ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS

         (a) Financial Statements of Businesses Acquired


               REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To Lindy Dennis Industries, Inc. and Affiliates:

We have audited the accompanying combined balance sheet of Lindy Dennis
Industries, Inc. and Affiliates as of December 31, 1999, and the related
combined statements of income, cash flows and stockholders' equity for the year
then ended. 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 audit.

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

In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of Lindy Dennis
Industries, Inc. and Affiliates as of December 31, 1999, and the results of
their operations and their cash flows for the year then ended, in conformity
with accounting principles generally accepted in the United States.

                   LINDY DENNIS INDUSTRIES, INC. AND AFFILIATES

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

         Lindy Dennis Industries, Inc., a Texas corporation, together with LDI
Heating and Air Conditioning and LDI Mechanical, both California corporations,
and Krahenbuhl Plumbing, Inc., Krahenbuhl Fire Sprinklers, LLC and Green Valley
Plumbing, Inc., Nevada corporations, (the "Combined Companies") are commonly
owned and managed, and all transactions within the Combined Companies have been
eliminated in consolidation. Unless distinction is necessary, the Combined
Companies shall be referred to herein as the "Company". The Company operates
primarily as a heating, ventilation and air conditioning ("HVAC") contractor
specializing in the multifamily residential market in California and Nevada. The
Company performs the majority of its contract work under fixed price
arrangements with contract terms generally ranging from six to twelve months.

         In March 1999, the sole stockholder of Lindy Dennis Industries, Inc.
acquired a 35 percent interest in Krahenbuhl Plumbing, Inc., Krahenbuhl Fire
Sprinklers, LLC and Green Valley Plumbing, Inc. from an existing stockholder of
the companies.

         On March 1, 2000, American Plumbing and Mechanical, Inc. (AMPAM),
acquired all outstanding shares of the Company's common stock in exchange for
cash and shares of AMPAM common stock(See Note 11).

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

         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.

         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 improvements 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 income.

         Revenue Recognition

         The Company recognizes revenue from construction contracts on the
percentage-of-completion method measured by the percentage of cost incurred 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





                                       6
<PAGE>   8


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. Revenues from
services are recognized when services are performed.

         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 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 accounts.

         Income Taxes

         All of the Combined Companies with the exception of Lindy Dennis
Industries, Inc. and Krahenbuhl Fire Sprinklers, LLC have elected S Corporation
status, as defined by the Internal Revenue Code. Once S Corporation status is
elected, a company itself is not subject to taxation for federal purposes,
rather, its 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 taxes consists only of state income taxes for the
Combined Companies that have elected S Corporation status and both federal and
state taxes for Lindy Dennis Industries, Inc. which is a C Corporation.

         The Company follows the liability method of accounting for income taxes
for those companies recording 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 principles
generally accepted accounting United States 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. Reference is
made to the "Revenue Recognition" section of this note for discussion of some of
the significant estimates reflected in the Company's financial statements.

         Realization of Long-Lived Assets

         In the event that facts and circumstances indicate that property and
equipment or other long-lived assets may be impaired, an evaluation of
recoverability will be performed. The result of any impairment would be to
expense the difference between the fair value of such property and its carrying
value. No such impairment had occurred at December 31, 1999.

         Fair Value of Financial Instruments

         The carrying amounts reflected in the accompanying balance sheet for
cash, accounts receivable, costs and estimated earnings in excess of billings on
uncompleted contracts, accounts payable and accrued expenses, accounts
payable-related parties, and billings in excess of costs and estimated earnings
on uncompleted contracts and the credit facility approximate fair value due to
the short term nature of the instruments.

Company's financial position or result 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.

11. MAJOR CUSTOMERS AND RISK CONCENTRATION:

         The Company had no customers whose sales exceeded 10 percent of total
revenues during the year ended December 31, 1999.

         In general, the Company performs its services under contract terms that
entitle it to progress payments, and is typically, by law, granted a lien
interest on the work until paid. The Company is exposed to potential credit
risks related to changes in business and economic factors. However, management
believes that its contract acceptance, billing, and collection policies are
adequate to minimize the potential credit risks.

         Additionally, 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.

12. SUBSEQUENT EVENTS:

         On March 1, 2000, AMPAM acquired through merger, all of the stock of
the Company in exchange for cash and AMPAM's common stock. AMPAM also negotiated
and entered into certain leases with the Company's former stockholders relating
to the land and buildings from which the Company operates. The Company is now a
wholly owned subsidiary of AMPAM.

            AMERICAN PLUMBING AND MECHANICAL, INC. AND SUBSIDIARIES

                    PRO FORMA CONDENSED FINANCIAL STATEMENTS

                                   (Unaudited)

                    (In Thousands, Except Per Share Amounts)


American Plumbing and Mechanical, Inc., a Delaware corporation, (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
residential and commercial/institutional markets. On April 1, 1999, the Company
acquired ten U.S. businesses (the "Founding Companies") and completed the
initial financings. Subsequently, the Company acquired the outstanding stock of
two additional companies and the assets of a third company (the "Subsequent
Acquisitions").

On March 1, 2000, the Company acquired all the stock of Lindy Dennis Industries,
Inc. and Affiliates ("LDI"), which includes Lindy Dennis Industries, Inc., a
Texas Corporation, together with LDI Heating and Air Conditioning and LDI
Mechanical, both California corporations, and Krahenbuhl Plumbing, Inc.,
Krahenbuhl Fire Sprinklers, LLC and Green Valley Plumbing, Inc., Nevada
corporations, through the issuance of 1,346,154 shares of the Company's common
stock and cash consideration of approximately $12 million. The cash
consideration was provided by the Company's credit facility. The purchase was
accounted for under the purchase method of accounting and LDI is considered a
significant subsidiary pursuant to the rules of the Securities and Exchange
Commission.

The following unaudited pro forma combined statements of operations present the
Company, restated for the Founding Companies, the Subsequent Acquisitions and
LDI as if the acquisitions by the Company occurred on January 1, 1999.
Statements of operations are provided for the year ended December 31, 1999 and
for the Company's most recent interim period ended March 31, 2000. The balance
sheet as of the most recent interim date can be found in the Company's quarterly
report on Form 10-Q for the quarterly period March 31, 2000.

The pro forma adjustments are based upon preliminary estimates, available
information and certain assumptions that management deemed appropriate. Final
purchase accounting adjustments will be made on the basis of appraisals and
evaluations and, therefore, may differ from the pro forma adjustments presented
herein. These pro forma financial statements should be read in conjunction with
the historical financial statements and notes thereto for the fiscal year ended
December 31, 1999, included in the Company's Form 10-K and the Company's
quarterly report on Form 10-Q for the quarterly period ended March 31, 2000. The
pro forma condensed statements of operations are not necessarily indicative of
what actual results of operations would have been had the transaction occurred
at the beginning of the periods presented nor does it purport to indicate the
results of future operations of the Company.

the stockholders and/or members of the Company (together, the "Company
Stockholders").

                                    RECITALS:

         WHEREAS, the Boards of Directors of AMPAM and the Company have
determined that the combination of AMPAM and the Company is in the best
interests of the stockholders and/or members of AMPAM and the Company,
respectively;

         WHEREAS, the Company Stockholders desire to convey to AMPAM all of the
issued and outstanding shares of capital stock and membership interest of the
Company, free and clear of all liens, and the Company Stockholders agree to be
bound by a covenant not to compete;

         WHEREAS, AMPAM desires to acquire such shares of capital stock and
membership interest of the Company as more fully set forth herein and enforce
the covenant not to compete; and

         WHEREAS, AMPAM, the Company and the Company Stockholders intend the
combination of AMPAM and the Company to qualify as a tax-free reorganization
under the provisions of Section 368 of the Internal Revenue Code of 1986, as
amended (the "Code"), and the regulations thereunder;

         NOW, THEREFORE, in consideration of the mutual covenants and agreements

                                    ARTICLE I

                                   THE MERGER

     SECTION 1.1. THE MERGER. (a) Subject to the execution of this Agreement and
the delivery of the documents listed in Section 1.7, at the Effective Time (as
hereinafter defined), the Company shall be merged (the "Merger") with and into
Acquisition in accordance with the General




                                     - 1 -

<PAGE>   8

Corporation Law of the State of Delaware ("Delaware Law") and the laws of the
states of organization of the Company (collectively "Company Law"), whereupon
the separate existence of the Company shall cease, and Acquisition shall be the
surviving corporation (the "Surviving Corporation").

         (b) Immediately following the execution of this Agreement and the
delivery of the documents listed in Section 1.7, and the satisfaction or waiver
of the conditions contained in Section 1.8 and Section 1.9, the Company and
Acquisition will file a certificate of merger with the Delaware Secretary of
State (the "Certificate of Merger") and appropriate merger documents with the
Texas, California and Nevada Secretary of State (the "State Certificates"), and
make all other filings or recordings required by Delaware Law or Company Law in
connection with the Merger. The Merger shall become effective at such time (the
"Effective Time") as the Certificate of Merger and the State Certificates are
duly filed with the Delaware, Texas, California and Nevada Secretary of State
(or at such later time as may be agreed in writing by the parties hereto and
specified in the Certificate of Merger and the State Certificates).

         (c) From and after the Effective Time, the Surviving Corporation shall
possess all the rights, assets, powers, privileges, and franchises and be
subject to all of the obligations, liabilities, restrictions, and disabilities
of the Company and Acquisition, all as provided under Delaware Law.

         (d) The closing of the transactions contemplated by this Agreement (the
"Closing") shall take place at the offices of Andrews & Kurth, L.L.P. in
Houston, Texas, at 10:00 a.m., on a day within 5 business days following the
date on which regulatory approval under the Hart Scott Act (as defined) is
received or on such other day and time as shall be agreed to by the parties.
This Closing shall coincide with the Effective Time.

     SECTION 1.2. CONVERSION OF SHARES. At the Effective Time:

         (a) the shares of common stock of the Company ("Company Common Stock")
and membership interest of the Company ("Company Membership Interest")
outstanding immediately prior to the Effective Time (the Company Common Stock
and the Company Membership Interest outstanding immediately prior to the
Effective Time shall hereinafter be referred to collectively as the "Company
Stock" unless some distinction is necessary) shall be converted into the right
to receive, without interest, an aggregate consideration equal to 1,346,154
shares of common stock, $0.01 par value, of AMPAM ("AMPAM Common Stock") and
$12,000,000 in cash, as adjusted by Section 1.3 (collectively, the "Merger
Consideration").

         (b) each share of common stock of Acquisition outstanding immediately
prior to the Effective Time shall remain outstanding and represent, after the
Effective Time, one share of common stock of the Surviving Corporation, and
shall constitute the only outstanding shares of capital stock of the Surviving
Corporation.





                                     - 2 -

         (c) AMPAM shall issue to non-stockholder employees of the Company, as
determined by the Company and approved by AMPAM, 195,000 non-qualified stock
options, at an option price per share to be determined by AMPAM within thirty
(30) days after the Effective Time, which will vest 20% per year over a five
year period beginning on the date of such grant.

     SECTION 1.3. MERGER CONSIDERATION ADJUSTMENT.

         (a) Within three (3) days before the anticipated date of Closing, the
Company Stockholders will cause the Company to prepare an estimated balance
sheet of the Company (the "Estimated Balance Sheet") at the Company's expense
which will be dated as of the Effective Time (as defined in Section 12.15) and
will deliver such Estimated Balance Sheet to AMPAM for its review. The cash
portion only of the Merger Consideration set forth in Section 1.2 hereof to be
paid on the date of Closing shall then be adjusted (the "Adjustments") as
follows (the "Adjusted Merger Consideration"):

               (i) increased by the amount, if any, by which the Actual Working
          Capital (as defined in Section 12.15) as reflected on the Estimated
          Balance Sheet exceeds the Target Working Capital (as defined in
          Section 12.15);

               (ii) reduced by the amount, if any, by which the Target Working
          Capital exceeds the Actual Working Capital as reflected on the
          Estimated Balance Sheet; and

               (iii) reduced by the amount, if any, of Actual Indebtedness (as
          defined in Section 12.15) (except for any Actual Indebtedness used in
          the calculation of Actual Working Capital), as reflected on the
          Estimated Balance Sheet.

         (b) Within the sixty (60) day period following the Closing, AMPAM and
the Company Stockholders will attempt in good faith to finalize the Company's
Estimated Balance Sheet, such finalized balance sheet to be referred to herein
as the "Final Balance Sheet". If AMPAM and the Company Stockholders cannot
mutually agree on a Final Balance Sheet within this sixty (60) day period, then
immediately following the conclusion of such sixty (60) day period the Final
Balance Sheet shall be delivered to the independent accounting firm of
Pricewaterhouse Coopers. Pricewaterhouse Coopers shall have thirty (30) days to
review the Final Balance Sheet and its determinations within such period shall
be final and binding on the parties. To the extent the Final Balance Sheet
differs from the Estimated Balance Sheet and to the extent these differences
would increase or decrease the Adjustments as calculated pursuant to Section
1.3(a), the cash portion only of the Adjusted Merger Consideration shall then be
further adjusted (the "Readjusted Merger Consideration") in the same manner as
the formula used in Section 1.3(a).

         (c) The settlement or payment of the Adjustments to the cash portion
only of the Merger Consideration pursuant to Section 1.3(a) shall occur on the
date of Closing. The settlement








                                     - 3 -

or payment of the Adjustments to the cash portion of the Adjusted Merger
Consideration pursuant to Section 1.3(b) shall occur within ten (10) business
days after the Final Balance Sheet is finalized.

     SECTION 1.4. SURRENDER AND PAYMENT. At the Effective Time, the Company
Stockholders will deliver to AMPAM the certificates listed on Schedule 3.2 (the
"Certificates") representing all of the outstanding shares of Company Stock, and
AMPAM will, in exchange therefor, issue and deliver to the Company Stockholders
the AMPAM Common Stock, and pay to the Company Stockholders by wire transfer in
immediately available funds the Adjusted Merger Consideration (subject to
further readjustment, if necessary, to arrive at the Readjusted Merger
Consideration), divided among the Company Stockholders in accordance with the
written instructions provided in Schedule 3.2. The Certificates will be duly
endorsed (or accompanied by duly executed stock powers), with signatures of
those Company Stockholders not present at the closing guaranteed by a commercial
bank.

     SECTION 1.5. WITHHOLDING RIGHTS. Each of the Surviving Corporation and
AMPAM shall be entitled to deduct and withhold from the consideration otherwise
payable to any Person (as defined in Section 12.15) pursuant to this Article I
such amounts as it is required to deduct and withhold with respect to the making
of such payment under any provision of federal, state, local, or foreign tax
law. These amounts are set forth in Schedule 1.5 to this Agreement. To the
extent that amounts are so withheld by the Surviving Corporation or AMPAM, as
the case may be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Company Stock in respect of
which such deduction and withholding was made by the Surviving Corporation or
AMPAM, as the case may be.

     SECTION 1.6. LOST CERTIFICATES. If any Certificate shall have been lost,
stolen, or destroyed, upon the making of an affidavit of that fact by the Person
claiming such Certificate to be lost, stolen, or destroyed and, if required by
the Surviving Corporation, the posting by such Person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such Certificate, AMPAM
will issue in exchange for such lost, stolen, or destroyed Certificate, the
Merger Consideration to be paid in respect of the shares of Company Stock
represented by such Certificates as contemplated by this Article I.

     SECTION 1.7. OTHER DOCUMENTS TO BE DELIVERED IMMEDIATELY PRIOR TO THE

               (i) by mutual consent of AMPAM and the Company Stockholders;

               (ii) by all of the Company Stockholders on the one hand, or by
          AMPAM (acting through its board of directors), on the other hand, if
          the transactions contemplated by this Agreement to take place at the
          Closing shall not have been consummated by March 31, 2000, unless the
          failure of such transactions to be consummated is due to the willful
          failure of the party seeking to terminate this Agreement to perform
          any of its obligations under this Agreement to the extent required to
          be performed by it prior to the Closing. Additionally, if the reason
          for the failure of the Closing to occur by this date is that
          regulatory approval under the Hart Scott Act has not been received in
          time for the Closing to occur by March 31, 2000, then, the Closing may
          be extended by the mutual agreement of the parties to a date five days
          after such regulatory approval is received;

               (iii) by the Company Stockholders on the one hand, or by AMPAM,
          on the other hand, if a material breach or material default shall be
          made by the other party in the observance or in the due and timely
          performance of any of the covenants or agreements contained herein,
          and the curing or waiver of such material breach or material default
          shall not have been made on or before the Closing;

               (iv) by either party if, pursuant to Section 5.16, that party
          wishes to amend their Schedules and the other party refuses to consent
          to such amendment;

               (v) by the Company Stockholders, if the conditions set forth in
          Section 1.8 hereof have not been satisfied or waived as of the
          Closing; or

               (vi) by AMPAM, if the conditions set forth in Section 1.9 hereof
          have not been satisfied or waived as of the Closing.

         (b) Procedure and Effect of Termination. In the event of a termination
pursuant to this Section 1.10, written notice setting forth the reasons thereof
shall forthwith be given by the terminating party to the other party. If this
Agreement is terminated as provided in this Section 1.10, no party shall have
any liability or further obligation hereunder to any other party, except as
provided








                                     - 7 -
<PAGE>   14

in Article X, 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.

property or the conduct of its business and operations makes such qualification

qualified is not reasonably expected to have, individually or in the aggregate,
a Company Material Adverse Effect (as defined in Section 12.15). Schedule 3.1

Stockholders and constitutes the valid and binding obligation of the Company and

         The Company Stockholders and AMPAM each make the following covenants:

SECTION 6.1. INDEMNIFICATION BY THE COMPANY STOCKHOLDERS. (a) The Company

indemnify, defend, protect, and hold harmless AMPAM, the Company, and the
Surviving Corporation, and their respective officers, directors, employees,
stockholders, agents, representatives, and Affiliates (the "AMPAM





                                     - 28 -

Indemnitees") at all times from and after the date of this Agreement until the
applicable Expiration Date from and against all claims, damages, losses,
liabilities (joint or several), obligations, penalties, defenses, actions,
lawsuits, proceedings, judgments, demands, assessments, adjustments, costs, and
expenses (including specifically, but without limitation, reasonable fees,
disbursements, and expenses of attorneys, accountants, other professional
advisors and of expert witnesses and reasonable costs of investigation and
preparation) (collectively "Damages"), as they are incurred, directly or
indirectly resulting from, relating to or arising out of (i) any breach of or
inaccuracy in, or any allegation or claim by a third party which, if true, would
constitute a breach or inaccuracy in, any representation or warranty set forth
herein or in the Schedules or certificates delivered in connection herewith;
(ii) any breach or non-performance, partial or total, by the Company or any of
the Company Stockholders of any covenant or agreement of the Company (or any

     (b) AMPAM acknowledges and agrees that other than the representations and
warranties of the Company Stockholders specifically contained in this Agreement,

Agreement, the Company, or the Company's assets, liabilities or business.

     SECTION 6.2. INDEMNIFICATION RELATED TO TAX LIABILITIES. The Company
Stockholders shall retain liability, and shall indemnify AMPAM, for the payment
of any Tax liabilities, net of any Tax benefits, with respect to the conduct of
the business of the Company prior to and up to the Effective Time.

     SECTION 6.3. INDEMNIFICATION RELATED TO ACCOUNTS RECEIVABLE. Should the
Company Stockholders indemnify AMPAM for a breach of the representation and
warranty contained in Section 3.8 related to collectibility of accounts
receivable, AMPAM shall pay to the Company Stockholders any net amounts after
attorney fees that are received by the Surviving Corporation or AMPAM after the
Company Stockholders make such indemnification payments with respect to accounts
receivable outstanding on the Company Unaudited Balance Sheet Date. The Company
Stockholders may pursue the collection of such accounts receivable at their own
cost and for their own account if the Board of Directors of the Surviving
Corporation elects not to pursue the collection of such accounts receivable.

     SECTION 6.4. INDEMNIFICATION BY AMPAM. AMPAM covenants and agrees that it

                                     - 29 -
<PAGE>   36


other professional advisors and of expert witnesses and costs of investigation
and preparation), as they are incurred, directly or indirectly resulting from,
relating to or arising out of:

               (i) any breach of or any inaccuracy in, or any claim by a third
          party which, if true, would constitute a breach or inaccuracy in, any
          representation or warranty of AMPAM set forth herein or in the
          Schedules or certificates delivered in connection herewith;

               (ii) any breach or non-performance, partial or total, by AMPAM of
          any covenant or agreement of AMPAM (or any Affiliate or subsidiary
          thereof) contained in 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 on any untrue statement or alleged untrue statement of a
          material fact contained in the PPM, or any amendment of or supplement
          to the PPM, or arising out of or based on 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.

     SECTION 6.5. INDEMNIFICATION PROCEEDINGS. Promptly after a party
indemnified pursuant to this Article VI ("Indemnitee") has received notice of or
has Knowledge of any claim by a person not a party to this Agreement ("third
party") or the commencement of any action or proceeding by a third party, the
Indemnitee shall promptly, and in any event within 60 days of the assertion of
any claim or the discovery of any fact upon which Indemnitee intends to base a
claim for indemnification under this Agreement ("Indemnitee Claim"), as a
condition precedent to the Indemnitee Claim, give written notice to the party or
parties from whom indemnification is sought ("Indemnitor") of such claim by the
third party. Such notice shall state the nature and the basis of such claim and
a reasonable estimate of the amount thereof. If the Indemnitor does not object
in writing to such indemnification claim within 30 days after receiving notice
thereof, the Indemnitee shall be entitled to recover promptly from the
Indemnitor the amount of such claim (but such recovery shall not limit the
amount of any additional indemnification to which the Indemnitee may be entitled
pursuant to Section 6.1 or 6.3, as the case may be), and no later objection by
the Indemnitor shall be permitted. If the Indemnitor agrees that he, she or it
has an indemnification obligation but objects that he, she or it is obligated to
pay only a lesser amount, the Indemnitee shall nevertheless be entitled to
recover promptly from the Indemnitor the lesser amount, without prejudice to the
Indemnitee's claim for the difference. In the event of any Indemnitee Claim,
Indemnitor, at its option, shall have the right to defend or settle, at its own
expense and by its own counsel, any such matter so long as the Indemnitor
pursues the same in good faith and diligently. If the Indemnitor undertakes to
defend or settle, it shall promptly notify the Indemnitee of its intention to do
so, within the Indemnitor's 30-day objection period set forth above, and the
Indemnitee shall cooperate with the Indemnitor and its counsel in the defense
thereof and in any settlement thereof. Notwithstanding the foregoing, the
Indemnitee shall have the right to participate in any matter through counsel of
its own choosing at Indemnitor's own expense; provided that the Indemnitor's
counsel shall always be lead counsel and





                                     - 30 -
<PAGE>   37


shall determine all litigation and settlement steps, strategy and the like.
Except as set forth in the preceding sentence, after the Indemnitor has notified
the Indemnitee of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnitor diligently pursues such
defense, the Indemnitor shall not be liable for any additional legal expenses
incurred by the Indemnitee in connection with any defense or settlement of such
asserted liability, except to the extent such participation is requested by the
Indemnitor, in which event the Indemnitee shall be reimbursed by the Indemnitor
for reasonable additional legal expenses, out-of-pocket expenses and allocable
share of employee compensation incurred in connection with such participation
for any employee whose participation is so requested. If the Indemnitor desires
to accept a final and complete settlement of any such third party claim and the
Indemnitee refuses to consent to any such settlement which contains a complete
and irrevocable release of Indemnitee of all current and future claims related
to or arising out of the matter in dispute, then the Indemnitor's liability
under this Section with respect to such third party claim shall be limited to
the amount so offered in settlement by said third party. If the Indemnitor does
not undertake to defend such matter to which the Indemnitee is entitled to
indemnification hereunder, or fails diligently to pursue such defense, the
Indemnitee may undertake such defense through counsel of its choice, at the cost
and expense of the Indemnitor, and the Indemnitee may settle such matter,
without the consent of the Indemnitor, and the Indemnitor shall immediately
reimburse the Indemnitee for the amount paid in such settlement and any other
liabilities or expenses incurred (including all legal fees and expenses) by the
Indemnitee in connection therewith as such amounts, liabilities, expenses and
fees are incurred. In the event that the Indemnitee does not elect to defend
such matter to which the Indemnitee is entitled to indemnification hereunder,
then any failure of the Indemnitee to defend or to participate in the defense of
such matter, shall not relieve the Indemnitor of its obligations hereunder.

     SECTION 6.6. EXCLUSIVE REMEDY. The indemnification provided for in this
Article VI 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 of the Company Stockholders 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 Article VI shall be treated as an adjustment to the Merger
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 Indemnitee
or any of its Affiliate causes any such payment not to be treated as an
adjustment to the Merger Consideration for U.S. Federal income Tax purposes.

     SECTION 6.7. LIMITATIONS ON INDEMNIFICATION. (a) AMPAM shall not assert any
claim for indemnification under this Article VI against the Company Stockholders
until such time as, and solely to the extent that, the aggregate of all claims
which AMPAM may have against the Company





                                     - 31 -
<PAGE>   38


Stockholders shall exceed 3.0% of the Merger Consideration (the "Indemnification
Threshold"). The Company 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 Company Stockholders may have
against AMPAM shall exceed the Indemnification Threshold; provided, however,
that this sentence shall not be applicable with respect of any failure by AMPAM
to comply with its obligations pursuant to Section 1.2, Section 1.3 and Section
5.6. After the Indemnification Threshold 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.

     (b) No person shall be entitled to indemnification under this Article VI 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 Company Stockholders shall limit, diminish or change
any obligation of AMPAM pursuant to Section 5.6 hereof.

     (c) Notwithstanding any other term of this Agreement, no Company
Stockholder shall be liable under this Article VI for an amount which exceeds
eighty-five percent (85%) of the amount of proceeds received by such Company
Stockholder (valued as of the Closing) in connection with the purchase and sale
of the Company Stock.

     (d) A Company Stockholder may pay any indemnification obligation under
Article VI by means of the payment of cash or a combination of the payment of
cash and the delivery to AMPAM of shares of AMPAM stock; provided that AMPAM
shall have the right to reduce pro rata the number of shares of each Company
Stockholder included in the payment of such indemnification obligation to the
extent that inclusion of such shares would, in the written opinion of tax
counsel to AMPAM or its independent auditors, cause the transactions
contemplated hereby to fail as a 368 Reorganization. For the purpose of
crediting Company 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 any
party for such loss, liability or expense (or, in the case of AMPAM, by AMPAM,
Acquisition or any subsidiary of AMPAM or Acquisition) 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.

     SECTION 6.8. INDEMNIFICATION IF NEGLIGENCE OF INDEMNITEE. The
indemnification provided in this Article VI shall be applicable whether or not
negligence of the Indemnitee is alleged or proven.

     SECTION 6.9. NO THIRD PARTY BENEFICIARIES. The foregoing indemnification is
given solely for the purpose of protecting the AMPAM Indemnitees and the
Stockholder Indemnitees and shall not be deemed extended to, or interpreted in a
manner to confer any benefit, right, or cause of action upon, any other Person.


                                   ARTICLE VII

                            NONCOMPETITION COVENANTS

     SECTION 7.1. PROHIBITED ACTIVITIES. Except as otherwise provided in the
Employment Agreements, the Company Stockholders will not, during the term of
their employment with the Surviving Corporation and for a period of two (2)
years immediately following the termination of a Stockholder's employment with
the Surviving Corporation or AMPAM, directly or indirectly, for themselves or on
behalf of or in conjunction with any Person:

     (a) engage, as an officer, director, shareholder, owner, partner, joint
venturer, or in a managerial or advisory 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
directly related thereto (such business and operations referred to herein as the
"Plumbing and Mechanical Business"), in direct competition with AMPAM or any of
its subsidiaries within 100 miles of where AMPAM or any of its subsidiaries
conducts business, including any territory serviced by AMPAM or any of its
subsidiaries (which subsidiaries, for purposes of this Article VII shall
include, without limitation, the Surviving Corporation) (the "Territory");

     (b) call upon any Person who is, at that time, within the Territory, an
employee of AMPAM or any of its subsidiaries for the purpose or with the intent
of enticing such employee away from or out of the employ of AMPAM or any of its
subsidiaries;

     (c) call upon any Person who is, at that time, or which has been, within
one (1) year prior to that time, a customer of AMPAM or any of its subsidiaries
within the Territory for the purpose of soliciting customers, orders or
contracts for any Plumbing and Mechanical Business within the Territory;

     (d) call upon any prospective acquisition candidate, on any Company
Stockholder's own behalf or on behalf of any competitor of AMPAM or any of its
subsidiaries, which candidate, to the Knowledge of such Stockholder after due
inquiry, was called upon by AMPAM or any subsidiary




                                     - 33 -
<PAGE>   40


thereof or for which AMPAM or any subsidiary thereof made an acquisition
analysis, for the purpose of acquiring such entity; or

     (e) disclose customers, whether in existence or proposed, of AMPAM or any
of its subsidiaries to any person, firm, partnership, corporation or business
for any reason or purpose whatsoever except to the extent that AMPAM or any of
its subsidiaries has in the past disclosed such information to the public, any
person, firm partnership, corporation, business or other entity for valid
business reasons.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Company Stockholder from (i) acquiring as an investment not more
than one percent (1%) of the capital stock of a company engaged in the Plumbing
and Mechanical Business whose stock is publicly traded on a national securities
exchange, the NASDAQ Stock Market or an over-the-counter or similar market, (ii)
acquiring as an investment not more than one percent (1%) of the capital stock
of a competing business whose stock is not publicly traded if the AMPAM Board of
Directors consents to such acquisition, or (iii) engaging in activities,
directly or indirectly, related to owning, leasing, developing, or selling real
estate. Any ownership interest in any business which is in competition with
AMPAM or any of its subsidiaries shall immediately be disclosed to the AMPAM
Board of Directors.

     SECTION 7.2. EQUITABLE RELIEF. 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 Company Stockholder
agrees that the foregoing covenants may be enforced by AMPAM by injunctions,
restraining orders, and other equitable actions and agrees to waive any
requirement for the securing or posting of any bond in connection with the
obtaining of any such injunctive or any other equitable relief.

     SECTION 7.3. REASONABLE RESTRAINT. It is agreed by the parties hereto that
the foregoing covenants in this Article VII impose a reasonable restraint on the
Company Stockholders in light of the activities and business of AMPAM and its
subsidiaries on the date of the execution of this Agreement and the current
plans of AMPAM and its subsidiaries; but it is also the intent of AMPAM and the
Company Stockholders that such covenants be construed and enforced in accordance
with the changing activities, business, and locations of AMPAM and its
subsidiaries throughout the term of this covenant whether before or after the
Effective Time, unless the Company Stockholder was conducting such new business
prior to AMPAM or any of its subsidiaries conducting such new business. For
example, if, subsequent to the Effective Time or during the term of the Company
Stockholder's employment with the Surviving Corporation, as applicable, AMPAM or
one of its subsidiaries engages in new and different activities, enters a new
business, or establishes new locations for its current or new activities or
business in addition to or other than the activities or business it is currently
conducting in the locations currently established therefor, then the Company
Stockholders will be precluded from soliciting the customers or employees of
such new activities





                                     - 34 -
<PAGE>   41


or business or from such new location and from directly competing with such new
activities or business within 100 miles of where such new activities, business
or locations are conducted, unless the Company Stockholder was conducting such
new activities or business prior to AMPAM or any of its subsidiaries conducting
such new activities or business.

     SECTION 7.4. SEVERABILITY; REFORMATION. The covenants in this Article VII
are severable and separate, and the unenforceability of any specific covenant
shall not affect the continuing validity and enforceability of any other
covenant. In the event any court of competent jurisdiction shall determine that
the scope, time or territorial restrictions set forth in this Article VII 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 this
Agreement shall thereby be reformed.

     SECTION 7.5. MATERIAL AND INDEPENDENT COVENANT. The Company Stockholders
acknowledge that their agreements with the covenants set forth in this Article
VII are material conditions to AMPAM's agreement to execute and deliver this
Agreement and to consummate the transactions contemplated hereby. All of the
covenants in this Article VII 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 Company Stockholder against AMPAM or one of its subsidiaries,
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 two (2) year period during which the agreements and covenants of each
Company Stockholder made in this Article VII shall survive shall be computed by
excluding from such computation any time during which such Company Stockholder
is in violation of any provision of this Article VII. The covenants contained in
this Article VII shall not be affected by any breach of any other provision
hereof by any party hereto.

     SECTION 7.6. MATERIALITY. The Company and the Company Stockholders hereby
agree that this covenant is a material and substantial part of this transaction.

                                  ARTICLE VIII

                APPLICABLE SECURITIES LAWS/TRANSFER RESTRICTIONS

     SECTION 8.1. COMPANY STOCKHOLDERS' REPRESENTATIONS AND WARRANTIES
CONCERNING SECURITIES. As of the date hereof and as of the Effective Time, the
Company Stockholders hereby make the following representations and warranties to
and for the benefit of AMPAM: (i) that the Company Stockholders have been
provided with copies of the PPM and have been provided as much time and
opportunity as they deemed appropriate to review and study such PPM, and to
consult with AMPAM regarding the merits and risks of the transactions
contemplated by this Agreement; (ii) that the Company Stockholders have had
adequate opportunity to ask questions of and receive answers from the officers
of AMPAM pertaining to the purchase of the AMPAM Common Stock pursuant to the
Merger, and (iii) all such questions have been answered to the satisfaction of
the Company Stockholders.

     SECTION 8.2. TRANSFER RESTRICTIONS RELATING TO AMPAM COMMON STOCK. For a
period of two years from the Effective Time or, in the event that AMPAM
completes an IPO (as defined in Section 12.15), 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 Common Stock received by the Stockholder pursuant
to this Agreement or any securities convertible into, exchangeable or
exercisable for any shares of AMPAM Common Stock 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 Common Stock 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 Common Stock, whether any such
swap or transaction is to be settled by delivery of shares of AMPAM Common 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 to Section 11 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 8.2,
(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 8.2, (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 8.2.
or (D) pursuant to Article IX hereof, the sale by such Stockholder in an IPO of
shares of AMPAM stock representing not more than 10% of such Stockholder's pro
rata share of the cash portion of the Adjusted or Readjusted (as appropriate)
Merger Consideration; provided, however, that AMPAM shall have the right to
reduce pro rata the





                                     - 36 -
<PAGE>   43


number of shares of each selling Company Stockholder included in such IPO to the
extent that inclusion of such shares would, in the opinion of tax counsel to
AMPAM or its independent auditors, cause the transactions contemplated hereby to
fail as a 368 Reorganization; and provided further, if AMPAM is advised in
writing in good faith by any managing underwriter of an unwritten offering of
the securities being offered pursuant to any registration statement under
Article IX 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 all
AMPAM stockholders and all other security holders in the offering the number of
shares offered for the accounts of such persons (based on the number of shares
held by such person) to a number deemed satisfactory by such managing
underwriter. During this restricted period, the certificates evidencing the
AMPAM Common Stock delivered to the Stockholders pursuant to this Agreement will
bear a legend substantially in the form set forth below:

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED, EXCHANGED,
TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO THE TERMS OF
THE AGREEMENT AND PLAN OF MERGER 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 AGREEMENT AND PLAN OF MERGER EXCEPT
IN ACCORDANCE WITH THE TERMS OF SUCH AGREEMENT. SUCH RESTRICTIONS ON TRANSFER
ARE SET FORTH IN AN AGREEMENT AND PLAN OF MERGER, 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.


                                   ARTICLE IX

                               REGISTRATION RIGHTS

     SECTION 9.1. 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 Company Stockholders prompt written notice of its intent to do so. Upon the
written request of any of the Company Stockholders given within 15 calendar days
after receipt of such notice, notwithstanding the provisions of Section 8
(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 Company
Stockholders pursuant to this Agreement (including any stock issued as or
issuable





                                     - 37 -
<PAGE>   44


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 Company 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 Company 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 Company 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, cause the
transactions contemplated hereby to fail as a 368 Reorganization; provided,
however, that with respect to a proposal by AMPAM to register AMPAM stock under
the 1933 Act in connection with an IPO, no Company Stockholder shall be
permitted pursuant to this Section 9.1 to have included in such registration
more shares of AMPAM stock than permitted to be sold by such Company Stockholder
pursuant to Section 8. 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 9.1 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 Company
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 Company Stockholder disapproves of the terms of the
underwriting, that Company Stockholder may elect to withdraw therefrom by
written notice to AMPAM and the managing underwriter. That Company 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 Company 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, 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
Company Stockholders hereunder. Notwithstanding anything in this Agreement to
the contrary, if AMPAM has entered or enters into any agreement with any Person
providing for rights to register shares of AMPAM stock under the 1933 Act and
such rights are more favorable (as determined by the Company Stockholder's in
their sole discretion) than the rights set forth in Section 9, then AMPAM
acknowledges and agrees that the Company Stockholders shall have the right to
elect to have those more favorable terms apply in lieu of any less favorable
terms contained in Section 9 of this Agreement.

     SECTION 9.2. REGISTRATION PROCEDURE. Whenever AMPAM is required to register
shares of AMPAM stock pursuant to Section 9.1, 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







                                     - 38 -
<PAGE>   45


furnish a representative of the Company Stockholders with copies of all such
documents proposed to be filed) as promptly as practical; (ii) Notify the
Company 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
Company 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 Company
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 Company Stockholder, promptly incorporate in a
prospectus supplement or post-effective amendment such information as the
managing underwriter or underwriters or any participating Company 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 Company Stockholders, any
underwriter participating in any disposition pursuant to such registration
statement, and the counsel retained by the participating Company Stockholders,
counsel for the underwriters and any accountant or other agent retained by
participating Company 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







                                     - 39 -
<PAGE>   46


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 Company 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
Company 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 Company
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 9 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.

     SECTION 9.3. INDEMNIFICATION.

         (a) In connection with any registration under Section 9.1, AMPAM shall
indemnify, to the extent permitted by law, each selling Company 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.




                                     - 40 -
<PAGE>   47


         (b) In connection with any registration under Section 9.1, each selling
Company Stockholder shall furnish to AMPAM in writing such information
concerning the Company 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 Company Stockholder expressly for use in the
registration statement. Notwithstanding the foregoing, the liability of a
Company Stockholder under this Section 9.3 shall be limited to an amount equal
to the net proceeds actually received by such Company 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.

     SECTION 9.4. UNDERWRITING AGREEMENT. In connection with each registration
pursuant to Section 9.1 covering an underwritten registered offering, (i) each
participating Company Stockholder shall execute and deliver to AMPAM a written
power of attorney instrument that (A) appoints an officer of AMPAM as such
Company Stockholder's attorney-in-fact for purposes of executing and delivering
an underwriting agreement among AMPAM, the underwriters named therein and such
Company Stockholder specifying the terms and conditions applicable to the sale
of AMPAM stock of such Company Stockholder in such offering and (B) otherwise is

                                    ARTICLE X

                    NONDISCLOSURE OF CONFIDENTIAL INFORMATION

     SECTION 10.1. GENERAL. The Company 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 or the Surviving
Corporation, such as lists of customers or employees, operational policies, and
pricing and cost policies that are valuable, special, and unique assets of the
Company and will be valuable, special, and unique assets of the Surviving
Corporation. The Company Stockholders agree that they will not disclose such
confidential information to any Person for any purpose or reason whatsoever,
except (a) to authorized representatives of AMPAM, (b) following the Closing,
such information may be disclosed by the Company Stockholders as is required in
the course of performing their duties for AMPAM or the Surviving Corporation and
(c) to their counsel and other advisers, provided that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 10.1; provided,
however that 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 Company 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 Company
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 Company Stockholders of the
provisions of this Section, AMPAM shall be entitled to an injunction restraining
the Company 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, the Company Stockholders shall have none of
the above-mentioned restrictions on their ability to disseminate confidential
information with respect to the Company.

     SECTION 10.2. EQUITABLE RELIEF. Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
the Company, the Surviving Corporation, and/or AMPAM would have no other
adequate remedy, the Company Stockholders agree that the foregoing covenants may
be enforced against them by injunctions, restraining orders, and other equitable
actions and agree to waive any requirement for the securing or posting of any
bond in connection with the obtaining of any such injunctive or any other
equitable relief.

     SECTION 10.3. NON-PUBLIC INFORMATION. The Company Stockholders hereby
acknowledge that if they become aware of "material non-public information" (as
defined under applicable securities laws) regarding AMPAM, that they will be
required, under applicable securities laws, to refrain from trading in AMPAM
securities or disclosing any such information while such information is
non-public. The Company Stockholders further agree to communicate such
requirement to all personnel of the Company, the Surviving Corporation or
others, having Knowledge of such "material non-public information" regarding
AMPAM.

this Agreement are not consummated, each of AMPAM and the Company Stockholders
will return all confidential information regarding the other and the terms and
conditions of the Confidentiality.

                                   ARTICLE XI

                            REDEMPTION OF AMPAM STOCK

     SECTION 11.1. REDEMPTION TRIGGER. In the event that, within three years of
the Effective Time, (i) AMPAM has not consummated an IPO and (ii) any Company
Stockholder has not received cash (including proceeds from the public or private
sale of AMPAM Stock received as consideration hereunder) equal to or exceeding
50% of the Adjusted or Readjusted (as appropriate) Merger Consideration received
by each Company Stockholder, such Company Stockholder shall have the right (the
"Put Right"), but not the obligation, commencing on the third anniversary of the
Effective Time to require AMPAM to purchase a number of shares of AMPAM Common
Stock then owned by such Company Stockholder, subject to Section 11.2 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 Common Stock
after the Effective Time.

     SECTION 11.2. MINIMUM REDEMPTION; LIMITATIONS. If the events specified in
Section 11.1(i) and Section 11.1(ii), with Section 11.1(ii) being determined on
an individual Company Stockholder basis, have not occurred within the time
specified, AMPAM shall be obligated, pursuant to the Put Right, to purchase
annually from each eligible Company Stockholder no less than 10% of the AMPAM
Common Stock held by such Company Stockholder; provided, however, that the
Company Stockholders shall not be entitled to exercise their Put Rights if and
to the extent that (i) the Surviving Corporation has not achieved $6,000,000 of
adjusted earnings before interest, taxes, depreciation and amortization before
corporate allocations for charges and credits ("Adjusted EBITDA") for the year
preceding the year in which a Company Stockholder seeks to exercise his Put
Right, or (ii) the exercise of the Put Rights would, in the written opinion of
tax counsel to AMPAM or its independent auditors cause the transactions
contemplated hereby to fail as a 368 Reorganization. If AMPAM and the Company
Stockholders disagree on the amount of Adjusted EBITDA for the preceding year,
such determination of Adjusted EBITDA will be made by an independent accounting
firm and its determination will be final and binding on all parties. The
redemptions will be funded by internal cash flows or alternative financing
arrangements but AMPAM's obligation to make any redemption pursuant to this
Article XI will be subject to the covenants and restrictions contained in
AMPAM's private or public debt or equity instruments then in existence.

     SECTION 11.3. NOTICE; EXERCISE. The Company Stockholders may exercise their
Put Right by giving written notice (the "Put Notice") to AMPAM within thirty
(30) days after the third anniversary of the Effective Time. If any Company
Stockholder does not provide AMPAM with a Put Notice within such thirty-day
period, the Put Right applicable to such Company Stockholder shall expire. The
date for closing the sale of any shares of AMPAM Common 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






                                     - 45 -
<PAGE>   52


agreed between such holder and AMPAM. At such closing, AMPAM shall make payment
for the AMPAM Common Stock to be repurchased by wire transfer of immediately
available funds to a bank account designated by such Company Stockholder for
such purpose and such Company Stockholder shall deliver to AMPAM certificates,
duly endorsed for transfer, representing the shares of AMPAM Common Stock to be
purchased and sold pursuant to the exercise of such Put Right.

     SECTION 11.4. TERMINATION OF REDEMPTION OBLIGATION. Put Rights with respect
to any individual Company Stockholder will terminate upon receipt by such
Company Stockholder of 50% of the value of his or her Adjusted or Readjusted (as
appropriate) Merger Consideration in cash. Notwithstanding the foregoing, all of
AMPAM's redemption obligations contained in this Article XI 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 Effective Time constitute 50% or more of AMPAM Common Stock
outstanding as of the date of the consummation of such transaction.
