTATIONS OF AMPAM

         Except as otherwise qualified below, AmPaM represents and warrants that
all of the following representations and warranties in this Section 6 are true
at the date of this Agreement and, subject to Section 7.7 hereof, shall be true
at the time of Closing, and that such representations and warranties shall
survive the Closing Date for a period of eighteen months (the last day of such
period being the "Expiration Date" for purposes of the representations and
warranties set forth in this Section 6), except that the representations and
warranties set forth in Section 6.3, 6.11 and 6.15 shall survive until such time
as the applicable statute of limitations period has run, which shall be deemed
to be the Expiration Date for the representations and warranties set forth in
Sections 6.3, 6.11 and 6.15.

         AmPaM acknowledges that in purchasing the shares of Company Stock, it
is relying upon its own independent investigation as well as the representations
and warranties of the Company and the Stockholders as set forth in this
Agreement.

         6.1     DUE ORGANIZATION. AmPaM is a corporation duly incorporated and
organized, validly existing and in good standing under the laws of the State of
Delaware, and has the requisite power and authority to carry on its business as
it is now being conducted and as contemplated by the Private Placement
Memorandum. AmPaM is duly qualified or authorized to do business and is in good
standing in each jurisdiction in which the nature of its business or the
ownership or leasing of

                                       23

<PAGE>   32




its properties makes such qualification or authorization necessary, except where
the failure to be so qualified or authorized to do business would not have a
Material Adverse Effect. True, complete and correct copies of the Certificate of
Incorporation and By-laws, each as proposed to be amended and as such documents
shall be in effect as of the Closing Date, of AmPaM (the "AmPaM Charter
Documents") are attached hereto as Annex II.

         6.2     AUTHORIZATION. (i) The officers of AmPaM executing this
Agreement have the authority to enter into and bind AmPaM to the terms of this
Agreement and (ii) AmPaM has the full legal right, power and authority to enter
into this Agreement and consummate the transactions contemplated hereby. All
corporate acts and other proceedings required to have been taken by AmPaM to
authorize the execution, delivery and performance of this Agreement and the
consummation of the transactions contemplated hereby have been duly and properly
taken.

         6.3     CAPITAL STOCK OF AMPAM. The authorized capital stock of
AmPaM is as set forth in Section 1.3(ii). Immediately prior to the Closing Date,
all of the issued and outstanding shares of the capital stock of AmPaM will be
as set forth in the Private Placement Memorandum, free and clear of all liens,
security interests, pledges, charges, voting trusts, restrictions, encumbrances
and claims of every kind other than any restrictions described in the Private
Placement Memorandum. All of the issued and outstanding shares of the capital
stock of AmPaM have been duly authorized and validly issued, are fully paid and
nonassessable and such shares were offered, issued, sold and delivered by AmPaM
in compliance with all applicable state and Federal laws concerning the issuance
of securities. Further, none of such shares were issued in violation of the
preemptive rights of any past or present stockholder of AmPaM. Upon the Closing
Date, the authorized, issued and outstanding shares of capital stock of AmPaM
will be as set forth in the Private Placement Memorandum under the caption
"Capitalization." Upon the Closing Date, the aggregate number of shares of AmPaM
Stock issued and outstanding on the Closing Date that are owned by Sterling City
Capital, LLC, any Affiliates of Sterling City Capital, LLC and the officers and
directors of AmPaM will not be greater than the number of shares of AmPaM Stock
reflected in the Private Placement Memorandum as the aggregate number of shares
of AmPaM Stock to be issued and outstanding and owned by Sterling City Capital,
LLC, any Affiliates of Sterling City Capital, LLC and the officers and directors
of AmPaM.

         6.4     TRANSACTIONS IN CAPITAL STOCK. Except for the Other
Agreements and except as set forth in the Private Placement Memorandum, (i) no
option, warrant, call, conversion right or commitment of any kind exists as of
the date of this Agreement which obligates AmPaM to issue any of its authorized
but unissued capital stock; and (ii) AmPaM has no obligation (contingent or
otherwise) to purchase, redeem or otherwise acquire any of its equity securities
or any interests therein or to pay any dividend or make any distribution in
respect thereof. The material terms of any options, warrants or other rights to
acquire shares of the stock of AmPaM referred to in the preceding sentence will
be as described in the Private Placement Memorandum.

         6.5     SUBSIDIARIES. As of the date of this Agreement, AmPaM has no
subsidiaries. As of the date of this Agreement, AmPaM does not own, of record or
beneficially, or control, directly or indirectly, any capital stock, securities
convertible into capital stock or any other equity interest in any corporation,
association or business entity, and AmPaM is not, directly or indirectly, a
participant in any joint venture, partnership or other non-corporate entity.

AmPaM included in the Private Placement Memorandum (the "AmPaM Financial
Statements") have been prepared in accordance with GAAP applied on a consistent
basis throughout the periods indicated (except as noted thereon), and the
balance sheet included therein presents fairly the financial position of AmPaM
as of its date. Management of AmPaM believes that the assumptions underlying the
pro forma adjustments utilized in the preparation of such pro forma financial
statements are reasonable, and such pro forma adjustments have been properly
applied to the historical financial amounts in the compilation of the pro forma
financial statements. Based on the representations in Section 5.9 of this
Agreement and in Section 5.9 of each of the Other Agreements, the pro forma
financial information of AmPaM fairly presents the pro forma financial position,
results of operations and other information purported to be shown therein at the
respective dates and for the respective periods specified.

         6.7     LIABILITIES AND OBLIGATIONS. Except as set forth in the Private
Placement Memorandum, as of the date of this Agreement, AmPaM has no material
liabilities or obligations of any kind, character or description, whether
accrued, absolute, secured or unsecured, contingent or otherwise, other than
liabilities incurred in the ordinary course of business and consistent with past
practices, liabilities or obligations set forth in or contemplated by this
Agreement and the Other Agreements and except for fees incurred in connection
with the transactions contemplated hereby and thereby.

         6.8     CONFORMITY WITH LAW; LITIGATION. Except to the extent set
forth in the Private Placement Memorandum, AmPaM is not in violation of any law
or regulation or any order of any court or Federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality
having jurisdiction over it and its stockholders and, there are no claims,
actions, suits or proceedings, pending or, to the knowledge of AmPaM, threatened
against or affecting, AmPaM, at law or in equity, or before or by any Federal,
state, municipal or other governmental department, commission, board, bureau,
agency or instrumentality having jurisdiction over it and no notice of any
claim, action, suit or proceeding, whether pending or threatened, has been
received. AmPaM has conducted and is conducting its businesses in compliance in
all material respects with the requirements, standards, criteria and conditions
set forth in applicable Federal, state and local statutes, ordinances, permits,
licenses, orders, approvals, variances, rules and regulations and is not in
violation, in any material respect, of any of the foregoing.

         7.6      NOTIFICATION OF CERTAIN MATTERS. Each Stockholder and the
Company shall give prompt notice to AmPaM upon obtaining knowledge of (i) the

Stockholder or the Company to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by such person hereunder. AmPaM shall

provisions of Section 7.7, such notification shall not relieve either the
Company or such Stockholder of their respective obligations under this

deemed to (i) modify the representations or warranties hereunder of the party
delivering such notice, which modification may only be made pursuant to Section
7.7, (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

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 or (ii)

party. Notwithstanding the foregoing sentence, no amendment or supplement to a
Schedule prepared by the Company may be made unless AmPaM consents to such
amendment or supplement; and provided further, that no amendment or supplement
to a Schedule prepared by AmPaM may be made unless the Stockholders consent to

supplemented with the consent of AmPaM or the Stockholders, as the case may be,
as provided above, shall be deemed to be the Schedules to this Agreement.

         7.8      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

any breach of the representations and warranties of such Stockholder set forth
in Section 5(B) hereof, (ii) any breach of any covenant or agreement on the part
of such Stockholder under this Agreement, or (iii) any liability under the 1933
Act or any Federal or state securities 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 solely to such Stockholder which was based
upon information provided to AmPaM or its counsel in writing by such Stockholder
specifically for inclusion in the Private Placement Memorandum and is contained
in the Private Placement Memorandum, 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 solely to such Stockholder required to be
stated therein or necessary to make the statements therein in light of the
circumstances in which such statements were made not misleading.

         (c)      AmPaM acknowledges and agrees that other than the
representations and warranties of the Company or the Stockholders specifically
contained in this Agreement, there are no representations or warranties of the
Company or the Stockholders, either express or implied, with respect to the
transactions contemplated by this Agreement, the Company or its assets,
liabilities and business.

         11.2     INDEMNIFICATION BY AMPAM. AmPaM covenants and agrees that it
will indemnify, defend, protect and hold harmless the Company and the
Stockholders at all times from and after the date of this Agreement until the
applicable Expiration Date (as defined in the introductory paragraph of Section
6, provided that for purposes of clause (iii) below, the applicable 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 the Company or the Stockholders as a result of or arising from (i)
any breach by AmPaM of its representations and warranties set forth herein or on
the schedules attached



                                       41
<PAGE>   50



hereto or certificates delivered pursuant to this Agreement, (ii) any breach of
any agreement on the part of AmPaM under this Agreement; or (iii) any liability
under the 1933 Act or any Federal or state securities 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 contained in the Private Placement
Memorandum, 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
required to be stated therein or necessary to make the statements therein not
misleading, except to the extent such is based upon an untrue statement or
alleged untrue statement, or omission or alleged omission, made therein in
reliance upon, and in conformity with, the representations and warranties of the
Company or the Stockholders specifically contained in this Agreement or other
information furnished to AmPaM by the Company or the Stockholders in writing
specifically for inclusion therein.

         11.3      THIRD PERSON CLAIMS. Promptly after any party hereto
(hereinafter the "Indemnified Party") has received notice of or has knowledge of
any claim by a person not a party to this Agreement ("Third Person"), or the
commencement of any action or proceeding by a Third Person, 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 reasonably
satisfactory to the Indemnified Party, 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 or a conflict of
interest is reasonably likely to arise that prevents counsel for the
Indemnifying Party from representing such 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, 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


                                       42
<PAGE>   51




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. 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 pay the Indemnified Party
for the settlement amount 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. With respect to any account, note or other
receivable as to which the Stockholders have paid in full any indemnification
obligation pursuant to this Section 11 as a result of a breach of the
representation and warranty made pursuant to Section 5.11 or as to which a claim
in respect thereof has been asserted pursuant to this Section 11 that has been
applied against the Indemnification Threshold with respect to the Stockholders
as a result of a breach of the representation and warranty made pursuant to
Section 5.11, AmPaM shall cause the Company to assign such account, note or
other receivable to the Stockholders. 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. 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 to this Agreement with respect to any
provision of this Agreement, provided that, nothing herein shall be construed to
limit the right of a party, in a proper case, to seek injunctive relief for a
breach of this Agreement. AmPaM hereby waives, to the fullest extent permitted
under applicable law, any and all other rights, claims and causes of action,
known or unknown, it or any indemnified person may have against the Company or
any Stockholder relating to this Agreement or the transactions pursuant to this
Agreement arising under or based upon any Federal, state, local or foreign
statute, law, rule, regulation or otherwise. 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.

         11.5     LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2



                                       43
<PAGE>   52


plus (ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2 (calculated as provided in this Section 11.5) plus (iii) the
principal amount of the AmPaM Notes delivered to the Stockholders pursuant to
Section 1.2, or (b) $50,000 (the "Indemnification Threshold"). Stockholders
shall not assert any claim for indemnification hereunder against AmPaM until
such time as, and solely to the extent that, the aggregate of all claims which
Stockholders may have against AmPaM shall exceed $50,000; provided, however,
that this sentence shall not be applicable with respect of any failure by AmPaM
to (i) deliver the consideration specified in Annex I hereto on the Closing Date
upon the satisfaction, or waiver by AmPaM, of all conditions to the occurrence
of the Closing Date specified in Section 9 or (ii) comply with its obligations
pursuant to Section 10.1. After the $50,000 threshold for AmPaM (subject to the
proviso in the preceding sentence) or the Indemnification Threshold for a
Stockholder has been met, all claims must be made in $10,000 increments, which
claims may be cumulated in order to meet such $10,000 thresholds. For purposes
of this paragraph, the AmPaM Stock delivered to the Stockholders shall be valued
at $13.00 per share.

         (b)      No person shall be entitled to indemnification under this
Section 11 if and to the extent that such person's claim for indemnification is
directly or indirectly related to a breach by such person of any representation,
warranty, covenant or other agreement set forth in this Agreement. No claim for
indemnification against the Stockholders shall limit, diminish or change any
obligation of AmPaM pursuant to Section 10.1 hereof.

         (c)      Notwithstanding any other term of this Agreement, no
Stockholder shall be liable under this Section 11 for an amount which exceeds
eighty-five percent (85%) of the amount of proceeds received by such Stockholder
(valued as of the Closing Date) in connection with the purchase and sale of the
Company Stock. For purposes of this paragraph, the AmPaM Stock shall be valued
at $13.00 per share.

         (d)      A Stockholder may pay any indemnification obligation under
Section 11 by means of the payment of cash or a combination of the payment of
cash, the forgiveness of amounts owed pursuant to the AmPaM Notes and the
delivery to AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of AmPaM
Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration paid to such Stockholder by AmPaM to such Stockholder pursuant to
Annex I. For the purpose of crediting Stockholders for payments made to AmPaM by
means of delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued at
$13.00 per share.

         (e)      In determining the amount of any loss, liability or expense
for which any party is entitled to indemnification under this Agreement, the
gross amount thereof will be reduced by any correlative insurance proceeds or
other third party indemnity or reimbursement proceeds realized or to be realized
by such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary
of AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM



                                       44
<PAGE>   53


shall use commercially reasonable efforts to pursue any available insurance
coverage or other rights of indemnity or reimbursement from third parties with
respect to any such loss, liability or expense.

12.      TERMINATION OF AGREEMENT

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

                  (i)    by mutual consent of AmPaM and the Stockholders;

                  (ii)   by the Stockholders, if the transactions contemplated
         by this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by the Company
         or the Stockholders prior to or on the Closing Date;

                  (iii)  by AmPaM, if the transactions contemplated by this
         Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by AmPaM prior
         to or on the Closing Date;

                  (iv)   by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein
         relating to AmPaM, and the curing of such default shall not have been
         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v)   by AmPaM, if a material breach or default shall be made
         by the Company or the Stockholders in the observance or in the due and
         timely performance of any of the covenants or agreements contained
         herein relating to the Company or the Stockholders, and the curing of
         such default shall not have been made (or in the reasonable judgment of
         AmPaM cannot be made) on or before the Closing Date;

                  (vi)   by the Stockholders, if the conditions set forth in
         Section 8 hereof have not been satisfied or waived as of the Closing
         Date; or

                  (vii)   by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2     PROCEDURE AND EFFECT OF TERMINATION. A determination to
terminate this Agreement by AmPaM pursuant to Section 12.1 shall be valid and
effective only if a written notice of termination, accompanied by a certified
copy of resolutions of the board of directors of AmPaM that evidence the
authorization of the officer of AmPaM to deliver a written notice of termination
of this Agreement pursuant to Section 12.1, is given to the Stockholders in the
manner specified for notices


                                       45
<PAGE>   54

in this Agreement. A determination to terminate this Agreement by the
Stockholders pursuant to Section 12.1 shall be valid and effective only if a
written notice of termination, signed by Stockholders who would be entitled to
receive a majority of the shares of AmPaM Stock specified in Section I of Annex
I to this Agreement if the transactions contemplated hereby were consummated, is
given to AmPaM in the manner specified for notices in this Agreement. Upon the
giving of notice of termination of this Agreement pursuant to Section 12.1 as
specified in the preceding sentence, this Agreement shall terminate, and the
transactions contemplated hereby shall be abandoned, without further action by
any of the parties hereto. Immediately upon any such termination, AmPaM shall
deliver written notice of such termination to the Other Founding Companies. If
this Agreement is terminated as provided in this Section 12, no party hereto
shall have any liability or further obligation hereunder to any other party,
except as provided in Section 14 and Section 18.6, provided, that, 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 that occurred prior to such termination.

13.      NONCOMPETITION

         13.1     PROHIBITED ACTIVITIES. The Stockholders will not, without the
prior written consent of AmPaM, for a period of two (2) years following the
Closing 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)    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, whether paid or unpaid, in any plumbing, piping,
         mechanical, heating, ventilation or air conditioning contracting,
         installation or services business or operation, whether for
         residential, commercial, industrial or governmental customers, or any
         ancillary contracting, installation or services business directly
         related thereto (such business and operations referred to herein as the
         "Plumbing and Mechanical Business"), within 100 miles of where the
         Company or any of its subsidiaries conducted business within two (2)
         years prior to the Closing Date (the "Territory");

                  (ii)   call upon any person who is, at the Closing Date,
         within the Territory, an employee of AmPaM or any subsidiary thereof
         for the purpose or with the intent of enticing such employee away from
         or out of the employ of AmPaM or any subsidiary thereof;

                  (iii)  call upon any person or entity which is, at the Closing
         Date, or which has been within three (3) years prior to the Closing
         Date, a customer of AmPaM or any subsidiary thereof, of the Company or
         of any of the Other Founding Companies for the purpose of soliciting
         customers, orders or contracts for any Plumbing and Mechanical Business
         in direct competition with AmPaM within the Territory;


                                       46
<PAGE>   55



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

                  (v)    disclose to any person, firm, partnership, corporation
         or business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or any
         of its subsidiaries within the two (2) years prior to the Closing Date
         for any reason or purpose whatsoever except to the extent that the
         Company has in the past disclosed such information to the public for
         valid business reasons; or

                  (vi)   testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

         13.2     DAMAGES. Because of the difficulty of measuring economic
losses to AmPaM as a result of a breach of the foregoing covenant, and because
of the immediate and irreparable damage that could be caused to AmPaM for which
it would have no other adequate remedy, each Stockholder agrees that the
foregoing covenant may be enforced by AmPaM 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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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.



                                       47
<PAGE>   56




         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by AmPaM of such
covenants. It is specifically agreed that the period of two (2) 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
found to be in violation of any provision of this Section 13 as determined by
any of (i) a written agreement to such effect executed and delivered by AmPaM
and such Stockholder, (ii) a determination by an arbitration panel pursuant to
an arbitration conducted pursuant to Section 18.16 hereof or (iii) a
non-appealable judgment of a court of competent jurisdiction. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto. The covenants contained in Section 13
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 the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and
pricing and cost policies that are valuable, special and unique assets of the
Company's, the Other Founding Companies' and/or AmPaM'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 AmPaM, (b)
following the Closing, such information may be disclosed by the Stockholders as
is required in the course of performing their duties for AmPaM or the Company
and (c) to its counsel and other advisers, provided that such advisers (other
than counsel) agree to the confidentiality provisions of this Section 14.1;
provided, however that (i) the foregoing disclosure prohibition shall not apply
in the event that (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 AmPaM and provide AmPaM 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,
AmPaM 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 AmPaM from pursuing any other available remedy
for such breach or threatened breach, including the recovery of damages. In the
event the transactions contemplated


                                       48
<PAGE>   57

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     AmPaM. AmPaM recognizes and acknowledges that it had in the
past and currently has access to certain confidential information of the
Company, such as operational policies, customer lists, and pricing and cost
policies that are valuable, special and unique assets of the Company's business.
AmPaM agrees that, prior to the Closing, or if the transactions contemplated by
this Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes known
to the public generally through no fault of AmPaM, (B) 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 (B), AmPaM
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 (C) 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 AmPaM of
the provisions of this Section 14.2, the Company and the Stockholders shall be
entitled to an injunction restraining AmPaM 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.
In the event the transactions contemplated by this Agreement are not consummated
for any reason, AmPaM shall nevertheless remain subject to this Section 14.2,
except that it shall not be permitted to make any disclosures otherwise than
pursuant to clause (A), (B) or (C) above.

         14.3     DAMAGES. Because of the difficulty of measuring economic
losses as a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the
covenant may be enforced against the other parties by injunctions and
restraining orders.

         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 Closing Date.

         15.1     TRANSFER RESTRICTIONS RELATING TO AmPaM STOCK AND AmPaM NOTES.

economic consequence of ownership of the AmPaM Stock or AmPaM Notes, whether any
such swap or transaction is to be settled by delivery of shares of AmPaM Stock
or AmPaM Notes or other securities, by the delivery or payment of cash or
otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A) as
otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock, pursuant
to Section 17 hereof, (C) for transfers to (I) immediate family members of such
Stockholder who agree with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1, (II) trusts, limited partnerships or other estate
planning entities for the benefit of such Stockholder or family members of such
Stockholder which have agreed with AmPaM in writing, through action taken by the

to Section 11.5(d), (E) for transfers to another Stockholder, to another person
or entity who receives shares of AmPaM Stock or AmPaM Notes or AmPaM Series A
Preferred Stock pursuant to the Other Agreements or to Sterling City Capital LLC
or any of its Affiliates provided that (1) such transaction is exempt from the
registration requirements of the 1933 Act as evidenced by the delivery to AmPaM
of an opinion of counsel in form and substance reasonably satisfactory to AmPaM
and (2) any such transferee agrees in writing to be bound by the restrictions
set forth in this Section 15.1, (F) transfers of shares of AmPaM Notes, shares
of AmPaM Stock, or grants of options to purchase shares of AmPaM Stock, by such
Stockholder to employees of the Company of up to an aggregate of 15% of the
shares of AmPaM Stock received by such Stockholder pursuant to this Agreement
provided that (1) any such transaction is exempt from the registration
requirements of the 1933 Act as evidenced by the delivery to AmPaM of an opinion
of counsel in form and substance reasonably satisfactory to AmPaM and (2) any
such employee agrees with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1 or (G) the sale by such Stockholder in an IPO of

Consideration in cash; provided,


                                       50
<PAGE>   59


however, that in no circumstance will a Stockholder be entitled to sell shares
of AmPaM Stock in an IPO to the extent that the sale of such shares by such
Stockholder would result in such Stockholder receiving in excess of 45% of the
Aggregate Consideration in cash; and, provided further, if AmPaM 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
Section 17.1 that the number of shares to be sold by persons other than AmPaM is
greater than the number of such shares which can be offered without adversely
affecting the success of the offering, AmPaM may reduce pro rata (among the
Stockholders and all other selling security holders in the offering) 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. During the Restricted Period, the certificates evidencing the AmPaM
Stock or AmPaM Notes delivered to the Stockholders pursuant to Section 3 of this
Agreement will bear a legend substantially in the form set forth below:

THE [SHARES/NOTES] OR AMPAM NOTES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
SOLD, ASSIGNED, EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT
PURSUANT TO THE TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES
WERE ISSUED, AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY
ATTEMPTED SALE, ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION
PRIOR TO EXPIRATION OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION
AGREEMENT EXCEPT IN ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH
RESTRICTIONS ON TRANSFER ARE SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF
WHICH IS MAINTAINED AT THE PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2     TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1     COMPLIANCE WITH LAW. Each Stockholder acknowledges that the
shares of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to
be delivered to such 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 sold, assigned, exchanged, transferred, pledged
or otherwise disposed of without compliance with the 1933 Act which, among other
matters, would require registration under the 1933 Act unless exemption from the
registration requirements is available for such transaction. The AmPaM Stock,
the Additional Consideration Right and any AmPaM Notes to be acquired by each
Stockholder pursuant to this Agreement is being acquired solely for such
Stockholder's own account, for investment purposes only, and with no present
intention of selling, assigning, exchanging, transferring, pledging, or
otherwise disposing of it. Each Stockholder covenants, warrants and represents
that neither the shares of AmPaM Stock, the Additional Consideration Right nor
any AmPaM Notes issued to such Stockholder will be offered, sold, assigned,
exchanged, pledged, 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 certificates representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2     ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to
bear the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision), and
is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of the
nature described in the preceding sentence and all questions have been answered
to such Stockholder's satisfaction. Except as set forth on Schedule 16.2, each
Stockholder is an "accredited investor" as defined in Rule 501(a) of the 1933
Act. Neither the foregoing nor any investigation made by the Stockholders
referred to above shall in any way affect the representations, warranties,
covenants and agreements of AmPaM made herein except to the extent that AmPaM is
relying upon the representations of the Stockholders in Section 16.1 and in this
Section 16.2 for purposes of


                                       52
<PAGE>   61

AmPaM's representations and warranties in Sections 6.9, 6.11, 6.15 and 6.17
hereof as specified therein.

         16.3     RELIANCE BY AmPaM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1     PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to
register any AmPaM Stock for its own or other's 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 AmPaM and
(ii) registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other distribution with respect
to, or in exchange for, or in replacement of such AmPaM Stock) which any such
Stockholder requests, other than shares of AmPaM Stock which may then be
immediately sold under Rule 144(k) (or any similar or successor provision)
promulgated under the 1933 Act, and other than shares of AmPaM Stock that have
been theretofore sold by the Stockholder in accordance with the 1933 Act,
provided that AmPaM shall have the right to reduce pro rata the number of shares
of each selling Stockholder included in such registration to the extent that
inclusion of such shares would, in the written opinion of tax counsel to AmPaM
or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Private Placement Memorandum as a tax-free
organization under Section 351 of the Code; provided, however, that with respect
to a proposal by AmPaM to register AmPaM Stock under the 1933 Act in connection
with an IPO, no Stockholder shall be permitted pursuant to this Section 17.1 to
have included in such registration more shares of AmPaM Stock than permitted to
be sold by such Stockholder pursuant to Section 15.1. In addition, if AmPaM 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 AmPaM is greater than the number of such shares which can be offered
without adversely affecting the success of the offering, AmPaM may reduce pro
rata (among the Stockholders and all other selling security holders in the
offering) 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. If any Stockholder disapproves of the terms of the
underwriting, that Stockholder may elect to withdraw therefrom by written notice
to AmPaM and the managing underwriter. That Stockholder's shares of AmPaM Stock
so withdrawn shall also be withdrawn from registration; provided, however, that,
if by the withdrawal of such shares a greater number of shares of AmPaM



                                       53
<PAGE>   62


Stock held by other Stockholders may be included in such registration, then
AmPaM shall offer to all other Stockholders of AmPaM the right to include
additional shares in the same proportion used in effecting the above
limitations. AmPaM shall not, for a period of two years following the Closing
Date, grant to any other person any rights to cause AmPaM to register any
securities in priority over, or in precedent to, the rights granted to the
Stockholders hereunder and to the stockholders of the Other Founding Companies
pursuant to Section 17 of the Other Agreements.

         17.2     REGISTRATION PROCEDURES. Whenever AmPaM is required to
register shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a representative of the
         Stockholders with copies of all such documents proposed to be filed) as
         promptly as practical;

                  (ii)   Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii)  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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such registration statement or supplement to the prospectus;

                  (iv)   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;

                  (v)    Make "generally available to its security holders"
         (within the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;


                                       54
<PAGE>   63

                  (vi)   Make every reasonable effort to obtain the withdrawal
         of any order suspending the effectiveness of the registration statement
         at the earliest possible moment;

                  (vii)  If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment such
         information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM Stock being sold by
         participating Stockholders to any underwriter or underwriters, the
         purchase price being paid therefor by such underwriter or underwriters
         and with respect to any other terms of an underwritten offering of the
         shares of AmPaM Stock to be sold in such offering, and promptly make
         all required filings of such prospectus by supplement or post-effective
         amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition pursuant
         to such registration statement, and the counsel retained by the
         participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or any
         such underwriter (collectively, the "Inspectors"), all financial and
         other records, pertinent corporate documents and properties of AmPaM
         (the "Records"), as shall be reasonably necessary to enable them to
         exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix)   Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x)    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 required to be kept effective, provided that AmPaM shall
         not be required to become subject to taxation, to qualify generally to
         do business or to file a general consent to service of process in any
         such states or jurisdictions;

                  (xi)   Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any


                                       55
<PAGE>   64

         securities exchanges or trading systems on which similar securities
         issued by AmPaM are then listed or included; and

                  (xii)  Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in effect),
         together with any associated term sheet, contains an untrue statement
         of a material fact or omits to state any fact required to be stated
         therein or necessary to make the statements therein (in the case of the
         prospectus or any preliminary prospectus, in light of the circumstances
         under which they were made) not misleading, and, at the request of such
         Stockholder, AmPaM promptly 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 required to be
         stated therein or necessary to make the statements therein (in the case
         of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall be
borne by AmPaM.

         17.3     INDEMNIFICATION.

                  (a)    In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue statement
of material fact contained or incorporated by reference in any registration
statement, prospectus or preliminary prospectus or associated term sheet or any
omission or alleged omission to state or incorporated by reference therein a
material fact required to be stated or incorporated by reference 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 AmPaM 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 AmPaM has furnished
such Indemnified Party with a sufficient number of copies of the same.

                  (b)    In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning of
the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged

                                       56
<PAGE>   65

untrue statement of a material fact or any omission or alleged omission to state
therein a material fact required to be stated in the registration statement or
prospectus or any amendment thereof or supplement thereto or necessary to make
the statements therein not misleading, but only to the extent that such untrue
or alleged untrue statement or omission or alleged omission is contained in or
omitted from information so furnished in writing to AmPaM by such Stockholder
expressly for use in 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 hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i) each
participating Stockholder shall execute and deliver to AmPaM a written power of
attorney instrument that (A) appoints an officer of AmPaM as such Stockholder's
attorney-in-fact for purposes of executing and delivering an underwriting
agreement among AmPaM, the underwriters named therein and such Stockholder
specifying the terms and conditions applicable to the sale of AmPaM Stock of
such Stockholder in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering in which
one or more stockholders of the issuer are participants, including a provision
that authorizes the attorney-in-fact appointed by such Stockholder to execute
and deliver such an underwriting agreement in the event that the net price per
share to be received by such Stockholder from the sale of the shares of AmPaM
Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters

                                       57
<PAGE>   66

specifically for inclusion in any such registration statement and (B) such
Stockholder shall not be obligated to enter into such an underwriting agreement
in the event that the net price per share to be received by such Stockholder
from the sale of shares of AmPaM Stock to be sold in such offering is less than
the floor price specified in the power of attorney instrument executed and
delivered to AmPaM pursuant to clause (i) above.

         17.5    TRANSFER OF RIGHTS. The right to cause AmPaM to register
shares of AmPaM Stock under this Agreement may be assigned to a transferee or
assignee of any Stockholder to the extent that such transferee or assignee is a
member of the immediate family of a Stockholder, a trust, limited partnership or
other estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6     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
AmPaM stock to the public without registration, following an IPO AmPaM agrees to
use its reasonable efforts, from and after the completion of an IPO, to:

                  (i)    make and keep public information regarding AmPaM
         available as those terms are understood and defined in Rule 144 under
         the 1933 Act beginning 90 days following the effective date of a
         registration statement relating to an IPO;

                  (ii)   file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 AmPaM, 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.      REDEMPTION OF AMPAM STOCK

         18.1     REDEMPTION TRIGGER. In the event that, within three years of
the Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder
has not received cash (including proceeds from the public or private sale of
AmPaM Stock received as consideration hereunder and the receipt of principal
payments, if any, made with respect to AmPaM Notes held by such Stockholder)
equal to or exceeding 50% of the Aggregate Consideration on or prior to the
third anniversary of the Closing Date, such Stockholder shall have the right
(the "Put Right"), but not the

                                       58
<PAGE>   67

obligation, commencing on the third anniversary date of the Closing Date to
require AmPaM to purchase a number of shares of AmPaM Stock then owned by such
Stockholder, subject to the limitations set forth in Section 18.2 below. The
purchase price for such redemption shall be $13.00 per share, such price to be
subject to appropriate adjustment to reflect any reclassification, stock
dividend, subdivision, split-up or combination of shares of AmPaM Stock after
the date hereof.

         18.2     MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified, AmPaM
shall be obligated to purchase from each eligible Stockholder no less than 10%
of the AmPaM Stock held by such Stockholder annually; provided, however, that
the Stockholders shall not be entitled to exercise their Put Rights if and to
the extent the Company has not achieved the Target Net Income (as defined in
Annex I hereto) for the year preceding the year in which a Stockholder seeks to
exercise his Put Right. The redemptions will be funded by internal cash flows or
alternative financing arrangements but AmPaM's obligation to make any redemption
pursuant to this Section 18 will be subject to the covenants and restrictions
contained in AmPaM's then existing private or public debt or equity instruments.

         18.3     NOTICE; EXERCISE. The Stockholders may exercise their Put
Right by giving written notice (the "Put Notice") to AmPaM within thirty (30)
days of the third anniversary of the execution hereof. If any Stockholder does
not provide AmPaM with a Put Notice within such thirty-day period, the Put Right
applicable to such Stockholder shall expire. The date for closing the sale of
any shares of AmPaM Stock pursuant to a proper exercise of a Put Right shall in
no event be earlier than 90 days after the date AmPaM receives the Put Notice.
Any such closing shall be at such time of day and place as shall be mutually
agreed between such holder and AmPaM. At such closing AmPaM shall make payment
for the AmPaM Stock to be repurchased by wire transfer of immediately available
funds to a bank account designated by such Stockholder for such purpose and such
Stockholder shall deliver to AmPaM certificates, duly endorsed for transfer,
representing the shares of AmPaM Stock to be purchased and sold pursuant to the
exercise of such Put Right.

         18.4     ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated
an IPO and notwithstanding the foregoing, to the extent the Stockholders who
have received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5     TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect
to any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger or
consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any,

                                       59
<PAGE>   68

which are then held by persons other than the holders of AmPaM Common Stock as
of the Closing Date constitute 50% or more of AmPaM Common Stock outstanding as
of the date of the consummation of such transaction.

19.      GENERAL

         19.1     COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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
AmPaM on and after the Closing 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 Closing Date.

         19.2     SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law and except as
provided in Section 17.5) and shall be binding upon and shall inure to the
benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

         19.3     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 and AmPaM 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 by
a written instrument executed by the Stockholders, the Company and AmPaM, 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.

         19.4     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. A
telecopied facsimile of an executed counterpart of this Agreement shall be
sufficient to evidence the binding agreement of each party to the terms hereof.
However, each party agrees to return to the other parties an original, duly
executed counterpart of this Agreement promptly after delivery of a telecopied
facsimile thereof.

receipt of the consideration payable pursuant to Section 1 hereof. The

include Tax risks, with respect to which the Stockholders are relying
substantially on the opinion contemplated by Section 8.12 hereof and

holder of such AmPaM Stock. Any consent of the Stockholders who would receive a
majority of the Aggregate Consideration pursuant to Section I of Annex I of this

         AmPaM acknowledges that in purchasing the shares of Company Stock, it
is relying upon its own independent investigation as well as the representations

         6.1 DUE ORGANIZATION. AmPaM is a corporation duly incorporated and
organized, validly existing and in good standing under the laws of the State of
Delaware, and has the requisite power and authority to carry on its business as
it is now being conducted and as contemplated by the Private Placement
Memorandum. AmPaM is duly qualified or authorized to do business and is in good
standing in each jurisdiction in which the nature of its business or the
ownership or leasing of


                                       23

<PAGE>   32



its properties makes such qualification or authorization necessary, except where
the failure to be so qualified or authorized to do business would not have a
Material Adverse Effect. True, complete and correct copies of the Certificate of
Incorporation and By-laws, each as proposed to be amended and as such documents
shall be in effect as of the Closing Date, of AmPaM (the "AmPaM Charter
Documents") are attached hereto as Annex II.

         6.2 AUTHORIZATION. (i) The officers of AmPaM executing this Agreement
have the authority to enter into and bind AmPaM to the terms of this Agreement
and (ii) AmPaM has the full legal right, power and authority to enter into this
Agreement and consummate the transactions contemplated hereby. All corporate
acts and other proceedings required to have been taken by AmPaM to authorize the
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby have been duly and properly taken.

         6.3 CAPITAL STOCK OF AmPaM. The authorized capital stock of AmPaM is as
set forth in Section 1.3(ii). Immediately prior to the Closing Date, all of the
issued and outstanding shares of the capital stock of AmPaM will be as set forth
in the Private Placement Memorandum, free and clear of all liens, security
interests, pledges, charges, voting trusts, restrictions, encumbrances and
claims of every kind other than any restrictions described in the Private
Placement Memorandum. All of the issued and outstanding shares of the capital
stock of AmPaM have been duly authorized and validly issued, are fully paid and
nonassessable and such shares were offered, issued, sold and delivered by AmPaM
in compliance with all applicable state and Federal laws concerning the issuance
of securities. Further, none of such shares were issued in violation of the
preemptive rights of any past or present stockholder of AmPaM. Upon the Closing
Date, the authorized, issued and outstanding shares of capital stock of AmPaM
will be as set forth in the Private Placement Memorandum under the caption
"Capitalization." Upon the Closing Date, the aggregate number of shares of AmPaM
Stock issued and outstanding on the Closing Date that are owned by Sterling City
Capital, LLC, any Affiliates of Sterling City Capital, LLC and the officers and
directors of AmPaM will not be greater than the number of shares of AmPaM Stock
reflected in the Private Placement Memorandum as the aggregate number of shares
of AmPaM Stock to be issued and outstanding and owned by Sterling City Capital,
LLC, any Affiliates of Sterling City Capital, LLC and the officers and directors
of AmPaM.

         6.4 TRANSACTIONS IN CAPITAL STOCK. Except for the Other Agreements and
except as set forth in the Private Placement Memorandum, (i) no option, warrant,
call, conversion right or commitment of any kind exists as of the date of this
Agreement which obligates AmPaM to issue any of its authorized but unissued
capital stock; and (ii) AmPaM has no obligation (contingent or otherwise) to
purchase, redeem or otherwise acquire any of its equity securities or any
interests therein or to pay any dividend or make any distribution in respect
thereof. The material terms of any options, warrants or other rights to acquire
shares of the stock of AmPaM referred to in the preceding sentence will be as
described in the Private Placement Memorandum.

subsidiaries. As of the date of this Agreement, AmPaM does not own, of record or

convertible into capital stock or any other equity interest in any corporation,
association or business entity, and AmPaM is not, directly or indirectly, a

included in the Private Placement Memorandum (the "AmPaM Financial Statements")
have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods indicated (except as noted thereon), and the balance
sheet included therein presents fairly the financial position of AmPaM as of its
date. Management of AmPaM believes that the assumptions underlying the pro forma
adjustments utilized in the preparation of such pro forma financial statements
are reasonable, and such pro forma adjustments have been properly applied to the
historical financial amounts in the compilation of the pro forma financial
statements. Based on the representations in Section 5.9 of this Agreement and in

of AmPaM fairly presents the pro forma financial position, results of operations
and other information purported to be shown therein at the respective dates and
for the respective periods specified.

Placement Memorandum, as of the date of this Agreement, AmPaM has no material
liabilities or obligations of any kind, character or description, whether
accrued, absolute, secured or unsecured, contingent or otherwise, other than
liabilities incurred in the ordinary course of business and consistent with past
practices, liabilities or obligations set forth in or contemplated by this
Agreement and the Other Agreements and except for fees incurred in connection
with the transactions contemplated hereby and thereby.

         6.8 CONFORMITY WITH LAW; LITIGATION. Except to the extent set forth in

regulation or any order of any court or Federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality
having jurisdiction over it and its stockholders and, there are no claims,
actions, suits or proceedings, pending or, to the knowledge of AmPaM, threatened
against or affecting, AmPaM, at law or in equity, or before or by any Federal,
state, municipal or other governmental department, commission, board, bureau,
agency or instrumentality having jurisdiction over it and no notice of any
claim, action, suit or proceeding, whether pending or threatened, has been
received. AmPaM has conducted and is conducting its businesses in compliance in
all material respects with the requirements, standards, criteria and conditions
set forth in applicable Federal, state and local statutes, ordinances, permits,
licenses, orders, approvals, variances, rules and regulations and is not in
violation, in any material respect, of any of the foregoing.

Company consummates an IPO, the persons who will serve as directors and
executive officers of AmPaM will be adjusted as appropriate for a publicly
traded entity, with any such changes being subject to the approval of the
majority of the Board of Directors of AmPaM.

         10.5 LEGAL OPINIONS. If required by the lenders pursuant to the terms
of any agreements related to financing of the cash amounts referred to in
Section 9.11 hereof, the Company shall cause its counsel to deliver to such
lenders, at the Closing, an opinion of counsel in substantially the form
attached hereto as Annex V.

11.      INDEMNIFICATION

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

         11.1 GENERAL INDEMNIFICATION BY THE STOCKHOLDERS.

         (a) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement until the applicable Expiration Date (as defined in
the introductory paragraph to Section 5(A)), provided that for purposes of
clause (iii) below, the applicable 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 AmPaM as a result of
or arising from (i) any breach of the representations and warranties of the
Company set forth herein or on the schedules attached hereto or certificates
delivered pursuant to this Agreement, (ii) any breach of any covenant or
agreement on the part of the Company under this Agreement, or (iii) any
liability under the 1933 Act or any Federal or state securities law or

statement or alleged untrue statement of a material fact relating solely to the
Company which was based upon information provided to AmPaM or its counsel in
writing by the Company specifically for inclusion in the Private Placement
Memorandum and is contained in the Private Placement Memorandum, 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 required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that no Stockholder shall be liable
for any


                                       40
<PAGE>   49


indemnification obligation pursuant to this Section 11.1 in excess of such
Stockholder's pro rata share thereof determined by reference to the aggregate
value of the Base Cash Amount (as defined in Annex I of this Agreement), the
principal amount of AmPaM Notes and the shares of AmPaM Stock (valued at a price
of $13.00 per share) received by such Stockholder pursuant to Section I.A. of
Annex I hereto (without giving effect to the adjustments provided in Sections
I.B. and I.C. thereof) (giving effect to the value of such AmPaM Stock and
without giving effect to such adjustments, collectively, the "Aggregate
Consideration") such Stockholder would receive pursuant to Section I of Annex I
of this Agreement if the transactions contemplated hereby were consummated in
relation to the total Aggregate Consideration all Stockholders would receive
pursuant to Section I of Annex I of this Agreement if the transactions
contemplated hereby were consummated.

         (b) Each Stockholder covenants and agrees that such Stockholder will
indemnify, defend, protect and hold harmless AmPaM at all times, from and after
the date of this Agreement, 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 AmPaM as a result of or arising from (i)
any breach of the representations and warranties of such Stockholder set forth
in Section 5(B) hereof, (ii) any breach of any covenant or agreement on the part
of such Stockholder under this Agreement, (iii) the guarantees of the Company
listed on Schedule 5.10 or (iv) any liability under the 1933 Act or any Federal
or state securities 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 solely to such Stockholder which was based upon information
provided to AmPaM or its counsel in writing by such Stockholder specifically for
inclusion in the Private Placement Memorandum and is contained in the Private
Placement Memorandum, 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 solely to such Stockholder required to be stated therein
or necessary to make the statements therein in light of the circumstances in
which such statements were made not misleading.

         (c) AmPaM acknowledges and agrees that other than the representations
and warranties of the Company or the Stockholders specifically contained in this
Agreement, there are no representations or warranties of the Company or the
Stockholders, either express or implied, with respect to the transactions
contemplated by this Agreement, the Company or its assets, liabilities and
business.

         11.2 INDEMNIFICATION BY AmPaM. AmPaM covenants and agrees that it will
indemnify, defend, protect and hold harmless the Company and the Stockholders at
all times from and after the date of this Agreement until the applicable
Expiration Date (as defined in the introductory paragraph of Section 6, provided
that for purposes of clause (iii) below, the applicable 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 the
Company or the Stockholders as a result of or arising from (i) any breach by
AmPaM of its representations and warranties set forth herein or on the schedules
attached


                                       41
<PAGE>   50


hereto or certificates delivered pursuant to this Agreement, (ii) any breach of
any agreement on the part of AmPaM under this Agreement; or (iii) any liability
under the 1933 Act or any Federal or state securities 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 contained in the Private Placement
Memorandum, 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
required to be stated therein or necessary to make the statements therein not
misleading, except to the extent such is based upon an untrue statement or
alleged untrue statement, or omission or alleged omission, made therein in
reliance upon, and in conformity with, the representations and warranties of the
Company or the Stockholders specifically contained in this Agreement or other
information furnished to AmPaM by the Company or the Stockholders in writing
specifically for inclusion therein.

         11.3 THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter
the "Indemnified Party") has received notice of or has knowledge of any claim by
a person not a party to this Agreement ("Third Person"), or the commencement of
any action or proceeding by a Third Person, 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 reasonably
satisfactory to the Indemnified Party, 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 or a conflict of
interest is reasonably likely to arise that prevents counsel for the
Indemnifying Party from representing such 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, 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


                                       42
<PAGE>   51


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. 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 pay the Indemnified Party
for the settlement amount 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. With respect to any account, note or other
receivable as to which the Stockholders have paid in full any indemnification
obligation pursuant to this Section 11 as a result of a breach of the
representation and warranty made pursuant to Section 5.11 or as to which a claim
in respect thereof has been asserted pursuant to this Section 11 that has been
applied against the Indemnification Threshold with respect to the Stockholders
as a result of a breach of the representation and warranty made pursuant to
Section 5.11, AmPaM shall cause the Company to assign such account, note or
other receivable to the Stockholders. 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. 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 to this Agreement with respect to any
provision of this Agreement, provided that, nothing herein shall be construed to
limit the right of a party, in a proper case, to seek injunctive relief for a
breach of this Agreement. AmPaM hereby waives, to the fullest extent permitted
under applicable law, any and all other rights, claims and causes of action,
known or unknown, it or any indemnified person may have against the Company or
any Stockholder relating to this Agreement or the transactions pursuant to this
Agreement arising under or based upon any Federal, state, local or foreign
statute, law, rule, regulation or otherwise. 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.

         11.5 LIMITATIONS ON INDEMNIFICATION. (a) AmPaM shall not assert any
claim for indemnification under this Section 11 against the Stockholders until
such time as, and solely to the extent that, the aggregate of all claims which
AmPaM may have against the Stockholders shall exceed the greater of (a) 3.0% of
the sum of (i) the cash paid to the Stockholders pursuant to Section 1.2 plus
(ii) the value of the AmPaM Stock delivered to the Stockholders pursuant to
Section 1.2


                                       43
<PAGE>   52


(calculated as provided in this Section 11.5) plus (iii) the principal amount of
the AmPaM Notes delivered to the Stockholders pursuant to Section 1.2, or (b)
$50,000 (the "Indemnification Threshold"). Stockholders shall not assert any
claim for indemnification hereunder against AmPaM until such time as, and solely
to the extent that, the aggregate of all claims which Stockholders may have
against AmPaM shall exceed $50,000; provided, however, that this sentence shall
not be applicable with respect of any failure by AmPaM to (i) deliver the
consideration specified in Annex I hereto on the Closing Date upon the
satisfaction, or waiver by AmPaM, of all conditions to the occurrence of the
Closing Date specified in Section 9 or (ii) comply with its obligations pursuant
to Section 10.1. After the $50,000 threshold for AmPaM (subject to the proviso
in the preceding sentence) or the Indemnification Threshold for a Stockholder
has been met, all claims must be made in $10,000 increments, which claims may be
cumulated in order to meet such $10,000 thresholds. For purposes of this
paragraph, the AmPaM Stock delivered to the Stockholders shall be valued at
$13.00 per share.

         (b) No person shall be entitled to indemnification under this Section
11 if and to the extent that such person's claim for indemnification is directly
or indirectly related to a breach by such person of any representation,
warranty, covenant or other agreement set forth in this Agreement. No claim for
indemnification against the Stockholders shall limit, diminish or change any
obligation of AmPaM pursuant to Section 10.1 hereof.

         (c) Notwithstanding any other term of this Agreement, no Stockholder
shall be liable under this Section 11 for an amount which exceeds eighty-five
percent (85%) of the amount of proceeds received by such Stockholder (valued as
of the Closing Date) in connection with the purchase and sale of the Company
Stock. For purposes of this paragraph, the AmPaM Stock shall be valued at $13.00
per share.

         (d) A Stockholder may pay any indemnification obligation under Section
11 by means of the payment of cash or a combination of the payment of cash, the
forgiveness of amounts owed pursuant to the AmPaM Notes and the delivery to
AmPaM of shares of AmPaM Stock; provided that the percentage of the
indemnification obligation satisfied by means of the delivery of shares of AmPaM
Stock does not exceed the percentage of AmPaM Stock comprising the total
consideration paid to such Stockholder by AmPaM to such Stockholder pursuant to
Annex I. For the purpose of crediting Stockholders for payments made to AmPaM by
means of delivery of shares of AmPaM Stock, the AmPaM Stock shall be valued at
$13.00 per share.

         (e) In determining the amount of any loss, liability or expense for
which any party is entitled to indemnification under this Agreement, the gross
amount thereof will be reduced by any correlative insurance proceeds or other
third party indemnity or reimbursement proceeds realized or to be realized by
such party (or, in the case of AmPaM, by AmPaM, the Company or any subsidiary of
AmPaM or the Company) and such correlative insurance proceeds or other third
party indemnity or reimbursement proceeds shall be net of any insurance premium
or other incremental cost or expense owed or payable to any third party which
becomes due as a result of such claim. AmPaM


                                       44
<PAGE>   53


shall use commercially reasonable efforts to pursue any available insurance
coverage or other rights of indemnity or reimbursement from third parties with
respect to any such loss, liability or expense.

12.      TERMINATION OF AGREEMENT

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

                  (i) by mutual consent of AmPaM and the Stockholders;

                  (ii) by the Stockholders, if the transactions contemplated by
         this Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by the Company
         or the Stockholders prior to or on the Closing Date;

                  (iii) by AmPaM, if the transactions contemplated by this
         Agreement to take place at the Closing Date shall not have been
         consummated by June 30, 1999, unless the failure of such transactions
         to be consummated is due to a breach of this Agreement by AmPaM prior
         to or on the Closing Date;

                  (iv) by the Stockholders, if a material breach or default
         shall be made by AmPaM in the observance or in the due and timely
         performance of any of the covenants or agreements contained herein
         relating to AmPaM, and the curing of such default shall not have been
         made (or in the reasonable judgment of such Stockholders cannot be
         made) on or before the Closing Date;

                  (v) by AmPaM, if a material breach or default shall be made by
         the Company or the Stockholders in the observance or in the due and
         timely performance of any of the covenants or agreements contained
         herein relating to the Company or the Stockholders, and the curing of
         such default shall not have been made (or in the reasonable judgment of
         AmPaM cannot be made) on or before the Closing Date;

                  (vi) by the Stockholders, if the conditions set forth in
         Section 8 hereof have not been satisfied or waived as of the Closing
         Date; or

                  (vii) by AmPaM, if the conditions set forth in Section 9
         hereof have not been satisfied or waived as of the Closing Date.

         12.2 PROCEDURE AND EFFECT OF TERMINATION. A determination to terminate
this Agreement by AmPaM pursuant to Section 12.1 shall be valid and effective
only if a written notice of termination, accompanied by a certified copy of
resolutions of the board of directors of AmPaM that evidence the authorization
of the officer of AmPaM to deliver a written notice of termination of this
Agreement pursuant to Section 12.1, is given to the Stockholders in the manner
specified for notices


                                       45
<PAGE>   54


in this Agreement. A determination to terminate this Agreement by the
Stockholders pursuant to Section 12.1 shall be valid and effective only if a
written notice of termination, signed by Stockholders who would be entitled to
receive a majority of the shares of AmPaM Stock specified in Section I of Annex
I to this Agreement if the transactions contemplated hereby were consummated, is
given to AmPaM in the manner specified for notices in this Agreement. Upon the
giving of notice of termination of this Agreement pursuant to Section 12.1 as
specified in the preceding sentence, this Agreement shall terminate, and the
transactions contemplated hereby shall be abandoned, without further action by
any of the parties hereto. Immediately upon any such termination, AmPaM shall
deliver written notice of such termination to the Other Founding Companies. If
this Agreement is terminated as provided in this Section 12, no party hereto
shall have any liability or further obligation hereunder to any other party,
except as provided in Section 14 and Section 18.6, provided, that, 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 that occurred prior to such termination.

13.      NONCOMPETITION

         13.1 PROHIBITED ACTIVITIES. The Stockholders will not, without the
prior written consent of AmPaM, for a period of two (2) years following the
Closing 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) 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, whether paid or unpaid, in any plumbing, piping,
         mechanical, heating, ventilation or air conditioning contracting,
         installation or services business or operation, whether for
         residential, commercial, industrial or governmental customers, or any
         ancillary contracting, installation or services business directly
         related thereto (such business and operations referred to herein as the
         "Plumbing and Mechanical Business"), within 100 miles of where the
         Company or any of its subsidiaries conducted business within two (2)
         years prior to the Closing Date (the "Territory");

                  (ii) call upon any person who is, at the Closing Date, within
         the Territory, an employee of AmPaM or any subsidiary thereof for the
         purpose or with the intent of enticing such employee away from or out
         of the employ of AmPaM or any subsidiary thereof;

                  (iii) call upon any person or entity which is, at the Closing
         Date, or which has been within three (3) years prior to the Closing
         Date, a customer of AmPaM or any subsidiary thereof, of the Company or
         of any of the Other Founding Companies for the purpose of soliciting
         customers, orders or contracts for any Plumbing and Mechanical Business
         in direct competition with AmPaM within the Territory;


                                       46
<PAGE>   55


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

                  (v) disclose to any person, firm, partnership, corporation or
         business the names or identities of any person, firm, partnership,
         corporation or business which has been a customer of the Company or any
         of its subsidiaries within the two (2) years prior to the Closing Date
         for any reason or purpose whatsoever except to the extent that the
         Company has in the past disclosed such information to the public for
         valid business reasons; or

                  (vi) testify as an expert witness in matters related to the
         Plumbing and Mechanical Business for an adverse party to AmPaM, the
         Company or any Other Founding Companies in litigation.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Stockholder from acquiring as a passive investment (i) not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange, the NASDAQ Stock Market or
over-the-counter, or (ii) not more than five percent (5%) of the capital stock
of a competing business whose stock is not publicly traded if the Board of
Directors of AmPaM consents to such acquisition.

         13.2 DAMAGES. Because of the difficulty of measuring economic losses to
AmPaM as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to AmPaM for which it
would have no other adequate remedy, each Stockholder agrees that the foregoing
covenant may be enforced by AmPaM 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 AmPaM and the
subsidiaries thereof on the date of the execution of this Agreement and the
current plans of AmPaM as described in the Private Placement Memorandum.

         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.


                                       47
<PAGE>   56


         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 AmPaM or any subsidiary thereof, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by AmPaM of such
covenants. It is specifically agreed that the period of two (2) 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
found to be in violation of any provision of this Section 13 as determined by
any of (i) a written agreement to such effect executed and delivered by AmPaM
and such Stockholder, (ii) a determination by an arbitration panel pursuant to
an arbitration conducted pursuant to Section 18.16 hereof or (iii) a
non-appealable judgment of a court of competent jurisdiction. The covenants
contained in Section 13 shall not be affected by any breach of any other
provision hereof by any party hereto. The covenants contained in Section 13
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
the covenants contained in this Section 13 are 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 AmPaM, such as operational policies, customer lists, and pricing and cost
policies that are valuable, special and unique assets of the Company's, the
Other Founding Companies' and/or AmPaM'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 AmPaM, (b) following the
Closing, such information may be disclosed by the Stockholders as is required in
the course of performing their duties for AmPaM or the Company and (c) to its
counsel and other advisers, provided that such advisers (other than counsel)
agree to the confidentiality provisions of this Section 14.1; provided, however
that (i) the foregoing disclosure prohibition shall not apply in the event that
(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 AmPaM and provide AmPaM 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, AmPaM 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 AmPaM from pursuing any other available remedy for such
breach or threatened breach, including the recovery of damages. In the event the
transactions contemplated


                                       48
<PAGE>   57


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 AMPAM. AmPaM recognizes and acknowledges that it had in the past
and currently has access to certain confidential information of the Company,
such as operational policies, customer lists, and pricing and cost policies that
are valuable, special and unique assets of the Company's business. AmPaM agrees
that, prior to the Closing, or if the transactions contemplated by this
Agreement are not consummated, it 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
the Company, (b) to its 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(b) of the Other Agreements and (d) to potential purchasers of
securities of AmPaM to the extent necessary or advisable in connection with the
applicable securities laws; provided, however that the foregoing disclosure
prohibition shall not apply in the event that (A) such information becomes known
to the public generally through no fault of AmPaM, (B) 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 (B), AmPaM
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 (C) 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 AmPaM of
the provisions of this Section 14.2, the Company and the Stockholders shall be
entitled to an injunction restraining AmPaM 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.
In the event the transactions contemplated by this Agreement are not consummated
for any reason, AmPaM shall nevertheless remain subject to this Section 14.2,
except that it shall not be permitted to make any disclosures otherwise than
pursuant to clause (A), (B) or (C) above.

         14.3 DAMAGES. Because of the difficulty of measuring economic losses as
a result of the breach of the foregoing covenants in Sections 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 by any of them of the foregoing covenants, the covenant may be
enforced against the other parties by injunctions and restraining orders.

         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 Closing Date.


                                       49

         14.5 RETURN OF INFORMATION. If the transactions contemplated by this
Agreement are not consummated, AmPaM will return or destroy all confidential
information regarding the Company.

15.      TRANSFER RESTRICTIONS

         15.1 TRANSFER RESTRICTIONS RELATING TO AMPAM STOCK AND AMPAM NOTES. For
a period of two years from the Closing Date or, in the event that the Company
completes an IPO, for a period through the second anniversary of the date of the
closing of such IPO (the "Restricted Period"), no Stockholder shall (i) sell,
assign, exchange, transfer, pledge, or otherwise dispose of any shares of AmPaM

AmPaM Stock or AmPaM Notes received by such Stockholder pursuant to this
Agreement, (ii) grant any option to purchase, or otherwise enter into any

transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of the AmPaM Stock or AmPaM Notes, whether any
such swap or transaction is to be settled by delivery of shares of AmPaM Stock
or AmPaM Notes or other securities, by the delivery or payment of cash or
otherwise, except, in the case of clauses (i), (ii) or (iii) above, (A) as
otherwise agreed by AmPaM, (B) for the sale of shares of AmPaM Stock, and
entering into agreements relating to the sale of shares of AmPaM Stock, pursuant
to Section 17 hereof, (C) for transfers to (I) immediate family members of such
Stockholder who agree with AmPaM in writing to be bound by the restrictions set
forth in this Section 15.1, (II) trusts, limited partnerships or other estate
planning entities for the benefit of such Stockholder or family members of such
Stockholder which have agreed with AmPaM in writing, through action taken by the
trustees, partners or other persons having authority to bind the trust, limited

forth in this Section 15.1, (III) any charitable organization that qualifies for
receipt of charitable contributions under Section 170(c) of the Code which

Section 15.1, (D) for transfers of AmPaM Stock or AmPaM Notes to AmPaM pursuant
to Section 11.5(d), (E) for transfers to another Stockholder, to another person
or entity who receives shares of AmPaM Stock or AmPaM Notes or AmPaM Series A
Preferred Stock pursuant to the Other Agreements or to Sterling City Capital LLC
or any of its Affiliates provided that (1) such transaction is exempt from the
registration requirements of the 1933 Act as evidenced by the delivery to AmPaM
of an opinion of counsel in form and substance reasonably satisfactory to AmPaM
and (2) any such transferee agrees in writing to be bound by the restrictions
set forth in this Section 15.1, (F) transfers of shares of AmPam Notes, shares
of AmPaM Stock, by such Stockholder to employees of the Company of up to an
aggregate of 15% of the shares of AmPaM Stock received by such Stockholder
pursuant to this Agreement provided that (1) any such transaction is exempt from
the registration requirements of the 1933 Act as evidenced by the delivery to
AmPaM of an opinion of counsel in form and substance reasonably satisfactory to
AmPaM and (2) any such employee agrees with AmPaM in writing to be bound by the
restrictions set forth in this Section 15.1 or (G) the sale by such Stockholder
in an IPO of shares of AmPaM Stock representing not more than 10% of the
Aggregate Consideration in cash; provided, however, that in no circumstance will
a Stockholder be


                                       50
<PAGE>   59


entitled to sell shares of AmPaM Stock in an IPO to the extent that the sale of
such shares by such Stockholder would result in such Stockholder receiving in
excess of 45% of the Aggregate Consideration in cash; and, provided further, if
AmPaM 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 Section 17.1 that the number of shares to be sold
by persons other than AmPaM is greater than the number of such shares which can
be offered without adversely affecting the success of the offering, AmPaM may
reduce pro rata (among the Stockholders and all other selling security holders
in the offering) 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. During the Restricted Period, the
certificates evidencing the AmPaM Stock or AmPaM Notes delivered to the
Stockholders pursuant to Section 3 of this Agreement will bear a legend
substantially in the form set forth below:

THE [SHARES/NOTES] REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
EXCHANGED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE
TERMS OF THE ACQUISITION AGREEMENT PURSUANT TO WHICH SUCH SHARES WERE ISSUED,
AND THE ISSUER SHALL NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED SALE,
ASSIGNMENT, EXCHANGE, TRANSFER, PLEDGE OR OTHER DISPOSITION PRIOR TO EXPIRATION
OF THE RESTRICTED PERIOD REFERRED TO IN THE ACQUISITION AGREEMENT EXCEPT IN
ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER ARE
SET FORTH IN AN ACQUISITION AGREEMENT, A COPY OF WHICH IS MAINTAINED AT THE
PRINCIPAL OFFICES OF THE ISSUER. 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.

         15.2 TRANSFER RESTRICTIONS RELATING TO ADDITIONAL CONSIDERATION. No
Stockholder shall (i) sell, assign, exchange, transfer, pledge, or otherwise
dispose of any right to receive any consideration pursuant to Section II of
Annex I to this Agreement (the "Additional Consideration Right") or any
securities convertible into, exchangeable or exercisable for any Additional
Consideration Right, (ii) grant any option to purchase, or otherwise enter into
any contract to sell, assign, transfer, pledge or otherwise dispose of, any
Additional Consideration Right, or (iii) enter into any swap or any other

indirectly, the economic consequence of ownership of any Additional
Consideration Right, whether any such swap or transaction is to be settled by
delivery of shares of AmPaM Stock or other securities, by the delivery or
payment of cash or otherwise.

16.      FEDERAL SECURITIES ACT REPRESENTATIONS

         16.1 COMPLIANCE WITH LAW. Each Stockholder acknowledges that the shares
of AmPaM Stock, the Additional Consideration Right and any AmPaM Notes to be
delivered to such 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 sold, assigned, exchanged, transferred, pledged or
otherwise disposed of without compliance with the 1933 Act which, among other
matters, would require registration under the 1933 Act unless exemption from the
registration requirements is available for such transaction. The AmPaM Stock,
the Additional Consideration Right and any AmPaM Notes to be acquired by each
Stockholder pursuant to this Agreement is being acquired solely for such
Stockholder's own account, for investment purposes only, and with no present
intention of selling, assigning, exchanging, transferring, pledging, or
otherwise disposing of it. Each Stockholder covenants, warrants and represents
that neither the shares of AmPaM Stock, the Additional Consideration Right nor
any AmPaM Notes issued to such Stockholder will be offered, sold, assigned,
exchanged, pledged, 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 certificates representing the AmPaM 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 FEDERAL AND STATE SECURITIES LAWS.

         16.2 ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear
the economic risk of an investment in the AmPaM Stock and AmPaM Notes to be
acquired pursuant to this Agreement and can afford to sustain a total loss of
such investment. Each Stockholder has substantial knowledge and experience in
making investment decisions of this type (or is relying on qualified purchaser
representatives with such knowledge and experience in making this decision), and
is capable, either individually or with such purchaser representatives, of
evaluating the merits and risks of this investment. Each Stockholder has had an
adequate opportunity to ask questions and receive answers from the officers of
AmPaM 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 AmPaM, the plans for the
operations of the business of AmPaM, the business, operations and financial
condition of the Founding Companies other than the Company, and any plans for
additional acquisitions. Each Stockholder has asked any and all questions of the
nature described in the preceding sentence and all questions have been answered
to such Stockholder's satisfaction. Except as set forth on Schedule 16.2, each
Stockholder is an "accredited investor" as defined in Rule 501(a) of the 1933
Act. Neither the foregoing nor any investigation made by the Stockholders
referred to above shall in any way affect the representations, warranties,
covenants and agreements of AmPaM made herein except to the extent that AmPaM is
relying upon the representations of the Stockholders in Section 16.1 and in this
Section 16.2 for purposes of


                                       52
<PAGE>   61


AmPaM's representations and warranties in Sections 6.9, 6.11, 6.15 and 6.17
hereof as specified therein.

         16.3 RELIANCE BY AmPaM. Each Stockholder acknowledges that AmPaM in
relying upon the representations and covenants of such Stockholder set forth in
Section 16.1 and Section 16.2 for purposes of compliance by AmPaM with Federal
and state securities laws related to the issuance of AmPaM Stock pursuant to
this Agreement and the Other Agreements.

17.      REGISTRATION RIGHTS

         17.1 PIGGYBACK REGISTRATION RIGHTS. Whenever AmPaM proposes to register
any AmPaM Stock for its own or other's 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 AmPaM and (ii)
registrations relating to employee benefit plans, AmPaM 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 15 calendar days after receipt
of such notice, notwithstanding the provisions of Section 15 (except as
specified below with respect to an IPO), AmPaM shall cause to be included in
such registration all of the AmPaM Stock issued to such 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 AmPaM as a stock split, dividend or other distribution with respect
to, or in exchange for, or in replacement of such AmPaM Stock) which any such
Stockholder requests, other than shares of AmPaM Stock which may then be
immediately sold under Rule 144(k) (or any similar or successor provision)
promulgated under the 1933 Act, and other than shares of AmPaM Stock that have
been theretofore sold by the Stockholder in accordance with the 1933 Act,
provided that AmPaM shall have the right to reduce pro rata the number of shares
of each selling Stockholder included in such registration to the extent that
inclusion of such shares would, in the written opinion of tax counsel to AmPaM
or its independent auditors, jeopardize the status of the transactions
contemplated hereby and by the Private Placement Memorandum as a tax-free
organization under Section 351 of the Code; provided, however, that with respect
to a proposal by AmPaM to register AmPaM Stock under the 1933 Act in connection
with an IPO, no Stockholder shall be permitted pursuant to this Section 17.1 to
have included in such registration more shares of AmPaM Stock than permitted to
be sold by such Stockholder pursuant to Section 15.1. In addition, if AmPaM 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 AmPaM is greater than the number of such shares which can be offered
without adversely affecting the success of the offering, AmPaM may reduce pro
rata (among the Stockholders and all other selling security holders in the
offering) 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. If any Stockholder disapproves of the terms of the
underwriting, that Stockholder may elect to withdraw therefrom by written notice
to AmPaM and the managing underwriter. That Stockholder's shares of AmPaM Stock
so withdrawn shall also be withdrawn from registration; provided, however, that,
if by the withdrawal of such shares a greater number of shares of AmPaM


                                       53
<PAGE>   62


Stock held by other Stockholders may be included in such registration, then
AmPaM shall offer to all other Stockholders of AmPaM the right to include
additional shares in the same proportion used in effecting the above
limitations. AmPaM shall not, for a period of two years following the Closing
Date, grant to any other person any rights to cause AmPaM to register any
securities in priority over, or in precedent to, the rights granted to the
Stockholders hereunder and to the stockholders of the Other Founding Companies
pursuant to Section 17 of the Other Agreements.

         17.2 REGISTRATION PROCEDURES. Whenever AmPaM is required to register
shares of AmPaM Stock pursuant to Section 17.1, AmPaM 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, AmPaM will furnish a representative of the
         Stockholders with copies of all such documents proposed to be filed) as
         promptly as practical;

                  (ii) Notify the Stockholders of any stop order issued or
         threatened by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it if entered;

                  (iii) 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, cause the
         prospectus to be supplemented by any required prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the 1933
         Act; and comply with the provisions of the 1933 Act applicable to it
         with respect to the disposition of all securities covered by such
         registration statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such registration statement or supplement to the prospectus;

                  (iv) 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;

                  (v) Make "generally available to its security holders" (within
         the meaning of Rule 158) an earnings statement satisfying the
         provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder no
         later than 90 days after the end of the 12-month period beginning with
         the first day of AmPaM's first fiscal quarter commencing after the
         effective date of the registration statement;


                                       54

<PAGE>   63



                  (vi) Make every reasonable effort to obtain the withdrawal of
         any order suspending the effectiveness of the registration statement at
         the earliest possible moment;

                  (vii) If requested by the managing underwriter or
         underwriters, if any, or any participating Stockholder, promptly
         incorporate in a prospectus supplement or post-effective amendment such
         information as the managing underwriter or underwriters or any
         participating Stockholder, as the case may be, reasonably requests to
         be included therein, including, without limitation, information with
         respect to the number of shares of AmPaM Stock being sold by
         participating Stockholders to any underwriter or underwriters, the
         purchase price being paid therefor by such underwriter or underwriters
         and with respect to any other terms of an underwritten offering of the
         shares of AmPaM Stock to be sold in such offering, and promptly make
         all required filings of such prospectus by supplement or post-effective
         amendment;

                  (viii) Make available for inspection by participating
         Stockholders, any underwriter participating in any disposition pursuant
         to such registration statement, and the counsel retained by the
         participating Stockholders, counsel for the underwriters and any
         accountant or other agent retained by participating Stockholders or any
         such underwriter (collectively, the "Inspectors"), all financial and
         other records, pertinent corporate documents and properties of AmPaM
         (the "Records"), as shall be reasonably necessary to enable them to
         exercise their due diligence responsibility, and cause AmPaM's
         officers, directors and employees to supply all information reasonably
         requested by any such Inspectors in connection with such registration
         statement; provided, that records which AmPaM determines, in good
         faith, to be confidential and which AmPaM notifies the Inspectors are
         confidential shall not be disclosed by the Inspectors unless (i) the
         disclosure of such Records is necessary to avoid or correct a
         misstatement or omission in the registration statement or (ii) the
         release of such Records is ordered pursuant to a subpoena or other
         order from a court of competent jurisdiction after delivery of
         sufficient notice to AmPaM to enable AmPaM to contest such subpoena or
         order;

                  (ix) Take all other steps reasonably necessary to effect the
         registration of the shares of AmPaM Stock contemplated hereby;

                  (x) 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 required to
         be kept effective, provided that AmPaM shall not be required to become
         subject to taxation, to qualify generally to do business or to file a
         general consent to service of process in any such states or
         jurisdictions;

                  (xi) Cause all such shares of AmPaM Stock to be listed or
         included not later than the date of the first sale of shares of AmPaM
         Stock under such registration statement on any


                                       55
<PAGE>   64


         securities exchanges or trading systems on which similar securities
         issued by AmPaM are then listed or included; and

                  (xii) Notify each Stockholder at any time when a prospectus
         relating thereto is required to be delivered under the 1933 Act within
         the period that AmPaM 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 (as then in effect),
         together with any associated term sheet, contains an untrue statement
         of a material fact or omits to state any fact required to be stated
         therein or necessary to make the statements therein (in the case of the
         prospectus or any preliminary prospectus, in light of the circumstances
         under which they were made) not misleading, and, at the request of such
         Stockholder, AmPaM promptly 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 required to be
         stated therein or necessary to make the statements therein (in the case
         of the prospectus or any preliminary prospectus, in light of the
         circumstances under which they were made) not misleading.

         All expenses incurred in connection with the registration under this
Article 17 and compliance with securities and blue sky laws (including all
registration, filing, listing, escrow agent, qualification, legal, printer and
accounting fees, but excluding underwriting commissions and discounts), shall be
borne by AmPaM.

         17.3     INDEMNIFICATION.

                  (a) In connection with any registration under Section 17.1,
AmPaM shall indemnify, to the extent permitted by law, each selling Stockholder
(an "Indemnified Party") against all losses, claims, damages, liabilities and
expenses arising out of or resulting from any untrue or alleged untrue statement
of material fact contained or incorporated by reference in any registration
statement, prospectus or preliminary prospectus or associated term sheet or any
omission or alleged omission to state or incorporated by reference therein a
material fact required to be stated or incorporated by reference 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 AmPaM 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 AmPaM has furnished
such Indemnified Party with a sufficient number of copies of the same.

                  (b) In connection with any registration under Section 17.1,
each selling Stockholder shall furnish to AmPaM in writing such information
concerning the Stockholder and his or her proposed offering of shares as is
reasonably requested by AmPaM for use in any such registration statement or
prospectus and will indemnify, to the extent permitted by law, AmPaM, its
directors and officers and each person who controls AmPaM (within the meaning of
the 1933 Act) against any losses, claims, damages, liabilities and expenses
resulting from any untrue or alleged


                                       56
<PAGE>   65


untrue statement of a material fact or any omission or alleged omission to state
therein a material fact required to be stated in the registration statement or
prospectus or any amendment thereof or supplement thereto or necessary to make
the statements therein not misleading, but only to the extent that such untrue
or alleged untrue statement or omission or alleged omission is contained in or
omitted from information so furnished in writing to AmPaM by such Stockholder
expressly for use in 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 hereunder 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 that 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 Sections 17.1 covering an underwritten registered offering, (i) each
participating Stockholder shall execute and deliver to AmPaM a written power of
attorney instrument that (A) appoints an officer of AmPaM as such Stockholder's
attorney-in-fact for purposes of executing and delivering an underwriting
agreement among AmPaM, the underwriters named therein and such Stockholder
specifying the terms and conditions applicable to the sale of AmPaM Stock of
such Stockholder in such offering and (B) otherwise is in such form and
containing such provisions as are customary in the securities business for such
an arrangement in connection with an underwritten registered offering in which
one or more stockholders of the issuer are participants, including a provision
that authorizes the attorney-in-fact appointed by such Stockholder to execute
and deliver such an underwriting agreement in the event that the net price per
share to be received by such Stockholder from the sale of the shares of AmPaM
Stock to be sold in such offering is not less than a price specified in such
instrument and (iii) AmPaM and each participating Stockholder 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 AmPaM's size
and investment stature, including indemnification; provided, however, that (A)
such Stockholder shall be exempt and excluded from any indemnification of the
managing underwriters other than with respect to information provided by such
Stockholder with respect to such Stockholder to AmPaM or the managing
underwriters


                                       57
<PAGE>   66


specifically for inclusion in any such registration statement and (B) such
Stockholder shall not be obligated to enter into such an underwriting agreement
in the event that the net price per share to be received by such Stockholder
from the sale of shares of AmPaM Stock to be sold in such offering is less than
the floor price specified in the power of attorney instrument executed and
delivered to AmPaM pursuant to clause (i) above.

         17.5 TRANSFER OF RIGHTS. The right to cause AmPaM to register shares of
AmPaM Stock under this Agreement may be assigned to a transferee or assignee of
any Stockholder to the extent that such transferee or assignee is a member of
the immediate family of a Stockholder, a trust, limited partnership or other
estate planning entity for the benefit of any such persons or a charitable
organization that qualifies for receipt of charitable contributions under
Section 170(c) of the Code.

         17.6 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 AmPaM
stock to the public without registration, following an IPO AmPaM agrees to use
its reasonable efforts, from and after the completion of an IPO, to:

                  (i) make and keep public information regarding AmPaM available
         as those terms are understood and defined in Rule 144 under the 1933
         Act beginning 90 days following the effective date of a registration
         statement relating to an IPO;

                  (ii) file with the SEC in a timely manner all reports and
         other documents required of AmPaM 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 AmPaM
         Stock, furnish to each Stockholder forthwith upon written request a
         written statement by AmPaM as to its compliance with the current public
         information requirements of Rule 144 (at any time from and after 90
         days following the effective date of a registration statement relating
         to an IPO), 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 AmPaM, 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.      REDEMPTION OF AmPaM STOCK

         18.1 REDEMPTION TRIGGER. In the event that, within three years of the
Closing Date, (i) AmPaM has not consummated an IPO and (ii) any Stockholder has
not received cash (including proceeds from the public or private sale of AmPaM
Stock received as consideration hereunder and the receipt of principal payments,
if any, made with respect to AmPaM Notes held by such Stockholder) equal to or
exceeding 50% of the Aggregate Consideration on or prior to the third
anniversary of the Closing Date, such Stockholder shall have the right (the "Put
Right"), but not the obligation, commencing on the third anniversary date of the
Closing Date to require AmPaM to


                                       58
<PAGE>   67


purchase a number of shares of AmPaM Stock then owned by such Stockholder,
subject to the limitations set forth in Section 18.2 below. The purchase price
for such redemption shall be $13.00 per share, such price to be subject to
appropriate adjustment to reflect any reclassification, stock dividend,
subdivision, split-up or combination of shares of AmPaM Stock after the date
hereof.

         18.2 MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 18.1(i) and 18.1(ii), with Section 18.1(ii) being determined on an
individual Stockholder basis, have not occurred within the time specified, AmPaM
shall be obligated to purchase from each eligible Stockholder no less than 10%
of the AmPaM Stock held by such Stockholder annually; provided, however, that
the Stockholders shall not be entitled to exercise their Put Rights if and to
the extent the Company has not achieved the Target Net Income (as defined in
Annex I hereto) for the year preceding the year in which a Stockholder seeks to
exercise his Put Right. The redemptions will be funded by internal cash flows or
alternative financing arrangements but AmPaM's obligation to make any redemption
pursuant to this Section 18 will be subject to the covenants and restrictions
contained in AmPaM's then existing private or public debt or equity instruments.

         18.3 NOTICE; EXERCISE. The Stockholders may exercise their Put Right by
giving written notice (the "Put Notice") to AmPaM within thirty (30) days of the
third anniversary of the execution hereof. If any Stockholder does not provide
AmPaM with a Put Notice within such thirty-day period, the Put Right applicable
to such Stockholder shall expire. The date for closing the sale of any shares of
AmPaM Stock pursuant to a proper exercise of a Put Right shall in no event be
earlier than 90 days after the date AmPaM receives the Put Notice. Any such
closing shall be at such time of day and place as shall be mutually agreed
between such holder and AmPaM. At such closing AmPaM shall make payment for the
AmPaM Stock to be repurchased by wire transfer of immediately available funds to
a bank account designated by such Stockholder for such purpose and such
Stockholder shall deliver to AmPaM certificates, duly endorsed for transfer,
representing the shares of AmPaM Stock to be purchased and sold pursuant to the
exercise of such Put Right.

         18.4 ADDITIONAL REDEMPTIONS. In the event AmPaM has not consummated an
IPO and notwithstanding the foregoing, to the extent the Stockholders who have
received greater than 50% of their Aggregate Consideration in cash wish to
tender AmPaM Stock to AmPaM for purchase, AmPaM will use its commercially
reasonable efforts to continue to repurchase up to 10% of the AmPaM Stock held
by such Stockholder annually.

         18.5 TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect to
any individual Stockholder will terminate upon receipt by such Stockholder of
50% of his Aggregate Consideration in cash; such termination will not, however,
limit such Stockholders ability to participate in the additional redemptions
provided in Section 18.4. Notwithstanding the foregoing, all of AmPaM's
redemption obligations contained in this Section 18 shall terminate on the
earlier to occur of (i) an IPO, (ii) any sale of all or substantially all of
AmPaM's assets in one transaction or series of transactions, (iii) any merger or
consolidation which involves AmPaM and in which AmPaM is not the surviving
entity or (iv) any transaction after which the shares of AmPaM Common Stock, if
any, which are then held by persons other than the holders of AmPaM Common Stock
as of the Closing


                                       59
<PAGE>   68


Date constitute 50% or more of AmPaM Common Stock outstanding as of the date of
the consummation of such transaction.

19.      GENERAL

         19.1 COOPERATION. The Company, Stockholders and AmPaM shall each
deliver or cause to be delivered to the other on the Closing 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
AmPaM on and after the Closing 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 Closing Date.

         19.2 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law and except as

benefit of the parties hereto, the successors of AmPaM and the Company, and the
heirs, successors and legal representatives of the Stockholders.

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

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 by
a written instrument executed by the Stockholders, the Company and AmPaM, 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.

         19.4 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. A telecopied
facsimile of an executed counterpart of this Agreement shall be sufficient to
evidence the binding agreement of each party to the terms hereof. However, each
party agrees to return to the other parties an original, duly executed
counterpart of this Agreement promptly after delivery of a telecopied facsimile
thereof.

         19.5 BROKERS AND AGENT. Except as disclosed on Schedule 18.5, each
party hereto 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.

         If the undersigned is not a broker-dealer, the undersigned represents
that it is not engaged in, and does not intend to engage in, a distribution of
Exchange Notes. If the undesigned is a broker-dealer that will receive Exchange
Notes for its own account in exchange for Old Notes that were acquired as a
result of market-making activities or other trading activities, it acknowledges
that it will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.


                     NOTE: SIGNATURES MUST BE PROVIDED BELOW
                 PLEASE READ ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

         Subject to the terms and conditions of the Exchange Offer, the
undersigned hereby tenders to American Plumbing & Mechanical, Inc. (the
"Company") the principal amount of Old Notes indicated above.

         Subject to and effective upon the acceptance for exchange of the
principal amount of Old Notes tendered hereby in accordance with this Letter of
Transmittal, the undersigned sells, assigns and transfers to, or upon the order
of, the Company all right, title and interest in and to the Old Notes tendered
hereby. The undersigned hereby irrevocably constitutes and appoints the Exchange
Agent as its agent and attorney-in-fact (with full knowledge that the Exchange
Agent also acts as the agent of the Company and as Trustee and Registrar under
the Indenture for the Old Notes and the Exchange Notes) with respect to the
tendered Old Notes with full power of substitution (such power of attorney being
deemed an irrevocable power coupled with an interest), subject only to the right
of withdrawal described in the Prospectus, to (i) deliver certificates for such
Old Notes to the Company or transfer ownership of such Old Notes on the account
books maintained by DTC, together, in either such case, with all accompanying
evidences of transfer and authenticity to, or upon the order of, the Company and
(ii) present such Old Notes for transfer on the books of the Company and receive
all benefits and otherwise exercise all rights of beneficial ownership of such
Old Notes, all in accordance with the terms of the Exchange Offer.

         The undersigned acknowledges that the Exchange Offer is being made in
reliance upon interpretative advice given by the staff of the Securities and
Exchange Commission to third parties in connection with transactions similar to
the Exchange Offer, so that the Exchange Notes issued pursuant to the Exchange
Offer in exchange for the Old Notes may be offered for resale, resold and
otherwise transferred by holders thereof (other than a broker-dealer who
purchased

                                       -5-

<PAGE>   6



such Old Notes directly from the Company for resale pursuant to Rule 144A or any
other available exemption under the Securities Act or a person that is an
"affiliate" of the Company or any Guarantor within the meaning of Rule 405 under
the Securities Act) without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such Exchange Notes are
acquired in the ordinary course of such holders' business and such holders have
no arrangement with any person to participate in the distribution of such
Exchange Notes.

         The undersigned agrees that acceptance of any tendered Old Notes by the
Company and the issuance of Exchange Notes in exchange therefor shall constitute
performance in full by the Company of its obligations under the registration
rights agreement, (as referred to in the Prospectus) and that, upon the issuance
of the Exchange Notes, the Company will have no further obligations or
liabilities thereunder (except in certain limited circumstances).

         The undersigned represents and warrants that (i) the Exchange Notes
acquired pursuant to the Exchange Offer are being acquired in the ordinary
course of business of the person receiving Exchange Notes (which shall be the
undersigned unless otherwise indicated in the box entitled "Special Delivery
Instructions" above) (the "Recipient"), (ii) neither the undersigned nor the
Recipient (if different) is engaged in, intends to engage in or has any
arrangement or understanding with any person to participate in the distribution
of such Exchange Notes, and (iii) neither the undersigned nor the Recipient (if
different) is an "affiliate" of the Company or any Guarantor as defined in Rule
405 under the Securities Act. If the undersigned is not a broker-dealer, the
undersigned further represents that it is not engaged in, and does not intend to
engage in, a distribution of the Exchange Notes. If the undersigned is a
broker-dealer, the undersigned further (x) represents that it acquired Old Notes
for the undersigned's own account as a result of market-making activities or
other trading activities, (y) represents that it has not entered into any
arrangement or understanding with the Company or any "affiliate" of the Company
(within the meaning of Rule 405 under the Securities Act) to distribute the
Exchange Notes to be received in the Exchange Offer and (z) acknowledges that it
will deliver a prospectus meeting the requirements of the Securities Act (for
which purposes delivery of the Prospectus, as the same may be hereafter
supplemented or amended, shall be sufficient) in connection with any resale of
Exchange Notes received in the Exchange Offer. Such a broker-dealer will not be
deemed, solely by reason of such acknowledgment and prospectus delivery, to
admit that it is an "underwriter" within the meaning of the Securities Act.

         The undersigned understands and agrees that the Company reserves the
right not to accept tendered Old Notes from any tendering holder if the Company
determines, in its sole and absolute discretion, that such acceptance could
result in a violation of applicable securities laws.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the Old Notes
tendered hereby and to acquire Exchange Notes issuable upon the exchange of such
tendered Old Notes, and that, when the same are accepted for exchange, the
Company will acquire good and unencumbered title thereto, free and clear of all
liens, restrictions, charges and encumbrances and not subject to any adverse
claim. The undersigned also warrants that it will, upon request, execute and
deliver any additional documents deemed to be necessary or desirable by the
Exchange Agent or the Company in order to complete the exchange, assignment and
transfer of tendered Old Notes or transfer of ownership of such Old Notes on the
account books maintained by a book-entry transfer facility.

         The undersigned understands and acknowledges that the Company reserves
the right in its sole discretion to purchase or make offers for any Old Notes
that remain outstanding subsequent to the Expiration Date or, as set forth in
the Prospectus under the caption "The Exchange Offer--Procedures for Tendering,"
to terminate the Exchange Offer and, to the extent permitted by applicable law,
purchase Old Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers could differ from the terms
of the Exchange Offer.

         The undersigned understands that the Company may accept the
undersigned's tender by delivering written notice of acceptance to the Exchange
Agent, at which time the undersigned's right to withdraw such tender will
terminate. For purposes of the Exchange Offer, the Company shall be deemed to
have accepted validly tendered Old Notes when, as and if the Company has given
oral (which shall be confirmed in writing) or written notice thereof to the
Exchange Agent.

                                       -6-

<PAGE>   7




         The undersigned understands that the first interest payment following
the Expiration Date will include unpaid interest on the Old Notes accrued
through the date of issuance of the Exchange Notes.

         The undersigned understands that tenders of Old Notes pursuant to the
procedures described under the caption "The Exchange Offer--Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and the Company upon the terms and
subject to the conditions of the Exchange Offer.

         The undersigned acknowledges that the Exchange Offer is subject to the
more detailed terms set forth in the Prospectus and, in case of any conflict
between the terms of the Prospectus and this Letter of Transmittal, the
Prospectus shall prevail.

         If any tendered Old Notes are not accepted for exchange pursuant to the
Exchange Offer for any reason, certificates for any such unaccepted Old Notes
will be returned (except as noted below with respect to tenders through DTC), at
the Company's cost and expense, to the undersigned at the address shown below or
at a different address as may be indicated herein under "Special Delivery
Instructions" as promptly as practicable after the Expiration Date.

         All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representatives, successors and assigns. This tender may be withdrawn only in
accordance with the procedures set forth in this Letter of Transmittal.

         By acceptance of the Exchange Offer, each broker-dealer that receives
Exchange Notes pursuant to the Exchange Offer hereby acknowledges and agrees
that upon the receipt of notice by the Company of the happening of any event
which makes any statement in the Prospectus untrue in any material respect or
which requires the making of any changes in the Prospectus in order to make the
statements therein not misleading (which notice the Company agrees to deliver
promptly to such broker-dealer), such broker-dealer will suspend use of the
Prospectus until the Company has amended or supplemented the Prospectus to
correct such misstatement or omission and has furnished copies of the amended or
supplemented prospectus to such broker-dealer.

         Unless otherwise indicated under "Special Registration Instructions,"
please issue the certificates representing the Exchange Notes issued in exchange
for the Old Notes accepted for exchange and return any certificates for Old
Notes not tendered or not exchanged, in the name(s) of the undersigned (or, in
either such event in the case of Old Notes tendered by DTC, by credit to the
account at DTC). Similarly, unless otherwise indicated under "Special Delivery
Instructions," please send the certificates representing the Exchange Notes
issued in exchange for the Old Notes accepted for exchange and any certificates
for Old Notes not tendered or not exchanged (and accompanying documents, as
appropriate) to the undersigned at the address shown below the undersigned's
signature(s), unless, in either event, tender is being made through DTC. In the
event that both "Special Registration Instructions" and "Special Delivery
Instructions" are completed, please issue the certificates representing the
Exchange Notes issued in exchange for the Old Notes accepted for exchange in the
name(s) of, and return any certificates for Old Notes not tendered or not
exchanged to, the person(s) so indicated. The undersigned understands that the
Company has no obligations pursuant to the "Special Registration Instructions"
or "Special Delivery Instructions" to transfer any Old Notes from the name of
the registered Holder(s) thereof if the Company does not accept for exchange any
of the Old Notes so tendered.

         Holders who wish to tender the Old Notes and (i) whose Old Notes are
not immediately available or (ii) who cannot deliver their Old Notes, this
Letter of Transmittal or any other documents required hereby to the Exchange
Agent prior to the Expiration Date, may tender their Old Notes according to the
guaranteed delivery procedures set forth in the Prospectus under the caption
"The Exchange Offer--Guaranteed Delivery Procedures." See Instruction 1
regarding the completion of the Letter of Transmittal.

                         PLEASE SIGN HERE WHETHER OR NOT
                 OLD NOTES ARE BEING PHYSICALLY TENDERED HEREBY
                     AND WHETHER OR NOT TENDER IS TO BE MADE

                                  INSTRUCTIONS

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER


         1. Guarantee of Signatures. Signatures on this Letter of Transmittal
need not be guaranteed if (a) this Letter of Transmittal is signed by the
registered holder(s) of the Old Notes tendered herewith and such holder(s) have
not completed the box set forth herein entitled "Special Registration
Instructions" or the box entitled "Special Delivery Instructions" or (b) such
Old Notes are tendered for the account of an Eligible Institution. (See
Instruction 6.) Otherwise, all signatures on this Letter of Transmittal or a
notice of withdrawal, as the case may be, must be guaranteed by a member firm of
a registered national securities exchange or of the National Association of
Securities Dealers, Inc. or a commercial bank or trust company having an office
or correspondent in the United States (an "Eligible Institution"). All
signatures on bond powers and endorsements on certificates must also be
guaranteed by an Eligible Institution.

         2. Delivery of this Letter of Transmittal and Old Notes. Certificates
for all physically delivered Old Notes or confirmation of any book-entry
transfer to the Exchange Agent at DTC of Old Notes tendered by book-entry
transfer, as well as, in each case (including cases where tender is affected by
book-entry transfer), a properly completed and duly executed copy of this Letter
of Transmittal or facsimile hereof and any other documents required by this
Letter of Transmittal must be received by the Exchange Agent at its address set
forth herein prior to 5:00 p.m., New York City time, on the Expiration Date.

         The method of delivery of the tendered Old Notes, this Letter of
Transmittal and all other required documents to the Exchange Agent is at the
election and risk of the Holder and the delivery will be deemed made only when
actually received by the Exchange Agent. If Old Notes are sent by mail,
registered mail with return receipt requested, properly insured, is recommended.
In all cases, sufficient time should be allowed to ensure timely delivery. No
Letter of Transmittal or Old Notes should be sent to the Company.

         The Exchange Agent will make a request to establish an account with
respect to the Old Notes at the Depositary for purposes of the Exchange Offer
within two business days after receipt of this Prospectus, and any financial
institution that is a participant in the Depositary may make book-entry delivery
of Old Notes by causing the Depositary to transfer

                                       -9-

<PAGE>   10



such Old Notes into the Exchange Agent's account at the Depositary in accordance
with the Depositary's procedures for transfer. However, although delivery of Old
Notes may be effected through book-entry transfer at the Depositary, the Letter
of Transmittal, with any required signature guarantees or an Agent's Message (as
defined below) in connection with a book-entry transfer and any other required
documents, must, in any case, be transmitted to and received by the Exchange
Agent at the address specified on the cover page of the Letter of Transmittal on
or prior to the Expiration Date or the guaranteed delivery procedures described
below must be complied with.

         A Holder may tender Old Notes that are held through the Depositary by
transmitting its acceptance through the Depositary's Automatic Tender Offer
Program, for which the transaction will be eligible, and the Depositary will
then edit and verify the acceptance and send an Agent's Message to the Exchange
Agent for its acceptance. The term "Agent's Message" means a message transmitted
by the Depositary to, and received by, the Exchange Agent and forming part of
the Book-Entry Confirmation, which states that the Depositary has received an
express acknowledgment from each participant in the Depositary tendering the Old
Notes and that such participant has received the Letter of Transmittal and
agrees to be bound by the terms of the Letter of Transmittal and the Company may
enforce such agreement against such participant.

         Holders who wish to tender their Old Notes and (i) whose Old Notes are
not immediately available, or (ii) who cannot deliver their Old Notes, this
Letter of Transmittal or any other documents required hereby to the Exchange
Agent prior to the Expiration Date or comply with book-entry transfer procedures
on a timely basis must tender their Old Notes according to the guaranteed
delivery procedures set forth in the Prospectus. See "Exchange Offer
- --Guaranteed Delivery Procedures." Pursuant to such procedure: (i) such tender
must be made by or through an Eligible Institution; (ii) prior to the Expiration
Date, the Exchange Agent must have received from the Eligible Institution a
properly completed and duly executed Notice of Guaranteed Delivery (by facsimile
transmission, overnight courier, mail or hand delivery) setting forth the name
and address of the Holder of the Old Notes, the certificate number or numbers of
such Old Notes and the principal amount of Old Notes tendered, stating that the
tender is being made thereby and guaranteeing that, within three New York Stock
Exchange trading days after the Expiration Date, this Letter of Transmittal (or
facsimile hereof) together with the certificate(s) representing the Old Notes
and any other required documents will be deposited by the Eligible Institution
with the Exchange Agent; and (iii) such properly completed and executed Letter
of Transmittal (or facsimile hereof), as well as all other documents required by
this Letter of Transmittal and the certificate(s) representing all tendered Old
Notes in proper form for transfer (or a confirmation of book-entry transfer of
such Old Notes into the Exchange Agent's account at DTC), must be received by
the Exchange Agent within three New York Stock Exchange trading days after the
Expiration Date, all in the manner provided in the Prospectus under the caption
"The Exchange Offer--Guaranteed Delivery Procedures." Any Holder who wishes to
tender his Old Notes pursuant to the guaranteed delivery procedures described
above must ensure that the Exchange Agent receives the Notice of Guaranteed
Delivery prior to 5:00 p.m., New York City time, on the Expiration Date. Upon
request to the Exchange Agent, a Notice of Guaranteed Delivery will be sent to
Holders who wish to tender their Old Notes according to the guaranteed delivery
procedures set forth above.

         All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes, and withdrawal of tendered Old Notes
will be determined by the Company in its sole discretion, which determination
will be final and binding. All tendering holders, by execution of this Letter of
Transmittal (or facsimile thereof), shall waive any right to receive notice of
the acceptance of the Old Notes for exchange. The Company reserves the absolute
right to reject any and all Old Notes not properly tendered or any Old Notes the
Company's acceptance of which would, in the opinion of counsel for the Company,
be unlawful. The Company also reserves the right to waive any irregularities or
conditions of tender as to particular Old Notes. The Company's interpretation of
the terms and conditions of the Exchange Offer (including the instructions in
this Letter of Transmittal) shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
must be cured within such time as the Company shall determine. Neither the
Company, the Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Old Notes,
nor shall any of them incur any liability for failure to give such notification.
Tenders of Old Notes will not be deemed to have been made until such defects or
irregularities have been cured to the Company's satisfaction or waived. Any Old
Notes received by the Exchange Agent that are not properly tendered and as to
which the defects or irregularities have not been cured or waived will be
returned by the Exchange Agent to the tendering Holders pursuant to the
Company's determination, unless otherwise provided in this Letter of Transmittal
as soon as practicable following the Expiration Date. The Exchange Agent has no
fiduciary duties to the Holders with respect to the Exchange Offer and is acting
solely on the basis of directions of the Company.


                                      -10-

<PAGE>   11




         3. Inadequate Space. If the space provided is inadequate, the
certificate numbers and/or the number of Old Notes should be listed on a
separate signed schedule attached hereto.

         4. Tender by Holder. Only a Holder of Old Notes may tender such Old
Notes in the Exchange Offer. Any beneficial owner of Old Notes who is not the
registered Holder and who wishes to tender should arrange with such registered
holder to execute and deliver this Letter of Transmittal on such beneficial
owner's behalf or must, prior to completing and executing this Letter of
Transmittal and delivering his Old Notes, either make appropriate arrangements
to register ownership of the Old Notes in such beneficial owner's name or obtain
a properly completed bond power from the registered holder or properly endorsed
certificates representing such Old Notes.

         5. Partial Tenders; Withdrawals. Tenders of Old Notes will be accepted
only in integral multiples of $1,000. If less than the entire principal amount
of any Old Notes is tendered, the tendering Holder should fill in the principal
amount tendered in the third column of the box entitled "Description of 115/8%
Senior Subordinated Notes due 2008, Series A" above. The entire principal amount
of any Old Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated. If the entire principal amount of all Old
Notes is not tendered, then Old Notes for the principal amount of Old Notes not
tendered and a certificate or certificates representing Exchange Notes issued in
exchange for any Old Notes accepted will be sent to the Holder at his or her
registered address, unless a different address is provided in the "Special
Delivery Instructions" box above on this Letter of Transmittal or unless tender
is made through DTC, promptly after the Old Notes are accepted for exchange.

         Except as otherwise provided herein, tenders of Old Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date. To withdraw a tender of Old Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having deposited the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes, or, in the case of Old Notes
transferred by book-entry transfer the name and number of the account at DTC to
be credited), (iii) be signed by the Depositor in the same manner as the
original signature on the Letter of Transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Registrar with respect to the Old
Notes register the transfer of such Old Notes into the name of the person
withdrawing the tender and (iv) specify the name in which any such Old Notes are
to be registered, if different from that of the Depositor. All questions as to
the validity, form and eligibility (including time of receipt) of such notices
will be determined by the Company, whose determination shall be final and
binding on all parties. Any Old Notes so withdrawn will be deemed not to have
been validly tendered for purposes of the Exchange Offer and no Exchange Notes
will be issued with respect thereto unless the Old Notes so withdrawn are
validly retendered. Any Old Notes which have been tendered but which are not
accepted for exchange by the Company will be returned to the Holder thereof
without cost to such Holder as soon as practicable after withdrawal, rejection
of tender or termination of the Exchange Offer. Properly withdrawn Old Notes may
be retendered by following one of the procedures described in the Prospectus
under "The Exchange Offer--Procedures for Tendering" at any time prior to the
Expiration Date.

         6. Signatures on the Letter of Transmittal; Bond Powers and
Endorsements. If this Letter of Transmittal (or facsimile hereof) is signed by
the registered holder(s) of the Old Notes tendered hereby, the signature must
correspond with the name(s) as written on the face of the Old Note without
alteration, enlargement or any change whatsoever.

         If any of the Old Notes tendered hereby are owned of record by two or
more joint owners, all such owners must sign this Letter of Transmittal.

         If a number of Old Notes registered in different names are tendered, it
will be necessary to complete, sign and submit as many copies of this Letter of
Transmittal as there are different registrations of Old Notes.

         If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder or Holders (which term, for the Purposes described herein,
shall include a book-entry transfer facility whose name appears on a security
listing as the owner of the Old Notes) of Old Notes tendered and the certificate
or certificates for Exchange Notes issued in exchange


                                      -11-

<PAGE>   12



therefor is to be issued (or any untendered principal amount of Old Notes to be
reissued) to the registered Holder, then such Holder need not and should not
endorse any tendered Old Notes, nor provide a separate bond power. In any other
case, such Holder must either properly endorse the Old Notes tendered or
transmit a properly completed separate bond power with this Letter of
Transmittal with the signatures on the endorsement or bond power guaranteed by
an Eligible Institution.

         If this Letter of Transmittal (or facsimile hereof) is signed by a
person other than the registered Holder or Holders of any Old Notes listed, such
Old Notes must be endorsed or accompanied by appropriate bond powers in each
case signed as the name of the registered Holder or Holders appears on the Old
Notes.

         If this Letter of Transmittal (or facsimile hereof) or any Old Notes or
bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, or officers of corporations or others acting in a fiduciary
or representative capacity, such persons should so indicate when signing, and
unless waived by the Company, evidence satisfactory to the Company of their
authority so to act must be submitted with this Letter of Transmittal.

         Endorsements on Old Notes or signatures on bond powers required by this
Instruction 6 must be guaranteed by an Eligible Institution.

         7. Special Registration and Delivery Instructions. Tendering Holders
should indicate, in the applicable box or boxes, the name and address to which
Exchange Notes or substitute Old Notes for principal amounts not tendered or not
accepted for exchange are to be issued or sent, if different from the name and
address of the person signing this Letter of Transmittal. In the case of
issuance in a different name, the taxpayer identification or social security
number of the person named must also be indicated.

         8. Backup Federal Income Tax Withholding and Substitute Form W-9. Under
the federal income tax laws, payments that may be made by the Company on account
of Exchange Notes issued pursuant to the Exchange Offer may be subject to backup
withholding at the rate of 31%. In order to avoid such backup withholding, each
tendering holder should complete and sign the Substitute Form W-9 included in
this Letter of Transmittal and either (a) provide the correct taxpayer
identification number ("TIN") and certify, under penalties of perjury, that the
TIN provided is correct and that (i) the holder has not been notified by the
Internal Revenue Service (the "IRS") that the holder is subject to backup
withholding as a result of failure to report all interest or dividends or (ii)
the IRS has notified the holder that the holder is no longer subject to backup
withholding; or (b) provide an adequate basis for exemption. If the tendering
holder has not been issued a TIN and has applied for one, or intends to apply
for one in the near future, such holder should write "Applied For" in the space
provided for the TIN in Part I of the Substitute Form W-9, sign and date the
Substitute Form W-9 and sign the Certificate of Payee Awaiting Taxpayer
Identification Number. If "Applied For" is written in Part I, the Company (or
the Paying Agent under the indenture governing the Exchange Notes) shall retain
31% of payments made to the tendering holder during the sixty-day period
following the date of the Substitute Form W-9. If the Holder furnishes the
Exchange Agent or the Company with its TIN within sixty days after the date of
the Substitute Form W-9, the Company (or the Paying Agent) shall remit such
amounts retained during the sixty-day period to the Holder and no further
amounts shall be retained or withheld from payments made to the Holder
thereafter. If, however, the Holder has not provided the Exchange Agent or the
Company with its TIN within such sixty-day period, the Company (or the Paying
Agent) shall remit such previously retained amounts to the IRS as backup
withholding. In general, if a Holder is an individual, the TIN is the Social
Security number of such individual. If the Exchange Agent or the Company are not
provided with the correct TIN, the Holder may be subject to a $50 penalty
imposed by the IRS. Certain Holders (including, among others, certain
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. In order for a foreign individual to
qualify as an exempt recipient, such Holder must submit a statement (generally,
IRS Form W-8), signed under penalties of perjury, attesting to that individual's
exempt status. Such statements can be obtained from the Exchange Agent. For
further information concerning backup withholding and instructions for
completing the Substitute Form W-9 (including how to obtain a taxpayer
identification number if you do not have one and how to complete the Substitute
Form W-9 if Old Notes are registered in more than one name), consult the
enclosed Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9.

<PAGE>   13




         Failure to complete the Substitute Form W-9 will not, by itself, cause
Old Notes to be deemed invalidly tendered, but may require the Company (or the
Paying Agent) to withhold 31% of the amount of any payments made on account of
the Exchange Notes. Backup withholding is not an additional federal income tax.
Rather, the federal income tax liability of a person subject to backup
withholding will be reduced by the amount of tax withheld. If backup withholding
results in an overpayment of taxes, a refund may be obtained from the IRS.

         9. Transfer Taxes. The Company will pay all transfer taxes, if any,
applicable to the exchange of Old Notes pursuant to the Exchange Offer. If,
however, certificates representing Exchange Notes or Old Notes for principal
amounts not tendered or accepted for exchange are to be delivered to, or are to
be registered in the name of, any person other than the registered holder of the
Old Notes tendered hereby, or if tendered Old Notes are registered in the name
of a person other than the person signing this Letter of Transmittal, or if a
transfer tax is imposed for any reason other than the exchange of Old Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered holder or on any other persons) will be
payable by the tendering Holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted with this Letter of Transmittal,
the amount of such transfer taxes will be billed directly to such tendering
Holder. See the Prospectus under "The Exchange Offer--Solicitation of Tenders;
Fees and Expenses."

         Except as provided in this Instruction 9, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes listed in this Letter of
Transmittal.

         10. Waiver of Conditions. The Company reserves the right, in their sole
discretion, to amend, waive or modify specified conditions in the Exchange Offer
in the case of any Old Notes tendered.

         11. Mutilated, Lost, Stolen or Destroyed Old Notes. Any tendering
Holder whose Old Notes have been mutilated, lost, stolen or destroyed should
contact the Exchange Agent at the address indicated herein for further
instructions.

         12. Requests for Assistance or Additional Copies. Requests for
assistance and requests for additional copies of the Prospectus or this Letter
of Transmittal may be directed to the Exchange Agent at the address specified in
the Prospectus. Holder may also contact their broker, dealer, commercial bank,
trust company or other nominee for assistance concerning the Exchange Offer.

</TABLE>


                            IMPORTANT TAX INFORMATION

         Under federal income tax laws, a Holder whose tendered Old Notes are
accepted for payment is required to provide the Exchange Agent (as payer) with
such Holder's correct TIN on Substitute Form W-9 below or otherwise establish a
basis for exemption from backup withholding. If such Holder is an individual,
the TIN is his social security number. If the Exchange Agent is not provided
with the correct TIN, a $50 penalty may be imposed by the IRS, and payments made
pursuant to the Exchange Offer may be subject to backup withholding.

         Certain Holders (including, among others, certain corporations and
certain foreign persons) are not subject to these backup withholding and
reporting requirements. Exempt Holders should indicate their exempt status on
Substitute Form W-9. A foreign person may qualify as an exempt recipient by
submitting to the Exchange Agent a properly completed IRS Form W-8, signed under
penalties of perjury, attesting to that Holder's exempt status. A Form W-8 can
be obtained from the Exchange Agent. See the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions.

         If backup withholding applies, the Exchange Agent is required to
withhold 31% of any payments made to the Holder or other payee. Backup
withholding is not an additional federal income tax. Rather, the federal income
tax liability of persons subject to backup withholding will be reduced by the
amount of tax withheld. If withholding results in an overpayment of taxes, a
refund may be obtained from the IRS.

PURPOSE OF SUBSTITUTE FORM W-9

         To prevent backup withholding on payments made with respect to the
Exchange Offer, the Holder is required to provide the Exchange Agent with
either: (i) the Holder's correct TIN by completing the Substitute Form W-9
below, certifying that the TIN provided on Substitute Form W-9 is correct (or
that such Holder is awaiting a TIN) and that (A) the Holder has not been
notified by the IRS that the Holder is subject to backup withholding as a result
of failure to report all interest or dividends or (B) the IRS has notified the
Holder that the Holder is no longer subject to backup withholding or (ii) an
adequate basis for exemption.

WHAT NUMBER TO GIVE THE EXCHANGE AGENT

         The Holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered Holder of
the Old Notes. If the Old Notes are held in more than one name or are held not
in the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional guidance on which number to report.

         CERTIFICATION OF PAYEE AWAITING TAXPAYER INDEMNIFICATION NUMBER

         I certify, under penalties of perjury, that a Taxpayer Identification
Number has not been issued to me, and that I mailed or delivered an application
to receive a Taxpayer Identification Number to the appropriate Internal Revenue
Service Center or Social Security Administration Office (or I intend to mail or
deliver an application in the near future). I understand that if I do not
provide a Taxpayer Identification Number to the payer, 31% of all payments made
to me on account of the Exchange Notes shall be retained until I provide a
Taxpayer Identification Number to the payer and that, if I do not provide my
Taxpayer Identification Number within sixty days, such retained amounts shall be
remitted to the Internal Revenue Service as backup withholding and 31% of all
reportable payments made to me thereafter will be withheld and remitted to the
Internal Revenue Service until I provide a Taxpayer Identification Number.

         The undersigned acknowledges receipt of the Prospectus and the related
Letter of Transmittal which describes the Company's offer (the "Exchange Offer")
to exchange $1,000 in principal amount of a new series of 115/8% Senior
Subordinated Notes due 2008, Series B (the "Exchange Notes") for each $1,000 in
principal amount of the Old Notes.

         The undersigned hereby tenders to the Company the aggregate principal
amount of Old Notes set forth below on the terms and conditions set forth in the
Prospectus and the related Letter of Transmittal pursuant to the guaranteed

Procedures" section in the Prospectus and the accompanying Letter of
Transmittal.

         The undersigned understands that no withdrawal of a tender of Old Notes
may be made on or after the expiration date of the Exchange Offer. The
undersigned understands that for a withdrawal of a tender of Old Notes to be

         The undersigned understands that the exchange of Old Notes for Exchange

Trust Company (the "Depositary" or "DTC")) and (ii) a Letter of Transmittal (or
facsimile thereof) with respect to such Old Notes, properly completed and duly
executed, with any required signature guarantees, this Notice of Guaranteed

To Our Clients:

         Enclosed for your consideration are the Prospectus dated __________,
1999 (the "Prospectus") and the related Letter of Transmittal (which together
with the Prospectus constitute the "Exchange Offer") in connection with the
offer by American Plumbing & Mechanical, Inc., a Delaware corporation (the
"Company"), to exchange its outstanding 115/8% Senior Subordinated Notes due
2008, Series A (the "Exchange Notes") for any and all of the outstanding 115/8%
Senior Subordinated Notes due 2008, Series B (the "Old Notes"), upon the terms
and subject to the conditions set forth in the Exchange Offer.

         We are the Registered Holders of Old Notes held for your account. An
exchange of the Old Notes can be made only by us as the Registered Holders and
pursuant to your instructions. The Letter of Transmittal is furnished to you for
your information only and cannot be used by you to exchange the Old Notes held
by us for your account. The Exchange Offer provides a procedure for holders to
tender by means of guaranteed delivery.

         We request information as to whether you wish us to exchange any or all
of the Old Notes held by us for your account upon the terms and subject to the
conditions of the Exchange Offer.

         Your attention is directed to the following:

              1. The Exchange Notes will be exchanged for the Old Notes at the
         rate of $1,000 principal amount of Exchange Notes for each $1,000
         principal amount of Old Notes. Interest on the Notes will accrue at the
         rate of 115/8% per annum and will be payable semi-annually on each
         April 15 and October 15 commencing October 15, 1999, to the holders of
         record of Notes at the close of business on the April 1 and October 1,
         respectively, immediately preceding such interest payment date.
         Interest on the Notes will accrue from the most recent date to which
         interest has been paid or, if no interest has been paid, from the
         original date of issuance. Interest will be computed on the basis of a
         360-day year comprised of twelve 30-day months. The form and terms of
         the Exchange Notes are identical in all material respects to the form
         and terms of the Old Notes, except that (i) the offering of the
         Exchange Notes has been registered under the Securities Act of 1933, as
         amended (the "Securities Act"), (ii) the Exchange Notes will not be
         subject to transfer restrictions and (iii) certain provisions relating
         to an increase in the stated interest rate on the Old Notes provided
         for under certain circumstances will be eliminated.

              2. Based on an interpretation by the staff of the Securities and
         Exchange Commission, Exchange Notes issued pursuant to the Exchange
         Offer in exchange for Old Notes may be offered for resale, resold and
         otherwise transferred by holders thereof (other than any such holder
         which is an "affiliate" of the Company within the meaning of Rule 405
         under the Securities Act or a "broker" or "dealer" registered under the
         Securities Exchange Act of 1934, as amended) without compliance with
         the registration and prospectus delivery provisions of the Securities
         Act, provided that such Exchange Notes are acquired in the ordinary
         course of such holders' business and such holders have no arrangement
         or understanding with any person to participate in the distribution of
         such Exchange Notes. See the discussion in the Prospectus under "The
         Exchange Offer--Purpose and Effect of the Exchange Offer."

              3. The Exchange Offer is not conditioned on any minimum principal
         amount of Old Notes being tendered.

              4. Notwithstanding any other term of the Exchange Offer, the
         Company will not be required to accept for exchange, or exchange
         Exchange Notes for, any Old Notes not theretofore accepted for
         exchange, and may terminate or amend the Exchange Offer as provided
         herein before the acceptance of such Old Notes, if any of the
         conditions described in the Prospectus under "The Exchange
         Offer--Conditions to the Exchange Offer" exist.

              5. Tendered Old Notes may be withdrawn at any time prior to
         5:00 p.m., New York City time, on , 1999.

              6. Any transfer taxes applicable to the exchange of the Old Notes

         provided in the Prospectus under "The Exchange Offer--Solicitation of
         Tenders; Fees and Expenses" and in Instruction 9 of the Letter of
         Transmittal.

         If you wish to have us tender any or all of your Old Notes, please so
instruct us by completing, detaching and returning to us the instruction form
attached hereto. An envelope to return your instructions is enclosed. If you
authorize a tender of your Old Notes, the entire principal amount of Old Notes
held for your account will be tendered unless otherwise specified on the
instruction form. Your instructions should be forwarded to us in ample time to
permit us to submit a tender on your behalf by the Expiration Date.

         The Exchange Offer is not being made to, nor will tenders be accepted
from or on behalf of, holders of the Old Notes in any jurisdiction in which the
making of the Exchange Offer or acceptance thereof would not be in compliance
with the laws of such jurisdiction or would otherwise not be in compliance with
