Ariba® Spend Management solutions are easy to use, cost effective and quick to deploy, integrate with enterprise resource planning (ERP) and other software systems and can be used by companies of all sizes

executive offices are located at 807 11thAvenue, Sunnyvale, California 94089.

Recent Event

On September 20, 2007, we announced that we had signed a definitive agreement (the
Agreement) to acquire Procuri, Inc. (Procuri), a privately held company headquartered in Atlanta, Georgia. Procuri is a provider of on-demand supply management solutions. Under the terms of the Agreement, we will pay $93.0
million in consideration at closing, consisting of equal amounts of cash and stock, of which $14.0 million of the cash will be placed in escrow to secure indemnity obligations of Procuri stockholders. We will also assume and payoff approximately
$8.9 million of Procuris debt. The transaction is expected to close in the latter part of the first quarter of fiscal year 2008.

Industry
Background

In the last decade, technology-based solutions have emerged to help companies increase the efficiency of the procurement
process and more effectively manage their spend. These solutions allow organizations to automate critical tasks such as identifying global suppliers, sourcing goods and services, negotiating and managing contracts, processing invoices and payments
and managing trading relationships.

Procurement organizations were among the first to embrace spend management solutions as a way to
achieve corporate savings targets. Today, finance departments are leveraging them to drive improved cost management, business unit decision making and planning, budgeting and forecasting. Legal departments are implementing them to more effectively
author and manage contracts and IT departments are deploying them to enhance the value of existing systems and increase returns on investment.

The
Sourcing and Procurement Software Market

In its most recent Sourcing and Procurement Market Sizing Report, AMR Research, a
third-party research firm, estimated the size of the spend management software market at $2.4 billion for 2006 and projected that it will grow to be a $3.6 billion market by 2011. Further, it noted that the sourcing and procurement market (spend
management) grew at a rate of 10% per year from 2005 to 2006 and projected that the market will continue to grow at an 8% annual growth rate through 2011. The annual growth rate for alternative deployment models, which includes subscription
software, on-demand and software as a service (SaaS), is projected to grow at an annual growth rate of 19% through 2011. Actual annual growth rates may differ significantly from those forecast by AMR Research

Historically, our software was primarily provided as installed applications that were deployed behind a customers firewall. However, in response to customer demand, we have provided on-demand delivery of our software solutions, whereby
applications are hosted by Ariba or a third party, and customers access the solution via the Internet. Throughout fiscal year 2006 and 2007, we released new versions of our software designed to be more cost effective for an on-demand delivery model.
In addition, we plan to offer more of our software as part of bundled solutions that may include the combination of multiple modules as well as our professional services, such as purchasing best practices, commodity knowledge, knowledge transfer,
support and other procurement services. By combining software available as an installed application or as an on-demand service with global supplier access via the internet, professional services and spend management expertise into a comprehensive
solution, Ariba helps customers to address six key areas of spend management:

Frequently, suppliers join the Ariba Supplier Network at the request of buyers who purchase goods and services using Ariba Spend Management solutions. To help buyers attract and rapidly enable their target suppliers, Ariba has created Ariba
Supplier Enablement solutions that provide a broad range of products and services to enable suppliers of various sizes in all industries to join the Ariba Supplier Network. Ariba Supplier Enablement solutions include tools for content management,
order management, order fulfillment, invoicing and payment that help suppliers manage business transactions and content simply through a web browser or by using electronic methods (including XML and EDI). We have also created other Ariba Supplier
Programs, including Ariba Ready and Ariba Supplier Consulting, to help suppliers develop, deploy and promote their capabilities on the Ariba Supplier Network.

Access to the Ariba Supplier Network is provided in one of two ways: (1) through a direct access license to the Ariba Supplier Network itself whereby suppliers joining the Ariba Supplier Network must agree to a
standard web-based terms of use agreement with us, and link to the network through any of several formats (e.g., cXML, e-mail, EDI or fax) and (2) to buying organizations as part of their purchase of procurement software. Suppliers that exceed
certain transaction volumes are charged a fee for access to the Ariba Supplier Network. In addition, suppliers are charged fees for optional solutions such as data retention and technical support services.

Research and
Development

We introduced our initial product, Ariba Buyer, in June 1997, and since then have released a number of new products and
product enhancements to address the needs of sourcing and procurement professionals. We began to operate the Ariba Supplier Network in April 1999 and continue to provide enhancements to it on an ongoing basis. We introduced Ariba Sourcing in
September 2001, and upgraded the solution in September 2004 to incorporate functionality from legacy FreeMarkets, Inc. (FreeMarkets) applications. Over the past few years, we have introduced several new products, including Ariba Data
Enrichment (based on technology acquired from Softface, Inc. (Softface)) and several internally developed products such as Ariba Contract Workbench, Ariba Category Procurement and Ariba Invoice and Settlement. In addition to developing
new functionality, we have also been re-architecting our applications to be more easily deployed via an on-demand model. During fiscal years 2006 and 2007, we released, and continuing in fiscal year 2008 we plan to release, on-demand versions of
many of our software applications. If we are unable to develop new products or enhancements to existing products or corrections on a timely and cost-effective basis, particularly on-demand versions of our products, or if these new products or
enhancements do not have the features or quality measures to make them successful in the marketplace, our business will be harmed.

Our
research and development expenses were $51.2 million, $50.1 million and $49.6 million during the fiscal years ended September 30, 2007, 2006 and 2005, respectively. We also recorded amortization of acquired technology as part of cost of
revenues of $885,000, $2.6 million and $5.3 million during the fiscal years ended September 30, 2007, 2006 and 2005, respectively.

Our research and development organization is divided into teams focused on our various Ariba Spend Management solutions and the Ariba Supplier Network, as well as on server and infrastructure development, user interface and Internet
application design, tools development, enterprise integration, operations, quality assurance, documentation, release management and advanced development. These teams regularly share resources and collaborate on code development, quality assurance
and documentation.

International Operations

We sell our software and provide services and expertise worldwide. Our geographic coverage allows us to draw on business, technical and sourcing expertise from a worldwide workforce which provides stability to our operations and revenue
streams to leverage geography-specific economic trends.

We currently have offices in 21 countries. All of our international operations are
conducted through wholly-owned subsidiaries. Revenues from our international operations were $87.5 million, $90.3 million and $90.6 million for the fiscal years ended September 30, 2007, 2006 and 2005, respectively. See Note 8 of Notes to
Financial Statements for additional financial information about our geographic areas.

Competition

The market for spend management applications is highly competitive, rapidly evolving and fragmented and subject to changing technology and shifting
customer needs.

Our principal direct competition comes from ERP vendors whose software is installed by customers directly. We also compete
with specialty vendors that offer their software on a hosted basis or under a perpetual license. In our services business, we compete with several large and regional service providers. We anticipate additional competition from other established and
emerging companies as the spend management market continues to expand.

##### Table of Contents

Our current principal competitors include:



| |  |  | Enterprise software application vendors, including SAP AG and Oracle;
| | - |  | ---------------------------------------------------------------------



| |  |  | Smaller specialty vendors, including Emptoris, Verticalnet, Zycus and America Express S2S;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Smaller niche SaaS vendors, including Perfect Commerce, cc-Hubwoo, Ketera Technologies and Iasta; and
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | Service providers, including A.T. Kearney and McKinsey & Company.
| | - |  | -----------------------------------------------------------------

We believe the principal competitive factors considered with respect to, and the relative competitive standing of, our spend management software
solutions are:



| |  |  | Interoperability with existing commonly-used ERP systems;
| | - |  | ---------------------------------------------------------



| |  |  | Ease of use and rates of user adoption;
| | - |  | ---------------------------------------



| |  |  | Price and demonstrable cost-effective benefits for customers;
| | - |  | -------------------------------------------------------------



| |  |  | Performance, security, scalability, flexibility and reliability of the software;
| | - |  | --------------------------------------------------------------------------------



| |  |  | Vendor reputation and referenceable customers;
| | - |  | ----------------------------------------------



| |  |  | Quality of customer support; and
| | - |  | --------------------------------



| |  |  | Financial stability of the vendor.
| | - |  | ----------------------------------

Many of our current and potential competitors, such as ERP software vendors including Oracle and SAP, have longer operating histories, greater name recognition, larger marketing budgets and significantly greater resources, and a larger
installed base of customers than we do. They may be able to devote greater resources to the development, promotion and sale of their products than we can to ours, which can enable them to respond more quickly to new technology, introduce new spend
management modules and respond to changes in customer needs. In addition, many of our competitors have well-established relationships with our current and potential customers and have extensive knowledge of our industry. In the past, we have lost
potential customers to competitors for various reasons, including lower prices and other incentives not matched by us. Current and potential competitors have established or may establish cooperative relationships among themselves or with third
parties to increase the ability of their products to address customer needs and achieve greater market acceptance. The industry has experienced consolidation with both larger and smaller competitors acquiring companies to broaden their offerings or
increase scale. As a result, we may not be able to successfully compete against our current and future competitors.

Intellectual Property and Other
Proprietary Rights

We depend on our ability to develop and maintain the proprietary aspects of our technology. To protect our
proprietary technology, we rely primarily on a combination of contractual provisions, confidentiality procedures, trade secrets, and patent, copyright and trademark laws.

We license rather than sell our software products and require our customers to enter into license agreements, which impose restrictions on their ability to utilize the software. In addition, we seek to avoid
disclosure of our trade secrets through a number of means, including but not limited to requiring those persons with access to our proprietary information to execute confidentiality agreements with us and restricting access to our source code. We
seek to protect our software, documentation and other written and electronic materials under trade secret and copyright laws, which may afford only limited protection. We can make no assurance that any of our proprietary rights with respect to our
solutions will be viable or of value in the future since the validity, enforceability and type of protection of proprietary rights in these evolving technologies are uncertain and still evolving.

##### Table of Contents

We currently have 25 U.S. patents issued and 45 U.S. patent applications pending. We also have seven
foreign patents issued and ten foreign patent applications pending. It is possible that the patents that we have applied for, if issued, or our potential future patents may be successfully challenged or that no patents will be issued from our
pending patent applications. It is also possible that we may not develop proprietary products or technologies that are patentable, that any patent issued to us may not provide us with any competitive advantages, or that the patents of others will
harm our ability to do business.

We rely on technology that we license from third parties, including software that is integrated with
internally developed software and used in our software products to perform key functions. For example, we license integration software from TIBCO for Ariba Buyer. If we are unable to continue to license any of this software on commercially
reasonable terms, or at all, we will face delays in releases of our software until equivalent technology can be identified, licensed or developed, and integrated into our current product. These delays, if they occur, could materially and adversely
affect Ariba.

Ariba and the Ariba logo are registered trademarks in the United States. In addition, Ariba, the Ariba logo and the Ariba
boomerang design are registered in one or more foreign countries. The above-mentioned trademark applications are subject to review by the applicable governmental authorities, may be opposed by private parties, and may not issue.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and
use information that we regard as proprietary. Policing unauthorized use of our products is difficult, and while we are unable to determine the extent to which piracy of our software products exists, software piracy can be expected to be a
persistent problem. In addition, the laws of some foreign countries do not protect our proprietary rights to as great an extent as do the laws of the United States. Our means of protecting our proprietary rights may not be adequate and our
competitors may independently develop similar technology, duplicate our products or design around patents issued to us or our other intellectual property.

There has been a substantial amount of litigation in the software and Internet industries regarding intellectual property rights. For example, we have been sued for patent infringement by Sky Technologies, Inc.
(Sky). It is possible that in the future other third parties may claim that we or our current or potential future products infringe their intellectual property rights. We expect that software product developers and providers of
electronic commerce solutions will increasingly be subject to infringement claims as the number of products and competitors in our industry segment grows and the functionality of products in different industry segments overlaps. Any claims, with or
without merit, could be time-consuming, result in costly litigation, cause product shipment delays or require us to enter into royalty or licensing agreements. Royalty or licensing agreements, if required, may not be available on terms acceptable to
us or at all, which could harm our business. In addition, we may need to commence litigation or take other actions to protect our intellectual property rights which may be costly, time-consuming and distracting to management and would result in the
loss of our intellectual property. See Legal Proceedings and Note 6 of Notes to Consolidated Financial Statements.

|ITEM 1A. | RISK FACTORS
|-------- | ------------

Risk Factors

In addition to other information in this Form 10-K, the following risk factors should be carefully considered in evaluating Ariba and our business because
such factors may have a significant impact on our business, operating results and financial condition. As a result of the risk factors set forth below and elsewhere in this Form 10-K, actual results could differ materially from those projected
in any forward-looking statements.

We Compete in New and Rapidly Evolving Markets, and Our Spend Management Solutions Are At a
Relatively Early Stage of Development. These Factors Make Evaluation of Our Future Prospects Difficult.

Spend management software
applications and services are at a relatively early stage of development. For example, in September 2001, we introduced the majority of our initial Ariba Spend Management solutions and after our merger with FreeMarkets in 2004, we introduced several
new products and services integrating functionality acquired in the merger. We also introduced on-demand versions of a number of our software products throughout fiscal year 2006 and fiscal year 2007 and we plan to introduce additional on-demand
versions of our products in the future. These new and planned products may be more challenging to implement than our more established products, as we have less experience deploying these applications. The markets in which we compete are
characterized by rapid technological change, evolving customer needs and frequent introductions of new products and services. As we adjust to evolving customer requirements and competitive pressures, we may be required to further reposition our
product and service offerings and introduce new products and services. We may not be successful in developing and marketing such product and service offerings, or we may experience difficulties that could delay or prevent the development and
marketing of such product and service offerings, which could have a material adverse effect on our business, financial condition or results of operations.

Economic Conditions and Reduced Information Technology Spending May Adversely Impact Our Business.

Our business depends on the overall demand for enterprise software and services and on the economic health of our current and prospective customers. Weak economic conditions, or a reduction in information technology spending even with
healthy economic conditions, could adversely impact our business in a number of ways including longer sales cycles, lower average selling prices and reduced bookings and revenues.

Our Success Depends on Market Acceptance of Standalone Spend Management Solutions.

Our success depends on widespread customer acceptance of standalone spend management solutions from vendors like us, rather than solutions from ERP
software vendors and others that are part of a broader enterprise application solution. For example, ERP vendors, such as Oracle and SAP, could bundle spend management modules with their existing applications and offer these modules at little or no
cost. If our products and services do not achieve continued customer acceptance, our business will be seriously harmed.

We Have a
History of Losses and May Incur Significant Additional Losses in the Future.

We have a significant accumulated deficit as of
September 30, 2007, resulting in large part from cumulative charges for the amortization and impairment of goodwill and other intangible assets. We may incur significant losses in the future for a number of reasons, including those discussed in
other risk factors and the following:



| |  |  | adverse economic conditions;
| | - |  | ----------------------------



| |  |  | the failure of our standalone spend management solutions business to mature as a separate market category;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | declines in average selling prices of our products and services resulting from competition or the introduction of newer products that generally have lower list
prices than our more established products and other factors;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



14



---

##### Table of Contents

| |  |  | failure to successfully grow our sales channels;
| | - |  | ------------------------------------------------



| |  |  | increased reliance on on-demand delivery of software services that result in lower near-term revenues from customer deployments;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | failure to maintain control over costs;
| | - |  | ---------------------------------------



| |  |  | increased restructuring charges resulting from the failure to sublease excess facilities at anticipated levels and rates; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | charges incurred in connection with any future restructurings or acquisitions.
| | - |  | ------------------------------------------------------------------------------

Our Quarterly Operating Results Are Volatile, Difficult to Predict and May Be Unreliable as Indicators of Future Performance Trends.

Our quarterly operating results have varied significantly in the past and will likely continue to vary significantly in the future. As a result,
period-to-period comparisons of our results may not be meaningful and should not be relied upon as indicators of future performance. In addition, we may fail to achieve forecasts of quarterly and annual revenues and operating results.

Our quarterly operating results have varied or may vary depending on a number of factors, including the following:

Risks Related to Revenues:



| |  |  | fluctuations in demand, sales cycles and average selling price for our products and services;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | reductions in customers budgets for information technology purchases and delays in their purchasing cycles;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | fluctuations in the number of relatively larger orders for our products and services;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | increased dependence on relatively smaller orders from a larger number of customers;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | dependence on generating revenues from new revenue sources;
| | - |  | -----------------------------------------------------------



| |  |  | delays in recognizing revenue from multiple element arrangements;
| | - |  | -----------------------------------------------------------------



| |  |  | ability to renew ratable revenue streams, including subscription software, software maintenance and subscription services, without substantial declines from prior
arrangements,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in the mix of types of customer agreements and related timing of revenue recognition; and
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | changes in our product line such as our release of on-demand versions of our software products in fiscal year 2006 and fiscal year 2007 and our planned release of
additional on-demand versions in the future.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Risks Related to Expenses:



| |  |  | our overall ability to control costs, including managing reductions in expense levels through restructuring and severance payments;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | the level of expenditures relating to ongoing legal proceedings;
| | - |  | ----------------------------------------------------------------



| |  |  | costs associated with changes in our pricing policies and business model;
| | - |  | -------------------------------------------------------------------------



| |  |  | costs associated with the amortization of stock-based compensation expense; and
| | - |  | -------------------------------------------------------------------------------



| |  |  | the failure to adjust our workforce to changes in the level of our operations.
| | - |  | ------------------------------------------------------------------------------

Our On-Demand Strategy Carries a Number of Risks Which May Be Harmful to Our Business.

In November 2005, we announced a new strategy to offer on-demand versions of our software products. Our transition to an on-demand model entails both a
change to how we license products as well as how we deliver



15



---

##### Table of Contents

them. The license model change reflects a shift from perpetual license sales for our software in favor of purchasing the right to use the software for a
specified period of time through a subscription license. As customers increasingly move away from purchasing a perpetual license toward purchasing a subscription license, we may experience a deferral of revenues and cash payments from customers. In
addition to a change in license model, our transition to an on-demand model includes the release of multi-tenant versions of our software offerings. Multi-tenancy allows many customers to be supported on a single instance of a software
application.

Additional risks with the on-demand model include the following:



| |  |  | we may experience a delay in recognizing revenue due to the combination of multiple element arrangements and longer subscription terms;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | as a result of increased demands on our engineering organization to develop multi-tenant versions of our products while supporting and enhancing our existing
products, we may not introduce multi-tenant versions of our products or enhancements to our products on a timely and cost-effective basis or at appropriate quality levels;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may fail to achieve our targeted pricing;
| | - |  | --------------------------------------------



| |  |  | we expect to experience a decrease in the demand for our implementation services to the extent fewer customers license our software products as installed
applications;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may not successfully achieve market penetration in our newly targeted markets, including target customers we characterize as middle-market companies;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may have a short-term and/or long-term decrease in total revenues as a result of the transition; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | we may incur costs at a higher than forecasted rate as we expand our on-demand operations.
| | - |  | ------------------------------------------------------------------------------------------

Our Business Could Be Seriously Harmed If We Fail to Retain Our Key Personnel.

Our future performance depends on the continued service of our senior management, product development and sales personnel. The loss of the services of one
or more of these personnel could seriously harm our business. Our ability to retain key employees may be harder given that we have substantial operations in several geographic regions, including Sunnyvale, California, Pittsburgh, Pennsylvania and
Bangalore, India. In addition, uncertainty created by turnover of key employees could result in reduced confidence in our financial performance which could cause fluctuations in our stock price and result in further turnover of our employees.

Our Revenues In Any Quarter May Fluctuate Significantly Because Our Sales Cycles Can Be Long and Unpredictable.

Our sales cycles can be long and unpredictable. The purchase of our products is often discretionary and generally involves a significant commitment of
capital and other resources by a customer. It frequently takes several months to finalize a sale and requires approval at a number of management levels within the customer organization. The implementation and deployment of our products requires a
significant commitment of resources by our customers and third parties and/or professional services organizations. As a result of the length and unpredictability of our sales cycle, our revenues in any quarter may fluctuate significantly.

Revenues in Any Quarter May Vary to the Extent Recognition of Revenue Is Deferred When Contracts Are Signed. As a Result, Revenues in
Any Quarter May Be Difficult to Predict and Are an Unreliable Indicator of Future Performance Trends.

We frequently enter into
contracts where we recognize only a portion of the total revenue under the contract in the quarter in which we enter into the contract. For example, we may recognize revenue on a ratable basis over the life of the contract or enter into contracts
where the recognition of revenue is conditioned upon delivery of



16



---

##### Table of Contents

future product or service elements. The portion of revenues recognized on a deferred basis may vary significantly in any given quarter, and revenues in any
given quarter are a function both of contracts signed in such quarter and contracts signed in prior quarters.

Revenues From Our Ariba
Sourcing Solution Could Be Negatively Affected If Customers Elect to Purchase Our Self-Service Products Rather Than Our Technology-Enhanced Services.

Revenue from our full-service sourcing services offering has been declining as existing customers renew contracts for lower volumes and/or purchase our lower-priced self-service technologies (such as Ariba Sourcing
On-Demand). We have several large multi-year contracts for these technology-enhanced services, some of which will come up for renewal during fiscal year 2008 and beyond. If these customers do not renew their contracts upon expiration, or if they
elect to use one of our lower-cost self-service solutions, our future revenues may decrease.

A Decline in Revenues May Have a
Disproportionate Impact on Operating Results and Require Further Reductions in Our Operating Expense Levels.

Because our expense levels
are relatively fixed in the near term and are based in part on expectations of our future revenues, any decline in our revenues to a level that is below our expectations would have a disproportionately adverse impact on our operating results for
that quarter.

We Are Subject to Evolving and Expensive Corporate Governance Regulations and Requirements. Our Failure to Adequately
Adhere to These Requirements or the Failure or Circumvention of Our Controls and Procedures Could Seriously Harm Our Business and Results of Operations.

Because we are a publicly-traded company, we are subject to certain federal, state and other rules and regulations, including those required by the Sarbanes-Oxley Act of 2002. Compliance with these evolving
regulations is costly and requires a significant diversion of management time and attention, particularly with regard to our disclosure controls and procedures and our internal control over financial reporting. Although we have reviewed our
disclosure and internal controls and procedures in order to determine whether they are effective, our controls and procedures may not be able to prevent fraud or other errors in the future. Faulty judgments, simple errors or mistakes, or the failure
of our personnel to adhere to established controls and procedures may make it impossible for us to ensure that the objectives of the control system are met. A failure of our controls and procedures to detect fraud or other errors could seriously
harm our business and results of operations.

We Sometimes Experience Long Implementation Cycles, Which May Increase Our Operating Costs
and Delay Recognition of Revenues.

Many of our products are complex applications that are generally deployed with many users.
Implementation of these applications by enterprises is complex, time consuming and expensive. Long implementation cycles may delay the recognition of revenue as some of our customers engage us to perform system implementation services, which can
defer revenue recognition for the related software license revenue. In addition, when we experience long implementation cycles, we may incur costs at a higher level than anticipated, which may reduce the anticipated profitability of a given
implementation.

If a Sufficient Number of Suppliers Do Not Join and Maintain Their Participation In the Ariba Supplier Network,
It May Not Attract a Sufficient Number of Buyers and Other Sellers Required to Make the Network Successful.

In order to provide buyers
on the Ariba Supplier Network an organized method for accessing goods and services, we rely on suppliers to maintain web-based product catalogs, indexing services and other content



17

##### Table of Contents

aggregation tools. Any failure of suppliers to join the Ariba Supplier Network in sufficient numbers, or of existing suppliers to maintain their
participation in the Ariba Supplier Network, would make the network less attractive to buyers and consequently other suppliers. Our inability to access and index these catalogs and services provided by suppliers would result in our customers having
fewer products and services available to them through our solutions, which would adversely affect the perceived usefulness of the Ariba Supplier Network.

We Could Be Subject to Potential Claims Related to Our On-Demand Solutions, As Well As the Ariba Supplier Network.

We warrant to our customers that our on-demand solutions and the Ariba Supplier Network will achieve specified performance levels to allow our customers to conduct their transactions. To the extent we fail to meet
warranted performance levels, we could be obligated to provide refunds or credits for future use or maintenance. Further, to the extent that a customer incurs significant financial hardship due to the failure of our on-demand solutions or the Ariba
Supplier Network to perform as specified, we could be exposed to additional liability claims.

Failure to Establish and Maintain
Strategic Relationships with Third Parties Could Seriously Harm Our Business, Results of Operations and Financial Condition.

We have
established strategic relationships with a number of other companies. These companies are entitled to resell our products, to host our products for their customers, and/or to implement our products within their customers organizations. We
cannot be assured that any existing or future resellers or hosting or implementation partners will perform to our expectations. For example, in the past we have not realized the anticipated benefits from strategic relationships with a number of
resellers. If our current or future strategic partners do not perform to expectations, or if they experience financial difficulties that impair their operating capabilities, our business, operating results and financial condition could be seriously
harmed.

We Face Intense Competition. If We Are Unable to Compete Successfully, Our Business Will Be Seriously Harmed.

The market for our solutions is intensely competitive, evolving and subject to rapid technological change. This competition could result in further
price pressure, reduced profit margins and loss of market share, any one of which could seriously harm our business. Competitors vary in size and in the scope and breadth of the products and services they offer. We compete with several major
enterprise software companies, including SAP and Oracle. We also compete with several service providers, including McKinsey & Company and A.T. Kearney. In addition, we compete with smaller specialty vendors or smaller niche providers of
sourcing or procurement products and services, including Emptoris, Zycus, America Express S2S, Perfect Commerce, cc-Hubwoo, Ketera Technologies and Iasta. Because spend management is a relatively new software category, we expect additional
competition from other established and emerging companies if this market continues to develop and expand. For example, third parties that currently help implement Ariba Buyer and our other products could begin to market products and services that
compete with our products and services. These third parties, which include IBM, Accenture, Capgemini, Deloitte Consulting, BearingPoint and Unisys, are generally not subject to confidentiality or non-compete agreements that restrict such competitive
behavior.

Many of our current and potential competitors, such as ERP software vendors including Oracle and SAP, have longer operating
histories, significantly greater financial, technical, marketing and other resources, significantly greater name recognition and a larger installed base of customers than us. These vendors could also introduce spend management solutions that are
included as part of broader enterprise application solutions at little or no cost. In addition, many of our competitors have well-established relationships with our current and potential customers and have extensive knowledge of our industry. In the
past, we have lost potential customers to competitors for various reasons, including lower prices and incentives not matched by us. In addition, current



18



---

##### Table of Contents

and potential competitors have established or may establish cooperative relationships among themselves or with third parties to increase the ability of their
products to address customer needs. Accordingly, it is possible that new competitors or alliances among competitors may emerge and rapidly increase their market share. We also expect that competition will increase as a result of industry
consolidations. The industry has experienced consolidation with both larger and smaller competitors acquiring companies to broaden their offerings or increase scale. As a result, we may not be able to successfully compete against our current and
future competitors.

Our Pending Acquisition and Any Future Acquisitions Will Be Subject to a Number of Risks.

Our pending acquisition of Procuri and any future acquisitions will be subject to a number of risks, including:



| |  |  | the diversion of management time and resources;
| | - |  | -----------------------------------------------



| |  |  | the difficulty of assimilating the operations and personnel of the acquired companies;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | the potential disruption of our ongoing business;
| | - |  | -------------------------------------------------



| |  |  | the difficulty of incorporating acquired technology and rights into our products and services;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | unanticipated expenses related to integration of the acquired companies;
| | - |  | ------------------------------------------------------------------------



| |  |  | difficulties in implementing and maintaining uniform standards, controls, procedures and policies;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | the impairment of relationships with employees and customers as a result of any integration of new management personnel;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | potential unknown liabilities associated with acquired businesses; and
| | - |  | ----------------------------------------------------------------------



| |  |  | impairment of goodwill and other assets acquired.
| | - |  | -------------------------------------------------

The Benefits We Anticipate From Acquiring Procuri May Not Be Realized.

We entered into an agreement
to acquire Procuri with the expectation that the acquisition will result in various benefits including, among other things, accelerating our penetration into the mid-market segment, enhancing our customer base and recognizing efficiencies. We may
not realize any of these benefits or may not realize them as rapidly, or to the extent, anticipated by our management and certain financial or industry analysts. Procuris contribution to our financial results may not meet the current
expectations of our management for a number of reasons, including integration risks, and could dilute our profits beyond the current expectations of our management. Potential liabilities assumed in connection with our acquisition of Procuri also
could have an adverse effect on our business, financial condition and operating results. If these risks materialize, our stock price could be materially adversely affected.

Although we currently expect to close the Procuri acquisition late in the first quarter of fiscal year 2008, our acquisition of Procuri is subject to a
number of closing conditions, including regulatory approvals. If these closing conditions are not met, we may not be able to complete our acquisition of Procuri.

If We Fail to Develop Products and Services on a Timely and Cost-Effective Basis, or If Our Products or Services Contain Defects, Our Business Could Be Seriously Harmed.

In developing new products and services, we may:



| |  |  | fail to develop, introduce and market products in a timely or cost-effective manner;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | find that our products and services are obsolete, noncompetitive or have shorter life cycles than expected;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | fail to develop new products and services that adequately meet customer requirements or achieve market acceptance; or
| | - |  | ---------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | develop products that contain undetected errors or failures when first introduced or as new versions are released.
| | - |  | ------------------------------------------------------------------------------------------------------------------

If new releases of our products or potential new products are delayed, we could experience a delay or loss of revenues and customer dissatisfaction.

Pending Litigation Could Seriously Harm Our Business.

There can be no assurance that existing or future litigation will not have a material adverse effect on our business, financial position, results of operations or cash flows, or that the amount of any accrued losses
is sufficient for any actual losses that may be incurred. See Note 6 of Notes to Consolidated Financial Statements.

We May Incur
Additional Restructuring Charges that Adversely Affect Our Operating Results.

We have recorded significant restructuring charges in the
past relating to the abandonment of numerous leased facilities, including most notably portions of our Sunnyvale, California headquarters. Moreover, we have from time to time revised our assumptions and expectations regarding lease abandonment
costs, resulting in additional charges.

We review these estimates each reporting period, and to the extent that our assumptions change,
the ultimate restructuring expenses for these abandoned facilities could vary significantly from current estimates. For example, a reduction in assumed market lease rates of $0.25 per square foot per month for the remaining term of the leases, with
all other assumptions remaining the same, would increase the estimated lease abandonment loss on the vacated portions of our Sunnyvale, California headquarters by $3.1 million as of September 30, 2007. Additional lease abandonment costs,
resulting from the abandonment of additional facilities or changes in estimates and expectations about facilities already abandoned, could adversely affect our operating results.

We May Incur Additional Goodwill Impairment Charges that Adversely Affect Our Operating Results.

We review goodwill for impairment annually and more frequently if events and circumstances indicate that the asset may be impaired and that the carrying
value may not be recoverable. Factors we consider important that could trigger an impairment review include, but are not limited to, significant underperformance relative to historical or projected future operating results, significant changes in
the manner of use of the acquired assets or the strategy for our overall business, significant negative industry or economic trends, a significant decline in our stock price for a sustained period, and decreases in our market capitalization below
the recorded amount of our net assets for a sustained period. Our stock price is highly volatile and has experienced significant declines in the past. The balance of goodwill is $326.1 million as of September 30, 2007 and, there can be no
assurance that future goodwill impairments will not occur.

Our Stock Price Is Highly Volatile and the Market Price of Our Common Stock
May Decrease in the Future.

Our stock price has fluctuated dramatically. There is a significant risk that the market price of our
common stock will decrease in the future in response to any of the following factors, some of which are beyond our control:



| |  |  | variations in our quarterly operating results;
| | - |  | ----------------------------------------------



| |  |  | announcements that our revenues or income are below analysts expectations;
| | - |  | ---------------------------------------------------------------------------



| |  |  | changes in analysts estimates of our performance or industry performance;
| | - |  | --------------------------------------------------------------------------



| |  |  | general economic slowdowns;
| | - |  | ---------------------------



| |  |  | changes in market valuations of similar companies;
| | - |  | --------------------------------------------------



| |  |  | sales of large blocks of our common stock;
| | - |  | ------------------------------------------

##### Table of Contents

| |  |  | announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures or capital commitments;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the loss of a major customer or our failure to complete significant license transactions; and
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | additions or departures of key personnel.
| | - |  | -----------------------------------------

We Are at Risk of Further Securities Class Action Litigation Due to Our Stock Price Volatility.

In the past, securities
class action litigation has often been brought against companies following periods of volatility in the market price of their securities. We have experienced significant volatility in the price of our stock over the past two years. We may in the
future be the target of similar litigation. Securities litigation could result in substantial costs and divert managements attention and resources, which could seriously harm our business.

If the Protection of Our Intellectual Property Is Inadequate, Our Competitors May Gain Access to Our Technology, and We May Lose Customers.

We depend on our ability to develop and maintain the proprietary rights of our technology. To protect our proprietary technology, we
rely primarily on a combination of contractual provisions, including customer licenses that restrict use of our products, confidentiality agreements and procedures, and patent, copyright, trademark and trade secret laws. We have 25 patents issued in
the United States, but may not develop other proprietary products that are patentable. Despite our efforts, we may not be able to adequately protect our proprietary rights, and our competitors may independently develop similar technology, duplicate
our products or design around any patents issued to us. This is particularly true because some foreign laws do not protect proprietary rights to the same extent as those of the United States and, in the case of our solutions, because the validity,
enforceability and type of protection of proprietary rights in these technologies are uncertain and evolving. If we fail to adequately protect our proprietary rights, we may lose customers.

There has been a substantial amount of litigation in the software industry and the Internet industry regarding intellectual property rights. For example,
in fiscal year 2005 we paid $37.0 million to ePlus to settle a lawsuit alleging that three of our products, Ariba Buyer, Ariba Marketplace and Ariba Category Procurement, infringed patents held by a third party. In addition, we have been sued by Sky
for alleged patent infringement. See LitigationPatent Litigation in Note 6 of Notes to Consolidated Financial Statements. It is possible that in the future, other third parties may claim that we or our current or potential future
products infringe their intellectual property rights. We expect that software product developers and providers of electronic commerce solutions will increasingly be subject to infringement claims, and third parties may claim that we or our current
or potential future products infringe their intellectual property. Any claims, with or without merit, could be time-consuming, result in costly litigation, cause product shipment delays or require us to enter into royalty or licensing agreements.
Royalty or licensing agreements, if required, may not be available on terms acceptable to us or at all, which could seriously harm our business.

We must now, and may in the future have to, license or otherwise obtain access to intellectual property of third parties. For example, we are currently dependent on developers licenses from ERP, database, human resource and other
systems software vendors in order to ensure compliance of our products with their management systems. In addition, we rely on technology that we license from third parties, including software that is integrated with internally developed software and
used in our software products to perform key functions. For example, we license integration software from TIBCO for Ariba Buyer. If we are unable to continue to license any of this software on commercially reasonable terms, or at all, we will face
delays in releases of our software until equivalent technology can be identified, licensed or developed, and integrated into our current products. These delays, if they occur, could materially adversely affect our business.

In addition, we may need to commence litigation or take other actions to protect our intellectual property rights. For example, in April 2007, we
filed a lawsuit against Emptoris, Inc. for patent infringement in the United States District Court for the Eastern District of Texas. This lawsuit and other potential litigation and actions



21



---

##### Table of Contents

brought by us could be costly, time-consuming and distracting to management and could result in the impairment or loss of portions of our intellectual
property. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attaching the validity and enforceability of our intellectual property rights.

Our Business Is Susceptible to Numerous Risks Associated with International Operations.

International operations have represented a significant portion of our revenues over the past three years. We have committed and expect to continue to
commit significant resources to our international sales and marketing activities. We are subject to a number of risks associated with these activities. These risks generally include:



| |  |  | currency exchange rate fluctuations;
| | - |  | ------------------------------------



| |  |  | unexpected changes in regulatory requirements;
| | - |  | ----------------------------------------------



| |  |  | tariffs, export controls and other trade barriers;
| | - |  | --------------------------------------------------



| |  |  | longer accounts receivable payment cycles and difficulties in collecting accounts receivable;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | difficulties in managing and staffing international operations;
| | - |  | ---------------------------------------------------------------



| |  |  | potentially adverse foreign tax consequences, including withholding in connection with the repatriation of earnings;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | the burdens of complying with a wide variety of foreign laws; and
| | - |  | -----------------------------------------------------------------



| |  |  | political instability.
| | - |  | ----------------------

For
international sales and expenditures denominated in foreign currencies, we are subject to risks associated with currency fluctuations. We hedge risks associated with foreign currency transactions in order to minimize the impact of changes in foreign
currency exchange rates on earnings. We utilize forward contracts to hedge trade and intercompany receivables and payables. There can be no assurance that our hedging strategy will be successful or that currency exchange rate fluctuations will not
have a material adverse effect on our operating results.

Anti-takeover Provisions in Our Charter Documents and Delaware Law Could
Discourage, Delay or Prevent a Change in Control of Our Company and May Affect the Trading Price of Our Common Stock.

Certain
anti-takeover provisions in our certificate of incorporation and bylaws and certain provisions of Delaware law may have the effect of delaying, deferring or preventing a change in control of the Company without further action by our stockholders,
may discourage bids for our common stock at a premium over the market price of our common stock and may adversely affect the market price of our common stock and other rights of our stockholders.

business.



|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

Litigation

IPO Class Action Litigation

In 2001,
a number of purported shareholder class action complaints related to our and FreeMarkets initial public offerings (the IPOs) were filed in the United States District Court for the Southern District of New York against us and
FreeMarkets, and against certain of the two companies former officers and directors. These complaints were later consolidated into single class action proceedings related to each IPO. In June 2003, a proposed settlement was reached between
plaintiffs and us and FreeMarkets (the individual defendants having been previously dismissed). The Company merged with FreeMarkets in July 2004. In June 2005, the underwriters filed an appeal of the District Courts order granting class
certification in six focus cases. On December 5, 2006, the Court of Appeals issued an opinion, reversing the District Courts order granting class certification and finding that plaintiffs cannot satisfy certain elements required for class
actions. On June 25, 2007, in light of the Court of Appeals decision, the District Court entered an order terminating the proposed settlement based on a stipulation among the parties to the settlement. On August 14, 2007, the
plaintiffs filed amended complaints in the focus cases, seeking to address the deficiencies raised in the Court of Appeals opinion. On September 27, 2007, plaintiffs moved to certify the classes in those focus cases. The parties are
currently discussing further discovery that the plaintiffs seek from the underwriters and the issuers. As of September 30, 2007, no amount is accrued as a loss is not considered probable or estimable.

Litigation Relating to Alleged Patent Infringement Disclosures Involving the Companys Chairman and Chief Executive Officer and Former President
and Director

On October 31, 2005, a purported class action, alleging violations of Sections 10(b) and 20(a) of the Exchange Act
was filed in the United States District Court for the Eastern District of Virginia against our Chairman and Chief Executive Officer and a former president and director of ours. That case was transferred to the United States District Court for the
Northern District of California and an Amended Complaint was filed on November 30, 2006, adding us as a defendant. The action is brought on behalf of stockholders who purchased our stock from June 10, 2003 to February 7, 2005. A
second amended complaint was filed on May 18, 2007. It alleges that the defendants artificially inflated our stock price between those dates by failing to disclose, in public statements that we made about our products, market position and
performance, that some of those products allegedly infringed patents belonging to a third party. The defendants have filed a motion to dismiss plaintiffs second amended complaint. The motion was heard by the Court on October 22,
2007. As of September 30, 2007, no amount is accrued as a loss is not considered probable or estimable.

Patent Litigation

In October 2006, after an unsuccessful attempt to resolve the matter by negotiation, we were sued by Sky for patent infringement in the
United States District Court for the District of Massachusetts. The complaint (which has



23



---

##### Table of Contents

been amended twice to add additional patents) does not specify which products are accused or what damages are claimed. Sky has served subsequent
pleadings in the case contending that the Ariba Dynamic Trade and Ariba Sourcing software products (whether hosted by Ariba for specific customers or distributed to customers for installation at their sites), as well as certain other Ariba software
products when used together with Ariba Sourcing software, infringe certain claims of two of the U.S. patents owned by Sky. Sky seeks economic relief in the form of a royalty on Ariba's sale of the accused products, other Ariba software
products, and sourcing services, enhancement of damages, an attorneys fee award and an injunction against further infringement. The total amount of the royalty now claimed by Sky before interest, enhancement or attorneys fees is approximately
$30.8 million. Sky previously sought to add additional claims under a certificate of correction for the third patent in suit, but on June 7, 2007, the Court denied its request to amend its pleading. Sky might seek to add
those claims or other claims under other patents against Ariba in a different proceeding in the future. On October 30, 2007, the Court denied motions for summary judgment which had been filed by Ariba. The case has been set for trial commencing
on December 3, 2007. As of September 30, 2007, no amount is accrued as a loss is not considered probable or estimable. In addition, Sky has filed a separate patent infringement action in the United States District Court for the Eastern
District of Texas against Procuri (see Note 13 of Notes to Consolidated Financial Statements).

General

Defending against these actions and various other claims and legal actions arising in the ordinary course of business may require significant management
time and, regardless of the outcome, result in significant legal expenses. If our defenses are unsuccessful or if we are unable to settle on favorable terms, we could be liable for a large damages award and, in the case of patent litigation, subject
to an injunction that could seriously harm its business and results of operations.

We received an insurance reimbursement of $4.9 million
in March 2006 for expenses incurred in certain prior litigation matters. The amount was recorded as a credit to sales and marketing expense in the year ended September 30, 2006, which is where the incurred expenses were initially recorded.

We also received $1.6 million, which is net of taxes of approximately $300,000, in the year ended September 30, 2006 related to the
settlement of a legal matter assumed in the merger with FreeMarkets. The amount was recorded as a credit to interest and other income, net in the year ended September 30, 2006.

Indemnification

We sell software
licenses, access to our on-demand offerings and/or services to our customers under contracts that we refer to as Terms of Purchase or Software License and Service Agreements (collectively, SLSA). Each SLSA contains the relevant terms of
the contractual arrangement with the customer, and generally includes certain provisions for indemnifying the customer against losses, expenses and liabilities from damages that may be incurred by or awarded against the customer in the event our
software or services are found to infringe upon a patent, copyright, trade secret, trademark or other proprietary right of a third party. The SLSA generally limits the scope of remedies for such indemnification obligations in a variety of
industry-standard respects, including but not limited to certain product usage limitations and geography-based scope limitations, and a right to replace an infringing product or service or modify them to make them non-infringing. If we cannot
address the infringement by replacing the product or service, or modifying the product or service, we are allowed to cancel the license or service and return certain of the fees paid by the customer.

To date, we have not had to reimburse any of our customers for any losses related to these indemnification provisions and no material customer claims for
such indemnification are outstanding as of September 30, 2007.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following discussion contains forward-looking statements, including, without limitation, our expectations regarding our outlook and future revenues.
Our actual results may differ significantly from those projected in the forward-looking statements. Factors that might cause future actual results to differ materially from our recent results or those projected in the forward-looking statements
include, but are not limited to, those discussed in the section entitled Risk Factors and in Outlook for Fiscal Year 2008 in this section. Except as required by law, we assume no obligation to update the forward-looking
statements or our risk factors for any reason.

Recent Event

On September 20, 2007, we announced that we had signed an Agreement to acquire Procuri, a privately held company headquartered in Atlanta, Georgia. Procuri is a provider of on-demand supply management solutions.
Under the terms of the Agreement, we will pay $93.0 million in consideration at closing, consisting of equal amounts of cash and stock, of which $14.0 million of the cash will be placed in escrow to secure indemnity obligations of Procuri
stockholders. We will also assume and payoff approximately $8.9 million of Procuris debt. The transaction is expected to close in the latter part of the first quarter of fiscal year 2008.

Prior Period Adjustment

In connection with a review
of our deferred revenue accounts in the year ended September 30, 2007, a $19.1 million adjustment was made to increase the September 30, 2006 deferred revenue, current and decrease deferred revenue, less current portion. The adjustment of
deferred revenues corrected an error in the classification between deferred revenue, current and deferred revenues, less current portion. Total deferred revenues were not impacted by the adjustment. See also Notes 1 and 14 of Notes to Consolidated
Financial Statements.

Business Model

Ariba Spend Management solutions are delivered in a flexible manner, depending upon the needs and preferences of the customer. For customers seeking self sufficiency, we offer flexible, highly configurable and
easy-to-use technology and related services that can be deployed behind the firewall or delivered as an on-demand service. For customers seeking expert assistance, we offer sourcing process and commodity expertise in over 400 categories of spend.

We have aligned our business model with the way we believe customers want to purchase and deploy spend management solutions. Customers may
generally subscribe to our software products and services for a specified term, purchase a perpetual software license and/or pay for services on a time-and-materials basis, depending upon their business requirements. Our revenue is comprised of
license fees, subscription and maintenance fees, and services and other fees. License revenue mainly consists of fees charged for the use of our software products under perpetual agreements. Subscription and maintenance revenue consists of fees
charged for hosted on-demand software solutions and fees for product updates and support, as well as fees paid by suppliers for access to the Ariba Supplier Network. Services and other revenue consists of fees for implementation services, consulting
services, managed services, training, education, premium support and other miscellaneous items, which are more fully described in BusinessAriba Spend Management Expertise.

Due to the different treatment of our revenue streams under applicable accounting guidance, each type of revenue has a different impact on our
consolidated financial statements. Subscription fees for hosted on-demand software solutions are generally fixed for a specific period of time, and revenue is recognized ratably over the term. Therefore, a subscription license will result in
significantly lower current-period revenue than an equal-sized perpetual license, but with revenue recognized in future periods. Similarly, maintenance fees are generally fixed for a specific period of time, and revenue is recognized ratably over
the maintenance term. Maintenance contracts are typically entered into when new software licenses are purchased, at a percentage of the software license fee. In addition, most of our customers renew their maintenance contracts annually to continue
receiving product updates and product support. Given the ratable revenue recognition and historically high renewal rates of our subscription and maintenance agreements, this revenue stream has generally been more stable over time than perpetual
software license fees. Services revenues are driven by a contract, project or statement of work, in which the fees may be fixed for specific services to be provided over time or billed on a time and materials basis. The majority of our license fees
are from perpetual software license sales. Revenue from these license sales is often recognized in the quarter that the software is delivered. Individual software license sales can be significant (greater than $1.0 million) and sales cycles are
often lengthy and difficult to predict. As such, the timing of a few large software license transactions or the recognition of license revenue from these transactions can substantially affect our quarterly operating results.

These different revenue streams also carry different gross margins. Revenue from license fees tends to be high-margin revenue, and gross margins are
often greater than 85%. Revenue from subscription and maintenance fees tends to be higher-margin revenue with gross margins typically around 75% to 80%. Subscription and maintenance fees are generally based on software products developed by us,
which carry minimal marginal cost to reproduce and sell. Revenue from labor-intensive services and other fees tends to be lower-margin revenue, with gross margins typically in the 20% to 35% range. Our overall gross margins could fluctuate from
period to period depending upon the mix of revenue. For example, a period with a higher mix of license revenue versus services revenue would drive overall gross margin higher and vice versa.

Overview of Fiscal Year 2007

Our software sales have
shifted over time from predominantly perpetual licenses, with upfront revenue recognition, to more subscription or term licenses, with revenue recognition spread out over time. This trend contributed to our subscription revenues increasing and our
license revenue declining in the year ended September 30, 2007. Our backlog of subscription software contracts increased during the year, which we anticipate will be recognized as revenue during fiscal year 2008 and beyond.

More specifically, license revenues of $18.2 million in the year ended September 30, 2007 were down
24% compared to the year ended September 30, 2006, while subscription and maintenance revenues of $140.6 million were up 11% compared to the year ended September 30, 2006. These changes were primarily due to a shift from perpetual software
licenses to more subscription sales, as well as growth in overall software sales. Finally, services and other revenues of $142.8 million were down 2% compared to the year ended September 30, 2006.

As a result of these trends, we experienced a continued shift in our revenue mix, with license revenues contributing 6% of total revenues in the year
ended September 30, 2007 compared to 8% in the year ended September 30, 2006, subscription and maintenance revenues contributing 47% of total revenues in the year ended September 30, 2007 compared to 43% in the year ended
September 30, 2006, and services and other revenues contributing 47% of total revenues in the year ended September 30, 2007 compared to 49% in the year ended September 30, 2006. Our gross profit as a percentage of revenues improved to
46% in the year ended September 30, 2007 compared to 41% in the year ended September 30, 2006, primarily as a result of the improvement in gross margin from services and other revenues from 11% in the year ended September 30, 2006 to
21% in the year ended September 30, 2007 and due to the shift in our revenue mix (as the gross margin of software subscription and maintenance revenues is typically much higher than the gross margin of services revenues).

Operating expenses decreased to $167.6 million in the year ended September 30, 2007 compared to $178.9 million in the year ended September 30,
2006. The decrease in operating expenses is primarily attributable to a decrease in net restructuring costs of $30.5 million from the $26.3 million charge in the year ended September 30, 2006 to a $4.2 million benefit recorded in the year ended
September 30, 2007 resulting from our execution of a sublease agreement in June 2007 and revisions of our estimates in the Northern California real estate market in fiscal years 2007 and 2006. The decrease in operating expenses is also
attributed to an overall $8.8 million decrease in stock-based compensation ($6.6 million of the overall decrease is within operating expenses) primarily due to a change in the terms of the employee stock purchase plan in August 2006. These decreases
in operating expenses were partially offset by a $6.6 million or 9% increase in compensation and benefits expense associated with an 11% increase in average sales and marketing, research and development and general and administrative headcount in
supporting our transition to an on-demand model, an increase in sales commission due to reversals of $5.5 million in the year ended September 30, 2006 based on the expiration of statute of limitations (see Note 6 of Notes to Consolidated
Financial Statements), a $4.9 million insurance reimbursement in the year ended September 30, 2006 related to litigation expenses, and an increase in intellectual property related legal expenses of $5.3 million. In sum, our total net expenses,
including cost of revenue and other items, decreased to $316.6 million compared to $343.8 million in the year ended September 30, 2006, which caused a net loss for the year of $15.0 million compared to $47.8 million in the year ended
September 30, 2006.

Outlook for Fiscal Year 2008

With our increased backlog, introduction of new offerings and continued shift in demand toward subscription sales, we expect continued growth in subscription revenue in fiscal year 2008 as compared to fiscal year
2007.

We believe that our success for fiscal year 2008 will depend largely on our ability to: (1) manage the continuing shift to an
on-demand delivery model from both a product and a financial standpoint; (2) sell bundled solution offerings that include both technology and expert services; (3) renew our subscription or time-based revenues, including on-demand software
fees, maintenance fees, and fees for certain services; (4) capitalize on new revenue opportunities, such as fees for the Ariba Supplier Network and selling on-demand spend management solutions to smaller and mid-market customers; and
(5) complete our pending acquisition of Procuri and effectively manage the integration of its operations with our business.

We
believe that key risks to our revenues in fiscal year 2008 include: our ability to introduce additional on-demand versions of our products in fiscal year 2008; our ability to renew ratable revenue streams without substantial declines from prior
arrangements, including subscription software, software maintenance and

subscription services; the impact of transitioning managed procurement customers to subscription software customers; our ability to generate organic growth;
our deferral of services revenues as a result of including software implementation and other services as part of a sale with our subscription software solutions; the market acceptance of spend management solutions as a standalone market category;
the overall level of information technology spending; our ability to close and recognize benefits from the Procuri acquisition; and potential declines in average selling prices. We believe that key risks to our future operating profitability
include: our ability to maintain or grow our revenues; our ability to maintain adequate utilization of our services organization; our ability to renew sublease agreements and find new tenants for abandoned space; and the potential adverse impacts
resulting from legal proceedings. Our prospects must be considered in light of the risks encountered by companies at a relatively early stage of development, particularly given that we operate in new and rapidly evolving markets and face an
uncertain economic environment. We may not be successful in addressing such risks and difficulties. See Risk Factors for additional information.

Comparison of the Fiscal Years Ended September 30, 2007, 2006 and 2005

Revenues

Please refer to Note
1 of Notes to Consolidated Financial Statements and Application of Critical Accounting Policies and Estimates below for a description of our accounting policy related to revenue recognition.

License

License revenues for the
year ended September 30, 2007 were $18.2 million, a 24% decrease from license revenues of $23.9 million for the year ended September 30, 2006. This decrease is primarily attributable to a shift from perpetual license sales to more
subscription sales. In the future, we believe that license revenues will continue to decline. See Outlook for Fiscal Year 2008. Prospectively, commencing in fiscal year 2008, we will present license revenues within services and other
revenues.

License revenues for the year ended September 30, 2006 were $23.9 million, a 50% decrease from license revenues of $47.8
million for the year ended September 30, 2005. This decrease is primarily attributable to a shift from perpetual license sales to more subscription sales and the difficult selling environment for enterprise software applications in the year
ended September 30, 2006.

We generally ship our software products shortly after entering into a license contract. However, product
shipment may be delayed for a number of factors, including factors within our discretion. For example, delivery dates may be affected by the number of software license orders shipped or received in the quarter, the degree to which software license
orders are concentrated at the end of the quarter, and our operational ability to fulfill software license orders at the end of the quarter. Any delay in shipping software products may have the effect of reducing revenue in the current period and
increasing revenue in future periods.

Subscription and maintenance

Subscription and maintenance revenues for the year ended September 30, 2007 were $140.6 million, an 11% increase from subscription and maintenance
revenues of $126.6 million for the year ended September 30, 2006. Subscription revenues consist mainly of fees for software access subscription and hosted software services. Subscription revenues for the year ended September 30, 2007 were
$65.9 million compared to $51.8 million for the year ended September 30, 2006. The increase of $14.1 million, or 27%, was primarily due to growth in overall software bookings, a shift from perpetual license sales to more subscription sales
and the growth of Ariba Supplier Network revenue. Maintenance revenues consist primarily of Ariba Buyer and Ariba Sourcing product maintenance fees. Maintenance revenues for the year ended September 30, 2007 were $74.7 million compared to
$74.8 million for the year ended September 30, 2006. Although license revenues decreased 24% during the same period, maintenance renewal revenue on our installed base remains relatively consistent. We anticipate that subscription revenues will
increase in fiscal year 2008 compared to fiscal year 2007, partially offset by modest declines of maintenance revenues in fiscal year 2008.

Subscription and maintenance revenues for the year ended September 30, 2006 were $126.6 million, a 3% increase from subscription and maintenance revenues of $123.4 million for the year ended September 30, 2005. Subscription
revenues for the year ended September 30, 2006 were $51.8 million compared to $47.3 million for the year ended September 30, 2005. The increase of $4.5 million, or 10%, was primarily due to a shift from perpetual license sales to more
subscription sales and the growth of Ariba Supplier Network revenue. Maintenance revenues for the year ended September 30, 2006 were $74.8 million compared to $76.1 million for the year ended September 30, 2005. The decrease of
$1.3 million, or 2%, was primarily due to decreased maintenance renewal revenue. Although license revenues decreased 50% during the same period, maintenance renewal revenue on our installed base remains relatively consistent.

Services and other

Services and other revenues were $142.8 million for the year ended September 30, 2007, a 2% decrease from services and other revenues of $145.5 million for the year ended September 30, 2006. The decrease of
$2.6 million in services and other revenues is primarily due to a decline in renewals of Sourcing services revenues in the year ended September 30, 2007 and a slight increase in the deferral of consulting services revenues in the year ended
September 30, 2007 due to such services being bundled with other products or services without evidence of fair value. We anticipate that services and other revenues will decline in fiscal year 2008 compared to fiscal year 2007 due to the
transition of managed procurement customers to subscription software customers.

Services and other revenues were $145.5 million for the
year ended September 30, 2006, a 4% decrease from services and other revenues of $151.8 million for the year ended September 30, 2005. The decrease of $6.3 million in services and other revenues is primarily due to the deferral of
approximately $3.1 million of consulting services revenues in the year ended September 30, 2006 due to such services being bundled with other products or services without evidence of fair value, and due to a decline in implementation revenues.

Cost of Revenues

License

Cost of license revenues consists of product, delivery and royalty costs. Cost of license revenues for the year
ended September 30, 2007 was $1.7 million, a 15% decrease from cost of license revenues of $2.0 million for the year ended September 30, 2006. The decrease was primarily due to a decrease in royalty costs associated with the 24%
decrease in license revenues.

Cost of license revenues for the year ended September 30, 2006 was $2.0 million, a 44% decrease
from cost of license revenues of $3.6 million for the year ended September 30, 2005. The decrease of $1.6 million was primarily due to a decrease in royalty costs associated with the 50% decrease in license revenues and a decrease in warranty
expense of $391,000 primarily due to a warranty provision recorded in the year ended September 30, 2005.

Subscription and
maintenance

Cost of subscription and maintenance revenues consists of labor costs for implementation and services, including
stock-based compensation costs, hosting services, technical support, training personnel, facilities and equipment costs. Cost of subscription and maintenance revenues for the year ended September 30, 2007 was $32.7 million, a 21% increase from
cost of subscription and maintenance revenues of $27.0 million for the year ended September 30, 2006. This increase is primarily the result of an increase in hosted support costs associated with the overall 27% increase in subscription revenues
in the year ended September 30, 2007. We anticipate that cost of subscription and maintenance expenses will remain relatively consistent as a percentage of revenues in the year ending September 30, 2008 compared to the year ended
September 30, 2007.

Cost of subscription and maintenance revenues for the year ended September 30, 2006 was $27.0 million, a 2%
decrease from cost of subscription and maintenance revenues of $27.6 million for the year ended September 30, 2005. This decrease is primarily due to a $1.6 million decrease in cost of maintenance revenues due to a slight decline in average
support headcount, partially offset by an increase in stock-based compensation expense of $1.4 million primarily due to restricted stock grants in fiscal year 2006 and the stock option exchange program completed in the fourth quarter of fiscal year
2005.

Services and other

Cost of services and other revenues consists of labor costs for consulting services, including stock-based compensation costs, training personnel, facilities and equipment costs. Cost of services and other revenues was

$112.9 million for the year ended September 30, 2007, a 13% decrease from cost of services and other revenues of $129.6 million for the year ended
September 30, 2006. This decrease of $16.6 million is primarily due to the following: (1) decreased compensation and benefits expense and travel expense of $3.9 million and $2.2 million, respectively, due to a slight decrease in average
headcount resulting from our re-allocation of services personnel to sales efforts in fiscal year 2007 in managing our transition to an on-demand model; (2) decreased overhead costs of $5.2 million associated with the slight decrease in average
headcount; (3) decreased stock-based compensation of $2.2 million primarily due to a change in the terms of the employee stock purchase plan in August 2006 whereby the option component of the plan was eliminated (see Note 1 of Notes to
Consolidated Financial Statements) and a decrease in stock-based compensation expense related to restricted stock grants; and (4) decreased temporary and contract labor costs of $1.7 million primarily due to cost cutting efforts initiated in
fiscal year 2007. We anticipate that cost of services and other revenues will decline as a percentage of revenues in the year ending September 30, 2008 compared to the year ended September 30, 2007 due to continued operational improvements
in consulting and managed services.

Cost of services and other revenues was $129.6 million for the year ended September 30, 2006, a
3% increase from cost of services and other revenues of $125.2 million for the year ended September 30, 2005. This increase is primarily the result of an increase in stock-based compensation expense of $5.7 million, primarily due to restricted
stock grants in fiscal year 2006 and the stock option exchange program completed in the fourth quarter of fiscal year 2005. This was partially offset by a slight decrease in depreciation expense, primarily due to office and computer equipment
reaching their respective maximum depreciable lives and a change in the estimated useful life of computer equipment in the year ended September 30, 2006 (see Note 1 of Notes to Consolidated Financial Statements).

Amortization of acquired technology and customer intangible assets

Amortization of acquired technology and customer intangible assets represents the amortization of assets associated with our fiscal year 2004 business combinations with Softface and FreeMarkets. This expense amounted
to $14.1 million, $15.7 million and $19.5 million for the years ended September 30, 2007, 2006 and 2005, respectively, and primarily relates to our 2004 merger with FreeMarkets. The decreases in the years ended September 30, 2007 and 2006
are primarily attributable to assets reaching the end of their estimated useful lives.

Gross profit

Our gross profit as a percentage of revenues for the year ended September 30, 2007 was 46% compared to 41% for the year ended September 30,
2006. The increase in gross profit as a percentage of revenues was primarily due to an increase in services and other gross profit as a percentage of services and other revenues and due to the shift in our revenue mix (as the gross margin of
software subscription and maintenance revenues is typically much higher than the gross margin of services revenues). Our gross profit of services and other as a percentage of services and other revenues for the year ended September 30, 2007 was
21% compared to 11% for the year ended September 30, 2006, primarily due to operational improvement in consulting and managed services.

Our gross profit as a percentage of revenues for the year ended September 30, 2006 was 41% compared to 46% for the year ended September 30, 2005. The decline in gross profit as a percentage of revenues was primarily due to a
decrease in services and other gross profit as a percentage of services and other revenues. Our gross profit of services and other as a percentage of services and other revenues for the year ended September 30, 2006 was 11% compared to 18% for
the year ended September 30, 2005.

Operating Expenses

Sales and marketing

Sales and
marketing expenses include costs associated with our sales and marketing personnel and product marketing personnel and consist primarily of compensation and benefits, commissions and bonuses, stock-based

compensation costs, promotional and advertising expenses, travel and entertainment expenses related to these personnel and the provision for doubtful
accounts. Sales and marketing expenses for the year ended September 30, 2007 were $93.9 million, a 14% increase from sales and marketing expenses of $82.5 million for the year ended September 30, 2006. This increase of $11.4 million is
primarily due to the following: (1) increased compensation and benefits expense of $6.2 million associated with an 18% increase in average sales and marketing headcount in supporting our transition to an on-demand model; (2) increased
sales commissions of $5.9 million primarily associated with reversals of sales commission of $5.5 million in the year ended September 30, 2006 (see Note 6 of Notes to Consolidated Financial Statements); and (3) a $4.9 million insurance
reimbursement in the year ended September 30, 2006 related to litigation expenses which had previously been charged to sales and marketing. These increases were partially offset by a decrease in stock-based compensation expense of $3.6 million
primarily due to a change in the terms of the employee stock purchase plan in August 2006 whereby the option component of the plan was eliminated (see Note 1 of Notes to Consolidated Financial Statements) and a decrease in stock-based compensation
expense related to restricted stock grants. We anticipate that sales and marketing expenses will remain relatively consistent as a percentage of revenues in the year ending September 30, 2008 compared to the year ended September 30, 2007.

Sales and marketing expenses for the year ended September 30, 2006 were $82.5 million, a 13% decrease from sales and marketing
expenses of $94.3 million for the year ended September 30, 2005. This decrease is primarily due to the following: (1) a $4.9 million insurance reimbursement in the year ended September 30, 2006 related to litigation expenses which had
previously been charged to sales and marketing; (2) decreased legal expenses of $3.7 million resulting from litigation settled in fiscal year 2005; (3) decreased sales commissions of $3.3 million primarily due to a 6% decrease in average
sales and marketing personnel and due to an increase in reversals of sales commission accruals (see Note 6 of Notes to Consolidated Financial Statements); (4) decreased bad debt expense of $3.5 million due to improvements in cash collections in
the year ended September 30, 2006 and a change in estimate for calculation of the allowance for doubtful accounts, which reduced the allowance for doubtful accounts by approximately $480,000 in the year ended September 30, 2006; and
(5) decreased marketing and advertising expenses of $2.3 million due to cost cutting measures initiated in fiscal year 2005. These decreases were partially offset by an increase in stock-based compensation expense of $4.7 million primarily due
to restricted stock grants in fiscal year 2006 and the stock option exchange program completed in the fourth quarter of fiscal year 2005.

Research and development

Research and development expenses include costs associated with the development of new products,
enhancements of existing products for which technological feasibility has not been achieved, and quality assurance activities, and primarily included compensation and benefits, stock-based compensation costs, consulting costs and the cost of
software development tools and equipment. Research and development expenses for the year ended September 30, 2007 were $51.2 million, a 2% increase from research and development expenses of $50.1 million for the year ended
September 30, 2006. The increase of $1.1 million is primarily due to an increase in compensation and benefits expense of $1.6 million or 7% due to an 8% increase in average headcount and a $739,000 increase in consulting expense related to the
continued development of our on-demand solutions in fiscal year 2007. These increases were partially offset by a decrease in stock-based compensation expense of $1.5 million primarily due to a change in the terms of the employee stock purchase plan
in August 2006 whereby the option component of the plan was eliminated (see Note 1 of Notes to Consolidated Financial Statements) and a decrease in stock-based compensation expense related to restricted stock grants. We anticipate that research and
development expenses will slightly decline as a percentage of revenues in the year ending September 30, 2008 compared to the year ended September 30, 2007.

Research and development expenses for the year ended September 30, 2006 were $50.1 million, a 1% increase from research and development expenses of $49.6 million for the year ended September 30, 2005.
The increase is primarily due an increase in stock-based compensation expense of $4.3 million primarily due to restricted stock grants in fiscal year 2006 and the stock option exchange program completed in the fourth quarter of fiscal year

2005. The increase was partially offset by a decrease in compensation and benefits of $3.3 million resulting from a 4% decrease in average research and
development headcount and a slight decrease in depreciation expense primarily due to office and computer equipment reaching their respective maximum depreciable lives and a change in the estimated useful life of computer equipment in the year ended
September 30, 2006.

General and administrative

General and administrative expenses include costs for executive, finance, human resources, information technology, legal and administrative support functions, and primarily include compensation and benefits,
stock-based compensation costs and professional services costs. General and administrative expenses for the year ended September 30, 2007 were $39.8 million, a 21% increase from general and administrative expenses of $32.9 million for the
year ended September 30, 2006. This increase of $6.9 million is primarily due to the following: (1) an increase in intellectual property related legal expenses of $5.3 million associated with legal expenses related to patent infringement
matters; and (2) increased overhead and salaries expense of $1.1 million and $1.0 million, respectively, associated with an 8% increase in average general and administrative headcount in supporting the transition to an on-demand model. These
increases were partially offset by a decrease in stock-based compensation expense of $1.3 million primarily due to a change in the terms of the employee stock purchase plan in August 2006 whereby the option component of the plan was eliminated (see
Note 1 of Notes to Consolidated Financial Statements) and a decrease in stock-based compensation expense related to restricted stock grants. We anticipate that general and administrative expenses will decline as a percentage of revenues in the year
ending September 30, 2008 compared to the year ended September 30, 2007 due to reduced legal expenses.

General and
administrative expenses for the year ended September 30, 2006 were $32.9 million, a 5% decrease from general and administrative expenses of $34.7 million for the year ended September 30, 2005. This decrease is primarily due to
(1) a decrease in legal expenses of $5.0 million related to a patent infringement matter settled in February 2005; (2) a decrease in compensation and benefits of $1.9 million primarily due to a decrease in severance payouts associated with
terminated employees in the year ended September 30, 2005; and (3) a decrease in depreciation expense of $1.6 million primarily due to office and computer equipment reaching their respective maximum depreciable lives, a change in the
estimated useful life of computer equipment in the year ended September 30, 2006 and an adjustment to depreciation expense of $455,000 related to a prior period. We assessed our findings with respect to the prior period item using the guidance
of SAB 99, and concluded that the amount of the error was immaterial to fiscal year 2006 and the prior period. These decreases were partially offset by an increase in stock-based compensation expense of $5.5 million due to restricted stock grants in
fiscal year 2006 and the stock option exchange program completed in the fourth quarter of fiscal year 2005 and an increase of $710,000 related to a property tax audit assessment on facilities in California related to calendar years 2001 through
2004. See Note 6 of Notes to Consolidated Financial Statements for further discussion.

Other incomeSoftbank

During the years ended September 30, 2007, 2006 and 2005, we recorded $13.6 million, $13.6 million and $9.5 million, respectively, of income from the
settlement with Softbank entered into in October 2004. The $37.0 million of deferred income recorded upon the settlement with Softbank is being recognized into income, starting in January 2005, over the remaining term of the three-year license that
ended in October 2007. For further discussion, see Note 12 of Notes to Consolidated Financial Statements. We anticipate that other incomeSoftbank in the year ending September 30, 2008 will be approximately $566,000.

Amortization of other intangible assets

Amortization of other intangible assets was $525,000, $800,000 and $798,000 in the years ended September 30, 2007, 2006 and 2005, respectively. These amounts consisted of the amortization of trade name/trademark and order backlog
resulting from our merger with FreeMarkets and our acquisitions of Softface and Alliente. The decrease in the year ended September 30, 2007 is primarily attributable to assets reaching the end of their estimated useful lives.

Restructuring and integration costs

For the year ended September 30, 2007, we recorded a net benefit to operations of $4.2 million. In June 2007, we entered into an amendment with
Juniper Networks, Inc. (Juniper), the successor in interest to NetScreen Technologies, Inc. (NetScreen) to the sublease dated as of October 18, 2002 between Ariba and NetScreen. Pursuant to the amendment, Juniper agreed
to renew its sublease of approximately 177,000 square feet of space at our Sunnyvale, California headquarters through January 2013. In addition, Juniper agreed, effective October 10, 2007, to lease approximately 89,000 square feet of
additional space at our Sunnyvale, California headquarters through January 2013. Our Chief Executive Officer, Robert Calderoni, is also on the Board of Directors of Juniper and he abstained from voting on Aribas Board of Directors
approval of the lease agreement. Also in June 2007, we revised our estimates for rental rate projections and sub-lease commencement dates to reflect current market conditions primarily in the Northern California real estate market. The impact of the
execution of the sublease agreement with Juniper was a benefit to operations of approximately $7.4 million and the impact of the revised estimated rental rate projections and sub-lease commencement dates was a charge to operations of $3.2 million,
resulting in a net benefit to operations of $4.2 million in the year ended September 30, 2007.

For the year ended September 30,
2006, we recorded a charge to operations of $26.3 million for restructuring and integration costs, which is comprised of the following: (1) in June 2006, we revised our estimates for rental rate projections to reflect current market conditions
primarily in the Northern California real estate market and sublease commencement dates, resulting in a charge of $24.4 million; (2) severance and related benefits of $273,000 resulting from our goal to better align expenses with our revenue
levels and to enable us to invest in certain strategic growth; (3) property taxes of $942,000 related to abandoned facilities in California based on a property tax audit assessment related to calendar years 2001 through 2004 (see Note 6 of
Notes to Consolidated Financial Statements); and (4) an adjustment to our restructuring obligation of $730,000 related to a prior period. We assessed our findings with respect to the prior period item using the guidance of SAB 99, and
concluded that the amount of the error was immaterial to fiscal year 2006 and the prior period.

For the year ended September 30,
2005, we recorded a charge to operations of $41.2 million for restructuring and integration costs, which is comprised of the following: (1) in June 2005, we revised our estimates for sublease rental projections resulting in a charge of $31.8
million; (2) severance and related benefits of $3.8 million resulting from our goal to better align expenses with our revenue levels and to enable us to invest in certain strategic growth initiatives; (3) severance and related benefits of
$1.6 million for terminated employees and legal and consulting costs of $1.3 million in connection with the merger with FreeMarkets in order to improve our post-merger competitiveness and productivity; (4) a $1.6 million adjustment to our
restructuring obligation in March 2005 that was related to a prior period (based on the guidance in SAB 99, we concluded that the amount of the prior period error was immaterial to fiscal years 2005 and 2004); and (5) in July 2005, we
reassessed our office space in Pittsburgh, Pennsylvania and ceased use of one of the floors we lease through 2010, which resulted in a charge of $1.2 million.

Goodwill impairment

In accordance with SFAS No. 142, Goodwill and Other Intangible
Assets, we perform a test for impairment on an annual basis or as events and circumstances indicate that goodwill or other intangible assets may be impaired and that the carrying values may not be recoverable. We perform our annual assessment
for impairment in the fourth quarter of each fiscal year. In June 2005, based on a combination of factors, particularly: (1) our market capitalization at that time; (2) our then current and projected operating results; (3) significant
trends in the enterprise software industry; and (4) our decision to reduce our workforce and eliminate excess facility space, we concluded there were sufficient indicators to require us to assess whether any portion of our recorded goodwill
balance was impaired. We determined that our estimated fair value was less than the recorded amount of our net assets, thereby necessitating that we assess our recorded goodwill for impairment. As required by SFAS No. 142, in measuring the
amount of goodwill impairment, we made a hypothetical allocation of the estimated fair value



39

##### Table of Contents

of the Company to the tangible and intangible assets (other than goodwill) and liabilities. Based on this allocation, we concluded that goodwill was impaired
in the amount of $247.8 million. We performed the annual assessment in the fourth quarter of fiscal years 2007, 2006 and 2005, and no further indication of goodwill impairment was noted.

Litigation provision

We recorded a
$37.0 million provision related to the settlement of our patent infringement litigation during the year ended September 30, 2005.

Interest and other income, net

Interest and other income, net for the year ended September 30, 2007 was $14.3 million,
an increase of $3.4 million from interest and other income, net of $10.9 million for the year ended September 30, 2006. The increase is primarily attributable to the following: (1) an increase in interest income of $2.6 million due to an
overall increase in the rate of return on marketable investments and an increase in average cash and marketable securities balances in fiscal year 2007; (2) a net realized gain of $2.2 million associated with the repatriation of cash from Ariba
Korea, Ltd. (Ariba Korea) and the substantial liquidation of the entity in the year ended September 30, 2007; (3) an increase in foreign currency transaction gains in the amount of $1.3 million on accounts receivable billed
from Ariba, Inc. in foreign currencies to customers headquartered in foreign countries due to the U.S. dollar weakening against the Euro and British Pound; and (4) a net realized gain associated with currency translation adjustments of $425,000
due to the substantial liquidation of FreeMarkets s.a./n.v., the former FreeMarkets entity in Belgium, in the year ended September 30, 2007. These amounts were partially offset by a gain of $1.9 million in the year ended September 30, 2006
related to the settlement of a legal matter assumed in the merger with FreeMarkets and the release of a tax reserve of $800,000 in the year ended September 30, 2006.

Interest and other income, net for the year ended September 30, 2006 was $10.9 million, an increase of $5.1 million from interest and other income, net of $5.9 million for the year ended September 30, 2005.
The increase is primarily attributable to the following: (1) an increase in interest income of $3.5 million due to an overall increase in the rate of return on marketable investments; (2) a gain of $1.9 million in the year ended
September 30, 2006 related to the settlement of a legal matter assumed in the merger with FreeMarkets; (3) the release of a tax reserve of $800,000 in the year ended September 30, 2006; (4) a $445,000 payroll tax refund in the
year ended September 30, 2006 related to a former FreeMarkets subsidiary; (5) a realized gain of approximately $300,000 in the year ended September 30, 2006 on an investment in a public company; and (6) realized losses of
approximately $400,000 in the year ended September 30, 2005 on sales of marketable investments. These amounts were partially offset by a realized net gain on a Japanese Yen cash flow hedge in the amount of $2.3 million in the year ended
September 30, 2005.

Provision for income taxes

We recorded income tax provisions of $1.9 million, $1.5 million and $6.6 million for the years ended September 30, 2007, 2006 and 2005, respectively. The increase in the year ended September 30, 2007 is
primarily attributable to an increase in withholding taxes associated with the repatriation of cash from Ariba Korea in the year ended September 30, 2007. The decrease in the year ended September 30, 2006 is primarily attributable to the
$4.8 million tax effect related to the buy-out of the minority interests from Softbank in October 2004 and $554,000 recorded for the repatriation of cash from Ariba Korea in the year ended September 30, 2005, partially offset by a slight
increase in foreign income taxes.

Utilization of our net operating loss and tax credit carryforwards may be subject to a substantial
annual limitation due to the ownership change limitations imposed by Internal Revenue Code Section 382 and similar state provisions. Such an annual limitation could result in the expiration of our federal and state net operating loss and tax
credit carryforwards before utilization.



40

##### Table of Contents

As of September 30, 2007, we had net operating loss carryforwards for federal, state and foreign tax
purposes of approximately $1.4 billion, $760.0 million and $4.2 million, respectively, before consideration of any annual limitations as described above. The federal, state and foreign net operating loss carryforwards expire in various years from
fiscal year 2010 through fiscal year 2027, from fiscal year 2008 through fiscal year 2027 and from fiscal year 2010 through fiscal year 2013, respectively. As of September 30, 2007, we had research credit carryforwards for federal and state tax
purposes of approximately $39.0 million and $25.1 million, respectively. If not utilized, the federal research credit carryforwards will expire in various years from fiscal year 2010 through fiscal year 2023. The state research credit carryforwards
will continue indefinitely, except for approximately $244,000, which will expire in fiscal year 2018. We also had manufacturers credit carryforwards as of September 30, 2007 for state tax purposes of approximately $2.0 million, which will
expire in various years from fiscal year 2008 through fiscal year 2012. Our net operating loss and tax credit carryforwards include net operating loss and research credit carryforwards of approximately $250.3 million and $5.1 million, respectively,
generated by FreeMarkets, which are subject to annual limitations which could reduce or defer the utilization of those losses and credits.

Minority interests

In December 2000, our consolidated subsidiary, Nihon Ariba K.K. (Nihon Ariba), sold
approximately 41% of its common stock for cash consideration of $40.0 million to Softbank pursuant to our strategic relationship with Softbank. In April 2001, Nihon Ariba sold an additional 2% of its common stock for cash consideration of $4.0
million to third parties. Also in April 2001, our consolidated subsidiary, Ariba Korea, sold approximately 42% of its common stock for cash consideration of $8.0 million to Softbank. Prior to the transactions, we held 100% of the equity of Nihon
Ariba and Ariba Korea in the form of common stock.

In October 2004, we purchased the 41% interest in Nihon Ariba and the 42% interest in
Ariba Korea held by Softbank for $3.5 million. During the remainder of 2005, we purchased the remaining 2% minority interest in Nihon Ariba held by minority shareholders. These transactions resulted in a $19.5 million reduction to minority interests
during the year ended September 30, 2005. For the year ended September 30, 2005, we increased consolidated net loss by $17,000, as the minority interests share of income.

Liquidity and Capital Resources

As of September 30, 2007, we had $153.0 million in cash, cash equivalents, marketable securities and long-term investments and $30.0 million in restricted cash, for total cash, cash equivalents, marketable securities, long-term
investments and restricted cash of $183.0 million. Our working capital on September 30, 2007 was $35.9 million. All significant cash, cash equivalents, marketable securities and long-term investments are held in accounts in the United States.
As of September 30, 2006, we had $138.8 million in cash, cash equivalents, marketable securities and long-term investments and $31.8 million in restricted cash, for total cash, cash equivalents, marketable securities, long-term investments and
restricted cash of $170.6 million. Our working capital on September 30, 2006 was $39.4 million.

The increase in total cash, cash
equivalents, marketable securities, long-term investments and restricted cash of $12.4 million in the year ended September 30, 2007 is primarily attributable to our results of operations, excluding non-cash charges for stock-based compensation
of $32.4 million, depreciation and amortization expense of $21.6 million and non-cash income of $13.6 million from the Softbank transaction. The increase in cash, cash equivalents, marketable securities, long-term investments and restricted cash is
also attributable to continued improved cash collections on outstanding accounts receivable in the year ended September 30, 2007.

Net
cash from operating activities was $16.6 million for the year ended September 30, 2007, compared to net cash from operating activities of $22.5 million for the year ended September 30, 2006. Cash flows from operating activities decreased
$6.0 million primarily due to a higher net loss excluding non-cash charges and a $2.0 million increase in payments on lease abandonment accruals due to a payment of $5.4 million associated

with surrendering the abandoned space in Pittsburgh, Pennsylvania, partially offset by a decline of $3.4 million associated with the Mountain View,
California lease that expired in October 2007.

Net cash from operating activities was $22.5 million for the year ended September 30,
2006, compared to net cash used in operating activities of $68.7 million for the year ended September 30, 2005. Cash flows from operating activities increased $91.2 million primarily due to the following: (1) an increase of $37.0 million
associated with the ePlus settlement in February 2005; (2) an increase of $23.0 million associated with the net Softbank activity. In the year ended September 30, 2005, we returned $43.0 million of the interim payments received in
connection with the Softbank arbitration proceedings, which represented the amounts owed to Ariba for software and support under the strategic relationship with Softbank, and received $20.0 million from Softbank for a three-year software license of
the Ariba Sourcing and Ariba Analysis product lines; (3) an increase from a $4.9 million insurance reimbursement related to litigation matters in the nine months ended September 30, 2006; (4) an increase from reduced cash payments of
restructuring obligations of $9.1 million in the year ended September 30, 2006 as compared to the year ended September 30, 2005, primarily for severance and benefit costs as part of the restructuring program in fiscal year 2004 to realign
our business model with FreeMarkets; (5) an increase from improved results of operations, excluding non-cash charges, in the year ended September 30, 2006 as compared to the year ended September 30, 2005; and (6) an increase from
improved collections on outstanding accounts receivable in the year ended September 30, 2006 as compared to the year ended September 30, 2005. These items were partially offset by a $12.4 million payment received from a subtenant in the
year ended September 30, 2005.

Net cash used in investing activities was $11.0 million for the year ended September 30, 2007,
compared to net cash used in investing activities of $37.1 million for the year ended September 30, 2006. The decrease is primarily attributable to the decrease in purchases of investments, net of sales of $27.9 million, partially offset by an
increase in capital expenditures of $2.3 million due to purchases of computer equipment in the year ended September 30, 2007.

Net
cash used in investing activities was $37.1 million for the year ended September 30, 2006, compared to net cash provided by investing activities of $42.7 million for the year ended September 30, 2005. The decrease is primarily attributable
to the allocation of the interim payments received in connection with the Softbank arbitration proceeding from restricted cash and the change in sales of marketable securities, net of purchases of $46.9 million, partially offset by the settlement of
the minority interests from Softbank and other minority interest shareholders of $4.4 million in the year ended September 30, 2005.

Net cash provided by financing activities was $3.0 million for the year ended September 30, 2007, compared to net cash provided by financing activities of $5.0 million for the year ended September 30, 2006. The repurchase of
common stock in both periods represents shares forfeited to Ariba by employees in satisfaction of statutory tax withholding obligations incurred as a result of the vesting of restricted shares of common stock held by those employees. Proceeds from
the issuance of common stock in both periods is attributed to stock option exercises and the employee stock purchase program. The decrease in net cash provided by financing activities in the year ended September 30, 2007 of $2.0 million is
attributed to a change in the terms of the employee stock purchase plan in August 2006 whereby the option component of the plan was eliminated (see Note 1 of Notes to Consolidated Financial Statements for further discussion).

Net cash provided by financing activities was $5.0 million for the year ended September 30, 2006, compared to net cash provided by financing
activities of $11.8 million for the year ended September 30, 2005. The decrease in net cash provided by financing activities in the year ended September 30, 2006 of $6.8 million is attributed to a $3.0 million increase in the repurchase of
common stock as a result of statutory tax withholding incurred upon the vesting of restricted shares of common stock held by employees and a $3.8 million decrease in proceeds from stock option exercises and the employee stock purchase plan due to
offering our employees the opportunity to exchange outstanding stock options for restricted shares of our common stock in the year ended September 30, 2005.

As of September 30, 2007, we did not have any commitments for capital expenditures.

Contractual obligations

Our primary
contractual obligations are under our operating leases and letters of credit which are discussed below.

In March 2000, we entered into a
facility lease agreement for 716,000 square feet in four office buildings and an amenities building in Sunnyvale, California for our headquarters. The operating lease term commenced in 2001 and ends in January 2013. We occupy 191,000 square feet in
this facility, and currently sublease two buildings totaling 356,000 square feet to third parties. These subleases expire in August 2008 and January 2013. The remaining 169,000 square feet is available for sublease. See Note 15 of Notes to
Consolidated Financial Statements. Minimum monthly lease payments are $3.0 million and escalate annually, with the total future minimum lease payments amounting to $217.1 million over the remaining lease term. As part of this lease agreement, we are
required to issue standby letters of credit backed by cash equivalents, totaling $29.3 million as of September 30, 2007, as a form of security through fiscal year 2013. Also, we are required by other lease agreements to hold an additional
$660,000 of standby letters of credit, which are cash collateralized. These instruments are issued by our banks in lieu of a cash security deposit required by landlords for domestic and international real estate leases. The total cash collateral of
$30.0 million is classified as restricted cash on our consolidated balance sheet as of September 30, 2007.

We also occupy 91,000
square feet of office space in Pittsburgh, Pennsylvania under a lease that expires in December 2017. This location consists principally of our services organization and administrative activities.

Future minimum lease payments and sublease income under noncancelable operating leases for the next five years and thereafter are as follows as of

The above table represents our estimates of future payments under fixed contractual obligations
and commitments. Changes in our business needs, cancellation provisions and other factors may result in actual payments differing from these estimates. We cannot provide certainty regarding the specific timing and actual amounts of payments.

Of the total operating lease commitments as of September 30, 2007 noted above, $100.9 million is for occupied properties and $152.2
million is for abandoned properties, which are a component of the restructuring obligation.

Other than the lease commitments and letters
of credit discussed above, we do not have commercial commitments under lines of credit, standby repurchase obligations or other such debt arrangements. We do not have any material noncancelable purchase commitments as of September 30, 2007.

Off-balance sheet arrangements

We have no off-balance sheet arrangements or transactions with unconsolidated limited purpose entities, nor do we have any undisclosed material
transactions or commitments involving related persons or entities.

Anticipated cash flows

We expect to incur significant operating costs, particularly related to services delivery costs, sales and marketing, research and development and
restructuring costs, for the foreseeable future in order to execute our business plan. We anticipate that such operating costs, as well as the pending acquisition of Procuri, will constitute a use of our cash resources. As a result, our net cash
flows will depend heavily on the level of future sales, changes in deferred revenues, our ability to manage infrastructure costs, the outcome of our subleasing activities related to abandoned excess leased facilities and ongoing regulatory and legal
proceedings.

We believe our existing cash, cash equivalents and investment balances, together with anticipated cash flow from operations,
should be sufficient to meet our working capital and operating resource requirements for at least the next twelve months. Should we find it necessary to obtain additional funds, we may not be able to obtain additional financing on favorable terms or
at all. See Risk Factors.

Application of Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (GAAP).
Accounting policies, methods and estimates are an integral part of the preparation of consolidated financial statements in accordance with GAAP and, in part, are based upon managements current judgments. Those judgments are normally based on
knowledge and experience with regard to past and current events and assumptions about future events. Certain accounting policies, methods and estimates are particularly sensitive because of their significance to the consolidated financial statements
and because of the possibility that future events affecting them may differ markedly from managements current judgments. While there are a number of accounting policies, methods and estimates affecting our consolidated financial statements,
areas that are particularly significant include revenue recognition policies, the assessment of recoverability of goodwill and other intangible assets, restructuring obligations related to abandoned operating leases and contingencies related to the
collectibility of accounts receivable and pending litigation. These policies and our practices related to these policies are described below and in Note 1 of Notes to Consolidated Financial Statements.

Revenue recognition

Substantially
all of our revenues are derived from three sources: (i) providing subscription software solutions on either a multi-tenant or single tenant basis and associated technical support and product updates, otherwise known as subscription and
maintenance; (ii) providing services, including implementation services, consulting services, training, education, premium support and other miscellaneous services; and (iii) licensing perpetual software. The significant majority of our
standard end user license agreements provide for use of our software under a time-based license based on the number of users or other usage criteria. We license our software in multiple element arrangements in which the customer typically purchases
a combination of some or all of the following: (i) software solutions, either on a standalone or on-demand basis; (ii) a maintenance arrangement, which is generally priced as a percentage of the software license fees and provides for
technical support and unspecified product updates typically over a period of one year or over the term of the license; and (iii) a services arrangement, on either a fixed fee for access to specific services over time or a time and materials
basis.

We license our products through our direct sales force and indirectly through resellers. Sales made through resellers are generally
recognized at the time that we have received persuasive evidence of an end user customer. The license agreements for our products generally do not provide for a right of return, and historically product



44

##### Table of Contents

returns have not been significant. We do not recognize revenue for refundable fees or agreements with cancellation rights until such rights to refund or
cancel have expired. Direct sales force commissions are included as sales and marketing expense at the time of sale, when the liability is incurred and is reasonably estimable.

We recognize revenue in accordance with SAB 104, Revenue Recognition, Emerging Issues Task Force (EITF) 00-21, Revenue Arrangements
with Multiple Deliverables, EITF 00-3, Application of AICPA Statement of Position 97-2 to Arrangements That Include the Right to Use Software Stored on Another Entitys Hardware, and Statement of Position (SOP) 97-2,
Software Revenue Recognition, as amended by SOP 98-9, Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions. We recognize revenue when all of the following criteria are met: persuasive
evidence of an arrangement exists; delivery of the product or service has occurred; the fee is fixed or determinable; and collectibility is probable. If fees are not fixed or determinable, revenue is recognized when fees are due and
payable. If collectibility is not considered probable at the inception of the arrangement, we do not recognize revenue until the fee is collected.

We allocate revenue to each element in a multiple element arrangement based on its respective fair value. Our determination of the fair value of each element in a multiple element arrangement accounted for under SOP 97-2 is based on
vendor-specific objective evidence (VSOE) of fair value, which is limited to the price when sold separately. VSOE or other methods of determining fair value that are allowable under EITF 00-21 are utilized for multiple element
arrangements that are not subject to SOP 97-2.

Revenue from software solutions, hosting and sourcing solutions services is primarily
recognized ratably over the term of the arrangement, commencing with the initial customer access date. Revenue allocated to maintenance and support is recognized ratably over the maintenance term (typically one year). Revenue allocated to software
solutions implementation, process improvement, training and other services is recognized as the services are performed or as milestones are achieved or if bundled with a subscription or time-based service, or in circumstances where fair value cannot
be established for undelivered service elements, is recognized ratably over the term of the access agreement.

Certain of our contracts
include performance incentive payments based on market volume and/or savings generated, as defined in the respective contracts. Revenue from such arrangements is recognized when those thresholds are achieved.

When revenue associated with multiple element arrangements is recognized and more than one element in an arrangement does not have fair value, we first
allocate revenue on the statement of operations to those elements for which evidence of fair value is available.

In circumstances where we
provide consulting services as part of a multi-element arrangement with software solutions, both the software solution revenue and service revenue are recognized under the lesser of proportional performance method based on hours or ratable over the
term of the license.

Deferred revenue includes amounts received from customers for which revenue has not been recognized, and generally
results from deferred subscription, maintenance and support, hosting, consulting or training services not yet rendered and recognizable under EITF 00-21 and license revenue deferred until all requirements of SOP 97-2 are met. Deferred revenue is
recognized as revenue upon delivery of the product, as services are rendered, or as other requirements under SAB 104, EITF 00-21 or SOP 97-2 are satisfied. Deferred revenue excludes contract amounts for which payment has yet to be collected.
Likewise, accounts receivable excludes amounts due from customers for which revenue has been deferred.

Allowance for doubtful accounts
receivable

We maintain an allowance for doubtful accounts at an amount we estimate to be sufficient to provide for actual losses
resulting from collecting less than full payment on our receivables. A considerable amount of



45

##### Table of Contents

judgment is required when we assess the realizability of receivables, including assessing the probability of collection and the current creditworthiness of
each customer. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, an additional provision for doubtful accounts might be required. In cases where we are aware of
circumstances that may impair a specific customers ability to meet its financial obligations, we record a specific allowance against amounts due, and thereby reduce the net recognized receivable to the amount we reasonably believe will be
collected. For the remaining customers, we recognize allowances for doubtful accounts based on the length of time the aggregate receivables are outstanding, the current business environment and historical experience. Alternatively, if the financial
condition of our customers were to improve such that their ability to make payments was no longer considered impaired, we would reduce related estimated reserves with a credit to the provision for doubtful accounts.

Recoverability of goodwill

We review
goodwill for impairment annually and more frequently if events and circumstances indicate that the asset may be impaired and that the carrying value may not be recoverable. Factors we consider important that could trigger an impairment review
include, but are not limited to, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for our overall business, significant
negative industry or economic trends, a significant decline in our stock price for a sustained period, and decreases in our market capitalization below the recorded amount of our net assets for a sustained period. Our stock price is highly volatile
and has experienced significant declines in the past. In June 2005, based on a combination of factors, particularly: (1) our market capitalization at that time; (2) our then current and projected operating results; (3) significant
trends in the enterprise software industry; and (4) our decision to reduce our workforce and eliminate excess facility space, we concluded there were sufficient indicators to require us to assess whether any portion of our recorded goodwill
balance was impaired. We determined that our estimated fair value was less than the recorded amount of our net assets, thereby necessitating that we assess our recorded goodwill for impairment. As required by SFAS No. 142, in measuring the
amount of goodwill impairment, we made a hypothetical allocation of the estimated fair value of the Company to the tangible and intangible assets (other than goodwill) and liabilities. Based on this allocation, we concluded that goodwill was
impaired in the amount of $247.8 million. We performed the annual assessment in the fourth quarter of fiscal years 2007 and 2006 and no further indication of goodwill impairment was noted. The remaining balance of goodwill is $326.1 million as of
September 30, 2007, and there can be no assurances that future goodwill impairments will not occur.

Impairment of long-lived
assets

We evaluate long-lived assets, such as property and equipment and purchased intangibles subject to amortization, for impairment
whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the estimated
undiscounted future cash flows expected to be generated from the use and ultimate disposition of the assets. If the carrying amount of the assets exceeds their estimated future cash flows, an impairment charge is recognized for the amount by which
the carrying amount of the assets exceeds the fair value of the assets.

Lease abandonment costs

We initially recorded a significant restructuring charge in the third quarter of fiscal year 2001 upon abandoning certain operating leases as part of a
program to restructure our operations and related facilities. In the years ended September 30, 2004, 2003 and 2002, we revised our original estimates and expectations for our corporate headquarters and field offices disposition efforts as a
result of changed estimates of sublease rental projections.

During the year ended September 30, 2005, we revised our estimates for
sublease rental projections resulting in a charge of $31.8 million. We also recorded a $1.6 million adjustment to our restructuring obligation

##### Table of Contents

in March 2005 that was related to a prior period. Based on the guidance in SAB 99, we concluded that the amount of the prior period error was immaterial to
fiscal years 2005 and 2004. In July 2005, we re-assessed our office space in Pittsburgh, Pennsylvania and ceased use of one of the floors we leased through 2010, which resulted in a charge of $1.2 million. Finally, we recorded a $1.2 million
adjustment to the restructuring obligation due to the closure of an excess legacy FreeMarkets facility. This restructuring adjustment was considered part of purchase accounting for FreeMarkets and was recorded as an adjustment to goodwill.

During the year ended September 30, 2006, we revised our estimates for sublease rental rate projections to reflect continued soft
market conditions in the Northern California real estate market and sublease commencement dates, resulting in a charge of $24.4 million. The remaining charge in the year ended September 30, 2006 was related to property taxes of $942,000 based
on a property tax audit assessment related to calendar years 2001 through 2004 (see Note 6 of Notes to Consolidated Financial Statements for further discussion) and an adjustment to the Companys restructuring obligation related to a prior
period. The cumulative understatement of expenses for periods prior to the year ended September 30, 2006 was approximately $730,000. We concluded that the effect of the adjustment was not material to fiscal year 2006 and the prior periods. We
recorded the cumulative understatement as an increase in restructuring and integration expense and to total operating expenses during the year ended September 30, 2006. During the year ended September 30, 2006, we also recorded a $472,000
decrease to the restructuring obligation due to the assignment of a lease of an excess legacy FreeMarkets facility. The reversal of the remaining obligation related to this facility was recorded as a decrease to goodwill.

During the year ended September 30, 2007, we recorded a net benefit to operations of $4.2 million. In June 2007, we entered into an amendment with
Juniper, the successor in interest to NetScreen to the sublease dated as of October 18, 2002 between Ariba and NetScreen. Pursuant to the amendment, Juniper agreed to renew its sublease of approximately 177,000 square feet of space at our
Sunnyvale, California headquarters through January 2013. In addition, Juniper agreed, effective October 10, 2007, to lease approximately 89,000 square feet of additional space at our Sunnyvale, California headquarters through
January 2013. Also in June 2007, we revised our estimates for rental rate projections and sub-lease commencement dates to reflect current market conditions primarily in the Northern California real estate market. The impact of the execution of
the sublease agreement with Juniper was a benefit to operations of approximately $7.3 million and the impact of the revised estimated rental rate projections and sub-lease commencement dates was a charge to operations of $3.2 million, resulting in a
net benefit to operations of $4.1 million in the year ended September 30, 2007.

Lease abandonment costs for the abandoned facilities
were estimated to include remaining lease liabilities and brokerage fees offset by estimated sublease income. Estimates related to sublease costs and income are based on assumptions regarding the period required to locate and contract with suitable
sublessees and sublease rates using market trend information analyses provided by a commercial real estate brokerage firm retained by us. We review these estimates each quarterly reporting period, and to the extent that our assumptions change, the
ultimate restructuring expenses for these abandoned facilities could vary significantly from current estimates. See Notes 6 and 15 of Notes to Consolidated Financial Statements.

As of September 30, 2007, we had contractual commitments of $152.2 million for abandoned properties. Our lease abandonment accrual is net of $71.3
million of estimated sublease income. Actual sublease payments due under noncancelable subleases of excess facilities totaled $42.1 million as of September 30, 2007 and the remainder of anticipated sublease income represents managements
estimate of amounts to be received under future subleases. Actual future cash requirements and lease abandonment costs may differ materially from the accrual at September 30, 2007, particularly if actual sublease income is significantly
different from current estimates. These differences could have a material adverse effect on our operating results and cash position. For example, a reduction in assumed market lease rates of $0.25 per square foot per month for the remaining term of
the lease, with all other assumptions remaining the same, would increase the estimated lease abandonment loss on our Sunnyvale, California headquarters by approximately $3.1 million as of September 30, 2007.

Legal contingencies

We are subject to various claims and legal actions. See Legal Proceedings. We accrue for estimated losses in accordance with GAAP for those matters where we believe that the likelihood that a loss has
occurred is probable and the amount of loss is reasonably estimable. Although we currently believe that we have properly accrued for estimable and probable losses regarding the outcome of outstanding legal proceedings, claims and litigation
involving us, litigation is inherently uncertain, and there can be no assurance that existing or future litigation will not have a material adverse effect on our business, results of operations or financial condition or that the current amount of
accrued losses is sufficient for any actual losses that may be incurred.

|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Foreign Currency Risk

We develop products primarily in the United States and India and market our products primarily in the
United States, Europe and Asia. As a result, our financial results could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets. Since the majority of our non-U.S. sales are priced in
currencies other than the U.S. dollar, a strengthening of the dollar may reduce the level of reported revenues. If any of the events described above were to occur, our net sales could be seriously impacted, since a large portion of our net sales are
derived from international operations. For the years ended September 30, 2007, 2006 and 2005, approximately 29%, 30% and 28%, respectively, of our total net sales were derived from customers outside of the United States. As a result, our U.S.
dollar earnings and net cash flows from international operations may be adversely affected by changes in foreign currency exchange rates.

We use derivative instruments to manage risks associated with foreign currency transactions in order to minimize the impact of changes in foreign currency exchange rates on earnings. We utilize forward contracts to reduce our net exposures,
by currency, related to the monetary assets and liabilities of our foreign operations denominated in local currency. In addition, from time to time, we may enter into forward exchange contracts to establish with certainty the U.S. dollar amount of
future firm commitments denominated in a foreign currency. These forward contracts do not qualify for hedge accounting and accordingly, all of these instruments are marked to market at each balance sheet date by a charge to earnings. We believe that
these forward contracts do not subject us to undue risk due to foreign exchange movements because gains and losses on these contracts are generally offset by losses and gains on the underlying assets and liabilities. We do not use derivatives for
trading or speculative purposes. All contracts have a maturity of less than one year.

The following table provides information about our
foreign exchange forward contracts outstanding as of September 30, 2007 (in thousands):

The unrealized gain (loss) represents the difference between the contract value and the market
value of the contract based on market rates as of September 30, 2007.

Given our foreign exchange position, a ten percent change in
foreign exchange rates upon which these forward exchange contracts are based would result in unrealized exchange gains or losses of approximately $600,000. In all material aspects, these exchange gains and losses would be fully offset by exchange
losses or gains on the underlying net monetary exposures. We do not expect material exchange rate gains and losses from other foreign currency exposures.

Interest Rate Risk

Our exposure to market risk for changes in interest rates relates primarily to
our investment portfolio. We do not use derivative financial instruments in our investment portfolio. The primary objective of our investment

##### Table of Contents

activities is to preserve principal while maximizing yields without significantly increasing risk. This is accomplished by investing in widely diversified
investments, consisting only of investment grade securities. We hold investments in both fixed rate and floating rate interest earning instruments, and both carry a degree of interest rate risk. Fixed rate securities may have their fair market value
adversely impacted due to a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall.

Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates, or we may suffer losses in principal if forced to sell securities which may have declined in market value due to
changes in interest rates. Our investments may fall short of expectations due to changes in market conditions and as such we may suffer losses at the time of sale due to the decline in market value. All investments in the table below are carried at
market value, which approximates cost.

The table below represents principal (or notional) amounts and related weighted-average interest
rates by year of maturity of our investment portfolio (in thousands, except for interest rates).

Report of Ernst & Young LLP, Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
of

Ariba, Inc.

We have audited the
accompanying consolidated balance sheets of Ariba, Inc. and subsidiaries as of September 30, 2007 and 2006, and the related consolidated statements of operations and comprehensive loss, stockholders equity, and cash flows for each of the
two years in the period ended September 30, 2007. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated
financial position of Ariba, Inc. and subsidiaries as of September 30, 2007 and 2006, and the consolidated results of their operations and their cash flows for each of the two years in the period ended September 30, 2007, in conformity
with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the effectiveness of Ariba, Inc.s internal control over financial reporting as of September 30, 2007, based on criteria established in Internal ControlIntegrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission and our report dated November 13, 2007 expressed an unqualified opinion thereon.

As discussed in Note 1 to the consolidated financial statements, the Company adopted Statement of Financial Accounting Standards No. 123(R), Share-Based Payment, effective October 1,
2005.

ARIBA, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1Description of Business and Summary of Significant Accounting Policies

Description of business

Ariba, Inc., along
with its subsidiaries (collectively referred to herein as the Company), is the leading provider of on-demand spend management solutions. The Companys solutions combine on-demand software, category expertise and services to help
companies automate the procurement process and drive best practice processes that lower costs, improve profits and increase competitive advantage. Ariba® Spend Management solutions
are easy to use, cost effective and quick to deploy, integrate with enterprise resource planning and other software systems and can be used by companies of all sizes across industries worldwide. The Company was incorporated in Delaware in September
1996.

Basis of presentation

The consolidated financial statements include the accounts of the Company. All significant intercompany accounts and transactions have been eliminated in consolidation. As of September 30, 2004, the Company had two subsidiaries with
less than 100% ownership, Nihon Ariba K.K. (Nihon Ariba) and Ariba Korea, Ltd. (Ariba Korea). In October 2004, the Company purchased the 41% interest in Nihon Ariba and the 42% interest in Ariba Korea held by Softbank Corp.,
a Japanese corporation, and its subsidiaries (collectively, Softbank). During the remainder of 2005, the Company purchased the remaining 2% minority interest in Nihon Ariba held by minority shareholders.

Prior period correction of an error

In connection with a review of the Companys deferred revenue accounts in the year ended September 30, 2007, a $19.1 million adjustment was made to increase the September 30, 2006 deferred revenue, current and decrease
deferred revenue, less current portion. The adjustment of deferred revenues corrected an error in the classification between deferred revenue, current and deferred revenues, less current portion. Total deferred revenues were not impacted by the
adjustment. As a result of changing its historical practices to conform to generally accepted accounting principles in the classification of determined revenue, the Company's previously reported deferred revenue, current had been
understated. The following table summarizes the change to the Consolidated Balance Sheet at September 30, 2006:



|                                       |  |                        |         |            |   |         |            |  |   |        
|-------------------------------------- |  | ---------------------- | ------- | ---------- | - | ------- | ---------- |  | - | -------
|                                       |  | As Previously Reported |         | Adjustment |   |         | As Revised
|Deferred revenue, current              |  | $                      | 40,035  |            | $ | 19,092  |            |  | $ | 59,127 
|Total current liabilities              |  | $                      | 124,641 |            | $ | 19,092  |            |  | $ | 143,733
|Deferred revenue, less current portion |  | $                      | 25,641  |            | $ | (19,092 | )          |  | $ | 6,549  

The Company did not amend its previously filed Annual Reports on Form 10-K or Quarterly Reports on
Form 10-Q for the correction of the error. Accordingly, the consolidated financial statements and related financial information contained in such reports should no longer be relied upon with respect to the Companys deferred revenue, current
and deferred revenue, less current portion, for the affected reporting periods. All referenced amounts for prior periods in the consolidated financial statements are presented on an as revised basis.

Reclassification

The Company reclassified $4.4 million and $2.0 million of compensation and benefits associated with certain employees from cost of revenuessubscription and maintenance in the years ended September 30, 2006 and
2005 to sales and marketing, respectively. The following table reflects the effects of this reclassification for the years ended September 30, 2006 and 2005 (in thousands):



|                                              |  |                               |        |                               |   |                        |  |                 |        |  |   |

|Sales and marketing                           |  | $                             | 78,071 |                               | $ | 82,456                 |  | $               | 92,262 |  | $ | 94,299

Use of estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management
to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported results of operations during the reporting period.
Actual results could differ from those estimates. The items that are significantly impacted by estimates include revenue recognition, the assessment of recoverability of goodwill and other intangible assets, restructuring obligations related to
abandoned operating leases and contingencies related to the collectibility of accounts receivable and pending litigation. In addition, we use assumptions to estimate the fair value of stock-based compensation.

Cash, cash equivalents and restricted cash

The Company considers all highly liquid investments with maturity dates of 90 days or less at the date of acquisition to be cash equivalents. Cash equivalents consist of money market funds, commercial paper, government/federal notes and
bonds and certificates of deposit. Restricted cash consists primarily of amounts held in deposits that are required as collateral under the Companys facilities operating lease agreements.

Marketable securities and long-term investments

Marketable securities and long-term investments consist primarily of AAA rated auction rate securities with readily determinable fair market values and with original maturities in excess of three months. Auction rate
securities are principally variable rate securities tied to short-term interest rates. They trade at par and are callable at par on any interest payment date at the option of the issuer. Interest paid during a given period is based upon the interest
rate determined during the prior auction. Interest income was approximately $9.2 million, $6.6 million and $3.1 million for the years ended September 30, 2007, 2006 and 2005, respectively. Although these instruments are issued and rated as
long-term securities, they are priced and traded as short-term securities because of the liquidity provided through the interest rate reset. The Companys auction rate securities are classified as available-for-sale and are reported at fair
value, with unrealized gains and losses recorded in stockholders equity. Realized gains or losses and other than temporary declines in value, if any, on available-for-sale securities are reported as other income or expense as incurred. The
Company periodically reviews these securities for other-than-temporary impairment.

Fair value of financial instruments and
concentration of credit risk

The carrying value of the Companys financial instruments, including cash and cash equivalents,
marketable securities, long-term investments, accounts receivable and accounts payable approximates fair value. Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents,
marketable securities, long-term investments and trade accounts receivable. The Company maintains

its cash, cash equivalents, marketable securities and long-term investments with high quality financial institutions and limits its investment in individual
securities based on the type and credit quality of each such security. The Companys customer base consists of international businesses, and the Company performs ongoing credit evaluations of its customers and generally does not require
collateral on accounts receivable. The Company maintains allowances for potential credit losses.

No customer accounted for more than 10%
of total revenues for the years ended September 30, 2007, 2006 and 2005. However, one customer accounted for more than 10% of net accounts receivable as of September 30, 2007 and 2006.

Allowance for doubtful accounts

The
Company evaluates the collectibility of accounts receivable based on a combination of factors. In cases where the Company is aware of circumstances that may impair a specific customers ability to meet its financial obligations, the Company
records a specific allowance against amounts due, and thereby reduces the net recognized receivable to the amount the Company reasonably believes will be collected. For the remaining customers, the Company recognizes allowances for doubtful accounts
based on the length of time the aggregate receivables are outstanding, the current business environment and historical experience.

Derivative financial instruments and foreign currency management

The Company considers the functional currency of its
foreign subsidiaries to be the local currency, and accordingly, the foreign subsidiaries financial statements are translated into U.S. dollars using exchange rates in effect at period end for assets and liabilities and average exchange rates
during each reporting period for the results of operations. Adjustments resulting from translations of foreign subsidiary financial statements are reported in accumulated other comprehensive income. Gains or losses on foreign currency transactions
are recognized in current operations in interest and other income, net. The Company recognized gains of approximately $2.2 million, $892,000 and $1.0 million for the years ended September 30, 2007, 2006 and 2005, respectively.

The Company uses derivative financial instruments for the purpose of reducing its exposure to adverse fluctuations in foreign exchange rates. While these
hedging instruments are subject to fluctuations in value, such fluctuations are generally offset by the value of the underlying exposures being hedged. The Company is not a party to leveraged derivatives and does not hold or issue financial
instruments for speculative purposes.

The Company routinely uses forward exchange contracts to hedge its net exposures, by currency,
related to the monetary assets and liabilities of its operations denominated in non-functional currency. The Company utilizes forward exchange contracts to hedge trade and intercompany receivables and payables. In addition, from time to time, the
Company may enter into forward exchange contracts to establish with certainty the U.S. dollar amount of future firm commitments denominated in a foreign currency. The primary business objective of this hedging program is to minimize the gains and
losses resulting from exchange rate changes.

The forward foreign exchange contracts require the Company to exchange foreign currencies for
U.S. dollars or vice versa and such contracts generally mature in six months or less. These contracts are marked to market through operations each period. As of September 30, 2007, the Companys outstanding foreign exchange contracts were
in Euros (EUR), Japanese Yen (JPY), Swiss Francs (CHF), Czech Koruna (CZK), Singapore Dollars (SGD) and British Pounds (GBP) and had a notional amount of $6.0 million, and these contracts had remaining maturities of three months or less. As of
September 30, 2006, the Companys outstanding foreign exchange contracts in Czech Koruna (CZK), Euros (EUR), Swiss Francs (CHF), Singapore Dollars (SGD) and Japanese Yen (JPY) had a notional amount of $7.6 million, and these contracts had
remaining maturities of three months or less.

In January 2005 and December 2004, the Company hedged a portion of the net assets of Ariba Korea and
Nihon Ariba, respectively, using foreign currency forward contracts (Korean Won and Japanese Yen) to offset the translation and economic exposures related to anticipated cash flows from these subsidiaries. The Korean Won and Japanese Yen hedges were
entered into to minimize currency risk arising from cash held in Korean Won and Japanese Yen as a result of the Softbank settlement in October 2004. In September 2005, the cash held in Nihon Ariba was repatriated and a gain of $2.3 million was
realized on these foreign currency contracts in the fourth quarter of fiscal year 2005. The change in fair value of the Korean Won forward contract attributable to the changes in forward exchange rates (the effective portion) was reported in
stockholders equity in the periods prior to the cash being repatriated. In the year ended September 30, 2007, the Company recorded a net realized gain of $2.2 million associated with the repatriation of cash from Ariba Korea and
liquidation of the Ariba Korea entity, which is comprised of a $2.5 million gain from foreign currency translation adjustments and a $285,000 realized loss on the Korean Won cash flow hedge.

Property and equipment

Property and
equipment are stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method over the shorter of the estimated useful lives of the assets, generally two to five years based on asset
classification, or the lease term, if applicable. Gains and losses on disposals are included in results of operations at amounts equal to the difference between the net book value of the disposed assets and the proceeds received upon disposal. Costs
for replacements and betterments are capitalized, while the costs of maintenance and repairs are charged against earnings as incurred.

Impairment of long-lived assets

In accordance with Statement of Financial Accounting Standards (SFAS)
No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, long-lived assets, such as property and equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the estimated undiscounted future cash flows
expected to be generated from the use and ultimate disposition of the assets. If the carrying amount of the assets exceed its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the assets
exceed the fair value of the assets. Assets to be disposed of would be reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified as held
for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheet.

Goodwill and
other intangible assets

Purchased other intangible assets with finite lives are amortized over the estimated economic lives of the
assets, generally ranging from one to five years, and reviewed for impairment in accordance with SFAS No. 144. Goodwill and purchased other intangible assets determined to have indefinite useful lives are not amortized but are reviewed for
impairment annually and more frequently if events and circumstances indicate the assets may be impaired and the carrying value may not be recoverable. The Company has no identifiable intangible assets with indefinite lives as of September 30,
2007.

Factors the Company considers important that could trigger an impairment review of goodwill include, but are not limited to,
significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for the Companys overall business, significant negative industry or
economic trends, a significant decline in the Companys stock price for a sustained period, and decreases in the Companys market capitalization below the recorded amount of the Companys net assets for a sustained period. The
Companys stock price is highly volatile and has experienced significant declines since January 2004. In June 2005, based on a combination of factors, particularly: (1) the

Companys then current market capitalization; (2) the Companys then current and projected operating results; (3) significant trends in
the enterprise software industry; and (4) the Companys decision to reduce its workforce and eliminate excess facility space, the Company concluded there were sufficient indicators to require it to assess whether any portion of the
Companys recorded goodwill balance was impaired. The Company determined that its estimated fair value was less than the recorded amount of the Companys net assets, thereby necessitating that it assess the recorded goodwill for
impairment. As required by SFAS No. 142, Goodwill and Other Intangible Assets, in measuring the amount of goodwill impairment, the Company made a hypothetical allocation of the estimated fair value of the Company to the tangible and
intangible assets (other than goodwill) and liabilities. Based on this allocation, the Company concluded that goodwill was impaired in the amount of $247.8 million. The Company performed the annual assessment in the fourth quarter of fiscal years
2007, 2006 and 2005 and no further indication of impairment was noted. The remaining balance of goodwill is $326.1 million as of September 30, 2007, and there can be no assurances that future goodwill impairments will not occur.

Revenue recognition

Substantially
all of the Companys revenues are derived from three sources: (i) providing software solutions on either a multi-tenant or single tenant basis and technical support and product updates, otherwise known as subscription and maintenance;
(ii) providing services, including implementation services, consulting services, managed services, training, education, premium support and other miscellaneous services; and (iii) licensing perpetual software. The significant majority of
the Companys standard end user license agreements provide for use of the Companys software under a time-based license based on the number of users or other usage criteria. The Company licenses its software in multiple element
arrangements in which the customer typically purchases a combination of some or all of the following: (i) software solutions, either on a standalone or on-demand basis; (ii) a maintenance arrangement, which is generally priced as a
percentage of the software license fees and provides for technical support and unspecified product updates typically over a period of one year or over the term of the license; and (iii) a services arrangement, on either a fixed fee for access
to specific services over time or a time and materials basis.

The Company licenses its products through its direct sales force and
indirectly through resellers. Sales made through resellers are recognized at the time that the Company has received persuasive evidence of an end user customer. The license agreements for the Companys products generally do not provide for a
right of return, and historically product returns have not been significant. The Company does not recognize revenue for refundable fees or agreements with cancellation rights until such rights to refund or cancel have expired. Direct sales force
commissions are accounted for as sales and marketing expense at the time of sale, when the liability is incurred and is reasonably estimable.

The Company recognizes revenue in accordance with Staff Accounting Bulletin (SAB) 104, Revenue Recognition, Emerging Issues Task Force (EITF) 00-21, Revenue Arrangements with Multiple Deliverables, EITF
00-3, Application of AICPA Statement of Position 97-2 to Arrangements That Include the Right to Use Software Stored on Another Entitys Hardware, and Statement of Position (SOP) 97-2, Software Revenue Recognition, as
amended by SOP 98-9, Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions. The Company recognizes revenue when all of the following criteria are met: persuasive evidence of an arrangement exists;
delivery of the product or service has occurred; the fee is fixed or determinable; and collectibility is probable. If fees are not fixed or determinable, revenue is recognized when fees are due and payable. If collectibility is not
considered probable at the inception of the arrangement, the Company does not recognize revenue until the fee is collected.

The Company
allocates revenue to each element in a multiple element arrangement based on its respective fair value. The Companys determination of the fair value of each element in a multiple element arrangement accounted for under SOP 97-2 is based on
vendor-specific objective evidence (VSOE) of fair value, which is limited to the price when sold separately. VSOE or other methods of determining fair value that are allowable under EITF 00-21 are utilized for multiple element
arrangements that are not subject to SOP 97-2.

##### Table of Contents

Revenue from software solutions, hosting and sourcing solutions services is primarily recognized ratably
over the term of the arrangement, commencing with the initial customer access date. Revenue allocated to maintenance and support is recognized ratably over the maintenance term (typically one year). Revenue allocated to software solutions
implementation, process improvement, training and other services is recognized as the services are performed or as milestones are achieved or if bundled with a subscription or time-based arrangement or in circumstances where fair value cannot be
established for undelivered service elements, is recognized, ratably over the term of the access agreement.

Certain of the Companys
contracts include performance incentive payments based on market volume and/or savings generated, as defined in the respective contracts. Revenue from such arrangements is recognized when those thresholds are achieved.

When revenue associated with multiple element arrangements is recognized and more than one element in an arrangement does not have fair value, the
Company first allocates revenue on the statement of operations to those elements for which evidence of fair value is available.

In
circumstances where the Company provides consulting services as part of a multi-element arrangement with software solutions, both the software solution revenue and service revenue are recognized under the lesser of proportional performance method
based on hours or ratable over the term of the license.

Deferred revenue includes amounts received from customers for which revenue has
not been recognized, and generally results from deferred subscription, maintenance and support, hosting, consulting or training services not yet rendered and recognizable under EITF 00-21 and license revenue deferred until all requirements of SOP
97-2 are met. Deferred revenue is recognized as revenue upon delivery of the Companys product, as services are rendered, or as other requirements under SAB 104, EITF 00-21 or SOP 97-2 are satisfied. Deferred revenue excludes contract amounts
for which payment has yet to be collected. Likewise, accounts receivable excludes amounts due from customers for which revenue has been deferred.

Software development costs

In accordance with SFAS No. 86, Accounting for the Costs of Computer Software to be
Sold, Leased, or Otherwise Marketed, software development costs are expensed as incurred until technological feasibility, defined as a working prototype, has been established, at which time such costs are capitalized until the product is
available for general release to customers. To date, the Companys software has been available for general release shortly after the establishment of technological feasibility and, accordingly, capitalized development costs have not been
material.

The Company follows the guidance set forth in SOP 98-1, Accounting for the Costs of Computer Software Developed or Obtained
for Internal Use, in accounting for the development of its on-demand application service. SOP 98-1 requires companies to capitalize qualifying computer software costs which are incurred during the application development stage and to amortize
such costs over the softwares estimated useful life, which is three years. To date, qualifying costs eligible for capitalization under SOP 98-1 have not been material to the Companys consolidated financial statements.

Advertising expense

Advertising
costs are expensed as incurred and totaled $743,000, $154,000 and $3.2 million during the years ended September 30, 2007, 2006 and 2005, respectively.

Stock-based compensation and deferred stock-based compensation

The Company maintains stock-based
compensation plans which allow for the issuance of stock options and restricted common stock to executives and certain employees. The Company also maintains an employee stock

purchase plan (ESPP) that provides for the issuance of shares to all eligible employees of the Company at a discounted price. Prior to fiscal
year 2006, the Company accounted for the plans under the recognition and measurement provisions of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations.
Accordingly, because stock options granted had an exercise price equal to the market value of the underlying common stock on the date of the grant, no expense related to employee stock options was recognized. Also, as the employee stock purchase
plan was considered noncompensatory, no expense related to this plan was recognized. However, expense related to the grant of restricted stock had been recognized in the statement of operations under APB Opinion No. 25. In accordance with SFAS
No. 123, Accounting for Stock-Based Compensation,and SFAS No. 148, Accounting for Stock-Based CompensationTransition and Disclosure,the Company provided pro forma net loss and net loss per share disclosures for each
period prior to the adoption of SFAS No. 123R, Share-Based Payment, as if it had applied the fair value-based method in measuring compensation expense for its share-based compensation plans.

Effective October 1, 2005, the Company adopted the fair value recognition provisions of SFAS No. 123R. This statement applies to all awards
granted after the effective date and to modifications, repurchases or cancellations of existing awards. Additionally, under the modified prospective transition method of adoption, the Company recognizes compensation expense for the portion of
outstanding awards on the adoption date for which the requisite service period has not yet been rendered based on the grant-date fair value of those awards calculated under SFAS No. 123 and SFAS No. 148. As a result of the adoption of SFAS
No. 123R, the Company eliminated $35.5 million of deferred compensation, which represented unrecognized compensation cost for restricted stock awards, in the three months ended December 31, 2005. The Company also adjusted goodwill by $2.1
million as of October 1, 2005, which represented the unamortized deferred stock-based compensation of unvested stock options as of October 1, 2005 assumed in the merger with FreeMarkets in July 2004. Because the Company used the modified
prospective transition method, financial statements for prior periods have not been restated. The Company amortizes the fair value of awards granted both before and after October 1, 2005 on an accelerated basis.

SFAS No. 123R requires that forfeitures be estimated over the vesting period of an award, rather than being recognized as a reduction of
compensation expense when the forfeiture actually occurs. The cumulative effect of the use of the estimated forfeiture method for prior periods upon adoption of SFAS No. 123R was not material.

Comparable Disclosures

As discussed
above in this Note, the Company accounted for share-based employee compensation under SFAS No. 123Rs fair value method during the years ended September 30, 2007 and 2006. Prior to October 1, 2005, the Company accounted for
share-based employee compensation under the provisions of APB Opinion No. 25 and did not adopt the recognition provisions of SFAS No. 123. Accordingly, the Company recorded no share-based compensation expense for its stock options or its
employee stock purchase plan for the year ended September 30, 2005. The following table illustrates the effect on the Companys net loss and net loss per share for the year ended September 30, 2005 if it had applied the fair value
recognition provisions of SFAS No. 123R to share-based compensation using the Black-Scholes valuation model (in thousands, except per share amounts):

Determining Fair Value

Valuation and amortization method.The Company estimates the fair value of stock options granted using the Black-Scholes option valuation model and
a multiple option award approach. All options are amortized over the requisite service periods of the awards, which are generally the vesting periods, and are amortized using the accelerated method.

Expected term. The expected term of options granted represents the period of time that they are expected to be outstanding. The Company estimates
the expected term of options granted based on historical exercise patterns, which the Company believes are representative of future behavior.

Expected volatility. The Company estimates the volatility of its common stock in the Black-Scholes option valuation at the date of grant based on historical volatility rates over the expected term, consistent with SFAS No. 123R.

Risk-free interest rate.The Company bases the risk-free interest rate in the Black-Scholes option valuation model on the implied
yield in effect at the time of option grant on U.S. Treasury zero-coupon issues with equivalent remaining terms.

Dividends.The
Company has never paid any cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future. Consequently, the Company uses an expected dividend yield of zero in the Black-Scholes option valuation model.

Forfeitures.SFAS No. 123R requires the Company to estimate forfeitures at the time of grant and revise those estimates in
subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records share-based compensation expense only for those awards that are expected to vest. For
purposes of calculating pro forma information under SFAS No. 123 for periods prior to fiscal year 2006, the Company accounted for forfeitures only as they occurred.

The Company did not grant stock options in the year ended September 30, 2007. The Company granted 8,600 options in the year ended September 30, 2006. The fair value of options granted were estimated at the
date of grant using the Black-Scholes option pricing model and the following assumptions: expected life of 2.5 years, risk-free interest rate of 4.37%, volatility of 79% and dividend yield of 0%. The Company granted 1.6 million options in the
year ended September 30, 2005. The fair value of options granted were estimated at the date of grant using the Black-Scholes option pricing model and the following assumptions: expected life of 2.5 years, risk-free interest rate of 3.88%,
volatility of 92% and dividend yield of 0%.

The Company modified the terms of its employee stock purchase plan in August 2006 to eliminate
the option component associated with the plan. The fair value of the option component of the employee stock purchase plan prior to August 2006 was estimated at the date of grant using a Black-Scholes option-pricing model. The following
weighted-average assumptions were used in each quarter of fiscal 2006: expected life of 1.25 years, risk-free interest rate of 4.34%, volatility of 51% and dividend yield of 0%. The following weighted-average assumptions were used in each quarter of
fiscal 2005: expected life of 1.25 years, risk-free interest rate of 3.89%, volatility of 45% and dividend yield of 0%.

During the year
ended September 30, 2007, the Company accelerated approximately 259,000 unvested stock options, which resulted in approximately $1.0 million of compensation cost. During the years ended September 30, 2007, 2006 and 2005, the Company
recorded $2.4 million, $9.4 million and $1.1 million, respectively, of stock-based compensation expense associated with employee and director stock options and employee stock purchase plan programs.

During the years ended September 30, 2007, 2006 and 2005, the Company granted 1.9 million, 3.6 million and 7.6 million shares,
respectively, of restricted common stock to executive officers and certain employees with



65

##### Table of Contents

a fair value of $17.5 million, $31.7 million and $53.9 million, respectively. These amounts will be amortized in accordance with Financial Accounting
Standards Board (FASB) Interpretation No. 28 (FIN 28), Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans, over the vesting period of the individual restricted common stock
grants, which are two to three years. During the year ended September 30, 2007, the Company also granted 980,000 shares of restricted common stock to executive officers and certain key employees with a fair value of $7.5 million whose vesting
is contingent upon meeting a performance milestone related to subscription software revenues and is being amortized over the performance period. The fair value of each restricted share granted was calculated based on the closing stock price on the
date of grant and based on the assumption that the performance objective milestone will be achieved. If the performance objective is not achieved and the shares fail to vest, any previously recognized compensation cost will be reversed. During the
years ended September 30, 2007, 2006 and 2005, the Company recorded $27.5 million, $30.4 million and $18.5 million, respectively, of stock-based compensation expense associated with restricted stock grants. As of September 30, 2007, there
was $22.0 million of unrecognized compensation cost related to non-vested restricted share-based compensation arrangements which is expected to be recognized over a weighted-average period of 0.8 years. Total unrecognized compensation cost will
be adjusted for future changes in estimated forfeitures.

The Company also made a contribution to the Ariba, Inc. Employees 401(k) Savings
Plan (the 401(k) Plan) in the form of common stock with a value of $2.5 million, $1.4 million and $0 in the years ended September 30, 2007, 2006 and 2005, respectively.

Total stock-based compensation of $32.4 million, $41.2 million and $19.6 million was recorded in the years ended September 30, 2007, 2006 and 2005,
respectively, to various operating expense categories as follows (in thousands):

Income taxes

Income taxes are computed using an asset and liability approach, which requires the recognition of taxes payable or refundable for the current year and deferred tax assets and liabilities for the future tax
consequences of events that have been recognized in the Companys consolidated financial statements or tax returns. The measurement of current and deferred tax assets and liabilities is based on provisions of the enacted tax law; the effects of
future changes in tax laws or rates are not anticipated. The Company has recorded a valuation allowance for the full amount of the net deferred tax assets, as it is more likely than not that the deferred tax assets will not be realized.

Net loss per share

Net loss per
share is calculated in accordance with SFAS No. 128, Earnings per Share. Under the provisions of SFAS No. 128, basic net loss per share is computed by dividing the net loss for the period by the weighted average number of common
shares outstanding during the period, excluding restricted common stock subject to forfeiture. Diluted net loss per share is computed by dividing the net loss for the period by the weighted average number of common shares, including restricted
common stock subject to forfeiture and potential common shares outstanding during the period if their effect is dilutive. Potential common shares are comprised of incremental common shares issuable upon the exercise of stock options and warrants and
employee stock purchase plans shares.

translation adjustment.

Adoption of accounting standards and new accounting standards

In September 2006, the FASB issued Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes. FIN 48 clarifies
the accounting for uncertainty in income taxes in an enterprises financial statements in accordance with SFAS No. 109, Accounting for Income Taxes. FIN 48 also prescribes a recognition threshold and measurement attribute for the
financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
FIN 48 is effective for fiscal years beginning after December 15, 2006. The provisions of FIN 48 are effective for the first quarter of fiscal year 2008 and the Company is currently evaluating the impact of this guidance on its financial
position, results of operation and cash flows.

In September 2006, the FASB issued SFAS No. 157, Fair Value
Measurements. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in accordance with generally accepted accounting principles, and expands disclosures about fair value measurements. The provisions of SFAS
No. 157 are effective for the fiscal year beginning October 1, 2008. The Company is evaluating the impact of the provisions of SFAS No. 157.

In September 2006, the Securities and Exchange Commission (SEC) issued SAB 108, which provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be
considered in quantifying a current year misstatement. SAB 108 was effective for the Companys fiscal year beginning October 1, 2006. The adoption of SAB 108 did not have a material impact on the Companys financial position, results
of operations or cash flows.

In June 2006, the FASB reached a consensus on EITF 06-3, How Taxes Collected from Customers and
Remitted to Governmental Authorities Should Be Presented in the Income Statement (That Is, Gross versus Net Presentation).EITF 06-3 indicates that the statement of operations presentation on either a gross basis or a net basis of the taxes
within the scope of the issue is an accounting policy decision that should be disclosed. EITF 06-3 is effective for interim and annual periods beginning after December 15, 2006. The adoption of EITF 06-3 did not change the
Companys policy of presenting the taxes within the scope of EITF 06-3 on a net basis and, therefore, had no impact on the consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, including an amendment of FASB Statement No. 115, which allows an entity the
irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on an instrument-by-instrument basis. Subsequent measurements for the financial assets and liabilities an entity elects to
record at fair value will be recognized in earnings. SFAS No. 159 also establishes additional disclosure requirements. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007, with early adoption permitted
provided that the entity also adopts SFAS No. 157. The Company is currently evaluating the impact of the provisions of SFAS No. 159.

Note
2Balance Sheet Components

The Company evaluates the collectibility of accounts receivable based on a combination of factors. In
cases where the Company is aware of circumstances that may impair a specific customers ability to meet its financial obligations, the Company records a specific allowance against amounts due, and thereby reduces the net

recognized receivable to the amount the Company reasonably believes will be collected. For the remaining customers, the Company recognizes allowances for
doubtful accounts based on the length of time the aggregate receivables are outstanding, the current business environment and historical experience. The provision for doubtful accounts is included in sales and marketing expense in the Companys
consolidated statements of operations.

The marketable securities as of September 30, 2007 and 2006 due after three years are
primarily auction rate securities with an interest reset date or put date within 30 days. The Company had a $510,000 gross unrealized loss on an auction rate security as of September 30, 2007. Because the Company has the ability and intent to
hold this investment until a recovery of fair value, which may be maturity, the Company does not consider the investment to be other-than-temporarily impaired at September 30, 2007. During the year ended September 30, 2006, the Company
determined that its investments in privately held companies in the technology sector had incurred a decline in value that was other-than-temporary. Recognition of the impairment resulted in a charge to other expense for the year ended
September 30, 2006 totaling $149,000. As of September 30, 2007 and 2006, the fair value of remaining strategic investments is approximately $349,000 and $447,000, respectively, which is classified as a long-term asset.

##### Table of Contents

allowance for the years ended September 30, 2007, 2006 and 2005 was $12.5 million, $21.7 million and $(47.1) million, respectively. Included in the net
operating loss carryforwards is a tax benefit attributable to noncompensatory stock options of approximately $339.6 million at September 30, 2007 which, when and if realized, will be recorded as a credit to additional paid-in capital.

Utilization of the Companys net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to
the ownership change limitations imposed by Internal Revenue Code Sections 382 and 383 and similar state provisions. Such an annual limitation could result in the expiration of the Companys federal and state net operating loss and tax
credit carryforwards before utilization.

As of September 30, 2007, the Company had net operating loss carryforwards for federal,
state and foreign tax purposes of approximately $1.4 billion and $760.0 million and $4.2 million, respectively, before consideration of any annual limitation as described above. These federal, state and foreign net operating loss carryforwards
expire in various years from fiscal year 2010 through fiscal year 2027, from fiscal year 2008 through fiscal year 2027 and from fiscal year 2010 through fiscal year 2013, respectively. As of September 30, 2007, the Company had research credit
carryforwards for federal and state tax purpose of approximately $39.0 million and $25.1 million, respectively. If not utilized, the federal research credit carryforwards will expire in various years from fiscal year 2010 through fiscal year 2023.
The state research credit carryforwards will continue indefinitely, except for approximately $244,000 which will expire in fiscal year 2018. The Company also had manufacturers credit carryforwards as of September 30, 2007 for state tax
purposes of approximately $2.0 million, which will expire in various years from fiscal year 2008 through fiscal year 2012. The Companys net operating loss and tax credit carryforwards include net operating loss and research credit
carryforwards of approximately $250.3 million and $5.1 million, respectively, generated by FreeMarkets, which are subject to annual limitations which could reduce or defer the utilization of those losses and credits.

During fiscal year 2007, the Internal Revenue Service (IRS) made an adjustment to the Companys U.S. income tax return for fiscal year
2003 which resulted in an approximate $3.8 million reduction in the Companys net operating loss for that year and an extension of the amortization period for an intangible asset. The Company is also being audited by numerous state and non-U.S.
tax authorities. The Company believes that it has adequately accrued for any reasonably foreseeable outcome related to these audits.

The
undistributed earnings of the foreign subsidiaries is approximately $27.7 million as of September 30, 2007. The Company has decided to permanently reinvest those earnings and accordingly has not provided for any taxes thereon, with the
exception of approximately $4.0 million for Nihon Ariba. The Company plans to repatriate this amount in the next three to six months.

Leases

In March 2000, the Company entered into a facility lease agreement for approximately 716,000 square feet in four office buildings and an amenities building in Sunnyvale, California for its headquarters. The operating
lease term commenced in January 2001 through April 2001 and ends in January 2013. The Company occupies approximately 191,000 square feet in this facility. The Company currently subleases two buildings, totaling 356,000 square feet, to third parties.
These subleases expire in August 2008 and January 2013. The remaining 169,000 square feet is available for sublease. Minimum monthly lease payments are approximately $3.0 million and escalate annually, with the total future minimum lease payments
amounting to $217.1 million over the remaining lease term. As part of this lease agreement, the Company is required to issue standby letters of credit backed by cash equivalents, totaling $29.3 million as of September 30, 2007, as a form of
security through fiscal year 2013. Also, the Company is required by other lease agreements to hold an additional $660,000 of standby letters of credit, which are cash collateralized. These instruments are issued by its banks in lieu of a cash
security deposit required by landlords for domestic and international real estate leases. The total cash collateral of $30.0 million is classified as restricted cash on the Companys consolidated balance sheet as of September 30, 2007.

that expires in December 2017. This location consists principally of the Companys services organization and administrative activities.

The Company leases certain equipment, software and its facilities under various noncancelable operating and immaterial capital leases with various expiration dates through 2017. Gross operating rental expense was approximately $30.9
million, $33.6 million and $34.5 million for the years ended September 30, 2007, 2006 and 2005, respectively. Gross operating rental expense was reduced by sublease income of $14.4 million, $17.2 million and $17.5 million for the years ended
September 30, 2007, 2006 and 2005, respectively.

Severance and benefits costs

Severance and benefits costs primarily include involuntary termination and health benefits, outplacement costs and payroll taxes for terminated personnel.
During the year ended September 30, 2006, an additional $273,000 of severance and benefits was recorded due to the continued reduction of the Companys workforce, primarily to better align its expenses with its revenue levels and to enable
the Company to invest in certain growth initiatives.

During the year ended September 30, 2005, an additional $3.8 million of
severance and benefits was recorded due to the continued reduction of the Companys workforce, by approximately 115 employees in all business areas, primarily to better align its expenses with its revenue levels and to enable the Company to
invest in certain growth initiatives. The remaining amount in the year ended September 30, 2005 of $1.6 million related to severance and related benefits as a result of the merger with FreeMarkets.

Lease abandonment and leasehold impairment costs

Lease abandonment costs incurred to date relate primarily to the abandonment of leased facilities in Mountain View and Sunnyvale, California and Pittsburgh, Pennsylvania. Total lease abandonment costs include lease
liabilities offset by estimated sublease income, and were based on market trend information analyses. As of September 30, 2007, $71.2 million of lease abandonment costs remain accrued and are expected to be paid by fiscal year 2013.

In February 2007, the Company entered into the sixth amendment to its lease in Pittsburgh, Pennsylvania,
effective January 1, 2007. The amendment extends the lease term for approximately 91,000 square feet of office space that the Company occupies through December 2017. Effective January 1, 2007, the Company also surrendered approximately
91,000 square feet of abandoned space it leased and made a payment of approximately $5.4 million to the landlord concurrent with the landlords signing of the sixth amendment in February 2007. The difference between the Companys lease
abandonment reserve associated with this abandoned space and the payment of $5.4 million is approximately $901,000 and is being recognized as contra rent expense over the remaining term of the lease through December 2017.

In June 2007, the Company entered into an amendment with Juniper Networks, Inc. (Juniper), the successor in interest to NetScreen
Technologies, Inc. (NetScreen) to the sublease dated as of October 18, 2002 between the Company and NetScreen. Pursuant to the amendment, Juniper agreed to renew its sublease of approximately 177,000 square feet of space at the
Companys Sunnyvale, California headquarters through January 2013. In addition, Juniper agreed, effective no later than December 1, 2007, to lease approximately 89,000 square feet of additional space at the Companys Sunnyvale,
California headquarters through January 2013. See also Note 15 of Notes to Consolidated Financial Statements. The Companys Chief Executive Officer, Robert Calderoni, is also on the Board of Directors of Juniper and he abstained from
voting on Aribas Board of Directors approval of the lease agreement. Also in June 2007, the Company revised its estimates for rental rate projections and sublease commencement dates to reflect current market conditions primarily in the
Northern California real estate market. The impact of the execution of the amendment to the sublease agreement with Juniper was a benefit to operations of approximately $7.3 million and the impact of the revised estimated rental rate projections and
sub-lease commencement dates was a charge to operations of $3.2 million, resulting in a net benefit to operations of $4.1 million in the year ended September 30, 2007.

During the year ended September 30, 2006, the Company revised its estimates for sublease rental rate projections to reflect continued soft market
conditions in the Northern California real estate market and sublease commencement dates, resulting in a charge of $24.4 million. The remaining charge in the year ended September 30, 2006 was for property taxes of $942,000 related to abandoned
facilities in California based on a property tax assessment related to calendar years 2001 through 2004 and an adjustment of $730,000 to the Companys restructuring obligation related to a prior period. The Company concluded that the effect of
the adjustment was not material to fiscal year 2006 or the prior periods. The Company recorded the $730,000 understatement as an increase in restructuring and integration expense and to total operating expenses during the year ended
September 30, 2006. During the year ended September 30, 2006, the Company also recorded a $472,000 decrease to the restructuring obligation due to the assignment of a lease of an excess legacy FreeMarkets facility. The reversal of the
remaining obligation related to this facility has been recorded as a decrease to goodwill.

During the year ended September 30, 2005,
the Company revised its estimates for sublease rental projections resulting in a charge of $31.8 million. The Company also recorded a $1.6 million adjustment to its restructuring obligation in March 2005 that was related to a prior period. Based on
the guidance in SAB 99, the Company concluded that the amount of the prior period error was immaterial to fiscal years 2005 and 2004. In July 2005, the Company re-assessed its office space in Pittsburgh, Pennsylvania and ceased use of one of the
floors it leases through 2010, which resulted in a charge of $1.2 million. Finally, the Company also recorded a $1.2 million adjustment to the restructuring obligation due to the closure of an excess legacy FreeMarkets facility. This restructuring
adjustment was considered part of purchase accounting for FreeMarkets and has been recorded as an adjustment to goodwill.

The
Companys lease abandonment accrual is net of $71.3 million of estimated sublease income. Actual sublease payments due under noncancelable subleases of excess facilities totaled $42.1 million as of September 30, 2007, and the remainder of
anticipated sublease income represents managements best estimates of amounts to be received under future subleases. Actual future cash requirements and lease abandonment costs may differ materially from the accrual at September 30, 2007,
particularly if actual sublease income is

significantly different from current estimates. These differences could have a material adverse effect on the Companys operating results and cash
position. For example, a reduction in assumed market lease rates of $0.25 per square foot per month for the remaining term of the lease, with all other assumptions remaining the same, would increase the estimated lease abandonment loss on the
Companys Sunnyvale, California headquarters by approximately $3.1 million as of September 30, 2007.

Other integration costs

Other integration costs for the year ended September 30, 2005 totaled $1.3 million and consisted primarily of legal and consulting
fees incurred in connection with integration activity related to the Companys merger with FreeMarkets.

Other arrangements

Other than the obligations identified above, the Company does not have commercial commitments under lines of credit, standby repurchase
obligations or other such debt arrangements. The Company has no other off-balance sheet arrangements or transactions with unconsolidated limited purpose entities, nor does it have any undisclosed material transactions or commitments involving
related persons or entities. The Company does not have any material noncancelable purchase commitments as of September 30, 2007.

Other accruals

During the fiscal years ended September 30, 2001 and 2000, the Company recorded certain accruals under
various sales commission arrangements. It is the Companys policy to reverse these accruals for these fiscal years as a reduction in expense based upon a number of factors including the expiration of California statute of limitations. During
the year ended September 30, 2006, the Company adjusted the accrual to reflect a revision in the scheduled release of these accruals. The reversal in the year ended September 30, 2006 includes $1.3 million related to the year ended
September 30, 2005. The Company has concluded that the effect of the error was not material to fiscal years 2006 and 2005. The Company reversed an additional $0, $4.2 million and $4.1 million from these accruals in the years ended
September 30, 2007, 2006 and 2005, respectively.

During fiscal year 2006, the County of Santa Clara in California examined the
Companys personal property tax returns for the 2001 through 2004 calendar years and assessed additional tax and interest of $3.3 million. The Company disagrees with the assessment and has appealed. The Company believes it has adequately
accrued for the potential outcome for this appeal.

Litigation

IPO Class Action Litigation

In 2001,
a number of purported shareholder class action complaints related to the Companys and FreeMarkets initial public offerings (the IPOs) were filed in the United States District Court for the Southern District of New York
against the Company and FreeMarkets, Inc. (FreeMarkets), and against certain of the two companies former officers and directors. These complaints were later consolidated into single class action proceedings related to each IPO. In
June 2003, a proposed settlement was reached between plaintiffs and the Company and FreeMarkets (the individual defendants having been previously dismissed). The Company merged with FreeMarkets in July 2004. In June 2005, the underwriters filed an
appeal of the District Courts order granting class certification in six focus cases. On December 5, 2006, the Court of Appeals issued an opinion, reversing the District Courts order granting class certification and finding that
plaintiffs cannot satisfy certain elements required for class actions. On June 25, 2007, in light of the Court of Appeals decision, the District

Court entered an order terminating the proposed settlement based on a stipulation among the parties to the settlement. On August 14, 2007, the
plaintiffs filed amended complaints in the focus cases, seeking to address the deficiencies raised in the Court of Appeals opinion. On September 27, 2007, plaintiffs moved to certify the classes in those focus cases. The parties are
currently discussing further discovery that the plaintiffs seek from the underwriters and the issuers. As of September 30, 2007, no amount is accrued as a loss is not considered probable or estimable.

Litigation Relating to Alleged Patent Infringement Disclosures Involving the Companys Chairman and Chief Executive Officer and Former President
and Director

On October 31, 2005, a purported class action, alleging violations of Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934, as amended, was filed in the United States District Court for the Eastern District of Virginia against the Companys Chairman and Chief Executive Officer and a former president and director of the Company. That case was
transferred to the United States District Court for the Northern District of California and an Amended Complaint was filed on November 30, 2006, adding the Company as a defendant. The action is brought on behalf of stockholders who
purchased the Companys stock from June 10, 2003 to February 7, 2005. A second amended complaint was filed on May 18, 2007. It alleges that the defendants artificially inflated the Companys stock price between those dates
by failing to disclose, in public statements that the Company made about its products, market position and performance, that some of those products allegedly infringed patents belonging to a third party. The defendants have filed a motion to
dismiss plaintiffs second amended complaint. The motion was heard by the Court on October 22, 2007. As of September 30, 2007, no amount is accrued as a loss is not considered probable or estimable.

Patent Litigation

In October 2006,
after an unsuccessful attempt to resolve the matter by negotiation, the Company was sued by Sky Technologies, Inc (Sky) for patent infringement in the United States District Court for the District of Massachusetts. The complaint (which
has been amended twice to add additional patents) does not specify which products are accused or what damages are claimed. Sky has served subsequent pleadings in the case contending that the Ariba Dynamic Trade and Ariba Sourcing software
products (whether hosted by the Company for specific customers or distributed to customers for installation at their sites), as well as certain other Ariba software products when used together with Ariba Sourcing software, infringe certain claims of
two of the U.S. patents owned by Sky. Sky seeks economic relief in the form of a royalty on the Company's sale of the accused products, other Ariba software products, and sourcing services, enhancement of damages, an attorneys fee award and an
injunction against further infringement. The total amount of the royalty now claimed by Sky before interest, enhancement or attorneys fees is approximately $30.8 million. Sky previously sought to add additional claims under a
certificate of correction for the third patent in suit, but on June 7, 2007, the Court denied its request to amend its pleading. Sky might seek to add those claims or other claims under other patents against the Company in a different
proceeding in the future. On October 30, 2007, the Court denied motions for summary judgment which had been filed by the Company. The case has been set for trial commencing on December 3, 2007. As of September 30, 2007, no amount is
accrued as a loss is not considered probable or estimable. In addition, Sky has filed a separate patent infringement action in the United States District Court for the Eastern District of Texas against Procuri (see Note 13 of Notes to Consolidated

Defending against these actions and various other claims and legal actions arising in the ordinary course of business may require significant management time and, regardless of the outcome, result in significant legal expenses. If the
Companys defenses are unsuccessful or if it is unable to settle on favorable terms, the Company could be liable for a large damages award and, in the case of patent litigation, subject to an injunction that could seriously harm its business
and results of operations.

The Company received an insurance reimbursement of $4.9 million in March 2006 for expenses incurred in
certain prior litigation matters. The amount was recorded as a credit to sales and marketing expense in the year ended September 30, 2006, which is where the incurred expenses were initially recorded.

The Company received $1.6 million, which is net of taxes of approximately $300,000, in the year ended September 30, 2006 related to the settlement
of a legal matter assumed in the merger with FreeMarkets. The amount was recorded as a credit to interest and other income, net in the year ended September 30, 2006.

Indemnification

The Company sells software licenses, access to its on-demand offerings and/or
services to its customers under contracts that the Company refers to as Terms of Purchase or Software License and Service Agreements (collectively, SLSA). Each SLSA contains the relevant terms of the contractual arrangement with the
customer, and generally includes certain provisions for indemnifying the customer against losses, expenses and liabilities from damages that may be incurred by or awarded against the customer in the event the Companys software or services are
found to infringe upon a patent, copyright, trade secret, trademark or other proprietary right of a third party. The SLSA generally limits the scope of remedies for such indemnification obligations in a variety of industry-standard respects,
including but not limited to certain product usage limitations and geography-based scope limitations, and a right to replace an infringing product or service or modify them to make them non-infringing. If the Company cannot address the infringement
by replacing the product or service, or modifying the product or service, the Company is allowed to cancel the license or service and return certain of the fees paid by the customer.

To date, the Company has not had to reimburse any of its customers for any losses related to these indemnification provisions and no material customer
claims for such indemnification are outstanding as of September 30, 2007.

Note 7Minority Interests in Subsidiaries

In December 2000, the Companys consolidated subsidiary, Nihon Ariba, issued and sold 38,000 shares, or approximately 41% of its common stock, for
cash consideration of approximately $40.0 million to Softbank pursuant to its strategic relationship with Softbank. In April 2001, Nihon Ariba issued and sold an additional 2% of its common stock for cash consideration of approximately $4.0 million
to third parties. Prior to the transactions, the Company held 100% of the equity of Nihon Ariba in the form of common stock.

In April
2001, the Companys consolidated subsidiary, Ariba Korea, issued and sold 3,800 shares, or approximately 42% of its common stock, for cash consideration of approximately $8.0 million to Softbank. Prior to the transaction, the Company held 100%
of the equity of Ariba Korea in the form of common stock.

In October 2004, the Company purchased the 41% interest in Nihon Ariba and the
42% interest in Ariba Korea held by Softbank for $3.5 million. See Note 12 for a discussion of the Softbank settlement. The Company subsequently purchased the additional 2% interest in Nihon Ariba held by various shareholders. These
transactions resulted in a $19.5 million reduction to minority interests during the year ended September 30, 2005.

For the year ended
September 30, 2005, the Company increased consolidated net loss by $17,000, which represented the minority interests share of income of the two subsidiaries.

Note 8Segment Information

The Company follows SFAS No. 131, Disclosures about Segments
of an Enterprise and Related Information, which establishes standards for reporting information about operating segments. Operating

##### Table of Contents

segments are defined as components of an enterprise about which separate financial information is available that is regularly evaluated by the chief
operating decision makers in deciding how to allocate resources and in assessing performance.

Owing to a change in internal reporting to
the chief operating decision makers during the three months ended December 31, 2005, the Company has three geographic operating segments: North America, EMEA and APAC. The segments are determined in accordance with how management views and
evaluates the Companys business and based on the aggregation criteria as outlined in SFAS No. 131. Future changes to this organizational structure or the business may result in changes to the reportable segments disclosed. The Company
markets its products in the United States and in foreign countries through its direct sales force and indirect sales channels.

The results
of the reportable segments are derived directly from the Companys management reporting system. The results are based on the Companys method of internal reporting and are not necessarily in conformity with accounting principles generally
accepted in the United States. Management measures the performance of each segment based on several metrics, including contribution margin. Asset data is not reviewed by management at the segment level.

Segment contribution margin includes all geographic segment revenues less the related cost of sales, direct sales and marketing expenses and regional
general and administrative expenses. A significant portion of each segments expenses arise from shared services and infrastructure that the Company has historically allocated to the segments in order to realize economies of scale and to use
resources efficiently. These expenses include information technology services, facilities and other infrastructure costs and are generally allocated based upon headcount.

Financial information for each reportable segment was as follows for the years ended September 30, 2007 and 2006. Comparative information for the year ended September 30, 2005 is not presented as it is not
practicable to do so (in thousands):

Revenues are attributed to countries based on the location of the Companys customers, with
some internal reallocation for multi-national customers. Certain revenue items are not allocated to segments because they are separately managed at the corporate level. These items include Ariba Managed Procurement Services and expense
reimbursement.

Contribution margin is used, in part, to evaluate the performance of, and allocate resources to, each of
the segments. Certain operating expenses are not allocated to segments because they are separately managed at the corporate level. These unallocated costs include marketing costs other than direct sales and marketing, research and development costs,
corporate general and administrative costs, such as legal and accounting, amortization of purchased intangibles, other incomeSoftbank, restructuring and integration (benefit) costs, interest and other income, net and provision for income
taxes.

The reconciliation of segment information to the Companys net loss before income taxes is as follows for the years ended
September 30, 2007 and 2006. Comparative information for the year ended September 30, 2005 is not presented as it is not practicable to do so (in thousands):

Note 9Stockholders Equity

1999 Equity Incentive Plan

The
Companys Board of Directors approved the 1999 Equity Incentive Plan (the Incentive Plan) on April 20, 1999. The Incentive Plan was amended on October 4, 2001. Any shares not issued under the Companys 1996 Stock Plan
(the 1996 Stock Plan) and any shares repurchased pursuant to the 1996 Stock Plan will also be available for grant under the Incentive Plan. The number of shares reserved under the Incentive Plan automatically increased on January 1
of each year until 2005 by the lesser of 3.3 million shares or 5% of the total number of shares of common stock outstanding on that date. Under the Incentive Plan, eligible employees, outside directors and consultants may be granted stock
options, stock appreciation rights, restricted shares or stock units. The exercise price for incentive stock options and nonstatutory options may not be less than 100% and 85%, respectively, of the fair value of common stock at the option grant
date. As of September 30, 2007, 7.4 million shares are available for grant under the Incentive Plan (including shares transferred from the 1996 Stock Plan since September 22, 1999).

1999 Directors Stock Option Plan

The Companys Board of Directors adopted the 1999 Directors Stock Option Plan (the Directors Plan) on April 20, 1999. The Directors Plan was amended effective May 19, 2000 and October 1,
2002. Each non-employee director received an option to purchase 12,500 shares of common stock upon joining the Board of Directors (the Initial Grant). In addition, each non-employee director received an option to purchase 2,500 shares of
common stock (the Annual Grant) upon the conclusion of each regular annual meeting of the Companys stockholders, provided the director continued serving as a member of the Board thereafter. However, a non-employee director did not
receive an Annual Grant in the same calendar year in which he or she received an Initial Grant. Each option had an exercise price equal to the fair value of the common stock on the grant date. The Directors Plan was terminated in April 2005.

Employee Stock Purchase Plan

The Companys Board of Directors adopted the Employee Stock Purchase Plan (the Purchase Plan) on April 20, 1999. The Purchase Plan was amended on August 1, 2006. Under the Purchase Plan, eligible employees may
purchase common stock in an amount not to exceed 1,000 shares per period. The purchase price per share equals 85% of the common stocks fair value at the end of the defined purchase period. As of September 30, 2007, there have been
4.7 million shares issued under the Purchase Plan and 960,000 shares are available for future issuance.

The Company has, in
connection with the acquisitions of TradingDynamics, Inc. (TradingDynamics), Tradex, Inc. (Tradex), SupplierMarket.com, Inc. (SupplierMarket) and FreeMarkets, assumed the stock option plans of each acquired
company.

TradingDynamics Stock Plans

On January 20, 2000, the Company assumed the TradingDynamics 1998 Stock Plan and 1999 Stock Plan (the TradingDynamics Plans). The TradingDynamics Plans were not approved by the Companys
stockholders. The TradingDynamics Plans provide for the grant of incentive stock options to employees at prices not less than 100% of the fair market value of the common stock on the date of grant, as determined by the Board of Directors, and for
the grant of nonstatutory stock options to employees and consultants at not less than par value. Generally, options were immediately exercisable, and the resulting shares issued to optionees were subject to certain repurchase rights, which were also
assumed by the Company. In January 2000, the Company reserved 274,908 shares for issuance upon the exercise of stock options assumed in connection with the acquisition of TradingDynamics. As of September 30, 2007, there were 1,359 shares
outstanding in connection with options

granted under the TradingDynamics Plans. As of September 30, 2007, no shares of the Companys common stock issued pursuant to the TradingDynamics
Plans were subject to repurchase by the Company. Options expire not later than ten years from the date of grant.

Tradex Stock Plans

On March 8, 2000, the Company assumed the Tradex 1997 Employee Stock Option Plan and 1999 Employee Stock Option/Stock Issuance
Plan (the Tradex Plans). The Tradex Plans were not approved by the Companys stockholders. The Tradex Plans provide for the grant of incentive stock options to employees and the grant of nonstatutory stock options or shares of
common stock to employees, board members and consultants at prices less than, equal to, or greater than the fair market value of the common stock on the date of grant, as determined by the Board of Directors. Generally, options were immediately
exercisable, and the resulting shares issued to optionees were subject to certain repurchase rights, which were also assumed by the Company. In March 2000, the Company reserved 315,233 shares for issuance upon the exercise of stock options assumed
with the acquisition of Tradex. As of September 30, 2007, there were 551 shares outstanding in connection with options granted under the Tradex Plans. As of September 30, 2007, no shares of the Companys common stock issued pursuant
to the Tradex Plans were subject to repurchase by the Company. Options expire not later than ten years from the date of grant.

SupplierMarket Stock Plan

On August 28, 2000, the Company
assumed the SupplierMarket 1999 Stock Option Plan (the SupplierMarket Plan). The SupplierMarket Plan was not approved by the Companys stockholders. The SupplierMarket Plan provides for the grant of incentive stock options to
employees at prices not less than 100% of the fair market value of the common stock on the date of grant, as determined by the Board of Directors, and the grant of nonstatutory stock options to employees and consultants at prices not less than the
par value of the common stock. Under the SupplierMarket Plan, options generally vest over a 48-month period at the rate of 12.5% of the grant after six months of service and 1/48thof the grant per month thereafter. Options expire not later than ten years from the date of grant. As of September 30, 2007, a total of 344,536 shares of the Companys common stock are reserved for issuance
upon the exercise of stock options assumed in connection with the acquisition of SupplierMarket or granted by the Company after the acquisition of SupplierMarket under the SupplierMarket Plan. As of September 30, 2007, there were 1,250 shares
outstanding in connection with options granted under the SupplierMarket Plan.

FreeMarkets Stock Plans

On July 1, 2004, the Company assumed the FreeMarkets, Inc. Second Amended and Restated Stock Incentive Plan and Broad Based Equity Incentive Plan
(the FreeMarkets Plans). The FreeMarkets Plans were not approved by the Companys stockholders. On October 11, 2007, the Compensation Committee of the Board of Directors of the Company amended and restated the Second Amended
and Restated Stock Incentive Plan. This Third Amended and Restated Stock Incentive Plan provides for the grant of stock units representing the equivalent of shares of Aribas common stock, the grant of incentive stock options to employees at
prices not less than 100% of the fair market value of the common stock on the date of grant and for the grant of nonstatutory stock options to employees, consultants, advisers and outside directors at a price determined by the Board of Directors.
The Broad Based Equity Incentive Plan provides for the grant of nonstatutory stock options to employees (other than officers), consultants and advisers at a price determined by the Board of Directors. Options expire not later than ten years from the
date of grant. As of September 30, 2007, a total of 7.8 million shares of the Companys common stock are reserved for issuance in connection with the acquisition of FreeMarkets or granted by the Company after the acquisition of
FreeMarkets under the FreeMarkets Plans. The number of shares reserved under the Third Amended and Restated Stock Incentive Plan automatically increases on October 1 of each year until 2007 by the lesser of 817,750 shares or 3% of the total
number of shares of common stock outstanding on that date. The number of shares reserved under the Broad Based Equity Incentive

The aggregate intrinsic value of shares outstanding and exercisable as of September 30, 2007
was $3.8 million. The aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Companys closing stock price on the last trading day of the fourth quarter of fiscal 2007 and the exercise price,
multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on September 30, 2007. This amount changes based on the fair market value of the Companys
stock. Total intrinsic value of options exercised for the years ended September 30, 2007, 2006 and 2005 was $1.8 million, $685,000 and $8.1 million, respectively. The weighted-average grant date fair value of options granted during the years
ended September 30, 2006 and 2005 was $4.30 and $4.87, respectively.

During the year ended September 30, 2005, the Company offered its employees the opportunity
to exchange outstanding stock options having an exercise price of $10.00 or more per share for restricted shares of its common stock. The number of newly issued restricted shares issued in exchange for the options was determined by application of
various exchange ratios based upon the exercise price of the options. The offer expired in August 2005 and resulted in the voluntary forfeiture of employee stock options to purchase 6.8 million shares of common stock in exchange for
2.6 million shares of restricted common stock, resulting in additional net deferred stock-based compensation of $15.0 million during fiscal year 2005. These amounts are amortized in accordance with FIN 28 over the three-year vesting period of
the individual restricted common stock grants.

In January 2005, the Company hedged anticipated cash flows from Ariba Korea using foreign currency
forward contracts (Korean Won) to offset the translation and economic exposures related to those cash flows. The Korean Won hedge minimized currency risk arising from cash held in Korean Won as a result of the Softbank settlement in October 2004.
The change in fair value of the Korean Won forward contract attributable to the changes in forward exchange rates (the effective portion) was previously reported in stockholders equity. In the year ended September 30, 2007, the Company
recorded a net realized gain of $2.2 million associated with the repatriation of cash from Ariba Korea and liquidation of the Ariba Korea entity, which is comprised of a $2.5 million gain from foreign currency translation adjustments and a $285,000
realized loss on the Korean Won cash flow hedge.

In the year ended September 30, 2007, the Company substantially liquidated
FreeMarkets s.a./n.v., a former Belgium FreeMarkets entity, resulting in a $425,000 realized gain from currency translation adjustments.

At September 30, 2007, 2006 and 2005, 622,000, 1.0 million and 2.5 million
potential common shares, respectively, consisting almost entirely of outstanding options, are excluded from the determination of diluted net loss per share, as the effect of such shares is anti-dilutive.

Note 11401(k) Savings Plan

Company employees
in the United States can participate in the 401(k) Plan. Participants can generally contribute up to 100% of their eligible compensation annually as defined by the plan document, subject to the section 402(g) limit as defined by the IRS. The Company
made a discretionary contribution in the form of common stock with a value of $2.5 million, $1.4 million and $0 in the years ended September 30, 2007, 2006 and 2005, respectively. The Company also made discretionary cash contributions of $0,
$841,000 and $2.6 million to the 401(k) Plan during the years ended September 30, 2007, 2006 and 2005, respectively.

Note 12Other
IncomeSoftbank

In September 2003, the Company commenced an arbitration proceeding against Softbank for failing to meet its
contractual revenue commitments. In October 2004, the Company entered into a definitive agreement with Softbank settling their dispute. A total of $37.0 million was recorded as Deferred incomeSoftbank in connection with the
settlement. As the Company was unable to determine the respective fair value of the amounts that related to Softbanks software license, related maintenance and the Companys prior agreements with Softbank, the $37.0 million will be
recognized ratably as Other incomeSoftbank over the three-year software license term ending in October 2007. The Company also made a provision for taxes of $4.8 million in the year ended September 30, 2005 as a result of the
settlement. The Company recorded other income of $13.6 million, $13.6 million and $9.5 million in the years ended September 30, 2007, 2006 and 2005, respectively. As of September 30, 2007 and 2006, deferred income related to the
Softbank settlement was $566,000 and $14.1 million, respectively.

Note 13Pending Acquisition of Procuri, Inc.

In September 2007, the Company announced that it had signed a definitive agreement (the Agreement) to acquire Procuri, a privately held
company headquartered in Atlanta, Georgia. Procuri is a provider of on-demand supply management solutions. Under the terms of the Agreement, the Company will pay $93.0 million in consideration at closing, consisting of equal amounts of cash and
common stock, of which $14.0 million of the cash will be placed in escrow to secure indemnity obligations of Procuri stockholders. The Company will also assume and payoff approximately $8.9 million of Procuris debt. The transaction is expected
to close in the latter part of the Companys first quarter of fiscal year 2008.

In connection with a review of the Companys deferred revenue accounts in the year ended
September 30, 2007, a $19.1 million adjustment was made to increase the September 30, 2006 deferred revenue, current and decrease deferred revenue, less current portion. The adjustment of deferred revenues corrected an error in the
classification between deferred revenue, current and deferred revenues, less current portion. Total deferred revenues were not impacted by the adjustment. The Companys previously reported deferred revenue, current had been understated and the
following tables describe the revisions made to interim consolidated financial statements previously issued during fiscal year 2007.

The Company has not amended its previously filed Annual Reports on Form 10-K or Quarterly Reports
on Form 10-Q for the correction of the error. Accordingly, the financial statements and related financial information contained in such reports should no longer be relied upon with respect to the Companys deferred revenue, current and deferred
revenue, less current portion, for the affected reporting periods. All referenced amounts for prior periods in the consolidated financial statements are presented on an as revised basis.

In the first quarter of fiscal year 2008, the Company evaluated its
office space in Sunnyvale, California, and determined that it will cease use of approximately 31,500 square feet of space in its corporate headquarters in the Companys first quarter of fiscal year 2008. In accordance with SFAS No. 146,
Accounting for Costs Associated with Exit or Disposal Activities, and SFAS No. 144, the Company will record a restructuring charge of approximately $5.0 million in the Companys first quarter of fiscal year 2008, covering

|ITEM 9A. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Evaluation of Disclosure Controls and
Procedures

As of the end of the period covered by this Annual Report on Form 10-K, we carried out an evaluation under the supervision
and with the participation of our Disclosure Committee and our management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to
Exchange Act Rule 13a-15(e). Disclosure controls and procedures are procedures that are designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, as amended (the Exchange
Act), such as this Form 10-K, is recorded, processed, summarized and reported within the time periods specified by the SEC. Disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to
our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

The evaluation of our disclosure controls and procedures included a review of their objectives and design, our implementation of them and their effect on the information generated for use in this Form 10-K. In the
course of the controls evaluation, we reviewed any data errors or control problems that we had identified and sought to confirm that appropriate corrective actions, including process improvements, were being undertaken. This type of evaluation is
performed on a quarterly basis so that the conclusions of management, including our Chief Executive Officer and Chief Financial Officer, concerning the effectiveness of the disclosure controls can be reported in our periodic reports on Form 10-K and
Form 10-Q. Many of the components of our disclosure controls and procedures are also evaluated on an ongoing basis by both our internal audit and finance organizations. The overall goals of these various evaluation activities are to monitor our
disclosure controls and procedures and to modify them as necessary. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period
covered by this report.

Managements Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act
Rule 13a-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting
as of September 30, 2007 based on the guidelines established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our internal control over financial
reporting includes policies and procedures designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with United States
generally accepted accounting principles.

Based on the results of our evaluation, our management concluded that our internal control over
financial reporting was effective as of September 30, 2007. We have reviewed the results of managements assessment with our Audit Committee.

Changes in Internal Control over Financial Reporting

As a result of remediating a material weakness in internal control
over financial reporting identified when assessing the effectiveness of our internal control over financial reporting as of September 30, 2006, we made a

##### Table of Contents

number of changes in our internal control over financial reporting in our most recently completed fiscal quarter that has affected, or is reasonably likely
to materially affect, our internal control over financial reporting. As a result of implementing these changes, during the year-end closing process, the Company determined that its historical method of classification between short-term and long-term
deferred revenue was not in accordance with generally accepted accounting principles (GAAP) and concluded that the Companys previously reported deferred revenue, current and total current liabilities had been understated.
Accordingly, management concluded that the previously issued annual and interim financial statements should be revised. Prior to the filing of this Form 10-K, the Company corrected its accounting for deferred revenue classifications. See also Notes
1 and 14 of Notes to Consolidated Financial Statements.

Except for the changes discussed above, there have been no significant changes in
our internal control over financial reporting during the most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.

Description of the Fiscal Year 2006 Material Weaknesses

As described in Item 9A of our prior year Annual Report on Form 10-K, management identified the following deficiencies, which in the aggregate, were deemed to represent a material weakness in our internal
control over financial reporting:

In fiscal year 2001, we abandoned a number of leased facilities as part of our corporate restructuring.
Included in the restructuring charges was the impairment of leasehold improvements made to these facilities. In preparing our consolidated financial statements for the fiscal year ended September 30, 2006, our management reconciled the amount
of the impaired leasehold improvements in our general ledger with our fixed assets register. The reconciliation identified that a total of $3.6 million of depreciation expense had been incorrectly recorded in fiscal years 2002 and 2003 for the
leasehold improvements impaired in fiscal year 2001.

The other significant deficiencies relate to the overaccrual of general accounts
payable and lease costs and our accounting for marketing development funds in fiscal years 2001 through 2003.

These deficiencies resulted
in an increase in property and equipment, net of $3.6 million and decreases in accounts payable of $1.9 million, accrued liabilities of $1.2 million and accumulated deficit of $6.7 million (increase to stockholders equity) as of
October 1, 2003 and decreases in net loss in years prior to fiscal year 2004. None of these adjustments impacted reported revenue or cash flow from operating activities during fiscal years 2001 through 2004.

Additionally, as identified during our ongoing efforts to perform enhanced analysis and documentation of certain balance sheet accounts, the Company
determined that its historical method of accounting for the net deferred revenue classification of short-term and long-term amounts was not in accordance with GAAP. As a result of changing its historical practices to conform to GAAP in the
classification of deferred revenue, management concluded that the Companys previously reported deferred revenue, current had been understated and that previously issued annual and interim consolidated financial statements should be revised.

Remediation of the Fiscal Year 2006 Material Weakness

During the year ended September 30, 2007, a more detailed analysis and documentation of certain of our balance sheet accounts was performed. Specifically the Company has enhanced its control environment to ensure
each key balance sheet account is subjected to detailed analysis, supported to appropriate underlying information, and reviewed by members of management. As a result, management has determined that the material weakness identified as of
September 30, 2006 has been remediated as of September 30, 2007.

Management Certifications

The certifications of our Chief Executive Officer and Chief Financial Officer required in accordance with Section 302 of the Sarbanes-Oxley Act of 2002 are attached as exhibits to this Annual Report on Form 10-K.
The disclosures set forth in this Item 9A contain information concerning (i) the evaluation of our disclosure controls and procedures referred to in paragraph 4 of the certifications, and (ii) material weaknesses in the design or
operation of our internal control over financial reporting referred to in paragraph 5 of the certifications. Those certifications should be read in conjunction with this Item 9A for a more complete understanding of the matters covered by the
certifications.

Inherent Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, do not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and
all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there
are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and
instances of fraud, if any, within a company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally,
controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the
likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of
compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of

Ariba, Inc.

We have audited Ariba Inc.s internal control over financial reporting as of September 30, 2007, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (the COSO criteria). Ariba, Inc.s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal
control over financial reporting. Our responsibility is to express an opinion on the Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists,
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis
for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those
policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,



92

##### Table of Contents

accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management
and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Ariba, Inc. maintained, in all material respects, effective internal control over financial reporting as of
September 30, 2007, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the consolidated balance sheets of Ariba, Inc. and the related consolidated statements of operations and comprehensive loss, stockholders equity, and cash flows for each of the two years in the
period ended September 30, 2007 and our report dated November 13, 2007 expressed an unqualified opinion thereon.
