                      W.W. Grainger, Inc., and Subsidiaries
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)



1.  BASIS OF STATEMENT PRESENTATION

The financial  statements and the related notes are condensed and should be read
in conjunction with the consolidated  financial statements and related notes for
the year ended  December 31, 1997,  included in the  Company's  Annual Report on
Form 10-K filed with the Securities and Exchange Commission.

The consolidated  financial  statements  include the accounts of the Company and
its subsidiaries. All significant intercompany transactions are eliminated.

The  consolidated  financial  statements  have been  retroactively  restated  to
reflect the 2-for-1  stock split  announced  on April 29, 1998  effective at the
close of business on May 11, 1998.  Computations  of basic and diluted  earnings
per share,  average  number of shares  outstanding,  and cash dividends paid per
share reflect this stock split.

The  Company  adopted  Statement  of  Financial  Accounting  Standards  No. 130,
"Reporting Comprehensive Income," effective January 1, 1998. As of September 30,
1998,  there was no recorded  tax effect  associated  with the foreign  currency
translation   adjustments  as  reported  in  the   Consolidated   Statements  of
Comprehensive Earnings.

Inventories  are  valued  at the  lower of cost or  market.  Cost is  determined
primarily by the last-in, first-out (LIFO) method.

The unaudited financial  information  reflects all adjustments which are, in the
opinion of  management,  necessary  for a fair  presentation  of the  statements
contained herein.

Checks  outstanding  of  $33,630,000  and  $54,218,000  were  included  in trade
accounts payable at September 30, 1998 and December 31, 1997, respectively.

2.  DIVIDEND

On October 28,  1998,  the Board of Directors  declared a quarterly  dividend of
$0.15 per share,  payable December 1, 1998 to shareholders of record on
November 9, 1998.

3.  SHARE REPURCHASE

On April 29, 1998, the Company's  Board of Directors  restored an existing share
repurchase  authorization to its original level of ten million shares.  Prior to
this  authorization,  less than  four  million  shares  remained  available  for
repurchase.  The number of shares have been  adjusted  for the May 1998  2-for-1
stock split announced on April 29, 1998, and will  automatically be adjusted for
any subsequent  stock splits.  Repurchases  are expected to be made from time to
time in open  market and  privately  negotiated  transactions.  The  repurchased
shares will be retained in the  Company's  treasury  and will be  available  for
general corporate purposes.

4.  EMPLOYERS'  DISCLOSURES  ABOUT  PENSIONS AND OTHER  POSTRETIREMENT  BENEFITS
    (SFAS No. 132)

Statement  of  Financial   Accounting  Standards  (SFAS)  No.  132,  "Employers'
Disclosure about Pensions and Other Postretirement  Benefits",  is effective for
fiscal years beginning after December 15, 1997. SFAS No. 132 revises  employers'
disclosures   about   pension  and  other   postretirement   benefit   plans  by
standardizing certain disclosure  requirements.  In accordance with the release,
the Company plans to adopt SFAS No. 132 for the year ended December 31, 1998.

5.  ACCOUNTING  FOR THE COSTS OF COMPUTER  SOFTWARE  DEVELOPED  OR OBTAINED  FOR
    INTERNAL USE (SOP 98-1)

Statement of Position (SOP) 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use", is effective for fiscal years beginning
after December 15, 1998. SOP 98-1 provides  guidance on accounting for the costs
of computer software developed or obtained for internal use.

The  Company  has not yet  determined  the  impact of  adopting  SOP 98-1 on its
results of  operations  or financial  condition.  The Company plans to adopt SOP
98-1 beginning January 1, 1999.

                     CONDITION AND THE RESULTS OF OPERATIONS

                              RESULTS OF OPERATIONS


THREE  MONTHS  ENDED  SEPTEMBER  30, 1998  COMPARED  WITH THE THREE MONTHS ENDED
SEPTEMBER 30, 1997:

Net Sales

Net sales of  $1,120,038,000  for the 1998 third quarter increased 5.0% from net
sales of $1,066,927,000 for the comparable 1997 period. There were 64 sales days
in both the 1998 and 1997  third  quarters.  The year  1998  will  have the same
number of sales days as did the year 1997 (255).

The sales increase of 5.0% for the 1998 third quarter, as compared with the 1997
third  quarter,   was  principally  volume  related.   This  increase  primarily
represented the effects of the Company's market  initiatives  which included new
product  additions,  and the National  Accounts,  Integrated  Supply, and Direct
Marketing programs.

Daily sales of seasonal products for the Company  increased  approximately 7% in
the 1998 third  quarter as compared  with the same 1997 period.  Many regions of
the country  experienced  warmer weather during the third quarter of 1998 versus
the  comparable  1997  period.  Sales  of all  other  products  for the  Company
increased  approximately  5% in the 1998 third quarter as compared with the same
1997 period.


Additional factors affecting the Company's third quarter 1998 sales growth were:

1.   A decline  in sales at  Acklands  -  Grainger  Inc.  (AGI),  the  Company's
     Canadian  subsidiary,  which resulted from a slowdown in sales to customers
     in the oil and other natural resources industries. An unfavorable change in
     the Canadian exchange rate also contributed to this decline.  The Company's
     daily sales growth rate, excluding AGI from both quarters,  would have been
     6.5% above the third quarter of 1997.

2.   The United Parcel  Service's (UPS) work stoppage,  which began on August 4,
     1997,  and lasted for more than 2 weeks.  The Company  estimated that sales
     were  approximately $14 million lower in August 1997 as a result of the UPS
     work  stoppage.  The  Company's  1998 third quarter sales growth rate would
     have been 3.6% above the comparable 1997 period,  after adjusting for these
     lost sales.

The Company's daily sales growth rate was 5.0% after excluding AGI from both the
1998 and 1997 periods,  and after  adjusting for the effect of the 1997 UPS work
stoppage.

Also  affecting the Company's  sales growth was the overall impact that the 1998
General Motors Corp. strike had on the U.S. economy.

The Company's Grainger branch-based business experienced selling price increases
of about 0.6% when comparing the third quarters of 1998 and 1997. Daily sales to
National  Account  customers  within  the  branch-based  business  increased  an
estimated 8%, on a comparable basis, over the 1997 third quarter.

                              RESULTS OF OPERATIONS


Net Earnings

Net  earnings  of  $56,089,000  in the 1998 third  quarter  decreased  0.7% when
compared to net earnings of $56,480,000 for the comparable 1997 period.  The net
earnings decrease was due to operating  expenses  (warehousing,  marketing,  and
administrative)  increasing  at a faster  rate than net sales,  higher  interest
expense, and the negative impact of unclassified-net, partially offset by higher
gross profit margins and higher interest income.

The  Company's  gross profit  margin  increased by 1.22  percentage  points when
comparing  the  third  quarters  of 1998 and  1997.  Of note  are the  following
favorable factors affecting the Company's gross profit margin:

1.  The Grainger branch-based business had selling price increases of 0.6% and a
    program to reduce product costs.

2.  The net change in product mix was favorable.  The sales of Lab Safety Supply
    (generally higher than average gross profit margins)  increased as a percent
    of total sales.  The sales of AGI (generally lower than average gross profit
    margins)  decreased as a percent of total sales.  These favorable changes in
    product  mix  were  partially  offset  by the  sales  of  seasonal  products
    (generally  lower than average gross profit  margins)  which  increased as a
    percent of total sales.


Operating expenses (warehousing,  marketing, and administrative) for the Company
increased  11.4%  for the 1998  third  quarter  as  compared  with the same 1997
period.  This rate of  increase  was  greater  than the rate of  increase in net
sales. The following  factors,  combined with a lower than expected  increase in
net sales,  contributed to this higher rate of increase:

   1. Operating expenses were higher as a result of the following initiatives:

      a. Continued expansion of the Company's integrated supply business;

      b. Start-up of the Grainger Custom Solutions business;

      c. Continued   development  of  the  Company's   full  service   marketing
         capabilities on the Internet; and

      d. Increased expenses supporting the Company's marketing initiatives.

Net Earnings (continued)


    2.  Operating  expenses  related  to  data  processing  were  higher  by  an
        estimated  $5,000,000  compared  with 1997,  as adjusted for 1998 volume
        increases.  This was primarily due to incurring expenses related to Year
        2000  compliance  and  the  ongoing  installation  of the  new  business
        enterprise system.

        For a more detailed discussion of the Year 2000 issue, see the Year 2000
        section included in this report.

    3.  Excluding the estimated effects of the incremental expenses described in
        points  1  and 2  above,  the  Company's  operating  expenses  increased
        approximately 8%.

Operating earnings for the third quarter of 1997 were negatively affected by the
UPS work stoppage which occurred in August 1997. The gross profit margin lost on
the estimated $14 million in lost sales,  along with the  incremental  operating
expenses  incurred  to  serve  customers  during  this  period,  resulted  in an
estimated negative effect on net earnings of about $0.03 per share.

Interest  income  increased  $358,000 for the third  quarter of 1998 as compared
with the same period in 1997.  This increase  resulted from higher average daily
invested balances.  Interest rates were relatively flat when comparing the third
quarters of each year.

Interest  expense  increased  $114,000 for the third quarter of 1998 as compared
with the same  period  in 1997.  This  increase  resulted  from  higher  average
interest rates paid on all outstanding  debt. The increase was partially  offset
by lower average borrowings.

Unclassified-net  had a  negative  effect on  earnings  before  income  taxes of
$1,330,000  for the third  quarter of 1998 as  compared  with the same period in
1997.  This  negative  effect  was  primarily  the  result of  foreign  currency
translation losses relating to the Company's  operations in Mexico and to a loss
on the sale of equipment.

The Company's effective income tax rate was 40.5% for the third quarters of both
1998 and 1997.

NINE MONTHS  ENDED  SEPTEMBER  30,  1998  COMPARED  WITH THE NINE  MONTHS  ENDED
SEPTEMBER 30, 1997:

Net Sales

Net sales of  $3,296,115,000  for the first nine months of 1998  increased  6.2%
from net sales of $3,103,689,000 for the comparable 1997 period.  There were 191
sales  days in the first nine  months of 1998 and 1997.  The year 1998 will have
the same number of sales days as did the year 1997 (255).

The sales  increase of 6.2% for the first nine months of 1998,  as compared with
the same 1997 period,  was principally  volume related.  This increase primarily
represented the effects of the Company's market  initiatives  which included new
product  additions,  and the National  Accounts,  Integrated  Supply, and Direct
Marketing programs.

Daily sales of seasonal products for the Company  increased  approximately 5% in
the first nine months of 1998 as compared  with the same 1997  period.  Sales of
all other products for the Company increased  approximately 6% in the first nine
months of 1998 as compared with the same 1997 period.

The Company's growth in daily sales for the first nine months of 1998 versus the
same 1997 period was  constrained by a decline in sales for AGI as discussed for
the third quarter of 1998. (See the Third Quarter Net Sales discussion  included
in this report.)

The Company  estimated  that August  1997 sales were  approximately  $14 million
lower as a result of the UPS work stoppage as discussed for the third quarter of
1998. (See the Third Quarter Net Sales discussion included in this report.)

Also  affecting the Company's  sales growth was the overall impact that the 1998
General Motors Corp. strike had on the U. S. economy.

The Company's Grainger branch-based business experienced selling price increases
of about 0.9% when comparing the first nine months of 1998 and 1997. Daily sales
to National  Account  customers within the  branch-based  business  increased an
estimated 10%, on a comparable basis, over the same 1997 period.

                     CONDITION AND THE RESULTS OF OPERATIONS

                              RESULTS OF OPERATIONS

Net Earnings

Net earnings of  $172,511,000  for the first nine months of 1998  increased 2.3%
when compared to net earnings of  $168,648,000  for the comparable  1997 period.
The net earnings  increase was lower than the sales  increase  primarily  due to
operating expenses (warehousing,  marketing, and administrative) increasing at a
faster rate than net sales,  lower interest income, and higher interest expense,
partially offset by higher gross profit margins.

The  Company's  gross  profit  margin  increased by 0.82  percentage  point when
comparing  the first  nine  months of 1998 and 1997.  Of note are the  following
favorable factors affecting the Company's gross profit margin:

1.  The Grainger branch-based business had selling price increases of 0.9% and a
    program to reduce costs.

2.  The  change in product  mix was  favorable.  The sales of Lab Safety  Supply
    (generally higher than average gross profit margins)  increased as a percent
    of total sales.  The sales of AGI (generally lower than average gross profit
    margins)  decreased  as a percent  of total  sales.  The  sales of  seasonal
    products  (generally lower than average gross profit margins) decreased as a
    percent of total sales.

Operating expenses (warehousing,  marketing, and administrative) for the Company
increased 10.6% for the first nine months of 1998 as compared with the same 1997
period.  This rate of  increase  was  greater  than the rate of  increase in net
sales. The following  factors,  combined with a lower than expected  increase in
net sales, contributed to this higher rate of increase:

1.  Operating expenses were higher as a result of the following initiatives:

    a.  Continued expansion of the Company's integrated supply business;

    b.  Start-up of the Grainger Custom Solutions business;

    c.  Continued   development   of  the  Company's   full  service   marketing
        capabilities on the Internet; and

    d.  Increased expenses supporting the Company's marketing initiatives.

Net Earnings (continued)

2.  Operating  expenses  related to data  processing were higher by an estimated
    $20,000,000 compared with 1997, as adjusted for 1998 volume increases.  This
    was primarily due to incurring  expenses related to Year 2000 compliance and
    the ongoing installation of the new business enterprise system.

    For a more  detailed  discussion  of the Year 2000 issue,  see the Year 2000
    section included in this report.

3.  Excluding the estimated  effects of the  incremental  expenses  described in
    points  1  and  2  above,  the  Company's   operating   expenses   increased
    approximately 7%.

Interest  income  decreased  $1,064,000  for the  first  nine  months of 1998 as
compared  with the same period in 1997.  This decrease  primarily  resulted from
lower  average  daily  invested  balances.  The decrease in interest  income was
partially offset by higher average interest rates earned.

Interest  expense  increased  $835,000  for the  first  nine  months  of 1998 as
compared  with the same  period in 1997.  This  increase  resulted  from  higher
average interest rates paid on all outstanding  debt. The increase was partially
offset by lower average borrowings.

Net earnings for the first nine months of 1997 were  negatively  affected by the
UPS work stoppage  which  occurred  during the third  quarter of 1997.  (See the
Third Quarter Net Earnings discussion included in this report.)

The Company's  effective  income tax rate was 40.5% for the first nine months of
both 1998 and 1997.

Year 2000

The Company uses various  software and  technology  that is affected by the Year
2000 issue. The Year 2000 issue is the result of computer programs being written
using two  digits  rather  than four to define  the  applicable  year.  Computer
programs  that have  date-sensitive  software may recognize a date using "00" as
the year 1900 rather than the year 2000.  This could result in a system  failure
or in miscalculations causing disruptions to operations,  including, among other
things,  a  temporary  inability  to  process  transactions,  send  invoices  to
customers,  or to engage in similar normal  business  activities.  The Year 2000
issue affects virtually all companies and organizations.

The Company has put in place project teams dedicated to implementing a Year 2000
solution and to improving the Company's overall systems capabilities.  The teams
are  actively  working to achieve the  objectives  of Year 2000  compliance  and
improved  internal  systems.  The work  includes  the  modification  of  certain
existing systems, a major new system initiative, replacing hardware and software
for other systems, the creation of contingency plans, and surveying suppliers of
goods and services with whom the Company does business.

The major new system  initiative,  in addition to solving some Year 2000 issues,
reduces the  complexity  which has  evolved  over time from the  development  of
in-house systems. This complexity, which makes it difficult to change and modify
systems  quickly,  has resulted in a  proliferation  of programs and  databases.
These issues will be addressed by the installation of a new business  enterprise
system to replace a majority of the Company's  primary  operating  systems.  The
major system  initiative has been undertaken to improve the Company's ability to
quickly respond to changing market conditions, to reduce the cost of maintaining
and supporting existing systems, and to leverage the use of information.

The Company is using a standard  methodology with three phases for the Year 2000
compliance  project.  Phase  I  included  conducting  a  complete  inventory  of
potentially affected areas of the business (including information technology and
non-  information  technology),   assessing  and  prioritizing  the  information
collected during the inventory, and completing detailed project plans to address
all key areas of the project.  Phase II includes the  remediation and testing of
all mission  critical  areas of the  project,  surveying  suppliers of goods and
services with whom the Company does  business,  and the creation of  contingency
plans to address potential Year 2000 related problems.  The Company is currently
in Phase II of the project.  Phase III of the project  includes the  remediation
and testing of non-mission critical areas of the project, and the implementation
of contingency plans as may be necessary.

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


Year 2000 (continued)

The Company is using both internal and external resources to reprogram, replace,
and test the software and hardware  for Year 2000  compliance.  Currently,  Year
2000 work for mission critical and most non-mission critical systems and testing
of all system revisions is planned to be completed in the third quarter of 1999.
The  expenses  associated  with this  project  include  both a  reallocation  of
existing internal  resources plus the use of outside services.  Project expenses
for 1997  amounted to an estimated  $13 million.  The total  remaining  expenses
associated  with the Year 2000  project are  estimated to be between $60 and $65
million. Due to the Year 2000 project and the major new system initiative,  1998
data processing  expenses will be higher than 1997. The data processing expenses
for 1998  are  estimated  to be a net $20 to $25  million  higher  than the 1997
expenses as adjusted for 1998 volume related changes.  It is estimated that 1999
data  processing  expenses will  approximate  1998  expenses,  adjusted only for
volume  related  changes.  It is  expected  that these  projects  will be funded
through the Company's operating cash flows.

In addition to addressing internal systems, the Company's Year 2000 project team
has  surveyed  suppliers  of goods  and  services  with  whom the  Company  does
business.  This is being done to  determine  the extent to which the  Company is
vulnerable to a third parties'  failure to remediate  their own Year 2000 issue.
However,  there can be no guarantee that the systems of other companies on which
the  Company's  systems  interact  will be timely  converted,  that a failure to
convert  by another  company,  or a  conversion  that is  incompatible  with the
Company's systems, would not have material adverse effect on the Company.

As  part  of  Phase  II of the  Year  2000  project,  the  Company  is  creating
contingency  plans to address  potential  Year 2000  related  problems  with key
business  processes.  The plans are expected to address  risks to the  Company's
systems as well as risks from third party suppliers,  customers, and others with
whom the Company does business.  It is recognized  that while the Company cannot
eliminate  all potential  risks,  the effect of the risks on the business can be
partially mitigated by creating and testing contingency plans. Contingency plans
for key business  processes are expected to be completed in the first quarter of
1999.

The  estimated  expenses  for these  projects and the dates by which the Company
will complete the Year 2000 work are based on  management's  current  assessment
and were derived utilizing numerous assumptions of future events,  including the
continued availability of certain resources,  third-party modification plans and
other factors.

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


Year 2000 (continued)

However, there can be no guarantee that these estimates will be achieved or that
all  components  of  Year  2000   compliance   will  be  addressed  as  planned.
Uncertainties  include,  but are not  limited to, the  availability  and cost of
personnel  trained in this area,  the ability to locate and correct all relevant
computer codes, and the sources and timeliness of various systems replacements.

Management  believes  that  failure to  address  the Year 2000 issue on a timely
basis could have a materially  adverse effect on the Company and is committed to
devoting the appropriate resources to ensure a Year 2000 solution.

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


                         LIQUIDITY AND CAPITAL RESOURCES


For the nine months ended  September  30,  1998,  working  capital  decreased by
$49,191,000.  The ratio of  current  assets to  current  liabilities  was 2.0 at
September 30, 1998 and 2.2 at December 31, 1997. The Consolidated  Statements of
Cash  Flows,  included in this  report,  detail the sources and uses of cash and
cash equivalents.

The  Company  continues  to  maintain  a low debt  ratio  and  strong  liquidity
position,  which  provides  flexibility  in funding  working  capital  needs and
long-term cash  requirements.  In addition to internally  generated  funds,  the
Company has various sources of financing  available,  including commercial paper
sales and bank borrowings under lines of credit and otherwise.  Total debt, as a
percent of  Shareholders'  Equity,  was 14.6% at September 30, 1998 and 12.2% at
December 31, 1997. For the first nine months of 1998,  $92,298,000 were expended
for  property,  buildings,  and  equipment,  and  $31,967,000  were expended for
capitalized software, for a total of $124,265,000.

For the first nine months of 1998,  the Company  repurchased  approximately  2.7
million shares of its common stock. The Company used internally  generated funds
and short-term  debt to fund 1998 share  repurchases.  As of September 30, 1998,
approximately  7.4 million  shares of common  stock remain  available  under the
repurchase  authorization.  (See Note 3 of the Notes to  Consolidated  Financial
Statements.)
