of August 3, 1998 (the "Agreement"), by and among Bruckmann, Rosser, Sherrill &
Co., L.P., a Delaware limited partnership ("BRS"), Penhall Acquisition Corp., an
Arizona corporation ("Newco"), Penhall Rental Corp., a California corporation
formerly known as Penhall International, Inc. (the "Company"), Phoenix Concrete
Cutting, Inc., an Arizona corporation ("PCC"), the stockholders of the Company
identified on the signature pages hereto as the "Management Stockholders" (the
"Management Stockholders") and the stockholders of the Company identified on the
signature pages hereto as the "Non-Management Stockholders" (the 


                                       1


"Non-Management Stockholders" and, together with the Management Stockholders,
the "Sellers").

                                   Background

         A.    The Company has issued and outstanding 421,615 shares of 
Common Stock, without par value ("Existing Company Stock"), all of which are 
owned of record by the Sellers, including 13,750 shares of Existing Company 
Stock issued upon exercise of options to acquire Existing Company Stock and 
3,146 shares of Existing Company Stock issued to certain Management 
Stockholders who are shareholders of Highway Services, Inc. ("HSI") in 
connection with the Company's acquisition of substantially all of the assets 
of HSI.

         B.    Prior to the Closing referred to herein, all of the issued and 
outstanding shares of Existing Company Stock will be exchanged for shares of 
Penhall Class A Common Stock and Penhall Class B Common Stock (each as 
hereafter defined) as provided herein.

         C.    Prior to the Closing, a newly formed subsidiary of PCC will 
have merged with and into the Company, as a result of which (i) the Company 
will become a wholly owned subsidiary of PCC and (ii) each holder of shares 
of Penhall Class A Common Stock and Penhall Class B Common Stock will receive 
an equal amount of shares of Class A Common Stock and Class B Common Stock 
(each as hereafter defined), respectively, of PCC.

         D.    Newco's authorized stock consists solely of 100 shares of 
Common Stock, par value $.01 per share ("Newco Common Stock"). BRS owns one 
(1) share of Newco Common Stock, which presently comprises the sole issued 
and outstanding share of capital stock of Newco.

         E.    The Boards of Directors of the Company and PCC deem it 
advisable and in the best interests of the Company and PCC and their 
stockholders, and the Board of Directors of Newco deems it advisable and in 
the best interests of Newco and its stockholder, to adopt a plan of 
recapitalization of PCC (the "Recapitalization") pursuant to which, among 
other things, (i) Newco will merge with and into PCC (the "Merger") on the 
terms and conditions set forth in this Agreement, with PCC continuing as the 
surviving corporation of such Merger, and (ii) BRS will purchase certain 
securities of PCC as the surviving corporation in the Merger, all on the 
terms and conditions set forth herein.

         F.    It is intended that these transactions be recorded as a 
recapitalization for financial reporting purposes.

         G.    As to certain Management Stockholders and BRS, it is intended 
that certain of these transactions constitute and be treated as transfers of 
property to a corporation controlled by the transferors under Section 351 of 
the Code (as hereafter defined), and comparable provisions of state tax law.

         H.    The parties hereto executed that certain Agreement and Plan of 
Merger, dated as of June 30, 1998 (the "Original Agreement"), and wish to 
amend and restate such agreement as set forth herein.

                                       2


                                      Terms

         NOW, THEREFORE, in consideration of the mutual representations,
warranties, covenants, and agreements, and upon the terms and subject to the
conditions hereinafter set forth, and intending to be legally bound hereby, the
parties do hereby agree as follows:

                                    ARTICLE I

                                   THE MERGER

vested and the Sellers holding such Options shall have exercised all of the
Options for shares of Existing Company Stock;

                (d) all of the outstanding shares of Existing Company Stock
shall have been exchanged for shares of Penhall Class A Common Stock and Penhall

such Penhall Class A Common Stock and Penhall Class B Common Stock in full
redemption and discharge of all of the shares of Existing Company Stock owned by
such Seller (the "Exchange"). Pursuant to the Exchange, each Seller shall
forward certificate(s) evidencing the Existing Company Stock to be exchanged,
together with duly executed stock powers therefor, and, upon filing the Restated
Penhall Charter with the Secretary of State of the State of California, the
Company will forward to such Seller either (x) the certificates representing the

of 


                                       3

                (f) PCC shall have formed a new subsidiary under the laws of the
State of California ("PCC Merger Sub"). PCC Merger Sub shall have been merged
with and into the Company (the "PCC Merger") pursuant to a Plan of Merger
substantially in the form of Exhibit D hereto (the "PCC Plan of Merger"), as a

Common Stock will receive an equal number of shares of Class A Common Stock and
Class B Common Stock, respectively. Pursuant to the PCC Plan of Merger, at the
effective time of the PCC Merger, the Company will exchange all of the shares of
PCC stock held by the Company for 12,386 shares of Class C Common Stock;

                (g) Immediately following the Exchange and the PCC Merger, and
giving effect thereto, PCC shall have issued and outstanding 365,199 shares of

all of which shall be owned beneficially by the Company.

         1.2. Transactions at Closing. The following transactions, which
together shall constitute the Recapitalization, shall be consummated at the
Closing on the Closing Date in the following order and each transaction shall be

purchase, all of the outstanding shares of Class B Common Stock set forth
opposite such Management Stockholder's name and designated as "BRS Purchase
Shares" on Schedule 3.1(a) hereto at a purchase price of $322.94 per share (such
per share consideration multiplied by the total number of shares of Class B
Common Stock being referred to herein as the "Class B Purchase Price");

                (b) Newco shall obtain the proceeds of the Financing (as
hereafter defined);

                (c) upon the terms and subject to the conditions contained in

Corporation Act (the "ABCA"), the separate existence of Newco shall cease, and
PCC shall continue as the surviving corporation (the "Surviving Corporation")
and continue 


                                       4


its corporate existence under the laws of the State of Arizona. Pursuant to the

                (e) BRS, the Management Stockholders and the Surviving
Corporation shall enter into a Securities Holders Agreement (the "Securities
Holders Agreement") substantially in the form attached hereto as Exhibit F; and

                (f) the Surviving Corporation shall sell, and BRS shall
purchase, 299,477.35 shares of Common Stock of the Surviving Corporation at a

         1.3. Terms of the Merger. (a) Effective Time. At the Closing, the
parties hereto shall cause the Merger to be consummated by the execution and
filing of the Plan of Merger (and any other appropriate documents, such as

Arizona containing or referencing a copy of this Agreement and shall make all
other filings or recordings required in accordance with the ABCA. The Plan of
Merger shall provide that the Merger shall become effective immediately upon the
filing of the Plan of Merger. The time when the Merger shall become effective is
hereinafter referred to as the "Effective Time."

                (b) Effect of Merger. At the Effective Time, the effect of the
Merger will be as provided by the ABCA. Without limiting the foregoing, at the
Effective Time, the Surviving Corporation shall thereupon and thereafter possess
all the rights, privileges, immunities, powers and franchises, of a public as
well as of a private nature, of each of Newco and PCC (the "Constituent
Corporations"); and all property, real, personal and mixed, and all debts due on
whatever account, including subscriptions to shares, and all other choses in
action, and all and every other interest, of or belonging to or due to each of
the Constituent Corporations shall be taken and deemed to be transferred to and
vested in the Surviving Corporation without further act or deed; and the title
to any real estate, or any estate or interest therein, vested in either of the
Constituent Corporations shall not revert or be in any way impaired by reason of
the Merger.

                (c) Articles of Incorporation, Bylaws, Directors and Officers of
Surviving Corporation. At the Effective Time, the Articles of Incorporation of
PCC in effect immediately prior to the Effective Time shall be the Articles of
Incorporation of the Surviving Corporation until thereafter amended as provided

                                       5


Corporation and (ii) to change the corporate name of the Surviving Corporation
to "Penhall International Corp." At the Effective Time, the Bylaws of Newco in
effect immediately prior to the Effective Time shall be the Bylaws of the
Surviving Corporation until thereafter amended as provided therein and by law.
The directors of Newco immediately prior to the Effective Time shall be the
directors of the Surviving Corporation, and the officers of PCC immediately
prior to the Effective Time shall be the officers of the Surviving Corporation,
in each case until their successors are duly elected or appointed and qualified
or as otherwise provided in the Bylaws of the Surviving Corporation or by law.

                (d) Conversion of Shares.

                    (i) Conversion of Class A Common Stock. Each share of Class 
A Common Stock issued and outstanding immediately prior to the Effective Time

amount in cash, without interest, equal to the quotient of $117,937,365 (the
"Cash Merger Consideration" and, together with the Class B Purchase Price, the
"Seller Consideration") divided by the total number of shares of Class A Common
Stock issued and outstanding immediately prior to the Effective Time. The
National Christian Charitable Foundation, Inc. (the "NCCF") agrees, however,
that it may receive up to $10,000,000 of Cash Merger Consideration in the form
of an equal amount in aggregate initial liquidation preference amount of the
Senior Exchangeable Preferred Stock;

                    (ii) Conversion of Class B Common Stock. Each share of Class

B Preferred Stock of the Surviving Corporation (the "Class B Merger
Consideration" and, together with the Cash Merger Consideration, the "Merger
Consideration").

                    (iii) Conversion of Class C Common Stock. Each share of

Surviving Corporation.

                    (iv) Cancellation of Treasury Stock. Each share of Class A 
Common Stock or Class B Common Stock then held in the treasury of PCC, shall be
cancelled and retired without any conversion thereof and no payment of any
consideration therefor and thereafter will cease to exist. 

                    (v) Capital Stock of Newco. Each share of Newco Common 
Stock issued and outstanding immediately prior to the Effective Time shall be 
cancelled without any conversion thereof or payment of any consideration 
therefor and thereafter will cease to exist.

         1.4. Closing Date, Time and Place. Unless this Agreement has been 
terminated pursuant to Section 7.1 hereof, the consummation of the Merger (the
"Closing") shall take place on the third business day after all of the
conditions to closing set forth in Article VI are fulfilled or waived, or such
other date and at such other time as the Company and Newco may agree in writing
(the "Closing Date"). The Closing shall take place at 10:00 a.m. local time at
the offices 


                                       6

other location as the parties shall mutually agree.

         1.5. Waiver. Each Seller (on behalf of itself and its affiliates)
hereby waives any and all rights held by it or its affiliates to demand payment
for fair value of any capital stock of the Company or PCC under Chapter 13 of
the California General Corporation Law ("CGCL"), Chapter 13 of the ABCA,
respectively, or similar provisions of applicable law in connection with the
Merger and the other transactions contemplated hereby in respect of any capital
stock of the Company or PCC now or hereafter owned by such Seller or its
affiliates.

         1.6. Payment of Seller Consideration and Merger Consideration;
Surrender of Stock. (a) Upon delivery to BRS of certificates evidencing the
shares of Class B Common Stock representing the BRS Purchase Shares, BRS will
deliver to the holders of the BRS Purchase Shares the Class B Purchase Price to
be received by such holders pursuant to Section 1.2(a) at the Closing by wire
transfer of immediately available funds to one or more accounts designated in
writing by the Seller Representative (as defined below) not less than one (1)
business day prior to Closing.

                (b) Prior to the Effective Time, Newco shall designate one or
more reputable banks or trust companies (the "Exchange Agent") to act at the
Surviving Corporation's sole expense as agent for the holders of Class A Common
Stock and Class B Common Stock immediately prior to the Effective Time (the "A
and B Stockholders") pursuant to the terms of an exchange agent agreement in the
form and substance reasonably satisfactory to Newco and the Seller
Representative (the "Exchange Agent Agreement"), to receive the Cash Merger
Consideration or Class B Merger Consideration to be delivered to such A and B
Stockholders pursuant to Section 1.3(d). Alternatively, Newco may designate the
Surviving Corporation to act as the Exchange Agent in accordance with this
Section 1.6. At or immediately following the Effective Time, Newco shall deposit
or cause to be deposited with the Exchange Agent in trust for the benefit of the
A and B Stockholders, the Merger Consideration to which the A and B Stockholders
shall become entitled pursuant to Section 1.3(d).

                (c) With respect to holders of record of the Class A Common
Stock and Class B Common Stock who shall have given written notice to Newco at
least one (1) Business Day prior to the Effective Time of, in the case of
holders of Class A Common Stock, wire instructions for payment of the Cash
Merger Consideration or, in the case of holders of the Class B Common Stock,
instructions for registration of shares constituting the Class B Merger
Consideration, the Exchange Agent shall deliver to such holders at the Closing,
upon surrender at the Closing to the Exchange Agent of such certificates that
evidenced the shares of Class A Common Stock or Class B Common Stock, the Merger
Consideration payable in respect of the shares of Class A Common Stock or Class
B Common Stock represented by such certificates in accordance with the
instructions for such payment or delivery provided by such holder, and such
certificates shall be cancelled forthwith.

                (d) With respect to holders of record of the Class A Common
Stock and Class B Common Stock who shall not have given proper written notice
and received payment in accordance with subparagraph (c) above, promptly after
the Effective Time, the Exchange Agent 


                                       7


shall mail to each person who was, at the Effective Time, a holder of record of
Class A Common Stock or Class B Common Stock entitled to receive the Merger
Consideration pursuant to Section 1.3(d), a form (mutually agreed to prior to
the Effective Time by Newco and the Company) of letter of transmittal and
instructions for use in effecting the surrender of the certificates that, at the
Effective Time, shall have evidenced any of such shares of Class A Common Stock
or Class B Common Stock to be exchanged pursuant to the Merger. Upon surrender
to the Exchange Agent of such certificates that evidenced the shares of Class A
Common Stock or Class B Common Stock to be exchanged pursuant to the Merger,
together with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, and such other documents as may be
requested, the Exchange Agent shall promptly deliver to the persons entitled
thereto the Merger Consideration payable in respect of such shares of Class A
Common Stock or Class B Common Stock represented by such certificates, and such
certificates shall forthwith be cancelled. Until so surrendered and exchanged,
each such certificate evidencing such shares of Class A Common Stock or Class B
Common Stock shall, after the Effective Time, be deemed to evidence only the
right to receive the Merger Consideration to which such holder is entitled
pursuant to Section 1.3(d).

                (e) If payment of the Merger Consideration in respect of
cancelled shares of Class A Common Stock or Class B Common Stock is to be made
to a person other than the Seller in whose name a surrendered certificate or
instrument is registered, it shall be a condition to such delivery or payment
that (i) the certificate or instrument so surrendered shall be properly endorsed
or shall be otherwise in proper form for transfer, (ii) the Seller requesting
such delivery or payment shall have paid any transfer and other taxes required
by reason of such delivery or payment in a name other than that of the
registered holder of the certificate or instrument surrendered or shall have
established to the reasonable satisfaction of the Surviving Corporation or the
Exchange Agent that such tax either has been paid or is not payable, and (iii)
the Seller requesting such delivery or payment shall have provided security
reasonably satisfactory to BRS and the Seller Representative for such Seller's
indemnification obligations under this Agreement.

                (f) At the Effective Time, the stock transfer books of the
Company shall be closed and there shall be no further registration of transfers
of shares of Class A Common Stock, Class B Common Stock, Class C Common Stock,
Penhall Class A Common Stock, Penhall Class B Common Stock or any Existing
Company Stock thereafter on the records of the Company. From and after the
Effective Time, the holders of certificates evidencing ownership of shares of
Class A Common Stock, Class B Common Stock, Class C Common Stock, Penhall Class
A Common Stock, Penhall Class B Common Stock or any Existing Company Stock
outstanding immediately prior to the Effective Time shall cease to have any
rights with respect to such shares except as otherwise provided herein or by
law. If, after the Effective Time, shares of Class A Common Stock, Class B
Common Stock, Class C Common Stock, Penhall Class A Common Stock, Penhall Class
B Common Stock or Existing Company Stock are duly presented to the Surviving
Corporation for any reason, they will be cancelled and exchanged as provided in
this Article I. No interest shall be paid or accrue on any portion of the Merger
Consideration, except that dividends shall accrue with respect to Series A
Preferred Stock and Series B Preferred Stock in accordance with the terms of
such stock.


                                       8


                (g) Notwithstanding anything to the contrary in this Section
1.6, none of the Surviving Corporation or any party hereto shall be liable to a
holder of shares of Class A Common Stock, Class B Common Stock or any Existing
Company Stock for any amount properly paid to a public official pursuant to any
applicable property, escheat or similar law. If any certificates representing
shares of Class A Common Stock, Class B Common Stock or any Existing Company
Stock shall not have been surrendered prior to two years after the Effective
Time (or immediately prior to such earlier date on which any cash or other
property in respect of such certificate would otherwise escheat to or become the
property of any Authority (as defined in Section 2.14)), any such cash or other
distributions in respect of such certificates shall, to the extent permitted by
applicable law, become the property of the Surviving Corporation, free and clear
of all claims or interest of any person previously entitled thereto.

         1.7. No Further Ownership Rights in Existing Company Stock. The
issuance or payment of the Merger Consideration pursuant to this Article I will
be in full satisfaction of all rights pertaining to the Class A Common Stock,
Class B Common Stock, Penhall Class A Common Stock, Penhall Class B Common Stock
or any Existing Company Stock surrendered in exchange therefor.

         1.8. Termination of Exchange Fund. Any portion of the Merger
Consideration deposited with the Exchange Agent pursuant to Section 1.6 (the
"Exchange Fund") which remains undistributed to the holders of the certificates
representing shares of Class A Common Stock, Class B Common Stock, Penhall Class
A Common Stock, Penhall Class B Common Stock or Existing Company Stock for six
months after the Effective Time shall be delivered to the Surviving Corporation,
upon demand, and any holders of shares of Class A Common Stock, Class B Common
Stock, Penhall Class A Common Stock, Penhall Class B Common Stock or Existing
Company Stock prior to the Merger who have not theretofore complied with this
Article I shall thereafter look only to the Surviving Corporation and only as
general creditors thereof for payment of their claim for cash or other property,
if any.

         1.9. Lost, Stolen or Destroyed Certificates. In the event certificates
representing any shares of Class A Common Stock, Class B Common Stock, Penhall
Class A Common Stock, Penhall Class B Common Stock or Existing Company Stock
have been lost, stolen or destroyed and the holder thereof is unable to obtain a
new certificate by reason of the fact that there can be no further registration
of transfers of such certificates on the records of the Surviving Corporation
pursuant to Section 1.6, the Exchange Agent will issue or pay in exchange
therefor, upon receipt of an affidavit by the holder thereof stating that such
certificates have been lost, stolen or destroyed, the portion of the Merger
Consideration to which the holder is entitled under Section 1.3; provided,
however, that the Surviving Corporation may, in its discretion and as a
condition precedent to the issuance or payment thereof, require the holder to
agree to indemnify, or if such indemnity is deemed inadequate in Surviving
Corporation's reasonable discretion, to deliver a bond in such sum as it may
reasonably direct as indemnity, against any claim that may be made against the
Surviving Corporation, Newco or the Exchange Agent with respect to such
certificates alleged to have been lost, stolen or destroyed.

         1.10. Closing Balance Sheet; Closing Date Indebtedness Amount;
Adjustment to Seller Consideration. (a) As promptly as practicable, but not
later than one hundred twenty (120) 


                                       9


days after the Closing Date, the Surviving Corporation will cause to be prepared
and delivered to the Seller Representative (i) a balance sheet (the "Closing
Date Balance Sheet") of the Company and its Subsidiaries, together with an
unqualified report thereon by KPMG Peat Marwick LLP (the "Company Accountants"),
and (ii) a statement based on such Closing Date Balance Sheet setting forth in
detail a calculation of the Closing Date Indebtedness Amount (as hereafter
defined) and the Adjustment Amount (as hereinafter defined), determined in
accordance with the Applicable Accounting Principles (as hereafter defined) and
this Agreement. For this purpose, (i) "Closing Date Indebtedness Amount" shall
mean an amount equal to all indebtedness (including principal, accrued interest
and any applicable premiums) of the Company or its Subsidiaries to any Seller or
former stockholder of the Company and to Bank of America (consisting in each
case of short- and long-term notes payable), all similar indebtedness of the
Company or its Subsidiaries for borrowed money (excluding borrowings under life
insurance policies payable from the cash surrender value of such policies), and
all amounts drawn under the $2 million dollar letter of credit posted in favor
of Peerless Insurance Company (or any substitute letter of credit) (the
"Peerless L/C"), in each case as of immediately prior to the Closing, whether or
not such indebtedness shall have been repaid or refinanced in connection with
the Closing; (ii) "Adjustment Amount" means the amount, if any, by which (i) the
difference between (x) the Closing Date Indebtedness Amount minus (y) the amount
of the proceeds from the Closing Date Indebtedness Amount used to fund additions
to working capital of the Company and property, plant and equipment of the
Company necessary to support continued growth in the Company's business
(including without limitation all monies used to pay for Proposed Acquisitions
(as defined in Section 1.11(a) below) but excluding all amounts drawn under the
Peerless L/C) or to fund the employee bonuses, employee loans, tax payments and
other items set forth in Schedule 1.10 exceeds (ii) $10,000,000; and (iii)
"Applicable Accounting Principles" means GAAP (as defined in Section 2.6)
applied in a manner consistent with the Audited Financial Statements (as defined
in Section 2.6), except that all amounts, irrespective of size, quantity or
nature shall be considered material.

                (b) After delivery of its calculation of the Closing Date
Indebtedness Amount, the Surviving Corporation shall make available to the
Seller Representative all books, records, work papers, personnel and other
materials and sources used by the Surviving Corporation and the Company's
Accountants to prepare the Surviving Corporation's calculation of the Closing
Date Indebtedness Amount and the Adjustment Amount. The Seller Representative
may dispute any items or amounts reflected on the Closing Date Balance Sheet or
in the Closing Date Indebtedness Amount and the Adjustment Amount calculations
on the basis that such items or amounts were not presented in accordance with
the Applicable Accounting Principles or this Agreement (or on the basis of math,
entry or other errors); provided, however, that the Seller Representative shall
notify the Surviving Corporation in writing of each disputed item or amount
within thirty (30) days of the Seller Representative's receipt of the Closing
Date Balance Sheet and statement of the Closing Date Indebtedness Amount and the
Adjustment Amount (such thirty (30) day period hereinafter referred to as the
"Review Period"). Any such notice of disagreement shall specify those items or
amounts as to which the Seller disagrees (and shall include the Seller
Representative's calculation of the Closing Date Indebtedness Amount and the
Adjustment Amount), and the Sellers and the Seller Representative shall be
deemed to have agreed with all 


                                       10


other items and amounts included in the calculation of the Closing Date
Indebtedness Amount and the Adjustment Amount delivered pursuant to Section
1.10(a).

                (c) If a notice of disagreement shall be duly given pursuant to
Section 1.10(b), the Surviving Corporation and the Seller Representative shall,
during the fifteen (15) business days following receipt of such notice, use
their reasonable best efforts to reach agreement on the disputed items or
amounts in order to determine the Closing Date Indebtedness Amount and the
Adjustment Amount. If, during such period, the Surviving Corporation and the
Seller Representative are unable to reach such agreement, they shall promptly
thereafter cause a nationally recognized firm of independent accountants chosen
and mutually accepted by the parties, or, if no such agreement is reached within
five (5) business days after the end of such period, the firm of Arthur Andersen
LLP (the "Accounting Referee"), to review this Agreement and the disputed items
or amounts for the purpose of calculating the Closing Date Indebtedness Amount
and the Adjustment Amount. In making such calculation, the Accounting Referee
shall consider only those items or amounts in the Surviving Corporation's
calculation of the Closing Date Indebtedness Amount and the Adjustment Amount as
to which the Seller Representative has disagreed. The Accounting Referee shall
deliver to the Surviving Corporation and the Seller Representative, as promptly
as practicable but in no event later than thirty (30) days after retention of
the Accounting Referee by the Surviving Corporation and the Seller
Representative, a report setting forth such calculations. Such report shall be
final and binding upon the Surviving Corporation and the Sellers and shall
constitute an arbitral award upon which a judgment may be entered in any court
having jurisdiction thereof. The cost of such review and report shall be borne
equally by the Surviving Corporation and the Sellers. The "Final Indebtedness
Amount" and the "Final Adjustment Amount" shall mean the Closing Date
Indebtedness Amount and the Adjustment Amount, respectively, (A) as shown in the
Surviving Corporation's calculation delivered pursuant to Section 1.10(a) if no
notice of disagreement with respect thereto is duly delivered pursuant to
Section 1.10(b) or (B) if such a notice of disagreement is delivered, as agreed
by the Surviving Corporation and the Seller Representative pursuant to this
Section 1.10(c) or in the absence of such agreement, as shown in the Accounting
Referee's calculation delivered pursuant to this Section 1.10(c).

                (d) The Sellers and Surviving Corporation agree that they will,
and will cause their (and their affiliates') agents and representatives to,
cooperate and assist in the preparation of the Closing Date Balance Sheet and
the calculation of the Closing Date Indebtedness Amount and the Adjustment
Amount and in the conduct of the audits and reviews referred to in this Section
1.10, including the making available to the extent necessary of books, records,
work papers, and personnel.

                (e) The Surviving Corporation shall be solely responsible for
the fees, costs and expenses due to the Company's Accountants in respect of the
preparation of the Closing Date Balance Sheet and of the calculation of the
Closing Date Indebtedness Amount and the Adjustment Amount pursuant to this
Section 1.10.

                (f) Each of the Sellers shall pay to the Surviving Corporation
such Seller's pro rata share, based on his or its ownership interest in the
Company specified in Schedule 3.1(a) 


                                       11


("Pro Rata Share"), of the Final Adjustment Amount, if any, with interest as
provided in paragraph (g) below.

                (g) Any payments pursuant to paragraph (f) above shall be made
by wire transfer of immediately available funds within ten (10) days after the
Final Indebtedness Amount and the Final Adjustment Amount have been determined
to such account of the Surviving Corporation as may be designated by the
Surviving Corporation in writing (it being understood that if at the conclusion
of the Review Period, any portion of the Adjustment Amount is not in dispute,
such amount shall be paid within ten (10) business days after the conclusion of
the Review Period). The amount of any payment to be made pursuant to this
Section 1.10 shall bear interest from and including the Closing Date to but
excluding the date of payment at a rate per annum equal to the rate of interest
from time to time announced by Morgan Guaranty Trust Company of New York as its
Base Rate in New York City in effect from time to time during the period from
the Closing Date to the date of payment. Such interest shall be payable at the
same time as the payment to which it relates and shall be calculated daily on
the basis of a year of three hundred sixty-five (365) days and the actual number
of days elapsed.

         1.11. Adjustment of Seller Consideration for Certain Company
Acquisitions. (a) With respect to any acquisition (a "Proposed Acquisition") of
any of the acquisition candidates identified on Schedule 1.11 hereto (the
"Acquisition Candidates") consummated by the Company or a Subsidiary of the
Company either prior to Closing or within one hundred twenty (120) days
following the Closing, the Sellers will be entitled to receive the Shareholders'
Valuation Benefit (as defined below) in accordance with the terms and conditions
of this Section 1.11.

                (b) For each Proposed Acquisition consummated prior to Closing
(including the acquisition of HSI), the Merger Consideration and the Class B
Purchase Price shall be increased ratably by an amount equal to 50% of the
Shareholders' Valuation Benefit attributable to such Proposed Acquisition; and
the parties agree that the Merger Consideration reflects such amount
attributable to the acquisition of HSI. In the event that one or more Proposed
Acquisitions are consummated on or before the 120th day following the Closing,
the Sellers shall be entitled to receive, allocated among the Sellers according
to each Seller's respective interest in the total of the Merger Consideration
and the Class B Purchase Price as set forth in Schedule 3.1(a), an amount equal
to 50% of the Shareholders' Valuation Benefit attributable to each such Proposed
Acquisition. Payments pursuant to this paragraph (b) shall be made (i) at the
Closing and in the manner provided in the first sentence of this subparagraph
(b) with respect to any Proposed Acquisition consummated prior to the Closing
(it being acknowledged that the Class B Purchase Price and the Merger
Consideration specified in Sections 1.2(a) and 1.3(d) include such payments with
respect to HSI), and (ii) with respect to any Proposed Acquisition consummated
following the Closing, by wire transfer of immediately available funds within
ten (10) business days after the consummation of such Proposed Acquisition to a
single account for the benefit of the Sellers as may be designated by the Seller
Representative in writing.

                (c) In the event that the EBITDA of an Acquisition Candidate
(acquired pursuant to a Proposed Acquisition for which payment or adjustment
shall have been made under paragraph (b) above) for the period ending on the
first anniversary of the Measurement Date (as defined below) of such Proposed
Acquisition shall equal or exceed 90% of such Acquisition 


                                       12


Candidate's Historical EBITDA (as defined below), the Sellers shall be entitled
to receive from the Surviving Corporation, as an adjustment to the Seller
Consideration, an amount equal to the remaining 50% of the Shareholders'
Valuation Benefit for such Acquisition Candidate. EBITDA shall be calculated in
a manner consistent with the calculation of the Historical EBITDA of such
Acquisition Candidate. Any such payment pursuant to this paragraph (c) shall be
made by the Surviving Corporation by wire transfer of immediately available
funds within ten (10) business days after the first anniversary date of the
consummation of such Proposed Acquisition to a single account for the benefit of
the Sellers as may be designated by the Seller Representative in writing.

                (d) For purposes of this Section 1.11:

                    (i) "Shareholders' Valuation Benefit" means an amount equal 
to 50% of the Valuation Benefit (as defined below);

                    (ii) "Valuation Benefit" means an amount equal to the 
positive difference, if any, of (x) the product of Historical EBITDA (as defined
below) of any Acquisition Candidate multiplied by six (6), less (y) the actual
purchase price (including the value of all assumed bank debt, purchase money
debt and other indebtedness for borrowed money and the estimated value of any
future payments and adjustments as the parties may agree) to be paid for such
Acquisition Candidate;

                    (iii) "Historical EBITDA" of any Acquisition Candidate means
normalized (i.e., after adjustments for non-recurring and similar items)
earnings before interest, taxes, depreciation and amortization ("EBITDA") for
the twelve month period ending on the Measurement Date of such Proposed
Acquisition, it being understood that the Surviving Corporation (or BRS in the
case of any Proposed Acquisition consummated prior to Closing) and the Seller
Representative shall use their respective best efforts to agree upon the
Historical EBITDA of an Acquisition Candidate prior to the date of consummation
of such Proposed Acquisition; provided that the parties agree that Historical
EBITDA of HSI shall equal $3,271,000; and

                    (iv) "Measurement Date" means, with respect to any Proposed 
Acquisition that is consummated, the date that is the last day of the month
immediately preceding the month during which the closing of such Proposed
Acquisition occurs, except that if the closing occurs on the last day of a
month, the Measurement Date shall be the closing date.

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES
                         OF THE SELLERS AND THE COMPANY

         Subject to Section 10.15, each Seller and the Company hereby represent
and warrant jointly and severally to BRS and Newco as follows:

         2.1.   Organization and Standing. (a) The Company is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation, and 


                                       13


has all requisite corporate power and authority to own, lease and operate its
property and to conduct the business in which it is engaged as presently
conducted. The Company is duly qualified to do business as a foreign corporation
and is in good standing in each jurisdiction where the character of the property
owned, leased or operated by it, or the conduct of its business, makes such
qualification necessary, except where the failure to be so duly qualified and in
good standing could not reasonably be expected to have a Material Adverse
Effect. As used herein, the term "Material Adverse Effect" means any change,
effect or circumstance that has or is reasonably likely to have, any material
adverse effect (i) on the assets, liabilities, operations, business, results of
operations or condition (financial or otherwise) of the Company and its
Subsidiaries taken as a whole or (ii) on the ability of the Sellers or the
Company to consummate the transactions contemplated hereby or (iii) on the
ability of each of the Company and its Subsidiaries to continue to operate its
business immediately after the Closing in substantially the same manner as such
business is conducted prior to the Closing.

                (b) Attached hereto as Schedule 2.1(b) are true and complete
copies of the current Articles of Incorporation and Bylaws of the Company, as in
effect on the date of this Agreement.

         2.2. Capitalization. (a) The authorized capital stock of the Company
consists solely of 5,000,000 shares of Existing Company Stock, of which 421,615
shares are issued and outstanding and will be issued and outstanding immediately
prior to the filing of the Restated Penhall Charter. The Sellers are the sole
record owners of the Existing Company Stock. There are no other shares of
capital stock of the Company issued. All of the outstanding shares of the
Company's capital stock (i) are duly authorized, validly issued, fully paid and
nonassessable, (ii) have not been issued in violation of any preemptive rights
of stockholders and (iii) have been offered and sold pursuant to a valid
exemption from registration under the Securities Act of 1933, as amended (the
"Securities Act"), and otherwise in compliance with the Securities Act and the
rules and regulations thereunder.

                (b) The Company has subsidiaries as set forth on Schedule 2.2(b)
(each, a "Subsidiary" and collectively, the "Subsidiaries"). Except for the
Subsidiaries, the Company does not own, and, except as set forth on Schedule
2.2(b), has not owned, directly or indirectly, beneficially or of record, or
have or, except as set forth on Schedule 2.2(b), had any operational control
over, or have any obligation to acquire, any capital stock or other equity
securities of any corporation, nor does the Company have any direct or indirect
equity or ownership investment, or any obligation to incur such investment, in
any person. As used herein, the term "person" means any individual, corporation,
partnership, limited liability company, joint venture, association, trust or
other entity or organization. Each issued and outstanding share of capital stock
or other equity security of the Subsidiaries (i) has been duly authorized and
validly issued, (ii) is fully paid and non-assessable, (iii) has not been issued
in violation of any preemptive rights of equityholders, and (iv) except as set
forth on Schedule 2.2(b) hereto and for the transactions set forth in Article I,
is owned, beneficially and of record by the Company, free and clear of any
claim, lien, security interest, mortgage, deed of trust, pledge, charge,
conditional sale or other title retention agreement, lease, preemptive right,
right of first refusal, option, restriction, tenancy, easement, license,
encroachment (from or onto any other property) or other encumbrance of any kind
(collectively, "Liens"). Except as set forth on Schedule 2.2(b), each Subsidiary
is a corporation 


                                       14


duly organized, validly existing and in good standing under the laws of its
respective state of incorporation set forth on Schedule 2.2(b) hereto and has
full corporate power and authority to carry on its business as it is now being
conducted and to own, operate and lease its properties and assets; is duly
qualified to do business as a foreign corporation and is in good standing in
each jurisdiction where the character of the property owned, leased or operated
by it, or the conduct of its business, makes such qualification necessary,
except where the failure to be so duly qualified and in good standing could not
reasonably be expected to have a Material Adverse Effect. The copies of the
Articles of Incorporation and By-Laws of each Subsidiary heretofore delivered to
Newco are complete and correct copies of such instruments as presently in
effect.

                (c) Except as set forth on Schedule 2.2(c) hereto, there are no
outstanding (i) securities of the Company or any Subsidiary convertible into or
exchangeable for shares of capital stock or equity securities of the Company or
any Subsidiary or (ii) options, warrants, calls or other rights to acquire from
the Company or any Subsidiary, or other obligations or understandings or
arrangements of the Company or any Subsidiary to issue, any capital stock,
equity securities or securities convertible into or exchangeable for capital
stock or equity securities of the Company or any Subsidiary. Except as set forth
on Schedule 2.2(c) hereto and for the transactions set forth in Article I, there
are no outstanding obligations of the Company or any Subsidiary to repurchase,
redeem or otherwise acquire any capital stock or equity securities of the
Company or any Subsidiary (or any of the other securities set forth in the
previous sentence). Except pursuant to this Agreement or as set forth on
Schedule 2.2(c) hereto, neither the Company nor any Subsidiary is a party to, or
bound by, any arrangement, agreement, instrument or order (i) relating to the
transfer of any capital stock or equity securities of the Company or any
Subsidiary, (ii) relating to the dividend or voting rights of any capital stock
or equity securities of the Company or any Subsidiary, or (iii) relating to
rights to registration under the Securities Act of any capital stock or equity
securities of the Company or any Subsidiary.

         2.3. Authorization; Binding Agreement. The Company has full corporate
power and authority to execute and deliver this Agreement and each other
document or instrument contemplated hereby, to perform its obligations hereunder
and thereunder, and to consummate the transactions contemplated hereby and
thereby. The execution and delivery by the Company of this Agreement and each
other document or instrument executed or to be executed by it in connection
herewith, and the consummation by the Company of the transactions contemplated
hereby and thereby, have been, or, with respect to the PCC Merger and the
Merger, will have been prior to Closing, duly and validly authorized by all
necessary corporate and shareholder action. This Agreement has been, and each
other document or instrument to be executed by the Company in connection
herewith will be, duly executed and delivered by the Company, and constitutes,
or will constitute, a legal, valid and binding obligation of the Company,
enforceable against the Company, in accordance with its terms.

         2.4. Conflicts, Consents and Approvals. Except as set forth on Schedule
2.4 hereto, the execution and delivery by the Company of this Agreement and any
other documents or instruments contemplated hereby, the performance by the
Company of its obligations hereunder and thereunder, and the consummation of the
transactions contemplated hereby and thereby, do not and will not:

provision of the Articles of Incorporation or Bylaws of the Company or any
Subsidiary, as such instruments are currently in effect;

                (b) subject to obtaining the consents and approvals specified in
Schedule 2.4, require any consent, approval or notice under, or conflict with,
or result in a violation or breach of, or constitute (with or without the giving
of notice or the lapse of time or both) a default (or give rise to any right of
termination, modification, cancellation or acceleration or result in the
creation or imposition of any Lien upon the property of the Company or a
Subsidiary) under, any of the terms, conditions or provisions of any (i) note,
bond, mortgage, indenture, license, lease, agreement or other document or
instrument or obligation to which the Company or a Subsidiary is a party, under
or pursuant to which any of its properties or assets are held, or by which any
portion of its properties or assets may be bound, or (ii) any permit, license,
approval, franchise or other governmental or regulatory authorization held or
used by or binding on the Company or any of the Subsidiaries, except for
conflicts, violations, breaches, defaults or other events that could not be
reasonably expected to have a Material Adverse Effect;

                (c) violate or contravene any law, statute, rule or regulation,
or any order, writ, judgment, injunction, decree, determination or award
currently in effect, the violation or contravention of which could reasonably be
expected to have a Material Adverse Effect; or

                (d) other than in respect of the HSR Act (as defined in Section
5.5), require any action, consent, approval or authorization of, or review by,
or declaration, registration or filing with, or notice to, any court,
arbitrator, governmental agency or other regulatory authority, or any stock
exchange or similar self-regulatory organization.

         2.5. Litigation. Except as set forth on Schedule 2.5 hereto, (a) there
is no pending or, to the knowledge of the Company, threatened claim, arbitration
proceeding, action, suit, investigation or other proceeding against or involving
the Company or any Subsidiary, or any of the property or rights of the Company
or any Subsidiary, which has had or could reasonably be expected to have a
Material Adverse Effect and (b) neither the Company nor any Subsidiary is in
violation of or default under any order, judgment, writ, injunction or decree of
any court, arbitrator or Authority (as defined in Section 2.14). Any such order,
injunction or decree binding on the Company or any Subsidiary is disclosed in
Schedule 2.5.

         2.6. Financial Statements. Attached hereto as Schedule 2.6(a) are
copies of the audited consolidated financial statements of the Company and its
Subsidiaries for the years ended, and as of, June 30, 1997, June 30, 1996 and
June 30, 1995, together with, in each case, the audit reports thereon of, for
the year ended and as of June 30, 1997, KPMG Peat Marwick LLP or, for the years
ended and as of June 30, 1996 and 1995, Moss Adams LLP (the "Audited Financial

Financial Statements are in accordance with the books and records of the Company
and its Subsidiaries, and fairly present in accordance with generally accepted
accounting principles ("GAAP") consistently applied the consolidated assets,
liabilities and financial position of the Company and its Subsidiaries, as at
the respective dates thereof, and the consolidated results of their operations
for the periods covered thereby. Also attached hereto as Schedule 2.6(a) is a
copy of the unaudited 


                                       16


financial statements of the Company and its Subsidiaries for the nine month
period ended, and as of, March 31, 1998 (the "Interim Financial Statements" and,
together with the Audited Financial Statements, the "Financial Statements").
Except as set forth on Schedule 2.6(b), the Interim Financial Statements are in
accordance with the books and records of the Company and its Subsidiaries, and
fairly present in accordance with GAAP (for interim reporting) consistently
applied the consolidated assets, liabilities and financial position of the
Company and its Subsidiaries, as at the date thereof, and the consolidated
results of their operations for the period covered thereby (except in respect of
normal and recurring year end adjustments, none of which is material in amount).
The contingency, tax and other reserves reflected on the Financial Statements
are adequate, appropriate and reasonable in accordance with GAAP.

         2.7. No Brokers or Finders. Except for William L. Rogers and his
affiliates, the fees related to which shall be borne as provided in Section
10.5, none of the Company, its Subsidiaries, affiliates, officers, directors or
employees, (a) has employed (or will employ) any broker or finder, or (b) has
incurred (or will incur) any liability for any brokerage fees, commissions or
finders' fees in connection with the transactions contemplated by this
Agreement.

         2.8. Taxes. (a) For purposes of this Agreement:

                   (i) "Tax" or "Taxes" means all taxes, charges, fees, levies
or other assessments, including all net income, gross income, gross receipts,
sales, use, ad valorem, value added, transfer, franchise, profits, alternative
minimum, license, withholding, employment, payroll, excise, estimated,
severance, stamp, occupation, real or personal property or other taxes, customs
duties, fees, assessments or charges of any kind whatsoever, together with any
interest and any penalties, additions to tax or additional amounts imposed by
any federal, state, local or foreign tax authority;

                   (ii) "Tax Returns" means all returns, reports, forms or other
information required to be filed with, or supplied to, any tax authority and all
information forms required to be supplied to third parties with respect to any
Taxes; and

                   (iii) For purposes of this Section 2.8 and Section 2.17(m)
hereof relating to Tax matters, "Company" and "Subsidiary" include any
predecessor entity to which the Company or a Subsidiary is a successor for Tax
purposes.

                (b) Except as set forth in Schedule 2.8:

                    All Tax Returns (including consolidated, combined or unitary
federal and state Tax Returns which include or which should include the Company
or any Subsidiary) required to be filed by or on behalf of the Company or any
Subsidiary have been timely filed and each such Tax Return is materially
complete and accurate. All Taxes shown on such Tax Returns have been paid by or
on behalf of the Company and the Subsidiaries when due. The charges, accruals,
and reserves for unpaid Taxes that are reflected on the books of the Company and
each Subsidiary are adequate to cover such Taxes in accordance with GAAP.
Neither the Company nor any Subsidiary has filed a consent, election or
agreement under Section 341(f) of the Internal Revenue Code of 1986, as amended,
and the rules and regulations promulgated thereunder 


                                       17




(collectively, the "Code"). No Liens for Taxes have been filed with respect to
any property of the Company or any Subsidiary except for Taxes not yet due,
there is no unpaid assessment of Taxes against the Company or any Subsidiary, no
claims are being asserted with respect to any Taxes of the Company or any
Subsidiary and to the Company's knowledge no examination is being conducted or
is pending which could result in Taxes being owed by the Company or any
Subsidiary. Neither the Company nor any Subsidiary has been advised by any tax
authority that it has or may have an obligation to file Tax Returns in a
jurisdiction where the Company or Subsidiary has not filed or has ceased filing
Tax Returns. The Company and each Subsidiary have complied in all material
respects with applicable laws, rules and regulations relating to the payment and
withholding of Taxes and have withheld and properly remitted all Taxes required
to be withheld from the wages, salaries, payments or transfers of property to
employees and independent contractors. There are no effective waivers or
consents extending the statute of limitations with respect to Taxes for which
the Company or any Subsidiary could be liable. Neither the Company nor any
Subsidiary is a party to any agreement under which the Company or any Subsidiary
could be liable to indemnify another person for Taxes. Neither the Company nor
any Subsidiary is subject to any adjustment under Section 481 of the Code.
Neither the Company nor any Subsidiary is the subject of any private letter
ruling from, or closing agreement with any tax authority. Neither the Company
nor any Subsidiary owns an equity interest in any entity treated as a
partnership for federal income tax purposes. Neither the Company nor any
Subsidiary has ever been a member of an affiliated group that files or filed
consolidated federal income tax returns other than the affiliated group of which
the Company is the common parent.

                (c) Neither the Company nor any Subsidiary has made, or is
obligated to make, any "excess parachute payment" within the meaning of Section
280G of the Code.

         2.9. Absence of Undisclosed or Contingent Liabilities. Except as set
forth on Schedule 2.9 hereto and except as (and to the extent) accrued for in
the interim balance sheet, as of the date (the "Interim Balance Sheet Date") of
the balance sheet included in the Interim Financial Statements (the "Interim
Balance Sheet"), neither the Company nor any Subsidiary had any liability or
obligation, other than (i) executory obligations under contracts and other
contractual or employment arrangements not requiring disclosure in the Interim
Balance Sheet under GAAP and incurred in the ordinary course of business
consistent with past practice and (ii) liabilities and obligations arising from
normal year-end adjustments none of which, individually or in the aggregate,
would be material to the Company's financial position as reflected in the
Interim Financial Statements. Since the Interim Balance Sheet Date, neither the
Company nor any Subsidiary has become subject to any such liability or
obligation, other than (a) liabilities and obligations incurred in the ordinary
course of business consistent with past practice of a type reflected on the
Interim Balance Sheet which are not in an amount materially in excess of the
liabilities and obligations accrued for in the Interim Balance Sheet Date, (b)
executory obligations under contracts and other contractual or employment
arrangements not requiring disclosure in the Interim Balance Sheet under GAAP
and incurred in the ordinary course of business consistent with past practice
(c) liabilities and obligations arising from normal year-end adjustments none of
which, individually or in the aggregate, would be material to the Company's
financial position as reflected in the Interim Financial Statements and (d)
liabilities and obligations set forth on Schedule 2.9 hereto. Notwithstanding
the foregoing, no representations or warranties are given in this Section 2.9
with respect to liabilities or obligations arising from environmental matters or


                                       18


conditions, employee benefit plans or pursuant to ERISA, and Sections 2.12 and
2.20 shall contain the only representations and warranties with respect to such
items.

         2.10. Property. (a) Except as set forth on Schedule 2.10(a) hereto, the
Company, or if so designated in Schedule 2.10(a), a Subsidiary, has (and will
continue to have immediately after the Closing) good and valid title to all
assets and properties the Company and the Subsidiaries purport to own (other
than the Real Property, as hereinafter defined), tangible and intangible, in
each case free and clear of any Liens, except for inventories and other assets
disposed of by the Company or any Subsidiary prior to the Closing in the
ordinary course of business consistent with past practice and except for Liens
for taxes not yet due and payable (collectively, the "Personal Property").

                (b) Except as set forth in Schedule 2.10(a) hereto, all of the
assets, tangible and intangible, used in the operation of the business of the
Company and the Subsidiaries as of the Interim Balance Sheet Date were owned,
leased or licensed by the Company and the Subsidiaries or, with respect to
intellectual property, in the public domain.

                (c) Attached hereto as Schedule 2.10(c) is a list of (i) all of
the owned real property of the Company and the Subsidiaries (collectively, the
"Owned Real Property"), (ii) all leases, assignments of leases, subleases,
licenses, rights of use or occupancy and other written agreements pursuant to
which the Company or the Subsidiaries lease, sublease, use or occupy real
property (other than Job Sites (as defined below) used or occupied)
(collectively, the "Tenant Leases"), and (iii) all leases, assignments of
leases, subleases, rights of occupancy and other written agreements pursuant to
which the Company or any of the Subsidiaries lease, have assigned leasehold
estates, subleased or otherwise let to any person any Real Property (as
hereinafter defined) or any portion of or interest therein (the "Landlord
Leases"). The interests of the Company and the Subsidiaries in the Real Property
constitute the only interests in real property required to be owned by the
Company or the Subsidiaries in order that the Company and the Subsidiaries may
conduct their business as presently conducted, except for job sites owned or
leased by customers of either the Company or any of its Subsidiaries ("Job
Sites").

         As used in this Agreement, the following terms have the following
meanings:

                   (i) "Exceptions That Will Not Exist At Closing" means those

                (b) The Company or a Subsidiary solely and exclusively owns all
right, title and interest in and to the Intellectual Property, except as set

record for all applications for trademark, service mark, and copyright

or requirements relating to Hazardous Substances. During the past three 
years, neither the Company nor any Subsidiary has received any notification 
of any asserted present or past failure by the Company or any Subsidiary to 
comply with any laws, rules or regulations, except where an asserted present 
or past failure to comply could not reasonably be expected to

                                       24


have a Material Adverse Effect and except for laws, regulations or 
requirements relating to Hazardous Substances.

or Subsidiary, as applicable, and, to the Company's knowledge, the other parties
thereto in accordance with its terms. Except as set forth on Schedule 2.19 and

Material Adverse Effect, neither the Company nor any Subsidiary is in default
under or has breached any of the Contracts and no act or omission has occurred
which, with notice or lapse of time or both, would constitute a breach or
default under any term or provision of any such Contract. To the knowledge of
the Company, no other party is in breach or default under any of such Contracts,
and no act or omission has occurred by any other party thereto which, with
notice or lapse of time or both, would constitute such a breach or default under
any term or provision thereof. Subject to receipt of the consents set forth in
Schedule 2.4, the Contracts will remain in full force and effect (without any
breach or default or modification thereunder, or event which could give rise to
breach, default or modification) for the benefit of the Company, the
Subsidiaries and the Surviving Corporation following the Closing.

         2.20. Benefit Plans. (a) Set forth on Schedule 2.20(a) is a true and
complete list of each (i) "employee benefit plan," as defined in Section 3(3) of

independent contractor of the Company or a Subsidiary or under which the Company
or any ERISA Affiliate has any liability with respect to any employee, former
employee, director, officer or independent contractor of the Company or
Subsidiary (the "Benefit Plans").

                (b) As applicable with respect to each Benefit Plan (other than
a Multiemployer Plan), the Company has made available to Newco true and complete
copies of (i) each Benefit Plan, including all amendments thereto, and in the
case of an unwritten Benefit Plan, a written description thereof, (ii) all trust
documents, investment management contracts, custodial agreements and insurance
contracts relating thereto, (iii) the current summary plan description and each
summary of material modifications thereto, (iv) the three most recent annual
reports (Form 5500 and all schedules thereto) filed with the Internal Revenue
Service ("IRS"), (v) the most recent IRS determination letter and each currently
pending application to the IRS for a determination letter, (vi) the three most
recent summary annual reports, actuarial reports, financial statements and
trustee reports and (vii) all records, notices and filings concerning IRS or
Department of Labor audits or investigations, "prohibited transactions" within
the meaning of Section 406 of ERISA or Section 4975 of the Code and "reportable
events" within the meaning of Section 4043 of ERISA. The Company has made a
written request to the sponsoring union of each Multiemployer Plan for true and
complete copies of the three most recent annual reports (Form 5500 and all
schedules thereto) filed with the IRS, and statements or computations regarding
potential withdrawal liability, if any. The Company made available to Newco true
and complete copies of such information and documentation outlined in the
previous sentence with respect to such Multiemployer Plans that the Company has
in its possession on or prior to the date hereof and the Closing Date, as
applicable.

                (c) Except as otherwise disclosed with particularity on Schedule
2.20(c):

                    (i) There has been no failure by the Company or any ERISA
Affiliate to comply with the provisions of ERISA and the Code applicable to the
Benefit Plans (other than a Multiemployer Plan), which failure could reasonably
be expected to have a Material Adverse Effect. There has been no failure by any
Benefit Plan (other than a Multiemployer Plan) to be maintained, operated and
administered in compliance with its terms and any related documents or
agreements and the applicable provisions of ERISA and the Code, which failure
could reasonably be expected to have a Material Adverse Effect.

                    (ii) There has been no failure by any Benefit Plans (other
than a Multiemployer Plan) which are "employee pension benefit plans" within the
meaning of Section 3(2) of ERISA and which are intended to meet the
qualification requirements of Section 401(a) of 


                                       29


the Code (each a "Pension Plan") to meet the requirements for such qualification
or by their related trusts to meet the requirements for exemption from taxation
under Section 501(a) of the Code, which failure could reasonably be expected to
have a Material Adverse Effect.

                    (iii) All Pension Plans (other than a Multiemployer Plan)
have received determination letters from the IRS to the effect that such Pension
Plans are qualified and their related trusts are exempt from federal income
taxes and no determination letter with respect to any Pension Plan has been
revoked nor, to the knowledge of the Company is there any reason for such
revocation, nor has any Pension Plan been amended since the date of its most
recent determination letter in any respect which would adversely affect its
qualification.

                    (iv) No Benefit Plan (other than a Multiemployer Plan) is
now or at any time has been subject to Part 3, Subtitle B of Title I of ERISA or
Title IV of ERISA. All contributions to, and payments from, any Benefit Plan
which may have been required in accordance with the terms of such Benefit Plan
or any related document have been timely made. All such contributions to, and
payments from, any Benefit Plan, except those to be made from a trust, qualified
under Section 401(a) of the Code, for any period ending before the Closing Date
that are not yet, but will be, required, are properly accrued and reflected on
the Interim Balance Sheet.

                    (v) Neither the Company nor any ERISA Affiliate has ever
contributed to, or been required to contribute to any Multiemployer Plan .
Neither the Company nor any ERISA Affiliate has any liability (contingent or
otherwise) relating to the withdrawal or partial withdrawal from a Multiemployer
Plan. All required contributions, withdrawal liability payments or other
payments of any type that the Company or any ERISA Affiliate have been obligated
to make to any Multiemployer Plan have been duly and timely made. Any withdrawal
liability incurred with respect to any Multiemployer Plan has been fully paid as
of the date hereof. Neither the Company nor any ERISA affiliate has undertaken
any course of action that could reasonably be expected to lead to a complete or
partial withdrawal from any Multiemployer Plan. To the knowledge of the Company,
no Multiemployer Plan is in "reorganization" within the meaning of Section 4241
of ERISA nor has notice been received by the Company or any ERISA Affiliate that
any such Multiemployer Plan will be placed in "reorganization."

                    (vi) To the knowledge of the Company, there are no pending
audits or investigations by any governmental agency involving the Benefit Plans,
and no threatened or pending claims (except for individual claims for benefits
payable in the normal operation of the Benefit Plans), suits or proceedings
involving any Benefit Plan, any fiduciary thereof or service provider thereto,
nor to the knowledge of the Company is there any basis for any such claim, suit
or proceeding.

                    (vii) Neither the Company, any ERISA Affiliate, nor to the
knowledge of the Company, any fiduciary, trustee or administrator of any Benefit
Plan, has engaged in or, in connection with the transactions contemplated by
this Agreement, will engage in any transaction with respect to any Benefit Plan
which would subject any such Benefit Plan, the Company, any ERISA Affiliate,
Newco or the Surviving Corporation to a tax, penalty or liability for a
"prohibited transaction" under Section 406 of ERISA or Section 4975 of the Code.
None of the 


                                       30


assets of any Benefit Plan (other than a Multiemployer Plan) is invested in any
property constituting "employer real property" or an "employer security," within
the meaning of Section 407 of ERISA.

                    (viii) All insurance premiums with respect to any insurance
policy related to a Benefit Plan (other than a Multiemployer Plan) for any
period up to and including the Closing Date shall have been paid, or accrued and
booked on or before the Closing Date, and, with respect to any such insurance
policy or premium payment obligation, neither the Company nor any ERISA
Affiliate shall be subject to a retroactive rate adjustment, loss sharing
arrangement or other actual or contingent liability.

                    (ix) There has been no failure by any Benefit Plan that is a
"group health plan" within the meaning of Section 607 of ERISA and that is
subject to Section 4980B of the Code to comply with the continuation coverage
requirements of the Code and ERISA, which failure could reasonably be expected
to have a Material Adverse Effect.

                    (x) No Benefit Plan provides benefits, including, without
limitation, death or medical benefits, beyond termination of service or
retirement other than (A) coverage mandated by law, (B) death or retirement
benefits under a Benefit Plan qualified under Section 401(a) of the Code or (C)
coverage mandated by the terms of any collective bargaining agreement; provided,
however, that neither the Company nor any ERISA Affiliate will be required,
whether pursuant to the terms of any collective bargaining agreement or
otherwise, to make any contributions or payments to the applicable health or
welfare plan or fund with respect to any period after the termination of the
collective bargaining relationship between the applicable union and the Company
or any ERISA Affiliate. Neither the Company nor any ERISA Affiliate has made a
written or oral representation to any current or former employee promising or
guaranteeing any employer paid continuation of medical, dental, life or
disability coverage for any period of time beyond retirement or termination of
employment.

                    (xi) The Sellers' and the Company's execution of, and
performance of the transactions contemplated by, this Agreement will not
constitute an event under any Benefit Plan that will result in any payment
(whether as severance pay or otherwise), acceleration, vesting or increase in
benefits with respect to any employee.

                    (xii) All of the employees whose primary responsibility
relate to the business of the Company and the Subsidiaries are employed by the
Company and the Subsidiaries and no such individual is employed by any other
ERISA Affiliate.

                (d) As used herein, the capitalized terms below have the
following meanings:

         5.9. Competition. (a) Following the Closing, each Seller set forth on
Schedule 5.9 hereto, on behalf of itself and its affiliates, agrees that, for
the period specified opposite such Seller's name on Schedule 5.9 hereto, neither
it nor its affiliates shall, without the prior written consent of the Surviving
Corporation, directly or indirectly, as owner, partner, agent, employee,
consultant or otherwise, (i) engage in any business in the Territory (as defined
below) which provides services or sells or leases products similar or equivalent
to the products or services provided or sold immediately after the Closing by
the Company and the Subsidiaries (a "Competitive Business") or (ii) solicit,
attempt to solicit for employment or otherwise engage the services of, or become
associated in any Competitive Business with, any person who was an employee,
officer or director of the Company or the Subsidiaries at any time during the
twelve (12) months preceding the date of this Agreement. Without limiting the
generality of the foregoing, following the Closing, Roger C. Stull, on behalf of
himself and his affiliates, agrees that, for the period specified opposite Mr.
Stull's name on Schedule 5.9 hereto, neither he nor his affiliates shall,
without the prior written consent of the Surviving Corporation, directly or
indirectly, as owner, partner, agent, employee, consultant or otherwise, assist
or promote in any manner Gregory J. Stull, Kimberlie R. McTavish, Christine
Marie Kiser or Nicole Lynn Stull (the "Stull Children") in engaging in any
activity prohibited by the foregoing sentence, it being understood and agreed
that if any of the Stull Children engages in any activity described in this
Section 5.9(a) during the period specified opposite Roger C. Stull's name on
Schedule 5.9 hereto, then there shall be a rebuttable presumption that Roger C.
Stull assisted or promoted such activity. For purposes of this Agreement,
"Territory" shall mean each and every county located in the states of
California, Arizona, Nevada, Minnesota, Alabama, Arkansas, Colorado, Delaware,
Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky,
Louisiana, Maryland, Michigan, Mississippi, Missouri, Montana, Nebraska, New
Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma,
Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia,
Washington, West Virginia, Wisconsin, Wyoming, and all other counties of other
states of the United States or foreign jurisdictions in which the Company has
conducted business, or during the period applicable to any Seller, shall have
conducted business. None of the foregoing shall (i) prevent any Seller from
owning up to 5% of the outstanding equity of a publicly-traded company or from
making indirect investments through an investment 


                                       40


partnership or other investment entity in any corporation, partnership, limited
liability company or other person or entity, (ii) prevent Roger C. Stull from
participating in charitable, business or trade associations, or in the auto
racing industry in any respect, or (iii) be construed as being binding in any
way on the Stull Children or on William L. Rogers or his affiliates (other than
an affiliate who is a Seller listed in Schedule 5.9).

                (b) The parties agree that to the extent any provision or
portion of Section 5.9(a) shall be held, found or deemed to be unreasonable,
unlawful or unenforceable by a court of competent jurisdiction, then any such
provision or portion thereof shall be deemed to be modified to the extent
necessary in order than any such provision or portion thereof shall be legally
enforceable to the fullest extent permitted by applicable law; and the parties
do further agree that any court of competent jurisdiction shall, and the parties
hereto do hereby expressly authorize, require and empower any court of competent
jurisdiction to, enforce any such provision or portion thereof in order that any
such provision or portion thereof shall be enforced to the fullest extent
permitted by applicable law.

                (c) As the violation by a Seller or its affiliates of the
provisions of this Section 5.9 would cause irreparable injury to the Surviving
Corporation, and there is no adequate remedy at law for such violation, the
Surviving Corporation shall, notwithstanding anything to the contrary herein,
have the right in addition to any other remedies available, at law or in equity,
to seek to enjoin such Seller or its affiliates in a court of equity from
violating such provisions. Each Seller, on behalf of itself and its affiliates,
hereby waives any and all defenses it may have on the ground of lack of
jurisdiction or competence of the court to grant an injunction or other
equitable relief, or otherwise. The existence of this right shall not preclude
any other rights and remedies at law or in equity which the Surviving
Corporation may have. The prevailing party in any enforcement action or court
proceeding under this Section 5.9 shall be entitled to the extent permitted by
law to reimbursement from the other party for all of the prevailing party's
costs, expenses and attorneys' fees.

obligation or pay any money to any third party or commence any legal,
administrative or other proceeding).

(collectively, the "Title Company"), irrevocably committing the Title Company

contained in the Title Commitment and reasonably acceptable to Newco) to

parcel of Real Property in amounts substantially the same as those of the

providing financing in connection with the transactions contemplated hereby and
otherwise in form and substance acceptable to Newco, or (ii) with respect to
parcels of Owned Real Property not covered by the preceding clause (i), ALTA or,
with respect to all Owned Real Property located in California, CLTA form of

each parcel of the Owned Real Property in the Company in the respective amounts
listed on Schedule 2.11(a), where applicable, or in amounts substantially the
same as those of the existing policies or in such higher amounts as may be
required by any lender providing financing in connection with the transactions
contemplated hereby, in any case subject to no Liens or exceptions to title

5.19, for the Exceptions That Will Not Exist At Closing, (y) minor imperfections

include such endorsements thereto as may reasonably be requested by Newco,
provided that Newco shall bear the cost of any such endorsements. On or prior to
the Closing Date, the Company and the Subsidiaries shall execute and deliver, or
cause to be executed and delivered, to the Title Company any affidavits

authorities having jurisdiction over such matters with respect to such parcel of
Real Property for which BRS or Newco requests such letters (collectively, the

         6.3. Conditions Precedent to the Sellers' Obligations. The Sellers' and
the Company's obligation to consummate the transactions contemplated hereby
shall be subject to the fulfillment of each of the following additional
conditions, any one or more of which may be waived in writing by the Seller
Representative and the Company:

                (a) Each of BRS and Newco shall have performed in all material
respects its obligations under this Agreement required to be performed on or
prior to the Closing Date pursuant to the terms hereof;

                (b) the representations and warranties of each of BRS and Newco
contained in this Agreement that are not qualified by materiality shall be true
and correct in all material respects, and the representations and warranties of
BRS and Newco set forth in this Agreement that are qualified by materiality
shall be true and correct, on and as of the Closing Date (irrespective of any
notice delivered to the Sellers or the Company after the date hereof) with the


                                       46


same force and effect as though such representations and warranties had been
made on and as of the Closing Date;

                (c) the Sellers and the Company shall have received a
certificate of an officer of BRS and Newco, dated the Closing Date, on behalf of
Newco, certifying to the fulfillment of the conditions set forth in clauses (a)
and (b) above;

                (d) the Sellers and the Company shall have received a
certificate, dated the Closing Date, duly executed by an officer of Newco
certifying as to: (i) the attached copy of the resolutions of Newco authorizing
and approving the execution, delivery and performance of, and the consummation
of the transactions contemplated by, this Agreement and any other documents or
instruments contemplated hereby, and stating that the resolutions thereby
certified have not been amended, modified, revoked or rescinded; and (ii) the
incumbency, authority and specimen signature of each officer of Newco executing
this Agreement or any other document or instrument contemplated hereby;

                (e) the Sellers and the Company shall have received a
certificate, dated the Closing Date, duly executed by an authorized person of
BRS certifying as to: (i) the attached copy of the resolutions of BRS
authorizing and approving the execution, delivery and performance of, and the
consummation of the transactions contemplated by, this Agreement and any other
documents or instruments contemplated hereby, and stating that the resolutions
thereby certified have not been amended, modified, revoked or rescinded; and
(ii) the incumbency, authority and specimen signature of each authorized person
of BRS executing this Agreement or any other document or instrument contemplated
hereby;

                (f) the Sellers and the Company shall have received from counsel
for Newco an opinion dated the Closing Date in the form of Exhibit L;

                (g) BRS and the Surviving Corporation shall have validly
executed and delivered the Securities Holders Agreement referred to in Section
5.8;

                (h) On or prior to June 30, 1998, the Company shall have validly
executed and delivered the Compensation Agreement;

                (i) The Surviving Corporation shall have validly executed and
delivered the Employment Agreements;

                (j) The Surviving Corporation shall have adopted the Stock
Option Plan;

                (k) the Company and the Subsidiaries shall have executed and
delivered to the Sellers a Mutual Release and Satisfaction in the form of
Exhibit M hereto; and

                (l) BRS and Newco shall have furnished to the Sellers and the
Company evidence reasonably satisfactory to the Seller Representative and the
Company that the purchasers of the senior subordinated notes in the Financing
and Newco's and the Surviving Corporation's other lenders (including all bank
lenders) have consented to the payment of the Cash Merger Consideration, it
being understood that incorporation of the language provided by Sellers prior to


                                       47


the date hereof for inclusion in the indenture for the senior subordinated notes
and the loan agreements with bank lenders to Newco and the Surviving Corporation
shall constitute conclusively such satisfactory evidence.

         6.4. Up-Dating of Disclosure Schedules. Prior to the Closing, the
Company and the Sellers may deliver to Newco and BRS revised disclosure
Schedules modifying or qualifying the representations and warranties of the
Sellers and the Company under Articles II and III hereof with respect to any
matter or event that causes an inaccuracy or breach of a representation or
warranty and that first arises prior to the Closing Date (whether before or
after the date of this Agreement), except for matters or events of which any
Seller (solely with respect to such Seller's representations and warranties in
Article III) or the Company (solely with respect to the Company's and the
Sellers' representations and warranties in Article II) had knowledge as of the
date of this Agreement; provided, that the Company also may add matters or
events to the revised disclosure Schedules of which Floyd E. Skor, but no other
person listed in Section 10.12(c), had knowledge as of the date of this
Agreement. Such revised disclosure Schedules shall be deemed to have modified
the representations and warranties made by the Sellers and the Company as of the
date of the Original Agreement and to be made as of the time immediately prior
to the consummation of the Exchange and to have superseded any similarly
numbered Schedule delivered to Newco and BRS on the date hereof. The foregoing,
however, shall not affect the condition to the Closing obligations of BRS and
Newco contained in Section 6.2(b) as such condition relates to such
representations and warranties prior to giving effect to the delivery of such
revised Schedules. In the event that the condition to the Closing obligations of
BRS and Newco set forth in Section 6.2(b), as such condition relates to
representations and warranties, shall not have been satisfied, but would be
satisfied after giving effect to the delivery of revised disclosure Schedules
under this Section 6.4, then, subject to Section 8.5(j), the sole remedy of
Newco and BRS in respect of the failure of such condition shall be to elect not
to consummate the transactions contemplated by this Agreement.

                                   ARTICLE VII

                           TERMINATION AND ABANDONMENT

         7.1. Termination. Except with respect to provisions that expressly
survive the termination of this Agreement, this Agreement may be terminated:

                (a) by mutual written agreement of BRS, Newco, the Company and
the Sellers;

                (b) by BRS or Newco (provided BRS or Newco is not in material
breach of this Agreement), by written notice to the parties hereto, at any time
if (i) the representations and warranties of a Seller or the Company in this
Agreement were incorrect in any material respect when made or at any time
thereafter, or (ii) any of the Sellers or the Company is in breach in any
material respect of any of its covenants or agreements in this Agreement (each,
a "Seller Breach"), and, in either of such cases, such Seller Breach continues
uncured for ten (10) days after written notice thereof by BRS or Newco;
provided, however, if such Seller or the Company (as the case may be) commences
to effect a cure within the foregoing ten-day period, such person shall be
permitted such additional time as may be reasonable (based on the nature of the
Seller 


                                       48


Breach, the possibility for cure, and the effect of delay on the party seeking
termination) to cure so long as such person diligently continues to seek to
effect a cure;

                (c) by the Sellers (provided no Seller is in material breach of
this Agreement), by written notice to the parties hereto, at any time if (i) the
representations and warranties of BRS or Newco in this Agreement were incorrect
in any material respect when made or at any time thereafter, or (ii) BRS or
Newco is in breach in any material respect of any of its covenants or agreements
in this Agreement (each, a "Newco Breach"), and, in either of such cases, such
Newco Breach continues uncured for ten (10) days after written notice thereof by
the Sellers; provided, however, if BRS or Newco (as the case may be) commences
to effect a cure within the foregoing ten-day period, such entity shall be
permitted such additional time as may be reasonable (based on the nature of the
Newco Breach, the possibility for cure, and the effect of delay on the party
seeking termination) to cure so long as such entity diligently continues to seek
to effect a cure;

                (d) by BRS, Newco or the Sellers, if a court of competent
jurisdiction or governmental or regulatory body shall have issued an order,
decree or ruling, or taken any other action, restraining, enjoining or otherwise
prohibiting the Closing of the transactions contemplated hereby and such order,
decree, ruling or other action shall have become final and non-appealable; or

                (e) by BRS, Newco, the Company or the Sellers, if the Closing
shall not have occurred by August 31, 1998; provided, however, that at the time
of any such termination, the terminating party is not in willful and material
breach of any of its representations, warranties, covenants or obligations
hereunder.

         7.2. Effect of Termination. If this Agreement is terminated as provided
herein, no party shall have any liability or further obligation to any other
party under the terms of this Agreement or otherwise; provided that if such
termination shall result from the willful breach by the non-terminating party of
any representation or warranty, or the failure of the non-terminating party to
perform a covenant of this Agreement, such party shall be fully liable for any
and all damages incurred or suffered by the other parties as a result of such
failure. The provisions of Section 10.5 shall survive any termination of this
Agreement pursuant to Section 7.1.

                                  ARTICLE VIII

                                 INDEMNIFICATION

         8.1. The Sellers' Obligations to Indemnify. Subject to the limitations
and procedures contained in this Article VIII, from and after the Closing, the
Sellers, jointly and severally, shall indemnify, defend and hold harmless Newco,
BRS, the Surviving Corporation and each of their affiliates, and their
respective directors, officers, employees and representatives (each, a "Company
Indemnified Party"; provided that such term shall not include any Seller
regardless of their affiliation with the Surviving Corporation), from and
against any and all claims, losses, settlements, fines, liabilities, damages,
deficiencies, costs or expenses (including interest, penalties and reasonable
attorneys' fees and disbursements) (collectively, "Losses") suffered, sustained,


                                       49


incurred or required to be paid by any such Company Indemnified Party due to,
based upon, arising out of or otherwise in respect of (i) any inaccuracy in, or
any breach of, any representation or warranty of the Sellers or of the Company
contained in this Agreement (or any schedule hereto or any certificate or other
agreement delivered on behalf of Sellers hereunder), determined without regard
to any materiality, Material Adverse Effect, Material Adverse Change,
substantial compliance or similar exception or qualification contained in or
otherwise applicable to such representation or warranty; provided that, the
indemnification obligation of the Sellers with respect to the representations
and warranties contained in Article III hereof shall be several and not joint as
to each Seller, (ii) any breach of any covenant or agreement of the Sellers or
the Company contained in this Agreement, (iii) any Loss, whether disclosed or
undisclosed and whether existing prior to, on or after the Closing (other than
on account of defaults, violations or breaches arising from actions first
occurring after the Closing by the Surviving Corporation or any of its
subsidiaries under any obligations assumed by it or them in connection with the
transactions contemplated hereby), arising from or relating to any sold or
discontinued business or operation of the Company or any Subsidiary (or any
respective predecessor) or any business or activity conducted by the Company or
any Subsidiary (or any respective predecessor) other than the businesses and
activities conducted by the Company and its Subsidiaries on or after the date of
the Original Agreement, (iv) the enforcement by any Company Indemnified Party of
its rights under this Agreement, (v) any Loss, whether disclosed or undisclosed,
arising from or relating to (A) environmental conditions first occurring,
existing or arising prior to the Closing due to, based upon, arising out of or
otherwise in respect of a Release or threat of Release of Hazardous Substances
at any property owned or leased by the Company or the Subsidiaries prior to the
date of the Original Agreement (but not on the date thereof) (whether into the
air, soil, ground or surface waters on or off-site), (B) the off-site
transportation, storage, treatment, recycling, disposal or spill of Hazardous
Substances (but excluding crushed concrete, concrete slurry, asphalt, rebar and
associated materials that are generated in the ordinary course of operations of
the Company or the Subsidiaries) generated or caused by the Company or the
Subsidiaries, prior to the Closing, or (C) any investigation, remediation or
other response costs ("Remediation Costs") associated with any environmental
conditions identified in connection with the removal or upgrading of any
existing underground storage tanks identified on Schedule 2.12(c) (except for
the cost of removing, upgrading or installing such tanks) not meeting the
December 1998 RCRA technical requirements for such tanks except for conditions
resulting from Releases occurring after the Closing; provided, however, that
with respect to Sections 8.1(v)(A) and (B) above, Sellers shall only be
responsible for such Losses which, individually or in the aggregate but
collectively for such Sections, exceed $50,000, and provided further that with
respect to Section 8.1(v)(C) above, the Surviving Corporation shall be
responsible for the first $100,000 of such Remediation Costs, Sellers shall be
responsible for the next $100,000 of Remediation Costs, and the parties shall
share equally all such Remediation Costs in excess of $200,000.

         8.2. The Surviving Corporation's Obligations to Indemnify. Subject to
the limitations and procedures contained in this Article VIII, from and after
the Closing, the Surviving Corporation shall indemnify, defend and hold harmless
each Seller and its affiliates, and their respective directors, officers,
employees and representatives (each, a "Seller Indemnified Party" and, together
with the Company Indemnified Parties, the "Indemnified Parties"), from and
against any and all Losses suffered, sustained, incurred or required to be paid
by any such Seller 


                                       50


Indemnified Party due to, based upon, arising out of or otherwise in respect of
(i) any inaccuracy in, or breach of, any representation or warranty of BRS or
Newco contained in this Agreement (or any certificate or other agreement
delivered by Newco hereunder), (ii) any breach of any covenant or agreement of
the Surviving Corporation, BRS or Newco contained in this Agreement and (iii)
the enforcement by any Seller Indemnified Party of its rights under this
Agreement.

         8.3. Notice and Opportunity to Defend. The obligations and liabilities
of any party hereto against which indemnification is sought hereunder with
respect to claims resulting from the assertion of liability by third parties
shall be subject to this Section 8.3.

                (a) Promptly after receipt by any Indemnified Party of notice of
any demand or claim or the commencement (or threatened commencement) of any
action, proceeding or investigation (an "Asserted Liability") that could
reasonably be expected to result in a Loss, the Indemnified Party shall give
notice thereof (a "Claims Notice") to any other party obligated to provide
indemnification pursuant to Section 8.1 or 8.2 (each, an "Indemnifying Party").
Each Claims Notice shall describe the Asserted Liability in reasonable detail,
and shall indicate the amount (estimated, if necessary) of the Loss that has
been or may be suffered by the Indemnified Party. The rights of any Indemnified
Party to be indemnified hereunder shall not be adversely affected by its failure
to give, or its failure to timely give, a Claims Notice with respect thereto
unless, and if so, only to the extent that, the Indemnifying Party is materially
prejudiced thereby.

                (b) The Indemnifying Party may elect to compromise or defend, at
its own expense and by its own counsel, any Asserted Liability if (i) the claim
involves (and continues to involve) solely monetary damages and the Indemnifying
Party's assumption of the defense or settlement of such claim will not have a
material adverse effect on the Indemnified Party's business, (ii) the
Indemnifying Party states in writing to the Indemnified Party the Indemnifying
Party's good faith belief (based on the facts then known by the Indemnifying
Party) that, as between the two, the Indemnifying Party is solely obligated to
satisfy and discharge the claim, and (iii) the Indemnifying Party makes
reasonably adequate provision to satisfy the Indemnified Party of the
Indemnifying Party's ability to satisfy and discharge the claim (the foregoing
collectively, the "Litigation Conditions"); provided, however, that if the
parties in any action shall include both an Indemnifying Party and an
Indemnified Party, and the Indemnified Party shall have received written advice
of counsel that counsel selected by the Indemnifying Party has a conflict of
interest under applicable standards of professional responsibility because of
the availability of different or additional defenses to the Indemnified Party,
the Indemnified Party shall have the right to select one separate counsel to
participate in the defense of such action on its behalf, at the expense of the
Indemnifying Party; and provided further, however, that the Indemnifying Party
shall forfeit the right to control the defense or settlement of any such claim
if, at any time after assuming the defense or settlement thereof, the
Indemnifying Party no longer satisfies the Litigation Conditions. Subject to the
foregoing, if the Indemnifying Party elects to compromise or defend such
Asserted Liability, it shall within thirty (30) days (or sooner, if the nature
of the Asserted Liability so requires) notify the Indemnified Party of its
intent to do so, and the Indemnified Party shall cooperate, at the expense of
the Indemnifying Party, in the compromise of, or defense against, such Asserted
Liability. If the Indemnifying Party elects not to compromise or defend (or, as
provided below, discontinues its defense of) the Asserted Liability, fails to
notify the Indemnified Party of its election as herein provided, or fails to
satisfy the Litigation Conditions, the 


                                       51


Indemnified Party may pay, compromise or defend such Asserted Liability. Either
of the Indemnified Party or the Indemnifying Party may participate, at its own
expense (except as provided in the first sentence of this subparagraph (b)), in
the defense of an Asserted Liability being controlled by the other party.
Notwithstanding the foregoing, if, subsequent to the Indemnifying Party's
satisfaction of the Litigation Conditions and election to compromise or defend
an Asserted Liability, the Indemnifying Party can demonstrate to the reasonable
satisfaction of the Indemnified Party, based on facts not available to the
Indemnifying Party at the time of the original satisfaction of the Litigation
Conditions, that the Indemnifying Party is not obligated to satisfy or discharge
such claim, then Indemnifying Party may elect to discontinue the defense or
settlement of the Asserted Liability and the Indemnified Party may elect to
assume the defense or settlement of the Asserted Liability at the Indemnified
Party's expense. If the Indemnifying Party chooses to defend any claim, the
Indemnified Party shall, subject to receipt of a reasonable confidentiality
agreement, make available to the Indemnifying Party any books, records or other
documents within its control, and the reasonable assistance of its employees,
for which the Indemnifying Party shall be obliged to reimburse the Indemnified
Party the reasonable out-of-pocket expenses of making them available. If the
Indemnifying Party elects to discontinue the defense or settlement of an
Asserted Liability and the Indemnified Party elects to assume such defense or
settlement, the Indemnifying Party shall, subject to the receipt of a reasonable
confidentiality agreement, make available to the Indemnified Party any books,
records or other documents within its control, and shall provide to the
Indemnified Party the work product of the litigation or proceeding related to
such defense or settlement (except for books, records, documents and work
product (or portions thereof) relating solely to the Indemnifying Party's
liability for the relevant claim and the provision of which, based on opinion of
counsel, would prejudice the Indemnifying Party's defense of any action by the
Indemnified Party under this Article VIII).

                (c) The Indemnifying Party and the Indemnified Party shall use
commercially reasonable efforts to cooperate in determining the validity of any
third party claim for any Loss for which a claim for indemnification may be made
hereunder. Each party shall use commercially reasonable efforts to minimize all
Losses.

         8.4. Procedure for Claims by Parties. In the event that any party
incurs or suffers any Losses with respect to which indemnification may be sought
by such party pursuant to this Article VIII (other than in respect of third
party claims), the Indemnified Party must assert the claim by a Claims Notice to
the Indemnifying Party. The Claims Notice must state the nature and basis of the
claim in reasonable detail based on the information available to the Indemnified
Party. Each Indemnifying Party to whom a Claims Notice is given shall respond to
any Indemnified Party that has given a Claims Notice (a "Claim Response") within
thirty (30) days (the "Response Period") after the date that the Claims Notice
is given. Any Claim Response shall specify whether or not the Indemnifying Party
given the Claim Response disputes the claim described in the Claims Notice. If
any Indemnifying Party fails to give a Claim Response within the Response
Period, such Indemnifying Party shall be deemed not to dispute the claim
described in the related Claims Notice. If any Indemnifying Party elects not to
dispute a claim described in a Claims Notice, whether by failing to give a
timely Claim Response or otherwise, then the amount of such claim shall be
conclusively deemed to be an obligation of such Indemnifying Party, unless the
amount of the Loss actually suffered by the Indemnified Party differs from the
amount of the claim (whether 


                                       52


by change of circumstance, mistake or fraud of the Indemnified Party or
otherwise). If any Indemnifying Party shall be obligated to indemnify an
Indemnified Party hereunder, such Indemnifying Party shall pay to such
Indemnified Party the amount to which such Indemnified Party shall be entitled
within thirty (30) days after the last day of the applicable Response Period or,
if the Claims Notice relates to Losses that have not been liquidated as of the
date of the Claims Notice, the date on which all or any part of such Losses
shall have become liquidated and determined. If there shall be a dispute as to
the amount or manner of indemnification under this Agreement, the Indemnifying
Party and the Indemnified Party shall seek to resolve such dispute through
negotiations and, if such dispute is not resolved within twenty (20) days, the
Indemnified Party may submit such dispute to arbitration pursuant to Section
10.9. If any Indemnifying Party fails to pay all or any part of any
indemnification obligation on or before the later to occur of (y) thirty (30)
days after the last day of the applicable Response Period, and (z) if the Claims
Notice relates to Losses that have not been liquidated as of the date of the
Claims Notice, the date on which all or any part of such Losses shall have
become liquidated and determined, then the Indemnifying Party shall also be
obligated to pay to the Indemnified Party interest on the unpaid amount for each
day during which the obligation remains unpaid at an annual rate established in
the manner described in Section 1.10(g).

         8.5. Limitations on Indemnification. The indemnification provided for
in Sections 8.1 and 8.2 shall be subject to the following limitations:

                (a) The Sellers shall not be obligated to pay any
indemnification amounts for Losses pursuant to Section 8.1(i) until the
aggregate amount of all Losses pursuant thereto exceeds an amount equal to
$3,000,000 (the "Basket"), whereupon the Company Indemnified Parties shall be
entitled to indemnification under Section 8.1(i) for all such Losses in excess
of such amount, up to a maximum amount equal to $50,000,000, subject to
paragraph (d) below. In addition, no claim shall be made for Losses with respect
to any breach of a representation or warranty under Section 8.1(i) unless the
claim for Losses with respect to such breach reasonably could be expected to
exceed $50,000; provided, however, that any breaches arising out of a series of
related events or the same set of operative facts shall be treated as a single
claim for purposes of this paragraph (a).

                (b) No claims for indemnification in respect of Sections 8.1(i)
or 8.2(i) shall be made after the date on which the applicable representation or
warranty upon which such claim was based ceases to survive pursuant to Section
8.7; provided that the expiration of any representation or warranty under
Section 8.7 shall not affect any claim made pursuant to a Claims Notice
delivered prior to the date of such expiration.

                (c) The limitations on the indemnification obligations set forth
in this Section 8.5 shall not apply to any covenants of the Sellers (or any
other party) in this Agreement (including covenants in Article II and Article
III, except to the extent that any representations or warranties are contained
within such covenants). In addition, notwithstanding the provisions of paragraph
(a) above, the limitations on the indemnification obligations of Sellers set
forth in paragraph (a) above shall not apply to breaches of the representations
and warranties made in Sections 2.1 (other than the second sentence of Section
2.1(a)), 2.2 (other than in Section 2.2(b) 


                                       53


with respect to the qualification or licensing of the Subsidiaries as foreign
corporations), 2.3, 3.1 and 3.2.

                (d) Notwithstanding anything to the contrary set forth herein,
no limitation or condition of liability or indemnity applicable to any Seller
shall apply to any breach of a representation or warranty if such representation
or warranty was made with actual knowledge by such Seller that it (i) contained
an untrue statement of a material fact or (ii) omitted to state a material fact
necessary to make the statements contained therein not misleading. For purposes
of calculating the amount of Losses incurred arising out of or relating to any
breach of a representation or warranty by any Seller, the references to
"Material Adverse Effect" or "Material Adverse Change" or other materiality
qualifications (or correlative terms), including as expressed in accounting
concepts such as GAAP, shall be disregarded.

                (e) The Company Indemnified Parties may seek recovery against
any Seller for any Loss for which the Sellers are jointly and severally liable
hereunder, except that (i) in any action (including any arbitration pursuant to
Section 10.9) to recover such Loss, the appropriate Company Indemnified Parties
may not proceed against any Seller unless (subject to jurisdictional, venue or
other procedural limitations) it also proceeds against each of the Roger C.
Stull and Ann R. Stull Trust, the NCCF, John Sawyer, J&J Investments, LLC, the
Repchinuck Revocable Trust, C. George Bush and Bruce Varney; (ii) the Servants'
Trust shall not be liable for any portion of the Pro Rata Share of the Roger C.
Stull and Ann R. Stull Trust, the Gregory J. Stull Family Trust, the Kevin C.
McTavish Family Trust, the Christine Marie Stull Family Trust or Nicole Lynn
Stull of such Loss, and J&J Investments, LLC shall not be liable for any portion
of the Pro Rata Share of John Sawyer of such Loss; (iii) the Management
Stockholders, Floyd E. Skor, the Charles D. Steichen and Martha L. Steichen
Trust, as a group shall not be liable for more than their aggregate Pro Rata
Share of such Loss; (iv) B-R Investors/Penhall I, L.P. shall not be liable for
more than its Pro Rata Share of such Loss; (v) the liability of each Management
Stockholder (other than John Sawyer, J&J Investments, LLC, the Repchinuck
Revocable Trust, C. George Bush and Bruce Varney) shall be limited to his or its
Eligible Assets (as defined in Section 8.5(g)); and (vi) no Non-Defaulting
Seller (as defined in Section 8.5 (f)) who is a Non-Management Stockholder, and
none of John Sawyer, J&J Investments, LLC, the Repchinuck Revocable Trust, C.
George Bush or Bruce Varney, shall be liable for any Management Stockholder's
Pro Rata Share of such Loss until the appropriate Company Indemnified Parties
have attempted in good faith, through appropriate judicial or other proceedings,
to recover indemnification payments from such Management Stockholder under
Section 8.1 for the full amount of such Management Stockholder's Eligible
Assets.

                (f) The Sellers agree among themselves that each Seller shall
pay such Seller's Pro Rata Share of any Loss, other than a Loss arising out of a
breach of a representation or warranty by another Seller under Article III or a
breach of a covenant by another Seller for which the breaching Seller is solely
liable hereunder; provided, however, subject to the limitations of Section
8.5(e), if any Seller (a "Defaulting Seller") fails to pay any or all of his or
its Pro Rata Share of such Loss, each remaining Seller (a "Non-Defaulting
Seller") shall also pay a fraction of the shortfall of such Loss equal to such
Non-Defaulting Seller's Pro Rata Share divided by the aggregate Pro Rata Share
of all Non-Defaulting Sellers. Each Defaulting Seller shall indemnify, defend
and hold harmless the Non-Defaulting Sellers from any Losses incurred by the
Non-


                                       54


Defaulting Sellers that are caused by the failure of such Defaulting Seller to
pay such Defaulting Seller's Pro Rata Share of any Losses to the extent required
herein. Each Seller acknowledges it is his or its intent, as a material part of
the consideration for the execution of this Agreement, that each Seller shall be
liable to pay such Seller's Pro Rata Share of any Losses to the extent provided
herein. At the Closing, each Management Stockholder shall grant a security
interest in the shares of the Surviving Corporation stock received as Merger
Consideration, and the proceeds thereof, to the Surviving Corporation in respect
of such Management Stockholder's obligations under this Article VIII by
executing a pledge agreement containing terms and conditions reasonably
satisfactory to the Surviving Corporation (including without limitation the full
subordination of such pledge to the Surviving Corporation's rights under the
Securities Holders Agreement) (the "Pledge Agreement").

                (g) Each Management Stockholder may, at his or its option,
satisfy any indemnification obligation under Section 8.1 by payment of cash or
by delivery to the Surviving Corporation of shares of stock of the Surviving
Corporation, which shares shall have a Current Market Value determined in
accordance with Section 8.5(h); provided, however, that if any Management
Stockholder elects to satisfy such indemnification obligation by payment of
cash, such Management Stockholder must make such election irrevocably by written
notice to the Surviving Corporation before the commencement of any determination
of Fair Market Value under Section 8.5(h), of which commencement the Surviving
Corporation will give ten (10) days prior notice. Other than pursuant to the
Securities Holders Agreement, but subject to the terms of the Pledge Agreement,
no cash shall be paid to a Management Stockholder upon the occurrence of any
event requiring the redemption from such Management Stockholder of shares of
Surviving Corporation stock received as Merger Consideration, and, other than
pursuant to the Securities Holders Agreement, but subject to the terms of the
Pledge Agreement, no Management Stockholder shall otherwise be permitted to
transfer any shares of Surviving Corporation stock received as Merger
Consideration or receive cash or other property in respect of such shares,
unless such Management Stockholder first provides security reasonably
satisfactory to BRS and the Seller Representative for such Management
Stockholder's indemnification obligations under this Agreement in the full
amount of his or its Eligible Assets. For purposes of this Agreement, a
Management Stockholder's "Eligible Assets" shall include (i) all shares of stock
of the Surviving Corporation received by such Management Stockholder as Merger
Consideration, (ii) all cash and other property received by such Management
Stockholder in connection with any transfer or redemption of such shares, and
(iii) all cash and other property (including other securities of the Surviving
Corporation or any other entity) received by such Management Stockholder in
respect of such shares, whether by way of dividend, merger, reorganization,
recapitalization, or otherwise.

                (h) For purposes of this Agreement, "Current Market Price" on
any date shall mean, with respect to any security, if such security is publicly
traded in the United States, the average of the daily Closing Prices for the ten
(10) consecutive trading days ending on the date immediately prior to the date
as of which the Current Market Price is to be determined, or, if such day is not
a trading date, the trading day immediately preceding such date. The "Closing
Price" for each day shall be the average of the closing bid and asked price for
such security on the NASDAQ National Market System, or, if not then traded
thereon, the last reported sale price regular way or, in case no such reported
sale takes place on such day, the average of the reported closing bid and asked
price regular way on the principal stock exchange on which such security is 


                                       55


then listed or traded, or, if not then listed or traded on any such exchange,
the mean of the closing bid and asked prices on an automated quotation system as
furnished by any New York Stock Exchange member firm selected from time to time
by the Surviving Corporation for that purpose. Except as set forth in the
preceding sentence, with respect to any security that is not publicly traded in
the United States, "Current Market Price" on any date shall mean the fair market
value of such security on such date as determined by mutual agreement of BRS,
John Sawyer and the Seller Representative, or, if they are unable to agree, by
an independent appraiser selected by the Surviving Corporation and reasonably
acceptable to John Sawyer and the Seller Representative. The costs of any such
appraiser shall be paid by the Surviving Corporation.

                (i) The parties further agree that the NCCF may, at its option,
satisfy any indemnification obligation under Section 8.1 by payment of cash or
by delivery to the Surviving Corporation of shares of Senior Exchangeable
Preferred Stock in an aggregate Liquidation Preference (as defined in the
statement of designation thereof attached hereto as Exhibit N), plus accrued but
unpaid dividends thereon, equal to the amount of such indemnification obligation
or Junior Subordinated Notes, for which shares of the Senior Exchangeable
Preferred Stock are exchangeable, in an aggregate principal amount, plus accrued
but unpaid interest thereon, equal to the amount of such indemnification
obligation. This Section 8.5(i), however, shall not limit in any other way the
NCCF's indemnification obligations under Article VIII, including without
limitation the obligation to satisfy indemnification obligations in cash in the
event that the NCCF no longer shall hold any shares of the Senior Exchangeable
Preferred Stock or any such Junior Subordinated Notes.

                (j) Each Seller agrees that neither it nor any of the other
Sellers is a necessary or indispensable party for any action (including an
arbitration pursuant to Section 10.9) for the purpose of determining whether the
Company Indemnified Parties are entitled to indemnification for any Losses
pursuant to this Agreement, hereby waives, to the fullest extent permitted by
law, any requirement that the Company Indemnified Parties join such Seller in,
or provide such Seller with notice of, any such action and hereby agrees not to
file a motion to dismiss, vacate, stay or transfer such action by reason of a
Company Indemnified Party's failure to join any Seller as a party to such
action. Notwithstanding the foregoing, the Company Indemnified Parties (i) shall
give notice of such action to the Seller Representative and the Sellers to the
extent required by the other provisions of this Agreement, (ii) shall name in
such action the persons specified in clause (i) of Section 8.5(e), and (iii)
shall not oppose the joinder of any of the Sellers, if not named as a party in
any such action brought by any Company Indemnified Party against one or more of
the Sellers pursuant to this Agreement, as a party to such action, upon any of
such Sellers' written request; provided, however, any failure of the Company
Indemnified Parties to give notice of any such action to any of the Sellers
(other than the Seller Representative) or of any of the Sellers to actually
receive such notice shall not affect the validity of the agreements and waivers
of each Seller set forth in the first sentence of this Section 8.5(i). Each
Seller also agrees that service of process or any other legal process for any
action brought by the Company Indemnified Parties pursuant to this Agreement may
be made as set forth in Section 9.1(b) of this Agreement. Each Seller agrees
that any of the other Sellers may join or be joined in any such action in which
such Seller has been named as an Indemnifying Party by the Company Indemnified
Parties, or in which such Seller has joined in the action.


                                       56


                (k) Notwithstanding anything in this Agreement to the contrary,
none of the Sellers shall have any liability on account of a breach or
inaccuracy in a representation or warranty pursuant to Section 8.1(i), to the
extent that (A) the matter or event which causes the inaccuracy or breach first
arose prior to the Closing Date (either before or after the date of this
Agreement), (B) neither any Seller nor the Company had knowledge of such matter
or event as of the date of the Original Agreement, (C) such matter or event is
disclosed to BRS and Newco in the revised disclosure Schedules delivered
pursuant to Section 6.4 and (D) BRS and Newco shall have elected to proceed with
the Closing.

                (l) The parties agree that: (i) in the event that the Roger C.
Stull and Ann R. Stull Trust, the Servants' Trust or the NCCF shall be obligated
to make any indemnification payments under this Article VIII ("Stull
Indemnification Payments"), such Stull Indemnification Payments shall not be
payable until the sooner of such time as (x) Roger C. Stull and Ann R. Stull
shall have been released from their obligations under that certain Agreement of
Indemnity, dated January 7, 1991 (the "Fidelity Agreement"), among Roger C.
Stull, Ann R. Stull, Penhall, Penhall Company, PCC, Penhall Environmental
Services and Fidelity and Deposit Company of Maryland ("Fidelity") and (y) all
of the bonding obligations of Fidelity that are the subject of the Fidelity
Agreement shall have expired or have been terminated, and no interest shall
accrue with respect to such Stull Indemnification Payments prior to such time,
provided, that no such deferral of the Stull Indemnification Payments shall
result in an increase in the amounts payable by any other Seller under this
Article VIII; (b) the Roger C. Stull and Ann R. Stull Trust shall be entitled to
offset any amounts actually paid by Roger C. Stull and Ann R. Stull (together
with their affiliates, the "Stulls") from and after the Closing under the
Fidelity Agreement against any Stull Indemnification Payments required to be
made by it; and (c) the Surviving Corporation will indemnify, defend and hold
harmless the Stulls from and against any Losses incurred by them under the
Fidelity Agreement.

         8.6. Insurance and Tax Effect. (a) Any payments made pursuant to the
provisions of this Article VIII shall be treated as an adjustment to the total
consideration payable to the Sellers under this Agreement.

                (b) The amount of any Loss for which indemnification is provided
under any of Sections 8.1 or 8.2 shall be net of any amounts (net of the costs
of recovery of such amounts) recovered by the Indemnified Party under insurance
policies with respect to such Loss (collectively, a "Net Loss").

                (c) The amount of any Loss shall be (i) increased to take
account of the net Tax cost (if any) actually incurred by the Indemnified Party
arising from the receipt of indemnity payments hereunder (grossed up for such
increase) and (ii) reduced to take account of any net Tax benefit (if any)
actually realized by the Indemnified Party arising from the incurrence or
payment of any such Net Loss.

         8.7. Survival of Representations and Warranties. The provisions set
forth in Section 10.5 of this Agreement shall expressly survive the termination
or abandonment of this Agreement. All covenants and agreements contained in this
Agreement shall survive the Closing Date in perpetuity and shall remain in full
force and effect in accordance with their terms. The 


                                       57


representations and warranties set forth in Articles II, III and IV of this
Agreement (and any Schedule thereto) shall survive the Closing Date for a period
of eighteen (18) months, except (a) the representations in Section 2.8 (and any
Schedules thereto) shall survive until the date which is 60 days after the
expiration of the statute of limitations applicable to such matters, (b) the
representations and warranties in Sections 2.12 and 2.20 (and any Schedules
thereto) shall survive the Closing Date for a period of five (5) years, (c) the
representations and warranties in Sections 2.1 - 2.4, Article III and Sections
4.1 and 4.2 (and any Schedules thereto) shall survive the Closing Date in
perpetuity, and (d) the foregoing time limitations shall not apply to any claims
which have been the subject of a Claims Notice prior to expiration of the
applicable time period. Subject to Section 8.5(j), no right of indemnification
hereunder shall be limited by reason of any investigation or audit conducted
before or after the Closing or the knowledge of any party of any breach of a
representation, warranty, covenant or agreement by the other party at any time,
or the decision of any party to complete the Closing.

                                   ARTICLE IX

                      APPOINTMENT OF SELLER REPRESENTATIVE

         9.1 Appointment of the Seller Representative; Enforcement of Rights,
Benefits and Remedies. (a) Each Seller hereby irrevocably constitutes and
appoints Roger C. Stull as the Seller Representative for the purpose of
performing and consummating the transactions contemplated by this Agreement. The
appointment of Roger C. Stull as the Seller Representative is coupled with an
interest and all authority hereby conferred shall be irrevocable and shall not
be terminated by any or all of the Sellers without the consent of Newco (or,
after the Closing, the Surviving Corporation), which consent may be withheld for
any reason, and the Seller Representative is hereby authorized and directed to
perform and consummate all of the transactions contemplated by this Agreement.
Not by way of limiting the authority of the Seller Representative, each and all
of the Sellers, for themselves and their respective heirs, executors,
administrators, successors and assigns, hereby authorize the Seller
Representative to:

                    (i) waive any provision of this Agreement which the Seller
Representative deems necessary or desirable;

                    (ii) execute and deliver on their behalf all documents and
instruments which may be executed and delivered pursuant to this Agreement,
including without limitation the shares of Existing Company Stock, Penhall Class
A Common Stock, Penhall Class B Common Stock, Class A Common Stock, Class B
Common Stock or Class C Common Stock and the stock powers with respect thereto;

                    (iii) make and receive notices and other communications
pursuant to this Agreement and service of process in any legal action or other
proceeding arising out of or related to this Agreement or any of the
transactions hereunder;

                    (iv) settle any dispute, claim, action, suit or proceeding
arising out of or related to this Agreement or any of the transactions
hereunder;


                                       58


                    (v) receive and distribute the Seller Consideration and
adjustments thereto;

                    (vi) appoint or provide for successor agents; and

                    (vii) pay expenses incurred or which may be incurred by or
on behalf of the Sellers in connection with this Agreement.

In the event of the inability, failure or refusal of Roger C. Stull to act as
the Seller Representative, or in the event of the death of Roger C. Stull or any
successor, the Sellers promptly shall appoint one of the Sellers as their agent
for purposes of this Article IX by action of Sellers who held a majority in
interest of the shares of Existing Company Stock. Failing such an appointment
within thirty (30) days of such inability, failure, refusal or death, Newco (or,
after the Closing, the Surviving Corporation) may, by written notice to the
Sellers at the last address of the Sellers applicable for purposes of Section
10.3 hereof, designate one of the Sellers as the Seller Representative.

                (b) Any claim, action, suit, or other proceeding, whether in law
or equity, to enforce any right, benefit or remedy granted to the Sellers under
this Agreement may be asserted, brought, prosecuted or maintained only by the
Seller Representative. Any claim, action, suit or other proceeding, whether in
law or equity, to enforce any right, benefit or remedy granted under this
Agreement, including without limitation any right of indemnification provided in
Article VIII hereof, may be asserted, brought, prosecuted or maintained by a
Company Indemnified Party against the Sellers or the Seller Representative by
service or process on the Seller Representative and without the necessity of
serving process on, or otherwise joining or naming as a defendant in such claim,
action, suit or other proceeding, any Seller. With respect to any matter
contemplated by this Article IX, the Sellers shall be bound by any determination
in favor of or against the Seller Representative or the terms of any settlement
or release to which the Seller Representative shall become a party.

                (c) The Seller Representative shall not be liable to any Seller
for any acts or omissions of the Seller Representative in connection with his
duties and obligations hereunder, except in the case of the Seller
Representative's gross negligence or willful misconduct. The Sellers (excluding
the Seller Representative and his affiliates), jointly and severally, agree to
indemnify and hold the Seller Representative harmless as to any liability (other
than on account of his respective indemnification obligations under Article
VIII) incurred by him to any person by reason of his having accepted the same or
in carrying out any of the terms hereof, and to reimburse the Seller
Representative for all of his costs and expenses, including, among other things,
reasonable attorneys' fees and costs, incurred by reason of any matter as to
which an indemnity is paid under this Section 9.1(c); provided, however, that no
indemnity need be paid in the case of the Seller Representative's gross
negligence or willful misconduct.


                                       59


                                    ARTICLE X

                                  MISCELLANEOUS

         10.1. Amendment and Modification. This Agreement may be amended,
modified supplemented or altered only by a written agreement signed by the
parties hereto at any time prior to the Closing with respect to any of the terms
contained herein.

         10.2. Waiver of Compliance; Consents. Any failure of a party to comply
with any obligation, covenant, agreement or condition herein may be waived, but
only if such waiver is in writing and is signed by the party against whom the
waiver is to be effective. Such waiver or failure to insist upon strict
compliance with such obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure. Whenever this Agreement requires or permits consent by or on behalf of
any party hereto, such consent shall be given in writing in a manner consistent
with the requirements for a waiver of compliance as set forth in this Section
10.2.

         10.3. Notices. All notices and other communications hereunder shall be

         10.4. Assignment; No Third Party Beneficiaries. This Agreement and all
of the provisions hereof shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns, but
neither this Agreement nor any of the rights, interests or obligations hereunder

of the other parties hereto; provided that the Company or the Surviving
Corporation may assign its rights and obligations to any lender providing
financing in connection with the transactions contemplated hereby (or in

part thereof); provided that no such assignment shall relieve BRS or the

confer upon any person (including, without limitation, any employees) other than
the parties hereto and their respective successors and permitted assigns, and
rights or remedies hereunder.

         10.5. Expenses. Except as otherwise expressly provided herein, each of
the parties hereto will bear its own expenses in connection with the
negotiation, preparation, execution and delivery of this Agreement and the
documents and instruments contemplated hereby and in connection with the
transactions contemplated hereby and thereby, including all fees and
disbursements of counsel, accountants, appraisers and other advisors retained by
such party; 


                                       61


provided, however, that if the transactions contemplated by this Agreement are
consummated, (i) Roger C. Stull will pay a portion of the fees payable to
William L. Rogers and his affiliates (the "Rogers Fee") in an amount equal to
the product of the Rogers Fees multiplied by the Non-Management Stockolders'
(excluding Floyd E. Skor, B-R Investors/Penhall I, L.P. and the Charles D.
Steichen and Martha L. Steichen Trust) pre-Closing ownership percentage of
Existing Company Stock (without giving effect to the transactions under the
Exchange) and (ii) except as provided in the immediately preceding clause (i),
the Surviving Corporation shall bear the expenses of the Sellers, BRS and Newco
in addition to its own expenses. In addition, the financial cost to BRS of the
dilution from certain of the Surviving Corporation's post-Closing management
stock arrangements, in the aggregate amount of $995,922, shall be borne
one-third by the Roger C. Stull and Ann R. Stull Trust, one-third by BRS and
one-third by the Management Stockholders. The Roger C. Stull and Ann R. Stull
Trust's share of such cost, $331,974, shall be subtracted from the Cash Merger
Consideration payable to it at Closing in full satisfaction of its obligations
under the preceding sentence.

         10.6. Governing Law. This agreement, and all agreements, documents and
instruments delivered pursuant to hereto incorporated herein, unless otherwise
expressly provided therein, shall be governed by, and construed in accordance
with, the substantive laws of the State of California applicable to agreements
made and to be performed entirely within such state, without reference to the
conflicts of laws rules of such state.

         10.7. Counterparts. This Agreement may be executed by the parties
hereto individually or in any combination, in one or more counterparts, each of
which shall be deemed an original and all of which shall together constitute one
and the same instrument.

         10.8. Entire Agreement. This Agreement, including the documents and
instruments referred to herein or contemplated hereby, embodies the entire
agreement and understanding of the parties hereto in respect of the subject
matter hereof. There are no restriction, promises, representations, warranties,
covenants or undertakings, other than those expressly set forth or referred to
herein. Except for that certain Letter Agreement (regarding confidentiality)
dated March 13, 1998 between the Company and BRS, this Agreement supersedes all
prior agreements and understandings between the parties with respect to the
subject matter hereof.

         10.9. Arbitration. (a) If any dispute or controversy shall arise among
the parties hereto as to any matter arising out of or in connection with this
Agreement, the parties shall attempt in good faith to resolve such controversy
by mutual agreement. If such dispute or controversy cannot be so resolved, it
shall be resolved solely in accordance with the provisions of this Section 10.9.

                (b) Any dispute, controversy or claim between or among the
parties to this Agreement (the "Disputing Parties") arising out of or related to
this Agreement, or the breach thereof, shall be settled by a single arbitrator
by arbitration, conducted in the State of California, in accordance with the
Commercial Rules of the American Arbitration Association (the "AAA"). Such
arbitration shall be administered by the AAA only if one (or more) of the
Disputing Parties requests such administration. Arbitration shall be the
exclusive remedy for determining any such 


                                       62


dispute, regardless of its nature. Unless mutually agreed by the parties
otherwise, any arbitration shall take place in the City of Los Angeles,
California.

                (c) The arbitrator shall be selected by the Disputing Parties
within fifteen (15) days after demand for arbitration is made by a Disputing
Party. If the Disputing Parties are unable to agree on an arbitrator within such
period, then each Disputing Party shall select one arbitrator, and each such
arbitrator shall select a third arbitrator and the dispute shall be settled by
the panel consisting of such three arbitrators (such panel, or the single
arbitrator agreed to by both parties, as the case may be, being hereinafter
referred to as the "Arbiter"). Each arbitrator shall be an attorney licensed in
the State of California and shall possess substantive legal experience with
respect to the principal issues on dispute.

                (d) This agreement to resolve any disputes by binding
arbitration shall extend to claims against any parent, subsidiary or affiliate
of each party, and when acting within such capacity, any officer, director,
shareholder, employee or agent of each party, or of any of the above, and shall
apply as well to claims arising out of state and federal statutes and local
ordinances as well as to claims arising under the common law. In the event of a
dispute subject to this paragraph the Disputing Parties shall be entitled to
reasonable discovery subject to the discretion of the Arbiter. The remedial
authority of the Arbiter shall be the same as, but no greater than, would be the
remedial power of a court having jurisdiction over the parties and their
dispute. In the event of a conflict between the Commercial Rules of the AAA and
these procedures, the provisions of these procedures shall govern.

                (e) Except as may otherwise be agreed to in writing by the
Disputing Parties or as ordered by the Arbiter upon substantial justification,
the hearings of the dispute shall be held and concluded within ninety (90) days
of submission of the dispute to arbitration. The Arbiter shall render its final
award within thirty (30) days following closing of the record. The Arbiter shall
state the factual and legal basis for the award. The decision of the Arbiter
shall be final and binding, and no appeal shall be permitted therefrom. Final
judgment may be entered upon such an award in any State or Federal court having
the arbitration jurisdiction thereof, but entry of such judgment shall not be
required to make such award effective.

                (f) Any filing or administration fees shall be borne initially
by the Disputing Party requesting administration by the AAA. If more than one
Disputing Party requests such administration, the fees shall be borne initially
by the party incurring such fees as provided by the rules of the AAA. The
initial fees and costs of the Arbiter shall be borne equally between the
Disputing Parties. The prevailing party in such arbitration, as determined by
the Arbiter, and in any enforcement or other court proceedings, shall be
entitled to the extent permitted by law, to reimbursement from the other party
for all of the prevailing party's costs (including but not limited to the
Arbiter's compensation), expenses, and attorneys' fees.

                (g) Nothing in this Section 10.9 shall limit any right that any
party may otherwise have to seek to obtain (i) preliminary injunctive relief in
order to preserve the status quo pending the disposition of any such arbitration
proceeding or (ii) temporary or permanent injunctive relief from any breach of
any provision of this Agreement.


                                       63


         10.10. Severability. If any provision or provisions of this Agreement
or of any of the documents or instruments delivered pursuant hereto, or any
portion of any provision hereof or thereof, shall be deemed invalid or
unenforceable pursuant to a final determination of any court of competent
jurisdiction or as a result of future legislative action, such determination or
action shall be construed so as not to affect the validity or enforceability
hereof or thereof and shall not affect the validity or effect of any other
portion hereof or thereof.

         10.11. Arm Length Contract. This Agreement has been negotiated "at arms
length" by the parties, each represented by counsel of its choice and each
having an equal opportunity to participate in the drafting of the provisions
hereof. Accordingly, in construing the provisions of this Agreement no party
shall be presumed or deemed to be the "drafter" or "preparer" of the same.

         10.12. Headings; Interpretative Provisions. (a) The headings of the
various Articles and Sections of this Agreement have been inserted for the
purpose of convenience of reference only, and shall not be deemed in any manner
to modify, explain, enlarge or restrict any of the provisions of this Agreement.

                (b) When reference is made in this Agreement to an Article or
Section or Schedule, such reference shall be to an Article, Section or Schedule
of this Agreement unless otherwise indicated. Whenever the words "included",
"includes" or "including" (or any other tense or variation of the word
"include") are used in this Agreement, they shall be deemed to be followed by
the words "without limitation". As used in this Agreement, the auxiliary verbs
"will" and "shall" are mandatory, and the auxiliary verb "may" is permissive
(and, by extension, is prohibitive when used negatively, as a denial of
permission). All accounting terms used but not otherwise defined in this
Agreement shall have the meanings determined by GAAP. The words "hereof",
"herein" and "hereunder" and words of similar import when used in this Agreement
shall refer to this Agreement as a whole and not to any particular provision of
this Agreement. The definitions contained in this Agreement are applicable to
the singular as well as to the plural forms of such terms and to the masculine
as well as to the feminine and neuter genders of such term. Any agreement,
instrument or statute defined or referred to herein or in any document or
instrument that is referred to herein means such agreement, instrument or
statute as from time to time amended, modified or supplemented, including (in
the case of agreements or instruments) by waiver or consent and (in the case of
statutes) by succession of comparable successor statutes.

                (c) Whenever a representation or warranty is stated to be based
on the "knowledge of the Company", the "Company's knowledge" or a similar
qualification, such phrase refers to whether any of the Company's Senior
Management (as hereafter defined) has actual knowledge, after due inquiry, of
the matters involved. For purposes of this Agreement, the Company's "Senior
Management" consists of C. George Bush, Martin Houge, David S. Neal, Robert
Norling, Renee O'Brien, Bruce Repchinuck, John Sawyer, Floyd Skor, Charles D.
Steichen, Roger C. Stull and Bruce Varney.

                (d) Any matter disclosed by the Company or the Sellers to BRS
and Newco in any disclosure Schedule shall be deemed to be disclosed with
respect to any other Schedule so 


                                       64


long as the relevance of the matter to such other Schedule is readily apparent
from the disclosure of the matter that appears in the Schedule where it is
disclosed.

                (e) Reasonable or Best Efforts. Whenever a covenant requires a
party to use its "best efforts," "reasonable efforts," "reasonable best efforts"
or "commercially reasonable efforts" to do something or cause something to
occur, such party shall be deemed to have performed such covenant if it used the
requisite efforts regardless of whether such efforts were successful.

         10.13. Time is of the Essence. Time is of the essence in the
performance of this Agreement.

         10.14. Golden Parachute Approval Requirement. Prior to execution of the
Compensation Agreement, the Sellers shall have caused the shareholder approval
requirements set forth in Section 280G(b)(5) of the Code to be satisfied with
respect to all payments incident to the transactions under the Compensation
Agreement to any "disqualified individual" as defined in Section 280G(c) of the
Code.

         10.15. Date of Representations and Warranties and Covenant Obligations.
Notwithstanding anything in this Agreement to the contrary, but without limiting
the conditions set forth in Sections 6.2(b) and 6.3(b), the representations and
warranties of the parties to this Agreement set forth in Articles II, III and IV
shall be deemed to have been given, and the Schedules to this Agreement
prepared, as of the date of the Original Agreement. No failure of a
representation or warranty herein to be true and correct as of the date of this
Agreement shall constitute a breach of this Agreement unless such failure
constituted a breach of the Original Agreement as of the date of the Original
Agreement. In addition, the covenants and agreements set forth in Article V
shall be deemed to have been made as of the date of the Original Agreement.
Without limiting the foregoing the terms "as of the date hereof," "as of the
date of this Agreement," "current," "currently" and other terms referring to a
specific date, as used in Articles II, III, IV and V hereof, shall refer to the
date of the Original Agreement.


                                       65


         IN WITNESS WHEREOF, each of the parties hereto has caused this
Agreement to be executed on its behalf as of the date first above written.
