              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                               DECEMBER 31, 1998
                                  (UNAUDITED)


(1) BASIS OF PRESENTATION

      Penhall International, Inc. ("PII") was founded in 1957 and was
incorporated in the state of California on April 19, 1988. On August 4, 1998,
$100,000,000 of 12% Senior Notes (the Senior Notes) were sold by Penhall
Acquisition Corp., an Arizona corporation formed by an unrelated third party
(the Third Party) to effect the recapitalization of PII. As part of the
recapitalization, a series of mergers (the Recapitalization Mergers) were
consummated pursuant to which Phoenix Concrete Cutting, Inc., a wholly-owned
subsidiary of PII, became the corporate parent of PII, the Third Party acquired
a 62.5% interest in Phoenix Concrete Cutting, Inc. and Phoenix Concrete Cutting,
Inc. became the successor obligor of the Senior Notes. Following the
consummation of the Recapitalization Mergers, Phoenix Concrete Cutting, Inc.
changed its name to Penhall International Corp., and PII changed its name to
Penhall Rental Corp.

      Under generally accepted accounting principles, the Recapitalization 
Mergers were accounted for as a leveraged recapitalization transaction in a 
manner similar to a pooling-of-interests. Under this method, the transfer of 
controlling interest in PII to a new investor did not change the accounting 
basis of the assets and liabilities in PII's separate stand-alone financial 
statements.

      On October 1, 1998 all of the operating assets and liabilities of Penhall 
International Corp. were transferred to Penhall Company. As a result, all of 
the operating divisions of the Company are owned by Penhall Company.

      The accompanying unaudited condensed consolidated financial statements of
Penhall International Corp. ("Penhall" or the "Company") have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with the instructions to form 10-Q and Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting of normal
recurring accruals) considered necessary for a fair presentation have been
included.

      Results of operations for the three and six month periods ended December
31, 1998 are not necessarily indicative of the results that may be expected for
the year ending June 30, 1999. The unaudited condensed consolidated financial
statements included herein should be read in conjunction with the Company's
audited consolidated financial statements and footnotes thereto included in the
Registration statement on Form S-4 as of and for the year ended June 30, 1998.

      EARNINGS (LOSS) PER SHARE

      Basic earnings (loss) per share is computed by dividing adjusted net
earnings (loss) available to common stockholders by the weighted average number
of common shares outstanding during the period. The Company has granted certain
options which have been treated as potentially dilutive common shares for
purposes of calculating diluted earnings (loss) per share. Dilutive earnings
(loss) per share reflects the potential dilution that could share in the
earnings of the Company. Such shares are not included when there is a loss as
the effect would be anti-dilutive. 

      All common shares included in the condensed consolidated financial
statements and earnings (loss) per share calculations have been restated to
reflect a 10.56 to one common stock split effected as part of the
Recapitalization Mergers.

      The following table sets forth the calculation of diluted earnings (loss)
per share for the three and six-month periods ended December 31, 1998 and 1997:

(3) REDEEMABLE PREFERRED STOCK

SENIOR EXCHANGEABLE PREFERRED STOCK

      As of August 4, 1998 and in connection with the Recapitalization Mergers,
Penhall International Corp. is authorized to issue up to 250,000 shares of
preferred stock, par value $.01 per share ("Preferred Stock"), of which 10,000
shares have been designated as Senior Exchangeable Preferred Stock. With respect
to dividend rights and rights on liquidation, winding up and dissolution of
Penhall International Corp., the Senior Exchangeable Preferred Stock ranks
senior to the Common Stock, the Series A Preferred Stock and the Series B
Preferred Stock. Holders of Senior Exchangeable Preferred Stock are entitled to
receive, when as and if declared by the Board of Directors of Penhall
International Corp., out of funds legally available for payment thereof, cash
dividends on each share of Senior Exchangeable Preferred Stock at a rate per
annum equal to 10.5% of the Senior Exchangeable Preferred Liquidation Preference
(as defined below) of such share before any dividends are declared and paid, or
set apart for payment, on any shares of capital stock junior to the Senior
Exchangeable Preferred Stock ("Senior Exchangeable Junior Stock") with respect
to the same dividend period. All dividends shall be cumulative without interest,
whether or not earned or declared. "Senior Exchangeable Preferred Liquidation
Preference" means, on any specific date, with respect to each share of Senior
Exchangeable Preferred Stock, the sum of (i) $1,000 per share plus (ii) the
accumulated unpaid dividends with respect to such share.

      Penhall International Corp. may, at its option, redeem at any time, from
any source of funds legally available therefor, in whole or in part, any or all
of the shares of senior exchangeable preferred stock, at a redemption price per
share equal to 100% of the then effective senior exchangeable preferred
liquidation preference per share, plus an amount equal to a prorated dividend
for the period from the dividend payment date immediately prior to the
redemption date to the redemption date. On February 1, 2007, Penhall
International Corp. shall redeem, from any source of funds legally available
therefor, all of the then outstanding shares of senior exchangeable preferred
stock at a redemption price per share equal to 100% of the then effective senior
exchangeable preferred liquidation preference per share, plus an amount equal to
a prorated dividend for the period from the dividend payment date immediately
prior to the redemption date to the redemption date.

      The senior exchangeable preferred stock is exchangeable by Penhall
International Corp. at any time and from time to time for junior subordinated
notes (the "junior subordinated notes") in an amount equal to the senior
exchangeable preferred liquidation preference plus an amount equal to a prorated
dividend for the period from the dividend payment date immediately prior to the
exchange date to the exchange date. The junior subordinated notes will pay
interest from the date of exchange at the rate of 10.5% per annum in cash;
provided, however, that Penhall International Corp. shall be prohibited from
paying interest on the junior subordinated notes in cash for so long as the
notes shall remain outstanding. In such event, interest shall be deemed to be
paid by such amount being added to the outstanding principal amount of the
junior subordinated notes and shall accrue interest as a portion of the
principal amount of the junior subordinated notes to the maximum extent
permitted by law. If issued, the junior subordinated notes will mature on
February 1, 2007.

      In the event of a voluntary or involuntary liquidation, dissolution or
winding up of Penhall International Corp., holders of senior exchangeable
preferred stock shall be entitled to be paid out of the assets of Penhall
International Corp. available for distribution to its stockholders an amount in
cash equal to the senior exchangeable preferred liquidation preference per
share, plus an amount equal to a prorated dividend from the last dividend
payment date to the date fixed for liquidation, dissolution or winding up,
before any distribution is made on any shares of senior exchangeable junior
stock. If such available assets are insufficient to pay the holders of the
outstanding shares of senior exchangeable preferred stock in full, such assets,
or the proceeds thereof, shall be distributed ratably among such holders. Except
as otherwise required by law, the holders of senior exchangeable preferred stock
have no voting rights and are not be entitled to any notice of meeting of
stockholders.

      SERIES A PREFERRED STOCK

      Penhall International Corp. has designated 25,000 shares of Preferred
Stock as Series A Preferred Stock. With respect to dividend rights and rights on
liquidation, winding up and dissolution of Penhall International Corp., the
Series A Preferred Stock ranks senior to the Common Stock and on a parity with
the Series B Preferred Stock. Holders of Series A Preferred Stock are entitled
to receive, when, as and if declared by the Board of Directors of Penhall
International Corp., out of funds legally available for payment thereof, cash
dividends on each share of Series A Preferred Stock at a rate per annum equal to
13% of the Liquidation Preference (as defined below) of such share before any
dividends are declared and paid, or set apart for payment, on any shares of
capital stock junior to the Series A Preferred Stock ("Junior Stock") with
respect to the same dividend period. All dividends shall be cumulative without
interest, whether or not earned or declared. "Liquidation Preference" means, on
any specific date, with respect to each share of Series A Preferred Stock, the
sum of (i) $1,000 per share plus (ii) the accumulated dividends with respect to
such share.

      Penhall International Corp. may, at its option, redeem at any time, from
any source of funds legally available therefor, in whole or in part, any or all
of the shares of Series A Preferred Stock, at a redemption price per share equal
to 100% of the then effective Liquidation Preference per share, plus an amount
equal to a prorated dividend for the period from the dividend payment date

Liquidation Preference per share, plus an amount equal to a prorated dividend
from the last dividend payment date to the date fixed for liquidation,
dissolution or winding up, before any distribution is made on any shares of
Junior Stock. If such available assets are insufficient to pay the holders of
the outstanding shares of Series A Preferred Stock in full, such assets, or the
proceeds thereof, shall be distributed ratably among such holders. Except as
otherwise required by law, the holders of Series A Preferred Stock have no
voting rights and are not be entitled to any notice of meeting of stockholders.

(4) COMMITMENTS AND CONTINGENCIES

LITIGATION

      There are various lawsuits and claims pending against and claims being
pursued by the Company and its subsidiaries arising out of the normal course of
business. It is management's present opinion that the outcome of these
proceedings will not have a material effect on the Company's consolidated
financial statements taken as a whole.

(5) ACQUISITIONS

      On April 29, 1998, Penhall Company, a wholly owned subsidiary of the
Company, purchased substantially all of the assets of Highway Services, Inc. for
approximately $9,654,000 plus the assumption of approximately $1,324,000 of
liabilities. Penhall Company paid approximately $5,962,000 in cash, with the
remainder payable in equal installments in April 1999 and 2000 pursuant to a
$3,692,000 secured promissory note, which bears interest at 5.51% per annum. HSI
is based in Minnesota and operates in approximately 25 states and is a national
provider of construction services including grinding, grooving, sawing, sealing
and pavement replacement. The acquisition has been accounted for by the purchase
method and accordingly, the results of operations of HSI have been included in
the Company's consolidated financial statements since April 29, 1998. The excess
of the purchase price over the fair value of the net identifiable assets
acquired of approximately $8,291,000 has been recorded as goodwill and is being
amortized on a straight-line basis over 15 years. The purchase agreement also 
provides that certain stockholders of HSI purchase 3,147 shares of the 
Company's common stock for $1,000,000.

      The following unaudited pro forma financial information presents the
combined results of operations of the Company and HSI for the six months ended
December 31, 1997, as if the acquisition had occurred as of the beginning of
that period, after giving affect to certain adjustments, including amortization
of goodwill and increased interest expense on debt related to the acquisition.
The pro forma financial information does not necessarily reflect the results of
operations that would have occurred had the Company and HSI constituted a single
entity during such period.

      On October 16, 1998, the Company purchased certain assets of Daley
Concrete Cutting, a division of U. S. Rentals, for $3,743,000 in cash. Daley
Concrete Cutting has four offices, three located in South Carolina and one in
metropolitan Atlanta.

      On November 13, 1998, the Company purchased Lipscomb Concrete Cutting for
$4,252,000 of which $3,376,000 was cash and $876,000 was in the form of a note
due November 1, 1999, bearing interest at 6%.

      Both of these acquisitions are being accounted for as purchases and
accordingly, the result of operations of the acquired companies are included
from the date of acquisition.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

      The following discussion of the results of operations and financial
condition of Penhall International Corp., (Penhall) should be read in
conjunction with the Penhall's unaudited condensed consolidated financial
statements and footnotes thereto included in this quarterly report on Form 10-Q
and the Company's audited consolidated financial statements and footnotes
thereto included in the Registration Statement on Form S-4, as amended, filed
with the Securities and Exchange Commission.

GENERAL

      Penhall was founded in 1957 in Anaheim, California with one piece of
equipment, and today is one of the largest Operated Equipment Rental Services
companies in the United States. Penhall differentiates itself from other
equipment rental companies by providing specialized services in connection with
infrastructure projects through renting equipment along with skilled operators
to serve customers in the construction, industrial, manufacturing, governmental
and residential markets. In addition, Penhall complements its Operated Equipment
Rental Services with fixed-price contracts, which serve to market its operated
equipment rental services business and increase utilization of its operated
equipment rental fleet. Penhall provides its services from 30 locations in
eleven states, with a presence in some of the fastest growing states in terms of
construction spending and population growth.


      The operated equipment rental industry is a specialized niche of the
highly fragmented United States equipment rental industry, in which there are
approximately 17,000 companies. Penhall has taken advantage of consolidation
opportunities by acquiring small companies in targeted markets as well as by
establishing new offices in those markets. Since 1994, Penhall has effected six
strategic acquisitions, including Concrete Coring Company, an Austin-based
company acquired in 1995, Zig Zag Company, a Denver-based firm acquired in 1996,
Metro Concrete Cutting, an Atlanta-based company acquired in 1996, HSI, a
Minnesota-based firm acquired in April 1998, Daley Concrete Cutting, a South
Carolina-based division of U.S. Rentals acquired in October 1998 and Lipscomb
Concrete Cutting, a North Carolina-based company acquired in November 1998.
During the same period, Penhall established operations in four new markets by
opening offices in Las Vegas, Salt Lake City, Portland and Dallas.

      Penhall derives its revenues primarily from services provided for
infrastructure related jobs. Penhall's operated equipment rental services are
complemented by long-term fixed-price contracts. Approximately 53% of Penhall's
revenues are derived from highway-related projects, approximately 29% of
revenues are generated from building-related projects and the remainder of
revenues is generated from airport, residential and other projects. The
following table shows the breakdown of the components of revenue for the periods
indicated:

<PAGE>   20

      Revenue growth is influenced by infrastructure change, including new
construction, modification, natural disasters, such as the 1989 and 1994
earthquakes in Northern and Southern California. Other factors that influence
Penhall's operations are demand for operated rental equipment, the amount and
quality of equipment available for rent, rental rates and general economic
conditions. Historically, revenues have been seasonal, as weather conditions in
the spring and summer months result in stronger performance in the first and
fourth fiscal quarters than in the second and third fiscal quarters.

      The principal components of Penhall's operating costs include the cost of
labor, equipment rental fleet maintenance costs including parts and service,
equipment rental fleet depreciation, insurance and other direct operating costs.
Given the varied, and in some cases specialized, nature of its rental equipment,
Penhall utilizes a range of periods over which it depreciates its equipment on a
straight-line basis. On average, Penhall depreciates its equipment over an
estimated useful life of six years with a 10% residual value.


RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 1998 COMPARED TO THREE MONTHS ENDED DECEMBER 31,
1997

Revenues. Revenues for the three months ended December 31, 1998 ("Interim 1999")
were $33.1 million, an increase of $9.3 million or 39.3% over the three months
ended December 31, 1997 ("Interim 1998"). The growth in revenues is attributable
to the acquisition of HSI, which added $2.5 million of revenues in Interim 1999,
strength in the Company's operated equipment rental business in most of the
markets it serves, and the adverse impact that weather conditions had on Interim
1998's revenues.

      The Company operated through 30 locations in eleven states at December 31,
1998, compared to 21 locations in eight states at December 31, 1997. The
Company's equipment fleet grew from 450 to 556 or 23.5% during this period.

Gross Profit. Gross profit totaled $10.4 million in Interim 1999, an increase of
$3.2 million or 44.7% from Interim 1998. Gross profit as a percentage of
revenues increased from 30.2% in Interim 1998 to 31.3% in Interim 1999. The
increase in gross profit as percentage of revenues was primarily attributable to
a higher percentage of total revenues being derived from operated equipment
rental services in Interim 1999 as compared to Interim 1998. Gross margins for
operated equipment rental services are generally higher than for contract
services.

General and Administrative Expenses. General and administrative expenses for
Interim 1999 were $6.3 million, an increase of $1.2 million or 23.0% from
Interim 1998. The increase in these costs was caused by general and
administrative costs of HSI, Daley Concrete Cutting and Lipscomb concrete
cutting, all of which were included in Interim 1999 but not in Interim 1998.
After adjusting for the impact of these costs, general and administrative
expenses were $5.2 million, a 1.8% increase from Interim 1998.

Earnings Before Interest and Income Taxes. Earnings before interest and income
taxes increased $1.7 million or 64.5% from $2.6 million in Interim 1998 to $4.3
million in Interim 1999. This increase was primarily attributable to increased
revenues and higher gross profit margin in Interim 1999 as compared to Interim
1998.

Interest Expense. Interest expense in Interim 1999 was $3.9 million, an increase
of $3.7 million over Interim 1998. The substantial increase in interest expense
was directly attributable to the issuance of $100.0 million of Senior Notes, the
incurrence of $20.0 million of Term Loans, and borrowings of $5.5 million under
the revolving credit agreement.

Income Taxes. The effective tax rate changed from 50.7% of earnings before
income taxes in Interim 1998 to 20.3% of earnings before income taxes in Interim
1999. The lower effective tax rate in Interim 1999 is attributable to
reorganization costs related to the Transactions, which is not deductible for
tax purposes.

Net Earnings. Net earnings decreased by $.9 million from net earnings of $1.2
million in Interim 1998 to $.3 million in Interim 1999 for the reasons discussed
above.


SIX MONTHS ENDED DECEMBER 31, 1998 COMPARED TO SIX MONTHS ENDED DECEMBER 31,
1997

Revenues. Revenues for the six months ended December 31, 1998 (Interim 1999)
were $72.0 million, an increase of $19.9 million, or 38.2%, over the six months
ended December 31, 1997 ( Interim 1998). The increase was primarily attributable
to the acquisition of HSI in April 1998 and general strength in the construction
markets that the Company serves. HSI contributed $10.2 million of that increase.
Also contributing to the improvement was significantly better weather conditions
in November and December of Interim 1999.


Gross Profit. Gross profit totaled $21.4 million in Interim 1999, an increase of
$5.9 million, or 38.1%, from Interim 1998. Gross profit as a percentage of
revenues increased to 29.8% for Interim 1998, from 29.7% for Interim 1999. This
slight increase in gross profit as a percentage of revenues was primarily
attributable to higher equipment utilization in Interim 1999.
<PAGE>   21

General and Administrative Expenses. General and administrative expenses for
Interim 1999 were $23.5 million, an increase of $13.7 million, or 139.5%, over
Interim 1998. General and administrative expenses as a percentage of revenues
increased from 18.8% for Interim 1998, to 32.6% for Interim 1999. The
substantial increase in these costs was caused by an increase of $8.7 million in
stock compensation costs triggered by the Transactions and $3.3 million of costs
incurred with respect to the Mergers. After adjusting for the impact of these
unusual transaction related costs and the general and administrative costs
associated with the HSI, Daley and Lipscomb acquisitions, general and
administrative expenses were approximately $10.3 million, an increase of $.5
million.

Earnings (Loss) before Interest and Income Taxes. Earnings (loss) before
interest and income taxes went from earnings of $6.4 million in Interim 1998 to
a loss of $1.7 million in Interim 1999. The decrease in earnings before interest
and income taxes during Interim 1999 was primarily attributable to the
transaction costs discussed above. After adjusting for these transaction related
costs earnings before interest and income taxes improved from $6.4 million in
Interim 1998 to $10.3 million in Interim 1999, an increase of 61.7%.

Interest Expense. Interest expense in Interim 1999 was $6.5 million, an increase
of $6.0 million over Interim 1998. The substantial increase in interest expense
was directly attributable to the issuance of $100.0 million of Senior Notes, the
incurrence of $20.0 million of Term Loans, and borrowings of $5.5 million under
the revolving credit agreement in connection with the Transactions.

Income Taxes. The effective income tax rate decreased from 43.9% of earnings
before income taxes for Interim 1998 to 20.2% of loss before income taxes for
Interim 1999. The change in the effective tax rate was attributable to an
approximately $1.3 million of reorganization costs related to the Transactions
which is not deductible for tax purposes.

Net Earnings (Loss). Net earnings were $3.3 million in Interim 1998 compared to
a net loss of $6.5 million in Interim 1999. The decrease is due to the
transaction costs and increased interest expense discussed above.

LIQUIDITY AND CAPITAL RESOURCES

      Cash provided by operating activities for the six months ended December
31, 1997 was $7.2 million compared to a use of cash in operations of $11.3
million for the six months ended December 31, 1998. For the six months ended
December 31, 1998, the significant use of cash from operations primarily arose
from the stock compensation expense of $8.9 million, $3.3 million in costs
incurred with respect to the Mergers, disbursement of certain tax gross up
payments to shareholders totaling approximately $2.9 million and a substantial
increase in accounts receivable during that period.

      Management estimates that the Penhall Group's annual capital expenditures
will be approximately to $15.0 million for fiscal 1999, including replacement of
equipment and purchases of new equipment.

      Cash used in investing activities for the six months ended December 31,
1997 was $6.8 million as compared to $14.2 million for the six months ended
December 31, 1998. Such cash was primarily used for capital expenditures of $6.9
million for the six months ended December 31, 1997 and $7.6 million for the same
period in fiscal 1999. Also, in the six months ended December 31, 1998 cash used
in investing activities includes $6.7 million related to the acquisition of
Daley Concrete Cutting and Lipscomb Concrete Cutting.

      Net cash used in financing activities for the six months ended December
31, 1997 was $1.1 million as compared to cash provided by financing activities
of $26.1 million for the same period in fiscal 1999. Financing activities of the
Penhall Group are primarily the result of the Transactions for the six months
ended December 31, 1998 and borrowings and repayments of long-term debt.

      Historically, the Penhall Group has funded its working capital
requirements, capital expenditures and other needs principally from operating
cash flows. As a result of the Transactions, however, the Company has
substantial indebtedness and debt service obligations. As of December 31, 1998,
the Company and its subsidiaries had approximately $130.7 million of total
indebtedness outstanding (including the Notes) and a stockholders' deficit of
approximately $66.4 million.

      It is anticipated that the Company's principal uses of liquidity will be
to fund working capital, meet debt service requirements and finance the
Company's strategy of pursuing strategic acquisitions and expanding through
internal growth. The Company's principal sources of liquidity are expected to be
cash flow from operations and borrowings under the New Credit Facility. The New
Credit Facility consists of two facilities: (i) a six-year senior secured term
loan facility in an aggregate principal amount equal to $20.0 million (the "Term
Loan Facility"); and (ii) a six-year revolving credit facility in an aggregate
principal amount not to exceed $30.0 million (the "Revolving Credit Facility").
The Company drew $20.0 million of loans under the Term Loan Facility ("Term
Loans") on the closing date of the New Credit Facility in connection with the
Recapitalization. As of December 31, 1998, $24.5 million of additional
borrowings were available under the Revolving Credit Facility. The Term Loans
amortize on a quarterly basis commencing in September 2000 and are payable in
installments under a schedule set forth in the New Credit Facility. Advances
made under the Revolving Credit Facility ("Revolving Loans") are due and payable
in full at maturity. The Term Loans and the Revolving Loans are subject to
mandatory prepayments and reductions in the event of certain extraordinary
transactions or issuance's of debt and equity by the Company or any subsidiary
of the Company that guarantees amounts under the New Credit Facility. Such loans
are also required to 
<PAGE>   22

be prepaid with 75% of the Excess Cash Flow (as such term is defined in the New
Credit Facility) of the Company or, if the Company's Leverage Ratio (as such
term is defined in the New Credit Facility) is less than 4.75 to 1.0, 50% of
such Excess Cash Flow.

      The degree to which the Company is leveraged could have important
consequences to holders of the Notes, including, but not limited to, the
following: (i) the Company's ability to obtain additional financing for working
capital, capital expenditures, acquisitions, general corporate or other purposes
may be impaired; (ii) a substantial portion of the Company's cash flow from
operations must be dedicated to the payment of principal and interest on
indebtedness; (iii) the agreements governing the Company's long-term
indebtedness will contain restrictive financial and operating covenants that
could limit the Company's ability to compete and expand; (iv) the Company's
leverage may make it more vulnerable to industry-related or general economic
downturns and may limit its ability to withstand competitive pressures; and (v)
certain of the Company's borrowings are and will continue to be at variable
rates of interest, which exposes the Company to the risk of increased interest
rates.

NEW ACCOUNTING PRONOUNCEMENTS

      During 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. (Statement) 131, "Disclosures about Segments
of an Enterprise and Related Information," which establishes new standards for
reporting about operating segments in interim and annual financial statements.
Statement 131 is effective for fiscal years beginning after December 15, 1997
and does not need to be implemented for interim periods in the initial year of
application. The Company does not expect the adoption of Statement 131 to have
a material effect on its financial position or results of operations.

MARKET RISK

      The Company is exposed to interest rate changes primarily as a result of
its notes payable, including Senior Notes, Term Loan and Revolving Loan which
are used to maintain liquidity and fund capital expenditures and expansion of
the Company's operations. The Company's interest rate risk management objective
is to limit the impact of interest rate changes on earnings and cash flows and
to lower its overall borrowing costs. To achieve its objectives the Company
borrows primarily at fixed rates and has the ability to choose interest rates
under the Term Loan and Revolving Loan. The Company does not enter into
derivative or interest rate transactions for speculative purposes.

Year 2000

      The Year 2000 issue is the result of computer programs being written 
using two digits rather than four to define the applicable year. The Penhall 
Group has established an informal Year 2000 task force, and has developed a 
plan which lists the milestones achieved and yet to be completed to become Year 
2000 ready. A checklist of potential failure sources has been compiled and 
includes both information technology and embedded technology systems. The 
Penhall Group has completed its assessment of its information technology and 
embedded technology systems and has identified and taken measures to correct 
potential failures in those systems, including a recent upgrade of the hardware 
and software components of its information technology system. The Penhall Group 
is currently conducting the testing phase of its plan to determine whether the 
corrective measures which have been taken are adequate. The Penhall Group has 
not incurred significant costs to date in connection with the Year 2000 issue 
and expects to be Year 2000 ready by June 30, 1999 without incurring 
significant additional costs. However, delays in the implementation of Year 
2000 solutions, or the failure of the Penhall Group's information technology or 
embedded technology systems to operate properly in the Year 2000, could have a 
material adverse effect on the Penhall Group's business, results of operations 
or financial condition. Contingency plans have not been developed for all 
mission critical information and embedded technologies in the event Year 2000 
readiness is not met. The Penhall Group expects to have these contingency plans 
in place by June 30, 1999.

      Although the Penhall Group is uncertain as to the extent its customers 
may be affected by Year 2000 issues that require commitment of significant 
resources and may cause disruptions in its customers' businesses, the Penhall 
Group does not believe it has a material relationship with any one third party 
that would have a significant impact on the Penhall Group if that third party 
was not Year 2000 ready.
