agrees with, Penhall that:

              (a) Such Stockholder has full legal right, capacity, power and
authority (including the due authorization by all necessary corporate action in

                       OTHER COVENANTS AND REPRESENTATIONS
                       -----------------------------------

         3.1 Financial Statements and Other Information. So long as BRS owns any
of the Securities, Penhall shall deliver to BRS:

              (a) as soon as available and in any event within 45 days after the
end of each of the first three quarters of each fiscal year of Penhall,
consolidated balance sheets of Penhall and its subsidiaries as of the end of
such period, and consolidated statements of income and cash flows of Penhall and
its subsidiaries for the period then ended prepared in conformity with GAAP (as

end of each fiscal year of Penhall, a consolidated balance sheet of Penhall and
its subsidiaries as of the end of such year, and consolidated statements of

         3.2 Sale of Penhall or any of the Companies.
             ---------------------------------------

              (a) If the Board of Directors of Penhall and holders of at least a
majority of Penhall's Common Stock then outstanding approve the sale of Penhall
or any of the Companies to an unaffiliated third person (whether by merger,
consolidation, reorganization, sale of all or substantially all of its assets or
sale of a majority of the outstanding capital stock) (an "Approved Sale"), each
Stockholder and his or its transferees (including Permitted Transferees)
("Transferees") will consent to, vote for, and raise no objections against, and
waive dissenters and appraisal rights (if any) with respect to, the Approved
Sale, and will sell all of his or its Securities in such Approved Sale upon the
terms and conditions approved by the Board of Directors of Penhall and the
holders of a majority of the Common Stock then outstanding.


                                       5



Each Stockholder and Transferee will take all reasonably necessary and desirable
actions in connection with the consummation of an Approved Sale.

              (b) The obligations of each of the Stockholders and the
Transferees with respect to an Approved Sale are subject to the satisfaction of
the conditions that: (i) upon the consummation of the Approved Sale, all of the
Stockholders and the Transferees will receive the same form and amount of
consideration per share of the applicable Securities (and, for purposes of
clarification, the Series A Preferred Stock and the Series B Preferred Stock
shall be treated as the same applicable Security), or if any holder of
Securities is given an option as to the form and amount of consideration to be
received, all Stockholders and Transferees will be given the same option, (ii)
the terms of the Approved Sale shall not include any provisions subjecting a
Stockholder or its Transferees to any indemnification obligation or other
liability beyond the value of the consideration received in the Approved Sale by
such Stockholder or Transferees and (iii) all Stockholders and Transferees shall
be subject to the same form of indemnification obligation under the terms of the
Approved Sale.

         3.3 Tag-Along Rights.
             ----------------

              (a) Except as otherwise provided in Section 3.3(e), BRS and each
BRS Entity who or which receives shares from BRS after the date hereof as a BRS
Permitted Transferee covenant and agree with the other Stockholders and their
Transferees and assigns that it will not effect a Transfer of shares of Common
Stock and/or Preferred Stock in any transaction that constitutes a "Significant
Transfer" (as hereinafter defined) unless all other Stockholders and their
Transferees and assigns (collectively, the "Tag-Along Rightholders") are offered
an equal opportunity (the "Tag-Along Right") to participate in such transaction
or transactions on a pro rata basis (based on the number of shares of Common
Stock or Preferred Stock, as the case may be, outstanding on a fully-diluted
basis) and on identical terms. As used herein, a "Significant Transfer" means a
Transfer, which either alone or taken together with all prior Transfers by BRS
and BRS Entities to any person or persons other than a BRS Permitted Transferee
(as hereinafter defined), involves one-third (1/3) or more of the shares of
Common Stock or Preferred Stock held by BRS on the date hereof. A "BRS Permitted
Transferee" shall mean, (A) any other BRS Entity or other Stockholder, (B) any
general partner of a BRS Entity (a "BRS Partner") and any corporation,
partnership or other entity that is an Affiliate (as hereinafter defined) of any
BRS Entity or BRS Partner (collectively, "BRS Affiliates"), (C) any managing
director, director, general partner, limited partner, officer or employee of any
BRS Entity or any BRS Affiliate, or any spouse, lineal descendant or immediate
family member of any BRS Entity or any heir, executor, administrator,
testamentary trustee, legatee or beneficiary of a BRS Entity or any of the
foregoing persons


                                       6



described in this clause (C) (collectively, "BRS Associates") and (D) any trust,
the beneficiaries of which, or any corporation, limited liability company or
partnership, the stockholders, members or general and limited partners of which
include only BRS Entities, BRS Affiliates, or BRS Associates.

              (b) Prior to any sale of Common Stock and/or Preferred Stock
subject to the provisions of Section 3.3(a), the seller (the "Tag-Along Seller")
shall notify Penhall in writing of the proposed sale. Such notice (the
"Tag-Along Sale Notice") shall set forth: (i) the number of shares of Common
Stock and/or Preferred Stock subject to the proposed sale; (ii) the name and
address of the proposed purchaser; and (iii) the proposed amount and form of
consideration and terms and conditions of payment offered by such proposed
purchaser. Penhall shall promptly, and in any event within ten days, mail or
hand deliver or cause to be mailed or hand delivered the Tag-Along Sale Notice
to the Tag-Along Rightholders. Each Tag-Along Rightholder may exercise the
Tag-Along Right by delivery of a written notice (the "Tag-Along Acceptance
Notice") to the Tag-Along Seller and Penhall within thirty days of the date
Penhall mailed or caused to be mailed the Tag-Along Sale Notice. The Tag-Along
Acceptance Notice shall state the number of shares of Common Stock and/or
Preferred Stock that the Tag-Along Rightholder proposes to include in the
proposed sale. Penhall shall deliver notice (the "Unexercised Right Notice") to
all Stockholders, within ten (10) days following the thirty-day period specified
above, of any Tag-Along Rightholder not exercising his, her or its right to
include Securities in the proposed sale. All other Stockholders (including
without limitation the BRS Entities and the Tag-Along Seller) shall have the
opportunity to sell additional Securities in an aggregate amount equal to the
amount of Securities as to which any Tag-Along Rightholder shall not have
exercised a Tag- Along Right (the "Unexercised Securities"), on a pro rata basis
(based on the number of shares of Common Stock or Preferred Stock, as the case
may be, outstanding on a fully-diluted basis, but excluding from such
determination the Unexercised Securities). Any Stockholder exercising his, her
or its right to sell additional Securities in accordance with the foregoing
sentence must do so by delivering to the Tag-Along Seller a Tag- Along
Acceptance Notice within ten (10) days following delivery by Penhall of the
Unexercised Right Notice. If no Tag-Along Acceptance Notice is received during
the thirty-day period referred to above, the Tag-Along Seller shall have the
right for a 90-day period to effect the proposed sale of shares of Common Stock
and/or Preferred Stock on terms and conditions no more favorable than those
stated in the Tag-Along Sale Notice. Any Stockholder delivering a Tag-Along
Acceptance Notice shall participate in the proposed transaction as set forth in
Section 3.3(a). Concurrently with the consummation of the Significant Transfer,
the Tag-Along Seller shall (i) notify each Tag-Along Rightholder who has
delivered a Tag-Along Acceptance Notice (an "Accepting Tag-Along Holder"), (ii)
remit to the Accepting Tag-Along Holder the


                                       7



aggregate consideration for the shares of Common Stock and/or Preferred Stock to
be sold by the Accepting Tag-Along Holders in the Significant Transfer as
contemplated pursuant to Section 3.3(a) hereof, and (iii) furnish such other
evidence of the completion and time of completion of the Significant Transfer
and the terms thereof as may be reasonably requested by the Accepting Tag-Along
Holders.

              (c)    (i) Notwithstanding the other requirements of this Section
3.3, a Tag-Along Seller may sell Common Stock and/or Preferred Stock at any time
without complying with the requirements of Section 3.3(b) so long as the
Tag-Along Seller deposits into escrow with a nationally recognized financial
institution at the time of sale that amount of consideration received in the
sale equal to the "Escrow Amount." As used herein, the "Escrow Amount" shall
equal that amount of consideration that all Tag-Along Rightholders would have
been entitled to receive if they had the opportunity to participate in the sale
on a pro rata basis, determined as if each Tag-Along Rightholder (A) delivered a
Tag-Along Acceptance Notice to the Tag-Along Seller in the time period set forth
in Section 3.3(b) and (B) proposed to include all of her, his or its shares of
Common Stock and/or Preferred Stock in such sale.

                     (ii) The Tag-Along Seller shall notify Penhall in writing
of a sale pursuant to this Section 3.3(c) no later than the date of such sale.
Such notice (the "Escrow Notice") shall set forth the information required in
the Tag- Along Sale Notice, and in addition, such notice shall state the name of
the escrow agent and, if the consideration (in whole or in part) for the sale
was cash, then the account number of the escrow account. Penhall shall promptly,
and in any event within ten days, mail or cause to be mailed the Escrow Notice
to each Tag-Along Rightholder. Such Tag-Along Rightholder may exercise the
Tag-Along Right by delivery to the Tag-Along Seller and Penhall, within thirty
days of the date Penhall mailed or caused to be mailed the Escrow Notice, of (A)
a written notice specifying the number of shares of Common Stock and/or
Preferred Stock it proposes to sell and (B) the certificates for such Common
Stock and/or Preferred Stock, with stock powers duly endorsed in blank and with
signatures guaranteed. Penhall shall deliver an Unexercised Right Notice to all
Stockholders, within ten (10) days following the thirty-day period specified
above, of any Tag-Along Rightholder not exercising his, her or its right to
include Securities in the sale. All other Stockholders (including without
limitation the BRS Entities and the Tag-Along Seller) shall have the opportunity
to include additional Securities in the sale in an aggregate amount equal to the
amount of the Unexercised Securities, on a pro rata basis (based on the number
of shares of Common Stock or Preferred Stock, as the case may be, outstanding on
a fully-diluted basis, but excluding from such determination the Unexercised
Securities). Any Stockholder exercising his, her or its right to include
additional Securities


                                       8



in the sale in accordance with the foregoing sentence must do so by delivering
to the Tag-Along Seller, within ten (10) days following delivery by Penhall of
the Unexercised Right Notice, (A) a written notice specifying the additional
number of shares of Common Stock and/or Preferred Stock it proposes to sell and
(B) the certificates for such Common Stock and/or Preferred Stock, with stock
powers duly endorsed in blank and with signatures guaranteed.

                     (iii) Promptly after the expiration of the thirtieth day
after Penhall has mailed or caused to be mailed the Escrow Notice, or, promptly
after the expiration of the tenth day after Penhall has delivered the
Unexercised Right Notice, as the case may be, (A) the Tag-Along Seller shall
purchase that number of shares of Common Stock and/or Preferred Stock as the
Tag-Along Seller would have been required to include in the sale had the
Tag-Along Seller complied with the provisions of Section 3.3(b), (B) all shares
of Common Stock and/or Preferred Stock not required to be purchased by the
Tag-Along Seller shall be returned to the Tag-Along Rightholders thereof and (C)
all remaining funds and other consideration held in escrow shall be released to
the Tag-Along Seller. If the Tag-Along Seller received consideration other than
cash in his, her or its sale, the Tag-Along Seller shall purchase the shares of
Common Stock and/or Preferred Stock tendered by paying to the Tag-Along
Rightholders the same non-cash consideration and cash in the same proportion as
received by the Tag-Along Seller in the sale. The Tag-Along Seller shall pay all
costs and expenses of the escrow agent, and any interest on the Escrow Amount
shall accrue to the benefit of Penhall.

              (d) The Tag-Along Rights provided pursuant to this Section 3.3
shall terminate on the one hundred eightieth (180th) day following an Initial
Public Offering, or upon a distribution by BRS of all the Securities to its
partners. An "Initial Public Offering" shall mean the sale by Penhall in an
underwritten public offering made pursuant to an effective registration
statement under the Securities Act of Common Stock for gross offering proceeds
of at least $30 million.

              (e) Notwithstanding anything to the contrary, a Tag-Along Seller
may make any of the following sales without offering the Tag-Along Rightholders
the opportunity to participate: (a) sales pursuant to an effective registration
statement under the Securities Act; and (b) sales pursuant to an Approved Sale.

              (f) As used herein, "Affiliate" of any person means any person,
directly or indirectly, controlling, controlled by or under common control with
such person, and includes any person who is an officer, director or employee of
such person and any person who would be deemed to be an "affiliate" or an
"associate" of such person, as those terms are defined in Rule 12b-2 of the
General Rules and Regulations under the Securities Exchange Act of 1934, as
amended. As used in this definition, "controlling" (including,


                                       9



with its correlative meanings, "controlled by" and "under common control with")
means possession, directly or indirectly, of power to direct or cause the
direction of management or policies (whether through owner ship of securities,
partnership or other ownership interests, by contract or otherwise).

                                   ARTICLE IV

hereby approves and ratifies the same.

         4.2 Directors. (a) Each Stockholder and Permitted Transferee agrees
that it shall take, at any time and from time to time, all action necessary
(including voting the Common Stock owned by him, her or it, calling special
meetings of stockholders and executing and delivering written consents) to
ensure that the Board of Directors of Penhall is composed at all times of no
less than three and no more than seven persons (with the exact number to be
determined by BRS from time to time). If the Board of Directors is composed of
three or four persons, then one individual shall be designated by the Management
Stockholders holding a majority of the Common Stock owned by the Management
Stockholders (who shall be, subject to the rights of the Management Stockholders
under Section 4.3, John T. Sawyer for so long as he is President of Penhall) and
the remainder shall be designated by BRS. If the Board of Directors is composed
of five or more persons, then two individuals shall be designated by the
Management Stockholders holding a majority of the Common Stock owned by the
Management Stockholders (who shall be, subject to the rights of the Management
Stockholders under Section 4.3, Management Stockholders and officers of Penhall
during the term of their directorship) and the remainder shall be designated by
BRS.

              (b) Each Stockholder agrees to take all necessary action to cause
the Board of Directors of Penhall to be as set forth in Section 4.2(a)
(including, without limitation, voting or causing to be voted or acting by
written consent with respect to, all shares of Common Stock entitled to be voted
thereon now or hereafter owned or held by such Stockholder in favor of such
persons) and to act itself (if a member of the Board of Directors) or cause its
nominee (if any) on the Board of Directors to vote or act by written consent to
cause the Board of Directors of Penhall to be as set forth in Section 4.2(a).

              (c) Pursuant to the authority of Section 10-704 of the Arizona
Business Corporation Act, the Stockholders, being all


                                       10



of the shareholders of Penhall entitled to vote, do hereby dispense with the
formality of a meeting and approve and ratify the election of the following
persons as the directors of Penhall to hold office until the next annual meeting
of stockholders and until their respective successors shall have been elected
and qualified or until resignation, removal or death as provided in the Bylaws
of Penhall and this Agreement:

                           Harold O. Rosser II
                           Bruce C. Bruckmann
                           John T. Sawyer

         4.3 Right to Remove Certain of Penhall's Directors. Each of BRS and the
Management Stockholders holding a majority of the Common Stock owned by the
Management Stockholders, as the case may be, may request that any director
designated by it be removed (with or without cause) by written notice to the
other Stockholders, and, in any such event, each Stockholder shall promptly
consent in writing or vote or cause to be voted all shares of Common Stock now
or hereafter owned or controlled by it for the removal of such person as a
director. In the event any person ceases to be a director, such person shall
also cease to be a member of any committee of the Board of Directors of Penhall.

         4.4 Right to Fill Certain Vacancies in Penhall's Board. In the event
that a vacancy is created on Penhall's Board of Directors at any time by the
death, disability, retirement, resignation or removal (with or without cause) of
a director designated by BRS or the Management Stockholders holding a majority
of the Common Stock owned by the Management Stockholders, as the case may be, or
if otherwise there shall exist or occur any vacancy on Penhall's Board of
Directors in a directorship subject to designation by BRS or the Management
Stockholders holding a majority of the Common Stock owned by the Management
Stockholders, as the case may be, such vacancy shall not be filled by the
remaining members of Penhall's Board of Directors, but each Stockholder hereby
agrees promptly to consent in writing or vote or cause to be voted all shares of
Common Stock now or hereafter owned or controlled by it to elect that individual
designated to fill such vacancy and serve as a director, as shall be designated
by BRS or the Management Stockholders holding a majority of the Common Stock
owned by the Management Stockholders, as the case may be.

                  4.5 Subsidiaries Governance. Each Stockholder agrees that the
board of directors of each of the Companies shall be comprised of one individual
designated by BRS (so long as the BRS Entities continue to own at least 50% of
the Common Stock held by BRS Entities on the date hereof). Each Stockholder
agrees to vote all of its Securities and to cause its representatives on the
Board of Directors of Penhall, subject to their fiduciary duties, to vote and
take other appropriate action to effectuate the agreement set forth in this
Sections 4.5 in respect of each of the Companies.


                                       11



         4.6 Management Rights. For so long as BRS Entities own in the aggregate
at least 30% of the outstanding Common Stock on a fully diluted basis and there
has not been an Initial Public Offering:

              (a) Right of Consultation. BRS shall have the right, and Penhall
shall cause each of the Companies to grant to BRS the right, to consult with and
advise the management of Penhall and its subsidiaries, at any time or from time

subsidiaries, including, without limitation, significant changes in management
personnel and compensation or employee benefits, the introduction of new
products or new lines of business, important acquisitions or dispositions of
plant and equipment, significant research and development programs, the purchase
or sale of important patents, trademarks, licenses and concessions, and the
proposed compromise of any significant litigation.

              (b) Observation Rights. BRS shall have the right, and Penhall
shall cause each of the Companies to grant to BRS the right, to have its
representatives (in addition to its representatives that are directors) attend
meetings of the Board of Directors (and committees thereof) of Penhall and each
of the Companies. Penhall shall give, or shall cause each of the Companies to
give, as appropriate, to BRS (i) at least three days' notice of each regular
meeting of the Board of Directors of Penhall and each of the Companies, (ii)
such notice as is practicable under the circumstances to enable BRS's
representatives to attend each special or emergency meeting of the Board of
Directors of Penhall and each of the Companies, (iii) on or prior to the date of
each meeting of the Board of Directors of Penhall and each of the Companies all

              (c) Inspection and Access. In addition to the reporting

Entities true and correct copies of all quarterly and annual financial reports
of each of the Companies and budgets prepared by or on behalf of Penhall and of
each of the Companies, and such other documents, reports, financial data and
other information as BRS Entities may reasonably request. Penhall shall permit
any authorized representatives designated by BRS Entities to visit and inspect
any of the properties of Penhall or any of its subsidiaries, including its and
their books of account (and to make copies and take extracts therefrom), and to
discuss its and their affairs, finances and accounts with its and their officers
and their current and prior independent public accountants (and by this
provision Penhall authorizes such accountants to discuss with such
representatives the affairs, finances and accounts of Penhall and its
subsidiaries, whether or not a


                                       12



representative of Penhall is present), all at such reasonable times and as often
as BRS Entities may reasonably request.

              4.7 Confidentiality. (a) Each Stockholder hereby agrees that
Confidential Information (as defined below) has been and will be made available
to him or it in connection with such Stockholder's interest in Penhall and its
subsidiaries. Each Stockholder agrees that he or it will not use the
Confidential Information in any way that is reasonably likely to result in a
material detriment to the business of Penhall and its subsidiaries. Each
Stockholder further acknowledges and agrees that he or it will not disclose any
Confidential Information to any person; provided that Confidential Information
may be disclosed (i) to such Stockholder's Representatives (as defined below) in
the normal course of the performance of their duties, (ii) to the extent
required by applicable statute, law, rule or regulation (including complying

documents, subpoena, civil investigative demand or similar process to which an
Stockholder is subject) or by GAAP, (iii) to any third party to whom such
Stockholder is contemplating a transfer of his or its Securities, provided that
such transfer would not be in violation of the provisions of this Agreement and
as long as such third party is advised of the confidential nature of such
information and agrees to be bound by a confidentiality agreement in form and
substance reasonably satisfactory to Penhall and substantially similar to the
provisions hereof or (iv) if the prior consent of the Board of Directors of
Penhall shall have been obtained. Nothing contained herein shall prevent the use
of Confidential Information in connection with the assertion or defense of any
claim by or against Penhall or any Stockholder.

              (b) "Confidential Information" means any information concerning
Penhall, its financial condition, business, subsidiaries, operations or
prospects in the possession of or to be furnished to any Stockholder or
Stockholder representative in his or its capacity as a shareholder of Penhall or
Stockholder representative or pursuant to this Agreement or by virtue of his or
its present or former position as, or right to designate, a director of Penhall;
provided that the term "Confidential Information" does not include information
which (a) was or becomes generally available publicly other than as a result of
a disclosure by an Stockholder or his or its partners, directors, officers,
employees, agents, counsel, investment advisers, consultants or representatives
(all such persons being collectively referred to as "Representatives") in
violation of this Section 4.7 or (b) was or becomes available to such
Stockholder on a nonconfidential basis from a source other than Penhall, any
regulatory entity or a Stockholder or his or its Representatives, provided that

to the best of such Stockholder's knowledge,


                                       13



bound by a confidentiality agreement with Penhall or another person.

anniversary of the date hereof and (y) the one hundred eightieth (180th) day

Stockholder nor


                                       28



his Permitted Transferees shall effect a Transfer of any Securities other than
(i) pursuant to Section 3.2 in connection with an Approved Sale, (ii) pursuant
to Section 3.3 in connection with the exercise of Tag-Along Rights, (iii)

(iv) pursuant to the Registration Rights Agreement under Article VI, (v) with
the consent of Penhall (as evidenced by a resolution duly adopted by at least a
majority of the non-employee members of Penhall's Board of Directors) or (vi) to
a Permitted Transferee of the Transferor Stockholder in question. Following the
Option Period, each Management Stockholder and his Permitted Transferees agree
that none of them will effect a Transfer of any Securities without first
complying with the provisions of Section 5.4 hereof, if then in effect.

         In exercising the consent and approval provided for in clause (iv)
above, Penhall may employ its sole discretion in evaluating the nature of the
proposed transferee and Penhall may impose such conditions on Transfer as it
deems appropriate in its sole discretion, including, but not limited to,
requirements that the transferee be an employee of Penhall or its subsidiaries
and that the transferee purchase the Management Stockholder's (or his Permitted
Transferee's) Securities as a "Management Stockholder" subject to the
restrictions of this Agreement and, in particular, this Article V. In the event
any Transfer is authorized pursuant to clause (iv) above or proposed to be made
to a Permitted Transferee (other than Penhall or a BRS Entity) under clause (v)
above, each such transferee shall take such Securities subject to and be fully
bound by the terms of this Agreement with the same effect as if it were a party
hereto and, without limiting the foregoing, such Transfer shall not be made or
effective unless the purported transferee executes an agreement, in form and
substance satisfactory to Penhall, pursuant to which such transferee shall agree
to be bound as a "Management Stockholder" by the terms and conditions of this
Agreement and such other provisions as Penhall may determine. Any purported
Transfer in violation of this Section 5.2 shall be null and void and of no force
and effect and the purported transferee shall have no rights or privileges in or
with respect to Penhall. Notwithstanding the foregoing provisions, each
Management Stockholder agrees that he or it will not effect a Transfer of any
Securities except in compliance with the registration requirements of the
Securities Act (and applicable state securities laws) or pursuant to an
available exemption therefrom, and, without limiting the foregoing, will not
effect a Transfer of any Securities prior to the lapse of such period of time
following acquisition thereof as may be required to comply with applicable state
securities laws.

                           (b)  Prior to any proposed Transfer of any
Securities pursuant to clauses (iv) and (v) of subparagraph (a) above, the
holder thereof shall give written notice to Penhall describing the manner and
circumstances of the proposed Transfer


                                       29



accompanied, if requested by Penhall, by a written opinion of legal counsel
reasonably satisfactory to Penhall, addressed to Penhall and the transfer agent,
if other than Penhall, and reasonably satisfactory in form and substance to each
addressee, to the effect that the proposed Transfer of the Securities may be
effected without registration under the Securities Act and applicable state
securities laws. Each certificate evidencing the Securities transferred shall
bear the legend set forth in Section 2.2, except that such certificate shall not
bear such legend if the opinion of counsel referred to above is to the further
effect that such legend is not required in order to establish compliance with
any provision of the Securities Act or applicable state securities laws.

                           (c)  A notation will be made in the appropriate
transfer records of Penhall with respect to the restrictions on Transfer of the
Securities referred to in this Agreement.

                           (a)  General Terms.  In the event that on or prior

Management Stockholder shall cease to be employed by Penhall or any of the
Companies for any reason (including, but not limited to, death, temporary or
permanent disability, retirement, resignation or termination by Penhall or such
Company with or without Cause), other than by reason of a leave of absence
approved by Penhall or such Company, such Management Stockholder or such
Management Stockholder's Permitted Transferees (or, in the case of death, his or
their estate) shall give prompt notice to Penhall of such termination of
employment, and:

                                    (i)  Penhall, or one or more designee(s)
selected by a majority of the members of the Board of Directors of Penhall,
shall have the right and option (the "Purchase Option"), at any time within 120
days from the later of the effective date of such termination of employment (the
"Termination Date") and the date of Penhall's receipt of aforesaid notice, to
purchase from such Management Stockholder, or such Management Stockholder's
Permitted Transferees, as the case may be, any or all of the Option Securities
then owned by such Management Stockholder and such Management Stockholder's
Permitted Transferees at the Option Purchase Price (as hereinafter defined); and

                                    (ii) such Management Stockholder shall have
the right and option (the "Put Option" and, together with the Purchase Option,
the "Options") to require Penhall, at any time within 120 days after the
Termination Date, to purchase from such Management Stockholder any or all of the
Option Securities then owned by such Management Stockholder at the Option
Purchase Price. Penhall or its designee(s) shall give notice to the terminated
Management Stockholder (or such Management Stockholder's Permitted


                                       30



Transferees) of its intention to exercise the Purchase Option not later than
within 120 days after the later of the Termination Date or the date of Penhall's
receipt of the aforesaid notice. The Termination Date for a Permitted Transferee
shall be the Termination Date with respect to the Management Stockholder who
first acquired the Option Securities held by such Permitted Transferee. A
terminated Management Stockholder shall give notice to Penhall of his intention
to exercise the Put Option not later than within 120 days after the Termination
Date.

                           (b)  Exercise of Options.  The Options shall be
exercised, in the case of the Purchase Option, by written notice to the
terminated Management Stockholder and Permitted Transferees signed by an officer
of Penhall on behalf of Penhall or by its designee(s), as the case may be, and,
in the case of the Put Option, by written notice to Penhall signed by the
terminated Management Stockholder or Permitted Transferees, prior to the end of
the 120-day period. Such notice shall set forth the number of shares of Option
Securities desired to be purchased or sold and shall set forth a time and place
of closing which shall be no earlier than 10 days and no later than 60 days
after the date such notice is sent. At such closing, the seller shall deliver
the certificates evidencing the number of shares of Option Securities to be
purchased by or sold to Penhall and/or its designee(s), accompanied by stock
powers duly endorsed in blank or duly executed instruments of transfer, and any
other documents that are necessary to transfer to Penhall and/or its designee(s)
good title to the Option Securities to be transferred, free and clear of all
pledges, security interests, liens, charges, encumbrances, equities, claims and
options of whatever nature other than those imposed under this Agreement, and
concurrently with such delivery, Penhall and/or its designee(s) shall deliver to
the seller the full amount of the Option Purchase Price for such Option
Securities.

                           (c)  Option Purchase Price.  If the Management
Stockholder shall cease to be employed by Penhall or any of the Companies by
reason of termination without Cause, the "Option Purchase Price" for the Common
Stock and/or Series B Preferred Stock to be purchased from such Management
Stockholder or such Management Stockholder's Permitted Transferees pursuant to
the Options (such number of shares of Common Stock and/or such number of shares
of Series B Preferred Stock, each being referred to as the "Purchase Number")
shall equal the price calculated as set forth in the table below opposite the
applicable Termination Date of such Management Stockholder:

                                       32



Management Investor), the Option Purchase Price for all shares of Common Stock

(and such Management Stockholder's Permitted Transferees) pursuant to the
Options shall equal the Original Cost multiplied by the Purchase Number.

                  Notwithstanding anything to the contrary contained herein, if

Management Investor following a Termination Date (a) in cash if the aggregate
amount owed as the result of the exercise of the Options is less than $500,000
or (b) if such amount is $500,000 or more, in cash or, at Penhall's option, by
means of a promissory note substantially in the form attached as Exhibit D
hereto; provided, however, that Penhall shall have the option to make such
payment by means of a promissory note regardless of the aggregate amount owed if
the Purchase Option or the Put Option has been exercised with respect to a
Management Stockholder who has voluntarily terminated his employment or has been
terminated for Cause.

                           (d)  Notwithstanding the foregoing, Penhall shall
not be obligated to purchase shares to the extent that (a) such purchase would
be illegal under applicable law, or (b) such purchase would result in a default
or an event of default (with or without the giving of notice, the passage of
time or both) under the terms of any indebtedness for borrowed money, it being
understood that Penhall will act in good faith to obtain waivers of any such
provisions.

                           (e)  The Options will lapse upon the earliest to
occur of (i) the expiration of the Option Period with respect to all Securities
held by Management Stockholders, (ii) the 180th day following an Initial Public
Offering and (iii) a transfer of

Securities by BRS as to which Tag-Along Rights apply, but only with respect to
Securities sold pursuant to such Tag-Along Rights.

                  5.4 Right of First Refusal on Transfer of Management
Stockholder Securities.

                           (a)  Right of First Refusal.  In the event that
any time after the expiration of the Option Period, a Management Stockholder (or
his Permitted Transferees) receives a bona fide offer (a "Transfer Offer") to
purchase any or all of the Securities (the "Transfer Securities") then owned by
the Management Stockholder (or his Permitted Transferees) from any person (the
"Offeror") which the Management Stockholder (or his Permitted Transferees)
wishes to accept, then the Management Stockholder (and his Permitted
Transferees) shall give Penhall and the other Stockholders written notice
thereof ("Transfer Notice"), which Transfer Notice shall state in reasonable
detail all material terms of such proposed sale or other transfer, the identity
of the Offeror, the price or other consideration for which the Securities are
proposed to be sold or transferred, and the number of Securities to be sold or
transferred, and shall also contain an irrevocable offer to sell the Transfer
Securities to Penhall at the price and on the terms contained in the Transfer
Offer. After its receipt of the Transfer Notice, Penhall and/or its designee(s)
shall have the right and option to purchase all, but not less than all (unless
other Stockholders purchase the remainder), of the Transfer Securities at the
price and on the terms of the Transfer Offer set forth in the Transfer Notice.
Within 30 days after receipt of the Transfer Notice, Penhall and/or its
designee(s) shall notify such Management Stockholder (or his Permitted
Transferees) whether or not it wishes to purchase the Transfer Securities and,
if so, indicating the number of Transfer Securities desired to be purchased.

                                    In the event that Penhall and/or its
designee(s) does not elect to purchase all such Transfer Securities, the selling
Management Stockholder (or his Permitted Transferees) shall give notice of such
failure to the other Stockholders, and the other Stockholders shall thereupon
have the right and option to purchase in the aggregate all, but not less than
all, the Transfer Securities not to be purchased by Penhall and/or its
designee(s) and may give notice to the selling Management Stockholder (or his
Permitted Transferees) (with a copy to Penhall) of such intention at any time
not later than 30 days after the date on which such notice is sent by the
selling Management Stockholder (or his Permitted Transferees) to such other
Stockholders. Each electing Stockholder's notice shall indicate the number of
Transfer Securities it desires to purchase. If the other Stockholders elect to
purchase an aggregate number of Transfer Securities in excess of the number of
Transfer Securities which Penhall and/or its designee(s) did not elect to
purchase, the Transfer Securities shall be allocated among the other
Stockholders


                                       34



who desire to purchase such Transfer Securities in accordance with the
allocation provisions which are set forth in Section 5.3(a)(i). Promptly upon
determining the number of the selling Management Stockholder's Securities which
each purchasing Stockholder will purchase and the purchase price therefor,
Penhall shall send notices thereof to the selling Management Stockholder and
each of the purchasing Stockholders.

                           (b)  Exercise and Nonexercise of Right of First
Refusal. Exercise of the option provided for in Section 5.4(a) shall be effected
by the giving of written notice to the Management Stockholder (and his Permitted
Transferees) by Penhall (on its own behalf and/or on behalf of its designee(s),
as the case may be), signed by an officer of Penhall, and, if applicable, the
other Stockholders, prior to the end of the period during which the option is
exercisable (and such notice shall be effective when given). If Penhall and/or
its designee(s) and the other Stockholders in the aggregate elect to purchase
all of the Transfer Securities, the closing of the purchase and sale of the
Transfer Securities pursuant to any such option exercise shall be held at such
place and such date to be established by Penhall in the later of its notice to
the selling Management Stockholder in response to the Transfer Notice and its
notice to the other Stockholders of the allocation of the number of Transfer
Securities which such Stockholders are to purchase, which in no event shall be
earlier than 10 days or later than 60 days from the date of such notice.

                   In the event Penhall and/or its designee(s) and the other
Stockholders fail to exercise the purchase option provided for in Section
5.4(a), then, subject to the other provisions of this Agreement, for a period of
45 days, the Transfer Securities may be sold or transferred by or an behalf of
the Management Stockholder (or his Permitted Transferees) to the Offeror
specified in the Transfer Notice at a price not less than the price per
Securities specified therein and otherwise on terms no less favorable to the
Management Stockholder and no more favorable to the Offeror than those contained
in the Transfer Notice.

                           (c)  The options provided for in Section 5.4(a)
will lapse upon the one hundred eightieth (180th) day following an Initial
Public Offering.

                  5.5 Purchaser Representative. If Penhall or any Stockholder
enters into any negotiation or transaction for which Rule 506 (or any similar
rule then in effect) promulgated by the Securities and Exchange Commission under
the Securities Act may be available with respect to such negotiation or
transaction (including a merger, consolidation or other reorganization), each
Stockholder will, at the request of Penhall, appoint a purchaser representative
(as such term is defined in Rule 501(h) promulgated by the Securities and
Exchange Commission under the Securities Act)


                                       35



reasonably acceptable to Penhall. If any Stockholder appoints the purchaser
representative designated by Penhall, Penhall will pay the fees of such
purchaser representative, but if any Stockholder declines to appoint the
purchaser representative designated by Penhall, such Stockholder will appoint,
at his own expense, another purchaser representative (reasonably acceptable to
Penhall).

                  5.6  Involuntary Transfers.
                       ---------------------

                           (a)  Option to Purchase.  In the event that the
Securities owned by a Management Stockholder (or his Permitted Transferees)
shall be subject to sale or other transfer by reason of any of the following
events (a "Nonvolitional Event"): (i) bankruptcy or insolvency proceedings,
whether voluntary or involuntary, or (ii) a divorce (whether in connection with
a settlement of the divorce or entry of a decree or judgment of divorce), or
(iii) distraint, levy, execution or other involuntary transfer, then the
Management Stockholder (and his Permitted Transferees) shall give Penhall
written notice thereof ("Involuntary Transfer Notice") promptly upon the
occurrence of such Nonvolitional Event, which Involuntary Transfer Notice shall
state the terms of such proposed sale or other transfer, the identity of the
proposed purchaser or other transferee, the price or other consideration, if
readily determinable, for which the Securities are proposed to be sold or
transferred, and the number of Securities to be sold or transferred (the
"Involuntarily Transferred Securities"). After its receipt of the Involuntary
Transfer Notice or, failing such receipt, after Penhall otherwise obtains actual
knowledge of such a proposed sale or other transfer, Penhall and/or its
designee(s) shall have the right and option to purchase all, but not less than
all, of the Involuntarily Transferred Securities, such option to be exercisable
at any time within 120 days after receipt of the Involuntary Transfer Notice or,
failing such receipt, after Penhall otherwise obtains actual knowledge of such a
proposed sale or other transfer.

                                    In the event that Penhall and/or its
designee(s) does not elect to purchase all such Involuntarily Transferred
Securities, the Management Stockholder (or his Permitted Transferees) shall give
notice of such failure to the other Stockholders, and the other Stockholders
shall thereupon have the right and option to purchase in the aggregate all, but
not less than all, the Involuntarily Transferred Securities not to be purchased
by Penhall and/or its designee(s) and may give notice to the Management
Stockholder (or his Permitted Transferees) (with a copy to Penhall) of such
intention at any time not later than 45 days after the date on which such notice
is sent by the selling Management Stockholder (or his Permitted Transferees) to
such other Stockholders. Each electing Stockholder shall indicate the number of
Involuntarily Transferred Securities it desires to purchase.


                                       36



                   If the other Stockholders elect to purchase an aggregate
number of Involuntarily Transferred Securities in excess of the number of
Involuntarily Transferred Securities which Penhall and/or its designee(s) did
not elect to purchase, the Involuntarily Transferred Securities shall be
allocated among the other Stockholders who desire to purchase such Involuntarily
Transferred Securities in proportion to the number of Involuntarily Transferred
Securities (on a fully diluted basis) owned by each of them; provided that no
such other Stockholder shall become bound to purchase a number of offered
Involuntarily Transferred Securities greater than the number of shares of
Involuntarily Transferred Securities it or he had elected to purchase. If the
foregoing allocation procedure does not allocate all the Involuntarily
Transferred Securities (because one or more Stockholders would otherwise have
been allocated more than the number of shares of Involuntarily Transferred
Securities it or he elected to purchase), then the remaining such shares of
Involuntarily Transferred Securities shall be allocated among the other
Stockholders who desire to purchase such Involuntarily Transferred Securities in
proportion to the number of shares of Involuntarily Transferred Securities (on a
fully diluted basis) owned by each of them, and such allocation procedure shall
continue until all such Involuntarily Transferred Securities shall have been
allocated. Promptly upon determining the number of the Involuntarily Transferred
Securities which each purchasing Stockholder will purchase and the purchase
price thereof, Penhall shall send notices thereof to the Management Stockholder
and each of the purchasing Stockholders.

                           (b)  Purchase Price.  Any purchase pursuant to the
foregoing option contained in Section 5.6(a) shall be at the lowest of (i) the
price applicable to such proposed sale or transfer, (ii) if during the Option
Period, at the applicable Option Purchase Price set forth under Section 5.2(c)
multiplied by the number of Involuntarily Transferred Securities if such
Management Stockholder shall be employed by Penhall or any of the Companies at
the time of such Involuntary Transfer or shall not be employed by Penhall or any
of the Companies by reason of termination without Cause, death or disability and
(iii) if during the Option Period, at Original Cost multiplied by the number of
Involuntarily Transferred Securities if such Management Stockholder shall not be
employed by Penhall or any or the Companies at the time of such Involuntary
Transfer by any reason other than termination without Cause, death or
disability.

                           (c)  Exercise and Nonexercise of Option.  Exercise
of the option provided for in Section 5.6(a) shall be effected by the giving of
written notice to the Management Stockholder (and his Permitted Transferees) and
the proposed purchaser or transferee by Penhall (on its own behalf and/or on
behalf of its designee(s), as the case may be), signed by an officer of Penhall,
and, if applicable, by the purchasing Stockholders prior to the end of the


                                       37



period during which the option is exercisable (and such notice shall be
effective when given). The closing of the purchase and sale of the Involuntarily
Transferred Securities pursuant to any such option exercise shall be held at
such place and such date to be established by Penhall, which in no event shall
be less than 10 or more than 60 days from the date of such notice.

                   In the event Penhall and/or its designee(s) or the other
Stockholders fail to exercise the purchase option provided for in Section
5.6(a), then the Involuntarily Transferred Securities may be sold or transferred
by or on behalf of the Management Stockholder (and his Permitted Transferees) on
the terms contained in the Involuntary Transfer Notice, but the transferee or
purchaser shall be subject to all of the obligations contained in this Agreement
which were applicable to the Management Stockholder in respect of the
Involuntarily Transferred Securities and, without limiting the generality of the
foregoing, if the Management Stockholder incurs a Termination Date on or prior
to the expiration of the Option Period, the Purchase Option contained in Section
5.3 hereof shall apply to the Involuntarily Transferred Securities at the
applicable Option Purchase Price.

                  5.7 Covenant Not to Compete. Each Management Stockholder
hereby agrees that during the term of his employment by Penhall or any of the
Companies and for the period specified opposite such Management Stockholder's
name on Exhibit E hereto after the Management Stockholder has incurred a
Termination Date for any reason other than termination without Cause, such
Management Stockholder shall not, 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 on the date
hereof by Penhall or any of the Companies (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 Penhall or any of the Companies at any time
during the twelve (12) months preceding the date of this Agreement.
Notwithstanding the foregoing, the provisions of this Section 5.7 shall not
apply to any Management Stockholder incurring a Termination Date in the event
that Penhall fails to purchase the Securities of such Management Stockholder
when obligated to purchase such Securities under Section 5.3 after the exercise
by such Management Stockholder of the Put Option. 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,


                                       38



Virginia, Washington, West Virginia, Wisconsin, Wyoming, and all other counties
of other states of the United States or foreign jurisdictions in which Penhall
or any of the Companies has conducted business, or during the period applicable
to any Management Stockholder, shall have conducted business. None of the
foregoing shall prevent any Management Stockholder from owning up to 5% of the
outstanding equity of a publicly-traded company or from making indirect
investments through an investment partnership or other investment entity in any
corporation, partnership, limited liability company or other person or entity.

                  The parties agree that to the extent any provision or portion
of this Section 5.7 shall be held, found or deemed to be unreasonable, unlawful
or unenforceable by a court of competent jurisdiction, then any such provision
or portion shall be deemed to be modified to the extent necessary in order that
any such provision or portion 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 in order that any such provision or portion shall
be enforced to the fullest extent permitted by applicable law.

                  As the violation by a Management Stockholder of the provisions
of this Section 5.7 would cause irreparable injury to Penhall and the Companies,
and there is no adequate remedy at law for such violation, Penhall 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
Management Stockholder in a court of equity from violating such provisions. Each
Management Stockholder hereby waives any and all defenses he or she 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
Penhall may have. The prevailing party in any enforcement action or court
proceeding under this Section 5.7 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.

                  5.8 Obligations of J&J Investments, LLC and Michael Bruce
Repchinuck Revocable Trust. Notwithstanding anything to the contrary contained
herein, the obligations of J&J Investments, LLC and Michael Bruce Repchinuck
Revocable Trust under this Agreement shall be the obligations of John T. Sawyer
and M. Bruce Repchinuck (including, without limitation, under Article V),
respectively, and such obligations (including, without limitation, under Article
V) shall be determined with reference to the employment of John T. Sawyer and M.
Bruce Repchinuck, respectively.

                  7.1 Amendment and Modification. This Agreement may be amended
or modified, or any provision hereof may be waived, provided that such
amendment, modification or waiver is set forth in a writing executed by (i)
Penhall, (ii) BRS (so long as BRS Entities and its Permitted Transferees own in
the aggregate at least 5% of the outstanding Common Stock on a fully diluted
basis) and (iii) the holders of a majority of the outstanding Common Stock on a
fully diluted basis (including Common Stock owned by the BRS Entities) held by
the Stockholders; provided, however, that, without the approval of the holders
of a majority of the outstanding Common Stock then held by the Management
Stockholders, (x) the provisions of this Agreement cannot be amended to treat
the Management Stockholders differently than the other Stockholders and (y) the
provisions of this Agreement may not be amended or modified to the detriment of
the Management Stockholders. No course of dealing between or among any persons
having any interest in this Agreement will be deemed effective to modify, amend
or discharge any part of this Agreement or any rights or obligations of any
person under or by reason of this Agreement.

                  7.2 Survival of Representations and Warranties. The
representations and warranties set forth in Section 2.1 of this Agreement will
survive the execution and delivery of this Agreement, regardless of any
investigation made by an Stockholder or on its behalf. No other representations,
warranties or covenants set forth herein shall so survive.

                  7.3 Successors and Assigns; Entire Agreement.  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 and executors, administrators and heirs; provided, however, that except
as set forth in this Agreement, no party may assign, delegate or otherwise
transfer any


                                       40



of its rights or obligations under this Agreement. This Agreement sets forth the
entire agreement and understanding among the parties as to the subject matter
hereof and merges and supersedes all prior discussions, agreements and
understandings of any and every nature among them.

                  7.4 Separability. In the event that any provision of this
Agreement or the application of any provision hereof is declared to be illegal,
invalid or otherwise unenforceable by a court of competent jurisdiction, the
remainder of this Agreement shall not be affected except to the extent necessary
to delete such illegal, invalid or unenforceable provision unless that provision
held invalid shall substantially impair the benefits of the remaining portions
of this Agreement.

                  7.5 Notices. All notices provided for or permitted hereunder
