                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.     ACCOUNTING POLICIES AND BASIS OF PRESENTATION

           The Annual Report on Form 10-K for the year ended December 31, 1997,
for Kevco, Inc. includes a summary of significant accounting policies and should
be read in conjunction with this Form 10-Q. The accompanying consolidated
financial statements of Kevco, Inc. and its wholly-owned subsidiaries ("Kevco"
or the "Company") have been prepared pursuant to the rules and regulations of
the Securities and Exchange Commission ("SEC"). Accordingly, they do not include
all of the information and footnotes required by generally accepted accounting
principles ("GAAP") for complete financial statements. All significant
intercompany transactions and accounts have been eliminated.

           In the opinion of management, the consolidated financial statements
contain all adjustments, consisting only of normal recurring adjustments,
considered necessary for a fair statement of the balance sheets as of September
30, 1998 and December 31, 1997, the statements of income for the three-month and
nine-month periods ended September 30, 1998 and 1997 and the statements of cash
flows for the nine-month periods ended September 30, 1998 and 1997. The results
of operations for the three-month and nine-month periods ended September 30,
1998 are not necessarily indicative of the results of operations for the entire
fiscal year ending December 31, 1998.

2.     ACQUISITIONS

           In December 1997, the Company acquired Shelter Components Corporation
(the "Shelter Acquisition") and the inventory and certain distribution rights
from Shepherd Products Company (the "Shepherd Acquisition"), for total purchase
prices approximating $144.8 million and $8.0 million, respectively. The
acquisitions were made utilizing borrowings under the Company's amended and
restated credit facility and, in the case of the Shelter Acquisition, net
proceeds from the issuance of $105 million of 10 3/8% senior subordinated notes
due 2007. Each of the acquisitions was accounted for as a purchase and the
results of operations of the acquired companies were included in the
consolidated results of operations of the Company from their respective
acquisition dates. As a result of such acquisitions, approximately $90.9 million
of goodwill was recorded by the Company, which reflects the adjustments
necessary to allocate the individual purchase prices to the fair value of assets
acquired, liabilities assumed and additional purchase liabilities recorded.
Additional purchase liabilities included approximately $1.7 million for
severance and related costs associated primarily with the elimination of certain
administrative and corporate positions recorded in connection with the Shelter
Acquisition in December, $0.4 million of which is outstanding at September 30,
1998. The Company expects to complete its termination of employees during 1998.

4.     CREDIT AGREEMENT

           In December 1997, Kevco and its lender entered into the second
amended and restated credit agreement, which was subsequently amended on
February 12, 1998 (the "Credit Agreement") at closing of the Shelter Acquisition
(see Note 2) to allow for aggregate senior borrowings of up to $125 million
comprised of a revolving credit facility of $45 million and a term loan facility
of $80 million. The revolving credit facility and $40 million of the term loan
facility mature in 2003 with the remaining term loan facility maturing in 2004.
The term loan and revolving credit facilities are collateralized by
substantially all of the assets of the Company and its subsidiaries as well as
the capital stock of such subsidiaries.

           In addition to funds available under the Credit Agreement, the
Company issued $105 million of 10 3/8% senior subordinated notes due 2007 (the
"Notes") under the indenture dated as of December 1, 1997, as supplemented (the
"Indenture"), to complete the acquisition of Shelter. Interest is payable on
June 1 and December 1 of each year commencing June 1, 1998. The Notes are
redeemable, in whole or in part, at the option of the Company, at any time on or
after December 1, 2002, at the redemption prices set forth in the Indenture. In
addition, at any time on or before December 1, 2000, the Company may redeem up
to 35% of the original aggregate principal amount of the Notes with the net
proceeds of a public equity offering at a redemption price equal to 110.375% of
the principal amount thereof, plus accrued and unpaid interest and liquidated
damages, if any, thereon to the date of redemption.

           The Credit Agreement and Indenture contain certain restrictions and
conditions that include cash flow and various financial ratio requirements, and
limitations on incurrence of debt or liens, acquisitions of property and
equipment, distributions to stockholders and certain events constituting a
Change of Control (as defined in the agreements). At September 30, 1998, the
Company was in violation of a financial covenant contained in the Credit
Agreement which has been waived by the Company's lenders through a retroactive
amendment to the Credit Agreement. The Company is currently negotiating a
modification of the Credit Agreement which management expects to be effective
December 31, 1998.

           Basic earnings per share excludes dilution, and diluted earnings per
share reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised and converted into common stock.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

GENERAL

           The following discussion includes the operations of Kevco for each of
the periods discussed. This discussion and analysis should be read in
conjunction with the Company's Annual Report on Form 10-K for the year ended
December 31, 1997.

           The Company recognizes revenues from product sales at the time of
shipment (or the time of product receipt, in the case of direct shipments from
suppliers to customers). In some cases the Company sells on a commission basis.
Commissions are recognized when earned and represent amounts earned in selling,
warehousing and delivering products for certain manufacturers of building
products with whom the Company has distribution agreements. Commission
arrangements do not require inventory investments or receivables financing, and
therefore are significantly less expensive to the Company than traditional
sales. To the extent the volume of items warehoused and shipped under commission
arrangements increases faster or slower than the volume of items related to
traditional sales, changes in net sales may not be representative of actual
increases or decreases in shipment volume.

           As discussed below, the Company acquired Shelter Components in
December 1997. Since that time, the Company has been integrating Shelter into
Kevco by, among other things, consolidating certain corporate functions,
consolidating overlapping distribution warehouses from 48 facilities to 34 and
integrating multiple Shelter and Kevco computer systems into one. Management
believes the consolidation and integration activities and related costs will
diminish, on a declining scale, with such activities and costs substantially
complete by the end of 1999.

ACQUISITIONS

           Effective December 1, 1997, the Company acquired approximately 95.5%
of the common stock of Shelter through a tender offer for a purchase price of
$17.50 per share of common stock of Shelter; the Company acquired the remaining
untendered shares through a subsequent merger for a like price. The Shelter
Acquisition was accounted for as a purchase and, accordingly, the operating
results have been included in the operating results of the Company since
December 1, 1997. As a result of the Shelter Acquisition, approximately $84.1
million of goodwill was recorded by the Company, which reflects the acquisition
costs in excess of the fair value of net assets acquired. On June 27, 1997,
prior to the acquisition of Shelter by Kevco, Shelter acquired the net assets of
Plastic Solutions, Inc., a manufacturer of injection molded plastic parts, for
approximately $0.9 million in cash and $3.5 million in notes payable to the
sellers.

           On December 12, 1997, the Company consummated the acquisition of the
inventory and certain distribution rights of certain building products
distributed by the manufactured housing and recreational vehicle division of
Shepherd Products Company for a cash purchase price of $6.0 million, with an
additional $2.0 million payable over a five year period following the
acquisition and an additional $2.0 million payable over a period of up to seven
years upon the satisfaction of certain conditions.

</TABLE>


COMPARISON OF THREE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997

           Net sales increased by $136.1 million, or 138.2%, to $234.6 million
for the three month period ended September 30, 1998 from $98.5 million for the
comparable 1997 period. The net sales increase primarily resulted from the
effect of the Shelter Acquisition in December 1997.

           Gross profit increased by $17.3 million, or 135.2%, to $30.1 million
for the three month period ended September 30, 1998 from $12.8 million for the
comparable 1997 period due primarily to the Shelter Acquisition. Gross profit,
as a percent of net sales, decreased to 12.8% for the three month period ended
September 30, 1998 from 13.1% for the comparable 1997 period. The decrease in
gross profit, as a percent of net sales, was related primarily to the effect of
wood products margins which, affected by lower than historical lumber prices,
continued to be lower than historical levels, to start-up costs related to the
opening of two wood products plants in Arizona and North Carolina (such wood
products represent approximately 19% of net sales) and to increased costs as a
result of the consolidation efforts to eliminate duplicate facilities resulting
from the Shelter Acquisition, as well as an otherwise general decline in
margins.

           Selling, general and administrative expenses increased by $14.5
million, or 131.8%, to $25.5 million for the three month period ended September
30, 1998 from $11.0 million for the comparable 1997 period. The increase was
primarily due to costs associated with the Shelter Acquisition and related
integration. Selling, general and administrative expenses, as a percent of net
sales, decreased to 10.9% for 1998 from 11.1% for the comparable 1997 period.
Although selling, general and administrative expense, as a percent of net sales,
decreased from the prior comparable period, in order to maintain high levels of
customer service in a period of considerable consolidation and integration of
Shelter distribution operations (including integration of information systems),
the Company has incurred costs significantly in excess of anticipated amounts
which have negatively impacted earnings and cash flow relating to, among other
things, contract labor, overtime and freight charges. The Company has also
encountered longer than anticipated start-up periods for two new wood products
facilities that were opened earlier this year.


                                       10
<PAGE>   11

           Interest expense increased by $4.5 million to $5.4 million for the
three months ended September 30, 1998 from $0.9 million for the comparable 1997
period principally due to borrowings related to the acquisitions of Shelter and
Shepherd.

           Net income decreased by $1.0 million, or 66.7%, to $0.5 million for
the three months ended September 30, 1998 from $1.5 million for the comparable
1997 period. The decrease is attributable primarily to a decrease in gross
margin percentage, an increase in selling, general and administrative expenses
and increased interest expense as described above.

COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997

           Net sales increased by $406.6 million, or 149.5%, to $678.6 million
for the nine month period ended September 30, 1998 from $272.0 million for the
comparable 1997 period. The net sales increase primarily resulted from the
effect of the Shelter Acquisition in December 1997 as well as a reported
manufactured housing shipment increase of 7.0% from January through August 1998,
as compared to the prior period. Sales to the manufactured housing industry
represented approximately 77% of net sales for the nine months ended September
30, 1998.

           Gross profit increased by $54.2 million, or 147.3%, to $91.0 million
for the nine month period ended September 30, 1998 from $36.8 million for the
comparable 1997 period due primarily to the Shelter Acquisition. Gross profit,
as a percent of net sales, decreased to 13.4% for the nine month period ended
September 30, 1998 from 13.6% for the comparable 1997 period. The decrease in
gross profit, as a percent of net sales, was related primarily to the fact that
wood products margins, affected by lower than historical lumber prices,
continued to be lower than historical levels, to start-up costs related to the
opening of two wood products plants in Arizona and North Carolina (such wood
products represent approximately 19% of year to date net sales) and to increased
costs in the third quarter as a result of the consolidation efforts to eliminate
duplicate facilities resulting from the Shelter Acquisition, as well as an
otherwise general decline in margins.

           Selling, general and administrative expenses increased by $41.6
million, or 144.9%, to $70.3 million for the nine month period ended September
30, 1998 from $28.7 million for the comparable 1997 period. The increase was
primarily due to costs associated with the Shelter Acquisition and related
integration. Selling, general and administrative expenses, as a percent of net
sales, decreased to 10.4% for 1998 from 10.6% for the comparable 1997 period.
Although selling, general and administrative expense, as a percent of net sales,
decreased from the prior comparable period, in order to maintain high levels of
customer service in a period of considerable consolidation and integration of
Shelter distribution operations (including integration of information systems),
the Company has incurred costs significantly in excess of anticipated amounts
which have negatively impacted earnings and cash flow relating to, among other
things, contract labor, overtime and freight charges. The Company has also
encountered longer than anticipated start-up periods for two new wood products
facilities that were opened earlier this year.

           Interest expense increased by $13.2 million to $15.6 million for the
nine months ended September 30, 1998 from $2.4 million for the comparable 1997
period principally due to borrowings related to the acquisitions of Shelter and
Shepherd.

           Net income decreased by $0.3 million, or 4.9%, to $5.8 million for
the nine months ended September 30, 1998 from $6.1 million for the comparable
1997 period. The decrease is due primarily to a decrease in gross margin
percentage, an increase in selling, general and administrative expenses and
increased interest expense as described above.


LIQUIDITY AND CAPITAL RESOURCES

           The Company's growth has been financed through cash flow from
operations, borrowings under its bank credit facilities, proceeds from the
November 1996 initial public offering, proceeds from the issuance of the Notes
and the expansion of trade credit. Net cash used by operating activities was
$13.9 million and capital expenditures were $8.9 million for the nine months
ended September 30, 1998. Kevco is obliged to make payments on various capital
leases in varying amounts, maturing through 2007 as well as payments under
various noncompete and consulting agreements, related to recent acquisitions, in
varying amounts, through 2002.

           In December 1997, the Company acquired Shelter for an aggregate
purchase price of approximately $144.8 million. In connection with the
acquisition of Shelter, the Company entered into the Credit Agreement, which
increased the aggregate borrowings available under the existing credit facility
to $125.0 million consisting of an $80.0 million term loan facility and a $45.0
million revolving credit facility. The revolving credit facility and a portion
of the term loan mature in 2003 with the remaining term loan portion maturing in
2004.

           Borrowings under the term loan and revolving credit facilities
require monthly, bi-monthly or quarterly interest payments (depending on whether
interest accrues based on prime rate or LIBOR) calculated as a blend of the
bank's prime rate and LIBOR based on pricing options selected by the Company
plus a margin determined by operating statistics of the Company. The term loan
and revolving credit facilities are collateralized by substantially all of the
assets of the Company and its subsidiaries as well as the capital stock of such
subsidiaries. The Credit Agreement contains certain restrictions and conditions
that include cash flow and various financial ratio requirements, and limitations
on incurrence of debt or liens, acquisitions of property and equipment,
distributions to stockholders and certain events constituting a Change of
Control (as defined in the Credit Agreement). At September 30, 1998, the Company
was in violation of a financial covenant contained in the Credit Agreement which
has been waived by the Company's lenders through a retroactive amendment to the
Credit Agreement. The Company is currently negotiating a modification of the
Credit Agreement which management expects to be effective December 31, 1998.

           In addition to the funds available under the amended credit facility,
the Company issued $105.0 million of the Notes under the Indenture to complete
the acquisition of the outstanding shares of Shelter. The Indenture contains
certain covenants that include, but are not limited to, restrictions or
limitations on the following: the incurrence of additional debt or liens, the
payment of dividends by the Company, the payment of dividends by restricted
subsidiaries to the Company, the sale of certain assets, the ability to
consolidate with or merge into another person, the entering into certain
transactions with affiliates and the engagement in certain lines of business.

ASSET MANAGEMENT

           The Company actively manages its assets and liabilities through
compensating its corporate and facility managers for receivable collection,
inventory control and profits in relation to these and other net assets
employed.

           For the nine months ended September 30, 1998, days sales in average
receivables was approximately 25 days, days sales in average inventory was
approximately 41 days and days sales in average payables was approximately 27
days.


YEAR 2000

           The Year 2000 problem concerns the inability of information systems
to properly recognize date-sensitive information beyond January 1, 2000.

           Kevco has begun a project to bring software and systems into Year
2000 compliance in time to minimize any significant detrimental effects on
operations. The project covers information systems infrastructure, financial and
administrative systems, operating systems, other non-information systems
equipment and significant vendors and customers.

           The Company has adopted a five level process toward Year 2000
compliance: (1) awareness; (2) assessment (identification of where failures may
occur, solutions and workarounds and plans to repair or replace), (3) renovation
(repair, replace or retire systems that cannot properly process Year 2000
dates); (4) validation and (5) implementation. At September 30, 1998, the first
two levels have been substantially completed (except with respect to third
parties as discussed below) and level three is in varying stages of completion.

           The Company is utilizing internal personnel, contract programmers and
vendors to identify Year 2000 noncompliance problems, modify code and test the
modifications. In some cases, non-compliant software and hardware will be
replaced.

           The Company relies on third party suppliers for products, raw
materials, utilities and other key services. Interruption of supplier operations
due to Year 2000 issues could affect Company operations through reduced sales,
reduced inventory levels and cash flow reductions. The Company is currently
evaluating the status of suppliers' efforts to become Year 2000 compliant and to
determine alternatives and contingency plan requirements. Approaches to reducing
risks of interruption due to supplier failures will vary. These alternatives and
contingency plans, once developed, are intended to provide a means of managing
risk, but cannot eliminate the potential for disruption due to third party
failure.

           The Company is also dependent upon customers for sales and cash flow.
Year 2000 interruptions in customers' operations could result in reduced sales,
increased inventory or receivable levels and cash flow reductions. While these
events are possible, the Company is, however, taking steps to monitor the status
of customers as a means of determining risks and alternatives.


                                       13
<PAGE>   14

           The Company's distribution centers and manufacturing facilities rely
on control systems, which include inventory and production monitoring and
warehouse management. Failure of these systems could result in disruption of
delivery of product to customers in a timely manner. The Company is evaluating
alternatives and contingency plans to mitigate these risks.

           The Company also relies on various financial applications, such as
order processing and collection systems. In the event of failure of order
processing, the Company's ability to fulfill customer demands could be impaired.
In the event of failure of collection systems, the Company may not be able to
properly apply payments to customer balances or correctly determine cash
balances, and then only to the extent that manual or other alternative processes
were not able to meet processing requirements. These applications are in various
stages of completion.

           The current estimate of incremental costs to complete the Year 2000
project is $600,000, of which approximately $150,000 has already been incurred
and the remainder is expected to be incurred over the next nine months. While
the Company believes its efforts will provide reasonable assurance that material
disruptions will not occur due to internal failure, the potential for
interruption still exists. In addition, there is a risk that the Company's plans
for achieving Year 2000 compliance will not be completed on time. However, as
part of the plan, the Company would be aware in advance and steps would be taken
to mitigate this risk.

FORWARD-LOOKING STATEMENTS

           Certain statements contained in this quarterly report consist of
forward-looking statements that involve risks and uncertainties, including, but
not limited to, the Company's substantial leverage and its effects on the
Company's ability to obtain additional capital as needed, the Company's ability
to integrate its operations and successfully implement new management
information systems, the Company's success in addressing and remediating Year
2000 related issues, the Company's ability to operate its new manufacturing
facilities, customer demand for manufactured housing and recreational vehicles,
the effect of economic conditions, the impact of raw materials prices, the
Company's ability to maintain profitability in the event of the loss of a
significant customer and other risks detailed from time to time in the reports
filed by the Company with the Securities and Exchange Commission, including the
Company's Annual Report on Form 10-K.
