                  DAYTON SUPERIOR CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
           (AMOUNTS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
                                   (UNAUDITED)

(1)  CONSOLIDATED FINANCIAL STATEMENTS

     The interim consolidated financial statements included herein have been
     prepared by the Company, without audit, and include, in the opinion of
     management, all adjustments necessary to state fairly the information set
     forth therein. Any such adjustments were of a normal recurring nature.
     Certain information and footnote disclosures normally included in financial
     statements prepared in accordance with accounting principles generally
     accepted in the United States have been omitted, although the Company
     believes that the disclosures are adequate to make the information
     presented not misleading. It is suggested that these unaudited consolidated
     financial statements be read in conjunction with the consolidated financial
     statements and the notes thereto included in the Company's annual financial
     statements for the year ended December 31, 2002. The interim results may
     not be indicative of future periods.

(2)  ACCOUNTING POLICIES

     The interim consolidated financial statements have been prepared in
     accordance with the accounting policies described in the notes to the
     Company's consolidated financial statements for the year ended December 31,
     2002. While management believes that the procedures followed in the
     preparation of interim financial information are reasonable, the accuracy
     of some estimated amounts is dependent upon facts that will exist or
     calculations that will be made at year end. Examples of such estimates
     include changes in the deferred tax accounts and management bonuses. Any
     adjustments pursuant to such estimates during the fiscal quarter were of a
     normal recurring nature.

     (a) Fiscal Quarter -- The Company's fiscal year end is December 31. The
         Company's fiscal quarters are defined as the 13-week periods ending on
         a Friday near the end of March, June and September.

     (b) Inventories -- The Company values all inventories at the lower of
         first-in, first-out ("FIFO") cost or market. The Company provides net
         realizable value reserves which reflect the Company's best estimate of
         the excess of the cost of potential obsolete and slow moving inventory
         over the expected net realizable value. Following is a summary of the
         components of inventories as of March 28, 2003 and December 31, 2002:

     (c) Rental Equipment -- Rental equipment is manufactured or purchased by
         the Company for resale and for rent to others on a short-term basis.
         Rental equipment is recorded at the lower of FIFO cost or market and is
         depreciated over the estimated useful life of the equipment, three to
         fifteen years, on a straight-line basis. The balances as of March 28,
         2003 and December 31, 2002 are net of accumulated depreciation of
         $26,915 and $24,181, respectively. Rental revenues and cost of sales
         associated with rental revenue are as follows:

     (d) New Accounting  Pronouncements -- In June 2001, the FASB issued SFAS
         No. 141, "Business Combinations" and No. 142 "Goodwill and Other
         Intangible Assets." SFAS No. 141 revises the accounting for future
         business combinations to only allow the purchase method of accounting.
         In addition, the two statements preclude amortization of goodwill for
         periods beginning after December 15, 2001. Instead, an annual review
         of the recoverability of the goodwill and intangible assets is
         required. Certain other intangible assets continue to be amortized
         over their estimated useful lives.

         The Company adopted SFAS No. 142 effective January 1, 2002. As a result
         of adopting SFAS No. 142, the Company recorded a non-cash charge in the
         first quarter of 2002 of $17,140 ($19,894 of goodwill, less an income
         tax benefit of $2,754), which is reflected as a cumulative effect of
         change in accounting principle in the accompanying March 29, 2002
         consolidated statement of operations. This amount does not affect the
         Company's ongoing operations. The goodwill arose from the acquisitions
         of Dur-O-Wal in 1995, Southern Construction Products in 1999, and
         Polytite in 2000, all of which manufacture and sell metal accessories
         used in masonry construction. The masonry products market has
         experienced weaker markets and significant price competition, which has
         had a negative impact on the product line's earnings and fair value.

         In June 2001, the Financial Accounting Standards Board ("FASB") issued
         Statement of Financial Accounting Standards ("SFAS") No. 143,
         "Accounting for Asset Retirement Obligations." SFAS No. 143 requires
         that an obligation associated with the retirement of a tangible
         long-lived asset be recognized as a liability when incurred. Subsequent
         to initial measurement, an entity recognizes changes in the amount of
         the liability resulting from the passage of time and revisions to
         either the timing or amount of estimated cash flows. SFAS No. 143 is
         effective for financial statements issued for fiscal years beginning
         after June 15, 2002. The adoption of this pronouncement did not have a
         material impact on the Company's consolidated financial position,
         results of operations or cash flows.

         In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB
         Statements Nos. 4, 44, and 64, Amendment of FASB Statement No. 13, and
         Technical Corrections." SFAS No. 145 eliminates the requirement to
         classify gains and losses from the extinguishment of indebtedness as
         extraordinary, requires certain lease modifications to be treated the
         same as a sale-leaseback transaction, and makes other non-substantive
         technical corrections to existing pronouncements. SFAS No. 145 is
         effective for fiscal years beginning after May 15, 2002, with earlier
         adoption encouraged. The adoption of this pronouncement did not have a
         material impact on the Company's consolidated financial position,
         results of operations or cash flows.

         In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs
         Associated with Exit or Disposal Activities." The standard requires
         companies to recognize costs associated with exit or disposal
         activities when they are incurred rather than at the date of a
         commitment to an exit or disposal plan. Examples of costs covered by
         the standard include lease termination costs and certain employee
         severance costs that are associated with a restructuring or other exit
         or disposal activity. SFAS No. 146 is to be applied prospectively to
         exit or disposal activities initiated after December 31, 2002. The
         adoption of this pronouncement did not have a material impact on the
         Company's consolidated financial position, results of operations or
         cash flows.

         In December 2002, the FASB issued SFAS No. 148, "Accounting for
         Stock-Based Compensation-Transition and Disclosure." SFAS 148 amends
         SFAS No. 123, "Accounting for Stock-Based Compensation." Although it
         does not require use of fair value method of accounting for stock-based
         employee compensation, it does provide alternative methods of
         transition. It also amends the disclosure provisions of Statement 123
         and APB Opinion No. 28, "Interim Financial Reporting," to require
         disclosure in the summary of significant accounting policies of the
         effects of an entity's accounting policy with respect to stock-based
         employee compensation on reported net income and earnings per share in
         annual and interim financial statements. SFAS No. 148's amendment of
         the transition and annual disclosure requirements is effective for
         fiscal years ending after December 15, 2002. The amendment of
         disclosure requirements of APB Opinion No. 28 is effective for interim
         periods beginning after December 15, 2002. Although the Company has not
         changed to the fair value method, the disclosure requirements of this
         statement have been adopted.

         In November 2002, the FASB issued Interpretation (FIN) No. 45,
         "Guarantor's Accounting and Disclosure Requirements for Guarantees
         Including Indirect Guarantees of Indebtedness of Others." FIN No. 45
         elaborates on the disclosures to be made by a guarantor in its interim
         and annual financial statements about its obligations under certain
         guarantees that it has issued. It also clarifies that a guarantor is
         required to recognize, at the inception of a guarantee, a liability for
         the fair value of the obligation undertaken in issuing the guarantee.
         The disclosure requirements in this interpretation are required for
         financial statements of periods ending after December 15, 2002. The
         initial measurement provisions of the interpretation are applicable on
         a prospective basis for guarantees issued or modified after December
         31, 2002. The adoption of this pronouncement did not have a material
         impact on the Company's consolidated financial position, results of
         operations or cash flows.

         In January 2003, the FASB issued FIN No. 46, "Consolidation of Variable
         Interest Entities, an Interpretation of APB No. 50." FIN No. 46
         requires certain variable interest entities to be consolidated by the
         primary beneficiary of the entity if the equity investors in the entity
         do not have the characteristics of a controlling financial interest or
         do not have sufficient equity at risk for the entity to finance its
         activities without additional subordinated financial support from other
         parties. FIN No. 46 is effective for all new variable interest entities
         created or acquired after January 31, 2003. For variable interest
         entities created or acquired prior to February 1, 2003, the provisions
         of FIN No. 46 must be applied for the first interim or annual period
         beginning after June 15, 2003. The Company does not believe this
         pronouncement will have a material impact on its financial position,
         results of operations and cash flows.

(e)      Stock Options -The Company measures compensation cost for stock options
         issued using the intrinsic value-based method of accounting in
         accordance with Accounting Principles Board Opinion (APB) No. 25. If
         compensation cost for the Company's stock options had been determined
         based on the fair value method of SFAS No. 123, "Accounting for
         Stock-Based Compensation," the Company's net income would have been
         reduced to the unaudited pro forma amounts as follows:

         Because the SFAS No. 123 method of accounting has not been applied to
         options granted prior to January 1, 1995, the resulting pro forma
         compensation cost may not be representative of that to be expected
         in future years.

     (f) RECLASSIFICATIONS -- Certain reclassifications have been made to the
         2002 amounts to conform to their 2003 classifications.

</TABLE>

As of March 28, 2003, the Company's credit facility consisted of (i) a $50,000
revolving credit facility maturing June 2006, (ii) a $30,000 acquisition
facility, converting from revolving loans into term loans four years from the
closing and maturing June 2006 and (iii) term loan facilities in an aggregate
principal amount of $122,000, consisting of a $23,500 tranche A facility
maturing June 2006 and a $98,500 tranche B facility maturing June 2008.

The credit facility provides that the Company repay (i) the tranche A facility
in quarterly installments commencing March 2002, (ii) the tranche B facility in
quarterly installments, commencing March 2002 and (iii) the acquisition facility
in equal quarterly installments commencing in June 2004. The credit facility has
several interest rate options which reprice on a short-term basis.

At March 28, 2003, the Company had outstanding letters of credit of $9,269, and
the Company had available borrowings of $13,331 under its revolving credit
facility.

The average borrowings, maximum borrowings and weighted average interest rates
on the revolving credit facility for the periods indicated were as follows:

The credit facility contains certain restrictive covenants which require that,
among other things, the Company maintain a minimum interest coverage ratio, not
exceed a certain leverage ratio, maintain a minimum EBITDA, as defined, and
limit its capital expenditures. The Company was in compliance with its loan
covenants as of March 28, 2003.

The Senior Subordinated Notes (the "Notes") have a principal amount of $170,000
and mature in June 2009. The Notes were issued at a discount, which is being
accreted to the face value using the effective interest method and is reflected
as interest expense. The Notes were issued with warrants that allow the holder
to purchase 117,276 of the Company's Common Shares for $0.01 per share. The
Company's wholly-owned domestic subsidiaries (Aztec Concrete Accessories, Inc.;
Trevecca Holdings, Inc.; Dayton Superior Specialty Chemical Corp.; Symons
Corporation; and Dur-O-Wal, Inc.) have guaranteed the Notes. The wholly-owned
foreign subsidiaries of the Company are not guarantors of the Notes and do not
have any credit arrangements senior to the Notes. The following supplemental
consolidating condensed balance sheets as of March 28, 2003 and December 31,
2002 and the supplemental consolidating condensed statements of operations and

(4) STOCK OPTION PLANS

The Company has a stock option plan which provides for an option exercise price
equal to the stock's market price on the date of grant. The options are
accounted for under APB Opinion No. 25, under which no compensation costs have
been recognized. Had compensation cost for these plans been determined
consistent with SFAS No. 123, the Company's net loss for the three fiscal months
ended March 28, 2003 and March 29, 2002 would have been increased to the
following pro forma amounts:

Because the SFAS No. 123 method of accounting has not been applied to options

not be representative of that to be expected in future years.

(5) SEGMENT REPORTING

In an effort to reduce cost and enhance customer responsiveness, the Company
consolidated its overhead structure from five marketing arms down to two
effective January 1, 2003. Accordingly, the Company changed its reporting as a
result of this consolidation such that it now reports under two segments:
Construction Products Group and Symons. Construction Products Group and Symons
sell primarily to external customers and are differentiated by their products
and services, both of which serve the construction industry. Construction
Products Group sells concrete accessories, which are used in connecting forms
for poured-in-place concrete walls, anchoring or bracing for walls and floors,
supporting bridge framework and positioning steel reinforcing bars; masonry
accessories, which are placed between layers of brick and concrete blocks and
covered with mortar to provide additional strength to walls; paving products
which are used in the construction and rehabilitation of concrete roads,
highways, and airport runways to extend the life of the pavement; and
construction chemicals which are used in conjunction with its other products.



                                       18
<PAGE>
Symons sells and rents reusable engineered forms and related accessories used in
the construction of concrete walls, columns and bridge supports to hold concrete
in place while it hardens and construction chemicals which are used in
conjunction with its other products.

Sales between Construction Products Group and Symons are recorded at normal
selling price by the selling segment and at cost for the buying segment, with
the profit recorded as an intersegment elimination. Segment assets include
accounts receivable; inventories; property, plant, and equipment; rental
equipment; and an allocation of goodwill. Corporate and unallocated assets
include cash, prepaid income taxes, future tax benefits, and financing costs.
Export sales and sales by non-U.S. affiliates are not significant.

Information about the income (loss) of each segment and the reconciliations to
the consolidated amounts for the three fiscal months ended March 28, 2003 and
March 29, 2002 follows. The 2002 amounts have been reclassified to conform to
the 2003 classification.

(6) FACILITY CLOSING AND SEVERANCE EXPENSES

During the first quarter of 2003, the Company approved and began implementing
plans to reduce overall Company headcount in order to keep its cost structure in
alignment with its net sales. The plan encompassed approximately 50 employee
terminations, and the amount of severance expense during the first quarter of
2003 was $395.

The Company had also approved and implemented several facility closing and
severance plans prior to December 31, 2002. The Company had established reserves
for the expected future costs of severance, lease payments and other
post-closing facility maintenance costs. Below is a summary of the amounts
charged against the facility closing and severance reserves in 2003 and 2002:

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

OVERVIEW

We believe we are the largest North American manufacturer and distributor of
metal accessories and forms used in concrete construction and of metal
accessories used in masonry construction. Although almost all of our products
are used in concrete or masonry construction, the function and nature of the
products differ widely. As of March 28, 2003, we have two principal operating
divisions, which are organized around the following functional areas of
expertise:

        -    Construction Products Group and
        -    Symons.

RESULTS OF OPERATIONS

The following table summarizes our results of operations as a percentage of net
sales.

</TABLE>

Net sales for the Construction Products Group decreased $8.7 million, or 15.6%,
to $47.4 million in the first quarter of 2003 from $56.1 million in the first
quarter of 2002, primarily due to the weaker markets in the first quarter of
2003 compared to 2002. In addition, the harsh winter weather in the first
quarter of 2003 caused delays in the start of construction projects.

Net sales of Symons products decreased 7.1% to $24.8 million for the first
quarter of 2003 compared to $26.6 million in the first quarter of 2002,
primarily due to lower rental revenues and decreased sales of new products due
to the weaker markets and the harsh winter weather in the first quarter of 2003
compared to 2002. This was partially offset by increased sales of used rental
fleet as we continue to optimize rental fleet utilization.

GROSS PROFIT

Gross profit for the first quarter of 2003 was $21.0 million, a decrease of $5.5
million from $26.5 million in the first quarter of 2002. This was due primarily
to the decreased revenues discussed previously, offset partially by the cost
savings realized from the facility closing and severance plans implemented by
management.

Gross margin was 30.8% in the first quarter of 2003, decreasing from 33.8% in
the same quarter of 2002. This was due primarily to the combination of the fixed
cost impact on the unfavorable sales volume and unfavorable pricing, both of
which are attributable to our weaker markets in 2003 compared to 2002.

OPERATING EXPENSES

Selling, general, and administrative expenses ("SG&A expenses") decreased $3.7
million to $19.6 million in the first quarter of 2003, from $23.2 million in the
first quarter of 2002, primarily due to the cost savings realized from the
implementation of the facility closing and severance plans.



                                       23

During the first quarter of 2003, we approved and began implementing plans to
further reduce overall headcount in order to keep our cost structure in
alignment with our net sales. The plan encompassed approximately 50 employee
terminations, and the amount of severance expensed during the first quarter of
2003 was $0.4 million.

During 2001, we approved and began implementing two plans to exit certain
manufacturing and distribution facilities and to reduce overall headcount in
order to keep our cost structure in alignment with our net sales. As a result of
the continued implementation of the plans, we incurred $0.1 million of facility
closing and severance expense in the first quarter of 2002, which is related
primarily to facility relocation activities.

Below is a summary of the amounts charged against the facility closing and
severance reserve during the first quarter of 2003 and 2002:

Amortization of intangibles was $0.1 million in the first quarters of both 2003
and 2002.

OTHER EXPENSES

Interest expense increased slightly to $8.1 million in the first quarter of 2003
from $8.0 million in the first quarter of 2002. This was due to higher average
borrowings in the first quarter of 2003 when compared to the first quarter of
2002, offset partially by the lower interest rates in 2003.

Construction Products Group's income before income taxes of $1.3 million in the
first quarter of 2003 decreased from $3.9 million in the first quarter of 2002.
This was primarily due to the lower net sales volumes in 2003, offset partially
by the cost savings realized from the facility closing and severance plans
implemented by management.

Symons' income before income taxes was $4.9 million in the first quarter of 2003
compared to $4.0 million in the first quarter of 2002. This was due primarily to
the cost savings realized from the facility closing and severance plans
implemented by management.

Corporate expenses increased slightly to $11.1 million in the first quarter of
2003 from $10.9 million in the first quarter of 2002.

Elimination of profit on intersegment sales was $2.2 million in the first
quarter of 2003 compared to $2.0 million in the first quarter of 2002, due
primarily to a change in the mix of intersegment product sales.

NET LOSS BEFORE CUMULATIVE EFFECT OF CHANGE IN ACCOUNTING PRINCIPLE

The effective tax rate in the first quarter of 2003 was 25.0%, which is
different from the statutory rate, primarily due to the unfavorable impact of
permanent book/tax differences. The net loss before cumulative effect of change
in accounting principle for the first quarter of 2003 was $(5.4) million
compared to a loss of $(3.0) million in the first quarter of 2002 due to the
factors described above.




                                       25
<PAGE>


CUMULATIVE EFFECT OF CHANGE IN ACCOUNTING PRINCIPLE

In June 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 141, "Business Combinations" and
SFAS No. 142 "Goodwill and Other Intangible Assets." SFAS No. 141 revises the
accounting for future business combinations to allow only the purchase method of
accounting. In addition, the two statements preclude amortization of goodwill
for periods beginning after December 15, 2001. Instead, an annual review of the
recoverability of the goodwill and intangible assets is required. Certain other
intangible assets continue to be amortized over their estimated useful lives.

We adopted these statements effective January 1, 2002. As a result of adopting
SFAS No. 142, we recorded a non-cash charge in the first quarter of 2002 of
$17.1 million ($19.9 million of goodwill, less an income tax benefit of $2.8
million), which is reflected as a cumulative effect of change in accounting
principle. This amount does not affect our ongoing operations. The goodwill
arose from the acquisitions of Dur-O-Wal in 1995, Southern Construction Products
in 1999, and Polytite in 2000, all of which manufacture and sell metal
accessories used in masonry construction. The masonry products market has
experienced weaker markets and significant price competition, which has had a
negative impact on the product line's earnings and fair value.

NET LOSS

The net loss for the first quarter of 2003 was $5.4 million compared to a loss
of $20.2 million in the first quarter of 2002 due to the factors described
above.

LIQUIDITY AND CAPITAL RESOURCES

Our key statistics for measuring liquidity and capital resources are net cash
provided by operating activities, capital expenditures and amounts available
under the revolving credit facility.

Our capital requirements relate primarily to capital expenditures, debt service
and the cost of acquisitions. Historically, our primary sources of financing
have been cash from operations, borrowings under our revolving credit facility
and the issuance of long-term debt and equity.

Net cash used in operating activities in the first quarter of 2003 was $9.4
million compared to a use of $15.4 million in the first quarter of 2002.

Net cash used in investing activities was $4.9 million in the first quarter of
2003 compared to a use of $2.3 million in the first quarter of 2002. Property,
plant and equipment additions decreased to $2.5 million in the first quarter of
2003 from $3.8 million in the first quarter of 2002, as we continue to closely
monitor our spending with our markets being weaker. Rental equipment additions,
net of proceeds from sales of rental equipment, were a $2.4 million use of cash
in the first quarter of 2003 compared to a $1.6 million source of cash in the
first quarter of 2002. This is due to the implementation of our plan to continue
to replace older traditional forming rental fleet with newer European clamping
systems.

</TABLE>

At March 28, 2003, of the $50.0 million revolving credit facility that was
available to us, $27.4 million of borrowings were outstanding, along with $9.3
million of letters of credit, with the remaining $13.3 million available for
borrowing. Approximately $9.2 million of the $30.0 million acquisition facility
had been drawn and was outstanding. Of the $23.5 million tranche A facility,
$22.3 million had been drawn and $18.6 million was outstanding at March 28,
2003. All of the $98.5 million tranche B facility had been drawn and
approximately $97.3 million was outstanding at March 28, 2003.

Our long-term debt borrowings, net of repayments for the first quarter of 2003
were $16.0 million compared to $14.5 million in the first quarter of 2002.

We may from time to time may seek to retire our outstanding debt through cash
purchases and/or exchanges for equity securities, in open market purchases, or
in privately negotiated transactions or otherwise. Such repurchases or
exchanges, if any, will depend on prevailing market conditions, our liquidity
requirements, contractual restrictions and other factors. The amounts involved
may be material.

At March 28, 2003, working capital was $67.5 million, compared to $65.8 million
at December 31, 2002. The increase in working capital is attributable to normal
seasonal working capital growth.

We intend to fund future acquisitions with cash, securities or a combination of
cash and securities. To the extent we use cash for all or part of any future
acquisitions, we expect to raise the cash from our business operations, from
borrowings under our credit facility or, if feasible and attractive, by issuing
long-term debt or additional common shares.

SEASONALITY

Our operations are seasonal in nature with approximately 55% of sales
historically occurring in the second and third quarters. Working capital and
borrowings fluctuate with the volume of our sales.

INFLATION

We do not believe inflation had a significant impact on our operations over the
past two years. In the past, we have been able to pass along to our customers a
portion of the increases in the price of steel (our principal raw material). We
may not be able to pass on steel price increases in the future.

CRITICAL ACCOUNTING POLICIES

In preparing our consolidated financial statements, we follow accounting
principles generally accepted in the United States of America. These principles
require us to make certain estimates and apply judgments that affect our
financial position and results of operations. We continually review our
accounting policies and financial information disclosures. There have been no
material changes in our policies or estimates since December 31, 2002.

FORWARD-LOOKING STATEMENTS

This Form 10-Q includes, and future filings by us on Form 10-K, Form 10-Q, and
Form 8-K, and future oral and written statements by us and our management may
include certain forward-looking statements, including (without limitation)
statements with respect to anticipated future operating and financial
performance, growth opportunities and growth rates, acquisition and divestitive
opportunities and other similar forecasts and statements of expectation. Words
such as "expects," "anticipates," "intends," "plans," "believes," "seeks,"
"estimates" and "should," and variations of these words and similar expressions,
are intended to identify these forward-looking statements. Forward-looking
statements by us and our management are based on estimates, projections, beliefs
and assumptions of management and are not guarantees of future performance. We
disclaim any obligation to update or revise any forward-looking statement based
on the occurrence of future events, the receipt of new information, or
otherwise.

Actual future performance, outcomes and results may differ materially from those
expressed in forward-looking statements made by us and our management as the
result of a number of important factors. Representative examples of these
factors include (without limitation) the cyclical nature of nonresidential
building and infrastructure construction activity, which can be affected by
factors outside our control such as weakness in the general economy, a decrease
in governmental spending, interest rate increases, and changes in banking and
tax laws; our ability to successfully identify, finance, complete and integrate
acquisitions; increases in the price of steel (our principal raw material) and
our ability to pass along such price increases to our customers; the effects of
weather and seasonality on the construction industry; increasing consolidation
of our customers; the mix of products we sell; the competitive nature of our
industry; and the amount of debt we must service. This list is not intended to
be exhaustive, and additional information can be found in our annual report on


                                       28
<PAGE>

Form 10-K for the year ended December 31, 2002. In addition to these factors,
actual future performance, outcomes and results may differ materially because of
other, more general, factors including (without limitation) general industry and
market conditions and growth rates, domestic economic conditions, governmental
and public policy changes and the continued availability of financing in the
amounts, at the terms and on the conditions necessary to support our future
business.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

At March 28, 2003, we had financial instruments that were sensitive to changes
in interest rates. These financial instruments consisted of:

     -    $170.0 million of Senior Subordinated Notes, with a book value of
          $159.9 million;

     -    $202.0 million credit facility, consisting of:

               -    $50.0 million revolving credit facility, $27.4 million of
                    which was outstanding at March 28, 2003;

               -    $30.0 million acquisition facility, $9.2 million of which
                    was drawn and outstanding at March 28, 2003;

               -    $23.5 million term loan tranche A, $22.3 million of which
                    has been drawn and $18.6 million was outstanding at March
                    28, 2003; and

               -    $98.5 million term loan tranche B, all of which has been
                    drawn and $97.3 million was outstanding at March 28, 2003;

     -    $4.3 million in capital lease obligations; and

     -    $1.2 million in other fixed-rate, long-term debt.

The Senior Subordinated Notes bear interest at 13.0% on the $170.0 million of
principal and mature in 2009. The estimated fair value of the notes, based on a
trading price of $83 per unit at March 28, 2003, is $141.1 million.

Our credit facility has several interest rate options, which re-price on a
short-term basis. Accordingly, the fair value of the credit facility
approximates its $152.5 million face value. The weighted average interest rate
at March 28, 2003 was 4.8%.

Other long-term debt consists of a.) $1.1 million of debentures previously held
by the Dayton Superior Capital Trust, with a fair value of $1.8 million and b.)
a $0.1 million, 7.0% loan due in installments of $32 thousand per year with an
estimated fair value of $0.1 million.

In the ordinary course of our business, we also are exposed to price changes in
raw materials (particularly steel bar and rod and steel flat plate) and products
purchased for resale. The prices of these items can change significantly due to
changes in the markets in which our suppliers operate. We generally do not use
financial instruments to manage our exposure to changes in commodity prices.

ITEM 4.  CONTROLS AND PROCEDURES.

Within the ninety days prior to the date of this report, we carried out an
evaluation, under the supervision and with the participation of the Company's
management, including our Chief Executive Officer along with our Chief Financial
Officer, of the effectiveness of the design and operation of our disclosure
controls and procedures pursuant to Exchange Act Rule 13a-14. Based upon that
evaluation, our Chief Executive Officer along with our Chief Financial Officer
concluded that our disclosure controls and procedures are effective in timely
alerting them to material information relating to the Company (including its
consolidated subsidiaries) required to be included in our periodic SEC filings.

There have been no significant changes in our internal controls or in other
factors that could significantly affect internal controls subsequent to the date
we carried out this evaluation.
