                                                                    ATTACHMENT I


                    IBM ANNOUNCES THIRD-QUARTER 2001 RESULTS

      ARMONK, N.Y., October 16, 2001 . . . IBM today announced third-quarter
2001 diluted earnings per common share of $.90, a 17 percent decrease compared
with diluted earnings per common share of $1.08 in the third quarter of 2000.
Third-quarter 2001 net income was $1.6 billion, a 19 percent decline from $2.0
billion in the year-earlier period. IBM's third-quarter 2001 revenues totaled
$20.4 billion, down 6 percent (3 percent at constant currency) compared with the
third quarter of 2000.

      Louis V. Gerstner, Jr., IBM chairman and chief executive officer, said:
"The third quarter saw an acceleration of the fundamental shift in customer
buying behavior that is altering our industry's landscape. Customers now
allocate an increasing percentage of their spending to solutions, not boxes. The
major beneficiary of this change, of course, has been IBM Global Services.
Another very important beneficiary, however, has been IBM's middleware software,
since many of the major software solutions providers now recommend IBM
middleware as their preferred platform.

      "Finally, and perhaps surprising to some, another major beneficiary of the
industry shift has been IBM's powerful high-end zSeries servers, as customers
all over the world see the value of server consolidation. In the third quarter,
zSeries MIPS grew 42 percent and have grown by more than 40 percent in each
quarter of 2001.

      "Turning to our individual units, Services continued its double-digit
growth, excluding maintenance, and the backlog increased by nearly $2 billion
from last quarter. Software had an outstanding quarter and we are increasing
share in every important area of our software portfolio. Servers also had a
strong quarter with major share gains in the UNIX market. The PC segment of our
industry remains in trouble, and this negatively affected our PC and hard disk
drive businesses. As expected, our Microelectronics business was weak," Mr.
Gerstner said.

      "IBM's results for the first nine months of this year include $63 billion
of revenue, $5.4 billion of net profit -- both even with last year -- and $2.2
billion of free cash flow, double last year's amount. This is a remarkable
record, given that many technology companies have been reporting huge revenue
declines and vastly lower profits or losses for the first time in many years.
IBM's balance sheet remains among the strongest in the technology industry or
any industry."

      In the Americas, third-quarter revenues were $9.1 billion, a decline of 6
percent (5 percent at constant currency) from the same period of 2000. Revenues
from Europe/Middle East/Africa were $5.7 billion, up 1 percent (4 percent at
constant currency). Asia-Pacific revenues fell 5 percent (up 5 percent at
constant currency) to $4.1 billion. OEM revenues decreased 28 percent (27
percent at constant currency) to $1.5 billion.

      Revenues from Global Services, including maintenance, grew 5 percent (9
percent at constant currency) in the third quarter to $8.7 billion. Global
Services revenues, excluding maintenance, increased 7 percent (11 percent at
constant currency). IBM signed $10 billion in services contracts and concluded
the quarter with a total services contract backlog of approximately $97 billion.
The overall gross profit margin in Global Services improved by 1.8 points year
over year to 28.4 percent.

      Hardware revenues declined 21 percent (18 percent at constant currency) to
$7.5 billion from the 2000 third quarter. Revenues from z900 mainframe servers
grew strongly. Revenues from the iSeries mid-market servers increased in all
geographic areas, while pSeries revenues declined in part because customers were
awaiting the new high-end "Regatta" servers, which were announced in early
October. Personal computer revenues fell significantly, reflecting continued
weakness and price pressures in this market. Revenues from IBM's high-end
storage product family -- known as "Shark" -- increased year over year.
Microelectronics revenues decreased substantially, as expected, principally due
to the cyclical downturn that is affecting the worldwide semiconductor and OEM
markets.

      Software revenues grew 10 percent (14 percent in constant currency) to
$3.2 billion compared to the prior year's third quarter. Middleware revenues,
which comprise approximately 80 percent of IBM's overall software revenues, grew
18 percent at constant currency and operating system revenues increased 3
percent year over year. WebSphere revenues increased 75 percent, MQ Series
revenues more than doubled and DB2 revenues climbed 31 percent (excluding
revenues from the acquisition of the Informix database business, which was
successfully completed in the third quarter).

      Global Financing revenues decreased 4 percent (2 percent at constant
currency) in the third quarter to $822 million.

      Revenues from the Enterprise Investments/Other area, which includes
products for specialized customer uses, declined 24 percent (21 percent at
constant currency) year over year to $244 million. This decline was expected,
resulting from IBM's strategy to shift development and distribution of these
products to third-party companies.

      The company's total gross profit margin improved to 36.2 percent in the
2001 third quarter from 35.4 percent in the third quarter of 2000.

      Total third-quarter expenses were $5.1 billion, up 5 percent compared with
the year-earlier period. Selling, general and administrative expenses were flat
and include a charge resulting from workforce-balancing actions. Research and
development expenses also were flat. Other income declined primarily due to
writedowns of certain equity investments. The company continues to focus on
expense reductions through increased use of e-procurement, on-line learning and
other actions related to IBM's ongoing e-business transformation.

      IBM's tax rate in the third quarter was 29.5 percent compared with 30.0
percent in the third quarter of last year.

      IBM spent approximately $1.8 billion on share repurchases in the third
quarter. The average number of basic common shares outstanding in the quarter
was 1.73 billion compared with 1.76 billion shares in the same period of 2000.
There were 1.72 billion basic common shares outstanding at September 30, 2001.

      Net income for the nine months ended September 30, 2001 was $5.4 billion,
or $3.03 per diluted common share, compared with net income of $5.4 billion, or
$2.97 per diluted common share, in the year-earlier period. Revenues for the
nine months ended September 30, 2001 were $63.0 billion, flat (up 5 percent at
constant currency) compared with $62.8 billion for the nine months of 2000.

      The company's debt in support of operations, excluding global financing,
increased $1.1 billion from year-end 2000 to $2.2 billion, reflecting the
acquisition of the Informix database business. This resulted in a
debt-to-capitalization ratio of 11 percent at September 30, 2001. Global
financing debt declined $1.1 billion from year-end 2000 to a total of $26.4
billion, resulting in a debt-to-equity ratio of 6.7 to 1.

      Certain comments made by John Joyce or myself during this call may be
      characterized as forward looking under the Private Securities Litigation
      Reform Act of 1995.

      Those statements involve a number of factors that could cause actual
      results to differ materially.

      Additional information concerning these factors is contained in the
      company's filing with the SEC. Copies are available from the SEC, from the
      IBM web site, or from us in Investor Relations.

And at this time, let me turn the call over to John Joyce, IBM's Senior Vice
President and Chief Financial Officer.

Thanks, Hervey. Good afternoon.

We're pleased with our 3rd-quarter results -- especially in this tough
environment.

      o     $1 billion 600 million in AFTER-TAX profit.
      o     $2 billion in Free Cash Flow -- generated from
      o     Over $20 billion in revenues.

Our results continued to show strong resilience -- for the same two fundamental
reasons as in prior quarters --

      o     First, we again gained share in key business areas -- services,
            high-end servers, and software -- because we had the products and
            services -- in other words, the solutions -- that customers wanted
            in this environment.

      o     Second, we continued to benefit from the strength of our broad
            portfolio and our business model -- with its financial core of
            annuity-like businesses.

            And just as important -- particularly in this economy -- our balance
            sheet remains very strong.

Before I get into the details of our 3rd quarter, let me describe how September
11 affected our results. Here's what we generally saw:

      o     For that third of our business that is annuity-like and generated by
            ongoing operations -- outsourcing, maintenance, host-based software
            -- revenue was unaffected.

      o     In hardware and distributed software -- which is driven by new
            orders and new shipments of products -- a significant amount of
            revenue comes in the last month of any given quarter. September
            business, therefore, is critical.

            o     As best we can measure, deferrals were mainly in the U.S.
<Page>

            o     The biggest impacts were to storage subsystems, Business
                  Innovation Services, and Intel-based servers.
            o     Let me add that we saw further slowing of already weak orders
                  for PCs, associated HDDs, as well as OEM Microelectronics.
            o     On the other hand, our software and high-end servers remained
                  very strong.

      o     The heaviest concentration of all these deferrals was in the
            Financial Services and Insurance sectors, as you would expect. And
            we are working with these customers as they deal with their
            priorities. While it is too early to know how much of this business
            will eventually be booked -- in some areas like Outsourcing, we see
            a very strong pipeline of opportunity.

Clearly, this environment is putting more pressure on many technology companies.
But it is also providing the investment community a very useful tool for
identifying long-term winners.

We have said that history will not necessarily repeat itself, and we continue to
believe this.

      The next generation of e-business is about a powerful industry shift --
      the integration of computing and communications to achieve competitive
      advantage. It's not about just piece-parts.

So, a major shift is underway in customer buying patterns -- in favor of
powerful, fully integrated servers, software, and services. This shift plays
directly to the strength of IBM's product, services, and technology portfolio.

      Even though customers may have slowed their investment in IT in this
      economic environment -- they remain focused on this shift towards
      integration.

            o     They're still building an infrastructure that is scalable,
                  robust and secure.
            o     They're focused on returns -- on how fast can they get their
                  cash back.
            o     But they also want to make sure the investments they make
                  today are consistent with long-term plans to tie front-end
                  processes to
<Page>

                  back-end processes, and to exploit the flow of information
                  in-between.

As you've seen all year long, this customer shift clearly is helping us -- even
during these difficult times -- in terms of revenue growth and market share
gains in key segments. The important point is that we believe these trends will
continue to accelerate in our favor once the economy begins to improve.

So what does this all mean for the 4th quarter.

What I just told you about September can help set expectations for the 4th
quarter:

      o     We will benefit from the steady flow of revenue and profit from our
            annuity-like services, host-based software, maintenance, and
            financing.

      o     We expect our customers to continue to prioritize hardware and
            software decisions towards products that yield sure paybacks.

      o     In these decisions, we expect to benefit in three ways:

            1.    We now have product leadership over our piece-part
                  competitors.
            2.    Some of our competitors are going through significant changes,
                  brought on by increased competition in these difficult times.
                  Their business models are under pressure, so their product and
                  support levels may have to change.
            3.    And finally, we have leadership in helping customers build
                  total business solutions -- which means the decisions they
                  make with us today will fit into their business needs
                  tomorrow.

The 4th quarter will certainly be challenging.

      The current consensus is that we will grow Earnings Per Share by 50% over
      the 3rd quarter -- and deliver well over $2 billion in after-tax profit,
      at the same time that some of our competitors will lose money.

      It is extremely difficult to make predictions in this environment.
      However, based on everything we know today, we believe the current
      Earnings Per Share consensus for the 4th quarter is reasonable.

We'll address 2002 after our discussion of the 3rd quarter results, so let's get
started. Click on the NEXT button for Chart 4.
<Page>

RESULTS

Here's a financial overview of the 3rd quarter:

      o     I've mentioned that Revenue -- at $20.4 billion -- was down 3% at
            constant currency -- and 6%, as reported.

              Obviously, currency's impact was 3 points.

              Let me just note here that -- based on current spot rates -- the
              negative effect of currency on revenue for the 4th quarter would
              be only about one point -- so sequentially from the 3rd quarter
              we're going to get a little help.

      o     Pre-tax income was down 19% -- principally due to the slowing demand
            in our Technology OEM businesses that we discussed back in July, but
            also reflecting business impacts in September.

      o     Our tax rate was 29.5% -- down half a point from a year ago -- but
            the same as last quarter.

              Our year-to-date tax rate remains at 29.6%.

      o     Average diluted shares outstanding for the quarter were 1 billion,
            768 million -- down 2.3% from last year.

      o     And earnings per share were 90 cents -- down 18 cents or 17%.

                In these results we've absorbed currency, equity write-downs
                and workload-balancing initiatives. These three factors alone
                contributed about 13 cents to our year-to-year decline.

Now, let's turn to Revenue in the 3rd quarter -- starting with a geographic
perspective. Click the NEXT button for Chart 5.
<Page>

3Q01 GEOGRAPHIC REVENUE

Just over 90% of our revenue comes from sales to end-user customers, which we
break into three geographic areas.

      o     Constant currency is the best measure of comparative business
            growth.

      o     The Americas declined 5% at constant currency.

               As I've already mentioned, business in the U.S. had the greatest
               disruption in September.

      o     Europe grew 4% in constant currency, before a 3-point currency
            impact.

               Strong performance in Services and Software offset Hardware
               declines.

      o     Asia Pacific grew 5% in constant currency, before the 10 points of
            currency impact.

               The deceleration in Asia Pacific's growth from the 2nd quarter
               is mostly due to the decline in PC revenue as we shift away from
               the less profitable consumer sector.

Our OEM business -- the other 10% of our revenues -- declined 27% in the 3rd
quarter.

      We indicated in July that we expected a substantial decline in our
      Microelectronics business, based on the rapid deceleration in orders from
      our OEM customers that began in the 2nd quarter.

      And in our hard disk drive business, we experienced sustained weakness in
      demand, along with the rest of the industry, due to declining PC volumes.

Now, if you'll click on the NEXT button for Chart 6 -- I'll touch on Revenue by
major line item.
<Page>

3Q01 REVENUE

Let me start with Global Services, which at 41% of revenue is our largest
segment.

      Revenue was $8.7 billion -- growing 9% at constant currency.

      Services without Maintenance grew 11%.

Hardware revenue in the 3rd quarter was $7.5 billion -- an 18% decline at
constant currency.

      While we had strong growth in zSeries mainframes and Shark storage
      subsystems, our OEM businesses -- Microelectronics and hard disk drives
      -- as well as PC's -- faced even weaker markets than anticipated. Let me
      add that the falloff in PC revenue has little impact on our profit.

Software -- at $3.2 billion dollars -- had strong growth of 14% at constant
currency.

      We had terrific performance across all geographies and across all product
      lines.

      We gained share on key competitors -- even before the Informix acquisition
      -- with continued strong performance in our data base and WebSphere
      application server businesses.

Global Financing revenue -- at $822 million -- declined 2% at constant currency.

      Income-generating assets were flat from last year -- and financing
      originations were $8.8 billion in the quarter.

      But hardware remarketing was down in the quarter -- driven principally by
      a falloff in the U.S.

Now let's review gross profit margin -- Chart 7.
<Page>

3Q01 GROSS PROFIT MARGIN

Total gross profit margin for the 3rd quarter was 36.2% -- up 8 tenths of a
point from last year.

      Global Services gross profit margin improved nearly 2 points.

            We benefited from the cost-reduction actions in both Services and
            Maintenance, as well as from improved productivity in our
            outsourcing contracts.

      Hardware gross profit margin declined nearly 4 points.

            As expected, the key drivers were lower volumes in our technology
            group and pricing pressures in PCs and hard disk drives.

      Software gross profit margin improved 3 tenths of a point.

      And our Global Financing gross profit margin improved 9 points --
      reflecting lower funding rates and lower used hardware sales.

Now let's turn to Expense -- Chart 8.
<Page>

3Q01 EXPENSE SUMMARY CHART

Total expense was $5.1 billion -- up 5% from last year -- so that total
expense-to-revenue increased by two and a half points.

      However, both SG&A and R&D were flat year-to-year -- and down slightly
      from the 2nd quarter.

      Again, a major factor impacting total expense was a $156 million
      write-down of certain equity investments for other-than-temporary market
      declines.

While SG&A is flat, there are many changes under the surface -- and these will
continue.

      For example, at the beginning of the year, we targeted a $2 billion
      reduction in infrastructure expenses by the end of next year -- and we're
      already well on our way.

      As we reduce these expenses, we continue to increase investments in key
      areas where we can gain competitive advantage and prepare for 2002.

            For example, we spent more on direct sales, on technical sales
            support, on development, and, yes, on information technology.

            And we put it where we're gaining share -- Servers, Storage
            subsystems, Software, and Global Services.

      We're also using technology to improve our efficiency.

            IBM's e-Procurement is one of the largest private exchanges in the
            world -- purchasing 98% of its goods and services electronically.
            That's over $40 billion on an annualized rate.

            IBM.com and e-Care for customer support also continued to improve
            our productivity.

Now let's move to Cash Flow -- Chart 9.
<Page>

3Q01 - CASH FLOW

Cash generation for the 3rd quarter was solid -- with Free Cash Flow of $2
billion -- the same as last year. And we expect it to remain strong through the
rest of this year.

      Our ongoing focus on working capital management was a key contributor.

      Capital expenditures were up slightly year-to-year, with Services being a
      key driver.

Also in the third quarter --

      We spent $1.8 billion to repurchase about 18 million shares.

      This left us with $1.8 billion under our last Board authorization at the
      end of the 3rd quarter.

This continued strong cash flow -- even in a difficult economic environment --
gives us the flexibility to make necessary, appropriate investments for the
future of our business -- for internal growth, such as Outsourcing Services --
for acquisitions -- or for share repurchase.

Now let's look at the Balance Sheet, Chart 10.
<Page>

3Q01 - BALANCE SHEET

The balance sheet remains very healthy.

      Total debt decreased $800 million from the same time last year.

      Our $26.4 billion of Global Financing debt -- which was 92% of IBM's debt
      -- was leveraged at a comfortable 6.7 to 1.

      We increased our cash on hand, and we funded the Informix acquisition,
      while maintaining our core debt to capital at a very comfortable 11% --
      the same level as last year.

As I have said in previous quarters, this is not the environment to have growing
inventories or accounts receivable problems. Asset and debt levels continue to
receive high focus, and it shows in our results.

While for some companies, focus on the balance sheet and cash flow has now
become more fashionable, it has always been important to us -- and it pays in
many ways.

      Since 1994, we've put $50 billion of free cash flow to work -- after
      investing $38 billion in capital expenditures.

      Or consider that IBM reopened the investment-grade bond market in
      September with a heavily over-subscribed $1.5 billion bond issue.

Now let me turn to a discussion of some of our individual businesses -- starting
with Global Services -- Chart 11.
<Page>

GLOBAL SERVICES

Global Services -- at $8.7 billion -- was up 9% at constant currency.

      o     Services grew 11%, and
      o     Maintenance revenue was up 1%.

$10 billion of signings grew our backlog to $97 billion.

      We did have delays in September signings, particularly for Business
      Innovation Services in the Americas. But our Outsourcing Services pipeline
      going into the 4th quarter is as strong as we've ever seen.

      So, even in a challenging environment:

      o     we had seven deals greater than $100 million,
      o     our 6th straight quarter of signings at $10 billion or more,
      o     and nearly $600 million of web-hosting signings -- bringing our
            total web-hosting signings to $1.7 billion year-to-date.

Now let me review the three major services segments.

First, Outsourcing and e-Sourcing -- slightly more than 40% of Global Services
this quarter -- grew a healthy 13% at constant currency.

      o     New businesses like e-Sourcing -- IBM's web hosting, co-location and
            managed application hosting -- continued to drive revenue growth.
            e-Sourcing revenue was up 50% this quarter, and was nearly three
            quarters of a billion dollars year-to-date.

      o     And finally, leveraging the scale and scope of our outsourcing
            business, cost management initiatives drove another point of margin
            improvement this quarter, extending our lead against the
            competition.

Integrated Technology Services -- which includes product support services and
maintenance -- is about a third of Global Services.

      o     IT Services -- excluding maintenance -- was up 16%.
<Page>

      o     We continued to see strength across all geographies, driven by
            server and infrastructure consolidations.
      o     We also saw a slight up-tick in business continuity and recovery
            services this quarter, which grew 14%.

Next is Business Innovation Services, which includes consulting and systems
integration. It's slightly less than a quarter of Global Services revenue and
grew 6%.

      In the Americas, BIS revenue dropped off substantially, leading to a
      year-to-year decline in the geography. The events of September 11 further
      impacted an already weak consulting and integration environment.

      In Europe and Asia-Pacific, we had double-digit BIS growth.

      And worldwide, we continued to see good growth in key e-business areas:

            Supply chain revenue grew more than 50% worldwide -- and e-business
            integration revenue more than doubled.

Overall, this was a good quarter for Global Services.

      We have again gained share, because our services capabilities provide
      compelling value for our customers by helping them drive efficiencies in
      their IT infrastructures and processes. As a result:

            o     Outsourcing demand remains strong.
            o     Server consolidations are driving a healthy ITS business.
            o     And although Business Innovation Services in the U.S. has
                  weakened, many customers continue to integrate business
                  applications across their enterprises.

      Our opportunity pipeline going into the fourth quarter is as strong as
      we've ever seen, giving us good visibility that signings will again
      accelerate -- just as they did after Y2K.

Click on the NEXT button for Chart 12, and I'll discuss eServers and Storage
<Page>

eSERVERS AND STORAGE

Customers are shifting their priorities to high-end servers as they enhance
their infrastructure.

This strong momentum behind zSeries began a year ago and continued in the 3rd
quarter, with MIPS growth of more than 40%.

      Mainframe growth is driven by a number of factors. Customers are using
      mainframes --

      o     for consolidation, adopting Linux to centralize dispersed workloads
            like file, mail or print serving --
      o     for new workloads, like web and e-commerce enablement, and
      o     for greater reliability, security, workload management and reduced
            cost.

In the UNIX server market, almost every competitor has preannounced significant
revenue shortfalls, and we believe this market may be down as much as 35%. While
pSeries revenue was down 9%, we will again gain share.

      Earlier this month, right on schedule, IBM announced Regatta.

      This eServer p690 is the first product to use Power4 processors
      -- combining copper, silicon on insulator and low-k dielectric. These are
      the most advanced chips ever offered.

      But the p690 is more than just a hot chip. While the competition chooses
      to provide reliability through expensive redundant hardware, the p690 uses
      the mainframe's predictive technologies to keep applications up and
      running -- at far less cost to the customer.

      The advanced architecture of the p690 gives customers 25% better
      performance -- at half the price.

The iSeries -- our integrated server platform -- grew 10% this quarter, posting
gains in all geographies.

      In July, I told you about the release of the new operating system.
<Page>

      o     It allows customers to leverage multiple environments, including
            Java, WebSphere and Linux.

      o     We added dynamic partitioning capabilities to the iSeries.

      o     And this quarter, it won Best of Show at Linux World.

      Recent reports by IDC and the Gartner Group highlighted the iSeries' ease
      of use, low cost of ownership, 64-bit capability, and high reliability --
      all attributes that customers have exploited for server consolidation.

The Intel server market continues to be under intense pressure, and our xSeries
revenues were down 25% year-to-year, in line with the market.

      We recently announced an advanced set of technologies from our high-end
      servers, called Summit, which will bring best-of-breed availability,
      scalability and performance to the xSeries.

So, the real world is made up of multiple server platforms, and our customers
recognize IBM's unique ability to offer the best server to meet customers' many
different requirements.

Shark, our high-end disk storage device, grew 14% and continued to gain market
share.

      We've seen strong customer demand for native FICON which we announced this
      quarter -- and Shark remains the only Enterprise Storage device to offer
      this feature.

      We continue to see wide customer recognition of our competitive
      advantages. Just yesterday, Wal-Mart announced their decision to utilize
      z/900s and Shark storage as the backbone of their worldwide data center.

Complementing our disk solutions, we offer our customers low-cost,
high-performance tape storage. Tape continues to do well and grew by more than
20%.

Now click on the NEXT button for Personal Systems Chart 13.
<Page>

PERSONAL SYSTEMS

The PC industry slowdown and severe price pressures seen in the 1st half
-- intensified in the 3rd quarter.

            Our PC revenue was down 29% year to year.

            From the 2nd quarter, revenue was down 9% -- and we expect that,
            when all the data is in, this will be in line with industry trends.

      We are fine-tuning our business model and have taken aggressive actions to
      bring our structure in line with these revenue levels.

      o     Plant inventories have been reduced 25% this year, and channel
            inventories have been reduced 35%.

      o     Expenses have been reduced by leveraging the IBM.com sales channel.

      o     And earlier this month, we refreshed the entire product line --
            bringing new wireless, security and management capabilities to our
            ThinkPads and desktops.

Now if you'll move to Chart 14, we'll cover Technology.
<Page>

TECHNOLOGY

The semiconductor industry's severe downturn has led to competitors announcing
year-to-year revenue declines ranging from 20% to 50% -- and IBM
Microelectronics declined 30%. But we believe the 3rd and 4th quarter will be
the bottom.

While we are disappointed with these results, we recognize that, in any new
business, growth does not happen in a straight line -- as we found out in the
early years of Global Services.

But you know that technology has always been a key part of this industry -- and
as applications reach into new areas like pervasive computing and brand-new
customer sets, we fully expect technology to maintain this vital role. With our
leadership in custom logic -- leveraged by continued breakthroughs in IBM
Research and an expanding patent portfolio -- we will continue to make great
progress over the long term.

So, we'll leverage our leading-edge technologies based on copper, including
advances like SOI and low-k dielectric. For example, Regatta uses all of these,
and just last week we took it a step further with the announcement of ultra-low
power chips that can be exploited in portable devices.

And we are accelerating our use of these technologies, away from older
technologies, to meet our OEM customers' advancing requirements.

Like Global Services and Software, our Microelectronics business is an integral
part of our e-business strategy.

Before I move on, let me touch on the OEM hard disk drive. While we do expect to
gain share in both desktop and mobile drives in the 3rd quarter, our results
reflect the same issues of low volumes and price pressures as in the PC
industry.

Now click on the NEXT button for Software... Chart 15.
<Page>

SOFTWARE

Our software business -- at $3.2 billion -- was up 14% at constant currency.

      o     Operating System revenues, which make up about 20% of total
            software, were up 3% at constant currency, driven by server
            consolidation onto the z- and i-series platforms.

      o     Middleware, the majority of our software revenue at 80% of the
            total, grew 18%.

These results reflect broad-based success: across our portfolio -- across
operating platforms -- and across customer sets.

Across the portfolio:

      o     Our transaction-processing leadership continued as WebSphere revenue
            grew 75% and MQ Series revenue more than 100%.
      o     DB2 continued its success in the marketplace with 31% growth overall
            and an even higher 56% growth on UNIX and NT. And these numbers are
            without Informix.
      o     Tivoli turned the corner with continued sequential revenue growth
            and profitability improvements.
      o     And Lotus real-time collaboration software grew 18%.

We also had success across platforms:

      o     Our middleware software grew 32% on UNIX and NT.
      o     On host platforms, 14% middleware growth was led by our database
            tools business. We're aggressively going after this market, and
            should achieve about $400 million in revenue this year.

And we continue to have success across customer sets:

      o     We signed important new middleware deals with existing customers and
            new customers, like eBay which selected WebSphere as its technology
            foundation.
<Page>

As a result, we continue to gain share in key middleware sectors.

      o     BEA Systems, our largest competitor in application servers,
            reportedly expects flat to modest revenue growth this quarter,
            versus our 75% growth in WebSphere.

                  In September, GIGA projected that IBM WebSphere will more than
                  double its market share to 34%. They projected that BEA is
                  increasing share by only 5 points to 36%. We are now virtually
                  tied for the lead in this market, and expect to be number 1,
                  shortly.

      o     In database, Oracle had declining database revenues this quarter
            versus our 31% DB2 growth.

            And, our successful Informix database acquisition this quarter --

            o     more than doubled our distributed database revenue,
            o     Added 2500 skilled resources, and
            o     strengthened our presence in the small and midsize customer
                  segments with the addition of 100,000 customers.

      o     And in real-time web conferencing, Lotus Sametime leads with a 33%
            market share and almost three million corporate users, according to
            a July IDC study.

Finally, our ISV alliances continue to drive revenue growth. More than $1
billion of IBM revenue was generated this quarter by 70 global strategic
alliances. Our partnering strategy is paying off -- for our customers, our
software partners, and us.

We have talked to you a lot about IBM's unique ability to integrate
multi-platform e-business solutions for our customers. You can see this in our
Server results -- in our Services results -- and here in our Software results.

Now, if you'll hit the NEXT button, let me summarize my remarks.
<Page>

CLOSING REMARKS

Let me conclude by looking ahead to 2002.

In many respects this is an economic call -- when does worldwide GDP bottom out,
and what's the timing and strength of the recovery? But that's a call I'm going
to leave to you.

In a weak economy, our recent results have demonstrated our ability to sustain
strong profit. And, we will leverage our strengths and continue to invest for
the future. For example --

            o     We've recently acquired Informix, to double our revenue for
                  database software on distributed platforms -- and Mainspring,
                  to add their expertise to our consulting practices.

            o     And while we are carefully controlling our total expense, we
                  are also aggressively cutting infrastructure to enable
                  increased investments in areas that can directly drive growth.

When the economy picks up, the emerging changes in the competitive landscape
will accelerate. We've already seen evidence of that, even though some of our
piece-part competitors are hoping that history will repeat itself.

      o     We've been consistently gaining share on key piece-part competitors
            -- Sun, EMC, Oracle, BEA. Check out industry reports.

      o     Our sustained track record for new patents, our rollout of new
            technology, and our timely use of that technology in new products
            means that our leadership has been widening. Check out industry
            reports.

      o     Open standards have been gaining momentum. IDC reported that Linux
            was 27% of new operating system shipments -- last year -- even at
            this early stage in its capabilities. And they projected 24%
            compound growth over the next five years. That compares to 17% for
            Windows NT. IBM revamped its strategy around open standards because
            it's what our customers want. Our competitors have not, because it's
            not what our competitors want.
<Page>

      o     As customers get into the more sophisticated applications of
            e-business -- integration front to back -- they are turning to IBM
            because of our experience, because of our ability to provide
            business solutions, not just product solutions. Even some of our
            competitors are starting to recognize this and are trying to imitate
            us.

      o     IBM's business model has been building momentum over the past
            several years. Yet many of our competitors are facing major
            disruptions. They're reporting significant declines in revenue and,
            more importantly, profit declines -- if not operating losses -- as
            they adjust their structure to reflect the realities of competitive
            pricing.

These are all metrics that point to IBM as the emerging leader.

And we continue to expect long-term growth in IT spending. As worldwide GDP
growth settles out at 2 to 3 percent, many observers believe that IT spending
should grow around 10%.

      From an economic perspective -- information technology drives
      productivity, which drives earnings.

      Leading companies around the world understand the important shift that is
      taking place in our industry, as computers and telecommunications continue
      to converge -- tied together and supported by powerful servers,
      sophisticated middleware software, and global services integration
      capabilities.

That's exactly what our strategy has been built to address. Even during these
challenging times, it's given us a competitive advantage.

      And when the economy recovers, we expect to be in an even stronger
      competitive position -- and return to our model of high single-digit
      revenue growth and low double-digit growth in earnings per share.

In closing, IBM has managed through these tough times before. We benefit from
our experience.

      And we continue to feel good about our strategies, our products and our
      services, and the value we provide to our customers as the computing model
<Page>

      continues to shift in our direction. We're very encouraged about our
      prospects.
