              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)
                               September 30, 1999


1.  Basis of Presentation

The  accompanying  unaudited  condensed  consolidated  financial  statements  of
O'Reilly Automotive, Inc. and Subsidiaries (the "Company") have been prepared in
accordance with generally accepted  accounting  principles for interim financial
information and 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.
Operating  results for the three and nine months ended  September 30, 1999,  are
not  necessarily  indicative  of the results  that may be expected  for the year
ended  December 31, 1999.  For further  information,  refer to the  consolidated
financial  statements  and footnotes  thereto  included in the Company's  Annual
Report on Form 10-K for the year ended December 31, 1998.

2.  Debt

The  Company  has  unsecured  credit  facilities  totaling  $175  million.   The
facilities are comprised of a $125 million  five-year  revolving credit facility
which includes a $5 million  sub-limit for the issuance of letters of credit and
a $50  million  five-year  term  loan  facility.  These  credit  facilities  are
guaranteed by the subsidiaries of the Company and currently bear interest at the
London  Interbank  Offered Rate ("LIBOR") plus 0.50%. The Company is required to
meet various financial covenants as defined in the credit agreement.

3.  Secondary Offering

On March 31, 1999, the Company  completed a public offering of 3,340,000  shares
of common stock,  3,000,000 of which were issued by the Company resulting in net
proceeds  of $106.8  million.  A  portion  of the  proceeds  was used to repay a
significant  amount of the  outstanding  indebtedness  of the Company  under its
credit  facility.  The  remaining  portion of the proceeds  will be used to fund
future expansion.  On April 7, 1999, the Company issued 501,000 shares of common
stock related to the Company's portion of the over-allotment option resulting in
net proceeds to the Company of $17.9 million.

4.  Business Acquisition

Effective  January 31, 1998, the Company acquired all of the outstanding  common
shares  of Hi-Lo  Automotive,  Inc.  and its  subsidiaries  ("Hi/LO")  for $49.3
million or $4.35 per common share.  This acquisition has been accounted for as a
purchase by recording  the assets and  liabilities  of Hi/LO at their  estimated
fair values at the acquisition  date. The excess of net assets acquired over the
purchase price, which totaled  approximately $9.7 million, has been applied as a
reduction to the acquired property and equipment.

The consolidated  results of operations of the Company include the operations of
Hi/LO from the acquisition  date.  Unaudited Pro Forma  consolidated  results of
operations  assuming the  purchase was made at the  beginning of each period are
shown below: (amounts in thousands, except per share data)

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

Unless  otherwise  indicated,  "we," "us," "our" and similar  terms,  as well as
references to the "Company" or "O'Reilly" refer to O'Reilly Automotive, Inc. and
its subsidiaries.

Results of Operations

Product  sales for the third  quarter of 1999  increased  by $35.6  million,  or
20.6%,  over product sales for the third quarter of 1998.  Product sales for the
first nine months of 1999  increased  by $114.6  million,  or 25.1% over product
sales for the first nine  months of 1998.  This is due to the opening of 14 net,
new O'Reilly  stores  during the last quarter of 1998 and the opening of 50 net,
new stores  during the first  three  quarters  of 1999,  in  addition to a 11.6%
increase in comparable  store product sales (O'Reilly  stores increased 6.7% and
HiLo stores  increased  19.0%).  At September  30, 1999,  we operated 541 stores
compared to 477 stores at September 30, 1998.

Gross profit  increased  26.9% from $69.3 million (or 40.1% of product sales) in
the third  quarter of 1998 to $88.0  million (or 42.2% of product  sales) in the
third quarter of 1999.  Gross profit for the first nine months  increased  29.3%
from  $186.2  million (or 40.8% of product  sales) in 1998 to $240.8  million or
(42.2% of  product  sales) in 1999.  The  increase  in gross  profit  margin was
attributable to continued improvement to our product acquisition programs,  some
of which were related to conversions of product lines in the Hi-Lo stores.

Operating,  selling,  general and  administrative  expenses  ("OSG&A  expenses")
increased  $11.9 million from $53.9  million (or 31.2% of product  sales) in the
third quarter of 1998 to $65.8 million (or 31.6% of product  sales) in the third
quarter of 1999.  OSG&A  expenses  increased  $36.5 million from $146.2  million
(32.0% of product  sales) in the first nine months of 1998 to $182.7 million (or
32.0% of product  sales) in the first  nine  months of 1999.  The dollar  amount
increase  in OSG&A  expenses  resulted  from the  addition  of team  members and
resources in order to support the increased level of our operations.

Other expense decreased by $1.4 million in the third quarter of 1999 compared to
the third  quarter  of 1998 and  decreased  by $1.4  million  for the first nine
months of 1999 compared to the first nine months of 1998.  The overall  decrease
in other expense is due to the repayment of a significant  amount of our debt in
the first quarter of 1999, thereby reducing interest expense.

Our estimated  provision for income taxes  increased from 38.0% of income before
income taxes in the third quarter and the first nine months of 1998 to 38.1% and
38.2%,  respectively  in the same periods in 1999. The increase in the effective
income tax rate was primarily due to changes in the mix of taxable  income among
the states in which we operate.

Principally,  as a result  of the  foregoing,  net  income  increased  from $8.4
million or 4.8% of product  sales in the third  quarter of 1998 to $13.4 million
or 6.4% of product  sales in the third quarter of 1999 and from $21.9 million or
4.8% of products sales in the first nine months of 1998 to $33.8 million or 5.9%
of product sales in the first nine months of 1999.

Liquidity and Capital Resources

Net cash of $33.5  million was  provided by operating  activities  for the first
nine  months of 1999 as  compared  to $16.7  million  of cash used by  operating
activities for the first nine months of 1998.  This increase was principally the
result of improved  operating  results and  increases in income  taxes  payable,
offset by increases in inventory and accounts  receivable.  These  increases are
the result of the addition of new stores and increased  sales levels in existing
and newly opened stores and the results of product line conversions.

Net cash used in investing  activities  has decreased from $84.5 million in 1998
to $46.4  million in 1999  primarily  due to the  acquisition  of Hi/LO in early
1998, partially offset by the proceeds of the sale of property and equipment.

Cash provided by financing  activities  has decreased from $100.5 million in the
first nine months of 1998 to $13.9 million in the first nine months of 1999. The
decrease was primarily due to the  substantial  reduction of debt with the funds
generated by the secondary offering in the first quarter of 1999, as well as the
scheduled principal payments on debt. Additionally,  cash provided by operations
has funded growth without having to increase our use of the credit facilities.

Aside from the 50 net,  new stores  opened in the first nine months of 1999,  we
plan to open an additional 30 net new stores during the 4th quarter of 1999. The
funds  required  for such  planned  expansions  will be  provided  by  operating
activities,  short-term  investments  and the existing and available bank credit
facilities.

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

Management  believes  that the cash  expected  to be  generated  from  operating
activities,  existing  cash and  short-term  investments,  existing  bank credit
facilities  and trade credit will be  sufficient to fund our short and long-term
capital and liquidity needs for the foreseeable future.

Inflation and Seasonality

We have been  successful,  in many cases, in reducing the effects of merchandise
cost increases  principally by taking  advantage of vendor  incentive  programs,
economies of scale  resulting from  increased  volume of purchases and selective
forward  buying.  As a  result,  we do not  believe  our  operations  have  been
materially affected by inflation.

Our  business is seasonal to some extent  primarily as a result of the impact of
weather  conditions  on store sales.  Store sales and profits have  historically
been higher in the second and third quarters  (April through  September) of each
year than in the first and fourth quarters.

Year 2000 Readiness Disclosure

We have  appointed an internal Year 2000 issue project  manager and  remediation
team and have adopted a four phase approach of assessment,  remediation, testing
and contingency  planning.  The scope of the project  includes our review of all
internal software,  hardware and operating systems and an assessment of the risk
to our  business  posed by any lack of vendor  preparedness  with respect to the
Year 2000 issue.  We have  completed  the  initial  assessment  of all  internal
systems, are progressing with the remediation and testing phases, and have begun
contingency  planning for information  technology  systems. We believe that this
approach of assessment (including  prioritization by business risk), remediation
(including  conversions  to new  software),  testing of necessary  changes,  and
contingency planning will minimize the business risk of the Year 2000 issue from
internal systems.

We utilized internal personnel to correct, replace and test our software for the
Year 2000 project. The total cost of the project was approximately  $200,000. Of
the total  project  cost,  approximately  $25,000  represented  the  purchase of
replacements or upgrades of software and hardware,  which were  capitalized.  We
expensed the remaining portion of the project cost as incurred during 1999.

We have established  ongoing  communications with all our significant vendors to
monitor their progress in resolving their issues related to the Year 2000 issue.
Many of such vendors have informed us that they are making substantial  progress
in resolving their Year 2000 issue. However, the most likely worst case scenario
for us  would  entail  failure  of one or more  of our  significant  vendors  to
continue operations (even temporarily) following transition to the year 2000. We
have  also  contacted  suppliers  of  products  significant  to  our  operations
containing  embedded chips to monitor their progress in resolving issues related
to the Year 2000 issue.  No material  issues have been  identified  to date as a
result of these contacts.  We cannot  guarantee that our business  partners will
adequately  address  issues related to the Year 2000 issue in a timely manner or
that the failure of our business partners to correct these issues would not have
a material adverse effect on the Company.

We have  completed  contingency  plans  to be used in the  event  of a  business
interruption  caused  by the Year  2000  issue  for  some,  but not all,  of our
internal information technology systems. Such plans are being developed for some
of our other  systems.  Elements  of our  contingency  plans  include  switching
vendors and utilizing back-up systems that do not rely on computers.

Forward-Looking Statements

Certain  statements  contained  in  this  quarterly  report  on  Form  10-Q  are
